Abstract

Abstract A portable, lightweight, board-gripping support for a conventional board includes four rectangular, tubular pieces. The four pieces are configured and connected to form generally an A-shape in a single plane. Bar members form the upper and lower cross members of the A-shaped support. Opposing surfaces of the bar members are substantially planar, oriented orthogonal to the plane of the A-shaped support, and spaced apart by a distance greater than the thickness of the board such that the support forms an obtuse angle β with the board when the edges of the opposing surfaces of the bar members contact the board. The angle β is between 102° and 140°. When the board spans a pair of supports, and a downward loading force is applied to the board, the edges of the bar members create indentations in the board which resist relative sliding movement between the board and the support.
