This application claims priority of Taiwanese Utility Model Application No. 110209506, filed on Aug. 12, 2021.
The disclosure relates to a bed assembly, more particularly to a foldable bed assembly.
Because it is complicated to assemble components of a conventional bed such as a bed frame, bed legs and a bed panel, the conventional bed is usually assembled in advance in the factory before transportation to a user's place. However, the assembled conventional bed is bulky, occupies a relatively large space in a truck and more manpower and freight are required to transport the conventional bed. Although the components of conventional bed may be transported to the user's place and then be assembled by a technician, the number of components of the conventional bed is quite a lot and the components may be missing during transportation and the procedure of assembling the conventional bed is complicated and time consuming.
Therefore, an object of the disclosure is to provide a foldable bed assembly that can alleviate at least the drawback of the prior art.
According to an aspect of the disclosure, a foldable bed assembly includes a first frame unit, a second frame unit, and two hinge units. The first frame unit includes two first longitudinal frames and a first transverse frame. The first longitudinal frames extend along a longitudinal direction and each of the first longitudinal frames has an inner end portion and an outer end portion. The first transverse frame extends along a transverse direction transverse to the longitudinal direction and interconnects the outer end portions or the first longitudinal frames. The second frame unit includes two second longitudinal frames and a second transverse frame. The second longitudinal frames extend along the longitudinal direction and each of the second longitudinal frames has an inner end portion adjacent to a respective one of the inner end portions of the first longitudinal frames and an outer end portion. The second transverse frame extends along the transverse direction and interconnects the outer end portions of the second longitudinal frames. The hinge units pivotally interconnect the first frame unit and the second frame unit. Each of the hinge units is disposed between a respective one of the inner end portions of the first longitudinal frames and a corresponding one of the inner end portions of the second longitudinal frames and includes a hinge member. The hinge member of each of the hinge units includes two interconnecting walls spaced apart from each other along the transverse direction and a base wall interconnecting the interconnecting walls. Each of the interconnecting walls includes a first hinge portion pivotally connected to a corresponding one of the inner end portions of the first longitudinal frames and a second hinge portion pivotally connected to the corresponding one of the inner end portions of the second longitudinal frames. The second frame unit is pivotable relative to the first frame unit and is convertible between a normal state, where the first transverse frame is spaced apart from the second transverse frame along the longitudinal direction, and a folded state, where the second longitudinal frames are respectively overlaid on the first longitudinal frames and the first transverse frame is overlaid on the second transverse frame.
