The multifunctional chair 100 of the present disclosure includes a supporting body 1, a telescopic structure 2, a seat body 3, two pedal assemblies 4, two auxiliary wheels 5, and two armrest structures 6. In other embodiments, the multifunctional chair 100 can include only one pedal assembly 4. In another embodiment, the multifunctional chair 100 can be provided to not include the auxiliary wheels 5.

(14) The supporting body 1 includes a placement portion 11, two inclined rods 12, and a fixing portion 13. The placement portion 11 is configured to be placed on the ground. The placement portion 11 can be, for example, made of a plurality of rods, but the structure of the placement portion 11 and the components included by the placement portion 11 are not limited to those shown in the figures. Two ends of each of the inclined rods 12 are respectively connected to the placement portion 11 and the fixing portion 13. The quantity of the inclined rods 12 included by the supporting body 1 and the structure and the dimension of each of the inclined rods 12 are not limited to those shown in the figures. The placement portion 13 is configured to be fixed to the seat body 3. The fixing portion 13 is primarily configured to allow the seat body 3 to be stably connected to the supporting body 1, and accordingly, the structure and the dimension and the components included by the fixing portion 13 can be designed according to the structure and the dimension of the seat body 3.

(15) The telescopic structure 2 is movably connected to the placement portion 11, and the telescopic structure 2 can be operated to move relative to the placement portion 11 in a direction away from the supporting body 11 or in a direction toward the supporting body 11. More specifically, the telescopic structure 2 can be operated to move in the direction away from the supporting body 11, so as to protrude from a front edge 3A of the seat body 3 (as shown in FIG. 5 and FIG. 6). Or, the telescopic structure 2 can be operated to move in the direction toward the supporting body 11, so as to not protrude from the front edge 3A of the seat body 3 (as shown in FIG. 1 and FIG. 3).

(16) In a practical application, the placement portion 11 can include two hollow tubes, the telescopic structure 2 can include two tubes, the two tubes of the telescopic structure 2 can be respectively disposed in the two hollow tubes of the placement portion 11, and when the telescopic structure 2 is operated, the two tubes of the telescopic structure 2 can move relative to the two hollow tubes. The practical manner in which the telescopic structure 2 and the placement portion 11 are connected to and fixed to each other is not limited to that shown in the figures. In an embodiment, the telescopic structure 2 can be fixed to the placement portion 11 through a plurality of screws, or the telescopic structure 2 can have two operation assemblies. When each of the operation assemblies is not operated, the telescopic structure 2 and the placement portion 11 are fixed to each other, and when the two operation assemblies are operated, the telescopic structure 2 moves telescopically relative to the placement portion 11.

(17) The seat body 3 can include a seat board structure 31 and a backrest structure 32. A rear edge of the seat board structure 31 is connected to the backrest structure 32. The seat board structure 31 is configured to be sat upon by a user, and the backrest structure 32 is configured to be abutted against by the user's back. The seat board structure 31 is fixed to the fixing portion 13 of the supporting structure 1. The structure and the dimensions of the seat board structure 31 and the backrest structure 31 are not limited to those shown in the figures.

(18) Referring to FIG. 1, and FIG. 3 to FIG. 6. FIG. 4 and FIG. 5 are schematic views of a telescopic structure and a movable rod of the multifunctional chair that have been operated according to the present disclosure, and FIG. 6 is a schematic view showing a user utilizing the multifunctional chair to do exercise according to the present disclosure. The two pedal assemblies 4 are connected to the supporting body 1. Each of the pedal assemblies 4 includes a fixing rod 41, a movable rod 42, an operation portion 43, and an elastic resistance member 44. In each of the pedal assemblies 4, one end of the fixing rod 41 is pivotally connected to the supporting body 1. The movable rod 42 is connected to the fixing rod 41 and is able to telescopically move relative to the fixing rod 41. The operation portion 43 is disposed at one end of the movable rod 42 away from the fixing rod 41. The operation portion 43 and the movable rod 42 connected thereto are substantially in a shape of the letter “T”, but the present disclosure is not limited thereto. The operation portion 43 is primarily configured to be abutted by a sole or a palm of the user, and two ends of the elastic resistance member 44 are respectively fixed to the supporting body 1 and the fixing rod 41. The elastic resistance member 44 can be, for example, a stretching spring, but the present disclosure is not limited thereto. Any component that can elastically deform to provide elastic resistance should fall within the applicable scope of the elastic resistance member 44.

