Description

Technical Field

[0001] This invention relates to a training system, and more particularly to a resistance training system that has two working modes: direct force transmission and force transmission at multiple levels, and can freely switch between the two working modes. Background Technology

[0002] As we all know, physical exercise is the best way to maintain good health, and regular muscle training is the best way to maintain health, shape the body, and promote well-being. To facilitate muscle training, various fitness equipment are now widely used.

[0003] like Figure 1 As shown, resistance trainers are currently the most widely used fitness equipment. The working principle of resistance trainers is as follows: a tension device 2 is set at one end of the traction rope 1. The tension device 2 can be a handle, a lever, a push rod, etc. Correspondingly, a resistance device 3 is set at the other end of the traction rope 1. The resistance device 3 can be a counterweight, a resistance motor, etc. When working, the resistance device 3 generates resistance, which is transmitted to the tension device 2 through the traction rope 1. The tension device 2 acts on the human body to achieve the purpose of training human muscles.

[0004] like Figure 2 As shown, in order to change the direction of resistance transmission and facilitate use, fixed pulleys 4 are often installed in practice to achieve this purpose. Various home strength training equipment utilizes this principle, such as leg press machines and chest press machines. Generally, in public gyms, the resistance device 3 is often a weight plate. However, to reduce weight and floor space, the resistance device 3 in home fitness equipment is often a resistance motor.

[0005] like Figures 2 to 4 As shown, when the resistance device 3 is a resistance motor 31, there are generally two resistance transmission methods. For example... Figure 2 As shown, this is a fixed pulley transmission method. The main advantage of this method is that the force is transmitted directly, and the resistance can be directly transmitted to the tension device 2 through the traction rope 1. Its main disadvantage is that, limited by the maximum output power of the resistance motor 31, this transmission method can only meet the needs of light-weight muscle training, and its applicability is limited. For example, when the resistance motor 31 can only output a maximum resistance of 60 kg, it can only meet the training requirements for weights below 60 kg. To meet the training requirements for heavy weights, the maximum output power of the resistance motor 31 needs to be doubled. However, this would not only significantly increase the cost of the motor but also create some safety hazards.

[0006] like Figure 3 , Figure 4 As shown, under the rated maximum output power of the resistance motor 31, a movable pulley transmission method is used to increase the training weight. The main advantage of this transmission method is that, utilizing the mechanical principles of the movable pulley, the training weight can be doubled under the rated maximum output power of the resistance motor 31. However, its main disadvantage is that it is extremely prone to "rope tangling," which can further lead to safety accidents. The specific reasons for these safety accidents are described below: Strength training is divided into two methods: Method 1 is heavy weight, slow speed training; Method 2 is light weight, fast speed training.

[0007] like Figure 3 As shown, under Method 1, the aforementioned pulley transmission method can generally meet the training requirements. In this case, the output power of the resistance motor 31 is relatively large, and the resistance it generates is also relatively large. Since the large resistance acts on the human body, the human body can only complete the load-bearing task by reducing the speed of movement.

[0008] For example, the resistance motor 31 outputs a resistance of 60 kg. Through the movable pulley 5, the resistance at the position of the pulling device 2 will reach 120 kg. Under this load condition, the human body can only overcome the resistance and complete the load training by moving slowly.

[0009] The traction rope 1 is wound around the rotating output shaft of the resistance motor 31. In mode one, when the human body performs training movements, the resistance motor 31 rotates and slowly releases the traction rope 1. When the human body performs recovery movements, the resistance motor 31 rotates and slowly winds back the traction rope 1.

[0010] In Method 1, the resistance motor 31 can work with the slow movement training of the human body at a low speed, and the speed of the resistance motor 31 can match its action of releasing and retracting the traction rope 1.

[0011] like Figure 4 As shown, however, in the case of method two, the above-mentioned movable pulley transmission method cannot meet the training requirements.

[0012] In the second scenario, the output power of the resistance motor 31 is relatively small, and the resistance it generates is also relatively small. Due to the smaller resistance, the speed of human movement will inevitably increase, and the frequency of reciprocating movement will also inevitably increase.

