Description

[Technical field]

[0001] The present invention relates to combination sleeping equipment and overlay type mattresses that use multiple section platforms and mattresses. [Background technology]

[0002] Everyday items such as bedding, rugs, and cushions that use foamed resins such as urethane foam are usually constructed so that when a person lies down on them, the parts that use the foamed resin deform and collapse, expanding the surface area of ​​the contact area to absorb the weight and pressure. The foamed resin is designed to contain air bubbles during molding, and after molding, when pressure is applied, the air bubbles deform significantly, reducing their volume, and return to their original shape when the pressure is released.

[0003] Incidentally, although it depends on the family structure and housing situation, there are cases where multiple sleepers use single-size futons or mattresses side by side at the same time, and even if each futon or mattress is single-sized (e.g., 180 cm x 90 cm), by using them side by side, it is possible to utilize the usability close to that of a king-size (e.g., 200 cm x 200 cm). Gap pads (see, for example, Patent Documents 1 and 2) to fill the gap when two futons or mattresses are placed side by side in this way are also known. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility model registration No. 3215277 [Patent Document 2] Utility model registration No. 3202978 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even if a gap pad is placed, there is a risk that small children's hands or feet may get stuck in between the edges of the gap pad, resulting in a sleeping position that may be harmful to their health. Also, although there is a demand for larger bedding to provide a larger space to lie down, due to housing circumstances, placing a platform that takes up a large area of ​​the floor is often avoided, and when using a sturdy, fixed platform or mat, it can sometimes get in the way.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a combination sleeping piece that is used as a bedspread in combination with a mattress and has a structure that allows a user to sleep comfortably while securing a wide surface area. [Means for solving the problem]

[0007] In order to solve the above-mentioned technical problems, the combination sleeping equipment of the present invention is a combination sleeping equipment comprising a platform placed on a floor surface and a mattress placed on the top surface of the platform, The platform is provided with a futon, a bed or a mattress. The upper surfaces of the mattress are joined together so that they are continuous. It is made of foaming synthetic resin material, high-resilience polyester cotton heat treatment material, or a combination of these, It is characterized in that it is formed in a size that covers almost the entire top surface of the base.

[0008] In the combination bedding according to the embodiment of the present invention, the mattress can be made of various materials, for example, foaming synthetic resin material, high-resilience polyester cotton heat-treated material, or a combination of these. Examples of foaming synthetic resin material include soft or hard urethane resin, styrene resin, ethylene resin, propylene resin, ethylene-vinyl acetate copolymer resin, and polyvinyl chloride resin. As the high-resilience polyester cotton heat-treated material, a material that can be prepared by the manufacturing method described below can be used, and a blend of polyester cotton and cotton can also be used.

[0009] The mattress used in the combination bedding according to a preferred embodiment of the present invention can be formed by cutting to the desired size. For example, the size across the upper surface of the multiple mattress base sections is greater than 140cm square and less than 300cm square, and more preferably greater than 175cm square and less than 245cm square. The mattress is not limited to having the same length and width, and may have a size in which either the length or width is longer.

[0010] The mattress used in the combination bedding according to the preferred embodiment of the present invention may have a thickness in the range of 1 cm to 4 cm, more preferably in the range of 1.5 cm to 3.3 cm. The weight per unit area of ​​the mattress of the combination bedding according to the preferred embodiment of the present invention is 1.2 kg / m. 2 or more, more preferably 1.5 kg / m 2 Or it can be more.

[0011] Furthermore, in the mattress used in the combination bedding according to a preferred embodiment of the present invention, the surface repulsive force of the mattress can be set such that, for example, when a golf ball is allowed to freely fall from a height of 60 cm, the height reached by the initial repulsive force is approximately 25 cm or more, more preferably approximately 28 cm or more.

[0012] Such combination bedding has a plurality of partial bases that constitute a base, and the plurality of partial bases can be constructed with various members according to the situation. In this specification, the partial base is broadly interpreted, and may be any member that can support the mattress on a surface. Examples of partial bases include, for example, futons, single-size and queen-size beds, as well as sofas, cushions, wooden boxes, cardboard boxes, orange boxes, tea boxes, containers for carrying alcohol bottles, and other materials, and combinations thereof. A part of the partial base may be fixed to a building or the like. In addition, it is not necessarily limited to bedding for residential use, but can be applied to any form of use such as a person lying down or sitting in a commercial facility such as a hospital or hotel, or in a vehicle or other facility. The mattress is not necessarily limited to one that is used all the time, and also includes temporary use.

