Description

Technical Field

[0001] The present invention relates to the technical field of baby supplies, and particularly to a sleeping box.

Background Art

[0002] In order to prevent the baby's head in the sleeping box from being blown by the wind, a standing piece is provided at the end of the sleeping box cover adjacent to the baby's head. In order to raise the standing piece to achieve a wind shielding effect, many current sleeping box covers extend the standing piece and attach an engaging member to the end of the main fabric of the standing piece or the webbing connected to the end of the main fabric of the standing piece, and engage and fix it with the outside of the sleeping box. The disadvantage of this configuration is that it shields the rotation mechanism of the head cover part (which is disadvantageous for the operation of the roof rotation mechanism). As shown in FIG. 1, when the engaging member 1211 of the standing piece 1210 is engaged and fixed with the outside of the sleeping box, the standing piece 1210 completely shields the rotation mechanism of the head cover part 1300.

[0003] Therefore, there is a need for a standing piece of a sleeping box that has a simple structure and can stand up very well without shielding the rotation mechanism of the head cover part.

[0004] Also, currently, most sleeping boxes are composed of an integrally molded plastic housing, which is disadvantageous for storage and occupies space in the house or in the car. Although there are commercially available sleeping boxes that can be folded and stored, they are constructed with a rigid frame such as plastic or metal, which is disadvantageous for connection with other carriers (such as a cart).

Summary of the Invention

[0005] The object of the present invention is to provide a standing piece of a sleeping box that has a simple structure and can stand up very well without obstructing the rotation mechanism of the head cover part. In the present text, "standing up" means that after the sleeping box cover is attached to the sleeping box, the standing piece of the sleeping box cover is substantially perpendicular to the cover sheet.

[0006] Another object of the present invention is to provide a folding type sleeping box that can be folded as a whole and is advantageous for storage and portability.

[0007] One aspect of the present invention provides a sleeping box cover including a standing piece and a cover sheet connected to each other. Before being connected, a virtual auxiliary line perpendicular to the longitudinal axis of the standing piece extends along the connection side of the standing piece.

Mode for Carrying Out the Invention

[0041] In order to explain in detail the technical content and structural features of the present invention, embodiments will be combined and further explained below in conjunction with the drawings.

[0042] Refer to FIG. 2. FIG. 2 is a schematic dimensional diagram before the connection between the upright piece 1110 and the cover sheet 1120 in an embodiment of the present invention. The present invention provides a sleeping box cover 1100 including an upright piece 1110 and a cover sheet 1120 connected to each other. Before being connected, a virtual auxiliary line 1113 perpendicular to the longitudinal axis 1112 of the upright piece 1110 extends along the connection side 1111 of the upright piece 1110. Before being connected, the dimension of the connection side 1111 of the upright piece 1110 is such that the outer end 11110 of the connection side 1111 of the upright piece 1110 shrinks by X centimeters with respect to the auxiliary line 1113 in the direction of the opposite side 1114 of the connection side 1111 of the upright piece 1110, and X is 0 or more. Before being connected, the dimension of the connection side 1121 of the cover sheet 1120 is such that the center point 11210 of the connection side 1121 of the cover sheet 1120 shrinks by Y centimeters in the direction of the opposite side 1124 of the connection side 1121 of the cover sheet 1120 along the longitudinal axis 1122 of the cover sheet 1120, Y is greater than 0, and Y - X is 2 centimeters or more. That is, before connection, when viewed from the overall contour of the upright piece 1110, when X is greater than 0, the connection side 1111 of the upright piece 1110 protrudes outward (when X is equal to 0, the connection side 1111 of the upright piece 1110 is a straight line), and when viewed from the overall contour of the cover sheet 1120, the connection side 1121 of the cover sheet 1120 is recessed inward. The orientation "inward" in this text refers to the central direction ("outward" is the direction opposite to "inward"). Unless otherwise specified, the shapes (contours) and dimensions of the upright piece 1110 and the cover sheet 1120 in this specification are all in the state before connection.

[0043] The connection method between the upright piece 1110 and the cover sheet 1120 may be a connection method known to those skilled in the art or easily conceivable, for example, sewing, adhesion, or even welding.

[0044] When viewed from the overall contour of the upright piece 1110, if the connection side 1111 of the upright piece 1110 is recessed inward (as shown in FIG. 3, the connection side 1111 of the upright piece 1110 is recessed inward and the connection side 1121 of the cover sheet 1120 is recessed inward), the cover sheet 1120 after connection will be in an arched (concave-convex) shape.

[0045] In one embodiment, when X is greater than 0, both the connection side 1111 of the standing piece 1110 and the connection side 1121 of the cover sheet 1120 are arc-shaped.

[0046] In one embodiment, the connection side 1111 of the standing piece 1110 and the connection side 1121 of the cover sheet 1120 are stitched (sewn) to generate a seam allowance 1130 (shown in FIG. 4A).

[0047] In one embodiment, as shown in FIG. 4A, the seam allowance 1130 after stitching the standing piece 1110 and the cover sheet 1120 is bordered by a border cloth 1131. FIG. 4B shows the pins 1132 as viewed from the back surface (the surface facing the baby) of the sleeping box cover after the bordering is completed. FIG. 4C shows the front surface (the surface facing away from the baby) of the sleeping box cover after the bordering is completed.

[0048] In one embodiment, after the seam allowance 1130 is bordered as shown in FIG. 5A, it is fixed with a thread. Fixing the seam allowance 1130 after bordering with a thread is to strengthen the fixation of the bordering. FIG. 5B shows the pins 1132 as viewed from the back surface (the surface facing the baby) of the sleeping box cover after being fixed with the bordering thread. FIG. 5C shows the pins 1132 as viewed from the front surface (the surface facing away from the baby) of the sleeping box cover after being fixed with the bordering thread. When the seam allowance 1130 is bordered and then fixed with a thread, the standing piece 1110 will fall due to being fixed with a thread, so the difference between Y - X needs to be larger than that with only bordering the seam allowance 1130.

