1. Field of the Invention
The present invention relates to the field of dolls, and more particularly, to animated dolls.
2. Prior Art
Dolls of various kinds, shapes, sizes, materials and construction are well known in the prior art. Also known are dolls having some form of animation. Typically animation is provided by a power source such as battery power with internal sound generation and motor driven internal linkages coupled to move one or more body parts, such as eyes and mouth, as in the Teddy Ruxpin Talking Teddy Bear popular a number of years ago. Alternatively, the animation mechanism and power source may be provided under a platform on which the doll stands to provide some form of animation in the doll. By way of example, U.S. Pat. No. 6,887,121 discloses a toy comprising a flexible doll with magnets in the doll's feet to hold the doll upright on a platform. In one embodiment, one foot is magnetically held stationary with the position of the other foot being manipulated to simulate dance by the motion of a magnet under the platform on which the doll is standing. Magnets may also be placed in the hands of the doll to similarly be attracted to a fixed metal bar. Thus the source of the animation is entirely external to the doll. The doll, however, is removable from the platform for other play by physically overcoming the magnetic attraction of the doll's feet to the platform on which it may be standing.
U.S. Pat. No. 5,941,756 discloses a motion toy which provides motion in a mechanism above a platform through a drive system beneath the platform. No application of the mechanism to dolls is mentioned.
U.S. Pat. No. 6,022,263 discloses mechanical toy figures which are mechanically animated as powered by springs within the mechanical toy figures after the mechanical toy figures are set to an initial starting condition. Various body part motions are coordinated by mechanisms within the figures.
U.S. Pat. No. 6,126,508 discloses a motion toy which includes animation mechanisms within the doll-like toy that are, in effect, mechanically powered from a source of power in the platform on which the motion toy stands. That motion comprises a sidewise tilting of one leg of the toy, causing the second leg to similarly tilt, moving the hips of the toy in a first sidewise direction, causing the mechanism to somewhat rotate the body in the opposite direction and to tilt the head in the same direction as the legs. The toy is permanently mounted on the platform on which it stands.
U.S. Pat. No. 6,200,191 discloses a structure of motion toy having a somewhat similar motion as the '508 patent. In this motion toy the hips move sidewise while the body tilts somewhat in an opposite direction, no head being shown on the toy illustrated. The toy is powered by a motor within the toy, though no source of power for the motor is disclosed. The toy is self contained, apparently intended to stand upright on any flat surface.
In U.S. Pat. No. 4,676,764 a dancing doll with hip movement and 180° rotation is disclosed. The doll stands on a rotatable platform driven in rotation, with a cam raising and lowering one leg, causing the hips to move side to side.
In U.S. Pat. No. 4,040,206, a base and rotatably mounted doll with relatively moveable parts is disclosed. The doll stands on a platform with a manually operated drive mechanism in the platform for rotating a rod up through the leg of the doll. The leg may be fixed or allowed to rotate, in the first case, mechanism within the doll being powered by the rod in the leg cause animation of the doll, whereas in the second case, the doll simply rotates about that leg.
U.S. Pat. No. 5,412,890 discloses a nested turntable arrangement for electronically animated characters. The nested turntable arrangement has a base turntable rotatable about a base axis and pedestal turntables supported on the base turntable for independent rotation about separate pedestal axes. It is stated that animated characters are mounted on the pedestal turntables that have an arm body part segment whose hand ends can be extended and brought into juxtapose position approximate the base axis under rotation of the pedestal turntables. No animation of the individual characters is shown other than the rotation of the character by rotation of the respective pedestal. Proportional feedback of the base turntable rotation and the pedestal turntables rotation is disclosed.
Finally, in U.S. Pat. No. 6,682,392 physically interactive electronic toys are disclosed. Each electronic toy has at least one moving part and comprises a preprogrammed integrated circuit in at least one electric motor adapted to perform actions. Multiple such toys may be interconnected in different combinations and programmed to interact in groups of two or more. Each electronic toy is in the form of a character mounted on a rotating table which may be plugged into a similar toy for coordinated action of the electronic toy. The rotating table is shown to support a human-like character with the figure containing multiple electric motors adapted to move specific moving parts of the figures in specific ranges of motion. Only one such motor is shown for simple head rotation and no details are provided as to how power is supplied to those motors, though they are controlled from the base of the toy. No details are provided with respect to the animation mechanism in the character or the mounting of the character on the rotating table.

