Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a water mattress (including a water bed mat) using water as a cushioning material.

Conventionally, a water mattress is generally made by injecting water into one bag formed in the shape of a mattress. In this case, the thickness is 5 cm, the length is 195 cm, and the width is 120 cm, and the volume is 5 × 195 × 120 = 1117, so when water is put in, it weighs about 117 kg, which is very heavy. It is not possible to inject and assemble water at the factory, and normally, skilled professionals use special equipment to inject water at the place of use.

Further, since it is very heavy, it is almost impossible to move it, and even if the arrangement is changed, it is necessary to ask a professional job, which is very complicated.

Further, there is a problem that durability against such a large weight is required, which is inevitably expensive.

[0007] Therefore, recently, there has been proposed one in which a plurality of bags each having a structure in which a mat is divided into a plurality of box-shaped bodies are juxtaposed and used. However, a plurality of box-shaped water mattress constituent elements are arranged. Has a big problem that the vertical member of the bag divided into small parts gives a feeling of discomfort to the user's back and the movement range of water is limited, so that the feeling of use as a water mattress cannot be obtained. It was

Also, it was assumed that the strength of the water mattress would be improved by reducing the size of the water mattress component. However, since the load is actually concentrated when weight is applied, there is almost no advantage in improving the durability by reducing the size. It has been found.

[0007]

[Problems to be solved by the device]

 Therefore, the present invention divides the water mattress components so that the user can assemble and transport them, has sufficient strength, and does not impair the usability as a water mattress. The challenge is to provide a mattress.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the structure of the present invention has a check valve 21 and a sealing lid 22 at appropriate positions of a synthetic resin cylindrical bag 10 having a length substantially matched with the width direction of the mattress. The water injection port 20 is provided, water is injected into the synthetic resin cylindrical bag 10 and the water injection port 20 is sealed, and a plurality of the water injection ports 20 are arranged in the mattress cover 30 with their longitudinal directions oriented in the width direction of the mattress. It is a technical measure that has been taken.

Therefore, the water mattress of the present invention uses the synthetic resin cylindrical bag 10 having a length substantially matched to the width direction of the mattress, so that the water mattress has a function of ensuring a large strength. . In other words, if a synthetic resin tube is used as the synthetic resin cylindrical bag 10, water can be injected and sealed by attaching circular lids (usually welding) to both ends of the tube. Therefore, the number of fixed parts that are apt to be damaged is reduced, and it becomes more difficult to damage. Further, since this fixing portion has a circular linear shape, it does not have a load concentration portion where three corners are gathered unlike a box-shaped body, and can withstand a large load.

For example, assuming that each synthetic resin cylindrical bag 10 has a diameter of 14 cm and a length of 175 cm, the volume is 7 × 7 × π × 110≈16925, and if 80% of this volume is filled with water, 16925 x 0.8 ≈ 13540 is about 13.5 Kg, which is a weight that can be easily transported by ordinary people, so that the user himself can inject water to assemble or rearrange.

When the diameter of the synthetic resin cylindrical bag 10 is set to 14 cm, when it is placed on the floor, the cross section tends to become an ellipse due to the weight of water. Instead of arranging them at intervals, 8 to 10 pieces are arranged so that the lengthwise dimension of the mattress is about 19 to 200 cm. Then, the upper surfaces on which the synthetic resin cylindrical bags 10, 10, 10, ... Are pressed against each other to form a flat surface except for the peripheral portion although they have some irregularities.

Further, the water mattress of the invention of "Claim 2" is tightly closed with the check valve 21 at a proper position of the synthetic resin cylindrical bag 10 having a length substantially matched with the width direction of the mattress.

The technical means was adopted in which a plurality of the water outlets 20 that were sealed were arranged in the mattress cover 30 with the longitudinal direction thereof oriented in the mattress width direction.

Therefore, in the water mattress of the present invention, in addition to the above-mentioned action, since the scale 11 indicating the water injection amount is provided on the peripheral surface of the synthetic resin cylindrical bag 10, the water injection amount is reduced. Has a recognizable effect. For example, to harden the waist, add a lot of water to the synthetic resin cylindrical bag 10 for that part, and conversely, add a small amount of water to soften it a little to adjust the hardness and fluidity. It has a possible effect.

Further, in the invention of “claim 3”, the check valve 21 is provided at an appropriate position of the synthetic resin cylindrical bag 10 having a length substantially matched with the width direction of the mattress and having a diameter of about 10 to 20 cm. And a sealing lid 22 are provided, and a scale 11 indicating the amount of water injected is provided on the peripheral surface of the synthetic resin cylindrical bag 10. The synthetic resin cylindrical bag 10 is filled with water. A technique in which approximately 60 to 90% of the capacity of the cylindrical bag 10 is injected and the water injection port 20 is sealed, and a plurality of them are arranged in the mattress cover 30 by arranging them in the longitudinal direction of the mattress width direction. It is a measure that has been taken.

