The power tool 1, in particular the drive motor 3 of the power tool 1, can preferably also be operated via just one of the two rechargeable battery packs 21, 22. In the preferred exemplary embodiment, the two rechargeable battery packs 21, 22 are connected in series, however.
[0280] As shown in FIG. A1, the guide bar 4 comprises a longitudinal plane 31 spanned by the guide groove of the guide bar 4. In addition, the guide bar 4 comprises a longitudinal center axis 30. The longitudinal center axis 30 lies in the longitudinal plane 31. The longitudinal center axis 30 runs through the center of the guide bar 4, whereby the guide bar 4 in the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4 is divided by the longitudinal center axis 30 into approximately two parts of the same size. Furthermore, the guide bar 4 comprises a transverse plane 32. The transverse plane 32 is aligned orthogonal to the longitudinal plane 31 of the guide bar 4. The longitudinal center axis 30 lies in the transverse plane 32.
[0281] As shown in FIG. A1, the housing 2 has a front end 6 and a rear end 7. The guide bar 4 is arranged on the front end 6 of the housing 2. A fastening section 14 is provided on the rear end 7 of the housing 2. The fastening section 14 is provided for receiving the first rechargeable battery pack 21.

[0282] As shown in FIG. A1, the housing 2 comprises a central housing 47. The front end 6 of the housing 2 is formed on the central housing 47. The guide bar 4 projects at the front end 6 of the housing 2 out from the central housing 47 and extends in the direction from the rear end 7 of the housing 2 to the front end 6 of the housing 2. The power tool 1 comprises a guide bar fastener 75 for fastening the saw chain 5. In an operating state of the guide bar fastener 75, the guide bar 4 is held clamped on the housing 2, in particular on the central housing 47. In a released state of the guide bar fastener 75, the guide bar 4 can be moved in the direction of the longitudinal center axis 30 relative to the housing 2. The guide bar 4 can be pushed away from the housing 2 in the direction of its longitudinal center axis 30, whereby the saw chain 5 can be tensioned. If the guide bar fastener 75 is advantageously closed by means of a screw connection, the guide bar 4 is held clamped on the housing 2.
[0283] As shown in FIG. A1, the housing 2 of the power tool 1 comprises a motor housing 49. The drive motor 3 is arranged in the motor housing 49. In addition, the housing 2 comprises a handle housing 48. The power tool 1 comprises a first handle 9 on which a hand of the operator can rest. The first handle 9 is formed on the housing 2, in particular on the handle housing 48 of the housing 2. The rear end 7 of the housing 2 is preferably formed on the handle housing 48. The fastening section 14 is part of the handle housing 48. The central housing 47, the handle housing 48 and the motor housing 49 of the housing 2 are arranged adjacent to one another.
[0284] As shown in FIG. A1, the power tool 1 comprises an actuating element 10 for actuating the drive motor 3. The actuating element 10 is assigned to the first handle 9, i.e. that during normal operation of the power tool 1, the operator actuates the actuating element 10 with the hand that rests on the first handle 9. The power tool 1 comprises a, preferably mechanical, lockout lever 26. The lockout lever 26 is designed to lock the actuating element 10 in a locked position, preferably mechanically, and to release it in an operating position. If the operator wants to actuate the actuating element 10, they must first unlock the actuating element 10 by actuating the lockout lever 26. The operator can then actuate the actuating element 10 and control the drive motor 3.
[0285] As shown in FIG. A1, the power tool 1 comprises a cover clip 101. The cover clip 101 is part of the housing 2. The cover clip 101 engages around the actuating element 10 and is used to reinforce the housing 2. Furthermore, the power tool comprises a fastener 11. The fastener 11 has at least one fastening element 12 for holding the power tool 1 on the at least one fastening element 12. The operator is therefore able, for example, to fasten the power tool 1 via the fastening element 12 to a cord, whereby the power tool 1 can be secured against falling onto the ground. The particularly preferred embodiment of the power tool 1 has a protective device 80. The protective device 80 is designed such that it protects the rechargeable battery packs 21, 22 from impact loads, for example in the case of impact of the power tool 1 on the ground. Thus, damage to the rechargeable battery packs 21, 22 can be avoided.
[0286] As shown in FIG. A1, the power tool 1 comprises a second handle 57. The second handle 57 is provided for the operator's other hand to rest on.

The limiting device 60 is arranged between the guide bar 4 and the second handle 57. The limiting device 60 is designed such that the operator's hand is prevented from slipping from the second handle 57 in the direction of the guide bar 4.
[0287] FIG. A2 shows a further embodiment of the power tool 1 in a side illustration. The power tool 1 comprises a center of gravity S1. The center of gravity S1 lies in the first handle 9 the power tool 1 when the power tool 1 is in a state in which the first rechargeable battery pack 21 and the second rechargeable battery pack 22 are arranged on the fastening section 14. Such a weight distribution of the power tool 1 is particularly advantageous, since the operator grasps the first handle 9, and thus also the center of gravity S1, with one of their hands when using the power tool 1 as intended. As a result, the operator can easily hold the power tool 1 easily without having to correct any tilting moments of the power tool 1. Unpleasant moments of inertia are also avoided during operation of the power tool 1. In the preferred embodiment of the power tool 1, the fastening section 14 in particular is formed on the housing 2 in such a way that the first rechargeable battery pack 21 and the second rechargeable battery pack 22 are arranged favorably on the housing 2, whereby the center of gravity S1 of the power tool 1 lies in the first handle 9.
[0288] As shown in FIG. A2, the first handle 9 extends along a longitudinal direction 35. The longitudinal direction 35 of the first handle 9 corresponds to the direction of a longitudinal center axis 54 of the first handle 9. The first handle 9 comprises a grip region 53, in which the handle 9 can be grasped all the way around. In this grip region 53, the handle 9, in particular the handle housing 48, is designed in the form of a cylinder. The axis of the cylinder corresponds to the longitudinal center axis 54 of the first handle 9. The handle 9 itself extends along its longitudinal center axis from a rear end 77 up to its front end 76. The rear end 77 faces the rear end 7 of the housing 2. The front end 76 faces the front end 6 of the housing 2. The front end 6 of the handle 9 is determined by the section on the handle housing 48 at which the handle 9 can still be fully grasped by the operator's hand. The front end 6 is represented by a dashed line, along which the operator's index finger can grasp the handle housing 48. As shown in FIG. A2, the center of gravity S1 of the power tool 1 is thus right in front of the front end 6 of the handle 9, so that the operator's index finger can grasp the center of gravity S1 of the power tool 1 when operating the power tool 1 as intended. The rear end 77 of the handle 9 is formed in the present exemplary embodiment by a projection 78 with respect to the grip surface of the handle 9. In the present embodiment, the protective device 80 adjoins the projection 78.
[0289] As shown in FIG. A2, the transverse plane 32 of the guide bar 4 divides the housing 2 into an upper section 36 and into a lower section 37. The drive motor 3 is arranged with its center of gravity SM in the upper section 36. The center of gravity S1 of the power tool 1 lies in the lower section. Furthermore, a position vector g is shown in FIG. A2, as well as a horizontal, flat ground 112. The longitudinal center axis 30 of the guide bar 4 lies in a plane that is aligned parallel to the ground 112. The first rechargeable battery pack 21 and the second rechargeable battery pack 22 are also arranged in the lower section. The first rechargeable battery pack 21 has a center of gravity SA1. The second rechargeable battery pack 22 has a center of gravity SA2. The centers of gravity SA1, SA2 of the two rechargeable battery packs 21, 22 are arranged in the lower section 37 of the housing 2. The centers of gravity SA1, SA2 of the rechargeable battery packs 21, 22 therefore form a weight counterbalance to the center of gravity SM of the drive motor 3. In the exemplary embodiment, the fastening section 14 of the housing 2 also lies in the lower section 37 of the power tool 1.
