ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a table made of paperboards. The paperboards includes four base parts, a cruciform frame and a top which are engaged with each other by inserting one paperboard into slits in the other paperboard.
BACKGROUND OF THE INVENTION
A conventional table suitable to be carried outdoor generally is made of metal tubes and a board which is pivotably connected to the metal tubes. The table can be folded to become a compact size so as to be conveniently carried or put in trunk of a car. Nevertheless, the conventional foldable table is still heavy in weight and the space that the folded table occupies is large. The connection between the tubes uses a lot of hooks, links or the like and these small parts could hurt the users' fingers. Furthermore, the foldable table is not a homogenous shape because there are a lot of protrusion portions such as the legs which make the foldable table be difficult to be properly stored in a limited space such as the trunk of a car.
The present invention intends to provide a foldable table that is made of paperboards which are engaged with each other by inserting one paperboard into slits in the other paperboards. The paperboards are easily to be disengaged from each other and can be overlapped with each other to become a thin pile of paperboards.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a paperboard table comprising two first paperboards each having two first slits defined in a lower edge thereof. Two first side slits are respectively defined in two sides of each first paperboard. Two second paperboards each have two second slits defined in the top edge thereof and two second side slits are defined in two sides of each second paperboard. The two first paperboards are respectively connected between the two second paperboards by inserting the two first paperboards into the two second slits. A top has four sides and each side has a side flap extending therefrom. Each side flap has two engaging slits defined in a distal edge thereof The top is removably located on the respective top edge of the two first paperboards and the two second paperboards. The side flaps are respectively folded and the engaging slits of the side flaps are engaged with the first side slits of the two first paperboards and the second side slits of the two second paperboards.
The object of the present invention is to provide a table that is composed by paperboards so that the table has light weight and can be easily assembled and/or disengaged apart.
Another object of the present invention is to provide a table that can be disengaged into sheets of paperboards which are piled to become a compact size.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
