Description

"Spectacle frame with a deformable face on the nose".

 The subject of the invention is a spectacle frame of the type comprising a front frame with glass holder circles and provided, between these circles, with supports for deformable support elements on the nose.

 In spectacle frames, and in particular in spectacle frames which must be worn almost constantly by the user, it is important to reduce, as much as possible, the discomfort caused by the support of the glasses on the nasal appendage. of this user.

 Among the known technical solutions to overcome this drawback, a widespread solution consists in the adoption of support elements on the nose having elastically deformable plates.

 Thanks to the deformable nature of the plates, it is possible to obtain a certain adaptation of the shape of the support element on the nose, to the morphology of the nose of the user.

 These plates are provided with a button, a dowel or other connecting means arranged in an almost central position and which can be connected to suitable supports fixed to the glass holder circles of the frame.

 The support elements on the nose currently available only meet the conditions mentioned above if it is sufficient to deform the plates by giving them a convexity directed towards the nose of the user.

 In fact, if the plate has to adapt to small bumps in the nose, this plate can only ensure substantially punctual contact zones causing precisely the discomfort mentioned above.

 The invention aims to create a spectacle frame arranged to meet the conditions of minimum discomfort of the user by being able to adapt to any nose conformation.

 To this end, the invention relates to a spectacle frame of the type comprising a front frame with glass holder circles and provided, between these circles, with supports for deformable support elements on the nose, characterized in that each of the support elements on the nose comprises an elastically deformable plate and, a bar-shaped element whose ends are connected to the plate at two spaced points, this element being connected in an intermediate location to a corresponding support disposed on the carrier circle -glass.

Other characteristics and advantages of the invention will emerge below and the accompanying drawings in which
- Figure 1 is a partial view of a front frame of spectacle frame according to the invention, the support elements on the nose and the corresponding supports being shown in longitudinal section;
- Figure 2 is an exploded perspective view of a support element on the nose of the frame of FIG. 1;
- Figure 3 and Figure 4 are exploded perspective views showing two alternative embodiments of details of the support elements on the nose according to the invention.

 With particular reference to FIG.

1, the spectacle frame shown comprises a front frame 1 provided with two glass holder circles 2a, 2b connected by a cross member 4. Each glass holder circle is provided with a support, 3a and 3b respectively, anchored in the circle corresponding in an area below the cross 4.

Each support has a free end in the form of buttonholes, these ends being designated respectively by 5a and 5b.

 Each support 3a, 3b carries a support element on the nose designated as a whole by 6a, 6b.

These support elements allow the glasses to rest on the user's nasal appendage. This nasal appendage is indicated by a dashed line 7 in FIG. 1. Each support element on the nose comprises a plate 8 spreads mainly in the longitudinal direction and a bar-shaped element 9 whose opposite ends 10a, 10b are hinged to the plate 8 at two points on this spaced plate in the longitudinal direction.

 The bar-shaped element 9 comprises, in its intermediate part, a button 11 intended to ensure its assembly with the associated buttonhole 5a, 5b of the corresponding support 3a, 3b.

 The strip-shaped element 9 is produced from an elongated strip of elastically deformable material, for example spring steel, the ends 10a, 10b of this strip being folded in the form of a hook. Each end 10a, 10b engages in a corresponding housing 12a, 12b of the plate 8.

 The housings 12a, 12b are in the form of elongated cavities formed on the face of the wafer 8 situated opposite the nasal appendage 7, these cavities opening onto opposite ends of the wafer 8.

 Each housing 12a, 12b is traversed in transverse direction by a spacer 13a, 13b provided for removably engaging in the hooked folded ends 10a, 10b of the bar-shaped element 9.

 FIG. 3 represents a first guarantee for producing the bar-shaped element. In this figure, the element is designated as a whole by the reference numeral 20 and has opposite ends designated generally by 21a and 21b. In an intermediate position, substantially in the middle, the element com carries two legs 22a, 22b extending parallel to each other and perpendicular to the bar-shaped element. Holes 23 are made in the legs 22a, 22b.

 Still in accordance with FIG. 3, the support 24 comprises at its free end a buttonhole in the form of a boot 25 comprising holes 26 corresponding to the holes 23 of the bar-shaped element. The holes 26 and the holes 23 are traversed by a screw 27 which, by being fixed on the box-shaped buttonhole, constitutes an axis of articulation for the bar-shaped element 20.

 FIG. 4 represents a second variant in which there is provided a bar-shaped element 30 comprising an intermediate button 31 forming a loop, and a box-shaped buttonhole 32 disposed on the support 33. Holes 34 are formed in the button nière 32. A screw 35 also plays the role of articulation axis for the bar-shaped element 30 by crossing the holes 34 and the loop of the button 31.

 The assembly of the support element on the nose according to the invention is carried out by deforming the plate 8 so as to bring the longitudinal ends thereof.

 The ends 10a, 10b of the bar-shaped element are then introduced into the housings 12a, 12b so that the spacers 13a, 13b are placed in a position between the ends 10a, 10b mentioned above.

 The plate is then released and the spacers engage in the hook-shaped ends by making a hinged articulated connection with these ends.

 The bar-shaped element is thus linked to articulation at two points spaced from the plate.

 The button 11 is then pressed to engage it in the buttonhole 5a, 5b of the corresponding support 3a, 3b. The assembly between the button and the buttonhole provides an articulated link between the support element on the nose and the corresponding support.

 I1 is advantageous that in the spectacle frame according to the invention the support elements on the nose can adapt to any form of nasal appendage, either with a concavity, or with a convexity directed towards the nasal appendage of the user.
