Abstract
Description
[Technical field]
[0001] The present invention relates to a pulling training device in which training is performed by stepping on a step board with both feet and pulling a cable. [Background technology]
[0002] A typical training device is equipped with a resistance unit and is provided with rotational resistance, allowing the user to select different rotational resistance forces based on various training modes during training.
[0003] Conventionally, Patent Document 1 discloses a "composite force acting structure for a rowing machine", which includes a base frame, a paddle unit, a first rotating shaft, a paddle link unit, a resistance unit, a pull bar unit, a second rotating shaft, and a pull bar link unit. When a first acting force is applied to the paddle unit, the paddle unidirectional drive wheel and the first rotating shaft are rotated in a first rotation direction, and when the first acting force is reduced or eliminated, the paddle unidirectional drive wheel rotates freely on the first rotating shaft in a second rotation direction. When a second acting force is applied to the pull bar unit, the pull bar link unit is rotated in a first rotation direction, and when the second acting force is reduced or eliminated, the pull bar unidirectional wheel rotates freely on the second rotating shaft in a second rotation direction due to the second return force. This allows a combined training effect to be achieved by using both the paddle and the pull bar.
[0004] The device described in Patent Document 1 above has a resistance unit mounted on a base frame, which results in a large overall volume and heavy weight, making it impossible to pull and move around freely, and it cannot be used in conjunction with rowing machines of different specifications or other types of fitness equipment.
[0005] Patent Document 2 discloses a "resistance unit and fitness device combining the resistance unit," in which the resistance unit includes a seat body, an electric resistance unit fixed to the seat body, a reel fixed to the output shaft of the electric resistance unit and rotating together with the output shaft to provide rotational resistance to the electric resistance unit, and a cable fixed to and wound around the reel, and can be used for fitness on its own. A fitness device having an associated resistance unit has a resistance unit removably secured to at least one fitness device frame and can be used with any fitness device.
[0006] Although the device described in Patent Document 2 can be used alone, when training with one hand, only one foot is stepped on and the other foot is placed on the ground, so the heights of the two feet are different, and it is dangerous because the balance between the two feet is lost and it is easy to fall.In addition, the overall weight is relatively heavy and it is not easy to transport and move, so it cannot be said to be ideal in terms of use.

[0027] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1, 2 and 3, in an embodiment of the present invention, the tension training device includes a seat 1, an electric resistance unit 2, a reel 3, a cable 4, a control unit 5 and a control knob 6.
[0028] The seat body 1 includes a storage box 11 extending along a vertical direction X, and two footboards 12 on wings located on both sides of the storage box 11 and extending horizontally along a horizontal direction Y toward the outside, and the footboards 12 are provided for stepping on by the soles of the feet of a human body. The storage box 11 is composed of a case 111 and a base 112, and is a closed box body with the case 111 covering the upper part of the base 112. A through hole 13 and an opening 14 are provided on the upper surface of the case 111, and two step boards 12 are installed on both sides of the base 112. In addition, a handle 15 is provided at one end of the base 112 of the storage box 11, and two casters 16 are provided at the other end of the base 112, so that the handle 15 can be lifted upward, the two casters 16 can be placed on the ground, the seat body 1 can be tilted, and then the handle 15 can be pulled to move the seat body 1.
[0029] The electric resistance unit 2 is fixed inside the containing box 11. The electric resistance unit 2 is a motor or an electromagnetic brake, and is installed at one end of the containing box 11. The electric resistance unit 2 includes an electrically connected power supply end 21 and a power switch 22. The power supply end 21 and the power switch 22 are both provided at one end of the base 112 and exposed to the outside. The power supply terminal 21 is used to connect to a commercial power source, and can supply the power required for operating the motorized resistance unit 2. The power switch 22 is used to turn the power supply to the motorized resistance unit 2 on and off. In addition, an output shaft 23 that transmits power to the electric resistance unit 2 is installed.
[0030] The reel 3 is fixed to the output shaft 23 of the electric resistance unit 2, and is disposed in the housing box 11. The reel 3 rotates together with the output shaft 23, and the electric resistance unit 2 applies a rotational resistance force to the reel 3. The rotation axes of the electric resistance unit 2 and the reel 3 are arranged horizontally along the lateral direction Y.
