ABSTRACT:
Blocks which can be used for assembling easily and inexpensively a piece of furniture or a part of a building, such as a table, stool, gate or arch. Each block comprises a molded body of a polyolefin foam having a rectangular, circular, oval or polygonal cross-section. The body has a pair of opposite surfaces of which one is provided with a plurality of regularly spaced apart holes, while the other surface is provided with a plurality of regularly spaced apart projections of which each can be fitted into one of the holes of another block. At least one bore extends through the body between the opposite surfaces thereof. The blocks are so light in weight and easy to handle that any assembly thereof can easily be dismantled for rebuilding another assembly having a different shape or structure. They are also highly resistant to water and are, therefore, suitable for building any assembly for outdoor use.
