Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mounting structure of a nose pad for supporting a front portion of an eyeglass frame against a nose.

[0002]

[Prior art]

 The spectacle frame is mounted on both sides of the front part so that the vine can be folded, and a nose pad is attached to the center of the front part. In other words, you can wear glasses by putting the nose pad on both sides of the nose to support the front part and hanging the vine on your ears.

By the way, this nose pad is generally made of a non-slip resin material so as to fit into the nose and is attached to the tip of a leg extending from the front part. Of course, the material of the nose pad is not limited to the above-mentioned resin, and a metal such as titanium may be used in some cases, and various attachment forms of the nose pad are known, as shown in FIG. Mounting structures are the most common form. The base plate (c) of the fastener (b) is embedded in the resin nose pad (a), and the fastener (b) protrudes from the front of the nose pad (a) and extends from the front. It is attached to the box (d) brazed to the tip of the leg. A through hole penetrates through the fastener (b) and fits into the box (d), and a screw (e) screwed into the box (d) is inserted into the through hole. Since the through-hole is relatively larger than the screw diameter, the nose pad (a) is given a lift (change in direction).

In order to mount the nose pad (a) with such a structure, a small box (d) is formed, a screw hole is drilled in the box (d), the tip of the leg extending from the front portion and the box (d) are attached. )), And furthermore, screwing work with the fastener (b) fitted in the box (d), etc., are numerous and complicated, resulting in high cost.

[0005]

[Problems to be solved by the present invention]

 As described above, there is a problem as described above in attaching the conventional nose pad. The problems to be solved by the present invention are these problems. The present invention provides a nose pad attaching structure which is simpler in construction, inexpensive in manufacturing and assembling, and can be replaced freely.

[0006]

[Means for Solving the Problems]

 In the nose pad attaching structure of the present invention, a claw is formed at the end of the leg extending from the front part without using a box as in the prior art, and the claw is engaged with the hole of the fastening tool protruding to the back side of the nose pad. Stopped. The shape of the claws is not particularly limited. "Agaki" is given.

[0007]

[Embodiment of the invention]

 The shape of the nose pad is not the object of the present invention, and the nose pad may be of any shape and may be made of any material. The fastener can be made of metal and embedded together with the molding of the nose pad as in the prior art, or the fastener can also be integrally formed of resin. The hole formed in the fastening device is generally a square hole because the nose pad does not rotate freely, and the claw that fits into the hole has a shape that fits with some backlash.

Generally, two claws are formed facing each other, the claws can be bent by elastic deformation, and both claws are bent when they are fitted into the holes. The tip of the claw has an inclined surface, and can be pressed against a hole, and at this time, the claw can be bent by elastic deformation. The claw is not limited to being made of metal, in particular, of a spring material, but it is also possible to use a shape memory alloy or a resin material rich in elastic deformation. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 shows a general glasses frame. In the present invention, the shape of the eyeglass frame is arbitrary, and a nose pad is provided at the center of the eyeglass frame regardless of the shape of the eyeglass frame. The eyeglass frame shown in the figure has rims 1, 1, a bridge 2, a yoke 3, 3, and vines 4, 4, and nose pads 5, 5 for fitting lenses, and the rims 1, 1 are connected by the bridge 2, On the outside of the rims 1, 1, braids 3, 3 are brazed, and the vines 4, 4 are attached to the braids 3, 3 via hinges so as to be foldable.

The nose pad 5 to which the present invention is applied is attached to the tip of a leg which is brazed to the inside of the rim 1 and extends. The brazing position of the legs differs depending on the form of the spectacle frame. For frameless spectacles without a rim, they extend from the bridge connecting the two lenses. Of course, even in the case of an eyeglass frame having a rim as shown in the same figure, or in the case of a nylol frame in which the lower half of the lens is held by a high-tensile thread such as a water thread, a leg is attached to the bridge. May be brazed. On the other hand, instead of brazing, the legs may be integrally formed with the bridge.

FIG. 2 shows a specific example of the leg 6. The leg 6 is made of metal and made of a material having excellent spring properties. The round wire is swaged to reduce a part of the wire diameter, and after bending into a predetermined shape, the claws 7a and 7b are attached to the tips. Is molded. The two claws 7a and 7b form a pair and are formed to have a small thickness so as to be able to bend and deform inward.

FIG. 3 shows a state before the nose pad 5 is engaged with the pawls 7 a and 7 b of the leg 6, and a fastener 8 is projected from the back side of the nose pad 5 as in the conventional case. The fastening device 8 may be integrally formed with a resin material together with the nose pad 5, and a metal fastening device 8 manufactured separately may be embedded. Is provided to penetrate. In some cases, a metal material such as titanium is used as the material of the nose pad, and the fastening device 8 projects to the back side. The shape of the hole 9 is a rectangular through hole, and the claws 7a and 7b are fitted into the hole 9 and the nose pad 5 is attached.

FIG. 4 is an embodiment of the present invention showing the attachment structure of the nose pad 5. The inclined surfaces 10a and 10b are formed on both sides of the tips of the claws 7a and 7b. It is bent and pushed into the hole 9. When fitted in the hole 9, the nail 7a, 7b is restored to its original shape and does not come off the hole 9, but is loosely fitted in the hole 9 and the nose pad 5 is slightly oriented. Can change. That is, as shown in FIG. 5, the cross-section of the state in which the two claws 7a and 7b are fitted in the hole 9 is larger than the two claws, and it is possible to change the direction within the clearance and adapt to the nose. I can do it. As described above, the nose pad attaching structure of the present invention has the following effects obtained by fitting the claw at the tip of the leg extending from the front part into the hole formed in the fastener. Can be done.

[0014]

[Effect of the invention]

 The nose pad attachment structure of the present invention is formed by forming a through hole in the fastener protruding to the back of the nose pad, and fitting the claw provided at the tip of the leg into this hole. It is much simpler than the conventional structure of fitting and screwing. As a result, the number of manufacturing steps is reduced, and the nail is flexed and deformed and inserted into the hole just by pressing the nail into the hole, which is extremely simple compared to the conventional screwing work, and the nose pad can be replaced freely. .
