Abstract
Description
Technical Field
[0001] This invention relates to the field of fitness equipment technology, and in particular to a fitness device with adjustable leg pads. Background Technology
[0002] There is a type of fitness machine where, during exercises like high back pulls and seated rows, the hands grip the handles while the legs are held down by leg pads. Typically, the leg pads are manually adjustable for height. This means that during the beginning, middle, and end of the workout, there are no extra hands to adjust the leg pad position; adjustments can only be made after the workout ends, resulting in a poor user experience. Furthermore, after the workout, because the hands are gripping the handles and the legs are held down, the body cannot straighten. To end the workout, the hands must be released, which can cause the weight plates to fall onto the machine, potentially damaging it.
[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention
[0004] In response to the problems mentioned in the background art, the present invention proposes a fitness device that automatically adjusts the leg pads by stepping on and lifting the left and right feet.
[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In some embodiments of this application, a fitness device is provided, comprising: frame; A ratchet assembly, which is rotatably connected to the frame; A leg pad holder is rotatably connected to the frame. The leg pad holder is provided with a leg pad and a limiting part. The limiting part is configured to cooperate with the ratchet assembly to lock the leg pad holder in a target position. The limiting part is also configured to disengage from the ratchet assembly to release the locking of the leg pad holder. A left linkage mechanism is provided, on which a left foot pedal is provided. The left linkage mechanism is rotatably disposed between the leg pad frame and the frame. The left linkage mechanism is configured to drive the leg pad frame to move downward when the left foot pedal is stepped down. The left linkage mechanism includes an elastic damping device, which is configured to apply a force to the left linkage mechanism to give the left linkage mechanism a tendency to drive the leg pad frame to move upward. A right linkage mechanism is provided, wherein a right foot pedal is provided on the right linkage mechanism, and the right linkage mechanism is rotatably disposed between the ratchet assembly and the frame. The right linkage mechanism is configured to drive the ratchet assembly to rotate and disengage from the limiting part when the right foot pedal is stepped down.
[0006] In some embodiments of this application, the ratchet assembly includes a ratchet frame and a ratchet, the ratchet is connected to the ratchet frame, and the ratchet frame is rotatably connected to the frame and the right linkage mechanism; The limiting part is a pull-out limiting pin, which is configured to engage with the ratchet.
[0007] In some embodiments of this application, the frame includes an extension frame, a sleeve is provided on the extension frame, a rotating shaft passes through the sleeve, and the rotating shaft is connected to the ratchet frame.
[0008] In some embodiments of this application, the leg pad frame includes a left leg pad frame, a right leg pad frame, and a connecting beam, the connecting beam being disposed between the left leg pad frame and the right leg pad frame; one end of the left leg pad frame is connected to one side of the extension frame, and the other opposite end is provided with a left leg pad; one end of the right leg pad frame is connected to the other opposite side of the extension frame, and the other opposite end is provided with a right leg pad; the connecting beam is provided with the limiting portion; the sleeve and the ratchet assembly are located between the left leg pad frame and the right leg pad frame, and the connecting beam is located on the side of the ratchet assembly opposite to the sleeve.
[0009] In some embodiments of this application, the left linkage mechanism includes a left linkage and a left footrest; the first end of the left linkage is rotatably connected to the leg pad frame, and the second end of the left linkage is rotatably connected to the first end of the left footrest; the left foot pedal is provided on the first end of the left footrest, and the second end of the left footrest is rotatably connected to the frame; the elastic damping device is disposed between the frame and the left footrest.
[0010] In some embodiments of this application, the right linkage mechanism includes a right linkage and a right foot pedal; the first end of the right linkage is rotatably connected to the ratchet assembly, and the second end of the right linkage is rotatably connected to the right foot pedal; the middle part of the right foot pedal is rotatably connected to the frame, and the second end of the right foot pedal is provided with the right foot pedal.
[0011] In some embodiments of this application, the leg pad holder has an automatic foot pedal adjustment mode. In this mode, the limiting part cooperates with the ratchet assembly. Stepping down on the left foot pedal causes the left linkage mechanism to drive the leg pad holder downward. Releasing the left foot pedal locks the leg pad holder in the target position. Stepping down on the right foot pedal causes the right linkage mechanism to drive the limiting part to disengage from the ratchet assembly, thereby causing the leg pad holder to move upward under the action of the left linkage mechanism.

