DETAILED DESCRIPTION OF THE INVENTION

[0028]

[0023] Exemplary embodiments will now be described in detail with reference to the drawings. While the present disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings. However, the present disclosure should not be construed as being limited to the embodiments disclosed herein; rather, the present disclosure will cover all modifications, equivalents, and alternatives falling within the spirit and scope of the embodiments.

[0029] Although the invention is illustrated and described herein with reference to specific embodiments, the invention should not be limited to the details shown. Indeed, various changes can be made in these details within the scope of the equivalent scheme of the claims and without departing from the invention.

[0030] Directional descriptions such as "front," "back," "left," "right," "up," and "down" in this specification are for the convenience of understanding, and the present invention is not limited to these directions and can be adjusted according to actual circumstances. Although the present application has been described with reference to exemplary embodiments, the terms used are for explanation and illustration, and are not limiting terms.

[0031] 1 to 4 show a child carrier according to one embodiment and perspective views of a carrier body A10 and a part A20 of the child carrier, respectively.

[0032] FIG. 1 shows a perspective view of a child carrier according to one embodiment. The child carrier may be, for example, a baby bed A1, which provides a sleeping and playing space for a baby. The child carrier mainly comprises a carrier body A10. To facilitate removal and storage, the carrier body A10 is assembled using multiple levers and interconnected by multiple joints A130. These levers include, for example, multiple first levers A100 surrounding a rectangular ring that forms the upper part of the carrier body A10 as an upper frame on which the child is supported. Four legs A110 are inserted into the joints A130 at the four corners of the upper frame formed by the first levers A100 to support the child carrier on the ground. To ensure that the four legs A110 stand more stably, support members A120 made of levers are provided between the four legs A110 to form the bottom frame of the baby bed A1. According to this embodiment, one end of each of the support members A120 is inserted into the joint A130, and the other end is fixed to the lower end of the leg A110 by, for example, a bolt. According to the present application, the outside of the baby bed A1 can be covered with a seat cushion or the like to form a space for babies to play or rest, and can also serve, for example, as an aesthetic feature.

[0033] According to the present application, the joint A130 may have various shapes so that the lever can be assembled into a removable child carrier. The present application does not limit the specific shape of the joint A130 to the drawings.

[0034] As shown in FIG. 1, multiple components A20, such as a diaper changing table, a sleeping basket, and a spring chair, are detachably connected to the crib A1 to enhance the versatility of use of the crib A1 when the crib A1 is not being used for baby sleep. The left side of FIG. 1 shows a spring chair surrounded by multiple second levers A200, which form a support and have cantilevers extending downward from the support. The cantilevers of the spring chair can be placed on the ground or a platform for the child to dance on. The right side of FIG. 1 shows a schematic diagram of a diaper changing table surrounded by multiple second levers A200, which form a support for supporting and securing the child's body, such as a board or cushion, placed on the diaper changing table. The second levers A200 forming the spring chair and the second levers A200 forming the diaper changing table may have the same shape for ease of manufacturing.

[0035] According to the present disclosure, the spring chair and the diaper table are mounted in parallel on the carrier body A10, with the diaper table having a length L1 and a width W1, and the spring chair having a length L2 and a width W2. Because the length L1 is substantially equal to the length L2 and the lever configurations are substantially the same, the spring chair and the diaper table can be detachably secured to, e.g., engaged with, the first lever A100 of the carrier body A10 using the same connecting device A30. According to this embodiment, one connecting device A30 is provided on each side of the spring chair and the diaper table along the lengths L1 and L2. The internal configuration of the connecting device A30 will be described in detail in FIGS. 8 to 10 based on the cross-sectional lines II, II-II, III-III, and IV-IV of portion A in FIG. 1.

[0036] Optionally, the width W1 of the diaper table can be equal to the width W2 of the spring chair so that each part A20 has approximately the same outline dimensions.

[0037] FIG. 2 shows a perspective view of the carrier body A10 of a child carrier according to one embodiment. The diaper changing table and spring chair have been removed in FIG. 2, allowing a better view of the carrier body A10's configuration. The upper frame may comprise, for example, eight first levers A100, with a joint A130 provided between two of the first levers A100. The joints A130 and the first levers A100 may be connected by insert, hinge, pivot, or other means, thereby forming a rectangular upper frame. The legs A110 may be rotatably connected to the support member A120 via bolt connections, allowing the legs A110 and support member A120 to be folded together when not in use.

