Description

SUPPORT STRUCTURE TO SUPPORT A GARBA BACKGROUND OF THE INVENTION The present invention relates to a structure for supporting a load and, more particularly, to a durable skate made of recyclable cardboard. Wood, metal, plastic and paper are often used to make devices that support a load. One of the least expensive and easiest materials to handle is paper. Various structures, such as corrugated cardboard, take advantage of the strength of the paper by properly forming articles to exploit the inherent characteristics of the paper. Specifically, a strip of corrugated cardboard easily bends transversely to its plane, however, the strip has resistance to tension and compression when subjected to edge pressure. A support structure, such as a shelf, can be made of paper. Normally the paper or the corrugated cardboard is cut to accommodate it across a plurality of supports. However, multiple layers of paper or corrugated cardboard must accumulate, in order to provide the desired strength. Unfortunately, this accumulated mass adds weight, size and cost to the final product and places the load traversed to the shelf plane.

Another method is to take advantage of the tensile and compressive strength of paper or corrugated cardboard under edge pressure. However, while the strength is considerably increased, in a supporting structure resulting from a solid block of paper or multiple layers of corrugated cardboard secured together with their respective edges bent towards the direction of the load, the weight and the cost of the product It is unacceptable. For example, multilayer or triple-walled paperboard, which comprises three plied or fluted layers of paper sandwiched between and secured to four flat cardboard layers, can be secured together and used to exploit the strength of the cardboard edges. See, for example, U.S. Patent No. 3,199,764. However, the disadvantages of high density, weight and cost still exist. Various support structures to support a load have taken advantage of the relatively low cost and flexible nature of the paper. However, a less dense structure is needed, with greater strength and more rigid to support a load, while maintaining low cost and light weight. For example, corrugated pallets and skids have gained considerable popularity within the industry for use in the transportation of different products. Compared to wooden pallets, corrugated pallets and skids, are lighter to transport and less expensive to manufacture them. Additionally, cardboard skids can be fragmented to be disposed of, recycled to reduce waste costs, and are not returnable to eliminate transportation costs back. Corrugated paper skates are even lighter and less expensive than cardboard pallets. As the skates do not have tablets in the bottom they occupy, less storage space and boarding, due to the advantage offered by the alternate stacking. U.S. Patent No. 4,936,229 discloses a pallet having two flat cardboard sheets separated by a plurality of individual layers of cardboard runners, which are connected to the sheets by means of an adhesive. In this design, resistance and rigidity are forgone, in exchange for simplicity and cost savings. A more intricate design is described in U.S. Patent No. 4,979,446. The 4,979,446 patent uses sheets of corrugated cardboard with holes, marks and folds to make each spar. The sheets are folded in a complicated manner to make a stringer having a vertically oriented core surrounded by alternating vertical and horizontal panels, thus covering most of the grooves that would otherwise be exposed. The stringers connect to each other to form a pallet. While the last design is stronger and more rigid than the previous one, the resulting palette is more complicated and expensive. As with the paper support structures described above, support structures made of metal and / or plastic can be found with varying degrees of strength and stiffness. The same principles apply for the exploitation of the resistance of the paper using the corrugated process, can be applied to metal and plastic. As with paper, plastic and metal can be increased and thickened to provide the desired strength. However, with this accumulation of mass comes the weight, size and cost of the final product. To keep the cost low, optimally, a support structure must have a high strength to weight ratio, which optimizes the strength characteristics of the material and minimizes the amount of material used. In light of the foregoing, there is a need for a support structure which has the strength and rigidity desired to support a load, and which is also relatively light and not costly. In particular, there is a need for a corrugated skate which has the strength and rigidity necessary to transport goods in bulk, and which is also of a relatively simple design and consequently, its manufacture is less expensive and less heavy to transport it.

