CRIB SAFETY SHEET/BLANKET

TECHNICAL FIELD

The present invention relates to sheets and blankets for an infant's crib or bed, and more

particularly to an infant sheet and blanket combination adapted to secure an infant in a crib or bed.

BACKGROUND ART

There are a variety of infant blankets and coverings for infants present in the art. In the past many

designs functioned only to keep an infant warm while sleeping. Today much more is known about infant

sleeping patterns and sleeping safety. The concern for infant warmth is now shared with the concern for

infant comfort and safety. Some infants frequently change positions while sleeping, so it is desirable to

make 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.

An additional consideration in infant bedding design is Sudden Infant Death Syndrome (STDS) in

which an apparently healthy infant will expire in a crib for no apparent reason. While the causes of STDS

still remain somewhat a mystery it is thought that sleeping in the prone position may increase the likelihood

of SIDS. A device to maintain an infant in the supine position while sleeping is therefore desirable.

U. S . Pat. No.2,677,834 is typical of the earlier designs. The ' 834 patent discloses a crib blanket

which is secured to the side of a crib with snap together fasteners. The blanket also contains a single strap along the blanket's upper margin for securing an infant to the blanket. This invention will keep a blanket

secure in its relation to the crib but, unlike the present invention, uses only a single strap to secure the infant

under the blanket. Further, the blanket is not attached to the crib sheet.

Other designs such as U. S. Pat. Nos.3 ,845,513 and 4,202,052 disclose fitted garments which

are sewn to crib sheets to restrict the movements of infants. The '513 patent shows a sleeping bag blanket

secured to a bedlinen sheet, the baby being secured in the sleeping bag by a diaper retainer with button

down flaps and by a pull down zipper. The '052 patent shows a sheet with a central pleat having an

opening defined therein to which a jacket maybe attached, the jacket being secured around the infant by

what appear to be button or snap fasteners. No blanket is shown. Infants must be manipulated to be

secured in these garment-type inventions, which often wakes the infant as he or she is being put to bed,

a highly undesirable side effect.

TJ. S . Pat. No .6,301 ,729 discloses one bedding device designed to prevent SID S . It is a pocket

like blanket device which secures an infant between one edge of the pocket and a mattress. This bedding

device does not secure an infant in the same manner as the present invention however, nor does it permit

an infant to be positioned on its side without the risk of the infant moving into the prone position while

sleeping. The '301 invention also does not prevent an infant from squirming downward into the blanket

pocket which could cause a suffocation hazard.

Therefore, it is desirable to have an infant bedding product which will function to keep an infant

covered and warm, is as free as possible of suffocation hazards, is easy to use, is adjustable and will

prevent an infant from moving into the prone sleeping position while still permitting some infant movement.

None of the above inventions and patents, taken either singly or in combination, is seen to describe

the instant invention as claimed. DISCLOSURE OF THE INVENTION

The present invention is a combination safety sheet/blanket. The combination safety sheet/ blanket

has a fitted sheet with a top surface, a bottom surface, a first side and an opposing second side, and two

opposing ends defining pockets for snugly fitting the sheet to a mattress. A first blanket having a top

surface, a bottom surface, and a longitudinal midline, is sewn to the top surface of the fitted sheet along the

midline, defining two blanket halves. A blanket fastening means is provided for temporarily fastening the

two halves of the blanket together when the two halves are wrapped around an infant. A plurality of straps

are provided. Each strap has a first end fixedly attached to the first side of the fitted sheet. Strap fastening

means are provided for removably attaching a second end of each strap to the second side of the fitted

sheet. The fitted sheet may be secured to a mattress and the two halves of the blanket may be wrapped

about an infant and secured by the blanket fastening means in order to retain the infant in the supine

position while sleeping.

Also part of the invention is a combination safety sheet/blanket for infants. The combination safety

sheet/blanket includes a sheet and a first blanket having a top surface, a bottom surface, and a longitudinal

midline. The first blanket is sewn to the top surface of the sheet along the midline, defining two halves.

Blanket fastening means for temporarily fastening the two halves of the first blanket are provided as

described above. The safety sheet/blanket also has means for attaching the sheet to a sleeping surface.

BEST MODES FORCARRYING OUT THEINVENTION

The first embodiment of the present invention is an infant crib safety sheet/blanket 10 which, as

seen in Fig. 1 , is installed on a mattress in a crib, bassinet, or the like. The invention has a blanket portion

12 (blanket) with a front surface and a back surface. The blanket is attached to a fitted sheet portion 14.

The blanket 12 is preferably sewn to the middle of the front surface of the fitted sheet 14 by stitching along

the longitudinal midline of the blanket portion 12, defining two halves of the blanket which may be folded

or wrapped about the infant. When in use, the blanket 12 is wrapped around an infant' s torso and lower extremities (with one side overlapping the other side) so as to keep the infant warm and securely positioned

in the center of the safety sheet/blanket 10 on its back or side. The blanket 12 is held in position around

the infant with four mating strips of hook and loop fastening material (discussed below).

