Abstract

The spectacles, consisting of lenses (6), side pieces (4) and connectors (10) with free ends (20) inserted through holes (30) in the lenses and fitted with nuts (48), has each fixing equipped with a shock absorbing cushion (34) between it and the lens and a flexible washer (54) between the lens and nut. Each cushion has a projecting tip (42) which fits in the lens hole and has an aperture (44) through it for the fixing. An outer wing (38) on the cushion fits between the lens edge and an outer part (18) of a U-shaped portion of the fixing.

Description

The present invention relates to the technical field of spectacles.

Conventionally, glasses comprise two branches, two glasses, and ion organs, to connect each branch to each glass, or the two glasses together. More specifically, provided first and second connecting members, called tenons, which are articulated to the branches and are fixed by their free ends to a corresponding glass. A third connecting member, called bridge, is fixed by its two free ends on each glass.

Known from US-A-5,835,183, a device for fixing, on a corresponding glass, each free end one of the aforementioned connecting members. Indeed, each connecting member has a U-shaped region, one free end of which penetrates into a hole of the glass.

Fixing between this end and the glass is made by elastic snap-fastening, since the U-shaped region is prestressed, so that the second flange, facing the free end, bears against the lateral face of the glass. Moreover, each free end is provided with teeth, allowing its frictional retention against walls of the glass bordering the aforementioned orifice.

This known device, however, has certain disadvantages. Indeed, it does not provide a sufficiently reliable fixation, insofar as significant constraints on the glasses are likely to cause a separation of the connecting members with respect to glasses. Moreover, this solution induces the formation of scratches on the glass, which is disadvantageous, not only in aesthetic terms, but also in terms of mechanical strength of the glasses.

In order to overcome these various drawbacks, the present invention proposes to make a pair of glasses, the lenses of which on the one hand only suffer from weak mechanical constraints, and are, on the other hand, secured in a satisfactory manner, either between themselves or with a corresponding branch. For this purpose, it relates to glasses comprising less a first pair of glasses, two branches connecting members for connecting or between the glasses between a branch with a corresponding glass, each connecting member having at least one penetrating fiber end at least partially in an orifice formed in glass, characterized in that at least one attached fastening means is provided for securing said free end with a corresponding glass in that at least one damping pad is provided. , interposed between the surface of the glass and the surface facing a corresponding connecting member.

According to other features of the invention - the fastening means are provided with a retaining collar against a front face of the glass - the retaining flange is separated from the front surface of the glass by means of a damping washer ; - The fastening means are fastening means by screwing, in particular a nut adapted to cooperate with a threaded stud of said end; each connecting member is provided with a U-shaped zone, each of said zones having a first wing extending in the vicinity of a notch formed in a lateral edge of the glass, close to said orifice, thus a second wing forming said free end; - The damping pad has an end portion fitted into said orifice, said end portion having a central opening passage of said free end; - The pad has a U-shape and comprises first wing interposed between said notch of the glass and said first wing of the U-shaped area, and a second wing forming said end portion; the damping pad is made of nylon; at least one pair of interchangeable additional glasses, the thickness of which is different from that of the first pair of glasses, is provided, and additional fixing means are also provided, the axial dimension of which is different from that of the first fixing means. .

The invention will be described below, with reference to the accompanying drawings, given solely by way of non-imitative examples and in which - Figure 1 is a perspective view of an eyeglass pair according to the invention; FIGS. 2 and 3 are perspective views, on a larger scale, partially illustrating the different constituent elements of two pairs of spectacles according to the invention, the lenses of which are of different thicknesses; - Figures 4 and 5 are views in longitudinal section, partially illustrating the two pairs of glasses of Figures 2 and 3, once mounted.

The spectacles represented in FIG. 1, generally designated by the reference 2, conventionally comprise two branches 4 and two lenses 6. Three connecting members are also provided, namely two pins 8 making it possible to join each lens together. 6 with a corresponding branch 4, and a bridge 10, to mutually secure the two glasses 6.

Each tenon 8, which has a filiform cylindrical cross section, is articulated at a first end 12 on a corresponding branch 4. This pin 8 has, opposite this end 12, a U-shaped zone 14, comprising a core 16 , as well as two wings 18 and 20. The wing forming the free end of the pin 8, is provided with a threaded nipple 22.

The bridge 10 comprises a threadlike median section 24, of cylindrical section, and two U-shaped zones 26, 28, whose profile is similar to that of the zone 14 of each pin 8, described above. Each glass 6 is pierced, in the vicinity of one of its lateral edges, with a through orifice. Moreover, each edge is hollowed out with a notch 32, extending parallel to the orifice 30, close to the latter. It should be understood that such a hole and such a notch are provided in the number of four, namely on the two side edges of each glass.

FIGS. 2 and 3 further illustrate a damping pad 34 intended to be inserted between the surface of a glass 6 and the facing surface of the connecting members, namely one of the abovementioned zones 14, 26, 28, in U shape.

Each pad 34, which is made of nylon, also has a U-shape, that is to say, it comprises a core 36, and two wings 38, 40. The wing 40, forming a tubular sheath, penetrates into the orifice 30 of one of the glasses 6 and has a shoulder 42, allowing the support against a front face of the glass considered. Moreover, this sheath 40 is hollowed out with a central opening 44, allowing the free end 20 to pass through one of the connecting members.

The 36 and the other wing 38 of the pad 34 have a groove 46, allowing the reception of the core 16 and the first wing 18 of the U-shaped zones which are provided with the tenons 8 and the bridge 10. Once mounted, as shown in particular in Figures 4 and 6, the wing 38 of the pad 34 is received in the lateral notch 32 of the glass 6.

FIGS. 2 and 3 also represent various means for fixing, by screwing, the free end 20 with respect to the glass 6. The first fastening means comprise a blind nut 48, hollowed out with a thread 50, itself bordered by a flange 52, whose diameter is greater than that of the orifice 30.

There is also provided a washer 54, made of nylon, whose diameter is close to that of the flange 52. The latter ensures the retention of the nut 48 relative to the surface of the glass 6, by pressing against the washer 54 , the latter coming for its part in abutment against the aforementioned surface of the glass.

As shown in FIGS. 3 and 5, an additional nut 48 'is provided, the axial dimensions of which are greater than those of the nut 48. For this purpose, the nut 48' comprises a cylindrical section 49 'provided with 'a tapping 50'. This section 49 'is extended by a flange 52' able to penetrate into the orifice 30 of the glass so as to be screwed on the threaded nipple 22.

Using such a nut 48 'makes it possible to fix the free end 14 on a glass <B> 61, </ B> whose thickness is greater than that of the glass 6, as illustrated in FIG. 4. The cylindrical section 49 'then enters the hole 30' household in this glass 6 '.

Figures 2 and 3 illustrate only two nuts of different sizes, but it should be understood that one can provide a larger number of such nuts, if we have several glasses of different thicknesses.

Figures 2 to 5 show only the detailed fixing of a pin 8 on a glass 6, 6 '. It should be noted that the fixing of the other stud on the other glass, as well as that of the bridge on the two glasses performed in a similar manner.

The invention makes it possible to achieve the aforementioned objecti. Use of reported fastening means gives great reliability to the mutual bonding of the glass and each connecting member. Such a fastening is particularly safe, in the case where fastening means are provided with a retaining flange against the surface of the glass. Moreover, the use of a damping pad makes it possible to reduce, to a large extent, the stresses exerted on the lenses by metal ends of the connecting members.

The use of different size fastening means is particularly convenient. Indeed it allows to use a single set of branches and connecting members, while allowing the reliable fixing glasses of different thicknesses.
