Abstract: A clamping device for sliding roofs is provided in the region of the guidance and runner rail. An actuation lever is pivotable between locking and release positions. A clamping element is modifiable in its position by means of the actuation lever, which coacts with a countermember of the end carriage and moves the end carriage to the end of the guidance and runner rail. The clamping element is aligned with the guidance and runner rail, and is shiftable in a longitudinal direction, between a locking position retaining the end carriage, and a release position. The guide comprises in a subregion on the underside an open space such that upon shifting of the actuation lever into the release position, the clamping element is at least partly lowerable sufficiently that the end carriage can be displaced away from the end of the guidance and runner rail.

Abstract: The invention relates to a roller carriage for a sliding bow roof for a truck or truck trailer. The roof encompasses guidance and runner rails, extending on the cargo surface of the truck along the longitudinal sides of the cargo surface. Roller carriages, which comprise rollers and on which retaining bows, embodied in gantry fashion and having a roof tarpaulin mounted thereon, are displaceably guided. At least one roller carriage is equipped with a securing device for preventing inadvertent shifting of the roller carriage along the rails. The securing device encompasses a wedge element associated with a roller, which element is shiftable between a release position and a secured position. In its release position it has no contact with the roller. In its secured position a portion of the wedge element is between the roller and the corresponding guidance and runner rail.

Abstract: The invention relates to a covering frame for a tarpaulin structure, comprising a number of bows, which can be displaced along lateral longitudinal beams (4) and which each have a slide (6) at the ends thereof. Folding means (9) for force-folding a tarpaulin are provided in the vicinity of the slides (6). The invention also relates to a slide (6). A reliable and cost-effective assembly is achieved by virtue of the fact that the folding means (9) can be inserted into a guide (62a) of the slide (6) along the axis of the guide (62a). In addition, a profile of a longitudinal beam (4) for use in a covering frame is provided in order to guide a slide (6).
