Abstract
Abstract A wall of building blocks, each block being in the form of a parallelepipedon having corrugated or sawtooth shaped upper and lower surfaces, the corrugations or teeth of one surface extending perpendicular to the corrugations or teeth of the other. Two opposite ends of the block may be provided with parallel ribs and slots in asymmetric relation so that when two such blocks are arranged end-to-end a slot in each block accommodates a rib of the other block. Some blocks may have one flat end and a slot in one of its sides to accommodate the rib of another block when the two blocks are arranged to form a corner. All the blocks have cavities extending completely through them. A plurality of such blocks can be arranged end-to-end and one above the other, with the corrugations or sawteeth of each block meshing with the corrugations or sawteeth of another, to form a wall, and mortar or concrete is then poured into all the aligned cavities of the blocks.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
218 words
A wall composed of building blocks arranged end-to-end and one above the other, each building block having the general shape of a right parallelepipedon including front and rear sides, two ends, a top, and a bottom, said top being formed with continuous undulations each of which extends in a direction from said front side toward said rear side, said bottom being formed with continuous undulations each of which extend in a direction perpendicular to said top undulations, the contour of all said undulations being identical so that the bottom undulations of the block can mesh with the top undulations of another similar block, there being twice as many top undulations as bottom undulations on said block, each end of the block presenting a slot and a rib extending between said top and bottom, said slot and rib on each end being in positions reversed with respect to the slot and rib on the opposite end so that when two such blocks are placed end-to-end, the ribs in the two adjacent ends are accommodated by the slots in those ends, and at least some of said blocks having slots in their sides for accommodating the rib presented by the end of another block when two blocks are arranged perpendicular to each other to form a corner of the wall.

A wall composed of building blocks arranged end-to-end and one above the other, each building block having the general shape of a right parallelepipedon including front and rear sides, two ends, a top, and a bottom, said top being formed with continuous undulations each of which extends in a direction from said front side toward said rear side, said bottom being formed with continuous undulations each of which extend in a direction perpendicular to said top undulations, the contour of all said undulations being identical so that the bottom undulations of the block can mesh with the top undulations of another similar block, there being twice as many top undulations as bottom undulations on said block, each end of the block presenting a slot and a rib extending between said top and bottom, said slot and rib on each end being in positions reversed with respect to the slot and rib on the opposite end so that when two such blocks are placed end-to-end, the ribs in the two adjacent ends are accommodated by the slots in those ends, and at least some of said blocks having slots in their sides for accommodating the rib presented by the end of another block when two blocks are arranged perpendicular to each other to form a corner of the wall.
Claim 3
Dependent Claim
20 words
A wall as defined in claim 1 wherein said undulations of each block have the shape of a sine wave.
Claim 4
Dependent Claim
17 words
A wall as defined in claim 1 wherein said undulations of each block have a sawtooth shape.
Claim 5
Dependent Claim
18 words
A wall as defined in claim 1 wherein said front and rear sides of each block are flat.
Claim 6
Dependent Claim
31 words
A wall as defined in claim 1 wherein the blocks are made of a material selected from the group consisting of brick, clay, concrete, wood, plastic, glass, metal, and combinations thereof.
Claim 7
Dependent Claim
17 words
A wall as defined in claim 1 wherein said bonding material is one of mortar and concrete.
