Description

FIELD OF THE INVENTION The present invention relates to the field of assembly of a pair of spectacles. Subsequently, pairs of glasses are understood to be both pairs of sunglasses, sight or fantasy.

Conventionally, a pair of glasses consists of a spectacle frame in which lenses of different natures are mounted. The spectacle frame comprises a main frame, comprising two openings adapted to receive said glasses, and two branches mounted at the lateral ends of said main frame.

Given the increase in the number of people equipped with pairs of glasses, manufacturers are making constant efforts to offer original pairs of glasses. For this purpose, it has been proposed a spectacle frame whose side branches can receive a removable decoration shell. Thus, a user can select the decoration shell in accordance with the style of his clothes or his mood. Such removable decorative shells do not significantly alter the visual appearance of the spectacle frame since the main frame remains unchanged. Also, in practice, the suppliers of pairs of glasses offer a wide variety of eyeglass frames to meet the needs of their customers. Nevertheless, such a variety increases the cost of manufacturing a spectacle frame, which has a disadvantage. In addition, when a user's view changes over time, the user must change his eyesight. For this purpose, it can either change the mount or use an optician to proceed to the changes of glasses. Indeed, the assembly / disassembly of the lenses of a frame is a delicate operation during which it is necessary to deform the frame, generally by heating, in order to mount the lenses in force. In all cases, changing sight glasses entails additional costs at the intrinsic cost of the lenses, which has a disadvantage. The invention therefore aims to remedy at least some of these disadvantages by providing a customizable spectacle frame and the manufacturing cost is limited.

PRESENTATION OF THE FIGURES The invention will be better understood on reading the following description, given solely by way of example, and referring to the appended drawings, in which: FIG. 1 is an exploded diagrammatic representation of a spectacle frame according to the invention; Figure 2 is a close-up view of the central attachment portion of the lower member of the main frame of the spectacle frame of Figure 1; FIG. 3 is a close-up view of the left-hand side fixing part of the upper member of the main frame of the spectacle frame of FIG. 1; and - Figure 4 is a side view of another method of attachment of a side branch. It should be noted that the figures disclose the invention in detail to implement the invention, said figures can of course be used to better define the invention where appropriate. DESCRIPTION OF ONE OR MORE EMBODIMENTS AND IMPLEMENTATION With reference to FIG. 1, there is shown a spectacle frame 1 according to a preferred embodiment of the invention. The frame 1 is suitable for receiving any type of glasses, that is to say, both solar glasses, sight that fantasy. Subsequently, the terms "left" and "right" are defined according to the wearing of the eyeglass frame by a user having a right eye and a left eye. The spectacle frame 1 is presented in an orthogonal reference (X, Y, Z) in which the X axis extends horizontally from the right to the left, the Y axis extends vertically from the bottom to the top and the Z axis extends from front to back.

Still with reference to FIG. 1, the eyeglass frame 1 comprises a main frame 3 defining a left housing 7G and a right housing 7D able to receive respectively a left and a right lens (not shown). The main frame 3 further comprises a left side end 3G and a right side end 3D. In addition, the spectacle frame 1 comprises a left lateral branch 2G and a right lateral branch 2D which are respectively mounted at the left-hand lateral end 3G and at the right-hand lateral end 3D of the main frame 3. Preferably, the lateral branches 2G, 2D are removable from said main frame 3.

The main frame 3 and the lateral branches 2G, 2D can be made in any type of material, in particular colored plastic. Preferably, the main frame 3 and the lateral branches 2G, 2D are molded by plastic injection.

As illustrated in Figure 1, the main frame 3 consists of a lower member 31 and an upper member 32 to form a main frame 3 which is adjustable. Thus, advantageously, one can have a collection of lower members 31 and a collection of upper members 32 to form a main frame 3 whose appearance is personalized. Such a main frame 3 significantly impacts the aesthetic appearance of the spectacle frame 1, which is very advantageous. In this example, the left lateral branch 2G and the right lateral branch 2D are respectively mounted at the left lateral end and at the right lateral end of the upper part 32 of the main frame 3.

With reference to FIG. 1, each member 31, 32 of the main frame 3 comprises a right fixing part 31a, 32a, a right housing part 31b, 32b, a central fixing part 31c, 32c, a left housing part 31d , 32d, a left fixing portion 31e, 32e, the fixing portions 31a, 31c, 31e of the lower member 31 respectively being complementary in shape to the attachment portions 32a, 32c, 32e of the upper member 32. The parts central 31c, 32c form the central bridge of the main frame 3 which separates the left housing 7G and the right housing 7D as shown in Figure 1.

