  In recent years, it has been desired to perform practical training efficiently as home economics lesson time is shortened. In sewing training, work using a ruler such as marking work, especially the work of measuring and marking the required dimensions, is one of the processes that require time.

  For example, when a cutting line is to be attached while securing a sewing allowance of a predetermined width on the outside of the finish line, first, a necessary sewing allowance is measured and marked with a sewing tool. After repeating this operation along the finishing line, a line (cutting line) for connecting the marks to each other is drawn. At this time, a child unaccustomed to the conventional bamboo ruler tends to make a mistake in reading the scale of the bamboo ruler. If you read the scale incorrectly and mark it at the wrong position, the final cutting line will be distorted and you will have to start over. Therefore, the work using the ruler takes a lot of time for teaching, and it is a heavy burden for both the instructor and the child receiving the guidance.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sewing tool that can easily perform a marking operation by measuring necessary dimensions.

  The sewing tool holder for achieving the above-mentioned object is a sewing tool holder having a band shape with a constant width, and the reference length is set such that the interval between the scales provided on one side of the long side is more than 10 mm and less than 50 mm. L (however, the reference length L is an integral multiple of 5 mm).

  According to the said structure, compared with the conventional bamboo ruler in which a scale is provided at 1 mm or 5 mm space | interval, while adjacent scales are located away, the whole number of scales also decreases. For this reason, when measuring a length that is an integral multiple of the reference length L using a sewing ruler, it is difficult to make a mistake in reading the scale. As a result, the burden on the instructor and the child receiving the instruction is reduced.

  Note that many of the learning materials currently being sold for sewing training are an integral multiple of a specific length (for example, 15 mm or 20 mm) as the length of the sewing allowance or bending allowance to reduce the occurrence of measurement errors. Only the value is used. The sewing ruler of the present invention is applied to such a learning material, and the reference length L which is a scale interval is set to the specific length used in the learning material. Therefore, when the sewing tool of the present invention is used in the sewing training using the learning material described above, it is difficult for the scale to be read erroneously, and the work of measuring and marking the necessary dimensions can be easily performed. .

Moreover, it is preferable that the length of the short side is the reference length L.
The reference length L is preferably 15 mm or 20 mm.
A numerical value representing the distance from the first end is attached to the scale located on the first end side of the center on one side of the long side, and on the second end side of the center. It is preferable that a numerical value indicating a distance from the second end portion is attached to the scale that is positioned.

  It is preferably formed of a transparent synthetic resin material.

  According to the sewing tool holder of the present invention, it is possible to easily perform the work of measuring and marking necessary dimensions.

The top view of the sewing tool case of embodiment. (A), (b) is a figure which shows an example of the usage method of a sewing implement. (A), (b) is a figure which shows an example of the usage method of a sewing implement.

Hereinafter, an embodiment embodying the present invention will be described in detail with reference to the drawings.
The sewing tool holder 10 of the present embodiment is a sewing tool holder used for sewing training using a learning material such as an apron making kit in school education.

  As shown in FIG. 1, the sewing ruler 10 of the present embodiment is a straight ruler having a band shape with a constant width, and is formed of a transparent synthetic resin material. A main scale 20 having a reference length L as an interval is provided on the side edge on the first side 11 side, which is one side on the long side of the sewing article holder 10. The reference length L is set to a value set in the range of more than 10 mm and less than 50 mm, and a value that is an integral multiple of 5 mm. The reference length L is set based on a numerical value that is frequently used as a length of a sewing allowance, a bending allowance, or the like in a learning material for sewing training.

  In other words, the learning materials for sewing training that are currently on sale use only values that are integral multiples of the specific length as the length of the seam allowance or bending allowance to reduce the occurrence of measurement errors. Yes. For example, in many of the above learning materials, the length of the seam allowance or bending allowance is an integer multiple of 2 cm (20 mm) such as 2 cm, 4 cm, 6 cm, and 1.5 cm, 3.0 cm, 4.5 cm, etc. It can be classified into any of the teaching materials having a value of an integral multiple of 1.5 cm (15 mm). Accordingly, when the sewing material holder 10 corresponding to the former teaching material is used, the reference length L is set to 2 cm (20 mm), and when the sewing material holder 10 corresponding to the latter learning material is used, the reference length L is set. Set to 1.5 cm (15 mm). In the present embodiment, the reference length L is set to 2 cm (20 mm).

  Also, a numerical value representing a distance in centimeters from the end of the first side 11 to the corresponding main scale 20 is displayed near the tip of the main scale 20. Here, for the main scale 20 located on the first end portion 10a side of the first side 11 in the main scale 20, a numerical value indicating the distance from the first end portion 10a to the corresponding main scale 20 is displayed. Has been. For the main scale 20 located on the second end 10b side of the first side 11, a numerical value indicating the distance from the second end 10b to the corresponding main scale 20 is displayed.

  In the 1st edge | side 11, between the adjacent main scales 20, the sub scale 21 of 5 mm space | interval is provided. The sub-scale 21 is different in the shape of the scale line (specifically, forming the scale line more narrowly) and by not attaching a numerical value representing the distance from the end of the first side 11, Differentiation from the main scale 20 is achieved. Therefore, the main scale 20 is displayed so as to stand out from the sub scale 21.

