Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to a climbing stair machine. Background Technology

[0002] In existing technologies, climbing machines and stair climbers are mostly standalone devices with limited functionality and large space requirements. Users who want to perform stair climber training and simulated climbing training simultaneously need to purchase two separate devices, which not only consumes significant space but also increases user costs. Furthermore, single-function fitness equipment cannot meet the diverse fitness needs of users, limiting their training options. Therefore, developing a fitness device that integrates stair climber and climbing functions is of significant practical importance. Utility Model Content

[0003] To address the shortcomings of existing technologies, a climbing stair machine that integrates stair climbing and rock climbing functions is provided.

[0004] This utility model is achieved using the following technical solution: a rock climbing stair machine, comprising:

[0005] The main frame and the auxiliary frame are provided. The main frame is fixed with a left foot tube and a right foot tube. The slope between the main frame and the ground is adjustable, so that the main frame has a rock climbing slope or a stair climbing slope.

[0006] The left and right foot pedals, respectively, are slidably mounted on the left and right foot pedal tubes, and are configured to slide synchronously back and forth in a straight line along the left and right foot pedal tubes in opposite directions.

[0007] A left handle and a right handle are respectively connected to the left foot pedal and the right foot pedal. The left handle and the right handle extend along the length of the left foot pedal tube and the right foot pedal tube, and the left handle and the right handle are connected to the left foot pedal and the right foot pedal through a transmission assembly. The transmission assembly enables the left handle and the left foot pedal, and the right handle and the right foot pedal to move synchronously in the same direction or synchronously in opposite directions.

[0008] The stair climber's handle is located on the main frame.

[0009] Specifically, when the main frame is adjusted to the rock climbing slope, the user grips the left and right handles to conduct rock climbing simulation training; when the main frame is adjusted to the stair climbing slope, the user grips the stair climbing handles to conduct stair climbing training.

[0010] During use, the angle between the subframe and the main frame can be adjusted, thereby changing the angle between the main frame and the ground to create different slopes. Typically, a steeper slope is used for rock climbing, while a gentler slope is used for stair climbing, conforming to the ergonomics of both activities. This allows a single machine to be used for both rock climbing and stair climbing training, reducing space requirements and saving users money.

[0011] Furthermore, the angle of inclination of the human body is different when rock climbing and stair climbing; when rock climbing, the human body needs to be close to the rock wall, while when stair climbing, the upper body of the human body is in a vertical posture. Therefore, this solution provides left and right handles for people to hold when rock climbing and stair climbing handles for people to hold when stair climbing.

[0012] The configuration of the left and right foot pedals as reciprocating linearly in opposite directions along the left and right foot pedal tubes can be any existing configuration of a climbing machine, such as through the transmission of a traction rope and pulley, or through the transmission of gears and chains, etc.

[0013] Among them, "the transmission component enables the left handle and the left foot pedal, and the right handle and the right foot pedal to move synchronously in the same direction or synchronously in opposite directions." The same-direction movement can simulate the synchronous movement of the same hand and foot when rock climbing, while the opposite movement can simulate the movement of the same hand and foot moving closer or further apart when rock climbing.

[0014] Preferably, the stair climber handle is rotatably connected to the main frame, so that the stair climber handle can be in a working state for users to climb stairs or in a stored state that fits snugly against the main frame.

[0015] A switching component is provided between the stair climber handle and the main frame. The switching component is used to fix the position of the stair climber handle so that the stair climber handle is fixed in the use state or the storage state.

[0016] The stair climber handle has a switch between a working state and a storage state. When not in use, it can be stored away, or when stored away, the stair climber handle will avoid rock climbing, allowing users to use the device for rock climbing.

[0017] Preferably, the switching component includes a locking element and a first fixing piece and a second fixing piece disposed on the main frame; the first fixing piece and the second fixing piece are located on the rotation path of the stair climber handle and correspond to the positions of the stair climber handle in the use state and the storage state, respectively;

[0018] The stair climber handle is equipped with a locking component. The locking component passes through the first fixing plate or the second fixing plate and is fixed to the stair climber handle to fix the position of the stair climber handle.

[0019] The above-mentioned switching components are easy to operate and convenient for users.

[0020] Preferably, the stair climber includes a handle support rod and a handle portion located at the end of the handle support rod, and the length of the handle support rod is adjustable.

