Description

DETAILED DESCRIPTION OF THE INVENTION Glasses for general Japanese people are usually fitted with temples inclined downward at about 8 degrees with respect to the axis of the lenses. Also, glasses for people with high noses, such as foreigners, are fitted with the temples tilted downward at an angle of 12 to 18 degrees with respect to the axis of the lenses.

Therefore, in order for people with high noses, such as foreigners, to be able to wear glasses intended for the general public, the temples must be tilted downward by 12 to 18 degrees with respect to the axis of the lenses.

In addition, not only people with high noses but also people with large noses must change the downward angle of the temple with respect to the axis of the lens, that is, the angle of elevation and elevation of the lens, in order to be able to read letters clearly. However, if you can change the angle of elevation so that characters can be read clearly, you can easily find the most appropriate angle of elevation if you can change the angle of elevation while wearing your glasses.

To enable such operations, the present invention has a mechanism that allows the angle of elevation and elevation of the lenses to be changed with one hand while wearing the glasses.

The present invention attaches a hinge piece 2 to the end of the temple 1,
The mounting portion of the other hinge piece 3 that engages with this is formed long to form a base 4 for attaching the lens frame elevating body, and the base 6 of the lens frame elevating body, which has a chisel 5 on the tip side, is attached to the base 4. It is formed long so as to be joined to the base 4, and screw insertion holes 7 are provided at the front and back of the joined base 4 and the base 6.
For example, the rear screw insertion hole 8 is provided with a circular hole 9 for screw insertion in the base 6, and the front screw insertion hole 7 is provided with a circular hole 9 for screw insertion. An oval hole 10 with a long diameter is provided in the vertical direction in the base 4, a plurality of grooves 11 are provided side by side at the tip of the base 4, and a groove 11 in the tip of the base 4 is provided in the tip of the base 6. A hole 12 for inserting a presser is provided with a threaded groove at the entrance so as to communicate with each other, and a ball 13 and a coil spring 14 are fitted into this hole, and a presser cover 15 is screwed into the threaded groove of the hole 12. It relates to a lens frame elevating mechanism for eyeglasses, which is formed by pushing a ball 13 into it, and a hard plate material 16 such as a leaf spring may be inserted into the protrusion of the groove 11 at the tip of the base 4 in order to prevent the protrusion of the groove from being worn out. be.

In addition, 18 is the front screw, 19 is the rear screw, 2
0 is a synthetic resin pipe for screw removal prevention.

In the present invention, the base 4 for attaching the lens frame elevating body
Among the front and rear screw insertion holes 7 and 8 that connect the base 6 of the lens frame elevating body, one screw insertion hole 10 provided in the base 4 of the front hole 7 is elongated in the vertical direction. Since the hole is an elliptical shaft, if the screw is tightened loosely, the base 6 of the lens frame elevating body will fit into the rear screw insertion hole 8 within the long axis of the ellipse. It rotates up and down around the axis of the screw 19 screwed in.

Due to this rotation, the lens frame attached to the tip 5 on the distal end side of the base 6 of the lens frame elevating body is elevated. In addition, a ball 13 is pressed by a coil spring 14 to the protrusion of a plurality of triangular grooves provided at the tip of the base 4, and the base 6 of the lens frame elevating body cannot be rotated unless it is rotated by hand. do not. That is, the elevation angle of the lens frame is kept constant.

Therefore, adjust the screwing of the screw cap 15 so that the ball presses the protrusion of the groove at the tip of the base 4 with an appropriate force, and then screw it into the base 4 while wearing glasses. By rotating the base body 6 around the axis of the rear screw 19, the angle of elevation and elevation of the lens frame can be changed at any time.

If you want to keep the elevation angle constant, rotate the base 6 of the lens frame elevation body in the vertical direction as described above, and when the desired elevation angle is obtained, firmly screw in the screw cap 15 to release the ball. 13 is strongly pressed against the protrusion of the groove 11 by a coil spring 14, and the base 6 cannot be rotated, so that the angle of elevation is kept constant. Furthermore, if the screw 18 screwed into the screw insertion hole 7 in the front part, which has an oval hole, is firmly screwed in, the base 4 and the base 6 will come into close contact with each other, and the base 6 cannot be rotated, making the angle of elevation even more secure. can be kept constant.

In addition, if a hard plate 16 such as a leaf spring is inserted into the protrusion of the triangular groove, it will not wear out even when the base 6 is rotated, and the ball pushed by the coil spring will move through the hard plate. Pressed against the end surface, the base 6
The angle of elevation of the lens frame is also kept constant.

In addition, in the case of glasses in which the eyebrows 21 are made of celluloid, synthetic resin, etc., a ball or coil spring is inserted into the presser fitting hole provided at the tip of the base 6, and a protrusion 17 with a flange is provided at the tip of the screw hole at the entrance. By screwing in the rear cover 15' to press the ball 13 and coil spring 14, and embedding the flanged protrusion 17 provided on the rear cover 15' into the celluloid or synthetic resin of the eyebrow, this lens frame elevating mechanism can be adjusted to the eyebrow. It can also be attached to eyeglass frames.
