Fitness treadmill

Abstract

A fitness treadmill consists mainly of a base, two sliding rail sets and two stepping boards; each of the rail set is formed by two rails in symmetrical shape; each rail has an upper rail strip assembled on the lower rail strip and the upper and lower rail strips are implemented with one or more than one guiding section based on the stepping board moving method; whereas the two stepping boards are respectively installed with front rollers and rear rollers on the two sides for each of the stepping board set to be assembled to each sliding rail set so that the rear rollers are pressed against the upper rail strip and the front rollers are pressed against the lower rail strip for the front and rear rollers to roll along the upper and lower rails and guiding section.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention is related to a fitness treadmill, particularly a fitness treadmill structure design with special dual rail and stepping board structure.[0003](b) Description of the Prior Art[0004]The structural features of conventional treadmill is to install two pieces of movable stepping boards on the machine, allowing user to perform exercises similar to running and jogging while avoiding the vibration caused by impinge and resulting in burden to joints. However, there are several ways to drive the direction, height, or angle of the stepping boards. Some install weight distribution wheel at chosen place, and linking cranks are installed on both sides of the weight distribution wheel. The stepping boards are then connected to the cranks and hence could cause feet exercise alternatively. Others install a bobbing rod on both sides of the erecting pole of the machine. The stepping boards are respectively pivoted ...

AI Technical Summary

Benefits of technology

[0006]The purpose of the present invention is to provide a fitness treadmill that makes use the upper rail, lower rail, and stepping board assembled to the upper and lower rails design so as to allow stepping board perform to and fro rail with action similar to running in order to achieve the result of really exercising both feet as well as avoiding the sport injury of knee burden. And with the upper and lower rails design it is possible to alter the shape of the rails as desired to achieve different exercise result.

[0008]The other purpose of the present invention is to provide a fitness treadmill design that could install two rocking rods on the treadmill. The two said rocking rods are long rods that are pivoted at selected places on the lateral bar between the two handrails. A pulling strip is installed at the bottom of each rocking rod so that one end of the pulling strip is pivoted to the rocking rod and the other end is pivoted to the stepping board. In other words, the two rocking rods and the two stepping boards are jointly connected so that when the hands are holding the rocking rods the effect of swinging both arms while running can be achieved.

Problems solved by technology

The stepping boards are then connected to the cranks and hence could cause feet exercise alternatively.

Their common problem is in that user cannot perform running exercise, particularly the sing curved rail and the swinging exercise structures that can only allow user to swing the leg.

The muscles on the feet and legs could not exert force and therefore hard to achieve the effect of real exercise.

Whereas the treadmill installed with weight distribution wheel has complicated structure that is not only difficult to store away but also costs dearly.
