Description
[0001] This application claims the benefit of provisional
application 60/491,230, filed Jul. 31, 2003.
BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] The present invention relates to protective coverings for
shoes having spikes, cleats, taps or other protrusions extending
outward from the bottom of the shoe, and more particularly to a
covering comprised of a front part that wraps around the front of
the shoe and keeps protrusions on the front of the shoe from
touching the ground, and a back part that fits over the heel of the
shoe for keeping heel protrusions off the ground.
[0004] 2. Background Information
[0005] In many athletic activities, participants wear special shoes
that have spikes, cleats, taps or other protrusions extending
outward from the bottom of the shoe. Examples of such activities
include track and field, soccer, American football, baseball, golf,
tap dancing and many other sports.
[0006] Generally, the protrusions (especially, spikes, cleats and
taps) are made from a metal, but they can also be made of hard
plastic or rubber, or of other materials. Regardless of the
composition of the protrusions, several problems are presented by
such shoes. One problem is that the protrusions wear down quickly
when a person wearing the shoes walks on a hard surface such as
asphalt, concrete, dirt, metal or wood. Oftentimes, athletes will
walk on the sides of their feet, on their heels or even in bare
feet in an effort prevent the spikes, cleats or taps from
contacting the hard surface and suffering wear and tear.
[0007] Another problem, and one that is sometimes exacerbated by
the first problem, is that it can be difficult to walk safely on
hard surfaces when one is wearing shoes having spikes or other
protrusions. The protrusions can cause the wearer to slip or they
can catch on a surface and trip the wearer. Still another problem
is that a floor or other walking surface can be damaged by the
protrusions.
[0008] In view of these problems, there are many examples of
protective shoe coverings in the prior art that attempt to reduce
these problems in various ways. One approach is to provide a
protective sole that covers the protrusions extending from the
athletic shoe. For example, U.S. Pat. No. 5,722,189 discloses a
hard sole that covers the cleats on golf shoes. A problem with this
type of athletic shoe covering is that a custom designed sole is
required for each style of shoe, size of shoe or cleat pattern on
the shoe. Another approach is to provide a slip-on cover that
slides over part or all of the athletic shoe. For example, U.S.
Published Patent Application No. 2004/0035026 discloses a
pocket-like covering for spiked track shoes that slips over the
front of the shoe. Coverings of this type are hard to put on
because they can catch on the spikes or other protrusions.
[0009] What is needed is a protective covering for athletic shoes
that reduces the problems associated with shoes having protrusions
from the sole and that will fit many styles and sizes of athletic
shoes while being quick and easy to put on.
BRIEF SUMMARY OF THE INVENTION
[0010] Briefly, the present invention is a covering for shoes
having spikes, cleats, taps or other protrusions extending from the
soles of the shoes. The covering comprises a toe member and a heel
member. The toe member is adapted for wrapping around the front
part of the shoe having a sole from which one or more of the
protrusions extend, and comprises a right flap, a right strap, a
left flap, a left strap and a first bottom member. The right flap
comprises a piece of material that wraps around at least a part of
the right front side of the shoe and the right strap comprising an
elongated piece of material that extends from the right flap.
Similarly, the left flap comprises a piece of material that wraps
around at least a part of the left front side of the shoe and the
left strap comprises an elongated piece of material that extends
from the left flap. The right flap and the left flap attach to each
other with a first fastener to secure the toe member around the
shoe. The first bottom member covers at least a part of the sole
and prevents at least some of the protrusions from contacting a
walking surface when the toe member is wrapped around the shoe.
[0011] The heel member is adapted for positioning around the back
part of the shoe and comprises a cup portion and a second bottom
member. The cup portion comprises a piece of material that fits
around the back part of the shoe and the second bottom member
covers at least a part of the sole and can prevent some protrusions
from contacting the ground. A second fastener is used to attach the
right strap of the toe member to the heel member and a third
fastener is used to attach the left strap of the toe member to the
heel member to help in securing the heel member to the shoe. The
heel member is a separate piece from the toe member when the right
and left straps are not attached to the heel member.

