Modified Links Patents (Class 152/243)
  • Patent number: 10016031
    Abstract: The present invention(s) seeks to protect Applicant's link, link chain and methods of making, transforming and using such. The link, for use in series to form a multi-positionable link chain includes a through hole and a first and a second diagonal channel on a top and a bottom side running in opposite directions. Generally, the geometry of the links, and specifically, material removed from and/or sharpened edges of the through hole, the diagonal channels and/or corner portions of the modified rectangular solid links, is such to allow for relative rotation and/or multiple points of connection of adjacent links. The link chains of the present invention(s) are flexible in the length, width and height dimensions to allow adaptable transformation in a plurality of stable configurations. And they can include a clasp for ornamental and/or decorative use.

The periphery preferably is covered with an anti-skid material, e.g., rubber. Chains are pre-turned or twisted in the same direction a tire tends to turn them when rolling over them to avoid further twisting with consequent shortening in use and they are given a non-circular, e.g., square cross section to increase their anti-skid properties. The chains are welded at one end to a steel ring which is removably fastened to the under surface of a disk by bolts.

  • Patent number: 4366850
    Abstract: A cable-type tire chain comprises side members adapted to extend circumferentially around opposite side walls of a tire and cross members connected between the side members so as to extend over and across the tire tread. The cross members comprise cables connected to the side members in a manner permitting rotation of the cross members about their longitudinal axes. The cross member cables have sheaths of helically wound wire which are free to rotate on the cables, and traction sleeves are freely rotatable on the wire sheaths. The traction sleeves have cylindrical body portions and outwardly flared end portions. Notches in the end portions of the sleeves define sharp corners at the ends of the sleeves for biting into ice and the like.

  • Patent number: 4349060
    Abstract: The present invention relates to an anti-skid device for improving the traction of a wheel on an automotive vehicle on the ground. The invention relates also to a method of producing such anti-skid devices. The anti-skid device comprises at least one chain intended to run along the wall(s) of the tire and a plurality of chains intended to surround the entire tread face of the tire. The various chains are interconnected. The interconnection is provided by welding a certain number of neighboring links of two adjacent chain lengths together. The chain length may preferably be equipped with additional gripping elements welded on at least some of the links.

  • Patent number: 4306605
    Abstract: A connector for chains, particularly tire chains, comprises a substantially C-shaped main body (1) whose free arms (3,4) define an insertion gap (5). In a position lying opposite the insertion gap (5) the yoke portion (2) of the main body (1) has roof shaped surfaces (11,12) the apex line of which is intersected by the axis of a stepped bore (6) for receiving a retaining pin (7,14,19) and extends at a right angle to the place of the arms (3,4) and the yoke portion (2). The retaining pin (7,14,19) has an annular flange (8) and is held in its retaining position by means of at least one securing element (10) which is seated in a bore (9,17,18) intersecting the stepped bore (6).

  • Patent number: 4263954
    Abstract: A cable type tire chain has traction sleeves on the cross members located only adjacent to the shoulders of the tire. The center portion of the cross members adjacent to the middle of the tire tread is free of traction sleeves. The traction sleeves are spaced away from the middle of the tire tread by either a coil spring through which the cross member cable extends or by beads attached to the cable. The cross members are attached directly to the side members of the tire chain by flat profile hooks formed from rectangular strips of metal, so that the cross members lie close to the sidewalls of the tire. The invention provides improved traction and reduced wear of both the tire and the tire chain.

  • Patent number: 4219065
    Abstract: A tire protector for reducing wear on the tires of heavy vehicles consisting of two or more parallel rows of spaced apart chain links. These links are joined by couplings members and consist of metal bars or wires which are bent so that they encircle each two chain links and that the ends of the bars or wires overlap side by side. These overlapping ends are positioned to face upwardly and flat when the protector is mounted to a tire. As a result only a relatively small area comes continually with contact with the ground and is thus exposed to wear and tear. This contacting area is strongly enforced due to the thickness of the sidewise overlapping ends, as a result, parts of the protector, such as the chain links and the bars or wires which form the coupling member, can be made fairly thin as they are not exposed to considerable wear thereby reducing the overall cost of producing the protector and also extending its lifetime.

  • Patent number: 4161976
    Abstract: Anti-skid tire chain comprises a network positionable during use in the region of the tire tread. The network includes two parallel chains extendable along opposite sides of the tread, a plurality of rings interconnected into each chain for guiding same and a plurality of straps. Each strap interconnects one ring from one chain with one ring from the other chain and each crosses over another strap. At least one post is connected to a strap in the region of each intersection and is composed of synthetic material.

  • Patent number: 4155389
    Abstract: A cable tire chain in which traction sleeves of the cross members are of the type in which a sleeve is formed by bending a generally rectangular metal strip into a generally cylindrical shape so that a pair of opposite edges of the strip are opposed in proximity and extend generally longitudinally of the sleeve. The opposed edges meet at a center region of the edges and are spaced elsewhere to provide exposed sharp corners for biting into ice. Each sleeve has a projecting tab at one end only for spacing that sleeve from an adjacent sleeve, the tab and other projections having sharp corners also.

  • Patent number: 4106542
    Abstract: A tire chain comprising tread links formed with a perforation and connectors that are loops threaded through the perforations in three or more tread links interconnecting the tread links to form a network of closed figures. The connectors are loops of a carbon steel rod with the ends of the loops lapping each other and being welded together along the length of their adjacent surfaces. The tread links and connectors are of different carbon steels whereby after heat treating each is hardened throughout its thickness with the tread links having a surface hardness in the range 46 to 54 Rockwell C and the connectors having a core hardness in the range 15 to 35 Rockwell C.
