Detailed Implementation

[0029] In related technologies, there are many types of tableside dining chairs, most of which are fixed by threads, making the operation process relatively cumbersome and unable to be easily and quickly installed and disassembled.

[0030] This utility model provides a tableside dining chair with a simple structure that can be quickly and smoothly installed and unlocked, in order to solve the problem that the installation process of existing tableside dining chairs is cumbersome and cannot be completed quickly.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 10 The table chair 100 according to an embodiment of the present invention includes: a support seat 10, a lower clamping arm 20, and a height adjustment mechanism 30. The support seat 10 can be used for infants to sit on, the lower clamping arm 20 can cooperate with the support seat 10 to clamp the tabletop, and the height adjustment mechanism 30 can drive the lower clamping arm 20 to move up and down so that the lower clamping arm 20 can clamp and release the tabletop from the support seat 10.

[0033] Specifically, the support base 10 includes a base body 11, an upper clamping arm 12, and a support arm 13. The upper clamping arm 12 is connected to the base body 11 and extends forward, while the support arm 13 is connected to the upper clamping arm 12 and extends downward. The lower clamping arm 20 has a lower clamping portion located below the upper clamping arm 12. The lower clamping arm 20 is movable in the vertical direction and is used to engage with the upper clamping arm 12 to clamp and release the desktop plate located between the lower clamping portion and the upper clamping arm 12. A height adjustment mechanism 30 is connected to the support arm 13 and is used to drive the lower clamping arm 20 to move in the vertical direction.

[0034] According to the embodiment of the present utility model, the tableside dining chair 100 can use the height adjustment mechanism 30 to drive the lower clamping arm 20 to move up and down, avoiding the problem that the upper clamping arm 12 and the lower clamping part are difficult to clamp the tabletop due to manually driving the lower clamping arm 20 to move, thereby improving the clamping effect of the tableside dining chair 100 on the tabletop and improving the stability and safety of the tableside dining chair 100.

[0035] In use, the tableside dining chair 100 of this utility model can have its upper clamping arm 12 supported on the upper surface of the tabletop, with the lower clamping part positioned below the tabletop. The height adjustment mechanism 30 drives the lower clamping arm 20 upwards. When the lower clamping arm 20 reaches the appropriate position, it abuts against the lower surface of the tabletop. At this point, the cooperation of the upper clamping arm 12 and the lower clamping part clamps the tabletop. Because the lower clamping arm 20 is moved by the height adjustment mechanism 30, the upper clamping arm 12 and the lower clamping part can stably clamp the tabletop. When the tableside dining chair 100 needs to be removed from the tabletop, the height adjustment mechanism 30 can be used to unlock the lower clamping arm 20. The lower clamping arm 20 can then move downwards, releasing the clamping part from the upper clamping arm 12's grip on the tabletop, allowing the tableside dining chair 100 to be removed.

[0036] Optionally, the height adjustment mechanism 30 in this utility model can be configured to drive the lower clamping arm 20 in both directions, that is, to drive the lower clamping arm 20 to move upward and downward; the height adjustment mechanism 30 can also be configured to drive the lower clamping arm 20 to move upward in one direction.

[0037] like Figures 3 to 6 In some embodiments, the height adjustment mechanism 30 includes a mounting base 31, a one-way drive assembly 32, and an unlocking member 33. The one-way drive assembly 32 is configured to drive the lower clamping arm 20 to move upward, and the one-way drive assembly 32 can also restrict the lower clamping arm 20 from moving downward. The unlocking member 33 is configured to release the restriction imposed by the one-way drive assembly 32 on the downward movement of the lower clamping arm 20. The one-way drive assembly 32 can drive the lower clamping arm 20 to move upward, so that the lower clamping part and the upper clamping arm 12 can cooperate to clamp the tabletop, avoiding accidental operation of the one-way drive assembly 32 that would cause the lower clamping arm 20 to move downward, thus ensuring the stability of the dining chair 100 after the lower clamping part and the upper clamping arm 12 clamp the tabletop. The unlocking member 33 can release the downward movement of the lower clamping arm 20. After the unlocking member 33 is unlocked, the lower clamping arm 20 can move downward, thereby releasing the lower clamping part and the upper clamping arm 12 from clamping the tabletop, making it convenient to remove the dining chair 100 from the tabletop.

