Description
BACKGROUND OF THE INVENTION
[0001] This invention is a foot health care device that allows
people to remove foot callus hand-free simply by rubbing the foot
against the device while taking a shower. It adds the function of
the rasp to a strainer.
[0002] Foot callus can accumulate and become very thick if it is
not taken care of properly. The accumulated callus on feet causes
the rough skin that can be easily chapped. Walking with a chapped
feet could cause a lot of pain while walking. The worst it could
cause the foot related disease or disorders.
[0003] I always want to remove the accumulated foot callus when I
take a shower because it is getting very soft after soaking in the
water, and it is much easier to be got rid of at this time. However
I can not find a convenient tool. So I would rub my foot against
the surface of the strainer back and forth a few times. It works a
little bit but not that good. Sometimes I would find something
rough to file the foot callus but I have to bend my leg to raise
the foot (this can be extremely difficult for those aged, disabled,
pregnant, overweighed and arthritic people). Most often I have to
lean against the wall using one hand to balance my body. After a
while my leg would feel sore and tired and I have to stop to take a
rest and change the gesture. It is important to point out it is not
safe as well. People would easily fell down because of the losing
of the balance while leaning against the wall of the shower stall
standing with only one foot on the wet floor, which can cause bone
breaking.
[0004] I have tried to find an easy-to-use callus remover in the
market. Unfortunately there are not many products available. Most
of them require using hands and bending the leg or bending over,
some of them using brushes or cloth and they are not working very
efficiently and effectively for removing the foot callus. So I
think why couldn't I invent a foot callus remover that not only
allows the water going through but also can remove foot callus hand
free and safe without bending the leg and raising the foot? Thus
the idea was born.
BRIEF SUMMERY OF THE INVENTION
[0005] This invention is a foot health care device with strainer
for removing foot callus hand-free while people are taking shower.
It adds the function of a rasp to a strainer for removing foot
callus.
[0006] The invented device has the following features and
advantages:
[0007] (a) It comprises four interconnected parts: a cylinder
bottom, strips of ridges, supporting frames, and an outside flat
rim.
[0008] The bottom part is a cylinder with twenty-one draining holes
that can be plugged in a regular strainer passageway to allow water
going through. On the surface of the upper portion of the device
are arc-like strips of ridges functioned as rasp for removing foot
callus. The frames under the strips provide strength and support to
the device. The intersecting of the arc-like strips and frames
forms twenty-one holes that are connected with the bottom portion
and make it a dome-shaped design. This kind of design allows almost
any part of the foot to be cleaned. Around the dome-shaped upper
portion is a scale-like flat rim functioned as a fine rasp that
allows the foot skin to be fine-tuned.
[0009] (b) It is very convenient and easy to remove the foot callus
when it is soaked by the water and becomes soft. People can remove
the foot callus hand free effectively and efficiently simply by
rubbing the foot against the dome-like ridged area of the device
while taking a shower. It saves the time, too.
[0010] (c) It is safe to use the device. You can remove the foot
callus without the help of the hands and bending the leg or bending
over while taking a shower, so it is safe and your leg would no
longer feel sore and tired. You could use your two hands to lean
against the wall when necessary. This is extremely beneficial for
those aged, pregnant, disabled, overweighed and arthritic
people.
[0011] (d) It is easy to install. The size of the device is the
same as a regular strainer. It simply takes place of the
traditional strainer without taking more space. It is so easy to
install that it takes only a few minutes to replace the old
strainer with the new device.
[0012] (e) It cleans itself. Since the device is installed in the
current strainer passageway the removed foot callus will be rushed
into the draining holes along with the shower water. No cleaning is
needed.
[0013] (f) The device can be made using the same kind plastic
material that makes a traditional strainer. The process of making
it is simple and the cost is low.
[0014] In general the device is safe, practical, and easy to use.
It saves time and money and everyone would need it. It is good for
foot health.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING
[0015] FIG. 1 is a plane view.
[0016] FIG. 2 is a section view.
[0017] FIG. 3 is a side view.
[0018] FIG. 4 is a bottom view.
[0019] FIG. 5 is a front page view.
