Description

FIELD OF THE INVENTION

[0001] The utility model relates to a means of transport for children, in particular to a foldable sleeping basket and a stroller comprising the foldable sleeping basket. TECHNOLOGICAL BACKGROUND

[0002] Some strollers are popular with consumers because they can be equipped with both infant seats and bassinets for carrying younger babies. Most bassinets adapted to existing strollers can only rely on the upper frame and lower frame of the raising and lowering device to achieve folding. The length cannot be folded, and the fabric cover of the foldable bassinet must be removed, and the rod must be manually operated to release the support between the upper and lower frames. This process is extremely cumbersome. A small number of bassinet products can be folded lengthwise, adopting a two-stage folding, and the bassinet folds into a V-shape.Because the frame of the sleeping basket and the folding joint itself take up a certain amount of space after folding, the end of the frame farther from the folding joint has a larger opening angle and takes up a certain amount of space. Furthermore, excessive compression can damage the fabric cover at the joints. CONTENTS OF THE UTILITY MODEL

[0003] This utility model provides a foldable sleeping basket and a stroller incorporating the foldable sleeping basket to solve the existing technical problems that the end of the sleeping basket rod facing away from the folding joint has a larger opening angle, a certain space is occupied, and forcible compression may damage the fabric cover at the joints after the sleeping basket is folded and closed.

[0004] The utility model is designed to solve the above-mentioned technical problems through the following technical features: A foldable sleeping basket is provided, comprising an upper frame, a lower frame, and a folding device. The upper frame comprises a first upper frame, a second upper frame, and a first foldable part, wherein the first upper frame is connected to the second upper frame via the first foldable part. The first upper frame and the second upper frame can each be folded toward each other via the pivot point at the connection to the first foldable part.The lower frame comprises a first lower frame, a second lower frame, and a third lower frame, wherein the first lower frame can be rotated and connected to one end of the third lower frame, the second lower frame can be rotated and connected to the other end of the third lower frame, and the first lower frame and the second lower frame can each be folded towards each other via the pivot point at the connection to the third lower frame. The folding device comprises a first foldable part and a second foldable part, wherein the first foldable part is arranged between the first upper frame and the first lower frame, and the second foldable part is arranged between the second upper frame and the second lower frame.When the first upper frame and the second upper frame are folded toward each other, the first lower frame and the second lower frame are folded toward each other, driven by the first foldable part and the second foldable part.

[0005] In this concept, the first upper frame is connected to the second upper frame via the first foldable part and can also be folded upward via the pivot point at the connection with the first foldable part. The first lower frame and the second lower frame can each be folded towards each other via the pivot point at the connection with the third lower frame. In addition, a first foldable part is arranged between the first upper frame and the first lower frame, and a second foldable part is arranged between the second upper frame and the second lower frame. When the first upper frame is folded upward via the pivot point at the connection with the first foldable part, the first foldable part drives the first lower frame, which is folded upward via the pivot point at the connection with the third lower frame.When the second upper frame is folded up, the second upper frame similarly drives the third lower frame to fold down to reduce the space occupied by the sleeping basket and facilitate storage. When the foldable sleeping basket needs to be unfolded for use, the first upper frame and the second upper frame are pulled, causing the first lower frame and the second lower frame to unfold. Because the third lower frame is arranged between the first lower frame and the second lower frame, the lower frame is folded into three sections, and the third lower frame creates more space between the first lower frame and the second lower frame. Firstly, after folding, the first lower frame, the second lower frame, and the third lower frame form a U-shape, taking up less space compared to the two-section V-shaped frame.On the other hand, the head and fabric cover are less susceptible to damage from compression and are flatter after the sleeping basket is folded.

[0006] Preferably, the foldable sleeping basket also includes a locking mechanism. The locking mechanism serves to lock the first foldable part to prevent the first upper frame and the second upper frame, as well as the first lower frame and the second lower frame, from folding together.

[0007] In this concept, the locking mechanism locks the first foldable part when the sleeping basket is unfolded for use, and the first upper frame and the second lower frame cannot be folded. Since the first lower frame and the second lower frame are connected to the first upper frame and the second upper frame via the first foldable part and the second foldable part, the first lower frame and the second lower frame cannot be folded when the first upper frame and the second upper frame cannot be folded. Compared with relying on the fixing scope of the pivot point to maintain the use status of the sleeping basket, the above structure is safer and more stable.

