[0002] 2. Description of the Related Art In the past, treadmills such as those described in Patent Document 1 have been proposed to meet the two needs of consumers, namely, anaerobic exercise and aerobic exercise.

[0003] The treadmill described in Patent Document 1 includes a running belt assembly, two handrail assemblies, and a tensioner. The tensioner includes a resistance assembly, an adjustment assembly, and a traction assembly. The resistance assembly includes a first disk, a pulley, a belt, a weight, and a friction member. The pulley rotates synchronously with the first disk. The belt is wound around the pulley, and one end of the belt is connected to the weight and the other end is connected to the traction assembly. The adjustment assembly controls the force with which the friction member contacts the first disk. Therefore, this treadmill allows ordinary consumers to perform both aerobic and anaerobic exercises with just one device, saving space and money. Furthermore, the resistance of the tension device comes from the weight and friction member, which significantly reduces the cost and volume of the fitness device, allowing ordinary consumers to purchase muscle training equipment at an affordable price.

[0027] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. It goes without saying that the present invention is not limited to the following examples, and that any modifications can be made without departing from the spirit and scope of the present invention.

[0028] 1 to 4 show a pulling and running training device according to an embodiment of the present invention. In this embodiment, in the space in which the pulling and running training device exists, three mutually perpendicular directions are defined as X direction, Y direction, and Z direction.

[0029] The pulling and running training device includes a frame 1, two power units 2, two first clutch units 3, two second clutch units 4, a running mechanism 5, a pulling mechanism 6, a locking mechanism 7, and a control unit 8.

[0030] The frame 1 includes a handle 11 and a display unit 12, which are installed adjacent to each other. The display unit 12 may be a general display with a display function or a touch panel that can be operated.

[0031] The two power units 2 are adjacent to each other in the X direction (width direction) and are both installed on the frame 1. The power units 2 are, for example, brushless DC motors, and each power unit 2 has a power shaft (not shown) extending to the outside on both sides of the power unit 2.

[0032] The two first clutch units 3 are each coupled to one end of the power shaft. Two second clutch units 4 are respectively coupled to the other end of the power shaft. The first clutch unit 3 and the second clutch unit 4 may both be electromagnetic clutches. Since the technology of electromagnetic clutches is mature and well known, detailed explanations of the internal structure and working principles of electromagnetic clutches will be omitted.

[0033] The running mechanism 5 is mounted on the frame 1 . The running mechanism 5 includes two drive wheels 51, two belts 52, two driven wheels 53, a drive shaft 54, a driven shaft 55, and a running belt 56, and the handle 11 and the display unit 12 are spaced a certain distance apart from the running belt 56 in the Z direction (height direction). The driving wheels 51 are respectively coupled to one side of the first clutch unit 3, spaced apart from the power shaft, and belts 52 are respectively connected to the driving wheels 51. The belts 52 are respectively connected to driven wheels 53, and the driven wheels 53 are both connected to a driving shaft 54. One end of a running belt 56 is wound around the driving shaft 54, and the other end is wound around a driven shaft 55.

[0034] The tensioning mechanism 6 is mounted on the frame 1. The tensioning mechanism 6 includes two cable reels 61, two guide pulleys 62, two first diverting pulleys 63, two second diverting pulleys 64, two cables 65, and two grips 66. The cable reels 61 are respectively coupled to one side of the second clutch units 4 that is spaced apart from the power shafts, and are adjacent to the running belt 56 in the Y direction. The guide pulley 62 and the first diverting pulley 63 are both installed below the running belt 56 in the Z direction, and the second diverting pulleys 64 are installed below the frames 1 in the Z direction on both sides of the running belt 56. The guide pulley 62 and the first diverting pulley 63 are adjacent to each other in the Y direction, and the first diverting pulley 63 and the second diverting pulley 64 are adjacent to each other in the X direction.

[0035] The cable 65 is wound around the cable reel 61, enters below the running belt 56 in the Y direction, passes through the guide pulley 62 while maintaining the Y direction, is then redirected by the first direction-changing pulley 63 and extended along the X direction or in the direction opposite to the X direction, is further redirected by the second direction-changing pulley 64 and extended along the Z direction in either case, passes through the frames 1 on the sides of the running belt 56, and is connected to the grips 66 on the frames 1 on both sides of the middle part of the running belt 56.

[0036] The cable 65 is largely hidden beneath the running belt 56 or beneath the frame 1, greatly reducing the chance of dust or other foreign matter getting into the tensioning mechanism 6 and becoming caught. The guide pulley 62 not only helps to limit the movement of the cable 65 in the X direction, but also, when properly positioned, serves as a tensioning mechanism to help tension the cable 65 .

