Description

Technical Field

[0001] The invention relates to the technical field of baby products, and in particular to a sleeping box. Background Art

[0002] In order to prevent the baby's head from being blown by the wind, a vertical piece is provided at the end of the sleeping box cover adjacent to the baby's head. In order to make the vertical piece stand upright to achieve the windproof effect, most of the current sleeping box covers extend and lengthen the vertical piece, and add fasteners to the ends of the original fabric of the vertical piece or to the webbing connected to the ends of the original fabric of the vertical piece to fasten and fix with the outer side of the sleeping box. The disadvantage of this method is that it will cover the rotating mechanism of the head cover (not conducive to the operation of the canopy rotating mechanism), such as Figure 1 When the fastening piece 1211 of the vertical piece 1210 is fastened and fixed to the outer side of the sleeping box, the vertical piece 1210 completely covers the rotating mechanism of the head cover part 1300.

[0003] Therefore, there is an urgent need for a sleeping box stand that has a simple structure, does not cover the rotating mechanism of the head cover, and can stand very upright.

[0004] In addition, most sleeping boxes currently have an integrally formed plastic shell, which is not convenient for storage and takes up space at home or in the car. Even though there are various foldable sleeping boxes on the market, they are still built on a hard frame such as plastic or metal, which is not convenient for combining with other vehicles (such as carts). Summary of the invention

[0005] The purpose of the present invention is to provide a sleeping box stand piece with a simple structure, which will not cover the rotating mechanism of the head cover and can stand upright. "Stand upright" in this article means that after the sleeping box cover is installed on the sleeping box, the stand piece of the sleeping box cover is almost perpendicular to the cover piece.

[0006] The present invention also aims to provide a foldable sleeping box which can be folded and folded as a whole to facilitate storage and carrying.

[0007] To achieve the above-mentioned purpose, the present invention provides a sleeping box cover, comprising a vertical piece and a cover piece connected together. Before connection, a virtual auxiliary line perpendicular to the longitudinal axis of the vertical piece is extended along the connecting side of the vertical piece. Before connection, the size of the connecting side of the vertical piece is that the outer end of the connecting side of the vertical piece is retracted X centimeters inward toward the opposite side of the connecting side of the vertical piece relative to the auxiliary line, and X is greater than or equal to zero. Before connection, the size of the connecting side of the cover piece is that the center point of the connecting side of the cover piece is retracted Y centimeters inward toward the opposite side of the connecting side of the cover piece along the longitudinal axis of the cover piece, and Y is greater than zero, and YX is greater than or equal to 2 centimeters.

[0137] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0138] See also Figure 2 , Figure 2 It is a schematic diagram of the dimensions of the vertical piece 1110 and the cover piece 1120 before being connected in one embodiment of the present invention. The present invention provides a sleeping box cover 1100, comprising a vertical piece 1110 and a cover piece 1120 connected together. Before connection, a virtual auxiliary line 1113 perpendicular to the longitudinal axis 1112 of the vertical piece 1110 is extended along the connection side 1111 of the vertical piece 1110. Before connection, the dimension of the connection side 1111 of the vertical piece 1110 is that the outer end 11110 of the connection side 1111 of the vertical piece 1110 is retracted X centimeters inward in the direction of the opposite side 1114 of the connection side 1111 of the vertical piece 1110 relative to the auxiliary line 1113, and X is greater than or equal to zero. Before connection, the size of the connection side 1121 of the cover sheet 1120 is that the center point 11210 of the connection side 1121 of the cover sheet 1120 is retracted inward by Y centimeters along the longitudinal axis 1122 of the cover sheet 1120 toward the opposite side 1124 of the connection side 1121 of the cover sheet 1120, where Y is greater than zero, and YX is greater than or equal to 2 centimeters. In other words, before connection, from the overall outline of the vertical sheet 1110, when X is greater than zero, the connection side 1111 of the vertical sheet 1110 is convex (when X is equal to zero, the connection side 1111 of the vertical sheet 1110 is a straight line), and from the overall outline of the cover sheet 1120, the connection side 1121 of the cover sheet 1120 is concave. The orientation "inside" in this article refers to the direction toward the center ("outside" is the opposite direction of "inside"). Unless otherwise specified, the shapes (outlines) and sizes of the vertical sheet 1110 and the cover sheet 1120 in this article are all in the state before connection.

