Abstract: A deflecting roller for link chains, for example, round link chains or profiled steel chains, presents, on the periphery, chain pockets for lying chain links. Furthermore, chain pockets for standing chain links are provided. The chain pockets for the standing chain links are separated from each other by teeth.

The spiral surface can be effectively reconfigured with respect to a portion of the cable fitting therearound.

Abstract: An automobile window shade system comprises a frame (20) formed of hollow horizontal elements (20a through 20d) and hollow vertical elements (22a through 22f) interconnected by T-shaped connectors (24a through 24f). The frame is installed inside the automobile and contains a beaded cord (128) with beads or expansions (130) rigidly attached to the cord. Two adjacent shades (142 and 144) are made of a light-impermeable flexible material and are attached to a yoke. An embodiment with a beaded thread (128) and an expandable spring-loaded C-shaped portion of the yoke makes it possible to shield and unshield windows selectively by fixing the yoke and pulling the beaded cord through the spring-loaded C-shaped hole of the yoke. As a result, the shades are shifted to a new initial position and then moved from this new position.

Abstract: A universal or ball pivot-link chain is guided in two substantially tubular-shaped guide channels and is deflected or turned between such guide channels by means of a driven chain or sprocket wheel. At its circumference the chain wheel possesses a profiled structure formed by recesses or depressions which substantially correspond to the profile or outer contour of the universal link chain. The guide channels extend to the circumference of the chain wheel and form in conjunction therewith a respective transfer or transition region. At each such transfer region the chain wheel protrudes by an amount, essentially corresponding to the depth of the recesses, into the interior of the related guide channel. At such transfer or transition regions the chain links are guided both by the chain wheel and the guide channels. Consequently, there is ensured for a gentle and jerk-free transfer of the chain links from the chain or sprocket wheel to the guide channels and vice versa.
