Abstract
A toy doll is articulated and removably attached to a toy scooter so that the doll's arms appear to steer the scooter and the doll's foot appears to tilt downward to push back against the ground and propel the scooter. Additionally, the animated toy doll and scooter assembly is controlled by a radio remote control unit itself shaped like a scooter and having a toy foot attached to it. The toy foot is slid forward or back to control the forward and reverse motion of the scooter and is turned to steer the scooter.
Description
BACKGROUND OF THE INVENTION
The invention relates generally to toys, and more particularly to an animated toy doll and scooter assembly.
U.S. Pat. No. 3,574,969 to Cleveland and Wilson discloses a toy doll and scooter assembly wherein a doll is attached to a scooter and uses a walking motion to push the scooter along. However, Clevland lacks realistic animation of the doll. The scooter tilts from side to side, as in a walking motion, rather than remaining substantially vertical as do real scooters. Additionally, Cleveland is only able to travel forward and cannot be turned like a real scooter.
SUMMARY OF THE INVENTION
A general object of the present invention is to provide a more realistically animated toy doll and scooter assembly.
In accordance with an illustrative embodiment of the invention, a toy doll is articulated and removably attached to a toy scooter so that the doll's arms appear to steer the scooter and the doll's foot appears to propel the scooter. Additionally, the animated toy doll and scooter assembly is controlled by a radio remote control unit itself shaped like a scooter and having a toy foot attached to it. The remote control unit provides a highly intuitive method for controlling the animated toy doll and scooter assembly. By sliding the attached foot forwards or backwards, the animated toy doll and scooter assembly is commanded to travel forwards or backwards. By turning the attached left or right the animated toy doll and scooter assembly is commanded to turn left or right.
More specifically, an animated toy doll and scooter assembly is provided which includes a toy scooter having front and rear large size main wheels and several smaller stabilizing wheels. The scooter has a pivotal front wheel for turning, and handlebars linked to the front wheel. A doll is mounted on the scooter with its arms secured to the handlebars. The scooter has a motor mounted thereon for actuating at least one of the wheels for forward movement. The doll has a leg and foot assembly linked to the motor for movement up and down, or tilting, and front to rear to simulate scooter actuation motion. In addition, a second motor may be provided, or a coupler from the first motor may be provided, to turn the front wheel of the scooter.
These objects as well as other objects, features and advantages of the invention will become more apparent to those skilled in the art from the following description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Disclosed herein is a detailed description of the best presently known modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention. The overall organization of the present detailed description is for the purpose of convenience only and is not intended to limit the present invention.
FIG. 1
shows an animated toy doll and scooter assembly
12
including a toy doll
14
positioned on a toy scooter
16
. Arms
18
are secured to scooter handlebars
20
. A foot
22
supports the doll on a floorboard
26
of the scooter. Another foot
24
is positioned on a foot movement actuating member
28
. Also shown are front
36
and rear
38
large size main wheels. The rear wheel
38
can be used to propel the scooter
16
while the front wheel
36
is used to steer the scooter
16
. A steering assembly
48
is made up of the handlebars
20
, a steering column housing
44
, a steering actuating assembly
46
and the front wheel
36
.
In one embodiment the animated toy doll and scooter assembly is controlled by a radio remote control unit
30
. The radio remote control unit
30
contains a radio transmitter as known in the art. The remote control unit
30
is shaped as a smaller version of the toy scooter
16
. The remote control unit can transmit radio signals through an antenna extending along the remote control unit
30
handlebars
34
. The remote control unit
30
can be two-thirds or less of the size of the toy scooter
16
so that it can be easily held by a child. Mounted on a sliding switch is a toy shoe
32
. By sliding the toy shoe forward and backward along a remote control floorboard
33
, a user can make the toy scooter
16
move forwards and backwards. Positioning the toy shoe to an intermediate position stops the scooter and moving the toy shoe further to the front or rear increases the forward or reverse speed of the toy scooter. By turning the foot
32
clockwise or counterclockwise, a user can similarly make the scooter handlebars
20
turn clockwise or counterclockwise, and turn a front wheel
36
, causing the forward moving scooter to turn right or left. Radio remote control units are known in the art, however, the remote control unit
30
of the present invention provides special advantages when included with the animated toy doll and scooter assembly of the present invention. The design of the remote control unit
30
makes its use in controlling the toy scooter
16
highly intuitive, allowing younger children to quickly comprehend how to use the remote control unit
30
to control the toy scooter
16
.
