JPS595847Y2 - Improvement of eyeglass frames - Google Patents

Description

[Detailed description of the invention] This invention relates to improvement of eyeglass frames, and more specifically, to eyeglass frames consisting of lenses, frames, and temples, in which an elastic member is interposed between the frame and the temples. It is.

Conventionally, various proposals have been made and implemented regarding eyeglass frames.

According to this type of glasses, the temples of the glasses are basically pivoted to the frame with pins, etc., and suspended from the ears, so that the temples of the glasses are suspended from the ears during strenuous exercise such as sports. In addition, since the length of these temples varies depending on the person who wears the glasses, users can combine the temples, shapes, colors, etc. to suit their own needs. It takes a lot of effort to choose glasses to wear.

In order to eliminate these drawbacks, an elastic member such as a coil spring or leaf spring is inserted between the frame and the temple, and the head is held between the temples by the inward repulsive force of this elastic member. has been devised.

However, since these elastic members are all made of metal, they suffer from corrosion due to sweating and their repulsive force deteriorates after long-term use.Furthermore, the structure of the frame and temples is complicated, which increases manufacturing costs. There are also drawbacks to raising it.

Furthermore, some eyeglasses have been devised that use soft plastic, resin, or rubber instead of metal elastic members, but their structure is simply a thin sheet of plastic, resin, or cylindrical rubber bonded with adhesive. Since the adhesive is attached to the temple portion or lens frame through the adhesive, it is expected that the adhesive itself may fall off due to deterioration, and the range in which the repulsive force can be applied is also disadvantageously narrow.

As a result of repeated efforts and trial production to overcome the various problems mentioned above, the inventor of the present invention has developed a synthetic resin material with excellent corrosion and abrasion resistance in place of the coil springs or leaf springs. In addition, this composite resin material is V-shaped to easily generate repulsive force, while a U-shaped protrusion is formed at the end of the frame body, and a U-shaped protrusion is also formed at the tip of the temple. A similar U-shaped body is formed, the U-shaped body of the temple part is fitted into the protrusion of the frame main body, and the V-shaped element is inserted between this protrusion and the U-shaped body of the temple part. It was found that it is sufficient to interpose the pin member between the two parts and integrally support the pin member.

Therefore, the object of the present invention is to form a triangular prism having a predetermined apex angle using a resin material with high elasticity and restoring force such as polypropylene, and to form a triangular prism having a predetermined apex angle on one side wall of the triangular prism. A V-shaped groove with a wider angle than the apex angle is carved into the triangular prism body, and a locking protrusion is protruded from the bottom corner of the triangular prism body to form a V-shaped element. A U-shaped locking portion is provided protrudingly on the portion, and the end portion of the vine portion is bent into a U-shape.
The end of the temple part is fitted into the locking part of the frame main body, and the element is interposed between the locking part and the end of the temple part with the groove facing outward, and the element is further inserted into the locking part. The present invention is characterized in that the end portion of the temple portion, the end portion of the temple portion, and the element are integrally supported by a pin member.

Other objects and advantages of the present invention will become more apparent from the detailed description below.

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates glasses, and these glasses 1
0 basically consists of a frame body 12, a lens 14 attached to the frame body 12, and a temple part 16 rotatably supported at the end of the frame body 12.

The frame body 12 consists of a frame portion 18 and a locking portion 20 formed by bending a flat plate protruding from the right end of the frame portion 18 into an inverted U-shape in cross section (see Fig. 2). , the upper surface part 22 and the lower surface part 24 of the locking part 20 have insertion holes 2B for pins 26,
2B is drilled.

The temple portion 16 that engages with the locking portion 20 is composed of a metal strip 30 whose tip end is shaped like a U-shape in cross section, which is slightly smaller than the locking portion 20. Holes 3 corresponding to the holes 28 and 28 of the locking part are provided in the upper and lower surfaces of the shape.
2.32 and a notch 33 is cut in the side wall of the tip end of the strip 30 in order to house and arrange a V-shaped element to be described later (see FIG. 3).

The temple portion 16 is designed to fit inside the locking portion 20, and an element 34 is further interposed in the abutting portion between the locking portion 20 and the temple portion 16.

This element 34 is made of a resin material with high elasticity and restoring force such as polypropylene, and as can be easily understood from FIG. A V-shaped groove 38 having a wide angle β is formed, and the overall shape is V-shaped, and a hole 40 for inserting the pin 26 is bored near the top.

Note that there are protrusions 4 on the upper and lower parts of this element 34, respectively.
2 and configured to lock onto the outer end of the locking portion 20, this element will not move in response to the rotation of the temple portion, which is more preferable (see FIG. 6).

When assembling these glasses, the element 34 is attached to the temple part 16 so that the hole 40 of the element 34 fits into the holes 32, 32 of the U-shaped part of the temple part 16, and the groove 38 is directed outward. The temple portion 16 and the element 34 are fitted together into the locking portion 20 .

At this time, the hole 28.28 is fitted in a straight line with the holes 32, 32 of the temple part and the insertion hole {L40 of the element 34, and therefore the pin 26 is fitted in the hole 28.2B, the hole 32
, 32, and the temple portion 16 is inserted into the insertion hole 40 and pivotally supported on the frame body 12.

It goes without saying that the left side of the frame body 12 is symmetrical to the right side due to the structure of the eyeglasses.

The present invention is constructed in this way, and its function is explained as follows: When the glasses are not in use, the pair of right and left temples 16 are in a crossed state, but when the glasses are in use, the temples 16 are crossed. 16 are opened outward from each other and held in the head.

Due to the function of this temple, the side walls forming the groove 38 of the element 34 come close to each other, but on the other hand, the angle β formed by the side wall of the groove 3B is wider than the angle α at the top. Moreover, since a repulsive force is generated due to the unique properties of the element made of an elastic member, the pair of temple portions 16 clamp the head.

As described above, according to the present invention, the U-shaped locking portion protrudes from the end of the frame body, and the end portions of the temple portions are bent into a U-shape and fit together, and the resin body is assembled. Since the square-shaped elastic member consisting of the above structure is interposed between the frame body and the temple portion, the glasses can be supported on the head by utilizing the repulsive force having an extremely wide range of action.

Therefore, even if the glasses wearer does strenuous exercise, the glasses will not fall off, and since the glasses are not fixed to the ears, the glasses will not fall off due to the length of the temples, regardless of the size or shape of the head. There's no need to make a choice.

In addition, by selecting the elastic member and widening or narrowing the angle β of the groove, it is possible to obtain glasses with a supporting force suitable for the user. First, it provides various excellent practical values when holding eyeglasses.

The preferred embodiments of the present invention have been described above in detail with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. Of course there is.
