Dalebout teaches (column 7, lines 46-55) that the bolt member
156 and the nut member 166 together constitute an adjusting
means for adjusting the frictional resistance to movement of
the pedal means 34, 36 to the frame 16, 18. Whitelaw teaches
(column 3, lines 25-45) that the resistive force of the
friction member 56 may be varied by adjustment of the
adjusting cap 49 to increase or decrease the force imposed on
the friction member. Lastly, Hughes teaches (column 1, line
41, to column 2, line 51) a body exerciser having an
adjustable calibration member that can increase or decrease
the force imposed on the members (i.e., rotatable members 26
and stationary members 27 shown in Figure 3). It is our
opinion that these teachings would have suggested to one of
ordinary skill in the art at the time the invention was made
to make the resistance means of Airy in view of Dalebout
adjustable in order to provide a program for varying the
resistance force over a portion of movement in accordance with
the program at different angles between the first and second
sections.
