Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eyeglass frame provided with a high-tensile yarn such as a nylon yarn.

[0002]

2. Description of the Related Art Nyroll frames are known as one type of eyeglass frames. This nyrol frame is a frame that holds the lower half of the lens with water thread,
For example, it has a form as shown in FIG. The frame shown in the figure is only a basic form, and in fact it will be constructed with various designs, but the ends of the water thread (b) are fixed to both ends of the arc-shaped rim (a). And rim
The lens (c) is held by (a) and the water thread (b). The two rims (a) and (b) are connected by a bridge (d), and the outer rim is provided with a yoke (e) and (e) so that the vine can be folded through the hinges via hinges. It is connected to.

[0003] However, when the rim wire is thick to some extent, the bridge (d) can be directly brazed and the yoke (e) can be directly brazed, but a thin rim wire which can be fitted into the lens groove. In the case of (2), the bridge cannot be directly connected by the bridge (d), and the bridge must be brazed to the reinforcing piece after the reinforcing piece is once brazed to the tip of the rim. Similarly, when attaching the yoke, it is also performed through a reinforcing piece brazed to the end of the rim.

Accordingly, the leading end of the water thread is inserted into holes formed in reinforcing pieces brazed to both ends of the rim and fixed. In this way, a reinforcing piece must be brazed to the end of the rim, and further a bridge or a yoke must be brazed to the reinforcing piece.
Due to the heavy brazing structure, the cost is increased, and the heat at the time of brazing the reinforcing piece to the thin rim wire lowers the strength of the brazed portion and is often damaged. On the other hand, if the reinforcing piece is brazed to a frame using a thin rim wire, the appearance is impaired, and the effect of the Nyroll frame is reduced by half. In particular, the center of the frame where the bridge where the bending moment is greatest is located is often damaged, and the appearance of this portion is impaired.

[0005]

The nyroll frame using such a thin rim wire has the above-mentioned problems. The problem to be solved by the present invention is this problem, and even in the case of a thin rim wire, an external appearance in which a reinforcing piece is not brazed to the inner end of the rim and the bridge is not used as an independent part. Also provide a simple and good nylol frame.

[0006]

The nylol frame of the present invention is not a structure in which both arc-shaped rims are connected via a bridge, but a frame in which both rims and a bridge are integrally formed. A reinforcing piece is generally brazed to the outside of the rim so that a yoro is attached thereto, and a vine is connected to the yolo via a hinge so that the crane can be folded. A hole is penetrated through the tip of the reinforcing piece and the end of the bridge, and a high-tensile thread such as a water thread is inserted and fastened. However,
If the wire is relatively thick, or if a wire with very high strength is used, the yolo is directly brazed without the above-mentioned reinforcing piece and a hole at the end where a high-tensile thread is fixed is attached. In some cases, a holding portion is formed.

Here, the holes are provided at both ends of the bridge (boundary portions between the bridge and the rim), and the fastening portions are compressed and formed flat. The rim and the bridge may be formed of a wire having the same thickness, or the bridge may be formed of a thick wire. Of course, both rims and bridges are 1
This wire is formed by bending a wire, and a region to be a bridge is thickly swaged.

On the other hand, the nylol frame of the present invention is not limited to the case where the fixing means of the water thread is locked in the hole as in the prior art. It can also be locked. In addition to the case where the end of the water thread is directly locked to the key portion, the water thread end may be locked to the key portion via a locking tool formed with a key. In some cases, the frame is used as a front-hanging type frame. In this case, since it is not necessary to attach a lip and a crane, a reinforcing piece is not brazed, and a hook is provided on the rim. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 shows a case in which a lens is fitted to a nyroll frame according to the present invention. A front frame 1 has rims 2 and 2 having an arc shape and a bridge 3 between the rims 2 and 2. And the rims 2 and 2 and the bridge 3
It is manufactured by molding a wire rod. Reinforcing pieces 4 and 4 are brazed to the outer sides of the rims 2 and 2, and a reinforcement 5 is brazed to the reinforcing pieces 4. Of course, the vines are connected to the yoroi 5, 5 via hinges so as to be foldable.

