As a tip metal fitting for a slide loop for a suspender, one having a shape as described in US Pat. No. 4,935,997 is known, and FIG. 8 shows a metal fitting 10 as a typical example thereof. Is exemplified. The metal fitting 10 has a central portion 12 that becomes a bottom surface during assembly, and side portions 14 and 14 that are connected to each side along the longitudinal direction of the central portion 12 via a bending line. At the time of the latching operation on the other member, both end portions 18 and 18 of the wire member 16 are held in a state where they can be slightly slid along the central portion 12. Inwardly projecting portions 17 and 17 are formed in a part of the loop of the wire member 16, and when forcing the loop, for example, the neck portion of the button member 26 between the portions 17 and 17, The space between these portions 17 and 17 is expanded against the elasticity of the wire member 16, and then returned to the original position so as to be hooked on the button member. At this time, the both end portions 18 and 18 slide inside the metal fitting 10 as described above.
When the bracket 10 is attached to the wire member 16, as shown in a stepwise manner in FIG. 9, first, the side portions 14 are slightly rotated in the direction of approaching each other along the longitudinal direction of the central portion 12. 9, the wire member 16 is brought closer to the metal fitting from the outer surface 20 side of the central portion 12, and the wire member 16 is passed through one side portion of the metal fitting 10 so that both end portions 18 are connected to the end portions 18. After protruding forward from the side portion 14, it is brought into a state of being aligned horizontally with the inner surface 24 of the central portion 12 of the metal fitting 10, and then the wire member 16 is retracted toward the inner surface 24 of the central portion 12. The base portions 22 of the both end portions 18 are brought into contact with the inner surface 24. Then, in this state, the side portions 14 are further rotated in the directions approaching each other, and the metal fitting 10 is caulked to obtain the state of FIG.
However, since it is necessary to move the wire member in three directions as described above before the wire member 16 is disposed inside the metal fitting 10, it is difficult to automate the series of operations until the metal fitting 10 is caulked. It is. Therefore, at present, this must be done manually, and the working efficiency is extremely poor. Therefore, the above-mentioned work is not only low in productivity but also increases the cost of parts.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail with reference to FIGS. 1 to 6. FIG. 1 shows a perspective view of a metal fitting 50 according to one aspect of the invention, and FIG. 2 shows an exploded view of the metal fitting 50. As shown in detail in FIG. 2, the metal fitting 50 has a central portion 60 at a position opposite to the conventional example shown in FIGS. 8 and 9, and on each side of the central portion 60 in the longitudinal direction of the central portion 60. A pair of side portions 70 and 80 are connected to each other via folding lines 62 and 64 formed along the lines.
These side portions 70 and 80 are lateral in the present embodiment for the purpose of assembling the fittings in which folded pieces described later are overlapped in order to loosely fit the wire member 16 inside the fitting 50. The length L ₁ of the portion 70 is slightly longer than the length L ₂ of the side portion 80. Preferably, each of the side portions 70 and 80 is formed with semicircular cutouts 72 and 82 as shown, for receiving the neck portion of the button member. Thus, the button member is stably fixed. By providing the semicircular cutouts 72 and 82, in this embodiment, the side portions 70 and 80 are substantially U-shaped symmetrically arranged with the central portion 60 as the central axis. For this reason, both ends of the central portion 60 are in the form of projecting pieces 120, 140. On the other hand, each of the U-shaped side portions has folding pieces 90 and 100 for securing a space for inserting the wire member 16 into the metal fitting 50 inside the metal fitting 50 and holding the wire member 16. Are connected via folding lines 74 and 84, respectively.
[0006]
Referring to FIG. 3, the metal fitting 50 has folding pieces 90 and 100 on each side portion 70 and 80 on the same side of the side portions 70 and 80 along fold lines 74 and 84, respectively. The side portions 70 and 80 are bent at a right angle, and then each of the side portions 70 and 80 is slightly rotated in a direction approaching each other around the central portion 60. It is shown. The amount of rotation is set such that the distance a between the free end portions of the folding pieces 90 and 100 is sufficiently larger than the diameter of the wire member 16, thereby allowing the wire member 16 to be inserted between the free end portions. The Further, both ends of the central portion 60, that is, the protruding pieces 120 and 140 (see FIG. 4) are bent at a substantially right angle in a direction opposite to the bent pieces 90 and 100 and in a direction approaching each other. Is done. As a result, a space 180 through which both end portions 18 of the wire member 16 are inserted is created between the protruding pieces 120 and 140 on the inner surface 160 side of the central portion 60. The space 180 also has an effect of limiting the distance that both end portions 18 and 18 of the wire member slide.
