Description

[0001] SPECTACLE FRAME WITH HINGED, REMOVABLE ARMS [0002]

The present invention relates to an eyeglass frame with detachable legs connected by hinges, comprising a connecting element consisting of a bearing element and a pivot element, two detachable elements for each leg, the two elements of the eyeglass frame, That is to say to one of the front and legs, the components of the connecting part are connected to one of the members of the frame.

An eyeglass frame with hinged legs is generally provided with detachable legs whose rotation is made by screws. The legs are hinged and detachable legs, but they can not actually be detached, but the threaded release of the pin or its locking is separated by a specialist with tools (small jaws, threaded trowel) adapted to very small screws . Therefore, these frames can not be separated by the user except for exceptional circumstances.

If the screw is missing, it is necessary to attach the eyeglass leg to the frame again after the screw that has formed the pin is lost after advising the specialist that the pin is forcibly moved from the screw and can be released by the effect of opening or closing movement of the eyeglass leg .

In short, when the rotary part is moved in such a frame, that is, the leg is detachable only after the screw forming the pin is released.

In addition, there is an eyeglass frame with detachable legs, the threaded connector is integral with the head of the eyeglass face, and a snap-on fastening means is provided on the secondary connector to attach the eyeglass leg. The eyeglass legs are interchangeable with respect to the connection. The connection is a threaded connection with all its disadvantages. Moreover, the fixation of the eyeglass legs to the hinges requires a relatively complicated form-fitting connection as well as a hinge. This form-fit connection means changes the size of the leg end of the glasses and also affects the appearance of the glasses.

These glasses with detachable legs therefore have two side drawbacks and, if they have a screw-type hinge, there is no means of keeping the leg in either of its end positions (extended position, folded position) It is complicated as an additional fixing means to the leg, and also affects the leg appearance.

It is an object of the present invention to develop a spectacle frame, the legs of which are connected by a hinge without a screw, which can be detached and removed in a simple manner by a non-specialist, enabling the legs to be changed and the legs being suitable for cosmetic or functional requirements .

For this purpose, the invention relates to an eyeglass frame with legs connected by detachable hinges of the type defined above, said frame comprising a connection consisting of a bearing element and a pivot element, said connection comprising Features:

A. The bearing element,

- one side forming a main support surface,

- an adjacent side forming an auxiliary support surface, each of said surfaces being defined parallel to the connection axis to define an expanded position of said leg (2) and a folded position thereof,

The bearing seat being connected to the opposite side of the main support surface by a channel and the channel forming an opening in the side to form a passage for inserting the pivot into the bearing seat, Wherein the channel has an L-shaped profile, one end of the channel is open to the surface of the side, and the other end terminated by the bearing seat is directed to the auxiliary support surface,

B. The pivot element comprises:

The cap having a cap connected to the other part of the frame by its base and bearing the pivot by its side,

A) the cap is provided with a spring, the spring having two legs, one of which is connected to the base of the cap, and the other leg is capable of moving closer to the base in a resilient manner Thereby forming a guide and a support plate into the gap between the pivot and the base, the plate being configured to rest against the main support surface or against the auxiliary support surface depending on the pivot position of the leg.

Since the hinge of the eyeglass frame according to the invention consists of a bearing element and a pivot element and does not include screws, its manufacture is particularly simple and variable, which is advantageous when assembling in a factory, So that the legs can be configured to match the physical characteristics of the user. By eliminating the screws at the hinge, all the disadvantages of losing the screws can be avoided and the inconvenience of disassembling the hinge is eliminated.

When the eyeglass leg is provided as a bearing element or a pivot element, the hinge portion size is reduced and the hinge portion is separated into metastable position passages so that the hinge portion has a return motion to the expanded or folded position of the leg. Moreover, the spring that maintains the simplicity and assembly of the hinge thus produced also reproduces the over-opening function.

The eyeglass frame according to the present invention provides many other advantages and allows the legs to be easily separated by removing the screws, which in turn makes it easier and quicker to change the glasses. This is the operation performed by the optician when selecting the frame (front and leg). This also allows the user to freely set one or more of the functional equipment such as other structures, colors, materials or audio devices, mobile telephone receivers, "audio headsets" Ornaments or functional elements according to the present invention. This also allows the user to have other frames, such as different optics, sunglasses, sport glasses, and the like, at his disposal and fix the set of legs to these different frames, and the hinges of the other frames or legs .

The functional leg may be a leg having a very special shape, for example when performing sports, the glasses may be firmly fixed by passing around the ears with a thin or bulky leg when wearing the helmet.