[0014] In some embodiments of this application, the handheld training mechanism is one or more of a linkage swing mechanism and a pull rope.
[0015] Compared with the prior art, the advantages and positive effects of the present invention are: The fitness device of this application achieves automatic height adjustment of the leg pad frame through a limiting part, a ratchet assembly, a left linkage mechanism, and a right linkage mechanism. The leg pad is locked in the target position by the engagement between the limiting part and the ratchet assembly. The left linkage mechanism is rotatably mounted between the leg pad frame and the frame; stepping on the left pedal mounted on the left linkage mechanism allows the leg pad frame to move downwards. The right linkage mechanism is rotatably mounted between the ratchet assembly and the frame; stepping on the right pedal mounted on the right linkage mechanism causes the ratchet assembly to rotate and disengage from the limiting part, thereby allowing the elastic damping device to drive the leg pad frame upwards via the left linkage mechanism. In short, stepping on the left pedal with the left foot adjusts the leg pad position downwards, and stepping on the right pedal with the right foot releases the leg pad's limiting position; this adjustment-release-adjustment process can be repeated. By alternately stepping on the pedals with both feet, the height of the leg pad frame can be automatically adjusted without manual intervention.

[0026] In some embodiments of this application, a fitness device is provided. Figure 1 This is a structural diagram of a fitness machine viewed from the left. Figure 2 This is a side view of the fitness equipment viewed from the left. Figure 3 This is a structural diagram of a fitness machine viewed from the right. Figure 4 This is a side view of the fitness equipment viewed from the right. Figure 5 and Figure 6Top views of the fitness equipment in two different states. Figure 7 This is a cross-sectional view of a fitness machine. Figure 8 for Figure 7 Enlarged view of section A.
[0027] The fitness equipment consists of a frame 100, a ratchet assembly 200, a leg pad frame 300, a left linkage mechanism 400, a right linkage mechanism 500, a handheld training mechanism 600, and a seat 800.
[0028] The fitness equipment includes a frame 100. The frame 100 includes a horizontal frame and a vertical frame, which are fixedly connected. The horizontal frame is placed on the ground. The vertical frame is fixed to the upper part of the horizontal frame. The frame 100 serves as a mounting carrier for other components.
[0029] The fitness equipment includes a seat 800, which is fixedly connected to a horizontal frame. The height of the seat 800 is adjustable to accommodate users of different heights.
[0030] The fitness equipment includes a handheld training mechanism 600, which allows trainees to perform exercises such as back stretching and rowing.
[0031] The fitness equipment includes a leg pad frame 300, on which leg pads are installed. When the trainee 900 sits on the seat 800 to perform exercises such as back pulls and rows, the leg pads press down on the trainee's legs.
[0032] When trainees perform exercises such as high back pulls and seated rows, they pull on the handheld training mechanism 600 with both hands, while their legs are pressed down by the leg pads. In existing technology, the leg pads rely on manual height adjustment. Therefore, there are no extra hands available to adjust the leg pad position during the beginning, middle, and end of the exercise; adjustments can only be made after the exercise is finished, resulting in a poor experience. Furthermore, during high back pulls, because the hands are still gripping the handheld training mechanism 600 and the legs are pressed down by the leg pads, the body cannot stand upright. To end the exercise, the trainee must release their hands, causing the pull load to fall onto the frame 100, potentially damaging it.
[0033] In view of this, this application improves the position adjustment structure of the leg pad holder 300 to solve the above-mentioned technical problems.
[0034] The fitness equipment includes a ratchet assembly 200, which is rotatably connected to the frame 100, specifically, the ratchet assembly 200 is rotatably connected to the vertical frame. Figure 8 This is a cross-sectional view of the ratchet assembly 200.
