Exercising machine with adjustable stride length and height

Exercising machine with adjustable stride length and height description/claims

1. Field of the Invention

The invention relates to an exercising machine, more particularly to an elliptical exercising machine.

2. Description of the Related Art

FIG. 1 illustrates a conventional exercising machine that includes a base frame 11, left and right rocker links 131, left and right handles 133, and left and right foot pedals 132. The base frame 11 includes left and right frame members 111. Each of the left and right rocker links 131 is coupled pivotably to a respective one of the left and right frame members 111 of the base frame 11. Each of the left and right handles 133 extends from an upper end portion of a respective one of the left and right rocker links 131. Each of the left and right foot pedals 132 is mounted on a lower end portion of the respective one of the left and right rocker links 131.

The aforementioned conventional exercising machine is disadvantageous in that since the left and right rocker links 131 are disposed between the left and right frame members 111 of the base frame 11, the conventional exercising machine is inevitably large and bulky. Moreover, the conventional exercising machine permits the user (not shown) to perform only one type of a striding movement. That is, the stride length and height of the conventional exercising machine are fixed. As such, the user may get bored of the conventional exercising machine very quickly. Further, each of the left and right rocker links 131 wobbles when the user gets on and off of the left and right foot pedals 132. This poses safety risks in that the user may be lose his or her balance and fall.

Therefore, the main object of the present invention is to provide an exercising machine that can overcome the aforesaid drawbacks of the prior art.

According to the present invention, an exercising machine comprises a base frame, a resistance-imparting rotary member, left and right rocker link units, left and right foot pedals, left and right cross links, and left and right coupling units. The resistance-imparting rotary member is mounted rotatably on the base frame. Each of the left and right rocker link units is coupled pivotably to the base frame and has a plurality of engaging segments disposed along the length thereof. Each of the left and right foot pedals is coupled pivotably to a respective one of the left and right rocker link units. Each of the left and right cross links is coupled pivotably to the rotary member. Each of the left and right coupling units couples pivotably a respective one of the left and right cross links to a selected one of the engaging segments of the respective one of the left and right rocker link units. The length of each of the left and right cross links is adjustable.
