Description

  The present invention relates to a heat insulating sheet and a heat insulating futon using the same.

  A heat insulating sheet for maintaining the surface of a living body that is a human being or other animal, comprising a sheet-like base material, and forming a heat insulating surface by impregnating a heat insulating material on the surface of the base material on the living body side. A heat-insulating sheet in which the heat insulating surface is covered with a coating layer is known (for example, see Patent Document 1).

JP 2001-327437 A (FIG. 4)

The heat insulating sheet of the above document is affected by the material of the base material because the surface on the living body side of the base material is impregnated with a heat insulating material to form a heat insulating surface and the heat insulating surface is covered with a coating layer. In addition, heat insulation can be performed, and the heat insulation surface protected by the coating layer can easily maintain the heat insulation performance.
However, since the coating layer is composed of a plastic film or the like, the body temperature on the living body side hardly reaches the heat insulation surface and is diffused along the surface of the coating layer, so that the heat from the living body side can be used efficiently. Is difficult.

  The present invention provides a heat insulating sheet in which a heat insulating surface is formed by impregnating a heat insulating material on a living body side surface of a base material, and the heat insulating sheet is covered and protected so that the body temperature on the living body side can be easily used. It is another object of the present invention to provide a thermal futon using the same.

  The heat insulating sheet of the present invention is a heat insulating sheet for maintaining the surface of a living body that is a human being or other animal, and includes a sheet-like base material that can be flexibly changed, and a non-woven fabric or a woven fabric that ensures air permeability. A heat insulating surface is formed by impregnating or applying a heat insulating material on a living body side surface of the base material, and the heat insulating surface of the base material is covered with the cover body.

  The base material may be composed of woven fabric, non-woven fabric, felt or Japanese paper, and the cover body may be composed of woven fabric or non-woven fabric.

  The heat insulating material has a hollow bead structure and includes a sodium aluminosilicate glass having a particle size of 10 to 50 μm, a pigment, a resin emulsion, a dispersant, and an adhesive, and contains the sodium aluminosilicate glass. The amount may be 10-20% by weight of the total weight of the insulation.

  The cover body may be sewn or bonded to the base material in a state of being in close contact with the heat insulating surface of the base material.

  The whole base material may be impregnated with a heat insulating material to make both surfaces of the base material heat insulating surfaces, and the cover body may cover both side surfaces of the base material.

  By applying or impregnating a heat insulating material only on one side of the base material, one side of the base material may be used as a heat insulating surface, and the other side may be used as a non-heat insulating surface.

  Moreover, the heat insulation futon of the present invention is characterized in that the heat insulation sheet is accommodated in an accommodation portion formed in the duvet cover.

  A plurality of the accommodating portions may be formed on the futon cover so as to be aligned in the height direction of the sleeping person, and a heat insulating sheet may be accommodated in each accommodating portion.

  Since the heat insulating surface of the base material is covered by a cover body made of a non-woven fabric or woven fabric with air permeability ensured, the body temperature on the living body side passes through the cover body and reaches the heat insulating surface or remains on the living body side. It becomes easy to be heat-reflected, and the heat on the living body side can be used efficiently during heat insulation.

It is a top view of the mattress to which the present invention is applied. It is AA sectional drawing of FIG. It is BB sectional drawing of FIG. (A) is explanatory drawing of the single side | surface side of the heat retention sheet | seat to which this invention is applied, (B) is explanatory drawing of the other side. It is CC sectional drawing of FIG. 4 (A). It is sectional drawing which shows the other structural example of a heat retention sheet.

  1 is a plan view of a mattress to which the present invention is applied, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. A mattress (heat insulation futon) 1 shown in these drawings includes a mattress cover (futon cover) 2 and a rectangular plate-shaped heat insulation sheet 4 accommodated in a housing part 3 formed on the mattress cover 2 so as to be removable. Yes.

  The mattress cover 2 is a cloth bag body with sufficient air permeability and water permeability. Specifically, the mattress cover 2 is a bag that extends in the height direction of a sleeping person (living body) by partially joining one or more flexible cloths by stitching or bonding. It is formed into a shape. In other words, in the mattress 1 and the mattress cover 2, the full length direction (Y direction shown in FIG. 1) is set to the height direction of the sleeping person, and the direction orthogonal to the height direction is the width direction (X direction shown in FIG. 1).

