First Embodiment

As shown in FIG. 1 to FIG. 6, FIG. 1 to FIG. 3 are schematic perspective views of a multi-functional chair in different angles according to an embodiment of the present disclosure, FIG. 4 is a schematic exploded view of the multi-functional chair according to the embodiment of the present disclosure, and FIG. 5 and FIG. 6 are schematic perspective views of an exercise kit of the multi-functional chair in different angles according to the embodiment of the present disclosure.

The multi-functional chair 100 of the present embodiment includes a seat body 1, a chair leg module 2, and an exercise kit 3. The seat body 1 is used for a user to be seated thereon. The seat body 1 can be provided with a soft object, such as a cushion and/or a backrest. The chair leg module 2 includes a chair leg 21 and a lifting component 22. The chair leg 21 can have a five-claw structure, but a quantity of claws of the chair leg 21 is not limited to five, and can be adjusted according to practical requirements. The chair leg 21 is provided with five casters 23 and five braking mechanisms 24, and each of the braking mechanisms 24 is operable by the user to restrict rotation of the casters 23. The lifting component 22 is connected to the seat body 1 and the chair leg 21, and the lifting component 22 is operable by the user to lift or lower the seat body 1 relative to the chair leg. The lifting component 22 can, for example, include a pneumatic rod.

It should be noted that each of the casters 23 of the chair leg 21 is connected to the braking mechanisms 24. Therefore, when the user uses the exercise kit 3 to exercise, the user can use each of the braking mechanisms 24 to prevent all the casters 23 from moving. Accordingly, the multi-functional chair 100 does not slide during exercise.

The seat body 1 and the chair leg module 2 referred to herein can be parts of conventional office chairs. The exercise kit 3 is detachably disposed under the seat body 1. In other words, the exercise kit 3 of the present embodiment is detachably mounted under the conventional office chair, and connected to the chair leg 21.

As shown in FIG. 2, FIG. 5, FIG. 6 and FIG. 7, the exercise kit 3 includes a fixing seat 31, five fixing members 32, a supporting structure 33, two springs 34, two damping rods 35, two pedal modules 36, and a plurality of hook components 37. In different embodiments, the exercise kit 3 can include none of the damping rods 35 and/or the hook components 37.

The fixing seat 31 includes a hollow sleeve 311 and a connecting plate 312. One end of the hollow sleeve 311 is configured to be sleeved on an outer side of the pneumatic rod of the lifting component 22. Another end of the hollow sleeve 311 is connected to the connecting plate 312. The connecting plate 312 is disposed at one side of the chair leg 21 facing toward the seat body 1.

As shown in FIG. 2, FIG. 4, FIG. 7, and FIG. 8, FIG. 7 is a schematic partially enlarged view of area VII of FIG. 2, and FIG. 8 is a schematic partially exploded view of FIG. 7. Each of the fixing members 32 includes an auxiliary fixing component 321 and a locking component 322. Multiple ones of the auxiliary fixing component 321 and multiple ones of the locking component 322 included in each of the fixing members 32 is not limited to a single one. The fixing seat 31 is disposed at one side of the chair leg 21 connected to the lifting component 22. Multiple ones of the auxiliary fixing component 321 are disposed at another side of the chair leg 21 opposite to the seat body 1, and multiple ones of the locking component 322 are configured to fix the multiple ones of the auxiliary fixing component 321 and the fixing seat 31 to each other. Accordingly, the fixing seat 31 and the multiple ones of the auxiliary fixing component 321 are jointly fixed to the chair leg 21.

More specifically, the connecting plate 312 can have five threaded holes 3121, each auxiliary fixing component 321 includes a through hole 3211, the auxiliary fixing component 321 includes an engaging structure 3212, such that the auxiliary fixing component 321 can be fixed to the chair leg 21 through the engaging structure 3212. Each locking component 322 can be, for example, a screw, and can pass through the through hole 3211 of the auxiliary fixing component 321 to fix to one of the threaded holes 3121 of the connecting plate 312. Therefore, the connecting plate 312 can be fixed to the side of the chair leg 21 facing toward the seat body 1, and the exercise kit 3 is fixed and disposed between the seat body 1 and the chair leg 21.

