FIELD OF THE INVENTION
[0002] The present invention relates to shoes generally and, more
particularly, to a transformable shoe having a sole that allows
different height heels to be detached and/or attached easily.
BACKGROUND OF THE INVENTION
[0003] Shoes as conventionally manufactured cannot transform into
shoes with varying heel heights or no heel at all. The reason for
this problem is the current manufacturing process. Currently high
heels are permanently attached to the sole of the shoe. The heels
cannot be removed unless they are broken away from the sole. A shoe
with a broken high heel is unwearable for any walking distance.
[0004] Conversely shoes without heels or flat style shoes cannot be
transformed into high heel or any other heel height. Currently the
manufacturing process does not allow for shoes to be transformed
into any style shoe other then what they are. The walking motion of
high heel shoes is different than the walking motion of flat style
shoes. The walking motion of high heel shoes involves putting more
weight on the ball of the foot and toes. The toe portion of the
shoe comes in contact with the floor surface at the same time as
the heel. The downward pressure of the person's weight is thrust
down on the ball and toes of the foot.
[0005] High heel shoes can only be worn for a limited time due to
this said downward pressure on the ball and toes of the foot. A
person can only wear high heel shoes for only so many hours. After
a time, discomfort sets in. The downward pressure on the ball and
toes of the foot cause this discomfort. The person either has to
stop walking or take off the high heel shoes. After the person
cannot wear the high heel shoes, they have either the choice of
changing shoes or removing them and going barefoot.
[0006] Also, it is difficult for a person to wear high heel shoes
on a bus, or a train, walking across a parking lot, getting in and
out of a car, up and down staircases, on a slippery floor, outdoors
in the rain or snow, etc. The surface area that comes in contact
with the floor or ground of a high heel shoe is very small. The
high heel surface area combined with the toe area of the shoe is
very small as compared with that of a flat style shoe. Also when
walking the downward pressure of the weight on the high heel can be
very unstable on a slippery, wet, icy, uneven, or hilly surface.
Wearing high heels on any of these surfaces can be very difficult
or even dangerous.
[0007] A high heel is used by people for certain occasions, and a
flat style shoe is used for other occasions. When a person goes out
to a formal affair, they will need to wear high heel shoes. Formal
affairs include weddings, concerts, dates, etc. The formal
occasions usually include dancing. Women love to dance in high
heels. Then, later that night their feet hurt and they cannot
continue to wear the high heel shoes. The high heel shoes are taken
off because of the discomfort. At the end of a night of dancing you
see a lot of women walking around barefoot. The problem being a
person has to carry two sets of shoes or walk around barefoot
carrying the shoes.
[0008] Flat style shoes are worn on other occasions. These other
occasions usually involve a lot of walking or time spent on ones
feet. These other occasions can include work, school, shopping,
strolling, etc. The walking motion in a flat style shoe involves
making an initial contact of the walking surface with the heel. The
heel hits the floor or ground first. The weight is then transferred
to the toe portion of the shoe as each step is taken. This is a
more natural motion of walking than that of a high heel shoe.
[0009] Arch support is required in the normal walking motion within
the shoe. This occurs in a normal foot between the ball of the foot
and the end of the heel area. There is an arch in a foot that must
be supported. In conventional shoe design there is a raised arch in
the sole of the shoe to support this natural arch in the foot. A
high heel must absorb the downward weight of the person. When
standing or walking in high heels the person's weight is
concentrated on the central part of the heel and the ball of the
foot.
[0010] High heel shoes can be worn for only a limited amount of
time, but are required at certain occasions. Flat style shoes can
be worn for a much longer period of time and are worn for other
occasions. The problem with conventional shoes is that a person
needs two pairs of shoes and this is not always the case. An
example of this situation is a person is at work wearing their flat
style shoes and receives an invitation to go to a formal affair
that requires high heel shoes. The person needs to go home or
shopping to obtain a pair of high heel shoes.
[0011] It would be desirable to have a transformable shoe having a
sole that allows different height heels to be detached and/or
attached easily.
SUMMARY OF THE INVENTION
[0012] The present invention concerns a shoe assembly including a
front sole section, a rear sole section, a heel, and a hinge. The
front sole section has a front sole section rear edge. The rear
sole section includes a rear sole section front edge, a shank, and
a release button. The heel may be removably attached to the shank
and may be released from a locked position by the release button.
The hinge connects the front sole section and the rear sole
section. The hinge is perpendicular to a rear sole section
axis.
[0013] The objects, features and advantages of the present
invention include providing a transformable shoe having a sole that
allows different height heels to be detached or attached easily
that may (i) include a shank configured to interlock with a heel
being attached, (ii) form a truss with a support rod securing a
heel that has been attached, (iii) change angle to orient to
different height heels, (iv) provide a quick release mechanism that
facilitates heel changes, (v) be implemented as a customizable shoe
kit, and/or (vi) provide a wearer with a shoe that can change heel
height.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0066] The present invention was developed as a result of research
into the problem associated with making shoes with heels that can
be detached and/or replaced with heels of different heights.
