DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1 to 3, an exercising device in accordance with the present invention comprises a frame (10), a seat (15), two pedals (16), a housing (30) and an exercising mechanism (20). The frame (10) has a supporting stand (13) with two ends, a front leg (11) and a rear leg (12). The front leg (11) and the rear leg (12) are attached respectively to the ends of the supporting stand (13). In a preferred embodiment, the front leg (11) has a height shorter than that of the rear leg (12) to make the supporting stand (13) inclined relative to a horizontal level. In addition, the frame (10) further comprises a bottom stand (14) securely attached to the front leg (11).

The seat (15) is attached to the supporting stand (13) to support a user on the frame (10). In a preferred embodiment, the seat (15) is slidably mounted on the supporting stand (13) and has a bore (151). The supporting stand (13) has multiple holes (131) arranged in a line and selectively aligning with the bore (151) in the seat (15). A pin (155) extends through the bore (151) in the seat (15) and into one of the holes (131) in the supporting stand (13) to hold the seat (15) in position relative to the supporting stand (13).

The pedals (16) are pivotally attached to the bottom stand (14) to connect to the front leg (11) through the bottom stand (14).

The housing (30) is connected to the front leg (11).

With further reference to FIG. 4, the exercising mechanism (20) is mounted inside the housing (30) and on the bottom stand (14). The exercising mechanism (20) comprises a base (21), two brackets (22), a rotating axle (23), a torsion spring (24), a flywheel (25), a resistant device, a pulling rope (29), an adjusting button (28) and a first grip (291). The base (21) is securely attached to the bottom stand (14) to connect to the front leg (11) through the bottom stand (14). The brackets (22) are mounted on the base (22). The rotating axle (23) is rotatably mounted between the brackets (22). The torsion spring (24) is attached to one of the ends of the rotating axle (23) to provide a recoil force to the rotating axle (23). The flywheel (25) is rotatably attached to the rotating axle (23) in a unidirectional manner. In a preferred embodiment, a unidirectional bearing (252) is mounted between the rotating axle (23) and the flywheel (25) such that the flywheel (25) rotates relative to the rotating axle (23) when the rotating axle (23) rotates in a specific direction and rotate with the rotating axle (23) when the rotating axle (23) rotates in a reverse direction.

The resistance device is mounted between the base (21) and the flywheel (25) to provide a resistance to the flywheel (25). In a first embodiment, the resistance device comprises a resistance belt (26) and a resilient member (262). The resistance belt (26) is mounted around the flywheel (25) and has a first end securely attached to the base (21) and a second end. The resilient member (262) preferably is a spring and has a first end attached to the second end of the resistance belt (26) and a second end. With the resistance belt (26) mounted around the flywheel (25), the resistance belt (26) can provide a resistance to the rotation of the flywheel (25) with the friction between the resistance belt (26) and the flywheel (25).

The adjusting button (28) is rotatably attached to the housing (30) and connected to the resistance device with a cable (271). In the first embodiment, the cable (271) is connected to the second end of the resilient member (262). When the adjusting button (28) is rotated, the resilient member (262) will be pulled or released so that the friction between the resistant belt (26) and the flywheel (25) is changed. Accordingly, the resistance applied to the flywheel (25) and provided by the resistance device can be adjusted by means of rotating the adjusting button (28).

The pulling rope (29) has a first end reeling around the rotating axle (23) and a second end extending out of the housing (30). The first grip (291) is attached to the second end of the pulling rope (29).

Furthermore, the bottom stand (14) has a through hole (145) and a notch (143) communicating with the through hole (145). The front leg (11) has a through hole (112) and a notch (114) communicating with the through hole (112) in the front leg (11). As shown in FIGS. 1 and 8, a resilient rope (40) is attached to the through hole (145) in the bottom stand (14) and has a distal end. A second grip (42) is attached to the distal end of the resilient rope (40). In another embodiment, the resilient rope (40) is attached to the through hole (112) in the front leg (11). In use, with reference to FIGS. 1 and 6, the pin (155) is detached from the bore (151) in the seat (15) to make the seat (15) slidable along the supporting stand (13). The user sits on the seat (15), holds the first grip (291) by hand and steps on the pedals (16). Then, the user can pull the pulling rope (29) to release it from the rotating axle (23) and to extend out from the housing (30). At this time, the rotating axle (23) will be driven to rotate, and the flywheel (25) will rotate with the rotating axle (23) and the torsion spring (24) will be twisted tightly. During the rotation of the flywheel (25), the resistance belt (26) will provide a resistance force to the flywheel (25) against the pulling force provided by the user, such that a training effect to muscles on the arms and legs of the user is achieved.

When the user releases the force applied to the pulling rope (29), the pulling rope (29) will reel onto the rotating axle (23) automatically with the recoil force provided by the torsion spring (24). With the arrangement of the unidirectional bearing (252), the flywheel (25) will not rotate with the rotating axle (23) while the pulling rope (23) reels onto the rotating axle (23) to make the rotating axle (23) rotate in a low friction condition. During the operation of the exercising device, the seat (15) can slide along the supporting stand (13) with the movement of the body of the user.

With reference to FIGS. 1 and 7, the seat (15) can be securely held on the supporting stand (13) in place with the pin (155) being inserted into the bore (151) in the seat (15) and one of the holes (131) in the supporting stand (13). The user sits on the seat (15), holds the first grip (291) by hand, steps on the pedals (16) and pulls the pulling rope (29). Because the seat (15) is positioned on the supporting stand (13), to pull the pulling rope (29) out of the housing (30) not only needs the muscles on the arms, but also needs the muscles on the abdomen. Therefore, a training effect to muscles on the arms and abdomen of the user is simultaneously achieved.

With reference to FIGS. 1, 2 and 8, the user can stand on the pedals (16) and holds the second grip (42) by hand to pull the resilient rope (40), such that the muscles on the arms of the user can be trained in a different way. Accordingly, muscles of different parts of the user can be trained with the exercising device, and the exercising device in accordance with the present invention is versatile in use. In addition, the exercising mechanism (20) has an elementary structure, so the structure of the exercising device is simplified whereby the cost for manufacturing the exercising device is low.

With reference to FIGS. 1 and 5, the second embodiment of the resistant device comprises a metal collar (25A), a magnetic resistance element (26A) and a resilient member (262A). The metal collar (25A) is attached to an outer periphery of the flywheel (25). The magnetic resistance element (26A) is pivotally attached to the base (21) and corresponds to the metal collar (25A) on the flywheel (25). One end of the magnetic resistance element (26A) is connected to the cable (271). The resilient member (262A) is mounted between the base (21) and the magnetic resistance element (26A). The magnetic resistance element (26A) will provide an attractive force to the metal collar (25A) on the flywheel (25), such that a resistance force will be provided to the flywheel (25) during the rotation of the flywheel (25).

When the adjusting button (28) is rotated, the magnetic resistance element (26A) will be pulled far away from the metal collar (25A) or pushed near the metal collar (25A) by the resilient force provided by the resilient member (262A). Consequently, the attractive force applied to metal collar (25A) will be changed, and resistance applied to the flywheel (25) is also adjusted.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
