No. 6,665,883, entitled Oversock, issued Dec. 23, 2003.
BACKGROUND
[0002] 1. Field of the Invention
[0003] The present invention relates to a pocket or lodge slipper.
More particularly, the present invention relates to a waterproof
slipper with sufficient durability to allow the wearer to walk,
without shoes, in a damp or wet environment, without exposing the
underlying sock or foot to moisture or other elements of
nature.
[0004] 2. Description of the Related Art
[0005] Often, a person may wish to remove their outer footwear,
e.g., shoes or boots and wear only socks or go barefoot. In some
cases, the environment is not conducive to wearing only socks or
going barefoot, as the floor may be wet or dirty. One such
environment is a ski lodge.
[0006] The sport of skiing requires specialized clothing and
equipment designed to protect a skier in the harsh, winter
environment. Such equipment includes ski boots designed to protect
the skier's foot and ankle. Ski boots generally include a shell
formed from rigid plastic and an inner liner. The ski boot provides
several buckles to secure the skier's foot within the boot. The
boot includes a foot portion and a leg portion, the leg portion
angled slightly toward the toe end of the foot portion making
walking in the boots difficult.
[0007] During a day of skiing, it is common to go into the ski
lodge to eat, warm up, or simply relax. At this time, skiers may
prefer to remove their ski boots; however, in most ski lodges
removing a skier's boots is not practical. The floor of the lodge
is usually wet and dirty as other skiers walk into the lodge
wearing snow-covered boots and outer clothing.
[0008] Typically, it is impractical to remove ski boots in a ski
lodge and put on a different pair of shoes or boots, as ski lodges
are not typically equipped with lockers of sufficient size to
accommodate ski boots, and, moreover, changing into shoes once
inside the ski lodge is time consuming and cumbersome. To allow for
such a change into shoes, a skier must initially bring outer
footwear, e.g., shoes or conventional boots into the lodge and
store the footwear in a locker. When changing, the skier must
retrieve the footwear from the locker, change, and either carry
their ski boots or leave them outside of the unaccommodating
locker. When the skier returns to the locker to change back into
ski boots and replace the alternative footwear, e.g., shoes or
boots in the locker, he typically must again pay to lock the
locker. Not only is the process of changing from ski boots into,
e.g., shoes or boots cumbersome and time consuming, but also shoes
or boots may not provide the desired level of comfort. Moreover,
bringing shoes to a ski lodge can prove to be problematic, as ski
lodges are typically located on the summit of the mountain or hill
being skied and, therefore, shoes brought to the lodge must,
undesirably, be carried on the ski lift.
[0009] What is needed in the art is a foot covering that is
waterproof, lightweight, breathable and comfortable.
SUMMARY
[0010] The present invention provides a foot covering in the form
of a pocket or lodge slipper that allows outer footwear, e.g.,
shoes or boots to be removed and, with the covering of the present
invention in place, the conventional sock and/or foot will be
protected from dirt, moisture, and other elements of nature such as
thorns, rocks, splinters, etc. The slipper may be formed at least
in part from elastic material which is stretchable to fit over a
conventional sock. The slipper may also be formed at least in part
from a rubberized material. The slipper may be flexible and
foldable or rollable into a small volume to be carried in a pant or
coat pocket, for example. Alternatively, the slipper may be tightly
rolled or folded and carried in a small package such as a pouch or
nylon bag.
[0011] The slipper may include a body with a waterproof sole
attached thereto. In one embodiment, a mesh portion is connected to
the body and advantageously allows breathability and comfort to the
wearer's foot. Alternatively, the mesh portion can be replaced with
a non-porous material to retain warmth within the slipper. In yet
another alternative embodiment, the slipper may have a flap which
may be selectively placed to cover the mesh material with a
warmth-retaining material. The material of the waterproof sole is
durable to prevent tearing and enhance reusability. In one
exemplary embodiment, the slipper includes a non-slip, texturized
surface on the sole thereof. The waterproof sole may extend a
distance up the side of the body to facilitate protection of a
wearer's foot and/or sock from various elements, such as deep water
puddles. The waterproof sole may be formed of rubber with a
thickness greater on the bottom surface thereof than the thickness
of the waterproof material on the sides of the body.
