Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a presser foot device in a sewing machine such as a pattern bar-tack cycle sewing machine that performs sewing with a hook.

[Conventional technology]

Conventionally, when sewing a hook as shown in FIG. 3 onto a workpiece, it was done by hand.

In FIG. 3, 10 indicates a hook, 8 indicates a hook upper tab portion, and 9 indicates a sewing hole.

[Problem that the invention attempts to solve]

Conventionally, these hooks were sewn by hand (hand-stitched), which required technical skill, took a considerable amount of time, and had problems such as variations in the quality of the sewing.

This idea was made to solve the above-mentioned problems.The specified hook is fixed to the hook holder on the presser foot, and the sewing machine sews a predetermined sewing area in a predetermined pattern. The purpose is to sew semi-automatically using a sewing machine such as a cycle sewing machine.

[Means for solving problems]

The cloth pressing device according to this invention is equipped with a pressing device for attaching a hook, and the presser device for attaching the hook is pressed from one end to a substrate having a hook holder hole for holding the hook, and the presser device for attaching the hook is pressed from one end to the substrate. The hook holder is configured to be movable and has a portion inserted into the hook holder hole at its tip end, and the hook holder hole side wall of the substrate facing the insertion portion of the hook holder is provided with the hook holder hole. A slope is formed to guide the hook toward the hook holder hole.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, 1 is a base plate, 2 is a hook holder, 3 is a hook holder with a stopper part 4, 5 is a retaining spring for the hook holder 3, 6 is a hook holder hole, and 7 is a guide for inserting the hook 10. It's a slope. In addition, Fig. 2 shows − of Fig. 1.
A line cross-sectional view is shown.

The device according to this invention is constructed as described above, and the hook 10 shown in FIG. 3 is slid on the guide slope 7 shown in FIG. 1 in the direction of the arrow while being pressed with the finger of the hand. Before long, the finger comes into contact with the hook presser 3 and presses the spring 5, which holds the hook presser, with the finger. The hook 10 is then inserted into the hole 6 of the hook holder guide. When the finger is released from the hook 10, the hook presser 3 presses the hook 10 through the force of the spring 5, and the hook 10, which has entered the hook holder guide section 6, is fixed.
Next, in operation of a cycle sewing machine (not shown), the 93 holes shown in FIG. 3 are sewn in a predetermined pattern (not shown), and the hook is sewn onto the cloth.

In the above description, the hook 10 is shown and described as a male type hook, but it goes without saying that a female type hook 10, which is paired with this hook 10, has the same function and effect.

[Effect of idea]

As described above, according to this invention, the presser foot device that fixes the hook is attached to a cycle sewing machine that can sew in a predetermined pattern, so that it can be sewn with stable quality of hook sewing and a remarkable improvement in work ability. can get. Furthermore, there is no need for any highly skilled sewing techniques, and it is possible to obtain stable products of the same quality.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing an embodiment of the invented device, FIG. 2 is a sectional view taken along the line -- in FIG. 1, and FIG. 3 is a perspective view showing a hook. In the figure, 1 is a base plate, 2 is a holder, 3 is a hook presser, 4 is a stopper, 5 is a spring, 7 is a guide slope, and 10 is a hook body. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] In a sewing machine that sews a certain pattern stored in advance in an electronic memory element, the sewing machine is equipped with a presser foot device for attaching a hook for sewing the hook onto a workpiece, and the presser foot device for attaching the hook is equipped with the presser foot device for attaching the hook. , a board having a hook holder hole for holding the hook, and a hook presser that is pressed from one end and is configured to move on the board and has a portion at its tip to be inserted into the hook holder hole.
