Description

TECHNICAL FIELD

The present disclosure relates generally to a sleeping assembly, such as sleeping bags, and more particularly to, a multi-mode secure sleeping bag for young children.

BACKGROUND

A sleeping bag (or bed roll) is a portable bedding complement for a person to sleep with or without a bed. Sleeping bags typically include relatively thick upper and lower panels that provide necessary warmth as well as padding for comfort. Typically, sleeping bags also are constructed with a zipper for opening or closing the sleeping bag for improving insulation.

Traditional sleeping bags are designed for adults and older children, and may not be suitable for younger children or babies. For example, the sleeping bag may contain small articles or loose flaps that might be hazardous for a small child. Thus, prior art sleeping bags have not been specifically structured to enhance comfort and security, especially for young children. Further, a major problem that has been experienced is the sudden unexpected death in infancy (SUDI), sudden infant death syndrome (SIDS), and fatal sleeping accidents. Research states that this risk can be minimized if the children sleep on their back instead of sides or stomach. Therefore, some safe sleeping practices for babies or infants include that the babies should always be on their back while sleeping and no bumper pads or pillows should be used. Conventional sleeping bags provide padding or pillows to restrict sleeping position, but are not suitable for young children or babies for the aforementioned reasons.

Thus, there is a need for sleeping bags for younger children or babies that overcome the aforementioned problems of conventional sleeping bags.

SUMMARY

The present disclosure relates to secure sleeping bags for young children, keeping any child warm and blanket secure, together with carrier portability. The present sleeping bag is attached as one unit, providing convenient carrying, storage, and placement. The present sleeping bag may have pad pockets for keeping bedding secure in portable cribs or playpens. The present sleeping bag may have safety pockets for eliminating loose ends, keeping children safe for example, from blanket being over their head. Further, the present sleeping bag has a detachable safety member that holds the child in a specific position such that the child is always on the back while sleeping and eliminates risk of suffocation due to entire body of the child sliding inside the sleeping bag.

In an embodiment of the present disclosure, a sleeping bag is disclosed. The sleeping bag comprises a bed sheet, a blanket sheet, and a cover sheet attached to each other at a first end and optionally at a portion of two sides adjacent to the first end, and freed at a second end opposite to the first end to form a first sleeping pocket between the bed sheet and the blanket sheet and a second sleeping pocket between the blanket sheet and the cover sheet. The bed sheet comprises at least one of a plurality of reversible pockets and a set of slits for securing the sleeping bag to a support. The cover sheet comprises a reversible pocket at the second end to secure the cover sheet in certain modes of operation. The sleeping bag further comprises a holding member removably attached to the bed sheet and one of the blanket sheet and the cover sheet, wherein the holding member forms openings for a head and hands of a child sleeping in one of the first and second sleeping pockets, to support shoulders of the child such that the child is on the back while sleeping and the child is unable to slide entire body inside one of the first and second sleeping pockets. The sleeping bag also forms a secure blanket configuration to prevent loss of blanket coverage due to the movement of the child.

In some examples, the holding member comprises first and second hand covers to receive hands of the child sleeping in one of the first and second sleeping pockets, to provide comfort and warmth to the hands of the child.

In some examples, an upper surface of the cover sheet comprises a set of securing pockets such that a length of the sleeping bag is adjusted by folding the sleeping bag from the first end at a corresponding securing pocket of the set of securing pockets, and securing the sleeping bag to the support by way of the corresponding securing pocket and the second reversible pocket. Thus, the length of the sleeping bag is adjustable to a height of the child.