DETAILED DESCRIPTION OF THE INVENTION
[0016] FIG. 1 illustrates a protective covering for a shoe 10
comprised of a toe member 14 and a heel member 18. The shoe 10 has
a plurality of protrusions 20, such as spikes, cleats or taps,
extending downward from the sole 21 of the shoe 10. The shoe 10,
which is not part of the present invention, also includes a toe
section 22, a heel section 23 and an opening 57. The sole 21
extends along the length of the shoe 10 underneath the toe section
22 and the heel section 23. In FIG. 1, a protective covering for a
left shoe is illustrated, but the protective covering for a right
shoe is analogous to the left shoe covering, and is basically its
mirror image.
[0017] The toe member 14 comprises a right flap 24, a right strap
26, a left flap 28, a left strap 30 and a front bottom member 32.
The left flap 28 wraps around the left front side of the shoe 10
and the right flap 24 wraps around the right front side of the shoe
10 and over part of the left flap 28 (as shown in FIG. 2). The
front bottom member 32 covers at least part of the sole 21 at the
front of the shoe 10. The front bottom member 32 covers less than
one hundred percent of the sole 21 because the member 32 doesn't
extend backward underneath the heel section 23. The front bottom
member 32 covers the protrusions 20 that extend from the sole of
the shoe 10 underneath the toe section 22. After the toe member 14
is properly positioned around the shoe 10, the right flap 24 and
the left flap 28 are fastened together with a fastener. In the
preferred embodiment, the fastener comprises a hook and loop
fastener such as Velcro.RTM. brand hook and loop fastener. However,
other fasteners, including snaps, buttons, zippers or laces, can
also be used to secure the flaps 24 and 28 together.
[0018] In FIG. 1, a patch of hook fasteners 36 is positioned along
an edge of the right flap 24 and a patch of loop fasteners 38 is
positioned along an edge of the left flap 28. When the right flap
24 is positioned over the left flap 28, the hook fasteners 36
engage the loop fasteners 38, thereby securing the right flap to
the left flap. The right strap 26 has a patch of loop fasteners 40
positioned at its end, and the left strap 30 has a patch of loop
fasteners 42 positioned at its end.
[0019] The heel member 18 comprises a cup portion 46 and a back
bottom member 48. The cup portion 46 comprises a piece of material
that fits around the heel 23 of the shoe 10. The back bottom member
48 is attached to the cup portion and covers at least part of the
sole 21 at the back of the shoe 10. The back bottom member 48
covers less than one hundred percent of the sole 21 because the
member 48 doesn't extend forward underneath the toe section 22. The
back bottom member 48 covers the protrusions 20 that extend from
the sole of the shoe 10 underneath the heel section 23, if there
are any such protrusions. One or more fasteners are positioned on
the cup portion 46 to provide a means for attaching the left strap
30 and the right strap 26 to the heel member 18. In the preferred
embodiment, most of the outside surface of the cup portion 46 is
covered with hook fasteners 50, such as Velcro.RTM. brand hook
fasteners. However, other fasteners, including snaps, buttons,
zippers or laces, can also be used to secure the straps 26 and 30
to the heel member 18. An ankle strap 54 extends from the right
side of the cup portion 46. One or more fasteners are positioned on
the ankle strap 54 to provide a means for attaching the ankle strap
54 to the heel member 18. In the preferred embodiment, the ankle
strap 54 has a patch of loop fasteners 56, such as Velcro.RTM.
brand loop fasteners, positioned at its end for attachment to the
hook fasteners 50, but other types of fasteners can be used.
