DETAILED DESCRIPTION
[0016] Before the present disclosure is described in greater detail
with reference to the accompanying embodiments, it should be noted
herein that like elements are denoted by the same reference
numerals throughout the disclosure.
[0017] Referring to FIGS. 1 to 6, a moisture-permeable waterproof
shoe according to the first embodiment of the present disclosure is
shown to comprise an upper 10, an inner sleeve unit 20, a sole 30
and an adhesive layer 40.
[0018] The upper 10 is made of a jacquard woven fabric, and has an
inner surface 11, a top open end 12 and a bottom end 13 defining an
opening 131.
[0019] The inner sleeve unit 20 has an inner sleeve body 21 and a
connecting layer 22. The inner sleeve body 21 is filed to the inner
surface 11 of the upper 10, and has a bottom portion 211 (see FIG.
2) that is not adhered to the inner surface 11 of the upper 10 and
that is immediately adjacent to the opening 131. The inner sleeve
body 21 includes a three-dimensional sleeve portion 23, and a
moisture-permeable waterproof membrane 24 attached to an outer
surface of the three-dimensional sleeve portion 23. The
three-dimensional sleeve portion 23 includes two layered structures
231 connected to and cooperating with each other to define a foot
space 25 having a top open end and a bottom closed end for
accommodating a user's foot. Each layered structure 231 includes an
outer fabric layer 232, a lining fabric layer 233, and an
intermediate foam layer 234 fixed between the outer fabric layer
232 and the lining fabric layer 233. In this embodiment, as shown
in FIG. 4, each layered structure 231 has the shape of a shoe half,
and has a curved top edge 235, and a peripheral edge 236 extending
between two opposite ends of the top edge 235. The peripheral edges
236 of the layered structures 231 are stitched to each other.
[0020] The connecting layer 22 of this embodiment is an adhesive
layer which fixedly adheres the moisture-permeable waterproof
membrane 24 to the inner surface 11 of the upper 10.
[0021] In this embodiment, the moisture-permeable water-proof
membrane 24 covers the outer fabric layers 232 of the layered
structures 231, and is made of polyurethane (PU), but is not
limited thereto. In other embodiment, the moisture-permeable
waterproof membrane 24 may be made of a material selected from a
group consisting of thermoplastic polyurethane (TPU), polyethylene
(PE) or polytetrafluoroethylene (PTFE). Further, a water pressure
resistance of the moisture-permeable waterproof membrane 24 using
the standard test method of the Japanese regulation JIS L1092B is
not less than 3000 mm H.sub.2O, and a moisture permeability thereof
using the standard test method of the Japanese regulation JIS
L1099B1 is not less than 3000 g/m.sup.2/24 hr. Hence, the
moisture-permeable water-proof membrane 24 has a waterproof effect
and a moisture-permeable effect.
[0022] It is worth to mention herein that the inner sleeve body 21
may be formed by a dipping process or a spraying process. In the
dipping process, the three-dimensional sleeve portion 23 is first
sleeved on a shoe last 100, after which it is dipped into a
moisture-permeable waterproof resin bath for a certain period of
time, so that the moisture-permeable waterproof resin is attached
to the outer fabric layers 232 of the layered structures 231 of the
three-dimensional sleeve portion 23; then, the three-dimensional
sleeve portion 23 is removed from the resin bath, and the shoe last
100 is activated to rotate about its axis, so that the attached
moisture-permeable waterproof resin on the three-dimensional sleeve
portion 23 is formed into the moisture-permeable waterproof
membrane 24 having a uniform thickness; and finally, the
three-dimensional sleeve portion 23 together with the shoe last 100
is placed in an oven (not shown), and is heated at a predetermined
temperature for a predetermined time to dry and cure the
moisture-permeable waterproof membrane 24. In the spraying process,
a moisture-permeable waterproof resin solution is sprayed onto an
outer surface of the outer fabric layers 232 of the layered
structures 231 of the three-dimensional sleeve portion 23.
[0023] Referring to FIGS. 7 and 8, in other variation of this
embodiment, the inner sleeve unit 20 may further include a
waterproof strip 26. The waterproof strip 26 is fixedly connected
to an outer surface of the moisture-permeable waterproof membrane
24, and extends along the peripheral edges 236 of the layered
structures 231 so as to cover a stitching junction of the layered
structures 231, thereby enhancing a waterproof effect of the
layered structures 231 at the stitching junction thereof.