  The bag-shaped interior of the mattress cover 2 is divided into a plurality of partitions (2a) in the width direction (X direction) formed by stitching or adhering opposing fabrics, whereby a plurality of bag-shaped portions 2b are formed. And a storage portion 3 is formed in each bag-like portion 2b.

  A plurality of storage portions 3 (bag-like portions 2b) are arranged in parallel in the Y direction. An insertion portion 3 a for inserting and inserting the heat insulating sheet 4 into the housing portion 3 so as to be removable is formed at one end portion or both end portions in the X direction of each housing portion 3.

  The insertion portion 3a is closed by engaging the opposing portions detachably with an engagement tool (not shown) such as a velvet fastener or a button. In the state where the insertion portion 3a is closed, accommodation of the heat insulating sheet 4 in the accommodation portion 3 and removal from the inside of the accommodation portion 3 are restricted (prohibited), while in the opened state, the insertion portion 3a is interposed via the insertion portion 3a. Thus, the heat insulating sheet 4 can be taken in and out of the housing portion 3.

  A heat insulating sheet 4 located at the foot end of the mattress cover 2 and a bag-like portion 2b (foot-side upper hanging portion 6) having an accommodating portion 3 for accommodating the same are accommodated, and the adjacent heat insulating sheet 4 and the same are accommodated. By folding the bag-like part 2b (foot-side underlay part 7) having the accommodating part 3 inside, the bedside part 6 is placed between the foot-side upper hanging part 6 and the foot-side underlay part 7. A space for inserting feet is formed. In other words, in the unfolded state, the surface facing upward in the foot-side upper hanging portion 6 is directed downward when folded as described above.

  In addition, the other end of the mattress cover 2 (specifically, the end portion (tip portion) far from the connecting portion with the footside underlay portion 7 in the footside upper hanging portion 6 is connected by a band-shaped connecting body 8. In this way, the foot-side upper hanging part 6 is held in a folded state. Incidentally, the coupling bodies 8 are respectively provided on both end sides in the width direction of the mattress cover 2.

  The heat insulating sheet 4 located at the head side end of the mattress cover 2 and the bag-like portion 2b (head side underlay 9) having the accommodating portion 3 for accommodating the same are the heat insulating sheet 4 located next to the bag-like portion 2b. It folds up on the upper surface side of the bag-like part 2b (folded part 11) which has the accommodating part 3 which accommodates this inside. In other words, in the unfolded state, the surface facing upward of the head-side underlay 9 is directed downward when folded.

  Moreover, since the length of the head side underlay 9 in the Y direction is shorter than the length of the folded portion 11 in the Y direction, when overlapped in this way, the folded portion 11 and the head side The underlay 9 is not partially wrapped, but is partially wrapped.

  Next, the configuration of the heat insulating sheet 4 will be described in detail with reference to FIGS.

  4A is an explanatory view on one side of a heat insulating sheet to which the present invention is applied, FIG. 4B is an explanatory view on the other side, and FIG. 5 is a cross-sectional view taken along the line CC in FIG. FIG. The heat insulating sheet 4 has a rectangular sheet-like base material 12 that can be deformed flexibly, and a cover (cover body) 13 that covers at least one side of the base material 12 in a close contact state.

  The material constituting the base material 12 includes a woven fabric made by weaving a fiber twisted into a yarn, a non-woven fabric that is intertwined into a sheet without weaving the fibers, animal hair and chemical fibers thinly. A sheet-like felt made by compressing into a plate shape, a Japanese paper made into a thin sheet while entwining long fibers such as plants, etc. are used. The base material 12 made of these materials can be bent and stretched, is not easily damaged, and has sufficient breathability and water permeability. Therefore, sweating from the skin can be evaporated in a short time, and washing Also easy to do.

  The heat insulating layer 14 is formed by applying or impregnating the heat insulating material on one side of the base material 12, and the surface on the side of the base material 12 on which the heat insulating layer 14 is formed thereby forms the heat insulating surface 14a. Become.

  The heat insulating material is a white solution obtained by blending aluminosilicate glass, a pigment, a resin emulsion, a dispersant, an adhesive, and the like, adding water, and stirring and mixing.

  The aluminosilicate glass has a hollow bead structure with a particle size of 10 to 50 μm, and the content of the aluminosilicate glass is 10 to 20% by weight of the total weight of the heat insulating material. Incidentally, when the content of sodium aluminosilicate glass is less than 10% by weight, the heat insulation performance is lowered, and when it exceeds 20% by weight, the adhesive force to the substrate is lowered. It is set.

