[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment structure of a support leg for a nose pad of a spectacle frame, which is a type of frame in which a lens is directly connected by a connecting member without using a rim. .

[0002]

[Prior art]

 A nose pad for supporting the front frame portion is attached to the spectacle frame, and the nose pad is provided at the tip of the leg that curves from the front frame. A box is brazed to the tips of the legs, and a stopper protruding from the back of the nose pad is loosely fitted and fixed to the box. The stopper will be fixed around the screw provided on the box, but since the screw hole of the stopper is large, the direction of the nose pad can be changed within a certain range.

When the spectacle frame is made of metal and has a rim for holding the lens, the legs are generally brazed to the rim. Therefore, eyeglasses that do not use rims, that is, eyeglasses in which the left and right lenses are directly screwed by a connecting member, and the structure of which the screws are also screwed to the lens are becoming popular. Since this type of meganenet does not have a rim, the support leg of the nose pad is brazed to the connecting member.

However, if the connecting member is made of metal, the supporting legs can be brazed, but if the supporting legs are made of resin, brazing cannot be performed. Generally, it is said that if the support legs of the nose pad are made of resin rather than metal, they will be more elastic and deformable, the nose pad will feel better on the nose, it will be easier to wear glasses, and less fatigue will occur. It is being appreciated. Of course, it is possible to integrally mold the connecting member and the support leg with resin, but when selecting the connecting member to be surfaced according to the glasses, it is not compatible if integrally molded.

[0005]

[Problems to be solved by the present invention]

 As described above, the attachment structure of the nose pad support legs of the spectacle frame which does not form the rim has the above problems. The problems to be solved by the present invention are these problems, and provide a structure which is mainly made of resin and can be easily attached.

[0006]

[Means for Solving the Problems]

 The nose pad support legs of the spectacle frame according to the present invention are mainly made of resin as described above, and the spectacle frame does not have a rim, and the left and right lenses are screwed by a connecting member. It is fixed to the lens outer periphery with screws. The nose pad support leg of the present invention has a structure in which it is also used as a screw for fixing the above-mentioned lens, and has an attachment portion having a screw hole for that purpose. The leg extends from the attachment part in a curved shape, and the nose pad is fixed to the tip of the leg, but the structure for fixing the nose pad is arbitrary. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0007]

【Example】

 FIG. 1 is an embodiment showing the attachment structure of the nose pad support legs according to the present invention, and shows the back side of the eyeglass. In the figure, 1 is a lens, 2 is a connecting member, 3 is an armor, 4 is a temple, and 5 is a nose pad. It is clear from this figure that this kind of glasses does not have a rim for holding the lens 1, but the connecting member 2 located in the center connects and fixes the left and right lenses 1 and 1, and also 3 is also fixed to the lens 1.

A fastening piece is formed on the connecting member 2 and the end piece 3, and the fastening piece and the lens 1 are fixed by screws 6. The nose pad 5 is fixed to the front end of the support leg 7 so that its direction can be changed within a predetermined range. The support leg 7 is curved and extends from the attachment portion 8, and the attachment portion 8 is fixed by the screw 6.

FIG. 2 shows a detailed view of the state where the nose pad 5 is fixed to the tip of the support leg 7. A fitting portion is formed on the back side of the nose pad 5, and the ball at the tip of the support leg 7 is fitted and fixed to the fitting portion. Therefore, the direction of the nose pad 5 is set to the above ball. The structure is adjustable as the center. The support leg 7 projects from the attachment portion 8 and extends to form a large curved portion 9, and has a linear portion 10 continuous with the curved portion 9. The curved portion 9 facilitates flexural deformation of the support leg 7 and also has a function of preventing damage to the support leg 7. Further, the attachment portion 8 has a screw hole 11 through which the screw 6 is inserted, and a nut 12 is screwed into the screw 6 to fix the attachment portion 8, and at the same time, the lens 1 is tightened to fix the connecting member 2 of the connecting member 2. It is fixed to the fastening piece.

FIG. 3 is a sectional view showing a state in which the lens 1 and the fastening piece 13 of the connecting member 2 and the attachment portion 8 are fastened with screws 6. The material of the connecting member 2 is not limited, but if it is metallic, a washer 14 made of resin or the like is interposed so that the fastening piece 13 does not come into contact with the lens 1, and the attachment portion 8 and the lens 1 are joined together. A washer 14 is also used to fasten the screws.

Therefore, since the attaching portion 8 is made of resin, the washer 14 may not be used, and if the attaching piece 13 of the connecting member 2 is made of resin, it is The washer 14 interposed between the lens 1 and the lens 1 may be unnecessary. However, in that case, the shapes of the fastening piece 13 and the attachment portion 8 that can contact the entire surface of the lens 1 are desirable. As described above, the following effects can be obtained by using the attachment structure for the nose pad support legs according to the present invention as a screw.

[0012]

[Effect of device]

 According to the present invention, the nose pad support legs can be attached by using a fastening piece of the connecting member and a screw for fixing the lens, and the support legs can be manufactured as an independent part. In addition to being possible, the attachment means is simple and convenient. Therefore, the support leg may be made of resin or metal, and the attachment structure is simplified as compared with the conventional case where the support leg is formed by extending from the connecting member. On the other hand, by molding the support leg as an independent part, it becomes a diversified leg shape, and it is possible to use a support leg suitable for glasses.
