BACKGROUND OF THr INVENTION
Field of the Invention The present invention relates to a nail clipper, and more particularly, the pre::>ent~ inventic~n relates to a nail clipper which effectively prevents a nail clipping from scattering and allows a portion of a nail- to be neatly and perfectly severed from the nail without being partially held stuck to the nail.
Description of the Related Art Generally, a nail clipper designates a device for severing a fingernail or t:oena:il. Referring to FIG. l, there is shown a perspective view illu:_>trat:ing a construction of the conventional nail clipper.
The nail clipper I includes an upper arm member 2 and a lower arm member 3 . Front= ends of the upper and lower arm members
2 and 3 are formed with an upper j aw and a lower j aw, respectively.
Free ends of the uppe.r_ and lower j aws are formed with an upper cutting edge 9 and a :Lower cutting edge 9a, respectively.
The upper and lower arm members 2 and 3 are made of material having desired elasticity and are springly coupled with each other at their rear ends. A pair of holes are defined at portions which are adjacent to t:he front ends of the upper and lower arm members 2 and 3, respectively. A shaft member 5 is rotatably fitted through the pa=it of holes from bottom to top.
_i-An outward flange portion is formed at a lower end of the shaft member 5. The outward flange portion is maintained in a state wherein it is brc>ught into contact with a lower surface of the lower arm member 3. An actuating handle 4 is seated on an upper surface of the upper arm member 2. A front end of the actuating handle 4 is rc~tatably fastened to the shaft member by a retainer pin 6.
The front end of the actuating handle 4 is formed with a fulcrumprotrusion 7. =,here fore, in a state wherein the fulcrum protrusion 7 is brought into contact with the upper surface of the upper arm member ~.' by manipulation of the actuating handle 4, if the actuating handle 4 is depressed, as the upper arm member 2 is moved toward the lower arm merrcber 3, a portion of a nail which is placed between the upper cutting edge 9 and the lower cutting edge '~a, is severed.
However, in the conventional nail clipper 1 constructed as mentioned above, a problem is caused in that, as the upper arm member 2 is moved toward the lower arm member 3 to compress the portion of the nail, natural curvature of the portion of the nail is flat:tenec~, and thereby, when the portion of the nail is severed, a nail clipping scatters from the nail clipper 1 in an unpredictable trajectory by force generated by the upper and lower cutting edge: 9 and 9a for compressing the portion of the nail and force generated by a snap-back phenomenon of the nail clipping to i'~s natural shape.
To cope with the foregoing problem associated with the conventional. nail clipper l, a separate receptacle 8 as shown in FIGS. 1 and 2 is used in such a manner that the nail clipper 1 is fitted into the receptacle 8. In this way, the nail clipping which is severed by t=:he upper and lower cutting edges 9 and 9a, can be received into the receptacle 8.
However, since the receptacle 8 is fitted around the nail clipper 1 in such a manner that a front end of the receptacle 8 sufficiently covers b«th front side end surfaces of the upper and lower arm members 2 and 3 so as to prevent the severed nail clipping from scattering sideward of the nail clipper 1, the nail which is placed k>etween the upper and lower cutting edges 9 and 9a cannot be seer., whereby it is impossible to properly secure a field of view through the nail clipper 1.
To solve this draw~~ack, as shown in FIGs. 1 and 2, a pair of grooves 8' are defined at the front end of the receptacle 8 so that they are opposite to each other. However, these grooves 8' are not enough to properly secure the field of view through the nail clipper 1, an~~, rather, there is possibility of the severed nail clipping t:o :scatter out of the nail clipper 1 through the grooves 8' .
Hence, when the nai_L clipper 1 having the receptacle 8 is employed by a user, in order to enable the user to clip the nail while directly ;riewing the nail portion to be severed, the receptacle 8 is used in such a manner that it is put from the upper ar_d lower cut:t=ing edges 9 and 9a by a predetermined distance as shown in F==G. 2. In this case, the likelihood of the severed nail cli~,ping to scat-ter out of the nail clipper 1 through side openings t' each of which is defined between the
Free ends of the uppe.r_ and lower j aws are formed with an upper cutting edge 9 and a :Lower cutting edge 9a, respectively.
