US Classification:
49335, 49324
Abstract:
A retrofit conversion kit for facilitating the conversion of a door operating apparatus conventionally mounted above the door, to a position mounted and anchored underground for operating a swinging door therefrom. The conversion to an anchored underground position is facilitated by incorporating positional adjustment mechanisms covering any or all possible adjustment dimensions.

Sealing Arrangement For Door Operating Apparatus Retrofit Kit
A retrofit conversion kit for converting a generally moisture intolerant door operating apparatus from overhead use to underground use and for operating a swinging door while protecting the door apparatus against moisture and dust encroachment within its underground location. The kit includes an enclosure to be mounted in a sub-floor stratum beneath a swinging door, with all of the door operating and controlling apparatus, whether electronic or mechanical, being self-contained within the enclosure. A seal arrangement provides the contamination encroachment protection while permitting access to the self-contained operating apparatus within the enclosure while the door remains in place.
A method for installing a retrofit conversion kit for converting a door operating apparatus from overhead use to underground use and for operating a swinging door while protecting the door apparatus against moisture and dust encroachment within its underground location. A seal arrangement provides this contamination encroachment protection.

Operating Assembly For Use With Automatic Sliding And Folding Doors
An operating assembly for use with a door is disclosed. The operating assembly has a motor housed in an enclosure that is positioned in a floor cavity. The motor rotates a drive spindle. An actuator assembly is attached to the floor. An actuator track is attached to the enclosure and has a slot configured to receive at least a portion of the drive spindle. A first converter is positioned at one end of the actuator track and is coupled to the drive spindle. A second converter is positioned at the other end of the actuator track. A drive element attached to a bottom surface of the door is positioned in the track. A transfer device couples the first and second converters to the drive element. During operation, the motor rotates the drive spindle and the first converter to move the transfer device to move the drive element and the door.

Abstract:
A door assembly includes a door automatically operable relative to a floor and further comprises an electromechanical power device disposed beneath the floor and providing a rotary output on a shaft. The support apparatus includes a spindle adapted to receive power from the rotary shaft beneath the floor and to extend above the floor into a coupled relationship with the door. A bearing included in the support apparatus supports the spindle and at least a portion of the weight of the door beneath the floor. The electromechanical device can be of the type commonly used in overhead systems, in which case the power device can be retrofitted with the support apparatus for disposition beneath the floor. A coupling mechanism in the support apparatus can include pulleys, sprockets and gears, and power transfer devices such as belts and chains.
