1. Technical Field
The present invention relates generally to sling carriers adapted to be worn by an adult to support and carry an infant or other young child. More particularly, the present invention is directed to a sling with improved features that allow the sling wearer to more securely hold the infant in the sling, and that improve the support of the infant's head and neck as well as the infant's body while being carried in the sling.
2. Related Art
Baby slings are well known by parents and other persons involved in child care as being suitable carriers for the transport of children. Indeed, various different types of baby slings are currently available from manufacturers of infant products, such as for example the Jelly Bean™ Cargo Sling from Munchkin. Baby slings offer many advantages over other types of child carriers due to their typical simplicity of use, as well as other features. For example, baby slings typically hold the infant in a nestled position near the body of the adult sling wearer, which is often comforting to the child and allows easy monitoring and observation of the infant on the part of the adult wearer. Baby slings also typically allow for easy interaction between the adult wearing the sling and the infant being carried therein, such as for example to feed, soothe or entertain the infant. However, though currently known and available baby slings achieve their primary objective of carrying an infant, they nonetheless posses certain deficiencies that detract from their overall utility.
One of the deficiencies of prior art baby slings is the lack of any restraint or device to keep the infant securely held within the sling. In particular, slings fabricated from one or more layers of pliable fabric often rely on the infant's own weight to keep the fabric pulled snugly about the infant and restrain the infant therein. Such slings typically do not have any other means to restrain the infant, and thus leave the infant vulnerable to accidental falls, especially if the adult wearer bends or stoops while wearing the sling. Many conventional slings are even sold with accompanying warnings urging the wearer to avoid bending over or stooping while the infant is held in the sling. Even for those slings designed to minimize the likelihood of accident, the lack of any means of restraint may nonetheless be a source of unnecessary worry and anxiety to the sling wearer.
Yet another one of the deficiencies of the prior art baby slings is the insufficiency or lack of support for the body and head of the infant being carrier therein. The prior art baby slings are typically fabricated from one or more layers of pliable fabric that individually or collectively define a pocket or compartment adapted to accommodate the infant. However, the pliability of the fabric used to fabricate the sling provides virtually no support for the body and head of the infant. This lack of support, coupled with the typical attachment of the support strap of the sling to opposing longitudinal ends thereof, thus often results in the infant assuming an uncomfortable contour or curved position within the sling. In particular, as the head of an infant is typically relatively large and heavy compared to the infant's body, the infant may have difficulty in keeping their chin comfortably raised up off of their chest when laid in a supine or semi-supine position in the sling. Not only is this lack of support uncomfortable for the infant, but it also raises concerns with regard to possibly serious obstruction of the infant's breathing passageways. For example, as described in the article entitled “Cardiorespiratory Stability of Premature and Term Infants Carried in Infant Slings” to Stening et al, in Pediatrics Vol. 110, No. 5, November 2002, which is herein incorporated by reference in its entirety, a significant decrease of oxygen saturation was observed in infants carried in a conventional sling as compared to those placed in a pram. While the decrease was not deemed to be of clinical concern, the study nonetheless shows a trend that correlates sling carrying of infants with increased obstruction of breathing.
Accordingly, there remains a need in the art for slings that are capable of securely restraining an infant therein to reduce the likelihood of accidental falls and/or injury to an infant held in the slings. There is also a need for slings adapted for carrying an infant that provide improved support to the infant's head and/or neck region.
The present invention specifically addresses and alleviates the above-identified deficiencies in the art. In this regard, the present invention is directed to an adjustable sling for carrying an infant. In one embodiment, the adjustable sling has a sling body that defines an interior compartment for carrying the infant, and an adjustable shoulder strap extensible about a wearer's shoulder, with first and second opposing ends of the strap being attached to the sling body. The sling also has an adjustable lumbar belt that attaches to the sling body and is extensible about the wearer. To enhance the security and safety of an infant being held in the interior compartment, the sling has a retention flap that is attached to the sling body and that is capable of securing and retaining the infant being carried in the compartment.
In yet another embodiment, the adjustable sling has a sling body that defines an interior compartment for carrying the infant and has at least one support insert therein. The support insert is configured to support at least one of the infant's head and neck while the infant is being carried in the interior compartment of the sling. The adjustable sling may also include an adjustable shoulder strap extensible about a wearer's shoulder, with first and second opposing ends of the strap being attached to the sling body. Further, the adjustable sling may include an adjustable lumbar belt that attaches to the sling body and is extensible about the wearer.