[0035] The leg pad holder 300 is rotatably connected to the frame 100. A limiting part 700 is provided on the leg pad holder 300. The limiting part 700 is configured to cooperate with the ratchet assembly 200 to lock the leg pad holder 300 in a target position. Figure 5 The middle limiting part 700 engages with the ratchet assembly 200. The limiting part 700 is also configured to disengage from the ratchet assembly 200 to release the locking of the leg pad holder 300. Figure 6 The middle limit part 700 disengages from the ratchet assembly 200.
[0036] The fitness equipment includes a left linkage mechanism 400. (See reference) Figure 1 and Figure 2 A left foot pedal 430 is provided on the left linkage mechanism 400. The left linkage mechanism 400 is rotatably disposed between the leg pad frame 300 and the frame 100. The left linkage mechanism 400 is configured to drive the leg pad frame 300 downward when the left foot pedal 430 is pressed down, so as to adjust the position of the leg pad frame 300.
[0037] The left linkage 400 includes an elastic damping device 440, which is configured to apply a force to the left linkage 400 to induce the left linkage 400 to move the leg pad 300 upward. For example, the elastic damping device 440 is a gas spring.
[0038] The fitness equipment includes a right linkage mechanism 500. (See reference) Figure 3 and Figure 4 A right foot pedal 530 is provided on the right linkage mechanism 500. The right linkage mechanism 500 is rotatably disposed between the ratchet assembly 200 and the frame 100. The right linkage mechanism 500 is configured such that when the right foot pedal 530 is pressed down, it drives the ratchet assembly 200 to rotate and disengage from the limiting part 700.
[0039] In the fitness device of this application, the leg pads are locked in the target position by the engagement of the limiting part 700 and the ratchet assembly 200. When the height of the leg pads needs to be adjusted, it can be adjusted manually or automatically by alternating foot pedaling, so that the hands can continue to operate the handheld training mechanism 600.
[0040] Specifically, the leg pad holder 300 has a manual adjustment mode. In this mode, the limiting part 700 is manually pulled to disengage from the ratchet assembly 200. After adjusting the leg pad holder 300 up or down to the target position, the limiting part 700 is released. The limiting part 700 then engages with the ratchet assembly 200 to lock the leg pad holder 300 in the target position.
[0041] In other words, when adjusting the leg pad position manually, first manually pull the limiting part 700 to disengage the limiting part 700 from the ratchet assembly 200. At this time, the leg pad frame 300 is released from the limiting position. Under the action of external force, the leg pad frame 300 can rotate up and down around the frame 100. Therefore, lifting the leg pad frame 300 upwards can raise the leg pad position, and pressing the leg pad frame 300 downwards can lower the leg pad position. After the leg pad height is adjusted to the target position, press the limiting part 700 down to engage with the ratchet assembly 200, thereby locking the leg pad frame 300 in the target position.
[0042] The leg pad holder 300 has an automatic foot pedal adjustment mode. In this mode, the limiting part 700 cooperates with the ratchet assembly 200. Stepping down on the left foot pedal 430 causes the left linkage mechanism 400 to drive the leg pad holder 300 downward. Releasing the left foot pedal 430 locks the leg pad holder 300 in the target position. Stepping down on the right foot pedal 530 causes the right linkage mechanism 500 to drive the limiting part 700 to disengage from the ratchet assembly 200, thereby causing the leg pad holder 300 to move upward under the action of the left linkage mechanism 400.
[0043] In other words, when the leg pad position is automatically adjusted by alternating foot pedals, if you want to lower the leg pad position, simply press down on the left foot pedal 430. Since the teeth of the ratchet 220 face downwards, when you press down on the left foot pedal 430, the left linkage mechanism 400 moves with the left foot pedal 430, and the left linkage mechanism 400 drives the leg pad frame 300 to move downwards, thereby lowering the position of the leg pad frame 300. After reaching the target position, release the left foot pedal 430, and the leg pad frame 300 will be locked in the target position by the limiting part 700 and the ratchet assembly 200.
[0044] To raise the leg pad position, first press down on the right foot pedal 530. The right linkage mechanism 500 moves with the right foot pedal 530, driving the ratchet assembly 200 to rotate, disengaging the ratchet assembly 200 from the limiting part 700 and releasing the lock on the leg pad frame 300. At this time, under the action of the elastic damping device 440, the left linkage mechanism 400 drives the left leg pad frame 310 to move upward. After reaching the target position, release the right foot pedal 530, causing the ratchet assembly 200 to re-engage with the limiting part 700, thereby locking the leg pad frame 300 in the target position.