Therefore, the water mattress of the present invention is convenient to handle because the diameter of the synthetic resin cylindrical bag 10 is about 10 to 20 cm in addition to the above-mentioned action, and the synthetic resin cylindrical bag 10 As a result of the experiment, it was confirmed that by injecting about 60 to 90% of the volume of the water, the effect of maintaining the feeling of use as a water mattress is exhibited.

Also, The water mattress of the invention of "Claim 4" is a water injection port having a check valve 21 and a sealing lid 22 at an appropriate position of a cylindrical back 10 made of synthetic resin, which is substantially matched with the width direction of the mattress. 20 is provided, and a plurality of water-injecting water is injected into the synthetic resin cylindrical bag 10 and the water injection port 20 is sealed in a box-shaped waterproof sheet body 40 having an opening at the top, the longitudinal direction of which is the mattress width direction.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 10 is a synthetic resin cylindrical bag 10 having a length substantially matched with the width direction of the mattress, and a water injection port 20 having a check valve 21 and a sealing lid 22 is provided at an appropriate position. There is.

The synthetic resin cylindrical bag 10 may be made of vinyl chloride, which is generally used in this type, but of course, other synthetic resin materials may be used. The synthetic resin cylindrical bag 10 may be formed by rolling a sheet material into a tubular shape and welding the joining edges and welding circular sheets to both ends thereof. In the present embodiment, the synthetic resin cylindrical bag 10 is made of synthetic resin having a predetermined diameter in advance. A tube is prepared, and this synthetic resin tube is cut into a predetermined size to form a main body 10a (see FIG. 3), and circular sheet materials 10b and 10b (lower end in FIG. 3) separately prepared at both ends thereof. The sheet material 10b is also arranged at the side extension tip.) Is welded at the overlapping edge portion thereof (using a conventionally known device of a high-frequency welder device).

The water injection port 20 is made of a material (for example, polyethylene) that can be welded to the synthetic resin cylindrical bag 10, and the cylindrical main body 20 a with the flange 20 b is attached to the synthetic resin cylindrical bag 10. It is inserted into a through hole (in the illustrated example, the through hole is provided in a circular sheet material 10b in the figure) and is welded and fixed to the synthetic resin cylindrical back 10 at its flange portion 20b. .

The check valve 21 is formed of a wing-shaped inner lid (integrally molded and has flexibility) which is partially continuous with the lower end of the main body 20a. It is configured to be closed by (water pressure in the synthetic resin cylindrical bag 10), and when water is injected, the check valve 21 is bent into the synthetic resin cylindrical bag 10. Further, the sealing lid 22 is constituted by a fitting lid in the illustrated embodiment, and is connected to the main body 20a by the connecting portion 20c and the picking portion 20d. However, of course, the sealing water inlet 20 can be sealed. Of course, it may be replaced with a screw lid.

Then, a plurality of synthetic resin cylindrical bags 10 into which water has been injected to seal the water injection port 20 are arranged with their longitudinal directions oriented in the width direction of the mattress.

When injecting water into the synthetic resin cylindrical bag 10, it is preferable to mix a predetermined amount of preservative, and it is also possible to mix an antibacterial property in the material itself of the synthetic resin cylindrical bag 10. . Further, as described above, the amount of water poured into the synthetic resin cylindrical bag 10 is appropriately adjusted, and the amount of water injected is most preferably about 60 to 90% of the capacity of the synthetic resin cylindrical bag 10. As a result of the test, it turned out to be a thing.

The synthetic resin cylindrical bag 10 in which the water is injected has a plurality of sealed water injection ports 20, and a plurality of such bags are arranged with their longitudinal directions oriented in the width direction of the mattress. When arranging the synthetic resin cylindrical bags 10, 10, 10 ..., Of course, it is not necessary to prevent a gap from being formed between the adjacent synthetic resin cylindrical bags 10. When the bag 10 is placed on the floor, it has an oblong cross section that tends to become flattened by the gravity of water, but it is pushed by the other synthetic resin cylindrical bags 10 from both sides and the cross section is approximately rectangular. It is advisable to make them close to each other so as to form a rectangular shape.

If the synthetic resin cylindrical bags 10, 10, 10 ... Are simply arranged side by side, each of them will move at random when riding on them, so store them in the mattress cover 30. Become.

It is the same as "Claim 1" that the water injection port 20 provided is provided.

Further, in the present invention, a scale 11 indicating the amount of water injected is provided on the peripheral surface of the synthetic resin cylindrical bag 10. This scale 11 indicates the ratio of the volume of the synthetic resin cylindrical bag 10 to the volume of the injection water level. In the illustrated embodiment, as shown in FIG. The water level line of 60 to 90% is displayed every 5%, and the numerical value is attached to each display line.

Further, water is injected into the synthetic resin cylindrical bag 10 to seal the water injection port 20, and a plurality of those are arranged in the mattress cover 30 by arranging a plurality of them in the longitudinal direction of the mattress width direction. What is done is the same as that of "Claim 1".

