Description

The present invention relates to combination bedding and overlay mattresses using multiple subbeds and mattresses.

For daily necessities such as bedding, rugs, and cushions that use foamed resin such as urethane foam, for example, when people lie down, the part using the foamed resin is deformed and crushed, and the surface area of the contact part expands. It is constructed to take weight and pressure. The foamed resin contains air bubbles during molding, and after molding, when pressure is applied, the air bubbles deform greatly to reduce the volume, and when the pressure is released, the shape returns to its original shape.

By the way, although it depends on the family structure and housing circumstances, there are cases where a plurality of sleepers use single-sized futons and mattresses side by side at the same time, and each futon and mattress is a single size (for example, 180 cm x 90 cm). Even if there is one, by arranging it side by side, it is possible to utilize the usability close to that of a king size (for example, 200 cm x 200 cm). A gap pad for filling the gap when two mattresses or mattresses are arranged side by side is also known (see, for example, Patent Documents 1 and 2).

An embodiment of the combined bedding of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view for explaining combination bedding using a hardened overlay type mattress 10, in which a pair of mats 12 and 16 as partial beds are arranged side by side. , 16, there is a slight gap 14 even if they are arranged side by side. The upper surface of these mats 12 and 16 allows a person to lie down in their respective postures, and a hardening overlay type mattress 10 is arranged so as to cover the upper surface of the mats 12 and 16, so that the bed as a whole can be used as a large size bed. There will be a combination bedding available.

In this specification, the term "mattress" is widely understood, and it can be used alone, and may be provided with, for example, quilting or a covering cover. It is also possible to cover the hardened overlay mattress 10 with a sheet or towel. Moreover, a pair of partial beds as a platform placed under the hardening overlay type mattress 10 is widely understood, and can be used not only for futon mattresses, single-size beds, queen-size beds, etc., but also for sofas. , cushions, wooden boxes, corrugated cardboard, and other materials, and combinations thereof. One of the partial bases may be fixed to a building or the like. Moreover, it is not necessarily limited to partial tables for residential use, and can be applied to any form in which people lie down or sit in a part of facilities such as hospitals and hotels for business use, vehicles, and other facilities. Firm overlay mattresses are not necessarily for constant use, but also include temporary use.

Various materials can be used as the material for forming the hardened overlay mattress 10. In this case, the hardened overlay mattress 10 is made of a heat-treated high-resilience polyester cotton material. Alternatively, the hardened overlay mattress 10 can be constructed from, for example, a foamed synthetic resin material or a combination of a high resilience polyester cotton heat treated material and an foamed synthetic resin material. When using an expandable synthetic resin material, for example, soft or hard urethane resin, styrene resin, ethylene resin, propylene resin, ethylene-vinyl acetate copolymer resin, or vinyl chloride resin can be used.

The hardened overlay mattress 10 used in the combined bedding of the present embodiment is manufactured by cutting a hardened polyester sheet continuously formed into a desired size. The size of the cured polyester sheet covering the upper surface of the plurality of partial tables is, for example, larger than 140 cm square and smaller than 400 cm square, more preferably 175 cm square or more and 245 cm square or less, and the size is the same in length and width. , and may be of a size that is longer in either the vertical or horizontal direction. Examples of sizes of such a hardened overlay mattress 10 are explained in terms of the relationship between W (width) and L (length) in FIG. , 240 cm x 205 cm, 280 cm x 205 cm, 300 cm x 205 cm, 400 cm x 205 cm, in which L (length) 205 cm can be just the size of 200 cm, and width An increase or decrease of several centimeters is allowed. The thickness of the cured polyester sheet having these sizes is, for example, in the range of 1 cm to 9 cm, more preferably in the range of 1 cm to 4 cm. These sizes and thicknesses are examples, and it goes without saying that other planar sizes and thicknesses can be made by adjusting the cutting method and manufacturing method.

