A setting tool includes a piston guide ( ) displaceably arranged in the housing ( ), a bolt guide ( ) connection element ( ) for fixedly connecting the bolt guide ( ) with the piston guide ( ) for joint displacement therewith, and a locking member ( ) provided on the setting tool ( ) and having a locking position ( ) in which displacement of the bolt guide ( ) and the piston guide ( ), relative to the housing ( ), from their initial position, is prevented when the bolt guide ( ) and the piston guide ( ) are not completely connected by the connection element ( ), and a release position ( ) in which displacement of the bolt guide ( ) and the piston guide ( ) relative to the housing ( ) from their initial position to their operational position, can take place when the bolt guide ( ) and the piston guide ( ) are completely connected by the connection element ( ).

Setting tool

A setting tool includes a piston guide ( ) displaceably arranged in the tool housing ( ) and in a hollow chamber ( ) of which a piston guide ( ) is displaceable under action of a propellant from an initial position thereof to an end position thereof, a device ( ) for breaking displacement of the setting piston ( ) in its end position at an end of a setting process, and a wear recognition device ( ) associated with the setting piston braking device ( ) for automatically blocking a setting process dependent on a wear condition of the setting piston braking device.

A delivery device for a setting tool has a guide tube (,), a guide rail (,) projecting from the guide tube (,) substantially transverse thereto and having a guide channel (,) for receiving fastening elements (,), a slide (,) for transporting the fastening elements in a direction toward the guide tube (,), and a locking member (,) pivotable into an interior of the guide channel (,) for limiting the displacement of the fastening elements (,) located in the guide channel (,) in the direction opposite to the setting direction. The locking member (,) has a guide region (,) displaceable through a through-opening (,) formed in a side of the guide rail (,) extending parallel to the setting direction, and into the interior of the guide channel (,) into a locking position in which the guide region (,) formlockingly cooperates with the spaced from each other, stop edges of several fastening elements provided on stems of the elements.

A setting tool for driving-in nail-shaped fastening elements into hard constructional components and including a housing (10, 110), a guide cylinder (20, 120) displaceable in the housing (10, 110) in a direction opposite to a setting direction against a spring-biasing force, a drive piston (40, 140) axially displaceable in the guide cylinder (20, 120), and a pivotal resetting element (50, 150) having a first lever arm (51, 151) cooperating with the drive piston (40, 140) for resetting the drive piston (40, 140) to its inoperative position and a second lever arm (152) cooperating with the guide cylinder (20, 120) for displacing the first lever arm (151) in accordance with displacement of the guide cylinder (120).

A device for dispensing a flowable mass stored under pressure in a container (13) includes a handle (1) with a locking arrangement (3) at one end for coupling it to the container. The handle (1) has a manually operated trigger member (5) in a side of the handle for operating an outlet valve on the container (13). The handle (1) forms a recess (7) extending inwardly from the one end to be coupled to the container (13) toward an opposite end.

A pipe clamp is formed of a pair of semicircular clamp halves, one having a first end region (1) and the other a second end region (2). First end region (1) has a radially outwardly extending projection (3) and two guides (6, 7) located along opposite sides. Second end region (2) has a circumferentially extending radially flexural locking strip (4) with a stop face (5) directed away from a free end of the second end region (2). In the closed position, the guides (6,7) of the first end region overlap at least a part of the second end region, so that the second end region is prevented from moving radially outwardly. In moving the first and second end regions into the closed position, the projection presses the locking strip radially outwardly until the projection (3) cooperates with the stop face (5) of the locking strip (4) in the closed position.

A pipe clamp includes a wall part (1) with at least one bracket (3) located on its outside surface. At least one attachment part (2) is engageable in the bracket (3) and projects laterally outwardly from the wall part.

The container carrier (1) and housing (3) each has a central axis inclined relative to the axis of the rotatable support (2). The container carrier (1) can be driven around its axis opposite to the rotational direction of the rotatable support (2). The apparatus is balanced by an equalizing mass (3a) in the housing (3) disposed diametrically opposite the container carrier (1).

A tool for placing and securing sealing strip (11) into a joint gap (19) between structural parts (17, 18) includes a lead-in device (10) guiding the sealing strip (11) into the joint gap (19), an insertion device (8) aligning the sealing strip (11) and a contact pressure device (7) with two coextensive contact pressure faces (12, 13) for pressing the sealing strip (11) within the joint gap (19). A spacing (A) between the contact pressure faces (12, 13) transversely of their coextension is variable.

A portable hand-held tool, such as a hammer drill or chisel hammer, includes a housing having a main vibration axis and a handle displaceably secured to the housing and movable toward the housing against compression springs. The springs have an axis of compression disposed at an angle to the main vibration axis. When the handle is displaced toward the housing, the spring is compressed. At the same time, however, the increased force of the spring is compensated by the increase in the angle of the spring relative to the main vibration axis. As a result, though the spring force increases, its component acting in the main vibration axis direction is reduced, and the spring force acting in the main vibration axis direction remains constant.
