Description
FIELD OF THE INVENTION
[0001] The present invention relates, in general, to shoes and,
more particularly, to shoes having an improved cushioning structure
to relieve shocks applied to the sole of a user's foot.
BACKGROUND ART
[0002] Generally, shocks are applied to a user's foot while he or
she is walking or exercising with wearing shoes. If shock power is
continuously applied to the foot, the user wearing the shoes may
suffer from uncomfortableness, fatigue or injury.
[0003] To absorb this shock power, shoes are usually provided with
cushions for absorbing the shocks. The shock absorbing cushion is
mounted on the mid-sole portion in the rear of the shoe.
[0004] In the case of a shock absorbing cushion made of synthetic
resin, it is worn as it has been used for a long period of time,
and the original shock absorbing capacity is lost due to the load
continuously applied.
[0005] In addition, in the case of a shock absorbing cushion
employing an airbag, the air filled in the airbag is leaked due to
friction, or collision or abrasion with any sharp material, thereby
posing a danger of losing the shock absorbing function.
[0006] According to this, the conventional shoes are incapable of
continuously absorbing the shock power generated in the course of
walking, whereby shocks caused when the user takes a step are
directly transferred to the foot and also the user would have
disagreeable feeling of wearing the shoes.
DISCLOSURE OF INVENTION
[0007] Accordingly, the present general inventive concept provides
shoes capable of improving the feeling of wearing them by
effectively relieving the shock power transferred to a user's foot,
and enhancing the user's health by discharging air closed within
the shoes to the outside through air circulation and removing heat,
sweat and stench generated inside the shoes.
[0008] Additional aspects and advantages of the present general
inventive concept will be set forth in part in the description

through which partial air of the receiving part is discharged
toward the outside of the outsole; and an air check valve provided
in the air discharging passage, to prevent air discharged to the
outside through the air discharging passage from flowing
backward.
[0010] The air check valve may comprise a receiving part cap
detachably coupled with the air discharging passage, being formed
with an inlet through which the partial air of the receiving part
flows into the air discharging passage; an external cap detachably
coupled with the air discharging passage with a predetermined
spacing from the receiving part cap, being formed with an air
exhaust hole through which the air within the air discharging
passage is exhausted to the outside of the outsole; an
opening/closing rod provided between the receiving part cap and the
external cap, to open and close the inlet hole by contacting and
being separated from the receiving part cap; and a valve spring, to
provide a predetermined degree of elasticity, so that the
opening/closing rod closely contact the receiving part cap.
[0011] The cushion support part may comprise a plurality of
springs; a lower cap having a plurality of spring supporters to
respectively support one end of the spring, being received in the
receiving part; a upper cap elevatably provided in the spring
supporters, being formed with a plurality of elevating rods to

MODES FOR CARRYING OUT THE INVENTION
[0025] Reference will now be made in detail to the embodiments of
the present general inventive concept, examples of which are
illustrated in the accompanying drawings, wherein like reference
numerals refer to like elements throughout.
[0026] FIG. 1 is an exploded perspective view of an exemplary
embodiment of the present invention, and FIG. 2 is a side section
view of FIG. 1. Referring to these figures, a shoe 1 according to
an exemplary embodiment of the present invention comprises an
outsole 11 forming the bottom of the shoe 1, a mid-sole 13 provided
on the top of the outsole 11, an insole 15 provided on the top of
the mid-sole 13, contacting the sole of a user's foot, and a upper
sole 17 provided along the upper circumference of the mid-sole,
forming a space for receiving the user's foot.
[0027] In toe and heel portions of the mid-sole 13 are provided
receiving parts 21a and 21b to receive cushion support parts 31a
and 31b to be described later. The receiving parts 21a and 21b are
depressed to a predetermined depth from the top face of the
mid-sole 13. Between the receiving parts 21 and 21b are formed a
plurality of grooves 23 each having the shape of a hemisphere in
section, mutually communicating the receiving parts 21a and 21b.
Air within the receiving parts 21a and 21b flows along the grooves
23.