In the drawings of the present embodiment, the chair leg 21 includes the five claws, the exercise kit 3 includes the five fixing members 32, and the connecting plate 312 includes the five threaded holes 3121, but a quantity of the fixing members 32 included in the exercise kit 3 is not limited to five, and can be adjusted according to the quantity of the claws.

As described above, the exercise kit 3 is fixed to the side of the chair leg 21 facing toward the seat body 1 through the fixing seat 31 and the five fixing members 32. Therefore, in practical applications, the exercise kit 3 can be disposed under various types of sliding chairs (e.g., office chairs) by simply modifying the appearance of the fixing seat 31 and the fixing members 32. In other words, when the exercise kit 3 of the multi-functional chair 100 of the present embodiment is disassembled, the seat body 1 and the chair leg module 2 can be used as a general movable chair (e.g., an office chair). According to this design, when the exercise kit 3 needs to be repaired, the relevant maintenance personnel only needs to disassemble the exercise kit 3 from the chair leg module 2, so as to allow the user to continue using the movable chair.

As shown in FIG. 4 to FIG. 6, the supporting structure 33 is disposed at one side of the hollow sleeve 311. The supporting structure 33 can include a base 331, an extension arm 332, and a fixed arm 333. Two ends of the base 331 are respectively connected to the hollow sleeve 311 and the extension arm 332. The extension arm 332 can be an inclined structure formed by extending the base 331 in a direction away from the connecting plate 312. One end of the extension arm 332 opposite to another end of the extension arm 332 connected to the base 331 is connected to a middle position of the fixed arm 333. The fixed arm 333 can be, for example, an arc-shaped structure, and the two hook components 37 can be respectively disposed at two ends of the fixed arm 333. Each of the hook components 37 is configured to allow one end of an exercise resistance band to be attached thereto by the user.

One end of one of the damping rods 35 and one end of one of the springs 34 are fixed to the fixed arm 333, and can be disposed adjacent to one end of the fixed arm 333, while another end of the one of the damping rods 35 and another end of the one of the springs 34 are connected to one of the pedal modules 36. One end of another one of the damping rods 35 and one end of another one of the springs 34 are fixed to the fixed arm 333, and can be disposed adjacent to another end of the fixed arm 333, while another end of the another one of the damping rods 35 and another end of the another one of the springs 34 are connected to another one of the pedal modules 36. The two springs 34 can be respectively sleeved on the outer sides of the two damping rods 35.

As shown in FIG. 5, FIG. 6, FIG. 9, and FIG. 10, FIG. 9 is a side view of the multi-functional chair according to the embodiment of the present disclosure, and FIG. 10 is a schematic partially enlarged view of a pedal module of the multi-functional chair according to the embodiment of the present disclosure.

Each of the pedal modules 36 includes one of two rotating components, one of two connecting arms 364, one of two pedals 365 and one of two adjustment components 368. For the convenience of subsequent embodiment descriptions, the two rotating components respectively included in the two pedal modules 36 are respectively defined as a first rotating component 362 and a second rotating component 363. In the following description, if the description is in terms of the rotating components, then the description is applicable to both the first rotating component 362 and the second rotating component 363. If the description refers specifically to the first rotating component 362 or the second rotating component 363, then the description is only applicable to the first rotating component 362 or the second rotating component 363.

The rotating components are rotatably connected to the base 331 of the supporting structure 33. One end of each of the rotating components can be provided with one of the hook components 37. In practical applications, the base 331 can be provided with a plurality of ball bearings, and the one end of each of the rotating components is rotatably connected to the base 331 through one of the ball bearings.

One end of each of the connecting arms 364 is fixed to one of the rotating components, and each of the two pedals 365 is rotatably connected to another end of each of the connecting arms 364. Therefore, each of the pedals 365 is provided for the user sitting on the seat body 1 to step on the pedals 365.

