Abstract
An essentially rectangular, flat, foldable building structural panel has a series of horizontal and oblique flexible joints made of silicone rubber impregnated fabric located on the inside of the panel. The horizontal and flexible joints create a series of geometric triangles that can be formed and folded into multiple configurations. The geometric configurations are composed of rigid triangular facet sections and flexible joints between adjacent edges of the triangular facet sections. Alternating the direction of the folds allows the user to create a three- dimensional freestanding structure of various dimensions and geometric configurations. Poles can be included for the purpose of raising the structure to produce a canopy. Since the triangular facets are rigid and the joints between the edges of the facets are flexible, quick erection of the structure may be accomplished. The structure is fastened to the ground by use of ground grommets and stakes. The panel consists of laminations of various fabrics, adhesives and triangular panel facets with fasteners and loops for stiffing rods and tension lines.
Description
FLAT FOLDABLE BUILDING STRUCTURAL PANEL
BACKGROUND OF THE INVENTION
[0001] This invention relates to the field of temporary building structures. More particularly, a flat, foldable building structural panel is disclosed which may be configured into various types of portable building structures.
[0002] In the building structure industry, many different types of building methods are available. For example, a structure such as a garage may be built upon a concrete foundation. A wood structure is then built up and a roof is attached. This is a permanent type of building structure.
[0003] Another type of building structure is the prefabricated garage or home.
These homes are built in prefabricated sections and may be erected by connecting the prefabricated sections together. Yet another type of building structure is found in the corrugated metal industry. Prefabricated roofs may be attached to vertical poles to create a simplified structure. Other types of structures could include tents, cabanas, or carports.
[0004] In the construction industry, it would be advantageous to find a simple, foldable panel that could be arranged in a manner so as to create an overhead structure. Samples of these structures could be in the form of a garage or carport, in the form of a tent, or in the form of a cabana or other structure. It is a primary object of this invention to provide a foldable and flexible flat panel that may be shaped to form a structure that is quickly and economically erected.
[0005] One problem with the construction of a house, prefabricated garage, or corrugated carport is that these structures require trucks and heavy equipment to move and erect the buildings. It is another object of this invention to provide a flat, foldable building panel that may be easily transported to the job site and that may be easily erected into a desired form of building without using heavy equipment.
[0006] One other advantage of the instant invention lies in the adaptability of the panel. It is disclosed below that unique flat, foldable building panels may be configured in different ways to created different types of structures. It is a still further object of this invention to provide a foldable and bendable flat building panel which is multifaceted and which may be used to construct different types of building structures.
[0007] Other and further objects of this invention will become obvious upon reading below described specifications.
BRIEF DESCRIPTION OF THE INVENTION
[0008] A flat, foldable building structural panel is essentially rectangular with a height and a length. Generally, the structural panel has a series of horizontal foldable edges parallel to the length of the building panel. A series of oblique foldable edges are also prefabricated into the building panel. The oblique foldable edges and the horizontal fordable edges form a series of triangles. Since the building panel may be folded along either the horizontal or oblique foldable edges, or both, the flat panel may be configured into different types of structures, including a roof type of structure, a tent structure, a cabana, and alcove, a building, or various other types of structures. In addition to the flexible folds, a series of stabilizing grommets are located in the panel. A number of ground grommets are also available to attach the foldable panel, once fabricated into the desired shape, to the ground. The panel, once folded appropriately, may be erected using bungee or elastic cords and horizontal spacers along the top of the panel. The panels are foldable and portable and may be used for temporary structures and/or covers, for example in the camping or shelter industry, to make a playhouse, storage shed, carport or boat cover. Different types of structures may be formed form a single panel making the versatility and usefulness of the device obvious.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] A flat, foldable building structural panel is best shown in Figure 1. The panel cab be formed and folded into multiple configurations. The essentially rectangular structural panel is composed of rigid triangular facets and flexible joints between adjacent edges of the triangular facets.
[0023] The triangular panels may be made of foam, wood laminates, plastic, cloth rigidified with resin, or cardboard. This listing of components form which the panels may be formed is meant as a means of illustration only and not as limitation. Various other types of building panel composites may be utilized in practicing this invention while still keeping within the spirit and disclosure herein.
[0024] Turning to Figure 1 , the foldable flexible panel is shown. It has height dimension 1 which is usually shorter than the length dimension 2. In practice, when the structure is formed, the height dimension 1 is generally shorter than the length of the panel, although this particular shape ratio is not necessarily the configuration required in practicing this invention.
[0025] The foldable flexible building panel has a number of horizontal foldable edges 3. These horizontal foldable edges 3 are generally parallel to the length dimension 2 and are spaced at appropriate places throughout the panel as shown. Also prefabricated into the building panel are oblique foldable edges 4. These oblique foldable edges 4 cut across the panel as shown and form a series of triangles. The horizontal 3 and oblique 4 foldable edges comprise flexible joints, which may be made of silicon rubber-impregnated cloth fabric or polyurethane foam rubber. The key to the composition of the flexible joints 3 and 4 is that they are flexible yet also has a structural memory so that they are capable of holding position when formed into a structure. The stiff structural panels 5 and 6 are meant to be rigid. However, the flexible joints between the triangles 5 and 6 are meant to make the flat panel building structure stiff yet
bendable. Other material may be utilized for form the flexible foldable edges 3 and 4. However, silicone rubber- impregnated cloth fabric and polyurethane foam rubber are preferred.
[0026] The horizontal 3 and oblique 4 foldable flexible edges form a series of triangles. At each corner of the panel is a rigid right triangle 5. The other panels comprise a plurality of rigid obtuse structural triangular panels 6. The obtuse structural panels 6 consist of one obtuse and two acute angles.
