Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple for a spectacle frame, which is capable of stably wearing glasses without a nose pad.

[0002]

2. Description of the Related Art In eyeglasses, a nose pad is put on the nose to support a front portion, and temples extending from both sides of the front portion are hooked on ears. In other words, it has a four-point support configuration with two nose pads and two temples. By the way, the vines of general spectacle frames are foldably connected to each other via hinges, and the two hinge pieces constituting the hinges are brazed to the inner side surfaces of the end portions of the armature and the vines attached to both sides of the front part. The crane can be folded against the armor that is fixed to the front part.

However, a vine connected via a small hinge cannot sustain a stable folding operation for a long time. That is, a small hinge loosens its shaft screw or wears a sliding surface, which causes rattling of the vine. As a result, the spectacles worn may be misaligned or sometimes come off.

Since the vine has some elasticity, it can be slightly curved to fit the face. However, it is only for a short period of time after purchasing eyeglasses that the eyeglasses worn on the face are not misaligned only by the spring characteristics of the vine. The spring characteristics of the vine itself are always constant depending on the material unless it is bent and plastically deformed extremely, and it can return to its original shape when the force is removed. Since the rattling occurs, it is not possible to hang the tip of the vine on the ear to fit the side of the face and the head.

By the way, as one means for solving such a problem of the spectacle vine, a joint called a spring hinge as shown in FIG. 7 is used for fitting the vine from the face to the head. That is, the basic idea of the spring hinge is to braze a fixed butterfly piece (b) to the armor (a) and fix the other butterfly piece as a sliding butterfly piece (c) to allow sliding for a certain distance. This allows the crane to be opened outward.

A guide groove is formed in the temple (d), and the sliding butterfly piece (c) slides using the guide groove as a guide. A coil spring is provided in the internal cavity of the sliding butterfly piece (c). When (e) is accommodated and the crane (d) is opened to the outside, the sliding butterfly piece (c) is pulled toward the fixed butterfly piece (b) side and compressed. The coil spring (e)
Corresponds to a claw (g) provided at the inlet of the inner cavity of the sliding butterfly (c) and locked in the slot (f) of the claw (d), and the claw (to) functions as a stopper. As a result, the coil spring
The restoring force of (e) acts on the vine (d) to return the vine (d) to its original position.

By the way, a coil spring is attached to the sliding butterfly piece (c).
The hinge structure with the built-in (e) is complicated as shown in the figure, and therefore the manufacturing man-hours increase, and it becomes a hinge with a spring which is expensive in terms of cost. Moreover, since the structure is complicated, there is a problem that it is easy to fail, and once it fails, it is difficult to repair. If the coil spring (e) and the cored bar are pushed into the inner cavity of the sliding butterfly (c) and locked to the claw (g),
(G) and the coil spring (e) cannot be removed.

That is, while the claw (g) is restrained by the guide of the sliding butterfly (c), the engaging piece (h) of the claw (g) is in the slot (f).
Then, the head of the core bar (li) comes into contact with the claw (to) with a spring force, and the force of pushing the locking piece (h) into the slot (f) acts. Therefore, it becomes impossible to remove the claw (g) from the sliding butterfly piece (c), and at the same time, repair becomes impossible.

Of course, there are various other joint structures capable of performing the same function as the spring hinge, and when the glasses are worn, the vine fits from the face to the head. And while the glasses are stable, the nose pads of the conventional type are required on the front of the glasses. Even if the vine fits from the face to the head, it is impossible to wear glasses only with the vine.

The nose pad which is attached to the front part is brazed at one end to the rim and is fixed to the tip of the curved leg with an akigaki, so that the direction can be slightly changed to fit the nose. Therefore, the nose pad puts on the nose and supports the front part to stabilize the worn glasses, but when the glasses are removed, a trace of red discoloration remains on the nose and the makeup is peeled off.

[0011]

As described above, the conventional vine has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a temple of a spectacle frame which can stably wear spectacles without a nose pad.

[0012]

The temple of the spectacle frame according to the present invention functions so that the spectacles can be worn without providing a nose pad on the front portion. In other words, the eyeglass frame to which the nose pad is not attached is targeted, and the eyeglasses are configured so that the eyeglasses do not shift in position and do not come off with only the vine.

In view of this, the vine of the present invention is provided with a contact portion projecting inwardly at an approximately middle portion so that when the spectacles are put on, the corresponding ridge portion fits into the face of the face. The hitting part fits the komekami part to support the front part, and the tip of the vine engages the ear and hits the back of the head.

Here, the specific form of the hitting portion is not limited, and a leaf spring bent inward is attached or a rubber material having excellent elasticity is provided. It is also possible to attach a pad which is biased by a spring force and which projects, and it is also possible to bend the vine inward to form a contact portion. by the way,
The present invention relates to a vine, and the form of the front portion and the joint structure for connecting the foldably to each other are not limited. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an eyeglass frame equipped with the vine of the present invention. The spectacle frame has vines 2 and 2 attached to both sides of a front portion 1, and the vines 2 and 2 can be folded via hinges 3 and 3. And in the front part 1, both rims 4 and 4 into which lenses are fitted are connected through a connecting member 5 as in the conventional eyeglass frame,
The end pieces 6, 6 are brazed to the outer sides of the rims 4, 4 and the vines 2, 2 are connected to the end pieces 6, 6 via the hinges 3, 3.

