Description

[Detailed description of the invention] This invention relates to the improvement of six-fold glasses.The purpose of the invention is to make the glasses comfortable to wear by having the left and right temples grip the temporal region of the head with appropriate elasticity during use. To provide six-fold eyeglasses that can be easily folded by freely bending the temples during a folding operation, while giving a comfortable feel.

The eyeglass frame, in which the eyepiece sides of the left and right rims are folded together and the left and right temples can be folded into the gap between the folded rims, is conventionally known as the six-fold glasses type, and can be carried compactly. Since then, it has been widely used in reading glasses. However, since the center part of the temple is simply connected by a hinge, it is difficult to fold the left and right temples between the rims, so it is often used by elderly people. In the case of reading glasses, errors in the procedure often resulted in scratches on the lenses and damage to the hinges of the temples.

The present invention was devised in view of the above-mentioned difficulties in conventional six-fold glasses, and will be explained based on the illustrated embodiment: These are conventionally well-known six-fold glasses which are connected in a biaxial hinge manner, and in which the left and right temples 3 are hingedly connected 33 to a main bar 31 and a terminal bar 32, which are pivotally connected to a hinge bracket 4, so that they can be folded inward. , the main bar 3 in the temple 3
This invention provides six-fold eyeglasses that are easy to fold and are characterized in that the required range of the temples 3 is made up of coil springs 34, and that the temples 3 can be bent in any direction. In addition, numeral 5 in the figure is a substantially Ω-shaped nose pad made of elastic plastic such as silicone resin, and the rim 1 is formed by the bridge 2.
A biasing force for outward opening is applied to the biaxial hinge-like connection between and 1.

To explain the illustrated example in more detail, the left and right rims 1 on which the lens L is attached are of a so-called "crab-eye" type with a small vertical width. Plugs 11 are protruded from each of the left and right rims 1, and these plugs 11 are biaxially hinged by pivots 21, 21 of the bridge 2.

Next, the temple 3 is composed of a main bar 31 hingedly connected to the hinge bracket 4 and a terminal bar 32 having an ear hook part 32a. It is composed of a spring 34.

Although the six-fold glasses of the present invention are generally constructed as described above, the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the "Utility Model Registration Claims." Needless to say, for example, in the illustrated example, temple 3
Although the temple 3 is folded between the rims 1 and 1, it is also planned that the temple 3 will be wrapped around the outside of the rims 1 and 1.

As explained above, in the six-fold glasses of the present invention, the necessary range of the main bar 31 in the temple 3 is made up of the coil spring 34, so when the glasses are folded, the coil spring 34
The parts can be bent in any direction. Therefore, even an elderly person who is not good at close-up work or delicate work can easily fold the temple 3 without bringing it into contact with the lens L of the glasses or putting strain on the hinge part.

In addition, the coil spring 34 in the six-fold glasses of the present invention exerts favorable elasticity and clamps the temporal region of the head during use, so the person wearing the glasses can enjoy an extremely comfortable wearing feeling. I can do it.

As described above, the present invention not only simplifies the folding operation, which was conventionally considered a chore in six-fold eyeglasses, but also improves the feeling of wearing it. play.

Claims (1)

[Claims for Utility Model Registration] The right and left rims 1 on which the lens L is attached are connected by a bridge 2 in a biaxial hinge manner, and the left and right temples 3 are pivoted to a hinge bracket 4 by a basic bar 31. and a terminal bar 32 are hinged 33 so that they can be folded inwardly, and the necessary range of the main bar 31 in the temple 3 is configured with a coil spring 34, so that the temple 3 can be moved in any direction. Six-fold glasses that are easy to fold and are characterized by being bendable.