[0139] The vertical piece 1110 and the cover piece 1120 may be connected in a manner known or easily conceivable to a person skilled in the art, such as sewing, bonding, or even welding.

[0140] If the connection side 1111 of the vertical piece 1110 is concave (such as Figure 3 As shown, the connection side 1111 of the vertical piece 1110 is concave, and the connection side 1121 of the cover piece 1120 is concave), which will cause the cover piece 1120 to be arched (uneven) after connection.

[0141] In one embodiment, when X is greater than zero, the connecting side 1111 of the vertical piece 1110 and the connecting side 1121 of the cover piece 1120 are both arc-shaped.

[0142] In one embodiment, the connecting side 1111 of the vertical sheet 1110 and the connecting side 1121 of the cover sheet 1120 are sewn (stitched) together to produce a seam allowance 1130 (eg, Figure 4A shown).

[0143] In one embodiment, the seam allowance 1130 after the vertical piece 1110 and the cover piece 1120 are sewn together is bound by a binding cloth 1131. Figure 4A shown. Figure 4B The stitching 1132 is shown as viewed from the reverse side (the side facing the baby) of the sleep box cover after the hemming is completed. Figure 4C The front side (the side facing away from the baby) of the sleeping box cover after the hemming is completed is shown.

[0144] In one embodiment, the seam allowance 1130 is hemmed and then pressed to fix. Figure 5A Further pressing the seam allowance 1130 after the hemming is to strengthen and fix the hemming. Figure 5B The stitching 1132 is shown as viewed from the reverse side (the side facing the baby) of the sleep box cover after the hemming and re-pressing are completed. Figure 5C The stitch 1132 is shown as seen from the front side (the side facing away from the baby) of the sleeping box cover after the hemming and pressing is completed. Compared with only hemming, if the seam allowance 1130 is hemmed and then pressed, the difference in YX is greater because the vertical piece 1110 will fall down due to the pressing.

[0145] In one embodiment, the seam allowance 1130 is turned and then pressed to fix (eg Fig. 6A As shown), the principle is similar to "fixing by pressing after hemming", so a larger difference of YX is required, so that the vertical piece 1110 is less likely to fall over due to pressing. Figure 6B The stitches 1132 are shown as seen from the reverse side (the side facing the baby) of the sleeping box cover after the seam allowance 1130 has been turned out and then pressed to secure it. Figure 6C The stitches 1132 are shown as seen from the front side (the side facing away from the baby) of the sleeping box cover after the seam allowance 1130 has been turned out and then pressed to secure it.

[0146] In short, if the difference of YX is larger, a larger upright force will be generated after the vertical piece 1110 and the cover piece 1120 are connected, so that the vertical piece 1110 stands upright.

[0147] In one embodiment, a tube wrapping string 1140 is placed inside the edge of the vertical piece 1110, and the tube wrapping string 1140 is wrapped by a sewn tube wrapping cloth 1150, such as Fig. 7A The tube wrapping rope 1140 can make the vertical piece 1110 stand up more obviously. Figure 7B The reverse side (the side facing the baby) of the rear sleeping box cover of the tube pack is shown. Figure 7C The front side (the side facing away from the baby) of the rear sleeping box cover of the tube pack is shown.

[0148] In one embodiment, if Figure 8 As shown, there is a cotton pad 1115 with a thickness of about 9 mm in the vertical piece 1110, and the vertical piece 1110 is pressed with grid lines (the vertical piece 1110 together with the cotton pad 1115 is pressed and divided into several grids to increase the hardness of the vertical piece 1110) so that the vertical piece 1110 stands up more obviously.

[0149] In one embodiment, the seam allowance 1130 is tilted toward the direction of the sleeping box cover facing the baby's head so that the standing piece 1110 stands up more obviously.

[0150] In an experimental test, when X=0, Y is equal to 2 cm, 3 cm, and 4 cm respectively. The result is: the greater the difference between Y and X, the more upright the vertical piece 1110 is.

