Description

Spectacle frame with detachable legs {SPECTACLE FRAME WITH DETACHABLE ARMS}

The present invention relates to a spectacle frame with detachable legs, consisting of a face provided with tenons, each connected to a spectacle arm by a hinge, more particularly. Each tenon is closed (terminated) by two lugs bent inward and has a hinge pin, and each leg has lugs of the tenon at its end region facing the hinge. A frame of construction is finished by a base having two lugs positioned between and bent at right angles inward to be connected to the hinge pin.

Such spectacle frames generally exist in a number of forms.

An object of the present invention is to develop a spectacle frame of the type defined as described above, which attempts to adjust the spectacle frame in order to adapt the spectacle frame to the user's appearance, or more generally, to the shape of the spectacle leg desired by the user. It is possible to easily change the shape of the spectacles legs by making it easy to try out different alternatives at the point of view, or otherwise functionally and / or aesthetically according to certain requirements, for example according to some aesthetic needs. It is to provide such a type of spectacle frame that allows the appearance of the spectacle frame to be altered in order to properly adapt the legs.

In order to achieve the above object, the present invention,

Two lugs of each arm are terminated by two hooks forming a pin seat, wherein the two seats of the hooks are the base of the spectacle leg Is arranged to align and open in the inner direction of the, and has a cross section corresponding to the cross section of the pin of the tenon,

The base of the spectacle leg comprises a resilient tab which is separated from the base between the two lugs,

The two hooks receive the pin of the tenon and the elastic tab is configured to face the outside of the tenon to resiliently press the hooks against the pin.

Eyeglass legs provided with such a hinge portion are very easily worn or detached by a simple operation, making it possible to easily and quickly try different eyeglass legs of a wide variety of shapes and decorations when purchasing the eyeglass frame. It also makes it possible to freely use sets of glasses legs to be adaptively adjusted in terms of color or form depending on the clothes the user is wearing or his activity. For sports activities, it is possible for the user to change the shape to glasses legs that keep the glasses firm, whereas for everyday use the user will be able to use legs that are lighter or do not need to be securely fixed to the head. .

According to an advantageous feature of the invention, the end of the tenon has a wedge at which the tab of the spectacles leg rests against it, the wedge having a tab between the open and folded positions of the leg. Form a support position of a metastable relative to it.

Thanks to this shaped wedge, and in particular if the wedge is made of plastic material, the tab of the leg is supported smoothly and without wear, while at the same time benefiting from the metastable position, the folded or folded position of the glasses legs. It can be placed in either.

Particularly advantageously, the spectacle frame of the present invention makes it possible to over-opening and at the same time limit the excessive opening operation so that the hinge is not overly deformed or pressed. For that purpose, the outside of the tenon the tab is held with is provided with an over-opening stop that limits the forward movement of the spectacle leg tabs when it slides on the outside of the tenon during over-opening. .

According to another feature of the invention, the over-opening stop member is formed on the wedge.

The tenon pin may be integrally connected to the lugs, for example by welding, but the pin engages the holes of the lugs of the tenon having the same diameter as the hinge pin, which in itself translates into the holes. It consists of a cylindrical element having a circular cross section so that it can be slid by a translation and held therein, for example by welding.

According to a further advantage of the invention, the holes of the lugs of the tenon have the same diameter as the hinge pin, which is a cylindrical element of circular cross section so that it can be slid by translational movement into the holes and held therein.

According to the final embodiment, it will be possible for the pin to be easily replaced when worn. The wedge retains a dual function in the present assembly, ie the retaining and over-opening limiting function of the pin. Since the wedge thus has a stop member that limits over-opening, the wedge is automatically held in place on the tenon, and the wedge stops at the front of the tab that lies outside of the wedge when the spectacles legs are unfolded. You can move backward in the unlock (unlock) direction only until you are facing.

In general, although the present invention simplifies the manufacture of spectacle frames in areas such as tenons, pins, wedges and spectacles legs, such spectacle hinges offer numerous advantages in the removal, replacement, or exchange of the legs.

According to FIGS. 1 and 2, the present invention discloses a spectacle frame composed of spectacles face 10 provided with books 20 each supporting the spectacles leg 30 by a hinge 40 on the axis x-x. The hinge 40 allows the legs 30 to be unfolded or folded about the face 10 as shown in FIG. 2. The hinge 40 in the unfolded position also makes it possible to over-open as shown in FIG. 2.

Since the spectacle frame has a symmetrical structure with respect to the center surface MM, a detailed description of the present invention is based on the half of the spectacle frame, that is, one of the tenons 20 and its hinge 40 and the corresponding legs 30. Will only be limited to.

3a to 3c show in more detail the configuration of a typical embodiment of the hinge 40 according to the invention.

