Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a water-resisting shoe, and
more particularly to a shoe that has a water-tight layer secured
under a vamp of the shoe to avoid water permeating inside the shoe
so as to keep an inner portion of the shoe completely dry for a
long period of time on wet-land.
[0003] 2. Description of Related Art
[0004] When people walk on wet-land or snow covered land, water
will permeate the shoe body and then wet people's feet. Therefore,
people feel uncomfortable because of the damp shoes and their feet
are easily exposed to fungi or become frostbitten at low
temperature. In particular, the fungi can aggravate existing foot
injuries by causing ulcers, etc.
[0005] With reference to FIG. 4, a body of a conventional
water-resisting shoe is composed of a vamp (50), a sock lining
(60), and a sole (70).
[0006] The vamp (50) is combined with an upper portion of the sock
lining (60) and the sole (70) is firmly secured with a lower
portion of the sock lining (60), therefore, the sock lining (60) is
enclosed inside the shoe body.
[0007] The sock lining (60) is made of cloth with a waterproof
membrane (61) adhering on one side of the sock lining (60). The
cloth is cut out pieces and then sewing together to compose in a
shape of shoe and the pieces are tailored into the sock lining
(60), wherein the waterproof membrane (61) is constructed on an
outside of the sock lining (60) and combined with the sole (70) so
as to resist water permeability.
[0008] Although the sock lining (60) is protected by the waterproof
membrane (61) to resist water, seams (62) caused from sewing still
allow water to permeate into the inner portion of the shoe body.
Therefore, manufacturers use multiple adhesive tapes (65) which are
water-resistant to adhere on the seam (62) and seal up the seam
(62) to enhance the water-tight efficiency of the conventional
water-resisting shoe.
[0009] However, two drawbacks of the conventional water-resisting
shoe still exist which are as follow:
[0010] 1. Adhering the adhesive tapes (65) is an extra process in
manufacturing the water resisting shoe and that wastes time as well
as adding to the manufacture cost. Additionally, the rate of
defective product increases when the adhesive tapes (65) do not
adhere to the exact places of the seam (62) or do not adhere on the
seam tightly.
[0011] 2. The water-resisting efficiency of-the shoe body is not
endurable because the adhesive tapes (65) are glued on the sock
lining (60) and effectiveness of the adhesive tapes (65) and the
anti-water membrane (61) will deteriorate after the conventional
water-resisting shoe has been wetted for a long time. Accordingly,
water will then permeate into the inner portion of the shoe
body.
[0012] Therefore, the present invention has arisen to mitigate
and/or obviate the drawbacks of the conventional water-resisting
shoe.
SUMMARY OF THE INVENTION
[0013] The main objective of the present invention is to provide a
water-resisting shoe with a waterproof cover in one piece whereby
the shoe has endurable and complete water-resisting efficiency and
is inexpensive to manufacture.
[0014] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0015] FIG. 1 is an exploded perspective view of a water-resisting
shoe in accordance with the present invention;
[0016] FIG. 2 is a side cross-sectional view of the water-resisting
shoe in assembly;
[0017] FIG. 3 is a flow chart of manufacturing the water-resisting
shoe in accordance with the present invention; and
[0018] FIG. 4 is an exploded perspective view of a conventional
water-resisting shoe.
DETAILED DESCRIPTION OF THE INVENTION
[0019] With reference to FIGS. 1 and 2, a water-resisting shoe is
composed of a vamp (10), a soft sock lining (20), a waterproof
cover (30), and a sole (40).
[0020] The vamp (10) has an opening for access by a foot and is
combined with the sole (40) to form a shoe body with an inner
space. The waterproof cover (30) is combined with the sock lining
(20) to compose a middle layer, and then the middle layer is set
inside of the inner space of the shoe body.
[0021] The waterproof cover (30) is evenly adhered by an inner
surface to an outside face of the sock lining (20) and also adhered
at lower portion of an outer surface to the sole (40).
[0022] The procedures of the manufacturing the water resisting shoe
are shown in FIG. 3.
[0023] Combining the vamp (10) and the sock lining (20): the vamp
(10) has an opening for access by a foot and is combined with the
sock lining (20) at edges of the opening by gluing or sewing;
[0024] Putting a shoe last (not shown) into the sock lining (20):
the shoe last (not shown) is inserted into the sock lining (20) to
prop up the sock lining (20) inside the inner space of the shoe
body.
[0025] Combining the waterproof cover (30) in one piece with the
sock lining (20): the waterproof cover (30) is propped up and
covers the sock lining (20) to construct a middle layer. Because
the shoe last supports the sock lining (20), the waterproof cover
(30) is evenly adhered to the sock lining (20).
[0026] Gluing the waterproof cover (30) to combine with the vamp
(10): the waterproof cover (30) is glued at an upper portion
thereof to combine with the vamp (10) and ensure that the
waterproof cover (30) and the vamp (10) are completely and smoothly
combined with each other.
[0027] Combining the sole (40) with the waterproof cover (30) and
the vamp (10): finally, the sole (40) is glued and adhered to
bottom edges of the vamp (10) and adhered selectively to a lower
portion of the waterproof cover (30) so that the shoe body is
completed.
[0028] Additionally, the waterproof cover (30) is optionally
selected from soft polymer materials such as natural rubber,
polyethylene (PE), polypropylene (PP), polycarbonate (PC). The
polymer materials are liquid and constructed to form the waterproof
cover (30) by injecting molding or coating on a shoe mold, wherein
the waterproof cover (30) is of a single-piece construction without
any seams. Natural rubber is the preferred material of the
waterproof cover (30) because it has excellent elasticity so as to
be easily propped up to cover the sock lining (20).
[0029] The sock lining (20) is made of some soft material such as
cloth to make the water-resisting shoe comfortable when people wear
the shoe. However, it is easily understood that the sock lining
(20) in the shoe body can be eliminated, and the water-resisting
efficiency of the shoe body is still maintained.
[0030] According to the above description, the waterproof cover
(30) is of one-piece construction without any seams and completely
sleeves around the sock lining (20). Therefore, the water-resisting
shoe is endurable and there is no chance for water to permeate into
the inner portion of the shoe body so that feet wearing the
water-resisting shoe can keep dry for long time on wet-land and
even keep warm on snow covered land.
[0031] Besides, in manufacturing procedures, the waterproof cover
(30) is only sleeved on the sock lining (20) by selectively gluing
or not gluing. The adhesive tapes (65) are eliminated so that the
procedures of making the water resisting shoe are simplified and
the potential defective product rate caused from mis-attachment of
the adhesive tapes (65) is eliminated. Although the invention has
been explained in relation to its preferred embodiment, it is to be
understood that many other possible modifications and variations
can be made without departing from the spirit and scope of the
invention as hereinafter claimed.
