Fitness device

Abstract

This invention relates to a fitness device, comprising: a frame and at least one training module. The at least one training module is disposed on the frame and includes a weight, a first steel cable, a second steel cable, a movable pulley system, and a lifting wheel system. The weight is disposed on the movable pulley system. The first steel cable is wound around the movable pulley system and the lifting wheel system. One end of the first steel cable is positioned on the frame, and the other end is a first operating end. One end of the second steel cable is connected to the lifting wheel system, and the other end is a second operating end. The first operating end can be pulled by a user with a first force, thereby moving the weight via the first steel cable, while the lifting wheel system remains stationary. The second operating end can be pulled by a user with a second force, thereby displacing the lifting wheel system via the second steel cable and, in conjunction with the first steel cable, driving the weight to move. The second force is greater than the first force.

Claims

1. A fitness device, comprising: A frame includes a horizontal frame, two side frames, and two movable seats. The two side frames are laterally protruding from the horizontal frame at intervals, thus collectively defining an internal space. The two movable seats are movably positioned on the two side frames. Two training modules are respectively disposed on the frame. Each training module includes a load-bearing body, a first steel cable, a second steel cable, a movable pulley system, and a lifting wheel system. The load-bearing body, the movable pulley system, and the lifting wheel system are disposed on the side frames, and the load-bearing body is disposed on the movable pulley system. The first steel cable is wound around the movable pulley group and the lifting pulley group. One end of the first steel cable is located in the internal space, extending from the bottom of the frame along the side frame and positioned at the movable seat. The other end of the first steel cable is movably passed through the movable seat from the top of the frame along the side frame away from the cross frame to form a first operating end. The first operating end is located outside the internal space. One end of the second steel cable is connected to the lifting pulley group, and the other end of the second steel cable is a second operating end. The first operating end can be pulled by the user with a first force, thereby moving the weight through the first steel cable, while the position of the lifting wheel assembly remains stationary. The second operating end can be pulled by the user with a second force, thereby displacing the lifting wheel assembly through the second steel cable and driving the weight through the first steel cable, whereby the second force is greater than the first force. The fitness device further includes a connector and at least one bearing, the connector being rotatably mounted on the lifting wheel assembly via the at least one bearing, and one end of the second steel cable being connected to the connector. Each training module further includes two track components, one track wheel assembly, and two limiting components. The two track components are located on the frame and limit the lifting wheel assembly, so that the lifting wheel assembly can only move along the two track components. The track wheel assembly is located on the lifting wheel assembly and is movably clamped between the two track components. The two limiting components protrude from the lifting wheel assembly and clamp the two track components on both sides of the track wheel assembly.

2. The fitness device as claimed in claim 1, wherein the frame defines a height direction in which the position of the first operating end is different from the position of the second operating end.

3. The fitness device as claimed in claim 2, wherein the number of the at least one training module is multiple, and the multiple second operating ends are respectively located on opposite sides of the two first operating ends in the height direction.

4. The fitness device as claimed in claim 1, wherein the second operating end is located in the middle region of the crossbeam and within the interior space, and the second steel cable extends from the side frame to the crossbeam.

5. The fitness device as claimed in claim 4, wherein the lifting wheel assembly is located on one side of the side frame near the cross frame, the second steel cable extends from the lifting wheel assembly toward the top of the side frame, and the second steel cable extends from the top of the side frame to the top of the cross frame.

6. The fitness device as claimed in claim 3, wherein the plurality of the second operating ends are coaxially arranged in the height direction; the second operating ends are located in the middle region of the crossbeam and within the internal space; the second steel cable extends from the side frame and the crossbeam; the lifting wheel assembly is located on the side of the side frame near the crossbeam; the second steel cable extends from the lifting wheel assembly toward the top of the side frame, and then from the top of the side frame to the top of the crossbeam; the direction of movement of the lifting wheel assembly is parallel to the direction of movement of the movable pulley assembly; each of the track members is in a straight line. Extended; a plurality of first fixed pulley groups are disposed on the two side frames, and the first steel cable is wound around the plurality of first fixed pulley groups; a plurality of second fixed pulley groups are disposed on the cross frame, and the second steel cable is wound around the plurality of second fixed pulley groups; the second steel cable is suspended from the top of the side frame by the lifting pulley group; viewed along the height direction, the top of the cross frame is shaped like a "U"; each of the track components is a round rod; a first connector is provided at the first operating end, and a second connector is provided at the second operating end; the distance between the two track components is less than the maximum outer diameter of the track pulley group.
