' INVENTOR. BURT W ENSMANN BY ROBERT F. DAVIS CLAMORING DOLL FIELD OF THE INVENTION This invention relates generally to toys, and is particularly directed to an animated doll.

BACKGROUND OF THE INVENTION through the dolls shoulders. An example is seen in Dekan US. Pat. No. 3,436,859, in which a doll moves both arms up and down arcuately to perform a motion which imitates the splashing of water. This arm motion is accompanied by a nodding of the head. Both the head and arm movements are smoothly driven by crank mechanisms responsive to an electric motor.

The Dekan mechanism, and others known to the prior art, are too smooth and regular to be suitable for simulating this same type of arm motion as it would be performed in a completely different psychological context, specifically the arm motions of an impatient infant banging repeatedly upon a table. This is a gesture which suffering mothers recognize as a demand for immediate feeding. Such a petulant activity is best simulated by arm movements which are neither smooth nor regularly spaced. On the contrary, the actions should be sudden blows, irregularly spaced in time.

SUMMARY OF THE INVENTION In carrying out the present invention, a doll animation mechanism is provided in which the rotary output spindle of the animating motor has a plurality of radial teeth. The arms are rotatably mounted and connected to be driven by an angularly reciprocable yoke. A finger on the yoke is repeatedly engaged and displaced by consecutive teeth of the rotating spindle, and then abruptly released. At each release, the drive yoke and the arms are spring-returned. The spindle teeth are preferably irregularly spaced about the circumference of the spindle, so as to emphasize the frenetic nature of the activity by its irregularity in time.

BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 4 and 5 are exploded perspective view of a portion of the same mechanism.

FIGS. 6A through 98 are a series of action views illustrating an operating sequence of the same mechanism. The figures are labeled in such a way that drawings having the same numerical designation correspond in time.

Specifically, FIGS. 6A and 6B are fragmentary top plan and side elevational views respectively, correlated in time, and showing an initial phase in the operation of the mechanism, just prior to engagement of a driving tooth and driven tooth.

FIGS. 7A and 7B are correlated with each other in time, and are similar to FIGS. 6A and 63 respectively,

but show the position of the mechanism as tooth engagement occurs.

FIGS. 7C corresponds in time to FIGS. 7A and 7B, and is a side elevational view of one of the doll arms, illustrating how the arms rise arcuately during tooth engagement.

FIGS. 8 and 9A are similar to FIGS. 68 and 7B, but illustrate respectively the final phase of tooth engagement, and abrupt release after tooth engagement terminates.

FIG. 9B corresponds in time to FIG. 9A. It is similar to FIG. 7C, but shows the abrupt downward arcuate movement of the doll arm which occurs upon tooth release.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the animated doll 10 of this invention sitting in a toy feeding table 12 which is equipped with a food tray 14. The doll is molded of a rubber-like material, and includes a hollow torso 13, and a hollow head 11 and hollow arms 16 both of which are flexibly connected to the torso. The flexible connections permit a nodding motion of the head (arrows l5), and enables the arms 16 to be moveable arcuately up and down, as indicated by double-headed arrow 17, about an axis passing generally through the shoulders of the doll. A conventional spring motor 18 mounted within the torso 13 of the doll is wound by a pull-string 20 and ring 22.

During the spring run-out cycle thereof, the motor 18' Arm motions of this general type are not new in the animated doll art. What distinguishes the present doll animation, however, is their timing. Specifically, the arm motions of this doll include a relatively gradual rising are followed by a relatively abrupt falling arc, causing one or both of the dolls hands 26 to strike a sharp blow against the food tray 14, in imitation of the petulant, clamoring activity of a child who is impatient to be fed. The audible effect is enhanced if various metallic, and therefore noisy, objects such as a cup 28 or spoon 30 are held in the dolls hands 26 and are used in pounding upon the feeding tray 14. 7

FIGS. 2 and 3 show the animation mechanism 32 mounted atop the motor 18. To begin by describing it in general terms, this mechanism comprises a molded plastic frame 34 secured to motor 18 by a fastener 35 and having upstanding side walls 36 formed with bosses 38 upon which the arm actuators 24 are journaled to permit the reciprocal arcuate motion indicated by arrow 17 of FIG. 1. A molded plastic drive yoke 40 extends transversely across the platform 34, and is secured to and drivingly engaged with a drive train for the arm actuators 24 to impart the desired arcuate motion thereto. A return spring 41 is tensed between posts on the drive yoke 40 and a front wall 42 of the platform 34, in order to bias the yoke 40 in the direction which moves the arm actuators 24 arcuately downwardly.

