DETAILED DESCRIPTION AND BEST MODE OF THE INVENTION




Referring to

FIG. 1

, an interactive doll constructed according to the present invention is indicated generally at


10


, and preferably resembles a reduced-scale human figure with very exaggerated proportions. Doll


10


also may be male, female, or androgynous, or may be any one of a variety of alternative forms which may be appealing to children, including but not limited to animals, fantasy figures, or animated objects. Doll


10


may be of any appropriate size, but preferably is constructed such that a small child may easily carry and manipulate doll


10


.




Doll


10


may be constructed of any suitable material. For example, doll


10


shown in

FIGS. 1 and 2

is constructed of moldable plastic. The moldable plastic may be colored and shaped such that the doll has skin and features that resemble a human's skin and features. Alternatively, any other suitable material may be used to construct doll


10


. Doll


10


may also be painted, or otherwise decorated, to increase the doll's appeal to children.




Doll


10


may include a head


12


that preferably includes typical facial features such as a mouth


14


, a nose


16


, hair


18


, and an eye assembly


20


that includes eyes


22


and eyelids


24


. The features or similar features may be painted on doll


10


or may be otherwise constructed to resemble the appropriate features. For example, hair


18


, may be constructed of suitable stylable material such that hair


18


may be styled by a child. As depicted, hair


18


is long straight hair. However, hair


18


may be of any color, length, or texture. Additional facial features, depending on the form of doll


10


, may also be included on head


12


.




Doll


10


also may include a body or torso


25


, a neck


26


, and a base


28


. Alternatively, head


12


may be connected directly to body


25


, without any neck, or base


28


may be connected directly to head


12


, with or without some type of simulated body incorporated within base


28


. In the depicted embodiment, base


28


is shaped to resemble feet, however alternative configurations are within the scope of the invention.




As shown in

FIG. 1

, head


12


and base


28


, preferably in the shape of feet, are enlarged. Body


25


of doll


10


is out of proportion to the size of either head


12


or base


28


. The exaggeration of head


12


and base or feet


28


may make doll


10


more aesthetically appealing to a child or other consumer group.




In the preferred embodiment, the size of head


12


and feet


28


has functional qualities. In particular, the exaggerated features contain components for motion, as shown in FIG.


2


. For example, head


12


may be configured to hold a motor assembly


30


, preferably including head motor


32


and an eye motor


34


.




Similarly, feet


28


are constructed to hold a battery assembly


36


(also referred to as a power assembly) or other power source. A set of wires or other conductive pathway


38


in body


25


couples battery assembly


36


in feet


28


to motor assembly


30


in head


12


.




Doll


10


may be placed on a surface, such as a table, so that doll


10


remains in an upright standing orientation. Feet


28


stabilize doll


10


and support head


12


and body


25


. The exaggerated feet


28


, including battery assembly


36


, effectively act as a counterweight to head


12


and body


25


.




Referring back to

FIG. 1

, one animated feature of doll


10


is controlled rotational motion of head


12


, as indicated by arrow


100


. By controlling the motion of head


12


, doll


10


takes on a more life-like appearance. Head


12


is moveable about a vertical or upright axis


102


that extends lengthwise through doll


10


. Head


12


is moveable about axis


102


between at least two positions. For example, head


12


in

FIG. 1

is moveable between three predetermined positions, including a right-facing position A, a center position or intermediate position B, and a left-facing position C.




Turning now to

FIG. 3

, the electro-mechanical operation of head


12


may be more readily understood. As described above, head


12


moves relative to body


25


. Head motor


32


drives a drive gear assembly, symbolically illustrated in

FIG. 3

, which in turn drives toothed gear


46


. Gear


46


engages head position assembly


48


, which identifies the position of head


12


relative to body


25


.




Rotating gear


46


rotates head


12


relative to body


25


as gear


46


is driven around head position assembly


48


. As head


12


rotates relative to body


25


, gear


46


rotates about head position assembly


48


. Head position assembly


48


remains in a substantially stationary position relative to body


25


.




Head position assembly


48


is configured to contact a position monitoring structure on head


12


. As shown, the position monitoring structure in the depicted embodiment includes limit switches


50


,


52


and


54


. Limit switches


50


,


52


, and


54


are anchored to head


12


such that their position relative to the body is effected by rotation of head


12


.




The rotation of head


12


relative to body


25


is demonstrated in

FIG. 4

, in which head


12


is schematically illustrated and is shown with a dashed line.

