Abstract
An amusement device including a rotatable container and a base
which base may be stationary, or upwardly concave or partly oval in
shape, or it may be in the form of an outer container. The
rotatable container has a central opening through which a shaft
extends from the base. Bearings are arranged between the container
and the shaft around which the container may be rotated and the
shaft is provided with a wheel by means of which a child or a group
of children in the rotatable container may exert a pulling or
pushing action to cause rotation of the container. The base may be
upwardly concave or partly oval in shape so that the device may be
utilized as a sled in which case it may have runners thereon or it
may provided with a hook or have projections secured thereto as by
welding to which a sled or snowmobile may be attached. Balls may
also be arranged between the base and a groove at the junction of
the side and bottom walls of the container to facilitate the
rotation of the container. Balls may also be arranged in a groove
at the periphery of the base member upon which the container rides
when the base is in the form of a container, or the base may be in
the form of a container having water therein and the shaft may be
secured to the outer wall of the container by a universal joint so
that the container may be rotated in planes inclined to the
vertical axis of the outer container to cause waves in the water in
the outer container. A track having upper and lower flanges may
also be secured to the shaft or to the base plate, some portions of
which are higher than other portions and a set of rollers secured
to the container may ride on the lower track so that the container
may rotate in an undulating manner to simulate a roller coaster. By
utilizing a planetary gear surrounding the shaft and providing spur
gears which meash with the planetary gear, the inner container may
be rotated directly by a child or a group of children seated in the
rotatable container.

Our improved amusement device may be constructed of various
materials, such as fibre glass, a metal, such as aluminum, or a
plastic material, such as a phenolic condensation product, and
generally includes as one of the elements a rotatable container. It
may, however, include an inner rotatable container and an outer
container which outer container may be rocked by a child or a group
of children in the inner container and which if desired may be
upwardly concave or partly oval in shape or it may have runners
thereon to provide a sled which runners may be formed integral with
or secured to the outer base plate or container in any desired
manner, such as by welding when the outer container is formed of a
metal or a suitable adhesive when the outer container is formed of
a plastic material. In another modification, the inner container is
both rotatable and movable from a horizontal to an inclined plane
or the inner container may be rotatable around a base supported
shaft and may be provided with means for producing a rocking
movement of the inner container which simulates a roller coaster,
or means may be provided within the inner container by means of
which it may be rotated by a child or a group of children setting
within the inner container.
In the following description, our invention will be exemplified by
a few specific examples which, however, are to be considered merely
as illustrative and not as limitations upon our invention.
As shown in FIGS. 1 and 2, our improved device includes an inner
container 1 and means are provided whereby a child or a group of
children placed in the inner container may rotate it. For this
purpose, an outer base or container 2 is provided having a flat
bottom wall and an upwardly and outwardly inclined arcuate side
wall and means are provided for rotatably supporting the inner
container within the outer base member or container. For this
purpose, a shaft 3 is provided, the lower portion of which is
secured to the inner wall of the outer container by suitable means.
As shown a flanged collar is provided, the flange portion 4 of
which is secured to the inner wall of the flat portion of the outer
base or container by suitable means, such as welding, and the
collar 5 of which surrounds the shaft to which it is secured by
suitable means, such as a set screw, and is in a position to
support the inner race of a ball bearing, the outer race of which
is provided with an annular flange on which one edge of the inner
container surrounding the bearing rests and which may be secured
thereto by suitable means, such as welding. The upper end portion
of the inner race of the bearings may be held in place by a collar
6 secured to the shaft as by a set screw 7, or if desired, the
inner race of the bearing may be fixed to the collar by suitable
means, such as welding.
To prevent small children from falling from the inner container,
the inner container extends a substantial distance above the outer
container and the upper portion of the shaft is provided with a
hand wheel 8 and the child or children within the inner container
may pull or push on the hand wheel at which time their bodily force
will cause rotation of the container.
To provide a more even rotation of the inner container, the shaft 3
may be provided with a shoulder 9 at a short distance below its
upper end portion on which the inner race of a second set of
bearings rest which may be secured to the shaft. The outer race of
the second set of bearings may be supported in place by a casing
10, the upper portion of which rests on a flange extending from the
outer race of the second set of bearings to which it is secured and
the lower portion of which casing has an annular flange 11 secured
to the bottom of the inner container.
