The doll includes a rotatable shaft which is movable along its axis of rotation from a neutral position to an upward position in which the shaft engages a crankshaft assembly to cause the dolls legs to move with respect to the dolls torso to produce a stepping motion. The rotatable shaft is also movable to a downward position in which the shaft drivingly engages a licor-contacting member which is inhibited from rotating thereby causing the drive train and the motors housing, which is connected to the dolls torso, to rotate and to rotate the torso therewith. The dolls head is coupled to the torso with a torsion spring, which forms part of a head-spotting assembly. The latter is used to inhibit the rotation of the head during a xed preselected portion of each revolution of the dolls torso.
BACKGROUND OF THE INVENTION (1) Field of the invention The present invention relates to an animated toy and, more particularly, to an animated toy, capable of performing one or more complex motions.
(2) Description of the prior art One of the primary goals of toy designers is to develop reasonably priced animated toys, which can be operated safely and easily by children. This goal has been achieved quite often in the development of the many types of toy guns. Also, several kinds of animated dolls have been designed. Most of the animations, performed by such dolls., have been limited to relatively simple combinations of eye, lip, head or limb movements. Herebefore, the development of dolls capable of complex steps or movements has been generally very limited due to the difficulties encountered in the animation of complex steps, with a relatively simple, reliable and relatively inexpensive mechanism, which can be operated safely and easily by a child.
It is primarily for the above-mentioned reasons that prior art ballerina-type dolls are typically of the nonanimated type, since the animation of the complex steps performed by a ballerina were found to be too diflicult to implement with a simple, reliable and relatively inexpensive mechanism.
OBJECTS ANlD SUMMARY OF THE INVENTION It is a primary object of the present invention to provide an animated doll, capable of performing any one or several complex motions.
Another object of the invention is to provide a relatively simple, reliable operable animated doll which is power operated to perfrom linear and/or rotational movements.
Yet another object of the present invention is to pro- 3,611,625 Patented Oct. 12, 1971 ICC vide a power-driven ballerina doll which can be operated with ease by a child to animate one or more of traditional ballet-type motions.
'A further object of the invention is to provide a poweroperated animated toy capable of performing a plurality of complex steps including linear and/ or rotational motions.
These and other objects of the invention are achieved by providing a toy, for example, a doll with limbs, selectively coupled to a hollow torso, in which a source capable of providing rotational motion is located. A multi-position switch which is used to control the motions which the doll is to perform is located in the dolls interior. The switch, is actuatable from the dolls exterior, for example, by the application of forces, to be described hereafter in detail, to one of the dolls arms. When the switch is activated to be in a lfirst position, the source of rotational motion is rotatably coupled to a first step-controlling assembly which is also coupled to the dolls legs, transmitting linear motion thereto, so that the dolls legs animate a walking or stepping motion. When incorporated in a ballerina-type doll, the stepping motion simulates the motion -known in ballet as a pas de bourre.
By merely changing the switch position to a second position the `first step-controlling assembly is disengaged from the source and a second step-controlling assembly becomes engaged therewith. In one embodiment, the latter-mentioned assembly includes a shaft with a first end thereof extending through one of the dolls legs. By supporting the doll in an axis perpendicular to a surface with which the shafts flirst exposed end is frictionally engaged, the shaft is inhibited from rotating, causing the dolls body to rotate. When incorporated in a ballerina doll, the rotating doll animates a ballerina, performing a pirouette.
The novel features of the invention are set forth with particularity in the appended claims. The invention will best be understood from the following description when read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to facilitate the explanation of the novel teaching of the invention, hereafter the various novel features will be described in conjunction with an animated doll, such as a ballerina doll which is operable to animate any one or a combination of ballet-type motions. However, as will become apparent to those familiar with the art, the various features may be incorporated in any toy in which similar motions are desired. Therefore, the description in conjunction with the ballerina doll should be regarded as one example, in which the teachings disclosed herein may be incorporated, rather than as a limitation thereof.
Attention is now directed to FIGS. 1 through 4, which are front, left side, and back cross-sectional views respectively, of one embodiment of the invention including a doll 10, having a torso 12 to which are connected a left arm 14, a right arm 15, a left leg 16 and a right leg 17. The doll further includes a head 20 supported above torso 12.
