Description

[Detailed explanation of the invention] The temples of the glasses can be the same as the glasses you currently use, but many people dislike glasses with unusual bezel shapes. In such a case, you will have to buy new eyeglasses with the shape you like.

The present invention aims to provide an eyeglass frame that allows users to wear eyeglasses in the desired shape by simply replacing the lens frame of the eyeglasses they are currently using without having to purchase new eyeglasses.

The present invention will be described with reference to the illustrated embodiment.

Rectangular shafts 2, 2 are fitted into both left and right ends of a rectangular thin cylinder 1, grooves 3, 3 are provided in the axial direction at both left and right ends of the cylinder 1, and a partition wall 4 is provided in the center of the cylinder 1. Protrusions 5, 5 are provided at the rear of each shaft 2, 2 to protrude into the grooves 3, 3 provided on the left and right sides of the cylinder 1, and the rear ends of the protrusions 5, 5 are connected to the partition wall 4. A locking cylinder body 7 with coil springs 6, 6 interposed between them so that the shafts 2, 2 protrude is installed across the left and right lens frames 8, 8, and the locking cylinder body 7 is placed in the center of the bridge 9. A rectangular receiver 10, 10 is provided so that it fits into the left and right shafts 2, 2 when they protrude, or the locking cylinder body 7 is crossed 9.
The cylinder body 10 is attached to the center part of the lock cylinder body 7 so that the left and right shafts 2, 2 of the locking cylinder body 7 fit into the left and right lens frames 8, 8.
The present invention relates to an eyeglass frame characterized by being provided with 10.

In addition, 11 is the armor 12,1 on both the left and right ends of the crossing 9.
A screw bearing piece provided on the inner surface of the lens frame 2 has a hole 15 into which the tips of tightening screws 14, 14 are fitted, the tips of which protrude from the left and right tips 13, 13 provided on the lens frame. 15 are provided.

According to the present invention, if the left and right protrusions 5, 5 provided on the locking cylinder body 7 are pinched with fingers and pulled inward against the coil spring, the left and right shafts 2, 2 are retracted, so that the shafts can be moved. When facing the rectangular receiving tubes 10, 10 provided on the bridge 9 or the left and right lens frames 8, 8, and loosening the pull of the protrusions 5, 5, the shafts 2, 2 will fit into the receiving tubes 10, 10,
The lens frame and bridge are integrated. In particular, since both the cylinder body 10 and the shaft 2 that fits therein are square, they do not rotate, and the bridge and lens frame can be securely attached.

Further, by pulling the left and right projections 5, 5 of the locking cylinder 7, the shafts 2, 2 and the square cylinders 10, 10 are disengaged, so that the lens frame can be easily replaced. Therefore, if you have several types of lens frames, you can wear glasses with different eye shapes.

Furthermore, as mentioned above, the receiving piece 11 is provided on the inner surface of the armor,
The tip of the screw 14 for tightening the lens frame is the receiving piece 11.
In the case where the shaft 2 of the locking cylinder and the cylinder 10 for the bearing are fitted into the hole 15, the locking cylinder shaft 2 and the bearing cylinder 10 may be circular instead of square. This is because the lens frame and bridge are attached to the locking barrel 7 and the armor 12 at two locations, above and below, so they can be securely attached without rotating relative to each other.
