Description

Technical Field

[0001] This invention relates to a multifunctional children's dining chair. Background Technology

[0002] Currently, children's high chairs are becoming increasingly popular with consumers. There are two common types: non-electric and non-electric. Non-electric high chairs have a pivot joint between the seat and backrest. To pass EU safety tests and to minimize the length and aesthetics of the support frame, the angle between the line connecting the front of the seat to the pivot point and the line connecting the backrest to the pivot point is relatively small, around 140°. These are suitable for children aged 6 to 36 months. Some high chairs, however, aim to pass EU safety tests, minimize the length of the support frame, and create a larger angle between the middle of the backrest and the seat. This results in an arched seat, potentially affecting spinal health and causing discomfort. Non-electric high chairs are often limited in function, have low cost-effectiveness, and some may even negatively impact physical and mental development, thus failing to meet the needs of a wider range of consumers.

[0003] Another type of swing available on the market that can also function as a dining chair is patent application number 2014107153671. This patent has a swing position and a non-swing position. As can be seen from the patent drawings and description, when moving from the swing position to the non-swing position, the swing must be locked to the support frame and cannot be unlocked manually. When moving from the non-swing position to the swing position, the back of the swing must return to the angle of the swing position before the seat can be unlocked from the support frame. This means that the angle between the seat and the back of the swing position is smaller than the angle between the seat and the back of the non-swing position. In other words, when the swing swing function is present, the angle between the seat and the back is smaller than the angle between the seat and the back when the seat is fixed to the support frame.

[0004] Currently, there is another type of swing on the market that can be equipped with a dining chair function, as described in patent application number 2015202565139. All claims have a seat with both a dining chair and a swing position. The description states that: because the back cannot be adjusted to be as flat as when the seat is in the swing position as when the seat is in the dining chair position, the angle between the seat and the back is smaller when the seat is in the swing position.

[0005] Although the aforementioned patents all feature swing positions, non-swing positions, or high chair positions, and are suitable for ages from 0 to 6 months and 6 to 36 months, the angle between the seat and back in the swing position for infants aged 0 to 6 months is smaller than that in the non-swing or high chair positions. Therefore, infants aged 0 to 6 months will feel uncomfortable and easily become fussy when sitting in the swing position at the smaller angle between the seat and back, which is detrimental to their healthy development. This is because infants aged 0 to 6 months have very weak lumbar support. Obviously, if the angle between the seat and back is small, the child's body is basically in a sitting position, and the pressure on the lower back from the upper body is very high, so the child will be uncomfortable and fussy, which is detrimental to the child's healthy development. If the angle between the seat and back is larger, the child is basically in a reclining position, and the pressure on the lower back from the upper body is very low, so the child will be comfortable, fussy, and it is also beneficial to the child's healthy development.

[0006] In conclusion, the multi-functional swings or high chairs mentioned above cannot meet the needs of more consumers. The market needs a multi-functional children's high chair that has both a high chair position and a near-reclining position, and the angle between the seat and back when in the near-reclining position is greater than the angle between the seat and back when in the high chair position, in order to meet the needs of more consumers. Summary of the Invention

[0007] This invention realizes a multifunctional children's dining chair that combines the functions of a high chair with a near-flat reclining function, offering high cost-effectiveness and enhanced entertainment. The seat has an adjustable dining position and a reclining position. In the reclining position, the maximum adjustable angle M between the seat and backrest is greater than the maximum adjustable angle N between the seat and backrest in the dining position. The switching between the two adjustable positions can be controlled through the coordinated operation of the seat, the tray, and the linkage mechanism. This multifunctional children's dining chair is suitable for children aged 0 to 36 months and meets the rollover test standards for different application scenarios.

[0008] This invention is achieved through the following technical solution:

[0009] A multifunctional children's high chair includes a support seat, a seat body, a tray, and a linkage mechanism. The seat body includes a seat portion and a backrest, which are pivotally connected. The support seat is connected to and supports the seat body. The tray is detachably connected to the seat portion.

[0010] The seat has an adjustable dining position and an adjustable reclining position. When the reclining position is adjustable, the maximum adjustable angle M between the seat and the back is greater than the maximum adjustable angle N between the seat and the back when the dining position is adjustable.

[0011] When the tray is connected to and locked with the seat, the linkage mechanism can restrict the seat to the adjustable dining position; when the tray is unlocked and separated from the seat, the seat is in the adjustable reclining position, and the linkage mechanism can also prevent the tray from being connected to and locked with the seat, at least when the angle between the seat and the back is greater than the maximum adjustable angle N.

[0012] Furthermore, it also includes an electric motor, which is mounted on the support base and is used to drive the base to swing.