  The pigment is white titanium dioxide that reflects light, the resin emulsion is a water-soluble acrylic emulsion resin, and the dispersant is a uniform mixture of component materials consisting of aluminosilicate soda glass, pigment, and resin emulsion. The pressure-sensitive adhesive is for suppressing separation and precipitation of the above-mentioned component materials that are uniformly mixed.

  When the liquid heat insulating material in which these are mixed is uniformly applied to one side of the base material 12 by spraying from a nozzle or the like and then dried, the heat insulating material is impregnated from the surface of the base material 12 to a predetermined depth so that the above heat insulating material is obtained. Layer 14 is formed. By the way, when applying the heat insulating material to the base material 12, the surface on the side to be applied is applied upward, and the state is maintained even during drying.

  That is, the heat insulating material is a heat insulating paint, and is applied to and impregnated on the surface of the base material 12 to form a heat insulating layer 14 that is resistant to bending and has high durability on the surface layer of the base material 12. For this reason, the base material 12 is also comprised from the above materials so that a heat insulation coating material can be impregnated.

  In addition, you may make this base material 12 impregnate a heat insulating material by immersing the base material 12 in a liquid heat insulating material. In addition, the heat insulating paint may be simply applied to the surface of the substrate 12. In this case, since it is not necessary to impregnate the heat insulating material of the base material 12, the base material 12 does not need to ensure permeability to the liquid, so that the degree of freedom in selecting the material is improved.

  The cover 13 is composed of a woven fabric or a non-woven fabric that ensures air permeability and water permeability. The cover 13 covers a range from the heat insulating surface 14a of the base material 12 to the four sides of the non-heat insulating surface 12a that is the side opposite to the heat insulating surface 14a of the base material 12.

  Further, the specific configuration of the cover 13 will be described. At least a part of the surface of the cover 13 (the whole in this example) is exposed to the material constituting the cover 13 as it is, and pigments and the like that impede air permeability and water permeability. The layer is not formed.

  Then, when the heat insulating sheet 4 with the heat insulating surface 14a directed toward the sleeping person is brought close to the sleeping person's body, the body temperature of the sleeping person reaches the heat insulating surface 14a through the mattress cover 2 and the cover 13, The space between the heat insulating surface 14a and the sleeping person is kept at a comfortable temperature because it stays on the spot or is reflected on the living body side.

  The fixing means of the cover 13 to the base material 12 will be further described. The cover 13 is bonded or stitched to the base material 12 in a state where the cover 13 is brought into contact (more specifically, in close contact) with the entire heat insulating surface 14a. ing.

  Specifically, the cover 13 is impregnated with a hot melt such as a urethane adhesive, and this is applied to a bonded portion of the base material 12 with a high-temperature iron (or more specifically, about 120 to 160 ° C.) or a metal plate ( The cover 13 is adhered to the base material 12 by applying pressure (hot pressing) to the whole heat insulating surface 14a and the non-heat insulating surface 12a while being heated. The cover 13 is sewn in a staggered pattern. Further, the cover 13 may be attached to the substrate 12 by a combination of adhesion and stitching.

  The protective sheet 4 having such a configuration is basically accommodated in the accommodating portion 3 of the mattress cover 2 in a posture in which the heat insulating surface 14a is directed toward the sleeping person (specifically, a posture in which the heat insulating surface 14a is an upper surface). Is done.

  By the way, the foot-side upper hanging portion 6 in the folded state has a lower surface on the bedside side, so that the heat insulating surface 14a of the heat insulating sheet 4 of the foot-side upper hanging portion 6 faces downward in the folded state. In the posture, the heat retaining sheet 4 is accommodated in the accommodating portion 3 of the foot side upper hanging portion 6.

  On the other hand, the head-side underlay 9 is used while being folded and positioned on the upper surface side of the sleeping person's head. However, since the head is less likely to be kept warm, The heat insulating sheet 4 is accommodated in the accommodating portion 3 of the head side underlay 9 such that the heat insulating surface 14a of the heat insulating sheet 4 of the head side underlay 9 faces downward.

