[0041] Figure 1 A perspective view of a child carrier 1000 provided according to some embodiments of the present invention is schematically shown, and the child carrier 1000 includes a support frame 300, a mattress 400, and a hammock 200 provided according to some embodiments of the present invention. The hammock 200 includes a support mechanism 100 provided according to some embodiments of the present invention. The hammock 200 and the support mechanism 100 will be described together with the child carrier 1000 hereinafter.

[0042] See also Figure 1 In some embodiments, the child carrier 1000 is described by taking a children's playbed as an example. The surroundings and bottom of the support frame 300 may be attached with fences not shown in the figure. The fences define the accommodation space of the child carrier 1000, and the children can play in the accommodation space. In some alternative embodiments, the child carrier 1000 may be a child carrier 1000 in other forms such as a crib and a playpen. In some embodiments, the support frame 300 may include four armrests 61, four top corner pieces 62, four support legs 63, four bottom feet 64 and a connecting assembly 65. The four support legs 63 are located at the four corners of a virtual quadrilateral (more specifically, a rectangle). The four top corner pieces 62 are respectively mounted on the tops of the four support legs 63, and the four bottom feet 64 are respectively mounted on the bottoms of the four support legs 63. The four armrests 61 are connected to the four top corner pieces 62 and enclosed in a rectangular shape. Each bottom foot 64 can be connected to the connecting assembly 65. In some embodiments, each handrail frame 61 can be composed of a plurality of foldable tubes, and the connecting assembly 65 can also be foldable, thereby allowing the support frame 300 to be foldable. Of course, in some embodiments, the support frame 300 can also be designed to be non-foldable.

[0043] Continue to see Figure 1, the support frame 300 can support the hammock 200. The hammock 200 may include a hammock bottom sheet 51 and a hammock surrounding sheet 52 extending upward from the edges of the hammock bottom sheet 51. The upper surface of the hammock bottom sheet 51 can be used as the bottom surface of the hammock 200 and a mattress can be laid, and the shape of the hammock bottom sheet 51 is a quadrilateral (more specifically, a rectangular shape). The hammock bottom sheet 51 and the four hammock surrounding sheets 52 around it define a hammock space. In some embodiments, the hammock bottom sheet 51 is combined with the four hammock surrounding sheets 52 around it, for example, by sewing. In some embodiments, the hammock bottom sheet 51 is formed by different parts of the same sheet with two opposite hammock surrounding sheets 52, and the same sheet and the other two opposite hammock surrounding sheets 52 are combined together, for example, by sewing. In some embodiments, the four hammock surrounding sheets 52 around it are formed by different parts of the same sheet, and then the same sheet and the hammock bottom sheet 51 are combined together, for example, by sewing.

[0044] In some embodiments, the hammock sheet 52 can be detachably connected to the handrail 61 through a joint 53 so that the hammock 200 is supported inside the support frame 300. When the support frame 300 is attached with a fence, the hammock 200 is located in the accommodation space defined by the fence. In some embodiments, a plurality of joints 53 can be provided on the top edge of the hammock sheet 52, and each joint 53 can be a connecting hook, and each connecting hook can be easily hooked on or removed from the corresponding handrail 61. It is understood that in some alternative embodiments, the joint 53 can have other embodiments and is not limited to the examples in this article. For example, the joint 53 can include a zipper or a buckle, and the hammock sheet 52 can be connected to a fence not shown by the zipper or the buckle.

[0045] Continue to see Figure 1 , the support mechanism 100 is located above the hammock base sheet 51, and when the mattress 400 is placed on the hammock base sheet 51, the support mechanism 100 is located between the mattress 400 and the hammock base sheet 51. The support mechanism 100 can improve the flatness of the mattress 400 placed on the hammock base sheet 51, and improve the comfort of use for infants and young children. In some alternative embodiments, the support member 2 may not be arranged on the upper surface of the hammock base sheet 51 (i.e., the bottom surface of the hammock 200), but the support member 2 may be supported on the hammock base sheet 51 by other structures, thereby supporting the mattress 400 located above the hammock base sheet 51. For example, the hammock base sheet 51 includes a double layer of fabric, and the support member 2 may be located between the double layers of fabric. In this case, the support 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 base sheet 51, the support mechanism 100 can support the mattress 400 through a layer of fabric of the hammock base sheet 51, and the flatness of the mattress 400 can also be improved.

