The present invention relates, in general, to animated toys and more particularly to dolls and figures that are mechanically animated to simulate movements.
Toy figures have long delighted children with various mechanical motions that mimic human gestures, walking and dancing. Generally, affordable animated toys are capable of only very simple movements due to a relatively small number of components and motors. Thus, animated toys capable of complex movements generally have a large number of components and motors and tend to be expensive.
Since the electric motor in an animated toy tends to be the most expensive component, it has generally been the practice for one motor to drive a number of actuating parts through various geared members. Some effects achieved in this way include a doll whose torso twists while the arms move. While initially entertaining, such animations tend to be rather repetitive and not capable of variations necessary for more complex motions with a number of sequential movements.
As an example of a complex motion, a dance that continues to be popular with both children and adults is the Hokey Pokey. Although relatively simple for even the smallest child to do, attempts to incorporate these movements into a toy have been only modestly successful. A toy designed to do the Hokey Pokey as its primary function would tend to be expensive due to the requirements for sequentially putting forward and shaking a leg, an arm, and a head as well as spinning the entire toy round. Consequently, such toys tend to simulate such movements in a nonrealistic way.
At the other extreme, robotic toys that include multiple, independently controlled motorized actuators have been known to include programming to do the Hokey Pokey dance. These toys tend to be multi-functional in order to justify their increased complexity and cost. Thus, the actuation of the various body parts still tends to be disappointing in that their movement is not optimized for the Hokey Pokey.
Consequently, a significant need exists for a toy that can effectively mimic the human movements of a complex dance, yet achieve this effect economically.
The invention overcomes the above-noted and other deficiencies of the prior art by providing a toy that accomplishes a complex dance, such as the Hokey Pokey, with merely two electric motors, yet successfully spins about one foot and sequentially puts forward and shakes a hand, foot and head. Thus, an entertaining toy is achieved without being cost prohibitive.
In one aspect of the invention, a toy includes a torso including an upper half and a lower half pivotally coupled to rotate relative to one another about in a nonvertical axis defining a nonhorizontal plane. The upper portion includes a first arm aligned with a higher portion of the nonhorizontal plane and includes a second arm aligned with a lower portion of the horizontal plane. Thus, as the upper half rotates, the first arm appears to be put forward and down, imitating a common human arm movement. Moreover, a head part of the upper half also tends to tip forward or back in relation to the rotation, further suggesting putting a head forward and back.
In another aspect of the invention, incorporating a shaking mechanism into the toy causes the portion of the toy's body that is put forward to shake.
In yet another aspect of the invention, the toy is weighted and mechanized to spin about one foot to provide additional dance combinations.
These and other objects and advantages of the present invention shall be made apparent from the accompanying drawings and the description thereof.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and, together with the general description of the invention given above, and the detailed description of the embodiments given below, serve to explain the principles of the present invention.
With reference to the drawings, wherein like components are given like reference numbers throughout the several views, in
The upper half 20 of the torso 24 has an upper back shell 28 that attaches to an upper front shell 30. Similarly, the lower half 22 of the torso 24 has a lower back shell 32 that attaches to a lower front shell 34. The torso 24 forms a generally ellipsoid shape bifurcated and spaced about a horizontal or non-horizontal plane having a highest point proximate to the left arm 12, a lowest point below a right arm 36 and level with respect to any front to back chords, forming a diagonal waist 38. (See
Swivel of the upper torso 20 is powered by a waist drive train assembly 40 engaged between the lower rear and front shells 32, 34 and projecting a waist drive shaft 42 approximately centered and perpendicular to the diagonal waist 38 to engage the upper half 20 of the torso 24. Advantageously, this engagement for rotation relative to the diagonal waist 38 allows pivoting between the upper and lower halves 20, 22 of the torso 24 with respect to a lateral axis. To this end, a torso pivot bracket 44 extends between the upper rear and front shells 28, 30 of the upper half 20 of the torso with a rear pin 46 aligned with a front pin 48 received respectively within a rear pivot hole 50 in the upper rear shell 28 and a front pivot hole 52 in the upper front shell 30. The torso pivot bracket 44 has sufficient lateral width to be stabilized against a top surface 54 of the waist drive train assembly 40 while engaging the waist drive shaft 42 through a center through hole 56. A mousetrap-style spring 58 is retained on the rear pin 46 and engages the torso pivot bracket 44 and the upper rear shell 28 and is preloaded to exert a pivoting force to tip the head 14 toward the left.
