Description

4594DEP 2875609 1

  The present invention relates to eyeglasses or sunglasses, and more particularly to such glasses comprising a bezel face and side glasses branches hinged to the bezel face by hinges.

  The invention aims to make interchangeable or removable glasses branches vis-à-vis the face of the telescope, especially so that the user can change the appearance of his telescope by changing the branches at will.

  Already known interchangeable glasses branches plastic, in which the branches engage by snapping on the bezel face. These spectacle structures have the disadvantage of rapid wear of the means for retaining the branches on the face of the telescope, and this results in a risk of inadvertent separation of the face of the telescope vis-à-vis the branches.

  The invention thus aims to design a new assembly device structure between a bezel face and an articulated bezel branch, allowing the interchangeability of the bezel branch without requiring the use of specific tools, while avoiding the occurrence of premature wear of the assembly device, wear likely to adversely affect the holding capacity of the bezel branch on the bezel face.

  Another object of the invention is to facilitate the operation of the assembly device, while ensuring good holding capacity of the bezel branch on the bezel face.

  Simultaneously, the invention aims to design such an assembly device which occupies a reduced volume, so as to be used on eyeglasses or sun whose branches are light and thin.

  Another object of the invention is to avoid weighing the face of the telescope, in order to maintain satisfactory comfort of the telescope for the user.

  Another object of the invention is to design such an assembly device which is particularly robust, avoiding the risk of deterioration in the normal conditions of use of the glasses.

  To achieve these and other goals, the invention provides a connecting device between a bezel face and a bezel branch hinged to the bezel face by a hinge having a proximal portion associated with the bezel face and a distal part associated with the telescope arm; the assembly device is such that: - the distal hinge portion is removably attached to the bezel branch by longitudinal embedding means and releasable axial retention means 4594DEP 2875609 for assembling the telescope branch by axial thrust and separating the telescope leg by axial traction, the longitudinal embedding means provide reciprocal guiding and lateral holding of the distal hinge portion and of the telescope leg in the assembled position, to maintain a constant orientation thereof. relative to each other, the releasable axial retaining means provide the reciprocal axial retention of the distal hinge portion and the bezel leg, to maintain them in the assembly position, the axial retaining means releasable means comprise release means allowing the user to separate by axial traction the bezel branch away from the distal portion of the tank Niere.

  In the description and the claims, the term "distal" designates an element relatively remote from the face of the telescope, and the term "proximal" designates an element relatively close to the face of the telescope.

  By the simultaneous presence of longitudinal embedding means and releasable axial retaining means, the device can provide a satisfactory mechanical support while being of a small volume and insensitive to wear.

  According to an advantageous embodiment, the longitudinal embedding means comprise: - an axial shaft provided on the distal hinge portion, - an axial housing provided on the proximal end of the bezel branch and shaped to receive longitudinally sliding the handle axial hinge.

  By the presence of the axial shaft on the distal hinge portion, and by the presence of the axial housing in the bezel branch, it is possible to design such a device in which the axial housing has a relatively large length along the bezel branch, promoting the mechanical assembly of the bezel branch on the bezel face, while avoiding increasing the weight of the bezel face, for a better user comfort.

  Preferably, the axial shaft and the axial housing have a non-circular cross section, opposing the relative axial rotation of one with respect to the other. For example, the axial shaft may have a rectangular cross section, and its longitudinal edges may engage in corresponding longitudinal grooves of the axial housing. This ensures, in a simple manner, the locking in axial rotation of the bezel branch relative to the bezel face, for a better holding of the bezel during use by the user.

  According to an advantageous embodiment, the releasable axial retaining means comprise an element with transverse elastic deformation capacity, for elastically engaging in a lateral retaining housing in the assembly position, and for retracting elastically during the relative axial sliding of the bezel branch and the distal hinge portion for assembly or separation. This facilitates the use of the assembly device, assembly and separation can be provided by a simple axial force of the user between the bezel face and the bezel branch. According to a first embodiment, the element with transverse elastic deformation capacity is an elastically flexible axial rod, developing from the distal end of the axial shaft, fixed to the distal hinge portion by crimping, gluing or welding, and engaging in a corresponding distal section of the axial housing of the telescope branch. A particularly simple structure is thus produced.