SUMMARY OF THE INVENTION In accordance with the foregoing, the present invention relates to a support structure that overcomes the limitations and disadvantages of the art related thereto. The additional features and advantages of the present invention will be set forth in the following description and in part will be appreciated upon reading, or can be learned with the practice of the present invention. The objects and other advantages of the present invention will be realized and will be achieved by the support structure to support a load particularly pointed out in the written description and the claims, as well as the attached drawings. To achieve these and other advantages in accordance with the purpose of the present invention, as widely explained in its described embodiments, the present invention comprises a core of connected strips that include spacer strips of corrugated material and bent strips of laminated material. The folded strips are accommodated between the opposing spacer strips and are secured to the exposed spacer strips on the bent surfaces spaced along the bent strips. Any two of the folded strips will be secured to opposite sides and at least one of the spacer strips. The bent strips and the opposite spacer strips have edge surfaces to support the load. The edge surfaces define a plane substantially perpendicular to the bent surfaces. The spacer strips and bent strips are preferably made of corrugated cardboard, plastic, and / or metal and are bent at substantially equal intervals to form the bent surfaces along opposite sides of the bent strips. The opposing spacer strips are preferably parallel. An adhesive is applied along the bent surfaces in order to secure the bent strips to the opposite spacer strips and to hold the bent strips at a predetermined pitch angle. The pitch angle between the bent surfaces is preferably between about 30 and 150 degrees. The present invention may also include a cover substantially wrapped around the core to provide additional reinforcement and restrict movement of the strips. Preferably, the cover is secured by means of an adhesive to the core and can include a plurality of cardboard sheets or a covering board. Alternatively, the cover can be made of plastic or metal or any combination of paper, plastic and metal. In addition, the present invention can be formed into a plurality of individual cores of connected strips, including each of the cores, spacer strips of corrugated material and folded strips of laminated material. The bent strips are placed between the opposing spacer strips and are secured to the opposite spacer strips on the bent surfaces spaced along each of the bent strips. Any two of the folded strips are secured to opposite sides of at least one of the spacer strips. The bent strip and the opposite spacer strips have edge surfaces to support the load. The edge surfaces define a plane substantially perpendicular to the bent surfaces. At least two of the cores are aligned substantially in parallel and at least one of the cores is interconnected with the parallel cores, in order to provide a supporting surface therebetween. A cover is individually wrapped around a substantial portion of the cores that are connected to each other, in order to restrict the movement of the strips within each of the covers. So each of the cores that connect between them and a corresponding cover, define a combination of core and cover. The combination of interconnected cores and cover is preferably substantially perpendicular to the parallel cores. Additionally, the present invention can be formed in a core of corrugated material layers connected corrugated, each of the layers having a corrugated coating and corrugated channels having bent surfaces. The corrugated groove extends in a first direction and is connected at the bent surface to the corrugated coating. Each of the layers is adhered so that the corrugated corrugation of a layer adheres to the corrugated coating of an attached layer. The layers have surfaces in the form of edges to support the load. The edge surfaces define a plane substantially perpendicular to the first direction. It should be understood that both the above general description and the following detailed description of the invention are presented only by way of example and for the purpose of providing an explanation and that they are not restrictive of the present invention, as claimed.

DETAILED DESCRIPTION OF THE INVENTION Description of the Modality s Proferidas Now we will make detailed reference to the preferred embodiments of the present invention, of which examples are illustrated in the attached drawings. The exemplary embodiment of a support structure in accordance with the present invention is shown in Figures 1A to ID, and are generally designated by reference numeral 10. As embodied in the present disclosure and illustrated in Figure lA- , r; the support structure 10 for supporting a load includes a core 12 of connected strips 14 including the spacer strips 15 of corrugated material and at least one folded strip 18 of rolled material 10. The folded strip 18 is placed between the opposing spacer strips 16 and is secured to the opposing spacer strips on the bent surfaces 11 spaced along the bent strip 18. The bent strip 18 and the opposing spacer strips 16 have edge surfaces generally designated by the arrows A. The edge surfaces define a