Integrated folding mechanism of a treadmill

Abstract

An integrated folding mechanism of a treadmill having a slide pusher supported by a pneumatic cylinder at the bottom of a platform frame thereof. In this way, the rear support may be pushed upward to bring the platform frame in a vertical stable folding position or in a flat ground-touching position when the platform frame is moved upward and downward. Meanwhile, a coupling rod is pivotally interposed between the rear support and an L-shaped handrail assembly. Under the action of an elastic element, the handrail assembly is movable with the platform frame for creating a synchronic folding and extending action.

Description

BACKGROUND OF THE INVENTION[0001]1. Fields of the Invention[0002]The invention relates to an integrated folding mechanism of a treadmill, and more particularly, to a folding mechanism that provides an excellent auxiliary and supporting force when the platform frame is moved upward in a folded position and downward in a flat position. Meanwhile, a handrail assembly is movable to create a synchronic folding and extending action.[0003]2. Description of the Related Art[0004]As well-known, the treadmill has a large volume and a great weight. It is therefore common to provide the platform frame of the treadmill with a fold-up function for facilitating the transportation and the storage. In view of the basic accessories of the treadmill, the fold-up mechanism can be divided into an electric and a manual folding configuration. The invention is intended for the manual folding configuration.[0005]In fact, the conventional treadmills are not able to provide an excellent auxiliary supporting fo...

AI Technical Summary

Benefits of technology

[0007]It is a primary object of the invention to eliminate the above-mentioned drawbacks and to provide a folding mechanism of a treadmill that employs a pneumatic cylinder and a slide pusher to provide an effective auxiliary and supporting force when the platform frame is moved in a vertical position or in a horizontal position. Meanwhile, by use of a rear support, a coupling rod, and an elastic element, the handrail assembly is movable with the platform frame to create a synchronic folding and extending action.

Problems solved by technology

In fact, the conventional treadmills are not able to provide an excellent auxiliary supporting force for helping the operator to complete the fold-up or fold-down process when the platform frame is moved either in a storage position or in an operation position.

Thus, the women often regard the fold-up or fold-down process of the treadmill as an impossible mission because any careless action would cause injuries to the body.

The worry about the above-mentioned operation of the treadmill can be attributed to the improper or insufficient design of the treadmill in addition to the bulky platform frame.
