BACKGROUND OF THE INVENTION
1. Field of the Invention
The field of invention relates to sporting equipment, and more
particularly pertains to a new and improved racket handle and desiccant
dispenser utilized in association with rackets of various sporting
games to dispense a selective portion of desiccant powder about
selective portions of the handle.
2. Description of the Prior Art
The use of desiccant powder to absorb moisture during the playing
of a sporting event is known in the prior art. Prior art devices
have been relatively complex organizations and have been limited
in the manner in which a desiccant powder may be selectively applied
to various portions of an associated handle. For example, U.S. Pat.
No. 879477 to Kruger sets forth an early application of incorporating
associating apparatus into a tennis racket handle by counter-boring
a tennis racket handle and inserting a weighted medium therewithin
to assist in the swing of the racket by an individual.
U.S. Pat. No. 1045071 to Oldenbusch sets forth a dispenser positioned
within the handle of an associated reflective mirror wherein an
associated valve positioned within an underlying portion of the
handle enables discharge of a toiletry powder therefrom as desired
by an individual.
U.S. Pat. No. 1563352 to Fisher sets forth a tennis racket wherein
the racket handle is provided with a hollow chamber to contain powder
therein wherein a slidably removable disk positioned over a bore
within a side of the handle enables selective removal of powder
in the central chamber. As may be appreciated, this is a rather
rudimentary form of powder dispensing, as opposed to the instant
invention. U.S. Pat. No. 3645008 to Delsack sets forth a means
for discharging a desiccant chamber interiorly of a handle wherein
a central chamber is provided with passageways leading to the handle
surface to accept desiccant powder from the central chamber. The
Delsack patent fails to set forth the selective application of the
associated powder from a plurality of chambers as set forth by the
U.S. Pat. No. 4533139 to Goldin sets forth a tennis racket handle
wherein a cooling medium, such as a pressurized carbon dioxide gas,
is positioned within the handle wherein passageways leading to the
handle minimize perspiration and slippage due to the cooling effect
of the medium positioned within the handle.
As such, it may be appreciated that there is a continuing need
for a new and improved racket handle and desiccant dispenser which
addresses both the problems of effectiveness and ease of use, and
in this respect, the present invention substantially fulfills this
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types
of desiccant dispensers now present in the prior art, the present
invention provides a racket handle and desiccant dispenser wherein
a plurality of manually reciprocatable and spring-biased valves
are axially aligned within a racket handle for selective dispensing
of desiccant powder selectively over discrete portions of a racket
handle. As such, the general purpose of the present invention, which
will be described subsequently in greater detail, is to provide
a new and improved racket handle and desiccant dispenser which has
all the advantages of the prior art desiccant dispensers and none
of the disadvantages.
To attain this, the present invention comprises a racket handle
formed with a centrally aligned chamber. The chamber has formed
therein an upper magazine for securement of desiccant powder therein
with an axially extending rod through the magazine and formed with
a spherical insert to cooperate with a valve seat to be selectively
disengaged from the seat to enable desiccant powder to travel from
the magazine to an underlying first chamber. A second chamber is
axially aligned underlying the first chamber and formed with a guide
bearing axially aligned thereunder to provide support and guidance
for respective valve rods of the first and second chambers extending
outwardly of the handle on either end thereof and provided with
respective valves to enable desiccant powder to be dispensed about
upper and lower surfaces selectively of the racket handle.
My invention resides not in any one of these features per se, but
rather in the particular combination of all of them herein disclosed
and claimed and it is distinguished from the prior art in this particular
combination of all of its structures for the functions specified.
There has thus been outlined, rather broadly, the more important
features of the invention in order that the detailed description
thereof that follows may be better understood, and in order that
the present contribution to the art may be better appreciated. There
are, of course, additional features of the invention that will be
described hereinafter and which will form the subject matter of
the claims appended hereto. Those skilled in the art will appreciate
that the conception, upon which this disclosure is based, may readily
be utilized as a basis for the designing of other structures, methods
and system for carrying out the several purposes of the present
invention. It is important, therefore, that the claims be regarded
as including such equivalent constructions insofar as they do not
depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the
U.S. Patent and Trademark Office and the public generally, and especially
the scientists, engineers and practitioners in the art who are not
familiar with patent or legal terms or phraseology, to determine
quickly from a cursory inspection the nature and essence of the
technical disclosure of the application. The abstract is neither
intended to define the invention of the application, which is measured
by the claims, nor is it intended to be limiting as to the scope
of the invention in any way.
It is therefore an object of the present invention to provide a
new and improved racket handle and desiccant dispenser which has
all the advantages of the prior art desiccant dispensers and none
of the disadvantages.
It is another object of the present invention to provide a new
and improved racket handle and desiccant dispenser which may be
easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new
and improved racket handle and desiccant dispenser which is of a
durable and reliable construction.
An even further object of the present invention is to provide a
new and improved racket handle and desiccant dispenser which is
susceptible of a low cost of manufacture with regard to both materials
and labor, and which accordingly is then susceptible of low prices
of sale to the consuming public, thereby making such racket handle
and desiccant dispensers economically available to the buying public.
