Although there are various types of spectacle frames for double mounting as described above, many of these require time and effort to install, and many are unstable after installation.

The present invention was devised for the purpose of eliminating the above-mentioned drawbacks in this type of eyeglass frame, and its configuration will be explained with reference to the drawings. Figure 1 is a front view of a double-mount eyeglass frame according to an embodiment of the present invention. , FIG. 2 is a sectional view of the main part.

In the drawings, reference numeral 1 denotes a front frame, and horizontal spring cylinders 2 are fixed to the upper left and right sides of the frame.

Reference numeral 3 denotes a reciprocating shaft housed in the spring cylinder, and a coil spring 4 is attached as a tension between one end of the shaft and the mouth of the spring cylinder 2, and the shaft head is pulled out of the cylinder and a clip 5 is attached to it. to hold.

There are other means of connection between the shaft head and the clip 5, such as fixing or screw fitting, but as shown in the figure, a universal joint 6 is used.
It is especially convenient to use .

In addition, a screw cap 7 or a push-in cap (not shown) as shown in the figure is attached to the opposite end of the spring tube 2 to the reciprocating shaft pull-out portion.
By attaching it, you can easily adjust and repair the cylinder mechanism.

The double-mounted eyeglass frame of this invention is used by fitting a lens for near vision into the front frame 1, superimposing it on the back of the glasses being worn when necessary, and inserting the clip 5 into the temple of the glasses being worn. Due to the action of the coil spring 4, it can be attached to various glasses of different sizes without loosening, it is easy to put on and take off, and there is no risk of shaking during use.
The appearance is extremely good as there are no hangers etc. exposed on the front of the glasses.
