Benefits of technology

[0010] The primary objective of the present invention is to provide a foldable treadmill including a structure for allowing the treadmill to be easily folded to an upwardly erecting or folding position and to be easily folded to a downwardly horizontal working position.

Problems solved by technology

However, the treadmill frame includes a long integral structure that the motorized lifting structure has to spend more or great energy to rotate or to fold the treadmill frame relative to the carriage.
In addition, when the treadmill frame is rotated or folded relative to the carriage, the center of gravity of the treadmill will be offset from the carriage such that the treadmill will be unstable and may have a good chance to fall down.
However, similarly, the tread base also includes a long integral structure that the power driving device also have to spend more or great energy to rotate or to fold the tread base relative to the seat.
In addition, when the tread base is rotated or folded relative to the seat, the center of gravity of the treadmill will be offset from the seat such that the treadmill will be unstable and may have a good chance to fall down.

Embodiment Construction

[0027] Referring to the drawings, and initially to FIGS. 1 and 2, a foldable treadmill 1 in accordance with the present invention comprises a seat 10 including one or more, such as two ears 11 extended upwardly from the front portion 12 of the seat 10, and including two side tubes 13, and a rear link 14 coupled or secured between the rear portions of the side tubes 13, in which each of the side tubes 13 includes a bore 15 formed therein, and a channel 16 is formed in the inner portion of each of the side tubes 13 and communicating with the bore 15 of the respective side tubes 13 (FIG. 1).

[0028] A bolt or threaded member 20 is rotatably disposed or supported or engaged in the middle portion of the seat 10 and disposed between the side tubes 13 and parallel to the side tubes 13, and a motor 21 is also attached to the seat 10 and coupled to the threaded member 20 with various typical coupling mechanisms (not shown), such as pulley-and-belt, sprocket-and-chain, gear coupling, or other ...

Abstract

A foldable treadmill includes a seat, and a two-part tread base having a front carriage pivotally attached to the seat with a pivot axle for allowing the carriage to be rotated relative to the seat, and a rear treadmill frame pivotally secured to the carriage for allowing the treadmill frame to be rotated and folded relative to the carriage, and the carriage is foldable and engageable with the seat for lowering a center of gravity of the treadmill and for preventing the treadmill from falling down when the treadmill frame is rotated and folded relative to the carriage and the seat. A spring biased latch may selectively latch the treadmill frame to the carriage at an upwardly erecting position.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a foldable treadmill, and more particularly to a foldable treadmill having an improved structure for allowing the treadmill to be easily folded to an upwardly erecting or folding position and to be easily folded to a downwardly horizontal working position. [0003] 2. Description of the Prior Art [0004] Typical foldable treadmills comprise a handle device extended upwardly from a seat or vertically supported on the seat, and a tread base having a front portion pivotally attached to the seat or the handle device for allowing the tread base to be rotated or folded relative to the seat or the handle device between an upwardly erecting or folding position and a downwardly horizontal working position. [0005] For example, U.S. Pat. No. 6,015,368 to Clem et al. discloses one of the typical foldable treadmills also comprising a treadmill frame having a front portion pivotally or rotatably atta...
