Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress which has a basic structure in which a filling material is provided between a front cloth and a back cloth, and which is particularly excellent in immediate temperature performance and heat retention performance.

[0002]

2. Description of the Related Art As elements required for comforters, mattresses, etc., there are heat retention, moisture release and sleeping comfort. Conventionally, as to the heat retaining property of the comforter, a quilt is improved by a sewing method such as a three-dimensional quilt or a dome quilt in order to secure an air layer, or a warm air blown type in which an air introducing member is incorporated (Actual Kaihei 5-36983 ) Is proposed.

On the other hand, the mattress has a basic structure different from that of the comforter due to a functional difference (heating from the back side of the body). Therefore, with respect to its heat retaining property, improvement and development of the material of the cloth and the filling material Stays in. That is, a method of increasing the air content by mixing natural materials such as wool, feathers and cotton with chemical materials such as polyester / acrylic, or heat-insulating, radiating, and infrared action by incorporating a coating material of aluminum / ceramic fine powder. The method of improving the heat retention is adopted.

[0004]

However, according to the above-mentioned conventional method, the heat source for heat retention is not the material but the one dependent on the cage heat due to the body temperature. In addition, it is not possible to quickly raise the interior of the comforter to a suitable temperature (immediate temperature), and it is difficult to expect comfort in terms of the temperature when falling asleep, especially in winter.

A method of heating the interior of the mattress by applying the principle of the futon dryer is also conceivable. In this method, an air bag (sheets) provided to retain the warm air blown therein is provided with an air permeability of An extremely low material (nylon taffeta fiber, etc.) must be adopted, and it is inappropriate for raising the inside of the mattress quickly and easily.

The present invention has been made in view of the above,
It is an object of the present invention to provide a mattress that has a structure for introducing warm air inside and uses a heat storage layer structure to simultaneously realize immediate temperature retention and heat retention.

[0007]

According to the present invention, there is provided one blower which communicates with the outside between two layers of middle cloth arranged inside from the front cloth through the filler and the back cloth through the heat insulation layer material. A mattress having an inner space portion having a mouth formed and being sewn at the periphery thereof, wherein the middle cloth is made of a material having a high air permeability and a mesh having a size equal to or smaller than that of the filling material, The front fabric is made of a material having an air permeability equal to or lower than the middle fabric, the back fabric is made of a material having an air permeability equal to or lower than the front fabric, and the filling material is made of a material having a high moisture releasing property, and is kept warm. The layer material is made of a slightly hard heat storage material (Claim 1).

Further, according to the present invention, a filling material is provided between the backing material and the heat insulating layer material (claim 2).

Further, the heat insulating layer material may be a hard cotton formed by compressing a cotton material into a plate shape (claim 3).

Further, it is preferable that the blower port is provided on a foot side (claim 4).

According to the present invention, the upper part of the futon consisting of the front cloth and the upper middle cloth, and the lower part of the futon consisting of the lower middle cloth and the back cloth are sewn together, and the upper part of the futon is formed. The lower part of the futon is connected to the lower part of the futon by a gusset (claim 5).

Further, it is preferable that the blower port is formed in the gusset (claim 6).

Further, the gusset connects the first gusset of the portion forming the blast opening, the upper part of the futon and the lower part of the quilt at the periphery thereof, and at least the blowing opening of the first gusset. It is preferably composed of a second gusset with a part removed (claim 7).

[0014]

According to the first aspect of the present invention, when the warm air is discharged from the blower opening, the inner space portion swells due to the wind pressure, and the inner space portion is formed by stitching around the futon. As a result, the warm air blown in is efficiently blown through the inner space part from the air outlet toward the back, and easily penetrates into the upper middle fabric. The infiltrated warm air is accumulated in the layer of the filling material because it is shielded to some extent by the surface material having an air permeability of not more than the medium material, and as a result, the layer of the filling material is inflated and the heat retaining portion is formed. Reserved. On the other hand, the warm air that travels in the inner space penetrates into the heat retaining layer material that has a certain layer thickness, and the heat is stored between it and the backing material, so the heat retaining and heat retaining effect of the heat retaining layer material is demonstrated. To be done.

After the blowing of warm air, the heat of the heat retaining layer is difficult to escape from the backing material, and due to the nature of the heat that moves upward, it is gradually radiated to the filling material, so the front material side is relatively long. The temperature is maintained at a preferable temperature for a time.

According to the second aspect of the present invention, by filling the space between the lining material and the heat insulating layer material with a filling material, it is possible to prevent the stored heat of the heat insulating layer material from radiating directly from the lining material to the floor or tatami mat.

According to the third aspect of the invention, since the hard cotton is formed in a plate shape, a desired hardness can be obtained for the body and a high heat storage property can be obtained.