[0151] In an experimental test, when X=1.5 cm, Y is equal to 2 cm, 3 cm, and 4 cm respectively. The result is that the greater the difference between YX, the more upright the stand 1110. In particular, when X=1.5 cm and Y=2 cm (YX=0.5 cm, the arc of the connecting side 1111 of the stand 1110 and the arc of the connecting side 1121 of the cover 1120 are nearly parallel), the stand 1110 is not upright enough.

[0152] 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. The result is: the greater the absolute value of the difference between Y and X, the more upright the vertical piece 1110 is.

[0153] In one embodiment, if Fig. 9 As shown, the cover sheet 1120 is provided with a zipper 1125 (for example, for opening the zipper 1125 to take out the pad in the cover sheet 1120) at the front side (the side facing away from the baby) adjacent to the vertical sheet 1110, and the width of the opening 1129 for accommodating (sewing) the zipper 1125 at the connection between the cover sheet 1120 and the vertical sheet 1110 is greater than or equal to the width of the zipper 1125 to prevent the zipper head 11250 and the zipper sheet 11251 from being squeezed onto the vertical sheet 1110 after the zipper 1125 is closed, causing the vertical sheet 1110 to deform at that location.

[0154] In one embodiment, if Fig.10As shown, the cover piece 1120 includes a first part 1126 and a second part 1127, the first part 1126 is used to connect with the vertical piece 1110, and the second part 1127 is connected to a skirt piece 1128 for covering the side of the cover piece 1120 (the skirt piece 1128 is used to cover the side of the upper edge of the sleeping box body), and the skirt piece 1128 has an extension section 11280 in the direction of the baby's head (the end of the skirt piece 1128 has an extension section 11280 in the direction of the baby's head), and the seam between the vertical piece 1110 and the cover piece 1120 after being sewn is sewn to the extension section 11280 of the skirt piece 1128.

[0155] Fig.11 yes Fig.10 A three-dimensional picture of the sleeping box cover after it is installed on the sleeping box. Fig.11 As shown, since the skirt piece 1128 and its extension 11280 hang downward (toward the ground) after the sleeping box cover 1100 is installed on the sleeping box, the seam allowance sewn to the extension 11280 of the skirt piece 1128 is fixed in direction by the downward force (toward the ground), making the vertical piece 1110 connected by the seam allowance more rigid. Preferably, there is a skirt piece 1128 on each of the symmetrical sides of the second portion 1127 of the cover piece 1120, and after the vertical piece 1110 is hemmed, the two ends of the seam allowance 1130 are sewn to the extension 11280.

[0156] In one embodiment, a greater difference in YX is desired when the seam allowance 1130 is tilted toward the baby's feet of the sleeping box lid compared to when the seam allowance 1130 is tilted toward the baby's head of the sleeping box lid.

[0157] In one embodiment, the present invention provides a sleeping box cover 1100, wherein the dimension YX before the vertical piece 1110 and the cover piece 1120 are connected is greater than zero, for example, YX=the first dimension, and the seam allowance 1130 after the vertical piece 1110 and the cover piece 1120 are sewn together is only hemmed. Further, the arc of the connecting side 1111 of the front vertical piece 1110 and the arc of the connecting side 1121 of the cover piece 1120 are not parallel. Further, the dimension X before the vertical piece 1110 is connected is greater than zero.

[0158] In one embodiment, the present invention provides a sleeping box cover 1100, wherein the dimension YX before the vertical piece 1110 and the cover piece 1120 are connected is greater than zero, for example, YX=a second dimension, the second dimension is greater than the first dimension, and the seam 1130 after the vertical piece 1110 and the cover piece 1120 are sewn together is hemmed and then fixed by pressing.

[0159] In one embodiment, the present invention provides a sleeping box cover 1100, wherein the dimension YX before the vertical piece 1110 and the cover piece 1120 are connected is greater than zero, for example, YX=a third dimension, wherein the third dimension is greater than the first dimension, and the seam 1130 after the vertical piece 1110 and the cover piece 1120 are sewn together is turned over and then fixed by pressing.

