Skateboard with steering wheel

A skateboard with steering wheel for steering control, the body of which having two opposite holes at the front biased inward from a transverse line through 4-5 angle for fastening two front wheels by two wheel holders, and two ring-shaped members for fastening two rear wheels by two wheel hubs and a wheel axle. A steel tube is fastened in a tubular seat on the body of the skateboard and rotated by a steering wheel two turn the front wheels by a link for steering control.

BACKGROUND OF THE INVENTION 
The present invention relates to skateboards and relates more particularly 
to a skateboard with a steering wheel for steering control which has means 
to prevent an user from jamming the fingers or the toes. 
Conventionally, a skateboard is simply made from a flat board mounted on 
rollers for riding. This simple structure of skateboard is not easy to 
control its steering direction. Recently, several skateboard manufacturers 
have tried to fasten a steering wheel in a skateboard for easy steering 
control. However, these structures are still not satisfactory in use 
because there are gaps left between the board and the two front wheels 
thereof. During riding, a player tends to jam one's toes or fingers in the 
gaps. 
SUMMARY OF THE INVENTION 
The present invention has been accomplished to eliminate the aforesaid 
problems. It is therefore an object of the present invention to provide a 
skateboard which has a steering wheel for easy steering control. It is 
another object of the present invention to provide a skateboard which is 
safe in use. 
According to the present invention, there is provided a skateboard with 
steering wheel which is generally comprised of a body having two front 
wheels secured in place by two wheel holders, two rear wheels secured in 
place by a wheel axle and two wheel hubs, and a steering wheel connected 
to said front wheels by a link and a steel tube. Rotating the steering 
wheel causes the link to turn the front wheels from one direction to 
another. By means of the arrangement of the wheel holders, turning the 
front wheels does not produce gaps between the body and the front wheels. 
Therefore, jamming accident is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIGS. 1 and 2, a skateboard as constructed in accordance with 
the present invention is generally comprised of a body 1, a steering wheel 
2, a bellows pipe 3, a steel tube 4, two wheel holders 5, 6, two front 
wheels 7, 8, two rear wheels 9, 10, and a wheel axle 20. 
The body 1 has a first pair of holes 11, 12 bilaterally disposed at one end 
in vertical direction for fastening the two front wheels 7, 8 by the two 
wheel holders 5, 6, a second pair of holes 13, 14 and a pair of 
ring-shaped members 15, 16 bilaterally disposed at an opposite end in 
horizontal direction for fastening the two rear wheels 9, 10 by the wheel 
axle 20, a tubular seat 17 vertically disposed at the middle in line with 
said first pair of holes 11, 12 for fastening the steering wheel 2 by the 
steel tube 4 and the bellows pipe 3, which tubular seat 17 has a hole 171 
adjacent to the bottom edge thereof (see FIG. 6). 
The steering wheel 2 has a through-hole 21 at the bottom for fastening the 
steel tube 4. The steel tube 4 has two pivot holes 41, 42 at two opposite 
ends. Once the steel tube 4 is inserted into the bellows pipe 3, it is 
secured to the steering wheel 2 by a screw 22, which is inserted through 
the through-hole 21 and the pivot hole 41, and a locknut 23. The opposite 
end of the steel tube 4 is inserted into the tubular seat 17 and secured 
in place by a screw 45 and a locknut 46. While fastening the screw 45 and 
the locknut 46, a link 44 is simultaneously secured to the tubular seat 17 
beneath the body 1. The link 44 has an arched hole 443 at the middle 
through which the screw 45 is inserted. Further, before inserting the 
steel tube 4 into the tubular seat 17, a metal plate 43, is fastened 
inside the tubular seat 4. The metal plate 43 has three toothed projection 
431, 432, 433 formed through the process of punching and is provided to 
prohibit the steel tube 4 from rotating the tubular seat 17 when the steel 
tube 4 is rotated by the steering wheel 2 (see FIG. 3). 
The two wheel holders 5, 6 each has a hole 51 or 61 fastened to the hole 11 
or 12 on the body 1 by a bolt 52 or 62 and a locknut 53 or 63, a recessed 
hole 55 or 65 at a suitable location into which either end 442 or 441 of 
the link 44 is engaged, and an axle 54 or 64 for holding either front 
wheel 7 or 8. The axle 54 or 64 of either wheel holder 5 or 6 has an outer 
thread 541 or 641 engaged with the inner thread 561 or 661 on a locknut 56 
or 66 to retain the front wheel 7 or 8 in place. The two holes 11, 12 on 
the body 1 are respectively biased inward from a transverse line through 
4.degree. to 5.degree. angle (see the angle .alpha. in FIG. 7). Therefore, 
the two wheel holders 5, 6 are slightly tilted inward after mounting. This 
special design prohibits the front wheels 7, 9 from being caused to tilt 
outward. 
The wheel axle 20 has two outer threads 201, 202 at two opposite ends. When 
two wheel hubs 203, 204 are respectively mounted on the two ring-shaped 
members 15, 16, the wheel axle 20 is inserted through the two center holes 
91, 101 of the two rear wheels 9, 10, the center holes 2031, 2041 on the 
two wheel hubs 203, 204, the two ring-shaped members 15, 16 and the second 
pair of holes 13, 14 on the body 1 with the two outer threads 201, 202 
thereof respectively engaged into the inner threads 2051 on two locknuts 
205, 206. 
Referring to FIGS. 4 and 5, during skating, both hands are held on the 
steering wheel 2 with one leg stepped on the body 1 and the other leg 
pushed against the ground in reverse direction to move the skateboard 
forward. By rotating the steering wheel 2, the moving direction of the 
skateboard is controlled. While turning the front wheels 7, 8 from one 
direction to another, no gaps will be produced between the front wheels 7, 
8 and the body 1. Therefore, a player will not jam one's fingers or toes 
in the front wheels during skating.
