Abstract: A lever-operable fastener for pulling two parts of a skiing boot toward each other comprises a rack (1) , which is secured to one of said parts and adapted to receive a tensioning lever (2). A tensile element (3) is connected to the other of said parts and acts on said tensioning lever at a point which is spaced from a detent element (4), which is provided on the tensioning lever (2) and is adapted to extend into a tooth space of said rack (1) so as to define a fulcrum for said lever.

Abstract: A tensioning lever is mounted on one part of the shoe. A tension loop is mounted on another part of the shoe and adapted to be hooked into the tensioning lever. The tensioning lever can be moved along a rack to tension the fastener and is restrained by releasable means against being pulled back.Before a retensioning of the fastener, the latter should not be relieved from tension entirely. For this purpose, the tensioning lever cooperates with a ratchet mechanism for tensioning the fastener. The ratchet mechanism comprises a driver which cooperates with the rack and which consists of or is adapted to move with the tensioning lever.

Abstract: The fastener comprises two fastener members, one of which consists of a tension strap and the other of a strap retainer. One of the fastener members is provided with teeth, which are interengageable with a tensioning lever, which is associated with the other fastener member. Strap-restraining means are also provided, which comprise a locking pawl that is mounted on said other fastener member and cooperates with said teeth.The teeth have inclined tooth spaces and in order to facilitate the operation of the fastener are provided either on the tension strap on its inner side facing the shoe or on the strap retainer on its outer side facing away from the shoe. That part of the strap-restraining means which cooperates with the tension strap extends away from the shoe and is firmly connected to the strap retainer.

Abstract: A cleated chain wrapping is disclosed for use on mounted automotive wheels. The wrapping utilizes a plurality of chain pairs attached to the wheel and extending transversely across the tread surface. Cleats connect one chain in each pair to an adjacent chain in an adjacent pair.

Abstract: A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is provided with a flexible element that tightens the chain on the road-engaging surface. The outer end of the flexible element, which may be a chain, a rope or the like, is then secured to the holder on one of the surfaces of the wheel. There is provided a tightening mechanism so as to ensure self-locking of the tire-chain assembly on the wheel.

Abstract: A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is of variable diameter, so that it can be fitted over the tire and then have its diameter decreased to allow the traction chain to be tightened on the wheel. Mechanism on this inner holder is connected via a flexible element that passes over the road-engaging surface of the wheel to the outer face of the wheel so that a pull on this mechanism will reduce the diameter of the inner holder and tighten the chain assembly on the wheel. The outer end of this flexible element, which may be a chain, is then secured to the holder on the outer surface of the wheel.
