Claims
I claim:
1. A waterproof shoe comprises: an outer skin, a lining, and a
waterproof layer disposed between the outer skin and the
lining.
2. The waterproof shoe as claimed in claim 1, wherein the
waterproof layer is a rubber layer.
3. The waterproof shoe as claimed in claim 1, wherein the

Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a waterproof shoe. More
particularly, the present invention relates to a waterproof shoe
which has a rubber layer to prevent water from entering an inner
interior of the waterproof shoe.
[0002] Referring to FIGS. 1, 2 and 2A, a first conventional
waterproof shoe 20' has a synthetic skin 21', a lining 40', and a
twill layer 22' disposed between the synthetic skin 21' and the
lining 40'. Since the synthetic skin 21' is generally made of a
waterproof material, the twill layer 22' need not be made of
waterproof materials. After a long period of usage, water will
enter the first conventional waterproof shoe 20' through
capillarity.
[0003] Referring to FIGS. 3 and 3A, a second conventional
waterproof shoe 20" has an outer skin 21" made of a cattle hide, a
canvas, a flannelette or a fiber fabric, a twill layer 22" disposed
on the outer skin 21", a polyurethane film 23" disposed on the
twill layer 22", a waterproof bar 30" disposed on a seam portion of
the polyurethane film 23', another polyurethane film 41" disposed
on the waterproof bar 30", and a lining 40" disposed on the
polyurethane film 41". The waterproof bar 30" is made of a
waterproof adhesive or a hot-melting adhesive. It is very expensive
to use the polyurethane film, the waterproof adhesive or the
hot-melting adhesive. If the waterproof bar 30" is made of the
hot-melting adhesive, the hot-melting adhesive is useless unless a
certain pre-heating temperature is reached. Water will leak from a
plurality of seaming apertures formed on the polyurethane film 23".
Water will leak from any seam portion of the second conventional
waterproof shoe 20" while a waterproof treatment is improper.
SUMMARY OF THE INVENTION
[0004] An object of the present invention is to provide a
waterproof shoe which has a rubber layer to prevent water from
entering an inner interior of the waterproof shoe.
[0005] Another object of the present invention is to provide a
waterproof shoe which has a waterproof plastics layer to prevent
water from entering an inner interior of the waterproof shoe.
[0006] Accordingly, a waterproof shoe comprises an outer skin, a
lining, and a waterproof layer disposed between the outer skin and
the lining.
[0007] In accordance with a first preferred embodiment of the
present invention, a waterproof shoe comprises an outer skin, a
twill layer, a rubber layer, and a lining. The twill layer is
disposed on the outer skin. The rubber layer is disposed on the
twill layer. The lining is disposed on the rubber layer.
[0008] In accordance with a second preferred embodiment of the
present invention, a waterproof shoe comprises an outer skin, a
plastics layer, and a lining. The plastics layer is disposed
between the outer skin and the lining.

of a first preferred embodiment in accordance with the present
invention;
[0015] FIG. 4A is a partially elevational assembly view of an outer

preferred embodiment in accordance with the present invention;
[0016] FIG. 5 is a perspective view of a waterproof shoe of a
second preferred embodiment in accordance with the present
invention; and
[0017] FIG. 5A is a partially perspective assembly view of an outer
skin, a waterproof plastics layer and a lining of a second
preferred embodiment in accordance with the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0018] Referring to FIGS. 4 and 4A, a first waterproof shoe 20
comprises an outer skin 21, a twill layer 22, a rubber layer 50,
and a lining 40.
[0019] The twill layer 22 is disposed on the outer skin 21.
[0020] The rubber layer 50 is disposed on the twill layer 22.
[0021] The lining 40 is disposed on the rubber layer 50.
[0022] Referring to FIGS. 5 and 5A, a second waterproof shoe 2a
comprises an outer skin 20a, a plastics layer 60a, and a lining
40a.
[0023] The plastics layer 60a is disposed between the outer skin
20a and the lining 40a.
[0024] Since the present invention does not need seam portions,
water cannot enter an inner interior of the waterproof shoe of the
present invention. However, water will leak from seaming apertures
formed on the polyurethane film of the conventional waterproof shoe
and water will leak from any seam portion of the conventional
waterproof shoe while a waterproof treatment is improper. The
rubber layer and the plastics layer of the present invention are
pre-formed into a shoe shape, so water leakage test will be
performed to guarantee a waterproof quality of the present
invention. The present invention need not use any waterproof
adhesive nor any hot-melting adhesive in order to lower a
manufacture cost. The present invention need not use polyurethane
film in order to provide a soft lining.
[0025] The invention is not limited to the above embodiment but
various modification thereof may be made. Further, various changes
in form and detail may be made without departing from the scope of
the invention.
