1. Field of the Invention
The present invention relates to a stationary exercise device, and more particularly to an elliptical and stationary exercise device including a braking device for resisting or retarding the movement or the actuation or the operation of the stationary exercise device, and for allowing the exercise device to be safely actuated or worked by the user.
2. Description of the Prior Art
Typical stationary exercise devices, such as stepping exercisers comprise a pair of handles pivotally attached to an upwardly extending frame member of a base support device, and a pair of foot supports pivotally coupled to the handles and arranged for allowing the foot supports to be stepped or moved up and down relative to the base support device. The applicant has also developed various kinds of elliptical exercisers or stepping exercisers for being stepped or actuated or worked or operated by the user to train the lower muscle groups.
For example, U.S. Pat. No. 7,485,072 to Chuang et al., U.S. Pat. No. 7,608,018 to Chuang et al., and U.S. Pat. No. 7,811,206 to Chuang et al. disclose several of the typical exercise devices each comprising a pair of handles pivotally attached to an upwardly extending frame member of a base support device, and a pair of foot supports pivotally coupled to the handles, and a pair of force resisting device pivotally coupling the foot supports to the upwardly extending frame member for allowing the foot supports to be stepped or actuated or moved up and down relative to the base support device.
Normally, one or more pulleys or idle wheels are pivotally or rotatably attached to the base support device and coupled to the handles or the foot supports for applying a resisting or retarding force to the handles or the foot supports.
However, the typical exercise devices have no braking devices provided for resisting or retarding the striding or stepping movement or the actuation or the operation of the stationary exercise device, and the exercise device may not be safely actuated or worked by the user.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional elliptical or stationary exercise devices.
