CHILD'S BATHING TOY
Abstract
The bathing toy includes a casing to be located on the inside
wall of a bathtub. The casing is supported by straps slung over the
tub wall and fastened to the outside wall by suction cups. Mounted
in the casing is a water pump, the nozzle of which can be rotated
to direct a stream of water from the pump for activating selected
water powered components. Bathtub water is drawn to the pump from
an intake tube immersed below the bathtub water level. With the
nozzle pointed in one direction, the water stream strikes a
carousel, rotating the carousel figures. The water drains from the
carousel to a teeter-totter bucket from which it is discharged into
the bathtub. If the nozzle is pointed in another direction, the
water stream actuates a turbine wheel and subsequently drains into
a bucketlike container seated within the casing. The container
includes a circular dish pivotally mounted on the bottom. The
circular dish and the container bottom have a plurality of holes
which are aligned when the dish is rotated to a certain position.
When the holes in the dish and the bucket bottom are in alignment
and the bucket is lifted out of the container, the water flows from
the bucket in tiny streams simulating a bathing shower. The pump is
so constructed that it has a protracted discharge period after each
actuating down stroke of its operating handle.

2. Description of the Prior Art
Many mothers have found that it is often a difficult task to induce
their children to enter a bathtub filled with water. One solution
to the problem is to provide bathtub toys which will attract the
child's attention and render the evening bath more enjoyable.
Some of the previously used bathtub toys were floating objects
while others were mountable on the bathtub. Of the bathtub toys
which were mountable on the bathtub. Of the bathtub toys which were
mountable on the bathtub, considerable difficulty has been
encountered in maintaining the toys in their proper position as the
soapy water within the tub usually splashed the toy and loosened
its mounting arrangement.
Furthermore, the previous bathtub toys were not customarily capable
of maintaining the child's sustained attention because they did not
provide sufficient amusement activity.
Additionally lacking the prior bathing toys was a provision for
utilizing a single hand operated power source capable of
selectively actuating any one or more of a plurality of action
components all included in a single toy.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The bathing toy is formed of a compartmentalized housing which is
mounted on the inside wall of a bathtub to amuse a young child and
induce him to bathe. The casing is suspended on the bathtub wall by
flexible straps which are secured to the outside wall of the
bathtub by suction cups. The central feature and motive means of
the toy is a hand operated pump which draws bathing water from the
tub and forces it from a nozzle. The jet of water from the nozzle
can be directed to various action components of the toy and cause
them to be activated. Among the water actuable components are a toy
carousel, a toy turbine wheel, a teeter-totter bucket and a water
shower bucket.
Referring now in detail to the drawings, the reference numeral 10
denotes a bathing toy constructed in accordance with and embodying
the invention. The toy includes a molded plastic housing 12 having
front 14 and rear 16 sections. The abutting common peripheries of
these sections are flanged and secured together by conventional
means such as an adhesive or heat seal.
To suspend the toy on the interior surface of the bathtub wall, two
flexible plastic straps 18 are provided. The straps are mounted on
the rear portion of the housing at opposite side edges thereof.
Conventional fastening means, e.g. adhesives, rivets or heat seals,
are used to secure the straps to the sides of the housing. A
suction cup 20 is secured adjacent the opposite end of each strap.
The rear surface of each suction cup includes a unitarily formed
mushroom headed protuberance 21 which facilitates the fastening of
the suction cup to the strap. The suction cup protuberance is
inserted through any selected one of a plurality of elongate
longitudinally spaced slits 22 adjacent the free end of each strap.
The mushroom head is forced through a selected slit so that each
suction cup is fastened in a manner similar to that of a button
which extends through a button hole.
To adjustably accommodate for various types of bathtubs wherein the
thicknesses of the bathtub walls differ, there is, as noted, more
than one slit in each strap so that the suction cup may be
adjustably positioned and, thus, the effective length of the strap
may be varied. This is important because the elevation of the
bathing toy above the level of the bathing water is critical to a
certain extent, i.e., a bathing water intake tube must extend into
the bathing water to permit the drawing of water by the pump.
