History of Springs
Etymology of the word "spring"
According to the multiple Japanese dictionaries, the Japanese word for spring, "bane", originated from "haneru", meaning to bounce or rebound.
There is another theory which hols that "bane" arose out of the words "joue" or "hane" appearing in "Shogenjikō setsuyōshū" (Collection of Abridged Chinese Characters) during the Genroku period. "Kusari-kata-bira" (chain mail) and "kusari-juban" (chain singlet) were undergarments worn by warriors going into war. Having nail lines woven into a mesh pattern, these garments were endowed with some elasticity. Since these garments deflected (haneru) sword and spear thrusts, the theory goes that the old word of "bane" (spring) originated out of this.
Various Chinese characters have been used to express "bane" (spring), however, the origins are unclear. Having said that, in "Karakuri Zui" written by Yorinao Hosokawa in 1796, springs are described as "hajigane" or "hajikigane", while in the manuscript "Kiban Ki" written by Kunitomo Tohei Noue, a gunsmith in 1819, springs are described as "hashikigane", while in the Inoue school artillery tradition, springs were written as "hajikigane". Therefore, "hajigane" and "danjikane," which denote independent parts, were applied to "danki," and "hajikigane" was connected to "haneru" (springing), which may have led to the word "bane" (spring). This is now the leading theory concerning the origin of the word "bane" (spring).
