A crib having a number of upper rods, lower rods and poles securely connected therebetween. The crib is further provided with foldable devices each pivotally connected between two distal ends of the upper rods, plates each pivotally receiving the other two distal ends of said upper rods and securely receiving a distal end of the pole, seats each securely receiving the other end of the pole and pivotally receiving two distal ends of the lower rods, pivoting blocks each pivotally receiving the other two distal ends of said lower rods and a cover enclosing all of the upper rods, the poles and the lower rods and provided with a handle disposed thereon, such that a user is able to fold the crib by lifting upward the handle of the cover after the foldable devices are activated by the user.

[ What is claimed is:] [1.] A crib comprising a set of upper rod pairs each having a first distal end and a second distal end, a set of lower rod pairs each having a first distal end and a second distal end, a plurality of poles respectively and securely connected with said second distal ends of said upper rods via a plate and with said second distal ends of said lower rods via a seat, a plurality of foldable devices pivotally connected between two first distal ends of said upper rods, more than one pivoting block between each connecting pair of said lower rods and a cover enclosing said upper rods, said poles and said lower rods, wherein the improvements are:a first distal end of each of said upper rods being provided with a flange;said foldable devices having:a housing defining therein two cutouts for pivotally receiving two adjacent first distal ends of said upper rods and having two positioning studs rigidly mounted therein, a first long hole and a second long hole;two controlling blocks pivotally received within said housing wherein each of said controlling blocks is configured to have a stop engageable with said flange of said upper rod, an extension defining therein an inclined slot and a hole for connecting with an end of a recovery device wherein another end of said recovery device is securely connected with one of said positioning studs;a press board movably received within said housing and defining therein a space for receiving said two controlling blocks therein, and a first through hole and a second through hole corresponding to said first long hole and said second long hole;a first retainer extending through said first long hole of said housing and said second through hole of said press board to securely mount said press board onto said housing;a second retainer extending through said second long hole of said housing, said first through hole of said press board and two said inclined slots partly aligned together and mounted to a face of said housing;said seat having a distal end of one of said poles securely received therein and being defined therein two compartments for pivotally receiving two second distal ends of said lower rods.