[0160] In one embodiment, the third size is equal to the second size.

[0161] See also Fig. 12A , Fig. 12B and Fig.13 , which is a schematic diagram of the appearance of a foldable sleeping box 2100 according to an embodiment of the present invention at different viewing angles. The foldable sleeping box 2100 of this embodiment includes a bottom 2110, a side wall portion 2120, a head cover portion 2130 and a cover sheet 2140. The side wall portion 2120 includes a first portion, a second portion, a third portion and a fourth portion which are sequentially connected to each other and connected to the bottom 2110 to enclose a receiving space 2S together with the bottom 2110, wherein the first portion and the second portion are opposite, and the third portion and the fourth portion are opposite; the cover sheet 2140 is detachably connected to a portion of the upper edge 2120A of the side wall portion 2120, thereby covering the receiving space 2S. In this embodiment, the first portion and the second portion opposite to each other of the side wall portion 2120 are respectively the head 2122 and the foot 2128 of the foldable sleeping box 2100, and the third portion and the fourth portion opposite to each other of the side wall portion 2120 are respectively the two opposite side portions 2124 and 2126 of the foldable sleeping box 2100.

[0162] The side wall 2120 and the head cover 2130 are jointly formed of an outer layer of fabric 210, an inner layer of fabric 212, and a filling material wrapped between the outer layer of fabric 210 and the inner layer of fabric 212. That is, in this embodiment, the side wall 2120 and the head cover 2130 of the foldable sleeping box 2100 are formed as a whole by the same fabric and filling material. Fig. 12AAs shown in the cross-sectional view of the middle part, the side wall portion 2120 and the head cover portion 2130 of this embodiment are formed by wrapping the filling material with the outer layer of fabric 210 and the inner layer of fabric 212, wherein the filling material can be a stacked multi-layer structure, which includes, for example, but not limited to: a foam upper layer 214, a foam lower layer 216 and a polyethylene (PE) sheet layer 218 sandwiched therebetween. In other embodiments, the filling material can be a stacked multi-layer structure, which includes, for example, but not limited to: at least one foam layer and at least one polyethylene (PE) sheet layer attached to the foam layer. In this embodiment, the PE sheet layer 218 has a certain hardness, which can not only give the foldable sleeping box 2100 the necessary safety, but also help the sleeping box to be shaped and facilitate the overall production of the foldable sleeping box 2100; the foam upper layer 214 and the foam 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, thereby defining a storage space 2S for accommodating infants when unfolded. The cover sheet 2140 is detachably connected to a portion of the upper edge 2120A of the side wall portion 2120, thereby covering the storage 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 a soft foldable sleeping box 2100 of this embodiment.

As described above, the foldable sleeping box 2100 is provided with a plurality of longitudinally extending fold lines 21221-21229, 21281-21285 on its head 2122 and foot 2128. When the foldable sleeping box 2100 is not needed, the user can release part or all of the connection between the cover sheet 2140 and the side wall 2120, and fold the foldable sleeping box 2100 with the central fold lines 21225, 21283 symmetrically folded along its longitudinal axis 2L and overlapped with the cover sheet 2140, thereby reducing the overall volume of the foldable sleeping box 2100 for easy storage.

[0172] See also Fig.15 and Fig.16 , which is a schematic diagram of the appearance of a foldable sleeping box 400 according to another embodiment of the present invention. The foldable sleeping box 2400 of this embodiment has a configuration and structure similar to the aforementioned foldable sleeping box 2100, including a bottom 2410, a side wall 2420, a head cover 2430 and a cover piece 2440, a vertical piece 2442, a carrying strap 2451, 2452, a grip 2453, and a storage portion 2460. Similarly, in this embodiment, the head cover 2430 and the head 2422, the foot and the two opposite side portions (due to the viewing angle, only 2424 is marked in the figure) of the foldable sleeping box 2400 are formed as a whole by the same cloth material and filling material. The side wall 2420 is connected to the bottom 2410, so as to define a storage space 2S for accommodating infants when unfolded. The cover 2440 is detachably connected to a portion of the upper edge 2420A of the side wall 2420, thereby covering the accommodating space 2S. Optionally, the bottom 2410 and the cover 2440 are also made of the same fabric and filling material as the side wall 2420, forming the soft foldable sleeping box 2400 of this embodiment.

