Description

Technical Field

[0001] This utility model belongs to the field of children's beds, specifically relating to an adjustable multifunctional children's bed. Background Technology

[0002] With the improvement of living standards and changes in concepts and awareness, baby products are receiving more and more attention from parents, such as cribs.

[0003] Most children's beds on the market currently use fixed guardrails, whose main function is to prevent children from falling off the side of the bed during sleep or activity, thus ensuring basic safety. However, this rigid, fixed guardrail has significant limitations in actual use. For example, during daily care of infants and toddlers, caregivers frequently need to pick them up, put them down, change diapers, assist with toileting, or engage in parent-child reading. In these situations, the fixed guardrail often becomes a physical obstacle, forcing caregivers to bend over and climb over the guardrail, walk around the foot of the bed, or even temporarily disassemble some guardrail components. Such operations are not only time-consuming and laborious, reducing care efficiency, but may also cause caregivers to fall due to instability, or cause secondary safety hazards such as loosening or falling off of the guardrail due to improper operation during disassembly and assembly. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an adjustable, multifunctional children's bed that is simple in structure, has good stability, and is convenient for children to pass through or for caregivers to operate.

[0006] The lifting barrier is slidably installed in the front guardrail along the vertical direction and can be switched between the open and closed positions on the front guardrail.

[0007] An unlocking component is provided inside the lifting bar. The unlocking component includes an unlocking block and a locking pin. When the unlocking block moves, it can drive the locking pin to disengage from the front guardrail and retract into the lifting bar, so that the lifting bar can switch between the open position and the closed position.

[0008] When the lifting barrier is in the closed position, the locking pin is inserted into the front guardrail, so that the top wall of the lifting barrier is flush with the top wall of the front guardrail.

[0009] The lifting platform can be switched from the closed position to the open position after the locking pin is unlocked, so that the top wall of the lifting platform remains flush with the supporting platform.

[0010] In the aforementioned adjustable multifunctional children's bed, the unlocking assembly further includes a drive block and a traction rope. The drive block is distributed on both sides of the unlocking block and moves against it. One end of the traction rope is connected to the drive block, and the other end is connected to the locking pin.

[0011] In the aforementioned adjustable multifunctional children's bed, the support platform is detachably connected to a support frame arranged in a stepped manner. The support frame has through holes, and the front guardrail and the rear guardrail each have several adjustment holes in the vertical direction. The through holes can be connected to any one of the adjustment holes.

[0012] In the aforementioned adjustable multifunctional children's bed, the support platform is detachably connected to a support frame arranged in a stepped manner. The support frame has through holes, and the front guardrail and the rear guardrail each have several adjustment holes in the vertical direction. The through holes can be connected to any one of the adjustment holes.

[0013] In the aforementioned adjustable multifunctional children's bed, the unlocking component further includes an elastic element, an extension block is formed on the inner wall of the unlocking block, the extension block is provided with a connecting block, the bottom end of the elastic element is connected to the connecting block, and the top end movably abuts against the inner wall of the lifting rail.

[0014] In the aforementioned adjustable multifunctional children's bed, the lifting rail is further provided with a limiting block and a cover plate. The end of the driving block away from the traction rope moves against the limiting block. A limiting groove is formed on the cover plate. An extension handle is formed on the unlocking block. The extension handle extends out of the cover plate and is movably disposed in the limiting groove.

[0015] In the aforementioned adjustable multifunctional children's bed, the side wall of the lifting rail is formed with a guide block, the side wall of the front guardrail is formed with a guide groove, and the guide block is movably engaged in the guide groove.

[0016] In the aforementioned adjustable multifunctional children's bed, a plurality of locking holes are formed in the guide groove, and the locking pin is movably inserted into the locking holes to restrict the lifting rail to the closed position or the open position.

[0017] In the aforementioned adjustable multifunctional children's bed, the support platform includes a main platform and side platforms distributed on both sides thereon. The bottom of the side platforms is connected to a support block, and the main platform is connected to the support block and is flush with the surface of the side platforms.

