DETAILED DESCRIPTION

[0052] FIG. 1 shows a holding device 10 for arrangement on a battery pack 100 of a machine tool. First, the battery pack 100 is described.

[0053] The battery pack 100 in the present case has a housing 102 with a first housing portion 104 and a second housing portion 106. The housing portions 104, 106 are formed here as housing halves, for example. The housing portions 104, 106 are fastened to one another, for example screwed to one another. The components of the battery pack 100, for example the battery cells 107, are arranged in the interior of the housing 102 (cf. FIG. 2).

[0054] The battery pack 100 has a coupling device 110 on an upper side 108 (coupling side 108), by means of which the battery pack can be coupled to a machine tool, for example a cordless screwdriver. A ventilation channel 112 for cooling or ventilating the battery pack 100 (cf. FIG. 1) extends through the housing 102 of the battery pack 100. The flow channel 112 has an inlet 114 on the upper side 108 and an outlet 118 on a bottom side 116 (analogous to FIG. 4).

[0055] On one longitudinal side 120, the battery pack 100 has a button 122 for actuating a locking element 124, whereby the battery pack 100 can be released from a machine tool (cf. FIG. 1). The battery pack 100 can also have a button for actuating the locking element 124 on the second longitudinal side 126 (not shown).

[0056] The holding device 10 will be discussed below. The holding device 10 has a receptacle 12 for holding a component, in the present case a tool 14 for the machine tool (cf. FIGS. 1 and 2).

[0057] The receptacle 12 for the tool 14 extends along a longitudinal direction 16. In the example, the tool 14 is an elongated screwing tool in the form of a screw bit.

[0058] In the example, the receptacle 12 is formed as a retaining groove 13, the groove cross section (tool holding space) of which is delimited by a groove base 18 and by two lateral walls 20, 22 (which flank the groove base 18 therebetween). The retaining groove 13 is open on its outer side 24 (facing away from the groove base 18).

[0059] The groove cross section of the retaining groove 13 is configured and intended for accommodating the tool 14 (in the example, a screw bit). If the tool 14 is arranged in the retaining groove 13, it protrudes in the example partially from the groove cross section (tool 14 only partially accommodated within the groove cross section; cf. FIG. 2). In the example, the retaining groove 13 is arranged on the casing side of the battery pack 100, namely on a longitudinal side 120 of the battery pack.

[0060] The lateral walls 20, 22 can have an elastically deformable design, so that they are elastically deformed by the tool 14 when the tool 14 is inserted into the retaining groove 13 and hold the tool 14 in the retaining groove 13. The tool 14 can thus be clamped in the retaining groove 13 by the lateral walls 20, 22.

[0061] Optionally, engagement portions, snap hooks or elastomer elements can be arranged on the lateral walls, as described above (not shown).

[0062] At least one permanent magnet 30 is arranged on the groove base 18 (cf. FIG. 2). Thus, the tool 14 can be held, possibly additionally, by means of magnetic force. An individual permanent magnet 30, which extends along a longitudinal direction 16, can be arranged on the groove base 18, or a plurality of permanent magnets 30 can be provided which extend along the longitudinal direction 16 and are in some cases spaced apart from one another along the longitudinal direction 16.

[0063] In the example, the holding device 10 partially covers the battery pack 100. Thus, the holding device 10 is formed as part of a housing portion of the battery pack 100, in the example as part of the second housing portion 106.

[0064] The holding device 10 is fixedly connected to the battery pack 100. In the example, the holding device 10 is fixedly fastened to the housing 102 of the battery pack 100, specifically to the second housing portion 106.

[0065] FIGS. 3 to 5 show a holding device 10 which can be placed on a battery pack 100. The battery pack 100 can correspond to battery pack 100 as described above.

[0066] The holding device 10 for arrangement on the battery pack 100 of a machine tool has a plurality of receptacles 12 for holding a component, in the present case a tool 14 for the machine tool (cf. FIG. 5).

[0067] The holding device 10 can be placed on the battery pack 100 and is reversibly removable from the battery pack 100, wherein the holding device 10 at least partially surrounds the battery pack 100 in the mounted state (cf. FIG. 3). The holding device 10 is thus formed separately from the battery pack 100 and can be placed on or removed from the battery pack 100 as needed.

[0068] The holding device 10 has a base portion 40 and wall portions 42, 44, 46, 48 protruding from the base portion 40, namely face wall portions 42, 44 and longitudinal side wall portions 46, 48, which connect the end wall portions 42, 44 to one another (cf. FIG. 3). The battery pack 100 can thus be protected on the side 116 (bottom 116) facing away from the coupling side 108 and on the casing sides, for example the longitudinal side 120.

[0069] A recess 50, 52 is formed on each of the longitudinal wall portions 46, 48 (cf. FIGS. 3 and 5). As a result, space is made for the button 122 and, for example, also a labeling surface.

[0070] In the example, a (longitudinal) receptacle 12 for holding a component, in the present case a tool 14 (cf. FIG. 5), is formed on both longitudinal sides 54, 56 of the holding device 10, specifically on the base portion 40.

