[0041] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0042] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.

[0043] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0044] like Figure 1-4 As shown, an adjustable table and chair 10 is provided in one embodiment of the present invention, including a support 1, a seat 2 and a table board 3, wherein the seat 2 is detachably connected to the support 1.

[0045] The tabletop component 3 includes a first tabletop 31 and a second tabletop 32, with the first tabletop 31 and the second tabletop 32 being movably connected.

[0046] The tabletop component 3 has a first state and a second state.

[0047] When the table panel 3 is in the first state, the second table panel 32 moves in the first direction relative to the first table panel 31, the second table panel 32 is stacked on top of the first table panel 31, and the first table panel 31 is connected to the seat 2.

[0048] When the tabletop component 3 is in the second state, the second tabletop 32 moves in the second direction relative to the first tabletop 31, and the first tabletop 31 and the second tabletop 32 form a whole board surface. The first tabletop 31 and the second tabletop 32 are connected to the support 1.

[0049] The adjustable table and chair 10 can be adjusted to different usage states to meet different usage needs. It includes a support frame 1, a seat 2, and a tabletop 3, all of which are detachably connected to each other.

[0050] Alternatively, the shape and structure of the bracket 1 and the seat 2 can refer to the shape design of existing children's dining chairs.

[0051] The tabletop component 3 has a first tabletop 31 and a second tabletop 32, which are movably connected and can move relative to each other. Taking the first tabletop 31 as a reference, the direction in which the second tabletop 32 moves closer to the first tabletop 31 is a first direction, and the direction in which the second tabletop 32 moves away from the first tabletop 31 is a second direction. When the second tabletop 32 moves in the first direction, the first tabletop 31 and the second tabletop 32 partially overlap, reducing the overall area of ​​the tabletop component 3, which is in the first state. When the second tabletop 32 moves in the second direction, the overlap between the first tabletop 31 and the second tabletop 32 decreases, increasing the overall area of ​​the tabletop, which is in the second state.

[0052] When the tabletop component 3 is in the first state, it is used in conjunction with the seat 2, with the seat 2 mounted on the bracket 1 and the tabletop component 3 mounted on the seat 2. At this time, the adjustable table and chair 10 can be used as a children's dining chair, and the tabletop component 3 is used to place bowls, chopsticks, and other items.

[0053] When the tabletop component 3 is in the second state, it is used in conjunction with the support 1, wherein the chair 2 is removed from the support 1 and the tabletop component 3 is installed on the support 1. At this time, the adjustable table and chair 10 can be used as a small table.

[0054] Optionally, the first tabletop 31 and the second tabletop 32 can move by sliding, with a cavity provided at the end of the first tabletop 31, and the second tabletop 32 slidably connected to the cavity. When the tabletop 3 is in the first state, the second tabletop 32 slides into the first tabletop 31. When the tabletop 3 is in the second state, the second tabletop 32 slides to the outside of the first tabletop 31. Alternatively, the first tabletop 31 and the second tabletop 32 can move by rotation, with the first tabletop 31 and the second tabletop 32 hinged. When the tabletop 3 is in the first state, the second tabletop 32 rotates in the opposite direction and stacks on top of the first tabletop 31. When the tabletop 3 is in the second state, the second tabletop 32 rotates in the forward direction, and the first tabletop 31 and the second tabletop 32 unfold.

[0055] In one embodiment, such as Figure 3-9As shown, the tabletop component 3 is equipped with a first locking device 4 and a second locking device 5. When the tabletop component 3 is in the first state, the first locking device 4 locks the first tabletop 31 and the second tabletop 32. When the tabletop component 3 is in the second state, the second locking device 5 locks the first tabletop 31 and the second tabletop 32.

[0056] Specifically, the adjustable table and chair 10 also has a first locking device 4 and a second locking device 5, both of which are used to lock and fix the first tabletop 31 and the second tabletop 32. The first locking device 4 locks the tabletop 3 when it is in the first state, at which point the first tabletop 31 and the second tabletop 32 are securely held, maintaining the tabletop 3 in the first state. The second locking device 5 locks the tabletop 3 when it is in the second state, at which point the first tabletop 31 and the second tabletop 32 are securely held, maintaining the tabletop 3 in the first state.

[0057] Optionally, the first locking device 4 includes a first hook and a first locking block. The first hook is connected to the end of the first tabletop 31, and the first locking block is connected to the end of the second tabletop 32. When the tabletop 3 is in the first state, the ends of the first tabletop 31 and the second tabletop 32 are aligned, and the first hook engages with the first locking block, making the first tabletop 31 and the second tabletop 32 securely connected. The second locking device 5 includes a second hook and a second locking block. The second hook is connected to the side of the first tabletop 31, and the second locking block is connected to the side of the second tabletop 32. When the tabletop 3 is in the second state, the side of the first tabletop 31 and the side of the second tabletop 32 are on the same plane, and the second hook engages with the second locking block, making the first tabletop 31 and the second tabletop 32 securely connected. The first locking device 4 and the second locking device 5 can also be other structures, as long as they can securely connect the first tabletop 31 and the second tabletop 32.

