Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adjustable clinger pad for synthetic resin eyeglass frames, and its object is to provide a clinger pad whose angle can be adjusted to suit the wearer's nose bridge. To provide a synthetic resin eyeglass frame equipped with a pad and an arm for supporting the pad.

Another object of the present invention is to provide a synthetic resin eyeglass frame in which the strap arm supporting the linger pad never falls off the synthetic resin rim frame.

Another object of the present invention is to provide a sturdy and smart synthetic resin eyeglass frame that will not break due to metal fatigue even if the joint between the linger pad and the rim frame is repeatedly twisted. be.

In recent years, a nose pad type called "klinger pad" has become widely used for metal frame glasses. This nose pad method called Clinger Pad is made by attaching a resin pad to the tip of an arm made of metal wire via a holder box, and placing the other end of the arm near the nose bridge surface of the left and right rim frames. It is welded together and is very popular because it can be accurately fitted to the bridge of the wearer's nose. Therefore, there has been a demand for the use of such clinger pads in synthetic resin eyeglass frames, and in fact, synthetic resin eyeglass frames equipped with clinger pads as shown in Figure 4 have been proposed. It's starting to feel like this. However, in this case, the undercut metal wire arm tip 21' is heated and press-fitted into the resin of the rim frame 1', thereby supporting the pad 3'. As a result, an unsightly burr is formed at the point P where the arm tip 21' is press-fitted, and the fixation of the arm tip 21' tends to loosen due to the external force applied to the arm 2' when adjusting the angle or wearing it, so it is difficult to remove it from the base. Failures such as falling or the arm 2' spinning idle around its tip 21', making it impossible to maintain the proper position of the pad 3', were unavoidable.

The present invention was made in view of the above-mentioned difficulties in adopting Clinger pads for synthetic resin eyeglass frames, although they were popular among eyeglass wearers. A corrosion-resistant band-type special arm is used as the material for the arm that connects the linger pad and the rim frame, and a tie hole is drilled at the base of the arm and the hole is buried in the resin material of the rim frame. In addition to eliminating the drawbacks of the conventional method, it is also possible to go one step further and, if desired, adjust the distance between the pad and the rim so that the distance between the lens and the corneal apex on the pupil surface is the optimal distance. This is what I did.

Therefore, the configuration of the present invention will be explained based on an illustrated embodiment: A spectacle frame F molded from a synthetic resin;
It is made of a material that can easily correct twisting, and has a tying hole 21a bored in its base 21, and is integral with the eyeglass frame F so that this tying hole 21a is buried in the rim material resin. a corrosion-resistant strap arm 2 implanted in; a free end 2 of the strap arm 2;
2. An adjustable ringer pad in a synthetic resin eyeglass frame, characterized in that it includes a clinger pad 3 attached to the frame.

In addition, a connecting hole 21a through which the resin should flow and harden is bored at one end of a part used in such an adjustable ringer pad, that is, a narrow metal plate that can easily correct twisting. This allows the eyeglass frame F to be integrally planted on the rim frames 1, 1 with the point as the root portion 21, and
The other end is used as a free end 21 to which a clinger pad 3 can be attached, thereby realizing a band-type arm for supporting the pad.

Accordingly, in the present invention, all the materials used for conventionally known synthetic resin eyeglass frames can be adopted as the molding material for the eyeglass frame F.

Next, the material of the corrosion-resistant strap arm 2, which is a narrow metal plate that can easily correct twisting, does not rust or corrode due to sweat or grease, and is easily fatigued even after repeated twisting. It is required to select a metal with high toughness that does not cause However, the problem of corrosion resistance of metal materials can be addressed by surface treatments such as plating and painting. Therefore, metals that can satisfy such requirements for the strap arm 2 by themselves include stainless steel (for example, SUS305), nickel chromium alloy (for example,
Inconel), nickel-copper alloys (eg, Monel), and titanium alloys (eg, titanium-nickel shape memory alloys). Although a tie hole 21a is formed in one end (base portion 21) of the strap arm 2 made of such a metal material, the shape of the tie hole 21a is not necessarily an angular shape as shown in the illustrated example. They do not need to be holes, but may have any shape as long as they are penetrating holes into which the resin can flow in a chain shape and solidify, and a plurality of holes may be provided. Furthermore, in the case of the clasp arm 2 shown in FIG. 2, a tying hole 2 is provided at the portion that will become the free end 22 in order to strengthen the bonding force of the linger pad 3.
2a is drilled, but this connection hole 22a
The shape of the pad 3 is also not limited to the illustrated example; for example, it is possible to make a through hole with a decorative shape. is obtained.

As a method for integrally planting the above-mentioned banding cord 2 on the rim frames 1, 1 of the frame F, when the rim frame is molded by injection molding, the so-called insert method may be adopted; Since the resin flows into the hole 21a in a chain shape and solidifies, it never falls out. If injection molding is not used, make a hole in the rim frames 1 and 1 and apply a synthetic resin adhesive such as epoxy resin, acrylic resin, or urethane resin or synthetic rubber adhesive such as nitrile rubber or butyl rubber to the hole. The root part 21 of the strap arm 2 is filled with the agent.
If it is inserted and allowed to naturally dry or heat polymerize, it will be finished in the same state as when the insert method is applied.

The material of the linger pad 3 can be the same synthetic resin material as conventional linger pads. For example, if soft silicone resin is used, a linger pad with a good feel can be obtained. The clinger pad 3 is attached to the free end 22 of the strap arm 2. In this case, as shown in FIG. The distance between pad 1 and pad 2 can be set to a desired length. Incidentally, if a plurality of types of linger pads 3 are prepared and the wearer is allowed to select one and install it at an eyeglass store, it is possible to satisfy the taste buds.

Although the structure of the present invention is generally as described above, the present invention is by no means limited to the above-described embodiments, and various modifications can be made within the scope of the claims. It goes without saying that the shapes of the root portion 21 and free end portion 22 of the arm 2, as well as the shapes of the tying holes 21a and 22a formed therein, may be modified as appropriate in accordance with specific requirements in product design. be.

As is clear from the above explanation, in the synthetic resin eyeglass frame manufactured by applying the present invention, the linear arm 2' does not fall off from the base 21' like in the conventional product shown in FIG. 21'
It is necessary to ensure that the attachment of the part does not loosen and spin idle, and that it can be maintained firmly integrated with the rim frames 1, 1, and the direction angle of the pad 3 can be adjusted to match the wearer's nose bridge surface. When there is
The angle can be easily adjusted by holding the pad 3 and bending the strap arm 2 as desired. In this case, the band arm 2 has an excellent pad supporting capacity unlike the conventional linear arm using metal wire, and is less likely to cause metal fatigue, and since it is made of a corrosion-resistant metal, sweat and It can maintain its beautiful metallic beauty forever without deteriorating due to fat deposits.

As described above, according to the present invention, the numerous drawbacks that were considered inevitable in conventional synthetic resin eyeglass frames can be eliminated, and the quality and quality of synthetic resin eyeglass frames can be improved without complicating the structure in any way. It can be said that it greatly contributes to improving functionality.
