Abstract: The invention relates to a support structure comprising a support assembly that is supported by legs. The support assembly can be pivoted around a pivoting axis (4) relative to the legs from a position of use to a rest position and can be blocked from pivoting in the position of use by a fixing member. In an advantageous improvement of such a structure, the captivation member is configured as a latch (5) that engages, in the position of use, with a wedge-type blocking surface (8) by means of a spring force, thereby forcing it against a blocking shoulder (9,9?).

Abstract: Locking or expanding pliers (1) having two plier arms (4, 5) which arc joined to each other in the manner of a scissor-type joint. The arms forming grip sections (6, 7) on one end and clamping sections (12, 13) on the other end and being able to be locked in various clamping positions, whereby the clamping results from the elastic deformation of at least one of the two plier arms (4, 5) occurring when the plier arms (4, 5) are placed in a clamping position. A spring element (F) is arranged in the active area between the clamping section and the grip section in order to achieve improved proportioning of the clamping force, whereby both grip sections (6, 7) can be disposed on top of each other and placed in another locking position (19, 20), when both clamping sections (12, 13) are maintained in a distanced position (a), in order to increase clamping power.

Abstract: The invention relates to a clamping tool com-prising a clamping jaw (5), which is releasably fixed on a rail, preferably at the end (2) thereof, and which comprises a pin (4) that passes through an opening of the rail. The clamping jaw is releasably fixed on the rail, whereby, after pulling the pin (4) out of the opening, the clamping jaw can be fixed at an opening (3) located at another position of the rail, preferably at its other end by reinserting the pin into an opening (3) located at that po-sition. A second clamping jaw (7) is displaceably arranged on said rail (1). A tightening element (8) is used to bring the second clamping jaw, according to the location of the first clamping jaw (5) on the rail (1), into a clamping position in the direction of the latter or in a direction away from the latter. The aim of the invention is to achieve a simplified changing from one fixing position to another fixing position on the rail.

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.
