Description

  The present invention relates to an improvement of a mat used on a bed or the like as bedding, and more particularly, to a mat for bedding that has high heat retention, good ventilation, and less burden on the body due to use. It is.

  As is well known, daily sleep is very important for maintaining health, and in recent years, various functions are also required for mats used in bed as bedding. In other words, it has a heat retention property that prevents the body from cooling during sleep.

  A second required function is that the mat has air permeability. If this air permeability is not present, it will be steamed by moisture such as sweat from the body, causing discomfort and hindering deep sleep. In addition, as for the air permeability, those having an air-permeable structure due to unevenness on the surface and those having an air-permeability in the casing material itself are known (for example, see Patent Document 1).

  The third required function is that the mat has an appropriate rigidity, and if it is made of an excessively soft material (such as a sponge-like porous foam member) (for example, see Patent Document 2), Sometimes the body sinks into the mat under its own weight and is fixed in an unreasonable posture, which may hurt the waist and induce back pain. In addition, some mats have springs embedded with elastic repulsion, but the place where the springs are placed is hard and the pressure tends to concentrate, and there is a risk that the local area of the body will become congested. It was.

  Further, as described in Patent Document 1 or 2, some of the mats have corrugated irregularities formed on the surface of the mat, but these irregularities are crushed by the elastic deformation of the mat by the user's own weight. As a result, the groove portion is blocked, and there is a problem that sufficient air permeability cannot be secured.

However, if the groove is too large to ensure air permeability, there is a problem that the contact area of the body becomes small and the sleeping comfort becomes worse, and sufficient heat retaining properties cannot be obtained.

  According to the mat of the present invention, since it is formed of a continuously foamed plastic material, it has excellent heat retention and can effectively prevent a decrease in body temperature during sleep. It promotes blood circulation in surrounding tissues and is effective in preventing and improving coldness. Moreover, since heat retention is good, a heating appliance etc. become unnecessary and it can contribute to energy saving.

  In addition, since the mat has an appropriate rigidity, the body does not sink too much, it can maintain the most natural good posture, there is little effect on the joints such as the waist, and sleeping and low back pain are prevented. There is no risk of waking up.

  Furthermore, the rigidity of the plate body, the width of the ventilation groove, and the width of the ventilation groove are provided on the sleeping surface of at least one of the plate body by providing a ventilation groove having a required width and depth that allows ventilation even when the surface is elastically deformed by a load. Even if the depth is combined and elastically deformed by the user's own weight, the ventilation groove is not blocked, and good air permeability can be ensured.

  Furthermore, since the mat of the present invention can be formed by agglomerating foam beads and hot pressing, it can be manufactured at a very low cost by a simple process.

  Furthermore, by compressing and molding the foamed plastic material, it has a relatively high density while combining moderate spring elasticity and flexibility, so that it has water repellency on the surface and a closed cell structure. Since dirt does not penetrate into the interior, it can be actively used as a care product and the like, so it can be said that its practical utility value as a mat for bedding is very high.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described in more detail with reference to the drawings specifically shown as follows.

  An embodiment of the present invention will be described with reference to FIGS. In the drawing, what is indicated by reference numeral 1 is a mat body of a mat, and this board body 1 is a rectangular plate body made of a continuously foamed plastic material, and at least one sleeping surface of the board body 1 is ventilated. A groove 11 is provided (see FIG. 1).

  In this embodiment, polyethylene foam is used as the open-cell plastic material, and the ventilation groove 11 is provided at a required width and depth that allows ventilation even when the surface is elastically deformed by a load.

  Furthermore, in the present embodiment, the shape of the ventilation grooves 11 of the plate body 1 is made a rhombus or a quadrangular lattice, and the ventilation grooves 11 are provided on both surfaces of the plate body 1. The ventilation groove 11 can form a rhombus or a lattice by intersecting a plurality of parallel linear groove groups with each other.

  In this embodiment, by making the shape of the ventilation groove 11 of the plate body 1 into a rhombus or a quadrangular lattice, the loading pressure can be appropriately dispersed, and preferably, a plurality of parallel linear groove groups are arranged together.
