Abstract

A hand driving cycle exerciser includes a base having a front wheel device and a rear fork to support a rear wheel with an axle. Two rotary members are rotatably attached onto the rear wheel with unidirectional bearings, two followers are 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 are rotatably attached to the base and connected to the followers, to unidirectionally rotate the rear wheel via the followers and the rotary members and the unidirectional bearings with the handles.

Description

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 comprisin...
