Foldable bed assembly

A foldable bed assembly, comprising:

• a first frame unit including two first longitudinal frames which extend along a longitudinal direction and each of which has an inner end portion and an outer end portion, and a first transverse frame which extends along a transverse direction transverse to the longitudinal direction and which interconnects said outer end portions of said first longitudinal frames;
• a second frame unit including two second longitudinal frames which extend along the longitudinal direction and each of which has an inner end portion adjacent to a respective one of said inner end portions of said first longitudinal frames and an outer end portion, and a second transverse frame which extends along the transverse direction and which interconnects said outer end portions of said second longitudinal frames;
• two hinge units pivotally interconnecting said first frame unit and said second frame unit, each of said hinge units being disposed between a respective one of said inner end portions of said first longitudinal frames and a corresponding one of the inner end portions of said second longitudinal frames, and including a hinge member that includes two interconnecting walls spaced apart from each other along the transverse direction and a base wall interconnecting said interconnecting walls, each of said interconnecting walls including a first hinge portion pivotally connected to a corresponding one of said inner end portions of said first longitudinal frames and a second hinge portion pivotally connected to the corresponding one of said inner end portions of said second longitudinal frames;
• and
• a leg unit including at least two frame legs that are detachably and respectively connected to said first frame unit and said second frame unit, and two hinge legs that are detachably and respectively connected to said base walls of said hinge members of said hinge units;
• said second frame unit being pivotable relative to said first frame unit and convertible between a normal state, where said first transverse frame is spaced apart from said second transverse frame along the longitudinal direction, and a folded state, where said second longitudinal frames are respectively overlaid on said first longitudinal frames and said first transverse frame is overlaid on said second transverse frame;
• wherein said inner end portion of each of said first longitudinal frames includes two first pivot connecting walls extending along the longitudinal direction and defining a first receiving groove therebetween, and said inner end portion of each of said second longitudinal frames includes two second pivot connecting walls extending along the longitudinal direction and defining a second receiving groove therebetween, each of said hinge members being entirely disposed in said first receiving groove of a corresponding one of said first longitudinal frames and said second receiving groove of a corresponding one of said second longitudinal frames, and being concealed along the transverse direction by said first pivot connecting walls of the corresponding one of said first longitudinal frames and said second pivot connecting walls of the corresponding one of said second longitudinal frames;
• wherein each of said hinge legs has a surrounding wall that surrounds said hinge member of the respective one of said hinge units and that directly abuts against said first pivot connecting walls of said inner end portion of the respective one of said first longitudinal frames and said second pivot connecting walls of said inner end portion of the corresponding one of said second longitudinal frames, such that detachment of said hinge legs from said hinge members of said hinge units permits said second frame unit to move from the normal state to the folded state;
• and
• wherein each of said hinge units further includes a first bolt and a second bolt that extend along the transverse direction, said first hinge portion and said second hinge portion of each of said interconnecting walls being respectively formed with first and second pivot holes, said first bolt of each of said hinge units extending through a corresponding one of said inner end portions of said first longitudinal frames and said first pivot holes of said interconnecting walls of a corresponding one of said hinge members so that said first longitudinal frame is pivotable about said first bolt, said second bolt of each of said hinge units extending through a corresponding one of said inner end portions of said second longitudinal frames and said second pivot holes of said interconnecting walls of a corresponding one of said hinge members so that said second longitudinal frame is pivotable about said second bolt, said first longitudinal frames being respectively and pivotally connected to said second longitudinal frames.
