Description
FIELD OF THE INVENTION
[0001] The present invention relates to multilayer laminate
footwear insoles, methods for manufacturing the insoles and methods
for sizing the insoles.
BACKGROUND
[0002] Removable insoles are generally inserted into shoes, in
order to provide added cushioning and support for the wearer of the
shoes. These insoles are typically made as a one-size-fits-all
product, and the consumer purchasing the insoles must trim them to
an appropriate size using scissors or similar means to cut through
the material of the insoles.
[0003] An insole is generally constructed of multiple layers of
material, many of which are not easily cut with scissors by
consumers. To cut through the material, the consumer must carefully
follow a trim pattern that is printed on, molded in or applied to
the insole. Consumers typically do not like to trim insoles with
scissors for fear of misaligning the pattern while cutting or not
cutting the correct mark on the pattern.
[0004] U.S. Pat. No. 4,864,740 describes a disposable hygienic shoe
insole having three layers: a top layer of spunbonded polypropylene
material, a composite layer of pulp fibers and polypropylene fibers
meltblown onto the top layer, and a bottom layer of polyethylene
vinyl acetate meltblown onto the composite layer. The insole
includes line perforations at the front and inner arch portions of
the insole to allow a user to reduce the length and width of the
insole. In addition, the insole includes lines of perforation
across an arch area of the insole. These latter lines of
perforation allow the length of the insole to be shortened by
tearing off a portion of the arch area of the insole and
subsequently reattaching toe and heel sections of the insole.
[0005] U.S. Pat. No. 6,526,676 describes a disposable sandal formed
of a piece of sheet material including a fabric laminated to
polyurethane foam. A series of perforations are provided at the
heel and/or toe portions of the sole of the sandal to allow the
sandals to be sized to a user's foot.
[0006] U.S. Pat. No. 3,925,914 describes a sandal, whose sole
member may be made of a laminate having a bottom layer of
thermoplastic material and a top layer of fibrous material. The
sole member may be provided with rows of holes at the toe and heel
ends, in order to allow the sandal to be shortened by breaking away
a portion of the sole member at the holes. The holes do not go
through the entire sole, but instead, a break-away or tear-away
portion is left at the bottom of each hole.
[0007] However, none of the aforementioned references describes an
insole, that may be cleanly sized by a consumer without the use of
mechanical cutting instruments.
SUMMARY
[0008] Accordingly, a need has been recognized for a footwear
insole that may be sized simply, neatly and without use of a
mechanical cutting instrument by a consumer.

multilayer laminate footwear insole comprising a top layer having a
top surface, a bottom layer having a bottom surface, wherein the
bottom layer includes at least one cushioning layer, a channel in
the insole, wherein the channel transects the top layer of the
insole, and one or more punctuations in the channel, wherein the
punctuation transects the bottom layer of the insole.
[0010] In an alternative non-limiting embodiment of the invention,
the channel completely transects the top layer.
[0011] In an alternative non-limiting embodiment of the invention,
the punctuation in the channel transects the bottom surface of the
bottom layer.
[0012] In an alternative non-limiting embodiment of the invention,
the channel penetrates at least part of the bottom layer.
[0013] In an alternative non-limiting embodiment of the invention,
the channel traverses the top surface of the top layer from
opposing edges of the insole.
[0014] In an alternative non-limiting embodiment of the invention,

[0015] In an alternative non-limiting embodiment of the invention,
the foam layer comprises at least one of polyurethane, ethylene
vinyl acetate copolymer and styrene-ethylene-butadiene-styrene.
[0016] In an alternative non-limiting embodiment of the invention,
the at least one cushioning layer is a gel layer.
[0017] In an alternative non-limiting embodiment of the invention,
the gel layer comprises at least one of polyurethane,
styrene-ethylene-butadiene-styrene, silicone or hydrogel.
[0018] In an alternative non-limiting embodiment of the invention,
the top layer includes at least one fabric layer.
[0019] In an alternative non-limiting embodiment of the invention,
at least one fabric layer comprises at least one of a polymer or
natural fiber.
[0020] In an alternative non-limiting embodiment of the invention,
the channel is laser cut.
[0021] In an alternative non-limiting embodiment of the invention,
the punctuation is made in predetermined patterns.
[0022] In another non-limiting embodiment of the present invention,
a method for manufacturing a multilayer laminate footwear insole
having a top layer with a top surface, a bottom layer with a bottom
surface, wherein the bottom layer includes at least one cushioning
layer, comprises the steps of cutting a channel in the top surface
of the top layer of the insole, wherein the channel transects the
top layer of the insole, and punctuating the bottom layer in the
channel.
[0023] In an alternative non-limiting embodiment of the invention,
the punctuation transects the bottom surface of the bottom layer of
the insole.
