20130312884 | CHAIN LINK WITH SPIKES FOR ANTISKID CHAINS, AND ANTISKID CHAIN COMPRISING SUCH CHAIN LINKS - A chain link for antiskid chains of vehicle tires, which is provided in order to improve the grip properties, in particular on a smooth underlying surface, with one or more spike(s) which project on one of its sides. Each spike has, perpendicular to its longitudinal extent, a cross-section whose outer edge has a corrugated peripheral contour of successive troughs and peaks. | 11-28-2013 |
20130228257 | CHAIN FOR MOUNTING ON A VEHICLE TIRE - The invention relates to a chain for mounting on a vehicle tire, in particular an anti-skid chain, wherein the chain comprises a mesh, which is arranged on the tread of a vehicle tire when the chain is mounted, and is connected to an inner retaining strand on the vehicle tire inner side via inner shoulder chains and to an outer retaining strand on the vehicle tire outer side via outer shoulder chains, wherein the mesh is substantially composed of straight chain links, and the inner shoulder chains are composed of twisted chain links at least in one section, which is arranged on the vehicle tire inner side when the chain is mounted. The invention further relates a chain strand, for example for use in such a chain. | 09-05-2013 |
20120090751 | TENSION DEVICE FOR A NONSKID CHAIN - In a tension device for a nonskid chain, a winding reel is supported, so that it can rotate about its axis inside the housing and is prestressed in the winding direction and has a gear rim with teeth arranged along its circumference. A tension line that can be retracted into the housing can be connected to the winding reel, such that a ratchet in a first position (A) blocks a rotational movement of the winding reel in the tension direction by engagement of the ratchet in the teeth. Areas free of teeth on the circumference of the gear rim of the winding reel alternate with areas with teeth. | 04-19-2012 |
20120060986 | ANTISKID CHAIN WITH SIDEWALL PROTECTION COVERS - In order to protect the sidewall of a vehicle wheel from damage caused by an antiskid chain mounted on the wheel, a sidewall protection cover having a U-shaped body is provided. The sidewall protection cover accommodates a chain link of a chain side strand that is situated against the sidewall. The body is preferably one piece and has two wings that are connected along a spine, where the wings enclose a space for accommodating the chain link, and at least one of the wings has a holding element, on its side that faces inward, in the form of a projection for holding the chain link and/or a connection element suspended on it in place between the wings. | 03-15-2012 |
20110284677 | TENSIONING LOCK - A tensioning apparatus (60) for an anti-skid chain to be mounted on a vehicle wheel, a tensioning strand (7) which can be pulled into the housing is connected within the housing (61) to a winding roll (62) with a ratchet wheel (65), which winding roll is pretensioned in the winding direction and rotatable about its axis. A ratchet pawl (64) associated with the ratchet wheel can be moved to the outside under the influence of centrifugal force during wheel rotation, starting from a release position not in engagement with the ratchet wheel and the tensioning strand is not blocked, causing an engagement of the ratchet pawl in the ratchet wheel and a blocking of the tensioning strand against its tensioning direction. A magnetic holding element (68) cooperates with the ratchet pawl and counteracts deflection of the ratchet pawl from the release position during standstill or slow rotation of the wheel. | 11-24-2011 |
20100307127 | TRACK LINK FOR ANTI-SKID CHAIN - The present invention pertains to a chain link for an anti-skid chain, wherein the chain link is designed as a straight chain link with an essentially oval shape with an upper and a lower side wall. The outer cross-sectional area of the chain link has a half-round design and the inner cross-sectional area has an angular design. At the same time, the present invention pertains to an anti-skid chain with a chain mesh, which has chain links according to the present invention. | 12-09-2010 |
20100078108 | TRACK LINK FOR ANTI-SKID CHAIN - The invention relates to a chain link for an anti-skid chain for vehicle tires, whereby protruding studs arranged on the chain link, and at least one stud is arranged on the lengthwise side of the chain link and the longitudinal central axis of the stud is inclined with respect to the central plane of the chain link. The chain link is thus implemented as either a drawn, milled or forged chain link. The invention further relates to an anti-skid chain that exhibits chain links according to the invention. | 04-01-2010 |
20100065176 | ANTI-SKID CHAIN - In an anti-skid chain with a continuous chain mesh with track crosses and a side cable fitted on a tire side when mounted, e.g. an outer side cable fitted on the outer side of the tire, as well as a tension cable fitted on the other tire side, e.g. an inner cable lying on the inner side of the tire, there are connecting elements on the tension cable, into each of which either a hook connecting the tension cable with at least one track cross or chain parts of the continuous chain mesh are directly hooked, and which are clamped on a sheathing of the tension cable secured against slippage. At least one protrusion for fixing or clamping a sheathing of the tension cable can additionally by provided on an inner surface of the connecting elements facing towards the tension cable. | 03-18-2010 |
20100065175 | ANTI-SKID CHAIN WITH RIM PROTECTION COVERING - In an anti-skid chain with a continuous chain mesh with track crosses and a side cable fitting on an (outer) tire side when mounted, the track crosses are connected to the side cable by hooks which are hooked into at least one chain link of the side cable, wherein each hook is provided with a rim protection covering surrounding the hook and the at least one chain ink. The rim protection coverings surround the respective chain links of the side cable, while a part of the hook that provides a connection with the track crosses is protruding from the rim protection covering. | 03-18-2010 |
20100034578 | TURNBUCKLE - A turnbuckle for an anti-skid chain that can be mounted on the wheel of a vehicle. A tension cable is connected inside the turnbuckle housing to a winding roll that is pre-stressed in the winding-up direction and mounted so that it can be rotated about its axle. A ratchet wheel with at least one ratchet catch allocated to it is provided on the winding roll and the tension cable can be blocked against its direction of tension by gripping of the ratchet catch into the ratchet wheel. The ratchet catch is moved at least incrementally outwards from the idle position when the wheel isn't moving, in which it is disengaged from the ratchet wheel and the tension cable is not blocked, under the action of the centrifugal force upon rotation of the wheel, and this movement effects a gripping of the ratchet catch into the ratchet wheel. | 02-11-2010 |
