Description

Technical Field

[0001] This utility model relates to the field of children's furniture technology, specifically to a crib. Background Technology

[0002] In the field of infant care, cribs, as core sleep furniture designed specifically for infants, primarily function to create a safe, comfortable sleep environment that meets the needs of healthy growth. This directly impacts an infant's sleep quality and the convenience of daily care, thus holding an irreplaceable position in family childcare scenarios. With the continuous upgrading of childcare concepts and the increasing demand for efficient use of family living space, the market has placed higher demands on the functional integration and spatial adaptability of cribs. Cribs with only a single sleep function can no longer meet the needs of modern families for multifunctional childcare products. Cribs with additional practical functions and easy storage are gradually becoming an important direction for industry research and development and consumer choice.

[0003] In response to the aforementioned market demands, various integrated baby cribs have emerged in the existing technology. For example, Chinese utility model patent CN 222194607 U discloses a baby crib with a diaper changing table function. This technology achieves stable placement of the diaper changing table by setting a locking mechanism in the crib structure, ensuring reliable support during diaper changing and other care operations. This effectively enhances the functionality of the baby crib and reduces the cost and space occupation of purchasing a separate diaper changing table in the home. Furthermore, its foldable diaper changing table design allows it to be folded away when not in use, further reducing the idle space occupied by this component. This represents a significant advancement in functional integration and space optimization.

[0004] However, the aforementioned existing technologies still have significant shortcomings in practical applications. Specifically, to achieve stable placement and folding storage of the changing table, the crib with a diaper changing table function employs a relatively complex locking mechanism and folding connection structure. This results in an increased number of structural components and complex assembly relationships, which not only increases the difficulty and cost of manufacturing but also inconveniences users in their daily operations. When unfolding or folding the changing table, users need to precisely align the locking structure and complete multiple steps, making the process cumbersome. Especially in emergency situations involving infant care, the complex procedures may delay care opportunities and reduce efficiency. Furthermore, the complex structure may also increase the difficulty of later maintenance. If a component is damaged, the ease of repair and replacement is poor, affecting the overall user experience and lifespan of the product. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] For reference as follows Figures 1-9 The present invention will be described as follows: Example: A crib includes a crib body, and a flip-up platform 1 is connected to the upper side of one side of the crib body. The platform 1 can be flipped to the upper side of the crib body for use as a diaper changing table and flipped to the side of the crib body for storage.

[0030] The bed body includes a front side panel 2, a rear side panel 3, a left side panel 4, and a right side panel 5. The bed body is formed by the four side panels, creating a rectangular frame structure with an open top and a hollow interior.

[0031] A bed board 6 is installed within the space enclosed by the front side panel 2, rear side panel 3, left side panel 4, and right side panel 5. The core function of the bed board 6 is to provide a supporting surface for the baby's sleeping position. Its installation position is lower than the top of the bed body, which can prevent the baby from accidentally slipping off the edge of the bed body while sleeping.

[0032] The changing table 1 is a key component for realizing the "diaper changing table function". It has a plate-like structure and can be switched between "use state" and "storage state" by flipping.

[0033] To achieve flipping and positioning, the structural design of the platform 1 includes two key parts: First, protruding rotating shafts 7 are set on the left and right sides of one end, which serve as the fulcrum for flipping the platform 1 and cooperate with the shaft holes 9 on the side plate of the bed body; Second, protruding positioning shafts 8 are set on the left and right sides of the other end, which cooperate with the positioning structure on the side plate of the bed body when the platform 1 is in use to ensure that the platform 1 maintains a stable horizontal state.

[0034] The front and rear sides of the facing upper surfaces of the left side plate 4 and right side plate 5 are respectively provided with shaft holes 9 that can be rotatably connected to the rotating shaft 7. The shaft holes 9 are opened on the facing upper surfaces of the left side plate 4 and right side plate 5, and one is provided on the front and one on the rear side of each side plate, that is, there are shaft holes 9 on the front side of the facing upper surface of the left side plate 4, the rear side of the facing upper surface of the right side plate 5, and the rear side of the facing upper surface of the right side plate 5. The diameter of the shaft hole 9 matches the diameter of the rotating shaft 7, ensuring that the rotating shaft 7 can be smoothly inserted into the shaft hole 9 and achieve stable rotation, and that no excessive gap is generated that would cause the platform 1 to wobble when it is flipped.

