ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a remote control running toy which is operated by a remote controller.
As shown in
FIG. 1
, the remote control running toy of the conventional type is generally provided with a suspended chassis
14
on which a car body mounts, a pair of right and left uprights
24
, each having a kingpin
22
for steerably supporting a pair of right and left front wheels
20
fitted at the front of the chassis
14
, a pair of right and left upright holders
26
connected through the right and left uprights
24
to the right and left front wheels
20
, and a pair of supporting shafts
28
for pivotably supporting the right and left upright holders
26
so as to allow the uprights
24
to move up and down in accordance with the displacement of the center of front wheels
20
upwardly and downwardly relative to the chassis
14
, wherein the right and left uprights
24
are coupled through one end of each steering rod
30
with a steering mechanism
32
. This steering mechanism
32
disposed on the chassis
14
is provided with a driving motor
38
for driving a disc-shaped cam
34
fixedly mounted on a shaft
36
of the motor
38
, the cam
34
being coupled with another end of each steering rod
30
, thereby causing the steering rods
30
to move in lateral directions perpendicular to a longitudinal direction of the chassis
14
as the cam
34
is rotated by the motor
38
. As the result, the running direction of the front wheels
20
is controlled by the steering mechanism
32
.
However, the remote control running toy of the conventional type has a drawback that when the front wheels are happened to be collided against an obstacle during the driving of the running toy, the impact force produced by the collision is transmitted through the uprights to the steering rods, causing damages to the steering rods or the steering mechanism.
SUMMARY OF THE INVENTION
The present invention has been done in view of solving the drawback, and therefore, an object of the present invention is to provide a remote control running toy capable of avoiding the damages from being damaged, even if a strong shock acts onto the front wheels, thereby improving the reliability of the running toy.
To achieve the above objects, the present invention provides a remote control running toy comprising: a suspended chassis on which a car body mounts; a rear-wheel driving mechanism for running the chassis by driving a pair of right and left rear wheels fitted respectively at the right and left rear sides of the chassis; a pair of uprights, each having a kingpin for steerably supporting a pair of right and left front wheels fitted respectively at the right and left front sides of the chassis; and a steering mechanism coupled through steering rods with the uprights; wherein the running toy is provided with a shock absorber for absorbing a shock transmitted through the uprights to the steering rods
Preferably, the shock-absorber is a coil-shaped spring member formed by winding up a part of the steering rods made of a metal wire in a coil-like form.