3A-3C are internal views A of the flattened eyeglasses leg 30 and tenon 20 corresponding to the side facing the wearer's head.

The tenon 20 is finished by two lugs 22 that are bent at right angles to the interior (A). The lugs 22 have hinge pins 41 which are received in the holes 220.

The pin 41 may be fixed to the lugs 22 by welding, or may be detached, and is also held in place by, for example, a flat portion formed in the pin and engaged on the edge of the tenon in the region of the hinge. It may be closed by a wedge that is present. This configuration will be described further below.

The spectacles leg 30 is shown only a base 31 or end disposed on the side of the hinge 40, which includes two lugs 32 that bend at right angles to form hooks 33. The hooks 33 are aligned (x1x1) and open toward the bottom in the inner direction of the base 31, ie according to the arrangement of figure 3a. The sheets of the hook 33 have a cross section corresponding to the cross section of the pin 41 of the tenon 20.

Between the lugs 32 with hooks 33, the base 31 of the spectacles leg 30 has an elastic tab 34, which is preferably the material of the spectacles leg or the spectacles leg 30 ( Metal) so that it is formed to be elastically deformed. As shown in FIG. 3A, lugs 32 with hooks 33 attempt to cross pin 41 of tenon 20, with elastic tab 34 tenon 20 (side B). Face to outside.

3A shows the spectacles leg 30 positioned to face the tenon 20.

FIG. 3B shows starting the placement of the hooks 30 over the pins 41 of the tenon 20 between the lugs 32 with the pins 41, wherein the tab 34 is a pin 41. Pressing is first applied against the outside (side B) of the tenon 20 by resiliently deforming to place the hooks 33 above or at least the hooks 33 pass over the pin 41. This movement can be made parallel or inclined to the pin 41, first passing one of the hooks 43 over the relevant portion of the pin 41, and then, by the action of the lever, the pin 41. In order to resiliently deform the tab 34 while staying by means of a first hook on it, the other lug 32 with the hook 33 is lifted so that it passes over the pin 41 and then thereafter. It elastically returns to reach the position shown in FIG. 3C.

When the hooks 33 of the lugs 32 are positioned on the pin 41 between the lugs 32 of the tenon, the elasticity of the tab 34 that is squeezed against the outside B of the tenon 20. The silver retains the hooks 33 against the pin 41 and causes the spectacles leg to rotate relative to the tenon. Normal pivoting motion of the leg will not separate the hooks 33 from the pin 41.

The hooks can only be separated by a violent upward movement of the end of the spectacles leg which sufficiently deforms the tab 34, but since this movement is not natural and easy to occur, there is no risk of accidental occurrence.

To remove the spectacles legs it is necessary to perform a twisting motion using the lever action and then perform a pivot effect using one of the hooks held on the pin as a support point for releasing the other hook. The hooks used are more easily separated.

In this embodiment (Figs. 3A, 3B, 3C), the elastic tab 34 is beyond the position of the axis x1x1 of the hooks 933. These figures show an example of the tenon 20 provided with the elements forming the wedge 40, which will be described further later. However, the cooperation between the pins 41 and the hooks 33 forming a bearing at the end of the leg 30 is in general sense that the tab 34 remains outside of the tenon 20, or else the end of the tenon. It is the same whether it is on the outside of the wedge 40 disposed in the same. The wedge 42 mounted at the end of the tenon 20 between the wall of the tenon 20 and the pin 41 at the interval between the lugs 22 is opened or opened with the folded position of the leg 30. Cooperate with elastic tab 34 to form a metastable position between the positions.

According to the embodiment to be described below, the pin 41 has the same diameter as the diameter of the holes 220 in the lugs 22 and is free to slide there for mounting or replacement thereof. It is held in place by a welding point between the lug 22 and the end (s) 411 of one or both of the pins 41 or the pins 41 are suitable for facing the interior of the tenon 20. It has a flat portion 412 that defines a passageway for receiving a wedge 42 of thickness. The flat portion 412 only occupies a predetermined length on the pin 41, which generally corresponds with the width of the wedge 42, whereby the wedge itself is prevented from being transformed by the cooperation of the shape. When engaged on the end 21 of the tenon 20, the pin 41 itself is prevented from translating in the longitudinal (vertical) direction (axis (xx)).

4A and 4B show the end 21 of the tenon 20 provided with a pin 41 having a flat portion 412.

According to FIG. 4A, the end 21 is provided with a rectangular notch 210 of arbitrary length. The notch is arranged, for example, in the middle between the two top and bottom edges of the tenon 20. The lugs 22 have hinge pins 41, which are shown as cuts to represent the notches 210.

