Description

  The present invention relates to a tatami mat including a tatami floor portion and a tatami surface portion detachably covered thereon.

Traditionally, tatami mats are moderately elastic and hygroscopic, so they are widely used as traditional flooring materials in Japanese houses. Usually, tatami mats are woven tatami mats that are knitted with natural rushes for wefts and hemp yarns or cotton yarns for warp yarns, and dried rice straws are sewn with hemp yarns to a suitable thickness. The tatami surface covers the upper and side surfaces of the tatami floor and is sewn on the lower surface with hemp yarn or the like.
In recent years, tatami mats have been knitted with so-called imitation rushes made of thermoplastic resin instead of natural rushes, and feel and appearance are almost the same as those using natural rushes. In addition, it has excellent water resistance and durability. In recent years, tatami floors include those made of laminated wooden boards and cushioning materials and those made of synthetic resin foams, etc., which have excellent water resistance and are resistant to the growth of pests and molds such as mites. It is a typical one.
Examples of such tatami include those described in Patent Document 1. Patent Document 1 describes wrapping a tatami floor using rice straw with a waterproof breathable sheet made of a porous film and a protective cloth, and fixing the tatami surface to the tatami floor with a fixing means such as an adhesive tape or a hook-and-loop fastener. Has been. It is described that an adhesive tape or Velcro (registered trademark) is used as the fixing means.

However, the conventional tatami mat has the following problems.
(1) Even when using a knitted synthetic resin imitation rush as a tatami surface, if you spilled a drink or the like on the tatami surface during a meal, you could not remove it completely just by wiping it, In particular, in the case of urinary incontinence in a nursing home or the like, or when oil or juice of food dropped from a table adheres, there is a problem that dirt, stains, odors, etc. remain only by wiping, and lack hygiene.
(2) The urine and the like soaked from the thread at the sewing part, and even if the tatami mat is dried or the tatami mat surface is wiped, the thread at the sewing part is inside the tatami mat, so the odor of the urine soaked into the thread does not come off and uncomfortable Had the problem of giving.
(3) When tatami mats are sun-dried and sterilized, or when tatami mats are exchanged, it is necessary to transport the tatami mats. In the case of using a braided rice straw, the weight is heavy, and it cannot be easily carried and has a problem of lack of handling.
(4) In the tatami mat of Patent Document 1, simply fixing the tatami mat to the tatami floor may cause the tatami mat to be displaced or wrinkled with respect to the tatami floor, and the upper and side corners of the tatami mat may be easily rounded. In particular, when a fixing means having a relatively weak fixing force such as an adhesive tape or Velcro (registered trademark) is used, this tendency becomes remarkable and there is a problem that the appearance is lacking.
(5) When rice straw is used as a tatami floor as in Patent Document 1, the rice straw becomes a nutrient source for pests such as ticks, so that ticks propagate inside the tatami floor and are unsanitary. Have the problem of being unsanitary, causing allergies and causing diseases such as infants with weak resistance.

  The present invention solves the above-mentioned conventional problems, and can be removed from the tatami floor by washing, sun-drying, etc., and since there are no sewn parts, germs can be prevented from breeding inside the sewing thread and tatami floor. An object of the present invention is to provide a tatami mat that is excellent in hygiene and can be easily engaged with the tatami mat surface portion being stretched on the tatami floor portion, and that is excellent in appearance by preventing the occurrence of displacement and wrinkles. And
