The reduction of length of each horizontal member disengages each horizontal member from a frame outlining the opening. The rotation of the vertical members also frees the upper portion of the vertical members of the security structure. With the upper and side portions of the security structure disengaged from the frame, the security structure can be rotated and removed from the opening allowing egress. | 07-12-2012 |
| 20140150343 | TELESCOPING SECURITY WNDOW - A removable security structure interposed between two window configurations includes interconnecting horizontal and vertical members. One of the vertical members engages a gear junction of one of the horizontal members such that upon rotation of the vertical member, the horizontal member telescopically collapses. The reduction of length of the horizontal member disengages the horizontal member from a frame outlining an opening of the window. The rotation of the vertical member also frees an upper portion of the vertical member of the security structure. With the upper and side portions of the security structure disengaged from the frame, the security structure can be rotated and removed from the opening allowing egress. | 06-05-2014 |
| 20140373448 | Safety Gate Assembly - A safety gate is provided including a frame having two generally vertically extending pillars, each pillar having a substantially perpendicularly cross bar attached to it and extending horizontally at the bottom, and a hollow bar surrounding at least part of each cross bar. At least one of the cross bars is formed with an array of catches that cooperate with a uni-directional locking mechanism within the catched cross bar to permit linear motion of the catched cross bar within the surround bar in a single direction. The safety gate includes a cantilever foot pedal connected to the uncatched cross bar that pivots between an upward and open position and a downward and closed position to move the surround bare in relation to the uncatched cross bar and engage the locking mechanism to lock and unlock the frame. | 12-25-2014 |
| 20150089874 | SAFETY WINDOW GRID ASSEMBLY - A safety window grid assembly includes a hollow housing, a rotating shaft rotatably disposed in the housing, a cord and a locking mechanism. The cord is retractable and extendable relative to the rotating shaft to convert between a retracted state and an extended state. The locking mechanism is disposed on the housing, and includes an operating member rotatable relative to the housing, a driving member connected co-rotatably to the operating member, and a locking member. The locking member is movable between a locking position where a portion of the cord is clamped between the rotating shaft and the locking member such that the cord is not movable, and an unlocking position where the locking member is spaced apart from the cord such that the cord is movable. | 04-02-2015 |
