Patent ID: 7118309

Claim:
A component for spatial grid supporting systems which holds filler material, comprising: a body frame having at least one front longitudinal member extending along a front side of the component and at least one cross member extending from a rear surface of the at least one front longitudinal member and at an angle relative to a front surface of the front longitudinal member, each front longitudinal member having a polygonal cross section and generally planar front and rear surfaces, and extending in a direction normal to a frame plane determined by said each front longitudinal member and the at least one cross member; wherein the front and rear surfaces of the at least one front longitudinal member form an angle between 2° and 15°, said angle opening towards a bottom of said longitudinal member and the front surface of each front longitudinal member is sloped towards an interior of the body frame from a bottom portion to the top portion of the front surface at an angle between 2° and 15° relative to the normal direction.
