The tread belt is supported on a tread deck between a front roller on each treadle assembly, and a rear roller, which may be a distinct rear roller on each treadle assembly or a single rear roller for both treadle assemblies. The monoarm structure of each treadle assembly supports a plurality of deck supports in a cantilever fashion. The treadmill deck and the belt are supported on the deck supports. Further, the treadles are coupled with one or more hydraulic resistance structures, which may also function as an interconnect structure to coordinate pivotal movement of the treadle assemblies.

SUMMARY OF THE INVENTION One aspect of the present invention involves an exercise device including a first monoarm treadle assembly including a first moving surface and a second monoarm treadle assembly including a second moving surface. In one implementation, the moving surface is a tread belt supported on a tread deck between a front roller on each treadle assembly, and a rear roller, which may be a distinct rear roller on each treadle assembly or a single rear roller for both treadle assemblies. The monoarm structure of each treadle assembly supports a plurality of deck supports in a cantilever fashion. The treadmill deck and the belt are supported on the deck supports. Being a monoarm assembly, it is possible to position the tread belt of each treadle assembly in close proximity.
DETAILED DESCRIPTION Referring to FIG. 1, an exercise device 10 conforming to aspects of the present invention may be configured to provide a user with a walking-type exercise, a stepping-type exercise or a climbing-like exercise that is a combination of both walking and stepping. The exercise device generally includes two treadmill-like assemblies (12, 14) (referred to herein as a �treadle� or a �treadle assembly�) pivotally connected with a frame so that the treadles may pivot up and down about a common axis 16 or in the region of a common axis. Each treadle includes a moving surface, such as a belt 18 in a treadmill-like configuration. Generally, the rear of each treadle is pivotally supported on the frame, and the front of each treadle is supported in a way to reciprocate up and down. In use, a user will walk, jog, or run on the treadles and the treadles will pivotally reciprocate about the common axis.
In one implementation, an AC motor is used to power the rollers. With an AC motor, the belt speed may be directly obtained from the AC motor controller. Related U.S. Application No. 60/548,811 titled �Dual Treadmill Exercise Device Having A Single Rear Roller� filed Feb. 26, 2004, which is hereby incorporated by reference herein, and filed on the same day as this application, describes an AC motor and control system that may be employed in one implementation of the present invention. Particularly, a belt speed control unit (�BSCU�) controls the speed of the belts on the treadles based upon belt speed control signals received from a central processing unit (�CPU�).
