Adjustable doorway ramp apparatus
First Claim
1. An adjustable wedge-shaped ramp apparatus positionable on a first level relative to a vertically spaced upper level comprising,a first wedge-shaped member including a lower planar face, a rear planar face orthogonally formed to said lower face, and an upper surface joining said rear and lower planar faces, andsaid first member pivotally joined at an edge, formed by the junction of the upper surface and the lower planar face, to an underlying second member wherein the pivotal joining includes a plurality of hinges secured to said upper surface of said first member and to an upper surface of said second member, anda third member underlying said second member and mechanically and removably secured to said second member, and said second and third members formed of trapezoidal cross-sectional configurations.

Abstract
An adjustable doorway ramp apparatus is set forth wherein a doorway ramp is of a triangular wedge member configuration and includes a first, second, third, fourth, fifth, sixth, and seventh ramp associated therewith. The first ramp is positioned at an uppermost portion of the ramp apparatus and is pivotally mounted in forwardmost portion thereof with a fourth ramp pivotally mounted displaceably rearwardly therefrom by a rack and pinion arrangement. A second ramp is in underlying position to said first ramp and is of a trapezoidal configuration and releasably securable to a third ramp of trapezoidal configuration dimension substantially greater than that of said second ramp. A fifth ramp is positionable between said first and second ramps to arcuately position said first ramp relative to said second ramp with a sixth ramp and seventh ramp slidably mounted within said third ramp for positioning about an associated door sill.
