Description
FIELD OF THE INVENTION
The invention resides in the field of a safety seat for infants that is floatable and therefore useful for infants in any circumstance near water.
SUMMARY OF THE INVENTION
A broad object of the invention is to provide a safety seat of the general character referred to, which is floatable in water, and which returns to an upright position in the water if it should fall into the water in any other position.
Another broad object is to provide a floatable infant safety seat that is effective for holding an infant therein, in safety condition, such as by a harness, but that is also effective for holding an infant in other circumstances not related to a water environment.
Another and more specific object is to provide such a safety seat having the following features and advantages.
1) The infant can be held in the seat in a comfortable position.
2) The seat is built of inexpensive materials, and therefore of low cost manufacture.
3) More specifically, the seat is made of foam material which is extremely light in weight, and strong, and can be specially shaped to provide the desired floatation effect.
4) Imbedded in the foam material is a core framework that facilitates shaping of the foam material and provides unusually great strength.
5) The device includes a bottom part forming a seat for holding the infant in upright position, and a canopy effective for turning the seat into upright position in the water, and providing a shade element for shading the infant.
6) The device has a specially shaped bottom surface on which it can rest on a dry surface, and be easily rocked for comforting the infant.

DETAILED DESCRIPTION OF THE DRAWINGS
FIGS. 1-6
show the safety seat of the invention in overall view. It is oriented in upright position in these views as if resting on a floor. The device mainly is in the form of a shell
21
having a front end
22
and a rear end
24
. It has a bottom
26
, a top
27
, a right side
29
, and a left side
30
. The sides of the device are identified according to its stationary attitude, i.e., right and left according to the respective sides of an observer viewing the device from the front, as in FIG.
1
.
The shell
21
is made up of a single one-piece integral article. It is made up basically of a plastic material
31
that can be applied as foam and which hardens after being applied, or instead, it may be molded of plastic material
31
that is adapted to injection molding processes, if desired.
The shell
21
(
FIG. 3
) includes what may be referred to for convenience as a bottom section
32
and a canopy
33
. A line
35
delimits the upper surface of the bottom or lower section
32
, at the right of the latter, and lies between the bottom section
32
and the canopy
33
, but the canopy
33
is integral with the bottom section
32
as indicated above. The juncture between the bottom section
32
and the canopy
33
is indicated by a line
36
in
FIG. 1
, and as a point
37
in
FIGS. 2 & 3
.
In forming the shell
21
, the plastic
31
is put in place around a supporting structure
38
which includes rods
38
′ and a wire mesh
38
″ interconnecting the rods
38
′. Attention is directed to
FIGS. 18 & 19
showing the shell
21
; as the plastic
31
is put in place, the supporting structure
38
is imbedded in the plastic
31
. The steel rods
38
′, are of U-shape, as shown at
39
below the axis line
39
′, and at
40
above the axis lines
40
′. The wire mesh
38
″ stretches across the transverse extent of the shell
21
. In other words, the rods
38
′ and mesh
38
″ form a skeleton frame work for supporting the plastic material
31
for providing strength and also in part, shape of the parts of the shell
21
. As the formation of the shell
21
proceeds, plastic material
31
is added and applied over the entire mesh
38
″ and rods
38
′. In this process, the plastic
31
of course, is elastic and can be shaped, and as it is applied, the mesh
38
″ is moved, or pushed, or flexed within reasonable limits to produce a desired shape, within small limits, to provide a desired shape for comfort for the infant
42
. The supporting structure
38
, including the rods
38
′ and mesh
38
″, not only allows a specific shape to be formed, but provides unusual strength. The plastic material
31
after having hardened, assumes substantial strength of its own, but the strength of the supporting structure
38
is added thereto to provide the total and unusually great strength to the entire shell
21
.
Those portions that may be referred to as walls or wall elements, such as at
41
, may be for example of 2½-3 inches in thickness. These dimensions are only examples and they may be of any thickness within a wide range.
The relative positioning of the bottom section
32
and the canopy
33
is such as to form an interior space or cell
43
(
FIG. 7
) in which the infant
42
is placed in the use of the safety seat. This cell
43
opens longitudinally through the front end, and is directed near the horizontal, as oriented in side view, along the axis
44
.
The bottom section
32
at the rear, as seen in
FIG. 3
, at
45
, is relatively thick in vertical dimension. This thick portion provides great flotation effect and has an inclined top surface
48
for comfort of the infant
42
. The top surface
48
is inclined upwardly and rearwardly at a substantial angle. The front portion
49
of the bottom section
32
has an upper surface
50
that slopes inwardly and downwardly, joining the surface
48
at
51
(see
FIGS. 3
,
7
,
8
). These two surfaces
48
,
50
are so arranged that the infant
42
when lying on the top surface
48
, his trunk is inclined upwardly enabling him to see the exterior, while the upper surface
50
is nearer the horizontal and more directly forms a seat on which the infant
42
sits. The shell
21
is fixed in structure and hence it is not necessary to move or remove anything to gain access to the interior.
The bottom section
32
is so formed that the wall elements
41
provide side arms at the sides of the infant seat. The canopy
33
is curved about an internal front-to-rear axis
71
(
FIGS. 1
,
5
,
7
). The top or outer convex surface of the canopy
33
approximates the cylindrical, and the side portions of the canopy
33
at
72
are disposed adjacent the vertical direction and merge into the side arms
41
.