According to the fourth aspect of the present invention, since warm air is blown from the foot side, a temperature distribution suitable for head cold foot heat can be easily obtained.

According to the fifth aspect of the present invention, since the upper part of the futon and the lower part of the futon are manufactured and then these are sewn together through the gusset and connected, the manufacturing can be easily performed.

According to the sixth aspect of the invention, since the blower port is formed in the gore, it is not necessary to use a special member for the blower port.

According to the seventh aspect of the invention, since the first gore on which the blower port is formed is provided as a separate body, it is possible to sew the second gore after the first goose is sewn. If so, the operation of suturing the gore can be easily performed as a whole.

FIG. 1 is a partially sectional perspective view of a mattress according to the present invention, and FIG. 2 is a partially enlarged sectional view taken along the line AA of FIG. . The mattress 1 is composed of a mattress upper portion 10 and a mattress lower portion 20, and an inner space portion 3 as a warm air passage for guiding the warm air therein is formed between them.

The upper part 10 of the futon has the same size of the front cloth 11 and the middle cloth 12, and the filling 1 between the front cloth 11 and the middle cloth 12.
3 is installed inside. And the table cloth 11
In the middle cloth 12, a desired position, for example, a position inside from the entire circumference of the end by a required size is sewn, and the inner part is sewn so as to intersect with a plurality of straight lines (see FIG. 1). A quilt 14 is formed, which effectively prevents the filled packing from moving and being unevenly distributed.

On the other hand, the lower part of the futon 20 is a medium cloth 2 of the same size.
1 and the back cloth 22, and between the inner cloth 21 and the back cloth 22, a plate-shaped heat retaining layer material 23 having a required thickness is provided. In addition, a structure in which a filling material 24 is provided between the heat insulating layer material 23 and the backing material 22 can be adopted depending on the necessity or the application. Although not shown in the figure, a quilt is also formed by stitching the middle cloth 21 to the back cloth 22 at required positions, and thereby the heat insulating layer material 23 and the filling material 2 are formed.
4 is not unevenly distributed or misaligned.

Each of the above members is made of the following materials. The middle fabrics 12 and 21 have particularly excellent air permeability (90% or more is particularly preferable), and the fillers 13 and 24
Is a material having a fine mesh that does not enter into the inner space 3, such as gauze.

The outer fabric 11 is a material having a lower air permeability than the middle fabrics 12, 21 and preferably having an air permeability of about 50% or more, such as cotton satin.

The heat insulating layer material 23 is formed from the inner space portion 3 to the inner cloth 21.
While allowing warm air to pass through to retain heat and store it, a material with an appropriate hardness that produces good sleeping comfort, such as polyester hard cotton, wool felt or hard polyurethane, is formed or compressed into a plate shape. , For example 1
It has a required thickness of about 2 cm and is formed in a plate shape.

The backing material 22 is a material having a relatively low or fairly low air permeability, such as a synthetic fiber or a down proof processed fiber which is surface-crushed after knitting. Alternatively, a material having a fine mesh or a knitting method may be used.

The fillers 13 and 24 are made of a material excellent in moisture release,
For example, wool, feather, wool or polyester cotton. Feather, which is lightweight and has a high heat retention property, is suitable as the filler 13 in the upper part 10 of the futon.

The upper part 10 of the comforter and the lower part 20 of the comforter are connected at their entire circumferences through the band-shaped gussets 4 having a required width. As shown in detail in FIG.
And the edge of the inner cloth 12 and the upper side of the gusset 4 are aligned and overlapped with each other, and this portion is covered with a belt-like cover member 15 along the periphery and sewn together as one piece between the upper and lower parts. Then, the ends of the inner cloth 21 and the back cloth 22 and the lower side of the gusset 4 are aligned and overlapped, and this portion is covered with a belt-like cover member 25 along the periphery and integrally sewed up and down. . In this way, the upper part 10 of the comforter and the lower part 20 of the comforter can be sewn separately at the respective end portions, which facilitates the work. The gusset 4 is the upper part of the futon 1 when warm air is blown, as described later.
A suitable inner space portion 3 is easily formed between 0 and the lower part of the futon, while it has a width of, for example, about 3 to 6 cm, which is almost equal to the thickness of the mattress so as to be normally closed. . In addition, in the lower part of the futon 20, the cover member 25
In this case, the heat insulating layer material 23 may be superposed and sewn together, and by doing so, the positional deviation of the heat insulating layer material 23 can be prevented.

Further, as shown in FIG. 1, the gore 4 is a mattress 1
A blow-in port 40 is formed at a substantially central position on the side that is the foot of the, and is cut by a required diameter or a predetermined length in the lateral direction. The blow-in port 40 communicates with the inner space 3. Further, the gusset 4 is composed of a partial gusset part 41 including a part where the blow-in port 40 is formed and a peripheral gusset part 42 covering the entire circumference of the mattress, and is configured such that the boundary part thereof partially overlaps. ing. By thus providing the partial gore portion 41 having the blowing port 40 as a separate body, the work of suturing the gore 4 can be performed separately, so that the work of suturing the gore 4 as a whole becomes easy.

