Title
Mechanical coupling assembly, associated electrical supply 5 unit and associated charger
Prior art
The invention takes as its starting point an assembly for 10 mechanical coupling of the type according to independent claim 1, an electrical supply unit of the type according to independent claim 7 and a charger of the type according to independent claim 9.
15 US patent specification 5,208,525 describes an electrical supply device for operation of electrical equipment independently of the mains. The described electrical supply device comprises a holder fastened to the electrical apparatus for the easily detachably locked and 20 substantially completely exposed retention of a power storage unit. For the electrical conductive contact the storage unit comprises, in a countersunk bearing surface, flat, rigid contacting contacts with which corresponding counter contacting contacts are associated in the vicinity 25 of the associated counter bearing surface. The contacting contacts are proximate to a hinge axis formed by a projecting hinged cam and a cam pocket between the storage unit and the holder, so that a favourable leverage is obtained. For detachable locking, two separately, but 30 simultaneously, operable locks are provided in the vicinity of the other end of the storage unit, in which the holder is substantially embedded.
2
To charge at least one chargeable battery, which is arranged inside a housing of an electrical supply unit for electrical equipment that is to be supplied independently of the mains, the electrical supply unit is coupled to a 5 charger. It is also known from the prior art that the electrical supply unit for charging the at least one chargeable battery is disconnected from the electrical apparatus or remains connected thereto. With an electrical supply unit that is permanently integrated in the 10 electrical apparatus, the electrical apparatus can be placed on the charger where it is held by gravity.
Disclosure of the invention
15 The assembly according to the invention for mechanical coupling of an electrical supply unit for electrical equipment that is to be supplied independently of the mains, comprising a charger with the features of independent claim 1, by contrast has the advantage that in 20 the front region of the housing there is arranged at least one guide strip which for mechanical coupling with the charger engages in a corresponding receiving device arranged on the charger, wherein the combination of the at least one guide strip and receiving device acts as a swivel 25 joint or push-rear grip seat. The coupling assembly according to the invention advantageously gives the electrical apparatus coupled to the charger via the supply unit greater stability and provides it with significantly better retention on the charger while also making it easy 30 to handle. The guide strip in the front region of the housing of the supply unit centres the supply unit on the charger, wherein the guide strip, as part of the swivel joint or push-rear grip seat, receives some of the acting
3
forces. The guide strip also advantageously prevents lateral tilting of the supply unit and tilting backwards.
The electrical supply unit according to the invention for 5 electrical equipment that is to be supplied independently of the mains with the features of independent claim 8 advantageously comprises, in the front region of its housing, at least one guide strip which for mechanical coupling engages in a corresponding receiving device 10 arranged on the charger.
The charger according to the invention for an electrical supply unit with the features of independent claim 10 advantageously comprises a receiving device in which at 15 least one guide strip arranged in the front region of the electrical supply unit engages for mechanical coupling of the electrical supply unit with the charger, wherein the combination of the at least one guide strip and the receiving device acts as a swivel joint of push-rear grip 20 seat.
The measures and developments stated in the dependent claims make possible advantageous improvements to the assembly, disclosed in independent claim 1, for mechanical 25 coupling, to the electrical supply unit disclosed in claim 8 and to the charger disclosed in independent claim 10.
It is particularly advantageous that the at least one guide 30 strip and the corresponding receiving device are constructed in such a way that the swivel joint allows a swivelling movement from a starting position downwards into an end position and from the end position upwards into the
4
starting position. This allows simple handling when coupling the electrical supply unit to the charger. Prior to coupling with the charger the electrical supply unit can, as a function of the embodiment of the supply unit 5 and/or the arrangement of the electrical contacts for the electrical connection of the supply unit to the charger, be disconnected from the electrical apparatus or remain connected thereto.
10 The electrical supply unit is mechanically coupled to the charger by means of the swivel joint by insertion of the at least one guide strip of the electrical supply unit into the corresponding receiving device of the charger into the starting position and a subsequent swivelling movement of 15 the supply unit downwards into the end position. The end position is achieved for example if a housing base of the supply unit meets a surface of a receiving indentation in the charger.
20 Similar to a ski binding the electrical supply unit is advantageously held in the end position by a spring contact force. The spring applying the spring contact force is advantageously constructed so it can move to the extent that the guide strip can escape from the receiving device 25 owing to a force impulse, for example if the charger,
together with the electrical supply unit, falls and strikes a hard surface, and the housing of the supply unit can detach from the charger, so there is no damage to the housing or the charger owing to a permanent connection or 30 coupling between the supply unit and the charger. The spring contact force is advantageously produced by an electrical spring contact on which an actuating element arranged on the housing of the electrical supply unit acts.