[0021] The length of the handle support is adjustable to suit people of different heights. The adjustable length of the handle support can be achieved by using any existing rod component length adjustment method, such as by setting inner and outer tubes, which are fixed together by buckles and multiple buckle holes, or by the inner and outer tubes being threaded together and the length is adjusted by a screw.

[0022] Preferably, both the left and right handles are provided with at least two grip portions spaced apart along their length.

[0023] Different grip sections are designed to accommodate people of different heights.

[0024] Preferably, the upper ends of the left and right handles have upwardly curved arc segments, and the grip portion is disposed on the arc segments.

[0025] The curved segment is more ergonomic.

[0026] Preferably, the subframe adopts a telescopic structure, and its length can be adjusted by telescoping to change the slope between the main support and the ground; or

[0027] The subframe is rotatably connected to the main frame, and by rotating the angle, the slope of the main support relative to the ground is changed; or

[0028] The subframe is a multi-section splicing structure. By splicing different numbers of sections or adjusting the splicing method, the length can be changed, thereby changing the slope between the main support and the ground.

[0029] The slope of the main frame is changed by the above settings.

[0030] As a preferred option, the climbing slope of the main frame is 35-60°, and the rock climbing slope of the main frame is 65-85°.

[0031] Among them, a slope of 50° is most suitable for climbing stairs, and a slope of 70° is most suitable for rock climbing.

[0032] Preferably, the transmission assembly enables the left and right handlebars and left and right foot pedals to move synchronously in the same direction;

[0033] The transmission assembly includes a connector that rigidly connects the handlebars to the left and right foot pedals, respectively.

[0034] Preferably, the transmission assembly enables the left and right handlebars and left and right foot pedals to move synchronously in opposite directions;

[0035] The transmission assembly includes a first rack and a second rack that are rigidly connected to the handlebars and foot pedals respectively. A gear is provided between the first rack and the second rack. The gear is rotatably fixed on the main frame and meshes with the first rack and the second rack.

[0036] Compared with the existing technology, the beneficial effects of this utility model are: the climbing stair machine in this solution integrates the functions of climbing stairs and rock climbing into one, meeting diverse fitness needs and reducing the user's purchase cost; it can also reduce space occupation, has low structural cost, high reliability, and flexible adjustment operation.

[0044] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] like Figures 1 to 5As shown in Embodiment 1, a climbing stair machine is disclosed, including a main frame 1 and a secondary frame 2. A stable triangular support structure is formed by the support between the main frame 1 and the secondary frame 2. Anti-slip pads 4 are provided at the bottom of both the main frame 1 and the secondary frame 2. A left foot pedal 32 and a right foot pedal 31 are fixedly mounted on the main frame, both extending along the length of the main frame 1. A left foot pedal 52 and a right foot pedal 51 are slidably mounted on the left foot pedal 32 and the right foot pedal 31, respectively. A pulley is provided on both the left foot pedal 52 and the right foot pedal 51, with an arc-shaped groove on the outer wall of the pulley. The walls of the left foot pedal 32 and the right foot pedal 31 contact and engage with the arc-shaped groove of the pulley, so that when the left foot pedal 52 and the right foot pedal 51 slide on the left foot pedal 32 and the right foot pedal 31, the pulley rolls on the left foot pedal 32 and the right foot pedal 31.

[0047] The left foot pedal tube 32 and the right foot pedal tube 31 are connected by an existing pulley assembly and a traction rope, so that the two slide in opposite synchronous reciprocating straight lines. When the left foot pedal tube 32 moves upward, the right foot pedal tube 31 moves downward; when the right foot pedal tube 31 moves upward, the left foot pedal tube 32 moves downward.

[0048] Left foot pedal 52 and right foot pedal 51 are respectively connected to left handlebar 72 and right handlebar 71. Left handlebar 72 and right handlebar 71 extend along the length of left foot pedal tube 32 and right foot pedal tube 31, respectively. The handles of left handlebar 72 and right handlebar 71 are connected to left foot pedal 52 and right foot pedal 51 via a transmission assembly. The transmission assembly is a connector 75 that rigidly connects the handles of left handlebar 72 and right handlebar 71 to left foot pedal 52 and right foot pedal 51, respectively. The connector 75 is existing sheet metal, and the handles of left handlebar 72 and right handlebar 71 are connected to left foot pedal 52 and right foot pedal 51 by welding or screw fixing. When left foot pedal 52 and right foot pedal 51 are pressed, left handlebar 72 and right handlebar 71 move synchronously and in the same direction as left foot pedal 52 and right foot pedal 51, respectively.