[0013] Furthermore, it also includes a driving member, the first end of which is connected to the support base, and the second end of which is locked or separated from the base. When the driving member is locked to the base, the driving member restricts the swing of the base relative to the support base.

[0014] Furthermore, when the drive unit is locked to the seat, the drive unit can also drive the linkage mechanism to restrict the seat to the adjustable dining position and release the obstruction of the plate.

[0015] Furthermore, the linkage mechanism includes a connector, a first linkage part, and a second linkage part. The first linkage part is used to engage with the plate, and the second linkage part is used to engage with the back. The first end of the connector is connected to the first linkage part, and the second end of the connector is connected to the second linkage part.

[0016] Furthermore, the seat is provided with a slot for inserting a plate, and the first linkage part includes a locking part, which is movably connected to the seat. The insert in the locking part can extend into or retract from the slot, and the locking part is also connected to the connector.

[0017] Furthermore, the locking part includes a locking member that pivots with the seat and is connected to the connector. An insert is disposed on the locking member, and the locking member is rotatable relative to the seat so that the insert can be inserted into or removed from the slot.

[0018] Furthermore, the linkage mechanism also includes a reset part. When the reset part drives the locking part to reset, the insert block extends into the slot so that the seat is in a reclining adjustable state.

[0019] Furthermore, the second linkage includes a transmission member and a blocking member. The blocking member is connected to the back and / or the seat. The transmission member is movably connected to the seat. The transmission member is also connected to the second end of the connector. The transmission member can approach or separate from the blocking member to restrict or allow the continued rotation of the back through the blocking member. When the transmission member approaches to restrict the blocking member, it can prevent the included angle between the seat and the back from being greater than the maximum adjustable included angle N.

[0020] Furthermore, the blocking part is fixedly connected to the back and rotates with the back, and the transmission component can come into contact with or separate from the blocking part to limit or allow the blocking part to continue rotating.

[0021] Furthermore, the linkage mechanism includes a movable part, a reset part, and a blocking part. The movable part is movably arranged relative to the seat. The movable part is used to work in conjunction with the tray and the blocking part. The blocking part is connected to the backrest and / or the seat. The movable part can be close to or separate from the blocking part, thereby limiting or allowing the backrest to continue rotating through the blocking part. When the reset part drives the movable part to reset, the movable part prevents the tray from being locked to the seat and allows the backrest to continue rotating, so that the seat is in a reclining adjustable state.

[0022] Furthermore, the movable part includes a movable member that slides on the seat, and a blocking part that is fixedly connected to the back and rotates with the back. The movable member can come into contact with or separate from the blocking part to restrict or allow the blocking part to continue rotating.

[0023] Furthermore, the seat is provided with a slot for inserting a plate, and one end of the movable part is provided with a stop that extends into or out of the slot. When the plate is inserted into the slot, the plate can push the stop out of the slot. The stop drives the movable part to move, so that the other end of the movable part is close to restrict the continued rotation of the blocking part, so that the seat is in an adjustable position.

[0024] Furthermore, when the reset unit drives the moving member to reset and the included angle between the seat and the back is greater than the maximum adjustable included angle N, the blocking part can be used to abut the moving member to prevent the stop block from exiting the slot.

[0025] Furthermore, a multi-angle adjustment device is provided between the seat and the backrest, which can adjust the angle between the two to keep them at multiple angle positions. Attached Figure Description

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] In the description of this invention, unless otherwise expressly specified and limited, the terms “first,” “second,” “one end,” and “the other end” are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term “a plurality” refers to two or more; and the term “and / or” includes any and all combinations of one or more of the associated listed items. In particular, references to “the / described” object or “an” object are also intended to indicate one of a plurality of possible such objects.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] Example 1

[0043] See Figures 1 to 4 The present invention discloses a multifunctional children's dining chair, including a support frame 1, a support seat 2, a seat body 3, a dining plate 4, and a linkage mechanism 5.

[0044] In this configuration, support frame 1 connects to and supports support base 2, while support base 2 connects to and supports base 3. Support frame 1 provides support to the ground, and support base 2 serves as the main structure supporting base 3. Support base 2 can also be used to install other components to fit base 3, or it can act as a counterweight. In some cases, support frame 1 may be used directly to connect to and support base 3, omitting support base 2. In this case, support frame 1 can be considered to serve the same function as support base 2, acting as the main structure supporting base 3.

[0045] The seat 3 includes a seat 8 and a backrest 9, which are pivotally connected. Since the backrest 9 can flip forward or backward relative to the seat 8, the seat 3 has a dining adjustable state and a reclining adjustable state. In the reclining adjustable state, the maximum adjustable angle M between the seat 8 and the backrest 9 is greater than the maximum adjustable angle N between the seat 8 and the backrest 9 in the dining adjustable state.

