Abstract
A horizontal door assembly is provided using a gas spring as a lifting mechanism for the door leaf. A special bracket having a number of pivot pin openings is employed to rotatably couple the gas spring to the door frame, whereby different lifting forces can be applied to the door by the user of the door by adjusting the position of the gas spring in the bracket. A brace is also provided to support the bracket and gas spring to enhance operation of the door. A resilient material such as EPDM is used to decelerate movement of the door leaf to the open position and provide a stable door leaf when in the open position. Sections of the door assembly are provided with screw studs to facilitate on-site construction and packaging and shipping of the door assembly.
