Abstract: An interlocking building block is disclosed primarily as a replacement for glass blocks or tiles. The block has front and rear walls or surfaces and intermediate peripheral end walls that intersect at an angle. At least two intersecting end walls have tongues and grooves adapted to mate with corresponding grooves and tongues on adjacent blocks and these tongues and grooves on the intersecting end walls each have interlocking means to engage complimentary interlocking means on adjacent blocks to prevent sliding movement therebetween, thus giving a four-direction interlock between the blocks.

Abstract: An improved metal pallet is shown having elongate deck members defining a load bearing surface and transverse stringer members to support the deck members. The stringer members are generally U-shaped having generally upright laterally resilient sides defining longitudinally spaced-apart, transverse openings located adjacent to the upper marginal edges of the sides. The ends of the deck members pass through the stringer member openings. The deck members have longitudinal downwardly and outwardly disposed laterally resilient sides defining opposed pairs of parallel slot openings. The longitudinal spacing between these slot openings is different than the normal transverse spacing between the stringer sides, so that upon assembly of the pallet the stringer and deck member sides are laterally deflected; the peripheral edges of the stringer openings are located in the slot openings, and the deck members and stringer member are biased into mutual engagement by the lateral deflections of the respective sides.

Abstract: A pallet or skid is disclosed for use in material handling. The pallet, preferably formed of metal, may be rigidly assembled or disassembled without the use of welding or fasteners, or the like. The pallet has a plurality of longitudinal deck panels for horizontal parallel location to form a load bearing surface. The deck panels have longitudinal resilient edge portions defining a plurality of spaced-apart slots. A plurality of spaced-apart stringer members are provided for transversely engaging the deck members, with the deck members passing through openings in the stringer members. The stringer member openings are dimensioned to provide retaining portions, so that upon transverse deflection of the deck member edge portions, the deck members may slide through the stringer member openings until the slots register with the retaining portions causing the deck members to snap and lock into position in the stringer members.
