AMPHIBIOUS CARRIER AND METHOD OF MANUFACTURING
Abstract
An all weather amphibious carrier and method for manufacturing
thereof, for use on land and in water, which includes an adjustable
strap system for wearing by a person; a foldable body or member
adjustably attachable to the strap system and capable of supporting
an infant or child upon folding the member and attaching the member
to the strap system; the strap system being made of
weather-resistant, synthetic, polymerized rubber, a high-strength,
resilient synthetic polymer, and a polymer containing polyurethane;
and the foldable body member being made of a weather-resistant,
synthetic, polymerized rubber, a synthetic fabric made from a
polymer containing polyurethane; and a flexible polyurethane
open-cell antimicrobial-coated foam. The unique combination of
materials keeps the baby/toddler from becoming sweaty when used for
land activities, because the materials breathe. When used in water,
rain, and snow, it dries quickly, because the water can pass
through the through the body if conventional stitching is used or
the body can be completely water-tight by using flatlock,
breathable seams. The special quilted design also adds extra
support, comfort and security for both care-giver/parent and baby,
making this carrier ergonomically sound, both on land and in
water.

Description
[0001] This application claims the benefit under 35 U.S.C.
.sctn.120 of co-pending U.S. patent application Ser. No. 11/242,847
filed on Oct. 5, 2005 which claims benefit under 35 U.S.C
.sctn.119(e) filed on Oct. 6, 2004, which are both hereby
incorporated by reference in their entirety.
BACKGROUND TO THE INVENTION
[0002] I. Field
[0003] The present invention concerns an amphibious carrier and a
method of manufacturing the carrier, for carrying an infant or
child that can be used both in all weather conditions on both land
and in water. The carrier is constructed is such manner that it
dries quickly without mildewing or mold.
[0004] II. Art
[0005] Baby carriers are well known and generally they are designed
either for use in dry conditions or for use in water. Generally,
these type carriers are designed and made of materials that are
suitable for dry use or designed and made of materials primarily
for use in water.
[0006] Certain baby carriers designed for use in water have been
developed. These, however, are not without their drawbacks. Some
carriers of this type may be designed for larger babies and not for
very small infants.
[0007] As well, other front-position baby carriers known on the
market, especially some designed for water-use, carry the baby very
low on the adult, around the stomach region. Most baby carriers are
used for approximately seven months. After that, the baby becomes
too heavy for most adults to comfortably carry.
[0008] One such carrier is disclosed in U.S. Ser. No. 20050076856
A1 filed on Oct. 29, 2004 and published on Apr. 14, 2005. Although
this carrier is designed primarily for use in water, it is not
constructed in such a way and is not made of materials that allow
it to be used in all weather conditions amphibiously on both land
and in water and without mildewing or molding after use in water.
Two other infant carriers are made by Body Glove
(http://www.bodyglove.com/products/product.php?uselist=showcase&sel-
ected_prod=http%3A%2F%2Fbodyglove.mwrc.net%2Fxml%2Fen%2Fproduct.xml
%3Fproduct_id%3D5746%26include_offline_products%3Dyes%26include_offline_r-
etailers%3Dyes) and WaterTot (http://www.watertot.com/product.asp),
and although they use neoprene, on a portion of the strap system
and on the seat member of the carrier, they do not use the unique
and novel design, construction and combination of materials of the
strap system and body of the present invention.
[0009] It would be desirable to improve upon the foregoing prior
art carriers, and overcome the problems associated with them. It
would be especially desirable to provide a versatile all weather
amphibious carrier for use on land and in water environments for
use with babies and toddlers spanning several years in age.
DISCLOSURE OF THE INVENTION
[0010] In general, the present invention provides an all weather
amphibious carrier, for use on land and in water, which comprises
an adjustable strap system for wearing by a person; a foldable
member adjustably attachable to the strap system and capable of
supporting an infant or child upon folding the member and attaching
the member to the strap system; the strap system being made of
weather-resistant, synthetic, polymerized rubber, a high-strength,
resilient synthetic polymer, and thermoplastic resinous polymers;
and the foldable member being made of a weather-resistant,
synthetic, polymerized rubber, a synthetic fabric made from a
polymer containing polyurethane; and a flexible polyurethane
open-cell antimicrobial-coated foam. The unique combination of
materials keeps the baby/toddler from becoming sweaty when used for
land activities, because the materials breathe. When used in water,
rain, and snow, it dries quickly, because the water goes right
through the materials. The special design also adds extra support
and security for both caregiver/parent and baby, making this
carrier ergonomically sound, both in and out of water.
