2. Description of the Related Art As a conventional spectacle frame having a spring hinge, the one using a spring as a spring element, as represented by Japanese Patent Laid-Open No. 6-242406, has been the mainstream. This kind of spectacle frame is such that when the temple is further opened from the spectacle-wearing state in which the temple is opened to the reference position, the spring is compressed so that its elastic reaction force acts, and the spectacles are smoothly attached and detached. You can do it,
It was a big feature that the fit of the temple could be improved. On the other hand, this type of spectacle frame also has some drawbacks associated with the complex structure for compressing the spring.

Therefore, as a means to overcome the drawback,
As disclosed in Japanese Patent Application No. 10-9090 and Japanese Patent Application Laid-Open No. 2001-1000158, a spectacle frame using a leaf spring as a spring element has also been proposed. Generally, these techniques provide a leaf spring (spring member, spring piece) on one of the armature and the temple, which are connected via a hinge, and a pressing portion (pressing protrusion, abutting piece) on the other. When the eyeglasses are further opened from the state of wearing the eyeglasses, the leaf springs are pressed by the pressing portions to bend and the elastic reaction force of the leaf springs acts.

[0004]

The above-mentioned conventional spectacle frame using a leaf spring does not require a structure for compressing the spring, and a hinge using a spring while ensuring the original effect of the spring hinge. Although exhibiting different characteristics, a spectacle frame with a simpler structure and a good-looking appearance has been desired. Further, in any of the above-mentioned conventional eyeglass frames using a leaf spring, there is room for improvement in that the leaf spring or the pressing portion projects outward when the temple is folded. In particular, in the spectacle frame described in Japanese Patent Application No. 10-9090, the leaf spring has the leaf spring on the temple side of the wearer even when the temple is further opened from the spectacle wearing state, as shown in, for example, FIG. It will stick out greatly. Further, the spectacle frame having the spring hinge has a problem that it is difficult to adjust the fitting.

An object of the present invention is to provide a technique for realizing an eyeglass frame having a spring hinge using a leaf spring with a simple structure and good appearance. An object of the present invention is to prevent a member relating to a spring hinge from protruding outward when a temple is folded in an eyeglass frame having a spring hinge using a leaf spring. It is an object of the present invention to allow an inexperienced salesperson to easily adjust the fitting of a spectacle frame having a spring hinge.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to FIGS. [First Embodiment] FIG. 1 is a plan view of eyeglasses according to a first embodiment. In the figure, reference numerals 2 and 2 denote left and right eyeglass lenses, respectively.
Are connected by a bridge 3. Further, the end pieces of the spectacle lenses 2 and 2 are provided with the end pieces 4 and 4, respectively. Further, temples 6 and 6 are rotatably and pivotally connected to each of the end pieces 4 and 4 via hinges 5 and 5, respectively, to form a pair of glasses 1. In addition, in the bridge 3,
A nose pad or the like (not shown) is provided.

Specifically, as shown in FIG. 2, each temple 6 has a temple body 62 having a temple end.
And a connecting member 61 attached so as to extend the temple body 62 to the front side of the glasses. Then, as shown in FIG. 3, the connecting member 61 and the end piece 4 are connected via the hinge 5, so that the temple 6 can be opened and closed while forming the joint 52 with the respective members 4 and 61. There is. Further, as will be described later in detail, the pressing member 43 is provided on the end piece 4, and the leaf spring (cantilever) 7 as an elastic member is provided on the connecting member 61.
Together with these hinges 5, they function as a so-called spring hinge (see FIG. 6).

As shown in FIG. 3B, the hinge 5 is in a state in which the male hinge piece 41 provided on the armature 4 and the female hinge piece 611 provided on the connecting member 61 are fitted to each other. , And these are pivotally connected by a hinge shaft 51.
More specifically, the male hinge piece 41 is formed by reducing the thickness of a part of the armature 4 in the direction perpendicular to the paper surface, and at that part, the hinge shaft 5 is formed.
A through shaft hole through which 1 passes is formed. On the other hand, the female hinge piece 611 forms a part of the connecting member 61 into a bifurcated shape,
A through shaft hole through which the hinge shaft 51 penetrates is formed in that portion. Then, for example, a hinge shaft 51 formed in a screw shape is used, and the screw is screwed into a thread groove formed in one of the through shaft holes of the bifurcated structure of the female hinge piece 611, and the hinge 5 is inserted.
Are configured.

