[0002] This application claims priority to Chinese Patent Application No. 202411628176.1, filed on November 14, 2024, entitled "Foldable Children's Bed", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of children's products technology, and in particular to a foldable children's bed. Background Technology

[0004] A crib is a safe place for a baby to sleep and play, and can be used at home or while traveling. A crib also creates a safe area for the baby, especially when they can crawl or are particularly curious. For minimal space usage and ease of movement, cribs are usually designed to be foldable.

[0005] However, existing foldable children's beds are cumbersome, laborious, and not flexible enough to fold up. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a foldable children's bed.

[0007] This application provides a foldable children's bed, which may include: multiple upper corner members and multiple foldable upper crossbars, the multiple upper crossbars and multiple upper corner members forming a closed upper railing, and adjacent upper crossbars being rotatably connected by the upper corner members; multiple lower corner members and multiple uprights, one end of each upright being connected to an upper corner member and the other end being connected to a lower corner member; a locking mechanism including a housing and a locking rod, the housing including a first surface facing away from the upper railing and a second surface facing the upper railing, the housing defining a guide channel extending in a direction from the first surface to the second surface, the guide channel penetrating the first surface to form a first opening, and the locking rod... The device includes a first rod segment and a second rod segment connected together. The first rod segment extends slidably into the guide channel through the first opening, and the second rod segment is located outside the first surface. It also includes multiple lower crossbars, one end of which is rotatably connected to the lower corner member, and the other end of which is rotatably connected to the outer shell. Furthermore, it includes multiple connecting rods, one end of which is rotatably connected to the second rod segment, and the other end of which is rotatably connected to the lower crossbars. The locking rod includes a first position and a second position. When the locking rod is in the first position, all the first rod segments are located within the guide channel, and the foldable children's bed is in use. When the locking rod is in the second position, at least a portion of the first rod segment is located outside the first opening, and the foldable children's bed is in a folded state.

[0008] It should be noted that when the locking rod is in the first position, the foldable children's bed is in use. When the locking rod moves from the first position to the second position, the locking rod moves downward relative to the outer shell, causing the connecting rod to drag the lower crossbar. Under the pull of the connecting rod, the lower crossbar rotates downward and towards the direction of the outer shell, that is, multiple lower crossbars are retracted towards the locking mechanism. During this process, the distance between the lower corner components decreases, the upper crossbar folds, and the distance between the upper corner components decreases to cooperate with the retraction of the lower crossbars, until the locking rod moves to the second position. At this time, the lower crossbar, uprights, and upper crossbars all extend roughly in the vertical direction. At this point, the foldable children's bed is in a folded state, occupying minimal space and facilitating user storage.

[0009] In this way, the foldable children's bed provided by this application can switch between the use state and the folded state because the locking rod can slide between the first position and the second position relative to the guide channel. The user only needs to pull the locking rod to move from the first position to the second position. The folding operation is simple and effortless.

[0010] In some embodiments of this application, the radial dimension of the second rod segment is greater than the radial dimension of the first opening, and when the locking rod is in the second position, the second rod segment abuts against the first surface.

[0011] In some embodiments of this application, a connecting pin is provided on the circumferential outer side of the second rod segment. The connecting pin extends toward the circumferential outer side of the second rod segment, and the connecting pin is rotatably connected to the connecting rod. The connecting pin corresponds one-to-one with the connecting rod.

[0012] In some embodiments of this application, a guide groove is provided on one of the inner wall of the guide channel and the outer wall of the locking rod, and a guide protrusion that cooperates with the guide groove is provided on the other; wherein, the guide groove extends in the direction from the first surface toward the second surface.

[0013] In some embodiments of this application, the guide channel penetrates the second surface to form a second opening, and the end of the first rod segment near the second opening is provided with a locking groove recessed toward the first surface. The inner wall of the locking groove is provided with a locking crossbar. The locking mechanism further includes an unlocking component, which includes a connected rotating part and a locking part. The rotating part is rotatably mounted on the second opening, and the locking part extends into the second opening. The locking part is provided with a locking notch that can engage with the locking crossbar. The unlocking component includes a locking position and an unlocking position. The unlocking component can rotate between the locking position and the unlocking position. When the unlocking component is in the locking position, the locking crossbar engages with the locking notch, and the locking rod is fixed in the first position. When the unlocking component is in the unlocking position, the locking crossbar disengages from the locking groove, and the locking rod can move between the first position and the second position.

[0014] In some embodiments of this application, the unlocking member further includes a handheld portion connected to the rotating portion and located outside the second opening.