[0012] The slipper may include an elastic band portion defining an
opening for entry of the wearer's foot. The insole portion of the
slipper may be made of a similar material as the body of the
slipper, i.e., knit, synthetic, or cotton material. The insole
portion may be separately applied to the slipper by gluing or
stitching the insole portion to the body. Alternatively, the insole
portion may be integrally formed with the body. The insole portion
may include a composite structure constructed of a tough material,
such as Kevlar, thin plastic, stainless steel, etc. The composite
structure may be glued to the body underneath the insole portion or
may be held in place after the insole portion is attached to the
body. Alternatively, the composite portion could be slid into the
slipper on top of the insole portion and held in place by the
weight of the wearer.
[0013] The slipper advantageously allows for removal of outer
footwear, without fear that a wet and/or dirty floor, e.g., a ski
lodge floor, will foul the underlying socks or feet, while
simultaneously providing a comfortable slipper which is easily
transported.
[0014] The slipper also advantageously allows for removal of outer
footwear without fear that a dangerous environment, for example, an
environment containing stones and thorns, will harm the feet, while
simultaneously providing a comfortable slipper which is easily
transported.
[0015] In one form thereof, the present invention provides a
slipper for use in shielding an individual's foot from moisture and
other elements when the individual is not wearing outer footwear,
the slipper including a body having a lower portion, a side
portion, and an upper portion; and a flexible sole, the sole
attached to the body proximate the lower portion, the sole attached
to and covering at least a portion of the side portion, the sole
extending at least partially up the side portion towards the upper
portion, the sole including a varying thickness.
[0016] In another form thereof, the present invention provides a
method of shielding an individual's foot from moisture and other
elements when the individual is not wearing outer footwear,
including providing a slipper having a body having a lower portion,
a side portion, and an upper portion; and a flexible sole, the sole
attached to the body proximate the lower portion, the sole attached
to and covering at least a portion of the side portion, the sole
extending at least partially up the side portion towards the upper
portion, the sole including a varying thickness; placing the foot
into the slipper; and placing an exterior surface of the sole on a
moisture contaminated or debris-encumbered surface.
[0017] In yet another form thereof, the present invention provides
a method of protecting a skier's foot from moisture and other
elements in a ski lodge, the method including the steps of
providing a slipper including a body having a lower portion, a side
portion, and an upper portion; and a flexible sole separate from
the body, the sole attached to the body proximate the lower
portion; providing a receptacle for holding the slipper; inserting
the slipper into the receptacle; storing the slipper in the
receptacle while skiing; removing the slipper from the receptacle;
placing the individual's foot into the slipper; and moving about
the ski lodge with the slipper positioned on the skier's foot.

DETAILED DESCRIPTION
[0031] Referring to FIG. 1, pocket or lodge slipper 10 is shown in
perspective view. Slipper 10 includes body 12 including upper
portion 34, side portion 35, and bottom portion 36 (FIG. 3, hidden
from view by sole 14 in FIG. 1) as well as interior 38. In one
embodiment, bottom portion 36 forms insole 20, described below.
Upper portion 34 may be used to facilitate capture and holding of a
wearer's foot within slipper 10. Body 12 is formed of a knit sock
or any other suitable material providing one or both of the
advantages of elasticity and comfort. For example, body 12 may be
formed of a synthetic material or a natural material, such as
cotton. In one embodiment, body 12 is formed of a conventional
sock. Body 12 may be formed as a breathable fabric which is highly
elastic to conform to a wearer's foot. Bottom portion 36 of body 12
may be substantially covered with and in continuous contact with
sole 14, or, alternatively, bottom portion 36 of body 12 is
integrally formed with sole 14. Sole 14 is a waterproof covering
which, in one exemplary embodiment, is made of rubber, latex, soft
plastic, or other suitable equivalent material which provides
durability to slipper 10 and protection to a wearer's foot and/or
sock while simultaneously providing adequate traction on wet
surfaces. In one embodiment, sole 14 is located over the bottom of
the wearer's foot when slipper 10 is worn and, generally, is the
portion of slipper 10 in contact with the floor. In one alternative
embodiment, sole 14 is texturized. Sole 14 may extend upwardly on
side portions of body 12, upward from a bottom portion thereof.
