[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat which can be easily used as a sofa.

[0002]

2. Description of the Related Art The most common conventional mattress (or mattress) is such that a mass of blanket cotton or polyurethane foam used as a filling material is sealed in the brim so that it does not move in the brim. Configuration. Therefore, when a conventional mat having the above-described structure is used, the familiarity between the user's body and the mat is poor, and the mat is giving a feeling of oppression to the user's body. , The back, waist,
Pressure from the mattress is applied to the thighs and other areas, causing the sleepless movement to be performed unconsciously at midnight while sleeping, so that sleep may be impaired, and people who are bedridden for a long time may suffer from bedsores The problem is that it can cause unusual situations.

[0003] As a solution to the above-mentioned problems, there have conventionally been, for example, (1) a mattress having a configuration in which a gas or a liquid used as a filling is sealed in a sealed container made of a flexible material; 2) Beddings such as cushions and cushions in a configuration mode in which granular Styrofoam used as a filling material is sealed in the camera side in such an amount as to be movable in the camera side.

[0004]

In a mattress constructed by implementing the solution as exemplified in the above (1),
As a problem, it is still a problem to give a sleeper who uses it a feeling that a feeling of oppression is still applied to the body at bedtime. However, a solution as exemplified in the above (2) is implemented. With the mats and cushions configured as above, the distribution of the padding can be easily transformed into a state that conforms to the unevenness of the user's body at the time of use, so that the problems described above can be solved. It was.

[0005] However, various proposals relating to conventional futons and cushions constructed by implementing the solution as exemplified in the above (2) merely suggest new ideas for mats and cushions. It was only a stage, far from a futon or cushion with a configuration and function suitable for practical use, and has not been put to practical use until now. The present invention provides the aforementioned (2)
A sofa-bed that has excellent functions that could not be obtained with conventional mats and cushions constructed based on the solution as exemplified in the above, and has a configuration and performance suitable for practical use It is to provide a futon.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the accompanying drawings, the specific contents of a mat that also serves as a sofa according to the present invention will be described in detail. First, prior to the description of various embodiments relating to a sofa mat also used as a sofa of the present invention, the volume (volume) on the side of the mat.
The ratio of the volume (volume) of the granular stuffing sealed in the futon side to the ratio (filling rate of the granular stuffing sealed in the futon side) will be described with reference to FIG. FIG. 8 is a plan view showing an empty bag-shaped blanket side 2 without any padding used for explaining the filling rate of the granular padding in the sofa / bed mat of the present invention. In the case 2 shown in FIG. 8, A and B are the vertical and horizontal dimensions (length) of the empty bag-like case 2.
In the case where the side 2 shown in FIG. 1 is the side of a mattress that is a standard size in Japanese standards for mats, the vertical dimension A is 200 cm and the horizontal dimension B is 105 cm.

[0008] Conventional mat mats, which are formed by enclosing fillings with flat-shaped cotton mats on the mat side, usually have a size of 12 m.
It is made as thick as about cm. Then, using the mattress side of a mattress of a standard size such that the vertical dimension A is 200 cm and the horizontal dimension B is 105 cm,
When a mat with a thickness of 12 cm is made, the vertical and horizontal dimensions of the completed mat are, of course, 200 cm in height and 105 cm in the horizontal and vertical dimensions of the above-mentioned flat state.
m.

[0009] By the way, in the mat of the present invention, the granular stuffing on the side of the bed at the contact portion with the body of the sleeping person moves quickly and smoothly within the group, and the granular stuffing on the side of the bed is removed. It is constituted by the amount of granular stuffing that can be made to be in a distribution state that is familiar to the unevenness of the sleeping person's body is enclosed in the camera side, and in the case where the mat is a winter mat, for example, As the above-mentioned granular filling to be encapsulated in the futon side, styrene foam beads having a diameter of, for example, 2 mm to 6 mm can be used as the thermal insulating stuffing, and when the mat is a summer mat, for example. Has a diameter of 4 mm to 5 mm and a length of 5 m
Granular polyethylene pipes, such as m to 7 mm, or low thermal insulating granular fillings such as buckwheat hulls can be used.

[0010] As described above, the granular stuffing on the side of the bed at the contact portion with the body of the sleeping person is quickly and smoothly moved inside the bun, and the distribution state of the granular stuffing on the side of the bed is changed. The filling rate of the granular stuffing that can be quickly and smoothly adjusted to the distribution conforming to the unevenness of the sleeping person's body is determined based on the reference volume Vs on the futon side and the volume of the granular stuffing actually enclosed in the futon side ( (Volume) Vt and the numerical value (100 V) of the volume percentage (percentage) of the granular filling.
t / Vs)% is considered appropriate.