A pair of parallel linking bars 19 and 20 are pivotably supported at one end thereof at pivot points 21 and 22 respectively, by the torso 12. At the other end the bars lixedly support a position control plate 23 which forms part of a position control unit 24. At one end plate 23 supports arm 14 by means of a detent joint 25 so as to enable arm 14 to be swung to any desired position including the upward position, shown in FIG. 1.
Basically, the function of arm 14 is to control, as a function of upward or downward forces applied thereto, the vertical position of plate 23 relative to torso 12. The vertical position of plate 23 in turn affects the position of actuable means comprising a rotatable rod or shaft 28 through push rod 26 which is coupled to both.
Rod 28 carries a main gear 30, which is coupled to an output gear 32 (FIG. 3) connected to a shaft 33 of an energizable means comprising electrical motor 34, through a gear train, consisting of gears 35 and 36. Thus, when motor 34 is energized, the rotatable motion of the shaft thereof is transmitted through the gears to the rod 28. The latter, in addition to supporting gear 30, also supports at one end, gear 38 and at the other end gears 40 and 158. Housing 34a of motor 34 is xedly connected to the torso. The connection is designated by numeral 37 (see F IG. 3).
Briefly, when arm 14 and joint 25 are raised from a neutral position thereby raising plate 23, rod 26 and rotatable rod 28, gear 40 engages a face gear 42 supported on, and designed to drive a motion control means comprising crank assembly 44 whose function is to move legs 16 and 17 in small elliptical orbits, causing doll 10 to animate small steps, such as for example, pas de bourretype steps, performed by a ballerina. On the other hand, when the position control unit 24, rods 26 and 28 are in a downward selected position, gear 38 engages a gear 46 which is mounted at one end of a rotatable member or rod 48 which is rotatably mounted in the left leg 16. A friction cup 50 is coupled to the other end of rod 48.
When the doll is operated in the latter mentioned position or mode of operation, in which gears 38 and 46 are mechanically coupled, the function of cup 50 which is exposed through the bottom of leg 16 is to frictionally engage a stationary surface in order to inhibit the rotation of rod 48 and thereby function as a reaction member. Consequently, gear 30 supported on shaft 28 causes the latter to rotate when the motor is energized and thus the gear 38 and shaft 28 rotate around stationary gear 46. Since the axis of gear 28 is offset from the axis of shaft 48 and since shaft 28 rotates on a fixed axis in the torso 12, the latter is caused to rotate about the axis of shaft 48. At the same time the gear 158 on shaft 28 meshes with gear 157 on shaft 156 and the net effect is a reverse rotation of the shaft 156 to thus cause the latter to remain stationarily oriented with respect to an external observer. In other words, when the torso 12 is rotating as described, the shaft 156 does not rotate and the head spotting mechanism operates in the manner to be described. As as result, the housing 34a of motor 34 which is fxedly connected at 37 to torso 12, rotates about the axis of shaft 48, causing torso 12 to simultaneously rotate therewith. Thus, as long as gears 38 and 46 are mechanically coupled, and friction cup 50 is frictionally engaged to a stationary surface, the dolls entire body, rotates about an axis of rotation defined by a line extending between the cup 50 and the point on arm 14 at which a downward force is applied. During this rotation shaft 48 may nutate at its lower end.
The manner in which the crank assembly 44 causes the movement of legs 16 and 17 to animate a stepping motion, may best be explained by directing attention to FIG. l. Therein, the crank assembly 44 is shown including a crank shaft 52 with substantial parallel crank pins, or members 54 and 56, disposed 180 apart radially about the longitudinal axis of shaft 52. Shaft 52 is sup- 4 ported within the torso by a plurality of bearing blocks, generally designated by reference numeral 57.
A rod or bar 60 has one end thereof slidably supported in a sliding joint 62 and the other end pivotally mounted about pin 54 of the crank assembly 44. Leg 17 is carried by rod 60 by means of a detent joint unit 65. Thus, as shaft 52 of crank assembly 44 rotates, thereby causing pin 54 to rotate, rod 60 and leg 17 coupled thereto are caused to swing in small elliptical orbits which animate a stepping motion of leg 17.