In some examples, when the support is a support pad or mattress of a crib, the sleeping bag is secured to the support pad or the mattress by way of the plurality of reversible pockets, and when the support is a harness of a movable object, such as a seat of a moving vehicle or a stroller, the sleeping bag is secured to the harness by way of the set of slits.\

In another embodiment of the present disclosure, a sleeping bag is disclosed. The sleeping bag comprises a bed sheet, a blanket sheet, and a cover sheet attached to each other at a first end and optionally at a portion of two sides adjacent to the first end, and freed at a second end opposite to the first end to form a first sleeping pocket between the bed sheet and the blanket sheet and a second sleeping pocket between the blanket sheet and the cover sheet. The bed sheet comprises at least one of a plurality of reversible pockets and a set of slits for securing the sleeping bag to a support. The cover sheet comprises a reversible pocket at the second end to secure the cover sheet in certain modes of operation. The sleeping bag further comprises a holding member removably attached to one of the bed sheet and the blanket sheet, wherein the holding member forms openings for upper body and legs of a child sleeping in one of the first and second sleeping pockets, to support a lower body of the child such that the child is on the back while sleeping and the child is unable to slide entire body inside one of the first and second sleeping pockets. The sleeping bag also forms a secure blanket configuration to prevent loss of blanket coverage due to the movement of the child.

In yet another embodiment of the present disclosure, a multi-mode sleeping bag is disclosed. The multi-mode sleeping bag comprises at least a bed sheet and a cover sheet attached to each other at a first end and a portion of two sides adjacent to the first end, and freed at a second end opposite to the first end to form a sleeping pocket between the bed sheet and the cover sheet. The bed sheet comprises first and second reversible pockets at the first and second ends, respectively, and the cover sheet comprising a third reversible pocket at the second end that has substantially similar dimensions as the second reversible pocket to allow overlapping of the second reversible pocket by the third reversible pocket in a reversible configuration to secure the cover sheet to the bed sheet. The sleeping bag functions as a multi-mode convertible sleeping bag. For example, a first mode has the sleeping bag placed on a surface, functioning as a sleeping bag. The sleeping bag can be laid directly on a surface, or can be secured to a pad through the reversible pad pockets to provide added support. A second mode has the reversible cover pocket covering the bed sheet and the reversible pad pocket at the second end, with or without a bed pad, functioning as a mattress with no loose flap. A third mode has the cover sheet folded over and the reversible cover pocket covering the bed sheet and the reversible pad pocket at the first end, with or without a bed pad, functioning as a mattress with no loose flap. A fourth mode has the cover sheet and the bed sheet folded over and the reversible pad pocket at the second end covering the bed sheet and the reversible pad pocket at the first end, functioning as a half-size mattress with no loose flap. A fifth mode has the cover sheet and the bed sheet folded twice over and the reversible pad pocket at the second end covering the bed sheet and the reversible pad pocket at the first end, readying for storage. The multi-mode sleeping bag further comprises a holding member attached to at least one of the bed sheet and the cover sheet to hold a child sleeping in the sleeping pocket such that the child is on the back while sleeping and the child is unable to slide entire body inside the first sleeping pocket.

In some examples, the multi-mode sleeping bag can be used as a blanket or comforter. For example, the sleeping bag has slits in the middle to accommodate harness for a stroller or a vehicle seat, functioning as a blanket for the child sitting in the stroller or the vehicle seat with fastened seat belts.

In this embodiment, the present sleeping bag 70 is also used as a conventional sleeping bag with the pad providing an intermediate cushion on the surface 71. For example, the surface 71 can be a hard surface, and the pad 76 can provide a softer surface for the sleeping bag 70. Alternatively, the surface 71 can be a soft surface, and the pad 76 can provide a harder surface for the sleeping bag 70.

FIG. 9D illustrates an exemplary embodiment where the sleeping bag 70 is disposed on a thin pad 76 in a crib 77, such as a portable crib. The pad 76 is tucked in the pockets 75 of the bed sheet 73, to securely attach the sleeping bag 70 to the pad 76, to provide a sleeping environment where the cover (or blanket) 74 is not disturbed by movement of the child. Further, if the holding member 120 or 125 is attached to the sleeping bag the child will be provided extra support such that the child is always on the back while sleeping. In this embodiment, the present sleeping bag 70 is also used as a portable blanket with bed sheet for a crib.

