Description

[Detailed Description of the Invention] The present invention relates to a sewing machine needle, and its purpose is to provide a sewing machine needle that allows easy replacement of the needle.

Conventionally known sewing machine needles have a needle trunk and a needle point on one side in the longitudinal direction of the handle.

With such needles, when the used needle breaks or wears out and you need to replace it with a new one,
When replacing a needle with a different needle diameter, you must take the previously used needle out of the drawer and store it in a designated place, such as a needle bag or needle case, and then take out the new needle and attach it to the sewing machine. However, it was very time-consuming to take out and replace, and it was also complicated to store. Particularly in sewing, a thin needle is used to sew thin materials, and replaced with a thicker needle to sew thick materials. Since the needle is removed from the needle bag, inserted into the needle bar, tightened with screw, and moved on to sewing, it is necessary to repeat the operation of inserting the stored needle each time, which poses a problem in handling. In addition, there is a sewing machine needle that uses a single thread to sew Japanese clothing, etc. in the same way as hand sewing, with needle tips at both ends and a hole in the center for passing one thread. Official gazette and Japanese Patent Application Publication No. 1983-
Although it has been proposed in publications such as Publication No. 29243, it is not possible to sew with two threads using an upper thread and a lower thread using an inner hook, and the needle cannot be used due to breakage or wear. It was no different from a needle with a needle tip and had the same drawbacks.

The object of the present invention is to provide a sewing machine needle that is easy to handle and inexpensive in order to eliminate these drawbacks of the conventional sewing machine.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

The present invention is characterized by having a vertically elongated handle and a needle tip connected to the handle and having a long groove and a needle hole on both sides of the handle in the longitudinal direction. Fig. 1 shows one embodiment of the invention. This shows that. In the figure, reference numeral 1 denotes a vertically long handle, and needle trunks 2, 2' and needle tips 3, 3' are provided on both sides of the handle in the longitudinal direction. The needle trunks 2 and 2' are provided with thread guide long grooves 4 and 4, respectively.
4' and needle holes 5, 5' are formed. Although this needle is an example in which the needle trunks 2 and 2' have different thicknesses, the present invention is not limited to this, and includes needles with the same thickness and needles with different shapes, structures, etc.

Figure 2 shows an example in which the tip of the needle is rounded into a hemispherical shape 6, and this may be provided on one or both sides in the longitudinal direction of the handle. Of course.

In the embodiment shown in FIG. 1, the handle 1 has the length of two handles, and half of it is used as the handle of only one of the handles.
If the handle portion 1' is shared as shown in FIG. 3, materials can be saved.

As described above, according to the present invention, since the needle tip portion with the long groove and the needle hole is provided on both sides of the handle in the longitudinal direction, when replacing the needle, the set screw on the needle bar of the sewing machine can be loosened. All you have to do is remove it, rotate it 180 degrees, and attach it to the needle bar.Also, if the sewing machine has a rotatable needle attachment part, there is no need to remove the needle, which eliminates the hassle of replacing the needle. can be easily done.

Therefore, if a needle has needles with the same thickness on both sides, and one of them is damaged or worn out and needs to be replaced, the needles may have different thicknesses or different types of needles. With different combinations of needles, needles can be replaced easily and quickly depending on the object to be sewn.

Also, since it has two needles,
It also has the effect of making the storage and handling of the needle very easy.