A second form of our invention is shown in FIGS. 3 and 4 and
includes a rotatable container 12 and means for supporting the
rotatable container upon a base plate. For this purpose, a central
shaft 14 is provided which is fixed to the base plate 13 in any
desired manner. As illustrated, a flanged collar 15 is provided,
the flange of which is secured to the base plate 13 and the collar
of which surrounds and is fixed to the shaft 14 by suitable means,
such as a cotter pin 16.
To enable the container 12 to be rotated within the outer base
plate or container, the bottom wall of the container is provided
with an aperture through which the shaft extends with the outer
periphery of the aperture being spaced a short distance from the
shaft and an annular thrust bearing 17 is provided which rests upon
the bottom wall of the inner container and is held in place by a
collar 18 which as shown is secured to the shaft by a set screw. It
will be understood, however, that if desired, roller bearings may
be provided between the shaft and the bottom wall of the inner
container as shown in FIGS. 1 and 2 or as shown in FIGS. 18 to
20.
To facilitate the rotative movement of the inner container, an
annular arcuate-shaped indentation 19 may be formed at the junction
of the side and bottom walls of the container which rest upon a
plurality of spaced balls 20, four being shown, and each of which
in turn rests upon a multiplicity of smaller balls 21 as shown more
particularly in FIGS. 4 and 4A. The smaller balls 21 upon which
each of the larger balls rest, are held in place by an
arcuate-shaped housing 22 which terminates in a downwardly
extending flange 23 and a ball retaining means 24 is provided which
is spaced from but which is arranged in proximity to the upper
surface of each of the large balls and has an annular flange
secured to the inner wall 23 by suitable means, such as welding and
a flange secured to the base plate 18 by suitable means. For
holding the smaller balls in place in housing 22, an annular ring
25 extends inwardly from the ball retaining means 24 to which it
may be secured as by welding.
To enable a child or group of children to rotate the inner
container which as shown extends a substantial distance above the
base plate or outer container so that a child or group of children
will not fall therefrom, shaft 14 is provided with a hand wheel 26
secured thereto by suitable means, such as a set screw, and to
which wheel a pushing or pulling effect by a child or group of
children may be applied to cause the inner container to rotate.
By applying pressure to the different parts of the bottom portion
of the inner container, a rocking movement may also be applied to
the base plate which as shown may be upwardly concave or partly
oval shape and in upon which ribs or runners 27 may be formed
integral with or attached to the outer container so that the device
will slide downwardly over an inclined snow or ice-covered surface
or may be pulled over a snow or ice-covered level surface. For this
purpose, a hook 28 is provided to which a rope or strap may be
secured or by means of which the device may be secured to the rear
end of power-operated means, such as a snowmobile.
A third modification of our invention is shown in FIG. 5 to 9 and
includes an inner container 29 having its bottom portion arranged
within an outer container 30. A child or a group of children may be
placed in the inner container which extends a substantial distance
above the outer container to minimize the danger of a child falling
therefrom. In accordance with our invention, the inner container
may be rotated around a shaft 31 having a shoulder 32 on which
rests the inner race of a ball bearing which is held in place by a
collar 33 having a downwardly extending annular flange which
engages the inner wall of the inner container and the outer race of
the bearing is provided with an annular flange upon which an edge
of the inner container surrounding the bearing rests and to which
it may be secured by welding. If desired, the inner race of the
bearing may be welded directly to the shaft 31. A more stable
arrangement, however, is provided by the use of a collar 33 which
is secured to shaft 31 by suitable means, such as a set screw and
which has a downwardly extending flange which holds portions of the
inner container firmly against the annular flange of the outer race
of the bearing.
In accordance with the invention shown in FIGS. 5 to 9, the inner
container may not only be rotated by pushing or pulling on a hand
wheel 34 secured as by a set screw to the upper portion of shaft 31
to provide a rotation of the inner container in a plane concentric
with its vertical axis but may also be rotated in a plane which is
inclined to the vertical axis of the outer container when a greater
pressure is applied to one portion of the inner container than to
other portions. For this purpose, the shaft 31 is connected to the
outer container by a universal joint 35 which as shown includes a
clevis having its web portion 36 secured to the bottom wall of the
outer container and oppositely disposed arms, each having an
aperture therein through which pins 37 and 38, respectively, extend
into a central bar 39, the central bar 39 being arranged in a yoke
in the shaft around which the shaft may be tilted in a backward and
forward direction. A pin 40 also extends through the arms of the
yoke of the shaft with a press fit and through the central bar 39
with a slip fit so that the shaft may be tilted to the right or to
the left as shown in FIG. 6, or by using a combination of the
tilting means, the shaft may be inclined in any desired
direction.
