Description

The present invention relates to mattresses.

Conventionally, as an alternative to general futons, air mattresses have been proposed that allow effective use of storage space.
For example, in Patent Document 1, a plurality of air bags are provided, and adjacent air bags are connected by an air supply pipe provided outside the air bags so that air can be exchanged between the adjacent air bags. Disclosed is an air mattress in which a is communicated with.

The air mattress is provided with an air intake/exhaust valve, and when not in use, the internal air is discharged through the air intake/exhaust valve, thereby reducing the volume of the air mattress. This makes it possible to avoid taking up a lot of storage space for the air mattress. In addition, when in use, air is sent into the air bag through the intake/exhaust valve to inflate the entirety of the mattress, thereby enabling it to be used as a mattress.

JP-A-6-7230

However, the above air mattress has the following problems.
That is, the above air mattress requires an operation to send air through an intake/exhaust valve during use. It takes a lot of labor to do this work manually, like a person blowing up a float with his mouth. Therefore, it is recommended to use a mechanical or manual air supply pump. Therefore, conventional air mattresses had to be treated substantially as a set with an air supply pump. Moreover, when using a plurality of such air mattresses at once, it takes a long time to pump air into all the air mattresses even if a pump is used. Therefore, conventional air mattresses are inconvenient to use.

In addition, in the above air mattress, the air bag is provided with an air supply pipe that communicates between the air bags adjacent to each other on the outside. There is a risk that the air pipe itself or the air bag of another air mattress will be ripped, and the like.

The present invention has been made in view of the problems described above. That is, the present invention is easy to store, and has improved usability such as requiring a great deal of labor to put it in a state for use, and requiring the use of a device such as an air supply pump. To provide a mattress in which the mattresses are less likely to get caught on each other, even if it is a case.

The mattress of the present invention is a mattress comprising a bag body having an air intake/exhaust port capable of sucking and exhausting air, and a mat made of urethane foam housed in the bag body, wherein the bag body made of a sealing member is , a plurality of storage sections for storing the mats are provided, and the boundary between one storage section and another storage section adjacent thereto is defined by one or more fixing sections for partitioning the storage sections from each other, and the storage sections from each other. and one or more communication portions that allow gas to flow between the storage portions, and at least one communication portion at the boundary has a core material that allows air to pass through between the adjacent storage portions. and

The mattress of the present invention having the above structure can be compactly accommodated by exhausting the internal air like a conventional air mattress, and does not use human power or an air supply pump unlike the conventional air mattress. It is convenient to use because it is possible to return to the original state from the state where the volume is reduced by exhausting. In addition, in the mattress of the present invention, since a plurality of storage sections for storing mats are provided inside the mattress and communicated with each other at the communication section, it is difficult to get caught by other mattresses when stacked and stored, and the communication section Since a breathable core penetrates through the mattress, smooth ventilation is ensured between adjacent mats even if the inside of the mattress becomes negative pressure.

[First embodiment]
A first embodiment of the mattress of the present invention will be described below. 1 to 5 are used for explanation. FIG. 1A is a top view of the bag body 10 used in the mattress 100 of the first embodiment of the invention, and FIG. 1B is a top view of the mattress 100 of the first embodiment of the invention. 2 is a cross-section II-II end view of the area of the mattress 100 shown in FIG. 1B where the mat 20 is located, and FIG. 3 is a cross-section III-III of the boundary 14 area of the mattress 100 shown in FIG. 1B. FIG. 4 is an end view; FIG. 4A is a side view of the mattress 100 in a folded state. Figure 4B is a side view of the mattress of the first embodiment of the present invention in an evacuated and folded state. Both FIGS. 4A and 4B are side views of the short side of the mattress 100 which is rectangular in top view. FIG. 5 is a top view of a modified mattress 110 of the first embodiment of the invention.

Regarding the present invention, when referring to the vertical direction, there is no particular difference, and it refers to the vertical direction when the mattress is placed on the floor or the like. In the following description, the state in which the mat stored inside the mattress maintains its normal shape and can be used as a mattress is called the used state, and the state in which the air inside the mattress is exhausted and the volume is reduced. It is sometimes called a state of volume reduction. Although the gas filled inside the mattress of the present invention is not particularly limited, it is generally air, and in the following description, an embodiment filled with air will be described.