[0031] One end of the cable 4 is fixedly wound around the reel 3, and the other end of the cable 4 is a free end 41. The free end 41 is wound around a horizontal rotating wheel 42 and a vertical rotating wheel 43 in sequence (see Figure 4), and then pulled out from the other end of the storage box 11 through the through hole 13. A handle 44 may be selectively coupled to the free end 41. Handle 44 is a one-handed handle, and handle 44A is a two-handed handlebar (see FIG. 5). The free end 41 has a first connecting member 45 with an opening 451 (see FIG. 6), and a lock pin 452 is movably mounted on a side of the first connecting member 45. The handle 44 is provided with a second connecting member 46, and by pressing or releasing the lock pin 452, the opening 451 can be closed or opened, and the first connecting member 45 and the second connecting member 46 can be removably connected or separated from each other. A handle 44 is removably connected to the free end 41 to provide a rotational resistance force, and an external force is applied to the free end 41 through the handle 44. The external force is a traction force, which pulls the cable 4 to overcome the rotational resistance force, and when the external force is reduced, the motorized resistance unit 2 retrieves the cable 4 through the reel 3.
[0032] The control unit 5 is installed in the housing box 11, and is signal-connected to the electric resistance unit 2. This controls the magnitude of the rotational resistance force output by the electric resistance unit 2.
[0033] The control knob 6 protrudes from the opening 14 and is mounted on the outer surface of the receiving box 11. The control knob 6 is electrically connected to the control unit 5. By adjusting the control knob 6, the rotational resistance force is changed through the control unit 5.
[0034] As shown in Figures 1, 2 and 3, when training with one hand is required, the handle 44 for one hand is selected in advance, and by turning the control knob 6, the control unit 5 adjusts the settings, and the magnitude of the rotational resistance force output by the electric resistance unit 2 can be automatically controlled. As shown in Fig. 7, operator B steps on the two footboards 12 extending horizontally in the lateral direction Y on both sides of the storage box 11, respectively, and the weight of operator B is utilized to stabilize the seat body 1 on the ground and prevent it from slipping. At the same time, operator B's feet are positioned at the same horizontal height, and the balance of both feet is stably maintained, so that operator B does not inadvertently tilt and fall. Thereafter, operator B grasps handle 44 attached to free end 41 of cable 4 with one hand. Operator B repeatedly pulls handle 44 up and down with each hand in turn, thereby applying an external force (pulling force) through handle 44 and cable 4, overcoming the rotational resistance force output by output shaft 23 of electric resistance unit 2, and performing one-handed training.
[0035] As shown in Figures 5 and 8, when training both hands is desired, the handle 44A can be changed to a two-handed handlebar. First, when the lock pin 452 is pressed (see FIG. 9) to release the blocking of the opening 451 by the lock pin 452 and open the opening 451, the second connecting member 46 can remove the first connecting member 45 from the opening 451. Thereafter, the handle 44A is replaced with another handle bar that is a two-handed handlebar. After the second connecting member 46 of the handle 44A is inserted through the opening 451, the lock pin 452 is released, whereby the lock pin 452 closes the opening 451, and the first connecting member 45 and the second connecting member 46 cannot be separated from each other. Furthermore, by turning the control knob 6, the control unit 5 can adjust the settings to automatically control the magnitude of the rotational resistance force output by the electric resistance unit 2.
[0036] Similarly, both feet of operator B step on two step boards 12 on both sides of the storage box 11, respectively, and the weight of operator B is utilized to stabilize the seat body 1 on the ground and prevent it from slipping. At the same time, both feet of operator B are positioned at the same horizontal height, and the balance of both feet is stably maintained, so that operator B does not tilt and fall over on its own. After that, operator B grasps both ends of handle 44A with both hands at the same time. When operator B pulls handle 44A up and down repeatedly with both hands at the same time, an external force (pulling force) is applied through handle 44A and cable 4, which overcomes the rotational resistance force output by output shaft 23 of electric resistance unit 2, simulating training in which a barbell is lifted with both hands.
[0037] Furthermore, when it is necessary to move the seat 1, as shown in FIG. 10, the operator B first separates the handle 44 and the cable 4, then grasps the handle 15 at one end of the base 112 of the storage box 11 with one hand, places the two casters 16 at the other end of the base 112 on the ground, tilts the seat 1, and then pulls the handle 15, allowing the operator to easily pull and move the seat 1 without exerting any force, and place it anywhere.
[0038] As a result, the pulling training device of the present invention has the advantages of being small in volume, light in weight, space-saving, easy to move, easy to carry, etc., and can be used alone for pulling training. In particular, an operator can use the pulling training device to train alone even in a small space. In addition, by stepping on the two step boards 12 extending outward from both sides of the seat body 1, the operator B can position both feet at the same horizontal height by stepping on each of the two step boards 12 with both feet, and the balance of both feet is stably maintained, so that the operator will not tilt and fall over. Furthermore, by selectively using the structure of handle 44 to be held with one hand or handlebar-type handle 44A to be held with both hands, the operator can train with one hand or both hands at the same time.
[0039] The above is merely a description of the embodiment of the present invention, and does not limit the scope of the invention, i.e., all changes and modifications that do not deviate from the scope of the utility model claims are within the scope of the invention. [Explanation of symbols]
