LEG SUPPORT AID HAVING ROTARY-TYPE AUTOMATIC JOINT LOCKING DEVICE AND METHOD FOR OPERATING SAME

摘要

The present invention relates to a leg support aid having a rotary-type automatic joint locking device, and to a method for operating same. The present invention comprises: a removable upper brace (100) that is disposed at the upper portion of a leg joint in order to support the leg; a removable lower brace (200) that is disposed at the lower portion of the leg joint in order to support the leg; and a joint locking unit (300) that selectively restricts the pivoting of the braces and is configured of a rotary cylinder (330) connected to the side surface of the upper brace (100) and/or the lower brace (200) in the case where the upper brace and the lower brace (200) pivot about the leg joint, a partition wall lever (333) that is fixed to the upper brace and divides the rotary cylinder into two spaces filled with a fluid, a connection pipe (335) connected to the two spaces in the lower portion of the rotary cylinder (330) so as to move the fluid, and an actuator (350) that blocks the movement of the fluid through the connection pipe (335). According to the present invention, a simple and convenient structure is used to selectively restrict or block the pivoting of the leg joint by user selection and the joint can be fixed and released automatically and at various angles, and thus the body can be stably supported in a state where standing is required with the leg joint being bent.