[0032] Referring to FIGS. 4-7, in one embodiment, sole 14 may be
constructed as a separate piece from body 12 (FIG. 1) and formed of
rubber or equivalent material. Rubber sole 14 is attached to body
12 (FIG. 1) by, for example, gluing, stitching, or any other
suitable fastener, or any combination thereof. For example, sole 14
may be attached to body 12 along side portions thereof with
fasteners 25, shown in FIG. 5. In one embodiment, fasteners 25
comprise stitching. Sole 14 may extend from toe portion 21 to heel
portion 23 to substantially and completely cover the bottom portion
of body 12 of slipper 10.
[0033] Referring again to FIGS. 4-7, sole 14 may include two
general portions defined by bottom portion 30 and side portion 32.
In an exemplary embodiment, bottom portion 30 may have a thickness
between approximately 1.5 millimeters (mm) (.about.59 mils) and 2
mm (.about.79 mils), or, alternatively, between approximately 0.5
mm and 3 mm. The durability of slipper 10 not only relates to the
material from which sole 14 is constructed but also to the
thickness of the material from which sole 14 is constructed. The
durability and thickness of sole 14 of slipper 10 are directly
related, as increased thickness yields increased durability of
slipper 10. However, a thicker sole 14 of slipper 10 may be more
difficult to fold or roll and keep compact when stored. Therefore,
the thickness may be limited to allow the slipper to be stored in a
conventional pocket, as described below. An exemplary thickness of
the material of bottom portion 30 of sole 14 of slipper 10 to
maintain durability and flexibility is in the range of 10-30 mils.
In an alternative exemplary embodiment, sole 14 is covered with or
constructed from a stretchable and durable material having a
lamellar thickness in a range of 2-60 mils. In another exemplary
embodiment, sole 14 is covered with or formed of a material having
a lamellar thickness in the range of 2-40 mils. In a further
exemplary embodiment, sole 14 is covered with or formed of a
material having a lamellar thickness in the range of 10-20 mils. In
a still further exemplary embodiment, the thickness of material is
in the range of 20-60 mils.
[0034] The thickness of sole 14 may taper from bottom portion 30 to
side portion 32. Side portion 32 may have a thickness between
approximately 0.5 mm and 1 mm. Bottom portion 30 and side portion
32 provide a large degree of flexibility to slipper 10 because of
the material and thickness of that material. For the purposes of
this document, the term "flexible" means that slipper 10 may be
flexible enough to permit slipper 10 to be rolled or folded into a
compact structure, as described further hereinbelow and shown in
FIGS. 9 and 11. Side portion 32 may extend upwards away from bottom
portion 30 by a distance of approximately 0 centimeters (cm) to 2.5
cm. In one embodiment, the distance is approximately 0 cm to 1.5
cm. In another embodiment, the distance is approximately 1.5 cm to
2.5 cm. In an alternative embodiment, side portion 32 may extend
further up and cover at least a portion of side portion 35 of body
12 to facilitate use in an environment with deep water puddles or
other standing water. Additionally, sole 14 may include a plurality
of creases, grooves, and/or thinner portions (not shown) in bottom
portion 30 to facilitate folding slipper 10, as described
below.
[0035] In an alternative embodiment, sole 14 may be formed by
dipping a foot form into uncured liquid latex. The liquid latex may
extend up the side portions of the foot form a desired distance, as
described above. Once the latex is cured, sole 14 is removed from
the foot form and attached to body 12 via any suitable method, as
described above.
[0036] In another embodiment, sole 14 may be constructed using a
technique wherein body 12 is first placed on a foot form, such as a
last. Body 12 includes a bottom portion as well as upwardly
extending side portions as seen in FIGS. 1 and 2. The bottom
portion of body 12 refers to the portion of body 12 that would, in
use, if no sole 14 was secured to body 12, contact the floor. Body
12 and the foot form are dipped into a material, such as uncured
liquid latex, to a depth such that the bottom portion of body 12 is
fully submerged. Latex flows around body 12, thereby embedding the
material of body 12 in liquid latex. In one embodiment, the liquid
latex covers the bottom portion and a portion of the upwardly
extending side portions of body 12 approximately 1.5 cm to 2.5 cm
upward from the bottom portion. In another embodiment, the liquid
latex may only extend just above the bottom portion of body 12,
i.e., approximately 0 cm to 1.5 cm. In an alternative embodiment,
the liquid latex may extend further up the side portions of body 12
to facilitate use in an environment with deep water puddles or
other standing water. Finally, the liquid latex coating will cure
to form sole 14 and body 12 is removed from the foot form.
