[0004] Not applicable.
BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates to a callus removal device
which is used to remove calluses formed on parts of the human body,
for example, on the sole of the foot.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0008] Generally, keratosis palmaris et plantaris is defined as any
condition of skin characterized by the excessive development of
calluses on the palms or the soles of the feet. The above-mentioned
condition is different depending on the shape and distribution of
each callus, heredity, affliction time point and accompanying
abnormal symptoms.
[0009] The calluses are caused by keratinization of epidermal
tissues of the skin, and crack due to the changing of the seasons.
Thus, dermis underneath the calluses may be damaged. To avoid
above-mentioned problems, it is necessary to the periodically
remove the calluses before the condition becomes more serious.
[0010] For this, callus removal devices were proposed and have been
used. The conventional callus removal devices for removing the
calluses include abrasive sand panels which have abrasive sand and
are integrally coupled to rotating shafts of motors.
[0011] However, in such a conventional callus removal device, after
a user uses the callus removal device, callus remnants remain on
the abrasive sand. Even if the abrasive sand is disinfected, the
callus remaining abrasive remnants on the sand can rot. When the
user reuses the callus removal device, the rotten callus remnants
remaining on the abrasive sand come into contact with the palms and
soles of the user. Thus, the palms and soles of the user may become
contaminated with bacilli. As such, the conventional callus removal
devices are unsanitary.
[0012] Furthermore, the use of the conventional callus removal
device in public service places may lead to the communication of
diseases. Thus, the United States of America and several countries
in Europe prohibit the use of the conventional callus removal
device in public service places.
[0013] In an effort to overcome the problems experienced with the
conventional callus removal device, the inventor of the present
invention proposed another callus removal device in Korean Utility
Model Registration No. 20-0342744.
[0014] The callus removal device of No. 20-0342744 includes a main
body, which has a handle and a sand cap support part, and a sand
cap, which is provided with abrasive sand and is fitted over the
sand cap support part. Furthermore, a coupling ring is provided
around the circumferential outer surface of the sand cap support
part of the main body, and a coupling groove is formed around the
inner surface of the sidewall of the sand cap, so that the sand cap
is removably fitted over the sand cap support part using the
coupling ring and the coupling groove.
[0015] To use this callus removal device, a user grasps the handle
of the sand body and scrubs calluses off of palms or soles using
the abrasive sand of the sand cap.
[0016] However, in the callus removal device of No. 20-0342744,
there is a problem in which, because the sand cap is forcibly
fitted over the sand cap support part of the main body, it is
difficult to separate the sand cap from the main body. Furthermore,
when the user separates the sand cap from the main body, the user
must hold the entire sand cap using his/her hand. Therefore, if the
sand cap is not removed from the main body after the callus removal
device has been used, when the user separates the sand cap from the
main body after a long period has passed, the hand of the user may
become contaminated with rotten callus remnants that remain on the
abrasive sand.
BRIEF SUMMARY OF THE INVENTION
[0017] Accordingly, the present invention has been made keeping in
mind the above problems occurring in the prior art, and an object
of the present invention is to provide a callus removal device in
which a disposable sand panel for removing calluses can be easily
separated from a main body provided with a handle.
[0018] In order to accomplish the above object, the present
invention provides a callus removal device, including: a main body
having a handle and a protruding part; a disposable sand panel
removably coupled to the protruding part of the main body, with a
plurality of protrusions provided on a surface of the disposable
sand panel to remove calluses; and a separating member disposed
between the disposable sand panel and the main body, the separating
member being coupled at a first end thereof to a lower surface of
the main body and having a second end extending outside the lower
surface of the main body.

[0030] In addition, the following embodiments are only illustrative
examples facilitating understanding of the present invention, and
do not limit the scope and spirit of the present invention.
Therefore, those skilled in the art will appreciate that various
modifications, additions and substitutions based on the technical
spirit of the present invention are possible.
