Description

[Detailed explanation of the idea] This invention relates to a new tatami mat.

Traditional tatami mats use a board-shaped tatami floor made by layering straw and sewing it together. However, when these tatami mats are laid on the second floor, for example, the noise from the stereo on the second floor can easily be transmitted to the first floor, and the movement of people can cause the floorboards to vibrate, causing squeaks. .

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this invention is a tatami mat that has excellent sound absorption, sound insulation, and vibration isolation properties.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. As shown in Figure 1, the tatami of this invention has the first layer from the top made of leather 1, for example, a plastic layer laminated on the surface of the fabric, and the second layer made of vegetable fiber such as Homogentex (trademark). The third layer is a sound-insulating soft or semi-rigid fiber board 2 of a required thickness formed with a special bonding agent, and the third layer is a perforated sound-absorbing board 3.
Then, the upper surface of the tatami floor 4, in which these three layers are bonded with adhesive, is covered with a tatami cover 5 made of rush,
The four sides are bordered with tatami edges 6 (see details in Figure 3) made of leather or the like, and anti-vibration rubber pieces 7 and suction cups 8 (see details in Figure 2) are fixed to key points such as the corners of the bottom surface. It is.

The tatami mat is fixed mechanically by means of a U-shaped clasp 9 along the folded edge on the tatami face 5 and a U-shaped clasp 9' extending over the edge on the lower surface of the tatami floor 4. be done. Note that this tatami mat may not have the suction cup 8.

The vibration-proofing rubber piece 7 has notches 10 formed on its lower surface. In addition to the rubber pieces 7, other cushion materials such as soft synthetic resin or porous material of the same shape can also be used for this tatami mat.

The tatami according to this invention has the above-mentioned structure, and when used, when spread on a designated floorboard, it is stabilized by the anti-vibration rubber pieces and suction cups on the bottom and absorbs impact force. However, sound can be insulated and absorbed by the sound-absorbing board and the fiberboard, and it is particularly useful for the second or higher floors of a multi-story building.

As mentioned above, the tatami of this invention can be manufactured mechanically at low cost in a tatami factory, for example, by assembly line work, and when used, especially when laid on the second or higher floors of a multi-story building, Noises in the room are insulated and absorbed, making it difficult for them to be transmitted to the rooms downstairs.Furthermore, the vibrations caused by people's movements are absorbed by cushioning pieces such as rubber, making it difficult to make floorboard squeaks. It has the advantage of being quieter than the conventional tatami mats used.