[0049] In one embodiment, the hem 1130 is turned inside out and then fixed with a thread (as shown in FIG. 6A). Since this is the same principle as "fixed with a thread after hemming", in order to make the standing piece 1110 less likely to fall by fixing it with a thread, it is necessary to increase the Y - X difference. FIG. 6B shows the hem 1132 as seen from the opposite side (the side facing the baby) of the sleeping box cover after the hem 1130 is turned inside out and fixed with a thread, and FIG. 6C shows the hem 1132 as seen from the surface (the side facing away from the baby) of the sleeping box cover after the hem 1130 is turned inside out and fixed with a thread.

[0050] Simply put, when the difference between Y and X is large, a large rising force is generated after the standing piece 1110 and the cover sheet 1120 are connected, causing the standing piece 1110 to rise.

[0051] In one embodiment, as shown in FIG. 7A, a tube - wrapping string 1140 is disposed inside the edge of the standing piece 1110, and the tube - wrapping string 1140 is wrapped by a stitched tube - wrapping cloth 1150. The tube - wrapping string 1140 can make the standing piece 1110 rise more prominently. FIG. 7B is a view showing the back surface (the surface facing the baby) of the sleeping box cover after being tube - covered. FIG. 7C shows the surface (the surface facing away from the baby) of the sleeping box cover after being tube - covered.

[0052] In one embodiment, as shown in FIG. 8, there is a cotton liner 1115 with a thickness of about 9 mm inside the standing piece 1110, and the standing piece 1110 is fixed with a thread in a striped pattern (the standing piece 1110 is divided into several grids with a thread together with the entire cotton liner 1115, increasing the hardness of the standing piece 1110), making the standing piece 1110 stand more prominently upright.

[0053] In one embodiment, the hem 1130 is tilted in the direction towards the baby's head of the sleeping box cover in order to make the standing piece 1110 rise more prominently.

[0054] In an experimental test, when X = 0, Y is equal to 2 cm, 3 cm, and 4 cm respectively. As a result, the larger the difference between Y - X, the straighter the standing piece 1110 stands.

[0055] In an experimental test, when X = 1.5 cm, Y is equal to 2 cm, 3 cm, and 4 cm respectively. As a result, the larger the difference between Y - X, the straighter the standing piece 1110 stands. In particular, when X = 1.5 cm and Y = 2 cm (Y - X = 0.5 cm, and the arcs of the connecting side 1111 of the standing piece 1110 and the connecting side 1121 of the cover sheet 1120 are nearly parallel), the rising of the standing piece 1110 is very unstable.

[0056] In an experimental test, when Y = 4.5 cm, X is equal to 5 cm, 2.5 cm, 1.5 cm, and 0.5 cm respectively. As a result, the larger the absolute value of the difference between Y - X, the straighter the standing piece 1110 stands.

[0057] In one embodiment, as shown in FIG. 9, the cover sheet 1120 is provided with a fastener 1125 (for example, to open the fastener 1125 and remove the liner inside the cover sheet 1120) at a position on the front side (the side facing away from the baby) adjacent to the standing piece 1110. The width of the opening 1129 for accommodating (sewing) the fastener 1125 at the connection location between the cover sheet 1120 and the standing piece 1110 is greater than or equal to the width of the fastener 1125 in order to prevent the fastener head 11250 and the fastener sheet 11251 from pressing against the standing piece 1110 and deforming the standing piece 1110 at that position after the fastener 1125 is closed.

[0058] In one embodiment, as shown in FIG. 10, the cover sheet 1120 includes a first portion 1126 for connecting to the standing piece 1110 and a second portion 1127 for connecting to a skirt piece 1128 (the skirt piece 1128 is for shielding the side surface of the upper edge of the sleeping box body) for shielding the side edges of the cover sheet 1120. The skirt piece 1128 has an extension segment 11280 extending in the direction of the baby's head (the end of the skirt piece 1128 has the extension segment 11280 extending in the direction of the baby's head). The standing piece 1110 and the cover sheet 1120 are stitched to the extension segment 11280 of the skirt piece 1128 via a stitched seam allowance.

[0059] FIG. 11 is a perspective view after the sleeping box cover of FIG. 10 is attached to the sleeping box. As shown in FIG. 11, after the sleeping box cover 1100 is attached to the sleeping box, since the skirt piece 1128 and its extension segment 11280 hang downward (in the direction toward the ground), the direction of the seam allowance stitched to the extension segment 11280 of the skirt piece 1128 is fixed by the downward (in the direction toward the ground) force, and the standing piece 1110 connected to the seam allowance becomes stronger. Preferably, there are skirt pieces 1128 on both symmetric sides of the second portion 1127 of the cover sheet 1120, and both ends of the seam allowance 1130 bordering the standing piece 1110 are stitched to the extension segment 11280.

[0060] In one embodiment, when the seam allowance 1130 falls in the direction toward the baby's feet of the sleeping box cover rather than in the direction toward the baby's head of the sleeping box cover, the difference between Y and X needs to be larger.

[0061] In one embodiment, the present invention provides a sleeping box cover 1100. The dimension Y - X before the connection between the standing piece 1110 and the cover sheet 1120 is greater than 0. For example, Y - X = a first dimension. The seam allowance 1130 after the stitching of the standing piece 1110 and the cover sheet 1120 is only processed by hemming. Further, before being connected, the arc of the connection side 1111 of the standing piece 1110 and the arc of the connection side 1121 of the cover sheet 1120 are not parallel. Further, the dimension X of the standing piece 1110 before connection is greater than 0.

[0062] In one embodiment, the present invention provides a sleeping box cover 1100. The dimension Y - X before the connection between the standing piece 1110 and the cover sheet 1120 is greater than 0. For example, Y - X = a second dimension. The second dimension is greater than the first dimension. The seam allowance 1130 after the stitching of the standing piece 1110 and the cover sheet 1120 is hemmed and then fixed with a thread.

[0063] In one embodiment, the present invention provides a sleeping box cover 1100. The dimension Y - X before the connection between the standing piece 1110 and the cover sheet 1120 is greater than 0. For example, Y - X = a third dimension. The third dimension is greater than the first dimension. The seam allowance 1130 after the stitching of the standing piece 1110 and the cover sheet 1120 is turned inside out and then fixed with a thread.

[0064] In one embodiment, the third dimension is equal to the second dimension.