[0020] FIG. 2 illustrates the protective covering positioned around
the shoe 10. In the preferred embodiment, the toe member 14 is
wrapped completely around the front part of the shoe 10, forward of
the opening 57 in the shoe 10 where the ankle of a person wearing
the shoe 10 would extend out of the shoe. The left flap 28 is
wrapped snuggly over the top of the shoe 10 with the right flap 26
wrapped over the top of the left flap 28 and securely fastened to
the left flap 28 by the fasteners 36 and 38. A front protective
sole 60 is attached to the outside of the toe member 14, adjacent
to the bottom member 32. A pair of cuts 61 are made in the left
flap 28.
[0021] The heel member 18 is positioned snuggly around the back
section 23 of the shoe 10, behind the opening 57. The left strap 30
is attached to the cup portion 46 by the fasteners 42 and 50.
Similarly, the right strap 26 is attached to the cup portion 46 by
the fasteners 40 and 50, but this can't be seen in FIG. 2. The
ankle strap 54 is shown in an unattached orientation, but in use,
it would be pulled over the ankle of a person wearing the shoe 10
and attached to the cup portion 46 using the fasteners 56 and
50.
[0022] In alternative embodiments, the ankle strap 54 can be
eliminated and the heel member 18 is held in place using only the
straps 26 and 30 and/or the tight fit of the heel member 18 around
the shoe 10. A rear protective sole 62 is attached to the outside
of the heel member 18, adjacent to the bottom member 48. On the
left strap 30, a stitch pattern 63 is visible on the outside of the
strap 30 showing the stitches that hold the patch of loop fasteners
42 in place. Also, FIG. 2 illustrates that the toe member 14 and
the heel member 18 do not cover one hundred percent of the sole 21
(shown in FIG. 1) of the shoe 10, because there is a gap between
the front protective sole 60 and the rear protective sole 62 when
the members 14 and 18 are positioned around the shoe 10.
[0023] FIG. 3 illustrates the heel member 18 in more detail. In the
preferred embodiment the cup portion 46 comprises a single piece of
material having a cup shape that fits around the heel of the shoe
10. Two sections of the cup portion 46, a right section 66 and a
left section 68 extend underneath the back bottom member 48 and
meet at an intersection 70. The intersection 70 is a cut in the
material that extends back approximately to a curve 72 in the cup
portion 46. An additional series of cuts (not shown) are made in
the right section 66 and the left section 68 in a radial pattern.
The cuts (approximately six to eight cuts) are approximately one
inch in length and extend from the curve 72 inward towards the
intersection 70 in a semicircle pattern. The cuts help the material
to be shaped into the cup-shape of the cup portion 46 by removing
small amounts of material from between the cuts.
[0024] In the preferred embodiment, the cup portion 46 comprises a
strong flexible material that can be stretched without losing its
original shape, such as neoprene. Preferably, the cup portion 46
comprises approximately three millimeter thick neoprene and the
back bottom member 48 comprises approximately seven millimeter
thick neoprene. The neoprene has a nylon covering on both sides.
After the radial cuts are made (during die cutting) in the right
section 66 and the left section 68, an adhesive that will form
neoprene to neoprene bonds, such as a contact cement like
Weldwood.TM. brand contact cement, is applied to the radial cuts so
that the neoprene that was separated by the cuts is rejoined, and
the material is folded into the cup shape. Similarly, the adhesive
is used to join the right section 66 and the left section 68 along
the intersection 70.
[0025] In the preferred embodiment, the rear protective sole 62
comprises approximately two to three millimeter thick thermoplastic
rubber, such as Dynaflex.RTM. brand thermoplastic rubber. The rear
protective sole 62 is attached to the outside of the cup portion 46
using an adhesive, such as Loctite.RTM. 401 brand ethyl
cyanoacrylate adhesive. A primer, such as Loctite.RTM. 770 brand
primer is applied to the protective sole 62 first to facilitate
formation of the thermoplastic rubber to nylon bond, and is allowed
to dry. Then the adhesive is applied on top of the dried primer and
the rear protective sole 62 is immediately pressed against the
bottom of the right section 66 and the left section 68, thereby
attaching the rear protective sole 62 to the heel member 18.