[0015] In some embodiments of this application, when the unlocking member is in the locked position, the extension direction of the handheld portion is parallel to the second surface.

[0016] In some embodiments of this application, the second surface is provided with a relief groove, and the second opening is formed in the bottom wall of the relief groove. When the unlocking member is in the locked position, the handheld part is located in the relief groove.

[0017] In some embodiments of this application, the unlocking component further includes a rotating shaft and a torsion spring. The rotating shaft passes through the inner wall of the rotating part and the clearance sink, and the torsion spring is sleeved on the rotating shaft. One torsion arm of the torsion spring abuts against the rotating part, and the other torsion arm abuts against the inner wall of the clearance sink.

[0018] In some embodiments of this application, a tension hole is provided at the end of the hand-held part away from the rotating part, and the tension hole is used to thread a pull rope through. Attached Figure Description

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0029] A crib is a safe place for a baby to sleep and play, and can be used at home or while traveling. A crib also creates a safe area for the baby, especially when they can crawl or are particularly curious. For minimal space usage and ease of movement, cribs are usually designed to be foldable.

[0030] However, existing foldable children's beds are cumbersome, laborious, and not flexible enough to fold up.

[0031] To address the aforementioned technical problems, please refer to Figure 1, which is a schematic diagram of a foldable children's bed provided in some embodiments of this application. This application provides a foldable children's bed 100, which may include multiple upper corner members 110, multiple foldable upper crossbars 120, multiple lower corner members 130, multiple uprights 140, a locking mechanism 150, multiple lower crossbars 160, and multiple connecting rods 170.

[0032] Specifically, multiple upper horizontal bars 120 and multiple upper corner members 110 form a closed upper fence. Adjacent upper horizontal bars 120 are rotatably connected by upper corner members 110. Each upper horizontal bar 120 may include two sub-upper horizontal bars, which are rotatably connected. Specifically, the two sub-horizontal bars can be rotatably connected by a rotating connector 121. The upper horizontal bar 120 can also be formed as a foldable flexible bar.

[0033] One end of the upright 140 is connected to the upper corner member 110, and the other end is connected to the lower corner member 130. A steering wheel 180 can be provided below the lower corner member 130 to allow the foldable children's bed 100 to move. The number of upper corner members 110, upper crossbars 120, lower corner members 130, and uprights 140 can be the same. Specifically, the foldable children's bed 100 is formed as a cuboid, with four upper corner members 110, four upper crossbars 120, four lower corner members 130, and four uprights 140. Thus, the skeleton of the foldable children's bed 100 is formed by multiple upper corner members 110, multiple upper crossbars 120, multiple lower corner members 130, and multiple uprights 140.

[0034] Of course, in some other embodiments, the number of upper corner members 110, upper crossbar 120, lower corner members 130 and uprights 140 may also be different because the frame shape of the foldable children's bed 100 (e.g., formed as a circle, square or the like) changes.

[0035] Please refer to Figures 2 and 3. Figure 2 is a top view of the locking mechanism shown in Figure 1; Figure 3 is a cross-sectional view of the locking mechanism shown in Figure 2 at point AA. The locking mechanism 150 may include a housing 151 and a locking lever 152. The housing 151 includes a first surface facing away from the upper fence and a second surface facing the upper fence. A guide channel is defined within the housing 151. The guide channel extends in a direction from the first surface toward the second surface (e.g., the up-down direction shown in Figure 1). The guide channel extends through the first surface to form a first opening. The locking lever 152 includes a first lever segment 1521 and a second lever segment 1522 connected together. The first lever segment 1521 extends slidably into the guide channel through the first opening, and the second lever segment 1522 is located outside the first surface.

[0036] One end of the lower crossbar 160 is rotatably connected to the lower corner component 130, and the other end is rotatably connected to the outer casing 151. The number of lower crossbars 160 is the same as the number of lower corner components 130.

[0037] In the specific implementation process, please continue to refer to Figures 1 to 3. Two lower crossbars 160 can be grouped together, and the two lower crossbars 160 in a group are spaced apart in the vertical direction. The number of lower crossbars 160 is twice the number of lower corner components 130. This can ensure the stability of the lower crossbars 160 during rotation and the stability of the support of the lower crossbars 160.

[0038] One end of the connecting rod 170 is rotatably connected to the second rod segment 1522, and the other end is connected to the lower crossbar 160.

[0039] As the frame shape of the foldable children's bed 100 changes (e.g., it is formed into a circle, a square, etc.), the number of the lower corner member 130, the lower crossbar 160, and the connecting rod 170 can be specifically adjusted.

