Description

  The present invention relates to a sewing thread storage device for storing together a frame wound with an upper thread as a sewing thread and a bobbin wound with a lower thread.

In general, to make a work using a sewing machine, it is necessary to select the color of the thread and the thickness of the thread depending on the fabric. Choosing the upper and lower threads correctly is also a trick to finish the work beautifully.
Therefore, if a frame with an appropriate upper thread and a bobbin with an appropriate lower thread can be stored as a set, it is very convenient for the next use.

  Therefore, conventionally, for example, as can be seen in Patent Document 1, protrusions (2) and (3) having tip portions made spring-like are provided at both ends of the disc (1), and the protrusions (2) and (3) Insert the center hole of the bobbin (5) wound with the lower thread and the center hole of the frame wound with the upper thread (4) to connect the frame wound with the upper thread and the bobbin wound with the lower thread. There are known connectors that can be stored together.

However, in this connection tool, no consideration was given to how the end portion of the lower thread wound around the bobbin is made.
Therefore, there is a difficulty in that the lower thread wound around the bobbin is easily unwound.

  In addition, since the top around which the upper thread (4) is wound is usually provided with a thread end hooking portion such as a notch for holding the end of the wound upper thread. May be connected to the connector after the yarn end is hung on the yarn end hanging portion. However, the thread hook portion provided on the top wound with the upper thread has a drawback that it is not always easy to use.

  Conventionally, as seen in Patent Document 2, for example, a plurality of bobbin holding rods (3) are provided on a circular flat plate (2) that goes around the support column (1), and the upper thread piece The center hole of (4) and the bobbin for lower thread (5) can be inserted into and stored in the bobbin holding bar (3). There is also known a bobbin holding device for a sewing thread in which a cut (3b) is formed so that the thread wound around the bobbin can be prevented from being unwound.

  According to this sewing thread bobbin holding device, the upper thread piece (4) and the lower thread bobbin (5) can be stored together, and the thread wound around the bobbin can be prevented from being unwound. .

  Further, according to this bobbin holding device for sewing thread, the end of the upper thread wound around the upper thread piece (4) is also cut off for the thread stopper provided near the upper end of the bobbin holding bar (3). Since it seems that it can be hooked to (3b), it seems that the usability regarding the upper thread top (4) can be improved.

  However, in this case, the upper thread wound around the upper thread piece (4) is caught on the notch (3b) so as to get over the bobbin 5, so that the upper thread is slanted in the axial direction of the top (4). Since it will be pulled and it will come off from the flange part of a top (4), and it will become easy to produce a big slack, Therefore Usability does not improve.

  When the upper thread piece (4) and the lower thread bobbin (5) are to be moved as a set, the upper thread piece (4) and the lower thread bobbin (5) are moved from the bobbin holding rod (3). Since it is necessary to move in a state where the connected state is released, there is a problem in usability.

  Embodiments of a sewing thread storage device according to the present invention will be described below with reference to the drawings. In each figure, the same reference numerals are given to the same or corresponding parts.

  As shown in FIGS. 1 to 5, the sewing thread storage device 1 of this embodiment includes a sewing thread for storing together a top 30 wound with an upper thread 31 and a bobbin 40 wound with a lower thread 41. A storage tool.

  The sewing thread storage device 1 includes a flat base 10, a bar 20 that is erected on the base 10 and is inserted into the center hole 32 of the top 30 and the center hole 42 of the bobbin 40, and the bar 20 Provided with a slit 21 for holding a thread.

  The slit 21 is a position covered by the frame 30 when the frame 30 is mounted on the rod 20 from the tip 22 of the rod 20 toward the base 10 (from top to bottom in FIG. 1B). 23 are provided. That is, as shown in FIG. 1 and FIG. 2, the distance (height) from the base 10 to the end 10L of the slit 21 on the side of the substrate 10 (lower end in the figure) is H1, and the axial length (height) of the top 30 Is set to H3, the slit 21 is formed so that H1 <H3. As shown in phantom lines in FIG. 1B, the slit 21 can be formed such that the lower end 21L 'reaches the base 10 (or the vicinity thereof).

  According to the sewing thread storage device 1, for example, as shown in FIGS. 2 to 5, the bar body 20 is inserted into the central hole 32 of the top 30 and the central hole 42 of the bobbin 40 as shown in FIGS. By mounting the bobbin 40, the top 30 and the bobbin 40 can be stored together.

  The slit 21 for holding the thread is provided from the tip 22 of the rod 20 toward the base 10 up to a position 23 covered by the frame 30 when the frame 30 is attached to the rod 20. As shown in FIG. 2, when the top 30 is mounted on the rod 20, the slit 21 is exposed on the tip 22 side of the rod 20.

