Abstract: A rail car extension system including a first main rail section, a second main rail section and a plurality of bow structures. The first main rail section is mounted with respect to an upper surface of the first side wall. The first main rail section includes a first upper rail portion and a first lower rail portion that extends from the first upper rail portion. The second main rail section is mounted with respect to an upper surface of the second side wall. The second main rail section includes a second upper rail portion and a second lower rail portion that extends from the second upper rail portion. The plurality of bow structures are each attached to and extend between the first main rail section and the second main rail section.

Abstract: A fastening system for a flexible cover system for a truck box includes a first fastening means on the side edges of the flexible cover and a second fastening means that releasably engages with the first fastening means. The second fastening means comprises a fastening surface disposed on an elongated slat, and is slidingly received in channel portions of side rails mounted on the side of the truck box. The first fastening means can be one member of a hook and loop type fastener and the second fastening surface can be the mating member of the hook and loop type fastener. The elongated slat may also be shorter than the channel portions of the side rail to permit the slat to slide within the channel during operation of the cover system.

Abstract: A flexible cover system for a truck box includes a tension control assembly that allows both manual and automatic control of the tension of the flexible cover when covering the truck box.

Abstract: A fastening system for a flexible cover system for a truck box includes a first fastening material on the side edges of the flexible cover and a second fastening material that releasably engages with the first fastening material. The second fastening material comprises a fastening surface bonded to a substantially rigid elongated slat, and is slidingly received in channel portions of side rails mounted on the sides of the truck box. The first fastening material can be one member of a hook and loop type fastener and the second fastening material can be the mating member of the hook and loop type fastener.

Abstract: In a tarp system used to cover an open container such as a truck, the tarp being connected on one longitudinal edge to a roll bar, an improved mechanism for assisting movement of the roll bar comprises one or more constant force springs, each spring attached at one end to a longitudinal side of the container and at the other end to a reel mounted on the roll bar. When the roll bar is at one side of the container, the tarp is rolled around the roll bar and the constant force springs are extended. As the bar rolls across to the opposite side, the tarp is unrolled to cover the container opening, and the constant force springs wind into a coil around the reel.

Abstract: A connector is provided between a bow end and a cable system that moves the bow across the opening of a container or truck box. One end of the connector is adapted to mate with the end of the bow. The other end of the connector has a bore through which the cable passes. A first open slot in the connector communicates with the bore and is oriented transversely of the bore. A second open slot extending through a first side of the connector communicates with both the bore and the first open slot and opens in a first direction relative to the connector. A third open slot extending through a side of the connector opposite the first side communicates with both the bore and the first open slot and opens in a second direction relative to the first direction. The connector may be conveniently attached to the cable by passing the cable through the first slot into transverse alignment with the bore to the point where it is parallel to the transverse slots.

Abstract: A mechanism for assisting the rolling or unrolling of a tarp on a roll bar over the top opening of a trailer, container or similar structure. The mechanism includes an elongated, C-shaped housing, pulleys mounted at opposite ends of the housing, an elastic cord that is secured to the housing and passes about the pulleys, and a strap attached to the opposite, free end of the elastic cord for engaging an end of the roll bar. The housing, pulleys and cord are arranged so that the cord is extended when the tarp is in the open position, urging the active end of the crank to the closed position during the rolling step. The elastic cord pulls against movement at the active end of the roll bar when the bar is unrolled from the closed position to the open position.
