1. Fields of the Invention
The invention relates to a resistance apparatus of a pendulum mechanism of an exercise equipment, and more particularly, to a structure for providing a proper exercise resistance.
2. Description of the Related Art
Previously, the applicant of the invention has disclosed a new pendulum type coupling mechanism for certain exercise apparatuses (such as waist-twisting exerciser, an elliptical cross trainer, etc.) having different kinds of the reciprocating movement to replace the inertia flywheel type structure for meeting the exercise requirement of the operators in a better way and for effectively avoiding the exercise injuries. The patent of the above-mentioned structure is still pending (see U.S. patent application Ser. No. 12/177,150) so that no further descriptions thereto are given hereinafter. The invention is an extended structure relative to the pendulum type coupling mechanism previously developed.
A first object of the invention is to provide a resistance apparatus of a pendulum mechanism of an exercise equipment wherein a resistance adjuster having a telescopic rod is pivotally coupled between the pendulum of the pendulum mechanism and the base frame for providing a proper exercise resistance. In this way, the exercise effect is enhanced.
According to the invention, the resistance apparatus includes a resistance adjuster interposed between the pendulum and the base frame. The resistance adjuster includes an adjustable pneumatic cylinder or an adjustable hydraulic cylinder for providing a proper exercise resistance when the pendulum swings by the action of a force.
The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
The present invention will now be described in more detail hereinafter with reference to the accompanying drawings that show various embodiments of the invention.
As shown in
The resistance adjuster 20 includes an adjustable pneumatic cylinder or an adjustable hydraulic cylinder.
Likewise, as shown in
Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
