Claims
1-7. (canceled)
8. A writing instrument, comprising: a barrel; said barrel having
bladders built in to said barrel; and a pumping mechanism for
pumping air into said bladders, said pumping mechanism including an
airway passage and a one way air valve for air to enter from said
pumping mechanism into said bladders.
9. The writing instrument of claim 8 wherein said pumping mechanism
includes an integrated clicker and a pump handle.
10. The writing instrument of claim 8 wherein said pumping
mechanism includes a pump handle that is separate from a clicker
for said writing instrument.
11. The writing instrument of claim 8 wherein said bladders are
formed of rubber-like material.
12. The writing instrument of claim 8 wherein said bladders are
formed of rubber material.
13. The writing instrument of claim 8 further comprising a release
mechanism located on the side of the writing instrument for
releasing excess air.
14. The writing instrument of claim 13 wherein said release
mechanism includes a clip that when pressed and held into place
against the side of the writing instrument presses a release button
at the side of the writing instrument to release said excess air
from said bladders.
15. The writing instrument of claim 8 wherein said bladders can be
manually pumped by a user pressing and releasing said bladders to
inflate said bladders with air.
16. The writing instrument of claim 11 wherein said bladders can be
manually pumped by a user pressing and releasing said bladders to
inflate said bladders with air.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a writing instrument with
inflatable bladders built into the barrel of the writing instrument
to facilitate different sizes for a better and more comfortable
gripping by a user. In particular, the present invention relates to
a writing instrument where the built in bladders are inflated by
pumping air into them. The writing instrument further includes a
release mechanism for releasing excess air in the bladders.
[0003] 2. The Prior Art
[0004] U.S. Patent Publication 2004/0136769 to Ferra relates to a
cushioning element with a deformable bladder having a filling
chamber of a particulate matter that is mounted on an article. The
bladder is not however pumped with air.
[0005] U.S. Pat. No. 4,035,089 to Schwartz et al. relates a grip
whose size is varied with an expander element carried by sleeve
upon rotation of the sleeve. The bladder is mechanically increased
rather than by pumping air.
SUMMARY OF THE INVENTION
[0006] It is therefore a principle object of the invention to
provide a writing instrument having bladders built into the barrel
of a writing instrument which can be inflated by pumping air. In
one embodiment the bladders can be inflated by clicking do on top
of the writing instrument to inflate the bladders while placing
one's finger over the top of the writing instrument. In another
embodiment the bladders can be pumped themselves. A release button
on the side of the writing instrument can be pressed to release
excess air from the bladder.
[0007] Other objects of the invention will become clear and
apparent from the foregoing description and accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a sectional view of the invention showing the
clicker and pump handle;
[0009] FIG. 2 is a sectional view along lines A-A of FIG. 1 showing
the compression spring;
[0010] FIG. 3A is another sectional view of the invention showing
an air release button;
[0011] FIG. 3B is a top view of FIG. 3A;
[0012] FIG. 4A is a sectional view along lines B-B of FIG. 3A
showing the one way valve;
[0013] FIG. 4B is a view along lines C-C of FIG. 4A showing the air
release mechanism;
[0014] FIG. 5A illustrates another feature of the invention in
which release mechanism releases excess air from the bladders and
shows the bladders in their un-inflated state;
[0015] FIG. 5B shows the invention of FIG. 5A with the bladders in
their inflated state; and
[0016] FIG. 6A-D illustrates several different embodiments of
bladders in their inflated states.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring now to the drawings of FIGS. 1-6D, FIG. 1 shows
the present invention which is comprised of a clicker and a pump
handle 11, a compression spring 12, air way passages, a one way air
valve 18, and air expandable bladders 16 are preferably formed of
either rubber-like material or rubber material that are built into
the barrel of the writing instrument.
[0018] The clicker and pump handle apparatus 11 can be pressed down
by a user's finger to compress the spring 12 and pump air from the
air way into the writing instrument's bladders 16 through the one
way air valve 18 shown in FIGS. 4A and 4B. Thereby inflating the
air expandable bladders 16 so that the bladders go from the
un-inflated state in FIG. 5A to the inflated state in FIG. 5B.
[0019] In an alternate embodiment of the invention (not shown) the
pump handle is separate from the clicker for the writing instrument
10 but otherwise operates in the same fashion described FIG. 1.
Alternatively both of these embodiments can have there bladders 16
filled with air by pressing the bladders 16 and pumping them fill
with air.
[0020] FIG. 3. shows a release mechanism 20 located on the side of
the writing instrument 10 which when pressed and held releases air
from the bladders 16 until the desired amount of air is retained
within the bladders. 16.
[0021] The bladders 16 can have various confirmations as shown in
FIGS. 6A-D showing these different bladder embodiments in their
inflated states.
[0022] I do not limit myself to any particular details of
construction set forth in the specification and illustrated in the
accompanying drawings, as the same refers to and sets forth only
certain embodiments of the invention, and it is observed that the
same may be modified without departing from the spirit and scope of
the claimed invention.