To mount the toy, the suction cups are moistened and then are
attached to the exterior of the surface of the bathtub. The straps
extend over the top rim of the bathtub wall and downwardly along
the interior bathtub wall surface. The bathtub toy is thus
suspended from the outside surface of the bathtub wall.
With the suction cups positioned on the outside surface of the
bathtub wall, the soapy bathtub water which has a reduced surface
tension does not contact the suction cups and, therefore, the
suction cups will not easily come loose.
When the toy is mounted on the inside wall of the bathtub, the
child's attention will be directed to a pump 24 which activates and
powers the action components of the toy. The pump is mounted within
a central portion of the housing between the front and rear
sections and within a compartment of rectangular horizontal cross
section. The compartment is formed by abutting flanges 26 (see FIG.
4) extending rearwardly from the front section 14 and flanges 28
extending forwardly from the rear section 16.
The pump structure is shown in detail in FIGS. 2--6. It includes a
piston 28' supported by an open ended hollow vertical stem 30' (see
FIG. 3), both of which are stationary, and a cylinder 30 which
moves vertically relative to the piston. The piston is formed of
two resilient annular discs 29 mounted in abutting back-to-back
relation and secured in such position between spaced annular ledges
of a hub 29'. The hub is fastened to the stem adjacent and around
the open lower end thereof. Each disc has an outwardly flaring
tapered sealing flanged peripheral edge. The top of the stem is
supported, as soon will be seen, in a manner such that it can
experience rotation but no axial movement.
At the bottom of the cylinder 30 there is a central inlet opening
32 communicating with the bottom end of the stem 30'; a flexible
plastic intake hose 34, running into the tub water, is connected
thereto. Inwardly of the opening 32, a one-way (check) inlet
(inflow) valve 36 is positioned. This valve includes a flat
horizontal disc 38 which is free to move upwardly to a limited
extent away from its seat around the opening 32. Such movement is
restrained by a squat U-shaped cross member (cage) 40 which is
connected to the bottom of the cylinder and the bight of which is
elevated above the opening and extends diametrically thereacross.
When the cylinder is moved downwardly relative to the stationary
piston, a vacuum is created under the piston, opening the valve 36.
As a result, water is drawn up the tube 34, past the disc 38 and
into the cylinder 30 beneath the piston 28'. Once the cylinder
under the piston is filled, the disc will close by gravity to seal
the opening as the disc rests on its seat around the opening 32.
The disc prevents the flow of water in the reverse direction out of
the bottom of the cylinder.
A helical coil spring 44 is concentrically mounted about the piston
stem and is compressed between the top of the piston and the top of
the cylinder. The spring is further compressed when the cylinder is
moved downwardly. When the cylinder is released, the spring
releases its stored energy to urge the cylinder upwardly for a
protracted (sustained) discharge stroke. The open upper end of the
piston stem 30' is capped by one way outflow (discharge) check
valve 45 identical in structure to the valve 36. This valve opens
into a dome-shaped nozzle chamber 46 (see FIG. 2), the upper end of
which leads into a nozzle passage 48. The nozzle passage is located
within a hollow toy FIGURE 50 which may be of any amusing form,
e.g., a fish having the discharge end of the nozzle at the mouth
thereof.
A mounting plate 52 is fixed to the lower edge of the nozzle
chamber. The plate 52 includes a flat circular base having a
vertically upwardly directed stepped flange 54, which abuts the
side edges of the nozzle chamber and insures a water tight seal.
The bottom edge of the nozzle chamber is additionally sealed
against the upper surface of the mounting plate. The mounting plate
periphery extends beyond the flange 54 and is mounted for rotation
within a circular channel 56 in the top of the housing. The lower
surface of the mounting plate includes a concentric hollow tubular
projection 58 which tightly engages and is sealed against the
piston stem, thus preventing any leadage of water. The engagement
between the mounting plate and the upper and lower edges of the
circular channel prevent the stem from moving vertically.
As the cylinder is drawn downwardly, air within the cylinder above
the piston will exhaust through a clear space 42 between the
tubular projection (or the stem) and a central opening in the top
of the cylinder.
