Description

  The present invention relates to a bedding, and more particularly, a bedding formed by filling a heat-insulating material such as feathers and an elastic material into the inside, and can be comforted during sleep and used for a long time. About.

  As the bedclothes for sleeping, a mattress or a mattress is generally used. The mattress is configured such that a filling material such as cotton is sealed in the futon side so as not to move in the futon side in the bag-like side. In the bedding such as mattresses and mattresses, if the sleeper's body and the mattress are unfamiliar with the mattress, the mattress gives a feeling of pressure to the sleeper's body, and the sleeper's back, waist, thighs, etc. The pressure from the mattress adds to the disturbing sleep.

  In recent years, low-resilience urethane foam has been widely used as a pillow or mattress material as a material having excellent pressure resistance and flexibility to reduce impact. However, since a single low-resilience urethane foam has no breathability and hygroscopicity, moisture released from the body stays on the surface of the material, causing a so-called drowsy symptom. Therefore, a mattress in which a soft urethane foam having an acupressure pad on the upper surface is combined with an upper portion of a low-resilience urethane foam has been proposed. (See Patent Document 1). However, this mattress only obtains air permeability by the space between the acupressure pads, and the air permeability of the compressed acupressure pad portion is not ensured.

On the other hand, feathers that have excellent heat retention and hygroscopicity and are lightweight are widely used for fillings of futons as bedding. However, since feathers are weak under heavy pressure, they are crushed by slight compression, and the heat retaining power, which is a characteristic, is lost. Therefore, as a duvet that combines the advantages of cotton and feathers, a cotton filling layer that contains cotton and quilted between the lining and the middle and a double-sided adhesive tape on the middle are used. A duvet has been proposed which has a feather layer filled with feathers by providing a mesh-like feather accommodating chamber between the outer surface and the outer surface. (See Patent Document 2). However, in this duvet, the feather layer is only covered with the front side land, and no consideration is given to the pressure on the feather, and it is used as a comforter and cannot be used as a bedding. It seems to be.
Mattresses for mattresses generally have the disadvantage that they are poorly breathable and dwell in moisture, making it impossible to prevent stuffiness. In addition, even if feathers are used for the mattress, conventionally, maintaining the bulkiness of the feathers against compression cannot be achieved, and if they are used for a certain period of time, the inner feathers will be crushed and the heat retention performance and bulkiness will deteriorate. As a result, the original feeling of use cannot be obtained.

  The present invention has been made in view of the above-described problems related to bedding, and is a bedding having good cushioning properties, heat retaining properties, air permeability, excellent sleeping comfort, and for long-term use. The purpose is to provide a bedding that can withstand.

The bedding of the present invention comprises a bag-like side land composed of front and back sides, and a plurality of columnar small compartments aligned in the thickness direction of the bedding by a partition cloth material provided between the front and back sides. In each small compartment, an inner bag containing a cylindrical elastic body portion having a void portion penetrating in the thickness direction of the small compartment chamber and a heat insulating material filled in the void portion of the cylindrical elastic body portion. In addition to filling the body, an insertion port for each small compartment was provided on one side of the front and back sides of the small compartment. The heat insulating material filled in the gap portion is feathers, and a part or all of the elastic body constituting the cylindrical elastic body portion in the small compartment is formed of low-resilience urethane foam.
The cylindrical elastic body part made of low-resilience urethane foam is formed by laminating low-resilience urethane foams with different elasticity, and the elastic properties of the elastic body of the small compartments are made different according to the position in the bedding body. A small compartment can also be arranged.

  In the down comforter of the present invention, the heat insulating material feathers and elastic materials are formed as a set of small compartments using a combination of members having complementary material characteristics in an alternate or circumferential manner. Therefore, it is characterized in that feather damage is prevented and both durability and air permeability are achieved. In addition, a partition is provided between each small compartment, and the partition material is sewn or fused and fixed to the upper and lower fabrics, so that the shape is firmly maintained against impact during use, and the function of correcting deformation and distortion instantaneously is provided. By having it, the feeling of comfort is dramatically improved, the sleeping comfort is improved, and the durability is remarkably improved. Each component of the bedding is formed as an independent set, so that the weighted impact during use does not spread to the surroundings, dramatically improving sleep stability and comfort compared to conventional monolithic products. It became possible.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 thru | or FIG. 4 shows the 1st embodiment of the duvet which is a bedding of this invention. 1A is a plan view of a duvet, FIG. 1B is a front view, FIG. 2 is a partially cut bottom view of the duvet shown in FIG. 1A, and FIG. 3A is an enlarged view showing the back surface of the front side fabric, FIG. FIG. 4 is a partially cut plan view showing an example of a filling body filled in a down comforter.

