Publication number: 20220356758Abstract: Methods and apparatus to operate powered doors are disclosed. A door system includes a panel, and a track including a first track wall and a second track wall opposite the first track wall. The first and second track walls define a channel therebetween. A lateral edge of the panel is to move along the channel as the panel moves between a closed position and an open position. The door system further includes a first refeed block to be aligned with the first track wall. The first refeed block is to extend a first distance above the first track wall. The door system also includes a second refeed block to be aligned with the second track wall. The second refeed block is to extend a second distance above the second track wall. The first distance greater than the second distance.Type: ApplicationFiled: May 6, 2022Publication date: November 10, 2022Inventors: Derek Lewan, Steven Hart Campbell, Michael Moore, Thomas Jansen, Thomas Leibfried, Ryan Pfaff, Perry Knutson

Patent number: 11010997Abstract: Methods and apparatus to wirelessly interlock doors are disclosed. A door system includes a user interface to receive interlock configuration data input from a user, the interlock configuration data to define an interlock condition to be satisfied before a first door is to undergo an operation, the interlock condition associated with a current state of a second door. The door system includes a first wireless transceiver to receive a signal from a second wireless transceiver associated with a second door. The method includes a door operation controller to at least one of (1) implement the operation of the first door in response to a request when the current state of the second door satisfies the interlock condition, (2) ignore the request, or (3) not execute the operation of the first door in response to the request when the current state of the second door does not satisfy the interlock condition.Type: GrantFiled: January 6, 2020Date of Patent: May 18, 2021Assignee: Rite-Hite Holding CorporationInventors: Michael Sivill, Ryan P.

Patent number: 7757437Abstract: A horizontally sliding door includes a resilient retention system that helps hold a door panel tightly against its seals when the door is closed, and resiliently releases the door panel when an external force displaces the panel beyond its normal path of travel. If the door panel is displaced off its normal path, the resilience of the retention system or simply opening and closing the door automatically returns the panel back to normal operation. The resilient retention system can be installed off the floor, so the system avoids creating a tripping hazard and avoids being damaged by nearby vehicles.Type: GrantFiled: January 9, 2004Date of Patent: July 20, 2010Assignee: Rite-Hite Holding CorporationInventors: Peter S. Schulte, Perry Knutson, Rodney Kern, Bill Hoerner, Allan H. Hochstein

Publication number: 20100132264Abstract: An example of an inflatable seal for a door includes a bi-directional airflow pattern of frost-inhibiting heated air. The bi-directional flow pattern enables the seal's discharge opening and supply air blower to both be located well above the floor and preferably above the doorway. If the discharge opening is near the suction inlet of the blower, such an arrangement makes it possible to recover previously heated air by returning some of the warm air back to the blower. In some examples, the seal includes a supply air conduit and a return air conduit with one disposed within the other. The internal conduit may include a relatively stiff elbow to prevent that conduit from becoming kinked near an upper corner of the door.Type: ApplicationFiled: December 1, 2008Publication date: June 3, 2010Inventors: Steven Campbell, Carl David Hardison, Rodney Kern, Perry Knutson, Peter S. Schulte, Mark Ungs

Patent number: 7699089Abstract: Two or more panels of a power-operated folding door are supported by a novel articulated arm assembly that ensures that the door closes tightly against a wall-mounted seal and easily opens. The articulated arm assembly includes a connector with two spaced-apart pivot points about which two adjoining arms of the assembly can rotate as the door opens and closes. The two pivot points allow the panels to readily fold up and store more compactly when the door is open. To provide an airtight seal where two leading panels come together at the center of the doorway, one or more control mechanisms coupled to the articulated arm assembly ensure that the leading panels overlap when the door is closed.Type: GrantFiled: May 17, 2006Date of Patent: April 20, 2010Assignee: Rite-Hite Holding CorporationInventors: Perry Knutson, Mike Lamey, Mark Ungs, Rodney Kern, Bill Hoerner

Patent number: 6698490Abstract: A guiding mechanism for use in combination with an industrial door that includes an extension member extending across a doorway when the door is in a doorway blocking position is provided. The guiding mechanism includes a guard bracket extending along the doorway and having a mounting segment and a guard segment, and a track extending along the doorway and including a guideway for receiving a roller of the extension member and for guiding the roller as the door moves between blocking and unblocking positions. The track is affixedly mounted to the mounting segment such that the guard segment protects the track from an obstacle during a track impact condition.Type: GrantFiled: November 21, 2001Date of Patent: March 2, 2004Assignee: Rite-Hite Holding CorporationInventors: Bill Hoerner, Tom Jansen, Perry Knutson, Steve Lester, Ronald P.
