[0021] The following is for reference. Figures 1-15 This describes a seat 100 and a footrest 10 according to an embodiment of the present utility model. Wherein, as... Figure 1 As shown, seat 100 can be a children's dining chair. Of course, this utility model is not limited to this. Seat 100 can also be other child support devices with foot pedal 10.

[0022] like Figure 2 and Figure 3 As shown, for reference Figure 13 According to an embodiment of the present utility model, the foot pedal 10 includes a body part 1, a foot pedal part 2, a reinforcing rib assembly 3, and a mounting arm 4.

[0023] Specifically, one end of the foot pedal 2 is connected to the lower end of the main body 1, and the other end extends toward one side of the thickness direction of the main body 1. The foot pedal 2 and the main body 1 are at an angle to each other, and a foot pedal space 21 is defined between the foot pedal 2 and the main body 1. The mounting arm 4 is located at the upper end of the main body 1. It can be understood that the mounting arm 4 and the foot pedal 2 are respectively located at opposite ends of the main body 1. The mounting arm 4 is used to mount the foot pedal 10.

[0024] The foot pedal 2 and the main body 1 can be substantially perpendicular, and a right-angle foot pedal space 21 can be defined between the main body 1 and the foot pedal 2.

[0025] refer to Figure 1 As shown, the mounting arm 4 can be connected to the front end of the seat plate 20 of the seat 100. At this time, the foot pedal 2 is located at the lower end of the body part 1. The end of the foot pedal 2 away from the body part 1 can extend forward. The foot pedal 2 can support the user's feet, and the body part 1 can support the user's calves, etc., to improve the user's comfort.

[0026] like Figure 2 and Figure 3 As shown, the reinforcing rib assembly 3 is located on the side of the body part 1 and the foot pedal part 2 away from the foot pedal space 21, thereby improving the structural strength of the body part 1 and the foot pedal part 2, improving and increasing the load-bearing strength when carrying the user, reducing the risk of the foot pedal 10 breaking, and ensuring the user's safety and comfort.

[0027] According to the embodiment of the present utility model, the foot pedal 10 can improve the structural strength of the body part 1 and the foot pedal part 2 by providing a reinforcing rib assembly 3 on the side away from the foot pedal space 21. At the same time, it can improve and enhance the load-bearing strength when carrying the user, reduce the risk of the foot pedal 10 breaking, and ensure the safety and comfort of the user.

[0028] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, for reference Figure 13 The edges of the body part 1 and the foot pedal part 2 are provided with flanges 13 extending away from the foot pedal space 21. The flanges 13 can extend along the length direction of the edges of the foot pedal part 2 and the body part 1. On the one hand, the flanges 13 can reduce the sharpness of the edges of the foot pedal part 2 and the body part 1, which helps to protect the user and reduce the possibility of injury during use. On the other hand, the flanges 13 can increase the structural strength of the entire foot pedal 10, thereby increasing the load-bearing capacity of the foot pedal 10 for the user, while reducing the risk of the foot pedal 10 breaking, ensuring the safety and comfort of the user.

[0029] like Figure 2 and Figure 3As shown, the reinforcing rib assembly 3 includes a plurality of first reinforcing ribs 31 and a plurality of second reinforcing ribs 32, wherein the plurality of first reinforcing ribs 31 are arranged along the vertical direction of the body portion 1 (e.g., Figure 2 The first reinforcing rib 31 is spaced apart on the side of the main body 1 away from the footrest space 21 (as shown in the V direction), and is positioned along the transverse direction of the main body 1 (e.g., in the V direction). Figure 2 Extending in the W direction (as shown), the first reinforcing rib 31 extends laterally, with both ends connected to the flange 13. Multiple second reinforcing ribs 32 are spaced apart along the lateral direction of the body part 1 on the sides of the body part 1 and the foot pedal part 2 opposite to the foot pedal space 21. The second reinforcing ribs 32 extend vertically in the body part 1, with both ends connected to the flange 13. It is understood that the multiple first reinforcing ribs 31 and the multiple second reinforcing ribs 32 are intersecting and connected.

