Abstract: A skid protecting device for use in combination with vehicle tires, according to which in distribution over the tire circumference there are provided holders with a plurality of gripping profiles which are arranged transverse to and in covering engagement with gripping profiles which are adapted by way of tensioning members to be connected to the outsides of the holder. The arrangement comprises at least one chain net of interengaging chain links which is located on one lateral surface of the tire. This at least one chain net has one rim portion provided with serially arranged connecting links arranged in spaced relationship to each other for connection to the holders, whereas an oppositely located other rim portion is provided with a tensioning or tightening strand extending along the last mentioned other rim portion.

Abstract: A hook, particularly an eye hook having a forked head. The hook has a hook body which forms a receiving opening for chain links which are to be suspended therein. The hook also has a closure piece detachably fastened to the hook body and projecting into the receiving opening. The closure piece is rigidly arranged on the hook body in such a way that an introduction opening is formed, the inside diameter of which corresponds to the cross sectional dimension of the chain link taken perpendicular to its annular plane.

Abstract: A wear-resistant link for tire chains, including a link body having at least one link opening between a running surface and a tire engaging surface for engagement with at least one connecting link. The surfaces defining the link opening merge with an outside area of the link body for forming an insert opening on this outside area. The wear resistant link is furthermore provided with at least one lock for the insert opening which lock includes at least one bolt or the like in engagement with the link body. The insert opening is located between the running surface and the tire engaging surface of the link body, and the lock is provided with at least one engaging surface. The arrangement is such that the respective link opening or openings in closed condition is or are defined by at least one engaging surface for engagement with the pertaining connecting link when the respective tire chain equipped with the wear resistant link is in operation.

Abstract: A latching control for a recording and/or playback apparatus. To switch on an apparatus function said control is moved in a first direction said control being lockable by moving at least part of the control in a second direction perpendicular to the first direction.

Abstract: An anti-skid tire chain, especially for dual tires in which the chain has a tread part for engaging the tread of each tire and an intermediate part between and connected to the tread parts. Each part of the chain is formed of rings and chain links connecting the rings and clamping means is provided for clamping the chain in place on a set of dual tires.

Abstract: A linkage arrangement for antiskid vehicle tire chains in which a web link in a plane perpendicular to the tire surface is pivotally linked to a substantially circular link which is parallel to the tire surface. The interengaging regions of said links are convex toward each other and vary not more than a small amount in curvature. The links are so configured within the region of pivotal interengagement thereof as to present cooperating elements of abutment means to one another which limits the relative pivotal movement thereof to about 90.degree. in the direction toward and away from the surface.

Abstract: A connecting link, especially for tire chains in which an annular link body is provided with a gap on one side for the introduction of links into the body. A closure member is provided which is receivable in the gap and which is adapted for connection to the link body. When the closure member is disposed in the gap it forms substantially a continuation of the link body so that the assembly has a smooth contour throughout the periphery thereof.
