The second child support unit 170 includes a subframe 172 with one or more subframe components comprising a generally rectangular periphery and soft-goods 174, such as fabric and padding, installed onto the subframe 172 to form a sling, bassinet, bed or cradle for supporting a child placed in or on the second child support unit 170, for example to support and contain the child when sleeping or resting. In example embodiments, the subframe 172 comprises two side components, forming the length of the subframe, and coupled to end components, forming the width of the subframe. In example embodiments, the first child support unit 150 is supported through engagement with one or more side cross-members 110 and/or an end cross-member 112 of the frame 102, and the second child support unit 170 is supported through engagement with one or more upright corner posts 104 of the frame 102. Alternatively, the first child support unit 150 can be supported through engagement with one or more of the upright corner posts 104, and the second child support unit 170 can be supported through engagement with one or more side cross-members 110 and/or end cross-member 112. In yet another embodiment, both the first and second child support units 150, 170 can be supported through engagement with one or more of the upright corner post 104, and in still another embodiment, both the first and second child support units can be supported through engagement with one or more side cross-members 110 and/or an end cross-member 112.

The first child support unit 150 is removably attached to the frame by one or more couplings 156. In the example embodiment, the couplings 156 are support struts with engagement clips or collars for releasable engagement with support tubes or other portions of the support frame 102 of the child containment device. In example embodiments, the first child support unit 150 is configured such that its length is parallel with the end cross-members 112 of the frame 102. In example embodiments, the first end of the each support strut 156 is attached to a component of the sub-frame 152, such as a side or end sub-frame component, and the free end of the support strut contains an engagement clip. The engagement clip end of the coupling 156 is snapped onto the child containment device frame 102. In the depicted embodiment, two couplings 156 are attached to a side components of the sub-frame 152 and engage with an end cross-member 112 of the frame 102, and one coupling 156 is attached to each end of the subframe 152 and engages with the respective side cross-member 110 of the frame 102. In alternate embodiments, various alternative coupling elements may be utilized for permanently or detachably mounting the first child support unit 150 to the frame 102. For example, the couplings 156 can comprise engagement clips at both ends of the support struts and can be detachably coupled with both the child containment device frame 102 and the first child support unit subframe 152. Other embodiments comprise alternative arrangements of couplings 156.

The system 100 optionally further comprises a second child support unit 170. In the depicted embodiment, the second child support unit 170 is mounted to the frame 102 with two sleeve mounts 130 and L-shaped mounting bars 160, as shown in FIG. 1. The second child support unit 170 is configured such that its length is parallel with the end cross-members 112 of the frame 102. The first end of each mounting bar 160 attaches to the second child support unit subframe 172 with a ferrule coupling. The second end of the mounting bars 160 attach to the sleeve mounts 130 on the upright corner posts 104 of the frame 102. The sleeve mounts 130 are located on the upright corner posts 104 on the opposite side of the frame 102 from the end cross-member 112 supporting the first child support unit 150. The sleeve mounts 130 comprise a cylindrical channel or receiver that is open at the top, closed at the bottom and has a diameter that will accommodate the mounting bar 160. The second end of each mounting bar 160 is coupled with a sleeve mount 130 by inserting the end of the bar 160 into the open top of the sleeve mount 130. In alternative embodiments, the sleeve mount 130 includes a releasable engagement feature designed to keep the mounting bar 160 engaged with the sleeve mount 130 until the engagement feature is released. Optionally, the mounting bars 160 are rotationally engaged with the sleeve mount 130 to facilitate compact storage when removed from the frame 102. In alternative embodiments, the mounting bar 160 is releasably attached to the subframe 172, for example with engagement clips.

FIGS. 3 and 4 show a child support system 200 according to another example embodiment of the invention. In this embodiment the first child support unit 250 is supported through engagement with one or more side cross-members 210 and/or an end cross-member 212 of the frame 202. The second child support unit 270 is supported on one side by a pivotal coupling with the first child support unit 250 and on the other side by a support member 276 which extends downwardly to engage the raised bassinet mattress 240. In this embodiment, the first child support unit 250 and second child support unit 270 are engaged with a pivotal coupling 262 which allows the second child support unit 270 to be moved between an in-use position (FIG. 3) and a storage position (FIG. 4).

As depicted in FIG. 3, the first child support unit 250 is removably engaged with the side cross-members 210 of the frame 202 through couplings 256 attached to the end components of the first child support unit subframe 252. The first child support unit 250 is configured such that its length is parallel with the end cross-members 212 of the frame 202. The couplings 256 at the ends of the subframe 252 releasably engage with the respective side cross-members 210 of the child containment device frame 202. Alternate embodiments comprise alternative arrangements of couplings.

