Abstract: The door system of the present invention includes a mounting frame assembly and a tilt-up door pivotally and slidably mounted within the mounting frame assembly. The door system is installed in a door rough opening as an integral unit, simplifying installation. At least one hydraulic cylinder is utilized to actuate the door between its open and closed positions. A stabilizer including a door component secured to the tilt-up door and a door component secured to the frame assembly are used to stabilize the door when it is in its open position.

Abstract: There present invention relates to a single panel, hydraulically driven door system. The door and hydraulic cylinder are mounted to the door frame so the door and door frame can be easily installed to a building rough opening. From the door closed position, the hydraulic cylinder raises the door slightly to release a locking mechanism, before the door is rotated to its open position. A control arm and guide track guide movement of the door between its open and closed positions. A variable frequency drive controls the speed of the hydraulic cylinder extension and retraction to provide a smooth transition of the door when moving between its open and closed positions.

Abstract: The present invention is a door assembly including a rectangular door frame, a bi-fold door pivotally mounted at the top of the rectangular door frame and at least one hydraulic cylinder assembly. The hydraulic cylinder assembly is pivotally secured by a first end to a cylinder support mounted on a back side of the door frame, and by a second lower end to a cylinder support secured to a back surface of a top panel of the bi-fold door. In the door closed position, the longitudinal axis of the cylinder is oriented at an acute angle away from a plane defined by the door pivot axis and the lower pivot axis of the cylinder. A hydraulic control assembly controls movement of the door between an open and closed position.