[0040] Specifically, the locking mechanism 150 can be located at the center of multiple lower corner members 130. Taking the number of lower corner members 130 as an example, the number of lower crossbars 160 is also 4. The 4 lower crossbars 160 intersect at the position of the locking mechanism 150 to form an "X" shaped structure.

[0041] The locking lever 152 includes a first position and a second position. When the locking lever 152 is in the first position, the first segment 1521 is located in the guide channel and the foldable children's bed 100 is in use. When the locking lever 152 is in the second position, at least a portion of the first segment 1521 is located outside the first opening and the foldable children's bed 100 is in a folded state.

[0042] It should be noted that when the locking rod 152 is in the first position, the foldable children's bed 100 is in use. When the locking rod 152 moves from the first position to the second position, the locking rod 152 moves downward relative to the outer shell 151, which drives the connecting rod 170 to drag the lower crossbar 160. Under the pull of the connecting rod 170, the lower crossbar 160 rotates downward and towards the direction of the outer shell 151. That is, multiple lower crossbars 160 are retracted towards the locking mechanism 150. During this process, the distance between the lower corner members 130 decreases, the upper crossbar 120 folds, and the distance between the upper corner members 110 decreases to cooperate with the retraction of the lower crossbar 160 until the locking rod 152 moves to the second position. At this time, the lower crossbar 160, the upright 140, and the upper crossbar 120 all extend roughly in the vertical direction. At this point, the foldable children's bed 100 is in a folded state, occupying the least space and making it convenient for users to store.

[0043] In this way, the foldable children's bed 100 provided in this application can switch between the use state and the folded state because the locking rod 152 can slide between the first position and the second position relative to the guide channel. The user only needs to pull the locking rod 152 to move it from the first position to the second position. The folding operation is simple and effortless.

[0044] In some embodiments of this application, referring to Figure 2, the radial dimension of the second rod segment 1522 is larger than the radial dimension of the first opening. When the locking rod 152 is in the second position, the second rod segment 1522 abuts against the first surface. It can be understood that during the process of the locking rod 152 moving from the second position to the first position, the second rod segment 1522 moves towards the first surface. Setting the radial dimension of the second rod segment 1522 to be larger than the first opening can prevent the second rod segment 1522 from moving into the guide channel. This can prevent the locking rod 152 from exceeding the first position (i.e., the locking rod 152 moves to the side of the first position away from the second position) during the process of moving from the second position to the first position, thus preventing the foldable children's bed 100 from shaking up and down during use and ensuring the stability of the foldable children's bed 100 in the use state.

[0045] In some embodiments of this application, please refer to Figures 2 to 4, where Figure 4 is a schematic diagram of the locking rod and unlocking element shown in Figure 3. A connecting pin 1523 is provided on the circumferential outer side of the second rod segment 1522. The connecting pin 1523 extends outward from the circumferential outer side of the second rod segment 1522 and is rotatably connected to the connecting rod 170, with each connecting pin 1523 corresponding to one connecting rod 170. Thus, the connecting pin 1523 provides an installation position for the rotatable connection of the connecting rod 170.

[0046] Taking the example of four lower corner components 130, four lower crossbars 160, four connecting rods 170, and four connecting pins 1523, the connecting pins 1523 extend along the diagonal of the quadrilateral formed by the lower corner components 130, allowing the two opposite lower crossbars 160 to rotate on the plane, thereby enhancing the stability of the lower crossbars 160 rotating between the use state and the folded state of the foldable children's bed 100.

[0047] In some embodiments of this application, please refer to Figures 3 and 4. The guide channel penetrates the second surface to form a second opening. The first rod segment 1521 is provided with a snap-fit ​​groove 1525 recessed toward the first surface at one end near the second opening. The inner wall of the snap-fit ​​groove 1525 is provided with a snap-fit ​​crossbar 1526. Specifically, the snap-fit ​​groove 1525 may include a first inner wall and a second inner wall opposite to each other in a first direction. The snap-fit ​​crossbar 1526 extends from the first inner wall toward the second inner wall and connects the first inner wall and the second inner wall.

[0048] The locking mechanism 150 may further include an unlocking member 153. The unlocking member 153 may include a connected rotating part 1531 and a locking part 1532. The rotating part 1531 is rotatably mounted on the second opening, and the locking part 1532 extends into the second opening. The locking part 1532 is provided with a locking notch 1533 that can engage with the locking crossbar 1526. The unlocking member 153 includes a locking position and an unlocking position. The unlocking member 153 can rotate between the locking position and the unlocking position. When the unlocking member 153 is in the locking position, the locking crossbar 1526 engages with the locking notch 1533, and the locking bar 152 is fixed in the first position. When the unlocking member 153 is in the unlocking position, the locking crossbar 1526 disengages from the locking groove 1525, and the locking bar 152 can move between the first position and the second position.