[0065] Refer to FIGS. 12A, 12B, and 13 for a schematic external view of the folding sleeping box 2100 in different perspectives according to an embodiment of the present invention. The folding sleeping box 2100 of this embodiment includes a bottom 2110, side wall portions 2120, a head cover portion 2130, and a cover sheet 2140. The side wall portions 2120 include a first portion, a second portion, a third portion, and a fourth portion that are sequentially connected to each other and connected to the bottom 2110 to surround the accommodation space 2S together with the bottom 2110. Here, the first portion and the second portion face each other, the third portion and the fourth portion face each other, and the cover sheet 2140 is detachably connected to a part of the upper edge 2120A of the side wall portions 2120 to cover the accommodation space 2S. In this embodiment, the opposing first portion and second portion of the side wall portions 2120 are the head portion 2122 and the leg portion 2128 of the folding sleeping box 2100, respectively, and the opposing third portion and fourth portion of the side wall portions 2120 are the two opposing side portions 2124 and 2126 of the folding sleeping box 2100, respectively.

[0066] The side wall portion 2120 and the head cover portion 2130 are composed of an outer layer fabric 210, an inner layer fabric 212, and a filling material covered between the outer layer fabric 210 and the inner layer fabric 212. That is, in this embodiment, the side wall portion 2120 and the head cover portion 2130 of the foldable sleeping box 2100 are integrally formed from the same fabric and filling material. Specifically, as shown in the partial cross-sectional view of FIG. 12A, the side wall portion 2120 and the head cover portion 2130 of this embodiment are configured by covering a filling material with an outer layer fabric 210 and an inner layer fabric 212. Here, the filling material may be, for example, a laminated multi-layer structure including a foamed sponge upper layer 214, a foamed sponge lower layer 216, and a polyethylene (PE) sheet layer 218 interposed therebetween, but is not limited thereto. In other embodiments, the filling material may be, for example, but not limited to, a laminated multi-layer structure including at least one foamed sponge layer and at least one polyethylene (PE) sheet layer in contact with the foamed sponge layer. In this embodiment, the PE sheet layer 218 has a certain hardness, can impart the necessary safety to the foldable sleeping box 2100, can assist in shaping the sleeping box, and is advantageous for the overall production of the foldable sleeping box 2100. The foamed sponge upper layer 214 and the foamed sponge lower layer 216 provide comfort and cushioning for the infant accommodated in the accommodation space 2S. The side wall portion 2120 is connected to the bottom portion 2110 and defines an accommodation space 2S for accommodating the infant when deployed. The cover sheet 2140 is a part of the upper edge 2120A detachably connected to the side wall portion 2120 and covers the accommodation space 2S. Optionally, the bottom portion 2110 and the cover sheet 2140 are also made of the same fabric and filling material as the side wall portion 2120 and the head cover portion 2130, forming the soft foldable sleeping box 2100 of this embodiment.

[0067] As shown in FIG. 12A, in this embodiment, a plurality of folded line portions 21221, 21223, 21225, 21227, 21229 extending in the vertical direction are provided on the head portion 2122 and the head cover portion 2130 of the sleeping box 2100. In this embodiment, the folded line portions 21221, 21223, 21225, 21227, 21229 extend vertically from the connection point 2110A between the side wall portion 2120 and the bottom portion 2110 along the head portion 2122 to the head cover portion 2130. Specifically, the plurality of folded line portions 21221, 21223, 21225, 21227, 21229 can be formed by a sewing method, for example, along the longitudinal axis 2L direction of the folding sleeping box 2100 from the head portion 2122 to the head cover portion 2130. The segment of each folded line portion 21221, 21223, 21225, 21227, 21229 located in the head cover portion 2130 has a contour corresponding to the head cover portion 2130 and has a substantially arc shape. In this embodiment, the folding sleeping box 2100 has five folded line portions 21221, 21223, 21225, 21227, 21229. Centered on the folded line portion 21225, the folded line portions 21221, 21229 and the folded line portions 21223, 21227 are symmetrically arranged on both sides of the folded line portion 21225, further separating the head portion 2122 to the head cover portion 2130 into four connected sub-regions 21222, 21224, 21226, 21228. In this embodiment, the configuration of the folded line portions in the folding sleeping box 2100 of this embodiment is described by taking the five folded line portions 21221, 21223, 21225, 21227, 21229 as an example. However, those skilled in the art should understand that the number and position of the installed folded line portions depend on the size and structure of the folding sleeping box 2100 (especially the head cover portion 2130) and are not limited to the form of this embodiment. The space formed by the head cover portion 2130 communicates with the outside through the opening 2131 of the head cover portion 2130, and the folded line portions 21221, 21223, 21225, 21227, 21229 are provided such that the opening 2131 of the head cover portion 2130 has a substantially arc-shaped contour.The broken line portions 21221, 21223, 21225, 21227, 21229 help to stably fix the inner layer fabric material, the outer layer fabric materials 210, 212 and the filling materials 214, 216, and are further helpful for increasing the stiffness of the head cover portion 2130. Further, the foldable sleeping box 2100 can be folded by the installation of the broken line portions 21221, 21223, 21225, 21227, 21229, which will be described below with reference to FIG. 14.

[0068] In this embodiment, a broken line portion 21283 extending in the longitudinal direction is provided on the leg portion 2128 of the foldable sleeping box 2100, for example, by sewing. In this embodiment, the broken line portion 21283 extends in the longitudinal direction along the leg portion 2128 from the connection point 2110A between the side wall portion 2120 and the bottom portion 2110. In this embodiment, between the two side portions 2124, 2126 facing the leg portion 2128, for example, at the end points where the leg portion 2128 has a substantially arc shape, the broken line portions 21281, 21285 are respectively provided, for example, by a sewing method. The broken line portion 21283 of the leg portion 2128 is located on the central longitudinal axis of the leg portion 2128. Centering on the broken line portion 21283, the broken line portions 21281, 21285 are symmetrically arranged on both sides of the broken line portion 21283, and further separate the two sub-regions 21282, 21284 in contact with the leg portion 2128. Similarly, those skilled in the art will understand that the number and position of the installation of the broken line portions depend on the size and structure of the sleeping box 2100 (especially the leg portion 2128) and are not limited to the form of this embodiment. Similarly, the foldable sleeping box 2100 can be folded by the installation of the broken line portion 21283 of the leg portion 2128, which will be described below with reference to FIG. 14.