[0290] As shown in FIG. A3, the power tool 1 comprises a longitudinal midplane 43. The longitudinal midplane 43 runs parallel to the longitudinal plane 31 of the guide bar 4 and bisects the housing 2. The housing 2 preferably has two housing halvesa first housing half 15 and a second housing half 16. Preferably, the parting plane of the first housing half 15 and the second housing half 16 corresponds to the longitudinal midplane 43 of the power tool 1.
[0291] As shown in FIG. A3, the centers of gravity SA1, SA2 of the rechargeable battery packs 21, 22 are preferably arranged on the longitudinal midplane 43. The power tool 1 is configured in such a way that the center of gravity S1 of the power tool 1 lies on the longitudinal midplane 43. The drive motor 3 is arranged in the housing 2, in particular in the motor housing 49, in such a way that the center of gravity SM of the drive motor 3 also lies in the longitudinal midplane 43 of the power tool 1. For this purpose, the drive motor 3 is aligned in such a way that its rotational axis 33 (FIG. A4) is parallel to the longitudinal plane 31 of the guide bar 4 or preferably lies in the longitudinal plane 31 of the guide bar 4. In the exemplary embodiment, the rotational axis 33 lies in the longitudinal midplane 43 of the power tool 1.
[0292] As shown in FIG. A4, the fastening section 14 is designed such that the rechargeable battery packs 21, 22 can be inserted in an insertion direction 34 into the fastening section 14. The insertion direction 34 corresponds preferably substantially to the longitudinal direction 35 of the first handle 9. To fasten the rechargeable battery packs 21, 22 in the fastening section 14 of the housing 2, they should be introduced in the insertion direction 34 until they make contact with a stop element 23, 24. The first stop element 23 of the fastening section 14 limits the movement of the first rechargeable battery pack 21 in the insertion direction 34. The second stop element 24 limits a movement of the second rechargeable battery pack 22 in the insertion direction 34. In the preferred exemplary embodiment, a latching connection is provided between the fastening section 14 and the rechargeable battery pack 21, 22, which latches into place when the rechargeable battery packs 21, 22 are inserted. Each rechargeable battery pack 21, 22 is provided with are two unlocking elements 111 (FIG.

[0294] As shown in FIG. A2, in the preferred exemplary embodiment, the first rechargeable battery pack 21 and the second rechargeable battery pack 22 are arranged offset from one another perpendicularly to the transverse plane 32 of the guide bar 4. Therefore, the fastening section 14 is designed such that when the power tool 1 is in a state in which the first rechargeable battery pack 21 and the second rechargeable battery pack 22 are inserted, a distance c, measured perpendicularly to the transverse plane 32, between the center of gravity SA1 of the first rechargeable battery packs 21 and the center of gravity S1 of the power tool 1 is smaller than a distance d, measured perpendicularly to the transverse plane 32, between the center of gravity SA2 of the second rechargeable battery pack 22 and the center of gravity S1 of the power tool 1. The distance c corresponds to at most 90% of the distance d.
[0295] As shown in FIG. A4, the actuating element 10 is arranged on the first handle 9 of the power tool 1. A distance q is provided between the actuating element 10 and the center of gravity S1 of the power tool 1, with the distance q in the exemplary embodiment not being greater than 3 cm, preferably not greater than 2 cm, in particular not greater than 1 cm. This means when the operator grasps the first handle 9 and actuates the actuating element 10, they also at least partially grasps the center of gravity S1 of the power tool 1. The center of gravity S1 of the power tool 1 in the preferred exemplary embodiment is between the second handle 57 and the actuating element 10.
[0296] As shown in FIG. A4, in the preferred embodiment of the power tool 1, the lockout lever 26 is arranged in the handle housing 48. In the exemplary embodiment, the lockout lever 26 is arranged outside the handle 9 (FIG. A2). The lockout lever 26 has a distance r from the center of gravity S1 of the power tool 1, in which case the distance r is not greater than 3 cm, preferably not greater than 2 cm, in particular not greater than 1 cm.
[0297] As shown in FIG. A4, in the preferred exemplary embodiment, the actuating element 10 is designed as a pivotable lever. The actuating element 10 is mounted so as to be able to pivot about a first pivot axis 38 with respect to the housing 2. The first pivot axis 38 is preferably aligned perpendicularly to the longitudinal plane 31 of the guide bar 4. The actuating element 10 comprises an outer contour 25. The outer contour 25 has a maximum first radius r1 with respect to the first pivot axis 38. In other words, the maximum first radius r1 corresponds to the maximum, radial extent of the actuating element 10 with respect to the first pivot axis 38. The actuating element 10 is arranged in the handle 9 in such a way that the maximum first radius r1 is greater than the distance e between the center of gravity S1 of the power tool 1 and the first pivot axis 38 of the actuating element 10. Thus, the center of gravity S1 of the power tool 1 lies very close to the pivot axis 38 of the actuating element 10.
[0298] As shown in FIG. A5, the lockout lever 26 is also designed as a pivotable lever. The lockout lever 26 is mounted so as to be able to pivot about a second pivot axis 39 with respect to the housing 2. The pivot axis 39 of the lockout lever 26 preferably lies in a plane aligned parallel to the longitudinal plane 31 of the guide bar 4. The pivot axis 39 of the lockout lever 26 preferably lies in the longitudinal midplane 43 of the housing 2. The lockout lever 26 has an outer contour 27, wherein the outer contour 27 has a maximum second radius r2 with respect to the second pivot axis 39. The maximum second radius r2 is greater than a distance f between the center of gravity S1 of the power tool 1 and the second pivot axis 39. Thus, the center of gravity S1 lies in the viewing direction of the second pivot axis 39 of the lockout lever 26 inside the maximum second radius r2 of the lockout lever 26. During normal operation of the power tool 1, it is provided that the operator actuates the lockout lever 26 by means of their thumb. The position of the center of gravity S1 of the power tool 1 now means that the operator grasps the center of gravity S1 with both their thumb and with their index finger. Consequently, the operator grips the power tool 1 directly at the center of gravity S1, thereby ensuring particularly ergonomic handling of the power tool 1.
[0299] FIGS. A6 and A7 show the exemplary embodiment of the power tool 1 according to FIG. A2. The view according to FIG. A2 of the power tool 1 is shown again in FIG. A7 for reasons of better clarity.
[0300] As shown in FIG. A6 and 7, the first handle 9 comprises a first handle section 55 on which the operator's hand can rest, in particular for grasping the first handle 9. The handle section 55 has a top side 51 and a bottom side 52 facing away from the top side 51. The top side 51 of the handle section 55 faces away from the actuating element 10. The bottom side 52 of the handle section 55 faces the actuating element 10. Preferably, the actuating element 10 is arranged in the housing 2 in such a way that the actuating element projects out of the housing 2 directly at an opening in the bottom side 52 of the handle section 55.