  In practice, the elastically flexible axial rod may comprise a curved section or oriented away from the longitudinal axis of the bezel branch so as to engage in the lateral retaining housing by a distal boss or by an intermediate boss. The structure is thus particularly simple.

  Alternatively, the elastically flexible axial rod may advantageously be an open half-loop, comprising a first direct axial section developing from the distal hinge portion towards the telescope branch, then connected by a bend to a second axial section. return device developing towards the distal hinge portion, with a lateral boss provided on the return section for engaging the lateral retaining housing. This embodiment may be preferred, insofar as it increases the elastic capacity of the axial rod, for a more smooth and reliable operation of the assembly device.

  Preferably, to facilitate the adaptation of the telescope leg to the face of the telescope, it will be provided that the axial housing of the telescope arm comprises a longitudinal guide groove in which at least a portion of the elastically flexible axial rod slides during its introduction. This arrangement provides guidance in orientation of the telescope branch relative to the face of the telescope.

  To further improve the ease of use, particularly for the separation of the telescope leg with respect to the face of the telescope, it can be provided that the lateral retaining housing is through. In this case, it will preferably be chosen that the lateral retaining housing is provided in the inner wall 4594DEP 2875609 4 or in the lower wall of the axial housing of the telescope branch, and opens on the inner face or on the lower face of the branch of the telescope. glasses.

  The user can thus act on the boss, through the lateral retaining housing, to disengage the element with transverse elastic deformation capacity and thus be able to separate the bezel branch away from the bezel face by axial traction. of reduced value.

  In the case of a lateral retaining housing which passes through the bezel branch wall, it may be preferred to dispose said lateral housing either in the inner wall or in the lower wall of the axial housing of the telescope leg, in order to avoid alter the aesthetic appearance of the bezel branch.

  Other objects, features and advantages of the present invention will emerge from the following description of particular embodiments, with reference to the attached figures, in which: FIG. 1 is a front view of a telescope according to a embodiment of the present invention; - Figure 2 is a top view of the bezel of Figure 1; Figure 3 is an exploded side view of an assembly device according to an embodiment of the present invention; FIG. 4 is an exploded top view of the device of FIG. 3; - Figure 5 is a side view of the device of Figure 3 in the assembled state; - Figure 6 is a top view of the device of Figure 3 in the assembled state; FIG. 7 is a side view on a larger scale of the assembly device of FIG. 3; FIG. 8 is a view from above showing the hinge zone of the device of FIG. 7; - Figure 9 is a top view in longitudinal section along the plane 1-I of Figure 7; - Figure 10 is a cross section along the plane A-A of Figure 9; - Figure 11 is a cross section along the plane B-B of Figure 9; and - Figure 12 is a cross section along the plane C-C of Figure 9.

  FIGS. 1 and 2 are firstly considered, representing a bezel provided with assembly devices according to the present invention. Traditionally, the bezel comprises a bezel face 1 and two bezel branches 2 and 3 which are articulated to the bezel face 1 by a respective hinge 4 or 5.

  Each hinge, for example hinge 4, comprises a proximal hinge portion 4a and a distal hinge portion 4b hinged to each other 454DEP 2875609 in a vertical axis of rotation 4c such as a screw engaged in respective holes of the proximal portion 4a and the distal portion 4b of hinge.

  The proximal hinge portion 4a is associated with the bezel face 1, to which it is connected for example by a pin 6, while the distal hinge portion 4b is associated with the corresponding bezel branch 2. In practice, in the usual way, the proximal hinge portion 4a, integral with the bezel face 1, comprises a plate engaged and guided in a yoke of the distal hinge portion 4b.

  The invention provides assembly devices 7 and 8 respectively between the bezel face 1 and the bezel branches 2 and 3, assembly devices that allow the user to easily assemble the bezel branches 2 and 3 on the bezel face 1 and easily separate the bezel branches 2 and 3 away from the bezel face 1.

