The client required an internal ramp such that she could be wheeled by a carer from floor level up to the patio door threshold onto the commercial off-the-shelf (COTS) aluminium suitcase ramp for access outside.
A lightweight 12mm plywood ramp was made with 3x supporting rails underneath, profiled to rest on the door step, with 4x thin non-slip rubber feet protecting the wooden floor.
The ramp is long enough to give a 1:10 gradient and wide enough to sit either side of the suitcase ramp. There are 2x side rails to keep the wheel chair on the ramp and these are extended to the patio door groove with location pegs to prevent movement once fitted. There are 2x finger holes, so it can be lowered down without finger entrapment.
