Torsion and gripping type exercise device for total arm development

An exercise apparatus which can be variously grasped while different torsion or other muscular movements are performed; the apparatus including a long hollow cylindrical bar having an enlarged circular handhold at each end, each handhold having an annular groove for receiving the fingers, a pair of spaced apart, short legs extending perpendicular to the bar, each outer end of the legs having a large circular foot which can alternately serve as handholds and a center of the bar having openings on opposite sides for the thumb and fingers of a user to permit squeezing of a sponge positioned in the center of the hollow bar.

This invention relates generally to exercisers for purposes of muscular 
development. 
A principle object of the present invention is to provide an exercise 
device which gives a total arm development. 
Another object is to provide an exercise device which can be made for use 
by either adults or children so to promote good health and body-building 
to all. 
Further objects of the invention will appear as the description proceeds.

Referring now to the drawing in greater detail, the reference numeral 10 
represents an exercise device for total arm development according to the 
present invention wherein there is an elongated, straight, cylindrical bar 
11 which at its opposite ends has an enlarged, circular handhold 12 
stationary therewith. Each handhold is of a size so that it can be 
comfortably grasped within a hand 13, as shown in FIG. 3; each handhold 
having an annual groove 14 for receiving the fingers 15 and thumb 16 
therewithin. 
Along a longitudinal side of the bar, there are a pair of parallel, spaced 
apart, short legs 17 extending perpendicular to the bar. Each outer end of 
the legs is integral with a circular foot 18 having a same diameter as 
handholds 12. 
Thus, the feet serve either to support the device 10 upon a supporting 
surface 19, such as a floor, as shown in FIG. 2, or else serve as 
handholds, as shown in FIG. 3, for being grasped by the hands. 
A longitudinal central portion of the bar is made hollow as shown at 20, 
and a resilient sponge or cushion 21 fills this interior. A circular hole 
22 on one side of the bar, for receiving a thumb 16, and a crescent shaped 
slot 23 on an opposite side thereof for receiving the four fingers 15 when 
the hand grasps around the center of the bar, as shown in FIG. 5, so to 
squeeze the sponge. 
The entire device is preferably made of a smooth-surfaced hard plastic 
material so to allow a firm or slidable grasp thereof, depending on the 
grasping force that is applied thereto. 
The device with exception of the sponge, is entirely rigid with no moving 
part. 
In the FIG. 2, the two hands, spaced apart, grasp around the circular bar. 
As indicated by opposite extending arrows 24 and 25, in FIGS. 2, 3 and 4, 
the hands can apply an opposite direction force against the device so to 
develop various muscles of fingers, hands, wrists and entire arm. 
It is thus apparent that the device may be used in at least the four ways 
as illustrated in the drawing. Additionally, it may be used with the bar 
in a vertical position, hands may be slided along the bar toward or away 
from each other, or the device may be used in numerous other ways as a 
person may discover for himself while exercising. 
While certain novel features of this invention have been shown and 
described and are pointed out in the annexed claims, it will be understood 
that various omissions, substitutions and changes in the forms and details 
of the device illustrated and in its operation can be made by those 
skilled in the art without departing from the spirit of the invention.