[0173] Different from the aforementioned embodiment, in the present embodiment, the fold line portions 24221, 24222, 24223 in the head cover portion 2430 are formed as a laterally extending arc, that is, the plurality of fold line portions 24221, 24222, 24223 cross the entire arc-shaped head cover portion 2430, so that the head cover portion 2430 can be folded toward the accommodating space 2S through the fold line portions 24221, 24222, 24223, and then fit into the inside of the side wall portion 2420. In this embodiment, when the arc-shaped head cover portion 2430 is folded inward toward the accommodating space 2S, the cloth material and filling material constituting the arc-shaped head cover portion 2430 can conform to the inner edge contour of the side wall portion 2420 as a whole; in this way, when the head cover portion 2430 is not needed, the head cover portion 2430 and the side wall portion 2420 can fit together to provide enhanced cushioning protection in the space corresponding to the top of the infant's head, thereby preventing the infant's head from shaking and getting injured during movement.

[0174] See also FIG. 17A to FIG. 17C ,as well as Fig.18 , which is a schematic diagram of the appearance of a foldable sleeping box 3100 at different viewing angles according to an embodiment of the present invention, wherein Fig. 17C The main structure of the foldable sleeping box of the embodiment of the present invention is schematically illustrated.

In other embodiments, the filling material may be a stacked multi-layer structure of different combinations, which may include, for example, but not limited to: at least one foam layer and at least one polyethylene (PE) sheet layer bonded to the foam layer. In the present embodiment, the PE sheet layer 318 has a certain hardness, which not only can give the foldable sleeping box 3100 the necessary safety, but also can help the sleeping box to be shaped and is conducive to the overall production of the foldable sleeping box 3100; the foam outer layer 314 and the foam 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, thereby defining a storage space 3S for accommodating infants and young children when unfolded. The cover sheet 3140 is detachably connected to a portion of the upper edge 3120A of the side wall portion 3120, thereby covering the storage space 3S. Optionally, the bottom portion 3110 and the cover sheet 3140 are also made of the same fabric and filling material as the side wall portion 3120, forming a 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 also include filling materials composed of stacked multi-layer structures of different combinations. For example, only the filling materials in the first side wall portion 3121 and the third side wall portion 3123 serving as the head and foot portions include a PE sheet layer 318.

In addition, in the present embodiment, in the sub-areas 31212-31214 separated by the folding lines 31211-31215, the first side wall portion 3121 extends upward from the bottom 3110 and slightly extends toward the foot (i.e., the third side wall portion 3123) to integrally form the head of the sleeping box, and the filling material also extends integrally in the entire first side wall portion 3121. As described above, when only the head (first side wall portion 3121) is provided with the folding lines 31211-31215, multiple pieces of filling material 31231, 31232 can be provided in the foot (third side wall portion 3123), which not only helps to further enhance the protection of the foldable sleeping box 3100 for infants and young children, but also makes the assembly of the sleeping box 3100 easier. In another embodiment, the amount of filling material in the third sidewall portion 3123 may correspond to the amount of sub-regions 31212 ˜ 31214 defined by the fold line portions 31211 ˜ 31215 in the first sidewall portion 3121 .

[0181] As described above, the foldable sleeping box 3100 further includes a head cover 3130, which is detachably connected to the upper edge 3121A of the first side wall portion 3121 of the side wall portion 3120, so as to at least partially shield the accommodating space 3S when unfolded. In this embodiment, the head cover 3130 is also composed of a cloth material wrapped with a filling material, such as an outer layer of cloth 310, an inner layer of cloth 320, and a filling material sandwiched therebetween, wherein the filling material can be a single layer of foam layer 322 or a multi-layer structure of different compositions, such as Fig. 17B . In the present embodiment, the filling material of the head cover 3130 is selected so that when the head cover 3130 is connected to the upper edge 3121A of the first side wall portion 3121, it can be stably unfolded with the help of the curvature of the upper edge 3121A, thereby providing a sufficient shielding effect for the infant accommodated in the accommodation space 3S. In addition, the outer layer fabric 310 of the head cover 3130 can be selected to be the same as the outer layer fabric 310 of the side wall portion 3120 of the sleeping box 3100, so as to provide an overall consistent and simple appearance when connected to the first side wall portion 3121. Optionally, the inner layer fabric 320 of the head cover 3130 can be selected according to actual needs. For example, based on ventilation considerations, mesh can be selected as the inner layer fabric 320 of the head cover 3130 to provide a more comfortable feeling for the infant in the accommodation space 3S.

