Abstract
A children's activity and entertainment enclosure includes a housing a plurality of legs attached to the housing to support the housing at a selected elevation above a support surface and a flexible sheet material covering the housing and at least upper portions of the legs. A plurality of activity stations are present within the enclosure as are a seat for seating a child and a suspension mechanism for suspending the seat from the housing so that a child sitting in the seat with feet engaging the support surface can maneuver within the enclosure from one activity station to another.
Description
The present invention relates to a children's toy and more particularly to a play enclosure containing a movable seat for a small child which allows the child to move between a plurality of activity stations within the enclosure.
BACKGROUND OF THE INVENTION
There already exist a various play enclosures for small children. These run the gamut from a tent-like enclosure containing a multiplicity of balls to enclosed children's sandboxes and wading pools. These enclosures invariably have one or more openings to provide access to the enclosure. Thus, a child can enjoy the security of the enclosure without feeling isolated from other people in the vicinity of the enclosure. However, the same openings allow the child to leave the enclosure.
Children's walkers are also commonplace. A child sitting in one of these devices can propel him/herself along the floor in any direction. Therefore, a child using such a walker must be supervised at all times.
Another conventional child's activity toy is a swing, some of which are motorized so that a child can swing back and forth without any outside assistance. While the child on the swing requires minimal supervision, the child may become bored with this repetitive motion, particularly when there are no goals to be reached at the limits of that motion.
Accordingly, it would be desirable to be able to provide a single children's toy which has the advantages of a play enclosure, walker and swing without the aforesaid disadvantages.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a child's activity and entertainment enclosure which constrains a small child to some extent, yet allows the child to move in three dimensions between a plurality of different activity stations within the enclosure.
Another object of the invention is to provide a children's activity enclosure which allows the child to walk to different activity stations and play with toys there while still maintaining some control over the child's movements.
Yet another object of the invention is to provide a children's activity and entertainment enclosure which can be adjusted to accommodate children of different height.
A further object of the invention is to provide an enclosure such as this which can be stored and shipped in a knock-down condition.
A further object of the invention is to provide an enclosure of this type which can be assembled easily by the purchaser.
A further object of the invention is to provide a children's activity enclosure which is safe to use.
An additional object of the invention is to provide a children's activity and entertainment enclosure which is relatively inexpensive to manufacture in quantity.
Other objects will, in part, be obvious and will, in part, appear hereinafter.
The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the following detailed description, and the scope of the invention will be indicated in the claims.
Briefly, the children's activity and entertainment enclosure comprises a relatively large housing which is supported at an elevated position above the floor or ground by a plurality of long legs whose upper ends are rotatably secured to the housing at spaced apart locations around the housing. When the enclosure is in use, the legs extend out from the housing and down to the ground more or less like the legs of a spider. However, the legs can be swung together so that the unit has a relatively small foot print for ease of storage.
Rotatably mounted within the housing is a rotor having a shaft which extends down through an opening in the bottom wall of the housing. That bottom wall and the rotor define a circular track for an array of ball bearings positioned between the rotor and the housing bottom wall so that the rotor can rotate freely relative to the housing about a generally vertical axis. The rotor shaft supports the upper end of an L-shaped rotor arm whose lower end is offset laterally from the rotary axis of the rotor.
Resiliently suspended by way of a spring from the lower end of the rotor arm is an elongated hanger which supports a bag-type seat for containing a small child. As we shall see, the connection between the hanger and the seat allows for vertical as well as angular adjustment of the seat to accommodate different size children. That is, the seat may be adjusted so that a child sitting in a seat can touch the floor with his/her feet so that the child can bounce up and down and walk along the floor. Since the seat is supported by the rotor which is free to revolve within the housing, the child sitting in the seat can follow a more or less circular path within the legs of the enclosure.
Preferably, different toys are attached to the legs of the enclosure. These toys constitute activity stations or destinations to which the child can move by properly manipulating the seat. These stations thus constitute goals for the child which hold his/her interest, encourage mobility and improve the child's limb/eye coordination.
Preferably, the housing and the upper ends of the legs are covered by a canopy which tends to make the space within the legs more cozy without visually isolating the child sitting in the seat. Also, when the toy is placed outside, the canopy protects the child from the sun and sudden rain.
The various parts of the toy are simple metal and molded plastic parts which can be manufactured in quantity at a relatively low cost. Also, the parts are designed so that the entire enclosure can be sold in a knock-down condition so that the product can be shipped and stored in a minimum amount of space. Yet, when it comes time to assemble the enclosure, that can be accomplished relatively easily using only a screwdriver and a small wrench.

