Sleep basket and carrier

[0001] This application claims priority to Chinese patent application No. CN2024217787600 filed on July 25, 2024, international application No. PCT / CN2025 / 119510 filed on September 5, 2025, and German application No. DE102025 127 488.6 filed on July 14, 2025, the contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of infant products, in particular to a sleep basket and a carrier comprising the same. BACKGROUND

[0003] A sleep basket is usually provided on a carrier such as a trailer or a stroller for carrying and protecting an infant. When not in use, the sleep basket needs to be folded in half to save space.

[0004] Various foldable sleep baskets are disclosed in the prior art, for example, the sleep baskets disclosed in CN 208498578 U, CN 208909496 U, and CN 204838811 U. These sleep baskets can achieve a relatively compact storage state to facilitate storage or placement in the trunk of a car, but their overall structure is still considered to be less than ideal.

[0005] DISCLOSURE

[0006] A first aspect of the present disclosure provides a sleep basket, comprising:

[0007] a frame arrangement comprising two frames capable of relative rotation;

[0008] a carrier arrangement comprising two carriers capable of relative rotation;

[0009] a support arrangement comprising a first support and a second support capable of relative movement, the frame arrangement being connected to the first support, and the carrier arrangement being connected to the second support;

[0010] The sleep basket is capable of being converted between a use state and a storage state. During the conversion of the sleep basket from the use state to the storage state, the first support and the second support move relative to each other, causing the frame arrangement and the carrier arrangement to move closer to each other.

[0011] When the sleep basket of the present disclosure is converted from the use state to the storage state, the first support and the second support of the support arrangement move relative to each other, causing the frame arrangement and the carrier arrangement to move closer to each other, thereby achieving the folding of the sleep basket.

[0012] In some embodiments, the first support and the second support are arranged in a telescopic sliding manner, such that the two ends of the support device are close to each other in the storage state, so as to shorten the length of the support device itself, to compensate or offset the decreasing distance between the frame device and the bearing device, to avoid the support device from protruding outward during folding, so that the sleeping basket in the storage state is simple and compact in structure.

[0013] In some embodiments, the support device is provided with a first inclined support rod mechanism on each side, the first inclined support rod mechanism comprising a set of first inclined support rods, the two ends of each first inclined support rod being movably connected to the frame and the bearing on the same side of the support device, and the relative folding movement of a pair of frames and the relative folding movement of a pair of bearings being linked under the action of the two sets of first inclined support rod mechanisms.

[0014] In some embodiments, one side of the support device is provided with a first inclined support rod mechanism, and the other side is provided with a second inclined support rod mechanism, wherein the first inclined support rod mechanism comprises a set of first inclined support rods, the two ends of each first inclined support rod being movably connected to the frame and the bearing on the same side of the support device; the second inclined support rod mechanism comprises a second inclined support rod, the two ends of the second inclined support rod being movably connected to the frame and the bearing on the same side, so that the frame and the bearing connected by the first inclined support rod mechanism can be folded relative to the support device synchronously, while the frame and the bearing connected by the second inclined support rod mechanism can be folded relative to the support device asynchronously.

[0015] In some embodiments, the sleeping basket further has an intermediate state between the use state and the storage state, in which one of the bearings is opened relative to the support device, and the other bearing is folded relative to the support device. In this way, when a child is lying in the sleeping basket, the risk of the child being pinched after both bearings are folded relative to the support device can be avoided, effectively avoiding the safety risk caused by accidental touch or misoperation during actual use.

[0016] The second aspect of the present disclosure provides a sleeping basket, comprising a skeleton, the skeleton comprising:

[0017] a guide rail;

[0018] a sliding member moving along the guide rail;

[0019] a first surrounding rod assembly comprising a pair of first surrounding rods arranged in relative rotation, the pair of first surrounding rods being located on opposite sides of the guide rail and arranged in relative rotation to the guide rail;

[0020] a second pole assembly including a pair of second poles arranged in opposite rotation, the pair of second poles being arranged in opposite rotation relative to the slide and on opposite sides of the guide rail; the second poles on the same side of the guide rail being arranged in opposite vertical positions relative to the first poles; and

[0021] a pair of diagonal support pole mechanisms arranged on opposite sides of the guide rail, each diagonal support pole mechanism including a set of diagonal support poles, the two ends of the diagonal support poles being movably connected to the second poles and the first poles on the same side of the guide rail.

[0022] The sleeping basket of the present disclosure, the framework of which includes a pair of diagonal support pole mechanisms arranged on opposite sides of the guide rail, each diagonal support pole mechanism including a set of diagonal support poles, the two ends of the diagonal support poles being movably connected to the second poles and the first poles on the same side of the guide rail, and the sleeping basket can be folded by pressing the first pole assembly or the second pole assembly, which is more convenient to use.

[0023] A third aspect of the present disclosure provides a sleeping basket, comprising:

[0024] a fixed seat;

[0025] a first frame and a second frame capable of being relatively close and unfolded, one end of the first frame and the second frame close to each other being movably connected to the fixed seat;

[0026] a first locking structure arranged between the first frame and the fixed seat, capable of locking the first frame and the fixed seat, the second frame being capable of driving the first locking structure to be unlocked when being rotated relative to the fixed seat, so that the first frame can be rotated relative to the fixed seat and close to the second frame.

[0027] The sleeping basket provided by the present disclosure, when folding and storing the sleeping basket, the second frame is first rotated to be folded, the second frame being rotated relative to the fixed seat at the same time can trigger the first locking structure to be unlocked, and when the second frame is rotated to be folded in place, the first locking structure is unlocked, and then the limiting between the first frame and the fixed seat is released, so that the first frame can be rotated relative to the fixed seat. At this time, only the first frame needs to be rotated to be folded, and the first frame is close to the second frame, so that the folding of the sleeping basket is completed, and the unlocking operation of the first locking structure is not needed, thereby simplifying the folding operation steps of the sleeping basket, improving the convenience of the user folding and storing the sleeping basket, and improving the user experience.

[0028] A fourth aspect of the present disclosure provides a sleeping basket having a folded state and an unfolded state, the sleeping basket comprising:

[0029] a connecting seat;

[0030] The upright pole is slidably connected to the connecting seat and has a supporting position and a storage position. When the sleeping basket is in the unfolded state, the upright pole is in the supporting position.

[0031] The first frame assembly includes a first frame and a second frame that are rotatably connected to the upright;

[0032] The second frame assembly includes a third frame and a fourth frame that are rotatably connected to the connecting seat;

[0033] The support assembly includes a first support rod, the two ends of which are movably connected to the first frame and the third frame, respectively, and two of the first support rods are arranged on at least one side of the third frame in a first direction;

[0034] When the third frame rotates and unfolds relative to the connecting seat, the two first support rods can drive the first frame to unfold synchronously in the second direction, and cause the upright to slide synchronously relative to the connecting seat to the support position, with the first direction and the second direction forming an angle.

[0035] The bassinet provided in this disclosure features two first support rods arranged on at least one side of the third frame and the first frame in a first direction, forming a quadrilateral between the two support rods and the third and first frames. When the bassinet is switched from a folded state to an unfolded state, the third frame rotates and unfolds relative to the connecting seat, i.e., during the unfolding process of the third frame relative to the fourth frame, the quadrilateral structure allows the third frame to drive the first frame to unfold synchronously relative to the second frame via the two first support rods, achieving synchronous unfolding of the first and third frames. Simultaneously, since both the first and second frames are rotatably connected to the uprights, and the uprights are slidably connected to the connecting seat, the unfolding process of the first frame can drive the uprights to slide synchronously relative to the connecting seat. This ensures that when the first and third frames are fully unfolded, the uprights slide synchronously to the support position, thereby guaranteeing that the uprights, the first frame, and the third frame can lock synchronously, allowing the bassinet to accurately switch to and remain in the unfolded state. The design of this sleeping basket eliminates the need for users to operate the first and third frames separately when unfolding the basket, and also eliminates the need to extend the uprights to the support position separately. This simplifies the operation steps when unfolding the sleeping basket and improves the user experience.

[0036] The fifth aspect of this disclosure discloses a sleeping basket, including a frame, said frame comprising:

[0037] guide;

[0038] The slider moves along the guide rail;

[0039] a first pole assembly comprising a pair of first poles arranged in opposite rotation, the pair of first poles being located on opposite sides of the guide and arranged in opposite rotation relative to the guide;

[0040] a second pole assembly comprising a pair of second poles arranged in opposite rotation, the pair of second poles being located on opposite sides of the guide and arranged in opposite rotation relative to the sliding member, the second poles on the same side of the guide being opposite in vertical position to the first poles; and

[0041] a diagonal support rod mechanism comprising a set of diagonal support rods, two ends of the diagonal support rods being movably connected to the second poles and the first poles on the same side of the guide, respectively.

[0042] The sleeping basket provided by the present disclosure can form a quadrilateral structure with the two diagonal support rods of the diagonal support rod mechanism and the first poles and the second poles on the same side when folded, so that the first pole assembly and the second pole assembly can be folded synchronously, the folding operation steps are simplified, and the user experience is improved.

[0043] A sixth aspect of the present disclosure discloses a sleeping basket, comprising a framework, the framework comprising:

[0044] a first pole assembly comprising a pair of first poles arranged in opposite rotation;

[0045] a second pole assembly comprising a pair of second poles arranged in opposite rotation, the first pole assembly and the second pole assembly being arranged in opposite directions in the vertical direction, the first poles and the second poles on the same side being opposite in vertical position; and

[0046] a diagonal support rod mechanism connected between the first poles and the second poles on the same side, the diagonal support rod mechanism comprising a set of diagonal support rods, two ends of the diagonal support rods being movably connected to the second poles and the first poles on the same side, respectively.

[0047] The sleeping basket provided by the present disclosure can form a quadrilateral structure with the two diagonal support rods of the diagonal support rod mechanism and the first poles and the second poles on the same side when folded, so that the first pole assembly and the second pole assembly can be folded synchronously.

[0048] A seventh aspect of the present disclosure discloses a sleeping basket, in particular a portable sleeping basket with a structure as compact as possible and a construction and operation as simple as possible. In addition, a method for folding or unfolding the portable sleeping basket is also proposed.

[0049] In particular, the sleeping basket comprises:

[0050] - an upper frame;

[0051] - a bearing device;

[0052] - an adjustable support device connecting the upper frame and the carrier device to each other;

[0053] wherein the upper frame comprises a first frame section and a second frame section which are pivotable relative to each other, the carrier device comprises a first carrier section and a second carrier section which are pivotable relative to each other, and the portable sleeping basket is switchable from the use state to the storage state.

[0054] In some embodiments, the support device is arranged and configured such that, upon the transition from the use state to the storage state, the upper end and the lower end of the support device are brought closer to each other.

[0055] The core idea of this arrangement is that the support device is designed to be adjustable, in particular such that its two ends are brought closer to each other when the sleeping basket is switched to the storage state. Thereby, the shortening of the distance between the carrier device and the upper frame during the transition (i.e. folding) can be at least partially (or completely) compensated. In particular, the support device can be shortened (with "shortened" being understood as the two ends being brought closer to each other) in dependence of the distance. This measure can simply prevent (or at least reduce) the support device from protruding from the adjacent sections of the carrier device or the upper frame when folded, as it occurs in CN 208498578 U or CN 208909496 U.

[0056] In some embodiments (which can be realized alone or in combination with other embodiments), the use state and / or the storage state can be locked by the support device itself. Preferably, the locking is realized by the support device itself, i.e. by (directly) locking the two (movably and / or rotatably relative to each other) parts of the support device to each other. Thereby, the fixation of the use state and / or the storage state can be simply realized.

[0057] In a particularly preferred embodiment, the two sections of the support device are movably (e.g. telescopically) relative to each other, and the two sections are (directly) lockable to each other for locking the entire sleeping basket.

[0058] By "direct" locking as referred to herein, it is understood that no third component is involved between the elements or sections referred to. For example, if the above-mentioned preferred sections (support sections) are to be directly lockable to each other, this is not to be realized by indirectly locking the first and second carrier sections to each other. A particular advantage of the second aspect is that the support device itself can be used for locking the sleeping basket; it is not excluded that further locks are provided (e.g. for further security). Overall, this further simplifies the sleeping basket structure.

[0059] In some embodiments (which can be realized alone or in combination with other embodiments): the upper support section and the lower support section can be locked to each other in the use state and in at least one intermediate state between the use state and the storage state. Thereby, it can be prevented that the sleeping nest is accidentally refolded while not being fully unfolded, thereby improving safety and handling convenience. In the lockable intermediate state, the upper frame section and / or the lower support section is preferably pivoted at least 2% or at least 5% and / or at most 30% or at most 15% of the maximum pivoting angle (between the (maximum) use state and the (maximum) storage state).

[0060] Herein, "upper" and "lower" shall in particular refer to the position of the respective structure when the sleeping nest is in the use state and is placed horizontally.