  FIGS. 3 to 6, which illustrate the assembly device 7, are now considered.

  We distinguish again the proximal hinge portion 4a secured to the pin 6 and pierced with a hole 4d for the passage of the screw 4c (Figure 6). There is also the distal portion of hinge 4b, in the form of a clevis receiving low clearance plate of the proximal hinge portion 4a, and pierced with two holes 4e for the passage of the screw 4c. The distal hinge portion 4b is intended to be assembled to the bezel branch 2 by the assembly means according to the invention.

  In the embodiment illustrated in FIGS. 3 to 6, the assembly means comprise longitudinal embedding means, comprising an axial shaft 9 provided on the distal hinge portion 4b, and an axial housing 10 provided on the end proximal to the telescope branch 2.

  The axial housing 10 is shaped to receive longitudinally sliding 11 axial hinge sleeve 9, the longitudinal direction being the elongation direction of the bezel branch 2.

  The assembly device according to the invention further comprises releasable axial retaining means, comprising, in the embodiment illustrated in Figures 3 to 6, an elastically flexible axial rod 12, which develops from the distal end of the axial shaft 9, which is attached to the distal portion of hinge 4b, and which engages in a corresponding distal section of the axial housing of bezel branch 10.

  FIGS. 5 and 6 show the axial shaft 9 engaged in the proximal part of the axial housing of the telescope arm 10, and the elastically flexible axial rod 4594DEP 2875609 12 engaged in the distal section of the axial housing of the telescope arm 10 .

  The proximal end of the resiliently flexible axial shaft 12 is attached to the distal hinge portion 4b by any suitable attachment means, for example by crimping, gluing, welding.

  To provide the releasable axial retention function, the axial retaining means, such as the elastically flexible axial rod 12, comprises a member with a resilient transverse deformation capacity for resiliently engaging in a lateral retaining housing 13 provided in the wall. In this way, the element with transverse elastic deformation capacity can, in the assembly position illustrated in FIGS. 5 and 6, engage resiliently in the lateral retaining housing 13. On the other hand, element with transverse elastic deformation capacity can retract elastically during the relative axial sliding of the bezel branch 2 and the distal hinge portion 4b according to the arrow 11 for assembly or separation.

  In the case of an elastically flexible axial rod 12, there is provided, on the elastically flexible axial rod 12, a boss 12a which constitutes the element which is resiliently engaged in the lateral retaining housing 13 in the assembly position ( Figure 6).

  In the embodiment illustrated in FIGS. 3 to 6, and also illustrated on a larger scale in FIGS. 7 to 9, the axial rod 12 is an open half-loop, comprising a first direct axial section 12b developing from the distal portion of FIG. hinge 4b in the direction of the bezel branch 2 and then connected by a bend 12c to a second axial return portion 12d developing towards the distal hinge portion 4b, the lateral boss 12a being provided on the return section 12d for engage in lateral restraint housing 13.

  The longitudinal embedding means, comprising the axial shaft 9 and the axial housing 10, provide guidance and mutual lateral support of the distal hinge portion 4b and the bezel branch 2 in the assembly position, to preserve a constant orientation with respect to each other.

  The releasable axial retaining means, comprising the elastically flexible axial rod 12 with its boss 12a engaging in the lateral retaining housing 13 in the assembly position, provide mutual axial retention of the distal hinge portion 4b and the limb of bezel 2, to keep them in the assembly position.

  Furthermore, it can be provided that the releasable axial retaining means comprise release means, to enable the user to voluntarily and more easily separate the telescope branch 2 away from the distal portion of the telescope by axial traction. hinge 4b. For this, according to one embodiment of these release means, it is possible to give the boss 12a a rounded shape, for example as illustrated in the figures, allowing the axial sliding of the elastically flexible axial rod 12, the boss 12a. being pushed towards the longitudinal axis of the bezel branch 2 against the elastic restoring force exerted by the elastically flexible axial rod 12, during a traction force of sufficient value exerted by the user between the limb 2, and the bezel face 1. Such a rounded boss may be suitable for engagement in a blind, non-through, lateral retention housing 13.

