BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an exploded view of a surfboard 10 simulating exerciser; FIG. 2 is a perspective view of the surfboard simulating exerciser; and FIGS. 3 and 4 are side plane views illustrating the operation of the surfboard simulating exerciser.

15 DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 1-3, a surfboard simulating exerciser comprises a base 10 including a longitudinal track 11 disposed or provided on one end thereof, such as disposed on the front portion thereof and extended 20 along the longitudinal axis or direction of the base 10. The base 10 includes two studs 12, 13 extended upward from the rear portion thereof. A sprocket 31 has a spindle 310 rotatably supported on the stud 12, and two cranks 311, 312 are secured to the spindle 310 for 25 rotating or driving the sprocket 31 when the cranks 311, 312 are rotated or cycled by the users. A weight or a flywheel 32 and another sprocket 34 are secured

4 - together and rotatably secured on the stud 13 with a shaft 37, and are rotatable relative to the base 10 with the shaft 37 in concert with each other. A chain 33 is engaged over the sprockets 31, 34 for allowing 05 the flywheel 32 to be rotated or driven by the cranks 311, 312.

A lever 21 includes a foot support or a surfboard 22 disposed thereon, such as disposed on the front portion thereof, and includes a pair of ears 23 10 extended downward from the front portion thereof for rotatably securing or attaching with a roller or a wheel 24 which is rotatably or slidably engaged on the track 11. The wheel 24 includes two side stops 241 extended radially outward therefrom and engaged with IS the track 11 for guiding the wheel 24 to move along the track 11 and for preventing the wheel 24 from being disengaged from the track 11. The lever 21 includes a rear end pivotally or rotatably secured to the crank 311 with a pivot pin 29, such that the rear portions of 20 the lever 21 and the surfboard 22 may be moved or cycled by the crank 311, and such that the front portion of the surfboard 22 may be moved along the track 11 in a reciprocating action. The lever 21 may include a one-integral-piece structure, or may include 25 an extension 27 adjustably secured therein and adjustably secured thereto with a fastener 28 or the like, for allowing the extension 27 to be adjusted

5 - relative to the lever 21, and for adjusting the surfboard 22 relative to the cranks 311, 312.

A handle device 40 includes a tube 42 having a lower portion pivotally secured to the base 10 with a 05 pivot axle 47, and a bar 43 having a lower portion slidably engaged in the tube 42 and adjustable secured to the tube 42 with a fastener 432. The bar 43 includes a handle 48 provided thereon and includes a number of holes 431 formed therein for engaging with the fastener 10 432 and for adjustably securing the bar 43 to the tube 42. A link 41 is pivotally coupled between the tube 42 and the other crank 312, such that the sprockets 31, 34 and the flywheel 32 may be rotated or driven by the handle device 40 via the link 41 and the cranks 311, 15 312.

In operation, as shown in FIGS. 3 and 4, the user may stand or may be supported on the surfboard 22, and may pull or push or actuate or rotate the handle 48 relative to the base 10 about the pivot axle 47, in 20 order to rotate or to cycle the sprocket 31 and the cranks 311. 312, and in order to move the rear portion of the lever 21 in the circular path around the spindle 310, and in order to move the front portion of the surfboard 22 along the track 11 in the reciprocating 25 action. The surfboard 22 may thus be moved in a surfboard simulating or exercising movement.

When or after the user has been experienced to

- 6 - work on or to use the surfboard simulating exerciser, the user may remove the bar 43 and the handle 48, and may operate the surfboard simulating exerciser without the handle 4B. It is to be noted that the users may 05 also actuate or operate the surfboard simulating exerciser without disengaging or removing the bar 43 and the handle 48 from the base 10. The provision of the flywheel 32 may apply a resistance force against the movement of the cranks 311, 312 and thus the 10 surfboard 22.

It is further to be noted that the sprockets 31, 34 and the chain 33 may also be replaced with the gear transmission device, or with a pulley-andbelt transmission device, or the other transmission devices.

IS The foot support or the surfboard 22 may also be actuated or operated with the actuating mechanisms or devices as disclosed or taught by U.S. Patent No. 4,749,180 to Boomer, and U.S. Patent No. 5,904,636 to Chen, or with the other actuating mechanisms,.
