Disconnect for sectional door operation
First Claim
1. An operating system for controllably moving a sectional door between open and closed positions comprising:
- a counter balancing system having a drive tube interconnected with the sectional door and an operator motor mounted adjacent to said drive tube;
a drive train interconnecting said drive tube and said operator motor for selectively driving said drive tube for moving the sectional door between the open and closed positions, said operator motor having a drive shaft and said drive train including a drive gear mounted on said drive shaft and a driven gear mounted on said drive tube with said drive gear and said driven gear each having a pair of axially spaced spur gears;
a coupler in said drive train selectively retractable from a driving position; and
a remotely-actuated disconnect assembly operatively attached to said coupler, wherein said disconnect assembly retracts said coupler, whereby the sectional door may be manually moved toward either of the open position and the closed position.

a remotely-actuated disconnect assembly operatively attached to said coupler, wherein said disconnect assembly retracts said coupler, whereby the sectional door may be manually moved toward either of the open position and the closed position. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
a bracket having a first member defining a first aperture, for receiving said cable; and
a sleeve mounted on said cable adjacent said first member, wherein said first aperture is sized to receive said sleeve when said cable is pulled substantially axially.
-
-
11. An operating system according to claim 10, wherein said bracket has a second member having a second aperture axially aligned with said first aperture for receiving said cable, wherein said sleeve is positioned between said first and second members when said coupler is in said driving position.
-
12. An operating system according to claim 11, further comprising a handle coupled to a free end of said cable.
-
13. An operating system according to claim 12, wherein said handle includes a handle bracket for selectively maintaining said coupler retracted from said driving position.
-
14. An operating system according to claim 13, wherein said handle bracket is adapted for mounting in a fixed position.
-
15. An operating system according to claim 14, wherein said handle bracket has a V-shaped cable receiving aperture sized smaller than said arm, whereby said bracket stops said handle from translating toward said driving position.
-
16. A disconnect for an operator for controllably moving a sectional door between open and closed positions comprising:
-
a coupler adapted for selective interconnecting the operator and the door for moving the door between the open and closed positions when in a driving position;
a cable having a first end operatively attached to said coupler and a free end;
a sleeve mounted on said cable between said first end and said free end; and
a bracket adjacent said sleeve having a first aperture sized slightly larger than said sleeve, whereby said sleeve passes through said first aperture when said cable is pulled substantially axially to move said coupler away from said-driving position. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A disconnect for an operator for controllably moving a sectional door between open and closed positions comprising:
-
a coupler adapted for selectively interconnecting the operator and the door for moving the door between the open and closed positions when in a driving position;
a cable having a first end operatively attached to said coupler and a free end;
a sleeve affixed on said cable between said first end and said free end; and
security lock means adjacent said sleeve permitting movement of said sleeve relative thereto only when said cable is pulled substantially axially to move said coupler away from said driving position. - View Dependent Claims (24, 25)