Likewise, pin 56 of the crank assembly 44 pivotably supports one end of a rod or bar 70', whose other end is slidably mounted in a sliding joint 72. A detent joint 75 identical with detent joint 65 fastens leg 16 to rod 70. Consequently, when the latter pivots about pin 56 of crank assembly 44, the elliptical motion of rod is transmitted through the detent joint to leg 16 to cause it to animate a similar elliptical motion. Since the pins 54 and 56 on crank shaft 52 are disposed 180 apart with respect to shaft 52, the elliptical motions of the two legs are interrelated so that when one of the legs is down the other is up and when one of the legs points forward the other points backward to produce a highly realistic stepping motion.
From the foregoing it should thus be appreciated, that the animated motions which the doll is capable of performing, depend on the vertical position of shaft 28, and, in particular, the positions of gears 38 and 40k with respect to their associated gears 46 and 42, respectively. In the position of shaft 28 diagrammed in FIG. 1, in which neither of gears 40 and 38 is meshed, or mechanically coupled, to its respective gears 42 or 46 respectively, neither a stepping motion nor a rotational motion is produced. Therefore, the doll may be thought of as being in a neutral position. To cause the doll to animate the stepping motion, it is necessary to raise rod 28 in order to mechanically couple gear 40, supported thereon, with the face gear 42 which is supported by the crank shaft 52 of the crank assembly 44. In the particular embodiment, the raising of rod 26, which is coupled to plate 23 of the position control unit 214 is achieved by pulling upwardly on arm 14 which is connected to the plate 23 by detent joint 25.
The position control unit 24 includes a biasing arrangement, one function of which is to maintain the arm 14 in the pulled upward position and thereby cause the doll to produce the stepping motion until the arm is again purposely pushed downward thereby returning the doll to its neutral position. The position control unit 24 and the biasing arrangement incorporated therein may best be explained in conjunction with FIG. 4 and FIG. 5 to which reference is made herein. Therein, the unit 24 is shown including a first armature member which is pivotably supported on a pivot pin 82, assumed to be lixedly connected to the dolls torso. One end of the member 80 is also pivotably coupled to plate 23 by rod 84. The other end of member 81)l is connected to one end of a torsion spring 85 whose other end is xedly connected to the torso.
The function of spring 85 is to apply downward force on arm 80, so that once the arm 14 is pulled upwardly causing member 80 to rotate clockwise about rod 82, the downward force applied to member 80 by spring 85 is sufficient to maintain arm 14 in the upward position. Consequently, the doll continues to animate the stepping motion until the arm 14 is forced downwardly to the neutral position by a downward force which is sufficient to overcome the force applied by spring 85 to member 8i). The arrangement diagrammed in FIG. 5 represents the arm 14 in its pulled upward position, while the arrangement of the unit 24, shown in FIG. 4, represents the unit in the neutral position,
In the latter-mentioned position, a pin 86 which is xedly carried by member 80 is in engagement in a detent 88 of a second armature-like member' 90 of the unit 24. Member 90, which like member 80 is pivotably supported by pivot pin 82, ixedly supports one end of a spring 92, whose other end is connected to the torso. Brieiy stated, the function of member 90 and spring 92 coupled thereto is to control the force required to place the position control unit plate in the downward position so as to maintain the doll in the position in which the rotational motion of the doll lbody is produced.
As hereinbefore explained, the rotational motion of the doll is produced by engaging gears 38 and 46 (see FIG. l) as well as, by causing the friction cup 50 to be frictionally engaged with a stationary surface so as to inhibit the rotation of rod 48 and thereby, through the various gears and rod 28, the rotation of the motor shaft 33 (see FIG. 3), thus causing the housing 34a of motor 34 and the torso to which it is connected to rotate. The engagement of lgears 38 and 46 is accomplished by the lowering of rod 28 by means of push rod 26, which, as hereinbefore indicated is connected to plate 23 to which member 80 is also connected. Lowering of rod 26 is accomplished by pressing down on raised arm 14 so as to cause member 80 to pivot about rod `82 in a counter-clockwise direction with respect to its neutral position. The lowered position of member 80 and the other components of the position control unit 24 associated therewith are diagrammed in FIG. 6 to which reference is made herein.
