A piston assembly including a piston for a cartridge discharging device for discharging a pasty compound out of a cartridge which has an inner wall, having a piston and a rear face which can be acted upon by a pressure plate secured to a push rod, a front face opposite the rear face, and a retaining element which secures the pressure plate against the rear face by a retaining protrusion which covers an edge of the pressure plate in a retaining position. The retaining protrusion is secured to the piston in a movable manner into a release position in a direction away from the push rod.

Piston assembly for a cartridge discharging device

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.

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 () 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 () that engages, in the position of use, with a wedge-type blocking surface () by means of a spring force, thereby forcing it against a blocking shoulder (').

Clamping pliers with a pistol handle

Locking or expanding pliers () having two plier arms () which arc joined to each other in the manner of a scissor-type joint. The arms forming grip sections () on one end and clamping sections () 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 () occurring when the plier arms () 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 () can be disposed on top of each other and placed in another locking position (), when both clamping sections () are maintained in a distanced position (a), in order to increase clamping power.