[0008] Preferably, a release mechanism is arranged on the upper frame or the lower frame, and the release mechanism can unlock the locking mechanism.

[0009] In this concept, a release mechanism is located on the upper frame and the lower frame. Compared to manually unlocking the locking mechanism on both sides, even when removing the fabric cover of the sleeping basket to operate the first folding section and the second folding section, this process is more convenient and easier.

[0010] Preferably, the first foldable part comprises a first connecting rod and a first support rod, wherein one end of the first support rod can be rotated and connected to the first upper frame and the other end of the first support rod can be rotated and connected to the third lower frame.The first connecting rod comprises a first sub-rod, a second sub-rod, and a third sub-rod, wherein the middle part of the third sub-rod can be rotated and connected to the middle part of the first support rod, one end of the third sub-rod can be rotated and connected to one end of the first sub-rod, the other end of the third sub-rod can be rotated and connected to one end of the second sub-rod, the other end of the first sub-rod can be rotated and connected to the part of the first bendable part near the first bendable part, and the other end of the second sub-rod can be rotated and connected to the part of the third lower frame that is remote from the third lower frame.The second foldable part comprises a second connecting rod, wherein one end of the second connecting rod can be rotated and connected to the second upper frame and the other end of the second connecting rod can be rotated and connected to the second lower frame.

[0011] In this concept, the second lower frame is driven to fold upward when the second upper frame is folded upward. At the same time, the second upper frame exerts a downward force on the end of the first upper frame near the first foldable part to move the first sub-bar downward over the first foldable part.

[0012] In addition, the middle part of the third sub-rod can be rotated and connected to the middle part of the first support rod. When the first sub-rod moves downward, the third sub-rod is driven to rotate at the connection between the third sub-rod and the first support rod. Since the third sub-rod can be rotated and connected to the second sub-rod, the first sub-rod can be rotated and connected to the first upper frame, and the second sub-rod can be rotated and connected to the first lower frame. When the third sub-rod rotates, the second sub-rod is pulled to drive the first lower frame to fold upward. In addition, the first support rod is fixed and connected to the third lower frame.When folded, the first upper frame, the second upper frame, the first lower frame and the second lower frame are at the same angle of inclination to the first support bar, so that the sleeping basket can be tilted in one direction and fitted into the vehicle frame for convenient storage.

[0013] Preferably, the second foldable part also comprises a third connecting rod, wherein one end of the third connecting rod can be rotated and connected to the second upper frame and the other end of the third connecting rod can be rotated and connected to the third lower frame.

[0014] With this concept, the other end of the third connecting rod can be rotated and connected to the third lower frame. The connections between the second foldable part and the upper / lower frames are evenly distributed, making the structure more stable and reliable, and less prone to deformation.

[0015] Preferably, the first foldable part comprises a first connecting rod, wherein one end of the first connecting rod can be rotated and connected to the first upper frame and the other end of the first connecting rod can be rotated and connected to the first lower frame.

[0016] In this concept, the first foldable part is connected to the folding movement of the first upper frame and the first lower frame via the first connecting rod arranged between the first upper frame and the first lower frame, which enables a simple structure and lower production costs.

[0017] Preferably, the first foldable part also comprises a second connecting rod, wherein one end of the second connecting rod can be rotated and connected to the first upper frame and the other end of the second connecting rod can be rotated and connected to the connection between the first lower frame and the third lower frame.

[0018] In this concept, the other end of the second connecting rod can be rotated and connected to the joint between the first lower frame and the third lower frame. The joints between the first foldable part and the upper / lower frame are evenly distributed. Therefore, the structure is more stable and reliable, and less prone to deformation.

[0019] Preferably, the second foldable part is arranged symmetrically with the first foldable part.

[0020] In this concept, the second foldable section is arranged symmetrically with the first. The sleeping basket is simple in design and inexpensive to manufacture.

