The treadle-connecting rod is provided with a recessed portion in which a pair of shaft tubes are fixed to the center of the recessed portion. The shaft tubes are fitted at both sides with a roller holder, respectively. Two rollers are longitudinally and rotatably connected to the roller holder. The treadle includes a pair of connecting ears near the shaft tubes such that the treadle and the treadle-connecting rod can be movably connected by a pivot, and one end of the metal spring leaves is secured to a fixing base within the connecting ears while the other (free) end thereof is inserted between two rollers such that the metal spring leaves are movable between two rollers when the treadle is subject to an external force.

Description

    BACKGROUND OF THE INVENTION
  • 1. Fields of the Invention
  • The invention relates to a treadle assembly having spring leafs for an exercise apparatus, and more particularly, to a structure that employs metal spring leaves having a stronger resilience to achieve an optimal shock-absorbing and elastic feedback effects, thereby effectively reducing the exercise load.
  • 2. Description of the Related Art
  • U.S. Pat. No. 7,300,387 teaches a “TREADLE ASSEMBLY OF AN EXERCISE EQUIPMENT” in which an elastic restoring body made by rubber filler is provided against the torsion on the treadle. In this way, a cushioning and restoring effect is achieved when a torsion acts on the treadle.
  • However, a long-term service life of the rubber product is not ensured. The rubber product tends to be changed in quality due to the heat produced in the case especially when the repeated torsion force is applied to the rubber product. As a result, the performance is rapidly deteriorated. Moreover, the elastic performance with respect to the loadable torsion force varies with different loads by weight of the operators, thereby resulting in a mixed damping effect evaluation made by the different operators. This is required to be improved.
    • SUMMARY OF THE INVENTION
  • An object of the invention is to provide a treadle assembly having spring leafs for an exercise apparatus that employs metal spring leaves (which is strongly bendable) to enhance the load ability and to ensure the optimal shock-absorbing effect. Moreover, the energy-accumulating metal characteristic is used to provide a reactive force to both feet of the operator, thereby reducing the exercise load and improving the exercise comfort.
  • According to the invention, a treadle-connecting rod of the exercise apparatus is provided with a recessed portion in which a pair of shaft tubes are fixed to the center of the recessed portion. The shaft tubes are fitted at both sides with a roller holder, respectively. Two rollers are longitudinally and rotatably connected to the roller holder. The treadle includes a pair of connecting ears near the shaft tubes such that the treadle and the treadle-connecting rod can be movably connected by a pivot, and one end of the metal spring leaves is secured to a fixing base within the connecting ears while the other (free) end thereof is inserted between two rollers such that the metal spring leaves are movable between two rollers when the treadle is subject to an external force.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
  • FIG. 1 is a perspective view of a preferred embodiment of the invention;
  • FIG. 2 is a side view of the embodiment of the invention according to FIG. 1;
  • FIG. 3 is a side view of the embodiment of the invention according to FIG. 2 after being subject to an external force;
  • FIG. 4 is a side view of the embodiment of the invention applied to an elliptical cross trainer; and
  • FIG. 5 is a side view of the embodiment of the invention applied to an fitness bike.
    •  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.
  • Referring to FIGS. 1 and 2, a treadle assembly having spring leafs for an exercise apparatus in accordance with a preferred embodiment of the invention consists of a treadle 10 and two metal spring leaves 20. The treadle assembly is secured to a treadle-connecting rod 30 of an exercise apparatus (not shown). The treadle-connecting rod 30 is provided with a recessed portion 31 in which a pair of shaft tubes 32 are fixed to the center of the recessed portion 31. The shaft tubes 32 are fitted at both sides with a roller holder 33, respectively. Two rollers 34 are longitudinally and rotatably connected to the roller holder 33. The treadle 10 includes a pair of connecting ears 11 near the shaft tubes 32 such that the treadle 10 and the treadle-connecting rod 30 can be movably connected by a pivot 12. One end of the metal spring leaves 20 is secured to a fixing base 13 within the connecting ears 11 while the other (free) end thereof is inserted between two rollers 34. In this way, the metal spring leaves 20 are movable between two rollers when the treadle 10 is subject to an external force.
  • As shown in FIG. 3, both metal spring leaves 20 are moved in a twisted position when the treadle 10 is subject to an external force. Since the free end of the metal spring leaves 20 can be moved between the rollers 34, the swivel motion of the treadle 10 won't be affected. In removal of the external force, the treadle 10 is able to be returned in its original position.
  • Moreover, the number of the metal spring leaves 20 can be determined in accordance with the preset load and the desirable feedback strength.
  • As shown in FIGS. 4 and 5, the treadle assembly in accordance with the invention is applied to an elliptical cross trainer 40 and a fitness bike 50. It is only required to install the treadle-connecting rod 30 onto the elliptical cross trainer 40 and the fitness bike 50 to achieve the smooth operation and the desired effect of the invention.
  • The elliptical cross trainer 40 and the fitness bike 50 are conventional exercise apparatuses. The connection and the operation of the transmission components belong to the prior art so that no more descriptions thereto are given hereinafter.
  • 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.