[0024] In an alternative non-limiting embodiment of the invention,
the cutting includes cutting two or more channels.
[0025] In an alternative non-limiting embodiment of the invention,
the top layer is partially transected by the channel.
[0026] In an alternative non-limiting embodiment of the invention,
the channel is cut using a laser.
[0027] In yet another non-limiting embodiment of the present
invention, a method of reducing a dimension of a multilayer
laminate footwear insole for altering a size of an insole having a
predetermined punctuated channel, comprises the step of tearing the
insole by hand along the predetermined punctuated channel.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0044] A need has been recognized for a footwear insole, whose size
may be adjusted by consumers without mechanical cutting instruments
such as scissors, even when the insole includes a layer or layers
of high-strength fabric and/or high-strength and/or elastic
cushioning materials.
[0045] FIG. 1 is a schematic plan view, and FIG. 2 a schematic
cross-sectional view along line A-A', of a non-limiting embodiment
of an exemplary footwear insole 10. The footwear insole 10 includes
a toe portion 20, a heel portion 30 and a medial arch portion 40
interconnecting the toe and heel portions 20, 30. The insole may
also include a top layer 50 and a bottom layer 60 affixed to the
top layer 50. The top layer 50 may include one or more fabric
layers, and the bottom layer 60 may include one or more cushioning
layers, such as foam layers and gel layers. However, the top layer
50 may also include foam and/or gel layers. For the sake of
simplicity, though, the embodiments discussed in the following will
include a top layer 50 made of a layer of fabric and a bottom layer
60 made of a layer of foam or gel. The fabric layer 50 may include
at least one polymer or natural fiber such as polyester, acetate,
polyethene, acrylic, nylon, rayon, spandex, wool, cotton, silk,
bamboo, linen, hemp, urethane, or any material that can be ablated
by a laser. In addition, fabric layer 50 may include at least one
film, such as polyethylene, polyurethane, or any other material
that can be ablated by a laser. Any foam layer used as the bottom
layer 60 may include at least one of polyurethane, ethylene vinyl
acetate copolymer, styrene-ethylene-butadiene-styrene or other
suitable materials for cushioning. Any gel layer used as the bottom
layer 60 may include at least one of polyurethane,
styrene-ethylene-butadiene-styrene, silicone, hydrogel or other
suitable materials for cushioning. The footwear insole 10 may take
any of a variety of shapes in order to fit within a variety of
shoes. Also, the footwear insole 10 may have any of a variety of
contoured, flat, curved, or other surfaces in order to fit within a
variety of shoes. Further, the tear strength of the top layer may
be greater than the tear strength of the bottom layer.
[0046] FIG. 3A is a schematic view of a laser cutter cutting a
channel into a footwear insole 110, according to an embodiment of
the present invention. The laser cutter 112 focuses a laser beam
114 onto the footwear insole 110 (shown in cross-section) and is
moved across a surface of the footwear insole 110 so as to cut a
depression or channel 116 into the footwear insole 110. The laser
cutter can cut channels of varying width and depth. An example of a
laser cutter used to cut the channel 116 is an Epilog Mini 24, 35
Watt laser, manufactured by Epilog Laser of Golden, Colorado. FIG.
3B is a schematic cross-sectional view of the non-limiting
embodiment of the footwear insole 110 of FIG. 3A, having a channel
produced by the laser cutter of FIG. 3A, and FIG. 3C is a detail of
the schematic cross-sectional view shown in FIG. 3B, indicated by a
dashed circle 118. As illustrated in FIGS. 3B and 3C, the channel
116 may be cut completely through a top fabric layer 150 of the
footwear insole 110. In addition, the channel 116 may extend
partially into a bottom foam or gel layer 160.
[0047] Examples of settings on the Epilog Mini 24 laser that
allowed the laser to bum through essentially only the fabric layer
150 of an exemplary polyester knit lamination were 100% speed, 50%
power, 400 DPI (dots per inch) and 500 Hz. This exemplary polyester
knit lamination was comprised of a polyester knit fabric bonded to
a urethane film using a hot melt urethane adhesive, in which the
fabric laminate was molded to urethane foam using an open cast
urethane molding technique. For different materials that may make
up the fabric layer, a person having ordinary skill in the art
would be able to modify the settings of the laser depending upon
the different material properties of the fabric layer, such as
thickness, density, moisture content, and other properties. For
example, for a thicker fabric layer, a person having ordinary skill
in the art would be able to adjust the various settings, such as
power, of the laser in order to cut through the fabric layer.
[0048] FIG. 3D is an alternative schematic cross-sectional view of
a non-limiting embodiment of a footwear insole 110, having a
channel produced by the laser cutter of FIG. 3A, and FIG. 3E is a
detail of the alternative schematic cross-sectional view shown in
FIG. 3D, indicated by a dashed circle 119. As illustrated in FIGS.
