Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a nose pad and a nose pad for an eyeglass frame.

[0002]

2. Description of the Related Art Referring to FIG. 1, a nose pad of a general metal spectacle frame is composed of a pair of composites which are arranged in a C-shape between the left and right lens holding frames 2 of the spectacle frame. Elliptical plate or oval plate-shaped part made of resin (base material 3)
, The nose contact surface of the opposing surface arranged in a C shape,
It is formed of a dense synthetic resin into a smooth curved surface to improve the feel.

The eyeglass frame shown in FIG. 1 is made of metal. However, in an eyeglass frame in which a lens holding frame is integrally formed of synthetic resin, an edge facing the middle between the left and right lens holding frames is directed in the face direction. It is also well known that the nose surface is formed by slightly extending a plate shape, and this portion is used as a nose pad.

Usually, in the glasses having these nose pads, the bending shape and the opening angle of the pair of right and left temples 14 are adjusted so that the lens holding frame 2 is securely fixed to the face. The upper raised part is to be locked.

[0005]

However, since the nose pad is formed of a hard synthetic resin densely, the nose pad may cause discomfort and pain when pressed on the upper part of the nose for a long time. In addition, there is a problem that when the eyeglasses are removed, a trace of the nose contact surface is formed on the upper part of the nose, which causes discomfort to the wearer.

Also, depending on the state of use of the glasses, there is also a problem that sweat or sebum adheres to the nose contact surface and becomes slippery, and the glasses easily slip down due to their own weight.

Therefore, the present invention solves the above-mentioned problems, and makes the nose pad of the spectacle frame less likely to cause discomfort and pain to the wearer. An object of the present invention is to provide a nose pad and a nose pad that can make it difficult for the frame to slip off the face.

[0008]

In order to solve the above-mentioned problems, according to the present invention, there is provided a pair of nose pads arranged in a C-shape between the left and right lens holding frames of an eyeglass frame. The nose pad of an eyeglass frame in which a pad made of a soft porous material was fixed to the skin contact surface of the eyeglasses.

[0009] Alternatively, in a nose pad for mounting on a skin contact surface of a pair of nose pads arranged in a C-shape between the left and right lens holding frames of the eyeglass frame, the nose pad is an adhesive pad for mounting. That is, a configuration of a soft porous sheet having a surface was adopted.

Alternatively, in a nose pad mounted on a skin contact surface of a pair of nose pads arranged in a U-shape between the left and right lens holding frames of the spectacle frame, the nose pad is a nose pad. It adopted a configuration consisting of a bag made of a soft porous sheet wrapped so as to cover the skin contact surface.

In the above-described invention relating to the nose pad of the spectacle frame, the soft porous material fixed to the skin contact surface of the nose pad alleviates the pressure stimulus applied to the skin above the nose of the wearer due to its flexibility. Even if the nose pad is pressed against the skin for a long time, it does not cause discomfort to the wearer, and the pain of the skin due to the pressure of the nose pad hardly occurs.

In addition, the nose pad having the above-mentioned structure has a hygroscopic property due to the porosity of the pad and has a large frictional resistance, so that it is difficult for the nose pad to slip even if sweat or sebum adheres. Become.

In the invention relating to the nose pad coated with the adhesive, the surface coated with the adhesive is pressed against the skin contact surface of the nose pad so that the pad can be appropriately and easily attached to the nose pad. It can also be attached to eyeglass frames having various forms of nose pads, and prevents the eyeglass frames from slipping off when skin discomfort or sweat etc. adheres to the nose pads as described above. There is an effect.

In the invention relating to the nose pad formed in a bag shape, in addition to the effect of the porosity of the pad as described above, the pad can be attached simply by putting it on the skin contact surface, and can be easily removed. As a result, the nose pad can be cleaned and reused in a clean state after use.
