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.

can be used, such as, for example, metal and wood.
FIG. 6
illustrates the operation of the gear assembly
118
and the bassinet
16
.
FIG. 7
illustrates the operation of gear assembly
118
and the swing
14
. The gear assembly
118
includes a worm gear
146
, the pivoting gear linkage
148
, the swing gear linkage
150
and the bassinet gear linkage
152
. The worm gear
146
is mounted onto a motor output shaft
154
and transfers the rotational movement of an output shaft
154
of the motor
102
to the pivoting gear linkage
148
. Alternative gearing and linkage arrangements are contemplated for transferring the rotational movement of the motor
102
to pivoting the gear linkage
148
. Pivoting the gear linkage
148
includes first and the second gears
156
,
158
concentrically mounted to one end of a first link
160
at a first pin
162
and a third gear
164
connected to an opposite end of the first link
160
. The first gear
156
is larger than the second gear
158
and operably engages the worm gear
146
. The second gear
158
rotates with the first gear
156
about the first pin
162
, and the second gear
158
operably engages the third gear
164
. The engagement and operation of the second and third gears
158
,
164
enables the first link
160
to pivot with respect to the first pin
162
between the space defined between the swing gear linkage
150
and the bassinet gear linkage
152
.
As shown in
FIG. 6
, in operation, when the motor
102
receives current is flow through the wire connection
98
under a first polarity, the output shaft
154
and the worm gear
146
rotate in a counter clockwise direction about a motor axis
166
, when viewing the worm gear
146
from the distal end toward motor
102
. The counter clockwise rotation of the worm gear
146
causes the first gear
156
to rotate in a clockwise direction about the first pin
162
, and causes the first link
160
to pivot from the swing gear linkage
150
toward the bassinet gear linkage
152
, until the third gear
164
engages a fourth gear
168
of the bassinet gear linkage
152
. Conversely, as shown in
FIG. 7
, in operation, when the motor
102
receives current flow through the wire connection
98
under a second polarity, the drive train rotates in an opposite direction.
The clockwise rotation of the worm gear
146
causes the first gear
156
to rotate in a counter clockwise direction about the first pin
162
, and causes the first link
160
to pivot from the bassinet gear linkage
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 pivoting gear feature can be employed to selectably and efficiently operate any two pieces of equipment connected to the outputs of a gear assembly.

of pivoting the gear linkage
148
to swing the output shaft
108
.
The bassinet gear linkage
152
includes the fourth, eighth and ninth gears

164
of pivoting the gear linkage
148
to the bassinet output shaft
110
. In alternative exemplary embodiments, other gear and linkage arrangements can be used to produce varied outputs of the output shafts

Referring to
FIG. 9
, a preferred embodiment of a circuit diagram for the control of the actuation device
22
is illustrated. The PCB
82
includes a circuit comprising a microprocessor
200
, or microcontroller, capable of synthesizing several different baby voices, baby-related sounds and music. An example of such a chip is the Winbond BandDirector™ microprocessor model number W561S15. Alternative microprocessors or microcontrollers can be used. The microcontroller
200
is actuated by the first and second switches
74
,
76
, and the pushbutton
70
. 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
128
is connected to: a first voltage input
208
of the microprocessor
200
through a resistor
209
; and a second voltage input
214
through the capacitors
216
,
218
. The positive end of the batteries
128
is connected to the sound transducer
72
. The sound transducer
72
then connects to the collector of a first transistor
212
through a resistor
211
. The base of the first transistor
212
is connected to a speaker connection
210
. The emitter of the first transistor
212
is connected to ground and to a speaker connection
210
through a resistor
220
. The positive end of the batteries
128
also connects to a first terminal point
222
. The first terminal point
222
connects to a second terminal point
224
. The terminal point
224
connects to a collector of a second transducer
226
. The emitter of the second transducer
226
connects to the one terminal of motor
102
. The base of the second transducer
226
connects to a collector of a third transducer
228
through the resistor
230
. The emitter of the third transducer
226
is connected to ground and to the opposite terminal of the motor
102
. The base of the third transducer
228
is connected to a motor input
232
through a resistor
234
.
When the microprocessor
200
outputs a sound signal through the speaker connection
210
, the sound signal is transmitted to the base of the transistor
212
enabling current to flow through the sound transducer
72
. The sound signal from the speaker connection
210
of the microprocessor
200
controls the sound transducer
72
causing it to produce baby-like sounds or music. When the switch
74
is actuated, the microprocessor
200
sends a signal to the sound transducer
72
to produce the music and sounds associated with the bassinet
16
. When the switch
76
is actuated, the microprocessor
200
sends a signal to the sound transducer
72
to produce the music and sounds associated with the swing
14
. When the first and second switches
74
,
76
are actuated, the microprocessor
200
sends a signal to the sound transducer
72
to produce the music and sounds associated with the seat member
18
. When the pushbutton
70
is depressed in conjunction with one or both of the first and second switches
74
,
76
, the microprocessor
200
sends a signal to the sound transducer
72
to produce the music or sounds associated with the bassinet
16
, the swing
14
or the seat member
18
, depending upon the location of the actuation device
22
. The microprocessor
200
includes a timer for controlling the length of sound segments of music, baby sounds, baby-related sounds and other desirable sound patterns and for controlling the length of operation of the bassinet
16
or the swing
14
following actuation.
The control system logic dictates the sounds and music produced by the sound transducer
72
as a result of the signal from the microprocessor
200
in response to the actuation of the first and second switches
74
,
76
and the pushbutton
70
. In a preferred embodiment, the microprocessor
200
can produce a signal to play six different songs and produce twelve different baby or baby-related sounds. In alternative exemplary embodiments, different types of sounds, different types of music and different total numbers of these sounds and music for different durations can be used.