The motor 18 drives a rotary output shaft 44 which extends upwardly from the motor through the floor of the platform 34, and terminates at its upper end in an eccentric headoanimating extension 46. A substantially circular spindle 48 is pressed upon the concentric lower portion of the output shaft 44, and rotates therewith. This spindle 48 is provided with radially extending driving teeth 50 (four of them in the illustrated example), which rotate with the spindle and repeatedly engage an integrally molded driven tooth 52 extending downwardly from yoke 40, to drive the yoke through an arcuate motion which results in upward travel of the arm actuators 24.

FIGS. 4 and show details of the connection between the yoke 40 and the arm actuators 24. Specifically, at both ends of the yoke 40 there are integrally molded claws 58 (see also FIG. 3) each comprising two opposed pawls 60 which engage two of several peripheral detents 62 formed in a gear-like molded plastic wheel 64 (see also FIG. 3). The engagement between the pawls 60 and the detents 62 serves to mount the yoke 40 in place, and also causes the yoke to rotate the gear wheels 64 about their axes.

Each arm actuator 24 terminates in an integrally molded disc 70 which is fastened by means of a rivet 72 to another disc 74 which is an integrally molded part of a carrier member 76 (see also FIG. 3). The carrier 76 is formed with an integrally molded stub shaft 78 that fits rotatably within a journal opening 80 formed in its cooperating boss 38 on the adjacent side wall 36 of platform 34.

An enlarged head 82 formed on the stub shaft 78 snaps through the journal opening 80 to retain the shaft in place therein, and is formed with recesses designed to make driving engagement with pins 84 molded integrally on, and projecting axially from, the gear wheel 64. The rotatability of stub shaft 78 relative to journal boss 38 permits the desired vertical arcuate motion of the arm actuators 24 to occur about the axis of shafts 78, and also permits an adjustment of the initial position of the doll arms by changing the angular position of the gear wheel 64 relative to its associated claw 58. During such adjustment, the toothed pawls 60 yield resiliently, and ride about the periphery of the gear wheel 64 to seat in different recesses 62. Thus, as desired, the dolls right arm can be set at a higher initial position than the left arm, as seen in FIG. 1, or both arms can be set at approximately the same height as shown by the positions of the actuators 24 in FIG. 2. This determines whether the doll will bang upon the food tray 14 with one or both hands 26, or the objects 28 and 30 contained therein.

In order to wind the spring motor 18, the pull-ring 22 is drawn outwardly from the body of the doll as indicated by arrow 90 in FIG. 3. When this happens, the motor output shaft 44 does not perform any reverse rotation, owing to the inherent declutching characteristics of the spring motor 18 during rewind. After the motor is wound and the ring 22 released, the string is pulled back into the motor 18 during the run-out cycle, as indicated by arrows 92 in FIGS. 6A and 7A. During this run-out cycle the direction of rotation of the output shaft 44 and spindle 48 is shown by arrows 94 in FIGS. 6A through 9A.

The first illustrated phase of the run-out cycle is represented by FIGS. 6A and 6B, which show one driving tooth 50.1 of the spindle 48 approaching the driven tooth 52 of yoke 40, but not yet engaged therewith. Thus, the driven tooth 52, yoke 40 and arms 16 are not yet displaced. The next phase of operation is illustrated by FIGS. 7A, 7B and 7C, wherein the closest driving tooth 50.1 has now engaged and partially displaced the driven tooth 52 as illustrated by arrow 96 of FIG. 7B. This results in an arcuate displacement of the yoke 40 about the axis of stub shafts 78, tensioning the return spring 41 and causing the claws 58 to rotate the gear wheels 64 and thus impart an upward arcuate displacement to both arm actuators 24 and arms 16. The arm displacement, which also occurs about the axis of shafts 78, is illustrated in FIGS. 7C and indicated there by arrow 98.

