  • Patent number: 8984682
    Abstract: A reversible platform and a crib therewith are disclosed. The reversible platform includes a pivotally-engaging mechanism and a bracket. The pivotally-engaging mechanism is disposed on a crib frame. The bracket is connected to the crib frame through the pivotally-engaging mechanism. The bracket has a first side and a second side opposite to the first side. The bracket is capable of being rotated to be disposed selectively with the first side or the second side facing upward for providing application space. Thereby, the invention can provide two application platforms with one occupied space of the crib frame, so as to solve the issue in the prior art that additional accessories provided for a conventional crib is provided for multiple functions occupy more space and the operation therefor is usually inconvenient to users.
