Shoe sole with air ventilation device
Abstract
A show sole includes a bellows portion located at the heel
section of the sole and compressible space is defined in the
bellows portion. A spring unit is located in the compressible
space. At least one escape hole is defined through a wall of the
bellows portion. An insole is mounted to the sole and seals the
compressible space. Multiple pipes extend from the compressible
space and each has two open ends. One of the two open ends of each
pipe communicates with the compressible space. When the
compressible space is compressed, the air in the compressible space
flows through the pipes and the escape hole. When the force is
released from the compressible space, the air outside the shoe is
sucked into the compressible space.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a shoe having an air
ventilation device in the sole so as to remove heat and moisture
from the wearer's foot.
BACKGROUND OF THE INVENTION
[0002] A conventional shoe is designed for protection the foot of
the wearer when walking or running and the conventional shoes
include a vamp connected to the outsole to form an enclosed space
in which the wearer's foot is received. After a period of time of
use, the air in the space cannot escape from the shoe and the
wearer's sweat is mixed with the hot air to cause bad smell. The
hot air further increases reproduction of germs such as fungus
which may cause athlete feet to the wearers. Besides, most of the
conventional shoes do not have proper shock absorbing device and
the impact is directly transferred the wear's ankles. The impact
affects not only the muscles and ankles, but also the spine and
even the brain. Some shoes in the market claim that they have
ventilation system for providing circulation of the air in the
shoes, most of them can only provide weak air flow in the shoes and
the weak air flow cannot achieve the desired purposes.
[0003] The present invention intends to provide a sole of a shoe
and an air ventilation device is located in the sole, the air
ventilation device includes a compressible space at the heel
portion and pipes extend to the front portion of the shoe so as to
bring air to front of the shoe, and at least one escape hole is
defined in the heel portion to allow the air to escape from the
shoe when the compressible space is compressed.
SUMMARY OF THE INVENTION
[0004] The present invention relates to a shoe sole which comprises
a sidewall extending from upward from an outer periphery thereof
and a bellows portion is located at heel section of the sole. A
compressible space is defined in the bellows portion and a spring
unit is located in the compressible space. At least one escape hole
is defined through a wall of the bellows portion. Multiple pipes
extend from the compressible space and each include two open ends,
one of the two open ends of each pipe communicates with the
compressible space.
[0005] The primary object of the present invention is to provide a
shoe sole that can effectively bring moisture out from the interior
of the shoe.
[0006] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is an exploded view to show the shoe sole and the air
ventilation device of the present invention;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Referring to FIGS. 1 and 2, the shoe sole 1 of the present
invention comprises a front section, a middle section and a heel
section. A sidewall extends from upward from an outer periphery
thereof and includes a bellows portion 11 which is located at heel
section of the sole 1. A compressible space 12 is defined in the
bellows portion 11 and a spring unit 13 is located in the
compressible space 12. At least one escape hole 121 is defined
through a wall of the bellows portion 11 and communicates with the
compressible space 12.
[0016] Two pipes 122 extend from the compressible space 12 and each
have two open ends, and one of the two open ends of each pipe 122
communicates with the compressible space 12. In this embodiment,
the sole 1 includes transverse and parallel plates and two passages
are defined perpendicularly through these plates. The pipes 122 are
located within the passages and arranged axially in the sole 1. The
pipes 122 are ended at a front section of the sole 1.
[0017] As shown in FIGS. 3 and 4, an insole 3 is mounted on the
sole 1 and seals the open top of the compressible space 12, and a
vamp 4 is connected to the sole 1 to form a shoe. When walking or
running, the wearer applies a force to compress the spring unit 13
and compresses the compressible space 12, air in the compressible
space 12 escapes from the at least one escape hole 121 and flows
through the two pipes 122. The air flowing out from the pipes 122
keeps the wearer's foot dry.
[0018] As shown in FIGS. 5 and 6, when the force is disappeared,
the spring unit 13 bounces the bellows portion 11 to its original
shape and air outside the shoe is sucked into the compressible
space 12 via the at least one escape hole 121 and the air in the
shoe is sucked via the pipes 122. The moisture is then sucked into
the compressible space 12 and will escape from the at least one
escape hole 121 when the compressible space 12 is compressed
again.
[0019] FIGS. 7 and 8 show the second embodiment of the present
invention wherein the sole 1 comprises a front section, a middle
section and a heel section. The middle section and the heel section
include a top portion 14 and a lower portion 15 extending from the
middle section and a wedge-shaped space 120 is defined between the
top and lower portion 14, 15. The wedge-shaped space 120 is located
at the heel section of the sole 1. Two pipes 122 located axially in
the front section and each have two open ends.
[0020] Two first holes are defined in the conjunction portion of
the top and lower portions 14, 15 and communicate with the pipes
122. A wedge-shaped compressible part 2 is securely engaged with
the wedge-shaped space 120 and includes a hollow interior and
bellows-shaped outside. At least one escape hole 21 is defined
through a wall of the compressible part 2 and communicates with the
hollow interior. A spring unit 22 is located in the compressible
part 2. Two second holes 23 are defined through a front end of the
compressible part 2 and in communication between the two first
holes and the hollow interior. By compressing and bouncing the
wedge-shaped compressible part 2, the air can be ventilated
throughout the shoe.
[0021] The bellows portion 11 assists the deformation of the
compressible space to be compressed to effectively ventilate the
air throughout the shoe. The air in the shoe can be brought out
from the escape hole and the fresh air outside the shoe is sucked
into the shoe to achieve desired ventilation purpose. The spring
unit absorbs the impact from the ground and provides comfortable
wearing. The compressing and bouncing of the spring unit stimulate
the wearer's foot to benefit blood circulation.
[0022] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