As shown in FIG. 3, the male hinge piece 41 provided on the armature 4 is provided with a first scale 41a, while the female hinge piece 611 provided on the connecting member 61 is provided with a second scale. The scale 611a is attached. These first scales 41
The a and the second scale 611a are aligned when the temple 6 is opened to a position (hereinafter, referred to as "reference position") indicated by an imaginary line (two-dot chain line) in FIG. The visual confirmation means for visually recognizing the quality of the fitting is configured.

Further, as shown in FIG. 3, in the hinge 5, an end portion 42 of the end piece 4 on the side of the connecting member 61 and an end portion 612 of the end piece 612 of the connecting member 61 constitute a joint 52. When the temple 6 is opened and expanded at a predetermined angle (for example, 5 degrees) or more, the end portions 42 and 612 come into contact with each other, and the abutment 52 is closed, so that the temple 6 is prevented from further expanding and expanding. ing.

In FIG. 3B, reference numeral 43 is a pressing portion provided at the end portion 42 of the end piece 4. The pressing portion 43 is formed integrally with the end piece 4. In addition,
Since the tip 71 of the leaf spring 7, which will be described later, is projected to the pressing portion 43, it is preferable to cure the tip 71. Further, the pushing portion 43 and the main body of the armoring member 4 may be formed as separate members.

FIG. 4 is an exploded view around the connecting member 61. As shown in the figure, the connecting member 61 has a mounting portion 613 for mounting the leaf spring 7, and the mounting portion 61
The leaf spring 7 is attached to the plate 3 with its free end (tip 71) facing the abutment 52. The material of the leaf spring 7 is not particularly limited, but in addition to flexibility, corrosion resistance, abrasion resistance,
A material having at least one of plastic deformation resistance is preferable.

No brazing is used around the leaf spring 7 to avoid the blunting of the leaf spring 7 due to heat. Specifically, the leaf spring 7 is arranged so as to extend in the direction along the main extension line of the temple 6 (vertical direction in FIG. 4), and only the end on the temple 6 side is riveted to the mounting portion 613. It Thereby, the leaf spring 7 constitutes a cantilever. By rivet-joining the leaf spring 7 and the mounting portion 613, the eyeglasses 1
Can be easily manufactured. The penetration direction of the rivet 614 is substantially the same as the thickness direction of the temple 6 in a plan view. Further, it goes without saying that the leaf spring 7 can be replaceably mounted.

In FIG. 4, for convenience of explanation, the connecting member 61 is shown in a sectional view, but the connecting member 61 is configured to cover the portion of the leaf spring 7 excluding the tip 71 and the one surface 72 (FIG. 1). , See FIG. 2). Therefore, as shown in detail in FIG. 2B or FIG. 5, the back surface of the leaf spring 7 (the surface on the temple side)
Is not exposed, but one surface 72 thereof is exposed to the outside. Therefore, the one surface 72 of the leaf spring 7 is provided with a predetermined marking, plating, or other decoration to make the spectacles 1
It is possible to improve aesthetics and luxury while simplifying the overall structure.

Further, an opening 615 is formed at the end 612 of the connecting member 61, and when the leaf spring 7 is attached to this connecting member 61, a natural state (a state where the leaf spring 7 is not bent) is formed. ), The tip (free end) 71 of the leaf spring 7 slightly protrudes from the opening 615. That is, the temple 6 is configured to receive the tip 71 of the leaf spring 7 in a retractable manner at the opening 615 formed at the end 612.

The ends 612 of the connecting member 61 are substantially parallel to the direction along the main extension line of the temple 6 (vertical direction in FIG. 4), but the tip 71 of the leaf spring 7 is directed toward the abutment 52. By plastically bending, the tip 71 of the leaf spring 7 can be retracted from the opening 615. The connecting member 61 has a plan view of the spectacles 1 (see FIG. 1) not only when the tip 71 of the leaf spring 7 projects from the opening 615 but also when the tip 71 is completely immersed in the connecting member 61. ), The plate spring 7 has such a width that it does not protrude outward from the connecting member 61.

The operation of the spectacles 1 configured as described above is as follows. When the temple 6 is opened from the folded state to the reference position, the leaf spring 7 starts to bend with the abutment 52 having a predetermined gap (see FIG. 6A). That is, when the temple 6 is opened to the reference position, the tip 71 of the leaf spring 7 and the pressing portion 43 come into contact with each other at a position substantially opposite to the hinge 5, that is, at the abutment 52. At this time, the leaf spring 7 does not bend, and the abutment 52 is slightly open. At this time, the first scale 41a attached to the hinge 5 and the second scale 611a are aligned.

