Abstract:
A musical toy consisting of a plurality of separately operated dolls each having a flexible bellows provided with an air chamber having an outlet, and a passageway connecting the opening of the bellows and the air chamber, the air chamber and passageway of each of the dolls being of a size to produce a pre-determined musical note, and wherein each of the dolls is also provided with indicia designating the note.

Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     The present invention relates generally to musical toys, and particularly to a train within which there are located a plurality of musical &#34;dolls,&#34; each of which is constructed to produce a selected sound of the musical scale. As the head of each doll is depressed by the child, the musical sound or note associated with that particular doll is emitted. The individual dolls may be color-coded to correspond to color-coded sheet music, and may bear the indicia &#34;do,&#34; &#34;re,&#34; &#34;mi,&#34; etc. Moreover, the dolls may be arranged within the train in their musical sequence, although it is apparent that the dolls may be removed from the train and played with independently thereof.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The musical toy of the present invention is illustrated generally in FIG. 1 wherein it will be apparent that a plurality of musical dolls 10 are positioned within openings 12 provided within a toy locomotive 14 and cars 16. The dolls are provided with the indicia &#34;do,&#34; &#34;re,&#34; &#34;mi,&#34; &#34;fa,&#34; &#34;so,&#34; &#34;la,&#34; &#34;ti,&#34;and &#34;do.&#34; The operation of the musical dolls 10 in relationship to the above noted indicia and the color-coded sheet music 18 will be explained hereinafter. 
     Turning now to FIGS. 2-4, it will be apparent that each of the dolls 10 is provided with a head 20 which is provided at the top thereof with an opening 22 and an internal downwardly depending cylindrical wall 24. A flexible, hollow bellows mechanism 26 is provided at the top thereof with a knob 28 which may be pressed upwardly through the opening 22, as illustrated in FIG. 3, to secure the bellows 26 to the head 20 at which time the cylindrical wall 30 of the bellows 26 is supported by the cylindrical wall 24 of the head 20. The bellows 26 terminates downwardly in a circular flange 32 which extends outwardly from the neck 34 such that the bellows 26 is secured to the upper housing 36 by urging the circular flange 32 through the opening 38 located in the top of the upper housing 36 at which time the circular flange 32 is located immediately below the opening 38, as illustrated in FIG. 3. The upper housing 36 is provided with a window 40. As will be further apparent from FIG. 4, the cylindrical side wall 42 of the upper housing 36 is complimentary in configuration with respect to the cylindrical wall 44 of the lower housing 46. Within the cylindrical wall 44 of the lower housing 46 there is also provided a window 48. Thus, when the upper and lower housings 36 and 46 are assembled, as illustrated in FIG. 2, a part of the window 48 of the lower housing 46 remains exposed. Interposed between the upper and lower housings 36 and 46, respectively, is a sound disc or diaphram 50 which is provided with a cavity 52. It will be apparent from FIG. 3 that when the components are assembled, the opening in the bellows 26 at the bottom of the circular flange 32 is in communication with the cavity 52 of the disc 50. Moreover, there is provided within the disc 50 a narrow slit designated by the reference numeral 53 which passes through the wall 54 of the disc 50 into the cavity 52. The lower housing 46 is hollow thus defining an air chamber or cavity 56. Thus, air leaving the bellows 26, after compression thereof, is forced outwardly through the opening defined by the circular flange 32 into the cavity 52 of the disc 50 and thus downwardly through the slit 53 into the relatively large cavity or air chamber 56 within the lower housing 46 and eventually outwardly through the window 48. Depending from the lower housing 46 is a base designated by reference numeral 57. 
     The sounds emitted from the dolls 10 depend upon the size of the air chambers 56 defined by the cylindrical wall 44 of the lower housing 46 and the size of the slit 53. More specifically, the larger the capacity of the air chamber 56 and the slit 53 the lower the pitch of the sound. Sounds ranging from the lower &#34;do&#34; to the upper &#34;do&#34; are obtained by the arrangements illustrated in FIGS. 5-27 wherein it will be apparent that the underneath side of each of the diaphrams 50, as illustrated in FIGS. 6, 9, 12, 15, 18, 21, 24, and 27 is provided with a ridge 58 that is complimentary to the configuration of the top of the cylindrical wall 44 of the lower housing 46 such that the ridge 58 abuts the internal wall surface of the cylindrical wall 44. With reference to FIGS. 6 and 7, for example, the ridge 58 of the diaphram 50 is designed to fit along the inside of the generally cylindrical wall 44 in such manner as to define an air chamber 56 which consists of the entirety of the cavity defined by the cylindrical wall 44. But where the size of the air chamber 56 must be smaller in dimension, to achieve a higher pitch, such as illustrated in FIGS. 9 and 10, for example, the ridge 58 is provided with a straight section 60 which extends across the diaphram 50 so as to divide the area of same into two parts. The straight section 60 of the ridge 58 (FIG. 9) is thus complimentary in configuration to the partition 62 which is provided across the cylindrical wall 44 of the lower housing 46, as illustrated in FIG. 10, dividing the area defined by the cylindrical wall 44 into two paths. Thus, as the diaphram 50 is fitted in place over the cylindrical wall 44 the volume of the cavity or air chamber 56 is reduced. The same is true with respect to the different diaphrams and lower housing structures illustrated in the remaining figures. By adjusting the position of the straight sections 60 of the ridges 58 of the diaphrams 50 to coincide with the positions of the partitions 62 of the lower housings 46 it is apparent that the effective area of the air chambers 56 is varied. Turning now to FIGS. 21, 24, and 27 it will be apparent that to achieve even smaller air chambers 56 the diaphrams 50 are provided with ridges 58 consisting entirely of straight sections 63 defining small rectangles which are complimentary in configuration to the vertical walls 64 formed within the cylindrical walls 44 of the lower housings 46. In a manner similar to that described above, the diaphrams 50 are fitted on top of the cylindrical walls 44 such that the rectangular shaped ridges 58 fit within the top portions of the rectangular shaped partition walls 64. 
     From the foregoing, it will be apparent that a variety of amusement functions may be performed with the musical toy of the present invention. It is possible for the child to load the loco 14 and cars 16 with the music dolls 10 and play with the so-assembled train. A child of a very young age will derive amusement from merely pulling the loco and on occasion depressing the heads 20 of selected of the dolls 10 to produce sounds at random. The dolls 10 may be arranged in the fashion illustrated in FIG. 1 with their &#34;do,&#34; &#34;re,&#34; etc. indicia in order of sound and the child may experiment with playing various tunes. With the sheet music instruction 18, which includes notes 66 and 68, for example, which are color-coded to correspond with the heads 20 of the dolls 10 that produce the corresponding note of the music scale, it is possible for the child to &#34;read&#34; music from the sheet 18 by depressing the appropriate color-coded head 20 to play different songs.
