Abstract (en)
[origin: WO9532448A1] The two pieces (1<u>a</u>, 1<u>b</u>) of the slit circle carrying the glass (9) of spectacles are assembled and tightened by means of a screw (2) which is screwed into the piece (1<u>a</u>). Said screw (2) carries a coil spring (5) housed in a cavity (3) of the piece (1<u>b</u>) and which bears, on the one hand, to the bottom (1<u>d</u>) of said cavity (3) and, on the other hand to the head (2<u>b</u>) of the screw. The screw is locked to the piece (1<u>a</u>) by means of a circlip (8) engaged into an annular groove (7) made in the screw (2) at the vicinity of its end. The thickness of the circlip (8) depends on the longitudinal position of the screw (2) with respect to the piece (1<u>a</u>) of the glass-carrier circle once the desired tension of the spring (5) has been reached.
