DETAILED DESCRIPTION

FIG. 1 schematically shows a perspective view of a child carrier 1000 according to some embodiments of the present disclosure. The child carrier 1000 includes a supporting frame 300, a mattress 400, and a hammock 200 according to some embodiments of the present disclosure. The hammock 200 includes a supporting mechanism 100 according to some embodiments of the present disclosure. In the following, the hammock 200 and the supporting mechanism 100 will be described together as well as the child carrier 1000.

Referring to FIG. 1, in some embodiments, the child carrier 1000 is described by taking a child play yard as an example. Fences not shown in the figure may be attached to the perimeter and the bottom of the supporting frame 300. The fences define a receiving space of the child carrier 1000. A child may play in the receiving space. In some alternative embodiments, the child carrier 1000 may be a crib, a playpen, or other forms of child carriers 1000. In some embodiments, the supporting frame 300 may include four armrest supports 61, four top corner pieces 62, four support legs 63, four footings 64, and a connecting assembly 65. The four support legs 63 are located at four corners of a virtual quadrilateral (more specifically, a rectangle). The four top corner pieces 62 are mounted on top ends of the four support legs 63 respectively, and the four footings 64 are mounted at bottom ends of the four support legs 63 respectively. The four armrest supports 61 are connected to the four top corner pieces 62, to form a rectangular shape. Each of the footings 64 may be connected to the connecting assembly 65. In some embodiments, each armrest support 61 may be formed by assembling a plurality of foldable tube bodies. The connecting assembly 65 is also foldable, thereby allowing the supporting frame 300 to be folded. In some embodiments, the supporting frame 300 may alternatively be designed to be non-foldable.

Still referring to FIG. 1, the supporting frame 300 may support the hammock 200. The hammock 200 may include a hammock bottom sheet 51 and hammock peripheral sheets 52 extending upwards from perimeter edges of the hammock bottom sheet 51. An upper surface of the hammock bottom sheet 51 may serve as a bottom surface of the hammock 200, and a mattress may be provided on the bottom surface. The hammock bottom sheet 51 may be in a shape of a quadrilateral (more specifically, a rectangle). The hammock bottom sheet 51 and the four hammock peripheral sheets 52 surrounding the hammock bottom sheet 51 define a hammock space. In some embodiments, the hammock bottom sheet 51 and the four hammock peripheral sheets 52 are connected together by, for example, sewing. In some embodiments, for example, the hammock bottom sheet 51 and two opposite hammock peripheral sheets 52 are formed from different parts of a same sheet, and the same sheet and the other two opposite hammock peripheral sheets 52 are connected together by, for example, sewing. In some embodiments, the four hammock peripheral sheets 52 are formed, for example, from different parts of a same sheet, and then the same sheet and the hammock bottom sheet 51 are connected together by, for example, sewing.

In some embodiments, each of the hammock peripheral sheets 52 may be detachably connected to the corresponding armrest support 61 through a linking member 53, so that the hammock 200 is supported inside the supporting frame 300. When the fences are attached to the supporting frame 300, the hammock 200 is located in the receiving space defined by the fences. In some embodiments, top edges of the hammock peripheral sheet 52 may be provided with a plurality of linking members 53. Each linking member 53 may be a connecting hook, and each connecting hook may be easily hooked on the corresponding armrest support 61 or removed from the corresponding armrest support 61. It may be understood that in some alternative embodiments, the linking member 53 may be implemented in other ways and is not limited to the examples herein. For example, the linking member 53 may include a zipper or buckle, and the hammock peripheral sheet 52 may be connected to the corresponding fence (not shown) through the zipper or buckle.

Still referring to FIG. 1, the supporting mechanism 100 is located above the hammock bottom sheet 51. When the mattress 400 is placed on the hammock bottom sheet 51, the supporting mechanism 100 is located between the mattress 400 and the hammock bottom sheet 51. The supporting mechanism 100 may improve flatness of the mattress 400 placed on the hammock bottom sheet 51 and improve use comfort of the child. In some alternative embodiments, the supporting mechanism 100 may include at least one supporting member 2 configured to support the mattress 400. The supporting member 2 may not be arranged on the upper surface of the hammock bottom sheet 51 (i.e., the bottom surface of the hammock 200), and instead, the supporting member 2 is supported on the hammock bottom sheet 51 through another component, thereby supporting the mattress 400 located above the hammock bottom sheet 51. For example, the hammock bottom sheet 51 includes two layers of fabric, and the supporting member 2 may be located between the two layers of fabric. In this case, the supporting member 2 may be located below the bottom surface of the hammock 200. In this way, when the mattress 400 is placed on the upper surface of the hammock bottom sheet 51, the supporting mechanism 100 can support the mattress 400 through one layer of fabric of the hammock bottom sheet 51, which can also improve the flatness of the mattress 400.

