JP2519018Y2 - Retainer for bobbin thread to bobbin thread - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a novel upper thread bobbin for attaching a lower thread bobbin to an upper thread bobbin when the thread is finished after the sewing of the sewing machine is finished. A retainer for a bobbin bobbin.

[Conventional technology]

Although the upper thread and the lower thread are used for hooking a sewing machine, the lower thread bobbin is usually much smaller than the upper thread bobbin because the amount of the lower thread used is small.

The upper thread bobbin has a tubular shape, but in many cases, the upper thread bobbin is formed to have a larger diameter toward the lower end, and the lower end is often provided with a brim-shaped seat that inclines downward toward the outside.

On the other hand, the bobbin thread bobbin includes a bobbin with a collar provided at both ends of the tubular core, a tubular bobbin having the same tubular shape as the bobbin thread bobbin, etc. It is about the size.

Conventionally, when the thread is to be stored after use, the upper thread bobbin is stored upright on a shelf, but the lower thread bobbin is stored side by side in a shallow case.

[Problems to be solved by the device]

Since the upper thread and the lower thread must match in type such as color, yarn end, quality, and thickness, it is necessary to match the types, so the upper thread bobbin and the lower thread bobbin are used as a pair, Conventionally, the lower thread bobbin was not attached to the upper thread bobbin, so a sewing company handling a very large number of kinds of threads searches for a lower thread bobbin of the same kind as the upper thread bobbin. It was very troublesome.

In other words, since the upper thread bobbin can be placed upright, the upper thread bobbin can be arranged on a large shelf, and since the area for winding the thread is large and the type of thread can be easily identified, the thread to be used is relatively selected. It is easy, but the bobbin bobbin is stored in the case, and it is difficult to identify the thread type because it is small, so it takes a very long time to find the same thread as the upper thread bobbin. Sometimes it is lost, and because the bobbin bobbin to be used cannot be found, useless work to wind the thread from the upper bobbin to the new bobbin bobbin occurs several times a day. This was one of the factors that hindered work efficiency.

In view of the above situation, the present invention is capable of attaching the lower thread bobbin to the upper thread bobbin after the thread is used, so that the lower thread of the same thread as the thread of the upper thread bobbin is attached. It is an object of the present invention to provide a retainer for a lower thread bobbin with respect to an upper thread bobbin that saves the trouble of finding the bobbin.

[Means for solving the problem]

In order to achieve the above object, the present invention constitutes a retainer for a lower thread bobbin with respect to the upper thread bobbin by providing a retaining piece to which the lower thread bobbin is attached with a catching portion which is stopped at an end edge portion of the upper thread bobbin. .

[Action]

Since the retainer of the lower thread bobbin with respect to the upper thread bobbin is configured as described above, when using this, attach the lower thread bobbin to the holding piece and then hook it on either the upper or lower edge of the upper thread bobbin. To do.

In this way, if you attach the lower thread bobbin to the upper thread bobbin and arrange them on the shelf, by removing the upper thread bobbin of the used thread from the shelf at the same time when using the thread for hanging the sewing machine, Since the lower thread bobbin of the thread is taken out, the trouble of finding the lower thread bobbin can be completely saved.

Since the lower thread bobbin is attached to the upper thread bobbin at the time of shelving, the lower thread bobbin can be removed and the upper thread bobbin and the lower thread bobbin can be immediately set in predetermined positions without making a mistake in the thread type. .

The structure of the holding piece is not particularly limited as long as the lower thread bobbin can be stably attached to the holding piece.

The structure of the hooking portion is not particularly limited as long as the hooking portion can be stably hooked on the edge portion of the upper thread bobbin.
However, if the structure is such that the lower thread bobbin can be stored inside the upper thread bobbin, the lower thread bobbin will not be visible and the appearance will be good, and stability will be obtained when the upper thread bobbin is stood up and finished. desirable.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 5 show an embodiment, in which the cage P is formed by bending and processing two strips 1 and 2 made of an elastic material to combine them with the retaining piece 3. Stops 4 and 5 are configured.

