Abstract
A lightweight folding portable ramp for use with an electric scooter or a wheelchair which may be positioned by the user without dismounting from the means of conveyance. The ramp is comprised of two ramp members and may include a rectangular connecting means, all of which are hinged together. Handles for lifting are provided on the ramp members.
Claims18
A lightweight portable ramp for use in allowing a wheeled vehicle to traverse between a first upper level and a second lower level, said ramp comprising:
- two rigid planar ramp members having a hinging means therebetween;
- wherein each rigid planar ramp member has a bent first end adapted for operative engagement with said first upper level and a second end adapted for operative engagement with said second lower level;
- said ramp members being adapted to supportingly span between said first upper level and said second lower level and being of a small size and low weight so as to be maneuverable in to and out of place by a person using one hand;
- and
- wherein said hinging means connects said two rigid planar ramp members in side-by-side adjacent relation to each other between said bent first end and said second end, so that said portable ramp may be changed between a transportable position whereat said two ramp members are folded against one another and an in-use position whereat said ramp members are pivoted outwardly so as to be generally co-planar.

- wherein said connecting means has two opposite sides, each of said opposite sides adapted for hinged attachment to one of said two rigid planar ramp members, said connecting means acting as a third member;
- and
- wherein said hinging means connected said two rigid planar ramp members in side-by-side adjacent relation to said connecting means, one at each of said two opposite sides, between said bent first end and said second end, so that said portable ramp may be changed between a transportable position whereat said two ramp members and said connecting means are folded against one another and an in-use position whereat said ramp members and said connecting means are pivoted outwardly so as to be generally co-planar.