FIG. 4B is a side view of the tenon 20 showing the flat portion of the pin 41 between its ends 411, for example in an intermediate position. The pin 41 is arranged about the axis xx such that the flat portion 412 is opposite the interior A of the end 21 of the tenon 20 so that the notch 210 faces the notch 210.

5 shows the shape of the wedge 42 that will be placed on the notch 210 and on the end 21 of the tenon 20 as its partial views 5a-5d. With the inner (A) / outer (B) direction direction defined above, according to FIG. 5A, the tenon 42 has an outer boundary delimiting two longitudinal grooves 423 on each side. It is a generally parallelepipedal element having an outer limb 422 and an inner limb 421. The front surface of the wedge 42 has a horizontal hole 424 leading by the grooves 423 and the inner branch 421 is configured such that the stop member 425 is placed on the front surface.

The longitudinal cross-sectional view of FIG. 5B shows the parallelepiped shape of the wedge 42, its opening 424 and the stop member 425 in more detail. 5C shows the two longitudinal grooves 423 and the stop member 425.

Finally, the top view of FIG. 5D shows the shape of the wedge portion and stop member connecting the inner fork 422 to the outer fork 421 bounded by two longitudinal grooves 423 and the front opening 424. The arrangement of 425 is shown.

5a to 5d show one of the wedges for engagement by form-fitting connection at the flat portion 412 closing the pin 41 in the direction (xx) and at the end of the tenon 20. An embodiment is shown. The wedge 42 is preferably an element made of a plastic material.

6A and 6B show the assembly of the wedge 42 on the end 21 of the tenon 20 to close the pin 41 by the flat portion 412 described above.

6A shows how the wedge 42 slides into the notch 210. The cross-sectional view of FIG. 6B shows the position of the wedge 42 engaged with the flat portion 412 by the inner fork 421, where the wedge 42 is with the notch 210 in the longitudinal grooves 423. It slides on the edges of the front end 21, outside of which a stop member 425 is visible.

The inner blade 421 of the wedge 42 has a thickness e corresponding to the distance between the bottom of the flat portion 412 and the interior of the end of the tenon 20.

7A and 7B schematically show the hinge 40.

7A shows the unfolded spectacles legs 30. In this position the elastic tab 34 of the spectacles leg 30 bears against the outside of the tenon 20, where a wedge 42 is provided.

The tab 34 is freed by the side cuts 341 to a sufficient length of the base 31 of the spectacles 30, thereby elastically deforming the remaining portion of the leg 30, which is the leg 30. This is even more so since the corresponding portion of) is strengthened by two lugs 32 which are bent and abutted at right angles.

The front edge 342 of the tab is disposed at any distance (a) from the stop member 425 which terminates the outer face of the wedge 42 in this position to constitute the over-opening limit. In fact, the over-opening movement with respect to the pin 41 causes the tab 34 to slide over the outer surface of the wedge 42 until its front edge 342 faces the stop member 425 of the wedge 42. Makes it possible.

The arrangement of the stop member 42 and the elastic tab 34 is selected to limit the over-opening to a predetermined angle.

The folded position of the leg 30 shown in FIG. 7B is in this position an elastic tab 34 is leaning against the front edge of the wedge 42, which constitutes a metastable position by its front edge 426. The eyeglasses leg 30 cannot thereby stay in the intermediate open position and is forced to move to either the folded position of FIG. 7B or the unfolded position of FIG. 7A due to the elasticity of the tab 34.

Wearing and detaching the spectacles leg 30 is performed as already described with reference to FIGS. 3A-3B. The principle of detachable operation here is achieved by lifting the two hooks 33 against the pin 41 by elastically deforming the tab 34 seated on the outside, wherein the spectacles leg 30 is in an open position. The operation is in progress.

The disassembly is preferably in two stages, first lifting one hook 33 and twisting it in length in front of the leg 30 to allow it to pass over the pin 41 via twisting and levering. After performing the Sting operation, the second hook 33 is easily removed because the first hook is released. Wear may be in the reverse order.

As long as the pin 41 is not integrally formed with the lugs 22 of the tenon 20, it may be changed, i.e., once the leg 30 associated with the pin 41 has been detached, the wedge 42 is opened. It may be exchanged by removing it.

This detach / reattach function of the eyeglass legs allows the user to adapt the front of the eyeglass frame to any particular leg or to change the shape, color, and appearance to the desired shape, for example, by making it easier to try several times at the point of purchase of the eyeglass frame. It makes it possible to adaptively replace eyeglass frames according to any aesthetic or fashion wishes or needs.

It will be appreciated that the technical features of the present invention relate only to a portion of the spectacles legs in the vicinity of the hinge 40 and thus provide considerable freedom in terms of aesthetic design for the entirety of the spectacles legs 30.