[0046] Figures 2 to 4An exemplary embodiment of a support mechanism 100 is shown. The support mechanism 100 includes at least one connecting member 1 and at least one supporting member 2. More specifically, the support mechanism 100 includes four connecting members 1 and two supporting members 2. Each connecting member 1 is connected to the hammock 200, more specifically, to the hammock bottom sheet 51. The four connecting members 1 are, for example, disposed adjacent to the four corners of the hammock bottom sheet 51. Each supporting member 2 is, for example, a pipe fitting, and two ends of the support member 2 correspond to two connecting members 1. Each end of the support member 2 is respectively snap-connected with the corresponding connecting member 1, and the two supporting members 2 are parallel to each other and are used to support the mattress 400. The support member 2 is connected to the connecting member 1 by snap-connection, which improves the convenience and quickness of assembly of the support mechanism 100.

[0047] See also Figure 3 In some embodiments, the connector 1 is, for example, an integrally formed injection molded part, and the connector 1 includes a mounting plate 11 and a sleeve portion 12 protruding from the mounting plate 11. The mounting plate 11 can be connected to the hammock bottom plate 51 of the hammock 200 by, for example, sewing, riveting, etc. The sleeve portion 12 forms a receiving cavity 10, and the receiving cavity 10 includes an insertion port 101 and a bottom wall 103 that are opposite to each other. The peripheral wall of the receiving cavity 10 is provided with an elastic arm 111. The elastic arm 111 is, for example, provided at a release operation port 107 (see FIG. 1 ) opened on the mounting plate 11 and communicating with the receiving cavity 10. Figure 7 and Figure 8 ), the unlocking operation port 107 can also be said to be arranged on the peripheral wall of the accommodating cavity 10. The elastic arm 111 is provided with a limiting structure 112, which is, for example, a convex block protruding from the free end of the elastic arm 111 toward the inside of the accommodating cavity 10.

[0048] See also Figure 4 In some embodiments, the support member 2 is, for example, a metal pipe to have sufficient structural strength. The support member 2 may include a pipe body 2a and a pipe body 2b, and the pipe body 2a and the pipe body 2b are detachably connected to allow the support member 2 to be disassembled into a plurality of shorter pipe bodies for storage. In some embodiments, the pipe body 2a, for example, has a first butt end 21a (see Figure 5 ), the tube body 2b has, for example, a second butt end 21b, which is, for example, a constricted shape (see Figure 6 ). The second butt end 21b can be inserted into the first butt end 21a by a predetermined length, so that the tube body 2a and the tube body 2b are detachably connected to form the support member 2. Of course, in some alternative embodiments, the support member 2 may include a whole tube body and is not detachable. Also, in some alternative embodiments, the support member 2 may include more than two tube bodies, which are detachably connected in sequence to form the support member 2.

[0049] See also Figure 4 and Figure 5 as well as Figure 7 and Figure 8 The two ends of the support member 2 can also be called plug-in ends 21, and each plug-in end 21 is inserted into the accommodating cavity 10 through the corresponding plug-in interface 101 of the connector 1. A bayonet 201 is provided on the outer peripheral wall of the plug-in end 21, and the bayonet 201 is used to engage with the limiting structure 112 of the elastic arm 111 and limit the plug-in end 21 from being pulled out of the accommodating cavity 10. It can be understood that when the support member 2 adopts a pipe fitting, the bayonet 201 can pass through the outer peripheral wall and the inner peripheral wall of the plug-in end 21, so that the bayonet 201 is connected with the inner cavity of the pipe fitting.