[0018] In the aforementioned adjustable multifunctional children's bed, a replaceable guardrail is detachably connected inside the rear guardrail.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0035] like Figures 1 to 7 As shown, this utility model discloses an adjustable multifunctional children's bed, which includes: a front guardrail 10, a rear guardrail 11, two sets of side rails 12, a support platform 13, a lifting rail 2, and an unlocking component 3.

[0036] In this embodiment, the front guardrail 10, rear guardrail 11, two sets of side rails 12, and support platform 13 together form a receiving chamber 140. The lifting rail 2 is slidably disposed within the front guardrail 10 in a vertical direction and can switch between an open position and a closed position on the front guardrail 10. The unlocking component 3 is disposed within the lifting rail 2 and includes an unlocking block 30 and a locking pin 31. When the unlocking block 30 moves, it can drive the locking pin 31 to disengage from the front guardrail 10 and retract into the lifting rail 2, so that the lifting rail 2 can switch between an open position and a closed position. When the lifting rail 2 is in the closed position, the locking pin 31 is inserted into the front guardrail 10, so that the top wall of the lifting rail 2 is flush with the top wall of the front guardrail 10. The lifting rail 2 can switch from the closed position to the open position after the locking pin 31 is unlocked, so that the top wall of the lifting rail 2 is flush with the support platform 13.

[0037] like Figure 1As shown, in normal use, the lifting rail 2 is locked in the closed position by the locking pin 31. At this time, the lifting rail 2 can form a continuous and complete protective boundary with the front guardrail 10, effectively preventing children on the support platform 13 from falling off, ensuring sleep safety, and also improving the overall aesthetics. When the caregiver needs to pick up or put down the child, assist with toileting, or engage in bedside interaction, they only need to push the unlocking block 30 upwards with one hand. Figure 2 Vertical movement is converted into locking pin 31 along Figure 2 The horizontal displacement causes the locking pin 31 to disengage from the front guardrail 10, allowing the lifting barrier 2 to move freely after losing its limit constraint. Figure 1 The lifting rail 2 slides freely vertically. As it smoothly slides down the inside of the front guardrail 10 to the open position, the top wall of the lifting rail 2 is flush with the surface of the support platform 13. The locking pin 31 then re-inserts into the front guardrail 10 to complete the locking function, allowing adults to begin caregiving. It is worth noting that when the outside of the children's bed is close to the adult bed frame, the flushing of the lifting rail 2 with the support platform 13 means that the support platform 13 is flush with the external bed frame, thus forming a continuous plane. This ensures that children can easily climb from the children's bed into the adult bed. Therefore, this embodiment utilizes the lifting rail 2 in conjunction with the unlocking component 3 to switch between the closed position (flush with the top wall of the front guardrail 10) and the open position (flush with the support platform 13), effectively solving the problem of traditional children's bed guardrails being fixed and unadjustable. Simultaneously, the unobstructed passage created in the open position facilitates the child's movement between the adult bed and the children's bed, or the caregiver's operation, significantly improving safety and convenience.

[0038] The unlocking component 3 also includes a drive block 32 and a traction rope. The drive block 32 is distributed on both sides of the unlocking block 30 and moves against it. One end of the traction rope is connected to the drive block 32 and the other end is connected to the locking pin 31.

