[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sheet plate obtained by cutting out parts constituting glasses such as a front frame and a vine.
[0002]
[Prior art]
FIG. 5 shows a general spectacle frame. The spectacle frame is attached to both sides of the front frame (A) so that the cranes (B) and (B) can be folded, and the front frame (A) is attached to both rims. (C) and (C) are connected by a connecting member (D), and outer parts (E) and (E) are brazed to the outside of the rims (C) and (C). The crane (b) is connected to the armor (e) via a hinge (f), and has nasal pads (g) and (g) inside the rim (c) and (c).
[0003]
The eyeglass frame shown in the figure is only a basic form, and is actually decorated with secondary processing to form a highly fashionable object. By the way, in order to manufacture the rim (c) of the above-mentioned eyeglass frame, the groove wire is processed into a thin wire rod and bent into a predetermined shape, and the rim (c) It is brazed with a connecting member formed into a shape. The armor (e) is also bent and brazed to the correct position outside the rim.
[0004]
In order to attach and detach the lens to and from the rim (c), a broach is provided on the outside, and for this purpose, it is brazed to the outside of the rim. In addition, legs for attaching the nose pads (g) and (g) must be provided, and a hinge (f) is required so that the crane (b) can be folded. Thus, in order to manufacture a conventional spectacle frame, each individual part must be processed into a predetermined shape, and then each part must be assembled by brazing. Therefore, a very large number of man-hours are required to manufacture the spectacle frame, and the spectacle frame is expensive.
[0005]
[Problems to be solved by the invention]
As described above, the conventional eyeglass frame has the above-described problems in its production. The problem to be solved by the present invention is this problem, and provides an eyeglass parts cut-out sheet plate that can be manufactured very easily and at low cost.
[0006]
[Means for solving the problems]
The parts constituting the glasses are manufactured through a process such as punching one flat sheet without forming individual wires as in the prior art. Moreover, it is assumed that the spectacle parts are accommodated in a sheet plate having a predetermined size. The sheet plate is punched and a part of the sheet plate is connected to the sheet plate main body so that the punched parts are not detached from the sheet plate. Then, if necessary, the parts of the sheet plates can be cut to take out the parts, and the taken out parts can be assembled into a predetermined spectacle frame.
[0007]
By the way, although the kind of components accommodated in a sheet | seat board is not limited, For example, a front part and two vines are stamped. Separately manufactured parts may be used for the joint that foldably attaches the vine to the nose pad and the front part. In the case where the sheet plate is thin and has a constant thickness, it is more suitable to use separately manufactured parts that require a three-dimensional shape. However, if the sheet plate is injection-molded, the part can be molded by partially increasing the thickness. Here, the eyeglass parts are not limited to being stamped by a press, but can be injection-molded or cut. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0008]
【Example】
FIG. 1 is an embodiment showing a glasses part cut-out sheet according to the present invention. The sheet plate shown in the figure is formed by cutting out a front portion 1 and two temples 2 and 2. The front portion 1 has rims 3 and 3 into which lenses are fitted and a connecting portion 4 that connects the rims 3 and 3, and a broach 5 is provided outside the rim 3 so that the cut of the rim 3 can be opened.
[0009]
A leg 6 for attaching a nose pad is extended inside the rim 3 and has a C-shaped fastening portion 7 at the tip. One temple 2 has a thin tip and extends straight, and two thin and short legs 8a and 8b are provided in parallel at the base.
[0010]
By the way, the front part 1 and the two cranes 2 and 2 are cut out in one sheet plate, but the front part 1 has joints 10a and 10b for connecting the broach 5 on one side to the sheet plate body 9. are doing. Similarly, the vine 2 is connected to the sheet plate main body 9 through a thinner connection 11 from the tip.
[0011]
Therefore, the front portion 1 can be separated from the sheet plate body 9 by cutting the joints 10 a and 10 b, and the temple 2 can be separated from the sheet plate body 9 by cutting the joint 11. The joints 10a, 10b and the joint 11 can be cut using a suitable tool, and the cut surface is polished later so as not to be square.
[0012]
FIG. 2 shows an eyeglass frame assembled by cutting off the front portion 1 and the temples 2 and 2 from the sheet plate. When assembling this spectacle frame, the nose pad 12 manufactured separately is attached to the fastening portion 7 at the tip of the leg, and the armor 13 and the modern 14 are also separately manufactured and assembled.
[0013]
The nose pad 12 can be attached by protruding a fastening piece on the back side of the nose pad 12 and fitting it into the C-type fastening part 7. The modern 14 has a tip of the temple inserted into the insertion hole formed in the central axis thereof. After mounting, the tip of the vine is bent into an approximate L shape. Further, the armor 13 has a block shape and is attached to two broach pieces 15a and 15b constituting the broach 5 of the front portion 1.
[0014]
The outer side of the rim 3 is opened, and the broach pieces 15a and 15b are formed to extend outward at the tip of the rim line. Then, the lens is fitted to the rim 3 and the armor 13 is attached to the broach pieces 15a and 15b. FIG. 3 shows a state before the broach 5, the armor 13 and the temple 2 are assembled. The holes 21 and 21 (see FIG. 4) provided inside the armor 13 are fitted with the broach pieces 15a and 15b so that the armor 13 is Mounted. Strict tolerances are provided so that the broach pieces 15a and 15b do not come off simply by fitting into the holes 21 and 21, and an adhesive can be used if necessary.
[0015]
A temple is attached to the armor 13 attached to the broach 5 so that the temple 2 can be folded. An L-shaped step is provided on the upper surface of the alloy, and a stopper 17 that is substantially parallel to the outer surface 16 is formed. As shown in FIG. 4, the upper surface of the armor is provided with a shaft hole 19 at the corner of the lower surface 18 and an arc groove 20 on a predetermined radius centered on the shaft hole 19.
[0016]
Therefore, the leg 8 a provided on the temple 2 is fitted in the shaft hole 19, and one leg 8 b is fitted in the arc groove 20. Therefore, the leg 8 b fitted in the arc groove 20 can move along the arc groove 20, and for this purpose, the temple 2 is pivoted and folded around the leg 8 a fitted in the shaft hole 19. When the temple 2 is opened, the temple 2 hits the stopper 17 and the degree of opening is restricted.
[0017]
Here, the material of the sheet plate shown in FIG. 1 is not limited, and can generally be a resin sheet plate or a metal plate. In the case of a metal plate, press punching is performed to cut out the front portion 1 and the vines 2 and 2. Then, barrel polishing is performed to remove burrs and burrs on the punched surface. On the other hand, when the resin plate is used, the front portion 1 and the vines 2 and 2 can be formed in a cut-out state by injection molding. If injection molding is performed, the sheet plate is not constant in thickness, and it is also possible to simultaneously mold a thick armor 13 or a curved nose pad 12.
[0018]
By the way, although the front part 1 is integrated in the said Example, both rim | limbs 3 and 3 and the connection part 4 can also be cut out to a sheet | seat board as another components, respectively. Further, the form of the broach 5 for attaching the armor 13 and preventing the lens fitted on the rim from being removed is not limited. And the folding structure of the vine attached to an armor is not restricted to the case of an Example.
