Description

Technical Field

[0001] This invention relates to the field of infant and toddler carriers, and in particular to a sleeping box. Prior Technology

[0002] With increased family activities and travel frequency, the carrying and safety of infants and toddlers have become major concerns for parents. In response, various infant carriers, such as sleeping boxes, have emerged on the market, designed to provide convenience for parents while ensuring the safety and comfort of their children. These carriers are typically designed with foldable features to reduce their size when not in use, making them easy to carry and store.

[0003] However, while current folding mechanisms offer some convenience, most employ simple mechanical structures that require only a certain amount of pulling or pressure to unlock. This design poses a significant safety hazard, as accidental unlocking by parents or infants could result in injury to the child.

[0004] Therefore, Canada has introduced regulations for sleeping boxes, requiring that the folding mechanism of the sleeping box must be unlocked by two actions when folding, rather than by a single action. Summary of the Invention

[0005] Therefore, it is necessary to provide a sleeping box that is easy to operate and has high reliability and safety.

[0006] This application provides a sleeping box, comprising: a frame; a base frame; a folding mechanism connected between the frame and the base frame, the folding mechanism having an unfolded state and a folded state; a locking member movably disposed on the folding mechanism and having a locked position and an unlocked position, wherein when the locking member is in the locked position, the locking member locks the folding mechanism in the unfolded state, and when the locking member is in the unlocked position, the locking member releases the locking of the folding mechanism in the unfolded state, allowing the folding mechanism to switch from the unfolded state to the folded state; and a release mechanism, comprising a first operating member and a second operating member, the first operating member being movably disposed on the folding mechanism and having a locked position and an unlocked position, and the first... An operating member drives the locking member to move. When the first operating member is in the locked position, the locking member is in the locked position. When the first operating member is in the unlocked position, the locking member is in the unlocked position. The second operating member is movably disposed on the folding mechanism and has a first position and a second position. When the second operating member is in the first position, the first operating member is in the locked position, and the second operating member is located on the movement path of the first operating member to restrict the first operating member from moving from the locked position to the unlocked position. When the second operating member is in the second position, the second operating member deviates from the movement path of the first operating member to allow the first operating member to move from the locked position to the unlocked position.

[0007] In one embodiment, the first operating member is provided with a pushing part, and when the second operating member is in the first position, the pushing part abuts against the second operating member.

[0008] In one embodiment, the second operating member is a columnar structure that extends along the moving path of the second operating member, and the pushing portion is a notch that can be adapted to the outer peripheral wall of the columnar structure.

[0009] In one embodiment, when the folding mechanism is in the folded state, the first operating member presses against the second operating member to keep the second operating member in the second position.

[0010] In one embodiment, the movement path of the second actuation element intersects with the movement path of the first actuation element; and / or, the second actuation element is located on the outer periphery of the first actuation element and is independent of the first actuation element.

[0011] In one embodiment, the first operating member has an operating surface adapted to be operated, wherein when the first operating member is in the locked position and the second operating member is in the first position, the operating surface is located behind the second operating member along the direction of movement of the first operating member from the locked position to the unlocked position.

[0012] In one embodiment, the first operating member includes a pressing portion that can press against the second operating member to hold the second operating member in the second position, wherein the sum of the size of the second operating member along the movement path of the first operating member and the size of the pressing portion along the movement path of the first operating member is greater than the distance the first operating member moves from the locked position to the unlocked position.

[0013] In one embodiment, the folding mechanism includes: a first support member connected to the frame; and a second support member connected to the base frame and pivotally connected to the first support member. One of the first and second support members is provided with a locking part. A locking member is movably disposed on the other of the first and second support members. When the folding mechanism is in the unfolded state and the locking member is in the locked position, the locking member locks with the locking part to restrict the first support member from pivoting relative to the second support member. When the folding mechanism is in the unfolded state and the locking member is in the unlocked position, the locking member releases the locking part to allow the first support member to pivot relative to the second support member.

[0014] In one embodiment, the first operating element and the second operating element are jointly disposed on the first support or the second support having the locking element.

[0015] In one embodiment, the locking member has a locking protrusion and the locking part has a concave structure; when the locking protrusion extends into the locking part to lock and engage, the locking member locks with the locking part; when the locking protrusion retracts from the locking part to release the lock, the locking member releases the lock on the locking part.

