2. If the length of the glasses is to be adjusted, a screwdriver must be used to loosen or tighten the screws (N, N´).

3. The -groove or + groove of the screw may be worn out due to frequent driving by the driver or the user's face may be damaged by the sliding of the driver when driving.

It is an object of the present invention to provide an adjustable pair of glasses that does not require any tools to adapt to the size of the user's face.

The main feature of the present invention lies in the installation of a pair of spectacles consisting of a half-sized anterior and a half-sized rear spectacles, and the rear spectacles are located at the rear end of the front spectacles and the front end of the rear spectacles. The front is provided by a longitudinal slot of the front and rear spectacles supported by a curved neck and a rounded neck and a curved neck which are provided and moved and the rounded projection is supported on one side of the front or rear spectacles. It is coupled to move back and forth with respect to the glasses legs.

The adjustable spectacles according to the present invention as shown in FIG. 2 are composed of two spectacles 4 and 5 coupled to the two lens frames 2 and 3 by screws N1 and N2. The two spectacles 4 and 5 have half-size front spectacles 40 or 50 and half-size rear spectacles 41 and 51 respectively joined together. The front spectacles 40 or 50 have longitudinal slots 400 or 500 at almost full length, and the rear spectacles have longitudinal slots 410 or 510.

The front spectacles 40 or 50 have a curved neck 401 or 501 connected to the round protrusion 402 or 502 at the rear end, and the curved neck 401 or 501 has a longitudinal slot 410 or 510. It has the same width as. The rear spectacles 41 or 51 also have curved necks 411 or 511 connected to rounded projections 412 or 512 at the front end.

Soft round rubbers 413 and 513 are provided at the rear end of the rear spectacles 41 or 51 to secure the spectacles to the wearer's face.

3, 4 and 5, when combined, the front eyeglasses 40 or 50 and the rear eyeglasses 41 or 51 may have rounded protrusions 402 or 502 that support the rear eyeglasses 41 or 51. It protrudes into the longitudinal slots 410 and 510 of and is supported on one side of the rear spectacles 41 or 51 and coupled together (FIG. 3 shows only the spectacles 5). In this position, the round protrusions 412 or 512 are slightly wider than the longitudinal slots 400 or 500, so the round protrusions 412 or 512 have not yet protruded through the longitudinal slots 400 or 500. It is located inside the glasses legs 4 and 5. Then open the longitudinal slot 400 or 500 of the anterior limb 40 or 50 slightly by hand, through which the round protrusion 412 or 512 passes as shown in FIG. 5) only shown].

2 and 6, when worn, the rear spectacles 41 and 51 are of appropriate length so that the length of the entire spectacles 4 and 5 fits the user's face as shown in FIGS.

Since the widths of the curved necks 401, 501, 411, and 511 are almost the same as the widths of the longitudinal slots 400, 500, 410, and 510, the curved necks can be pulled back and forth freely to stay in a constant position with moderate clamping force. Can be. In addition, the rounded projections 402, 502, 412, 521 are provided with the front and rear spectacles 40, 50, 41, to assist in securing the curved neck in a selected position upon adjustment of the length of the spectacles 4 and 5. 51) is supported on one side.

If it is necessary to shorten the spectacles 4 and 5, first, the rear spectacles 41 and 51 are pushed forward to the required position with respect to the front spectacles 40 and 50. When the curved necks 401 and 501 are pushed to reach the front ends of the longitudinal slots 410 and 510, the spectacles 4 and 5 become the shortest.

The present invention can have the following advantages.

1. The wearer himself can adjust the length of the glasses for comfortable wearing.

2. The length of the glasses legs can be easily adjusted without the need for any tools.
