Patent ID: 8490342

Claim:
A support means for engaging a batten, joist or elongate member having a constant width, the support means including a rotatable plate, and further defining means for engaging the support means with a support structure, selected from a group comprising pedestal jacks and pedestal supports, in a manner which allows the support means to be rotated about an axis, the support means further including two opposed upstanding walls defining a gap therebetween for receiving the batten, joist or elongate member, the walls being disposed on either side of the axis and extending from a centermost position closest to the axis to a distal end farthest from the axis, the walls being at least partly convex, wherein the gap between the walls measured in a direction perpendicular to tangents to the walls decreases from the centerrnost part of the walls to the distal end of the walls, so that for a joist batten or elongate member having a predetermined width and positioned between the walls, rotation of the support means about the axis in one sense causes the walls to tend to abut edges of the joist and in the opposite sense to tend to move away from the edges of the joist; the two opposed upstanding walls including through apertures to receive fasteners including nails or screws, and wherein each wall includes a straight portion which extends from the centremost portion of the walls in an opposite direction to the convex portion of the walls, the straight portions being parallel to each other.
