BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates to a rack assembly, more particularly to a foldable rack assembly.
2. Description of the Related Art
Referring to
However, since the components of the conventional rack are not formed integrally, assembly of the conventional rack is complicated and involves many steps as described above. Moreover, the conventional rack provides a limited space for supporting an article, and is not foldable.
SUMMARY OF THE INVENTIONTherefore, the object of the present invention is to provide a rack assembly that is foldable, that is easy to assemble, and that can further permit hanging of articles.
According to this invention, a foldable rack assembly comprises first and second components. The first component includes a back plate and a first shelf plate projecting forwardly from the back plate. The second component includes a second shelf plate connected pivotally to the first component. The second shelf plate is movable relative to the back plate between an unfolded position, where the second shelf plate projects forwardly from the back plate and is coplanar with the first shelf plate, and a folded position, where the second shelf plate is rotated downward and toward the back plate.
BRIEF DESCRIPTION OF THE DRAWINGSOther features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
Referring to
The first component 3 includes a back plate 31, a first shelf plate 32, and a plurality of spaced-apart first hook members 33. The back plate 31 is formed with a plurality of fastening holes 311 for attachment of fasteners (not shown) so as to fix the back plate 31 to the vertical wall surface 2. The first shelf plate 32 projects forwardly from and forms an angle of about 90 degrees with the back plate 31, and has a top surface 321 (see
The second component 4 includes a second shelf plate 42 which includes a top wall 421, a rear wall 411 extending downwardly from the top wall 421, and a corner 422 formed by the top and rear walls 421, 411. The top wall 421 has an indented wall part 412 extending forwardly from the corner 422. The rear wall 411 is formed with a plurality of notches 414 for extension of the first hook members 33 therethrough.
Two spaced-apart mating grooves 413 are provided in the second shelf plate 42. Each mating part 34 of the first component 3 extends into one of the mating grooves 413. The second shelf plate 42 is connected pivotally to the mating parts 34 of the first component 3 so that the second shelf plate 42 is movable relative to the first component 3 between unfolded and folded positions. In the unfolded position, the second shelf plate 42 projects forwardly from the back plate 31 and is coplanar with the first shelf plate 32. In the folded position, the second shelf plate 42 is rotated downward and toward the back plate 31. The detailed configuration to allow for such interconnection and operation will be described below. In this embodiment, the number of the mating grooves 413 corresponds to the number of the mating parts 34.
The second shelf plate 42 further includes two pairs of spaced-apart ribs 43 projecting downwardly from the top wall 421 and forwardly from the rear wall 411, and a bridge member 46 interconnecting each pair of the ribs 43. Each pair of the ribs 43 and the corresponding bridge member 46 define one of the mating grooves 413. The top and rear walls 421, 411 and the corner 422 are notched adjacent to each mating groove 413 so that each mating groove 413 opens at the top and rear walls 421, 411 and the corner 422. Each of the ribs 43 has a bottom edge extending away from the top wall 421, and is formed with a slot 44 to engage pivotally the pivot member 342 of the corresponding mating part 34. The slot 44 has an open end 441 opening at the bottom edge of the corresponding rib 43.

Referring once again to
From the aforementioned description, it is apparent that the foldable rack assembly of the present invention is easy to assemble since each of the first and second components 3, 4 is integrally formed, and since the first and second components 3, 4 are readily interconnected. In the unfolded position, the top surfaces 321, 421 of the first and second components 3, 4 can support an article thereon. In the folded position, the second component 4 can be folded downward from the first component 3, so that it does not occupy much space. Further, through the presence of the first and second hook members 33, 45, and the through holes 451, additional articles can be hung on the foldable rack assembly of the present invention.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