The present invention is best understood by reference to the following detailed description when read in conjunction with the accompanying drawings.
These as well as other features of the present invention will become more apparent upon reference to the drawings wherein:
Common reference numerals are used throughout the drawings and detailed description to indicate like elements.
The detailed description set forth below is intended as a description of the presently preferred embodiment of the invention, and is not intended to represent the only form in which the present invention may be constructed or utilized. The description sets forth the functions and sequences of steps for constructing and operating the invention. It is to be understood, however, that the same or equivalent functions and sequences may be accomplished by different embodiments and that they are also intended to be encompassed within the scope of the invention.
An adjustable sling 10 for carrying an infant 12 has been developed that provides substantial improvements over prior slings by providing secure restraint of the infant 12 being held therein, as well as improved support of the infant's head and neck regions. In one embodiment, the adjustable sling 10 comprises a specially devised retention flap 14 that comfortably and securely retains the infant 12 within the sling 10. In another embodiment, the adjustable sling 10 comprises a unique head and/or neck support insert 16 that provides improved comfort to the infant 12 being held in the sling 10. An improved adjustable sling 10 according to the invention may have either of these improved features individually, and may also comprise a combination of the features to improve the safety and comfort of the sling 10 in the transport and carrying of an infant 12.
It should be understood that the term “infant” as referred to herein is intended to be inclusive of all children and babies that may be suitably carried by the sling, and thus includes very young infants as well as older babies and children. In particular, the sling may be suitable for carrying very young infants and children that are 35 lbs or less, and especially those that are 20 lbs or less. Also, while it is envisioned that a likely wearer of the adjustable sling would be the child's parent, the wearer may also be another adult or teenager of a suitable age involved in the care of the child, such as a day care provider, sibling, grandparent and the like.
The sling body 18 can comprise a variety of different sizes, shapes and configurations adapted to provide an interior compartment 20 suitable for holding an infant 12 therein. In the version depicted in
Referring again to
In the embodiment shown in
In one version, at least a portion of the retention belt 40 is attached to the retention flap 14 itself to position and stabilize the belt 40, for example by sewing or otherwise attaching a portion of the retention belt 40 thereto. For example, the retention belt 40 can comprise first and second belt strap segments 44a, 44b, with a first belt strap segment 44a extending from a first opposing edge 48a of the elongate bottom panel 28 towards the retention flap 14, and the second belt strap segment 44b extending from a second opposing edge 48a of the elongate bottom panel 28 towards the retention flap 14, as shown for example in
While specific embodiments of the retention belt 40 and retention flap 14 are being described herein for the purposes of illustrating aspects of the invention, it should be understood that the retention flap 14 and belt 14 are not limited to these specific embodiment, and other configurations may also be devised. For example, the retention flap 14 may itself form a central section of the belt 40, with first and second belt strap segments 44a, 44b being attached at opposing sides thereof and extending to connect to the sling body 18. Also, the retention belt segments 44a, 44b and/or retention flap 14 may be connected to each other via connectors other than those specifically shown, such as for example via snaps, zippers, hook and loop closures such as Velcro™, and/or buttons. Embodiments in which the retention flap 14 is directly attached to the sling body 18 without the use of a retention belt 40, are also considered to be encompassed by the present invention. For example, in one embodiment, the retention flap 14 can comprise attachment mechanisms disposed at opposing lateral ends of the transverse band segment 34 that are capable of attaching the ends of the retention flap 14 to the sling body 18.
Accordingly, in one version, a method of employing the sling 10 for use in carrying and/or transporting an infant 12 involves laying the infant 12 on his/her back within the interior compartment 20 of the sling 10. The infant is placed in a supine or semi-supine position on the elongate bottom panel 28, with the infant's bottom positioned above the point of attachment of the retention flap 14 at the proximal end 36a of the elongate lower segment 32. The retention flap 14 is folded back over the infant's body, with the elongate lower segment 32 passing between the infant's legs and the transverse band segment 34 of the retention flap 14 crossing over the body of the infant 12, such as across the infant's stomach and/or torso. At least a portion of the retention belt 40 is extended through the sleeve 38 of the transverse band segment 34, and the belt 40 is secured via at least one releasable mating connector 50. The retention flap 14 can thus be used to gently and securely retain the infant in the interior compartment 20 of the sling body 18, thereby reducing the likelihood of accident or injury to the infant 12 while using the sling 10.