[0024] The sole 30 has a top surface 31 fixedly connected to the
bottom end 13 of the upper 10 and the bottom portion 211 of the
inner sleeve body 21.
[0025] The adhesive layer 40 fixedly adheres the top surface 31 of
the sole 30 to the bottom end 13 of the upper 10 and the bottom
portion 211 of the inner sleeve body 21.
[0026] With reference to FIGS. 2 and 4, a brief description of a
method of making the first embodiment is provided below.
[0027] The shoe last 100 is first inserted into the foot space 25
of the inner sleeve body 21, after which the outer surface of the
moisture-permeable waterproof membrane 24 is sprayed (or coated)
with adhesive. Next, the inner surface 11 of the upper 10 is
sprayed (or coated) with adhesive, and the upper 10 is sleeved on
the inner sleeve body 21. The assembly of the upper 10 and the
inner sleeve body 21 is then heated and pressed to fixedly adhere
the upper 10 to the inner sleeve body 21. After the assembly of the
upper 10 and the inner sleeve body 21 is cooled, the sole 30 is
fixedly adhered to the bottom end 13 of the upper 10 and the bottom
portion 211 of the inner sleeve body 21 by adhesive. Finally, the
shoe last 100 is removed from the assembly.
[0028] From the foregoing, the advantages of this disclosure can be
summarized as follows:
[0029] 1) Since the moisture-permeable waterproof membrane 24 of
the inner sleeve body 21 completely covers the outer surface of the
three-dimensional sleeve portion 23, in comparison with the prior
art, the moisture-permeable waterproof membrane 24 can effectively
prevent water from the outside to seep into the three-dimensional
sleeve portion 23, thereby achieving a good waterproof effect and
preventing the user's foot from getting wet. Further, the
moisture-permeable waterproof membrane 24 can also prevent entry of
wind into the three-dimensional sleeve portion 23, thereby
achieving a windproof effect and enhancing a warm-keeping
effect.
[0030] 2) The three-dimensional shape of the three-dimensional
sleeve portion 23 is supported by the intermediate foam layers 234
of the layered structures 231 by virtue of the stiffness thereof.
Through this, apart from, supporting the upper 10 so that it will
not collapse inward, insertion of the user's foot into the foot
space 25 can also be facilitated, so that wear of the disclosure is
easy and comfortable.
[0031] 3) The moisture-permeable waterproof membrane 24 of the
inner sleeve body 21 has a waterproof effect and a
moisture-permeable effect. Hence, when the user wears the shoe of
this disclosure, moisture inside the three-dimensional sleeve
portion 23 can be dissipated from the shoe through the
moisture-permeable waterproof membrane 24, so that the user's foot
can be kept dry and comfortable.
[0032] Referring to FIG. 9, the second embodiment of the
moisture-permeable waterproof shoe of this disclosure is shown to
be generally identical to the first embodiment. However, in this
embodiment, the moisture-permeable waterproof shoe further
comprises a tightening unit 50 and a reinforcing layer 60.
[0033] The upper 10 includes a vamp portion 14, and a heel region
15 (see FIG. 1) opposite to the vamp portion 14. The sole 30
includes a sole heel region 32. The tightening unit 50 is disposed
across the vamp portion 14, and is used to tighten the shoe of this
embodiment over the user's foot that is inserted into the foot
space 25. The tightening unit 50 includes a pair of tightening
plates 51 respectively connected to left and right sides of the
sole 30 and abutting against the vamp portion 14, and two
tightening strips 52 interconnecting the tightening plates 51. Each
tightening plate 51 has a connecting end portion 511 connected to
the respective left or right side of the sole 30, and a free end
portion 512 opposite to the connecting end portion 511. The
tightening strips 52 interconnect the free end portions 512 of the
tightening plates 51. It should be noted that the number of the
tightening strip 52 is not limited to what is disclosed herein, and
may be more than two in other embodiment.
[0034] The reinforcing layer 60 is connected to the heel region 15
of the upper 10 and the sole heel region 32 of the sole 30.
[0035] The advantages of the first embodiment can be similarly
achieved using the second embodiment.
[0036] Therefore, the object of the moisture-permeable waterproof
shoe of this disclosure can indeed be achieved.
[0037] While the disclosure has been described in connection with
what are considered the exemplary embodiments, it is understood
that this disclosure is not limited to the disclosed embodiments
but is intended to cover various arrangements included within the
spirit and scope of the broadest interpretation so as to encompass
all such modifications and equivalent arrangements.
