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.
Claims18
A traction sleeve for use in a tire chain, the sleeve comprising a body portion having an outer surface in the form of a right cylinder and at least one end portion having an outer surface flared outwardly from the outer surface of the body portion, the end portion defining a notch providing sharp corners on one end of the sleeve.
A cross member for a cable-type tire chain, the cross member being provided with traction means and having at its opposite ends attachment means for connecting the cross member to respective side members of the cable chain, wherein the cross member comprises a cable covered over at least a part of its length with a sheath comprising a wire wound helically around the cable, with the sheath being free to rotate on the cable, and the traction means comprise traction sleeves freely rotatable on said sheath.
A cross member for a cable-type tire chain, the cross member being a cable provided with traction sleeves and having at its opposite ends attachment means for connecting the cross member to side members of the cable chain, the attachment means including, in each case, a connector element fixed to the end of the cross member and having a head defining a curved outer surface adapted to be received in a complementary connector element attached to one of the side members in a manner permitting rotation of the cross member about its longitudinal axis.
A cable-type tire chain comprising elongate flexible side members adapted to extend circumferentially around opposite side walls of a tire and elongate flexible cross members connected between the side members and being adapted to extend over and across the tire tread, the tire chain including attachment means between the cross members and the side members permitting the cross members to rotate about their longitudinal axes, the cross members comprising cables provided with traction sleeves.
A cable-type tire chain having a pair of elongate side members, cross members connected between the side members, the cross members being cables provided with traction sleeves, and attachment means between the ends of the cross members and the respective side members, each attachment means comprising complementary connector elements secured to a cross member and side member respectively, one of said elements having a head and the other element comprising a plate with a bent-over tab and an opening through which the head is inserted, the head being trapped between the tab and the body of the plate with the tab being flattened toward the body of the plate.
In a cable-type tire chain having a pair of elongate side members and a cross member connected between the side members, the cross member being a cable provided with traction sleeves, attachment means between the cross member and one of the side members, the attachment means comprising complementary connector elements secured to the cross member and side member respectively, one of said elements having a head and the other element comprising a plate with a bent-over tab having an opening through which the head is inserted, the head being trapped between the tab and the body of the plate with the tab being flattened toward the body of the plate.
