[0022] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. Fig. 1 shows a schematic perspective view of an embodiment of a user-portable processing system according to the invention with a user-portable battery pack receiving device according to the invention, Fig. 2 a detail of the battery pack holder according to Fig. 1 in a schematic front view, Fig. 3 a detail of the battery pack holder according to the Fig. 1 and Fig. 2 in a schematic rear view, Fig. 4 a detail of the battery pack holder according to the Fig. 1 to 3 in a schematic plan view, Fig. 5 shows a detail of another embodiment of a user-portable battery pack receiving device according to the invention in a schematic perspective view, and Fig. 6 shows a schematic side view of another embodiment of a battery pack receiving device according to the invention.

[0023] A user-portable battery pack receiving device 1 according to the invention is provided for exchangeably receiving an electrical battery pack 30 and for electrically connecting the received battery pack 30 to a hand-held battery-operated electrical processing device 50. The battery pack receiving device 1 has a battery pocket 2 for exchangeably receiving the battery pack 30. The battery pack receiving device 1 has a user-graspable handle element 3. The battery pack receiving device 1 has a carrier 4 for fastening the handle element 3 to the battery pocket 2. The carrier 4 can comprise or be a metallic sheet metal part. In particular, the present description of preferred embodiments applies to all Fig. 1 to 6, unless otherwise stated and / or contextually excluded.

[0024] The battery pack receiving device 1 has, for example, an overload element 5 which, according to the Fig. 1 to 5 is designed for hooking a user-portable or user-worn snap hook 60. The overload element 5 is arranged on the handle element 3 and coupled to the carrier 4 in a force-transmitting manner. The overload element 5 is designed here as an overload ring.

[0025] The battery pack receiving device 1 has a flexible connecting device 6. The connecting device 6 serves, on the one hand, to electrically connect the received battery pack 30 to the processing device 50 and, on the other hand, to force-transmittingly connect the carrier 4 to the processing device 50.

[0026] In this case, the carrier 4 has a first carrier end 8 and a second carrier end 9 opposite the first carrier end 8. The carrier ends 8, 9 can be opposite one another along a receiving direction A of the battery pack receiving device 1. In the receiving direction A, the battery pack 30 can be received by the battery pocket 2. The first carrier end 8 is attached to a handle back 10 of the handle element 3. The second carrier end 9 is attached to a pocket back 11 of the battery pocket 2.

[0027] For example, the overload element 5 is designed to transmit a force, in particular tensile force, introduced into the overload element 5 by means of the carrier 4. The force introduced into the overload element 5 on the carrier side can be transmitted by means of the overload element 5, for example as shown in Fig. 1 to 5 directly or as in Fig. 6 indirectly, to the hooked snap hook 60. In the hooked state, the force can be transmitted, for example, along a direction of gravity to the hooked snap hook 60. The overload element 50 is designed to automatically interrupt the transmission of the force, for example irreversibly, if the force exceeds a predetermined self-opening value of the overload element 5.

[0028] For example, the battery pack receiving device 1 has a connecting element 7, by means of which the handle element 3 is fastened to the carrier 4. The connecting element 7 projects through the overload element 5, for example between the handle element 3 and the carrier 4. The overload element 5 can have an inner diameter that is, on the one hand, larger than an outer diameter of the connecting element 7 and, on the other hand, smaller than a width of the handle element 3. For example, the overload element 5 can be pivoted by means of the handle element 3, in particular together with the handle element 3, relative to the snap hook 60 to be hooked in, in order to suspend and / or hook the overload element 5 onto the snap hook 60 to be hooked in. For example, the overload element 5 can be pivoted by means of the handle element 3 about a pivot axis S running perpendicular to the receiving device A of the receiving pocket 2.

