DETAILED DESCRIPTION OF THE DRAWINGS
[0036] A preferred embodiment of a handheld machine tool 100 designed as a battery-powered handheld circular saw is depicted in FIG. 1. Battery-powered handheld circular saw 100 has an electric motor 60 for rotationally driving a tool 90 designed as a saw blade and arranged on handheld circular saw 100. Saw blade 90 is rotationally driven about a rotation axis R, which in this case points into the drawing plane. In the sawing mode as intended, saw blade 90 rotates in rotation direction D. In other words, saw blade 90 rotates in such a manner that handheld circular saw 100 in the sawing mode is pulled to a workpiece (not shown) to be sawed.
[0037] When normally operated as intended, handheld circular saw 100 is advanced in advancing direction V. The advancing direction is depicted in FIG. 1 with a horizontal arrow pointing to the right. Handheld circular saw 100 has a front handle 20 and a rear handle 30. In relation to advancing direction V of handheld circular saw 100, front handle 20 is arranged in front of rear handle 30.
[0038] In addition, handheld circular saw 100 has a receiving recess 50 for receiving a replaceable battery 200. In the embodiment shown in FIG. 1, replaceable battery 200 for operating electric motor 60 of handheld machine tool 100 designed as a handheld circular saw is completely accommodated in receiving recess 50.
[0039] According to the invention, rear handle 30 is positioned in a pivotable manner about a pivot axis S. Rear handle 30 is pivotably positioned about pivot axis S in such a manner that when rear handle 30 is in a swiveled-out state (cf. FIG. 3), receiving recess 50 is open for receiving or removing replaceable battery 200. Furthermore, rear handle 30 is pivotably positioned about pivot axis S in such a manner that when rear handle 30 is in a swiveled-in state EZ (cf. FIGS. 1 and 2), receiving or removing replaceable battery 200 into or out of receiving recess 50 is blocked.
[0040] As one can see when looking at both FIGS. 2 and 3, rear handle 30 is positioned so as to be laterally pivotable in a downward direction, i.e., rear handle 30 pivots about an imaginary arc B (indicated in FIG. 2 by an arrow), whose inflection point lies on pivot axis S.
[0041] In a preferred embodiment of FIG. 1, pivot axis S is oriented in advancing direction V of handheld circular saw 100. Pivot axis S thereby does not necessarily lie parallel to advancing direction V, but can run slightly diagonal to advancing direction Vas one can see in FIG. 1for example, with a maximum inclination angle of 20 degrees.
[0042] Pivot axis S runs exclusively above a base plane GE. Base plane GE can also be designed as a footplate plane. Base plane GE thereby corresponds to the footplate plane. Handheld machine tool 100 designed as a handheld circular saw has a base plate 10. The base plate can also be referred to as a footplate. This is particularly the case if the handheld machine tool contains a footplate. However, it is also possible that handheld machine tool 100 does not contain any base plate 10 or footplate. A base plane GE designed as a base plane is spanned by a bottom side 11, contacting a workpiece while in working mode, of a base plate 10, set to a zero-degree position and a maximum cutting depth, of handheld circular saw 100. Base plane GE spanned by bottom side 11 of base plate 10 is also illustrated in a perspective view of FIG. 2.
[0043] FIG. 1 depicts a parallel plane PE running parallel to base plane GE. The rotation axis R, pointing into the drawing plane, of tool 90 designed as a sawblade lies in this parallel plane PE. Pivot point SP lies exclusively below this parallel plane. In this way, rear handle 30 is fastened below.
[0044] FIG. 1 also depicts an axial plane AE, which is spanned by rotation axis R and a radius RA of saw blade 90. Axial plane AE forms an angle of exactly 90 degrees from a section 12, positioned in advancing direction V before rotation axis R, of base plate 10 and in rotation direction D of saw blade 90.
[0045] FIG. 1 also shows that pivot point SP lies exclusively in a chamber side, facing front handle 20, of a clearance plane ABE. Clearance plane ABE lies parallel to axial plane AE and has a clearance AS to this axial plane AE, the clearance AS being approximately twice as large, in the embodiment depicted here, as the maximum possible saw blade diameter DB of handheld circular saw 100.
[0046] Base plane GE, axial plane AE, clearance plane ABE and parallel plane PE form a spatial region in the form of a cuboid, in which pivot point SP is arranged. As one can also see in FIG. 1, pivot axis S runs through a stabilization rail 59 of handheld circular saw 100 and lies, relative to the vertical axis, below receiving recess 50. Base plate 10 is positioned on handle support 25, to which is also attached electric motor 60 and/or its housing. Pivot point SP lies at a distance from handle support 25 of front handle 20.
[0047] In reference to FIG. 2, the attachment of rear handle 30 to handheld machine tool 100 designed as a handheld circular saw is now to be explained in greater detail.