[0011] The invention is useful in baby/infant care and recreation,
because its unique fabric and construction make it possible for you
to keep your baby or toddler close to you, safely and securely, on
both land and water. Because of its unique design, construction and
materials' properties, the invention is suitable for use in other
products where these characteristics are desirable. The materials
used and manufacturing technique gives the carrier strength and
comfort and as a result the invention is applicable to other items
such as snow and winter apparel, beach and sun apparel, diaper
bags, beach bags, and physical fitness accessories, such as gym
bags and the like.
[0012] The carrier of the present invention is versatile, as it can
quickly be adjusted to fit all sized adults and babies or toddlers.
It can be used with tiny infants lacking the strength to control
his/her the neck. The baby can be placed in the carrier to face
either in toward the adult or out, facing forward away from the
adult, giving the adult safe and complete control of the baby. The
carrier is made to be worn in front, although other designs may be
constructed. It is simple and easy to put on--the adult just slips
strap system shoulder straps onto the shoulders, with the body of
the carrier in front. A waist buckle is provided on each side so as
to buckle to the buckle piece of each shoulder strap, which can be
tightened or loosened as necessary. The body of the carrier is
designed to support the baby's head and back, as well as allow
freedom of the baby's arms and legs for splashing and kicking when
used in the water. The carrier is designed for babies from less
than 10 through 35 pounds and at least 21 inches long.
[0013] The shoulder straps cross in back, allowing even
distribution of weight and support. The combination of specially
quilted design and the materials from which the strap system and
body are designed and the way they are constructed make the carrier
novel, unique, extra comfortable, and ergonomically sound for both
care giver/adult and baby/toddler.
[0014] When the carrier gets wet, because of the construction and
particular materials used, it dries very quickly. Even if it gets
dirty, sandy, or muddy, the carrier is completely washable and is
cleaned very easily. The secure fit and convenience of hands free
ensures safety and comfort.

[0048] With further reference to the drawings, the carriers shown
in FIGS. 1 and 2 represent prior art carriers. The carrier in FIG.
1 is made by Water Tot and a similar carrier, not shown, is made by
Body Glove. FIG. 2 is a front view of the prior art carrier
depicted in U.S. patent application Ser. No. 20050076856 A1. None
of these prior art carriers have the design, construction or
combination of materials that makes the carrier of the present
invention superior to and patentably distinguishable from these
prior art carriers as will be described below.
[0049] The carrier 1 shown in FIGS. 3-5 generally includes two main
parts that are integrated into a single unit. Basically, the first
of these parts is a fully adjustable, criss-crossed shoulder and
back strap system including shoulder/back straps 2, 2' worn by the
adult caregiver and which distributes the weight of baby or infant
being carried. The second of these parts is the main body 8 in
which the infant or baby sits when the body 8 is appropriately
folded.
[0050] The main body 8, is soft and made to be positioned around
the adult's midsection to allow the seated child to ride high on
the adult's chest so that the adult's chin should be able to touch
the top of the baby's head. Adjustment of the strap system having
the straps 2,2' with main body 8 can be carried out conveniently
through lockable plastic buckles. Each strap 2, 2' has a series of
three spaced-apart plastic D-rings 6, 6' secured on the outer sides
of straps 2, 2'. The highest D-rings 6, 6' are located where the
straps rest on the adult's shoulders and the other two D-rings are
spaced about three inches apart extending downwardly from the
highest D-rings as seen in FIG. 4. D-rings 6, 6' are secured to the
side of shoulder/back straps 2, 2' facing away from the adult by
1-inch wide straps 7, 7' made of nylon webbing or polypropylene
webbing or other suitable polymeric material as shown in FIG. 7.
The child can be securely positioned in the bottom end of body 8
with the combination of buckles and Velcro pieces as will be
described below. The carrier can be designed for the adult
caregiver to slip on the adjustable shoulder/back straps 2,2' over
the adult's head and shoulders and the height adjustment is
accomplished by swivel hooks being snapped onto the appropriate
D-rings 6, 6'. The additional D-rings 6, 6' may be used for hanging
other useful items such as toys, and other baby items to them.