[0016] In one embodiment, the sleeping box further includes a first reset member, which provides an elastic restoring force biased towards the locked position for the locking member. The first or second support member having the locking portion has a guide surface, which is located on the outer periphery of the locking portion and is arc-shaped. When the folding mechanism is in the folded state, the locking protrusion abuts against the guide surface due to the elastic restoring force applied to the locking member by the first reset member, so that the locking member is located between the locked position and the unlocked position. The first operating member presses against the second operating member, so that the second operating member is held in the second position.

[0017] In one embodiment, the release mechanism further includes a second reset member, which provides the second operating member with an elastic restoring force biased toward the first position. Simple Explanation of the Diagram

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] Figure 1 shows a perspective view of a sleeping box 1000 provided according to an embodiment of the present invention, and Figures 2 and 3 show perspective views of the sleeping box 1000 provided according to another perspective view according to an embodiment of the present invention. The sleeping box 1000 has an extended state and a folded state. When the sleeping box 1000 is in the extended state, the infant can lie down and rest inside the sleeping box 1000, while when the sleeping box 1000 is in the folded state, the volume of the sleeping box 1000 is reduced for storage or transportation.

[0021] Referring to Figures 1 to 4, in one embodiment, the sleeping box 1000 may include, for example, a frame 100, a base frame 200, a folding mechanism 300, a locking element 600, and a release mechanism 400. The folding mechanism 300 is connected between the frame 100 and the base frame 200, and has an unfolded state and a folded state. As shown in Figures 1 to 3, when the sleeping box 1000 is in the unfolded state, the folding mechanism 300 is in the unfolded state; as shown in Figure 4, when the sleeping box 1000 is in the folded state, the folding mechanism 300 is in the folded state; or, it can be considered that when the folding mechanism 300 is in the unfolded state, the sleeping box 1000 is correspondingly in the unfolded state, and when the folding mechanism 300 is in the folded state, the sleeping box 1000 is correspondingly in the folded state. To prevent infants from being pinched when lying in the sleeping box 1000 due to its folding mechanism, as shown in Figures 5 to 8, a locking element 600 is provided on the folding mechanism 300. Specifically, the locking element 600 is movably mounted on the folding mechanism 300 and has a locked position and an unlocked position. As shown in Figure 7, when the locking element 600 is in the locked position, it can lock the folding mechanism 300 in its unfolded state; in other words, the unfolded folding mechanism 300 will be locked by the locking element 600, which can keep the folding mechanism 300 in its unfolded state. That is, the locking element 600 can prevent the unfolded folding mechanism 300 from changing to the folded state, thereby keeping the sleeping box 1000 in its unfolded state. As shown in Figure 8, when the locking member 600 is in the unlocked position, it can release the lock on the unfolded folding mechanism 300, allowing the folding mechanism 300 to switch from the unfolded state to the folded state, and thus allowing the sleeping box 1000 to switch to the folded state. In one embodiment, referring to Figures 2, 3, and 6, the release mechanism 400 works in conjunction with the locking member 600. The release mechanism 400 can be used to control the locking member 600 to switch from the locked position to the unlocked position, thus releasing the lock on the unfolded folding mechanism 300 and allowing the folding mechanism 300 to switch from the unfolded state to the folded state. Specifically, the release mechanism 400 may include a first operating member 410 and a second operating member 420. The first operating element 410 is movably disposed in the folding mechanism 300 and has a locked position (referring to Figures 2 and 7) and an unlocked position (referring to Figures 3 and 8). The first operating element 410 is driven to cooperate with the locking element 600; in other words, the first operating element 410 can drive the locking element 600 to move. Specifically, when the first operating element 410 is in the locked position, the locking element 600 is in the locked position; when the first operating element 410 is in the unlocked position, the locking element 600 is in the unlocked position. Therefore, the user can control the position of the locking element 600 by operating the first operating element 410, thereby controlling the folding mechanism 300 to switch between the unfolded and folded states.To improve the reliability and safety of the sleeping box 1000 and prevent accidental folding of the folding mechanism 300 due to accidental contact with the first operating element 410 by infants or users, a second operating element 420 is specifically provided. More specifically, the second operating element 420 is movably disposed in the folding mechanism 300 and has a first position (see Figure 2) and a second position (see Figure 3). When the second operating element 420 is in the first position, the first operating element 410 is in the locked position. At this time, the second operating element 420 is located on the movement path of the first operating element 410 to restrict the first operating element 410 from moving from the locked position to the unlocked position, thereby preventing the locking element 600 from switching from the locked position to the unlocked position. When the second operating element 420 is in the second position, the second operating element 420 deviates from the movement path of the first operating element 410 to allow the first operating element 410 to move from the locked position to the unlocked position, thereby allowing the locking element 600 to switch from the locked position to the unlocked position. Therefore, when a user needs to fold the sleeping box 1000, the user must first operate the second operating component 420 to remove it from the movement path of the first operating component 410, thus releasing the restriction on the first operating component 410. Afterward, the first operating component 410 can operate normally to drive the locking component 600 to the unlocked position, thereby releasing the lock on the folding mechanism 300 and ultimately allowing the folding mechanism 300 to switch to the folded state to fold the sleeping box 1000. This two-step unlocking design significantly improves the safety and reliability of the sleeping box 1000 during use, effectively preventing accidental folding incidents caused by accidental activation and ensuring the safety of infants and young children.