[0046] It should be noted that the angle between the seat 8 and the backrest 9 refers to the angle between the line connecting the front end of the seat 8 and the pivot point (the pivot point between the seat 8 and the backrest 9) and the line connecting the rear end of the backrest 9 and the pivot point (the pivot point between the seat 8 and the backrest 9). In the reclining adjustable position, the backrest 9 can be flipped forward or backward relative to the seat 8. There is no specific limit to the minimum angle between the seat 8 and the backrest 9 that can be achieved by flipping the backrest 9 forward, while the maximum angle between the seat 8 and the backrest 9 that can be achieved by flipping the backrest 9 backward is the adjustable maximum angle M. In the dining adjustable position, the backrest 9 can also be flipped forward or backward relative to the seat 8. There is also no specific limit to the minimum angle between the seat 8 and the backrest 9 that can be achieved by flipping the backrest 9 forward, but the maximum angle between the seat 8 and the backrest 9 that can be achieved by flipping the backrest 9 backward is only the adjustable maximum angle N.

[0047] Preferably, a multi-angle adjustment device 25 can be provided between the seat 8 and the backrest 9. The multi-angle adjustment device 25 can adjust the angle between the seat 8 and the backrest 9 to keep them at multiple angle positions to meet the usage requirements of different tilt angles. It should be noted that the innovation of this invention does not lie in the specific structure of the multi-angle adjustment device 25. The specific structure of the multi-angle adjustment device 25 can be any known one, and this invention does not limit the specific structure of the multi-angle adjustment device 25.

[0048] The plate 4 is detachably connected to the seat 8; the linkage mechanism 5 can be set on the seat 8 and can be linked and cooperated with the plate 4 and the back 9 respectively. The linkage mechanism 5 can be continuous with the plate 4 and the back 9, or it can be triggered only after certain conditions are met.

[0049] Importantly, when the tray 4 is connected and locked to the seat 8, the linkage mechanism 5 can restrict the seat 3 to the adjustable position. That is, the linkage mechanism 5 can restrict the angle between the seat 8 and the back 9 to be adjusted to the maximum adjustable angle N when the seat is adjustable, and it cannot exceed the maximum adjustable angle N to increase to the maximum adjustable angle M. When the tray 4 is unlocked and separated from the seat 8, the seat 3 is in the reclining adjustable position. That is, the linkage mechanism 5 allows the angle between the seat 8 and the back 9 to be increased to the maximum adjustable angle M when the seat is adjustable. At least when the angle between the seat 8 and the back 9 is greater than the maximum adjustable angle N, the linkage mechanism 5 can also prevent the tray 4 from being connected and locked to the seat 8.

[0050] It should be noted that the connection and locking between the plate 4 and the seat 8 means that after the plate 4 and the seat 8 are connected, a locking structure is still needed to lock the plate 4 and the seat 8 relative to each other to prevent the plate 4 from becoming loose and causing safety hazards. Of course, the innovation of this invention does not lie in the locking structure between the plate 4 and the seat 8; the locking structure can be any known type, and this invention does not limit it.

[0051] The EU standard for children's high chairs is for ages 6 to 36 months. EU standards for children's reclining chairs vary depending on the child's weight (under 9 kg), age (0-6 months), or age (0-12 months). The EU standard for testing the tip-over of children's high chairs is significantly higher than that for reclining chairs. In other words, the EU standard for tip-over testing when the seat (3) is in the adjustable seating position is much higher than the standard when the seat (3) is in the adjustable reclining position. This means that the angle between the seat (8) and back (9) in the adjustable reclining position would be difficult to pass under the EU standard for children's high chair tip-over testing.

