INFANT REST PAD
Abstract
Generally rectangular sheets of plastic vinyl are heat-sealed
together to form a pad with a resilient cushion defined by an
inflatable chamber which extends around a central rest area. When
inflated, the chamber forms a plurality of lobes with interposed
air pockets around the periphery of the pad. The lobes extend
toward the center of the rest area and act in effect as ramps which
direct a rolling infant back toward the center of the rest area.
The pockets provide air spaces to keep the infant from rolling
tightly up against the wall of the chamber and possibly
smothering.

Description
BACKGROUND OF THE INVENTION
This invention relates to a device for preventing an infant from
possibly rolling off of a bed or other elevated surface upon which
he has been placed to rest or feed.
SUMMARY OF THE INVENTION
The general aim of the present invention is to make it easier and
safer for parents to care for a small infant when away from home
through the provision of a novel portable device or rest pad upon
which the infant may be laid and left alone to feed or nap without
worry that he might roll over and smother himself or be injured by
rolling over and off the elevated surface supporting the pad.
A further object of the present invention is to construct the pad
with an inflatable chamber extending around the periphery of the
pad at a height which virtually prevents the infant from possibly
rolling off the pad.
More specifically, it is an object of the invention to construct
the chamber to have a novel shape not only to keep the infant from
possibly rolling up tightly against the walls and smothering but,
also, to redirect the energy of the rolling infant so that the
infant tends to roll back toward the center of the pad. In this
regard, the invention resides in the unique arrangement of lobes
and interposed pockets formed in the wall of the chamber along
opposite sides of the rest area.
These and other objects and advantages of the present invention
will become more apparent from the following detailed description
when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in the drawings for purposes of illustration, the present
invention is embodied in an infant rest pad 10 suitable for use on
the top of a bed (not shown) or other elevated surface to keep an
infant within a walled-in rest area 11 on the pad so that the
infant is prevented from rolling off the bed and possibly being
injured. In accordance with the primary aspect of the present
invention, a resilient cushion 12 integrally formed around the
periphery of the pad includes unique wall portions 14 disposed
along opposite sides of the rest area both for preventing the
infant from rolling off the pad and keeping the infant from
possibly smothering against the wall. For these purposes, the
cushion is defined by an inflatable chamber 13 having wall portions
which are constructed with a plurality of lobes 15 and interposed
pockets 15a. When the chamber is inflated, the lobes keep the
infant away from the wall by redirecting the infant to roll back
toward the center of the pad and the pockets provide air spaces
between the lobes to keep the infant from burying his head in the
cushion and possibly smothering.
In the present instance, the pad 10 comprises a plurality of
generally rectangular vinyl plastic sheets 16, 17 and 18 overlying
each other as shown in FIGS. 2 and 3. The bottom sheet 16 is
somewhat thicker than the two upper sheets 17 and 18 and includes a
cloth backing 19 embedded in the underside thereof to protect the
pad against punctures and to keep the pad from sliding across the
elevated surface during use. Alternatively, the underside of the
bottom sheet may be embossed to facilitate washing the pad. The two
upper sheets 17 and 18 are thinner than the bottom sheet and form a
double-ply top which has been found to be particularly effective in
stopping air leaks through the pin-sized holes (not shown) normally
found in thin plastic sheets.
As shown in FIGS. 2 and 3, the top two sheets 17 and 18 and the
bottom sheet 16 are heat-sealed together along two spaced
peripheral seams 20 and 21. The outer seam 21 defines the
circumference of the pad 10 as having two parallel sides 22 and two
parallel ends 23 connecting the sides with each other to form the
generally rectangular pad. The inner seam follows an irregular,
curving but generally rectangular path around the periphery of the
rest area 11 to define the rest area as having generally straight
and parallel opposite ends 25 which also are parallel with the ends
23 of the pad. The opposing sides 26 of the rest area are
scallop-shaped curved segments of the inner seam 20 which
alternately open toward and away from the center of the rest area
upon progressing between the two ends 25.
The space between the inner and outer seams 20 and 21 defines the
chamber 13 as including an upper wall 27 (see FIG. 2) formed by a
portion of the double-ply top and a lower wall 29 formed by a
portion of the bottom sheet 16, the two walls 27 and 29 being
connected to each other along the inner and outer seams. In the
exemplary embodiment, the inflated chamber approaches four inches
in height along the sides 26 of the rest area in order to keep very
young infants confined to the rest area 11. It will be appreciated,
however, that under differing circumstances it may be preferable
for the chamber to be of a greater or lesser height than the 4
inches.
To inflate the chamber 13, a valve 30 secured to the uppermost
sheet 18 extends through the double-ply top wall 27 and into the
chamber to permit air to be blown into the chamber. Preferably, the
valve is normally one-way acting to prevent air from leaking out of
the chamber back through the stem of the valve. In the present
instance, the stem of the valve must be pinched together in order
to deflate the chamber. Thus, through the use of this valve, the
chamber is kept from accidentally deflating.
When the chamber 13 is inflated, the lobes 15 are formed in the
upper wall 27 of the chamber along the opposing sides 26 of the
rest area 11 as a result of the outwardly opening curved segments
of the inner seam 20. Similarly, the inwardly opening curved
segments of the inner seam form the pockets 15a between the lobes.
As shown in FIG. 2, the upper surfaces of the lobes slant
downwardly from the top of the chamber, upon progressing toward the
inner seam to form in effect small resilient ramps which tend to
redirect an infant rolling upon them back toward the center of the
rest area. The pockets 15a provide air spaces between the lobes so
that an infant is kept from rolling up tightly against the cushion
12 and possibly smothering himself.
In another aspect, the present invention enables the infant to feed
from a bottle 31 without the bottle having to be held manually
while he nurses. For this purpose, a bottle holder 33 located on
top of the cushion 12 includes a recess 34 formed in the top wall
27 to support the bottle above the rest area 11. A strap 35
spanning the recess holds the bottle therein so that the infant can
feed himself.
Herein, two of the bottle holders 33 are formed integrally with the
pad 10, the holders being located on opposite sides of the rest
area 11 (see FIG. 1) so the infant may lay on either side when
nursing. More particularly, the recesses extend across the top of
the chamber generally at right angles with respect to the
longitudinal axis of the cushion 12 along each side 26 of the rest
area. The straps 35 are heat-sealed to the uppermost plastic sheet
18 along opposite sides of the recesses as shown in FIGS. 1 and 4
for holding bottles within the recesses.
While one of the main advantages of the present invention resides
in the use of the pad 10 to keep the infant from rolling off an
elevated surface when he is resting or feeding, other additional
advantages of the pad are readily apparent. For instance, since the
pad is made of plastic and is impermeable, it makes an excellent
covering upon which diapers may be changed without worry of
possibly causing damage to the surface supporting the pad.
Moreover, when the pad is not in use, it may be deflated and folded
into a small, easily portable package. Thus, it will be appreciated
that the present invention as embodied in the unique pad 10 makes
it much easier, safer and more convenient to care for an infant not
only when away from home but also in the home itself.