[0007]
FIG. 4 is a plan view showing a state of insertion of the wire member 16 into the metal fitting 50 according to one aspect of the present invention, and FIG. 5 illustrates a case where the state of FIG. As best shown in FIG. 5, the wire member 16 is inserted between the side portions 70 and 80 only by approaching the metal fitting with the inner surface 160 of the central portion 60 facing both end portions 18. The Thus, in the prior art, the both end portions 18 of the wire member 16 are first approached from the outer surface side of the central portion, then lowered when they pass over the metal fitting, aligned with the inner surface of the central portion, and then retracted toward the inner surface. Compared with passing through these three stages, the path for inserting the wire member through the metal fitting is greatly shortened and the operation itself is simplified. This simplification of work enables automation of work that has been difficult in the past.
The wire member 16 is pre-formed with a shoulder portion 200 following the end portions 18 in the conventional manner, the shoulder portion 200 passes between the free ends of the folding pieces 90 and 100, and the end portions 18 are in the space. When the wire member is housed in 180, the approach of the wire member to the metal fitting is stopped, and then the metal fitting 50 is crimped to overlap the folded pieces 90 and 100 as shown in the lower part of FIG.
[0008]
6 and 7 illustrate a bracket 500 according to another aspect of the present invention. As shown in a development view of FIG. 6, the metal fitting 500 has a central portion 600 similar to that in the metal fitting 50 shown in FIG. 1 and bending lines 620 and 640 along the longitudinal direction of the central portion 600. It has a pair of side portions 700 and 800 connected to each side of the central portion 600. And these side parts 700 and 800 are also the side part 700 from the reason of the metal fitting assembly which overlaps the below-mentioned folding pieces in order to loosely fit the wire member 16 inside the metal fitting 500. It is slightly longer than the side portion 800. Each side portion 700 and 800 is formed with semicircular cutouts 720 and 820 for the same purpose as in the embodiment described with reference to FIGS. In the example, the side portions 700 and 800 are substantially U-shaped symmetrically arranged with the central portion 600 as the central axis.
Fold pieces 900 and 1000 for securing a space allowing insertion of the wire member 16 into the metal fitting 500 inside the metal fitting 500 are connected to the U-shapes via bending lines 740 and 840, respectively. ing.
[0009]
Further, in the embodiment shown in FIGS. 6 and 7, flap-shaped extension portions 1100 and 1150 are provided at opposite positions of each edge of each of the two side portions 700 and 800 with the central portion 600 interposed therebetween. Each is formed. These extension portions 1100 and 1150 connect the folds 900 and 1000 in each of the side portions 700 and 800 to the side portion 700 along the fold lines 740 and 840 on the same side of each side portion 700 and 800. And 800 at the same time or separately at the same time or separately on the same side as the folded pieces 900 and 1000. As a result, when the wire member 16 is inserted into the metal fitting 500 in the same manner as in the previous embodiment, and then the metal fitting 500 is crimped, the folded pieces 900 and 1000 face each other. A partial side surface 1300 as shown in FIG. 7 is created at each corner. By forming the partial side surface 1300, there is no sharp edge-like portion at each corner of the metal fitting 500, so that there is no possibility that a finger or a part of the body is damaged or damaged due to contact with the portion. In addition, the inner edges 1500 and 1700 of these side surfaces 1300 apply a large force to the end portions 1200 and 1400 in the longitudinal direction of the central portion 600 through both ends of the wire member 16, so that the end portions 1200 and 1400 When it is going to be pushed outward, it also exerts a reinforcing effect of contacting the end portions 1500 and 1700 to prevent further expansion.