[0037] In another alternative embodiment, sole 14 may be
constructed from a single piece of material cut out to the desired
shape and attached to body 12. For example, sole 14 may be
constructed of a single piece of latex rubber prefabricated into
large sheets and cut out to the desired shape to attach to body
12.
[0038] Treads 22 (FIGS. 4, 5, 7) may be imparted to sole 14 by
pressing sole 14 and the foot form against a mold, if sole 14 is
formed of dipped latex rubber. Sole 14 may be imprinted with the
tread pattern before the latex is completely cured, or,
alternatively, treads 22 may be formed after the latex is
completely cured, e.g., by removing or roughening a portion of sole
14 via a cutting instrument other suitable process, as is
well-known in the art. Also, treads 22 may be formed after the
latex is cured by adding texturized pieces of latex or rubber and
gluing or otherwise affixing the pieces to sole 14. In a further
alternative embodiment, treads 22 may be formed by texturizing the
surface of sole 14 as part of the dipping and curing process by,
for example, pressing a pattern mold against the uncured latex
which imparts a texturized surface thereto. Treads 22 may be formed
in the rubber material of sole 14 and be configured in any number
of configurations to enhance traction of slipper 10, as is
well-known.
[0039] Slipper 10 may have the shape of a conventional sock,
including body 12 and a leg portion (not shown) extending upwardly
therefrom and terminating at a point along a wearers leg. Slipper
10 may be formed as a tube sock, or may include a shaped heel
defined by heel portion 23 of sole 14. The length of the leg
portion may be any suitable length including, e.g., relatively
short, stopping just short of the ankle, i.e., extending
approximately 2.5 cm (1 in.) from body 12, or relatively long,
extending approximately 15 cm (6 in.) from body 12 to mid-calf. As
illustrated in FIG. 1, slipper 10 is sized to fit over a
conventional sock or a bare foot. Slipper 10 may be individually
sized or provided in several sizes, each encompassing a range of
three or four shoe sizes, similar to the sizing of a conventional
sock.
[0040] Slipper 10 is at least partly constructed from a waterproof
material to protect a sock or foot from being dampened by wet
floors. Further, slipper 10 may be elastic and stretchable to fit
securely about a sock and/or fit the contour of the wearer's foot.
In one exemplary embodiment, slipper 10 is sufficiently durable to
allow for repeated use and cleaning if necessary. Slipper 10 may be
washable to facilitate multiple uses thereof. In further
embodiments of the present invention, slipper 10 is designed as a
single use item.
[0041] Slipper 10 is conveniently portable, being flexible so that
it may be folded and stored in a small package. This allows the
user to carry slipper 10 in a package or a conventional pocket of
an article of clothing such as a pair of pants or a coat,
eliminating the need to retrieve slipper 10 from a locker, for
example. For the purposes of this document, "conventional pocket"
means a pocket found in an article of clothing as originally
manufactured, e.g., a front pocket of a conventional pair of
pants.
[0042] In use, slipper 10 may be tightly rolled, as shown in FIG.
9, or folded, as shown in FIG. 11, and put in a package, for
example, a small pouch or nylon bag, shown in FIG. 10. The rolled
up slipper 10 may be secured in that manner with any suitable
fastener, such as a hook and loop fastener with an extra wide tab
at one end of the fastener to facilitate fastening the fastener, a
clasp with a clip structure, a snap mechanism, a pull string with
stopper attached thereto, or a buckle or belt structure. Referring
to FIG. 10, once secured in a rolled up position, slipper 10 may be
inserted into carrying structure or package or receptacle 40, with
the longitudinal length of rolled up slipper 10 perpendicular to
the bottom of the package, as shown by solid lines in FIG. 10, and
then rotated 90.degree. to ensure that the rolled up slipper 10
lays flat with the bottom of the package, as shown by dashed lines
in FIG. 10. Package 40 may be closed with a hook and loop fastener
foldover structure (not shown) or a pull string with stopper (not
shown).
