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. | 12-31-2015 |
| 20160376830 | HYDRAULICALLY OPERATED OVERHEAD TILT-UP DOOR WITH STABILIZER - 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. | 12-29-2016 |

| 20130019533 | OVERHEAD DOOR ASSEMBLY WITH COUNTER BALANCE SYSTEM - A counter balance system for an overhead door assembly is provided. The overhead door assembly includes a door frame, an overhead door, and a door lifting assembly. The door lifting assembly includes an extension spring, a cable, and a pulley assembly. The pulley assembly guides the cable as the door is moved between a raised open position and a lowered closed position. A pulley of the pulley assembly is mounted so that an axis of rotation of the pulley remains perpendicular to a portion of the first cable extending between the pulley and a lower portion of the overhead door as the door is moved between the raised open position and the lowered closed position. | 01-24-2013 |
| 20150354257 | OVERHEAD DOOR BACKUP SPRING SYSTEM - The present invention essentially comprises a spring engagement system of an overhead door backup spring system operable upon failure of a main spring, and method of using the spring engagement system. The spring engagement system has a spring engagement unit operably associated with a spring, and an engagement unit operably associated with the spring engagement unit. The engagement unit is engageable with the spring engagement unit in an engaged position upon activation thereof. The engagement unit can transfer torque from the spring to a shaft in the engaged position. The engagement unit is actuating by engagement of an activation unit, which is actuated upon failure of the main spring associated with an overhead door. | 12-10-2015 |
| 20150368950 | METHOD AND APPARATUS FOR A DOOR - 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. | 12-24-2015 |

| 20120279129 | OVERHEAD GATE SYSTEMS - Overhead gate systems include a gate assembly having a barrier and that defines a passage. When in a deployed configuration, the barrier is adjacent to the ground and restricts ingress to and egress from the installation site, and the passage is distal the ground surface relative to the barrier, permitting access to and from the installation site via the passage. When in a stowed configuration, the barrier is not adjacent to the ground surface and does not restrict ingress to and egress from the installation site. | 11-08-2012 |
