Title:
JOINT FOR COLLAPSIBLE STRUCTURES
Document Type and Number:
WIPO Patent Application WO2000024479
Kind Code:
A9
Abstract:
A joint having a socket portion facilitates forming a collapsible structure. The joints can be formed as corner joints or straight joints and any number of members may be connected to the joints. The socket portion of the joint accommodates a movable member which has multiple degrees of motion. The movable member is connected with a threaded or otherwise twistable connection to the rod of a heim joint which rotates on a roll pin. The movable portion moves in and out of the socket portion to erect and collapse the structure. Frame members are attached to the fixed and movable portions of the joint. A cover plate on the joint assists in aligning the movable portion into the proper position so that the erect structure is stable.
