CA 2221319

A nail for fixing a shoe to a hoof includes a head (20), and a shank (12) extending from the head (20) generally along a centreline (14) and terminating in a tip (13). A reaction region (24) is formed in the shank (12) adjacent the tip (13) and has a flattened profile having front and rear surfaces (25, 26) interconnected by respective edge surfaces (27, 28). In the reaction region (24) the front surface (25) is convexly curved to incline the front surface (25) relative to the centreline (14) of the shank (12) and the edge surfaces (27, 28) converge relative to each other towards the tip (13), whereby, on forcing the nail into the hoof, the reaction region (24) is adapted to produce a resultant force on the nail caused by engagement of the reaction (24) with the hoof, the resultant force being adapted to predispose the nail to bend about the rear surface (26) of the reaction region (24). Also disclosed are processes for forming a horseshoe nail.

L'invention concerne un clou permettant de fixer un fer à un sabot, qui comprend une tête (20), une tige (12) partant de la tête (20) et se terminant en pointe (13), s'étendant de manière générale le long d'une ligne centrale (14). Une zone de réaction (24) est formée dans la tige (12) à proximité de la pointe (13) et comporte un profil aplati à surfaces avant et arrière (25, 26) interconnectées par des surfaces marginales (25, 26) respectives. Dans la zone de réaction (24), la surface avant (25) est formée de manière convexe, afin de s'incliner par rapport à la ligne centrale (14) de la tige (12) et les surfaces marginales (27, 28) convergent les unes par rapport aux autres en direction de la pointe (13). Lorsque le clou est enfoncé dans le sabot, la zone de réaction (24) est adaptée afin de produire une force résultante sur le clou, due à la mise en contact de ladite zone de réaction (24) avec le sabot. La force résultante est adaptée afin de prédisposer le clou à se courber au voisinage de la surface arrière (26) de la zone de réaction (24). L'invention concerne également des procédés de forgeage de clous pour fer à cheval.