DETAILED DESCRIPTION OF THE INVENTION
[0020] This device has a dome-like appearance. It looks like a hat
with a brim. Its diameter is only 41/4 inches (10.795 cm) the same
size as a regular strainer, and the outside rim is 3/4 inch (2 cm)
wide.
[0021] It has four portions: a flat rim 1, supporting frames 2,
four strips of ridges 3, and a cylinder bottom 4.
[0022] Referring to FIG. 4 the bottom portion is a cylinder 4 that
is 8 mm high. It has twenty-one draining holes 5 that allow the
shower water going through. It is designed to plug in a regular
strainer passageway in a shower stall.
[0023] Referring to FIG. 1, 2 and 3 the dome-like upper portion
looks like a hat. It is composed of four arc-like strips of ridges
3 with different length. On the surface of each said strips are
four ridges 3 that function as a rasp for removing foot callus. The
supporting frames 2 intersect and connect below the said strips of
ridges 3 to provide extra strength and support to the ridges 3
area. The intersection of the four strips of ridges 3 and
supporting frame 2 forms twenty-one draining holes 5 that connect
with the cylinder bottom 4. The arc-like strips of ridges 3 and
supporting frames 2 make the upper portion of the device a
dome-shaped design. This design allows the foot to be easily
cleaned without tilting it too much.
[0024] The outside scale-like flat rim 1 with 3/4 inches (2 cm) in
width is around the dome-shaped upper portion. The scale-like
little ridged design at top of the rim 1 functions as a fine rasp
to allow the foot skin to be fine-tuned.
[0025] The device can use the same kind of material that makes the
traditional strainer. The process of making it is simple and cost
is low. Its color can be white or any color that matches the color
of the ground of the shower stall.
[0026] There are a few considerations for the design.
[0027] (a) The size is the same as that of a traditional strainer,
which makes it easy to replace the traditional strainer with the
new device.
[0028] (b) It is safe to use. Since it is dome-shaped design it is
not safe if the size is too big. The small size of this kind of
design will not cause the people to fall in case people step on
it.
[0029] (c) The combination of both the dome-shaped ridged surface
and scale-like flat rim area allows effectively and efficiently
removing callus under the foot or side of the foot. People would
have a feeling of massage when rubbing foot against the device.
[0030] (d) The usage of the device is easy, quick and comfortable
and everyone is able to use it. People can remove the foot callus
or massage the foot simply by stepping one foot on top of the
device and rubbing the foot against it back and forth, or moving
the foot around the device.
[0031] This invention has the following advanced features compared
to other callus removers:
[0032] (a) Some of the current callus removers need to be installed
on the wall or the ground of the shower stall. It need extra space
and is hard to be fastened.
[0033] However this invented device is installed in the passageway
of the traditional strainer. So there is no extra space needed and
it is easy to install and fasten it.
[0034] (b) Some of the callus remover requires using a rasp, a
brush or a bath cloth by hand. People need to bent leg and raise
foot in order to remove the foot callus. Sometimes people have to
use one hand to lean against the wall in order to keep the balance
of the body otherwise people may fall. It is not safe especially
for those aged, disabled, pregnant, overweighed and arthritic
people.
[0035] However this invented device is hand free. People can use it
while taking shower using two hands. It is great beneficial and
helpful for the aged, disabled, pregnant, overweighed and arthritic
people.
[0036] (c) This invented device's diameter is 41/4 inch (10.795 cm)
wide. The size is the same as a regular strainer, so it is easy to
replace with the new device.
[0037] (d) Currently most of the callus removers need to be cleaned
after usage.
[0038] This invented device cleans itself automatically. The
removed foot callus is washed away along with running shower water.
So it is clean free.
[0039] (e) Some of the current callus removers require extra
specific time other than shower time to soak the foot in the water
before foot callus can be removed.
[0040] This device allows people to remove foot callus while taking
shower. So it saves time as well.
[0041] (f) Some of the current callus remover is too complicated to
make.
[0042] This device can be made using the same kind of materials as
the traditional strainer. The process of making it is simple and
the cost is low.