The vine 2 is made of a thin wire material having an excellent spring property, and a resin modern is inserted at the tip so that it can be locked to the ear.
The plate spring 8 is inserted into the insertion opening of the plate spring and fixed, or brazed and fixed, and a pad 9 is fixed to the tip of the plate spring. The leaf spring 8 is thinner than the crane 2 and has excellent spring properties,
If a pressing force acts on the pad 9, it can be flexibly deformed.

The material of the pad 9 is not limited, but in general, a silicone resin that is in contact with the skin and is hard to slip is suitable. As is clear from the figure, the front part 1 of this spectacle frame is not provided with a nose pad, and when wearing spectacles, both vines 2 and 2 should not come off the face and position. It can be supported so as not to slip.

A resin-made modern 7 inserted into the tip of the temple 2 has a substantially L shape and is locked to the ear, and at the same time, hits the back of the head with an appropriate pressing force. Of course, the shape of the modern 7 inserted into the temple 2 of the present invention is not limited to the general L-shape shown in FIG. Then, the pad 9 attached to the temple 2 can hold down the face mechanism. The vine 2 supports glasses by a modern 7 located at the tip of the vine 2 and a pad 9 in an intermediate portion contacting the back of the head and the two points of the mechanical mechanism.

FIG. 2 shows another embodiment of the vine according to the present invention. The vine 2 is provided with a leaf spring 10 which is curved and protrudes inward. One end 11 of this leaf spring 10 is a hook 2
The other end 12 is a free end that is fixed to the inside. However, the guide 1 does not come off the crane 2.
It fits in 3 and is restrained so that it can slide.

That is, when the eyeglasses are put on, the curved leaf spring 10 comes into contact with the face portion of the face and is pressed toward the crane 2, but in this case, the free end is guided by the guide 13.
It can slide to the front side along with, and an appropriate pressing force acts on the mechanical mechanism. Here, the attaching means and the attaching form of the curved leaf spring 10 are not limited, and the inside of the temple is not necessarily fixed.

That is, the pressure is moderate without causing pain to the mechanical parts, but without slipping. In order to prevent slippage, the leaf spring 10 is covered with a silicone resin layer. Of course, it is not limited to silicone resin. Therefore, in the case of this vine 2 as well, by wearing glasses, the modern 7 is locked to the ear and hits the back of the head, and one of the curved leaf springs 10 hits the komememi part, and one of the vines 2 is
The contact can be point contact (four-point contact for the entire glasses) or a contact area from the deformed leaf spring 10 to the modern 7, so that the glasses can be stably worn without the nose pad on the front part 1.

FIG. 3 shows a case where a part of the temple of FIG. 2 is changed, and the guide 14 is formed on the hinge 3. That is, the hinge 3 is elongated to form the guide portion. The free end of the curved leaf spring 10 is fitted in the guide 14.
As in the case of the above-mentioned embodiment, if the free end is deformed by wearing glasses, it slides to the front portion side and exerts an appropriate pressing force on the contact mechanism portion.

FIG. 4 is an embodiment showing a crane of the present invention. The temple 2 is provided with a contact portion 15 in which the temple itself is curved and deformed inward. When the eyeglasses are worn, the curved abutting portion 15 can be stably supported by hitting the face of the face. However, not only the hitting portion 15 which is curved inwardly hits the mechanical mechanism, but also the area L from the corresponding fitting portion 15 to the modern 7 is elastic and can fit to the face.
An anti-slip layer such as silicon is formed on the inner surface of the curved contact portion 15.

FIG. 5 shows a case in which the contact portion 16 is attached to the inside of the temple 2, and the contact portion 16 can hit the face of the face. The contact portion 16 has a smooth convex curved surface 17 and is made of a material having excellent elastic deformation such as silicon resin or rubber, and is deformed so as not to cause pain when hitting a face mechanical portion. You can Then, the corresponding portion 16 can have an attachment structure that can be replaced.

FIG. 6 is also an embodiment showing the vine of the present invention.
The temple 2 is provided with a hitting portion 18 which is biased by a spring force, and a pad 19 made of silicone resin or the like is attached to the tip of the corresponding hanging portion 18, and when putting on glasses, the pad 19 is a mechanical mechanism. You will hit the part. The pad 19 compresses the coil spring 20 and retracts, so that an appropriate pressing force acts on the mechanical mechanism portion.

As described above, the vine of the present invention is provided with the contact portion which is deformed by the pressing force inside, and the following effects can be obtained.

[0027]

The temple of the spectacle frame of the present invention is provided with an elastically deformable contact portion inside, and when the spectacle is put on, the corresponding portion will come into contact with the face of the face. Although there are various forms of the contact part, the modern part at the tip of the vine engages with the ear and abuts on the occipital region while having a corresponding bulge in the middle part of the vine and hitting the mechanical mechanism. That is, at least one of the vines has a two-point supporting structure, so that it is possible to wear glasses without providing a nose pad on the front portion.

The spectacles worn do not shift in position and, of course, do not come off. Since the front part does not shift in position, there is no shift in the viewpoint and it is easy to see, and there is little eye strain. Without the nose pad, the nose does not leave a red discoloration mark and the makeup does not peel off even if the glasses are worn for a long time.