[0021] Preferably, the first foldable part comprises a first connecting rod and a second connecting rod, wherein one end of the second connecting rod can be rotated and connected to the first upper frame and the other end of the second connecting rod can be rotated and connected to the connection between the first lower frame and the third lower frame.The first connecting rod comprises a first sub-rod, a second sub-rod, and a third sub-rod, wherein the middle part of the third sub-rod can be rotated and connected to the middle part of the second connecting rod, one end of the third sub-rod can be rotated and connected to one end of the first sub-rod, the other end of the third sub-rod can be rotated and connected to one end of the second sub-rod, the other end of the first sub-rod can be rotated and connected to the part of the first upper frame near the first bendable part, and the other end of the second sub-rod can be rotated and connected to the part of the first lower frame that is remote from the third lower frame.

[0022] In this concept, both ends of the second connecting rod can be rotated and connected to the first upper frame and the connection between the first lower frame and the third lower frame. When the first upper frame is folded upward, the second connecting rod is driven to rotate via the pivot point at the connection between the first lower frame and the third lower frame. In addition, the middle part of the third sub-rod can be rotated and connected to the middle part of the second connecting rod. When the second connecting rod rotates, the third sub-rod is driven to rotate at the connection between the third sub-rod and the second connecting rod.Because the third sub-rod can be rotated and connected to the first sub-rod and the second sub-rod, the first sub-rod can be rotated and connected to the first upper frame, and the second sub-rod can be rotated and connected to the first lower frame. When the third sub-rod rotates, the second sub-rod is pulled to drive the first lower frame, causing it to fold upward. In the structure, the first foldable part is X-shaped, with uniform load at the connections with the first upper frame and the first lower frame. The structure is more stable and reliable.

[0023] Preferably, the second foldable part is arranged symmetrically with the first foldable part.

[0024] The second foldable section is arranged symmetrically with the first. The sleeping basket is simple in design and inexpensive to manufacture.

[0025] A stroller that also includes a foldable sleeping basket.

[0026] In this concept, for the sleeping basket on the stroller, the first upper frame is connected to the second upper frame via the first foldable part and can also be folded upward via the pivot point at the connection with the first foldable part. The first lower frame and the second lower frame can each be folded towards each other via the pivot point at the connection with the third lower frame. Moreover, the first foldable part is arranged between the first upper frame and the first lower frame, and the second foldable part is arranged between the second upper frame and the second lower frame. When the first upper frame is folded upward via the pivot point at the connection with the first foldable part, the first foldable part drives the first lower frame, which is folded upward via the pivot point at the connection with the third lower frame.Similarly, when the second upper frame is folded up, the second lower frame is driven to fold down so that the sleeping basket takes up less space for easier storage. When the foldable sleeping basket needs to be unfolded for use, the first upper frame and the second upper frame are pulled, which drives the unfolding of the first lower frame and the second lower frame. Because the third lower frame is placed between the first lower frame and the second lower frame, the lower frame is folded into three sections, and the third lower frame creates more space between the second lower frame and the second lower frame. Firstly, the first lower frame, the second lower frame, and the third lower frame form a U-shape after being folded, taking up less space compared to the two-section V-shaped frame.On the other hand, the head and fabric cover are less susceptible to damage due to compression and are flatter after the sleeping basket is folded.

[0027] A preferred embodiment is given below together with the accompanying drawings for a clearer and more complete description of the utility model. Embodiment 1

[0028] As in the Fig. 1 to 6, this embodiment 1 of the utility model provides a foldable sleeping basket comprising an upper frame (1), a lower frame (2), and a folding device. The upper frame (1) comprises a first upper frame (11), a second upper frame (12), and a first foldable part (13), wherein the first upper frame (11) is connected to the second upper frame (12) via the first foldable part (3). The first upper frame (11) and the second upper frame (12) can be folded towards one another via the pivot point at the connection to the first foldable part (13).The lower frame (2) comprises a first lower frame (21), a second lower frame (22), and a third lower frame (23), wherein the first lower frame (21) can be rotated and connected to one end of the third lower frame (23), the second lower frame (22) can be rotated and connected to the other end of the third lower frame (23), and the first lower frame (21) and the second lower frame (22) can each be folded towards one another via the pivot point at the connection to the third lower frame (23). The folding device comprises a first foldable part (31) and a second foldable part (32), wherein the first foldable part (31) is arranged between the first upper frame (11) and the first lower frame (21), and the second foldable part (32) is arranged between the second upper frame (12) and the second lower frame (22).When the first upper frame (11) and the second upper frame (21) are folded toward each other, the first lower frame (21) and the second lower frame (22) are folded toward each other, driven by the first foldable part (31) and the second foldable part (32).

