Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid wood furniture technology, specifically to a solid wood high chair with an adjustable height footrest. Background Technology
[0002] Most existing solid wood high chairs are fixed structures and cannot be flexibly adjusted according to the user's height or usage scenario. Especially in scenarios with different heights such as bar counters, high dining tables, and kitchen operations, using a fixed-height footrest will cause the feet to dangle, affecting comfort and safety.
[0003] Furthermore, in some homes or venues with limited space, traditional high chairs lack folding or storage functions, occupying space for extended periods and reducing their ease of use. In practical applications, the demand for height-adjustable and foldable structures is becoming increasingly significant.
[0004] Therefore, a solid wood high chair that combines adjustable footrest height with folding and storage functionality can solve the problems of simple structure, poor adaptability, and inconvenient storage in existing technologies. Utility Model Content
[0005] To overcome the problems of existing solid wood high chairs having non-adjustable structures and being inconvenient to store, this utility model provides a solid wood high chair with an adjustable height footrest platform.
[0006] The technical solution of this utility model is: a solid wood high chair with an adjustable height footrest, including a chair body, chair legs and a footrest. The footrest is connected to the chair legs through a multi-segment slide rail structure set on the chair legs, and is provided with a slot-type locking mechanism for adjusting and fixing the height; the chair body is also provided with a folding connector to realize overall folding.
[0007] The beneficial effects of this utility model are as follows: by combining the multi-segment slide rail structure with the slot-type locking mechanism, the height of the footrest platform can be flexibly adjusted to accommodate users of different heights; the folding connector makes the chair easy to store and move, improving ease of use.

[0010] Example 1: As Figure 1 and Figure 2As shown, a solid wood high chair with an adjustable footrest includes a chair body 1, chair legs 2, and a footrest 3. The footrest 3 is connected to the chair legs 2 via a multi-segment slide rail structure 4 mounted on the chair legs 2. The slide rail structure 4 is an embedded metal guide rail system, consisting of three nested guide rails. The outer guide rail is fixed to the inside of the chair legs 2, the middle guide rail slides in conjunction with the outer guide rail, and the inner guide rail is fixedly connected to the footrest 3. The guide rails slide smoothly and are segmented for positioning via limiting protrusions and sliding grooves. During adjustment, the user can pull the footrest 3 up and down along the guide rails until the corresponding slot locks in place, achieving height adjustment and stable fixation. The slot-type locking mechanism 5 includes several positioning slots 51 mounted on the slide rail structure 4 and elastic latches 52 fixed to the footrest 3. The elastic latch 52 is preferably made of spring steel sheet or nylon sheet, with a thickness of 0.5mm to 1.5mm and a length of 20mm to 40mm, to ensure sufficient elasticity and rebound force during repeated use. One end of the latch 52 is fixed to the bottom of the foot platform 3 by rivets or screws, and the other end is a free end that extends outward along the slide rail direction. Positioning positions 51 are arranged at intervals along the length of the slide rail structure 4, with a spacing of 20mm to 30mm and a positioning depth of approximately 1mm to 2mm, adapted to the free end of the latch. When the user lifts or presses down on the foot platform 3, the free end of the latch crosses the edge of the positioning position under the action of external force and rebounds and embeds itself after the external force is released, achieving reliable locking; when unlocking, the user presses the free end of the latch inward to disengage it from the positioning position, then moves the foot platform to the target position and releases the user, and the latch can re-engage into the new positioning position to complete the height adjustment. In use, the user can directly lift or press down on the foot platform 3 manually without the need for any auxiliary tools. The elastic latch 52 slides along the guide rail surface under external force and automatically springs back into place under its own elasticity after passing the locking position 51, achieving instant locking. To improve safety, the foot platform 3 cannot slide or fall off on its own when not pressed to unlock, ensuring stability during adjustment and use. To unlock, the user simply presses the free end of the elastic latch 52 inward with a finger to disengage it from the locking position 51, then moves the foot platform 3 to the target position and releases the finger, allowing the latch to re-engage in the new locking position, achieving reliable height adjustment and locking. This structure provides multi-level adjustment and is suitable for children and adults. To ensure long-term reliability, the elastic latch 52 is preferably made of spring steel or high-strength nylon material, which has good elastic recovery performance. Repeated pressing fatigue tests have verified that the elastic latch can maintain effective rebound force and locking function after no less than 20,000 cycles, avoiding loosening or failure due to material fatigue, thus ensuring long-term safety and stability. Figure 2a As shown, the free end of the elastic latch 52 is embedded in the positioning slot 51, forming a stable locking state; as Figure 2bAs shown, when the user presses the free end of the elastic latch 52 inward, the latch disengages from the positioning slot 51, and the foot platform 3 can continue to move along the slide rail structure 4, thereby achieving unlocking and height adjustment.
