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.
