Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a shoe structure and, more
particularly, to a waterproof shoe structure.
2. Description of the Related Art
[0002] A conventional waterproof shoe structure 60 in accordance
with the prior art shown in FIGS. 8 and 9 comprises a sole, a vamp
mounted on the sole, a covering layer 61 mounted on the sole, and
an inner bottom layer 62 mounted on the sole. The covering layer 61
has multiple through holes 611. The inner bottom layer 62 has
multiple vent holes 621. A plurality of air channels 63 are formed
between the covering layer 61 and the inner bottom layer 62. The
hot wet air in the shoe structure is introduced through the vent
holes 621, the air channels 63 and the through holes 611 and are
drained outward into the ambient environment, thereby providing an
aerating function. However, the through holes 611 and the covering
layer 61 are located at the same horizontal plane, so that the
rainwater easily infiltrates through the through holes 611 into the
inner space of the vamp. Thus, it is necessary to provide the inner
bottom layer 62 for forming the air channels 63 to guide the
rainwater, and to drain the rainwater outward from the through
holes 611 of the covering layer 61, thereby complicating the
manufacturing procedures, and thereby increasing the cost of
fabrication
BRIEF SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
a waterproof shoe structure having breathable and waterproof
functions.
[0004] In accordance with the present invention, there is provided
a shoe structure comprising a sole, a vamp mounted on the sole, and
a waterproof lining mounted on the vamp. The vamp is provided with
a plurality of vent holes. The waterproof lining has a surface
provided with a plurality of convex portions and a plurality of
concave portions between the convex portions. Each of the convex
portions is higher than each of the concave portions. Each of the
convex portions is provided with a through hole connected to each
of the vent holes of the vamp. The through hole of each of the
convex portions and each of the vent holes of the vamp are
integrated to connect an inner space of the vamp to an ambient
environment. When rainwater drops, the rainwater directly flows
down from the convex portions to the concave portions of the
waterproof lining, without staying on the convex portions. When the
rainwater drops onto the through hole of each of the convex
portions, the rainwater does not enter the through hole of each of
the convex portions by a capillary action. When the vamp is
compressed by an external force, air in the inner space of the vamp
is forced to flow through each of the vent holes of the vamp and
the through hole of each of the convex portions, and is drained
outward from the through hole of each of the convex portions into
the ambient environment. When the vamp is released and restored to
an original state after the external force disappears, the air from
the ambient environment is introduced through the through hole of
each of the convex portions and each of the vent holes of the vamp
into the inner space of the vamp.
[0005] Preferably, each of the convex portions has a semispherical
shape.
[0006] Preferably, the through hole of each of the convex portions
is disposed at a vertical state.
[0007] Preferably, the through hole extends downward from a central

[0011] Preferably, the waterproof lining is mounted on a
raincoat.
[0012] According to the primary advantage of the present invention,
the shoe structure has waterproof and ventilating functions by
provision of the convex portions of the waterproof lining.
[0013] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0023] Referring to the drawings and initially to FIGS. 1 and 2, a
shoe structure 10 in accordance with the preferred embodiment of
the present invention comprises a sole 11, a vamp 12 mounted on the
sole 11, and a waterproof lining 13 mounted on the vamp 12.
[0024] The vamp 12 is provided with a plurality of vent holes
121.
[0025] The waterproof lining 13 has a surface provided with a
plurality of convex portions 131 and a plurality of concave
portions between the convex portions 131. Each of the convex
portions 131 has various models. Each of the convex portions 131 is
higher than each of the concave portions. Each of the convex
portions 131 is provided with a through hole 132 connected to each
of the vent holes 121 of the vamp 12. The through hole 132 of each
of the convex portions 131 and each of the vent holes 121 of the
vamp 12 are integrated to connect an inner space of the vamp 12 to
an ambient environment, to provide a ventilating effect to the shoe
structure 1.
[0026] In the preferred embodiment of the present invention, each
of the convex portions 131 has a semispherical shape.
[0027] In the preferred embodiment of the present invention, the
through hole 132 of each of the convex portions 131 is disposed at
a vertical state.
