Description

DETAILED DESCRIPTION OF THE INVENTION This invention improves Agaki without eliminating Gata-purple. This invention relates to a connection device between the eye and the temple in an eyeglass frame.

As shown in Figure 1, the glasses are made up of 11 glasses frames in which the glasses lenses are attached; It is made up of the vines 6 and 6, and is used as a connecting device between the vines 2 and 6 in Fig. 2.
Look at something like the one shown in Figure 3. That is, at one end of the vine 6.

and a connecting piece 51 provided with a screw hole 61A.

The connecting piece 62, in which the upper VC cylindrical groove 62A is recessed and the lower part has a circular hole 62B, is spaced one foot apart.
The connecting pieces 5t, 62 are arranged facing each other and are missing.
A 9 circular hole 21A is drilled in the dark, and the insertion piece 21 protruding from one end of the handle is inserted, and the tightening screw 22 is inserted into the circular hole 62B, 21A. The base of the housing is pressed into contact with the bottom of the cylindrical groove 62A, and is screwed into the screw hole 51A.

In this prior art, the handle and the temple 6 are made of metal.
Knots 61.62. This is because they are threadedly coupled via the insertion piece 21 and the tightening screw 22.

The insertion piece 21 of the tightening screw 22 rotates as the temple 3 opens and closes.
If the I front screw 22 repeatedly stops slightly due to pressure contact with the I front screw 22 and the screw hole, 1)
As the IA wears out and becomes loose, the tightening force of the tightening screw 22 decreases, resulting in looseness when opening and closing the crane 6, that is, a loss of holding power when the crane 6 is held still in the vertical position. It has a drawback of being 6.

This invention has been made with the aim of solving the drawbacks of the prior art, and the invention has been made to solve the above-mentioned drawbacks of the prior art. The cylinder t4 is recessed. Alternatively, a connecting piece in which a circular hole is bored is opposed to each other at a constant interval t, and is protruded from one end of the temple, and a tube of the same thickness and made of a material thicker than metal is connected to the circular hole and the cylindrical groove, respectively. The insertion piece t is press-fitted into the circular hole, has a circular hole approximately equal to the inner diameter of the tube, and is protruded from one end of the tube. The tube is press-fitted into the circular hole of the insertion piece.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 4 and FIG. 5 are diagrams showing an embodiment of the present invention.

゛First of all, to explain the structure, it is a 41'ri connecting piece, and the 4
A circular hole 41A is formed in the center of the connecting piece 41.

A tube 42 having an outer diameter slightly larger than the circular hole 41AKIi and the circular hole 41A is press-fitted.

Reference numeral 46 denotes a connecting piece, which is protruded above 11111 of the -V part of the temple 4 and facing the connecting piece 41 at a constant distance t. r446A is recessed.

Alternatively, instead of recessing the cylindrical surface 46A in the connecting piece 46, a circular hole as shown in the figure may be bored. The centers are on the same line, and a tube 44 made of the same material and having the same thickness as the tube 42 is press-fitted into the two cylinders r446A or a circular hole (not shown). The material for the tubes 42 and 44 is softer than metal, hard rubber, plastic, and special VCtit resin with good abrasion properties.

In addition, connecting pieces 41, 46. Circular hole 41A cylindrical groove 46
A or circular hole 11 (not shown) and tube 4
If 2.44 is press-fitted, the rod τ vine 4 will be placed inside one end of the vine 4.
cedar is formed in one row, a cylindrical scrap is recessed in the # body, or a circular hole is made, and a tube button is press-fitted into the circular hole across the cylindrical groove,
Then, by cutting out the middle part of the rod.

Anything is fine.

The connecting piece 41 may be placed above the connecting piece 41, and the connecting piece 46t may be turned over and placed at the lower side.

The insertion piece 1 is a bl-shaped insertion piece that protrudes from the inward opening ridge at one end of the tooth 5, and a circular hole 51A is bored in the center of the insertion piece 1.

The thickness of the insertion piece b1 is approximately equal to the separation distance between the connecting pieces 41.46, and the diameter of the circular hole 51A is equal to the inner diameter of the tube 42.44. be done.

6I-1' spring bin is made of metal, or stainless steel, and its outer diameter is larger than the inner diameter of the bottom tube 42, 44 and the diameter of the circular hole 51. Spring pin 61/'i, driven in, tube 429
The circular hole 51A and the tube 44vc are press-fitted.

By this driving and press-fitting, the tip of the spring pin 6 comes into pressure contact with the bottom surface of the cylinder g46A, or becomes flush with the top surface of the connecting piece 46, and the spring pin 6 is reduced in size to its nominal diameter.

Due to this spring tension, the connecting pieces 41, 46 and the insertion piece 1 are connected without the ssolling bottle 61d coming off.

Next, the action will be explained.

When the lever 5 is fixed and the temple 4 is opened and closed, the middle part of the spring pin 6 is inserted into the insertion piece 5 depending on the use.
1, the spring pin 6 does not rotate, but instead the tubes 42 and 44 move as the temple 4 opens and closes.
Rotate.

Due to this rotation, both ends of the spring bin 0 and the tubes 42 and 44 are rubbed, causing wear γ.

The wear occurs only on the tubes 42 and 44 made of a red material, and does not occur on the spring pins 6 made of hard t, -, ttJ.

Since plastic, especially polyacetal 1i111 which has good wear resistance, is used as the soft material, its premature wear weight Vi is extremely small.

Then, by numerous openings and closings of the temple 4, the tube 42.
When 44 is expanded, the inner diameter of tube 42.44 becomes 7/Ji.

As the size has increased, there are 1 non-pin and 6 stripes.

The spring tension spreads out to the side. Therefore, since the spring pin 6 is always pressed into the tube 42 and 44, there is no looseness between the two, and the stiffness is improved.

Due to progressive wear of tubes 42,44.

When the inner diameter of the tube 42, 44 is the same as the outer diameter of the tin ring bottle 6, at both ends of the spring pin 6,
Since the spring action is eliminated, the pressure contact between the spring pin 6 and the tubes 42, 44 is eliminated. However, in this invention, the amount of wear on the tubes 42 and 44 is extremely small.

Until such a state is reached, the mounting that causes the temple 4 to be rotated at least 10,000 times is bent, and there is a very small chance that rattling noise and stiffness will occur compared to conventional threaded connections.

In addition to the above description, the present invention has a connecting piece in which nine circular holes are formed and a cylindrical groove is recessed therein. Alternatively, a connecting piece with a circular hole bored therein is placed facing each other at a certain distance, and is cut out at one end of the temple υ, and seven tubes of the same diameter and made of a material softer than metal are connected to the circular hole and An injection port is provided in the cylinder 1 or the circular hole, and a circular hole approximately equal to the inner diameter of the tube is bored, and an insertion piece, which is missing in the tube, is of course inserted between the connecting pieces. death.

In addition, by press-fitting a metal spring pin into the circular hole of the tube and the insertion piece, the play between the head and the temple is eliminated, so that the effect can be obtained as soon as the tension at the time of opening and closing of the temple is eliminated.
