20090139026Foldable bed - A foldable bed having a frame and a cover attached to the frame. The frame has two handles, two identical side beams each having a pair of groove beams pivotally connected to one of the handles, connectors and bars pivotally connected to the handles or the connectors. The foldable bed is able to be folded by a simple action of pulling the handle upward meanwhile stepping on the peddling member. And it is able to be expanded by a simple action of breaking off the two groove beams with two hands of a user. Furthermore, the foldable bed occupies relatively small storing space when folded since a width of the folded bed is much shorter than that of the expanded one's.06-04-2009
20090140557Foldable table-chair assembly - A foldable table-chair assembly and the frame thereof. The frame has a table frame and four integral chair frames. A table panel is able to be detachably attached on the table frame. The table panel has a plurality of hard sub-panels which are foldably connected together and a covering containing said sub-panels. A chair panel is able to be detachably attached on each chair frame.