Due to their complementarity of shapes, the fastening portions 31a, 31c, 31e of the lower member 31 and the fixing parts 32a, 32c, 32e of the upper member 32 allow an intimate assembly, that is to say say surface against surface, bodies 31, 32 of the main frame 3, which improves the aesthetic appearance. In addition, such a main frame 3 facilitates the assembly of a pair of glasses by allowing to enclose the glasses between the lower member 31 and the upper member 32 as will be presented later. The housing portions 31b, 31d of the lower member 31 are curved to allow the reception of a glass whose periphery is curved. Preferably, each housing portion 31b, 31d of the lower member 31 is configured to respectively form more than 50% of the periphery of the housings 7G, 7D. Each housing portion 31b, 31d of the lower member 31 and each housing portion 32b, 32d of the upper member 32 are grooved so as to stably accommodate a glass in the thickness of the main frame 3. It It is no longer necessary to heat the frame or force-fit the lenses as in the prior art, which reduces the risk of chipping of the lenses. In this preferred embodiment, again with reference to FIG. 1, each fixing portion 31a, 31c, 31e of the lower member 31 comprises at least one first locking magnet 41. Similarly, each fixing portion 32a, 32c, 32e of the upper member 32 comprises at least one second locking magnet 42 adapted to magnetically cooperate with a first locking magnet 41. Two magnets 41, 42 are adapted to cooperate magnetically when they are attracted magnetically to one the other. The use of locking magnets 41, 42 makes it possible to securely connect the members 31, 32 of the main frame 3 in order to avoid any accidental disassembly and therefore a release of the glasses when the pair of spectacles is used by the end customer. In practice, if the upper member 32 of the main frame 3 is held fixed and a mass of one kilogram is suspended from the lower member 31, the members 31, 32 do not separate. The use of locking magnets 41, 42 nevertheless allows an optician or a user to replace the glasses in a practical manner without risk of damage. In addition, the optician / user may replace a lower member 31 by another lower member 31 of the lower body collection 3. Similarly, the optician may replace an upper member 32 with another upper member 32 of the collection of upper organs 32. The eyeglass frame 1 can thus be simply personalized. In this example, the left and right 31a securing portions 31a of the lower member 31 each comprise a single first locking magnet 41. Similarly, the left and right 32a and 32e attachment portions of the upper member 32 each comprise a unique second locking magnet 42. Thus, the edges of the main frame 3 are thin, which improves the aesthetic appearance. In this example, the central fixing portion 31c of the lower member 31 comprises two first locking magnets 41. Similarly, the central fixing portion 32c comprises two second locking magnets 42. The magnetic connection is reinforced at the bridge of the main frame 3 since this part is more massive than the side edges.

Alternatively, each fixing portion 31a, 31c, 31e of the lower member 31 comprises two first locking magnets 41 and each fixing portion 32a, 32c, 32e of the upper member 32 comprises two second locking magnets 42 so that ensure optimal maintenance of the main framework 3.

Preferably, each first locking magnet 41 of the attachment portions 31a, 31c, 31e of the lower member 31 is mounted in the bottom of a vertical cavity 51 formed in the thickness of the lower member 31 as illustrated in FIG. FIG. 2. Complementarily, each second locking magnet 42 of the attachment portions 32a, 32c, 32e of the upper member 32 is mounted in a vertical cavity (not shown) formed in the thickness of the upper member 32 In this example, each second locking magnet 42 protrudes from its vertical cavity so as to fit into the vertical cavity 51 in which the first locking magnet 41 is mounted.

Thus, during the assembly of the lower member 31 with the upper member 32 to form the main frame 3, the connection is, on the one hand, mechanical due to the insertion of the second magnet 42 in the vertical cavity 51 and, on the other hand, magnetic due to the magnetic attraction between the magnets 41, 42.

For example, the depth of a mounting cavity is 2 mm both for the lower member 31 than for the upper member 32, the diameter of a mounting cavity being of the order of 3- 5 mm. The vertical dimension of a first magnet 41 is of the order of 1 mm while the vertical dimension of a second magnet 42 is 3 mm so that the total length of the magnets corresponds to the total length of the two cavities mounting (3 mm + 1 mm = 2 mm + 2 mm). The connection is thus of the tenon / mortise type to ensure a mechanical attachment, the magnets 41, 42 ensuring the magnetic connection. Preferably, the magnets 41, 42 are connected to the members 31, 32 by gluing. It goes without saying that the placement of the magnets 41, 42 on the members 31, 32 could be reversed.