The upper and lower arm members 2 and 3 are made of material having desired elasticity and are springly coupled with each other at their rear ends. A pair of holes are defined at portions which are adjacent to t:he front ends of the upper and lower arm members 2 and 3, respectively. A shaft member 5 is rotatably fitted through the pa=it of holes from bottom to top.
_i-An outward flange portion is formed at a lower end of the shaft member 5. The outward flange portion is maintained in a state wherein it is brc>ught into contact with a lower surface of the lower arm member 3. An actuating handle 4 is seated on an upper surface of the upper arm member 2. A front end of the actuating handle 4 is rc~tatably fastened to the shaft member by a retainer pin 6.
The front end of the actuating handle 4 is formed with a fulcrumprotrusion 7. =,here fore, in a state wherein the fulcrum protrusion 7 is brought into contact with the upper surface of the upper arm member ~.' by manipulation of the actuating handle 4, if the actuating handle 4 is depressed, as the upper arm member 2 is moved toward the lower arm merrcber 3, a portion of a nail which is placed between the upper cutting edge 9 and the lower cutting edge '~a, is severed.
However, in the conventional nail clipper 1 constructed as mentioned above, a problem is caused in that, as the upper arm member 2 is moved toward the lower arm member 3 to compress the portion of the nail, natural curvature of the portion of the nail is flat:tenec~, and thereby, when the portion of the nail is severed, a nail clipping scatters from the nail clipper 1 in an unpredictable trajectory by force generated by the upper and lower cutting edge: 9 and 9a for compressing the portion of the nail and force generated by a snap-back phenomenon of the nail clipping to i'~s natural shape.
To cope with the foregoing problem associated with the conventional. nail clipper l, a separate receptacle 8 as shown in FIGS. 1 and 2 is used in such a manner that the nail clipper 1 is fitted into the receptacle 8. In this way, the nail clipping which is severed by t=:he upper and lower cutting edges 9 and 9a, can be received into the receptacle 8.
However, since the receptacle 8 is fitted around the nail clipper 1 in such a manner that a front end of the receptacle 8 sufficiently covers b«th front side end surfaces of the upper and lower arm members 2 and 3 so as to prevent the severed nail clipping from scattering sideward of the nail clipper 1, the nail which is placed k>etween the upper and lower cutting edges 9 and 9a cannot be seer., whereby it is impossible to properly secure a field of view through the nail clipper 1.
To solve this draw~~ack, as shown in FIGs. 1 and 2, a pair of grooves 8' are defined at the front end of the receptacle 8 so that they are opposite to each other. However, these grooves 8' are not enough to properly secure the field of view through the nail clipper 1, an~~, rather, there is possibility of the severed nail clipping t:o :scatter out of the nail clipper 1 through the grooves 8' .
Hence, when the nai_L clipper 1 having the receptacle 8 is employed by a user, in order to enable the user to clip the nail while directly ;riewing the nail portion to be severed, the receptacle 8 is used in such a manner that it is put from the upper ar_d lower cut:t=ing edges 9 and 9a by a predetermined distance as shown in F==G. 2. In this case, the likelihood of the severed nail cli~,ping to scat-ter out of the nail clipper 1 through side openings t' each of which is defined between the
-3-upper and lower cutting edges 9 and 9a and the front end of the receptacle 8, is increased.
Further, in the conventional nail clipper 1, because specific means for severing, ir.. a lengthwise direction of the nail, both ends of the nail portion which is already severed in a widthwise direction of the nail, is not provided, there is possibility of the severed nail p:~rt:ion to be partially held stuck to the nail, and, in the com:~se of removing the nail portion from the nail, the nail can be damaged.
Moreover, when clipping the nail while moving the nail clipper l, the nail. port;_Lon which ~_s severed and partially held stuck to the nail, can adversely affect the continuous severing operation of the nai=_. clipper l, whereby it is difficult to neatly sever the nail. Also, due to the fact that the already severed nail portion can be severed again, after clipping, an outline of the nail can be roughened, and, thereby, it may be necessary to file the nail smooth.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and a primary object of the present invention is to provide a nail clipper which effectively prevents a nail clipping from scattering.

DETAILED DESCRIFTTc~N OF PREFERRED EMBODIMENTS
Reference will nc>w be made in greater detail to a preferred embodiment of the inveni_ien, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.