[0030] Multiple first reinforcing ribs 31 and multiple second reinforcing ribs 32 can strengthen the structural strength of the body part 1 and the foot pedal part 2. In addition, the multiple first reinforcing ribs 31 and multiple second reinforcing ribs 32 are connected to the flange 13, which can further strengthen the structural strength of the entire foot pedal 10, while improving and increasing the load-bearing strength when carrying the user, reducing the risk of the foot pedal 10 breaking, and ensuring the user's safety and comfort.

[0031] Furthermore, such as Figure 2 and Figure 3 As shown, along the transverse direction of the body part 1, the density of the second reinforcing rib 32 in the middle region between the body part 1 and the foot pedal part 2 is greater than the density of the second reinforcing rib 32 in the edge region. This can effectively strengthen the structural strength of the middle region between the body part 1 and the foot pedal part 2 along the transverse direction of the body part 1, thereby improving the load-bearing strength of the middle region between the body part 1 and the foot pedal part 2 along the transverse direction of the body part 1 for the user and providing better support for the user.

[0032] like Figure 2 and Figure 3 As shown, in the thickness direction of the body part 1, the height of the second reinforcing rib 32 connected to the foot pedal part 2 is greater than the height of the second reinforcing rib 32 connected to the body part 1. This allows for better adaptation to the shape of the foot pedal part 2 and the body part 1, while further enhancing the structural strength of the foot pedal part 2 and its load-bearing capacity to the user, thus preventing breakage between the foot pedal part 2 and the body part 1.

[0033] In some embodiments of this utility model, such as Figure 2 and Figure 3As shown, multiple first reinforcing ribs 31, flanges 13, and second reinforcing ribs 32 adjacent to flanges 13 define multiple sub-spaces 33. The reinforcing rib assembly 3 also includes a third reinforcing rib 34, which is provided in at least a portion of the sub-spaces 33. The two ends of the third reinforcing rib 34 in the longitudinal direction are connected to flanges 13 and second reinforcing ribs 32, respectively. The extension direction of the third reinforcing rib 34 forms an angle with the first reinforcing ribs 31 and second reinforcing ribs 32. Thus, the third reinforcing rib 34 can further strengthen the structural strength of the foot pedal 10 along the lateral edge region of the body 1, thereby improving the overall structural strength of the foot pedal 10, improving the load-bearing capacity when supporting a user, reducing the risk of foot pedal 10 breakage, and ensuring user safety and comfort.

[0034] Furthermore, such as Figure 2 and Figure 3 As shown, at least a portion of the subspace 33 is provided with a plurality of third reinforcing ribs 34, and at least two of the third reinforcing ribs 34 have intersecting extension directions. This allows the two intersecting third reinforcing ribs 34 to bear pressure from different directions, thereby improving the load-bearing strength when supporting the user, reducing the risk of the foot pedal 10 breaking, and ensuring the user's safety and comfort.

[0035] In some embodiments of this utility model, the third reinforcing ribs 34 at both ends of the foot pedal 10 are symmetrically arranged along the transverse direction of the main body 1. This ensures that the structural strength of the foot pedal 10 at both ends along the transverse direction of the main body 1 is approximately the same, guaranteeing the reliability of the foot pedal 10 when bearing the user and avoiding the situation where the foot pedal 10 is tilted due to uneven strength at both ends.

[0036] For example, in Figure 2 In the example shown, the foot pedal 10 has a first end 10a and a second end 10b at its two ends along the lateral direction of the body 1. Both the first end 10a and the second end 10b are provided with a third reinforcing rib 34 in the two sub-spaces 33 near the mounting arm 4. The two sub-spaces 33 with the third reinforcing rib 34 have a larger volume than the sub-spaces 33 far from the mounting arm 4. Therefore, in order to facilitate the layout of the third reinforcing rib 34, one third reinforcing rib 34 is provided in one sub-space 33 near the mounting arm 4, and two third reinforcing ribs 34 are provided in one sub-space 33 far from the mounting arm 4.

[0037] The third reinforcing rib 34 at the first end 10a and the third reinforcing rib 34 at the second end 10b are symmetrically arranged. The following description takes the first end 10a as an example. One of the third reinforcing ribs 34 in a subspace 33 near the mounting arm 4 is inclined in the direction away from the mounting arm 4 in the direction from the first end 10a to the second end 10b. Of the two third reinforcing ribs 34 in a subspace 33 away from the mounting arm 4, one of the three is inclined in the direction away from the mounting arm 4 in the direction from the first end 10a to the second end 10b, and the other is inclined in the direction near the mounting arm 4 in the direction from the first end 10a to the second end 10b.

