Description

Technical field

[0001] The present utility model relates to the field of fitness equipment, in particular a force exchange system. State of the art

[0002] Currently, conventional cable crossover training mechanisms generally use a weight selection system with pins to adjust the resistance. The user selects the desired training weight by inserting a pin into the corresponding holes in the weight stack.

[0003] Although US patent US8465400B1 describes a technical solution that allows a cable crossover training mechanism to achieve various force variations, this is always accomplished by adding steel cables and joining them at the output end to change the force. This makes the steel cable system complex and difficult to install and operate. Therefore, there is an urgent need for a technical solution to address the problem of adjusting the output force of the weight mass of the cable crossover training mechanism. Content of the utility model

[0004] The present utility model offers a force exchange system to solve the existing problems, comprising a steel cable and a weight device, wherein the steel cable is connected at one end to the weight device, the other end of which provides an output load for training, and at least one device for switching the steel cable is arranged at one end of the weight device.

[0005] The present utility model, by means of the device for switching the steel cable, changes the conventional method of force change, which previously could only achieve an increase in weight by joining steel cables together, and adds a more convenient solution for force change at the weight source, in addition to the direct operation of the weight stack.

[0006] Furthermore, the weight device is the weight stack of a cable crossover training mechanism, wherein the steel cable comprises the load cable and the output cable, and the device for switching the steel cable is arranged at the output end of the weight stack.

[0007] The steel cable serves as a support for load transfer and comprises two steel cable sections: one section that is connected to the weight stack, and the other section that is responsible for delivering the force.

[0008] Furthermore, the device for switching the steel cable comprises an adjustment frame, wherein the adjustment frame is rigidly connected to the frame of the cable crossover training mechanism on the side adjacent to the weight stack, the guide rod is rigidly connected to the adjustment frame in the vertical direction, the pulley assembly frame is arranged along the guide rod, the adjustment frame has a switch, the load cable is connected to the weight stack at one end, and its other end is passed through the upper pulley of the pulley assembly frame and connected to the stop column.

[0009] The switch on the adjustment frame is responsible for connecting and disconnecting the adjustment frame and the stop column.

[0010] Furthermore, the switch can also be located at both ends of the stop column.

[0011] Once the switch is positioned on the stop column, the switch is responsible for connecting and disconnecting the adjustment frame and the stop column, which represents an alternative method for implementing the connection and disconnection.

[0012] The implementation of the device for switching the steel cable is not limited to the type described in the present utility model; its core principle is that switching between single-cable and double-cable modes can be achieved after the steel cable has passed through a pulley. When the switch on the adjustment frame is closed, the stop column is rigidly connected to the adjustment frame. At this point, the load cable is in double-cable mode and can deliver a force equivalent to the weight of the load device. When the switch on the adjustment frame is open, the stop column separates from the adjustment frame and connects to the stop slot. At this point, the steel cable is in single-cable mode and delivers a force equivalent to half the weight of the load device.

[0013] Furthermore, the switch comprises a rotating shaft and hook assembly. This assembly, which passes through the adjustment frame, is rigidly connected to a hook located on both sides of the adjustment frame.

[0014] The shape of the switch is varied; the type described here is merely one type of switch that implements the single and double rope switching of the load rope by means of a hook shape.

[0015] The roller assembly has a stop slot at its upper end. The stop column is operatively connected to the stop slot. The hook is operatively connected to the stop column. When the hook is open, the stop column and the stop slot are connected. When the hook is closed, the hook is connected to the stop column.

[0016] The present utility model represents only one embodiment in which the single and double rope switching of the steel rope is achieved by connecting and disconnecting the hook, the stop column and the stop slot; solutions for single and double rope switching of the steel rope that are readily apparent to a person skilled in the art in this field all fall within the conceptual scope of the present utility model.

[0017] The roller assembly frame has at least one deflection roller.

[0018] The core operating principle of this utility model is as follows: After the load cable is connected to the weight stack, the steel cable is switched between single-cable and double-cable modes using the switching device. In single-cable mode, the output cable delivers half the force; in double-cable mode, the output cable delivers full force. The structure of this utility model, alone or in combination with other pulley and sheave combinations, can achieve force output ratios of 1:1 / 4, 1:1 / 3, 1:2 / 3, 1:1 / 2, 1:1, and 1:2, thus providing a wider adjustment range for the output force of the weight mass in cable crossover training mechanisms with a fixed weight stack.

[0019] In one embodiment, the roller assembly frame has two deflection rollers (one upper and one lower) for switching between full force and half force. The sequence of events for the device switching the steel cable is as follows: 1 / 1 Force: In the initial state, the rotating shaft and hook assembly drives the hook as it rotates, engaging the lifting column and switching the load rope to double-rope mode. The output rope passes through the lower pulley of the pulley assembly and corresponds to 1 / 1 of the weight of the weight stack, i.e., a 1 / 1 force is delivered. Half force: When the rotating shaft and hook assembly rotates in the opposite direction, it drives the hook to release the stop column. The stop column engages in the stop slot of the track roller assembly. At this moment, the load rope switches to single-rope mode. The output rope passes through the lower track roller of the track roller assembly and is half the weight of the weight stack, meaning half the force is applied.

[0020] The advantageous effects of the present utility model are: 1. The force exchange system overcomes the problems of conventional steel cable weight devices, which are cumbersome in force change and complex in construction, and offers a completely new way of force change and a force exchange system for steel cable weight devices. 2. The force exchange system is located on the side near the weight device, which can significantly increase the adaptability of the steel cable system and add more training positions. 3. The force exchange system solves the problem of force change at the weight source and offers more force ratios for training. 4. The possibility of changing the force exchange system at the weight source also provides basic structural support for optimizing and improving the overall layout of the fitness equipment.

At the output end of the weight stack 9, the steel cable switching device is arranged, the steel cable switching device comprising the adjustment frame 2. The adjustment frame 2 is rigidly connected to the frame on the side adjacent to the weight stack. The guide rod 8 is rigidly connected to the adjustment frame 2 in the vertical direction. The pulley assembly 5 is arranged along the guide rod 8. On one side of the adjustment frame 2, the pivot shaft and hook assembly 1 is arranged, which passes through the adjustment frame 2.
