BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quilting ruler bar for a sewing machine, which is used to form a seam parallel to the previous seam during quilting.

0002

2. Description of the Related Art A quilting ruler is used to guide stitches to keep them parallel when sewing quilting fabric. For example, a ruler bar for quilting is attached to and detached from a presser foot 20 of a sewing machine as shown in FIG. Possible arrangements are known. This quilting ruler bar 21 consists of a mounting part 22 attached to the presser foot 20 and a seam matching part 23 extending perpendicularly from the mounting part 22. It is shaped so that it is slightly bent upward.

FIG. 3 shows a quilting ruler 21 used to sew seam b parallel to seam a on the right side. The attachment portion 22 is attached to the presser foot 20 so that the placement portion 23a of the bent corner of the seam matching portion 23 is placed on the upper surface of the seam a. In this way, the mounting section 2
By advancing the cloth so that 3a always runs along the upper surface of seam a, seam b is sewn parallel to seam a. At this time, the tip of the seam matching portion 23 is slightly tilted upward so that it does not create resistance when the object to be sewn 24 moves.

0004

[Problem to be Solved by the Invention] However, if the object to be sewn is large, it cannot fit into the pocket (not shown) between the sewing machine arm and the sewing machine leg, so it is difficult to sew the sewing machine as shown in Fig. 4. It becomes necessary to perform sewing work by placing c on the left side of the sewing machine needle 25. In this case, use the quilting ruler stick 2.
It must be installed so that the seam joining part 23 of No. 1 is on the left side of the sewing machine needle 25, but since the tip of the seam joining part 23 is formed so that it is tilted upward when it is installed on the right side of the sewing machine needle 25, it cannot be installed in the opposite direction. When attached to the seam c
There was a problem in that the material to be sewn 24 did not slide properly due to the sewing material getting caught in the material.

[0005] Therefore, according to the present invention, regardless of whether the stitching part of the quilting ruler bar is on the left or right side of the sewing machine needle,
To provide a quilting ruler bar for a sewing machine which can perform sewing work without biting into seams.

[0006]

[Structure of the invention]

[0007]

[Means for Solving the Problems] The means taken in the present invention to solve the above problems is to attach and detach the presser foot that urges the workpiece so as to be perpendicular to the sewing direction of the workpiece. In a quilting ruler bar for a sewing machine, the sewing machine has a mounting part that can be attached to the sewing machine, and a seam matching part that is bent approximately perpendicularly from the mounting part and is arranged along the left or right seam. , a ruler rod for quilting of a sewing machine, characterized in that a circular placing portion is formed to be placed on the upper surface of the seam.

[0008]

[Operation] The above problem operates as follows. In other words, since the mounting section that is placed on the top surface of the seam is formed in a circular shape, the circular mounting section will slide on the top surface of the workpiece regardless of whether the mounting section is placed on the left or right side of the sewing machine needle. . Therefore, the seam joining portion does not get caught in the seam as the object to be sewn moves forward.

[0009]

[Embodiment] An embodiment of the present invention will be explained based on FIGS. 1 and 2. The quilting ruler bar 1 of this embodiment is L-shaped and is adapted to be detachably attached to a holding portion 7 of a presser foot 6 of a sewing machine. The quilting ruler bar 1 is composed of a mounting part 2 attached to a holding part 7 and a seam matching part 3 bent approximately perpendicularly from the mounting part 2. The distal end of the seam joining part 3 is provided with a circular mounting part 4 that extends and then bends back again, and the leading edge part 5 is designed not to protrude below the seam joining part 3. .

FIG. 2 shows a state diagram in which the stitching portion 3 of the quilting ruler bar 1 is arranged to be on the left side of the sewing machine needle 8. The quilting ruler stick 1 is the sewing machine needle 8
and the mounting section 4 are fixed to the holding section 6 so that they are attached with a desired gap. In this embodiment, the sewing machine is attached so that the stitch A to be sewn is sewn parallel to the stitch B two previous stitches as a reference. In this way, the user can make the seam A parallel to the previous seam B by performing the sewing work while keeping the mounting portion 4 tracing the upper surface of the seam B. At this time, since the circularly rounded mounting portion 4 comes into contact with the upper surface of the seam B, it does not get caught in the upper surface of the seam B and smoothly contacts the upper surface of the workpiece 9 in accordance with sewing.

Furthermore, even if the quilting ruler bar 1 is installed in the opposite direction to that shown in FIG. Since the placing part 4 has a circular shape, it smoothly slides on the object to be sewn with its curved surface.

In this embodiment, one end of the quilting ruler rod is bent into a circular shape, but the tip of the quilting ruler rod may be shaped into a ring shape or a disk shape.

[0013]

[Effects of the Invention] According to the present invention, since the mounting portion of the quilting ruler rod that guides the sewing object is circular, it does not matter whether the sewing machine needle is guided along the seam on either the left or right side. , it slides smoothly without biting into the workpiece. Therefore, one quilting ruler bar can guide the stitches on both the left and right sides, making the work extremely easy when quilting a large workpiece.
