BACKGROUND OF THE INVENTION
Construction Blocks have been around a long time; they are generally made of concrete and have vertical holes extruded through them. Another common Construction Block is the brick which may or may not have holes extruded through. In general coring of these blocks to conserve material is through the top and bottom and they are connected together by applying mortar between blocks.
BRIEF SUMMARY OF THE INVENTION
The Construction Block Lock deals with a method to build block walls without the use of mortar by inserting a separate part between the bottom of a block and the top of the block it is resting on that fits the cores in the blocks holding the blocks in alignment. Assembly, disassembly and reassembly is clean and simple; essentially a stacking operation. For temporary assemblies and shipping no additional treatment other than stacking would be necessary and in some cases for permanent assemblies may not be either.

DESCRIPTION OF INVENTION
The Construction Block Lock system invention is comprised of a first part, a square block cored from top to bottom with the perimeter of the core centered on the block; a second block, a two square block, that is the same as two said first blocks placed side to side and joined where they meet; and a third part, a block lock, that fits within the cored holes of top and bottom blocks, substantially snugly at the perimeter and overlapping the top surface of the bottom block so that when one block is placed on another with a block lock between the blocks are held in alignment to it and hence to each other.
Referring to FIG. 1 a block lock, 1, having a truncated pyramid shaped top, with a vertical portion, 1.1, at the bottom and a vertical square shape, 1.2, at the bottom. FIG. 2 shows a square block, 2, having a square tapered hole, 2.1, extruded through it from top to bottom and FIG. 3 shows in section how two said blocks are held in alignment with respect to one another by said block lock; the vertical portion 1.1 of item 1 fitting the bottom of hole 2.1, and the vertical square shape 1.2 fitting the top of hole 2.1.
For purposes of illustration no radii are shown but those familiar with blocks will know the cores generally have radii at the corners and are tapered; the blocks pictured do have a 3 degree taper but are without radii for purposes of illustration. The block lock 1 could be made to fit tightly at the bottom profile 1.1 or at the top profile vertical portion 1.2, or both, either all around the profile or by the addition of any protrusion on the surface; this has not been shown but will be obvious to those familiar with manufacturing techniques involved. The block lock shown is a plastic molded part.
Referring to FIG. 4 a block lock, item 3, having a flange 3.1 is shown and referring to FIG. 5, a square block, item 4, having a relief, 4.1, provided for flange 3.1 to fit in and FIG. 6 shows in section how a block lock, item 3, fits between the top of one square block and the bottom of another and that when assembled the two blocks are held in alignment with respect to the block lock and hence to each other.
Referring to FIG. 7, a block lock, item 5, having a flange, 5.1, that has a square perimeter equal to that of the top of square block item 2. FIG. 8 shows in section how 2 square blocks, item 2 stacked one on another with a block lock, item 5, in between are each held in alignment with respect to said block lock and hence to each other. It is conceivable that the block lock in this configuration could be a pre form partially cured that would cure and bond to the blocks with time or the addition of water but most likely it would just be plastic.
Referring to FIG. 9, a two-square block is shown, which is two square blocks joined side to side. FIG. 10 is an assembly of eleven item 1, block locks, five item 6, two-square blocks and one, item 2, square blocks and FIG. 11 is a section through the assembly in FIG. 10 showing how the blocks are held in alignment with respect to the block locks and hence to each other.
