Abstract

The present invention is a foldable table structure, which is comprised of a fore-board, a backboard and two connection rods. Wherein, two symmetrical concave troughs are arranged at the connection side of the fore-board and the interior of the concave troughs each has a folding plane and an unfolding plane. Corresponding to two concave troughs of the fore-board, two concave troughs are arranged at the connection side of the backboard and each interior of the concave troughs also has a folding plane and an unfolding plane. The connection rod has a fore-end and a back-end. The fore-end is pivotally connected inside the interior of the concave trough of the fore-board and the back-end is pivotally connected inside the interior of the concave trough of the backboard. When the table is unfolded, the connection side of the fore-board is connected against to the connection side of the backboard, and the connection rods contact flatly with the unfolding planes of the fore-board and keep an appropriate angle with the unfolding planes of the backboard. When the table is folded, the backboard is rotated unto the fore-board to make the connection rods contact flatly with the folding planes of the fore-board and the backboard.

Dependent claims

A foldable table structure includes:

a fore-board, which has a connection side and at least one concave trough capable of receiving a connection rod, said concave trough being arranged at said connection side, said concave trough further having an interior which includes a folding plane and an unfolding plane;
a backboard, which has a connection side corresponding to said fore-board and at least one concave trough capable of receiving a connection rod, the concave trough of the backboard being arranged at said connection side of said backboard, interior of said concave trough of said backboard also has a folding plane and an unfolding plane;
and
a connection rod, which includes a fore-end and a back-end, wherein said fore-end is pivotally connected to the interior of said concave trough of said fore-board and said back-end is also pivotally connected to the interior of said concave trough of said backboard;
wherein, when said table is unfolded, said connection side of said fore-board is contacted with said connection side of said backboard, and said connection rod contacts flatly with said unfolding plane of said fore-board and contacts flatly with said unfolding plane of said backboard;
when said table is folded, said backboard is rotated up onto said fore-board and makes said connection rod contact flatly with said folding planes of said fore-board and said backboard.