[0051] The carrier includes an adjustable head support 10 which is
an integral part of the top portion of body 8 (FIGS. 3, 4, 7) that
can be attached to the shoulder/back straps 2,2' as will be
described. Head support 10 as shown in the FIGS. is a solid area of
the body 8. However, in an alternative embodiment to allow for more
air flow around the baby's head and decrease perspiration, head
support 10 could have shoelace-type eyelets mounted through the
body across the area of the head support, as well as one or more
mesh panels to allow more airflow. FIG. 7 shows the inside of the
body 8 against which the baby rests. The body 8 has upper tabs 12,
12' and lower tabs 14, 14', which together form the openings
through which the baby's arms can hang freely from the body 8. The
upper tabs 12, 12' have common type adjustable, plastic swivel
hooks 22, 22' secured to the tabs 12, 12' by 1-inch wide nylon
webbing straps 23, 23' secured to tabs 12, 12'. Optional strap
protectors 26, 26' (see FIGS. 4 and 8) can be provided which slip
over each strap 23, 23' to make the area around the upper tabs 12,
12' more comfortable for the baby. Protectors 26, 26' are
preferably made of neoprene or similarly suitable material for use
in water. The upper tabs 12, 12' of body 8 are secured by hooks 22,
22' being snapped around the appropriate one of the D-rings 6, 6',
depending on the size of the baby being carried. Further adjustment
can be accomplished by tightening the nylon webbing straps 23, 23'
using 1-inch strap adjusters 23A, 23A through which the nylon
webbing straps 23, 23' pass.
[0052] The lower tabs 14, 14' have common snap-in type buckle ends
24, 24' secured to the lower tabs 14, 14' by 3/4-inch wide nylon
webbing straps 24A, 24A', as well as Velcro pieces 25, 25' secured
to the inner side of the lower tabs 14, 14' respectively. The lower
portion of body 8 tapers into portion 27, which when folded up and
back toward the head support 10 forms the seat for holding the
child as will be further described.
[0053] When the body portion 27 is folded forward and upward toward
the head support 10, the lower portion 27 and the lower tabs 14,
14' together form the openings through which the baby's legs extend
out from body 8 and the place where the baby sits in the carrier.
Also attached to the lower portion 27 is the nylon webbing waist
strap 17, which has standard adjustable snap-in style buckles 18,
18' attached at the ends 16, 16' respectively thereof. Buckles 18,
18' are place around the waist of the adult toward the back to
snap-in respectively to buckle ends 20, 20' shown in FIG. 6 at the
lower ends of shoulder/back straps 2,2'.
[0054] Extending from and secured to the lower portion 27 of body 8
are the other ends of straps 2, 2' as seen in FIGS. 5, 6 and 8.
Extending outwardly and secured to straps 2, 2', between the lower
portion 27 and D-rings 6, 6', are 2-inch wide nylon webbing tabs
30, 30' respectively. Tabs 30, 30' have Velcro tabs 32, 32' secured
on the inner side next to the neoprene side of straps 2, 2' and
adjustable snap-in buckle ends 34, 34' are respectively secured to
tabs 30, 30' by 3/4 inch nylon webbing straps 35, 35' on the same
side of tabs 30, 30' as the Velcro tabs 32, 32'. The view in FIG. 7
is of the outer nylon webbing side of straps 2, 2', so that
portions of the buckle ends 34, 34' are shown in dotted form behind
the nylon webbing side of tabs 30, 30'. Velcro tabs 32,32' are also
located on the inner sides of tabs 30, 30' as seen in FIG. 7. When
the lower portion 27 of body 8 is folded forward and upward, the
buckle ends 34, 34' are engaged to snap-in to the mating buckles
24, 24' located on the lower tabs 14, 14' of body 8 (see FIG. 5)
and the Velcro tabs 32, 32', each approximately 2-inces wide and
3-inces long, are secured to the mating Velcro tabs 25, 25'
respectively on the inner side of the lower tabs 14, 14' of body 8.
The combination of buckle ends 34, 34' and buckles 24, 24' and
Velcro tabs 32, 32' and 25, 25' respectively provide a double
locking mechanism for securing the lower portion 27 of body 8 to
the lower tabs 14, 14' to safely, snugly and securely hold the baby
in the lower seat portion formed by body 8.