[0069] As described above, in this embodiment, the head cover portion 2130, the head portion 2122, the two opposing side portions 2124 and 2126, and the leg portion 2128 of the folding sleeping box are integrally formed from the same cloth material and filling material. Specifically, in this embodiment, the inner layer cloth material and the outer layer cloth materials 210 and 212 of the head cover portion 2130, the head portion 2122, the two opposing side portions 2124 and 2126, and the leg portion 2128 of the sleeping box 2100 are integrally formed from the same inner and outer layer cloth materials. However, the folding line portions 21221 to 21229 and 21281 to 21285 separate the entire sleeping box 2100 into a plurality of sub-regions 21222 to 21228, 21282, and 21284, and filling materials corresponding to the sub-regions 21222 to 21228, 21282, and 21284 are provided respectively. Further, in this embodiment, in the sub-regions 21222 to 21228 separated by the folding line portions 21221 to 21229, the head portion 2122 extends upward from the bottom portion 2110 and then extends toward the leg portion 2128 to integrally form the head cover portion 2130, and the filling material also extends integrally from the entire head portion 2122 to the head cover portion 2130.

[0070] In this embodiment, the cover sheet 2140 includes a standing piece 2142 on the side closer to the head cover portion 2130. The standing piece 2142 can be made of the same cloth materials 210 and 212 and filling material 214 as the side wall portion 2120 and the head cover portion 2130, or it can be selectable, and the filling material of the standing piece 2142 may further include a rigid sheet such as a polyethylene (PE) sheet. Thereby, when the cover sheet 2140 covers the accommodation space 2S, the standing piece 2142 can effectively stand up and provide a windproof effect to the infant located in the accommodation space 2S.

[0071] In this embodiment, the cover sheet 2140 is connected to a part of the upper edge 2120A of the side wall portion 2120 via a connecting member 2144 (for example, but not limited to, a fastener, devil's felt, button, etc.). Specifically, the cover sheet 2140 covers the accommodation space S and is the upper edge 2120A of the portion other than the connection with the head cover portion 2130 connected to the side wall portion 2120 so as to maintain the external communication of the space formed by the head cover portion 130. As shown in the figure, in this embodiment, the connecting member 2144 is a fastener provided on the peripheral edge of the cover sheet 2140 excluding the standing piece 2142 as shown in FIG. 13, and the cover sheet 2140 may be connected to the corresponding portion of the side wall portion 2120 via the fastener, or may be connected to the corresponding portion of the side wall portion 2120.

[0072] In this embodiment, the folding sleeping box 2100 may further include a pair of straps 2151 and 2152 configured such that the webbing is fixed to the outside of the folding sleeping box 2100, such as being fixed to the outside of the side wall portion 2120 or further fixed to the outside of the bottom portion 2110. Considering the weight of the infant and the load of the folding sleeping box 2100, the webbing can be fixed to the outside of the side wall portion 2120 by a sewing method or a heat pressing method. Optionally, the folding sleeping box 2100 can further include a strap sleeve 2153 removably connected to the straps 2151 and 2152 to provide comfort for the user to grip the folding sleeping box 2100 of this embodiment.

[0073] In this embodiment, both ends of each of the straps 2151 and 2152 are fixed to the same side of the side wall portion 2120. However, those skilled in the art should understand that the straps 2151 and 2152 may have both ends fixed to the opposite sides of the side wall portion 2120, that is, the straps 2151 and 2152 may be fixedly connected to both sides of the side wall portion 2120 across the folding sleeping box 2100 in the lateral direction.

[0074] In this embodiment, the foldable sleeping box 2100 is provided outside the side wall portion 2120 and further includes a storage portion 2160 where the user can place a small amount of articles.

[0075] Referring to FIG. 14, a folded state of the foldable sleeping box 2100 according to an embodiment of the present invention is schematically shown. As described above, the foldable sleeping box 2100 is provided with a plurality of fold lines 21221-21229, 21281-21285 extending in the vertical direction at its head portion 2122 and leg portion 2128. When it is not necessary to use the foldable sleeping box 2100, the user can release part or all of the connection of the cover sheet 2140 to the side wall portion 2120, and fold the foldable sleeping box 2100 symmetrically along its longitudinal axis 2L with the central fold lines 21225, 21285, 21283, and fold it over the cover sheet 2140, so that the overall volume of the foldable sleeping box 2100 can be reduced to be advantageous for storage.

[0076] Refer to FIGS. 15 and 16, which are schematic external views of the folding sleeping box 400 in another embodiment of the present invention. The folding sleeping box 2400 of this embodiment has the same arrangement and configuration as the folding sleeping box 2100, and includes a bottom 2410, side wall portions 2420, a head cover portion 2430, a cover sheet 2440, standing pieces 2442, straps 2451, 2452, grip sleeves 2453, a storage portion 2460, and the like. Similarly, in this embodiment, the head cover portion 2430 of the sleeping box 2400 and the head portions 2422 and the two side portions (only 2424 is shown in the figure for the viewing angle) facing the legs of the side wall portions 2420 are integrally formed of the same fabric material and filling material. The side wall portions 2420 are connected to the bottom 2410 and define a storage space 2S for accommodating an infant when unfolded. The cover sheet 2440 is a part of the upper edge 2420A detachably connected to the side wall portions 2420 and covers the storage space 2S. Optionally, the bottom 2410 and the cover sheet 2440 are also made of the same fabric material and filling material as the side wall portions 2420, forming the soft folding sleeping box 2400 of this embodiment.

