Description

[Detailed Description of the Invention] The present invention relates to improvements in front and lining fabrics, loop-shaped ends of handles, and holders for connecting two or more members in bags, etc., such as fabrics and handles.

Conventionally, washers have been widely used as receiving fittings for joining these types of members. For example, when polymerizing and fixing the outer fabric and lining fabric of a bag, hollow studs are passed through from the outer fabric side to the lining fabric side, and the protruding tips of the hollow studs are attached to the washer that has been placed on the lining fabric side in advance. The hollow stud was inserted into the hole and expanded, and the expanded portion was engaged with the edge of the hole of the washer, and the two pieces of fabric were clamped and joined by the head of the hollow stud and the washer. However, when using this washer, the lattice-like expanded portion of the hollow stud is exposed, which not only makes it look extremely unsightly, but also sometimes the expanded portion does not engage tightly with the edge of the hole of the washer and floats up. Not only can they stumble or break, causing injuries to fingers and fingers, but there are also problems with the strength of the bond.

Therefore, in place of the above-mentioned washer, a flat container-shaped (cap-shaped) receiving metal fitting has recently been used. When using this bracket to connect two or more members with a rivet, such as a hollow rivet, the inner surface of the bracket should be brought into contact with the hole drilled in the member in advance for the insertion of the shaft of the hollow rivet. After that, by lowering the hollow stud from above the member at high speed, the tip of the shaft of the hollow stud is expanded and tightened within the inner surface of the receiver, and the head of the hollow stud and the receiver are tightly attached. It connects two or more parts.

However, when using the above-mentioned conventional holder, it is not only extremely difficult to align the hole of the member with the inner surface of the holder, but if they do not match completely, the hollow rivet will be damaged when the hollow rivet is hit. If the tip of the shaft comes into contact with a part of the periphery of the hole of the member, it may bite and polymerize part of the material around the hole, or the hollow stud may be inclined and not pass vertically into the inner surface of the receiving metal fitting. It is not possible to reliably expand the tip of the shank of the rivet, and this tendency becomes even more pronounced when the member is filled with reinforcing plates such as iron plates, synthetic resin plates, or fillers such as sponge or elastic materials such as urethane. There are problems in that it is easy to occur and it is difficult to join the members together.

Furthermore, when using the above-mentioned washers or conventional metal holders, the head of the rivet can only be used on the outer fabric side,
There is a problem in that the design of bags has to be standardized.

The present invention was created in view of this, and it is possible to reliably and firmly connect two or more members without exposing the expanded or crushed portion of the rivet, and also allows for the desired pattern, initials, etc. to be printed on the body of the holder. The second method for use in bags, etc. is to select and fit the obturators that have been applied, so that the receiving metal fittings can be applied to the front side of the bag, and furthermore, the positioning of the members is made easy and the studs can be attached accurately. The object of the present invention is to provide the above-mentioned member coupling receiving fitting.

That is, the present invention has a main body that is flat and hollow, with a recess with a small hole in the center on the upper surface and a hole for fitting the tip of the rivet shaft on the lower surface, and a recess in the main body. This device is characterized by comprising a short shaft portion integrally provided at the center of the lower surface of the head so as to fit into the small hole and into the small hole.

Embodiments of the present invention will be described below based on the drawings.

In the figure, A is a receiving metal fitting, and this receiving metal fitting A consists of a flat hollow main body 1 and a substantially rivet-shaped obturator 2. The main body 1 is made of a material such as metal or non-ferrous metal, and has a depression 11 in the shape of a mortar or inverted truncated pyramid on its upper surface, and the depression 11 is shaped like an inverted truncated pyramid.
A small hole 12 is bored in the center of the bottom of the rivet, and a hole 13 for fitting the tip of the shank, which has approximately the same diameter as the shank of the stud to be applied, is provided in the lower surface.

The obturator 2 has a head 21 and a short shaft 22 integrally molded from metal, non-ferrous metal, synthetic resin, rubber, etc. The head 21 has a cross-sectional shape that fits into the recess 11 of the main body. A marking 3 such as a required pattern, initial mark, etc. is applied to the upper surface. Further, the short shaft portion 22 projects downward from the small hole 12 of the recess 11 and has a length and diameter sufficient for tight fitting.

By the way, B is a hollow stud applied to the bracket A.
The tip of the shaft or the entire shaft is tubular.

Next, FIG. 4 shows different embodiments of the obturator,
Figure A shows an obturator 2 in which a large number of protrusions in an annular, helical or satin-like shape are carved on the circumferential surface of the short shaft part 22 to provide an engaging part 4, and Figure B shows the short shaft part 22 of the obturator 2. The engagement part 4 is formed by bulging out the tip part in a substantially umbrella shape, and in the figure C, the engagement part 4 is provided by protruding a plurality of locking claws on the peripheral surface of the end of the short shaft part 22. In the same figure, D is the short shaft part 2.
The distal end of the obturator 2 is split in the shape of a tip, and a claw is formed to prevent the obturator from coming off.
It fits more tightly and firmly into the recess 11 of. Although not shown in the drawings, the short shaft of the obturator is made hollow, and a through hole is provided in a direction perpendicular to the short axis at a required position at the end (a position protruding from the small hole 12).
It is also possible to crush and fix the tip from this through hole.

Therefore, using the receiving metal fitting according to the present invention, the outer fabric
The case where the and lining fabric Y are combined will be explained. The main body 1 of the holder is placed on the upper surface of the cradle of a fastener driver, which has a built-in spring and a guide rod that can freely come out and retract from the upper surface, by inserting the guide rod into the small holes 12 and 13 of the main body 1. After placing the holes in the outer fabric When the held hollow stud B is lowered at a high speed, the tip of the shaft of the hollow stud B comes into contact with the tip of the guide rod and falls vertically against the spring force of the guide rod until it reaches a predetermined position. When this happens, the holding of the hollow stud is released, and the head of the hollow stud is struck by the striking part, and the tip of the shaft is expanded by the outer circumferential surface of the recess 11 of the main body 1, and this expanded portion is formed between the hollow inner walls of the main body 1, and both the fabrics X and Y are completely polymerized and fixed by the hollow studs B and the main body 1. after that,
When the obturator 2 bearing the arbitrary mark 3 is pushed or folded into the recess 11 of the main body 1, the end of the short shaft portion 22 of the obturator protrudes from the small hole 12 and is firmly fitted. The recess 11 in the body is sealed by an obturator.

Incidentally, in the above-described embodiment, hollow studs were used as the studs applied to the receiving metal fitting, but it is also possible to use lances, pit tacks, etc.

Therefore, when using the metal holder according to the present invention, it is easy to select the obturator according to the type of bag, with the body of the metal holder having the same or a different color, and optionally with a desired marking on the head. And since it can be installed securely, the bracket can be applied to the front side of the bag.
It is extremely effective in terms of design, and furthermore, the hole in the component and the hole in the bracket can be easily matched, and two or more components can be accurately and firmly joined with rivets without biting, and this rivet work It also has the advantage of being safe.
