Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to safety sleeping bags for infants and
babies provided with means for securing the bag to the mattress of
the crib whereby the baby can move in a relatively free manner, yet
is prevented from standing up in the crib or kicking the clothes
off.
2. Description of the Prior Art
Such a safety sleeping bag is disclosed in German Utility Model
Patent 7132 774. In this safety bag, a portion of the sleeping bag
is enlarged and attached to the mattress by pulling it around the
latter. While this permits the infant to have some freedom of
movement, it is desirable that the infant be able to move even more
freely and unrestrainedly.
SUMMARY OF THE INVENTION
This invention aims at producing an improved safety sleeping bag by
attaching a sleeping blanket, in the area of the back, to a
bedlinen sheet which can be stretched and fittedly attached to the
crib mattress in a well known manner. The special advantage of this
invention is the infant is permitted the maximum of movement
possible while still prevented from standing up in the crib. With
all this, the safety sleeping bag of this invention can be rapidly
and easily attached and detached from the crib mattress.
The back area of the sleeping bag can be attached to the bedlinen
sheet in several ways. Perferably, a surface portion of the back
area is sewn to the sheet. In a further development, the surface
portion is sewn to the stretchable sheet together with a soft
absorbant filler such as that known under the mark MOLTON. This
filler prevents the wetting of the mattress and covers the possibly
harder seam area. In this structure, the surface portion which is
sewn on is shaped as an ellipse whose longitudinal axis extends in
the head-to-foot direction. In this embodiment, when the infant
tries to rise, a force is transmitted from the child to the
sleeping bag and from the back area thereof, which is sewn on, to
the stretchable sheet, which is pulled around the mattress.
To improve the attachment in preferred embodiments of the invention
and particularly in the caSe of children already able to stand or
walk, there is attached, preferably by sewing on to the stretchable
sheet on the side facing away from the safety sleeping bag, a
tension band which surrounds the crib mattress. Such a tension band
absorbs even rather strong forces without undesirable permanent
extensions. Further, such a tension band eliminates the need for
possibly dangerous strips or straps on the upper surface of the
sleeping bag.
The bedlinen sheet can be of various shapes. For example, it can be
shaped as a bag in which the mattress is inserted in a longitudinal
direction. In a preferred embodiment of the invention, a
stretchable sheet is sewn in the shape of an open case with flaps
adjacent to the edges. The periphery of the flaps is provided with
a preferably elastic rubber ribbon. To attach the safety sleeping
blanket to the mattress, the stretchable sheet is placed on a
support with a sleeping bag below. The mattress is placed on top of
the sheet and the flaps adjacent to the edges are then pulled
upward over the edge of the mattress. The four flaps are tightened
together by means of the elastic ribbon. If a tension band is
provided, the ends of the tension band are joined by an appropriate
closure.
In a further development of this invention, the sleeping bag is
provided with a bodice-like upper portion having an open square
neck of the same dimensions in the front and in the rear. This
embodiment presents the advantage that the child can lie with equal
comfort on his back or on his stomach.
It is known to provide sleeping bags with a zipper so that the
child can be conveniently put into and taken out of the sleeping
bag. Such zippers are all indivisible and their slides in the
closed position are located near the neck opening of the sleeping
bag. This results in the disadvantage that the child can play with
the slide and possibly suffer some injury and can open the sleeping
bag and crawl out of it, so that the bag no longer complies with
the necessary requirements for constraining the child.
In a preferred embodiment of the invention, a longitudinally
extending divisible zipper is provided whose slide at the closed
position is in the area of the child's feet. Thus, the child cannot
reach the slide and neither get pinched nor open the sleeping bag.
The use of the safety sleeping bag is in no way restrained since by
the employment of a known divisible zipper the two zipper halves
can be separated when the slide is fully pulled upward to the neck
opening.
The employment of a divisible zipper in an arrangement where the
slide is located at the closed position in the base area is not
limited to the use in safety sleeping bags, which in the back are
attached to a linen sheet, but rather such an arrangement can be
used in all sleeping bags which are not to be readily opened by the
person in the sleeping bag.
