Title
(EN) Pivot joint
Abstract
(EN)

A pivot joint comprising a first member (1) of generally channel section at least in the region of the joint, a second member (2) to which the first member (1) is to be pivotally connected and which is adapted to lie at least partially within the first member (1) in the region of the joint and a joint body (4) adapted to lie around the second member (2) while being largely contained within the channel of the first member (1). The channel section of the first member (1) has at least one wall (7) at an obtuse angle to the base of the channel so that the channel has a wider mouth than the base, the cross section of the channel being trapezoidal. The joint body (4) is shaped exteriorly to complement the interior of the channel and is provided with a pair of external trunnions (54,56) aligned with corresponding apertures (12,13) in the first member (10) and with means (62,64) for attaching the joint body (4) to the second member (2). The materials of the joint and the arrangement of the parts (1,2,4) are such that the sides of the channel of the first member (1) can flex sufficiently to allow the second member (2) together with the joint body (4) to be snapped into the channel of the first member (1), the trunnions (54,56) of the joint body (4) being thereby inserted into the apertures (12,13) in the first member (1) to complete the joint.
