Abstract
A spectacle-frame side arm is provided which is capable of lateral articulation intermediate its ends to conform to the shape of the wearer's head. The side arm comprises front and rear parts articulated together, and a longitudinal reinforcing lamina extending between the arm parts at least in their zone of articulation. In order to resist torsional stresses about the longitudinal axis of the side arm, the articulated ends of the side-arm parts are formed as interplaced tenons and mortices which extend perpendicularly to the said longitudinal axis. Preferably, the opposing surfaces of the interplaced tenons are separated from each other by a metal spacer element which has a profile similar to that of the articulated ends of the side-arm parts considered in a plane parallel to the longitudinal median plane of the side arm.
Claims8
A side arm for a spectacle frame, said side arm comprising a
- front part arranged to be hinged to the front of the frame,
- a rear part shaped to engage over the ear of the wearer and articulated at its forward end to the adjacent rear end of said front part, and
- a longitudinal reinforcing element which at least in the zone of articulation of said front and rear parts is in the form of a flexible lamina situated in the vertical longitudinal median plane of the spectacle side arm, the adjacent ends of said front and rear parts being so formed that their facing surfaces are spaced from each other by a distance which progressively increases as the distance from said median plane increases, and the said adjacent ends of the front and rear side-arm parts each being formed with tenons and mortices which extend transversely to the longitudinal direction of said side arm and respectively engage with the mortices and the tenons of the other said side-arm part, each said tenon having two surfaces which at least partially face upwards and downwards respectively.