The right arm 36 is rigidly attached by being pinned between the upper rear and front shells 28, 30. The left arm 12 has a transverse pin 60 that pivotally engages to an arm receptacle 62 formed between the upper rear and front shells 28, 30. A range of pivoting movement of the left arm 12 is thereby defined about this transverse pin 60 as angularly constrained by an inward tab 64 of the left arm 12 that allows movement between physical limits inside of the upper half 20 of the torso 24. Rotation of the upper half 20 causes the left arm 12 to rotate somewhat farther in the direction of rotation due to tab 64 making contact with the stem protruding from gear box 40. The left arm 12 also has sufficient flexibility to vertically shake in response to lateral pivoting oscillation of the upper half 20 of the torso 24.
The right leg 16 has a transverse pin 70 that is engaged with a leg receptacle 72 formed between the lower rear and front shells 32, 34. The right foot 16 is allowed a forward pivoting movement with respect to the lower half 22 of the torso 24 when a kick tab 74 that extends downward on the right side of the upper rear shell 28 forwardly engages the backside of the right leg 16 as the upper half 20 of the torso 24 rotates the left arm 12 to the rear.
A spin/shake drive train assembly 80 is enclosed by an outer shell 82, an inner shell 84, and a foot bottom battery case 86 that form a left foot assembly 88 that rigidly attaches to a left leg portion 90 of the lower half 22 of the torso 24. A battery compartment 92 is formed by the foot bottom battery case 86 as covered overtop by a motorized gearbox 94 and is selectively closed in front by a battery door 96. A vertical spin shaft 98 extends downwardly from the motorized gearbox 94 through a rearwardly open slot 100 in the foot bottom battery case 86 to a spin disk 102 that is plastic or may be die cast of metal for weight and additional stability. The positioning and weighting of the other components of the toy 10 are such that the toy 10 may spin about the spin disk 102 as the motorized gearbox 94 turns the vertical spin shaft 98.
Upwardly projecting from the motorized gearbox 94 is a vertical shaker shaft 104 that extends up to a left portion of the diagonal waist 38 to present shake cam 106 to the upper half 20 of the torso 24. The shake cam 106 presents a face aligned with diagonal waist 38 at one portion of the rotation, allowing the upper half 20 to tip left under the urging of its weight and the spring force of the mousetrap-style spring 58. Further rotation of the shake cam 106 causes the upper half 20 to tip to the right. Thus, rapid rotation of the shake cam or any type of eccentric linkage 106 causes a left to right oscillatory shaking of the upper half 20 of the torso 24 that is transferred through to other portions of the toy 10.
A DC motor (not shown) within the motorized gearbox 94 is powered by batteries 108 (
The toy 10 advantageously includes voice and music recordings to enhance interaction with the toy 10. An audio speaker 110 rests upon the torso pivot bracket 44 such that the voice of the toy 10 is directed within the upper half 20 out through a neck hole (
In use, the toy 10 performs the Hokey Pokey dance as illustrated in
While the afore-described toy 10 advantageously performs movements that convincingly mimic human dancing, it is further desirable to reduce the number of motors from two to one in order to enhance economical manufacturing. To that end, in
The upper half 208 of the torso 212 has an upper back shell 214 that attaches to an upper front shell (not shown) about an upper inner frame 217. Similarly, the lower half 210 of the torso 212 has a lower back shell 218 that attaches to a lower front shell (not shown) about a lower inner frame 221. The torso 212 forms a generally ellipsoid shape bifurcated and spaced about a horizontal or non-horizontal plane having a highest point proximate to the left arm 202, a lowest point above the right leg 204 and level with respect to any front to back chords, forming a diagonal waist 222.
A spin/shake drive train assembly 225 secures the lower half 210 of the torso 212 and serves to spin the toy 200 about the left leg 206, swivel the upper half 208 of the torso 212 to put forward the left arm 202, shake the left arm 202, put forward the right leg 204 and shake the right leg 204. The spin/shake drive train assembly 225, shown partially disassembled in
The vertical shaft 227 also includes an upper portion 242 (
The engagement disk 260 includes a downwardly projecting engagement pin 263 and an upwardly projecting engagement pin 267. The upper clutch disk 254 includes a circumferential groove 255 in its top surface 256 for engagement with the downwardly projecting engagement pin 263 of the engagement disk 260. The circumferential groove 255 includes a first extreme portion 257 (most clockwise from top view) and a second extreme portion 258 (most counterclockwise from top view). The arc measure of the circumferential groove 255 may be in the range of about 45° to nearly 360°. In the illustrative version, arc measure is just over a half rotation that, given the diameter of the downwardly projecting engagement pin 263, allows for at least a half rotation relatively between the engagement disk 260 and upper clutch disk 254.