A further improvement of the safety sleeping bag is achieved by
attaching a retainer for disposable diapers below the ellipse
shaped surface portion. After the child has been placed with his
buttocks on the disposable diaper, flaps can be folded upward
around the child's legs and secured to the back portion of the
sleeping bag. The flaps retain the disposable diaper in position
relative to the child and prevent the child from sliding down in
the sleeping bag even in the case of vigorous kicking movements.
The retaining means also can be used with a conventional diaper or
no diaper at all.
The safety sleeping bag of the invention as well as the stretchable
bedlinen sheet may be made of a diversity of materials. Preferably,
the sleeping bag is made of a stretchable terrycloth and the edges
of the bag, as well as the top of the sheet, are covered with the
same material. The employment of this material is advantageous
because it is absorbant and soft. The stretchable bag has the
further advantage that the number of sizes to be manufactured and
to be kept on hand can be kept relatively low .
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an elevated perspective view of a safety sleeping bag
attached to a mattress.
FIG. 2 is a perspective view of the safety sleeping bag of FIG. 1
from the opposite side of the mattress.
FIG. 3 is a perspective detail of a retainer for a disposable
diaper within the safety sleeping bag of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A stretchable bedlinen sheet 2 is placed on a mattress 1 and can be
pulled around the edges of the mattress to secure the sheet. The
sheet 2 is sewn in the shape of an open case whose bottom abuts the
upper surface of mattress 1 as shown in FIG. 2. Flaps 4, attached
to the edges 3, are located in the plane of the lower surface of
the mattress 1.
The edge of these flaps is covered with a strechable terrycloth
material and a ribbon is inserted therein which consists preferably
of an elastic rubber material.
A sleeping blanket 5 has a lower region which is bag-like and an
upper region which is bodice-like. The back area of the sleeping
blanket 5 is sewn with an ellipseshaped surface portion 6 to the
stretchable bedlinen sheet 2. A tension band 7 is sewn on the side
of the sheet which faces mattress 1 and passes between mattress 1
and sheet 2 around the mattress and is tied or otherwise secured in
the area of the free ends 8. The infant sleeping bag 5 is thereby
detachably connected with mattress 1. Nevertheless, the greatest
freedom of movement for the child is secured since only the area of
surface portion 6 is attached to the bedlinen sheet. No banded
structure, or the like, whatsoever is provided on the top side of
the sheet.
The bodice-like upper portion is provided with an armhole 9 on each
side while a square neck 10 is provided with equal dimensions in
the front portion as well as the back portion. A zipper 11 is
affixed to the front portion of the bag and extends from the square
neck to the base area of the bag. Zipper 11 is a divisible type
whose divisible end is located in the region of square neck 10. The
slide 12 of the zipper 11 is in a closed position in the base area
of sleeping bag 5 and can therefore not be reached by the baby or
infant. The edges of armholes 9 as well as of square neck 10 are
covered with stretchable terrycloth material.
According to FIG. 3, a retainer for a disposable diaper 15 is
attached to the back portion of the sleeping bag below the
ellipse-shaped surface portion 6. The attachment can be carried out
by means of buttons 16 or may be sewn in place to the back portion
of sleeping bag 5.
After the child has been placed with his buttocks on a disposable
diaper appropriately positioned, and the legs of the child placed
in the direction of the two arrows 17, the two flaps 18 are folded
upward over and around the legs of the child and fastened to
buttons 16 by means of buttonholes 19. The two flaps 18 prevent the
child from sliding down even in the case of vigorous kicking
movements without otherwise practically restricting his freedom of
movement. Since the child is prevented from sliding down in the
bag, unnecessary chafing of the child's neck at the square neck of
the sleeping bag is prevented. A disposable diaper is readily
replaceable within the retainer 15 and if necessary to improve the
hygienic conditions, a waterproof support may be buttoned on
beneath the disposable diaper.
Some of the characteristics of the invention can be employed
separately, or in combination. For example, a divisible zipper
arranged in a manner described can also be employed in other
sleeping bags for children or kicking bags and the like. Likewise,
a great variety of modes of attaching the bedlinen sheet to the
mattress is possible, such as shaping the sheet as a bag for the
insertion of the mattress therein.
