Abstract
A weighting device for use on an athletic ball striker as during handle swinging of the striker comprising a receptacle having an opening via which the ball striking portion is received into the receptacle, with the handle projecting from the receptacle, a retainer carried on the receptacle to be fastened in a position for retaining the receptacle in generally enclosing relation to the ball striking portion, and weighting structure carried by the receptacle to add substantial weight to the striker for use as in striker practice swinging, the retainer including a foldable flap that retains the receptacle to the striker during such practice swinging, the striking may for example comprise a baseball bat, or a tennis racket.
Description
BACKGROUND OF THE INVENTION
This invention relates generally to swinging of ball strikers, as for example baseball bats, tennis rackets, and racket ball rackets and more particularly concerns removably adding weight to a ball striker, for practice swinging purposes.
When baseball players warm-up, or train, they commonly use two bats, and swing them in unison a few times to loosen muscles. Also used are a heavy bat or weighted rings. Holding and swinging two bats is awkward, uncomfortable, and does not achieve the right feel, needed as by gripping and swinging only one bat but one bat does not achieve additional weight as can be provided by two bats. Use of a heavy bat, and/or weighted rings is also disadvantageous. There is need to overcome this dilemma, in a simple, effective and efficient manner, as is now provided by the present invention. In a similar manner, there is need to provide additional weight to other ball strikers, such as tennis rackets, for example. Other strikers include racket ball rackets, cricket paddles, hockey sticks and table tennis paddles.
SUMARY OF THE INVENTION
It is a major object of the invention to provide a simple and effective weighting device meeting the above need. Basically, the device comprises:
a) an elongated receptacle having an opening via which the striker ball striking portion is received into the receptacle, with the handle projecting from the receptacle,
b) a retainer carried on the receptacle to be fastened in a position for retaining the receptacle in generally enclosing relation to the striker ball striking portion,
c) and weighting structure carried by the receptacle to add substantial weight to the striker, for use as in striker practice swinging,
d) the retainer including a flap that folds over and releasably attaches to a surface carried by the receptacle, to effect retention of the weighted receptacle to the striker during the practice swinging.
As will be seen, the retainer flap or strap preferably is carried to extend at least part way along or about the receptacle, when closed on the ball striker, and hook and pile fastening material such as VELCRO may be provided to adhere the flap or strap in fastening position. Such closure preferably at least partly covers the opening in the receptacle that passes the ball striking portion of the striker, to prevent release or separation of the weighted receptacle during swinging.
Another object includes provision of a receptacle having multiple wall portions, and the weighting structure is preferably located at or proximate at least one of such wall portions.
In addition, the weighting structure typically includes metallic material, solid or flowable; it is typically concealed by the receptacle, and it may include separate localized metallic zones or portions. It may be sewn or otherwise held in a pocket or pockets provided by the receptacle, and at the end or at a side or sides of a ball striking portion of the striker retained in the receptacle.
Yet another object includes location of the weighting material in a pocket provided by the receptacle, and in this regard the pocket or pockets may enable selective use of the material in one or more pockets, for adjustable weighting, as to positioning, or as to selected weighting; or both. The pocket or pockets may be sized to fit different strikers or all sizes of strikers.
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

DETAILED DESCRIPTION
Referring to
FIGS. 1-5
, a weight holder device is shown at
10
, for use on a ball striker such as a baseball bat
100
as during warm-up swinging of the bat. It includes a receptacle
11
having an elongated opening or split
12
via which, or through which, a ball striking portion
13
of the striker is received. Portion
13
may also be referred to herein as a “head”. The receptacle has a front side
11
a,
a rear side
11
b,
a distal end
11
c,
and a proximal end at
11
d.
In this example, the opening
12
extends from the proximal end lid to a convergence lie in the front side
11
a,
and may have a long dimension indicated at
14
in FIG.
2
. That dimension is typically sufficient to allow entry of the head
13
endwise, sidewise through the opening, and endwise into the receptacle forward sleeve portion
11
f,
as well as easy removal from the receptacle. The receptacle typically consists of flexible fabric or other material which is tough and durable, as for example synthetic resinous (plastic) material.
The elongated receptacle preferably has wall portions, and typically at least two of the following:
i) an elongated front side or first wall portion
16
to extend adjacent, or proximate a side of the head
13
of the bat
100
;
ii) a rear side or second inner wall portion to extend adjacent or proximate the head rear side;
iii) a forward or third wall portion
19
to extend forwardly of or adjacent the distal end of the bat head;
iv) a rearward or fourth wall portion
20
at the proximal end of the receptacle, and at the narrowed end
100
c
of the bat, near handle
100
a
of the bat.