[0050] See also Figure 8 In the process of inserting the plug end 21 into the accommodating cavity 10, the limiting structure 112 first abuts against the peripheral wall of the edge of the plug end 21, so that the elastic arm 111 is deformed and has a tendency to move away from the peripheral wall of the plug end 21. When the bayonet 201 is opposite to the limiting structure 112, the elastic arm 111 is reset, the limiting structure 112 is engaged with the bayonet 201, and the plug end 21 is restricted in the accommodating cavity 10. More specifically, in some embodiments, the end face 1121 of the limiting structure 112 is perpendicular to the axial direction of the accommodating cavity 10 (the axial direction of the accommodating cavity 10 can also be called the plug-in direction of the pipe fitting), so that the limiting structure 112 prevents the plug end 21 from withdrawing from the accommodating cavity 10 after the bayonet 201 is engaged. The limiting structure 112 can also have an abutting surface 1122 close to the plug port 101 relative to the end face 1121. After the plug end 21 is inserted into the accommodating cavity 10 to a certain depth, the edge of the plug end 21 contacts the abutment surface 1122 and gradually presses the elastic arm 111 through the abutment surface 1122 during the continued insertion, so that the elastic arm 111 is elastically deformed and moves away from the outer peripheral wall of the plug end 21. When the limiting structure 112 and the bayonet 201 are aligned, the elastic arm 111 rebounds and resets and engages with the bayonet 201. In order to reduce damage to the limiting structure 112 and reduce the plugging resistance of the plug end 21, the abutment surface 1122 is an arc surface or a plane that extends obliquely toward the accommodating cavity 20 and away from the plug interface 101.

[0051] See also Figure 2 , Figure 3 and Figure 8In this embodiment, the elastic arm 111 is located at the lower part of the connecting member 1. When the supporting mechanism 100 needs to be repaired or replaced, the connecting member 1 and the supporting member 2 need to be disassembled. At this time, the user can apply a downward force F to the elastic arm 111 from the bottom of the hammock bottom plate 51 (for example, by entering the unlocking operation port 107 with a finger or a tool and pushing the elastic arm 111 downward), so that the limiting structure 112 is disengaged from the bayonet 201, that is, the plug-in end 21 of the supporting member 2 can be removed from the accommodating cavity 10 of the connecting member 1. Of course, in order to better store the supporting member 2 and avoid the support member 2 from being lost, when the folding hammock 200 or the supporting frame 300 is folded together with the hammock 200, the tube body 2a and the tube body 2b can be separated from each other, and the connection between the tube body 2a, the tube body 2b and the corresponding connecting member 1 is maintained. Therefore, generally speaking, after the connector 1 and the support member 2 are assembled, the support member 2 is usually required to be disassembled from the connector 1 only in abnormal use conditions such as maintenance or replacement. In normal use conditions (such as folding the hammock 200), the connector 1 and the support member 2 do not need to be disassembled, but the various tubes of the support member 2 are separated without affecting the clamping relationship between each tube and the corresponding connector 1, so that the various tubes of the support member 2 can be folded together with the hammock 200, which can effectively avoid the loss of the support member 2. In addition, in other embodiments, the elastic arm 111 can be set at other positions of the connector 1, and is not limited to the lower part of the connector 1.

[0052] In some embodiments, the hammock bottom sheet 51 may be made of a mesh fabric, which facilitates applying force F to the elastic arm 111 through the hammock bottom sheet 51. In some embodiments, the unlocking operation opening 107 may have a larger size to allow a person's hand to directly apply force F to the elastic arm 111 at the unlocking operation opening 107 without the need to pry the elastic arm 111 with the aid of a tool.

[0053] In some alternative embodiments, the accommodating cavity 10 and the plug end 21 may both have circular cross-sections. When the plug end 21 is inserted into the accommodating cavity 10, if the limiting structure 112 is not engaged with the bayonet 201 due to the circumferential misalignment between the limiting structure 112 and the bayonet 201, the user may rotate the support member 2 so that the limiting structure 112 is aligned with the bayonet 201 in the circumferential direction, and the limiting structure 112 is engaged with the bayonet 201.