FIG. 2
shows the toy scooter
16
from a bottom perspective. Three small stabilizing wheels
40
are shown. The stabilizing wheels
40
can have diameters less than two-thirds the diameter of the main wheels
36
,
38
. The stabilizing wheels are mounted on opposite sides of the scooter. As illustrated in
FIG. 1
, the doll tends to move the center of gravity of the animated toy doll and scooter assembly
12
away from the center of the floorboard
26
and towards the foot movement actuating member
28
. It is therefore particularly important to have at least one stabilizing wheel positioned on the same side of the scooter as the foot movement actuating member
28
. Also shown is a battery compartment cover
42
for allowing insertion and removal of batteries. In one embodiment 6 AA batteries, providing approximately 9 V, can be used to power the animated toy doll and scooter assembly.
FIG. 3
shows a top view of the scooter with the top section and the steering assembly
48
removed from casing walls
49
to show the inner operating mechanisms. The scooter
16
is propelled by a drive motor
44
powered by the batteries or other power source. The motor
44
turns the rear wheel through a step-down gear train
50
. The gear train
50
transfers the relatively fast spinning of the motor to a relatively slow, but more powerful, spinning of the wheel
38
. Included in the gear train
50
is a clutch
52
for preventing the burning out of the motor
44
when the wheel
38
experiences an excess amount of resistance to spinning. The speed of the motor is controlled by sliding the toy foot
32
of the remote control
30
forward and backward. As the toy foot
32
is slid further forward, the motor
44
spins faster in the forward driving direction. As the toy foot
32
is slid further backward, the motor
44
spins faster in the reverse driving direction. The motor
44
stops spinning when the toy foot
32
is positioned and an intermediate position approximately between the furthest forward and furthest back sliding positions.
Driven by the same motor
44
is a foot-pedal actuation mechanism
54
. The foot-pedal actuation mechanism
54
gives the foot
24
and leg segments
58
,
60
of the doll
14
(see
FIG. 4
) a pedaling motion whereby the foot is tilted and moved from front to rear, simulating a driving engagement of the foot with the ground. The motor
44
actuates the pedaling mechanism
54
through a step-down gear train
56
. The gear trains
50
,
56
share some of the same gears. Thus, the foot
24
pedaling motion corresponds to the speed of the scooter
16
. As the scooter
16
goes faster, the foot
24
pedals faster, and as the scooter
16
goes slower, the foot
24
pedals slower. Alternatively, separate motors can be used to propel the scooter
16
and move the foot movement actuating member
28
.
The foot-pedal actuation mechanism
54
is described with reference to
FIGS. 3
,
5
and
7
-
10
. The foot-pedal actuation mechanism
54
includes a pedal drive cam
62
rotated by a shaft
64
which is rotated by the gear train
56
. A peg
66
extends outwardly from the cam
62
to engage a linear cam follower
68
. The follower
68
has a vertical slot
84
along which the peg
68
rides up and down. On the face of the follower
68
opposite the slot
84
is a horizontal slot
86
into which a shelf
88
extends from the casing wall
49
. The horizontal slot
86
and shelf
88
limit the follower to substantially horizontal motion. Pivotally connected to the follower
68
at a pivot point
70
is a foot-tilting follower
72
. Rigidly connected to the follower
72
is foot tilting shaft
74
having a foot movement actuating member
28
and a foot securing pin
76
attached at the opposite end. The pin
76
is used to help removably secure the foot
24
to the foot movement actuating member
28
. Extending from the follower
72
is a peg
78
which rides inside a groove
80
within a camming groove piece
82
.
The operation of the foot-pedal actuation mechanism
54
is now described with particular reference to
FIGS. 7-10
. The pedal drive cam
62
rotates about a fixed axis causing the peg
66
to ride up and down in the vertical slot
84
formed in the linear cam follower
68
. The follower
68
is constrained to substantially horizontal motion by the shelf
88
around which the horizontal slot
86
slides. Thus the rotation of the cam
62
leads to substantially linear horizontal motion of the follower
68
. As the follower
68
moves horizontally, the foot-tilting follower
72
moves forward and back and pivots relative to the follower
68
about the pivot point
70
. The peg
78
is driven around the groove
80
of the stationary camming groove piece
82
. The foot
24
, attached to the foot tilting shaft
74
, is thus tilted up and down and moved from front to rear, simulating a driving engagement of the foot with the ground. During forward motion the cam spins in the clockwise direction illustrated by arrows
90
, driving the peg
78
around the groove
80
in the clockwise direction illustrated by arrows
92
. During reverse motion the directions are also reversed.
FIG. 7
illustrates the foot-pedal actuation mechanism
54
with the foot
24
driven to its forward-most position by the cam
62
. At the same time, the foot is tilted downwards to a toe-down position by the peg
78
reaching the bottom-forward position in of groove
80
. This position simulates the foot
24
at the forward position with the toes down and ready to push back against the ground to drive the toy scooter
16
.
FIG. 8
illustrates the foot-pedal actuation mechanism
54
with the foot
24
driven to an intermediate position by the cam
62
with the peg
78
reaching the bottom-rear position of the groove
80
. This position simulates the foot
24
final position at which the toes have finished pushing back against the ground yet are still pointing down.
