Abstract
Abstract A dancing doll which alternately moves its hips left and right while alternately rotating 180° clockwise and counterclockwise to a melody. The doll includes an upper portion, a hip portion, a leg portion, and a base portion. The upper portion resembles the head to hip portion of a human; the hip portion resembles the hips of a human; and the leg portion resembles the legs through feet of a human. The base portion includes a covering case with a rotating disc at its bottom, a base plate that is pivotally connected to the rotating disc, a switch, a battery, a motor, an I.C. Unit, a speaker, a prime gear, a cam, an actuator, and gearing which will transmit the motion of the motor to the cam and to the actuator and will cause the alternate turning of the rotating disc. A pin pivotally connects the upper portion to the hip portion and a torso supporter, which extends from the right leg into a cavity in the upper portion. The feet are connected to the top of the covering case. An actuating rod passes through the covering case and left leg and is connected at one end to the actuator and at the other end to the hip portion. When the switch is turned on, the motor moves the actuator up and down which alternately moves the hips of the doll left and right and turns the cam that in turn alternately moves the doll in a clockwise or counterclockwise direction while a melody is heard.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
A dancing doll comprising an upper portion, a hip portion, a leg portion, and a base portion; said upper portion and said hip portion each defining respective cavities; said leg portion comprising two legs, one of said legs further comprises an integrally connected torso supporter, said torso supporter comprising an elongated extension of said one of said legs; said torso supporter extending into said cavity of said upper portion; said torso supporter having a pivotal connection for pivotably attaching said upper portion and said hip portion to said torso supporter; the base portion includes a covering case with a rotating disc attached to its bottom and a base plate that is pivotally connected to the rotating disc; the legs have feet and said feet are connected to the top of the covering case; means are connected to the covering case for alternately turning the covering case counterclockwise and clockwise for a predetermined distance; an actuator is operatively connected to said turning means, and said actuator is connected to means for connecting said actuator and said hip portion for moving the hip portion about said pivotal connection by reciprocating action.
Claim 2
Dependent Claim
189 words
A dancing doll comprising an upper portion, a hip portion, a leg portion, and a base portion; said upper portion and said hip portion each defining respective cavities; said leg portion comprising two legs, one of said legs further comprises an integrally connected torso supporter, said torso supporter comprising an elongated extension of said one of said legs; said torso supporter extending into said cavity of said upper portion; said torso supporter having a pivotal connection for pivotably attaching said upper portion and said hip portion to said torso supporter; the base portion includes a covering case with a rotating disc attached to its bottom and a base plate that is pivotally connected to the rotating disc; the legs have feet and said feet are connected to the top of the covering case; means are connected to the covering case for alternately turning the covering case counterclockwise and clockwise for a predetermined distance; an actuator is operatively connected to said turning means, and said actuator is connected to means for connecting said actuator and said hip portion for moving the hip portion about said pivotal connection by reciprocating action.
Claim 3
Dependent Claim
44 words
The dancing doll of claim 1, with a switch connected to the the actuator and circuit means for playing an electronic melody, a speaker, and said speaker and said circuit means are connected to a means for accepting a battery within the covering case.
Claim 4
Dependent Claim
267 words
The dancing doll of claim 2, wherein the means for alternately turning the covering case counterclockwise and clockwise for a predetermined distance includes a motor, a primer gear and two additional spaced gears on a main shaft, a gear on a cranking shaft, a spring and at least two spaced gears on a cam-actuated shaft, two spaced alternate gears and a third gear on a cam shaft with a cam connected to one end of the cam shaft, two spaced gears on a bevel gear shaft with a bevel gear connected to one end of the bevel gear shaft, two spaced gears on a last shaft, a bevel rotation gear, and two spaced support panels; said prime gear is connected to the shaft of the motor and meshes with one of the gears on the main shaft; the other gear on the main shaft meshes with one of the gears on the cam-actuated shaft and with the gear on the cranking shaft; the other gear on the cam-actuated shaft alternately meshes with the two alternate gears depending on the position of the cam; one of the alternate gears meshes with one of the gears on the bevel gear shaft; the third gear on the cam shaft meshes with one of the spaced gears of the last shaft; the other spaced gear on the last shaft meshes with the other one of the gears on the bevel gear shaft; the bevel gear meshes with the bevel rotation gear through a slot in the rotating disk; and all of the shafts are supported by the two spaced support panels.
Claim 5
Dependent Claim
93 words
The dancing doll of claim 3, wherein the means for moving the hip portion by reciprocating action of the actuator includes, a bracket and an actuating rod; the actuator is connected at one end to one end of the cranking shaft and at the other end to one end of the actuating rod; the bracket is secured to the side of one of the support panels so that the actuator passes through the bracket; and the actuating rod passes through the left leg and its other end is connected to the hip portion.