[0077] What is different from the above embodiment is that in this embodiment, the fold lines 24221, 24222, 24223 in the head cover portion 2430 are formed in an arc shape extending in the horizontal direction, and the plurality of fold lines 24221, 24222, 24223 cross the entire arc head cover portion 2430, so that the head cover portion 2430 is folded toward the storage space 2S by the fold lines 24221, 24222, 24223 and further abuts against the inside of the side wall portions 2420. In this embodiment, when the arc head cover portion 2430 is folded inward toward the storage space 2S, the fabric material and the filling material constituting the arc head cover portion 2430 can generally conform to the inner edge contour of the side wall portions 2420. Thus, when the head cover portion 2430 is not needed, by combining the head cover portion 2430 and the side wall portions 2420, enhanced buffer protection can be provided for the space corresponding to the top of the infant's head, and it is possible to avoid the infant's head shaking and getting injured during movement.

[0078] Referring to FIGS. 17A to 17C and FIG. 18, these are schematic external views of the foldable sleeping box 3100 in different perspectives in an embodiment of the present invention. Here, FIG. 17C schematically shows the main body structure of the foldable sleeping box in the embodiment of the present invention. The foldable sleeping box 3100 of this embodiment includes a bottom 3110 and side wall portions 3120. The side wall portions 3120 include a first side wall portion 3121, a second side wall portion 3122, a third side wall portion 3123, and a fourth side wall portion 3124 that are connected to each other in sequence. Here, the first side wall portion 3121 faces the third side wall portion 3123, and the second side wall portion 3122 faces the fourth side wall portion 3124. The upper edges 3121A, 3122A, 3123A, and 3124A of the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 of the side wall portion 3120 jointly form a continuous upper edge 3120A. The upper edge 3120A forms an opening, and the accommodation space 3S communicates with the outside through this opening. When viewed from the top view of the foldable sleeping box 3100, the upper edge 3121A of the first side wall portion 3121 presents an arc-shaped contour. Also, when viewed from the side view of the foldable sleeping box 3100, the upper edge 3121A of the first side wall portion 3121 also presents an arc contour, and has a continuous and gradually changing height 3H that transitions from the upper edge 3121A to the upper edges on both sides of the side wall portion 3120 (that is, the upper edge 3122A of the second side wall portion 3122 and the upper edge 3124A of the fourth side wall portion 3124). In other words, the height 3H of the upper edge 3121A of the first side wall portion 3121 from the bottom 310 of the sleeping box gradually decreases from the first side wall portion 3121 toward the second side wall portion 3122 or the fourth side wall portion 3124.The lower edges 3121B, 3122B, 3123B, and 3124B of the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 respectively form a continuous lower edge 3120B. The side wall portion 3120 is connected from the lower edge 3120B to the bottom 3110, and in the unfolded state, defines an accommodation space 3S surrounded by the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124. On the bottom 3110 of the folding sleeping box 3100, another bottom plate (bottom plate 3112 shown in FIG. 20) can be provided to enhance the strength and support of the bottom of the folding sleeping box 3100. The folding sleeping box 3100 of this embodiment further includes a head cover portion 3130 detachably connected to a first portion of the upper edge 3120A of the side wall portion 3120 (that is, the upper edge 3121A connected to the first side wall portion 3121) to shield at least a part of the accommodation space 3S when unfolded.

[0079] In this embodiment, the opposing first side wall portion 3121 and third side wall portion 3123 of the side wall portion 3120 are the head portion and the leg portion of the folding sleeping box 3100 respectively. When an infant is accommodated in the accommodation space 3S of the folding sleeping box 3100, the head portion and the leg portion of the folding sleeping box 3100 respectively correspond to the direction of the head portion and both legs of the infant. In this embodiment, the head cover portion 3130 is provided at a position close to the head portion of the folding sleeping box 3100 so as to shield the upper half of the infant's body (for example, from above the chest to the head portion) when the infant is accommodated in the accommodation space 3S where the infant can be accommodated, and can provide, for example, a sunshade function for the infant. In this embodiment, the opposing second side wall portion 3122 and fourth side wall portion 3124 of the side wall portion 3120 are two opposing side portions of the folding sleeping box 3100 extending along the longitudinal axis 3L of the folding sleeping box 3100 respectively.

[0080] In one embodiment, the foldable sleeping box 3100 further includes a cover sheet 3140. The cover sheet 3140 is detachably connected to a second portion of the upper edge 3120A of the side wall portion 3120 (i.e., a part of the upper edge 3122A connected to the second side wall portion 3122 of the upper edge 3120A, the upper edge 3123A of the third side wall portion 3123, and a part of the upper edge 3124A of the fourth side wall portion 3124), and covers the accommodation space 3S. In this embodiment, the cover sheet 3140 is provided at the legs close to the foldable sleeping box 3100 so as to cover the lower half of the body of the infant (for example, covering from below the chest to both legs) when the infant is accommodated in the accommodation space 3S where the infant can be accommodated, and helps to appropriately prevent interference from the external environment (for example, wind, rain, vibration, etc.).

[0081] In this embodiment, the side wall portion 3120 is composed of an outer layer fabric material 310, an inner layer fabric material 312, and a filling material covered between the outer layer fabric material 310 and the inner layer fabric material 312. That is, in this embodiment, the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 of the side wall portion 3120 are integrally formed from the same fabric material and filling material. Specifically, as shown in the partial cross-sectional view of FIG. 18, the side wall portion 3120 of this embodiment is configured by covering the filling material with the outer layer fabric material 310 and the inner layer fabric material 312. Here, the filling material may have a laminated multilayer structure. For example, it may include a foamed sponge outer layer 314, a foamed sponge inner layer 316, and a polyethylene (PE) sheet layer 318 interposed therebetween, but is not limited thereto. In other embodiments, the filling material may be, for example, but not limited to, a laminated multilayer structure including at least one foamed sponge layer and at least one polyethylene (PE) sheet layer in contact with the foamed sponge layer. In this embodiment, the PE sheet layer 318 has a certain hardness and can impart the necessary safety to the foldable sleeping box 3100. In addition, it can assist in the standardization of the sleeping box and is advantageous for the overall production of the foldable sleeping box 3100. The foamed sponge outer layer 314 and the foamed sponge inner layer 316 provide comfort and cushioning for the infant accommodated in the accommodation space 3S. The side wall portion 3120 is connected to the bottom portion 3110 and defines an accommodation space 3S for accommodating the infant when unfolded. The cover sheet 3140 is a part of the upper edge 3120A detachably connected to the side wall portion 3120 and covers the accommodation space 3S. Optionally, the bottom portion 3110 and the cover sheet 3140 are also made of the same fabric material and filling material as the side wall portion 3120, forming the soft foldable sleeping box 3100 of this embodiment. In other embodiments, the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 of the side wall portion 3120 may include filling materials having different combinations of laminated multilayer structures. For example, only the filling materials in the first side wall portion 3121 and the third side wall portion 3123, which are the head portion and the leg portion, include the PE sheet layer 318.

