Description

This application claims priority from U.S. provisional patent application Ser. No. 61/164,809, filed on Mar. 30, 2009, entitled “The Kozysak is a secured sleeping bag, that is made for any portable crib, pack and play, play yard or playpen. Keep any child warm and all blankets secure”, which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

The 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. Sleeping bags also are typically 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.

SUMMARY

The present invention relates to a sleeping assembly, such as a sleeping bag, and particularly 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 can have pad pockets for keeping bedding secure in portable cribs or playpens. The present sleeping bag can have safety pockets for eliminating loose ends, keeping children safe for example, from blanket being over their head.
In an embodiment, the present sleeping bag comprises a bed sheet and a cover sheet secured together at a first end and optionally secured at a portion of the sides to form a sleeping pocket. The bed sheet includes pad pockets at both ends, for example, to secure the sleeping bag to a bed pad. The pockets can have a stretching mechanism incorporated to the fabric to accommodate various sizes of the covering. The present sleeping bag can be attached to a pad or mattress of a crib to form a removable sleeping bag for a child in the crib. The sleeping bag also forms a secure blanket configuration to prevent loss of blanket coverage due to the movement of the child.
In an embodiment, the present sleeping bag comprises a bed sheet and a cover sheet secured together at a first end and optionally secured at a portion of the sides to form a sleeping pocket. The cover sheet includes a reversible cover pocket at a second end, opposite the first end, for example, to secure the cover sheet in certain modes of operation. The bed sheet also includes reversible pad pockets at both ends, for example, to secure the sleeping bag to a bed pad. The pockets can have a stretching mechanism incorporated to the fabric to accommodate various sizes of the covering.
In an embodiment, the present sleeping bag further comprises a blanket sheet disposed between the bed sheet and a cover sheet to provide added comfort. At least one of the blanket sheet and the cover sheet includes a reversible cover pocket at a second end, opposite the first end, for example, to secure the blanket sheet and/or the cover sheet in certain modes of operation.
In an embodiment, the present 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.
In an embodiment, the present sleeping bag can be used as a blanket or comforter. For example, the sleeping bag can have splits in the middle to accommodate hardness for a stroller, functioning as a blanket for a child sitting in a stroller with fastened seat belts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to a sleeping bag, and more particularly, to a portable and secured sleeping bag especially adapted for children, which can easily be transformed into different modes of operation. The present sleeping bag can secure a child or an infant on a sleep surface such as on a floor or on a crib or bed. The present sleeping bag is portable and washable, thus is particularly suited for use in public places, such as a daycare center, where children can provide their own sleeping bags, or the center can provide sanitary sleeping bags for its clients without cross contamination. The present sleeping bag can be used directly on a floor surface, or can be secured to a pad or mat to provide added comfort. The sleeping bags and pads can be stacked within a daycare room, and distributed at nap time. The sleeping bags can be washed between usages. The sleeping bag is designed for security, especially for young children or infants, for example, in the form of no loose flaps, or no strings or small components. In an embodiment, the present sleeping bag provides an infant's sleeping environment as free as possible of suffocation hazards while at the same time insuring the infant is kept in a secure sleeping position.
In an embodiment, the present invention discloses a sleeping bag for use as a bedding complement for a young child or an infant that provides comfort, washability and security, especially for young children. The present sleeping bag can include a cover sheet and/or a blanket sheet to provide additional warmth. In addition, the present sleeping bag is portable, easily stored, and can be easily and quickly arranged for children sleeping.
In an embodiment, the present invention discloses a sleeping bag with attachable components to a solid support with essentially similar dimension, such as a pad or a mattress of a crib, to hold the sleeping bag in place, to prevent shifting of the sleeping bag, and to ensure that the child has adequate blanket coverage without exposure to the ambient, for example, due to the movement of the child.
FIGS. 1A and 1B illustrate a sleeping bag 100 according to an embodiment of the present invention, attached to a pad 118 of substantially similar dimension. The sleeping bag 100 comprises a bed sheet 111 and a cover sheet 112, attached together at a first end 114 and a portion of two sides adjacent the first end 114. The bed sheet and the cover sheet are free at a second opposite end 116A and 116B respectively. The bed sheet and the cover sheet thus form a sleeping bag having a sleeping pocket. The cover sheet 112 can optionally comprise a plurality of connection mechanisms such as snap buttons, hooks, Velcro or other methods of attachment 119 for snapping to mating snap 119 to secure the free end of the cover sheet. The bed sheet 111 comprises attachments 113A and 113B for attaching to a solid support 118. Attachments 113A and 113B on the bed sheet can comprise various configurations, such as pocket configurations for easily attaching to the solid support 118.