[0028] An auxiliary receiving part 25 to receive a perfume and/or
an anti-bacteria agent therein is provided between the receiving
parts 21a and 21b of the mid-sole. The auxiliary receiving part 25
is shaped with a square in section, being depressed to a
predetermined depth from the top face of the mid-sole 23 so as to
be able to communicate with the plurality of grooves 23. According
to this, the perfume and anti-bacteria agent received in the
auxiliary receiving part 25 are discharged into the inside of the
shoe 1 through a first air passing holes 15a formed in the insole
15 by way of each of the receiving parts 21a and 21b along the
grooves 23, thereby removing stench and bacteria generated inside
the shoe 1 and enhancing the user's health.
[0029] In the receiving parts 21a and 21b of the mid-sole 13 are
provided the cushion support parts 31a and 31b respectively so as
to relieve shocks applied to the user's foot.
[0030] As illustrated in FIGS. 3 and 4, the cushion support parts
31a and 31b each comprise a plurality of springs 33, a lower cap 35
to support one end of the spring 33, being received in each of the
receiving parts 21a and 21b, a upper cap 51 elevatably to support
the other end of the spring 33, being coupled with the lower cap
35, and a screw 57 interconnecting the lower cap 35 and the upper
cap 51.
[0031] The springs 33 stand between the lower cap 35 and the upper
cap 51 with a predetermined interval, providing a predetermined
degree of elasticity so as to allow the lower cap 35 and the upper
cap 51 to be maintained with the predetermined interval. Here, the
spring 33 is preferably made of a cone-shaped coil spring. It is
more effective that a cone part of the spring 33 is directed toward
the bottom of the upper cap 51.
[0032] The lower cap 35 has a plate-shaped main body 37, and a
plurality of spring supporters 43 coupled with the main body 37 so
as to support one end of the spring 33.
[0033] On the plane of the main body 37 directed toward the bottoms
of the receiving parts 21a and 21b are formed passing holes 39
through which the spring supporters 43 pass. On the circumference
of each passing hole 39 is formed an engaging groove 41 with which
an engaging part 45 of the spring supporter 43 is engaged.
[0034] The spring supporter 43 is substantially shaped with an
inverse "U" in section, and it is mounted on the main body 37 in
such a manner as to be projectable toward the upper cap 51. On the
outer circumference of the spring supporter 43 is mounted an end of
the spring 33, and an engaging part 45 engaged into the engaging
groove 41 of the upper cap is formed on the circumference of an
opening of the lower region of the spring supporter 43. In
addition, on the top region of the spring supporter 43 is formed a
passing hole 47 through which an elevating rod 53 to be described
later, and an engaging projection 49 with which a head 57b of the
screw 57 to be described later is engaged is formed on the
circumference of the passing hole 47.
[0035] The upper cap 51 is shaped with a cylinder, one side of
which is opened. On the plane of the upper cap 51 are projected a
plurality of elevating rods 53 to support the other end of the
spring 33, which are directed toward the lower cap 35. Each of the
elevation rods 43 is shaped with a rod, in the central region of
which a female screw 53a with which a screw shaft 57a of the screw
57 is screw-coupled is formed. A free end of the elevation rod 53
is coupled with the lower cap 35 by passing through the passing
hole 39, and elevatably coupled with the spring supporter 43.
[0036] In addition, on the plane of the upper cap 51 is formed a
plurality of second air passing holes 51a by passing through it, to
communicate with the receiving parts 21a and 21b. It is preferred
that the second air passing holes 51a of the upper cap 51 are
formed in such a manner that they are communicable with the first
air passing holes 15a formed on the insole 14, to thereby
communicate with the receiving parts 21a and 21b. According to
this, air in the receiving parts 21a and 21b is circulated through
each of the air passing holes 51a and 51b of the upper cap 51 and
the insole 15, to thereby discharge air closed inside the shoe 1 to
the outside through air circulation, and removes heat, sweat and
stench generated within the shoe 1, thereby serving to improve the
user's health.
[0037] The screw 57 has the screw shaft 57a on which a male screw
is formed, and the head 57b projected in one side of the screw
shaft 57a, transversely to a shaft line of the screw shaft 57a. The
screw shaft 57a of the screw 57 is screw-coupled with the female
screw 53a of the elevating rod 53 and at the same time the head 57b
of the screw 57 is engaged with the engaging projection 49 of the
spring supporter 43, whereby the lower cap 35 and the upper cap 51
are firmly coupled so as not to be detached from each other. Here,
a pin having a head may be applicable, instead of the screw.