When secured in the safety sheel/blanket an infant retains full motion in its arms and head and some

lateral motion but is unable to roll completely over or to extract itself from the blanket 12. By securing an

infant in this manner there is a lower chance of sudden infant death syndrome, which is normally associated

with infants sleeping in the prone position. The infant has no loose bedding materials upon which to

suffocate, and the infant cannot kick free of its blanket and become cold during sleep.

Fig.2 is a top view of the safety sheet/blanket wrapped around a mattress with the blanket 12 laid

flat against the sheet 14 and the back surface of the blanket 12 coming into contact with the front surface

of the sheet 14. The stitching 20, which secures the blanket 12 to the sheet 14, can be seen in this view.

The hook and loop fastening material 16a, 16b sewn to the front surface of the blanket 12 removably

attaches to corresponding hook and loop fastening material 18a, 18b sewn to the back surface of the

blanket 12. Fig.2 shows two sets of mating hook and loop fasteners (16a with 18a, and 16b with 18b)

but additional fastener strips may be attached and used if a more secure hold is required. Fig. 2 also

shows the three elastic straps 22a-22c that wrap under the mattress (discussed below) to secure the flat

edges of fitted sheet 14 to the mattress 24.

The blanket as seen in Fig.2 may be adapted for smaller infants by folding the sides of the blanket

to reduce the blanket' s overall width. Preferably, the right side of the blanket would be folded toward the

front surface of the blanket and fastened with snap fasteners 13 present thereon. The left side of the

blanket would preferably be folded toward the back surface of the blanket and secured with snap fasteners

15 present thereon. Fig.3 is a bottom view of a safety sheet/blanket 10 wrapped around a mattress 24. This view

shows the two pockets 26a, 26b defined in the fitted sheet 14 which secure the fitted sheet to the foot and

head portions of amattress 24. An elastic band 28 functions to keep the two pockets 26a, 26b securely

wrapped around a mattress. Three elastic straps 22a, 22b, and 22c keep side edges of the fitted sheet

14 secured to the mattress. The sheet 14 may have several cloth reinforced grommets 23 dispersed along

the sides the sheet. These grommets 23 may serve as anchor points for bungee cords or other suitable

holding devices when securing the crib sheet blanket combination to the bed frame of a large bed so that

the crib safety sheet/blanket 10 may be used when a crib is not available, e.g., when traveling.

Fig.4 shows a perspective view of the bottom of safety sheet/blanket 10. The elastic straps 22a-

22c are removably attached to one side of the fitted sheet 14, one strip of hook and loop fastening material

30a-30c for each strap 22a-22c being sewn to the fitted sheet 14 and a mating strip of hook and loop

fastening material 32a-32c (seen in relief) being sewn to the elastic straps 22a-22c.

Fig.5 shows a second embodiment 50 of the safety sheet/blanket that is used for infants who need

additional physical support while sleeping. This embodiment and all following embodiments are similar to

the first embodiment and the same reference numbers represent identical components.

The second embodiment of the safety blanket/sheet combination has a second blanket 40 with a

top and bottom surface that is attached to the first blanket 12. The first blanket 12 is shown larger in this

figure for illustration purposes. One horizontal line of stitching 42 holds together the tops of both blankets

and four vertical lines of stitching 44a-44d hold together the edges and the centers of the blankets. The

four vertical lines of stitching 44a-44d also divide the blankets into three vertical sheaths 46a-46c. The

bottoms of the sheaths 46a-46c may be closed using the snap fasteners 48 located on the bottom surface

of the second blanket 40 and the top surface of the first blanket 12. Hook and loop fastening material,

zippers, and any other fastening devices known to one skilled in the art may be substituted for the snap fasteners. Some of the hook and loop fastening material 16a, 16b has been moved in this embodiment to

the top surface of the second blanket 40 from their position in the first embodiment on the top surface of

the first blanket 12.

The second embodiment of the crib safety sheet blanket combination is used in the same manner

as the first embodiment except that supportive material such as egg-crate cushioning material or air pad-

type material may be inserted into the sheaths 46a, 46b, 46c. Temperature regulating material such as hot

and cold packs may also be inserted into the sheaths 46a, 46b, 46c. The supportive material is secured

inside the sheaths by using the snap fasteners 48 located at the bottom of the sheaths.

The third, fourth and fifth embodiments of the crib safety sheet/blanket will now be described.

These embodiments involve modifications to the fitted sheet. The third through fifth embodiments may

employ either the blanket 12 described in the first embodiment of Figs. 1 -4 or the double blanket 12, 40

design described in the second embodiment of Fig.5. The following description describes modifications

to the sheet and their use with only the first blanket.12 for clarity.