3D and 3E, the channel 116 may be cut substantially into the top
fabric layer 150 of the footwear insole 110, such that the channel
116 does not extend into a bottom foam or gel layer 160. Further,
the channel may be cut to other various depths (not illustrated)
ranging from only partially cutting into a top fabric layer 150 to
both completely cutting through a top fabric layer 150 and
substantially cutting into a bottom foam or gel layer 160 of the
footwear insole 110. In each of these non-limiting embodiments, a
clean and neat tear line results when a consumer tears along the
predetermined channel.
[0049] FIG. 4A is a schematic plan view of a footwear insole 210,
according to a non-limiting embodiment of the present invention,
and FIG. 4B is a schematic cross-sectional view, along line B-B',
of the embodiment of a footwear insole 210 of FIG. 4A. The footwear
insole 210 includes a toe portion 220, a heel portion 230 and a
medial arch portion 240 interconnecting the toe and heel portions
220, 230. The insole 210 includes a top layer 250 of fabric and a
bottom layer 260 of cushioning material affixed to the top layer
250. However, the top layer 250 may also include multiple fabric
layers, and the bottom layer 260 may include multiple cushioning
material layers. A channel 216 cut by the laser cutter 112 is
situated in the toe portion 220 of the insole 210. FIG. 4A
illustrates three separate channel cuts 216 in the toe portion 220
of the insole 210. The channel 216 extends laterally and
curvilinearly across the top surface of the insole 210 and is
configured to correspond to a possible shoe size of a user. In
addition, as illustrated in FIG. 4B, the channel 216 may extend
approximately perpendicularly through the top layer 250 and
partially into the bottom layer 260. Optionally, a channel 226 cut
by the laser cutter 112 is situated in the heel portion 230 of the
insole 210. FIG. 4A illustrates separate channel cuts 226 in the
heel portion 230 of the insole 210. The channel 226 extends
laterally and curvilinearly across the top surface of the insole
210 with a direction of curvature opposite to a direction of
curvature of channel 216. A channel 236 cut by the laser cutter 112
is situated in the medial arch portion 240 of the insole 210 and
extends curvilinearly and longitudinally with respect to the insole
210. The insole 210 may include one or more channels 216 in the toe
portion 220, one or more channels 226 in the heel portion 230,
and/or one or more channels 236 in the medial arch portion 240.
Furthermore, with respect to channels 216, 226, 236, cutting the
channels 216, 226, 236 with the laser cutter 112 advantageously
produces a clean cut line in the fabric layer 250. In addition, if
the fabric layer 250 includes a polymer fabric, the laser beam 114
cauterizes the fabric layer 250, thereby preventing the fabric from
fraying at the cut line.
[0050] Further with respect to FIGS. 4A and 4B, the bottom foam
layer 260 may have a relatively low tear strength, e.g., less than
10 lbsf, for the user to tear the insole 210 cleanly and easily
along the channels 216, 226, 236. However, the bottom foam layer
260 may also have a sufficiently high modulus of elasticity, or
flexural modulus, in order to ensure that the insole 210 does not
permanently bend or wrinkle along the channels 216, 226, 236 when
slipped into an article of footwear.
[0051] FIG. 5A is a schematic plan view of a footwear insole 310,
according to another non-limiting embodiment of the present
invention. FIG. 5B is a schematic cross-sectional view of the
non-limiting embodiment of a footwear insole 310 of FIG. 5A along
line D-D'. FIGS. 5C and 5D are alternative, schematic
cross-sectional views of the non-limiting embodiment of a footwear
insole 310 of FIG. 5A along line C-C'. As in the embodiment shown
in FIG. 4A, the footwear insole 310 includes a toe portion 320, a
heel portion 330 and a medial arch portion 340 interconnecting the
toe and heel portions 320, 330. In addition, the footwear insole
310 includes a top layer 350 of fabric and a bottom layer 360 made
of a cushioning material. The insole 310 further includes a
laser-cut channel 316, which is situated in the toe portion 320 of
the insole 310 and runs laterally and curvilinearly across the top
surface of the insole 310. As illustrated in FIG. 5B, the channel
316 may extend through the top layer 350 and partially into the
bottom layer 360. FIG. 5A illustrates three separate channel cuts
316 in the toe portion 320 of the insole 310. In addition, the
insole 310 may further include a laser-cut channel 326, which is
situated in the heel portion 330 of the insole 310 and runs
laterally and curvilinearly across the top surface of the insole
310 with a direction of curvature opposite to a direction of
curvature of channel 316. FIG. 5A illustrates two separate channel
cuts 326 in the heel portion 330 of the insole 310. A laser-cut
channel 336 is situated optionally in the medial arch portion 340
of the insole 310 and runs curvilinearly and longitudinally with
respect to the insole 310. As discussed with respect to the
embodiment shown in FIGS. 4A and 4B, the insole 310 may include one
or more channels 316 in the toe portion 320, one or more channels
326 in the heel portion 330, and/or one or more channels 336 in the
medial arch portion 340 of the insole 310.