[0055] Although buckles 18, 18' and 24, 24', buckle ends 20, 20'
and 34, 34', swivel hooks 22, 22', and D-rings 6, 6' are all shown
as made of plastic, they could easily be made of metal, composites
or other suitable lightweight, non-corrosive materials. Buckles 18,
18' and buckle ends 20, 20' are 2-inches wide and buckles 24, 24'
and buckle ends 34, 34' are 3/4-inches wide. The straps 16, 16' and
tabs 30, 30' are made of 2-inch wide nylon webbing, straps 23, 23'
are made of 1-inch wide nylon webbing, and straps 24A, 24A' are
made of 3/4-inch wide nylon webbing, but they could all be made of
other suitable, non-stretchable materials, such as polypropylene
webbing or other suitable polymeric material. The buckles and
buckle ends, which are simple side release buckles, swivel hooks
and D-rings are commercially available from the John Howard
Company, Inc. of Chino, Calif.
[0056] The shoulder/back straps 2, 2' are constructed of two layers
as shown in FIG. 6A along the entire length of straps 2, 2'. The
inner layer 50, which rests against the adult and is made of
weather-resistant, synthetic, polymerized rubber, such as for
example a 1.0 to 3-mm thick sheet of neoprene, secured face-to-face
to an outer layer 52 which is made of a high-strength, resilient
synthetic polymer, such as for example 2-inch wide nylon webbing.
Waist strap 17 is 2-inches wide and is made of nylon webbing or
polypropylene webbing. Outer layer 52 could also be made of
polypropylene webbing or other suitable polymeric webbing. The
nylon webbing and polypropylene webbing are commercially available
from the John Howard Company, Inc. of Chino, Calif.
[0057] The two layers 50 and 52 of straps 2, 2' are stitched
together with an industrial strength thread and a polymer
containing polyurethane edging 54 is wrapped around both outer
edges of straps 2,2' as seen in FIG. 6B. Edging 54 is made, for
example, of spandex or Lycra, and is stitched along the edges of
and through both the layers 50 and 52 to keep them securely
attached together and to prevent fraying of the edges of layers 50
and 52. The inner layer 50 is made of thermoplastic resinous
polymers that are a water buoyant fabric while in water, for
example, neoprene. The outer layer 52 is made of a polymeric
webbing material, such as nylon webbing, to give the straps 2, 2'
their carrying strength. Neoprene stretches too easily and cannot
be used alone for the weight-bearing straps 2, 2'. By making the
straps 2, 2' of the neoprene layer 50 and nylon webbing layer 52,
they are strong and provide more than adequate support for carrying
the baby, while providing a quick-drying, non-mildewing and
non-mold-forming material, through which water or body moisture is
not trapped and moves easily through. When the carrier gets wet,
because of the construction and particular materials used, it dries
very quickly. Even if it gets dirty, sandy, or muddy, the carrier
is completely washable and is cleaned very easily. The secure fit
and convenience of hands free use ensures safety and comfort for
both adult and baby.
[0058] The body 8 as seen in FIG. 7A is made of an inner layer 56,
an outer layer 58, both made of a weather-resistant, synthetic,
polymerized rubber, such as for example neoprene, of 1.0 to 3-mm
thickness. Secured between layers 56 and 58 is a layer 60, made of
an antimicrobial-coated foam of approximately one-half inch in
thickness and of medium density. The edges of the three layers 56,
58 and 60 of body 8 are secured together just as straps 2, 2' with
a polymer containing polyurethane the same as edging 54 as seen in
FIG. 6B, such as for example spandex or Lycra. The edging 54 is
stitched all along the edges of and through both the layers 56, 58
and 60 all the way around body 8 to keep the layers securely
attached together and to prevent fraying of the edges of layers 56,
58 and 60. The neoprene together with the open-cell foam, gives the
carrier extra cushion, support and comfort for baby/toddler during
all safe land and water activities, year round. The foam layer 60
has an antimicrobial coating that prevents mildewing and mold from
growing. This foam is variously called dry foam, outdoor foam or
open cell foam and is commercially available from various companies
including Foamex InternationaL Inc. of Linwood, Pa. Foamex
polyurethane foam is a fully cross-linked reaction product of
polyhydroxy polyol, touluene di-isocyanate, catalysts, surfactants,
pigments and water. Polyurethane foam is a polymeric material
consisting of repeating units of carbon, hydrogen, oxygen and
nitrogen. When the carrier 1 is in water or gets wet, the water
passes into the interior of the outer neoprene layers 56 and 58
where the regular type of stitching of edges 54 is used when they
are sewn together, but the anti-microbial coated foam layer 60 does
not soak up the water. Therefore, the carrier dries very quickly.
