<p>A transfer board with at least a pair of elongated elements interconnected by means of at least one hinge allowing the elongated members to fold on each other when not in use, wherein the said hinge forms a rigid joint between the said elongated members when the said members are unfolded for use; and wherin the location of the hinge is offset to one side of the joint centerline such that the rigid joint formed between the connecting parts is not primarily-dependent on the mating surfaces perpendicular to the long axis of the said elongated members and forming an alternative primary load path between the soffit of the first elongated member and the cooperating upper surface of the projecting connector of the second elongated member. In this respect the gap between the elongated members remains constant under normal use and eliminates a possible pinching point.</p> |