FIG. 9
illustrates the foot-pedal actuation mechanism
54
with the foot
24
driven to its rear-most position by the cam
62
. At the same time, the foot is returned to a raised, toe-up horizontal position by the peg
78
reaching the top-rear position in of groove
80
. This position simulates the foot
24
lifted up from engagement with the ground and ready to move forward.
FIG. 10
illustrates the foot-pedal actuation mechanism
54
with the foot
24
driven to an intermediate position by the cam
62
and with the peg
78
reaching the top-front position of the groove
80
. This position simulates the foot
24
returned to a forward position just before lowering the toes again in preparation for pushing back against the ground.
FIG. 5
diagrammatically shows a side view of the foot-pedal actuation mechanism
54
relative to the scooter
16
. The forward and back motion of the foot tilting shaft is illustrated within a slot
94
. Also illustrated is the motion of the peg
78
around the camming groove piece
82
. An optional spring
108
is shown attaching the follower
68
to a rearward fixed position. The spring is stretched as the foot
24
moves forward so that the foot will move faster during the backward motion than the forward motion giving the doll
14
an appearance of strongly pushing back against ground.
When the scooter
16
travels in the backward direction all directions illustrated
FIGS. 3
,
5
and
7
-
10
and described in the corresponding descriptions are reversed.
As illustrated in
FIG. 4
, the doll
14
is articulated with ankle joints
96
, knee joints
98
and hip joints
100
so that the foot
24
can be tilted down and lifted up and so that the entire leg can move forward and backward with the foot movement actuating member
28
.
The operation of the steering mechanism is now described with particular reference to
FIG. 6. A
steering motor
102
turns a drive train
104
comprising step down gears. The drive train
104
transfers spinning motion to a pinion
106
which then causes a rack
110
to turn a steering column
112
. The steering column
112
then causes the front wheel
36
and handlebars
20
to turn together. The step down gears
104
transfer the relatively fast spinning motion of the motor
102
to a relatively slow motion of the pinion
106
. The steering column
112
can be biased with a centering spring. In one embodiment, the front wheel
36
can be steered through a 74 degree range.
As shown in
FIG. 4
, the doll
14
is articulated with wrist joints
114
, elbow joints
116
, shoulder joints
118
and a waist joint
120
. When the doll
14
is placed on the scooter
16
, the foot
24
is removably secured to the floorboard
26
using two pegs
124
,
126
disposed to fit within two holes formed in the bottom of the foot
22
. Also, the peg
76
is fit within a hole formed in the bottom of the foot
24
. Hands
28
are then removably secured to the handlebars
20
as illustrate in FIG.
1
. The shoulder joints
118
are used to raise the hands to the proper level. The wrist joints
114
are especially designed to generally pivot within a plane approximately formed between the elbows and the handlebars. The elbow joints
16
also pivot within the same plane as the wrist joints
114
. Thus, as the handlebars
20
turn the jointed arms
18
appear to be steering the scooter
16
in a life-like manner.
Returning to
FIG. 3
, within an electronics area
128
are conventional radio receiving circuits for receiving commands from the remote control
30
. Also within the electronics area
128
are circuits for controlling the motors
44
,
102
. The 6 AA batteries are located at the bottom of the electronics area
128
.
In one embodiment, the scooter is less than two feet long, and in particular approximately one foot long measured from the furthest forward part of the wheel
36
to the furthest rearward part of the wheel
38
. The floorboard
26
can have a length of approximately 7.5 inches and a width of approximately 3.5 inches. The scooter can have a height of approximately 9 inches from the bottom of the wheels
36
,
38
to the top of the handlebars
20
. The height from the bottom of the wheels
36
,
38
to the top of the floorboard can be approximately 1.5 inches. The wheels
36
,
38
can have diameters of approximately 2.25 inches. The stabilizing wheels
40
can have diameters of approximately 0.5 inches.
As for the remote control unit
30
, the total length can be approximately 7.5 inches, and the height from the bottom of the wheels to the handlebars can be approximately 5 inches. The width can be approximately 2.75 inches.
The present invention is not limited to scooters. The invention can take the form of other types of vehicles as well, such as skateboards or motorcycles, by way of examples, but not of limitation. For example, it can take the form of vehicles having one, three, four or other numbers of wheels. Also, instead of using wheels, slides can be used as the main or stabilizing structures. Furthermore, different types of dolls can be used to ride the vehicle. Also, the invention is not limited to use with a particular type of controller. Any kind of controller can be used or else the animated toy doll and scooter assembly can have a memory and processor onboard, for example, to lead the animated toy doll and scooter assembly on a particular predetermined or random course. Accordingly, the invention is not limited to the precise embodiments described in detail hereinbefore.
