FIELD OF THE INVENTION
The present invention relates to a toy car built up
from a plurality of flat parts, and more particularly
to a built-up toy car with rotatable wheels . A front
and a rear axle part of the built-up toy car are provided
at upper and lower edges at positions engaging with
axle holes provided at lower front end and lower rear
end of the car, respectively, with two pairs of upper
and lower notches of a predetermined depth to form
thereat a reduced width slightly smaller than the axle
holes, so that the front and the rear axle parts are
rotatable in the axle holes relative to the body of
the toy car.
BACKGROUND OF THE INVENTION
A conventional toy car built up from a plurality of
flat parts usually includes a body, and a front and
a rear wheel assembly connected to lower front and lower
rear ends, respectively, of the body. The front and
the rear wheel assemblies both include a flat axle part
having two flat wheel parts connected to two ends thereof .
The axle parts are engaged at an upper edge with slits
provided at the lower front and the lower rear ends
of the body and thereby connect the wheel assemblies
to the body. The wheel assemblies connected to the body
in this manner are not rotatable relative to the body.
Thus, the conventional built-up toy car is only a toy
suitable for seeing statically and is less interesting
for playing.
It is therefore tried by the inventor to develop a
built-up toy car with rotatable wheels to eliminate
the drawback of the conventional built-up toy car.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide
a built-up toy car with rotatable wheels, so that the
wheels rotate to move the built-up toy car forward on
a plane when a player pushes the toy car.
To achieve the above and other objects, the built-up
toy car of the present invention mainly includes a body
assembled from a plurality of flat parts, and a
front-wheel assembly and a rear-wheel assembly
connected to a lower front and a lower rear end,
respectively, of the body. Both the front-wheel
assembly and the rear-wheel assembly include a flat
axle part supported in two open-bottomed axle holes
provided at the lower front end and the lower rear end,
respectively, of the body, and two flat wheel parts
connected to two ends of each axle part. Each of the
axle parts is provided at upper and lower edges at
positions engaging with the axle holes with two pairs
of upper and lower notches of a predetermined depth
to form thereat a reduced width slightly smaller than
an internal dimension of the axle holes, so that the
axle parts are rotatabie in the axle holes and thereby
bring the front-wheel and the rear-wheel assemblies
to rotate relative to the body and move the toy car
forward on a plane when a player pushes the toy car.
BRIEF DESCRIPTION OF THE DRAWINGS
The structure and the technical means adopted by the
present invention to achieve the above and other objects
can be best understood by referring to the following
detailed description of the preferred embodiments and
the accompanying drawings, wherein
Fig. 1 is an assembled perspective view of a built-up
toy car with rotatable wheels according to an embodiment
of the present invention; Fig. 2 is an exploded perspective view of Fig. 1; and Fig. 3 is a fragmentary, enlarged and partially
sectioned side view of the toy car of Fig. 1 showing
the manner in which the wheel assembly thereof rotates.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to Figs. 1 and 2 that are assembled and
exploded perspective views, respectively, of a built-up
toy car with rotatable wheels according to an embodiment
of the present invention. As shown, the built-up toy
car includes a body 10 assembled from a plurality of
flat parts and has a front-wheel assembly 11 and a
rear-wheel assembly 12 respectively connected to a
front and a rear portion thereof.
Both the front-wheel assembly 11 and the rear-wheel
assembly 12 include a flat axle part 16 and two flat
wheel parts 17 separately connected to two ends of the
axle part 16.
Each of the axle parts 16 is provided at upper and lower
edges at positions intended for engaging with the body
10 with two pairs of upper and lower notches 161 having
a predetermined depth, so that a width of each axle
part 16 at the positions having the notches 161 is
reduced.
Please refer to Fig. 3. Both a lower front end and a
lower rear end of the body 10 are provided at positions
for engaging with the axle parts 16 with two
open-bottomed axle holes 18. The front-wheel and the
rear- wheel assemblies 11, 12 are connected to the lower
front and the lower rear ends, respectively, of the
body 10 by engaging the two pairs of notches 161 of
their respective axle parts 16 with corresponding
open-bottomed axle holes 18. By making the reduced
width of each axle part 16 at the two pairs of upper
and lower notches 161 slightly smaller than an internal
dimension of each axle hole 18, the axle parts 16 are
rotatable in the axle holes 18 relative to the body
10.
Please refer to Fig. 2. In the illustrated embodiment
of the present invention, the axle holes 18 are round
in shape. Portions of the body 10 at two sides of a
bottom opening defined by each open-bottomed axle hole
18 extend toward each other to form two projections
181. The projections 181, due to their dimensions,
provide a certain extent of flexibility that enables
the axle parts 16 of the front-wheel and the rear- wheel
assemblies 11, 12 to rotatably mount in the axle holes
18 without easily separating therefrom.
Please refer to Figs. 1 and 2 again. Each axle part
16 of the front-wheel and the rear- wheel assemblies
11, 12 is provided at outer sides of the two pairs of
upper and lower notches 161 with two first wheel slits
162, and each of the wheel parts 17 is provided at a
predetermined position with a second wheel slit 171.
By engaging the second wheel slits 171 with the first
wheel slits 161, the wheel parts 17 are connected to
the axle parts 16.
With the above arrangements, a player may push the
built-up toy car of the present invention forward on
a plane with the front-wheel and the rear- wheel
assemblies 11, 12 rotating relative to the body 10.
The present invention has been described with a
preferred embodiment thereof and it is understood that
many changes and modifications in the described
embodiment can be carried out without departing from
the scope and the spirit of the invention that is intended
to be limited only by the appended claims.