(19) Each of the movable rods 42 can be operated to move relative to the fixing rod 41 connected thereto, so that each of the operation portions 43 can be stored away (e.g., tucked or hidden) below the seat body 3 or can protrude from the front edge 3A of the seat body 3. When the user operates the telescopic structure 2 and the two movable rods 42 to allow the telescopic structure 2 and the two operation portions 43 to protrude from the front edge 3A of the seat body 3, the user can utilize the multifunctional chair 100 to do muscle training exercises.

(20) More specifically, as shown in FIG. 6, the user seating on the chair body 3 can apply force to the two operation portions 43 by the user's feet, so that the two operation portions 43 rotate relative to the supporting body 1 together with the movable rods 42 and fixing rods 41 connected to the operation portions 43, and the two elastic resistance members 44 are driven to be in a stretched state to provide the elastic resistance. In other words, when the user's feet are placed on the two operation portions 43, the user has to apply enough force to resist the elastic resistance provided by the two elastic resistance members 44, so that a muscle training effect can be achieved.

(21) According to the above, when the user wishes to utilize the multifunctional chair 100 for muscle training, only a simple operation is needed to allow the two operation portions 43 and the telescopic structure 2 to protrude from the front edge 3A of the seat board structure 31, and enable the user to start exercising. After the user finishes exercising, only a simple operation is needed for the two operation portions 43 and the telescopic structure 2 to be re-positioned inwards and no longer protrude from the front edge 3A of the seat board structure 31, such that the multifunctional chair 100 can accordingly be used as a normal office chair.

(22) It is worth mentioning that, by the design of the telescopic structure 2, the supporting body 1 is in contact with the ground P by a greater area, so as to prevent the multifunctional chair 100 from capsizing during exercise. In other words, without the telescopic structure 2 of the present disclosure, it is possible for the multifunctional chair 100 to capsize when being utilized for exercise, unless the multifunctional chair 100 itself possesses an extremely heavy weight.

(23) In a preferable embodiment, after the telescopic structure 2 is operated, a length L1 of the telescopic structure 2 protruding from the front edge 3A of the seat body 3 is greater than or equal to one third of a length L2 of the seat board structure 31. Therefore, the multifunctional chair 100 can be effectively prevented from capsizing when the user is using the multifunctional chair 100, especially when an overall weight of the multifunctional chair 100 of an embodiment is relatively light.

(24) As shown in FIG. 7, FIG. 7 is a partial sectional schematic view of the movable rod and a fixing rod of the multifunctional chair of the present disclosure. In each of the pedal assemblies 4 of a practical embodiment, the movable rod 42 can have two retaining holes 421, the fixing rod 41 can have a retaining hole 411, and the user can use a pin S to penetrate through one of the retaining holes 421 of the movable rod 42 and the retaining hole 411 of the fixing rod 41, so that the movable rod 42 cannot move relative to the fixing rod 41. It should be noted that, the manner in which the movable rod 42 and the fixing rod 41 are fixed to each other is not limited to the above description and can be changed according to practical requirements. Naturally, in other embodiments, the pin S can be replaced by a component such as a screw.

(25) As shown in FIG. 3, FIG. 5, and FIG. 7, in each of the pedal assemblies 4, when the pin S penetrates through one of the retaining holes 421 of the movable rod 42 and the retaining hole 411 of the fixing rod 41, the corresponding one of the operation portions 43 protrudes from the front edge 3A (as shown in FIG. 5) of the seat board structure 31. Conversely, when the pin S penetrates through another one of the retaining holes 421 and the retaining hole 411 of the fixing rod 41, the corresponding one of the operation portions 43 does not protrude from the front edge 3A (as shown in FIG. 5) of the seat board structure 31. In other words, the retaining holes 421 of the movable rods 42, the retaining hole 411 of the fixing rod 41, and the pin S are primarily in cooperation with each other, so that the corresponding one of the operation portions 43 protrudes from the front edge 3A of the seat board structure 31 or not. Naturally, whether or not the operation portion 43 protrudes from the front edge 3A of the seat board structure 31 is not limited by the design of the present disclosure.

(26) Referring to FIG. 2, FIG. 3, and FIG. 8, FIG. 8 is a schematic side view showing the multifunctional chair sliding through an auxiliary wheel according to the present disclosure. A rear end of the placement portion 11 of the supporting body 1 can be pivotally connected to two auxiliary wheels 5, and each of the auxiliary wheels 5 is configured to rotate relative to the supporting body 1. As shown in FIG. 3, when the placement portion 1 is placed on the ground P, each of the auxiliary wheels 5 is not in contact with the ground P. As shown in FIG. 8, when the user tilts the multifunctional chair 100, the two auxiliary wheels 5 are in contact with the ground P, and the user can easily slide the multifunctional chair 100 by the two auxiliary wheels 5.