[0182] See also Fig.18 and Fig.19 In this embodiment, the head cover 3130 is detachably connected to the first side wall portion 3121 of the foldable sleeping box 3100, and can be detached and separated from the body of the sleeping box 3100 when the sleeping box 3100 is to be stored or carried, that is, it does not hinder the folding and folding of the sleeping box 3100. Fig.18 The head cover portion 3130 is a sheet-like structure and can be bent toward the accommodating space 3S to adaptively fit the inner side of the first side wall portion 3121, as shown in FIG. Fig.19 In addition, the head cover 3130 can be detachably connected to the first side wall portion 3121 by using a variety of methods or connectors; in this embodiment, the head cover 3130 is connected to the first side wall portion 3121 by using a zipper 3132 as a connector, and can be separated from the first side wall portion 3121 when not needed. In other embodiments, the head cover 3130 can also be connected to the first side wall portion 3121 by using other methods or connectors, including but not limited to: snaps, magnetic fasteners, or Velcro.

[0183] In this embodiment, the head cover portion 3130 may also be composed of the same filling material and cloth material as the side wall portion 3120; wherein the PE sheet layer 318 has a certain hardness, which can provide support for the head cover portion 3130, so that in the unfolded state, in addition to being detachably connected to the upper edge 3121A of the first side wall portion 3121 with its lower edge 3130B, the head cover portion 3130 can also maintain a certain rigidity through the hardness of the PE sheet layer 318, so that the upper edge 3130A of the head cover portion 3130 can be propped up and kept away from the upper edge 3121A of the first side wall portion 3121, thereby at least partially shielding the accommodating space.

[0184] The first upper edge 3121A is in an arc shape, so that the head cover 3130 and the first side wall portion 3121 are connected to each other in an arc shape. In this way, the head cover 3130 can be kept propped up to a predetermined height due to the hardness of the PE sheet in the filling material in the unfolded state, so that its upper edge 3130A does not contact the side wall portion 3120 of the foldable sleeping box 3100, and the head cover 3130 is unfolded and propped up to maintain an angle with the side wall portion 3120 (specifically, to maintain an angle with the second side wall portion 3122 and the fourth side wall portion 3124); at the same time, its inner side surface (the surface formed by the inner layer of fabric 312) forms an arc surface with the arc opening facing the accommodating space.

[0185] Since the head cover 3130 has a filling material structure including a foam upper layer 314, a foam lower layer 316 and a PE sheet layer 318 sandwiched therebetween, this material structure gives the head cover 3130 a certain support strength and bendability toughness. Therefore, when the head cover 3130 is not needed, the user (such as a child or a caregiver of an infant) can not only remove the head cover 3130, but also press the head cover 3130 toward the first side wall portion, so that the head cover 3130 can be bent into the accommodation space of the side wall portion 3120 and accommodated therein, forming a folded state. Fig.19As shown, when in the folded state, the head cover 3130 forms an arc surface with its outer side surface (the surface formed by the outer layer fabric 310) in the accommodation space defined by the side wall 3120, and the head cover 3130 is entirely attached to the first side wall portion 3121. As described above, the head cover 3130 of this embodiment is composed of a skin-friendly and soft outer layer fabric 310, an inner layer fabric 312, and a filling material wrapped therein. Therefore, when the head cover 3130 is accommodated in the accommodation space and attached to the first side wall portion 3121, it can also provide a comfortable feeling and a cushioning and shock-absorbing effect for infants and young children accommodated in the foldable sleeping box 3100, and has both storage convenience and improved safety. In addition to the foam layer, the filling material may also be ethylene-vinyl acetate copolymer (EVA) foam material, whose porosity is more conducive to improving the bendability of the head cover 3130, so that the head cover 3130 can fit better with the first side wall portion 3121 in the folded state.