For each child, the used sleeping bag is taken away and a new sleeping bag is attached.

FIG. 9E illustrates an exemplary embodiment where the sleeping bag 70 is disposed on a thick mattress 78 in a crib 79, such as a stationary crib. Stretchable pockets of the bed sheet 73 may be used to accommodate the sleeping bag 70 with the thin pad 76 or the thick mattress 78.

In a second mode, the present sleeping bag can be tucked together to be used as a one-piece mat or blanket, with or without a pad. FIG. 10 illustrates a process for setting a sleeping bag 80 into a one-piece component. As shown in FIG. 10A, the sleeping bag 80 comprises a bed sheet 81 having pockets 84 and 85, and a cover sheet 82 having a reversible pocket 83. In FIG. 10B, the reversible pocket 83 of the cover sheet 82 is reversed 87. In FIG. 8C, the reversed pocket 83 covers the pocket 84 of the bed sheet 81 at the same end to form a one-piece component without any loose portions. FIG. 10 illustrates the sleeping bag 80 with two sheets 81 and 82, but more than two sheets may be used, such as an optional blanket sheet, disposed on the cover sheet 82 or between the cover sheet 82 and the bed sheet 81.

After being tucked together, the sleeping bag 80 may be used as a one-piece mattress, to be rested or slept on. In addition, the one-piece mattress has no loose portion, since the cover sheet 82 has been tucked to the bed sheet 81. FIG. 11A illustrates a tucked one-piece sleeping bag 90 disposed on a surface 91 as a mattress. The surface 91 can be the resting surface of a crib, where the sleeping bag 90 is laid on top of the crib for a child to rest or sleep. FIG. 11B illustrates the tucked one-piece sleeping bag 90 attached to a pad 92 on a surface 91 as a mattress. The bed sheet includes two pockets 93, one on each side. One of the pockets 93 at one end of the bed sheet covers one end of the pad 92. The pockets 93 (at another end of the bed sheet) and 94 (at the same end of the cover sheet) cover the other end of the pad 92. The mattress is resting on a surface, such as a floor surface, or the resting surface of a crib, functioning as a mattress. For example, in a warm day, the sleeping bag 90 may be converted to a mattress for a child to play, rest or sleep on. The converted sleeping bag 90 presents a solid surface to the child, thus preventing any potential hazard when a young child is staying on it, for example, the hazard associated with the sleeping bag, such as loose flap at one end or a sleeping pocket. Alternatively, the one-piece sleeping bag can be used as a blanket instead of a mattress. FIG. 11C illustrates a tucked one-piece sleeping bag attached to a pad in a crib as a mattress. FIG. 11D illustrates a tucked one-piece sleeping bag used as blanket, for example, for a child.

The blanket sheet may also be folded together with the cover sheet 82 to cover the same pocket end 85. Alternatively, the blanket sheet may stay extended and the pocket reversed to cover the pocket end 84.

After a partial fold, the sleeping assembly can be used as a sleeping bag, since the cover sheet is folded over to expose the sleeping pocket. FIG. 13A illustrates a configuration for the folded sleeping bag to function as a sleeping bag. The cover sheet is folded over, and tucked to one pocket of the bed sheet. A child can sleep or rest in the sleeping pocket. As shown, the sleeping bag is positioned on a surface without attaching to a pad. Alternatively, the sleeping bag can be attached to a pad, and then positioned on a surface or in a crib. FIGS. 13B and 13C illustrate different configurations for the folded sleeping bag to function as a mattress. As shown, the sleeping bag is positioned on a surface without a pad, but alternatively, a pad can be attached to the bed pockets. A small child can lie on half of the sleeping bag (FIG. 13B), or a bigger child can lie on the whole sleeping bag. In another embodiment, the folded sleeping bag can function as a blanket.

In a fourth mode, the present sleeping bag can be partially folded to be used as a half-size mat or blanket, for example, a changing pad on a hard surface for infants and small children.
