DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle pad for supporting spectacles on the nose by hitting the nose.

[0002]

2. Description of the Related Art Eyeglasses are intended to make refraction and dysregulation of an eye similar to those of normal vision, or to remove harmful ultraviolet rays and sun rays, and to prevent foreign matter such as wind and dust. It is equipped in front of the eyes to prevent it from entering the eyes. The spectacles for this purpose are important to adjust the distance from the eye and the angle at which the ray enters the eye so that the wearer is best able to see the object through the spectacle lens.

[0003] For this reason, in general, eyeglasses are arranged such that the lower end of the frame is placed on the bridge of the nose, the tip of the temple (vine) is fixed to the upper part of both ears, and the lens portion is fixed in front of the eyes. However, since the person wearing the glasses has a variety of different skeletons, simply fixing the temples may cause the frame to be displaced due to the vibration accompanying the operation of the person wearing the glasses. For this reason, a spectacle pad is usually attached to the frame part corresponding to the bridge of the nose.

An example of this eyeglass pad is shown in FIG.
Indicated by The spectacle pad 1 is attached to a portion of the frame 3 of the spectacles 2 corresponding to the nose via the pad arm 4, and can be supported on the nose by being brought into contact with the nose. It has been like that. The material of the spectacle pad is a material that does not change into components contained in sweat, cosmetics, and the like, and is generally made of a synthetic resin.

Here, the pad arm 4 usually uses a relatively soft metal thin wire which is curved like a spring.
The elasticity serves to fix the spectacle pad to the nose, but does not tighten the nose bridge even when the spectacle pad 1 hits, and fixes the frame 3 by applying the weight of the frame 3 and the lens 5 to the nose bridge. For this purpose, the bending portion is finely adjusted with radio pliers or the like in accordance with the width of the bridge of the nose of the person wearing the glasses 2 to adjust the pressure at which the glasses pad 10 sandwiches the nose. That is, the adjustment of the contact with the nose was almost performed only by adjusting the pad arm 4. Therefore, when the adjustment of the pad arm 4 is out of order due to an impact or the like, or when the pad arm 4 does not fit the nose, the adjustment is performed by widening or narrowing the bent portion of the pad arm 4.

As described above, the eyeglass pad 1 sets the lens angle and distance that are optimal for the eyesight of the person wearing the eyeglasses 2 in relation to each other.

However, this conventional eyeglass pad 1 is made of synthetic resin in order to improve the coldness and rigidity of metal, but lacks shock absorbing power. If the wearer receives an impact, the eyeglass pad may hit the nose violently and the nose may be damaged.

Further, even if the weight is reduced and the burden on the nose is reduced, the plate-like spectacle pad 1 is in a state of pressing the nose because the elastic force of the pad arm 4 is transmitted to the nose as it is, and the nose is pressed. When it is used, there are inconveniences such as that the pressed part of the bridge of the nose becomes painful and that the spectacles pad 1 remains.

In order to eliminate these problems, it is known to use a soft synthetic resin cushion portion or a soft synthetic resin cushion pad in which liquid or air is sealed. For example, the actual opening 62-69
Reference numeral 211, Japanese Utility Model Laid-Open No. 7-32626 is a pad in which gas is injected to form a cushion portion.

[0010] In these, the gas injected into the cushion portion moves according to the shape of the nose, and the nose can be gently pressed and held without any gap (see Japanese Utility Model Application Laid-Open No. 62-6921).
1). In addition, the presence of the air reservoir functions as a cushioning material, and the nose pad touches the ears or the nose with a soft sensation without irritation and exerts the effect of preventing the occurrence of pain. (Actually open 7-32626).

In these, the pad portion uses one kind of material. In addition, both are filled with gas or air. The material of the pad portion is made of a soft synthetic resin having flexibility, and the air inside moves according to the shape of the nose, so that the nose is pressed and held without gaps.

[0012]

However, since the cushion for enclosing an amount of air that moves in accordance with the shape of the nose needs to have a certain thickness for its function, a person wearing the spectacles can pass through the spectacle through the object. When viewing, there is a risk of visual impairment at close range. Also, when the person wearing the padded glasses is viewed from the front, the cushion portion at the nose may be obstructive.

Further, from a functional point of view, in view of the amount of gas sealed in the cushion portion and the function of being flexible when the synthetic resin bag for sealing the gas hits the nose, the synthetic resin bag is deformed. A resin bag is required to have a small thickness and be flexible as a property of the resin. In this way, a bag made of a thin and flexible synthetic resin is considered to have relatively low mechanical strength and shock resistance for transmitting the weight of the lens and frame to the nose, so that the glasses can be fixed in place. I was worried about fixing and shock during intense sports and work. In addition, since an operation of injecting air after forming the cushion portion is required, the operation cost may be increased.

The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, have arrived at the present invention.

[0015]

The gist of the eyeglass pad according to the present invention is as follows. The eyeglass pad is fixed to a contact portion of the frame of the eyeglass with the nose, and is brought into contact with the nose to put the eyeglass on the nose. In the supporting spectacle pad, while a cavity of a predetermined size is provided between the hard plate piece and the soft plate piece, formed by joining the hard plate piece and the soft plate piece,
One side of the soft plate is in contact with the nose. Here, the hard plate piece refers to a plate piece having a certain shape and is not deformed, and the soft plate piece refers to a plate piece that is more easily deformed than the hard plate piece.