[0022] In the aforementioned sleeping box 1000, a folding mechanism 300 is connected between the frame 100 and the base frame 200. Since the folding mechanism 300 has two modes—an unfolded state and a folded state—it can correspondingly move the frame 100 and the base frame 200 closer together or further apart when switching between these two states, thus enabling the sleeping box 1000 to flexibly change between an unfolded and folded state. Specifically, when the sleeping box 1000 needs to be used, simply adjust the folding mechanism 300 to the unfolded state, and the sleeping box 1000 will automatically be in the unfolded state; when not in use, adjusting the folding mechanism 300 to the folded state allows the sleeping box 1000 to be folded up, saving space.

[0023] It should be noted that in the aforementioned sleeping box 1000, the frame 100 is located above the base frame 200 and is roughly parallel to it. When the folding mechanism 300 is in the unfolded state, a carrying space 101 is formed between the frame 100, the folding mechanism 300, and the base frame 200 (see Figures 1 and 2). At this time, the sleeping box 1000 can be used normally, and infants can lie down and rest in the carrying space 101. When the folding mechanism 300 is in the folded state, the frame 100 and the base frame 200 are close together. At this time, the sleeping box 1000 is reduced in size and can be roughly flattened for storage or transportation.

[0024] Referring to Figures 1 and 2, in one embodiment, the frame 100 can be formed into a ring structure by tubular components. The base frame 200 can also be formed into a ring structure by tubular components; alternatively, the base frame 200 can be a plate structure, thus forming the bottom wall of the load-bearing space 101, which can stably support infants and young children. The shape of the base frame 200 is approximately the same as that of the frame 100. For example, both the base frame 200 and the frame 100 can be roughly rectangular, circular, or triangular, etc., without specific limitations. Specifically, in the illustrated embodiment, the base frame 200 is a roughly rectangular plate structure, and the frame 100 is a roughly rectangular ring structure. The frame 100 includes two opposing side rails 110 and two opposing transverse rails 120 connected between the two side rails 110. The side rails 110 extend approximately along a first direction F1, and the transverse rails 120 extend approximately along a second direction F2, with the first direction F1 and the second direction F2 being approximately perpendicular. Specifically, the first direction F1 can be considered as the front-to-back direction of the sleeping box 1000, and the second direction F2 can be considered as the left-to-right direction of the sleeping box 1000. More specifically, the two transverse rails 120 are respectively located at both ends of the side rails 110. In other words, the adjacent side rails 110 and transverse rails 120 are connected by their corresponding ends.

[0025] It should be noted that, unless otherwise explicitly specified and limited, the directional terms such as "front," "rear," "left," and "right" related to the sleeping box 1000 in various embodiments of the present invention are schematically indicated by arrows P and B for "front" and "rear," and by arrows L and R for "left" and "right." These directional terms are only used to make the description of the embodiments of the present invention clearer and are not intended to unduly limit the scope of protection of the present invention.

[0026] In one embodiment, the sleeping box 1000 includes at least two folding mechanisms 300, for example, there are two, three, four or more folding mechanisms 300. When the sleeping box 1000 includes two folding mechanisms 300, in order to improve the stability of the sleeping box 1000 structure, the two folding mechanisms 300 are arranged at intervals along the front-back direction or left-right direction of the sleeping box 1000. For example, the two folding mechanisms 300 are respectively connected between the two side rails 110 and the base frame 200; or, the two folding mechanisms 300 are respectively connected between the two transverse rails 120 and the base frame 200, without specific limitations. Specifically, in the illustrated embodiment, the sleeping box 1000 includes four folding mechanisms 300, with one folding mechanism 300 connected to each of the two side rails 110 and the two transverse rails 120.

[0027] Referring to Figures 1 and 2, in one embodiment, the sleeping box 1000 also includes a handle 500, which is pivotally connected to the frame 100 to allow the user to carry the sleeping box 1000. Specifically, the two ends of the handle 500 can be pivotally connected to two side rails 110 respectively; of course, in other embodiments, the two ends of the handle 500 can also be pivotally connected to two transverse rails 120 respectively, without specific limitations.

