Abstract:
A device for use in maintaining a temperature in a region in a cargo area of a vehicle, said region being defined by a periphery and said vehicle having interior surfaces defining a first portion of the periphery, said device comprising:a) a roller mountable substantially transversely across the cargo area of the vehicle, said cargo area extending to a closure at an exterior opening of the vehicle; b) a sheet of material connected to said roller and configured to be rolled and unrolled from said roller, said sheet of material having a size in an unrolled state sufficient to extend substantially transversely across the cargo area of the vehicle thereby forming a second portion of the periphery, said periphery being formed by the first and second portions of the periphery, said sheet permitting the maintenance of the temperature of the air in the region; c) a rolling and unrolling device for rolling said sheet around said roller into a rolled state and unrolling said sheet from said roller into the unrolled state, said rolling and unrolling device having an electric motor which rotates said roller thereby rolling and unrolling said sheet; d) a sensor device connected to the device for use in maintaining a temperature; and e) a remote transmitting device for transmitting a signal to said sensor device when said sensor is located at a distance away from said sensor device, said sensor device being capable of receiving a signal from said remote transmitting device when said remote transmitting device is located at a distance away from said sensor device and said sensor device being capable of activating the electric motor such that the electric motor rolls and unrolls said sheet into the desired rolled state or unrolled state.