[0061] According to a seventh aspect of the present disclosure, in some embodiments, the sleeping nest has one or more of the following structures or configurations:

[0062] a) The upper frame is divided into a first frame section and a second frame section by the upper hinge means, which hinge the two sections; and / or, the carrier means is divided into a first carrier section and a second carrier section by the lower hinge means, which hinge the two sections.

[0063] b) The upper end of the support means is connected to the first and / or second frame section of the upper frame by the upper hinge means; and / or, the lower end of the support means is connected to the first and / or second frame section of the lower frame by the lower hinge means. (It is also possible to provide separate hinge means at the upper and lower end of the support means for connecting to the respective frame sections.)

[0064] c) The hinge means can be formed by a continuous structure or by separate structures (e.g. by separate hinges on the left and right side).

[0065] d) The sleeping nest has a head end and a foot end, which can be defined by the upper frame and / or the carrier means.

[0066] e) Use state: the first distance between the upper hinge means and the lower hinge means, and the head end and the foot end are apart from each other;

[0067] Storage state: the second distance between the upper hinge means and the lower hinge means (which is smaller than the first distance), and the head end and the foot end are close to each other.

[0068] - First distance: > 8 cm, preferably > 11 cm, more preferably > 14 cm and / or < 28 cm, preferably < 25 cm, more preferably < 22 cm.

[0069] - Second distance: > 2 cm, preferably > 3 cm, more preferably > 5 cm and / or < 15 cm, preferably < 12 cm, more preferably < 10 cm.

[0070] (The above distances are measured relative to the respective pivoting axis.)

[0071] f) The "proximity" of the head end and the foot end means that, in the stowed state, the distance between them is ≤ 40% of the length of the sleeping basket in the use state, preferably ≤ 20%, or ≤ 15 cm, preferably ≤ 10 cm.

[0072] g) The distance between the two ends of the support device and / or the distance between the rotation axes of the upper and lower hinge devices should be reduced by at least 10%, preferably at least 20%, if necessary at least 50% or up to 80% (relative to the initial distance in the use state).

[0073] h) The support device preferably comprises at least (or exactly) two support sections that are rigid in themselves and movable relative to each other, in particular at least one upper support section and at least one lower support section; it can also be at least partially flexible / bendable (e.g. provided with film hinges).

[0074] i) When transitioning from the use state to the stowed state, the two support sections can: slide relative to each other via a telescoping mechanism and / or guide rails; or pivot relative to each other via adjustment hinges (the adjustment hinges can be located in the central third of the support device, rotating about a horizontal longitudinal or transverse axis).

[0075] j) In the stowed state, the upper support section and the lower support section can be nested into each other or placed side by side, with a nesting height of at least 70% or completely, and / or at least 8 cm or 10 cm.

[0076] k) At least one linkage is provided for coupling the movement of the first frame section to the first bearing section and / or the second frame section to the second bearing section, enabling simultaneous folding. The linkage can be U-shaped, with at least 50% of its weight being metal; its free end is rotationally connected to the upper frame, the cross section is rotationally connected to the bearing device, and the cross section is closer to the lower hinge device.

[0077] l) The lower hinge device can be a single hinge (extending transversely) or a left-right split hinge; the upper hinge device is preferably left-right split, and can also be a single hinge.

[0078] m) The sleeping basket is provided with an adapter for detachable connection to a base (e.g. a stroller frame); the adapter is integrated with the lower and / or upper hinge device. Tool-free locking is achieved between the adapter and the base by means of a buckle / quick release.

[0079] n) The upper support section can be provided with a support rod; the lower support section can be provided with a support rod or a disc (the disc profile can be circular or polygonal), and is integrated with the lower hinge device and / or the adapter.

[0080] o) The upper support section and the lower support section can be directly locked to each other, and the locking positions include the use state, the stowed state, and / or an intermediate state.

[0081] p) a locking mechanism for locking the sleeping basket in the use state; the locking mechanism can lock between the frame segments, between the carrier segments and / or between the support segments, or the carrier segments can be locked directly with the upper support segments or the frame segments with the lower support segments. The locking mechanism comprises spring-biased pins, which can be moved between the locked and unlocked position.

[0082] The present disclosure also relates to a method for stowing or unfolding the above-mentioned portable sleeping basket: by pivoting the first carrier segment relative to the second carrier segment, the upper frame segments can be folded or unfolded simultaneously under the action of the linkage; the support device is shortened or lengthened accordingly and is locked directly in the desired position, completing the state transition.

[0083] According to the present disclosure, in an embodiment, two bolt receiving portions can be provided, one of which corresponds to the (fully unfolded) use state and the other of which corresponds to the (almost) fully unfolded state ("emergency position"). Alternatively or additionally, two bolts can also be provided, one of which (in the corresponding bolt receiving portion) corresponds to the (fully unfolded) use state and the other of which corresponds to the (almost) fully unfolded state ("emergency position"). In this way, it can be prevented that the sleeping basket is accidentally folded again when it is not fully unfolded.

[0084] The (respective) bolt can be moved in rotation and / or translation relative to the element in which or on which it is accommodated or supported. The bolt can be equipped with a (manual) operating device, which is formed, for example, by a lever, a slider and / or a button or which comprises the aforementioned elements and can be switched between an actuated state and a non-actuated state. An active connection (transmission element), for example a rod and / or a cable, such as a steel cable, can be arranged between the operating device and the bolt, so that when the operating device is actuated, the bolt is moved from the locked position to the unlocked position. Alternatively or additionally to the bolt, the transmission element itself can also be spring-loaded (or the active connection comprises a spring).

[0085] The operating device can be arranged at one of the head end or the foot end, preferably at the foot end.

[0086] If the bolt is arranged at one of the first carrier segment, the second carrier segment or the lower support segment, the operating device is preferably arranged on the support device (lower frame or bottom plate).

[0087] If the bolt is arranged at one of the first frame segment, the second frame segment or the upper support segment, the operating device is preferably arranged on the upper frame.

[0088] Preferably, a carrying handle, in particular a hinged carrying handle, is provided on the upper frame, in particular on the first frame segment.

[0089] According to an embodiment, the carrier device comprises a bottom plate, which has a turned-up edge (raised edge), in particular.

[0090] The above task is also solved by a method for folding up or folding down (or folding up and folding down method) a sleeping basket of the above type, wherein the first carrier section and the second carrier section are pivoted towards or away from each other.

[0091] The upper frame can be designed as a tube or as a profile, for example as a U-profile (or partly as a tube and partly as a profile). The upper frame is preferably one piece and continuous (not excluding that parts thereof are formed by hinge means).

[0092] The upper frame can be made of metal (in particular aluminium or an aluminium alloy) and / or plastic (preferably at least 40% by weight metal and / or at least 40% by weight plastic).

[0093] The head end of the upper frame can be wider than the foot end.

[0094] The first frame section and the second frame section can each be U-shaped.

[0095] The carrier means can comprise a lower frame (preferably metal, in particular aluminium alloy, at least 40% by weight, and / or plastic, at least 40% by weight) and / or a bottom plate (preferably at least 40% by weight, more preferably at least 80% by weight plastic). The same applies to the first and second carrier sections.

[0096] If a bottom plate is provided, (at least) one corresponding plate section can be recessed in the centre (in the transverse direction) and in the region of the lower hinge means, so that the sleeping basket can be supported in the folded-up state in the recess. The optional bottom plate can be trough-shaped or have a flange.

[0097] The folding movement between the use state and the folded-up state can be limited by at least one corresponding stop (for example in one of the upper and lower hinges and / or in two elements connected to each other in the upper hinge means or in the lower hinge means).

[0098] The bottom plate can be provided with a transverse groove for (rotatably) accommodating a transverse section of one or more (corresponding) link elements. The bottom plate can be provided with one or more channels for accommodating the respective (Bowden) wire. Retaining elements (screwed and / or partly covering the corresponding channels, if necessary) can be provided for retaining the link elements on the bottom plate.

[0099] The lower hinge means (in particular the left and right lower hinges) can be arranged above (slightly above, for example at least 2 cm or at least 4 cm and / or at most 10 cm relative to the corresponding hinge axis of rotation) the (upper) plate surface of the bottom plate. In this way, the cavity between the plate sections in the folded-up state can be kept small, which cavity in the folded-up state can be used to accommodate frame sections, link elements, soft goods and / or sleeping bags, etc.

[0100] If the upper and lower support sections are telescopic, the lower support section (in particular the disc-shaped one) can accommodate the upper support section completely (in the height direction) in the folded-up state; the inward section belonging to the upper hinge can remain unaccommodated.

[0101] Alternatively or additionally, in use, at least 25%, preferably at least 40%, if necessary at least 50% and / or at most 70% or at most 60% of the length of the upper support section can be accommodated in the lower support section (improving stability).

[0102] The upper support section can comprise or be formed by a metal strut.

[0103] The upper support section can be provided with two (especially stacked on top of each other) bolt receiving portions.

[0104] The lower hinge arrangement (or corresponding left / right lower joint) can (per side) comprise:

[0105] - a first disc for the first carrier section,

[0106] - a second disc for the second carrier section (with recess and screw- fixable cover plate),

[0107] - a third disc for the lower support section (or formed by it),

[0108] - a fourth disc for the adapter.

[0109] The (corresponding) discs can be integrally formed with at least part of the corresponding element.

[0110] The third disc (lower support section) can be provided with a cavity with an opening (especially lateral).

[0111] The upper hinge arrangement (or corresponding left / right upper joint) can be provided with:

[0112] - a first disc for the first frame section,

[0113] - a second disc for the second frame section,

[0114] - a third disc for the upper support section.

[0115] The bolt can be rotatably mounted in the lower support section (especially in the cavity). The bolt can have a fixation section, an engagement section and a drive section.

[0116] The manipulation arrangement can be moved in longitudinal backward translation at the foot end of the base plate to transfer the bolt to the unlocked position. The manipulation arrangement can be (directly) connected to a first end of a corresponding wire rope, which is guided through a corresponding channel / groove of the base plate to each lower joint. A second end of the wire rope can be connected to a slider. The slider can be slidingly coupled with the disc corresponding to the second plate section through a long hole (especially in a recess below the cover plate); the slider can be spring biased (towards the unmanipulated position) and can be provided with a protrusion.

[0117] Upon actuation of the manipulation arrangement or pulling of the wire rope, the slider is moved along the long hole, the protrusion extends into the cavity through the lateral opening and presses against the drive section of the bolt, causing the bolt to rotate, the engagement section to disengage the corresponding bolt receiving portion and the upper and lower sections to be freely slidable relative to each other, the sleeping basket can be transferred into the stowed state.

[0118] According to the sleeping basket provided by the present disclosure, when the sleeping basket is transferred from the storage state to the use state (i.e. unfolded), the upper support section support rod slides along the lock bolt engaging section (the spring presses the lock bolt towards the support rod), until the engaging section is first clamped into the upper one of the two lock bolt receiving portions (the "emergency position") and finally clamped into the lower one (fully unfolded). The engaging section preferably slides into the lower receiving portion from the upper receiving portion in a ratchet manner (through a slope); when the engaging section is located in any receiving portion, the downward movement of the upper support section is prevented (preferably by a lock, which can only be unlocked by operating the device).

[0119] In the initial stage of the storage process, at least or exactly one of the first carrying section, the second carrying section, the first frame section and the second frame section (especially the second carrying section facing the head end) does not pivot relative to the support device.

[0120] It can be provided that a corresponding pair of the first carrying section and the first frame section or the second carrying section and the second frame section can pivot synchronously, especially in parallel (during the storage process). It can also be provided that the corresponding pair cannot pivot in parallel (or synchronously). In a specific embodiment, the first carrying section and the first frame section can pivot in parallel (and preferably also remain parallel subsequently) from the initial stage of the pivoting starting from the use state, while the second carrying section and the second frame section cannot pivot in parallel in this initial stage (and subsequently at least not in parallel, even if the movements are synchronous).

[0121] The eighth aspect of the present disclosure also discloses a carrier comprising a support frame and a sleeping basket as described above, wherein the sleeping basket is mounted on the support frame. The support frame is preferably a stroller frame. The carrier comprising the sleeping basket as described above must have the advantages possessed by the sleeping basket, so that the overall use experience of the user when using the carrier is greatly improved.

[0194] In FIGS. 1-6, the following are marked:

[0195] 11, first frame; 12, second frame; 21, first carrier; 22, second carrier; 31, first support; 2, second support; 41, first diagonal strut; 51, second diagonal strut; 6, handle.

[0196] Referring to Figs. 1-6, one embodiment of the present disclosure provides a sleeping basket, which comprises:

[0197] a frame device comprising two frames capable of relative rotation, specifically, first frame 11 and second frame 12;

[0198] a carrier device comprising two carriers capable of relative rotation, specifically, first carrier 21 and second carrier 22;

[0199] a support device comprising first support 31 and second support 32 capable of relative movement, the frame device is connected to first support 31, and the carrier device is connected to second support 32;

[0200] wherein the sleeping basket can be converted between a use state and a storage state, and during the conversion, first support 31 and second support 32 can move relative to each other, so that the frame device and the carrier device move closer to each other.

