High speed door assembly
View Patent ↗The present invention is directed to an industrial high-speed door assembly having a reduced door panel width and having guides for guiding the door which extend into a passageway but are resilient, tough, or resiliently collapsible, to either withstand impacts from vehicle collisions or moveable during opening of the door to avoid collisions while returning for guidance upon closing the door.
1. A high-speed door assembly operatively mounted proximate an opening having a width defined by opposed sides, the high-speed door assembly being capable of vertically moving a door panel to permit and prohibit access through the opening, the high-speed door assembly comprising:
a first guide operatively mounted proximate the opening and having opposed surfaces between which a portion of the door panel is guided during opening and closing and wherein at least a portion of the opposed surfaces extends into the opening;
a second guide operatively mounted proximate the opening and having opposed surfaces between which a portion of the door panel is guided during opening and closing and wherein at least a portion of the opposed surfaces extends into the opening; and,
a guide moving assembly operatively connected to at least one of the first or second guides, where, in conjunction with opening and closing of the door panel, at least a portion of at least one of the first or second guides move between a first position and a second position, the guide moving assembly having
a counter-weight operatively attached to the door panel;
a chute mounted proximate the opening and operatively attached to at least one of the first or second guides, the chute including a path to guide the counter-weight; and,
a deflection member attached to at least one of the first or second guides and positioned within the path to guide the counter-weight, wherein upon initial contact of the counter-weight with the deflection member, the guide will move.
2. The high-speed door assembly of claim 1 wherein the at least first or second guides extends operatively into the opening in the first position to guide the door panel, and a portion of the at least first or second guide does not significantly extend into the opening in the second position.
3. The high-speed door assembly of claim 1 wherein the guide moving assembly includes an actuator.
4. The high-speed door assembly of claim 1 wherein the guide moving assembly includes a gravity-based bias mechanism.
5. The high-speed door assembly of claim 1 wherein the first guide being pivotably mounted proximate the opening.
