invention, with reference to the accompanying drawings, in which: Figure 1 is a schematic side view of the preferred embodiment of a skateboard according to the present invention; l Figure 2 is a top planar view of the preferred embodiment; Figure 3 is a schematic side view of the preferred embodiment, illustrating how a rider stands on the skateboard in order to move the same in a forward direction; Figure 4 is a top planar view of the preferred embodiment, illustrating how the rider stands on the skateboard in order to move the same in the forward direction; Figure 5 is a schematic side view of the preferred embodiment, illustrating how the skateboard is tilted upward in order to turn the same to the left; Figure 6 is a top planer view of the preferred embodiment, illustrating how the rider stands on the skateboard in order to turn the same to the left; Figure 7 is a schematic side view of the preferred embodiment, illustrating how the skateboard is tilted upward in order to turn the same to the right; and Figure 8 is a top planer view of the preferred embodiment, illustrating how the rider stands on the skateboard in order to turn the same to the right.
Referring to Figures 1 to 4, the preferred embodiment of a skateboard according to the present invention is shown to include a board member 10, a front roller 31, a first axle 21, a rear roller 32, a second axle22, a pair ofleft and right intermediate rollers 33,34, a third axle 23, first and second transmission units 50, a power driving unit 40, and a control unit 60.
As illustrated, the board member 10 has opposite top and bottom surfaces 11,12, and front and rear ends 13,14. The bottom surface 12 of the board member 10 is provided with first, second and third brackets 31", 32", 33". The secondbracket32"is rotatable about a vertical axis relative to the board member 10.
IO The front roller 31 is mounted rotatably on the first bracket 31" through the first axle 21, which extends through the first bracket 31", and is disposed adjacent to the front end 13 of the board member 10.
The rear roller 32 is mounted rotatably on the second bracket 32" through the second axle 22, which extends through the second bracket 32", and is disposed adjacent to the rear end 14 of the board member 10. The rear roller 32 has a diameter less than that of the front roller 31.
The left and right intermediate rollers 33,34 are mounted on the third bracket33" through the third axle 23, which extends through the third brackets 33", and are disposed between the front and rear rollers 31,32.
Each of the left and right intermediate rollers 33,34 has a diameter the same as that of the front roller 31.
The first and second transmission units 50 are connected respectively to the left and right intermediate rollers 33,34.
The driving unit 40 is connected to the first and second transmission units 50. Preferably, a power source 43, such as a battery, is electrically connected to the driving unit 40.
The control unit 60 is mounted on the top surface ll of the board member lo, and is electrically connected to the driving unit 40. The control unit 60 is operable among a first mode, in which the driving unit 40 is activated to drive the left and right intermediate rollers 33,34 through the first and second transmission units 50, a second mode, in which the driving unit 40 is deactivated, a third mode, in which the driving unit 40 is activated to drive one of the left and right intermediate rollers 33,34 through the first transmission unit 50, and a fourth mode, in which the driving unit 40 is activated to drive the other one of the left and right intermediate rollers 33,34 through the second transmission unit 50.
In this preferred embodiment, the driving unit 40 includes first and second driving motors 41,42 that are disposed adjacent to the left and right intermediate rollers 33,34, respectively, and that have first and second output shafts 411,421, respectively. A rotation-controlling switch 70 is mounted on the top surface ll of the board member lO, and is electrically connected to the driving unit 40 so as to control rotating direction of the first and second output shafts 411,421. Each of the first and second transmission units 50 has a driving gear 51(52) fixed coaxially to a respective one of the first and second output shafts411, 421, end a driven gear53 (54) co-axially fixed to a respective one of the left and right intermediate rollers 33,34, and meshed with the driving gear 51 (52).
IO The control unit 60 preferably includes a first switch 61, a second switch 62 and a third switch 63.
