[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thread stand for a sewing machine.

[0002]

2. Description of the Related Art A conventional thread stand of a sewing machine will be described with reference to the drawings. The thread stand shown in FIG. 4 has a thread stand formed on the thread stand 9 up to the upper part of the table 6, and the nut 1
0, 14, and a method of fixing using washers 11, 12 and a wave washer 13 between them has been used. Further, the thread stand shown in FIG. 5 fixes the washer 16 to the thread stand 15 by welding.
A method of fixing the table 6 from below using a washer 17 and a nut 18 has been used.

[0003]

However, since the thread stand 9 as shown in FIG. 4 has a threaded portion formed in the hollow pipe and protrudes high from the upper surface of the table 6, the thread stand 9 shown in FIG. When an external force is applied to the rod 9 , the rod 9 is likely to be broken from the vicinity of the portion A, and the nut 10 must be fitted to the upper side of the screw portion, so that there is a problem that the assembling work is troublesome. In addition, the thread stand shown in FIG. 5 has a problem that the washer 16 is attached to the thread stand 15 by welding, so that the cost is high.

Sewing thread reel stand device of the present invention SUMMARY OF THE INVENTION To solve the above problems, the yarn stand is a hollow shaft
In a thread stand of a sewing machine provided with the rod 1 penetrating from the upper surface to the lower surface of the table 6, the upper surface of the table 6
A projection formed by projecting a part of the thread stand 1 by projection processing.
Between the protrusion 2 and the upper surface of the table 6.
Between the washer 3 and the upper and lower surfaces of the table 6
Screw portion 7 formed below the lower surface of table 6
And a nut 5 screwed into the screw portion 7 .

[0005]

The thread stand of the sewing machine in such a means is as follows.
The protrusion formed on the thread stand serves as a stopper for the washer, and is fixed from below the table using a washer and a nut.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state where the thread stand of the present invention is fixed to a table. Reference numeral 1 denotes a thread standing bar, and reference numeral 2 denotes a projection, which is formed at four locations by projection processing. 3,
4 is a washer, 5 is a nut, and 6 is a table. FIG.
The thread portion 7 is formed so as to be lower than the upper surface of the table with a thread stand.

[0007] The thread stand device of the sewing machine configured as described above is used as follows. Sewing machine 8 as shown in FIG.
The washer 3 is pressed against the upper surface of the table 6 by the protrusion 2. Then, the washer 4 is inserted from the lower surface of the table 6 and tightened and fixed with the nut 5. As described above, the present invention is not limited to the embodiment described above, and can be changed without changing the gist. For example, the number of projections is four, but the number serving as a stopper is Any number may be used, and the shape is not limited.

[0008]

[Effect of the invention] The thread stand of the sewing machine related to the invention is as follows.
A part of the thread stand is projected from the table top by projection processing.
Since it is cast out, ensure the strength of the thread stand
Can be formed, and the formation of the projections is easy and the cost is low.
be able to. Also, place a washer between the protrusion and the table top.
Because it is interposed, if the thread stand is securely attached
In both cases, the work efficiency during assembly can be greatly improved
This has the effect.