[0038] According to this embodiment, the first lever A100 is provided with an engagement portion A101 at a position for connecting the part A20 in FIG. 1, i.e., at the position of the connecting device A30, for positioning and engaging the connecting device A30 of the part A20. According to this embodiment, the engagement portion A101 is provided on the first lever A100 facing outward and provides for positioning of the connecting device A30 between the spring chair and the diaper changing table. Of course, the engagement portion A101 may also be provided on the first lever A100 facing inward, and the present invention is not limited thereto. According to this embodiment, the engagement portion A101 is, for example, two engagement recesses to provide more stable positioning and engagement. Of course, the shape and number of the engagement portions A101 are not limited thereto. For example, the engagement portion A101 may be in the form of an engagement protrusion, and the number of engagement portions A101 may be three, four, or more. The first lever A100 on the other side of the carrier body A10 has engagement portions A101 symmetrically provided thereon. The engaging portion A101 can engage with an engaging structure (described below) provided corresponding to the connecting device A30, thereby positioning and engaging the connecting device A30 with the first lever A100. This allows the connecting device A30 to be engaged with the carrier body A10 only when the corresponding engaging structure is aligned with the engaging portion A101 when attaching the part A20 to the carrier body A10, thereby providing a stable and clear attachment portion for the part A20.

[0039] FIG. 3 shows a top perspective view of part A20 according to one embodiment, taking a diaper changing table as an example. The main body of part A20 is a support part, which includes a plurality of second levers A200 and may be bent by a single second lever A200. The support part forms a rectangular frame structure. Opposite sides of part A20 are provided with connecting devices A30 for attaching to and engaging with the first levers A100 (see FIGS. 1 and 2) of carrier body A10. According to this embodiment, the connecting devices A30 are disposed on the second levers A200; for example, the second levers A200 are connected through the connecting devices A30 and optionally fixedly connected to the connecting devices A30.

[0040] According to this embodiment, the connection device A30 includes a fixed base A310 and a cover A300 that fits over the fixed base A310. The second lever A200 passes through and connects to the connection device A30. The fixed base A310 and the cover A300 can be engaged with each other, glued, bolted, or the like. As can be seen from FIG. 3 , the fixed base A310 and the cover A300 form a receiving portion corresponding to the cross-sectional shape of the second lever A200 to better hold and secure the second lever A200. That is, the fixed base A310 and the cover A300 can each have a semicircular structure. In another embodiment, the fixed base A310 and the cover A300 can be integrally molded.

[0041] According to this embodiment, the fixed base A310 has an engagement groove A320 on the side away from the second lever A200, which opens vertically and extends in the direction of extension of the second lever A200. This allows the first lever A100 of the carrier body A10 to fit into the engagement groove A320 when the connecting device A30 engages with the carrier body A10. In other words, a portion of the first lever A100 can be accommodated in the engagement groove A320. When the part A20 and the carrier body A10 are assembled, the first lever A100 and the second lever A200 are parallel to each other (see FIG. 1). Of course, the first lever A100 and the second lever A200 do not have to be parallel to each other. For example, the second lever A200 may be distributed in a wing-like manner on both sides of the connecting device A30.

[0042] The connection device A30 further includes a receiving portion A330, which is provided on the fixed base A310 and houses an operating member A340, which is used to release the lock between the part A20 and the carrier body A10. The configuration and operating method of the operating member A340 will be described in detail below with reference to Figures 5 to 15.

[0043] 4 shows a bottom perspective view of part A20 according to one embodiment. The lower-left connecting device A30 shows a receiving portion A330 formed as a cutout in the fixed base A310. The main body portion of the operating member A340 is housed in the receiving portion A330 and is slidable relative to the fixed base A310 within the receiving portion A330, with the operating member A340 partially exposed outside the receiving portion A330 when not being operated. Optionally, the operating member A340 matches the shape of the receiving portion A330.

[0044] Inside the engagement groove A320, a connection hole can be provided for drilling additional fixing means, such as a screw or rivet, for additionally fixing the fixing base A310 to the second lever A200 or the cover portion A300.

[0045] The engagement ribs A321 provided in the engagement groove A320 can be seen schematically from the connection device A30 in the upper right of Fig. 4. According to this embodiment, two engagement ribs A321 are arranged laterally in the engagement groove A320, and the width of the engagement ribs A321 corresponds to the width of the engagement portion A101 shown in Fig. 2, thereby performing initial positioning and engagement of the connection device A30.

[0046] 5 to 15 are cross-sectional and perspective views, respectively, of a connection device A30 according to one embodiment.

[0047] FIG. 5 shows a bottom cross-sectional view of portion A of a child carrier according to one embodiment, taken along line II in FIG. 1, from the first lever A100 parallel to the ground in FIG. 1. The first lever A100 is located between the fixed base A310 and the cover A300 of the connecting device A30. The first lever A100 has two engagement portions A101 (in the form of engagement recesses), each of which is fitted with an engagement rib A321, which is shown schematically, and which is provided in the engagement groove A320. When attaching the part A20, if the engagement portions A101 and the engagement ribs A321 are not aligned with each other or an inappropriate part A20 is used, the part A20 cannot be stably attached to the first lever A100. In this application, the engagement between the engagement ribs A321 and the engagement portions A101 is used to avoid the risk of injury to a child due to an unstable connection of the part A20.

