CA 2301571

A shoe cleat is adapted to be removably secured in a holder provided on the shoe sole. In a combination of shoe cleat and holder, a screw-threaded spigot (12) on the cleat is inserted with rotation into a complementary socket (18) of the holder, and a locking means (26, 28) becomes interengaged to resist subsequent unscrewing of the assembly. The locking means comprises a ring of free-standing posts (34, 42) extending axially from the cleat and a ring of radially-projective teeth (26) on the holder, the rings being co-axial with the screw axis. During of least later stages of insertion of the spigot (12) into the socket (18), on relative rotation of the rings, engagement of the teeth (26) with the posts (34, 42) causes the posts (34, 42) to deflect resiliently and engagement of the teeth (26) between the posts (34, 42) causes interangagement of the locking means.

L'invention concerne un crampon de chaussure conçu pour être fixé amovible dans un porte-crampon prévu sur la semelle de la chaussure. Dans une combinaison de crampon de chaussure et de porte-crampon, on insère en tournant un élément saillant (12) fileté situé sur le crampon dans une cavité (18) complémentaire du porte-crampon, et un dispositif de blocage (26, 28) se met en prise entre les deux éléments de façon à résister à un dévissage ultérieur de l'ensemble. Le dispositif de blocage comporte un anneau comportant des tiges (34, 42) autonomes s'étendant axialement à partir du crampon, et un anneau de dents (26) saillant radialement sur le porte-crampon, ces anneaux étant co-axiaux par rapport à l'axe de vissage. Au cours d'étapes ultérieures d'insertion de l'élément saillant (12) dans la cavité (18), lors de la rotation des anneaux l'un par rapport l'autre, la mise en contact des dents (26) avec les tiges (34, 42) provoque un fléchissement résilient des tiges (34, 42), et l'engagement des dents (26) entre les tiges (34, 42) provoque la mise en prise du dispositif de blocage.
