Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is intended to improve eyeglass temples,
In detail, the glasses are extremely tough and comfortable to wear, and the glasses using them are designed to fit the face, temporal and ear parts stably even during intense exercise and do not fall off. The present invention relates to a composite winding structure.

[0002]

2. Description of the Related Art Ear ears (t) in temples of eyeglasses have conventionally been used.
The "emple end" is called "curl side" (curl side), which is made by densely winding a metal wire into a coil. Such rope-handed temple eyeglasses can largely surround the base of the ear, have soft elasticity, and are more comfortable to wear than usual.

However, the above-mentioned conventional rope-handed temple ear hook portion has a structure in which a metal wire is simply wound in a coil shape, so that it is too soft and has a weak waist. There is a drawback that the temple ear hooks extend due to inertia and come off the ears and the glasses fall off the face.

Attempts have been made to use a springy strong metal wire in an attempt to overcome the drawbacks of such a rope-handed temple ear hook, but then the ear hook becomes abnormally hard. As a result, the original softness was lost and the comfort was worse, and it could not be an effective solution.

[0005]

[Technical problem to be solved] The present invention has been made to eliminate the drawbacks of the rope-handed temple ear hook portion of the conventional glasses, and has excellent toughness and stable even during intense exercise. An object of the present invention is to provide a rope hand-like spectacle temple that is fit to a face, a temporal region and an ear portion, and does not fall off and has high form stability.

[0006] Further, another technical problem of the present invention is as follows.
It is an object of the present invention to provide a complex winding structure of a spectacle temple that is stiff and has a good wearing comfort that can be used for a temple requiring flexibility.

[0007]

Means adopted by the present inventor for solving the above technical problem will be described below with reference to the accompanying drawings.

That is, the present invention provides, as a means for solving the above technical problem, a temple T in which the free end side or the base side of the temple base 1 ′ is linearly stretched to form the core wire 1;
A base metal wire 2 tightly coiled around the core wire 1 of the temple T; and a coil wound further around the base metal wire 2 in the opposite direction to the base metal wire. The present invention is characterized in that the metal wire rods of the respective layers are brought into close contact with each other by adopting the coating layer metal wire rod 3 and plastically deforming the composite wire rod portion of the temple T forming the metal wire rods 2 and 3. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a perspective view of a pair of eyeglasses using the temple of the first embodiment constructed by applying the present invention to a temple ear hook, and FIG. 2 is an enlarged view of a part of the temple ear hook of the first embodiment. FIG. 3 is a partially enlarged perspective view showing a winding structure, and FIG. 3 shows a winding structure constituting a temple ear hook portion of the first embodiment by unwinding the metal wires of each layer in a stepwise manner and applying a swaging process to the metal wires. FIG. 4 is a side view showing a second embodiment in which the present invention is applied to the base of the temple, and FIG. 5 is a side view showing the temple of the second embodiment. It is an enlarged side view of a base part.

In FIG. 1, what is indicated by reference numeral G is two-point type rimless glasses, left and right lenses L, L, a nose bridge B connecting these lenses L, L at the center, and And a temple T hinged via a strap SS for fastening to a shoulder portion of the connected lens L.

[0011] The present invention first embodiment products have been used to MimiKake portion T _M of the temple T of the rimless eyeglasses G illustrated in FIG. That is, the temple T in the rimless glasses G of FIG. 1 is formed by extending the free end side of a round bar-shaped 18-gold (Au-Cu alloy) base material 1 'to a diameter of 0.4 mm to form a core wire 1. Four base-layer metal wires 2 each made of the same 18 gold having a diameter of 0.3 mm and four coating metal wires 3 each made of the same 18 gold having a diameter of 0.3 mm are wound around the core wire 1. -The appearance of the temple ear hooks T _M is designed in design by attaching a decorative ball D to prevent unwinding of 3.

The product of the first embodiment has a cross-sectional structure as shown in FIG. 2, and a specific form of the winding is shown in FIG. That is, in the product of the first embodiment shown in FIG. 3, four core metal wires (18 gold) 2
Is wound tightly in a Z-twist (the right part of FIG. 3), and four coated metal wires 3 are aligned from above on the base metal wire 2 wound in such a manner and coiled closely in an S-twist (FIG. 3).
, The outer periphery of the winding material (1, 2, 3) wound in this way is subjected to swaging so that the peripheral surface becomes a smooth surface P.
(The left part in FIG. 3).

The product of the first embodiment having such a structure is as follows.
The elasticity characteristics of the Z-strand base metal wire 2 and the S-strand coated metal wire 3 surrounding the thin core wire 1 are combined to exhibit extremely tough bending properties, and the same material of the same diameter (18 gold) Feels better than a single-piece temple ear hook and a synthetic resin ear hook cover (JIS term: modern) over the temple end, and the ears of the spectacle wearer. It shows the function to keep it in a stable state.

The second embodiment shown in FIGS. 4 and 5 relates to an eyeglass temple T constructed by applying the present invention to the base side of the temple. Temple T using the product of the second embodiment
Is connected to a strap S via a hinge H, and is wound and fixed to the hinge H (second winding material).
Example product), a temple bar T 'brazed to the other end of the winding material, and a synthetic resin ear cover M attached to the tip of the temple bar T'. Have been.

Thus, the structure of the product of the second embodiment applied to the base side of the temple T is the same as that of the first embodiment in order to enhance the decorative effect.
As in the case of the product of the example, as a material of the base metal wire 2 and the coated metal wire 3, four Au-Cu alloy (18 gold) wires each having a diameter of 0.3 mm were used, and the coils were tightly wound into Z twist and S twist. The core wire 1 is made of Ni with a diameter of 0.3 mm.
-A Ti-based superelastic alloy is used.

The temple T thus manufactured using the product of the second embodiment on the base side has the superelastic properties of the Ni-Ti superelastic alloy constituting the middle core wire 1 in addition to the S and Z coil windings. In combination with the elasticity characteristics of the base metal wire 2 and the coating metal wire 3 to be wound, it exhibits a very tough flexural property that is subtly harmonious and only hard and only soft. In the glasses using this, the temples T softly and stably hold both sides of the wearer's heads without causing any pain, and the glasses are detached even if subjected to intense exercise and strong vibration. The danger of accidents can be prevented.

Although the embodiments illustrated in the present specification are generally as described above, the present invention is not limited to the above-described embodiments, and various descriptions may be made within the description of “claims for registering utility models”. The design can be changed, and in the above-described embodiment, only the case where the core wire 1 is made of metal is exemplified.
It is also possible to use a high elasticity engineering plastic material such as polyphenylene sulfide resin or a high elasticity carbon fiber, which belongs to the technical scope of the present invention.

Further, in the above embodiment, only the case of a gold alloy (18 gold) as a material of the base metal wire 2 and the coating metal wire 3 is exemplified. However, instead of this, a Ni-Ti superelastic alloy is used. It is naturally possible to form a coil by combining a metal wire rod with a shape memory alloy or a Ni-Ti superelastic alloy and another kind of metal wire. Such a design change also belongs to the technical scope of the present invention.

Further, in the above-mentioned embodiment, the core wire 1, the base metal wire 2 surrounding the core wire 1 in a coil shape, and the coated metal wire 3 further surrounding the core wire 1
However, it is free to further cover the metal wire with a coil wound on it, and on the other hand, a soft synthetic resin is applied to the peripheral surface of the metal wire wound on the outermost layer. Making design changes such as laminating,
It can be said that it naturally belongs to the technical scope of the present invention.
