DESCRIPTION OF ILLUSTRATED EMBODIMENT The structure 10 comprises a pair of rectangular panels each designated by the same reference numeral 11 and has fastening means designated generally by the reference numeral 12 fastening associated top edge portions 13 of the rectangular panels together in a hinged manner. The fastening means 12 enables the rectangular panels to be hingedly moved or folded inwardly, i.e., toward each other, and arranged in substantially parallel relation so as to define a space S therebetween and such fastening means enables the panels 11 to be hingedly folded outwardly, i.e., away from each other, to define an inverted substantially V- shaped structure, as illustrated in FIG. 3 of the drawing.
The structure 10 also comprises a pair of triangular panels 14 and 15 hingedly attached to the rectangular panels 11. In particular, the triangular panel 14 is hingedly attached to one of the rectangular panels 11 using a plurality of spaced hinges 16 and in a manner enabling panel 14 to be folded against the inside surface of its rectangular panel 11 and as shown at 17 in FIG. 3. The triangular panel 15 is hingedly attached to the other rectangular panel 1 l by a plurality of spaced hinges 20 in a manner which enables the panel 15 to be folded against the inside surface of its rectangular panel 11 and as shown at 21 in FIG. 3. Thus, once the rectangular panels 1 1 with panels 14 and 15 held against their inside surfaces are hingedly folded inwardly about the fastening means 12 to define the configuration illustrated in FIG. 2, the triangular panels 14 and 15 are received within the space S. However, as the rectangular panels 11 are hingedly folded outwardly, the triangular panels 14 and 15 are also hingedly folded outwardly about their respective hinges 16 and 20 to define the configuration illustrated in FIG. 1.
As will be apparent from FIGS. 5 and 7 of the drawing, the fastening means 12 comprises a pair of substantially identical L-shaped brackets 23 and each bracket has legs 24 and 25 which diverge from a common junction. The leg 24 of each bracket 23 is fixed to an associated rectangular panel 11 with its leg 25 extending transverse, perpendicular in this example, the leg 24 whereby each leg 25 extends substantially perpendicular its associated panel 1 1. The fastening means 12 also comprises at least one hinge device connecting the brackets 23 together and in this example a plurality of conventional hinges 26 are provided in spaced relation and hingedly connect the leg portions 25 of brackets 23 together to thereby hingedly connect the top portions 13 of the rectangular panels 1 1 together. Each hinge 26 has a pair of leaves 27 suitably fixed to the leg portions 25 and the leaves have knuckles which receive a pin 28 therethrough in a known manner.
The structure 10 also has a flexible cap 29 made of a suitable metallic material and the cap has lower edge portions 30 arranged beneath the vertical level of the fastening means 12 and such portions are suitably fixed to the rectangular panels 11 whereby the cap 29 shields the top edge portions of the panels 11, 14, and 1S and, hence, the top of the structure 10 against the elements. The cap 29 has an arcuate configuration when viewed from an end thereof and, thus, is easily flexed from the configuration shown in FIG. 2 to the configuration shown in FIG. 1 without damage thereto.
The triangular panel 14 has a side edge portion 31 which is hingedly attached by hinges 16 to one panel 1 1 and has an oppositely arranged unattached or swinging 3 side portion 32. Similarly, the triangular panel 15 has a side edge portion 33 hingedly attached by hinges 20 to the other panel 11 and has an oppositely arranged swinging side portion 34. Each swinging portion 32 and 34 is detachably fastened in position against an associated panel by a plurality or set of quick fasteners 35 of conventional construction, see FIGS. and 9. Each fastener 35 is constructed so that it is normally carried in its fastening position on an associated rectangular panel 11 and has suitable fastening means which may be in the form of a helical thread 36 which is threaded through an associated opening 38 in a triangular panel and upon turning the head portion 37 of such a fastener 35 through an angular increment of approximately 90 the thread 36 engages portions of the triangular panel adjoining its opening 38 to fasten the triangular panel in position.
To assure that the structure has optimum structural integrity, each rectangular panel 11 is provided with peripheral beams 40 at its bottom and ends while the bracket 23 also serves as a top beam. Similarly, each triangular panel 14 and is provided with peripheral beams 41.
The panels 11,14, and 15 may be made of any suitable material; however, each panel is preferably made of metallic materials containing aluminum thereby assuring that these panels have a high strength to weight ratio. In this example each rectangular panel 11 is -made of corrugated aluminum sheets 2, see FIG. 6,
while each triangular panel 14 and 15 is made of corrugated aluminum sheets 43, as illustrated in FIG. 8.
A typical structure 10 having a floor measuring 11 feet by 12 feet and a height of roughly 10 feet may be readily erected by as few as three men by first placing the structure illustrated in FIG. 2 with one of its rectangular panels 1 1 on the ground and then lifting vertically upwardly using one or more ropes, as required, attached to the cap 29 while simultaneously spreading the rectangular panels 11 apart, as shown in FIG. 3. The triangular panels 14 and 15 are then allowed to swing vertically into position whereupon the fasteners 35 are quickly fastened in the manner described previously to complete the structure. The structure 10 may be anchored to the ground using metal stakes 45 and each of these stakes may be slidably carried within one or more brackets 46 fixed to an associated panel 11 or each stake may be carried separately.
The structure 10 may be provided with one or more windows and at least one door and, in this example, a door 50 is provided in the triangular panel 14 and a window 51 is provided in the triangular panel l5.'The door is suitably framed and provided with hinges and a latch whereby it is ready for normal use.
The structure 10 may be modified to fit particular requirements. For example, the end panel 14 may be divided into two unequal portions along a vertical line slightly to the right of the door 50 as shown in FIG. 1. The two portions may be used in different ways, as follows: (i) The two portions may be hinged together so that the smaller portion may be folded against .the larger portion when the panel 14 is swung against the panel 11, and corresponding portions of the opposite panel 15 may be similarly divided, hinged and folded against the other panel 1 1; (ii) the two portions of each of the end panels 14 and 15 may be hinged not to each other but rather to the adjacent ends of the two rectangular panels 11. In a modification, which may be independent of or in combination with the first mentioned modifications, especially modifications (ii), the two rectangular panels 11 may be subdivided, such as by separating the structure 10 illustrated in FIGS. l-4 into 'two separate halves, with the plane of division passing through the middle of the structure parallel'to and half way between the end panels 14 and 15. The two halves can thus be transported separately, assembledon the site,.and. joined by any means suitable for use in the field.