[0038] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, for reference Figure 13 The foot pedal 2 is provided with a fifth reinforcing rib 22. The fifth reinforcing rib 22 extends in the transverse direction of the body part 1 and is provided in multiple ribs spaced apart in the width direction of the foot pedal 2. The fifth reinforcing rib 22 is formed by a portion of the foot pedal 2 protruding or recessing on one side toward the thickness direction of the foot pedal 2.

[0039] Optionally, the foot pedal 10 is a single piece, which can be injection molded as a single unit.

[0040] Optionally, the foot pedal 10 is made of plastic.

[0041] like Figure 1 As shown, the seat 100 according to an embodiment of the present invention includes a seat plate 20 and the aforementioned footrest 10. A mounting arm 4 is connected to the front end of the seat plate 20. The footrest 2 is located at the lower end of the main body 1, and the end of the footrest 2 facing away from the main body 1 can extend forward. The footrest 2 can support the user's feet, and the main body 1 can support the user's lower legs, thus improving user comfort. Here, "front side" refers to the area in front of the user when sitting on the seat 100.

[0042] In some embodiments of this utility model, such as Figure 1 As shown, the seat 100 may also include a backrest 40, which is connected to the rear end of the seat 20 and extends upward, allowing the user's back to rest against the backrest 40, thus improving user comfort. The seat 100 may also include a support leg 50, the upper end of which may be connected to at least one of the seat 20 and the backrest 40 to support the seat 20 and the backrest 40.

[0043] Furthermore, the front side of the backrest 40 may also be equipped with a seat belt or similar device to secure the child to the seat 100 and prevent the child from falling off the seat 100.

[0044] In some embodiments of this utility model, such as Figure 1As shown, the seat 100 can be a children's high chair. The seat 100 may also include a shelf 60, which is located in front of the backrest 40. The left and right ends of the shelf 60 are connected to at least one of the seat 20, the backrest 40 or the support leg 50. When the user is using the chair, the shelf 60 is located in front of the user. The shelf 60 can be used to place items, such as toys or tableware.

[0045] Furthermore, the shelf 60 has a storage slot on top, which can be used to place items such as water cups, making it easier to secure the items and prevent them from falling.

[0046] Optionally, the seat 20, backrest 40, and shelf 60 are made of plastic.

[0047] Optionally, the seat 20 and the backrest 40 are a single piece, for example, they can be injection molded as a single unit.

[0048] According to the embodiment of the present utility model, the seat 100, by setting the foot pedal 10, and setting the reinforcing rib assembly 3 on the side of the main body 1 and the foot pedal 2 away from the foot pedal space 21, can improve the structural strength of the main body 1 and the foot pedal 2, and at the same time improve and increase the load-bearing strength when carrying the user, reduce the risk of the foot pedal 10 breaking, and ensure the safety and comfort of the user.

[0049] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the mounting arm 4 and the seat plate 20 are rotatably connected, and a connecting adjustment structure 30 is provided between the mounting arm 4 and the seat plate 20. The connecting adjustment structure 30 is used to adjust the angle between the body part 1 and the seat plate 20. Thus, the angle between the body part 1 and the seat plate 20 of the foot pedal 10 can be adjusted according to the user's needs, providing better support for the user's feet and lower legs, improving user comfort, and meeting different user needs.

[0050] Furthermore, such as Figure 4 and Figure 5 As shown, for reference Figures 6-8 The seat plate 20 is provided with a connecting groove 201, and the mounting arm 4 extends into the connecting groove 201. The connecting adjustment structure 30 includes a locking member 301, a positioning member 302, an elastic member (not shown in the figure), and a driving member 303.

[0051] Specifically, the locking member 301 is movably mounted on the mounting arm 4 in the transverse direction of the main body 1. The locking member 301 has multiple fixing grooves 3011 on the side facing away from the mounting arm 4, with different extending directions. The positioning member 302 is located on the side of the locking member 301 facing away from the mounting arm 4 and is connected to the inner wall of the connecting groove 201. The positioning member 302 has a fixing protrusion 3021 on the side facing the locking member 301, which is adapted to engage with one of the fixing grooves 3011. An elastic member is located between the locking member 301 and the mounting arm 4, used to drive the locking member 301 to move towards the positioning member 302. When the fixing protrusion 3021 and one of the fixing grooves 3011 are opposite each other, the elastic member can drive the locking member 301 to move towards the positioning member 302 so that the fixing protrusion 3021 is located within the fixing groove 3011. The driving member 303 is disposed on the seat plate 20 and the positioning member 302 in the transverse direction of the main body 1. The driving member 303 is movable in the transverse direction of the main body 1 and abuts against the locking member 301.

