Description

Technical Field

[0001] This utility model relates to the technical field of sports equipment, specifically to a hanging ski training device. Background Technology

[0002] Traditional ski training equipment is a type of exercise equipment that simulates the arm movements during skiing, such as the ski machine disclosed in announcement number CN219701020U. This type of ski training equipment is bulky, with the baseboard requiring a large amount of ground space, and the frame needing a certain height. The entire frame is more than two meters long and tall, occupying a large amount of space with low space utilization. Furthermore, when it is necessary to change the training location, the entire ski training equipment is difficult and cumbersome to move.

[0003] In response, some have proposed an improved hanging ski trainer, including a damping disc and a traction unit. The traction unit comprises a rope, pulley system, and support frame. The pulley system is mounted on the support frame, with one end of the support frame located outside the damping disc and the other end inside. The rope is wound around the pulley system and ultimately connected to the damping component through the pulley system, elastic reset element, and support frame within the damping disc. Two traction units are arranged side-by-side to accommodate the trainee's arms. This necessitates increasing the thickness of the damping disc's outer frame to allow sufficient space inside for the rope, pulley system, and support frame. In other words, the entire damping disc needs modification to expand its internal capacity; existing commercially available damping discs cannot be directly used. Furthermore, in case of malfunction, the entire damping disc must be disassembled for repair and inspection, a cumbersome process. In addition, a portable fitness device disclosed in announcement number CN 212118881U can also function as a hanging ski training device, and its structure is basically the same as the aforementioned hanging ski training device.

[0004] Therefore, there is an urgent need to design a hanging ski training device that is small in size, has high space utilization, and is easy to maintain. Utility Model Content

[0048] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0050] Example 1:

[0051] Reference Figure 1-9 This embodiment provides a hanging ski training device, including a main frame 1, a rope reel 2, a damping disc 3, an elastic reset component 4, a pull rope 5, a pulley assembly 6, and an operating component 7. For ease of description, it is referred to as... Figure 1 The orientation of the main frame 1 of the ski training device when it is in a horizontal position is described.

[0052] Specifically, the main mounting frame 1 has a hollow main structure. In this embodiment, the main mounting frame 1 is roughly rectangular to facilitate the arrangement of other components within it. One end of the main mounting frame 1 along its length is a fixed end 11, which is detachably hooked and fixed. The other end is a cable outlet 12; the cable outlet 12 has a first cable outlet 13 for the pull rope 5 to pass through. The rope winding shaft 2 includes multiple winding zones 21 arranged sequentially along its axial direction. The damping disc 3 includes a disc body 32 and a drive shaft 31 disposed on the disc body 32. The disc body 32 is fixedly connected to the main mounting frame 1, and the drive shaft 31 is inserted into the hollow cavity of the main mounting frame 1, driving the rope winding shaft 2. An elastic reset member 4 is disposed in the hollow cavity of the main mounting frame 1 to provide a reset force to the rope winding shaft 2. The number of pull ropes 5 corresponds to the number of winding zones 21, and they are wound around different winding zones 21 respectively. At least a portion of the pulley assembly 6 is located at the cable outlet 12 of the mounting frame 1, for leading out the pull ropes 5 from different rope winding areas 21 respectively. The operating component 7 is connected to the end of the pull rope 5 for user operation.

[0053] The rope reel 2 is arranged inside the main mounting frame 1, and the damping disc 3 is driven and connected to the rope reel 2 and fixed outside the main mounting frame 1. The pull rope 5 and the elastic reset component 4 are arranged inside the main mounting frame 1 and connected to the rope reel 2, allowing the user to pull the pull rope 5 for movement. This design makes efficient use of the internal space of the main mounting frame 1 to achieve the movement operation function of the hanging ski trainer, and significantly reduces the space occupied by the hanging ski trainer, making it easy to install on walls or other external equipment, such as Smith machines. Furthermore, the damping disc 3 is located outside the main mounting frame 1 and is driven and connected to the rope reel 2 via the drive shaft 31. Therefore, there is no need to modify the damping disc 3, and the thickness of the existing damping disc 3 is not increased. When the damping disc 3 experiences a wiring failure, the existing damping disc 3 can be directly replaced, simplifying maintenance.

