[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The core of the present invention is to provide a climbing machine with multiple exercise modes.

[0042] For the specific embodiment of the climbing machine provided by the present invention, please refer to Figures 1 to 7, including a handle transmission assembly 2, a pedal transmission assembly 5, a first connecting member 7 and a second connecting member 8.

[0043] The handle transmission assembly 2 includes a first handle output portion 21 and a second handle output portion 22 with opposite movement directions. The first handle output portion 21 and the second handle output portion 22 are respectively connected to the handle 1. Figure 1 and Figure 7 As shown, the handle connected to the first handle output portion 21 is the left handle 11 , and the handle connected to the second handle output portion 22 is the right handle 12 .

[0044] The pedal transmission assembly 5 includes a first pedal output portion 51 and a second pedal output portion 52 with opposite movement directions. The first pedal output portion 51 and the second pedal output portion 52 are respectively connected to the pedal 4. Figure 1 and Figure 7 As shown, the pedal connected to the first pedal output portion 51 is the left pedal 41 , and the pedal connected to the second pedal output portion 52 is the right pedal 42 .

[0045] The first foot pedal output unit 51 is connected to the first handle output unit 21 via the first connector 7, and the second foot pedal output unit 52 is connected to the second handle output unit 22 via the second connector 8. The first handle output unit 21, the second handle output unit 22, the second connector 8, the second foot pedal output unit 52, the first foot pedal output unit 51, and the first connector 7 form a closed-loop transmission structure. Driven by the first connector 7, the first handle output unit 21 and the first foot pedal output unit 51 move in the same direction. Driven by the second connector 8, the second handle output unit 22 and the second foot pedal output unit 52 move in the same direction.

[0046] The positional relationship between the first connecting member 7 and the second connecting member 8 is adjustable, and the positional relationship specifically includes a parallel relationship and a cross relationship:

[0047] When the first connecting member 7 and the second connecting member 8 are in a parallel relationship, as shown in FIG. Figure 7 As shown, the first handle output unit 21 and the first pedal output unit 51 are located on the first side of the climbing machine, i.e., the left side in the figure, and the second handle output unit 22 and the second pedal output unit 52 are located on the second side of the climbing machine, i.e., the right side in the figure. At this time, since the left foot pedal 41 (actually located on the left) and the left handle 11 (actually located on the left) are at the same level, and the right foot pedal 42 (actually located on the right) and the right handle 12 (actually located on the right) are at the same level, for the user, since the left hand and right hand hold the left handle 11 and the right handle 12 in turn, and the left foot and right foot step on the left foot pedal 41 and the right foot pedal 42 in turn, the left hand and left foot move up and down simultaneously, and the right hand and right foot move up and down simultaneously, and are in the same hand and foot movement mode.

[0048] When the first connecting member 7 and the second connecting member 8 are in a cross relationship, the second handle output unit 22 and the first pedal output unit 51 are located on the first side of the climbing machine, i.e., the left side in the figure, and the first handle output unit 21 and the second pedal output unit 52 are located on the second side of the climbing machine, i.e., the right side in the figure. At this time, since the left pedal 41 (actually located on the left) is still at the same level as the left handle 11 (actually located on the right), and the right pedal 42 (actually located on the right) is still at the same level as the right handle 12 (actually located on the left), for the user, since the left hand and right hand hold the right handle 12 and the left handle 11 in turn, and the left foot and right foot step on the left pedal 41 and the right pedal 42 in turn, the user's left hand and right foot move up and down simultaneously, and the right hand and left foot move up and down simultaneously, and are in a cross motion mode.

[0049] In this embodiment, by adjusting the positional relationship between the first connecting member 7 and the second connecting member 8, the positional relationship between the handle 1 and the foot pedal 4 can be adaptively adjusted, so that the handle 1 and the foot pedal 4 located on the same side of the climbing machine can move in the same direction or opposite directions. The climbing machine can provide two modes of movement, which are easy to switch, can realize the diversification of exercise methods, and can improve the user experience.

