## Background
FIELD OF THE INVENTION
The present invention relates to modular furniture and more particularly to a modular furniture system particularly suited to the needs of children.
BACKGROUND OF THE INVENTION
Modular furniture assemblies are known in the art. Typical known furniture assemblies include modular furniture bases that may be set on a floor and serve as platforms for supporting several different auxiliary components. The modular furniture bases and the auxiliary components couple together to build different assemblies of furniture, e.g., a chair, a sofa, a table and so on.
For example, U.S. Pat. No. 3,811,728 describes a furniture base assembly, which has a rectangular bottom edge for sitting on the floor, a rectangular top surface positioned above the bottom edge, and a four-sided wall interconnecting the top surface with the bottom edge. The top surface is recessed with several criss-crossed slots. The top surface is also recessed along the four sides of its perimeter with slender, rectangular openings. For coupling two such modules together, there are inverted-U shaped clips, with legs having cross-sections in the shape of slender rectangles, for insertion one apiece into the slender, rectangular openings of the top surfaces. Thus two modules can be coupled together to build a modular assembly of a furniture base. Some auxiliary components couple with the furniture base to build chair or sofa assemblies, or table, shelf or bed assemblies.
U.S. Pat. No. 5,452,554 to Santana describes a modular furniture construction system employing a main body element consisting of a longitudinal element as well as two secondary body elements extending transversely from the longitudinal element. Each of the secondary body elements is provided with a key-shaped guiding hole in which a fastening device is inserted adapted to join two main body elements together. These main body elements can be joined together in a number of different ways to form, along with one or more support elements, various pieces of furniture, such as chairs, tables, desks shelves and other similar devices.
U.S. Pat. No. 6,039,501 to Ruther describes modular furniture which includes a frame and an insert plate to be mounted in the frame by corner fittings. Each corner fitting is detachably mounted on the insert plate and comprises at least one laterally accessible receptacle parallel to the plane of the plate for a retaining pin mounted on the frame as well as a locking mechanism for the retaining pin to be arrested in the receptacle.
U.S. Pat. No. 5,423,597 to Rogers describes a modular furniture assembly for children to build and rebuild their own assemblies of school furniture. The assembly components include, as general categories, base components and interchangeable auxiliary components. The auxiliary components can be releasably coupled with the base components to build school-related assemblies including chair assemblies with adjustably high seating surfaces; a notice board assembly for supporting notices or a chalk board or the like; a stage assembly for theatrical productions; symbol display assemblies, as for displaying the alphabet in block letters; and desk assemblies with adjustably high desk tops. In some embodiments of the present invention, the furniture base is not just a unitary component but an assembly of modules. Accordingly, there are modules which can be releasably coupled together to build a modular assembly of a furniture base. The modular base assembly, in turn, can be releasably coupled with several different auxiliary components to build a variety of assemblies including chair assemblies, desk assemblies, drawing board assemblies, sofa assemblies, and bed assemblies.
Some shortcomings of the prior art relate to the safety of the assemblies. For example, prior art assemblies may have sharp corners which may present a hazard to small children.
SUMMARY OF THE INVENTION
The present invention seeks to provide a modular furniture system utilizing a relatively small number of elements to construct various pieces of furniture, such as but not limited to, chairs, work tables, screens, blackboards and the like, by joining the relatively small number of construction pieces together in different manners, as is described in detail further hereinbelow. The present invention addresses the problem of safety and provides rounded corners and soft outer materials to provide maximum safety for even small children.
The present invention has advantages over the prior art due to several features. For example, as far as design and quality are concerned, the materials, dimensions and colors are chosen carefully to fit children's requirements and to have a long service life. The modular system affords unlimited assembly options to fit any space and need. The assembly may be remodeled to match children's growth. The system is washable and user friendly, requiring no screws for assembly.
There is thus provided in accordance with an embodiment of the present invention a modular furniture system including a plurality of generally, straight elongate bars, a plurality of connectors for connecting the bars to one another, the connectors including rounded, non-sharp corners and being constructed of an elastomeric material, and a plurality of furniture accessories adapted for connecting to at least one of the bars and connectors.
The furniture system may include one or more of the following features. For example, each of the connectors may include a six-sided polyhedron body with connector arms extending perpendicularly outwards from the polyhedron body. Each of the connector arms may have one or more peripheral grooves formed therein, and each of the elongate bars may include one or more internal teeth which fixedly sit in the one or more peripheral grooves when the connector arm is inserted in the elongate bar.
In accordance with an embodiment of the present invention, the furniture accessories may include a black board panel, a magnetic panel, a marker board, a mirror board, a basketball board, a compartment for storing recording media, a compartment for storing stationery, a storage box, a set of drawers, a book end, a shelf unit, and/or a cushion or any combination thereof.
