DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a presser of a sewing machine used for sewing a fastener to a cloth.

[0002]

2. Description of the Related Art As shown in FIG. 20, a conventional presser 1a of a sewing machine comprises an attachment portion 12, a presser 13 having a needle hole through which a needle 14 is inserted, and a set screw 15;
Concave portions 16 and 17 are formed on the lower surface of 3, and the fastener 18 is inserted into the concave portions 16 and 17 to attach the fastener to the cloth material.

[0003]

However, in the conventional method of attaching a fastener to a cloth material using the presser 1a of the sewing machine, the female portion 18 of the fastener to be raised is stretched sideways by hand and flattened. It has to be sewn, which is dangerous, and has the disadvantage of taking too much work.

In addition, the presser 1a of the sewing machine in which the recesses 16 and 17 are provided on the lower surface of the presser 13 as in the prior art does not have a pressing force for stretching the picked-up portion 18 of the fastener that has risen sideways. There is a drawback that sewing cannot be performed at a position closer to the female part 18.

[0005] The presser 1 of the sewing machine according to the present invention makes it possible to feed the fastener 8 of the fastener to be raised to the needle tip while pressing it securely and keeping it flat. An object of the present invention is to provide a sewing machine presser which can safely and smoothly meet at a position very close to the sewing machine 8.

[0006]

In order to solve the above-mentioned problems, the present invention is characterized in that a presser provided with a needle insertion groove, an L-shaped guide and a pressing member is rotatably mounted on a mounting portion. Of the presser of the sewing machine.

[0007]

Next, the presser of the sewing machine according to the present invention will be described.
This will be described in detail with reference to the drawings. 1 is a perspective view of a presser of the sewing machine of the present invention, FIG. 2 is a left side view of the presser of the sewing machine of the present invention, FIG. 3 is a front view of the presser of the sewing machine of the present invention, and FIG. 4 is the present invention. FIG. 5 is a rear view of the presser of the sewing machine according to the present invention.

As shown in FIGS. 1, 2, 3, 4 and 5, a presser 1 of the sewing machine comprises an attaching portion 2 and a presser portion 3, and a needle of the sewing machine is inserted into one side of the presser portion 3. The needle insertion groove 6, the L-shaped guide 4, and the pressing member 5 are provided.

As shown in FIG. 2, the tip 3 of the needle insertion groove 6
The L-shaped guide 4 is provided at a position a. The tip of the L-shaped guide 4 is bent downward, and is integrally formed on one side of the holding portion 3. A pressing member 5 is formed integrally with the pressing portion 3 near the distal end portion 3 a of the L-shaped guide 4.

As shown in FIG. 3, the positional relationship between the L-shaped guide 4 and the pressing member 5 is determined by the lower end surface 4a of the L-shaped guide 4.
Are located at substantially the same horizontal position as the lower surface 5a of the pressing member 5.

[0011] As shown in FIG.
A spring 5a is provided at a portion where the pressing portion 3 is rotatably attached to the mounting portion 2 as shown by an arrow, and the pressing portion 3 is returned to the original position by the spring 5a. It has a structure that returns.

As shown in FIGS. 2 and 4, the pressing portion 3 rotatably mounted on the mounting member 2 has a tip 3a of the pressing portion 3 curved slightly upward.
