RELATED APPLICATIONS [0001] This application is a Continuation in Part Application of a patent application for a Collapsible Play Yard, filed Jul. 30, 2004 (Ser. No. ______ not yet assigned). FIELD OF INVENTION [0002] The field of the invention generally is collapsible play yards or playpens and more particularly to releasable locking mechanisms for such collapsible devices. BACKGROUND [0003] A collapsible play yard provides a portable but stable structure in which a small child can play and sleep. The essential features for such a structure is that it be (1) lightweight enough to carry by one person, (2) easy to set up, and (3) stable enough to safely support the child. An example of a portable play yard is shown in U.S. Pat. No. 4,811,437 to Dillner et al. [0004] The Dillner play yard uses a center hub about which the uprights of the play yard are pivoted. The hub employed in the Dillner play yard is a complex device and the need exists for a simpler center hub design. [0005] Similarly, Dillner provides a play yard having upper rails comprised of several moving parts and a need exists for a simpler upper rail design. SUMMARY [0006] The foldable play yard overcomes the drawbacks of the prior art. The play yard has a hub movable between a raised position and a lowered position, with at least two lower rods pivotally joined to the hub, wherein when the hub is lifted toward the raised position, the outer ends of the lower rods move together so as to be substantially parallel, and when the hub is pushed toward the lowered position from the raised position, the outer ends of the lower rods are pushed away from each other until the rods lie substantially in a common plane. The play yard also has an upper frame with upper frame rods substantially parallel to the lower rods when the hub is in the lowered position. Finally, the play yard has at least one of the upper frame rods pivotable between a raised and lowered position, the pivoting axis being substantially perpendicular to an axis of the vertical rails. BRIEF DESCRIPTION OF THE DRAWING(S) [0007] FIG. 1 is an isometric view of the erected play yard. [0008] FIG. 2 is an isometric view of the collapsed play yard. [0009] FIGS. 3, 3a, and 3b are isometric views that illustrate the sequence of moving the frame between the erected and the collapsed position in FIG. 3b. [0010] FIG. 4 is a side elevation view of the frame of FIG. 3. [0011] FIGS. 4A, 4B, and 4C illustrate an alternate embodiment of the frame. [0012] FIG. 5 is a fragmentary view showing the center hub of FIG. 3 in greater detail. [0013] FIG. 6 is a side elevational view of the center hub of FIG. 5. [0014] FIG. 7 is a cross section of the center hub looking in the direction of arrows 7-7 of FIG. 6. [0015] FIG. 8 is a cross section of the center hub of FIG. 6 looking in the direction of arrows 8-8 of FIG. 7. [0016] FIG. 9 is an enlarged cross section of the center hub looking in the direction of arrows 9-9 of FIG. 8. [0017] FIG. 10 is an isometric fragmentary view illustrating the center hub in a collapsed condition. [0018] FIG. 11 is a cross section of the center hub looking in the direction of arrows 11-11 of FIG. 10. [0019] FIG. 12 is a cross section of the center hub looking in the direction of arrows 12-12 of FIG. 11. Continue reading about Collapsible play yard...
