Triangular trestle to support table or shelf

摘要

The trestle is a symmetrical polyhedral with six faces and it has two planes of support which are isosceles triangles (BBC', DCC'). These support the table at two different heights (AD, AB). The trestles can be assembled from four planes or have nine corners joined together. The trestles can be made from metallic or plywood plates which are assembled and they can be piled up. They can be made from sections joined by junctions made of moulded material or from metallic tubes with three bent pieces or nine straight pieces joined together.