The present invention comprises animated dolls that removably stand on a platform by magnetic attraction, but are physically removable from the platform for other play. The dolls are electrically powered by contacts in the doll feet cooperatively disposed with respect to electrical contacts on the platform. In preferred embodiments, the dolls are fashion dolls, and as such, are of rather trim physiques not allowing for containment within the doll of significant electrical power for the animation, hence the electrical power and control from the platform. From Wikipedia, the free encyclopedia on the Internet, fashion dolls are defined as “dolls designed to be dressed and redressed to reflect fashion trends or occasionally fantasy play. The dolls are typically plastic or vinyl, and are manufactured both as toys and as collectibles. They are enjoyed by many age groups. The dolls are usually modeled after teen girls or adult women. Sizes range from 10.5 inches (270 mm) to 24 inches (610 mm). There are of course some special cases that fall outside this range. 11.5 inches (290 mm) is the size of the Barbie doll, by Mattel, who set quite a standard for many years in this arena.”
In the description to follow, various embodiments are disclosed. All include a doll that stands by magnetic attraction in a specific location on a platform that rotates and receives electrical power from the platform to power some form of animation in the doll, such as sound, lights and/or physical motion of one or more body parts. In one embodiment disclosed, head, body and arm movements are provided by control of a single animation motor in the body using proportional feedback back to a controller in the base supporting the platform for more lifelike doll motion. In one incarnation of this embodiment, each arm moves as a unit, though the bend of the elbow may be manually preset, while in another incarnation, upper and lower arm segments move relative to each other in unison with the upper arm motion. In another embodiment, the legs are individually rotatable relative to the hips through at least a limited angle to allow sidewise motion of the hips by tilting of the doll feet.
There are also various embodiments of the base supporting the platform. In one base embodiment the platform simply rotates, though the angular rotation is controllable so that the platform may be rotated back and forth through different angles as a partial simulation of dancing. In another embodiment the magnetically preferred doll feet positions on the platform are each tiltable about a respective one of two axes, the two axes being in a plane substantially parallel to the remaining surface of the platform and each generally aligned with the length of the respective doll foot, whereby tilting the foot surfaces in unison with the doll standing on the platform will cause the dolls' hips to move side to side. This tilting is achieved in the specific embodiment disclosed by a cam action active on rotation of the platform. The remaining animation of the doll may be as previously described, resulting in body, arm and head motion.

The electrical connection to the permanent magnets is made through wiper contacts 132 connected to the rotating platform 114 and contacting non-rotating slip rings 134. It will be noted that in addition to the five slip rings, there are four arc segments of an additional slip ring 136 and six wipers on the wiper assembly 132. The slip ring arc segments 136 are used to sense the angular position of the platform 114. In particular, in a preferred embodiment the wiper positioned to contact the arc segments 136 is electrically shorted on the wiper assembly 132 to the adjacent wiper which always has a voltage thereon so as to be able to sense the position of the platform 114 by the presence or absence of the corresponding voltage on an O-ring arc segment 136. Also shown in
Now referring to
Thus when the doll is in place on the platform 114, the doll's body and head may gyrate or rotate, and the arms swing to the music played by the controller, with bending of the elbows if the doll is so configured, as the platform 114 rotates in a controlled manner back and forth through angular increments as defined by the start and ends of the slip ring arc segments 136.
Now referring to
a is an exploded prospective of an alternate embodiment of platform, and
There has been described herein various embodiments of dolls and platforms on which they may stand for varied animation, or removed for normal doll play. Thus the present invention has a number of aspects, which aspects may be practiced alone or in various combinations or sub-combinations, as desired. Also while certain preferred embodiments of the present invention have been disclosed and described herein for purposes of exemplary illustration and not for purposes of limitation, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