[0301] As shown in FIGS. A6 and A7, the cover clip 101 extends from its first end 103 to its second end 104 along the bottom side 52 of the first handle section 55. In the exemplary embodiment, the cover clip 101 extends substantially parallel to the bottom side 52 of the first handle section 55. The actuating element 10 is thus arranged between the handle 9, in particular the handle section 55, and the cover clip 101. The first front end 103 of the cover clip 101 is directly adjacent to the motor housing 49 and to the central housing 47 of the housing 2. The cover clip 101 separates the handle housing 48 from the motor housing 49 and the central housing 47. The second end 104, i.e. the rear end of the cover clip 101, leads into the handle housing 48 of the housing 2, in particular into the fastening section 14 of the handle housing 48. The handle housing 48 and the cover clip 101 form an opening 110, through which the operator's fingers can reach when they grip the handle section 55. The cover clip 101 serves to reinforce the housing 2. In particular, if great forces and torques are acting on the housing 2, it is particularly advantageous that owing to the cover clip 101 the corresponding loads are also absorbed via the cover clip 101, thus avoiding damage to the housing 2. Advantageously, the cover clip 101 is designed integrally with the central housing 47 and/or the handle housing 48.
[0302] As shown in FIG. A6, the cover clip 101 has a taper 102 in the direction of its second end 104. The taper 101 allows the operator to fasten the power tool 1 via a carabiner 113 or another locking element to a carrying device. The carabiner 113 is schematically illustrated in FIG. A6 by dashed lines.
[0303] As shown in FIG. A8, the cover clip 101 extends in the direction perpendicular to the longitudinal plane 31 of the guide bar 4 from a first longitudinal side 108 of the power tool 1 to a second longitudinal side 109 of the power tool 1. The cover clip 101 comprises a maximum width k, measured perpendicularly to the longitudinal plane 31, which corresponds to the maximum distance between the first longitudinal side 108 of the power tool 1 and the second longitudinal side 109 of the power tool 1. Furthermore, the cover clip 101 has a minimum width l at its taper 102, with the minimum width l of the taper 102 corresponding to the minimum distance between the first longitudinal side 108 and the second longitudinal side 109. The minimum width l corresponds to at most 70%, preferably at most 60%, in particular approximately 50% of the maximum width k of the cover clip 101. In the preferred exemplary embodiment, the minimum width l of the cover clip 101 at the taper 102 corresponds to at least 10%, preferably at least 20%, particularly preferably at least 30%, preferably at least 40% of the maximum width k of the cover clip 101.
[0304] As shown in FIG. A8, the lockout lever 26 is arranged between the first longitudinal side 108 and the second longitudinal side 109 of the cover clip 101 in the direction perpendicular to the longitudinal plane 31 of the guide bar 4. The lockout lever 26 is preferably designed and arranged in the housing 2 in such a way that it does not project beyond either the first longitudinal side 108 nor the second longitudinal side 109 at the broadest point of the cover clip 101 in the direction perpendicular to the longitudinal plane 31 of the guide bar 4. The outer contour 27 of the lockout lever 26 is arranged completely between the first longitudinal side 108 and the second longitudinal side 109 of the cover clip 101 in the direction perpendicular to the longitudinal plane 31 of the guide bar 4, at least in the region of the first end 103 of the cover clip 101. The outer contour 27 of the lockout lever 26 extends perpendicularly to the longitudinal plane 31 of the guide bar 4, measured over a maximum width m, wherein the maximum width m of the outer contour 27 is less than the maximum width k of the cover clip 101. The lockout lever 26 is preferably rotatably mounted and has two actuating sections for left-side and right-side use.
[0305] As shown in FIGS. A6 and A7, the housing 2 comprises a bridge 107. The bridge 107 extends from the first handle section 55 to the cover clip 101. The bridge extends preferably from the bottom side 52 of the first handle section 55 to a top side 105 of the cover clip 101. The top side 105 of the cover clip 101 faces the bottom side 52 of the first handle section 55. In addition, the cover clip 101 comprises a bottom side 106 facing away from the top side 105. The bridge 107 divides the opening 110 bounded by the handle 9 and the cover clip 101 into a first opening 110 and a second opening 110. The actuating element 10 is arranged between the bridge 107 and the first end 103 of the cover clip 101. The actuating element 10 projects into the first opening 110. The taper 102 of the cover clip 101 is arranged between the bridge 107 and the second end 104 of the cover clip 101. Therefore, the taper 102 of the cover clip 101 partially bounds the second opening 110.
[0306] As shown in FIG. A7, the cover clip 101 has a length n. The length n corresponds to the distance, measured in the longitudinal direction 35 of the first handle 9, between the first end 103 of the cover clip 101 and the second end 104 of the cover clip 101. Furthermore, a distance p, measured in the longitudinal direction 35 of the first handle 9, between the bridge 107 and the first end 103 of the cover clip 101 corresponds to at most 50%, in particular at most 40% of the length n of the cover clip 101. A distance o, measured in the longitudinal direction 35 of the first handle 9, between the bridge 107 and the second end 104 of the cover clip 101 corresponds to at least 40%, preferably at least 50% of the length n of the cover clip 101.
[0307] As also shown in particular in FIG. A6, the hand-held power tool 1 comprises the protective device 80 to protect the rechargeable battery packs 21, 22. The protective device 80 is arranged on the fastening section 14 of the rechargeable battery packs 21, 22.
[0308] As shown in FIG. A9, the first rechargeable battery pack 21 extends in its longitudinal direction 85 (FIG. A7, FIG. A9) from a first end face 86 to a second end face 87. The second rechargeable battery pack 22 also extends in its longitudinal direction 85 from a first end face 86 to a second end face 87. The rechargeable battery packs 21, 22 preferably have a substantially triangular cross-sectional contour 88, 88 with rounded corners 99, 99. The rechargeable battery packs 21, 22 also have a shoulder 100, 100 that serves as a stop when the rechargeable battery packs 21, 22 are being slid into the fastening section 14 of the power tool 1. A cross-sectional area of the rechargeable battery packs 21, 22 in a region between the second end face 87, 87 and the shoulder 100, 100 is greater than a cross-sectional area of the rechargeable battery packs 21, 22 in a region between the shoulder 100, 100 and the first end face 86, 86. When the power tool 1 is in a state in which the rechargeable battery packs 21, 22 are installed in the fastening section 14, the first end face 86, 86 of the rechargeable battery packs 21, 22 faces the fastening section 14. The second end face 87, 87 of the rechargeable battery packs 21, 22 faces away from the fastening section 14. When the rechargeable battery packs 21, 22 are inserted, the second end faces 87, 87 form the free end faces of the rechargeable battery packs 21, 22. By contrast, when the rechargeable battery packs 21, 22 are inserted, the first end faces 86, 86 are concealed by the fastening section 14. The first rechargeable battery pack 21 and the second rechargeable battery pack 22 each have a longitudinal axis 50, 50 running in the longitudinal direction 85, 85 of the respective rechargeable battery pack 21, 22. The longitudinal axes 50, 50 of the rechargeable battery packs 21, 22 run along the centroidal axes of the cross-sectional planes of the rechargeable battery pack 21, 22, which are aligned approximately parallel to the end faces 86, 86, 87, 87. The first rechargeable battery pack 21 and the second rechargeable battery pack 22 are preferably of identical construction. Furthermore, FIG. A9 also indicates the unlocking elements 111, 111 of the rechargeable battery packs 21, 22 for locking and unlocking the latching connection between the rechargeable battery packs 21, 22 and the fastening section 14.
