DETAILED DESCRIPTION

[0022] Unless defined otherwise, all terms of art, notations and other technical terms or terminology used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. All patents, applications, published applications and other publications referred to herein are incorporated by reference in their entirety. If a definition set forth in this section is contrary to or otherwise inconsistent with a definition set forth in the patents, applications, published applications, and other publications that are herein incorporated by reference, the definition set forth in this section prevails over the definition that is incorporated herein by reference.

[0023] Unless otherwise indicated or the context suggests otherwise, as used herein, a or an means at least one or one or more.

[0024] Furthermore, unless otherwise stated, any specific dimensions mentioned in this description are merely representative of an exemplary implementation of a device embodying aspects of the invention and are not intended to be limiting.

[0025] The present application provides an oversized wheeled board which combines a highly soft and flexible deck with wheels. Most skateboards, even larger ones, have relatively rigid decks made of materials such as bamboo and plyboard. The decks of the wheeled boards described herein are formed of layers of flexible materials adhered together to provide a highly flexible laminated construction. The flexible materials may be carbon fiber, fiberglass, foam or urethane, or other fiber-reinforced polymers. The flexible laminated construction of the deck provides added flexibility which provides certain advantages for the street surfer. Riders understand immediately that this board is by far the smoothest, most flexible, and enjoyable; the Rolls Royce of boards.

[0026] FIG. 1 is a front view of a user holding a wheeled board 20 of the present application so as to show the underside thereof. The board 20 includes an oversized deck 22 with a pair of trucks 24 mounted on the underside that support a plurality of wheels 26. As with conventional skateboards, there are preferably four wheels 26 and two trucks 24 as shown, though more wheels per truck may also be utilized.

[0027] The deck 22 has a height H of at least 4 feet in length, such as between about 48-60 inches, and a maximum width W of between about 15-20 inches. In a preferred embodiment, the height H is about 55 inches, and the maximum width W is about 17 inches. The deck 22 has generally straight end edges 30, four rounded corners 32, and gently convex side edges 34. The maximum width W is located approximately midway between the two end edges 30, and the widths of the end edges 30 is thus less than the maximum width W. Preferably, the end edges 30 have a smaller width of between about 9-12 inches, more preferably about 10 inches. Although these dimensions are preferred, the deck 22 may be shaped more like an oval, with more tapered ends, or have wider end edges 30 so as to be more rectangular.

[0028] FIG. 2A is a perspective exploded view of upper components of the wheeled board 20. A grip material layer 40 may be provided on the upper surface of the deck 22. Preferably the grip material layer 40 has a sandpaper like quality on its upper face and adhesive on its lower face, and is sized to cover the entire deck 22. A pair of reinforcing plates 42 fit within complementary recesses 44 formed in the upper surface of the deck 22. The plates 42 desirably have a thickness that is equal to or less than a depth of the recesses 44 so as to remain flush with or below the top surface of the deck 22. A plurality of fasteners 46, such as the four bolts shown, extend downward through the reinforcing plates 42 and attached to complementary mounting structure to hold the trucks 24 in place, as will be described below. The fasteners 46 may be hidden by the grip material layer 40 or pass through holes therein as shown. Preferably, the reinforcing plates 42 have countersunk holes so that heads of the fasteners 46 are flush with or below the top surface of the plates.

[0029] FIG. 2B is a perspective exploded view of lower components of the wheeled board 20 illustrating each of the trucks 24 having a mounting plate 50 thereon spaced below a riser plate 52. Both of mounting plates 50 and the riser plates 52 have aligned holes through which the fasteners 46 that extend down through the deck 22 pass. Complementary mounting structure such as locking nuts 54, as shown, secure to the fasteners 46 to hold the assembly in place, and the trucks 24 on the underside of the deck 22.

[0030] FIG. 3 is a side elevation view, partially cutaway, of the wheeled board 20 showing a thickness T of the deck 22 as well as a thickness t of one of the riser plates 52. In a preferred embodiment, the deck thickness T is between about -1 inches, and more preferably is closer to 1 inch. The riser plates 52 have a thickness t of between about -1 inches.

