Track adjusting mechanism for elliptical exerciser

Track adjusting mechanism for elliptical exerciser description/claims

The present invention relates to a track adjusting mechanism for elliptical exercisers and the track of the pedals can be adjusted by the users.

A conventional elliptical exerciser is shown in FIG. 1 and generally includes a frame 92 on the floor and two rails 921 extend from a rear end of the frame 92. A post extends from the frame 92 and two swinging bars 93 are pivotably connected on two sides of the post. A transmission mechanism 91 includes a wheel 911 connected to the post and each swinging bar 93 is pivotably connected with a first end of a link and a second end of the link is pivotably connected with a movable member 912 which includes a roller 913 movable on the rail 921 corresponding thereto. The user stands on the pedals on the movable members 912 and swings the swinging bars 93 alternatively so that the rollers 913 move on the rails 921 back and forth. The pedals move along an oval trace.

Another conventional elliptical exerciser is shown in FIG. 2 and generally includes a frame 92 on the floor and a post extends from the frame 92. Two swinging bars 93 are pivotably connected on two sides of the post. A transmission mechanism 91 includes a wheel 911 and two movable members 912, wherein the wheel 911 is located on the frame 92 and spins about an axle thereof and the two movable members 912 are pivotably connected between the wheel 911 and the two swinging bars 93. The user stands on the pedals on the movable members 912 and swings the swinging bars 93 alternatively, the pedals move along an oval trace.

Nevertheless, both of the two conventional elliptical exercises can only provide a fixed track for the pedals and the fixed track makes the users feel boring after using a period of time.

The present invention intends to provide a track adjusting mechanism for elliptical exercisers and includes the adjusting mechanism can be pivoted to change the angle between two connection links on which two respective pedals are located. The long axis and the short axis of the oval track can be therefore adjusted.

The present invention relates to an elliptical exerciser that comprises a frame with a wheel connected thereto and two swinging mechanisms are pivotably connected on two sides of the wheel. Each swinging mechanism includes a swing bar and a connection link. A first end of each connection link is pivotably connected to the wheel and a second end of each connection link is connected to an adjusting mechanism which is includes a main body having a first end pivotably connected to the frame and the two second ends of the connection links are pivotably connected to a second end of the main body. A retractable device is connected between the adjusting mechanism and the frame.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

FIG. 1 shows a conventional elliptical exerciser;

FIG. 2 shows another conventional elliptical exerciser;