By the way, the reference volume V on the side of the bun, which is used in calculating the numerical value of the volume percentage of the granular filling described above.
As s, for example, when the gasket side in a state where the granular filling is not enclosed has a vertical outer shape having a size of the vertical dimension A and the horizontal size B, a flat gasket cotton is put in the gasket side. Put the volume of the umbrella in a state where it is made to have a thickness C by inserting it as a filling, and the reference volume V on the first umbrella side
It may be used as s1.

However, as described above, when a cushion having a thickness of C is formed using the cushion side of a mattress having a standard size such that the vertical dimension A is the horizontal dimension B, Naturally, the vertical and horizontal dimensions of the completed futon are smaller than the vertical and horizontal dimensions A and B of the above-mentioned flat state on the futon side, so that the numerical value (100 Vt / Vs) Although the reference volume Vs1 on the side of the bun used for calculation of% is smaller than A × B × C liter, the reference volume Vs1 on the side of the bun is set as A × B × C liter, and Even if the calculation of the numerical value is performed, there is no practical problem.

Further, as the reference volume Vs on the futon side used for calculating the numerical value of the volume percentage of the granular filling, for example, in the state where the granular filling is not put, the vertical and horizontal are A, as described above. Assuming that a rectangular shape having a height of A and a circumference of 2B is formed by a rectangular shape having a dimension of B, the volume of the cylindrical shape is defined as a second size. Can be used as the reference volume Vs2.

As described above, of the two types of reference volumes Vs1 and Vs2 of the group, which are exemplified as the reference volume Vs of the group used in calculating the numerical value of the volume percentage of the granular filling, the first group has the same configuration. The reference volume Vs1 is (A × B × C)
Liters, and the reference volume Vs2 of the second group is Aπ (B / π) (B / π) liters. Therefore, (A × B × C) ): A
There is a relationship of π (B / π) (B / π) = 1: B / Cπ.
Here, π is a circle ratio.

FIG. 1 is a view for explaining an embodiment of a mat that also serves as a sofa according to the present invention. FIG. 1A is a perspective view of a mat that also serves as a sofa, and FIG. 1 (a) is a longitudinal sectional view taken along the line XX in FIG. 1 (a), and FIG. 1 (c) is a state in which a sleeper is sleeping on the mat shown in FIG. 1 (a). 3 is a vertical cross-sectional view at the position of the line XX in FIG.
, A reference numeral 4 denotes an overall reference number of the pillow; 5, a pillow side attached to the skirt side 2; 6, a granular stuffing sealed in the pillow side 5; As the skirt side 2 and the pillow side 5 of the above-mentioned mat skirt 1, for example, a cotton broad ground is used. The granular packing 3 to be enclosed in the above-mentioned futon side 2, in the case of a mat for winter, as the heat-insulating granular stuffing 3, for example, styrene foam beads having a diameter of 2 mm to 6 mm can be used. Inside the mat side 2 of the mat for summer and the pillow side 5
As the granular filling 6 to be enclosed in the container, for example, a granular polyethylene pipe or a low heat insulating granular filling such as buckwheat hulls can be used.

As described above, the amount of the granular filling 3 to be enclosed in the skirt 2 is set to such an amount that it can be easily moved in the skirt 2. The appropriate amount of the granular filling 3 to be enclosed in the bed varies depending on the weight of the sleeping person. Shikamadan 1 of the embodiment described with reference to FIG.
Then, when the sleeping person with the head resting on the pillow 4 shakes his body lightly, the granular stuffing 3 in the skirt 2 moves in the skirt 2,
As shown in FIG. 1 (c), the granular stuffing 3 in the skirt 2 adapts to the body shape of the sleeping person and becomes deformed.

The mat 1 of the embodiment described with reference to FIG.
However, in the case where an appropriate amount of the granular stuffing 3 for the sleeping person is encapsulated in the gasket side 2, that is, the granular stuffing 3 having an appropriate filling rate for the sleeping person is enclosed in the gastronomic side 2. The sleeping person who sleeps in the mattress 1 in the state,
The waist, thighs, and feet sink to the desired depth of the sleeping person, making it extremely comfortable to sleep. Since the granular stuffing 3 is granular, the blood pressure of the whole body is improved while sleeping due to the acupressure effect. In addition, a good sleep can be expected by using a material with good heat radiation performance so that the head does not feel hot as the granular filling 6 to be enclosed in the pillow side 5 attached to the skirt 2.

