[0001] The utility model relates to a kind of tension training device, feet can be treaded on pedal to keep balance, prevent falling during training. BACKGROUND

[0002] The general common fitness training device currently, resistance unit will be set, to have a rotating resistance when training, to provide different rotating resistance for the trainer to select different rotating resistance for training according to different training modes.

[0003] On November 11, 2022, the new type of patent No. TWM633954 "compound force applying structure of rowing machine" announced by Taiwan, China. It is disclosed that: it includes a base frame, a rowing unit, a first rotating shaft, a rowing linkage unit, a resistance unit, a pull handle unit, a second rotating shaft and a pull handle linkage unit; a first operating force is applied to the rowing unit, driving the rowing one-way drive wheel and the first rotating shaft to rotate in the first rotating direction, and when the first operating force decreases or disappears, the rowing one-way drive wheel is driven to idle in the second rotating direction on the first rotating shaft; a second operating force is applied to the pull handle unit, driving the pull handle linkage unit to rotate in the first rotating direction, and when the second operating force decreases or disappears, the second restoring force drives the pull one-way wheel to idle in the second rotating direction on the second rotating shaft. In this way, the compound training effect of rowing and pull handle can be achieved.

[0004] The resistance unit of the prior art is arranged on the base frame, resulting in large overall volume and heavy weight, and cannot be arbitrarily dragged and moved, and cannot be used for other different specifications of rowing machines or other types of fitness equipment.

[0005] On September 11, 2024, the invention patent No. TWI855983 "resistance unit and fitness device combined with resistance unit" announced by Taiwan, China. It is disclosed that: the resistance unit includes a seat; an electric resistance unit is fixed on the seat; a reel is fixed on the output shaft of the electric resistance unit and rotates with the output shaft, and the electric resistance unit gives the reel a rotating resistance; a cable is fixed and wound on the reel, which can be used independently for fitness. The fitness device combined with the resistance unit includes a resistance unit which is fixed on at least one fitness equipment frame to be installed on any fitness device.

[0006] Although the prior art can be used independently, when single-hand training is performed, since it can only provide single-foot stepping, the other foot is standing on the ground, therefore the height of the two feet standing is different, which easily causes the two feet to be unbalanced and fall, causing danger. Moreover, the overall weight is heavy, which is not easy to carry and move, so it is not ideal in use. UTILITY MODEL CONTENTS

[0007] Therefore, in view of the above-mentioned shortcomings of the currently known tensile training devices, the purpose of this utility model is to provide a tensile training machine.

[0008] This utility model provides a resistance training machine, comprising: a base including a housing extending longitudinally, and two pedals located on both sides of the housing and extending laterally outwards; an electric resistance unit fixed inside the housing, the electric resistance unit having an output shaft for transmitting power; a reel fixed to the output shaft and rotating with the output shaft, the electric resistance unit imparting rotational resistance to the reel; a cable, one end fixed and wound around the reel, the other end being a free end extending out of the housing; a control unit disposed inside the housing and signal-connected to the electric resistance unit; and a control button disposed on the outer surface of the housing and electrically connected to the control unit; by applying an external force to the free end, the cable is pulled to overcome the rotational resistance; when the external force decreases, the electric resistance unit retracts the cable through the reel; and by adjusting the control button, the rotational resistance can be changed through the control unit.

[0009] The aforementioned electric resistance unit is either a motor or an electromagnetic brake.

[0010] The aforementioned electric resistance unit is located at one end of the housing, while the free end of the cable is located at the other end of the housing.

[0011] The aforementioned electric resistance unit and the rotation axis of the reel are horizontally arranged along the transverse direction, and the cable passes through a horizontal reel and a vertical reel respectively before exiting the housing.

[0012] The aforementioned free end selectively engages with a gripping member, the free end having a first engaging member, and the gripping member having a second engaging member, the first engaging member and the second engaging member being detachably engaged or disengaged from each other.

[0013] The first coupling has a notch, and a closing pin is movably provided on the side of the first coupling. Pressing or releasing the closing pin can close or open the notch, so that the first coupling can be engaged or disengaged from the second coupling.

[0014] The aforementioned grip is either a single-handed handle or a two-handed grip.

[0015] The container has a handle at one end and two wheels at the other end.

