A LEG AND BEAM BASED SYSTEM AND METHOD OF

ASSEMBLING

FIELD OF THE INVENTION The invention relates to furniture system. More particularly relates to Leg & beam based device, which provides flexibility to the furniture so that the same set of components used in the furniture are capable of configuring various furniture configurations.

BACKGROUND OF THE INVENTION AND PRIOR ARTS Prior Arts:

* Presently office furniture systems typically consists of panels of various heights and widths which are joined together to create partitions and work surfaces are supported on brackets which are usually hooked onto the vertical members of the frame. Other accessories are normally hung from the partition, panels, wires are passed through the hollow spaces within the vertical members.

*In other type of office furniture systems, desks are made using table tops and suitable understructure. Privacy screens are then mounted on top of the tables to provide privacy. These systems generally lack the wire management capability and have restriction on how high the privacy screens are provided. It also limits the usability as variety of finishes on privacy screens is limited.

*Third type of office partition system consists of poles which are joined together using panels and tabletops are hung on the poles using brackets. Normally external wire carriers are mounted on top of the panel providing limited wire management.

All the above systems have limitation in offering different layouts/configurations to suit various applications. Starting a module perpendicular to a panel from a place where there is no joint is virtually impossible and very limiting when space layout demands such flexibility.

This beam based device has mainly 4 parts to construct the structure.

Beam (Referring to figures 1 and 2) Beam is an aluminum extrusion, which can be cut to any desired length. Holes can be drilled at all faces of the beam to fix nut-rivets (Rivets with a tapping inside it) by riveting. These nut-rivets are fixed to the beam to connect different parts to the beam by means of screws. All the beams are used horizontally and run through entire configuration.

Beam section is designed in such a way that it forms channels on all four sides of the beam, one channel in top side, one channel in bottom side, two channels on left side, and two channels on Right side.

Inline Connector (referring to figures 18 to 21)

Inline connector is an aluminum extrusion. The cross section of this extrusion is designed in such a way that it can be screwed to other parts (i.e. Beam & Straight Leg).

The extrusion can be machined to have tapped holes so that it can be inserted into the hollow part of the beam and then the beam can be fixed to it by screwing. Inline connector is used to join beam to beam perpendicular to each other as well as beam to Straight Leg:

Straight Leg (referring to figure 15)

Straight leg is an aluminum extrusion which can be cut to a desired length. Tapped holes are provided to connect the post to inline connector and then the inline connector is fixed with the beam by means of screws (as shows in figures 15 to 17).

Leg (referring to figures 4 to 6)

Leg is made up of 5 components,

Top Connector,

Bottom Connector

Top aluminium Extrusion Bottom aluminium Extrusion

Leveler

Top connector is screwed at one end to Aluminum extrusion top and screwed at other end to Aluminum extrusion bottom, the other ends of both Aluminum extrusions are screwed to two prongs of Bottom Connector. A Plastic leveler is connected to bottom of Bottom connector for level adjustment. This leg can be connected to directly to the beam by means of screws. By using these four parts different configuration for workstations, conference tables and free standing tables can be made.

Inline connector (referring to figures 18 & 19)

The Inline connector which can be screwed to the main beam. The inline connector is then inserted into the hollow portion of the beam and then both are screwed together so that both beams can be connected perpendicular to each other to start another run of beam. This assembly can be done at any point on the main beam provided that the tapped holes are drilled at that point on the main beam.

Wire management in the furniture system (referring to figures 22 to 26) Wire management consists of following parts. 1) Horizontal wire carrier, 2) Horizontal wire carrier assembly with a plastic clip

3) Vertical wire carrier

4) Vertical wire carrier cover

5) Raceway brackets 6) Raceway connector

The raceway brackets are fixed to the beams by means of screws. The lower part of raceway bracket is connected to horizontal wire carriers. Then the adjacent horizontal wire carriers are connected to the beams in same manner. Now, horizontal wire carriers adjacent to each other are connected by raceway connector screwing it to both horizontal wire carriers. The vertical wire carriers are connected to horizontal wire carriers by same raceway connector. After these assemblies, the electrical and data/voice wires can be laid in the horizontal and vertical wire carriers. The vertical wire carrier cover is then screwed to vertical wire carrier and horizontal wire carrier cover assembly is hooked to the wire carrier by means of plastic cap.

Flexibility: Existing system has its rigid/fixed looks and features. For example, panel based systems are thick, heavy and closed, Desk and pole based system are weak, open, and having limited privacy. It is difficult to configure furniture for applications like meeting room tables or conference room tables or reception module and free standing table etc. which form an essential part of any typical office. The proposed system takes care of all the above areas and helps in retaining a uniform visual appeal throughout the office as shown in figures 27 to 28.

Storages: Most of the systems do not integrate storages and leave those to be kept on floor as independent units. It makes the spaces around and below these units difficult to clean and maintain. Also storage kept on floor require person accessing the bottom shelves to bend/lean a lot which is not ergronomical. For fixing the storages, two different beams are used at two different levels. These are screwed between the legs and straight legs one below the other.

Assembly of storage cantilever bracket is screwed to both the beams and storages are just placed and bolted with the storage cantilever brackets. The storage hook, which is fixed on the sides of the storage, hooked to the beam to prevent leaning of storages.