FIGS. 2 and 5-7 show yet another embodiment of the adjustable sling 10, wherein the sling 10 is configured to provide improved support to at least one of the infant's head 13 and neck 11 while the infant 12 is carried therein, as well as optionally to other portions of the infant's body. In this embodiment, the sling body 18 comprises at least one, and even a plurality of support inserts 16 that are shaped, sized and configured to improve the support of the infant. The improved support imparted by the support inserts 16 enhances the infant's comfort while being carried in the sling, and may also advantageously improve the positioning and alignment of the infant's breathing passages to ensure adequate oxygen saturation and breathing ability of the infant 12.
In one version, the support insert 16 comprises a neck support bolster 15 that is configured to maintain a position of the infant's neck 11 in relation to the head 13 of the infant 12, as shown for example in FIGS. 2 and 5-6. Specifically, the neck support bolster 15 is configured to maintain the infant's head 13 in a substantially neutral and/or mid-line position relative to the infant's spine when the infant 12 is in one or more of a supine or semi-supine position. By “neutral” or “mid-line” position it is meant that the infant's head 13 is positioned relative to the spine such that the head 13 is not bending excessively towards or away the spine, such as excessively forward, backward, or even sideways with respect to the spine, in a position that could otherwise be unacceptably uncomfortable to the infant 12 or restrict the infant's breathing. By maintaining the head and/or neck in such a neutral position, the infant's breathing passageways are kept unobstructed such that the infant 12 is able to breathe easier and maintain higher oxygen levels. In particular, the neck support bolster 15 is configured to lift a portion of the infant's neck 11 and/or body 17 with respect to the infant's head 13 such that the infant's chin is kept from excessively bending towards and even into the infant's chest, thereby maintaining proper air passageway alignment. The neck support bolster 15 may preferably be formed of a cushioning foam material, although other padding or cushioning materials can also be used.
In the version shown in FIGS. 2 and 5-6, the neck support bolster 15 is anatomically shaped and positioned within the sling body 18 to allow the infant's scapulae, or shoulder blades, to rest thereon, thereby lifting the infant's upper back and neck regions to maintain the infant's head 13 and neck 11 in proper alignment. In this version, the elongate bottom panel 28 can be understood to comprise a head support region 54a configured to support the infant's head 13, and a body support region 54b to support the infant's body 17, with the neck support bolster 15 being disposed adjacent the head support region 54a at a location along the longitudinal axis of the elongate bottom panel 28 that allows for the lifting and support of the infant's upper back/shoulders and/or neck, such as between the head support region 54a and body support region 54b. The neck support bolster 15 further comprises a top surface 19 that is elevated above a surface 21 upon which the infant's head 13 rests in the head support region 54a of the elongate bottom panel 27, thereby lifting the infant's upper back and/or neck with respect to the infant's head 13. For example, the top surface 19 of the neck support bolster 15 can be at least about 0.5 inches higher than the head rest surface 21, such as from about 0.5 to about 1.0 inches higher, and even about 0.75 inches higher than the head rest surface 21. In the embodiment as shown in
The adjustable sling 10 can further comprise additional support inserts 16 disposed within the interior compartment 20 of the sling body 18 that are configured to support and cushion the infant's head 13 and/or neck 11 as well as to support and properly position the rest of the infant's body 17. In one embodiment, an additional support insert 16 comprises a head support insert 25 disposed towards an upper end 64a of the sling body 18 that at least partially conforms to a periphery of the infant's head 13 to maintain a position thereof. The head support insert 25 thus serves to promote proper alignment of the infant's head 13 with the rest of the infant's body 17, such as a substantially neutral alignment of the infant's head and spine, by inhibiting excessive lateral bending or twisting of the infant's neck 11. In the version shown in FIGS. 2 and 5-6, the head support insert 25 comprises a generally U-shaped body of cushioning material positioned at the upper end 64a of the elongate bottom panel 28, such as for example lining at least a portion of the side panels 30a, 30b at the upper end 64a of the sling body 18. The head support insert 25 thus forms supporting walls about the infant's head 13, with the interior surface 29 of the head support insert 25 being contoured to at least partially conform to the infant's head 13 while also allowing the infant a comfortable amount of head movement within the sling body 18. The head support insert 25 may preferably be formed of a cushioning foam material, although other padding or cushioning materials can also be used.