Finally, and particularly importantly, since the frame according to the present invention does not include screws but includes a pivot which is integrated with one of the members of the frame, the connection can be separated very easily by non-experts, The expert does not need to intervene to replace the lost connection screw.

A particularly interesting feature is that the spring with the two-legs is a hairpin spring, one of which is connected to the base of the cap and the other is able to move closer to the base in a resilient manner, Thereby forming a guide and a support plate which enter into the space between the bases.

The embodiment thus formed is particularly compact and has a strong spring effect and has the effect of holding the leg firmly in the extended position and in the collapsed position and the contact surface between the guiding and support plate and the main or auxiliary bearing surface of the bearing element is relatively small Do.

According to an advantageous feature of the invention, the bearing element is supported by a tenon of the face of the frame and the pivot element is supported by the legs.

In another variation, the eyeglass leg has said bearing element and the frame has said pivot element.

This second embodiment is of interest when the pivot element is more complex than the bearing element in an assembly formed of one or more frames and a set of eye legs, since the number of sets of eye legs is greater, so that a frame with the most complicated elements to produce It is also desirable to provide more number of eyewear legs with bearing elements that provide a simpler element.

Finally, it should be emphasized that the bearing element is a hard component that constitutes the channel leading to the bearing seat. Thus, the position of the pivot in the bearing seat is a free position without clamping, thereby allowing the pivot to rotate freely in the seat.

According to another variant (not shown), the pivot element has a completely circular or non-polygonal cross section and the bearing seat is resiliently deformable to define the end point of the movement positions.

As another advantageous feature, the bearing element is a parallelepipedal block, which is formed in a plane perpendicular to the connecting axis zz, in particular in a rectangular cross-section and in particular incorporating a lug, Which are connected by edges forming a metastable position of the leg when passing from one position to another (the extended position (D) or the folded position (R)), forming a main and auxiliary support surface . This embodiment is particularly notable for its compactness.

In another advantageous feature, the pivot element is cut from a steel sheet comprising a base of the cap, the cut side thereof being folded at right angles and provided with holes for receiving the pivot, respectively, the spring being cut from the continuous part of the base While the second legs constitute a guide and a support plate.

This embodiment corresponds to the simple shape obtained by cutting, in particular laser cutting and folding or bending, and the force between the spring itself and the cap is directly transferred to the same material, and another element is produced in one piece. It also insulates any welds between the springs and the cap. Furthermore, according to the present embodiment, the base of the cap includes a continuous portion which is fixed to the leg or forms a bar (engaged) in the cavity of the leg.

This embodiment has the advantage of making the essential components of the hinge even and making the shape, structure and function of the legs deform without the specific fit of the hinge.

Another beneficial feature is that the inlet of the channel leading to the bearing seat is enlarged to widen from the side close to the auxiliary support surface.

This type of inlet facilitates moving the pivot into the channel to move it to the bearing seat.

Finally, the invention relates to an eyeglass system formed from one frame or more of interchangeable removable eyewear legs, as defined above, wherein the structure, shape, decoration and function of the system are arranged according to a pair of legs Each leg can be configured differently.

In order to facilitate the description of the present invention, the various figures are oriented in the direction of the symmetrical mid-plane or plane of the frame corresponding to the direction (oy) and the front face is oriented in the direction ox substantially in the cross- do.

The drawing is a plan view or cut through a plane perpendicular to the connecting axis of the leg shown, wherein the axis itself is shown perpendicular to all of the drawing planes.

Referring to Figure 1, the invention relates to an eyeglass frame 1 with associated legs, with half of the half being shown for a symmetrical (oy) axis. The front face 11 of the frame is substantially perpendicular to this axis or parallel to the axis ox. This axis system allows the orientation of the movable parts of the eyeglasses to be determined.

The description of the frame 1 provided with the aid of the drawings relates to a single leg 2 and its connection or hinge 3 which will be applied corresponding to the connection of the other legs of the glasses.

The eyeglass leg according to the invention is connected in a detachable manner by means of a joint constituted by two elements, a bearing element and a hinge consisting of a pivot element, the two elements being arranged in two parts of the eyeglasses, It is connected to either the front face or one of the two legs. In the embodiment provided below, the bearing element is supported on its front side, for example by a ledge on the front side, and the pivot element is supported by a leg coupled with this connection.

