Description

  The present invention relates to a bedding cover for adjusting the temperature of a three-dimensional network structure used for a mattress, a cushion, and the like.

  Due to global warming in recent years, it has become extremely hot, and measures against summer heat have been demanded, but are still not sufficient.

  As the cool bedding, for example, there are a type using a breathable material, a gel type, a type cooled with a chemical, and the like, and various types of products such as mattresses, cushions, and sheets are provided.

  Inventions for temperature adjustment using a three-dimensional network structure include the following.

  The so-called cool sensation product feels cold for a moment but warms up at body temperature, the cooling sensation effect is not maintained, and it cannot be applied to long-term use.

  The invention of Patent Document 1 has a complicated ventilation structure, insufficient cooling of the mat (7), a sense of incongruity for the user, an excessive amount of air and pressure, and noise. There was a problem that it could not stand the use of time.

  The invention of Patent Literature 2 has a problem that ventilation is hindered by the urethane foam layer, cannot be used for a long time, and washing and cleaning are complicated because the air duct is disposed inside.

  The invention of Patent Literature 3 has a problem in that ventilation is impeded by the urethane foam multi-layered layer, cooling is insufficient, and a large air supply source such as a blower that cannot withstand long-time use is required. I was

  The invention of Patent Literature 4 has a problem that ventilation is insufficient, cooling is insufficient, and it cannot be used for a long time, and a problem that air-conditioning piping is required to supply air from the air conditioner is present. I was

  The invention of Patent Literature 5 is a pressure ulcer prevention mattress having a gas-permeable epithelial cushion layer 13 on the coarse fluid layer 2 and a non-gas-permeable lower cushion layer 11 below the coarse fluid layer 2. However, there is a problem that the ventilation is insufficient, and it is difficult to use it in summer due to the circulating supply of warm air.

  Therefore, the present invention diffuses the air ventilated to the bedding to the whole of the bedding, enhances the air permeability, enables long-term use with an appropriate cooling sensation, and enables washing and cleaning of the three-dimensional net-like structure and the cover. It is an object to be easy and compact.

  The present invention relates to a fiber cover having an upper surface, a lower surface, and a side surface and having a fastener for accommodating a three-dimensional network structure on the side surface, and a bag-like or band-like pipe support provided inside the side surface provided with the fastener. And a pipe having one end and an L-shaped other end inserted into a longitudinal side face of the three-dimensional network structure, wherein the pipe is disposed in a longitudinal direction of the longitudinal side face of the side faces. It is a bedding cover characterized by being done.

  The three-dimensional network structure has a plurality of surfaces, for example, an upper surface, a lower surface, and four side surfaces, and a rectangular parallelepiped having side surfaces in a longitudinal direction and a lateral direction is exemplified. Of these, it is preferable to form two, three, or four, five, or more multi-faces, and it is preferable to form it into an irregular shape if necessary.

  The bedding cover is applied to covers for bedding, for example, mattresses, pillows and the like. Examples of the cover include inner and outer bedding.

  The other end of the L-shape is preferably an L-shaped nipple, and the material is exemplified by polypropylene.

  The fiber cover is preferably made of a material having high air permeability, and preferably has a three-dimensional structure mesh, that is, a so-called double Russell structure. For example, Kome Inc. product name light mesh, product number W-220, and 100% polyester material are exemplified.

  The pipe diameter of the pipe is preferably 3 to 12 mm (inner diameter). If the pipe diameter is smaller than 3 mm, the air volume becomes insufficient and the number of pipes increases, and if the pipe diameter is larger than 12 mm, it becomes difficult to insert the pipe into the space of the three-dimensional net-like structure 2 and to store it in the fiber cover 4. . The pipe may be singular or plural. In the case of a single pipe, the other end of the L-shape is provided at a different point of the pipe. When there are a plurality of pipes, the pipes are independently provided, and each of the pipes is provided with an L-shaped other end.

  Preferably, the bedding cover further includes a branch adapter, and a plurality of pipes having different lengths are provided, and one end of the pipe is preferably connected to the branch adapter. If a plurality of pipes are used, it is possible to avoid a decrease in pressure and air volume at the end rather than using a single pipe and branching the pipe from the middle of the pipe. The length of the pipe is exemplified by 20 to 200 cm.

