A pivot joint for pivoting together first and second members (11, 12), at least the first (11) of which is of channel section at the joint, and the second (12) of which is adapted to seat within the first (11) comprises a joint body (13) of generally channel section adapted to seat within the first member (11) and to receive the second member (12) therewithin. The joint body (13) has a pair of inwardly extending trunnions (15, 16) each provided with aligned bores (19, 20) , and each of said trunnions (15, 16) being adapted to cooperate with apertures (17, 18) in the second member (12) therewithin. The aligned bores (19, 20) through said trunnions (15, 16) are adapted to be aligned with apertures (21, 22) in the first member (11). A pin (14) is adapted to extend through the apertures (21, 22, 17, 18) of the first and second members (11, 12) and through the bores (19, 20)of the trunnions (15, 16) of the joint body (13). The pin (14) is retained in the bores (19, 20) of the joint body (13) by positive engagement of portions of the pin (14) with inwardly directed resilient collars (23, 24) on the trunnions (15, 16) of the joint body (13). <IMAGE> |
