Abstract

PROBLEM TO BE SOLVED: To enable the stable wearing of spectacles by forming pads at the front ends of planar deflectable and deformable arms and curving the front ends of these arms inward. SOLUTION: The central part of a front frame 1 is provided with the pads 7. These pads 7 are formed at the front ends of the arms 10 extending and curving downward from the connecting parts 9 of both rims 8, 8. The pads 7, 7 exist symmetrically to the center line at the front ends of the arms 10, 10 curving to a substantially arc shape. Resins having high elasticity are used for these pads. The pads 7 are molded integrally with the planar arms 10 and are molded simultaneously with the front frame 1. A highly elastically deformable material is used for the resin constituting such spectacle frame so that the pads 7 are fitted to the nose by the deflection and deformation of the arms 10. The front ends of the temples 2 of the spectacle frame curve inward.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle frame capable of stably wearing spectacles and a nose pad thereof.

[0002]

2. Description of the Related Art A spectacle frame is provided with a nose pad at a central portion thereof to support a front portion of the spectacles. Conventionally used nose pad is attached to the tip of the leg brazed to the inside of the rim, but in this case, the nose pad can be adapted according to the shape and height of the nose. The orientation can be changed within a certain range.

[0003] However, the nose pad is not elastic, and the leg supporting the nose pad is not elastic.
If you move your body suddenly, the front of the glasses will rise, and the nose pad may move away from your nose. Therefore, even if the nose pad hits the nose again, the position of the glasses changes and the glasses are displaced. On the other hand, the conventional nose pad requires a lot of man-hours, such as brazing the leg to the inside of the rim and providing a box at the tip of the leg for fixing the nose pad.

Of course, in the case of a resin frame, the nose pad is molded at the same time as the front part, and no special man-hour is required for manufacturing the nose pad. There is no sex at all.

[0005]

As described above, the conventional nose pad of the eyeglass frame has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a spectacle frame which can be stably worn by spectacles and a nose pad thereof.

[0006]

The nose pad of the present invention is formed by using a resin material having high elasticity, and a substantially elliptical nose pad is provided at the tip of an arm which extends from the inside of the rim. Has formed. The nose pad surface faces diagonally inward and rearward, and if an external force acts on the nose pad surface, the curved arm can deform and bend. The nose pad may be attached to the center of the front part by screws or fixed by screws, but is generally formed simultaneously with the front part.

On the other hand, the crane of the spectacle frame is also made of a resin material having high elasticity, and is attached to both sides of the front part so as to be foldable via joints. The tip of the vine is bent or curved in a substantially "F" shape so as to be hooked on the ear, and further slightly curved inward. Therefore, the tip of the vine comes to hold the head,
The glasses are stabilized in combination with the bending of the nose pad. Here, the eyeglass frame and the nose pad of the present invention are not necessarily limited to a resin material having high elasticity, but may be made of a metal material or another material. Less than,
Embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 shows an embodiment of an eyeglass frame according to the present invention, which shows sunglasses. The sunglasses shown in the figure are made of a resin frame, and vines 2 are attached to both sides of a front frame 1 integrally formed.
The vine 2 can be folded through the. Front frame 1
A sphere 4 functioning as a shaft is provided on both sides of the, and a bearing 5 is fitted to the sphere 4 to connect the crane 2.

A hood 6 for protecting eyes from dust and the like is formed on a side portion of the front frame 1, and a joint portion 3 of the crane 2 is fitted into a notch of the hood 6. The above sphere 4
The folding direction of the crane 2 is determined by the notch formed in the hood 6 because the bearing 5 that merely fits into the hood 6 cannot determine the folding direction of the crane 2.

A nose pad 7 is provided at the center of the front frame 1. The nose pad 7 extends downward from the connecting portion 9 of the rims 8 and 8 and is formed at the tip of a curved arm 10. FIG. 2 shows a central portion of the front frame. The nose pads 7, 7 are located symmetrically at the tips of the arms 10, 10 which are curved in a substantially semicircular arc shape, and a resin having high elasticity is formed. Used. The nose pad 7 is integrally formed with a plate-shaped arm 10 and is manufactured as an independent component separately from the front frame 1 and can be bonded or screwed to the connecting portion 9. Simultaneous molding.

By the way, the resin constituting the glasses frame is made of a material which is rich in elastic deformation so that the arm 10 bends and deforms so that the nose pad 7 can fit into the nose.
For example, polyphenylsulfone is suitable. Polyphenylsulfone at a temperature of about 350 ° C. to 420 ° C. for about 1000
by adding a pressure of kg / cm ² ~3000kg / cm ² by injection molding, manufactured by Aniringu at then about 160 ° C. to 200 DEG ° C.. Of course, it is possible to use a metal or other suitable material having high elasticity. And arm 1
The length from the base of 0 to the tip of the nose pad is about 25m
m, and the deflection of the nose pad 7 is sufficiently large.

If a pressure P acts on the nose pad 7, the arm 10 can flex and deform. The nose pad 7 is provided with a contact surface on the inside rear side, so that the arm 10 bends, so that not only the nose pad 7 fits into the nose, but also the position of the front frame 1 in the front-rear direction is adjusted. Since the tip of the vine 2 of the eyeglass frame of the present invention is curved inward, when wearing the eyeglasses, the cradle 2 holds the back of the head as shown in FIG.

The crane 2 is also formed using the resin described above.
Therefore, it can be adjusted to hold the back of the head with high elasticity. Vertical grooves are formed in the middle portion of the crane 2, and these vertical grooves promote bending deformation of the crane. In the joint structure of the crane 2, the bearing 5 is fitted around the spherical body 4, and the bearing 5 abuts only on the upper and lower ends of the spherical body 4, so that the crane can be detached from the spherical body 4 by an external force. Of course, a conventional hinge can be freely used as the crane joint of the present invention. As described above, the eyeglass frame of the present invention uses the material for the nose pad which is rich in elastic deformation, has a contact surface on the inside rear at the tip of the curved arm, and the vine has the tip portion. Is curved inward, and the following effects can be obtained.

[0014]

The eyeglass frame of the present invention is made of a resin material having a high elasticity, and its nose pad is formed in the shape of a plate and is formed at the tip of an arm which is bent and deformed. The glasses you wear are stable. The tip of the vine is curved inward and fits like holding the head, so that the glasses do not shift even if a sudden movement is made. Further, the nose pad provided at the center of the front frame is formed at the tip of the curved arm, and can be formed simultaneously with the front frame, which facilitates manufacture.
