Description

[Detailed description of the invention] The present invention relates to a panel containing a filler material, and includes a frame body 1 with openings on both sides, face materials 2 attached to both sides of the frame body 10,
2 form a panel main body 3, and a band-shaped filler material 4 wound in a housing-like manner is arranged in a space within the frame body 1, and the outer surface is formed by the frame body 1.
This relates to a panel containing a filler material, in which the bell-shaped side edge of the filler material 4, which is in elastic contact with the inner surface of the filler material 4 or the outer surface of another filler material 4, is in contact with the face material 2.

Conventionally, as a filler disposed within the frame 1 of the panel main body 3, six arcuate cores 5 as shown in FIG. 1 have been used.

In other words, two spaces are created within the frame 1, and six spaces are created within the space.
Two cores 5 were placed back to back.

However, the 6-core 5 itself lacks strength, and the panel body 3
When force is applied to the 0 surface, the surface material 2 and the side edge of the 6-core 5 contact each other in a small area, causing the surface material to become dented, and when this panel is struck, the sound quality is poor. there were.

The present invention has been proposed in view of the following two points: The filling material is formed from an inexpensive material to improve the strength of the panel, and the filling material is intended to improve the sound quality. The company provides wood-filled panels.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral 3 in the figure is a panel body composed of a frame 1 and two face members 2, 2.

The frame 1 is open on both sides, has a predetermined thickness, has a space inside, and is framed in a square shape with square rods around the periphery.

At the center of the frame body 1, the interior is divided into two by a horizontal bar 6 to form two spaces.

Reference numeral 4 denotes a strip-shaped elastic filler made of cardboard or synthetic resin, for example, and the width l of the filler 4 is the same as the thickness of the frame 1.

Moreover, the number of turns of the filler 4 is also increased. However, the frame 1 is made by winding a spiral-shaped filler 4 and bonding one side with the face material 2.
When the filling material 4 is disposed in the space and the hand is released from the filling material 4, the wound filling material 4 returns to its original state.

That is, the size of the filling material 4 which had become smaller due to winding becomes larger due to the return force, and the outer surface of the filler material 4 comes into elastic contact with the inner surface of the frame body 1 and the side surface of the horizontal beam 6, as shown in FIG. is fixed within the space of the frame 1.

Next, the face material 2 is adhered to the opening surface of the frame body 1, and the process is completed.

On the other hand, the flexible side edges of the filling material 4 are in contact with the inner surfaces of the double-faced materials 2, 2, respectively, and will not be dented even if the facing material 2 is pressed from the outside.

As mentioned above, in the present invention, the panel body is formed by a frame with openings on both sides and face materials attached to both sides of the frame, and the filling material, which is wound in a band-like manner, is placed inside the frame. Since it is arranged in a space, just by winding the filler material, pressing the button in the space inside the frame body, and releasing the hand, the filler material can be naturally placed all over the space inside the frame body by the return force of the filler material. Moreover, since the outer surface is in elastic contact with the inner surface of the frame or the outer surface of another filler, the filler is securely fixed in the space within the frame, and the spiral-shaped side edges of the filler are securely fixed. Since it is in contact with a new material, it will not dent even when pressed from the outside, improving the strength of the panel, and improving the sound quality when the panel is struck. Moreover, it can be made using inexpensive materials such as cardboard or synthetic resin. It has the advantage of requiring only