Embodiments of the present invention can also function as a flat
style shoe when no heel is attached to the sole. The present
invention provides a transformable shoe that provides the wearer
with a combination of shoe styles. In one example, the present
invention may be embodied in a customizable shoe kit that provides
interchangeable heels with two or more heel heights. The shoe can
transform from a high heel shoe to a flat style shoe or somewhere
in between. This is accomplished by providing a sole that can
change angles to accommodate for different height heels. The sole
comprises a front toe section and a rear sole section. The two
sections can be connected with a hinge. The hinge allows the rear
sole section to rotate to accommodate for different height
heels.
[0067] The design of the sole of the invention solves the problem
of discomfort present in current high heel shoes. In conventional
high heel shoes, the sole from front to rear is a rigid frame.
Embodiments of the present invention provide a hinge in the sole
that provides some flexibility. The flexibility in the sole can
reduce discomfort by balancing forces from the toes to counteract
instability in the heel area and reduce the wobbling situation that
exists in a rigid sole.
[0068] In the current method of construction of a high heel shoe
the central part of the heel contains a post. The post is attached
to a steel shank embedded in the sole of the shoe. The shank can be
made of a flexible metal or other strong material. The shank can be
flexible enough to assume the flat position of the sole and still
be strong enough to provide the necessary strength within the sole
to absorb the downward force from the weight of a person. The heel
post generally comprises a rigid material and rigidly couples to
the shank through a mortise and tenon like connection. In various
embodiments, the heel post includes a notch configured to lock the
heel post into the shank. The heel post may formed (e.g., through
casting, machining, forging, etc.) using various metals, plastics,
or other appropriate material that provides strength and rigidity.
In various embodiments, a portion of the heel post slides into a
slot in the shank and is locked in position by a release mechanism.
The heel post extends down from the sole to the bottom of the heel.
The heel is centered around this post. The post is usually a metal
material. However, other equivalent materials may used accordingly
to meet the design criteria of a particular implementation.
[0069] Also, there is a geometric distance from the ball of the
foot to the heel. This geometric distance remains constant whether
the shoe is in the flat style position or it is in the high heel
position. The sole rotates and changes angle from the flat
configuration to the high heel configuration and the distance from
the ball of the foot to the heel does not change.
[0070] A significant comfort advantage over the conventional high
heel shoes is the stability provided by the hinged connection
between the front sole and the rear sole. This allows balancing
forces from the front toe section to be applied to aid in
controlling instability within the shoe when the high heel is
attached. In one example, the hinged connection can be formed using
a live hinge. For example, a flexible material may be used to
connect the front sole and the rear sole.
[0071] The walking motion while wearing high heels is different
than flat style shoes. The normal walking motion of wearing flat
style shoes consists of the heel comes in contact with the floor or
ground first. Than the persons weight is transferred to the arch of
the foot and then finally the toes. The walking motion while
wearing high heel shoes is different. The high heel comes in
contact with the floor or ground and the same time as the toe
section.
[0072] Embodiments of the present invention generally provide for
replaceable heels of different heights or styles. The person can
easily detach the high heel (e.g., by pushing or pulling a release
button) and replace the high heel with a mid height heel or low
height heel, and vice versa. The person can also detach the heel
and transform the shoe into a flat style shoe. The heels can be
stored easily, (e.g., in the person's purse). Wearing a flat style
shoe provides the wearer with more comfort and the walking motion
is more natural. The person can easily transform the flat style
shoes by attaching the high heel back onto the sole of the
shoe.
[0073] Embodiments of the present invention may also provide for a
fashion statement. The ability to replace heels can easily change
the wardrobe. An example of this is replacing a black color high
heel with a red color high heel to match the person's red purse.
Replacement heels can also be different shapes or styles. An
example of this is a cocktail waitress can replace her high heel
with a high heel that is a "martini" glass.
[0074] The height of the high heel can be of any height. The hinge
can rotate to any angle to accommodate for the desired heel height.
If an extremely high heel height is required, the rotation of the
hinge might not be enough to accommodate for this. In this case a
platform of a desired height can be added to the front toe section
of the sole to accommodate for a higher heel height.
[0075] The shoe frames and heels in accordance with embodiments of
the present invention can be transformed from a walking shoe,
having a low heel height, to a shoe having a higher heel height,
conveniently and rapidly. A high heel that is detachable and
replaceable. In addition, the shape of the shoe frame can be
changed to increase the comfort of the wearer depending on the
height of the heel chosen.
[0076] The shoe frame as described below is independent of the
final appearance of the shoe which can vary according to the
dictates of the shoe designer. The high strength shoe elements
described herein are meant to be covered with standard liners,
cushion materials, uppers, sole coverings and heel coverings, which
can be made of various materials known to those skilled in the art
such as leather, various man made materials and resins, fabric and
the like. The transformable heel can be made of metal or other high
strength material, which may be covered with leather, plastic,
fabric and the like, or can be made of other materials. The basic
structure of the shoe frame in accordance with embodiments of the
present invention is independent of the size, shape, type and
materials which provide the final appearance of the shoe.
