Apparatus and method for interlocking blocks

Abstract

An improved block for making a horizontal, vertical, uneven and / or undulating surface has opposed upper and lower surfaces and opposed side surfaces. Sleeves extend through the block from opposed side surfaces and the sleeves on one pair of sides are at a different elevation from the sleeves at the other pair of sides. When blocks are placed to define a surface the sleeves align with sleeves in adjacent blocks and connecting ties are inserted through the sleeves to interconnect and stabilize the blocks. The blocks are preferably manufactured from concrete.

Description

FIELD OF THE INVENTION[0001]This invention relates to blocks used to create horizontal and vertical surfaces and the like, and more particularly to blocks such as concrete paving blocks that incorporate a system for interlocking adjacent blocks to stabilize the blocks relative to one another.BACKGROUND OF THE INVENTION[0002]There are many different types of blocks used as a primary surface in horizontal or vertical applications, including for example paving bricks to cover driveways, patios, walks, walls and the like. Other examples include blocks that are used to form walls such as retaining walls and decorative walls on patios and the like. Typically, such blocks are manufactured from concrete or similar materials formed into desirable shapes. The blocks are placed in any desirable manner to form a surface that is both resilient and attractive.[0003]The stability of a surface or a wall manufactured with blocks may be increased by tying the blocks together in some manner. There are...

Problems solved by technology

However, most such systems result in blocks that are difficult to manufacture on a large-scale basis, and often the blocks have protrusions such as keys that are prone to breaking during transport and handling, and periphery form systems do not perform stabilization very well.

However, even when a grade is prepared in the best manner possible the surface of the driveway may degrade over time with the weight of cars driven over it.
