Foldable elliptical fitness machine

Abstract

A foldable elliptical fitness machine comprises a first frame securely supported on a floor and a second frame for installing an elliptical structure, and the second frame is pivotally coupled to the first frame by a pivoting device, such that the second frame can be rotated with respect to the first frame, wherein the elliptical structure comprises a rotating member having two eccentric pivotal points, and two pedal arms. A central penetrating axle of the rotating member is pivotally coupled onto the second frame, and each eccentric pivotal point is pivotally coupled to the first end of the pedal arm, and each pedal arm includes a footrest for a user to step. If the first end of the pedal arm rotates with the crank, the footrest will move in an elliptic path. With the foregoing structural design, the elliptical structure can be fully folded to improve the convenience of use.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a foldable elliptical fitness machine, and more particularly to an elliptical fitness machine structure that includes a first frame and a second frame, and wherein the second frame installed an elliptical mechanism, and the second frame can be turned and folded upright with respect to the first frame and supported securely by the first frame to achieve the purposes of effectively folding and using the elliptical fitness machine. BACKGROUND OF THE INVENTION [0002] In general, the basic structure of a prior art elliptical fitness machine includes a flywheel, two cranks, and two pedal arms, and a first end of each crank is coaxially connected to the flywheel, and a second end of each crank is pivotally connected to a first end of each corresponding pedal arm, and each pedal arm has a footrest, such that a user can step on the footrest. If the first end of the pedal arm rotates with the crank, the footrest will move in an el...

Benefits of technology

[0004] The primary objective of the present invention is to provide a fully foldable elliptical fitness machine to improve the convenience of its use, and the foldable elliptical fitness machine comprises a first frame and a second frame, wherein the first frame securely supported on a floor and the second frame installed an elliptical structure, and the second frame is pivotally coupled to the first frame by a pivoting device, such that the second frame can be rotated with respect to the first frame, wherein the elliptical structure comprises a rotating member having two eccentric pivotal points, and two pedal arms. A central penetrating axle of the rotating member is pivotally coupled onto the second frame, and each eccentric pivotal point of the rotating member is pivotally coupled to a first end of the corresponding pedal arm, and each pedal arm includes a footrest, such that a user can step on the footrest. If the first end of the pedal arm rotates with the crank, the footrest will move in an elliptic path. With the foregoing structural design, the elliptical structure of the invention has the functions of being fully folded upright and improving the convenience of using the elliptical fitness machine.

Problems solved by technology

If the elliptical fitness machine and the treadmill are placed flatly on a floor for their use, the footprint of these fitness equipments occupy much area.

To reduce the footprint of the fitness machines when the machines are not in use, some treadmills are designed to have a belt that can be folded upward, and it is not easy to design a foldable elliptical fitness machine because many mechanisms are disposed on the link rod, and the elliptical fitness machines are usually designed as a partial foldable structure.

The elliptical exercise machine is partially folded, and the footprint is still large after the machine is folded.

Furthermore, such foldable exercise machine does not come with a function of changing the inclination of the machine, and thus users cannot change the level of difficulty of their exercise by changing the inclination of the elliptical fitness machine.

However, the structure of this machine is not stable enough.