[0050] Furthermore, the first connecting member 7 and the second connecting member 8 are respectively connected by steel cables. In this case, the first connecting member 7 and the second connecting member 8 are flexible structures, which facilitates the change of their positional relationship. Moreover, the use of steel cables is more durable. Of course, in other embodiments, the first connecting member 7 and the second connecting member 8 can also be connected by ropes or connecting rods.

[0051] The climbing machine further includes a footrest bracket 6 and a handle bracket 3. The handle 1 and handle transmission assembly 2 are mounted on the handle bracket 3, while the footrest 4 and foot transmission assembly 5 are mounted on the foot bracket 6. The handle bracket 3 is rotatably connected to the foot bracket 6. Rotation of the handle bracket 3 relative to the foot bracket 6 drives the first connecting member 7 and the second connecting member 8 to switch between a parallel relationship and a cross relationship, facilitating operation.

[0052] In addition, if Figure 1 As shown, the bottom end of the footrest bracket 6 is fixed on the base frame 64. The footrest bracket 6 can be tilted on the base frame 64. In order to improve the stability of the footrest bracket 6, a support frame 65 is also provided between the footrest bracket 6 and the base frame 64 so that the footrest bracket 6, the base frame 64 and the support frame 65 form a stable triangular support structure.

[0053] Furthermore, the handle transmission assembly 2 includes a handle shaft and a handle connector. The middle portion of the handle connector is wound around the handle shaft, and the two ends of the handle connector are respectively provided with a first handle output portion 21 and a second handle output portion 22. The first connector 7 and the second connector 8 are respectively connected to the two ends of the handle connector. Specifically, Figure 7As shown, the handle shaft is a handle pulley 23, the handle connecting member includes a handle steel cable 24, and the first connecting member 7 and the second connecting member 8 are respectively provided at both ends of the handle steel cable 24 to ensure the structural strength of the handle transmission assembly 2. Of course, in other embodiments, the handle transmission assembly 2 can also be a conveyor belt assembly.

[0054] In addition, the handle shaft is rotatably connected to the handle bracket 3 through the tensioning assembly, and the connection position of the tensioning assembly on the handle bracket 3 is adjustable, so that the tensioning degree of the first connecting member 7 and the second connecting member 8 can be adaptively adjusted.

[0055] Furthermore, if Figure 3 and Figure 5 As shown, the tensioning assembly includes a tensioning frame 32 and a tensioning bolt 33. The tensioning frame 32 is plugged into a strip-shaped adjustment hole 35 on the handlebar bracket 3. The adjustment hole 35 may extend in a direction close to the pedal bracket 6. The tensioning bolt 33 secures the tensioning frame 32 to the handlebar bracket 3 and can be fixed at any position within the adjustment hole 35. The handlebar shaft is rotatably connected to the tensioning frame 32. By fixing the tensioning frame 32 in the adjustment hole 35 and adjusting the distance between the handlebar shaft and the pedal bracket 6, the tensioning degree can be adjusted, providing convenient operation.

[0056] Furthermore, the pedal transmission assembly 5 includes a pedal shaft and a pedal connector. The middle portion of the pedal connector is wound around the pedal shaft, and a first pedal output portion 51 and a second pedal output portion 52 are respectively provided at the two ends of the pedal connector. The first connector 7 and the second connector 8 are respectively connected to the two ends of the pedal connector. Specifically, the pedal shaft includes a pedal shaft 55 rotatably connected to the pedal bracket 6 and a pedal timing pulley 53 fixed to the pedal shaft 55. The pedal connector includes a pedal timing belt 54 wound around the pedal timing pulley 53. The first pedal output portion 51 and the second pedal output portion 52 are respectively provided at the two ends of the pedal timing belt 54. Belt drive is used, which has a higher transmission stability. Of course, in other embodiments, the pedal transmission assembly 5 may also use a gear or rack transmission assembly.

