Stepping exercise machine

Abstract

A stepping exercise machine includes a base and a pedal. The base is provided with an undulating slide rail. A top end of the slide rail is defined as a peak. Bottom ends of two sides of the peak are defined as troughs. The two sides of the peak or the bottom ends of the troughs are provided with stop blocks, respectively. An underside of the pedal is pivotally connected with rollers. Two sides of the underside of the pedal are fixedly connected with a pair of stretchable elastic members. The other ends of the pair of stretchable elastic members are fixed to two sides of the base. The rollers support and drive the pedal to reciprocate along the undulating slide rail ups and downs by means of the stretchable elastic members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

(6) Referring to FIG. 1 to FIG. 6, the present invention discloses a stepping exercise machine. The stepping exercise machine includes a base 10 and a pedal 20 which can be slid left and right as well as ups and downs on the base 10. The base 10 is provided with an undulating slide rail 11. The highest point of the slide rail 11 is defined as a peak 11a. The bottoms of two ends of the peak 11a are defined as troughs 11b, respectively. The troughs 11b are disposed uphill relative to the peak 11a. The highest point of the undulating slide rail 11 is defined as the peak 11a, and the lowest point of the bottom ends of two sides of the undulating slide rail 11 is defined as the trough 11b. Each of the troughs 11b is provided with a stop block 12. The pedal 20 may be one-piece or composed of left and right pedals, but not limited thereto. Two sides of the underside of the pedal 20 are pivotally connected with rollers 21. The rollers 21 support and drive the pedal 20 to slide along the undulating slide rails 11 back and forth as well as ups and downs. Two sides of the slide rail 11 are undulated symmetrically. Two sides of the peak 11a at the highest point of the slide rail 11 are provided with stop blocks 12 respectively, so that the roller 21 at one side of the slide rail 11 won't slide to the other side of the slide rail 11 to limit the moving range. The pedal 20 takes the peak 11a of the slide rail 11 as the highest point to image a symmetrical line. Therefore, the two sides of the slide rail 11 are disposed symmetrically, and the rollers 21 are also disposed symmetrically.

(7) A pair of stretchable elastic members 30 is symmetrically disposed at the two sides of the undulating slide rail 11. The pair of stretchable elastic members 30 includes a left stretchable elastic member 31 and a right stretchable elastic member 32 which are symmetrically disposed at the two sides of the slide rail 11. The base 10 is formed with a pair of holes 13 corresponding in position to the middles of the two sides of the slid rail 11. The holes 13 are symmetrically connected with the left stretchable elastic member 31 and the right stretchable elastic member 32. Lower ends of the left stretchable elastic member 31 and the right stretchable elastic member 32 are inserted through the holes 13 and fixed to the bottom of the base 10 through positioning pins 13a, respectively. Upper ends of the left stretchable elastic member 31 and the right stretchable elastic member 32 are symmetrically connected to the two sides of the underside of the pedal 20. Furthermore, an elastic cord 33 may be provided in each stretchable elastic member 30 for assisting in displacement. Further, the pair of stretchable elastic member 30 may include more than one pair of stretchable elastic members 30 symmetrically disposed between the two sides of the underside of the pedal 20 and the base 10 for adjusting the tensile resistance.

(8) The rollers 21 support and drive the pedal 20 to slide along the undulating slide rail 11 back and forth as well as ups and downs by means of the stretchable elastic members 30. When the pedal 20 is undulated, the wave curvature is formed along the two ends of the slide rail 11.

(9) As shown in FIG. 1, when the stepping exercise machine is not in use, the left and right stretchable elastic members 31, 32 don't generate a tensile force so that the pedal 20 is restrained on top of the peak 11a of the slide rail 11. When in use, as shown in FIG. 5 and FIG. 6, the user can slide left by pedaling the pedal 20, and the right stretchable elastic member 32 is forcedly stretched to increase the pedal strength of the user. The pedal 20 applied with a force by the user's feet drives the left roller 21 to move down along the left side of the slide rail 11 to the left trough 11b, and the right roller 21 of the pedal 20 is moved up along the right side of slide rail 11 from the right trough 11b. After that, when the pedal 20 is slid right, the left stretchable elastic member 13 is forcedly stretched to increase the pedal strength of the user. The pedal 20 is reciprocated left and right and ups and downs to achieve a full-body workout.

(10) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
