Combined structure made of a foam material

Abstract

A combined structure made of a foam material includes a top panel, two long side panels, two short side panels, and a bottom panel, wherein the top panel at its bottom has a plurality of slots, and the long side panel at its top has two protruding tenons for engaging the slots, and the long side panel includes two penetrating groove holes on both sides for embedding the protruding tenons, and the long side panel at its bottom has a plurality of protruding tenons for fixing the slots at the corresponding positions at the periphery of the bottom panel. The foam material forms a table or a chair capable of storing articles, so as to achieve the effects of providing a convenient and quick installation, a light weight, an easy storage, and a feature of not occupying too much space after the combined structure is disassembled.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a combined structure made of a foam material, and more particularly to a combined structure comprising a top panel, two long side panels, two short side panels, and a bottom panel to form a table or a chair, and the panels can be lifted for containing articles, so as to achieve the effects of providing a convenient and quick installation, a light weight, an easy storage, and a feature of not occupying too much space after the combined structure is disassembled. [0003] 2. Description of the Related Art [0004] In outdoor barbeque activities, we need to prepare a dining table and chairs for placing food and providing seats, in addition the preparation of food. However, the portable table and chairs are usually made of wood, plastics, or aluminum. Although the present material can be folded and stored conveniently, yet wood is considered too heavy, plastics cannot carry heavy loads, and ...

AI Technical Summary

Benefits of technology

[0007] Therefore, it is a primary objective of the present invention to provide a combined structure made of a foam material that comprises a top panel, two long side panels, two short side panels, and a bottom panel, wherein a plurality of slots is disposed at the bottom surface of the top panel, and the long side panel has two protruding tenons protruded from the top of the long side panel and embedded into the slots of the top panel, and the long side panel has two penetrating groove holes disposed on both sides of the long side panel for embedding and fixing the protruding tenons on both sides of the short side panel, such that the size of the foam material is used to combine a table or a chair, so as to achieve the effects of providing a convenient and quick installation, a light weight, an easy storage, and a feature of not occupying too much space after the combined structure is disassembled.

Problems solved by technology

Although the present material can be folded and stored conveniently, yet wood is considered too heavy, plastics cannot carry heavy loads, and aluminum is too expensive.

Furthermore, tables and chairs made of wood, plastic, and aluminum are still heavy for transportation.

Further, the tables and chairs made of these materials are not suitable for indoor uses such as a classroom with many children.

There is always a risk for children to accidentally bump into the hard tables or chairs and get hurt.