[0028] In one embodiment, a barrier (not shown) may be connected between the base frame 200 and the enclosure 100, forming a sidewall of the carrying space 101. The barrier may be made of a flexible material, folding down when the folding mechanism 300 folds down and unfolding when the folding mechanism 300 unfolds to form a sidewall of the carrying space 101. Optionally, the enclosure 100 and / or the base frame 200 may be covered with a fabric cover (not shown), which not only conceals the exposed enclosure 100 and base frame 200, providing a good decorative effect, but also improves the comfort of the infant lying in the sleeping box 1000.

[0029] Referring to Figures 1 to 4, in one embodiment, the folding mechanism 300 includes a first support member 310 and a second support member 320 pivotally connected to each other. Specifically, the end of the first support member 310 away from the second support member 320 is connected to the frame 100, and the end of the second support member 320 away from the first support member 310 is connected to the base frame 200. More specifically, the end of the first support member 310 away from the second support member 320 is rotatably connected to the frame 100, and the end of the second support member 320 away from the first support member 310 is rotatably connected to the base frame 200. Therefore, when the first support member 310 pivots relative to the second support member 320 to move closer to the second support member 320 (switching from Figure 3 to Figure 4), it can be considered that when the folding mechanism 300 switches from an unfolded state to a folded state, the first support member 310 will drive the frame 100 to gradually move closer to the base frame 200, so that the sleeping box 1000 switches to a folded state. When the first support member 310 pivots relative to the second support member 320 to move away from the second support member 320 (switching from Figure 4 to Figure 3), it can be regarded as the folding mechanism 300 switching from the folded state to the unfolded state. The first support member 310 will push the frame 100 to gradually move away from the base frame 200 so that the sleeping box 1000 switches to the unfolded state.

[0030] It should be noted that, as shown in Figures 1 to 3, when the folding mechanism 300 is in the unfolded state, the first support member 310 and the second support member 320 extend approximately along the same straight line, and the included angle between them can be approximately 180°. When the folding mechanism 300 is in the folded state, the included angle between the first support member 310 and the second support member 320 can approach 0°, or the included angle can be greater than 0°, such as 10°, 20°, etc. It should be emphasized that the size of the included angle between the first support member 310 and the second support member 320 when the folding mechanism 300 is in the folded state is not specifically limited here; in other words, for example, we can consider the state of the folding mechanism 300 as the folded state when the included angle between the first support member 310 and the second support member 320 is 0°, 5°, 10°, or 15°, etc. It should also be noted that the state of the folding mechanism 300 shown in Figure 4 of this application can be regarded as being in a folded state; of course, it can also be regarded as being in any transitional state between the unfolded state and the folded state.

[0031] Referring to Figures 5 to 8, in one embodiment, the locking member 600 is movably disposed on one of the first support member 310 and the second support member 320. Correspondingly, the other of the first support member 310 and the second support member 320 is provided with a locking part 323. For example, the locking member 600 is movably disposed on the first support member 310, and the locking part 323 is disposed on the second support member 320. Alternatively, the locking member 600 is movably disposed on the second support member 320, and the locking part 323 is disposed on the first support member 310. The locking member 600 is used to lock into the locking part 323, thereby restricting the pivoting of the first support member 310 relative to the second support member 320. Specifically, when the folding mechanism 300 is in the unfolded state and the locking member 600 is in the locked position, the locking member 600 is locked with the locking part 323 (see Figure 7), and the first support member 310 is restricted from pivoting relative to the second support member 320, thereby maintaining the folding mechanism 300 in the unfolded state. When the folding mechanism 300 is in the unfolded state and the locking member 600 is in the unlocked position, the locking member 600 releases the locking of the mating lock part 323 (see Figure 8), and the first support member 310 is allowed to pivot relative to the second support member 320 to allow the folding mechanism 300 to switch from the unfolded state to the folded state.

[0032] Referring again to Figures 5 to 8, in one embodiment, both the first support member 310 and the second support member 320 can generally be in the form of a strip-shaped cylindrical or plate-like structure. The first support member 310 includes a first connecting portion 311 and a first pivot portion 312 connected together, and the second support member 320 includes a second connecting portion 321 and a second pivot portion 322 connected together. The first pivot portion 312 and the second pivot portion 322 are pivotally connected via a first pivot axis (not shown in the figures); the first connecting portion 311 is rotatably connected to the frame 100, and the second connecting portion 321 is rotatably connected to the base frame 200. This allows the first support member 310 to pivot relative to the second support member 320 about the first pivot axis, thereby causing the frame 100 and the base frame 200 to move closer or further apart.

