Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a child's toy that produces a musical output and a light display in response to activation by the child. More particularly, the invention is directed to a toy that can be converted from an infant's gym to a piano suitable for toddlers.




2. Background of the Invention




Children at different stages of development have widely varying physical capabilities and mental aptitudes. In order to entertain and stimulate children at different developmental stages, many different toys are needed, leading to increased expense and clutter. It is desired to provide a toy that is usable by a child over a range of years, and that continues to stimulate the child as he or she develops. Activity gyms have proven useful in this regard because they present different activities on a single toy that are tailored to different age groups. Many activity gyms also accommodate children of different height by allowing their display angle to be varied. However, known activity gyms have failed to provide activities of interest to children over a wide range of ages. A toy is needed that can entertain children of different ages with differing levels of physical and mental development.




SUMMARY OF THE INVENTION




The present invention provides a child's toy which is convertible between an infant's gym and a toddler's piano. In the infant configuration, a small child can be placed under or seated in front of the toy within reach of hanging shapes. When the infant moves the hanging shapes, a sensory output of music and lights is produced. The infant's gym can be converted into a toddler configuration, which has keys arranged on top, resembling a piano. A toddler standing in front of the piano can produce a sensory output of music and lights by pressing the keys. Therefore, the present invention provides a toy which stimulates and entertains children over a range of ages, sizes, and interests.




In a preferred embodiment, the toy has a substantially planar activity unit mounted on two supports. The activity unit has audio speakers and lighted keys to provide a sensory output when activated. Further, the activity unit and supports have interlocking elements which allow the activity unit to be moved between a vertical orientation and a horizontal orientation, corresponding to the infant's gym and toddler's piano, respectively. In the infant configuration, several shapes are suspended from the lower edge of the activity unit. Movement of the shapes initiates a sensory output of music and lights. In the toddler configuration, a sensory output is produced by pressing the keys on the activity unit. The sensory output is controlled by an output control unit located in the activity unit. A mode switch on the activity unit can be adjusted to vary the duration of the sensory output.




Numerous other objects and features of the invention should become apparent upon a reading of the following detailed description taken in conjunction with the accompanying drawings.

will be described with reference to each configuration of the toy


20


.




The activity unit


30


may be positioned on the support members


42


in a vertical orientation and a horizontal orientation, corresponding to an infant configuration and a toddler configuration, respectively. The activity unit


30


is secured in a given orientation through the engagement of interlocking elements


82


,


86


on the activity unit


30


and the support members


42


. A detailed view of the interlocking elements


82


,


86


is shown in FIG.


8


. First interlocking elements


82


are arranged at each end of the activity unit


30


. The first interlocking elements


82


have a four-sided hub


84


. Two adjacent sides of the hub


84


have a projection


84


A on an outer surface. The hub


84


also has a threaded opening


84


B in the center. Second interlocking elements


86


are arranged on an upper portion of the support members


42


. The second interlocking elements


86


have a housing with a four-sided recess


86


A for receiving the hub


84


. Three sides of the recess


86


A are formed with an indentation


86


B for receiving a hub projection


84


A. This arrangement of indentations


86


B allows the recess


86


A to receive the hub


84


in two different orientations. A captive screw


88


in the support member


42


is threaded into the opening


84


B to draw the interlocking elements


82


,


86


together and hold them in locked engagement.




In the infant configuration, the activity unit


30


is oriented vertically and several shapes


54


are suspended from the rocker bar, as shown in FIG.


1


. The toy


20


in this configuration can be used to entertain an infant lying underneath or a small child sitting in front of the toy. Although the keys


32


are active, the preferred way of producing a sensory output is by moving the hanging shapes


54


. The shapes


54


can be moved by a parent or by a child sitting in front of the toy. When the shapes


54


are moved, the rocker bar


50


is caused to pivot, which causes the cam


52


A to press on the leaf spring


38


, which in turn activates the rocker switch


36


. When the mode switch


70


is set on short play mode and the rocker switch


36


is activated, one song will play. While the song is playing, the keys


32


will light up in a random pattern. There are a number of songs stored in the control unit memory, each song having a unique light display associated with it. If the rocker switch


36


is activated additional times, the control unit


72


will cycle through the songs stored in memory, each time playing the next song and displaying its associated light pattern. In the long play mode, activation of the rocker switch


36


will result in ten minutes of continuous music. During the musical output, the control unit


72


will play the stored songs sequentially, and during each song, display the light pattern associated with the song that is playing.




Several steps are required to convert the toy


20


to the toddler configuration. First the hanging shapes


54


are removed from the rocker bar


50


and are placed on hooks


46


on the support members


42


, shown in FIG.


2


. Next, the rocker bar


50


is pivoted to the stowed position, taking the cam


52


A out of contact with the leaf spring


38


. The rocker bar is shown in the stowed position in

FIG. 5

, and in

FIG. 7

in broken lines. With the rocker bar


50


in the stowed position, the rocker switch


36


is effectively disabled. Next, the screws


88


are loosened, allowing the interlocking elements


82


,


86


to come out of engagement. The activity unit


30


is then rotated into a horizontal orientation. The interlocking elements


82


,


86


are engaged, and finally, the screws


88


are tightened to lock the activity unit


30


in position.




The toy


20


is shown in the toddler configuration in FIG.


2


. As shown, the activity unit


30


is oriented horizontally with keys


32


arranged on an upper surface. In the toddler configuration, the toy


20


can be used to entertain small children standing in front of the toy


20


and playing it, similar to a piano. Here, pressing the keys


32


is the preferred way of producing a sensory output. When a key


32


is pressed, the key switch


32


B beneath the key


32


is activated and an output is produced. In both the short play and long play output modes, a key


32


will light up when it is pressed. In the short play mode, when a key


32


is pressed, a single tone is produced. In the long play mode, when a key


32


is pressed, a segment of a song is played. If any key


32


is subsequently pressed, the next segment of the song will be played. The child user is therefore able to “compose” pieces of music using either discrete tones or segments of songs.




The effects button


60


, located above the keys


32


on the activity unit


30


, is active in both the infant and toddler configurations. The effects button


60


produces an audio output independently of the output mode setting. Pressing the effects button


60


will produce an audio output comprising one of several stored sound effects. If the effects button


60


is repeatedly pressed, the stored sound effects will be played sequentially.