In the device disclosed in FIGS. 5 to 9, the outer container may be
partly filled with water up to a level slightly above the bottom
portion of the inner container as indicated by the line 41 so that
when a greater amount of pressure is applied to different portions
of the inner container, the shaft may be tilted which in turn tilts
the inner container to thereby agitate the water in the outer
container to cause a wave-like effect.
The tilting movement of the shaft may be limited in various ways.
As shown, a housing 42 surrounds the shaft and has an upper opening
through which the shaft extends, the outer edge of which is spaced
a short distance from the shaft. Other means, however, may be
provided for limiting the tilting movement of the inner container.
For instance, the outer container may have an inwardly extending
annular flange 43 as shown in FIGS. 8 and 9.
Another modification of our invention is shown in FIGS. 10 to 12
which includes a rotatable container 44 and a stationary base plate
45. As illustrated in FIG. 11, a shaft 46 is secured, such as by
welding, to the base plate 45 which base plate as shown in FIG. 10
is circular in shape and to provide a convenient area within the
container for a child or a group of children, container 44 has an
annular seat 47 which terminates in a downwardly extending U-shaped
body portion 48 which forms an annular chamber for the legs of a
child or a group of children placed within the container and
occupying the seat 47.
In accordance with our invention, means are provided for rotating
the container by a child or a group of children seated within the
container and a bearing is provided which permits a swivelling or
undulating movement of the container as it is rotated. For this
purpose, the shaft 46 is provided with a shoulder 49 which as shown
is arranged slightly below seat 47 and upon which is arranged the
flat portion of a semispherical ball 50 which has an opening
therein through which shaft 46 extends. The curved portion of the
semispherical ball forms the inner race of the bearing and the
outer race 51 of the bearing is composed of a ring-shaped member
provided with upper and peripheral flat surfaces and which has an
annular groove formed on its inner surface for receiving the balls.
The outer race of the bearings is held in place by an upwardly
extending annular portion 52 of the body portion 48 which is
provided with an opening through which the shaft 46 extends. The
upper end portion of shaft 46 forms a support for a hand wheel 53
which is secured to the upper end portion of the shaft by suitable
means, such as a set screw 54, and which may be pushed or pulled by
a child or group of children occupying seat 47 of the inner
container to cause the inner container to rotate.
In this modification of our invention, means are provided to cause
an undulating movement of the container which simulates the
movement of a roller coaster as the container rotates around shaft
46. For this purpose, a plurality of rollers are secured to the
container which rollers during the rotation of the container engage
a stationary portion of the device, such as the base portion in
which case the track shown in FIG. 12 may be omitted, or they may
engage a track secured to the base or a track wound around the
shaft having an undulating outer surface to permit varying degrees
of undulations of the container as it rotates. As shown, the track
is arranged on the circular base plate surrounding the shaft and
consists of upper and lower flanges 55 and 56 which track at
intervals is held upwardly from the base plate by suitable means,
such as spacers or struts 57. The number of rollers may of course
be varied. As shown, two spaced rollers 58 are provided, each of
which is secured to the container in any suitable manner and each
of which rides on a flange of the track and causes an undulating
movement of the container resembling a roller coaster as the
container rotates. Each of the rollers may be secured to the
container by suitable means, such as plates, one end of each of
which plates is secured to the container by suitable means, such as
welding and the other end of which is secured to a roller which
rides on the lower or upper flange of the track as shown in FIG.
11.
Another modification of our invention is shown in FIGS. 13 to 17
which includes a rotatable inner container 60 and a stationary
member, such as an outer container or base member 61, and means are
provided for rotating the inner container 60 relative to the outer
container or base plate. For this purpose, a central shaft 62 is
provided which may be secured to the outer container in any
suitable manner, such as by welding, or as shown by a collar 63
which may be secured to the outer container by welding and which
forms a support for the shaft to which it is secured by a set screw
and for the inner race of a set of ball bearings, the upper portion
of which bearings is held in place by a boss 64 extending
downwardly from a central planetary gear 65. Boss 64 is secured to
shaft 62 in an desirable manner, such as by a set screw. For
providing a support for the inner container, the outer race of the
bearings is provided with an annular flange upon which the edge of
the inner container surrounding the bearings rests and to which it
is secured in any convenient manner, such as by welding.