[0033] It should be noted that the rotatable connection between the first connecting part 311 and the frame 100 includes two implementation methods: first, the first connecting part 311 is directly rotatably connected to the frame 100; second, the first connecting part 311 is indirectly rotatably connected to the frame 100. Specifically, in the illustrated embodiment, as shown in Figures 5 and 6, a rotating ring 130 is fitted on the frame 100. The rotating ring 130 can rotate relative to the frame 100. The first connecting part 311 is fixedly connected to the rotating ring 130, thus allowing the first connecting part 311 to rotate relative to the frame 100. Similarly, the rotatable connection between the second connecting part 321 and the base frame 200 also includes two implementation methods: first, the second connecting part 321 is rotatably connected to the base frame 200; second, the second connecting part 321 is indirectly rotatably connected to the base frame 200. Specifically, in the illustrated embodiment, as shown in Figures 5 and 6, a rotating connection portion 210 is provided on the base frame 200, and a second connection portion 321 is pivotally connected to the rotating connection portion 210 via a second pivot shaft (not shown in the figure), so that the second connection portion 321 can rotate relative to the base frame 200.

[0034] In the illustrated embodiment, as shown in Figures 6 to 8, the locking member 600 is movably disposed on the first support member 310 and has a locking position and an unlocking position on the first support member 310, while the second support member 320 is provided with a locking part 323. Specifically, the first support member 310 has an inner cavity 313, in which the locking member 600 is movably disposed. Furthermore, the first pivot portion 312 of the first support member 310 has a through hole 314, which communicates with the inner cavity 313. Specifically, the locking part 323 is disposed on the second pivot portion 322 of the second support member 320, and can be a concave structure (such as a groove or hole structure). The locking member 600 has a locking protrusion 610, which moves with the locking member 600 and can pass through the through hole 314 to extend into the locking part 323. Specifically, when the locking member 600 moves to allow the locking protrusion 610 to pass through the through hole 314 and extend into the locking part 323 for locking engagement (see Figure 7), the locking member 600 locks with the locking part 323. This locks the first support member 310 and the second support member 320 together, effectively restricting the first support member 310 from pivoting relative to the second support member 320 about the first pivot axis. At this time, the folding mechanism 300 is restricted from switching from the unfolded state to the folded state; in other words, the folding mechanism 300 can remain in the unfolded state. It should be noted that the aforementioned locking position refers to the position of the locking member 600 within the inner cavity 313 when the locking protrusion 610 is extended into the locking part 323. When the locking member 600 moves to disengage the locking protrusion 610 from the locking part 323 to release the lock (see Figure 8), the locking member 600 releases the lock on the locking part 323. Thus, the lock between the first support member 310 and the second support member 320 can be considered released, equivalent to the first support member 310 being allowed to pivot about the first pivot axis relative to the second support member 320. At this time, the folding mechanism 300 can switch from the unfolded state to the folded state. It should be noted that the unlocked position mentioned above refers to the position of the locking member 600 in the inner cavity 313 when the locking protrusion 610 disengages from the locking part 323.

[0035] To facilitate user control of the locking element 600 from the locked position to the unlocked position, thereby switching the folding mechanism 300 to the folded state, the following design is made. Referring again to Figures 2 and 3, in one embodiment, the first operating element 410 is movably disposed on the first support element 310 and has a locked position (see Figure 2) and an unlocked position (see Figure 3) on the first support element 310. The second operating element 420 is movably disposed on the first support element 310 and has a first position (see Figure 2) and a second position (see Figure 3) on the first support element 310. In other words, the first operating element 410 and the second operating element 420 are jointly disposed on the first support element 310. Therefore, the user can drive the first operating element 410 and the second operating element 420 to move separately by one hand (the operation process is described below), thus improving the convenience of operating the sleeping box 1000. It should be noted that in other embodiments, when the locking element 600 is disposed on the second support element 320, the first operating element 410 and the second operating element 420 are adapted to be jointly disposed on the second support element 320.

[0036] In the illustrated embodiment, the movement path of the second operating member 420 intersects with the movement path of the first operating member 410. Specifically, their movement paths are perpendicular. More specifically, the movement path of the first operating member 410 is approximately parallel to the length extension direction of the first support member 310, and the movement path of the second operating member 420 is approximately perpendicular to the length extension direction of the first support member 310.

