## Title
Surfing exerciser

## Abstract

A surfing exerciser includes a base on the floor and a motor is disposed on the base with a wheel connected to an end of the motor and driven by the motor. A fame is disposed on the base and an arm has a first end pivotably connected to the frame. A second end of the arm is pivotally connected to a first end of a link, and a second end of the link is eccentrically pivotably connected to the wheel. A board is pivotably connected to the link so that a user stands on the board and the board is moved along a ∞-shaped path when the motor is activated.

## Background
FIELD OF THE INVENTION
The present invention relates to a surfing exerciser which employs links connected between a servo motor and a board which is moved along a ∞-shaped path so as to provide the user a imitation of surfing.
BACKGROUND OF THE INVENTION
A conventional exercisers that have pedals include step mounting exerciser and elliptical exerciser. The step mounting exercisers allow the user to alternately step the pedals along a substantially circular path and the elliptical exercisers allow the user to move legs in an elliptical path. These types of movement are not satisfied by the users and new type of movement is needed in the market.
The present invention intends to provide a surfing exerciser which has a board and the user stands on the board with his or her tow legs. The movement of the board is along a ∞-shaped path so that the user feels like surfing and may enjoy a new type of movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, the surfing exerciser of the present invention comprises a base 10 put on the floor and a support base 12 with a servo motor 50 disposed thereon are disposed on the base 10. A wheel 11 is connected to an end of the motor 50 and driven by the motor 50.
A frame 30 is disposed on the base 10 and an arm 31 having a first end pivotably connected to the frame 30 by a bearing. A second end of the arm 31 pivotally connected to a first end of a link 20. The first end of the link 20 is a U-shaped connection member 21 which includes a top surface and a board 22 is disposed on the top surface of the link 20. A second end of the link 20 is eccentrically pivotably connected to the wheel 11 at the pivot point 111.
As shown in FIG. 2-1, pivotal devices 220 are disposed between the board 22 and the link 23 so that the board 22 can be moved relative to the first end of the link 20. As shown in FIG. 2—2, two pedals 221 are pivotably connected to the board 22 so that the user may stand on the two pedals 221 by two feet and the two pedals 221 are moved relative to the board 22.