[0048] As shown in FIG. 5, the fixed base A310 further includes a slide rail A350 extending perpendicular to the plane of the drawing. When the child carrier is in use, the slide rail A350 optionally extends vertically. Optionally, the slide rail A350 is formed on the inner edge A331 of the receiving portion A330 and protrudes from the inner edge A331 of the receiving portion A330 toward the inside of the receiving portion A330. The operating member A340 may be provided with a slide groove A348 corresponding to the shape of the slide rail A350, and the slide rail A350 is slidably received in the slide groove A348 (e.g., a dovetail fit is formed), so that the operating member A340 can slide along the slide rail A350 in the direction perpendicular to the plane of the drawing and will not be disengaged or removed from the receiving portion A330. Of course, a slide groove may be provided on the fixed base A310 and a slide rail may be provided on the operating member A340, and the technical effect of the operating member A340 sliding relative to the fixed base A310 can be similarly achieved.

[0049] According to this embodiment, the operating member A340 includes a mounting groove A342 arranged in a direction perpendicular to the paper surface in Fig. 5 for mounting and fixing the driving member A370, which will be described in detail later with reference to Fig. 13. According to this embodiment, two mounting grooves A342 are provided, and the slide groove A348 is located between, i.e., on the inside, of the two mounting grooves A342. Optionally, the slide groove A348 may be provided outside the mounting groove A342.

[0050] In this embodiment, the connection device A30 further includes an engagement member A380 for engaging the first lever A100, thereby locking the connection between the part A20 and the carrier body A10 (described below with reference to FIGS. 7 to 10). A movable chamber A311 is provided within the fixed base A310 on the other side of the receiving portion A330 so as to communicate with the engagement groove A320, and the engagement member A380 is movably provided within the movable chamber A311.

[0051] Optionally, a drive member A370 is provided between the engagement member A380 and the operating member A340, and the operating member A340 slides along the slide rail A350 in a direction perpendicular to the plane of the paper, thereby allowing the drive member A370 to switch the engagement member A380 between a locked position and an unlocked position.

[0052] Referring to FIG. 6 , the drive member A370 is a long block, and the engagement member A380 and the operation member A340 are connected to both ends of the drive member A370, respectively. The drive member A370 includes a drive member main body A371, and connection protrusions A373 are provided on both ends of the drive member main body A371. The connection protrusions A373 are column-shaped to facilitate insertion and rotation of the engagement member A380 or the operation member A340, thereby allowing the drive member A370 to rotate relative to the engagement member A380 and / or the operation member A340. Optionally, in this embodiment, both ends of the drive member main body A371 have the same structure and shape, and the engagement member A380 and the operation member A340 are provided with corresponding connection structures. In other embodiments, the both ends of the drive member main body A371 may have different structures and shapes. For example, the connection protrusions A373 may be provided on one end for connection to either the engagement member A380 or the operation member A340, and the other end may be configured with a different connection structure.

[0053] Optionally, two opposing branches A372 are provided at an end of the drive member body A371, and the above-mentioned connecting protrusions A373 are provided on the outer sides of each branch A372. The opposing branches A372 are spaced apart to form a deformation space A374. When connecting the drive member A370 to the engagement member A380 and / or operation member A340, the two opposing branches A372 are pressed toward each other and deformed, and then both ends of the drive member A370 are inserted into the engagement member A380 and / or operation member A340. After the connecting protrusions A373 are in the connecting structures inside the engagement member A380 and / or operation member A340, the branches A372 move away from each other and return to their deformed state, thereby completing the assembly of the drive member A370 with the engagement member A380 and / or operation member A340.

[0054] 7, the assembled state of the driving member A370 and the engaging member A380 is shown by taking the assembly of the driving member A370 and the engaging member A380 as an example. The engaging member A380 is elongated, and one end of the driving member A370 is inserted into the engaging member A380 via the connecting protrusion A373. When the driving member body A371 of the driving member A370 needs to rotate relative to the engaging member A380, the connecting protrusion A373 of the driving member A370 can serve as the rotation point of the connecting hole A384. The assembled structure of the driving member A370 and the engaging member A380 is similar to the assembled structure of the operating member A340 and the driving member A370, and will be described below with reference to FIG. 13.

[0055] The engaging member A380 is provided with a pivot shaft A381 and a positioning boss A382 at both ends, respectively. The pivot shaft A381 and the positioning boss A382 cooperate with the fixed base A310, as will be described in detail later with reference to FIGS.

[0056] Figure 8 shows a plan cross-sectional view of the child carrier along section line II-II in Figure 1 between the engagement groove A320 and the second lever A200, according to one embodiment. The main body of the engagement member A380 is located in the movable chamber A311, and the end of the drive member A370 remote from the engagement member A380 is inserted into the mounting groove A342 of the operating member A340, with the protrusion A335 on this end being located in and rotatable within the connecting hole A343 of the operating member A340. As shown in Figures 9 and 11, the engagement member A380 is movably mounted within the movable chamber A311. Specifically, the engagement member A380 is rotatably mounted within the movable chamber A311, allowing it to be switched between a locked position and an unlocked position.

[0057] 8 also shows a position limiting block A344 that is connected to or formed by part of the operating member A340 and is located in the gap between the two rails A350. Referring to FIG. 10, when the operating member A340 slides downward, the position limiting block A344 can abut against the abutment portion A334 of the receiving portion A330, restricting the operating member A340 from continuing to move downward so as not to separate from the fixed base A310.