plane substantially perpendicular to the bent surfaces 22, as designated along the arrow B. The direction of the compression load, for which the support structure 10 is particularly well adapted, is indicated by the arrows C. spacer strips 16 are preferably substantially parallel. However, the spacer strips 16 can be curved, parallel, or a combination of both, as illustrated in Figures 2A through 2C. Although the preferred spacer strips 16 are substantially parallel, it is also contemplated within the scope of the present invention, that the spacer strips 16 may be configured in various ways, depending on the requirements of the design of the support structure 10. The spacer strips 16 and the folded strips 18 are preferably formed of corrugated cardboard. Alternatively, depending on the strength and weight requirements of the support structure to be designed and the environment in which it will be used, the spacer strips 16 and the bent strip 18 can be formed of plastic and / or metal or a combination of selected materials of plastic, paper and metal. The folded strip 18 is preferably formed of corrugated cardboard when the spacer strips 16 are made of corrugated cardboard. However, many multiple layers of paper laminate can provide the consistency and spacing to meet the strength requirements, rigidity and weight of a particular design. Another preferred multiple paper laminate for the folded strip 18 is agglomerated cardboard. The bent strip 18 can be bent at substantially equal intervals to form the bent surfaces 11 along the opposite sides of the bent strip 18. Preferably, an adhesive is applied along the bent surfaces 22, in order to ensure the bent strip 18 to the opposite spacer strips 16 and to hold the bent track 18 at a predetermined pitch angle P. Alternatively, an additional adhesive may not be necessary to secure the bent surfaces 22 of the bent strip 18 to the opposite spaced strips 16. For example, the entire support structure is made of injection molded plastic, so that the strips are integrally connected one with others. In addition, to separate the spacer strips 16 in order to provide a strong and lightweight support structure 10, the bent strips 18 narrow and reinforce the spacer strips 16 transverse to their plane. The bent strip 18 may have bent surfaces 22 that are closed folds, gradual curves or substantially planar contact surfaces, as shown in Figures 1A through ID. The pitch angle is preferably between about 30 to 150 degrees. A more preferred pitch angle P is approximately 110 degrees. However, as illustrated in Figure ID, the pitch angle P may be zero degrees if one desires a support structure 10 having portions of the bend strip 18 perpendicular to the plane of the opposite spacer strips 16. In addition, the bent surfaces 11 and the pitch angle P may vary along the bent strip 18 in order to cover the different strength, stiffness and weight requirements of a desired support structure 10. Figure 3 shows another embodiment of multi-layer support structure having a thin rectangular shape. This particular mode is similar to one typically used for shelves or planks. As illustrated in Figure 4, a cover 24 can be wrapped substantially around the core 12 to further reinforce and restrict the movement of the strips. Preferably, the cover 24 is adhesively secured to the core 12. The cover 24 may include a plurality of cardboard sheets or have at least one sheet of cover board. Alternatively, for cosmetic reasons, a light weight or coating cover may be added. Alternatively, cover 24 can be formed of a material selected from plastic, paper and metal or any combination thereof. For a metal support structure, such as a composite aluminum foil or sheet, instead of an adhesive, a welding process can be used to secure the strips together. For a plastic support structure, the bent strips can be pre-heated to join them to the spacer strips. A plastic cover can be especially useful in an environment where moisture would otherwise degrade the structural integrity of a cardboard core of spacer strips 16 and bent strips 18. A preferred support structure 10 for supporting a load includes a plurality of individual cores of connected strips 14. Each of the cores 12 includes spacer strips 16 of corrugated material and bent strips 18 of laminated material 10. The folded strips 18 are placed between the opposing spacer strips 16 and secured to the opposite strips jjpaciadoraß on the bent surfaces 22 spaced at length of each of the folded strips 18. Any two of the folded strips 18 are secured to opposite sides of, at least one of the spacer strips 16. The folded strips 18 and the opposite spacer strips 16 have edge surfaces for bear the load. The edge surfaces define a plane substantially perpendicular to the bent surfaces 22. At least two of the cores 12 are aligned substantially in parallel and at least one of the cores 12 is interconnected with the parallel cores 26 to provide a support surface therebetween. A cover 24 is individually wrapped around a substantial portion of each of the cores 28 which are connected therebetween to provide a restriction of the movement of the strips 14 within each of the covers 24. The combination of the core 28 which is interconnected and the cover 24 is preferably substantially parallel to the parallel cores 26. A preferred support structure 10 formed of corrugated cardboard, uses sixty-nine