Description

Technical Field

[0001] This utility model relates to a highly stable fixed baby table chair, belonging to the technical field of baby table chairs. Background Technology

[0002] As a portable device to assist infants and toddlers with eating and activities, baby table chairs have become increasingly popular in homes and public places in recent years. Their core function is to provide infants with an independent and safe space for eating or playing, while allowing parents to supervise them at the table. With the upgrading of parenting concepts and the improvement of purchasing power, the market demand for baby table chairs has gradually expanded from a single function to multiple dimensions such as safety, stability, and convenience. Existing products mostly adopt a foldable design to adapt to different table sizes and use fixing devices to connect the chair to the edge of the table to prevent accidental sliding or tipping. However, due to the dynamic impact forces generated by infants' activities, coupled with the complexity of different family usage scenarios (such as differences in table thickness and materials), achieving high stability has become a design challenge. Furthermore, the fixing method of baby table chairs must also consider requirements such as quick assembly and disassembly, ease of operation, and no damage to the table surface, which poses even greater challenges to structural design and material selection.

[0003] Currently, baby table and chair fixing solutions on the market mainly fall into three categories: clamp-on, suction cup, and support frame. Clamp-on fixing uses mechanical clamps to secure the tabletop edge. Its advantage lies in its adaptability to various tabletop thicknesses, but it suffers from insufficient clamping force or uneven force distribution at the clamping points, making it prone to shaking or even falling off due to baby movement. Suction cup fixing relies on vacuum adsorption, allowing for quick installation without damaging the tabletop. However, its adsorption stability is limited by ambient temperature, tabletop flatness, and material (such as wood or glass), and it is prone to failure due to air leakage after long-term use. Support frame fixing utilizes a support structure extending to the bottom of the table to create reverse support. The length of the support is adjusted to match the tabletop height, but this design is often bulky, lacks portability, and the adjustment process is cumbersome, making it difficult to meet the needs of quick assembly and disassembly. Furthermore, existing fixing devices mostly use rigid connections, lacking a buffering mechanism against dynamic impacts. Long-term use can easily lead to wear or deformation of connecting parts, further reducing stability.

[0004] Regarding the aforementioned existing technologies, the inventors found that clamp-type fixation has a limited clamping range and poor adaptability to irregularly shaped tabletops (such as curved edges) or ultra-thin / ultra-thick tabletops. Furthermore, the clamping force is overly dependent on the user's operating force, easily leading to safety hazards due to improper installation. Secondly, suction cup fixation is greatly affected by environmental factors, especially when there are temperature changes or oil or water stains on the tabletop, causing a sharp decrease in suction force, which cannot meet the needs of high-dynamic load scenarios. Thirdly, while support frame fixation can provide a larger support area, the support structure is bulky, occupies space under the table, affects the user's leg movement, and the adjustment mechanism is prone to jamming or loosening due to frequent operation. More importantly, existing fixation devices generally lack vertical adjustability and elastic buffer design, resulting in the fixation point not adaptively fitting the tabletop contact surface. This can easily cause instantaneous displacement or resonance when the infant suddenly moves, exacerbating instability. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a highly stable fixed baby table chair.

[0006] The technical solution for a highly stable, fixed baby table chair provided in this application is as follows: A highly stable fixed baby table chair includes: Seat body; A tray, which is disposed on one side of the seat body and fixedly connected to the seat body; A desktop mounting bracket is provided with a fixing member, at least a portion of which is located below the tray. The fixing member can move along the vertical direction of the tray to fix the tray to the desktop.

[0007] Through the above technical solution, this application discloses a highly stable fixed baby table chair. This application features a vertical adjustment function for the fixing components, achieved through threads, springs, or sliding rail mechanisms, ensuring uniform force distribution between the tray and the tabletop contact surface, avoiding the stress concentration problem of traditional single-point clamping. This design significantly improves stability, especially reducing the risk of lateral displacement during infant movement, while also being compatible with tabletops of different structures, solving the problem of poor adaptability of existing clamping devices. Furthermore, the integrated fixing design of the tray and seat body reduces structural complexity, enhances overall rigidity, and provides a safer dining environment for infants.

[0008] Furthermore, the desktop fixing bracket is provided in two parts and is positioned opposite each other on one side of the seat body.