[0013] The partial bases used in the combination bedding in this embodiment can be, for example, boxes of the same size combined together, or foldable materials such as foldable cardboard can be used. Also, a container for storing liquids such as water can be used as the partial base, and further, the upper surface of the multiple continuous partial bases can include a slope in part.

[0014] In addition, the overlay-type mattress according to an embodiment of the present invention is an overlay-type mattress used in the assembled bedding described above, and is characterized in that the size of the overlay-type mattress is such that it covers almost the entire top surface of the base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] An embodiment of the combination sleeping equipment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic perspective view for explaining the combination sleeping equipment using a hardened overlay type mattress 10. Mats 12 and 16 are arranged as a pair of partial bases arranged side by side, and there is a small gap 14 between these mats 12 and 16 even when arranged side by side. The upper surfaces of these mats 12 and 16 are designed so that a person who wants to sleep can lie down in any posture, and the hardened overlay type mattress 10 is arranged to cover the upper surfaces, resulting in a combination sleeping equipment that can be used as a large-sized bed as a whole.

[0017] In this specification, the term "mattress" is broadly understood and may be used alone, and may be provided with, for example, quilting or a covering. The hardened overlay mattress 10 can also be used by covering it with a sheet or towel. A pair of partial platforms arranged under the hardened overlay mattress 10 is also broadly understood and includes not only futons and single-size and queen-size beds, but also sofas, cushions, wooden boxes, cardboard, and other materials, and combinations thereof. One of the partial platforms may be fixed to a building or the like. In addition, the present invention is not necessarily limited to partial platforms for residential use, and can be applied to any form of use, such as in commercial use in hospitals and hotels, vehicles, and other facilities where people lie down or sit. The hardened overlay mattress is not necessarily limited to those used constantly, and also includes temporary use.

[0018] Various materials can be used as the material for the hardened overlay-type mattress 10, but here the hardened overlay-type mattress 10 is made of a heat-treated high-resilience polyester cotton material. Alternatively, the hardened overlay-type mattress 10 can be made of, for example, a foaming synthetic resin material, or a combination of a heat-treated high-resilience polyester cotton material and a foaming synthetic resin material. When a foaming synthetic resin material is used, for example, soft or hard urethane resin, styrene resin, ethylene resin, propylene resin, ethylene-vinyl acetate copolymer resin, or polyvinyl chloride resin can be used.

[0019] The hardened overlay mattress 10 used in the combination bedding of this embodiment is manufactured by cutting the hardened polyester sheet, which is continuously formed by hardening, into a desired size. The size of the hardened polyester sheet across the upper surface of the multiple partial bases is, for example, larger than 140 cm square and smaller than 400 cm square, and more preferably, 175 cm square or more and 245 cm square or less. The length and width are not limited to the same size, and either the length or width may be longer. Examples of sizes of such a hardened overlay mattress 10, when explained in terms of the relationship between W (width) and L (length) in Fig. 2, can be, for example, 140cm x 205cm, 160cm x 205cm, 180cm x 205cm, 200cm x 205cm, 240cm x 205cm, 280cm x 205cm, 300cm x 205cm, and 400cm x 205cm, in which L (length) of 205cm may be exactly the same as 200cm, and the width is also allowed to increase or decrease by a few centimeters. The thickness of the hardened polyester sheet having these sizes is, for example, in the range of 1cm to 9cm, and more preferably in the range of 1cm to 4cm. These sizes and thicknesses are merely examples, and it goes without saying that other planar sizes and thicknesses can be obtained by adjusting the cutting method and manufacturing method.

