Description
TECHNICAL FIELD

The present invention relates generally to play yard enclosures for children, and more particularly to a play yard configured for providing an enclosed space for a child and having a removable liner.


BACKGROUND

A play yard is a containment device often used for providing a partially enclosed space for a child to play and rest in. Typically, play yards include a structural frame having upper and lower horizontal frame members joined by vertical frame members. A floor panel and sidewalls are usually defined in between the frame members along with an upper opening through which a child may be placed in and moved out of the play yard. The sidewalls and floor panel are often comprised of a fabric material attached onto the frame members. In addition, the frame members may be collapsible or hinged, such that the play yard can be folded or collapsed into a compact configuration to allow for easier portability and storage of the play yard. U.S. Pat. Nos. 6,859,957, 7,568,242 and U.S. Patent Application Pub. No. 2010/0132115, which are incorporated herein by reference, disclose example forms of play yards.


Typical known children's play yards comprise a frame and a liner permanently secured to the frame. Because the liners are permanently affixed to the frame, they can be difficult to clean when the liner becomes soiled. Thus, there exists a need for an improved play yard that comprises a frame and a removable, washable liner. It is to the provision of an improved children's play yard meeting these and other needs that the present invention is primarily directed.

As shown, the vertical frame members 104 are positioned at the vertical edges of the frame 100 and include feet 106 configured to rest on a support surface 108 (e.g. a floor), and are generally perpendicular to the horizontal frame members. The upper horizontal frame members and lower horizontal frame members 102 are connected at different heights along the vertical frame members 104 such that they are vertically spaced from one another. The upper horizontal frame members extend between adjacent vertical frame members 104, thereby forming a substantially rectangular upper perimeter of the frame 100, defining an upper access opening into the contained volume of the frame. The lower horizontal frame members 102 are positioned inwardly from the vertical frame members 104 and are optionally connected to one another at one or more points to form a lower support surface spaced above the support surface 108. In the depicted embodiment, the lower horizontal frame members 102 comprise diagonal cross-pieces extending between opposite corners of the frame, and/or transverse cross-pieces extending side-to-side or front-to-back. The terms “horizontal” and “vertical” are used herein to indicate components that are substantially horizontally or vertically oriented with respect to a support surface in the typical configuration for use, and are not intended to indicate that particular components must be strictly or entirely horizontal or vertical. In example embodiments, the frame members are substantially rigid rods, bars, tubes, beams or other structural members formed of aluminum, steel, plastic or other structural material(s), and are optionally connected together by hinges, pin joints, coupling members, or other connection or coupling means.


As shown, the frame 100 may include one or more padded members 110 configured to be secured to the upper horizontal frame members. As shown in the illustrated embodiment depicted in FIG. 1, the padded members 110 optionally form a single, unitary padded structure and include a secondary fastener, such as, a row of zipper teeth 112 disposed continuously around an inner portion of the padded members 110. In a particular commercial embodiment, the padded members 110 are permanently attached to the upper horizontal frame members 104 during the manufacturing process. In another embodiment, the padded members 110 are configured to be secured to the upper horizontal frame members 104 by a user (e.g., by wrapping the padded members 110 around the upper horizontal frame members 104 and securing them in place with conventional fasteners, such as snaps, ties, buckles, zippers, or hook and loop fasteners); or alternatively the padded members 110 may be permanently coupled to, integrally formed with, or removably attached to the liner 116. In embodiments where the frame 100 is configured to convert between a collapsed orientation and an erect orientation, the padded members 110 may be configured to bend and fold with the upper horizontal frame members as they are collapsed or expanded, for example by means of one or more gussets, cutouts, flexible segments, or the like. Alternatively, the padded members 110 may comprise a number of separate, individually secured components (as opposed to the single, unitary structure of the depicted embodiment). Further, in additional alternative embodiments, one or more unpadded members having the same or similar structure to the padded members 110 may be used with, or in place of, the padded members 110.


According to certain example embodiments, the frame 100 includes one or more primary fasteners—such as the hooks 114 shown in FIG. 1—coupled to the vertical frame members 104 and configured to removably engage the play yard liner 116.

Furthermore, the frame 100 may include more or fewer primary fasteners and the primary fasteners may be alternatively positioned.



FIGS. 2 and 3 illustrate a play yard liner 116 according to an example embodiment of the present invention. The play yard liner 116 is configured to be removably secured to the frame 100 (as shown in FIG. 4). In the illustrated embodiment, the liner 116 is a unitary fabric enclosure generally defined by four sidewalls 118 (118a-118d) and a floor panel 120. Preferably, the sidewalls 118 are at least partially formed from a mesh material to allow for air flow through the sidewalls 118 and to permit a caregiver to see through to the interior of the play yard 136. Together, the sidewalls 118 and floor panel 120, when mounted to the frame, define a partially enclosed area having an upper opening and a generally rectangular cross-section, defining a three-dimensional rectangular prismatic contained space therein. Collectively, the tops of the sidewalls 118 define an upper perimeter 122 of the open top of the liner 116. According to certain embodiments, secondary mating fasteners—such as mating zipper teeth 124—are disposed along the upper perimeter 122, which are configured to mate with cooperating secondary fasteners on the padded members 110. The liner 116 further includes one or more primary mating fasteners—such as loops 126—attached to the outer surface of the liner 116 at corner portions of the liner's vertical edges and configured to connect or mate with the primary fasteners (e.g. hooks 114) on the vertical frame members 104. According to various embodiments, the loops 126 are generally dimensioned to be slid over the hooks 114 of the play yard frame 100 to secure the liner to the play yard frame 100. In the depicted embodiment, the liner comprises three loops 126 extending outwardly from each corner of the liner, one proximal the top, one proximal the bottom, and one about midway between the top and bottom; and the vertical frame members each comprise three correspondingly positioned hooks. Alternate embodiments include one, two, four or more sets of cooperating fasteners. In alternate embodiments, the primary mating fasteners of the liner 116 can comprise buckles, ties, hooks, snaps, hook-and-loop fasteners, clamps, zippers, or other fasteners, connectors, couplings or other attachment or fastening means configured to releasably couple or attach with the corresponding primary fasteners of the frame 100. In example embodiments, the primary mating fasteners of the liner and the corresponding primary fasteners of the frame engage with and disengage from one another upon manual actuation by an adult user with light to moderate hand pressure, and without tools. In alternate embodiments, a release handle or tool is provided to assist in engagement and/or disengagement of the fasteners.


As shown in FIG. 3, the liner 116 further includes a flap panel 128, which extends outwardly from the liner's upper perimeter 122. In various embodiments, the flap panel 128 is a fabric panel having an inner edge 130 that extends along the liner's upper perimeter 122. The flap panel 128 further includes an outer edge 132 having a curved profile in which portions of the outer edge 132 adjacent the liner's corners extend further from the inner edge 130 than medial portions of the outer edge 132. The flap panel may also include one or more flap fasteners 134 configured to secure the flap panel to the frame 100. Optionally, the flap panel is at least partially formed of an elastic material, to facilitate stretching the flap panel over the frame during installation.