[0186] Return to Reference Fig.17A , Fig. 17B and Fig.18 In this embodiment, the cover sheet 3140 includes a vertical sheet 3142 on one side close to the first side wall portion 3121 (i.e., the head of the sleeping box 3100). The vertical sheet 3142 can be made of the same fabrics 310, 312 and filling material 314 as the side wall portion 3120; or optionally, the filling material of the vertical sheet 3142 can also include a hard sheet, such as, but not limited to, a polyethylene (PE) sheet, so that the vertical sheet 3142 can effectively and stably stand up when the cover sheet 3140 covers the accommodating space 3S, providing a windproof effect for the infant in the accommodating space 3S.

[0187] In the present embodiment, the cover sheet 3140 is connected to a portion of the upper edge 3120A of the side wall portion 3120 through a connecting member 3144 (for example, but not limited to a zipper, a Velcro, a snap button, a magnetic fastener, etc.). Specifically, the cover sheet 3140 is a portion of the upper edge 3122A of the second side wall portion 3122, an upper edge 3123 of the third side wall portion 3123, and a portion of the upper edge 3124A of the fourth side wall portion 3124, so as to cover the accommodation space 3S and maintain the external communication of the space formed by the connection between the head cover portion 3130 and the first side wall portion 3121. As shown in the figure, in the present embodiment, the connecting member 3144 is a zipper, which is arranged on the periphery of the cover sheet 3140 except the vertical sheet 3142, and the cover sheet 3140 can be connected or partially connected to the corresponding part of the side wall portion 3120 through the zipper.

[0188] In this embodiment, the foldable sleeping box 3100 further includes a pair of carrying straps 3151, 3152, which can be formed by webbing fixed to the outside of the foldable sleeping box 3100, for example, fixed to the outside of the side wall 3120, or further fixed to the outside of the bottom 3110. Considering the weight of the infant and the load of the foldable sleeping box 3100, the webbing can be fixed to the outside of the side wall 3120 by sewing or hot pressing. Optionally, the foldable sleeping box 3100 can also include a carrying strap grip 3153, which is detachably connected to the carrying straps 3151, 3152 to provide the user with a comfortable feeling when holding the foldable sleeping box 3100 of this embodiment.

[0189] In the present embodiment, the respective ends of the carrying 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 carrying straps 3151 and 3152 may also be fixed at their respective ends to opposite sides of the side wall portion 3120, that is, the carrying straps 3151 and 3152 respectively cross the foldable sleeping box 3100 and are fixedly connected to the two sides of the side wall portion 3120.

[0190] In this embodiment, the foldable sleeping box 3100 also includes a storage portion 3160, which is arranged on the outside of the side wall portion 3120, and can be used by the user to place a small amount of items, or store the carrying straps 3151, 3152 and the carrying strap grips 3153, and the connecting webbing assembly 3170 (as described below).

[0191] In this embodiment, the foldable sleeping box 3100 further includes a connecting webbing assembly 3170, which is disposed on the outer sides of both sides of the side wall portion 3120 (due to the viewing angle, only one side of the sleeping box can be shown), so that the foldable sleeping box 3100 can be connected to a carrier (such as Fig.21A and Fig.21B The connecting strap assembly 3170 includes a connecting strap 3171, a connecting fastener 3172, and a length adjustment fastener 3173. When the foldable sleeping box 3100 of this embodiment is to be installed on a carrier for movement, the length of the connecting strap 3171 can be adjusted by using the length adjustment fastener 3173 to adapt it to the connection on the carrier and then fastened with the connecting fastener 3172, as will be further described below. Fig.21A and Fig.21B Provide explanation.

