- the unlocking member between the rear locking position and the front locking position remains in a ner actuated position in which it can not be moved, and only returns to an unactuated position when the Batte ⁇ riepack reaches the front locking position. Re-actuation of the unlocking member then allows disengaging the latch from engagement with the battery pack to completely remove the latch between the battery pack and the power tool for removal of the battery pack.
- the bolt and the unlocking member are formed as a unit and suitably form the two arms of a two-armed lever, one lever arm protrudes in the unactuated position via a housing of the power tool and serves as an unlocking, while his other lever arm serves as a bolt and with a Recess in the battery pack engages.
- the latch In order to maintain the lock between the rear locking position and the front locking position, the latch according to an advantageous embodiment of the invention is operable in the rear locking position to disengage it from the power tool in locking engagement with the battery pack can move in the front Verriegelungs ⁇ position where it can be actuated again to disengage it now out of engagement with the battery pack.
- a further advantageous embodiment of the invention provides for the bolt to be in the front and rear Locking position with a first degree of freedom of movement - A -
- the bolt is expediently displaceable along a guide slot of the power tool, which permits different movements as a function of the locking position.
- the latch is rotatable in the in the front and rear locking position and linearly movable between these positions in the direction of the guide.
- the guide slot is preferably designed such that the two-armed lever in the front and rear locking position engages in each case with projecting axle journals in a section of the guide slot which is oriented substantially transversely to the direction of displacement in the guide, so that the Latch in these sections by pressing the Entriegelungsor ⁇ go to rotate around different axes of rotation to disengage it from the locking engagement with the battery pack or with the Elektro ⁇ tool.
- a further preferred embodiment of the invention provides that the power tool has a spring acting on the bolt, which preferably moves it together with the battery pack into the front locking position as soon as the unlocking member has been actuated in the rear locking position.
- the spring moreover also causes the battery pack to be moved back into the front locking position if it has not been properly locked when inserted into the guide in the rear locking position, as a result of which the user is also made aware of this fact.
- FIG. 1 shows a partial cross-sectional view of a power tool and a battery pack in the locked and ready state
- FIG. 2 shows a view corresponding to FIG. 1, but after actuation of an unlocking member for removing the battery pack;
- FIG. 3 shows a view corresponding to FIG. 2, but during a movement into a locked but not ready-to-operate state
- FIG. 4 is a view corresponding to FIG. 3, showing the battery pack in a locked but not ready state;
- FIG. 5 shows a view according to FIG. 4, but after renewed actuation of the unlocking member; 6 shows a view corresponding to FIG. 5, but after a complete removal of the battery pack.
- the locking device 2 shown in the drawing serves for mutual locking of a network-independent electric tool 4, for example a hand-held hammer drill, and a battery pack 6 required for the power supply of the power tool 4.
- a network-independent electric tool for example a hand-held hammer drill
- a battery pack 6 required for the power supply of the power tool 4.
- the power tool 4 has at the free lower end of its grip part 8 a recessed guide groove 10, into which a guide rail 12 arranged at the upper end of the battery pack 6 has a cross section complementary to the cross section of the guide groove 10 can be inserted to connect the battery pack 6 with the power tool 4.
- the insertion movement of the guide rail 12 into the guide groove 10 is limited by cooperating abutment surfaces 14, 16 at the rear ends of the guide rail 12 or guide groove 10 in the insertion direction, which abut one another when the battery pack 6 is in a position shown in FIG latched rear Verriegelungspositi ⁇ on properly with the power tool 4 and an electrical connection between terminals of a Strom ⁇ memory of the battery pack 6 and a circuit of a consumer of the electric power tool 4 is made.
- the battery pack 6 In order to hold the battery pack 6 in the rear locking position shown in FIG. 1, it includes the power tool 4 in the electric power tool 4 integrated locking device 2 a two-armed lever 18, one lever arm forms a latch 20 and engages in the rear locking position in a recess 22 in the top of the guide rail 12, while its other lever arm forms an unlocking button 24 which extends over an outer surface of the handle portion 8 of Electric tool 4 protrudes and can be depressed to unlock the battery pack 6 in the rear locking position ma ⁇ nually.
- the bolt 20 is provided with a rear, substantially perpendicular to the insertion direction (arrow A in Fig. 1) aligned stop surface 28 which rests in the rear locking position against a kom ⁇ plementäre stop surface 30 of the recess 22 and a movement of the battery pack 6 against the Insertion direction blocked.
- the latch 20 is provided with a front ramp 32 which is opposite to a corresponding ramp 34 of Ausneh ⁇ tion 22. Adjacent to the upper end of the run-on slope 32 is another stop face 26 oriented transversely to the insertion direction, while a corresponding stop face 27 is located above the run-on slope 34 of the recess 22.
- the recess 22 is slightly larger than the bolt 20 so that it is limited pivotable within the recess 22.
- the lever 18 has two axle journals 36 projecting over opposite longitudinal side surfaces, which are movably mounted in a guide slot which is omitted in the grip part 8.
- the Springfieldskulis ⁇ se consists of two opposite recesses 38 in Griff ⁇ part, each one parallel to the direction of movement of the guide rail 12 in the guide groove 10 elongated middle part 40 and two at the front or rear end of the central part 40 upwards have over this protruding portions 42 and 44, which are aligned at an angle of about 80 and about 100 degrees to Einschub ⁇ direction.
