[0001] The present invention relates to a writing implement such as a ballpoint pen, a mechanical
pencil, and a fountain pen. More particularly, the present invention relates to a
writing implement that is suitable to be used by those with handicap in their hand
and/or finger(s).
[0002] Writing implements that are generally used are rodlike. These conventional writing
implements are to be held by three fingers, or the thumb, the index finger, and the
middle finger, when used. However, the conventional writing implement will move above
through the root between the thumb and the index finger when the pen point is pushed
to the paper surface when the implement is used by a user with a weak grip. Therefore,
the conventional writing implement is extremely difficult to use for those with handicap
in their hand and/or finger(s).
[0003] It is an object of the present invention to provide a writing implement that is suitable
to be used by those with handicap in their hand and/or finger(s).
[0004] The above object and others are accomplished by providing a writing implement which
has a grip having a terminal end having a curved surface adapted to contact with the
palm of a user, the grip being formed such that the grip is held with the fingers
and the palm in such a way that the grip is wrapped by the hand, and a pen point extending
from a front end of the grip with a given angle. The grip can optionally have one
or more concave contours adapted to fit the finger(s) of the user, wherein each concave
contour can fit one or more fingers.
[0005] Embodiments of the present invention will now be described with reference to the
accompanying drawings, in which:
FIG. 1A shows a right side view of a writing implement of an embodiment of the present
invention;
FIG. 1B shows a left side view of the writing implement of FIG. 1A;
FIG. 1C shows a front view of the writing implement of FIG. 1A;
FIG. 1D shows a bottom view of the writing implement of FIG. 1A;
FIG. 1E shows a plan view of the writing implement of FIG. 1A;
FIG. 2 shows the writing implement of FIG. 1A as held in a hand;
FIG. 3A shows a right side view of a writing implement of another embodiment of the
present invention;
FIG. 3B shows a left side view of the writing implement of FIG. 3A;
FIG. 3C shows a front view of the writing implement of FIG. 3A;
FIG. 3D shows a rear elevation of the writing implement of FIG. 3A;
FIG. 3E shows a bottom view of the writing implement of FIG. 3A; and
FIG. 3F shows a plan view of the writing implement of FIG. 3A.
[0006] Referring now to FIGS. 1A - 1E, the writing implement of this embodiment has a grip
11 having a curved surface formed such that the grip 11 is held with the fingers and
the palm in such a way that the grip 11 is wrapped by the hand. The grip 11 shows
a pear-like shape in the plan view in FIG. 1E and the bottom view in FIG. 1D. The
grip 11 shows a comb-like shape in the side views in FIGS. 1A and 1B. The grip 11
has an oval shape that extends in the direction from the front end 11a to the terminal
end 11b wherein the grip 11 is formed such that the front end 11a is narrower than
the terminal end 11b.
[0007] The terminal end 11b of the grip 11 has a curved bulbous surface adapted to contact
with the palm. A pen point 12 extends out from a front end 11a of the grip with a
given angle. The pen point 12 can be a pen point of, for example, a ballpoint pen,
a mechanical pencil, and a fountain pen. The grip 11 houses a member 13 to store,
for example, ink (in the case of a ballpoint pen or a fountain pen) or leads (in the
case of mechanical pencil) as indicated by a dashed line in FIG. 1A.
[0008] When the writing implement described above is used, the implement is hold in such
a way that the terminal end 11b contacts with the palm, that the thumb and the index
fingers pinches the front end 11a or an area near it, and that the middle finger,
the ring finger, and the little finger wraps the bottom surface, as shown in FIG.
2. The implement is supported by not only fingers but also the palm when used. Therefore,
in order to make the implement handy for those with handicap in their hand and/or
finger(s), the pen point 12 should form a certain angle with the grip 11.
[0009] The writing implement described above is particularly suitable to be used by those
with handicap in their hand and/or finger(s). The term "handicap" refers to any kind
of problem that spoils dexterity at conventional writing implement. Therefore, the
handicap can be congenital or acquired and the acquired handicap can be temporal or
permanent. For example, those who has an injury to their fingers or those who has
a congenital defect in their fingers can be called "those with handicap in their hand
and/or finger(s)".
[0010] It will be appreciated by those skilled in the art that this implement can be used
by those without one or more fingers because the implement is supported by not only
fingers but also the palm. It will also be appreciated by those skilled in the art
that this implement can be used by those children who do not yet have a strong grip
enough to hold the conventional writing implement.
[0011] The grip 11 can optionally have one or more concave contours 14 adapted to fit the
finger(s) of the user, wherein each concave contour can fit one or more fingers. This
will allow the user to hold the implement even more firmly and stably. FIGS. 1A -
1E show the grip 11 which has 4 concave contours, one adapted to fit the thumb, another
adapted to fit the index finger, a third adapted to fit the middle finger, and the
other adapted to fit both of the ring finger and the little finger. It will be appreciated
by those skilled in the art that depending upon the particular application, the numbers
of concave contours and the numbers of fingers each concave contour is to fit can
be decided. For example, the grip can have only two concave contours adapted to fit
the thumb and the index finger, respectively, or the grip can have five concave contours
adapted to fit all the five fingers, respectively.
[0012] The grip can be colored in different colors such that those who also have bad eyesight
can hold the grip with ease. For example, as shown in FIGS. 3A - 3F, by coloring in
one color a surface of the grip on which the finger will touch the grip when the implement
is used and by coloring in a different color the rest of the surface, those with a
weak grip as well as bad eyesight can hold the grip with ease.
[0013] Thus, the present invention will accomplish the object to provide a writing implement
that is suitable to be used by those with handicap in their hand and/or finger(s).
[0014] The terms and expressions which have been employed are used as terms and expressions
of description and not of limitation, and there is no intention in the use of such
terms and expressions of excluding any equivalent of the features shown and described,
but it is recognized that various modifications are possible within the scope of the
appended claims.