[0013] For example, the resistance motor 31 outputs 1 kg of resistance. Through the action of the movable pulley 5, the resistance at the position of the pulling device 2 is 2 kg. Under such light load conditions, the human body can easily overcome the resistance to complete the training movement. Therefore, the speed of the human body's movement will inevitably increase, and the frequency of reciprocating movement will also inevitably increase.

[0014] In this situation, the resistance motor 31 needs to rotate twice as fast as in method one to complete the winding and retrieving of the traction rope 1. However, in practice, the performance of the resistance motor 31 often fails to meet the above requirements, which inevitably leads to the resistance motor 31 not "retrieving" the rope in time. Once this happens, the traction rope 1 will inevitably become "slack" or "entangled" at the position of the movable pulley 5, which may lead to a safety accident.

[0015] As mentioned above, these are the main drawbacks of the existing technology. Summary of the Invention

[0016] The technical solution adopted in this invention is as follows: a resistance training system, which includes a body, a resistance motor (20) and a traction rope (30). The traction rope (30) has a winding end (31) and a connecting end (32). The winding end (31) is wound around the rotating output shaft of the resistance motor (20), and the connecting end (32) is movably connected to a converter (100). The converter (100) is connected to a tensioner (40). The resistance motor (20) can generate a tension (F), and the tension (F) is transmitted to the tensioner (40) through the traction rope (30) and the converter (100).

[0017] The converter (100) has two working modes: direct force transmission and multi-level force transmission. In the direct force transmission mode, the converter (100) can directly transmit the force (F) to the tensioner (40). In the multi-level force transmission mode, the converter (100) can convert the force (F) into a multi-level force (Fs) and then transmit the multi-level force (Fs) to the tensioner (40). The converter (100) can switch between the two working modes of direct force transmission and multi-level force transmission.

[0018] A resistance training system includes a body (10), a resistance motor (20), and a traction rope (30). The traction rope (30) has a winding end (31) and a connecting end (32). The winding end (31) is wound around the rotating output shaft of the resistance motor (20), and the connecting end (32) is movably connected to a converter (100). The converter (100) is connected to a tensioner (40). The resistance motor (20) can generate a tension (F), which is transmitted to the tensioner (40) through the traction rope (30) and the converter (100).

[0019] The converter (100) has two working modes: direct force transmission and double force transmission. In the direct force transmission mode, the converter (100) can directly transmit the force (F) to the tensioner (40). In the double force transmission mode, the converter (100) can convert the force (F) into double force (Fa) and then transmit the double force (Fa) to the tensioner (40). The converter (100) can switch between the two working modes of direct force transmission and double force transmission.

[0020] The beneficial effects of the present invention are as follows: The present invention is provided with a converter (100), which has two working modes: direct transmission of tension and multi-level transmission of tension. In the direct transmission of tension mode, the converter (100) can directly transmit the tension (F) generated by the resistance motor (20) to the tensioner (40). In the multi-level transmission of tension mode, the converter (100) can convert the tension (F) generated by the resistance motor (20) into a multi-level tension (Fs), and then transmit the multi-level tension (Fs) to the tensioner (40).

[0021] In addition, the converter (100) can switch between two operating modes: direct force transmission and multiplier force transmission.

[0022] When the present invention operates in the mode of directly transmitting tensile force, it can meet the requirements for training with light weights at high speeds; when the present invention operates in the mode of directly transmitting tensile force, it can meet the requirements for training with heavy weights at slow speeds.

[0048] like Figures 5 to 9 As shown, especially as Figure 5 As shown, a resistance training system includes a body, a resistance motor (20), and a traction rope (30), wherein the resistance motor (20) is fixedly installed in the body.

[0049] The traction rope (30) has a winding end (31) and a connecting end (32), wherein the winding end (31) is wound around the rotating output shaft of the resistance motor (20), and the connecting end (32) is located outside the body and is movably connected in a converter (100).

[0050] The converter (100) is connected to a tensioner (40).

[0051] In practice, the tensioner (40) can be a tension handle, a load bar, or other tensioning device.

