- the invention is based on a handheld power tool with a rechargeable battery according to the preamble of claim 1.
- the locking connection usually has a control element or an elastically deflectable tab with molded locking pin in the longitudinal direction of the handheld machine tool on the side of the battery pack.
- the tabs are usually molded onto a housing part of the battery pack.
- the tabs are tilted around an axis against a metal spring and then, under the tension of the metal spring, engage behind a hook attached to the handheld power tool.
- the battery pack is attached to the hooks of the hooks via transmission surfaces on the locking pins Handheld machine tool supported.
- the invention is based on a hand-held power tool with a rechargeable battery which can be fixed by means of a latching connection, which has at least one latching element, which engages behind a component in the latched state and which is loaded with at least one spring element in the direction of its latched position
- the battery is supported at least partially on at least one transmission surface of the locking element on a counter surface of the component, and with at least one control element, via which the locking element can be guided out of its locking position.
- the locking element for releasing the locking connection is first displaceable and then tiltable.
- a possible linear stroke movement preferably parallel to the transfer surface, oblique transfer surfaces and counter surfaces and associated force components in the unlocking direction of the latching elements, for example by a weight of the battery, can be avoided and a connection between the battery and the hand tool can be achieved with little play.
- a self permanent unlocking is not possible.
- the transfer surface or holding surface can advantageously be oriented perpendicular to a main load direction thanks to the floating bearing, and the counter surface can be aligned parallel to the transfer surface, the main load direction being generally determined by the weight of the battery in a basic working position.
- an advantageous control element can be achieved by the lifting movement, which can be actuated by printing at different points.
- the position of a tilting axis does not have to be taken into account when actuating and a largely constant required actuating force can be achieved via the control element.
- a lifting movement running parallel to the transmission surface in principle also lifting movements running obliquely to the transmission surface are conceivable thanks to the floating bearing.
- a tilt axis of the latching element lies outside a keypad of the control element.
- the tilting axis can advantageously be chosen such that even when printing on the side of the keypad facing the tilting axis, the operating element or the latching element can be easily tilted with a small actuating force after the lifting movement.
- at least one, preferably all spring elements are advantageously molded onto the latching element and / or onto one or more housing parts of the battery. For the assembly of the locking element, however, it can be advantageous if the spring elements are molded onto the housing parts of the battery.
- the latching element and the spring element are made of plastic, as a result of which a particularly inexpensive and lightweight construction can be achieved.
- control element and the latching element being embodied in one piece, by the latching element moving at least partially, preferably completely, over at least one housing part of the battery and / or the latching element moving by at least one of the Housing part of the battery molded stop is limited.
- additional components can particularly advantageously be saved completely.
- control element can advantageously be displaced against at least one first spring element and against a second spring element when the locking connection is released tilted.
- the separate spring elements can be specifically designed for the corresponding movement. In principle, however, a spring element is also conceivable for both movements.
- the solution according to the invention can be used with all handheld power tools with a rechargeable battery that appear to be useful to the person skilled in the art, such as, for example, in a cordless screwdriver, drill, impact drill, hammer, chisel, in a cordless saw, in a cordless saw. Grinder etc.

- Fag. 2 beam lifting the hand tool machine from the battery and Fag. 10 eanen Schnatt along the L ⁇ n ⁇ e IV-IV on Fag.
- FIG. 1 shows a hand-held drilling machine with a battery 10, which is attached to the hand-held drilling machine via a latching connection 12 (FIGS. 2, 3 and 4).
- the latching connection 12 is laterally fitted on the long boring of the hand drilling machine, depending on the plastic pushbutton 26, each having two latching elements 14 in one piece.
- the latching elements 14 engage behind one each in the locked state the hook 16 attached to the hand-held power tool.
- the rechargeable battery 10 is supported on counter surfaces 24 of the hooks 16 via a transmission surface 22 per locking element 14.
- the transmission surfaces 22 are aligned perpendicular to a main load direction 28 and a counter surface 24 which is set by a weight of the battery 10 in a basic working position and parallel to the transmission surfaces 22. Forces at decontrol rushing of the latching elements 14 are avoided and an unwanted loosening of the latching connection 12 is prevented.
- the rechargeable battery 10 has a lower, first plastic housing part 34 facing away from the hand tool, which is screwed to an upper, second plastic housing part facing the hand tool.
