Description
BACKGROUND OF THE INVENTION
This invention relates to a swing case for a doll-like toy figure
and more particularly to a case including light-weight swing
possessing unusual stability when used to swing a toy figure with
pendulous motion.
Many toys are constructed of light-weight materials, such as
plastic and the like, which are selected for their damage resistant
properties as well as their economy of use and easy shaping
characteristics. Plastic, although a popular material of
construction making possible the fabrication of toys having sizes
and shapes previously considered unobtainable or impractical, often
possesses disadvantages in particular uses due to its extreme
light-weight and lack of stability compared to materials such as
wood and metal which result in heavier toys. However, any toy
structure intended for immobile play use while placed upright on a
surface must be sufficiently stable to remain in position for play
otherwise a child or other user becomes dissatisfied therewith and
loses interest therein, or, as is often the case, becomes
frustrated therewith and seeks to use the toy destructively in a
manner other than that for which it is intended. Stability is
especially required in immobile toys having moving parts such as
swings, trapezes, teeter-totters or the like, the pendulous or
oscillating motion of which will cause the entire toy to rock
to-and-fro and tip over if it is of insuffient weight or otherwise
of unsteady placement.
Toy cases or containers are often fabricated from sturdy long-life
materials, such as plastic, to increase their attractiveness and
the market appeal of the toy. After purchase the containers serve
little more than as storage boxes for the toy article therein and
thus represent a cost to the consumer which is not fully utilized
in terms of delivering maximum enjoyment and satisfaction for each
dollar spent on the toy and its container.
SUMMARY OF THE INVENTION
The present invention overcomes the disadvantages associated with
light-weight toys to be used when placed in an upright position by
incorporating in such toys a convenient form of counterbalance
which provides a more effective distribution of weight and assures
stability and freedom from tipping over while in use. Particularly,
this invention includes, on a frame member supporting a swing for a
doll-like toy figure, cover means which complement with the frame
to provide a complete enclosure for the swing yet which when open
serve as an effective stabilizing counterbalance and steadying
structure so that the doll-like figure can be moved on the swing
with pendulous motion without tipping over the frame. Moreover, the
frame, swing and cover means can be advantageously constructed of
light-weight material such as plastic and each having one piece
construction.
Therefore it is an object of this invention to provide a toy of
light-weight construction and exceptional stability when placed in
an upright position.
It is a further object of this invention to provide a doll-like toy
figure swing capable of placement on a table top or the like for
playing use having unusual stability by virtue of steadying means
capable of positioning either on the table surface or acting as
enclosures to form a container for the figure and swing.
This invention also ensures the maximum utilization of a toy
container by providing a toy container that effectively function as
a toy carrying case and is readily usable as a swing for a toy
doll-like figure. The container-carrying case has a stackability
feature which enhances its marketing appeal and display
characteristics.
Thus, an additional object of this invention is to provide a toy
swing for a doll-like figure which is conveniently conveyable in
its own carrying case and readily usable for playing with stability
without increase in weight due to addition of ballast or the
necessity of adding many and complex detachable parts and which
possess a stackability feature.
Other objects, features and advantages of the invention will be set
forth in and apparent from the following description of the
preferred embodiment of the invention considered together with the
accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 there is shown a swing carrying case 2 of the
type embodying the present invention. The carrying case 2 includes
a trapezoidal shaped frame member indicated generally at 4 to which
are securely attached pedestal legs 10. The pedestal legs 10 are so
shaped to enable the carrying case 2 to be placed on a flat surface
such as a floor or table top and remain upright without other
support. Also attached to the frame member 4 is a handle extension
14 having an opening 16 for ready placement of fingers for
transporting and conveying the carrying case conveniently. Also
shown in FIG. 1 are the carrying case enclosure covers 30 which are
identical except for orientation.
FIG. 2 shows, in a view similar to that of FIG. 1, the carrying
case 2 with the covers 30 in an open position revealing the case
contents, namely the swing 20 holding doll-like figure 100. The
covers 30, in the embodiment shown, are formed of a plane-like
surface sheet 32 having a rim or flange-like edge projection 34
extending about its periphery. This edge 34 provides a
complementary fit with the frame 4 when the covers 30 are in their
closed position. The covers are positionable either closed or open
through their connection to the frame 4 by the hinge indicated
generally at 40. The swing is mounted for pendulation within the
frame 4 by means of pivot pins 22 secured to the inside of the
frame 4.
