Description

[Detailed description of the invention] The upper edges of the left and right lens frames are formed integrally, and the left and right lens frames are formed continuously on each edge of these frames, and the upper edges of the left and right inner edges are connected with a bridge. A spectacle frame is conventionally known in which the upper end of a bridge support piece is pivotally attached to the center of the upper edge of the frame, and the bridge support piece is provided with a stepped portion for lifting and supporting the bridge.

However, when fitting the lens into the frame, it is difficult to orient the bridge attached to the inner upper part of the frame to the groove on the upper edge. It is not easy.

The present invention aims to provide eyeglasses that allow the user to easily replace the lenses.

In the present invention, the upper edges of the left and right lens frames are integrally formed, and the left and right lens frames 1, 1 are formed continuously on each end, and the upper edges of the left and right inner edges 2, 2 are connected by a bridge 3. A lower cylindrical body 5 with a shaft 4 protruding from the upper surface of the bridge 3 is provided vertically, and this cylindrical body 5
An upper cylindrical body 6 is provided at the center lower surface of the upper edge 7 of the lens frame so that the shaft 4 can be inserted thereinto, and the upper end of the coil spring 8 is fixedly provided within the upper cylindrical body 6.
A U-shaped bridge support piece is formed into a long piece to receive the upper end of the shaft 4 provided on the lower cylinder 5 inserted into the upper cylinder 6, leaving a gap between the upper and lower cylinders 6 and 5. 9 to the bridge 3, the lower cylinder 5 and the upper cylinder 6
Fit the bridge support piece 9 across the triple body.
The tip of the long piece 10 is rotatably attached to the center of the upper edge 7 of the lens frame, so that when the end surfaces of the upper cylinder 6 and the lower cylinder 5 come into contact, the state of contact can be maintained.
The present invention relates to an eyeglass frame characterized in that a bridge pushing-up protrusion 11 is provided on the inner surface of a bottom piece 10 of a letter-shaped bridge support piece 9 so as to leave room for the bridge 3 to fit therein and to be biased to the side. Reference numeral 12 denotes a shaft for rotatably attaching the long piece of the bridge support piece 9 provided on the upper edge 7 of the lens frame.

According to the present invention, the upper part of the shaft 4 provided on the lower cylinder body 5 is inserted into the upper cylinder body 6, so when fitting the lens into the frame, the lens fitted on the left and right edges and the lower edge of the frame is inserted into the upper cylinder body 6. The upper edge faces the groove on the upper edge of the frame, so
The lens fits onto the upper edge of the frame simply by bringing the upper cylinder 6 and the lower cylinder 5 into close contact with each other against the pressing force of the coil spring 8. The lens can be reliably attached to the eyeglass frame simply by rotating the letter-shaped bridge support piece 9 and pushing up the bridge 3 with the protrusion 11 provided on the bottom piece 10.

In this way, the upper edge of the lens fitted to the left, right and lower edges of the lens frame always faces the groove on the upper edge of the lens frame, so the user can easily fit the lens himself.

Also, when the bridge support piece 9 is rotated to remove the protrusion 11 from the bridge 3, the coil spring 8 provided on the upper cylinder 6 pushes down the shaft 4 provided on the lower cylinder 5, and the upper and lower cylinders are separated. A gap is created between 6 and 5, and the lens frame widens, allowing the lens to be easily taken out.

Since the lenses can be easily replaced in this way, there is an advantage that if the user has spare lenses of various colors, he or she can easily replace them with lenses of the desired color and have fun. Further, since the upper cylinder 6, the lower cylinder 5, and the spring 8 are hidden by the U-shaped bridge support piece 9, there is an advantage that the appearance is not impaired.

Claims (1)

[Scope of utility model registration request] The upper edges of the left and right lens frames are integrally formed, and the left and right lens frames 1, 1 are continuously formed on each end of the lens frames, and the upper edges of the left and right inner edges 2, 2 are connected by a bridge 3. A lower cylinder 5 with a protruding shaft 4 is installed on the upper surface of the bridge 3, and the upper cylinder 6 is placed at the center of the upper edge 7 of the lens frame so that the shaft 4 can be inserted opposite to this cylinder 5. The upper end of the coil spring 8 is fixedly provided in the upper cylinder 6, and the upper end of the shaft 4 provided in the lower cylinder 5 inserted into the upper cylinder 6 is received by the coil spring 8. A U-shaped bridge support piece 9 with a gap formed between the upper and lower cylindrical bodies 6 and 5 and one piece long.
is fitted across the triple body of the bridge 3, the lower cylinder 5 and the upper cylinder 6, and the tip of the long piece 10 of the bridge support piece 9 is rotatably attached to the center of the upper edge 7 of the lens frame, and the upper cylinder When the end surfaces of the body 6 and the lower cylindrical body 5 come into contact, the bottom piece 10 of the U-shaped bridge support piece 9 is biased to the side leaving room for the bridge 3 to fit into the inner surface of the bottom piece 10 so that the contact state can be maintained. This eyeglass frame is provided with a bridge-pushing protrusion 11 and allows easy fitting and unfitting of lenses.