  Accordingly, as shown in FIGS. 2 to 3, when the top 30 is attached to the rod body 20, the end 31 b of the upper thread 31 wound around the top 30 is passed through the slit 21, and is immediately adjacent to the top 30 (the top 30) (near the top surface of 30). By holding the end 31b of the upper thread 31 in the immediate vicinity 24 of the top 30, it is difficult for the upper thread 31 to come off from the flange portion 33 of the top 30 as compared with the above-described prior art, and large slack is less likely to occur.

  With respect to the bobbin 40, after the top 30 is attached as described above, the end 31b of the upper thread 31 is attached to the rod 20 so as to be sandwiched between the top 30 as shown in FIG. Thus, the end 41b of the lower thread 41 wound around the bobbin 40 can be passed through the slit 21 and held in the vicinity 25 (near the upper surface of the bobbin 40) 25. By holding the end portion 41b of the upper thread 41 in the immediate vicinity 25 of the bobbin 40, the upper thread 41 is unlikely to come off from the flange portion 43 of the bobbin 40, and large slack is less likely to occur.

  When the upper thread 31 piece 30 and the lower thread 41 bobbin 40 are moved as one set, the storage tool 1 (FIG. 5) to which these are attached may be moved as it is.

  As described above, according to this sewing thread storage device, the top 30 wound with the upper thread 31 as the sewing thread and the bobbin 40 wound with the lower thread 41 can be stored together, and the upper thread 31, The lower thread 41 can be prevented from being unwound, and the usability and mobility regarding the upper thread top 30 (simultaneous mobility of the top 30 and the bobbin 40) can also be improved.

As shown in FIG. 5, when the frame 30 and the bobbin 40 are mounted on the rod body 20, the rod body 20 protrudes from the frame 30 and the bobbin 40, and the protrusion (the range indicated by H <b> 5) It has a length that can be picked by (H1 + H2 in FIG. 1).
With this configuration, when the upper thread piece 30 and the lower thread bobbin 40 are moved as one set, the protruding portion (H5) of the rod body 20 can be easily picked and moved.

The axial length (height) H3 of the top 30 differs depending on the commercially available top.
Therefore, the height H3 of the top 30 for determining the height H1 from the base 10 to the lower end 21L of the slit 21 means the minimum height of the commercially available tops (minimum). Based on height frames). Specifically, since the minimum height of a commercially available piece is approximately 36 mm, the distance (height) H1 from the base 10 to the end 10 side end (lower end in the figure) 21L of the slit 21 is approximately 35 mm. The following.

  Further, the height H3 of the top 30 for determining the length H5 of the protruding portion means the maximum height among the heights of commercially available tops (based on the top of the maximum height). ). Specifically, since the maximum height of a commercially available piece is about 50 mm and the axial length (height) H4 of the bobbin 40 is generally about 11 mm, the length H5 of the protrusion is about 20 mm. In this case, the length (H1 + H2) of the rod 20 is (H3 + H4 + H5) = 50 + 11 + 20 = 81 (mm) or more. Similarly, when the length H5 of the protrusion is about 10 mm, the length (H1 + H2) of the rod 20 is (H3 + H4 + H5) = 50 + 11 + 10 = 71 (mm) or more.

  Further, since the diameter of the center hole 32 of the commercially available top 30 is about 7 mm and the diameter of the center hole 42 of the bobbin 40 is about 6 mm, the diameter D2 (FIG. 1) of the rod 20 is about 5 mm.

  A taper 20T is provided on the tip 22 side of the rod 20 so that the top 30 and the bobbin 40 can be easily attached to the rod 20 (FIG. 1). The diameter D1 of the tip 22 is about 3 mm.

  As shown in FIG. 1C, the tip 22 of the rod 20 is formed in a V shape toward the slit 21 so that the ends (31b, 41b) of the thread can be easily inserted into the slit 21.

The base 10 has a disk shape.
In order to prevent the base portions 10 of the adjacent sewing thread storage devices 1 from interfering with each other when a plurality of sets of pieces 30 and bobbins 40 are stored using a plurality of the sewing thread storage devices 1, The diameter D3 is made smaller than the outer diameter D4 (FIG. 2) of the top 30.
Since the minimum diameter of the outer diameter D4 of the top 30 that is generally commercially available is about 29 mm, the outer diameter D3 of the base 10 is about 28 mm or less. The outer diameter D3 of the base 10 may be about 28 mm or less and D2 (about 5 mm) or more, but it is desirable that the outer diameter D3 be 14 mm or more, more preferably 16 mm or more in order to ensure stability during mounting.

  The sewing thread storage device 1 as described above can be made of an appropriate material. For example, they can be integrally formed with a synthetic resin (including a silicon resin).

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
