Electric treadmill

Abstract

An electric treadmill includes a base, vertical posts coupled to the base, a desk with a treading belt, and a lifting and folding device. The lifting and folding device includes a linear actuator disposed on the desk and having a retractable lifting pipe, a lifting unit connected to the desk, a pivotal connection point protruding from the desk, first and second lateral panels, and a fixing stand disposed between the second lateral panels and connected to the lifting pipe, two movable pivotal connection elements disposed at free ends of the first lateral panels, respectively, two linking plates connected to the first lateral panels and a link, two position-limiting elements disposed between the base and the lifting unit, connected to two lateral bars of the base by an axle, and having a slot each, and two guide rods coupled to the first lateral panels and inserted into the slots.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to treadmills, and more particularly, to an electric treadmill which has a desk capable of lifting steadily and can be folded easily.[0003]2. Description of Related Art[0004]A conventional electric treadmill in wide use comprises a base, a desk, a power unit, an elevation unit, a stand, and a dashboard disposed on the stand. When the conventional electric treadmill is in use, the desk not only enables a user to walk thereon, but also allow the user to control the dashboard as needed, for example, to adjust the gradient (angular) lift of the desk. An angular lifting and folding structure of the desk operates while the desk is directly connected to the base. As a result, once a lifting unit lifts, an impact and vibrating force will be generated by the user and directly conveyed to the base, and in consequence the dashboard on the stand vibrates. Hence, users always complain about the aforesaid drawb...

AI Technical Summary

Benefits of technology

The present invention provides an electric treadmill with a stable desk and a simple and practical folding mechanism. This results in a highly stable desk and an easy-to-use treadmill folding mechanism.

Problems solved by technology

Hence, users always complain about the aforesaid drawback of the prior art.

Afterward, although Taiwan patent 1234471 improves on U.S. Pat. No. 5,674,453 in terms of the aforesaid drawbacks thereof, its folding structure is flawed with a plethora of constituent elements and a complicated assembly process, and thus it adds to the manufacturing costs to the detriment of commercial competition.
