In-floor vehicle ramp

摘要

A ramp system includes a base frame adapted to be mounted to a vehicle. First and second elongate track members are mounted to the base frame in generally parallel, spaced-apart relation so that they extend along a longitudinal direction. A trolley assembly is moveably mounted to the first and second elongate track members so that the trolley assembly is moveable along the longitudinal direction between retracted and extended positions. A ramp member is pivotally mounted to the trolley assembly. A support roller mounted to the base frame supports a portion of the ramp member. A handle assembly mounted to the ramp member allows a user to move the ramp member between the retracted and extended positions.

1. A ramp system for a vehicle, comprising;
a base frame adapted to be mounted to the vehicle; a first elongate track member having a C-shaped cross-section mounted to said base frame; a second elongate track member having a C-shaped cross-section mounted to said base frame in generally parallel, spaced-apart relation to said first elongate track member, said first and second elongate track members extending generally along a longitudinal direction; a trolley assembly sized to extend between said first and second elongate track members; a first guide wheel mounted to a first end of said trolley assembly, said first guide wheel being sized to be received within the C-shaped cross-section of said first elongate track member; a second guide wheel mounted to a second end of said trolley assembly, said second guide wheel being sized to be received within the C-shaped cross-section of said second elongate track member; a generally rectangularly-shaped ramp member having a leading edge and a trailing edge, the trailing edge of said ramp member being pivotally mounted to said trolley assembly; a first elongate side rail mounted to said ramp member; a second elongate side rail mounted to said ramp member in generally parallel, spaced-apart relation to said first elongate side rail; a support roller mounted to said base frame at a position between said trolley assembly and the leading edge of said ramp member, said support roller contacting an underside of said ramp member; a handle assembly mounted to said ramp member, said handle assembly comprising a generally elongate rod having a handle end and a lower end, and a spring mounted to the lower end of said rod, said spring mounting said elongate rod to said ramp member in an orientation generally perpendicular to said ramp member, said spring allowing said elongate rod to be articulated with respect to said ramp member; a floor plate assembly mounted to the floor of the vehicle; and a transition plate pivotally mounted to said floor plate assembly, said transition plate being configured to close a gap between said floor plate assembly and said ramp member when said ramp member is in an extended position.
