Description

Technical Field

[0001] This invention relates to the field of children's furniture technology, and specifically to a children's bed that can be used in conjunction with an adult bed. Background Technology

[0002] Currently, children's modular beds on the market generally suffer from two major technical pain points: First, the height adjustment is not precise enough or has a limited range, making it difficult to achieve complete flush with adult mattresses of various heights, posing a risk of falls or a poor sleeping experience. Second, to address the gaps caused by the protruding edges of adult beds, the industry commonly uses a customized solution of adding an extra "extension board" to one side of the children's bed for reinforcement. This solution is not only structurally weak and easily damaged, but also cannot be standardized for mass production, resulting in high costs and an unsightly appearance. Furthermore, the guardrail connection methods of existing products are mostly simple, inconvenient to adjust, or difficult to disassemble and assemble, making it difficult to ensure stability while meeting the need for flexible adaptation.

[0003] To address the height adjustment issue, existing technologies include solutions using telescopic bed legs (which can be considered the applicant's prior solution A). However, such solutions typically place the load-bearing structure at the top of the telescopic uprights, resulting in a high center of gravity and limited resistance to tilting. More importantly, the safety rails usually need to be directly or indirectly connected to the bed board or a thin support point. When children frequently lean against or move around, the rails are prone to wobbling, posing a safety hazard and failing to fundamentally meet users' highest requirements for rail stability.

[0004] Therefore, there is an urgent need for a children's interlocking bed that can achieve precise and stepless adjustment of height and front-back position, provide extremely stable rigid support for safety railings, and has a standardized structure that is easy to manufacture, while also having a flexible and convenient connection method. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a height- and position-adjustable children's modular bed. This modular bed, through a novel "fixed column suspended sliding frame" structural topology, not only achieves stepless adjustment in two dimensions but also integrates the supporting foundation of the safety rails with the main load-bearing frame of the bed, thereby achieving stability and safety comparable to fixed beds under standardized production conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A height- and position-adjustable children's interlocking bed includes four vertical posts supported on the ground, two load-bearing crossbeams, a bed board, and at least one guardrail unit.

[0007] Its core innovation lies in: The two load-bearing beams are parallel to each other, and each load-bearing beam is connected to the corresponding column at both ends by a sliding locking mechanism. This sliding locking mechanism allows the load-bearing beam to slide up and down along the axis of the column, and can be firmly locked to the column after sliding to any desired height, thus forming a rigid support frame that can be raised and lowered as a whole.

[0008] The bed board is placed or installed on two load-bearing crossbeams and can slide independently back and forth along the width direction of the load-bearing crossbeams (i.e., the width direction of the bed) to precisely match the edge of an adult bed of different thicknesses.

[0009] The upper part of the guardrail unit is detachably and adjustablely connected to at least one post via a first connecting structure, and its lower part is supported on a load-bearing beam or bed board. Preferably, the guardrail unit is an integral frame, the lower part of which can be simply placed on the load-bearing beam or bed board, providing auxiliary support while allowing it to move independently of the bed board to re-fit against the edge of the bed board after the bed board position changes.

[0010] Furthermore, the sliding locking mechanism can be a locking collar sleeved on the post, radially locked by a set screw or bolt; or it can be a sliding clamp clamped on the side of the post, locked by a through bolt. The first connection structure can be a bolted fit between a vertical adjustment elongated hole on the guardrail unit and a positioning hole on the side of the post; or it can be a mounting groove with a sliding nut on the guardrail unit, fitted with a sliding connector with a through hole on the post, fastened by bolts.

[0011] Furthermore, the bottom of the column may be equipped with anti-slip pads or height-adjustable feet to enhance the stability of the bed and its adaptability to different terrains.

[0012] Furthermore, the bed board can be a single board with slide rails, or it can be a combination of multiple independently sliding square tubes to meet different breathability requirements.

[0013] Furthermore, the top of the column can be pre-installed with threaded holes, plug-in interfaces, and other functional interfaces, making it convenient for users to add mosquito net frames, baby monitor brackets, or fun toy racks, thus expanding the product's functionality.

[0014] The beneficial effects of this invention are as follows: Precise and fully adaptable: The sliding locking mechanism enables stepless height adjustment of the bed support surface, and the front and back sliding of the bed board achieves seamless splicing with bed edges of any thickness, completely replacing the unstable "extension board".

[0015] Revolutionary stability: The load-bearing beams are creatively "suspended" from the sides of the fixed columns via rigid connectors, forming a low-center-of-gravity, "U"-shaped closed frame structure with excellent mechanical properties. More importantly, the upper part of the safety railing is directly connected to the columns that serve as the main load-bearing skeleton, resulting in a direct and short force transmission path. This fundamentally eliminates the root cause of railing swaying, leading to a qualitative leap in safety.

