ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a combined bench and table, more particularly to a foldable combined bench and table with support frames which are foldable relative to a mounting frame.
2. Description of the Related Art
A conventional combined bench and table includes a table plate, a pair of bench plates, and a support frame to support and secure the table and bench plates. Since these components are not detachable and foldable, the conventional combined bench and table is inconvenient to carry and store.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a foldable combined bench and table which is foldable so as to be stored and transported conveniently.
According to this invention, the foldable combined bench and table includes a pair of support frames. Each support frame includes a bottom rod adapted to be laid on a ground surface and spaced apart from the bottom rod of the other support frame in a longitudinal direction. The bottom rod extends in a transverse direction relative to the longitudinal direction, and has front and rear ends which extend uprightly to form frontmost and rearmost posts for detachably mounting a pair of bench seat members, and an intermediate portion which has a leg member that extends uprightly and that includes first proximate and distal end portions.
A mounting frame is used to mount a flat board member. The mounting frame includes a pair of side rails which are disposed in parallel and which are spaced apart from each other in the transverse direction, rightmost and leftmost crossbars which respectively interconnect right and left end portions of the side rails to define a first axis and which are coupled with the first distal end portions of the leg members such that the first distal end portions are pivoted about the first axis, and right and left crossbars which interconnect middle portions of the side rails.
The support frames is foldable relative to the mounting frame by a pair of linkage assemblies. Each linkage assembly includes upper and lower linking arms which respectively have second proximate and distal ends and third proximate and distal ends. The second distal end of the upper linking arm is hinged to the third proximate end of the lower linking arm about a second axis which is parallel to the first axis. In addition, the second proximate end of the upper linking arm and the third distal end of the lower linking arm are respectively secured to the right or left crossbar, and the first proximate end portion of the corresponding leg member. As such, when the second distal end of the upper linking arm is swung about the second axis to a stretched position, where the upper and lower linking arms are substantially aligned with each other, the corresponding support frame will be placed in an erected and unfolded position so as to put up the mounting frame, and when the second distal end is turned about the second axis to a folded position, where the upper and lower linking arms are out of alignment, the bottom rod of the corresponding support frame will be brought closer to the mounting frame.