[0043] Alternatively, slipper 10 may be folded either once or twice
and then inserted into the package. Creases or grooves (not shown)
in bottom portion 30 of sole 14 facilitate folding of slipper 10 in
this manner. To enhance sliding slipper 10 into the package, a
small, semi-firm piece of plastic may be bent around slipper 10 and
then the entire assembly is inserted into the package. The plastic
facilitates sliding of slipper 10 within the package.
[0044] Sole 14 of slipper 10 may be constructed from any suitable
material possessing the above described characteristics. Such
materials include latex, rubber, vinyl, synthetic nitrile, or a
waterproof, breathable material such as polytetrafluoroethylene
commonly known by the trade name GORE-TEX. All of the above
materials are flexible so that slipper 10 is easily foldable or
rollable to be stored in a small, portable package.
[0045] Slipper 10 may be conveniently sold in vending machines or
in gift shops located in, e.g., a ski lodge or campground.
Materials of construction such as, e.g., latex, rubber, vinyl, or
synthetic nitrile are relatively inexpensive, but nevertheless are
sufficiently durable and abrasion resistant so that slipper 10 may
be used throughout an entire day or more of skiing or other
activity. These materials have varying degrees of elasticity and
stretchability with latex and rubber being more elastic than
synthetic nitrile and vinyl. When formed of materials such as
latex, rubber, vinyl, or synthetic nitrile, slipper 10 may be sold
at a sufficiently low price to facilitate marketing slipper 10 as a
single use, i.e., disposable item.
[0046] When sole 14 of slipper 10 is constructed from GORE-TEX or
other similar material, slipper 10 is slightly more expensive and
more durable. These more expensive versions of slipper 10 are meant
for more long-term use relative to the aforementioned materials of
construction and may be sold in, e.g., gift shops and sports
stores, in addition to various on-site facilities.
[0047] Referring now to FIGS. 1 and 3, slipper 10 can include band
18 attached to body 12 around a top portion thereof. Band 18
includes, in one exemplary embodiment, an elastic material, thereby
further enhancing the elasticity and comfort of slipper 10. Band 18
may be stitched to body 12. Band 18 encompasses a portion of
slipper opening 24 through which a wearer inserts his or her foot.
The elasticity of band 18 facilitates maintaining slipper 10 on the
wearer's foot during use.
[0048] Slipper 10 includes mesh portion 16 disposed near toe
portion 21 of slipper 10. Mesh portion 16 is made of a lightweight
and thin, e.g., nylon, material which allows a wearer's foot to
breath, thereby adding enhanced comfort and wearability. Mesh
portion 16 extends laterally across slipper 10 to provide enhanced
stability and comfort and may be stitched to body 12. Mesh portion
16 advantageously provides circular openings having a diameter of
approximately 3 mm to 5 mm to promote efficient evaporation of
moisture and release of heat from a wearer's foot during use.
Alternatively, mesh portion 16 advantageously provides polygonal
openings having at least one dimension of approximately 1 mm to 5
mm to promote efficient evaporation of moisture and release of heat
from a wearer's foot during use.
[0049] Alternatively, mesh portion 16 may be replaced or covered
with a material which facilitates keeping warmth within slipper 10
or with a material similar to the remainder of body 12. For example
as shown in FIG. 2, slipper 10 may include flap portion 28 which is
substantially thicker than mesh portion 16 and is non-porous to
keep heat within slipper 10. Flap portion 28 may be selectively
moved from a stowed position, e.g., a rolled-up position as shown
in FIG. 2, to cover mesh portion 16 to keep heat within slipper 10.