First, an outline of the mattress 100 will be described.
As shown in FIG. 1B, the mattress 100 of the present embodiment is a mattress comprising a bag 10 having an air intake/exhaust port 40 capable of air intake and exhaust, and a urethane foam mat 20 housed in the bag 10.
The bag body 10 is made of a sealing member, and by closing the intake/exhaust port 40 with air inside, the air is retained even if a weight is placed on the mattress 100, and the mattress 100 can be used. state is maintained.
As shown in FIG. 1A, the bag body 10 is provided with a plurality of storage portions 12 for storing the mats 20 . A boundary 14 between one storage portion 12 and another adjacent storage portion 12 is defined by one or more fixing portions 16 for partitioning the storage portions 12 and air circulation between the storage portions 12. One or more connections 18 are provided to enable At least one communicating portion 18 in one boundary 14 is penetrated by a core material 30 that allows ventilation between adjacent storage portions 12 .

When the mattress 100 having the above structure is not in use, the internal air is discharged from the intake/exhaust port 40, and the inside of the mattress 100 becomes negative pressure, so that the mat 20 elastically deforms and shrinks to reduce the volume. By quickly closing the intake/exhaust port 40 in this state, the mattress 100 can be reduced in volume. The mattress 100 in the reduced volume state can be stored compactly.
When the mattress 100 in the reduced volume state is returned to the use state, air flows into the negative pressure inside the mattress 100 by opening the intake/exhaust port 40, and the mat 20 that has contracted due to elastic deformation is reduced. By expanding to return to its original shape, the bag 10 is expanded from the inside, whereby the shape of the mattress 100 can be restored without manual work. In this manner, the mattress 100 can be returned from the reduced volume state to the used state without the user or the like manually inflating the bag body 10 or using an air supply pump, which is very convenient to use. .

In addition, since the mattress 100 can be stored compactly in a reduced volume state, it is suitable for use as a stockpile for disasters, for example, and it becomes necessary to use a large number of mattresses 100 at once when a disaster occurs. Even when the air intake/exhaust port 40 of each mattress 100 is opened, waiting for the mat 20 to return to its original shape naturally by the restoring force of the mat 20, and then closing the air intake/exhaust port 40, the use state can be quickly performed. It is possible and desirable to provide a mattress 100 of
Details of the mattress 100 are described below.

(Bag body)
The mattress 100 of this embodiment includes a rectangular bag body 10 when viewed from above. The bag body 10 in this embodiment has two or more storage portions 12, and the drawing specifically shows a mattress 100 having six storage portions 12. As shown in FIG. In addition, the mattress of the present invention is not limited to being rectangular when viewed from above, and its shape can be arbitrarily determined.

The bag body 10 is composed of a sealing member. Here, the sealing member refers to a non-air-permeable member, and for example, a resin sheet is preferable because it is easy to process. Examples of resin sheets include vinyl chloride sheets, polyethylene sheets, and polypropylene sheets, but vinyl chloride sheets are preferable from the viewpoint of flexibility and weldability. The thickness of the resin sheet is not particularly limited, and can be appropriately determined within a range in which the mattress 100 can maintain a strength that can withstand normal use.

(storage section)
The arrangement of the plurality of storage portions 12 provided in the bag body 10 is not particularly limited, but FIG. 1A shows a mode in which the plurality of storage portions 12 are continuously provided in the long side direction of the mattress 100 .
The bag body 10 in this embodiment specifically has six storage portions 12 . The six storage portions 12 are all configured in the same shape, and the six mats 20 stored in each storage portion 12 are also configured in the same shape. As shown in FIG. 2, the thickness of the storage section 12 should be approximately the same as the thickness of the mat 20 to be stored, or should be slightly roomier with the mat 20 stored.

The number of storage units 12 in the present invention is not limited to six, and may be two or more. can be folded by bending the For example, from the viewpoint of accommodating the mattress 100, the number of storage sections 12 is preferably three or more, and more preferably four or more. In addition, from the viewpoint of using a part of the mattress 100 as a pillow during use, the number of storage units 12 is two or more, and the storage unit 12 positioned at the end when viewed from the top of the mattress 100 is folded and used as a substitute for a pillow. It may be possible. Such an aspect will be described later as a second embodiment.

(mat)
The mat 20 stored in the storage part 12 is made of polyurethane foam. The mat 20 is shrunk by external pressure to reduce its apparent density, and when the external pressure is removed, the mat 20 has the resilience of returning to its original shape by its own resilience. In order to satisfactorily achieve the above-mentioned restorability, it is preferable that the density of the polyurethane foam constituting the mat 20 is 25 kg/m ³ or more.

