Description

  The present invention relates to a presser foot for a sewing machine, and to a presser foot for making a simple and beautiful sewing of parallel line stitching and end stitching during sewing.

  Many stitches drawn on the sewing machine table surface in conventional sewing machines are found in various sewing machine manufacturers, but there is no guide wire drawn on the presser foot. The stitches on the sewing machine table surface are sewn when sewing. By pinching with the presser foot, the stitches are hidden by the sewn product and are often not very useful. Since the conventional presser foot has no guide line such as a guide line, the seam meanders and it is difficult to perform beautiful sewing. For the first time, children who come in contact with the sewing machine and those who use the sewing machine for the first time in a long time are the stitches of the narrow parts and the end stitches. For this reason, when sewing a parallel stitch, a narrow part, a narrow part, etc., it is necessary to perform a laborious work such as marking with a stitch thread or a chain.

  The presser foot has different shapes depending on the sewing machine manufacturer, and there are many pressers with various features as accessories. The machine itself has been developed with high technical capabilities and is equipped with amazing functions, with a single fingertip touch, start, stop or various work instructions can be easily processed to demonstrate its functions. Is the best. However, it is very difficult to create a straight seam that should be simple and clear. It seems that there is a problem with the presser foot that accepts the sewing product first. It is fed backward by the feed dog on the lower side of the presser foot and becomes a seam and becomes realistic. At this time, if the guide line is drawn, you can finish it with a beautiful and beautiful seam if you sew with your fingertips lightly according to it. When sewing, the line of sight always looks at the presser foot needle hole, the needle drop groove, or the front end of the presser foot. I think that line sewing is possible.

  The invention described in claim 1 is a presser foot of a sewing machine having a needle drop hole and a needle drop groove extending from the needle drop hole in a substantially vertical direction, from the needle drop hole of the presser foot to the presser foot. The presser foot is a presser foot of a sewing machine characterized by drawing a plurality of guide wires used at the time of sewing parallel to the needle drop groove to the front end of the sewing machine at a desired interval. A needle drop hole is formed substantially at the center, and a needle drop groove extending straight from the needle drop hole to the front end portion of the flat rectangular plate is formed.

  Three guide lines are drawn at intervals of 1.5 mm from the center of the needle groove to the left and right from the center of the needle groove, and one guide line is drawn 10 mm to the right from the center. The width of the presser foot is about 8mm on the left side from the center of the needle groove, and the right side is about 15mm from the center of the needle groove. By using both ends of this presser foot, a wide range of parallel and straight stitches are easy. By providing a guide wire, it becomes possible to prevent the meandering due to hand shake during thin stitches and parallel stitching, and finish the desired sewing. It is possible to sew easily and neatly without having to put a stain with a stitch thread at the sewing location as in the past, and it is possible to sew several parallel lines by using the width of various guide lines. The parallel stitches with a width of 15 mm or less can be easily sewn with one presser foot. Instructors who teach sewing machines can provide simple and clear explanations when instructing beginners as long as there is a guide line.

In order to easily and beautifully sew end stitches and parallel stitches of the sewing product, draw a plurality of lines as guide lines when sewing the product with a desired width in parallel with the needle drop groove of the presser foot. By embedding a noticeable pigment such as red in the guide line, a clear guide line is obtained. Also, if the width of the presser foot is different from the center of the needle drop groove, it becomes a part of various options such as a wide parallel stitch and a narrow parallel stitch instead of a guide line using the end of the presser foot. . The material of the presser foot may be a material such as metal or synthetic resin. If it is a transparent material, the sewn product under the guide line can be seen through the surface of the presser foot, so you can check whether it is along the guide line. It is also possible to draw a guide wire on a transparent seal and attach or remove it to the presser foot.
In Fig. 4, 14 stitches are sewn to the guide line of the presser foot 8 with the presser foot of 1 and the end is sewn straight. The 9 guide line is also used depending on the dominant hand and the design of the sewing product. In the case of Fig. 4, the place where the sewing is placed on the left side of the needle drop groove is being sewn.
In FIG. 5, after the end sewing shown in FIG. 4 is completed, another parallel stitch is performed. At this time, 5 guide lines are selected on the left side of the sewn product and a parallel stitch with a width of 10 mm is performed.
FIG. 6 is a sewing method in the case of a wide change line of a sewn product or a pasted pocket, etc., where parallel sewing that also serves as a decoration is performed using the end of an 8 mm presser foot that is the width end of 12. First, end stitching is completed using 9 guide lines. Next, if the left end of 12 pressers is sewn as a guide line, 8 mm wide parallel stitching is completed.
Always align the sewn product exactly with the selected guide line, lower the needle to the correct position, press the work clamp with the presser foot, and start sewing slowly. If you turn on the switch, the sewing product will be fed back and forth, but when you sew with your fingertip on the guide line of the width you selected at the beginning, you will have beautiful seams all the way to the end. Finished.