The eyeglasses comprise a frame 1 whose front face 11 has a lens (not shown), each side terminated by a ledge 12 which is supported by a bearing element 4 supported by a lug 13, And is connected to the legs 2 in a connecting manner, only a part of which is shown. The hinge (3) is completed by a pivot having a pivot element (5) integrated with the leg (2).

The legs 2 are parallel or substantially parallel to the axis oy in the expanded position 2 (D) and substantially perpendicular to this axis at the folded position 2 (R). The connected legs 2 are detachable due to the hinges 3, which will be described in more detail below.

To facilitate understanding of FIG. 1, the pivot element 5 is simply shown in its position without its cap relative to the pivot 52.

The legs 2 are provided in the region of the pivot element 5 with a leaf spring 53 formed by a hairpin spring and the hairpin spring is placed on the faces of the bearing element 4 so that the expanded or folded position of the leg 2 Stabilize.

The structure of the detachable connection or hinge 3 of the leg 2 will be described in detail with the aid of FIGS. 2 to 5, which schematically show the parts of the glasses in the hinge region, And is perpendicular to the connection axis zz which by definition passes through the housing 45 of the pivot 52 and the pivot 52 in the bearing element 4.

2, the bearing element 4 supported by the lug 13 at the end of the ledge 12 on the shaft 41 is a substantially parallelepiped block or at least a major supporting surface 42 and other adjoining side surfaces constituting the auxiliary support surface 44. The two planar surfaces 42 and 44 which are preferably planar are parallel to the hinge 3 axis zz and extend in the direction of the passage between the expanded position D and the folded position R of the eyeglass leg 2 associated with this bearing element 4. [ At the edge 43 which constitutes the metastable point of the staple.

The bearing element 4 has a bearing seat which is connected to the side 48 of the bearing element on the side opposite to the side constituting the main bearing surface 42 and has a channel (46). The inlet 47 is enlarged to facilitate the location of the pivot 52 and introduction into the channel 46. The channel 46, whose cross section is slightly larger than the diameter of the pivot 52, generally has an L-shaped outline, of which the larger segment is open to the third side 48 of the bearing element 4, Facing the surface 44.

The axial distances of the bearing seats 45 relative to the two support surfaces 42, 44 are essentially, but not necessarily, the same. The axis zz of the bearing seat 45 perpendicular to the plane of the drawing is also indicated by a point Ao corresponding to the axis of rotation of the bearing seat at this position. The bearing seat 45 is in fact the cylinder face of a semicircular section of the pivot 52 guide and its section is shown as a circle hunting across the semicircle. This contact is sufficient because the legs 2 and their pivots 52 rotate only during the stretching or folding motion of the legs 2 without continuously rotating.

Fig. 3 is a view cut in Fig. 1 and showing the structure of the pivot element 5 which is followed by the ends of the glasses legs 2. Fig. The element 5 is composed of a cap portion 51 whose two sides 511 meet the base 512 and according to the cut-away view perpendicular to the plane of Figure 3, the assembly has a U-shape. The cap part 511 is integrally associated with a pivot 52 which, for example, is framed or welded to engage the hole 513 in the two plates or sides 511. The two sides 511 are substantially triangular in shape and the base 512 constitutes a common side whereby the cap 51 is fixed to the eyeglass leg 2 and, for example, the cap and eyeglass legs are welded The legs are made of plastic material, for example, molded in itself, with suitable legs fixed thereto, including steel inserts. The fixture is similarly riveted (not shown).

The cap 51 carries a hairpin spring 53 whose first leg 531 is fixed to or forms part of the base 512 of the cap and the first leg 531 is, Respectively. The second leg 533 of the spring 53 passes through the gap between the pivot 52 and the base 512 of the cap.

3 shows the position of the second leg 533 formed by the solid line, and the position deformed by the stress is broken line and operated by the elasticity of the spring loop 532.

And the second leg 533 constitutes a guide and a support plate which meet with the loop 532 of the spring 53.

When the pivot element 5 is produced as a single part that is cut away from the metal surface and is folded into a single part, the second leg 533 of the spring 53 is pivotally mounted on two previously elevated sides 511, and then the pivot 52 will be connected to the sides 511 and secured thereto. Thus, the second leg 533 will be held in the space between the base 512 and the pivot 52.

3 illustrates the reference distance L between the axis Ao of the pivot 52 and the point B of the leg 2 in order to illustrate the function of the detachable connection. Point B is the base point perpendicular to the leg 2 (or relative to the base 512 of the cap 51) while passing through the axis Ao of the pivot.

Figure 3 also shows the distance dr corresponding to the guide and support plate spacing for the base 51 of the cap 51 and the distance dc corresponding to a constant compression of the spring 53.