As shown in FIG. 1 (c), the granular stuffing 3 in the mat side 2 of the mat skirt 1 is adapted to the irregularities of the body shape of the sleeping person and becomes deformed. In order to compensate for this point, it is desirable to use a commercially available mat, a mattress, a polyurethane mat, an air mat, or a pad under the mat to make up for this point. Also, cushions may be used only for the back and waist for underlaying.

By the way, the amount of the granular stuffing 3 which can be easily moved in the skirts side 2 of the mattress and which is appropriate for the sleeping person is determined by the amount of the granular stuffing 3 to be enclosed in the skirts 2.
A large number of mats were prepared by changing the amount of the various types of mats, and actually sleeping on each of the mats described above, the relationship between the amount of the granular filling 3 enclosed in the group 2 and the comfort was examined. Can be determined by:

FIG. 9 shows that the vertical dimension A is 100 cm and the horizontal dimension B
When styrene foam beads having a diameter of 3 millimeters (about 2 mm to 6 mm) are placed as granular fillings 3 on the side 2 in FIG. The vertical dimension A and the horizontal dimension B of the mat that change according to the change in the amount of the granular filling 3 that has been inserted.
And the change of the thickness C, and the change of the dimensions D, E, F... N, O (see FIGS. 9 and 10) of each part of the mattress when the sleeper lays down on the mattress. It is a figure which shows the investigation result which investigated how the distribution state of the granular stuffing 3 in the camera-band side 2 changes corresponding to the uneven | corrugated state of each part of a person's body. 10 (a) to 10 (e) are symbols A to C indicating the dimensions of each part of the "mat before use" and the dimensions of each part of the "mat in use" in FIG. It is a figure explaining which symbol D-O shows which part of the mat.

In the figure of the survey results shown in FIG. 9, the unit of the amount of filling (granular filling) used at the time of the survey is gram, but the volume (volume) of 1 gram of the styrene foam beads used as the granular filling at the time of the survey is Since the volume is about 100 milliliters, the amount of the (granular) padding 3 shown by weight in FIG. 9 can be easily converted to the volume (volume) value. The numerical data shown in each of the columns D to O in FIG. 9 has a height of 179 cm,
Weight 62Kg, sitting height 90cm, inseam 89cm, shoulder width 42cm, head circumference 60cm, neck circumference 38c
m, bust 90cm, waist 82cm, hip 93cm, around thigh 51cm, around shin 3
6cm, around the ankle 21cm, arm length 73c
m, the circumference of the arm is 26 cm, the length of the wrist is 15 cm, and the length of the foot is 29 cm.

According to the data shown in the survey results of FIG. 9, the sleeping person could feel that the mat was relatively good because 1920 g in the rectangular band 2 having a length of 200 cm and a width of 105 cm. Or, it was the case of three types of mats that were configured by enclosing the granular filling 3 of 2080 g or 2240 g. Among the three types of mattresses, the one that felt the best mattress was a mattress in which 2080 g of granular packing 3 was sealed in the mattress side 2.

When the numerical values of the volume percentages of the two types of granular stuffing used as the packing rate of the granular stuffing in the above-mentioned mat are calculated, 208 in FIG.
In a mat that is configured to encapsulate 0 g (208 liters) of the granular filling 3, a reference volume Vs1 of the first group is set.
= (A × B × C) liter = 200 × 105 × 12 = 2
82.54% volume for 52 liters (filling rate 8
2.54%), and the reference volume V on the second
s 2 = Aπ (B / π) (B / π) = 29.688% volume for 700.6 liters (filling rate 29.688
%).

Among the above three types of mats, the soft mat was felt as a mat having a 1920-gram granular filling 3 enclosed in the mat 2. When the numerical values of the volume percentages of the two types of granular stuffing used as the filling rate of the granular stuffing in this mat are obtained, the 1920 g (192 liter) granular stuffing 3 in the group 2 in FIG. In the mat which is configured by enclosing the reference, the reference volume Vs1 =
(A × B × C) liter = 200 × 105 × 12 = 25
76.19% volume for 2 liters (filling rate 76.19%)
19%), and the reference volume Vs2 on the second
= Aπ (B / π) (B / π) = 27.4% volume (filling rate 27.4%) for 700.6 liters.

