Description

[Detailed description of the invention] "Industrial application field" This invention relates to an attachment that is attached to a sewing machine when performing dropstitching around the belts of skirts and slacks so that the seams are not visible from the outside. It is.

``Prior Art'' As a conventional drop stitch attachment attached to a sewing machine for attaching this type of belt with interlining to the body, the one shown in Fig. 5 is known. .

Reference numeral 1 in the figure is a cloth presser foot for fixing the cloth to the throat plate 2. A split groove 1b is formed in the presser foot 1a of the presser foot 2, and an insertion hole 1c for the needle 3 is formed at the base end of the split groove 1b. A dropping guide 4 is installed between the split grooves 1b so as to be parallel to the needle 3, and an inclined plate 6 is attached to one side of the presser foot 1a via a slide mechanism 5 to adjust the inclination angle. It has an adjustable configuration.
When drop-stitching the belt onto the body using the attachment, first attach the interlining to the inside of the belt, leaving an edge of a predetermined width, and place the edge on the back side of the body. With the attachment at a predetermined location, set it diagonally along the inclined plate 6 of the attachment with the back side facing up. Then, by restraining the fabric near the needle 3 with the presser foot 1, the split groove 1b of the presser foot 1a is
After the fabric at the seam part is raised up by the dropping guide 4, the belt is sewn onto the body by dropping stitching while placing a hand on the belt part and feeding the fabric first.

``Problem that the invention aims to solve'' However, in the case of the conventional drop stitch attachment mentioned above, the belt is placed upright along an inclined plate and sewn onto the body, so it is difficult to operate it. This is not easy and requires a certain degree of skill to carry out drop stitching, and there are problems in that the sewing speed is slow and work efficiency is not very good.

There is also a drop stitch attachment that allows you to sew in a flat state without the belt standing upright, but this attachment is designed to sew from the front side of the belt with the edge fabric located on the back side of the body, so it is often Since it is necessary to sew while looking at the back side and confirming whether the seam allowance of the edge cloth is sewn to a certain width, there is a limit to the sewing speed and there is a problem that work efficiency is poor.

This invention was made in view of the above-mentioned problems, and is a device that simplifies the operation of dropping stitches and allows even unskilled people to easily, reliably, and quickly perform dropping stitches. It is intended to provide attachments.

``Means for Solving the Problems'' In order to solve the above-mentioned problems, the present invention provides a slide plate provided on the side of the throat plate in which the needle holes are formed. Attach a guide member on which a straight fabric pressing surface is formed, form a dropping guide whose tip is located slightly in front of the needle hole on an extension of the pressing surface, and connect this dropping guide to the needle plate. The presser foot is disposed in a split groove formed in the presser foot located near the needle hole, and a stepped portion is provided on the bottom surface of the presser foot to form a presser surface that is continuous with the presser surface of the guide member.

"Function" According to the attachment of the present invention, if one side of the belt-shaped fabric is pressed against the pressing surface of the guide member and fed toward the needle hole, the fabric will be displaced in the lateral direction. It is sent quickly and reliably to a fixed position without any trouble. In addition, as the fabric is fed along the pressing surface, as the seam portion passes through the release guide, it is forcibly fed between the grooves of the presser foot and becomes raised. , Even if the sewing is done in a flat state, the dropped stitches are reliably performed. Furthermore, even after passing through the needle hole, the fabric is fed to the other side of the presser foot without shifting laterally due to the bottom surface of the presser foot and the step formed on the bottom surface of the presser foot. You can reliably sew the specified seams.

``Example'' The drop stitch attachment of the present invention will be described below with reference to the drawings. Figures 1 to 4 show an embodiment of the present invention, which is a drop stitch attachment attached to a sewing machine used when attaching a belt to the periphery of a body by drop stitching.
