Abstract
(EN)
ABSTRACT A pivot joint comprising a first member of generally channel section at least in the region of the joint a second member to which the first member is to be pivotally connected and which is adapted to lie at least partially within the first member in the region of the joint and a joint body adapted to lie around the second member while being largely contained within the channel of the first member . The channel section of the first member has at least one wall 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 is shaped exteriorly to complement the interior of the channel and is provided with a pair of external trunnions aligned with corresponding apertures in the first member and with means for attaching the joint body to the second member . The materials of the joint and the arrangement of the parts are such that the sides of the channel of the first member can flex sufficiently to allow the second member together with the joint body to be snapped into the channel of the first member , the trunnions of the joint body being thereby inserted into the apertures in the first member to complete the joint.