[0026] The back bottom member 48 is attached to the cup portion 62
above the right section 66 and the left section 68, using an
adhesive that forms nylon to nylon bonds (because the neoprene is
covered with nylon), such as 3M Scotch-Grip Plastic Adhesive
1099.TM.. The specific thickness and composition of the back bottom
member depends on the type and size of the protrusions 20.
[0027] Earlier in the assembly process, usually after die cutting
the cuts in the neoprene but before shaping the cup portion 62, the
patch of the hook fasteners 50 is sewn onto the outside of the cup
portion 62, so as to cover approximately all of the outside surface
area of the cup portion 62, except for the strap 54, the right
section 66 and the left section 68. The patch of the loop fasteners
56 are sewn onto an inside surface of the ankle strap 54.
[0028] FIG. 4 illustrates the toe member 14 in more detail. In the
preferred embodiment the right flap 24 and the right strap 26
comprise a single piece of material. Similarly, the left flap 28
and the left strap 30 comprise a single piece of material. During
manufacturing, the flaps 24 and 28 are joined together to form a
single piece of material that can be wrapped around the front part
of the shoe 10. A V-shaped space 74 exists between right flap 24
and the left flap 28. A right portion 76 of the flap 24 is
positioned underneath the front bottom member 32, and a left
portion 78 of the flap 28 is positioned underneath the front bottom
member 32. The right portion 76 and the left portion 78 meet at an
intersection 80.
[0029] The intersection 80 is the interface where the right portion
76 and the left portion 78 are joined. The intersection 80 extends
all the way up to the space 74 so that the right portion 76 is
separated from the left portion 78 all the way up to the space 74.
Additional cuts are made in the right portion 76 and in the left
portion 78 to facilitate shaping the toe member 14 into a shape
that conforms to the shoe 10, by removing small amounts of material
from between the cuts. Preferably, approximately five cuts are made
in the left portion 78 at forty-five to ninety degree angles to the
intersection 80, and similar cuts are made in the right portion 76.
The cuts can extend into the left flap 28 as is indicated by the
cuts 61 shown in FIG. 2 to help the left flap 28 curve around the
shoe 10.
[0030] In the preferred embodiment, the right flap 24, the left
flap 28 and the straps 26 and 30 are comprised of a strong flexible
material that can be stretched, such as neoprene. Preferably, the
neoprene is approximately three millimeters thick. The front bottom
member 32 comprises approximately seven millimeter thick neoprene,
and all of the neoprene used in the toe member 14 has a fabric,
such as nylon, covering both the inside and outside surfaces of the
neoprene. After the cuts are made in the right portion 76 and the
left portion 78, an adhesive that will form neoprene to neoprene
bonds, such as a contact cement like Weldwood.TM. brand contact
cement, is applied to the cuts so that the neoprene that was
separated by the cuts is rejoined. Similarly, the adhesive is used
to join the right portion 76 and the left portion 78 along the
intersection 80.
[0031] In the preferred embodiment, the front protective sole 60
comprises approximately two to three millimeter thick thermoplastic
rubber, such as Dynaflex.RTM. brand thermoplastic rubber. The front
protective sole 60 is attached to the outside of the toe member 14
using an adhesive such as Loctite.RTM. 401 brand ethyl
cyanoacrylate adhesive, and a primer, such as Loctite.RTM. 770
brand primer, as was described previously with respect to the rear
protective sole 62. After the adhesive have been applied to the
front protective sole 60, it is quickly pressed against the right
portion 76 and the left portion 78 simultaneously, thereby
attaching the front protective sole 60 to the toe member 14.
[0032] The front bottom member 32 is attached above the right
portion 76 and the left portion 78, using an adhesive such as 3M
Scotch-Grip Plastic Adhesive 1099.TM.. The specific thickness and
composition of the front bottom member 32 depends on the type and
size of the protrusions 20.