[0058] FIG. 9 shows a cross-sectional view of the connection device A30 in the locking position along section line III-III in FIG. 1 at the mounting groove A342 in FIG. 8. FIG. 10 shows the first lever A100 and the joint A130 of the carrier body A10 removed from the cross-sectional view of the connection device A30 in the locking position along section line IV-IV in FIG. 1. FIG. 11 shows a cross-sectional view of the connection device A30 in the unlocking position along section line III-III in FIG. 1 according to one embodiment. FIG. 12 shows a cross-sectional view of the connection device A30 according to yet another embodiment.

[0059] The first lever A100 is slidably accommodated in the upper portion of the engagement groove A320 of the connection device A30, and the second lever A200 is fixedly held between the cover A300 and the fixed base A310. Optionally, the first lever A100 and the second lever A200 are in the same vertical plane, and the first lever A100 can slide up and down along this vertical plane relative to the engagement groove A320 to disengage from the engagement groove A320. In other embodiments, the first lever A100 and the second lever A200 do not have to be in the same vertical plane.

[0060] The receiving portion A330 that houses the operating member A340 of the connection device A30 is located on the side of the fixed base A310 away from the first lever A100 and the second lever A200. The operating member A340 slides up and down along a rail A350 formed by the inner edge A331 of the receiving portion A330 shown in Figures 5 and 8, in a direction parallel to the vertical plane in which the first lever A100 and the second lever A200 are located on the receiving portion A330. In other embodiments, the sliding direction of the operating member A340 does not have to be vertical, and may have a certain inclination relative to the vertical.

[0061] According to this embodiment, one end of the drive member A370 is rotatably connected to the mounting groove A342 of the operating member A340, the drive member body A371 of the drive member A370 passes through the opening A332 shown in Figures 5 and 6, and the other end of the drive member A370 is rotatably connected to the engagement member A380. The engagement member A380 is rotatable within the movable chamber A311 of the fixed base A310.

[0062] 9 and 10 show the connection device A30 in the locked position. When the operating member A340 slides downward, it rotates one end of the driving member A370 and slides it downward. The driving member body A371 rotates clockwise, and the other end of the driving member A370 rotates relative to the engaging member A380, causing the end of the engaging member A380 to protrude from the movable chamber A311 into the engaging groove A320 and abut against the underside of the first lever A100. This prevents the first lever A100 from sliding along the engaging groove A320 and disengaging from the fixed base A310, i.e., locking the first lever A100 in the engaging groove A320.

[0063] 11 shows the unlocked position of the connection device A30. When the user presses the operating member A340 upward so that the upper end of the operating member A340 approaches the upper end A333 of the receiving portion A330, the operating member A340 rotates one end of the driving member A370 and slides it upward, causing the driving member body A371 of the driving member A370 to rotate counterclockwise, and the other end of the driving member A370 to rotate relative to the engaging member A380, causing the end of the engaging member A380 to retract from the locked position shown in FIG. 9 into the movable chamber A311 of the fixed base A310. The first lever A100 then slides downward along the engaging groove A320 relative to the fixed base A310, allowing it to be disengaged from the fixed base A310.

[0064] 9 and 10, a buffer reset member A341 is provided at the upper end of the operating member A340, and the buffer reset member A341 is, for example, a leaf spring, one end of which abuts against the upper end of the operating member A340 and the other end of which is wound around, for example, the second lever A200. Optionally, referring to FIG. 12, the buffer reset member A341 may be provided in a recess A349 formed in the upper end of the operating member A340, and the upper end may be provided as a coil spring limited by a protrusion A335 provided on the upper end A333 of the receiving portion A330.

[0065] A position limiting block A344 is provided at the lower end of the operating member A340, which abuts against an abutment portion A334 formed on the inner edge A331 of the receiving portion A330, thereby regulating the downward sliding stroke of the operating member A340 relative to the fixed base A310 and preventing the operating member A340 from detaching from the fixed base A310.

[0066] When a user presses the operating member A340 to slide it upward, the buffer reset member A341 acts as a buffer to prevent the operating member A340 from forcibly contacting the upper edge A333 of the receiving portion. When a user loosens the operating member A340 or no external force is applied to the operating member A340, the buffer reset member A341 is used to bias the operating member A340 so that the engagement member A380 tends to move to the locked position. In this case, the operating member A340 returns downward due to the elastic force of the buffer reset member A341 until the position limiting block A344 contacts the contact portion A334.

[0067] Figure 13 shows a cross-sectional view of the connection device A30 taken along the cross-sectional line VV in Figure 10. The operating member A340 includes a slide groove A348, and the slide rail A350 of the connection device A30 is located in the slide groove A348 so that the operating member A340 can slide up and down along the slide rail A350. Optionally, there may be two slide grooves A348, or one or more slide grooves A348.

