Description




FIELD OF THE INVENTION




The present invention relates generally to the field of toy activity centers. More particularly, the invention relates to a doll nursery center.




BACKGROUND OF THE INVENTION




Children enjoy playing with stuffed animals, dolls and figurines. Boys and girls alike often spend significant amounts of time playing with stuffed animals, dolls and figurines, and mimicking various human activities including eating, sleeping and playing. Children also enjoy role playing and, in particular, playing the role of a parent where the child pretends that the doll, stuffed animal or figurine is its baby. In many instances, a child will: prop a doll into a chair in order to pretend to feed the doll; lay a doll down in a make shift cradle and pretend to rock the doll to sleep; or place the doll in a swing or rocking chair and swing the doll. Children also enjoy singing lullabies or playing music to their dolls.




There are many known individual high chairs, individual bassinets and individual swings that are particularly adapted to accommodate a child's doll, stuffed animal or figurine and to facilitate the child's role playing. Such high chairs are supplied in numerous and varied shapes and sizes. Such bassinets and swings are typically manually operated and are distinctly separate devices.




Existing toy high chairs, toy bassinets and toy swings have a number of drawbacks. Each of these devices are typically designed as separate items requiring a parent or guardian who is seeking to obtain these toys for a child, to obtain three separate products. For many parents, purchasing three separate toys can be prohibitively expensive or burdensome. Further, each of these toys occupies a large amount of space and, for many households attempting to store three large toys of this type is very difficult. Additionally, because the toy high chairs, toy bassinets and toy swings are designed as inherently separate items, the probability of one or more of these toys becoming misplaced is very high in many households. Toy bassinets or toy swings typically are manually operated and require the child to repeatedly manipulate the bassinet or swing in order to achieve the desired rocking motion. Toy high chairs, bassinets or toy swings typically do not produce sounds, such as music.




Thus, there is a need for a doll nursery center that conveniently combines the features of a toy high chair, toy bassinet and a toy swing in a single toy, thus eliminating the need to purchase and store three separate toys. It would be advantageous to provide a single toy which includes the features of these three separate toys, takes up less storage space than the three individual toys collectively, and is less expensive to purchase than the three separate toys. What is needed, in part, is a toy bassinet and a toy swing which is configured to automatically rock or swing a child's doll, stuffed animal or figurine. It would be advantageous to provide a toy high chair, toy bassinet and a toy swing which is capable of producing sounds such as lullabies or baby sounds. It further would be advantageous to provide a doll nursery center which is fun, safe and easy to use for children.

152


toward the swing gear linkage


150


, until the third gear


164


engages a fifth gear


170


of the swing gear linkage


150


. The pivoting feature of pivoting the gear linkage


148


enables a single motor


102


to selectably operate the swing


14


and the bassinet


16


, thereby reducing the equipment required for, and the manufacturing costs of, producing the nursery


10

. The First and second switches


74


,


76


and the pushbutton


70


are connected to the trigger inputs


202


,


204


,


206


, respectively, such that when a switch or pushbutton triggers the associated trigger input, the microprocessor


200


generates and outputs a transducer controlling signal which corresponds to the switch, or combination of switches, chosen. The microprocessor


200


is powered by a power supply (batteries


128


.) The collective positive end of the batteries

72


. The sound signal from the speaker connection


210


of the microprocessor


200


controls the sound transducer


72