[0052] When the foot pedal 10 is fixed, the fixing protrusion 3021 on the positioning member 302 is located in one of the fixing grooves 3011. Since the positioning member 302 is relatively fixed to the seat plate 20, and the cooperation between the fixing protrusion 3021 and the fixing groove 3011 fixes the locking member 301 relative to the positioning member 302, the mounting arm 4 connected to the locking member 301 is fixed relative to the seat plate 20, and thus the foot pedal 10 is fixed relative to the seat plate 20. When adjusting the angle of the foot pedal 10, it can be achieved by pressing the driving member 303. Specifically, pressing the driving member 303 towards the locking member 301 will push the locking member 301 to overcome the elastic force of the elastic member and move it away from the positioning member 302. The fixing groove 3011 on the locking member 301 and the fixing protrusion 3021 on the positioning member 302 disengage, and the locking member 301 and the mounting arm 4 connected to the locking member 301 can rotate relative to the seat plate 20, thereby allowing the foot pedal 10 to rotate. After the foot pedal 10 rotates to the angle required by the user and the fixing protrusion 3021 is opposite to one of the fixing grooves 3011, the driving member 303 is released. Under the action of the elastic member, the locking member 301 is driven to move toward the positioning member 302, and the fixing protrusion 3021 is re-engaged into the fixing groove 3011, thereby fixing the locking member 301 and the mounting arm 4, thus completing the adjustment of the foot pedal 10 angle and the fixing of the foot pedal 10.

[0053] In some embodiments of this utility model, such as Figures 9-12 As shown, for reference Figure 14The mounting arm 4 has a mounting groove 41 on the side facing the positioning member 302. The locking member 301 is at least partially located in the mounting groove 41. The side wall of the mounting groove 41 has a notch 42. The fixing protrusion 3021 passes through the notch 42. The two side walls of the notch 42 along the circumferential direction of the mounting groove 41 are used to abut against the fixing protrusion 3021 to limit the rotation angle of the foot pedal 10. It can be understood that the fixing protrusion 3021 can rotate relative to the foot pedal 10 within the angle range defined by the notch 42.

[0054] like Figure 9 and Figure 10 As shown, when the foot pedal 10 is adjusted in angle and the foot pedal portion 2 of the foot pedal 10 is raised, the foot pedal 10 reaches its upper limit position when the fixed protrusion 3021 abuts against one of the inner walls of the notch 42; Figure 11 and Figure 12 As shown, when the foot pedal 10 is adjusted at an angle and the foot pedal 2 of the foot pedal 10 is lowered, the foot pedal 10 reaches the lower limit position of descent when the fixed protrusion 3021 abuts against the other inner wall of the notch 42.

[0055] In this application, the angle adjustment range of the foot pedal 10 is better limited by the cooperation between the fixed protrusion 3021 and the inner wall of the notch 42, so as to avoid the foot pedal 10 rotating too much and disengaging from the seat plate 20.

[0056] In some embodiments of this utility model, such as Figure 6 As shown, the locking member 301 has an annular protrusion on the side facing the positioning member 302. Each fixing groove 3011 includes two grooves that penetrate the annular protrusion along the radial direction of the locking member 301. The two grooves are arranged opposite each other along the radial direction of the locking member 301. Correspondingly, as shown... Figure 7 As shown, the fixed protrusion 3021 includes two sub-protrusions spaced apart, and the two sub-protrusions respectively cooperate with the two grooves.

