Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims foreign priority of Korean Patent
Application No. 10-2011-0055194, filed on Jun. 8, 2011, which is
incorporated by reference in its entirety into this
application.
TECHNICAL FIELD
[0002] The invention relates to a shoe sole having superior
ventilation function and having a double-landing function being
able to have superior shock absorption function while walking and
to enhance ventilation property through smoothly flowing a fresh
air outside a shoe into an inside of the shoe.
BACKGROUND ART
[0003] Generally, person wears shoes to her or his feet and to
facilitate her of his movement. Various types of shoes are
manufactured to various types in order to satisfy various
functional aspects needed according to improvement of the standard
of living and widening activity area of person. For example, there
are various types of shoes such as running shoes, formal dress
shoes, work shoes, boots, hiking boots, and so on.
[0004] As such, shoes satisfy various functions according to
activity area of person, thereby providing improved convenience and
efficiency to the person in the active area. However, the shoes
have shapes just for surrounding and sealing feet. Thus,
temperature at surface portions of the feet surrounded by the shoes
are increased by friction between the feet and inner surface
portions of the shoes, and humidity is also increased by sweat
generated by the feet. Accordingly, an inside of the shoes and the
feet smell bad, and the feet get chronic diseases such as athlete's
foot.
DISCLOSURE
Technical Problem
[0005] The present invention has been made to solve the above
problems. More particularly, the present invention provides a shoe
sole having superior ventilation function and having a
double-landing function. The shoe sole is able to keep comfortable
and safe walking by absorbing shock during walk and to maintain a
pleasant environment by continuously supplying an air into an
inside of a shoe.
Technical Solution
[0006] A shoe sole according to an aspect to the invention has
ventilation function and has a double-landing function. The shoe
sole includes a main groove, and sole including a pressure pad of a
flat shape and connection portion. The main groove is formed on a
bottom surface at a heel area and communicates with a ventilation
groove supplying air into an inside of a shoe to supply the air
into the inside of the shoe. The pressure pad convexly protrudes
toward the ground at an area corresponding to the main groove. The
connection portion connects the pressure pad and the sole. The shoe
sole has a double-landing process. In the double-landing process, a
bottom surface of the pressure pad is in contact with the ground
and is introduced into the groove, and then, the bottom surface of
the sole is in contact with the ground. The connection portion is
thinner than the pressure pad so that the pressure pad is easily
introduced when landing.
Advantageous Effects
[0007] According to an embodiment of the invention, an air is
freely generated during walking and is supplied to an inside of a
shoe. A pressure pad protrudes toward the ground, and thus, an area
of an inner space between the pressure pad and a groove formed at a
mid-sole increases. Also, the force applied to the mid-sole from a
body during walking and the force applied to the pressure pad from
the ground are simultaneously generated, and thus, an inner
pressure increases. As a result, an air-generation amount improves
and a shock-absorption force increase, thereby enabling pleasant
and comfortable walking.
[0008] Also, a slip during walking can be prevented by a
double-landing through a mutual operation of the pressure pad and
the bottom surface of the sole. Accordingly, safe walking can be
possible.
[0009] Further, in the embodiment of the invention, the pressure
pad and the groove are formed at an entire area of elbow and a
heel, and communicated to each other through a flow path pipe.
Therefore, the air-generation amount and the shock-absorption force
can increase more.
[0010] By the above functions, pain of joints, such as a heel, an
ankle, a pelvis, and a spine, can be relived. The pressure of the
foot can be distributed. Also, bacterial affections such as
athlete's foot and eczema can be prevented by generating and
ventilating air. Thus, the shoe sole can be applied to various
shoes as well as shoes for foot-disease patient (for example, a
patient having foot disease due to diabetes).

manner that the invention may easily be carried out by a person
having ordinary skill in the art to which the invention pertains.
In the descriptions regarding an operation principal of the

components that may vague technical feature of the invention will
be omitted.
[0019] Hereinafter, with reference to FIG. 1 to FIG. 7, embodiments
of the invention will be described in detail.
[0020] FIG. 1 is an exploded perspective view of a shoe sole
according to the invention. FIG. 2 is a plan view of a mid-sole
according to the invention, FIG. 3 is a top perspective view of the
mid-sole according to the invention, and FIG. 4 is a

