Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, and in particular to a leg training device. Background Technology
[0002] It is known that for fitness equipment such as stair climbers that simulate mountain climbing, the exercise intensity on a stair climber is several times greater than that on a treadmill, and just five minutes a day can achieve the same amount of exercise as a full day. However, existing stair climbers (also called mountain climbers), such as the Chinese utility model patent with authorization announcement number CN221579602U, have a resistance mechanism on the support frame to increase the pedal resistance. The resistance mechanism includes a steel wire rope, with each end of the steel wire rope connected to two pedals. The steel wire rope is made of steel wire wound and woven. When one pedal moves downward, the other pedal is pulled upward by the steel wire rope, which has the effect of resetting the pedal. Two sets of deflecting wheels are connected to the steel wire rope. After the steel wire rope is turned by the deflecting wheels, it connects to the pedal on the other side. In the existing technology, only one steel wire rope is used, and the exercise load is the load of one steel wire rope. This is not suitable for some people with a higher body weight. Therefore, it is an urgent technical problem to be solved to increase the exercise load while maintaining an appropriate resistance. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0040] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A leg training device includes a support frame 1 and a support frame 2 intersecting with the support frame 1. The support frame 1, the support frame 2, and the support surface (generally the ground) form a triangle, which has good stability. The support frame 2 is equipped with a first pedal 3 and a second pedal 4 that move back and forth along the support frame 2. The first pedal 3 and the second pedal 4 move alternately on the support frame 2, thereby simulating stair climbing (mountain climbing) exercise. The support frame 2 is equipped with an upper pulley group 5 and a lower pulley group 6. An upper pull rope 7 connects the first pedal 3 and the second pedal 4 along the upper pulley group 5 on the support frame 2, and a lower pull rope 8 connects the first pedal 3 and the second pedal 4 along the lower pulley group 6 on the support frame 2. The first pedal 3 and the second pedal 4 are connected by an intermediate connecting rope assembly 9. It can be seen that this utility model increases the resistance of the device by using the upper pull rope 7 and the lower pull rope 8, increases the exercise load, and is more conducive to meeting the exercise needs of heavier people, making it more practical.
[0041] Example 2: This can be explained based on Example 1, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the upper pulley assembly 5 includes a mounting base 51 mounted on the support frame 2. At least two first fixed pulleys 52 are mounted on the mounting base 51. One end of the upper pull rope 7 is fixed to the first pedal 3, and the other end is fixed to the second pedal 4. The upper pull rope 7 moves through the first fixed pulleys 52. This arrangement facilitates the alternating up-and-down sliding of the first pedal 3 and the second pedal 4 along the support frame 2. In this embodiment, two first fixed pulleys 52 are used, both located inside the mounting base 51. This design further minimizes the obtrusiveness of the overall structure and allows for better alternating movement of the first pedal 3 and the second pedal 4 via the upper pull rope 7. The pulley block 6 includes at least two fixed seats 61 mounted on the support frame 2. Each fixed seat 61 has a second fixed pulley 62. One end of the pull-down rope 8 is fixed to the first pedal 3, and the other end is fixed to the second pedal 4. The pull-down rope 8 passes through each second fixed pulley 62. This arrangement facilitates the alternating up-and-down sliding of the first pedal 3 and the second pedal 4 along the support frame 2. In this embodiment, two fixed seats 61 and two fixed pulleys 62 are used, with one second fixed pulley 62 mounted on each fixed seat 61. This provides greater stability for the alternating up-and-down movement of the first pedal 3 and the second pedal 4 along the support frame 2. Therefore, this invention increases the resistance of the equipment and the exercise load by using the pull-up rope 7 and pull-down rope 8, making it more suitable for heavier users and more practical.