The mattress 100 is used with the mat 20 stored in the storage section 12 . The mattress 100 in use can be folded at the boundary 14 as shown in FIG. 4A. A mattress 100 that is not in a reduced state may be folded in this manner and stored in a closet or warehouse.
The boundary 14 in the present embodiment has an appropriate width dimension (distance between adjacent mats 20) so that the boundary 14 can be folded in both the mountain fold and the valley fold in use. More specifically, in the present embodiment, the fixing portion 16 formed at the boundary 14 is substantially half the thickness of the storage portion 12 between the storage portions 12 (mats 20) adjacent to each other with the fixing portion 16 therebetween. , and the width dimension of the boundary 14 including the fixing portion 16 (distance between adjacent mats 20) is about the thickness of one storage portion 12. According to the mattress 100 having such a boundary 14, it is possible to easily fold the mat 20 so that the mat 20 is stacked vertically in the state of use as shown in FIG. 4A.

When the mattress 100 is desired to be compactly accommodated, the air inside the mattress 100 is sucked from the intake/exhaust port 40 to reduce the volume, and the mattress 100 is folded at the boundary 14 as shown in FIG. 4B. If there is room in the storage area of the storage space, the mattress 100 in the reduced volume state may be stored without being folded, or as shown in FIG. It is also possible to

Although the thickness of the mat 20 is not particularly limited, it is preferably 20 mm or more and 100 mm or less, and more preferably 30 mm or more and 70 mm or less, from the viewpoint of cushioning properties during use and accommodation during storage.

(Fixed part)
As shown in FIG. 1A, a fixing portion 16 is provided at a boundary 14 between one storage portion 12 and another storage portion 12 adjacent thereto. Specifically, as shown in FIG. 3, the fixed portion 16 is configured by joining the upper surface and the lower surface that constitute the bag body 10, and the mat 10 stored in each storage portion 12 is attached to the other storage portion 12. It is a part that prevents movement. In other words, the mattress 100 is divided into one storage section 12 and another storage section 12 adjacent thereto by the fixing section 16 .
Here, the bonding may be any means capable of maintaining a state in which the upper surface and the lower surface of the bag 10 are not separated from each other. Examples include, but are not limited to, means such as fusing with an adhesive or bonding with an adhesive or the like.

(Communication part)
If the boundary 14 is completely sealed by the fixing portion 16 , air cannot be sucked and exhausted from all the storage portions 12 through one air intake/exhaust port 40 . Therefore, the boundary 14 is provided with one or more communicating portions 18 that enable air to flow between the storage portions 12 .
Unlike a conventional air mattress having an air supply pipe on the outside, the mattress 100 has a communication part 18 inside the bag body 10, so when a plurality of mattresses 100 are stacked and accommodated, , the occurrence of breakage of the bag body 10 due to contact with each other is prevented.

The communicating portion 18 configured by not joining the upper surface and the lower surface of the bag body 10 described above has the following problems. That is, when the air inside the mattress 100 in use is to be discharged from the intake/exhaust port 40, the inside of the mattress 100 becomes negative pressure, and the upper surface and the lower surface of the bag body 10 are in close contact with each other. In some cases, it was difficult to ventilate.
In order to solve the above problem, in the present invention, a core material 30, which will be described later, is arranged in the communicating portion 18. As shown in FIG. As a result, even when the air inside the mattress 100 is exhausted and the pressure becomes negative, the upper surface side and the lower surface side of the bag body 10 in the communicating portion 18 are close to each other, but a gap that allows ventilation is formed in the communicating portion 18. Secured.

At least one communicating portion 18 may be provided at one boundary 14 , thereby allowing substantially all of the accommodating portions 12 to be ventilated. In this embodiment, the air intake/exhaust port 40 is provided only at one location, but by sucking the internal air from this one air intake/exhaust port 40, the air in all the housing portions 12 can be exhausted. is.
For example, in the present embodiment, as shown in FIGS. 1 and 3, as the communicating portion 18, a first communicating portion 18A and a second communicating portion 18B are provided.

In a mode in which the storage portion 12 is continuously provided in the long side direction in which the long side of the mattress 100 extends, the first communication portion 18A is provided in the cross direction (long side in this embodiment) crossing the long side direction. The connecting part 18 is provided at the end of the mattress 100 near the long side of the fixing part 16 extending in the vertical direction). In other words, the first communication portion 18A is provided at a position closer to the long side of the mattress 100 than the outer edge of the mat 20 when viewed from above. A core member 30, which will be described later, is arranged in the first communicating portion 18A. In this way, when viewed from the top, the core material 30 is arranged in the first continuous portion 18A provided at a position closer to the long side of the mattress 100 than the outer edge of the mat 20, so that the user can lie down on the mattress 100. Consideration is given so that the core material 30 does not easily come into contact with the user's body.
In this embodiment, the first communication portion 18A is provided on both ends of one boundary 14, but the first communication portion 18A may be provided on only one of them.