[0009] The above technical solution further limits the number and layout of the desktop fixing brackets, clearly defining two symmetrically distributed brackets on one side of the seat body to form a dual-support point fixing structure. The symmetrical layout of the dual brackets distributes the load through the principle of mechanical balance. For example, when an infant applies lateral force, the two brackets can work together to counteract torque, improving anti-tipping capability compared to a single bracket. Simultaneously, the dual-point support allows adaptation to desktop edges of different widths; by adjusting the distance between the two brackets, the table edge size can be flexibly matched, avoiding clamping failure caused by excessively wide desktops in traditional single-bracket designs. This design also reduces the pressure on individual fixing components by distributing the load, extending component lifespan. The mechanical optimization of the symmetrical layout makes it particularly suitable for highly dynamic usage scenarios.

[0010] Furthermore, each of the desktop mounting brackets includes: A connecting rod, which is formed as a rod-shaped component and has one end detachably connected to the seat body and the other end detachably connected to the tray; The support rod is formed in the form of a U-shaped rod, one end of which is fixedly connected to the connecting rod, and the other end of which is fixedly connected to the fixing member.

[0011] Through the above technical solution, this application optimizes the composition of the desktop mounting bracket, including a detachable connecting rod and a U-shaped support rod. The two ends of the connecting rod are detachably connected to the seat body and tray, respectively, facilitating quick assembly, disassembly, and storage. One end of the U-shaped support rod is fixed to the connecting rod, and the other end is connected to a fixing component. Its closed-section design enhances bending stiffness, effectively resisting cyclic loads generated by infant movement. The U-shaped structure also forms a stable triangular mechanical frame, directly transferring the force of the tray to the desktop, reducing the risk of seat body deformation. The modular design balances portability and strength; the detachable support rod can be cleaned or replaced individually without disassembling the entire seat, solving the problem of inconvenient maintenance of traditional integrated brackets. This structure is particularly suitable for scenarios requiring frequent handling or storage.

[0012] Furthermore, the fastener includes: A fixed sleeve, at least a portion of which is located at the end of the support rod and is formed as a tubular component with open ends, wherein the inner wall surface of the fixed sleeve is provided with an internal thread extending in its axial direction. A fixing rod, at least a portion of which is disposed inside the fixing sleeve and its outer circumferential surface is provided with an external thread that mates with the internal thread on the fixing sleeve, and the internal thread and the external thread are provided with an axial clearance after they are engaged. An elastic element, which is a spring, is sleeved on the fixed rod and disposed within the axial clearance.

[0013] Through the above technical solution, this application further optimizes the mechanical structure of the fastener. The fixing sleeve is installed at the end of the support rod, and the fixing rod is screwed into the sleeve by threads to achieve vertical height adjustment. The spring fills the thread gap to provide axial buffering, while the preload automatically compensates for loosening caused by vibration. This design combines the precise locking of the threads with the dynamic buffering of the spring, ensuring clamping stability while avoiding damage to the tabletop caused by rigid locking.

[0014] Furthermore, the fastener also includes: A fixing pad is provided at the top of the fixing rod and is formed as a rubber part, and the fixing pad is provided with anti-slip patterns; A covering element is disposed on the outer peripheral surface of the fixed sleeve and is fixedly connected to the fixed sleeve. The covering element is formed as a rubber part and its outer peripheral surface is provided with anti-slip patterns.

[0015] Through the above technical solution, this application adds a rubber fixing pad and a covering to the fixing component. The fixing pad is located at the top of the fixing rod, and the covering covers the outer surface of the sleeve. Both surfaces are decorated with anti-slip patterns (such as diamond or wave patterns), significantly reducing the risk of slipping in wet environments. The elastic deformation capability of the rubber material can adapt to minor unevenness of the tabletop while avoiding scratches on expensive tabletops. The covering also provides damping and shock absorption, absorbing the impact energy generated by a baby's movements and reducing noise transmitted to the tabletop. This design achieves a balance between functionality and protection, solving the defects of metal clamping devices that are prone to slipping and damaging the tabletop.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This application discloses a highly stable fixed baby table chair. The design incorporates a vertically adjustable fixing mechanism via threads, springs, or slide rails, ensuring uniform force distribution between the tray and the tabletop contact surface, avoiding stress concentration issues associated with traditional single-point clamping. This design significantly improves stability, especially reducing the risk of lateral displacement during infant movement, while also being compatible with tabletops of different structures, solving the problem of poor adaptability in existing clamping devices. Furthermore, the integrated fixing design of the tray and seat body reduces structural complexity and enhances overall rigidity, providing a safer dining environment for infants.