As shown in FIG. 9 and FIG. 10, in practice, one end of each of the connecting arms 364 connected to the pedals 365 can be provided with a limiting component 3641, and each of the pedals 365 has a limiting structure 3651 (e.g., against top surface) corresponding to the limiting component 3641. The limiting component 3641 is used to restrict the rotation of the pedals 365 toward a direction of the chair leg 21, such that the pedals 365 and the connecting arms 364 can be substantially parallel to each other. With this design, when the user's feet are placed on the pedals 365, the pedals 365 do not rotate toward the direction of the chair leg 21, such that the user's feet are not flipped downwards. In other words, when the user steps on the pedals 365, the limiting structure 3651 of each of the pedals 365 is abutted against the limiting component 3641. Therefore, the pedals 365 do not rotate toward the direction of the chair leg 21.

As shown in FIG. 9, FIG. 10 and FIG. 11, when the user is sitting on the seat body 1, the user's feet can step on the two pedals 365 to rotate the two connecting arms 364 toward a direction away from the seat body 1. In this process, the two springs 34 are stretched, and an elastic recovery force generated by stretching of the two springs 34 provides resistance for the user to step thereon, so as to achieve the exercise effect for the user.

It is worth mentioning that, under normal circumstances, the two pedal modules 36 can move independently of each other, and the user can use the two pedal modules 36 to train each of the left foot or the right foot according to practical requirements. In other words, when the user's feet are placed on the two pedal modules 36, the user can train by treading. In different embodiments of the present disclosure, the two pedal modules 36 can also move simultaneously (details are described in subsequent embodiments).

As shown in FIG. 5, FIG. 6, FIG. 9, and FIG. 10, it should be noted that, in a better application, each of the connecting arms 364 can be provided with one of the adjustment components 368. Each of the adjustment components 368 includes one of two sliders 3681 and one of two spring pull pins 3682 (spring latch). Each of the sliders 3681 is slidably disposed at one of the connecting arms 364, and each of the spring pull pins 3682 is disposed on one of the sliders 3681. One end of each of the springs 34 and one end of each of the damping rods 35 are respectively fixed to one of the sliders 3681. The user can operate the spring pull pins 3682 to move the spring pull pins 3682 through the sliders 3681 to different positions on the connecting arms 364, and a bolt of each of the spring pull pins 3682 can be inserted into different through holes 3642 of the connecting arms 364, thereby changing a position of the one end of the springs 34 connected to one of the connecting arms 364. Therefore, when the user steps on the pedals 365, the user can experience varying levels of resistance provided by the spring 34.

It is worth mentioning that, in practice, one side of each of the pedals 365 facing toward the chair leg 21 can be further provided with an elastic abutting component 367. When each of the pedals 365 is stepped on by the user and rotates towards the direction of the chair leg 21, the elastic abutting component 367 is used to abut against the chair leg 21, thereby preventing the pedal modules 36 from causing damage to the chair leg 21.

As shown in FIG. 11, when the user steps the pedals 365 downward to its farthest position from the seat body 1 and then removes their feet from the pedals 365, the elastic recovery force of the two springs 34 drives the connecting arms 364 to move in a direction towards the seat body 1. During the process of the connecting arms 364 moving toward the seat body 1, each of the damping rods 35 connected to one of the connecting arms 364 provides resistance. Accordingly, the two pedal modules 36 can slowly move in the direction towards the seat body 1.

As described above, through the design of the damping rods 35, when the two pedal modules 36 move in the direction towards the seat body 1, an issue of the user's feet being caught by the two pedal modules 36 can be effectively prevented.

As shown in FIG. 3, FIG. 5, FIG. 6, and FIG. 9, in practice, two sides of the base 331 of the supporting structure 33 respectively have two block components 38. Each of the block components 38 is configured to abut against one of the connecting arms 364, such that a gap G is formed between the pedals 365 and the seat body 1. In other words, when the two pedal modules 36 are not being stepped on by the user, each of the connecting arms 364 abuts against the adjacent one of the block components 38, and each of the pedals 365 does not abut against the seat body 1, thereby preventing the user's feet from being caught.

