Description

New spectacle arm mounting system

The present invention relates to a new mounting system for a spectacle arm and spectacles provided with such a system.

In the field of eyewear, we have always dealt with aesthetic issues. Increasingly, spectacle wearers use several different pairs depending on the circumstances, for example work, sport, evening, etc.

After lengthy research, the applicant discovered a new mounting system for a spectacle branch, which is aesthetic and which makes it possible to change the branches of glasses at will, easily and without tools.

This system can also make it possible to install wired branches. In what follows, the positions of the elements are given with reference to the usual wearing of glasses on the face of the wearer of said glasses in a standing position.

The subject of the present application is a new mounting system for a spectacle branch, and spectacles or spectacle elements provided with such a mounting system.

This is why the first object of the present application is glasses characterized in that they comprise a system for mounting a branch of glasses comprising a branch mounting screw installed approximately horizontally, and preferably approximately perpendicular or approximately parallel to the "plane. "of a lens, and whose thread, directed towards the outside of the lens when the branch mounting screw is installed approximately parallel to the" plane "of a lens, is free to cooperate with a nut.

Under preferential conditions for implementing the invention, the branch mounting screw is installed approximately parallel to the "plane" of a lens and the thread of the branch mounting screw directed towards the outside of the lens is projection on the edge of the frame, or the edge of the lens for glasses without rim.

In other preferential conditions for implementing the invention, the branch mounting screw is installed approximately perpendicular to the "plane" of a lens and towards the rear and the thread of the branch mounting screw protrudes from the frame, or the lens for glasses without strapping.

The projection may for example be between 1 and 10 mm, in particular between 2 and 8 mm, and very particularly between 3 and 6 mm.

In the present invention, the term "branch" means both a "conventional" branch of the rigid or semi-rigid type (that is to say which can be bent without breaking it) as well as a wire branch. "Glasses without rim" means glasses in which the mounting of the arms is done directly on the glass, without total or partial rim of the glass as opposed to rim or semi rim rim where the glass is surrounded by a frame for example made of metal and / or plastic and a wire for semi-rimmed.

Under preferential conditions for implementing the invention, the branch mounting screw is diametrically split over at least part of its length for the reasons explained below, the slot preferably being provided vertical or in particular horizontal.

In other preferred conditions for implementing the invention, the above mounting system further comprises a second screw called a "mounting screw on a glass". When the branch mounting screw is installed approximately parallel to the "plane" of a lens, the second screw is advantageously installed approximately at right angles to the branch mounting screw and perpendicular to a lens. The two screws can also be provided in alignment with each other.

The second screw can be used to mount the system directly on a spectacle lens.

The above mounting system preferably comprises a rod installed substantially parallel to the mounting screw on a glass, to cooperate with a notch provided on the edge of the glass or with an orifice produced by drilling the glass. Thus the mounting system is kept in position without the possibility of rotation.

The branch mounting screw is advantageously diametrically split as will be seen below.

It preferably has the structure of two coaxial cylinders of different diameter, the cylinder of smaller diameter being threaded to constitute (a screw while the second screw is advantageously fixed on the cylinder of larger diameter. The cylinder of larger diameter can be truncated to press against the glass, which shows that this form of cylinder is purely optional. branch assembly and the second screw can constitute a single piece, the two screws can then for example be welded perpendicular to each other, preferably to form an L, or aligned.

They can be separate. In this case, the branch mounting screw is diametrically perforated to allow the passage of the second screw, and their mounting is preferably at right angles. The branch mounting screw can be installed in front of or behind the glass.

Under preferential conditions of implementation, the two screws are mounted one at the end of the other. In the case of ringed mounts, the branch mounting screws according to the invention constitute studs installed on the face of the glasses. The studs can be fixed to the face of the frame by any known means, screwing, riveting, gluing, welding, mass casting, etc.