[0033] Earlier in the assembly process, usually after the cuts are
made in the neoprene to shape the toe member 14, the patch of hook
fasteners 36 is sewn onto the inside of the right flap 24, and the
patch of the loop fasteners 38 is sewn onto the outside of the left
flap 28. In FIG. 4, a stitch pattern 82 is visible on the inside
surface of the left flap 28 showing the outline of the patch of the
loop fasteners 38. Similarly, patches of the loop fasteners 40 and
42 are sewn onto inside surfaces of the straps 26 and 30,
respectively.
[0034] Referring to FIG. 1, it is obvious that there are several
ways that the protective covering can be assembled around the shoe
10. However, a representative way of putting on the covering is the
following: The right and left flaps 24 and 28 of the toe member 14
are opened up as is shown in FIG. 4. Then, while the shoe 10 is
being worn, the toe (front part) of the shoe 10 is inserted into
the toe member 14 with the spikes 20 being positioned over the
bottom member 32 and the toe of the shoe 10 being positioned
between the right flap 24 and the left flap 28. The left flap 28 is
then folded over the shoe 10, the right flap 24 is folded over the
left flap 28 and the two flaps 24 and 28 are fastened together by
pressing the hook fasteners 36 into the loop fasteners 38.
[0035] The heel member 18 is then positioned around the heel (back
part) of the shoe 10 with the sole of the shoe 10 resting on the
bottom member 48. The right strap 26 is pulled back towards the
heel member 18 and the loop fasteners 40 are attached to the hook
fasteners 50 on the right side of the cup portion 46. Then the left
strap 30 is pulled back towards the heel member 18 and the loop
fasteners 42 are attached to the hook fasteners 50 on the left side
of the cup portion 46. Finally, the ankle strap 54 is pulled over
the front of the ankle and the loop fasteners 56 are attached to
the hook fasteners 50. Again, the order of attachment is not
important and the shoe covering can be assembled in other
sequences. Oftentimes, once the protective covering has been
positioned over the shoe 10, it can be pulled off of the shoe 10
without unfastening the straps 26 and 30, and then can be
repositioned on the shoe 10 at a later time, without unfastening
the straps 26 and 30.
[0036] In alternative embodiments, the straps 26 and 30 are
modified to produce a toe member 14 that is positioned around the
shoe 10 in a slightly different manner. In a first alternative
embodiment, the straps 26 and 30 are lengthened so that they extend
around the heel section 23 of the shoe 10, and the loop fasteners
40 and 42 are replaced with fasteners that allow the strap 30 to be
attached to the strap 26. For example, the patch of loop fasteners
40 is replaced with a patch of hook fasteners, and the patch of
loop fasteners 42 are moved to the other side of the strap 30 so
that the loop fasteners occupy the region outlined by the stitch
pattern 63 shown in FIG. 2. After the toe member 14 has been
positioned around the toe section 22 of the shoe 10, the straps 26
and 30 are pulled around the heel section 23 and hooked together
using the hook and loop fasteners on the straps 26 and 30. This
embodiment eliminates the need for the heel member 18, and can be
used in situations where the protrusions 20 only extend from the
front part of the shoe 10. However, even in this situation, it is
preferable to still use the heel member 18, so that the front and
back of the shoe 10 are both approximately an equal distance off
the ground.
[0037] In a second alternative embodiment, the straps 26 and 30 are
permanently fastened together, such as by sewing or by making the
straps out of a continuous piece of material. The straps 26 and 30
are then pulled over the heel section 23 of the shoe 10 after the
toe member 14 is positioned, thereby eliminating the need for the
heel member 18.
[0038] There are many advantages inherent in the design of the
protective shoe covering of the present invention. First, the
flexibility of the neoprene used in the construction of the toe
member 14 means that a single size design of the toe member 14 can
fit many styles and sizes of the shoe 10. For example, it has been
found that just three sizes of the toe member 14 and three sizes of
the heel member 18 can be used to fit all of the American shoe
sizes from size three to size twelve or thirteen. This is possible,
in part, because the toe member 14 and the heel member 18 are
comprised of a flexible material. Hence, as used herein, the term
flexible material means a material that stretches to fit more than
one shoe size.