When arm 14 is lowered and member 80' caused to rotate counter-clockwise about rod 82, pin 86 which, in the neutral position (FIG. 4) is in engagement with the detent 88 of member 90, causes the latter to also rotate about rod 82, in a counter-clockwise direction. Since spring 92 urges member 90 to rotate in a clockwise direction, it should be appreciated that the lowering of arm y14 and member 80 coupled thereto through plate 23l can only be accomplished by a force sufficient to overcome the torque applied by spring 92. The position control unit 24 is biased by spring 92 so that the initial force with which arm 14 must be lowered to overcome the tension of spring 92 is greatest when the arm 14 is rst forced downwardly from its neutral position. -Once the arm is moved downwardly from its neutral position, the magnitude of the force required to lower it so as to cause gears 38 and 46 to be mechanically engaged decreases greatly, in order not to overload bearings and cause the motor to stall.
Members 80 and 90 of the position control unit 24 are biased by spring 92, so that the arm 14 remains in the downward position in which the doll performs the rotational motion only as long as a suflicient downward force is applied to arm 14 to overcome the torque, provided by the spring `92. Once the downward force on arm 14 is removed, the spring 92 causes members 80 and 90 to rotate clockwise and return the plate '23 to the neutral position, thereby terminating the dolls rotation. Member 90 together with the strong spring 92 tends to produce a rm, clearly defined neutral position.
From the foregoing description it should thus be apparent, that in accordance with the teachings of the present invention, a doll is provided which is capable of animating two different types of motions. The doll incorporates an energizable motor which provides rotational motion to a rod 28 which is positionable to be in either a neutral, upward or downward position. The actual position of rod 28 is controlled by plate 23 of the position control unit 24 which is in turn controled by the application of forces to a raised dolls arm.
When `the arm and the position control unit 24 are in a neutral position, the gears mounted on rotatable rod 28 are in disengagement from their respective gears and consequently, the doll is motionless. By pulling upwardly on the raised arm, the position control unit 24 is biased upwardly raising rod 28 to provide engagement between one of its gears and a face gear coupled to a crank assembly, which through appropriate couplings activates the dolls legs to produce a stepping motion. Once biased upwardly to a produce the stepping motion, the position control unit remains in such a position until it is forceably returned to its neutral position.
The position control unit 24 is further operable to be biased downwardly so as to lower rod 28 and thereby couple -gear 38 mounted thereon to gear 46 on rod 48. The unit remains in the downward position, only as long as a suflicient downward force is applied. By pressing down on the arm and supporting the friction cup S0 on a stationary surface, cup 50 inhibits rod 48. Consequently, the motor housing coupled to the torso rotates thereby causing the entire doll body to rotate. The rotational motion is stopped by merely releasing the applicatin of a downward force on the arm thereby enabling the biasing arrangement of the position control unit to return the unit and shaft 28, coupled to plate 23 thereof by means of rod 36, to its neutral position, in which the doll is again motionless.
It should be pointed out that during the stepping or bourre motion the legs move alternately, up and down. However, for the performance of the rotational pirouette motion, the leg 16 with the friction cup 50 must be in a down position. Therefore in order to be able to switch from one position to another with maximum ilexibility, it is important that when the stepping motion terminates the left leg 16 is in the downward position.
To provide such a condition in both the neutral and downward positions of the position control unit 24, the doll of the present invention includes a disc-like member (see FIGS. l and 2), which is supported at one end of the crank shaft 52. Member 100 defines a radial slot 102 which points upwardly when pin S6 of the crank assembly 44 is down, at which time leg 16 of the doll is in the downward position, as diagrammed in FIG. l. The doll further includes a tang 104 which is connected to plate 23y of the position control unit 24 to point downwardly by a linking arm 106. When the doll is operable to animate the stepping motion, in which the position control unit is in the upward position, tang 104 clears member 100, thereby enabling it to rotate on the rotated crankshaft 52, which is part of the mechanism employed to produce the stepping motion.
