Folding mechanism for a handrail frame assembly of a treadmill

1. Fields of the Invention

The invention relates to a folding mechanism for a handrail frame assembly of a treadmill, and more particularly, to a folding mechanism through which two handles and a console support at the top end of the handrail frame assembly can be folded in a storage position or moved in an upright position.

2. Description of the Related Art

As well-known, the treadmill has a large volume and a great weight. It is therefore common that the handrail frame assembly is folded toward the platform frame whereupon the platform frame is folded upwards in an upright position for achieving the completely folding effect to facilitate the transportation and the storage. Of course, this structure belongs to basic accessories of a treadmill. Therefore, the invention is aimed to improve the conventional folding mechanism for a handrail frame assembly of a treadmill.

In fact, a console support is often fitted to the top end of the handrail frame assembly for mounting electric control instruments (not shown). Meanwhile, a handle is disposed at each side corresponding to the operator\'s direction for a firm grip of the operator.

However, the console support and the handles at each side trouble the operator to carry out a folding process with more than two steps for solving the problem of space occupied by them after the platform frame is folded up in a storage position. To the contrary, the operator has to perform the reverse complicated process to bring the handrail frame assembly, the console support, and the handle at each side thereof back to their operation position. This process gives the operator much trouble. Thus, the conventional folding mechanism required a further improvement.

It is a primary object of the invention to eliminate the above-mentioned drawbacks and to provide a folding mechanism for a handrail frame assembly of a treadmill that moves with the handrail frame assembly for bringing the handles and the console support toward each other or away from each other in position so as to improvement the convenience in use.

According to the invention, a folding mechanism for a handrail frame assembly of a treadmill includes a coupling cross shaft with a rotational disc at each side thereof for pivotally coupling to the hollow handrail frame assembly. A pull rod is received within the handrail frame assembly. In this way, two handles and a console support at the top end of the handrail frame assembly move by use of the corresponding action of the pull rod toward each other or away from each other in position when the handrail frame assembly is folded in a storage position or moved in an upright position.
