Abstract
A toy character having a body portion and a pair of legs operated by motor operated linkages that are controlled by a microprocessor. The microprocessor functions to move the legs in unison between sitting and standing positions or move the legs in opposite directions. The character thus functions to bounce and dance.
Description
BACKGROUND OF THE INVENTION
Toy figures have always been the mainstay of toys for young children. There exist figures that walk, crawl and speak in response to a child touching or squeezing various parts of the figure. There is a continual need for new and novel features, particularly, such as having the figure bounce and/or dance when activated.
SUMMARY OF THE INVENTION
There is herein described and illustrated a unique animated figure such as a toy tiger that can be programmed to repeatedly move between a standing and sitting position by moving the legs in unison up and down to effectively bounce. In addition to bouncing, the figure is designed so that the legs can be moved in alternate directions while the toy animated figure pivots about its tail to create the effect of a dancing figure.
To accomplish these movements of the toy figure there are provided motor operated assemblies controlled by a switch actuated microprocessor to provide for particular movements of the toy figure's legs. The legs are pivotally connected to the body portions of the figure. To bring about the bouncing action the legs are moved in unison repeatedly between sitting and standing positions. Specifically, a bi-directional motor driven gear assembly for one of the legs is activated, which leg is interconnected to the other leg by a rod so that when the driven leg is moved upward both legs are moved up in unison and when the motor reverses both legs are moved downward together. When this is repeated it results in a bouncing action for the toy figure. If it is desired to provide a dancing motion for the figure, the motor operated gear assemblies are operated to repeatedly move the legs in opposite directions relative to each other with the result that the figure pivots from side to side about its tail which gives the illusion of a dancing figure.
In order to effectuate a dancing motion of the figure, the center of the rod member interconnecting the two legs is held fixed at an intermediate location to create a pivot point with the result that the driving movement of the driven leg in one direction will result in the movement of the rod about the fixed pivot point to drive the other leg in the opposite direction relative to the driven leg. The figure is provided with a rigid tail portion that sits on the ground and when the legs are repeatedly moved in opposite directions relative to each other, the figure tilts from side to side about the tail portion to effectively create a dancing motion of the figure.
The details of the toy figure comprising applicant's invention is illustrated and described in detail but in order to better understand the function and interaction of the various components we provide the following general description.
The toy figure is provided with a bi-directional motor actuated gear mechanisms and linkages that are controlled by a battery operated, preprogrammed microprocessor that is signaled by a switch in an arm of the figure. Actuation of the microprocessor operates a motor to drive a gear mechanism to move the legs relative to the body portion. As aforementioned, when the motor is operated in one direction and then in a reverse direction the rod connecting the two legs is moved to move the legs up and down in unison about the body portion. Repeated bi-directional operation of the motor creates the bouncing action.
In order to move the legs in opposite directions to provide the dancing action a second motor operated mechanism is employed to effectuate a different movement of the rod interconnecting the legs. To this end the intermediate portion of the rod is restrained against movement in the vertical plane and secured in its horizontal position. The mid-point of the rod then functions as a pivot point about which the rod moves. Thus, when the driven leg is moved by its associated motor driven gear assembly the rod pivots about the restrained intermediate portion to move the other leg in the opposite direction. Suitable means are provided to limit the movement of the legs. Briefly, the second motor operated mechanism includes a gripping pawl assembly that when actuated the intermediate portion of the rod is held against a stop member to limit the rod to a pivotal movement about the restrained portion.
As an example, the operation of the aforementioned motor, gear and linkage assemblies are effected by a microprocessor to sequence the operation of the figure to give it initially a bouncing effect by repeatedly moving the legs upwardly to seat the figure and then downwardly to have it stand up. The microprocessor can then be sequenced to operate the second motor mechanism whereby the rod connecting the two legs is restrained in an intermediate position so the rod can only move in a horizontal path with the result that when one leg moves the other leg is moved in the opposite direction. Other mechanisms are provided to assist in the standing of the figure, provide a centering action of the rod and to assist in the moving of the legs in opposite directions and for emitting messages through a speaker when desired.