[0054] Furthermore, refer to Figure 1-4 In this embodiment, the rope winding area 21 on the rope winding shaft 2 is provided with two sections, and the pull rope 5 is provided with two sections accordingly. The hanging ski training device also includes an extension sub-frame 8, which is connected to the cable outlet 12 of the mounting main frame 1, and the extension sub-frame extends downward relative to the mounting main frame; the extension sub-frame 8 is provided with two second cable outlets 84 for the pull rope 5 to pass through, corresponding to the number of pull ropes 5.

[0055] Specifically, in this embodiment, the extension sub-frame 8 has a hollow inverted T-shaped structure. The extension sub-frame 8 includes an extension section 81 and a bifurcation section 82. One end of the extension section 81 is connected to the first cable outlet 13, and the other end is connected to the middle of the bifurcation section 82. Two second cable outlets 84 are respectively located at both ends of the bifurcation section 82 along its length. Two pull ropes 5 pass through the two second cable outlets 84 of the bifurcation section 82. By setting the extension sub-frame 8, the two pull ropes 5 can have sufficient distance at the exit positions of the second cable outlets 84 to accommodate the distance between the user's shoulders, allowing the user to perform more specific training movements. In other embodiments, the extension sub-frame 8 can also be designed as a hollow inverted V-shaped structure, such as... Figure 10 and Figure 11 As shown. The arrangement of the corresponding pulley assembly 6 needs to be adjusted according to the specific structure of the extension sub-frame 8. In contrast, the extension sub-frame 8 is designed as an inverted V-shaped structure, resulting in less space at the connection point with the main mounting frame 1, making it inconvenient to arrange the pulley assembly 6. The number of pulleys may need to be reduced accordingly, which could lead to uneven cable exit from the pull rope 5. In other embodiments, the extension sub-frame 8 can also be designed as a hollow inverted Y-shaped structure. However, if the extension sub-frame 8 is set as an inverted Y-shaped structure, with the extension section 81 remaining unchanged, if sufficient distance is required between the two second cable exits 84, then the extension sub-frame 8 needs to extend further downwards relative to the main mounting frame 1, thus occupying more space below the main mounting frame 1.

[0056] Meanwhile, the length L2 of the extension sub-frame 8 is less than the length L1 of the mounting main frame 1. In this embodiment, that is, the length of the bifurcation segment 82 is less than the length of the mounting main frame 1. This ensures that the overall size of the hanging ski trainer is not too large. When the fixed end 11 of the mounting main frame 1 is fixed, the extension sub-frame 8 extends downward, and the position of the second cable outlet 84 is below the position of the first cable outlet 13. In this way, the fixed end 11 can be fixed at a higher position, and the height of the second cable outlet 84 only needs to be adapted to the user, so that the entire hanging ski trainer further reduces interference with the user's activity area.

[0057] Furthermore, refer to Figure 8 and Figure 9The main frame 1 is equipped with a mounting base 14 at its fixed end 11 for fixing to a wall or other external equipment. The side wall where the fixed end 11 of the main frame 1 is located is inclined. The main frame 1 and the extension sub-frame 8 are configured such that when the side wall where the fixed end 11 is located is vertical, the main frame 1 is inclined upwards relative to the horizontal plane from the fixed end 11, and the extension sub-frame 8 extends downwards relative to the main frame 1. The extension sub-frame 8 can be inclined downwards or vertically downwards relative to the main frame 1; in this embodiment, the extension sub-frame 8 is substantially perpendicular to the main frame 1. That is, the pull rope 5 exits from the rope reel 2, is inclined upwards within the main frame 1, then inclined downwards after entering the extension sub-frame 8, and finally extends out from the second outlet 84. This allows the fixed end 11 of the main frame 1 to be fixed at a higher position, reducing the horizontal position of the damping disc 3 below the second outlet 84, thus reducing the space occupied by the entire hanging ski trainer below the second outlet 84 and improving space utilization. For example, for a training action that requires the second cable outlet 84 to be at a height of two meters, if the damping disc 3 is mostly below two meters in the horizontal direction, the hanging ski trainer would occupy a large amount of space below two meters. This space is primarily the trainee's training space, potentially interfering with the user's training control. In contrast, this embodiment reduces the portion of the damping disc 3 located below the second cable outlet 84 in the horizontal direction, making more efficient use of space and reducing interference with the trainee's training space. In this embodiment, the fixed end 11 is detachably equipped with a mounting base 14, which detachably secures the entire hanging ski trainer.