[0054] In some embodiments, by reasonably setting the cross-sectional shapes of the peripheral wall of the accommodating cavity 10 and the outer peripheral wall of the connecting end 21, the plug-in end 21 can be inserted into the accommodating cavity 10 without being relatively rotatable. In this way, before inserting the plug-in end 21 into the accommodating cavity 10, align the circumferential positions of the bayonet 201 and the limiting structure 112, and then insert the plug-in end 21 into the accommodating cavity 10. Because the plug-in end 21 cannot rotate relative to the accommodating cavity 10, when the plug-in end 21 is inserted into place, the bayonet 201 is just engaged with the limiting structure 112. In addition, since the plug-in end 21 is inserted into the accommodating cavity 10 without being relatively rotatable, it can be avoided that when the support member 2 is subjected to a large torque when supporting the mattress 400, the elastic arm 111 is directly subjected to a large torque impact and broken.

[0055] See also Figure 3 and Fig. 9 In some embodiments, the peripheral wall of the accommodating cavity 10 and the outer peripheral wall of the plug end 21 are provided with anti-rotation surfaces that cooperate with each other. More specifically, the anti-rotation surface provided on the peripheral wall of the accommodating cavity 10 can be referred to as a first anti-rotation surface 105 (see Figure 3 ), the anti-rotation surface provided on the outer wall of the plug end 21 is a second anti-rotation surface 203 (see Fig. 9 When the plug-in end 21 is inserted into the accommodating cavity 10, the first anti-rotation surface 105 and the second anti-rotation surface 203 are in contact with each other, so as to prevent the plug-in end 21 and the accommodating cavity 10 from rotating relative to each other.

[0056] In some embodiments, the number of the first anti-rotation surface 105 can be one or more (not less than two), and the number of the second anti-rotation surface 203 can also be one or more (not less than two). When the number of the first anti-rotation surface 105 and the second anti-rotation surface 203 are both one, the cooperation of the first anti-rotation surface 105 and the second anti-rotation surface 203 can play a fool-proof role, guiding the user to insert the plug end 21 into the accommodating cavity 10 in a manner that the bayonet 201 and the limiting structure 112 are aligned in the circumferential direction. When there are multiple first anti-rotation surfaces 105 and second anti-rotation surfaces 203, and the multiple first anti-rotation surfaces 105 and the multiple second anti-rotation surfaces 203 are arranged in a non-uniformly spaced manner in the circumferential direction, the cooperation of the multiple first anti-rotation surfaces 105 and the multiple second anti-rotation surfaces 203 can also play a fool-proof role.

[0057] See also Figure 3 The peripheral wall of the accommodating cavity 10 may include a first arc-shaped wall 104 and a first anti-rotation surface 105 located at the opening of the first arc-shaped wall 104. Figure 5 and Fig. 9, the outer peripheral wall of the plug end 21 may include a second arcuate wall 202 and a second anti-rotation surface 203 located at the opening of the second arcuate wall 202. This design of the peripheral wall shape of the accommodating cavity 10 and the peripheral wall shape of the plug end 21 plays a foolproof role, ensuring that during the insertion process of the plug end 21, the bayonet 201 and the limiting structure 112 remain aligned in the circumferential direction, thereby guiding the plug end 21 to be correctly inserted into the accommodating 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 arcuate wall 104 and opposite to the first anti-rotation surface 105. Correspondingly, the bayonet 201 is arranged on the second arcuate wall 202 and opposite to the second anti-rotation surface 203.

[0058] See also Figure 3 and Figure 4 In some embodiments, a guide structure 3 may be provided between the peripheral wall of the accommodating cavity 10 and the outer peripheral wall of the plug end 21, and the guide structure 3 is used to guide the plug end 21 to be inserted into the accommodating cavity 10, and further prevent the plug end 21 from rotating relative to the accommodating cavity 10. The guide structure 3, for example, includes a guide rib 31 and a guide groove 32, wherein the guide rib 31 is, for example, provided on the peripheral wall of the accommodating cavity 10, and the guide groove 32 is, for example, provided on the outer peripheral wall of the plug end 21, and the guide rib 31 and the guide groove 32 are slidably matched. Of course, in some alternative embodiments, the guide rib 31 may be, for example, provided on the outer peripheral wall of the plug end 21, and the guide groove 32 may be provided on the peripheral wall of the accommodating cavity 10.

