Abstract
A walking machine includes a base, two swivel devices, two footboards movable in sideway directions, a connection transmission device, two recovery transmission devices, and a damping device. The footboards are driven by two feet of an exerciser to actuate the two swivel devices such that two support arms of the swivel devices actuate the two recovery transmission devices, thereby causing two transmission elements of the recovery transmission devices to act on the damping device via the connection transmission device.

FIELD OF THE INVENTION




The present invention relates generally to an exercise machine, and more particularly to a walking machine designed for use in the practice of walking at a steady pace as a form of exercise.




BACKGROUND OF THE INVENTION




The conventional walking machine comprises a left footboard and a right footboard, which are capable of a back-and-forth movement only. In view of lack of variation in motion of the two footboards, the conventional walking machine is prone to failure in sparking interest of an exerciser. In other words, the conventional walking machine is not versatile enough to catch the fancy of the consumer at large.




BRIEF SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a walking machine which is versatile in design so as to satisfy the increasingly demanding consumers.




In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the walking machine comprising two footboards, two swivel devices, two recovery transmission devices, one connection transmission device, and one damping device. The two swivel devices are driven by the two footboards to actuate the two recovery transmission devices, which in turn actuate the damping device via the connection transmission device. The two footboards of the walking machine of the present invention share with the same damping device.




The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




As shown in all drawings provided herewith, a walking machine of the present invention comprises a base


20


, two footboards


30


, two swivel devices


40


, two recovery transmission devices


50


, one connection transmission device


60


, and one damping device


70


.




The base


20


is rested on a surface for supporting other component parts of the walking machine on the surface.




The two footboards


30


are mounted at an interval on the tops of the two swivel devices


40


, which are in turn mounted on the base


20


and are formed of two horizontal pivoting rods


41


, two swivel arms


42


mounted slantingly on the pivoting rods


41


, and a support arm


43


mounted on one of the pivoting rods


41


such that the support arm


43


swivels synchronously with the swivel arms


42


.




The connection transmission device


60


comprises two shafts


61


, two drive wheels


63


mounted on one end of the shafts


61


in conjunction with a one-way bearing


62


, and two engagement gears


64


mounted on the other end of the shafts


61


such that the two engagement gears


64


are engaged with each other. The connection transmission device


60


further comprises a transmission gear


65


, which is mounted on any one of the two shafts


61


and is engaged with a gear set


66


.




The recovery transmission devices


50


comprise a transmission element


51


and a tension element


52


. The transmission element


51


runs on the drive wheel


63


of the connection transmission device


60


such that the transmission element


51


is fastened with the support arm


43


of the swivel device


40


. The tension element


52


is fixed at one end via a steering wheel


21


.




The damping device


70


comprises a belted wheel


71


and a magnetic damping wheel


72


driven by the belted wheel


71


which is linked with the gear set


66


.




In operation, the two footboards


30


are driven by two feet of an exerciser to actuate the two swivel devices


40


such that the two support arms


43


of the two swivel devices


40


actuate the two recovery transmission devices


50


, thereby causing the two transmission elements


51


to act on the damping device


70


via the connection transmission device


60


. In view of the cooperation of the two recovery transmission devices


50


and the connection transmission device


60


, both footboards


30


share with the same damping device


70


.




The walking machine of the present invention may further comprise a handrail frame


22


mounted on the base


20


, and a display.


23


mounted on the handrail frame


22


.




The walking machine of the present invention further comprises a support frame


601


, which is mounted on the base


20


to give an added support to the connection transmission device


60


, with the two drive wheels


63


of the connection transmission device


63


being located in the outside of the support frame


601


.




The footboards


30


of the present invention are optionally provided with an adjustment device


32


which is formed of a threaded rod


34


and an adjustment wheel


35


mounted on the threaded rod


34


. The threaded rod


34


is pivoted with a lug.


33


and a bottom seat


31


of the footboards


30


. The footboards


30


can be tilted by the adjustment wheel


35


, as illustrated in FIG.


10


.




The two footboards


30


of the present invention are movable in sideway directions by virtue of the two swivel devices


40


. In addition, the two footboards


30


share with the same damping device


70


, thereby resulting in decrease in size and cost of the walking machine of the present invention. The present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following claims.
