Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a male hook or a female hook to an upper hook.

The disadvantages of the conventional device are illustrated in FIGS. 1a, b, c and d.

In Figure 1a, a male hook 1 and a female hook 2 are shown.

FIG. 1b shows a conventional device and an upper hook.

A main body 12 of an upper hook 13 is provided, and a stepped pressing rod 11 is fixed below this main body 12.

A pawl support 10 is slidably attached to the pressing iron 11.

An L-shaped claw 9 is attached to the claw support 10 with a pin so as to be swingable in the left and right directions, and a groove is formed between the tip of the claw 9 and the lower surface of the pressing rod 11.

On the other hand, buttons on the left and right sides of the upper hook 13 push the push-out bodies 6 into the device main body 90.
It is provided so that it can slide left and right.

The female honks 2 are continuously supplied from the upper left side of the extruded body 6 into the guide groove 5 formed by the lower guide member 3 and the upper guide member 4.

The female hooks 2 are attached to the grooves between the pressing rod 11 and the claw 9 of the upper hook 13 by hook holding recesses 7 provided on the top surface of the extruded body 6.

It is the hook extrusion step 8 at the rear end of the hook holding recess 7 that applies force to the female hook 2 during this mounting.

Next, FIG. 1C shows a state in which the upper hook 13 is in contact with the fabric 92 on the pedestal (not shown) on which the female honk 2 is to be attached.

The illustrated dimension a is determined by the difference between the dimension C and the dimension A in FIG. 1.

Next, referring to FIG. 1d, the dimension a will be explained.

That is, the female hook 2 penetrates the fabric 92 and is coupled to the washer 91 on the lower surface, but the upper surface of the fabric 92 and the female hook 2
The dimension between the top surfaces of is a.

The reason why the female hook 2 has a certain dimension between it and the fabric 92 is to connect it to the male hook 1.

The above-described conventional device for attaching a hook (a female hook is exemplified) to an upper hook has the following drawbacks.

That is, when the hook extrusion body 6 attaches the hook 2 to the upper hook 13, it is the hook extrusion stepped portion 8 of the extrusion body 6 that pushes the hook 2, so that the attachment accuracy cannot be maintained sufficiently. For this reason, the structure of the upper hook 13 itself (particularly the claw 9 and the suppression rond 11) must be configured to facilitate the reception of the hook 2, and the accuracy (dimension a) basically required for the upper hook 13 must be configured. In relation to this, the upper hook 13 is as shown in the illustration,
It had to be complicated.

The object of the present invention is to provide a device for easily attaching a honk to the upper hook without complicating the structure of the upper hook itself (using a simple structure commonly used in the past).

The present invention will be explained based on embodiments shown in the drawings.

The female hook 2 and the male hook 1 will be explained separately, with the former being explained in FIGS. 2 to 7, and the latter in FIGS. 8 to 23.
