| 049322000 | WITH SAFETY BRAKE OR CATCH | 6 |
| 20080256867 | Window regulator having an attitude adjustment mechanism - A window regulator includes at least one rail and at least one movable carriage for attachment to a movable window, each movable carriage movably attached to a respective rail for movement along the rail. A driving mechanism is attached to the movable carriage for moving the movable carriage along the rail in a regulated manner. An adjustable stop is attached to the rail, the adjustable stop positioned to engage a portion of the respective movable carriage/window assembly attached to that rail, to prevent further movement of the movable carriage/window assembly in one direction. | 10-23-2008 |
| 20100005723 | CONTROL SYSTEM AND TEST RELEASE DEVICE FOR AN OVERHEAD DOOR - An overhead door control system includes an input shaft drivably connected to an overhead door axle and a load brake shaft drivably connected to the input shaft. The control system includes a load brake which releases the load brake shaft in response to rotation of the input shaft. The load brake engages the load brake shaft in response to the rotation of the input shaft being driven to zero. | 01-14-2010 |
| 20120186158 | DOOR DRIVE DEVICE HAVING TRACTION MEANS MONITORING AND DOOR PROVIDED THEREWITH - The invention relates to a door drive device ( | 07-26-2012 |
| 20120279131 | SAFETY DEVICE FOR A MOVABLE BARRIER - A safety device is provided for an upward acting door supported by a support cable, the door being movable along a pair of parallel tracks between an open position and a closed position. The safety device includes a brake pad mechanism disposed within at least one of the parallel tracks and coupleable to the door, the brake pad mechanism operable between a released position, to enable movement of the door as the door is positioned between the open and closed positions, and a braking position, to resist movement of the door. The support cable is coupled to the release mechanism such that in the event of a loss of tension of the support cable, the release mechanism actuates from the released position to the braking position to resist movement of the door. | 11-08-2012 |
| 20130283696 | CASEMENT WINDOW FALL PREVENTION DEVICE WITH AN EMERGENCY ESCAPE RELEASE MECHANISM - A casement window opening control fall prevention device having an emergency escape release mechanism. The device includes a limit arm of selected length having a pivotal connection at a proximal end secured to the casement window frame and a roller at its distal end received and confined for travel in a track secured to the casement window sash. An outer limit stop is provided in the track and positioned to stop the roller at an outer sash opening limit position in the track to thereby prevent a child from falling through the window opening. An escape disengagement opening is provided in the track for escape through the window opening in an emergency. This escape disengagement opening is positioned outwardly in the track beyond the outer limit stop and is dimensioned to pass the roller to thereby disengage the roller from the track by forcing the roller beyond the outer limit stop and through the opening with hand manipulation of the limit arm. | 10-31-2013 |
| 20160115727 | OPENING/CLOSING MECHANISM EQUIPPED WITH A SELF-LOCK DEVICE - The present invention relates to an opening/closing mechanism equipped with a self-lock device; the opening/closing mechanism includes a baseplate( | 04-28-2016 |
