DETAILED DESCRIPTION OF THE EMBODIMENTS
While the invention is susceptible to embodiments in many different forms, there are shown in the drawings and will described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention, claims and/or embodiments illustrated.
Referring now to FIG. 1 a system 5 to direct movement of a dancing FIG. 10 is shown in accordance with the embodiments and disclosures herein below. While the FIG. 10 is shown as a female doll, other external features or characters not shown may also be contemplated, such as robots, male characters, insects, animals, etc.
As illustrated, the FIG. 10 includes a pair of feet 15 that are removeably attachable to a base 20 (described in greater detail below). The base 20 is an important aspect of the invention especially for the movement of the FIG. 10. In one embodiment, the base 20 causes movements through a series of linkages and housings that move the FIG. 10. The linkages and housings are pivotally connected to each other at specific areas defined in the ankle region 65, knee region 70 and hip region 75, which permit the legs 60 to bend or pivot at those regions. The FIG. 10 is removable from the base 20 for typical static play, such as changing clothes, etc.
Continuing to refer to FIG. 1, the feet 15 are separately connected to ankle regions 65 that are part of the figure's boot housings 115. Individual legs connect the boot housings through a knee region 70 to the hip regions 75. The FIG. 10 further includes a torso housing 200 which connect the hip regions 75 to the head 210 and to a pair of arms 215. The interior components of the FIG. 10 are best shown and described with reference to FIG. 2.
FIG. 2 shows that the legs, thighs, and torso of the FIG. 10 houses various linkages and components that move the FIG. 10 when the system 5 is operating. The legs 60 are broken into two regions the thigh region and lower leg region. The lower leg region includes the boot housing 115 that includes a calf linkage 140, while the thigh region includes a thigh housing 152 that includes a thigh linkage 150. The calf linkage 140 is secured at the lower end by pin 141, while the upper end is secures to the lower end of the thigh linkage to a knee connector 147. The upper end of the thigh linkage 150 is secured to a portion of the hip connector 175. The hip connector 175 includes a pair of parallel sides 177 that secure to an aperture 179 on a T-bar mount 185. The T-bar mount 185 further includes a channel 203 (explained shortly below). The T-bar mount is housed in the lower section of the torso housing 200.
The torso housing 200 also contains a y-bar mount 202 which includes on its lower end a knob 205 that fits within the channel 203 of the T-bar mount 185. Ends 207 of the Y-bar mount 202 are secured within the torso housing 200. The upper portion of the torso housing 200 also houses a motor 220 that is used to move the arms and head. The motor 220 drives a combo gear 230 that meshes to a pair of crown gears 225 and a neck gear 235. The crown gears 225 separate move the arms 215, which are connected to pins 240, up and down. This is done while the head 210 moves side to side by virtue of its connection to the neck post 236. Greater detail of the movement of the FIG. 10 will be explained below.
Referring now to FIGS. 3 through 4c, the base 20 includes a base plate 25, a housing 30 and a plurality of operation members 32. An integrated circuit (IC) 35, power source 40 and speaker 45 are secured to the base plate 25. First and second drive mechanisms are housed within the base 20 and utilize a first motor 50 and a second motor 55 to power each leg 60 independently of the other. The first and second motors 50 and 55 are in operable communication with two sets of gear trains 120. The two sets of gear trains 120 transfer movement to two upper gears 125, in which both include a cam 130. Each cam 130 extends through a channel 132 in a rotation linkage 100, that when the cam moves causes the rotation linkage 100 to rock back and forth. The rotation linkage 100 also includes a tab 95. The tab 95 extends out through an upper turntable plate 80 that specifically includes footprints 85 sized to receive the feet of the FIG. 10. More specifically the tab 95 extends through a footprint channel 90 in the upper turntable plate 80. In addition to the tab 95 a post 110 also extends through a footprint aperture 105. The tab 95 and post 110 help keep the FIG. 10 secured to the upper turntable plate 80. By locking onto apertures in the bottom of the feet. To release the FIG. 10 the user can push a flange 108 defined by an engagement mechanism 107. The engagement mechanism 107 includes a spring 109 that biases the engagement mechanism 107 such that the feet are secured in place. Pushing the flange 108 compresses the spring and releases the feet.
