DETAILED DESCRIPTION OF THE INVENTION

(8) The above-described drawing figures illustrate the invention, a skateboard that can be converted into different forms for different users and for different styles of use.

(9) FIG. 1 is a top perspective view of a skateboard 10 according to one embodiment of the present invention. FIG. 2 is an exploded perspective view thereof. FIG. 3 is a close up exploded perspective view of a first end 12 of the skateboard 10, illustrating a mounting structure 50 of a scooter handlebar 40. FIG. 4 is a close up view of a second surface 18 of the first end 12 of the skateboard 10.

(10) As shown in FIGS. 1-3, the skateboard 10 includes a platform 14 having a first surface 16 and the second surface 18 that each extend to an outer perimeter 22. The platform 14 extends longitudinally from the first end 12 to a second end 24, the first end 12 and, in FIGS. 1-2, a second end 24 being separated by a central portion 26. The platform 14 may be any shape desired by the user, although it is typically a generally rectangular, oval, or a similarly useful shape. The platform may be made of any material suitable for supporting a rider, such as wood, plastic, etc.

(11) As shown in FIGS. 3-4, a first truck mounting structure 28a is adjacent the first end 12, and a second truck mounting structure 28b is adjacent the second end 24. The truck mounting structures 28a and 28b are typically mounting bolts, which are received by bolt holes 29, although other mounting structures devised by those skilled in the art may also be used.

(12) As shown in FIGS. 1-2 and 4, a first truck 32a, for mounting a first pair of wheels 34a, is mounted to the platform 14 via the first truck mounting structure 28a; and a second truck 32b, for mounting a second pair of wheels 34b, is mounted to the platform 14 via the second truck mounting structure 28b. The first and second truck mounting structures 28a and 28b are adapted so that the first and second trucks 32a and 32b may be mounted on the first and second truck mounting structures 28a and 28b, respectively, on either the first surface 16 or the second surface 18 of the platform 14. This is illustrated in FIGS. 5 and 6, and described in greater detail below. Importantly, only the first and second pairs of wheels 34a and 34b, positioned at the first and second end 12 and 24 of the platform 14, respectively, contact the ground surface while a user is riding the skateboard 10.

(13) As shown in FIGS. 1-3, the skateboard 10 may be used in conjunction with the scooter handlebar 40 so that the skateboard 10 may be used as a scooter. In this embodiment, the scooter handlebar 40 includes a vertical post 42 with a pair of handles 44 extending laterally from a top end 46 of the vertical post 42. A lower end 48 of the vertical post 42 includes a pair of depressible heads 66 and is engaged with the mounting structure 50. The mounting structure 50 includes, in this embodiment, a cylindrical securing mechanism 68 having a hollow top end 72 sized to receive the vertical post 42 and engage with the pair of depressible heads 66. The top end 72 may be pivotally mounted on a lower end 75, separated by a flange 73 extending outwardly from the top end 72.

(14) The mounting structure 50 may further comprise an externally threaded stump 52 that receives the securing mechanism 68, and a cap 74 that covers the securing mechanism 68 and threadedly engages with the stump 52. In this embodiment, the cap 74 engages the flange 73 of the securing mechanism 68. The externally threaded stump 52 extends from a platform engaging structure 54, which is a rigid plate that curves at the same degree as the perimeter 22 of the platform 14. Shown in FIGS. 2-4, The platform engaging structure 54 may further include a pair of laterally spaced protrusions 56 and a locking lip 62 that extends downwardly and is positioned between the protrusions 56. The pair of protrusions 56 are shaped to frictionally engage a pair of apertures 58 through corners of the platform 14. The platform 14 may include pairs of apertures 58, at the first end 12 and the second end 24, respectively; or a single pair may be included, or other arrangement of apertures that may be desired by one skilled in the art. The apertures 58 are useful for not only mounting different items onto the platform 14, they also provide a place to grab the platform 14 while the skateboard 10 is being ridden in a seated position. In construction, the locking lip 62 fits over the outer perimeter 22 of the first end 12 (or the second end 24, if desired), extending downwardly and angling so that it secures on the underside of the first surface 16 (or the second surface 18, depending on the current configuration), to lock the mounting structure 50 onto the platform 14.

(15) As shown in FIG. 4, the protrusions 56 each include a locking mechanism 64 for removably locking the protrusions 56 within the corresponding apertures 58, to prevent disengagement of the mounting structure 50 from the platform 14. In the embodiment of FIG. 4, the locking mechanism 64 includes a spring 76 and a pair of heads 78, the spring 76 being within the hollow protrusion, and the pair of heads 78 without, so that the heads 78 may be depressed to release the protrusion 56 from the platform 14. While one embodiment of the locking mechanism 64 is illustrated, those skilled in the art may devise alternative embodiments (such as a flange, clip, ring mechanism, etc.) which should also be considered within the scope of the present invention.

(16) The first and second surfaces 16 and 18 may include high frictional material such as grip tape, and may further include a padded tape that may be better for sitting on the platform 14 (i.e., such as when a child is using the board and sitting on it). The padded tape is typically installed over the central portion 26, where a child may often sit while riding the skateboard 10 from a seated position. A marking coating may also or alternatively be included over a portion of the skateboard 10 which may be used for marking on the skateboard 10 (e.g., with dry-erase markers, chalk, etc.). In one embodiment, both the platform 14 and the wheels 34a and 34b may be covered in a dry-erase marking coating, to allow a user to decorate the skateboard 10 as desired.

(17) FIG. 5 is a side elevational view of the skateboard 10 in a first configuration, where the first and second trucks 32a and 32b are mounted on the first surface 16 of the platform 14. FIG. 6 is a side elevational view of the skateboard 10 in a second configuration, where the first and second trucks 32a and 32b are mounted on the second surface 18 of the platform 14. As shown in FIGS. 5 and 6, the platform body is formed so that the platform 14 is laterally planar, and longitudinally bent in opposite directions at the first end 12 and second end 24, relative to the central portion 26 and current truck configuration.

(18) In the embodiment of FIGS. 5 and 6, the central portion 26 of the platform 14 is longitudinally bent to curve in an arc between the first and second truck mounting structures 28a and 28b. In the first configuration, shown in FIG. 5, this results in the central portion 26 being spaced a first distance D1 that is small, so that the central portion 26 is close to the ground. In the second configuration, shown in FIG. 6 (once the board has been flipped over), this results in the central portion 26 being spaced a second distance D2 that is larger than D1, so that the central portion 26 is further from the ground. This enables the user to modify the configuration of the skateboard 10 between two different modes of use by flipping the platform 14 of the skateboard 10 relative to the trucks 32a and 32b. In either case, the ends form

(19) In FIGS. 5 and 6, the skateboard 10 is illustrated without the scooter handlebar 40 of FIGS. 1-3, illustrating the easy customization of the skateboard 10 for different modes of use.

(20) The mounting structure 50 described above may also be used for mounting alternative accessories to the skateboard 10 aside from the scooter handles 44. For example, camera devices such as a GOPRO may be mounted onto the skateboard 10, or any desired object that may be attached via the mounting structure 50, such as a seat attachment, a wagon handle, a basket, etc. Those skilled in the art may devise a wide range of objects or structures that a user may want to removably attach to the skateboard, and any such object or structure should be considered within the scope of the present invention.
