Description

Technical Field

[0001] This invention relates to the field of walking-running integrated machine technology, and particularly to a walking-running integrated machine with foldable armrests. Background Technology

[0002] A common problem with existing treadmills that combine walking and running is that the handrails are not needed in the walking mode and need to be folded up, while they are needed in the running mode. Therefore, treadmills that combine walking and running often require switching between the two states of folded and unfolded handrails. The traditional method is to lock the handrails with screws, locking them up when needed and removing them when not needed, which is very cumbersome. Summary of the Invention

[0003] This invention proposes a walking / running machine with foldable armrests, which solves the problem of cumbersome operation when switching between armrest storage and unfolding in existing walking / running machines.

[0004] The specific technical solution of the present invention is as follows: The foldable handrail walking / running machine includes a handrail control panel, two uprights, a control assembly, a locking assembly, and the main body of the walking / running machine. The handrail control panel includes a central control unit with symmetrically arranged handrails fixedly connected to both ends. The upper ends of the two uprights are hinged to the handrail control panel, and the lower ends of the two uprights are hinged to both sides of the walking / running machine main body. The locking assembly is used to lock or release the lower ends of the uprights from the sides of the walking / running machine main body. The control assembly is used to control the locking and releasing of the locking assembly. This walking / running machine has both walking machine and treadmill modes. When the uprights are lifted and the handrail control panel is flattened, the handrail control panel locks the locking assembly through the control assembly, transforming it into treadmill mode. When the handrail control panel is lifted and the uprights are flattened, the handrail control panel releases the locking assembly through the control assembly, transforming it into walking machine mode.

[0005] Furthermore, the control assembly includes an armrest connecting plate, a control ring, two control ropes, a control rotation tube, an upper column connecting plate, a lower column connecting plate, and two column rotating shafts. The armrest connecting plate is fixedly connected to the end of the armrest away from the center console. Symmetrically arranged armrest rotating shafts and rotation drive shafts are fixed to the opposite surfaces of the two armrest connecting plates. A drive shaft groove that mates with the rotation drive shaft is formed on the circumferential surface of the control ring. One end of each of the two control ropes is symmetrically fixed to the control ring, and the other ends of the two control ropes... One end is symmetrically fixed to the control rotating tube. The column is a hollow column tube, through which two control ropes pass. Two radial control shafts are fixed on the circumference of the control rotating tube. An upper connecting plate and a lower connecting plate are fixedly connected to the upper and lower ends of the column, respectively. A handrail rotating shaft sleeve that mates with the handrail rotating shaft is fixed through the upper connecting plate, and a control shaft sleeve is fixed through the lower connecting plate. The control shaft sleeve has a spiral groove that mates with the control shaft. The two column rotating shafts are symmetrically fixed to the walkway. On both sides of the running machine body; the locking assembly includes a state limit shaft, a locking protrusion, and a state limit plate. The state limit shaft and the locking protrusion are both fixed on the side opposite to the control shaft sleeve of the lower connecting plate of the column. The state limit plate is fixed on the end of the column shaft near the running machine body. The state limit plate has a travel limit groove that mates with the state limit shaft, and a locking groove that mates with the locking protrusion. The handrail shaft is rotatably sleeved inside the handrail shaft sleeve, and the control ring rotation sleeve... The rotating drive shaft is located outside the handrail pivot sleeve and is locked in the drive shaft slot. The control tube is sleeved outside the column pivot and the control sleeve is sleeved outside the control rotating tube. The control shaft is slidably set in the spiral groove. The control shaft is used to drive the control sleeve to move axially, thereby causing the locking protrusion to disengage or engage with the locking groove. The status limit shaft is slidably set in the travel limit groove. The end of the column pivot away from the main body of the running machine is provided with an end limit device to prevent the control rotating tube and the control sleeve from disengaging.

[0006] Furthermore, the center console and the two armrests are connected in a U-shape, and the center console is equipped with a display screen and several control buttons.

[0007] Furthermore, the control rope is a steel wire rope, and both ends of the control rope are fixed with limit rope ends.

[0008] Furthermore, an end plate is fixed to one end of the control rotating tube away from the main body of the walking-running machine. A central hole is opened in the middle of the end plate for the column shaft to pass through. The two ends of the control rope are fixed to the control rotating ring and the end plate by fixing bolts. A rope groove for the control rope to pass through is opened axially on the column of the fixing bolt.