By the way, a small hole penetrates the tip of the reinforcing piece 4, and small holes are also provided at both ends of the bridge 3 (boundary portion between the bridge 3 and the rim 2). The lens 7 is held between the rim 2 and the water thread 6 by being inserted and fixed at both ends thereof. FIG. 2 is an enlarged view of a boundary portion between the bridge 3 and the rim 2, and the fastening portion 9 is provided with small holes 8, 8 therethrough as shown in FIG. 2. However, the fastening portion 9 provided with the holes 8, 8 is compressed to be flat. That is, the fastening portion 9 is formed to provide the holes 8 in the thin rim wire.

When the rim 2 is made of a thin wire that can be completely fitted into the lens outer peripheral groove, the strength of a bridge made of a wire having the same thickness is low.
The bridge 3 can be made thicker as shown in FIG.
In (b), since the rim 2 is formed of a relatively thick wire, the bridge 3 is also formed of a wire having the same thickness. Here, the number of the holes 8 is not limited, but generally two holes 8 are provided so that the inserted water thread 6 does not come off.

If the rim wire is made thicker as shown in FIG. 2B, it will not fit into the lens outer peripheral groove. However, by chamfering the outer peripheral groove, a part of the rim wire is fitted and the lens is fitted. The width of the outer circumferential groove can be increased by making it possible to support and changing the material of the lens to make it hard to break. FIG. 2C shows another specific example of the bridge 3. The bridge 3 has a rectangular cross section formed by molding the entire wire. Further, (d) shows a substantially U-shaped reinforcing material 1 for reinforcing the bridge 3.
6 is brazed to form holes at both ends of the reinforcing member 16.

FIG. 3 shows another embodiment of the present invention, in which both nose pads 10 and 10 are attached to the tip of a generally U-shaped pad arm 11 and the pad arm 11 is soldered along the lower surface of the bridge 3. I have attached. Therefore, even if the bridge is made of a thin wire, the strength of the bridge 3 is increased by tying and brazing the pad arm 11, and the bridge 3 is not broken even if the bridge portion is not particularly thickened. When the pad arm 11 is attached, it is preferable to form a groove in the lower surface of the bridge 3 and braze the pad arm in a state where the pad arm is fitted in the groove.

FIG. 4 shows an embodiment of the present invention applied to a front-end frame. The front-mounted frame is used by hanging it on the front of ordinary glasses that are always worn. For example, sunglasses can be used as a lens of the front-mounted frame, and can be used by hanging the front of the glasses when necessary. That is, it is not necessary to separately prepare prescription sunglasses. Therefore, this front-hanging frame is the same as the nylol frame except that the nose pad and the crane are not attached. However, hooks 12, 12,... For hanging on the front of the glasses are provided.

FIG. 5 shows an embodiment in which the fixing form of the end of the water thread is different. A small key 13 is formed at the outer end of the rim, and a concave portion 14 is provided at the boundary between the bridge 3 and the rim 2 by bending a wire. Therefore, one end of the water thread 6 has the recess 1
4 and the other end is locked to a key 13 provided outside the rim. Here, it is preferable to provide a ring 15 at the tip as shown in (b) so that the water thread 6 can be locked to the recess 14 and the key 13.

FIG. 6 shows another embodiment for fixing the end of the water thread. A small key 13 is formed at the outer end of the rim, and a wire is bent at the boundary between the bridge 3 and the rim 2. The point of forming the concave portion 14 is the same as the case shown in FIG. However, the fastening mode shown in the figure uses the locking tools 16, 16 without directly locking the end of the water thread to the key 13 and the recess 14. As shown in FIG. 2B, the locking member 16 includes a key 17 and two holes 18, 1.
8 is a small plate on which 8 is formed.

The leading end of the water thread 6 is
Key 17 is a key 1 provided at the end of the rim.
3 and a recess 1 provided at the boundary between the bridge 3 and the rim 2
4 and locked. As described above, in the nylol frame of the present invention, both rims and bridges are formed by bending a single wire, and a water thread is fixed to the leading end of the rim and the bridge end to hold the lens. The following effects can be obtained.

[0018]

The nyroll frame of the present invention is formed by bending one wire to form both rims and a bridge.
The frame looks very simple and has a wide field of view. Since the rim is not brazed to both ends of the bridge where the bending moment acts most, the strength does not decrease due to the brazing heat, and the manufacturing cost is reduced. In particular, when a front-hanging frame is configured, a nose pad and a vine are not required, so that the frame is very light and easy to hang.