5
Moreover, in the end position there is an electrical contact between the electrical supply unit and the charger, so the batteries of the electrical supply unit are charged.
5 The invention also relates to an assembly for mechanical coupling of an electrical supply unit for electrical equipment that is to be supplied independently of the mains, comprising a charger, wherein the electrical supply unit is arranged in a housing in which at least one battery 10 that can be charged by the charger is arranged, wherein the housing comprises at least one guide strip which for mechanical coupling with the charger engages in a corresponding receiving device arranged on the charger, wherein the combination of the at least one guide element 15 and the receiving device acts as a swivel joint or a push-rear grip seat. A guide strip is preferably provided as the guide element.
The invention also relates to an electrical supply unit for 20 electrical equipment that is to be supplied independently of the mains, comprising a housing in which at least one chargeable battery is arranged, wherein the housing comprises at least one guide element which for mechanical coupling engages in a corresponding receiving device 25 arranged on a charger, wherein the combination of at least one guide element and receiving device acts as a swivel joint or push-rear grip seat. A guide strip is preferably provided as the guide element.
30 The invention also relates to a charger for an electrical supply unit of electrical equipment that is to be supplied independently of the mains, wherein a receiving device, in which at least one guide element arranged on the electrical
6
supply unit engages for mechanical coupling of the electrical supply unit with the charger, wherein the combination of the at least one guide element and the receiving device acts as a swivel joint or push-rear grip 5 seat. A guide strip is preferably provided as the guide element.
The measures and developments stated in the dependent claims make possible advantageous improvements to the 10 assembly, disclosed in independent claim 13, for mechanical coupling, to the electrical supply unit disclosed in independent claim 14 and to the charger disclosed in independent claim 15.

Embodiment (s) of the invention
5
As may be seen from Fig. 1 and 2 an electrical supply unit 10, 10' , according to the invention, for electrical equipment 30 that is to be supplied independently of the mains, for mechanical coupling to a charger 20 comprises a 10 housing 11 which in the front region comprises at least one guide strip 12 and in the back region an actuating element 14, 14' .
As may also be seen from Fig. 1 the electrical supply 15 unit 10 is connected during mechanical coupling to the charger 20 to an electrical apparatus 30 which is shown only in outlines in Fig. 1, i.e. the electrical supply unit 10 can, for example, be permanently integrated in the electrical apparatus 30. The electrical supply unit 10, 10' 20 can be used for mobile, portable apparatuses, such as power tools in the form of hand-held drills, hand-held screwdrivers, garden equipment, etc.
Fig. 2 shows a supply unit 10' disconnected from the 25 electrical apparatus 30 with two guide strips 12 arranged in the front region, an actuating element 14', arranged in the back region of the supply unit 10', and electrical terminals 16 via which the supply unit 10' can be electrically contacted by the charger 20 during a charging 30 operation. For mains-independent operation the associated electrical apparatus 30 can be electrically connected to the supply unit 10' via the electrical terminals 16.
8
As may also be seen from Fig. 1, for mechanical coupling to the electrical supply unit 10, 10' a charger 20 according to the invention comprises a receiving indentation 22, at the one end of which a receiving device 22 is arranged in 5 which the at least one guide strip 12 of the electrical supply unit 10, 10' can engage for mechanical coupling. At the opposing end of the receiving device 22 there is arranged a spring 26 which is constructed for example as an electrical spring contact. The actuating element 14, 14' 10 arranged in the back region of the electrical supply unit 10, 10' acts on the spring 26, which can move in the direction of the double arrow 27, in such a way that the electrical supply unit 10, 10' is held by the spring contact force 28 of the spring 26 in an end position in the 15 charger 20.
As may also be seen from Fig. 1 the assembly 1 according to the invention for mechanical coupling comprises the at least one guide strip 12 arranged in the front region of 20 the housing 11 of the electrical supply unit 10, 10' and the corresponding receiving device 22 arranged on the charger 20. For mechanical coupling of the electrical supply unit 10, 10' with the charger 20 the guide strip 12 engages in the corresponding receiving device 22, wherein 25 the combination of the at least one guide strip 12 and the receiving device 22 acts as a swivel joint 23. A region I a in which the swivel joint 23 is located is shown in Fig. la in a detailed view, wherein in this view the guide strip 12 of the housing 11 is coupled into the receiving device 22. 30 Owing to the configuration of the guide strip 12 and the receiving device 22 the swivel joint 23 allows a swivelling movement from a starting position downwards into an end position and from the end position upwards into the
starting position. The two directions of the possible swivelling movements are shown in Fig. 1 as a double arrow 3.
