COMBINATION OF TREADMILL AND STAIR CLIMBING MACHINE
First Claim
1. A combination of treadmill and stair climbing machine, comprising:
- a frame;
a roller rotatably supported by the frame;
a first pedal and a second pedal, each pedal pivotally connected with the frame and including a belt positioned about the roller;
an interconnection mechanism operably connecting the first pedal and the second pedal such that pivotal movement of the first pedal in a first direction is coordinated with pivotal movement of the second pedal in a second direction opposite the first direction;
a switch member pivotally connected with the frame, the switch member configured to be pivoted to a first position wherein the first and second pedals are locked in a fixed orientation relative to the frame;
a sub-frame is connected to a side plate connected with frame;
a handle having a cam head pivotably connected to a pin which extends through the sub-frame and a first hole defined through the plate, a spring mounted on the pin and biased between the side plate and the sub-frame, the switch member having an extension which has a second hole defined therethrough, the pin being inserted in the second hole when the switch member is set in the first position.

Abstract
A combination of treadmill and stair climbing machine includes a single roller supported on a shaft between two lugs on two sides of the frame of the combination and two rear ends of two pedals are respectively connected to the roller and supported on the two lugs. Two front ends of the two pedals are respectively connected to two hydraulic cylinders. A switch member is pivotably connected to a front end of the frame and can be set in a horizontal position when the combination is used as stair climbing machine, and an inclined position when the combination is used as treadmill. An L-shaped plate is connected to the frame and each pedal has a connection plate which has two elongate holes in which two protrusions on each side of the L-shaped plate are movably engaged, such that the pedals are pivotably supported on the L-shaped plate when used as stair climbing machine.