The manner in which the pump cylinder is mounted within the toy
housing and the linkage by which the cylinder is vertically
reciprocated are illustrated in FIGS. 2, 4, 5, and 7. Two flanges
60 (see FIG. 4) of L-shaped cross section project forwardly from
the pump cylinder 30. The front webs of said flanges 60 lie in a
common vertical plane. Elongate slots 62 are formed in these front
webs. To actuate the cylinder, a U-shaped pump lever 64 is
provided. The lever includes a tubular pump handle 66 and parallel
legs 67. The handle is mounted between spaced projecting bosses 67'
adjacent the forward end of each leg and the legs extend through
vertically elongate slots 68 in the front wall of the casing and
through the slots 62 of the L-shaped flanges. The opposite (rear)
end of each leg is pivotally secured to one of a pair of flanges
70, which project from the rear wall of the housing (see FIG. 5).
For this purpose each flange 70 includes a projecting lug 72. The
lugs 72 extend through circular openings adjacent the rear ends of
the legs to form the aforesaid pivotal mounting and lug heads are
subsequently flattened (see FIG. 4) to prevent inadvertent
disassembly.
When the pump handle is pulled downwardly, the legs 67 rotate about
the lugs 72 and the lower edge of each leg bears against the bottom
of each slot 62. The legs thus cause the cylinder 30 to move
downwardly. During this operation, bathtub water is drawn in
through the intake tube, past the inlet check valve 36 and into the
cylinder 30 below the piston 28'. Concurrently the spring 44 is
compressed.
When the handle is released, the spring forces the cylinder
upwardly causing the water trapped within the cylinder beneath the
piston (the valve 36 is closed) to flow through the piston stem.
The water flows through the outlet check valve 45 into the nozzle
chamber. The nozzle passage 48 is small enough to create a
considerable constriction to the free flow of water. Due to the
proportioning between the force exerted by the spring and the
diameter of the constriction, the spring will take in the
neighborhood of 10 to 12 seconds to fully discharge the water
collected within the cylinder. Thus, a child using the toy will not
be required to constantly move the pump handle in order to maintain
a steady flow of water. It will be noted that the child applies
force to the handle only on the downstroke thereof, the reaction to
this force creating tension in the flexible support straps. The
upstroke (discharge) of the pump is activated by the spring, not
upward manual force applied to the handle, which would not be
possible with a suspension mounting for the toy 10.
To stabilize the movement of the piston cylinder, the edges of the
L-shaped flanges are engaged in a track 76 formed in the surface of
the compartment walls. The track 76 is composed of a plurality of
horizontally disposed strips 78. The strips are preferably molded
in one piece with the flanges 26 and 28. Each strip extends across
the width of the compartment wall and includes a grooved portion 80
which is of a width slightly larger than the thickness of the front
face of the L-shaped flange. All of the grooved portions are
vertically aligned so that a track is thus provided and the
movement of the cylinder is thereby guided. The edges of the front
faces of the L-shpaed flanges ride up and down within the aligned
grooves when the cylinder is in motion.
The water jet from the pump nozzle passage may be directed in
either of two extreme positions, one of which is shown in FIG. 1
and the other in FIGS. 6 and 7. It should be noted that the
limitation of the rotational movement of the nozzle chamber 46 is
caused by a radial abutment stop 82 on the exterior of the chamber
(see FIG. 1) which projects above the mounting plate flange 54. The
abutment stop will limit the rotational movement of the nozzle
chamber and hence the nozzle FIGURE by contacting shoulders 84 and
86 which project above the circular channel 56 of the casing. Thus,
the nozzle chamber may rotate until the abutment stop contacts the
stops of the circular channel which are spaced apart approximately
180.degree.. With the nozzle oriented as indicated in FIGS. 1 and
2, the jet of water is directed to an activity turbine wheel which
is contained within the housing. The turbine wheel is formed of
front 88 and rear 90 half-wheels (see FIG. 2). Each of the
half-wheels is of one-piece molded plastic construction and
includes an outwardly tapering central hub 92 (see FIG. 10). A
keyed axle 94 is positioned so that its ends extend through the
central openings in the hubs to which it is fast. Each half-wheel
also has an annular flat vertical portion 96 and a thin outwardly
tapered vane ring 98 leading to a vertical outwardly offset annular
portion 100. Six equidistantly spaced turbine buckets (vanes) 102
are unitarily formed within each of the half-wheels. A portion of
each bucket projects beyond the interior of the associated
half-wheel in a direction parallel to the axis of rotation of the
wheel. The projecting portion is tapered to mate with and overlies
the tapered vane ring 98 of the opposed half-wheel. Alternating
buckets of the composite water wheel are a part of the same
half-wheel and the successive assembled buckets are spaced apart
half the distance of the buckets on the same half-wheel.
