“Attachment structure of nose pad in glasses frame” related to Utility Model Registration No. 3115064

In this way, when wearing glasses, nose pads that come into contact with both sides of the nose are used to hold the front part in a predetermined position. However, conventional nose pads have a limited range of motion and often cannot perfectly fit the shape of the nose.
Conventional nose pads are attached to the tips of the legs, and although their orientation can be adjusted slightly, there are restrictions and they cannot perfectly fit the sides of the nose. For this reason, at retail stores that sell glasses, store staff bend the legs to adjust the glasses to fit the buyer's nose.
In other words, the legs are held in place with a tool to bend them appropriately, but adjusting the bending of the legs is not easy for inexperienced staff, and the base of the legs that are brazed may come off due to the stress exerted during bending. Problems also arise.
The problem that the present invention aims to solve is to develop a nose pad that has a wide range of motion and can fit perfectly without having to bend or adjust the legs, regardless of the shape of the nose. Provide mounting structure.

In the mounting structure of the nose pad according to the present invention, the base of the leg is brazed to the rim, the curved tip of the leg is provided with a mounting portion, and the protrusion protruding from the back of the nose pad is fitted into the mounting portion. , is fixed with a screw provided on the mounting part.
Here, a hole passes through the upper surface of the mounting portion, and the leg fits into this hole. A plate is fixed to the tip of the leg by brazing or the like, and the mounting portion is pivoted so as to be able to swing within a predetermined range around the leg.

Although the specific means for regulating the swing angle of the mounting portion is not limited, it can be regulated by the side surface of the mounting portion coming into contact with the corner of the plate. A screw hole is provided in the side surface of the attachment part, and the screw inserted into the screw hole is fitted into the hole provided in the protrusion, thereby attaching the nose pad to the attachment part. Therefore, the nose pad can swing within a predetermined range around the screw.
The swing angle of the nose pad that swings around the screw depends on the size of the gap formed between the protrusion and the plate, and can swing within that range.

The nose pad of the present invention can swing within a predetermined range.
In other words, the nose pad swings within a predetermined range around the legs, and swings within a predetermined range around the screws that are perpendicular to the legs, so the shape of the nose changes. Even if it is, it can fit on both sides of the nose. No matter how high or low your nose is, it will fit correctly, the front part will be stably supported without shifting, and there will be no need to bend or adjust the legs like in the past, so even an inexperienced salesperson can easily fit the glasses. can be sold.

Mounting part that is pivoted on the leg. A specific example of a plate formed at the tip of a leg. When the nose pad is attached to the mounting part. A specific example showing a common glasses frame. Conventional mounting structure for attaching the nose pad to the front part.

The support structure of the nose pad according to the present invention is configured so that the front part of the glasses can be stabilized at a predetermined position. Therefore, there are no limitations on the form of the eyeglass frame, including eyeglass frames with a full rim into which the lenses fit, nylon frames that hold the lower side of the lenses with water string, or both lenses that are directly screwed together using a connecting member. There are also cases of rimless glasses with the endpieces directly screwed onto the outside.

The front part that includes the lenses has a nose pad, and the nose pad can fit on both sides of the nose no matter what shape the nose is when wearing glasses. It can swing and change direction within a predetermined range.
The nose pad is made of resin, sometimes soft silicone resin, and feels good on the skin. Of course, the material is not limited.
