S&F Ref: 973716 AUSTRALIA PATENTS ACT 1990 INNOVATION PATENT SPECIFICATION Name and Address Hirakawa Corporation, incorporated in Japan, of 1-13 of Applicant: 4, Nihonbashi-kakigara-cho, Chuo-ku, Tokyo, 103 0014, Japan Actual Inventor(s): Shoichi Hirakawa Address for Service: Spruson & Ferguson St Martins Tower Level 35 31 Market Street Sydney NSW 2000 (CCN 3710000177) Invention Title: Elastic human body cooling apparatus The following statement is a full description of this invention, including the best method of performing it known to me/us: 5843c(3127830_I) 1 ELASTIC HUMAN BODY COOLING APPARATUS Technical Field The present invention relates to an elastic human body cooling apparatus, and s particularly relates to an elastic human body cooling apparatus which, utilizing the cooling effect of a cooling medium containing gel, can be used for cooling each portion of a human body, and which has resilience and gas permeability, giving a good feeling upon use. 10 Background Art Conventionally, people has accommodated a cooling medium containing gel in an exterior element of a pillow size, a futon mattress size, a bed sheet size, or the like, to form a cooling pad, and at the time of sleeping, or the like, in the high temperature season, has used this cooling pad with a pillow for cooling the head, or placed it on the i5 bed for cooling the back, and the like, of the body. With such a cooling pad, the migratability of a cooling medium containing gel accommodated inside thereof is high, thus if the cooling medium is only accommodated in the exterior element, the weight of the body would cause the cooling medium to be unevenly distributed in the exterior element, resulting in a sufficient cooling effect for the 20 body being not capable of being expected. On the other hand, in recent years, cubic nets which are formed into a pillow size, a futon mattress size, a floor cushion size, or the like, being provided with resilience have been put into practice, and these have been used at the time of sleeping or in Japanese style rooms, and the like. 25 In the patent document 1, as an item related to the cooling pad, a cooling/heating gel pillow including a cooling/heating gel sheet of a pillow size, and a pillow cover having an accommodation part inside thereof into/from which this cooling/heating gel sheet can be inserted/removed is disclosed. However, it is a main object of the cooling/heating gel pillow as disclosed in the 30 patent document 1 to provide the cooling effect thereof for the head of human body, and the size thereof is relatively small, thus in consideration of the migratability of the water containing gel, it is estimated that, even if the configuration of such a cooling/heating gel pillow is applied, as it is, to a human body cooling apparatus of a long size, such as a bed sheet size, or the like, no sufficient cooling effect can be expected.
2 In the patent document 2, as an item related to the cubic net, there is proposed a cushioning material which connects between the front and back nettings, using connecting strings, for making a cubic item, thus allowing it to be used as a pillow, a mat, or the like. 5 However, at present, no elastic human body cooling apparatuses are available which combine the cooling effect of a cooling medium containing gel with a multi-hole elastic body assuring a moderate resilience and gas permeability, and having a good feeling upon use, and which can exert each of these functions. [Patent document 1] Japanese Patent Laid-Open Publication No. 2002-23442 10 [Patent document 2] Japanese Patent No. 4001890 In a variety of sizes such as a pillow size, a futon mattress size, a bed sheet size, and the like, no elastic human body cooling apparatus is available which can suppress uneven distribution of the cooling medium due to the migratability thereof and impart a sufficient cooling effect on the body, having a moderate resilience, a good gas is permeability, being excellent in heat dissipation capability, and giving a good feeling upon use.
