[0064] The technical solutions in the embodiments of the present invention will be described clearly and comprehensively hereafter in combination with the accompanying drawings. It should be understood that the embodiments described here are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those skilled in this field based on these embodiments without creative efforts shall fall within the protection scope of the present invention.

[0065] As shown in FIGS. 1 and 5, this embodiment provides a mountain climbing machine, comprising:

[0066] a supporting frame assembly 1, comprising a first supporting frame 11 arranged in a front-back direction and configured for supporting on ground, and a second supporting frame 12 located on an upper side of the first supporting frame 11; a supporting surface 111 is arranged at a bottom of the first supporting frame 11 for supporting on the ground;

[0067] The mountain climbing machine has a usage state. When the mountain climbing machine is in use, a back end of the second supporting frame 12 is connected to the first supporting frame 11, and the second supporting frame 12 is gradually inclined upward from back to front. The second supporting frame 12 is equipped with two left and right parallel guiding members 122, and the second supporting frame 12 is further equipped with a winding pulley assembly 15. Each of the guiding members 122 is equipped with a pedal assembly 5 that slides on each of the guiding members 122, and a traction rope 6 that surrounds the winding pulley assembly 15 is connected between two sets of the pedal assembly 5;

[0068] a first locking assembly 13, arranged between the first supporting frame 11 and the second supporting frame 12 and configured for locking the second supporting frame 12 to the first supporting frame 11 in the usage state; and

[0069] an armrest frame assembly 2, arranged at a front side of supporting frame assembly 1 and extends towards above the second supporting frame 12 when in the usage state.

[0070] In some embodiments, as shown in FIG. 5, the mountain climbing machine further comprises a storage state. When the mountain climbing machine switches from the usage state to the storage state, the first locking assembly 13 releases the locking between the first supporting frame 11 and the second supporting frame 12, and both the second supporting frame 12 and the armrest frame assembly 2 are folded towards the first supporting frame 11, thereby reducing the space occupied by the entire mountain climbing machine in the storage state and facilitating storage or transportation. When the mountain climbing machine switches from the storage state to the usage state, both the second supporting frame 12 and the armrest frame assembly 2 are unfolded away from the first supporting frame 11, and the first locking assembly 13 locks the second supporting frame 12 to the first supporting frame 11 in the usage state, thereby making the entire mountain climbing machine more stable in use.

[0071] In some embodiments, the second supporting frame 12 comprises two guide rail frames 121 arranged in parallel and a connecting frame assembly 123 located between the two guide rail frames 121. The two guiding members 122 are respectively arranged on the two guide rail frames 121, and back ends of the two guide rail frames 121 are rotatably connected to the back end of the first supporting frame 11, specifically through a second rotating shaft 14. Specifically, the first supporting frame 11, the guide rail frames 121 and the connecting frame assembly 123 on the second supporting frame 12 can all be made of wood, thereby reducing costs. In contrast, the guiding members 122 can be formed as metal guide rails 122a.

[0072] As shown in FIGS. 1 and 8, as a specific implementation of the connecting frame assembly 123, the connecting frame assembly 123 comprises a first connecting frame 123a located between the front ends of the two guide rail frames 121 and a second connecting frame 123b located between the back ends of the two guide rail frames 121. The guide rail frame 121 can be fixedly connected to the first connecting frame 123a or the second connecting frame 123b through pins or other means, thereby making the entire structure of the second supporting frame 12 more stable.

[0073] As shown in FIGS. 1, 5, and 8, as a specific structure of the guide rail frames 121, each of the guide rail frames 121 comprises two clamping plates 121a arranged side by side and fixedly connected together. The guiding member 122 is a guide rail 122a set between the two clamping plates 121a, which can be fixedly connected by pins or other means to clamp the guide rail 122a between the two clamping plates 121a.

[0074] In some specific embodiments, as shown in FIGS. 1, 5, and 8, in order to improve the stability of the mountain climbing machine in the storage state, the first supporting frame 11 is provided with two first storage members 112 arranged in parallel on both sides of the first supporting frame 11;

[0075] When the mountain climbing machine switches from the usage state to the storage state, the two guide rail frames 121 are folded one by one into the two first storage members 112, respectively. Specifically, the connecting frame 123 located between the back ends of the two guide rail frames 121 is located between the back ends of the two first storage members 112.

