Abstract: The invention relates to a hand machine tool (2), particularly a percussion drill and/or percussion hammer, comprising a housing (4) having two parallel appendages (20, 22), a hollow, U-shaped, rounded handle (10) with a yoke (24) and two parallel legs (26, 28), said handle being movably supported on springs in relation to the housing (4) for the purpose of damping vibration. The appendages (20, 22) of the housing (4) extend into both hollow legs (26, 28) of the rounded handle (10). The invention also comprises two coupling elements (34, 36) situated in the hollow yoke (24) of the rounded handle (10) which serve to synchronize the movements of both legs (26, 28). The external end faces of the coupling elements (34, 36) are flexibly connected to the appendages (20, 22). The coupling elements (34, 36) are connected on the other end faces thereof to the rounded handle (10), and cross each other, and are flexibly connected to each other at the crossing point.

Abstract: The present invention is directed to a hand-held power tool handle device with a vibration-shielding unit (10) and a guide device (12) for guiding a motion (26) of a handle element (16) which is movably supported relative to a hand-held power tool body (14). It is provided that the motion (26) is at least substantially along a straight line.

Abstract: A hand-operated power tool has a housing with a drive mechanism for driving a tool, a tool receptacle for receiving a tool, a handle assembly for grasping and handling located in a rear region which is remote from the tool receptacle and engaging the housing, wherein the handle assembly is vibration-damped with respect to the housing with components contained in the housing, at least and substantially in an axial direction.

Abstract: A hand-operated power tool (10), in particular a drill hammer and/or jackhammer, has a housing (11) which has a drive mechanism for driving a tool (12) that is receivable in a tool receptacle (13) and, in the rear region (14), remote from the tool receptacle (13), has a handle assembly (20) for grasping and handling that engages the housing (11). The handle assembly (20) is vibration-damped with respect to the housing (11), with the components contained in it, at least and substantially in the axial direction, by means of a vibration-damping device (FIG. 1).

Abstract: A hand power tool has at least one safety coupling arranged in a drive train, the safety coupling having at least two coupling elements for transmitting a torque around a rotary axis, at least one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, a guiding element, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage, and the arresting element unlatching and keeping in contact with a surface toward which the arresting element is urged by the spring in response to exceeding of predetermined torque.

Abstract: A hand power tool has at least one safety coupling arranged in a drive train and having at least two coupling elements for transmitting a torque around a rotary axis, at lest one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, so that the coupling elements are at least disconnected in response to exceeding of predetermined torque, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, and the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage.
