Portable accessible ramp system

A portable accessible ramp system comprising:

• at least first and second plastic one-piece rectangular platforms, each platform comprising (A) left, right, front, and back edges, and a floor having a substantially flat upper surface, (B) a center hub located in a center of the platform on the bottom side of the floor, the center hub having a first thickness and including a downwardly-facing center receptacle configured to receive a center leg assembly, (C) a plurality of radial stringers spaced and distributed around the center hub and extending radially outwardly therefrom, each radial stringer gradually tapering in thickness from the first thickness at an intersection with the center hub to a second thickness at an end proximate the respective left, right, front or back edge wherein the second thickness is much less than the first thickness, and (D) left, right, front and back sidewalls extending downwardly from the floor at the respective left, right, front and back edges with a plurality of sidewall through-holes being distributed along a length and extending through each sidewall of the left, right, front, and back sidewalls wherein the front edge of the first platform abutting the back edge of the second platform;
• at least left and right L-brackets, each L-bracket of the left and right L-brackets including a first L-leg and a second L-leg orthogonal to the first L-leg, the second L-leg including a plurality of L-bracket through holes corresponding and aligning with at least some of the plurality of sidewall through holes;
• a plurality of left and right side leg assemblies, each side leg assembly of the plurality of left and right side leg assemblies including (i) a side length-adjustable leg, (ii) a side footer received on a bottom end of the side length-adjustable leg, (iii) an angularly-adjustable mounting bracket received proximate a top end of the side length-adjustable leg;
• and
• first and second center leg assemblies, each center leg assembly of the first and second of center leg assemblies including (1) a center length-adjustable leg with top and bottom ends, and (2) a center footer received on the bottom end of the center length-adjustable leg;
• wherein (a) the first and second center leg assemblies are received in the respective center receptacles of the first and second platforms, (b) the respective left sidewalls of the first and second platforms rest on the first L-leg of the left L-bracket, (c) the respective right sidewalls of the first and second platforms rest on the first L-leg of a first right L-bracket, (d) first, second and third left side leg assemblies of the plurality of left and right side leg assemblies are secured to the second L-leg of the first left L-bracket by way of the respective angularly-adjustable mounting brackets with the first and third left side leg assemblies being secured proximate the ends of the first left L-bracket and the second left side leg assembly being secured to the first left L-bracket proximate a center thereof adjacent to a location wherein the front edge of the first platform abuts the back edge of the second platform, and (e) first, second and third right side leg assemblies of the plurality of left and right side leg assemblies are secured to the second L-leg of the first right L-bracket by way of the respective angularly-adjustable mounting brackets with the first and third right side leg assemblies being secured proximate the ends of the first right L-bracket and the second right side leg assembly being secured to the first right L-bracket proximate a center thereof adjacent to a location wherein the front edge of the first platform abuts the back edge of the second platform.