FIG. 3 is a pers.~ec;tive view illustrating a construction of a nail clipper having side cutting edges, in accordance with an embodiment of the present invention; and FIG. 4 is a partially cross-sectioned side view illustrating a state wherein a receptacle is removed f rom the nail clipper having side cutting _g_ edges according to the present invention.
A nail clipper 10 according to the present invention includes an upper arm member 12, a lower arm member 14, an actuating handle 16 and a shaft member 18. The upper arm member 12 is formed at a front end t=hereof with an upper cutting edge 26.
The upper arm member 12 has a pair of upper side cutting edges 30 which are formed in such a manner that they extend by a predetermined length from both ends of the upper cutting edge 26 along both widthwise end surfaces, respectively, of the upper arm member 12. The locaer arm member 14 is springly coupled at a rear end thereof to a rear end of the upper arm member 12.
The lower arm member :L4 is formed at a front end thereof with a lower cutting edge ~'_8. The lower arm member 14 has a pair of lower side cutting edges 32 which are formed in such a manner that they extend by the predetermined length from both ends of the lower- cutting eclc~e 28 along both widthwise end surfaces, respectively, of the 1_ower arm member 14.
The shaft member 18 is rotatably fitted through portions of the upper and lower. arm members 12 and 14, which portions are adjacent to the fz:ont. ends of the upper and lower arm members 12 and 14, respectivE:ly. The actuating handle 16 is rotatably fastened to the shaft member 18 by a retainer pin 20 i_n such a manner that. it is seat:.ed on the upper arm member 12 . The actuating handle 16 performs a f='unct:ion of depressing the upper arm member 12 toward the lower arm member 14. To this end, the actuating handle 16 is formed with a fulcrum protrusion 22. In a state wherein the fulcrum protrusion 22 is brought into contact with an upper surface of the upper arm member 12 by manipulation of the actuating handle 1 E~, if the actuating handle 16 is depressed, as the upper arm member 12 is moved toward the lower arm member 14, it is possible to sever a portion of a nail using the upper cutting edge 26, the lower cutting edge 28, the pair of upper side cutting edges 30 and the pair of lower side cutting edges 32.
Due to the fact th<~t the upper and lower side cutting edges 30 and 32 are formed, the severed nail portion is prevented from scattering out of the nail clipper 10. Also, since the nail portion is sever°ecL not only in a widthwise direction of the nail but also in <~ Lengthwise direction of the nail, it is possible to prevE:nt the severed nail portion from being partially held stuck t:o t:he nail (see FIG. 7) . The upper cutting edge 26 and t:he pair of upper side cutting edges 30 cooperatively define subst:antially a "~"-shaped cross-section, and the lower cutting edge 28 and the pair of lower side cutting edges 32 cooperatively define substantially a "~"-shaped cross-section, whereby the nail portion can be neatly and perfectly severed from the nail.
According to anc>ther embodiment of the present invention, instead of t:he pair of upper side cutting edges 30 and the pair of lower side cutting edges 32, a pair of scatter preventing upper barriers and a p~iir of scatter preventing lower barriers can be formed along bot:h widthwise end surfaces of the upper and lower arm members, respectively, in such a way as to each extend by a preset length. Each of the scatter preventing upper and lower barriers has a height which is lower than that of each of the upper and lower cutting edges 26 and 28.
Hence, when the u~>per arm member 12 is depressed by the actuating handle 16 to be set in a nail shearing engagement with the lower arm member 14, the upper and lower barriers prevent a nail clipping, that is, the severed nail portion, from scattering, and at the same time, since a predetermined gap is defined between the upper and lower barriers, nail severing operations of the upper and lower cutting edges 26 and 28 are not deteriorated by the upper and lower barriers .
Further, as clea.r_ly shown in FIG. 3, a receptacle 24 for accommodating nail cli~:~pings can be fitted around the nail cl ipper in such a manner that its front. end covers end portions of the upper and lower side cutting edges 30 and 32. In this case, the receptacle 24 compl~=menu the function of the side cutting edges 30 and 32 to prevent. the severed nail portion from scattering out of the nail clipper :LO and holds severed nail portions until such time as the user desires to dispose of them.
Referring to FIG. 5, there is shown a side view illustrating a construction of a nai:1 clipper having side cutting edges and side wall parts, in ai:cordance with another embodiment of the present invention.