This structure greatly facilitates the formation of the half-wheels
by molding techniques and further facilitates assembly of the
composite turbine wheel. Once the two halves are brought together,
they are secured by conventional means, e.g. adhesive or heat
welds, at their abutting surfaces.
The central openings through the hubs 92 are square to accommodate
a square keyed section of the axle 94 so that the axle will rotate
with the turbine wheel. The axle is cylindrical adjacent its rear
end and is journaled within a cylindrical bore in a boss 103 which
projects from the rear wall of the housing. The rear end of the
axle includes an enlarged head 104. The axle is inserted through
the bore which also passes through the rear wall of the housing
with the axle head serving as a retaining member to prevent the
entire axle from slipping forwardly through the housing.
The front end of the axle projects through an opening in the front
wall of the housing. It should be noted that the cylindrical
diameter at the rear end of the axle and the bore through the rear
wall and boss are larger than the square section of the axle so
that the axle may freely be inserted into the housing.
To provide a further amusement function, a plastic disc 106 having
a suitable animatable design, such a multihued spirals as
illustrated in FIG. 1 is affixed to the cylindrical end of the axle
which projects through the front of the housing. This disc 106 is
formed with a concentric circular flange having a bore of a
diameter approximately equal to the diameter of the front end of
the axle. The flange is forced over said end of the axle and is
secured thereto by suitable means. A slight clearance remains
between the rear end of the flange and the front face of the
housing (see FIG. 10) so that when the turbine wheel rotates, the
disc 106 will rotate without interfering with the front of the
housing.
The water jet from the pump nozzle is directed as to strike the
turbine buckets at the top of the wheel and cause the turbine wheel
to rotate. The axle 94 rotates with the disc 106. A child will be
greatly amused by not only the pump which maintains a sustained
flow after release of the handle but also by the spinning turbine
wheel and disc. The churning action of the wheel on soapy water
also tends to form soap bubbles to the further delight of the
child.
In order to prevent excessive splashing of water, as the water
strikes the turbine buckets, a shield 108 (FIG. 1) is situated on
the upper surface of the housing and partially overlies the portion
of the wheel that projects above the housing, leaving a space for
the jet to impinge on the buckets. The water wheel is located in a
compartment (se FIG. 2) which is closed at its bottom by a
horizontal wall 110. The wall includes an opening 112 through which
the water drains from the turbine buckets.
The water which flows through the opening 112 runs into a bucket
113 which is removably seated on a shelf 116 formed by the lower
wall of the housing. The front wall of the housing is open to
permit access to the shelf and ready manual removal of the
bucket.
When the bucket is filled with water, a further play activity is
available for the child because the bucket includes a means whereby
it may simulate a shower. For this purpose, the bucket includes a
plurality of openings 118 (see FIG. 12) mutually arranged in an
orderly pattern, in the bottom surface thereof. The openings 118
are selectively blocked to prevent the water which is collected in
the bucket from draining therethrough. This is accomplished by
providing a shallow dish 120 within the bucket in abutting contact
with the bottom and a squat portion of the sidewalls. The dish 120
likewise includes a plurality of openings 122 arranged in the same
pattern and a projecting lug 124 for manipulation. The lug extends
through a slot 125 in the sidewall of the bucket; the ends of the
slot determine the extreme positions of the lug in one of which the
openings 118 are blocked. The slot is blocked to the passage of
water by the erect side of the dish. The dish is pivotally mounted
at its center on the bottom of the bucket by a rivet 126. In order
to unblock the openings 118, the lug is moved to one extreme
position in which the openings 122 of the disc are in alignment
with the openings 118 at the bottom of the bucket. This permits
water to descend from the bucket in a plurality of tiny streams
each of which is issuing from one of the openings 118 with the
entire effect simulating a bathing shower.