[0076] As a specific implementation of the first storage member 112, as shown in FIGS. 1, 5, and 8, each of the first storage members 112 is formed as a first storage slot 112a extending in the front-back direction, and the back ends of the two guide rail frames 121 are respectively rotatably connected to the back ends of side walls of the two first storage slots 112a. When the mountain climbing machine switches from the usage state to the storage state, the two guide rail frames 121 are folded into the two first storage slots 112a one by one, respectively. Specifically, both left and right walls of the first storage slot 112a extend upward from a surface of the first supporting frame 11 and are fixedly connected or integrally formed with the first supporting frame 11. Therefore, when the mountain climbing machine switches to the storage state, the two guide rail frames 121 are folded into the two first storage slots 112a by rotating towards the first supporting frame 11. The first storage slot 112a limits the guide rail frames 121, making the guide rail frames 121 more stable in the storage state.

[0077] In some embodiments, as shown in FIGS. 1, 4, and 8, there are two sets of the first locking assemblies 13. Two sets of the first locking assemblies 13 are arranged in parallel on left and right sides of the second supporting frame 12. Each set of the first locking assemblies 13 comprises at least one first inserting hole 131 located on the first supporting frame 11, at least one second inserting hole 132 located on the second supporting frame 12, and a first pin 133. Specifically, the first inserting hole 131 is located on left and right walls of the corresponding first storage slot 112a. The second inserting hole 132 is located on the corresponding guide rail frame 121. When the mountain climbing machine is in use, the first pin 133 is inserted into the corresponding first inserting hole 131 and second inserting hole 132 for locking the second supporting frame 12 to the first supporting frame 11 in the usage state, which makes an angle of the second supporting frame 12 relative to the first supporting frame 11 more stable. And when there are multiple first or second holes 131 and 132, the first pin 133 can be inserted into the first and second holes 131 and 132 at different positions to adjust and lock a tilt angle of the second supporting frame 12.

[0078] In some specific embodiments, as shown in FIGS. 1, 5, and 8, in order to further fold the armrest frame assembly 2, two second storage members 113 are arranged in parallel on the first supporting frame 11. The armrest frame assembly 2 comprises two armrest frames 21 located on the left and right sides of the first supporting frame 11, and a second locking assembly 3 is arranged between each armrest frame 21 and the second supporting frame 12 for locking the armrest frame 21 and the second supporting frame 12 in the usage state.

[0079] The armrest frame 21 can be directly set above the front end of the second supporting frame 12, and can also be configured that each armrest frame 21 comprises an armrest member 211 located on an upper side and a supporting member 212 located on a lower side. A lower end of the supporting member 212 is detachably connected to the first supporting frame 11, and an upper end of the supporting member 212 is rotatably connected to a lower end of the corresponding armrest member 211. A third locking assembly 4 is provided between the supporting member 212 and the armrest member 211 to lock the supporting member 212 and the armrest member 211 in the usage state.

[0080] When the mountain climbing machine switches from the usage state to the storage state, the first locking assembly 13 releases the lock between the first supporting frame 11 and the second supporting frame 12, each set of the second locking assemblies 3 releases the corresponding lock between the armrest frame 21 and the second supporting frame 12, and each set of the third locking assemblies 4 releases the lock between the corresponding supporting member 212 and the armrest member 211. The lower end of each supporting member 212 is disassembled and separated from the first supporting frame 11, and the second supporting frame 12 rotates and folds towards the first supporting frame 11. Each armrest member 211 and its corresponding supporting member 212 rotate and fold towards each other. Each armrest member 211 and its corresponding supporting member 212 are further folded onto the corresponding second storage member 113. When the armrest member 211 and its corresponding supporting member 212 are folded together, the length of the entire armrest frame 21 decreases, thereby further reducing the space occupied by the storage state of the mountain climbing machine.

