DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for fixing a bobbin and a bobbin for a sewing machine, and more particularly to a fixing device for fixing a bobbin and a bobbin having the same color thread.

[0002]

2. Description of the Related Art When a sewing machine is used, a bobbin wound with a thread having a desired color and quality is selected, a part of the bobbin is wound around a bobbin, and a pair of the bobbin and the bobbin are placed at a predetermined position on the sewing machine. And sewing is performed using the yarns from these as upper and lower yarns. When the sewing operation is completed, the bobbin and the bobbin are removed from the sewing machine and set in different places. When performing sewing work at a later date, the same thread is selected from the same bobbin and the bobbin and attached to the sewing machine.In such a case, it is often experienced that the same bobbin and bobbin have the same thread from the bobbin. It takes time to find things and is often frustrated each time.

[0003]

As described above, since the bobbin and the bobbin having the same yarn are usually stored separately, it takes time to search for a yarn having the same color when used later. However, it is an object of the present invention to eliminate such labor. The present invention extends to the creation of the present invention, considering that it would be convenient if a bobbin and a bobbin having the same yarn could be stored together as a pair.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a bar-shaped portion inserted into a center hole of a bobbin and a bobbin, and means for locking the bar-shaped portion to the bobbin and bobbin, respectively. The above object is attained by a thread winding and bobbin color matching fixture for a sewing machine.

[0005]

According to the present invention, a bobbin and a bobbin having the same thread can be stored together as a pair after the completion of sewing. That is, the rod-shaped part of the color matching fixture of the present invention,
The bobbin and the center hole of the bobbin are aligned and inserted, and fixed by an elastic portion or a fastener by a locking means provided at an end portion or an intermediate portion of the rod portion. As a result, the two can be stored as one body, and the color matching between the bobbin and the bobbin is not necessary prior to the work at a later date, and the irritability before the sewing work can be eliminated and the work can be streamlined.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention can be considered. First, the material of the fixture of the present invention is made of plastic, metal, or wood, but it is particularly preferably made of injection-molded plastic that can be mass-produced at low cost. According to one aspect, the fixing device of the present invention has first and second rod-shaped portions extending from both surfaces of a disk inserted between the bobbin and the bobbin toward the bobbin center hole and the bobbin center hole, respectively. Further, a part of the first and second rod-shaped portions is provided with first and second locking means for locking the bobbin and the bobbin respectively. In such a case, the first
And each of the second locking means locks at the end face or center hole of the bobbin or pincutter with which it is associated. For example, the locking portion that locks on the end surface of the bobbin or the bobbin is made larger at the tip end or the middle portion of both rod-shaped portions than the diameter of the center hole of the bobbin and the bobbin and divided into two to four to make the bobbin elastic. Alternatively, a separate plastic or metal spring may be attached to the center hole or the end face of the bobbin, or a separate plastic or metal spring may be attached to the tip or the middle of both rod-shaped parts and locked to the center hole or the end face. .

According to another aspect of the present invention, there is provided a fastener according to the present invention, wherein a rod-shaped portion penetrating through a center hole of a bobbin and a bobbin is formed at one end of the rod-shaped portion and is locked to one end surface of the bobbin and the bobbin. And a locking portion formed at the other end of the rod-shaped portion and locked to the other end surface or the center hole of the bobbin and bobbin. In such a case, the locking portion is configured to lock to the end face or center hole of the bobbin or spool to which it is associated. The locking portion that locks to the end surface of the bobbin or the bobbin, for example, makes the tip or the intermediate portion on the opposite side of the enlarged head of the rod portion larger than the diameter of the center hole of the bobbin and the bobbin and divides it into 2 to 4 parts. Elasticizing and locking this to the center hole or end face of the bobbin or thread winding, or attaching a separate plastic or metal spring to the tip or middle of the rod-shaped part and locking it to the center hole or end face, In addition, it can be manually locked by means such as a snap.