At a still further phase of the operation, illustrated by FIG. 8, the rotation of spindle 48 (arrow 94) has proceeded further, and the nearest driving tooth 50.1 has raised the driven tooth 52 still higher as indicated by arrow 96. The length of the driven tooth 52 depending from the yoke 40 is such, however, that once the mechanism passes the position of FIG. 8, the nearest driving tooth 50.1 must slip past the driven tooth 52, and thereby release it. The released condition is illustrated in FIG. 9A. There it is seen that although the spindle 48 continues to rotate in the direction indicated by arrow 94, the driven tooth 52 has now escaped from the driving tooth 50.1 which had previously engaged it, and the spring 41 has caused the yoke 40 and driven tooth 52 to return arcuately to' their original positions, as indicated by arrow 100. This is accompanied by a downward movement of the arm actuators 24 and arms 16, as indicated by arrow 102 in FIG. 9B.

The characteristic of the arcuate reciprocating motion of the arms 24 which lends itself to an interpretation as impatient clamoring arises from the fact that the rise of the arms 16 (arrow 98, FIG. 7C) is relatively prolonged and gradual, while the subsequent fall of the arms (arrow 102, FIG. 9B) is quite rapid and abrupt by contrast. This alternately gradual and abrupt motion is achieved in the mechanism of the present invention-by selecting the length of the driven tooth 52 so that each of the driving teeth 50 initially strikes the driven tooth somewhat above the lower end of the latter. Consequently, the driving teeth 50 must take a certain finite length of time to travel from the point of initial contact to the tip of the driven tooth 52, i.e., the maximum displacement illustrated in FIG. 8. During that finite span of time, the yoke 40 and arms 16 are displaced relatively gradually through their rising arcuate motions, against the bias of spring 41. But once the lower tip of the driven tooth 52 clears the driving tooth 50, the arms 16 are snapped downwardly rather rapidly and abruptly by sudden contraction of the spring 41. As a result, the downward motion of the arms is in the nature of a sudden blow. As such, it is particularly well adapted for simulating an impatient gesture, and for making a clamorous noise upon striking the food tray 14 in FIG. 1.

With reference once again to FIG. 9A, it is seen that after driving tooth 50.1 releases the driven tooth 52, as the rotation of spindle 48 (arrow 94) continues, the next consecutive driving tooth 50.2 moves into position to engage the driven tooth 52. It follows that there will be one complete cycle of upward and downward arcuate motion of the doll arms 16 each time one of the driving teeth 50 passes the driven tooth 52. Since there are, in this illustrative example, four driving teeth 50 spaced circumferentially about the spindle 48, there will be four cycles of up and down operation of the arms 16 for each full rotation of the spindle 48. Thus, even a single rotation of the spindle is sufficient to produce a multiple series of up and down clamoring arm gestures such as would effectively simulate repetitive, impatient banging of the dolls hands upon the food tray 14. Moreover, the run-out cycle of the spring motor 18 is such that, when fully wound, it is capable of producing several complete rotations of the spindle 48 during runout.

For accentuating the frenetic nature of the up and down arm motions, and thus emphasizing the impression of impatience, the animation mechanism 32 is designed to produce irregular time spacing between the successive blows delivered by the doll to the food tray 14. In order to accomplish this, the driving teeth 50 are irregularly spaced circumferentially about the spindle 48, as is clearly seen in FIGS. 3, 6A, and 7A. Thus, even for a substantially constant angular velocity of the spindle 48 during spring motor run-out, there is nevertheless a varying amount of time between consecutive engagements of the driving teeth 50.1 through 50.4 with the driven tooth 52. As a result, the doll 10 appears to pound upon the food tray 14 with a somewhat irregular rhythm, which heightens the impression of impatience.

During the entire time that the spring motor 18 is running out and the arms 16 are pounding upon the food tray 14, the eccentric extension 46 of motor output shaft 44, which is long enough to extend into the in terior of the dolls head 11 (see FIG. 1), executes a circular motion and thus causes the head to simulate a nodding motion (arrows 51). Head-nodding animation by means ofa flexible head-body connection and an eccentrically bent motor output shaft is not new in itself. See, for example, the US. patent application of Amici and Bornn, Ser. No. 842,156, filed July 16, 1969, and assigned to the same assignee as this application. In the specific context of a doll which also has a mechanism for simulating the impatient table-pounding motion described above, however, the head motions of the doll contribute to the overall frenetic body activity syndrome, which suggests a demand for immediate feedmg.

Thus it will now be appreciated that the animated doll of this invention performs arm motions which, by their abrupt and preferably arhythmic nature, and especially when combined with simultaneous head nodding, give an effective imitation of a child pounding upon a food tray to demand immediate feeding.