[0048] Rear handle 30 is pivotably mounted by means of a cylindrical pin 70, which runs coaxially to pivot axis S, in a pin receptacle 71 of a stabilization rail 59 of handheld circular saw 100. For this purpose, rear handle 30 has a non-depicted borehole through which cylinder pin 70 passes. FIG. 2 depicts rear handle 30 in a swiveled-in state EZ, so that the receiving or removing of replaceable battery 200 into or out of receiving recess 50 is blocked.
[0049] FIG. 2 now shows, in relation to advancing direction V, a rear view of handheld machine tool 100 designed as a handheld circular saw from FIG. 1. From the illustration of FIG. 2, one can see that saw blade 90 is arranged left of electric motor 60. Alternatively, saw blade 90 can also be arranged to the right of electric motor 60. Base plane (GE, which is spanned by bottom side 11 of base plate 10 and already explained in relation to FIG. 1, is also drawn in the illustration of FIG. 2 for the sake of clarity. As one can also see in FIG. 2, center of gravity SP lies between base plane GE and parallel plane PE. Rotation axis R in turn lies in parallel plane PE.
[0050] Now to be further described in relation to FIG. 2 is a pivot angle SW, which is defined between swiveled-in state EZ and swiveled-out state AZ of rear handle 30. FIG. 2 indicates a pivot stop 34 and a counter-stop 36 in the region of pin receptacle 71 (cf. FIG. 1), which limit pivot angle SW. For a pivot angle of 0 degrees, rear handle 30 is in a swiveled-in state EZ, which one can see for example in FIGS. 1 and 2.
[0051] In the embodiment of FIGS. 1 to 4, a pivot angle SW limited by pivot stop 34 and counter-stop 36 is exactly 90 degrees between swiveled-in state EZ and swiveled-out state AZ of rear handle 30. Pivot angle SW is in relation to rotation axis R in this case.
[0052] FIG. 3 depicts the embodiment of FIGS. 1 and 2, wherein in FIG. 3, rear handle 30 is shown in its swiveled-out state AZ. In swiveled-out state AZ, receiving recess 50 is open for receiving or removing replaceable battery 200. In FIG. 3, replaceable battery 200 is accommodated in the receiving recess. Based on swiveled-in state EZ of rear handle 30 in FIG. 2, FIG. 3 depicts the completely swiveled-out state AZ with a pivot angle SW of 90 degrees.
[0053] Special features of handheld machine tool 100 designed as a handheld circular saw are to be explained below with reference to FIG. 4. On a mounting rail 15 of handheld circular saw 100, there is arranged a locking mechanism 40, with which rear handle 30 can be secured in its swiveled-in state EZ and, if needed, can be opened for a pivot movement. Locking mechanism 40 has a mechanical switching element 46, by means of which a pin 45 (cf. FIG. 9), which is attached to the rear handle and which can engage in a corresponding recess 48, can be locked.
[0054] As one can see in FIG. 4, recess 48 is designed for mechanical switching element 45 on a mounting rail 15, and is arranged above receiving recess 50. In swiveled-in state EZ, switching element 45 is accommodated in recess 48, which is shown in FIG. 1.
[0055] FIG. 4 depicts a safety switch 65, which is arranged inside recess 48 in the embodiment shown in FIG. 4 and which can be actuated by pin 45. Safety switch 65 is designed to interrupt the power supply to electric motor 60 when locking mechanism 40 is in an unlocked state and when in a swiveled-out state AZ. If locking mechanism 40 is locked, or rear handle 30 is swiveled-in, as is the case in FIG. 1, then safety switch 65 signals that electric motor 60 can be actuated.
[0056] As one can also see in FIG. 4, handheld circular saw 100 has a mounting rail 15. This mounting rail 15 is designed to provide rear handle 30 a contact surface, in which recess 48 is designed. If rear handle 30 is in a swiveled-in state EZ (cf. FIG. 1), rear handle 30 is secured by pin 45 against an undesired turning transversely to pivot axis S.
[0057] Below mounting rail 15, there is designed a rail guide 55, by means of which replaceable battery 200 can be pushed into and pulled out of receiving recess 50. Rail guide 55 is designed in such a manner that pulling out replaceable battery 200 is first possible after actuating a release element 58 on replaceable battery 200. For that purpose and not depicted in FIG. 4, a lug 59 actuated by release element 58 protrudes into a corresponding recess (not shown) on the bottom side of mounting rail 15.
[0058] A motor shaft 61, shown in FIG. 4, of electric motor 60 runs parallel to rotation axis R of saw blade 60. Basically, motor shaft 61 and rotation axis 60 can run coaxially in all embodiments. A parallel offset variation of 61 and rotation axis 60 is (as shown) also conceivable, if for example a gear unit is provided between motor shaft 61 and saw blade 90.
