Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a snap hook holder for holding a male hook in an automatic hook sewing machine.

<Prior art> The structure of the retainer used in attaching a conventional snap hook is described in Utility Application No. 110802/1982, which is a retainer that faces the inner wall of the retaining hole into which the papillary convex portion of the male hook is inserted. A spring material is attached by soldering, and the convex portion of the snap hook is inserted from below the holding hole so that the neck of the papillary convex portion is held elastically by the spring material.

<Problems to be solved by the invention> However, since the retainer in the above-mentioned conventional example is a closed type retaining hole into which a papillary convex portion is fitted, the snap hook must be inserted in one direction of the retaining hole. (from below), and it was impossible to insert from the side of the holding hole.

As a result, the holder cannot be attached unless it rises to the point where you can place your finger on the bottom of it. This may not be sufficient in some cases, impairing versatility.

In addition, with conventional holders, the spring material that holds the hook is soldered to the tip, which becomes dull due to the heat and loses its elasticity, making it difficult to obtain sufficient holding strength. However, within a short period of time, the hook cannot be held properly, and in some cases, the hook may rotate due to vibration or other factors, causing the needle hole to meet the needle out of alignment, causing the needle to collide and break. In addition to this, problems such as damage to the hooks often occurred.

Therefore, the present invention addresses the drawbacks of the above-mentioned conventional examples and provides a snap-hook holder that allows the snap-hook to be inserted from either the front or bottom surface and maintains its holding force permanently. It is something.

<Means for solving the problem> The present invention has two parts that extend and protrude from the mounting base part.
The papillary convex portion of the snap-hook is clamped between the ends of the book's parallel restraining rods.

<Operation> Gradually open the tips of two parallel restraining rods to each other,
Since the papillary convex part of the snap hook is clamped elastically at the back of the snap hook, the snap hook is inserted into the holding part while pushing open the elastic piece from the front, or the papillary convex part of the snap hook is inserted from the underside of the elastic piece. By pressing the elastic piece, the elastic piece is pushed open to the left and right, and is held in a predetermined position of the holding part.

<Example> Hereinafter, the present invention will be described in detail with reference to an example shown in the drawings.A holder 1 is attached to and detached from an upper surface of a restraining plate 8 on one side using screws 4, 4.
In this example, two parallel restraining rods 2, 2 are extended and protruded from one side edge of the mounting base 3, and a recess is provided at the tip of the restraining rods 2, 2 to hold the papillary convex portion 10 of the snap hook 9. 5, 5 are formed facing each other, and the front portions of the recesses 5, 5 are provided with guide portions 7 that gradually expand with respect to each other with their respective ends inclined.
is formed so that the papillary convex part 10 of the snap hook 9 can be received from this part, and the papillary convex part 10 is formed on the opposite edges of the lower surfaces of the recesses 5, 5.
Slanted portions 6, 6 are formed to allow the hook to be received from below, and the papillary convex portion 10 of the hook facing into the recesses 5, 5 is held by the mutual elasticity of the restraining rods 2, 2. It is something to do.

Since the holder 1 of the present invention is used by being attached to the upper surface of the retaining plate 8, the lower surface of the snap hook 9 inserted into the holder 1 is pressed by a step corresponding to the thickness of the retaining plate 8, so that the lower surface of the snap hook 9 inserted into the holder 1 is aligned with the upper surface of the retaining plate 8. It is placed at approximately the same height as the bottom surface.

Further, the holding plate 8 may be configured to be able to hold a hook, or may be configured to hold only a snap hook.

The present invention is constructed as described above, and in order to attach a male snap hook, the papillary convex portion 10 of the snap hook 9 is placed on the lower surface of the holding recesses 5, 5 of the holder 1, and then the male snap hook is placed in the direction of the retaining rods 2, 2. Once pressed, the restraining rods 2, 2 are pushed apart to the left and right by the inclination of the inclined parts 6, 6, and then inserted, and the hooks are held by the elastic approach of both the restraining rods 2, 2. In this case, if there is not enough space between the tips of the restraining rods 2, 2 and the fabric, it will be difficult to insert from the bottom. It is also possible for the papillary projection 10 to enter and fit into the holding recesses 5, 5 from the part of the gradually expanding guide 7.

In addition, by making the convex part (not shown) formed on the hook for determining the direction intrude into the opposing gap between the two restraining rods 2, 2, and making the direction of the hook constant, the sewing hole of the hook can be fixed. I try to keep the encounter between the needle and the tip of the needle unchanged.

<Effects of the invention> The present invention is constructed as described above, and the hook can be inserted not only from the bottom of the holder but also from the front, so even if the holder does not rise sufficiently and cannot be inserted from the bottom, there will be no problem. Can be inserted from the front.

In addition, unlike conventional holders, the retention elasticity of the hook does not decrease, and since it is composed of two long restraining rods, the rate of bending strain on the restraining rods due to insertion and removal of the hook is extremely small, and therefore the spring The lifespan of the material can be maintained for an extremely long time.

In addition, it is a highly practical idea that does not require microfabrication as in the past, has a very simple configuration, and has excellent productivity.
