Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle frame having a so-called spring hinge in which a temple is opened outwardly with a spring property from a state where the temple is opened so as to be in a spectacle wearing state, and the spectacle frame is used. About glasses that were.

[0002]

2. Description of the Related Art There is known an eyeglass frame having a so-called spring hinge in which a temple is opened outward with a spring property from a state where a temple is opened so as to be in a state of wearing glasses. The spectacle frame having the spring hinge has been proposed for the following purpose. (1) Make it possible to attach and detach glasses smoothly. (2) It is possible to reduce a large deformation of the spectacle frame when a large external force is applied to the spectacle frame during wearing. (3) When a large external force is applied to the spectacle frame during wearing, the possibility of breaking the spectacle frame is prevented, and the safety of the wearer is more completely ensured.

[0003] As a spectacle frame having a spring hinge,
For example, those described in JP-A-6-242406 and those described in JP-B-7-3515 are known. Japanese Patent Application Laid-Open No. 6-242406 discloses a temple in which a spring can be slid with respect to a temple-side hinge while compressing a spring. Thereby, the temple can be further opened outward with spring properties from the opened state.

[0004] In Japanese Patent Publication No. 7-3515, for example, a hitting claw is provided on the peripheral movable end of a temple-side hinge, and a spring which comes into contact with this hitting claw when the temple is opened is provided on the armored side. It is a thing. Thus, the temple can be further opened outward with spring properties.

[0005]

However, the structure described in JP-A-6-242406 has a complicated structure for allowing the temple to slide with respect to the temple-side hinge while compressing the spring. Therefore, the overall shape is large and the manufacturing cost is high. In addition, if the spring design keeps the hinges pressed all the time, a special jig will be required for assembly, making it difficult to replace or repair the temple at the store. Occurs. Further, when the spring portion has a closed box shape and moisture or the like invades, corrosion sometimes becomes a problem.

[0006] Further, in Japanese Patent Publication No. 7-3515, a plurality of parts must be further joined to a hinge portion formed integrally by brazing, and a claw (spring structure) must be formed. Therefore, there is a high possibility that the spring portion of the claw is thermally affected at the time of brazing and the spring property is reduced. Therefore, the required spring elasticity may not be maintained. In addition, there are many structural and design restrictions such as the need to reduce the size of the hitting claws because the spring structure is formed in the hinge portion. Therefore, there is also a problem that it is difficult to sufficiently maintain spring characteristics and durability such as abrasion resistance in long-term use, or to sufficiently realize design considerations for safety.

The present invention has been made in view of the above points, has a simple configuration, has few restrictions on design and structure, has sufficient functions and durability, and is easy to manufacture and repair. It is an object of the present invention to provide an eyeglass frame having a spring hinge.

It is a spectacle frame characterized by selecting the arrangement structure of the piece and the contact portion.
The second means includes: (2) providing a second contact portion that contacts the elastic piece so as to prevent further deformation when the elastic piece contacts the contact portion and deforms by a predetermined amount or more. The eyeglass frame according to the first means, characterized in that:
A third means is that (3) the elastic piece is formed integrally with the yoroi or temple.
Alternatively, it is an eyeglass frame according to the second means. The fourth means is: (4) The first to third elastic members are characterized in that the elastic piece is formed of a separate member from the yoroi or temple and is fixed to the yoyo or temple by fixing means. It is an eyeglass frame concerning any one of means. A fifth means (5) is the spectacle frame according to any one of the first to fourth features, wherein the contact portion is formed integrally with the yoroi or the temple. The sixth means is (6) wherein the abutting portion is formed of a separate member from the yoke or temple and is fixed to the yoke or temple by a fixing means. 5 is an eyeglass frame according to any one of the first to fifth aspects. A seventh means is (7) spectacles using the spectacle frame according to any one of the first to sixth aspects.