[0081] When the mountain climbing machine switches from the storage state to the usage state, each armrest frame 21 disengages from its corresponding second storage member 113, each armrest member 211 and its corresponding supporting member 212 rotate and unfold in a direction away from each other, and the second supporting frame 12 rotates and unfolds away from the first supporting frame 11. The lower end of each supporting member 212 is connected to the first supporting frame 11. Each set of the third locking assemblies 4 locks the corresponding supporting member 212 and armrest member 211 in the usage state, and each set of the second locking assemblies 3 locks the corresponding armrest frame 21 and the second supporting frame 12 in the usage state. The first locking assembly 13 locks the first supporting frame 11 and the second supporting frame 12 in the usage state, so as to make the structure of the entire mountain climbing machine more stable in use.

[0082] As a specific implementation of the second storage member 113, the second storage member 113 located on the left side is a first left L-shaped groove 113a located on the left side of the first supporting frame 11, and the second storage member 113 located on the right side is a first right L-shaped groove 113b located on the right side of the first supporting frame 11. A preferred structure is that the two first storage members 112 are located between the two second storage members 113. Specifically, the first left L-shaped groove 113a is formed by a left wall of the first storage groove 112a located on the left side of the first supporting frame 11 and an upper surface of the first supporting frame 11. The first right L-shaped groove 113b is specifically is formed by a right wall of the first storage groove 112a on the right side of the first supporting frame 11 and the upper surface of the first supporting frame 11.

[0083] As a specific implementation of the second locking assembly 3, as shown in FIGS. 3, 5, 6, and 8, the second locking assembly 3 comprises a first positioning pin 31 arranged between the armrest member 211 and the second supporting frame 12, and a second positioning pin 32 arranged between the supporting member 212 and the second supporting frame 12. When the mountain climbing machine is in use, the first positioning pin 31 is inserted into the armrest member 211 and the second supporting frame 12, and the second positioning pin 32 is inserted into the supporting member 212 and the second supporting frame 12, thereby making the connection between the armrest frame 21 and the second supporting frame 12 more stable.

[0084] The first implementation solution is that the first positioning pin 31 can be detachably set between the armrest member 211 and the second supporting frame 12, and the supporting member 212 is rotatably connected to the second positioning pin 32. When switching to the storage state, only the first positioning pin 31 and a locking pin 43 between a first connecting seat 41 and a second connecting seat 42 need to be removed, in this case the armrest member 211 can be moved towards the supporting member 212 by rotating around a third rotating shaft 22. After the lower end of the supporting member 212 separates from the first supporting frame 11, it can be folded by rotating around the second positioning pin 32. The supporting member 212 is connected to the second supporting frame 12 by rotating around the second positioning pin 32, which can prevent the two from detaching and make the armrest frame 21 more stable in the storage state;

[0085] Alternatively, the second implementation solution is that the second positioning pin 32 can be detachably arranged between the supporting member 212 and the second supporting frame 12, and the armrest member 211 is rotatably connected to the first positioning pin 31;

[0086] Alternatively, the third implementation solution is that the first positioning pin 31 can be detachably arranged between the armrest member 211 and the second supporting frame 12, and the second positioning pin 32 can be detachably arranged between the supporting member 212 and the second supporting frame 12. When switching to storage mode, both the first positioning pin 31 and the second positioning pin 32 are removed.

[0087] As a specific implementation of the third locking assembly 4, as shown in FIGS. 3, 5, 6, and 8, the third locking assembly 4 comprises a first connecting seat 41 located at the lower end of the armrest member 211 and a second connecting seat 42 located at the upper end of the supporting member 212. A back end of the first connecting seat 41 and a back end of the second connecting seat 42 are rotatably connected by a third rotating shaft 22. The second locking assembly 3 further comprises a locking pin 43 that can be detachably arranged between a front end of the first connecting seat 41 and a front end of the second connecting seat 42. When the mountain climbing machine is in use, the locking pin 43 is inserted into the front end of the first connecting seat 41 and the front end of the second connecting seat 42, thereby connecting the first connecting seat 41 and the second connecting seat 42 together, and thereby locking the armrest member 211 and the corresponding supporting member 212 in the usage.