[0058] Furthermore, refer to Figure 4-6 The pulley assembly 6 has two sets of pulleys, each corresponding to a pull rope 5. The pulley assembly 6 includes a first pulley 61, a second pulley 62, and a third pulley 63. The two first pulleys 61 are spaced apart along the length of the bifurcation segment 82 at the outlet end 12 of the main frame 1, so that the two pull ropes 5 are spaced apart at the first outlet 13 along the length of the bifurcation segment 82. Two second pulleys 62 are correspondingly provided and spaced apart along the length of the bifurcation segment 82 at the point where the extension segment 81 connects to the bifurcation segment 82. Two third pulleys 63 are correspondingly provided and are respectively arranged at the second outlet 84 of the bifurcation segment 82. Each pull rope 5 passes sequentially around the corresponding first pulley 61, second pulley 62, and third pulley 63 before extending out of the corresponding second outlet 84. The first pulley 61 guides the pull rope 5 from the main frame 1 to the extension sub-frame 8. The second pulley 62 guides the pull rope 5 from the extension section 81 to the branch section 82. The third pulley 63 leads the pull rope 5 out from the second outlet 84. In this way, the pull rope 5 can be pulled smoothly.

[0059] Furthermore, rotating seats 83 are rotatably provided at both ends of the bifurcation segment 82. The axial direction of the rotating seats 83 is the same as the length direction of the bifurcation segment 82, and the second cable outlet 84 is arranged on the rotating seats 83. The axial direction of the third pulley 63 is perpendicular to the axial direction of the rotating seats 83. By setting the rotating seats 83, the third pulley 63 can rotate around the axial direction of the rotating seats 83 when the trainee pulls the rope 5 in different directions, thereby ensuring that the rope 5 can smoothly exit in different directions.

[0060] Furthermore, the main mounting frame 1 includes two mutually perpendicular length directions (X), width directions (Y), and height directions (Z). In this embodiment, the rope winding shaft 2 is configured such that when the main mounting frame 1 is placed horizontally, the axial direction of the rope winding shaft 2 is vertically aligned with the height direction of the main mounting frame 1, and the damping disc 3 is horizontally positioned. In this embodiment, the damping disc 3 is arranged on the lower end face of the main mounting frame 1 to facilitate adjustment of the damping magnitude.

[0061] Correspondingly, two first pulleys 61 are spaced apart at the cable outlet 12 of the main frame 1 along the width direction of the main frame 1, so that the cable outlet positions of the two pull ropes 5 at the first cable outlet 13 are spaced apart along the width direction of the main frame 1, thus avoiding interference between the cable outlets of the two pull ropes 5. Furthermore, the two first pulleys 61 are spaced apart along the height direction of the main frame 1, corresponding to the two winding areas 21 arranged axially along the rope winding shaft 2.

[0062] Furthermore, refer to Figure 7The elastic reset element 4 includes an elastic rope 41 and a winding wheel 42. Two elastic reset elements 4 are provided corresponding to the two winding areas 21. Each elastic reset element 4 corresponds to one of the two winding areas 21. Multiple winding wheels 42 are arranged on both sides of the inner wall of the main mounting frame 1 along its length, with each side's winding wheel 42 arranged axially along the winding shaft 2. One end of the elastic rope 41 is fixedly connected to the side wall of the main mounting frame 1, and the other end is fixedly connected to the winding shaft 2. The elastic rope 41 is wound around each winding wheel 42 so that the elastic rope 5 wound on each winding wheel 42 approximately forms a rectangular surface 43. The rectangular surface 43 has a gap from the winding shaft 2, and the direction of the elastic rope 41 between adjacent winding wheels 42 is approximately perpendicular to the axial direction of the winding shaft 2. It should be noted that this approximately rectangular surface 43 is generally rectangular, and irregularities at its edges and imperfections in the parallelism of opposite sides can be ignored. In this way, the space within the main frame 1 can be utilized efficiently, allowing the elastic rope 41 to be wound around multiple winding wheels 42. This provides sufficient elastic potential energy after stretching, enabling the elastic rope 41 to exert a restoring force on the winding shaft 2. Furthermore, the winding wheels 42 can be stacked along their own axial direction, i.e., two or more winding wheels 42 can be arranged on the same axis, allowing the elastic rope 41 to be wound around more winding wheels 42, providing sufficient restoring force to the winding shaft 2. In other embodiments, a single elastic restoring element 4 can be provided. However, if only one elastic restoring element 4 is provided, the elastic rope 41 needs to be stretched sufficiently, which can easily lead to fatigue and a short service life. Therefore, it is preferable to provide two elastic restoring elements 4, corresponding to the two winding areas 21.

