ABSTRACT:
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.