  On the side edge on the second side 12 side, which is the other side on the long side of the sewing product holder 10, scales 22 are provided at intervals of 5 mm. In the vicinity of the tip of the scale 22 provided at a position where the length from the first end 10a is an integral multiple of 10 mm in the scale 22, there is a centimeter from the first end 10a to the corresponding scale 22. A numerical value representing the unit distance is displayed.

  Further, the length of the short side of the sewing product holder 10 is set to the reference length L. Therefore, the length of the short side of the sewing product holder 10 of this embodiment is 20 mm. Further, scales 23 with a 1 mm interval are provided on the side edges of the sewing product holder 10 on both short sides.

  Next, the operation of the sewing implement 10 of this embodiment will be described. Here, based on FIG.2 and FIG.3, it demonstrates as an example the case where the mark of the cutting line 32 is marked on the outer side of the finishing line 31 marked on the fabric material 30, ensuring the sewing allowance 33 of a predetermined width.

  As shown in FIGS. 2A and 2B, when the length of the sewing allowance to be secured is equal to the reference length L, one side of the long side of the sewing product holder 10 is overlapped with the finished line 31. The sewing tool holder 10 is placed on the cloth material 30 so that the width of the seam allowance 33 matches the short side of the sewing tool holder 10. Then, a line (broken line) is drawn along the other side of the long side of the sewing implement 10. As a result, the cutting line 32 is marked at a position away from the finished line 31 by the seam allowance 33 of the reference length L. Accordingly, the reference length L can be measured without reading the scale only by matching the width of the seam allowance 33 with the short side of the sewing workpiece 10. For this reason, it is difficult for erroneous reading of the scale.

  As shown in FIGS. 3 (a) and 3 (b), when the length of the sewing allowance 33 to be secured is a value that is an integral multiple of the reference length L, the sewing product is inserted so as to be orthogonal to the finish line 31. Put ten. Then, with the scale line of the main scale 20 corresponding to the length of the seam allowance 33 to be secured (4 cm in FIG. 3) superimposed on the finished line 31, a mark 32 a is formed along the short side of the sewing implement 10. wear. After the operation of attaching the mark 32a is repeated at predetermined intervals along the finish line 31, a line connecting the marks 32a is drawn. As a result, the cutting line 32 is marked at a position away from the finished line 31 by an integral multiple of the reference length L.

  Here, when the scale line of the main scale 20 is overlaid on the finish line 31, the sewing line 10 is formed transparent, so that the finish line 31 can be visually recognized through the sewing line 10. Therefore, the scale line of the main scale 20 can be easily overlapped with the finished line 31. Moreover, since the main scales 20 are provided at intervals of the reference length L, the adjacent main scales 20 are located apart from each other as compared with the conventional bamboo ruler scales provided at intervals of 1 mm or 5 mm. Yes. For this reason, it is difficult to make a mistake in the main scale 20 aligned with the finish line 31, that is, a mistake in reading the scale.

  When it is necessary to measure a length other than a value that is an integral multiple of the reference length L, a secondary scale 21 provided between the main scales 20 of the sewing implement 10, a scale 22 on the second side 12 side, and The scale 23 on the short side is appropriately used.

According to the present embodiment, the following effects can be obtained.
(1) A main scale 20 is provided on the first side 11 on the long side of the sewing product holder 10 having a belt shape with a constant width. The interval of the main scale 20 is a reference length L (however, the reference length L is an integer multiple of 5 mm) set in a range of more than 10 mm and less than 50 mm. According to the above configuration, when teaching is performed using a learning material for sewing training that uses many values that are integral multiples of the reference length L, it is difficult to make a mistake in reading the scale. Therefore, it becomes possible to easily perform the work of measuring and marking necessary dimensions. As a result, the burden on the instructor and the child receiving the instruction is reduced.

  (2) The length of the short side of the sewing implement 10 is set as the reference length L. When the dimension to be measured is equal to the reference length L, it is possible to measure the reference length L without reading the scale only by aligning the short side of the sewing tool 10. Therefore, it is possible to more effectively suppress the reading error of the scale.

  (3) A numerical value representing the distance from the first end portion 10a is attached to the main scale 20 located on the first end portion 10a side of the center of the first side 11 on the long side. And the numerical value showing the distance from the 2nd edge part 10b is attached | subjected to the main scale 20 located in the 2nd edge part 10b side rather than the center.

  According to the said structure, a reference | standard scale (zero scale) is provided in the both ends of the long side of the sewing implement 10. Thereby, for example, in the case of marking predetermined positions on both the left and right sides from a specific line, when marking on the other side after marking on one side, the sewing implement 10 is not reversed but left and right. The sewing implement 10 can be arranged at a position where the other side can be marked only by changing the reference scale used by sliding.

  (4) The sewing material holder 10 is formed of a transparent synthetic resin material. According to the above configuration, when the sewing article holder 10 is placed on the cloth material 30, the end of the cloth material 30, the lines written on the cloth material 30, and the like can be visually recognized through the sewing article holder 10. Therefore, the scale lines of the scales of the sewing material holder 10 can be easily overlapped with the ends of the cloth material 30 and the lines drawn on the cloth material 30.