[0045] The fitness device of this application achieves automatic height adjustment of the leg pad frame 300 through a limiting part 700, a ratchet assembly 200, a left linkage mechanism 400, and a right linkage mechanism 500. The leg pad is locked in the target position by the engagement between the limiting part 700 and the ratchet assembly 200. The left linkage mechanism 400 is rotatably disposed between the leg pad frame 300 and the frame 100. By stepping on the left pedal mounted on the left linkage mechanism 400, the leg pad frame 300 can move downwards. The right linkage mechanism 500 is rotatably disposed between the ratchet assembly 200 and the frame 100. By stepping on the right pedal mounted on the right linkage mechanism 500, the ratchet assembly 200 rotates to disengage from the limiting part 700, thereby allowing the elastic damping device 440 to drive the leg pad frame 300 upwards via the left linkage mechanism 400. In short, stepping on the left pedal with your left foot adjusts the leg pad position downwards, while stepping on the right pedal with your right foot releases the leg pad limit. This adjustment process of adjusting and releasing can be repeated. By alternating between stepping on the pedals with both feet, the leg pad holder 300 can achieve automatic height adjustment without manual intervention.
[0046] When using this fitness equipment, the user pulls the handheld training mechanism 600 with both hands while performing exercises such as high back pulls and seated rows, with their legs held down by the leg pads. To adjust the position of the leg pads at the beginning, middle, or end of the workout, simply step on the pedals.
[0047] In other embodiments, the leg support 300 can also be a seat cushion support, and the height of the seat cushion support can be automatically adjusted by using the above-mentioned foot pedaling method, without the need for hand intervention.
[0048] In some embodiments of this application, reference is made to Figure 3 and Figure 8 The ratchet assembly 200 includes a ratchet carrier 210 and a ratchet 220, which are fixedly connected to the ratchet carrier 210, for example, by bolts. The ratchet carrier 210 is rotatably connected to the frame 100 and the right linkage mechanism 500. For example, refer to... Figure 8 The ratchet carrier 210 and the frame 100 are rotatably connected via a pivot 230. For example, refer to... Figure 4 The ratchet carrier 210 and the right linkage mechanism 500 are connected by a spherical rotation. The limiting part 700 is a pull-out limiting pin, which is configured to cooperate with the ratchet 220.
[0049] The ratchet assembly 200 consists of two parts: on the one hand, the ratchet frame 210 facilitates rotational connection with the frame 100; on the other hand, the ratchet 220 facilitates engagement with the pull-out limit pin. The structure is reliable and compact, and easy to assemble and process.
[0050] In some embodiments of this application, reference is made to Figure 4 and Figure 8The frame 100 includes an extension frame 110, a sleeve 120 is provided on the extension frame 110, a rotating shaft 230 is inserted inside the sleeve 120, and the rotating shaft 230 is connected to the ratchet frame 210.
[0051] The extension frame 110 extends toward the side where the seat 800 is located. A sleeve 120 is provided at the end of the extension frame 110 near the seat 800. The sleeve 120 is a hollow cylindrical structure with both the upper and lower ends open.
[0052] The ratchet carrier 210 includes an upper plate 211, a lower plate 212, and a vertical connecting plate 213. The upper plate 211 is located at the top of the sleeve 120 and is fixedly connected to the upper end of the rotating shaft 230 by screws or other means. The lower plate 212 is located at the bottom of the sleeve 120 and is fixedly connected to the lower end of the rotating shaft 230 by screws or other means. The vertical connecting plate 213 is fixedly disposed between the upper plate 211 and the lower plate 212, and is fixedly connected to the ratchet 220 by bolts or other means. The vertical connecting plate 213 is located beside the sleeve 120, and there is a gap between the vertical connecting plate 213 and the sleeve 120 to avoid hard friction between the vertical connecting plate 213 and the sleeve 120 when the ratchet carrier 210 rotates.
