The control rod 83 has an end with a pivotal hole 11 831 for pivotal engagement with the movable seat 82. The other end of the 12 control rod 83 includes an engaging portion 832. A spring 833 is attached 13 between the engaging portion 832 and the movable seat 82 for biasing the 14 engaging portion 832 of the control rod 83 to engage with one of the positioning holes 812 of the fixing seat 81. In operation, the user may pivot the 16 control rod 83 to disengage the engaging portion 832 from the positioning 17 holes 812 and then slide the movable seat 82 relative to the fixing seat 81 until 18 the seat 7 is in a proper position relative to the handle 1 and the control rod 83 19 is then released to reengage the engaging portion 832 with a desired one of the positioning holes 812. Thus, the user may adjust the engaging portion 832 of 21 the control rod 83 to selectively engage with one of the positioning holes 22 of the fixing seat 81 to thereby adjust position of the seat 7. The spring 23 may provide an appropriate resistance during movement of the movable seat 24 82.
Referring to Fig. 9, the user may sit on the seat 7 with the feet resting on 26 the footrests 6 and with the hands operating the handlebar 1 to move back and 1 forth to thereby move the combined skateboard scooter/exerciser forward 2 while achieving a rowing-like exercise effect.
3 Although the invention has been explained in relation to its preferred 4 embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as 6 hereinafter claimed.