[0042] To further explain, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the intermediate connecting rope assembly 9 includes a first device seat 91 fixed on the first pedal 3 and a second device seat 92 fixed on the second pedal 4. The first device seat 91 is provided with a third fixed pulley 93, and the second device seat 92 is provided with a fourth fixed pulley 94. The first device seat 91 and the first pedal 3 are locked together by a first locking member 95, and the second device seat 92 and the second pedal 4 are locked together by a second locking member 96. The first locking member 95 and the second locking member 96 are connected by an intermediate pull rope 97. This arrangement facilitates the alternating up-and-down movement of the first pedal 3 and the second pedal 4 along the support frame 2. In this embodiment, two first locking members 95 and two second locking members 96 are used. One end of the intermediate pull rope 97 is connected to one of the first locking members 95, and the other end is connected to one of the second locking members 96, which facilitates implementation. Furthermore, both the first locking member 95 and the second locking member 96 are bolts or screws, facilitating installation and disassembly.
[0043] Example 3: This can be described based on Example 1 or Example 2, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the support frame 2 includes an upper fixed rod 21 mounted on the bracket 1, and a first support rod 22 and a second support rod 23 mounted on the upper fixed rod 21. The other end faces of the first support rod 22 and the second support rod 23 are connected by a lower fixed rod 24, which is used to place the frame on the ground. A first pedal 3 is mounted on the first support rod 22 and slides back and forth along the first support rod 22. A second pedal 4 is mounted on each of the second support rods 23 and slides back and forth along the second support rod 23. A first guide rail patch 25 is mounted on the first support rod 22 and a second guide rail patch 26 is mounted on the second support rod 23. This design helps to increase the smoothness of the first pedal 3 and the second pedal 4 on the first support rod 22 and the second support rod 23, and also reduces noise during use. To further explain, a shelf 27 is provided between the first support rod 22 and the second support rod 23. Items needed during exercise can be placed on the shelf 27. In this embodiment, the shelf 27 includes a base disposed between the first support rod 22 and the second support rod 23. The base is provided with a cup holder for placing a water cup. This is beneficial for placing items needed during exercise, such as water cups, and makes it easier to replenish water in a timely manner during exercise.
[0044] Among them, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a first damping component 28 for damping the first pedal 3 is located on the lower back of the first support rod 22, and a second damping component 29 for damping the second pedal 4 is located on the lower back of the second support rod 23. Both the first damping component 28 and the second damping component 29 are located on the back of the first support rod 22 and the second support rod 23. This arrangement not only effectively reduces noise and jerking during equipment use, but also appears more novel and aesthetically pleasing as it is not exposed on the front. Both the first damping component 28 and the second damping component 29 are mounted on a stabilizing seat on the lower fixed rod 24. The stabilizing seat is equipped with a locking element, which contains a rubber pad and a return spring. This composite damping arrangement is more conducive to effectively reducing noise and jerking during the sliding of the first pedal 3 and the second pedal 4, better meeting usage requirements and facilitating implementation.
[0045] Example 4: This can be described based on Example 1, Example 2, or Example 3, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the support 1 includes opposing support rods 11, with a connecting rod 12 connecting the lower ends of the opposing support rods 11. A first handrail 13 and a second handrail 14 are provided on the upper part of the opposing support rods 11. The first handrail 13 is located above the second handrail 14 and is broken in the middle. This double-layered handrail expands the user's height range and is also beneficial to the user. A waist twisting disc 15 is provided on the connecting rod 12. The waist twisting disc 15 helps to exercise the waist, hips and core muscles through left and right rotation or swaying movements. To further explain, at least one elastic rope 16 is provided on the connecting rod 12, and a shelf 17 for placing the elastic rope 16 is provided on the support rod 11. When in use, the elastic rope 16 is used for exercise, and when not in use, the upper end of the elastic rope 16 is placed on the shelf 17 to avoid clutter. In this example, the elastic rope 16 and the shelf 17 are arranged in pairs, which is conducive to better exercise. The elastic rope 16 stimulates muscles through elastic resistance, which is suitable for muscle building, shaping, strength improvement, coordination improvement and other needs.
[0046] The standard parts used in this application, such as elastic ropes and twisting discs, can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts and screws that are mature in the existing technology, and will not be described in detail here.
[0047] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
