The present invention relates generally to an exercise 5 machine and more specifically to an exercise machine for permitting the windmilling of a user's arms and having a predetermined resistance thereto to achieve physical exercise. 10
Exercise machines of all types and configurations have been developed for toning up muscles, losing weight, physical therapy or the like. For example, U.S. j5 Pat. Nos. 3,640,527 to Proctor, 4,411,421 to Hershberger and 4,563,003 to Bugallo et al all show exercise machines designed to allow a user to reciprocate his or her arms for exercise purposes. U.S. Pat. Nos. 4,611,807 to Castillo and 4,749,182 to Duggan show exercise ma- 20 chines which allow the user to rotate the user's hands in a circular fashion for exercise purposes.
Many of these exercise devices are fine for exercising a particular part of the body but they tend to be so specialized that other exercise equipment is necessary 25 for exercising other parts of the body. Consequently, there is a need for exercise equipment which will be useful to exercise a number of muscles at one time.
DISCLOSURE OF THE INVENTION 30
The present invention relates to an exercise apparatus having a pair of arms which are rotatable about a horizontal axis to permit a user to grasp handles attached thereto and to windmill the user's arms so that the arms of the machine will rotate about an axis extending 35 through the shoulder joint which attaches to the user's arms. An adjustable resistance mechanism is provided to allow the user to adjust the resistance to rotation of the arms. The arms on the machine are adjustable in length from the rotational axis and an adjusting mechanism is also provided to adjust the distance of the rotational axis from the surface on which the user is standing.
An object of the present invention is to provide an ^ improved exercise apparatus.
Another object of the present invention is to provide an exercise apparatus for allowing a user to windmill the user's arms while keeping the elbows straight and having a controlled resistance thereto. 50
A further object of the present invention is to provide an exercise machine of the aformentioned type which has an adjustment to adjust to the arm length of any user.
A still further object of the present invention is to 55 provide an apparatus of the aformentioned type which has an adjustment to adjust for the height of the user to position the rotational axis of the arms through the shoulder joints of the user.
A still further object of the present invention is to 60 provide a handle apparatus on the aforementioned exercise apparatus which permits windmilling of the arms of the user without twisting of the wrists of such user.
Other objects, advantages, and novel features of the present invention will become apparent from the fol- 65 lowing detailed description of the invention when considered in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE
Referring now to the drawings wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 shows an exercise machine (10) constructed in accordance with the present invention. Referring to FIG. 4, it is noted that the exercise machine (10) includes a base having a floor engaging plate (11) having upstanding side elements (12) attached thereto. These side elements (12) are constructed of tubing (13) around the outside and metal plates (14) rigidly affixed to the pipe (13) by fasteners (15).
Support members (20) are pivotally attached to upright base structures (12) by a pin arrangement (22). The support members (20) are constructed of a tube (23) having side metal plates (24) attached thereto by fasteners (25). These support members (20) have one end biased downwardly by a tension spring (26) attached at one end (37) to the support member (20) and at the other
end (28) to the base (11). These two springs (26) will tend to cause the end with the arms (30) thereon to be up but the tension forces on the springs (26) can be overcome to move the end with the arms (30) thereon downwardly. 5
