摘要： The present invention relates to a drilling hammer comprising a hammer tube (13) that is rotationally drivable inside a housing (10), a striking tool (14) located in the hammer tube (13) and provided with a piston (15) that can driven with a reciprocating motion, and an operating mode change-over switch (35) for the “impact drilling” and “chiseling” operating modes. The hammer tube (13) is decoupled from its rotary drive when in the “impact drilling” operating mode and is secured in the housing (10) in a non-rotative manner when in the “chiseling” operating mode. To obtain a switching mechanism (37) of the operating mode change-over switch (35) having a very flat design and requiring little installation space, an actuator ring (48) is fixed on the hammer tube (13) in an axially displaceable and torsion-proof manner, the actuator ring including at least one radially projecting locking spline (51) on its outer side facing away from the hammer tube (13), the locking spline being capable of engaging in at least one axial recess (52) in the gearbox and in locking toothing (53) in the housing. Rotational motion of a control button (36) of the operating mode change-over switch (35) is converted to axial displacement of the actuator ring (48) on the hammer tube (13) by the switching mechanism (37). In addition, the operating mode change-over switch (35) can be used to activate a “drilling” operating mode, in which the striking tool (14) is decoupled on the drive side.

摘要： An electric combination hammer for use either as a drilling hammer or as a chisel hammer has a housing and a handle arranged on it. The housing has arranged on it an on-off switch having a pawl and a switch element for manually switching from drilling operation to chisel operation and vice versa. Also arranged is a catch device by which the pawl may be engaged in chisel operation and which also prevents a latched position from being engaged in drilling operation. The catch device has a catch bracket having two legs which are connected by a joint and may be brought into operative connection with a blocking element that blocks the joint in at least one pivot direction to establish the catch function. The catch device also has at least one catch element which may be brought into operative connection with another catch element that is in operative connection with the pawl.

摘要： A hand-held power tool includes a main element with a normal axis which extends perpendicularly to a tool axis and through a center of gravity. A handle is supported in the plane of motion defined by the tool axis and the normal axis such that it is movable relative to the main element. A spring unit connects the handle with the main element, and has a spring element to define a trajectory of at least one portion of the handle in the plane of motion under the influence of a load force triggered when the handle is moved out of a neutral position and approaches the stationary main element. A rotary element defines a joint-free rotation axis, about which the handle rotates in the plane of motion when a motion takes place relative to the main element.

摘要： The hand-held power tool has a vibration-damped main handle. The hand-held power tool has a device for fastening the main handle to a main element configured so that when the main element moves out of a stationary position toward the main handle the main element swivels around at least one swivel axis so that it is guided along a trajectory that extends with a slant of at least 10° relative to a flat surface, which extends through a longitudinal tool axis and which has a surface normal oriented in a normal direction perpendicular to the longitudinal tool axis. As a result vibrations with a movement component perpendicular to the longitudinal tool axis are damped as well as vibrations that induce motion of the main element in the direction of the longitudinal tool axis toward the main handle.
