FIG. 2 is a sectional view 2-2 of FIG. 1, and FIG. 3 is a detailed sectional view 3-3 of FIG. 2. In various embodiments, sports board may be used, for example, for gliding over the snow or a slippery surface, or may be used to float on water. Sports board 100 includes handles 105 that are fastened to board 102 using pins 107 and which are accessible from top surface, and rails 109 that protrude from bottom surface 103. Methods for attaching or incorporating rails and handles into sports boards and known in the art. In the embodiment of FIGS. 1 and 2, handles 105, pins 107, and rails 109 are formed from high-density polyethylene (HDPE).
Board 102 includes top and bottom layers that may include graphics. Thus, for example, board 102 may include one or more foam and/or plastic materials and markings which may include printed or transferred graphic images that are visible on top surface 101 or bottom surface 103. In several embodiments, board 102 includes a core between a top layer and a bottom layer, where one or both of the top or bottom layers support graphics visible from top surface 101 or bottom surface 103. In one embodiment, a graphic layer is covered with a clear layer which may, for example form one or both of top surface 101 or bottom surface 103. In another embodiment, a graphics layer is printed directly onto top surface 101 or bottom surface 103. In another embodiment, top surface 101 includes a graphics layer, and bottom surface 103 may, but is not required to include, a graphics layer that is covered with a clear layer.
Board 102 may include one or more foam portions. Examples of foam material include, but are not limited to, one or more of polyethylene, cross-linked polyethylene, expanded polyethylene, expanded polystyrene, polypropylene, or a polyethylene/expanded polystyrene blend. The density of the foam portions of board 102 may be from approximately 0.75 pounds per cubic foot to approximately 10 pounds per cubic foot, and have a thickness of from approximately 1 mm to approximately 125 mm. Board 102 may also include materials covering the one or more foam portions. The covering material may include, but is not limited to, one or more of a polyethylene layer or a fabric formed of natural and/or synthetic materials and has a thickness of from 0.01 mm to approximately 2 mm.
FIG. 3A is a schematic sectional view of a first embodiment of a board 302, and FIG. 3B is an exploded view of board 302. Board 302 may be generally similar to board 102, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of FIGS. 1, 2, 3A and 3B.
Board 302 is a laminated structure that includes a core 310, a top layer 320 (also referred to herein as a “deck”) and a bottom layer 330 (also referred to herein as a “slick”). In various embodiments, core 310, top layer 320, and bottom layer 330 may also include one or more layers, including but not limited to foam layers.
In the embodiment of FIGS. 3A and 3B, core 310 has one or more layers of foam with a top surface 312 and a bottom surface 314. More specifically, core 310 in one embodiment is single layer core, and in another embodiment is a multi-layer core. Top layer 320 includes a layer of a film 321 and a graphics layer 323, where film 321 has an inner surface 324 that faces core top surface 312 and an outer surface 322 that supports graphics layer 323. A bottom printed layer 340 includes a fabric layer 331 that supports a graphics layer 333. A bottom layer 330 includes bottom printed layer 340 and a clear layer 335. More specifically, fabric layer 331 has an inner surface 332 that faces core bottom surface 314 and an outer surface 334 that supports a graphics layer 333, and clear layer 335 has an outer layer 338 and an inner surface 336 that faces graphics layer 333 and fabric layer 331.
Core 310, film 321, fabric 331 and clear layer 323 may include, but are not limited to, one or more plastic materials having the structure of a film, a sheet, or a foam, and may include plastic fibers or other materials, such as natural fibers. Graphics layers 323 and 333 include inks that are transferred to and which may cover some or all of the supporting surfaces, and which may require surface treating before being transferred. As shown in FIGS. 3A and 3B, clear film inner surface 336 may contact graphics layer 333 and may also contact fabric outer surface 334. Graphics layer 323 and any portion of film out surface 322 that does not support graphics may form top surface 101.
