BACKGROUND OF THE INVENTION

1. Technical Field

The present invention is related to exercise training systems, and more particularly, to an exercise training system providing programmable circulative guiding track (e.g. circular or elliptical guiding track) for an exerciser to move accordingly and detecting the exerciser's performance.

2. Description of Related Art

Taijiquan is known for being beneficial to health and has become a popular exercise nowadays. It's also highly evaluated by general exercisers and sports scientist for its sports effect. Practicing Pushing-hands is one form of Taijiquan training. Through practicing Pushing-hands, the sensitivity, sense of balance, limb coordination and reaction rate can be substantively improved.

In a traditional training method, Pushing-hands is typically practiced through sparring. To practice Pushing-hands, two exercisers face each other and contact the opponent's wrist and make the contacted wrists circling repeatedly in a circular or elliptical guiding track synchronously. During practicing, both the exercisers detect the opponent's motion by his hand, wrist as well as lower arm and give proper reaction. It is important for the exercisers to keep the wrists intercontacting lightly yet avoiding mutual resistance. Thus, Pushing-hands facilitates training for generalized sensitivity, limb coordination and reaction rate. However, one fundamental problem of such traditional training method of Pushing-hands is that the practice requires two participants. Additionally, an exerciser may not get objective data of performance assessment from his opponent as a reference material. Thus the popularization of Pushing-hands is limited.

Some sport facilities have therefore been developed to overcome foresaid limitation in Pushing-hands and benefit the popularization of Taijiquan. However, such prior art facilities are usually noninteractive, unadjustable and nonprogrammable, hence such facilities are inadequate to provide satisfactory training effect.

On the other hand, though Taiwan Patent M064330 provides an interactive Taijiquan simulator whereby an exerciser can practice dodging and parrying, such prior art interactive Taijiquan simulator has no detecting element or means to monitor the exerciser's performance and the guiding track and operating mode thereof are not adjustable. Thus, a need exists for an exercise training system for Pushing-hands practice that provides interactive operating mode and programmable circulative guiding track.

SUMMARY OF THE INVENTION

The present invention has been accomplished under these circumstances in view and discloses an exercise training system for simulating an opponent in Pushing-hands practice to provide different guiding tracks and practicing mode and respond to the exerciser with objective data of performance assessment.

It is one object of the present invention to provide an exercise training system for training an exerciser's sensitivity, sense of balance, limb coordination and reaction rate with Pushing-hands practice.

It is another object of the present invention to provide an exercise training system that allows an exerciser to practice Pushing-hands without the need of a practicing partner.

It is still another object of the present invention to provide an exercise training system that utilizes adjustable linkage system to perform variable guiding track for meeting an exerciser's need and leading effective training of Pushing-hands exercise.

It is yet another object of the present invention to provide an exercise training system that is equipped with sensing elements to detect an exerciser's performance of Pushing-hands for warning the exerciser of the inappropriate exertion or exporting the detecting results as training reference material.

As can be seen in FIGS. 4 and 5, the linkage system is composed of a first link 14, a second link 15, a third link 16 a fourth link 17 and a pivot set 18 wherein each said link is pivotly connected to the adjacent links to form a quadrilateral shape wherein the first link 14 is fastened to the crank 13 with the middle part at a crank joint (g) and is combined with the second link 15 with one end at a first link joint (a); the second link 15 with one end remote from the first link joint (a) connected to the third link 16 at a second link joint (b); the third link 16 with one end remote from the second link joint (b) connected to the fourth link 17 at a third link joint (c); and the fourth link 17 with one end remote from the third link joint (c) connected to the first link 14 at a fourth link joint (d). Further, the fourth link 17 is pivotly fastened to the base frame 10 with the pivot set 18 assembled to the fourth link 17 at a pivot joint (f) located beyond the fourth link joint (d). Thereupon, when the linkage system is operated, a circulative guiding track can be depicted by the extreme of the third link 16 adjacent to the second link joint (b) which is referred to a track point (e) hereinafter.

Additionally, according to the present embodiment, the third link 16 further comprises a frame 162 and an extension arm 161 wherein the frame 162 is pivotly connected to the second link 15 and fourth link 17 respectively at the second link joint (b) and third link joint (c) and the extension arm 161 is slidably installed in the frame 162 and operatively connected to an actuator 163 so that the extension arm 161 can extend or retract with respect to the frame 162 and in turn render the distance between the third link joint (c) and the track point (e) altered, as shown in FIG. 6.

Also, according to the present embodiment, the fourth link 17 is assembled with the pivot set 18 in a slidable way and operatively connected to an actuator 171 which is fixed on the pivot set 18 so that the fourth link 17 can slide against the pivot set 18 to render the distance between the fourth link joint (d) and the pivot joint (f) altered. As shown in FIG. 7, when the fourth link 17 slides against the pivot set 18 under the impetus of the actuator 171, the distance between pairs of links are varied.