The canopy
33
at the front terminates upwardly in a center extension
73
directed generally forwardly, and its outer convex surface at its top peak
74
forms the highest point of the shell
21
. This relationship will be referred to hereinbelow in describing the action of the device in the water. The outer convex surface approaches the spherical, for providing an essentially point engagement in the water.
The canopy
33
(
FIGS. 5
,
7
) does not extend the full length of the bottom section
32
. The extension
73
of the canopy
33
adds to the length of the canopy
33
for shade purposes, for shading the infant
42
when in position in the safety seat.
A bail
58
is detachably mounted in the walls
41
of the shell
21
, which has a segment or cross bar
60
for holding play things for the infant
42
.
For assisting in moving the seat to an upright position in the flotation step, weights
61
(
FIG. 9
) are utilized. These weights
61
as used herein are two in number and are individually identified
61
a
and
6
l
b
(FIGS.
10
&
11
), and imbedded in the bottom
26
of the shell
21
as shown in FIG.
6
. These weights
61
a
,
61
b
are preferably of cylindrical form but need not be of that exact shape. They are preferably approximately 5 lbs each in weight, although in this case also this dimension is not limiting. In the case of weight,
61
a
, it is positioned with its axis
62
a
transverse, while in the case of weight
6
l
b
it is positioned with its axis
62
b
longitudinal.
The bottom surface
26
of the shell
21
(
FIGS. 2 & 6
) is made up of three panels
63
,
64
,
65
. The center panel
64
is the largest, and it joins the rear panel
65
in a rounded surface
67
forming a rocking beam as referred to below. The front panel
63
is disposed at an angle to the center panel
64
along a line
68
. The rear surface
69
is approximately perpendicular to the center panel
64
.
A harness
52
is put in position in the shell
21
as shown particularly in
FIGS. 7 & 8
. This harness
52
is of known kind and need not be described in detail, but is put in position in the shell
21
or anchored therein (
FIG. 14
) by imbedding terminal elements
53
thereof in the plastic material
31
making up the shell
21
. These terminal elements
53
include flexible straps
54
and anchoring elements
55
extending into and imbedded in the plastic material
31
and secured to a plate
57
securely held in the plastic material
31
.
Considering the device as a safety seat, to be used as in a boat, as distinguished from resting on dry land, attention is directed to
FIGS. 15
,
15
a
in which the safety seat is shown in inverted position. The bottom section
32
, and particularly in the rear portion thereof, is of great vertical thickness, and consequently of much greater mass than the canopy
33
. By reason of this relationship, when the device is in the water, as from a fall or from being thrown into the water, and the top peak
74
is lowermost, the bottom section
32
tends to find the lowermost position with the canopy
33
extending upwardly. This feature, as presented in
FIGS. 15
,
15
a
is an extreme position. The top peak
74
in engaging the water, forms a fulcrum of minimum area which is basically a point contact. The great mass of the entire device extends upwardly therefrom and readily falls over, the weights
61
assisting in this rolling-over action.
The entire device is of low density, and sinks into the water only a short distance, as represented approximately in FIG.
16
.
The position of
FIGS. 15
,
15
a
would persist for only an instant of time, because the bottom part of the seat is overwhelmingly greater than the top part and consequently the seat would turn over or actually roll over. Such action would be about the top peak
74
, and in
FIG. 15
, the seat would roll toward the observer or in the opposite direction, or sideways. This sideways, rolling direction is shown more fully in
FIG. 15
a
. In this figure, the seat is viewed from the front, and the dotted line positions
21
′ represent the rolling over action in sideways direction. The relatively narrow width of the seat determines its rolling sideways, and the flat side of the seat first engages the water. Because of the greater size of weight of the seat, which includes the weights
61
, the rolling action continues and the bottom part moves the bottom position in the water and the canopy
33
to the upright position. The entire shell
21
is of substantial width, and thus is relatively stable when in an upright position.
One or both of the weights
61
a
,
61
b
, may be offset transversely to one side of the vertical longitudinal sectional plane
76
, as shown in FIG.
6
. This offset arrangement of the weights
61
a
,
61
b
adds to the rolling over of the device.
The top peak
74
is at a relatively great height compared with the width of the shell
21
, and when the shell
21
is in inverted position (
FIG. 15
) this relatively great height adds to the rolling over action. The dimensions of the shell
21
may be: length of bottom section
32
27
″; length of canopy
33
21
″; width
16
″; weight approximately 15 lbs. (with the weights
61
); but these dimensions and values may be varied.
While the device is primarily a safety seat for floatation in water, it is also well adapted to accommodating an infant
42
on dry land, such as on a pier or on the beach, or in the house. In any setting, or environment, it may be used for holding an infant
42
, releasing the parent from constant attention. The canopy
33
serves as a shield from the sun.
The center panel
64
is so positioned that it rests fully on the floor
80
(FIG.
3
), when the device is positioned thereon, and serves to hold the seat upright. The juncture surface
67
between the center panel
64
and the rear panel
65
, is rounded, or of long-radius cylindrical shape, facilitating rocking of the seat. This may be done by placing the toe of the attendant under the front panel
63
and rocking the entire seat about the rounded surface
67
.
The seat may be used in a boat for comfort of the infant
42
, aside from any consideration of danger. When in a boat, a parent may hold the infant
42
but that detracts from the complete relaxation and enjoyment of the boat ride. Hence the device may be used not only for safety purposes, but for convenience as well, forming an all-purpose device.