[0201] Specifically, first support 31 and second support 32 are arranged in relative sliding manner, specifically, one of first support 31 and second support 32 is a guide rail, and the other is a sliding member, and the sliding member is slidingly arranged on the guide rail, and the relative approach or separation between the frame device and the carrier device is realized by the sliding movement of the sliding member relative to the guide rail. In this embodiment, first support 31 and second support 32 are connected in sliding and telescopic manner, and during the conversion from the use state to the storage state, the two ends of the support device move closer to each other, so that the overall length of the support device is shortened, thus avoiding the outward protrusion of the support device during folding, and making the sleeping basket in the storage state simple and compact in structure.

[0202] In this embodiment, first frame 11 and second frame 12 are connected to first support 31 respectively, and first carrier 21 and second carrier 22 are connected to second support 32 respectively, wherein first frame 11 and first carrier 21 are located on the same side of the support device, and second frame 12 and second carrier 22 are located on the other side of the support device. In the use state, first frame 11 and second frame 12 form a closed frame structure on both sides of the support device, and handle 6 can be connected to first frame 11 for lifting the sleeping basket or used as a tent pole of the sleeping basket; first carrier 21 and second carrier 22 are relatively unfolded to provide lying support, and in some embodiments, a bottom plate can be arranged on first carrier 21 and second carrier 22, which can be in the form of a shallow basin.

[0203] The two carriers can be folded by being turned towards each other so that the two frames are folded in the two carriers, and in this folding mode, the two carriers are both turned upwards so that the carrying surfaces of the two carriers face each other in the folded state of the sleeping basket. Alternatively, the two carriers can be folded by being turned away from each other so that the two frames are folded between the two carriers, and in this folding mode, the two carriers are both turned downwards so that the carrying surfaces of the two carriers face outwards in the folded state of the sleeping basket.

[0204] The sleeping basket provided in the embodiment further has an intermediate state between the use state and the folded state, in which the first carrier 21 is unfolded relative to the support device, and the second carrier 22 is folded relative to the support device. When the sleeping basket is folded, the second carrier 22 is first folded relative to the support device, and then the first carrier 21 is folded relative to the support device. In this way, when a child is lying in the sleeping basket, the risk that the child is pinched after the first carrier 21 and the second carrier 22 are both folded relative to the support device can be avoided, and the safety risk caused by accidental touching or misoperation in actual use can be effectively avoided. As a preferred arrangement, the head of the child is supported on the first carrier 21, and the feet of the child are supported on the second carrier 22.

[0205] The sleeping basket provided in the embodiment further comprises a first inclined support rod mechanism arranged between the second carrier 22 and the second frame 12 to link the folding of the second carrier 22 and the second frame 12 relative to the support device. The first inclined support rod mechanism comprises two first inclined support rods 41, the two ends of the two first inclined support rods 41 are respectively movably connected, specifically rotatably connected, to the second carrier 22 and the second frame 12, and the two first inclined support rods 41 are arranged in parallel or approximately parallel to each other. In this way, when the second frame 12 is folded relative to the support device, the second carrier 22 is synchronously folded relative to the support device under the action of the two first inclined support rods 41.

[0206] The sleeping basket of the embodiment further comprises a second inclined support rod mechanism, and the second inclined support rod mechanism comprises a second inclined support rod 51. When the first frame 11 is turned relative to the support device, the second inclined support rod 51 cannot drive the first carrier 21 to synchronously turn relative to the support device, so that the first carrier 21 and the second carrier 22 are folded relative to the support device out of synchronization, thereby avoiding the safety risk caused by misoperation.

[0207] The sleeping basket further comprises a first locking structure arranged between the first bearing member 21 and the second support member 32 for locking the first bearing member 21 and the second support member 32, wherein the first locking structure is unlocked when the second bearing member 22 rotates relative to the second support member 32, so that the first bearing member 21 rotates relative to the second support member 32 to fold in, that is, the first bearing member 21 and the second bearing member 22 can rotate relative to the support device to fold in with a certain time difference, so as to timely correct the misoperation during this period.

[0208] The second bearing member 22 and the second support member 32 are provided with a second locking structure, which can limit the first locking structure in the locked position to avoid the first locking structure being unlocked; the first support member 31 and the second support member 32 are further provided with a third locking structure, which can be unlocked at the same time when the second locking structure is unlocked, so as to simplify the folding operation of the sleeping basket.

[0209] The specific structure of the first locking structure, the second locking structure and the third locking structure is not described in detail in this embodiment, and will be described in detail in the following text combined with the embodiments of B1-B14.

[0210] When the sleeping basket provided in this embodiment is converted from the use state to the storage state, referring to FIGS. 1-2, the second bearing member 22 rotates relative to the second support member 32 and the first bearing member 21, and the first bearing member 21 has not yet rotated, and the first frame 11 and the second frame 12 also rotate relative to the support device; continuing to refer to FIGS. 3-4, the second bearing member 22, the second frame 12 and the first frame 11 continue to fold in, and the first bearing member 21 still remains not rotating.

[0211] Next, referring to FIG. 5, at this time, the second bearing member 22 has been substantially parallel to the support device with the second frame 12, and the first frame 11 continues to fold inward, and the first bearing member 21 begins to rotate. Referring to FIGS. 6-7, the storage is completed, and the first frame 11, the second frame 12, the first bearing member 21 and the second bearing member 22 are substantially parallel to the support device. The distance between the rotation axis of the surrounding frame device and the rotation axis of the support device is converted from L1 to L2, which is significantly reduced.

[0212] Now further detailed description of the sleeping basket according to another embodiment of the present disclosure will be made in combination with FIGS. A1-A14. Unless otherwise specified, the figures in this section are described in combination with one or more of FIGS. A1-A14. Among them, the reference signs of FIGS. A1-A14 are explained as follows:

[0213] The reference signs in Figs. A1-A14 are:

[0214] 1, guide rail; 4, sliding member; 7, unlocking member; 21, first orientation first surrounding rod; 22, first orientation second surrounding rod; 31, first pivot connecting member; 32, second pivot connecting member; 33, third pivot connecting member; 34, pivot shaft; 51, second orientation first surrounding rod; 52, second orientation second surrounding rod; 61, first inclined support rod; 62, second inclined support rod.

[0215] It should be understood that in the sleeping basket shown in Figs. A1-A14, the guide rail 1 and the sliding member 4 correspond to the first support member and the second support member in the support device; the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 correspond to the two frames in the surrounding frame device; the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 correspond to the two load bearing members in the load bearing device; the first inclined support rod mechanism is arranged on both sides of the support device in the sleeping basket, and the first inclined support rod 61 and the second inclined support rod 62 correspond to the two first inclined support rods of the first inclined support rod mechanism. The present embodiment will be described in detail below in conjunction with the relevant drawings.

[0216] Referring to Figs. A1-A14, the present embodiment provides a sleeping basket and a carrier including the sleeping basket, which can be but is not limited to a stroller, a trailer, a cradle or a safety seat. Specifically, the carrier further includes a base, and the sleeping basket is detachably or non-detachably mounted to the base. The specific connection manner between the sleeping basket and the base is not limited, and the connection structure in the prior art can be used. The sleeping basket includes a framework and an outer covering made of a flexible material (for example, cloth or plastic), and the outer covering can be sleeved on the framework to form a basket-shaped structure for protecting an infant.

[0217] As shown in Figs. A1-A14, the framework of the sleeping basket includes a guide rail 1, a sliding member 4, a first surrounding rod assembly, a second surrounding rod assembly and a pair of inclined support rod mechanisms, wherein the sliding member 4 is sleeved on the guide rail 1 and can move along the guide rail 1, and the inclined support rod mechanisms are arranged on both sides of the guide rail 1, each of the inclined support rod mechanisms includes a group of inclined support rods, and the two ends of the inclined support rods are respectively movably connected with the second surrounding rod and the first surrounding rod on the same side of the guide rail 1. In the present embodiment, the pair of inclined support rod mechanisms are arranged in axial symmetry relative to the guide rail 1, and the stress is more balanced; the two ends of the inclined support rods are respectively rotatably connected with the first surrounding rod and the second surrounding rod, the sleeping basket can be smoothly folded, and the connection structure between the inclined support rods and the first surrounding rod and between the inclined support rods and the second surrounding rod is more stable.

[0218] The first rail assembly comprises a pair of first rails arranged in opposite rotation, and the pair of first rails are located on opposite sides of the guide rail 1 and arranged in opposite rotation with the guide rail 1. The second rail assembly comprises a pair of second rails arranged in opposite rotation, and the pair of second rails are located on opposite sides of the guide rail 1 and arranged in opposite rotation with the sliding member 4; the second rails located on the same side of the guide rail 1 are opposite to the first rails in the vertical direction.

[0219] Specifically, the first rail assembly comprises a first-position first rail 21 and a first-position second rail 22, and in the first position, the first-position first rail 21 and the first-position second rail 22 are located on opposite sides of the guide rail 1; the second rail assembly comprises a second-position first rail 51 and a second-position second rail 52, and the end of the second-position first rail 51 and the second-position second rail 52 is respectively pivoted to the sliding member 4.

[0220] When the pair of first rails are folded together, the pair of second rails are synchronously folded together under the action of the inclined support rod mechanism, and at this time, the sliding member 4 slides towards the direction close to the first rail assembly. In the embodiment, the first-position first rail 21 and the first-position second rail 22 can be pivoted towards the guide rail 1 until the sleeping basket is folded in half, which is convenient for storage and carrying. After the sleeping basket is folded in half, the pivoting ends of the guide rail 1, the first-position first rail 21 and the first-position second rail 22 are all located within the range of the pivoting assembly, that is, the width of the folded sleeping basket is equal to the maximum width L of the pivoting assembly, the whole sleeping basket is more flat, occupies less space, and is convenient for carrying out. The position where the guide rail 1, the first-position first rail 21 and the first-position second rail 22 are connected is the folding position of the sleeping basket.

[0221] The "first position" of the first-position first rail 21 and the first-position second rail 22 can be, but is not limited to, up and down. Specifically, as shown in FIG. A1, the first position is "up", and the first-position first rail 21 and the first-position second rail 22 are both located above the overall structure of the sleeping basket; as shown in FIG. A9, the first position is "down", and the first-position first rail 21 and the first-position second rail 22 are both located below the overall structure of the sleeping basket. Whether the first-position first rail 21 and the first-position second rail 22 are located above or below the overall structure of the sleeping basket, the use method is the same, and the difference is only that the sleeping basket is folded downward (as shown in FIG. A5 and FIG. A8) or upward (as shown in FIG. A11 and FIG. A14), which can be selected according to the needs of the user.

[0222] The "second orientation" of the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 is arranged opposite to the "first orientation". As shown in FIG. A1, when the first orientation is "up", the second orientation is "down", the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 are located above the overall structure of the sleeping basket, and the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 are located below the overall structure of the sleeping basket; as shown in FIG. A9, when the first orientation is "down", the second orientation is "up", the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 are located below the overall structure of the sleeping basket, and the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 are located above the overall structure of the sleeping basket. Whether the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 are located above or below the overall structure of the sleeping basket, the use method is the same, and the difference is only that the sleeping basket is folded downward (as shown in FIG. A5 and FIG. A8) or upward (as shown in FIG. A11 and FIG. A14), which can be selected according to the needs of the user.

[0223] Specifically, in the vertical direction, the first surrounding rod assembly is arranged on the upper side of the second surrounding rod assembly, the position where the diagonal support rod is connected with the first surrounding rod is arranged on one end of the first surrounding rod close to the guide rail 1, and the position where the diagonal support rod is connected with the second surrounding rod is arranged on one end of the second surrounding rod away from the sliding member 4; when the second surrounding rod assembly is closed, the second surrounding rod is flipped downward and drives the sliding member 4 to slide upward.

[0224] Another structure, in the vertical direction, the second surrounding rod assembly is arranged on the upper side of the first surrounding rod assembly, the position where the diagonal support rod is connected with the first surrounding rod is arranged on one end of the first surrounding rod close to the guide rail 1, and the position where the diagonal support rod is connected with the second surrounding rod is arranged on one end of the second surrounding rod away from the sliding member 4; when the second surrounding rod assembly is closed, the second surrounding rod is flipped upward and drives the sliding member 4 to slide downward.

[0225] On the basis of the above structure, each pair of diagonal support rod mechanisms includes two parallel first diagonal support rods 61 and second diagonal support rods 62, the first diagonal support rods 61 and the second diagonal support rods 62 can form a parallelogram structure with the first orientation first surrounding rod 21 and the second orientation first surrounding rod 51 (or the first orientation second surrounding rod 22 and the second orientation second surrounding rod 52), and the first surrounding rod assembly can drive the sliding member 4 to move along the guide rail 1 through the diagonal support rod mechanism and the second surrounding rod assembly. The first diagonal support rods 61 and the second diagonal support rods 62 can be connected with the first orientation first surrounding rod 21 and the second orientation first surrounding rod 51 (or the first orientation second surrounding rod 22 and the second orientation second surrounding rod 52) in a sliding connection or a rotating connection, which does not affect the normal use of the sleeping basket.

