[0011] An embodiment of a device for preventing face-down sleeping will be described below with reference to the drawings. As shown in Fig. 1 to Fig. 10, the device 1 for preventing face-down sleeping comprises a mat 2 that can be wrapped around a mattress M of a baby bed or the like, and an abdominal belt 3 and a crotch belt 11 that restrict the position of the baby to sleeping on its back relative to the mat 2. The abdominal belt 3 and the crotch belt 11 are connected to the mat 2. The device 1 for preventing face-down sleeping prevents the baby from rolling over by engaging the abdominal belt 3 and the crotch belt 11 wrapped around the baby with each other using hook-and-loop fasteners 12 to 15.

[0012] The abdominal belt 3 and the crotch belt 11 are provided with linear fasteners 3d, 11d that detachably connect the fixed parts 3a, 11a and the connecting parts 3b, 11b in intermediate parts 3c, 11c between the fixed parts 3a, 11a fixed by the hook-and-loop fasteners 12-15 and the connecting parts 3b, 11b connected to the mat 2. The linear fasteners 3d, 11d are an example of fasteners.

[0013] The fastener is not particularly limited as long as it can detachably connect the fixing parts 3a, 11a and the connecting parts 3b, 11b of the abdominal belt 3 and the crotch belt 11. For example, examples of the fastener include a wire fastener, a combination of a button and a hole, a snap button, a hook such as a key hook or a spring hook, a magnet, and a hook-and-loop fastener having a smaller connecting area than the hook-and-loop fastener of the fixing part.

[0014] In the device 1 for preventing face-down sleeping of this embodiment, the baby can be removed from the device 1 by simply undoing (opening) the abdominal line fastener 3d and the crotch line fastener 11d, without disengaging the hook-and-loop fasteners 12-15 that engage the abdominal belt 3 and the crotch belt 11 wrapped around the baby. The device 1 for preventing face-down sleeping is configured so that the wrapping length of the abdominal belt 3 and the crotch belt 11 can be adjusted according to the baby's body shape and growth by the hook-and-loop fasteners 12-15, yet the baby can be removed without disengaging the hook-and-loop fasteners 12-15. This eliminates the risk of disturbing the baby's sleep with unpleasant "crunching" sounds that occur when the hook-and-loop fasteners 12-15 are disengaged, making it user-friendly.

[0015] Next, the configuration of each part of the face-down sleeping prevention device 1 will be described. As shown in Fig. 1, the sheet body 4 of the rug 2 is made of, for example, fabric, and is formed in a generally horizontally elongated rectangular shape, with its outer periphery being hemmed. A first hook-and-loop fastener 5 and a second hook-and-loop fastener 6 are sewn to the front surface of one of the left and right leading ends of the sheet body 4 and to the back surface of the other of the left and right leading ends. By engaging the first and second hook-and-loop fasteners 5, 6 with each other, the rug 2 is wrapped around and fixed to the mattress M.

[0016] 2, a belt pocket 7 for attaching the abdominal belt 3 is sewn to the center of the front surface of the sheet body 4. A lateral insertion portion 8 is formed between the belt pocket 7 and the front surface of the sheet body 4. The belt pocket 7 is made of cloth, for example, and is formed in a generally rectangular shape that is long in a direction perpendicular to the left-right direction, and its outer periphery is hemmed.

[0017] The belt pocket 7 is attached to the center of the front surface of the sheet body 4 by only a straight seam 18 near the head and a straight seam 19 near the buttocks. The space between the straight seams 18, 19 forms the insertion part 8. The head-side end and the buttocks-side end of the belt pocket 7 are configured in the shape of a flap. In addition, since the center side of the sheet body 4 is configured by two layers of fabric, the seams 18, 19 of the belt pocket 7 and the seam of the third hook-and-loop fastener 9 are hidden and not exposed on the back side of the sheet body 4.

[0018] 3 and 4, a fourth hook-and-loop fastener 10 is sewn to the back surface of the central portion in the longitudinal direction (left-right direction) of the abdominal belt 3. The central portion in the longitudinal direction of the abdominal belt 3 (where the fourth hook-and-loop fastener 10 is provided) forms the connecting portion 3b. Here, the surface of the abdominal belt 3 that is the upper side when the abdominal belt 3 is attached to the belt pocket 7 is the front surface, and the lower side (the surface facing the mat 2) is the back surface. In this embodiment, the abdominal belt 3 has a configuration in which the left and right abdominal belts 3A and 3B that share the connecting portion 3b are integrally formed.

[0019] 2, a third hook-and-loop fastener 9 that engages with a fourth hook-and-loop fastener 10 of the abdominal belt 3 is sewn to the portion of the surface of the sheet main body 4 that is covered by the belt pocket 7. The abdominal belt 3 is connected to the sheet main body 4 and fixedly held therein by inserting the abdominal belt 3 into the insertion portion 8 and engaging the third hook-and-loop fastener 9 with the fourth hook-and-loop fastener 10.

