The pair of first side walls 18A and 18B and the pair of second side walls 20A and 20B are attached along the first polygonal base 12 such that the pair of first side walls 18 A and 18B are connected to the first pair of edges 14 A and 14B and the second pair of side walls 20A and 20B are connected through the transverse edges to the second pair of edges 16A and 16B.

The enclosure structure 10 may be formed from various materials such as plasticized aluminum foil, aluminum foil, material having laminate, fabric material, synthetic fabric, nylon, antistatic nylon material, plastic material, paper, cardboard etc.

Adjoining edges of side walls 18A, 18B, 20A, 20B and the edges 14A, 14B, 16A and 16B of the first polygonal base 12 may be attached by heat welding, suturing, adhesive, mechanical attachment such as fasteners, hook and pile arrangement, zipper, snap type arrangement, combination of various attachments or any other attachment arrangements known in the art.

According to some embodiments of the invention the enclosure structure 10 may be of any desired dimension and be used for various purposes such as covering machinery of large dimensions, covering a building, covering one's vehicle, a garden table etc. According to other embodiments, the structure 10 may be used as a container - 8 187015/2 and may be provided with handles, pockets, lead, covering arrangement, closing arrangement on the side walls or edges thereof, etc.

According to some embodiments the enclosure structure 10 is further provided with a second polygonal base 17 suitable for articulating to the respective edges 14C, 14D, 16C and 16D such that when an enclosure structure 10 is fitted with the second polygonal base 17 3-dimensional quadrangular structure appears. Such structure may also be considered to provide a vacuum tight structure or could for example provide liquid impermeable, heat/ resistant, UV protected structure, etc. For these purposes, the structure will be at least partially constructed from suitable material.

According to certain examples, in case the structure 10 is to be used as a vacuum tight structure, the structure 10 may further be provided with an air withdrawing /introducing valve 19 (shown in Fig.l) on one of the walls or the bases or at an intersection line of the edges of the walls or edges of the wall and the base such that easy access is provided for withdrawing the air out of the 3-dimensional structure. Such a valve may be fitted to any of the walls at any stage of manufacturing thereof.

Fig. 2A is an illustration of a first step in a succession of steps in forming of the 3-dimensional enclosure structure 10 illustrated in Fig. 1 according to one example of the present invention. Fig. 2A shows a polygonal base 12 having a first pair of opposite edges 14A and 14B and a second pair opposite edges 16A and 16B.

In the further step shown in Fig. 2B a side wall 18A is attached along the first polygonal base 12, the side wall 18A has two transverse edges 24 A and 24B and two longitudinal edges 26A and 26B. The side wall 18A is along its transverse edge 24B to the edge 16B of the polygonal base 12. In a successive step shown in Fig. 2C a longitudinal edge 26 A of the side wall 18A is diagonally valley folded along scored line 27 such that the longitudinal edge 26A interfaces with part of the transverse edge 24B of the side wall 18 A and the edge 16B of the polygonal base 12.

In a successive step shown in Fig. 2D a longitudinal edge 26B co-extends with part of the transverse edge 24B of the side wall 18A and the edge 16B of the polygonal base 12 such that an essentially triangular shape is formed upon a ply of the first polygonal base 12.

As seen in Fig. 2B the side wall 18A is longitudinally larger than the base 12, therefore when folded, a flap 35 projects below the edge 16A. In such a case, when the side wall 18A is folded as described hereinabove, a vertex indicated as 25 and the flap - 9 187015/2 are folded over along scored line 31 in a horizontal valley fold in the direction of arrow 33 such that the vertex of the flap 35 lies upon the ply of a polygonal base 12 and the horizontal fold line 31 lies away though may be parallel with respect to the transverse edge 16B of the polygonal base 12 as illustrated in Fig. 2C. According to some examples of the present invention, the flap 35 may be folded over either to lie above the remaining of the readily folded ply 18A or below the ply 18A.

As a second side wall 18B is placed over the assembly of plies of a polygonal base 12 and of the readily folded side wall 18A panels (Fig. 2F), the transverse edge 34A of the side wall 18B is placed in line with the edge 16A of the base 12 such that the edge 34A may be attached to the edge 16A. Steps described with reference to Figs. 2C-2E are now executed on the second side wall 18B (Figs. 2G-2I) with the longitudinal edge 36B being folded first to co extend along the transverse edge 16A of the base 12.

A flap 37 formed following the folding steps is folded over the horizontal line 39 in a direction of the arrow 39B to lie upon the plies of polygonal base and the two side walls as illustrated in Fig. 21.

In a subsequent step illustrated in Fig. 2J-2K, the second pair of sidewalls 20A and 20B is attached to the polygonal base structure 12. The first side wall 20B of the second pair of side walls is attached along its edge 21 A to the longitudinal edge 14B of the of the polygonal base 12 and the longitudinal edges 26B and 36A of the first 18A and second side walls 18B respectively as illustrated in Fig. 2J. In order to make possible the attachment of the second side wall 20B, edge 21B is partially folded in the direction of arrows 22A and 22B forming flaps 25A and 25B (Fig. 2K) such that the second side wall 20A may be easily attached to the longitudinal edges 26A and 36B of the first pair of side walls 18a and 18B (see Fig. 2E).

