Abstract

A pair of collapsible eyeglasses comprising two lens frames (20, 20') connected with a hinge (21) between them so as to be collapsible on each other, two arms (22, 22') of resilient material hingedly connected to the outer side of each lens frame and having almost the same length as that of each lens frame and carrying a silicone rubber pad (221, 221'). <IMAGE>

Description

Title: Collapsible Eyeglasses DESCRIPTION This invention concerns collapsible eyeglasses.

A pair of conventional eyeglasses, as shown in Figure 1 of the accompanying drawings, comprises a lens frame 10, two hinges 11, 11' at both outer sides of the lens frame, two nose pads 100, 100' at the inner sides of the lens frame, two arms 12, 12' united with the two hinges 11, 11', and two end pieces 120, 120' connected with the arms 12, 12'.

In use, the end pieces 120, 120' are laid on ears and the nose pads 100, 100' on a nose of a wearer, and in putting away, the two arms 12, 12' are folded on the back of the lens frame 10.

This type of eyeglass is considered to have the following drawbacks.

1. It is liable to slide off, not so convenient for wearing.

2. It takes rather a large dimension when put away.

In view of the disadvantages of conventional eyeglasses, an object of this invention is to provide collapsible eyeglasses, which are convenient in wearing, not liable to fall off, and collapsible preferably for putting away in a hard case of a comparatively small dimension.

According to the invention collapsible eyeglasses comprising; two lens frames hingedly connected so as to make them collapsible on each other; two side arms hingedly connected at the outer side of each lens frame, each arm being collapsible to the back of the lens frame, each arm having a laterally rounded free end; and said arms being of resilient material having almost the same length as that of each lens frame and each round end thereof bearing an adherent pad so that the eyeglasses can be worn stabilized by resilient pinching action of the arms and adhesiveness of the pads on the round ends of the arms.

Preferably the eyeglasses of the invention further comprise two nose pads separately fixed at the inner side of each lens frame and each having an adherent pad thereon.

The adherent pads are preferably of silicone rubber.

In wearing eyeglasses of the invention, the two nose pads are placed on both sloped sides of the nose of a wearer and the two arms are placed pinching both sides of a forehead. As the nose pads carry adherent pads, say of silicone rubber, and the free ends of the two arms also carry adherent, preferably silicone rubber, pads to touch with the skin, the eyeglasses can be prevented from sliding off. In addition, the two arms have a pinching elasticity due to the resilient material of which they are made so that they can hardly fall off both sides of the forehead of a wearer.

In storing away, this pair of eyeglasses can be collapsed to a smaller dimension than a conventional one, by collapsing the arms inwards on the lens frame nearer to them by means of the two hinges and then the lens frames on each other by means of the hinge between them. Thus, the collapsed pair of the eyeglasses can be placed in a hard case.

This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a pair of conventional eyeglasses; Figure 2 is a perspective view of the collapsible eyeglasses in accordance with the present invention; Figure 3 is a perspective view of the collapsible eyeglasses in the present invention worn on; and Figure 4 is a perspective view of the collapsible eyeglasses in the present invention collapsed.

Referring to Figures 2 to 4 of the accompanying drawings, collapsible eyeglasses of the present invention comprise two lens frames 20, 20', two nose pads 200, 200' at the inner side of the two lens frames 20, 20', two silicone rubber pads 201, 201' adhered on the nose pads 200, 200', two hinges 202, 202' at the outer side of two lens frames 20, 20', united with an end of each of two arms 22, 22', a hinge 21 between the two lens frames 20, 20', two arms 22, 22' made of resilient material and having one end joined with the hinges 202, 202' and the other end formed as laterally rounded ends 220, 220' carrying silicone rubber pads 221, 221' of the same size as the round ends 220, 220' and almost the same length as the lens frames 20, 20'.

In using, the nose pads 200, 200' are placed on the two sloped sides of the nose of a wearer, the two arms are placed pinching the two sides of a forehead and the two rounded ends 220, 220' with silicone rubber pads 221, 221' sticking on the skin of the two sides of the forehead so as to keep this pair of eyeglasses from falling off.

In putting away, the two arms 22, 22' are separately collapsed on the back of each lens frame 20, 20' by means of the hinges 202, 202', the lens frames 20, 20' are collapsed on each other by means of the hinge 21, and finally the collapsed eyeglasses can be contained in a hard case 3 as shown in Figure 4.

Claims

1. A pair of collapsible eyeglasses comprising; two lens frames hingedly connected so as to make them collapsible on each other; two side arms hingedly connected at the outer side of each lens frame, each arm being collapsible to the back of the lens frame, each arm having a laterally rounded free end; and said arms being of resilient material having almost the same length as that of each lens frame and each round end thereof bearing an adherent pad so that the eyeglasses can be worn stabilized by resilient pinching action of the arms and adhesiveness of the pads on the round ends of the arms.

2. Collapsible eyeglasses as claimed in claim 1, further comprising two nose pads separately fixed at the inner side of each lens frame and each having an adherent pad thereon.

3. Collapsible eyeglasses as claimed in claim 1 or 2, wherein the adherent pads are of silicone rubber.

4. Collapsible eyeglasses as claimed in claim 1, 2 or 3, wherein the collapsible eyeglasses are contained in a hard case so as to enable them convenient for carrying and to prevent them from being broken by compressing.

5. Collapsible eyeglasses substantially as hereinbefore described with reference to and as illustrated in figures 2, 3 and 4 of the accompanying drawings.