A third embodiment 50 of the present invention, as shown in Fig.6, replaces the fitted sheet of the

first embodiment with a cloth sack 52 or case generally resembling an enlarged pillow case. The sack 52

has a top surface, bottom surface and one open end, the top surface being formed by a sheet as an integral

part of the sack 52. Bedding material such as a basinet pad or a small mattress is ordinarily inserted into

the sack 52 through the open end. The blanket 12 is sewn to the top surface of the sack 52 in the same

manner that the blanket 12 is attached to the fitted sheet 14. In all other respects the blanket 12 is identical

to the first embodiment, and will not be described further.

A fourth embodiment 60 of the present invention is illustrated in Fig.7. This embodiment 60

substitutes a preferably rectangular sheet 62 of material in place of the fitted sheet 14 of the first

embodiment. The sheet 62 has a front surface 64, back surface 66, a top edge, a bottom edge, a left edge 68 and a right edge 70. A fastening device such as hook and look material 72 is disposed upon both the

right 70 and left 68 edges. Snap fasteners or any other suitable fastening devices may also be used in place

of the hook and loop material. The sheet 62 further has plurality of apertures 78 defined between its front

64 and back 66 surfaces. The apertures 78 are preferably located close to, and parallel to, the right 70

and left 68 edges. However, placement of the apertures 78 near the edges 68 and 70 of the sheet is not

a critical aspect of the invention, and the apertures 78 may be more centrally located as discussed below.

As in the third embodiment, the blanket 12 is sewn to the front surface 64 in the same manner as the

blanket 12 is attached to the fitted sheet 14, and is identical in all other respects to the blanket 12 of the

first embodiment, and will not be described further.

The fourth embodiment 60 may be used as illustrated in Fig.8 on a full size adult mattress. The

sheet 62 is placed back surface 66 down on the top surface of a mattress. Adjustable straps 80 are

looped through the apertures 78 and through posts on the bed frame or an accessory guard rail in order

to secure the sheet 62 to the mattress. It is well within the ability of one skilled in the art to design a wide

range of suitable apertures 78 ranging from cloth reinforced slits to metal or plastic reinforced rings. It must

be noted, however, that any apertures containing hard or uncomfortable materials should be located more

centrally on the sheet so as not to become uncomfortable to an infant when the invention is used on crib

pads or bassinets as discussed below.

The fourth embodiment 60 may also be used on smaller bedding materials, such as a crib mattress,

as shown in Figs.9 and 10. For these smaller applications the sheet 62 is wrapped completely around the

mattress approximately midway between the head and foot of the mattress, with the back surface 66 of

the sheet 62 coming into contact with the mattress. The left 68 and right edges 70 of the sheet are secured

to one another using the aforementioned hook and loop material 72. The fourth embodiment may also be used on even smaller bedding material such as a bassinet pad.

First, the left 68 and right 70 edges of the sheet are attached to one another as detailed above, but without

the intervening mattress. The double thickness sheet 62 is then wrapped around a bassinet pad or the like.

The sheet 62 is then secured in position by connecting fasteners 77 to fasteners 79.

A fifth embodiment 80 of the present invention, as illustrated in Figs. 11 and 12, uses the blanket

12 of the first embodiment but substitutes a generally rectangular sheet 82 for the fitted sheet 14 of the

aforementioned embodiment. The sheet 82 has a front surface, back surface, and two opposing ends.

Disposed adjacent to each opposing edge are several sections of hook and loop material 84.

Several straps 88 have one end attached to the sheet 82 and are wrapped around beneath the

mattress or crib frame, having a second end with corresponding sections of hook and loop material 86

which are releasably attachable to the aforementioned hook and loop material 84 on the sheet 82. Hook

and loop material is the preferred method of strap attachment but any suitable method including but not

limited to, buttons, snaps and buckles may also be used. The straps 88 themselves preferably have elastic

properties, but any suitable strap may be used. Each of the straps 88 is attached to or threaded through

a spacer 90. The spacer 90 is a flat, generally rectangular sheet which serves to hold the straps and keep

the straps 88 properly positioned and oriented. In use, the spacer will be disposed beneath the mattress.

The fifth embodiment 80 also has two sets of corresponding fasteners 91, 92. Fasteners 91 are designed

to attach to opposing fasteners 92 and in so doing reduce the overall size of the sheet 82 and thereby

prepare the apparatus for smaller size bedding materials.

It is well within the abilities of one skilled in the art to alter the shape and/or size of the fitted sheet

and blanket to fit a variety of different infant sleeping devices such as cribs, bassinets, incubators and

playpens. The sheet and the blanket may be made from any suitable material, including cotton, wool,

polyester, silk, lycra TM and nylon. It is to be understood that the present invention is not limited to the sole embodiment described

above, but encompasses any and all embodiments within the scope of the following claims.
