DETAILED DESCRIPTION OF THE INVENTION The present invention relates to eyeglass frames, and more particularly to eyeglass frames comprising a support structure and a removable facial assembly.

In general, this type of eyeglass frame facilitates the installation of ophthalmic glasses or lenses that are compatible with such frames, and the conditions of use of the eyeglasses (e.g., nearsightedness or farsightedness, ambient light conditions). etc.) to facilitate the replacement of glass according to the user's request. Furthermore, the practice of the present invention allows the various possible eyepiece assemblies to be accommodated in a space smaller than the dimensions required of a complete eyeglass frame.

French patent no.
No. 2,094,810 and US Pat. No. 3,713,732 could not be obtained using the conventional technology.

The eyeglass frame directed by the above-mentioned patent has a removable facial assembly with an intermediate bridge piece or saddle constituted by two parallel transverse pieces;
A support body with support studs.

From the standpoint of securing the facial assembly, the stud has two parallel grooves that engage one of the cross pieces of the facial assembly.

The above-mentioned conventional eyeglass frame satisfies all the above-mentioned requirements. However, since the facial assembly is assembled by engaging the grooved studs of the support, this structure poses a risk of inadvertent separation of the support and the facial assembly.

An object of the present invention is to provide an eyeglass frame that overcomes this drawback.

The present invention aims to provide a spectacle frame of the type described above, which allows the support structure and the facial assembly to be assembled without clearance and with a good appearance.

To this end, the spectacle frame of the present invention is made of a combination of two separable parts, one part being the support structure and the other part being the removable facial assembly. one of the parts has a locking member;
The other has a recess for the locking member. The locking member is arranged between a rest position in which the two parts can be separated and an operative position in which the locking member cooperates with the recess and locks the support and the face assembly together when they are assembled together. Moving.

A spring is provided to bias the locking member to its activated position. The locking member remains in that position unless voluntarily pushed against the spring force to the rest position. Accidental separation of the support and facial assembly is thus prevented.

Hereinafter, non-limiting embodiments of the present invention will be described with reference to the drawings.

The two elements of the eyeglass frame according to the present invention are
Shown separately in the figure. These elements each consist of a support structure 1 and a facial assembly 2. As is known, the support structure 1 has two side members or arms 3, 4 which are hinged to a central member 5. The body 2 has two hoops 6, which receive respective lenses. The hoops 6 are interconnected by bridge members or saddles 8 and carry a nose plate 9. The upper edge of the saddle 8 forms a central recess 11 formed by a notch 11', shown in detail in FIG.

As shown in FIG. 2, the notch 11' is open on one side of the saddle with a U-shaped profile 12 and with a partially circular profile 13 on the other side of the saddle. The diameter of the contour 13 is greater than the distance between the branches of the U-shaped contour. A shoulder 14 is thus formed between contours 12 and 13.

This shoulder 14 serves as a stop for a locking element 15 provided in the intermediate part of the support structure 1.

Its intermediate central portion 16 has a U-shaped cross section complementary to that of the saddle 8. Therefore, the saddle can be inserted by extending it between the flanges at the center. Its flange supports the locking member 15 in a position corresponding to the position of the notch 11' on the saddle 8.

FIG. 3 is a detailed view of member 15. This member forms a laterally movable head 15' of the central part 16 of the intermediate part of the support structure. The head 15' has one end 17 constituting a key accessible from outside the part 16. The lateral dimensions of both ends of the head 15' are larger than that of the notch 11' of the saddle 8. The set screw 18 cooperates with the right end of the head 15';
Limit the stroke length of that displacement. A spring 19 is provided within the central bore with the head between the bottom of the central bore and the flange of the central portion 16 of the support structure. The spring biases the head to the left as shown in FIG.

A slot 20 is formed in the lower edge of the central portion 16 of the support structure. The width of the slot is selected to allow insertion of the saddle 8 of the body 2.

4 to 6 illustrate each step of assembling the support structure to the main body according to the present invention.

For assembly of these parts, head 15' is pressed to the right by applying pressure on key 17 in the direction of arrow F in the figure (FIG. 4). The central portion 16 of the support structure is grasped by the operator's hand. head 1
The end of 5' is thus housed in the central portion 16 and separates the slot 20.