In this embodiment of the present invention, a pair of upper side wall parts 34 are integrally connected to rear ends of the pair of upper side cutting edges 30, respectively, in such a manner that they extend by a preselected length along both widthwise end slarfac:es, respectively, of the upper arm member 12. Also, a paia: of 7_ower side wall parts 36 are integrally connected to rear end~~ o.f the pair of lower side cutting edges 32, respectively, in such a manner that they extend by the preselected length along both widthwise end surfaces;
respectively, of the lower arm member 14. Each of the upper and lower side wall parts 34 and 36 has a height which is lower than that of each of upper and lower side cutting edges 30 and 32.
Referring to FIGs . 6a through 6d, there are shown schematic plan views illustratincr a diversity of contours of upper and lower cutting edges of the nail clipper according to the present invention.
The upper and lower cutting edges 26 and 28 can have a diversity of contours _..ncluding a straight contour 38, a concave contour 40, a convex c<:>ntour 42, a round contour 44 or the like, depending upon the use an~~ the funct=ionality of the nail clipper 10.
As a result, by the nail clipper according to the present invention constructed asmentionedabove,advantagesareprovided in that, since side wal.7_ parts and/or side cutting edges are formed along both widthw~_se end surfaces of arm members, a nail clipping is prevented from scattering, whereby the nail clipping is effectively maintained inside the nail clipper, and a portion of a nail is neatly anc, perfectly severed from the nail.
In the drawings and specification, there have been disclosed typical preferred embodiments of the invention and, although specific terms are err~ployed, they are used in a generic and descriptive sense only <~nd not for purposes of limitation, the scope of the invention being set forth in the following claims.
According to still another aspect of the present invention, the nail clipper further comprises a receptacle for accommodating nail clippings, the weceptacle being fitted around the nail clipper in such a manner that its front end covers end portions of the upper and lower aide cutting edges.
According to yet still another aspect of the present invention, the upper and lower cutting edges have a straight, concave, convex or round configuration.
By the :features of t:he present invention, due to the fact that side wall parts anc~!or side cutting edges are formed along both widthwise end sl:lrfaces of arm members, a nail clipping is prevented from scat;t=ering, whereby the nail clipping is effectively maintained inside the nail clipper, and a portion of a nail is neatly and perfectly severed from the nail.

DETAILED DESCRIFTTc~N OF PREFERRED EMBODIMENTS
Reference will nc>w be made in greater detail to a preferred embodiment of the inveni_ien, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.
FIG. 3 is a pers.~ec;tive view illustrating a construction of a nail clipper having side cutting edges, in accordance with an embodiment of the present invention; and FIG. 4 is a partially cross-sectioned side view illustrating a state wherein a receptacle is removed f rom the nail clipper having side cutting _g_ edges according to the present invention.
A nail clipper 10 according to the present invention includes an upper arm member 12, a lower arm member 14, an actuating handle 16 and a shaft member 18. The upper arm member 12 is formed at a front end t=hereof with an upper cutting edge 26.
The upper arm member 12 has a pair of upper side cutting edges 30 which are formed in such a manner that they extend by a predetermined length from both ends of the upper cutting edge 26 along both widthwise end surfaces, respectively, of the upper arm member 12. The locaer arm member 14 is springly coupled at a rear end thereof to a rear end of the upper arm member 12.
The lower arm member :L4 is formed at a front end thereof with a lower cutting edge ~'_8. The lower arm member 14 has a pair of lower side cutting edges 32 which are formed in such a manner that they extend by the predetermined length from both ends of the lower- cutting eclc~e 28 along both widthwise end surfaces, respectively, of the 1_ower arm member 14.
The shaft member 18 is rotatably fitted through portions of the upper and lower. arm members 12 and 14, which portions are adjacent to the fz:ont. ends of the upper and lower arm members 12 and 14, respectivE:ly. The actuating handle 16 is rotatably fastened to the shaft member 18 by a retainer pin 20 i_n such a manner that. it is seat:.ed on the upper arm member 12 . The actuating handle 16 performs a f='unct:ion of depressing the upper arm member 12 toward the lower arm member 14. To this end, the actuating handle 16 is formed with a fulcrum protrusion 22. In a state wherein the fulcrum protrusion 22 is brought into contact with an upper surface of the upper arm member 12 by manipulation of the actuating handle 1 E~, if the actuating handle 16 is depressed, as the upper arm member 12 is moved toward the lower arm member 14, it is possible to sever a portion of a nail using the upper cutting edge 26, the lower cutting edge 28, the pair of upper side cutting edges 30 and the pair of lower side cutting edges 32.