[0226] It should be noted that the first inclined support rod 61 and the second inclined support rod 62 are substantially parallel, so that the overall structure of the sleeping basket is more compact when folded. If there is a certain angle between the first inclined support rod 61 and the second inclined support rod 62, it does not affect the folding and normal use of the sleeping basket, but there is a larger opening after folding.

[0227] Specifically, as shown in FIGS. A4, A7, A10 and A13, the user holds the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 and presses them towards the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52, so that the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 are respectively pivoted about the guide rail 1. The inclination angle of the first inclined support rod 61 and the second inclined support rod 62 relative to the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22 changes, and in the vertical direction, the end of the first inclined support rod 61 connected to the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22) is farther away from the second orientation first surrounding rod 51 (or the second orientation second surrounding rod 52) than the end of the second inclined support rod 62 connected to the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22). The total length of the first inclined support rod 61 does not change, so the first inclined support rod 61 will pull the second orientation first surrounding rod 51 (or the second orientation second surrounding rod 52) through the connection point of the first inclined support rod 61 and the second orientation first surrounding rod 51 (or the second orientation second surrounding rod 52), so that the second orientation first surrounding rod 51 always maintains parallelism with the first orientation first surrounding rod 21, and the second orientation second surrounding rod 52 always maintains parallelism with the first orientation second surrounding rod 22. When the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 are inclined, they can push the sliding member 4 to move along the guide rail 1, thereby achieving folding of the sleeping basket, and the use is more convenient. The folding mode can be selected according to the actual situation, and the use experience is good.

[0228] Moreover, compared with the structure of using one inclined support rod on one side in the prior art, the present embodiment uses two inclined support rods to constrain the folding mode of the rotation of one inclined support rod relative to the other inclined support rod, thereby realizing synchronous folding of the two sides of the sleeping basket.

[0229] Of course, the sleeping basket can also have the same folding mode as the existing sleeping basket, that is, the sliding member 4 is pushed to move along the guide rail 1 towards the pivot assembly, thereby driving the first orientation first surrounding rod 21, the first orientation second surrounding rod 22, the second orientation first surrounding rod 51 and the second orientation second surrounding rod 52 to respectively pivot towards the guide rail 1, until the sleeping basket is folded.

[0230] On the basis of the above structure, in order to enable the first-orientation first surrounding rod 21, the first-orientation second surrounding rod 22, the second-orientation first surrounding rod 51 and the second-orientation second surrounding rod 52 to synchronously swing, the sleeping basket comprises at least two groups of inclined supporting rod mechanisms, at least one group of the inclined supporting rod mechanisms being pivotally connected between the first-orientation first surrounding rod 21 and the second-orientation first surrounding rod 51, and at least one group of the inclined supporting rod mechanisms being pivotally connected between the first-orientation second surrounding rod 22 and the second-orientation second surrounding rod 52.

[0231] In the embodiment, the first-orientation first surrounding rod 21, the second-orientation first surrounding rod 51, the first inclined supporting rod 61 and the second inclined supporting rod 62 form a four-bar linkage structure, when the sleeping basket is folded, the first inclined supporting rod 61 and the second inclined supporting rod 62 do not affect the swinging of the first-orientation first surrounding rod 21 and the second-orientation first surrounding rod 51 towards the guide rail 1; when the sleeping basket is in an unfolded state, the first inclined supporting rod 61 and the second inclined supporting rod 62 can play a supporting role between the first-orientation first surrounding rod 21 and the second-orientation first surrounding rod 51, so that the unfolded state of the sleeping basket is more stable, and can play a supporting role on the outer covering surface.

[0232] Similarly, the first-orientation second surrounding rod 22, the second-orientation second surrounding rod 52, the first inclined supporting rod 61 and the second inclined supporting rod 62 form a four-bar linkage structure, when the sleeping basket is folded, the first inclined supporting rod 61 and the second inclined supporting rod 62 do not affect the swinging of the first-orientation second surrounding rod 22 and the second-orientation second surrounding rod 52 towards the guide rail 1; when the sleeping basket is in an unfolded state, the first inclined supporting rod 61 and the second inclined supporting rod 62 can play a supporting role between the first-orientation second surrounding rod 22 and the second-orientation second surrounding rod 52, so that the unfolded state of the sleeping basket is more stable, and can play a supporting role on the outer covering surface.

[0233] In order to avoid interference of the first inclined supporting rod 61 and the second inclined supporting rod 62 after the sleeping basket is folded, one of the first inclined supporting rod 61 and the second inclined supporting rod 62 is connected to one side of the first-orientation first surrounding rod 21 or the first-orientation second surrounding rod 22, and the other of the first inclined supporting rod 61 and the second inclined supporting rod 62 is connected to the other side of the first-orientation first surrounding rod 21 or the first-orientation second surrounding rod 22.

[0234] As shown in FIG. A1, the top end of the first inclined support rod 61 is connected to the outer side of the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22), and the top end of the second inclined support rod 62 is connected to the inner side of the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22). Among them, the "outer side" and the "inner side" are based on the center of the sleeping basket. The side of the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22) facing the center of the sleeping basket is the inner side, and the side away from the center of the sleeping basket is the outer side. After the sleeping basket is folded, the top end of the first inclined support rod 61 is located on the outer side of the sleeping basket, and the top end of the second inclined support rod 62 is located on the inner side of the sleeping basket, that is, the top end of the first inclined support rod 61 and the top end of the second inclined support rod 62 are separated by the first orientation first surrounding rod 21 (or the first orientation second surrounding rod 22), so that the first inclined support rod 61 and the second inclined support rod 62 do not extrude and collide with each other, the sleeping basket is folded more smoothly, the folding efficiency is high, and the use experience is good.

[0235] The specific inclination direction of the inclined support rod mechanism is not limited. In the present embodiment, the other end of the inclined support rod mechanism connected to the second orientation first surrounding rod 51 or the second orientation second surrounding rod 52 is away from the guide rail 1 relative to the one end connected to the first orientation first surrounding rod 21 or the first orientation second surrounding rod 22. The overall strength of the sleeping basket is higher, and the folding is more convenient.

[0236] On the basis of the above structure, the pivot assembly includes a first pivot piece 31, a second pivot piece 32 and a third pivot piece 33 connected to the same pivot shaft 34. The first pivot piece 31 is connected to the pivot end of the first orientation first surrounding rod 21, the second pivot piece 32 is connected to the pivot end of the first orientation second surrounding rod 22, and the third pivot piece 33 is connected to the pivot end of the guide rail 1.

[0237] In order to realize that the width of the folding part of the sleeping basket after folding is equal to the maximum width L of the pivot assembly, in the present embodiment, the first pivot piece 31 is disc-shaped, and the first orientation first surrounding rod 21 is tangent to the first pivot piece 31; and / or, the second pivot piece 32 is disc-shaped, and the first orientation second surrounding rod 22 is tangent to the second pivot piece 32. This structure does not affect the strength of the first orientation first surrounding rod 21 and the first orientation second surrounding rod 22, and prolongs the service life of the sleeping basket. The first orientation first surrounding rod 21 is tangent to the first pivot piece 31, and after the sleeping basket is folded, the pivot end connected by the first orientation first surrounding rod 21 and the first pivot piece 31 will not exceed the outer circumference of the first pivot piece 31, thereby ensuring that the width of the folding part is equal to the maximum width L of the pivot assembly, and the occupied space is small. Similarly, the pivot end connected by the first orientation second surrounding rod 22 and the second pivot piece 32 will not exceed the outer circumference of the second pivot piece 32, thereby ensuring that the width of the folding part is equal to the maximum width L of the pivot assembly.

[0238] The specific structure of the hinge assembly is not limited, and in the embodiment, the outer peripheral shapes and areas of the first hinge member 31, the second hinge member 32, and the third hinge member 33 are all the same. The width (diameter) of any one of the first hinge member 31, the second hinge member 32, and the third hinge member 33 is the maximum width L of the hinge assembly, which reduces the width of the folding part and reduces the occupied space while ensuring that the hinge assembly has sufficient strength.

[0239] On the basis of the above structure, the sleeping basket further comprises a locking member and an unlocking member 7, the locking member is detachably connected to the guide rail 1, and the unlocking member 7 is connected to the locking member. The locking member is used to fix the sliding member 4 on the guide rail 1, and pulling the unlocking member 7 can separate the locking member and the guide rail 1. The unlocking member 7 can be, but is not limited to, a pull rope and a carrying strap, the locking member is a latch, the sliding member 4 is provided with a through hole (not shown), and the guide rail 1 is provided with a plug hole (not shown) opposite to the through hole. In the embodiment, two guide rails 1 are provided with sliding members 4, the two sliding members 4 are provided with locking members, and the unlocking member 7 is connected between the two locking members.

[0240] When the sleeping basket is in the unfolded state, the latch is inserted into the plug hole on the guide rail 1 after passing through the through hole on the sliding member 4, so that the sliding member 4 is fixed relative to the guide rail 1, and accidental folding of the sleeping basket is avoided. When the sleeping basket needs to be folded, the pull rope (or carrying strap) is pulled out of the plug hole on the guide rail 1 through the pull rope (or carrying strap), so that the sliding member 4 can move along the guide rail 1, and the first orientation first surrounding rod 21, the first orientation second surrounding rod 22, the second orientation first surrounding rod 51, and the second orientation second surrounding rod 52 can be synchronously pivoted towards the guide rail 1 until the sleeping basket is folded to a flat state.

[0241] On the basis of the above structure, the sleeping basket in some embodiments omits the sliding member 4 and the guide rail 1, and when the sleeping basket is folded, the first inclined support rod 61 and the second inclined support rod 62 of the inclined support rod mechanism on the two sides can form a quadrilateral structure with the first surrounding rod and the second surrounding rod on the same side, so that the first surrounding rod assembly and the second surrounding rod assembly can be synchronously folded, the folding operation steps are simplified, and the user's use experience is improved. Further, only one side can be provided with the above-mentioned inclined support rod mechanism, and the first surrounding rod and the second surrounding rod on the same side are synchronously folded through the inclined support rod mechanism when the sleeping basket is folded.

[0242] Now, the sleeping basket according to another embodiment of the present disclosure will be further described in detail in combination with FIGS. B1 to B14. Unless otherwise specified, the drawings in this section are described in combination with one or more of FIGS. B1 to B14. In the drawings of FIGS.

[0246] It should be understood that in the sleeping basket shown in Figures B1-B14, the vertical rod 7 and the fixed seat 1 correspond to the first support and the second support of the support device respectively; the surrounding rod assembly 6 corresponds to the frame device, and the first surrounding rod 61 and the second surrounding rod 62 correspond to the first frame and the second frame respectively; the first frame 2 and the second frame 3 correspond to the first bearing and the second bearing of the bearing device respectively; one side of the support device in the sleeping basket is provided with a first inclined support rod mechanism, and the other side is provided with a second inclined support rod mechanism, the two second support rods 40 correspond to the two first inclined support rods in the first inclined support rod mechanism, and the first support rod 30 corresponds to the second inclined support rod in the second inclined support rod mechanism. The present embodiment will be described in detail below in combination with the related drawings.

[0247] As shown in Figures B1-B14, the present embodiment provides a sleeping basket, which can simplify the folding operation steps of the sleeping basket and improve the user experience. The sleeping basket comprises a fixed seat 1, a first frame 2, a second frame 3, and a first locking structure 4.

[0248] The first enclosure 2 and the second enclosure 3 can be relatively close and expanded, and one end of the first enclosure 2 and the second enclosure 3 close to each other is rotatably connected to the fixed seat 1. The first locking structure 4 is arranged between the first enclosure 2 and the fixed seat 1, and can lock the first enclosure 2 and the fixed seat 1. When the second enclosure 3 rotates relative to the fixed seat 1, the first locking structure 4 can be unlocked to enable the first enclosure 2 to rotate relative to the fixed seat 1 and close to the second enclosure 3.

[0249] The sleeping basket provided in the embodiment can be folded and stored by first rotating the second enclosure 3. The second enclosure 3 rotates relative to the fixed seat 1, and at the same time, the first locking structure 4 is triggered to be unlocked. When the second enclosure 3 is rotated and folded in place, the first locking structure 4 is unlocked, and then the limiting between the first enclosure 2 and the fixed seat 1 is released, so that the first enclosure 2 can rotate relative to the fixed seat 1. At this time, only the first enclosure 2 needs to be rotated and folded, and it is close to the second enclosure 3, so that the folding of the sleeping basket can be completed. The first locking structure 4 does not need to be unlocked separately, thereby simplifying the folding operation steps of the sleeping basket, improving the convenience of folding and storing the sleeping basket for the user, and improving the user experience. In addition, when the second enclosure 3 is initially rotated, the first enclosure 2 is maintained in a locked state, rather than being rotated synchronously with the second enclosure 3. Distributed folding can reduce the harm to the baby in the sleeping basket when misoperation occurs.

[0250] Optionally, referring to FIGS. 1 and 2, the first enclosure 2 and the second enclosure 3 are both surrounding plate structures. The first enclosure 2 and the second enclosure 3 are located at the bottom of the sleeping basket and serve as a load bearing function. Further, the bottom of the first enclosure 2 and the second enclosure 3 is provided with a support leg 23 for supporting the entire sleeping basket, so that the sleeping basket can be stably placed.

