PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:
FIELD OF THE INVENTION :
This invention relates to the field of mechanical engineering, particularly to articles of furniture.
More particularly this invention relates to articles of furniture of the type adopted to be conveniently converted in to at least one form selected from ottoman, a table or a desk or a bed and combinations thereof.
Specifically, this invention relates to foldable multipurpose domestic appliances,
BACKGROUND OF THE INVENTION :
In the present era of modernization, everybody wishes to have all kinds of furniture and also wishes to have purpose specific furniture which makes life easy and comfortable. Furniture is the mass noun for the movable objects intended to support various human activities such as seating, sleeping, and the like.
Most of the furniture assemblies available in art and market are single-purpose. Some of them are transformable into secondary purpose also. Some other known furniture assemblies available in art are dual purpose, for example, sofa beds and futon couches, which serve as seating devices and are transformable into beds. Chairs and couches are used to sit on; beds to sleep, rest or otherwise recline; tables for work surfaces, or eating or meeting space; cabinets, shelves and drawers for storage or display.
US 3,726,535 discloses a multi-purpose article of furniture which doubles as a portable bar, a TV carrier, a magazine rack, a coffee table or a seat and consists
of a box-like body with removable tray-like lid, said lid having a bevelled perimeter which mates with the edges of the vertical walls. The floor may have a sunken portion and the casters for the body may be replaced with U-shaped connectors which permit the arrangement of a plurality of articles into aesthetically different combinations.
US 4,783,118 discloses an article of children's furniture useful as a rocker in a first orientation and useful as a high-chair or as a desk when inverted. In both such orientations of the article, a child using it has a seat, a back-rest, a foot-rest, and a ledge conveniently located above and ahead of the seat. In the inverted orientation a tray, readily detachable by an adult but not by a child, is attachable above the ledge as a location for food or for toys or for use as a writing surface. Casters, attachable to the article when in the rocker orientation, facilitate movement of the article when in the inverted position—but not by a child seated therein, who is too short to reach the floor and double as toys in the rocker orientation. This article of furniture is stable in both its rocking and inverted orientations, and supports a child securely.
US 6,367,874 discloses multi-functional furniture which can be utilized for a number of different purposes including a bassinet, cradle, bench, desk, rocking bench, high chair, or changing table. All of the furniture articles positions are achieved when combining one or more of the units' actions.
It becomes sometimes difficult to combine and manage all the furniture in one assembly, so that the space limitation problem can be solved.
There is, hence, a need of inter-convertible articles of furniture, which may be contained within a completely enclosed item of furniture, such as an enclosed coffee table, ottoman or desk and which, when unfolded or converter, does not
require the removal of cushions or other portions of the item of furniture to enable the bed to be unfolded and used as a sleeping surface.
OBJECTS OF THE INVENTION :
The primary object of present invention is to provide inter-convertible articles of furniture, which may be contained within a completely enclosed item of furniture, such as an enclosed coffee table, ottoman or desk and which, when unfolded, does not require the removal of cushions or other portions of the item of furniture to enable the bed to be unfolded and used as a sleeping surface.
Another object of present invention is to provide articles of furniture of the type adopted to be conveniently converted in to at least one form selected from an ottoman, a table, a desk, a bed, or its combinations thereof.
Yet another object of present invention is to provide articles of furniture, which can be easily assembled and dissembled.
