(a) Technical Field of the Invention
[0001] The present invention generally relates to a foot balance device that adjusts force
distribution on human foot and is particularly applicable to leather shoes, sports
shoes, loafers, high-heal shoes, and the likes.
(b) Description of the Prior Art
[0002] The economic development and progress makes the opportunity of taking physical activity
remarkably reduced in the modem living and the consequence is insufficiency of physiological
loading for modem people. This leads to the emergence of disease of civilization,
including metabolic syndrome, obesity, hypertension, hyperlipidemia, and deterioration
of cardiopulmonary function.
[0003] In addition to the diseases of civilization, chronic pains are also very common in
the modem society The general causes for the chronic pains are basically improper
motions and gestures that make bones and muscles losing balance. In view of creature
evolution, in the evolution course of human beings, humans changed from an animal
walking with four legs to an animal walking with two legs. To maintain balance for
standing with two legs and walking in an upright posture with the two legs, bones
and muscles are forced to coordinate with each other to induce an effect of compensation,
so that the human body does not get falling in an upright posture in standing with
two legs and also can move forward in the upright, two leg standing posture.
[0004] Such a compensation effect is an interaction induced between bones and muscles and
such an interaction between bones and muscles may easily lead to improper motions
and gestures when humans are standing and walking. Such improper motions and gestures
may make bones and muscles losing balance and as a consequence, the chronic pans discussed
above, as well as other sours and pains, may occur.
[0005] The chronic pains and other sours and pains are generally brought by the general
effect of compensation of human body and techniques of the related medical field or
science may not be possible to solve these problems. In other words, the current medical
or scientific techniques and knowledge cannot provide a simple and effective solution
to constantly maintain the bones and muscles of human body in a balanced condition
in the every living and is also incapable of avoidance of sours and chronic pains
that were mentioned above caused by improper motion and gestures.
[0006] When a human body is standing or walking, the perfect condition is that the force
that the heel and the sole take is uniformly distributed and the support to the total
body weight is substantially at a center of the sole, as shown in FIG 1, whereby the
bone and muscle systems may be kept at a neutral and balanced position when a person
is standing or walking. However, under a natural condition, the sole is subjected
to influence of the design of shoes. When the heel unduly applies a force, the heal
may be hurt and the shoe heal get damaged. On the other hand, when an undue force
is applied by the sole, a rush may occur in walking forward, or as shown in FIG 2,
pigeon toeing may occur in walking, where the body weight is not uniformly distributed,
making one of heel, sole, or heel and either an inside portion or an outside portion
of sole bearing a great pressure. This is adverse to body balance and may change the
way of standing or walking to cause improper motion and gesture.
[0007] To resolve the above discussed problems, a conventional solution that a podiatrist
or a shoe manufacturer may take is to add a post in the shoe, or place an elastic
material in a cavity formed in the shoe heel, or adopt a design of heel cup. However,
such solutions may sometimes cause an increase of force applied to the heel or sole,
making it impossible to resolve the problems. This is because that those know solutions
including post, elastic material, and heel cup, although changing the improper gesture
caused by non-uniform distribution of force on the heel and sole, cannot be effectively
decrease the pressure acting on the heel and sole.
[0008] In view of these problems, the present invention aims to overcome the drawbacks of
the conventional solution for adjusting pressure acting on foot by providing a foot
balance device of which a detailed description of a preferred embodiment will be given
as follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] The following descriptions are exemplary embodiments only, and are not intended to
limit the scope, applicability or configuration of the invention in any way. Rather,
the following description provides a convenient illustration for implementing exemplary
embodiments of the invention. Various changes to the described embodiments may be
made in the function and arrangement of the elements described without departing from
the scope of the invention as set forth in the appended claims.
[0024] As shown in FIG 3, the present invention comprises at least one adjustment element
10, and the adjustment element 10 forms a support point. The adjustment element 10
has a bottom surface that is provided with a coupling section 11 for coupling purposes.
The support point is of a shape of any of a circle, an ellipse, and a rectangle. Further,
the support point has a top surface that is any one of a raised surface, a circular-curved
surface, a semi-circular-curved surface, and an irregular surface. The coupling section
11 can be any one of adhesive, double-sided adhesive tape, and hook-and-loop fastener.
In the instant embodiment, an example having a circular shape, a raised surface, and
double-sided adhesive tape is described for illustration purposes. To use, the adjustment
element 10 is placed in a shoe at a location corresponding to a middle portion of
a foot between inside arch and outside arch between the front sole and the rear heel.
A user may take trials of putting on the shoe to adjust the final position of the
adjustment element 10. After the position adjustment, the adjustment element 10 can
be fixed in position inside the shoe by the double-sided adhesive tape.
[0025] As shown in FIGS. 4, 5, and 9, a second example of use of the embodiment according
to the present invention is illustrated, which comprises a shoe pad 20 and at least
one adjustment element 10. The shoe pad 20 is divided into and composed of a sole
section, a heel section, and an arch section 21. The adjustment element 10 forms a
support point. The adjustment element 10 has a bottom surface that is provided with
a coupling section 11, which is in the example, a piece of double-sided adhesive tape,
for coupling purposes. Also referring to FIGS. 6 and 7, the adjustment element 10
is arranged on four circumferential portions of front side, rear side, left side,
and right side of the arch section 21 of the surface of the shoe pad 20 according
to the preference and convenience of a user, whereby adjustment element 10, when used
by a user, serves as a fulcrum of leverage, allowing of frontward, rearward, leftward,
and/or rightward movement according to the height of shoe heel to induce a seesaw
effect between the foot heel and sole and thereby uniformly distributing pressure
on the foot, as shown in FIG 8. Further, referring to FIG 11, the adjustment element
10 can also be coupled by the coupling section 11 to a proper frontward, rearward,
leftward, or rightward location on the back surface of the arch section 21 of the
shoe pad 20 to achieve the same effect.
[0026] As shown in the drawings, an embodiment of the present invention may comprise a shoe
pad and at least one adjustment element. The shoe pad is divided into and composed
of a sole section, a heel section, and an arch section. The adjustment element serves
as a support point for the front sole section in order to make balance of the sole
between left and right sides. The adjustment element serves as a balance support point
of the sole section and the heel section. The adjustment element serves as a horizontal
support point of the foot. The adjustment element serves as a support point of the
inside arch. The adjustment element serves as a support point of the outside arch.
The adjustment element is the preferred embodiment of shoe pad. The show pad is divided
into a sole section, a fulcrum of leverage, and a heel section. By using the adjustment
element to form a foot sole seesaw effect, the pressure can be uniformly distributed
on the foot sole. When a user is standing or walking, the gravity center of the body
does not shift frontward or rearward, so that the user may naturally take a chin-up
and chest-out posture thereby achieving the best result of the present invention.
[0027] Further, as shown in FIG 10, the adjustment element 10 can also be coupled inside
a shoe 30 by the coupling section 11 at a location corresponding to the foot arch
(by first lifting up the shoe pad 20 received in the shoe 30). The shoe pad 20 is
then put back into the shoe 30 to cover the adjustment element 10.
[0028] It will be understood that each of the elements described above, or two or more together
may also find a useful application in other types of methods differing from the type
described above.
