Pedal motion path adjustable elliptical trainer

Abstract

A pedal motion path adjustable elliptical trainer includes a base frame , a support mechanism including a rail holder pivoted to the base frame, a support member and two sliding rails, a rotating mechanism set mounted at the left and right sides of the base frame and movable along a respective closed-loop motion path with a respective support link thereof respectively slidably coupled to one respective sliding rail, a linkage mechanism set mounted at the left and right sides of the base frame, and a sliding mechanism mounted at the rail holder and including a transmission member, two follower members respectively mounted on two opposite ends of the transmission member and movable relative to each other. Thus, the elliptical trainer allows the user to change forward-backward pedal motion paths or left-right pedal motion paths, achieving training of different groups of the muscles of the legs.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to elliptical machines and more particularly, to a pedal motion path adjustable elliptical trainer, which allows change of pedal motion paths.[0003]2. Description of the Related Art[0004]Elliptical trainer is a stationary exercise machine used to simulate walking that move along a smooth, elliptical path. Elliptical trainers offer a non-impact cardiovascular workout that can help you reach your health and fitness goals. The pedal motion paths of conventional elliptical trainers are constant, hence, the entire exercise will seem tedious, and will be unable to train all different muscles of the legs.[0005]Taiwan Patent 1294294 discloses an elliptical trainer entitled “LEG-TRAINING ELLIPTICAL MACHINE”, which uses a screw rod of a slope control mechanism to control movement of a female screw member, causing the female screw member to bias a drag bar. When biasing the drag bar, the angle of a ra...

AI Technical Summary

Benefits of technology

The present invention provides a pedal motion path adjustable elliptical trainer that allows quick adjustment of forward-backward and left-right pedal motion paths. This allows training of different groups of muscles of the legs. The elliptical trainer has a sliding mechanism and a support mechanism that allows for lateral and vertical displacement, enabling the user to change the left-right or front-back pedal motion paths for training different muscle groups.

Problems solved by technology

The pedal motion paths of conventional elliptical trainers are constant, hence, the entire exercise will seem tedious, and will be unable to train all different muscles of the legs.

Thus, only a small part of the muscles of the legs can be trained during exercise, resulting in poor effects of exercise.

If the user wishes to change the outward expansion angle, the user must purchase a different model of elliptical trainer or a different type of sliding rails, causing so much inconvenience.