[0020] A band-shaped crotch belt 11 is sewn to a portion of the belt pocket 7 close to the baby's buttocks. The crotch belt 11 is made of, for example, fabric, and is formed in a generally rectangular shape that is elongated in a direction perpendicular to the left-right direction, and its outer periphery is hemmed. In this embodiment, the base end of the crotch belt 11 is connected and fixed to the mat 2 at a seam 19 of the belt pocket 7 close to the baby's buttocks. The base end of the crotch belt 11 may be sewn to the mat 2 separately from the belt pocket 7.

[0021] The base end of the crotch belt 11 (the end on the belt pocket 7 side) constitutes the connecting portion 11b. Here, when the crotch belt 11 is placed along the floor covering 2 and the mattress M, the surface of the crotch belt 11 that is the upper side is the front surface, and the surface on the lower side (the floor covering 2 side) is the back surface.

[0022] 1 and 2, a seventh hook-and-loop fastener 14 is sewn to the surface of the tip of the crotch belt 11, which engages with a fifth hook-and-loop fastener 12 sewn to the back surface of the tip of the abdominal belt 3B (the other of the left and right abdominal belts). An eighth hook-and-loop fastener 15 is sewn to the back surface of the tip of the crotch belt 11, which engages with a sixth hook-and-loop fastener 13 sewn to the surface of the tip of the abdominal belt 3A (one of the left and right abdominal belts). The tip of the crotch belt 11 (the portion where the seventh and eighth hook-and-loop fasteners 14, 15 are provided) constitutes a fixed portion 11a.

[0023] A crotch side line fastener 11d is attached to an intermediate portion 11c between the tip end (fixing portion 11a) and the base end (connecting portion 11b) of the crotch belt 11, for fastening and detaching the tip end (fixing portion 11a) with the seventh and eighth hook-and-loop fasteners 14, 15. The crotch side line fastener 11d is made of, for example, plastic or metal. In this embodiment, the crotch side line fastener 11d is provided adjacent to the seventh and eighth hook-and-loop fasteners 14, 15.

[0024] 1 to 4, the abdominal belt 3 is made of, for example, fabric, and is formed in a generally rectangular shape that is long from side to side, with its outer periphery being hemmed. The fifth and sixth hook-and-loop fasteners 12, 13 described above are sewn to the back surface of the portion extending from the tip of the other left or right side (abdominal belt 3B) of the abdominal belt 3 to the middle portion in the longitudinal direction, and to the front surface of the tip of one left or right side (abdominal belt 3A). The fourth hook-and-loop fastener 10 described above is sewn to the back surface of the longitudinal center portion (connecting portion 3b) of the abdominal belt 3.

[0025] The tip end of the abdominal belt 3A (the portion to which the sixth hook-and-loop fastener 13 is attached) and the portion of the abdominal belt 3B to which the fifth hook-and-loop fastener 12 is attached form the fixed portion 3a of the abdominal belt 3. In this embodiment, the fifth hook-and-loop fastener 12 extends from the tip end of the abdominal belt 3B to a portion near the fourth hook-and-loop fastener 10 at the midpoint in the length direction, and is provided long along the length direction of the abdominal belt 3B.

[0026] The abdominal belt 3 is provided with a ventral line fastener 3d for attaching and detaching the tip end (fixing part 3a) with the sixth hook-and-loop fastener 13 at an intermediate part 3c between the fixing part 3a and the connecting part 3b on one of the left and right sides (the abdominal belt 3A side). The ventral line fastener 3d is made of, for example, plastic or metal. In this embodiment, the ventral line fastener 3d is provided adjacent to the sixth hook-and-loop fastener 13. Note that a fastener (for example, a line fastener) for separably connecting the fixing part 3a and the connecting part 3b may be provided at an intermediate part 3c between the fixing part 3a and the connecting part 3b on the other of the left and right sides, the abdominal belt 3B.

[0027] When laying an infant using the face-down sleeping prevention device 1, first, as shown in Fig. 5, wrap and secure the mat 2 around the mattress M so that the belt pocket 7 is located in the center of the mattress M. Next, insert the abdominal belt 3 into the insertion part 8 between the belt pocket 7 and the surface of the sheet main body 4, and connect and secure the abdominal belt 3 to the sheet main body 4. Then, lay the infant on the mat 2 so that the crotch belt 11 is located between both legs.