[0052] Therefore, when the above invention connects and locks the tray 4 to the seat 8 to put the seat 3 in an adjustable dining position, the linkage mechanism 5 prevents the maximum angle between the seat 8 and the backrest 9 from increasing excessively, thus ensuring that it can pass the EU children's high chair tip-over test. When the tray 4 is unlocked and separated from the seat 8 to put the seat 3 in a reclining adjustable position, the linkage mechanism 5 allows the maximum angle between the seat 8 and the backrest 9 to increase to the maximum adjustable angle M. At the same time, the linkage mechanism 5 prevents the tray 4 from being locked to the seat 8, thus preventing it from entering the adjustable dining position. Therefore, at this time, it meets the EU safety test standards for children's reclining chairs. Yes, it is acceptable. Furthermore, since the seat 3 is in a reclining position and can be used for children aged 0 to 6 months, while in a dining position and can be used for children aged 6 to 36 months, the age limit for this feature prevents children older than 6 months from using the reclining position, ensuring their safety and overcoming the age restriction of 6 to 36 months for the high chair. Additionally, newborns have very weak lumbar support, so the larger the angle between the backrest 9 and the seat 8, the less support the newborn needs for their lower back. Therefore, newborns are more comfortable lying almost flat on the product, which is also more conducive to their healthy development. The invention provides a multifunctional children's dining chair with a seat 3 that can be adjusted for both a dining position and a reclining position. In the reclining position, the maximum adjustable angle M between the seat and back is greater than the maximum adjustable angle N between the seat and back in the dining position. The two adjustable positions can be switched by the coordinated action of the seat, the tray, and the linkage mechanism. This multifunctional children's dining chair has both dining chair functionality and a near-flat reclining function (in EU standards, non-bed products need a certain tilt angle and cannot achieve a 180-degree fully flat reclining function, so they only have a near-flat reclining function). As a result, it is a multifunctional children's dining chair that is suitable for children aged 0 to 36 months, has a longer service life, high cost performance, high safety performance, and better entertainment value.

[0053] See Figure 1 or Figure 2 In this embodiment, the multifunctional children's dining chair also includes an electric unit 10, which is mounted on the support base 2. The electric unit 10 drives the seat 3 to swing, so that the multifunctional children's dining chair has a dining chair function, a near-flat reclining function, and an electric rocking chair function, thereby improving entertainment and enhancing multifunctionality, resulting in a multifunctional children's dining chair with higher cost performance, stronger entertainment, and better meeting consumer needs.

[0054] Preferably, the multifunctional children's dining chair further includes a drive component 17. The first end of the drive component 17 is connected to the support seat 2, and the second end of the drive component 17 is locked or separated from the seat portion 8. When the drive component 17 is locked to the seat portion 8, the drive component 17 restricts the seat body 3 from swinging relative to the support seat 2, thereby locking the rocking chair function. More preferably, the first end of the drive component 17 is pivotally connected to the support seat 2 to improve the controllability of the drive component 17's movement.

[0055] Specifically, when the drive unit 17 is locked to the seat 8, the drive unit 17 can also drive the linkage mechanism 5 to restrict the seat 3 to the adjustable dining position and release the obstruction to the tray 4. In this way, when the rocking chair function is locked using the drive unit 17, the seat 3 is in the adjustable dining position, and when the rocking chair function is unlocked using the drive unit 17, the seat 3 is in the adjustable reclining position, ensuring its safety.

[0056] See Figures 3 to 6 In this embodiment, the linkage mechanism 5 includes a connector 11, a first linkage part 12, and a second linkage part 13. The first linkage part 12 is used to link with the plate 4, and the second linkage part 13 is used to link with the back 9. The first end of the connector 11 is connected to the first linkage part 12, and the second end of the connector 11 is connected to the second linkage part 13, so that the synchronous action between the first linkage part 12 and the second linkage part 13 can be realized through the connector 11.

[0057] Preferred options, please refer to Figure 7 and Figure 8 The seat 8 has a slot 14 for inserting a plate 4. The first linkage 12 includes a locking part 15, which is movably connected to the seat 8. The insert 20 in the locking part 15 can extend into or retract from the slot 14. The locking part 15 is also connected to the connector 11. Specifically, the locking part 15 includes a locking member 151, which is pivotally connected to the seat 8 and connected to the connector 11. The insert 20 is disposed on the locking member 151, and the locking member 151 can rotate relative to the seat 8 so that the insert 20 can extend into or retract from the slot 14.

[0058] Thus, when the drive member 17 is locked with the seat 8, the drive member 17 drives the second linkage part 13 to limit the rotation range of the backrest 9. At the same time, the second linkage part 13 drives the locking part 151 to rotate in the opposite direction through the connector 11, so that the insert 20 exits the slot 14 to allow the plate 4 to connect and lock with the seat 8, so that the seat 3 is in an adjustable dining position. When the second end of the drive member 17 is separated from the seat 8, the drive member 17 releases the restriction on the second linkage part 13, and then releases the restriction on the backrest 9. At this time, the locking part 151 rotates in the forward direction so that the insert 20 extends into the slot 14 to prevent the plate 4 from connecting and locking with the seat 8, so that the seat 3 is in a reclining adjustable position.

[0059] It should be noted that in some cases, the second linkage 13 releases the restriction on the back 9, and the locking member 151 rotates forward to allow the insert 20 to extend into the slot 14 to prevent the plate 4 from being locked to the seat 8. The two actions can be performed simultaneously. In other cases, the two actions can be performed sequentially (when the actions are sequential, the second linkage 13 may act first, or the locking member 151 may act first, which is not specifically limited).

