Description
PRIORITY
[0001] The applications claims priority from Provisional
Application No. 61/997,309 filed on May 29, 2014.
FIELD OF THE INVENTION
[0002] The invention of the present application improves a
previously existing grip free hand weight. Specifically, the grip
free hand weight of the present invention improves the existing
grip free hand weight by providing a method of changing the core
weight of the device at the user's convenience.
BACKGROUND OF THE INVENTION
[0003] As depicted in U.S. Pat. No. 4,813,669, there exists in the
prior art a grip-free hand weight to exercise a user's arms, hands
and wrists. The grip free hand weight of the prior art is a fixed
weight device, and does not allow the user to change the weight of
the device at will.
SUMMARY OF THE INVENTION
[0004] Accordingly, it is an object of the present invention to
provide an exercise device, having a substantially-spherical,
relatively thin-walled housing with an opening formed therein
whereby the hand of the user may be inserted through the opening
into the housing, wherein said housing includes a cavity portion
capable of receiving and retaining a removable weight.
[0005] It is a further object of the present invention to provide
an exercise device wherein the removable weight is screwed into the
housing.
[0006] It is yet another object of the present invention to provide
an exercise device wherein the removable weight is contained within
a canister
[0007] It is also an object of the present invention to provide an
exercise device, comprising a substantially-spherical, relatively
thin-walled housing having an opening formed therein whereby the
hand of the user may be inserted through the opening into the
housing, wherein said housing includes contains two cavity portions
that are diametrically opposed in relation to one another.
[0008] In another embodiment, it is an object of the present
invention to provide an exercise device, comprising a
substantially-spherical, relatively thin-walled housing having a
diametral axis, wherein the housing has a pair of complementary
semi-spherical housing portions, the housing portions capable of
being connected and disconnected to each other, means for retaining
a removable weight, the means being molded within the housing,
wherein the removable weight is disposed within the housing
substantially coincident with the diametral axis thereof, means for
joining the semi-spherical hemispherical portions and retaining the
weight, the housing having an opening formed therein where by the
hand of the user may be inserted through the opening in the
housing.
[0009] This and other objects of the present invention will become
apparent from a reading of the following specification, taken in
conjunction with the enclosed drawings.

[0014] FIG. 5 is a cross section view of an alternate embodiment of
the exercise device of the present invention.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0015] With reference to FIGS. 1 and 2, there is illustrated the
exercise device 10 of the present invention. The exercise device 10
includes a substantially-spherical relatively thin-walled housing
15 which includes a removable weight 20 contained within a cavity
portion 25 formed therein. The housing 15 further has an opening 30
formed therein substantially tangentially of the housing 15,
whereby the hand of the user may be inserted into the housing 15
for use of the exercise device 10.
[0016] The substantially-spherical relatively thin-walled housing
15 may be a single molded unit or be comprised of multiple pieces
which are joined together by means known in the art. The weight 20
has an end cap 35 which has a gripping means 40 enabling the user
to grasp an end of the weight 20 for changing the weight of the
exercise device 10. The end cap end or the opposite end of the
weight 20 include means for securing the weight 20 into the housing
15. In the preferred embodiment, these means are a threaded end
which screws into the interior of the housing 15, but the securing
of the weight 20 into the housing 15 may be accomplished by any
means known in the art.
[0017] In an alternate embodiment of the preferred embodiment, as
seen in FIG. 3, the exercise device 10', the substantially
spherical housing 15' has two diametrically opposed cavity portions
25A and 25B therein, each cavity portion 25A,25B, capable of
receiving a weighted canister.
[0018] With reference to FIGS. 4 and 5, there is illustrated
another alternate embodiment of the exercise device 10'' of the
present invention. The exercise device includes a
substantially-spherical relatively thin-walled housing 15'' having
a diametral axis designated at A. The housing 15'' includes a pair
of housing portions 15''A and 15B'' joining at a common midplane B.
Each of the housing portions 15A'' and 15B'' is preferably
substantially hemispherical and identical to one another; moreover,
the housing halves 15A'' and 15B'' are molded from a suitable
plastic material, such as a polycarbonate having relatively high
impact strength. However, it will be expressly understood and
appreciated by those skilled in the art that the present invention
is not so limited.
[0019] The housing 15'' includes a suitable keying means between
the pair of hemispherical portions 15A'' and 15B'', whereby the
hemispherical portions are retained together and form the
substantially spherical housing 15''. However, the keying means
must be able to be disconnected with relative ease by the user to
allow interchangeability of the weight 20'' contained in the
housing 15''. Each of the thin-walled housing portions 15A'' and
15B'' has a concave inner walled portion forming a circular recess
for containing the weight 20''.
[0020] With further reference to FIG. 5, the weight means comprises
a small threaded brass insert 50 which is molded into one of the
hemispheres of the exercise device 10''. Subsequently, a single
screw 60 is used to hold the weight 20'', which may be a hollow
steel core in place within the exercise device 10'', and at the
same time to tie the two hemispheres together. If a user desires to
change the weight 20'', he simply has to unscrew the single screw
60, pull apart the two hemispherical portions 15A'' and 15B'' to
access the weight, which is then pulled out of the exercise device
and replaced with another weight 20'' of the user's choice. The
single screw is then used to join the two hemispherical portions
15A'' and 15B'' again. Obviously, many modifications may be made
without departing from the basic spirit of the present invention.
Accordingly, it will be appreciated by those skilled in the art
that within the scope of the appended claims, the invention may be
practiced other than has been specifically described therein.