[0053] In some embodiments of this application, reference is made to Figure 6 The leg pad frame 300 includes a left leg pad frame 310, a right leg pad frame 320, and a connecting beam 330. Both the left leg pad frame 310 and the right leg pad frame 320 are elongated plate-like structures. The connecting beam 330 is fixedly installed between the left leg pad frame 310 and the right leg pad frame 320 by welding or other methods. The leg pad frame 300 has a U-shaped structure.
[0054] One end of the left leg pad bracket 310 is rotatably connected to one side of the extension frame 110 via a pin or similar means, with the rotation point denoted as P7. A left leg pad 340 is provided at the other opposite end of the left leg pad bracket 310. One end of the right leg pad bracket 320 is connected to the other opposite side of the extension frame 110 via a pin or similar means, with the rotation point denoted as P8. A right leg pad 350 is provided at the other opposite end of the right leg pad bracket 320.
[0055] A limiting part 700 is provided on the connecting beam 330. The sleeve 120 and the ratchet assembly 200 are located between the left leg pad 310 and the right leg pad 320, and the connecting beam 330 is located on the side of the ratchet assembly 200 away from the sleeve 120.
[0056] By designing the leg pad frame 300 as a U-shaped structure and incorporating the extension frame 110, the rotational connection between the leg pad frame 300 and the extension frame 110 is facilitated. Furthermore, the ratchet assembly 200 is positioned within the space enclosed by the U-shaped leg pad frame 300, while the limiting part 700 is mounted on the connecting beam 330, which facilitates the engagement between the limiting part 700 and the ratchet 220. The structural layout of the leg pad frame 300, extension frame 110, sleeve 120, ratchet assembly 200, and limiting part 700 is compact and conducive to achieving the desired structural function.
[0057] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The left linkage mechanism 400 includes a left linkage 410 and a left footrest 420. The left linkage 410 has a first end and a second end. The first end of the left linkage 410 is rotatably connected to the leg pad frame 300, specifically to the left leg pad frame 310, with the rotation point denoted as P1. The left footrest 420 has a first end and a second end, and the second end of the left linkage 410 is rotatably connected to the first end of the left footrest 420, with the rotation point denoted as P2. A left foot pedal 430 is provided on the first end of the left footrest 420. The second end of the left footrest 420 is rotatably connected to the frame 100, with the rotation point denoted as P3. An elastic damping device 440 is disposed between the frame 100 and the left footrest 420.
[0058] Reference Figure 3 and Figure 4 The right linkage mechanism 500 includes a right linkage 510 and a right foot pedal 520. The right linkage 510 has a first end and a second end. The first end of the right linkage 510 is rotatably connected to the ratchet assembly 200, specifically, the first end of the right linkage 510 is spherically rotatably connected to the ratchet carrier 210, with the rotation point denoted as P4. The right foot pedal 520 also has a first end and a second end. The second end of the right linkage 510 is rotatably connected to the first end of the right foot pedal 520, with the rotation point denoted as P5. The middle portion of the right foot pedal 520 is rotatably connected to the frame 100, with the rotation point denoted as P6. A right foot pedal 530 is provided at the second end of the right foot pedal 520.
[0059] The left linkage mechanism 400 and the right linkage mechanism 500 are positioned on opposite sides of the frame 100. Their movements do not interfere with each other, facilitating the rotational connection between the left linkage mechanism 400 and the leg pad frame 300, as well as the rotational connection between the right linkage mechanism 500 and the ratchet frame 210. Furthermore, the structure of the two linkage mechanisms, while meeting the requirements of force transmission, also perfectly avoids the trainee's legs, providing sufficient space for leg movement.
[0060] In some embodiments of this application, the fitness device further includes a handheld training mechanism 600, which is connected to the frame 100. The handheld training component is one or more of a linkage swing mechanism and a pull rope.
[0061] For example, the handheld training mechanism 600 is a linkage swing mechanism, refer to... Figure 1 The linkage swing mechanism is a scissor-type linkage mechanism, which allows trainees to perform back-pulling and other training exercises.
[0062] For example, the handheld training device 600 uses a pull rope, allowing trainees to perform rowing and other training exercises by pulling the rope.
[0063] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0064] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