[0016] The aforementioned container is composed of an outer shell and a base. The two pedals are respectively disposed on both sides of the base. The top surface of the outer shell has a through hole, through which the free end passes out of the container.

[0017] The top surface of the aforementioned housing has a through-hole, through which the control button extends and is located on the outer surface of the housing.

[0018] The above-mentioned technical features have the following advantages:

[0019] 1. The resistance training machine has the advantages of small size, light weight, no space occupation, and easy movement and portability. In particular, it allows trainees to use the resistance training machine to carry out fitness training alone in a small space.

[0020] 2. Two pedals extend outward from both sides of the seat, allowing the operator to place their feet on each pedal. The operator's own weight helps to stabilize the seat on the ground and prevent displacement during training.

[0021] 3. Further utilize the operator's feet to step on the pedal, so that the operator's feet can be at the same level and maintain stable balance, so as not to tilt or fall.

[0022] 4. The grip can be configured as a single-handed handle, allowing the operator to hold the grip with one hand and pull it up and down alternately with one hand. This applies a pulling force through the grip and the cable to overcome the rotational resistance, thus enabling single-handed fitness training.

[0023] 5. The grip can be a two-handed grip structure, so that the operator can hold the two ends of the grip with both hands respectively, and pull the grip up and down in sync with both hands. The grip and the cable can apply a pulling force to overcome the rotational resistance, which can be used for fitness training that simulates lifting a barbell with both hands.

[0024] 6. The handle at one end of the container can be held with one hand, so that the two rollers at the other end of the container are on the ground. Then, the base can be tilted and force can be applied to the handle to move the base in a labor-saving and convenient way, so that it can be placed in any position. Attached Figure Description

Detailed Implementation

[0036] Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a resistance training machine, comprising: a base 1, an electric resistance unit 2, a reel 3, a cable 4, a control unit 5, and a control button 6, wherein:

[0037] The seat 1 includes a receiving box 11 extending longitudinally along the X direction, and two wing-shaped footrests 12 located on both sides of the receiving box 11 and extending outwardly along the transversely Y direction for the feet to step on. The receiving box 11 is a closed box consisting of an outer shell 111 and a base 112. The top surface of the outer shell 111 is provided with a through hole 13 and an opening 14, and the two footrests 12 are respectively disposed on both sides of the base 112. Furthermore, one end of the base 112 of the receiving box 11 is provided with a handle 15, and the other end of the base 112 is provided with two rollers 16, so that the handle 15 can be lifted upward to make the two rollers 16 touch the ground to tilt the seat 1, and then force can be applied to the handle 15 to drag the seat 1.

[0038] An electric resistance unit 2 is fixed inside the housing 11. The electric resistance unit 2 is a motor or an electromagnetic brake, located at one end of the housing 11. The electric resistance unit 2 is electrically connected to a power supply terminal 21 and a power switch 22. Both the power supply terminal 21 and the power switch 22 are exposed at one end of the base 112. The power supply terminal 21 can be plugged into a mains power source to supply the power required for the operation of the electric resistance unit 2. The power switch 22 is used to start or stop the power supply to the electric resistance unit 2. The electric resistance unit 2 has an output shaft 23 for transmitting power.

[0039] The reel 3 is fixed to the output shaft 23 of the electric resistance unit 2 and is located inside the housing 11. The reel 3 rotates with the output shaft 23, and the electric resistance unit 2 provides rotational resistance to the reel 3. The rotation axes of the electric resistance unit 2 and the reel 3 are horizontally arranged along the transverse Y-axis.

[0040] Cable 4, one end of which is fixed and wound around reel 3, has a free end 41 at the other end. The free end 41 passes sequentially over a horizontal reel 42 and a vertical reel 43 [as shown in the image]. Figure 4 As shown], the free end 41 extends through the through hole 13 to the other end of the receiving box 11. A grip 44 can be selectively engaged with the free end 41. The grip 44 is a single-handed handle, or the grip 44A is a two-handed handle [e.g., Figure 5 [As shown]. The free end 41 is provided with a first coupling 45 having a notch 451 [as shown]. Figure 6 [As shown], a closing pin 452 is movably provided on the side of the first connecting member 45, and a second connecting member 46 is provided on the gripping member 44. By pressing or releasing the closing pin 452, the notch 451 is closed or opened, allowing the first connecting member 45 and the second connecting member 46 to be detachably connected or disconnected from each other. The rotational resistance is obtained by detachably connecting the free end 41 to the gripping member 44. An external force, which is a tension force, is applied to the free end 41 through the gripping member 44 to pull the cable 4 to overcome the rotational resistance. When the external force decreases, the electric resistance unit 2 retracts the cable 4 through the reel 3.

