F/G./ F/G.6

BUILDING BLOCK GAME An object of my invention is to provide a novel building block game in which various blocks have a different center of gravity so that it requires skill to stack the blocks one upon the other.

Another object of my In building block game which can be formed of various materials. Also they are so shaped that they will interlock with one another to provide a vertical structure.

Other objects and advantages of my invention may appear from the accompanying drawings, the subjoined detailed description and the appended claims.

In the drawing:

FIG. 1 is a plan view of my building block game enclosed in a box or container.

FIG. 2 is a perspective view of first one of the blocks.

FIG. 3 is a perspective view of a second one of the blocks.

FIG. 4 is a perspective view of a third block.

FIG. 5 is a perspective view of a fourth block.

FIG. 6 is a perspective view of the uppermost block.

FIG. 7 illustrates the vertical assembly of the various blocks.

Referring more particularly to the drawing: Numeral 1 indicates a box or container in which the variousshaped blocks may be placed for storage, shipping or the like. A lowermost tier of the blocks 2 is formed with two upwardly extending wings 3 to form a series of blocks as shown in FIGS. 1 and 2. One of the blocks 2 becomes the lowermost foundation block and all subsequent blocks rest on this one when the blocks are arranged to define a column. The second series of blocks 4 is also provided with a single upwardly projecting offset inverted L-shaped wing 5, which wing fits against a block 4 as shown in the lower portion of FIG. 7. Again, as shown in FIG. 7, the block 6 is identical to the block 2 and rests against the wings 5 as shown. Still another block 7 is identical to the block 2 and 6. This block 7 in turn supports a pair of blocks 8 and 9 which are identical to the block 4. The projecting wings of this block interlock as shown in FIG. 7 and thus support the column to this point. Still another block 10 is identical to the block 2, and the wings ll of this last-named block engage and grip the blocks 8 and 9 again as shown in FIG. 7. An additional block 12 is provided with an upvention is to provide a novel right L-shaped wing 13 which rests on the block 10 as shown in FIG. 7. The block 14 again is identical to the block 2 and supports a block 15 that includes an inverted L-shaped wing 16 that is aligned with the block as shown in FIG. 7. The block 16 is identical to the block 15 as shown in FIGS. 4 and 7. The block 17 is identical to the block 16 and rests thereon as shown in FIG. 7. The final block 18 rests on top of the block 17 and serves as a cap when it is the ultimate or winning position at the top of the blocks that define a column.

Having described my invention, I claim:

1. A building block game in which the blocks comprising the same are adapted to be stacked laterally to define a column in which a portion of the blocks interlock and extend transversely therefrom, said game comprising: a plurality of rectangular blocks in which a first portion thereof includes V-shaped wings that extends outwardly from flat surfaces thereof, a second portion of said blocks that include inverted L-shaped members that project from flat surfaces thereof and are partially offset from said blocks, a third portion of said blocks that include inverted L-shaped members that project from flat surfaces thereof and are axially aligned with said blocks, and a fourth portion of said blocks that include L-shaped members in abutting contact flat surfaces thereof, with one of said blocks of said first portion serving as a base for said column with said V-shaped wing in upwardly extending position and said blocks defining said first, second, third and fourth portions being stacked one upon the other to rest on said V-shaped wings to define said column and at least a part of said first, second, third and fourth portions of said blocks stacked on said V-shaped wing of said block that serves as a base interlocking with one another to extend horizontally from said column.

2. A building block game as defined in claim 1 which in addition includes a block different in shape from those blocks that define said first, second, third and fourth portions, said block serving as a cap when said column is completed.

3. A building block game as defined in claim 2 in which said block that serves as a cap includes a rectangular portion that has an inverted V-shaped member secured to a fiat face thereof.