FIGS. 2 to 4 illustrate an exemplary implementation of the supporting mechanism 100. The supporting mechanism 100 includes at least one connecting member 1 and at least one supporting member 2. More specifically, the supporting mechanism 100 includes four connecting members 1 and two supporting members 2. The connecting members 1 are respectively connected to the hammock 200, and more specifically, connected to the hammock bottom sheet 51. The four connecting members 1 are arranged, for example, adjacent to four corners of the hammock bottom sheet 51. Each supporting member 2 is, for example, a tube member, and two ends of the supporting member 2 are connected to two connecting members 1 respectively. Each of the ends of the supporting member 2 is engaged with the corresponding connecting member 1. The two supporting members 2 are parallel to each other and are configured to support the mattress 400. The supporting member 2 is connected to the connecting member 1 by engagement, improving convenience and quickness of assembly of the supporting mechanism 100.

Referring to FIG. 3, in some embodiments, the connecting member 1 is, for example, an injection molded part that is integrally formed. The connecting member 1 includes a mounting plate 11 and a sleeve portion 12 protruding from the mounting plate 11. The mounting plate 11 may be connected to the hammock bottom sheet 51 of the hammock 200 by, for example, sewing or riveting. The sleeve portion 12 encloses an accommodation cavity 10. The accommodation cavity 10 includes an insertion opening 101 and a bottom wall 103 that are opposite to each other. A peripheral wall of the accommodation cavity 10 is provided with an elastic arm 111. The elastic arm 111 is arranged, for example, in an unlocking operation opening 107 (see FIGS. 7 and 8) that is provided on the mounting plate 11 and in communication with the accommodation cavity 10. In other words, the unlocking operation opening 107 may be arranged on the peripheral wall of the accommodation cavity 10. The elastic arm 111 is provided with a limiting structure 112. The limiting structure 112 is, for example, a bump protruding from a free end of the elastic arm 111 towards interior of the accommodation cavity 10.

Referring to FIG. 4, in some embodiments, the supporting member 2 is, for example, a tube member made of metal, and have sufficient structural strength. The supporting member 2 may include a tube body 2a and a tube body 2b. The tube body 2a and the tube body 2b are detachably connected to allow the supporting member 2 to be disassembled into several shorter tube bodies for storage. In some embodiments, the tube body 2a has, for example, a first abutting end 21a (see FIG. 5), the tube body 2b has, for example, a second abutting end 21b, and the second abutting end 21b is, for example, in a necking shape (see FIG. 6). The second abutting end 21b may be inserted into the first abutting end 21a by a predetermined length, so that the tube body 2a and the tube body 2b are detachably connected to form the supporting member 2. In some alternative embodiments, the supporting member 2 may include an integrally formed tube body, and cannot be disassembled. Moreover, in some alternative embodiments, the supporting member 2 may include more than two tube bodies, and these tube bodies are detachably connected in sequence to form the supporting member 2.

Referring to FIGS. 4 and 5 as well as FIGS. 7 and 8, two ends of the supporting member 2 may also be referred to as insertion ends 21. Each insertion end 21 is inserted into the accommodation cavity 10 through the insertion opening 101 of the corresponding connecting member 1. An outer peripheral wall of the insertion end 21 is provided with an engaging hole 201. The engaging hole 201 is configured to be engaged with the limiting structure 112 of the elastic arm 111 and to restrict the insertion end 21 from being separated from the accommodation cavity 10. It may be understood that when the supporting member 2 is a tube member, the engaging hole 201 may run through the outer peripheral wall and an inner peripheral wall of the insertion end 21, so that the engaging hole 201 is in communication with an inner cavity of the tube member.

Referring to FIG. 8, during the insertion of the insertion end 21 into the accommodation cavity 10, the limiting structure 112 first abuts against an outer peripheral wall of the tip portion of the insertion end 21, so that the elastic arm 111 is deformed and has a tendency to move away from the outer peripheral wall of the insertion end 21. When the engaging hole 201 faces the limiting structure 112, the elastic arm 111 is reset, the limiting structure 112 is engaged with the engaging hole 201, and the insertion end 21 is limited in the accommodation cavity 10. More specifically, in some embodiments, a tail end surface 1121 of the limiting structure 112 is perpendicular to an axial direction of the accommodation cavity 10 (the axial direction of the accommodation cavity 10 may also be referred to as a direction in which the tube member is inserted), so as to prevent withdrawal of the insertion end 21 from the accommodation cavity 10 after the limiting structure 112 is engaged with the engaging hole 201. The limiting structure 112 may further have an abutment surface 1122 closer to the insertion opening 101 with respect to the tail end surface 1121. After the insertion end 21 is inserted into the accommodation cavity 10 by a certain depth, the edge of the insertion end 21 contacts the abutment surface 1122 and gradually presses the elastic arm 111 through the abutment surface 1122 during continued insertion, so that the elastic arm 111 is elastically deformed away from the outer peripheral wall of the insertion end 21. After the limiting structure 112 is aligned with the engaging hole 201, the elastic arm 111 rebounds and resets and is engaged with the engaging hole 201. In order to reduce damage to the limiting structure 112 and reduce insertion resistance of the insertion end 21, the abutment surface 1122 is an arc-shaped surface or a flat surface obliquely extending towards the accommodation cavity 10 and away from the insertion opening 101.