[0068] The operating member A340 also includes a mounting groove A342 and a connecting hole A343 for mounting and positioning the drive member A370. The mounting groove A342 is vertically oriented, and the connecting hole A343 is horizontally oriented and intersects with the mounting groove A342. Referring to FIG. 5 , the mounting groove A342 is substantially flush with an opening A332 formed in the inner edge A331 of the receiving portion A330, and the opening A332 and the mounting groove A342 form a channel for drilling the drive member A370. The main body A371 of the drive member A370 straddles the opening A332 and the mounting groove A342. One end of the drive member A370 is rotatably connected to the operating member A340, and the other end is rotatably connected to the engagement member A380. The mounting groove A342 is formed in a tapered portion at a lower portion near the connecting hole A343, i.e., at least a portion of the mounting groove A342 is formed to converge vertically toward the connecting hole A343. The connecting hole A343 is perpendicular to the mounting groove A342. Optionally, for ease of tooling, the connecting hole A343 penetrates from one side of the operating member A340, i.e., for example, the left connecting hole A343 in FIG. 13 penetrates the left side of the operating member A340.

[0069] When assembling the driving member A370 and the operating member A340, the branch portions A372 of the driving member A370, together with the connecting protrusions A373, are inserted into the mounting groove A342 from above. When they reach the reduced diameter portion, an external force (pushing or pulling the driving member A370 downward) applies a pressing force to the two connecting protrusions A373, causing the two branch portions A372 to compress the deformation space A374. After the connecting protrusions A373 are inserted into the connecting holes A343, the branch portions A372 return to their original shape due to their own elasticity, and the end of the driving member A370 is firmly engaged with the connecting holes A343 of the operating member A340. As described above with reference to Figure 7, the assembly structure of the driving member A370 and the engaging member A380 is similar to that of the operating member A340 and the driving member A370.

[0070] 14 and 15, according to this embodiment, the driving member A370 rotates with the operating member A340 at a pivot point A345. Optionally, the pivot point A345 can be formed by the connecting protrusion A373 of the driving member A370 in FIGS. 6, 7, and 13 and the connecting hole A343 in FIG.

[0071] The engaging member A380 is rotatable within the movable chamber A311 of the fixed base A310. The movable chamber A311 has a guide portion A347 extending vertically upward from its bottom, which divides the lower portion of the movable chamber A311 into a storage portion A346. The pivot shaft A381 of the engaging member A380 is provided, for example, at the bottom of the storage portion A346, allowing the engaging member A380 to rotate around the pivot shaft A381. The movable chamber A311 includes a position limiting wall A312 provided relative to the movable chamber A311, which preferably extends vertically. When the engaging member A380 is in the locked position, the position stop boss A382 abuts against the position limiting wall A312 of the movable chamber A311, and a portion of the engaging member A380 protrudes from the movable chamber A311 and enters the engaging groove A320. When the engaging member A380 is in the unlocked position, the engaging member A380 is fully retracted into the movable chamber A311, and the position stop boss A382 rotates to the other side of the movable chamber A311 and abuts against the other position limiting wall A312 of the movable chamber A311. The position stop boss protrusion A382 cooperates with the pivot shaft A381 and the fixed base A310 to provide more stable and controlled movement of the engaging member A380.

[0072] Optionally, the child carrier of the present application may further include a base portion A140, which shows a child carrier including the base portion A140 according to an embodiment. Different from Fig. 1, the base portion A140 for carrying a child to sleep, play, etc. is provided on the base body A10. The base portion A140 may be fixedly connected to the carrier body A10, for example, to the leg portion A110, in any manner.

[0073] Referring to Fig. 17, the mounting portion A140 is formed by combining a plurality of plate materials A141. Optionally, there are four plate materials A141, and they are of the same type. A connection hole A142 is provided on the edge of each plate material A141 for connecting the plate materials A141. The position of the connection hole A142 can be adjusted as needed.

[0074] Fig. 18 shows the form of a hinged connecting member A143 fixedly connected to the plate material A141 via a connecting hole A142. Fig. 19 shows the structure of the halves of the connecting portion A143, which has a joint A144, one joint A143 for each of the two halves, and the joints A144 of each half are fitted together and penetrated by a rotation shaft (not shown), allowing the two halves to rotate relative to each other, thereby allowing the placing portion A140 to be folded.

[0075] The operating member A340 for unlocking part A20 of the baby bed A1 is configured to slide onto part A20, and when part A20 needs to be unlocked, the direction of force applied to the operating member A340 is the same or nearly the same as the direction of force applied by the user to move part A20 away from the baby bed A1, making the operation more labor-saving and convenient when the user removes part A20. At the same time, the operating member A340 can rotate the engaging member A380 via the driving member A370, and the sliding of the operating member A340 can be converted into the rotation of the engaging member A380 via the driving member A370, resulting in a simple structure.

[0076] In the following, the anti-pinch device of the present application will be described using an example in which the child carrier is a child bed, but it goes without saying that the anti-pinch device of the present application can also be applied to other products that require folding.

