Dual-function treading exerciser

Abstract

A dual-function exercise device includes lower body exercise device, a frame, and a movable handle assembly. The movable handle assembly includes two independent pulling devices and a rotary shaft journalled on the frame. Each pulling device includes a pulley disposed rotatably on the frame, a pull cord wound on the pulley, a handgrip fastened to an end of the cord and movable to unwind the cord from the pulley, and a biasing unit for biasing the cord to wind around the pulley when the cord is pulled and is subsequently released.

Description

FIELD AND BACKGROUND OF THE INVENTION [0001] The invention relates to a dual-function exerciser that exercises muscles and muscle groups in both the upper and lower body. [0002] A conventional treading exerciser includes a treading platform, a continuous tread that extends around the platform, an upright frame that extends upwardly from a front end of the platform, a control panel mounted on a top portion of the upright frame, and a pair of fixed handles disposed on opposite sides of the control panel. [0003] Some treading exercises include upper body exercise components that attempt to simulate various activities such as running, cross-country skiing, and others. These prior devices have numerous disadvantages that fail to exercise the muscle groups of the chest and abdomen or do so in an unnatural movement. Other devices are impractical to manufacture or difficult to maintain. SUMMARY OF THE INVENTION [0004] Therefore, the main object of the present invention is to provide a dual-...

AI Technical Summary

Benefits of technology

[0004] Therefore, the main object of the present invention is to provide a dual-function exerciser that can provide exercise function for the whole body of the user, that can train the user's arm, chest, back, abdominal, and leg muscles, and that can improve functioning of the user's cardiopulmonary system. The exerciser includes independently operated movable handle units that provide a variety of arm movements to simulate different activities.

[0005] According to the present invention, a dual-function exerciser can include a treading platform, an upright frame, and a movable handle assembly. The treading platform has a front end, and is provided with a continuous tread extending around the platform. The upright frame includes an upright frame body connected to the front end of the platform, and an optional pair of fixed handles connected to an upper portion of the frame body. The movable handle assembly includes a pair of pulling devices mounted on the frame, and a rotary shaft journalled on the frame. Each of the pulling devices includes a housing with a receiving chamber, a pulley disposed rotatably in the chamber, a pull cord wound on the pulley, a handgrip fastened to an end of the pull cord and movable rearwardly to unwind the pull cord from the pulley, and a biasing unit for biasing the pull cord to wind around the pulley when the cord is pulled rearwardly and is subsequently released. This device permits the user's arms to move independently from one another and in a more natural motion.

Problems solved by technology

These prior devices have numerous disadvantages that fail to exercise the muscle groups of the chest and abdomen or do so in an unnatural movement.

Other devices are impractical to manufacture or difficult to maintain.