[0041] The control unit 5 is disposed inside the housing 11 and is signal-connected to the electric resistance unit 2, thereby controlling the magnitude of the rotational resistance output by the electric resistance unit 2.

[0042] The control button 6 extends from the opening 14 and is disposed on the outer surface of the housing 11. The control button 6 is electrically connected to the control unit 5. By adjusting the control button 6, the rotational resistance can be changed via the control unit 5.

[0043] Please seeFigure 1 , Figure 2 and Figure 3 As shown, when performing single-handed fitness training, the grip 44 is pre-selected as a single-handed grip, and then the control knob 6 is rotated to adjust the settings in the control unit 5, thereby automatically controlling the magnitude of the rotational resistance output by the electric resistance unit 2. Figure 7 As shown, operator B places both feet on the two pedals 12 extending horizontally towards the Y side of the housing 11. Using operator B's own weight, the seat 1 is stabilized on the ground to prevent displacement. Simultaneously, operator B's feet are at the same horizontal level, maintaining stable balance and preventing tilting and falling. Then, operator B holds the grip 44 at the free end 41 of the cable 4 with one hand. By alternately pulling the grip 44 up and down with one hand, operator B applies external force (tension) through the grip 44 and the cable 4, overcoming the rotational resistance output by the output shaft 23 of the electric resistance unit 2, allowing for single-handed fitness training.

[0044] Please see Figure 3 , Figure 5 and Figure 8 As shown, when performing two-handed fitness training, the grip 44A can be changed to a two-handed grip bar. The closing pin 452 must be pressed first. Figure 9 As shown, the closing pin 452 is no longer closed on the notch 451, allowing the notch 451 to be opened so that the second connecting member 46 can disengage from the first connecting member 45 through the notch 451. Then, another grip 44A is installed for the two-handed grip, and the second connecting member 46 of the grip 44A can be inserted through the notch 451. Then, the closing pin 452 is released so that the closing pin 452 can close the notch 451 to prevent the first connecting member 45 and the second connecting member 46 from moving away from each other. By rotating the control knob 6, the control unit 5 is adjusted and set so that the magnitude of the rotational resistance output by the electric resistance unit 2 can be automatically controlled. The operator B's feet are placed on the two pedals 12 on both sides of the housing 11, and the weight of the operator B is used to stabilize the seat 1 on the ground to prevent displacement. Simultaneously, operator B's feet can be at the same horizontal level, maintaining stable balance and preventing tilting or falling. Then, operator B's hands simultaneously grip both ends of the grip 44A. Operator B's hands synchronously pull the grip 44A up and down, applying external force (tension) through the grip 44A and the cable 4 to overcome the rotational resistance output by the output shaft 23 of the electric resistance unit 2, allowing for fitness training simulating lifting a barbell with both hands.

[0045] When it is necessary to move the base 1, such as Figure 10 As shown, the grip 44 can be separated from the cable 4 first. Then, the operator B can hold the handle 15 at one end of the base 112 of the container box 11 with one hand, so that the two rollers 16 at the other end of the base 112 touch the ground. Then, the seat 1 can be tilted and force can be applied to the handle 15, so that the seat 1 can be moved with ease and effort, and placed in any position.

[0046] Thus, the resistance training machine of this utility model has the advantages of small size, light weight, space-saving, easy to move and carry, and can be used alone for resistance training. In particular, it allows trainees to use this resistance training machine for fitness training in a small space. Two pedals 12 extend outward from both sides of the base 1, allowing the operator B to place both feet on the pedals 12 respectively, ensuring that the operator's feet are at the same level and maintaining stable balance, preventing tilting and falling. Furthermore, the grips 44 and 44A can be configured as single-handed handles or double-handed grips, allowing the operator to perform fitness training with one hand or both hands simultaneously.

[0047] Based on the above description of the embodiments, it should be fully understood that the operation, use and effects of the present invention are as follows. The above embodiments are only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All simple equivalent changes and modifications made based on the content of the present invention are within the scope of the present invention.
