Abstract: Traction-enhancing tire chains with a lateral cable having a tension-applying connector for interconnecting the opposite ends of the lateral cable for attaching the tire chains to a tire. A clasp is attached to a pin slidably disposed in a cam slot defined in a tensioning lever attached to one end of the lateral cable. The clasp hooks about a selected anchor on the opposite end portion of the lateral cable and applies tension to the lateral cable as the lever is rotated to a tensioning position. The clasp slides along the cam slot and is pivotable with respect to the lever. A hook on the movable end of the lever extends over the lateral cable to hold the lever in the tensioning position. The lever and a hook which is also slidably disposed in the cam slot cooperatively hold excess cable against the side wall of the tire to keep it from flapping about during use of chains incorporating the fastener.

Abstract: This invention relates to a continuous snow chain comprising three cords or chains disposed in zig-zag patterns and connected to each other in a network of cords or chains of a finite length including two parallel rows of substantially diamond-shaped openings. One cord or chain constituting one boundary of the network of cords or chains is slidably connected to a first retaining cord at each of the zig-zag points constituting the one boundary of the network of cords or chains, which first retaining cord includes means for connecting two extremities thereof to one another. The other cord or chain constituting the other boundary of the network of cords or chains is slidably connected to a second retaining cord at each of the zig-zag points constituting the other boundary of the network of cords or chains, which second retaining cord includes means for connecting two extremities thereof to one another.

Abstract: The present invention relates to a snow chain for vehicle wheels, whereby the snow chain comprises two chain members adapted to extend along the peripheral tread surface of the vehicle wheel when the snow chain is mounted on said wheel. The snow chain comprises tie bars connecting the chain members to each other and adapted to extend transversely to the tread surface when the snow chain is mounted on the vehicle wheel. The snow chain preferably is mounted on arms which are foldable relative to each other and retractable to a position adjacent an end side of the vehicle wheel by means of a retraction device.

Abstract: A fastener for openable and closable side clips for antiskid chains for motor vehicle tires is provided, in which to each end of a side clip is fixed an end portion with a platelike body which, in the fitted state of the chain, is oriented substantially parallel to the side of the vehicle tire. There are further provided a hook and a hooking-in opening on each platelike body in such a way that the hook of one body can be brought into operative engagement with the hooking-in opening of the other body in the locking position. Each hook is constructed in the form of a tongue projecting from the plate-like body so as to slope counter to the closing direction.

Abstract: A novel apparatus for detachably securing together the opposed ends of a lateral cable in a tire chain mounted on a tire. The apparatus includes a plurality of spaced-apart anchor members mounted on one end of the lateral cable and a generally U-shaped clasp joined to the other end of the cable. The clasp includes a base, a first expanse which is joined to and extends outwardly from the base at a right angle, and a second expanse, forming part of the other end of the clasp, which is joined to and projects outwardly from the base, and is inclined away from the first expanse. The clasp further includes an elongate slot which extends longitudinally of the clasp, with opposite ends in the first and second expanses, and having in the second expanse in an enlarged portion which accommodates passage therethrough of an anchor member.

Abstract: A tire and antiskid net for vehicle tires, particularly for tires of heavy earth moving machines, has a plurality of vertical members arranged to extend substantially normally to a tire surface, a plurality of ring-shaped connecting members of a limited length engaging the vertical members and arranged to extend substantially parallel to the tire surface, and a plurality of sleeve-shaped closure members fitted onto the ends of each connecting member in their abutting position so as to hold together the abutting ends of each of the connecting members.

Abstract: An antislip tire chain has provided therewith an inner part and an outer part joined together by a tread part. The inner part includes a fastener formed by a fastener member and a counter fastener member. An introduction opening of the fastener member is open in a direction towards the counter fastener member; via a guide portion extending transversely of the insertion direction of the counter fastener member, the fastener member is joined to an attachment or securing opening. In a region between the introduction opening and the attachment opening, which lies transversely of the guide portion, there is a securing element for the engaged counter fastener member. The fastener can be easily closed, the counter fastener member being reliably secured against unintentional release.

Abstract: A non-skid device for motor vehicle tires comprises at least two strands of cable joined at their ends and having adjustably threaded thereon a plurality of pairs of half-brackets separated from one another by cross pieces in contact with the tread of the tire. The half-brackets are symmetrically disposed and have two branches, a first branch of each half-bracket resting against the tire tread. The second branch of one of the half-brackets in each pair rests against one of the flanks of the tire, and the second branch of the remaining half-bracket rests against the other flank of the tire.

Abstract: An antiskid device and its fittings for a tire including a side chain, a cross chain, a connector, an end link, a hook and a stopper. The side chain includes a side link formed as a two-piece link having two links, one a long link and the other a short link, which are integral with each other. The stopper is angled in transverse cross section and formed with a transverse web of a width large enough to contact a lower portion of the end link and a groove of a width large enough to receive the hook. The cross chain is formed as a cross link of bar material, and the connector is in the form of a link on either end and in the form of a rod in its intermediate portion so that the connector is connected at one end to the cross link and at the other end to the side link.

Abstract: A traction device comprises a traction means such as, for example, a chain mounted on a wheel tire, and a connecting means to connect both end portions of the chain when mounted on. Said connecting means comprises a long extension having a first hook portion at one end, and a short extension having a second hook portion at one end corresponding to said first hook portion, the extension being pivoted to said long extension. Said first and second hook portions are respectively hooked to the end portions of the chain, and by rotating said long extension in a predetermined direction, both end portions of the chain are pulled to approach together so as to perform the connection.

Abstract: In a tire protection chain with plate-shaped components (1) which cover the tread of the tire to be protected, and with at least one chain network (4) located on one side of the tire, the chain network is provided with overload safeguards (7, 8, 9, 14, 18, 22) which form a parting position when the chain network is subjected to extremely high loadings. The overload safeguards are here designed in such a way that no parts can be released and thrown off when the chain network is overloaded.

Abstract: A motor vehicle tire chain system including a plate positioned between a tire rim and a wheel hub, extending outwardly past the tire rim and having a plurality of spaced-apart holes around an external circumference for attaching chain sections. A plurality of individual chain sections, each having a pair of ends adapted to hook in the holes in the hub, position the chain section across the tire tread, traverse the outside of the tire, recross the tire tread and be hooked in the holes on the inside of the tire at a position on the plate opposite the first attaching position. Each chain section is provided with a tensioning device which both tightens the chain and allows it to be easily installed and removed.