According to another example of the invention illustrated in Figs.3A-3G, a ply material is provided having a total width of 4 side walls a, b, c, and d as illustrated in Fig. 3A. In Fig. 3A, side walls a, b, c, and d are separated by scored lines 40A, 40B, 40C indicating the area where the walls will be folded along the scored lines 40A, 40B, 40C. The outer, free longitudinal edges 42 and 44 are attached to one another as illustrated in Fig. 3B. The edges 42 and 44 may be attached to one another before or after the ply is folded along the scored lines.

In a sequential step illustrated in Fig. 3C, the walls b and d are sink folded along the main central line thereof, indicated as II and 12 in Fig. 3B, such that the wall a and - 10 187015/2 wall c may be pinched together to receive a relatively flat configuration as illustrated in Fig. 3C and Fig. 3D.

The base 41 for the enclosure structure 10 according to this embodiment, separately shown in Fig. 3D, is valley folded and unfolded along both diagonals 43A and 43B thereof indicated by arrow 46 and then valley folded and unfolded as indicated by arrow 48. The base is then horizontally valley folded forming the creases 47 and 49 and a prayer fold is performed such that when three dimensionally/sink folded along the crease 49 and bringing together the angles a and β the structure illustrated in Fig. 3E is formed (also known as a waterbomb base).

In a sequential step illustrated in Fig. 3F the base 41 obtained in the previous step is introduced into the readily folded four wall structure illustrated in Fig. 3C such that an apex 45 of the base structure 41 is first inserted into the space between the wall structure in the direction illustrated by arrow 53 in Fig. 3F. The edges 50A-50D of the polygonal base 41 and the upper edges 41A-41D of the walls are then attached to each other and the formed structure in deployed configuration is illustrated in Fig. 3G.

If it is desired to obtain a sealed structure an opposite base may be provided and at least partially attached by for example carrying out steps similar to those discussed above or alternatively attached upon deployment.

Figs. 4A - 4G illustrate successive steps in the manufacturing of an enclosure structure 60 according to yet another example. As illustrated in Fig. 4A, a first side wall 68A having two transverse edges 64A and 64B and two longitudinal edges 64C and 64D is laid upon a surface and a ply of polygonal base 62 having two transverse edges 66A and 66B and two longitudinal edges 66C and 66D. The base 62 is attached to the first side wall 68A along the transverse edge 66B thereof such that the transverse edge 66B of the polygonal base 62 is attached to the transverse edge 64B of the side wall 68A. In a sequential step illustrated in Fig. 4B and as illustrated by arrow 65 the base is horizontally valley folded along mid-line thereof indicated by a scored line 67 in Fig. 4A.

In a successive step illustrated in Fig. 4C a second side wall 68B having two transverse edges 74A and 74B and two longitudinal edges 74C and 74D is laid upon the ply of a first side wall 68A and the readily folded polygonal base 62 such that the transverse edge 74A of the second side wall and the second transverse edge 66A of the polygonal base 62 are now attached. In a further step, as illustrated by arrows 69A and - 11 187015/2 69B the free longitudinal edges 66C and 66D of the polygonal base are sank or 3-dimensionally inwardly folded to receive the form illustrated by the scored lines in Figs. 4D and as best seen in Fig 4E.

The step of folding base 62 may alternatively be performed before the second side wall 68B is attached or alternatively, the base may be folded separately from the walls and attached to the first side wall 68A in a readily folded configuration.

The perspective view of the plies of the first side wall 68A and the second side wall 68B with the attached thereto and folded therebetween polygonal base 62 is illustrated in Fig. 4E.

The structure is then flattened as illustrated in Fig. 4F and in order to receive the second pair of side walls 65A and 65B, the side wall 68A is vertically valley folded along the scored lines 71A and 71B which extend between the edges 64A and 64B of the second side wall 68A. According to this example, the scored lines are located at a certain distance X/2 from the edges 64C and 64D (X being the width of the polygonal base as shown in Fig. 4A). The longitudinal edges 11, 12 and 13, 14 of the second pair of side walls 65A and 65B are attached to the longitudinal edges 64C, 74C and 64 D and 74D of the first pair of side walls 68A and 68B respectively. In Fig. 4H shows the erected structure 60.

According to yet an example of the invention, illustrated in Fig. 5A, a side wall 80A of a first pair of side walls is placed on a flat surface and a second pair of side walls 82A and 82B are attached to longitudinal edges 83C and 83D of the first side wall 80A such that the width of the each one of the second side walls is of the same / shorter width than the width the first side wall 80A.