[0029] In this concept, the first upper frame (11) is connected to the second upper frame (12) via the first foldable part (13) and can also be folded upwards via the pivot point at the connection to the first foldable part (13). The first lower frame (21) and the second lower frame (22) can each be folded towards each other via the pivot point at the connection to the third lower frame (23). In addition, the first foldable part (31) is arranged between the first upper frame (11) and the first lower frame (21), and the second foldable part (32) is arranged between the second upper frame (12) and the second lower frame (22). When the first upper frame (11) is folded upwards over the pivot point at the connection with the first foldable part (13), the first foldable part (31) drives the first lower frame (21) to be folded upwards over the pivot point at the connection with the third lower frame (23).Similarly, when the second upper frame (12) is folded upwards, the second lower frame (22) is driven to fold downwards to reduce the space required by the sleeping basket for easy storage. When the foldable sleeping basket needs to be unfolded for use, the first upper frame (11) and the second upper frame (12) are pulled, which drives the unfolding of the first lower frame (21) and the second lower frame (22). Since the third lower frame (23) is arranged between the first lower frame (21) and the second lower frame (22), the lower frame (2) is folded into three sections. Of course, in other embodiments, the third lower frame (23) can also consist of two or more sections, with a smoother transition at the fold. The third lower frame (23) creates more space between the first lower frame (21) and the second lower frame (22).Firstly, the first lower frame (21), the second lower frame (22), and the third lower frame (23) are arranged in parallel in a U-shape after folding. Compared to the two-part V-shaped frame, they take up less space. Secondly, the head and fabric cover are less susceptible to pressure damage and are flatter after the sleeping basket is folded. Of course, in other designs, a 4D upper frame can also be arranged between the first upper frame (11) and the second upper frame (12) to achieve a better effect after folding.

[0030] As a preferred embodiment, the foldable sleeping basket also includes a locking mechanism (4). The locking mechanism (4) serves to lock the first foldable part (13) to prevent the first upper frame (11) and the second upper frame (12), as well as the first lower frame (21) and the second lower frame (22) from being folded.

[0031] In this structure, when the sleeping basket is unfolded for use, the locking mechanism locks the first foldable part (13), and the first upper frame (11) and the second lower frame (12) cannot be folded. Since the first lower frame (21) and the second lower frame (22) are connected to the first upper frame (11) and the second upper frame (12) via the first foldable part (31) and the second foldable part (32), when the first upper frame (11) and the second upper frame (12) cannot be folded, the first lower frame (21) and the second lower frame (22) cannot be folded either. Compared with using a state where the sleeping basket is held depending on the fixing amount of the pivot point, the structure is safer and more stable.Of course, in other embodiments, the locking mechanism (4) can also be arranged on the third lower frame (23) to lock the third lower frame (23), or can be arranged on both the first foldable part (13) and the third lower frame (23) to achieve the above-mentioned effect.

[0032] As a preferred embodiment, an unlocking mechanism (5) is arranged on the upper frame (1), and the unlocking mechanism (5) can unlock the locking mechanism (4).

[0033] In this concept, a release mechanism (5) is mounted on the upper frame (1). Compared to manually unlocking the locking mechanism (4) on both sides, even when removing the fabric cover of the sleeping basket to operate the first folding part (31) and the second folding part (32), this process is more convenient and easier.

[0034] As a preferred embodiment, the first foldable part (31) comprises a first connecting rod (311) and a first support rod (312), wherein one end of the first support rod (312) can be rotated and connected to the first upper frame (11) and the other end of the first support rod (312) can be rotated and connected to the third lower frame (23).The first connecting rod (311) comprises a first partial rod (3111), a second partial rod (3112), and a third partial rod (3113), wherein the middle part of the third partial rod (3113) can be rotated and connected to the middle part of the first support rod (312), one end of the third partial rod (3113) can be rotated and connected to one end of the first partial rod (3111), the other end of the third partial rod (3113) can be rotated and connected to one end of the second partial rod (3112), the other end of the first partial rod (3111) can be rotated and connected to the part of the first upper frame (11) near the first bendable part (13), and the other end of the second partial rod (3112) can be rotated and connected to the part of the first lower frame (21) that is remote from the third lower frame (23).The second foldable part (32) comprises a second connecting rod (321), wherein one end of the second connecting rod (321) can be rotated and connected to the second upper frame (12) and the other end of the second connecting rod (321) can be rotated and connected to the second lower frame (22).