In other words, when the user no longer steps on the two pedal modules 36, the two pedal modules 36 are driven by the two springs 34 and the two damping rods 35, and slowly move toward the direction of the seat body 1 until the two connecting arms 364 abut against the two block components 38 adjacent thereto. When the two connecting arms 364 abut against the two block components 38, the gap G is formed between the two pedals 365 and the seat body 1.

As shown in FIG. 9 to FIG. 13, FIG. 12 is a side view of the pedal of the multi-functional chair located in a retracted position according to the embodiment of the present disclosure. Each of the connecting arms 364 adjacent to the pedals 365 can also be provided with an auxiliary handle 39. The auxiliary handle 39 is configured to provide for the user to grip, such that the user can grip the auxiliary handle 39 to rotate the connecting arms 364 toward a direction away from the seat body 1.

In practice, each of the pedals 365 is rotatably connected to one of the connecting arms 364, and each of the pedals 365 is operable to rotate relative to the connecting arms 364 between a moving position (as shown in FIG. 9) and a retracted position (as shown in FIG. 12). When the pedals 365 are located at the moving position, the pedals 365 is configured to be stepped on by the user sitting on the seat body 1.

When the user no longer steps on the pedals 365, the two pedals 365 are returned to the moving position as shown in FIG. 9. At this time, the user can grip the auxiliary handle 39 to rotate the connecting arms 364 toward the direction away from the seat body 1 to increase the space of the gap G between the pedals 365 and the seat body 1. Then, the user can pull the pedals 365 to rotate toward the supporting structure 33, thereby switching the pedals 365 from the moving position to the retracted position (as shown in FIG. 12). When the pedals 365 are located at the retracted position, the pedals 365 are located under the seat body 1, and the pedals 365 do not protrude from a front edge of the seat body 1. Accordingly, the pedals 365 do not affect the normal use of the chair.

As described above, through the design of the outer sides of each of the connecting arms 364 being provided with the auxiliary handle 39 in combination with the design of the block components 38, the user can switch the pedals 365 from the moving position to the retracted position without the risk of pinching their hands.

It is worth mentioning that, the exercise kit 3 is fixed to the chair leg 21. Therefore, when the user operates the lifting component 22 to lift the seat body 1 in a direction away from the chair leg 21, the exercise kit 3 does not move with the seat body 1. In other words, the seat body 1 is also moved away from the exercise kit 3 at the same time. Accordingly, when the user switches the pedals 365 from the moving position to the retracted position, the user can first operate the lifting component 22 to move the seat body 1 in a direction away from the two pedal modules 36, and operate the pedals 365 to rotate the pedals 365 inward to switch the pedals 365 to the retracted position. In this way, the user can rotate the pedals 365 to the retracted position more conveniently.

As shown in FIG. 5, FIG. 6, FIG. 13, and FIG. 14, FIG. 13 is a rear side view of the multi-functional chair according to the embodiment of the present disclosure, and FIG. 14 is a schematic partially cross-sectional view of a synchronous member, a first rotating component, and a second rotating component of the multi-functional chair according to the embodiment of the present disclosure.

In practice, the first rotating component 362 and the second rotating component 363 are respectively disposed at the two sides of the supporting structure 33. The first rotating component 362 and the second rotating component 363 are located on an axis, such that the first rotating component 362 and the second rotating component 363 can rotate respectively with the same axis as the center relative to the supporting structure 33. The first rotating component 362 and the second rotating component 363 can each be a hollow tube.