Due to the fact th<~t the upper and lower side cutting edges 30 and 32 are formed, the severed nail portion is prevented from scattering out of the nail clipper 10. Also, since the nail portion is sever°ecL not only in a widthwise direction of the nail but also in <~ Lengthwise direction of the nail, it is possible to prevE:nt the severed nail portion from being partially held stuck t:o t:he nail (see FIG. 7) . The upper cutting edge 26 and t:he pair of upper side cutting edges 30 cooperatively define subst:antially a "~"-shaped cross-section, and the lower cutting edge 28 and the pair of lower side cutting edges 32 cooperatively define substantially a "~"-shaped cross-section, whereby the nail portion can be neatly and perfectly severed from the nail.
According to anc>ther embodiment of the present invention, instead of t:he pair of upper side cutting edges 30 and the pair of lower side cutting edges 32, a pair of scatter preventing upper barriers and a p~iir of scatter preventing lower barriers can be formed along bot:h widthwise end surfaces of the upper and lower arm members, respectively, in such a way as to each extend by a preset length. Each of the scatter preventing upper and lower barriers has a height which is lower than that of each of the upper and lower cutting edges 26 and 28.
Hence, when the u~>per arm member 12 is depressed by the actuating handle 16 to be set in a nail shearing engagement with the lower arm member 14, the upper and lower barriers prevent a nail clipping, that is, the severed nail portion, from scattering, and at the same time, since a predetermined gap is defined between the upper and lower barriers, nail severing operations of the upper and lower cutting edges 26 and 28 are not deteriorated by the upper and lower barriers .
Further, as clea.r_ly shown in FIG. 3, a receptacle 24 for accommodating nail cli~:~pings can be fitted around the nail cl ipper in such a manner that its front. end covers end portions of the upper and lower side cutting edges 30 and 32. In this case, the receptacle 24 compl~=menu the function of the side cutting edges 30 and 32 to prevent. the severed nail portion from scattering out of the nail clipper :LO and holds severed nail portions until such time as the user desires to dispose of them.
Referring to FIG. 5, there is shown a side view illustrating a construction of a nai:1 clipper having side cutting edges and side wall parts, in ai:cordance with another embodiment of the present invention.
In this embodiment of the present invention, a pair of upper side wall parts 34 are integrally connected to rear ends of the pair of upper side cutting edges 30, respectively, in such a manner that they extend by a preselected length along both widthwise end slarfac:es, respectively, of the upper arm member 12. Also, a paia: of 7_ower side wall parts 36 are integrally connected to rear end~~ o.f the pair of lower side cutting edges 32, respectively, in such a manner that they extend by the preselected length along both widthwise end surfaces;
respectively, of the lower arm member 14. Each of the upper and lower side wall parts 34 and 36 has a height which is lower than that of each of upper and lower side cutting edges 30 and 32.
Referring to FIGs . 6a through 6d, there are shown schematic plan views illustratincr a diversity of contours of upper and lower cutting edges of the nail clipper according to the present invention.
The upper and lower cutting edges 26 and 28 can have a diversity of contours _..ncluding a straight contour 38, a concave contour 40, a convex c<:>ntour 42, a round contour 44 or the like, depending upon the use an~~ the funct=ionality of the nail clipper 10.
As a result, by the nail clipper according to the present invention constructed asmentionedabove,advantagesareprovided in that, since side wal.7_ parts and/or side cutting edges are formed along both widthw~_se end surfaces of arm members, a nail clipping is prevented from scattering, whereby the nail clipping is effectively maintained inside the nail clipper, and a portion of a nail is neatly anc, perfectly severed from the nail.
In the drawings and specification, there have been disclosed typical preferred embodiments of the invention and, although specific terms are err~ployed, they are used in a generic and descriptive sense only <~nd not for purposes of limitation, the scope of the invention being set forth in the following claims.