[0057] In some embodiments of this utility model, such as Figure 5 and Figure 8 As shown, the driving component 303 includes a driving body 3031 and a claw 3032. The driving body 3031 is located on the side of the base plate 20 opposite to the positioning component 302. The claw 3032 passes through the base plate 20 and the positioning component 302 and abuts against the locking component 301. The end of the claw 3032 opposite to the driving body 3031 has a hook 3033, which is adapted to abut against the surface of the positioning component 302 facing the locking component 301. When the fixing protrusion 3021 and the fixing groove 3011 are engaged, the locking component 301 pushes the driving component 303 to move away from the locking component 301. At this time, the hook 3033 abuts against the surface of the positioning component 302 facing the locking component 301, which can prevent the driving component 303 from disengaging from the base plate 20 and ensure the reliability of the driving component 303's fixation.

[0058] Optionally, such as Figure 8 As shown, there are multiple claws 3032, which are spaced apart along the circumferential direction of the drive body 3031. Multiple hooks 3033 correspond to the multiple claws 3032. For example, in... Figure 8 In the example shown, there are four claws 3032. The four claws 3032 are spaced apart along the circumferential direction of the drive body 3031. Each claw 3032 has a hook 3033 at the end opposite to the drive body 3031.

[0059] In some embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the positioning member 302 has a positioning groove 3022 on the side opposite to the locking member 301, corresponding to the fixing protrusion 3021. The side wall of the connecting groove 201 has a positioning protrusion 202 that mates with the positioning groove 3022. This allows the positioning member 302 to be positioned on the side wall of the connecting groove 201, preventing the positioning member 302 from rotating. At the same time, the claw 3032 of the driving member 303 further fixes the positioning member 302 to the bottom wall of the connecting groove 201.

[0060] exist Figure 5 and Figure 7 In the example shown, the fixed protrusion 3021 includes two sub-protrusions, the positioning groove 3022 includes two sub-positioning grooves, the two sub-positioning grooves are respectively disposed opposite to the two sub-protrusions, and the positioning protrusion 202 includes two sub-positioning protrusions 202, the two sub-positioning protrusions 202 respectively cooperate with the two sub-positioning grooves.

[0061] Optionally, the positioning element 302 can be a metal part, which can increase the structural strength of the positioning element 302, while increasing the connection strength between the foot pedal 10 and the seat plate 20 and increasing the reliability of fixing the foot pedal 10.

[0062] In some embodiments of this utility model, such as Figures 13-15 As shown, the mounting arm 4 has a mounting groove 41 on the side facing the positioning member 302. The bottom wall of the mounting groove 41 has a mounting post 43 and a fixing rib 44. One end of the fixing rib 44 is connected to the inner wall of the mounting groove 41, and the other end is connected to the outer peripheral wall of the mounting post 43. Multiple fixing ribs 44 are spaced apart along the circumferential direction of the mounting post 43. At least a portion of the locking member 301 is located within the mounting groove 41. The side of the locking member 301 facing the bottom wall of the mounting groove 41 has a limiting groove 3012 that cooperates with the multiple fixing ribs 44. The cooperation of the multiple limiting grooves 3012 and the multiple fixing ribs 44 restricts the rotation of the locking member 301 within the mounting groove 41, thereby achieving relative fixation between the locking member 301 and the mounting arm 4.

[0063] In addition, the locking member 301 has a clearance groove 3013 on the side facing the bottom wall of the mounting groove 41 to avoid the mounting post 43, and multiple limiting grooves 3012 are connected to the clearance groove 3013.

[0064] In some embodiments of this utility model, such as Figures 13-15 As shown, the mounting post 43 is provided with a first mounting hole 431, which penetrates the bottom wall of the mounting post 43 and the mounting groove 41. The locking member 301 is provided with a second mounting hole 3014, which is opposite to the first mounting hole 431. Figure 5 and Figure 7 As shown, the positioning component 302 is provided with a third mounting hole 3023, and the seat plate 20 is provided with a fourth mounting hole 203. The rotating shaft can pass through the first mounting hole 431, the second mounting hole 3014, the third mounting hole 3023 and the fourth mounting hole 203 to facilitate the rotational connection between the foot pedal 10 and the seat plate 20.

[0065] In some embodiments of this utility model, two mounting arms 4 are spaced apart along the lateral direction of the body portion 1, i.e., the left-right direction of the seat 100. Correspondingly, there are two connecting grooves 201, and the two mounting arms 4 extend into the two connecting grooves 201 respectively. Further, the two mounting arms 4 are located at both ends of the body portion 1 along the lateral direction of the body portion 1.

[0066] Other configurations and operations of the seat 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
