Abstract: A support frame is provided to be mounted to one or more support platforms having respective holes defined therein. The support frame comprises an elongate rigid column having a longitudinal axis extending from a proximal end to a distal end opposite the proximal end, at least the distal end and an associated portion of the elongate rigid column configured to extend through the one or more support platform holes. A platen bracket is connected to the elongate rigid column nearer the proximal end than the distal end, and a support platen is connected to the platen bracket. At least one flange is positioned along the elongate rigid column nearer the distal end than the proximal end, and extends transversely from the longitudinal axis of the elongate rigid column. The one or more flanges are configured to interface with at least one of the one or more support platforms.

Abstract: A support frame may be mounted to a corresponding support platform. The support frame may include an elongate rigid column including a proximal end and a distal end opposite the proximal end. A platen bracket may be connected to the elongate rigid column nearer the proximal end than the distal end. A support platen may be connected to the platen bracket. A flanged sleeve may be coaxially received on the elongate rigid column nearer the distal end than the proximal end. The flanged sleeve may include a sleeve portion slidably received on the elongate rigid column and a mounting flange extending from the sleeve portion. The mounting flange may be configured to interface with the support platform. A guide sleeve may be coaxially received on the elongate rigid column between the platen bracket and the flanged sleeve. The guide sleeve may be configured to maintain the platen bracket and the flanged sleeve in a spaced apart orientation when the support frame is mounted to the corresponding support platform.
