Description

The present invention relates to heating cushions.

2. Description of the Related Art Conventionally, it is known to put warm water inside a cushion and use it as a heating device. Such a cushion is, for example, a crescent-shaped cushion in which a water supply sponge is inserted, and warm water is supplied from the water supply port and discharged from the discharge port to warm the sponge. It has been proposed (see Patent Document 1, for example).

Actual climbing No. 3051676

However, in the neck support mat of Patent Document 1, it is difficult for the warm water to impregnate the entire water-absorbing sponge, and as a result, the warm water does not spread all over the cushion.

The present invention is a heating cushion that allows hot water to spread throughout the cushion.

The present invention [1] includes a heating cushion comprising a bag for storing hot water and a plurality of hot water impregnated mats housed in the bag and stacked on top of each other.

In such heating cushions, a plurality of hot water impregnated mats are stacked on top of each other within the bag. Therefore, when hot water is put into the bag, the warm water is impregnated into each of the warm water-impregnated mats while flowing between the warm water-impregnated mats. Therefore, it is possible to distribute the hot water throughout.

The present invention [2] includes the heating cushion according to [1] above, wherein the bag has a shape with corners.

If the shape of the bag has corners, it is difficult to spread hot water around the corners. However, in the above-described heating cushion, since hot water flows between the hot water-impregnated mats, it is possible to reliably spread hot water even to the corners.

The present invention [3] includes the heating cushion according to [1] or [2] above, wherein the plurality of warm water-impregnated mats and the bags are locked to each other with strings.

When hot water is put into the bag or when the heating cushion is deformed during use, the hot water impregnated mats in the bag may be bent or the relative positions of the plurality of hot water impregnated mats may be displaced. However, in the above heating cushion, since the plurality of warm water-impregnated mats and the bags are locked to each other with strings, the hot water-impregnated mats are restrained from bending in the bags, and the relative arrangement between the warm water-impregnated mats is suppressed. Displacement can be suppressed. Furthermore, since the string allows the plurality of warm-water-impregnated mats and bags to be loosely locked, the hot-water flow path can be reliably secured.

The present invention [4] includes the heating cushion according to any one of [1] to [3] above, wherein the warm water impregnated mat is a non-woven mat.

In such a heating cushion, since the hot water-impregnated mat is a non-woven mat, it can be impregnated with hot water more efficiently than a water-absorbing sponge.

In the heating cushion of the present invention, a plurality of hot water impregnated mats are stacked on top of each other inside the bag. Therefore, when hot water is put into the bag, the warm water is impregnated into each of the warm water-impregnated mats while flowing between the warm water-impregnated mats. Therefore, it is possible to distribute the hot water throughout.

The bag body 21 is, for example, a flexible container made of water-resistant resin. The bag main body 21 is deformable in a state in which hot water is stored inside. More specifically, the bag main body 21 is formed by heat-sealing a plurality of (for example, two) sheets made of water-resistant resin by a known method (see broken line in FIG. 1). The sheet forming the upper surface of the bag body 21 is hereinafter referred to as an upper sheet 21a. A sheet forming the lower surface of the bag body 21 is called a lower sheet 21b. The bag body 21 is manufactured by stacking an upper sheet 21a and a lower sheet 21b and heat-sealing the peripheries thereof.

Examples of water-resistant resins include polyvinyl chloride resins, polyester resins, polyvinyl alcohol resins, polyolefin resins, polyurethane resins, polyacrylamide resins, epoxy resins, phenol resins, silicone resins, and fluorine resins. These can be used alone or in combination of two or more. As the water-resistant resin, polyvinyl chloride resin and polyester resin are preferably used. Moreover, the sheet of the water-resistant resin may be a single layer or a plurality of layers. Preferably, the water-resistant resin sheet has an inner layer of polyvinyl chloride resin on the inner surface of the bag 2 and an outer layer of polyester resin on the outer surface of the bag 2 . If the inner layer is a polyvinyl chloride resin, better water resistance can be obtained. Moreover, if the outer layer is made of a polyester resin, excellent tactile sensation can be obtained in addition to water resistance.

The thickness of the water-resistant resin sheet is, for example, 1 μm or more, preferably 10 μm or more. The thickness of the water-resistant resin sheet is, for example, 10 mm or less, preferably 1 mm or less.

The bag body 21 has a shape with corners. More specifically, the bag body 21 has a substantially rectangular parallelepiped shape with an inner cavity. The size of the bag main body 21 is not particularly limited, and is appropriately set according to the purpose and application.