[0038] The height adjustment mechanism 30 in this invention can be configured to lock and unlock the downward movement of the lower clamping arm 20. When the height adjustment mechanism 30 locks the downward movement of the lower clamping arm 20, the lower clamping arm 20 will not move downward. When the lower clamping arm 20 and the upper clamping arm 12 cooperate to clamp the tabletop, the downward movement of the lower clamping arm 20 is locked, which facilitates the lower clamping part and the upper clamping arm 12 to stably clamp the tabletop. In addition, when the height adjustment mechanism 30 unlocks the downward movement of the lower clamping arm 20, the lower clamping arm 20 can move downward. When it is necessary to remove the table chair, unlocking the lower clamping arm 20 can facilitate the downward movement of the lower clamping arm 20, thereby releasing the clamping of the lower clamping arm 20 and the upper clamping arm 12 on the tabletop, so that the table chair 100 can be removed from the tabletop.

[0039] The one-way drive component 32 in this invention can take different forms, such as a ratchet 321 mechanism, a one-way clutch mechanism, or a one-way bearing mechanism. Figure 4 and Figure 5In some embodiments of this utility model, the unidirectional drive assembly 32 may include a ratchet 321 and a ratchet tooth 322. The mounting base 31 is connected to the support arm 13. The ratchet 321 is rotatably connected to the mounting base 31, and the ratchet tooth 322 is connected to the mounting base 31 and can disengage from the ratchet 321 to restrict the unidirectional rotation of the ratchet 321. When the ratchet 321 rotates in the first direction, the ratchet tooth 322 can disengage from the teeth of the ratchet 321, so that the ratchet 321 can rotate in the first direction. At this time, the height adjustment mechanism 30 drives the lower clamping arm 20 to move upward. When the ratchet 321 has a tendency to rotate in the opposite second direction, the ratchet tooth 322 will restrict the rotation of the ratchet 321, thereby restricting the height adjustment mechanism 30 from driving the lower clamping arm 20 to move upward. By adopting a ratchet 321 and ratchet 322 structure, the height adjustment mechanism 30 can easily drive the lower clamping arm 20 to move upward in one direction. When the lower clamping part and the upper clamping arm 12 cooperate to clamp the tabletop, the limiting effect of the ratchet 322 can lock the lower clamping arm 20 and restrict the lower clamping arm 20 from moving downward, thereby improving the stability of the lower clamping part and the upper clamping arm 12 in clamping the tabletop.

[0040] Among them, such as Figure 4 and Figure 5 The unlocking element 33 is movably connected to the seat 11 and is used to drive the ratchet 322 to disengage from the ratchet 321. By using the unlocking element 33 to drive the ratchet 322 to disengage from the ratchet 321, the restriction on the ratchet 321's rotation in the second direction is released. At this time, under the weight of the lower clamping arm 20 or manual drive, the lower clamping arm 20 will disengage from the position holding the tabletop, releasing the clamp on the tabletop, so that the dining chair 100 can be removed from the tabletop. Figure 5 As shown, the unlocking component 33 drives the ratchet 322 to disengage from the ratchet 321.

[0041] One end of the ratchet 322 is rotatably connected to the mounting base 31, and the unlocking member 33 is opposite to the other end of the ratchet 322, and can drive the ratchet 322 to disengage from the teeth of the ratchet 321. The teeth of the ratchet 322 are located on the side close to the ratchet 321 between the two ends.

[0042] As shown in the figure, in some embodiments, the bottom of the mounting base 31 is provided with a clearance hole 3101, the ratchet 322 is connected to the upper part of the mounting base 31, and the unlocking member 33 is movably connected to the mounting base 31 in the vertical direction. The upper end of the unlocking member 33 is opposite to the ratchet 322, and the lower end of the unlocking member 33 is opposite to the clearance hole 3101. When it is necessary to use the unlocking member 33 to drive the ratchet 322 out of engagement with the ratchet 321, the unlocking member 33 can be driven from the clearance hole 3101, which is convenient to operate. Moreover, the clearance hole 3101 is located at the bottom of the mounting base 31, near the outer side of the desktop, which allows the user to easily touch and drive the unlocking member 33, making it convenient to use.