[0016] Flexible and convenient adjustment: The height of the bed, the front and back positions of the bed board, and the front and back positions of the guardrails can all be adjusted independently without interference. Users can make the most convenient adjustment combination according to their actual situation.

[0017] Standardization and scalability: The highly modular structure facilitates standardized production, packaging, and transportation. The tall column design naturally creates a platform for functional expansion, enhancing the product's added value.

[0018] Stability and adaptability: The anti-slip or fine-adjustment design at the bottom of the uprights ensures the bed stands stably on various ground conditions and allows for fine-tuning of the initial level, improving the user experience and safety. Attached Figure Description

[0026] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a height- and position-adjustable children's modular bed. This modular bed, through a novel "fixed column suspended sliding frame" structural topology, not only achieves stepless adjustment in two dimensions but also integrates the supporting foundation of the safety rails with the main load-bearing frame of the bed, thereby achieving stability and safety comparable to fixed beds under standardized production conditions.

[0027] To achieve the above objectives, the present invention adopts the following technical solution: A height- and position-adjustable children's modular bed includes four vertical supports on the ground, two load-bearing crossbeams, a bed board, and at least one guardrail unit. Its core innovation lies in: The two load-bearing beams are parallel to each other, and each load-bearing beam is connected to the corresponding column at both ends by a sliding locking mechanism. This sliding locking mechanism allows the load-bearing beam to slide up and down along the axis of the column, and can be firmly locked to the column after sliding to any desired height, thus forming a rigid support frame that can be raised and lowered as a whole.

[0028] The bed board is placed or installed on two load-bearing crossbeams and can slide independently back and forth along the length of the load-bearing crossbeams (i.e., the width of the bed) to precisely match the edge of an adult bed of different thicknesses.

[0029] The upper part of the guardrail unit is detachably and adjustablely connected to at least one post via a first connecting structure, and its lower part is supported on a load-bearing beam or bed board.

[0030] Preferably, the guardrail unit is an integral frame, the lower part of which can be simply placed on the load-bearing beam or bed board, which can provide auxiliary support and allow it to move independently of the bed board to re-fit the edge of the bed board after the position of the bed board changes.

[0031] Furthermore, the sliding locking mechanism can be a locking collar sleeved on the post, radially locked by a set screw or bolt; or it can be a sliding clamp clamped on the side of the post, locked by a through bolt. The first connection structure can be a bolted engagement between a vertical adjustment elongated hole on the guardrail unit and a positioning hole on the side of the post, or it can be a sliding clamp, or it can be a mounting groove with a sliding nut on the guardrail unit, fastened with bolts to a sliding connector with a through hole sleeved on the post.

[0032] Furthermore, the bottom of the column may be equipped with anti-slip pads or height-adjustable feet to enhance the stability of the bed and its adaptability to different terrains.

[0033] Furthermore, the bed board can be a single board with slide rails, or it can be a combination of multiple independently sliding square tubes to meet different breathability requirements.

[0034] Furthermore, the top of the column can be pre-installed with threaded holes, plug-in interfaces, and other functional interfaces, making it convenient for users to add mosquito net frames, baby monitor brackets, or fun toy racks, thus expanding the product's functionality.

[0035] The beneficial effects of this invention are as follows: Precise and fully adaptable: The sliding locking mechanism enables stepless height adjustment of the bed support surface, and the front and back sliding of the bed board achieves seamless splicing with bed edges of any thickness, completely replacing the unstable "extension board".

[0036] Revolutionary stability: The load-bearing beams are creatively "suspended" from the sides of the fixed columns via rigid connectors, forming a low-center-of-gravity, "U"-shaped closed frame structure with excellent mechanical properties.

[0037] Flexible and convenient adjustment: The height of the bed, the front and back positions of the bed board, and the front and back positions of the guardrails can all be adjusted independently without interference. Users can make the most convenient adjustment combination according to their actual situation.

[0038] The connection methods are diverse and reliable: it provides a variety of guardrail connection methods such as vertical elongated hole positioning, clamp locking, and sliding nut collar locking, all of which can achieve fast and stable stepless or differential adjustment, greatly improving the convenience of installation, adaptation and disassembly.

[0039] Standardization and scalability: The highly modular structure facilitates standardized production, packaging, and transportation. The tall column design naturally creates a platform for functional expansion, enhancing the product's added value.

First connecting structure; 511. Vertical adjustment elongated hole; 512. Mounting groove; 513. Sliding nut; 514. Collar connector; 515. Connecting bolt; 6. Adult bed. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0048] like Figures 1 to 3 As shown, the height- and position-adjustable children's modular bed provided by this invention consists of four upright columns 1 supported by the ground, two load-bearing crossbeams 2, a bed board 4, and a guardrail unit 5. The bottom of each column 1 is preferably equipped with anti-slip pads or height-adjustable feet (not shown in the figure). Under the weight of the bed frame, bed board, and user, the four columns 1 can stand stably on the ground without the need for drilling holes for fixing. The entire bed can be moved or transported as a complete piece of furniture.

