[0001]

The present invention relates to a cushion which can be used for watching sports (soccer, baseball, tennis, etc.) and leisure (hiking, fishing, etc.), and can be used indoors as a seat, backrest, etc. And a cushion with a heating element and a warming method using the same.

[0002]

BACKGROUND OF THE INVENTION Watching sports outdoors, especially in winter,
When enjoying leisure, etc., it is not easy to concentrate on watching sports, leisure, etc. because it is too cold, and since outdoor seats are often made of concrete or synthetic resin, it is painful to sit for a long time. It was accompanied. In order to solve this problem, a disposable body warmer, which is a general-purpose product, is simply made to be approximately the size of the user's buttocks, and a seat cushion with a thin sponge inside is conventionally used.

[0003]

However, the seat cushion cannot be used repeatedly and is uneconomical. In addition, when used, the water contained in the warmer evaporates, moistening the buttocks of the user with steam, and causing a discomfort.

[0004] The iron powder or the like filled in the interior is unevenly distributed, and the sitting comfort is poor.

[0005] In addition, there is a problem that, if directly laid, a burn may be caused, and there is a danger in use.

[0006] Further, the temperature rises rapidly, which makes it difficult to lay directly, and it may be necessary to wrap it with a cloth or the like before use.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to make a heating element detachable so that it can be used repeatedly instead of being disposable, and only to have a cushioning property. The cushion and heating element are used to improve air circulation, maintain an appropriate temperature state, do not cause discomfort to the user, and are used for various applications when a heating element is not used. It is to provide a cushion and a warming method using the cushion.

[0008]

In order to solve the above-mentioned problems, the present invention provides a surface material having a soft foam material as a core material inside; and a soft foam material inside a soft material on the back surface of the surface material. A backing material comprising a plurality of backing pieces as a material, at least two adjacent backing pieces are overlapped to form an opening between two overlapping ends, and the front face material and the backing material are opened. Were fixed to each other at their outer peripheral ends to form a cushion provided with a housing portion inside.

Next, a surface material having a soft foam material as a core material therein; and a back material comprising a plurality of back pieces on the back surface of the surface material and having a soft foam material as a core material therein. At least two adjacent back end pieces are superposed on each other to form an opening between the two superposed ends, and the outer peripheral ends of the front surface material and the rear surface material are fixed to each other. A heat-generating cushion with a heat-generating body is provided, wherein a heat-generating body that generates heat by introducing oxygen into the housing portion is detachably provided.

[0010] Then, the outer peripheral edges of the front surface material and the back surface material are thermally fused to each other. Therefore, the front surface material and the back surface material can be attached in a short time.

Next, through holes are formed at appropriate locations on the side edges of the outer peripheral edges of the front and rear members. Thereby, it becomes a new air supply hole and a new air discharge hole different from the opening.

Further, a soft foam material is interposed between the front sheet material and the inner sheet material as the surface material, and the entire outer peripheral edges of the front sheet material and the inner sheet material are heat-sealed. A soft foam material is interposed between the back sheet material and the inner sheet material, and the outer peripheral edge of the back sheet material and the inner sheet material is heat-sealed all around to be used.

Further, a number of ventilation holes are formed in the inner sheet material. Then, the air taken in from the through-hole spreads to every corner in the housing portion.

A soft vinyl chloride resin is used as the front sheet material, the back sheet material, and the inner sheet material. Therefore, it becomes easy to perform heat fusion.

Further, as a soft foam material, the thickness is 10 mm.
Use the above. By doing so, the step of the opening can be increased, and the elasticity can be improved.

In addition, a handle is attached to a proper fastening portion where the outer peripheral ends of the front surface material and the back surface material are fastened to each other. Therefore, it can also be used as a handbag.

A surface material having a soft foam material as a core therein, and a back material comprising a plurality of back pieces on a back surface of the surface material and having a soft foam material therein as a core material. An opening is formed between two overlapping ends by overlapping adjacent ends of at least two back pieces, and the outer peripheral ends of the front material and the back material are fixed to each other, and a housing portion is provided inside. The air taken in from the opening of the cushion is accommodated in the accommodating portion, and absorbed by the soft foam material, and the air absorbed by the soft foam material by the movement of the center of gravity of the user passes through the air hole provided in the inner sheet material. The present invention proposes a warming method using a cushion with a heating element, characterized in that fresh air is supplied into the housing portion and fresh air is supplied, and the air is similarly discharged from a stepped opening.

[0018]

According to the present invention, the cushion according to the present invention can be used indoors or outdoors, and at least two openings are formed by overlapping adjacent ends of two back pieces. In the case where the outer peripheral edge of the front surface material and the outer peripheral material of the back surface material are fastened to each other and an accommodating portion is provided therein, since the opening has a step, it does not completely adhere to the laying surface. Therefore, even if the user slightly shifts the center of gravity right and left, the user tilts left and right to generate a gap. Therefore, air can be taken in from the opening.

