A PILLOW

Abstract: An improved pillow according to the invention is provided by inserting cushion material (3) fixed with a plurality of porcelain tiles (2) on its surface, into a bag body (1) having pearmeability and elasticity. Its shape is held during use, and natural sleeping posture is maintained, and the porcelain tile (2) cools the head moderately for comfort­ able sleep.

Description: A PILLOW BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates to an improved pillow for pleasant sleeping. DESCRIPTION OF THE PRIOR ART Sleeping is indispensably important for removing fatigue or tiredness. For having sound sleep, not only bedding but also pillow give large influence. "Keeping the head cool and the feet warm" has been told as a first condition to the comfortable sleep. This is righteous in view of the scientific aspect, too. One of the medical data reports that the mind is made stable and a man may go into natural sleeping by lowering the temperature in the pillow by about 5 to 100C than the temperature of the back of the head (around 350C). Further the size and height of the pillow is closely relative with the peaceful sleep. Thus, difference of more than 20 minutes arises until the deep sleep between the pillows suitable and not suitable to the sound sleep. Difference also occurs in clearness at waking up. Although the pillow gives the large influence to the sleep, there has not an ideal pillow taking into consideration so far. SUMMARY OF THE INVENTION A main object of the invention is to provide a pillow with which the sleep is naturally obtained. Another object of the invention is to provide a pillow which absorbs and exhausts the temperature at the back of the head, so that the condition of "keeping the head cool and the feet warm" is maintained during sleeping. A further object of the invention is to provide a pillow which has the most suitable height and hardness to the peaceful sleep, so that ideal sleeping posture may be obtained. Other objects and advantages to be brought about by the invention will be apparent from description of the invention with reference to the drawing. BRIEF DESCRIPTION OF THE DRAWING Fig. 1 is a perspective view, partially in section, showing a pillow according to the invention, taking out stuffed material, and Fig. 2 is a vertical cross sectional view showing inner structure. DETAILED DESCRIPTION OF THE INVENTION An improved pillow according to the invention is composed by inserting cushion material 3 having porcelain tiles on its surface into a bag body 1 made of urethane form. The bag body I is made of the cushion material, preferably urethane form, where wave-like projections 5 are formed regularly lengthwise and crosswise on the urethane form 4 of about 150mm in thickness, and resin liquid such as liquid of urethane form is impregnated thereon to form said bag of a hard outer cover 6. For the cushion material, thick urethane form is in gene ral employed, on a surface of which six, e.g., flat porcelain tiles 2 are fixed with adhesives, and spacers 7 are preferably arranged to stop movement of the tiles. For the spacer 7, plastic plates may be used which run lengthwise and crosswise on the spaces between the porcelain tiles 2, otherwise the urethane form pieces may be used which are hardened by impregnating resin liquid. Such spacers 7 are fixedly positioned on determined parts of the cushion material 3, and subsequently the porcelain tiles 2 are attached to the cushion material 3, or after having attached the porcelain tiles 2, the spacers 7 are positioned in place at the spaces between the tiles 2. The cushion material 3 having the tiles 2 is inserted into the bag body 1 and the bag body 1 is closed at its mouth. In use, the bag body 1 is protected with clothmade cover. The pillow according to the invention has the above said structure, and may advantages as follows. 1) Peaceful sleep of natural posture The combination of the concaves and convexes (wave like projection) and the porcelain tiles, keeps the shape of the pillow stable. Therefore the pillow little moves as conventionally, so that the comfortable sleep may be promised all night long. 2) Height for natural sleeping posture Being too high, muscles at the neck or the shoulders are stretched and stiffness occur there. Being too low, conversely, the neck is tense and the sleep is slight so that fatigue is not removed. The pillow by the invention makes the mind relaxed and is about 8cm in height. 3) Keeping the head cool and the feet warm by the porcelain tiles. 4) Hygienic by the air pearmeability and evaporation The pearmeable material such as the urethane form is used and formed with concaves and convexes due to the wave like projections. The shape is held and the pearmeability is maintained.

Claims: WHAT IS CLAIMED IS 1. An improved pillow, provided by inserting cushion material fixed with a plurality of porcelain tiles on it surface, into a bag body having pearmeability and elasticity. 2. A pillow as claimed in Claim 1, wherein the bag body is made of urethane form. 3. A pillow as claimed in Claim 2, wherein the bag body is made of urethane form where wave-like projections are formed regularly lengthwise and crosswise on the urethane form, and resin liquid such as liquid of urethane form is impregnated thereon to form said bag of a hard outer cover. 4. A pillow as claimed in Claim 1, wherein the cushion material is made of thick urethane form. 5. A pillow as claimed in Claim 5, wherein porcelain tiles are attached on the cushion material via spacers. 6. A pillow as claimed in Claim 5, wherein the spacer is plastic plate having a shape lying on each of spaces between the porcelain tiles. 7. A pillow as claimed in Claim 5, wherein the spacer is urethane form piece which is provided by hardening due to impregnation of resin liquid such as urethane form.
