The invention relates to a locking hinge for a tubular frame, and provides a number of variations of the locking hinge for the tubular frame. One variation of the locking hinge for the tubular frame may include a first tubular frame and a second tubular frame connected by a hinge for movement relative one another between folded and unfolded positions; a threaded shaft rotatably mounted in the first tubular frame to selectively rotate and advance from the first tubular frame and rotate and withdraw into the first tubular frame; an internally threaded nut mounted in the second tubular frame; and a motor mechanism for rotating the threaded shaft in one direction to thereby advance the threaded shaft into threaded engagement with the internally threaded nut when the first and second frame are in an unfolded position to lock the first and second frame at the unfolded position, and for rotating the threaded shaft in another direction to withdraw the threaded shaft from the internally threaded nut so that the first and second tubular frames may be moved from the unfolded position to the folded position.