On the other hand, in a mode in which two or more fixed portions 16 are provided at one boundary 14 , the second communication portion 18B is the communication portion 18 provided between adjacent fixed portions 16 . In other words, the second communicating portion 18B is provided in the middle portion of the mattress 100 in the short side direction when viewed from above.
In this embodiment, the core material 30 is not arranged in the second communication portion 18B. Therefore, when the air inside the mattress 100 is to be exhausted, the second communication portion 18B may be in close contact with the internal negative pressure and substantially unable to ventilate. It does not matter because ventilation is ensured during exhaust by .
The second communication portion 18B is effective for speeding up the restoration of the mat 20 when returning the mattress 100 in the reduced volume state to the use state. As described above, by opening the intake/exhaust port 40 of the mattress 100 in the reduced volume state, air is naturally sucked from the outside of the mattress 100 to the inside, and the bag body 10 is expanded by the restoring force of the mat 20 itself. The mattress 100 is ready for use. At this time, air is easily taken into the mat 20 due to the existence of the second communicating portion 18B provided in the intermediate portion of the mat 20 when viewed from above, and the mat 20 can be quickly restored. I can help.
The present invention includes an aspect in which the core material 30 is also arranged in the second communicating portion 18B, and the second communicating portion 18 exhibits the action of helping the mat 20 to recover quickly even in such an aspect.

As described above, the intake/exhaust port 40 for discharging the air inside the mattress 100 and for supplying (inflowing) the air may be opened and closed repeatedly.

(Core material)
Next, the core material 30 will be explained. The core material 30 is a breathable member arranged across the adjacent storage portions 12 in the communication portion 18 . By arranging such a core material 30, ventilation in the communication part 18 is ensured even when the internal pressure of the mattress 100 becomes negative when the air inside the mattress 100 is exhausted.

As the breathable member constituting the core material 30, the member itself is breathable, for example, a soft member such as a low-density foamed resin, or a bundle of woven fabrics or knitted fabrics. Also, the core material 30 may be a rigid member made of an elastic member such as resin or a spring and having a ventilation hole. In the case of resin, springs, etc., for example, cylindrical pipe-shaped moldings can be used.
However, considering the possibility of giving discomfort to the user and the possibility of damaging the bag body 10, the core material 30 is preferably made of the soft material described above. Further, from the viewpoint of exhibiting the same behavior as the mat 20 when restored, the core material 30 is preferably made of urethane foam.

The core material 30 made of the soft material described above is preferably elongated because it is provided between the adjacent storage sections 12 through the communication section 18 . The cross-sectional shape of the core material 30, which has an elongated shape, is not particularly limited, and as shown in FIG. It can be determined as appropriate.

The core material 30, which is made of a soft material such as urethane foam, is resistant to damage due to repeated bending when the mattress 100 is folded. , is preferably covered with a resin sheet 32 as shown in FIGS. The resin sheet 32 is a sheet-like material having a moderately small thickness, and examples thereof include a vinyl chloride resin sheet, a polyethylene resin sheet, a polypropylene resin sheet, and the like. Moreover, from the viewpoint of ensuring better air permeability of the first communication portion 18A and flexibility when the mattress 100 is folded, the resin sheet 32 is preferably a mesh sheet. The mesh sheet used as the resin sheet 32 is made of any resin such as vinyl chloride resin, polyethylene resin, or polyethylene resin, and the opening of the mesh is not particularly limited. Preferably.

As shown in FIG. 1A, a plurality of first communication portions 18A are provided along the long side of the mattress 100. As shown in FIG. In this embodiment, one core member 30 is provided to extend over the plurality of first communication portions 18A. In other words, in this embodiment, core 30 is continuous along the long sides of mattress 100 . Accordingly, when the mattress 100 is evacuated and reduced in volume, the air inside each storage section 12 can be more smoothly evacuated through the core material 30 .
However, although illustration is omitted, the present invention includes a mode in which a plurality of independent core members 30 are arranged in each first communication portion 18A.

(Modification)
Next, the mattress 110 which is a modification of the mattress 100 of 1st embodiment is demonstrated using FIG.
The mattress 110 differs from the mattress 100 in that it includes a bag cover 50 that encloses the mattress 100 described above, and is configured similarly to the mattress 100 in other respects.
The cover 50 is provided with an opening (not shown) through which the mattress 100 can be put in and taken out, and is configured to cover at least the upper surface side of the mattress 100 included. For example, the cover 50 can be a bag-like structure that covers the entire mattress 100 .

