A pivotal sliding bi-fold door structure mounted in a door frame having a track slidably accommodating the bi-fold door structure. The bi-fold door structure comprising at least two door panels pivotally connected by a hinge member. The improvement comprising a bi-fold door safety wedge including a main body structure. A pair of non-parallel edges on opposite sides of the main body structure facing away from each other and extending along the main body structure and nearly intersect to form a vertex at a front portion of the main body structure. Another edge extending between the non-parallel edges at a back portion of the main body structure. An elastic strap for removably elastically securing the main body structure to the hinge member, where the removable elastic securing strap has the characteristic of adjustably positioning the vertex of the main body structure in adjacency with the hinge member when the bi-fold door structure is in an open position. A non-slip surface portion located along the main body structure co-extensive with the pair of non-parallel edges thereby aiding to maintain an operational wedge-stopped position. The removable elastic securing strap further having the characteristic of enabling manual positioning of the main body structure to a non-wedged position adjacent a front side of the door panels thereby enabling the bi-fold door structure to be movable into the fully closed position.

Bi-Fold door safety wedge

A portable building system of variable size (20) consisting of a series of individually collapsing web beam frames (22) which serve simultaneously as a support structure for the exterior covering material (30) and as a support structure for a highly adaptable interior furnishing system. Individual web beam frames (22) are comprised of multiple segments including vertically oriented outer segments (32) which have a width measured horizontally in the plane of their span sufficient to support furnishing components 26 substantially within an area directly between a pair of consecutive outer frame segments 32 in a strong and convenient manner. Additional overhead segments (34) are joined to each other and to outer segments (32) with corresponding mortise (36) and tenon (38) like surfaces for a fast and positive assembly. Purlins (24) attach to the frames, joining them in sequence. Individual bays are formed between the wide vertical outer segments (32) of any two sequential frames (22) and these bays are then easily customized with the desired interior furnishing components (26) such as desks, counters, shelves, benches, bunks, and tables. Horizontal furnishing components (26) may be optionally installed at various heights between the opposing surfaces of the wide outer segments (32) of any two consecutive web beam frames. The furnishing components (26) once installed thereby become integral to the overall structure of the building. The purlins (24) also provide support for optionally used insulating liners (44) which are independent of the primary exterior cover.

Portable collapsible building system

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.
