Abstract: Portable wheel chair ramps consist of a platform and ramp sections. The platform and ramp sections are sandblasted. Ramp sections have an extended adjustable legs, (U.S. Pat. No. 6,810,995.). Ramp sections have an extruded locking mechanism underneath that connect one section to others using a specifically designed tube and a configurated J hook. Rails are then connected to extended adjustable legs of ramp sections and secured to each other with an end post and an angle piece of aluminum, then bolted together, insuring the rigidity of the railing system to comply with codes. Bolting the rails together with an inner handrail gives a continuous railing system for the purpose of individuals using a wheel chair to traverse the ramp. Inner rails are secured to the railing system and the leg posts with a bolt, this rail runs the entire length of the ramp on both sides.

Abstract: An adjustable stair and platform system. The apparatus includes a set of stairs which is affixable to a platform at a first height or alternately at a second height. Both the platform unit and the stair unit include vertically adjustable legs above ground engaging feet. The stairs includes a stair rail frame which is releasably affixable to a side hand rail frame provided for the platform unit. The hand rail frame provided for the platform unit includes an end rail which is pivotally mounted to the side hand rail frame. The end rail frame is changeable to support a right hand or a left hand configuration of the side hand rail frame provided on the platform unit. The combination of vertical adjustability, and left and right hand adjustability, make the unit adaptable for various installation configurations, and avoids the need for multiple stair system units for portable buildings.