For example, the length of the long side of the bag body 21 in plan view is, for example, 10 cm or more, preferably 20 cm or more. In addition, the length of the long side of the bag body 21 in plan view is, for example, 100 cm or less, preferably 80 cm or less.

In addition, the length of the short side of the bag body 21 in plan view is, for example, 5 cm or more, preferably 10 cm or more. In addition, the length of the short side of the bag body 21 in plan view is, for example, 80 cm or less, preferably 50 cm or less.

Moreover, the height (thickness) of the bag body 21 is, for example, 1 cm or more, preferably 3 cm or more. Also, the height (thickness) of the bag body 21 is, for example, 30 cm or less, preferably 10 cm or less.

An opening (not shown) is formed in the upper sheet 21b of the bag body 21 . An opening (not shown) allows hot water to be supplied to the bag body 21 and allows water to be discharged from the bag body 21 . The shape and size of the opening (not shown) are not particularly limited. The openings (not shown) are opened near the corners of the upper sheet 21a and have, for example, a circular shape. The opening (not shown) is closed by a water supply/drainage plug 22, which will be described later.

A fixing piece 25 is provided inside the bag body 21 . The fixed piece 25 is made of a small piece of the same kind of water-resistant resin as the bag body 21 . The fixed piece 25 has a hole through which the string 4 (described later) is inserted, although the details will be described later. The number of fixing pieces 25 is the same as the number of strings 4 (described later). More specifically, when four strings 4 are provided, four fixing pieces 25 are provided corresponding to the number and positions of strings 4 .

2 and 3, each fixed piece 25 is fixed to the lower sheet 21b inside the bag body 21. As shown in FIG. The size of each fixed piece 25 is not particularly limited, and is appropriately set according to the size of the bag body 21 and the warm water impregnated mat 3 .

The water supply/drain plug 22 is an open/close plug made of known resin. Examples of resins include the water-resistant resins described above. As shown in FIGS. 1 and 2, the water supply/drain plug 22 is provided on the upper surface of the upper sheet 21a so as to close an opening (not shown). That is, the water supply/drain plug 22 enables opening and closing of an opening (not shown).

One opening (not shown) and one water supply/drainage plug 22 are provided for one bag body 21 . As a result, hot water is injected into the bag body 21 or water is discharged from the bag body 21 through the opening (not shown). That is, the supply of hot water to the bag body 21 and the drainage from the bag body 21 are alternatives.

Moreover, the water supply/drainage plug 22 can have a valve mechanism if necessary. As a result, the water supply/drain plug 22 can suppress leakage of hot water from the bag body 21 .

A plurality of warm water-impregnated mats 3 are stacked on each other and housed in the bag body 21 . The number of hot water impregnated mats 3 is not particularly limited as long as it is two or more. 2 and 3, the number of hot water impregnated mats 3 is two.

The material of each hot water-impregnated mat 3 is not particularly limited as long as it can be impregnated with hot water. Each warm water impregnated mat 3 preferably consists of a non-woven mat.

Nonwoven mats are mats made of intertwined resinous fibers. Examples of resin fibers include polyester fibers, polyether fibers, polycarbonate fibers, polyurethane fibers and phenol resin fibers. Resin fibers preferably include polyester fibers and polyether fibers, and more preferably polyester fibers. The thickness of the resin fiber is not particularly limited, and is appropriately set according to the purpose and application.

Nonwoven mats are formed, for example, by thermocompressing and intertwining resin fibers in a known manner. The basis weight of the non-woven mat is not particularly limited, and is appropriately set according to the purpose and application.

The shape of each warm-water-impregnated mat 3 is not particularly limited as long as it can be accommodated in the bag body 21 . For example, the shape of the warm-water-impregnated mats 3 in a laminated state (laminate shape) may be the same as or similar to the internal shape of the bag body 21, or may be a shape different from the internal shape of the bag body 21. . Moreover, the size of the warm-water-impregnated mats 3 in a laminated state (laminate size) may be the same as or different from the internal size (capacity) of the bag body 21 . If these sizes are different, the size of the warm-water-impregnated mats 3 in the laminated state may be smaller or larger than the internal size of the bag body 21 . For example, the size of the warm-water-impregnated mat 3 in the laminated state is, for example, 0.8 times or more, preferably 0.9 times or more, and for example, 2 times or less, preferably the internal size of the bag body 21. , 1.5 times or less.

For example, the length of the long side of the warm water-impregnated mat 3 in plan view is, for example, 9 cm or more, preferably 15 cm or more. Further, the length of the long side of the warm water-impregnated mat 3 in plan view is, for example, 200 cm or less, preferably 150 cm or less.

