Definitions

  • Elastic hinges of this type have some inconveniences, among which a scarce stability of the coupling between arm and front frame, which enables undesired arm oscillations outside the oscillation plane defined by the usual arm opening and closing movements.
  • an object of the invention is providing a hinge which:
  • FIG. 1 is a perspective view on an enlarged scale of the hinge under a disassembled condition according to the present invention
  • FIG. 5 is a perspective and enlarged view of the hinge under a disassembled condition according to the present invention, equipped with a third arrangement where pieces are directly assembled in the arm seat and covered with a cover
  • FIG. 6 and 7 are respectively a disassembled perspective view and an assembled perspective view of a fourth arrangement of the hinge of the invention. Preferred mode for practicing the invention
  • the box (1) contains two springs (6'; 6") and two nuts (4'; 4").
  • the seat (12'; 12") for the two threaded males (3'; 3") the seat for the springs (16' ; 16") and the seat for the two nuts (14'; 14").
  • the seat for the two males (12'; 12") has a cylindrical section and allows the longitudinal sliding of the threaded males (3'; 3") on axis X, allows the rotation of the threaded male (3' ; 3") when screwing the nut (4'; 4") and, at the same time, leaves a minimum gap between male body (32' ; 32") and seat hole (12' ; 12") .
  • the seat for the two nuts (14'; 14") has such a shape as to prevent the rotational movement of the nuts (4'; 4") when screwing the threaded male (3' ; 3") with respect to axis X, and at the same time allows the longitudinal movement of the nut (4'; 4") with respect to axis X.
  • the box (1) on the externally visible sides can have any shape - even the shape of the eyeglass logo - provided that a space can be created inside for the spring seats
  • seat (21) for the box (1) comprising internal surface (27), front arm surface (28) and two seats
  • the shape of the seat (21) is made by removing material and corresponds to the external shape of the box
  • the seat (21) can be made in the internal part of the arm (2) , in the external part of the arm (2) or can be made in such a way that the box (1) can be seen on both sides of the arm (2).
  • the seat (22'; 22") where the threaded males (3' ; 3") are housed, is composed of two, mutually parallel holes with cylindrical section, with a length (A) which changes according to the arm (2) material.
  • the length (A) is the distance between the front surface (28) and the internal surface (27) of the arm (2).
  • the distance (D) between the two seats (22' ; 22") is longer than the distance (T) which is defined by the side edge (36) and the body (32'; 32") of the threaded male (3' ; 3") to be able to screw the threaded male (3' ; 3") when assembling.
  • the threaded males (3' ; 3") are composed of head (31'; 31"), body (32'; 32"), thread (34'; 34") , through-hole (35' ; 35") and side head edge (36' ; 36") .
  • the two nuts (4'; A") are traditional threaded nuts whose threading (44'; 44") is compatible with the threading (34'; 34") of the threaded males (3'; 3").
  • the springs (6'; 6") are under pressure.
  • the internal diameter (62) of the springs (6'; 6") is sized so that the male body (32'; 32") passes through them.
  • the springs (6'; 6") are tensioned between nut (4'; 4") and the end of the seat (16'; 16").
  • the two springs (6'; 6") are placed in the suitable seats (16'; 16") of the box (1) .
  • the nuts (4'; 4") cannot rotate because the seats (14'; 14") are designed to prevent them from doing this.
  • the threads (34'; 34") of the threaded male (3' ; 3") have a length designed so that, when it gets to the end of the threads, the result is that the springs (6'; 6") are already tensioned on the designed length.
  • the assembly of the elements inside the arm (2) is ended.
  • the threaded males (3' ; 3"), which project from the arm (2) are inserted into their suitable seats (73'; 73") of the front (7) and then hinged with the screw (5) along axis Y.
  • the screw (5) must cross the seat (75) of the front (7) and then enter the hole (35'; 35") of the head (31'; 31") of the threaded males (3'; 3").
  • the major components are identical to the previous embodiments, while the difference lies in the provision of a C-shaped element (100) adapted to be operatively coupled with a recess (102) obtained in the arm (2) and adapted to house therein both springs ( ⁇ ', 6'') and nuts (44', 44' ') .

Abstract

La présente invention concerne une charnière élastique pour lunettes qui comprend : un boîtier (1), un bras (2), deux extrémités mâles filetées (3'; 3"), deux écrous (4'; 4"), deux ressorts (6'; 6") sous pression, une face avant (7). Dans le boîtier (1), deux sièges (16'; 16") sont obtenus pour les ressorts (6'; 6") et deux sièges (14'; 14") sont obtenus pour les écrous (4'; 4"), et ces sièges pour les écrous (4'; 4") sont conçus de manière à permettre le mouvement longitudinal des écrous (4'; 4") par rapport à l'axe X et à empêcher la rotation desdits écrous (4'; 4") par rapport à l'axe X. Le boîtier (1) est assemblé latéralement, sans interférences, dans son siège approprié (21) dans le bras (2) sans exercer de pression. Les deux extrémités mâles filetées (3'; 3") traversent leurs sièges appropriés (22'; 22") dans le bras (2) et sont vissées sur les écrous (4'; 4"), ce qui tend les ressorts (6'; 6"). Ces ressorts (6'; 6") exercent une pression sur la surface interne (17) du siège (21) et par conséquent un contact souple entre la surface (28) du bras (2) et les surfaces (77, 78) de la face avant (7).