[0060] In other embodiments, the locking member 151 may also be configured to move, swing, or rotate relative to the seat portion 8 along a specific track, and the locking member 151 may also drive the insert block 20 to extend into or exit the slot 14.

[0061] In other embodiments, the locking part 15 may also employ other known structures capable of driving the insert 20 into or out of the slot 14. For example, the locking part 15 may include an elastically deformable spring bar, the fixed end of which is connected to the seat 8, and the free end of which may be provided with the insert 20. The spring bar is also connected to the connecting member 11, and the two can drive each other. Alternatively, the locking part 15 may include a rotating wheel and a locking tongue, with the insert 20 disposed on the locking tongue. The rotating wheel is pivotally connected to the seat 8, and the locking tongue is slidably disposed on the seat 8. The rotating wheel is connected to the connecting member 11, and the two can drive each other. A rocker arm slider mechanism may be formed between the rotating wheel and the locking tongue, or the rotating wheel and the locking tongue may mesh. Other implementations will not be listed one by one. This embodiment does not limit the specific structure of the locking part 15. Any specific structure of the locking part 15 capable of driving the insert 20 into or out of the slot 14 can be considered within the scope of protection of this invention.

[0062] See Figure 4 and Figure 7 Specifically, the plate 4 is provided with a rod 19, which cooperates with the slot 14. When the insert block 20 is inserted into the slot 14, the insert block 20 can prevent the rod 19 from being inserted into the slot 14.

[0063] See Figure 7 and Figure 8 The linkage mechanism 5 also includes a reset part 21. When the reset part 21 drives the locking part 15 to reset, the insert 20 extends into the slot 14, so that the seat 3 is in a reclining adjustable state, thereby realizing the automatic reset of the reclining adjustable state. Specifically, the reset part 21 is a spring and is connected between the seat 8 and the locking part 15.

[0064] Of course, the reset part 21 can also be a torsion spring, a spring sheet, a reset linkage structure, a gravity reset counterweight structure, or other structures that can play a reset role. The invention does not limit the specific style or structure of the reset part 21.

[0065] See Figure 5 and Figure 6In this embodiment, the second linkage 13 includes a transmission member 16 and a blocking member 18. The blocking member 18 is connected to the back 9 and / or the seat 8. The transmission member 16 pivots with the seat 8. The transmission member 16 is also connected to the second end of the connector 11. The transmission member 16 can approach or separate from the blocking member 18 so as to restrict or allow the continued rotation of the back 9 through the blocking member 18. When the transmission member 16 approaches to restrict the blocking member 18, it can prevent the included angle between the seat 8 and the back 9 from being greater than the adjustable maximum included angle N.

[0066] Specifically, the blocking part 18 is fixedly connected to the back 9, so that the blocking part 18 rotates with the back 9. The transmission member 16 can come into contact with or separate from the blocking part 18 to limit or allow the continued rotation of the blocking part 18, thereby limiting or allowing the continued rotation of the back 9.

[0067] When the second end of the drive member 17 is locked with the seat 8, the second end of the drive member 17 drives the transmission member 16 to rotate, thereby driving the locking member 151 of the first linkage part 12 to rotate. The rotation of the locking member 151 causes the insert 20 to exit the slot 14 to allow the tray 4 to be connected and locked with the seat 8. At the same time, the transmission member 16, through the blocking part 18, ensures that the maximum angle between the backrest 9 and the seat 8 is only the maximum angle set between the seat 8 and the backrest 9 when the seat 3 is in the adjustable dining position (i.e., the maximum adjustable angle N), thereby ensuring that the seat 3 can pass the EU children's high chair tip-over test standard when it is in the adjustable dining position.

[0068] When the second end of the drive member 17 separates from the seat 8, the locking member 151 rotates to reset under the action of the reset member 21, and the transmission member 16 rotates back to its original position, so that the insert 20 extends into the slot 14, thereby preventing the plate 4 from being locked to the seat 8 and preventing the adjustable position from being formed. At the same time, after the transmission member 16 returns to its original position, it makes room for the blocking member 18 to rotate, so that the back 9 and the seat 8 form the same maximum angle as the maximum angle set between the seat 8 and the back 9 when the seat 3 is in the reclining adjustable position (i.e., the maximum adjustable angle M). Thus, the seat 3 is in the reclining adjustable position at this time.