The branch mounting screw is used for mounting a branch of a particular type. Said particular branch comprises a nut in particular of the wheel type mounted in free rotation with respect to said branch, said nut being designed to cooperate with the thread of the branch mounting screw.

In a first preferred configuration, the branch is a wired branch, that is to say comprising a wire or mainly consisting of a wire for example of polyester, nylon, metal with a diameter less than 0.3 mm in diameter that is to say behaving almost like a textile, elastomer or rubber thread, that is to say stretch. The wire branch therefore joins a glass of glasses to the other, surrounding the head. The nut can then have the configuration of an internally threaded sleeve and one end of which is practically closed, however leaving the passage for the wire, the end of which on the side of the sleeve has an enlarged part to block in the sleeve leaving however it is free to rotate. An elastic wire branch is particularly suitable for the practice of sports if it sticks the pair of glasses on the figure. It is advantageous to combine a branch part of the rigid or semi-rigid type with a branch of the wire type, in particular extendable.

The part of branch of rigid or semi-rigid type can be between two linear parts and in this case it is advantageously curved to adapt to the turn of the skull or the neck or vice versa.

In another preferred configuration, the branch is of the rigid or semi-rigid, that is to say conventional, type. The central axis of said nut is then preferably installed perpendicular to the branch. The end of the branch on the side of the glasses advantageously comprises two returns at right angles, said nut being installed at the level of the first return as illustrated below in the figures, or a single return extended by a flattened tip with a spatula.

The returns at right angles are preferably made of a rigid or semi-rigid metal wire. Under preferential conditions of implementation, the entire branch is made up of a wire, for example metallic, with a diameter in particular of around 1 mm, which considerably simplifies the manufacture of the branch, preferably made of titanium. It goes without saying that part of the wire can be sheathed, for example at the ears.

In yet other preferential conditions of implementation, the length of the first return corresponds substantially to the length of the sleeve constituting the nut.

In always other preferential conditions of implementation, the length of the second return is approximately 0.5 to 8 mm, advantageously between 0.5 and 5 mm, preferably between 1 and 5 mm, in particular between 1 and 3 mm.

In always other preferential conditions of implementation, the branch, conventional or not, is pivotally articulated on a pivoting part comprising a flattened rod at its end opposite to the pivot axis, said rod being surrounded by a thumbscrew as above. This piece can measure for example from 4 mm to 10 mm long. The pivoting part advantageously consists of a ring and a blade, connected by a rod. The rod is surrounded by an internally threaded sleeve. The center of the ring constitutes the pivot axis of the branch to close it against the face and the blade is designed to fit into the slot of a mounting screw of plugged. The branch can be conventionally mounted on the pivoting part by means of a screw or a rivet.

The installation of a spectacle branch by means of a branch mounting system according to the invention can be carried out very easily. In the case of a wired branch, it suffices to screw the internally threaded bush onto the branch mounting screw. In the case of a rigid or semi-rigid branch, it suffices to introduce the second return or the blade into the slot of the second screw described above and to screw the socket onto said mounting screw. It is obvious to those skilled in the art that the slit and the second return must be oriented so that the spectacle branch is installed horizontally.

In other preferential conditions for implementing the invention, the nut is externally cylindrical, which facilitates its screwing and unscrewing by hand, without instrument, by the wearer of glasses. To avoid sliding of the fingers during screwing or unscrewing, there is advantageously provided on the outer surface of the nut with a non-slip treatment, for example by installing diamond points or other reliefs such as a knurling wheel.

In still other preferential conditions for implementing the invention, the outside diameter of the nut is substantially identical to or slightly greater than that of the cylinder with the largest diameter of the screw when such a cylinder is provided, to facilitate unscrewing it without being hindered by said screw.

In still other preferential conditions for implementing the invention, the spectacle arm mounting system according to the present invention further comprises a protuberance opposite the screw for mounting spectacle lenses. This protuberance can be cylindrical, but advantageously ovoid.

It allows the mounting on a pair of glasses of a screen, for example a tinted screen.