[0077] The present invention generally provides for a sole with two
sections connected with a hinge that can rotate and change angles
to accommodate different heel heights. The hinge described in the
following drawings is a preferred method. The hinge can be
accomplished by other methods other than the ones described below.
The hinge can be a separate piece and attached to the sole. The
sole can also be implemented with a live hinge (e.g., one
continuous piece of flexible material capable of change
angles).
[0078] Heels of varying heights may be attached and detached to a
shank in the sole of the shoe. The drawings are illustrative of a
preferred embodiment of attachment and detachment of the heel to
the sole. However, other methods of attachment, such as sliding
into grooves, clipping, or snapping are envisioned.
[0079] The toe portion of the sole and the heel portion of the
transformable shoe sole of the invention can be constructed in a
variety of methods. Generally each portion of the sole can be
constructed in one piece or layers of materials plied together. It
can be made of an injection molded polymer or other synthetic
material. The two piece sole may have a hinge type joint in the
metatarsal region. This is the approximate location of where the
ball of the foot of a person will be engaging. The hinge joint may
have a built-in defined range of motion or may have an infinite
amount of rotation. Contacting surfaces of the hinge may be
texturized, for example, to cause some limited restriction to
flexion and extension, and also to act as a shock absorber. Other
ways of adjusting the angle of the individual portions of the shoe
sole will suggest themselves to one skilled in the art, and are
meant to be included herein.
[0080] It will be apparent that the shoe designer has a wide choice
among the various embodiments shown here in both the shoe sole
elements and the heel elements, depending on the ultimate design of
the shoe, and the relative heights of the high heel and the low
heel versions. The shoe frame and heel as described above are not
meant to be limited to the details described herein, but many
variations thereof will be apparent to one skilled in the art. For
example, the shoe frame can be made of additional portions so as to
allow for greater variation of the contour of the sole and the
relative positions of the arch with respect to the heel and toe
portions of the shoe, thereby providing for a wide variation in
design.
[0081] The detachable heel can, as an option, contain a sturdy pin
in its interior to provide for structural support when weight is
applied by the person stepping down on the sole of the shoe. The
relative positions of the sole portions can be adjusted to allow
for variations in the height and shape of the extended heel to be
employed. Embodiments of a shoe frame and heel in accordance with
the present invention may include, but are not limited to, the

[0166] In the embodiments illustrated in FIGS. 43 through 51, the
button rod, shank, and heel post configuration enable the heels to
be switched (exchanged) without removing the shoe. Thus, the
embodiments illustrated in FIGS. 43 through 51 may also be applied
to shoes and boots which include lacings.
[0167] The term dress shoes include a wide variety of shoes, e.g.,
opera pumps to high fashion shoes. Dress shoes can have a wide
range of heel heights and shapes, from a modest 2 inch heel to a 4
or 5 inch stiletto heel. The higher the heel, the more difficult
the shoes are to walk in for extended periods and distances than
flat heeled shoes, and they slow down the walker. Thus it has
become the norm for people to wear low heeled walking shoes to and
from work, and then to change shoes when they reach their place of
business or the club for dancing. This necessitates someone
carrying high heel shoes along with a pair of flat walking shoes
back and forth, or maintaining an extensive shoe wardrobe at the
workplace.
[0168] In one example, a shoe may be built with a two piece sole
capable of changing angles to allow for the attachment of different
size heels could be produced. The shoe may serve as a flat style
shoe with a low heel, along with heels of various heights. Such a
shoe may be worn comfortably as a flat style shoe and then easily
transformed into a high heel or other height heel shoes.
Conversely, a high heel shoe may easily be transformed back into a
mid-height heel, or a flat style shoe again.
[0169] The high heels or mid range heels that have been detached
may be stored in the persons purse or other storage device. Other
advantages of the replacement heel may include, but are not limited
to:
[0170] 1. The heel can also be replaced with a different heel of a
different style or color. In the field of footwear, a need has been
recognized for a more economical way to match the footwear to the
person's wardrobe than having one or more pairs of shoes for each
suit, dress, or casual outfit that a person may own. For example,
red heels to match a red purse.
[0171] 2. Replacement heels can be used to replace broken heels.
High heels are sometimes easily broken when stepping off a curb or
something similar. Replacing a heel is more economical than
replacing a pair of shoes.
[0172] 3. Replacement heels of various height heels. If a person is
at an occasion that requires a midrange heel, it can easily be
replaced with just that.
[0173] 4. The heel can be replaced with a custom shape heel. Heels
can be of different designs and shapes and can be easily attached
to the shoe. An example of this would be a cocktail waitress can be
wearing a set of heels that look like a "martini glass".
[0174] While the invention has been particularly shown and
described with reference to the preferred embodiments thereof, it
will be understood by those skilled in the art that various changes
in form and details may be made without departing from the scope of
the invention.