In yet another version, the additional support inserts 16 provided in the infant sling 10 comprise one or more body support bolsters 33a, 33b that are configured to support and position opposing sides of the infant's body 17. In the embodiment shown in FIGS. 2 and 5-6, the body support bolsters 33a, 33b comprise arcuate bodies of cushioning material disposed on opposing sides of the elongate bottom panel 28 in the body support region 54b. The body support bolsters 33a, 33b thus inhibit excessive lateral slipping of the infant 12 within the interior compartment 20 of the sling body 18, and also promote a proper and comfortable alignment of the infant's body 17 therein. The body support bolsters 33a, 33b also cooperate with the retention flap 14 to properly position the infant 12 within the sling body 18 for optimum comfort and support. Similarly to the head support insert 25, the body support bolsters 33a, 33b may be formed of a cushioning foam material, or alternatively of another padding or cushioning material.
In yet another embodiment of a support insert 16 as shown in
To further increase the comfort and support of an infant 12 being carried and/or transported in the adjustable sling 10, the sling 10 may further comprise at least one cushioning insert 60 extending along at least a portion of the sling body 18, as shown for example in
In one version, the support and/or cushioning inserts 16, 60 are inserted into the sling body 18 by sewing or otherwise permanently attaching to the sling body 18. However, it should be understood that the inserts 16, 60 can also be provided in a detachable form such that the inserts 16, 60 can be placed in the sling body 18 and then removed as desired. For example, one or more of the support and cushioning inserts 16, 60 can comprise snaps, button, zippers, hook and loop-type closures, or other types of closures that releasably attach the inserts 16, 60 to the support body 18. In a preferred embodiment, at least one and even both of the head support insert 25 and body support bolsters 33a, 33b are configured to be readily detachable from the sling body 18, for example to accommodate a larger or older infant 12. The neck support bolster 15 may also optionally be provided in detachable form.
The construction of the sling body 18 is devised to provide support and comfort to the infant 12, as well as the sling wearer 24. In the version shown in
The sling body 18 is supported on the wearer 44 via at least one adjustable shoulder strap 22 that is extensible about the wearer's shoulder and/or back, as described above. As shown in
Further support for the sling body 18 during use in transporting and/or carrying an infant 12 can be provided by the adjustable lumbar belt 26 as described above, which is configured to attach to the sling body 18 as well as extend about the body of the wearer 24. For example, as shown in
The belt loops 70a, 70b located on opposing sides of the sling body 18 allow for the wearer 24 to selectively position the sling body 18. For example, in the version as shown in
The adjustable sling 10 can further comprise other attachments and/or modifications that are generally suitable for child carriers, and/or that otherwise enhance the performance of the sling 10. For example, the sling 10 can comprise one or more interior or exterior pockets or pouches configured to hold infant care items, such as bottles, toys, blankets, pacifiers, diaper changing supplies, and the like, and optionally other accessories such as cell phones, wallets, keys, and other similar items. The sling 10 may also comprise further straps and attachment members and devices to adjust the shape and configuration of the sling body 18. For example, in one version, the periphery 82 of the side panels 30a, 30b can be elasticized to at least partially enclose the sling body 18 about the infant 12. Additionally or alternatively, the periphery 82 of the side panels 30a, 30b can comprise a cinching strap or similar mechanism (not shown) to adjust the size thereof, and thus adjust the size of the opening to the interior compartment 20.
The improved sling 10 according to the present invention can thus be understood to provide improved comfort and security to an infant 12 being carried and/or transported therein. The retention flap 14 allows for an infant 12 to be more securely retained and held within the interior compartment 20 of the sling 10, thus reducing the likelihood of accident or injury to the infant 12. The support insert 16 increase the infant's comfort by stabilizing the head and/or neck of the infant 12. The improved sling 10 thus provides for more secure, comfortable and stable transport of an infant 12, substantially without sacrificing desirable aspects of conventional infant slings.
Additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art. Thus, the particular combination of components and steps described and illustrated herein is intended to represent only certain embodiments of the present invention, and is not intended to serve as limitations of alternative devices and methods within the spirit and scope of the invention. Along these lines, it should be understood that the retention flap 14 and support insert 16 may take any of a variety of forms that are known or later developed in the art, and further contemplates that existing or newly formed retention flaps 14 and support inserts 16 should fall within the scope of the present invention. Also, it should be understood that the shoulder strap 22, lumbar belt 26 and carrier body can comprise other configurations that are other than those specifically described.
