flared opening and inwardly projecting portions at its extreme
outer end, a bottom plate closing said handle member at said end
and helping this end to hold its form, being wedged between said
inwardly projecting portions and the end of said ribs.
2. A racket characterized in accordance with claim 1, wherein said
one-piece handle member comprises a sheath which is slipped over
said shank and which is removably attached to said shank.
3. A racket characterized in accordance with claim 1, wherein the
sidewalls of said tube comprise an integral unit; and said tube has
an eight-sided cross section at right angles to the longitudinal
axis of said tube.
Description
The invention relates to a racket which comprises a frame and a
shank which connects to the frame and which is provided with a
handle or grip.
By the known rackets of this kind, which are used for playing
various games and sports, among others tennis and badminton, the
grip is formed by a thickening of the shank itself which is nearly
always made of wood. This thickening is then also provided with a
hand gripping covering such as leather. The grip is thus integral
with the remainder of the racket. The construction of such known
rackets is thereby relatively complicated and consequently such
rackets are relatively expensive. Moreover, the grip of each racket
has specific dimensions and a specific weight, with the result that
the racket salesman has to have many rackets in stock which differ
only by the size and/or the weight of the grip thereof. Moreover,
the grips, even if they belong to rackets of one and the same size,
are not always identical. Should a player who already owns a racket
wish to have a racket with a grip having another size or another
weight, or if his racket grip has been damaged, he will have either
to buy another racket or to have his racket grip altered by a
complex and costly operation. Should the hand gripping covering
only be damaged, said handgripping covering may be replaced which,
however, requires much work.
The invention has for its object to obviate said drawbacks and to
provide a racket the construction of which is simple and
inexpensive and which allows simply and rapidly to obtain a new
size or another weight for the racket grip or to provide said
racket with a new grip handgripping covering.
For this purpose the grip is removably attached to the shank.
In a particular embodiment, the grip is comprised of a sheath or
tube which is slipped over the shank and which is removably
attached to said shank.
Said tube is preferably provided on the inner side of the sidewalls
thereof with ribs.
In an advantageous embodiment of the invention, the grip is
removably attached to the shank by means of at least one screw.
The shank is preferably provided with an opening in which a plug of
a material which is at least somewhat resilient, is wedged, whereby
the screw is screwed into said plug.
With said latter embodiment, it is possible to screw in and out
repeatedly the screws to remove the grip without any danger of said
screws becoming loose in the shank. Indeed, should the screw become
impossible to tighten in the plug, it is only necessary to replace
said plug.
Other details and features of the invention will stand out from the
description given below by way of nonlimitative example and with
reference to the accompanying drawings, in which:
FIG. 1 is a front view of a racket according to the invention.
FIG. 2 is a section along line II--II of FIG. 1.
FIG. 3 is a section along line III--III of FIG. 1.
In the various figures, the same reference numerals pertain to
similar elements.
The racket according to the invention comprises a frame 1 in which
the strings 2 are stretched. The frame 1 connects to a shank 3 with
a rectangular cross section. The frame 1 and the shank 3 are made
of laminated wood. To the end of the shank 3 is removably attached
a grip or handle 4, 5.
Said grip is a tube or sheath which forms an eight-sided prism with
sidewalls 4 and a bottom 5. On the inner side of those sidewalls of
the tube which lie opposite the larger sides of the shank 3, that
is, on the inner side of those sidewalls 4 which are in parallel
relationship with the plane in which the frame 1 extends, are
provided two ribs 6 which run over nearly the whole length of the
tube and which come with the lower end thereof substantially
against the above-mentioned side of the shank 3. The width of said
ribs 6 is about 5 mm. On the inner side of those sidewalls 4 of the
tube which face the smaller side of the shank 3 is also provided a
rib 7. The ribs 7 also run over substantially the whole length of
the tube and they nearly lie against the shank 3. The width of said
ribs 7 is about 1 mm. At the one end of the tube the sidewalls 4
spread out somewhat from one another. By this end the bottom 5 is
wedged between the ends of the ribs 6 and 7 on the one hand and the
slightly inwardly projecting outer edges of the sidewalls 4, on the
other end. The sidewalls 4 comprise a plastic unit. The bottom 5 is
also made of plastic. At the other end of the tube, to each one of
those two sidewalls 4 which face the larger sides of the shank 3
connects a lug 8 in which both ribs 6 on said sidewalls 4 end.
The handle or grip 4, 5 is attached to the shank 3 with two screws
9 which go through each one of the opposite lugs 8 and which are
screwed in the shank 3. Said shank 3 is provided for this purpose
with an opening which opens in the larger sides thereof, opposite
the openings in lugs 8 when the grip is completely slipped over the
shank 3. Inside the shank opening is wedged a plastic plug 10. The
screws 9 are then screwed in said plug 10. In this way, there is no
danger of the screws 9 becoming loose in the shank 3 after
repeatedly screwing and unscrewing said screws 9. Should the screws
9 no longer find a hold in the plug 10, it is only necessary to
replace said plug 10.
The sidewalls 4 of the grip are further lined over the whole length
thereof with an helically wound strip of leather 11, the ends of
which are attached to said sidewalls 4.
In the above-described racket, it is thus possible in a simple and
fast way to separate the grip 4, 5 from the shank 3 by unscrewing
the screws 9. The assembly of the racket is thus also much easier
and less costly. As the grips may be manufactured separately, one
may obtain for some particular racket size, a grip which has always
the same size and the same weight. The dealer instead of having to
stock a series of rackets with the same size but with different
grips, may now simply have one racket of said size and various
grips therefor. When the handgripping covering strip 11 is damaged
or broken, it is also possible to replace the complete grip instead
of fitting another strip 11. Should someone want a grip with
another weight or another size, the racket grip may very rapidly be
replaced by another one. Inside the grip there may of course also
be arranged small weights to influence the balance and the weight
of the racket.
It must be understood that the invention is in no way limited to
the above embodiments and that many changes may be brought therein
without departing from the scope of the invention as defined by the
appended claims.
For instance the grip does not necessarily have to be made of
plastic. The grip need not necessarily have a handgripping
covering. The tube surface could be so manufactured that it appears
and feels like a leather handgripping covering.
The grip does not necessarily have to be attached to the racket
grip as described above. Said grip may also, for instance, be
attached with a screw that goes through the tube bottom.