(27) In other words, generally, when the user sits on the multifunctional chair 100, since each of the auxiliary wheels 5 is not in contact with the ground P, the multifunctional chair 100 can be stably placed on the ground P. When the user utilizes the multifunctional chair 100 to do exercise, since each of the auxiliary wheels 5 is not in contact with the ground P, the multifunctional chair 100 does not move.

(28) According to the above, referring to FIG. 2 and FIG. 3, in an embodiment, the multifunctional chair 100 can further include a plurality of auxiliary fixing components 7. The auxiliary fixing components 7 are fixed to the placement portion 11, and the placement portion 11 is placed on the ground P through the auxiliary fixing components 7. When the supporting body 1 is placed on the ground P through the auxiliary fixing components 7, a gap G1 is between the supporting body 1 and the ground P, and a gap G2 is between each of the auxiliary wheels 5 and the ground P. Each of the auxiliary fixing components 7 can be, for example, made of a rubber material, and each of the auxiliary fixing components 7 can allow the supporting body 1 to be more stably placed on the ground P.

(29) Referring to FIG. 2, FIG. 9, and FIG. 10, FIG. 9 is a schematic view showing two armrest structures of the multifunction chair that have been operated according to the present disclosure, and FIG. 10 is another schematic view showing the user utilizing the multifunctional chair to do exercise according to the present disclosure. As shown in FIG. 2 and FIG. 9, the two armrest structures 6 are respectively and movably connected to the supporting body 1, and each of the armrest structures 6 can be operated to rotate in a direction toward the backrest structure 32 or in a direction away from the backrest structure 32. In a practical application, each of the armrest structures 6 can be operated to rotate clockwise or counterclockwise for 90 degrees.

(30) As shown in FIG. 9 and FIG. 10, after the user rotates the two armrest structures 6 for 90 degrees relative to the supporting body 1 and allows the operation portions 43 to protrude from the front edge 3A of the seat board structure 31, the user can laterally sit on the seat board structure 31, and the user can operate one of the operation portions 43 with the right hand to do exercise, so that the user can perform body stretching. Conversely, if the user wants to operate the operation portion 43 with the left hand, the user only has to reversely sit on the seat body 3, and the user can operate one of the operation portions 43 with left hand.

(31) Referring to FIG. 11, FIG. 11 is a schematic side view of the multifunction chair according to another embodiment of the present disclosure. In a practical application, in each of the pedal assemblies 4, the fixing rod 41 can include two fixing structures 412, and one end of one of the elastic resistance members 44 is detachably fixed to one of the fixing structures 412. When the user allows the one end of the one of the elastic resistance members 44 to be fixed to different fixing structures 412, the user has to apply different force to rotate the operation portions 43 toward the ground P. Accordingly, different elastic resistance training requirements can be met.

(32) Referring to FIG. 12, FIG. 12 is a partial enlarged schematic view showing that the fixing rod and an elastic resistance member of the multifunctional chair are connected to each other according to an embodiment of the present disclosure. In a practical application, a side wall of the fixing rod 41 of each of the pedal assemblies 4 is recessed to form a sliding slot 413, the fixing rod 41 has a plurality of retaining holes 414 on the side wall having the sliding slot 413 formed thereon, and the sliding slot 413 has a slider 45 disposed therein. The one end of the elastic resistance member 44 is fixed to the slider 45, and the slider 45 can slide in the sliding slot 413. The slider 45 has a thru-hole 451, and the thru-hole 451 penetrates through the slider 45.

(33) The user can utilize a pin S to penetrate through one of the retaining holes 414 and the thru-hole 451 of the slider 45, so that the slider 45 cannot move relative to the fixing rod 41, thereby changing a position where one of the elastic resistance members 44 and the fixing rod 41 are fixed with each other. In other words, by the design of the slider 45, the sliding slot 413, and the pin S, the user can change the position where one of the elastic resistance members 44 and the fixing rod 41 are fixed with each other through a simple operation according to requirements for a degree of elastic resistance. Naturally, the pin S can also be replaced by a component such as a screw in other embodiments.

Beneficial Effects of the Embodiment
