Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to rimless glasses.

In rimless spectacles, a temple is attached to the outer end of the lens and a bridge is attached to the inner end. Eye plate-like lens stoppers extending from a member called a nail by those skilled in the art are attached to the lens by tightening with a tightening screw and a nut on each of the temple side and the bridge side. The claws on the temple side are connected to the armor, and the claws on the bridge side are connected to the bridge. The tightening screw penetrates the lens stop and the lens screw hole. The lens has a screw hole slightly inward of the position where it aligns with the screw hole of the lens stop, and as a result of eyeglass assembly, the nail is strongly pressed against the side surface of the lens, forming a so-called "hugging" for the lens. .

The rimless glasses are lighter than the rimmed glasses, and the appearance of the spectacle wearer is close to that of a bare face (hereinafter, this feeling is referred to as a bare face sensation. The appearance characteristics given to humans are called face orientation.)

[0004]

[Prior art]

 However, conventional rimless spectacles do not have sufficient level of lightness and slimness of the entire frame, and they do not give a fitting feeling that the entire frame is unnatural, and it is a purposeful purpose to prevent the lens from wobbling and to prevent rotation. To achieve below. The details are as follows.

Traditionally, the pawl is shaped to match the arc of the lens side it faces. A leaf spring is inserted between the lens and the claw to prevent the lens from wobbling and to prevent it from rotating. However, in this specification, although the nail is lightly pressed against the side surface of the lens, in order to achieve the desired lens wobbling prevention and rotation prevention, as is known to those skilled in the art, the dimension of the nail along the lens side surface arc is known. Must be relatively large. With such large nails, the temples and bridges must be made thicker from a practical point of view such as the strength balance of the material, and lightness, slimness of the entire frame, real face feeling, and face orientation are negative. Lean on.

[0006] Thus, among these points, the level of lightness and slimming cannot be made extremely high, and furthermore, the frame as a whole does not have an unnatural fit. In fact, it is widely known that the high level of these points is still lacking. Moreover, the prevention of wobbling of the lens and the rotation stop cannot be achieved under the proper purpose.

[0007] On the other hand, the temple needs to have a curved shape that is convex toward the outside of the eyeglasses to fit the face (this state is referred to as "crease" by many persons skilled in the art), and in the past, it has been necessary for the eye to do so. After the mirror is assembled, the temples are manually bent and "wrinkled", which does not always guarantee a good fit.

[0008]

[Problems to be solved by the device]

 The object of the present invention is to make the rimless spectacles extremely light and have a very slim frame so that the face feeling and the face orientation are extremely improved, and at the same time the whole frame has a natural fit. The more suitable "temple" of the temples is to improve the fit to the face, and to prevent the lens from wobbling and to prevent the lens from turning properly.

[0009]

[Means for Solving the Problems]

 In the rimless spectacles according to the present invention, the temples and the bridge side claws and the eye plate-like lens stoppers extending from the claws are formed by casting or bending the material, and the claws are formed on the claw surface. It is shaped like a curve slightly curved from the lens side arc of the part to be curved in the direction along the side arc, and the temples and bridges are round wire made of superelastic material such as cobalt alloy. It is characterized by being curved in a convex shape.

In the present invention, the claw and the eye plate-like lens stop portion extending from the claw are formed by casting or bending from the material so that the positioning of the claw with respect to the lens stop portion and a desired claw shape are performed. To get it, do so.

[0011]

【Example】

 Embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 is a claw on the temple 2 side, 3 is a claw on the bridge 4 side, and claws 1 and 3 and an eye plate-like lens stop portion extending from the claw are provided. 6 and 6 are formed by casting or bending from a material. Further, the claws 1 and 3 are curved arcs that are slightly smaller than the lens side surface arcs of the portions that the claws face, and the entire or inner surface is curved in the direction along the side surface arcs. The claw 1 is connected to the armor 5 and the claw 3 is connected to the bridge 4. The claws 1 and 3 are fastened to the lens L with screws 7 and nuts 8. 7'is a screw head, and 9 is a hole into which the screw 7 is inserted.

The temple 2 and the bridge 4 are made of a super elastic material such as a cobalt alloy and have a round wire shape, and the temple is curved in a convex shape to the outside of the eyeglasses so as to fit the face. ing.

Although the temples 2 and the claws 1 and 3 on the bridge 4 side are strongly pressed to the lens L side in the assembled state of the eyeglasses in the same manner as in the related art, in this case, the claws 1 and 3 are shown above. Due to this curved shape, the claws 1 and 3 are pushed into the lens L side by this pressure so as to "hold" the lens and bring about a very good "hugging". For this reason, the claws 1 and 3 of the present invention have a small dimension of about 3 mm in the direction along the lens side surface arc (corresponding to about 1/3 of the conventional general dimension) and prevent the wobbling of the required lens L. And play a detent. In addition, it is not necessary to insert a leaf spring between the lens and the claw, so the lens can be easily restrained.

When the claws 1 and 3 are small in this way, the temple 2 and the bridge 4 can be thinned without losing the balance in strength with the claws. In addition to this, since the temple 2 and the bridge 4 are round wire type, they can be further slimmed down. When the strengths are the same, among the wire rods of various cross-sections made of the same material, the round wire has the shortest perimeter of the cross-section and is thin, which means that the round wire type contributes to slimming of temples and bridges. Means

Thus, according to the present invention, the frame can be made extremely slim. In fact, as a result of trial production, it was confirmed that the thinnest portion can be made to have a thickness of about 0.6 to 0.7 mm. This is worthy of being ultra-fine in view of the fact that the conventional frame is generally thin and is approximately 1.4 mm. This ultra-slim design will greatly improve the feeling of face and the orientation of the face.

Furthermore, this super slim design, combined with the shape of the round wire of the temples 2 and bridges 4, gives a natural fit feeling that the whole frame is not unnatural.

Since the temple 2 and the bridge 4 are made of a superelastic material such as a cobalt alloy, a superfine round wire type frame having elasticity with a good overall balance can be obtained.

The temple 2 is made of such a superelastic wire material in the above-mentioned curved shape by a combination of swaging and press working, so that the temple 2 has a good "wrinkle" under unloading, that is, under no external force. Can be held.

Since the temple 2 is made of a super elastic material, its fit to the face due to “wrinkles” is extremely good, and when the glasses are put on the face, both temples are opened and widened considerably. However, due to the good balance of elasticity of the temple 2 and the bridge 4, it is possible to avoid applying an unreasonable force to the lens stoppers 6 and 6 and the lens L itself, and at the same time, the good fitting property shown above can be obtained.

[0021]

[Effect of device]

 As is clear from the above description, the present invention is a rimless spectacle that is light and has an extremely slim frame to improve the feeling of face and the orientation of the face to the utmost, and the frame is not unnatural and natural. It provides a good fit, and the better wrinkle of the temples improves the fit to the face, and it also has the effect of preventing the lens from wobbling and stopping rotation properly.
