Abstract
An operator (10, 210) for moving in upward and downward directions a sectional door (D) having a counterbalancing system (30) including a drive tube (31) interconnected with the door comprising, a reversible motor (41), selectively driven in two directions by the motor, a driven gear (54) freely rotatably mounted on the drive tube and engaging the drive gear, a slide guide (56) non-rotatably mounted on the drive tube, a disconnect (70) mounted on the slide guide and selectively movable between a first position rotatably connecting the driven gear and the slide guide and a second position disconnecting the drive gear and the slide guide, and an actuator (80) for selectively moving the disconnect between the first position and the second position.
Claims33
An operator for moving in upward and downward directions a sectional door having a counterbalancing system including a drive tube interconnected with the door comprising, a reversible motor, a drive gear selectively driven in two directions by said motor, a driven gear freely rotatably mounted on the drive tube and engaging said drive gear, a slide guide non-rotatably mounted on the drive tube, a disconnect mounted on said slide guide and selectively movable between a first position rotatably connecting said driven gear and said slide guide and a second position disconnecting said drive gear and said slide guide, and an actuator for selectively moving said disconnect between said first position and said second position.
An operator according to clam 2, wherein said actuator includes a pull handle and a cable operatively interconnected with said disconnect.
An operator for moving in upward and downward directions a sectional door having a counterbalancing system including a drive tube interconnected with the door comprising, a reversible motor, a drive gear selectively driven in two directions by said motor, a drive gear, a driven gear freely rotatably mountable on the drive tube and engaging said drive gear, a slide guide non-rotatably mounted on the drive tube, a disconnect mounted on said slide guide and selectively movable between a first position rotatably connecting said driven gear and said slide guide and a second position disconnecting said drive gear and said slide guide, and a gear housing supporting said motor for moving between a door operating position and a door locking position.
A system for raising and lowering a sectional overhead door between an open position and a closed position comprising, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, and at least a portion of said operator motor assembly moveable between a door operating position and a door locking position.
