いる。また11は縫い針である。 Conventionally, there have been devices of this type as shown in FIGS. 1 and 2. In Figure 1, sewing machine arm 1
A presser foot 3 provided on the upper surface of the bed 2 is slidably supported on the upper surface of the bed 2 so that it can move back and forth, left and right, and in combination, in conjunction with the cloth feeding device (not shown) of the sewing machine. A lower pressing plate 4 is extended from the tip of the sewing machine in the form of a thin plate and has a hole cut out therein which can be easily sewn. Above it, an upper presser plate 5 is shaped like a triangle and has a substantially similar hole cut out in the area overlapping with the above-mentioned hole of the lower presser plate 4. The upper presser plate 5 is slidable vertically on the front end of the presser foot 3 using the vertical portion 5a as a guide. It is attached and vertical movement is performed by a presser spring 7 with the pin 6 as a fulcrum. In addition, a presser bar 8 is attached to the middle part of the presser spring 7 so as to be able to slide up and down with the presser foot 3 as a guide. It is pressed against the lower surface of the body 10. This slider 9 and pressing body 10
The contact surface of the cloth slides according to the pattern of the cloth feeding device, so it has a smooth finish to minimize friction. A shaft 10a and a locking pin 10b are fixed to the presser body 10, and supported on the sewing machine arm 1 so as to be able to freely move up and down, and are pressed downward by the supply of power (not shown), thereby locking the slider 9, the presser bar 8, and the presser spring 7. The upper presser plate 5 is pressed against the lower presser plate 4 through the upper presser plate 5, and the sewn article sandwiched between the upper presser plate 5 and the lower presser plate 4 is firmly clamped. Note that the presser rod 8 is constructed of a combination of screw bodies so that its length can be adjusted. Further, 11 is a sewing needle.
上記押圧体10を押圧する動力を断てばヒネリ
バネ12の力により第2図のごとく押えバネ7と

完成した被縫製物を取り出して作業が完了する。 Next, the operation will be explained. FIG. 2 shows a state in which the power to the pressing body 10 is cut off, and the upper pressing plate 5 is in the raised position. At this time, the object to be sewn is placed between the lower presser plate 4 and the upper presser plate 5. Then, the pressing body 10
When power is supplied to the upper presser plate 5, as shown in Fig. 1, the upper presser plate 5 moves downward, firmly clamping the workpiece, and moves the sewing machine arm 1, sewing needle 11, etc. according to the pattern of the fabric feeding device. Stitches are formed and sewing is performed by interlocking. At the same time as the end, press the upper press plate 5 again.
rises due to the spring force of the twisting spring 12, so
The completed sewing work is taken out and the work is completed.

つた。また構成部品の精度により押圧体10と滑
り子9の接触面の平行が出ず片当たりを生ずると
いう欠点があつた。 In the conventional cloth feeding device, a rotational moment is applied to the upper presser plate 5, causing the upper presser plate sliding part of the presser arm 3 to twist, and when the power supply to the pressing body is released, the upper presser plate sometimes does not rise. There were drawbacks that led to this. Furthermore, due to the precision of the components, the contact surfaces of the pressing body 10 and the slider 9 are not parallel, resulting in uneven contact.

ことを目的にしている。 The present invention was devised in view of the above-mentioned conventional problems, and the upper presser plate 5 is attached via a presser arm 13 rotatably supported on the upper part of the presser base 3 using a spherical bearing 14.
It is an object of the present invention to provide a cloth presser device in which the upper presser plate 5 can operate smoothly by pressing through the upper presser plate 5.

Regarding FIG. 3, the frame-shaped upper presser plate 5 has a U-shaped branched arm portion 13a at the tip of a presser arm 13 rotatably supported on the upper part of the mounting base 3 by a shaft pin a14, and a shaft. Midway portions on both sides of the upper presser plate 5 are rotatably supported via pins b15. Furthermore, a presser foot height adjustment screw 16 is fixed to the middle part of the presser arm 13. Figure 4 shows details of the presser foot height adjustment screw. Reference numeral 16a designates a spherical bearing, with a slider 9 fixed to its inner ring and inserted into a bracket 16b.The lower end of the bracket 16b is threaded and screwed into the presser arm 13, the height is adjusted, and the retaining nut is tightened. Fix it with 16c.