[0088] As shown in FIGS. 1, 3, 5, and 8, as a specific implementation of the armrest member 211, the armrest member 211 comprises an armrest rod 211a and a grip rod 211b located at an upper end of the armrest rod 211a. The grip rod 211b and the armrest rod 211a form the L-shaped armrest member 211. When the mountain climbing machine is in the storage state, the two armrest rods 211a are respectively located on the two first storage members 112, and the two grip rods 211b are both located on the back side of the first supporting frame 11 and arranged in parallel, such as vertically or horizontally. A preferred solution is that the lower end of the armrest member 211 is inserted into the first connecting seat 41 and rotatably connected to the first connecting seat 41, so that when switching to the storage state, it is convenient to rotate the grip rod 211b on the armrest member 211 to the back side of the first supporting frame 11 by rotating the armrest member 211, thereby reducing its occupied space. And the armrest member 211 can rotate relative to the first connecting seat 41 to make the grip rod 211b face in different directions, making it easier for different users to adjust according to their needs and facilitate the grip of the grip rod 211b. Specifically, in usage state, the armrest member 211 is locked to the second supporting frame 12 through the first positioning pin 31 after rotation.

[0089] As a specific structure for the detachable connection between the supporting member 212 and the first supporting frame 11, two first inserting slots 114 are configured on the left and right sides of the first supporting frame 11, and the lower ends of the two supporting members 212 are correspondingly detachable and inserted into the two first inserting slots 114, respectively. The two first inserting slots 114 are respectively located on the left and right sides of the front end of the first supporting frame 11.

A front end of the pedal 51 is rotatably connected to the sliding seat 52 through a first rotating shaft 54, and an angle adjuster 53 is configured between the pedal 51 and the sliding seat 52. The angle adjuster 53 is configured for adjusting an inclination angle of the pedal 51 relative to the sliding seat 52, making it convenient for different users to use. Alternatively, when the mountain climbing machine switches to the storage state, the inclination angle of the pedal 51 relative to the sliding seat 52 can be adjusted to 0 degrees, which makes it occupy less space and convenient for storage.

[0091] As a specific structure of the angle adjuster 53, the angle adjuster 53 comprises several first positioning holes 531 arranged on the pedal 51 and surrounding the first rotating shaft 54, a second positioning hole 532 arranged on the sliding seat 52, and a first locking pin 533. The first locking pin 533 adjusts the inclination angle of the pedal 51 relative to the sliding seat 52 by coordinating different first positioning holes 531 with the second positioning hole 532.

[0092] The second supporting frame 12 is equipped with two parallel left and right guide holes 121b, with an extension direction of the guide holes 121b being parallel to a sliding direction of the sliding seat 52. Each sliding seat 52 is set on the corresponding guiding member 122 through three sets of sliding wheels 521, with two sets of sliding wheels 521 located on an upper side of the guiding member 122 and the other set of sliding wheels 521 located inside the guide holes 121b. Each set of sliding wheels 521 comprises two rollers arranged side by side and an axle arranged between the two rollers.

[0093] As a specific structure of the rope winding wheel assembly 15, the rope winding wheel assembly 15 comprises two rope winding wheels 151 arranged side by side. The two rope winding wheels 151 are respectively located at front ends of the two guide rail frames 121. The traction rope 6 is wound around the two rope winding wheels 151 and connected to two sliding seats 52 at both ends of the traction rope 6.Working Principle Explanation:

[0094] In usage state, the first locking assembly 13 locks the second supporting frame 12 to the first supporting frame 11, making the second supporting frame 12 more stable. The second locking assembly 3 locks the armrest frame 21 and the second supporting frame 12, and the third locking assembly 4 locks the armrest member 211 and the supporting member 212, making the connection between the armrest frame 21 and the second supporting frame 12 more stable. When in use, the user steps on two pedals 51 with both feet, driving the two pedals 51 to slide back and forth alternately along two guiding members 122, simulating the action of climbing mountains or stairs. When switching the mountain climbing machine to the storage state, the first locking assembly 13 releases the locking between the first supporting frame 11 and the second supporting frame 12, the second locking assembly 3 releases the locking between the armrest frame 21 and the second supporting frame 12, and the third locking assembly 4 releases the locking between the armrest member 211 and the supporting member 212, and the lower end of the supporting member 212 is detached from the first supporting frame 11, so as to facilitate the rotation of the armrest member 211 and the supporting member 212 to approach each other, and the second supporting frame 12 is rotated towards the first supporting frame 11 to switch the mountain climbing machine to the storage state.