1 is the surface of the presser foot. The presser foot presses the sewing product from the top and feeds the sewing product backward together with the feed dog on the lower side. The pressure of the presser foot is not too strong and not too weak. It is good to do, the current general sewing machine can be adjusted slightly depending on the type of the sewing product. The presser foot is the original purpose to firmly press the sewing product and feed it backwards. We believe that the most important role of the presser foot is to create a beautiful stitch without any meandering or needle drop and safely feed it back. The presser foot not only presses the cloth but also on the surface of the presser foot. Pull the guide line, select a guide line suitable for the purpose so that the incoming sewing product is guided to the correct direction, lightly attach the finger to the sewing product, and feed it backward while assisting the sewing product. Play a role.
The needle drop hole of 2 has a horizontal ellipse because there are more sewing machines with built-in function that the needle swings left and right, but the needle drop hole of the present invention is at one point of the center of the ellipse. Aim the needle hole and feed the sewing product from the front end of the presser foot.
3 The needle drop groove is on the front side of the needle drop hole and is located at the center of the entire presser foot. In some cases, it is possible to confirm the certain position of the sewing product that is visible and hidden from a small gap inside the groove.
4 is the end of the presser foot that is wider than the right needle drop groove of the presser foot, and is about 15 mm from the center of the needle drop groove to the right end, so it is very convenient and easy to use for wide parallel sewing. At the time of wide parallel stitching, it took a lot of time to apply a stitch with a thread or mark with a chaco, but it is better to wear a little troublesome things, such as a decorative sewing machine such as a tension pocket or bag, a thick coat Used for parallel sewing for meetings.
5 is a guide line at a position of 10 mm parallel to the right needle drop groove from the center of the needle drop groove, and a 10 mm width parallel stitch is a width that is routinely used among the sewing widths used for sewing. There is something that can't be measured how quickly and beautifully it can be sewn by pulling it, it is finished neatly by simply aligning the cloth with the guide wire and helping the sewn product gently with the fingertips. Used for meetings, pockets, etc.
6 and 11 are guide lines at a position 4.5 mm wide on the left and right sides in parallel with the center of the needle drop groove. In the case of parallel stitching, it is also a fun work to decide just the right parallel width while taking into account the design of the width of the parallel line which is not too narrow and not narrow and how much to choose, blouse, cutter shirt Used for finishing and so on.
7 and 10 are guide lines that are 3mm wide on the left and right sides parallel to the center of the needle drop groove, and if this guide line is used, the end stitch will be a little deeper. When sewing with the guide line at a position of 10 mm, sewing can be performed parallel to a deeper position than the cloth edge, creating a seam as one design.
8 and 9 are parallel to the center of the needle drop groove, and the width of the guide wire is 1.5mm wide. This guide wire seems to be very useful for sewing neatly and neatly without worrying, so that the sewn product is perfectly aligned with the guide wire so that the sewn product does not leave from the front line of the presser foot. It is important to follow the guide line with the fingertip and feed it in the direction of the needle so that the sewing product is perfectly aligned with the guide line and the mark is not lost. Also, in order to be able to cope with the shape, hand orientation, and dominant hand of the sewing product, the guide wire was drawn to the left and right with the same width from the center of the needle drop groove.
12 is the end of the presser foot, the end of the presser foot that is 8 mm wide from the center of the needle drop groove on the left side of the needle drop groove. The above-mentioned several guide wires and both ends of the presser foot are used for 8 mm parallel stitching. By using this, parallel stitching becomes easy, and parallel stitching over a wide range of widths can be done without much effort.

  Generally, sewing and parallel stitching are also one of the difficult points in industrial sewing machines at sewing factories. Even though it is a single line of parallel stitching, it is the company's motto that beautiful, fast and mass production is part of the company's luck. If so, I think that the presser foot has a guide line. In a wide range of school relations, if you use a sewing machine with a presser foot with a guide wire once in the fields from beginner to advanced, vocational school, profession specialized in sewing machine use, etc. It is thought that you will notice.
