Abstract
A door system designed for buildings that store large objects such as airplanes or farm, marine, and other heavy equipment. The door system is comprised of a door, a lift frame, and a brake system disposed within the lift frame and coupled with the door. Furthermore, an articulating arm system connects to the lift frame and the door and a drive system connects to the brake system. The drive system moves the brake system within the lift frame such that the brake system and the articulating arm system guide the door between an open and a closed position.
Claims14
A door system, comprising:
- a one-piece tilt-up door;
- a lift frame, wherein the lift frame comprises first and second guide columns with a header therebetween;
- a brake system disposed within the lift frame and coupled with the door, wherein the brake system comprises a first brake assembly disposed in the first guide column and connected to the door via a lift pin, wherein the first brake assembly is movable between an unlocked position whereby the first brake assembly moves relative to the first guide column and a locked position whereby the first brake assembly engages the first guide column to stop movement of the first brake assembly relative to the first guide column;
- an articulating arm system connected to the lift frame and the door;
- and
- a drive system connected to the brake system, wherein the drive system moves the brake system within the lift frame such that the brake system and the articulating arm system guide the door between a closed position and an open position, further wherein:
- moving the door from the closed position to the open position, comprises:
- the drive system raising the brake system within the lift frame such that the brake system moves the door vertically upward,
- the door rotating relative to the brake system, and
- the articulating arm system guiding the rotation of the door such that the door rotates away from the lift frame thereby tilting the door away from the lift frame until the drive system ceases raising the brake system within the lift frame, whereby the door resides in the open position, and
- moving the door from the open position to the closed position, comprises:
- the drive system lowering the brake system within the lift frame such that the brake system moves the door vertically downward,
- the door rotating relative to the brake system,
- the articulating arm system guiding the rotation of the door such that the door rotates toward the lift frame thereby tilting the door to a substantially parallel position with the lift frame, and
- the drive system ceasing lowering the brake system within the lift frame, whereby the door resides in the closed position.
