Abstract

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.

Dependent claims

A tilt-up door for a building having a door opening to be closed by a door, the door having a vertical closed position and being movable in an opening cycle to a generally horizontal open position and being movable in a closing cycle from the open position to the closed position, the door having dimensions that are substantially equal to, slightly smaller than, or slightly larger than the door opening to permit the door to be installed within said opening, or to close over said opening, said door comprising:

a. a door frame including at least top and bottom horizontal members, and at least two vertical side members connected to the top and bottom horizontal members at opposite ends of the top and bottom horizontal members and a barrier affixed thereto,
b. a pivot point affixed to each of the at least two vertical side members and positioned between the top and bottom horizontal members of said door frame, said pivot point engaged with an actuation mechanism which when powered raises or lowers each said pivot point,
c. first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each said cam affixed at its lower aspect to each side member at a position at or slightly above the center point of the door panel, 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 member, and to the vertical member, to which said cam is fixed at its proximate end, thereby causing the door to open into its horizontal position by following each said cam, and to be lowered into its vertical closed position, also by following each said cam;
and
d. at least one actuation mechanism which, when powered, causes each said pivot point to be vertically raised or lowered, thereby causing the door to open into its horizontal position by each cam follower following each said cam, and to be lowered into its vertical closed position, also by each cam follower following each said cam.

A system comprising a tilt-up door for a building having a door opening to be closed by a door, the door having a vertical closed position and being movable in an opening cycle to a generally horizontal open position and being movable in a closing cycle from the open position to the closed position, the door having dimensions that are substantially equal to or slightly smaller or slightly larger than the door opening to permit the door to be installed within said opening, or to close over said opening, said system comprising:

a. a door frame including at least top and bottom horizontal members, at least two vertical side members connected to the top and bottom horizontal members at opposite ends of the top and bottom horizontal members and a barrier affixed thereto:
b. a pivot point affixed to each of the at least two vertical side members and positioned between the top and bottom horizontal members of said door frame, said pivot point engaged with an actuation mechanism which when powered raises or lowers each said pivot point;
c. first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each said cam 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 member, and to the vertical member to which it is fixed at its proximate end, thereby causing each cam follower to ride within each said cam, to guide the door as it is lowered into its substantially vertical substantially closed position, or as it is raised into its substantially open, substantially horizontal position;
and
d. at least one actuation mechanism which, when powered, causes each said pivot point to be vertically raised or lowered, thereby causing the door to open into its horizontal position by each cam follower following each said cam, and to be lowered into its vertical closed position, also by each cam follower following each said cam.

2 more elements

A method for closing a building having a door opening to be closed by a door, comprising:

a. providing a door having a vertical closed position and being movable in an opening cycle to a generally horizontal open position and being movable in a closing cycle from the open position to the closed position, the door having dimensions that are substantially equal to or slightly smaller or slightly larger than the door opening to permit the door to be installed within or over said opening, said door comprising:
b providing a door frame including at least top and bottom horizontal members, at least two vertical side members connected to the top and bottom horizontal members at opposite ends of the top and bottom horizontal members and a barrier fixed thereto;
c. providing a pivot point affixed to each of the at least two vertical side members and positioned between the top and bottom horizontal members of said door frame, said pivot point engaged with an actuation mechanism which when powered raises or lowers each said pivot point;
d. providing first and second cams, each connected to one of the at least two vertical side members of said tilt-up door, each said cam 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 member, and to the vertical member to which it is fixed at its proximate end, thereby guiding the travel of the door as it is moved between its substantially open substantially horizontal position, or as it is lowered into its substantially vertical substantially closed position;
and
e. providing at least one actuation mechanism which, when powered, causes each said pivot point to be vertically raised or lowered, thereby causing the door to open into its horizontal position by each cam follower following each said cam, and to be lowered into its vertical closed position, also by each cam follower following each said cam.
