Abstract
A lift-assisted entrance to provide ground-level access to an external basement entryway to a building. The lift-assisted entrance has a pivotable roof vertical, rectangular side walls, and a front face with vertically oriented, outward opening double doors, all fabricated from lightweight visco-elastic material. The roof section opens upward and tilts away from the plane of the front face and is supported by two actuators. Doors located on the front face open outward to provide full access to the basement entryway. The roof is shaped to reflect the architectural features or the style of the building to which the lift-assisted entrance is attached and may be a gabled roof The side walls and front face may also include architectural features--such as windows--that emulate those features found on the building. The visco-elastic material can be molded with a relief pattern that emulates the appearance of house shingles or clapboard siding, or roof shingles.
