Abstract
A tilt-up door for a building having an opening, a pair of substantially vertically juxtaposed members, cam surfaces extending laterally from the vertical members at the upper portion and a door sized to span the opening. The door can be pivotally coupled to carriages arranged for vertical movement along the vertical members and can have cam followers extending laterally from the upper portion of the door to contact the cam surfaces. An actuator or actuators can be connected to the carriages to move the carriages along the vertical members. When the actuator or actuators are operated to move the carriages vertically along the members the cam followers can move along the cam surfaces to tilt the door to a horizontal position as the door is moved vertically upward into an open raised position.