However, whenever 'the dol-l is to be switched to either the neutral or the downward position, by biasing the position control unit 24 downwardly from the upward position, tang 104 is forced downward, engaging slot 102 of member 100. It should be stressed that the dolls stepping motion can be stopped only when the slot 102 points upwardly so that tang -104 may be engaged thereinto. Consequently, when the unit 24 returns to its neutral position from the upward or stepping motion position, slot 102 points upward, a position in which pin 56 and consequently leg 16 coupled thereto are in the downward state. Thus, leg 16 is down which permits the switching of the doll from the neutral position to the downward position to produce the animated rotational motion. Preferably, the peripheral edges of slot 102 are shaped to be quite sharp to insure that tang 104 engages slot 102 only when the latter points upwardly.
Herebefore, motor 34 (FIG. 3) has been assumed to provide the primary relative rotational motion between its housing 34a and its output shaft 33. In the stepping motion position, the shaft rotates transmitting rotational power to the Igears and rods with which it is coupled to finally move legs 116 and 17 so as to animate a stepping motion. The motor is preferably a DC electrical motor which energizable from an appropriate DC volta-ge source, such as one or more DC battery cells 100.
To increase the versatility of the doll, the motor is preferably a reversible DC motor which is capable of providing a rotational motion in either of two opposite directions or senses, as a function of the polarity of the voltage applied thereto. The motor 34 shown in the gures is assumed to be of this type. The novel doll of the present invention includes a novel arrangement for automatically reversing the connections between the battery cells and the motor each time the position control unit 24 is switched from its neutral position. Consequently, the doll is capable of animating the stepping motion in either a forward direction known in ballet as en avant or in a backward direction known as en arriere, as well as rotate either clockwisely or counter-clockwisely about its fixed axis of rotation.
The novel connections reversing mechanism may best be explained in conjunction with FIG. 4 wherein it is designated by numeral 110. The connections between various elements of mechanism 110 the motor 34 and the battery cells 100 are schematically diagrammed in FIG. 7 to which reference is made herein. Basically, mechanism 110 includes a sliding member 112 which is connected by a linking arm 114 to plate 23 of the position control unit 24 in order to move up or down in synchronism therewith. Thus, member 112 assumes any one of three positions, which include the neutral position, the up position when the doll is operated to animate the stepping motion or in the down position when a rotational motion is produced.
As diagramrned in FIG. 7, the member 112 is in the neutral position. The member 112 supports a pair of resilient blades 116 and 117 which are aligned in a vertical direction or axis. Mechanism 100 includes a pivot-pointdening rod 118 about which an armature-like member 120 is pivotably mounted. The longitudinal axis of the rod which is fixed to the torso 12 intersects, and is perpendicular to, the axis in which the blades 116 and 117 are aligned. Thus, the blades are aligned with the center of armaturelike member 120 which hereafter will be referred to as the armature 120.
The latter is shaped to define two rounded ring-like ends 121 and 122 and two triangular protuberances 125 and 126 on opposite sides of its center which is supported by rod or pivot point 118. The sides of the two protuberances 125 and 126 are designated by numerals 125:1, 125b, 12611 and 126b, respectively. Small ridges 127a, 127b, 128g and 128]) extend from the protuberances sides to define valley points 131, 132, 133 and 134.
The mechanism 110 further includes a fixed contact or plate 136 which is shown connected to the negative terminal of battery 100 which, as herebefore stated, may include one or more cells. Another fixed contact or plate 138 is connected to the positive terminal of the battery, through an ON-OFF switch 140. Two resilient electrically conductive, normally open (NO) contacts 141 and 142 are positioned adjacent contact 136, while an identical pair of contacts designated 143 and 144 are located adjacent contact 138. Contact 141 and 144 are connected to a terminal 34x of motor 34 while contacts 142 and 143 are connected to terminal 34y of motor 34.
The function of ends 121 and 122 of armature 120 is to bias a pair of contacts such as 141 and 143 to be in electrical contact with plates 136 and 138, respectively, when the armature assumes a first position (as shown), while urging contacts 142 and 144 to make contact with plates 136 and 138, respectively, when the armature is rotated counter-clockwise in which it assumes a second position. In the first armature position (as shown) terminal 34y of motor 34 is at a positive potential with respect to terminal 34x. The potential polarity is reversed when the armature is in its second position. Thus, by changing the armature position the polarity of the voltage which is supplied to motor is reversed resulting in a reversal of the sense of rotation of its output shaft.