The nozzle may be rotated to a different position in which the jet
of water issuing therefrom is directed to another activity play
component, e.g., a carousel 130, as is illustrated in FIG. 7. The
carousel 130 includes a vertical shaft 132 which is journaled at
its lower end in a step bearing extending upwardly from the top of
the housing. The lower tip of the shaft is pointed to facilitate
rotation of the carousel by reducing friction between the shaft and
the bearing. A plurality of radial webs 134 extend from the shaft
and at their outer ends support vertical generally flat characters
136 that are substantially perpendicular to the webs. A carousel
roof 138 is mounted above the FIGS. and a dome shaped decorative
cap 140 is positioned atop the roof. The roof is supported by a
backsplash plate 144 which is in the shape of a mutilated cylinder.
The backsplash plate not only serves to support the roof but also
acts as a water splash guard, thus preventing excessive splashing
of water from the spinning characters. The upper end of the
carousel shaft is journaled within the roof and extends into the
cap.
As illustrated in FIG. 7, the water jet issuing from the nozzle may
be aimed so that it not only strikes successive individual FIGS.
136 but also strikes successive webs at points remote from the
shaft 132 thereby rapidly spinning the shaft and characters. The
nozzle cannot be turned far enough for the jet to be directed at
the carousel shaft to thereby immobilize the carousel.
The water which strikes the carousel drains through a plurality of
openings 146 formed in the top of the housing and into a storage
compartment 148 having a bottom wall formed by two horizontally
disposed flanges 150 and 152, which extend inwardly from the front
and rear walls, respectively, of the casing. The water drainage
from the carousel may thus be accumulated in the compartment and
stored to provide power for animation of a further activity play
component.
Such further activity play component which utilizes the stored
water is a teeter-totter bucket. The bucket is selectively fed
water through a valve 154.
The valve 154 includes a circular tunnel passageway 156 (see FIGS.
8 and 9) extending in a front-to-back direction through the front
wall 14 of the casing and leading into the water storage
compartment 148. The front wall is thickened in the region of the
passageway. The passageway serves as a valve body. A tubular valve
plug 160 rotates within the valve body with its inner open end
exposed to the water storage compartment. The outer end of the
valve plug is capped. The plug 160 has an outer diameter which is
approximately equal to that of the passageway. A radially extending
tab 162 projects from the inner end of the plug and rides against
the inner end of the thickened portion of the front wall to prevent
the withdrawal of the valve plug. A downwardly directed water
opening 164 located in the inwardly extending portion of the front
wall and communicates with the passageway. A radial orifice 166
extends through the valve plug 160 in the vertical plane of the
opening. The plug 160 may be rotated until the orifice is brought
into alignment with the opening 164 at which point water will flow
from the storage compartment through the valve plug and down the
aligned opening 164 and orifice 166. A handle 168 is attached to
the forward end of the valve plug 160 to provide a lever by which
the plug 160 may be rotated to vary the degree of alignement
between the opening 164 and thereby to regulate the rate of water
flow through the valve.
With the handle 168 in the off position, shown in FIG. 1, the
opening 164 and orifice 166 are not in alignment so that the water
in the storage compartment cannot flow through the valve. However,
the handle 168 may be turned to bring the opening and orifice into
partial alignment whereupon the water will flow through the valve.
In this position the water flow is less than the maximum. A maximum
water flow will be achieved when the handle is turned to the "fast"
position shown in FIG. 1 at which point the opening and orifice are
fully aligned.
A teeter-totter bucket 170 is mounted on an inset portion of the
front wall beneath the opening 164 of the valve. The teeter-totter
bucket includes two water receiving pockets 171 separated by a
dividing wall 172. The entire bucket is journaled on a horizontal
pin 174 having an enlarged head 176, the rear end of which is fixed
in an opening 178 in the front wall. Each of the pockets includes a
sloped lower wall 180, a rear wall 182 and a front wall 184. A
bucket stop member is provided to limit opposite rotating movements
of the water collecting bucket. The stop member is formed of a
central upward protrusion 186 on the rear wall 182 between the
pockets. The protrusion projects into an overhanging compartment
188 on the front wall. The compartment 188 has sidewalls 190 which
contact the stop member to limit the pivotal movement of the
bucket.