In addition, the length of the short side of the warm-water-impregnated mat 3 in plan view is, for example, 4 cm or more, preferably 9 cm or more. In addition, the length of the short side of the warm water-impregnated mat 3 in plan view is, for example, 180 cm or less, preferably 150 cm or less.

Further, the height of each hot water impregnated mat 3 is appropriately set according to the number of hot water impregnated mats 3 .

More specifically, the height (thickness) of each warm water impregnated mat 3 is, for example, 0.5 cm or more, preferably 1.5 cm or more. Further, the height (thickness) of each hot water impregnated mat 3 is, for example, 50 cm or less, preferably 30 cm or less.

In the heating cushion 1 , a plurality of warm water impregnated mats 3 and bags 2 are locked together with strings 4 . More specifically, when a plurality of warm-water-impregnated mats 3 have a rectangular shape in plan view, four cords 4 are provided, for example. The material and size of the string 4 are not particularly limited, and are appropriately set according to the purpose and application.

As shown in FIGS. 2 and 3, each cord 4 is arranged at each of the four corners of the rectangular shape in plan view, and penetrates all of the laminated warm water-impregnated mats 3 at points A and B. . Points A and B are end points of a line segment along the diagonal direction in the plan view of the warm water impregnated mat 3 . The string 4 is inserted through the hole of the fixing piece 25 . In this state, each string 4 is tied in a loose ring shape.

More specifically, the string 4 is first passed through the hole of the fixed piece 25 . Next, at each of the four corners of the warm-water-impregnated mat 3 in plan view, the string 4 is inserted through the point A of the warm-water-impregnated mat 3 on the lower side. The string 4 is then passed through the point A of the upper warm water impregnated mat 3 . The string 4 is then passed through the upper hot water impregnated mat 3 at point B. As shown in FIG. The string 4 is then passed through the point B of the warm water impregnated mat 3 on the lower side. Furthermore, the string 4 is passed through the hole of the fixed piece 25 again as needed. Then, the string 4 is connected to the holes of the fixed pieces 25, the point A of the lower warm water impregnated mat 3, the point A of the upper warm water impregnated mat 3, the point B of the upper warm water impregnated mat 3, and the lower warm water. While the impregnated mat 3 is inserted through the point B, it is tied by any method.

As a result, the warm water-impregnated mat 3 and the bag body 21 which are laminated are locked by the string 4 . As a result, the relative positions of the hot water-impregnated mats 3 are loosely fixed by the cords 4 . Further, the relative positions of each hot water impregnated mat 3 and the bag body 21 are loosely fixed by the string 4 .

The material and size (thickness, length) of the cord 4 are not particularly limited, and are appropriately selected from natural fibers, synthetic fibers, etc., according to the purpose and application.

When the heating cushion 1 is used, first, the water supply/drain valve 22 is opened, and warm water is injected into the bag body 21 through the opening (not shown). After that, the water supply/drain valve 22 is closed. As a result, as shown in FIG. 4, the warm water is sealed in the bag body 21 and impregnated into the warm water-impregnated mat 3 . As a result, the bag main body 21 expands to increase the cushioning property, and the surface of the bag main body 21 is warmed by the hot water.

The amount of hot water supplied to the bag body 21 is not particularly limited as long as the bag body 21 can be inflated, and is appropriately set according to the size of the bag body 21 . More specifically, the amount of hot water supplied to the bag body 21 is, for example, 1 L or more, preferably 3 L or more, and for example, 20 L or less, preferably 10 L or less.

According to the heating cushion 1 as described above, the cushion can be heated by hot water while ensuring cushioning properties such as body pressure distribution, and the cushion can be used as a heating device. After use, the water supply/drain valve 22 is opened, and hot water or water (cooled hot water) is discharged from the bag body 21 through an opening (not shown).

Such a heating cushion 1 is suitably used, for example, as a head cushion, a shoulder cushion, a back cushion, and a drip cushion in head spas, barber/beauty salons and hospitals.

2. Action and Effect In the heating cushion 1 as described above, a plurality of hot water-impregnated mats 3 are laminated in the bag 2 . Therefore, when hot water is put into the bag 2, the hot water is impregnated into each of the hot water impregnated mats 3 while flowing between the plurality of hot water impregnated mats 3. - 特許庁Therefore, it is possible to distribute the hot water throughout.