The spring 53 is compressed more strongly by the loop 532 and actually pushes against the guide and support plate 553 relative to the base 512. [

The opening of the hairpin spring 53 to which the end of the leg 2 is attached meets the leg front end and the loop 532 lies on the back side.

1, the pivot 52 is positioned and held in this position by the bearing element 45. As the eyeglass leg 2 moves, the connection edges 43 The spring 53 pressing the main support surface 42 or the auxiliary support surface 44 is retained resiliently. With the orientation of the two bearing surfaces 42 and 44 and the orientation of the channels 46 that draw into the bearing seats 45, the pivot 52 is configured such that the attraction forces acting on the guide and support plate against one of the two bearing surfaces 42, As shown in Fig.

The L-shaped configuration of the channel 46 terminating in the bearing seat 45 opens the pivot 52 to the bearing element 4 side 48 opposite the side corresponding to the main support surface 42 Is pulled against the bottom of the sheet (45). The same applies to the case where the leg 2 is folded, wherein the rotation 52 is held on the bottom in the form of a cylinder with a half-angled circular cross section and constitutes the bearing surface of the pivot 52 in the bearing seat 45.

For each of the two illustrated positions, point B is shown as the reference distance L on the leg 2, point B in the folded position R has reference R _B and point D in the expanded position D, (D) maintains reference (R _D ).

The rotating movement is shown in arc form.

The fit or movement of the legs 2 in the bearing element 4 is explained below with the aid of Fig.

The legs 2 are positioned in an "open position " so that the legs 2 are folded against the connection to mount the pivot 52 of the legs 2 in the seat 45 of the bearing element 4. The legs maintain reference (2E) (fitting position). This orientation corresponds to a direction perpendicular or substantially perpendicular to the mid plane (oy) of the frame. To this end, the guide and support plate formed by the second leg 533 is connected to the auxiliary bearing surface 44 of the bearing element 4 so as to position the pivot 52 at the inlet 47 of the channel 46 Which assumes that the distance L between the rotation (point Ao) and the axis (zz) of point B is a fixed distance.

The legs 2 then slip from left to right (arrow F1) to advance the pivot 52 in the channel 46 until rotation reaches the small leg end sheet 45 of the L-shaped channel 46. This position at the assembly position is also shown in Fig.

As the pivot 52 advances in the channel 46, in this embodiment the channel spring causes the leg springs to gradually loosen and then abruptly turn to the final position at the channel small segment inlet.

In the final position, however, the spring 53 is firmly pressed against the auxiliary support surface 44 of the bearing element 4 to hold the pivot 52 in the bearing seat 45.

When the channel entry segment is perpendicular to the side 48, the spring 53 is retained in compression during passage from the large segment and when the pivot 52 reaches a small segment (position A2) in the channel 46 of the seat 45 It relaxes.

According to another variant of the channel 46 and inlet 47, a ramp 47a (Fig. 2) connects the side 48 with the channel 46, The compression of the spring 53 is facilitated.

The process is reversed to separate the legs 2 and begins at a leg position characterized by a reference point position B such that the legs 2 are at least substantially perpendicular (or alternatively, The spring 53 is pressed into the guide and support plate to guide the pivot 52 from the two-segment junction of the L-shaped channel 46 to position A2. From there, it is possible to pull the leg 2 to the left (arrow F2) and move the pivot 52 from the channel 46 to the position B. The eyeglass legs 2 are thus released from the bearing element 4.

The legs 2 are then replaced by other legs having different appearances or functions.

Figure 5a shows the folded position of the leg. This figure shows that the pivot 52 is pulled in the direction of the auxiliary support surface 44 by the guide plate.

The same applies to the position shown in FIG. 5B when the guide plate is pressed against the main support surface 42 or alternatively passes the edge 43.

Figure 5b shows the expanded position of the legs. This figure also quite schematically point (B _So) to the schematic stylized leg (2) (2So) shows an overheating open position. This overtemperature open position depends on the reference distance and the autonomous spacing between the legs and the main support surface 42.

In fact, this over-opening position is the end of the elastic movement position and is related to the possible elastic deformation of the leg 2, in particular the deformation of the spring 53.

FIG. 6 shows the disassembly / connection of the rotary part in the bearing element and the other positions of the legs with respect to the connecting part in sections 6a, 6b, 6c. In these three figures the reference axes (oy, ox) are marked to facilitate face, leg and orientation positions.

In this figure the bearing element 4 'meets the lug 13 of the previous embodiment.

