An overhead door system including a frame, a door leaf and a first hydraulic cylinder. The door leaf is pivotally mounted to the frame. The first hydraulic cylinder has a first cylinder end and a second cylinder end. The first cylinder end is operably attached to the frame. The second cylinder end is operably attached to the door leaf. The first hydraulic cylinder is capable of moving the door leaf between a closed configuration and an open configuration. At least one of the frame and the upper door panel has a slot formed therein. When the door leaf is in the closed configuration, the first hydraulic cylinder is substantially recessed in the slot.

An emergency bi-fold door closing prevention system includes a building having an access opening with an upper edge. A bi-fold door is hingedly mounted to the building wall and includes a plurality of panels each being laterally elongated. The plurality of panels includes a bottom panel having a bottom edge that is positionable adjacent to a floor surface to define a closed position. A safety line assembly is attached to and extends between the building wall adjacent to the upper edge and the bi-fold door adjacent to the bottom edge. The safety line has an extendable length. The length of the safety line assembly extends when the bi-fold door moves toward the closed position below a threshold velocity. The length of the safety line assembly is inhibited from extending when the bi-fold door moves toward the closed position above the threshold velocity to prevent unimpeded falling of the bi-fold door.

A frame for an overhead door has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount the overhead door to the header to allow hydraulic cylinders to selectively move the overhead door between an open position and a closed position.

A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door.

A bi-fold overhead door system that includes a frame, a bi-fold overhead door and a hydraulic cylinder. The bi-fold overhead door has an upper door leaf and a lower door leaf. The upper door leaf is pivotally mounted to the frame. The lower door leaf is pivotally mounted to the upper door leaf. The hydraulic cylinder has a first cylinder end and a second cylinder end. The first cylinder end is operably attached to the frame. The second cylinder end is operably attached to the upper door leaf. The hydraulic cylinder is capable of moving the bi-fold overhead door between a closed configuration and an open configuration. At least one of the frame and the upper door leaf has a slot formed therein. When the bi-fold overhead door is in the closed configuration, the hydraulic cylinder is substantially recessed in the slot.

A LED controller device that regulates one or more light systems affixed to a vehicle access gate. The controller receives inputs from one or more sources and actuates one or more light systems in response to particular signals, or triggers. The controller also monitors and records usage of the light system and may also record usage of other devices acting in concert with the light systems and/or an access gate. A software configuration tool is used to prepare a gate operation profile that identifies triggering events and the actions the controller takes upon the occurrence of the triggering events. That gate operation profile is flashed onto the controller's CPU. The controller may be contacted and controlled remotely or locally.

An overhead door and frame has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies connect the upright columns to the header. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to selectively move the overhead door to an open position and a closed position.

A tilt-up door for a building having a relatively wide door opening having a door panel including top and bottom horizontal members and vertical side members connected to the top and bottom horizontal members. The vertical side members each include a pivot point, affixed to pivot translation points which move upward or downward when an actuator is activated, such that first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each affixed at its lower aspect to each side member at a position at or slightly above the center point of the door frame, and each cam extending upwardly and arcuately toward the interior of the building, to a point in space where said cam contacts a cam follower extended inwardly at approximately a right angle with respect to both the adjacent top horizontal members of the door frame, and to the Support Structure or stile to which it is fixed at its proximate end, thereby guiding the door as it is moved between its substantially open substantially horizontal position, and to be lowered into its substantially vertical substantially closed position. Each pivot translation point is lifted or lowered by means of an actuator, such as a screw, chain or hydraulic system, depending upon the needs of the user or environment, which causes the door to open or close. The door panel contains an integral track or cam which is substantially elliptical having a radius such that each integral track rides on a stationary roller which allows the panel to tilt into position. The actuation system is mounted on or in columns on either side of the door to allow the door to move into the various open and closed positions.

An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar and a support assembly and the upright columns and the upright I-bar are secured to a base adapted to be secured to a floor of a building. One of the splice assemblies is fastened to each upright column. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders connected to the support assemblies to move the overhead door to an open position and a closed position.

A frame for supporting a door has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. The splice assemblies are fastened to the upright columns.