FIG. 3 is a schematic diagram of users 20 and 22 sleeping on the hardened overlay mattress 10 of the present embodiment. If a rigid overlay mattress 10 were not present, the user 22 could become trapped in the gap 14 between a pair of, for example, single size mats 12,16. However, when the hardening overlay type mattress 10 is placed so as to cover the upper surfaces of the pair of mats 12 and 16, neither of the users 20 and 22 will fit in the gap 14, so that they can sleep with peace of mind. be able to. Here, since the hardened overlay type mattress 10 of the present embodiment is not made of foamed resin but is hardened by heat treatment, even if the gap 14 is opened to about several centimeters, it does not cause a large dent, so that the users 20 and 22 can use the mattress. can be stably supported on the upper surface of the cured overlay mattress 10. That is, the users 20 and 22 can adjust their posture when sleeping on the hardened overlay mattress 10 which is harder than urethane but has sufficient cushioning properties, without excessive sinking even on the gap 14. Furthermore, the hardened overlay mattress 10 has excellent air permeability due to its structure, so that a comfortable and sound sleep can be achieved.

The material of the high resilience polyester cotton heat treatment material used for the hardening overlay type mattress 10 is mainly made of 100% polyester cotton. It is made of a cured polyester sheet obtained by laminating the polyester cotton sheets which have been laminated and thermally pressed and then cured by heat treatment. Here, polyester cotton is polyester fiber processed into cotton, and is known for its high elasticity, and is a mass of cotton-like fibers used for sofas, futons, cushions, stuffed toys, and the like. The polyester cotton can be separated by tearing, but in this embodiment, it is pressed to form a sheet of a desired thickness and finished into a cured polyester sheet. The weight of the finished cured polyester sheet is preferably 1.2 kg/m ² or more per unit area due to compression, and typically the cured polyester sheet weighs 1.3 kg. /m ² to 2.0 kg/m ² .

The hardened polyester sheet used in the hardened overlay mattress 10 is a sheet obtained by blending different types of polyester cotton, and in particular, by mixing low-melting polyester cotton, the polyester cotton temporarily melted during heat treatment melts. A state is created in which the polyester cotton containing no particles is mixed, and the low-melting-point polyester cotton is instantaneously solidified by cooling for an extremely short time to obtain a hardened polyester sheet with a high coefficient of restitution that is hard as a whole. For example, the low melting point polyester cotton is 10 to 25% by weight, the recycled polyester cotton is 20 to 50% by weight, and the normal polyester cotton is 30 to 60% by weight. to obtain a polyester cotton sheet. As the low-melting-point polyester cotton, it is also possible to use cotton-like low-melting-point polyester fibers as a whole. Fibers with different compositions can also be used. As ordinary polyester cotton, for example, fibers with a thickness of 12 to 18 denier can be used, and as low-melting polyester cotton, fibers with a thickness of, for example, 4 to 6 denier can be used.

At the time of manufacturing, for example, ordinary polyester cotton, recycled polyester cotton processed into cotton from recycled resources such as PET bottles, and low-melting polyester cotton are uniformly mixed to produce a sheet-like polyester cotton sheet. . This sheet is folded back so as to overlap and fed little by little, and a plurality of polyester cotton sheets are thermocompression bonded. Specifically, the fiber is pressurized into a plate by applying pressure with a hot roller or the like, and at that time, the low-melting-point polyester is melted and maintained at a temperature that reaches every corner of the sheet. For this heating, a relatively large-scale heat treatment device is used, and the polyester cotton sheet is conveyed through the heat treatment device while the low melting point polyester component in the sheet is melted by thermocompression, and is positioned at the end of the heat treatment device. Cooling air is applied by a blower to harden the melted polyester component having a low melting point. The compressed polyester cotton sheet is hardened to a hard state, and the volume of the sheet material is reduced and hardened.

A desired flame retardant or the like can be added to the cured polyester sheet, and it is also possible to mix an antibacterial or antifungal material. The material may be applied to the final product. Further, the cured polyester sheet discharged from the heat treatment apparatus in the form of a web is cut to a desired size and provided with a cover or the like to construct a cured overlay type mattress.