[0031] The riser plates 52 are preferably elastomeric (e.g., rubber) so that they act as shock absorbers between the mounting plates 50 and the underside of the deck 22 and enhance the overall flexibility of the board 20. This enables carving and other such maneuvers as done when ocean surfing, unlike conventional skateboards that lack stability and are too rigid. The riser plates 152 may also made of a lightweight metal such as aluminum.

[0032] The trucks 24 are desirably oversized which will allow the rider to make tighter turns without experiencing wheel bite. Stiffer trucks can compensate a little but the presence of the riser plate 52 keeps the wheels from contacting the underside of the deck 22.

[0033] FIG. 4 is a partial perspective view of a deck of the wheeled board 20 showing layers cut away to illustrate preferred constructional details. Preferably, the majority of the thickness of the deck 22 comes from a middle layer 60 of relatively soft material such as foam or urethane. An upper outer layer 62 and a lower outer layer 64 are sandwiched around the middle layer 60 with intermediate layers 66 of epoxy or other adhesive therebetween. The upper and lower outer layers 62 may be formed of a variety of firmer materials, such as various fiberglass, polyester, or other such easily molded products.

[0034] FIG. 5 is a perspective exploded view of lower components of an alternative wheeled board 120 of the present application. The board 120 includes an oversized deck 122 with a pair of trucks 124 mounted on the underside that support a plurality of wheels 126. As with conventional skateboards, there are preferably four wheels 126 and two trucks 124 as shown, though more wheels per truck may also be utilized.

[0035] The trucks 124 each having a flat mounting plate 150 thereon spaced below an elastomeric riser plate 152, with aligned holes through which fasteners 146 that extend down through the deck 122 pass. Complementary mounting structure such as locking nuts 154, as shown, secure to the fasteners 146 to hold the assembly in place, and the trucks 124 on the underside of the deck 122.

[0036] FIG. 6 is a side elevation view, partially cutaway, of the wheeled board 120 showing a thickness T of the deck 122 as well as a thickness t of one of the riser plates 152. In a preferred embodiment, the deck thickness T is between about -1 inches, and more preferably is closer to 1 inch. The riser plates 152 have a thickness t of between about 25-35 mm (1-1.5 inches). In addition, each riser plate 152 has a length of between about 75-85 mm and a width of between about 55-65 mm, and are generally sized about the same as the adjacent mounting plate 150. The riser plates 152 are relatively thicker than traditional risers and are preferably elastomeric (e.g., rubber) so that they act as shock absorbers between the mounting plates 150 and the underside of the deck 122 and enhance the overall flexibility of the board 120. This enables carving and other such maneuvers as done when ocean surfing, unlike conventional skateboards that lack stability and are too rigid. The riser plates 152 may also made of a lightweight metal such as aluminum.

[0037] The trucks 124 are desirably oversized, which will allow the rider to make tighter turns without experiencing wheel bite. Stiffer trucks can compensate a little but the presence of the riser plate 152 keeps the wheels from contacting the underside of the deck 122. The trucks each have a wheel axle of between about 200-210 mm in length. In the exemplary embodiment, there are two wheels mounted on the wheel axle of each of the trucks, and each wheel has a width of between about 65-75 mm and a diameter of between about 50-60 mm.

[0038] FIG. 7 is a partial perspective view of a deck of the wheeled board 120 showing layers cut away to illustrate preferred constructional details. Preferably, a plurality of middle layers 160 of flexible material are sandwiched together and adhered with epoxy or other adhesive. The plurality of middle layers 160 may be fiberglass or polyester. Upper and lower outer layers 162 may be formed of a variety of firmer materials, such as carbon fiber. A central layer 164 of a polymer is included, and may be a relatively soft material such as foam or urethane. In a preferred embodiment, there are at least four middle layers 160, and a total of at least nine layers overall. Also, all of the layers except the middle layer 164 are desirably about the same thickness, with the middle layer being thinner. For example, there may be eight layers each contributing about 12.5% of the total thickness, with a very thin middle layer 164.
