摘要： The invention relates to a guiding cart for a manually guided tool, for example an abrasive cut-off machine (12), which comprises a movable frame (1) on which a first and a second locating recess (7, 8) for inserting the abrasive cut-off machine (12) are provided. A locking device (9) is assigned to the first recess (7) by means of which forces can be applied to the abrasive cut-off machine (12) in the direction of the first locating recess (7) and the second locating recess (8). In this way the abrasive cut-off machine (12) can be reliably and rapidly fixed to the guiding cart after it has been inserted into the locating recesses (7, 8). The insertion of the abrasive cut-off machine (12) is facilitated by inclined inserting elements situated in the locating recesses (7, 8).

摘要： The invention relates to a pneumatic impact mechanism for a paving breaker and/or hammer drill which is characterized by a drive piston (1) having air equalization slits (5) and an extremely reduced wall thickness of the guide sleeve (1a) thereof. This leads to a distinct reduction of the vibrations during the no-load operation of the impact mechanism, whereby advantageous characteristics of the impact mechanism with regard to wear behavior and compactness can be retained.

摘要： The invention concerns an impacting device capable of being advantageously used in an impact hammer and/or a drill for releasing by impact tools blocked in rocks. For this purpose, an impact impetus supplied by an impact piston (1) is modified by means of a impact-deflecting device comprising a sliding lever (8) and a deflecting lever (12), such that said impact is carried out in a releasing impact direction (F) opposite the normal impact direction (B) and is transmitted to a tool (4) via a slide (15) and a locking lever (6). The tool (4) is already released after a few strokes produced by the impact piston (1). Said impact device is suitable for both unilateral air springs and double air springs.

摘要： A pneumatic percussion power tool has a percussion tool housing (1), in which a drive piston (2) and a percussion piston (9) are movable in axial direction. The motion of the drive piston (2) generated by a crank mechanism is transmitted to the percussion piston (9) through a pneumatic spring in a first chamber (10), said piston cyclically striking a ram (11) or a tool. The backward motion of the percussion piston (9) rebounding from the ram (11) is supported by increasing air pressure in a third chamber (15) that is supplied with air by the drive piston (2) through a second chamber (14) and a communicating channel (13).

摘要： The invention relates to a handheld hammer drill and/or paving breaker which is at least of average weight and power class and which comprises an electric motor (23; 30), a striking tool (9) which can be actuated by the electric motor (23; 30) and a housing (2) wherein the electric motor and the striking tool are received. A handle (8) is embodied in such a way on the housing (2) that a holding position is arranged in a projection of the striking axis (6) of the striking tool (9). A rotating axis (25) of a motor shaft (26) of an electric motor is parallel to the axis of the striking axis (6), the total length (LGES) of the hammer drill and/or striking hammer (1) being small in the longitudinal direction.

摘要： The inventive handle for a drill- and/or chisel hammer has a mount (4) which can be fixed to the hammer (3). A radial grip (7) is fixed to said mount (4), the grip axis of said radial grip crossing a tool axis (5) which is defined by the position of a tool received by the hammer. A tangential grip (6) is also fixed to the mount (4). Said tangential grip (6) has a first grip section (8) whose grip axis is tangential to the tool axis (5) and a second grip section (9) whose grip axis is tangential to the tool axis (5) and essentially perpendicular to the grip axis of the first grip section (8).

摘要： The invention relates to a pneumatic piston percussive mechanism for a percussion drill and/or a drill hammer. The inventive mechanism comprises, housed in the housing (2) of the percussive mechanism, an axially reciprocating percussion piston (3). A drive piston (4) is axially reciprocated in a guide cylinder (8) of said percussion piston (3). Said guide cylinder (8) is provided on its inner face with one or more air compensation pockets (7). At least one idle opening (12) extends through the guide cylinder (8). In the percussive action, the idle opening (12) does not communicate with the ambience while in the idle mode the idle opening (12) can be displaced via an idle channel (13) that leads to the ambience and thus connects a cavity (6) that receives a pneumatic piston with the ambience by way of the idle opening (12). The air compensation pockets (7) and the idle openings (12) allow an optimization of the piston return behavior and of the idle operation of the percussive mechanism.
