A playpen includes an upper frame assembly including a corner joining part, a standing leg pivotally connected with the corner joining part, the standing leg being rotatable relative to the corner joining part between a folded position where the standing leg is folded toward the upper frame assembly and an unfolded position where the standing leg is deployed for providing standing support on a floor surface, and a locking mechanism disposed adjacent to the corner joining part, the locking mechanism having a latch operable to lock the standing leg in the unfolded position and to unlock the standing leg for rotation of the standing leg between the unfolded position and the folded position.

A mattress for a children's playpen or play-yard product using a hard substrate layer and an inflatable bladder to improve comfort, the hard substrate layer including a plurality of rigid substrate sections rotateably attached to one another allowing the mattress's hard substrate layer to lie flat when in use as a mattress and to fold into multilateral shapes when in use as a carrying case, the inflatable bladder improving the comfort of the mattress when inflated and in use as a mattress and still allowing the mattress to operate as an effective carrying case when deflated. The children's playpen or play-yard product also includes a collapsible frame assembly with an air compressor mounted thereto, in preferable embodiments, the air compressor being detachably connectable to the mattress's inflatable bladder to quickly inflate and/or deflate the mattress to facilitate its multifunctional use.

A foldable play yard includes a floor assembly including a latch, a top rail assembly and a corner post assembly. The corner post assembly includes a first column and a second column movable relative to the first column. A lower end and an upper end of each of the first column and the second column are respectively movably connected to the floor assembly and the top rail assembly. The latch is pivoted to the lower end of the first column for engaging with the second column, so as to stop the second column from moving relative to the first column for preventing the foldable play yard from being folded. The floor assembly drives the second column to move relative to the first column to drive the top rail assembly to be folded or unfolded when the floor assembly is folded or unfolded.

A system includes a support frame of a foldable playard, and bassinet fabrics attached to the support frame of the playard. The support frame includes a central hub and a plurality of rods, each of the rods having a first end pivotably attached to the central hub and a second, free end opposite the first end. The support frame is configured to enable the bassinet fabrics to fold with the foldable playard.

A foldable play yard includes a plurality of corner posts; a plurality of top rails, each of the top rails rotatably connected to two of the plurality of corner posts to define a polygonal shape; a plurality of reversing links, each of the plurality of reversing links rotatably connected to one of the plurality of corner posts; a central hub; a plurality of lower linkage assemblies, each of the lower linkage assemblies rotatably connected to one of the plurality of reversing links and rotatably connected to the central hub; and a plurality of post linkage assemblies, each of the post linkage assemblies rotatably connected to one of more of the top rails and rotatably connected to one of the reversing links. Lowering the central hub causes each of the lower linkage assemblies to rotate relative to the corner posts in a first direction.

A crib liner constructed of breathable material having a reduced suffocation resistance level for infant and toddler use. In some configurations, the breathable material may include an inner fabric, outer fabric, and a pile substructure between the front and back substructures, thereby allowing air to move effectively therethrough.

A collapsible ground sheet has a floor made of a sheet of flexible, waterproof or water-resistant material, and walls attached to the floor and extending from the floor in a top direction. The walls are arranged about the periphery of the floor in series in a ring formation such that each of the walls has two neighboring walls. Each wall has a fabric portion and a wire loop, the wire loop disposed near the periphery of the fabric portion such that the fabric portion is supported by the wire loop. Each of the walls attached to its two neighboring walls by hourglass-shaped gussets made of a sheet of flexible material.

A playpen frame for an easy-to-install enclosure includes four support assemblies, two long handrail tubes, two short handrail tubes and a bottom frame. The four support assemblies are distributed at four corners, and each of the support assemblies includes a support base, a support post, a slat and a pivoting piece. A height of the support post is identical to a height of the slat. The slat is located outside the support post, and a gap is arranged between the support post and the slat. The support post and the slat are arranged between the support base and the pivoting piece. The two long handrail tubes are arranged opposite to each other, and the two short handrail tubes are arranged opposite to each other. The long handrail tube or the short handrail tube is arranged between two adjacent pivoting pieces of the four support assemblies.

An enclosure for an infant playpen includes a flexible material installable on a support frame of the infant playpen, the flexible material including at least one pleat comprised of two folds that are folded toward each other over a base region of the flexible material and respectively have two folded edge portions adjacent to each other, each of the two folded edge portions having at least one end affixed to the flexible material. Moreover, some embodiments provide an infant playpen that includes a support frame and the enclosure installed thereon.

The present playyard floor apparatus includes a lower floor that is essentially one-piece with a flexible pen and an upper floor that is removably engaged to the lower floor with a quick connect mechanism. The quick connect mechanism has inner and outer portions. The inner portion of the quick connect mechanism is disposed on the underside of the upper floor and spaced from a periphery of the upper floor. The outer portion of the quick connect mechanism is engaged to a periphery of the lower floor and includes interlocking elements that are spaced from the periphery of the lower floor. The upper floor is resilient and extends over the inner and outer portions of the quick connect mechanism and further extends to the sidewall of the flexible pen.