[0069] In other embodiments, the blocking part 18 may also adopt other known structures that can cooperate with the transmission member 16 to limit the continued rotation of the back 9. For example, the blocking part 18 and the back 9 may form a rocker-slider mechanism, that is, one end of the blocking part 18 is pivotally connected to the back 9, and the other end of the blocking part 18 slides along a specific track on the seat 8. The transmission member 16 is used to adjust or obstruct the movement track of the blocking part 18 to limit the blocking part 18, thereby limiting the continued rotation of the back 9. Another example is that the blocking part 18 rotates relative to the seat 8 and the back 9 to form a seesaw structure. The transmission member 16 is used to adjust or obstruct the swing amplitude of the free end of the blocking part 18 to limit the blocking part 18, thereby limiting the continued rotation of the back 9. Yet another example is that the blocking part 18 is pivotally connected to the seat 8, and the blocking part 18 is provided with a block that can abut or disengage from the back 9. The transmission member 16 is used to adjust or obstruct the rotation amplitude of the blocking part 18 to limit the blocking part 18, thereby using the block on the blocking part 18 to limit the continued rotation of the back 9. Other implementation methods will not be listed one by one. This embodiment does not limit the specific structure of the blocking part 18. Any specific structure of the blocking part 18 that can cooperate with the transmission member 16 to limit the continued rotation of the back 9 can be regarded as the protection scope of the present invention.

[0070] To better understand the principles of this invention, please refer to... Figure 7 and Figure 8 Referring to the direction shown, as a specific example, the connector 11 can be a pull rope. The transmission member 16 is L-shaped and includes a horizontal arm 161 and a vertical arm 162 fixedly connected to each other. The corner where the horizontal arm 161 and the vertical arm 162 connect is pivotally connected to the seat 8. The blocking part 18 is hook-shaped and fixedly connected to the pivot of the back 9. When the driving member 17 rotates counterclockwise so that its second end hooks onto the seat 8 to complete the locking, the second end of the driving member 17 will press down against the end of the horizontal arm 161 of the transmission member 16. The transmission member 16 rotates clockwise so that the vertical arm 161 of the transmission member 16... When the backrest 9 is tilted backward to increase the angle between the seat 8 and the backrest 9 to the maximum adjustable angle N, the end of the vertical arm 162 hooks onto the blocking part 18 to restrict the backrest 9 from tilting backward further. The vertical arm 162 of the transmission member 16 pulls the connecting member 11, which in turn pulls the locking member 151 to rotate counterclockwise. The locking member 151 causes the insert 20 to exit the slot 14, allowing the insert rod of the plate 4 to be inserted into the slot 14, thus locking the connection between the plate 4 and the seat 8. The seat 3 is then in an adjustable position. Conversely, when the plate 4 is removed and the drive member 17 is rotated clockwise to unlock the seat 8, the transmission member 16, the locking member 151, and the insert 20 reset or return to their original positions, allowing the backrest 9 to continue tilting backward and preventing the connection between the plate 4 and the seat 8 from locking. This puts the seat 3 in a reclining adjustable position, and the seat 3 can be driven by the electric unit 10 to swing.

[0071] It should be noted that in this embodiment, when switching from the reclining adjustable state to the dining adjustable state, the back 9 needs to be flipped forward so that the angle between the seat 8 and the back 9 is equal to or less than the maximum adjustable angle N, so that the blocking part 18 can make room for the transmission member 16 to rotate, and then the insert 20 can exit the slot 14.

[0072] In summary, the multifunctional children's dining chair of the present invention has both a dining chair function and a near-flat reclining function, and can also achieve electric swing when in the near-flat reclining function. It is suitable for children from 0 to 36 months and meets the side roll test standard requirements in different applicable scenarios. It has high cost performance and good entertainment value.

[0073] Example 2

[0074] See Figures 9 to 12 This embodiment also discloses a multifunctional children's dining chair, which also includes a support frame 1, a support seat 2, a seat body 3, a tray 4, a linkage mechanism 5, an electric unit 10, a drive unit 17, and a multi-position angle adjustment device 25. The seat body 3 also includes a seat part 8 and a backrest 9. The seat part 8 is also provided with a slot 14, and the tray 4 is also provided with a plug 19. The only difference between the multifunctional children's dining chair in this embodiment and the multifunctional children's dining chair in embodiment 1 is the different linkage mechanism 5.

[0075] In this embodiment, the linkage mechanism 5 includes a movable part 22, a reset part 21, and a blocking part 18. The movable part 22 is movably disposed relative to the seat part 8. The movable part 22 is used to work in conjunction with the plate 4 and the blocking part 18. The blocking part 18 is connected to the backrest 9 and / or the seat part 8. The movable part 22 can be close to or separate from the blocking part 18 so as to restrict or allow the backrest 9 to continue rotating. When the reset part 21 drives the movable part 22 to reset, the movable part 22 prevents the plate 4 from being inserted into the seat part 8 and allows the backrest 9 to continue rotating, so that the seat 3 is in a reclining adjustable state.