  The duvet 100 shown in FIGS. 1 and 2 divides the interior of a mattress body having a bag shape made of front and back side grounds 1 and 3 into hexagonal columnar small compartments 5 having a height in the thickness direction of the futon, By providing an insertion port portion 5a in each of the portions corresponding to the rear surface side end surface of each small compartment 5 on the futon back side fabric 3, and inserting and storing the filler 6 into each small compartment 5 individually from the insertion port portion 5a. It is configured. The duvet 100 has a width of 100 cm, a length of 195 cm, and a thickness of about 3 cm, for example.

  The duvet 100 is arranged between the front side fabric 1 and the back side fabric 3 with a partition fabric material 2 (saddle) having a width substantially equal to the thickness of the duvet bent at a predetermined length of 120 degrees, and arranged on the front side fabric 1 and the back side fabric. By bonding or sewing to the ground 3, hexagonal small compartments (5, 5, 5,...) Are continuously formed on the entire surface of the mattress inside the front side ground 1 and the back side ground 3. . Each sub-compartment chamber 5 formed inside the front side ground 1 and the back side ground 3 is individually filled with a packing body 6 in which an elastic body 7 described later and feathers 9 as a heat insulating material are wrapped in an inner bag body 10. The Reference numeral 4 denotes an edge cloth composed of the front side ground 1 and the back side ground 3.

  For the manufacture of such a down comforter 100, general stitching is also possible, but in this embodiment, bonding is used instead of stitching. In this case, the front cloth 1 and the back cloth 3 corresponding to the front cloth 1 as described above, and the partition cloth material 2 in which an adhesive is applied to the width direction end bonded to both are prepared. Then, on the back side surface of the front side material 1 that is spread over on the work plane, the design LP is displayed at a position clearly shown from the back side of the front material 1 as shown in FIG. 3A, and the partition cloth material 2 is arranged accordingly. . Next, the partition fabric material 2 is fixed so that the small compartment 5 is formed inside the futon by heating and pressure-curing the adhesive while the backside fabric 3 is aligned with the front fabric 1 and held together. As shown in FIG. 3B, the partition fabric material 2 also forms a small compartment 5 having an insertion port 5 a for the filler 6 as shown in FIG. 3B.

  Next, the manufacturing process of the side land (bag body) of the down comforter 100 will be described in more detail. Prior to the direct operation, a front side ground 1 is prepared by printing on the back side a design clearly showing all the division line positions of the small compartment 5 to be formed (see FIG. 3A). On the side of this figure, a linear pattern LP substantially matched with the lane marking position is used. A design adapted to the small compartment 5 to be formed is printed on the back of the front fabric 1 in the duvet 100. That is, a hexagonal pattern LP that is substantially coincident with all the dividing lines dividing a large number of hexagonal small compartments 5 continuous in both directions as a pattern is printed on the surface side. The pattern LP is determined so that it can be easily visually recognized by the difference in color and brightness.

  The symbol may be a symbol that can clearly indicate all lane marking positions even if it is not completely linear, and may be a dot pattern or the like that is discretely arranged at a density of a certain level or more along the lane marking. In this case, it is easy to understand that a dotted pattern is present at a position corresponding to the bending point (vertical corner) of the lane marking. Needless to say, an appropriate pattern may be printed between the linear symbols. The pattern LP does not need to be completely continuous corresponding to the whole lane marking, and patterns are printed at several points along each apex and each side so that the hexagonal shape can be easily extracted. In short, it suffices that the position of the compartment can be specified by simple visual inspection. As will be described later, during the actual bag manufacturing process, the position of the compartment is visually recognized from the back side of the front surface 1. Of course, other symbols may be printed in addition to the above-mentioned symbols. For example, a hexagonal figure with a flower pattern at the center is aesthetic and has high design.

