Clamp Assembly for Deployable Curtain

An improvement for a closure of a cover system mounted on a vehicle or trailer, the closure including a cover system frame defining a rectangular access opening for access therethrough to the vehicle or trailer, and a flexible curtain extendable from the top of the frame to the bottom of the frame and having opposite sides sized to cover the access opening when the curtain is extended to the bottom of the frame, the improvement comprising:

• a clamping component extending vertically along at least one side of said curtain, said clamping component including a hinge element having a forward hinge frame fastened to the cover system frame and a rear hinge frame pivotably connected to said forward hinge frame, said forward and rear hinge frames defining a vertical cavity to receive the side of said curtain, and said forward and rear hinge frames including respective seal elements facing each other to clamp onto the side of said curtain when the hinge element is in a closed configuration, said hinge element having an open configuration in which said rear hinge frame is pivoted away from said forward hinge frame and the side of the curtain is not clamped between said seal elements;
• and
• a locking component fastened to said clamping component and including;
• an elongated hollow housing fastened to said rear hinge frame;
• a bolt assembly at a bottom end of said hollow housing, said bolt assembly including;
• a bolt housing having an elongated hollow main body with upper and lower caps at opposite ends of said main body, each cap defining a bore therethrough, and said main body defining a slot between said upper and lower caps;
• a bolt including a vertical post and a horizontal post projecting radially outward from said vertical post, said bolt disposed within said bolt housing with;
• said vertical post slidably extending through the bore in each of said upper and lower caps with a lower end portion of said vertical post projecting below said lower cap, and
• said horizontal post projecting outward from said main body through said slot, wherein said horizontal post is sized to be manually grasped to move said bolt vertically within said main body, and
• a biasing spring concentrically mounted on said vertical post between said upper cap and a pin projecting radially from said vertical post between said horizontal post and said upper cap to contain said biasing spring between said pin and said upper cap such that said biasing spring is compressed when said vertical post of said bolt is moved upward toward said upper cap;
• and
• a hasp affixed to said vehicle or said cover system frame at said access opening of said cover system frame, said hasp including a top plate defining an opening configured to receive said lower portion of said vertical post therethrough to lock said clamping component in said closed configuration.