[0020] FIG. 3 is a schematic diagram of a state in which users 20 and 22 are sleeping using the hardened overlay-type mattress 10 of this embodiment. If the hardened overlay-type mattress 10 is not present, there is a possibility that the user 22 may get stuck in the gap 14 between a pair of, for example, single-sized mats 12 and 16. However, when the hardened overlay-type mattress 10 is placed so as to cover the upper surfaces of the pair of mats 12 and 16, neither the user 20 nor 22 gets stuck in the gap 14, and the user can sleep in peace. Here, since the hardened overlay-type mattress 10 of this embodiment is not made of foamed resin but is hardened by heat treatment, even if the gap 14 opens to a size of several centimeters, no large depression is generated, and the users 20 and 22 can be stably supported on the upper surface of the hardened overlay-type mattress 10. In other words, the users 20, 22 can maintain their sleeping posture on the hardened overlay-type mattress 10, which is harder than urethane but has sufficient cushioning, even on the gap 14, without sinking excessively, and furthermore, since the hardened overlay-type mattress 10 has excellent breathability due to its structure, they can have a comfortable, restful sleep.

[0021] The material of the high-resilience polyester cotton heat-treated material used in the hardened overlay mattress 10 is mainly made of 100% polyester cotton, and is made by blending different types of polyester cotton and processing them into sheets, laminating the polyester cotton sheets processed into sheets, heat-pressing them, and then hardening them by heat treatment to form a hardened polyester sheet. Here, polyester cotton is polyester fiber processed into cotton, known for its high elasticity, and is a mass of cotton-like fibers used in sofas, futons, cushions, stuffed toys, etc. Polyester cotton can be torn off and separated, but in this embodiment, it is pressed to form a hardened polyester sheet of the required thickness. The weight of the completed hardened polyester sheet is 1.2 kg / m2 per unit area because it is compressed. 2 or more, typically 1.3 kg / m for cured polyester sheets.2 ~2.0kg / m 2 The weight ranges from 0.01 to 0.01 mm.

[0022] The hardened polyester sheet used in the hardened overlay mattress 10 is a sheet obtained by blending different kinds of polyester cotton. In particular, by mixing low-melting polyester cotton, a state is created in which polyester cotton that melts temporarily and polyester cotton that does not melt are mixed during heat treatment, and then, by cooling for an extremely short time, the low-melting polyester cotton is instantly solidified to obtain a hardened polyester sheet that is hard overall and has a high resilience coefficient. For example, a polyester cotton sheet is obtained by uniformly mixing each polyester cotton at a weight ratio of 10 to 25% for low-melting polyester cotton, a weight ratio of 20 to 50% for recycled polyester cotton, and a weight ratio of 30 to 60% for normal polyester cotton. For the low-melting polyester cotton, a polyester fiber that is made into a cotton-like form overall with a low melting point can be used, and a fiber with a different composition in the core-sheath structure, such as a polyester cotton core and a copolymer polyester or polyethylene sheath, can also be used. For normal polyester cotton, for example, a fiber with a thickness of 12 to 18 denier can be used, and for low-melting polyester cotton, a fiber with a thickness of 4 to 6 denier can be used.

[0023] During production, for example, normal polyester cotton, recycled polyester cotton made by processing recycled resources such as PET bottles into a cotton-like form, and low-melting polyester cotton are mixed uniformly to produce a polyester cotton sheet in sheet form. The sheet is folded over so as to overlap, and fed little by little, and multiple polyester cotton sheets are heat-pressed together. Specifically, pressure is applied by a heat roller or the like to press the fibers into a plate shape, and the low-melting polyester is maintained at a temperature at which it melts and 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 polyester component in the sheet is melted by heat pressing, and cooling air is applied by a blower located at the end of the heat treatment device to harden the molten polyester component with a low melting point. The compressed polyester cotton sheet hardens into a hard state, reducing the volume of the sheet material and hardening it.

[0024] It is possible to add a desired flame retardant to the cured polyester sheet, and it is also possible to mix in antibacterial or antifungal materials, but the desired flame retardant, antibacterial or antifungal materials may be applied to the final product. The cured polyester sheet discharged from the heat treatment device in web form is cut to the required size, and a cover or the like is provided to form a cured overlay mattress.

[0025] The present inventors have conducted tests on the high resilience performance of mattresses on which such combined bedding is placed. Figure 4 shows a golf ball drop test. In the golf ball drop test, a certain golf ball 22 was dropped freely from a certain height, 60 cm in this test, onto the surface of the hardened polyester sheet of this embodiment and onto the surface of the high resilience polyurethane material as a comparative example, and the maximum height reached by the ball after bouncing off the surface of each sheet was measured. As shown in Table 1 below, the hardened polyester sheet 18 of this embodiment bounced up significantly, up to a maximum height of about 33 to 40 cm. In contrast, when the golf ball 22 was dropped freely onto the high resilience polyurethane material 20 as a comparative example, the ball only bounced up to a height of about 6 cm, indicating a significant difference in the resilience coefficient.