[0009]

According to the above structure, the temple is released from the folded state, and the temple is opened to put on the spectacles,
When the temple is operated in the further opening direction, the arrangement of the elastic piece and the contact portion is selected in such a manner that the elastic piece abuts on the contact portion and deforms the contact portion, so that the open state is selected. The temple can be further opened outward with a spring property. In addition, one end of the elastic piece is fixed to a position of the hinge or the temple away from the hinge structure, and the contact portion is provided at a position of the other of the hinge or the temple away from the hinge structure. I have. For this reason, the degree of freedom in designing the spring structure using the elastic pieces and the contact portions is significantly increased, and there are very few structural and design restrictions. As a result, consideration for durability such as maintenance of spring properties and wear resistance in long-term use, or
It is now possible to sufficiently realize design considerations for wearing comfort and safety.

FIG. 4 is a partial cross-sectional view of an eyeglass frame according to the first embodiment of the present invention. Hereinafter, an eyeglass frame according to a first embodiment of the present invention will be described with reference to these drawings. This embodiment is an example in which the present invention is applied to glasses using a so-called rimless frame.

In these figures, reference numeral 1 denotes left and right spectacle lenses.
The left and right lenses 1 are attached to the left and right ends, respectively. Further, a temple 4 is attached to each of the yoroi 2 via a hinge 3 so as to be openable and closable to form glasses. Bridge 5
Is provided with a nose pad 6.

FIG. 4 is a sectional view of the vicinity of the hinge 3. As shown in FIG. 4, in the hinge portion 3, a female hinge piece 34 formed on the temple-side end of the temple 4 is fitted into a male hinge piece 32 formed on the temple-side end of the temple 2. ,
The hinge shaft piece 31 is penetrated and attached to these.

That is, the male hinge piece 32 has a through-hole portion into which the hinge shaft piece 31 is fitted by forming the end of the yoke 2 thin in the direction perpendicular to the plane of the paper. The female hinge piece 34 has a structure in which the end of the temple 4 has a bifurcated structure, and the male hinge piece 32 is inserted into the bifurcated portion. Similarly, a through shaft hole is formed in the female hinge piece 34, and the hinge shaft piece 31 is attached so that the male hinge piece 32 is fitted into the female hinge piece 34 so as to penetrate these male and female hinge pieces. Have been. Thus, the temple 4 is attached to the yoke 2 so as to be openable and closable.

The hinge shaft piece 31 is, for example, formed in a screw shape, and is screwed into a threaded structure formed in one of the through-shaft holes of the bifurcated piece of the female hinge piece 34. Is fixed by the method.

An abutting piece 2 (abutting portion) is attached at a position near the temple side of the yoke 2 but away from the male hinge piece 32. The abutment piece 21 has a substantially arch shape, and has a base fixed to the yoke 2 by a screw 22 and a distal end provided with a spring piece 41 provided on the temple 4 in a state where the temple 4 is opened. It is formed so as to abut.

The spring piece 41 is provided with
The end on the side of the flap is arranged in the elongated hole 43 provided at the side of the side so that the end is a free end, and the end on the opposite side is screwed to the step 44 for fixing provided on the temple 4. It has a fixed, so-called cantilever structure. In this embodiment, the end of the elongated hole 43 on the side of the yoke is closed to form a stopper piece 35 (second contact portion).

In the above-described configuration, the temple-side tip of the contact piece 21 has the temple 4 folded (not shown).
In this case, the spring piece 41 is not brought into contact with the spring piece 41 but in a state in which the temple 4 is opened (the state shown in FIG. 4A) to put the glasses on. When the temple 4 is opened further, an elastic force opposing it is applied (the state of FIG. 4B).

The opening angle α from the wearing state (FIG. 4)
When (see (B)) becomes, for example, 5 degrees, the spring piece 41
Is stopped by the stopper piece 35 at its tip. That is, in this case, the spring piece 41
Has a so-called doubly supported structure. Therefore, when the temple 4 is further opened, the opening angle from the wearing state is α (for example,
5 °) or more (see FIG. 4).
(C)), but it requires a very large force.

That is, only a relatively weak elastic force acts up to the opening angle α. However, if it is attempted to open to an angle β larger than that, a strong elastic force acts.
Thus, when the opening angle is equal to or greater than a certain angle (for example, 5 °), it is difficult to further open the opening angle. Therefore, even if a strong force is inadvertently applied,
The possibility that the frame is deformed can be effectively prevented.