FIG. 4

illustrates symbolically from an overhead perspective each of the three positions, shown in FIG.


1


. The three exemplary positions include right-facing position A, forward-facing position B, and left-facing position C. Body


25


is symbolically illustrated as a rectangular box with dashed lines, and feet


28


are shown with dashed lines as well. Head motor


32


drives head


12


about axis


102


relative to body


25


and feet


28


.




In

FIG. 4

, each position of head


12


relative to body


25


is identified by a different line quality. For example, right-facing position A, is illustrated with a solid line. Moreover, nose


16


is illustrated as facing the corresponding direction. Forward-facing position B, is represented by a dash dot line with the outline of nose


16


facing the forward direction. Likewise, left-facing position C, is shown in a dash double dot line with a corresponding outline of nose


16


as it would appear in this position. Although not shown, additional or alternative positions for head


12


are contemplated.




Head


12


is movable between each of positions A, B, and C. Hence, if head


12


starts in position A it may move to position B or to position C through position B. Similarly if head


12


starts in position C, it may move to position B or to position A through position B. Alternatively, if head


12


is in position B, then it may move to either position A or position C.




All of the above movements may be controlled by a microprocessor, shown in

FIG. 5

at


56


. Each limit switch provides an independent signal to processor


56


, relaying the position of head


12


, as head position assembly


48


impacts each limit switch


50


,


52


, or


54


. For example, when head


12


is in a right-facing position A, then head position assembly


48


contacts limit switch


50


. Alternatively, when head


12


is rotated from position A to forward-facing position B, head position assembly


48


contacts limit switch


52


. Similarly, when head


12


further rotates from position B to left-facing position C, head position assembly


48


contacts limit switch


54


.




Processor


56


may also direct head motor


32


to drive head


12


to a different position forming a feedback loop. This feedback loop allows processor


56


to identify and position head


12


in particular predetermined positions, such as right-facing position A, forward-facing position B, or left-facing position C. Moreover, processor


56


, as a result of the head position information, may direct additional responses, such as speech or other animation.




As described above, head position assembly


48


is designed to contact each limit switch when head


12


is in each of the predetermined head positions. The details of head position assembly


48


are seen best in FIG.


3


. As shown in

FIG. 3

, head position assembly


48


includes a lower toothed wafer


58


, a yielding biasing structure


60


and an upper wafer


62


. Gear


46


, which rotates with head


12


when driven by head motor


32


, is configured to engage and rotate about lowertoothed wafer


58


.




Upper wafer


62


is axially aligned with lower wafer


58


such that when head


12


is motor driven or at rest, lower wafer


58


and upper wafer


62


are parallel. Lower wafer


58


and upper wafer


62


are releasably coupled together. For example, as shown in

FIG. 3

, lower wafer


58


has a rim


64


, which fits into a receiver portion


66


on upper wafer


62


. Moreover, lower wafer


58


has an extended lobe


68


, which extends outward from the body of lower wafer


58


. When head position assembly


48


is in an operational position, which includes when head position assembly


48


is at rest or driven by head motor


32


, lobe


68


of lower wafer


58


is aligned and parallel with a substantially matching extension


70


on upper wafer


62


.




For example, as shown in the overhead view in

FIG. 5

, lobe


68


on lower wafer


58


is directly below extension


70


of upper wafer


62


. During motor operation, lower wafer


58


and upper wafer


62


remain in the position shown in

FIG. 5

where lobe


68


and extension


70


extend in a forward-facing direction relative to body


25


, akin to position B in FIG.


4


.




Returning attention again to

FIG. 3

, lobe


68


of lower wafer


58


has an upward projection


72


. Upper wafer


62


has a similar projection


74


on extension


70


. Upward projection


72


lies adjacent to downward projection


74


when head position assembly


48


is motor driven or at rest. When upward projection


72


and downward projection


74


are adjacent, upper wafer


62


and lower wafer


52


are aligned and parallel with identical orientations relative to body


25


. Lower wafer


58


also has a contact surface


76


, which is configured to contact the limit switches


50


,


52


, and


54


as head


12


moves between the predetermined positions.




Interposed between lower wafer


58


and upper wafer


62


is yielding biasing structure


60


. Yielding biasing structure


60


, as shown in

FIG. 3

, may be a spring or other suitable structure that coils around rim


64


of lower wafer


58


. Spring


60


has paddles or ends


78


and


80


which sandwich upward projection


72


on lower wafer


58


and downward projection


74


on upper wafer


62


aligning lobe


68


of lower wafer


58


with extension


70


of upper wafer


62


.




