Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention allows a tooth-shaped figure to be easily drawn by tracing a predetermined figure formed on a plate with a desired writing instrument. Regarding the tooth template that has been made possible.

<<Prior art>> As shown in FIGS. 8 and 9, the conventional tooth template has a pattern b of a desired tooth shape on a plate a.
It has been punched out as a whole.

Therefore, according to the above-mentioned known tooth pattern template, by placing the template on a paper surface or the like and tracing along the inner side e of the shape shape b using a rod ring or other writing instrument, the shape shape b can be drawn. The same tooth-shaped figure is drawn on paper, etc., but since the template is a die cut out of the figure type b as described above, the ridges c and troughs d are drawn around the periphery as shown in the example. When tracing the trough d along the inner edge e, since the plate a is thin, there may be lines that protrude inward or in the left-right direction depending on the force of the writing instrument, especially as illustrated by the broken line in FIG. c' and d' may be unintentionally extended, the protruding corner f where the peak c and the valley d intersect may be difficult to trace accurately, and the punching of the inner edge e may cause the plate a to Since the number of defective portions g increases, the strength as a whole becomes weaker and there are problems such as being more likely to be damaged.

<<Problems to be Solved by the Invention>> As a result of studies in view of the above-mentioned problems, the present invention has been designed to have a structure in which only the peaks or valleys are removed from the surrounding area when forming a tooth mold. Therefore, only the punch holes are scattered, and all you have to do is trace along the inner edges of the punch holes to avoid worrying about them sticking out.As a final step, draw the peaks as described above. Alternatively, by making a part of the valley continuous by drawing a line using a ruler, a predetermined figure can be drawn accurately and beautifully in a short time, and the strength of the plate can be improved to make it easier to use. Its purpose is to kill.

<<Means for Solving the Problems>> In order to achieve the above-mentioned object, the present invention provides a plate with notches in the peaks or valleys of a desired tooth shape,
It is an object of the present invention to provide a tooth template characterized in that a required plurality of punching holes are arranged in rows and dots.

<<Embodiment>> The present invention will be described in detail below based on the embodiment of the drawings. As shown in FIGS. 1 to 7, the plate 1 includes a thin plate made of plastic or other arbitrary material as is known. used.

The tooth template according to the present invention can be formed, for example, as follows.

That is, first, a predetermined figure 2 is drawn on the plate 1, and the figure 2 illustrated in FIG.
is drawn at a desired pitch P. On the other hand, in the embodiment shown in FIG. 2, the trough 4 is drawn at a predetermined pitch on the inner circumference of the elliptical line L1.

In FIG. 1 above, punching means or the like is applied to the corresponding part of the plate 1 for each mountain part 3,
The punch holes 3a, 3b, etc. as shown in FIG. 3 are opened intermittently, and each valley 4 in FIG.
If you punch out the hole 4 as shown in Figure 4,
a, 4b, . . . are intermittently dotted with openings.

In other words, if each peak 3... is missing, each valley 4 is left; on the other hand, if each valley 4... is missing, each valley 3... is left. A template is formed.

Further, as shown in FIGS. 1 and 2, a plurality of graphic molds 2, 2'2", etc. of different sizes can be formed concentrically on one plate 1, and The one in Figure 5 is not based on the oval line L1,
A punch hole 3a protruding from the outer periphery of the circular line L2,
3a... are scattered.

To draw a tooth pattern on a paper surface using the above-mentioned structure, first place the plate 1 on the paper surface, hold the plate 1 in place so that it does not move, and use the desired writing instrument to make the above-mentioned punch hole. 3a... or 4a..., but in this case, if the crest 3a... is formed by punching, trace along one side edge 3b of the punched hole 3a corresponding to the bottom of the ridge 3. By tracing along the other three edge sides, each chevron 3c, 3c, etc. is drawn as shown in Figure 6A.

Also, in this case, as shown in Fig. 2, each valley portion 4... is punched out to form punch holes 4a, 4b...
One side edge 4 of the punch hole 4a corresponding to the top of the valley 4
By tracing along the other three edge sides excluding point b, draw each chevron 4c, 4c, etc. as shown in Fig. 7A.

As described above, each chevron 3c shown in FIG. 6A,
3c..., then remove the plate 1 from the paper and use a separately prepared regular ruler to draw out the part corresponding to the bottom surface 4 of the trough 4, as shown in the figure B. This completes the tooth pattern 2a.

On the other hand, when using the punch holes 4a as described above, after removing the plate 1 from the paper surface, the tooth pattern 2a can be drawn by drawing a line at the portion corresponding to the top of the crest 3 as shown in FIG.

<<Effects of the Invention>> The tooth template according to the present invention is constructed as described above, and the punching holes 3a and 4a are removed, so when tracing along the inner edge thereof, there is no risk of the writing tool protruding. After tracing the required part of each chevron 3c, 3c... or each chevron 4c, 4c..., you can draw a tooth pattern by drawing lines on the remaining part with a ruler, etc., making the entire operation quick and efficient. It can be completed with a beautiful finish.

In addition, since the entire tooth mold is not punched out in a large size as in the past, it is strong and not only hard to break at the top but also hard to deform, making it possible to draw more reliable shapes. It is also possible to concentrically and complexly form graphic molds 2 of different sizes on a single plate 1.