[0035] Since the left and right side panels of the bed body are equipped with shaft holes 9 on both the front and back sides, users can choose the installation position of the platform 1 according to their actual needs: if the left and right rotating shafts 7 at one end of the platform 1 are inserted into the front shaft holes 9 of the left side panel 4 and the right side panel 5 respectively, the platform 1 will be installed on the front side of the bed body; if the rotating shafts 7 are inserted into the rear shaft holes 9 of the left and right side panels, the platform 1 will be installed on the rear side of the bed body. This design requires no additional modification to the bed body; the position of the platform 1 can be adjusted simply by selecting the shaft holes 9, adapting to the childcare space layout and usage habits of different families.

[0036] When in use (as a diaper changing table), the platform 1 needs to be kept horizontal and stable, which is achieved by the cooperation of the "positioning shaft 8 and the upper positioning groove 10".

[0037] The upper surfaces of the left side plate 4 and the right side plate 5 are respectively provided with upper positioning grooves 10 that can be connected to the positioning shaft 8 (the upper positioning grooves 10 are opened on the upper surfaces of the left side plate 4 and the right side plate 5, and the groove opening size matches the diameter of the positioning shaft 8).

[0038] The upper positioning groove 10 extends through the upper sides of the left side plate 4 and the right side plate 5. This "through" design allows the user to easily insert the positioning shaft 8 directly into the groove from the upper end of the side plate when flipping the platform 1, without the need for additional angle adjustments, thus simplifying the operation process.

[0039] When the platform 1 is flipped to the upper side of the bed body, the positioning shaft 8 enters the upper positioning groove 10. The side wall of the groove limits the positioning shaft 8 in the left and right and up and down directions, so that the platform 1 cannot shift left and right or shake up and down. At this time, the platform 1 remains horizontal, and the upper surface of the platform 1 is lower than the upper end of the left side plate 4 and the right side plate 5. This height design can play a certain role in guarding and improving safety.

[0040] The upper positioning groove 10 on the left side plate 4 and the right side plate 5 can be set with one or two.

[0041] When only one upper positioning groove 10 is provided on each of the left side plate 4 and the right side plate 5, the position of this groove must be adapted to the positioning requirements of the table plate 1 when it is installed on the front or rear side of the bed body. Specifically, the groove needs to be opened at the "middle adaptation position" on the upper facing surfaces of the left and right side plates—when the table plate 1 is installed on the front side and flipped to a horizontal position, its positioning shaft 8 can be engaged in the groove; when the table plate 1 is disassembled and reinstalled on the rear side and flipped to a horizontal position, its positioning shaft 8 can also be engaged in the groove. The core advantage of this design is to reduce the number of grooves, reduce the processing difficulty of the bed body, and ensure that the table plate 1 can achieve stable positioning in different installation positions without the need to design grooves separately for different installation positions.

[0042] When two upper positioning grooves 10 are respectively provided on the left side panel 4 and the right side panel 5, the two grooves will correspond to the front and rear installation positions of the bed body, respectively. For example, an upper positioning groove 10 (front groove) is opened at the front corresponding position on the upper end of the left side panel 4, and another upper positioning groove 10 (rear groove) is opened at the rear corresponding position, and the same applies to the right side panel 5. At this time, if the platform 1 is installed on the front side of the bed body, when it is flipped to the horizontal position, its positioning shaft 8 will engage with the front groove of the front and rear side panels; if the platform 1 is installed on the rear side, the positioning shaft 8 will engage with the rear groove of the front and rear side panels. The advantage of this design is that the positioning is more precise. Each groove only fits the platform 1 in a specific installation position, which can further reduce the fit gap between the positioning shaft 8 and the groove, improve the stability of the platform 1 in use, and avoid the positioning deviation problem that may occur due to a single groove fitting two positions.

[0043] Some existing cribs only have a single sleeping function, requiring families to purchase a changing table separately, increasing costs and space usage. This solution incorporates a flip-up platform 1 on the crib itself, enabling the crib to simultaneously function as both a "sleep" and "diaper changing" station. When the platform 1 is flipped up to the top of the crib, it can be used as a changing table, eliminating the need for additional equipment and meeting the family's one-stop childcare needs. It is especially suitable for the space utilization needs of small apartments.

[0044] Compared with existing technologies (such as CN 222194607 U patent), the simplification of the structure of this solution is reflected in two core aspects: First, the increase in parts is small, with only one key component, the platform 1, added. There are no additional components such as complex locking mechanisms or folding connection components, which reduces the number of parts and assembly steps. Second, the modification of the bed body is small, requiring only the opening of shaft holes 9 and upper positioning grooves 10 on the left side plate 4 and the right side plate 5. There is no need to make structural adjustments or reinforcements to the overall frame of the bed body (such as the front side plate 2, the rear side plate 3, and the bed board 6), which reduces the difficulty and cost of manufacturing processes and reduces the risk of failure caused by complex structures.

