Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fastener for a bag-like skin body used to cover and attach an automobile seat, head rest, etc. (hereinafter referred to as an automobile seat, etc.). This type of fastener is used for terminal processing to close the top opening 1a of the bag-like skin body 1 of a seat back, as shown in FIG. It is used to close the section 2a and has a structure as shown in FIG. That is, the known fastener B shown in FIG.
A narrow band-shaped back plate portion 20 with a large length dimension a and a clamping plate portion 21 parallel to one side thereof are formed into the same body, and a fitting groove 23 into which a male mold 22 can be fitted is provided at parallel intervals. The male mold 22 with the skin material 14 of the bag-shaped skin body 1 sewn thereon is forcibly fitted into this narrow fitting groove 23.
In addition, a part of the male mold 22 is held and fixed to the locking portion in the fitting groove 23. However, since the fastener B having the above-described structure is molded from a hard synthetic resin material in order to prevent accidental detachment, it is difficult to suture the female and male molds 19 and 22 and the skin materials 13 and 14, and cracks may occur. In addition, due to its rigidity, it is difficult to insert, and a special tool is always required, which causes a decrease in work efficiency. Therefore, in view of the above points, the present invention aims to improve work efficiency by providing a fastener that can easily process the end of a bag-like skin body without the need for special tools, and that is easy to fit and difficult to separate. The purpose is to

Hereinafter, the drawings showing the embodiments of the present invention will be described. Fig. 1 is a perspective view of an automobile seat of bag-like skin bodies 1 and 2 when used as a seat bag and a headrest, and Fig. 2 is a perspective view of an automobile seat according to the present invention.

Fig. 3 is a partially enlarged vertical sectional view of the skin material sewn to the sewn part, and Fig. 3 shows the conventionally known fastener B.
FIG.

The fastener A is a combination of a female mold 3 and a male mold 4, and is used to close the openings 1a and 2a of the bag-like skin bodies 1 and 2 that form the skin of seatbacks and headless straws. The opening 1a is located on the top surface of the headless straw side of the bag-like skin body 1 of the seat backfish, and
In this case, it is provided on the bottom surface. The female mold 3 is made of a hard synthetic resin material, such as hard PVC, and has a narrow plate-like portion 5 having a length larger than the top opening 1a of the bag-like skin body 1.
A sewn portion 5a is provided on the upper edge of the plate-like portion, and a protruding strip 7 is provided on the lower edge of the plate-like portion, and a protruding strip 7 is integrally protruded from the opposite surface 6 side, and a sewn portion 5a is provided on the lower edge of the plate-like portion. A plurality of fitting recesses 8 having side channel type openings are provided at intervals of . The opening 8a of the fitting recess 8 is narrower than the inside and provided with a locking edge 8b.

The male mold 4 is made of a soft synthetic resin material, such as soft PVC,
Forming a narrow plate-like portion 9 with approximately the same dimensions as the female mold 3;
A sewn portion 9a is provided on the upper edge of the plate-shaped portion 9, and a plurality of spherical protrusions 11 are protruded from the lower edge of the plate portion 9 on the opposite surface 10 side corresponding to the fitting recesses 8, and the spherical protrusions 11... The locking flange 12 protrudes below, above, or both above and below toward the same facing surface 10 side. The female mold 3 and the male mold 4 have opposing surfaces 6 and 10 facing each other, and the spherical convex portion 11 of the male mold 4 is inserted into the fitting recess 8 of the female mold 3 by an external pressing force acting in the joining direction. ...Forcibly push in and fix it,
In addition, the locking collar 12 is joined to the upper or lower surface of the convex strip 7 to hold it in a parallel state. Female, male type 3, 4

form.

The skin materials 13 and 14 of the bag-like skin body 1 are integrated with a leather surface 17 on the front surface and a lining 18 on the back surface with the skin 16 at the center, and the terminal portion 13a of the skin material 13 is The leather surface 17 is sewn to match the facing surface 6 of the female mold 3, and the skin material 1 is sewn in the same manner.
The terminal portion 14a of the male mold 4 has the lining 18 on the opposing surface 1 of the male mold 4.
Sew and fix according to 0. And Fuasner A
As is known, the bag-like skin body 1 is turned over so that the lining 18 is exposed on the surface, and then the female mold 3 is
The facing surface 6 of the male die 4 is made to stand up so as to face the facing surface 10 of the male die 4, and the spherical convex portion 11 is formed as described above.
. . . and the fitting recess 8 .

As described above, the present invention has a convex strip 7 that protrudes on one side of the facing surfaces 6, 10 of the narrow plate-like parts 5, 9 of the female and male molds 3, 4 facing parallel to each other so as to create an opposing interval.
Since a fitting recess 8 is provided on one side and a spherical protrusion 11 is provided on the other side, pressing force from the outside is applied in the joining direction of the opposing surfaces 6 and 10, which is extremely easy and does not require any special tools. Moreover, the female mold 3 can maintain the strength and shape of the mating part depending on the material and maintain a robust mating state, while the male mold 4 also makes full use of the characteristics that make it easy to fit depending on the material. This can further improve work efficiency, and the locking part 1
2 acts as a wall in the direction of peeling, thereby preventing accidental separation. Furthermore, a skin material 1 is placed in the receiving space.
Since the terminal parts 13a and 14a of 3 and 14 are simply housed together, there is no hindrance to terminal processing and the work can be done more easily.