[0026] Table 1 JPEG2025013685000002.jpg45170

[0027] The cured polyester sheet used in the cured overlay type mattress of this embodiment tends to show high resilience regardless of the thickness. For example, in the case of a cured polyester sheet with a thickness (height) of more than 10 cm, when a golf ball is dropped from a height of about 60 cm, the ball will bounce to about 45 cm or more, and when the thickness is thinner, the ball will bounce to a lower height. For example, when the cured polyester sheet is thin, about 1 to 2 cm, the ball may bounce to about 25 to 30 cm. Since the resilience of golf balls varies, so-called official balls (weight: 45.93 grams or less, diameter: 42.67 mm or more, resilience coefficient: 0.800 or less) were used.

[0028] Next, the flow of the manufacturing process of the hardened polyester sheet used in the hardened overlay type mattress of this embodiment will be briefly described with reference to FIG. 5. As an example, in the manufacture of the hardened polyester pillow member used in the hardened overlay type mattress of this embodiment, a manufacturing line with a huge belt conveyor can be used. First, a craftsman engaged in the manufacture tears off normal polyester cotton, recycled polyester cotton, and low melting point polyester cotton as raw polyester cotton with his hands and introduces them into a sheet processing machine (step S10). In this sheet processing machine, the introduced polyester cotton can be mixed well, and the mixed polyester cotton is pressed and stretched flat (step S12). Next, in the flow process, the polyester cotton sheets discharged from the sheet processing machine are stacked so that several sheets overlap each other (step S14), and then the stacked sheets are compressed while being heated by a heat roll (S16). In this compression process, the polyester cotton sheets stacked are processed so that their thickness is greatly reduced. In the manufacturing process of the cured polyester sheet of this embodiment, after compression, a heat treatment is subsequently performed (step S18), and the ordinary polyester cotton is heated while compressed to melt and spread the low melting point polyester cotton over the entire surface, and finally, cooling air is applied to instantly harden the cured polyester sheet. The cured cured polyester sheet is cut using a cutting device such as a large jigsaw or laser beam (step S20), and finally, a cured overlay type mattress made of a large-sized cured polyester sheet can be obtained (step S22).

[0029] As described above, the combination bedding of this embodiment uses compressed and solidified high-resilience polyester cotton heat-treated material, and when placed on the top surface of multiple beddings arranged side by side, it can stabilize the user's posture when sleeping without creating a depression, and can prevent health problems caused by the sleeping posture, such as neck pain and back pain. In addition, it is not limited to when sleeping, but can also prevent the occurrence of depressions in gaps when exercising using the mattress, for example, and can prevent the occurrence of injuries to the user.

[0030] FIG. 6 is a perspective view showing a combination bedding using the hardened high-resilience overlay mattress 10. In FIG. 6, the base 62 is, for example, made of cardboard and is 100 cm x 100 cm in size, and when assembled, forms a box with a square top. Two such bases 62 are arranged lengthwise and widthwise to form a base, and the hardened high-resilience overlay mattress 10 is placed on it, and it functions as a sufficient bedding. Cardboard does not take up much space for carrying and storing, and is useful for temporary use, for example, in camps and shelters. Even on the gaps between the bases 62, the user can maintain his / her sleeping position without sinking excessively, and the hardened high-resilience overlay mattress 10 has excellent breathability due to its structure, so the user can sleep comfortably.

[0031] 7 shows a combination sleeping arrangement in which a hardened high-resilience overlay mattress 30 is placed on the top surface of three mats 32, 34, 36. Here, the three mats 32, 34, 36 are all the same size, for example, 120 cm x 200 cm, and the mattress 30 is an extra-large size, for example, 370 cm x 205 cm, so as to cover the surface of the three mats arranged side by side.

[0032] 8 shows a combination sleeping arrangement in which a hardened high-resilience overlay mattress 30 is used on the top surfaces of four mats 32, 34, 36, 39. Here, the three mats 32, 34, 36, 39 are the same size, for example, 100 cm x 200 cm, and the mattress 30 is an extra-large size, for example, 420 cm x 205 cm, so as to cover the surfaces of the three mats arranged side by side.

