Description
BACKGROUND OF THE INVENTION
The present invention relates to anthropomorphic dolls mimicking
the appearance of small children. More particularly, the invention
relates to such dolls capable of simulating the functions of liquid
ingestion and elimination and designed to serve as models for the
process generally known as toilet training.
In the art of constructing dolls for the delectation of small
children it has been known to provide for the possibility of
ingesting fluids, as from a nursing bottle, and also of permitting
the fluids thus ingested to escape from an orifice located in the
lower torso of the doll. Generally, however, no control was
exercisable on the duration of liquid retention by the doll and the
behavior of a trained child could not be reproduced.
It is, accordingly, a primary purpose of the instant invention to
teach the construction of a doll, and of an associated training
seat with integral chamber-pot, which is capable of receiving
liquids into a reservoir located internally to the doll through an
orifice within its mouth; upon placement of the doll into the
training seat the retained liquid draining into the
chamber-pot.
Another objection of the invention is to provide a doll
construction of relatively simple structure, which obviates the
need for complex mechanisms and other lever type of arrangements
commonly associated with prior art dolls which are more prone to
accidental discharges because of the nature of their structural
arrangements which have not been very effective in precluding
unintentional discharges of the liquid stored in the dolls
reservoir.
It is a further objection of the invention to teach the
construction of automatic valves operated by permanent magnets in,
or near, the training seat, suitable for use on the doll of the
invention.
It is yet another objective of the invention to describe such
details of construction and application as may make the doll and
seat of the instant invention into a readily marketable
combination, low in cost and of great reliability.
SUMMARY
The objectives of the invention are attained by the provision of a
hollow torso in a doll of otherwise arbitrary construction, the
insertion into that hollow torso of a reservoir connected by means
of flexible tubing to the mouth orifice, and incorporating a valve
actuatable by a permanent magnet on the outside of the torso and
permitting the fluid in the aforementioned reservoir to drain
through an orifice in the lower section of the torso.
Conjointly with the described above a training seat of suitable
proportions, and incorporating a chamber-pot, is also provided;
with a permanent magnet either rigidly or flexibly attached to the
seat in such a manner that upon the placement of the doll, in a
seated position, onto the chamber-pot the valve is brought within
actuating distance of the magnet. With the valve open, the
entrained liquid flows out of the reservoir in the doll's body and
into the chamber-pot.
The details of the preferred embodiment of the invention are
described below with reference to the accompanying
illustrations.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A preferred embodiment of the invention is illustrated in FIGS. 1
and 2. FIG. 1 shows a doll 100 and a training seat 200 in
perspective, with the location of a reservoir 110 and the location
of a chamber-pot 210 indicated. The doll 100 and the seat 200 are
separate assemblies and in the normal course of play would be kept
separated; the automatic valve of the invention being actuated upon
the placement of the doll 100 on the seat 200, as shown.
FIG. 2 shows the same doll 100 seated upon the training seat 200 in
a section taken along line 2--2 of FIG. 1. The doll 100 consists of
a torso 101 and a head 102 adjoined thereto, and is provided with
arms, legs and features to present a personable appearance; a mouth
103a is provided on the head 102 of the doll and surrounds an
orifice 103 which leads into a flexible conduit 104 terminating in
an enclosed volume 108 defined by reservoir shell 110 and lid 106.
A shorter section 105 of similiar conduit is also provided,
intruding into the space 108 through the lid 106 and terminating
internally to the doll torso 101. Both conduits are arranged with
their termini reaching the mid-point of the volume 108
approximately. All of the above enumerated components are suitably
made of plastic materials readily molded into the required shapes
and impervious to the passage of liquids. A valve assembly is
provided in the lower part of the reservoir 110, controlling the
flow of fluid between the volume 108 inside the reservoir 110 and
the volume internal to the torso 101 but external to the reservoir.