The armature position is changed by the application of a torque to the armature by either of blades 116 and 117. As previously stated, the mechanism 110 as diagrammed in FIG. 7 is assumed to be in the neutral position. In this position neither blade 116 nor blade 117 is in contact with the armature 120.
Assuming that the position control unit 24 is switched to the downward position to produce the rotational niotion, member 112 which is coupled to plate 23 of unit 24 moves downward. As blade 116 engages side 125a, due to the resiliency of blade 116 it bends leftward finally engaging point 131. Thereafter, as the blade 116 continues to move downward a torque is applied to the armature at a point to the left of its pivot point, causing the armature to rotate counter-clockwise and thereby assume its second position. Similar switching to the second position from the diagrammed position may occur if member 112 were raised, causing blade 117 to engage the armature along side 12611 and point 134.
Once the armature switches to its second position, it remains in it even when the member 112 returns to its neutral position in which neither blade 116 nor blade 117 engages the armature. However, when the position control unit 24 is again switched from its neutral position to either the upward position or the downward position either blade 117 engages side 126a and point 133, or blade 116 engages side b and point 132 to cause the armature to rotate clockwise, back to its first position (as shown). Thus, the connection control mechanism may be thought of as an arrangement which includes a two-position armature which is rotatable between the two positions. A change in the armature position is produced each time the arrangement is switched from its neutral position to either one of two other positions, for example, the upward or downward position.
Herebefore, it has been assumed that when the position control unit 24 is in the downward position in which the dolls torso rotates, the rest of the body, including head 20, rotates as a single unit. Such an arrangement would animate the rotational motion of a person, such as a ballerina, whose entire body rotates together. However, in ballet, a ballerina typically rotates her body, often referred to as pirouetting, while attempting to maintain her head during each body revolution in a relatively fixed direction, hereafter referred to as head-spotting. This, the ballerina accomplishes by maintaining her head to face in a fixed direction, such as forward, while her body rotates a portion, such as half a turn. As she continues to rotate her body she snaps her head to catch up with her body and thereafter return the head to face forward, as the body continues to rotate. Consequently, she appears to face forward continuously, even though her body rotates.
To animate such a head-spotting feature in the preferred embodiment ofthe invention, diagrammed in FIGS. 1 and 4, the dolls head 20 is not fixedly connected to torso 12. Rather, it is supported in a head support block 150, which, together with other elements required to animate head-spotting, is shown in FIGS. 8 and 9 to which reference is made herein. Block which is shown to be cylindrically shaped defines an axial cavity 152 which is open at one end of block 150. A torsion spring 154 is axially positioned in cavity 152. One end of spring 154 is fixed to the block 150` and the other end is fixed to a cam 155 which is located adjacent the `blocks open end. As shown in FIG. 8 the cam 155 is fixedly connected to torso 12.
The head-spotting arrangement further includes spot holding means comprising a rod or shaft 156 which extends through both ends of block 150 and into the hollow torso 12. At its end in the torso, the shaft 156 supports a gear 157 (FIG. l) which is designed to mesh with a gear 158 (FIG. l) on rod 28 (FIG. l), when the latter is in the downward position. The top end of shaft 156 (FIGS. 1 and 8) fixedly supports a spot holder connecting means comprising a first element 161 of a two element brake unit. Element 161 has a radial extension 162, which is designed to engage an arm-like element 163. The latter represents the second element of the brake unit. Arm 163 is biased towards element 161 by a leaf spring 165.
The block 150 defines a longitudinal opening which accommodates a rod 168. Arm 163 is connected to one end of rod 168 while a cam follower 170, which is designed to follow cam 155 is connected to the other end of rod 168.
Before proceeding to describe how the elements shown in FIGS. 8 and 9 produce head-spotting it should be recalled that in the rotational mode of operation the shaft or rod 48 does not rotate, while gear 38 rolls around it and shaft 156 is, in effect, held stationary, against rotation, all as previously described.