According to Fig. 6a, the legs are unfolded and are positioned somewhat in succession of the legs 12.

Figure 6b shows the folded position of the legs 2 and holds the same orientation as in Figure 6a with respect to the frame front.

Disassembly of the legs 2 relative to the bearing element 4 is shown in Fig. 6c. The legs 2 or at least the pivot 52 are moved in the bearing seat 45 of the bearing element by the compression of the second leg 533 against the auxiliary support surface 44 and the pivot 52 is inserted into the inlet 47 ), Which is a very small length in this embodiment.

This position is also the engagement position of the pivot 52 of the leg in the bearing element 4. [

Figure 7 shows another position of the pivot element 5 relative to the bearing element 4 and still retains the axis ox, oy as orientation reference.

Figure 7a shows the position of the pivot element 5 at the entrance 47 of the channel 46 of the bearing seat 45 in the bearing element 4. The second leg 533 of the spring 53 is shown compressed.

Figure 7b shows the fit of the pivot in the channel and the engagement in the bearing seat. This fitting engagement corresponds to a snap-fit.

7C shows the final engagement position of the pivot 52 in the bearing seat 45. Fig.

7D shows the passage of the second leg 533 on the edge 43 corresponding to the metastable position separating the expanded position of the leg from the folded position.

Finally, FIG. 7e shows the leg positions when exaggeratedly open and reflected with a slight elastic deformation of the guide and support plate ends relative to the main support surface 42. FIG.

The above-described spectacle frame and its connecting portion are very simple to produce and have an advantage in that they are constituted by a small number of elements. Due to the position of rotation in the bearing element 4, the eyeglass legs 2 are easily replaceable. This facilitates the fitting of eyeglass frames for the user, and it also makes it possible to construct eyeglass frames consisting of a front and a set of interchangeable leg sets or pairs of eyeglasses with different shapes, colors, materials and, where appropriate, different functions Do. This allows the appearance of the eyeglass frame to be adapted to other situations, clothing, fashion items, or functional needs in a very wide range and allows the legs to adapt to the color or activity of, for example, clothes or bags.

It is also possible to consider a pair of eyeglasses legs as a seasonal article or a fashion article adapted to the front of the frame because it is very simple to fix or remove the eyeglass legs on the front of the frame and does not require specific tools.

Finally, since the pivot is integrated with the cap, there is no risk of losing the pivot as in the case of a pivot configured by a screw.

Figure 8 shows a modified embodiment of the frame at 8a and 8b. In this variant, the pivot element 5 is cut and composed of a folded and bent metal surface to form a flat bar 54 onto which is fitted a spectacles leg 2 'with a cavity 21 of a suitable shape. The eyeglass leg 2 'is integrated with the flat bar 54, for example by thermal deformation of the eyeglass leg 2' when made of a plastic material, or by bonding, bar or clipping, As shown in FIG.

8A, the pivoting element 5 'is cut from a regular rectangular sheet and its front end forms two sides 511 of the cap 51 when folded at right angles to the base. The spring 53 is cut from the plate forming the flat bar 54 and the cut tab is then folded and bent to form the hairpin spring 53. [ The second leg 533 constituting the guide and support plate of the spring is squeezed to enter the gap between the base 512 of the cap 51 and the pivot 52 housing. It is then located on the two sides 511 of the cap 51 and is there mechanically or fixed by welding or bonding.

The leg 2 'comprises a pivoting element 5', a flat bar 54, a spring 53, and, optionally, a cavity 21 for receiving the cap 51, I have.

The cavity 21 of the leg 2 'is provided with a catch (not shown) or a ramp on its inner side so that a window corresponding to the cutting out of the plate forming the spring 53 541 by pressing the remaining cross-member 542 at the end of the bar that is in contact with the bar 54.

In this embodiment, the pivoting element 5 'constitutes a standard element within the scope of the frame system according to the invention and accommodates other forms of the eyeglass leg 2' by sliding or fixing as indicated.

According to a variant embodiment, the spring of the pivoting element (not shown) is a hairpin spring oriented in a direction opposite to the orientations of the preceding embodiment.

According to another variant (not shown), the spring of the pivot element is a deformed leaf spring, one end of which is fixed or capped and the other end forms a guide and a support plate corresponding to the aforementioned guide and support plate do.

Finally, in a general manner, the invention also applies to the inverse kinematics of the above-mentioned embodiment, which consists in moving the parts of the frame with the bearing element and the pivot element, the frame having the pivot element and the eyeglass leg having bearing elements .