- the pushbutton 26 Before assembly of the upper housing part 36, the pushbutton 26 is pushed in from below the lower housing half 34 and secured captively with a not-shown locking connection. During the assembly of the upper housing component 36, the radio tone of the pushbutton 26, the locking connection was canceled, and the pushbutton 26 was extended between the upper and the lower housing component 34, 36.
- the pushbutton 26 is propped up on its long length, on verta kaier downward on a side facing away from the locking element 14 at two lower bearing points 42, 44, and on the lower housing 34 antegraert sand. Pushing the push button 26 in a vertical direction upwards, it is trimmed via two upper bearing points 46, which antegraert sand above the transmission surfaces 22 on the upper housing 36. Dae upper La Gerstellen 46 each have a first bearing surface 50 in the unlocking direction, which runs parallel to bearing surfaces 48 of the lower bearing points 42, 44 and each have a second curved bearing surface 52 (FIGS. 3 and 7). The push button 26 is guided laterally over side walls 54, 56 of the upper and lower housing part 34, 36 (FIG. 2).
- the locking elements 14 are each loaded by spring elements 18, 20 in the direction of their locking position.
- a first spring element 18 is formed by a long tab formed on the lower housing part 34, which presses the pushbutton 26 with the latching element 14 in the upper region in the direction of its latching position against stops 58 formed on the upper housing half 36 (FIGS. 3 and 4).
- the first spring element 18 presses the pushbutton 26 in the vertical direction on its upper bearing surfaces 50, as a result of which a play between the pushbutton 26 and the bearing surfaces 50 is avoided and a small play between the transmission surfaces 22 and the counter surfaces 24 is achieved, namely less than 0 ,1 mm.
- the pushbutton 26 on the plain side facing away from the locking element 14 is pressed by two small spring elements 20 in the direction of its locking position against stops 60 in the lower housing part 34.
- the spring elements 20 are formed from sheets which are molded onto the lower housing part 34.
- the pushbutton 26 with the latching element 14 for releasing the latching connection 12 is first of all rectilinear, displaceable parallel to the transmission surfaces 22 and then tiltably mounted (FIGS. 5 to 8). With a first linear Stroke movement, the push button 26 is moved against the spring element 20, namely until after a stroke the push button 26 runs up on the lower side facing away from the latching element 14 at stops 40 of the lower housing part 34 (FIGS. 5 and 6).
- the stops 40 are vertically aligned outside or below a keypad 32 of the push button 26 and determine the position of a tilt axis 30 of the push button 26 and the locking element 14 with the lower bearing points 42, 44.
- the pushbutton 26 is moved laterally over the side walls 54, 56 and over the bearing surfaces 52, and the spring element 18 was preloaded further.
- a point 62 of the pushbutton 26 on the spring element 18 is selected so that the pushbutton 26 is pressed during the tilting movement by a vertical force component of the spring element 18 against the curved bearing surface 52, which has a radius of curvature which corresponds to a tilting wheel us of the pushbutton 26 the tilt axis 30 corresponds (Fig. 8).
- the pushbutton 26 is safely guided with little play when unlocking during its lifting movement and during its tilting movement, and the latching elements 14 can be extended more easily from the hooks 16 (FIGS. 9 and 10). Due to the long spring element 18, a largely constant required actuating force can be achieved via the tilting movement. The linear lifting movement and the tilting movement can be triggered by an operator on the entire keypad 32 of the pushbutton 26. If the battery is removed from the hand drill, the pushbutton 26 with the latching element 14 is returned to its starting position by the spring element 18, 20. A resetting movement which occurs is matched to an advantageous movement sequence when the battery 10 snaps into place on the hand drill.
- the hooks 16 When they engage, the hooks 16 each have an inclined surface 64 on a corresponding counter-inclined surface 66 of the latching elements 14 (FIG. 3).
- the push button 26 and the locking element 14 are deflected.
- the pushbutton 26 and the latching element 14 are guided through the prestressed spring element 18, the bearing surfaces 48, 50, 52 and the side walls 54, 56. Then the push button 26 and the detent 14 are returned to their detent position via the spring elements 18 and 20, so that the battery 10 is securely attached to the hand drill.