The facing surfaces of board 302 may be joined using techniques appropriate for the physical and chemical properties of the various layers and which are know in the art. Thus, for example and without limitation, surfaces 312 and 324, surfaces 314 and 332, and graphics layer 333 or surface 334 and surface 336 may be joined using an adhesive or resin layer, or joined directly by heating and fusing the layer materials. In one embodiment, a resin, such as an ethylene vinyl acetate resin, is extruded on one of the surfaces to be joined, and the resin is heated prior to compressing the surfaces together. Alternatively, a polyethylene layer may be used to join surfaces. In yet another embodiment, a layer may be joined to the adjoining layer by heating and extruded one layer material onto the adjoining layer surface. It is to be understood that the illustration or discussion of the application of an adhesive layer is optional for materials that can be forced to bond directly to one another.
FIG. 4 is a second embodiment of a board 402, which may be generally similar to boards 102 or 302, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of FIGS. 1, 2, 3A, 3B, and 4.
Core 310 of board 402 is a multi-layered foam core, including a center foam material 411, a top foam material 413 and a bottom foam material 415. Foam materials 413 and 415 are sometimes referred to herein as “backing foams.” Center foam material 411 is joined to top foam material 413 with an adhesive 401 and is joined to bottom foam material 415 with an adhesive 403. Top portion 320 is joined to top foam material 413 with an adhesive 405, and bottom portion 330 is joined to bottom foam material 415 with an adhesive 407. Alliteratively, for surfaces that may be fused directly, such as polyethylene, adhesive layers are optional.
Also shown in FIG. 4 is a layer 422 including adhesive 401, top foam material 413, and adhesive 405, a top layer 420 including top portion 320 and layer 422, a layer 432 including adhesive 403, bottom foam material 415 and adhesive 407, and a bottom layer 430 including bottom portion 330 and layer 432.
The following embodiment is illustrative of the structure of board 402, and is not meant to limit the scope of the present invention. In one embodiment, center foam material 411 is a foam with a density of from approximately 0.75 pounds per cubic foot to approximately 4 pounds per cubic foot. Center foam material 411 may be an expanded polyethylene, expanded polystyrene, polypropylene, or a polyethylene/expanded polystyrene blend. The thickness of foam material 411 (that is, distance between materials 413 and 415) may be from approximately 10 mm to approximately 125 mm.
Top foam material 413 and bottom foam material 415, may have the same or different materials or dimensions. The density of either one of materials 413 or 415 is from approximately 1 pound per cubic foot to approximately 10 pounds per cubic foot. The material of either one of materials 413 of 415 may be a polyethylene or a cross-linked polyethylene. The thickness of either one of materials 413 or 415 is from approximately 1 mm to approximately 5 mm.
In one embodiment, film 321 is a layer of polyethylene having a thickness of from approximately 0.01 mm to approximately 2 mm. Graphics layer 323 is formed by roller printing on film 321, where the graphics receiving side of the film first undergoes a coronal treatment to facilitate the adherence of ink on the film.
Fabric layer 331 is a non-woven material, which may be formed for example, formed from polyester fibers (one such material is NEXUS™, Precision Fabrics Group, Greensboro, N.C.). In one embodiment, fabric layer 331 is from 2 to 10 mils thick. Graphics layer 333 is a forward printed ink image. Clear layer 335 is layer of polyethylene, such as a low density polyethylene or a high density polyethylene, with a thickness of from approximately 0.01 mm to approximately 2 mm. For joining a layer to an expanded polystyrene material, an ethylene vinyl acetate resin may be used for adhesive 401, 403, 405 and 407. Ethylene vinyl acetate resin will bond to expanded polystyrene upon the application of heat and pressure.
FIG. 5 is a third embodiment of a board 502, which may be generally similar to boards 102, 302, or 402, except as further detailed below. Where possible, similar elements are identified with identical reference numerals in the depiction of the embodiments of FIGS. 1, 2, 3A, 3B, 4, and 5.

