DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Referring firstly to FIG. 1, the exercise stepper of the present invention is comprised of a bottom rack 10, two treadle bars 11, an inclined bar 12, a handle 14, a supporting rod 15 and two oil pressure cylinders 16, wherein: the bottom rack 10 is provided with a front axle shaft 101, a rear bar 102 and an intermediate bar 103 connecting to the middle of the front axle shaft 101 and the rear bar 102. The bottom rack 10 is in the shape of “H”. The connecting area of the front axle shaft 101 with the intermediate bar 103 has a protruding cushion block 104. The rear bar 102 is provided on each end thereof with a roller 105; and a connecting spot of the rear bar 102 with the intermediate bar 103 forms a connecting area 106 for connecting the inclined bar 12; the inclined bar 12 extends frontwardly and upwardly. A neck portion of the inclined bar 12 allows the supporting rod 15 to horizontally extend therethrough. The upper end of the inclined bar 12 is provided with a function display meter 13, a connecting area 121 for connecting the handle 14 is provided on the rear side on the upper end of the inclined bar 12.

[0016] The front ends of the two treadle bars 11 are pivotally connected to a right and a left spot respectively aside of the middle of the front axle shaft 101 which is provided on the two ends thereof each with an annular fixing member 107. The treadle bars 11 are provided on the front sections thereof with connecting areas 111 for connecting with two oil pressure cylinders 16. The rear ends of the treadle bars 11 are extended rearwardly to form treadle pedals 112. The connecting areas 111 for connecting with the two oil pressure cylinders 16 are each pivotally connected to the corresponding bottom end of an oil pressure cylinder 16, the upper ends of the treadle bars 11 are connected with the supporting rod 15 to thereby complete assembling of the present invention.

[0017] When a treadle pedal 112 is trampled down by a user, the other treadle pedal 112 is relatively subjected to a force and is lifted, and vice versa, an effect of sporting thus is formed. The rear bar 102 of the bottom rack 10 of the “H” shape is in the shape of an elliptic bar making the bottom rack 10 stable, the handle 14 can be held by the user; by viewing the function display meter 13, the related sporting information can be known (such as the time of exercising, the amount of calories consumed etc.). The inclined bar 12 is a bar with irregular curvatures, the connecting area 106 for connecting the inclined bar 12 has an inclining angle to thereby be connected with the inclined bar 12 in this inclining angular position, so that the modeling of the entire exercise stepper can be more beautiful, and can meet the requirement of the human body engineering in design. And when in moving, the two ends of the rear bar 102 of the bottom rack 10 are provided each with a roller 105, thereby, it needs only to raise the front axle shaft 101 of the bottom rack 10 to render the rollers 105 to contact the ground, the exercise stepper can be moved to any desired spot at will taking advantage of rolling of the rollers 105.

[0018] When not in use, referring to FIG. 2, the connecting area 106 for connecting the inclined bar 12 is released in the first place, then the inclined bar 12 is directly pressed down to make rotation of the upper and the lower ends of the two oil pressure cylinders 16 (as well as the supporting rod 15 and the connecting areas 111 for connecting with the oil pressure cylinders 16 protruded from the treadle bars 11) therewith. The inclined bar 12 is continuously pressed down till the bottommost. As shown in FIG. 3, by virtue that the inclined bar 12 is a bar with irregular curvatures, it is generally concave on the upper portion and convex on the lower portion thereof, and the front axle shaft 101 of the bottom rack 10 is protrusively provided with the soft protruding cushion block 104, thereby, the inclined bar 12 is not subjected to having the concave upper portion damaged or having the lacquer on the concave upper portion peeled off by collision. The oil pressure cylinders 16 and the two treadle bars 11 are located between the inclined bar 12 and the intermediate bar 103 of the bottom rack 10 to largely reduce the volume of the entire exercise stepper such as is shown in FIG. 4. And more, a connecting area 121 of the handle 14 on the upper end of the inclined bar 12 is further released to allow the handle 14 to rotate reversely and lapped over the oil pressure cylinders 16, as shown in FIGS. 5, 6, in order that when the present invention is not in use, the connecting area 106 for connecting the inclined bar 12, the connecting areas 111 for connecting with the oil pressure cylinders 16 and the connecting area 121 of the handle 14 can be collapsed for storage of the exercise stepper conveniently.

[0019] Accordingly, the structure of the present invention has the following practical advantages:

[0020] 1. The rear bar of the bottom rack is in the shape of an elliptic bar, so that when in use of the present invention, it is not subjected to sliding and provides an effect of stability for the bottom rack; the rear bar further is provided with rollers, no matter the exercise stepper is stretched out or collapsed, it needs only to raise the front axle shaft of the bottom rack to render the rollers to contact the ground, the exercise stepper can be moved conveniently.

[0021] 2. The inclined bar has irregular curvatures, this makes the modeling of the entire exercise stepper more beautiful, and tidy in collapsing without oddity.

[0022] 3. The front axle shaft of the bottom rack is protrusively provided in the middle thereof with the protruding cushion block, thereby, the inclined bar is not subjected to damaging or having the lacquer thereon peeled off by collision due to an overly large pressing-down force.

[0023] 4. By collapsing of the connecting areas, the volume of the exercise stepper can be effectively reduced to not occupy a too large space, thereby the exercise stepper is convenient for storage for a small field.

[0024] In conclusion, according to the content disclosed above, the present invention can get the expected object thereof to provide a practicable exercise stepper.

[0025] The above stated is only for illustrating a preferred embodiment of the present invention and not for giving any limitation to the scope of the present invention. It will be apparent to those skilled in this art that various modifications or changes without departing from the spirit and scope of this invention shall also fall within the scope of the appended claims of this invention.
