BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a cycle exerciser, and more particularly to a hand driving cycle exerciser to be driven by hands of users. [0003] 2. Description of the Prior Art [0004] Various kinds of typical cycle exercisers have been developed, and comprise a pair of arm cranks to assist in the propulsion of the exerciser by utilizing power of the arms of the users. [0005] For example, U.S. Pat. No. 4,417,742 to Intengan discloses one of the typical cycle exercisers comprising a pair of arm cranks coupled to a pawl mechanism, in order to drive a rear wheel via a flexible shaft, in order to assist in the propulsion of the exerciser by utilizing power of the arms of the users. However, when rotating the arm cranks, the cycle exerciser may be unstable and the front portion of the cycle exerciser may swing or vibrate sidewise. [0006] U.S. Pat. No. 4,664,400 to Date discloses another typical cycle exerciser comprising a treadle-shaft crank coupled to a short crank and a long crank, and a handle coupled to the long crank, in order to form a see saw exercise vehicle, and to allow the exercise vehicle to be driven by hands of users. [0007] However, when the handle should be forced forwardly and rearwardly by the two hands of the users simultaneously, such that the center of gravity of the users may be moved forwardly and rearwardly, and such that some of the moving force of the cycle exerciser may be overcome by the forward and rearward movement of the users. [0008] U.S. Pat. No. 4,685,692 to Fullilove et al. discloses a further typical riding cycle exerciser driven over terrain by foot pedals operating on a sprocket shaft, and comprising hand cranks which operate through a flexible drive on foot operated sprocket shaft. However, similarly, when rotating the hand cranks, the cycle exerciser may be unstable and the front portion of the cycle exerciser may swing or vibrate sidewise. [0009] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional hand driving cycle exercisers. SUMMARY OF THE INVENTION [0010] The primary objective of the present invention is to provide a hand driving cycle exerciser for being stably driven by hands of users. [0011] The other objective of the present invention is to provide a hand driving cycle exerciser including a steering mechanism operatable by twisting or turning or rotating operation of users. [0012] In accordance with one aspect of the invention, there is provided a hand driving cycle exerciser comprising a base including a front portion having a front wheel device attached thereto, and including a rear fork attached thereto, a rear wheel rotatably attached to the fork of the base with an axle, to allow the rear wheel to be rotated relative to the fork of the base, two rotary members rotatably attached onto the rear wheel with unidirectional bearings, to allow the rotary members to be rotated relative to the rear wheel unidirectionally, two followers rotatably engaged onto the axle, and coupled to the rotary members, for unidirectionally rotating the rear wheel via the rotary members and the unidirectional bearings, two handles rotatably attached to the base, and a connecting device for connecting the handles to the followers respectively, to unidirectionally rotate the rear wheel via the followers and the rotary members and the unidirectional bearings with the handles. [0013] The base includes a pair of posts extended therefrom and each having a pin laterally extended therefrom to rotatably attach the handles to the base. Each of the handles includes a sleeve provided thereon and rotatably engaged onto the pins of the posts of the base respectively, to allow the handles to be rotated relative to the base in reciprocating action. Each of the handles includes an extension adjustably secured thereon, and having a hand grip provided on top thereof, for being grasped by users. [0014] Each of the followers includes a pole extended therefrom, and the connecting device includes two cranks secured to the poles and rotated in concert with the poles respectively, and a pair of levers coupled between the handles and the cranks, to allow the handles to drive the followers and the poles relative to the axle by the levers and the cranks. [0015] Each of the rotary members includes a plurality of notches formed therein, and each of the followers includes a plurality of teeth extended therefrom and engaged into the notches of the rotary members, to unidirectionally rotate the rear wheel via the rotary members and the unidirectional bearings. [0016] The base includes a front tube secured to the front portion thereof and extended vertically, a shaft rotatably secured in the front tube of the base to attach the front wheel device thereto, and a rotating device for rotating the shaft relative to the front tube of the base. [0017] The front wheel device includes at least one front wheel rotatably attached to the front portion of the base with a pivot rod, and coupled to the shaft with a link. The shaft includes a bar secured thereto and extended forwardly from the shaft, for coupling to the link. [0018] The rotating device includes a platform rotatably attached to the base, and device for coupling the platform to the shaft. The coupling device includes a connector coupled between the platform to the shaft. [0019] Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
