DETAILED DESCRIPTION OF THE INVENTION
[0026] As shown in FIGS. 1, 2, and 3, the preferred embodiment of
the waterproof footwear cover of this utility patent includes sole
1, upper 2, vamp 3, and a leg receiving member or boot trunk 4. The
upper 2, vamp 3, and leg receiving member or boot trunk 4 are made
from soft materials, such as waterproof plastic, into one piece.
Sole 1 is made from strong friction bearing materials such as
rubber. The sole 1, upper 2, and vamp 3 form the shoe chamber to
match with the user's shoes. The front end of the sole 1 is shoe
tip 1a. The rear end of sole 1 is the heel 1b. One side of upper 2
attaches to the rear half of sole 1 and the other side attach to
the lower end of the leg receiving member or boot trunk. The upper
end of the leg receiving member or boot trunk 4 is the boot mouth
4a, which allows the user to put their feet into the waterproof
footwear cover. Vamp 3 attaches to the front half of sole 1, and
attaches to upper 2 to form the shoe chamber 7 that has an opening
at the rear end.
[0027] There are several places that elastic or the fastening
member is used in the waterproof footwear cover defined by this
utility patent application. The said elastic or the fastening
member is a long narrow flat belt that is elastic lengthwise. By
placing elastic on the surface of the soft material, especially by
sewing it on the surface of the soft material, the surface of the
soft material can fold up. When sewing together, the elastic should
be stretched out to get sewed to the surface of the soft material.
When the elastic or the fastening member retracts back, it is
attached to several sewing points on the surface of the soft
material. Thus, it will retract with these sewing points. This way
the surface of the soft material will retract too, so the size of
this position will be reduced.
[0028] As shown in FIG. 2, there is a rear elastic or the first
fastening member 9 on the upper 2 near heel 1b. To be specific, the
rear elastic or the first fastening member 9 can be sewed to on the
upper 2 near sole 1. This way, when the users put their feet into
the shoe chamber 7 of the waterproof footwear cover with their
shoes, the rear elastic or the first fastening member 9 will
retract to fold part of the upper 2 of the waterproof footwear
cover. It reduces the size of shoe chamber 7 at this position, so
that the upper 2 of the waterproof footwear cover can be attached
tightly to the upper of the user' shoes. Similarly, there is a
front elastic 8 or the second fastening member on the vamp 3 near
show tip 1a. Specifically, the front elastic or the second
fastening member 8 can be sewed to the vamp 3 near sole 1. Thus the
vamp 3 of the waterproof footwear cover can fold up to reduce the
size of shoe chamber 7 at this position. Thus the vamp 3 of the
waterproof footwear cover can attach to the vamp of the users'
shoes closely. With the joint effort of front and rear elastics 8
and 9, the chamber 7 of the waterproof footwear cover can match
perfectly into the users' shoes. Thus the users' shoes can fit
tightly into the chamber 7 of the waterproof footwear cover, to
prevent the shoes from sliding inside the chamber 7 of the
waterproof footwear cover.
[0029] In a preferred embodiment, since upper 2, vamp 3, and leg
receiving member or boot trunk 4 are made into one piece, when
sealing the one piece upper 2 and vamp 3 onto sole 1, there are
some scraps left. To prevent the scrap from affecting the
appearance of the footwear cover, they can be turned outside upper
2 and vamp 3 to form protection layer 10. Around the mouth of the
protection layer 10 there is a third elastic or the fifth fastening
member 11 to make sure the mouth of the protect layer attaches to
the outside of upper 2 and vamp 3.
[0030] As shown in FIGS. 4, 5, and 6, the second embodiment of the
waterproof footwear cover of this utility patent application
includes sole 1, upper 2, vamp 3, and leg receiving member or boot
trunk 4. This embodiment mostly aims where the users' shoes are
woman's shoes. Similarly, there is a front elastic 8 sewed to the
surface of upper 2 near the shoe tip 1a. And there is a rear
elastic 9 sewed to the surface of the vamp 3 near the heel 1b.
[0031] In the second embodiment, there is flexible elastic or the
third fastening member 12 on the surface of upper 2 near heel 1b.