[0037] The locking mechanism 7 is mounted on the frame 1. The locking mechanism 7 includes a locking wheel 71, a plunger 72, and a locking power unit 73. The lock wheel 71 is coupled to the drive shaft 54 ​​, and a plurality of lock holes 711 are provided on the lock wheel 71 , and a lock power unit 73 is connected to the plunger 72 . The lock power unit 73 may be a brushless DC motor. Preferably, the drive shaft 54 ​​includes an external sleeve portion for connecting the running belt 56, and an internal shaft portion for pivotally connecting to the frame 1, and the lock wheel 71 can be connected on the shaft center.

[0038] The control unit 8 is signal-connected to the display unit 12 , the power unit 2 and the lock power unit 73 . When the display unit 12 is a general display, it is preferably equipped with a control panel (not shown) that can be used for various subsequent controls. When the display unit 12 is a touch panel, you can choose to use the control panel or directly use the touch panel to perform various subsequent controls.

[0039] Please refer to FIG. 4 in conjunction with FIGS. 2, 5 and 6. User A can operate the display unit 12 to select the running training mode.

[0040] At this time, under the control of the control unit 8, the first clutch units 3 are all engaged and the second clutch units 4 are all disengaged, and the power unit 2 drives and operates the running mechanism 5, but does not drive and operate the pulling mechanism 6.

[0041] More specifically, the power shaft rotates in the forward direction, which in turn rotates the drive shaft 54 ​​in the forward direction via the drive wheel 51, belt 52, and driven wheel 53 (FIG. 3). The drive shaft 54 ​​further drives the running belt 56, which rotates the drive shaft 54 ​​and the driven shaft 55 (FIG. 1), allowing the user A to perform running training on the running belt 56.

[0042] Please refer to FIG. 4 in conjunction with FIGS. 6-9. If user A wants to switch to two-handed pulling training, he can similarly operate the display unit 12 to select the two-handed pulling training mode.

[0043] First, the lock power unit 73 is activated under the control of the control unit 8, and the lock power unit 73 drives the plunger 72 to insert it into one of the lock holes 711, and the plunger 72 locks the drive shaft 54 ​​to prevent it from rotating, and the running belt 56 also does not rotate.

[0044] This allows the user A to stand directly on the running belt 56 and operate the tensioning mechanism 6, further saving space required on the side of the tensioning and running training device.

[0045] In actual practice, the lock power unit 73 may not be installed, and the user A may directly insert the plunger 72 into one of the lock holes 711 manually.

[0046] Please refer to Figure 4 in addition to Figures 2, 9, and 10. Next, under the control of the control unit 8, all second clutch units 4 are engaged and all first clutch units 3 are disengaged, so that the power unit 2 drives and operates the tensioning mechanism 6, but does not drive and operate the running mechanism 5.

[0047] At this time, the power shaft drives the cable reel 61 to rotate in the forward direction, recovering the cable 65 through the cable reel 61 and providing resistance to the cable 65 to prevent user A from pulling it out.

[0048] User A bends down with palms facing downwards, grasps grips 66 with both hands, then stands up and stretches both hands upward to resist the resistance, thereby pulling out cable 65. At this time, cable reel 61 rotates in the reverse direction opposite to the forward rotation direction, releasing cable 65, and user A can achieve two-handed pulling training.

[0049] As shown in FIG. 11, in addition to the palm-down method, user A can achieve another method of two-handed pulling training by bending down with palms facing up and grasping grips 66 with both hands, then standing up and stretching both hands upward to counter the resistance and pull out cable 65.

[0050] Please refer to Figure 4 in addition to Figures 2, 9, and 11. Because the grips 66 are located on the sides of the moving belt 56, in any method of two-handed pulling training, in addition to training the arms, user A can also train the lower limbs by repeatedly bending and standing up to grasp the grips 66.

[0051] Furthermore, since the grip 66 is located on the side of the middle part of the running belt 56 and the user A also stands in the middle part of the running belt 56 to operate the pulling mechanism 6, it is possible to avoid the problem of the pulling and running training device being lifted or overturned due to a change in the center of gravity of the user A and the entire pulling and running training device.

[0052] According to the user A's own needs, the magnitude of the output torque of the two power units 2 may be controlled via the control unit 8 to apply different magnitudes of resistance to the cables 65 on both sides.

[0053] Please refer to Figure 4 in conjunction with Figures 2, 12 and 13. User A can further operate the display unit 12 to select a one-handed pulling training mode.

[0054] User A can choose to stand on the running belt 56 or on the side of the pulling and running training device, and can pull the cable 65 with the arm he wants to train, just like in the two-handed pulling training shown in Figures 9 and 11. User A can also train his lower limbs by repeatedly bending and standing up in the same way.

[0055] As shown in Figures 5, 9, 11, and 12, one pulling and running training device can be used to select running training, one-arm pulling training, or two-arm pulling training according to one's needs, and it can effectively save the space required for the machine, so it can be used not only in gyms but also in ordinary homes, which have less space than gyms, and is suitable for exercising at home.

[0056] The above describes the best mode for carrying out the present invention, and does not limit the scope of the invention. All changes and modifications that do not deviate from the scope of the utility model claims are included within the scope of the invention. [Explanation of symbols]
