Abstract
A portable playyard includes a top frame defining a top opening, a bottom frame, a plurality of circular inflatable supporters spacedly bridging the top and bottom frames, a boundary shelter supported by the top frame to define a playyard cavity within the boundary shelter, the top frame, and the bottom frame; and an air valve provided at the inflatable supporters. Each of the inflatable supporters, having an air chamber, is outwardly and inclinedly extended from the top frame to the bottom frame to evenly distribute and support a downward force applied on the top frame so as to prevent the playyard from being accidentally collapsed.

A portable playyard, comprising:
- a top frame including an inflatable top boundary frame, having an air cavity, defining a top opening therewithin;
- a bottom frame positioning underneath said top frame, wherein said bottom frame comprises an inflatable bottom boundary frame having an air compartment, a circumferential size larger than that of said top boundary frame, and a bottom wall mounted within said bottom boundary frame;
- a plurality of inflatable supporters having a top portion spacedly connected to said top boundary frame and a bottom portion spacedly connected to said bottom boundary frame so as to spacedly bridging said top and bottom frames and defining an interior space between said top and bottom frames, wherein each of said inflatable supporters, having an air chamber, outwardly and inclinedly extends from said top frame to said bottom frame to define an interior adjacent angle and an exterior adjacent angle, wherein each of said inflatable supporters has a tubular shape and a cross section gradually reduced from said top portion to said bottom portion, wherein said cross section of each of said inflatable supporters, which is larger than cross sections of said top boundary frame and said bottom boundary frame, is gradually increased from said top portion to said bottom portion of said inflatable supporter, wherein said interior adjacent angle is defined between an interior peripheral edge of said respective inflatable supporter and said bottom frame and said exterior adjacent angle is defined between an exterior peripheral edge of said respective inflatable supporter and said bottom frame, wherein said both said interior adjacent angle and said exterior adjacent angle are smaller than 90 degrees and said exterior adjacent angle is smaller than said interior adjacent angle;
- a boundary shelter supported by said top frame to surround said interior space and define a playyard cavity within said boundary shelter, said top frame, and said bottom frame;
- and
- at least an air valve provided at said inflatable supporters for retaining a predetermined volume of air within said air chamber of each of said inflatable supporters.