In the case where the outer peripheral edges of the front surface material and the rear surface material are heat-sealed to each other, unlike the case of sewing, they can be easily manufactured.

In the case where a through hole is formed at an appropriate position on the side edge of the outer peripheral end of the front surface material and the back surface material, a large amount of air can be supplied into the housing in addition to the opening. In order to discharge the air, the opening is particularly pressed against the laying surface and adheres to some extent, but does not adhere completely due to the step. Therefore, a gap is generated, so that the air can be discharged, and the air can be easily discharged from the through-hole, so that fresher air can be circulated. When the user stands up or moves the center of gravity right and left, air is taken in again from the opening and air is also taken in from the through-hole and absorbed by the soft foam material in the accommodating portion.

As a surface material, a soft foam material is interposed between the front sheet material and the inner sheet material, and the entire outer peripheral edges of the surface sheet material and the inner sheet material are heat-sealed. When a soft foam material is interposed between the back sheet material and the inner sheet material and the entire outer peripheral edge of the back sheet material and the inner sheet material is heat-sealed, the soft foam material is coated with an adhesive or the like. It can be interposed without use. Further, it can be easily manufactured and mass production is possible.

In the case where a material having a large number of ventilation holes is used as the inner sheet material, the air taken in from the through holes is once supplied to the inside of the accommodation portion, that is, to the soft foam material. Then, by the movement of the center of gravity of the user, the stored air is exhausted from the ventilation holes, and the air spreads to every corner in the housing portion.

Further, when a soft vinyl chloride resin is used as the front sheet material, the back sheet material, and the inner sheet material, heat fusion becomes easy and the cost can be reduced.

Then, as a soft foam material, the thickness is 10 m.
m or more, the elastic force is further improved, and the step of the opening is increased, and a gap is generated between the floor surface and the opening due to the subtle movement of the center of gravity of the user. Air can be taken into the unit.

Further, when the handle is attached to an appropriate place of the fastening portion where the outer peripheral ends of the front and rear members are fastened to each other, the portability is improved and the use range is expanded.

In addition, such a cushion can be carried and used as a carrying bag by attaching a handle, or as a shoulder bag by attaching a string or the like to the through hole. ,
You can use it as a hat if you push out the housing.

Next, in the case where a heating element which generates heat by taking in oxygen into the housing portion is provided, an opening having a step is provided to form a gap between the opening and the laying surface. Air can be taken in by a slight shift of the center of gravity of the user, and air is also taken in from the through hole. Therefore, a large amount of air can be supplied from the opening and the through hole. Then, the air taken in from the through hole is absorbed by the soft foam material in the housing portion, and spreads to every corner in the housing portion through the vent hole provided in the inner sheet material. Therefore, although the heating element is pressed by the weight of the user, it is possible to take in sufficient air from the opening and the ventilation hole with a slight movement of the center of gravity and supply the air that the built-in heating element can generate sufficiently. And promote and maintain warm conditions.

Further, as described above, when a through hole is formed at an appropriate position on the side edge of the outer peripheral end of the front surface material and the back surface material, a large amount of air is supplied into the housing in addition to the air taken in from the opening. can do. In order to discharge the air, the opening is particularly pressed against the laying surface. Therefore, there is a gap,
The air can be discharged, and at the same time, the air is easily discharged from the through-hole, so that fresher air can be distributed to every corner in the housing portion. And
When the user stands up or moves the center of gravity right and left, air is taken in again from the opening and the through hole, and absorbed by the soft foam material in the accommodating portion. Therefore, sufficient air that allows the heating element to generate heat only by moving the center of gravity of the user can be taken into the housing portion, and the warm state can be maintained for a long time.

As a surface material, a soft foam material is interposed between the front sheet material and the inner sheet material, and the entire outer peripheral edges of the front sheet material and the inner sheet material are heat-sealed, When a soft foam material is interposed between the back sheet material and the inner sheet material and the entire outer peripheral edge of the back sheet material and the inner sheet material is heat-sealed, the soft foam material is coated with an adhesive or the like. It can be interposed without use, can be easily manufactured, and can be mass-produced.

In the case where a material having a large number of ventilation holes is used as the inner sheet material, the air taken in from the openings and the through holes is once supplied to the inside of the accommodation part, that is, to the soft foam material, Next, air is discharged from the air holes provided in the inner sheet material. Therefore, it is possible to accumulate and supply oxygen required for the heating element to sufficiently generate heat in the soft foam material without directly sending oxygen to the storage section.

Further, when a soft vinyl chloride resin is used as the front sheet material, the back sheet material, and the inner sheet material, heat fusion becomes easy and the cost is lower than when other thermoplastic resins are used. Therefore, cost can be reduced.

