## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an exercise device, and in particular to an exercise device comprising a wheel type treadmill and a display or other simulation apparatus to provide a wide variety of interactive exercise options.
2. Description of the Related Art
Exercise devices of various types are well known and popular. However, exercise is often repetitive and boring, especially when performed indoors. One widely used exercise device is a treadmill, comprising a belt 13′ driven by roller shafts 15a′, 15b′, as shown in FIG. 1. Settings such as speed are input from a panel 100′ and a handrail 11′ is held during use. Front and back roller shafts 15a′, 15b′ either actively drive the belt 13′ as the user 10′ runs or walks thereon, or, in passive mode, freely rotate, driven by user tread activity producing friction on belt 13′.
Even so, the device provides only a very limited range of exercise experience, and thus, little motivation or interest to the user.
SUMMARY OF THE INVENTION
Thus, an object of the invention is to provide an exercise device, provided with a display or other simulation apparatus, offering the user a simulated environment for both mental and physical interactivity and providing climbing experience to make exercise routines fresh and motivating.
The present invention provides an exercise device, including a wheel type treadmill, a roller shaft, a sensor, a panel, a processing unit, and a display. The wheel type treadmill has a plurality of footplates disposed on a wheel. The roller shaft is coupled to the wheel. The sensor is disposed on the treadmill, connecting with the roller shaft. The panel is coupled to the treadmill for setting operation modes. The processing unit is disposed in the panel to receive signals from the sensor and control the operation modes. The display is coupled to the panel, receiving video information from the processing unit and displaying environmental simulation.
A detailed description is given in the following embodiments with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 2A is a schematic view of an exercise device E1 with an upright wheel type treadmill 13 according to the present invention. The user holds the handrail 51 and steps on footplates 53a and 53b, disposed between two sides 57, to experience climbing motion. The left and right footplates 53a, 53b are coupled to rotatable wheel 55. The wheel 55 rotates about a shaft 59, disposed on the side 57. The shaft 59 is coupled with a sensor 56 converting activity to signals received by the processing unit 200 to control the display 30 or personal display device 40 (as shown in FIG. 3A) such that climbing, walking or running speed controls the displayed simulation. A panel 100 is disposed in front of the treadmill 13, providing different operation settings such as speed and active or passive mode selection. In passive mode, the user 10 can climb at any desired speed, controlling the speed of the treadmill 13. In passive mode, a predetermined speed is set, and followed by the user 10.
The footplates 53 of the treadmill 13 are kept in a useable horizontal orientation by built-in counter-weighting. Other means can be implemented to maintain the footplates in a horizontal orientation, as is apparent to those skilled in the art, thus, further explanation is not described here.
FIG. 2B is a flowchart showing steps for operating the exercise device with an environmental simulation display device 30. In this case, the environmental simulation display device 30 is a type of display unit to show simulated videos during use, and the environmental simulation display device 30 is coupled to the panel 100. The environmental simulation display device 30 can be a panel type, disposed in front of the treadmill 13. The panel 100 has a processing unit 200 and an input device 202. When the processing unit 200 receives a command from the input device 202, a signal is sent to a controller 204 located at the base of the treadmill 13. The controller 204 controls the treadmill 13. Thus, combining the treadmill 13 and the environmental simulation display device 30 provides a variety of exercising environments.
Furthermore, FIG. 3A is a schematic view showing an exercise device E2 with a personal display device 40 according to the second embodiment. In this case, the personal display device 40 has a display unit 41 disposed thereon to provide environmental simulation.
FIG. 3B is a flowchart showing steps for operating the exercise device E2 with the personal display device 40 according to the second embodiment of the invention. The panel 100 has a processing unit 200 and an input device 202. When the processing unit 200 receives a command from the input device 202, a signal is sent to a controller 204 located at the base of the treadmill 13. The controller 204 controls the treadmill 13. Thus, combining the treadmill 13 and the personal display device 40 offers the user 10 a simulated environment for both mental and physical interactivity and providing climbing experiences to make exercise routines fresh and motivating.
When the user 10 uses the treadmill 13 with the personal display device 40 thereon, the displayed simulation corresponds to the level of activity on the exercise device.
While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
