【発明の詳細な説明】
本発明は、例えば、非常口ドアの蝶番、あるいは掛金等
の材料に用いて好適の低融点合金に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low melting point alloy suitable for use as a material for, for example, hinges or latches of emergency exit doors.
一般に低温で容易に溶融する低融点合金は種々知られて
いるが、それらの多くは、融点が比較的高い。なかには
体温で溶けるようなものもあるが、それは水銀を含んで

った。Generally, various low melting point alloys that melt easily at low temperatures are known, but many of them have relatively high melting points. Some materials melt at body temperature, but they contain mercury and have the disadvantage of being mechanically fragile. For this reason, all of them are unsuitable as materials for, for example, hinges or latches of emergency exit doors that take all safety measures into consideration in the event of a fire.
従来よう、これら火災の安全対策全考慮した非常口ドア
