分狭くなる難点があつた。 Special Publication in 1977 for what was conventionally known as a circular stitching device.
There is an attachment type as shown in -15140. This device has a flange-shaped cover plate that rotates intermittently in conjunction with the vertical movement of the needle bar, and is designed to rotate the cloth using the plate to perform circular stitches. This device requires an intermittent rotation drive mechanism, and this device also requires a considerable amount of space around the needle drop, which has the disadvantage that the field of view around the needle drop becomes correspondingly narrow.

必要である。 Regarding the circular stitching device, in addition to this,
Devices such as those shown in No. 44050 and Japanese Patent Publication No. 50-11825, which consist of a presser foot that presses the fabric on the side of the needle entry, are also known, which perform circular stitches centered around the presser foot by means of the cloth feed movement by a feed dog. It is being According to this device, the structure is relatively simple and the above-mentioned problems are solved without obstructing the field of view around the needle drop, but it is difficult to switch the presser foot from the used position to the non-used position above the fabric. or vice versa, the former is used to switch from the non-use position to the use position.
In No. 44050, the set screw must be loosened, and then the presser foot must be rotated upward or downward to tighten the set screw. Also, in the latter Special Publication No. 50-11825,
It is necessary to raise or lower the push rod and rotate it.

ンタツチで行えるようにしたものである。 The present invention provides the above-mentioned device, that is, a device that has a presser foot that presses the fabric on the side of the needle entry, and performs circular stitching by rotating the fabric around the presser foot through the feed movement of the feed dog. It is possible to switch from the use position where the sewing machine presses down to the non-use position where it does not interfere with normal sewing work above the fabric, or vice versa, with a single touch.

縫いを行うようにしている。 The figure shows one embodiment of the sewing machine body 1.
A presser foot 4 is slidably inserted in the vertical direction into a bracket 3 which is connected to the bracket 3 by parallel links 2, 2 so as to be vertically movable, and is prevented from coming off downward by a collar 5 fixed to the presser foot 4. The collar 5 is always pressed against the bracket 3 by the spring 6. As described above, when the bracket is operated downward, the presser foot needle 4 supported by the bracket 3 presses the fabric on the side of the needle entry side, preferably at a point orthogonal to the feeding direction on the side of the needle entry, with its tip using the feed teeth. The fabric is rotated with the presser foot in the center using the fabric feed motion to perform circular stitches.

業に支障を生じない。 When circular stitching is not to be performed, the bracket 3 is lifted to the dead center position where the parallel links 2, 2 stand upright, and the presser foot 4 is raised to a position where it does not interfere with the sewing work. A bracket 3 is adapted to be removably latched to the sewing machine body in order to hold the raised presser foot in that position, and preferably constitutes a part of the sewing machine body as shown in the figure, and its surface is attached to the sewing machine body. They are on the same page. As a result, in the non-use position where the presser foot is not used, the appearance is almost the same as that of previous sewing machines, and the appearance is not impaired and the sewing work is not hindered.

できる。 As described above, the circular stitching device of the present invention has a simple structure because the rotation of the cloth is performed using the cloth feeding movement by the feed dog, and circular stitching can be performed only with the presser foot that presses the side of the needle drop. It is extremely simple and therefore the field of vision around the needle drop does not become particularly narrow. In addition, switching between the position where the presser foot is used and the position where the presser foot is not used can be performed with a single touch by simply raising and lowering the device.