[0035] In this embodiment, the first upper frame (11) is connected to the second upper frame (12) via the first foldable part (13) and can also be folded upward via the pivot point at the connection with the first foldable part (13). The first lower frame (21) and the second lower frame (22) can each be folded towards each other via the pivot point at the connection with the third lower frame (23). In addition, the first foldable part (31) is arranged between the first upper frame (11) and the first lower frame (21), and the second foldable part (32) is arranged between the second upper frame (12) and the second lower frame (22). When the first upper frame (11) is folded upward, the second lower frame (22) is driven to fold upward.At the same time, the second upper frame (12) exerts a downward force on the end of the first upper frame (11) near the first bendable part (13) to move the first sub-rod (3111) downward via the first bendable part (13). In addition, the middle part of the third sub-rod (3113) can be rotated and connected to the middle part of the first support rod (312). As the first sub-rod (3111) moves downward, the third sub-rod (3113) is driven to rotate at the connection between the third sub-rod (3113) and the first support rod (312). Since the third sub-rod (3113) can be rotated and connected to the second sub-rod (3112), the first sub-rod (3111) can be rotated and connected to the first upper frame (11), and the second sub-rod (3112) can be rotated and connected to the first lower frame (21).When the third sub-rod (3113) rotates, the second sub-rod (3112) is pulled to fold the first lower frame (21) upward. Furthermore, the first support rod (312) is fixed and connected to the third lower frame (23). When folded, the first upper frame (11), the second upper frame (12), the first lower frame (21), and the second lower frame (22) have the same inclination angle with the first support rod (312), so the sleeping basket can be tilted in one direction and fitted into the vehicle frame for convenient storage.

[0036] As a preferred embodiment, the second foldable part (32) also comprises a third connecting rod (322), wherein one end of the third connecting rod (322) can be rotated and connected to the second upper frame (12) and the other end of the third connecting rod (322) can be rotated and connected to the connection between the second lower frame (22) and the third lower frame (32).

[0037] In this embodiment, the other end of the third connecting rod (322) can be rotated and connected to the joint between the second lower frame (22) and the third lower frame (23). The joints between the second foldable part (32) and the upper (1) / lower frame (2) are evenly distributed. Therefore, the structure is more stable and reliable, and less prone to deformation.

[0038] As in the Fig. 5 and Fig. 6, this embodiment also provides a stroller incorporating the foldable sleeping basket. Embodiment 2

[0039] As in the Fig. As shown in Figures 7 to 9, Embodiment 2 of this utility model provides a foldable sleeping basket, wherein the first foldable part (31) comprises a first connecting rod (311), one end of the first connecting rod (311) can be rotated and connected to the first upper frame (11) and the other end of the first connecting rod (311) can be rotated and connected to the first lower frame (21).

[0040] In this embodiment, one end of the first connecting rod (311) is connected to the central part of the first upper frame (11). The upper frame (1) and the lower frame (2) are evenly loaded and less prone to deformation. The first foldable part (31) is connected to the folding movement of the first upper frame (11) and the first lower frame (21) via the first connecting rod (311) arranged between the first upper frame (11) and the first lower frame (21), enabling a simple structure and lower production costs.

[0041] As a preferred embodiment, the first foldable part (31) also comprises a second connecting rod (321), wherein one end of the second connecting rod (321) can be rotated and connected to the first upper frame (11), and the other end of the second connecting rod (321) can be rotated and connected to the connection between the first lower frame (21) and the third lower frame (23).

[0042] In this concept, the other end of the second connecting rod (321) can be rotated and connected to the joint between the first lower frame (21) and the third lower frame (23). The joints between the first foldable part (31) and the upper (1) / lower frame (2) are evenly distributed. Therefore, the structure is more stable and reliable, and less prone to deformation.

[0043] As a preferred embodiment, the second foldable part (32) is arranged symmetrically to the first foldable part (31).

[0044] In this concept, the second foldable part (32) is arranged symmetrically with the first foldable part (31). The sleeping basket is simple in design and inexpensive to manufacture.

[0045] This embodiment also provides a stroller that also includes a foldable sleeping basket.