[0045] Switching between platforms 1 and other uses requires only a single "flip": In the folded state, platform 1 is flush against the side of the bed. Users simply flip platform 1 upwards, allowing the positioning shaft 8 to engage with the upper positioning groove 10, thus switching to the usage state. After use, lift platform 1 upwards to disengage the positioning shaft 8 from the upper positioning groove 10, then flip platform 1 downwards to flush against the side of the bed, completing the folding process. The entire operation requires no precise alignment of complex interlocking structures and involves no multiple steps. Even in emergency situations involving infant care, users can quickly switch between platforms, improving care efficiency. Furthermore, the simple operating logic reduces the learning curve, making it easy for seniors, new parents, and other users to master.

[0046] The lower ends of the left side plate 4 and the right side plate 5 are respectively provided with lower positioning grooves 11 on the front and rear sides of their opposing surfaces, which can be connected to the positioning shaft 8. The lower positioning grooves 11 are provided through the front or rear sides of the left side plate 4 and the right side plate 5. The groove size of the lower positioning groove 11 matches the diameter of the positioning shaft 8, ensuring that the positioning shaft 8 can smoothly enter the groove and form a reliable limit.

[0047] When the platform 1 is not in use, the user can flip it downwards from its active position (horizontally placed on top of the bed body) until it is flush against the outer side of either the front side panel 2 or the rear side panel 3. Which side panel it flushes against depends on its installation position (if the platform 1 is installed on the front side of the bed body via the front and rear side shaft holes 9, it will flush against the outer side of the front side panel 2; if installed on the rear side, it will flush against the outer side of the rear side panel 3). During this flipping process, the positioning shaft 8 at the other end of the platform 1 moves synchronously with the flipping action, eventually entering the lower positioning groove 11. At this time, the lower positioning groove 11, through its sidewalls, constrains the positioning shaft 8 in both the left-right and up-down directions, preventing the platform 1 from shaking, shifting, or accidentally flipping while in its folded state, ensuring stability in the folded state, and also reducing collision and wear between the platform 1 and the bed body side panels.

[0048] The other end of the platform 1 is provided with operating holes 12 that extend through both sides of its thickness direction. To reduce the difficulty of applying force when flipping the platform 1, operating holes 12 that extend through both sides of its thickness direction are provided at the other end of the platform 1 (i.e., the end away from the rotating shaft 7). The position of the operating holes 12 needs to meet ergonomic requirements, and is usually located in the middle area of ​​that end of the platform 1, ensuring that the user's fingers (one or two fingers) can be easily inserted into the holes.

[0049] When the platform 1 needs to be flipped (whether from a stored state to a used state, or vice versa), the user can insert their finger into the operating hole 12 and apply an upward or downward force to drive the platform 1 to rotate around the rotation axis 7. The core function of this design is to provide a clear point of force application. The operating hole 12 ensures that the user can still apply force stably, further optimizing the ease of operation and reducing the intensity of operation.

[0050] The left and right sides of the front and rear end faces of the bed board 6 are respectively provided with protruding connecting posts 13 (the connecting posts 13 and the bed board 6 are an integral structure, and their outer diameter matches the inner diameter of the connecting holes 14 opened on the front side plate 2 and the rear side plate 3, ensuring that the connecting posts 13 can be tightly inserted into the connecting holes 14 to form a stable plug-in connection). The front side plate 2 and the rear side plate 3 are respectively provided with connecting holes 14 corresponding to the connecting posts 13. The bed board 6 is connected to the connecting holes 14 on the front side plate 2 and the rear side plate 3 through the connecting posts 13, thus realizing the fixation of the bed board 6.

[0051] During installation, simply align the connecting posts 13 at both ends of the bed board 6 with the corresponding connecting holes 14 on the front side panel 2 and the rear side panel 3, and insert them to secure the bed board 6. During disassembly, simply pull the bed board 6 outwards to disengage the connecting posts 13 from the connecting holes 14. This connection method eliminates the need for additional screws, clips, or other fasteners, simplifying the installation and disassembly process of the bed board 6 and facilitating subsequent cleaning and maintenance of the bed board 6 or the interior of the bed body.

[0052] Both the front side panel 2 and the rear side panel 3 have multiple connecting holes 14 spaced apart along the vertical direction. The connecting posts 13 on the bed board 6 are connected to the connecting holes 14 at different heights, which allows the height of the bed board 6 to be adjusted.