This valve includes a stem 122 upon which are mounted a retainer
123, a return-spring 124, and valve-cone 125 and an actuating mass
121, in that order. The stem 122 protrudes through an orifice 120,
provided with a chamfered face for the receipt of valve-cone 125,
and is so arranged that in the absence of actuating forces on the
mass 121, the return-spring 124, pressing on the retainer 123,
forces the valve-cone 125 into intimate contact with the edge of
the orifice 120. The actuating mass 121 is made from a material of
high magnetic permeability and is moveable by the attractive forces
exerted upon it by a permanent magnet 221 rigidly fixed in frame
201 of the seat 200.
In normal usage the doll is held and pampered by a child and may be
fed with a liquid, suitably water, from a bottle or nurser through
the orifice 103, the liquid thus ingested entering the space 108
through conduit 104 and displacing some of the entrapped air from
the reservoir through conduit 105, which serves as a vent. Escape
of the entrained liquid mass 109 from the reservoir 110 is
effectively prevented by the closed valve 120/125, by the tightly
fitting lid 106 -- the latter also serving to locate the reservoir
assembly rigidly in torso 101 through integral flange 107 -- and by
the arrangement of the conduits 104 and 105 which permit the doll
to be tilted and manipulated without the discharge of any
significant amount of liquid from the space 108.
When such discharge is desired, to simulate the eliminatory
processes of the human body, the doll is placed on the seat 200
with the lower end of the torso 101 abovethe chamber-pot 210; this
brings the permanent magnet 221, embedded in the frame of the seat
200, into close proximity of the actuating mass 121 within the
torso of the doll 100 and causes the latter to move in the
direction of the magnet 221, thus removing the valve-cone 125 from
contact with the orifice 120. The liquid mass 109 then flows, by
gravity into the internal volume of the torso 101 and is permitted
to escape therefrom via an orifice 111 perforating the lower
extremity of same.
Should the doll be removed from its position on the seat 200, the
attraction of the magnet 221 upon the mass 121 ceases instantly and
the valve recloses under the influence of spring 124, thereby
interrupting the discharge of liquid from the reservoir. To the
child playing with the doll, to whom the mechanisms recited above
are invisible and unknown, it thus appears that the doll is
`toilet-trained` and will not eliminate unless seated upon the
`potty`; providing both instruction and a sense of power. The child
feeds the doll and then, at its own chosen time, may cause it to
eliminate the liquid fed to it.
An alternate arrangement of the valve mechanism is illustrated in
the partial section of FIG. 4. A permanent magnet 231, embedded in
seat-frame 201, cooperates with a mass 131, susceptible to magnetic
influence, to cause valve-cone 135 to move out of engagement with
orifice 130. The normally closed relationship between elements 130
and 135 is maintained by a spring 134 acting on a lever 132, to
which the valve-cone 135 is attached at one end. The lever 132 is
pivoted near its midpoint on pivot 139 and contacts spring 134 at
its extremity furthest from orifice 130. The pivot 139 also serves
as the retainer for the spring 134.
Another embodiment of the invention, shown in FIG. 3, utilizes a
magnet 241, attached to belt 240, as the primary element of its
actuating mechanism. The magnet 241 acts on a mass 141 attached to
one end of a curved lever 142, pivoted at 149, carrying valve-cone
145 at the other end. The valve-cone 145 normally blocks an orifice
140 penetrating through reservoir shell 110 under the influence of
a spring 144 acting on retainer 143. Retainer 143 is pivotally
attached to lever 142 at 148, to prevent the transmission of side
forces which might bind the valve-cone 145 in orifice 140.
In this embodiment the discharge of liquid mass 109 from reservoir
110 is initiated, after the doll 100 is seated on the seat 200, by
girding the doll-torso 101 with belt 240 and securing the belt by
buckle 242, as illustrated in FIG. 5, thereby placing magnet 241 in
close proximity to the mass 141.
The above embodiments illustrate the general principles of the
invention and persons skilled in the art may, upon exposure to the
teachings of the disclosure, provide alternative mechanism in
detail without departing from the invention as defined in the
claims. For example, the reservoir may be arranged to be
pressurized in lieu of atmospheric pressure forcing the liquid out
of the reservoir.
