Abstract

The invention relates to an electric device, particularly an electric hand tool, comprising: a removable power supply unit (18, 50, 66, 114, 148, 182); an accommodating area (16) for accommodating the power supply unit (18, 50, 66, 114, 148, 182) inserted in a receiving direction (20) into the accommodating area (16); a guiding means (38, 52, 74, 116, 160, 184) for guiding the power supply unit (18, 50, 66, 114, 148, 182) in the accommodating area (16), and; a locking device (22, 58, 76, 126, 164, 186) for locking the power supply unit (18, 50, 66, 114, 148, 182) in the accommodating area (16). The invention provides that the locking device (22, 58, 76, 126, 164, 186) has a detent means (44, 46, 56, 78, 122, 124, 168, 188), which is formed by a shaping of the guiding means (38, 52, 74, 116, 160, 184).

Claims

1. An electrical device, in particular an electric power tool, having a removable power supply unit (18, 50, 66, 114, 148, 182), a receiving region (16) for receiving the power supply unit (18, 50, 66, 114, 148, 182) inserted in a receiving direction (20) into the receiving region (16), a guide means (38, 52, 74, 116, 160, 184) for guiding the power supply unit (18, 50, 66, 114, 148, 182) in the receiving region (16), and a locking device (22, 58, 76, 126, 164, 186) for locking the power supply unit (18, 50, 66, 114, 148, 182) in the receiving region (16), characterized in that the locking device (22, 58, 76, 126, 164, 186) has a detent means (44, 46, 56, 78, 122, 124, 166, 188), which is formed by a structured feature of the guide means (38, 52, 74, 116, 160, 184).

2. The electrical device as defined by claim 1, characterized in that the power supply unit (66) has a housing (68), with a side face that is embodied as a guide means (74).

3. The electrical device as defined by claim 1, characterized in that the guide means (38, 52, 116) has at least one guide strip (40, 42, 54, 118, 120), with an interruption embodied as detent means (44, 46, 56, 114, 182).

4. The electrical device as defined by claim 1, characterized by a detent element (48, 98), which in the locked state is snapped into structured features on both sides of the power supply unit (18, 50).

5. The electrical device as defined by claim 4, characterized in that the detent element (48) is retained by a cohesive actuating element (24).

6. The electrical device as defined by claim 1, characterized by an actuating element (24, 94) for unlocking the power supply unit (18, 50), in which by pulling on the actuating element (24, 94) perpendicularly to the receiving direction (20), the power supply unit (18, 50) is released.

7. The electrical device as defined by one of the claim 1, characterized by an actuating element (136, 194) for unlocking the power supply unit (114, 182), which element is movable in the receiving direction (20) relative to the receiving region (16).

8. The electrical device as defined by claim 1, characterized in that the locking device (164) is provided for unlocking the power supply unit (148) by means of a pressure in the receiving direction (20), exerted on the power supply unit (148) and setting the entire power supply unit (148) in motion relative to the receiving region (16).

9. The electrical device as defined by claim 1, characterized in that the locking device (186) has a leaf spring (190), which includes a detent structured feature (192).

10. The electrical device as defined by claim 9, characterized by an actuating element (194) embodied as a slide element, in which the leaf spring (190), by a displacement of the slide element in a direction opposite the receiving direction (20), is deformed into a state that releases the power supply unit (182).

11. The electrical device as defined by claim 1, characterized in that the power supply unit (18) includes energy-storing units (36), and all the energy-storing units (36), in the locked state of the power supply unit (18), are located in the receiving region (16).