[0052] When in use, firstly, the resistance motor (20) works and generates a pulling force (F). Then, the pulling force (F) is transmitted to the converter (100) through the traction rope (30). Finally, the converter (100) transmits the pulling force (F) to the tensioner (40). At this moment, the tensioner (40) applies the pulling force (F) to the human body to bear weight and thus exercise the muscles.

[0053] In practical applications, when the resistance band (40) is a pull handle, the user can pull the pull handle to achieve the purpose of training the upper limb muscles, such as training the biceps, pectoralis major, latissimus dorsi, etc.

[0054] When the resistance band (40) is used as a weight bar, the user can carry the weight bar on their shoulder to train the muscles of the lower limbs, such as leg muscles and hip muscles.

[0055] The resistance motor (20) is able to generate a pulling force (F), which is transmitted to the tensioner (40) through the traction rope (30) and the converter (100).

[0056] The converter (100) has two working modes: direct transmission of tensile force and transmission of tensile force at multiple levels.

[0057] In this direct force transmission mode, the converter (100) can directly transmit the force (F) to the tensioner (40).

[0058] In this multi-level tensile force transmission mode, the converter (100) can convert the tensile force (F) into a multi-level tensile force (Fs), and then transmit the multi-level tensile force (Fs) to the tensioner (40).

[0059] The converter (100) can switch between two operating modes: direct force transmission and multiplier force transmission.

[0060] For ease of understanding, the following example is given. For instance, the pulling force (F) generated by the resistance motor (20) is sixty kilograms. In the direct transmission of pulling force working mode, the converter (100) can directly transmit the sixty kilograms of pulling force (F) to the tensioner (40). In this case, the converter (100) can be a simple hook connector.

[0061] In this multiplier-level tension transmission mode, the converter (100) can convert the 60 kg tension (F) into a multiplier-level tension (Fs) that is two or three times the tension (F), and then transmit the multiplier-level tension (Fs) to the tensioner (40). At this time, the tension on the tensioner (40) is 120 kg or 180 kg. In this case, the converter (100) can be a movable pulley or a pulley block.

[0062] In practical applications, since the product of this invention is used for training human muscles, and the human body has limited load capacity, in practice, in the working mode of transmitting tensile force at multiple levels, it is sufficient to provide double the tensile force to fully meet the needs of the human body's load capacity limit. Moreover, when providing double the tensile force, the product has a simpler structural design and relatively lower manufacturing cost, as described in detail below.

[0063] like Figures 6 to 9 As shown, a resistance training system includes a body (10), a resistance motor (20), and a traction rope (30), wherein the resistance motor (20) is fixedly installed in the body (10).

[0064] The traction rope (30) has a winding end (31) and a connecting end (32), wherein the winding end (31) is wound around the rotating output shaft of the resistance motor (20), and the connecting end (32) is located outside the body (10) and is movably connected in a converter (100).

[0065] The converter (100) is connected to a tensioner (40).

[0066] The resistance motor (20) is able to generate a pulling force (F), which is transmitted to the tensioner (40) through the traction rope (30) and the converter (100).

[0067] The converter (100) has two working modes: direct transmission of tensile force and double transmission of tensile force.

[0068] like Figure 8 As shown, in this direct force transmission mode, the converter (100) can directly transmit the force (F) to the tensioner (40).

[0069] like Figure 9 As shown, in this double-transmission tension mode, the converter (100) can convert the tension (F) into double tension (Fa), and then transmit the double tension (Fa) to the tensioner (40).

[0070] The converter (100) can switch between two operating modes: direct force transmission and double force transmission.

[0071] Since the product of this invention is used for training human muscles, and the human body has a limited load capacity, in practice, the double-transmission tension working method can fully meet the needs of the human body's load capacity limit. Moreover, the double-transmission tension working method is relatively simple in terms of structural design and relatively inexpensive to manufacture.

[0072] When the converter (100) has two working modes, namely the direct transmission of tension and the double transmission of tension, there are several preferred implementation methods in specific implementation, as described below.

[0073] like Figures 10 to 20 As shown, implementation method one, especially as Figures 10 to 11 As shown, the converter (100a) includes a traction rope channel (110a), a free rope hole (111a), a locking rope hole (112a), and a connection end fixing position (113a).