The first strip 1 is formed as a pair of gripping arms 6, 6 by bending it into an arc shape having a slightly larger number than a semicircle, and has an opening 9 between its ends.

The second strip 2 has an inverted U-shaped sandwiching portion 7 sandwiching the base end portion of the first strip 1 welded to the proximal end portion thereof.
A receiving piece 8 projecting inward from one end of the holding arm 6 is formed, and the holding piece 3 is constituted by the gripping arms 6 and 6.

In addition, with respect to the strip plate 2, a sub-engagement portion 4 is formed by standing up from the other end of the sandwiching portion 7 with a little space therebetween, and is further projected outward and reversed to be the main hook portion. 5 is formed.

Regarding the use of the retainer P, first, the lower thread bobbin 13 is attached to the holding piece 3, and then the upper thread bobbin 14 is hooked.

Since the holding piece 3 has a pair of gripping arms 6 and 6, when the bobbin thread bobbin 13 is attached, the open port 9 between the tips thereof is directed toward it, and the bobbin thread bobbin 13 is placed between the gripping arms 6 and 6.
Clamp 13 winding threads 15.

Since the gripping arms 6 and 6 are made of an elastic material, the gripping arms are elastic regardless of the thickness of the bobbin and the wound yarn
As long as 15 is sandwiched, the opening 9 is smaller than the diameter, so the lower thread bobbin 13 does not come off from both gripping arms 6 and 6, and the upper and lower collars 16 and 16 of the lower thread bobbin 13 have both gripping arms. It becomes a stable mounting state which is hung on 6 and 6. The receiving piece 8 receives it so that the lower thread bobbin 13 does not tilt, and thus plays a supplementary role for stability.

The needle thread bobbin 12 shown in FIGS. 1 and 4 is a tubular body.
The lower end of the collar 10 has a collar-shaped seat 11 that opens downward. As shown by the solid line in FIG. 4, the main hooking portion 5 is sandwiched between the end edges of the collar-shaped seat 11 to lower the bobbin bobbin. 13 upper thread bobbin 12
It can also be stored by hanging it on the upper end portion of the upper thread bobbin 12 as shown by the alternate long and short dash line. Further, although not shown, the sub-locking portion 4 can be held horizontally in the upper thread bobbin 12 by sandwiching the auxiliary hooking section 4 on the upper edge of the upper thread bobbin 12 (similar to FIG. 7). ).

When the cage P is attached to the lower end edge of the upper thread bobbin 12, the upper thread bobbin 12 is slightly inclined when it is erected, but the stability is not lost.

The upper thread bobbin 12 shown in FIG. 5 has a substantially straight shape, but since the upper end opening is narrow and the lower thread bobbin 13 cannot enter from there, in this case as well, the main hook 5 The lower thread bobbin 13 is housed in the lower end portion by sandwiching.

[Other Examples]

FIG. 6 and FIG. 7 show another embodiment. In this case, the retainer P is integrally formed of plastic as a whole, and has a holding piece 3 composed of a pair of gripping arms 6, 6. The latching portion 4a is formed by providing an inverted L-shaped projecting piece at the base end of. Further, projecting pieces 17, 17 sandwiching the lower thread bobbin 13 are vertically provided at the base end of the holding piece 3.

In this case, the cage P is preferably used with the hooking portion 4a sandwiched between the upper edge portion of the needle thread bobbin 12.

In any of the above embodiments, since the gripping arms 6 and 6 are formed of elastic material, the lower thread bobbin 13 can be attached with one touch, and the upper thread bobbin 12 can be easily attached.

[Effect of device]

As described above, according to the present invention, since the holding piece to which the lower thread bobbin is attached is provided with the hooking portion that hooks on the end edge of the upper thread bobbin, according to this retainer, when the upper thread bobbin is finished, Since the lower thread bobbin can be attached, when you use the thread next time for hooking the sewing machine, you will never mistake the upper thread and the lower thread, and look for a bobbin of the same type as the upper thread. Since the labor is saved and the bobbin bobbin is not lost, it has a remarkable effect in improving the working efficiency of sewing using various kinds of threads.
