<p>A hinge (12), in particular for the lateral arms (16) or the bridge of a metal wire, even rimless, spectacle mount; the hinge having a first portion defined by an end group of over one and a half (e.g. one and three-quarter) coils (14) and formed by bending a first metal wire element of the mount, e.g. the connecting end of a lateral arm (16), and a second portion (11) defined by a partially open toroid portion (17) (at least one, even incomplete, coil or circle or ring portion) formed by bending one end of a second (fixed) metal wire element of the mount; the (partially open) coil or toroid portion of the second portion winding about an angle of over 180 DEG and being engaged internally by the group of coils (15) of the first portion to permit free relative rotation of the group of coils in both directions; the group of movable coils (15) and the fixed coil (17) (or vice versa, the movable coil and the fixed group of coils) acting as a screw-nut screw connection; the fixed coil (17) at one end (with or without a straight portion) forming a stop surface for arresting rotation of the lateral arm beyond the closed position (19); the movable coils (15) of the lateral arm (16) terminating with a straight portion (21) parallel or not (to determine an opening stop angle of other than 90 DEG ) to the lateral arm; and the straight portion (21) cooperating as a stop surface with a branch (6) of the mount to arrest rotation of the lateral arm (16) in the fully open position. <IMAGE></p> |