More specifically, in the heating cushion 1 described above, the hot water flow occurs in the space X (see FIG. 2) between the top warm water impregnated mat 3 and the top sheet 21a. The hot water flow also occurs in the space Y (see FIG. 2) between the bottom hot water impregnated mat 3 and the lower sheet 21b. Furthermore, hot water flow occurs in the space Z (see FIG. 3) between the hot water impregnated mats 3 to be laminated.

That is, if a plurality of warm-water-impregnated mats 3 are stacked, a space Z is formed, and thus the space through which hot water flows increases compared to the case where the warm-water-impregnated mats 3 are not stacked. Therefore, it is possible to spread hot water over the entire heating cushion 1 .

In addition, if the bag 2 in the heating cushion 1 has a shape with corners, it is difficult to spread hot water around the corners. However, in the heating cushion 1 described above, since the hot water flows between the hot water-impregnated mats 3, it is possible to ensure that the hot water is evenly spread over the corners.

That is, if the hot water-impregnated mat 3 is not laminated, it is difficult to spread hot water around the corners of the heating cushion 1, so the bag 2 must be formed in a circular or semi-circular shape. On the other hand, if a plurality of hot water-impregnated mats 3 are laminated as described above, the number of paths through which hot water flows increases compared to the case where the hot water-impregnated mats 3 are not laminated. Therefore, it is possible to spread hot water over the entire heating cushion 1 . As a result, even if the bag 2 has a shape with corners (for example, a rectangular shape in plan view), it is possible to spread the hot water over the entire heating cushion 1 .

Furthermore, when hot water is put into the bag 2 or when the heating cushion 1 is deformed during use, there is a risk that the warm water impregnated mat 3 inside the bag 2 will be bent, and the relative arrangement between a plurality of warm water impregnated mats 3 Misalignment may occur. However, in the above heating cushion 1, since the plurality of warm water impregnated mats 3 and the bags 2 are locked to each other with strings 4, the warm water impregnated mats 3 in the bags 2 are restrained from bending, and the warm water impregnated mats 3 are prevented from bending. A shift in the relative arrangement between the mats 3 can be suppressed. Furthermore, according to the string 4, since the plurality of warm water-impregnated mats 3 and the bags 2 can be loosely locked, the hot water flow path can be reliably secured.

That is, if the plurality of warm-water-impregnated mats 3 and the bags 2 are not locked to each other by the string 4, the hot water stays in the bags 2, causing the relative positions of the plurality of warm-water-impregnated mats 3 and the bags 2 to shift. may occur. On the other hand, if a plurality of warm water-impregnated mats 3 and bags 2 are locked to each other with strings 4, the relative positional deviation of the plurality of warm water-impregnated mats 3 and bags 2 can be suppressed, and maintainability can be improved. can be planned.

In addition, in the heating cushion 1 described above, since the warm water-impregnated mat 3 is a non-woven mat, it can be impregnated with hot water more efficiently than a water-absorbing sponge.

That is, if the warm water-impregnated mat 3 is a non-woven mat, it is possible to spread the warm water over the entire surface compared to the case where the warm water-impregnated mat 3 is sponge or the like.

3. Modifications In the heating cushion 1 described above, the bag 2 and the warm water-impregnated mat 3 have a substantially rectangular shape in plan view, but the shapes of the bag 2 and the warm water-impregnated mat 3 are not limited to the above. As for the planar shape of the bag 2 and the warm-water-impregnated mat 3, examples of shapes having corners include square, triangle, pentagon, hexagon, and other polygonal shapes. Moreover, as for the planar view shape of the bag 2 and the warm water-impregnated mat 3, shapes having corners include, for example, a half-moon shape, a crescent shape, and an arbitrary character shape. Further, the shape of the bag 2 and the warm-water-impregnated mat 3 in a plan view includes a shape having no corners, more specifically, a disk shape and a spherical shape.

In the heating cushion 1 described above, a non-woven fabric mat is used as the warm water-impregnated mat 3, but the warm water-impregnated mat 3 is not limited to the above. The warm water impregnated mat 3 includes, for example, a woven mat and a sponge.

In the heating cushion 1 described above, the bag 2 and each warm water-impregnated mat 3 are locked by the string 4. It does not have to be locked. Also, for example, the string 4 may not be used, and neither the bag 2 nor the warm water-impregnated mats 3 may be locked.

Moreover, although the heating cushion 1 described above has one water supply/drainage plug 22 , it may have two water supply/drainage plugs 22 . In such a case, for example, hot water may be supplied from one water supply/drainage plug 22 and water may be discharged from the other water supply/drainage valve 22 at the same time. In addition, the heating cushion 1 may be provided with an opening and an air plug as air vents separately from the water supply/drain plug 22 .