pound cardboard to make the corrugated cardboard of the spacer strips 16. A folded strip 18 formed as preferred of corrugated cardboard, you can use sixty-nine-pound carton as well. However, the preferred groove of the spacer strips 16 is a groove b, while the preferred groove of the folded strips 18 is a groove e. The opposing spacer strips 16 are preferably separated by 0.7 inches. A twelve-inch segment of a preferred support structure may include spacer strips 16 having a length of twelve inches and a folded strip 18 with an approximate length of eighteen inches when flat drawn. A preferred application of the support structure 10 for supporting a load is a skid, as illustrated in Figure 5. A skid includes a plurality of individual cores 12 of paper strips 14 connected as defined in the previous paragraph. In the skate of Figure 5, the corrugations 30 of the lower cores 26 define a first direction of the groove F and the corrugations 30 of the upper core 28 define a second direction S of the groove. The first and second directions of the groove F, S, are substantially perpendicular. In operation, a section of eighteen square inches of the skate shown in Figure 5 has the capacity to support more than four thousand two hundred pounds of weight. Two parallel nuclei were tested 26 which were two and a half inches wide by four inches high. The parallel cores 26 included four spacer strips 16 having three folded strips 18 placed between and secured to the sparring strips 16. The two connecting cores 28 included seven spacer strips 16 with six folded strips 18 placed between and secured to the strips. spacer strips 16. The present invention has utility in a wide variety of support structures. For example, as illustrated in Figures 3, 6, 7 and 8, support structures incorporating features of the present invention may include shelves, pallets, tables and chairs, to name a few applications. The support structure may include three spacer strips 16 of substantially parallel corrugated material and bent strips 18 of laminated material. At least one of the folded strips 18 is interposed between each of the spacer strips 16. The folded strips 18 are secured by means of an adhesive to the spacer strips 16 on the bent surfaces 11 spaced along the folded strips 18 The selected bent strips 18 are secured along opposite sides of at least one of the spacer strips 16. The spacer strips 16 and the bent strips 18 have edge surfaces to support the load. The edge surfaces define a substantially substantial plane perpendicular to the bent surfaces 22. The present invention makes possible the construction of a durable support structure, which is made of strips of corrugated material and a folded strip of laminated material. The resistance and the weight of the corrugated material itself can be increased or decreased according to the needs of the user. The folded strip can have a number of laminated layers, changed by means of the modification of the type of material used or by the modification of the thickness of the material according to the desired application. The amount and thickness of the cores and the choice of the materials of the spacer strips and the folded strip together with the cover may vary. The present invention provides an easy and quick way to change a support structure in its size, weight, strength and stiffness to cover the requirements of the loads that are to be placed on it, simply by modifying the selected materials, adding or removing layers of the cores, adjusting the number of said cores and adjusting the cover sheets that are going to be added. The present invention provides a support structure with reduced weight and increased strength characteristics, using the edge strength of the selected material in a geometric configuration that exploits the strength characteristics of the rebar beyond those known in the art. Although the present description has been illustrated and described by means of a preferred embodiment of the present invention, according to how it has been considered at this moment, those led in the art should understand that various changes and modifications and equivalents can be made to it. they can be replaced by elements thereof, without departing from the true scope of the present invention. Therefore, it is intended that the present invention not be limited to the particular embodiment described herein, but that the invention includes all embodiments within the scope of the appended claims.

The edge surfaces (a) designate a plane (B) substantially perpendicular to the bent surfaces (22). The spacer strips (16) and the folded strips (18) are preferably formed from a material selected from plastic, paper and metal. The opposing spacer strips (16) may be substantially parallel, curved or of any combination of both forms, to provide a variety of desired shapes. The bent strip (18) can be bent at substantially equal intervals to form the bent surfaces (22) along the opposite sides of the bent strip (18). An adhesive is applied along the bent surfaces (22) to secure the bent strip (18) to the opposite spacer strips (16) and to hold the bent strip (18) at a predetermined pitch angle (P). A cover (24) can be wrapped around a substantial portion of the core (12) for further reinforcement and to restrict the movement of the strips (14). The cover (24) is secured to the core (12) preferably by means of an adhesive.