[0251] In other embodiments, the first enclosure 2 and the second enclosure 3 can also be frame structures.

[0252] Referring to FIGS. B3 and B4, the second joint seat 31 is arranged at one end of the second frame 3 connected with the fixed seat 1, and the second locking structure 5 is arranged between the second joint seat 31 and the fixed seat 1, and is used for locking the second joint seat 31 and the fixed seat 1. The first locking structure 4 has a first locking position and a first unlocking position, and the second locking structure 5 has a second locking position and a second unlocking position. When the second locking structure 5 is in the second locking position, the second frame 3 is in a locked state with the fixed seat 1, and the second frame 3 cannot rotate around the fixed seat 1. When the second locking structure 5 is in the second unlocking position, the second frame 3 is in an unlocked state with the fixed seat 1, and the second frame 3 can rotate around the fixed seat 1. When the second locking structure 5 is in the second locking position, the first locking structure 4 is in the first locking position. After the second locking structure 5 is switched to the second unlocking position, the first locking structure 4 is switched to the first unlocking position. In this way, the second frame 3 and the first frame 2 can be unlocked in sequence, and the rotation of the first frame 2 and the second frame 3 relative to the fixed seat 1 does not interfere with each other, thereby improving the operation convenience when the sleeping basket is folded.

[0253] Referring to FIGS. B3, B4 and B5, the first joint seat 21 is arranged at one end of the first frame 2 connected with the fixed seat 1, and the first locking structure 4 includes the first locking block 41 movably arranged in the first joint seat 21 in a preset direction. The second joint seat 31 can act on the first locking block 41 at least partially. The fixed seat 1 is provided with the first locking groove 111 capable of being clamped with the first locking block 41. When the second frame 3 rotates, the second joint seat 31 can drive the first locking block 41 to be separated from the first locking groove 111. As shown in FIGS. B8 and B9, when the first locking structure 4 is in the first locking position, the first locking block 41 is clamped with the first locking groove 111, thereby limiting the rotation of the first joint seat 21 relative to the fixed seat 1, that is, limiting the rotation of the first frame 2 relative to the fixed seat 1. After the second locking structure 5 is unlocked, in the process of rotating and folding the second frame 3, the second joint seat 31 rotates relative to the fixed seat 1, and at the same time, the second joint seat 31 applies a force to the first locking block 41, thereby driving the first locking block 41 to move in the preset direction and separate from the first locking groove 111, so as to unlock the first locking structure 4.

[0254] In the embodiment, the preset direction is the diameter direction of the first joint seat 21. Specifically, in FIG. B4, the preset direction is the X direction.

[0255] Referring to FIGS. B10 and B11, the second joint seat 31 is provided with the guide groove 311, and the first locking block 41 is located in the guide groove 311 at least partially. When the second frame 3 rotates relative to the fixed seat 1, the groove wall of the guide groove 311 can push the first locking block 41 to move towards the first unlocking position. That is, when the second frame 3 rotates relative to the fixed seat 1, the power of the first joint seat 21 can be transmitted to the first locking block 41 through the guide groove 311, so that the first locking block 41 moves in the preset direction and moves towards the first unlocking position.

[0256] Optionally, referring to FIG. B11, the guide slot 311 comprises a first slot segment 3111 and a second slot segment 3112 connected in sequence, and both the first slot segment 3111 and the second slot segment 3112 extend in an arc shape, the center of the arc of the first slot segment 3111 is the rotation center of the first joint seat 21, and the center of the arc of the second slot segment 3112 is eccentric to the rotation center of the first joint seat 21. In this way, when the second joint seat 31 is not rotated, the part of the first lock block 41 in contact with the guide slot 311 is located in the first slot segment 3111, at this time, the first slot segment 3111 does not exert force on the first lock block 41, so that the first lock block 41 can be kept in the first locking position. During the rotation of the second frame 3, the slot wall of the second slot segment 3112 can exert an eccentric force on the first lock block 41 when it is in contact with the first lock block 41, thereby driving the first lock block 41 to move in a preset direction, achieving the rotation of the second joint seat 31 while unlocking the first locking structure 4.

[0257] Referring to FIGS. B8 and B9, the first locking structure 4 further comprises a first elastic member 42 arranged between the first lock block 41 and the first joint seat 21, and the first lock block 41 can move in a preset direction towards the first locking position under the elastic force of the first elastic member 42. Specifically, referring to the orientation in FIG. B9, when the second frame 3 is rotated and folded, the second joint seat 31 rotates relative to the fixed seat 1, the first lock block 41 moves towards the lower left corner of FIG. B9, and at the same time, the first elastic member 42 is compressed, and the first elastic member 42 accumulates elastic potential energy. When the second frame 3 is unfolded, the force exerted by the second joint seat 31 on the first lock block 41 is gradually removed, the first elastic member 42 releases the elastic potential energy, and drives the first lock block 41 to move towards the upper right corner of FIG. B9 until the first lock block 41 is engaged with the first lock slot 111.

[0258] The arrangement of the first elastic member 42 can automatically switch the first lock block 41 to the first locking position, and the first lock block 41 can be stably kept in the first locking position under the elastic force of the first elastic member 42, thereby ensuring the stability of the sleeping basket after unfolding. Exemplarily, the first elastic member 42 is a spring.

[0259] Optionally, the first lock block 41 is provided with a first positioning slot 415, the first sliding slot is provided with a second positioning slot in communication therewith, one end of the first elastic member is inserted into the first positioning slot 415, and the other end is inserted into the second positioning slot, thereby ensuring that the first elastic member 41 stably extends and contracts in a preset direction.

[0260] Optionally, referring to FIGS. B4, B5 and B9, the first lock block 41 is provided with a limiting protrusion 412, and the limiting protrusion 412 can be clamped in the first lock slot 111 to limit the first lock block 41 in the first locking position.

[0261] Referring to FIG. B4, FIG. B5, FIG. B6 and FIG. B7, the second locking structure 5 comprises a second locking block 51 movably arranged on the second joint base 31 along a preset direction, a joint base locking slot adapted to the second locking block 51 can be arranged on the first joint base 21, the relative rotation between the second joint base 31 and the first joint base 21 is locked when the second locking block 51 is positioned in the joint base locking slot, and the second joint base 31 can rotate relative to the first joint base 21 when the second locking block 51 is disengaged from the joint base locking slot. The first joint base 21 is locked on the fixed base 11 by the first locking block 41, and the first joint base 21 cannot rotate relative to the fixed base 11, and the first locking block 41 can be moved towards the unlocking position after the second joint base 31 is rotated to a certain angle, so as to release the locking relationship between the first joint base 21 and the fixed base 11, and the two can rotate relative to each other.

[0262] Referring to FIG. B2 and combining with FIG. B10, in order to facilitate the unlocking of the second locking block 5, an unlocking operation part 9 is arranged on the sleeping basket, the unlocking operation part 9 is connected with the second locking structure 5 through a transmission member 10, and the unlocking operation part 9 is configured to drive the transmission member 10 to unlock the second locking structure 5 under the action of external force. When the user folds the sleeping basket, the second locking structure 5 can be unlocked only by applying force to the unlocking operation part 9, and then the second surrounding frame 3 is rotated and folded to unlock the first locking structure 4, and after the first locking structure 4 is unlocked, the first surrounding frame 2 is rotated and folded, and the folding of the sleeping basket is completed.

[0263] In the embodiment, the transmission member 10 is exemplarily a traction rope, one end of the traction rope is connected with the unlocking operation part 9, and the other end is connected with the second locking block 51 of the second locking structure 5, and the unlocking operation part 9 is rotationally arranged on the first surrounding frame 2 or the second surrounding frame 3, when the unlocking operation part 9 is pulled, the traction rope is tensioned to pull the second locking block 51 to move towards the second unlocking position.

[0264] In the above embodiment, the second locking block 51 is directly locked on the first joint base 21, and in other embodiments, the second locking block 51 can also be locked on the first locking block 41, the first locking block 41 moves along the radial direction of the first joint base 21 to move between the locking position and the unlocking position, and the first locking block 41 cannot rotate relative to the first joint base 21 along the circumferential direction, so that when the second locking block 51 is locked on the first locking block 41, the effect is equivalent to being locked on the first joint base 21. It should be noted that the locking here refers to locking the relative rotation of the two.

[0265] Specifically, in the second locking position, the second locking block 51 is locked with the first locking block 41. At this time, the first locking block 41 and the second locking block 51 restrict each other, so that the first locking structure 4 and the second locking structure 5 are both in the locked state, and the first surrounding frame 2 and the second surrounding frame 3 cannot rotate relative to the fixed seat 1. In the second unlocking position, the second locking block 51 is disengaged from the first locking block 41. At this time, the second locking structure 5 is unlocked, the limitation of the first locking structure 4 is removed, and the second surrounding frame 3 can rotate relative to the fixed seat 1, realizing the rotation of the second surrounding frame 3 while driving the first locking structure 4 to be unlocked.

[0266] Specifically, referring to FIGS. B4, B5, B6 and B7, the first locking block 41 is provided with a first protruding portion 411 protruding towards the second locking block 51, and the second locking block 51 is provided with a second protruding portion 511 protruding towards the first locking block 41. As shown in FIGS. B10 and B11, in the second locking position, the second protruding portion 511 is clamped with the first protruding portion 411, so that the first locking block 41 is locked with the second locking block 51. In this embodiment, the second protruding portion 511 is provided with a clamping groove 5111, and when the second locking block 51 is in the second locking position, the first protruding portion 411 is clamped in the clamping groove 5111, thereby limiting the rotation of the second joint seat 31 of the second surrounding frame 3 relative to the fixed seat 1. Referring to the orientation in FIG. B11, when the second locking block 51 is driven to move to the lower left corner, the clamping groove 5111 on the second protruding portion 511 gradually disengages from the first protruding portion 411, thereby realizing the unlocking of the second locking block 51.

[0267] Optionally, referring to FIG. B11, the first protruding portion 411 is located in the guide groove 311 of the second joint seat 31, and when the second joint seat 31 rotates, an acting force is applied to the first protruding portion 411, thereby driving the first locking block 41 to move towards the first unlocking position. Further, the side of the first protruding portion 411 in contact with the guide groove 311 is an arc-shaped convex surface, and when the second joint seat 31 rotates, the groove wall of the guide groove 311 and the arc-shaped convex surface slide together, which can reduce the rotation resistance of the second surrounding frame 3 and improve the smoothness during folding and unfolding of the sleeping basket.

[0268] Optionally, referring to FIGS. B4 and B6, the second locking structure 5 further comprises a second elastic member 52 arranged between the second locking block 51 and the second joint seat 31, and the second locking block 51 can move along a preset direction towards the second locking position under the elastic force of the second elastic member 52. Specifically, when the second locking block 51 is driven to move towards the second unlocking position under the action of an external force, the second locking block 51 extrudes the second elastic member 52 to accumulate elastic potential energy of the second elastic member 52. When the external force is removed, the second elastic member 52 releases the elastic potential energy, thereby driving the second locking block 51 to move towards the second locking position until the clamping groove 5111 of the second protruding portion 511 is clamped with the first protruding portion 411 of the first locking block 41.

[0269] The second elastic member 52 is arranged to enable the second lock block 51 to automatically switch to the second locking position, and the second lock block 51 is stably kept in the second locking position under the elastic force of the second elastic member 52, thereby ensuring the stability of the unfolded sleeping basket. The second elastic member 52 is exemplarily a spring.

[0270] Referring to FIGS. B4, B7 and B12, the second lock block 51 is provided with a positioning column 514 protruding therefrom, the second joint seat 31 is provided with a limiting groove, one end of the second elastic member 52 is sleeved on the positioning column 514, and the other end is inserted into the limiting groove, so that the second elastic member 51 can always stretch and contract in a preset direction, thereby improving the stability of stretching and contraction.

[0271] Optionally, the first joint seat 21 is provided with a first sliding groove (not shown in the drawings) extending in a preset direction, the first sliding groove is arranged to extend in the radial direction of the first joint seat 21, so that the first joint seat 21 can slide in the radial direction of the first joint seat 21. The first lock block 41 is slidingly arranged in the first sliding groove. The first sliding groove can limit the movement direction of the first lock block 41, thereby ensuring that the first lock block 41 can accurately switch between the first locking position and the first unlocking position.

[0272] Referring to FIGS. B4, B5, B8 and B9, the first joint seat 21 is provided with a first cover plate 22, the first cover plate 22 can at least partially cover the first lock block 41 in the first sliding groove, thereby improving the sliding stability of the first lock block 41 in the first sliding groove. The first cover plate 22 is made of steel and is fixedly arranged on the first joint seat 21, thereby enhancing the structural stability of the first joint seat 21.

[0273] Further, the first cover plate 22 is provided with a first guide groove 222, and the first lock block 41 is provided with a first guide protrusion 413, the first guide protrusion 413 and the first guide groove 222 are slidingly matched in a preset direction, thereby further limiting the movement direction of the first lock block 41 and improving the movement accuracy of the first lock block 41.

