A link member for a tire chain, comprising a body including a cavity for receiving a portion of a ring element therein, the body also including an opening for inserting the ring element into the cavity, said body further being adapted to receive a retaining member for closing the opening and retaining the ring element in the cavity.

A tire rim of a motor vehicle includes a substantially cylindrical body for holding a tire, and a hub connected to the body through radial members, and has an outer face facing, in use, the outside of the vehicle, and an opposite inner face. At least one elongate flexible element associated with the rim can reach a resting configuration within the rim, and a working configuration, extended with respect to the resting configuration, of such a length as to allow the tire to be surrounded, in which each flexible element is wound around the tire to form a snow chain. The rim includes at least one retaining member at a zone of its inner face, to be engaged by a portion of a flexible element in its working configuration.

System for attaching a tread formed as an elongated element to a tyre, such as a bicycle tyre. The system comprises at two elongated attachment members configured to be fastened along the circumference of a side of the tyre. The element and the members are provided with mutually interlocking means for engagement with each other when the element is attached to the tyre. The mutual interlocking means may be a zipper, or a hook-and-loop system, or a dual-lock system.

The present invention relates to an automotive tyre non-skid device for snowfields to increase adhesion to pavement covered with ice or snow, in particular to a diagonal bead chain stress reducing pinch plate and a diagonal bead chain. Through configuration of stress reducing pinch plates and stress reducing transition chains disposed on two sides of a second connecting assembly, concentrated stress at the connector roots of steel cables of the stress reducing transition chains are isolated, dispersed and relieved, and the service life of the steel cables are prolonged. At the same time, the present invention has the advantages of simple structure, stable performance, convenient modification and low manufacturing cost.

This invention discloses an automatic locking device for snow anti-skid chains. Wherein the snow anti-skid chain comprises a ratchet wheel lock catch and a anti-skid chain; the anti-skid chain is respectively fixed at the buckle and the outer part of the housing aforesaid, and extends towards three directions. The ratchet wheel lock catch is used to make the anti-skid chain to attach to automobile tires firmly and is controlled by pressing two buttons on its lower side, which is different from existing operational actions of braking off and twisting. The pressing action is simple and available for one hand operation. The overall structure is simple and reliable, conforming to use habits of control actions by users.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A snow chain device for providing good traction to a vehicle tire on a snowy surface is described. The device is capable of being removably mounted on the tire with reduced physical effort and in multiple configurations. The device can be used in modular fashion and a range of patterns making it suitable for use on different tires as well as under varying driving conditions. Also it is possible to cover the entire surface of the tire as well as a partial surface. The device has several link members and several base members. The base members can be affixed to the external tire surface and the link members can be removably secured to the base members.

A sleeve for covering vehicle wheels includes a fabric band having an annular arrangement and therefore with a circumferential path as a result of the annular geometry, the band having such proportions and being enabled to cover and surround an external region of a wheel of a vehicle. The fabric band has a central area along its circumferential path and at least one lateral area adjacent to the central area following the same circumferential path. The at least one adjacent lateral area of the band has a surface density value lower than the surface density value of the central area of the same band. The band also presents a textile or fabric continuity in the mutual contact between its central area and at least one adjacent lateral area, the band being formed in one piece or textile body.
