DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Referring to FIGS. 1-4, an improved 3-D shoe with
ventilation according to the present invention is disclosed. As
shown, the 3-D shoe includes a sole having an outsole 10, an air
pad 20, a midsole 30 and an insole 40; wherein the outsole 10 is
composed of a heel section 10a at rear part thereof and a sole
section 10b at front part thereof. A first air compartment 11b
containing a plurality of air ducts 111b is integrally formed at
the sole section 10b of the outsole 10. The midsole 30 is placed
above the outsole 10. The insole 40 is placed above the midsole 30.
The air pad 20 is placed below the insole 40 and above the heel
section 10a of the outsole 10 and provided with an air outlet 21.
The improvement resides in that a second air compartment 11a
containing a plurality of air ducts 111a is formed integrally at
the heel section 10a of the outsole 10. A communicating duct 12 is
defined between the first air compartment 11b and the second air
compartment 11a for communication between the first air compartment
11b and the second air compartment 11a and for communicating with
the air outlet 21 of the air pad 20. In the second air compartment
11a of the outsole 10, a ventilating hole 13 is provided in one of
the air ducts 111a at a lateral side of the outsole 10 in flush
with a bottom surface of the one of the air ducts 111a to
communicate with the ambient. Thus, on repetitive compression of
the air pad 20, the ambient air can be drawn through the
ventilating hole 13 into the air duct 111a and then to the first
air compartment 11b of the heel section 10b via the communicating
duct 12, so as to replace the air within the shoe completely and
thus keep the foot fully dry and let the user feel comfortable.
[0013] As shown in FIG. 1 and FIG. 4, the air ducts 111a of the
second air compartment 11a of the heel section 10a each has a
bottom surface 110, which commences halfway between two lateral
sides of the outsole 10 and goes down to each lateral side. At
least one ventilating hole 13 is provided at one lateral side of
the outsole 10 in flush with the bottom surface, such that water
spreading into the shoe can flow out of the shoe by way of the
downward bottom surface 110 of the air duct 111a through the
ventilating hole 13, so as to keep the interior of the shoe in dry
condition.
[0014] According to the improved 3-D shoe of the present invention,
the outsole 10 defines a concaved space 14 at the heel section 10a.
The concaved space 14 has a shape substantially conforming to the
air pad 20, such that the air pad 20 can be firmly placed over the
outsole 10.
[0015] According to the improved 3-D shoe of the present invention,
the midsole 30 defines an opening 31 at rear part thereof to enable
the air pad 20 to bulge out of the midsole 30. Moreover, the
midsole 30 is provided with a plurality of pores 32 such that the
air circulating within a space between the outsole 10 and the
midsole 30 can flow out through the pores 32.
[0016] As shown in FIG. 1 and FIG. 3, the insole 40 includes a main
body 41 having a plurality of air pockets 42 formed on one side of
the main body. The main body 41 further includes a plurality of
protrusions 43, which are positioned corresponding to the
boundaries of air pockets 42, formed on the other side of the main
body so as to define a plurality of air cells 40a therebetween. The
main body 41 is further provided with a plurality of through holes
44, each being positioned at a junction area to which the
associated protrusions extend, whereby each through hole 44 is
allowed to communicate with adjacent air cells. Furthermore, the
main body 41 is provided with a bulged press portion 45 to be
placed over the air pad 20. Accordingly, when the user is walking,
the air pockets 42 and the bulged press portion 45 can be
compressed to enhance the air ventilation of the shoe. In addition
to the above-mentioned component, other insoles can be employed in
the present invention as well.
[0017] According to the improved 3-D shoe of the present invention,
the primary features reside in that: the first air compartment 11b
containing a plurality of air ducts 111b and the second air
compartment 11a containing a plurality of air ducts 111a are
integrally formed at the sole section 10b and the heel section 10a
of the outsole 10 respectively; and a communicating duct 12 is
defined between the first air compartment 11b and the second air
compartment 11a to enable them to communicate with each other.
Accordingly, the outsole 10 can be integrally manufactured without
combination of separate parts as disclosed in the prior art. Thus,
the manufacturing process can be simplified and the cost can be
reduced. It is believed that the present invention is industrially
applicable and with novel features.
[0018] Although the present invention has been described with a
certain degree of particularity, it is understood that the present
disclosure is made by way of example only and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention hereinafter claimed.