[0074] The free rope hole (111a) and the locking rope hole (112a) are located at the two ends of the traction rope channel (110a), respectively.

[0075] The connection end fixing position (113a) can be set on the body (10) or outside the body (10).

[0076] The traction rope (30) is simultaneously threaded through the traction rope channel (110a), the free rope hole (111a), and the locking rope hole (112a).

[0077] In practice, the traction rope channel (110a) can be either a closed channel or an open channel.

[0078] like Figure 12 As shown, in the direct transmission of tension mode, the tensioner (40) is connected to the converter (100a), and the connecting end (32) of the traction rope (30) is fixed at the locking rope hole (112a).

[0079] The pulling force (F) generated by the resistance motor (20) is directly transmitted to the tensioner (40) through the traction rope (30) and the converter (100a).

[0080] At this moment, the training force (Fc) generated on the resistance device (40) is equal to the pulling force (F) generated by the resistance motor (20), thereby meeting the requirements of the method two small weight fast speed training described in the background art.

[0081] like Figure 13 As shown, in the double-transmission tension mode, the tensioner (40) is connected to the converter (100a), and the connecting end (32) of the traction rope (30) is fixed in the connecting end fixing position (113a).

[0082] The converter (100a) is located between the winding end (31) of the traction rope (30) and the connecting end (32) of the traction rope (30).

[0083] The traction rope (30) forms a first traction rope tension portion (121a) between the converter (100a) and the connection end fixing position (113a).

[0084] The traction rope (30) forms a second traction rope tension portion (122a) between the converter (100a) and the winding end (31).

[0085] The tension (F) generated by the resistance motor (20) is transmitted to the traction rope (30), and the converter (100a) converts the tension (F) into the double tension (Fa), which is then transmitted to the tensioner (40) through the converter (100a).

[0086] At this moment, the training force (Fc) generated on the resistance band (40) is equal to the double pulling force (Fa). The training force (Fc) generated on the resistance band (40) is twice the pulling force (F) generated by the resistance motor (20), thereby meeting the requirements of heavy weight slow speed training as described in the background art.

[0087] like Figure 11 As shown, by fixing the connecting end (32) at the locking rope hole (112a) or in the connecting end fixing position (113a), the switching between the two working modes of direct transmission of tension and double transmission of tension can be realized.

[0088] In other words, when the connecting end (32) is fixed in the locking rope hole (112a), people can perform single-force, low-weight, high-speed training. When the connecting end (32) is fixed in the connecting end fixing position (113a), people can perform double-force, high-weight, slow-speed training. This achieves the goal of doubling the training force (Fc) while keeping the power of the resistance motor (20) constant, and the switching method is simple and reliable.

[0089] In specific implementation, such as Figure 14 As shown, the converter (100a) includes a rotating wheel (130a) and a wheel housing (140a). The rotating wheel (130a) is rotatably disposed in the wheel housing (140a). The traction rope channel (110a) is located between the rotating wheel (130a) and the wheel housing (140a). The free rope hole (111a) and the locking rope hole (112a) are disposed on the wheel housing (140a). The free rope hole (111a) and the locking rope hole (112a) are respectively connected to the traction rope channel (110a).

[0090] In practice, the free rope hole (111a) is located below the wheel housing (140a), and the locking rope hole (112a) is located on one side of the wheel housing (140a) to facilitate the insertion of the traction rope (30) and to facilitate the switching of working modes.

[0091] In practice, the wheel (130a) is provided with a rope groove to facilitate the positioning of the traction rope (30).

[0092] In specific implementation, such as Figure 15 As shown, the wheel housing (140a) includes a cover (141a), a bracket (142a), and a pivot (143a), wherein the pivot (143a) is inserted into the wheel (130a), and both ends of the pivot (143a) pass through the cover (141a) and are pivotally connected to the bracket (142a).

[0093] In practice, the cover (141a) includes a first cover (144a) and a second cover (145a), which are fastened together to form the cover (141a).

[0094] In practice, the hanger (142a) includes a first cap (146a), a second cap (147a), and a hook (148a).

[0095] The first cap (146a) and the second cap (147a) are respectively placed on both sides of the cover (141a).