The exercise kit 3 further includes a synchronous member 40. The synchronous member 40 includes a linkage rod 401 and a locking component 402. One end of the linkage rod 401 is fixed to the first rotating component 362, and the linkage rod 401 is also connected to a first ball bearing 41 and a second ball bearing 42 disposed in the base 331, such that the linkage rod 401 can rotate relative to the base 331 along with the first rotating component 362. The first ball bearing 41 and the second ball bearing 42 are respectively disposed at two sides of the base 331. One end of the first rotating component 362 and one end of the second rotating component 363 are respectively connected to the first ball bearing 41 and the second ball bearing 42, such that the first rotating component 362 and the second rotating component 363 can rotate relative to the base 331 through the first ball bearing 41 and the second ball bearing 42.

Another end of the linkage rod 401 is disposed in the second rotating component 363. When the synchronous member 40 does not connect the linkage rod 401 to the second rotating component 363, the linkage rod 401 can rotate with the first rotating component 362 in the second rotating component 363.

The second rotating component 363 includes a through hole 3631. The linkage rod 401 includes a threaded hole 4011. The locking component 402 includes a main body 4021, a manipulating portion 4022, and a locking structure 4023. The main body 4021 is fixed around the through hole 3631 of the second rotating component 363, the manipulating portion 4022 is rotatably connected to the main body 4021, the manipulating portion 4022 is fixed to the locking structure 4023, and one end of the locking structure 4023 has screw threads.

The user can rotate the manipulating portion 4022 to extend one end of the locking structure 4023 through the through hole 3631 of the second rotating component 363 into the second rotating component 363, and the locking structure 4023 is locked with the threaded hole 4011 of the linkage rod 401. In contrast, the user can rotate the manipulating portion 4022 to move the end of the locking structure 4023 away from the threaded hole 4011 of linkage rod 401.

The difference between this embodiment and the previous embodiment is that each of the two pedal modules 36 includes one of two rotating components 361, one of two connecting arms 364, one of two pedals 365, and one of two adjust modules 366. The rotating components 361 are rotatably connected to the base 331 of the supporting structure 33. One end of each of the rotating components 361 can further be provided with one of two hook components 37. In practice, the base 331 can be provided with a ball bearing, and one end of each of the rotating components 361 can be rotatably connected to the base 331 through the ball bearing.

Each of the adjust modules 366 includes a manipulating component 3661, a sliding component 3662, a first limiting structure 3643, and a second limiting structure 3663. The manipulating component 3661 is rotatably disposed on one of the connecting arms 364. The manipulating component 3661 includes a linkage rotating component 36611 and a linkage rod 36612. The linkage rotating component 36611 includes a body 366111 and a grip portion 366112. The body 366111 is, for example, a disk-shaped. One of the connecting arms 364 is, for example, a hollow structure, and the body 366111 and the linkage rod 36612 can be disposed in one of the connecting arms 364. The body 366111 of the linkage rotating component 36611 is rotatably disposed at one of the connecting arms 364, and one end of the linkage rod 36612 is pivotally connected to the linkage rotating component 36611. The grip portion 366112 is connected to the body 366111, and the grip portion 366112 is disposed at an outside of one of the connecting arms 364, such that the grip portion 366112 is operable by user.

The sliding component 3662 includes a slider 36621 and two pipe plugs 36622. The slider 3662 is, for example, a hollow structure, the slider 36621 is sleeved on one of the connecting arms 364, and the slider 36621 can slide relative to one of the connecting arms 364. The two pipe plugs 36622 are respectively disposed at two ends of the slider 36621, a part of each of the two pipe plugs 36622 is used to fill a gap between the slider 36621 and one of the connecting arms 364. The two pipe plugs 36622 are used to increase the friction between the slider 36621 and one of the connecting arms 364, and the two pipe plugs 36622 can be used to assist in limiting a range of movement of the slider 36621 relative to one of the connecting arms 364. When the slider 36621 is not acted upon by an external force, the slider 36621 is not moved relative to one of the connecting arms 364 due to the arrangement of the two pipe plugs 36622. Conversely, when the slider 36621 is acted upon by the externa force, the slider 36621 and the two pipe plugs 36622 are moved together relative to one of the connecting arms 364.