[0027] One good method of describing the dimensions for the structural panels is to define the ratio of the sides of the right triangles 5. As shown in Figure 1, a 2:1 right triangle is located at each corner of the rectangle. This 2:1 ratio repeats at the four corners. The remaining triangles are the obtuse triangles 6. As best shown in Figure 1, the 2:1 corner triangle 5 has a length dimension 8 and a height dimension 7. The ratio may be varied across the length of the panel to affect various rates of bend or curvature. This length to height ratio remains constant and is 2:1. The 2:1 ratio is shown in Figure 1-3. The structure shown in Figure 2 and 3 is uniquely fabricated from the basic flat panel shown in Figure 1 having a 2:1 ratio.
[0028] Once the foldable panel has been fabricated to the desired shape, it may be erected using structural securing grommets 9 and ground securing grommets 10. Located along the central portion of the flat panel are a number of structural securing grommets 9. These structural securing grommets are utilized with the structural spacers, bungee or elastic cords and ropes to erect the panel. The erection of the structure will be shown and described later in this Specification.
[0029] As best shown in Figure 2, a typical structure may be created from the basic 2:1 panel shown in Figure 1. This structure, when erected, has rigid right triangular corners 5 secured to the ground by the ground securing grommets 10. Rigid obtuse structural panels 6 having been folded as shown, to form the structure shown in Figure 2. Spacers 18 separate the structural obtuse triangular panels 6 by utilizing grommets 9. The structural spacers 18 are shown partially in Figure 3 and will be described in more detail later in the Specification.
[0030] Turning now to Figure 4-6 as 6: 1 corner triangle ration dimension is shown. This 6:1 ratio structure has a corner triangle length dimension 12 and a height corner dimension 1 1. In this structure, the length to height ratio is 6: 1. This 6:1 ratio created taller rigid triangle corners 51 and longer (greater obtuse angle) rigid obtuse structural triangular panels 61.
[0031] As best shown in Figure 5, this 6: 1 ration structural panel can be formed to create a wider roof system. The roof system in Figures 5 and 6 is much wider than the rood system shown in the structure described in Figure 2.
[0032] Turning now to Figure 6, this 6:1 ratio structure is shown as it may be placed to created a carport or pole barn. This 6: 1 ratio structure has right triangle rigid corners 51 and long rigid obtuse structural triangular panels 61. They are attached to the pole structure 13 by means of the ground securing grommets 10. In addition, structural securing grommets 9, located as shown on drawing Figure 6, are utilized to create the geometric configuration for the roof shown.
[0033] Turning now to Figure 7, a simulated tent structure 14 is shown. This simulated tent structure may be formed from the essentially flat, foldable building structural panel shown in Figure 1 and 4.
[0034] The essentially rectangular flat panels are scalable to applications of varying sizes. The ratio of the right corner triangles 5, the distance between the horizontal lines 3 and the number, spacing and angle of the oblique foldable edges 4 determines the geometric capability of the panel structure itself. Obviously, many variations of the dimensions and formation of the rigid right triangle and obtuse structural triangular panels are well within the contemplation and spirit of this disclosure. Since the spacing, ratios and distances of the foldable edges is virtually limitless, the versatility and many applications of the foldable panels disclosed herein is practically infinite.
[0035] As best shown in Figure 8, the multiple structures that may be fabricated from the flat structural building panels may also have additional structures attached end-to-end. This, in effect, could create an infinite length of structures.
[0036] In addition to the structures already described, other typical structures may be formed utilizing the method and building materials described above. For example, a heptahedron structure 16, as shown in Figure 10, may be created from the simple flat structural panel. Likewise, a cabana type structure 17 shown in Figure 1 1 may also be constructed. The cabana structure uses a ground stake 21 at one end and a support pole 22 to support the structure.
[0037] Turning now to Figure 12, one typical upper structural support brace is shown. The upper support brace structure would be comprised of horizontal structural spacers 18. These spacers 18 have a male end and female end and may be inserted between the grommet holes 9 shown in Figure 1. The horizontal structural spacers 18 are held together in compression by an inner bungee or elastic cord 19. The horizontal structural spacers 18 are inserted through the grommets 9 by pulling the horizontal spacer handle 20 in the clockwise direction as shown by the arrow in Figure 12. When the handle 20 is positioned parallel to the spacers 18 the horizontal structural spacer elements 18 fit in between the grommets. The rigidity of the horizontal spacers 18 hold the grommets apart while the tension of the inner bungee or elastic
cord 19 pulls the spacers together. This tension and compression mechanism creates the roof system best shown in Figure 6.
[0038] Another method of erecting the structures utilizes a rigid fiberglass rod inserted through the upper structural grommets 9. A tension mechanism (such as a bungee cord) would be used in conjunction with the rod to pull the peaks of the upper structure apart.
[0039] Yet another alternative means of erecting this structure would be to utilize a rope on each and the structure (connected to a grommet 9) and tension (bungee) lines between the internal grommets. This type of cooperation between outer ropes and inner tension lines would create a structure that is quickly and easily set up as shown in Figure 7 and easily compressed for storage and portability as shown in Figure 9.
[0040] The structures may be conveniently attached to the ground using ground securing grommets 10 and ground stakes 21.
[0041] The flexible joints 3 and 4 can be pre-biased for certain applications. This pre-biasing of the flexible joints 3 and 4 could suggest the shape of the final structure, whether it is a carport, tent, cabana, alcove or other type of structure previously described. Absent pre- biasing of the structure, the final geometric configuration of the structure is limited only by the folds and placement of the user.
[0042] The structure, once erected, could also be covered with canvas, plastic, nylon or Tyvek™ (a Dupont Company product) to make the structure waterproof.
[0043] The structure may be folded in either a concave or convex orientation along the flexible joint lines to create a myriad of different types of designs and geometric structures.