Still yet another object of the present invention is to provide
a new and improved racket handle and desiccant dispenser which provides
in the apparatuses and methods of the prior art some of the advantages
thereof, while simultaneously overcoming some of the disadvantages
normally associated therewith.
Still another object of the present invention is to provide a new
and improved racket handle and desiccant dispenser wherein a plurality
of axially aligned valves underlie a magazine formed with a racket
handle to selectively apply a desiccant powder over discrete portions
of a racket handle.
These together with other objects of the invention, along with
the various features of novelty which characterize the invention,
are pointed out with particularity in the claims annexed to and
forming a part of this disclosure. For a better understanding of
the invention, its operating advantages and the specific objects
attained by its uses, reference should be had to the accompanying
drawings and descriptive matter in which there is illustrated preferred
embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS.
1 to 5 thereof, a new and improved racket handle and desiccant dispenser
embodying the principles and concepts of the present invention and
generally designated by the reference numeral 10 will be described.
More specifically, it will be noted that the racket handle and
desiccant dispenser 10 essentially comprises a conventional racket
head 11 and an associated downwardly depending aligned handle 12.
The handle 12 is formed with a top compartment 17 overlying an elongate
magazine cavity 13 with an underlying first chamber 14. The top
compartment 17 the magazine cabinet 13 and the first chamber 14
contain an axially centered first plunger rod 16 reciprocatably
therethrough. The top compartment 17 houses a spring 19 with a cup-shaped
follower 18 at an uppermost portion of the spring with the plunger
rod 16 extending through orthogonal walls containing respective
outer and inner seals 17a and 17b to prevent contamination and intrusion
of the first chamber 14 and provide a barrier to prevent contamination
of a desiccant powder positioned within the magazine cavity 13.
A pivoting plug seal 13a of preferably resilient construction enables
access to the interior of the magazine cavity 13 by a fill conduit
13b. The cup-shaped spring follower 18 is fixedly secured to the
plunger rod 16 whereupon depressing of the plunger rod 16 carries
the spring follower 18 therealong and compresses spring 19 whereupon
release of the plunger rod 16 biases the plunger rod 16 to its initial
position, as illustrated in FIG. 2 for example.
A valve, including a first diaphragm valve seat 20 formed of a
resilient web material with the central aperture therethrough, defines
a lowermost end wall of the magazine cavity 13 and includes a first
spherical plug 21 fixedly secured to the plunger rod 16 whereupon
depressing of the plunger rod 16 against the bias of spring 19 vertically
displaces the spherical plug 21 from its seat on the diaphragm valve
seat 20 and allows a desiccant powder to travel and be directed
through by a conical directed surface 20a at an uppermost portion
of the valve seat 20 into the first chamber 14. The first chamber
14 includes plural pairs of aligned first chamber passageways 14a
(as illustrated in FIG. 4) and thereby distributes a desiccant powder
along an uppermost surface of the grip portion "G" of
the handle 12.
The plunger rod 16 includes a first plunger rod extension 16a depending
and extending axially aligned with the plunger rod 16 and beyond
the first spherical plug 21 and directed into an axially aligned
bore of a support bearing 22 positioned within the central cavity
24 within the handle 12. The central cavity 24 includes plural pairs
of conduits 23 surroundingly and axially displaced relative to the
support bearing 22 to enable desiccant powder to be directed from
the magazine cavity 13 through the first chamber 14 then through
the conduits 23 and into the central cavity 24 whereupon a second
plunger rod 25 formed with a second plunger rod extension 25a extends
into a lowermost portion of the bore of the support bearing 22.
A second spherical plug 26 is fixedly secured between the second
plunger rod 25 and the extension 25a and is normally biased upon
and overlies a central opening within a second diaphragm valve seat
27. A conical directing surface 27a formed at an uppermost portion
of the diaphragm valve seat 27 directs the desiccant powder therethrough
upon depressing of the plunger rod 25 extending outwardly of the
handle 12 and into a second chamber 15. Like the first chamber 14
the second chamber 15 includes a plurality of aligned second chamber
passageways 15a to direct desiccant powder about a lowermost portion
of the handle 12. In this manner, desiccant powder is selectively
directed onto selective portions of the handle 12 dependent on user
Similarly, a lower spring 29 includes a cup-shaped lower spring
follower 28 fixedly secured to the second plunger rod 25 to return
the plunger rod 25 to its original position upon release thereof.
Outer and inner seals 30a and 30b respectively seal the orthogonally
enclosing walls of the lower compartment 30 from contamination to
ensure longevity of operation of the instant invention.
As to the manner of usage and operation of the instant invention,
the same should be apparent from the above disclosure and accordingly
no further discussion relative to the manner of usage and operation
of the instant invention shall be provided.
With respect to the above description then, it is to be realized
that the optimum dimensional relationships for the parts of the
invention, to include variations in size, materials, shape, form,
function and manner of operation, assembly and use, are deemed readily
apparent and obvious to one skilled in the art, and all equivalent
relationships to those illustrated in the drawings and described
in the specification are intended to be encompassed by the present
Therefore, the foregoing is considered as illustrative only of
the principles of the invention. Further, since numerous modifications
and changes will readily occur to those skilled in the art, it is
not desired to limit the invention to the exact construction and
operation shown and described, and accordingly, all suitable modifications
and equivalents may be resorted to, falling within the scope of