The operator inserts the saddle 8 in the direction of arrow F' while holding the main body 2 with his other hand. head 1
Since the end 21 of 5' is in the retracted position, there is no problem with this operation (FIG. 5).

The operator then releases pressure on the key 17, so that the spring 19 forces the head 15' to the left to the operating position of FIG. 6, in which the end 21 rests against the shoulder of the notch in the saddle 8 of the body. 14, the spectacle frame-to-face assembly and support structure of the present invention are fixedly connected to each other. The diameter of the end 21 of the head is selected to prevent the head from slipping out of the notch 11' of the saddle, whose width is less than the diameter.

The central part 16 of the support structure has a complementary contour to the saddle 8 of the body 2. This complementary profile feature ensures guidance and centering of the saddle on the support structure. The central portion 16 forms the interior groove of the saddle and completely encloses it with minimal clearance.

The head 15' is located within the central part. Therefore, the masking structure is advantageous in terms of the aesthetic appearance of the eyeglass frame.

When separating the face assembly from the support structure, for example, the main body can be stored or replaced with another eye assembly depending on different viewing conditions (nearsighted, farsighted, protective, etc.). Thus, the head 15' can be pressed by holding the central part of the support structure with one hand, and the saddle in the central part of the support structure can be removed with the other hand.

In another embodiment shown in FIG. 2a, a ramp 10' is provided adjacent each end 10 of the circular profile 13 of the notch 11. Due to these inclinations, the facial assembly 1
0 to the support structure 1 without having to pressurize the head 15'. The user simply pushes the saddle of the body into the central part 16. The head then engages the ramp 10' and temporarily pushes it to the right in FIG. The head enters the storage recess and the support structure is rigidly connected to the facial assembly. When removing the facial assembly, it is of course necessary to pressurize the head 15' forming the locking member 15.

In the embodiment described hereafter, the spectacle frame comprises two symmetrical connections provided on the frame.
Each of the connections has a locking member and a mounting hole near the connection point between the body and each of the two side pieces of the support.

Because of the two connections, the structure formed by the facial assembly and support structure is strengthened. Furthermore, the aesthetic appearance of the saddle connecting the glass of the body is improved by the absence of a connecting member.

FIG. 7 shows a second embodiment of the invention. This assembly has two glasses or lenses 31,
These are supported by a bow piece 32 which forms a saddle between these glasses. A nasal support plate 34 is provided in a known manner.

Each end of the bow piece 32 has an ear piece 35. The ear pieces are U
It has a letter-shaped notch 36. The surface of the lug has a circular recess, the depth of which is greater than the width of the notch 36, as shown in FIG. This applies similarly to the notch shown in FIG.

FIG. 8 shows a support structure connected to the body of FIG. This structure includes two hinge arms 38, a bow piece 39 complementary to the bow piece 32 of the facial assembly, and a bow piece 39.
and two connecting members 40 inserted between the arms 38
Consists of.

FIG. 8a is a partial view of one connecting piece 40.
A screw 41 pivotally attaches the arm 38. This connecting piece 4
0 opposite the end in which the hinged connection is formed is configured to receive a complementary locking member, such as a head 42. The head 42 has a hole for receiving a spring 43, which biases the head 42 in the direction opposite to arrow F. The locking screw 44 cooperates with the intermediate groove in the head to limit the stroke length of that head. This screw allows the spring 43 to be mounted in a position where a strong prestress is applied while preventing the head from coming off.

To attach the facial assembly to the support structure, the ear piece 35 is inserted into the associated head by utilizing the elasticity of the bow piece 32, which is slightly sloped at the saddle. At this time, the key 45 of the head 42 is pressed in the direction of arrow F. Figure 8a shows the position of the head 42 when the key is pressed. Ear piece 35 is an arrow
When inserted in the direction F' and releasing pressure on the head 42, the head portion 46 is inserted into the circular recess 3 of the ear piece.

This corresponds to that explained with respect to FIG.

The spectacle frame, in this second embodiment of the invention, consists of a coupling body attached to the two ends of a bow piece, which bow piece is connected on the one hand to a coupling member 40;
On the other hand, the ear pieces 35 are connected. Thus, the attachment of the facial assembly to the support structure is enhanced. The saddle, which is not associated with any connecting body, results in a simple and regular design, which is good in terms of the aesthetics of the glasses.