[0031] FIG. 1 is a perspective view of a callus removal device,
according to a first embodiment of the present invention. FIG. 2 is
an exploded perspective view of the callus removal device. FIG. 3
is a sectional view taken along the line A-A' of FIG. 2. FIG. 4 is
a sectional view taken along the line B-B' of FIG. 2. FIG. 5 is a
bottom perspective view of a main body 120 of the callus removal
device. FIG. 6 is a perspective view showing an operation of
separating a disposable sand panel 100 from the main body 120. FIG.
7 is a perspective view showing another main body 120' coupled to a
handle.
[0032] As shown in the drawings, in a callus removal device
according to the first embodiment of the present invention, the
disposable sand panel 100 is removably coupled to the main body 120
provided with a handle 150. In detail, the callus removal device
includes the disposable sand panel 100, which has on a surface
thereof a plurality of protrusions 102 for removing calluses, the
main body 120, which has a protruding part 130, to which the
disposable sand panel 100 is coupled, and a separating member 125,
which is disposed between the disposable sand panel 100 and the
main body 120, and an inside end of which is attached at a
predetermined position to a lower surface of the main body 120, and
an outside end of which extends outside the lower surface of the
main body 120.
[0033] Here, the disposable sand panel 100 has the protrusions 102,
which are made of abrasive sand for removing calluses. The
separating member 125 is attached to the main body 120 before the
disposable sand panel 100 is coupled to the main body 120. In other
words, the separating member 125 is interposed between the
disposable sand panel 100 and the main body 120.
[0034] When a user desires to separate the disposable sand panel
100 from the main body 120, the user pushes the outside end of the
separating member 125. Then, a gap is created between the
disposable sand panel 100 and the main body 120. At this time, the
user inserts his/her fingernail into the gap and applies force to
the disposable sand panel 100 in the direction in which the
disposable sand panel 100 is separated from the main body 120. As
such, the disposable sand panel 100 can be easily separated from
the main body 120.
[0035] That is, the separating member 125 serves to form a gap
between the disposable sand panel 100 and the main body 120, which
are coupled to each other using an adhesive, such that the user can
easily separate the disposable sand panel 100 from the main body
120 using his/her fingernail. The disposable sand panel 100 is
replaced with another disposable sand panel.
[0036] The disposable sand panel 100 includes a ceramic layer 105,
on which the protrusions 102 are provided, and a PVC layer 112 or
paper layer, to which the ceramic layer 105 is coupled. The ceramic
layer 105 may be formed by spraying particles, such as abrasive
sand, onto a bonding agent that is applied to a PVC panel, which
forms the PVC layer 112, or to paper.
[0037] Here, the protrusions 102 are provided on a portion of the
disposable sand panel 100. Each protrusion 102 preferably has a
water droplet shape to prevent the dermis of the user from being
injured when scrubbing calluses. Furthermore, a scrubbing part 110
is formed on a portion of the disposable sand panel 100 other than
the portion on which the protrusions 102 are provided, so that the
scrubbing part 110 along with the protrusions 102 serves to remove
calluses.
[0038] The disposable sand panel 100 is made of plastic such as
PVC. The scrubbing part 110 is formed by applying adhesive paint to
the outer surface of the PVC layer at regular intervals and by
applying abrasive sand to the adhesive paint such that the abrasive
sand is reliably attached to the PVC layer. Thus, "V"-shaped
grooves are formed in the scrubbing part 110 at positions spaced
apart from each other at regular intervals, because abrasive sand
is sprayed onto the adhesive paint, which is applied to the PVC
layer at regular intervals.
[0039] Furthermore, the disposable sand panel 100 has a
longitudinal cross-section and a transverse cross-section which are
convex downwards. Therefore, the disposable sand panel 100 can be
efficiently brought into contact with various parts of the user's
body on which calluses are formed.
[0040] Meanwhile, the protruding part 130, which has a curved
inclined surface 137, and to which the disposable sand panel 100 is
attached, is provided under the lower surface of the main body 120.