The open cell foam layer 60 does not hold or soak up the water like
a sponge. Foam 60 generally takes the form of a piece of rubber
that has been shaved at different thicknesses and can have many
different types of fabric laminated to it, such as the nylon and
lycra used for the strapping and edging of the carrier. When the
carrier is sewn together using regular stitching, the holes from
the stitching, though allowing small amounts of water to enter,
because of the open cell foam, water is not held by or soaked up by
the foam.
[0059] Another alternative to regular stitching is to completely
seal the outer edges of body 8 and stitching 62 so that no water
passes through the outer edges of body 8 or through the stitching
so it is completely water-tight. Edge sealing can be accomplished
by flatlock stitching to provide breathable seams. Flatlock
stitching is serging two layers of fabric together, then pulling
them apart until the seam lies flat. It takes some experimentation
to get the tension just right. Too loose a tension and the seam
pulls away, too tight and it is difficult to get the seam to lay
flat. Another way to accomplish a flatlock-type stitch is as
follows. Serge the edges of the seams to be joined, trimming off
the seam allowance. Place the two serged edges together, then using
a zig-zag stitch, sew the two sides together. Sometimes it may be
desired to use a three step zig-zag; this creates a sturdier seam,
but flattens the serging more. This flatlock-type seam will be
considerably wider than normal flatlocking, but in some cases the
trade off may be worth the ease of completion. If desired, a
decorative thread made of nylon can be used to zig-zag the seam for
added texture. It is also possible to seal the outer edges of body
8 using a no stitch technology and a 4 mm Metallite neoprene,
laminated with a Diamond-Tuff nylon construction system where not a
single stitch is used to seal the outer edges of body 8. This type
seal is commercially available and is described at
http://www.naval-technology.com/contractors/diving/fitzwright/,
which description is incorporated herein by reference.
[0060] The body of the carrier 1 is first sewn together using a
straight stitch leaving the bottom end of lower portion 27 open
approximately 3 inches. The edges are then bound with lycra trim.
The antimicrobial-coated foam is stuffed through the bottom making
sure the foam lays flat against the inside edges of the carrier 1.
Once the foam is flat and smooth it is stitched all around the
edges of body 8 and held in place using specific stitching lines 62
as shown on the pattern in FIG. 7. It is the stitching that creates
quilted sections 63 on the body 8 as seen in FIG. 7 that gives
strength to the body 8 of the carrier by allowing for minimal
stretch. Without this the carrier would stretch too much and loose
its shape.

[0096] a. Trace, with the erasable sewing chalk, the top stitching
on Pattern A (only one side of Neoprene).
[0097] b. Lay both pieces of neoprene body 56 and 58 (wrong sides
together), matching all edges (the piece with the seamline tracings
will be considered the right side of the neoprene. Using trim
edging 54, sew 1/4 inch lycra trim around edges, leaving bottom
open. If a water-tight seal is desired, this is where the flatlock
stitching techniques described above may be used. Take the
Open-Cell Foam piece 60, and place it between the 2 Neoprene pieces
56 and 58 of Pattern A, with the back sides together. Carefully
stuff foam in bottom opening of body member 8, making sure foam is
fitted into all corners and curves.

(see FIGS. 3A and 5).
[0120] l. If desired, all the stitching may be accomplished with
flatlock stitching techniques to create a completely water-tight
product.
[0121] The child is held securely in the carrier in seat formed in
the lower part of body 8. The carrier is designed for small
children with and without neck control. For infants or other
special needs children who do not have neck control, the head
support 10 built integral with body 8 is provided. The head support
can also be used when the baby is place in the carrier to face the
adult.
[0122] The carrier 1 is used and adjusted as follows. The shoulder
straps 2, 2' are placed over the adult's head with the body 8
positioned on the adult's chest and the strap stabilizer 4, made of
4 mm thick neoprene, resting flat on the adult's back between the
bottom 1/3 of the adult's shoulder blades. See FIG. 3A. The left
and right waist buckles 18, 18' are snapped into the buckle ends
20, 20' on the ends of straps 2, 2'. The ends of straps 2, 2' are
then pulled until the carrier fits snugly against the adult's body.