Further, of the above three types of mats, one who felt that the mats were firmer was that 2
FIG. 9 shows the percentage of the volume percentage of the two types of granular stuffing used as the filling rate of the granular stuffing in the matting pillow, which is formed by enclosing 240 g of the granular stuffing 3. In a mat that has 2240 grams (224 liters) of the granular filling 3 enclosed in the side 2, a reference volume Vs1 = (A
× B × C) liter = 200 × 105 × 12 = 252 liters, 88.88% volume (filling rate 88.88)
%), And the reference volume Vs2 = A on the second futon side.
π (B / π) (B / π) = 700.6 liters and a volume of 31.97% (filling rate 31.97%).

It is a desirable embodiment to increase or decrease the amount of the granular stuffing 3 to be inserted into the skirt 2 by about 0.25% per kilogram of body weight in response to an increase or decrease in the weight of the sleeping person 7. If the weight of the sleeping person 7 exceeds 100 kg, it is preferable to keep an appropriate amount for the sleeping person weighing 100 kg. By the way, if the amount of the granular stuffing 3 to be sealed in the gasket side 2 is large, the moving rate of the granular stuffing 3 in the gasket side 2 becomes small, resulting in a hard mat, and if the amount of the granular stuffing 3 is small, the gasket side Granular filling 3 in 2
The rate of movement becomes large and it becomes a soft mat.

By providing a control opening or the like with a zipper made of vinyl, for example, on the camera side 2 to increase or decrease the amount of the granular filling 3 to be filled, a mat having the hardness desired by the user can be obtained. Obtained easily. However, in the case of increasing or decreasing the amount of the granular filling 3 to obtain a mat having the desired hardness of the user, the filling of the granular filling 3 into the skirt 2 is performed. The problem is that the operation of increasing and decreasing the amount is complicated.

The above-mentioned problem in the case of obtaining a mat having the desired hardness of the user by increasing / decreasing the filling amount of the granular filling 3 is described in, for example, FIG. As in the embodiment shown in FIG. 2, the problem can be solved by changing the size of the gasket side 2 while keeping the amount of the granular filling 3 sealed in the gasket side 2 unchanged.

FIG. 6 (a) shows, for example, a case in which the granular filling 3 in the mat side 2 of the mat 1 as shown in FIG. FIG. 2 illustrates a mattress 1 configured to be folded at a longitudinal fold 8 of the skirt 2 at an arbitrarily set portion of a space portion generated near the other side edge 2 b of the side 2. Therefore, in the mat 1 shown in FIG. 6A, the capacity of the mat 2 is reduced in a state where the lateral width B is shorter than that of the mat 1 shown in FIG. 6 is the same as the amount of the granular stuffing 3 in the mattress side 2 in the mattress 1 shown in FIG. 1 and therefore, naturally, (a) in FIG. The values of the volume percentages of the two types of granular stuffing used as the packing ratio of the granular stuffing in the mat 1 shown in) are the volumes of the two types of granular stuffing used as the filling rate of the granular stuffing in the mat 1 shown in FIG. It is larger than the percentage value.

The degree of the increase in the numerical value of the volume percentage of the two types of granular stuffing used as the packing rate of the granular stuffing in the matting pillow 1 shown in FIG. Granular stuffing 3 in the gasket side 2
The position of the vertical fold 8 of the skirt side 2 in an arbitrarily set portion of the space created near the other side edge 2b of the skirt side 2 is changed by moving the skirt 8 toward the one side edge 2b. Can be easily adjusted by
In order to ensure that the mat 1 has the hardness desired by the user, complicated adjustment means such as the operation of increasing or decreasing the amount of the granular filling 3 to be inserted into the mat 2 as conventionally performed. The advantage that does not require is obtained.

The filling rate of the granular filling in the mattress 1 in the state shown in FIG. 1 is set to a value smaller than an appropriate value in advance, and the granular filling 3 in the mat side 2 of the mat 1 is moved to the mat side. 2 by being moved toward one side edge 2b of the band 2 to be folded at a longitudinal fold 8 of the band 2 at an arbitrarily set portion of the space created near the other side 2b of the band 2. When in the state, it may be configured as an optimal mat for a sleeping person.

The mattress 1 shown in FIG. 6 (a) is used to remove the granular packing 3 from the mattress side 2 of the mattress 1 in order to obtain a mat with a desired filling ratio of the granular filling. By moving it toward one side edge 2b of the side 2 and at the position of the vertical fold 8 of the side 2 at an arbitrarily set portion of the space generated near the other side edge 2b of the side 2 Side 2