[0274] Referring to FIG. B4, the first joint seat 21 is provided with a first avoiding groove 211 corresponding to the first protruding portion 411, and the first protruding portion 411 is inserted into the first avoiding groove 211 and can move in a preset direction in the first avoiding groove 211. The first avoiding groove 211 can prevent the first joint seat 21 from interfering with the movement of the first lock block 41 between the first locking position and the first unlocking position, and can enable the first protruding portion 411 to pass through the first joint seat 21 and be connected with the second protruding portion 511.

[0275] Referring to FIG. B4 and FIG.

[0288] Referring to FIGS. B4 and B6, the third locking structure 8 for locking the standing rod 7 is arranged between the standing rod 7 and the fixed seat 1, and the second locking structure 5 can drive the third locking structure 8 to be unlocked during the unlocking process. That is, the second locking structure 5 can be unlocked synchronously with the third locking structure 8 during the unlocking process, so that the second frame 3 and the standing rod 7 can be unlocked synchronously, and the second frame 3 and the second surrounding rod 62 can be rotated and folded synchronously, while the standing rod 7 is retracted into the first accommodating cavity 121 of the fixed seat 1.

[0289] Referring to FIGS. B4, B6, B13 and B14, the third locking structure 8 comprises a locking hook 81 and a third elastic member 82, the locking hook 81 is rotatably arranged in the fixed seat 1, the standing rod 7 is provided with a second locking groove 71, the first end of the locking hook 81 can be hooked in the second locking groove 71, and the second locking structure 5 can be in contact with the second end of the locking hook 81 during the unlocking process to drive the locking hook 81 to rotate in a direction away from the second locking groove 71. One end of the third elastic member 82 is connected with the locking hook 81, and the other end is connected with the fixed seat 1, and the locking hook 81 can be rotated in a direction hooked with the second locking groove 71 under the elastic force of the third elastic member 82.

[0290] Specifically, as shown in FIG. B3, FIG. B4 and FIG. B6, when the sleeping basket is in the unfolded state, the second locking structure 5 is in the second locking position, the locking hook 81 is hooked on the second lock slot 71, and the stand rod 7 is locked. When an external force is applied to the second lock block 51 of the second locking structure 5 through the unlocking operation part 9, the second lock block 51 moves towards the second unlocking position, the second lock block 51 can contact the second end of the locking hook 81, and the locking hook 81 is driven to be disengaged from the second lock slot 71, so that the second lock block 51 is unlocked at the same time as the locking hook 81 is unlocked. During the unlocking of the locking hook 81, the third elastic member 82 is compressed and stored. When the stand rod 7 is extended from the first accommodating cavity 121 of the fixing seat 1 again, the stand rod 7 slides to the position where the second lock slot 71 is opposite to the first end of the locking hook 81, and under the action of the elastic force of the third elastic member 82, the first end of the locking hook 81 rotates towards the second lock slot 71 and is hooked on the second lock slot 71, so as to lock the stand rod 7. Exemplarily, the third elastic member 82 is a spring.

[0291] In this embodiment, the second seat body 12 is provided with a third accommodating cavity which is in communication with the first accommodating cavity 121, and the locking hook 81 is located in the third accommodating cavity. The middle position of the locking hook 81 is rotationally connected to the second seat body 12 through a rotating shaft, and the first end of the locking hook 81 can be hooked on the second lock slot 71 on the stand rod 7 through the position where the first accommodating cavity 121 and the third accommodating cavity are in communication.

[0292] Referring to FIG. B4 and FIG. B6, the first end of the locking hook 81 is provided with a hooking part 811 which can be hooked in the second lock slot 71 to lock the stand rod 7, so that the stand rod 7 remains in the position of extending out of the first accommodating cavity 121, thereby ensuring the stability of the unfolded sleeping basket. The second end of the locking hook 81 is provided with a triggering part 812, and the second lock block 51 is provided with a pushing part 512. When the second lock block 51 is in the second locking position, the pushing part 512 is located above the triggering part 812 and has no force acting on the triggering part 812. When the second lock block 51 is driven to move along the preset direction towards the second unlocking position, the pushing part 512 will apply pressure to the triggering part 812 after contacting the triggering part 812, so that the first end of the locking hook 81 rotates towards the direction of disengaging from the second lock slot 71, thereby unlocking the stand rod 7.

[0293] Referring to FIG. B6, the second cover plate 32 is provided with a third avoiding slot 321 corresponding to the pushing part 512, and the pushing part 512 is arranged in the third avoiding slot 321 and can move in the third avoiding slot 321 along the preset direction. The third avoiding slot 321 can prevent the second cover plate 32 from interfering with the movement of the second lock block 51 between the second locking position and the second unlocking position, and can also make the pushing part 512 extend out of the second sliding slot 312 to contact the locking hook 81.

[0294] Referring to FIGS. B13 and B14, the second seat body 12 of the fixed seat 1 is provided with an arc-shaped guide groove 122 in communication with the third accommodating cavity, and the second locking block 51 is arranged in the arc-shaped guide groove 122. When the second surrounding frame 3 is rotated to be folded, the second joint seat 31 is rotated relative to the second seat body 12, and the second locking block 51 can slide in the arc-shaped guide groove 122 to avoid interference, thereby ensuring smooth rotation of the second surrounding frame 3.

[0295] Optionally, referring to FIG. B1, the sleeping basket further comprises a first supporting rod 30 and a second supporting rod 40 arranged on opposite sides of the vertical rod 7. One end of the first supporting rod 30 is rotationally connected with the first surrounding frame 2, and the other end is rotationally connected with the surrounding rod assembly 6. One end of the second supporting rod 40 is rotationally connected with the second surrounding frame 3, and the other end is rotationally connected with the surrounding rod assembly 6. The first supporting rod 30 and the second supporting rod 40 support the surrounding frame assembly, so that the sleeping basket can be stably maintained in an unfolded state, and the structure is stable and reliable. Further, when the sleeping basket is unfolded, the first supporting rod 30 and the second supporting rod 40 are both arranged obliquely to improve the support stability.

[0296] Optionally, referring to FIGS. B1 and B3, the surrounding rod assembly 6 comprises a first surrounding rod 61 and a second surrounding rod 62 rotationally connected. The first surrounding rod 61 and the second surrounding rod 62 are both in U shape. The first surrounding rod 61 is rotationally connected with a first supporting rod 30 on each side in the width direction, thereby improving the connection stability between the first surrounding frame 2 and the first surrounding rod 61.

[0297] Continuously referring to FIGS. B1 and B3, the second surrounding rod 62 is rotationally connected with a second supporting rod 40 on each side in the width direction. At least one side is provided with two second supporting rods 40, and the two second supporting rods 40 form a parallelogram with the second surrounding frame 3 and the second surrounding rod 62. When the second surrounding frame 3 is rotated to be folded, the second surrounding frame 3 can exert a force on the second surrounding rod 62 through the two second supporting rods 40, so that the second surrounding rod 62 is synchronously rotated inward with the second surrounding frame 3, and the second surrounding rod 62 does not need to be folded separately. The sleeping basket is folded more simply. The two second supporting rods 40 are connected between the second surrounding frame 3 and the second surrounding rod 62, so that the second surrounding rod 62 can respond in time when the second surrounding frame 3 is rotated, thereby realizing synchronous rotation and folding of the second surrounding frame 3 and the second surrounding rod 62. In the prior art, a single rod is generally used to connect the second surrounding frame 3 and the second surrounding rod 62. The single rod connection cannot effectively realize synchronous rotation of the second surrounding frame 3 and the second surrounding rod 62, and often causes the second surrounding rod 62 to lag behind after the second surrounding frame 3 is rotated, thereby causing folding to be blocked.

[0298] In this embodiment, the second surrounding rod 62 is rotationally connected with two second supporting rods 40 on each side in the width direction, thereby improving the synchronism of the second surrounding frame 3 and the second surrounding rod 62, and improving the support stability therebetween.

[0299] Optionally, referring to FIG. B1 and FIG. B2, the sleeping basket further comprises a handle 50 rotatably connected with the surrounding rod assembly 6, the handle 50 having a storage position and a use position, in the storage position, the handle 50 is rotated to be close to the surrounding rod assembly 6, reducing the volume of the sleeping basket after folding; in the use position, the free end of the handle 50 is away from the surrounding rod assembly 6, facilitating the user to take the sleeping basket through the handle 50.

[0300] The embodiment also provides a carrier comprising a support frame and the sleeping basket as described above, the sleeping basket being detachably mounted on the support frame. Wherein, the support frame can be a vehicle frame, and the sleeping basket is mounted on the vehicle frame to form a stroller, facilitating the user to push the stroller. In other embodiments, the support frame can also be a skeleton of a child bed, etc.

[0301] Optionally, the first seat 1 is provided with a first plug-in structure, and the support frame is provided with a second plug-in structure, the first plug-in structure and the second plug-in structure being plugged to realize the detachable mounting of the sleeping basket and the support frame.

[0302] Exemplarily, referring to FIG. B1 and FIG. B2, the first plug-in structure comprises a slot 112 provided on the first seat body 11 of the first seat 1, and the second plug-in structure is a plug tongue provided on the support frame, the plug tongue being capable of being plugged into the slot 112.

[0303] The carrier provided by the embodiment makes the sleeping basket both be used alone and be used in cooperation with the support frame, so that the different use requirements of the user can be met, and the flexibility is high.

[0304] Now, the sleeping basket according to still another embodiment of the present disclosure will be further described in detail in combination with FIG. C1 to FIG. C12. Unless otherwise specified, the drawings in this section are described in combination with one or more of FIG. C1 to C12. Wherein, the reference signs of FIG. C1 to C12 are described as follows:

[0306] It should be understood that in the sleeping basket shown in Figures C1-C14, the vertical rod 2 and the connecting seat 1 correspond to the first supporting member and the second supporting member of the supporting device respectively; the first frame assembly 3 corresponds to the frame device, the second frame body 32 and the first frame body 31 correspond to the first frame and the second frame respectively; the fourth frame body 42 and the third frame body 41 correspond to the first supporting member and the second supporting member of the supporting device respectively; one side of the sleeping basket is provided with a first inclined supporting rod mechanism, and the other side is provided with a second inclined supporting rod mechanism, wherein the two first supporting rods 51 correspond to the two first inclined supporting rods of the first inclined supporting rod mechanism, and the second supporting rod 52 corresponds to the second inclined supporting rod of the second inclined supporting rod mechanism.

[0307] The present embodiment will be described in detail below in conjunction with the relevant drawings. As shown in Figures C1 and C2, the present embodiment provides a sleeping basket having a folded state and an unfolded state, which can solve the problem of complicated operation when unfolding the sleeping basket and improve the user's experience. The sleeping basket comprises a connecting seat 1, a vertical rod 2, a first frame assembly 3, a second frame assembly 4, and a support assembly 5.

[0308] Wherein, referring to Fig. C1, Fig. C2, Fig. C3 and Fig. C4, the stand 2 is in sliding connection with the connecting base 1 and has a supporting position and a storage position, when the sleeping basket is in the unfolded state, the stand 2 is in the supporting position; when the sleeping basket is in the folded state, the stand 2 is in the storage position. The first frame assembly 3 comprises a first frame body 31 and a second frame body 32 which are in rotational connection with the stand 2; the second frame assembly 4 comprises a third frame body 41 and a fourth frame body 42 which are in rotational connection with the connecting base 1. The supporting assembly 5 comprises a first supporting rod 51, both ends of the first supporting rod 51 are in movable connection with the first frame body 31 and the third frame body 41 respectively, and the third frame body 41 is arranged with two first supporting rods 51 on at least one side in the first direction. When the third frame body 41 is unfolded relative to the connecting base 1, the two first supporting rods 51 can drive the first frame body 31 to be unfolded synchronously in the second direction, and make the stand 2 slide synchronously to the supporting position relative to the connecting base 1, and the first direction and the second direction form an included angle.

[0309] The sleeping basket provided by the embodiment is arranged with two first supporting rods 51 between the third frame body 41 and the first frame body 31 on at least one side in the first direction, so that the two supporting rods and the third frame body 41 and the first frame body 31 form a quadrilateral. When the sleeping basket is switched from the folded state to the unfolded state, the third frame body 41 is unfolded relative to the connecting base 1, that is, during the unfolding process of the third frame body 41 relative to the fourth frame body 42, the quadrilateral structure makes the third frame body 41 drive the first frame body 31 to be unfolded synchronously relative to the second frame body 32, so as to realize the synchronous unfolding of the first frame body 31 and the third frame body 41.

[0310] Meanwhile, since the first frame body 31 and the second frame body 32 are in rotational connection with the stand 2, and the stand 2 is in sliding connection with the connecting base 1, the first frame body 31 can drive the stand 2 to slide synchronously relative to the connecting base 1 during the unfolding process of the first frame body 31, so as to realize the synchronous sliding of the stand 2 to the supporting position when the first frame body 31 and the third frame body 41 are unfolded to the position, thereby ensuring that the stand 2, the first frame body 31 and the third frame body 41 can be locked synchronously, so that the sleeping basket can be accurately switched to the unfolded state and kept in the unfolded state.