Such a screen is for example made of a plastic film such as cellulose acetate whose shape substantially matches that of spectacle lenses, said screen comprising lateral perforations including the spacing corresponds to that of the protrusions and allowing passage and blocking of the protrusions.

It is thus sufficient to align the perforations and the protrusions and to push the screen in the direction of the glasses in order to obtain, for example, sunglasses the mounting of which is not hampered by any device since it benefits from the already existing device for mounting the glasses and their arms.

The present application also relates to the new mounting system for the spectacle arm described above. This is why the subject of the present application is a new mounting system for a spectacle branch, in particular for glasses without rim, characterized in that it comprises a screw installed approximately horizontally and approximately parallel to the "plane" of a lens, and whose thread, directed towards the outside of the glass, is free to cooperate with a nut and is protruding on the edge of the glass.

The present application finally relates to a branch of glasses, characterized in that it is of rigid or semi-rigid type, in that its end on the side of the glasses comprises two returns at right angles, a nut mounted in free rotation around of the branch being installed at the level of the first return and in that the central axis of said nut is installed perpendicular to the length of the branch as well as a branch of spectacles, characterized in that it is wired and in that it comprises a nut which has the configuration of an internally threaded sleeve, and one end of which is practically closed in. however, leaving the passage for the wire, the end of which on the side of the socket has an enlarged part to block in the socket, however leaving the latter free to rotate.

The pairs of glasses object of the present invention have very interesting qualities. The wearer of the glasses according to the invention can in particular change the system of branches at will according to the activities which he practices. He can thus have glasses whose frame is perfectly adapted to all circumstances and all places. Likewise, the temples can be changed at any time by the user of the glasses, who can thus have several frames for a single set of lenses, and this without dismantling equipment.

The preferential conditions for implementing the pairs of glasses described above also apply to the other objects of the invention referred to above, in particular to the mounting systems and to the branches of glasses according to the invention.

The invention will be better understood if reference is made to the appended drawings in which

FIG. 7 represents a pair of glasses, the branches of which essentially consist of a textile thread.

FIG. 8 represents a branch installed on a face of the telescope, seen from above.

Figure 9 is a side view of a tenon for a branch according to the invention.

FIG. 10 is a top view of a pivoting part for a branch and FIG. 11 is a side view of this part. In FIG. 1, a glass 1 can be seen laterally comprising a system for mounting a spectacle arm according to the invention in a single piece directly mounted on a glass. It is essentially an L-shaped screw, the two ends of which are threaded. The system consists of a branch mounting screw 2 and a second screw 3 for mounting on the glass. The opinion

2 of branch mounting is installed approximately horizontally and approximately parallel to the "plane" of a glass represented by AB. Its thread 4 is directed towards the outside of the glass, and is free to cooperate with a nut. It is indeed protruding on the edge of the glass. The mounting system shown also includes a second screw

3 installed approximately at right angles to the branch mounting screw 2 and perpendicular to the glass 1. This second screw 3 passes through the glass 1 which is held by a conventional nut 5.

The system further comprises a rod 6 installed substantially parallel to the screw 3 for mounting on the glass 1, to cooperate with a notch 7 provided on the edge of the glass 1. Thus the mounting system is held in position without the possibility of rotation.

In Figure 2 we can observe the assembly of a two-piece system. The screws 2 and 3 are indeed two separate parts. The branch mounting screw 2 is radially perforated to allow passage of the mounting screw 3 on the glass 1. This screw 3 has a conventional structure. It has a non-threaded cylindrical end 8 enlarged relative to the diameter of the thread.

In Figure 3, there is a conventional frame 9 strapping. The branch mounting part 10 is provided with a branch mounting screw 2 projecting from the edge of the frame 9.

FIG. 4 is a variant of FIG. 1 in which the branch mounting screw 2 is diametrically split 11 over part of its length in order to better cooperate with the branch shown in FIG. 6.

