Abstract: The invention relates to a slide plate (20) for a cam-type closure of a clamping device for releasably connecting two profiled pieces (2), comprising a coupling region (11, 28) for coupling to locking elements of the clamping device. The slide plate comprises an inner opening (23) for receiving an eccentric roll of the clamping device by which the axial displacement (30) of the slide plate (20) can be carried out. To this end, a spring region (27) is provided between the inner opening (23) for receiving an eccentric roll and the coupling region (11, 28). As a result of the resilient actuation of the eccentric roll, the user feels rising resistance, whereby haptic feedback is also provided. A closure element provided with such a slide plate additionally has a greater tolerance for profiled sections to be attached to each other.

Abstract: The invention relates to a cube-shaped profile element provided with more than six identical side surfaces, wherein preferably eight slots are arranged at an angle of 45 degrees to each other around an axis of symmetry of the side surface and wherein a central boring is provided. Through the slots behind the side surface, insertable closing elements can be inserted through the slots behind the side surface. The profile element is preferably hollow and is constructed from six identical plates that form side surfaces. All the plates are provided with eight-cornered edges, whereby the plates are connected via one edge and the other edges each form an opening at the corners of the cube-shaped profile elements. Very modular, stable construction systems are produced using these elements and cross-shaped profile strips having an acceptable appearance when connected with clamp profiles, wherein these elements each form an optically acceptable closure at the edges of the skeleton structure.

Abstract: The present invention relates to a closing bushing (7) which is intended for a clamping device (2) used for removably connecting two profiled parts (1). The clamping device (2) comprises an adjustment knob (6) in which a profiled part (1) can be locked and which can be inserted in a recess (5) formed in said profiled part (1). The closing bushing (7) is designed for the form-fitting reception of the clamping device (2) body through a recess (16), and comprises a bore in which the adjustment knob (6) can be received. The surface oriented in the introduction direction (12) of the clamping device (2) in the closing bushing (7) is larger than the corresponding surface of the adjustment knob (6). A clamping device provided with such a closing bushing (7) exhibits a greater resistance to the traction forces applied in the direction of the arrow (12). Clamping devices (2) of the above-mentioned type can also be used for profiled parts (1) made of materials different from the traditional ones, such as wooden parts.

Abstract: The profiled beam 111 is provided with a circular inner tubular part and comprises eight long slots, three of which are covered with each a clamping profile 112, 113, 114. At the supporting side, a supporting element 115 and two flat bars 116, 117 are fixed, which are provided with slots for further clamping profiles. The edges of the clamping profiles serve for the supporting of plates. A supporting surface 118 is attached laterally to the supporting element 115. The supporting element 115, which is oriented parallel to the flat bar 116, can also be mounted at the place of or additionally to this flat bar in parallel orientation to the flat bar 117, which shows the versatile applicability of the profiled beam.

Abstract: The invention concerns a clamping device for detachably connecting two profiled parts (1, 19). There can be inserted and secured in a first profiled part (1) an insert core (2) comprising an axially movable slide (7) with an end part having a projection (17, 18) which can be at least partially inserted into an opening in a second profiled part (19) in order to exert clamping pressure against a portion of the second profiled part (19), which portion partially closes the opening. The slide (7) is flat, and the insert core (2) comprises two inner grooves for axially guiding the slide (7). Rotatably guided in the insert core (2) is an eccentric (5). When the eccentric head (4) is rotated, the eccentric roller (22) presses against the inner wall (30) of a recess (12) in the slide (7) in order to move the latter into the insert core (2) into a position which enables the projection to exert the aforementioned clamping pressure.

Abstract: This clamping device is intended for releasably connecting two profiled parts (1,19). One of the profiled parts (1) is arranged so that an insert core (2) can be inserted and fixed in it. The core (2) has an axially movable bolt (7) having an end portion which comprises a projection (21) intended to be introduced in a slot of a second profiled part (19) in order to exert a force against an area of a portion of said second profiled part (19) partially covering said opening. A screw received in a threaded bush (4) engages the bolt (7) by means of a system of sliding surfaces (14,15) in order to displace the bolt axially. The bolt (7) has supporting means (27,28) for pivotally supporting holding pieces (17,17'). Said holding pieces and the interior walls of the insert core (2) have a second system of sliding surfaces (24,26) which owing to the axial movement of the bolt (7) cause a deviation of the holding pieces (17) having in its free end area said projection (21) intended to exert said force.

Abstract: A connection element for a three-dimensional framework includes a bolt (6, 7, 8, 9) which by means of a sleeve insert (3) can be fastened rotatably to one end of a rod (11), as well as a sleeve (12) into the axial through-bore of which the bolt is partly inserted, to transmit, sliding axially, a rotary movement of the sleeve (12) to the bolt. The through-bore is only in the front part of the sleeve (12) so that it can transmit a rotary movement of the sleeve (12) to the bolt. At the rear part of the sleeve (12) the through-bore has a circumference which is larger than the circumference of the form-locking front part of the through-bore. The bolt is urged out of the sleeve (12) by a spring (13). The front end part (9) of the connection element can be fastened to a junction part (10) of the three-dimensional framework.

Abstract: A connecting element for a scaffolding framework rod has a bolt 141 rotatably mounted on one end of the rod, and a guide sleeve 151 with an axial through-bore into which a section of the bolt extends. The bolt is connected to a screw insert 161 guided by a pin 171 which rides in a slot 152 of the sleeve, and a spring 172 urges the guide sleeve against a sleeve insert 130, 121 mounted on the end of the rod.