[0077] First, referring to Figure 20, Figure 20 is a structural diagram of a child's bed B1'. As shown in Figure 20, the child's bed B1' includes four pillars B12', the upper ends of which are connected to four upper corner fittings B16', and a handrail set B18' (only this handrail set B18' is shown schematically in Figure 20 because the handrail set B18' is covered with a seat cushion) is connected between two of the upper corner fittings B16'. When the bed frame is folded, relative movement occurs between the handrail set B18' and the upper corner fitting B16', and therefore the gap between the handrail set B18' and the upper corner fitting B16' (as shown in the dashed circular portion of Figure 20) poses a risk of the operator's fingers getting caught.

[0078] In order to solve the above problems, the configuration of a children's bed B1 according to the present application will be described in detail with reference to Figures 21 and 22. Here, Figure 21 is a schematic diagram showing the main configuration of the bed frame of a children's bed, and Figure 22 is a schematic diagram showing the overall configuration of a children's bed according to the present application. The children's bed B1 mainly includes a bed frame B10 (shown in Figure 21) and a seat cushion B20 (shown in Figure 22). The bed frame B10 usually includes four posts B12, with four upper corner fittings B16 fixedly connected to the tops of the four posts B12, and the lower ends of the four posts B12 pivotally attached to a bottom tube B14. A handrail set B18 is connected between the two upper corner fittings B16. The support pillars B12, bottom tubes B14, upper corner fittings B16 and handrail set B18 form an approximately rectangular parallelepiped bed frame B10, and the support pillars B12 can be rotatably folded relative to the upper corner fittings B16 and bottom tubes B14, thereby allowing the bed frame B10 to be folded, enabling the child's bed B1 to be accommodated and facilitating temporary storage or transportation of the child's bed B1.

[0079] The handrail set B18 further includes a handrail tube B181 and a handrail seat B182. As shown in Figure 21, taking one side of the bed frame B10 as an example, the handrail seat B182 is located between two adjacent top corner fittings B16, with the two inner ends of the handrail tube B181 pivotally attached to the handrail seat B182 and the two outer ends of the handrail tube B181 pivotally attached to the two adjacent top corner fittings B16, respectively. This allows the handrail tube B181 to be further folded relative to the handrail seat B182, further reducing the folded size of the bed frame B10.

[0080] As described with reference to Fig. 22, the seat B20 of the children's bed B1 according to the present application is arranged to encase the entire bed frame B10. Specifically, the seat B20 includes a side wall seat B22 arranged around the four support posts B12. Optionally, the seat B20 further includes a bottom wall seat B24 arranged around the bottom tube B14. The side wall seat B22 further includes an upper cover portion B223 and a side enclosure portion B221. The upper cover portion B223 may be formed by folding the side wall seat B22 outward over the handrail set B18 and the top corner fitting B16, by folding the handrail set B18 and the top corner fitting B16 from the inside outward, or by folding the handrail set B18 and the top corner fitting B16 from the outside inward. The upper cover part B223 may be an independent member independent of the side wall seat cushion B22, and the upper cover part B223 individually covers the handrail set B18. That is, the lower edge B2231a of the inner part B2231 of the upper cover part B223 may be fixedly connected to the upper edge of the side surrounding part B221. The upper cover part B223 and the side surrounding part B221 may be made of different materials. For example, the side surrounding part B221 may be made of mesh yarn, which can make the children's bed B1 more breathable and comfortable. The upper cover part B223 may also be made of a material such as woven fabric, and may be filled with a filler. As shown in Figure 22, the upper cover part B223 formed by folding simultaneously covers the handrail set B18 and the upper corner fitting B16, and even when the children's bed B1 is folded, the upper cover part B223 covers the gap between the upper corner fitting B16 and the handrail set B18, thereby avoiding the risk of the operator's fingers getting caught in the gap between the handrail set B18 and the upper corner fitting B16.

[0081] Preferably, the side wall seat cloth B22 is folded over the handrail set B18 and the upper corner fitting B16 so that the lower edge B2231a of the inner part B2231 (shown in Figure 23) of the upper cover part B223 is positioned below the lower edge B182a (shown in Figure 21) of the handrail seat B182, thereby making the inner part of the upper cover part B223 relatively neat and beautiful. The positions where the lower edge B2232a of the outer portion B2232 (shown in Figure 23) of the upper cover portion B223 is connected to the top corner fittings B16 on both sides are connected to the side enclosure portion B221, and referring to Figure 23 (only the upper cover portion B223 is shown), the lower edge B2232a of the outer portion B2232 of the upper cover portion B223 is connected to the side enclosure portion B221 via two connecting structures B40, and the remaining portions (i.e., the portion corresponding to the handrail seat B182 and the portion corresponding to the top corner fitting B16) are not connected to the side enclosure portion B221; that is, as shown in Figure 23, a first opening B42 is formed between the two connecting structures B40, and a second opening B44 is formed at a position corresponding to the top corner fitting B16. As shown in FIG. 25, during folding of the child's bed B1, the handrail seat B182 moves downward relative to the side wall seat cloth B22 and is exposed through the first opening B42. That is, the first opening B42 allows the handrail seat B182 to move downward relative to the upper cover portion B223 during folding of the child's bed B1, making folding of the child's bed B1 smoother. The second opening B44 is provided to facilitate attachment of the support B12 and the handrail set B18 to the seat cloth B20. When the child's bed B1 is in the unfolded state, it is preferable for the upper cover portion B223 to completely cover the handrail seat B182 for aesthetic reasons. That is, the lower edge B2232a (shown in FIG. 24) of the outer portion B2232 of the upper cover portion B223 passes under the lower edge B182a (shown in FIG. 21) of the handrail seat B182. In some embodiments, the connecting structure B40 is a sewing thread, but it goes without saying that it may be other connecting structures such as a magic bond.

