Description
A. BENEFITS OF THE PRESENT INVENTION
[0001] The invention relates to a composite cushioning material
with shock-absorbing characteristics, and the method for making the
same. As described in greater detail below, this composite material
is flexible, relatively lightweight, and breathable. This
cushioning material can be used as an outer and inner cushioning
component in apparel, footwear, or headgear, or as wearable
protective padding; as cushioning pads in bags, carriers, and
containers; or as a component in athletic, industrial, or military
protective gear or equipment. The composite cushioning material can
be made flexible, so as to better follow the contours of the
wearer's body, joint areas, or extremities, or to envelop the body
parts that are intended to be protected, yet be lightweight and
breathable. The invention also relates to a method for making the
said composite cushioning material.
B. SUMMARY OF THE INVENTION
[0002] The invention relates to a composite cushioning material
comprising one or more resilient elements surrounded, or
"encapsulated," on all sides by at least two layers of sheeting
material.
C. BRIEF DESCRIPTION OF THE DRAWINGS
[0003] The present invention will become more fully understood from
the detailed description given herein below, and the following
accompanying drawings, which are given by way of illustration only,
and thus are not limitative of the present invention:

D. DESCRIPTION OF THE INVENTION
[0012] 1. FIRST COMPOSITE CUSHIONING MATERIAL
[0013] FIGS. 1A-1B and 2 depicts first composite cushioning
material 1, comprising a plurality of resilient elements 3
positioned, or "sandwiched," between two sheeting structures,
namely, first substrate 4 and second substrate 5.
[0014] FIG. 1B is a cutout view of the first composite cushioning
material 1, depicting the resilient elements 3 positioned above the
first substrate 4, and surrounded on all remaining sides, or
"encapsulated," by second substrate 5.
[0015] As shown in FIGS. 1B and 3, the bottom surface 3B of the
resilient element 3 makes contact with top surface 4T of the first
substrate 4. Portions of second substrate 5 are stretched over the
resilient elements 3, and top surface 3T and side surface 3S of the
resilient elements 3 are surrounded, or encapsulated, by first
encapsulating cover 6 and first encapsulating cover sidewalls 6S of
the second substrate 5. This can also be seen in the exploded view
of the first composite cushioning material 1, shown in FIG. 2. The
areas of the second substrate 5 between the resilient elements 3
make contact with first substrate 4, and are bonded along the
joining surface 8, as shown in FIG. 3.
[0016] While FIGS. 1-3 depict a composite cushioning material with
a plurality of resilient elements, it is understood that the
composite cushioning material may optionally incorporate a single
resilient element of suitable size and shape.
[0017] a. COMPOSITION OF THE RESILIENT ELEMENTS AND SUBSTRATES
[0018] In one aspect of the invention, the composition of the
resilient element 3 may optionally comprise, include, or
incorporate, without limitation, any suitable resilient material,
such as a foam or other elastomer, including, without limitations,
ethylene vinyl acetate ("EVA") foam, olefin or polyolefin foam,
polyurethane ("PU") foam, urethane based foam, thermoplastic foam,
neoprene, silicone, rubber, or any other material (including a
combination of such materials) with suitable cushioning
characteristics.
[0019] By way of example only, different resilient materials may be
combined by bonding sheets of different materials to each other in
vertical layers, or by bonding or sewing swatches of different
materials.
[0020] The resilient elements 3 may have any suitable shape and/or
size. While FIGS. 1-3 and FIGS. 4-6 depict resilient elements that
are cylindrical or drum-shaped, it is understood that the resilient
elements may have any suitable shape or size.
[0021] In another aspect of the invention, the composition of the
substrate elements or sheeting structures may optionally comprise,
include, or incorporate, without limitation, any suitable sheeting
material, such as synthetic or natural fabric, spandex or elastane,
mesh, natural or synthetic leather, thermoplastic polyurethane
("TPU") sheeting, or any other sheeting material (including a
combination of such materials) with suitable elasticity and
resistance to puncture or abrasion, or other desirable
characteristics, provided that the sheeting material is capable of
being loosely or tightly stretched over the resilient elements and
thereby "encapsulate" them. By way of example only, sheets of
different materials may be combined by bonding them to each other
in vertical layers, or by bonding or sewing swatches made of
different types of materials.