[0033] 9 shows a combination bedding using a hardened high-resilience overlay type mattress 30 on the upper surface of two mats 32, 38. Here, the two mats 32, 38 are not the same size, for example, one mat 32 is 120 cm x 200 cm, and the other mat 38 is 240 cm x 200 cm. The mattress 30 is arranged so as to cover the two mats 32, 38 arranged side by side, and is made to be an extra large size of, for example, 370 x 205 cm.

[0034] 10 is an assembly diagram showing an example of a platform used for assembled bedding, where (a) shows the cardboard boxes 72 that form the platform stacked in an unfolded state, and (b) shows the cardboard boxes 72 assembled into flat rectangular boxes and arranged on the floor in a matrix of 3 rows and 3 columns. By using foldable cardboard boxes 72 in this way, they can be stored in a warehouse or other space-saving manner, and in the event of a disaster, they can be assembled and arranged as a platform on which a hardened high-resilience overlay mattress 10 (not shown) can be placed.

[0035] FIG. 11 is a perspective view showing another example of a platform used in the assembled bedding. The platform arranged under the hardened high-resilience overlay-type mattress 10 is a plurality of liquid storage containers 74 constituting a plurality of partial platforms, and in this embodiment, a total of four rectangular liquid storage containers 74 are placed. The upper surfaces 76 of the four liquid storage containers 74 form a flat surface, for example, about 240 cm x 240 cm in size, with some gaps, on which the hardened high-resilience overlay-type mattress 10 can be placed. The liquid storage containers 74 are made of resin, for example, polypropylene resin or polyethylene resin, or polyvinyl chloride resin or other soft resins. By forming the upper surface 76 of the liquid storage container 74 from a soft material, it is also possible to make the assembled bedding of this embodiment into a water bed. A liquid inlet 78 is provided on the upper surface of the liquid storage container 74, from which liquid such as water can be poured. In the event of a disaster, the water stored in the liquid storage container 74 can also be used as water for daily life such as bathing, washing, and using the toilet.

[0036] FIG. 12 shows yet another example of a prefabricated bedding unit that partially uses a drawer furniture unit. A hardened high-resilience overlay mattress 50 is held on the wall via a holder 58 in a rolled, pull-out state, and a storage furniture 54 with a drawer 56 is disposed below the mattress. Normally, the hardened high-resilience overlay mattress 50 is held on the holder 58 in a rolled state against the wall, but when in use, the hardened high-resilience overlay mattress 50 is pulled out and spread out on the storage furniture 54 and four boxes 52 that function as additional partial stands. The hardened high-resilience overlay mattress 50 can be stored against the wall not only in a rolled state, but also by folding it or by being a separate unit that is placed on the wall only when necessary.

[0037] 13 and 14 show modified examples of the hardened high-resilience overlay mattress of the present invention. FIG. 13 shows a two-layered sheet, with the lower layer being a hardened polyester sheet 40 and the upper layer being a urethane sheet 42. The thickness of each resin layer can be adjusted as desired, and when the hard hardened polyester sheet 40 alone is too hard, the upper layer urethane sheet 42 provides softness. Even with this configuration, the lower layer hardened polyester sheet 40 functions as a core to prevent the occurrence of depressions, etc. Also, in FIG. 14, the upper and lower layers are hardened polyester sheets 44 and 40, and the middle layer is a urethane sheet 42. By using such a three-layered structure, the rigidity of the sheet itself can be adjusted by the thickness of the middle layer urethane sheet 42, while both sides are made of hardened polyester sheets 44 and 40.

[0038] 15 shows an example of assembled bedding in which multiple partial bases on which hardened high-resilience overlay-type mattresses 66 are placed are made up of three mats 62 and a spacer 64 with a wedge-shaped cross section and a slope. By placing the spacer 64 on the three mats 62, the upper surface of the partial base becomes a surface that includes a slope, and by placing the hardened high-resilience overlay-type mattress 66 on top of that, the hardened high-resilience overlay-type mattress 66 takes on a shape that reflects the slope of the bottom surface, and the shape of the hardened high-resilience overlay-type mattress 66 can be changed to one that has a slope other than just a horizontal surface.