[0192] See also Fig. 20, which schematically illustrates the folded state of the foldable sleeping box 3100 of the embodiment of the present invention. As described above, the foldable sleeping box 3100 of the present embodiment is provided with longitudinally extending fold line portions 31211 to 31213 at its head portion (first side wall portion 3122), and a fold line portion may also be provided at the foot portion. When the foldable sleeping box 3100 is not needed, the user can release the connection between the head cover portion 3130 and the first side wall portion 3121, and release part or all of the connection between the cover piece 3140 and the side wall portion 3120, and fold the foldable sleeping box 3100 so that the center fold line portion 31213 is symmetrically folded along its longitudinal axis 3L and overlapped with the cover piece 3140 to reduce the overall volume of the foldable sleeping box 3100 for easy storage. In this embodiment, the head cover 3130 and the cover plate 3140 of the foldable sleeping box 3100 can be completely separated from the foldable sleeping box 3100, and can be stacked and stored together with the sheet or plate-like structures such as the bottom plate 3112 and the pillow 3180, and the folded sleeping box body.

[0193] It is worth noting that in the present embodiment, the head cover portion 3130 has a complete sheet structure, that is, the head cover portion 3130 is a flat single-piece structure. As described above, the upper edge 3130A and the lower edge 3130B of the head cover portion 3130 have an arc profile, and the arc profiles of the two are not the same. Specifically, the lower edge 3130B of the head cover portion 3130 has an arc profile corresponding to the upper edge 3121A of the first side wall portion 3121, so as to be 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 profile with a smaller curvature (i.e., a larger curvature) than the lower edge 3130B, so as to more effectively form an arc surface with the arc opening facing the accommodating space, so as to provide 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 enables the head cover portion 3130 to be maintained at a predetermined height in the unfolded state due to the hardness of the PE sheet in the filling material when connected to the first side wall portion 3121 of the sleeping box, so as to maintain an angle with the side wall portion when unfolded and provide a shielding effect; at the same time, its inner side surface forms an arc surface with the arc opening facing the accommodating space.

[0194] See also Fig.21A and Fig.21B, which schematically illustrates the combined use state of the foldable sleeping box and the carrier according to an embodiment of the present invention. As described above, the foldable sleeping box 3100 of this embodiment includes a connecting webbing assembly 3170 for connecting and fixing the sleeping box 3100 to the cart 3500. In detail, the user (e.g., the caregiver of an infant) adjusts the connecting webbing 3171 to an appropriate length through the length adjustment buckle 3173 of the connecting webbing assembly 3170, and then the connecting webbing 3171 can be looped and abutted against the appropriate connection of the frame 3510; after further adjusting the length of the connecting webbing 3171, the connecting buckle 3172 can be fastened to make the connecting webbing 3171 as a whole in a tensioned state and abut against the frame 3510, so that the foldable sleeping box 3100 is fixed to the seating portion 3530 of the cart 3500. Although not shown, in other embodiments, the foldable sleeping box 3100 may also be provided with a connecting portion on the outer side of the bottom (for example, by means of snaps, magnetic buckles or Velcro, etc.) so as to use its bottom to be fixed to the seating portion 3530 of the cart 3500; in this case, the connecting webbing assembly 3170 can be used as an auxiliary fixing connection to further enhance the connection stability of the foldable sleeping box 3100 to the cart 3500.

[0195] When used in combination with the stroller 3500, the head cover 3130 of the foldable sleeping box 3100 of this embodiment can be used in conjunction with the canopy 3520 of the stroller 3500 to provide appropriate shielding effects for infants and young children in the sleeping box 3100 in different usage scenarios. For example, when only the head of an infant and young child needs to be shielded, the head cover 3130 of the sleeping box 3100 can be in an unfolded state and the canopy 3520 of the stroller 3500 can be folded to facilitate the user to observe the infant and young child in the sleeping box 3100; when the canopy 3520 of the stroller 3500 needs to be unfolded to largely shield the infant and young child in the sleeping box 3100, the head cover 3130 of the sleeping box 3100 can be folded inwardly to fit the inner side of the side wall 3120 of the sleeping box 3100, or even the head cover 3130 can be removed to prevent the head cover 3130 from interfering with the canopy 3520 and blocking the user's sight.