[0309] As shown in FIGS. A6 and A7, the protective device 80 comprises at least one first cover element 81. The at least first cover element 81 extends in the longitudinal direction 85 of the first rechargeable battery pack 21 in the installed state at least to the second end face 87 of the first rechargeable battery pack 21. The longitudinal direction 85, 85 of the rechargeable battery packs 21, 22 corresponds in the installed state preferably to the insertion direction 35 the rechargeable battery packs 21, 22, in particular the longitudinal direction 43 of the first handle 9. The protective device 80 comprises a second cover element 82. The second cover element 82 extends in the longitudinal direction 85 of the second rechargeable battery pack 22 in the installed state of the rechargeable battery pack 22 at least to the second end face 87 of the second rechargeable battery pack 22.
[0310] As shown in FIG. A6 to A8, the rechargeable battery packs 21, 22 are slid into the fastening section 14. In one preferred embodiment, in the installed state of the rechargeable battery packs 21, 22, the longitudinal axes 50, 50 lie in the longitudinal midplane 43 of the housing 2. In the preferred exemplary embodiment, the longitudinal axes 50, 50 of the rechargeable battery packs 21, 22 are arranged parallel to the longitudinal plane 31 of the guide bar 4. As shown in particular in FIG. A7, in the installed state of the rechargeable battery packs 21, 22, the rechargeable battery packs 21, 22 are arranged offset from one another in their longitudinal direction. The second end faces 87, 87 of the rechargeable battery packs 21, 22 lie in different planes. In a transverse direction 91, the rechargeable battery packs 21, 22 are arranged one above the other. The transverse direction 91 is aligned perpendicular to the longitudinal direction 85 of the first rechargeable battery pack 21 and/or to the longitudinal direction 85 of the second rechargeable battery pack 22. The transverse direction 91 is in a plane that is aligned parallel to the longitudinal midplane 43 of the housing 2. In the preferred exemplary embodiment, in the installed state the rechargeable battery packs 21, 22, the longitudinal axes 50, 50 of the rechargeable battery packs 21, 22 are aligned parallel to one another. As schematically indicated in FIG. A7, it may also be expedient if the fastening section 14 is designed in such a way that, in the installed state of the rechargeable battery packs 21, 22, the longitudinal axes 50, 50 of the rechargeable battery packs 21, 22 are arranged at an angle to one another. The second rechargeable battery pack 22 is schematically illustrated by a dashed line.
[0311] In the preferred exemplary embodiment, the longitudinal axes 50, 50 of the two rechargeable battery packs 21, 22 lie in a plane that is aligned parallel to the longitudinal midplane 43 of the housing 2. Preferably, the longitudinal axes 50, 50 of the two rechargeable battery packs 21, 22 lie in the longitudinal midplane 43 of the housing 2.
[0312] As shown in particular in FIG. A10, the protective device 80 comprises a third cover element 83 and a fourth cover element 84. As shown in FIGS. A7 and A8, in the preferred exemplary embodiment, the third cover element 83 and/or the fourth cover element 84 extends in the longitudinal direction 85, 85 of the rechargeable battery packs 21, 22 at least to the second end face 87, 87 of the rechargeable battery packs 21, 22. As shown in FIG. A10, the first cover element 81 is arranged on a rounded corner 99 of the first rechargeable battery pack 21 that faces away from the second rechargeable battery pack 22. The second cover element 82 is arranged on a rounded corner 99 of the second rechargeable battery pack 22 that faces away from the first rechargeable battery pack 21. Preferably, the first cover element 81 and the second cover element 82 are each designed to be symmetrical to the longitudinal midplane 43.
[0313] As shown in FIG. A7, the third cover element 83 and the fourth cover element 84 are arranged in a transverse direction 91 between the rechargeable battery packs 21, 22 (FIG. A7). As shown in FIG. A10, the third cover element 83 and the fourth cover element 84 are formed opposite one another in relation to a plane aligned parallel to the longitudinal plane 31 of the guide bar, in particular in relation to the longitudinal midplane 43. Particularly preferably, the third cover element 83 and the fourth cover element 84 are designed to be symmetrical to one another in relation to the longitudinal midplane 43.
[0314] As shown in FIG. A6 and 7, the protective device 80 has cutouts 90 between the cover elements 81, 82, 83, 84 for gripping the rechargeable battery packs 21, 22. In particular, the unlocking elements 111, 111 are freely accessible in the cutouts 90 to the operator, whereby the unlocking elements 111, 111 can be actuated by the operator and the rechargeable battery packs 21, 22 can be pulled out of the fastener 14.
[0315] As shown in FIGS. A4 and A10, movement gaps 92 are provided between the cover elements 81, 82, 83, 84 and the rechargeable battery packs 21, 22. The movement gaps 92 taper in the direction of the first end face 86, 86 of the rechargeable battery packs 21, 22. The rechargeable battery packs 21, 22 are particularly well protected by the movement gaps 92, since the cover elements 81, 82, 83, 84 in the region of the movement gaps 92 are elastically deformed when force is applied to the protective device 80 and in the process the energy applied to the protective device 80 can dissipate, without any force being applied to the rechargeable battery packs 21, 22.
[0316] As shown in FIG. A11, the first cover element 81 and/or the second cover element 82 of the protective device 80 has a width i measured perpendicularly to the longitudinal plane 31 of the guide bar 4. The width i corresponds to at least 30%, preferably at least 50% of the width jmeasured perpendicular to the longitudinal plane 31 of the guide bar 4of the first rechargeable battery pack 21 and/or the second rechargeable battery pack 22.
[0317] As shown in FIG. A7, the third cover element 83 and/or the fourth cover element 84 comprise a rear protective contour 93 and a front protective contour 94. The rear protective contour 93 is adjacent in the longitudinal direction 85 of the first rechargeable battery pack 21 to the second end face 87 of the first rechargeable battery pack 21 and the front protective contour 94 is adjacent in the longitudinal direction 85 of the second rechargeable battery pack 22 to the second end face 87 of the second rechargeable battery pack 22. The front protective contour 93 is connected to the rear protective contour 94 via a shoulder 95. The mutually facing inner faces of the rechargeable battery packs 21, 22 are protected by the third cover element 83 and the fourth cover element 84.
[0318] As shown in FIG. A10, the third cover element 83 and/or the fourth cover element 84 have an outer face 97, 97 facing away from the rechargeable battery packs 21, 22. The outer face 97, 97 has a concave curvature 98, 98. The concave curvature 98, 98 projects between the rechargeable battery packs 21, 22. As a result, the contours of the third cover element 83 and the fourth cover element 84 follow the outer contour of the rechargeable battery packs 21, 22, thereby guaranteeing that the rechargeable battery packs 21, 22 are better protected.
[0319] Several illustrations of the power tool 1 according to FIG. A2 are shown in FIGS. A12 to A14, in which the fastener 11 is shown. The fastener 11 is used to secure the power tool 1 and to protect it from being accidentally dropped by the operator. Thus, for example, the power tool 1 can be fastened via the fastener 11 to an end of a cord, while the other end of the cord is held, for example, on a carrying device of the operator. If the operator drops the power tool, it is secured via the cord, thus preventing the power tool 1 from hitting the ground.
