Tongue and Groove Interlocking Pavers

Abstract

Multilayered pavers comprise adjoining outer sections of male components that are adjacent to each other with opposite and adjacent outer sections that define female voids that comport to male sections of the pavers. The multiple layer or three layer approach allows for multiple points of contact and retention of the pavers. Slanted top and bottom sections of protrusions allow for ease of insertion of one paver into the other. A cambered perimeter edge of a top layer of the paver allows for ease of attachment to machinery sometimes used to transport each paver to a desired spot and for insertion into an adjacent paver.

Claims

1. A multilayered paver comprising: a) a first layer comprising a top surface having cambered edges; b) two adjacent sides having male protrusions and two opposite and adjacent sides defining female voids; c) the two sides having male protrusions comprising: i) the first layer protruding past a second layer ii) a third layer protruding past the second layer d) the two sides having female voids, the first void defined by the top surface protruding past the second layer and the second void defined by the second layer protruding past a lower third layer.

2. The multilayered paver of claim 1 wherein the top and bottom surface of the third layer are slanted.

3. The multilayered paver of claim 2 wherein the surfaces defining the second void and slanted to comport with the top and bottom surface of the third layer.

4. The multilayered paver of claim 3 in the shape of a square.

5. The multilayered paver of claim 3 in the shape of a rectangle.

[0052] FIG. 1 shows multiple layers of a disclosed paver.

[0053] FIG. 2 shows two pavers disposed with each other, with the paver on the right having a male protrusion 133 disposed within a female void 132, the void defined by a protrusion section or surface 113 of the first layer.

[0054] FIG. 3 is a rectangle form or long form with rebar disposed within. The boards or strips of wood at the perimeter help show the layers of male protrusions and female voids.

[0055] FIG. 4 is a square form or short form with rebar disposed within. The boards or strips of wood at the perimeter help show the layers of male protrusions and female voids.

[0056] FIG. 5 depicts a series of pavers having male protrusions in foreground and left side and female voids on the right side back side. The combination of square and rectangle pavers avoids long seams and help to stabilize a paver system.

[0057] FIG. 6 depicts a tractor moving a hydraulic system attached to a paver claw piece that may use C clamps or other means to attach to a paver. The multi layered nature of the disclosed pavers provides extra areas of attachment.

[0058] Referring to FIG. 7, a short square paver is shown on the right side foreground and an intersecting long or rectangular paver is shown on the left side back ground. As to the short square paver a male protrusion 130 is exposed on the right, in the foreground the adjacent protrusion is intersecting or disposed into a void of the boarder piece. Referring to the long or rectangle paver, a male protrusion in disposed within a void of the square paver. This figure helps to show the symmetry male protrusions being adjacent and female voids being opposite the male voids but adjacent to each other.

[0059] FIG. 8A and FIG. 8B show greater detail of the multilayered features of the disclosed pavers.

[0060] The multilayered nature of the disclosed embodiments has an advantage over the prior art in that if a middle paver breaks or becomes out of level due to differential earth movement, the middle paver may be cut away with a concrete saw and then pulled away from the other pavers by virtue of the sloped female voids. Thus the sloped female voids and/or sloped protrusions that define female voids allow for a measure of differential earth movement, ease in installation and ease in removal as the pavers have tolerances in their frictional attachment.

[0061] The term multilayered may mean that the disclosed pavers comprise various features and geometry and described herein and/or as shown in the drawings. The use of multiple layers or multiple levels of protrusions and voids allows for multiple layers of frictional attachment to hold the pavers in place and sloped voids as discussed above to assist in both installation and deconstruction.