According to a first aspect, each lateral branch 2D, 2G is not articulated but orthogonally connected to the main frame 3 as illustrated in FIG. 1. Preferably, with reference to FIG. 3, each branch 2D, 2G comprises a mounting end 20 having at least one third locking magnet 43 adapted to cooperate with at least one fourth locking magnet 44 mounted at the rear of the main frame 3. Preferably, the attachment portions 32a, 32e of the upper member 32 each comprise a fourth magnet 44 extending orthogonally along the Z axis to the main frame 3. Each mounting end 20 of a 2D side branch 2G has a longitudinal cavity 21 extending along the axis Z along the length of the branch lateral and opening into a vertical cavity 22 in which is mounted the third magnet 43 as shown in Figure 3. To mount a 2D side branch, 2G, just introduce the quat rième magnet 44 in the longitudinal cavity 21 until it abuts with the third magnet 43 mounted in the vertical cavity 22. Thus, similarly to the assembly of the main frame 3, the lateral branches 2D, 2G are mechanically and magnetically connected to provide optimal support to the main frame 3.

According to a second aspect, each lateral branch 2D, 2G is articulated to the main frame 3 along a vertical axis of articulation extending along the axis Y. With reference to FIG. 4, each branch comprises a mounting end 20 comprising at least one third locking magnet 43 adapted to cooperate with at least one fourth locking magnet 44 mounted with a strap of the main frame 3. The mounting end 20 has a first cutout 23, preferably L-shaped, adapted to cooperate by complementarity of forms with a second cutout 24, preferably L, of the main frame 3 as shown in Figure 4. The third locking magnet 43 extends vertically from the first cut 23 of the side branch 2G / 2D to be received in a vertical cavity 52 formed in the second cutout 24 of the main frame 3. Similar to the assembly of the main frame 3, the fourth locking magnet e 44 is mounted in the bottom of the vertical cavity 52 to magnetically cooperate with the third locking magnet 43. Thanks to the shape of the cutouts 23, 24, the lateral branch 2D, 2G can turn around the third magnet 43 mounted in the vertical cavity 52 to form a hinge axis extending along the vertical axis Y. Thus, advantageously, the lateral branches 2D, 2G can be folded or unfolded relative to the main frame 43. Advantageously, always with reference to FIG. 4, the mount 1 comprises means for blocking a 2D lateral branch, 2G with respect to the main frame 3 in the unfolded position (orthogonal lateral branch 2D, 2G in the main frame 3) and in the folded position (branch lateral parallel 2D, 2G to the main frame 3) to ensure optimal magnetic hold. Indeed, if the lateral branches 2D, 2G were free to move, the magnetic link would be weakened. For example, the locking means comprise, firstly, a first locking ball 61 secured to a front wall of the 2D side arm, 2G and a second locking ball 62 secured to an inner wall of the lateral branch 2D, 2G and, on the other hand, a spherical cavity 60 formed in the rear vertical face of the second cutout 24 of the main frame 3. The locking balls 61, 62 are identical and adapted to cooperate by complementarity of shapes with the spherical cavity 60 of the main frame 3. When the lateral branch 2D, 2G is unfolded, the first locking ball 61 is locked in the spherical cavity 60 of the main frame 3. Similarly, when the lateral branch 2D, 2G is folded, the second locking ball 62 is locked in the spherical cavity 60 of the main frame 3. A spherical shape is advantageous because it allows to block / unblock the position of a side branch 2D, 2G in a suitable manner. ogressive, which limits any risk of wear. An example of implementation of a method of assembling a pair of spectacles according to the invention will now be presented. To assemble a pair of glasses, the optician first performs a step of selecting a lower member 31 in the lower organ collection 31 and a step of selecting an upper member 32 in the organ collection 32. Then, the optician performs a step of assembling the lower member 31 with the upper member 32 so as to maintain, on the one hand, the left lens between the left housing portion 31b, 32b and, on the other hand, the right lens between the right housing part 31d, 32d. During assembly, each glass is previously positioned in the grooved housing portions 31b, 31d of the lower member 31 since they form more than 50% of the periphery of the housings 7G, 7D, the glasses being then stable during assembly. During assembly, the second magnets 42 of the upper member 32, which project vertically downwards, penetrate into the vertical cavities 51 formed in the fixing portions 31a, 31c, 31e of the lower member 31 in the assembled position, the second magnets 42 of the upper member 32 are in abutment against the first magnets 41 disposed at the bottom of the vertical cavities 51, the magnetic attraction between the first magnets 41 and the second magnets 42 securing the assembly of the main frame 3. The lower 31 and upper 32 members are in contact by complementary shapes. Then, the optician performs a step of selecting a left lateral branch 2G and a right lateral branch 2D in a collection of lateral branches and assembles them on the main frame 3, in particular on the upper member 32 as illustrated in FIG. 1. During assembly, the fourth magnets 44 of the main frame 3 are introduced into the longitudinal cavities 21 of the 2D, 2G branches in order to cooperate magnetically with the third magnets 43. The frame 1 is thus fully customizable, which is advantageous.

The pair of glasses obtained is personalized to the tastes of the user and assembled quickly and conveniently, which reduces its cost. Such a pair of glasses is thus particularly advantageous.
