Abstract: A locking device for protecting the contents of a container from theft includes an extension member having an adjustable length and a lock for inhibiting adjustment of the extension member's length when the lock is engaged. To secure the contents of a container from theft, the locking device is installed between two opposing surfaces, such as between two vertical wall surfaces, with the extension member extending across the container door with the door in its closed position. The locking device is installed by simply inserting each end of the extension member into suitable cavities formed in the opposing surfaces, or in brackets attached to the opposing surfaces, adjusting the length of the extension member as necessary. Thereafter, the lock can be engaged to prevent adjustment of the extension member's length, and thereby prevent removal of the ends of the extension member from the surface openings.

Abstract: A dock module comprises an air-tight flotation chamber with a buoyant foam material positioned within an upper end thereof. The flotation chamber includes aperture positioned on its bottom end to permit water to enter the chamber and serve as a ballast. To float the dock module, compressed air is injected into the flotation chamber to increase the module's buoyancy and adjust its freeboard so that the buoyant foam is lifted completely above the water contained within the flotation chamber. If the air-tight flotation chamber fails, the buoyant foam will prevent the dock module from becoming submerged. Each module comprises a plurality of longitudinally and laterally extending tubes that can be used to attach the module to a like module using tubular couplers and tensioned cabling. Multiple modules can thus be joined in any desired configuration to yield a floating dock system having virtually any desired geometry.

Abstract: An improved mobile home skirting assembly includes a mounting channel with barbs projecting into the channel to engage protrusions on skirting panels inserted into the channel, locking the panels into place with the mounting channel.