[0082] As shown in the figure, in this embodiment, a plurality of folding lines 31211, 31213, 31215 extending in the vertical direction are provided on the head portion of the foldable sleeping box 3100 (that is, the first side wall portion 3121 of the side wall portion 3120). In this embodiment, the folding lines 31211, 31213, 31215 extend vertically from the connection point 3110A between the side wall portion 3120 and the bottom portion 3110 to the upper edge 3121A of the first side wall portion 3121 from the lower edge 3121B of the first side wall portion 3121. Specifically, for example, in the first side wall portion 3121, a plurality of folding lines 31211, 31213, 31215 can be formed along the longitudinal axis 3L direction of the foldable sleeping box 3100. Each folding line 31211, 31213, 31215 has a contour corresponding to the first side wall portion 3121 and has a substantially arc shape. In this embodiment, the first side wall portion 3121 of the foldable sleeping box 3100 has three folding lines 31211, 31213, 31215. Centered on the folding line 31213, the folding line 31211 and the folding line 31215 are symmetrically arranged on both sides of the folding line 31213, further separating the first side wall portion 3121 into two connected sub-regions 31212, 31214. In this embodiment, the configuration of the folding lines in the foldable sleeping box 3100 of this embodiment is described by taking the three folding lines 31211, 31213, 31215 as an example. However, it will be understood by those skilled in the art that the number and position of the folding lines depend on the size and structure of the sleeping box 3100 (especially the first side wall portion 3121) and are not limited to the form of this embodiment. In this embodiment, the first side wall portion 3121 is slightly higher than the other side wall portions of the side wall portion 3120 (that is, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124). Due to the slightly higher first side wall portion 3121 and its folding lines 31211, 31213, 31215, the upper edge 3121A of the first side wall portion 3121 has a substantially arc-shaped contour, which helps to stably fix the inner layer fabric material, the outer layer fabric materials 310, 312 and the filling materials 314, 316, and helps to increase the rigidity of the head portion of the foldable sleeping box 3100.Further, the foldable sleeping box 3100 can be folded along the fold lines 31211, 31213, 31215, and will be described below with reference to FIG. 20.

[0083] Although not shown, similarly, in this embodiment, the person skilled in the art can arrange a fold line extending longitudinally along the entire upper edge 3123A from the connection point 3110A between the side wall portion 3120 and the bottom portion 3110 to the lower edge 3123B of the third side wall portion 3123 so that the fold line extends longitudinally in the leg portion (i.e., the third side wall portion 3123 of the side wall portion 3120) of the foldable sleeping box 3100. Similarly, the arrangement of the fold line in the leg portion also contributes to the folding of the sleeping box 3100 and the stable fixing of the filler. In other embodiments, a fold line extending longitudinally may be selectively provided in the leg portion (i.e., the third side wall portion 3123 of the side wall portion 3120) of the foldable sleeping box 3100. In this case, a plurality (for example, two) of fillers 31231, 31232 are provided in the third side wall portion 3123, the fillers 31231, 31232 are provided adjacent to each other, covered with the fabric material of the third side wall portion 3123, and the third side wall portion 3123 can be folded through the gap 31233 between the fillers 31231, 31232.

[0084] As described above, in this embodiment, the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 of the side wall portion 3120 of the foldable sleeping box 3100 are integrally formed from the same fabric material and filling material. Specifically, in this embodiment, within the first side wall portion 3121, the second side wall portion 3122, the third side wall portion 3123, and the fourth side wall portion 3124 of the sleeping box 3100, the outer layer fabric materials 310, 312 are integrally formed with the same inner layer fabric material and outer layer fabric material. The fold lines 31211, 31213, 31215 separate the entire sleeping box 3100 into a plurality of sub-regions 31212, 31214, and corresponding filling materials are provided in the sub-regions 31212, 31214 respectively. Also, in this embodiment, in the sub-regions 31212 - 31214 separated by the fold lines 31211 - 31215, the first side wall portion 3121 extends upward from the bottom 3110 and then extends substantially toward the leg portion (i.e., the third side wall portion 3123) to integrally form the head portion of the sleeping box, and the filling material also extends integrally within the entire first side wall portion 3121. Further, as described above, when the fold lines 31211 - 31215 are provided only in the head portion (the first side wall portion 3121), a plurality of filling materials 31231, 31232 can be provided within the leg portion (the third side wall portion 3123), which not only helps to further improve the protection of the foldable sleeping box 3100 for infants, but also can simplify the assembly of the sleeping box 3100 at the same time. In another embodiment, the number of filling materials within the third side wall portion 3123 can correspond to the number of sub-regions 31212 - 31214 defined by the fold lines 31211 - 31215 in the first side wall portion 3121.

[0085] As described above, the foldable sleeping box 3100 further includes a head cover portion 3130 detachably connected to the upper edge 3121A of the first side wall portion 3121 of the side wall portion 3120 to shield at least a part of the accommodation space 3S when unfolded. In this embodiment, the head cover portion 3130 is also composed of a cloth material covered with a filling material such as an outer layer cloth material 310, an inner layer cloth material 320, and a filling material sandwiched therebetween. The filling material may be a single-layer foam sponge layer 322 or a multi-layer structure with different compositions of laminated layers, as shown in the partial cross-section of FIG. 17B. In this embodiment, the selection of the filling material of the head cover portion 3130 enables it to be stably unfolded under the assistance of the radian of the upper edge 3121A when the head cover portion 3130 is connected to the upper edge 3121A of the first side wall portion 3121, thereby providing a sufficient shielding effect for the infant accommodated in the accommodation space 3S. Also, the outer layer cloth material 310 of the head cover portion 3130 can be selected in the same way as the outer layer cloth material 310 of the side wall portion 3120 of the foldable sleeping box 3100 to provide a simple appearance that is entirely consistent when connecting to the first side wall portion 3121. Optionally, the inner layer cloth material 320 of the head cover portion 3130 can be selected according to actual needs. For example, based on ventilation considerations, a mesh cloth can be selected as the inner layer cloth material 320 of the head cover portion 3130 to provide a comfortable feeling for the infant in the accommodation space 3S.

