Description:
A COMPOSITE FURNITURE SECTION

FIELD

The present disclosure relates to the field of frame structures. BACKGROUND Conventional frames, typically frames of doors and windows, are made by joining multiple vertical and horizontal components together. The conventional frames are fitted within a cavity formed in a structure, typically a wall, by means of fasteners such as screws. These frames are typically made of wood, or medium density fiber (MDF), or polyvinyl chloride (PVC) or any other similar material. However, all such frames have drawbacks, e.g., wood or medium density fiber frames absorb moisture and water, and have a swelling tendency. Further, any decorative surface provided on such frames delaminates due to absorption of water and moisture. The polyvinyl chloride (PVC) frames lack aesthetics, and strength to bear the load of a wooden door. Furthermore, these materials tend to warp along the length of the frame sections. Therefore, there is felt a need for a frame that alleviates the aforementioned drawbacks of the conventional frames.

100 - Composite furniture section 110 - Substrate layer 120 - Core layer 130 - Rebate layer 130A - Rebate surface 140 - Top layer DETAILED DESCRIPTION

The present disclosure envisages a composite furniture section that can be used in making of furniture. The composite furniture section, as envisaged in the present disclosure, in which moisture absorption is minimum, which results in a longer adhesion of the decorative surface on the furniture section. Further, the composite furniture section, of the present disclosure, has minimum warping tendency.

A composite furniture section 100, of the present disclosure, is now described with reference to figure 1A and figure IB. The composite furniture section 100 (hereinafter referred to as section 100) comprises a substrate layer (110) having a first operative surface and a second operative surface. A core layer (120) is disposed on the first operative surface of the substrate layer (110). A rebate layer (130) is disposed on the core layer (120). A top layer (140) is disposed on the rebate layer such that the top layer (140) partially covers the rebate layer (130) to define a rebate surface (130A) on the rebate layer (130). The rebate surface (130A) is the surface of the section (100) that abuts with the door supported on a door frame.

In an embodiment, the core substrate layer (110), the core layer (120), the rebate layer (130), and the top layer (140) are adhered to each other via a bonding agent. In an embodiment, after applying the bonding agent, the core substrate layer (110), the core layer (120), the rebate layer (130), and the top layer (140) are pressed upto a pressure of 50kg/cm for a period of upto 24 hours. Subsequent to the pressing operation, the edges of the section 100 are edge bound. In an embodiment, the decorative edge bands can be of any decorative material. Furthermore, in another embodiment, an ornamental layer is provided on the top layer (140), the rebate layer (130), and at least one edge of composite furniture section (100), wherein the ornamental layer of any decorative material. The ornamental layer can also include a dec- paint or digital printing as well. The ornamental layers are applied at all the locations of the section (100) which will be externally visible. Further, the bonding agent is used for edge banding of the composite furniture section (100). The bonding agent does not weaken the edge banding when heated or melted. Further, the bonding agent is moisture resistant and also difficult to detach once bonded.

In an embodiment, the substrate layer (110) is at least one selected from a group consisting of plywood, medium density fiberboard, high density fiberboard, particle board, composite wood, solid wood, block-board, imitation wood, and Wood Polymer composite (WPC).