FIGS. 2A-2D illustrate different pocket configurations of the bed sheet, showing the back side 120 of the bed sheet. In FIG. 2A, panels 123 are attached to the bed sheet at one end and a portion of sides adjacent to the ends, forming pockets with openings for accepting the support. In FIG. 2B, panels 124 are attached to the bed sheets at corner, forming pockets with openings for accepting the support. In FIG. 2C, strip panels 125 are attached to the bed sheets crossing two opposite ends, forming strips with openings for accepting the support. In FIG. 2D, strip panels 126 are attached to the bed sheets crossing corners, forming strips with openings for accepting the support.
The present sleeping bag can comprise pockets at the cover sheet to function in multiple modes. In an embodiment, a sleeping bag is provided that includes a bed sheet and a cover sheet sewn together to form a sleeping pocket. Reversible pockets are provided on the bed sheet and optionally in the cover sheet for added security and functionality. FIGS. 3A and 3B illustrate a perspective view and a cross section view of a sleeping bag according to an embodiment of the present invention, comprising a bed sheet 11, a cover sheet 12, and reversible pockets 13A, 13B and 13C. The bed sheet 11 and the cover sheet 12 are secured together, for example by sewing, at a first end 14 and a portion of sides 15A adjacent to the first end 14 to form a sleeping pocket. The cover sheet 12 also comprises a reversible cover pocket 13A at a second end 16A, opposite the first end 14. The reversible cover pocket can be formed by sewing a pocket panel to the cover sheet 12 along the second end 16A and a portion of the sides 15B adjacent to the second end 16A to form a pocket opening 17 facing the outer surface of the cover sheet 12. The reversible cover pocket 13A is reversible, meaning it can be turned inside out so that the pocket opening 17 is facing the bed sheet 11. In an embodiment, the cover pocket 13A, after being reversed, can be used to cover the bed sheet 11 to form an integrated layer of bedding. The bed sheet 11 comprises two pad pockets 13C and 13B at the first end 14 and the opposite second end 16B, respectively, with at least one pad pocket reversible, for example, pad pocket 13B. The pad pockets 13B and 13C are designed to securely attach to a pad or mat (not shown), for example, to provide a thicker layer of bedding for added comfort. In addition, pad pocket 13B can be reversible to provide additional functionality, such as tucking to the cover sheet or to the first end 14 of the bed sheet after folded in half. Pad pockets 13B and 13C can be constructed similar to the cover pocket 13A, e.g., sewing along the end and a portion of the sides of the bed sheet 11.
Alternatively, other configurations for attaching the bed sheet to a pad or mattress can be used in place of the reversible pocket, such as pockets, fitted bed sheet or corner pockets. Also, the reversible pocket on the cover sheet is optional, designed for providing multi-mode operations of the sleeping bag.
The bed sheet 11 can be made of a cloth material, such as soft, light weight cotton, other absorbent material, polyester, wool, or fleece, water repellent or resistant materials or natural and synthetic textiles. Alternatively, the bed sheet can be filled with a soft, resilient filler material to provide additional padding. The cover sheet 12 can be made from thicker fabric material with optional fillers, such as a comforter or quilt. For ease of washing, a quilt cover sheet is preferred. In an embodiment, the bed sheet and the cover sheet are joined together to form side and bottom seams, which can be sewn seams or other fabric joining techniques known in the art. Any stitching pattern may be used to join the fabrics, and continuous or intermediate stitching may be used. Additional stitching can be provided across the sheet, such as the cover sheet, to stabilize the filler to prevent potential settling or slippage of the padding material. The pocket can be formed by folding the bed sheet or the cover sheet before joining three outer sides.
In an embodiment, the sleeping bag is solidly constructed, for example, all elements are fabric, so that no small, hard objects can come loose and pose a potential hazard for the child. In addition, there can be no loose flaps or cords, a feature that provides added security for small children. The present sleeping bag can have multiple purposes, and can be easily transportable. In addition, the present sleeping bag can be quickly removed for laundering, allowing for more versatility and usability, especially in the arenas that involve the care of multiple children, such as hospitals, daycare centers or hotels.
The length of sleeping bag is designed to accommodate the length of a child, such as from newborns to about 4-6 year old. Alternatively, the length of the sleeping bag is designed to fit the standard pads or mats, which are approximately six (6) to eight (8) feet. The width of sleeping bag is approximately 2 to 3 feet. The pocket is between 6 to 12 inches deep. The sleeping pocket is between half to ¾ of the length of the sleeping bag. The pockets can have elastic straps or stretchable portions to allow accommodation of variations in pads or mats. The stretchable layer may be cut from a suitable stretchable fabric such as, but not limited to, nylon tricot. It could be part stretchable and part non-stretchable. In either case, it could have means for limiting its stretch.
In an embodiment, the present sleeping bag further comprises a blanket sheet, either disposed between the cover sheet and the bed sheet, or disposed outside the cover sheet. In addition, in some cases, the blanket sheet can include a blanket reversible pocket at the second end opposite the first end. The blanket sheet can provide additional support and comfort for a child when sleeping. In an embodiment, fabrication processes for the sleeping bag with the blanket sheet is similar to those of the sleeping bag without the blanket sheet.
