An accessory door panel for a utility vehicle provides a fabric door panel which can be quickly deployed and installed within a utility vehicle for emergency weather use where the utility vehicle has had the factory doors removed at the discretion of the driver. The fabric door panel is fitted to the contours of the door opening and may be stored from an overhead horizontal support member over the door or alternatively stored within a container mounted to the floor at the bottom of the door opening, the door being made of a flexible material that can be stretched across the door opening and anchored at several points along the door frame by independent anchors.

A door opening system for a merchandise container comprising a plurality of bay doors, the door opening system comprising a wheel in frictional contact with a bay door of the plurality of bay doors; and a motor connected in driving arrangement with the wheel. The motor drives the wheel to rotate and thereby to control a movement of the bay door of the plurality of bay doors between a closed position and an open position.

The present invention concerns a housing (1) for the transportation of a cargo, such as truck trailers, housings mounted on the chassis of a truck, or shipping containers. The housing of the present invention comprises: (a) walls (1R) defining a closed inner space (1i), (b) an opening (2) provided in one of the walls, and further comprises a rigid door comprising one or more rigid panels (3) which are movable to seal or unseal said opening (2); (c) a flexible fast door comprising a motorized driving mechanism (10) suitable for moving a leading edge (4L) of a flexible shutter (4), wherein the flexible shutter (4) comprises two lateral edges engaged in parallel guiding rails (7) fixed to two parallel and opposite edges of the opening (2), wherein the rigid panel (3) and/or the parallel edge of the opening (2) is provided with a groove to accommodate the guiding rails (7).

A retractable trailer enclosure system includes a flexible cover, rotatable winding spindle moveable by way of a spindle guide assembly. The spindle guide assembly includes a drive assembly actuable to rotate the spindle, a shuttle assembly mounting a spindle end and a guide track assembly which guides the shuttle assembly in reciprocal movement along both a vertical cover deployment/retraction path, and laterally along a spindle storage path.