Lower wafer


58


and upper wafer


62


are releasably locked together through spring


60


. The drive force from head motor


32


on lower wafer


58


and upper wafer


62


is not enough to overcome the tension of spring


60


, and hence, spring


60


restrains upper wafer


62


such that as a unit, lower wafer


58


and upper wafer


62


, remain stationary when head


12


is rotated by motor


32


.





FIG. 6

demonstrates the effect of spring


60


when head


12


is forcibly physically turned from an operational position without head motor


32


or when body


25


and/or feet


28


are rotated while holding head


12


stationary. Spring


60


acts as a protective safety device or mechanism, which increases the useable life of doll


10


by preventing the gears from being stripped or otherwise misaligned within head assembly


48


when an external force is exerted on head


12


. Physically wrenching head


12


to one side, or rotating body


25


while holding head


12


still, exceeds the tension of spring


60


thereby permitting lower wafer


58


to move independently of upper wafer


62


. Lower wafer


58


follows the rotation of head


12


, while upper wafer


62


follows the position of body


25


.




For example, as shown in

FIG. 6

, head


12


has been forcibly turned to the right from an operational position such that head


12


is in position C shown in FIG.


3


. The force exerted by spring


60


is exceeded and lower wafer


58


follows the rotation of head


12


and contact surface


76


engages limit switch


54


. However, upper wafer


62


remains in its original position in line with the center plane of body


25


of doll


10


. Paddle


78


of spring


60


rests on the outside of downward projection


74


on upper wafer


62


and paddle


80


of spring


60


rests on the outside of upward projection


72


on lower wafer


58


. As head


12


is forcibly rotated, lower wafer


58


follows rotation of head


12


and spring


60


is drawn apart. Once pressure is released from head


12


, spring


60


biases head


12


and lower wafer


58


back to the resting and motor operation position where lobe


68


of lower wafer


58


is aligned and parallel with extension


70


of upper wafer


62


as shown in FIG.


5


.




Head position assembly


48


has additional safety mechanisms. Physical stops


82


,


84


, shown in

FIGS. 5 and 6

, prevent a child from turning the doll's head beyond a predetermined range. Stops


82


and


84


work in combination with spring


60


to prevent head position assembly


48


from becoming inoperable due to a child's play. Head position assembly


48


includes a stopping surface that engages stops


82


and


84


when head


12


is physically rotated beyond the predetermined range of positions. Moreover, as illustrated in FIG.


6


and described above, spring


60


is drawn apart as the tension of spring


60


is exceeded and head


12


is forcibly turned. The stopping surface on head position assembly


48


contacts stop


82


or


84


, and when the physical pressure on head


12


is released, head


12


is biased by spring


60


back to the resting position or operation position, (shown in

FIG. 5

) where lobe


68


on lower wafer


58


is aligned with extension


70


on upper wafer


62


.




Alternative mechanisms for head position assembly


48


are contemplated. For example, gear


46


may engage upper wafer


62


or an intermediate wafer (not shown). Likewise, limit switches


50


,


52


, and


54


may be positioned such that upper wafer


62


engages contact with the switches. Moreover, upper wafer


62


may turn with head


12


, when head


12


is forcibly turned, while lower wafer


58


remains stationary.




A second interactive feature of doll


10


is the animation of eye assembly


20


. As described previously, eye assembly


20


includes eyes


22


and eyelids


24


. In

FIG. 1

, eyelids


24


are moveable, as indicated by arrows


104


about a substantially horizontal axis


106


. For example, as illustrated in

FIG. 1

, eyelids


24


are moveable between an open position D and closed position E.





FIG. 7

shows a representation of a single eye


22


and eyelid


24


. Open eye position D is shown where eyelid


24


is raised. Closed eye position E is shown by a dashed line representing the position of eyelid


24


. In the closed eye position E, eyelid


24


extends downward over eye


22


such that eye


22


is substantially covered by eyelid


24


. Eye motor


34


drives the motion of eyelid


24


, which is a separate motor from head motor


32


, which drives head position assembly


48


. By using separate motors for head rotation and eyelid motion, head rotation can operate independently and out of sequence with eyelid motion and vice versa.





