Abstract: A suction-cup device has a cup-shaped support body having a cup opening and a hole. A suction diaphragm is positioned in the cup opening of the cup-shaped support body. A rod extends through the hole and is connected to the suction diaphragm. A clamp has first and second arms pivotally connected together at an articulation pin, the first and second arms each having a clamping jaw at one end and an actuating section at another end. The clamping jaws are biased toward each other. The clamp has a clamping member pivotally connected to the rod by a pivot pin which extends in a direction transverse to a direction of the articulation pin. The clamping member operatively contacts the cup-shaped support body and moves the rod and actuates the suction diaphragm when the clamping member is pivoted to a suction position. The clamping member moves the rod and releases the suction diaphragm when the clamping member is pivoted to a release suction position.

Abstract: A workbench (1) has a horizontal support (3) of a work component, especially in the form of clamping jaws (31, 32) or a work top, a foot part (4) and a support body (2) interlinking the foot part (4) and the work component support (3). The support body (2) that is mounted with its end (11) facing the foot close to the edge of the horizontally extending foot part (4) is mounted with its other end (16) diagonally juxtaposed close to the edge of the work component support (3).

Abstract: Clamping or expanding pliers having a first plier arm pivotally connected to a second plier arm, and a toothed structure attached to the first plier arm. A catch member is movably connected to the second plier arm. A single bias spring biases the plier arm apart and biases the catch member to a resting position engaged with the toothed structure. Either with or without the single bias spring the catch member may include an intermediate release position allowing a separating movement of the first and second plier arms without disengaging the catch member from the toothed structure. The first and second plier arms may include a resiliently deformable plastic, with the catch member arranged so that the force required to move it to its release position is lower than the clamping force.

Abstract: A clamp has a first clamping jaw support (2) which can be displaced along a slide bar (1) and fixed thereon by applying a tilting moment. The clamping jaw support has a first clamping jaw (3), certain areas of which lie at a distance from the slide bar (1) and a second clamping jaw support (4) which is located and substantially fixed in the area of one end of the slide bar. The second clamping jaw support has a second clamping jaw (5) which is located opposite the first clamping jaw (3) and which is displaced towards the first clamping jaw (3) when the clamping jaw support is impinged upon by an eccentric pressure element (6), located at the end of the slide bar. The second clamping jaw support (4) can be pivoted about a shaft (13) which fixes it to the slide bar (1). The eccentric pressure element (6) acts upon a pressure shoulder (7) of the second clamping jaw support (4) which obliquely crosses the slide bar (1).

Abstract: A clamping tool having a first jaw connected to a pull/push rod and a fixed second jaw connected to a housing which includes a handle disposed opposite the second jaw and arranged along side a grip provided on the housing. Displacement of the handle towards the grip moves the first jaw towards the second jaw and towards a clamping position in a stepwise manner while reverse movement of the rod and jaws is blocked by a detent member. Release of the detent member is provided by a release lever. The release lever can also be utilized, in conjunction with the detent member, to move the rod and first jaw in a release direction. Movement of the rod and first jaw in the clamping direction is caused by engagement of the rod by a carry-along member. The carry-along member, in turn, is engaged by an operating arm which, in turn, is engaged by the handle. The operating arm is slidably connected to the housing thereby enabling the overall length of the operating arm and handle to be varied.