[0049] Both the left handle 72 and the right handle 71 are equipped with a set of rollers 11. The rollers 11 are rotatably fixed on the main frame 1. The rollers of the rollers 11 make rolling contact with the side walls of the left handle 72 and the right handle 71 to guide and position the movement of the rods.

[0050] The ends of the left handle 72 and the right handle 71 have upwardly curved arc segments 73, and each arc segment 73 is provided with three hand grips 74 spaced apart along the length of the arc segment 73.

[0051] The included angle between the main frame 1 and the secondary frame 2 is fixed. The length of the secondary frame 2 is adjustable. The secondary frame 2 includes an outer tube 21 and an inner tube 22, which are interlocked and slidably fitted together. The inner tube 22 has multiple stop holes. The outer tube 21 and the inner tube 22 are equipped with a pin 23. The pin 23 passes through one of the stop holes in the outer tube 21 and the inner tube 22, thus making the length of the entire secondary frame 2 adjustable. This allows for different slopes between the main frame 1 and the ground, ensuring that the main frame 1 has both a rock climbing slope and a stair climbing slope, with the rock climbing slope being steeper than the stair climbing slope. The stair climbing slope range is 35-60°, with 50° being most suitable, while the rock climbing slope range is 65-85°, with 70° being most suitable.

[0052] A stair-climbing handle 6 is also provided on the main frame 1. A first fixing plate 81 and a second fixing plate 82 are welded and fixed on the main frame 1. The stair-climbing handle 6 is rotatably connected to the first fixing plate 81. The first fixing plate 81 and the second fixing plate 82 are located on the rotation path of the stair-climbing handle 6 and correspond to the positions of the stair-climbing handle 6 in the use state and the storage state, respectively. The stair-climbing handle 6 is also equipped with a locking member 83, which is a conventional pin. The first fixing plate 81, the second fixing plate 82, and the stair-climbing handle 6 are all provided with locking holes through which the locking member 83 passes. When the locking member 83 passes through the first fixing plate 81 and the stair-climbing handle 6, the stair-climbing handle 6 is in the use state, that is, it extends in the vertical direction; when the locking member 83 passes through the second fixing plate 82 and the stair-climbing handle 6, the stair-climbing handle 6 is in the storage state, that is, the stair-climbing handle 6 is in contact with the main frame 1.

[0053] The stair-climbing handle 6 includes a handle support rod 61 and a handle portion 62 located at the end of the handle support rod 61. The length of the handle support rod 61 is adjustable, and the adjustment can be made using any existing rod-type component length adjustment method. For example, similar to the subframe 2 described above, it can also be adjusted by setting mutually fitted inner and outer tubes and using a pin to achieve gear adjustment.

[0054] In some other embodiments, the sub-frame 2 and the main frame 1 are connected by a rotatable connection, meaning the angle between the sub-frame 2 and the main frame 1 can be changed, thereby altering the slope of the main frame 1. Furthermore, a stop piece similar to the first fixing piece 81 can be installed between the sub-frame 2 and the main frame 1, and the sub-frame 2 is fixed at the adjusted angle via a pin engagement. (Not shown in the figure)

[0055] In some other embodiments, the sub-frame 2 is a multi-section spliced ​​structure. The length is changed by splicing different numbers of sections or adjusting the splicing method, thereby altering the slope of the main frame 1 relative to the ground. (Not shown in the figure)

[0056] Example 2

[0057] The difference between Embodiment 2 and Embodiment 1 is that: the left handle 72 and the right handle 71 are both rigidly connected to a first rack 91, and the left foot pedal 52 and the right foot pedal 51 are both rigidly connected to a second rack 92. A gear 93 is provided between the first rack 91 and the second rack 92. The gear 93 is rotatably fixed to the main frame 1, and the gear 93 meshes with the first rack 91 and the second rack 92, so that the left handle 72 and the right handle 71 move synchronously and in the opposite direction to the left foot pedal 52 and the right foot pedal 51. That is, when the left handle 72 rises, the left foot pedal 52 falls; when the left handle 72 falls, the left foot pedal 52 rises.
