DESCRIPTION OF PREFERRED EMBODIMENTS

Referring now to the drawings, and more particularly to FIG. 1, there is shown generally at 10 the stackable building structure frame of the present invention. It is comprised of a roof frame 11 having a rectangular outline. As hereinshown the roof frame 11 is a pitched roof frame having opposed sloped rafter members 12 interconnected together by roof brace members 13. The rafter members 12 define, with a cross brace member 14, a triangular shaped truss.
As hereinshown a reinforced connecting plate 15 is secured to opposed four corners 16 of the roof frame 11. A vertical support post 17 is secured to each connecting plate 15 by two spaced- apart connections 18 and 19 as better seen in FIG. 2. These vertical connections lie on a vertical axis with one of said connections being a pivot connection, such as connection 18 and the other connection being an arresting connection, such as connection 19.
The vertical posts 17 and 17′ secured to opposed ones of the connecting plates 15 and 15′, on opposed sides of the roof frame 11, have their pivot connection and bracing connections inverted from one another as more clearly illustrated in FIG. 1. As shown in FIG. 2, the cross brace 14 is also secured to the connecting plates 15 and 15′ at opposed ends thereof. The connecting plate is provided with pre-drilled holes 20 to permit all of these interconnections.
As shown in FIG. 1, the building structure frame may also comprise intermediate trusses and vertical posts depending on the length of the shelter to be fabricated. Bracing side wall members 21 interconnect the vertical posts together to form side wall members and to which covering material may be secured. Covering material is also securable at least on the rafters and the roof brace members 13.
With reference now to FIGS. 3 and 4 there is shown how the building structure frame of FIG. 1 is collapsed to a collapsed stackable form. In order to form this collapsed structure, the vertical posts have their arresting connections 19 disconnected whereby the posts can pivot on their pivot connections 18. This permits the vertical posts 17 and 17′ to be folded to a horizontal position, as shown in FIG. 4, whereby to constitute a folded structure with the vertical post disposed in a substantially horizontal plane and in a spaced-apart manner. Once all of these vertical posts are collapsed to this position, they are secured to one another, in pairs, by a connecting vertical leg brace 30. This leg brace constitutes an adjustable leg support brace which is placed at the bottom of the vertical posts. The leg brace 30 is provided with a foot plate 31 to rest on a ground surface. The vertical adjustable leg brace is also provided with a plurality of holes 32 to permit the height adjustment of the vertical posts. With the pairs of vertical legs interconnected together there is provided a stable compact collapsed stackable building frame structure.
In order to stack these collapsible building frames one on top of the other, a stacking corner support leg 33 is detachably secured to opposed corners 16 of the collapsed stackable structure. Each of the corner support legs 33, as better seen in FIGS. 5 and 6, have stacking connecting cup- shaped connectors 34 and 34′ secured to opposed ends thereof. These cup-shaped connectors are shaped to mate with one another, as shown in FIG. 8, when two or more of these collapsed building frames are disposed one on top of another, as shown in FIG. 8. The stacking corner support legs 33 are longer than the height of the building structure in the collapsed stackable form. Their lengths are selected whereby these frame structures are closely spaced to one another.
As shown in FIGS. 5 and 7, there is further provided forklift engaging braces 35 secured in a spaced-apart manner across the building structure when in its collapsible stackable form. These braces are disposed substantially centrally of the collapsed structure and are engageable on either side of the collapsed roof frame. These forklift engaging braces are constituted by elongated inverted U-shaped channels 36 engaged between opposed engaging brackets 37 secured to opposed outer side longitudinal frame members 38 of the roof frame. The engaging brackets 37 have a hole 39 sufficiently dimensioned to permit the passage of the inverted U-shaped channels 36 and forklift fingers of a forklift truck, not shown herein.
Referring now to FIG. 9, there is shown another embodiment of the stackable building structure frame of the present invention. As shown in FIG. 9, the roof frame 11′ is again a pitched roof frame having opposed sloped rafter members 12′ but wherein the opposed slope rafter members 12′ are interconnected together adjacent a peak end 40 thereof by a peak connecting plate 41. The peak connecting plate 41, as better seen in FIG. 10, has opposed connecting arm portions 42 and 42′ each provided with sloped outer edges 43 and 43′. Holes 44 are spaced apart adjacent the slope outer edge 43 and provides at least two connections for each of the slope ratter members 12 and 12′. As hereinshown the uppermost hole 44 constitutes a pivot connection with its associated slope rafter member 12′ when connected by bolts. The other hole 44′ constitutes a second connection spaced from the pivot hole 44 whereby to rigidly secure the slope rafter members 12 and 12′ to the peak connecting plate 41 to constitute a pitch roof frame. Accordingly, by removing the fasteners 45 and 45′ on all the pitch roof rafter members, these rafter members can then be hinged on their connection with the hole 44 to assume a substantially horizontal collapsed position as illustrated in FIG. 10 wherein the opposed slope rafter members 12 and 12′ lie in a substantially horizontal plane in end-to-end relationship.
As shown in FIGS. 10 to 12, a connecting plate support bar 50 is removably secured to the reinforced connecting plates 15 and 15′ of the intermediate triangular shaped trusses 12″ whereby to provide an interconnecting support between the connecting plates 15 and 15′ of these intermediate trusses when two or more or a plurality of the folded structures, as illustrated in FIG. 10, are stacked one on top of the other. FIG. 12 illustrates four of these structures stacked one on top of the other. Accordingly, when a stack of these collapsed structures are picked up by a forklift truck, the frame maintains a rigid stacked pack which does not collapse or undergo stress in the middle portion of the span of the collapsible frames.
Each of these connecting plate support bars 50 are constructed from a tubular frame section and defines a straight connecting end section 51 for securement to a respective one of the intermediate connecting plates 15 or 15′ which is provided with holes to receive the fasteners 52 of this straight connecting end section 51. The connecting plate support bar then defines an outer vertical upwardly extending section 53, hereinshown as an upwardly curved section and an inner support straight arm 54 extending substantially parallel to the straight connecting end section 51 and spaced a predetermined distance thereabove whereby the connecting plates 15 and 15′ of the frame positioned thereover will rest onto the inner support straight arm section 54. Although not shown, this upper arm section 54 may be provided with a longitudinal groove on the upper surface thereof whereby to locate and restrain the bottom end of the connecting plate of an upper collapsed frame positioned thereover. However, it is pointed out that the stacking corner support legs 33, when mated on top of one another, align the entire frame in position. Accordingly, the connecting plates will all align themselves vertically when the collapsed frames are stacked one on top of the other.
It is within the ambit of the present invention to cover any obvious modifications of the preferred embodiment described herein provided such modifications fall within the scope of the appended claims.