[0028] In the preferred embodiment of the present invention, the
through hole 132 extends downward from a central position of a top
face of each of the convex portions 131.
[0029] In the preferred embodiment of the present invention, the
through hole 132 of each of the convex portions 131 has a small
diameter.
[0030] In the preferred embodiment of the present invention, each
of the vent holes 121 extends through a whole thickness of the vamp
12, and the through hole 132 extends through a whole thickness of
each of the convex portions 131.
[0031] In practice, referring to FIG. 3 with reference to FIGS. 1
and 2, when the rainwater drops, the rainwater directly flows down
from the convex portions 131 to the concave portions of the
waterproof lining 13, and will not stay on the convex portions 131.
In addition, when the rainwater drops onto the through hole 132 of
each of the convex portions 131, the rainwater does not enter the
through hole 132 of each of the convex portions 131 by the
capillary action which is an interaction of a surface tension
(cohesion) and an adhesion. In such a manner, when the liquid
touches the solid face, the molecule of the liquid (or the
rainwater) and the molecule of the solid face (or the convex
portions 131) produce an adhesion. When the adhesion between the
liquid and the solid face is greater than the cohesion (the surface
tension) of the liquid, the capillary action is produced, and the
liquid is distributed on the solid face, so that the rainwater
directly flows down along the convex portions 131 and does not
infiltrate into the through hole 132 of each of the convex portions
131. Thus, the vamp 12 has a waterproof function by provision of
the convex portions 131 of the waterproof lining 13.
[0032] Referring to FIG. 4 with reference to FIGS. 1 and 2, when
the wearer is moving, the vamp 12 is moved, and the waterproof
lining 13 is moved with the vamp 12. When the vamp 12 is compressed
by an external force, the air in the inner space of the vamp 12 is
forced to flow through each of the vent holes 121 of the vamp 12
and the through hole 132 of each of the convex portions 131, and is
drained outward from the through hole 132 of each of the convex
portions 131 into the ambient environment. When the vamp 12 is
released and restored to the original state after the external
force disappears, the air from the ambient environment is
introduced through the through hole 132 of each of the convex
portions 131 and each of the vent holes 121 of the vamp 12 into the
inner space of the vamp 12. In such a manner, the vamp 12 has a
ventilating function by provision of the convex portions 131 of the
waterproof lining 13, thereby providing a comfortable sensation to
the wearer when wearing the shoe structure 1. Thus, the shoe
structure 10 has waterproof and ventilating functions by provision
of the convex portions 131 of the waterproof lining 13.
[0033] Referring to FIG. 5, a shoe structure 10' in accordance with
another preferred embodiment of the present invention comprises a
sole 11', a vamp 12' mounted on the sole 11', and a waterproof
lining 13' mounted on the vamp 12'. The waterproof lining 13 has a
surface provided with a plurality of convex portions 131' and a
plurality of concave portions between the convex portions 131'.
Each of the convex portions 131' is provided with a through hole
132'. Preferably, each of the convex portions 131' has different
configurations, such as hexagonal shape, conic shape, elliptical
shape, triangular pyramid shape or the like.
[0034] Referring to FIG. 6, a helmet 30 comprises a shell 31 and a
waterproof lining 32 mounted on the shell 31. The waterproof lining
32 has a surface provided with a plurality of convex portions 321
and a plurality of concave portions between the convex portions
321. Each of the convex portions 321 is provided with a through
hole 322. Thus, the helmet 30 has waterproof and ventilating
functions by provision of the convex portions 321 of the waterproof
lining 32.
[0035] Referring to FIG. 7, a raincoat 40 comprises a coat back 41
and a waterproof lining 42 mounted on the coat back 41. The
waterproof lining 42 has a surface provided with a plurality of
convex portions 421 and a plurality of concave portions between the
convex portions 421. Each of the convex portions 421 is provided
with a through hole 422. Thus, the raincoat 40 has waterproof and
ventilating functions by provision of the convex portions 421 of
the waterproof lining 42.
[0036] Accordingly, the shoe structure has waterproof and
ventilating functions by provision of the convex portions of the
waterproof lining.
[0037] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the scope
of the invention.
