Description

  The present invention relates to a plate-like body such as a furniture top plate, a side plate, a door, a partition, a partition or a wall panel, and a core material made of a hard foamed resin between a first outer surface material and a second outer surface material. And forming a groove-shaped notch in the hard foamed resin so that a hard end made of hard resin is brought into close contact with the side edge of the plate-shaped body and the groove-shaped notch. This is a technology relating to a plate-like body that is formed integrally and is lightweight and highly rigid.

2. Description of the Related Art Conventionally, plate-like bodies such as furniture top plates, side plates, doors, screens, partitions, and wall panels have various structures depending on the application.
For example, as a decorative panel designed to reduce weight, a paper core is used as a core material, a face plate is bonded to both sides of the core material, and an edge material is formed by casting a thermosetting resin at the end of the core. (For example, refer to Patent Document 1).

  In addition, as a furniture top plate that achieves both writing and shock absorption, a two-component urethane resin or a two-part urethane resin is used on the side edge of the top plate body in which a core material and a back material made of surface material, cushion material, particle board are laminated. A material in which a lip material made of a thermoplastic resin is in close contact is known (see, for example, Patent Document 2).