The receptacle further defines a interior cavity or slot
22
receiving the head, and wall
16
is slit as at
18
, along part of the receptacle length, the slit intersecting proximal end
11
d.
Proximal end opening
100
d
of the receptacle intersects the slit
18
to form an enlarged opening
102
, for ease of bat reception. The narrowed portion
100
c
of the bat “lays into” opening
100
d.
As will be seen, a retainer is carried on the receptacle to extend and to be fastened in a position for retaining the receptacle in close fitting relation to the bat shank.
In the example, a retainer in the form of a strap
25
is shown in open position in
FIGS. 1 and 4
; and in closed position FIG.
5
. The strap is or may be integral with the proximal end wall portion
11
d
of the receptacle. The receptacle extents
18
a
and
18
b
turned open in
FIG. 4
, define a flap or flaps, that have forward and rearward angled edges
25
a
and
25
b,
convergent and intersecting at
11
e.
When flap
18
a
is folded at fold zone
25
d,
edge
25
a
folds over edge
25
b
and over the side
100
c
of the received bat, in close fitting relation. The flap
25
a
inner surface
25
f
may be retained to outer surface
25
g
of flap
18
b,
as by hook and pile attachment, after spiral winding of one flap over the other, enabling easy opening and closing of the flap
18
a
and its adjustable firm closing of the described enlarged opening
102
, as well as tightening to closely fit the receptacle to the bat ball striking portion, while at the same time providing very firm attachment of the device to the bat, preventing loosening and/or detachment, as during club swinging. See FIG.
5
. Strap
25
may be wound about the closed flaps, at the proximal end of the receptacle, to effect at least part closing of proximal end opening
102
, and VELCRO on the strap surfaces holds it closed. Hook and pile structure preferable extends over a wide inner extent of folded back flap
18
a,
and a wide outer extent of flap
18
b,
as shown, so that the flap
18
a
can be adjustably attached in selected positions (tightened and loosened), considering the different cross sectional sizes of different bats to be protectively confined. Therefore, versatility of the device is enhanced. The majority of opening
102
is covered by the flap, as in FIG.
5
. The closed flaps have taper toward handle
100
a,
as seen in
FIG. 5
, due to bat shank taper, locking the receptacle to the bat against endwise separation as during practice swinging.
Further in accordance with the invention, weighting structure is carried by the receptacle to add substantial weight to the head weight, for use in bat swinging; and it is typically carried by a receptacle inner sleeve
40
that fits endwise into receptacle outer sleeve
41
. See
FIGS. 2 and 3
.
The weighting structure is so carried that it is located at or proximate one of the following:
vi) at least one of such wall portions on at least one sleeve;
vii) at least two of such wall portions on at least one sleeve;
viii) at least three of such wall portions, on at least one sleeve.
In
FIG. 2
, the weighting structure includes three metallic (steel particles for example) weights
35
-
37
located in pockets
35
a
-
37
a
at or near the distal end of sleeve
40
. Such pockets may be formed by receptacle or sleeve material. The thickness of each weight is typically less than its length and less than its width, as shown. The pockets may be closed to hold the weights in positions, as described. The weights are retained in selected position or positions as by the sleeve or sleeves as shown, and the pockets may be selectively attached (for example sewn) to sleeve wall fabric, as by hook and pile elements, or other structure. The pockets can be adjustably or permanently attached to sleeve
40
.
Weight material may alternatively consist of metallic granules, or non-metallic pebbles or particulates.
FIGS. 6-8
show a receptacle
200
shaped like a tennis racket ball striking head portion
204
(tear drop shape periphery), and having a flap
201
to close over a side
202
of the receptacle and retain the head in position. See flap VELCRO at
201
a
and VELCRO
202
a
on
202
. Handle
204
a
projects from the receptacle end opening
200
a
in FIG.
7
. The latter intersects a side opening
200
b
to form an enlarged opening through which head portion
204
is placed or received. Weights
210
are carried in pockets
211
in or on the receptacle. When the flap
201
is closed, the head portion
204
is trapped in the receptacle to prevent separation during practice swinging. A carrier loop is provided at
215
; and a zipper at
216
on receptacle side
200
a′.
In all forms, any number of more weight can be used.
In all forms the retainer can incorporate a buckle or buckles for tightening purposes.
FIG. 9
shows three receptacles
111
a,
111
b
and
111
c
suspended by support structure, as for example the mesh wires
112
of a fence
113
. Each receptacle may be of the type described above, as at
11
, i.e. for reception of a baseball bat, or other device having a handle. Receptacle