[0320] As shown in FIGS. A12 to A14, in the preferred exemplary embodiment the fastener 11 is arranged on the handle housing 48 of the housing 2. The fastener 11 has at least one first fastening element 12 for holding the power tool 1 on the first fastening element 12. In the preferred exemplary embodiment, the fastener 11 has a second fastening element 13 for holding the power tool 1 on the second fastening element 13. The fastener 11 is designed such that the power tool 1 can be held on the first fastening element 12 and/or on the second fastening element 13. In the preferred exemplary embodiment, the fastening elements 12, 13 are designed as eyelets. Other configurations of the fastening elements 12 may also be expedient.
[0321] As shown in particular in FIG. A12, the fastener 11 is designed such that the fastening elements 12, 13 are outside of the housing 2. The fastener 11 is designed such that the fastening elements 12, 13 are accessible to the operator. The first fastening element 12 is arranged on the first housing half 15 of the housing 2. The second fastening element 13 of the fastener 11 is arranged on the second housing half 16 of the housing 2.
[0322] As shown in particular in FIG. A12, the housing 2 has a first longitudinal outer side 28 and a second longitudinal outer side 29. The longitudinal outer sides 28, 29 are arranged opposite one another with respect to a plane aligned parallel to the longitudinal plane 31 of the guide bar 4, in particular with respect to the longitudinal midplane 43. The first fastening element 12 is arranged on the first longitudinal outer side 28 of the housing 2. The second fastening element 13 is arranged on the second longitudinal outer side 29 of the housing 2.
[0323] As shown in FIG. A12, the fastener 11 comprises a base body 44. The base body 44 of the fastener 11 is flat, as shown in FIG. A12 to 14. The base body 44 can alternatively also have another form, for example, curved, bulging or similar. The base body 44 extends in a longitudinal direction 45 from a first longitudinal end 46 up to a second longitudinal end 46. As shown in FIG. A12, a fastening element 12, 13 is formed on at least one of the two longitudinal ends 46, 46, preferably on both longitudinal ends 46, 46 of the base body 44. Preferably, in each case a fastening element 12, 13 is formed on each longitudinal end 46, 46. The longitudinal direction 45 of the base body 44 is aligned approximately perpendicular to the longitudinal plane 31 of the guide bar 4. As shown in FIG. A12, wing-like projections 19, 20 are provided on the base body 44, with the wing-like projections 19, 20 being arranged between the fastening elements 12, 13. The wing-like projections 19, 20 of the base body 44 extend transversely to the longitudinal direction 45 of the base body 44.
[0324] As shown in FIG. A12 to 14, the fastener 11 is arranged in the fastening section 14 of the housing 2. The fastener 11 is held between the first housing half 15 and the second housing half 16. In the preferred exemplary embodiment according to FIGS. A12 to A14, the fastener 11, in particular the base body 44 of the fastener 11, is held in a form-fitting manner between the first housing half 15 and the second housing half 16. The two housing halves 15, 16 form a slot-like recess 17, in which the fastener 11 is held with a form fit. In an alternative embodiment, it may also be expedient to fasten the base body 44 in the housing 2 in some other way, for example glue it in, etc. The fastener 11 is particularly preferably arranged between the first rechargeable battery pack 21 and the second rechargeable battery pack 22. The fastener 11, in particular the base body 44 of the fastening section 14, is made as a single part, whereby high forces can be transmitted via the base body to the housing 2. The wing-like projections 19, 20 are advantageous in particular when absorbing tilting moments of the base body 44 around the longitudinal axis 45 of the base body 44.
[0325] If the power tool 1 is caught by a cord or by the fastener 11 in the event of a fall, high forces must be transmitted from the fastener 11 to the housing 2. This creates high loads on the housing 2. Therefore, a mechanical connection, in particular a screw connection 18, is provided close to the fastener 11 for connecting the first housing half 15 and the second housing half 16. The distance between the mechanical connection and the fastener 11 in the exemplary embodiment is less than 3 cm, preferably less than 2 cm, particularly preferably less than 1 cm. As a result, the forces transmitted by the fastener 11 to the housing halves 15, 16 of the housing 2 can be supported by the mechanical connection. Provision can also be made to provide several mechanical connections close to the fastener 11.
[0326] As shown in FIG. A2, the fastener 11 is arranged between the rear end 7 of the housing 2 and the center of gravity S1 of the power tool 1. If the power tool 1 hangs via its fastener 11 on a cord, for example, then the front end 6 of the power tool 1, in particular its guide bar 4, points in the direction of the ground. Consequently, the operator can easily grip the power tool 1 from above.
[0327] As shown in FIG. A15, the second handle 57 of the housing 2 has a second handle section 58 on which the operator's other hand can rest. The second handle section 58 is formed on the motor housing 49 of the housing 2. The second handle section 58 is formed from a bearing surface of the motor housings 49 that extends in a longitudinal direction 59 of the second handle section 58 from a rear end 73 to a front end 72 of the handle section 58. The bearing surface has approximately the shape of a cylinder segment over its entire length, wherein the direction of the cylinder axis corresponds to the longitudinal direction of the second handle section 58. The diameter of the cylinder corresponds to approximately the width of the motor housing 49 measured perpendicularly to the longitudinal plane 31. The cylinder segment corresponds to approximately a half cylinder. In an alternative embodiment (not shown in more detail) of the power tool 1, it can also be provided that hollow-like depressions are formed on the bearing surface of the handle section 58, said depressions being provided to support and for the ergonomic positioning of the individual fingers.
[0328] As shown in FIG. A15, the limiting device 60 is provided between the second handle section 58 and the guide bar 4. The limiting device 60 has an elevation 61 with respect to the second handle section 58, said elevation extending at least within the longitudinal plane 31 of the guide bar 4. In the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4, the elevation 61 extends, starting from the handle section 58, perpendicularly to the longitudinal direction 59 of the handle section 58 away from the handle section 58. The elevation 61 is designed such that the operator's hand is prevented from slipping from the second handle section 58 in the direction of the guide bar 4. The elevation 61 is designed such that the elevation 61 forms a form-fitting stop in the direction of the guide bar 4 for the operator's hand that is resting on the second handle section 58.
[0329] As shown in FIG. A15, in the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4, the limiting device 60 has an outer contour 62. The outer contour 62 of the limiting device 60 has a first end 63 adjoining the second handle section 58 and a second end 64 adjacent to the guide bar 4. The elevation 61 is formed on the first end 63 of the outer contour 62. The elevation 61 consequently extends from the first end 63 of the outer contour 62 in the direction away from the handle section 58. The elevation 61 has a contact section 65. The contact section 65 is provided to support the operator's hand which rests on the second handle section 58. The contact section 65 of the elevation is designed such that the hand resting on the second handle section 58 comes into contact, in particular form-fitting contact, with the contact section 65 if the hand moves in the longitudinal direction 59 of the second handle section 58. The contact section 65 of the elevation 61 thus forms a stop towards the guide bar 4 for the hand resting on the second handle 57 in the longitudinal direction 59 of the second handle section 59. The contact section 68 is concave. The contact section 65 forms an undercut for a hand of the operator resting on the contact section 65. If the operator's hand is in contact with the contact section 65 and the hand moves, in the viewing direction perpendicular to the longitudinal plane 31, perpendicularly to the longitudinal direction 59 away from the handle section 58, the operator's hand is caught on the contact section 65 due to the undercut of the bearing surface 65. The contact section 65 has the form of a hollow, into which the operator's hand resting on the second handle section 58 of the second handle 57 molds itself when moving in the longitudinal direction 59 of the handle section 58.
