Description

[Detailed description of the invention] [Industrial application field] The invention provides glasses that are highly flexible and easy to fit on the face, the eye wires are almost invisible from the outside, and the lenses are firmly held. It's about frames.

[Conventional technology]

A so-called frameless frame, in which the frame is not visible from the outside, has been proposed as a conventional eyeglass frame. For frames where the nose pad or temples are not screwed directly to the lens, a metal or resin frame is placed over the top of the lens to obtain the desired strength, and the temple or nose pad is attached to this frame and the bottom of the lens is secured with nylon thread. There is something that I have designed to hold. There is also a lens in which the entire circumference of the lens is held by nylon thread (for example, as shown in Japanese Utility Model Application No. 58-154915).

[The problem that the idea aims to solve]

In the former case, the frame protrudes from the top of the lens,
The glasses themselves are rigid and difficult to fit on your face.
It was also extremely fragile if stepped on.

In the latter case, since the entire circumference of the lens is held by nylon thread, the lens is weakly held and the end of the nylon thread has a complicated structure.

In view of this, the present invention is a frameless type that firmly holds the lens, has a beautiful appearance, and also allows the ends of both the metal wire and nylon thread for holding the lens to be easily and firmly engaged. The purpose is to do so.

[Means to solve the problem]

A thin metal wire is fitted along the upper part of the lens in the fitting groove provided on the outer peripheral surface of the lens, a nylon thread is fitted and supported in the groove at the lower part of the lens, and a wire is attached to the outer end of this wire. An end piece to which a temple is attached is provided with a bridge and a nose pad on the inner end side to connect the metal wires of both left and right lenses, and the end of the metal wire that holds the lens is inserted into this end piece. A U-shaped groove for locking and two holes for inserting and locking the end of the nylon thread are respectively formed. As a result, the frame body has a beautiful design and is highly flexible, making it easy to fit the eyeglass frame to the face.

〔Example〕

The present invention will be explained below based on embodiments shown in the drawings.

In the figure, 1 is a thin metal wire (eye wire) designed to hold a lens L that has been ground into a desired shape.The material used is a material that has the desired strength even if a thin wire is used as the eyeglass frame. To enhance its beauty, it is plated with silver or gold, or colored. Then, the metal wire 1 is formed to have an appropriate length and a curve on the upper surface of the lens so that it is disposed not around the entire outer periphery of the lens L but at least only at the upper part, or is formed into an appropriate curve or shape. The lens is later cut to fit this wire shape. An end piece 2 is integrally provided on the outer end side of this metal wire, and a desired temple 3 is provided on this end piece 2 via a hinge 3a so as to be freely foldable. A bridge 4 is constructed so as to connect the wires 1 and 1. A desired nose pad 5 is provided protruding from this bridge 4.

The metal wire 1 and the end piece 2 are connected by fitting the wire end into a groove approximately equal to the diameter of the wire provided on the end piece and directly welding the wire and the end piece.In order to reinforce this welded part, A reinforcing piece 6 may be provided on the end piece to protrude along the direction of the metal wire, and this reinforcing piece may be arranged along the outer surface of the wire. Alternatively, the end of the wire 1 may be bent into a U-shape or other shape and inserted into a groove 2a provided in the end piece, and the wire end and the end piece may be welded together. In this case, the part of the wire that is close to the lens surface is not welded to the end piece, but the tip of the wire that has been fitted into the groove of the end piece is welded to the end piece.
This prevents the strength of the wire on the lens surface from being impaired during welding.

In addition, a part of the bridge 4 provided on the inner end side of the metal wire 1 is integrally formed with an engaging piece 41 on the inner end surface of the lens L, and this engaging piece 41 is attached with a nylon thread (or a soft synthetic resin thread). ) A hole 41a for inserting and locking one end of the lens is bored, and the end piece is also provided with a locking piece 21 on the outer end surface of the lens.
This engaging piece 21 is also bored with a hole 21a, and this hole 21
The other end of the nylon thread 7 is inserted through and locked in a, and the nylon thread 7 and the metal wire 1 form a loop to hold the outer peripheral surface of the lens L. In this case, a nylon thread and a metal wire are fitted into a groove La cut into the outer peripheral surface of the lens, and both the nylon thread and the wire are hidden from view from the entire surface of the lens.

[Effect of idea]

According to the present invention, the outer periphery of the lens is held by a metal wire at the top and a nylon thread at the bottom, and the ends of both are inserted into the end piece and locked at the same time. This nylon thread absorbs errors during lens grinding, making it possible to securely attach the lens without causing any cracks in the lens.Also, it is easy to adjust the lens, and the grooves carved on the outer surface of the lens The nylon thread and wire are completely fitted together,
Because it is invisible from the outside in front of the lens, the design is more innovative than before, and the frame itself is extremely flexible, making it easy to fit around your face.
It has the advantages of not causing discomfort when wearing glasses, being hard to break even if stepped on by mistake, and being lightweight.

[Brief explanation of the drawing]

FIG. 1 is an external view showing the entire eyeglass frame, FIG. 2 is a side view of the main parts, and FIG. 3 is an explanatory view of the joint between the metal wire and the end piece. 1 is a metal wire, 2 is an end piece, 2a is a groove, 21 and 41 are engagement pieces, 21a and 41a are holes, 3
3a is a hinge, 4 is a bridge, 5 is a nose pad, 6 is a reinforcing piece, 7 is a nylon thread, and L is a lens.
