Abstract: A releasable connection frame assembly includes a first support having a first end. Right and left connecting plates are connected to the first end, the connecting plates have alignment guides having angular guide edges and a load axis aperture. The connecting plates are reverse images of each other. A second support has a second end, an interior, opposite sides, first and second load pin apertures, and first and second release pin apertures proximate to the second end. A quick release is disposed in the second end and has a spring, first and second prongs, first and second load pins, and first and second release pins. The load pins pass through the alignment guides to releasably engage the load axis apertures to connect the first and second supports together. The release pins permit separation of the first and second supports from an engaged configuration.

Abstract: A connection device for mobile frame structures includes a bracket on a surface having a cam shaft and a cam lock has a spiral axial slot having a locking groove and a central cam groove. A cam follower, a spring and a force stop are positioned in the central cam groove. A retention device holds the components in the cam groove. A structural support is engaged to the cam lock. An intersection between the spiral axial slot and the central cam groove has one or more detents which engage the cam follower prior to engagement of the cam lock to the bracket. The cam shaft is positioned in the spiral axial slot and the cam lock is rotated moving the cam shaft into the locking groove and depressing the cam follower relative to the spring to lock the cam shaft into the locking groove.

Abstract: A climate shelter has a cover defining a valence and a moisture diverter proximate to a horizontal support. A side panel is releasably secured to the cover under the valence. The side panel includes a slot passage interior relative to the valence. The moisture diverter has an opening, a plurality of downwardly converging passage walls, and a moisture chute extending downwardly and outwardly relative to the walls. At least a portion of the moisture chute extends outwardly through the slot passage. Moisture contacting the cover enters the opening and is directed downwardly and outwardly by the walls into the moisture chute, and then outwardly for discharge exterior to a side panel. A portion of the discharge chute is disposed between the side panel and the valence.

Abstract: Techniques are described for the production of tactile dots, tactile dot groups, and tactile identifier marks on substrates that are tactilely recognizable by visually impaired individuals. Each tactile dot can be formed individually in the substrate, for example by separately embossing each tactile dot using a single punch and die pair. By using a single punch and die pair, the size, complexity and cost of the tactile dot embossing mechanism can be reduced, and the spacing between the tactile dots can be varied.