Referring to FIGS. 2, 3, and 8, in this embodiment, the elastic arm 111 is located at a lower part of the connecting member 1. When the supporting mechanism 100 is required to be repaired or replaced, the connecting member 1 and the supporting member 2 are required to be detached from each other. In this case, a user may apply a downward force F to the elastic arm 111 from below the hammock bottom sheet 51 (for example, extend a finger or a tool into the unlocking operation opening 107 to push the elastic arm 111 downwards), so that the limiting structure 112 is disengaged from the engaging hole 201. That is, the insertion end 21 of the supporting member 2 can be removed from the accommodation cavity 10 of the connecting member 1. In order to better store the supporting member 2 and prevent loss of the supporting member 2, when the hammock 200 or the supporting frame 300 is folded together with the hammock 200, the tube body 2a and the tube body 2b may be separated from each other, and the tube body 2a and the tube body 2b remain connected to the corresponding connecting members 1. Therefore, generally, after the connecting member 1 and the supporting member 2 are assembled together, only under abnormal use conditions such as repair or replacement, the supporting member 2 is required to be removed from the connecting member 1. In a normal use condition (e.g., when the hammock 200 is folded), the connecting member 1 and the supporting member 2 may be not detached from each other, and respective tube bodies of the supporting member 2 are separated from each other without affecting an engagement relationship between the tube bodies and the corresponding connecting members 1, so that the tube bodies of the supporting member 2 can be folded with the hammock 200, which can effectively prevent loss of the supporting member 2. In addition, in other embodiments, the elastic arm 111 may be arranged at other portion of the connecting member 1, and is not limited to a lower part of the connecting member 1.

In some embodiments, the hammock bottom sheet 51 may be made of mesh fabric, so that a force F can be applied to the elastic arm 111 across the hammock bottom sheet 51. In some embodiments, the unlocking operation opening 107 may have a large size to allow a human hand to directly apply the force F to the elastic arm 111 via the unlocking operation opening 107 without prying the elastic arm 111 by means of a tool.

In some alternative embodiments, both the accommodation cavity 10 and the insertion end 21 may have circular cross sections. When the insertion end 21 is inserted into the accommodation cavity 10 and is in place, if the limiting structure 112 is not engaged with the engaging hole 201 due to circumferential misalignment between the limiting structure 112 and the engaging hole 201, the user can rotate the supporting member 2 so that the limiting structure 112 and the engaging hole 201 are aligned with each other in a circumferential direction, so that the limiting structure 112 is engaged with the engaging hole 201.

In some embodiments, through reasonable arrangement of cross-sectional shapes of the peripheral wall of the accommodation cavity 10 and the outer peripheral wall of the insertion end 21, the insertion end 21 is inserted into the accommodation cavity 10 and is not rotatable relative to the accommodation cavity 10. In this way, before the insertion end 21 is inserted into the accommodation cavity 10, the engaging hole 201 and the limiting structure 112 can be aligned with each other in the circumferential direction, and then the insertion end 21 is inserted into the accommodation cavity 10. Since the insertion end 21 is not rotatable relative to the accommodation cavity 10, when the insertion end 21 is inserted into place, the engaging hole 201 is just engaged with the limiting structure 112. In addition, since the insertion end 21 is inserted into the accommodation cavity 10 and is not rotatable relative to the accommodation cavity 10, when the support member 2 is subjected to a large torque when supporting the mattress 400, breakage of the elastic arm 111 due to a direct impact of the large torque can be prevented.

Referring to FIGS. 3 and 9, in some embodiments, the peripheral wall of the accommodation cavity 10 and the outer peripheral wall of the insertion end 21 are provided with anti-rotation surfaces that cooperate with each other. More specifically, the anti-rotation surface arranged on the peripheral wall of the accommodation cavity 10 may be referred to as a first anti-rotation surface 105 (see FIG. 3), and the anti-rotation surface arranged on the outer peripheral wall of the insertion end 21 may be referred to as a second anti-rotation surface 203 (see FIG. 9). When the insertion end 21 is inserted into the accommodation cavity 10, the first anti-rotation surface 105 is in contact with the second anti-rotation surface 203, preventing relative rotation between the insertion end 21 and the accommodation cavity 10.