[0038] By the way, a plurality of first air passing holes 15a are
formed on the insole 15 by penetrating it, through which partial
air of the receiving parts 21a and 21b of the mid-sole 13 is
discharged to the inside of the shoe 1. Further, an inlet 16
through which perfume and anti-bacteria agent are injected into an
auxiliary receiving part 25 of the mid-sole 13 is formed on the
insole 15, by penetrating it.
[0039] On one side of the shoe 1 according to the present invention
is formed an air discharging passage 67 to communicate mutually the
receiving parts 21a and 21b with the outside of the outsole 11,
through which partial air of the receiving parts 21a and 21b are
discharged outwardly to the outsole 11.
[0040] On the air discharging passage 67 is provided an air check
valve 71 to prevent air discharged to the outside through the air
discharging passage 57 from flowing backward.
[0041] Referring to FIG. 5, the air check valve 71 comprises a
receiving part cap 73 formed with an inlet hole 73a through which
the partial air of the receiving parts 21a and 21b flows into the
air discharging passage 67, an external cap formed with an exhaust
hole 75a through which the air within the air discharging passage
67 is exhausted to the outside of the outsole 11, an
opening/closing rod 77 to open and close the inlet hole 73a,
provided between the receiving part cap 73 and the external cap 75,
being contacted with and separated from the receiving part cap 73,
and a valve spring to provide a predetermined degree of elasticity
in order to allow the opening/closing rod 77 to be closely
contacted with the receiving part cap 73.
[0042] The receiving part cap 73 is detachably screw-coupled with
the air discharging passage 67. The inner circumferential face of
the receiving part cap 73 is shaped with a cone in section, and is
depressed.
[0043] One end of the opening/closing rod 77 takes the shape of a
cone in section, being contacted with or separated from the inner
circumferential face of the receiving part cap 73.
[0044] The valve spring 79 consists of a coil spring, elastically
supporting the opening/closing rod 77 and the external cap 75.
[0045] With this configuration, the air check valve 71 can more
effectively relieve the shock power transferred to the user's foot,
together with the cushion support parts 31a and 31b. Also, air
closed within the shoe 1 is discharged to the outside through air
circulation and heat, sweat and stench generated inside the shoe 1
are removed, thereby enhancing the user's health.
[0046] Operations of the shoe 1 according to the present invention
will be described.
[0047] Whenever the shoe 1 contacts the ground under the condition
that a user is wearing it, the shock power resulting from the load
is transferred to the shoe 1.
[0048] The shock power due to the load is transferred to the
cushion support parts 31a and 31b of the receiving parts 21a and
21b respectively, the upper caps 51 of the cushion support parts
31a and 31b are squeezed downward due to the pressure applied
thereto, and a spacing between the upper cap 51 and the lower cap
35 is narrowed at the pressing point, whereby the force of
compression is applied to air of the receiving parts 21a and 21b.
The compressed air is discharged to the outside of the shoe 1
through the air discharging passage 67, along with the perfume and
anti-bacteria agent received within the auxiliary receiving part
25, or inside the shoe 1 through the first air passing holes 15a of
the insole 15. Air of the receiving part 21a provided in the toe
portion flows into the receiving part 21b provided in the heel
portion through the grooves 23, along with the perfume and
anti-bacteria agent received in the auxiliary receiving part 25 and
then discharged to the outside of the shoe 1 through the air
discharging passage 67, or into the shoe 1 through the first air
passing holes 15a of the insole 15.
[0049] As illustrated in FIG. 6, the partial air of the receiving
parts 21a and 21b flows into the air discharging passage 67 by
moving the opening/closing rod 77 which closes the inlet hole 73a,
being closely contacted with the receiving part cap 73 while it
flows into the air discharging passage 67, toward the external cap
75. The air flowing into the air discharging passage 67 is
exhausted to the outside of the outsole 11 through the air exhaust
hole 75a of the external cap 75. According to this, the partial air
of the receiving parts 21a and 21b is discharged to the outside of
the shoe 1 through the air discharging passage 67 by way of the air
check valve 71, thereby more effectively relieving the shock power
transferred to the user's foot.