[0330] As shown in FIG. A15, an edge 68 is formed on the contact section 65. The edge 68 is formed by a channel 69. The channel 69 forms the housing boundary between the motor housing 49 and the central housing 47. The power tool 1 comprises a lubricant tank 70 for supplying the saw chain 5 with lubricant. The lubricant tank 70 is part of the housing 2, in particular part of the central housing 47. The limiting device 60 is preferably formed at least partially from the wall of the lubricant tank 70.
[0331] As shown in FIG. A15, in the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4, the elevation 61 has a height h measured perpendicularly to the longitudinal direction 59 of the second handle section 58 at the first end 63 of the outer contour 62. The height h corresponds to at least 15%, in particular at least 20%, preferably approximately 25% of a length l, measured in the longitudinal direction 59 of the second handle section 58, of the second handle section 58. The length l corresponds to the distance between the front end 72 and the rear end 73 of the handle section 58.
[0332] As shown in FIG. A15, the concave contact section 65 ends at a further edge 74 of the elevation 61. At this further edge 74, the elevation 61 has its maximum height in relation to the handle section 58. The contact section 65 is designed such that, in the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4, a tangent 75 to the contact section 65 at the edge 74 intersects a straight line in the direction of the longitudinal direction 59 of the second handle section 58 at an angle . The angle is open towards the second handle section 58 and is at most 90, preferably at most 80, in particular approximately 75. Preferably, the angle is more than 30.
[0333] As shown in FIG. A15 shown, the housing 2 in the region of the second handle section 58 is open towards the top. Therefore, in the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4, the housing 2 is open in the direction perpendicular to the longitudinal direction 59 of the second handle section 58, away from the handle section 58. Thus, the operator can easily the second handle section 58 from above. In an alternative embodiment not shown in more detail, the contact section 65 is provided with an anti-slip coating. In a preferred embodiment, a grip detector (not shown in more detail) is provided on the second handle 57. The grip detector can be mechanical and/or electrical and/or electronic. An electronic grip detector is preferably in the form of a resistive, capacitive or inductive grip detector. The mechanical and/or electrical signal of such a grip position detector can be used as an enable signal for actuating the drive motor 3. Such a signal can also be used in conjunction with a dead man's switch. The person skilled in the art can use such a signal in various ways for functions known from the prior art.
[0334] FIG. A16 shows the power tool with the rechargeable battery packs 21, 22 having been removed. Thus, the rechargeable battery packs 21, 22 can be charged in external charging stations and then inserted back into the power tool 1.
[0335] As shown in particular in FIG. A16, raised elements 114 can be provided on the lubricant tank 70. The raised elements 114 form elevations starting from the lubricant tank 70. In the present exemplary embodiment, three raised elements 114 are provided. In the present case, the raised elements 114 have a substantially triangular outer contour with respect to the viewing direction perpendicular to the longitudinal plane 31 of the guide bar 4. Other outer contours may also be expedient. In the preferred exemplary embodiment, the raised elements 114 are arranged one behind the other in series with respect to the direction of the longitudinal center axis 30. The three raised elements 114 lie in the longitudinal midplane 43. Other arrangements on the top side of the lubricant tank 70 may also be expedient.
[0336] As likewise shown in FIG. A16, the power tool 1 preferably comprises a connection unit 115. The connection unit 115 is designed to store, send and/or receive data to/from the power tool 1. Such data can be, for example, the overall run time of the power tool 1. If a predetermined threshold for the run time is reached, the operator can be informed that maintenance is required. Furthermore, the position of the power tool 1 can also be determined and communicated to other devices via the connection unit 115.
[0337] An alternative embodiment of the power tool 1 is shown in FIG. A17. This embodiment differs from the power tool 1 according to the previous figures merely in that no protective device 80 is provided for the rechargeable battery packs 21, 22. Therefore, the housing 2 ends with the fastening section 14, into which the rechargeable battery packs 21, 22 are inserted.
[0338] A further embodiment of the electrical, hand-guided power tool 1 is shown in FIGS. A18 to A22. The same reference signs show the same components of the power tool 1. The hand-held power tool 1 comprises the housing 2 and the drive motor 3 arranged in the housing 2, wherein the fastening section 14 for receiving the first rechargeable battery pack 21 for supplying the drive motor 3 with electrical energy is provided on the rear end 7 of the housing 2. Furthermore, the power tool 1 comprises at least the first rechargeable battery pack 21 and in particular the second rechargeable battery pack 22, with the first rechargeable battery pack 21 and in particular the second rechargeable battery pack 22 being held on the fastening section 14. The first rechargeable battery pack 21 and in particular the second rechargeable battery pack 22 extend in their longitudinal direction 85, 85 from their first end face 86, 86 to their second end face 87, 87, wherein the first end face 86, 86 of the first rechargeable battery pack 21 and in particular the second rechargeable battery pack 22 faces the fastening section 14 and the second end face 87, 87 of the first rechargeable battery pack 21 and in particular the second rechargeable battery pack 22 faces away from the fastening section 14. The power tool 1 comprises a fixing device 130, wherein the fixing device 130 engages at least partially around the second end face 87 of the first rechargeable battery pack 21 and in particular of the second rechargeable battery pack 22, wherein the fixing device 130 is releasably held on the housing 2, in particular on the fastening section 14.
[0339] As shown in FIG. A19, the fixing device 130 comprises a first fixing section 131 and a second fixing section 132. The first fixing section 131 forms a receiving space in which the first rechargeable battery pack 21 is arranged. The fixing device 130 bears with its first fixing section 131 against the second end face 87 of the first rechargeable battery pack 21 and in particular against the longitudinal side of the first rechargeable battery pack 21. The second fixing section 132 forms a further receiving space in which the second rechargeable battery pack 22 is arranged. The fixing device 130 bears with its second fixing section 132 against the second end face 87 of the second rechargeable battery pack 22 and in particular against the longitudinal side of the second rechargeable battery pack 22. The second end face 87 of the first rechargeable battery pack 21 is covered by the first fixing section 131 at least partially. The second end face 87 of the second rechargeable battery pack 22 is covered by the second fixing section 132 at least partially. In an alternative embodiment of the power tool 1, it can also be provided that the second end faces 87, 87 of the two rechargeable battery packs 21, 22 are completely covered by the fixing sections 131, 132.
[0340] As shown in FIG. A19, the fixing device 130 comprises a middle section 133. The first fixing section 131 and the second fixing section 132 are connected to one another via the middle section 133. In the present embodiment, the fixing device 130 extends in the longitudinal direction 85, 85 of the rechargeable battery packs 21, 22 merely in the region of the rechargeable battery pack 21, 22 themselves without contacting the fastening section 14 in the process. The rechargeable battery packs 21, 22 project with a free end out of the fastening section 14. The fixing device 130 extends in the longitudinal direction 85, 85 of the rechargeable battery packs 21, 22 in particular over at least 50%, preferably over 70%, in particular over 85% of the free end of the rechargeable battery packs 21, 22. It can also be provided that the fixing device 130 extends up to the fastening section 14 and contacts the latter.