DETAILED DESCRIPTION OF AN ILLUSTRATIVE EMBODIMENT
Referring to
FIG. 1
of the drawings, the enclosure comprises a housing
12
supported above the ground or floor by a plurality, herein four, of identical long legs
14
. Movably suspended from housing
12
is a vertical hanger
16
which supports a seat
18
for containing a small child C. Preferably, a flexible canopy
22
covers housing
12
and the upper portions of legs
14
. The canopy is shaped and designed so as to shield the child C from the elements yet to provide ready access to the interior of the enclosure between the legs
14
. As shown in
FIG. 1
activity stations
24
a
to
24
d
are located at the different legs
14
at more or less the same elevation as seat
18
. These stations can contain various toys. As we shall see, the child C sitting in seat
18
, using a combination of leg and arm movements, can manipulate the seat and reach these stations which thus constitute play destinations which will hold the child's interest.
As will be apparent from
FIG. 1
, the child C is secure within the enclosure and protected from the elements, yet can still be observed by parents. Also, other children are free to walk in and out of the enclosure and interact with child C.
Referring now to
FIGS. 2 and 4
, housing
12
is comprised of a lower section
12
a
and an upper section or cover
12
b
. Section
12
a
is a molded plastic saucer-like part having a bottom wall
32
and upstanding sidewall
34
. Bottom wall
32
has a relatively large central opening
36
and encircling opening
36
is a groove or race
38
. The housing section
12
a
is formed with a multiplicity of upstanding intersecting walls
42
, many of which extend to sidewall
34
and all serve to rigidify section
12
a
. As shown in
FIG. 2
, a multiplicity of interiorly threaded screw-posts
44
are formed integrally with walls
42
at distributed locations between race
38
and sidewall
34
.
For attaching the legs
14
to the housing, a plurality, herein four, of slots
46
is provided in sidewall
34
and radially outer portions of bottom wall
32
. Slots
46
are distributed at equal angles about the circumference of section
12
a
, i.e., a 90° spacing. Also as best seen in
FIG. 2
, a notch
46
a
is provided in sidewall
34
adjacent each slot
46
for reasons that will become apparent.
As shown in
FIG. 2
, each slot
46
is bounded by vertical walls
42
and the wall
42
opposite each sidewall notch
46
a
contains the entrance to a leg support channel
48
which extends laterally from each slot
46
. In other words, there being four slots
46
, there are four leg support channels
48
spaced 90° around the axis of section
12
a
. Furthermore, the channels
48
on opposite sides of section
12
a
are parallel to one another. Thus, there are two pairs of parallel channels
48
, the pairs of channels being perpendicular to one another.
Referring to FIG. , each leg
14
comprises a shaped upper section
14
a
and a more or less straight lower section
14
b
. The upper end segment of each section
14
b
has a reduced diameter so that it can be telescoped into the lower end of leg section
14
a
as shown at the right side at FIG.
2
. Preferably, a conventional wire leg clip
52
is included at the joint between the two sections to prevent them from coming apart when the enclosure is being moved about.
Each upper leg section
14
a
comprises a relatively long main segment
54
a
and an upper segment
54
b
which is bent laterally at a right angle to segment
54
a
. Each leg section
14
also includes a relatively long lower end segment
54
c
which is bent at a right angle to main segment
54
a
but which also extends more or less perpendicular to segment
54
b
. Each leg section
14
a
is arranged to be attached to housing
12
by inserting the leg section
54
b
through a slot
46
in housing section
12
a
so that the corresponding leg segment
54
b
seats in the leg support channel
48
adjacent to that slot. Preferably, as shown in
FIG. 2
, the open upper end of each leg segment
54
b
is closed by a plug
56
and a coil compression spring
58
is inserted in each channel
48
between plug
56
and the closed end of the channel. The spring is under compression so that it tends to bias each leg segment
54
b
into the notch
46
a
adjacent to the slot
46
in which that leg section is placed. This helps to minimize unwanted relative movement between housing
12
and legs
14
when the toy is in use.
Still referring to
FIGS. 2 and 4
, housing
12
is designed to contain a rotor
62
having a tubular shaft
64
which extends down through the opening
36
in the housing bottom section
12
a
. Rotor
62
is formed with a radial flange
66
reinforced with a circular array of strut
68
which extend from the upper end of shaft
64
to the flange. Also, formed in the underside of flange
66
is a circular groove or race
72
which is the mirror-image of race
38
in housing bottom section
12
a
. When rotor
62
is seated in housing section
12
a
as shown in
FIG. 4
, the two races
38
and
72
form a track for a circular array of ball bearings
74
which separate the rotor from the housing section bottom wall
32
. Preferably, the ball bearings
74
are separated by small arcuate plastic spacers
76
(
FIG. 2
) to minimize the number of ball bearings required to enable rotor
62
to revolve freely within housing section
12
a.