[0086] Referring to FIGS. 18 and 19, in this embodiment, the head cover portion 3130 can be detachably separated from the main body of the foldable sleeping box 3100 when attempting to store or carry the foldable sleeping box 3100, as shown in FIG. 18. That is, it is detachably connected to the first side wall portion 3121 of the foldable sleeping box 3100 without interfering with the folding and storage of the foldable sleeping box 3100. The head cover portion 3130 has a sheet-like structure as shown in FIG. 19 and adaptively abuts against the inside of the first side wall portion 3121 so as to be foldable toward the accommodation space 3S. Further, the head cover portion 3130 may be detachably connected to the first side wall portion 3121 by a plurality of methods or connection members. In this embodiment, the head cover portion 3130 is connected to the first side wall portion 3121 with a fastener 3132 as a connection member and can be separated from the first side wall portion 3121 when not needed. In other embodiments, the head cover portion 3130 can also be connected to the first side wall portion 3121 using other methods or connection members including, but not limited to, buttons, magnetic attraction fasteners, or devil's felt.

[0087] In this embodiment, the head cover portion 3130 may be composed of the same filling material and fabric material as the side wall portion 3120. Here, the PE sheet layer 318 has a certain hardness. In addition to the head cover portion 3130 being detachably connected to the upper edge 3121A of the first side wall portion 3121 at its lower edge 3130B in the unfolded state, the hardness of the PE sheet layer 318 can maintain a certain rigidity, and the upper edge 3130A of the head cover portion 3130 can be lifted and separated from the upper edge 3121A of the first side wall portion 3121, providing support for the head cover portion 3130 so that at least a part of the accommodation space can be shielded.

[0088] The first upper edge 3121A presents an arc contour, and between the head cover portion 3130 and the first side wall portion 3121, they are connected to each other with an arc contour. Thereby, the head cover portion 3130 can maintain a predetermined height in the deployed state according to the hardness of the PE sheet in the filling material, the upper edge 3130A does not contact the side wall portion 3120 of the folding sleeping box 3100, and the head cover portion 3130 can expand the support and maintain an angle with the side wall portion 3120 (specifically, maintain an angle between the second side wall portion 3122 and the fourth side wall portion 3124). At the same time, its inner surface (the surface formed by the inner layer fabric 312) forms an arc surface of the arc opening facing the accommodation space.

[0089] Since the head cover part 3130 has a filler structure including an upper foamed sponge layer 314, a lower foamed sponge layer 316, and a PE sheet layer 318 sandwiched therebetween, this material structure imparts a certain support strength and bendable toughness to the head cover part 3130. When it is not necessary to use the head cover part 3130, the user (for example, a caregiver of a child or an infant) can not only remove the head cover part 3130, but also push the head cover part 3130 toward the first side wall part. The head cover part 3130 can be bent and accommodated toward the accommodation space of the side wall part 3120 to form a folded state. As shown in FIG. 19, when in the folded state, the head cover part 3130 forms an arc surface extending outward from the arc opening on its outer surface (the surface formed by the outer layer fabric 310) within the accommodation space defined by the side wall part 3120, and the entire head cover part 3130 is in contact with the first side wall part 3121. As described above, since the head cover part 3130 of this embodiment is composed of a skin-friendly outer layer fabric 310, an inner layer fabric 312, and a filler covered thereon, when the head cover part 3130 is accommodated in the accommodation space and in contact with the first side wall part 3121, it can similarly provide a sense of comfort and a buffering and shock-absorbing effect to the infant accommodated in the folding sleeping box 3100, achieving both improved accommodation convenience and safety. In addition to the foamed sponge layer, an ethylene-vinyl acetate (EVA) foam material can also be adopted as the filler. The porosity it has improves the bendability of the head cover part 3130, enabling the head cover part 3130 to be in contact with the first side wall part 3121 in a folded state.

[0090] Referring to FIGS. 17A, 17B and 18, in this embodiment, the cover sheet 3140 includes a standing piece 3142 on the side close to the first side wall portion 3121 (i.e., the head portion of the sleeping box 3100). The standing piece 3142 can be made in the same way as the side wall portion 3120 with the same cloth materials 310, 312 and the filling material 314, or, optionally, the filling material of the standing piece 3142 may further include a rigid sheet such as a polyethylene (PE) sheet. Thereby, the standing piece 3142 can stand up effectively and stably while the cover sheet 3140 covers the accommodation space 3S, and can provide a windproof effect for the infant located in the accommodation space 3S.

[0091] In this embodiment, the cover sheet 3140 is connected to the upper edge 3120A of a part of the side wall portion 3120 via a connecting member 3144 (for example, a fastener, a devil's felt, a button, a magnetic attraction fastener, etc.). Specifically, the cover sheet 3140 is the upper edge 3122A of a part of the second side wall portion 3122, the upper edge 3123 of the third side wall portion 3123, and the upper edge 3124A of a part of the fourth side wall portion 3124, covers the accommodation space 3S, and maintains the external communication of the space formed by the connection of the head cover portion 3130 and the first side wall portion 3121. As shown in the figure, in this embodiment, the connecting member 3144 is a fastener provided on the periphery of the cover sheet 3140 except for the standing piece 3142, and the cover sheet 3140 may be connected to the corresponding portion of the side wall portion 3120 via the fastener, or may be partially connected.

[0092] In this embodiment, the folding sleeping box 3100 further includes a pair of straps 3151 and 3152, which are formed by fixing the webbing to the outside of the folding sleeping box 3100. For example, they are fixed to the outside of the side wall portion 3120 or further fixed to the outside of the bottom portion 3110. Considering the weight of the infant and the load of the folding sleeping box 3100, the webbing can be fixed to the outside of the side wall portion 3120 by sewing or heat pressing. Optionally, the folding sleeping box 3100 can further include a strap sleeve 3153 removably connected to the straps 3151 and 3152 to provide comfort for the user to grip the folding sleeping box 3100 of this embodiment.

