Description
FIELD OF THE INVENTION
[0001] The present invention relates to ventilated shoes and more
particularly to a pair of ventilated shoes each having independent
fresh air inflow path and foul air outflow path such that
circulating fresh air in the shoe and driving foul air out of the
shoe can be done in a cycle of lifting the foot and setting the
foot down.
BACKGROUND OF THE INVENTION
[0002] A well known ventilated shoe is shown in FIG. 1. The shoe 10
comprises an outsole 11, an insole 12, a vamp 13, and a hollow heel
14. The heel 14 is made of plastic material. An enclosed bladder 15
is provided in the heel 14. A curved flow line of air 16 is formed
on the outsole 11. The flow line of air 16 comprises a plurality of
apertures 161. The flow line of air 16 is in fluid communication
with the bladder 15. An air inflow line 17 is extended from the
bladder 15. The air inflow line 17 has a check valve 171 and an
outlet 172 at an open end. Fresh air is sucked into the air inflow
line 17 through the outlet 172 and the check valve 171. The outlet
172 of the air inflow line 17 is connected to a hole 141 at one
side of the heel 14. Moreover, a plurality of close apertures 121
arranged in rows and columns are formed on the insole 12.
[0003] Thus, fresh air is sucked into the bladder 15 through the
air inflow line 17 when the foot lifts. Next, fresh air in the
bladder 15 is compressed and driven out to flow to various parts in
the shoe 10 through the apertures 161 of the flow line of air 16
and the apertures 121 of the insole 12 when the foot sets down. As
a result, the person can feel a degree of comfort on his/her
foot.
[0004] However, the prior art suffered from the following
disadvantage. The outlet 172 of the air inflow line 17 of the shoe
10 is connected to the hole 141 at one side of the heel 14. As
such, water may flow into the bladder 15 via the hole 141 at one
side of the heel 14 and the air inflow line 17 when a person
wearing the shoes 10 walks in a rainy or snowy day. As an end, all
parts in the shoes 10 are wet. This can cause great discomfort to
the person. Thus, the need for improvement exists.
SUMMARY OF THE INVENTION
[0005] After considerable research and experimentation, a novel
ventilated shoe with independent fresh air inflow path and foul air
outflow path according to the present invention has been devised so
as to overcome the above drawback (e.g., water may flow into the
shoe to moisten its internal parts) of the prior art.
[0006] It is an object of the present invention to provide a
ventilated shoe comprising a hollow heel formed of plastic
material, the heel comprising an enclosed bladder including a
longitudinal, central divider for dividing the bladder into a left
bladder section and a right bladder section wherein the left
bladder section includes a first check valve and the right bladder
section comprises a second check valve; an outsole; a vamp
comprising a blood vessel-like line of fresh air and a blood
vessel-like line of foul air formed in left and right portions of
the vamp above the outsole respectively wherein the line of fresh
air is connected to the left bladder section, the line of foul air
is connected to the right bladder section, a first check valve is
formed between the line of fresh air and the left bladder section,
and a second check valve is formed between the line of foul air and
the right bladder section; an insole; an inflow hose provided
proximate a left side of the shoe, the inflow hose connected to the
left bladder section; and an outflow hose provided proximate a
right side of the shoe, the outflow hose connected to the right
bladder section, wherein in a cycle of lifting a foot wearing the
shoe and setting the foot down external fresh air is adapted to
suck into the left bladder section through the inflow hose prior to
flowing to the parts in the shoe through the line of fresh air; in
the same cycle of lifting the foot and setting the foot down foul
air in the shoe is adapted to suck into the right bladder section
through the line of foul air prior to driving out of the shoe
through the outflow hose, and by repeating the cycle, fresh air is
adapted to continuously suck into the shoe via the left bladder
section and foul air is adapted to continuously drive out of the
shoe via the right bladder section so as to bring a degree of
comfort to the foot.
[0007] It is another object of the present invention to provide a
deodorant chamber at the same side as the inflow hose in the shoe,
and in the cycle of lifting the foot and setting the foot down
fresh air along with pleasant odor emitted from deodorant filled in
the deodorant chamber is adapted to suck into the left bladder
section through the inflow hose prior to flowing to the parts in
the shoe through the line of fresh air for masking unpleasant odor
in the shoe.
[0008] It is a further object of the present invention to form a
plurality of close apertures arranged in rows and columns on the
insole, and the apertures of the insole are adapted to direct fresh
air leaving the left bladder section onto a sole of the foot for
bringing a degree of comfort thereto.
[0009] The above and other objects, features and advantages of the
present invention will become apparent from the following detailed
description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is an exploded view of a prior ventilated shoe;
[0011] FIG. 2 is an exploded view of a ventilated shoe according to
a first preferred embodiment of the invention;
[0012] FIG. 3 is a schematic sectional view of the shoe of FIG. 2;
and
[0013] FIG. 4 is a schematic sectional view of ventilated shoe
according to a second preferred embodiment of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] Referring to FIGS. 2 and 3, a ventilated shoe 20 with
independent fresh air inflow path and foul air outflow path
according to a first preferred embodiment of the invention is
shown. The shoe 20 comprises an outsole 21, an insole 22, a vamp
23, and a hollow heel 24. The heel 24 is made of plastic material.