The second child support unit 270 is coupled to the first child support unit 250 with a pivotal support coupling 262. The second child support unit 270 is configured such that its length is parallel to the length of the first child support unit 250. The second child support unit 270 is positioned adjacent to the first child support unit 250. The pivotal coupling 262 is attached to the first child support unit subframe 252 and the second child support unit subframe 272. The pivotal coupling 262 has a range of motion such that the second child support unit 270 can be rotated from its in-use position, depicted in FIG. 3, to its storage position, depicted in FIG. 4. When in-use, the second child support unit 270 is positioned next to the first child support unit 250 and is horizontal, with the subframe 272 parallel with the child containment device floor 224 and the opening of the second child support unit 270 facing upwards. In the storage position, the second child support unit 270 is also in a horizontal position with the subframe 272 parallel with the child containment device floor 224, but with the opening facing downward. In the depicted embodiment, the second child support unit 270 in the storage position is positioned directly above and resting on the first child support unit 250, moving the second child support unit out of the way to permit access to and from the main containment area of the play yard. In alternative embodiments, the second child support unit 270 is pivoted below the first child support unit 250 in the storage position. In other embodiments, the pivotal coupling 262 includes a lock or catch to prevent the second child support unit 270 from pivoting beyond the in-use position or storage position. Optionally, the pivotal coupling 262 includes a releasable locking mechanism that holds the second child support unit 270 in the in-use or storage position until the releasable lock is disengaged. Further, the sling portion 274 of the second child support unit 270 can be folded when the second child support unit 270 is in the storage position, giving it a substantially flat profile.

Example embodiments also include a support member 276, one end of which attaches to a side subframe component of the second child support unit 270, and the other end of which engages with the bassinet mattress 240 to support the second child support unit 270 in its use position, as depicted in FIG. 3. In the depicted embodiment, the support member 276 comprises a single support leg. The support member 276 is hingedly attached to the second child support unit subframe 272 on the opposite side from the pivotal coupling 262. When in use, the support leg 276 is in a generally vertical position so that it engages with the bassinet mattress 240 and supports the second child support unit 270 in the in-use position. As depicted in FIG. 4, the attachment of the support leg 276 to the sub-frame 272 is hinged or pivotal so that the support leg 276 can be folded into a horizontal or flat position when the second child support unit 270 is pivoted to the storage position.

FIGS. 5-7 show a child support system 300 for a play yard or other child containment apparatus, according to another example embodiment of the invention. In this embodiment, the first child support unit 350 is supported through engagement with one or more channel mounts 330 on the upright corner posts 304 of a play yard frame 302. The second child support unit 370 is supported through engagement with the first child support unit 350 and a support member 376 which engages with the raised bassinet mattress 340 or other portion of the play yard. The first support unit 350, for example, comprises a generally rectangular support sub-frame 352 having first and second side support sub-frame components and first and second end support sub-frame components. A fabric or soft-goods covering is attached to the support frame of the first child support unit 350, for example to provide a changing table or other support surface for positioning an infant or small child upon. The second child support unit 370 also comprises a generally rectangular support sub-frame 372 having first and second side support sub-frame components and first and second end support sub-frame components. A fabric or soft-goods covering is attached to the support frame of the second child support unit 370, for example in the form of a sling or hammock, or a four-sided bed receiver to provide a bassinet, sleeper unit or other smaller containment or resting space for an infant or small child.

As depicted in FIG. 5, the first and second child support units 350, 370 attach with one another in a first or deployed configuration, wherein the first and second child support units are connected and alongside one another over the contained space of the play yard. When attached and in the deployed configuration, the first and second child support units 350, 370 are coupled to one another along their confronting or inboard sides, and are separately supported by the play yard at their opposite or outboard sides. For example, in the depicted embodiment, the first child support unit 350 is supported at its outboard side on corner posts of the play yard frame, and the second child support unit 370 is supported at its outboard side by the upper bassinet mattress or panel 340 of the play yard. In example embodiments, the first child support unit 350 is generally self-supporting (i.e., does not require support from the second child support unit) when mounted to the play yard, whereas the second child support unit 370 is supported on one side by its attachment to the first child support unit. In this manner, the first child support unit 350 can be used with or without the second child support unit 370, but the second child support unit is not configured for use apart from the first child support unit. In this manner, a caregiver cannot use the second child support unit 370 independent of the play yard on a potentially unsafe support surface. In alternate embodiments, either or both of the first and second child support units can be configured for use independently and separate from the other, or alternatively relying on one another for support.

In example embodiments, as depicted in FIG. 5, the first child support unit 350 is mounted to the frame 302 of the play yard with two channel mounts 330 and L-shaped mounting bars 360. The first child support unit 350 is configured such that its length is parallel with the end cross-members 312 of the frame 302 when mounted to the play yard. The first end of each mounting bar 360 attaches to the first child support unit subframe 352. The second end of each mounting bar 360 includes a female channel coupling portion 332 of the channel mount 330. A corresponding male rib portion 334 of the channel mount 330 is attached to each of two upright corner posts 304 on either side of the width of the play yard frame 302. Each mounting bar 360 is engaged with the corresponding corner post 304 by engaging the female portion 332 and male portion 334 of the channel mount 330, as shown in FIG. 7. In alternate embodiments, the second end of the mounting bar 360 comprises a male rib and the upright corner posts 304 comprise the female channel portion of the channel mount 330, or other coupling formats can be utilized.