To have a better understanding of the invention reference is made to the following detailed description of the invention and embodiments thereof, from the claims and from the accompanying drawings in which:

DETAILED DESCRIPTION OF THE DRAWINGS
Referring first to
FIG. 1
there is shown a toy character
10
in the form of an animal such as a bear which has a plush fabric skin
12
disposed over a plastic case
14
. The toy character
10
includes a speaker
15
in case
14
and batteries
16
located in both its right
18
and left foot
20
, which batteries are used to supply power to a microprocessor
22
that is controlled by a momentary contact switch
24
located in left hand
25
. The right leg
26
and left leg
28
are pivotally connected to the body portion
30
of the character
10
in a conventional manner and are free to be moved relative thereto. The movement of the legs
26
,
28
are controlled by a gear drive mechanism operated by a bi-directional motor
32
. The drive mechanism between the motor and the left leg consists of a gear mechanism
34
in a gear box
35
which ultimately drives a gear
36
located on the shaft
38
that is suitably connected to the left leg
28
to move the left leg
28
in opposite directions as directed by the motor
32
. The legs
26
,
28
are connected by a rod assembly
40
disposed below the shaft
38
and depending on the operation of the rod assembly
40
the legs
26
,
28
will be moved in the same or in opposite directions relative to the body portion
30
. The rod assembly
40
connecting the two legs
26
,
28
for operating the legs in unison or in opposite directions consists of a rod
42
that has ball portions
44
,
46
located at their ends, which ball portions are secured into the right and left legs as shown. Connected to the mid-portion of the rod
42
is a ball member
48
, about which more will be explained hereinafter.
In the position shown in
FIG. 1
the rod
42
and the legs
26
,
28
connected thereto are free to move up and down in accordance with the rotation of the shaft
38
by the gear
36
. Specifically the shaft
38
pivots the left leg
28
in an upward direction, and the rod
42
is free to move the right leg
26
in unison with the left leg. The bi-directional motor
32
initially operates the gear mechanism
34
and drive shaft
38
to move the rod
42
and both the right and left legs upward to a sitting position and then the motor
32
reverses itself and moves the right and left legs in the reverse direction. When this repeated action occurs the body portion is moved up and down and the bouncing action is achieved as shown in
FIGS. 13A and 13B
.
When the microprocessor
22
functions to create the “dancing” action the legs are set to move in the opposite direction relative to each other. This results in the teetering of the character in one direction and then the other about the tail
52
as shown in
FIGS. 12A and 12B
. To move the legs in opposite directions the rod assembly
40
must have a different mode of operation. To this end there is provided a clamping mechanism to clamp the ball member
48
located at the center point of the rod
42
between a stop tab
54
and a midpoint retaining pawl assembly
56
as shown in FIG.
6
. The details of the pawl assembly
56
are shown in
FIGS. 5A and 5B
.
The clamping portion
58
of the pawl assembly
56
is moved to the lowered position as shown in
FIG. 5A
to secure the ball portion
48
of the rod assembly
40
in position. When the clamping portion
58
is moved upward, as shown in
FIG. 5B
, the rod assembly
40
along with both legs
26
,
28
are free to be moved in unison between sitting and standing positions.
As shown in
FIG. 5A
, the clamping and unclamping of the ball member
48
is accomplished by a second motor
59
which moves a cam gear assembly
60
to allow the pawl assembly
56
to be moved downwardly to retain the ball member
48
and associated rod
42
to form a pivot point
62
for the rod as shown in
FIGS. 6 and 8
. The pawl assembly
56
includes two relatively moveable members
64
,
66
. As illustrated in
FIG. 5A
, the bottom member
64
is biased downwardly into engagement with the ball member
48
to clamp the ball member
48
against the stop tab
54
(see
FIG. 6
) to create the pivot point
62
. The cam gear assembly is operated to move member
66
up. This raises member
66
to unlatch ball
48
. The pin
72
is limited in its downward movement by being located in slot
74
located in upper member
66
. The upper member
66
is limited in its downward movement by a pin
76
extending from plate
70
into slot
78
of member
66
. Operating on the upper pawl member
66
is the cam gear assembly that is moved by the motor
59
between the position shown in
FIG. 5A
wherein the pawl member
66
is in its lower position and the clamping portion
58
is in engagement with the ball element
48
and the position shown in
FIG. 5B
wherein the cam gear assembly
60
is located between the tabs
82
,
84
extending outwardly from plate
66
to raise the lower pawl member
64
against the biasing of spring
68
. This acts to disengage the pawl member
58
from the ball member
48
to free the rod
42
from being restrained at the pivot point
62
and allow the legs
26
,
28
to move in unison when shaft
38
is driven by the motor
32
. Referring again to
FIG. 6
there is a cross-section view with the legs broken away showing the position of the rod assembly
40
with the ball
48
retained in position between the stop tab
54
and the retaining pawl member
64
to form pivot
62
. Thus when the left leg
28
moves rearwardly the rod
42
will pivot in the horizontal plane about the ball pivot
62
to move the right leg
26
forwardly.