An enclosed bladder 25 is provided in the heel 24. A longitudinal,
central divider is provided in the bladder 25 to divide the bladder
25 into a left bladder section 251 and a right bladder section 253.
The left bladder section 251 comprises a first check valve 255. The
right bladder section 253 comprises a second check valve 257. A
line of fresh air 26 and a line of foul air 27 are formed in left
and right portions of the vamp 23 above the outsole 21
respectively. A plurality of apertures 261 are formed in the line
of fresh air 26. The line of fresh air 26 is detachably connected
to the first check valve 255. Once connected, air can be
communicated from the left bladder section 251 of the bladder 25 to
the line of fresh air 26. Likewise, a plurality of apertures 271
are formed in the line of foul air 27. The line of foul air 27 is
detachably connected to the second check valve 257. Once connected,
air can be communicated from the right bladder section 253 of the
bladder 25 to the line of foul air 27.
[0015] Referring to FIGS. 2 and 3 again, an inflow hose 28 is
provided in the shoe 20 proximate its left side and an outflow hose
29 is provided in the shoe 20 proximate its right side. The inflow
hose 28 is connected to the left bladder section 251 and the inflow
hose 28 has an upper opening. External fresh air can be sucked into
the left bladder section 251 through the inflow hose 28 when the
foot lifts. Next, fresh air in the left bladder section 251 is
compressed and driven out to flow to various parts in the shoe 20
through the line of fresh air 26 and the apertures 261 of the line
of fresh air 26 when the foot sets down. Similarly, the outflow
hose 29 is connected to the right bladder section 253 and the
outflow hose 29 has an upper opening. Foul air in the shoe can be
sucked into the right bladder section 253 through the line of foul
air 27 and the apertures 271 of the line of foul air 27 when the
foot lifts. Next, foul air in the right bladder section 253 is
compressed and driven out of the shoe through the outflow hose 29
when the foot sets down.
[0016] Referring to FIGS. 2 and 3 again, by configuring as above,
in a cycle of lifting the foot and setting the foot down external
fresh air can be sucked into the left bladder section 251 through
the inflow hose 28 prior to flowing to various parts in the shoe
through the line of fresh air 26. Likewise, in the same cycle of
lifting the foot and setting the foot down foul air in the shoe can
be sucked into the right bladder section 253 through the line of
foul air 27 prior to driving out of the shoe through the outflow
hose 29. By repeating the above cycle, external fresh air can be
continuously sucked into the shoe via the left bladder section 251
and internal foul air can be continuously driven out of the shoe
via the right bladder section 253. As a result, the person can feel
a degree of comfort on his/her foot.
[0017] Referring to FIGS. 2 and 3 again, in the invention a
deodorant chamber 31 is provided at the same side as the inflow
hose 28 in the shoe 20. As such, in a cycle of lifting the foot and
setting the foot down external fresh air along with the pleasant
odor emitted from the deodorant in the deodorant chamber 31 can be
sucked into the left bladder section 251 through the inflow hose 28
prior to flowing to various parts in the shoe through the line of
fresh air 26. As a result, unpleasant odor in the shoe can also be
masked.
[0018] Referring to FIGS. 2 and 3 again, a plurality of close
apertures 221 arranged in rows and columns are formed on the insole
22 of the shoe 20. The apertures 221 of the insole 22 can direct
fresh air leaving the left bladder section 251 onto the sole. As a
result, the person can feel a degree of comfort on his/her
foot.
[0019] Referring to FIGS. 2 and 3 again, the insole 22 of the shoe
20 is formed of a ventilated material. This enables fresh air
leaving the left bladder section 251 to pass the insole 22 prior to
directing onto the sole. As a result, the person can feel a degree
of comfort on his/her foot.
[0020] Referring to FIGS. 2 and 3 again, each of the line of fresh
air 26 and the line of foul air 27 is implemented as a blood
vessel-like member formed in left and right portions of the vamp 23
above the outsole 21 respectively.
[0021] Referring to FIG. 4, in a second preferred embodiment of the
invention a transverse, central divider is provided in the bladder
25 to divide the bladder 25 into an upper bladder section 41 and a
lower bladder section 43.
[0022] In view of the above, it is clear that the inflow hose 28 is
provided in the shoe proximate its left side and the outflow hose
29 is provided in the shoe proximate its right side. Each of the
inflow hose 28 and the outflow hose 29 has an upper opening. As
such, water is prevented from flowing into the shoe 20 via the
inflow hose 28 or the outflow hose 29 when a person wearing the
shoes 20 walks in a rainy or snowy day. This characteristic is
unique and is an advantageous elimination of the prior art
drawback. By implementing the independent fresh air inflow path and
foul air outflow path of the invention, external fresh air can be
quickly continuously sucked into the shoe and internal foul air can
also be quickly continuously driven out of the shoe while walking.
As a result, the person can feel a degree of comfort on his/her
foot.
[0023] While the invention herein disclosed has been described by
means of specific embodiments, numerous modifications and
variations could be made thereto by those skilled in the art
without departing from the scope of the invention set forth in the
claims.