[0050] Where the shock power is not transferred to the shoe 1, that
is, the shock power due to the load is not applied to the cushion
support parts 31a and 31b, a predetermined spacing between the
upper cap 51 and the lower cap 35 is maintained owing to the
elasticity of the springs 33 of the cushion support parts 31a and
31b, whereby the cushion support parts 31a and 31b are restored to
the original state.
[0051] The opening/closing rod 77 moves toward and closely contacts
the receiving part cap 73 due to the elasticity of the valve spring
79, thereby closing the inlet hole 73a as illustrated in FIG. 5. At
this time, no foreign matters from the outside are inserted into
the receiving parts 21a and 21b by way of the air discharging
passage 67.
[0052] As described above, by providing cushion support parts to
relieve shock power applied to the user's foot, receiving parts to
receive the cushion support parts, an air discharging passage
through which partial air of the receiving parts is discharged
toward the outside of the outsole, and an air check valve to
prevent air discharged to the outside through the air discharging
passage from flowing backward, the shock power transferred to the
user's foot is effectively relieved, the feeling of wearing the
shoes is enhanced, air closed within the shoe is discharged to the
outside through air circulation, and heat, sweat and stench
generated within the shoe are removed, thereby serving to enhance
the user's health.
[0053] FIGS. 7 and 8 illustrate cushion support parts of a shoe
according to another exemplary embodiment of the present invention.
Referring to these figures, cushion support parts 31a' and 31b' of
the shoe according to another exemplary embodiment of the present
invention, differently from the above-described exemplary
embodiment, comprises a plurality of springs 33, a lower cap 35 to
support one end of each spring 33, being received in the receiving
parts 21a and 21b, a upper cap 51 disposed oppositely to the lower
cap 35, between which the spring 33 is positioned, and a clip 59
coupled with a spring supporter 43, to thereby interconnect the
lower cap 35 and the upper cap 51.
[0054] The lower cap 35 comprises a planar shaped main body 37, and
a plurality of spring supporters 43 to support one end of the
spring 33, being coupled with the main body 37.
[0055] On the plane of the main body 37 directed toward the bottoms
of the receiving parts 21a and 21b are formed passing holes 39
through which the spring supporters 43 penetrate. On the
circumference of each passing hole 39 are formed engaging holes 41
into which engaging projections 45 of the spring supporter 43 are
inserted for engagement.
[0056] The spring supporter 43 has substantially an inverse
U-shaped section, being mounted on the main body 37 in such a
manner that it is projected toward the upper cap 51. On the outer
circumference of the spring supporter 43 is mounted one end of the
spring 33, and engaging projections 45 inserted into and engaged
with the engaging holes 41 of the lower cap 35 are formed on the
circumference of an opening in the lower portion of the spring
supporter 43. In addition, a passing hole 47 passing through a main
body 61 of the clip 59 to be described later is formed on the upper
portion of the spring supporter 43, and engaging hooks 49 engaged
with the engaging projections 63 of the clip 59 to be described
later are formed on the circumference of the passing hole 47.
[0057] Clip coupling holes 55 through which the main body 61 of the
clip 59 passes for coupling, which correspond to the passing holes
37 of the spring supporter 45, are formed on the upper cap 51 by
penetrating it.
[0058] The clip 59 comprises a rod-shaped main body 61 whereby the
other end of the spring 33 is supported, engaging projections 63,
projected on one end of the main body 61 transversely to an axial
line of the main body 61, being engaged with the engaging hooks 49
of the spring supporter 43, and a flange 65 projected on the other
end of the main body transversely to the axial line of the main
body 61, to support the main body 61 to the upper cap 51.
[0059] According to this, the main body 61 of the clip 59 passes
through the clip coupling holes 55 of the upper cap 51 and the
passing holes 47 of the spring supporter 45 and at the same time
the engaging projections 63 of the clip 59 are engaged with the
engaging hooks 49 of the spring supporter 43, whereby the lower cap
35 and the upper cap 51 are firmly coupled, thereby preventing them
from being detached from each other.
