A collapsible baby playing bed is provided. The baby bed includes an upper frame and a lower frame coupled together with four corner joints, four leg bases, and four legs. The upper frame consists of four horizontal sides, each side being made of two rods connected together by a bending joint at the center of the side. The lower frame consists of two crossing rod units, four bending joints, and two connecting rods connecting a straight rod with a curved rod of each crossing unit. Two movable bases are included with each having a foot to stand on the ground, and being connected with a respective connecting rod. Two locking bases are also provided, each having a foot to stand on the ground and being connected with a respective straight rod. The lower frame is capable of being collapsed, which in turn permits the upper frame to be collapsed.

A collapsible baby playing bed comprising: an upper frame having four horizontal sides, each of said horizontal sides being formed of two rods connected with a bending joint and four corner joints, each of said corner joints pivotally connecting two neighboring horizontal sides and a vertical leg; four bending joints, each bending joint including (1) a right half joint having a tubular portion for receiving a respective one of said two rods of a respective horizontal side of said upper frame, a round inner tooth portion and a central through hole formed in a side thereof, (2) a fitting block having a plurality of projecting teeth extending radially outward, said teeth engaging with inner teeth formed in said inner tooth portion of said right half joint, said fitting block having a central recess formed in a right side wall thereof and two opposing sectorial recesses, (3) a spring disposed between said side of said right half joint and said fitting block, one end of said spring being disposed within said central recess, (4) a left half joint having a tubular portion for receiving a respective one of said two rods of said horizontal side of said upper frame, said left half joint having a round case portion for receiving a push cap in an open side thereof and two opposing sectorial projections formed on a right side wall thereof to engage said sectorial recesses of said fitting block, said left half joint further having a central hole formed through said right side wall and two through holes formed on opposing sides of said central hole for receiving two locking bolts extending from said push cap, said through holes each having a recessed step for matingly receiving a hook portion of each of said locking bolts to lockingly engage said push cap, (5) a bolt and a nut threadedly engaged to said bolt, said bolt passing through said central through hole of said right half joint and said central hole of said left half joint to couple each to the other, and (6) said push cap being provided to fit in an open side of said round case portion of said left half joint to thereby angularly adjust said left half joint relative to said right half joint; said four corner joints being bent for 90 degrees and pivotally connected with two neighboring rods of said four horizontal sides of said upper frame to form said upper frame into a rectangular shape, each of said corner joints being firmly connected with a respective one said four legs; said four legs being vertically and firmly connected with said corner joints and supported by four leg bases on a base surface; each of said four leg bases being connected to a bottom end of a respective one of said four leg bases to stand on the base surface; a lower frame including two crossing rod units, two connecting rods, four middle joints, two locating bases and two movable bases; each of said two crossing rod units including a straight rod and a curved rod crossingly and pivotally connected together, outer ends of said two straight rods and said two curved rods being pivotally connected with respective projecting plates of said four leg bases, inner ends of said straight rods and said curved rods being pivotally connected with said middle joints, said inner ends of each of said straight and curved rods being formed with slotted through openings for receiving bolts therein to couple said straight rods and said curved rods with said middle joints; each of said four middle joints having a tubular portion for receipt within a respective one of said straight or curved rods and a lateral hole for receiving a bolt to couple said middle joint therewith, each of said middle joints having a linking portion provided with a front sloped locking surface and a lateral hole for a bolt to couple said middle joint with one said connecting rod; said two locating bases being shaped as a T and having a curved-down surface in a horizontal portion for supporting said curved rod, each of said locating bases having a hole formed in said surface for receiving a bolt to couple said bases to said curved rods, each of said locating bases having a vertical portion defining its vertical portion; said two connecting rods each having two horizontal grooves and a pivot hole formed in opposing ends thereof and an annular groove intermediate said opposing ends; said two movable bases each having a C-shaped notch at one end and a flat plate portion formed on an opposing end of a horizontal portion thereof and a vertical portion defining a leg; and, each said linking portion of each said middle joint fitting in said horizontal grooves of each said connecting rod and being pivotally connected together with a bolt, each said C-shaped notch of each said movable base movably engaging said annular groove of said connecting rod, a cloth pull slip provided to protrude through a bottom cloth of a bed cover and being bound on said two connecting rods, a bed mattress being laid on a bottom formed by said lower frame, and thereby forming a baby playing bed.
