Treadmill

Treadmill description/claims

1. Field of Invention

The present invention relates to a treadmill and, more particularly, to a miniature, structurally simple and therefore inexpensive treadmill.

2. Related Prior Art

Recently, time and places for exercise are getting less. Therefore, there have been devised various exercise machines for providing various training programs such as bicycles and treadmills.

There has been a conventional treadmill that only allows a user to move his legs up and down alternately with limited effects of exercise.

There has been another conventional treadmill that allows a user to move his legs up and down and back and forth alternately; however, it is bulky, structurally complicated and therefore expensive. It is inconvenient for the user to install, use and store the bulky oval-trace exercise machine.

To improve the effects of exercise, there has been devised another conventional treadmill including a base, a wheel disposed on a front portion of the base and two exercise units arranged on opposite sides of the wheel. Each exercise unit includes a track, a keel and a tread. The tread is carried on the keel. The keel includes a front end connected to the wheel and a rear end movably mounted on the track. This conventional treadmill is still bulky.

Disclosed in Taiwanese Patent M271597 is a treadmill including a base 10, a shaft 20 disposed on a front portion of the base 10, a wheel 16 disposed on a lower portion of the base 10 and two exercise units. Each exercise unit includes a rocker 23 connected to the shaft 20, a crank 161 connected to the wheel 16, a keel 25 arranged between the rocker 23 and the crank 161 and a tread 26 disposed on the keel 25. This conventional treadmill however forces the user to take small steps instead of strides for using a very small wheel.

The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.

The primary objective of the present invention is to provide a miniature, structurally simple and therefore inexpensive treadmill.

According to the present invention, a treadmill includes a frame, two tracks, a wheel, two keels and two treads. The frame includes a front portion and a rear portion. The tracks are extended from the rear portion of the frame. The wheel is provided on the front portion of the frame. Each of the keels includes a front end connected to the wheel and a rear end movable on a related one of the tracks. Each of the treads is carried on a related one of the keels.

Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.

The present invention will be described through detailed illustration of two embodiments referring to the drawings wherein:

FIG. 1 is a perspective view of a treadmill according to the first embodiment of the present invention;

FIG. 2 is a side view of the treadmill shown in FIG. 1;

FIG. 3 is a partial exploded view of the treadmill shown in FIG. 4;