Such a spectacle pad according to the present invention comprises:
It is formed to include a pad plate, and is attached to the frame so as to be supported by a pad arm fixed to the frame of the glasses. The spectacles with the spectacle pads attached are supported on the nose such that the spectacle pads abut the nose. As for the spectacle pad in contact with the nose, the pressure applied to the nose from the spectacles is reduced by deforming the soft plate piece to some extent. Further, the soft plate piece is deformed to some extent, so that the feel to the nose becomes soft.

The gist of the spectacle pad according to the present invention is as follows. In the spectacle pad, the cavity has an opening, and the cavity has a space around the spectacle pad through the opening. To be continuous.

The spectacle pad according to the present invention has the following features.
Since the cavity has an opening, and the cavity is continuous to the space around the eyeglass pad through the opening, air is not sealed in the cavity, and the air passes through the cavity and the surrounding space. It will circulate. Since air is not sealed in the cavity, the soft plate piece is easily deformed, the load on the nose from the glasses is reduced, and the feel to the nose is softer.

The gist of the spectacle pad according to the present invention is as follows. In the spectacle pad, the hard plate piece and the soft plate piece are partially fixed and joined to form a hard plate. The portion other than the fixed portion between the piece and the soft plate piece forms the hollow portion, and the soft plate piece can swing about the fixed portion as a fulcrum.

Such a spectacle pad according to the present invention comprises:
Since the soft plate piece can swing about the fixed portion as a fulcrum, when the soft plate piece is brought into contact with the nose, the soft plate piece is deformed corresponding to the nose. Since the soft plate deforms corresponding to the nose, the soft plate deforms more flexibly, the load on the nose from the glasses is reduced, and the feel to the nose is softer. Further, since the amount of deformation of the soft plate piece is large, it is possible to cope with various shapes of the nose.

The gist of the spectacle pad according to the present invention is that the soft plate piece has elasticity in the spectacle pad.

The spectacle pad according to the present invention has the following features.
Since the soft plate piece can elastically swing with the fixed portion as a fulcrum, when the soft plate piece is brought into contact with the nose, it is elastically deformed corresponding to the nose. Further, since the soft plate piece is elastically deformed, it is more flexibly deformed according to the shape of the nose.

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an eyeglass pad according to the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a spectacle pad according to the present invention. The spectacle pad 10 is a spectacle pad for supporting spectacles on the nose by being brought into contact with the nose, and has a cavity of a predetermined size between the hard plate piece 12 and the soft plate piece 14. While the portion 16 is provided, the hard plate 1
2 and the soft plate piece 14 are joined together,
The soft plate piece 14 side is a spectacle pad in contact with the nose.

Here, the hard plate piece 12 is not particularly limited as long as it has a function of dispersing the weight of the lens and frame of the spectacles and applying a load to the nose.
Is not particularly limited as long as it comes into direct contact with the nose softly, but is preferably selected in consideration of workability, feel, weight, price, and the like.

More specifically, the material of the hard plate piece 12 used on the fixed side may be a commonly used material as long as it has strength enough to hold the weight of the lens and the frame. However, for example, a synthetic resin such as a polyethylene resin or an acrylic resin, or a mesh-like metal is preferable.

Further, the material of the soft plate piece 14 used for the portion corresponding to the nose is rubber-like material which is easy to process, has a soft touch compared to metal or the like, is lightweight, and is inexpensive to manufacture. An elastic synthetic resin is preferably used. Specifically, vinyl chloride resin, silicone resin,
There is a synthetic resin such as a styrene resin. In particular, a silicone resin is preferable because it has cold resistance, heat resistance, and water repellency, and is chemically stable.

The shape of the hard plate piece 12 and the soft plate piece 14 is not particularly limited, but is so large that it does not obstruct the field of view and does not disturb the appearance of the frame. A shape having no corners, for example, an elliptical shape is preferable.

Next, a method for producing the spectacle pad 10 according to the present invention will be described with reference to an example. The hard plate piece 12 is formed of, for example, a hard synthetic resin in a shape including the pad plate 18 embedded therein. Specifically, for example, a slurry-like thermoplastic resin is poured around the pad plate 18 and molded while cooling. On the other hand, the synthetic resin used for the soft plate piece 14 is formed to have the same outer diameter as the shape of the synthetic resin of a hard material.

The synthetic resin used for the soft plate piece 14 is bonded or crimped around the periphery thereof in a partially opened state together with the hard synthetic resin containing the pad plate 18. The adhesive used for bonding is not particularly limited as long as it does not harm the human body and does not react with secretions such as sweat, such as an epoxy-based adhesive, a polyurethane-based adhesive, and a silicone-based adhesive. In the case of pressure bonding, it is necessary to set the temperature in relation to the glass transition temperature between the synthetic resins.

The method of joining the hard plate piece 12 and the soft plate piece 14 is basically not particularly limited as long as a part of the hollow portion is provided. It is desirable that the elasticity of the soft plate piece 14 is maintained while not peeling.