[0341] As shown in FIG. A19, the fixing device 130 is held on the housing 2 via a positioning unit 134, presently designed as a tether. The positioning unit 134 is fastened to the fastener 11. The positioning unit 134 can also comprise an eyelet, in particular an elastic eyelet, which is suspended from the fastener 11 and to which the tether is fastened. The tether is shown in FIG. A19 schematically, in dashed lines. As shown in FIGS. A19, A20 and A21, a retaining guide 135 is formed on the middle section 133. The retaining guide 135 is formed from a first opening 136, through which the tether is threaded from the receiving space to the outside. The tether then runs in a first channel 137 assigned to the retaining guide 135 along a longitudinal side of the fixing device 130. Provided in the channel 137 is a second opening 138, into which the tether is threaded and runs onto the other longitudinal side of the fixing device 130. On the other longitudinal side of the fixing device 130, a first opening 136, a channel 137 and a second opening 138 are likewise provided mirror-symmetrically, through which the tether runs back again.
[0342] The tether is preferably elastic. To release the fixing device 130 from the rechargeable battery packs 21, 22, it should be pulled away from the rechargeable battery packs 21, 22 in the longitudinal direction 85, 85 of the rechargeable battery packs 21, 22. Subsequently, the fixing device 130 can hang loosely from the fastener 11. The rechargeable battery packs 21, 22 can now be released from the fastening section 14 and charged or replaced with other rechargeable battery packs 21, 22. Once the rechargeable battery packs 21, 22 have been fastened to fastening section 14 again, the fixing device 130 can be put back on the second end faces 87, 87 of the rechargeable battery packs 21, 22 by stretching the tether.
[0343] FIG. A22 shows an alternative design of the fixing device 130. This has, alternatively to the retaining guide 135, a first opening 136 on at least two longitudinal sides, through which opening the tether can be threaded.
[0344] It can also be provided in one alternative embodiment that the fixing device 130 extends as far as the fastening section 14 and partially overlaps the latter. The overlapping of the fastening section 13 by the fixing device 130 can be designed in such a way that a clamping effect is created which holds the fixing device 130 on the fastening section 14. In such an embodiment, no positioning unit 134 is necessary, but one can also be used in addition.
[0345] The fixing device 130 is preferably made as a single part. The fixing device 130 is in particular formed from a plastic, in particular from an elastomer. Thus, the fixing device 130 is used to protect the first rechargeable battery pack 21 and in particular the rechargeable battery pack 22 against impacts, for example if the power tool 1 falls onto the ground.
[0346] FIG. B1 shows a perspective illustration of a power tool, using the example of a chain saw. However, a hedge trimmer, a brush cutter or the like may also be provided. The power tool 1 is shown here in a parked position 2 on a parking area 3 as a reference area. However, when it is in operation, it can also be brought into various other positions.
[0347] The power tool 1 comprises a tool 12, which here is embodied as a saw chain rotating around a guide bar 11, and which is driven in its rotary movement during operation by a drive motor 10, which is only indicated here. The drive motor 10 can be a combustion engine and is in the shown exemplary embodiment an electric motor for cordless operation. Alternatively, however, a mains voltage-powered operation is also an option.
[0348] The power tool 1 comprises a housing 21, onto the rear end of which that faces the user a handle 4 is molded as part of the housing 21. A grip tube 5 is also attached in the direction of the tool 12 towards the front. Between the rear handle 4 and the front grip tube 5, a battery recess 9 for a spare battery (not shown) for supplying energy to the power tool 1 is molded in the housing 21. Located in front of the grip tube 5 in the direction of the tool 12 is a hand hoop guard 8. A loudspeaker 45 of an optional noise generator for adjusting the operating noise is attached in the region of the hand hoop guard 8.
[0349] The power tool 1 is provided on its rear handle 4 with a first operating element 6 for controlling the drive motor 10. The first operating element 6 serves to control the power of the drive motor 10, wherein a power setting between off and full load can be set steplessly via corresponding control electronics. Alternatively, however, a simple on/off switch may also be expedient. A second operating element 7, likewise attached to the handle 4, serves as a locking element for the first operating element 6. In the unactuated state of the second operating element 7, the first operating element 6 cannot be depressed, so that the drive motor 10 is prevented from being accidentally powered. Only in the actively actuated state of the second operating element 6 can the first operating element 6 be depressed, which causes the drive motor 10 to start up and drive the tool 12.
[0350] FIG. B2 shows a perspective interior view of the region of the handle 4 according to FIG. B1, wherein to illustrate the inner mechanical structural design, a half-shall, facing the viewer, of the handle 4 has been taken off and is not illustrated. For further clarification, FIG. B3 shows the arrangement according to FIG. B2 in a longitudinal sectional illustration, wherein the following embodiments relate to viewing FIG. B2 and 3 in combination.
[0351] The first operating element 6 is pivotably mounted on a bearing journal with a pivot axis 16 and is pressed by means of a return spring 20 into the unactuated position 14 illustrated here. The pivot axis 16 of the first operating element 6 lies transverse to the longitudinal direction of the power tool 1 according to FIG. B1. An operating section of the first operating element 6 that is accessible to the user projects downwards out of the handle 4 formed as part of the housing 21. The first operating element 6 is provided with an operating element opening 40 in its lower region in its weight direction, which allows dirt to exit from the region of the second operating element 7.
[0352] The second operating element 7 has a bearing shaft 35 that extends from a first, front bearing journal 23 to a second, rear bearing journal 24. The two bearing journals 23, 24 are pivotably mounted in corresponding bearing openings of the housing 21 and thereby define a pivot axis 17 of the second operating element 7. The pivot axis 17 of the second operating element 7 runs approximately parallel to the longitudinal axis of the power tool 1 according to FIG. B1. FIG. B11 shows a front view of the arrangement described herein. It is apparent from looking at FIG. B2, 3 and 11 in combination that the pivot axis 16 of the first operating element 6 and the pivot axis 17 of the second operating element 7 are inclined towards one another and here in the preferred exemplary embodiment run perpendicular to one another.
[0353] The second operating element 7 has at least one operating section 26, here two operating sections 26 auf, which are provided for the operator to actuate the second operating element 7. The operating sections 26 have a connecting region 27, by means of which they are preferably connected in one piece to the other sections of the second operating element 7. The housing 21 is provided with an opening 22 in the region of the handle 4. The two operating sections 26 project at this connecting region 27 through the opening 22 to the outer face of the housing 21.
[0354] The second operating element 7 is shown here in an unactuated position 18. The arrangement comprises a spring 13, which interacts with an actuating contour 30 of the second operating element and thereby holds the second operating element 7 in this unactuated position 18. In particular, it can be seen in FIG. B3 that the spring 13 has a tensioning section 28, which is securely attached to the housing. This is adjoined by a middle region 41 of the spring 13. On its opposite, rear end, the spring 13 is provided with an actuating section 29, which rests on the actuating contour 30 and thereby exerts the desired holding and return effect on the second operating element 7.
[0355] Lastly, it can still be seen that the second operating element 7 comprises a cover section 32 which partially encircles the pivot axis 17 in the form of a cylinder section. The operating sections 26 are integrally connected to or molded on this cover section 32 via its connecting regions 27. The opening 22 is at least partially covered on the inner face of the housing 21 by the cover section 32. It is apparent from looking at FIG. B2 and 3 in combination with FIG. B5 and 9 that the opening 22 is completely covered in all positions of the second operating element 7, both in the circumferential direction and in the direction of the pivot axis 17.