[0017] 2. This application optimizes the composition of the desktop mounting bracket, including a detachable connecting rod and a U-shaped support rod. The connecting rod is detachably connected to the seat body and tray at both ends, facilitating quick assembly, disassembly, and storage. One end of the U-shaped support rod is fixed to the connecting rod, while the other end connects to a fixing component. Its closed-section design enhances bending stiffness, effectively resisting cyclic loads generated by infant movement. The U-shaped structure also forms a stable triangular mechanical frame, directly transferring the force on the tray to the desktop, reducing the risk of seat body deformation. The modular design balances portability and strength; the detachable support rod can be cleaned or replaced individually without disassembling the entire seat, solving the maintenance inconvenience problem of traditional integrated brackets. This structure is particularly suitable for scenarios requiring frequent handling or storage.

[0018] 3. This application further optimizes the mechanical structure of the fastener. The fixing sleeve is installed at the end of the support rod, and the vertical height of the fixing rod is adjusted by screwing it into the sleeve. The spring fills the thread gap to provide axial cushioning, while the preload automatically compensates for loosening caused by vibration. This design combines the precise locking of the thread with the dynamic cushioning of the spring, ensuring clamping stability while avoiding damage to the tabletop caused by rigid locking.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] like Figure 1-3 A highly stable fixed baby table chair includes a seat body 1, a tray 2 at the front end of the seat body 1, and two tabletop fixing brackets 3 between the tray 2 and the seat body 1. The two tabletop fixing brackets 3 are on the same plane as the baffles on both sides of the seat body 1. Each tabletop fixing bracket 3 has a rod-shaped connecting rod, one end of which is inserted into the baffle on one side of the seat body 1, and the other end is inserted into the end of one side of the tray 2.

[0025] A U-shaped support rod is fixedly connected below the connecting rod. One end of the support rod is vertically fixed to the connecting rod, and the other end of the support rod faces the bottom surface of the tray 2 and is set perpendicular to the tray 2. At the other end of the support rod, a fixing member 31 is fitted. The fixing member 31 has a fixing sleeve 311 with openings at both ends and a receiving cavity in the middle. The inner wall of the fixing sleeve 311 has an internal thread extending in its axial direction. Inside the receiving cavity of the fixing sleeve 311, a fixing rod 312 is threadedly connected. The fixing rod 312 is formed as a metal rod and its outer circumference has an external thread extending in its axial direction. The external thread on the outer circumference of the fixing rod 312 matches the internal thread in the fixing sleeve 311 and there is an axial clearance after the threads are engaged. An elastic element 313, which is a metal spring, is provided in the axial clearance.

[0026] The fixing sleeve 311 is fitted and fixed to the other end of the support rod. A rubber covering is wrapped around the outer circumference of the fixing sleeve 311. A rubber fixing pad 314 is provided at the end of the covering near the tray 2. Anti-slip patterns are provided on the outer surfaces of the fixing pad 314 and the covering.

[0027] The operating steps for the highly stable fixed baby table chair of this application include: (1) Insert one end of the connecting rod of the two symmetrically distributed desktop fixing brackets 3 into the slots of the side panels of the seat body 1, and insert the other end into the slot of the corresponding side of the tray 2, so as to ensure that the connecting rod forms a rigid connection with the side panel and the tray 2, and the U-shaped structure of the support rod hangs down naturally to the bottom of the tray 2, and place the tray 2 on the desktop. (2) The metal fixing rod 312 inside the fixing sleeve 311 at the end of the rotating support rod uses the cooperation between its external thread and the internal thread of the fixing sleeve 311 to make the fixing rod 312 move downward in the vertical direction. The fixing member 31 is loosened so that the fixing member 31 is placed against the bottom of the table under the action of the elastic member 313. When the fixing pad 314 contacts the table, the anti-slip pattern increases the friction coefficient of the contact surface and prevents slippage.

[0028] (3) After adjustment, the threaded engagement of the fixing rod 312 and the spring pressure form a double locking mechanism. When disassembly is required, rotate the fixing rod 312 to retract it into the fixing sleeve 311 and release the clamp on the tabletop. Pull out the plug-in parts at both ends of the connecting rod to separate the bracket from the seat body 1 and the tray 2.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
