Pedal lifting mechanism for elliptical trainer

Abstract

A pedal lifting mechanism for use in an elliptical trainer includes a base, a lift bracket pivotally connected with the base for supporting pedals of the elliptical trainer thereon, and an inclination adjusting device mounted in front of the lift bracket. When a driver of the inclination adjusting device is actuated, a driving rod of the inclination adjusting device is changed in its length by the driver, such that a frame of the inclination adjusting device, which is pivotally connected between the driving rod and the lift bracket, is driven by the driving rod to move the lift bracket upwards and downwards relative to the base. Thus, the inclination angle of each of two pedals of the elliptical trainer is adjusted to change the paths of the pedals of the elliptical trainer.

Description

BACKGROUND OF THE INVENTION [0001]1. Field of the Invention[0002]The present invention relates to elliptical trainers and more particularly, to a pedal lifting mechanism for an elliptical trainer.[0003]2. Description of the Related Art[0004]An elliptical trainer is a well-developed cardio-respiratory fitness exercise machine for shuffling the feet back and forth within the elliptically shaped paths to simulate walking, running, or stair climbing for achieving the purpose of exercising leg and thigh muscles. However, the conventional elliptical trainer has a monotonous operation because the pedals are moved along fixed paths, such that the conventional elliptical trainer can only be used to exercise the specific parts of the leg and thigh muscles.[0005]Taiwan Patent No. I294294 discloses an elliptical trainer, comprising two pedals, a guide track bracket, and an inclination adjusting device. The inclination adjusting device includes a screw rod, a nut member screwingly coupled to the...

AI Technical Summary

Benefits of technology

The present invention provides a simple and easy-to-assemble pedal lifting mechanism for an elliptical trainer that is low in manufacturing cost. The mechanism includes a base, a lift bracket, an inclination adjusting device, a driving rod, and a frame. The driving rod is connected to the driver and can be adjusted in length to bias the lift bracket upwards and downwards relative to the base. This allows the paths of two pedals to be changed to exercise different parts of the leg and thigh muscles. The frame includes a main rod, a shaft, and two rollers for structural stability. The technical effect of the present invention is to provide an affordable yet effective tool for muscle training.

Problems solved by technology

However, the conventional elliptical trainer has a monotonous operation because the pedals are moved along fixed paths, such that the conventional elliptical trainer can only be used to exercise the specific parts of the leg and thigh muscles.

According to the aforesaid prior arts, the inclination adjusting device or the lift device is difficult to be assembled within a limited space, and therefore this problem may lead to a complicated structure and high manufacturing cost.
