Patent ID: 7467436

Claim:
An adjustable ramp, comprising: (a) an inclined plane that includes a lower end and an opposite upper end, a first side, and an opposite second side; (b) a base member, wherein said base member includes a pivot axis and wherein said pivot axis extends longitudinally through a first end of said base member and also through said lower end of said inclined plane, and (c) wherein said inclined plane is pivotally attached to said base member at said pivot axis and wherein said incline plane is adapted to pivot over a predetermined range from a first lower position into a second upper position; (d) means for maintaining said inclined plane at a location within said predetermined range that said inclined plane is disposed at; and (e) wherein said base member includes a first base member and a second base member, and wherein said first side of said inclined plane includes a planar member that is perpendicular with respect to a plane of said inclined plane, and wherein said member is attached to said inclined plane at said first side thereof, and wherein said second side of said inclined plane includes a second planar member that is perpendicular with respect to said plane of said inclined plane, and wherein said second member is attached to said inclined plane at said second side thereof, and wherein said means for maintaining said inclined plane in a location includes a first fastener that passes through a first opening in said first side and through a second opening in said first base member, and including a second fastener that passes through a third opening in said second side and through a fourth opening in said second base member, and wherein when said first fastener and said second fastener are tightened, a friction intermediate said first base member and said first side and intermediate said second base member and said second side is sufficient to retain said inclined plane in said location.