[0059] A maximum length L, in relation to advancing direction V, of handheld machine tool 100 designed as a handheld circular saw is at least twice as long as a maximum width B, perpendicular to advancing direction V, of handheld machine tool 100 designed as a handheld circular saw.
[0060] A second preferred embodiment of a battery-powered handheld circular saw 100 is shown in FIG. 5. Battery-powered handheld circular saw 100 has an electric motor 60 for rotationally driving a saw blade 90 arranged on handheld circular saw 100. Saw blade 90 is driven rotationally about a rotation axis R, which in this case points into the drawing plane. When used in sawing operations as intended, saw blade 90 rotates in rotation direction D. In other words, saw blade 90 rotates in such a manner that in a sawing operation, handheld circular saw 100 is pulled toward a workpiece (not shown) to be sawed.
[0061] When used as intended, handheld circular saw 100 is advanced in advancing direction V. The advancing direction is shown in FIG. 5 by means of a horizontal arrow pointing to the right. Handheld circular saw 100 has a front handle 20 and a rear handle 30. In relation to advancing direction V of handheld circular saw 100, front handle 20 is arranged in front of rear handle 30.
[0062] Furthermore, handheld circular saw 100 has a receiving recess 50 for accommodating a replaceable battery 200. In the embodiment shown in FIG. 1, replaceable battery 200 is fully accommodated in receiving recess 50 for operating electric motor 60 of handheld circular saw 100.
[0063] According to the invention, rear handle 30 is pivotably mounted about a pivot axis S. Rear handle 30 is pivotably mounted about pivot axis S in such a manner that when rear handle 30 is in a swiveled-out state (cf. FIG. 7), receiving recess 50 is open for receiving or removing replaceable battery 200. Furthermore, rear handle 30 is pivotably mounted about pivot axis S in such a manner that when rear handle 30 is in a swiveled-in state EZ (cf. FIGS. 5 and 6), receiving or removing replaceable battery 200 into or out of receiving recess 50 is blocked.
[0064] As one can see when viewing FIGS. 6 and 7 together, rear handle 30 is pivotably mounted in a laterally upward manner, i.e., rear handle 30 pivots about an imaginary arc (indicated in FIG. 2 by an arrow), whose inflection center point lies on pivot axis S.
[0065] In the embodiment of FIG. 5, pivot axis S is oriented in advancing direction V of handheld circular saw 100. Pivot axis S thereby does not necessarily lie parallel to advancing direction V, but canas seen in FIG. 5run slightly diagonal to advancing direction V, for example at a maximum inclination angle of 340 degrees (in the counterclockwise direction).
[0066] Pivot axis S has a center of gravity SP, which lies exclusively above a base plane GE. Base plane GE is spanned by a bottom side 11, contacting a workpiece when in operating mode, of a base plate 10, in a zero-degree setting and adjusted to the maximum cutting depth, of handheld circular saw 100. Base plane GE spanned by bottom side 11 of base plate 10 is also illustrated in the rear view of FIG. 6.
[0067] Also shown in FIG. 5 is an axial plane AE, which is spanned by rotation axis R and by a radius RA of saw blade 90. Axial plane AE forms an angle of exactly 90 degrees, extending from a section 12, located in front of rotation axis R in advancing direction V, of base plate 10 and in rotation direction D of saw blade 90.
[0068] Also shown in FIG. 5 is that center of gravity SP lies exclusively in a chamber side, facing front handle 20, of clearance plane ABE. Clearance plane ABE lies parallel to axial plane AE and has a clearance AS to this axial plane AE, the clearance AS being approximately twice as large, in the embodiment depicted here, as the maximum possible saw blade diameter DB of handheld circular saw 100.
[0069] Also shown in FIG. 5 is a handle plane HE, which is spanned by rotation axis R and a radius RA of saw blade 90. Handle plane HE forms, for example, an angle of 30 degrees, extending from a section 13, located behind rotation axis R in advancing direction V, of base plate 10 and in the opposite rotation direction D of saw blade 90. Center of gravity SP lies exclusively in a chamber side, facing front handle 20, of handle plane HE. In this way, rear handle 30 is fastened at the top. As one can also see in FIG. 5, pivot axis S runs through a mounting rail 15 of handheld circular saw 100. Pivot point 15 lies, in relation to the vertical axis, above receiving recess 50.
[0070] In the embodiment depicted here, handle plane HE, axial plane AE, clearance plane EBA and the base plane define a blunt wedge-shaped chamber region, which is devoid of center of gravity 15.