[0074] In some specific embodiments, as shown in FIGS. 1, 5, and 8, in order to improve the stability of the mountain climbing machine in the storage state, the first supporting frame 11 is provided with two first storage members 112 arranged in parallel on both sides of the first supporting frame 11;

[0075] When the mountain climbing machine switches from the usage state to the storage state, the two guide rail frames 121 are folded one by one into the two first storage members 112, respectively. Specifically, the connecting frame 123 located between the back ends of the two guide rail frames 121 is located between the back ends of the two first storage members 112.

[0076] As a specific implementation of the first storage member 112, as shown in FIGS. 1, 5, and 8, each of the first storage members 112 is formed as a first storage slot 112a extending in the front-back direction, and the back ends of the two guide rail frames 121 are respectively rotatably connected to the back ends of side walls of the two first storage slots 112a. When the mountain climbing machine switches from the usage state to the storage state, the two guide rail frames 121 are folded into the two first storage slots 112a one by one, respectively. Specifically, both left and right walls of the first storage slot 112a extend upward from a surface of the first supporting frame 11 and are fixedly connected or integrally formed with the first supporting frame 11. Therefore, when the mountain climbing machine switches to the storage state, the two guide rail frames 121 are folded into the two first storage slots 112a by rotating towards the first supporting frame 11. The first storage slot 112a limits the guide rail frames 121, making the guide rail frames 121 more stable in the storage state.

[0077] In some embodiments, as shown in FIGS. 1, 4, and 8, there are two sets of the first locking assemblies 13. Two sets of the first locking assemblies 13 are arranged in parallel on left and right sides of the second supporting frame 12. Each set of the first locking assemblies 13 comprises at least one first inserting hole 131 located on the first supporting frame 11, at least one second inserting hole 132 located on the second supporting frame 12, and a first pin 133. Specifically, the first inserting hole 131 is located on left and right walls of the corresponding first storage slot 112a. The second inserting hole 132 is located on the corresponding guide rail frame 121. When the mountain climbing machine is in use, the first pin 133 is inserted into the corresponding first inserting hole 131 and second inserting hole 132 for locking the second supporting frame 12 to the first supporting frame 11 in the usage state, which makes an angle of the second supporting frame 12 relative to the first supporting frame 11 more stable. And when there are multiple first or second holes 131 and 132, the first pin 133 can be inserted into the first and second holes 131 and 132 at different positions to adjust and lock a tilt angle of the second supporting frame 12.

[0078] In some specific embodiments, as shown in FIGS. 1, 5, and 8, in order to further fold the armrest frame assembly 2, two second storage members 113 are arranged in parallel on the first supporting frame 11. The armrest frame assembly 2 comprises two armrest frames 21 located on the left and right sides of the first supporting frame 11, and a second locking assembly 3 is arranged between each armrest frame 21 and the second supporting frame 12 for locking the armrest frame 21 and the second supporting frame 12 in the usage state.

[0079] The armrest frame 21 can be directly set above the front end of the second supporting frame 12, and can also be configured that each armrest frame 21 comprises an armrest member 211 located on an upper side and a supporting member 212 located on a lower side. A lower end of the supporting member 212 is detachably connected to the first supporting frame 11, and an upper end of the supporting member 212 is rotatably connected to a lower end of the corresponding armrest member 211. A third locking assembly 4 is provided between the supporting member 212 and the armrest member 211 to lock the supporting member 212 and the armrest member 211 in the usage state.

[0080] When the mountain climbing machine switches from the usage state to the storage state, the first locking assembly 13 releases the lock between the first supporting frame 11 and the second supporting frame 12, each set of the second locking assemblies 3 releases the corresponding lock between the armrest frame 21 and the second supporting frame 12, and each set of the third locking assemblies 4 releases the lock between the corresponding supporting member 212 and the armrest member 211. The lower end of each supporting member 212 is disassembled and separated from the first supporting frame 11, and the second supporting frame 12 rotates and folds towards the first supporting frame 11. Each armrest member 211 and its corresponding supporting member 212 rotate and fold towards each other. Each armrest member 211 and its corresponding supporting member 212 are further folded onto the corresponding second storage member 113. When the armrest member 211 and its corresponding supporting member 212 are folded together, the length of the entire armrest frame 21 decreases, thereby further reducing the space occupied by the storage state of the mountain climbing machine.