[0311] The structure design of the sleeping basket makes the user not need to separately unfold the first frame body 31 and the third frame body 41 when unfolding the sleeping basket, and not need to separately stretch the stand 2 to the supporting position, so as to simplify the operation steps when unfolding the sleeping basket and improve the user experience.

[0312] In the embodiment, referring to Fig. C1 and Fig. C3, the first direction is the X direction, which is the width direction of the sleeping basket; the second direction is the Y direction, which is the length direction of the sleeping basket. In other embodiments, the first direction and the second direction can be determined according to the actual situation, and are not limited to the X direction and the Y direction shown in the figures.

[0313] Optionally, referring to FIG. C1 and FIG. C3, the third frame body 41 is arranged with the first support rod 51 on both sides in the first direction. In this way, both sides of the first frame body 31 and the third frame body 41 in the first direction can be effectively supported, improving the support stability of the sleeping basket after unfolding.

[0314] Further, the third frame body 41 is arranged with two first support rods 51 on both sides, which can make the third frame body 41 and the first frame body 31 better synchronized when unfolding, and further improve the structural stability of the sleeping basket.

[0315] Of course, in other embodiments, two first support rods 51 can be arranged on one side of the sleeping basket in the first direction, and one first support rod 51 can be arranged on the other side.

[0316] Optionally, the two first support rods 51 on the same side form a parallelogram with the first frame body 31 and the third frame body 41. That is, the two first support rods 51 are arranged in parallel, and the structure of the parallelogram makes the third frame body 41 drive the first frame body 31 to unfold or fold synchronously relative to the second frame body 32, so that the rotation angles of the first frame body 31 and the third frame body 41 are consistent, which can prevent the first frame body 31 from deflecting relative to the third frame body 41 when the third frame body 41 is rotating to fold or unfold, and ensure the synchronization of the unfolding and folding of the standing pole 2, the first frame body 31 and the third frame body 41.

[0317] Referring to FIG. C1, when the sleeping basket is in an unfolded state, the first support rod 51 is arranged obliquely relative to the first frame body 31 and the third frame body 41. In this way, the first support rod 51, the first frame body 31 and the standing pole 2 can form a stable triangular support structure, which is more stable.

[0318] Optionally, the first end of the first support rod 51 is rotationally connected with the first frame body 31, and the second end of the first support rod 51 is rotationally connected with the third frame body 41. During the unfolding and folding of the third frame body 41, the two ends of the first support rod 51 adaptively rotate relative to the first frame body 31 and the third frame body 41, ensuring that the first frame body 31 and the third frame body 41 can be smoothly folded and unfolded. In other embodiments, the first support rod 51 can be slidingly connected or slidingly and rotationally connected with the first frame body 31 and the third frame body 41, as long as it does not interfere.

[0319] Optionally, the connecting seat 1 is provided with a sliding cavity 121, and the standing pole 2 is slidingly arranged in the sliding cavity 121 and can be at least partially hidden in the sliding cavity 121. The arrangement of the sliding cavity 121 enables the first frame body 31 and the second frame body 32 to move close to each other after the sleeping basket is folded, and the standing pole 2 slides back into the sliding cavity 121, thereby hiding at least part of the standing pole 2, reducing the size of the sleeping basket after folding, and facilitating storage and carrying.

[0320] In this embodiment, referring to FIG. C1 and FIG. C2, after the sleeping basket is switched to the folded state, the sliding end of the stand rod 2 does not protrude from the connecting seat 1. That is, the stand rod 2 can be hidden in the sliding cavity 121 except the part connected with the first frame 31 and the second frame 32, thereby minimizing the volume of the sleeping basket after folding and making the external appearance neat and beautiful after folding.

[0321] Of course, in other embodiments, the sliding cavity 121 can also be designed to pass through the connecting seat 1 in the third direction, and part of the stand rod 2 penetrates out of the sliding cavity 121 after the sleeping basket is folded. Referring to the orientation in FIG. C1 and FIG. C3, the third direction is the height direction of the sleeping basket.

[0322] In this embodiment, referring to FIG. C1 and FIG. C2, the first frame 31 and the second frame 32 are folded upward and close to each other, and the third frame 41 and the fourth frame 42 are also folded upward and close to each other to achieve the folding of the sleeping basket, and the stand rod 2 slides downward relative to the connecting seat 1.

[0323] In other embodiments, the first frame 31 and the second frame 32 and the third frame 41 and the fourth frame 42 can also be designed to be folded downward and close to each other to achieve the folding of the sleeping basket, and at this time, the connecting seat 1 can be arranged between the first frame 31 and the second frame 32, and the stand rod 2 slides upward relative to the connecting seat 1.

[0324] Optionally, referring to FIG. C1 and FIG. C3, the sleeping basket further comprises a second support rod 52, the first end of the second support rod 52 is rotationally connected with the second frame 32, and the second end of the second support rod 52 is rotationally connected with the fourth frame 42. The second support rod 52 supports the second frame 32 and the fourth frame 42, so that the sleeping basket can be stably maintained in the unfolded state, and the structure is stable and reliable. In this embodiment, when the sleeping basket is in the unfolded state, the second support rod 52 is arranged obliquely to improve the support stability.

[0325] Optionally, in the first direction, one second support rod 52 is arranged on each side of the second frame 32 and the fourth frame 42.

[0326] In other embodiments, two second support rods 52 can also be arranged on both sides of the second frame 32 and the fourth frame 42 in the first direction, so that the fourth frame 42 and the second frame 32 can be unfolded and folded synchronously, and the convenience of unfolding and folding the sleeping basket is further improved.

[0327] When folding the sleeping basket, the third frame 41 drives the first frame 31 to fold synchronously through the first support rod 51, at the same time, the stand rod 2 slides towards the storage position relative to the connecting seat 1, and the sliding of the stand rod 2 forces the second frame 32 to close to the first frame 31, and the second frame 32 further pulls the fourth frame 42 to close to the third frame 41 through the second support rod 52.

[0328] When the sleeping basket is unfolded, the third frame body 41 is driven by the first supporting rod 51 to drive the first frame body 31 to unfold synchronously, and meanwhile, the vertical rod 2 slides relative to the connecting seat 1 to the supporting position, and the vertical rod 2 drives the second frame body 32 to unfold relative to the first frame body 31, and the second frame body 32 drives the fourth frame body 42 to unfold relative to the third frame body 41 through the second supporting rod 52.

[0329] Optionally, the connecting seat 1 is arranged on both sides of the third frame body 41 and the third frame body 41 in the width direction, and correspondingly, the vertical rod 2 is provided with two ends, and the two ends of the two vertical rods 2 are slidably connected with the two connecting seats 1 one by one, and the other ends of the two vertical rods 2 are rotatably connected with the first frame body 31 and the second frame body 32, thereby improving the structural stability of the sleeping basket.

[0330] Optionally, referring to FIGS. C1 and C2, the first frame body 31 and the second frame body 32 are both surrounding rod structures, and are located at the top of the sleeping basket (when the sleeping basket is in the unfolded state); the third frame body 41 and the fourth frame body 42 are both surrounding plate structures, and are located at the bottom of the sleeping basket, and serve as a bearing function. Further, the bottom of the third frame body 41 and the fourth frame body 42 is provided with a supporting leg 413, which is used to support the entire sleeping basket, so that the sleeping basket can be stably placed.

[0331] In other embodiments, the third frame body 41 and the fourth frame body 42 can also be frame structures.

[0332] Optionally, referring to FIGS. C3 and C4, the sleeping basket further comprises a first locking structure 6 arranged between the vertical rod 2 and the connecting seat 1, and a second locking structure 7 arranged between the third frame body 41 and the connecting seat 1, and the second locking structure 7 can at least partially act on the first locking structure 6 to drive the first locking structure 6 to be unlocked during unlocking of the second locking structure 7. That is, the first locking structure 6 can be unlocked synchronously during unlocking of the second locking structure 7, so that the third frame body 41 and the vertical rod 2 are unlocked synchronously, so that the third frame body 41 and the first frame body 31 can be rotated and folded synchronously, and meanwhile, the vertical rod 2 is retracted into the sliding cavity 121 of the connecting seat 1, and is switched to the storage position. When the sleeping basket is unfolded, the first frame body 31 and the third frame body 41 are unfolded to the position, and the second locking structure 7 is locked, and at the same time, the vertical rod 2 slides to the supporting position, and the first locking structure 6 is locked.

[0333] Referring to FIGS. C3, C4, C6 and C7, the first locking structure 6 comprises a locking hook 61 rotatably arranged on the connecting seat 1, and the vertical rod 2 is provided with a locking groove 21, and when the vertical rod 2 is in the supporting position, the locking hook 61 is hooked on the locking groove 21. After the third frame body 41 and the first frame body 31 are unfolded to the position synchronously, the vertical rod 2 slides relative to the connecting seat 1 to the locking groove 21 and the locking hook 61 to hook and lock, so that the vertical rod 2 can be stably kept in the supporting position.

[0334] Referring to FIG. C4, FIG. C5 and FIG. C8, the third frame body 41 is provided with a first joint seat 411 at one end connected with the connecting base 1, and the second locking structure 7 includes a lock block 71 movably arranged in the first joint seat 411 along a preset direction, which can contact the lock hook 61 and drive the lock hook 61 to rotate in a direction away from the lock slot 21 when moving along the preset direction. By driving the lock block 71 to move along the preset direction to unlock the first joint seat 411 and the connecting base 1, the third frame body 41 can be rotated and folded relative to the connecting base 1, and at the same time, the lock block 71 drives the lock hook 61 to rotate and move away from the lock slot 21, realizing synchronous unlocking of the stand 2 and the third frame body 41.

[0335] Referring to FIG. C4 and FIG. C6, the first locking structure 6 further includes a first elastic member 62, one end of which is connected with the lock hook 61 and the other end of which is connected with the connecting base 1, and the lock hook 61 can rotate in a direction of hooking with the lock slot 21 under the elastic force of the first elastic member 62. Specifically, as shown in FIG. C4, FIG. C6 and FIG. C7, when the sleeping basket is in the unfolded state and the second locking structure 7 is in the locked position, the first end of the lock hook 61 is hooked in the lock slot 21, and the stand 2 is locked in the supporting position. When the second locking structure 7 is unlocked, the lock block 71 contacts the second end of the lock hook 61, driving the lock hook 61 to move away from the lock slot 21, realizing unlocking of the lock block 71 at the same time. During the unlocking process of the lock hook 61, the first elastic member 62 is compressed and stored with energy, and when the third frame body 41 is rotated and unfolded relative to the connecting base 1, the stand 2 is extended and slides into the sliding cavity 121 again, and when the third frame body 41 and the first frame body 31 are unfolded to the position, the stand 2 slides to the position where the lock slot 21 is opposite to the first end of the lock hook 61, and under the elastic force of the first elastic member 62, the first end of the lock hook 61 rotates towards the lock slot 21 and is hooked with the lock slot 21, realizing locking of the stand 2. Exemplarily, the first elastic member 62 is a spring.

[0336] Referring to FIG. C4 and FIG. C8, the second locking structure 7 further includes a second elastic member 72 arranged between the lock block 71 and the first joint seat 411, and the lock block 71 can move along the preset direction to the locking position under the elastic force of the second elastic member 72. Specifically, when the lock block 71 is driven to move to the unlocking position under the external force, the lock block 71 presses the second elastic member 72 to store the elastic potential energy of the second elastic member 72. When the external force is removed, the second elastic member 72 releases the elastic potential energy, thereby driving the lock block 71 to move to the locking position.

[0337] The arrangement of the second elastic member 72 can automatically switch the lock block 71 to the locking position, and the lock block 71 can be stably kept in the locking position under the elastic force of the second elastic member 72, ensuring the stability of the sleeping basket after unfolding. Exemplarily, the second elastic member 72 is a spring.

[0338] Referring to FIG. C4, FIG. C5 and FIG. C8, the locking block 71 is provided with a positioning column 714, and the first joint base 411 is provided with a limiting groove (not shown in the figure). One end of the second elastic member 72 is sleeved on the positioning column 714, and the other end is inserted into the limiting groove, so that the second elastic member 72 can always stretch and contract in a preset direction, improving the stability of stretching and contraction.

[0339] Referring to FIG. C1, FIG. C2 and FIG. C8, the sleeping basket is provided with an unlocking operation part 8, which is connected with the second locking structure 7 through a transmission member 9. The unlocking operation part 8 is configured to drive the transmission member 9 to drive the second locking structure 7 to unlock under the action of external force. When the user folds the sleeping basket, the second locking structure 7 can be unlocked only by applying force through the unlocking operation part 8, and then the first locking structure 6 is synchronously unlocked.

[0340] In this embodiment, the transmission member 9 is exemplarily a traction cable. One end of the traction cable is connected with the unlocking operation part 8, and the other end is connected with the locking block 71 of the second locking structure 7. The unlocking operation part 8 is rotationally arranged on the third frame body 41 or the fourth frame body 42. When the unlocking operation part 8 is pulled, the traction cable is tensioned to pull the locking block 71 to move towards the unlocking position.