[0071] FIG. 6 now shows, in relation to advancing direction V, a rear view of handheld circular saw 100 from FIG. 5. From the illustration of FIG. 6, one can see that saw blade 90 is arranged to the left of electric motor 60. Alternatively, tool 90 designed as a saw blade can also be arranged to the right of electric motor 60, in relation to advancing direction V of handheld machine tool 100. Base plane GE, already explained in relation to FIG. 5 and which is spanned by bottom side 11 of base plate 10, is also drawn in the illustration of FIG. 6 for the sake of clarity. As one can also readily see in FIG. 2, center of gravity SP lies above base plane GE and above replaceable battery 200 accommodated in receiving recess 50.
[0072] In relation to FIG. 6, a pivot angle SW, which is defined between a swiveled-in state EZ and swiveled-out state AZ of rear handle 30, is to be described in greater detail. Indicated in FIG. 6 is a pivot stop 34 and a counter-stop 36 in the region of pin receptacle 71 (cf. FIG. 1), which limit pivot angle SW. Pivot stop 34 and counter-stop 36 are to be understood as being illustrative and may be executed by corresponding recesses or protrusions in the housing of handheld circular saw 100. Given a pivot angle of 0 degrees, rear handle 30 is in a swiveled-in state EZ, which can also be seen for example in FIG. 5.
[0073] FIG. 7 depicts the embodiment of FIGS. 5 and 6, wherein FIG. 7 shows rear handle 30 in its swiveled-out state AZ. In swiveled-out state AZ, receiving recess 50 is open for receiving or removing replaceable battery 200. In FIG. 7, replaceable battery 200 is removed from the receiving recess. Based on a swiveled-in state EZ of rear handle 30 in FIG. 6, FIG. 7 depicts the fully swiveled-out state AZ with a pivot angle of approx. 80 degrees (cf. FIG. 7, defined in the counterclockwise direction).
[0074] Special safety features of handheld circular saw 100 will be explained below in reference to FIGS. 6 to 9. These essentially correspond to the safety features described in relation to the first embodiment, wherein only their arrangement on handheld circular saw 100 is different.
[0075] On rear handle 30 of handheld circular saw 100, there is designed a locking mechanism 40, with which rear handle 30 can be secured in its swiveled-in state EZ (cf. FIG. 6) and can be opened if applicable for a pivot motion. Locking mechanism 40 has a mechanical switching element 46, by means of which a pin (cf. FIG. 9), which is affixed to rear handle 30 and which can engage in a corresponding recess 48 (cf. FIGS. 7 and 8), can be locked.
[0076] As can be seen in FIGS. 7 and 8, recess 48 for pin 45 is designed at a stabilization rail 59, which is arranged below receiving recess 50. In swiveled-in state EZ, switching element 45 is accommodated in recess 48, which is shown in FIG. 5.
[0077] FIG. 8 in turn depicts a safety switch 65, which is arranged inside recess 48 in the embodiment depicted in FIG. 8 and can be actuated by pin 45 (cf. FIG. 9). In the unlocked state of locking mechanism 40 and when in a swiveled-out state AZ, safety switch 65 is designed to interrupt the power supplied to electric motor 60. If locking mechanism 40 is locked or rear handle 30 is swiveled in, as is the case in FIG. 5, then safety switch 65 signals that electric motor 60 may be actuated.
[0078] As can also be seen in FIG. 8, handheld circular saw 100 has a stabilization rail 59. This stabilization rail 59 is designed to provide rear handle 30 with a contact surface, into which recess 48 is constructed. When rear handle 30 is in a swiveled-in state EZ (cf. FIG. 5), then rear handle 30 is secured by pin 45 against undesired turning transversely to pivot axis S.
[0079] Below a mounting rail 15 encompassed by the handheld circular saw, there is designed a rail guide 55, by means of which replaceable battery 200 can be pushed into and pulled out of receiving recess 50. Rail guide 55 is designed in such a manner that pulling out replaceable battery 200 can first occur after actuating a release element 58 on replaceable battery 200. To this end, a lug 59 also visible in FIG. 8 and actuated by release element 58 protrudes into a corresponding recess (not shown) on the bottom side of mounting rail 15.
[0080] A motor shaft 61, indicated in FIG. 7, of electric motor 60 runs parallel to rotation axis R of tool 90 designed as a saw blade. Basically, motor shaft 61 and rotation axis 60 can run coaxially in all embodiments. Even a parallel offset course of motor shaft 61 and rotation axis 60 (as shown) is conceivable, when for example a gear unit is provided between motor shaft 61 and saw blade 90. Handheld machine tool 100 designed as a handheld circular saw also has a latch mechanism 39, not shown in greater detail here, which is designed to secure rear handle 30 in depicted swiveled-out state AZ until the user overcomes a spring blocking force.
[0081] In relation to advancing direction V, maximum length L of handheld machine tool 100 designed as a handheld circular saw is at least twice as long as a maximum width B, perpendicular to advancing direction V, of handheld machine tool 100 designed as a handheld circular saw (cf. FIG. 8).