[0046] In this concept, for the sleeping basket on the stroller, the first upper frame (11) is connected to the second upper frame (12) via the first foldable part (13) and can also be folded upwards via the pivot point at the connection with the first foldable part (13). The first lower frame (21) and the second lower frame (22) can each be folded towards each other via the pivot point at the connection with the third lower frame (23). In addition, the first foldable part (31) is arranged between the first upper frame (11) and the first lower frame (21), and the second foldable part (32) is arranged between the second upper frame (12) and the second lower frame (22).

[0047] When the first upper frame (11) is folded upwards over the pivot point at the connection with the first foldable part (13), the first foldable part (31) drives the first lower frame (21) to fold upwards over the pivot point at the connection with the third lower frame (23). Similarly, when the second upper frame (12) is folded upwards, the second lower frame (22) is driven to fold downwards to reduce the space required by the sleeping basket for easy storage. When the foldable sleeping basket needs to be unfolded for use, the first upper frame (11) and the second upper frame (12) are pulled, causing the first lower frame (21) and the second lower frame (22) to unfold. Since the third lower frame (23) is arranged between the first lower frame (21) and the second lower frame (22), the lower frame (2) is folded into three sections.Of course, in other embodiments, the third lower frame (23) can also have a structure with two or more sections, with a smoother transition at the fold. The third lower frame (23) creates more space between the first lower frame (21) and the second lower frame (22). Firstly, the first lower frame (21), the second lower frame (22), and the third lower frame (23) assume a U-shape after folding. Compared to the two-part, V-shaped frame, less space is taken up. Secondly, the head and the fabric cover are less susceptible to damage from pressure and are flatter after the sleeping basket is folded. Embodiment 3

[0048] As in the Fig.As shown in Figures 10 to 12, Embodiment 3 of this utility model provides a foldable sleeping basket, wherein the first foldable part (31) comprises a first connecting rod (311) and a second connecting rod (321), one end of the second connecting rod (321) can be rotated and connected to the first upper frame (11) and the other end of the second connecting rod (321) can be rotated and connected to the connection between the first lower frame (21) and the third lower frame (23).The first connecting rod (311) comprises a first partial rod (3111), a second partial rod (3112), and a third partial rod (3113), wherein the middle part of the third partial rod (3113) can be rotated and connected to the middle part of the second connecting rod (321), one end of the third partial rod (3113) can be rotated and connected to one end of the first partial rod (3111), the other end of the third partial rod (3113) can be rotated and connected to one end of the second partial rod (3112), the other end of the first partial rod (3111) can be rotated and connected to the part of the first upper frame (11) near the first bendable part (13), and the other end of the second partial rod (3112) can be rotated and connected to the part of the first lower frame (21) that is remote from the third lower frame (23).

[0049] In this concept, both ends of the second connecting rod (321) can be rotated and connected to the first upper frame (11) and the connection between the first lower frame (21) and the third lower frame (23). When the first upper frame (11) is folded upward, the second connecting rod (321) is driven to rotate about the pivot point at the connection between the first lower frame (21) and the third lower frame (23). In addition, the middle part of the third sub-rod (3113) can be rotated and connected to the middle part of the second connecting rod (321). When the second connecting rod (321) rotates, the third sub-rod (3113) is driven to rotate at the connection between the third sub-rod (3113) and the second connecting rod (321).Since the third partial rod (3113) can be rotated and connected to the first partial rod (3111) and the second partial rod (3112), the first partial rod (3111) can be rotated and connected to the first upper frame (11), and the second partial rod (3112) can be rotated and connected to the first lower frame (21). When the third partial rod (3113) rotates, the second partial rod (3112) is pulled to drive the first lower frame (21) to fold it upward. In the structure, the first foldable part (31) is in an X-shape, with uniform load at the connections with the first upper frame (11) and the first lower frame (21). The structure is more stable and reliable.

[0050] As a preferred embodiment, the second foldable part (32) is arranged symmetrically with the first foldable part (31).

[0051] The second foldable part (32) is arranged symmetrically with the first foldable part (31). The sleeping basket is simple in construction and inexpensive to manufacture. Of course, in other embodiments, the first foldable part (31) can use the method in Embodiment 2 and the second foldable part (32) can use the method in Embodiment 3 to form an asymmetric arrangement.

[0052] This embodiment also provides a stroller including the above foldable sleeping basket.