The bucket is in unstable equilibrium. The pivot pin is directly
beneath the opening of the valve 154 and water flowing from the
storage compartment will drop directly into either compartment of
the bucket depending upon the position of the bucket. In the
illustration shown in FIG. 1, the bucket is empty and is shown in a
central position wherein the flow of water will be deposited in
both buckets as the dividing wall 172 is in alignment with the
opening of the valve. The slightest imbalance in the amount of
water collected in either pocket will tilt the bucket in a
direction which will discharge the water from the pocket having the
greater amount of water. In the discharged position the lower wall
180 of the pocket will not be sloping upwardly as illustrated in
FIG. 1 but will be either horizontal or slightly downwardly
sloping. In such position drainage of water from the pocket will be
assured and furthermore, the opposite pocket will be in direct
alignment with the discharge opening of the valve. Said opposite
pocket, while unfilled and partially filled, will, with the
assistance of the support afforded by contact of the stop member
with a sidewall 190, be in stable equilibrium. With said opposite
pocket in alignment with the discharged opening, this other pocket
will fill with water until the weight of the water contained
therein becomes sufficient to overbalance the bucket and cause the
same to pivot in a direction which will discharge the water from
this opposite pocket.
It should be noted that the center of gravity of the entire
teeter-totter bucket is such that when both pockets are empty and
one of the pockets is in its water discharged position, the bucket
will tend to maintain such position. As the empty pocket which is
now filling with water accumulates a quantity of water the center
of gravity of the bucket will be shifted and when the water
accumulated is sufficient to shift the entire center of gravity to
the opposite side of the pivot pin, the bucket will pivot about the
pin and discharge the pocket which has just accumulated the water
and will position the other empty pocket beneath the valve
opening.
With the present invention, it can be seen that the bathing toy not
only provides multiple activity components, all of which sustain a
child's interest while bathing, but that all of the components are
coordinated with at least one other component so that a continuous
train of activity following the course of the flowing water will
ensue. Thus, the toy serves an educational function as well as an
amusement function.
In use the toy is mounted on the inside of the bathtub, as
previously described, with the intake tube 34 positioned below the
bathtub water level. When the child pulls down on the pump handle,
the pump cylinder fills with water beneath the piston and when the
handle is released, the compressed spring causes the water to
discharge from the cylinder through the hollow piston stem and
through the pump nozzle. This discharge, as previously noted, takes
a considerable period of time and the resulting flow of water from
the pump nozzle is in a sustained steady jet.
When the pump nozzle is aimed in one direction, the water jet
causes a turbine wheel to rapidly rotate and spin an optical
illusion design mounted on a disc which is secured to the turbine
axle. The discharge of water from the turbine is utilized to fill
the shower bucket so that the initial flow of water from the pump
serves two functions to wit: The rotation of the turbine and
illusion disc and the filling of the sublocated water collecting
bucket which when filled provides a shower toy.
With the nozzle pointed in the other direction, the flow of water
issuing therefrom impinges upon carousel characters and/or webs
(paddles) causing the carousel to rapidly rotate. The drainage of
this water fills a water storage compartment which is dischargeable
through a valve controlled by the child. The valve discharge is
further utilized to operate a sublocated teeter-totter bucket.
In whichever of the two positions the pump nozzle is directed, the
water finally returns to the bathtub. Thus, a minimal amount of
water splashing outside of the tub area is achieved.
In fact, the use of this toy will induce the child not to splash
water from the tub as his interest will be immediately centered
about the toy.
It thus will be seen that there is provided a child's bathing toy
which achieves the several objects of this invention and which is
well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above
invention and as various changes might be made in the embodiment
set forth, it is to be understood that all matter herein described
or shown in the accompanying drawings is to be interpreted as
illustrative and not in a limiting sense.