Then, as a soft foam material, the thickness is 10 m.
m or more, the elasticity is further improved, and the step of the opening is increased, and a gap is formed between the opening and the floor surface even by a delicate movement of the center of gravity of the user, so that the space can be accommodated. Air can be taken into the compartment, and the air always reaches all corners in the compartment.

When the handle is attached to an appropriate place of the fastening portion where the outer peripheral ends of the front surface material and the back surface material are fastened to each other, the same effect as described above is obtained.

In addition, such a cushion with a heating element is firstly housed by inserting a heating element from an opening.
Then, when the user is seated, the air in the storage section is discharged from the opening and also discharged from the through hole. Then, by the subtle left and right center of gravity movement of the user, the air is quickly supplied again from the through hole, and the air is also supplied from the opening gradually opening the gap. Therefore, even if the user remains in a seated state, air can be taken in by a slight movement of the center of gravity, and oxygen capable of sufficiently generating heat can be taken in by the heating element, and a warm state can be maintained for a long time.

FIG. 9 is an enlarged end view taken along line bb in FIG. 7, and FIG. 9 is a sectional view showing a state in which a heating element is provided. The cushion B with a heating element shown in FIG. 7 can be installed by inserting a heating element 16 that generates heat by supplying oxygen to the opening 15.
This is particularly suitable for outdoor use such as watching sports or leisure in winter. Then, in order to store the heating element 16, first, a hand is inserted into the opening 15. When the back end piece 2b is pulled toward the front with the adjacent end portion 13b of the back end piece 2b, the back end piece 2a naturally opens upward as shown in FIG. 8, and the heating element 16 can be installed as shown in FIG. It is. In this way, the interior of the heating element 16 can be warm and very convenient when used outdoors, especially in winter, and when the heating element 16 loses its effectiveness, it can be replaced as appropriate and used repeatedly. When the heating element 16 is housed in the housing 18 and the user sits down, the heating element 16 is completely pressed by the weight of the user and is sealed in the housing 18, so that oxygen is supplied. Is shut off, and the heating element 16 does not generate heat. However, according to the present invention, sufficient air can be taken into the housing portion 18 only by a slight movement of the center of gravity of the user left and right, and the heating element 16 can generate heat without shutting off the supply of oxygen. You can do it. That is, the cushion B with a heating element of the present invention is provided with the through-hole 8b in the heat-sealed portion 6 or at a proper position on the side edge 7b of the surface material 1 and the back piece 2a with the heat-sealed portion 6 interposed therebetween.

By forming the pores 9, the circulation of oxygen can be further improved, and the heating element 16 can be maintained at a constant temperature for a long time. More specifically, first, when the user sits down, the opening 15 comes into close contact with the facing laying surface. Therefore, the air is discharged from the opening 15 and the air is also discharged from the through holes 8a and 8b. Then, when the user slightly moves the center of gravity, the through hole 8a
Air is supplied from 8b and is taken in the accommodation portion 18, and is also taken in from the opening 15 forming a gap. Since a large number of ventilation holes 9 are formed in the inner sheet members 5, 12a and 12b, air is distributed to all corners in the housing portion 18. Also, the inner sheet materials 5, 12
Since the plurality of ventilation holes 9 are provided in the holes a and 12b, the contact area between the inner sheet members 5, 12a and 12b is extremely small, and there is no close contact even when the seat is seated for a long time. Therefore, the opening 15 does not adhere to each other and creates a gap,
The heating element 16 can supply oxygen that can sufficiently generate heat even when the center of gravity of the user is slightly moved.

It should be noted that the heating element 16 is not directly laid, and the heating element 16 is made of a thermoplastic resin such as a vinyl chloride resin or a polyethylene resin, a synthetic resin other than the thermoplastic resin, or a rubber or other water-impermeable material. Heating element 16 for coating
Does not come out even if the water contained in it evaporates. Thus, the user's buttocks do not get wet and give any discomfort.

Further, if a storage pocket capable of fixing the position of the heating element 16 is provided at an appropriate position of the inner sheet members 5, 12a, 12b, no positional displacement occurs. FIG. 10 shows that the cord 17 can be used as a shoulder bag by passing the string 17 or the like through the through holes 8a and 8b. If it is rained outdoors, the opening 15 can be pushed as far as possible and used as a hat. it can. In addition, it is possible to protect the entire body from rain by providing rain gear in the housing portion 18 and using the cushion as a hat. It is also possible to appropriately provide two or more handles 14. Further, in order to improve the convenience, a partition or the like may be provided at the center so that the folding can be performed.

FIGS. 11 and 12 show examples of designs of the cushion A and the cushion B with a heating element according to the present invention. If a soccer ball image is printed, the commercial value increases. is there. Further, it is easy to adopt the design of baseball balls, tennis balls, and the like. In addition, if the coloring is made a fluorescent color or the like, it can be used as a support goods or the like.