[0356] FIG. B4 and 5 show the arrangement according to FIG. B2 and 3 in each case in a side view with a viewing direction parallel to the pivot axis 16 of the first operating element 6. It can be seen that in this viewing direction, the first operating element 6 is arranged below the bearing journal 23, whereas the spring 13 is located thereabove. In other words, the first operating element 6 and the spring 13 are arranged in the mentioned viewing direction on opposite sides of the bearing journal 23 of the second operating element 7.
[0357] In the direction of the pivot axis 17 of the second operating element 7, the connecting region 27 of the operating sections 26 extends along an operating section area 38 of the power tool 1. Perpendicular to the pivot axis 17 of the second operating element 7 lie two planes 36, 37, between which the connecting region 27 of the operating sections 26 lie. In other words, the connecting regions 27 of the operating sections 26 extend from the first plane 36, which is perpendicular to the pivot axis 17, to the second plane 37, which is likewise perpendicular to the pivot axis 17, and they do not project beyond the mentioned planes 36, 37. The planes 36, 37 furthermore enclose the operating section area 38 of the power tool 1 (FIG. B1).
[0358] Furthermore, it can be seen from looking at FIG. B4 and 5 in combination that, in relation to the direction of the pivot axis 17 of the second operating element 7, the tensioning section 28 and the actuating section 29 of the spring 13 extend at least partially on opposite sides of the operating section area 38. In the preferred exemplary embodiment shown, the tensioning section 28 and the actuating section 29 are arranged completely outside the operating section area 38 and on opposite sides thereof.
[0359] The spring 13 extends between the cover section 32 and the pivot axis 17. In the process, the cover section 32 covers the central region 41 of the spring 13 towards the outer face of the housing 21. In a combined view with FIG. B10, it can still be seen that the actuating contour 30 of the second operating element 7 and the cover section 32 delimit an opening 42 through which the spring 13 projects. In other words, the spring 13 plunges through the second operating element 7 in the longitudinal direction.
[0360] FIG. B6 to 9 show the same arrangement in same views as FIG. B2 to 5, with the difference that the second operating element 7, starting from the unactuated position 18 according to FIG. B2, is now pivoted corresponding to an arrow 44 about the pivot axis 17 and into an actuated position 19 (FIG. B6). The user does this by pressing a finger on one of the two operating sections 26. In the actuated position 19 (FIG. B6) of the second operating element 7, the first operating element 6, starting from its unactuated position 14, can be pivoted or pressed about its pivot axis 16 counter to the force of the return spring 20 and into an actuated position 15. Firstly, it is apparent from FIG. B2 to 5 that the second operating element 7, in its shown unactuated position 18 shown there, blocks a movement of the first operating element 6 in the direction of the actuated position 15 (FIG. B6). For this purpose, the second operating element 7 is provided with a downwardly projecting extension 25 that interacts with a locking section 31 of the first operating element 6. In the actuated position 19 according to FIG. B6 to 9, the extension 25 is, however, 7 pivoted away so far to the side owing to the pivoting movement of the second operating element that it no longer overlaps the locking section 31 of the first operating element 6. The first operating element 6 can be depressed into the actuated position 15, without that the locking section 31 colliding with the extension 25.
[0361] Furthermore, it can be seen that the spring 13 acting on the second operating element 7 is designed as a leaf spring. It is apparent from a combined view of FIG. B5 and 9 that the leaf spring has a midplane 33 with which it emerges from the housing restraint in the region of its tensioning section 28. In this case, the midplane 33 is designed to have an incline relative to the pivot axis 17 of the second operating element 7 in such a way that the midplane 33 makes an angle with the pivot axis 17. The angle is preferentially at least 10 and is at least 15 in the shown exemplary embodiment. Starting from the tensioning section 28, the leaf spring runs along a bending line due to its pre-tension, so that in the region of the longitudinally opposite end, in the bent-up state according to FIG. B9, it runs approximately parallel to and at a small distance from the bearing shaft 35.
[0362] It is apparent from looking in particular at FIG. B6 and 7 in combination that the actuating section 29 of the spring 13 has one contact section 39, here two laterally mutually opposite contact sections 39, in the contact region with the actuating contour 30. The contact sections 39 are bent away from the actuating contour 30 in the circumferential direction relative to the pivot axis 17. Moreover, the actuating section 29 with its contact section 39 is arranged in the direction of the pivot axis 17 outside the cover sections 32, so that the bent-up contact sections cannot collide with the cover section 29 even when in the raised state according to FIG. B9.
[0363] From looking at FIG. B2 and 6 in combination, it is apparent that the actuating contour 30 of the second operating element 7 has at least one convexly curved section 43 against which the spring 13 rests with its actuating section 29 in particular in the actuated position 19 (FIG. B6). In the shown preferred exemplary embodiment, comprises the actuating contour 30 comprises a respective convexly curved section 43 on either side of the pivot axis 17. The two convexly curved sections 43 are designed to be mirror-symmetrical to each other. In the unactuated position 18 of the second operating element 7 according to FIG. B2, the spring 13 with its actuating section 29 lies in the center between and on both convexly curved sections 43. The arrangement of the convexly curved sections 43 on both sides allows the second operating element 7 to be actuated not just in the direction of the arrows 44 (FIG. B6) in order to reach an actuated position 19. Rather, a pivoting movement of the second operating element 7 counter to the direction of the arrow 44 is also possible in order to reach an actuated position 19. Both actuated positions have the effect that the blocking of the first operating element 6 by means of the extension 25 is removed.
[0364] Furthermore, it can be seen in FIG. B6 that on pivoting the second operating element 7 into the respective actuated position 19, the actuating section 29 of the spring 13 slides with one of its bent contact sections 39 along the associated, convexly curved section 43, to allow a free pivoting movement. By comparing FIG. B5 and 9 it becomes apparent that the actuating section 29 of the spring 13 sliding on the actuating contour 30 is raised counter to its spring force, thereby increasing the acting spring force. The convex shape of the curved sections 43 causes an only initially high force increase, which then increases only slightly as the deflection progresses. Since, moreover, in the actuated position 19 the actuating section 29 presses eccentrically to the pivot axis 17 on the curved section 43 (FIG. B6), a self-aligning torque is created, which automatically turns the second operating element 7 from the actuated position 19 (FIG. B6) back into the unactuated position 18 (FIG. B2).
[0365] It can be seen from the rear view according to FIG. B10 that one of the two operating sections 26 in the unactuated position 18 (FIG. B2) protrudes straight up at a right angle to the associated tangent of the cover section 32. The further operating section 26 projects laterally at an angle and is ergonomically offset. In this case, however, it makes an angle of at least 30 with the associated tangent of the cover section 32 in the connecting region 27. In the exemplary embodiment shown, this angle is equal to 90, just as in the case of the vertical operating section 26. It is also apparent from the same view that the cover section 32 extends over an angle range of at least 120, here of slightly more than 180, arcuately about the pivot axis 17.
[0366] FIG. B12 shows a perspective view of a variant of the grip region according to FIG. B2 to 11, in which the opening 22 in the housing 21 is enlarged towards the right side to make space for an optional third operating section 26 of the second operating element 7. This optional operating section 26, only indicated here schematically in dashed lines, can be configured for example mirror-symmetrically to the opposite-lying offset operating section 26, in order to make it easier to access.