This state (hereinafter referred to as "reference state")
When the temple 6 is further opened, the leaf spring 7 bends while the tip 71 of the leaf spring 7 hits the pressing portion 43 in association with the opening, and the restoring force acts as a spring force that returns the temple 6 to the reference position. Specifically, in the process of further opening the temple 6 from the reference state, the tip 7 of the leaf spring 7 is
1 pushes the pushing portion 43 and the front direction of the glasses (see FIG. 6).
While sliding in (inward and downward), it retracts into the connecting member 61.
At this time, since the temple 6 is biased by the leaf spring 7 in the direction of returning to the spectacle wearing state, the spectacles 1 can be smoothly put on and taken off, and the temple 6 can be fitted well and the spectacles when wearing the spectacles can be improved. The stability of 1 can be improved.

Then, when the temple 6 is further opened from the reference state by a predetermined angle (for example, 5 degrees) (the state shown by the solid line in FIG. 1), the main body of the armoring member 4 and the main body of the connecting member 61 come into contact with each other, and When 52 is completely closed, further bending of the leaf spring 7 is prevented. At this time, the tip 71 of the leaf spring 7 is completely retracted inside the connecting member 61 (see FIG. 6B). At this time, the first scale 41a attached to the hinge 5 and the second scale 611a are misaligned. At this time, the amount of bending of the leaf spring 7 becomes maximum,
In the plan view of the eyeglasses 1 (see FIG. 1), the leaf spring 7 does not protrude outward from the connecting member 61.

The fitting adjustment of the spectacles 1 will be described below. When the spectacles 1 are worn, it is preferable to adjust the fitting so that the spring force of the leaf spring 7 does not act on the temples. This is because if the spring force is constantly applied when wearing the spectacles, the wearer may feel tired when wearing the spectacles for a long time. In this glasses 1, the temple 6
When the is opened to the reference position, the spring force starts to act with the abutment 52 having a predetermined gap,
By looking at the gap of the abutment 52 when the eyeglasses 1 are actually worn, and whether or not the gap coincides with the predetermined gap, even a salesperson with little experience can easily determine the quality of the fitting.

For example, when the gap between the abutments 52 when the spectacles 1 is actually worn becomes narrower than the predetermined gap, it is understood that the spring force acts on the temple of the wearer at that time. . In this case, the salesperson or the like makes adjustments such as bending the frame to widen the gap between the abutments 52 to the predetermined gap at the time of wearing so that the spring force does not act at the time of wearing.

Further, by comparing the distances between the left and right joints 52, 52, even a salesperson with little experience can easily determine the quality of the fitting depending on whether or not they match. In the glasses 1, as shown in FIG.
Since both 2 and 52 are arranged on the front side of the spectacles (downward in FIG. 1), the distance between the left and right abutments 52 and 52 can be compared at the same time. When the salesperson or the like determines that the gap between the joint openings 52 is different between the left and right, the salesperson or the like matches them by adjusting the frame or the like.
At this time, it is preferable that the distance between the left and right abutments 52, 52 is matched with the predetermined distance.

As described above, the quality of the fitting can be sufficiently determined by checking the distance between the abutments 52. However, in this spectacle 1, since the hinge 5 is provided with the first scale 41a and the second scale 611a. Also, the quality of the fitting can be more surely visually recognized depending on whether or not the scales are aligned. In addition, the first scale 41a and the second scale 61
The method of attaching 1a is not particularly limited, and for example, whether or not the deviation angle of the temple 6 from the reference position is within the allowable range may be visually recognized.

According to this embodiment, the following effects can be obtained. (1) With the above configuration, the glasses 1 are actually
When wearing, the opening degree of the abutment 52 or the first and second
By observing the scales 41a and 611a of the above, it is possible to estimate the magnitude of the elastic reaction force of the leaf spring (cantilever beam) 7 acting at that time, so that adjustment or maintenance of other parts of the spectacle frame, such as temple ends, can be performed. Can be done accurately. As a result, it is possible to realize the spectacles that give the optimum wearing feeling.

(2) While the free end 71 of the leaf spring (cantilever) 7 is made to face the abutment 52, a pressing portion 43 is provided at the end 42 of the end piece 4 to form a spring hinge. The tip 71 of the leaf spring (cantilever) 7 and the pressing portion 4 are substantially opposed to each other.
3 and 3 are brought into contact with each other, and it is possible to prevent the leaf spring (cantilever) 7 and the pressing portion 42 from protruding outward when the temple 6 is folded.