  According to the mattress 1 of this configuration, since the heat insulating sheet 4 with the heat insulating surface 14a facing the sleeping person is in a state of being close to the sleeping person, the temperature of the sleeping person is caused by the flow of air, and the comforter cover 2 and Since it passes through the cover 13 and reaches the heat insulating surface 14a and stays on the spot or reflects to the sleeping person side, the space between the heat insulating sheet 4 and the sleeping person is heated or kept at an appropriate temperature. The

  Further, since the heat insulating sheet 4 located in the portion where the sleeping person does not need to be kept warm is directed to the sleeping person side by facing the non-insulating surface 12a, the sleeping sheet is not uncomfortablely kept. One can sleep more comfortably. Incidentally, when there is no need to keep warm, such as at the waist and legs, other than the head, the non-insulating surface 12a of the heat-insulating sheet 4 at that portion may be directed toward the sleeping person side.

  In addition, the heat insulating sheet 4 is formed by applying and impregnating a base material 12 that can be changed flexibly with a heat insulating paint, thereby forming a heat insulating layer 14 and covering the heat insulating layer 14 with a cover 13 for protection. Therefore, even if twisting, bending, or washing is performed, there is little risk of breakage and peeling, and high durability can be expected.

  Furthermore, since the numerous aluminosilicate glasses are laminated innumerably and are linked in a plane along the heat insulation surface 14a, the heat reaching the heat insulation layer 14 is reflected on the surface of the sodium aluminosilicate glass. Thus, transmission is suppressed, and planar convection heat and conduction heat along the heat insulating surface 14 are also suppressed by the hollow portion of the aluminosilicate glass.

  By the way, when considering the cause of the aluminosilicate soda glass being linked in a plane along the heat insulating surface 14a, the aluminosilicate soda glass has a hollow bead structure and the heat insulating paint (heat insulating material) is a liquid having fluidity. Therefore, buoyancy acts on the aluminosilicate soda glass in the heat insulating coating applied to the substrate 12 until it is dried. Due to this buoyancy, the aluminosilicate glass is accumulated on the surface layer on the upper surface side of the heat insulating paint (that is, on the heat insulating surface 14a side).

  This is considered to be one of the reasons why the aluminosilicate soda glass is planarly linked along the heat insulating surface 14a. In addition, since the heat insulating paint is impregnated into the base material 12 in the drying process as described above, the heat insulating paint adheres to each fiber of the base material 12.

  In such a state, the heat from the living body reaches the aluminosilicate soda glass through the cover 13 in a radiant heat state, and raises the aluminosilicate soda glass to the same level as the body temperature of the living body. As the temperature rises, the aluminosilicate soda glass emits a minute amount of far-infrared rays toward the living body, which becomes a phenomenon of heat reflection and comfortably warms the living body.

  However, when the heat-insulating sheet 4 (particularly the heat insulating surface 14a side) is soiled by sweat from a living body or foreign matter adhered to clothing, the surface of the sodium aluminosilicate glass is soiled and a film is formed. This coating absorbs the far-infrared rays and reduces the efficiency of the heat reflection of the heat insulating sheet 4.

  In order to prevent this, it is necessary to wash the heat-insulating sheet 4 and remove the dirt film formed on the surface of the aluminosilicate glass. Since the heat insulating surface 14a is covered by the cover 13 and the base material 12 is composed of fibers having excellent water permeability, when the heat insulating sheet 4 is washed, the heat insulating paint is peeled off from the base material 12, 12 is prevented from being damaged, and dirt can be removed from each of the fibers of the substrate 12.

  As described above, the heat insulating sheet 4 can be repeatedly washed, and in each washing, the dirt film formed on the surface of the aluminosilicate sodium glass is surely removed, and thereby the heat reflection efficiency of the heat insulating sheet 4 is improved. Can be restored (replayed).

  In addition, the heat insulating sheet 4 may be applied to a comforter, may be used for other bedding such as pillows, and is further used for a knee-hanger, a hat, an insole, a pad or other wearing equipment, and a seating sheet. In addition, it may be used not only for people but also for other animals such as dogs and cats. At this time, the heat-insulating sheet 4 arranged at the place where the living body is kept warm is used with the heat insulating surface 14a facing the living body and approaching the living body.

  Next, a different point from the above-mentioned form is demonstrated about other embodiment of a heat retention sheet | seat based on FIG.

  FIG. 6 is a cross-sectional view showing another configuration example of the heat insulating sheet. The heat insulating sheet 4 shown in the figure is made by impregnating the whole base material 12 with a heat insulating paint, thereby making the whole base material 12 a heat insulating layer 14, both surfaces thereof being heat insulating surfaces 14 a, and each heat insulating surface 14 a, Covered by a cover 13. At this time, in order to easily impregnate the entire base material 12 with the heat insulating paint, the thickness of the base material 12 may be set thinner than that described above.