5 As shown in Fig. la a simple withdrawal of the guide strip 12 from the receiving device 22 is not possible in this embodiment since a projection 25 of the receiving device 22 engages in an indentation 21 of the guide strip in the coupled state.
10
For mechanical coupling of the electrical supply unit 10, 10' with the charger 20 the at least one guide strip 12 is inserted by way of an appropriate pushing movement in the direction of arrow 2 into the corresponding receiving 15 device 22, resulting in the starting position shown in
Fig. 1. The swivelling movement predetermined by the swivel joint 23 subsequently pushes the supply unit 10, 10' downwards into the end position. The end position is attained if a housing base 13 of the supply unit 10 meets a 20 surface of the receiving indentation 24 in the charger 20. The electrical supply unit 10, 10' is held in the end position by the spring contact force 28 of the spring 26. In the end position there is electrical contact between the electrical supply unit 10, 10' and the charger 20 via the 25 spring 26, which also acts as an electrical spring contact, so the batteries (not shown) of the electrical supply unit 10, 10' can be charged.
Fig. 3 shows a schematic view of an assembly for coupling 30 an electrical supply device to a charger by means of a push-rear grip seat 29. The elements or components which correspond to elements or components of the preceding figures are provided with the same reference numerals. The
10
supply unit 10 of Fig. 1 is shown which in the front region comprises the guide strip 12 that engages in the receiving device 22 of the charger 20, wherein the guide strip 12 and the receiving device 22 are configured in such a way that 5 the guide strip 12 can only be pushed into the receiving device 22 in one direction. For this purpose the supply unit 10 or its housing 11 is placed onto a surface 31 of the charger 20 and then pushed on the plane 31 in the direction of the arrow 32 such that the guide strip 12 is 10 pushed into the receiving device 22. The receiving device 22 comprises a recess 33 with a rectangular cross-section that receives the guide strip 12, which also has a rectangular cross-section. The sizes of the recess 33 and the guide strip 12 are selected so the housing 11 and the 15 charger 20 can only be coupled by pushing the housing 11 in the direction of the arrow 32, or counter to the direction of the arrow 32 for release. It is therefore not possible in this embodiment to couple or decouple the housing 11 or supply unit 10 by a swivelling movement. Arranged at the 20 opposing end of the receiving device 22 of the charger 20 is the spring 26 which is constructed for example as an electrical spring contact. The spring 26 acts on the housing 11 of the electrical supply unit 10 such that the housing 11 is held with the guide strip 12 in the recess 33 25 and is thereby held on the charger.
Fig. 4 schematically shows the arrangement from Fig. 3 wherein the assembly is in a state that allows detachment of the housing 11 from the charger 20. For this the 30 housing 11 is pushed against the spring 26 in the direction of arrow 34, so the guide strip 12 of the housing 11 moves out of the recess 33 of the receiving device 22 and the spring 26 is moved. If the guide strip 12 is moved out of
11
the recess 33 the housing 11 can be swivelled for example in the direction of arrow 35 to remove the electrical supply unit 10 from the charger 20.
5 To insert the housing 11 in the charger 20 the housing 11 is for example firstly placed with its back region at an angle 36 onto the surface 31 of the charger 20, shown by a broken outline 37 of the housing 11, such that the spring 26 is moved. The housing 11 is then tilted 10 completely onto the surface 31 of the charger 20, so the guide strip 12 can be pushed into the recess 33 of the receiving device 22.
The push-rear grip seat 29, the swivel joint 23 and the 15 spring 26 are configured in such a way that the push-rear grip seat 29 and the swivel joint 23 can detach automatically. For this purpose the spring 26 is formed in such a way that the housing 11, when the charger, together with the housing 11, undergoes a critical force impulse, 20 for example by falling onto a hard surface, automatically detaches from the push-rear grip seat or swivel joint. For this purpose the spring contact force 28 of the spring 26 is chosen such that the spring 26 can only be moved after a critical force impulse, which can of course also be 25 deliberately applied by movement of the housing, so the housing 11 can detach from the charger, wherein the spring 2 6 can be moved to the extent that the guide strip 12 can escape from the receiving device 22. In the case of the swivel joint 23 the movable spring 26 first of 30 all allows a swivelling movement of the housing; so the guide strip 12 can escape from the receiving device 22.
