초록 ▼

The disclosure relates to a crutch which is readily disassembled into a plurality manageable components which can be conveniently tucked away when not in use. The components can be easily adjusted to accommodate persons of different heights. A significant safety feature of the disclosure is the fact that each of the two release subassemblies is provided with a release pin sleeve that ensures a quick and efficient release of the release pin and subsequent re-engagement without the release pin hanging-up and thereby preventing injury to the user. A first embodiment discloses the height adjusting support member receiving both the upper and lower support members therein, while the second embodiment discloses the height adjusting member receiving only the upper support member therein with the lower support member receiving the height adjusting member therein.