[0037] Referring to Figures 6 and 7, in one embodiment, the first support member 310 is provided with a guide hole 315, which communicates with the inner cavity 313. Specifically, the guide hole 315 extends along the moving direction of the locking member 600 and the first operating member 410. The first operating member 410 has a gripping part 411 and a driving part 412 connected together, wherein the driving part 412 is used to pass through the guide hole 315 and connect to the locking member 600, and the gripping part 411 protrudes outward from the first support member 310 to facilitate user gripping. The user can grip the gripping part 411 and drive the locking member 600 to move by pushing or pulling the gripping part 411.

[0038] Referring to Figures 6 to 8, in one embodiment, the folding mechanism 300 further includes a first reset member 700. This first reset member 700 can be, for example, an elastic element such as a spring or sheet, and is mainly used to provide an elastic restoring force biased towards the locking position for the locking member 600. Specifically, the first reset member 700 is mainly used to ensure that the locking protrusion 610 has a constant tendency to insert into the locking part 323, thus keeping the locking member 600 locked to the folding mechanism 300. In the illustrated embodiment, the first reset member 700 is a compression spring, which is disposed in the inner cavity 313 of the first support member 310. One end of the compression spring abuts against the cavity wall of the inner cavity 313, and the other end abuts against the locking member 600. It is used to keep the locking member 600 in the locked position, thereby improving the reliability and stability of the locking protrusion 610 extending into the locking part 323, and thus improving the reliability of the folding mechanism 300 when it is in the unfolded state. Furthermore, under the action of the first reset member 700, the locking member 600 can automatically reset to the locked position.

[0039] In one embodiment, as shown in FIG6, the release mechanism 400 further includes a second reset member 430. This second reset member 430 can be, for example, an elastic element such as a spring or sheet, and is mainly used to provide an elastic restoring force biased towards the first position for the second operating member 420, so that the second operating member 420 remains in the first position. In this way, the second operating member 420 can restrict the movement of the first operating member 410, preventing users or infants from accidentally touching the first operating member 410, thus improving the reliability and safety of the sleeping box 1000. Specifically, in the illustrated embodiment, the second reset member 430 is a compression spring, which abuts against the second operating member 420 and the first support member 310, and is used to hold the second operating member 420 in the first position.

[0040] Referring to Figures 2, 3, and 6, in one embodiment, the first operating member 410 is provided with a pushing portion 413, which is adapted to abut against the second operating member 420. Specifically, when the second operating member 420 is in the first position, the pushing portion 413 abuts against the second operating member 420, thus restricting the movement of the first operating member 410 and keeping it in the locked position. This design ensures that without any operation (such as pressing) on ​​the second operating member 420, the first operating member 410 will not move to the unlocked position due to accidental contact, thereby avoiding the risk of the folding mechanism 300 accidentally unlocking and switching to the folded state.

[0041] Referring to Figure 6, in one embodiment, the second operating member 420 is a columnar structure, such as a cylinder, triangular prism, or other polygonal prism, and this columnar structure extends along the moving path of the second operating member 420. The pushing portion 413 is a notch that can adapt to the outer peripheral wall of the columnar structure. Specifically, in the illustrated embodiment, the second operating member 420 is cylindrical, but since its length is relatively short, the second operating member 420 can also be regarded as a disk, and the outer peripheral wall of the second operating member 420 is a circular outer wall. Correspondingly, the sidewall of the notch is an arc-shaped structure, so that when the second operating member 420 abuts against the pushing portion 413, the circular outer wall of the second operating member 420 can fit against the sidewall of the notch.

[0042] It should be noted that, in the illustrated embodiment, as shown in Figures 1 and 2, the pushing portion 413 is a recess formed on the circumferential sidewall of the first operating member 410. When the second operating member 420 is in the first position, the second operating member 420 is located on the outer periphery of the first operating member 410 and abuts against the pushing portion 413, and the second operating member 420 is independent of the first operating member 410. This facilitates the user's one-handed operation of the second operating member 420 and the first operating member 410, improving the convenience of folding the sleeping box 1000.