[0028] 6 to 8, the other left or right side of the abdominal belt 3 (abdominal belt 3B), the crotch belt 11, and one left or right side of the abdominal belt 3 (abdominal belt 3A) are wrapped around the baby in the order described, while, for example, the fifth hook-and-loop fastener 12 of the abdominal belt 3B is engaged with the seventh hook-and-loop fastener 14 of the crotch belt 11, and the eighth hook-and-loop fastener 15 of the crotch belt 11 is engaged with the sixth hook-and-loop fastener 13 of the abdominal belt 3A, on the abdomen of the baby. By the above procedure, fitting of the device 1 to prevent prone sleeping on an infant is completed (see Figs. 8 and 9).

[0029] Here, since the hook-and-loop fasteners 12 to 15 have widths in the length and width directions, the wrapping lengths of the abdominal belt 3 and the crotch belt 11 can be adjusted to fit the abdominal and hip sizes of an infant. Also, of the sixth hook-and-loop fastener 13 of the abdominal belt 3A that engages with the eighth hook-and-loop fastener 15 of the crotch belt 11, the portion of the sixth hook-and-loop fastener 13 that protrudes from the crotch belt 11 can also be engaged with the fifth hook-and-loop fastener 12 of the abdominal belt 3B.

[0030] 10, the baby can be removed from the face-down sleeping prevention device 1 simply by removing (opening) the abdominal line fastener 3d and the crotch line fastener 11d without disengaging the fifth and seventh hook-and-loop fasteners 12, 14 or the sixth and eighth hook-and-loop fasteners 13, 15. This eliminates the risk of disturbing the baby's sleep due to the unpleasant "crunching" sound that occurs when the hook-and-loop fasteners 12, 14, 13, 15 between the abdominal belt 3 and the crotch belt 11 are disengaged.

[0031] As can be seen from Fig. 10, after the linear fasteners 3d, 11d are released, the wrapping lengths of the abdominal belt 3 and crotch belt 11 of the device 1 for preventing prone sleeping have already been adjusted. Therefore, when putting the device 1 back on the baby that was removed from it, the abdominal belt 3 and crotch belt 11 can be wrapped around the baby quickly and quietly by simply engaging the linear fasteners 3d, 11d to restrict tossing and turning.

[0032] 5 to 8, the line fasteners 3d, 11d are disposed so as to overlap the abdominal belt 3B. In this embodiment, the abdominal side line fastener 3d is disposed so as to overlap the crotch belt 11 as well.

[0033] That is, the crotch line fastener 11d is provided in the intermediate portion 11c of the crotch belt 11, near the fixed portion 11a so as to overlap the abdominal belt 3 when the abdominal belt 3 and the crotch belt 11 are wrapped around the baby and engaged with each other by the hook-and-loop fasteners 12 to 15. This prevents the crotch line fastener 11d from contacting the abdomen or legs of the baby, ensuring safety and providing a comfortable fit.

[0034] The abdominal line fastener 3d is provided in the middle portion 3c of the abdominal belt 3A (one abdominal belt) near the fixed portion 3a of the abdominal belt 3A so as to overlap the abdominal belt 3B (the other abdominal belt) when the abdominal belt 3 and the crotch belt 11 are wrapped around the baby and engaged with each other by the hook-and-loop fasteners 12 to 15. This prevents the abdominal line fastener 3d from coming into contact with the baby's abdomen, ensuring safety and providing a comfortable fit.

[0035] Furthermore, in this embodiment, when the abdominal belt 3 and the crotch belt 11 are wrapped around the baby and secured, the abdominal line fastener 3d can be made to overlap the crotch belt 11. This makes it possible for the device 1 for preventing prone sleeping to prevent the abdominal line fastener 3d from coming into contact with the baby's legs, thereby improving safety and providing a more comfortable fit.

[0036] In the above embodiment, the crotch belt 11 is sewn to the mat 2, but it may be formed integrally with, for example, the abdominal belt 3. Next, an embodiment in which the abdominal belt 3 and the crotch belt 11 are formed integrally will be described.

[0037] Another embodiment of the device for preventing prone sleeping will be described with reference to Figures 11 to 20. In the description of this embodiment, the same components as those in the above-described embodiment are given the same reference numerals, and the description thereof will be omitted.

[0038] 13 and 14, in the present embodiment, the device 20 for preventing face-down sleeping is integrally formed with a crotch belt 11 in the left-right center of an abdominal belt 3 having left and right abdominal belts 3A and 3B. The abdominal belt 3 and the crotch belt 11 are formed in a roughly T-shape in plan view. The connecting portion 11b of the crotch belt 11 is formed in the portion where the fourth hook-and-loop fastener 10 is provided, and is formed in the same place as the connecting portion 3b of the left and right abdominal belts 3A and 3B.

[0039] The belt pocket 7 is attached to the center of the front surface of the sheet body 4 by only a straight seam 18 near the head and seams 19 at each of the left and right corners near the buttocks. The space between the seams 18, 19 and the space between the left and right seams 19 form the insertion section 8. In other words, the insertion section 8 between the sheet body 4 and the belt pocket 7 is open on three sides, the left and right and the buttocks side.