The lower body bevel gear 270 includes an arc recess 272 (
The DC motor within the motorized gearbox 201 may be powered by batteries, which may be stored within the left foot 237 (
At the initial rotation of the engagement disk 260, the upwardly projecting engagement pin 267 floats freely within the arc recess 272 of the lower body bevel gear 270. With continued rotation in a direction, eventually, the upwardly projecting engagement pin 267 will be rotated into the first end 274 or second end 276 of the arc recess 272, and any further rotation of the upwardly projecting engagement pin 267 into the end 274, 276 will communicate the rotation of the engagement disk 260 to the lower body bevel gear 270, thereby causing the lower body bevel gear 270 to rotate concurrently with the engagement disk 260, clutch assembly 250 and motorized gearbox 201.
The upper half 208 of the torso 212 pivots about an upper body axle 300 extending upwardly from the lower inner frame 221 and aligned perpendicularly to the non-horizontal (diagonal) waist between the body halves. The upper body axle 300 extends through an upper body spur gear 310 and a switch plate 320, both of which are rigidly secured to, or integral parts of, the upper inner frame 217. The lower body bevel gear 270 engages the upper body spur gear 310 and rotation of the lower body bevel gear 270 communicates rotation to the upper body spur gear 310 thereby pivoting the upper half 208 of the torso 212 about the upper body axle 300. Clockwise rotation of the motorized gearbox 201 about the vertical shaft 227 results in a counterclockwise, or backward, rotation of the upper half 208 of the torso 212 about the upper body axle 300. Counterclockwise rotation of the motorized gearbox 201 about the vertical shaft 227 results in a clockwise, or forward, rotation of the upper half 208 of the torso 212 about the upper body axle 300. Additionally, a torsion spring 315 (
The upper body axle 300 includes a cam 330 rigidly attached to the upper body axle 300 above the switch plate 320. The switch plate 320 has an arm-in switch 323 and a leg-in switch 326. As the upper half 208 of the torso 212 rotates about the upper body axle 300, the arm-in switch 323 or leg-in switch 326 are rotated towards the cam 330 to eventually contact the cam 330.
Initially, contact between the cam 330 and either switch 323, 326 is used by control circuitry (not shown) to determine when the toy 200 has reach its full movement in one direction prior to clutch slippage. As discussed below, the control circuitry may remove power to the DC motor, thereby ceasing communicated rotation of the upper half 208 of the torso 212 about the upper body axle 300. Alternatively, the circuit may continue to actuate the DC motor in the same rotational direction whereupon the lower body bevel gear 270 reaches its stop against the upper body spur gear 310, causing the lower clutch plate 252 to slip against the upper clutch plate 254, their radial ridges surfaces creating a shake against compression spring 233. Alternatively or in addition, contact between the cam 330 and either switch 323, 326 also serves to physically impede further rotation to initiate the shaking. This shaking of the toy 200 may occur when either the left arm 202 or right leg 204 has been placed forward, or “in” for the purposes of the Hokey Pokey dance. The extension of these respective parts enhances the shake at their extremities, thereby creating an impression that the left arm 202 or right leg 204 are being shook.
The left arm 202 pivotally engages an arm receptacle 405 of the upper inner frame 217. The lower inner frame 221 includes a stop 420 to engage a tab 415 of the left arm 202. When the upper half 208 of the torso 212 is rotated clockwise relative to the lower half 210 as in
The right leg 204 pivotally engages the lower inner frame 221 at a leg axle 425. The upper inner frame 217 includes a prong 430 to engage the right leg 204. When the upper half 208 of the torso 212 is rotated counterclockwise relative to the lower half 210 as in
In use, with reference to
Counterclockwise rotation of the lower body bevel gear 270 causes clockwise rotation of the upper body spur gear 310, resulting in clockwise or forward rotation of the upper half 208 of the torso 212 about the upper body axle 300. As the upper half 208 of the torso 212 is rotated clockwise, the tab 415 of the left arm 202 eventually engages the stop 420 of the lower inner frame 221, thereby rotating the left arm 202 forward. Also, simultaneous with or shortly after the left arm 202 is rotated forward, the arm in switch 323 and cam 330 make contact.