[0043] Referring to Figures 2 and 3, in one embodiment, when the folding mechanism 300 is in the folded state, the first operating member 410 presses against the second operating member 420 to hold the second operating member 420 in the second position. Specifically, the first operating member 410 further includes a pressing portion 414, which can press against the second operating member 420 to hold the second operating member 420 in the second position. Specifically, the pressing portion 414 is located on the side of the first operating member 410 closer to the second operating member 420. More specifically, the pushing portion 413 is a notch formed in the side wall of the pressing portion 414; in other words, the pushing portion 413 can also be regarded as a side wall of the pressing portion 414. In the illustrated embodiment, the sum of the dimension of the second operating member 420 along the movement path of the first operating member 410 and the dimension of the pressing portion 414 along the movement path of the first operating member 410 is greater than the distance the first operating member 410 moves from the locked position to the unlocked position. Specifically, in the illustrated embodiment, referring to Figures 2 and 3, taking the unfolded state of the folding mechanism 300 as an example, the moving direction of the first operating member 410 is referred to as the third direction F3; the direction perpendicular to the moving path of the first operating member 410 is referred to as the fourth direction F4. In the illustrated embodiment, the second operating member 420 is a disk, and its dimension in the third direction F3 is referred to as the first height, and the value of the first height varies along the fourth direction F4; similarly, the dimension of the pressing part 414 in the third direction F3 is referred to as the second height, and since the pressing part 414 has an irregular shape, the value of the second height also varies along the fourth direction F4. More specifically, in the illustrated embodiment, the line parallel to the third direction F3 and passing through the center of the second operating member 420 is called the virtual reference line S. Specifically, the first end of the pressing part 414 along the fourth direction F4 coincides with the virtual reference line S. Therefore, with the virtual reference line S as a reference, the size of the second operating member 420 along the moving path of the first operating member 410 can be regarded as the first height of the second operating member 420 along the virtual reference line S, that is, the diameter of the second operating member 420, which can be represented by D. The size of the pressing part 414 along the moving path of the first operating member 410 is regarded as the size of the pressing part 414 along the virtual reference line S. The second height, which can be represented by H, is the distance L that the first operating member 410 moves from the locked position to the unlocked position. Thus, D+H>L. Therefore, when the first operating member 410 is in the unlocked position, it can ensure that the first operating member 410 presses against the second operating member 420 so that the second operating member 420 can be kept in the second position. This prevents the second operating member 420 from being disengaged from the pressing part 414 of the first operating member 410 and reset to the first position under the force of the second reset member 430, thereby interfering with the first operating member 410 and preventing the first operating member 410 from resetting to the locked position and the locking member 600 from resetting to the locked position.

[0044] Of course, in other embodiments, the sum of the dimensions of the second operating member 420 along the moving path of the first operating member 410 and the dimensions of the pressing part 414 along the moving path of the first operating member 410 may also be less than or equal to the distance the first operating member 410 moves from the locked position to the unlocked position, i.e., D+H≤L. In this way, when the first operating member 410 is in the unlocked position, the second operating member 420 will disengage from the pressing part 414 of the first operating member 410, and the second operating member 420 will automatically reset to the first position under the elastic restoring force of the second reset member 430 so as to be located on the moving path of the first operating member 410. In this way, the second operating member 420 can limit the first operating member 410 to the unlocked position, thereby keeping the locking member 600 in the unlocked position. When the user needs to reset the locking member 600 to the locked position, that is, when the first operating member 410 is reset to the locked position, the user must first operate (such as pressing) the second operating member 420 to move the second operating member 420 to the second position (that is, the second operating member 420 is moved out of the path of the first operating member 410). In this way, the first reset member 700 can drive the locking member 600 to automatically reset so as to drive the first operating member 410 to reset to the locked position.

[0045] The following diagrams briefly explain the process and principle of how the Sleeping Box 1000 flexibly changes between its extended and folded states.

[0046] Referring to Figures 1 to 3, when the sleeping box 1000 is in the extended state, the folding mechanism 300 is correspondingly in the unfolded state. At this time, the first support member 310 and the second support member 320 are approximately on the same straight line, and the first support member 310 and the second support member 320 are supported between the frame 100 and the base frame 200 to form a support space 101 for the infant to lie down. At this time, as shown in Figure 7, the first operating member 410 is in the locked position, and the second operating member 420 is in the first position. The second operating member 420 can abut against the pushing part 413 of the first operating member 410 to restrict the movement of the first operating member 410. At the same time, the locking protrusion 610 of the locking member 600 located in the inner cavity 313 of the first support member 310 passes through the through hole 314 and is inserted into the locking part 323 of the second support member 320 to restrict the first support member 310 from pivoting relative to the second support member 320. In this way, the folding mechanism 300 can be stably maintained in the unfolded state.

