Description

FIELD OF THE INVENTION

The present invention relates to an exerciser, and more particularly, to a treadmill with weights pulled by a cable so that the users lift the weights while using the treadmill.

BACKGROUND OF THE INVENTION

A conventional exerciser such as a treadmill generally includes an endless belt which is driven by a motor and the users run on the moving endless belt. Another exerciser includes a plurality of weights and an end of a cable is connected the weights and the other end of the cable is connected with a handle. The users pull the handle downward to lift the weights to exerciser the muscles. However, the two types of exercises have to be purchased individually and they occupy a lot of space. Although some multiple-function exercisers provide several different functions in one exerciser, not any exerciser in the market provides a combination function of treadmill and weight training exerciser.

The present invention intends to provide an exerciser which is a combination of a treadmill and a weight training exerciser, the users can lift and maintain the weights at a desired height while running on the endless belt.

A frame is connected to the base and two guide rods are connected to the frame. A plurality of weights are movably mounted on the two guide rods and a cable unit has a cable which has a first end fixed to an end member on the weights and a second end of the cable reeve through several pulleys respectively connected on the frame, the base and an adjusting unit which is connected to the base, and the second end of the cable is connected to a connection member which is connected to the user's body.

The primary object of the present invention is to provide an exerciser that includes a cable unit connected with weights so that the users lift the weights whole running on the endless belt.

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the exercisers of the present invention comprises a base 1 having a running board 2 connected thereto and an endless belt 21 is connected to the running board 2. The endless belt 21 is driven by a motor 22 which is located at a first end of the base 1. Two posts 11 are connected on two sides of the base 1 and a control unit 12 is connected on the two posts 11. The motor 22 for driving the endless belt 21 is electrically connected to the control unit 12 so that the user can control the speed of the endless belt 21. A frame 3 is connected to the first end of the base 1 and includes a top portion 31, a lower portion 32 and a connection portion 33 which is connected between the top portion 31 and the lower portion 32. Two guide rods 4 are connected to the frame 3 and a plurality of weights 41 are movably mounted on the two guide rods 4. An adjusting unit 6 is connected to a second end of the base 1.

A cable unit 5 includes an end member 51 connected to the weights 41 and a cable 53 has a first end fixed to the end member 51. A second end of the cable 53 reeves through a first pulley 52 on the top portion 31 of the frame 3, a second pulley 521 on the lower portion 32, a third pulley 522 on the second end of the base 1 and a fourth pulley 62 on the adjusting unit 6. A connection member 54 is connected to the second end of the cable 53 and the connection member 54 is in a form of a belt which is attached to the user's body. The adjusting unit 6 includes a link 61 which has one end pivotably connected to an end plate 23 of the base 1 and the other end of the link 61 is connected to the fourth pulley 62. A resilient member 63 is connected between the link 61 and the base 1 so as to pulls the link 61 and the fourth pulley 62 back to their original positions as shown in FIG. 2 when not in use.

As shown in FIG. 3, the user runs on the endless belt 21 and the connection member 54 is attached to the user's body so that the user lifts a pre-set number of weights 41 while running on the endless belt 21 to have two different types of exercise functions. As shown in FIG. 4, the exerciser of the present invention may also be a foldable exerciser so as to be stored in a smaller space.

FIG. 5 shows a second embodiment of the exerciser of the present invention, wherein the frame 3A is connected to a second end of the base 1 and includes a top portion 31A, a lower portion 32A and a connection portion 33A which is connected between the top portion 31A and the lower portion 32A. The adjusting unit 6A is connected to the second end of the base 1 and located between the top portion 31A and the lower portion 32A. The adjusting unit 6A includes an adjusting post 64A and a guide pulley 65A. The adjusting post 64A is connected between the top portion 31A and the lower portion 32A. A plurality of positioning holes 641A are defined in the adjusting post 64A and the guide pulley 65A is connected to one of the positioning holes 641A by a positioning member 66A. The top portion 31A has the first pulley 52A and the second end of the cable 53A reeves through the first pulley 52A and the guide pulley 65A and is connected to the connection member 54A.

The position of the guide pulley 65A is easily adjusted so as to meet requirements of users of different heights.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
