Patent application filed in 1984 as a cloth holder for conventional sewing machines.
There is No. 158633 (Japanese Unexamined Patent Publication No. 57-81369). This presser foot has a hollow frame, and a plurality of mounting arms each having a lever plate biased in one direction by a spring are disposed on the side of the hollow portion of the presser foot. An intermediate presser, which displaces a lever plate and cooperates with the outer presser to sandwich the fabric between the fabric support bases and press down and spread it onto the throat plate, the outer presser and the intermediate presser are arranged on the support base. The respective positions can be raised and lowered by operating a lever on the operating arm.

Among these conventional techniques, in Japanese Patent Application No. 55-158633 (Japanese Unexamined Patent Publication No. 57-81369), a lever plate is displaced by the vertical movement of an intermediate presser, and after pressing the cloth with the upper and lower pressers, the center The structure is such that the presser cloth is stretched so that the cloth is spread outward using a lever board. Therefore, the cloth is
Although it is reliably stretched, the structure of the entire cloth holder is complicated.
The weight of the frame becomes heavy, which is disadvantageous for high speeds, and also has the drawback of increasing costs.

Therefore, in this invention, in order to fully stretch the cloth and reduce the gap between the needle plate and the needle plate, and to prevent skipped seams from occurring even with thin materials, the shape of the upper presser foot is changed to the lower end of the outer peripheral side. Make sure to press the fabric from the outer circumferential surface of the upper presser foot, and then press it from the inner circumferential surface by placing the end that faces more toward the inner circumference upward (shallowly) relative to the surface of the presser foot to create a two-stage presser foot. is the technical issue.

The technical means taken to solve the above technical problem is that the upper surface of the lower presser foot has a semicircular cross section or
A lower presser foot is attached with an elastic body having a semicircular shape with a nearly vertical outer peripheral side, and an inner cross-sectional shape of the upper presser foot is formed to have approximately the same cross-sectional shape as the outer cross-sectional shape of the lower presser foot. The lower end of the inner circumferential side of the upper presser foot is made shallower (upward) in the Y dimension than the lower end of the outer circumferential side.

The said technical means work as follows. In other words, the operation of the cloth holder is exactly the same as in the conventional method, and in the first step, the top of the lower presser foot and the lower end 5a of the outer circumferential surface of the upper presser foot slide to hold the cloth, and then in the second step. The cloth 9 pressed by the lower end 5a of the outer peripheral side of the upper presser foot is pressed again by the lower end 5b of the inner peripheral side of the upper presser foot, which is provided shallower in the Y dimension, thereby holding the cloth so that it touches the upper surface of the throat plate. do. To explain the operation in more detail, the upper presser foot 5 attached to the fabric holder attachment part 3' of the feed arm 3 provided in the space with the sewing machine arm 1 and the bed 2,
As with conventional sewing machines, the presser foot lifting arm 4 operates,
It has a structure that can be raised and lowered. The lower cloth support 6 is located on the upper surface of the bed 2 and is integrally attached to the feed arm 3. In the first step, as shown in FIG. 4, the lower end 5a of the outer peripheral side of the upper presser foot 5 comes into sliding contact with the cloth 9, and as shown in FIG. The lower presser foot 7 made of is deformed and the cloth 9 is held at the same time. As a second step, the lower end 5b of the inner surface of the upper presser foot 5 is inserted into the inner side of the lower presser foot 7, and the cloth 9 is inserted into the small protrusion 8 provided on the throat plate as shown in FIG.
Hold the pressure until the tension is reached.

The present invention produces the following unique effects. That is, it has a structure in which the presser foot piece is simply provided on the conventional upper presser foot or the lower cloth support, and because it can be manufactured lightweight, it can respond to feeding operations at high speed and with high precision. Furthermore, by simply lowering the upper presser foot, it is possible to stretch a stretch of the cloth to be clamped and then completely hold the cloth, making it possible to easily hold thin materials, stockinated materials, etc., which had been a problem in the past. Since the presser foot is made of an elastic material, it can immediately follow changes in the thickness of the fabric and hold it, so it also has the effect of being able to hold and maintain fabrics other than those whose thickness is constant.