[0076] Specifically, the blocking part 18 is fixedly connected to the back 9, so that the blocking part 18 rotates with the back 9. The movable part 22 includes a moving member 23, which is slidably disposed on the seat part 8. The moving member 23 can approach or separate from the blocking part 18 to limit or allow the continued rotation of the blocking part 18, thereby limiting or allowing the continued rotation of the back 9.

[0077] Specifically, the movable member 23 is tilted and slidably mounted on the seat 8, and the reset part 21 is a spring connected between the seat 8 and the movable member 23. The reset part 21 provides a drive for the movable member 23 to tilt upward and slide back to its original position.

[0078] In other embodiments, the movable member 23 may also be moved, swung, or rotated relative to the seat 8 along a specific track, and the movable member 23 may also drive the insert 20 to extend into or out of the slot 14.

[0079] In other embodiments, the movable part 22 may also adopt other known structures capable of driving the insert 20 to extend into or exit the slot 14. For example, the movable part 22 may include a moving member 23 and a rotating rod. The moving member 23 is movably disposed on the base 8, and the rotating rod is pivotally connected to the base 8. The insert 20 is provided on the rotating rod. One end of the moving member and the rotating rod are connected by a transmission. When the moving member 23 moves, it drives the rotating rod to swing, and the rotating rod drives the insert 20 to swing into or out of the slot 14. Another example is that the movable part 22 may include a moving member 23 and a gear. The moving member 23 is movably disposed on the base 8, and the gear is rotatably connected to the base 8. The moving member 23 and the gear mesh, and the insert 20 is disposed on the gear. When the moving member 23 moves, it drives the gear to rotate, and the gear drives the insert 20 to rotate into or out of the slot 14. Other implementation methods will not be listed one by one. This embodiment does not limit the specific structure of the movable part 22. Any specific structure of the movable part 22 capable of driving the insert 20 to extend into or out of the slot 14 can be considered within the scope of protection of this invention.

[0080] Similar to Embodiment 1, the blocking part 18 can also adopt other known structures that can cooperate with the movable part 22 to limit the continued rotation of the back 9. For example, the blocking part 18 and the back 9 can also form a rocker-slider mechanism, that is, one end of the blocking part 18 is pivotally connected to the back 9, and the other end of the blocking part 18 slides along a specific track on the seat 8. The movable part 22 is used to adjust or obstruct the movement track of the blocking part 18 to limit the blocking part 18, thereby limiting the continued rotation of the back 9. Another example is that the blocking part 18 rotates relative to the seat 8 and the back 9 to form a seesaw structure. The movable part 22 is used to adjust or obstruct the swing amplitude of the free end of the blocking part 18 to limit the blocking part 18, thereby limiting the continued rotation of the back 9. Yet another example is that the blocking part 18 is pivotally connected to the seat 8, and the blocking part 18 is provided with a block that can abut or disengage from the back 9. The movable part 22 is used to adjust or obstruct the rotation amplitude of the blocking part 18 to limit the blocking part 18, thereby using the block on the blocking part 18 to limit the continued rotation of the back 9. Other implementation methods will not be listed one by one. This embodiment does not limit the specific structure of the blocking part 18. Any specific structure of the blocking part 18 that can cooperate with the movable part 22 to limit the continued rotation of the back 9 can be regarded as the protection scope of the present invention.

[0081] Similar to Embodiment 1, the reset part 21 can also be a torsion spring, a spring sheet, a reset linkage structure, a gravity reset counterweight structure, or other structures that can perform the reset function. The present invention does not limit the specific style or structure of the reset part 21.

[0082] In the above scheme, when the tray 4 is removed to unlock and separate the tray 4 from the seat 8, the tray 4 no longer obstructs the moving part 23. Under the reset action of the reset part 21, the moving part 23 moves and separates from the blocking part 18. After the moving part 23 is reset, it makes room for the blocking part 18 to rotate, allowing the blocking part 18 to continue to rotate. This allows the backrest 9 and the seat 8 to form the same maximum angle as the maximum angle set between the seat 8 and the backrest 9 when the seat 3 is in the reclining adjustable state (i.e., the maximum adjustable angle M). Thus, the seat 3 is in the reclining adjustable state at this time. When the tray 4 is connected and locked to the seat 8, the tray 4 drives the moving part 23 to move, so that the moving part 23 is close to and restricts the continued rotation of the blocking part 18. This ensures that the maximum angle between the backrest 9 and the seat 8 is only the maximum angle set between the seat 8 and the backrest 9 when the seat 3 is in the dining adjustable state (i.e., the maximum adjustable angle N). This ensures that the seat 3 can pass the EU children's high chair tip-over test standard when it is in the dining adjustable state.