[0093] In this embodiment, both ends of each of the straps 3151 and 3152 are fixed to the same side of the side wall portion 3120. However, those skilled in the art should understand that the straps 3151 and 3152 may have their both ends fixed to the opposite sides of the side wall portion 3120, that is, the straps 3151 and 3152 may be fixedly connected to both sides of the side wall portion 3120 across the folding sleeping box 3100 in the horizontal direction.

[0094] In this embodiment, the folding sleeping box 3100 is provided outside the side wall portion 3120, where the user can place a small amount of items, or further includes a storage portion 3160 (described below) that can store the straps 3151 and 3152, the strap sleeve 3153, and the connecting webbing assembly 3170.

[0095] In this embodiment, the foldable sleeping box 3100 further includes a connecting webbing assembly 3170 provided on both outer sides of the side wall portion 3120 (for the sake of the viewing angle, only one outer side of the sleeping case can be shown). As a result, the foldable sleeping box 3100 is connected to and fixed to one carrier (for example, the cart 3500 shown in FIGS. 21A and 21B). The connecting webbing assembly 3170 includes a connecting webbing 3171, a connecting engagement member 3172, and a length adjustment engagement member 3173. When it is desired to attach and move the foldable sleeping box 3100 of this embodiment to the carrier, the length of the connecting webbing 3171 can be adjusted using the length adjustment engagement member 3173 to fit the connection location on the carrier, and then it can be engaged and fixed with the connecting engagement member 3172. Further description will be made below with reference to FIGS. 21A and 21B.

[0096] Referring to FIG. 20, the folded state of the foldable sleeping box 3100 in the embodiment of the present invention will be schematically described. As described above, the foldable sleeping box 3100 of this embodiment is provided with folding lines 31211 to 31213 extending in the vertical direction on its head portion (the first side wall portion 3122), and folding lines may be similarly provided on the leg portion. When it is not necessary to use the foldable sleeping box 3100, the user can release the connection of the head cover portion 3130 to the first side wall portion 3121, release the connection of the cover sheet 3140 to the side wall portion 3120, and fold the foldable sleeping box 3100 symmetrically along its vertical axis 3L at the central folding line 31213 and stack it with the cover sheet 3140 for folding. The overall volume of the foldable sleeping box 3100 can be reduced to be advantageous for storage. In this embodiment, the head cover portion 3130 and the cover sheet 3140 of the foldable sleeping box 3100 are completely separated from the foldable sleeping box 3100, and can be stored in a stacked manner together with sheet-like or plate-like structures such as the bottom plate 3112 and the pillow portion 3180, and the folded and stored sleeping box body.

[0097] In this embodiment, the head cover portion 3130 has a complete sheet-like structure, that is, the head cover portion 3130 has a flat single sheet-like structure. Also, as described above, the upper edge 3130A and the lower edge 3130B of the head cover portion 3130 have arc-shaped contours, and the arc-shaped contours of the two are not the same. Specifically, the lower edge 3130B of the head cover portion 3130 has an arc-shaped contour corresponding to the upper edge 3121A of the first side wall portion 3121 and is closely connected to the upper edge 3121A of the first side wall portion 3121. The upper edge 3130A of the head cover portion 3130 has an arc-shaped contour with a smaller curvature (i.e., greater bending) than the lower edge 3130B, and can more effectively form an arc surface where the arc opening faces the accommodation space, providing a better shielding effect. In other words, the arc-shaped contour design of the upper edge 3130A and the lower edge 3130B of the head cover portion 3130 can maintain a predetermined height according to the hardness of the PE sheet in the filling material in the unfolded state when the head cover portion 3130 is connected to the first side wall portion 3121 of the foldable sleeping box, support the unfolding and maintain an angle with the side wall portion, and provide a shielding effect. At the same time, its inner surface forms an arc surface of the arc opening facing the accommodation space.

[0098] Refer to FIGS. 21A and 21B which schematically show the usage state of the folding sleeping box according to the embodiment of the present invention in combination with the carrier. As described above, the folding sleeping box 3100 of this embodiment includes a connection webbing assembly 3170 for being connected and fixed to the cart 3500. Specifically, the user (for example, a caregiver of an infant) can sleeve and abut the connection webbing 3171 at an appropriate connection position of the frame 3510 by adjusting the length adjustment engagement member 3173 of the connection webbing assembly 3170 to an appropriate length. Further, after adjusting the length of the connection webbing 3171, the connection engagement member 3172 is engaged so that the entire connection webbing 3171 abuts against the frame 3510 in a tensioned state, and the folding sleeping box 3100 can be fixed to the riding portion 3530 of the cart 3500. Although not shown, in other embodiments, the folding sleeping box 3100 may be provided with a connection portion on the outside of the bottom for fixing to the riding portion 3530 of the cart 3500 using its bottom (for example, using a buckle, a magnetic buckle, a devil's felt, etc.). In this case, the connection webbing assembly 3170 can be used for auxiliary fixed connection, and the connection stability of the folding sleeping box 3100 to the cart 3500 can be further improved.

[0099] When used in combination with the cart 3500, the head cover portion 3130 of the foldable sleeping box 3100 of this embodiment can be used in combination with the roof 3520 of the cart 3500 to provide an appropriate shielding effect for the infant in the foldable sleeping box 3100 in different usage scenarios. For example, when it is necessary to shield only the head portion of the infant, in order to facilitate the user to observe the infant in the sleeping box 3100, the head cover portion 3130 of the sleeping box 3100 can be deployed and the roof 3520 of the cart 3500 can be folded. When it is necessary to deploy the roof 3520 of the cart 3500 to shield a large number of infants in the foldable sleeping box 3100, the head cover portion 3130 of the foldable sleeping box 3100 can be folded inward and abutted against the inner side of the side wall portion 3120 of the foldable sleeping box 3100, and the head cover portion 3130 can be removed so that the head cover portion 3130 does not obstruct the roof 3520 and the user's line of sight.