[0049] Therefore, by setting the unlocking component 153, the locking rod 152 can be fixed in the first position, thereby ensuring the stability of the foldable children's bed 100 in use. When the user needs to fold the foldable children's bed 100, the unlocking component 153 needs to be rotated from the locked position to the unlocked position to avoid the foldable children's bed 100 being accidentally folded.

[0050] In some embodiments of this application, please continue to refer to Figures 2 to 4. The unlocking member 153 also includes a handle 1534, which is connected to the rotating part 1531 and located outside the second opening. Thus, by providing the handle 1534, it is convenient for the user to rotate the unlocking member 153 between the locked position and the unlocked position. At the same time, after the user rotates the unlocking member 153 to the unlocked position, he can pull the outer shell 151 through the handle 1534, so that the outer shell 151 and the locking rod 152 move relative to each other, so that the locking rod 152 moves from the first position to the second position, realizing the switching of the foldable children's bed 100 from the use state to the folded state.

[0051] In some embodiments of this application, when the unlocking member 153 is in the locked position, the extension direction of the handle 1534 is parallel to the second surface. It is understood that when the unlocking member 153 is in the locked position, the locking rod 152 is in the first position, the child foldable bed is in use, and the extension direction of the handle 1534 is parallel to the second surface, ensuring the relative flatness of the second surface, avoiding obvious protrusions on the bed surface, and ensuring a good user experience.

[0052] Optionally, referring to Figures 3 and 4, the second surface is provided with a relief groove 154, and a second opening is formed in the bottom wall of the relief groove 154. When the unlocking member 153 is in the locked position, the handle 1534 is located within the relief groove 154. Therefore, by providing the relief groove 154, the second surface can be kept flat when the unlocking member 153 is in the locked position, i.e., when the child folding bed is in use, preventing any protrusions on the bed surface and further ensuring a good user experience.

[0053] In some embodiments of this application, please continue to refer to Figures 3 and 4. The unlocking component 153 further includes a rotating shaft and a torsion spring 1535. The rotating shaft passes through the inner wall of the rotating part 1531 and the clearance groove 154. The torsion spring 1535 is sleeved on the rotating shaft. One torsion arm of the torsion spring 1535 abuts against the rotating part 1531, and the other torsion arm abuts against the inner wall of the clearance groove 154. Thus, by providing the torsion spring 1535, the unlocking component 153 can be automatically reset from the unlocked position to the locked position.

[0054] In some embodiments of this application, please continue to refer to Figures 3 and 4. The end of the handle 1534 away from the rotating part 1531 is provided with a pull hole 1536 for threading a pull cord. Thus, by threading a pull cord, the lever arm of the handle 1534 can be extended, thereby reducing the force required for the user to rotate the unlocking member 153 and pull the outer shell 151. At the same time, the pull cord design facilitates user operation.

[0055] In some embodiments of this application, please refer to Figure 5, which is a bottom view of the locking structure shown in Figure 1. A guide groove 1524 is provided on one of the inner wall of the guide channel and the outer wall of the locking rod 152, and a guide protrusion 1511 that mates with the guide groove 1524 is provided on the other. The guide groove 1524 extends from the first surface toward the second surface (i.e., the up-down direction shown in Figure 5). Therefore, by providing the cooperating guide groove 1524 and guide protrusion 1511, the circumferential rotation of the locking rod 152 during its movement between the first and second positions can be avoided, further ensuring the stability of the locking rod 152's movement between the first and second positions, improving product quality, and enhancing the user experience.

[0056] Specifically, the inner wall of the guide channel may be provided with a guide groove 1524 and the outer wall of the locking rod 152 may be provided with a guide protrusion 1511, or the inner wall of the guide channel may be provided with a guide protrusion 1511 and the outer wall of the locking rod 152 may be provided with a guide groove 1524.

[0057] Optionally, there can be multiple guide grooves 1524 and multiple guide protrusions 1511, with each guide groove 1524 corresponding to a guide protrusion 1511.

[0058] In some embodiments of this application, please continue to refer to FIG1. ​​The foldable children's bed 100 may also include an auxiliary rod 190. One end of the auxiliary rod 190 is rotatably connected to the outer shell 151, and the other end is bent or tilted toward the ground. When the foldable children's bed 100 is in use, the auxiliary rod 190 can act as a bed leg to further ensure the stability of the foldable children's bed 100 during use.

[0059] The auxiliary rod 190 may include multiple rods.