As best seen in
FIG. 4
, a generally L-shaped rotor arm
78
is inserted up into the rotor shaft
64
and secured thereto by a bolt
82
which extends through aligned holes in the walls of shaft
64
and arm
78
. Bolt
82
is held in place by a nut
84
. When so secured, arm
78
can rotate freely relative to housing section
12
a
so that its lower or outer end sweeps out a circle around the axis of housing
12
a.
As shown in
FIG. 4
, legs
14
and rotor
62
are positively secured within housing section
12
a
by covering the open top of section
12
a
with the housing upper section
12
b
. Section
12
b
comprises an inverted saucer-shape part having a rounded top wall
88
and a short skirt or sidewall
92
. To facilitate centering housing section
12
b
on section
12
a
small tabs
92
a
(
FIG. 4
) extend from the outer surface of wall
92
so as to engage over the outer edge of housing section
12
a
. A small cylindrical boss
94
extends down from top wall
88
. When section
12
b
is seated on section
12
a
, that boss
94
extends into the open upper end of the rotor shaft
64
thereby journalling the upper end of that shaft. The underside of the top wall
88
is formed with semicylindrical leg support channels
96
which are more or less mirror-images of, and complement, the channels
48
in housing section
12
a
. Thus, when the housing section
12
b
is seated on section
12
a
, the various leg upper segments
54
b
are captured between the walls of corresponding channels
48
and
96
, but they are still free to rotate within the channels. Also, as with section
12
a
, housing section
12
b
is formed with intersecting vertical walls
98
which help to rigidify that section.
The two housing sections
12
a
and
12
b
are held together by a multiplicity of threaded fasteners
100
which extend down through holes
102
in cover section
12
b
and are screwed into the threaded posts
44
in housing section
12
a
. As seen from
FIG. 2
, the fasteners are distributed around the housing radially out from rotor
62
and there are fasteners on opposite sides of each channel pair
48
,
96
to capture the leg segment
54
b
seated in that channel pair. The leg segments
54
b
can all rotate within their respective channels
48
,
96
so that the legs
14
can be swung together when it becomes necessary to store the enclosure in small space.
Refer now to
FIGS. 3 and 4
which best illustrate the structure that suspends the hanger
16
and attached seat
18
depicted in
FIG. 1
from housing
12
. As shown in those figures, hanger
16
has an elongated more or less straight main segment
16
a
and an upper segment
16
b
extending at right angles to segment
16
a
. The flattened upper end of segment
16
b
is slightly upturned and connected to the lower end of a coil spring
110
whose lower end
110
a
is hooked through an eye
112
adjacent the upturned end of segment
16
b
. The upper end
110
b
of spring
110
is hooked to an eye bolt
114
secured to the lower or outer end of the rotor arm
78
by a nut
116
threaded onto the end of the eye bolt.
Mounted to the main section
16
a
of hanger
16
is a rack
118
. The rack is secured to the hanger by threaded fasteners
122
which extend through holes
124
in the rack and through aligned holes
126
in the opposite walls of hanger section
16
a
. The fasteners
122
are held in place by nuts
128
screwed onto the ends of fasteners
122
projecting through the hanger section
16
a
. As shown in
FIGS. 3 and 5
, rack
118
is formed with a vertical series of lateral slots or keepers
132
for reasons to be described later.
Preferably, a pleated flexible tube
134
or a tubular pad is provided to cover eye bolt
114
, spring
110
and hanger
16
above rack
118
.
Seat
18
is adjustably secured to rack
118
by a bracket assembly shown generally
133
in
FIGS. 4 and 5
. The bracket assembly
133
comprises a pair of more or less mirror image side plates
134
and
136
which bracket rack
118
. Each side plate
134
,
136
has upper and lower walls with notches
138
adjacent to one end of the side plate for accepting the adjacent sides of rack
118
and a small sector of hanger
16
so that the two side plates can be brought together from opposite sides of the rack. Also, each side plate
134
,
136
is provided with a raised post
142
having an axial holes
144
. When the two side plates brought together, the posts
142
and holes
144
therethrough are collinear so the two side plates can be clamped together by a threaded fastener
146
extending through holes
144
and held in place by a nut
148
screwed onto the exposed threaded end of fastener
146
.
