A detachable blocking device, in particular on a clamping tool, having a blocking element, which blocks the displacement capability of a rod in at least one detachment direction in a blocking position, and a detachment member, which displaces the blocking element into a release position when moved from a default position into a detachment position, in which release position the rod can be displaced at least in the detachment direction. A brake element, in a braking position, acts on the rod so that the rod can only be displaced after neutralization of a braking force acting against the displacement direction of the rod, which braking force does not have to be neutralized in a sliding position of the brake element. The brake element has a brake lever and/or can be brought into its sliding position by pivoting an arm of the detachment member having a detachment lever.

Detachable blocking device, in particular on a clamping tool

A device for connecting two clamps, each of which has a rail, including a housing that has two insertion openings, which point away from each other and each of which has an adjoining insertion channel, for inserting a respective rail. The device also includes at least one adapter piece which can be inserted into one of the insertion openings and which reduces the free opening cross section of the insertion channel in order to insert a rail with a different cross-sectional area. The adapter piece has a lining which adjoins a collar. The lining rests against the wall of the insertion channel at least in some regions and forms an insertion channel with a reduced cross section in the inserted state, and the collar rests on an end face of the housing.

The patent application relates to a saw horse having at least two stand elements, each stand element () having a base () and two vertical braces () which in each case leave an interspace () between one another for accommodating wood () to be sawed or the like, and which project upwardly from the base (). One vertical brace () of one stand element () is connected to a vertical brace () of the other stand element () via a connecting element () in such a way that the interspaces () of the two stand elements () are aligned with one another in an operating position in which the connecting elements () extend parallel to one another. In order to achieve a refinement that is advantageous for use, it is proposed that the connecting elements () are pivotably secured to the vertical braces () so that the saw horse may be folded up in a parallelogram-like manner from its operating position, in which the connecting elements () are spaced at a maximum distance from one another, into a storage position in which the connecting elements () are spaced at a minimum distance from one another.

Saw horse

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.
