Description

Technical Field

[0001] This utility model relates to the field of children's furniture technology, and in particular to a safe and height-adjustable crib. Background Technology

[0002] Currently, some cribs have adjustable guardrails. The common way to adjust the guardrails is as follows: When raising the crib, you need to push the lower end of the guardrail inward first, and then lift the guardrail. After lifting it to the high position, the guardrail can automatically return to its original position and be supported by the limit switch. When lowering the crib, you need to lift the guardrail slightly first to release it from the limit switch, and then push the lower end of the guardrail inward. Then you can gradually release the guardrail to the low position. After the guardrail descends to the low position, it can automatically return to its original position.

[0003] With the aforementioned adjustable guardrail design, it is difficult for a crib to effectively balance safety and smooth guardrail adjustment. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a safe and height-adjustable crib that can effectively balance safety and smooth lifting of the guardrail.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A safe and height-adjustable crib includes a bed frame, a bed board, and a height-adjustable guardrail. The bed frame is equipped with guide rails, and the height-adjustable guardrail is equipped with sliders. There is a space for movement between the sliders and the guide rails in the inward and outward directions of the bed frame. A limiting support bar is provided on the lower part of the guide rail near the inside of the bed frame. When the lower end of the height-adjustable guardrail moves into the bed frame, it is freed from the limiting effect of the limiting support bar and can rise and fall freely. A safety strip is provided on the upper part of the side of the bed board facing the height-adjustable guardrail. The safety strip has the same length as the side of the bed board facing the height-adjustable guardrail, and a clearance space is formed below the safety strip for the guardrail to rise and fall.

[0007] Preferably, the safety strip has a height dimension of 10-14 mm.

[0008] Preferably, the safety strip has a dimension of 5-7 mm along the width of the bed board.

[0009] Preferably, the safety strip is integrally formed with the bed board.

[0010] Preferably, the safety strip is installed and connected to the bed board.

[0011] Preferably, the safety strip is connected to the bed board by nail guns.

[0012] Preferably, the lower end of the safety strip is provided with a chamfer for avoidance.

[0013] Preferably, safety strips are provided on both opposite sides of the bed board.

[0014] Preferably, the bed board has connecting parts at both opposite ends along its length, and the bed frame has at least two sets of connecting holes distributed along its height, with the connecting parts and connecting holes connected by bolts.

[0015] Preferably, the limiting support bar has limiting grooves at both the upper and lower ends.

[0016] The advantages of this utility model are:

[0017] 1. By installing a safety strip on the upper side of the bed board, a small gap between the bed board and the guardrail is ensured, effectively ensuring the safety of the crib and meeting the requirements of safety regulations; while the guardrail lifting clearance space formed below the safety strip on the side of the bed board ensures that the lower end of the guardrail will not interfere with the bed board when it is pushed inward and raised or lowered, ensuring the smoothness of the guardrail lifting and lowering.

[0018] 2. The design of the guardrail for height adjustment and clearance allows the guardrail to be raised and lowered normally when the bed board is at different heights, especially when the bed board is in a low position, thus meeting the needs of this type of crib for bed board height adjustment function;

[0019] 3. The chamfer at the bottom of the safety bar further improves the bed board's ability to avoid obstacles during the raising and lowering of the guardrail, ensuring smooth raising and lowering of the guardrail. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] As mentioned in the background section, existing cribs with adjustable guardrails require the lower end of the guardrail to be pushed inwards when raising or lowering it, and the process is also at an angle. This can easily cause interference with the side of the bed board, affecting the normal raising and lowering of the guardrail. Therefore, these cribs often increase the gap between the bed board and the guardrail to avoid interference during raising and lowering. However, this also results in a larger gap between the bed board and the guardrail, which can easily create safety hazards such as fingers getting trapped, compromising the safety of the crib and making it difficult to pass safety regulations testing.

[0029] Therefore, such as Figure 1 As shown in the illustration, this specification provides a safe and height-adjustable crib, including a bed frame, a bed board 2, and a height-adjustable guardrail 3. The bed frame includes two supporting guardrails 11 and one fixed guardrail 12. The two supporting guardrails 11 are arranged opposite each other and have supporting legs 111 at their lower ends, with casters mounted on the supporting legs. The fixed guardrail 12 is connected between the first side ends of the two supporting guardrails 11, while the height-adjustable guardrail 3 is located between the second side ends of the two supporting guardrails 11. The bed board 2 is bolted to the bed frame.

[0030] As a common type of lifting guardrail structure: guide rails are provided on the opposite sides of the two supporting guardrails 11. Specifically, the guide rails include a split upper guide rail 112 and a lower guide rail 113. A slider is provided on the side of the lifting guardrail 3. The slider also includes an upper slider 31 and a lower slider 32 that respectively cooperate with the upper guide rail 112 and the lower guide rail 113. There is a space for movement between the slider and the guide rails in the direction inward and outward of the bed frame; that is, the lifting guardrail 3 has a certain space to move inward and outward of the bed frame. Figure 2 As shown, a limiting support bar 114 is provided on the side of the lower guide rail 113 near the bed frame. Limiting grooves are provided at both the upper and lower ends of the limiting support bar 114 and the lower guide rail 113, namely the upper limiting groove 115 and the lower limiting groove 116. Of course, each guide rail has a limiting structure at both the upper and lower ends to prevent the slider from sliding out.

