  • Patent number: 9579775
    Abstract: 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.

  • Patent number: 9533399
    Abstract: 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.

  • Publication number: 20150360348
    Abstract: The invention relates to a device for connecting two clamps each having a rail (1, 2), with a housing (3) which has two insertion openings (6) directed away from one another, each having an adjoining insertion channel (7) for insertion in each case of a rail (2), and at least one adapter piece (4) which can be inserted into one of the insertion openings (6) and which reduces the free opening cross-section of the insertion channel (7) for insertion of a rail (1) with another cross-sectional surface. The adapter piece (4) has a lining (5) which adjoins a flange (10), wherein the lining (5) rests at least in some regions against the wall of the insertion channel (7) and in the inserted state forms an insertion channel (9) of reduced cross-section, wherein the flange (10) rests on an end face of the housing (3).

  • Patent number: 8528754
    Abstract: The patent application relates to a saw horse having at least two stand elements, each stand element (1) having a base (4) and two vertical braces (2) which in each case leave an interspace (5) between one another for accommodating wood (21) to be sawed or the like, and which project upwardly from the base (4). One vertical brace (2) of one stand element (1) is connected to a vertical brace (2) of the other stand element (1) via a connecting element (6) in such a way that the interspaces (5) of the two stand elements (1) are aligned with one another in an operating position in which the connecting elements (6) extend parallel to one another.

  • Patent number: 6578837
    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.

  • Patent number: 6254073
    Abstract: The invention relates to a clamping clip that can be actuated with one hand, having a drive housing comprising a hand grip and a fixed clamping jaw, with an actuating handle that can be displaced toward a rail with a second jaw by means of pivoting actuation on the hand grip, whereby the rail is blocked against back-pressure by means of a blocking element that can be released by means of thumb pressure on a release element. For better handling, it is provided that the release element forms an actuating arm that sits on a pivot axle that protrudes laterally from the housing approximately at the level of the actuating handle, the pivot axle of said arm being arranged, in relation to the direction of clamping of the rail, before the pivot axle of the handle.

  • Patent number: 6179116
    Abstract: A combination adjustable height bearing stand and roller platform assembly is provided which can be fixed at a pre-adjusted height. The combination bearing stand and roller assembly includes two pairs of legs with each pair of legs being pivotally connected together at a joint connection so that the legs can be brought from a parallel position used for storage to an angled position. The corresponding legs of the two pairs of legs are connected by cross-connectors. The legs are tubular and one leg of each pair of legs receives a height-adjustable support which can be secured at a pre-selected height by a fixing element. The top ends of the height-adjustable support are connected to fastening elements which, in turn, are pivotally connected to two carriers which support a platform assembly. Both the platform and bearing stand legs are pivotable between a collapsed and parallel storage position to an angled and horizontal position respectively using a single motion.
