Description
FIELD OF THE INVENTION
[0001] The present invention relates to insoles, and particular to
an air-ventilating insole, wherein a plurality of spiral springs
are distributed in an air chamber between an upper insole and a
lower insole so as to have a preferred stability. Thereby, the
insole has preferred arrangement of the air ventilating holes so
that the shoe with the insole of the present invention can have
preferred air ventilation effect.
BACKGROUND OF THE INVENTION
[0002] In the prior art shoe with air ventilating function has
pumps or airbags or check valves or air guide tubes, etc. in the
sole of the shoe for controlling air to flow unidirectionally.
Since these devices have a larger volume, if they are installed in
a shoe, other than the strength of the shoe being reduced, the user
will feel uneasy. Thereby, the shoe cannot be washed in water.
[0003] To improve above mentioned defects, in U.S. patent Ser. No.
10/647,571, assigned to the inventor of the present invention, an
air-ventilating insole is developed which can be placed in a shoe
so as to have a preferred effect with a lower cost. In the prior
arts, a plurality of spiral springs with smaller size are used. In
the prior art, the spiral springs have a lateral round positioning
ends. No positioning slots is formed. Thereby, the spiral springs
will swing and vibrate so as to affect the air exchange function.
Furthermore, the adhering structure by the upper insole, lower
insole, and rubber strips to form an air chamber is easy to detach
or destroyed so that air vents out.
SUMMARY OF THE INVENTION
[0004] Accordingly, the primary object of the present invention is
to provide an air-ventilating insole, wherein the air outlets face
upwards. It can be used in cold weather. If it is cold or no
ventilation effect is necessary, the insole can be upside down and
the left insole is exchanged with the right insole so that the air
outlets face downward. As a result air in the air chamber is
hindered in the air chamber. Thus the air chamber is used as an air
inflation pad which has the effect of softness and protection.
[0005] To achieve above objects, the present invention provides an
air-ventilating insole comprises an upper insole; a center of the
upper insole being formed with a receiving groove; an enclosing
frame enclosing the receiving groove; a plurality of U shape
positioning slots being formed on the enclosing frame; a heel
portion of the upper insole being formed with a plurality of air
inlets and a front thenar portion of the upper insole being formed
with a plurality of air outlets; a lower insole located below the
upper insole; an air chamber being formed; a plurality of spiral
springs installed between the upper insole and lower insole; the
spiral springs being installed to the U shape positioning slots of
the enclosing frame; each spiral spring being formed as a truncated
cone and further as the spiral spring is compressed to be on a same
plane; one end of the spiral spring being formed with a U shape
positioning end which is embedded into a respective U shape
positioning slot of the upper insole; a ventilating layer stuck
above the upper insole at a position for contacting the bottom of
the leg; a plurality of air input holes being formed in the
ventilating layer, which are communicated to the air inlets. When
the heel presses upon the insoles, the air inlets of the upper
insole and the air input holes of the ventilating layer will
compress air in the air chamber so as to flow upward to the front
thenar portion of the user's leg.
[0006] Moreover, in the present invention, if it is cold or no
ventilation effect is necessary, the insole can be upside down and
the left insole is exchanged with the right insole so that the air
outlets face downward. As a result air in the air chamber is
hindered in the air chamber. Thus the air chamber is used as an air
inflation pad which has the effect of softness and protection.

DETAILED DESCRIPTION OF THE INVENTION
[0015] In order that those skilled in the art can further
understand the present invention, a description will be described
in the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0016] Referring to FIGS. 1 and 2, the structure of the present
invention is illustrated. The insole 1 of present invention
includes the following elements.
[0017] An upper insole 11 is included. A center of the upper insole
11 is formed with a receiving groove 111. An enclosing frame 112
encloses the receiving groove 111. A plurality of U shape
positioning slots 113 are formed on the enclosing frame 112. A heel
portion of the upper insole 11 is formed with a plurality of air
inlets 114 and a front thenar portion of the upper insole 11 is
formed with a plurality of air outlets 115
[0018] A lower insole 12 is located below the upper insole 11. An
air chamber S is formed by the upper insole 11 and lower insole
12.
[0019] A plurality of spiral springs 14 are installed between the
upper insole 11 and lower insole 12. The spiral springs 14 are
installed to the U shape positioning slots 113 of the enclosing
frame 112. Each spiral spring 14 has an upper plane and a lower
plane a plurality of coils are wound between the upper plane and a
lower plane. Thereby, the spiral spring 14 are formed as a
truncated cone and further the spiral spring 14 can be compressed
to be on a same plane. One end of the spiral spring 14 is formed
with a U shape positioning end 141 which is embedded into a
respective U shape positioning slot 113 of the upper insole 11 as
the upper insole 11 and the lower insole 12 are adhered together.
Thereby, the U shape positioning end 141 can be used to position
the orientation of the spiral spring 14 so as to have the effect of
enhancing the structure of the insole.
