This non-provisional application claims priority under 35 U.S.C. 119(a) on Patent Application No. 111200754 filed in Taiwan on Jan. 19, 2022, the entire contents of which are hereby incorporated by reference.
BACKGROUND OF THE INVENTION 1. Fields of the inventionThe present disclosure relates to a foldable bed assembly and, in particular, to a foldable bed assembly with bed frame unit and the bed board unit are pivotable to reduce the volume that the foldable bed assembly occupies so as to reduce the packaging space and transportation space required for shipment.
2. Descriptions of Related ArtIn order to solve the shortcomings of a larger storage space or freight space is required, and a higher freight cost to the conventional bed frame assembly which does not include a proper folding mechanism so that a foldable bed assembly becomes one of solutions adopted by the industry to solve the above-mentioned deficiencies. The conventional foldable bed frame is composed of two main support frames that are pivotally connected to each other, and can be folded relative to each other along the longitudinal direction of the folding bed frame. A mattress is put on the two main support frames to form a basic structure of a foldable bed. When storing or transporting it, the two main support frames are folded to saves storage or transportation space required.
Taiwanese Utility patent No. M621470 discloses a foldable bend frame assembly and includes a first frame unit, a second frame unit and two hinge units. The hinge units are used for pivoting the first frame unit and the second frame unit, and each hinge unit includes a hinge piece which has two spaced apart connecting walls, and a bottom wall is connected to one end of the connecting walls. The connecting wall has a first pivot portion pivotally connected to the corresponding first end portion, and a second pivot portion opposite to the first pivot portion and pivotably connected to the corresponding second end portion. The second frame unit is folded relative to the first frame unit between an unfolded position and a folded position. However, the patent does not have lateral folding function to the end wing support and the end wing bed board. Therefore, the bed frame and the bed board cannot be folded to each other, and the volume of the folded status of the bed frame assembly cannot be further reduced, which increases the transportation cost.
US201800254 discloses a folding bed frame and includes two symmetrically arranged bed frame units which are pivotably connected to each other by hinges. The bed frame unit further includes a plurality of first support rods pivotably connected with the bed frame unit by hinges. The direction that the plurality of first support rods are folded is perpendicular to the direction that the bed frame unit is folded.
US2020205576 discloses a folding bed frame and a bed board put on the bed frame. The bed frame includes a first frame unit and a second frame unit arranged side by side and pivotally connected to each other. The bed board includes a first board unit fixedly located on the first frame unit, and a second board unit fixedly located on the second bed frame unit. Each of the first panel unit and the second panel unit includes one or more panel elements. Each panel element includes a substrate, a sponge layer and a cover. The base plate is located on the first or second frame unit. The sponge layer is arranged on the base material, and the cover layer is arranged on the sponge layer.
US2021337976 discloses a transportable and foldable bed frame, and includes a base including a first frame having a bottom and a top, a second frame has a bottom and a top, and a connector pivotally connecting the second frame to the first frame. The first frame and the second frame selectively pivot relative to each other about a pivot, such that the first frame and the second frame selectively pivot relative to each other between the expanded position and the unfolded position. The top of the first frame and the second frame are substantially coplanar and adapted to support the mattress and to close the folded position. The bottom is folded and the top of the second frame covers the top of the first frame.
US2009249545 discloses a portable and foldable bed frame, and includes a triangular support plate installed at the joint between the rotating rod of the rotating support rod and the connecting rod, so as to enhance the supporting strength of the rotating support rod. The width of the fixed support rod is twice of the width of the bed frame. A contact unit is provided between the fixed plate and the fixed support rod, so as to obtain a stable engagement of the fixed support rod. A foldable spring is located between the lower cross bar of the rod and the outer frame of the bed frame, so that the bed can be conveniently folded.
Each of the U.S. Patented bed assemblies mentioned above is able to be folded along the longitudinal direction, however, none of the four bed assemblies provides wing part wing support members, and none of the four bed assemblies provides the features of foldable wing bed board transversely. In other words, the bed board and bed frame cannot be folded transversely to further reduce the storage space and transportation space, and that will increase the transportation cost.
The present invention intends to provide a foldable bed assembly to eliminate the shortcomings mentioned above.
