    Abstract: An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. One end of the torsion spring is fixed to a spring tension trolley. The trolley translates within a trolley guide mounted to the building structure. The other end of the torsion spring is fixed to a shaft running through the torsion spring. This allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the “snake-like” or serpentine appearance from an improper fixed torsion spring length.

    Abstract: A closure is described. In a preferred embodiment a novel door roller is presented that is more resistant to a dislodgement force. The door roller comprises a bearing that rolls on a piece of round stock that is part of a door guide. When a dislodgement force is imposed on the door, the door bows and the bearing contacts the stock preventing dislodgement of the door roller from its track and allow the door to remain operational.

    Abstract: An overhead door system featuring independent, unconnected panels is described. Each panel end is operatively carried within a pair of parallel tracks. The weight of the door decreases as the door is lifted and each panel completely disengages from its adjacent panel as it reaches the stacked position. This allows for a linear spring torque to door weight relationship requiring a very small motor compared to existing designs to provide the lifting torque necessary to operate the door.

    Abstract: The disclosed invention prevents damage to a hood and its contents. In a preferred embodiment, a first and second support member are mounted on either side of an access opening. A cross member is slidably retained in a protective, starting position within the support members. The cross member is preferably positioned above the access opening in front of a coiling door hood such that a striking force directed at the hood first encounters the cross member. When struck, the cross member slidably retracts against a force assembly to dissipate the striking force and upon withdrawal of the striking force the cross member returns without human intervention to the protective, starting position.

    Abstract: A closure locking design is presented that is more resistant to a displacement/dislodgement force. A closure end strip is fixed to a closure end and received by a closure guide first section. A rotatable tube and hook assembly run vertically within a closure guide second section. When rotated to a locking position a hook member of the tube and hook assembly rotates through a slot cut in the guide and through a cutout in the closure end strip to restrictively engage the closure.

    Abstract: A multi-panel overhead stacking door which allows for the addition of multiple panels across an opening width. A vertical extrusion acts a guide for the panel above and/or below it. The vertical extrusion serves as a moving guide which thereby allows for the relatively easy addition of multiple panels. At each end of the door is a series of formed parts that are attached to the ends of the end panels and movably maintained with door guides. The assembled door is driven by, for example, a driven shaft, positioned at the top of or above the door opening. The shaft comprises drums to windingly and unwindingly receive a lifting member. The lifting member runs from the drum to the bottom panel assembly behind each vertical extrusion.

    Abstract: A vertically coiling door assembly that is used for emergency egress. Upon notice of a predefined alarm state, after a delay the door deploys by gravity, stopping upon contact with an obstruction. The door may be lifted at any time without power and after a set amount of lift powered movement is triggered moving the door to a preset height, pausing the door at that height, and then resuming gravity deployment. In the total absence of power the door may still be lifted, with resumption of gravity deployment upon removal of the lifting force.