[0341] Optionally, referring to FIG. C3, FIG. C4 and FIG. C8, the first joint base 411 is provided with a sliding groove 4111 extending in a preset direction, and the locking block 71 is slidingly arranged in the sliding groove 4111. The arrangement of the sliding groove 4111 can limit the movement direction of the locking block 71, so as to ensure that the locking block 71 can accurately switch between the locking position and the unlocking position.

[0342] Referring to FIG. C4, the first joint base 411 is provided with a cover plate 412, which can at least partially cover the locking block 71 in the sliding groove 4111, improving the sliding stability of the locking block 71 in the sliding groove 4111.

[0343] Further, referring to FIG. C4 and FIG. C5, the cover plate 412 is provided with a guide groove 4122, and the locking block 71 is provided with a guide protrusion 713. The guide protrusion 713 and the guide groove 4122 are slidingly matched in a preset direction, which can further limit the movement direction of the locking block 71 and improve the movement accuracy of the locking block 71.

[0344] Referring to FIG. C6 and FIG. C7, the connecting base 1 is provided with a receiving cavity 122, and the locking hook 61 is rotationally arranged in the receiving cavity 122. The receiving cavity 122 provides a space for the rotation of the locking hook 61. Exemplarily, the middle position of the locking hook 61 is rotationally connected with the inner wall of the receiving cavity 122 through a rotating shaft. In this embodiment, the side of the receiving cavity 122 close to the sliding cavity 121 is provided with a through hole communicating the receiving cavity 122 and the sliding cavity 121. The first end of the locking hook 61 can extend into the sliding cavity 121 through the through hole to be hooked with the locking groove 21 on the stand 2.

[0345] Optionally, referring to FIGS. C6 and C7, the connecting seat 1 is provided with a first avoiding slot 123, and when the third frame body 41 rotates relative to the connecting seat 1, the part of the lock block 71 in contact with the lock hook 61 slides in the first avoiding slot 123. The first avoiding slot 123 can prevent the lock block 71 from interfering with the connecting seat 1 during the unfolding and folding of the third frame body 41, and ensure the smoothness of the unfolding and folding of the third frame body 41. In this embodiment, the pushing part 711 of the lock block 71 is located in the first avoiding slot 123. Exemplarily, the first avoiding slot 123 extends in an arc shape to adapt to the rotating track of the lock block 71 along with the first joint seat 411.

[0346] Referring to FIGS. C4 and C7, the first end of the lock hook 61 is provided with a hooking part 611, which can be clamped with the lock slot 21 to lock the stand rod 2, so that the stand rod 2 is stably kept in the supporting position, and the stability of the sleeping basket after unfolding is ensured. The second end of the lock hook 61 is provided with a triggering part 612, and the lock block 71 is provided with a pushing part 711, which can contact the triggering part 612 when the lock block 71 moves in a predetermined direction. Specifically, when the lock block 71 is in the locked position, the pushing part 711 is located above the triggering part 612 and has no force on the triggering part 612. When an external force drives the lock block 71 to move in a predetermined direction towards the unlocked position, the pushing part 711 will exert pressure on the triggering part 612 after contacting the triggering part 612, so that the first end of the lock hook 61 rotates in a direction away from the second lock slot 21, thereby unlocking the stand rod 2.

[0347] Referring to FIG. C4, the cover plate 412 is provided with a second avoiding slot 4121 corresponding to the pushing part 711, and the pushing part 711 is arranged in the second avoiding slot 4121 and can move in a predetermined direction in the second avoiding slot 4121. The second avoiding slot 4121 can prevent the cover plate 412 from interfering with the movement of the lock block 71, and at the same time, the pushing part 711 can extend out of the sliding slot 4111 to contact the lock hook 61.

[0348] Referring to FIGS. C4, C5 and C9, the fourth frame body 42 is provided with a second joint seat 421 at one end connected with the connecting seat 1, and a limiting block is arranged between the second joint seat 421 and the connecting seat 1. The limiting block is provided with a first protruding part 422 protruding towards the lock block 71, and the lock block 71 is provided with a second protruding part 712 protruding towards the limiting block. When the second locking structure 7 is in the locked position, the second protruding part 712 is clamped with the first protruding part 422, so that the lock block 71 is kept in the locked position. In this embodiment, the second protruding part 712 is provided with a clamping slot 7121, and the first protruding part 422 can be clamped in the clamping slot 7121, thereby limiting the rotation of the first joint seat 411 of the third frame body 41 relative to the connecting seat 1.

[0349] Referring to the orientation in FIG. C8, when the lock block 71 is driven to move to the lower left corner, the clamping groove 7121 on the second protruding portion 712 gradually disengages from the first protruding portion 422, thereby achieving unlocking of the lock block 71. In this embodiment, the preset direction is the P direction in FIG. 8.

[0350] Referring to FIGS. C1, C2, C3 and C4, the connecting seat 1 includes a first seat body 11 and a second seat body 12, the first joint seat 411 and the second joint seat 421 are located between the first seat body 11 and the second seat body 12, the second locking structure 7 is arranged between the first joint seat 411 and the second seat body 12, and the first joint seat 411 is rotationally connected with the second joint seat 421.

[0366] It is to be understood that in the bassinet shown in Figures D1-D15, the support device 12 corresponds to a support device, the upper support section 22 and the lower support section correspond to a first support member and a second support member, respectively; the upper frame 11 corresponds to a surrounding frame device, the first frame section 17 and the second frame section 18 correspond to a first frame and a second frame, respectively; the carrier device 10 corresponds to a carrier device, the first carrier section 15 and the second carrier section 16 correspond to a first carrier member and a second carrier member, respectively. The links 13b and 13c correspond to two first diagonal support rods in a first diagonal support rod mechanism; the link 13a corresponds to a second diagonal support rod in a second diagonal support rod mechanism. The present embodiment will be described in detail below with reference to the relevant drawings.

[0367] In the following description, identical reference signs are used for identical and functionally identical parts.

[0368] Figure D1 shows a side view of the bassinet (without soft furnishings and cloth sections). The bassinet comprises a carrier device 10 and an upper frame 11. A support device 12 is located between the carrier device 10 and the upper frame 11. Furthermore, the carrier device 10 and the upper frame 11 are connected to one another by means of links 13a, 13b, 13c. The links 13a, 13b and 13c can generally be any type of coupling device, for example, the links 13a-13c can be designed as (elongate and / or U-shaped) rods, the function of which is primarily to couple the movements of the carrier device 10 and the upper frame 11 (or sections thereof). A handle 14 is also hinged to the upper frame 11 (preferably pivotable).

[0369] The carrier device 10 comprises a first carrier section 15 and a second carrier section 16. The upper frame 11 comprises a first frame section 17 and a second frame section 18. The first carrier section 15 and the second carrier section 16 are hinged (preferably each with a lower hinge on each side) via a lower hinge device 19. The first frame section 17 and the second frame section 18 are hinged via an upper hinge device 20. The upper hinge device 20 can have two upper hinges, one on the left and one on the right.

[0370] The handle 14 is hinged to the upper frame 11 (in particular to the second frame section 18) by means of a handle hinge device 21.

[0371] The support device 12 comprises a lower support section 22 (disc-shaped) and an upper support section 23 (designed as a strut or comprising the same). The upper support section 23 is telescopically movable relative to the lower support section 22 (and vice versa). The area of the lower hinge device 19 is provided with an adapter device 24 (a recess with an open bottom) for mounting the bassinet to a pushchair frame, for example.

[0372] The support device 12 is hinged to the first and second frame sections 17, 18 via the upper hinge device 20; it (in particular the lower support section 22) is also hinged to the first and second carrier sections 15, 16 via the lower hinge device 19.

[0373] The upper hinge arrangement 20 defines a common axis 29 about which the first and second frame segments 17, 18 and the support arrangement 12 can be relatively pivoted (optional). Likewise, the lower hinge arrangement 19 forms a common axis 30 about which the first and second carrier segments 15, 16 and the support arrangement 12 can be relatively pivoted (optional).

[0374] It is also conceivable that the first frame segment 17 and the second frame segment 18 can be pivoted about different axes, for example with an intermediate segment between them which can be moved together with the upper support segment 23 relative to the lower support segment 22 (the upper support segment 23 can be T-shaped). The same applies to the first and second carrier segments 15, 16.

[0375] The upper support segment 23 and the lower support segment 22 can be interchanged in their construction: i.e. the upper support segment 23 is disc-shaped and the lower support segment 22 contains struts (for example one to the left and one to the right).

[0376] In the embodiment shown in Figure D1, the upper end 26 and the lower end 27 of the support arrangement 12 can be close to each other. The axis 29 of the upper hinge arrangement 20 and the axis 30 of the lower hinge arrangement 19 have a distance 31 between them, which can be reduced when the sleeping basket is moved from the use state to the stowed state.

[0377] The sleeping basket lying surface extends from the head end 32 to the foot end 33. Figure D1 shows the use state.

[0378] Figure D2 shows an intermediate state between use and stowage: the first carrier segment 15 is pivoted relative to the second carrier segment 16 and relative to the support arrangement 12; the second carrier segment 16 is not pivoted relative to the support arrangement 12; the first and second frame segments 17, 18 are pivoted relative to each other and relative to the support arrangement 12.

[0379] Figure D3 shows a further intermediate state: the first carrier segment 15, the first frame segment 17 and the second frame segment 18 continue to be pivoted relative to the support arrangement 12, the second carrier segment 16 still not being pivoted.

[0380] Figure D4 is an oblique view of Figure D3.

[0381] Figure D5 shows a further intermediate state: the first carrier segment 15 and the first frame segment 17 are substantially parallel to the support arrangement 12; the second frame segment 18 and the second carrier segment 16 begin to be pivoted away from the support arrangement 12.

[0382] Figure D6 shows the stowed state: the first and second carrier segments 15, 16 and the first and second frame segments 17, 18 are substantially parallel to each other and to the support arrangement 12; the distance 31 between the axes 29 and 30 has been reduced.

[0383] Figure D7 is an oblique view of Figure D6.

[0384] Figure D8 shows a side section of the use state of figure D1 : the axis 30 of the lower hinge device 19 is located above the upper side of the carrier device 12, thus forming a cavity between the first and second carrier segments 15, 16 in the stowed state (figure D6) for accommodating the frame segments, the linkage and the soft shell / sleeping bag.

[0385] Figure D9 is a partial enlargement of figure D8: the upper support segment 23 is partially inserted into the lower support segment 22; both are locked by the locking device 35. The lower support segment 22 is provided with a protrusion facing the upper support segment 23, forming a receptacle. The upper support segment 23 can be pushed further in.

[0386] The locking device 35 (one on each side) comprises a latch 36 and at least one latch receptacle 37, 38; it is also conceivable that two latches correspond to one or two receptacles. At least two locking positions should be provided (distance < 5 cm or < 3 cm). The latch 36 can generally be any type of latch; the latch receptacles 37 and 38 can generally be any type of latch receptacle.

[0387] Figure D10 shows a detailed section: the latch 36 has an engagement section 39, a securing section 40 and a drive section 41, which can be rotated about an axis 42. The pulling element 44, which can be any type of pulling element such as a pull rod or a pull cord, is connected at one end to a slide 45. The slide 45 is coupled to a disc 47 of the second carrier segment 16 via a long hole 46 and is biased by a spring 48; the slide is provided with a protrusion 49. When the actuating device is actuated or the pull cord 44 is pulled, the slide 45 moves along the long hole 46 / rail 50, the protrusion 49 presses the drive section 41 through a lateral opening, the latch 36 rotates, the engagement section 39 disengages from the receptacle, and the upper and lower support segments can be freely slid, the sleeping basket can be transferred into the stowed state.

[0388] When transferring from the stowed state into the use state, the upper support segment strut slides along the engagement section 39 (the spring 53 presses the latch 36 against the strut), the engagement section 39 first engages in the upper receptacle 38 ("emergency position") and finally in the lower receptacle 37; preferably by means of a ramp in a ratchet-like manner and self-locking in both positions, which can only be unlocked by means of the actuating device.

[0389] Figure D11 shows a section in the stowed state.

[0390] Figure D12 shows a plan view of the sleeping basket in the use state: the foot end 33 is provided with an actuating device 55 for releasing the above-mentioned locking mechanism in order to transfer the sleeping basket into the stowed state. The bottom plate is provided with transverse grooves 56-58 for rotatably accommodating the linkage crosspieces and with passages 59, 60 for accommodating the pull cord 44; the passages can be partially covered by screw-fixed retainers and the linkage can be fixed.

[0391] Fig. D13-15 shows an alternative embodiment: the support device 12 is pivotable, the upper support section 23 is rotatable relative to the lower support section 22 (intermediate state in Fig. D14, stowed state in Fig. D15). In a further embodiment, the support device can also be at least partially foldable or fully foldable to achieve the state transitions.

[0392] The present disclosure will now be described in relation to various examples described below and various combinations of these examples.
