Description

[Detailed Description of the Invention] The present invention relates to a nose pad up-and-down device for a multifocal eyeglass frame, which allows a user to move the eyeglass lens up and down with a simple operation and at the same time constantly obtain a comfortable wearing feeling.

Up to now, for example, by moving the support rod 3 up and down, the height of the nose piece 4 attached to the tip of the support rod 3 has been changed, and by moving the eyeglass frame up and down, it has been possible to change the distance lens of a bifocal lens. A variety of devices have been developed that allow different lenses for near vision to be used, but these devices not only have complicated mechanisms, but are also troublesome to operate.

In addition, the angle of the nose piece that rotates with the rotation of the support rod 3 changes significantly from before rotation, making it impossible to contact the side of the nose at the necessary angle, making it impractical and difficult to wear. Since it was not possible to obtain the desired effect, it has not been put into practical use until now.

The present invention allows the glasses frame to be adjusted up and down with a simple operation, and also compensates for changes in the contact angle of the nose piece, which rotates at the same time as the support rod rotates, on the side of the nose, and allows the frame body 1 to be moved up and down. When rotating the support rod by pushing up or down, the nose piece is shaped so that force is applied from the direction necessary to rotate the support rod, and the nose piece is shaped so that you do not feel any pain when pressed against it. The object of the present invention is to provide a nose pad up/down device for an eyeglass frame, which is mainly suitable for bifocal eyeglasses.

In order to satisfy the above object, the present invention is constructed as follows.

That is, in the present invention, a nose piece 4 having two upper and lower sloped surfaces 4a and 4b is attached to the tip of a support rod 3 which is pivotably mounted in the vicinity of the central connecting piece 2 of the frame body 1 so as to be able to rotate up and down. Glasses frame body 1
A bearing piece 6 at the tip of the piece 5 that comes into close contact with the central connecting piece 2 of
Insert the pivot ring 7 of the support rod 3 into the pins 8 and 6b.
A protrusion 90 that is pivotally supported by and protrudes around the pivot ring 70.
This is a nose pad up/down device for a multifocal eyeglass frame, characterized in that stoppers 10a and 10b are provided in steps on the bearing ring part 10 of the piece 5, with both ends 9a+9b touching and stopping the support rod 3 at a required vertical angle. .

As shown in FIGS. 1 to 5, the nose piece 4 is made of a wedge-shaped piece with vertically inclined surfaces 4a and 4b, which also allows the nose piece 4 to move when the frame 1 is moved up and down. When applying it to the forehead,
It also has the effect of making you feel no pain.

Also, what is shown in FIG. 6 is an annular spring 11. A washer 12 having elasticity is incorporated to prevent wear and loosening and to ensure smooth rotation, but the purpose can be achieved even if only one of them is incorporated.

Furthermore, the nose piece can have various shapes as shown in Figure 7.
All of these can be applied to the present invention.

That is, FIG. 7A is a reference diagram showing the twisting of the nose piece 4 having two sides.

In the following examples of shapes B, C, D, and E, the surfaces of the sloped surfaces 4a and 4b of the nose piece 4 are bent back and forth by approximately 30 to 90 degrees, and at the same time are twisted outward by approximately 300 degrees to further improve the adhesion to the sides of the nose. .

In B, the frequently used surface 4b is made larger, and the other surface 4a is made larger.
C is formed to be slightly smaller, C is formed with surfaces 4a and 4b of the same size, and D is nose piece 4 where surfaces 4a and 4b are separately provided by forked legs 13 and the angle can be finely adjusted. Form.

E shows a hemispherical nose piece 40 with inclined surfaces 4a and 4b provided on its surface, respectively.

In FIG. 8, 1 indicates farsightedness and 1 indicates nearsightedness.

Since the present invention has the above-mentioned configuration, in order to move the frame 1 upward, it is necessary to move from the far viewing state 1 (the state in which the nose piece 4 is raised) shown in FIGS. As shown in Figure A', press the inclined surface 4a of the nose piece 4 between the eyebrows (frontal area), rotate it, and lower it to the original side of the nose. In this state, the frame body 1 is fixed to the nose by the inclined surface 4a, and the frame body 1 is lifted up.

Conversely, when lowering the frame 1, press the nose pad piece 4 downward against the nose surface as shown in Figures 8 and 9 with the raised opening of the frame 1 as shown in Figure 9. Rotates upward and slopes 4b
is fixed to the nose, and the frame 1 returns to its original slightly lowered state, ie, A in FIGS. 8 and 9.

In any of the above usage conditions, the position of the nose piece 4 is determined by the both ends 9a, 9b and the stoppers 10a, 10b, and the nose piece 4 is reliably stopped.

In short, in the present invention, the frame body 1 is moved up and down by the distance that the nose piece 4 rotates up and down, and the angle change of the nose piece 40 due to the rotation is controlled by using the upper and lower two inclined surfaces 4a and 4b of the nose piece 4. It is compensated for by having a torsion of about 300 degrees, making it quick and easy to adjust the vertical movement.Moreover, since it is reliably stopped by both ends 9a + 9b and stoppers 10a and 10b in the vertical movement state, it does not move unexpectedly. Without,
Therefore, it provides a comfortable wearing feeling, and is therefore extremely useful as a nose pad up/down mechanism for bifocal eyeglasses.

That is, by simply moving the frame 1 up and down, the frame 1 and the nose piece 4 are excited, and the lens C can be adjusted to a desired focal position, allowing the user to use the lens C with peace of mind.