In some embodiments, one or more (no less than two) first anti-rotation surfaces 105 may be provided, and one or more (no less than two) second anti-rotation surfaces 203 may also be provided. When one first anti-rotation surface 105 and one second anti-rotation surface 203 are provided, the cooperation between the first anti-rotation surface 105 and the second anti-rotation surface 203 can achieve a fool-proofing effect and guide the user to insert the insertion end 21 into the accommodation cavity 10 in such a manner that the engaging hole 201 and the limiting structure 112 are aligned with each other in the circumferential direction. When a plurality of first anti-rotation surfaces 105 and a plurality of second anti-rotation surfaces 203 are provided and the plurality of first anti-rotation surfaces 105 and the plurality of second anti-rotation surfaces 203 are arranged at non-uniform intervals in the circumferential direction, the cooperation between the plurality of first anti-rotation surfaces 105 and the plurality of second anti-rotation surfaces 203 may also achieve a fool-proofing effect.

Referring to FIG. 3, the peripheral wall of the accommodation cavity 10 may include a first arc-shaped wall 104 and the first anti-rotation surface 105 located at an opening of the first arc-shaped wall 104. Referring to FIGS. 5 and 9, the outer peripheral wall of the insertion end 21 may include a second arc-shaped wall 202 and the second anti-rotation surface 203 located at an opening of the second arc-shaped wall 202. The shape of the peripheral wall of the accommodation cavity 10 and the shape of the outer peripheral wall of the insertion end 21 are designed as above so that a fool-proofing effect can be achieved, which ensures that during the insertion of the insertion end 21, the engaging hole 201 and the limiting structure 112 remain aligned with each other in the circumferential direction, thereby guiding the insertion end 21 to be correctly inserted into the accommodation cavity 10. In some embodiments, the first anti-rotation surface 105 is away from the mounting plate 11, and the elastic arm 111 is arranged on the first arc-shaped wall 104 and faces the first anti-rotation surface 105. Correspondingly, the engaging hole 201 is arranged on the second arc-shaped wall 202 and faces the second anti-rotation surface 203.

Referring to FIGS. 3 and 4, in some embodiments, a guide structure 3 may be further arranged between the peripheral wall of the accommodation cavity 10 and the outer peripheral wall of the insertion end 21. The guide structure 3 is configured to guide the insertion end 21 to be inserted into the accommodation cavity 10 and further prevent rotation of the insertion end 21 relative to the accommodation cavity 10. The guide structure 3 includes, for example, a guide rib 31 and a guide groove 32. The guide rib 31 is arranged, for example, on the peripheral wall of the accommodation cavity 10. The guide groove 32 is arranged, for example, on the outer peripheral wall of the insertion end 21. The guide rib 31 and the guide groove 32 are in sliding fit. In some alternative embodiments, the guide rib 31 may be arranged, for example, on the outer peripheral wall of the insertion end 21, and the guide groove 32 may be arranged, for example, on the peripheral wall of the accommodation cavity 10.

It may be understood that through the reasonable arrangement of the positions of the guide rib 31 and the guide groove 32, the cooperation between the guide rib 31 and the guide groove 32 may also achieve a fool-proofing effect, and guide the insertion end 21 to be correctly inserted into the accommodation cavity 10.

Still referring to FIGS. 3 and 4, in order to facilitate processing of the guide rib 31 and the guide groove 32, in some embodiments, the guide rib 31 is arranged, for example, on the first anti-rotation surface 105, and the guide groove 32 is arranged, for example, on the second anti-rotation surface 203. In some embodiments, the second anti-rotation surface 203 and the guide groove 32 are made for example, by stamping the insertion end 21. In some embodiments, a partial region of the second anti-rotation surface 203 is stamped, so that the partial region of the second anti-rotation surface 203 is recessed towards interior of the supporting member 2, and the guide groove 32 can be formed.

Referring to FIG. 3 and FIGS. 7 to 9, in some embodiments, a bottom wall 103 of the accommodation cavity 10 is provided with at least one positioning rib 41. The positioning rib 41 protrudes towards the insertion opening 101 and extends in a direction D (see FIG. 8). The direction D is, for example, perpendicular to the direction in which the supporting member 2 is inserted. The insertion end 21 is provided with at least one positioning notch 42. When the insertion end 21 is inserted into the accommodation cavity 10 and is in place, the engaging hole 201 is engaged with the limiting structure 112, and the positioning rib 41 is engaged with the positioning notch 42. The cooperation between the positioning rib 41 and the positioning notch 42 can further prevent the relative rotation of the insertion end 21 and the accommodation cavity 10.
