が発生し著しく外観を損うという不都合がある。Technical background of the invention and its problems In general, a kotatsu board 1 as shown in Fig. 1 is used by placing a futon on top of a yagura. Decorative board 3 such as a thermosetting resin board is placed on the surface of the core material 2 such as
are pasted together and surrounded by an outer frame 4. However, in this case, as mentioned above, since a heavy homogen board (particle board) or the like is used as the core material 2, the weight of the kotatsu board 1 is approximately 8 kg to 12 kg, which has the drawback of being difficult to handle. be. For this purpose, a foamed resin or the like is used for the core material 2, a reinforcing frame 5 is provided on its outer periphery as shown in FIG. A device that fits into a groove 6 formed on the circumferential surface has also been proposed. However, in the above-mentioned kotatsu board, the depth of the groove 6 of the outer frame 4 is shallower than the width of the reinforcing frame 5, and the inner peripheral edge of the reinforcing frame 5 is located inward than the inner peripheral edge of the outer frame 4. Therefore, if force is applied to the center of the kotatsu board 1, the top surface will curve downward, causing the decorative board 3 on the top surface to bend.
is bent at the upper inner peripheral edge A of the reinforcing frame 6, and a line is generated at the boundary between the core material 2 and the reinforcing frame 5, resulting in a disadvantage that the appearance is significantly impaired.
考案の目的

徴とする。Summary of the invention This invention uses a foamed resin such as hard urethane for the core material, and the outer peripheral edge of the kotatsu board body, which is formed into a plate shape with a reinforcing frame and a decorative board, is formed on the inner peripheral surface of the outer frame.
The reinforcing frame is fitted into a groove having a depth equal to or slightly deeper than the width of the reinforcing frame, so that the boundary between the core and the reinforcing frame is not located outside the groove of the outer frame.
考案の実施例

上下両面に化粧板３，３を装着することによつて
こたつ板本体が形成され、このこたつ板本体の外
周に外枠４が装着されている。Embodiment of the invention FIG. 4 is a longitudinal side view showing an embodiment of the invention, in which a reinforcing frame 5 is attached to the outer periphery of a core material 2 made of a foamed resin such as hard urethane, and a decorative plate is attached to both the top and bottom surfaces of the core material 2. A kotatsu board main body is formed by attaching the kotatsu board 3, 3, and an outer frame 4 is attached to the outer periphery of this kotatsu board main body.
すなわち、上記外枠４の内周面には、こたつ板
本体の厚さと同じ高さで、かつ前記補強枠５の幅
Ａ以上の深さＢを有する凹溝６が形成されてお
り、この凹溝６に前記こたつ板本体の外周縁部が
嵌合せしめられている。 That is, a groove 6 is formed on the inner peripheral surface of the outer frame 4, and has a height equal to the thickness of the kotatsu board body and a depth B greater than the width A of the reinforcing frame 5. The outer peripheral edge of the kotatsu board body is fitted into the groove 6.
しかして、このように形成されたこたつ板の中
央部に力が加わつた場合、上面の化粧板３が下方
に彎曲するけれども、補強枠５の内周端縁が外枠
４の内周縁と同じ位置か或は凹溝６内に位置する
ため、上面側の化粧板３の外面に露出している部
分には折曲線が生ずることはなく、化粧板表面に
折曲によるラインが発生するようなことはない。 However, when a force is applied to the center of the kotatsu board formed in this way, the decorative board 3 on the top surface curves downward, but the inner peripheral edge of the reinforcing frame 5 is the same as the inner peripheral edge of the outer frame 4. Because it is located in the groove 6, there will be no bending lines on the exposed outer surface of the decorative board 3 on the top side, and there will be no lines due to bending on the surface of the decorative board. Never.

ことがない。Effects of the invention As explained above, according to the invention, since a foamed resin such as hard urethane is used for the core material, the weight of the kotatsu board is not reduced, and the outer peripheral edge of the kotatsu board body is fitted. The depth of the groove on the outer frame of
The width was the same as or deeper than the reinforcing frame, so
There are no lines caused by bending on the surface of the decorative board exposed to the outer surface, and the appearance is not impaired.
