Description

[Detailed description of the invention] Technical field The present invention relates to a cutting ruler. Specifically, the invention relates to a cutting ruler used for cutting cylindrical or bag-shaped cloth into a single string.

Conventional technology Until now, there was no simple tool available for cutting a tube-shaped or bag-shaped piece of cloth into a single string, and at home, people had to cut it into a single string using scissors or a cutter knife by eye. . For this reason, the width of the string may not be uniform. Furthermore, when using stretchable cylindrical or bag-shaped cloth, cutting work is extremely troublesome.

For this reason, there is a demand for a simple tool that can obtain a string of the desired uniform width, and with such a tool, it is possible to turn a worn-out tube or bag of cloth into a single string. Therefore, it is possible to use resources effectively.

Purpose of the invention The purpose of the invention is to provide a cutting ruler that has a simple structure and is easy to handle, which cuts a cylindrical or bag-shaped cloth into a single string of uniform width.

Structure of the invention The structure of the invention to achieve the above purpose is as follows:
A large number of notched grooves are bored in the transverse direction of a rectangular board at predetermined intervals and the length is shorter than the width in the transverse direction,
A comb-shaped plate material having a comb-teeth shape, and a removable member having a U-shaped cross section and an opening having a thickness substantially equal to the thickness of the comb-teeth shaped plate material, and covering the tips of all the comb-teeth shaped parts of the comb-teeth shaped plate material. The gist of this invention is a cutting ruler for obtaining a string from a tubular or bag cloth, characterized by a comb-teeth cover.

Embodiments The present invention will be described below with reference to embodiments and drawings. 1 to 6 show an embodiment of the cutting ruler. In Figures 1a, b, and c, 1 is a rectangular comb-shaped board made of lightweight board material such as plastic or aluminum, and is spaced at equal intervals in the transverse direction, and the width in the transverse direction is short. A large number of long notch grooves 2 are bored to form a comb-teeth shape.
In this example, the length in the vertical direction is 62 cm, the width is 11 cm,
In a plate material with a thickness of 3 mm, cutout grooves 2 are bored at 33 locations at about 4/5 of the width, 34 comb teeth 3 are provided, and the four corners of the comb-shaped plate material 1 and the tips of the comb teeth 3 are formed. is rounded.

4 is made of the same material as the comb-like plate material 1;
Narrow rectangular board 3 as shown in figures a, b, c
The comb-teeth 3 of the comb-teeth-shaped plate 1 are glued together and have a U-shaped cross section and the diameter of the opening is approximately equal to the thickness of the comb-teeth-shaped plate 1.
It is a removable comb-teeth cover that is long enough to cover all the tips of the comb. Its length is made slightly longer than the length of the comb-like plate 1 so that it can be easily attached to and removed from the comb-teeth 3.

The cutting ruler of this embodiment is composed of the comb-teeth shaped plate material 1 and the comb-teeth cover 4 described above, as shown in FIG. Furthermore, as shown in FIG. 3b, the comb cover 4 can also be attached to cover the back of the comb plate 1. Regardless of whether it is attached to the tip or the back of the comb teeth 3 of the comb tooth shaped plate 1, its end face is represented as shown in FIG. 3c.

Next, how to use the cutting ruler of this embodiment will be explained.

First, as shown in Fig. 3a, a comb-teeth cover (hereinafter simply referred to as the cover) 4 is attached so as to cover all the tips of the comb-teeth 3 of the comb-teeth shaped plate material (hereinafter simply referred to as the plate) 1. . This is to prevent the stockings from getting caught on the comb teeth 3 when covering this embodiment with stockings. After that, put the stockings 5 on top, as shown in Figure 4a. Then, the cover 4 is removed from the comb teeth 3 side of the plate material 1, and the cover 4 is attached to the back of the plate material 1. At this time, it may be removed from the plate material 1, but since it will be attached again to the comb tooth 3 side in a step to be described later, it is more convenient to attach it to the back. Furthermore, as shown in FIG. 4b, a cut is made in the stocking 5 along the cut groove 2 using scissors or a cutter knife. Then, the cover 4 is removed from the back of the plate 1 again and attached so as to cover all the tips of the comb teeth 3 of the plate 1. At this time, a part of the stocking that has come off the comb teeth 3 and bit into the notch groove 2 is removed from the notch groove 2 by the cover 4. Further, as shown in FIG. 4c, the stockings 5 are turned and moved by hand to bring them into the state shown in FIG. 4c. Then, as shown in FIG. 5a, a cutting line 6 that connects the tip of the comb teeth 3 of the plate material 1 or the cut portion of the stocking 5 that appears on the back is shifted by one position.
For example, the stockings 5 are cut along a thick solid line connecting the cutting tips 7 and 8. Also, Figure 5b
Remove the cut stockings from the cutting ruler as shown in the figure below, and cut off both ends of the stockings to create a single string with approximately uniform width.

As mentioned above, the following points can be mentioned as the effects obtained by using the cutting ruler of this embodiment.

By using stockings, resources can be used effectively. Further, this embodiment has a simple structure, and it is possible to cut elastic stockings or the like into a single string of substantially uniform width by simple operations.

In addition, the width of the comb teeth 3 can be set to a desired width so that the string can be made to a desired width, and in order to prevent a part of the stocking from shifting from the comb teeth 3 and biting into the notch groove 3, the comb teeth 3 can be set to a desired width. The tip of 3 may be wavy, serrated, concave, or knurled as shown in FIGS. 6a, b, and c, but these are not limited to the present embodiment.

Effects of the invention The cutting ruler of the invention is composed of a comb-shaped plate and a comb-shaped cover that is detachably attached to the plate.

Therefore, with such simple tools and simple operations, it is possible to make a string from a tube-shaped or bag-shaped cloth, and this string can be used to make various types of woven and knitted fabrics. It becomes possible. Note that by appropriately selecting the width of the comb teeth, a string of desired width can be made.

By using tube-shaped or bag-shaped cloth such as old stockings, resources can be used effectively.