[0047] In one embodiment, the grip portion 411 includes an operating surface 4111 (refer to Figures 2 and 7), which is adapted to be operated by the user (e.g., pushed). Specifically, when the locking member 600 locks the folding mechanism 300 in the unfolded state, the first operating member 410 is in the locked position and the second operating member 420 is in the first position. The operating surface 4111 is located behind the second operating member 420 along the direction of movement of the first operating member 410 from the locked position to the unlocked position. Therefore, when the user needs to switch the sleeping box 1000 from the unfolded state to the folded state, as shown in Figure 2, the user first presses the second operating member 420 with their thumb or index finger to move the second operating member 420 to the second position. Subsequently, the user pushes the operating surface 4111 of the grip portion 411 upwards with their index or middle finger to move the first operating member 410 to the unlocked position (switching from Figure 2 to Figure 3). During the process of the first operating member 410 moving from the locked position to the unlocked position, the driving part 412 of the first operating member 410 drives the locking member 600 to move from the locked position to the unlocked position (switching from Figure 7 to Figure 8). After the locking protrusion 610 of the locking member 600 retracts from the locking part 323 of the second support member 320, the first support member 310 can pivot relative to the second support member 320 around the first pivot axis, so that the folding mechanism 300 switches to the folding state to fold the sleeping box 1000 (switching from Figure 3 to Figure 4).

[0048] It should be noted that when the sleeping box 1000 is in the extended state and the folding mechanism 300 is in the unfolded state, when the user releases the pushing or pulling force applied to the operating surface 4111 of the grip part 411 of the first operating member 410, the locking member 600 will automatically reset to the locked position with the elastic restoring force of the first reset member 700, the first operating member 410 will move and reset to the locked position with the locking member 600, and the second operating member 420 will automatically return to the first position with the elastic restoring force of the second reset member 430 and abut against the pushing part 413 of the first operating member 410 again.

[0049] Please refer to Figures 7 and 8. In the illustrated embodiment, the second pivot portion 322 of the second support member 320 has a guide surface 324. The guide surface 324 is arc-shaped and located on the outer periphery of the locking portion 323. After the locking protrusion 610 of the locking member 600 is disengaged from the locking portion 323, and the first support member 310 rotates relative to the second support member 320 about the first pivot axis to switch the folding mechanism 300 to the folded state, when the user releases the first operating member 410, the locking member 600 automatically abuts against the guide surface 324 under the elastic restoring force of the first reset member 700. At this time, the locking member 600 is in a position between the locked position and the unlocked position. At this time, the first operating member 410 can still press against the second operating member 420 to keep the second operating member 420 in the second position. When the folding mechanism 300 is in the folded state, the locking member 600 remains against the guide surface 324 under the elastic restoring force of the first reset member 700. The locking member 600 remains in a position between the locked and unlocked positions, and the first operating member 410 can still press against the second operating member 420. In this case, when the user needs to switch the sleeping box 1000 from the folded state to the unfolded state, the user can directly pull the frame 100 upward to drive the first support member 310 to rotate around the first pivot axis. The locking member 600 automatically moves to the unlocked position through the arc-shaped guide surface 324 and the first reset member 700. When the first support member 310 rotates to the point where the locking protrusion 610 is opposite to the locking part 323, the first reset member 700 drives the locking member 600 to reset so that the locking protrusion 610 is inserted into the locking part 323 to lock.

[0050] Optionally, in other embodiments, the guide surface 324 may be omitted. In this case, after the user releases the first operating member 410, the locking member 600 automatically resets to the locked position under the elastic reset force of the first reset member 700. Based on this, when the folding mechanism 300 is in the folded state, the locking member 600 resets to the locked position, and the second operating member 420 resets to the first position under the elastic reset force of the second reset member 430 to abut against the pushing part 413 of the first operating member 410. In this case, when the user needs to switch the sleeping box 1000 from the folded state to the unfolded state, the user needs to first press the second operating member 420 with their thumb or index finger to move the second operating member 420 to the second position. Then, the user pushes the gripping part 411 of the first operating member 410 upwards with their index or middle finger to move the first operating member 410 to the unlocked position. During the movement of the first operating member 410 from the locked position to the unlocked position, the driving part 412 of the first operating member 410 drives the locking member 600 to move, so that the locking protrusion 610 of the locking member 600 retracts into the inner cavity 313. This avoids interference between the locking protrusion 610 and the second support member 320, allowing the first support member 310 to fully unfold relative to the second support member 320. When the locking part 323 of the second support member 320 aligns with the locking protrusion 610, the user can directly release the first operating member 410. Under the force of the first reset member 700, the locking member 600 automatically moves from the unlocked position to the locked position, so that the locking protrusion 610 inserts into the locking part 323.