FIG. 8

shows details of an eye assembly mechanism. Eye motor


34


drives gears or other suitable mechanical system to effect eyelid


24


to be able to move between open position D and closed position E. Eyelid


24


is configured to contact a position monitoring structure or limit switches


130


and


132


when in the corresponding positions D and E. Each limit switch is coupled to processor


56


, which then drives eye motor


34


and eye assembly mechanism. Processor


56


, which controls the eye assembly mechanism, may be the same processor that directs head position assembly


48


. Alternatively, two separate processors may be used, with or without communication between the processors.




Doll


10


may also have additional interactive features. As shown in

FIG. 9

, doll


10


may have a plurality of detachable/attachable accessories or external components, which may be removably attached to doll


10


. These accessories may be shaped to identify a particular activity. For example, the accessories may include a diary


200


, a telephone


202


, a handbag


204


, or any other object. Each accessory preferably has a contact region


206


, which may be matched with a corresponding contact region or communication port


208


on doll


10


. Contact region


206


may be read electronically by a microprocessor, such as processor


56


, through the incorporation of a resister, capacitor, memory chip, or other electronic element.




By way of illustration,

FIG. 9

shows contact region


208


, which is positioned on the top of the doll's hand. Each accessory may be removably attached to the doll's hand to elicit a predetermined response. Once the contact region


206


of each accessory engages the contact region


208


on doll


10


, the information regarding the attached accessory is relayed to processor


216


. Processor


216


recognizes which accessory has been attached and responds according to the particular accessory attached to contact region


208


. Processor


216


may be a separate processor from the processors described above, or alternatively processor


216


may be the same processor that controls head position assembly


48


or the eye assembly shown in

FIGS. 7 and 8

.




The particular accessory attached to doll


10


effects a particular response. For example, if diary


200


is attached to contact region


208


of doll


10


, then doll


10


responds with diary interactive response


210


. Likewise, if telephone accessory


202


or handbag


204


is attached to contact region


208


, then doll responds with associated responses


212


or


214


, respectively. The interactive responses may include pre-recorded speech or games, which may be emitted from a speaker


218


. Speaker


218


may be contained anywhere in doll


10


, such as head


12


, body


25


, or feet


28


. Alternatively, the interactive responses may include doll


10


opening and closing eyelids


24


or rotation of head


12


. Moreover, interactive responses may include any other electromechanical response.





FIG. 10

shows another interactive feature of doll


10


using a different communication port and different external components. Doll


10


may have a plurality of detachable/attachable clothing that allows a child to dress doll


10


. Doll


10


may then respond according to the particular outfit attached to doll


10


. For example, as shown in

FIG. 10

, doll


10


may have attachable tops


300


, dresses


302


, skirts


304


, pants, shorts or other articles of clothing or accessories. Each article of clothing has at least one contact region


306


(similar to contact


206


) that corresponds to at least one contact or communications port on body


25


of doll


10


. Doll


10


, as shown, has two contacts, an upper torso portion of contacts


316


, and a lower body pair of contacts


318


, which are similar in function to contacts


208


.




When doll


10


is dressed in the attachable clothing, information regarding the outfit on doll


10


is relayed to processor


320


. Processor


320


may be the same processor as the processor used for any or all of the above described interactive features of doll


10


. Alternatively, processor


320


may be an independent processor. Processor


320


recognizes which outfits are on doll


10


and responds accordingly. Hence, if top


300


is attached to doll


10


, then processor


320


will direct a predetermined response


310


associated with top


300


. Similarly, if dress


302


or skirt


304


is attached to doll


10


, then doll


10


will respond with the associated response


312


or


314


, respectively. Moreover, different shaped or colored tops, dresses, skirts, shorts, etc. all may elicit variable responses from doll


10


.




Responses associated with each of the outfits attached to doll


10


may include speech or games through speaker


322


. Speaker


322


may be the same speaker as speaker


218


or may be an alternative speaker. Moreover, speaker


322


may be positioned anywhere on doll


10


. Alternatively, doll


10


may respond to the outfits by opening and closing eyelids


24


, rotating head


12


or any other similar electro-mechanical response.




Doll


10


may include additional features, such as user input devices or switches (not shown). The user may be able to direct a response from doll


10


. The user input devices may be positioned anywhere on doll


10


, including head


12


, body


25


, or feet


28


. Similarly, doll


10


may also include an on/off switch for powering motors


32


and


34


. The on/off switch may be located anywhere on doll


10


, for example, on the under-surface of feet


28


.
