Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to unit tatami mats, which can be used by laying them in a part of a Western-style room, kitchen, or verandah as needed, and can be folded and stored when not needed. The present invention relates to unit tatami mats that are lightweight and have excellent heat retention properties and are effective for use as furniture-like tatami mats that can be used as furniture, or as tatami mats for mobile houses, prefabricated houses, bungalows, etc.

(Prior art) Most of the tatami mats commonly used in the past have used straw for the tatami floor. It is known for its insulated fiber board sandwiches and tatami floors. The size of tatami mats using these tatami floors is approximately J-shaku (length) and G (width) by 2-shaku (width).

(Problem that the invention aims to solve) As mentioned above, conventional tatami mats mainly use straw as the material for the tatami floor, and some tatami mats use foamed polystyrene as a sandwich. In any case, its size is 2 x t x g, and it is heavy. Therefore, when such conventional tatami mats are used for temporary buildings such as mobile simple houses or prefabricated houses at construction sites, transportation and storage are very troublesome.

In addition, conventional tatami mats are too heavy to be laid out in a Western-style room or verandah as a place to rest, and there are also difficulties in storing them when not in use.

When the above-mentioned medicinal wood tatami were applied to buildings in humid areas, such as mountain huts and bungalows, there were cases where the floor would rot or mold would develop due to the humidity.

In order to eliminate the defects of the conventional tatami mats using medicinal wood, the applicant has filed an application for registration of a utility model for simple tatami mats. For example, Jitsugan Showa 6o-t, 1yoz issue, Jitsugan Showa 6O-1s/910
There are numbers etc.

Although these simple tatami mats are lightweight, moisture resistant, and mold resistant, they are superior in many respects, but the corners of the tatami floor cannot be sharpened, and it is difficult to place particularly heavy objects on the corners of the tatami floor. Or, if a heavy person steps on the corner, that part may cave in,
It could get damaged.

Furthermore, some of these simple tatami mats are made by sandwiching both sides of foamed styrene with plywood boards in order to prevent warping of the tatami floor and sharpen the corners, but they are heavy and difficult to carry.

Instead of such plywood, a lightweight and strong honeycomb-shaped plastic laminate using tatami mats sandwiched on both sides of the tic foam is lighter and more effective than tatami mats using plywood etc. However, in subsequent improvement research, the honeycomb-shaped plastic laminate located on the back side of the tatami floor, among the honeycomb-shaped plastic laminates bonded to both sides of the foamed plastic foam, was registered as a utility model. As a result of using a plate different from the one on the surface, that is, a laminate of heat-sealed plastic sheets on one side of the core material, which is a plastic sheet with multiple cylindrical embossments, there are multiple cylindrical embossments between the plate and the floor. It was discovered that this creates air holes and prevents sweat from accumulating on the floor.

By attaching an inverted-shaped or U-shaped protector to the entire side corner of the tatami floor to which these honeycomb-shaped plastic laminates are bonded, it is lightweight and has dimensional accuracy, as well as the edges of the tatami floor. The present invention was achieved by successfully obtaining a unit tatami mat that can be used as furniture with excellent strength.

(Means for solving the problem) That is, the present invention provides a central substrate 2 made of foamed plastic foam or insulated fiberboard.
In a unit tatami mat, a tatami face is placed on a tatami floor 1 with honeycomb-shaped plastic laminates 3 and 4 bonded to both sides of the tatami mat, and the tatami face is sewn together with a hem cloth. A laminate is used in which plastic sheets 22 and 23 are heat-sealed to both sides of a core material 21 that has been subjected to cylindrical embossing 20, and a plurality of cylindrical embossments are further applied to the plastic sheet as a honeycomb-shaped plastic laminate 4. A laminate plate with a plastic sheet 21 heat-sealed to one side of the core material 20 is used, and an inverted-shaped protector 5 or a U-shaped protector 6 is attached to the side corner of the tatami floor 1. Regarding unit tatami mats featuring
Furthermore, in the present invention, the honeycomb-shaped plastic laminate 4
It is preferable to cover the core material 2 (l) which has been subjected to a plurality of cylindrical embossing by joining the cross sheet 12 to the back surface of the core material 2 (l).

In order to prevent ti unit tatami mats from slipping when laid on wood, plastic tiles, etc., it is effective to attach a non-slip material such as plastic or rubber to the back of the unit tatami mats.

Furthermore, by attaching Velcro tape 13 to the back side of the unit tatami mats, it is possible to connect a plurality of unit tatami mats.

The present invention will be specifically described below based on embodiments shown in the drawings.
