Abstract
A stepping exerciser includes a pair of foot pedals each having a bent segment disposed on one end and bent relative to the foot pedals and pivotally secured to the base with a pivot shaft, for allowing the foot pedals to be moved up and down relative to the base. The foot pedals each includes a longitudinal axis offset from the pivot shaft, or an included angle is formed between the foot pedals and the bent segments, for increasing the lateral movement of the foot pedals when the foot pedals are moved up and down relative to the base.
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 having an increased lateral movement.




2. Description of the Prior Art




Typical stepping exercisers are shown in FIG.


5


and comprise a base


10


, and a pair of foot pedals


12


having a front end pivotally secured to the base


10


with a pivot shaft


11


, for allowing the foot pedals


12


to be moved up and down relative to the base


10


. One or more resilient band or the other hydraulic or pneumatic cylinders


16


may further be provided and attached to the foot pedals


12


for applying a resistive force against the foot pedals


12


. However, when the foot pedals


12


are rotated relative to the base


10


about the pivot shaft


11


, the lateral movement “d” of the foot pedals is relatively small, such that the users are almost moved up and down relative to the base


10


only, and may not move forward and upward and downward and rearward, and such that the stepping exercisers may not be used for simulating the actual ladder climbing action or the real stepping exercises.




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 an increased lateral movement.




In accordance with one aspect of the invention, there is provided a stepping exerciser comprising a base including a first end having a pivot shaft provided therein, a pair of foot pedals including a first end having a bent segment provided thereon and bent and inclined relative to the foot pedals respectively, the bent segments each including a first end located close to the foot pedals respectively, and each including a second end pivotally secured to the base with the pivot shaft, for allowing the foot pedals to be moved up and down relative to the base. The foot pedals each includes a longitudinal axis offset from the pivot shaft, for increasing a lateral movement of the foot pedals when the foot pedals are moved up and down relative to the base.




A resistive device may further be provided for applying a resistive force against the foot pedals.




The bent segments each includes a longitudinal axis, the longitudinal axes of the foot pedals and the bent segments respectively include an included angle formed therebetween.




Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to the drawings, and initially to

FIGS. 1 and 2

, a stepping exerciser in accordance with the present invention comprises a base


10


including a front portion having a shaft


11


provided therein, such as laterally provided therein. A pair of foot pedals


12


include a front portion pivotally or rotatably secured to the base


10


with the pivot shaft


11


, for allowing the foot pedals


12


to be moved up and down relative to the base


10


. One or more resilient belts or actuators


16


may further be provided and coupled to either or both of the foot pedals


12


, for applying a resistive force against the foot pedals


12


.




The foot pedals


12


each includes a bent segment


14


bent or inclined relative to the foot pedals


12


respectively, and provided on the front portion thereof. The bent segment


14


includes a first end formed integral to or secured to the foot pedal


12


or located close to the foot pedal


12


, and a second end pivotally secured to the pivot shaft


11


, such that the plane or the longitudinal axis


20


of the foot pedal


12


is offset from the pivot shaft


11


, best shown in FIG.


2


. The bent segment


14


also includes a plane or a longitudinal axis


30


, and an included angle “a” will be formed between the longitudinal axes


20


,


30


of the foot pedal


12


and the bent segment


14


.




In operation, as shown in

FIG. 3

, when the foot pedals


12


are moved or rotated up and down relative to the base


10


about the pivot shaft


11


, the foot pedals


12


may include a lateral movement “D” greater than the lateral movement “d” of that of the typical stepping exercisers (FIG.


5


). When stepping or exercising on the stepping exerciser as shown in

FIGS. 1-3

, the feet of the users may move relatively upward and forward when the foot pedal


12


is moved or rotated upward, and may move relatively downward and rearward when the foot pedal


12


is moved or rotated downward.




It is to be noted that the offset of the plane or the longitudinal axis


20


of the foot pedal


12


from the pivot shaft


11


may increase the lateral movement of the foot pedals


12


relative to the base


10


, when the foot pedals


12


move up and down relative to the base


10


. Or, the bent segments


14


of the foot pedals


12


may be rotated or moved forward and rearward relative to the pivot shaft


11


, best shown in

FIGS. 2-3

, for increasing the lateral movement of the foot pedals


12


relative to the base


10


, when the foot pedals


12


move up and down relative to the base


10


.




Referring next to

FIG. 4

, the included angle “a” between the longitudinal axes


20


,


30


of the foot pedal


12


and the bent segment


14


may be arranged or formed smaller or greater. The requirement or the limitation of the included angle “a” is provided or arranged for allowing the foot pedals


12


to be moved up and down in order to conduct the stepping exercises. For example, the included angle “a” between the longitudinal axes


20


,


30


of the foot pedal


12


and the bent segment


14


may be arranged or formed less than 30 degrees or greater than 150 degrees, provided that the foot pedals


12


may be moved up and down relative to the base


10


in order to conduct the stepping exercises by the users.




The base


10


may further include a post


15


extended upward therefrom, such as extended upward from the front and middle portion thereof, and preferably located between the foot pedals


12


. A rod


17


may further be provided and rotatably secured to the base


10


, or secured to the post


15


. A lever


18


is secured to the rod


17


, and includes two ends located below and engaged with the bottom of the foot pedals


12


, for supporting the foot pedals


12


, and for coupling or connecting the foot pedals


12


together. Two cushions or pads


19


are further provided and attached onto the ends of the lever


18


, for resiliently or safely engaging with the bottom of the foot pedals


12


.




In operation, when one of the foot pedals


12


is depressed downward by the users, the other foot pedal


12


will be forced and actuated to move upward by the lever


18


. On the contrary, when the other foot pedal


12


is depressed downward by the users, the one foot pedal


12


will be forced and actuated to move upward by the lever


18


.




Accordingly, the stepping exerciser in accordance with the present invention includes an increased lateral movement.




Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