[0039] like Figure 2 As shown, when the user moves the unlock block 30 along... Figure 2 When moving vertically upwards, the drive blocks 32 on both sides are pulled closer together. During this process, the traction rope (not shown in the figure) transmits the pulling force of the drive blocks 32 to the locking pins 31. As the locking pins 31 overcome the spring force of the return springs (each locking pin 31 is connected to a return spring, not shown in the figure), the locking pins 31 move along... Figure 2The horizontal movement disengages from the front guardrail 10 and retracts into the lifting barrier 2. It is worth noting that, due to the presence of drive blocks 32 and traction ropes on both sides, the locking pins 31 on both sides retract synchronously and evenly through balanced traction of the double ropes, preventing jamming or uneven loading. Because of this, the user only needs to operate the unlocking block 30 to synchronously retract the locking pins 31 on both sides via the traction ropes, achieving rapid unlocking and position switching of the lifting barrier 2. This structure simplifies the operation steps, improves the stability and reliability of operation, avoids the tedious process of manually unlocking one by one, and further enhances the ease of use and user experience of the product.

[0040] An unlocking push block 300 with an unlocking slope 300a is formed on the unlocking block 30, and a fixing block 320 with a driving slope 320a is formed on the driving block 32. The unlocking push block 300 moves against the fixing block 320, so that the unlocking slope 300a moves tightly against the driving slope 320a.

[0041] like Figure 2 , Figure 5 as well as Figure 6 As shown, in this embodiment, the unlocking block 30 is moved along the inclined plane transmission. Figure 2 or Figure 5 The vertical linear motion is efficiently converted into the lateral displacement of the drive block 32, which in turn pulls the traction rope to complete the unlocking function of the locking pin 31. The sliding contact between the inclined surfaces avoids rigid collisions or sudden jumps, making the unlocking process quiet, smooth, and without any jerking sensation, reducing the operating force required for unlocking and improving the user experience. At the same time, the symmetrical inclined surfaces on the left and right ensure the stable and synchronous movement of the drive blocks 32 on both sides, effectively preventing the lifting barrier 2 from tilting or jamming due to uneven force, and improving the stability of long-term use.

[0042] The unlocking component 3 also includes an elastic element 33. An extension block 301 is formed on the inner wall of the unlocking block 30. The extension block 301 is provided with a connecting block 301a. The bottom end of the elastic element 33 is connected to the connecting block 301a, and the top end moves against the inner wall of the lifting bar 2.

[0043] like Figure 5 As shown, along the unlocking block 30 Figure 5When the lifting bar 2 is raised vertically, the unlocking block 30 and the driving block 32 achieve force conversion through the two inclined surfaces. Simultaneously, the elastic element 33 experiences compression and contraction due to the movement of the extension block 301. When the lifting bar 2 is adjusted to the desired position, as the user releases the unlocking force on the unlocking block 30, the elastic element 33's elastic reset function allows the unlocking block 30 to automatically and accurately return to its original position after the user releases the operation. This, in turn, causes the locking pin 31 to re-insert into the front guardrail 10, achieving automatic locking of the lifting bar 2. This design improves safety and reliability, preventing the lifting bar 2 from accidentally slipping due to misoperation or forgetting to lock, while also enhancing the self-locking reliability of the mechanism. It should be noted that the elastic element 33 in this embodiment can be a compression spring or a return spring, etc.

[0044] The lifting platform 2 is also provided with a limit block 20 and a cover plate 21. The end of the drive block 32 away from the traction rope moves against the limit block 20. A limit groove 210 is formed on the cover plate 21. An extension handle 302 is formed on the unlocking block 30. The extension handle 302 extends to the outside of the cover plate 21 and is movably disposed in the limit groove 210.

[0045] like Figure 3 , Figure 5 as well as Figure 6 As shown, in this embodiment, a vertical guide groove 23 and a horizontal guide groove 24 are formed inside the lifting rail 2. The extension block 301 on the unlocking block 30 moves within the vertical guide groove 23, while the drive blocks 32 on both sides move within the horizontal guide groove 24. This ensures that the user's vertical lifting force is converted into a lateral component force of the drive block 32 using the two inclined surfaces. In addition, the limit stop 20 precisely limits the movement stroke of the drive block 32, preventing excessive displacement that could lead to mechanism failure. Furthermore, in this embodiment, the limit groove 210 on the cover plate 21 cooperates with the extension handle 302 of the unlocking block 30, protecting the internal structure from dust intrusion and guiding the handle to slide along a predetermined trajectory, ensuring precise operation. The overall structure is compact and has good protection, improving the product's aesthetics, safety, and service life.