[0040] When connecting the abdominal belt 3 and the crotch belt 11 to the mat 2, one of the abdominal belts 3A, 3B and the crotch belt 11 are inserted into the insertion part 8 that is open on three sides, the left and right sides and the buttocks side, and the third hook-and-loop fastener 9 and the fourth hook-and-loop fastener 10 are engaged with each other. As a result, the abdominal belt 3 and the crotch belt 11 are connected to the sheet body 4 and fixed and held therein (see also Figures 11 and 12).

[0041] When putting an infant to sleep using the device 20 to prevent prone sleeping, the abdominal belts 3A, 3B and the crotch belt 11 are wrapped around the infant in the same procedure as that for the device 1 to prevent prone sleeping, which has been described with reference to Figs. 5 to 9. Specifically, first, the infant is laid down on the mat 2 so that the crotch belt 11 is positioned between both legs (see Fig. 15). Next, while wrapping the abdominal belt 3B, the crotch belt 11 and the abdominal belt 3A around the infant in the order described above, the seventh hook-and-loop fastener 14 is engaged with the fifth hook-and-loop fastener 12, and the sixth hook-and-loop fastener 13 is engaged with the eighth hook-and-loop fastener 15, and the device 20 to prevent prone sleeping is attached to the infant (see Figs. 16 to 19).

[0042] As shown in Fig. 20, in the device 20 for preventing face-down sleeping, just like the device 1 for preventing face-down sleeping, the infant can be removed by simply undoing (opening) the abdominal line fastener 3d and the crotch line fastener 11d, without disengaging the fifth and seventh hook-and-loop fasteners 12, 14 or the sixth and eighth hook-and-loop fasteners 13, 15. This eliminates the risk of disturbing the infant's sleep due to unpleasant noises that may occur when the hook-and-loop fasteners 12, 14, 13, 15 are disengaged. In other words, the device 20 for preventing face-down sleeping has the same effects and advantages as the device 1 for preventing face-down sleeping.

[0043] In the device 20 for preventing prone sleeping, the sixth hook-and-loop fastener 13 on the abdominal belt 3B is divided into two, left and right, but it may be formed as one piece, or may be divided into three or more pieces. Similarly, each of the hook-and-loop fasteners 9, 10, 12, 14, and 15, which is made up of a single hook-and-loop fastener, may be divided into two or more pieces. This configuration is also applicable to the device 1 for preventing prone sleeping described with reference to Figs. 1 to 10. The size of each of the hook-and-loop fasteners 9, 10, 12 to 15 can be changed as appropriate.

[0044] Although the embodiment has been described above, the present invention is not limited to the above-described embodiment, and can be embodied in various forms. The configuration of each part is not limited to the illustrated embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the configurations described in the above-described embodiment and modified examples (notes, etc.) may be combined, and addition, omission, substitution, and other modifications of the configuration are possible.

[0045] The method of connecting the abdominal belt 3 and the crotch belt 11 to the mat 2 is not particularly limited, and for example, the abdominal belt 3 may be connected to the mat 2 by sewing. In this case, both abdominal belts 3A and 3B may be sewn to the mat 2, or one of the abdominal belts 3A and 3B may be sewn to the mat 2 together with the belt pocket 7, and the other abdominal belt 3A or 3B and the crotch belt 11 may be provided in a substantially L-shape in plan view, and inserted into an insertion portion 8 provided on one of the left and right side edges and the lower edge of the belt pocket 7, thereby connecting the substantially L-shaped abdominal belt 3A or 3B and the crotch belt 11 to the mat 2. The abdominal belts 3A and 3B may be sewn to the mat 2 separately from the belt pocket 7.

[0046] Furthermore, the configuration with the belt pocket 7 allows the abdominal belt 3 and the crotch belt 11 to be connected to the mat 2 without using the hook-and-loop fasteners 9 and 10. Furthermore, the abdominal belts 3A, 3B and the crotch belt 11 may be connected to the mat 2 with separate hook-and-loop fasteners.

[0047] In addition, the order in which the abdominal belts 3A, 3B and the crotch belt 11 are overlapped on the abdomen of the infant in order to engage the abdominal belt 3 and the crotch belt 11 with each other by the hook-and-loop fastener is not limited to the above embodiment. For example, the fastening parts 3a of the abdominal belts 3A, 3B may be overlapped with each other and then the fastening part 11a of the crotch belt 11 may be overlapped, or the fastening part 3a of the abdominal belts 3A, 3B may be overlapped with the fastening part 11a of the crotch belt 11 placed on the abdomen of the infant. In these cases, it goes without saying that hook-and-loop fasteners are appropriately provided to connect the upper and lower fastening parts 3a, 3a with each other or the fastening part 3a and the fastening part 11a.