FIG. 5 is another variant of FIG. 1 in which the branch mounting screw 2 comprises a ball-shaped protrusion 12 allowing the mounting on the pair of glasses of a screen 13 made of a film tinted with 0, 5 to 1 mm thick, the shape of which matches that of the glasses and which is pierced at the level of the protrusions 12 so that it can be pressed in and thus become blocked and remain pressed against the glasses. In FIG. 6, the end situated on the side of the glasses of a branch 14 essentially consisting of a flexible metallic wire, that is to say semi-rigid, made of titanium 1 mm in diameter sheathed with plastic material. The end of the branch on the side of the glasses includes two returns 16, 17 at right angles. A nut 18 in the form of a socket, threaded internally, is installed at the level of the first return 16. The length of the first return 16 corresponds substantially to the length of the socket 18 constituting the nut, which blocks the latter in the longitudinal direction. . The diameter of the metal wire 15 is less than that of the thread to leave the bushing 18 free to rotate around the metal wire 15. The length of the second return 17 is approximately 4 mm.

The installation of a spectacle branch on a branch mounting system according to the invention can be carried out very easily: it suffices to introduce the second return 17 into the slot 11 of the branch mounting screw 2 shown in the Figure 4, align the sleeve 18 and the branch mounting screw 2 and finally screw the bushing 18 onto said mounting screw 2. It can be observed that the slot 11 is oriented so that the second return 17 of the branch 14 of glasses should be installed perpendicular to the plane formed by the first return 16 and the branch 14 so that the latter is in the normal horizontal position. It can also be observed that the nut 18 is externally cylindrical, which facilitates its screwing and unscrewing by hand, without instrument, by the wearer of glasses. Its outer surface has diamond points 19.

The outside diameter of the sleeve 18 is substantially identical to or slightly greater than that of the non-threaded cylindrical end 8 to facilitate its unscrewing without being hindered by the screw 2. Such a characteristic is more aesthetic, which is important for glasses .

FIG. 7 represents a pair of glasses, the branches 14 of which essentially consist of textile threads 20, 21 which can for example be decorated with threaded beads. A third elastic thread 22 is provided. The sockets 18 are mounted in free rotation on the textile threads 20, 21 so that they can be screwed onto the branch mounting screws 2. It should also be noted that, taking into account the possibilities of twisting the strands, it is not essential that the sockets 18 are mounted in free rotation. The online assembly of the three wires is made according to the same principle of the bolt. It is observed that the external diameter of the sockets 18 is identical to the diameter of the non-threaded part of the screws with which they cooperate, which also produces an excellent aesthetic effect.

In FIG. 8, there is a branch 14 mounted on a face of glasses 9 thanks to a pivoting part 23 and to a nut 18. The screw 24 ensures the mounting of the branch on the pivoting part 23, of which it constitutes the pivot axis. . The branch mounting screw 2 of the type shown in FIG. 9 is installed approximately horizontally (and therefore parallel to the spectacle branch), and approximately perpendicular to the "plane" of a lens; screw 2 is hidden by nut 18.

In FIG. 9, we can distinguish the structure of the post on which the branch of FIG. 8 is installed. This comprises a fixing plate 25 making it possible to install the post on the face of glasses, for example using of screws, as shown in FIG. 8. This tenon essentially comprises a branch mounting screw 2 comprising a slot 11. In a version for use for glasses without strapping, a second screw is provided, on the other side of the plate 25 and in the same direction or a parallel direction for direct mounting on a glass.

FIG. 10 makes it possible to observe the particular structure of the pivoting part 23. This consists of a ring 26, intended to be crossed by the screw 24, and a spatula 27, connected by a rod 28. The spatula 27 can be inserted into the slot 11 of the post. The socket 18 has not been shown. For an assembly like that of FIG. 8, the slot 11 of the branch mounting screw 2 has been provided horizontal. Figure 11 shows the same elements.