[0096] The hook (148a) is connected to a connector (149a) for easy connection to the tensioner (40).

[0097] In specific implementation, such as Figure 16 As shown, the connecting end (32) of the traction rope (30) is provided with a clip (150a). The clip (150a) allows the connecting end (32) to be easily fixed in the locking rope hole (112a) or in the connecting end fixing position (113a), so as to facilitate switching between the two working modes of direct transmission of tension and double transmission of tension.

[0098] like Figure 17 As shown, in practice, the card head (150a) includes a fixing part (151a) and a snap-fit ​​part (152a), wherein the fixing part (151a) is used to fix the connecting end (32).

[0099] The snap-fit ​​part (152a) is used to fix the connecting end (32) in the locking rope hole (112a) or in the connecting end fixing position (113a).

[0100] In practice, the fixing part (151a) is the inner cavity of the card head (150a), and the connecting end (32) is fixed in the inner cavity of the card head (150a).

[0101] A retaining ring (153a) can be fitted onto the connecting end (32) for easy fixing.

[0102] In practice, the snap-fit ​​part (152a) includes a tube body and a snap ring, wherein the snap ring protrudes from the end of the tube body.

[0103] In specific implementation, such as Figure 15 As shown, the converter (100a) also includes a traction rope guide (160a).

[0104] The traction rope (30) is threaded through the traction rope guide (160a), which is used to change the direction of the tension transmission of the traction rope (30).

[0105] The traction rope guide (160a) is equipped with a fixed pulley block, through which the traction rope (30) passes.

[0106] In practice, the traction rope guide (160a) is pivotally connected to the body (10).

[0107] The pulley assembly includes a main pulley (161a) and a secondary pulley (162a), with the traction rope (30) threaded between the main pulley (161a) and the secondary pulley (162a).

[0108] The above structure allows the path of the traction rope (30) to be changed at any time during training, making it convenient for people to use.

[0109] In practice, the connection end fixing position (113a) can be implemented in a variety of ways to achieve its function. A preferred implementation is described below.

[0110] like Figure 18 As shown, a first sensor (171a) is provided in the fixed position (113a) of the connection end, and a second sensor (172a) is provided on the connection end (32) of the traction rope (30) corresponding to the first sensor (171a).

[0111] When the connecting end (32) is fixed in the connecting end fixing position (113a) under the double tensile force transmission mode, the first sensor (171a) and the second sensor (172a) sense each other and generate a sensing signal.

[0112] In this direct force transmission mode, no sensing signal is generated between the first sensor (171a) and the second sensor (172a).

[0113] In practice, the sensing signal can be transmitted to the user in the form of sound, image or other forms so that the user can know the working status of the resistance training system. In practice, the sensing signal can be an alarm sound or an image warning icon on the display screen of the resistance training system.

[0114] In practice, the first sensor (171a) can be a magnetic sensor, and the second sensor (172a) can be a magnetic block.

[0115] In specific implementation, such as Figure 19As shown, the connecting end fixing position (113a) includes a fixing hole (181a) and a card cover (182a). Corresponding to the fixing hole (181a), a card head (150a) is provided on the connecting end (32).

[0116] like Figure 13 As shown, in the double-transmitting tensile force working mode, the card head (150a) is inserted into the fixing hole (181a), and the card cover (182a) is snapped onto the card head (150a), thereby fixing the card head (150a) in the fixing hole (181a).

[0117] like Figure 12 As shown, in the direct transmission of tension working mode, the cover (182a) is opened, the clip (150a) is pulled out from the fixing hole (181a), and the clip (150a) is engaged with the locking rope hole (112a) of the converter (100a).

[0118] like Figure 17 , 18 As shown, in a specific implementation, the first sensor (171a) is disposed in the fixing hole (181a), and the second sensor (172a) is disposed in the card head (150a).

[0119] In specific implementation, such as Figure 19 As shown, the connecting end fixing position (113a) is located on the traction rope guide (160a). The cover (182a) is a push-pull cover.

[0120] like Figures 21 to 25 As shown, implementation method two, as Figure 21 As shown, the converter (100b) includes a double-force pulley (110b).