The side wall 82A has two transverse edges 84A and 84B and two longitudinal edges 84C and 84D and the side wall 82B, has two transverse edges 85A and 85B and two longitudinal edges 85C and 85D.

The second pair of side walls 82A and 82B are folded along the central longitudinal line indicated by scored lines 81A and 81B such that the second side wall 80B may now be mounted such that the longitudinal edges 85C and 84C of the second pair of side walls 82A and 82B may be attached to the longitudinal edges 83C and 83D of the first side wall 80A and the longitudinal edges 85D and 84D of the second pair of side walls are attached to the longitudinal edges 86C and 86D of the second side wall 80B. - 12 187015/2 In Fig. 5D the base 87 according to this example may be folded using the steps of a prayer fold or by simply horizontally folding the base 87 along the scored line 88 and sinking the longitudinal edges 89A and 89B thereof substantially as illustrated in Fig. 5D.

Similar process of wall folding can be performed on any number of even or odd number of second pairs of side walls. For example, if an octagonal structure is desired, two side walls of the first pair of side walls will be left unfolded and six side walls will be horizontally valley folded, with half of the side walls, namely three side walls, placed to coextend with the edge 83D and the second half with the edges corresponding the edge 83C, such that two bellow like structures are constructed on the first side wall and the second side wall of the first pair of side wall will now be attached to the uppermost free edges of the sidewalls of the second pair of side walls. Similar process can be performed for any desired number of side walls.

Reverting to Fig. 5C there is illustrated a perspective view of the semi-deployed four wall structure. In order to attach the polygonal base 87 to the wall structure, the folded polygonal base structure is introduced with the fold line 55 thereof leading into the enclosed side wall structure obtained at the step illustrated in Fig. 5C as illustrated by arrow 93 and a polygonal base 87 is then attached to the corresponding edges of the first and second pairs of side walls.

When erected, the enclosure structure takes the form as illustrated in Fig. 1.

According to yet an embodiment of the invention a process of manufacturing a 3-dimensional enclosure structure is illustrated in Figs. 6A through Fig. 6G.

According to this example, a first side wall 102 A has two transverse edges 104 A and 104B, and two longitudinal edges 104C and 104D. To the transverse edge 104A a polygonal base 110 is attached trough its transverse edge 112A and folded along the scored line 91 in a horizontal valley fold in a direction of arrow 95 in Fig. 6B. In a further step shown in Fig. 6C a second side wall 102B is laid upon the ply of a first side wall 102 A and a readily folded polygonal base 110 and the transverse edge 106 A of the second side wall 102B is attached to the transverse edge 112B of the polygonal base 110.

Such wall and base structure may further be achieved by folding at least one ply of material having a total length comprised of the length of the at least one side wall and - 13 187015/2 the base. In such a case, at least one fold is made to divide the ply to the at least one wall and the base as illustrated in Fig. 6D or alternatively in Fig. 6E.

In order to attach the second pair of side walls 108A and 108B to the structure, a second pair of side walls are folded along the longitudinal mid-line thereof in a direction indicated by arrow 97 along the scored line 98.When in a folded configuration the one corner of the now folded side wall is sunk in through a 3-dimensional folding along the scored line 99 illustrated in Fig. 6F such that an inclined edge appears when the side wall is in a folded configuration. In a sequential step illustrated in Fig. 6F the second pair of side walls are introduced into the structure of the two side walls 102A and 102B and a polygonal base 110 as indicated by arrows 101A and 101B.

In a sequential step the longitudinal edges of the side walls 104C and 106C and 104D and 106D are attached to the edges of the second pair of side walls and the longitudinal edges 112C and 112D of the base 110 are now attached to the transverse edges of the second pair of side walls 108A and 108B.

If the enclosure structure is to be stored, stacked and/or transported, the above described and exemplified structures in their flat configurations are further folded by regular folding steps further comprising at least one transverse folding step to fold the structure on transverse fold to reduce longitudinal length, and at least one vertical folding step to fold the structure on longitudinal folds to reduce transverse width, all steps may be preformed in a random order (as seen in Figs. 7A-7C).

In Figs. 8A to 8E steps of manufacturing a structure having triangular facets are illustrated. According to this example, a first side wall 200 having two edges 202 and 204 and a base edge is placed on a surface and side walls 220A and 220B from second pair of side walls are sequentially attached to the edges of the first side wall 200 along their edges 222A and 224A and folded each one in its turn along the scored lines 240 and 260 respectively (see Figs. 8B and 8C).

A second side wall 230 is then attached to the edges 222B and 224B and a 3-dimensional pyramidal structure is formed as the folded model is erected (Fig. 8D). If a base is needed to enclose the structure, a base 800 (Fig. 8E) is folded to a waterbomb base structure, e.g. as described above and along the scored lines illustrated in Fig. 8E.

According to another example of the invention, the base in the above described examples may be folded separately from the walls if desired and attached to the side wall in a readily folded configuration.
