## Title
Interlocking mesh

## Abstract

A wire mesh is formed by a plurality of identical wires. The wires interlock with each other by mutually receiving loops formed in the wires. Reinforcing wires welded to the loops reinforce the points of contact, and prevent the wires from rotating when locked together.

## Background
This application claims priority to our copending U.S. provisional patent application with the Ser. No. 60/881320, filed Jan. 19, 2007, and which is incorporated by reference herein.


FIELD OF THE INVENTION
The field of the invention is construction support devices.
BACKGROUND
It is known in the art to provide frames or skeletons to help reinforce and strengthen material that would otherwise be brittle. For example, rebar is commonly used in roads to provide added strength. For inexpensive jobs that require less strength, wire mesh is frequently sufficient.
Wire mesh, however, must be sized properly for different jobs and different needs. Additionally, large and planar wire mesh pieces can be rather cumbersome to transport. Smaller “sheets” of wire mesh may be transported on-site for ease of conveyance, but these sheets must be later welded on-site.
Thus, there is still a need for wire mesh that is easy to transport and can be assembled onsite without the use of additional tools.
SUMMARY OF THE INVENTION
The present invention provides apparatus, systems and methods in which a first wire with a first loop and a second wire with a second loop are hooked together so that the first and second loops receive each other. In a preferred embodiment, the first wire and the second wire are identical.
A reinforcing wire can be attached to the first wire or second wire to reinforce the loop. The reinforcing wire can be attached by any suitable means, but is preferably attached by welding. While the reinforcing wire can be attached to the first wire in any location, it is preferred that the reinforcing wire have a tight loop that attaches to the first loop. It is more preferred that the reinforcing wire comprise a plurality of tight loops that attach to a plurality of first loops on the first wire.
A grid can be formed by the mesh by using a plurality of first wires with a plurality of first loops and a plurality of second wires with a plurality of second loops, where the plurality of first loops mutually receive the plurality of second loops. The first wires are preferably parallel to one another and have identical shapes, and more preferably the first and second wires have identical shapes.
Various objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawings in which like numerals represent like components.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side perspective view of a wire
FIG. 2A is a front perspective view of a wire mesh using the wire of FIG. 1
FIG. 2B is an enlarged, fragmentary view of the wire mesh of FIG. 2A



DETAILED DESCRIPTION OF THE DRAWINGS
In FIG. 1, a wire 100 generally comprises a first wire 110 and a reinforcing wire 120.
First wire 110 has loop 130, which is shaped to receive a mating loop (not shown) on another wire. While loop 130 is shaped to mutually receive a loop identical to itself, various mating loops could be of any suitable shape to receive the other loop.
All suitable reinforcements are also contemplated. In FIG. 1, for example, loop 130 is welded to reinforcing wire 120 at weld point 150, and reinforcing wire 120 is shaped into a tight loop 140 at weld point 150, so as to provide additional reinforcement to loop 130. Reinforcing wire 120 also prevents first wire 110 from rotating about an axis when coupled with another wire.
In FIG. 2A, a wire mesh 200 comprises a plurality of identical wires, with an intersection point 210, shown more clearly in FIG. 2B.
Wire 220 has a loop 230 that intersects wire 100 at intersection point 210. Loop 230 mutually receives identical loop 130, locking both into place. Tight loop 140 prevents wire 220 from rotating after the wires have been locked into place. Multiple intersection points provide a durable wire mesh 200 without the use of additional tools to lock the wires in place about an X and Y axis.
The interlocking mesh can be used in any suitable construction application requiring a mixture of concrete or other mixing material with the intent of constructing a hard tri-dimensional surface, for example concrete slabs, prefabricated walls, bridge support beams, bridge slabs, roads, highway sound barrier walls, airport landing strips, maritime equipment, marine equipment, tunnels (submergible and over the ground), anti-aircraft protection shields, mining support, nuclear disposable (residue) cemeteries, caskets, and roof slabs.
Thus, specific embodiments and applications of a wire mesh have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