[0059] It can be understood that by reasonably setting the positions of the guide rib 31 and the guide groove 32 , the cooperation between the guide rib 31 and the guide groove 32 can also play an anti-mistake effect, guiding the plug-in end 21 to be correctly inserted into the accommodating cavity 10 .

[0060] Continue to see Figure 3 and Figure 4 In order to facilitate the processing of the guide rib 31 and the guide groove 32, in some embodiments, the guide rib 31 is, for example, disposed on the first anti-rotation surface 105, and the guide groove 32 is, for example, disposed on the second anti-rotation surface 203. In some embodiments, the second anti-rotation surface 203 and the guide groove 32 are, for example, made by stamping the plug-in end 21. In some embodiments, a partial area of ​​the second anti-rotation surface 203 is stamped so that the partial area of ​​the second anti-rotation surface 203 is recessed toward the inside of the support member 2, thereby forming the guide groove 32.

[0061] See also Figure 3 , Figures 7 to 9 In some embodiments, the bottom wall 103 of the accommodating cavity 10 is provided with at least one positioning rib 41, which protrudes toward the plug-in port 101 and extends in the direction D (see Figure 8), the direction D is, for example, perpendicular to the plug-in direction of the support member 2. The plug-in end 21 is provided with at least one positioning notch 42. When the plug-in end 21 is plugged into place in the accommodating cavity 10, the bayonet 201 and the limiting structure 112 are engaged, 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 plug-in end 21 and the accommodating cavity 10 from rotating relative to each other. It can be understood that in this embodiment, the first anti-rotation surface 105 extends from the edge of the plug-in port 101 toward the bottom wall 103, and the first anti-rotation surface 105 can prevent the plug-in end 21 and the accommodating cavity 10 from rotating relative to each other when the plug-in end 21 begins to be inserted into the accommodating cavity 10 and during the plug-in process, and the cooperation between the positioning rib 41 and the positioning notch 42 is to prevent the plug-in end 21 and the accommodating cavity 10 from rotating relative to each other when the plug-in end 21 is about to be plugged into place or after being plugged into place. The cooperation between the positioning rib 41 and the positioning notch 42 further facilitates the insertion and positioning of the plug-in end 21 and the accommodating cavity 10 in the axial direction and the circumferential direction.

[0062] In some embodiments, see Fig. 9 , the plug end 21 may be provided with two positioning notches 42, the two positioning notches 42 are opposite to each other and are engaged with the two ends of the same positioning rib 41. In some embodiments, one of the two positioning notches 42 may be provided at the edge of the second anti-rotation surface 203. In some alternative embodiments, the number of positioning notches 42 is not limited to two, and the number of positioning ribs 41 is not limited to one, and the number of positioning notches 42 and the number of positioning ribs 41 may be consistent, so that the positioning notches 42 and the positioning ribs 41 are engaged in a one-to-one correspondence.

[0063] In some embodiments not shown, the carrier 1000 provided in the above embodiment of the present invention may also be modified as follows.

[0064] 1. One or more (not less than two) support members 2 may be provided, and two ends of each support member 2 correspond to two connecting members 1. When there are multiple support frames 2, multiple support members 2 may be provided in parallel with each other. Alternatively, multiple support members 2 may be provided in groups of two and crosswise. Alternatively, some of the multiple support members 2 may be provided in parallel with each other, and the other parts may be provided in a crosswise manner.

[0065] Second, although the above embodiments are described by taking the example that the accommodating cavity 10 is provided on the connector 1 and the plug end 21 is provided on the support 2, in some alternative embodiments, the positions of the accommodating cavity 10 and the plug end 21 on the connector 1 and the support 2 can be interchanged. That is, the accommodating cavity can be provided on the support 2 (for example, when the support 2 is a pipe, the inner cavity of the pipe can be directly used as the accommodating cavity), and the connector 1 is correspondingly provided with the plug end 21 for inserting into the inner cavity of the pipe.

