Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a butt mounting box leg for attaching a bat to a frame of eyeglasses and a manufacturing method thereof.

Conventional bat mounting is done by separately machining the foot part 1 and the phase part 2, which has a screw hole 3 and a screw insertion hole 4 in both side walls, as shown in Figures 1 and 2. The foot part 1 was fixedly attached to the phase part 2 by brazing 5. Therefore, there were some drawbacks as listed below.

(1) As the leg portion 1 and the phase portion 2 are brazed, the phase portion 2 is heated, and the threaded portion of the screw hole 3 becomes soft, resulting in poor or frequent threading of the screw.

(2) Since the leg portion 1 and the companion portion 2 are brazed, this work is difficult and increases the cost.

(3)? According to ii+(2), the box feet were either automatically manufactured or made unnecessary.

In view of the above-mentioned drawbacks of the conventional art, the present invention has been developed to improve the method of attaching screws to the case foot and its base. To obtain the manufacturing method.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 3 to 23.

In the embodiments shown in FIGS. 3 to 8, reference numeral 11 denotes a support portion for supporting a bat (not shown) which has only one side or an opening 12, and approximately at the center of one side wall 11a of this support portion 11 has an opening 12. A thick wall portion 13 is formed, and a screw hole 14 is formed in the thick wall portion 13. Further, a screw insertion hole 15 is formed in the side wall surface 11'b facing the screw hole 14. 16
is a foot portion whose tip end is attached to the frame of the eyeglass which is integrally molded with the upper wall surface 11C of the phase portion 11.

When attaching the butt to the glasses with the above configuration, since the phase part 11 and the foot part 16 of the box foot 10 are integrally molded, it may be necessary to process the box 1 (1; and the foot part) as in the conventional case. (Sufficient strength can be obtained.Also, attach a bat (not shown) to the part]
1, the screw 17 can also be screwed into the threaded hole 14 formed in the thick wall portion 13, so that defects in tightening the screw can be efficiently prevented.

Next, different embodiments of the present invention shown in FIGS. 9 to 18 will be described. In addition, in 89) 1 of these embodiments, the same parts as in the embodiments of the present invention are given the same numbers, and redundant explanation will be omitted.

The embodiments shown in FIGS. 9 to 13 are mainly different from the embodiments of the present invention described in 7i1].
a, an engagement protrusion 18 integrally molded on the inner wall surface of the recessed center of Ilb.
18 is formed and the butt is attached to the box foot 10A, and the foot portion 20 of the pad 19 supported by the companion portion 11.
20, an engaging portion 2 that engages with the engaging protrusion 18.18;
2J, this configuration allows the engaging protrusion 18.18 and the engaging portion 21.2 to engage by pushing the foot portion 20.20 of the pad 19 into the mating portion 11. The pad 19 can be easily attached to the companion part 11 by using the above-mentioned method.

The embodiments shown in FIGS. 14 to 16 are mainly different from the embodiments of the present invention described above.
By making the wall thickness of llb the same, the butt mounting does not require brazing even if the box foot 10B is constructed, so the screws can be sufficiently tightened.

17 and 18, the main difference from the embodiment of the present invention is that one side wall 11 of the phase portion 11
In this way, the bat can be attached to the box foot 1.a by forming a thick wall part 3 projecting inwardly on the part a, and forming a threaded hole 14 in the part. Even if a QC is configured, the same effects as in the above embodiment can be obtained.

Next, a method of manufacturing a box leg for attaching the butt of the glasses of the present invention will be explained using FIGS. 19 to 23.

The manufacturing method of the box foot 10B for attaching the butt of the eyeglasses shown in FIG. A step 27 is performed, leaving the foot parts 4', 1' 24, the box member 25, and the transfer metal plate 26, so that they can be processed into parts and parts, and a part 4A made by this punching process 27.
It consists of a step forming step 28 in which the legs 25 are narrowed down and formed into a box-like shape with only one side opened [1], and a cutting step 29 in which the foot portion 24 is cut off from the transfer metal plate 26, and the step 29 is the beginning of the transfer step 23. In this embodiment, ladle holes 30 are formed at a predetermined pitch interval approximately in the center of the metal plate 22, so that the metal plate 22 can be sequentially transferred at a predetermined pitch interval. In addition, in the punching step 27, after performing a square hollowing step 31 so as to form the foot part 2.1 and the transfer metal plate 26,
+iii Note: A border cutting step 32 is performed in which the box member 25 is formed by cutting the edges of the outer portion that is integrated with the foot portion 211. In addition, this center cutting process 31 and edge cutting process 32
You may do both at the same time. In addition, in the curved box part forming step 28, there is a flattening step 33 in which the box member 25 is flattened, a edging step 34 in which the flattened phase portion M25A is hemmed, and the edged part is embossed into a box shape. Narrowing down process 3
It consists of 5. Incidentally, screw holes may be formed in both side walls of the phase portion 11 at the final stage of the phase portion forming step 28.
Alternatively, the screw holes may be formed after the box foot 10B is separated from the transfer metal plate 26. Alternatively, a screw hole forming step may be inserted between the flattening step 33 and the embossed step 35.

The main difference between the method of manufacturing the box leg 10A for attaching the butt of glasses shown in FIG. 20 and the embodiment shown in FIG. Similar effects can be obtained in this case in that the engaging projections 18, 18 are formed approximately at the center of the wall surface.

In the method for manufacturing the eyeglass butt mounting 10 shown in FIG. 21, the main difference from the embodiment shown in FIG. This is because the thick portion 13 is formed in the . Note that the edging process 34
A screw insertion hole may be formed in a portion that becomes one side wall surface of the companion part.

In the manufacturing method of the eyeglass butt attachment 10C shown in FIG. 22, the main difference from the embodiment shown in FIG. This is because the thick portion 13 is formed in the . Incidentally, in the edging step 34, a screw insertion hole may be formed in a portion that becomes one side wall surface of the companion part.

The main difference between the attachment of the eyeglass butt shown in FIG. 23 and the embodiment shown in FIG.
Since the screw insertion hole 15 and the screw hole 14 are formed in the central part of i', post-processing is facilitated by forming the parts A and '' in this way.

As is clear from the explanation above, the present invention has the effect of forming the next column h<:.

(1) Since the phase part and the foot part are integrally molded, there is no need for adding a row as in the past, and addition is easy.

(2) Since the box and foot parts do not need to be brazed as in conventional methods, the threads of the threaded part formed on the side wall of the mating part will not become soft due to heating. Poor attachment can be efficiently prevented.

(3) Since there is no need for brazing processing, automatic manufacturing is possible, and manufacturing time and manufacturing costs can be reduced.

(4) Since the phase portion and the foot portion are integrally molded, it is possible to efficiently prevent the phase portion and the foot portion from coming off when adjusting the bat.

(5) Since the phase part and the foot part are integrally molded to eliminate the need for brazing, the heat of the brazing process does not cause the weld to dull, and sufficient strength can be maintained.

(6) Since a thick portion can be easily formed on one side wall of the chain portion, the butt mounting screw can be reliably screwed and fixed to the companion portion.

(7) The phase part and the foot part can be integrally formed by press assembly operations such as punching, flattening, and squeezing, making processing operations relatively easy.