shoe sole according to the invention, and FIG. 7 is a view for
illustrating contraction of the shoe sole according to the
invention.
[0021] As shown in FIGS. 1 to 3, a shoe sole according to the
invention includes a mid-sole 100 and a sole 200. The mid-sole 100
includes a main groove 110 formed on a bottom surface of an area
where a heel is in contact, and a ventilation groove 120 formed on
an upper surface of an area where elbow is in contact. The sole 200
includes a pressure pad 210 formed at an area corresponding to the
main groove 110. The shoe sole is manufactured by assembling the
mid-sole 100 and the sole 200.
[0022] The mid-sole 100 may be formed of a soft material having
elasticity to have shock-absorption function. The main groove 110
formed at the mid-sole 100 is formed to have predetermined or
regular depth. Thus, the main groove 110 generates air by a
pressure due to the pressure pad 210. The ventilation groove 120 is
formed at the upper surface of the area of the mid-sole 100 where
the elbow is in contact. The ventilation groove 120 communicates
with the main groove 110. The air generated at the main groove 110
is flows into the ventilation groove 120, and then, is supplied to
an inside of the shoe.
[0023] Hereinafter, it is described that the main groove 110
communicates with the ventilation groove 120 in detail. The main
groove 110 communicates with the ventilation groove 120 through a
flow path pipe 130 coupled to the mid-sole 100. As shown in FIGS. 2
and 3, one end of the flow path pipe 130 is connected to the main
groove 110, and the other end of the flow path pipe 130 is
connected to the ventilation groove 120, thereby communicating the
main groove 110 and the ventilation groove 120. In this state, as
shown in FIG. 4, the flow path pipe 130 is connected to the main
groove 110 at one end of the flow path pipe 130, is extended in a
longitudinal direction of the bottom surface of the mid-sole 100,
penetrates through and protrudes to the upper surface of the
mid-sole 100 at a central area of the mid-sole 100, and then, is
extended along a longitudinal direction of the upper surface of the
mid-sole 100 to the ventilation groove 120. Therefore, the air
generated at the main groove 110 flows through the flow path pipe
130 and flows into the ventilation groove 120.
[0024] The pressure pad 210 formed at the sole 200 has a flat shape
or a planar shape. The pressure pad 210 may be formed of a rubber
material having elasticity. The pressure pad 210 is convex to
protrude from the bottom surface of the sole 200 to the ground.
When landing, the entire bottom surface of the pressure pad 210 is
in contact with the ground and is introduced toward the main groove
110, thereby generating air and absorbing shock. That is, when
landing, the pressure pad 210 convexly protruding toward the ground
is in contact with the ground and is introduced toward the main
groove 110, thereby increasing inner pressure of the main groove
110 and generating air. The generated air flows through the flow
path pipe 130 and flows into the ventilation groove 120.
[0025] In this instance, at the sole 200, a connection portion 214
connecting the pressure pad 210 and the sole 200 along an edge
portion is formed along the edge portion of the pressure pad 210.
The connection portion 214 is thinner than the pressure pad 210,
and is convex toward the main groove 110. That is, this is for
smoothly introducing the pressure pad 210. The edge portion of the
pressure pad 210 connected to the sole 200 convexly protrudes, and
thus, it is extended. Thereby, the lengthened edge portion can be
compensated by tensile force generated at the edge portion while
the pressure pad 210 is introduced. As a result, the pressure pad
210 can be smoothly introduced.
[0026] On the other hand, a mid-sole protrusion 112 having a
cylindrical shape is formed in the main groove 110. The mid-sole
protrusion 112 protrudes from the bottom surface and has an end
being in contacted with the pressure pad 210. The mid-sole
protrusion 112 is contracted and expanded to be in contact with the
pressure pad 210 in order to support the pressure pad 210 and to
absorb shock. That is, when landing during walk, the pressure pad
210 is introduced into the main groove 110, and the mid-sole
protrusion 112 is contracted and absorbs shock generated at the
pressure pad 210. When the pressure pad 210 protrudes to an outside
again, the mid-sole protrusion 112 is expanded and continuously
supports the pressure pad 210. In this instance, the shape of the
mid-sole protrusion 112 is not limited to the cylindrical shape.
Thus, the mid-sole protrusion 112 has various sizes and various
shapes to have optimal shock-absorption amount according to sizes
and shapes of shoes.
[0027] Also, a pad groove 212 where the mid-sole protrusion 112 is
inserted is formed on the upper surface of the pressure pad 210.
The pad groove 212 is formed at an area corresponding to the
mid-sole protrusion 112 being inserted into the pad groove 212 and
surrounds an outer surface of the mid-sole protrusion 112.
Accordingly, while the pressure pad 210 is introduced into the main
groove 110 and the mid-sole protrusion 112 is contracted or while
the pressure pad 210 protrudes toward the ground and the mid-sole
protrusion 112 is expanded, the pad groove 212 surrounds the outer
surface of the mid-sole protrusion 112. Thus, the pad groove 212
prevents the mid-sole protrusion 112 being distorted or separated
from the pad groove 212 and enhances shock-absorption force.
[0028] In addition, as shown in FIG. 5, an auxiliary pad (or
auxiliary pads) 220 is further formed at an area of the sole 200
corresponding to an auxiliary groove 140. Thus, the operation same
as that between the auxiliary pad 220 and the auxiliary groove 140
is generated between the pressure pad 210 and the main groove 110.
Accordingly, the shock-absorption amount and the air-generation
amount can be increased more.
[0029] A process of absorbing the shock and generating and flowing
the air by the shoe sole having the above structure during walking
will be described with reference to FIGS. 6 and 7.
[0030] When landing, as shown in FIG. 6, the entire bottom surface
of the pressure pad 210 simultaneously is in contact with the
ground and the pressure pad 210 is introduced into the main groove
110. Thus, the inner air of the main groove 110 flows through the
flow path pipe 130, reaches the ventilation groove 120, and flows
into the inside of the shoe. Also, while the pressure pad 210 is
introduced, the mid-sole protrusion 112 supporting the pressure pad
210 is gradually contracted. That is, a first landing process for
sufficiently absorbing the shock is performed.
[0031] And then, the pressure pad 210 is totally inserted into the
main groove 110, and the bottom surface of the pressure pad 210 and
the bottom surface of the sole 200 are aligned with or flushed with
each other. A second landing process that the entire bottom surface
of the sole 200 is in contact with the ground is performed. Thus, a
complete and stable landing can be possible. The air-generation
amount and the shock-absorption amount are increased by a
double-landing process through the introduction of the pressure pad
210. Accordingly, a pleasant environment can be maintained and
comfortable walking can be possible.
