A pivot joint (1) is shown for pivotally connecting two members (3, 5), the first (3) of which is of a channel section at least in the area of the joint and is adapted to receive the second member (5) within the channel. The joint (1) comprises a joint body (7) of substantially channel cross section having first connection means (9) in opposite internal side walls (17) of the channel for connection to the second member (5)to be pivoted which is intended to lie within the channel of the joint body (7) and second connection means (11) in opposite external side walls (21) of the channel, aligned with the first connection means (9) and for connection to the first member (3) to be pivoted which is intended to lie, at least in part, around the outside of the channel of the joint body (7). The two connection means (9, 11) comprising trunnion members (15, 19) of which at least one pair (19) is of frusto-conical shape. <IMAGE> |
