Claims

[Scope of claim for utility model registration] Parts made of rigid materials ■, ■, ■, ■, with the center of each pin hole (at this time, the center of the pin also coincides with the center of the hole) A, B , C, and D (see Figure 1) form a parallelogram ABCD. A is one side of a parallelogram
From one end A of D, pin the part (■) into the slide hole (■) of the part (■) as shown in Figure 1 (position E). However, the pin can slide through the hole. In the same way, EF, FGSGH
,... and parts■. Alternately pin the required number of ■ to the slide holes 〇. Attach a needle to the tip of part ■ or make it sharp. As described above, we created a line segment equal divider that created a parallelogram, derived the triangle congruence conditions, made the intervals of DE, EC1, etc. equal, and made the intervals of their extensions, IJ, JK, etc. equal.
