Abstract: A prefabricated post and beam lean-to or free standing structure, incorporating a self-aligning, load bearing mortise and tenon joint assembly which results in a mitred joint with no visible hardware when fabricated. The structure is formed from a plurality of post and beams arranged in spaced, parallel, vertical and inclined. Attitudes extending from a lower support surface at the base of the post, with the inclined beams attaching at a higher support surface. The prefabricated sloping mortise in the post allows the beam's prefabricated tenons to be modified, on site, to descend further into the sloping mortise channel enabling the slope to be adjusted. This frame system then supports single or double glass or other sheets of material for lateral support over the enclosure.

Abstract: A plug for sealing holes in concrete to prevent ingress of water and/or vapor, especially after chemical treatment for termites. The plug has a cylindrical, tapered plug body and a sealing lip flaring outwardly at the top end. The plug is fabricated of plastisol with a durometer in the range 75-80, and includes a mold release (polypropylene clylo) to aid in insertion and a fungicide (10,10,-oxybisthenoxarsine) to prevent growth of mold and algae which compromise the seal.

Abstract: A poured concrete modular element is disclosed for supporting a roof or the like whereby a plurality of the modular elements may be interconnected in a novel manner and connected with the covering to form a monolithic element. The modular element comprises a rectangular shaped member having side faces of substantially equal length whereby the corners of the side faces are each provided with circular concave inwardly recesses. Extending outwardly from the recesses are circular members. Approximately centrally located in each side face are two vertically spaced holes and centrally disposed openings are provided in each recess. The modular elements may be interconnected at their corners by inverting one element with respect to the element and placing a fastening element through the then aligned openings. Concrete may be poured in the cylindrical opening formed by the corners of two adjacent modules to connect together the modules.

Abstract: A pair of vertically oriented hook seals positioned in facing relation on the lateral portions of a loading dock shelter engage the aft lateral portions of a truck or van positioned adjacent to a loading dock and seal the gap between the truck sides and its open doors. Each seal is coupled to a dock shelter side panel and extends inward toward an aperture in a wall about which the dock shelter is disposed. Each seal is comprised of a curtain having a plurality of spaced, resilient, flexible ribs or reinforcing strips disposed along the length thereof and securely coupled at their respective outer ends to a dock shelter side panel. The inner end of each of the reinforcing strips is coupled to an elongated foam strip extending substantially the full height of the dock shelter sides and having a generally triangular cross section.

Abstract: This invention provides a sun shield for automobiles. The sun shield has a collapsible framework for supporting a flexible cloth. The framework has at least three legs radially and isometrically extended from the framework. In the free end of each leg there is a sucker adapted to attach to the roof of an automobile. Therefore, the cloth can be easily mounted above an automobile to shade it from the unpleasant and damaging effects of the sun's rays, and it can also be easily detached from the roof of the automobile and folded into the trunk of the automobile.

Abstract: Portable awning apparatus for temporary attachment to uprights such as tree trunks or the like. The awning apparatus includes a triangular frame having a pair of side members which enclose a tree trunk, and an end member spaced outwardly from the tree trunk. A support member interconnects the two side members at a selectively adjustable distance from the apex of the triangular frame, thereby accommodating tree trunks of different sizes and permitting adjustable tilt of the awning on the tree trunk. A flexible cover extends backwardly from the end member and secures to the tree. The entire awning folds to a relatively compact and easily carryable package when not in use.

Abstract: A frame for a shelter, a shelter and structural members used to make the frame are provided. The structural members are cruciform in cross section and have swivel means which are used to connect structural members to other structural members to construct the frame of the invention. The swivel means used can be of several different types. The swivel means on the structural members make it possible to fold a frame constructed from the structural members into a small package. The structural members can be uniformly constructed, their function in the frame depending on where they are used in the frame and the particular swivel means used in their attachment. A covering is used to cover the frame and the frame and the covering together represent the shelter of the invention.

Abstract: A portable shelter structure (10) of variable size consisting of an even number of individual, folding, modular units (12) which, in their folded condition, serve as shipping containers for the shelter. Rigid floor and rigid sidewall sections (22, 28) are hinged (24) along an adjacent edge allowing rotation of the sidewall section from a closed position to an upright position so that the sidewall is substantially perpendicular. Collapsible roof support beams (72) and flexible, collapsible roof covering units (14) are stored in a cavity created between the floor (22) and sidewall (28) sections when they are in their closed state. Collapsible end walls (16) having a door structure (17) therein can be stored in the modular unit cavity or in a separate vestibule packing unit (18) which attaches to the end wall as a separate closed space outside the end wall door.