[0082] However, because the upper cover part B223 is provided, when the child's bed B1 is folded, as the handrail seat B182 moves downward, the lower edge B2231a of the inner side B2231 (shown in FIG. 23) of the upper cover part B223 is likely to get caught on or wrap around the lower edge B182a of the handrail seat B182 (shown in FIG. 21), hindering the downward movement of the handrail seat B182 and further hindering the folding of the handrail set B18, making it impossible to fold the bed frame B10. In particular, in some embodiments, the lower edge B2231a of the inner part B2231 (i.e., the side facing the interior of the child's bed B1) of the upper cover part B223 may also be provided with a connecting member B50 (shown in FIG. 23), such as a fastener, for connecting other accessories to the child's bed B1 (e.g., a hammock). By providing this connecting member B50, the lower edge B2231a of the inner portion of the upper cover portion B223 and the lower edge B182a of the handrail seat B182 are easily caught.

[0083] Therefore, according to one embodiment of the present application, the children's bed B1 of the present application further includes a pinch prevention device B30. In this embodiment, the pinch prevention device B30 is a guide assembly B32, and specifically, as shown in Figures 23 to 26B, which are schematic diagrams showing a children's bed B1 provided with the guide assembly B32 of the present application, the upper cover part B223 is formed by folding back over the handrail set B18 and the top corner fitting B16 via the side wall seat cloth B22, so that the upper cover part B223 essentially has a double structure, and the guide assembly B32 in this embodiment is located inside the double-structured upper cover part B223 and connected to the upper cover part B223 at a position corresponding to the inside of the handrail seat B182, i.e., the guide assembly B32 is connected to the inner part of the upper cover part B223, and the connection may be by sewing, but is not limited to this. Preferably, both lateral ends of the guide assembly B32 are sewn to the upper cover part B223. Specifically, both lateral ends of the guide assembly B32 are completely sewn to the upper cover part B223 along the height direction. Preferably, the guide assembly B32 has elasticity, such as a PE plate. During folding of the children's bed B1, the two handrail tubes B181 of each handrail set B18 rotate relatively in opposite directions, causing wrinkles in the corresponding upper cover part B223. The guide assemblies B32, both ends of which are fixed inside the upper cover part B223, undergo a certain deformation and lift toward the middle, allowing the inner part of the upper cover part B223 to open toward the handrail seat B182 into the children's bed B1. This prevents the lower edge of the upper cover part B223 from interfering with the downward movement of the handrail seat B182, making the folding of the children's bed B1 smoother.

[0084] Figure 24 is a partial view of the inside of the child's bed B1 corresponding to the position of the handrail seat B182, with the child's bed B1 being folded. Figure 25 is a partial view of the outside of the child's bed B1 corresponding to the position of the handrail seat B182, with the child's bed B1 in a fully folded state or nearly folded. As shown in Figures 24 and 25, when the child's bed B1 is folded, the handrail seat B182 moves downward relative to the handrail tube B181. Because the guide assembly B32 is provided, the guide assembly B32 constantly pushes the upper cover portion B223 open during folding, preventing the lower edge B2231a of the inner portion B2231 of the upper cover portion B223 from getting caught on the lower edge B182a of the handrail seat B182, allowing the handrail seat B182 to smoothly slide out of the first opening B42 in the lower edge B2232a of the outer portion B2232 of the upper cover portion B223. The right side of Fig. 24 shows the guide assembly B32 when the child's bed B1 is not folded, and the whole has a rectangular piece structure, while the left side dashed line in Fig. 24 shows the guide assembly B32 when the child's bed B1 is folded, and the guide assembly B32 gradually deforms and arches toward the middle while the child's bed B1 is being folded. Also, as shown in Fig. 25, the handrail seat B182 may be covered with a fabric cover B182b.

[0085] 26A, the folded end of the upper cover portion B223 and the side wall seat cloth B22 are not sewn to each other at the location corresponding to the top corner fitting B16, and therefore, when the children's bed B1 is folded, a second opening B44 is formed in this unsewn location, facilitating the assembly of the bed frame B10 and the seat cloth B20. Also, as shown in FIG. 26A, the upper cover portion B223 is provided with a connecting member B60 at a location corresponding to the top corner fitting B16, and the connecting member B60 is, for example, a connecting hook that is used to connect the upper cover portion B223 to the top corner fitting B16 to prevent accidental separation between the upper cover portion B223 and the top corner fitting B16 during folding and unfolding.