Sheet 1401 is first joined at an edge of surface 1503, and the platen 1510 and sheet manipulation unit 1520 are moved to feed sheet 1401 through adhesive activation unit 1530 and between surface 1503 and laminating roller 1540.
As shown in FIG. 16, material 1501 is then turned over, a sheet 1401 is positioned, with the adhesive layer of sheet 1501 facing surface 1505. and the steps of FIG. 15 are repeated to laminate sheet 1501 on surface 1505. In one embodiment, the laminated structure is board 402. In an alternative embodiment, the methods and equipment of FIGS. 15 and 16 are replaced with a press.
FIG. 7 is a flowchart 700 illustrating one method of manufacturing board 502. The method includes forming different parts of sports board 502, and then joining the in several laminating steps. Where possible, similar elements are identified with identical reference numerals in the depiction of the previous embodiments.
As shown in Block 601 of FIG. 7, top layer 320 is formed. In Block 701 top layer 320 is joined to one side of a backing foam (such as foam material 511). In Block 603 bottom printed layer 340 is formed. In Block 703 bottom printed layer is joined to the opposite side of the backing foam. In Block 705 a clear layer is applied over the printed bottom layer. In Block 707 the board is cut to size. The order of some of these steps may be rearranged in the manufacture of board 502.
One embodiment of flowchart 700 will now be discussed. This process is generally similar to the method described with regard to the flowchart of FIG. 6, except where explicitly stated. Where possible, similar elements are identified with identical reference numerals in the depiction of the previous embodiments. It is understood that this embodiment is one method of manufacturing sports board 502, and other steps, combinations of steps, or order of steps are within the scope of the present invention.
The process of Blocks 601 and 605 of FIG. 7 are described above. In one embodiment, Block 601 produces a roll 807 of printed layer 809, and Block 603 produces a roll 907 of printed layer 909. FIGS. 17A, 17B, and 17C are three consecutive schematics illustrating the process and manufacturing equipment to accept rolls 1001 of material 1003, which may be foam material 511, and rolls 807 and 907 and form a board 502.
FIG. 17A illustrates one embodiment of the processes of Blocks 701. Starting with roll 807 of top portion material, roll 907 of bottom printed layer material, and a roll 1001, which may include foam material 511. First, the material of roll 807 is joined to the material of roll 1001.
Foam material 1003 is unwound from roll 1001, passes through tensioning device 1010, through extrusion device 1020 where adhesive layer 1025 is placed on one side of material 1003, and through a first adhesive treatment device 1030. Roll 807 is unwound with the non-printed side 803 of printed layer 807 facing foam material 1003. Printed layer 807 passes through tensioning device 1110, and past adhesive activating unit 1130, where layer 1025 and layer 807 are heated, and through laminating rollers 1140.
FIG. 17B illustrates one embodiment of the processes of Blocks 703 and 705. The process of FIG. 17A continues from the position marked “A.” The bottom material is joined to the foam (Block 703), as the material passes through adhesive extrusion device 1040 where layer 1045 of adhesive is applied and passes through second adhesive treatment device 1050. Roll 907 is unwound with the non-printed side of printed layer 907 facing foam material 1003. Printed layer 907 passes through tensioning device 1110, and past adhesive activating unit 1230, where layer 1045 and layer 907 are heated, and through laminating rollers 1240.
A clear layer is applied to the bottom printed layer (Block 705) as the material passes through extrusion device 1250, where layer 1255 is applied to the printed side of the non-woven fabric, and through rollers 1260.
FIG. 17C illustrates one embodiment of the process of Block 707. The process of Block 17B continues from the position marked “B.” The material passes through die 1710 which stamps out the shape of board 502, which are accumulated as shown. In one embodiment, the stamping of the board occurs during the process illustrated in FIGS. 15 and 16, as the die cutting (Stamp) of the shape is completed just after the bottom is laminated to the core, and then the deck is laminated onto the top of the core.
