Description

TECHNICAL FIELD The present invention relates to a front portion structure capable of mitigating the impact when the front portion is impacted by contact with another person when wearing spectacles.

Eyeglasses consist of a front part with lenses and two temples, and the temples are attached to both sides of the front part via joints such as hinges so that they can be folded.
When wearing spectacles, the front part is placed in front of the face through the nose pads, and the temples are engaged with the ears.
By the way, when the front portion is impacted by contact with another person, or when an object such as a ball hits the front portion, the front portion often comes into contact with the face and causes injury.

In particular, children and children who wear eyeglasses may experience an accident such as an injury to the face when the front part is hit by an object or someone hits the front part while playing. occurs.
In addition, a lens is fitted to the rim of the front portion, and the impact may break the lens and cause injury.

Therefore, various spectacle frames have been conventionally known which are capable of mitigating the impact acting on the front portion.
For example, the ``lens mounting structure for spectacle frames'' disclosed in Japanese Patent Application Laid-Open No. 2013-88538 prevents the lenses from coming off even when force or impact in the bending direction is applied to the half-rim type or brow bar type front frame. The spectacle frame has a lens mounting structure that provides a good field of view even when a resin frame or wooden frame is used.

The spectacle shock absorbing mechanism according to Japanese Patent Application Laid-Open No. 2003-215504 can be manufactured with a simple structure, and even if an accidental pressure is applied to the spectacle front frame, this collision energy can be absorbed by the restoring elasticity of the elastic member. It is a shock-absorbing mechanism for eyeglasses.

"Lens mounting structure of spectacle frame" according to JP-A-2013-88538 "Shock absorption mechanism for eyeglasses" according to JP-A-2003-215504

In this way, by alleviating the impact acting on the front portion of the spectacles worn, it is possible to prevent damage to the lenses fitted to the rims and to prevent the front portions from hitting and injuring the face.
By the way, conventional spectacles with a shock absorbing function have a complicated structure, spoil the appearance, and increase the manufacturing cost.
The problem to be solved by the present invention is to solve these problems, and to provide a front portion structure of spectacles which can be manufactured very simply and which is pleasing in appearance.

The spectacles according to the present invention have temples attached to both sides of the front part so that they can be folded, and have a common basic shape. Depending on the design, the front portion of the spectacles may take various forms, but is not limited. In addition, the joint structure of the temples can be freely selected with hinges and the like.
By the way, the front portion constituting the spectacles of the present invention is provided with a cushion material made of soft resin on the back side of the rim.

The rim is composed of an outer rim portion and an inner rim portion. The outer rim portion is made of a hard resin into which a lens is fitted, and the inner rim portion is made of a soft resin with excellent cushioning properties.
By the way, the outer rim portion and the inner rim portion of the rim are integrally formed to form a single unit, and the inner rim portion is sometimes fixed to the outer rim portion with an adhesive.
A recessed groove is formed along the inner periphery of the inner rim portion to form a shape that improves the cushioning properties of the inner rim portion.

The spectacle front part of the present invention has an inner rim part with excellent cushioning properties on the back side of the outer rim part. Therefore, even if an impact acts on the front portion, the cushioning property of the inner rim portion mitigates the impact, thereby preventing the lens from being damaged and the face from being scratched.
At the very least, it is effective in preventing injuries and accidents during play by children and children wearing the spectacles of the present invention.

The front portion of the spectacles of the present invention is composed of an outer rim portion made of hard resin and an inner rim portion made of soft resin. It is not recognized that it is doing so, and the appearance as a front part is not spoiled.
Furthermore, it has a simple structure in which the lens is fitted to the rim of the general front part, and the manufacturing cost does not increase.

FIG. 2 is an enlarged cross-sectional view taken along the line AA of FIG. 1; FIG. 4 is a perspective view showing lens grooves and concave grooves formed in the outer rim portion and the inner rim portion;

FIG. 1 shows an embodiment showing the front structure of eyeglasses according to the present invention, where (a) is a plan view, (b) is a front view, and FIG. 2 is a side view.
In FIG. 1, reference numeral 1 denotes a front portion, 2 and 2 denote temples, and 3 and 3 denote joints.
The spectacles shown in the figure are made of resin, and two paired nose pads 4, 4 are molded in the central part of the front part 1. As shown in FIG.

The front part 1 has a two-layer structure, and is constructed by laminating an outer rim part 5 and an inner rim part 6. The outer rim part 5 is made of hard resin, and the inner rim part 6 is made of soft resin with cushioning properties. there is
The lenses 7,7 attached to the front part 1 fit on the outer rims 6,6 and the inner rims 6,6 do not fit the lenses 7,7.
The outer rim portions 5, 5 and the inner rim portions 6, 6 are connected by a connecting portion 8 provided in the center, and the outer rim portion 5, 5 is a general resin-made spectacle frame.

The front portion 1 having a two-layer structure of the outer rim portion 5 and the inner rim portion 6 is integrally molded by injecting molten hard resin and soft resin into a mold. In terms of appearance, it is formed as one integrated front portion 1 .
Of course, if they come into contact with each other, the inner rim portion 6 formed on the inner surface is a soft layer with cushioning properties, and the outer rim portion 5 formed on the outer surface is hard, and the front portion 1 is composed of this two-layer structure. are doing.

The outer rim portion 5 made of hard resin and the inner rim portion 6 made of soft resin are integrally molded. It can also be fixed to the outer rim portion 5 made of resin via an adhesive.
As shown in FIG. 3, which is an enlarged cross-sectional view taken along the line AA of FIG. 1, a lens groove 9 is provided along the inner peripheral surface of the outer rim portion 5, and a convex portion formed on the outer periphery of the lens 7 is the lens. The lens 7 is attached to the outer rim portion 5 by fitting into the groove 9 . The outer rim portion 5 and the inner rim portion 6 are joined with a step.

A groove 10 is formed along the inner periphery of the inner rim portion 6 made of soft resin, and the groove 10 can be contracted when an external pressure P acts on the inner surface 11 . The inner rim portion 6 made of a soft resin has a cushioning property and is compressed and deformed by the action of the external pressure P, but by providing the concave groove 10, it is compressed and deformed by a smaller external pressure P and acts on the front portion 1 of the spectacles. It can soften the impact.

FIG. 4 is a perspective view showing lens grooves 9 and concave grooves 10 formed in the outer rim portion 5 and the inner rim portion 6. FIG. A lens groove 9 is formed on the entire inner periphery of the outer rim portion 5, and the outer peripheral convex portion of the lens 7 is fitted and attached.
On the other hand, the groove 10 formed on the inner circumference of the inner rim portion 6 may be formed not on the entire inner circumference but on a part of the inner circumference as shown in the figure. Of course, it is also possible to provide along the entire inner circumference.

The cross-sectional shape of the concave groove 10 is not particularly limited, and is not limited to the inverted U-shaped cross section shown in FIG. Also, a plurality of narrow grooves 10, 10, . . . can be provided.
If the recessed groove 10 is to be formed in a part of the inner rim portion 6, it is preferable that the region is located above the inner rim portion 6 as shown in FIGS.