(3) When the temple 6 is further opened from the state of wearing spectacles, the pressing portion 42 is made to be pushed by the tip of the leaf spring (cantilever) 7, so that the leaf spring (cantilever) is also held at this time. The tip 71 of the beam 7 does not protrude outward.

(4) The leaf spring (cantilever) 7 has its tip 7
Since 1 bends while pushing the pressing portion 43, the abrasion resistance and the deformation resistance of the leaf spring (cantilever) 7 are higher than, for example, the case of pressing a portion in the longitudinal direction of the cantilever. You can improve the property.

(5) Since the end pieces 42 and 612 are connected to each other so that the end pieces 42 and 612 form the abutment 52, the armature 4 and the temple 6 are bent when the leaf spring (cantilever) 7 is bent more than a predetermined amount. ,
The closing of the abutment 52 prevents further bending. As a result, not only the plastic deformation of the leaf spring (cantilever) 7 can be prevented, but also its fatigue can be reduced, and as a result, the life of the leaf spring (cantilever) 7 can be extended.

(6) Since the temple body 62 and the connecting member 61 are separate members, and the connecting member 61 is provided with the leaf spring (cantilever) 7, the stress generated at the spring fulcrum (rivet joint) of the leaf spring 7 It is possible to avoid directly contacting the temple body 62, and as a result, the durability of the temple 6 can be improved. Further, for example, if the temple body 62 is made of wood and the connecting member 61 is made of metal to provide an accent, the aesthetics and high-class feeling of the glasses 1 can be further improved.

(7) Since the one surface 72 of the leaf spring 7 (cantilever) is exposed to the outside, liquid such as water does not collect at the place where the leaf spring 7 is arranged (connecting member 61). It is possible to prevent the leaf spring 7 (cantilever) from corroding. Further, by decorating at least one surface 72 of the leaf spring 7 (cantilever), the spectacle frame or the spectacles 1 in which the configuration is simplified and the aesthetic appearance is balanced is realized.

(8) Since one surface 72 of the leaf spring 7 (cantilever) is exposed, the degree of bending of the leaf spring can be visually recognized at that portion, and the magnitude of the spring force can be estimated more accurately. As a matter of course, it becomes possible to confirm the fatigue condition and the like, and it becomes possible to perform the maintenance more accurately even in an eyeglass store or the like.

[Second Embodiment] For the same configuration as the first embodiment, the second embodiment will be described below using the same reference numerals for convenience.

In the second embodiment, as shown in FIGS. 7 to 9, the connecting member 9 has a tip 11 of the leaf spring 10, a part 12 of the back surface (the surface on the temple side), and a surface 13. It is configured to cover the part except. Therefore, although the back surface part 12 and the front surface 13 of the leaf spring 10 are exposed to the outside, the leaf spring 1
By connecting 0 with a noble metal such as 18 gold, the connecting member 9
It is possible to further improve the aesthetics and classiness of the spectacles while reducing the weight and simplifying the spectacles. It should be noted that a part of the back surface 12 of the leaf spring 10 may be provided with a predetermined marking or other decoration.

Further, the leaf spring mounting portion 92 of the connecting member 9 is

Further, as shown in FIG. 9, the male hinge piece provided on the armature 8 is provided with a first scale 8a, while the female hinge piece provided on the connecting member 9 is provided with a second scale. 9a is attached. These scales 8a and 9a are aligned when the temple 6 is opened to the reference position, so that the quality of the fitting can be visually recognized accurately.

The operation of the spectacles constructed as above is as follows. First, when the temple 6 is opened from the folded state to the position shown by the phantom line (two-dot chain line) in FIG. 1, the tip 11 of the leaf spring 10 and the convex portion 81 contact at a position substantially opposite to the hinge 5. (See FIG. 9A). Specifically, as the temple 6 expands, the convex portion 81 enters the inside of the connecting member 9 through the opening 91, and the peak and the leaf spring 10 are inserted.
Contacts the tip 11 of the. At this time, the convex portion 81 does not completely enter the inside of the connecting member 9, and the abutment 52 is slightly open. Also, at this time, the first scale 8 attached to the hinge
a and the second scale 9a are aligned.

Next, when the temple 6 is further opened from this reference state, the convex portion 81 causes the tip 11 of the leaf spring 10 to move.
The leaf spring 10 bends while being pushed by the elastic force of the leaf spring 10. In detail,
In the process of further opening the temple 6 from the standard state,