To enable the inner container to be easily rotated relative to the
outer container, a plurality of rollers 66 may be secured to the
inner container at a short distance from its outer edge which
rollers ride on the outer container or base plate as the inner
container is rotated relative thereto. As shown more particularly
in FIGS. 14 and 16, each of the rollers is supported in place by a
web secured to the inner container which has a pair of downwardly
extending apertured flanges 67 through which a pintle 68 extends
which also passes through an aperture in the roller. The number of
rollers 66 may of course be varied depending upon the size of the
device. As shown four are provided.
To provide a place for a child or a group of children within the
inner container, a circular seat is provided which consists of an
angularly-shaped member having a level seat portion 69 and a
downwardly extending portion 70 with the extremities of both
portions being secured to the inner container and the downwardly
extending portion providing an annular recess into which a child or
a group of children may place their legs.
Means actuated by a child or group of children are also provided
for rotating the inner container relative to the outer container.
For this purpose, a plurality of spur gears 71 as disclosed more
particularly in FIGS. 15 and 17 are provided. The spur gears 71 and
the means for holding them in place are similar to each other and a
description of one with its associated appendages will suffice to
describe them all. As shown in FIGS. 15 and 17, a U-shaped member
72 is provided, the lower portion of which is secured to the inner
container, such as by welding, and the lower arm part of which
supports a socket 72a which may be secured thereto by welding and
has an inner lining 74 formed of a bearing material, such as
bronze, upon which a vertical shaft 71a bears. Shaft 71a extends
upwardly through a spur gear which gear has a boss 73 secured
thereto and to the shaft 71a by suitable means such as a set screw
and for holding the spur gear in the desired position. The shaft
71a also extends upwardly through a collar 74a which is secured to
shaft 71a by suitable means, such as a set screw prevents removal
of the shaft from the U-shaped member and then through a bushing 75
and terminates in an upper end portion to which a hand wheel 76 is
secured. Because the planetary gear is stationary, it will be
understood that as the spur gears are rotated, they will cause
rotation of the inner container. If desired, an over-running clutch
may be mounted within each of the spur gears so that all hand
wheels 76 and shafts do not rotate simultaneously.
Because the outer container or base plate is substantially concave
or partly oval in shape, it will be understood that as so far
described, the inner container may be rocked on the outer
container. Preferably, however, a pair of runners 77 are secured to
the outer container or base plate so that the device may be slid
downwardly on an inclined snow or ice-covered surface or may be
pulled over a snow or ice-covered level surface. For this purpose,
the outer container or base plate may be provided with a hook to
which a strap or rope may be applied for pulling the device or it
may be attached to a sled or snomobile.
Another form of our invention is shown in FIGS. 18 to 20 which
includes a rotatable container 78 and a stationary base member 79
which as shown is upwardly concave or partly oval in shape and to
the inner surface of which a stationary shaft 80 is secured by any
suitable means. As shown, a flanged collar is provided, the flange
portion 81 of which is secured to the inner face of the base
portion by suitable means, such as welding, and the collar 82 of
which surrounds the shaft and is secured thereto by suitable means,
such as welding, or as shown by a cotter pin 83 which extends
through apertures in the collar and the shaft.
The container is associated with the base member in a manner to
provide easy rotation thereof by a child or a group of children
placed in the container. For this purpose, the shaft is provided
with a shoulder 84 upon which rests the inner race of a set of ball
bearings which may be welded or otherwise secured to the shaft or
held in place by a collar 85 which is secured to the shaft by
means, such as a set screw. The outer race of the bearing is
provided with an annular flange upon which the edge portion of the
container surrounding an aperture through which the bearing extends
rests and to which it may be secured by suitable means, such as
welding. The shat 80 extends upwardly into the container and is
provided with a hand wheel 86 which may be held on the shaft by
suitable means, such as a set screw. To provide for easy movement
of the container 78, the outer base portion 79 is provided with a
grooved periphery 87 within which a comparatively large number of
spaced balls 88 are assembled.
In practice, a child or group of children may be placed in the
container and by pulling or pushing on the hand wheel, they will
cause the container to rotate and by applying their weight unevenly
upon different portions of the container, the child or children may
also cause a rocking movement of the base member 79.
Because of the upwardly concave or partly oval shape of the base
member 79, the device may be slid down a snow or ice-covered hill
or pulled over a level snow or ice-covered surface, or a sled or a
snowmobile may be fixed thereto. For such purpose, lugs 89 may be
secured to the device by suitable means, such as welding, to which
bars 90 may be secured by pins 91, which bars in turn may be
secured to apertured lugs 92 on the sled by pins 93. Similar
arrangements may be provided to connect the devices shown in FIGS.
3 and 4 and FIGS. 13 to 17, to a sled.