[0053] To meet the needs of infants at different stages of growth (e.g., a higher bed board is needed for easy picking up in the newborn stage, and a lower bed board is needed to prevent climbing and falling after the infant can roll over and sit up), multiple connecting holes 14 are spaced apart along the vertical direction on both the front side panel 2 and the rear side panel 3. The diameter of the multiple connecting holes 14 is the same, and the vertical spacing needs to be reasonably designed according to the height and activity level of the infant at different stages of growth (to ensure that different height settings can be effectively adapted to different usage scenarios).

[0054] When the height of the bed board 6 needs to be adjusted, first disassemble the bed board 6 (disconnecting the connecting post 13 from the current connecting hole 14), then select the corresponding height connecting hole 14 on the front side panel 2 or the rear side panel 3 according to the needs, and finally insert the connecting post 13 of the bed board 6 into the newly selected connecting hole 14 to complete the height adjustment of the bed board 6. This design does not require structural modification of the bed board 6 or the side panels; height adjustment can be achieved simply by changing the connection position. It is simple to operate, highly adaptable, and can extend the overall lifespan of the crib.

[0055] To enhance the load-bearing capacity and structural stability of the bed board 6, connecting grooves 15 extending through its front and rear sides are provided on the left and right sides of the lower side of the bed board 6. Elongated support rods 16 are connected within these grooves 15 (the support rods 16 can be fully embedded in the connecting grooves 15, and their lower surfaces do not protrude from the lower surface of the bed board 6 after embedding). The front side panel 2 and rear side panel 3 are respectively provided with insertion holes 17 corresponding to the height and number of their connecting holes 14. Both ends of the support rods 16 are inserted into these insertion holes 17. By providing support rods 16 on the lower side of the bed board 6, the support for the bed board 6 is further strengthened. Simultaneously, the insertion holes 17 allow the support rods 16 to change their insertion positions with the front side panel 2 and rear side panel 3 as the height of the bed board 6 is adjusted.

[0056] During installation, insert the support rod 16 into the connecting groove 15 from the front or rear end of the bed board 6 until the support rod 16 is completely in contact with the inner wall of the connecting groove 15. At this time, the support rod 16 and the bed board 6 form an integrated structure, which can jointly bear the weight of the baby and external pressure, effectively preventing the bed board 6 from bending or deforming due to excessive local stress.

[0057] To further fix the position of the support rod 16 and ensure that the support rod 16 can be adjusted synchronously with the height adjustment of the bed board 6, insertion holes 17 corresponding to the height and number of their respective connection holes 14 are provided on the front side plate 2 and the rear side plate 3. That is, there is an insertion hole 17 directly below (or at the corresponding height position) each connection hole 14, and the diameter of the insertion hole 17 matches the outer diameter of the support rod 16.

[0058] After the bed board 6 is fixed to the connecting hole 14 at a certain height via the connecting post 13, the two ends of the support rod 16 are aligned with the corresponding insertion holes 17 on the front side panel 2 and the rear side panel 3 and inserted to fix the support rod 16. This design allows the support rod 16 to not only provide support for the bed board 6 from below, but also to further enhance the connection stability between the bed board 6 and the bed frame through its connection with the front side panel 2 and the rear side panel 3. At the same time, since the insertion holes 17 and the connecting holes 14 are at the same height, when the height of the bed board 6 is adjusted, the support rod 16 can simply be pulled out of the current insertion hole 17, adjusted to the new height with the bed board 6, and then inserted into the corresponding insertion hole 17, ensuring that the support reinforcement structure always matches the height of the bed board 6 and continues to play its supporting role.

[0059] The front panel 2, rear panel 3, left side panel 4, and right side panel 5 are each equipped with grille holes 18. The grille holes 18 are typically circular, rectangular, or strip-shaped. The core function of the grille holes 18 is to allow air circulation between the inside and outside of the crib, reducing stuffiness inside and creating a more comfortable sleeping environment for the baby. At the same time, the grille holes 18 also allow parents to easily observe the baby's sleeping state from the outside of the crib without opening the crib railings or approaching the crib itself, minimizing disturbance to the baby's sleep.

[0060] Rollers 19 are provided on the underside of the left side panel 4 and the right side panel 5. Usually, two are installed on each side, located at the front and rear ends respectively. The rollers 19 adopt a universal wheel structure with a braking function. The wheel body material is usually wear-resistant rubber or plastic to ensure that the rollers 19 can roll smoothly on different surfaces (such as wooden floors, tiles, and carpets) and with less noise when rolling, so as not to disturb the baby.

[0061] A bottom plate 20 is provided in the space enclosed by the front side plate 2, the rear side plate 3, the left side plate 4, and the right side plate 5. The bottom plate 20 is located under the bed board 6, and its edge is fixedly connected to the inner wall of the four side plates.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