The inventors of the present invention are conducting tests on the high resilience performance of mattresses on which such combined bedding is placed. FIG. 4 shows a drop test of golf balls. In the golf ball drop test, a golf ball 22 was allowed to freely fall from a certain height, 60 cm in this test, onto the surface of the cured polyester sheet of the present embodiment and a high resilience polyurethane material as a comparative example. , and measured the maximum height reached by bouncing on the seat surface. Then, as shown in Table 1 below, the cured polyester sheet 18 of the present embodiment was measured to bounce up to a maximum height of about 33 to 40 cm. On the other hand, when the golf ball 22 was allowed to fall freely against the high resilience polyurethane material 20 as a comparative example, it bounced only up to a height of about 6 cm, indicating a significant difference in the coefficient of restitution.

table 1

The cured polyester sheet used in the cured overlay mattress of this embodiment tends to exhibit high resilience at almost any thickness. When a golf ball is dropped from a hole, the height is about 45 cm or more, and if the thickness is thin, the bounce height tends to be low. For example, when the thickness of the cured polyester sheet is as thin as about 1-2 cm, it can be about 25-30 cm. Since each golf ball has a different rebound, a so-called official ball (weight: 45.93 g or less, diameter: 42.67 mm or more, coefficient of restitution: 0.800 or less) was used.

Next, the flow of the manufacturing process of the hardened polyester sheet used for the hardened overlay type mattress of this embodiment will be briefly described with reference to FIG. As an example, in the production of the hardened polyester pillow member used in the hardened overlay type mattress of this embodiment, a production line equipped with a huge belt conveyor can be used. As cotton, normal polyester cotton, recycled polyester cotton, and low melting point polyester cotton are introduced into the sheet processing machine while being torn by hand (step S10). In this sheet processing machine, the introduced polyester cotton can be mixed well, and the mixed polyester cotton is flattened out (step S12). Next, the polyester cotton sheets discharged from the sheet processing machine are laminated in an assembly line so that several sheets are overlapped (step S14), and then the laminated sheets are compressed while being heated by a hot roll. (S16). In this compression process, the laminated polyester cotton sheets are processed so as to be greatly reduced in thickness. In the manufacturing process of the cured polyester sheet of the present embodiment, heat treatment is subsequently performed after compression (step S18), and heat is applied while ordinary polyester cotton is compressed to melt and spread the low-melting polyester cotton. Finally, by blowing cooling air, the polyester sheet can be hardened by instant curing. The hardened hardened polyester sheet is cut using a cutting device such as a large scroll saw or a laser beam (step S20), and finally a hardened overlay mattress made of a large size hardened polyester sheet can be obtained. (Step S22).

As described above, since the combination bedding of the present embodiment uses a heat-treated material such as high resilience polyester cotton that has been compressed and solidified, when it is placed on the upper surface of a plurality of beddings arranged side by side, there is no dent. The sleeping posture of the user can be stabilized without creating a strain, and the occurrence of health problems such as neck pain and lumbago caused by the sleeping posture can be prevented. In addition, not only when sleeping, but also when exercising using the mattress, for example, it is possible to suppress the occurrence of dents in the gaps, thereby preventing the user from being injured.

In FIG. 6, the base portion 62 is made of, for example, corrugated cardboard measuring 100 cm×100 cm, and assembled to form a box with a square top surface. Even if two such bases 62 are arranged vertically and horizontally to form a base, and the hardened high-resilience overlay type mattress 10 is placed on this base, it functions as a sufficient bedding. Corrugated cardboard does not take up a lot of space to carry and store, and is useful for temporary use, such as camping and shelters. Even on the gap between the bases 62, the sleeping posture can be maintained without excessive sinking, and the hardened high resilience overlay type mattress 10 has excellent air permeability due to its structure. Therefore, the user can sleep comfortably.
