Abstract:
A crutch has a joint structure, and the crutch includes a stationary section supported on a floor at a lower end of the stationary section, and extending from a lower portion to an upper portion thereof; and a rotary section coupled to the stationary section so as to be rotatable relative to the stationary section with respect to a rotational axis provided at the upper portion of the stationary section. The rotary section is configured by coupling a hand grip part for supporting a wearer's hand in a state where the wearer wears the crutch and a forearm part supporting a forearm of the wearer.

Claim (Index 1):
A crutch having a joint structure, the crutch comprising\n a stationary section supported on a floor at a lower end of the stationary section, and extending from a lower portion to an upper portion thereof; and a rotary section coupled to the stationary section so as to be rotatable relative to the stationary section with respect to a rotational axis provided at the upper portion of the stationary section, wherein the rotary section is configured by coupling a hand grip part for supporting a wearer's hand in a state where the wearer wears the crutch and a forearm part supporting a forearm of the wearer,. further including a locking mechanism configured to inhibit a relative rotation between the stationary section and the rotary section at a preset fixed angle corresponding to a state in which the wearer wears the crutch in a standing posture, wherein the locking mechanism comprises a protrusion formed to be protruded outward from the stationary section and a through hole formed by penetrating the rotary section to correspond to a shape of the protrusion, such that as the protrusion passes through the through hole, a relative rotation between the stationary section and the rotary section is inhibited, and wherein the protrusion and the through hole are located on the rotational axis between the stationary section and the rotary section, and the protrusion is formed in a column shape having a triangular cross section.