  It is preferable that a hook-and-loop fastener for temporarily fixing the pipe or a fiber bag for housing the pipe is arranged on the back side of the long side face of the side faces along the longitudinal direction. In this case, the fiber bag is provided with a hole for projecting the other end of the L-shape.

  The fabric of the hook-and-loop fastener is a so-called pile type, for example, a French pile. For example, Bore Tape, a product name of Jack Corporation is exemplified. It may be made of nylon or polyester, which increases durability. The surface fastener has a width of 1.6 to 15 cm and a length of 20 to 200 cm, but is not limited thereto.

  The branch adapter is connected to an electromagnetic air pump. The electromagnetic air pump preferably has a flow rate of 32 to 200 L / min, a working pressure range of 5 to 25 kPa, a power consumption of 25 to 125 W, a discharge port diameter of 5 to 25 mm, and a mass of 4.4 to 6.1 kg. Since it is appropriately adopted according to the volume, it is not limited thereto. With an electromagnetic air pump, low cost and low noise can be realized.

  A pneumatic pressure gauge may not be provided, but may be provided to properly adjust the air pressure.

  It is preferable that a regulator for adjusting the amount of air supplied from the electromagnetic air pump be provided in the pipe.

  The bedding cover can use natural air that is not adjusted by the air conditioner, but can also use air that is adjusted by the air conditioner.

  The appropriate cooling sensation can be adjusted to, for example, a range of 2 ° C. above and below the human body temperature, so that an appropriate cooling sensation can be obtained.

  The temperature can be adjusted by increasing or decreasing the air volume of the electromagnetic air pump. Since the air volume is smaller than that of the air conditioner, it is not too cold. The electricity bill is also cheap.

  Since outside air or indoor air can be continuously supplied to the three-dimensional network structure through the piping, even if heat is accumulated at the contact portion between the fiber cover and the three-dimensional network structure and the human body at the temperature of the human body. Since the outside air or room air having a temperature lower than the temperature of the human body is diffused and supplied to the three-dimensional network, an appropriate cooling sensation can be obtained. Natural circulation of air in the fiber cover and the three-dimensional network structure is good for health.

  The bedding cover 1 according to the embodiment of the present invention will be described.

  As shown in FIGS. 1 to 8, the bedding cover 1 includes a fiber cover 4 having a fastener 3 for accommodating the three-dimensional net structure 2 on a side surface 4 e, and a belt-like shape provided inside the side surface 4 e provided with the fastener 3. , A branch adapter 7 connected to the electromagnetic air pump 6, one end portions 8 a to 8 c connected to the branch adapter 7, and an L-shaped plug inserted into a longitudinal side surface of the three-dimensional net structure 2. And a plurality of pipes 10a to 10c having different lengths and a pipe diameter (inner diameter) of 3 to 12 mm having the other end parts 9a to 9c. The pipes 10a to 10c and the pipe support 5 are arranged inside the side face 4e. The details will be described below.

The three-dimensional net-like structure 2 has a rectangular parallelepiped shape, and has an upper surface 2a, a lower surface 2b, two short side surfaces 2c and 2d, and two long side surfaces 2e and 2f. The dimensions of the three-dimensional net-like structure 2 are exemplified by 193 cm in length × 95 cm in width × 4.5 cm in thickness. The thickness is from 1 cm to 20 cm, in particular from 3 cm to 15 cm, particularly preferably from 4 to 10 cm. The bulk density of the three-dimensional network structure 2 0.01~0.94g / cm ^{3, preferably, 0.02g / cm 3 ~0.9g / cm} 3, particularly preferably, 0.025g / ^cm 3 ~0 0.2 g / cm ³ is exemplified, but is not limited to that range.

  Examples of the method for manufacturing the three-dimensional network structure 2 of the present embodiment include Japanese Patent Application Laid-Open No. 2001-328153, Japanese Patent No. 4350286, US Patent No. 7,625,629, and International Publication WO2012 / 157289. , So please refer to it. However, it is not limited to this manufacturing method.

  The material of the three-dimensional network structure 2 can be appropriately adopted. A structure in which three-dimensional network structures 2 of the same or different materials are stacked can also be applied.