[0046] The side wall of the lifting barrier 2 has a guide block 22, and the side wall of the front guardrail 10 has a guide groove 100. The guide block 22 is movably engaged in the guide groove 100.

[0047] like Figure 2 and Figure 4 As shown, in this embodiment, the lifting railing 2 and the front guardrail 10 are connected by the cooperation of the guide block 22 and the guide groove 100. After the locking pin 31 unlocks the lifting railing 2, the vertical lifting of the lifting railing 2 is stably guided by the guide block 22 and the guide groove 100, which effectively prevents it from tilting, jamming or shaking during the movement, ensuring that the lifting process is smooth and stable, and improving the safety and structural stability.

[0048] Several locking holes 100a are also formed in the guide groove 100. The locking pin 31 is movably inserted into the locking hole 100a to restrict the lifting rail 2 to the closed position or the open position.

[0049] like Figure 2 As shown, in this embodiment, multiple locking holes 100a are provided in the guide groove 100, so that the locking pin 31 can be selectively inserted into different locking holes 100a, thereby reliably locking the lifting railing 2 in the closed position or the open position (the open position can be adaptively adjusted according to the position of the support platform 13). This multi-position locking mechanism enhances the reliability of the fixed position, prevents the lifting railing 2 from moving accidentally during use, and supports stable locking in both states, taking into account both safety protection and convenient passage.

[0050] The support platform 13 is detachably connected to a support frame 130 arranged in a stepped manner. The support frame 130 has a through hole 130a. The front guardrail 10 and the rear guardrail 11 both have several adjustment holes 141 in the vertical direction. The through hole 130a can be connected to any one of the adjustment holes 141.

[0051] like Figure 1 and Figure 7 As shown, in a traditional children's bed, the support platform 13 is the entire bed base. In this embodiment, to adapt to the height of an adult bed, the support platform 13 is movably installed inside the children's bed. Specifically, the support platform 13 can be connected to the stepped support frame 130 by screws or bolts, and cooperates with multiple adjustment holes 141 on the front and rear guardrails 11 through through holes 130a, so that the height of the support frame 130 can be flexibly adjusted according to the child's age, height, or usage needs. This design not only expands the applicable age range of the children's bed, but also improves space utilization efficiency, and is easy to disassemble, transport, and store, with good modularity and adaptability.

[0052] The support platform 13 includes a main platform 131 and side platforms 132 distributed on both sides thereon. The bottom of the side platform 132 is connected to a bearing block 133. The main platform 131 is connected to the bearing block 133 and is flush with the surface of the side platform 132.

[0053] like Figure 7 As shown, the support platform 13 in this embodiment adopts a structure combining a main platform 131 and two side platforms 132, and is flush-connected by a bearing block 133. This structure not only expands the sleeping or activity area, but also enhances the overall rigidity and load-bearing capacity of the platform. Furthermore, this modular design facilitates transportation, assembly, and subsequent maintenance, and allows for individual component replacement as needed, reducing operating costs. Preferably, the support platform 13 in this embodiment can be horizontal or tilted (to prevent choking on milk).

[0054] In a further preferred embodiment, a replacement guardrail 110 is detachably connected to the rear guardrail 11 by screws or bolts. In different seasons, usage scenarios, or stages of a child's growth, the user can simultaneously disassemble the replacement guardrail 110, the main platform 131, the lifting rail 2, and the base plate of the children's bed (which has the same structure as the support platform 13, and the main platform 131 in the base plate can be removed). According to actual usage needs, different specifications (increasing the length to expand the volume of the accommodating chamber 140) or patterns of the product can be selected for replacement, which greatly enhances the personalization and functionality of the children's bed, extends the product life cycle, and meets diverse childcare needs.