[0057] In addition, the pedal shaft is rotatably connected to the pedal bracket 6, and a resistance portion is provided between the two, such as a wind resistance portion, a magnetic resistance portion, or a friction-enhancing portion, to increase the rotational resistance of the pedal shaft. When the pedal 4 is stepped on up and down, the pedal timing belt 54 is driven to move back and forth, thereby driving the pedal timing pulley 53 to rotate back and forth, and the pedal timing pulley 53 drives the pedal shaft 55 to rotate. The provision of the resistance portion increases the difficulty of exercise and enhances the training effect.

[0058] Furthermore, the first handle output part 21 and the second handle output part 22 are respectively handle sliding carts slidably connected to the handle bracket 3, and the first pedal output part 51 and the second pedal output part 52 are respectively pedal sliding carts slidably connected to the pedal bracket 6, which can reduce friction damage between the bracket and the corresponding output part.

[0059] Furthermore, a locking structure is provided between the handle bracket 3 and the pedal bracket 6 to lock the two after the handle bracket 3 rotates a set angle relative to the pedal bracket 6, thereby ensuring that the handle bracket 3 and the pedal bracket 6 can maintain their state after their positions are adjusted.

[0060] Wherein, optionally, Figure 2 and Figure 6 As shown, the locking structure includes a locating pin that simultaneously connects the handle bracket 3 and the footrest bracket 6 to lock both. This structure is simple and easy to manufacture. Specifically, the locating pin can be a fixed latch 34 that is slidably connected to the handle bracket 3. The footrest bracket 6 is provided with two receptacles 66. After the fixed latch 34 is aligned with the receptacles 66, the fixed latch 34 can be inserted into or out of the receptacles 66, thereby securing the handle bracket 3 relative to the footrest bracket 6 in two different motion modes, with the first connector 7 and the second connector 8 in a parallel and intersecting relationship, respectively.

[0061] Furthermore, a handle rotation limiting structure is provided on the handle bracket 3, and a pedal rotation limiting structure is provided on the pedal bracket 6, so that during the rotation of the handle bracket 3, the handle rotation limiting structure and the pedal rotation limiting structure offset each other and limit the rotatable angle of the handle bracket 3, thereby facilitating the positioning of the handle bracket 3.

[0062] Optionally, in this embodiment, the rotatable angle is 180°. When the handle bracket 3 is rotated relative to the footrest bracket 6 to one of the rotation limit positions, the climbing machine is in the synchronous mode. When the handle bracket 3 is rotated 180° to the other rotation limit position, the climbing machine is in the cross mode. This can also prevent the first connecting member 7 and the second connecting member 8 from twisting together due to excessive unidirectional rotation angle.

[0063] Furthermore, the handle bracket 3 is rotatably connected to the footrest bracket 6 via a bearing assembly to ensure smooth rotation. Specifically, a rotating shaft 31 is fixed to the bottom end of the handle bracket 3, and a ball bearing 62 is provided on the footrest bracket 6. The rotating shaft 31 is connected to the ball bearing 62 to achieve the rotational connection between the handle bracket 3 and the footrest bracket 6. In addition, a thrust bearing 63 can be connected between the handle bracket 3 and the footrest bracket 6 to prevent the ball bearing 62 from being squeezed and unable to rotate when the first and second connectors 7 and 8 are cross-tensioned.

[0064] The climbing machine in this embodiment has the advantage of convertible motion modes, which can realize diversified training methods, improve user experience, and make the exercise effect more obvious. Moreover, the conversion can be achieved by simply rotating the handle bracket 3, and the conversion operation is convenient and quick.

When an element is referred to as being "connected" to another element, it may be directly connected to the other element or there may be an intermediate element. In addition, in the description of the present invention, unless otherwise specified, "plurality," "plurality," and "plurality of groups" mean two or more.