  In the three-dimensional network structure 2 of the present invention, it is necessary to appropriately select a resin, a wire diameter, a loop diameter, a surface layer, a bulk density, and a shape to be used depending on the purpose of use and the site of use. For example, raw materials are selected at appropriate times according to the hardness preference in the country of use. When used as a layer, an appropriate bulk density is selected depending on whether it is a surface layer or an intermediate layer. Further, it can be formed into a shape suitable for the purpose of use using a molding die or the like to the extent that the three-dimensional structure is not impaired, and can be used for beddings such as mattresses. Of course, in order to meet the required performance, it is also possible to use multiple layers of the same material with the same structure and multiple layers of the same structure with a different material. This material can be processed so as to have a function of making it inflammable, non-combustible, antibacterial, and coloring. The removable fiber cover 4 can be appropriately designed with a material suitable for each of the air permeability and the waterproof performance.

  The fastener 3 is a general one and includes a slider 3a, an element 3b, and a tape 3c.

  The fiber cover 4 has a double Russell structure, has good air permeability, and has an upper surface 4a, a lower surface 4b, two short sides 4c, 4d, and two long sides 4e, 4f. The fiber cover 4 is a mattress inner. The fiber cover 4 is a light mesh of Kowa Co., Ltd., product number W-220, and the material is 100% polyester. The dimensions of the fiber cover 4 are, for example, 196 cm long × 98 cm wide × 5.5 cm thick, but are not limited thereto.

  The pipe support 5 is a plastic or fiber hook-and-loop fastener, and includes a strip 5a arranged in the longitudinal direction and a strip 5b arranged in the transverse direction. The strip 5b can be detached from the strip 5a. The belt-shaped portion 5a has a structure and a material that cause less adhesion of dirt during washing. The band portion 5a is sewn on the back surface of the side surface 4e to form a two-layer structure. Therefore, it is difficult for air to escape from the side surface 4e. The fabric of the hook-and-loop fastener of the band portion 5b is a so-called pile type, for example, a French pile. For example, Bore Tape, a product name of Jack Corporation is exemplified. If it is made of nylon or polyester, the durability will be high. The dimensions of the belt-like portion 5a of the pipe support 5 are exemplified by a width of 5.5 cm and a length of 193 cm, but are not limited thereto.

  The strip-shaped pipe support 5 for temporarily fixing the pipes 10a to 10c to the side surface 2e is a surface fastener. Instead, a fiber bag may be arranged to accommodate the piping. In this case, the fiber bag is provided with a hole for projecting the other end of the L-shape. Since the pipes 10a to 10c are sandwiched between the side surface 2e of the three-dimensional network structure 2 and the band portion 5a, they are not easily shifted.

  The pressure of the air supplied from the electromagnetic air pump 6 to the pipes 10a to 10c is preferably 1.3 to 2.5 atm. The power supply line is not shown.

  The electromagnetic air pump 6 has an air volume of 100 to 120 L / min, a working pressure of 5 to 25 kpa, a power consumption of 51 to 125 W, a discharge port diameter of 18 mm, and a mass of 6.1 kg.

  The branch adapter 7 has a plurality of branches, for example, a three-pronged structure. Tube joints are provided at the inlet and outlet of the branch adapter-7.

  The other ends 9a to 9c of the L-shape are L-shaped nipples, and are made of polypropylene. As the L-shaped other end portions 9a to 9c, Toyox L-type nipple 8 mm LN-08 is exemplified. The reduced-end ends of the other ends 9a to 9c can be inserted into and extracted from each of the pipes 10a to 10c, and are inserted into the gaps of the three-dimensional network structure 2 when used.

  The reason why a plurality of pipes 10a to 10c are used and the pipes are not branched off in the middle of one pipe is to avoid the pressure and the air volume from being reduced toward the tip end.

  The pipes 10a to 10c are arranged in the longitudinal direction of the longitudinal side face of the side face 2e of the three-dimensional network structure 2. The lengths of the pipes 10a to 10c in the fiber cover 4 are 158 cm for the pipe 10a, 95 cm for the pipe 10b, and 30 cm for the pipe 10c. The inner diameter and the outer diameter of the pipes 10a to 10c are 8 mm and 10 mm, but are not limited thereto.

  A fastener 11 is provided to bundle the pipes 10a to 10c.

