BACKGROUND OF THE INVENTION [0001]1. Field of the Invention [0002]The present invention relates to a stepping exerciser, and more particularly to a stepping exerciser including inclined pivot axles to tiltedly support foot pedals and to allow the foot pedals to be moved upwardly and forwardly to simulate the true ladder climbing exercises. [0003]2. Description of the Prior Art [0004]Typical stepping exercisers comprise a pair of foot pedals to be stepped downwardly and alternatively by users, in order to train the lower muscle groups of the users. Normally, the front portions of the foot pedals are rotatably or pivotally attached to a straight and lateral axle, for allowing the foot pedals to be moved upwardly and downwardly. [0005]In most of the typical stepping exercisers, such as U.S. Pat. No. 6,315,697 to Chen, a pair of foot pedals are also disclosed and are also arranged to be stepped downwardly and alternatively by users. However, in the typical stepping exercisers, the foot pedals may only be moved downwardly and upwardly relative to the supporting base but may not be moved forwardly and rearwardly relative to the supporting base, such that the typical stepping exercisers may not be operated to simulate the true ladder climbing exercises. [0006]U.S. Pat. No. 6,595,899 to Liang discloses another typical stepping exerciser comprising a pair of foot pedals each pivotally or rotatably attached to a U-shaped seat with pair of rocking arms, and arranged to be stepped downwardly and laterally by users. However, similarly, in these typical stepping exercisers, the foot pedals may only be moved downwardly and laterally or sidewise relative to the supporting base but may not be moved forwardly and rearwardly relative to the supporting base, such that the typical stepping exercisers also may not be operated to simulate the true ladder climbing exercises. [0007]U.S. Pat. No. 5,665,033 to Palmer discloses a further typical stepping exerciser comprising a pair of foot pedals pivotally or rotatably attached to a pair of inclined pivot axles, and arranged to be stepped downwardly and alternatively by users. However, similarly, in these typical stepping exercisers, the foot pedals also may only be moved downwardly and laterally or sidewise relative to the supporting base but may not be moved forwardly and rearwardly relative to the supporting base, such that the typical stepping exercisers also may not be operated to simulate the true ladder climbing exercises. [0008]The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional stepping exercisers. SUMMARY OF THE INVENTION [0009]The primary objective of the present invention is to provide a stepping exerciser including an inclined pivot axle to tiltedly support foot pedals and to allow the foot pedals to be moved upwardly and forwardly to simulate the true ladder climbing exercises. [0010]In accordance with one aspect of the invention, there is provided a stepping exerciser comprising a base including an inclined pivot axle extended rearwardly and upwardly therefrom and perpendicular to an inclined plane inclined relative to the base, a pivotal supporting device attached to the inclined pivot axle of the base and movable in a plane parallel to the inclined plane, and two foot pedals pivotally attached to the pivotal supporting device and arranged to allow the foot pedals to be stepped downwardly by a user, and the foot pedals are movable downwardly and rearwardly and upwardly and forwardly when the foot pedals are stepped by the user to simulate the true ladder climbing exercises. [0011]The pivotal supporting device includes an arm having a middle portion pivotally attached to the inclined pivot axle of the base and having two end portions pivotally coupled to the foot pedals respectively. [0012]The foot pedals each pivotally attach to the end portions of the arm with a pivot shaft, and each includes two bars of different lengths extended therefrom and pivotally attached to the pivot shafts respectively for horizontally supporting the foot pedals which are parallel to the base and thus for stably supporting the users on the foot pedals. [0013]The pivotal supporting device includes two links pivotally coupled between the foot pedals and the base for forming a parallelogrammic structure and for stably supporting the foot pedals to the arm. [0014]A resistive device may further be provided and disposed between the foot pedals or the pivotal supporting device and the base, to provide a resistive force against the foot pedals. The resistive device may be coupled to the arm. [0015]The pivotal supporting device includes a fastening plate attached to the base and engaged with the arm and the resistive device to stably retain or position the arm and the resistive device to the base. [0016]The base includes a post extended upwardly and forwardly therefrom along the inclined plane, the pivot axle is extended upwardly and rearwardly from the post. [0017]Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