[0083] Preferably, the seat 8 is provided with a slot 14 for inserting a plate 4. One end of the movable member 23 is provided with a stop 24 that extends into or retracts from the slot 14. When the plate 4 is inserted into the slot 14, the plate 4 can push the stop 24 to retract from the slot 14. The stop 24 drives the movable member 23 to move, so that the other end of the movable member 23 is close to restrict the continued rotation of the blocking part 18, so that the seat 3 is in an adjustable position. Specifically, the insertion rod 19 of the plate 4 is used to insert into the slot 14 and push against the stop 24. A pushing slope can be provided on the stop 24 or the insertion rod 19 to better bear the pushing force. When the insertion rod 19 pushes against the stop 24, it overcomes the reset force of the reset part 21. When the insertion rod 19 disengages from the slot 14, the reset part 21 drives the movable member 23 to reset and causes the stop 24 to re-insert into the slot 14.

[0084] Thus, no additional structure is needed to drive the movement of the moving part 23; only the cooperation between the plate 4 and the stop 24 is required. Compared with the multifunctional children's dining chair of Embodiment 1, its structure is simpler, and its operation is more convenient and durable.

[0085] Preferably, when the reset part 21 drives the moving part 23 to reset and the included angle between the seat part 8 and the back 9 is greater than the maximum adjustable included angle N, the blocking part 18 can be used to abut the moving part 23 to prevent the stop block 24 from exiting the slot 14. At this time, the insert rod 19 of the plate 4 cannot push the stop block 24, thereby preventing the plate 4 from being locked to the seat part 8, so that it cannot form an adjustable dining position.

[0086] Additionally, it should be noted that features not described in detail in this embodiment can be referred to the relevant description in Embodiment 1, and will not be repeated in this embodiment.

[0087] In this embodiment, the moving part 23 may not be linked with the driving part 17.

[0088] To better understand the principles of this invention, please refer to... Figure 11 and Figure 12 Taking the direction shown as a reference, as a specific example, during the process of inserting the rod 19 of the plate 4 into the slot 14, the rod 19 moves to the right, pushing the stop 24. The stop 24 drives the moving part 23 to tilt downward to the right. The moving part 23 compresses the reset part 21, and the lower end of the moving part 23 presses against the blocking part 18, preventing the blocking part 18 from continuing to rotate clockwise. This prevents the backrest 9 from rotating downward, thus preventing the angle between the backrest 9 and the seat 8 from increasing. It can only maintain the maximum adjustable angle N in the adjustable dining position, and cannot increase to the maximum adjustable angle M in the adjustable reclining position. Thus, the seat 3 is in the adjustable dining position at this time, which can pass EU testing and ensure consumer safety. When the rod 19 is pulled out to the left, the rod 19 disengages from the stop 24. The reset part 21 drives the moving part 23 to tilt the stop 24 upward to the left to reset, so that the stop 24 extends... The lower end of the movable member 23 is inserted into the slot 14, allowing the blocking part 18 to rotate. The blocking part 18 can continue to rotate clockwise, allowing the backrest 9 to rotate downwards. This increases the angle between the backrest 9 and the seat 8 to the maximum adjustable angle M in the adjustable seating position, thus placing the seat 3 in a reclining adjustable position. When the angle between the seat 8 and the backrest 9 is greater than the maximum adjustable angle N, the blocking part 18 is close to the lower end of the movable member 23, preventing the movable member 23 from moving downwards. This prevents the plate 4 from being inserted into the seat 8 and locks it in the adjustable seating position for use as a dining chair. If the adjustable seating position is to be used as a dining chair, the angle between the seat 8 and the backrest 9 must be reduced to the maximum adjustable angle N in the adjustable seating position. This allows the blocking part 18 to make room for the lower end of the movable member 23 to move downwards, causing the stop block 24 to exit the slot 14. Only then can the plate 4 be inserted into the seat 8 for use as a dining chair.

[0089] In this embodiment, it should be noted that the multifunctional children's high chair in this embodiment is the same as the multifunctional children's high chair in embodiment 1: the seat 3 has both an adjustable dining position and an adjustable reclining position. In the reclining position, the maximum adjustable angle M between the seat and the back is greater than the maximum adjustable angle N between the seat and the back in the dining position. The switching between the two adjustable positions can be controlled by the coordinated action of the seat, the tray, and the linkage mechanism. This makes the multifunctional children's high chair both a dining chair and a near-reclining function, thus becoming a multifunctional children's high chair that is suitable for children aged 0 to 36 months, has a longer usage time, high cost performance, high safety performance, and better entertainment.

[0090] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