The slider 36621 is fixed to one end of one of the two springs 34, and the slider 36621 is connected to the another end of the linkage rod 36612. When one of the connecting arms 364 is the hollow structure, the slider 36621 is fixed to another end of the linkage rod 36612 through the connector 36623. The connector 36623 includes, for example, a screw rod and a nut.

The first limiting structure 3643 is disposed on one of the connecting arms 364 and adjacent to the slider 36621. The first limiting structure 3643 is, for example, an elongated through hole, the elongated through hole is form from one of the connecting arms 364, a part of the connector 36623 is through the elongated through hole. When the connector 36623 is against to one end of the elongated through hole, the connector 36623 is abutting against a side wall formed the elongated through hole, such that the movement range of the slider 36621 connected to the connector 36623 is be limited. The first limiting structure 3643 is mainly used to limit a movement range of the linkage rod 36612 relative to one of the connecting arms 364, such that a length of the elongated through hole can be adjusted according to practical requirements.

The second limiting structure 3663 is fixed and disposed on the body 366111 of the linkage rotating component 36611, the second limiting structure 3663 and the linkage rod 36612 are fixed to a same side of the body 36611 of the linkage rotating component 36611, and the second limiting structure 3663 is, for example, a protruding structure (e.g., protruding pillar). The second limiting structure 3663 is mainly used to limit a rotation range of the linkage rod 36612 relative to a rotation range of one of the connecting arms 364, such that as long as a position provided the second limit structure 3663 can be used to limit the rotation range of the connecting rod 36612, and the appearance and the position of the second limiting structure 3663 can be adjusted according to practical requirements. In other words, in different embodiments, the second limiting structure 3663 can disposed on the connection arm 364.

As shown in FIG. 3 to FIG. 5, when the linkage rotating component 3661 is located at a first position, the second limiting structure 3663 is not in contact with one end of the linkage rod 36612, such that the user can grip the grip portion 366112 and rotate the grip portion 366112 along a first rotation direction R1.

At the same time, the connector 36623 is disposed adjacent to the second limiting structure 3663. When the user rotates the grip portion 366112 along a second rotation direction R2, the connector 36623 is abutting against an inner wall of the elongated through hole, such that the movement range of the connector 36623 is limited, and the slider 36621 cannot move relative to one of the connecting arms 364. The second rotation direction R2 is the reverse direction of the first rotation direction R1. In other words, in the situations shown in FIG. 3 to FIG. 5, when the user rotates the grip portion 366112 to rotate along the second rotation direction R2, the connector 36623 is abutting against the inner wall of the elongated through hole, and the user is clearly feel that the grip portion 366112 is difficult to rotate along the second rotation direction R2.

Conversely, in the situations shown in FIG. 3 to FIG. 5, when the user rotates the grip portion 366112 along the first rotation direction R1, the linkage rotating component 36611 drives the linkage rod 36612 to rotate, and the linkage rod 36612 drives the slider 36621 to slide toward one of the pedals 365 along a first direction L1 relative to one of the connecting arms 364.

As shown in FIG. 17 and FIG. 20 to FIG. 22, FIG. 20 is a schematic partially view showing the slider of the exercise kit located at a second slider position of the multi-functional chair according to the second embodiment of the present disclosure; FIG. 21 is a schematic partially cross-sectional view showing the slider of the exercise kit located at the second slider position of the multi-functional chair according to the second embodiment of the present disclosure; and FIG. 22 is a schematic partially bottom and cross-sectional view showing the slider of the exercise kit located at the second slider position of the multi-functional chair according to the second embodiment of the present disclosure.

As shown in FIG. 3, when the grip portion 366112 is operated by the user to rotate along the first rotation direction R1 and converted to the state shown in FIG. 6, the linkage rotating component 36611 is rotated from a first position shown in FIG. 4 and FIG. 5, to a second position shown in FIG. 7 and FIG. 8, and the linkage rod 36612 is rotated with the linkage rotating component 36611, such that one side of the linkage rod 36612 is abutting to the second limiting structure 3663. At the same time, the slider 36621 is moved from a first slider position shown in FIG. 3 to the second slider position shown in FIG. 6.