[0043] Combination Figures 3 to 5 In some embodiments, the height adjustment mechanism 30 further includes a knob 34, which is rotatably connected to the mounting base 31 and is drively connected to a ratchet 321 to drive the ratchet 321 to rotate. The knob 34 can be used to drive the ratchet 321 to rotate. The outer peripheral surface of the knob 34 can be provided with a structure such as a rib to increase the friction between the hand and the knob 34, so as to facilitate manual driving of the knob 34 to rotate.

[0044] The knob 321 is provided with at least two first positioning pins and at least two first positioning holes. The at least two first positioning pins are arranged around the rotation center axis of the knob 34, and the at least two first positioning pins are respectively inserted through the at least two first positioning holes, so as to realize the stable driving of the knob 34 on the first positioning pins.

[0045] In addition, the mounting base 31 of this utility model may include a housing and a cover. The housing has a storage space, and the lower clamping arm 20 and the rack pass through the storage space. The housing is open on one side in the left-right direction. The cover covers the open side of the housing and has a hole for accommodating the ratchet 321. One of the cover and the housing has at least two second positioning pins arranged around the rotation center axis of the ratchet 321. The other of the cover and the housing has at least two second positioning holes arranged around the rotation center axis of the ratchet 321. The at least two second positioning pins pass through the at least two second positioning holes respectively to achieve a stable connection between the cover and the housing.

[0046] The height adjustment mechanism 30 in this invention can be configured to drive the lower clamping arm 20 to rise and fall using belt drive or gear drive, etc. Figure 6 In some embodiments of this utility model, the height adjustment mechanism 30 further includes a drive gear 341 and a transmission rack 342. The drive gear 341 is connected to a ratchet 321, and the transmission rack 342 extends in the vertical direction and connects to the lower clamping arm 20. The transmission rack 342 meshes with the drive gear 341. This enables the height adjustment mechanism 30 to stably drive the lower clamping arm 20. Moreover, when the lower clamping arm 20 and the upper clamping arm 12 are engaged to clamp the tabletop, the gear and rack transmission mechanism can maintain the clamping force of the lower clamping arm 20 and the upper clamping arm 12 on the tabletop, thus maintaining the stability of the dining chair 100.

[0047] Optionally, the drive gear 341 can be configured to be coaxial with the ratchet 321, and the pitch circle radius of the drive gear 341 can be configured to be smaller than the radius of the ratchet 321. Preferably, the pitch circle radius of the drive gear 341 is not greater than half the radius of the ratchet 321, so as to further improve the stability of the gear rack structure and achieve stable clamping when the lower clamping arm 20 and the upper clamping arm 12 cooperate to clamp the desktop plate.

[0048] The lower clamping arm 20 can be configured as a square tube, with mounting holes on its side. These mounting holes can be elongated strips extending vertically. A portion of the rack is located within the lower clamping arm 20, with the teeth of the rack extending from the mounting holes. The upper and lower ends of the rack abut against the upper and lower edges of the mounting holes. The rack has a first mating hole, and the lower clamping arm 20 has a second mating hole. The first and second mating holes are opposite each other and are connected together by screws, pins, or rivets. The mounting base 31 has arc-shaped ribs and reinforcing ribs. The arc-shaped ribs surround the placement space, and the gear is located within the placement space. One side of the arc-shaped ribs has an opening for the gear teeth to extend and mesh with the rack. The reinforcing ribs connect the arc-shaped ribs to the side wall of the mounting base 31.

[0049] like Figure 2 In some embodiments, the support arm 13 includes a connecting arm 131 and an extension arm 132. The connecting arm 131 extends vertically, and its upper end is connected to the upper clamping arm 12. The extension arm 132 is connected to the lower end of the connecting arm 131 and extends forward. A height adjustment mechanism 30 is provided on the extension arm 132. This can increase the distance between the clamping position of the lower clamp and the lower clamping arm 20 and the edge of the desktop, thereby achieving stable clamping of the desktop by the lower clamp and the upper clamping arm 12.

[0050] The connecting arm 131 and the extension arm 132 can be designed with a rounded transition to avoid stress concentration at the connection between the connecting arm 131 and the extension arm 132. Furthermore, the connecting arm 131 and the extension arm 132 can be designed as tubular, and the connecting arm 131 and the extension arm 132 can be designed as a straight tube bent to further improve the structural strength of the support arm 13.