[0031] Thus, when the lifting guardrail 3 is in the low position, the lower slider 32 is limited below the limiting support bar 114 and cannot be lifted vertically. Furthermore, due to the presence of the lower limiting groove 116, vertical lifting would cause the lower slider 32 to get stuck in the lower limiting groove 116, making it impossible to lift by brute force. It is necessary to first push the lower end of the lifting guardrail 3 into the bed frame, causing the upper end of the lower slider 32 to disengage from the limiting support bar 114. Then, the lifting guardrail 3 can be lifted. During the lifting process, the lower slider 32 slides upward along the side of the limiting support bar 114 until it exceeds the upper end of the limiting support bar 114. The lower end of the lifting guardrail 3 will then return to its original position under its own weight, causing the lower slider 32 to move above the limiting support bar 114. After releasing, the lifting guardrail 3 automatically falls slightly back, and the lower slider 32 gets stuck in the upper limiting groove 115, completing the stable limiting of the lifting guardrail 3 in the high position.

[0032] To lower the lifting guardrail 3 from a high position to a low position, first slightly lift the lifting guardrail 3 so that the lower slider 32 extends out of the upper limit groove 115. Then push the lower end of the lifting guardrail 3 inward so that the lower slider 32 disengages from the upper limit block of the limit support bar 114. Then, gradually release the lifting guardrail 3 downward. During the process, the lower slider 32 slides down along the side of the limit support bar 114 until it exceeds the lower end of the limit support bar 114. The lower end of the lifting guardrail 3 will then return to its original position under its own weight. After releasing, the lowering adjustment of the lifting guardrail 3 is completed.

[0033] To complement the aforementioned simple and efficient guardrail lifting structure, such as Figure 3 and 4 As shown, this embodiment provides a bed board 2, which mainly consists of two side beams 21 along the length direction and several support plates 22 installed between the two side beams 21. The opposite sides of the two side beams 21 face the lifting guardrail 3 and the fixed guardrail 12, respectively. A safety strip 23 is provided at the upper end of the side beam 21 facing the lifting guardrail 3. The safety strip 23 is the same length as the side beam 21, and a lifting clearance space 24 is formed below the safety strip 23. In this way, the gap between the safety strip 23 and the lifting guardrail 3 meets safety regulations, ensuring safety during use. When the lifting guardrail 3 is raised or lowered, only its lower end moves inward, and the entire lifting guardrail 3 is in a slightly tilted state during raising and lowering. That is, the upper end of the lifting guardrail 3 is always in a normal position, and the lower end is closer to the inner side of the bed frame. Therefore, only the lower part of the lifting guardrail 3, which is close to the inner side of the bed frame, is prone to interference with the side beams 21. The lifting clearance space 24 below the safety strip 23 can effectively avoid interference with the lower part of the lifting guardrail 3 near the bed frame, ensuring the smooth lifting of the guardrail.

[0034] The side beam 21 needs to have sufficient strength, and its dimension in the height direction is 45mm. Therefore, when it is close to the lifting guardrail 3, it is easy to interfere with the inclined lifting guardrail 3. The safety strip 23 has a dimension in the height direction of 10-14mm, and in this embodiment, it is specifically 12mm. Compared with the side beam 21 itself, it greatly reduces the contact area with the lifting guardrail. Furthermore, the safety strip 23 is set at the upper end of the side beam 21, thereby effectively avoiding interference with the inclined lifting guardrail.

[0035] To ensure sufficient clearance for the lifting guardrail 24, the safety strip 23 is 5-7mm in width along the bed board; in this embodiment, it is 6mm. This means the side beam 21 is recessed 6mm inwards relative to the safety strip 23 to effectively clear the lifting guardrail. To further enhance the clearance, a chamfer can be provided at the lower end of the safety strip 23 to accommodate the tilted lifting guardrail 3 and prevent interference.

[0036] like Figure 3 and 4 As shown, the side beam 21 and the safety strip 23 can be a separate structure, and the safety strip 23 can be nailed to the side beam 21 using nail guns. Alternatively, as shown... Figure 5 As shown, the safety strip 23 can be integrally formed with the side beam 21. Furthermore, to simplify the installation process by eliminating the need to distinguish the location of the safety strip 23 during bed board installation, safety strips 23 can be installed on both opposite sides of the bed board 2. Of course, if both side rails have a lifting function, it is necessary to install safety strips 23 on both sides of the bed board.

[0037] Furthermore, since the lifting guardrail 3 is tilted during lifting and its lower end is closer to the inside of the bed frame, it is less likely to interfere with the lifting guardrail 3 when the bed board 2 is in a higher position. Therefore, some existing cribs have to sacrifice the lifting function of the bed board and only set the bed board 2 in a high position to meet the requirements of guardrail lifting and safety. However, the bed board structure of this embodiment can retain the lifting function of the bed board at the same time, and will not interfere with the lifting guardrail 3 even when the bed board 2 is in a low position. Specifically, as shown in the figure... Figure 6 As shown, each of the opposite ends of the side beam 21 along its length is provided with a connector 25. The support railing 11 has three sets of connecting holes 117 distributed along the height direction. The connectors 25 are connected to the connecting holes 117 by bolts, and the connectors 25 can be corner brackets. This allows for three-level adjustment of the bed board height to meet user needs.

[0038] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
