TECHNICAL FIELD
The present disclosure relates to pavers, and more specifically to a load bearing paver and method of installation that improves drainage while maintaining load-bearing capacity.
BACKGROUND OF THE INVENTION
Pavers are used to provide a stable surface without the need for pouring concrete, asphalt or other materials. While pavers are easier to install than such other materials, they suffer from a number of drawbacks, such as instability under load.
SUMMARY OF THE INVENTION
In accordance with an exemplary embodiment of the present disclosure, a paver is provided that includes a first side having a length L1 and a groove disposed along the length L1 of the first side, such as a groove that is located midway between the top surface and the bottom surface of the paver. The paver has a second side having a length L2 and a tongue disposed along the length L2 of the second side, so that the tongue of the second side of the paver can be placed into the groove of another paver. The paver has a third side opposite the first side and having a tongue with length L3 disposed along the first side, where the length L3 is less than the length L1, thus forming a flat surface area on the third side where the tongue does not extend to, and also allowing the tongue of the third side of the paver to be placed into the groove of another paver and adjacent to a tongue from the second side of a third paver. A fourth side has a substantially flat surface with a length L4, where the length L4 is equal to L1 minus L3, or the flat surface area of the third side, so that the fourth side of the paver can be placed adjacent to the third side of another paver. In this manner, the pavers can be interlocked to provide additional stability.
Other systems, methods, features, and advantages of the present disclosure will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present disclosure, and be protected by the accompanying claims.

Paver 100 includes tongue 104, which has a length L3, and tongue 110, which has a length L1. Tongue 104 is disposed on side 102, which has a length L2 which is equal to two times L3. Tongue 110 is disposed on side 108, which has a length L1. Side 106 can be placed upwards or downwards in use, to form the paver surface or paver base, respectively. Paver 100 can be formed in a mold by a wet cast process, a dry cast process, or in other suitable manners, and is configured so that the mold can be lifted off of paver 100 after it has stabilized. In one exemplary embodiment, side 108 can be the cull of paver 100, side 106 can be one of the beds of paver 100 and side 102 can be the side of paver 100.
FIG. 2 is a diagram of paver 100 showing groove 202 disposed in side 204. Groove 202 has a length L2, such that tongues 104 and 110 can be inserted into groove 202 when paver 100 is installed. Side 206 is opposite to side 106, and can be placed upwards or downwards in use, to form the paver surface or paver base, respectively.
FIG. 3 is a bottom view of paver 100 showing tongue 104 disposed on side 102, groove 202 disposed in side 204, sides 106 and 206, and bottom surface 208. Bottom surface 208 is flat, and forms the base of paver 100 during dry casting, or the top surface during wet casting. In one exemplary embodiment, side 208 can be the end of paver 100, sides 106 and 206 can be the beds of paver 100, side 102 can be the side of paver 100 and side 204 can be the face of paver 100.