[0052] However, in contrast to the embodiment shown in FIGS. 4A and
4B, the insole 310 includes punctuations 317 in the bottom gel
layer 360. These punctuations may be produced by a die (not shown).
As illustrated in FIG. 5C, the punctuations 317 may extend
completely through the bottom layer 360 and run along the channels
316, 326, 336. Alternatively, as illustrated in FIG. 5D, the
punctuations 317 may extend substantially into but not completely
through the bottom layer 360 and run along the channels 316, 326,
336. In addition, as shown in FIG. 5A, the punctuations 317 are
separated from one another in the direction of the channels 316,
326, 336 by web elements 318. A spacing of the punctuations 317,
and thus a thickness of the web elements 318, may be adjusted such
that a user of the insole 310 may tear the insole 310 cleanly and
easily along the channels 316, 326, 336, while, at the same time,
the insole 310 does not bend or wrinkle along any intact channel in
the insole 310 when the insole 310 is slipped into an article of
footwear. The punctuations 317 and web elements 318 may be formed
of a variety of patterns including, but not limited to, circular,
square, rectangular, polygonal, and other shapes, and combinations
thereof. Further, punctuations as described in the present
invention include patterns that may otherwise be referred to as
perforations, serrations, cuts, punctures, notches, holes, slots,
etc., some of which are illustrated in FIG. 5A.
[0053] FIG. 6 is a flow chart of a method for manufacturing a
multilayer laminate footwear insole, according to a non-limiting
embodiment of the present invention. The method begins at step 400.
In step 410, a laminated footwear insole is assembled. The insole
has at least a top layer and a bottom layer. The top layer may
include one or more layers of fabric or film, and the bottom layer
may include one or more layers of foam or gel. In step 420, a
channel is cut into the top layer of the insole, e.g., by a laser
cutter. The channel corresponds to human foot sizes and extends
through the top layer and may extend partially into the bottom
layer. In step 430, a query is made as to whether another channel
is to be cut into the top layer of the insole, e.g., by a laser
cutter. If yes, then the method repeats step 420. If no, then in
method step 440, a query is made as to whether the bottom layer
should be punctuated in the channels. If no, then the method ends
at step 460. If yes, then the bottom layer is punctuated in the
channel(s) in step 450. The method then ends at step 460.
[0054] FIG. 7 is a flow chart of a method for reducing a dimension
of a multilayer laminate footwear insole, according to a
non-limiting embodiment of the present invention. The method begins
at step 500. In step 510, a query is made as to whether a toe
region of the insole has a channel corresponding to a desired foot
size. If no, then the method advances to step 530. If yes, in step
520, the insole is then torn by hand along the above-mentioned
channel in the toe region, after which the method advances to step
530. In step 530, a query is made as to whether a heel region of
the insole has a channel corresponding to the desired foot size. If
no, then the method advances to step 550. If yes, in step 540, the
insole is then torn by hand along the above-mentioned channel in
the heel region, after which the method advances to step 550. In
step 550, a query is made as to whether a medial arch region of the
insole has a channel corresponding to the desired foot size. If no,
then the method ends at step 570. If yes, then, in step 560, the
insole is torn by hand along the above-mentioned channel in the
medial arch region. The method then ends at step 570.
Alternatively, query 510 and step 520, query 530 and step 540, and
query 550 and step 560 may be re-ordered, as desired by a
consumer.
[0055] In a preferred non-limiting embodiment of the present
invention, a multilayer laminate footwear insole having a top layer
having a top surface and a bottom layer having a bottom surface,
the bottom layer including at least one cushioning layer, comprises
a channel in the insole, wherein the channel transects the top
layer of the insole, and one or more punctuations in the channel,
wherein the punctuation transects the bottom layer of the insole.
The multilayer laminate footwear insole may be a single
one-size-fits-all insole, which may be adjusted to various sizes
according to predetermined punctuated channels. Each channel may
have a preferred punctuation within the channel. In addition,
consumers may tear along each predetermined punctuated channel by
hand in order to adjust the insole size to fit within shoes.
[0056] The foregoing description discloses only non-limiting
embodiments of the present invention. Modification of the
above-disclosed multilayer laminate footwear insole, as well as
methods for making and using the same, which fall within the scope
of the invention, will be readily apparent to those of ordinary