  A regulator 12 having an air pressure gauge 12 a is provided between the electromagnetic air pump 6 and the branch adapter 7. Although a pressure gauge is attached to adjust the air pressure to an appropriate value, the pressure gauge may be omitted. The adjustment / measurement range of the air pressure is exemplified by 0 to 1.0 Mpa. Adjustment of the air volume is performed by turning a dial of the regulator 12.

  The electromagnetic air pump 6 and the regulator 12 are connected by a pipe 13.

  A method of using the bedding cover 1 and a method of washing will be described. The assembling method is as follows. The slider 3a is opened, the three-dimensional net-like structure 2 is accommodated in the fiber cover 4 from the opening, and the pipes 10a to 10c bound by the fastener 11 are arranged on the surface of the strip 5a along the longitudinal direction thereof. The band 5b is adhered to the band 5a at an appropriate position of the pipes 10a to 10c in the band 5b, and the pipes 10a to 10c are temporarily fixed. The other end portions 9a to 9c are respectively inserted into gaps on the side surface 2e of the three-dimensional network structure 2. Close the slider 3a. The disassembly method may be performed in the reverse order. After disassembling the bedding cover 1, the three-dimensional net-like structure 2 is washed and the fiber cover 4 is washed.

  By adjusting the three-dimensional net-like structure 2 and the fiber cover 4 to an appropriate range of 2 ° C. or less of the average value of the human body temperature, an appropriate cooling sensation can be secured. For example, assuming that the room air temperature is 30 ° C. and the average value of the body temperature is 36 ° C., when the air conditioner is not used, the temperature average value of the three-dimensional network structure 2 and the fiber cover 4 is set to 30 to 30, for example, by using room temperature air. It can be kept at 34 ° C. By using the normal temperature air of the outside air or the indoor air, the heat can be eliminated and the human body can be prevented from being too cold. When the air conditioner is used, the indoor air is controlled at, for example, 25 to 28 ° C., and the temperatures of the three-dimensional net structure 2 and the fiber cover 4 are also controlled to the same degree, so that it is comfortable.

  The temperature can be adjusted by increasing or decreasing the air volume of the electromagnetic air pump 6. Electricity bills can also be reduced. Since the air volume is smaller than that of the air conditioner, it is not too cold and is suitable for health.

  Since the indoor air or the outside air can be continuously supplied to the three-dimensional network structure 2 through the pipes 10a to 10c by the electromagnetic air pump 6, the supply air is three-dimensionally diffused into the three-dimensional network structure 2. Even if the three-dimensional network structure 2 and the fiber cover 4 are heated by the temperature of the human body and rise in temperature, the temperature of the outside air or indoor air is lower than the temperature of the human body. Can be naturally reduced, so that the three-dimensional net-like structure 2 is prevented from being too hot or too cold, and an appropriate cooling sensation can be obtained, which is good for health. The user can appropriately adjust the amount of air sent to the three-dimensional network structure by the regulator 12.

  Note that the present invention is not limited to the above-described embodiment, and various modifications, substitutions, deletions, and the like can be made without departing from the technical idea of the present invention. Loss etc. are also included in the technical scope of the present invention. For example, a mattress of a three-dimensional net-like structure without folds has been described, but a mattress having a cut groove, for example, a plurality of short continuous grooves as described in JP-A-2006-6924 etc. It is a matter of course that the present invention can be applied to a mattress or the like in which the continuous groove is widened when the three-dimensional net-like structure is bent upwards. In this case, the pipes 10a to 10c are arranged in a broken line so as not to hinder the expansion. The bedding cover 1 can be used with indoor air or outside air without an air conditioner, but it is also possible to use air conditioned by the air conditioner. The member outside the fiber cover 4 may be boxed or unitized. Although the example of the fiber cover 4 as the inner is shown, the outer surface of the fiber cover 4 is generally covered with an outer, and the bedding cover 1 can be entirely accommodated.

  The bedding cover 1 of the present embodiment can prevent the three-dimensional network structure from being excessively cooled in summer, but can also be used in winter, and can prevent the three-dimensional network structure from being overheated.

  INDUSTRIAL APPLICABILITY The present invention provides temperature control of bedding, for example, a mattress, a pillow, and the like, and particularly provides an appropriate cooling sensation, and thus is effective for countermeasures against extreme heat.
