ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an exerciser, and more particularly to an exerciser for conducting pushing and pulling simulating exercises.
2. Description of the Prior Art
Typical pushing and pulling exercisers comprise a wheel rotatably engaged on a rod or a handle. The user may hold the handle and may move the handle forward and rearward with the wheel. However, no spring biasing members may be used for recovering the exerciser.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional pushing and pulling exercisers.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a pushing and pulling simulating exerciser including a spring biasing member for recovering the exerciser.
In accordance with one aspect of the invention, there is provided an exerciser comprising a frame, a rod engaged through the frame, the rod including two ends, a first wheel rotatably engaged on the rod and including at least one first hole formed therein, and a resilient belt received in the rod and including two ends retained to the ends of the rod, the resilient belt including a middle portion engaged through the first hole of the first wheel. The belt may be wound around the rod when the first wheel is rotated relative to the rod.
The frame includes at least one second wheel secured thereon for facilitating moving of the frame. The frame further includes at least one pulley rotatably secured thereon for winding the belt therearound. The frame further includes at least one casing formed thereon for rotatably receiving the pulley.
Two stops are further secured to the ends of the belt and engaged with the ends of the rod for retaining the ends of the belt to the ends of the rod. The first wheel includes at least one second hole formed therein for selectively threading the belt.
Two pulleys are further rotatably engaged on the rod for winding the belt therearound. The pulleys each includes a hole formed therein for threading the belt. The pulleys each includes a peripheral portion having an aperture formed therein and communicating with the hole of the pulley for threading the belt.
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.