In the situations shown in FIG. 6 to FIG. 8, when the user rotates the grip portion 366112 to rotate along the first rotation direction R1, the linkage rod 36612 is abutting against the second limiting structure 3663, and the user is clearly feeling that the grip portion 366112 is difficult to rotate along the first rotation direction R1.

As mentioned above, as shown in FIG. 3 and FIG. 6, the user can simply grip and rotate the grip portion 366112 to move the slider 36621 between the first slider position shown in FIG. 3 and the second slider position shown in FIG. 6, thereby changing the position of one end of one of the two springs 34 can change the amount of resistance obtained by the user after stepping on the pedals 365. In addition, through the design of the first limiting structure 3643 and the second limiting structure 3663, the user can clearly know that the grip portion 366112 has reached a specific position and can no longer be rotated.

It is worth mentioning that since the slider 36621 is provided with the two pipe plugs 36622, no matter the slider 36621 is located at the first slider position or the second slider position, when the user steps on the pedals 365, the slider 36621 is not moved relative to one of the connecting arms 364. Correspondingly, when the user rotates the grip portion 366112 and drives the slider 36621 to move through the linkage rod 36612, the slider 36621 is driven by the linkage rod 36612 (e.g., subjected to external force), and is moved relative to one of the connecting arms 364.

As shown in FIG. 17, it is worth mentioning that, in the present embodiment, the exercise kit 3 can further include two fixing elements 381 and two moving elements 382. It should be noted that the two fixing elements 381 and the two moving elements 382 respectively adopt the same structure in this embodiment. Therefore, for convenience of explanation, the following description only describes one of the two fixing elements 381 and a corresponding one of the two moving elements 382.

The fixing element 381 is fixed to the base 331 of the supporting structure 33, and the moving element 382 is connected to one of the rotating components 361, such that the moving element 382 and the corresponding rotating component 361 are simultaneously rotatable. The fixing element 381 can include at least one groove 3811 and at least one limiting element 3812, and the moving element 382 can include a main body 3821 and at least one protrusion 3822. Moreover, the main body 3821 of the moving element 382 is, for example, a disk-shaped structure, and the protrusion 3822 is formed by outwardly extending from the main body 3821 of the moving element 382. The moving element 382 is pivotally connected to the fixing element 381, and the protrusion 3822 of the moving element 382 is located in the groove 3811 of the corresponding fixing element 381. When the moving element 382 is rotated with the corresponding rotating component 361, and the protrusion 3822 abuts against the limiting element 3812, the protrusion 3822 and the limiting element 3812 are jointly configured to limit the corresponding rotating components 361, such that the corresponding rotating component 361 cannot rotate anymore, thereby achieving the purpose of limiting the rotation range of a corresponding one of the pedal modules 36.

As shown in FIG. 16 and FIG. 17, more specifically, when the user removes their feet from the pedals 365, the springs 34 drive the rotating components 361 to rotate in a direction toward the seat body 1. When the protrusion 3822 abuts against the limiting element 3812 during the corresponding rotating component 361 being rotated in a direction toward the seat body 1, the rotating component 361 is limited by the limiting element 3812 and the protrusion 3822, such that the rotating component 361 cannot rotate in the direction toward the seat body 1. In other words, in practice, the relevant personnel can provide the different positions of the protrusion 3822 and the limiting element 3812 to avoid the issue of pinching the user's feet when the pedals 365 are rotated in the direction toward the seat body 1 by the springs 34.

As mentioned above, the exercise kit 3 of this embodiment through the design of the adjustment modules 366 allows the user to change the position of one end of each of the two springs 34 by operating the adjustment modules 366 according to requirements, thereby changing the resistance of the springs 34 back to the user's feet.

It should be emphasized that the above-mentioned exercise kit 3 of the present disclosure can be manufactured or sold independently, and the exercise kit 3 is not limited to being manufactured or sold together with the seat body 1 and the chair leg module 2.