Both ends of the said elastic 12 are attached to the center of the
upper but its center is not attached to the upper 2. It is possible
to sew both ends of the said elastic 12 to the upper 2 near sole 1,
or even directly to sole 1. Since woman's shoes usually has a high
heel, and the vamp on top of the heel usually leans forward, when
the users' shoes get into the chamber 7 of the waterproof footwear
cover, the center of the elastic or the middle of the third
fastening member 12 can be moved up to the upper of the woman's
high heel shoes so that the heels of the woman's shoes is pressed
on the sole 1, preventing the woman's shoes from moving up and down
inside the chamber 7 of the waterproof footwear cover, and
preventing the woman's shoes from moving back and forth inside the
chamber 7 of the waterproof footwear cover with the help of the
front elastic or the second fastening member 8.
[0032] Because woman's shoes usually have high heels, when they are
directly placed into the chamber of the waterproof footwear cover,
the high heel of the woman's shoes press directly over the sole 1
of the waterproof footwear cover. The whole weight of the user is
concentrated on the small portion of the sole. Thus sole 1 will
quickly wear out. As shown in FIG. 6, in this embodiment, there is
a heel mouth or an aperture 13 on the sole 1 at the position
corresponding to heel's position 1b where woman's high heels 1b'
are. When the user gets the woman's shoes into the chamber 7 of the
waterproof footwear cover, the woman's high heels 1b' can pass
through the heel mouth 13 on the sole 1 of the waterproof footwear
cover to the outside of chamber 7. Thus it can avoid the wearing on
the sole 1 from woman's high heels 1b'. In this embodiment, the
material of sole 1 near heel 1b is made from soft material. The
fifth elastic or the forth fastening member 14 is set around the
said heel mouth 13. Thus heel mouth 13's size matches the size of
the woman's high heel 1b's size, preventing rain water from
entering the chamber 7 of the waterproof footwear cover from the
heel mouth 13. In addition, an aperture 13a can be arranged in the
soft material adjacent to the heel mouth 13 as shown in FIG. 7. The
aperture 13a is used to mount the waterproof footwear cover firmly
around the heel and to prevent the flow of water into chamber
7.
[0033] Besides, since some woman's shoes have a sharp tip, and
since the size of the tips are quite different due to the large
variety of woman's shoes, the sole 1 of the waterproof footwear
cover has to be adaptive to different sizes. In this embodiment,
there is a shoe tip mouth 16 set on the vamp 3 near the tip 1a.
There is elastic rubber cap 15 covering around the said tip mouth
16. The said elastic rubber cap 15 covers the tip mouth 16 to
prevent rain water from entering the chamber 7 of the waterproof
footwear cover through tip mouth 16. When different sizes of shoe
tips are placed into the chamber 7 of the waterproof footwear
cover, the elastic rubber cap 15 can change its size and shape
according to the size and shape of the shoe tip, thus be adaptive
to the tip of different woman's shoes.
[0034] In the preferred embodiment or the second embodiment, there
are fourth elastics or the fifth fastening member 17 sewed around
the mouth of the leg receiving member or boot trunk 4a. This fourth
elastic or the fifth fastening member 17 can retract to reduce the
size of leg receiving member or boot trunk mouth 4a so that leg
receiving member or boot trunk 4 can stick to the leg of the user
tightly. This protects the user's pants from water, and also
prevents leg receiving member or boot trunk 4a from slipping
down.
[0035] In the preferred embodiment or the second embodiment, there
is vertical opening 18 on the said leg receiving member or boot
trunk 4 to help the user getting her feet into the chamber 7 of the
waterproof footwear cover. There are zips or buttons on the
vertical opening 18 for closing the vertical opening 18. It helps
the opening and closing of vertical opening 18, so that the user
can quickly put on or take off the waterproof footwear cover.
[0036] In the preferred embodiment or the second embodiment, there
is a containing bag 19 to pack and store the whole waterproof
footwear cover. This bag can be attached to the said leg receiving
member or boot trunk 4 via string or rope 20 or button. It is also
possible to set a storage hole or bag receiving means 21 on the
inner side or portion of the said leg receiving member or boot
trunk to store the said containing bag through this storage hole or
the bag receiving means 21.
[0037] In the preferred embodiment or the second embodiment, the
said front and rear elastics can be set the same way as the said
elastic, i.e., both ends of the elastics can be set on the sole.
The center of the elastics is not fixed on the upper or vamp so
that the user can wear different sizes and shapes of shoes.
[0038] The present invention has been described in detail, with
reference to the preferred embodiment, in order to enable the
reader to practice the invention without undue experimentation.
However, a person having ordinary skill in the art will readily
recognizes that many of the previous disclosures may be varied or
modified somewhat without departing from the spirit and scope of
the invention.