The cover 50 has the air intake/exhaust opening 40 at a position corresponding to the air intake/exhaust opening 40 of the mattress 100 in order to allow air to be exhausted from the air intake/exhaust opening 40 in a state where the mattress 100 is enclosed in the cover 50. A window 42 is provided for exposing the .

A member constituting the cover 50 is not particularly limited, and examples thereof include fabrics such as woven fabrics and knitted fabrics, resin sheets, natural leathers, and artificial leathers. The term "artificial leather" as used herein refers to artificial leather-like artificial sheets including synthetic leather and artificial leather. Synthetic leather is a sheet provided with a resin layer obtained by laminating a resin such as polyurethane on a fabric made of nylon, polyester, or the like. Artificial leather is a sheet made of nonwoven fabric as a base and impregnated with a resin such as polyurethane.

The mattress 100 described above has a boundary 14 between adjacent mats 20, and the boundary 14 is recessed relative to the upper surface of the mat 20 (see FIGS. 2 and 3). The mattress 110 covered with the cover 50 gives a sense of unity in appearance and makes it difficult to feel the dent of the boundary 14 during use. Moreover, the mattress 110 can prevent the bag 10 from being damaged by covering the bag 10 with the cover 50 .

In particular, the mattress 110 having the cover 50 made of natural leather is preferable because it has a luxurious feel and a good touch. Moreover, the mattress 110 including the cover 50 made of artificial leather is preferable because it is possible to provide the mattress 110 with a high-class feeling while suppressing the manufacturing cost.

[Second embodiment]
Next, the mattress 200 which is 2nd embodiment of this invention is demonstrated using FIG. FIG. 6A is a perspective view of the mattress 200 of the second embodiment of the present invention, and FIG. 6B is a perspective view of the mattress 200 with the pillow mat 20B folded toward the mat main body 20A. 6, the resin sheet 32, which is a mesh sheet covering the core material 30, is shown for easy visual recognition.

The mattress 200 has two storage portions 12 of different sizes, and the mats 20 having dimensions corresponding to the sizes of the respective storage portions 12 are stored. It is different from the mattress 100 in the first embodiment in that it is provided only on the side, and the rest of the configuration can be configured similarly to the mattress 100 as appropriate.

More specifically, as shown in FIG. 6, the mattress 200 includes a first storage portion 12A, which is a long storage portion 12, and a relatively short storage portion 12, in the long side direction of the mattress 200. The second storage portion 12B is provided. In the short side direction of the mattress 200, the sizes of the first storage portion 12A and the second storage portion 12B are the same. A boundary 14 is provided between the first storage portion 12A and the second storage portion 12B, and the boundary 14 includes a fixed portion 16 and a communication portion 18 (first communication portion 18A, second communication portion 18B ) is provided.

The first storage portion 12A stores a mat body 20A, which is a mat 20 slightly smaller than the internal dimensions of the first storage portion 12A. On the other hand, the second storage portion 12B stores a pillow mat 20B which is a mat 20 slightly smaller than the internal dimensions of the second storage portion 12B.

In the mattress 200 including the second storage portion 12B in which the pillow mat 20B is stored, the pillow portion 22 can be opened by simply folding the second storage portion 12B in which the pillow mat 20B is stored toward the first storage portion 12A in the state of use. can be configured, and not only mattresses but also pillows can be provided together. In addition, since the mat main body 20A, which is the mat 20 placed in the area where the body is laid down, is a series of mats, it is possible to provide more desirable sleeping comfort compared to the mode in which the area is configured using a plurality of mats 20. .

For example, when the mattress 200 of the present invention is used as a stockpile for use in times of disaster, the mattress and the pillow can be provided simultaneously and easily without having to stockpile pillows separately. It may be difficult for people who are evacuating in the event of a disaster to sleep on a flat mattress alone in an unfamiliar place.

Since the mattress 200 has a simple configuration of the first storage portion 12A in which the mat body 20A is stored and the second storage portion 12B capable of forming the pillow portion 22, the number of the communicating portions 18 is small, and the intake and exhaust are very easy. It is suitable as a stockpile in the event of a disaster because it is smooth to operate and the manufacturing cost is kept low.

Although the first embodiment and the second embodiment of the present invention have been described above, the above-described embodiments do not limit the present invention in any way. For example, in the mattress 100 shown in the first embodiment, the storage section 12 located at the end of the mattress 100 in the long side direction can be folded and used as a pillow. Moreover, the mattress 200 can be used not only as a stockpile for disasters, but also as a mattress in general households. Moreover, as a modified example of the mattress 200, the present invention includes a mode in which the first storage section 12A is divided into two or more storage sections, and independent mats 20 are stored in the respective storage sections.
