Jangkirana, a corrugated paper headwear for night-time use.
Ever thought that corrugated paper could be turned into a helmet without using adhesive and fully relying on folds?
The ring part also has a belt to accommodate the differences in the varying user head circumference!
This helmet is made of three (3) parts: the ring that comes in contact with the head (also with the flap to cover the user's nape from night winds), the shell part, and the flashlight compartment. No adhesive was used. Everything comes from fold and locks. The neatness of the design comes from an accurate calculation using simple trigonometry.
Jangkirana. 2022. The design pattern is still available. Contact me and I would happily send you the details for free but only for academic purpose.
Thank you.