[0020] A ventilating layer 13 is stuck above the upper insole 11 at
a position for contacting the bottom of the leg. A plurality of air
input holes 131 are formed in the ventilating layer 13, which are
communicated to the air inlets 114, but no air output holes are
formed on the front thenar portion of the ventilating layer 13 for
communicating the air outlets 115 of the upper insole 11. When the
heel presses upon the insoles, the air inlets 114 of the upper
insole 11 and the air input holes 131 of the ventilating layer 13
will compress air in the air chamber S so as to flow upward to the
front thenar portion of the user's leg.
[0021] Referring to FIGS. 3 and 4, when the user wearing the shoe
with the insole of the present invention walks, the heel of user
treads upon the insole, the air input holes 131 of the ventilating
layer 13 and the air inlets 114 of the upper insole 11 are pressed
by the heel so that the air in the air chamber S is compressed to
flow out from the air outlets 115 of the upper insole 11 and the
ventilating layer 13 to disperse in between the front thenar
portion. When the leg of the user lifts, the air chamber S is
restored by the resilient force of the spiral springs 14 so as to
drive the external air to flow into the air input holes 131 of the
ventilating layer 13 and the air inlets 114 of the upper insole 11.
Therefore, since no air output hole is formed at the ventilating
layer 13 corresponding to the front thenar portion, the compressed
air will not easily flow into the air chamber S. Thereby, air flows
unidirectionally. Thus the air chamber S has saturated cool
air.
[0022] By the continuous treading actions, air within the shoe and
external the shoe displace continuously so that the wet and hot air
in the shoe can be ventilated preferably.
[0023] Referring to FIG. 5, another embodiment of the present
invention is illustrated. The air-ventilating insole 1A: A
ventilating layer 13A adhered to a front end of the receiving
groove 111A of the upper insole 11A; so as to cover the air outlets
115 of the upper insole 11A, no spiral springs are installed upon
the ventilating layer 13A; a plurality of spiral springs 14 are
installed in the heel portion of the receiving groove 111A of the
upper insole 11A. a leather layer or cloth layer 13B being adhered
to the upper insole 11A; the leather layer or cloth layer 13B being
formed with a plurality of air input holes 131 and air output holes
132 which are communicable to the air inlets 114 and air outlets
115 of the upper insole 11A.
[0024] As shown in FIG. 6, the third embodiment of the present
invention is illustrated. A front end of the receiving groove 111
of the upper insole 11 is adhered with a ventilating layer 13A
which only covers the front half of the insole 1 so as to cover the
air outlets 115 of the upper insole 11. A plurality of spiral
springs 14 are installed upon the ventilating layer 13A. so that
the air out of the air chamber S of the upper insole 11 will not
easily return to the air chamber S. Thus air flows
unidirectionally. a plurality of spiral springs 14 are installed in
the heel portion of the receiving groove 111 of the upper insole 11
A leather layer 15 (or cloth layer) is adhered to the upper insole
11. The leather layer or cloth layer 15 is formed with a plurality
of air input holes 151 and air output holes 152 which are
communicable to the air inlets 114 and air outlets 115 of the upper
insole 11 so that cool air is filled in the air chamber S at any
time for air ventilation.
[0025] Thereby, not only the treading force of heel can be buffered
so that the shock of the heel is reduced, but also the wet and hot
air within the shoe can circularly flow with external cool air to
have a preferred air ventilation effect so as to avoid the effect
of infection of bacteria or perspiration or getting foot tinea.
[0026] The advantages of the present invention will be described
herein.
[0027] Since the spiral spring 14 has U shape positioning end 141
to be positioned to the U shape positioning slot 113 of the
enclosing frame 112 of the upper insole 11, by the U shape
structure of the U shape positioning end 141, the U shape
positioning end 141 embedded into the enclosing frame 112 of the
upper insole 11 can be used to determine the orientation of the
spiral spring 14 to prevent the displacement of the spiral spring
14.
[0028] The material of the insole 1 is simple without any check
valve or air guide tube. When the spiral springs 14 are compressed,
the spiral springs 14 will be disposed at the same plane so that it
is light and thin. Thus the user will feel comfortable.
[0029] The air chamber S within the insole 1 can contain more air
so that air ventilation amount is great, which is suitable for
leather shoes, cloth shoes, and other shoes. The insole 1 can be
taken out easily.
[0030] A plurality of small size spiral springs 14 are used to
replace a great spiral spring so that elastic force can be
dispersed and a great resilient force generates. When the insole is
pressed, it can restore easily so as to assure that air is
saturated in the air chamber and the insole 1 will no bend to
destroy the structure thereof.
[0031] The hot and wet air within the shoe can be displaced with
external cool air so as to avoid the effect of infection of
bacteria or perspiration or getting foot tinea. Furthermore, the
force applied to the sole can be buffered and have the effect of
shock absorption.
[0032] Referring to FIG. 7, if it is cold or no ventilation effect
is necessary, the insole 1 can be upside down and the left insole
is exchanged with the right insole (see FIG. 3) so that the air
outlets 115 face downwards. As a result air in the air chamber S is
hindered in the air chamber S. Thus the air chamber S is used as an
air inflation pad which has the effect of softness and
protection.
[0033] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