[0086] According to another embodiment, as shown in Fig. 26B, a rectangular shielding sheet B70 made of a woven fabric material can be provided in the area of ​​the opening. According to the embodiment shown in the figure, both side positions of the lower edge of the shielding sheet (excluding the portion where the support post passes through) and both side edges are fixedly connected to the seat cloth B20. The fixing method may be, but is not limited to, sewing. The upper edge of the shielding sheet B70 is not fixed, and as shown with reference to Fig. 22, in order to insert the shielding sheet B70 below the top corner fitting B16, an opening B72 through which the support post B12 passes is provided on the lower edge of the shielding sheet B70 fixed to the seat cloth B22. Also, in order to minimize exposure of the top corner fitting B16, both side positions of the lower edge of the shielding sheet B70 are fixedly connected to the seat portion B22 so that the dimension of the opening at the lower edge of the shielding sheet B70 roughly corresponds to the radial dimension of the support post. In other words, the dimension of the opening is slightly larger than the radial dimension of the support post. Fig. 22 is a schematic diagram of the shielding sheet B70 when the child's bed B1 is in an unfolded state. Because the shielding sheet B70 is provided inside the upper cover portion B223, both sides of the bottom edge and both sides of the shielding sheet B70 are sewn to the seat cloth B20, as shown in Fig. 22. Fig. 22 also shows a sewing thread B71 and an opening B72 through which the support column B12 passes. Specifically, the shielding sheet B70 is provided inside the upper cover portion B223, and is located in a position corresponding to the opening B72. The provision of the shielding sheet B70 prevents fingers from accidentally getting caught in the opening below the top corner fitting B16, thereby improving the safety of the folding operation of the child's bed B1.

[0087] Figure 27 shows the configuration of another embodiment of the guide assembly B32 provided in the child's bed B1 according to the present application. In this embodiment, the guide assembly B32 is fixedly connected to the inside of the handrail seat B182, or optionally, is integrally connected to the inside of the handrail seat B182. The lower edge of the guide assembly B32 extends downward beyond the lower edge of the upper cover part B223, i.e., the lower edge of the guide assembly B32 is exposed through the opening in the upper cover part B223. This prevents the lower edge of the handrail seat B182 from getting caught or wrapped around the lower edge of the upper cover part B223, making it easier to fold the child's bed B1. Other settings are the same as those of the embodiment shown in Figures 23 to 26B.

[0088] In the above description, the guide assemblies B32 are either provided on the inside of the handrail seat B182 (i.e., on the side toward the center of the child's bed B1) or optionally fixed within the upper cover part B223 on the inside corresponding to the handrail seat B182, but this is not limitative. Considering that there is a risk that the lower edge B2232a of the outer part B2232 of the upper cover part B223 may also be caught on the lower edge B182a of the handrail seat, the guide assemblies B32 may be installed on (or correspond to) the outside of the handrail seat B182, and optionally the guide assemblies B32 may be installed on (or correspond to) both the inside and outside of the handrail seat B182 at the same time.

[0089] In some embodiments, referring to Figures 28-29, the children's bed B1 according to the present application may also be provided with a covering assembly B34 that covers the outside of the handrail seat B182 and is located within the upper cover part B223. As shown in Figures 28 and 29, the covering assembly B34 has an overall sleeve structure with openings at both ends for passing the handrail tubes through. This sleeve structure is larger in the middle and smaller at both ends, preventing the covering assembly B34 from sliding relative to the handrail seat B182. The ends of this sleeve structure are sewn to the side of the upper cover part B223 that is closer to the handrail tube, covering the handrail seat B182 and the handrail tube B181, thereby preventing the handrail seat B182 from being exposed outside the upper cover part B223 due to downward movement while the children's bed B1 is being folded, thereby preventing the handrail seat B182 from pinching someone's fingers. This sleeve structure may have elasticity to facilitate folding of the handrail seat B182 and the handrail tube B181, so that the sleeve structure does not pull on the handrail seat B182 and the handrail tube B181 and affect the folding of the entire bed. As shown in Figure 29, either end of the covering assembly B34 may be provided with an openable structure B341, such as adhesive tape, buttons, hooks, etc. In this way, when the sleeve structure needs to be installed, the adhesive tape, buttons, hooks, etc. can be first opened, the end covered on the handrail tube B181, and transferred to the handrail seat B182, and then the adhesive tape, buttons, hooks, etc. can be attached to complete the assembly of the sleeve structure.

[0090] According to this embodiment, the covering assembly B34 completely encases the ends of the two handrail tubes B181 and the handrail seat B182, and during the folding process of the bed frame B10, the covering assembly B34 always completely encases the handrail seat B182 and the connection point between the handrail seat B182 and the handrail tube B181, effectively avoiding grip problems at the point where the user's folding handrail enters the connection point during the folding process, making it safer to use.

[0091] Because the features of the present invention can be embodied in various forms without departing from the characteristics of the invention, the above-described embodiments should be broadly construed as being within the scope defined by the appended claims unless otherwise specified, and therefore, it should also be understood that all changes and modifications that come within the scope and limits of the claims or equivalent schemes of those scopes and limits are to be covered by the appended claims.