Reference numeral 5 denotes a warm air heater (heater) as an external heat source.
Then, hot air having a required temperature of 50 ° C. or higher and up to about 70 ° C. is generated and blown out from the tip thereof through the tubular portion 51. The tubular portion 51 has a diameter approximately the same as the opening when the blow-in port 40 is widened, so that the warm air blown by this does not leak from the blow-in port 40 and does not easily escape by wind pressure. It has become.

Next, the operation of the mattress 1 will be described. The tubular portion 51 of the warm air blower 5 is inserted into the blowing port 40 to operate the warm air blower 5. Inner space 3 from the blow port 40
The warm air of 50 to 70 ° C. discharged to the side is blown from the foot side toward the left and right and the head side while slightly expanding the inner space portion 3 by the wind pressure. Since the inner space 3 does not have a partition up to the end of the futon, the blown warm air can efficiently spread to every corner, and the temperature can be rapidly increased and evened. While keeping the warm air in the inner space 3, the warm air easily penetrates the inner fabric 12 and enters the space in which the filling 13 is stored. On the other hand, since the air permeability of the outer fabric 11 is less than that of the middle fabric 12, the space in the storage space for the filling material 13 (50%)
About) The cage expands to form a heat retaining space. In addition,
Since the air permeability of the table cloth 11 is set to 50% or more, the warm air that has escaped from the table cloth 11 is caged in the upper comforter (not shown) to raise the comforter itself to an appropriate temperature. Will be made.

Further, a part of the warm air in the inner space portion 3 permeates the inner cloth 21, enters the heat retaining layer material 23, and is retained there. The heat staying in the heat insulating layer material 23 is higher because the heat dissipation to the floor or tatami side is hindered by the presence of the backing material 22 having a low air permeability and the filling material 24 interposed as necessary under the heat insulation layer material 23. A heat storage effect can be expected. This state is kept for a required time, for example, for about 10 to 30 minutes, or for a required time longer than that (in particular, depending on the temperature of the heat source and the blowing amount) to raise the internal temperature to preferably about 40 to 50 ° C. While pulling out the tubular portion 51 from the blowing port 40,
Turn off the hot air blower 5.

When the supply of warm air from the blowing port 40 is stopped, the air in the inner space 3 gradually contracts as it passes through the inner fabrics 12, 21 little by little. On the other hand, the storage space of the filler 13 which has been expanded once is in a state of being expanded and exerts a heat retaining effect, and is also in a state where sufficient heat is stored in the heat retaining layer material 23. Therefore, after the supply of hot air is stopped, 15 to 3
Even after a long time of 0 minutes, the mattress 1 shows a sufficiently high temperature and maintains a uniform temperature distribution. In particular, since the blowing port 40 is provided on the foot side, the temperature on the foot side is slightly higher than that on the head side, so it is possible to obtain a so-called cold head and foot heat, which is an optimum temperature distribution for human health during sleep. .

FIG. 4 is a chart showing changes in temperature rise due to operation of the hot air blower, and FIG. 5 is a chart showing changes in the heat retention state after the hot air blower is stopped. Note that FIG. 3 is a diagram showing the arrangement position of the thermometer in the temperature measurement. For temperature measurement,
The width direction is divided into four, and it is performed at a total of 5 places, 1/4 from the bottom side, 1/4 left and right positions, at the center position, and 1/4 from the head side, 1/4 positions left and right ing. The measurement time was 60 minutes after the hot air fan was operated, and only 60 minutes after the operation was stopped. Room temperature is 10 ° C. and humidity is 50%.

As shown in FIG. 4, the temperature rise is approximately 10
20 minutes higher than room temperature (10.5 ℃) in 2 minutes
After the lapse of 0 minutes, the temperature has risen to almost the required temperature and shows high immediate temperature. In 20 to 30 minutes, the temperature rises by several degrees. Also, when the foot side and the head side are the foot side, when observing after 30 minutes,
The temperature is about 1 ° C. higher, and the central position shows an intermediate temperature between the two. Moreover, by obtaining such high temperature,
Since the inside of the mattress 1 can be dehumidified and dried, mite extermination,
Hygienic effects such as bacterial killing can be obtained.

As shown in FIG. 5, at 20 minutes after the operation of the hot air blower 5 was stopped, the whole temperature was maintained at 30 ° C. (3 times the room temperature), indicating sufficient heat retention. Especially 60
Even after the lapse of minutes, the whole temperature was maintained at 20 ° C. (twice as high as room temperature) or higher, which shows that it has high heat retention.