  Similarly, the symmetrical rounded shape of the boss 12a facilitates the axial engagement of the elastically flexible axial rod 12 when it is introduced into the axial housing 10 of the telescope branch 2.

  To ensure a good mutual maintenance of the distal hinge portion 4b and the bezel branch 2 in the assembly position, the axial shaft 9 is received in the axial housing 10 in force or at low clearance. The axial length of the axial shaft 9 is chosen sufficient to take up the bending forces between the distal hinge portion 4b and the bezel branch 2.

  FIG. 12 illustrates in cross-section along the plane CC of FIG. 9 the embedding between the axial shaft 9 and the axial housing 10 provided in the telescope branch 2, and the proximal end 12e of the axial rod is seen resiliently flexible 12 which is fixed in the axial shaft 9 of the distal hinge portion 4b.

  In FIG. 10, in cross-section along the plane A-A of FIG. 9, the distal end region of the elastically flexible axial rod 12 is engaged with a small clearance in the circular-section distal portion of the axial housing 10.

  An improvement in the ease of assembly between the distal hinge portion 4b and the bezel branch 2 is ensured by providing means for guiding the elastically flexible axial rod 12 in the proximal portion of the housing 10. In this respect, it is possible to refer again to FIG. 12. It can be seen that the elastically flexible axial rod 12 can engage laterally in a longitudinal guide groove 14 provided in the wall of the bezel branch 2, opposing the relative rotation between the elastically flexible axial rod 12 and the bezel branch 2 during the axial relative translation movement for the assembly.

  In FIG. 11, illustrating a cross-section along the plane BB of FIG. 9, we see the boss 12a engaged in the housing 13 in the wall of the telescope branch 2. In this embodiment, the housing 13 opens on the inner face 2a of the bezel branch 2, or face intended to be oriented towards the head of the user. Alternatively, it could be provided that the lateral housing 13 is in the lower face 2b of the telescope branch 2.

  We also see, in this embodiment, that the lateral retaining housing 13, which opens on the inner face 2a of the bezel branch 2, allows the user to push with the finger or with a tip the boss 12a towards the inside, to facilitate the axial sliding of the bezel branch 2 relative to the bezel face 1. A second release means is thus produced.

  The rounded shape of the boss 12a and / or the emergent shape of the lateral retaining housing 13 constitute release means which, separately or in combination, allow the user to easily separate by axial traction the bezel branch 2 away of the distal hinge portion 4b, while ensuring a good behavior of the bezel branch on the face of the bezel.

  The axial shaft 9 and the axial housing 10 have a cross section of non-circular shape that opposes the relative axial rotation of the bezel branch 2 relative to the bezel face 1. In practice, the axial shaft 9 has a rectangular cross section, and four longitudinal edges which engage in four corresponding longitudinal longitudinal grooves 10a, 10b, 10c and 10d provided in the wall of the axial housing 10. The longitudinal grooves 10a and 10b are deeper and join to form a generally rectangular guiding groove 14 in which a side 9a of the axial shaft 9 engages.

  To achieve the assembly device in a small volume, it can be advantageously provided that the elastically flexible axial rod 12 is made of metal, preferably stainless steel which has been treated to give it satisfactory properties of elasticity. As illustrated, the resiliently flexible axial shaft 12 may be formed by folding a round wire.

  Fixation of the elastically flexible axial rod 12 in the distal hinge portion 4b may advantageously be provided by crimping, so as to avoid any heating that may degrade the elastic properties of the elastically flexible axial rod 12.

  The bezel branch 2 may advantageously be made of titanium, providing good rigidity of the wall surrounding the axial housing 10.

  4594DEP 2875609 9 However, it is possible to provide a plastic bezel branch 2, provided that a sufficiently rigid plastic material is chosen, or by providing a metal insert providing the axial housing 10.

  The present invention is not limited to the embodiments which have been explicitly described, but includes the various variants and generalizations thereof within the scope of the claims below.
