Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a resin vine for spectacles that can be easily adjusted in length and fits to a temporal region or an auricle of a wearer.

[0002]

[Prior art]

 Conventionally, temples made of resin are made of elastic resin as shown in Fig. 6 without using a metal core, and are integrally molded from the hinge frame to the modern end. The number-piece part and the core metal are made of metal, and are molded by resin coating, or a temple or the like inserted and fixed in a sheet material processed and cut has been generally used.

[0003] Further, as proposed in Japanese Utility Model Laid-Open No. 6-78926 (not shown), there is a modern forehead that can adjust the length of a temple.

[0004]

[Problems to be solved by the invention]

 However, in the temple as shown in Fig. 6, the fitting property is good, but the bending condition of the modern part is formed at the resin molding stage, and it is necessary to make adjustments to suit each individual wearer. Difficult and at the retail stage, in most cases inoperable.

In the case of FIG. 7, it is possible to perform one or two bending modifications at the ear hook portion, but since the core is inserted as a whole, even if the elastic resin When using as a temple member, the restoring force is impaired, and the fitting property is not good. In addition, because of the good lubricity inherent to the resin in both cases, slippage occurred in the ear-hook portion, and it often slipped relatively easily by movement or depression.

In the case proposed in Japanese Utility Model Laid-Open No. Hei 6-78926 (not shown), the above-mentioned problems have been solved to some extent. We are trying to solve the problem by using a soft elastomer as the material and adjusting the length of the temple to suit each wearer.

[0007] However, according to this proposal, the bent shape of the modern part is determined and molded from the beginning, and the length for inserting the core is shortened, so that the modern and the temple are easily pulled out. In order to compensate for this, it has been proposed to use a knurling or a stop spring, and to heat-weld the fore edge for final fixing, but this requires skill and requires a complicated process.

[0008]

[Means for Solving the Problems]

 Therefore, in the present invention, in order to solve the above-mentioned problem, the rear end of a slightly curved rod-shaped elastic resin temple having a hinge piece integrally formed at the front end is provided with a modern thermoplastic elastomer. The end of the metal core to be inserted in the longitudinal direction is buried and fixed in the longitudinal direction, and the thermoplastic elastomer modern that serves as the ear hook portion has a rear end of the elastic resin temple of 15 mm from the front end to the rear end. Adjustable length resin fitting, characterized in that a large-diameter hole that can be inserted up to 25 mm and a subsequent hole with a small diameter for inserting the metal core are continuously connected to the vicinity of the modern rear end. By using a vine, a super engineering plastic is used for the rod-shaped elastic resin temple, and a styrene-based thermoplastic elastomer is used instead of the thermoplastic elastomer modern. , It attempts to resolve the above problems.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of an embodiment of the present invention, in which an elastic resin temple 2 and a hinge piece 1 are integrally formed at the front end thereof, and the elastic resin temple curves slightly outward. It has a substantially rod-like shape, and an anchor portion 8 for preventing the core bar 3 from slipping out of the core 3 to be inserted into the modern 4 is embedded and fixed to the rear end portion 7, and the modern 4 is a thermoplastic elastomer, preferably a thermoplastic elastomer. Is made of a styrene-based thermoplastic elastomer, and has a hole 5 having a large diameter of 15 mm to 25 mm into which the rear end 7 of the elastic resin temple is inserted and whose insertion length can be adjusted. A small-diameter hole 6 for inserting the metal core 3 is provided up to the vicinity of the modern rear end. Even at the time of factory shipment, the modern part is inserted as it is and is straightened without bending. Shipped as it is and the size of the wearer at the store It can be used immediately just by adjusting the bending on the spot according to.

[0011] By using a thermoplastic elastomer for the modern portion, the temple and the modern once fit into each other due to frictional contact between the temple resin and the modern, so that they are not easily displaced and hardly come off. In addition, if the modern is folded into the shape of an ear, the core 3 inserted in the modern will not bend easily and will not come off from each other. Also, there is no need for means such as applying heat and bonding the modern and temple, It can be easily done without using extra parts.

In addition, by using a styrene-based thermoplastic elastomer as a modern material, the friction coefficient is further increased, and the appearance is hardly changed even if it is bent many times, and the deterioration is small. This is very effective also for amateurs who wear glasses and re-bend the modern part, and most people can adjust the modern part without failure.

FIG. 2 is a plan view of the present invention, which can be extended by about 25 mm in a shape at the most extended stage, and has a good flexibility in bending to a certain extent even when bending a modern.

FIG. 3 is a plan view of the present invention, showing the shape at the stage where it is most contracted and adjusted to fit a person with a small head and face.

FIG. 4 is a schematic view from the side where the vine of the present invention is mounted. The distance between the upper and lower positions of the base of the auricle 9 and the face is varied depending on the person, and subtle adjustments are made depending on the type of resin material. With changes, it is becoming more difficult at retailers, etc., but according to the present invention, the distance from the face can be adjusted by the length of inserting the temple modernly, and the upper and lower positions can be easily adjusted by modern bending processing Adjustment is possible.

FIG. 5 is a plan view of another embodiment of the present invention, in which a super engineering plastic is used for an elastic resin temple, which can be expanded outward to an angle of about 45 degrees, This is much easier to spread than the normal 25-degree spread of the spring hinge, and it is easy to hang, and it fits the face with moderate elasticity when worn normally.

FIG. 6 is a perspective view of a conventional temple integrally molded from the hinge piece to the modern end by using an elastic resin without using a metal core, as described above. Although it is ensured, the ear hooks are shaped at the molding stage, so the length adjustment is not effective, and the bending degree of the ear hooks can hardly be adjusted. There is a drawback that it shifts immediately when you go or exercise.

FIG. 7 shows another conventional example in which, as described above, the hinge piece and the core are made of metal and are molded by resin coating or are inserted into a sheet material after machining and cutting. FIG. 2 is a perspective view of a resin temple of the present invention. Since the core is inserted into the whole, bending can be performed on the ear hook portion, but it lacks elasticity and is slippery. When exercising, it slips off easily and the fitting is not good.

[0019]

[Effect of the invention]

 As described above, the adoption of the resin crane according to the present invention makes it easier to spread the vine when wearing eyeglasses, and also adjusts the length by specially using the heat fusion method and other parts. There is no need to make it, it is simple, it can easily bend modern parts, and it can be worn without shifting even intense movements such as sports, giving a new feeling of fitting and wide use. Becomes possible.
