Description

[Detailed description of the invention] The present invention consists of a male or female fitting body placed on one side of a predetermined hook attachment base material such as cloth or a resin sheet, and a fastening body placed on the other side. A plurality of fixing needles located on the same circumference are protrudingly provided on the male or female mating body,
It relates to a hook that has a small hole for inserting the needle at a position on the same circumference.

In this type of hook, the male or female fitting body and the fastening body, which are arranged opposite to each other on both sides of the hook mounting base material, are integrated by inserting the needle into the small hole. Since there are multiple holes, even if the axes of the male or female mating body and the fastening body match, if the positional relationship around the axis is misaligned, the needle may not be inserted into the small hole. It has the disadvantage that it cannot be used and the needle may break.

In other words, this type of hook is normally attached to fabrics, resin sheets, etc. automatically by a hook attaching machine, but if the male or mating body and the fastening body are out of phase, it may be difficult to bring them close together. Since the needle breaks when moved, a highly reliable and high-precision positioning device is required to align the two. This makes it difficult to automate the installation of this type of hook. It has become a bottleneck.

The present invention provides a hook that can solve these problems.

An embodiment of the present invention will be described based on the drawings. 1A has a fitting convex part a in the center, and around it a plurality of small holes 1a located on the same circumference. The male fitting body 1B has a fitting recess in the center, and around it a plurality of small holes 1b located on the same circumference.
The female fitting bodies 2A and 2B have the small holes 1a...
..., 1 b... It is an annular fastening body having a plurality of sharp fastening needles 2a..., 2b......, which are inserted into the I A , I B , 2 A,
2B is a needle 2a made of a synthetic resin material and pierced through a predetermined hook attachment base material 3 such as cloth or a resin sheet.

By hitting with an annular hammer (not shown) inserted into... and expanding the diameter, the small hole 1a...,

In such a hook, in the present invention, the male and female mating bodies IA, IB have small holes (Lla,

Needles 2a..., 2b... provided on A, 2B
(In this embodiment, the number of needles is 6 and the number of small holes is 6×2, but the number is not limited to this.)

For example, the former is 5, the latter is 5X2, 5X3, the former is 6, the latter is 6×2゜6×3, the former is 7, the latter is 7X2, 7X3
If the latter is a multiple of the former (an integer multiple of 2 or more), it can be set arbitrarily.

). Sl and S2 in the figure are small holes 1
A slope for guiding the needle tip is inclined so that the part b is a valley and the intermediate position between the small holes 1b is a peak.

The illustrated slope S1. S2 is recessed so that the peak is flush with the back surface of the female mating body 1B, but a raised part that protrudes from the back surface of the female mating body 1B is provided, and this raised part has a slope S.
1. S2 may also be formed.

According to the above configuration, the number of small holes 1b is set to be an integral multiple of 2 or more of the number of needles 2b. Small hole 1b compared to the pitch
Since the pitch of ... is small, it is easy to match the needle 2b ... and the small hole 1b ..., and the female fitting body 1B
Needle 2b

In particular, between the small holes 1b..., the slope S1. S2...
. . . is a shape, even if the positions of the tip of the needle 2b and the small hole 1b deviate in the circumferential direction, this slope S1. Needle 2b... by S2
The tip is guided to the small hole 1b.

Therefore, the device for controlling the phase alignment between the male and female fitting bodies IA, IB and the fastening bodies 2A, 2B can be omitted, making it possible to manufacture the hook attachment machine easily and at low cost.

Incidentally, the male mating body 1A and the mating body 1B differ only in the convex part a and the concave part A, and the other structures are the same, so detailed illustrations and explanations of the male mating body 1A are omitted. .

Further, the fastening bodies 2A and 2B have the same structure and the same dimensions,
It is shared by both male and female mating bodies IA and IB.

As described above, according to the present invention, the fixing body is provided with a plurality of fixing needles located at equal intervals on the same circumference, while the male or female mating body is provided with a plurality of fixing needles located at equal intervals on the same circumference. In addition, since the small holes for inserting the needles are provided at equal intervals in numbers that are an integral multiple of 2 or more of the number of needles, the pitch of the small holes is small compared to the needle pitch, making it easy to match the needles and the small holes. This has the effect of suppressing breakage of the needle due to misalignment between the male or female mating body and the fixing body.