[0029] For example, the battery pack receiving device 1 has a gripping space 12 for the user to grip the gripping element 3. The gripping element 3 has, for example, a gripping recess 13. The battery pocket 2 has a receiving side 14, on which, in the present case, a receiving opening 26 of the battery pocket 2 is provided. The receiving side 14 and the gripping recess 13 can partially delimit the gripping space 12, as is the case here. In the present case, the gripping element 3 is designed as a one-hand gripping element, which is in particular anatomically adapted to a single user hand. The one-hand gripping element is configured such that it can be gripped by the single user hand. The one-hand gripping element can have a four-finger gripping recess, as is the case here, which is designed to at least partially accommodate an index finger, a middle finger, a ring finger, and a little finger of the single user hand gripping the gripping element 3.

[0030] The battery pocket 2 has, for example, a pocket body 25, which has the receiving opening 26 provided on the receiving side 14 of the battery pocket 2. Furthermore, the battery pocket 2 in this case has a closure flap 27 for closing the receiving opening 26. The closure flap 27 can be folded over to expose the receiving opening 26. The closure flap 27 can have a viewing window 28, in particular a recessed one, for a display device 31 of the received battery pack 30 when the receiving opening 26 is closed by means of the closure flap 27. The display device 31 can serve, for example, to display a current charge level of the battery pack 30. The battery pocket 2 can have a user-operable clip device 29, by means of which the closure flap 27 can be releasably fastened to the pocket body 25 in a state in which the receiving opening 26 is closed.

[0031] The connecting device 6 comprises, for example, an electrical conduction device 15 and a strap 16. The electrical conduction device 15 serves to electrically connect the accommodated battery pack 30 to the processing device 50. The strap 16, in contrast, serves to force-transmit the connection of the carrier 4 to the processing device 50. In this respect, the electrical conduction device 15 and the strap 16 can each fulfill one of the functions of the flexible connecting device 6. In this case, the electrical conduction device 15 is connected at each end to a bottom side 17 of the battery pocket 2 and to a top side 18 of an electrical plug 19 of the connecting device 6, which is remote from the battery pocket. The electrical conduction device 15 thus ends, for example, at the bottom side 17 on the one hand and at the top side 18 on the other.The strap 16 is connected, for example, to the carrier 4 at a distance from the underside 17, in this case in the area of ​​the rear side 11 of the battery pocket 2, and can be connected or is connected to the processing device 50 at a distance from the top side 18 of the electrical plug 19. The strap 16 can therefore end, on the one hand, at a distance from the underside 17 on the carrier 4 and, on the other hand, at a distance from the top side 18 on the processing device 50. The connecting device 6 can have at least one Y-shaped connecting end region 20 with a first Y-end branch 21 and with a second Y-end branch 22. In the present case, both connecting end regions 20 are Y-shaped. The first Y-end branch 21 has an end region 23 of the electrical conduction device 15. The second Y-end branch 22 has, in this case exclusively, an end region 24 of the strap 16.

[0032] Alternatively or in addition to the overload element 5, the carrier 4 can have a predetermined breaking point 33, in this case tapered, as shown in the illustration of the Fig. 5 is indicated by dashed lines. The predetermined breaking point 33 is arranged, for example, between the battery pocket 2 and the overload element 5, so that the force introduced into the carrier 4 by means of the overload element 5 is completely conducted through the predetermined breaking point 33.

[0033] As shown by the Fig. 6, the handle element 3 can be attached to the carrier 4 by means of the overload element 5. In this case, a hooking device 44, in particular in the form of a ring 55 and / or a tab, can be attached to the handle element 3, in this case opposite the overload element 5, for hooking the snap hook 60. In particular, the overload element 5 according to the example according to Fig. 6 is not used to hook the snap hook 60. In particular, the hooking device 44 does not function as an overload element 5.

[0034] It is conceivable that in the example Fig. 5 to replace the overload element 5 with the hooking device 44.

[0035] A user-portable processing system 100 according to the invention comprises the battery pack receiving device 1, for example according to the Fig. 1 to 4 or after Fig. 5 or after Fig.6. Furthermore, the processing system 100 comprises the battery pack 30, the processing device 50, and the snap hook 60. The snap hook 60 can serve for hooking the overload element 5 of the battery pack receiving device 1 and / or the hooking device 44, in particular depending on the design of the battery pack receiving device 1. The processing system 100 can also comprise a climbing harness to which the snap hook 60 is attached.
