With reference to an example embodiment shown in FIGS. 1-3, a lounger 10 generally comprises a central support portion 12 bounded by first and second sidewalls 14, 16 along opposite lateral sides of the central support portion 12. The central support portion 12 is generally concave and defines a length and a width sufficient to comfortably support a child or infant thereon. The central support portion 12 comprises an upper portion for supporting the child's head and back, a lower portion for supporting the child's legs, and a seat portion between the upper and lower portions for supporting the child's seat. The upper and lower portions of the central support portion 12 are preferably oriented at an obtuse angle relative to one another, for example about 100°-170°, and more preferably about 120°-160°. The seat portion preferably comprises a smoothly radiused transition between the upper and lower portions, or alternatively can comprise an angled transition. In an example embodiment, the width of the central support portion 12 is greater at the ends of the upper and lower portions, and narrower in the seat portion, defining an hourglass-shaped profile. For example, the central support portion 12 may have a width of about 6′′-8′′ at the seat portion, progressively widening to about 9′′-12′′ at the ends of the upper and lower portions. In an example embodiment, the lounger has an end-to-end length of about 24′′-36′′, for example about 30′′; and an overall side-to-side width of about 16′′-18′′, for example about 17′′. In its normal equilibrium or resting state, the upper portion or head end of the central support portion 12 is elevated above the lower portion or foot end. For example, the head end may be positioned at an elevation of about 10′′-12′′ above the support surface upon which the lounger is placed, and the foot end at an elevation of about 6′′-8′′.
The sidewall portions 14, 16 extend generally upright or at a slight outward inclination from the central support portion 12, along substantially all or at least a central portion of the length thereof, to prevent a child seated or reclining in the lounger from accidentally rolling off the central support portion. The central support portion is generally concave, with the seat portion recessed inwardly, resulting in a greater height of the sidewall portions 14, 16 in the area of the seat portion, and a lesser height of the sidewall portions toward the ends of the upper and lower portions. In an example embodiment, the height of the sidewall portions is about 6′′-8′′ above the seat portion, tapering to about 1′′-2′′ toward the ends. The outer side faces of the sidewall portions 14, 16 are generally parallel to one another, and when the lounger 10 is supported on a floor, table or other support surface for normal use the outer side faces of the sidewall portions are positioned generally vertically, perpendicular to the support surface; and the side-to-side span of the central support portion 12 is positioned generally horizontally, parallel to the support surface.
The lounger 10 optionally further comprises a harness or strap system to secure a child in a seated or reclining position within the lounger. As depicted, a pair of waist belt straps 18a, 18b are releasably engagable with a central coupling panel 20 having cooperating coupling elements or belts 22a, 22b, and a crotch strap 24 extending therefrom, to form a three-point harness system. Alternatively, a single, two-sided buckle can be attached to the crotch strap for engagement with corresponding coupling elements on the waist belt straps 18a, 18b. Buckles, snaps, clips, hook-and-loop fasteners or other releasable coupling means can be provided for attaching the straps to secure the child. In alternate embodiments, differing strap configurations may be utilized, for example a simple two-point waist belt, a five-point harness including shoulder straps, or various other configurations.
The lounger 10 optionally also includes a pocket 30, for example, proximal the head end of the upper portion of the central support portion 12, for containing a sound transmitter 32, vibration transducer, portable music player or other accessory. In the example embodiment of FIGS. 1-3, the lounger 10 comprises a removable fabric slipcover 50 having a zipper 55 or other closure or attachment means, covering a compressible foam core or inner body 60. The foam core 60 can, for example, comprise an integral unitary molding of polyurethane foam; or can comprise separate sections of differing materials, for example a softer more compressible central support portion and firmer or denser sidewall portions
The lower surface of the lounger 10, seen with reference to FIG. 3, defines an outwardly curved surface, allowing the lounger 10 to rock. In the depicted embodiment, the lower surface of the lounger 10 is curved from end to end in the lengthwise or longitudinal direction of the lounger, allowing for forward and backward rocking; and is flat in the transverse or side to side direction. Alternatively, the lower surface of the lounger 10 can be curved along the transverse direction for side to side rocking, or can be convex for both lengthwise and transverse rocking. Optionally, a generally flat section is provided at one or both ends of the curved lower surface to define the forward and backward limits of the rocking motion of the lounger 10. In example embodiments, the ends of the rocking surface are elevated about 1′′-3′′ above the medial portion of the rocking surface that contacts the underlying support surface in the equilibrium state of the lounger, for example about 2′′, such that each end is displaced upwardly and downwardly from its equilibrium position over a vertical span of up to about 2′′-6′′, for example up to about 4′′, upon rocking. In alternate embodiments, the lower surface of the lounger can comprise various different non-flat or non-planar profiles that may or may not enable rocking, for example, an undulating surface with two or more contact points for supporting the lounger on a floor, table or other support surface, and at least a portion of the undulating surface not contacting the support surface. For example in a non-rocking embodiment, at least two contact points of the lower surface of the lounger contact an underlying flat support surface, and at least one non-contact portion of the lower surface of the lounger positioned between the contact points is above and not in contact with the support surface. In a rocking embodiment, at least one contact point of the rocker surface contacts the support surface as the lounger rocks, while other points of the rocker surface are elevated above and not in contact with the support surface.
FIGS. 4-6 show a sequence of fabrication of a foam core of a lounger 110 according to another example embodiment. The foam core generally comprises a central support portion 120 and first and second sidewall portions 160, 170. The central support portion 120 comprises an upper portion 122 and a lower portion 124, and first and second sides 130, 140. A pair of waist-belt slots 126a, 126b and a crotch strap slot 128 are formed through the foam core adjacent the seat portion between the upper and lower portions 122, 124. The upper surface of the central support portion 120 defines a smoothly curved, inwardly recessed profile, and the sidewall portions 160, 170 have complementary outwardly curved profiles along their lower surfaces 162, 172, as seen best in FIG. 5. In this manner, the sidewall portions 160, 170 are assembled into engagement with the upper surface of the central support portion 120, in alignment with sides 130, 140, and attached by adhesive, solvent or thermal bonding, or other attachment means. Optionally, a reinforcement layer such as a non-woven polypropylene reinforcement panel is laminated or otherwise attached in the area of the slots 126, 128 to resist the straps pulling through or detaching from the foam core. Optionally, one or more stiffeners or braces are incorporated in or on the foam core for structural support.
The lower surface of the foam core of the lounger 110 defines an outwardly curved, non-planar central portion 150 between a lower or foot end portion 152 and an upper or head end portion 154. The arcuate curvature of the central portion 150 allows the lounger to rock or pivot about a transverse or side-to-side axis T, in a lengthwise direction L, as indicated by the arcuate rocking motion R. One or more base frame members are optionally provided at the forward and/or rear ends of the rocking surface to limit the magnitude of rocking motion of the lounger. The foam core of the lounger 110 is optionally covered by a fabric cover, or provided with a coating, laminate or other surface treatment for comfort, stain resistance, and/or application of decorative graphics, user information or branding indicia.