[0121] In this direct force transmission mode, the tensioner (40) is connected to the connection end (32) of the traction rope (30), and the tension (F) generated by the resistance motor (20) is directly transmitted to the tensioner (40) through the traction rope (30).

[0122] like Figure 22 As shown, in the double-force transmission mode, the tensioner (40) is connected to the double-force pulley (110b), the double-force pulley (110b) is located between the winding end (31) of the traction rope (30) and the connecting end (32) of the traction rope (30), and the connecting end (32) is fixedly connected to a fixed position (120b).

[0123] The traction rope (30) forms a first traction rope tension portion (131b) between the double-force pulley (110b) and the fixed position (120b).

[0124] The traction rope (30) forms a second traction rope tension portion (132b) between the double-force pulley (110b) and the winding end (31).

[0125] The pulling force (F) generated by the resistance motor (20) is transmitted to the traction rope (30), and the double force pulley (110b) converts the pulling force (F) into the double pulling force (Fa), which is then transmitted to the tensioner (40) through the double force pulley (110b).

[0126] As mentioned above, in practice, the double-force pulley (110b) can essentially be a movable pulley.

[0127] For ease of understanding, the following example is given: For instance, the pulling force (F) generated by the resistance motor (20) is less than 60 kg. In the direct transmission of pulling force working mode, the pulling force (F) of less than 60 kg is directly transmitted to the tensioner (40) to meet the requirements of the small weight and fast speed training described in the background art.

[0128] In this double-force transmission mode, the double-force pulley (110b) converts the force (F) into the double force (Fa), which is then transmitted to the tensioner (40). At this moment, when the force (F) is 60 kg, the double force (Fa) is 120 kg, thus meeting the requirements of heavy weight slow-speed training as described in the background art.

[0129] In addition, the connecting end (32) of the traction rope (30) can be movably connected to the tensioner (40) or the fixed position (120b) by means of binding, wrapping or other methods, so as to realize free switching between the two working modes of direct transmission of tension and double transmission of tension.

[0130] In practice, the fixed position (120b) is set on the body (10).

[0131] In practice, a fixed pulley (140b) is provided in the body (10), and the traction rope (30) is wound around the fixed pulley (140b). The fixed pulley (140b) can change the trajectory of the traction rope (30) and improve the transmission path of the tension (F).

[0132] In practice, the converter (100b) also includes a direct-guide pull buckle (150b).

[0133] like Figure 23As shown, in the direct transmission of tension working mode, the tensioner (40) is connected to the direct guide tension buckle (150b), and the connecting end (32) of the traction rope (30) is connected to the direct guide tension buckle (150b).

[0134] The pulling force (F) generated by the resistance motor (20) is directly transmitted to the tensioner (40) through the traction rope (30) and the direct-guide tension buckle (150b).

[0135] like Figure 24 As shown, the straight-guide pull buckle (150b) is a pull-hole retainer (151b), such as a hook.

[0136] The fixing position (120b) is provided on the body (10), and the fixing position (120b) is provided with a fixing fixture (121b), such as a hook or a hanging rod.

[0137] The tension port retainer (151b) corresponds to the fixed position retainer (121b).

[0138] In this double-transmitting tensile force operation mode, the tensile force port retainer (151b) is connected to the fixed position retainer (121b).

[0139] In specific implementation, such as Figure 23 As shown, the machine body (10) is provided with a limit rope outlet hole (160b), and the connecting end (32) of the traction rope (30) passes through the limit rope outlet hole (160b).

[0140] The straight-guide pull buckle (150b) can be engaged in the limiting rope outlet hole (160b) to limit the straight-guide pull buckle (150b) and prevent the connecting end (32) from retracting into the body (10) and affecting its use.

[0141] In specific implementation, the fixing position (120b) is a fixing hole, and the fixing position fixing device (121b) is set in the fixing hole. In the double tensile force transmission working mode, the tensile force port fixing device (151b) is connected to the fixing position fixing device (121b), and the tensile force port fixing device (151b) is located in the fixing hole.

[0142] In practice, the machine body (10) is provided with a pulley receiving groove (170b) to accommodate the double force pulley (110b) for easy use.
