Description

[Detailed Description of the Invention] The present invention relates to eyeglasses that allow the user to easily attach and detach lenses.

In recent years, with the diversification of fashion, there has been a demand for alterations to eyeglasses such as sunglasses, but it is costly to change eyeglasses one by one in response to rapidly changing fashion trends in various fields.

This design was devised for the purpose of changing the lens color by easily replacing the lenses to match the current trends.To explain its configuration with reference to the drawings, Figure 1 shows the front view of glasses with removable lenses. 2 are rear perspective views of essential parts, and FIGS. 3 and 4 are cross-sectional views taken along lines A-A and B-B in FIG. 1.

In the drawings, 1 is the front frame of the glasses, 2 is the bridge, and 3 is the front frame of the glasses.
is a lens whose outer periphery is overlapped with the front surface of the front frame,
Reference numeral 4 includes several hooks attached from the top of the front frame to the left and right sides, each of which engages with the outer periphery of the lens.

Reference numeral 5 denotes an elastic support frame formed by bending an elastic material such as a metal wire or a synthetic resin rod into a chevron shape. A pad 8 is provided in the middle of both sides, and a front frame 1 and a lens 3 are provided at each lower end.
A hook 9 is attached to the outer periphery of the hook.

In the glasses of this invention, when the left and right pads 8 are pinched and pulled together, both the left and right sides 7 of the attachment frame 5 come close together, and the hook 9 escapes from the outer periphery of the front frame 1 and the lens 3.
Furthermore, if you move the pad 8 a little backwards while still holding it (to the position indicated by the dashed line It escapes from each hook 4 by pulling it in the direction of arrow Y).

When fitting the lens 3, first engage the top and side edges with the hook 4 so that the rear surface of the outer periphery overlaps the front surface of the front frame 1, pinch the left and right pads 8, and pull together the left and right sides 7 of the attachment frame 5. When the hook 9 is released after superimposing it on the back surface of the front frame 1, the hook 9 engages with the outer periphery of the front frame 1 and the lens 3, and there is a possibility that the engaging part may detach naturally due to the elasticity of the attachment frame 5. There is no.

As mentioned above, the glasses of this invention allow the user to put on and take off the lenses with a single touch without using any tools, so they can be used especially when the fashion changes frequently, such as sunglasses, or when the purpose of use has changed. It is convenient for replacement.

[Brief explanation of the drawing]

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A hook that engages with the outside of the lens is attached from the top edge of the front frame of spectacles on which lenses are superimposed on the front side, extending from the left and right sides to the outside of the lens, and below the bridge of the front frame. Claim No. 1 for Utility Model Registration consisting of overlapping chevron-shaped elastic support frames, the top of the support frames being pivoted to the bridge, and hooks that engage with the outside of the lens and pads attached to both left and right sides. Eyeglasses with removable lenses as described in section. (2) Eyeglasses with removable lenses as set forth in claim 1 of the utility model registration claim, in which metal wire is used as the elastic frame material. (3) Eyeglasses with removable lenses as set forth in claim 1 of the utility model registration, in which a synthetic resin rod is used as an elastic frame material.
