Patent number: 4836258Abstract: In order to attach a tire mat to the circumference of a tired wheel, a front flexible elongate member is slidingly passed through attachment fittings on the mat spaced around the periphery of the front side of the wheel, and a rear flexible elongate member is slidingly passed through attachment fittings on the mat spaced around the periphery of the rear side of the wheel. Respective sliding attachment members are then used to attach parts of each elongate member together so as to enable relative sliding movement between the parts and so as to cause the elongate member to form an intermediate loop portion which extends through the attachment fittings on the associated side of the wheel and a further portion outside the loop portion.Type: GrantFiled: July 5, 1988Date of Patent: June 6, 1989Inventor: Reginald C. L. Ellis

Patent number: 4648434Abstract: Antiskid device for motor vehicle tires with an inner fastening or mounting engaging with the inside of the tire and with an inner fastening or mounting for chain strand portions extending over the tire tread, in which in the fitted state, the inner fastening has an approximately circular construction and has a central fastening section, to each of whose two ends is swivellably fixed a side part by means of a swivel joint and for fitting the inner fastening, the side parts can be opened outwards from the central fastening section and are in each case pretensioned by means of a spring device in the direction of a closed form of the inner fastening. In order to further facilitate fitting, particularly in the case of narrow or confined wheel cases, it is provided that the central fastening section comprises at least two portions, which are interconnected in a swivellable manner relative to one another and are also pretensioned in the direction of a closed form of the inner fastening.Type: GrantFiled: September 24, 1984Date of Patent: March 10, 1987Assignee: Acciaierie Weissenfels S.p.A.Inventors: Carlo Melzi, Paolo Gregorutti

Patent number: 4598749Abstract: A vehicle tire with traction-improving devices, wherein the basic tire has a plurality of uniformly spaced apart cross grooves running essentially from sidewall to sidewall. Each groove is fitted with an inflatable bag or bladder which, when uninflated, retracts within the circle of the road-engaging surface of the tread. An annular manifold is affixed to at least one sidewall and is connected by conduits to the cross members. This manifold has a valved air inlet which may be used to pressurize the cross members via the manifold and thus to project the inflated members radially beyond the circle of the tread so that they engage the road surface. Depressurizing the manifold of course causes the members to retract. Each cross member is equipped with some form of traction-improving substance, structure or the like to enhance road grippability, especially in slippery road conditions.Type: GrantFiled: January 14, 1985Date of Patent: July 8, 1986Inventor: Anthony V. Mandekic

Patent number: 4588010Abstract: An anti-skid device for motor vehicle tires is provided including front and rear holding devices, which lie against the inside and outside of the tire when the chain is mounted, and between which chain strand sections extend over the running surface of the tire. One of the holding devices which usually is the rear holding device in the mounted state, is essentially circular and has a rigid middle section and two rigid side sections, one end of each of which is attached by pivotal connections to an end of the middle section in such a way that it can be pivoted. Pretensioned spring devices are provided at the pivot connections to bias the side sections toward each other in the mounted condition after the rear holding device is passed over the tire with the side sections pivoted outwardly. Locking devices for securing the two ends of the side sections together in the mounted position are also provided.Type: GrantFiled: February 7, 1984Date of Patent: May 13, 1986Assignee: Acciaierie Weissenfels S.p.A.Inventors: Carlo Melzi, Paolo Gregorutti

Patent number: 4542779Abstract: 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.Type: GrantFiled: March 23, 1984Date of Patent: September 24, 1985Assignee: Eisen- und Drahtwerk Erlau AktiengesellschaftInventors: Anton Muller, Hubert Konig, Ludwig Wolfbeis

Patent number: 4508150Abstract: A lightweight device for obtaining improved traction efficiency of rubber tired vehicles without adding ballast weight. The device has high-strength, thin-gauged traction intensifying means secured to a driving tire, providing higher drawbar pull at higher rate of travel speed by utilizing stronger sub-surface soil and extended tire life; and includes actuating means, for engaging and disengaging the traction enhancing means for convenient conversion to allow travel on pavement.Type: GrantFiled: January 3, 1984Date of Patent: April 2, 1985Assignee: TG Strips, Inc.Inventor: Thorvald G. Granryd

Patent number: RE45255Abstract: Self-tightening snow chain for attachment to a vehicle wheel to provide traction. The preferred self-tightening snow chain includes a traction cable and a tensioning device including a housing having a top including a set of housing teeth, a bottom and at least one aperture; a lever interconnected to the housing; a ratchet spool within the housing having a set of ratchet teeth that mate with the housing teeth and a channel between upper and under surfaces to receive a cord that is interconnected with the ratchet spool; a tension spring that places a bias on the ratchet spool toward a wind-up direction; and a wave spring. A preferred tensioning device includes a cord sub-unit having two knobs, one on each end, and a grommet encircling the cord. A method of assembling the tensioning device is also disclosed.Type: GrantFiled: June 20, 2013Date of Patent: November 25, 2014Assignee: Peerless Chain CompanyInventors: John J.