[0058] In one embodiment, such as Figure 3 and Figure 5-7 As shown, the first locking device 4 includes a locking button 41, an unlocking button 42, and a locking member. When the tabletop 3 is in the first state, the locking button 41 is triggered, connecting the locking button 41 to the locking member, thus locking the first tabletop 31 and the second tabletop 32 in place. When the unlocking button 42 is triggered, the locking button 41 separates from the locking member, allowing the first tabletop 31 and the second tabletop 32 to move, enabling the tabletop 3 to be in the second state.

[0059] Specifically, the first locking device 4 consists of a locking button 41, an unlocking button 42, and a locking element. The locking button 41 and unlocking button 42 are mounted on the first tabletop 31, and the locking element is mounted on the second tabletop 32. The locking button 41 has a locking portion, and the unlocking button 42 has an unlocking portion. When the tabletop 3 is in the first state, pressing the locking button 41 causes its locking portion to extend into the second tabletop 32 and connect with the locking element, thus securing the first tabletop 31 and the second tabletop 32. When unlocking is required, pressing the unlocking button 42 causes its unlocking portion to trigger the locking portion to separate from the locking element, allowing the first tabletop 31 and the second tabletop 32 to move again.

[0060] In one embodiment, such as Figure 3 and Figure 5-7 As shown, the locking button 41 and the unlocking button 42 are slidably connected to the first tabletop 31. The locking element includes a locking plate 43, which is slidably connected to the second tabletop 32. When the locking button 41 is pressed, the locking button 41 engages with the locking plate 43, and the elastic member 44 deforms. When the unlocking button 42 is pressed, the unlocking button 42 pushes the locking plate 43 away from the locking button 41.

[0061] Specifically, the first tabletop 31 has a first button hole and a second button hole spaced apart. A locking button 41 is slidably connected to the first button hole, and an unlocking button 42 is slidably connected to the second button hole. The locking part is connected to a locking block on the locking button 41, and the locking block has a locking groove 411. The unlocking part is connected to a push block 421 on the unlocking button 42.

The locking plate 43 is slidably connected to the receiving cavity, and the elastic element 44 is located inside the receiving cavity and outside the locking plate 43. The second tabletop 32 is also provided with a first opening and a second opening communicating with the receiving cavity. The locking plate 43 is provided with a snap-fit ​​portion 431 that can cooperate with the locking groove 411 and an abutment portion 432 that cooperates with the push block 421.

[0063] When the tabletop component 3 is in the first state, the first button hole is aligned with the first opening, and the second button hole is aligned with the second opening. When locking is required, pressing the locking button 41 causes it to slide toward the locking plate 43. The locking block extends into the receiving cavity through the first opening, abuts against the latching part 431, and pushes the locking plate 43 to slide. The elastic element 44 is deformed by the locking plate 43. When the locking groove 411 is aligned with the latching part 431, the locking groove 411 provides displacement space. At this time, the elastic element 44 recovers part of its deformation, pushes the locking plate 43 to move, and places the latching part 431 in the locking groove 411, thus achieving locking. When unlocking is required, pressing the unlock button 42 causes it to slide toward the locking plate 43. The locking block extends into the receiving cavity through the second opening and abuts against the abutting part 432. After contact, the unlock button 42 pushes the locking block to slide, the locking block squeezes the elastic member 44, and causes the snap-fit ​​part 431 to leave the locking groove 411.

[0064] Optionally, a first spring is provided in the first button hole, and a second spring is provided in the second button hole. The first spring is used to lock the button 41 and reset it, and the second spring is used to unlock the button 42 and reset it.

[0066] In one embodiment, such as Figure 4 and Figure 8-9 As shown, the second locking device 5 includes a locking rod 51 and an operating button 52 connected to the locking rod 51. The locking rod 51 is slidably connected to the first tabletop 31, and the second tabletop 32 is provided with an insertion hole 321. When the tabletop 3 is in the first state, the locking rod 51 is located inside the first tabletop 31. When the tabletop 3 is in the second state, a portion of the locking rod 51 is located inside the insertion hole 321.

[0067] Specifically, the second locking device 5 includes an operating button 52 and a locking rod 51, with the locking rod 51 connected to the operating button 52. A slide rail is provided on the first tabletop 31, and the locking rod 51 is slidably connected within the slide rail. The operating button 52 is located on the outside of the first tabletop 31. A mating hole is provided on the second tabletop 32. When the tabletop 3 is in the second state, the slide rail is aligned with the mating hole. When locking is required, the operating button 52 is operated to slide the locking rod 51 toward the mating hole, inserting the locking rod 51 into the mating hole.

[0068] In one embodiment, such as Figure 1 , Figure 3 and Figure 5As shown, the tabletop component 3 also includes a fastener 6, which includes a first fastening plate 61 and a second fastening plate 62. The first fastening plate 61 is fixedly connected to the first tabletop 31, and the second fastening plate 62 is movably connected to the first tabletop 31.
