Abstract
(EN) Disclosed are lock nuts (100) and (100a) for preventing a leg bolt (4) from loosening from a leg assembly supporting electric home appliances, and a wrench (500) for loosening or tightening the lock nuts (100) and (100a). The lock nuts (100) and (100a) includes a hub having a screw hole (111), a plurality of ribs extended in a radius direction from a circumferential surface of the hub, and having sides (125) and (125a) over which the wrench (500) or a finger is hooked, and supplementary member (130) provided allowing the wrench or finger to access form the radius direction of the hub to the sides (125) and (125a), and coupling the ribs (120). The wrench (500) includes a long grip having at least one projection (550) and (560) on an outer circumferential surface thereof, and a box end (530) or an open end (520) provided at either of both ends thereof.
(FR) L'invention concerne des contre-écrous (100 et 100a) destinés à empêcher un boulon (4) de pied de se desserrer d'un ensemble de pieds supportant des appareils domestiques électriques, et une clé (500) permettant de desserrer ou de serrer les contre-écrous (100 et 100a). Les contre-écrous (100 et 100a) comportent un embout doté d'un trou de vis (111), plusieurs nervures s'étendant dans le sens radial depuis la surface circonférentielle de l'embout, des côtés (125 et 125a) auxquels la clé (500) ou un doigt est accroché(e), et un élément supplémentaire (130) permettant à la clé (500) ou au doigt d'atteindre, dans le sens radial de l'embout, les côtés (125 et 125a) et accouplant les nervures (120). La clé (500) possède un long manche comportant au moins une saillie (550 et 560) sur sa circonférence, et une section carrée (530) ou une extrémité ouverte (520) à une de ses deux extrémités.
