Description

  The present invention relates to cushions used as cushions, pillows, mattresses, mattresses, etc. used in seats of floors, chairs, wheelchairs and vehicles, ships, etc. It is related with the cushion which prevents a user's body from slipping on a cushion and having water repellency.

  In general, a cushion is manufactured by covering a cushion material formed by molding fiber, urethane foam or the like with a cover. Examples of the cover include those produced using a cloth such as a nonwoven fabric and those produced from a sheet material made of polyvinyl chloride resin.

  However, the cushion having the cloth cover has a problem in that moisture and dirt penetrate into the cushion when it gets wet or gets dirty. For this reason, for example, if an elderly person or an infant is incontinence while using the cushion on the buttocks or waist while sleeping, or if food or beverages are spilled on the cushion during a meal, care may be taken. It was very complicated and unsanitary.

  Therefore, a cushion having a cloth cover having a water-repellent finish on the surface has been proposed so that moisture does not easily enter the cushion. However, the water-repellent fabric cover has a decreased water repellency as washing and cleaning are repeated, and the initial water-repellent effect cannot be continuously obtained.

  On the other hand, the cushion covered with a cover made of a sheet material of polyvinyl chloride resin has the water repellency, so even if it gets wet or gets dirty, it can be easily cleaned and cleaned. Better than a cushion covered with a cloth cover. However, the cover made of polyvinyl chloride resin is very slippery, and the cushion can easily move from its normal position during use, or the user's body slides on the cushion and the use position is not stable. There was a problem. In particular, in the case of using it as a cushion on the seat surface of a wheelchair, there is a risk that the buttock slides on the seat surface and falls from the wheelchair when the user is seated or moved. In addition, since the cover made of vinyl chloride resin becomes more slippery when wet, it is particularly dangerous when moving outdoors in a wheelchair during rainy weather, for example.

  In addition, the cover made of polyvinyl chloride resin has a problem that durability is low, the plasticizer is eluted due to aging, and the eluted plasticizer causes deterioration of the cushioning material.

  Therefore, the present invention does not easily move the cushion from the normal position, does not slip on the cushion, and can be easily maintained even when wet or dirty. It is an object of the present invention to provide a cushion that can maintain cleanliness and is excellent in durability.

  In order to solve the above-mentioned problem, the means of the invention described in claim 1 is a cushion 100 including a cushion material 10 and a cover 20 covering the cushion material 10, and the cover 20 has an olefin on the surface. The cushion 100 is characterized in that it has a foamed sheet 30 made of a resin and the foamed sheet 30 has an uneven surface 33 formed thereon.

  By forming the surface of the cover 20 covering the cushion material 10 from the foamed sheet 30 made of an olefin-based resin having the uneven surface 32, the cover 20 can be provided with water repellency and anti-slip functions.

  By providing the cover 20 with water repellency, even when the cover 20 is wet or dirty, water and dirt do not penetrate into the cushion 100, so that the care can be easily performed. The cushion 100 can be kept clean. Further, by providing an excellent anti-slip function, it is possible to prevent the cushion 100 from being easily moved from the normal position and the user's body from sliding on the cushion 100.

  Furthermore, even after repeated washing and cleaning, the water repellency and anti-slip function are not deteriorated and the durability is excellent. Therefore, it can be used for a long time while maintaining the initial effect.

  In addition, the “cushion” in the present invention refers to cushions used as a pillow, mattress, mattress, etc. in addition to a cushion, which is used when sitting on a floor, chair, wheelchair or vehicle seat. .

  Moreover, the means taken by the device described in claim 2 is the cushion 100 according to claim 1, wherein the foam sheet 30 is antibacterial processed.

  By applying antibacterial processing to the foamed sheet 30, it is possible to suppress the propagation of germs on the surface of the cover 20, so that it can be kept clean.

  According to the cushion of claim 1, the surface of the cover that covers the cushion material is formed from the foamed sheet of the olefin resin, and an uneven surface is formed on the foamed sheet, thereby providing an excellent anti-slip effect. . Accordingly, the cushion does not move from the normal position during use, and the user does not slide on the cushion, and can be used at a stable position.

  In addition, because it has water repellency, even if the surface of the cushion gets wet or gets dirty, it can be cleaned by simply wiping it, and moisture and dirt will not penetrate into the cushion. The cushion material is not damaged and is hygienic. Furthermore, since the cover is made of a foamed sheet, it has excellent durability and can be used over a long period of time while maintaining the initial anti-slip effect even after repeated washing or cleaning.

  According to the cushion according to claim 2, in addition to the effect of the cushion according to claim 1, since the antibacterial processing is applied to the cushion cover, it is possible to prevent germs from breeding on the cushion surface, It can be used in a cleaner state.

  The present invention is a cushion comprising a cushion material and a cover covering the cushion material, and has a foamed sheet of olefin resin on the surface of the cover, and an uneven surface is formed on the surface of the foamed sheet. It is a characteristic cushion.

  The shape, size, etc. of the cushion according to the present invention are not particularly limited, and can be set according to the application. For example, if it is used as a cushion, it can be formed into a square, circle, or donut shape according to the area and shape of the seating surface of the chair. It can be formed into a shape or the like.

  The cushion material is not particularly limited, and a known cushion material can be used. For example, synthetic fibers such as polyester, polyamide, acrylic, polypropylene, and polyethylene, natural fibers such as wool, cotton, and linen, or resin foams such as urethane formed into a predetermined shape can be used.

  The cover covers the cushion material and is formed with a foamed sheet of olefin resin on the surface. By providing a foamed sheet of olefin resin on the surface of the cover, the cover can be provided with water repellency and can have an excellent anti-slip function. Examples of the olefin resin forming the foamed sheet include polyethylene, polypropylene, ethylene vinyl acetate, and the like. As a form of the cover, it is formed in a bag shape having an opening, a cushion material is stored in the bag from the opening, and the opening is sealed with a fastener and covered, or an endless or endless belt shape However, the form is not particularly limited as long as the cushion material can be covered.

  Moreover, an uneven surface is formed on the surface of the foam sheet. By forming an uneven surface on the surface, the adhesion of the surface of the cover is increased, and a more excellent anti-slip function can be achieved. The concavo-convex surface can be formed using a known technique such as forming by embossing a figure, a pattern, a character, or the like when foaming and molding the olefin resin into a sheet.

  Furthermore, the foam sheet may be subjected to antibacterial processing. By applying antibacterial processing to the foamed sheet, it is possible to suppress the propagation of germs such as staphylococci and Escherichia coli on the surface of the cover, so that a cushion superior in terms of hygiene can be obtained. As an antibacterial processing method, for example, a known antibacterial agent such as a metal ion antibacterial agent such as silver, zinc or copper or an organic antibacterial agent such as organic silicon or chitosan is mixed with the olefin resin raw material in advance. These may be foam-molded into a sheet, or coated with an antibacterial agent on the surface of the foamed sheet after molding.