As long as arm 163` does not engage extension 162 of element 161, as the cam rotates it also causes the rotation of block 150, which supports the head 20, through torsion spring 154. Consequently, the head, which may be assumed to be coupled to the torso through spring 154, rotates in substantial synchronism with the torso. However, once arm 163 engages extension 162, since arm 163 is coupled to the shaft 168 in block 150, the rotation of the block and the head mounted thereon is inhibited until the two (163v and 162) are somehow disengaged. Such disengagement occurs when the high point of the surface of cam 155 passes by cam follower 170 biasing the follower in an outward direction, opposite the biasing direction of leaf spring 165 (FIG. 9). Since the cam follower 170 and the arm 163 are fixedly connected to a common rod 168 when follower 170 swings outwardly arm 163 does the same, thereby disengaging itself from extension 162. As a result, the block 150 and the head 20 mounted thereon are free to rotate.
During the duration in which the block 150 is stationary and the cam 155 rotates compression or tension forces build up in the spring 154, depending on the sense of rotation of the cam. Once element 163, is disengaged from extension 162, namely, the brake is disengaged, the forces built up and stored in spring 154 are sufficient to cause the head to snap in the direction of rotation of the torso, catch up with it and thereafter complete the cycle of revolution therewith until the brake (elements 161, 162 and 163) is engaged once more, again stopping the rotation of the head.
The portion of each revolution during which the head is stationary while the torso rotates depends on the angles u and (FIG. 9) which are preferably equal so that the head is stationary for an equal portion of each revolution, regardless of the sense of rotation of the body. Each angle is defined =by the quiescent position of the cam follower 170 with respect to the edge of the high portion of the cam 155 in its quiescent or non-rotating position. As shown, ca -,82902 Thus, with such an arrangement the head is stationary for about 1/4 of each revolution.
It should be pointed out that the exact direction with respect to the vertical axis at which the head is stopped to produce the head-spotting effect depends on the direction of extension 162 about the longitudinal axis of shaft 156. However, irrespective of such a direction, once the doll is actuated in the downward position to produce rotational motion head-spotting would occur in the same direction, as long as the doll continues to rotate. Consequently, the direction may be regarded as a fixed preselected direction.
The foregoing description of the various embodiments of the invention may be summarized as comprising an animated toy which has a body such as body 12) which may be thought as including a first body portion (torso 12) and a second body portion (legs 16 and 17). The toy also includes a multi-position mechanism (unit 24) which is operable to be in either a first position (the upward position) or a second position (the downward position). The neutral position may be disregarded since in such a position the toys body is stationary. Motion control means (motor 34, the various gears, rods or shafts) are also included to transmit energy to the second body portion (such as the energy transferred by rods 6!) and '70 to legs 17 and 16, respectively), to move it (producing the stepping motion) with respect to the first body portion when the multi-position mechanism is in the first (upward) position. The motor control means also control both body portions to rotate together when the multiposition mechanism is in the second (down-ward) position.
The novel toy may also be thought of as having two body portions (the torso and limbs as one, and the head as the other) and actuatable means (motor 34, the gears,
rods or shafts) which cause one body portion (such as the torso and limbs) to rotate about a defined axis of rotation and spotting means (the assembly shown in FIG. 8) which causes the other body portion (head 20) to remain stationary or fixed in a selected direction during a part (such as of each revolution of the first body portion. The spotting means also include means (such as spring 154) which causes the head to return to the selected direction.
yIf desired, the norvel toy may be used by a playing child together with a base plate (not shown) from which a vertical support rod extends. The rod may fit into an appropriate base in cup 50. Such an arrangement may assist the child to balance the doll in a vertical position to perform the pirouette motion. Alsoif the plate were used in the burre motion the doll would tend to walk or step around the rod extending from the plate.
The term head-spotting has been used herebefore to refer to the feature of the in'vention in whicha do-lls head is maintained relatively stationary during a portion of a revolution of the dolls body, so that the head seems to point in a selected direction. Such a term is particularly applicable in connection `with a doll which includes a head portion. However, the term may be interpreted generically and defined as spot holding to refer to holding or maintaining one portion of a device such as a toy fixedly pointing at a selected spot or in a selected direction during a portion of a revolution of the rest of the toys body. The latter term, i.e. spot holding, will therefore be used hereafter in the appended claims, particularly in claims not limited to a doll.
Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art and, consequently, it is intended that the claims be interpreted to cofver such modifications and equivalents.
