ADJUSTABLE WEIGHT WORKOUT STONE
Abstract
A fabricated workout stone to provide an easily assembled and
transportable equivalent of a solid cast concrete spherical stone.
The fabricated steel stone includes a two-part shell body with a
weight receiving rod extending inside from one shell part. A
threaded opening in the free end of the rod receives a retaining
bolt extending through the opposite shell securing the spherical
shells together. Multiple weight lifting bar weights of varied
sizes and mass are slidably secured on the rod to vary the total
weight of the fabricated stone when assembled for use.

DETAILED DESCRIPTION OF THE INVENTION
[0017] Referring to FIGS. 1 and 2 of the drawings, an adjustable
weight training and competition stone 10 of the invention can be
seen having a pair of hollow half hemisphere shells 11 and 12. Each
of the sphere shells in this example is preferably made of metal of
a known thickness so as to be self-supporting and shape retaining
when joined together during use as will be described in greater
detail hereinafter.
[0018] The half sphere shell 11 is defined as a "base shell" having
an annular band 13 secured by welding along its interior perimeter
edge 14. The band 13 extends beyond a top edge 15 of the base shell
11 forming a continuous registration lip thereabout for receiving
the shell half 12 thereon during assembly.
[0019] A weight support and retainment rod extends centrally from
the interior of the base shell 11 as best seen in FIG. 1 of the
drawings. The rod 16 is welded in position and extends upwardly
beyond the trans-planar plane defined by the top edge 18 of the
base shell 11. The weight support and retainment rod 16 has a
plurality of longitudinally spaced vertically aligned transverse
apertures A extending there through in this example. The free end
16A of the rod 16 has a centered threaded bore 19 therein for
threadably receiving a corresponding physical retainment keyed bolt
20 that extends through a recessed aperture fitting 21 in the upper
spherical shell 12 in alignment with the rod 16 so when
registerably engaged with the base shell 11 by the hereinbefore
described upstanding registration lip as will be understood and
explained in greater detail hereinafter.
[0020] As assembled by referring now to FIG. 2 of the drawings, one
or more retaining rings 22 will be slidably engaged over the rod 16
and secured by a pin 23 extending through aligned apertures A' one
of which may be threaded and correspondingly so aligned transverse
aperture A in the rod 16 as hereinbefore described. A plurality of
apertured weights 24 of a traditional barbell type having a bar
engagement center opening are then selectively fitted on the rod 16
depending on their size and weight in a stacked relationship until
the goal weight for the fabricated stone is reached. A
corresponding apertured locking ring 25 and pin assembly is then
slidably positioned on the rod 16 to secure the multiple weights 24
so positioned. A compressible spacer ring 26 of resilient material
may be required to be positioned between the last weight 24A and
the retaining ring assembly 22 to assure that the weights 24 are
secured against movement on the rod 16 during use.
[0021] The upper spherical shell 12 is then aligned on the base
shell 11 via its registration lip and joined to the base shell 11
by the threaded keyed bolt 20 positioned through the bolt
engagement fitting 21 within the upper spherical shell 12 as best
seen in FIGS. 1 and 5 of the drawings. The bolt engagement fitting
21 provides for a recess 21A therewithin to retain the bolt 20 as
it is threadably received within the rod 16 as illustrated best in
FIG. 1 of the drawings.
[0022] It will be seen that the bolt 20 can also be used to assist
in lifting the sphere by selective engagement with a handle 27
illustrated in FIGS. 9 and 10 of the drawings. The handle 27 has a
threaded fitting extending from its base which can be threadably
secured into a threaded fitting in the shell bolt opening so that
just the shell can be engaged and lifted during assembly or
disassembly of the alternate adjustable weight training and
competition stone.
[0023] By the utilization of split lightweight shells with a center
support post for placing and receiving a plurality of individual
uniform weight lifting weights that a lightweight transportable
weightlifting stone assembly can be achieved.
[0024] The handle 27 also has attached extending allen wrench
fittings 27B extending in oppositely disposed relation from the
hand engagement portion 27C of the handle 27.
[0025] Referring now to FIGS. 5 and 6 of the drawings, an alternate
adjustable weight training and competition stone 30 can be seen
having hollow shells 31 and 32. The base shell 31 has the same
shell joining alignment band at 32A welded therein as seen in the
primary form of the invention.
[0026] A solid centered weight support and retaining rod 33 extends
from within the base shell rod fitting 34 with a shell attachment
bolt receiving recessed threaded fitting 35 in its free end. A
plurality of spacer rings 36 are registerable over the rod 33
sequentially to space and support as needed a number of apertured
weights 37 positioned on the rod 33 as seen in FIG. 5 of the
drawings to obtain the desired weight required for use.
[0027] The spacer rings 36 are of varied dimensional thicknesses to
be mixed and matched as needed. An initial weight engagement end
support resilient washers 38 are slidably positioned on the rod 33
between the spacer rings 36 and the fittings 34. The resilient
washers 38 provide a compressive cushion on each of the respective
end surfaces of the stacked aligned spacer rings 36 on the support
rod 33.
[0028] By joining the respective shell spheres 31 and 32 by
attaching a threaded bolt 39 to the end of the rod 33, the selected
weights 37 are held immovable within the assembled spheres assuring
a uniform weighted stone mass which is essentially in competition
as will be understood by those skilled in the art.
[0029] It will be seen that corresponding number and by size
(height) spacer rings 36 are selectively positioned on the rod 33
to conform with the space displaced by the weight 37. As noted,
compressible resilient rubber washers 38 are then positioned at
respective ends to assure a firm compressed connection.
[0030] The spacing and orientation of the weights 37 and spacer
rings 36 and oppositely disposed resilient compressed washers 38
assures that the weight mass is centered on the rod 33 and
therefore within the adjustable weight training and competition
stone 30 when the shells 31 and 32 are fitted and retained together
as hereinbefore described.
[0031] Referring to FIGS. 5 and 6, a plurality of sphere
reinforcing ribs 40 are welded onto the interior surfaces 41 and 42
of the respective sphere halves 31 and 32 extending radially from
the corresponding rod base engagement fittings 34.
[0032] Each of the ribs 40 have a base portion 40A and an end
portion 40B. A contoured notch 41 is formed midway the combined
rib's length defining the respective portions to provide weight
clearance, if needed, adjacent rod end placement in certain weight
selection application requirements.
[0033] Spacer rings 36 are of uniform annular dimension with a rod
receiving opening centered therein at 36A. The respective
dimensional widths vary, as noted, and in this example one-quarter
to half inch to accommodate varied selection placement and
variations.
[0034] It will therefore be seen that a new and useful weight
training and competition stone 20 and 30 of the invention has been
illustrated and described and it will be apparent to those skilled
in the art that various changes and modifications may be made
therein without departing from the spirit of the invention.
Therefore, I claim:
