20100056311 | Self Adjusting Track Chain Adjustment Trolley - A self adjusting chain adjustment trolley comprising a stabilizer bar trolley assembly affixed to a chain tensioner assembly for translationally engaging a track, the stabilizer bar trolley assembly having a chain second end attachment point for engaging a chain second end; a sliding door attachment point affixed to the chain tensioner assembly for engaging a sliding door; and a track engagement assembly affixed to the chain tensioner assembly for translationally engaging the track. The chain tensioner assembly comprises a movable chain first end attachment point for engaging a chain first end and a force applicator attached thereto, such that the force applicator applies a predetermined amount of force to the movable chain first end attachment point to create a predetermined tension on the chain. | 03-04-2010 |
20100299871 | Sliding Door With Anti-Sway Trolley Assembly - The present invention provides at least one anti-sway trolley assembly used in conjunction with either a single sided partition set or sandwiched between first and second partition side in a double sided partition set. The anti-sway trolley assembly comprises a floating rod affixed at a first end to a trolley. Affixed at a rod second end is a floor contact member which provides frictional resistance to lateral displacement of the door. Each anti-sway trolley assembly rides in a chain guide and is affixed to a partition hinge rod. In this manner, a floor channel is not required to achieve resistance to lateral displacement forces. | 12-02-2010 |
20120138242 | PARTITION SWEEP ASSEMBLY - A folding accordion sweep partition assembly is presented. The partition has a plurality of partition panels, the panel having a front face, a rear face, a bottom edge, and two opposing open sided panel keyway channels. A hinge having two side walls, the side wall terminating in a hinge key hinges two panels by having a first hinge key slidably received and retained in a first partition panel keyway channel and a second hinge key slidably received and retained in a second partition panel keyway channel. The partition panel has a mounting bracket affixed to it, a bottom bracket removably retained to the mounting bracket, and a sweep affixed to the mounting bracket. | 06-07-2012 |

20130228289 | Fire and Smoke Rated Fabric Door - A vertically coiling door assembly that is used for emergency egress. The door assembly is capable of both powered and manual emergency egress upon entry into a predefined alarm state. | 09-05-2013 |
20140290878 | Overhead Door With Stacking Panels - An overhead door system featuring independent, unconnected panels is described. Each panel end is operatively carried within a pair of parallel tracks. The weight of the door decreases as the door is lifted and each panel completely disengages from its adjacent panel as it reaches the stacked position. This allows for a linear spring torque to door weight relationship requiring a very small motor compared to existing designs to provide the lifting torque necessary to operate the door. | 10-02-2014 |
20150197985 | OVERHEAD DOOR WITH LINTEL SEAL INTERFACE ASSEMBLY - An overhead coiling door which includes a lintel seal interface assembly comprising a mounting bracket and a seal material sandwiched between a top and bottom row of brush bristles. The top row of bristles is shorter than the bottom row which provides relative rigidity to the flexible seal material and maintains greater cycle life. Further described are novel insulating material placement used to seal the building structure—door gaps. In one preferred design, a hinged guide cover has a first leg geometry to engage the structure and a second leg geometry to engage the curtain guide assembly to effectively seal gaps created by various amounts of curtain guide assembly setback. | 07-16-2015 |
20150218866 | PARTITION SWEEP ASSEMBLY - A folding accordion sweep partition assembly is presented. The partition has a plurality of partition panels, the panel having a front face, a rear face, a bottom edge, and two opposing open sided panel keyway channels. A hinge having two side walls, the side wall terminating in a hinge key hinges two panels by having a first hinge key slidably received and retained in a first partition panel keyway channel and a second hinge key slidably received and retained in a second partition panel keyway channel. The partition panel has a mounting bracket affixed to it, a bottom bracket removably retained to the mounting bracket, and a sweep affixed to the mounting bracket. | 08-06-2015 |