Before the baby is placed in the carrier, the waist buckles 18, 18'
are fastened and tightened. One side of the carrier is completely
fastened. This is accomplished by ensuring that buckle 24 on lower
tab 14 is snapped into buckle end 34 of tab 30 and Velcro tab 32 is
engaged with Velcro tab 25 on the inside of lower tab 14 of body 8.
If preferred the other side could be fastened instead. Then the
open side of the carrier is closed. This is accomplished by first
attaching Velcro tab 32' on tab 30' to the Velcro tab 25' on the
inside of lower tab 14' of body 8. Buckle 24' is then snapped into
buckle end 34' on the end of tab 30, closing the buckle 24' over
the Velcro engaged tabs 32' and 25'. Upper tab 12' is then attached
to shoulder/back strap 2' by latching the swivel hook into D-ring
6'. Further adjustment of the carrier is provided, depending on
which of the three D-rings 6, 6' the swivel hooks 22, 22' are
attached. The end of nylon webbing strap 23' is pulled on to
tighten and adjust the fit.
[0123] The baby is then placed in the carrier through the open
side, making sure the baby's arms are through the armholes formed
between the upper tabs 12, 12' and lower tabs 14, 14' of body 8.
Check to make sure that the back and waist are securely buckled.
Pull straps 16, 16', 23, 23' and 24A, 24A' so as to provide a
secure and snug fit.
[0124] The baby may be placed in the carrier facing in toward the
adult. First attach Velcro tabs 32, 32' and 25, 25' respectively.
Fasten buckles 24, 24' into buckle ends 34, 34' to ride over the
engaged Velcro tabs. Latch one side of the carrier by fastening
swivel hook 22' of upper tab 12' to D-ring 6' on shoulder strap 2'.
Pull on the end of nylon webbing strap 23' to adjust the fit.
Making sure the openings for the legs on both sides are open and
that buckle 18' is snapped into buckle end 20' on strap 2, pull on
the waist strap end 16' to ensure a snug fit. Adjust the carrier
until the baby rides high on the adult's chest. The adult's chin
should be able to touch the top of the baby's head. By placing the
carrier high on the adult's chest the stress on the adult's lower
back is reduced.
[0125] The baby may also be placed in the carrier facing outward
away from the adult. This position is appropriate for babies that
are able to hold their heads and shoulders in an upright position.
Place the baby in the carrier facing out through the open side.
Make sure the baby's legs straddle the seat formed at the bottom of
body 8. In this position the head support 10 portion of the body 8
should be folded down about 4 inches so that the baby's arms are
over the armholes that would normally be formed by upper and lower
tabs 12, 12' and 14, 14'. Attach the Velcro tabs 32' on tab 30' and
25' on the inside of lower tab 14' of body 8. Fasten buckle 24'
into buckle end 34' on tab 30' so that the buckle rides over the
fastened Velcro tabs 32' and 25'. Latch the upper tab 12' by
fastening swivel hook 22' to D-ring 6'. Further adjustment of the
carrier is provided, depending on which of the three D-rings 6, 6'
the swivel hooks 22, 22' are attached. Adjust upper and lower tabs
12, 12' and 14, 14' respectively by pulling on the ends of straps
23, 23' and 24A, 24A' so that the baby's back fits snuggly against
the adult's chest. For smaller babies, the baby's arms should go
through the armholes formed by upper and lower tabs 12, 12' and 14,
14' of body 8. For larger babies with good upper body control, the
arms can rest over the folded-over upper tabs 12, 12' and head
support 10. Adjust straps 16, 16', 23, 23' and 24A, 24A' as
necessary to ensure a snug fit.
[0126] Although the carrier shown in the FIGS. describe and show a
baby carrier for carrying the baby in the front of the adult,
modifications could be made by those skilled in the art so that a
carrier containing the unique and novel combination of elements of
the present invention could be incorporated in a back carrier or
side carrier to be worn on the adult's side body. The combination
of design, construction and materials of the present invention
could also be used by those skilled in the art to make other types
of carrying devices for amphibious use on land and in water. The
fact that the neoprene is quilted with the foam in between the
neoprene layers gives it strength and comfort and makes it
applicable to other items such as snow and winter apparel, beach
and sun apparel, diaper bags, beach bags, and physical fitness
accessories, such as gym bags and the like.
[0127] Various features, parts, and combinations can be utilized by
those skilled in the art in the practice of the invention, and
numerous adaptations and modifications can be made within its
spirit, the literal claim scope of which is particularly pointed
out in the claims.