[0066] 3. Although the above embodiment is described by taking the elastic arm 111 being arranged on the wall of the accommodating cavity 10 and the bayonet 201 being arranged on the wall of the plug end 21 as an example, in some alternative embodiments, the positions of the elastic arm 111 and the bayonet 201 on the accommodating cavity 10 and the plug end 21 can be interchanged. That is, the elastic arm 111 can be arranged on the wall of the plug end 21, the limiting structure protrudes outward from the free end of the elastic arm 111 relative to the outer peripheral wall of the plug end 21, and the bayonet 201 can be arranged on the peripheral wall of the accommodating cavity 10.

[0067] 4. Although in the above embodiment, both ends of each support member 2 are connected to two connecting members 1, in some alternative embodiments, one end of each support member 2 may be connected to one connecting member 1, and the other end may be pivotally connected to a pivot seat (not shown) located in the middle of the hammock bottom plate 51. A plurality of support members 2 connected to the pivot seat are radially arranged.

[0068] Fig.10 A three-dimensional view of a hammock 200 provided according to some embodiments of the present invention is shown, and the hammock 200 is equipped with a support mechanism 100. Similar to the above-mentioned embodiments, the hammock 200 includes a hammock bottom sheet 51 and a hammock surrounding sheet 52 extending upward from the edges of the hammock bottom sheet 51. A plurality of joints 53 may be provided on the top edge of the hammock surrounding sheet 52, and the plurality of joints 53 are used to connect with the support frame 300. The support mechanism 100 equipped with the hammock 200 is different from the support mechanism 100 in the above-mentioned embodiments.

[0069] See also Figures 10 to 12 The support mechanism 100 includes a plurality of connectors 1 and a plurality of support members 2. The plurality of connectors 1 are disposed, for example, adjacent to the four corners of the hammock bottom sheet 51. Each connector 1 includes, for example, a connecting strap 13, which may be, for example, a webbing. The first end 131 of the connecting strap 13 is connected to the hammock bottom sheet 51 or the hammock surrounding sheet 52 of the hammock 200, and the second end 132 of the connecting strap 13 may be provided with a limiting structure 133. In some embodiments, the limiting structure 133 may be a bow formed by the connecting strap itself (see Fig.11 ), for example, the ribbon is sewed to form a bow. In some embodiments, the limiting structure 133 can be a Japanese buckle connected to the connecting belt 13 (see Fig.12 ), and of course, it can also be replaced by parts such as eyelet buckles. Each support member 2 can be a pipe, and the hollow inner cavity of the pipe forms a receiving cavity 20. The two ends of the pipe are respectively provided with a bayonet 201, and the bayonet 201 communicates with the receiving cavity 20.

[0070] When the support member 2 needs to be connected to the connecting member 1, the second end 132 of the connecting belt 13 and the limiting structure 133 can be inserted into the accommodating cavity 20 through the bayonet 201, and then the limiting structure 133 can be engaged with the edge of the bayonet 201 and cannot be withdrawn from the bayonet 201, so that the support member 2 and the connecting member 1 can be conveniently connected together. Fig.11 The limiting structure 133 is in the shape of a bow. The limiting structure 133 is gradually squeezed by the clip 201 during the insertion into the accommodating cavity 20. When the bow completely enters the accommodating cavity 20, the bow naturally unfolds and clips with the edge of the clip 201. Fig.12 The limiting structure 133 in the form of a Japanese buckle is first adjusted to be roughly in contact with the plane of the connecting belt 13 before being inserted into the accommodating cavity 20, so that the second end 132 of the connecting belt 13 and the limiting structure 133 are relatively flat as a whole, and then the limiting structure 133 is gradually inserted into the accommodating cavity 20 through the bayonet 201. When the limiting structure 133 completely enters the accommodating cavity 20, the limiting structure 133 rotates relative to the connecting belt 13, and the limiting structure 133 is roughly perpendicular to the second end 132 of the connecting belt 13 and is engaged with the edge of the bayonet 201. In some embodiments, the support member 2 can be formed by at least two shorter tubes connected in sequence in a detachable manner, so that the support member 2 can be disassembled into multiple shorter tubes and then stored.

[0071] It is understood that the location of the bayonet 201 is not limited to the two ends of the support member 2. For example, in some embodiments, one or more bayonet 201 may be provided between the two ends of the support member 2. One or more connecting straps 13 are correspondingly provided along the length direction of the support member 2.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
