Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adjustable ringer pad for synthetic resin eyeglass frames, and its purpose is to provide a ringer pad that can be freely adjusted in angle so as to properly fit the nose bridge of the wearer. To provide a synthetic resin eyeglass frame 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 clinger bud 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. .

Recently, a nose pad system called "Klingerbud" has become widely used for metal frame glasses. This nose pad method called Klinger Bud has a resin pad attached to the tip of an arm made of metal wire via a holder box, and the other end of the arm is welded to the left and right rim frames near the nose bridge surface. 1
It is extremely popular because it fits precisely 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 also been proposed. It's starting to look like this. However.

In this case, the undercut metal wire arm tip 21'' was heated and press-fitted into the resin of the rim frame 1'', thereby supporting the pad 3''. Not only does an unsightly crack occur at the point P where the 21° is press-fitted, but also 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 when wearing the arm. An inevitable problem was that the rod 31 began to spin idly around its tip 21, making it impossible to maintain the proper position of the rod 31.

The present invention was made in view of the above-mentioned difficulties in using Klinger Buds in synthetic resin eyeglass frames, although they were popular among eyeglass wearers. A special corrosion-resistant belt mold arm is used as the material for the arm that connects the clinger pad and the rim frame.
By drilling a connection hole at the base and burying the fitting in the resin material of the rim frame, we have eliminated the drawbacks of the conventional method. This book also allows you to adjust the distance between the pad and the rim so that the distance between the pad and the rim is the maximum distance.

Therefore, the configuration of the present invention will be explained based on an embodiment shown in the drawings: A glasses frame F molded from a synthetic resin; A corrosion-resistant clasp arm 2 is integrally implanted in the eyeglass frame F such that a wire connection hole 21a is formed in the rim material resin and the wire connection hole 21a is buried in the rim material resin;
1. An adjustable ringer pad for a synthetic resin eyeglass frame, characterized in that it includes a clinger band 3 attached to a free end 22 of the frame.

Also, parts used in such adjustable rings, ie.

A connection hole 21a for resin to flow in and harden is bored at one end of a narrow metal plate that can easily correct twisting, and the connection hole 21a is connected to the base 2.
1, it is possible to integrally install the eyeglass frame F on the rim frame 1, 1, and the other end is made into a free end 21 to which the rim frame 3 can be attached. This realizes a band-type arm for supporting bands.

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

Next, the material of the corrosion-resistant strap arm 2 is a narrow metal plate that can be easily corrected for twisting. It is required to select a metal with high toughness.

However, the problem of corrosion resistance of metal materials can be addressed by surface treatments such as plating and painting. Therefore, stainless steel (for example,
SUS 305), nickel-chromium alloy (for example.

Inconel), nickel-copper alloy (e.g. Monel), titanium alloy (e.g. titanium-nickel shape memory alloy), etc. One end (root part) of the strap arm 2 made of such metal material 21), a connection hole 21a is bored.

The shape of the connection hole 21a does not necessarily have to be a square hole as shown in the illustrated example, but may be any shape as long as it is a single through hole through which the resin can flow in a chain shape and solidify. A plurality of them may be provided.

Furthermore, in the strap arm 2 shown in FIG.
Free end 22 for strengthening the bonding force of the clinger pad 3
Although the wire connection hole 22a is bored in the region where the wire connection hole 22a is formed, the shape of the wire connection hole 22a is not limited to the illustrated example, and it is also possible to make it into a through hole with a decorative shape, for example. In case, Klinger Ballad 3 is made of transparent resin.
If you create one, you can get something interesting in terms of design.

As a method for integrally planting the strap arm 2 on the rim frame 1 of the frame F, a so-called insert method may be adopted when the rim frame is formed by injection molding.
In this case, the resin will flow into the connection hole 21a and solidify, so that it will never fall out. Also, if injection molding is not used.

Drill holes in the rim frames 1 and 1 and fill them with a synthetic resin adhesive such as epoxy resin, acrylic resin, or urethane resin, or a synthetic rubber adhesive such as nitrile rubber or butyl rubber, and then fill the holes at the base of the strap arm 2. If the section 21 is inserted and polymerized by natural drying or heating, a state similar to that obtained by applying the insert method will be obtained.

The material for the Klinger Bud 3 can be the same synthetic resin material as the conventional Klinger Bud. 1 For example, if a soft silicone resin is used, it will have a good feel.
You will get a band. This Klingerparad 3 is attached to the free end 22 of the strap arm 2, but in this case,
As shown in FIG. 3, the distance between the rim 1 and the pad 2 can be set to a desired length by appropriately adjusting the embedding depth of the free end portion 22 of the strap arm. In addition, Clinger Pad 3
If a plurality of ff [cheeks] are prepared and the wearer is allowed to select one and have them installed 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 changes can be made within the scope of the claims.
In particular, the shape of the base portion 21 and free end portion 22 of the strap arm 2, and the connection holes 21a and 22a drilled therein.
It goes without saying that the shape may be modified as appropriate in response to specific requirements in product design.

As is clear from the above description, there are synthetic resin eyeglass frames manufactured by applying the present invention.

As in the conventional product shown in Fig. 3, the linear arm 2' is at the base 2.
The pad 3 will never fall off from the 1" part or will not spin idle due to loose attachment at the base 21" part.
When it is necessary to adjust the same angle according to the bridge of the wearer's nose, the angle opening can be easily made by holding the pad 3 and bending the strap arm 2 by the desired amount. in this case,
The strap arm 2 is different from conventional linear arms made of metal wire, and has excellent pad support capacity, but also causes metal fatigue and wear, and is made of a corrosion-resistant metal, so it is resistant to sweat and wear.
It does not deteriorate due to alicycles and can maintain its beautiful metallic beauty for a long time.

As described above, according to the present invention, the numerous drawbacks that were considered inevitable in conventional synthetic resin eyeglass frames are completely eliminated, and the structure is not complicated in any way (1) Synthetic resin eyeglass frames It can be said that it greatly contributes to improving quality and functionality.
