Overhead door locking operator
First Claim
1. 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 adapted to be freely rotatably mountable on the drive tube and engaging said drive gear, a slide guide adapted to be 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, wherein said housing is pivotally mounted for movement between said door operating position and said door locking position.

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), a drive gear (52) 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.

- 1. 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 adapted to be freely rotatably mountable on the drive tube and engaging said drive gear, a slide guide adapted to be 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, wherein said housing is pivotally mounted for movement between said door operating position and said door locking position.
- 3. An operator according to clam 2, wherein said actuator includes a pull handle and a cable operatively interconnected with said disconnect.
- 14. 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 adapted to be freely rotatably mountable on the drive tube and engaging said drive gear, a slide guide adapted to be 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, a gear housing supporting said motor for moving between a door operating position and a door locking position, and a retaining assembly to secure said motor in said door operating position during the normal operating torque range attendant the moving of the door in the upward and downward directions, wherein said motor carries a plunger which is adapted to engage a fixed stop, and wherein said plunger is spring loaded for urging said plunger into engagement with said fixed stop.
- 17. 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 sectional overhead door, an operator motor assembly adapted to be mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of said operator motor assembly moveable between a door operating position and a door locking position, wherein said portion of said operator motor assembly is adapted to engage the sectional overhead door in said door locking position, a disconnect for selectively connecting said operator motor assembly and said counterbalance system and disconnecting said operator motor assembly and said counterbalance system, and an actuator operative to both disconnect said operator motor assembly and said counterbalance system and move said operator motor assembly from said door locking position to said door operating position, whereby the door may be manually raised from the closed position.
- 26. 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 sectional overhead door, an operator motor assembly adapted to be mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of said operator motor assembly moveable between a door operating position and a door locking position, wherein said portion of said operator motor assembly is adapted to engage the sectional overhead door in said door locking position, and a switch associated with said operator motor assembly for signaling movement of said operator motor assembly from said operating position toward said door locking position when the door is not in the closed position.