As seen in FIGS. 1, 2 and 3, the frame member 4 includes side
support members 5, a base member 6 and a top member 7. The side
support member 4 have molded thereto, for increased structural
strength, reinforcing member 8, here shown to be T-shaped, which
connect with the pedestal legs 10 and continue about the periphery
of the handle 14. The opening 16 in the handle 14 is circumscribed
by a reinforcing flange 17. Also shown in FIG. 3 are U-shaped
channel inner legs 12 which are sized to receive, in tongue and
groove fashion, the handle 14 of another similar carrying case 2,
as illustrated in phantom in FIG. 4, for stacking, for display,
storage or other purposes. These inner legs 12 also serve to
provide a degree of increased strength and stability.
The cover 30 in FIG. 3 is shown cut away in portion to reveal the
swing 20 within the carrying case 2. The swing 20 is pivotably
attached to the inside of frame 4 by the pins 22 secured to the
frame side members 5 and the swing arms 24. The swing has a seat 26
and a back 28 as well as a circumferential member 27 for
maintaining a doll-like figure securely in position after placement
in the seat 26.
The swing 20, the covers 30 and the trapezoidal frame member 4 are
preferably each individually formed in one piece from polyethylene,
polypropylene, polyvinyl chloride, (PVC)
acrylonitrile-butadiene-styrene (ABS) or other suitable plastic
material used in the manufacture of toys. Thus these parts are all
light-weight and easy to carry, strong and breakage-resistant as
well as attractive. Moreover these materials of construction are
convenient to form and completely safe for children. Therefore,
this swing and its carrying case may comprise only four parts, the
swing 20, the frame member 4, and the two enclosure covers 30, thus
minimizing production costs as well as complexities of assembly and
use by the child.
Also shown in FIGS. 3 and 4, is the manner in which the cover 30 is
held in the closed position to form a container for the swing. The
peripheral edge 34 of the cover 30 has a raised lip 38 at its edge
extremity. This lip 38 cooperates with a similar lip 9 on the top
member 7 of the frame 4 in a latch-like manner to maintain the
cover in closed position complementary against the frame 4.
The hinge assembly is shown in detailed top view in FIG. 5 and in
side cross-section in FIG. 3. The peripheral edge 34 of the cover
30 has U-shaped portions cut out to leave remaining a tongue 42.
The base 6 has hingeable tab-like members 44 depending from it,
seen in cross-section in FIG. 4, each of which has two raised
projections 46 with undercut portions seen at 48 which form a
groove into which the peripheral edge portion of cover 30 securely
fits. In assembly, the raised projections 46 slide to the U-shaped
opening of the peripheral edge 34 with the peripheral edge 34
fitting in the undercut groove portion 48 of the raised projections
46. The arrangement may be made further interlocking by known means
if desired.
The operation of the toy swing is illustrated in FIG. 6 showing the
frame 4 containing the swing 20 with enclosure covers 30 open to
the position where they contact the surface on which the pedestal
legs 10 rest to maintain the toy in an upright position. In this
side view, FIG. 6, the swing is shown moving back and forth in an
arc lying in the plane of the drawing and substantially parallel to
the side member 5 with pendulous motion in a right-left direction
when viewing the drawing. When the swing 20 reaches the end of its
motion at either extremity of the arc the centrifugal force and the
swing's momentum cause a substantial force to be exerted on pivot
pin 22 in a direction along the swing arm 24 towards the swing seat
26. This force in turn will cause the frame 4 to pivot about a
fulcrum point which can be considered located along the center line
of the frame side member 5 in the vicinity of the base 6, pedestal
legs 10 and inner legs 12.
With sufficient length of arc and magnitude of momentum from the
back and forth swinging, the force on the pin 22, which is
dependant in part upon the weight of swing 20 and its contents such
as a doll 100, could be great enough to cause the frame 4 to
oscillate and eventually tip over because of its light-weight were
it not for the covers 30. The covers 30 function as counterbalances
absorbing some of the energy arising from the oscillations of the
base occurring during pendulation of the swing since forces are
transmitted from the base 6 through the hinge means 40 to the cover
30 and partially dissipated there with the result that the swing
and frame remain substantially upright and steady. The combined
outrigger and counterbalance effect of the enclosure covers 30
enable the frame 4 to oscillate without tipping over or, depending
on the degree of forces generated, to remain fixed and immobile
entirely without oscillating, then significantly increasing the
toy's stability. Yet, since the covers 30 are fabricated from
light-weight material the overall weight of the toy is not greatly
increased and it remains conveniently conveyable.
When a child desires to no longer play with the swing, he or she
may close the covers 30 with the doll 100 remaining in the swing 20
and easily covey it to another location by means of the handle 14.
If a household has two or more of such toys, as is often the case,
they may be conveniently stored with a minimum of space by stacking
one upon the other in a closet or on a shelf or table top. Thus,
maximum sufficient use of the entire assembly is obtained to the
satisfaction of the manufacturer, retailer and consumer.