[0009] Furthermore, the locking protrusions may be one, two, three, or four, and the corresponding locking grooves may be one, two, three, or four.

[0010] Furthermore, the end limiting device is a nut or a pin, and the end of the column shaft away from the main body of the walking and running machine is provided with a stud section that cooperates with the nut or a pin hole that cooperates with the pin.

[0011] Furthermore, the control shaft is a bolt, and the control rotary tube has a threaded hole that mates with the bolt.

[0012] Furthermore, at least one side of the walking-running machine body is fixed with a support rod, which is used to support the upright column when it is flat.

[0013] Furthermore, the main body of the walking-running machine includes a support frame, a running board, a running belt, and a motor.

[0014] The beneficial effects of the present invention are as follows: The present invention can easily and quickly switch between walking machine mode and treadmill mode. When in treadmill mode, simply lift the control in the handrail and flatten the upright column to switch to walking machine mode. When the upright column is lifted and the control in the handrail is flattened, it switches back to treadmill mode. The switching operation is simple and fast. Attached Figure Description

The upper ends of the two uprights 2 are hinged to the handrail control unit 1, and the lower ends of the two uprights 2 are hinged to both sides of the walking / running machine body 3. The locking component is used to lock or release the lower ends of the uprights 2 and the sides of the walking / running machine body 3. The control component is used to control the locking and releasing of the locking component. This walking / running machine has both walking machine and treadmill modes. When the uprights 2 are lifted and the handrail control unit 1 is laid flat, the handrail control unit locks the locking component through the control component, which is the treadmill mode. When the handrail control unit 1 is lifted and the uprights 2 are laid flat, the handrail control unit releases the locking component through the control component, which is the walking machine mode.

[0020] As a further implementation, the control assembly includes a handrail connecting plate 51, a control ring 52, two control ropes 53, a control rotation tube 54, an upper column connecting plate 55, a lower column connecting plate 56, and two column rotating shafts 57. The handrail connecting plate 51 is fixedly connected to the end of the handrail 12 away from the central control panel 11. Symmetrically arranged handrail rotating shafts 511 and rotation drive shafts 512 are fixed on opposite surfaces of the two handrail connecting plates 51. A drive shaft groove 521 that mates with the rotation drive shaft 512 is provided on the circumferential surface of the control ring 52. One end of each of the two control ropes 53 is symmetrically fixed to the control ring 52. The other end of column 3 is symmetrically fixed to the control rotating tube 54. Column 2 is a hollow tube, through which two control ropes 53 pass. Two radial control shafts 541 are fixed on the circumferential surface of the control rotating tube 54. The upper connecting plate 55 and the lower connecting plate 56 are respectively fixedly connected to the upper and lower ends of column 2. A handrail rotating shaft sleeve 551 that mates with the handrail rotating shaft 511 is fixed through the upper connecting plate 55, and a control shaft sleeve 561 is fixed through the lower connecting plate 56. The control shaft sleeve 561 has a spiral groove 562 that mates with the control shaft 541. The two column rotating shafts 57 are symmetrically fixed to the running and walking sections. On both sides of the main body 3 of the machine; the locking assembly includes a state limiting shaft 61, a locking protrusion 62, and a state limiting plate 63. The state limiting shaft 61 and the locking protrusion 62 are both fixed on the side opposite to the control shaft sleeve 561 of the lower connecting plate 56 of the column. The state limiting plate 63 is fixed on the end of the column rotating shaft 57 near the main body 3 of the machine. The state limiting plate 63 has a travel limiting groove 631 that cooperates with the state limiting shaft 61, and a locking groove 632 that cooperates with the locking protrusion 62. The handrail rotating shaft 511 is rotatably sleeved in the handrail rotating shaft sleeve 551, and the control rotating ring 52 is rotatably sleeved in the handrail. Outside the hand-operated bushing 551, the rotary drive shaft 512 is locked in the drive shaft slot 521. The control rotating tube 54 is sleeved outside the column rotating shaft 57. The control bushing 561 is sleeved outside the control rotating tube 54. The control shaft 541 is slidably arranged in the spiral groove 562. The control shaft 541 is used to drive the control bushing 561 to move axially, thereby causing the locking protrusion 62 to disengage or engage with the locking groove 632. The status limit shaft 61 is slidably arranged in the travel limit groove 631. The end of the column rotating shaft 57 away from the main body 3 of the walking and running machine is provided with an end limit device to prevent the control rotating tube 54 and the control bushing 561 from disengaging.