[0051] In addition, such as Figure 7 and Figure 8 The upper clamping arm 12 may include two arms distributed along the left-right direction. The upper clamping arm 12 may include an upper tube 121. The support seat 10 may also include a connecting tube 14, which extends along the left-right direction and is arc-shaped. The left upper tube 121 extends along the front-back direction and its rear end connects to the left end of the connecting tube 14. The right upper tube 121 extends along the front-back direction and its rear end connects to the right end of the connecting tube 14. The seat body 11 connects to the rear half of the upper clamping arm 12 and has a seating space. The left upper tube 121, the connecting tube 14, and the right upper tube 121 are arranged around the seating space. The front half of the upper clamping arm 12 is used to cooperate with the lower clamping part to clamp the desktop.

[0052] Additionally, the support arm 13 may include two distributed on the left and right sides. The upper end of the left support arm 13 is connected to the upper clamping arm 12 on the left side, and the upper end of the right support arm 13 is connected to the upper clamping arm 12 on the right side. The height adjustment mechanism 30 and the lower clamping arm 20 each include two distributed on the left and right sides. The height adjustment mechanism 30 on the left side is connected to the front end of the left support arm 13, and the lower clamping arm 20 on the left side extends in the vertical direction and passes through the height adjustment mechanism 30 on the left side. The height adjustment mechanism 30 on the right side is connected to the front end of the right support arm 13, and the lower clamping arm 20 on the right side extends in the vertical direction and passes through the height adjustment mechanism 30 on the right side.

[0053] like Figure 9 In some embodiments, the lower clamping arm 20 further includes a telescopic rod 21, which extends vertically and is movably threaded through the height adjustment mechanism 30 in the same direction. The lower clamping part is connected to the upper end of the telescopic rod 21. The telescopic rod 21 extends vertically, so that when the lower clamping part cooperates with the upper clamping arm 12 to clamp the desktop, the reaction force on the lower clamping part is directed downwards and directly transmitted to the height adjustment mechanism 30. This reduces the torque force on the lower clamping arm 20, improves clamping stability, and avoids stress concentration.

[0054] The lower clamping arm 20 may include a first connecting part 22, which is connected to the upper end of the telescopic rod 21. The telescopic rod 21 may be configured as a tubular structure extending in the vertical direction. The first connecting part 22 may include a connecting rod and a support plate. The connecting rod may be configured to pass through the upper end of the telescopic tube, and the support plate may be connected to the upper end of the connecting rod. The lower clamping part may be installed on the support plate to further improve the clamping stability.

[0055] Combination Figure 2 , Figure 8 as well as Figure 9 In some embodiments, the lower clamping portion includes a first flexible block 23, and the upper clamping arm 12 includes a second flexible block 123. The first flexible block 23 and the flexible block cooperate to clamp the desktop panel. This can further improve the holding force of the lower clamping portion and the upper clamping arm 12 on the desktop panel.

[0056] The upper clamping arm 12 may include an upper tube body 121, a tube cover 122, and a second flexible block 123. The tube cover 122 covers the upper side of the front half of the upper tube body 121, and the second flexible block 123 is connected to the lower part of the upper tube body 121. The tube cover 122 and the second flexible block 123 cooperate to wrap the front half of the upper tube body 121. The first flexible block 23 is connected to the upper end of the upper clamping arm 12 and is opposite to the second flexible block 123 in the vertical direction.

[0057] like Figure 10In some embodiments, the table chair 100 also includes a tray 40, which is connected to the clamp arm 12. The tray 40 may be configured to hold tableware, food, or toys to facilitate play or eating for children sitting in the table chair 100.

[0058] The upper surface of the tray 40 may be provided with a placement slot, which may include a larger first placement slot and a smaller second placement slot. The first placement slot may be generally square, and the second placement slot may be located on the front left or front right side of the first placement slot for easy placement of cups.

[0059] The tableside dining chair 100 of this utility model has a double-sided locking structure. The lower clamping part is moved upward by the extension and retraction of the lower clamping arm 20, so as to be installed on the table. The tableside dining chair 100 can be unlocked by simply pressing the unlocking part 33.