[0022] b. BONDING ELEMENTS JOINING THE MATERIAL LAYERS IN THE FIRST
COMPOSITE CUSHIONING MATERIAL
[0023] In one aspect of the invention, the two substrates (for
example, first substrate 4 and second substrate 5) may be bonded to
each other along joining surface 8 by means of any compound,
adhesive, glue, substance, attachment, or device (such as Velcro,
or interlocking mechanical means, or double sided adhesive tape,
and the like) that permits one substrate to adhere to another
substrate.
[0024] In an advantageous embodiment of the invention, the two
substrates are optionally bonded to each other using hot-melt
adhesive ("HMA") film activated by heat, or by heat and mechanical
pressure.
[0025] In another aspect of the invention, the resilient elements
(such as resilient element 3) may optionally be bonded to one or
more substrate elements (such as first substrate 4 and/or second
substrate 5). The bonding may occur by joining any one or more
sides of the resilient element to a substrate. By way of example
only, a joining element (such as glue or HMA film 9 depicted in
FIGS. 1B and 2) may optionally be applied to first substrate 4, and
cause the bottom surface 3B of the resilient elements 3 to bond to
the top surface 4T of the first substrate 4, and cause the bottom
surface 5B of the second substrate 5 to bond to the top surface 4T
of the first substrate 4 along the joining surface 8.
[0026] Alternatively, and optionally, a joining element such as
glue or HMA film 9 may be applied to the top surface 3T of the
resilient elements 3, and/or the bottom surface 5B of the second
substrate 5, causing the said elements to bond to each other. Also
optionally, a joining element may be applied to the side walls 3S
of the resilient elements 3, causing them to bond to the inner
surface of the first encapsulating cover sidewalls 6S.
[0027] In yet another aspect of the invention, the resilient
elements 3 are optionally not bonded to any substrate, and are
encapsulated and held in place by the first encapsulating covers 6
of the second substrate 5, which surround and encapsulate the
resilient elements within the void space 7 defined by loosely or
tightly stretching the second substrate 5 around the resilient
elements 3, and by bonding the edges around the void space 7 to the
top surface 4T of the first substrate 4.
[0028] 2. SECOND COMPOSITE CUSHIONING MATERIAL
[0029] In another alternative aspect of the invention, the
resilient elements 3 are optionally encapsulated by two sheeting
structures, such as third substrate 10 and fourth substrate 11
shown in FIGS. 4A-4B and FIGS. 5-6.
[0030] FIGS. 4A and 4B depict the second composite cushioning
material 30, wherein resilient elements 3 are surrounded on all
sides, or "encapsulated," by both third substrate 10 and fourth
substrate 11.
[0031] As shown in FIGS. 4B and 6, in the second composite
cushioning material 30, neither the top surfaces 3T nor bottom
surfaces 3B of the resilient elements 3 rest against a surface of a
substrate that lies flat along a single plane. (By way of
comparison only, first substrate 4 as depicted in FIGS. 1B and 3
does lie flat along a single plane).
[0032] As shown in FIGS. 4B, 5, and 6, portions of third substrate
10 are stretched over the resilient elements 3, and top surface 3T
and a portion of side surface 3S of the resilient elements 3 are
surrounded, or encapsulated, by second encapsulating cover 12. In
this optional embodiment of the invention, top surface 3T of the
resilient elements makes contact with the second encapsulating
cover inner surface 12T of third substrate 10.
[0033] As also shown in FIGS. 4B, 5, and 6, portions of fourth
substrate 11 are stretched over the resilient elements 3, and
bottom surface 3B and a portion of side surface 3S of the resilient
elements 3 are surrounded, or encapsulated, by third encapsulating
cover 14. In this optional embodiment of the invention, bottom
surface 3B of the resilient elements makes contact with the third
encapsulating cover inner surface 14B of fourth substrate 11.
[0034] As shown in the exploded view in FIG. 5, the resilient
elements in the second composite cushioning material 30 are
"contained" within void space 13 and void space 15 defined by
loosely or tightly stretching the third substrate 10 and fourth
substrate 11, respectively, around the resilient elements 3, and by
bonding the joining surface 16, that is, the surface areas of the
two substrates comprising the edges around the void spaces.
[0035] While FIGS. 4-6 depict a composite cushioning material with
a plurality of resilient elements, it is understood that the
composite cushioning material may optionally incorporate a single
resilient element of suitable size and shape.
[0036] It is also understood that the third substrate 10 and fourth
substrate 11 may be comprised of any material or combination of
materials used to fabricate the first substrate 4 or the second
substrate 5.
[0037] It is understood that the various materials and components
disclosed herein may be made of any suitable material and may be
any size and shape consistent with their functions. The specific
embodiments of the materials, components, and processes disclosed