However, before securing the two side plates
134
and
136
together, an adjustment button or latch
152
is installed between the two side plates opposite rack
118
. The adjustment button or latch
152
is basically a rocker arm having a pair of laterally spaced-apart ears
154
extending toward rack
118
. Aligned holes
155
are present in those ears. Also a tab
156
extends out from the lower end of button
152
more or less parallel to ears
154
and a lateral boss
158
extends in the same direction from the opposite or upper end of button
152
. Preferably, the portion of button
152
opposite boss
158
is raised or rounded as shown at
152
a
in
FIGS. 4 and 5
.
Before the two side plates
134
and
136
of bracket
133
are clamped together, one end of a coil spring
160
is engaged on the button boss
158
and the button is inserted between the two side plates so that the holes
155
in ears
154
are in alignment with holes
162
formed in the side plates. Then, a threaded fastener
164
is inserted through all of the holes
155
and
162
and held in place but a nut
166
(
FIG. 3
) threaded onto the exposed end of the fastener
164
. Thus, fastener
164
along with fastener
146
securely clamps the two side plates
134
and
136
together on opposite sides of rack
118
. Additional fastener
164
, nut
166
pairs may be used as shown in
FIG. 3
to further strengthen bracket
133
. However, the bracket
133
is slidable vertically along the rack
118
to adjust the height of seat
16
above the floor. The bracket is held in various positions of adjustment by the engagement of the button tab
156
in one of the slots or keepers
132
in rack
118
. As shown in
FIG. 5
, the button is biased by spring
160
so that the button tab
156
is urged toward rack
118
. Thus, when the bracket is positioned so that the tab is opposite one of the slots
132
, the tab will engage in that slot fixing the vertical position of the bracket relative to rack
118
. The bracket may be released simply by pushing on the button knob
152
a
which pivots the button in opposition to the bias of spring
160
so that the button tab
156
is withdrawn from slot
132
thereby allowing the bracket to be slid along the rack.
Referring to
FIGS. 3-5
, the seat
18
comprises a rigid molded plastic support ring
170
having an upwardly-outwardly extending ear
172
which is engaged between the bracket side plates
134
and
136
before those two side plates are secured together as described above. Ear
172
has a lateral passage
176
which may be aligned with passages
144
in the bracket side plates so that when the fastener
146
is inserted through the side plates and secured by nut
148
, it automatically pivotally connects the support ring ear
172
to the bracket. Thus, the support ring
170
may be oriented at different angles relative to hanger
16
by loosening fastener
146
. Preferably, the opposing surfaces of the side plates and ear are knurled as shown to prevent unwanted pivotal movement of the ring
170
when fastener
146
is tightened.
As shown in
FIGS. 3 and 4
, the seat support ring
170
supports a more or less conventional flexible bag seat
182
having leg openings
184
. The upper edge margin
182
a
of the bag seat
182
extends up within ring
170
and is looped around to the ring and suitably fastened to itself or to the ring by suitable snap fasteners or the like. Thus, the bag seat
182
is firmly secured to ring
170
. Yet it can be removed easily when necessary for cleaning, replacement, etc. Preferably, seat
18
includes a seat strap
190
(
FIG. 1
) attached to the ring
170
to hold the child C in the seat
182
.
Activity and entertainment stations
24
a
-
24
d
indicated in
FIG. 1
may contain any one of a number of toys. In the illustrated embodiment of the invention, the station
24
a
includes a vertical array of different-colored plastic blocks
192
pivotally mounted to leg
14
. The blocks have aligned vertical openings so that they can be slid onto leg
14
from the lower end of the leg and supported at a selected elevation on the leg by a pin or collar (not shown) engaged to the leg below the lowest block.
The illustrated activity station
24
b
includes a decorative mirror
194
with a padded frame clipped to leg
14
. The activity station
24
c
may be a tray
196
clipped to leg
14
and which may contain a variety of different objects (not shown) to amuse the child C. Station
24
d
may contain another toy.
It will be apparent from the foregoing that a child sitting in the seat
18
may move from one activity station
24
a
to
24
c
to the other by moving the seat along the circular path within legs
14
allowed by the rotation of rotor
62
. The connection of the seat
18
to the rotor allows the child to bounce up and down and swivel on spring
110
to achieve motion in three dimensions to optimize the child's enjoyment. Thus the child can proceed from one activity station to another so that the enclosure gives the child a maximum amount of freedom of movement while still confining the child to the enclosure.
It will thus be seen that the object set forth above among those made apparent from the preceding description are officially attained. Also, since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description as shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
