Foldable bed

A foldable bed comprising:

• a base frame unit including a first frame body and a second frame body that are arranged in a front-rear direction and that are pivotally connected to each other;
• a sliding unit disposed on and slidable forwardly and rearwardly relative to said base frame unit, said sliding unit including:
• a first sliding frame that is disposed atop said first frame body in a top-bottom direction transverse to the front-rear direction, and that has a plurality of first rollers slidably disposed on said first frame body such that said first sliding frame is slidable along said first frame body, and
• a second sliding frame that is pivotally connected to said first sliding frame and that is disposed atop said second frame body in the top-bottom direction, said second sliding frame having a plurality of second rollers that are slidably disposed on said second frame body such that said second sliding frame is slidable along said second frame body;
• a bed board unit movably disposed on said sliding unit, said bed board unit including a front bed board and a rear bed board that are arranged in the front-rear direction and that are pivotally connected to each other;
• and
• a linkage mechanism connected to said sliding unit and said bed board unit, said linkage mechanism being operable for driving one of said front and rear bed boards to rotate relative to said base frame unit and to simultaneously drive said sliding unit to slide relative to said base frame unit;
• wherein said foldable bed is operable between an unfolded state, where said first and second frame bodies are aligned with each other in the front-rear direction, and a folded state, where said first frame body, said second frame body, said first sliding frame, said second sliding frame, said front bed board, and said rear bed board are stacked in the top-bottom direction.