Next, in the invention of “claim 3”, a check valve 21 is provided at an appropriate position of the synthetic resin cylindrical bag 10 having a length substantially corresponding to the width direction of the mattress and having a diameter of about 10 to 20 cm. A water injection port 20 having a cover 22 and a close lid 22 is provided.

That is, since the diameter of the synthetic resin cylindrical bag 10 is limited to about 10 to 20 cm, the reason for doing this is firstly a matter of weight, which is 20 to 30 kg which is easy for an ordinary person to carry. This is because Another reason is to make the volume as large as possible so as not to impede the fluidity of water.

The scale 11 for indicating the amount of water to be injected is provided on the peripheral surface of the synthetic resin cylindrical bag 10 as in “claim 2”.

In addition, according to the present invention, the synthetic resin cylindrical bag 10 is filled with water in an amount of about 60 to 90% of the capacity of the synthetic resin cylindrical bag 10 and the water injection port 20 is sealed. Are arranged in the mattress cover 30 with their longitudinal directions oriented in the width direction of the mattress.

That is, it was confirmed by an experiment that water is not injected until the volume of the synthetic resin cylindrical bag 10 is completely filled, but the water injection amount of 60 to 90% is good, and is about 70 to 75%. The same feel as the water mattress of the above can be obtained, and if there is less water than that, it will have a feeling of fluidity and a soft feeling, and if more water is added, the feeling of fluidity will be less and the feeling will be hard. Good. An adjustment method such as changing the amount of water in the synthetic resin cylindrical bag 10 at a specific place on the head or waist to obtain an overall balance is also suitable.

Next, in the invention of “claim 4”, a check valve 21 and a sealing lid 22 are provided at appropriate positions of the synthetic resin cylindrical bag 10 which is substantially aligned with the width direction of the mattress. The provision of the water port 20 is the same as in "Claim 1" and "Claim 2".

According to the present invention, a plurality of water-injecting water is injected into the synthetic resin cylindrical bag 10 and the water injection port 20 is sealed in a box-like waterproof sheet body 40 having an opening at the top in the longitudinal direction. Stored side by side in the width direction of the mattress, the foamed synthetic resin material bodies 50, 50, 50 ...

Are housed in the mattress cover 30.

That is, the synthetic resin cylindrical bags 10, 10, 10 ... Are not stored directly in the mattress cover 30, but first the synthetic resin cylindrical bags 10, 10, 10 ,. It is housed in a box-shaped waterproof sheet body 40 having an opening. The waterproof sheet 40 is made of a synthetic resin sheet to prevent water leakage in the unlikely event.

Further, the foamed synthetic resin material bodies 50, 50, 50 ... Maintain the overall shape retention while guaranteeing appropriate deformability of the synthetic resin cylindrical bags 10, 10, 10. In addition to being improved, it prevents heavy water from entering areas that are not normally used, and is designed to maintain a well-formed appearance and to be lightweight. The foam synthetic resin material body 50 is selected to have appropriate cushioning properties. In addition, it goes without saying that this foamed synthetic resin material body 50 may be a chip-shaped one housed in a bag.

Next, in the invention of “claim 5”, a check valve 21 and a sealing lid 22 are provided at appropriate positions of the synthetic resin cylindrical bag 10 substantially matched with the width direction of the mattress. The water outlet 20 is provided as described above.

The scale 11 for indicating the amount of water to be injected is provided on the peripheral surface of the synthetic resin cylindrical bag 10 as in “claim 3”.

Then, in a box-shaped waterproof sheet body 40 having an opening at the top, water is injected into the synthetic resin cylindrical back 10 and the water injection port 20 is sealed. The side walls of the waterproof sheet body 40 are arranged side by side, and the foamed synthetic resin material bodies 50, 50, 50, ... An electric heater 60 is interposed between the synthetic resin material body 50 and the synthetic resin cylindrical bag 10, 10, 10, ..., Waterproof sheet body 40, synthetic resin material body 50, 50, 50 ... The electric heater 60 and the electric heater 60 are housed in the mattress cover 30.

That is, the present invention includes the electric heater 60 in addition to the configuration of “claim 4”. The main purpose of this electric heater 60 is to prevent the synthetic resin cylindrical bag 10 from hardening in winter and cold regions, and it is sufficient to use a heater capable of keeping the temperature at about 10 ° C. There is no problem even if it is used for heat retention.

The electric heater 60 may have various conventionally known structures, but the electrodes 62 and 62 are laminated at a predetermined interval on the resistance material film 61, which is applied to floor heating or the like, and the heat resistant film 63 is formed. By using a so-called sheet heating element covered with, the predetermined temperature can be secured without using the controller 64, and the configuration is simple. In addition, it is known that this seed heating element is highly waterproof and exhibits high safety even when used near water (used to prevent freezing of water pipes, etc.). It is easy to maintain the set temperature of this seed heating element, but it is difficult to adjust the temperature. Therefore, in order to set the temperature desired by the user, it is necessary to adjust the energizing amount with the controller 64. Of course it is used.
