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.
