Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a stepping exerciser, and more particularly to a stepping exerciser including a simplified support for supporting the stepping exerciser.




2. Description of the Prior Art




Various kinds of typical stepping exercisers have been developed and used today, and include a pair of pivotal foot pedals attached to a base for allowing the foot pedals to be actuated or stepped and exercised by the users. One or more actuators or pneumatic or hydraulic cylinders are provided for coupling to the foot pedals and for applying the resistive force against the foot pedals. However, a complicated coupling device is required for coupling the actuators or the cylinders together, or for coupling the foot pedals for allowing the stepping operations of the exercisers to be connected together.




The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional stepping exercisers.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a stepping exerciser including a simplified support for supporting and coupling the stepping operations of the foot pedals.




The other objective of the present invention is to provide a stepping exerciser including a simplified counter device for counting the stepping operations of the users.

A device may further be provided for counting rotations of the shaft relative to the post. The lever and the shaft includes a simplified structure and may be rotatable relative to the post when the foot pedals are moved up and down relative to the base.




The counting means includes a first actuator member disposed in the post, and a second actuator member attached to the inner end of the shaft, and located close to the first actuator member, and movable across the first actuator member when the shaft is rotated relative to the post.




The counting means includes a processor device coupled to the first actuator member for detecting a relative movement between the first actuator member and the second actuator member, and thus for counting the movement between the actuator members.




The second actuator member is a magnetic member and attached to the inner end of the shaft. The shaft includes a stud provided on the inner end thereof for supporting the magnetic member.




The counting means includes a casing secured on the post, the first actuator member is secured to the casing. The casing includes a conduit extended therefrom the first actuator member is engaged in the conduit.

10


, about the pivot axle


14


as that of the typical stepping exercisers.




A shaft


16


is rotatably secured to the post


11


, and preferably parallel to the foot pedals


12


when the foot pedals


12


are not being actuated and are located side by side, best shown in

FIGS. 3 and 4

. The shaft


16


includes one end engaged into the post.


11


, and is preferably perpendicular to the post


11


, but may be slightly inclined relative to the post


11


and the base


10


, as also shown in

FIG. 3. A

lever


17


is secured to the other end or the outer end of the shaft


16


and preferably perpendicular to the shaft


16


, and includes two ends each having a cushion or a pad


18


secured thereon for engaging with the bottom surfaces of the foot pedals


12


respectively, and for allowing the foot pedals


12


to be coupled together.




For example, as shown in

FIGS. 3-6

, when one of the foot pedals


12


is forced or stepped downward, the other foot pedal


12


may be caused to move upward by the lever


17


; and vice versa, such that the foot pedals


12


may be actuated or operated or used to conduct the stepping exercises. One or more actuators


19


(

FIGS. 1

,


3


) may further be provided and coupled to the foot pedals


12


respectively, for applying a resistive force against the foot pedals


12


. As shown in
