A playpen, comprising:
- a top frame having four corners and defining a top opening therebetween wherein said top frame comprises a pair of top joints and a pair of U-shaped top arms each having two inward ends pivotally connected to said two top joints respectively to form a rectangular top opening;
- a bottom frame having a supporting surface, wherein said bottom frame comprises a pair of supporting boards positioned side by side to form a rectangular structure wherein said bottom frame is disposed below and spaced apart from said top frame in a vertical direction;
- a boundary frame which supports said top frame on top of said bottom frame and defining an interior space between said top frame and said bottom frame, wherein said boundary frame comprises two U-shaped side frames and two pairs of stopper means, wherein each of said side frames has two folding ends pivotally connected to said two top joints respectively and outwardly and inclinedly folded to connect said bottom frame at two lower portions thereof, wherein each of said stopper means is pivotally connected between said top arm and said side frame for holding said top arm from a folded position to an unfolded set-up position;
- a boundary shelter supported by said top frame to surround said interior space and define a playpen cavity within said boundary shelter, said top frame and said bottom frame;
- and
- a detachable cot comprising:
- a bottom wall having a size smaller that that of said supporting surface of said bottom frame;
- a surrounding wall upwardly extended from circumferential edge of said bottom wall to define a supporting cavity within said surrounding wall and said bottom wall, wherein said supporting cavity has a depth smaller than a depth of said playpen cavity;
- a side holder, which is provided around an upper portion of said surrounding wall, sidewardly extending to hook on said top frame of said playpen so as to support said detachable cot in an upper portion of said playpen cavity and evenly distribute the weight of the detachable cot on said top frame, and
- a fastening device comprising a plurality of first fastener units spacedly connected to said side holder and a plurality of second fastener units spacedly affixed on an upper portion of said boundary shelter for detachably fastening with said first fastener units respectively so as to securely mount said detachable cot on said collapsible playpen;
- wherein in said unfolded set-up position, said two top arms are pivotally lifted up horizontally to form a rectangular structure, and in said folded position, said two top arms are pivotally dropped down toward to said two side frames respectively, wherein said side holder of said surrounding wall of said detachable cot is formed by folding a top edge portion outwardly to form an outer wall and an inner wall so as to define a mounting groove having a downward opening for receiving said top arms of said top frame, wherein said surrounding wall further has four U-shaped corner opening formed on four corners of said outer wall of said side holder of said surrounding wall.
