JP7045077B2 - Connecting the nose pad and both nose pads of the eyeglass frame - Google Patents

Description

The present invention relates to a nose pad pad attached to the center of the front portion of the eyeglass frame and a connection between both nose pad pads.

The shape of the eyeglass frame is diversified, but its basic form consists of a front part and two vines (temples), a rim on which the lens fits in the front part, and a nose pad in the center. Is installed. By the way, when wearing glasses, the nose pad pads can be applied to both sides of the nose to support the front portion, and the vine can be locked to the ear.

The nose pad is mainly made of resin, and its shape is generally substantially oval, and the front portion is supported by abutting so as to sandwich both sides of the nose. There are various shapes of the nose, so the legs are bent and the nose pad is adjusted so that it touches both sides of the nose correctly.
However, there are many cases where it is not possible to stably support the front part due to lack of fit just by touching both nose pads on both sides of the nose. In particular, if you exercise and move your body, the front part will be out of position.

FIG. 6 shows a conventional general metal eyeglass frame. In the figure, (a) shows the front part and (b) shows the vine, and two nose pad pads (c) and (c) are attached in pairs to the central part of the front part (a). ing.
With such nose pad pads (c) and (c), the front portion (a) cannot be stably supported. There is a risk of misalignment when moving the body. In particular, it is not possible to deal with the impact acting on the front part (a).

Even in the past, various techniques related to the nose pad have been considered. For example, the "attachment structure of the nose pad" according to Japanese Patent Application Laid-Open No. 2012-053319 is made of a soft resin for the nose pad, the shape of which is approximately semi-circular or approximately elliptical, and both sides form smooth curved surfaces. There is. A large space with an open cut and a small space behind it are continuously provided inside, and the legs have a fastening part and a mounting part that are press-fitted to the back of the front part and fixed, and the mounting part is roughly The metal wire curved in an S shape is also provided with a matching portion at the tip, and the matching portion is press-fitted into the small space of the nose pad.

In this way, the nose pads attached to the front portion of the glasses have a form in which two pairs are formed, and these nose pads are in contact with both sides of the nose to support the front portion. However, there is also known a nose pad that has a shape curved in a substantially chevron shape as a form of the nose pad, and has a continuous main pad portion that abuts on both sides of the nose and an auxiliary pad portion that abuts on the instep of the nose.
Such a roughly chevron-shaped nose pad does not shift the position of the front part, but does not completely fit the shape of the nose when wearing glasses, which makes the wearing feeling worse.

As described above, the conventional nose pad has the above-mentioned problems. The problem to be solved by the present invention is these problems, and the front portion is stably supported without being displaced, and the fit is excellent so that the impact acting on the front portion can be dealt with. Provide a nose pad.

The form of the eyeglass frame according to the present invention is free, but two nose pad pads are attached in pairs to the central portion of the front portion. If the front part has a rim to which the lens fits, a nyroll frame with a half rim on the upper side and a high tension thread such as water thread on the lower side to hold the lens, or connecting both lenses without having a rim In some cases, it is screwed directly with a member and configured as rimless glasses with a twist on the outside.

The present invention has a structure in which a connection is interposed between the two nose pad pads attached to the front portion. The joint has a substantially chevron-curved shape, and the material is soft resin. Therefore, the joint is flexible and has some elongation.
Connecting portions are provided at both ends of the connecting portion, and can be connected to the left and right nose pad pads via the connecting portion.

Here, the specific form of the connecting portion is not limited, but in general, a hole is penetrated into the connecting portion, and a projecting piece protruding from the back surface of the nose pad is fitted in the hole, and the projecting piece extends from the front portion. It fits into the opening of the box foot at the tip of the leg and is screwed. That is, they are connected and attached by fitting them into the protrusions of both nose pads, but if the connection is unnecessary, they can be removed by removing the nose pads from the box legs.
On the other hand, it is also possible to form a key instead of providing a hole in the connecting portion, and to connect the key by locking the key to a projecting piece protruding from the back surface of the nose pad.

The connection of the present invention is attached by connecting to both nose pad pads. Therefore, the area in contact with the nose is greatly expanded to support the front part by interposing a connection between the left and right nose pads, and the front part is stably supported without being displaced. Compared to the conventional nose pad, the fit with the nose is greatly improved, and the front part is less likely to shift even when the body is moved. In addition, it is excellent in the effect of alleviating the impact when an external force acts on the front part.

The connection is not made of the same material as the nose pad, but is made of soft soft resin, which reduces the impact on the front part, improves the fit with the nose, and makes the glasses more comfortable to wear. ..
On the other hand, the connection is connected between the two nose pads, but it can be removed when it is not needed, and therefore it can be replaced with a new connection when it becomes dirty.
