【The invention's effect】
As described above, according to the present invention, as the base material of the top plate, the panel material having the core sandwiched between the upper plate and the lower plate made of light metal is used. It is possible to make a top plate that is extremely easy to handle and highly recyclable when the table is frequently changed in layout.
[0030]
Steps corresponding to the thicknesses of the upper and lower plates of the panel material are provided on the upper and lower surfaces of the frame that borders the periphery of the panel material, and the upper and lower edges of the upper plate are brought into contact with the stepped portion. Therefore, even if there are some manufacturing errors on the upper and lower plates, they can be assembled without any problem. Especially, the upper plate is concealed between the peripheral edge of the upper plate and the stepped portion by the decorative plate stuck on the upper plate. Therefore, it does not appear at all in appearance, and it can be a top plate with good appearance.
[0031]
Further, when attaching the decorative board, the peripheral edge of the excess decorative board protruding from the frame is trimmed along the frame to adjust the shape, so that the top shape of the top board is a deformed top board having a curved peripheral edge. However, it can be finished without causing an error between the decorative plate and the frame.
[0032]
Furthermore, since the outer periphery of the frame is edged by fitting resin edge material, the panel material and frame are not exposed, and the edge material is attached to the frame by fitting, so it is Separation is easy and collection by material can be easily performed.
[0033]
Further , if the gap P is provided between the outer end surface of the front frame and the inner end surface of the front edge material, it is possible to prevent the resin edge material from being deformed due to a temperature change. Further, since the cavity is formed inside the outer edge of the front edge material, a so-called “sink” does not occur on the surface of the edge material, and a well-shaped edge material can be obtained and the cavity By having a part, it contributes also to the reinforcement | strengthening of a lower side, and can raise the intensity | strength of the whole front edge material.
[0034]
Further, since the front edge material has a close edge at the front end position of the engagement piece, when the engagement piece is fitted into the engagement recess of the front frame, the front edge material closely contacts the edge of the decorative plate, and the front edge It is possible to prevent the top side of the material from being lifted and to obtain a top plate that does not lose its shape for a long time.
