Abstract

A position-limiting apparatus of a pendulum mechanism of an exercise equipment, wherein the pendulum of the pendulum mechanism creates an expected coupled swing action responsive to the reciprocating movement done by a certain exercise equipment when subject to the action of a force, thereby providing a proper inertia movement and a gravity load action. A position-limiting apparatus is disposed at a certain position tangential to the swinging path of a pendulum of the pendulum mechanism for an effective restriction of the maximal swing of the pendulum. Moreover, a pneumatic cylinder is provided for creating a proper exercise resistance.

Description

    BACKGROUND OF THE INVENTION
  • 1. Fields of the Invention
  • The invention relates to a position-limiting apparatus of a pendulum mechanism of an exercise equipment, and more particularly, to a mechanism that ensures a effective restriction of the maximal swing of the pendulum. Moreover, a pneumatic cylinder is provided for creating 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.
    • SUMMARY OF THE INVENTION
  • A primary object of the invention is to provide a position-limiting apparatus of a pendulum mechanism of an exercise equipment that provides a position-limiting apparatus disposed at a certain position tangential to the swinging path of a pendulum of the pendulum mechanism for an effective restriction of the maximal swing of the pendulum. Moreover, a pneumatic cylinder is provided for creating a proper exercise resistance that ensures a effective restriction of the maximal swing of the pendulum.
  • According to the invention, the position-limiting apparatus primarily consists of a subsidiary support and two high-strength flexible metal pieces that are mounted at the side of the pendulum of the pendulum mechanism.
  • Furthermore, the pendulum includes a compression roller at a position corresponding to the metal pieces such that the compression roller is gradually in contact with the metal pieces along the direction tangential to the movement path when the pendulum approaches to the swing peak. At that time, the metal pieces are subject to the compression force and therefore gradually deformed, thereby creating a graduate counteracting effect (or a deceleration action on the pendulum) with their own strength. In this way, an effective restriction of the maximal swing of the pendulum is ensured. Thereafter, the resilience of the flexible metal pieces creates a counteracting force acting on the pendulum such that the pendulum swings in the other direction, thereby providing an inertia movement action. In addition, a pneumatic cylinder having a telescopic rod is pivotally coupled between the pendulum and the base frame of the exercise equipment. Moreover, the pneumatic cylinder is provided with air holes for adjusting the amount of the inlet air and the outlet air, thereby creating a proper exercise resistance. In this way, the exercise effect is enhanced.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • 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 FIGS. 1 and 2, a position-limiting apparatus of a pendulum mechanism is applied to a waist-twisting exerciser 10. The waist-twisting exerciser 10 includes a base frame 11, a pair of swivel pedals 12, and a handrail frame 14 with a handle 13. A pendulum mechanism 15 is coupled at the back of the swivel pedals 12. Besides, a position-limiting apparatus 20 is disposed at a certain position tangential to the swinging path of a pendulum 16 of the pendulum mechanism 15 for an effective restriction of the maximal swing of the pendulum 16. The position-limiting apparatus 20 primarily consists of a subsidiary support 21 and two high-strength flexible metal pieces 22 that are mounted at the side of the pendulum 16 of the pendulum mechanism 15. Moreover, the pendulum 16 includes a compression roller 17 at a position corresponding to the metal pieces 22 such that the compression roller 17 is gradually in contact with the metal pieces 22 along the direction tangential to the movement path when the pendulum 16 approaches to the swing peak. At that time, the metal pieces 22 are subject to the compression force and therefore gradually deformed, thereby creating a graduate counteracting effect with their own strength. As a result, an effective restriction of the maximal swing of the pendulum 16 is ensured.
  • Likewise, as shown in FIGS. 3 and 4, a position-limiting apparatus of a pendulum mechanism in accordance with the invention is applied to an elliptical cross trainer 30. The elliptical cross trainer 30 includes a base frame 31, a front ground-touching rod 32, a rear ground-touching rod 33, a front support 35 with two handles 34, two pedal-connecting rods 36, and a pendulum mechanism 38 having two pendulums 37 and coupled with the pedal-connecting rods 36. Similarly, a position-limiting apparatus 40 is disposed at a certain position tangential to the swinging path of two pendulum 37 of the pendulum mechanism 38 for an effective restriction of the maximal swing of the pendulums 37. The position-limiting apparatus 40 primarily consists of a subsidiary support 41 and four high-strength flexible metal pieces 42 that are mounted at the side of the pendulums 37 of the pendulum mechanism 38. Moreover, the pendulums 37 each include two compression rollers 39 at a position corresponding to the metal pieces 42, thereby creating the same expected effect.
  • As shown in FIGS. 5 through 8, a pneumatic cylinder 50 having a telescopic rod 51 is pivotally coupled between the pendulum 16, 37 and the base frame 11, 31 of the exercise equipment (such as waist-twisting exerciser 10 and the elliptical cross trainer 30). Moreover, the pneumatic cylinder 50 is provided with air holes 52 for adjusting the amount of the inlet air and the outlet air, thereby creating a proper exercise resistance. In this way, the exercise effect is enhanced. In other words, a greater exercise resistance is provided when a smaller air hole 52 (having a small air flow rate) is selected.
  • 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.