[0021] As a further implementation, the center console 11 and the two armrests 12 are connected in a U-shape, and the center console 11 is equipped with a display screen and several control buttons.

[0022] As a further implementation, the control rope 53 is a steel wire rope, and both ends of the control rope 53 are fixed with limit rope heads 531, which can be cylindrical, spherical, or other shapes.

[0023] As a further implementation, an end plate 542 is fixed to one end of the control rotating tube 54 away from the main body 3 of the walking and running machine. The end plate 542 has a central hole through which the column shaft passes. The two ends of the control rope 53 are fixed to the control rotating ring 52 and the end plate 542 by fixing bolts 58. The column of the fixing bolt 58 has a rope groove 581 along the axial direction through which the control rope 53 passes.

[0024] As a further implementation, the locking protrusions 62 may be one, two, three, or four, and the corresponding locking grooves 632 may be one, two, three, or four. Two, three, or four are preferred for better reliability.

[0025] As a further implementation, the end limiting device is a nut 59 or a pin, and the end of the column shaft 57 away from the main body of the walking and running machine is provided with a stud section that cooperates with the nut 59 or a pin hole that cooperates with the pin.

[0026] As a further implementation, the control shaft 541 is a bolt, and the control rotary tube 54 has a threaded hole that mates with the bolt.

[0027] As a further implementation, at least one side of the walking-running machine body 3 is fixed with a support rod 31, which is used to support the upright column when it is flat (i.e., the upright column when it is in the walking machine form).

[0028] As a further implementation, the main body 3 of the walking-running machine includes a support frame, a running board, a running belt, and a motor. The main body 3 of the walking-running machine has the same structure as a traditional treadmill, and its specific structure will not be described further. This invention allows for simple and quick switching between walking machine and treadmill modes. In treadmill mode, simply lifting the handlebars and lowering the uprights switches to walking machine mode; lifting the uprights and lowering the handlebars again switches back to treadmill mode. The switching operation is simple and fast.

[0029] The specific process and principle of the switching are as follows: When the invention is in treadmill mode, the upright column 2 is vertical and the handrail control 1 is horizontal. At this time, the control sleeve 561 is close to the state limit plate 63, and the locking protrusion 62 is engaged with the locking groove 632. The lower end of the upright column 2 is locked to the side of the walking-running machine body 3. To switch from treadmill mode to walking machine mode, simply rotate and lift the handrail control 1 so that it is parallel to the upright column 2. During the rotation and lifting of the handrail control 1 along the upper end of the upright column 2, the rotation drive shaft 512 drives the control ring 52 to rotate. The control ring 52 drives the control through the control rope 53. Rotating tube 54 rotates, controlling the control shaft 541 on rotating tube 54 to slide along spiral groove 562, driving control shaft sleeve 561 to move away from state limit plate 63, that is, the lower end of column 2 moves away from state limit plate 63, so that locking protrusion 62 disengages from locking groove 632, and the lower end of column 2 is in a loose state from the side of the walking and running machine body 3. Rotate and flatten column 2 so that column 2 and handrail control 1 are located on both sides and the outer periphery of the end of walking and running machine body 3. 31- Support bar can block column 2 to prevent handrail control 1 and column 2 from being placed directly on the ground.

[0030] To switch from walking machine mode to treadmill mode, simply rotate and lift the upright column 2, then rotate and flatten the handrail control 1. The handrail control 1 is perpendicular to the upright column 2. During the rotation and flattening process, the rotation drive shaft 512 drives the control ring 52 to rotate. The control ring 52 controls the rotation tube 54 to rotate via the control rope 53. The control shaft 541 on the control tube 54 slides along the spiral groove 562, causing the control shaft sleeve 561 to move closer to the state limit plate 63. That is, the lower end of the upright column 2 moves closer to the state limit plate 63, so that the locking protrusion 62 locks the locking groove 632. The lower end of the upright column 2 is locked to the side of the walking and running machine body 3.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
