Abstract: A panelless shutter is provided, the panelless shutter including a window frame and a plurality of louvers horizontally mounted within the window frame in a parallel configuration, each louver having a first end and a second end. The panelless shutter also includes a louver mechanism comprising a plurality of rotatable members slideably retained within a track and a gear shaft operably coupled to each rotatable member, wherein the rotatable members are coupled to the first end of each louver of the plurality of louvers and the gear shaft rotates each of the plurality of louvers substantially simultaneously. The shutter further includes a louver retainer rotatably securing the second end of each louver of the plurality of louvers, the louver retainer allowing the rotation and vertical sliding of each louver.

Abstract: A vehicle body structure includes a side wall, a vehicle impact sensor, a window covering assembly and a control mechanism. The window covering assembly is coupled to the side wall and has a plurality of window covering members extending along a window opening in the side wall from a first side of the window opening to a second side of the window opening opposite the first side. Each of the plurality of window covering members is configured to pivot between a window exposing orientation and a window covering orientation. The control mechanism is connected to the vehicle impact sensor and operably coupled to the plurality of window covering members to rapidly move the plurality of window covering members to the window covering orientation in response to detection of a vehicle impact event by the vehicle impact sensor.

Abstract: A retracting system for flexible side walls utilized for cargo vehicles wherein the flexible side wall is attached at one end to a slidable door used to extend and retract the flexible side wall. This system provides a narrow slidable door connected to a system of pulleys and cables that maintain the slidable door perpendicular to the floor and roof of the vehicle during horizontal movement of the slidable door for closing or opening the open side of a cargo carrying vehicle. The system can incorporate a reversible motor to propel the system and move the slidable door without a pushing or pulling force rom a human operator. The slidable door is suspended from a track at the top edge of the door keeping the slidable door in alignment and decreasing rolling resistance.