Once ARM-IN POSITION 510 is achieved, in STEP 2, the upper half 208 of the torso 212 of the toy 200 returns to REST POSITION (START/FINISH) 505 as follows. Contact between the arm in switch 323 and cam 330 sends a signal to the control circuitry, which cuts power to the DC motor, ceasing all rotation due to the DC motor, which, in turn, allows the torsion spring 315 to rotate the upper half 208 of the torso 212 counterclockwise about the upper body axle 300 returning the upper half 208 to REST POSITION (START/FINISH) 505.
In STEP 3, once the upper half has been returned to REST POSITION (START/FINISH) 505, the upper half 208 is again moved to ARM-IN POSITION 510 as described above. In STEP 4, at the appropriate point in a recorded musical song, the control circuitry then drives the DC motor further and the toy 200 proceeds to SHAKE ARM POSITION 515 as follows. With the DC motor attempting further clockwise rotation of the toy 200 with the arm in switch 323 in contact with the cam 330, the arm in switch 323 acts as a physical stop to such further rotation resulting in the lower clutch disk 252 slipping against the upper clutch disk 254 thereby shaking the toy 200.
In STEP 5, once the toy 200 has shook for a predetermined amount of time, the DC motor is rotated in the opposite direction to cause counterclockwise direction of the toy 10 for about a full rotation, resetting the spin/shake drive train assembly 225 from one extreme of its travel to the other. Thus, at REST POSITION 518, which is slightly more counterclockwise than the REST POSITION (START/FINISH) 505, the cam 300 makes initial contact with Leg-In switch 326.
In STEP 6, the toy 200 moves the upper half 208 to LEG-IN POSITION 520, defined as the right leg 204 pivoted forward and the leg in switch 326 and cam 330 in contact, as follows. Power to the DC motor initiates counterclockwise rotation of the toy 200 about the spin disk 240. As the toy 200 spins counterclockwise, the clutch assembly 250 spins relatively clockwise and the downwardly projecting pin 263 of the engagement disk 260 is eventually engaged at the second extreme portion 258 of the circumferential groove 255 of the upper clutch disk 254. With the downwardly projecting pin 263 engaged at the second extreme portion 258, the engagement disk 260 begins to rotate concurrently with the clutch assembly 250, and, eventually, the upwardly projecting engagement pin 267 engages the second end 276 of the arc recess 272 of the lower body bevel gear 270, which communicates further clockwise rotation to the lower body bevel gear 270.
Clockwise rotation of the lower body bevel gear 270 causes counterclockwise rotation of the upper body spur gear 310 resulting in counterclockwise, or backward, rotation of the upper half 208 of the torso 212 about the upper body axle 300. As the upper half 208 of the torso 212 is rotated counterclockwise, the prong 430 of the upper inner frame 217 eventually engages the right leg 204 thereby rotating the right leg 204 forward. Also, simultaneous with, or shortly after the right leg 204 is rotated forward, the leg in switch 326 makes full travel contact.
Once LEG-IN POSITION 520 is achieved, in STEP 7, the upper half 208 of the torso 212 of the toy 200 returns to REST POSITION 518 as follows. The DC motor is rotated to cause the toy 10 to rotate clockwise. The torsion spring 315 rotates the upper half 208 of the torso 212 clockwise about the upper body axle 300 returning the upper half 208 to REST POSITION 518. As cam 330 releases from Leg-In switch 326, the control circuitry knows that the REST POSITION 318 has been reached.
In STEP 8, the upper half 208 is again moved from REST POSITION 518 to LEG-IN POSITION 520 as described above until the Leg-In switch 326 is to full travel. At the appropriate point in the musical song, in STEP 9, the DC motor attempts to drive the spin/shake drive train assembly further clockwise (i.e., toy 200 counterclockwise) to LEG SHAKE POSITION 525. Being prevented from doing so, the clutch disks 252, 254 slip and cause shaking. Thereafter, the control circuitry initiates clockwise rotation of the toy 200 back to the REST POSITION (START/FINISH) 505 wherein initial contract is made with the Arm-In switch 323.
The toy 200 may include a mechanism for playing voice and music recordings, which may also be controlled via the control circuitry such that the recordings are played in coordination with the movement of the toy 200. Additionally, the toy 200 may be powered by AC. Also, the toy 200 may also include a radio or remote controls to control all or part of the movement.
While the present invention has been illustrated by description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications may readily appear to those skilled in the art. For example, although the Hokey Pokey dance is enabled in the illustrative version, other dances and human mimicry may be achieved consistent with aspects of the invention.
