Example

[0015] Referring to FIGS. 1 through 3, a preferred embodiment of the invention includes a frame unit 10 and an electric adjusting mechanism 30.

[0016] The frame unit 10 of the elliptical cross trainer has a bottom support frame 18 at the front end thereof and a flywheel transmission unit at the rear end thereof. The flywheel transmission unit is covered by a protection hood 11 so that it is hidden in the figures. The flywheel transmission unit works in cooperation with two treadle planks 12 on which a treadle 21 is disposed for taking a treading exercise. Two movable handle rods 15 are interposed between two upright posts and pivotally mounted on a first crossbar 14. The bottom of the movable handle rods 15 is pivotally attached to a connecting rod 16. The other end of the connecting rod 16 is pivotally connected to the front section of the treadle plank 12, thereby creating a coupling action. Moreover, the top of the frame unit 10 is provided with a fixed handle rod 17.

Abstract

A pace-adjusting mechanism of an elliptical cross trainer having a U-shaped coupling rod pivotally and laterally disposed on a bottom support frame. An electric adjusting mechanism is interposed between the U-shaped coupling rod and the frame unit. The electric adjusting mechanism includes a motor, a guide spindle sleeve and a telescopic spindle. When the telescopic spindle is driven to be moved, it results in the adjustment of the relative angle of the U-shaped coupling rod, and wherein an L-shaped connecting rod is pivotally coupled to each top side of the U-shaped coupling rod while the end of the L-shaped connecting rod is pivotally attached to a treadle plank so that the vertical position of the treadle planks is adjustable by changing the angle of the U-shaped coupling rod and, therefore, the adjustment of the exercise pace is achieved.

Description

BACKGROUND OF THE INVENTION [0001] 1. Fields of the Invention [0002] The invention relates to a pace-adjusting mechanism of an elliptical cross trainer, and more particularly, to a mechanism that can rapidly adjust the movement pace at will. [0003] 2. Description of the Related Art [0004] The elliptical cross trainer is so used that the operator's feet can make an elliptical movement path, thereby simulating the real running and walking path. Moreover, the horizontal pace (simulating the movement on a flat ground) and the inclined pace (simulating the uphill and downhill movement) can be changed when the vertical position of the treadles of the elliptical cross trainer changes. This is the main intention of the invention. [0005] U.S. Pat. No. 6,090,013 discloses such a mechanism that employs a plurality of selection holes in treadle planks. By selecting a desired hole in the treadle plank for connection, the coupling angle of the treadle plank can be changed to achieve the above-men...