The inclined surface 137 of the protruding part 130 contacts and is
coupled to the circumferential inner surface of the disposable sand
panel 100 by the adhesive B.
[0041] Here, the end of the inside separating member 125 is
disposed between the disposable sand panel 100 and the main body
120. When pushing force is applied to the outside end of the
separating member 125, the separating member 125 pushes the
disposable sand panel 100. Thus, the disposable sand panel 100,
which is pushed by the force, is separated from the protruding part
130 of the main body 120.
[0042] The handle 150, which has finger seats 152 on which a user's
fingers are placed, is provided on the upper part of the main body
120. Furthermore, separating grooves 132 are formed on respective
corners of the main body 120, so that the user can easily separate
the disposable sand panel 100 from the main body 120 by inserting
his/her the finger into separating grooves 132 and by pushing the
disposable sand panel 100.
[0043] That is, part of the disposable sand panel 100 is separated
from the protruding part 130 of the main body 120 by pushing the
separating member 125, and, thereafter, the user inserts his/her
finger into the separating grooves 132 and pushes the disposable
sand panel 100. Then, the disposable sand panel 100 is easily
removed from the main body 120.
[0044] A plurality of support protrusions 135, which support the
disposable sand panel 100, is provided under the concave lower
surface of the main body 120. Thus, when the user brings the
disposable sand panel 100 into contact with part of his/her body,
on which calluses are formed, and pushes the main body 120 such
that disposable the sand panel 100 scrubs the calluses with the
disposable sand panel 100, the calluses can be efficiently
removed.
[0045] Although the main body 120 has been illustrated as having
the handle 150 provided with the finger seats 152, the callus
removal device of the present invention may have a main body 120'
provided with a bar type handle that allows the user to easily hold
callus removal device, as shown in FIG. 7.
[0046] Meanwhile, the separating member 125 has a panel shape. A
pushing part 127, which has a cylindrical shape that protrudes
towards the upper part of the main body 120, may be provided on the
outside end of the separating member 125, such that the user can
easily push the separating member 125 downwards. It is preferable
that the pushing part 127 be wider than the panel part coupled
thereto.
[0047] When the user pushes the pushing part 127 downwards using
his/her finger, the separating member 125 is bent downwards and is
brought into contact with the disposable sand panel 100. Then, the
disposable sand panel 100 is pushed by the separating member 125
and is thus separated from the protruding part 130 of the main body
120 based on the separating member 125.
[0048] FIG. 8 is an exploded perspective view of a callus removal
device, according to a second embodiment of the present invention.
FIG. 9 is a perspective view of the assembled removal device
according to the second callus embodiment.
[0049] In the first embodiment, although the disposable sand panel
100 has been illustrated as being attached to the protruding part
130 of the main body 120 with reference to the drawings, the
present invention is not limited to this. As shown in FIG. 8, a
disposable sand panel 100', which has a soft rim 107 that surrounds
the sidewall of the main body 120, is provided on the outer surface
of the lower part of a main body 120. A fastening band 140 is
forcibly fitted over the rim 107 surrounding the sidewall of the
main body 120. In this case, the disposable sand panel 100' can be
coupled to the main body 120 without requiring a separate adhering
process.
[0050] At this time, a separating member 125 is disposed in a cut
142 formed in the fastening band 140. Furthermore, as shown in FIG.
9, the soft rim 107, which is made of synthetic resin and is
provided on the disposable sand panel 100, is interposed between
the main body 120 and the fastening band 140 in a bent state.
[0051] As described above, in a callus removal device of the
present invention, a disposable sand panel provided with a ceramic
layer can be easily separated from a main body merely by pushing a
separating member in one direction. Therefore, the present
invention has an advantage in that a part, which has been used to
remove calluses of a user, can be easily replaced with a new
one.
[0052] Although the preferred embodiments of the present invention
have been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