[0011] Example 2: Figure 1 and Figure 3 As shown, the chair body 1 and chair legs 2 are connected by a folding connector 6, which includes a pivot connection structure and a limiting stop. The pivot is preferably a metal pin, located on the inner side of the connection between the chair legs 2 and the chair body 1, used to allow the chair body to rotate relative to the chair legs. The limiting stop is arranged adjacent to the pivot, with its end contacting the inner wall of the chair legs 2. It acts as a limit when the chair body is unfolded, restricting the folding angle to within the range of 90° to 120°, ensuring the stability of the chair body in use. In use, the user can fold the backrest inward along the pivot direction, bringing the chair body and chair legs together. The folding is smoothly completed under the guidance of the limiting stop. When needed, the backrest is rotated outward until the limiting stop engages, restoring the chair to its unfolded state. This structure is particularly suitable for compact spaces such as kitchens and balconies. Figure 4 As shown, when the folding connector 6 is in the folded state, the backrest 8 and the chair legs 2 are folded together, significantly reducing the overall space occupied; as Figure 5 As shown, the folding connector 6 rotates along the pivot during the folding process, and the limiting baffle gradually contacts the inner wall of the chair leg 2 and limits the folding angle, so that the folding process is controlled and excessive rotation or structural damage is prevented.
[0012] Example 3: Further optimization, the footrest platform 3 is a solid wood structure with an anti-slip textured layer 7 on its surface. This textured layer is preferably made of rubber or PVC material and is fixed to the upper surface of the footrest platform 3 by hot pressing or embedding. The textured layer has regular, parallel striped grooves, with a groove width of 1mm, a spacing of 3mm, and a depth of 0.5mm to 1mm, evenly distributed along the width direction of the footrest platform. This structure can form frictional engagement when the foot is under pressure, significantly improving the anti-slip effect, preventing foot slippage, and thus improving safety and comfort during use. Figure 3a As shown, the anti-slip textured layer 7 has a parallel striped groove structure, with a groove width of approximately 1 mm, a spacing of approximately 3 mm, and a depth of approximately 0.5 mm to 1 mm, evenly distributed along the width direction of the footrest platform 3. This structure creates frictional engagement when the user's foot contacts it, effectively preventing slippage and improving safety and comfort.
[0013] Example 4: Figure 1As shown, the chair body 1 includes a backrest 8 and a seat 9, with the backrest 8 and chair legs 2 fixed together by a connecting rod. The connecting rod is preferably a straight or slightly curved metal rod with external threaded sections at both ends, which can engage with the internal threads of corresponding positioning holes on the chair legs 2 and backrest 8. To improve assembly stability, the end of the connecting rod may also have a limiting shoulder to prevent over-screwing. During installation, the user screws the connecting rod into the positioning holes of the backrest 8 and chair legs 2 until the limiting shoulder is in contact with the seat to complete the fixation; during disassembly, the connecting rod is unscrewed in the opposite direction to separate the components, facilitating the transportation, storage, or replacement of components of the high chair. Alternatively, the connecting rod can use a plug-in snap-fit structure, allowing for quick assembly and disassembly through the engagement of the snap-fit pin with the positioning hole.
[0014] Example 5: The bottom of the chair leg 2 is provided with an anti-slip pad 10. The anti-slip pad is made of soft silicone or TPR material, which effectively prevents the high chair from sliding on smooth ground, increases overall stability and safety of use, and is suitable for various ground environments such as ceramic tiles and wooden floors.
[0015] The above description is only a preferred embodiment of this utility model. Those skilled in the art can adjust or replace the structure without departing from the design concept and technical solution of this utility model, and such adjustments or replacements should still be within the protection scope of this utility model.