[0063] Furthermore, the drive spindle 31 and the rope winding shaft 2 are coaxially arranged and detachably fixedly connected. In this embodiment, the drive spindle 31 is inserted into the rope winding shaft 2, and the two are fixedly connected for transmission. This arrangement simplifies the transmission method between the two and requires less space inside the main mounting frame 1. In other embodiments, the drive spindle 31 and the rope winding shaft 2 can also be connected by a belt pulley or gear transmission, but this arrangement requires more components to be arranged inside the main mounting frame 1, resulting in a more complex structure and a larger space occupation.

[0064] Furthermore, the length L1 of the main frame 1 is greater than or equal to the maximum outer diameter L3 of the damping disc 3 and less than twice the maximum outer diameter L3 of the damping disc 3. This significantly reduces the overall size of the hanging ski training device.

[0065] Furthermore, the hanging ski training device also includes a human-computer interaction device 9, specifically an electronic display. The electronic display can show information such as the number of repetitions, exercise time, and energy consumption. In this embodiment, a mounting rod 85 is hinged at the middle of the bifurcation segment 82. The hinge axis of the mounting rod 85 is parallel to the axis of the bifurcation segment 82, and the hinge axis between the mounting rod 85 and the bifurcation segment 82 has damping, thereby maintaining a constant angle between the mounting rod 85 and the bifurcation segment 82, and allowing external force to be applied to change the angle between them. The human-computer interaction device 9 is mounted on the mounting rod 85, so that the orientation of the human-computer interaction device 9 can be changed by pushing the mounting rod 85 according to different training scenarios.

[0066] Furthermore, the damping disc 3 has a flat cylindrical structure 32, which saves space. The damping disc directly adopts existing wind resistance damping discs or magnetic resistance damping discs on the market.

[0067] Furthermore, the operating component 7 is fixedly connected to the pull rope 5, or the operating component 7 and the pull rope are detachably connected via a hook. In this embodiment, the operating component 7 is a cylindrical handle structure, with its upper end fixed to the pull rope 5 and its lower end having an outwardly flared trumpet-shaped structure, so that the trainee's palm can grip the operating component 7. The outwardly flared trumpet-shaped structure at the lower end makes it difficult for the operating component 7 to detach from the palm when the palm applies force to the operating component 7 to pull the pull rope 5.

[0068] Example 2:

[0069] Reference Figure 12-14 The difference between this embodiment and Embodiment 1 is that:

[0070] The rope winding shaft 2 is configured such that when the main frame 1 is placed horizontally, the axial direction of the rope winding shaft 2 is the same as the width direction of the main frame 1 and is horizontally set, while the damping disc 3 is in a vertical position.

[0071] The number of first pulleys 61 corresponds to the number of pull ropes 5. Two first pulleys 61 are arranged at intervals along the width direction of the main frame 1 at the outlet end 12 of the main frame 1, so that the outlet positions of the two pull ropes 5 at the first outlet 13 are arranged at intervals along the width direction of the main frame 1.

[0072] Furthermore, the first pulley 61 is equipped with a hinge seat 611, which is installed at the cable outlet end 12 of the main frame 1, and the rotation axis of the hinge seat 611 is approximately perpendicular to the axis of the winding shaft 2. It should be noted that "approximately perpendicular" is about 90°, which can be 90° ± 10°. The first pulley 61 is configured such that when the pull rope 5 is pulled, as the cable outlet position of the pull rope 5 on the winding shaft 2 changes, the first pulley 61 can swing around the axis of the hinge seat 61, so that the cable entry direction of the pull rope 5 on the first pulley 61 is approximately perpendicular to the axial direction of the first pulley 61, ensuring that the pull rope 5 is smoothly pulled on the first pulley 61.
