CA 2644307

The invention provides a padlock with a quickly changeable shackle, comprising a locking core, a locking member, blocking balls, a lock body on which two limb receiving chambers and a passage are disposed, and a shackle which takes U-shape defined by a longer and a shorter parallel limbs respectively received in the limb receiving chambers to lock the padlock. A ring groove with an abutment head is disposed at the free end of the longer limb, and a depressed portion with a screw hole is provided on the circumferential surface of the abutment head. A shackle changing screw is threaded into the screw hole and the end face of the screw in the threaded position is higher than the depressed portion and lower than the circumferential surface of the abutment head. The invention further provides a padlock having a freely-convertible deadlock mechanism. 14

L'invention décrite dans la présente divulgation a trait à un cadenas avec arceau aisément interchangeable, y compris un noyau de verrouillage, un élément de verrouillage, des billes d'arrêt, un corps de verrouillage sur lequel se trouvent deux chambres de réception destinées à loger les bras, ainsi qu'un passage. On note aussi un arceau en forme de U défini par des bras parallèles de longueur inégale qui viennent se loger dans les chambres de réception pour verrouiller le cadenas. Une gorge annulaire munie d'une tête d'appui est fixée à l'extrémité du bras le plus long; elle comporte un renfoncement avec trou de vis à la surface de la tête d'appui. Une vis de substitution d'arceau est vissée dans le trou de vis de façon à ce que le bout fileté de celle-ci dépasse la partie creuse, tout en étant moins élevé que la surface ronde de la tête d'appui. L'invention prévoit aussi un mécanisme de serrure à pêne dormant aisément transformable.
