TECHNICAL FIELD
This invention relates to a sleep positioner for holding an infant while sleeping.
BACKGROUND
Many parents elect to place their infants on adult beds for napping or sleeping. Research has demonstrated that infants who sleep with their parents (sometimes referred to as “co-sleeping”) breastfeed more and receive more protective care and attention during the night, which can be beneficial to the developing child. When co-sleeping, however, parents must take special precautions to ensure the safety of the child such as to avoid possible entrapment of the infant between the bed and the wall or between the bed and headboard, and to limit the infant's contact with soft bedding materials.
A device is desired that can facilitate the advantages attendant to co-sleeping while reducing any associated risks and enhancing child comfort.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the infant sleep positioner 10 generally includes a shell assembly 15, a base 20, and a foot stop 25. In one embodiment, the shell assembly 15 is a three-sided basin defining an opening and including a left wall 27, a right wall 28, and a back wall 29, each wall extending upwardly in a substantially vertical orientation. The positioner 10 is configured for placement and retention on a bed 30.
In one embodiment, left and right side netting walls 35, 37 extend along the base 20 from the left and right walls 27, 28 of the shell assembly 15 to the foot stop 25. The netting walls 35, 37 can include an elastic cord threaded along the top seam of the mesh to keep the walls 35, 37 taught while permitting some deformation when a load is applied as well as folding the positioner 10 in a stowed state (FIG. 6). The walls 27, 28, 29 of the shell assembly 15, the left and right side netting walls 35, 37 and the foot stop 25 generally define the perimeter of a rectangular sleep space for the placement and protection of an infant 38. In one embodiment, the infant sleep positioner 10 includes a night light 39, including a battery holder, switch, bulb and lens, integrally mounted to a top portion of the back wall 29 of the shell assembly 15.
As shown in FIG. 2, the infant sleep positioner 10 is positioned on the bed 30 and an infant 38 is placed within the sleep space in a supine position within the sleep space of the infant sleep positioner 10.
Referring now to FIGS. 1 and 3, the shell assembly 15 includes a fabric layer 40 covering a basin core 45. Between the fabric layer 40 and the basin core 45, a layer of batting material (not shown) may be provided to impart softness to the infant sleep positioner 10. In one embodiment, the basin core 45 is formed from polypropylene and the fabric covering is polyester or a polyester blend. A portion of the basin core 45 includes a plurality of ridges or standoffs 50 and a plurality of recess regions 53 between the ridges 50. In one embodiment, a plurality of apertures 55 are located within the recess regions 53 to permit airflow through left and right walls 27, 28 of the shell assembly 15. In an embodiment, the mesh side walls 57, 59 (FIG. 1) overlay the ridges 50 to inhibit the infant 38 from contacting the recessed regions 53 between the ridges 50 and affecting normal breathing.
Preferably, as shown in FIG. 3, a top rim 65 steps the mesh side walls 57, 59 away from the standoffs 50 of the left and right shell walls 27, 28 to define a plurality of interstitial spaces 60. If the infant 38 should roll over and position his or her face proximate to the left or right side walls 27, 28, mesh side walls 57, 59 prevent the infant 38 from covering the apertures 55 and the air flow to the infant and the sleep space is not compromised. A removable mattress 70 is provided in one embodiment to fit within the sleep space and provide additional comfort to infant 39 (FIG. 2).
In one embodiment, a positioner insert 75 is removably located within the sleep space to provide additional stability to the infant 38 occupant. The insert 75 includes left and right nacelles 80, 85 each having an extension tab 90, 95 extending horizontally therefrom. The extension tabs 90, 95 are removably attached together to define a desirable distance between the nacelles 80, 85 generally corresponding to the width of the infant. In one embodiment, the nacelle 80, 85 are hollow cylindrical or polygonal elements and include mesh ends 90, 95 at both ends of the nacelles to permit air flow therethrough.
Referring now to the embodiment of FIG. 4, the fabric layer 40 contains a zippered opening 100 in the back of the infant sleep positioner 10 for receiving the basin core 45. An anchoring flap 105 is shown flexibly attached to a lower portion of the rear wall 29. In further embodiments, an anchoring extension 110 is flexibly attached to the anchoring extension 105. In one embodiment, the anchoring flap 105 is removably attached to the rear wall 29 at a tab 115 with hook and loop type fasteners to permit the adjustment of length L to accommodate mattresses 30 of varying heights as will be described below. Either the anchoring flap 105 or the anchoring extension 110 may include a masonite panel for additional rigidity.
Referring now to the embodiment of FIG. 5, the infant sleep positioner 10 is installed atop a mattress 30 with the anchoring flap 105 positioned between the mattress 30 and a wall, headboard or footboard 120 and the anchoring extension 110 is positioned between the mattress 30 and a foundation 125. In one embodiment, the length of the anchoring flap 105 is adjusted by disengaging the hook and loop fasteners holding the flap 105 to the tab 115 and reapplying the anchoring flap 105 to the tab 115 such that the anchoring extension 110 extends to the gap between the mattress 30 and the foundation 125. Tucking the anchoring extension 110 between the mattress 30 and foundation 125 and/or securing the anchoring flap 105 securely between the mattress 30 and the wall, headboard or footboard 120 minimizes lateral movement of the infant sleep positioner 10 when positioned on the bed.
Referring now to FIG. 6, the infant sleep positioner 10 is folded into a stowed state for storage or transport. After removing or moving the positioner insert 75 to the shell assembly 15, the base 20 is rolled over the top of the shell assembly 15 and a folding flap 130 is rolled up for releaseable attachment to the back of the rear wall 29 in the direction of arrow 135. The anchoring flap 105 is folded toward the bottom of the shell assembly 15 for releaseable attachment thereto with hook and loop fasteners, for example. A handle 150 is provided in one embodiment for carrying.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, the shell assembly 15 may be configured in a tapered or frusto-conical shape, such that the left and right walls 27, 28 converge at an upper portion and the need for the rear wall 29 is obviated. Accordingly, other embodiments are within the scope of the following claims.