[0039] Similarly, the ability of the right flap 24 and the left
flap 28 to be pulled apart and opened up as shown in FIG. 4, allows
one size of the toe member 14 to be used with several sizes and
styles of shoe and makes it easy to position the toe member 14
around the shoe 10. This is especially important when the shoe 10
has sole protrusions, such as cleats or spikes. If the toe member
14 didn't open up, the protrusions would catch on the covering as
it was pulled over the shoe. This also allows a person to step into
the toe member 14 without having to stand on one leg while they
attempt to pull a covering over the shoe.
[0040] The fact that the heel member 18 is a separate piece from
the toe member 14 also allows a single size of heel member to be
used with several sizes and styles of the shoe 10. It is also easy
to position the heel member 18 over the shoe 10 and use the straps
26, 30 and 54 to achieve a tight fit of the toe and heel members 14
and 18 on the shoe 10.
[0041] The use of both the toe member 14 and the heel member 18
also makes it easier for the person wearing the protective covering
to walk. If for example, a protective covering only covers the toe
of the shoe 10, then a person wearing the shoe 10 is walking on an
uneven sole. However, if both the toe member 14 and the heel member
18 are used together, then a more even sole is achieved. The use of
the front protective sole 60 on the toe member 14 and the rear
protective sole 62 on the heel member 18 facilitates the comfort
and traction of the shoe covering.
[0042] There are many reasons for using the protective covering.
First, for shoes that have the protrusions 20, such as spikes,
cleats, taps, extending from the bottom of the shoe, the protective
covering protects the protrusions 20 from wearing out prematurely.
In this usage, the protective coverings are positioned around the
shoes 10 when the wearer is off the track or playing field and is
walking on a hard walking surface, like asphalt, concrete, wood or
tile. Generally, it is the front bottom member 32, and sometimes
the back bottom member 48, that protect the protrusions 20 from
premature wear. The thickness and composition of the front and back
bottom members 32 and 48 depends on the type and size of the
protrusions 20.
[0043] For example, for track and field shoes, regulating bodies
usually allow a maximum of six spikes per shoe, and these cannot
exceed a quarter inch in length when running on all-weather track.
Furthermore, all shoes worn by sprinters only have spikes in the
toe region, not in the heel region. For such shoes, a seven
millimeter thick neoprene front bottom member 32 provides the
primary protective cushion for the spikes to sink into, and is said
to help prevent at least some of the protrusions 20 from contacting
the walking surface. The front protective sole 60 provides a
durable sole that reduces the likelihood of slipping and also
provides some extra cushioning for the spikes. If there are spikes
on the heel of the shoe 10, then the back bottom member 48 will
provide cushioning for these spikes, and is said to help prevent at
least some of the protrusions 20 from contacting the walking
surface. However, even in cases where there are no heel spikes, the
back bottom member 48 and the rear protective sole 62 are
preferably used so that the heel and toe of the shoe 10 are resting
on surfaces approximately the same height off the ground. For other
types of protrusions 20, such as football or baseball cleats, or
golf spikes, the composition and thickness of the bottom members 32
and 48 can be varied.
[0044] Another reason for using the protective covering is to cover
dirty shoes, such as muddy soccer shoes. Use of the protective
covering keeps the mud mostly inside of the protective covering,
thereby protecting floors, carpets, car interiors or other areas
from getting soiled. Similarly, it is often desirable to protect
walking surfaces, such as floors, carpets, golf greens and other
surfaces from damage by the spikes. Use of the protective coverings
protects such surfaces.
[0045] Although the present invention has been described in terms

such disclosure is not to be interpreted as limiting. Various
alterations and modifications will no doubt become apparent to
those skilled in the art after having read the above disclosure.
Accordingly, it is intended that the appended claims be interpreted
as covering all alterations and modifications as fall within the