Figure 7a shows the ear piece 35 in the circle area in Figure 7.
This shows the deformation of In this variant, the notch 36 is in a vertical configuration. It is thus possible to mount the facial assembly on the support without stacking or folding in the area of the saddle. In this example,
The locking screw 44 naturally moves. This transformation is
As will be clear to those skilled in the art, no problems of implementation arise.

FIG. 10 shows the bow piece 32 and the ear piece 35 integral with the hoop 32, which are made of metal material and which hold the spectacle lens by means of a V-shaped groove 32''. By the way, the lug piece 35 joined to the bow piece 32 is shown.4
At 8, conventional means for hoopering the spectacle lens are provided and held by threads of plastic material such as nylon. The embodiment of FIG. 12 is similar to the previous embodiment, except that the ear piece 3
5 is integral with the bow piece 32. The ear piece of FIG. 13 is removably attached to the hoop 49 of the eyeglass frame. It is adapted to be secured by known clamping means (not shown) operated by screws 50.

FIG. 14 shows another embodiment of the eyeglasses of the present invention.
The facial assembly and support structure are preassembled. The ears 35 project perpendicularly from the plane of the main body. With this arrangement, unlike the embodiments of FIGS. 7 and 8, the ears 35 are engaged with the locking head without the aid of the elasticity of the spectacle frame.

FIG. 15 shows a sectional view taken along line 9--9 in FIG. 14. Assembly of the ears and head is performed as previously described with respect to FIG. 8a, except that the orientation of head 42 is different.

FIG. 16 shows the deformation of the lug in the embodiment of FIG. 14. This ear piece is constituted by a metal insert, the leg 35' of which is embedded in the plastic part constituting the bow piece 32 of the main body of the spectacle frame. In another variant of FIG. 17, the lug has two bevels 51 at its free end to facilitate insertion of the lug around the locking head. Such a bevel can be provided in any embodiment of the lug that is incorporated into the eyeglass frame of the invention. When attaching the facial assembly to the corresponding support structure, the bevel temporarily pushes the head back against the action of the spring 43, applying additional pressure on the keys of the head 42.

FIG. 18 is similar to FIG. 14, but shows yet another embodiment of the spectacle frame of the invention. The locking head 42 forms the hinged connection member of the associated arm and replaces the screw in the embodiment of FIGS. 8a and 15. For this purpose, the ear piece 35 is fixed on the bow piece 32 of the body in the horizontal position of FIG. Head 42 is attached to the corresponding end of arm 38 with its axis substantially perpendicular. The end of this side arm is substantially U-shaped and complementary to the lug 35 to accommodate the lug with minimal crissance.

The cross section of FIG. 19 shows the body on the arm of FIG. 18.

In this view, the head 42 is held on the arm 38 by a locking screw 44, with a groove on the head 42 below the first groove enclosing the head with the distal ear 35 of the screw. 52. Because of the locking screw 44, the spring 43 prestresses the head 42 and strengthens the assembly constituted by the ear and head.

When installing the eyeglass frame of the present invention, the ears of the body are inserted into the ends of the corresponding eyeglass frame while applying hand pressure on the head 42. This pressure is then released and the head lifts up to lock the ears onto the arms.

The arm and facial assemblies are thus securely locked together. A rounded portion 35'' at the free end on the ear piece 35 allows the arm 38 to be rotated about the axis of the head into the spectacle frame.

In an alternative embodiment, the ears 35 are chamfered as shown in FIG. 17, the purpose of which is as explained in that figure.

Bow piece 39 of the support structure (Fig. 8 or 14)
can be omitted, and the eyeglass frame is composed of a facial assembly and two removable arms, and the facial assembly can be replaced by one with different characteristics.

When using a structure in which the support structure is made up of two arms, on the one hand it is possible to use side pieces without rigid hinged joints, on the other hand it is possible to use various combinations of arms and associated face-to-face assemblies. It is possible to form If one arm is damaged or lost, the user can replace or repair it himself, and whatever specific conditions the selected facial assembly and arms can be conveniently combined. Glasses can also be adapted to

Additionally, the position of the head and associated ear pieces can be reversed on the facial assembly and support structure for aesthetic reasons.
Connectors 35, 36, 40, 42 may also serve to rigidly connect bow segment 32 of the facial assembly to a corresponding arm.

The present invention is not limited to the illustrated embodiments, but can be modified in various ways by those skilled in the art.