The second child support unit 370 is attached for support on one side (its inboard side) to the first child support unit 350 with one or more detachable couplings, and in the depicted embodiment by two dove-tail joint detachable couplings 362 positioned at confronting spaced locations on adjacent inboard sides of the first and second child support units. The second child support unit 370 is configured such that its length is generally parallel to the end cross-members 312 of the frame 302, and generally parallel with the first child support unit 350, when deployed for use. As depicted in FIG. 6, the couplings 362 comprise a first coupling element attached to the side sub-frame component of the first child support unit subframe 352 and a cooperatively engaging second coupling element attached on an adjacent corresponding position of the side sub-frame component of the second child support unit subframe 372. Alternatively, the couplings can be configured to support between end, side or other sub-frame components of the first and or second child support units. The couplings 362 are attached to the first child support unit subframe 352 on the side opposite from which the corner post mounting bars 360 extend. In example embodiments the couplings 362 comprise slidingly engaging dovetail joint couplings, snaps, channel and rib couplings, clips, hooks, magnetic couplings or other detachable coupling members, which allow the second child support unit 370 to be securely connected to the first child support unit 350 when deployed for use in connection with the play yard, and to be easily detached and removed from the first child support unit when not in use to allow access to the play yard.

When deployed for use, the second child support unit 370 is also supported on its other side (its outboard side) by an upright support member 376. In the depicted embodiment, the support member 376 is a U-shaped bar with its ends attached to the second child support unit sub-frame 372 on the side opposite from which the corner-post coupling bars 360 extend. When the second child support unit 370 is deployed for use in the play yard, the cross bar of the U-shaped support member 376 extends downwardly, generally perpendicular to the second child support unit sub-frame 372, into contact with the bassinet mattress 340 or other portion of the play yard to support the second child support unit 370 in a substantially horizontal position over the play yard. The support member 376 of the second child support unit 370 is optionally pivotally or hingedly mounted to the second child support unit sub-frame 372, so that it can be folded flat with the sub-frame for compact storage or transport when detached from the play yard and not in use. In example embodiments, the first child support unit 350 is a changing table or other child support element intended for longer term use in connection with the play yard, and thus configured for use independent of the second child support unit 370; whereas the second child support unit is a sleeper or small bassinet, intended for shorter term use so that it can be removed from connection with the play yard when a child outgrows the second child support unit, to allow easier access to the main containment area of the play yard.

FIGS. 8 and 9 show a child support system 400 according to another example embodiment of the invention. In this embodiment, the first child support unit 450 is supported through engagement with one or more side cross-members 410 and/or an end cross-member 412 of the play yard frame 402. The second child support unit 470 is supported through engagement with the first child support unit 450 and a support member 476 which engages with the raised bassinet mattress 440.

As depicted in FIG. 8, the first child support unit 450 is removably engaged with the side cross-members 410 of the frame 402 through couplings 456 attached to each end sub-frame component of the first child support unit subframe 452. The first child support unit 450 is configured such that its length is parallel with the end cross-members 412 of the frame 402. The couplings 456 at the ends of the subframe 452 releasably engage with the respective side cross-member 412 of the child containment device frame 402. Alternate embodiments comprise alternative arrangements of couplings.

The second child support unit 470 is releasably mounted to the first child support unit 450 using two mounting bars 460. The second child support unit 470 is arranged so that its length is parallel to the end cross-members 412 of the frame 402 and it is positioned adjacent to the first child support unit 450. The first end of each mounting bar 460 is releasably attached to the first child support unit subframe 452 such that the mounting bars 460 are parallel with the side cross-members 410 of the frame 402. The second end of each mounting bar 460 is releasably engaged with the subframe 472 of the second child support unit 470. The mounting bars 460 attach at the ends of the sub-frames 452, 472. In alternate embodiments the mounting bars 460 are permanently attached to either the first child support unit 450 or second child support unit 470 and releasably attached to the other. The second child support unit 470 is also supported by a support member or stand 476. The support member 476, shown in FIG. 9, has two L-shaped bars and a U-shaped base. The ends of the L-shaped bars attach to the second child support unit subframe 472. The base of the support stand 476 rests on the raised bassinet mattress 440 and supports the second child support unit 470 in a substantially horizontal position. The support member 460 is configured so that when the second child support unit 470 is detached from the first child support unit 450, it can be used independently of the child support system 400 supported only by the support stand 476.

FIG. 10 shows a child support system 500 according to another example embodiment of the invention. In this embodiment, the first child support unit 550 is supported through engagement with one or more side cross-members 510 and/or an end cross-member 512 of the frame 502. The second child support unit 570 is supported through engagement with the first child support unit 550 through mounting bars 560.

The first child support unit 550 is removably attached to the side cross-members 510 of the frame 502 with detachable couplings 556. The first child support unit 550 is configured such that its width is parallel with the side cross-member 510 of the frame. Each coupling 556 comprises two engagement clips. The first engagement clip is snapped onto the end sub-frame component of the first child support unit subframe 552 and the second engagement clip is snapped onto the side cross-member 510 of the frame 502.
