Abstract
A portable ramp for providing a bridge between surfaces of different elevations. The ramp includes a unitary construction which includes a traction plate, foot section and tongue section. The foot section has one or more serrations along a curved surface. The tongue section includes a binder for increased friction at the elevated surface. A safety line and hand hold are also disclosed.

A utility ramp for providing a bridge between a ground level surface and a raised surface, said ramp being adapted to facilitate the movement of items from one of said surfaces to the other of said surfaces, said ramp comprising a unitary traction plate;
- said traction plate including a first end and a second end, said first end including an integrally formed tongue section and said second end including an integrally formed foot section;
- said tongue section being adapted for securement to said raised surface and said foot section being adapted to engagingly support said traction plate on said ground level;
- said traction plate is formed from a sheet metal stamping and includes oppositely disposed, downwardly formed, substantially coextensive, panel portions, each panel portion further defining a substantially coextensive, generally U-shaped channel, said channel forming a cross section having a base portion and a pair of bifurcated leg portions extending therefrom;
- and wherein each of said bifurcated leg portions of said channel includes an arcuate portion defining a plurality of exposed serrations engageable with said ground surface.
A utility ramp for providing a bridge between a ground level surface and a raised surface, said ramp being adapted to facilitate the movement of items from one of said surfaces to the other of said surfaces, said ramp comprising a unitary traction plate;
- said traction plate including a first end and a second end, said first end including an integrally formed tongue section and said second end including an integrally formed foot section;
- said tongue section being adapted for securement to said raised surface and said foot section being adapted to engagingly support said traction plate on said ground level;
- said tongue section of said first end including a U-shaped protective binder attached to the marginal edge of said tongue section;
- and wherein said U-shaped binder includes a bail portion having a pair of bifurcated legs extending therefrom, said legs each terminating in an upstruck barbed portion, said upstruck barbed portion extending longitudinally and coextensive with said binder.
A utility ramp for providing a bridge between a first surface and a second surface, said ramp comprising:
- a unitary traction plate;
- said traction plate including a first end and a second end;
- said first end having a receptacle integrally formed therein, said receptacle being adapted to receive a predetermined portion of said first surface;
- said second end having a foot member integrally formed therein, said foot member being adapted to engagingly support said traction plate on said second surface;
- said traction plate being formed from a sheet metal stamping and including oppositely disposed, downwardly formed, substantially coextensive panel portions, each panel portion further defining a substantially coextensive, generally U-shaped channel said channel forming a cross section having a base portion and a pair of bifurcated leg portions extending therefrom;
- and
- wherein each of said bifurcated leg portions of said channel includes an arcuate portion defining a plurality of exposed serrations engageable with said second surface.
A utility ramp for providing a bridge between a first surface and a second surface, said ramp comprising:
- a unitary traction plate;
- said traction plate including a first end and a second end;
- said first end having a receptacle integrally formed therein, said receptacle being adapted to receive a predetermined portion of said first surface;
- said second end having a foot member integrally formed therein, said foot member being adapted to engagingly support said traction plate on said second surface;
- said receptacle of said first end including a U-shaped protective binder attached to a marginal edge of a tongue-shaped projection;
- and
- wherein said U-shaped binder includes a bail portion having a pair of bifurcated legs extending therefrom, said legs each terminating in an upstruck barbed portion, said upstruck barbed portion extending longitudinally and coextensive with said binder.