The movement of the legs in the forward and rearward positions are driven against a centering torsion spring
85
which is placed loosely on drive plate
90
which is driven by and rotates with drive shaft
38
. The movement of the legs
26
,
28
is restricted by the provision of a pin
86
extending from the right leg
26
into a slot
88
in the drive plate
90
. The active ends of centering torsion spring
85
are in contact with spring collar
94
on rod
42
and an arm
91
extending from the drive plate
90
. When the right leg
26
in
FIG. 6
is moved in a forward direction the collar
94
located on the rod
42
is moved against a free end of the torsion spring
85
until the pin
86
reaches the end of slot
88
as shown in FIG.
7
. The other end of the torsion spring
85
is held in position by arm
91
on plate
90
to increase the reactive force of the torsion spring
85
.
FIG. 8
shows the left leg moving forward. The torsion spring aids in reversing the action of the legs until they get to the neutra/centered position. As seen in
FIG. 9
the movement of leg
26
in the rearward direction is restricted by the pin
86
reaching the other end of slot
88
. Thus the “dancing” action is accomplished. This reversing action continues until the motor
32
stops and/or the microprocessor acts to reverse motor
59
to remove the retaining pawl from its clamping position.
FIG. 10
is a view taken along line
6
—
6
of
FIG. 1
with the legs
26
,
28
, rod
42
and centering torsion spring moved in unison in an arc from stop tab
54
around the rotational axis of drive shaft
38
.
When the legs are moved in unison to accomplish the bouncing action there is provided a spring assist assembly that includes a spring
96
and biased piston
98
that is engaged to help return the legs to their standing position. This is best shown in FIG.
2
and FIG.
3
. In
FIG. 2
the right leg is shown in the down position with the piston
98
and spring
96
fully extended. In
FIG. 3
the legs
26
,
28
have been raised to where the rod
42
moves the piston
98
up against the spring
96
that results in a compressive force that acts against the legs to assist in the downward action when the legs are moved downwardly by the reversing motor
32
to return the figure to the standing position.
It remains to note that the figure is provided with a standing switch
100
and a sitting switch
102
that responds to the relative position of the legs to the torso through a cam assembly
104
which feeds back such information to the microprocessor when the figure is in a particular position so the microprocessor will have the figure stand, sit, dance side to side and bounce up and down as preprogrammed.
There has been illustrated and described with respect to
FIGS. 1-11
a motorized mechanism for securing the ball
48
in position to bring about a pivoting action of the rod
42
and thus a dancing movement of the toy character
10
. In place of the motorized latching mechanism of
FIGS. 1-11
a non-motorized latching mechanism can be provided, several embodiments of which are shown in
FIGS. 14-16
. Essentially, the microprocessor is programmed so that when a dancing action is to occur an additional force is applied to the rod
42
to move the ball
48
into a latched position within the ball-shaped recesses formed by latch mechanisms
110
,
112
and
114
.
The latch mechanism
110
secured to gear box
35
includes a spring
115
biasing latch member
116
that is pivoted at
118
and when the ball
48
is biased against the latch member
116
it moves into recess
120
in rigid member
122
. After the ball
48
is in place it stays in recess
120
until it is pulled outwardly by a preprogrammed force acting on rod
42
to return the figure to a bouncing mode in which the legs will again move in unison.
Latch mechanism
112
is similar to latch mechanism
110
except that the latch member
124
is flexible and the flexibility thereof controls the movement of the ball
48
into and out of recess
126
.
Latch mechanism
114
is also similar to latch mechanism
110
but instead of the moving latch member
116
the latch mechanism is in two parts
128
,
130
. Upper part
128
is secured to gear box
35
and the lower moving part
130
is biased by spring
132
acting between a fixed member
134
and moving member
130
to provide the force controlling the movement of ball
48
like the spring
115
in FIG.
14
and the resiliency of the flexible member
124
in FIG.
15
.
