Definitions

  • the invention relates to a spring hinge for a pair of glasses with a hinge part which is displaceably guided in a bracket-side housing in the longitudinal direction of the bracket, with an armature which projects from the hinge part in the direction of displacement and engages in a housing opening, which has an anchor rod and a crossbar at the end of the anchor rod, and with two helical springs provided laterally next to the anchor rod and parallel to the anchor rod, which are supported with their hinge-side end on an abutment belonging to the housing and with their opposite end on the crossbar of the anchor.
  • the invention is therefore based on the object of designing a spring hinge for glasses of the type described at the outset in such a way that the hinge part with the armature and the two coil springs can be inserted after the housing has been fastened to the temple.
  • the invention solves this problem in that the two coil springs are inserted into a housing bore that is open relative to the housing opening for the anchor rod, and that the housing bores each receive a closure piece that forms the abutment for the coil spring.
  • the two housing bores for receiving the coil springs are open relative to the housing opening for the anchor rod, the crossbar of the armature at the end of the anchor rod engages radially in the housing bores for the coil springs, so that the hinge part with the anchor also from the hinge-side end face of the housing in the axial direction can be inserted into the housing opening before the coil springs are inserted into the housing bores. Need it therefore, the housing bores receiving the coil springs are only to be closed by locking pieces in order to complete the assembly of the spring hinge. The locking pieces form the housing-side abutments for the coil springs, which act on the hinge part via the armature under a corresponding pretension in the sense of being drawn into the housing.
  • the locking pieces forming the abutments for the helical springs can be fixed axially in different ways with respect to the housing bores, particularly simple constructional relationships result when the locking pieces are screwed into the housing bores.
  • the screw connection namely allows simple loosening of the closure pieces and thus replacement of the hinge part or the coil springs if necessary.
  • FIG. 1 shows a spring hinge according to the invention for a pair of glasses in a longitudinal section parallel to the hinge axis
  • FIG. 2 shows a section along the line II-II in FIG. 1
  • FIG. 3 shows a section along the line III-III in FIG. 1
  • FIG. 4 shows a cross section through the spring hinge along the line IV-IV of FIG. 1 on a larger scale.
  • the spring hinge according to the illustrated embodiment has two hinge parts 2 and 3 connected by a hinge axis 1, of which the hinge part 2 is fastened to a temple jaw, while the hinge part 3 is slidably mounted in a housing 4 fastened to a temple piece.
  • the hinge part 3 which forms a central hinge flap with a bearing eye for the hinge axis 1, is connected to an armature 6 which engages in a housing opening 5 and which has an anchor rod 7 which can be displaced in the housing opening 5 but is secured against rotation and has an end Crossbar 8 has.
  • a housing bore 9 is provided, which is open towards the housing opening 5 in order to create a radial passage for the crosspiece 8.
  • the hinge part 3 with the armature 6 can be inserted axially into the housing 4 from the end side of the housing 4 before helical springs 9 enter the threaded bores 10 can be used to act on the hinge part 3.
  • the housing bores 9 are closed on the hinge side with the aid of locking pieces 11 which, according to the exemplary embodiment, are screwed into an end threaded section of the housing bores 9 and form an abutment for the coil springs 10, which are thus under a corresponding pretension between the crosspiece 8 of the armature 6 and the closure pieces 11 are clamped.
  • hinge part 3 is pulled resiliently against the housing 4 by means of the coil springs 10 via the armature 6, the hinge part 2 being pressed against the end face of the housing 4 with one of two stop surfaces 12, 13, depending on the position of the eyeglass temple, to either secure the extended position of use via the stop surface 12 or the pivoted-in rest position of the temple on the stop surface 13.

Abstract

L'invention concerne une charnière à ressort pour une paire de lunettes, comportant une partie charnière (3), guidée de manière coulissante dans un boîtier (4) côté branche dans le sens longitudinal de la branche, un élément d'ancrage (6) s'engageant dans une ouverture (5) du boîtier et faisant saillie de la partie charnière (3) dans le sens de coulissement, lequel élément d'ancrage (6) présente une tige d'ancrage (7) et une traverse (8) à l'extrémité de la tige d'ancrage (7), ainsi que deux ressorts hélicoïdaux (10) parallèles à la tige d'ancrage (7) et placés de chaque côté de cette tige d'ancrage (7), lesquels ressorts s'appuient sur une butée, associée au boîtier, par leur extrémité côté charnière et sur la traverse (8) de l'élément d'ancrage (6) par leur extrémité opposée. L'objectif de cette invention est de permettre une insertion de la partie charnière (3) et des ressorts hélicoïdaux (10) après une fixation du boîtier (4) sur la branche des lunettes. A cet effet, les deux ressorts hélicoïdaux (10) sont insérés axialement dans un alésage respectif (9) du boîtier qui est ouvert par rapport à l'ouverture (5) du boîtier destinée à la tige d'ancrage (7) et les alésages (9) du boîtier logent chacun une pièce d'arrêt (11) formant la butée pour les ressorts hélicoïdaux.