[0071] The receptacle 12 for the tool 14 extends in each case along a longitudinal direction 16. The tool 14 is an elongated screwing tool in the form of a screw bit.

[0072] In the example, the receptacle 12 is formed as a retaining groove 13, the groove cross section (tool holding space) of which is delimited by a groove base 18 and by two lateral walls 20, 22 (cf. FIGS. 3 and 5). The retaining groove 13 is open on its outer side 24 (facing away from the groove base 18). At both ends of the receptacle 12 or the retaining groove 13, an increasing portion 15, 17 is formed in each case in which the depth of the receptacle 12 or the retaining groove 13 decreases. This facilitates removal of the tool 14, as explained above.

[0073] The groove cross section of the retaining groove 13 is respectively configured and determined for receiving the tool 14 (screw bit). If the tool 14 is arranged in the retaining groove 13, it is arranged flush with the longitudinal side 54, 56 (tool 14 does not protrude or only slightly protrudes from the groove cross section, cf. FIG. 5).

[0074] The lateral walls 20, 22 can have an elastically deformable design, so that they are elastically deformed by the tool 14 when the tool 14 is inserted into the retaining groove 13 and hold the tool 14 in the retaining groove 13. The tool 14 can thus be clamped in the retaining groove 13 by the lateral walls 20, 22.

[0075] Optionally, engagement portions, snap hooks or elastomer elements can be arranged on the lateral walls 20, 22, as described above (not shown).

[0076] At least one permanent magnet 30 is arranged adjacent to the groove base 18, i.e., in the interior of the base portion 40 (cf. FIG. 5). Thus, the tool 14 can be held, possibly additionally, by means of magnetic force. A single permanent magnet 30 can be provided, which extends along a longitudinal direction 16, or a plurality of permanent magnets 30 can be provided, which extend along the longitudinal direction 16 and are in some cases spaced apart from one another along the longitudinal direction 16.

[0077] In the example, a plurality of receptacles 60 for holding a tool 14 are formed on a bottom side 58 of the holding device 10 or of the base portion 40 (cf. FIGS. 3 to 5). The receptacles 60 are each formed as a retaining groove 62. In the example, the groove cross section is dimensioned such that the tool 14 is arranged completely within the groove cross section, wherein a free space 64 remains between the tool 14 and the bottom 58 (cf. FIG. 5). In the example, the receptacles 60 or retaining grooves 62 are configured and intended to receive a tool 14 in the form of a screw bit in each case.

[0078] The receptacles 60 on the bottom 58 each extend along the longitudinal direction 16 and are arranged parallel to one another (cf. FIGS. 4 and 5). Adjacent receptacles 60 are each separated from one another by a partition wall 66.

[0079] In the example, one or more permanent magnets 68 are arranged in each second partition wall 66 (cf. FIG. 5). A (long) permanent magnet or a plurality of (shorter) permanent magnets which are spaced apart from one another along a longitudinal direction of the partition wall 66 can be arranged in a partition wall 66.

[0080] An aperture 70 for ventilating the battery pack 100 is formed on one side, in the example on the bottom 58 of the holding device 10 or in the base portion 40 (cf. FIG. 4). The aperture 70 is adapted to the cross section of a ventilation channel 112 formed in the battery pack 100.

[0081] The receptacles 60 on the bottom 58 extend along the longitudinal direction 16 only over a part 72 of the holding device 10 or of the base portion 40, wherein the aperture 70 is arranged outside this part 72. The aperture 70 is thus arranged in a part 74 of the holding device 10 or of the base portion 40 that is not provided with receptacles 60.

[0082] As described above, the holding device 10 can be formed from an elastomer, in particular from a thermoplastic elastomer. The holding device 10 can have a slip-resistant surface or a cover made of an anti-slip material, for example made of rubber. The holding device 10 can have a coating made of a soft material, in particular a coating made of rubber.

[0083] As described above, the holding device 10 can have a light source and/or a wire tracer (not shown). As described above, the holding device 10 can have a charging device for the electrical charging of mobile terminals and/or a coupling device for coupling holding means.

[0084] FIG. 6 shows an embodiment of the holding device 10, which largely corresponds to the embodiment described in FIGS. 3 to 5.

[0085] In contrast thereto, tools 14′ in the form of jigsaw blades are accommodated in the receptacles 60 on the bottom 58 of the holding device 10 or the base portion 40. The jigsaw blades can be held by magnetic force by means of the permanent magnets 68 arranged in the partition walls 66 (analogously to FIG. 5).

[0086] The receptacles 60 can each be formed as retaining grooves 62 and can be formed to receive a screwing tool. As a result, not only jigsaw blades but, for example, also screwing or drilling tools can be held as tools in the receptacles 60.

[0087] Optionally, the receptacles 60 can be adapted in cross section to the jigsaw blades. Thus, the receptacles 60 can each have the cross section of a jigsaw blade (not shown) along a part of the height of the receptacle 60 or over the entire height of the receptacle 60.