[0049] like Figure 2 and Figure 3 As shown, the column 1 is a metal tube with a circular cross-section. The load-bearing beam 2 is a square tube, with a locking collar 31, which serves as a sliding locking mechanism 3, fixedly connected to each end. The locking collar 31 is fitted onto the column 1 and can slide freely up and down along the column 1. The side wall of the locking collar 31 has threaded holes. By screwing in the fastening bolts 32, the inner wall of the collar can be tightly locked to the column 1, thereby fixing the load-bearing beam 2 in its current position. By simultaneously adjusting and locking the height of the four locking collars 31, the height adjustment of the entire bed support surface can be completed. In another embodiment, the sliding locking mechanism 3 can also be a sliding clamp (not shown in the figure) that holds the side of the column 1.

[0050] like Figure 1 and Figure 6As shown, the bed board 4 is composed of multiple parallel wooden or plastic square tubes 41 arranged side by side. Each square tube 41 has its two ends directly supported on the upper surfaces of two load-bearing crossbeams 2. Since the square tubes 41 are not fixed to the load-bearing crossbeams 2, each square tube 41 can independently slide back and forth along the width direction of the load-bearing crossbeam 2 (in the direction indicated by the arrow). When it is necessary to fit against the edge of the adult bed 6, simply push all the square tubes 41 forward until they are flush with the edge. Limiting blocks (not shown in the figure) can also be installed on the load-bearing crossbeams 2 to prevent the square tubes 41 from slipping off. In another embodiment, the bed board 4 can also be a single solid board with a plastic slider installed at its bottom to allow sliding on the load-bearing crossbeams 2.

[0051] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the guardrail unit 5 is assembled from three independent guardrails located on the head side, tail side and outer side of the bed through corner connectors.

[0052] As one embodiment of the first connection structure 51, such as Figure 4 As shown, a connecting plate with a vertical adjustment hole 511 can be installed on the corner vertical bar facing the inside of the bed in the guardrail unit 5. During installation, the connecting plate is attached to the side of the column 1, and bolts are passed through the long hole 511 and screwed into the preset positioning hole (not shown in the figure) on the side of the column 1 for fixation.

[0053] As another preferred implementation, such as Figure 5 As shown, the first connecting structure 51 includes: a mounting groove 512 on the upper crossbar of the head / tail side of the guardrail unit 5, with a slidable nut 513 inside the groove 512; and a collar connector 514 sleeved on the post 1 and capable of sliding up and down and locking, the connector 514 having a through hole. During installation, the lower part of the guardrail unit 5 is placed on the load-bearing crossbeam 2 or the bed board 4, the collar connector 514 is slid so that its through hole aligns with the sliding nut 513, and then a connecting bolt 515 is screwed into the nut 513 through the through hole and tightened to complete the fixing. This method allows for stepless fine-tuning of the guardrail unit 5 in the front-back and up-down directions.

[0054] In another embodiment, the first connecting structure 51 may also employ a clamp (not shown in the figure) that can be slidably held on the side of the column 1.

[0055] Regardless of the connection method used, the lower part of the guardrail unit 5 is supported on the load-bearing crossbeam 2 or the bed board 4.

[0056] Its adjustment and usage process is as follows: Height adjustment: Loosen the four fastening bolts 32, raise and lower the two load-bearing crossbeams 2 (along with the bed board 4 above them) to the same height as the mattress of the adult bed 6, and then tighten the fastening bolts 32. If using... Figure 4 If the connection method is as described above, then the height of the collar connector 514 should be adjusted synchronously and locked.

[0057] Forward and backward position adjustment (bed edge adaptation): If the bed edge of the adult bed 6 is thick, push all the square tubes 41 (or the entire bed board 4) forward until there is no gap. At this time, a gap may appear between the guardrail unit 5 and the bed board 4.

[0058] Repositioning the guardrail: Loosen the connector (connecting bolt 515 or other fasteners) at the top of guardrail unit 5, push the entire guardrail unit 5 forward along the load-bearing beam 2 until it is flush with the edge of the bed board 4, and then tighten it again. For Figure 4 In this manner, the sliding nut 513 can move within the groove 512 to accommodate this adjustment.

[0059] In addition, threaded blind holes or slots can be machined at the top of the column 1 for installing accessories such as mosquito net frames and monitors, thereby expanding its functionality.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Those skilled in the art can make various modifications and equivalent substitutions without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