Referring now also to FIG. 5a, as the gear trains 120 rotate the upper gears 125, the rotation linkages 100 reciprocate back and forth laterally, directed by the cam 130 and channel 132 relationship. As the rotation linkages 100 are moving laterally, the footprints 85 and posts 110 keep the boot housings 115 stationary, while the tab 95 slides back and forth along the channel 90, coming into contact with and moving a lower portion 135 of a calf linkage 140, which rotates the calf linkage 140 about axis 145. The calf linkage 140 is rotatably secured to the thigh housing 152 at axle pivot 146 (shown without the right side outer portions of the thigh housing 152 and boot housing 115 and the left side inner portions of thigh housing 152 and boot housing 115) and is freely rotatable about the axis 145 within the restraints of the boot housings 115. As the calf linkage 140 rotates, the movement is transferred to a thigh linkage 150, which is rotatably secured by knee connector 147 and is rotatable about axis 155 in the knee region 70.
Now additionally referring to FIGS. 5b and 5c, the upper portion 160 on the thigh linkage 150 is pivotally secured to the hip mechanism about axis 170. The hip mechanism or connector 175 is defined as having two pairs of vertical parallel sides 177 with the T-bar 185 pivotally connected therebetween, such that movement of the thigh linkages 150 is transferred to the T-bar 185 in a side to side rocking motion for movement of a torso (described below). Further, the two pairs of vertical sides 175 are pivotally secured to the thigh housing 152 such that the hip mechanism may rotate about axis 191, thus keeping the torso in a substantially upright position. As such, movement of the upper gears 125 on the gear trains 120 directs movement of the legs 60 back and forth, utilizing the pivot points in the ankle region 65 and the knee region 70 while the hip mechanism facilitates side to side movement via the relationship with the upper portions 160 of the thigh linkages 150 as described above. For continuous movement, the lower portion 135 of the calf linkage 140 has a spring 195 to return the calf linkage 140 to its original position.
Now referring back to FIG. 2 and additionally to FIG. 6, the torso drive mechanism is in communication with the power source 40 and the IC 35 for power and operational direction. When the third motor 220 is powered, the third motor 220 directs the combo gear 230 to spin such that the crown gears 225 and neck gear 235 rotate in accordance thereto.
In the first embodiment, the dancing figure and base include a means to trigger preprogrammed content including different dance maneuvers that incorporate movement of the legs, hips, arms and head of the dancing figure. Additionally, the first embodiment includes a means to manually control dance maneuvers that incorporate movement of the legs, hips, arms and head of the dancing figure. Also, the first embodiment includes a means to removeably attach the figure to the base. Further, the first embodiment includes a means to enable movement of the figure by utilizing a combination of gears, linkages and motors. Additionally, the first embodiment includes a means to simulate dance maneuvers utilizing pivots in the ankles, knees, and hips in combination with gears, linkages and motors.
Referring now to FIG. 7, there is shown a block diagram provided for the first embodiment of the FIG. 10. The FIG. 10 includes the IC 35 that contains a processor(s) 245 and a memory 250. The processor(s) 245 accesses preprogrammed signals or audio content stored on the memory 250 in the IC 35. The IC 35 further includes programming and electronic components to facilitate and direct audio content, control signals and data. The processor(s) 245 in the IC 35 accesses the preprogrammed signals or audio content based on a program and/or in accordance to a user's input. The processor(s) 245 than generates a response that includes signals and may be in the form of audio or control signals. The IC 35 is in communication with the speaker 45, the first motor 50, the second motor 55, the third motor 220 and the power source 40. The base 20 would contain components well known in the art to facilitate control capabilities. For example, the base 20 may include the plurality of operation members 32 and processor(s) 245. The plurality of operation members 32 may trigger the selection of different songs and/or a specific dance that corresponds to a particular song. Additionally, the plurality of operation members 32 may include buttons to manually control the movement of the FIG. 10 based on a user's input. The IC 35 receives a user's input from the plurality of operation members 32 transferred through the aforementioned communication stream. From the processor(s) 245, audio signals are transferred to the speaker 45 while control signals are transferred to the first motor 50, the second motor 55 and the third motor 220 to direct the motors to power in a desired direction, based on a program and/or in accordance to a user's input or preprogrammed response. As such, a user can selectively distribute power to the drive mechanisms to direct the FIG. 10 to move in a variety of dance sequences. Further, as the drive mechanisms move, the movement is transferred throughout the FIG. 10 as described above.
It should further be contemplated that the FIG. 10 can include audio content and preprogrammed responses stored in the IC 35. The user may press a power button (or other triggering mechanism) to trigger the preprogrammed responses and audio content stored on the memory 250. The FIG. 10 in response can execute a performance pattern through movement and audio.
From the foregoing and as mentioned above, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the novel concept of the invention. It is to be understood that no limitation with respect to the specific methods and apparatus illustrated herein is intended or should be inferred.