[0081] When the mountain climbing machine switches from the storage state to the usage state, each armrest frame 21 disengages from its corresponding second storage member 113, each armrest member 211 and its corresponding supporting member 212 rotate and unfold in a direction away from each other, and the second supporting frame 12 rotates and unfolds away from the first supporting frame 11. The lower end of each supporting member 212 is connected to the first supporting frame 11. Each set of the third locking assemblies 4 locks the corresponding supporting member 212 and armrest member 211 in the usage state, and each set of the second locking assemblies 3 locks the corresponding armrest frame 21 and the second supporting frame 12 in the usage state. The first locking assembly 13 locks the first supporting frame 11 and the second supporting frame 12 in the usage state, so as to make the structure of the entire mountain climbing machine more stable in use.

When the mountain climbing machine is in use, the first positioning pin 31 is inserted into the armrest member 211 and the second supporting frame 12, and the second positioning pin 32 is inserted into the supporting member 212 and the second supporting frame 12, thereby making the connection between the armrest frame 21 and the second supporting frame 12 more stable.

[0084] The first implementation solution is that the first positioning pin 31 can be detachably set between the armrest member 211 and the second supporting frame 12, and the supporting member 212 is rotatably connected to the second positioning pin 32. When switching to the storage state, only the first positioning pin 31 and a locking pin 43 between a first connecting seat 41 and a second connecting seat 42 need to be removed, in this case the armrest member 211 can be moved towards the supporting member 212 by rotating around a third rotating shaft 22. After the lower end of the supporting member 212 separates from the first supporting frame 11, it can be folded by rotating around the second positioning pin 32. The supporting member 212 is connected to the second supporting frame 12 by rotating around the second positioning pin 32, which can prevent the two from detaching and make the armrest frame 21 more stable in the storage state;

[0085] Alternatively, the second implementation solution is that the second positioning pin 32 can be detachably arranged between the supporting member 212 and the second supporting frame 12, and the armrest member 211 is rotatably connected to the first positioning pin 31;

[0086] Alternatively, the third implementation solution is that the first positioning pin 31 can be detachably arranged between the armrest member 211 and the second supporting frame 12, and the second positioning pin 32 can be detachably arranged between the supporting member 212 and the second supporting frame 12. When switching to storage mode, both the first positioning pin 31 and the second positioning pin 32 are removed.

[0087] As a specific implementation of the third locking assembly 4, as shown in FIGS. 3, 5, 6, and 8, the third locking assembly 4 comprises a first connecting seat 41 located at the lower end of the armrest member 211 and a second connecting seat 42 located at the upper end of the supporting member 212. A back end of the first connecting seat 41 and a back end of the second connecting seat 42 are rotatably connected by a third rotating shaft 22. The second locking assembly 3 further comprises a locking pin 43 that can be detachably arranged between a front end of the first connecting seat 41 and a front end of the second connecting seat 42. When the mountain climbing machine is in use, the locking pin 43 is inserted into the front end of the first connecting seat 41 and the front end of the second connecting seat 42, thereby connecting the first connecting seat 41 and the second connecting seat 42 together, and thereby locking the armrest member 211 and the corresponding supporting member 212 in the usage.

[0088] As shown in FIGS. 1, 3, 5, and 8, as a specific implementation of the armrest member 211, the armrest member 211 comprises an armrest rod 211a and a grip rod 211b located at an upper end of the armrest rod 211a. The grip rod 211b and the armrest rod 211a form the L-shaped armrest member 211. When the mountain climbing machine is in the storage state, the two armrest rods 211a are respectively located on the two first storage members 112, and the two grip rods 211b are both located on the back side of the first supporting frame 11 and arranged in parallel, such as vertically or horizontally. A preferred solution is that the lower end of the armrest member 211 is inserted into the first connecting seat 41 and rotatably connected to the first connecting seat 41, so that when switching to the storage state, it is convenient to rotate the grip rod 211b on the armrest member 211 to the back side of the first supporting frame 11 by rotating the armrest member 211, thereby reducing its occupied space. And the armrest member 211 can rotate relative to the first connecting seat 41 to make the grip rod 211b face in different directions, making it easier for different users to adjust according to their needs and facilitate the grip of the grip rod 211b. Specifically, in usage state, the armrest member 211 is locked to the second supporting frame 12 through the first positioning pin 31 after rotation.
