Abstract: A plug-in coupling for making electrical contact between an electric motor included in a hand-held power tool and a battery unit, which is to be accommodated by the hand-held power tool, wherein the plug-in coupling has at least one electrical contact plate to be connected to the hand-held power tool and a corresponding contact plug with two opposing resilient contact limbs, wherein the contact plug is to be arranged on the battery unit and is to be slid onto the contact plate in the sliding-on direction and withdrawn from same in the withdrawal direction, and wherein each of the resilient contact limbs has a contact region which electrically contacts a respective side of the contact plate in the contacted state, wherein the contact regions are spaced apart from one another, in the uncontacted state, relative to a deflection direction of the resilient contact limbs.

Abstract: A percussion mechanism contains a guide tube, an exciter piston, a hammer, a pneumatic chamber for coupling the hammer to the motion of the exciter piston, a striker, and a seat for the striker. The hammer has a striking point, defined by a striking surface of the striker when the striker lies against the seat. A check valve has an outlet opening and a closing mechanism for closing the check valve against an air flow from the interior of the guide tube. The outlet opening is arranged in such a way that the outlet opening is closed by the hammer during striking operation and otherwise is open.

Abstract: A hand-held power tool has a tool socket 2, a drive 5, 6 for driving the tool socket 2, and a housing 19 in which the drive 5, 6 is accommodated. A stationary part 14 of the drive 5 is connected by means of at least one detachable clamped connection 21 to at least one element 19, whereby the element 19 is the housing 19 or another stationary part of the drive 5, 6. The clamped connection 21 has a cylindrical pocket 22 in the one stationary part 14, a bushing 27 that is made of plastic and that is inserted into the cylindrical pocket 22, and it has a screw 30 that is screwed into the bushing 27.

Abstract: A battery unit (100), which is designed for being received in a receiving recess (90) of an electrical hand-held power tool (200). The battery unit (100) includes a locking mechanism (10), which in a locking state (VZ) prevents the battery unit (100) from being pulled out of the receiving recess (90), wherein the locking mechanism (10) has an unlocking button (11) with a pressing area (13), by pressing and deflecting which the locking mechanism (10) can be brought into a release state (FZ), in which the battery unit (100) can be pulled out of the receiving recess (90) in a pulling-out direction (AR), wherein the pressing area (13) defines in the release state (FZ) and in relation to the pulling-out direction (AR) a first oblique plane (E1) in such a way that a vector component (FA) of an actuating force (FB) acting on the pressing area (13) is oriented in the pulling-out direction (AR).

Abstract: The handheld power tool has a tool socket to hold a chiseling tool on a working axis and a striking mechanism that acts upon the tool in the striking direction. The striking mechanism is arranged in a machine housing. A handle is oriented along a handle axis that is perpendicular to the working axis and that is installed on the machine housing by three suspension assemblies. The second suspension assembly has a lever arm that runs along the handle axis. The first end of the lever arm is attached to a machine housing and to a handle. A guide is attached to the other machine housing and handle. The second end of the lever arm in the guide can be forcibly deflected against a spring along a trajectory that is slanted or perpendicular to the working axis.

Abstract: A side handle (18) is provided for a handheld power tool (1). The user can grasp the side handle (18) by a grip element (19). A ring-shaped clamp is provided for clamping the side handle (18) onto the handheld power tool (1). The clamp (36) has two ends (32, 33) that can be joined. A pre-tensioned spring (39) presses the joinable ends (32, 33) against a stop (40) in order to join them under a force that acts in an effective direction (29). A release mechanism (41, 43) is held in a normal position by the force of the pre-tensioned spring (29) that acts in the effective direction (29). Against the force of the pre-tensioned spring (39) that acts in the effective direction (29), the user can deflect the release mechanism (41) into a release position in order to cancel the force that presses the joinable ends against the stop.

Abstract: A hand-held power tool has a tool socket 2 to hold a tool on a working axis 11. A pneumatic striking mechanism 6 has an exciter piston 13 that is forced to move periodically along the working axis 11 by a motor 5 and it also has a striker 14 that is coupled to the exciter piston 13 via a pneumatic chamber 18. The exciter piston 13 has a cylindrical main body 21 made of a polymer. One or more rings 24 containing copper surround the main body 21. The rings 24 protrude from the main body 21 in the radial direction.