Flap portion 28 may be maintained in the stowed position via a hook
and loop fastener arrangement, snaps, or a buckle arrangement. Flap
portion 28 may be removably or permanently attached to upper
portion 34 via stitching, gluing, or other attachment. Flap portion
28 may be selectively attached around mesh portion 16 via a hook
and loop fastener, snaps, or other attachment. Flap portion 28 may
unroll in two directions, i.e., towards mesh portion 16 and towards
band 18, which allows flap portion 28 to extend up the wearer's
ankle to keep the wearer's ankle warm. Alternatively, flap portion
28 may replace mesh portion 16 and be permanently attached to
slipper 10 to keep heat within slipper 10.
[0050] In an alternative embodiment shown in FIG. 8, slipper 10 may
include strap 17 extending laterally across a wearer's foot in
place of or in combination with mesh portion 16. Strap 17 may be
positioned proximate to a user's ankle to enhance stability of
slipper 10 while maintaining the efficient evaporation of moisture
and release of heat because of the lack of fabric 13 in upper
portion 34 beyond strap 17 towards the toes of the user. The strap
may be formed of nylon, elastic, a knit material or any other
suitable material which enhances stability, comfort, and ease of
use. Strap 17 may be used to facilitate capture and holding of a
wearer's foot within slipper 10. Strap 17 may be permanently
affixed on both ends 17a and 17b thereof to body 12 by, e.g.,
gluing or stitching. Alternatively, strap 17 is permanently affixed
on one end 17a or 17b and removably attached at the other end 17b
or 17a via a hook and loop fastener, a snap fastener, or any other
suitable fastener. Strap 17 may be removably attached at both ends
17a and 17b to facilitate complete removal of strap 17 when not in
use.
[0051] Referring now to FIG. 3, slipper 10 may include insole 20.
Insole 20 may include thicker, but otherwise identical or similar,
material as body 12. In one exemplary embodiment, insole 20 is sewn
into slipper 10. In another embodiment, insole 20 is glued into
slipper 10 by either applying glue around the bottom circumference
of insole 20 or the entire bottom surface of insole 20 and then
affixing insole 20 to body 12. Alternatively, insole 20 may be a
later added structure to facilitate removal of insole 20 after
insole 20 has become worn and needs to be replaced. In addition,
insole 20 may be integral or formed with body 12.
[0052] In one embodiment, insole 20 may include a composite insole
which is constructed of a tough material that advantageously is
less penetrable to such objects as thorns, rocks, splinters, or
other objects encountered in a particular environment in which
slipper 10 is worn, for example, in a camping environment. The
composite insole may be constructed of Kevlar, a tough and thin
plastic material, a stainless steel plate or lining, or any other
durable and tough material which prohibits penetration
therethrough. The composite insole may be placed underneath insole
20 and held in place by insole 20 attached to body 12.
Alternatively, the composite insole may be glued directly to body
12 or to insole 20 or the composite insole may be a later added
structure to facilitate removal of the composite insole if the
composite insole is no longer needed or becomes worn and needs
replaced. The composite insole may be a single piece, separate
pieces, or a creased single piece of material, the latter two of
which facilitate folding or rolling of slipper 10 when not in
use.
[0053] Referring now to FIG. 4, sole 14 may include a plurality of
treads 22. Treads 22 advantageously provide enhanced traction while
slipper 10 is in use.
[0054] In operation, a user inserts their foot through slipper
opening 24 into slipper 10. Sole 14 provides a waterproof and
durable covering to prevent any liquid on a floor surface from
soiling the user's sock or foot and to prevent any debris from
harming the user's foot. Body 12, sole 14, mesh portion 16, and
band 18 cooperate to provide enhanced stability, comfort and
wearability while simultaneously allowing efficient evaporation of
moisture and escape of heat. Treads 22 on sole 14 facilitate
prevention of slipping and falling during use.
[0055] Although primarily described throughout with reference to a
ski lodge environment, slipper 10 may be used during other
activities such as camping, driving, plane riding, or biking,
wherein such activities involve some interaction with elements such
as mud, water, or other wet or debris-filled areas.
[0056] While this invention has been described as having exemplary
designs, the present invention can be further modified within the
spirit and scope of this disclosure. This application is therefore
intended to cover any variations, uses, or adaptations of the
invention using its general principles. Further, this application
is intended to cover such departures from the present disclosure as
come within known or customary practice in the art to which this
invention pertains and which fall within the limits of the appended
claims.