  Then, a back side 3 having substantially the same area as the front side 1 is prepared (see FIGS. 3A and 3B). The back side fabric 3 is a piece of cloth having a substantially equal area to the front side fabric 1 with a plain or arbitrary pattern. At positions corresponding to the respective small compartments (5, 5,...), Cuts serving as the insertion openings 5a of the filler 6 are formed. As for the partition cloth material 2 interposed between the front side ground 1 and the back side ground 3, the adhesive agent is apply | coated to the width direction edge part, ie, the upper-lower-end part of the futon thickness direction. Other parts of the side grounds 1 and 3 are not particularly different from those conventionally known as duvets. Next, the partition wall between the front side land 1 and the back side ground 3 according to the design LP clearly showing the small compartment 5 of the front side ground 1 by overlapping the position of the front side ground 1 and the paired back side ground 3 in a position. A large number of small compartments 5 each having an insertion opening 5a are formed by interposing and fixing the cloth material (saddle part) 2.

  In addition, since the futon material is generally thin, it is usually easy to see through the back side, but it may be difficult to see through the back side depending on the color and brightness of the design. If you illuminate from the bottom of the material, you can easily see the design.

  Subsequently, the front side ground 1 and the back side ground 3 that are paired with each other are overlapped and held together so that the adhesive is cured by passing a heat roller, etc. 2 is adhered and fixed. In this way, a large number of hexagonal small compartments 5 each having an insertion opening 5a are formed. The peripheral portions of the front and back side grounds 1 and 3 are sealed with the edge cloth 4 to form the outermost peripheral part of the duvet 100 to obtain a side surface of the bag-like body as a whole. Manufacturing using the bonding means can be applied to a complicated shape such as a continuous hexagonal shape of the small compartment. A bag-like body can be made only by sewing without using adhesion, but the number of processes is inferior.

  Next, the structure of the filler 6 inserted into the hexagonal small compartment 5 formed as described above will be described. FIG. 4 is a partially cut plan view showing an example of the structure of the filler 6. Each of the fillers 6 was filled into a hexagonal cylindrical elastic body portion 7 that was long in the direction of the thickness of the futon, a space portion 8 that was a circular through hole provided at the center of the elastic body portion, and a space portion 8. It is comprised by the feather 9 as a heat insulating material, and the inner bag body 10 which encloses the elastic-body part 7. FIG. More specifically, the filling body 6 has an inner peripheral body 10 made of a cloth with good air permeability, and the outer peripheral shape of the cross section as the elastic body portion 7 substantially matches the cross sectional shape of the corresponding small compartment 5, A low-resilience urethane foam as the elastic body portion 7 formed in a substantially cylindrical shape having a circular through hole as the space portion 8, and feathers 9 filled as a heat insulating material in the space portion 8 at the center of the elastic body portion 7. It becomes more.

  The low-rebound urethane foam that is the material of the elastic body portion 7 is based on a so-called soft urethane foam material having a large molecular weight, and the material has a low rebound resilience (rebound resilience is about 20%, for example). Less than) those having difficulty in returning can be used.

  FIG. 5 shows another form of filler 106. In this example, as shown in the figure, a cylindrical elastic body 107a is further arranged at the center of an annular hexagonal columnar elastic body 107, and a feather is formed in an annular gap 108 formed between them. 109 is filled and enclosed in an inner bag 110 to form a filler 106.

  6 shows still another form of the filling body 206, FIG. 6A is a partially cutaway plan view of the filling body, and FIG. 6B is a sectional view taken along the line VI-VI of FIG. 6A. A substantially hollow portion 208 having a circular through-hole is formed at the center so that the planar shape in the futon 100 is in contact with the hexagonal inner bag body 210 when the planar shape combined with the cross-sectional shape of the hexagonal small compartment 5 is inscribed. As a heat insulating material, an elastic body portion 207 formed in a cylindrical shape, a central cavity portion 208 of the elastic body portion 207, and a void portion 208a formed on the inner surface of the corner portion of the inner bag body 210 on the outer peripheral side of the elastic body portion 207 Filled feathers 209 are enclosed in the inner bag body 210. The elastic body portion 207 may be formed of the same elastic body in the whole thickness direction, but may be partially different elastic bodies. That is, the elastic body portion 207 does not have to be a uniform low-resilience urethane foam, for example, and may be laminated with low-resilience urethane foams having different elasticity as shown in FIG. 6B. FIG. 6B shows a structure in which a low-resilience urethane foam 207a having a constant thickness and a low-resilience urethane foam 207b harder than this are laminated. Moreover, not all the elastic body parts 207 need to be low-resilience urethane foam, and may be laminated with other elastic members.

  As a final step, the filling bodies 6, 106, 206 as described above are filled in all the small compartments 5 of the above-mentioned mattress body from the respective insertion openings 5a, and then the insertion openings 5a are sealed (sewn or locked). The desired duvet is completed.

  In the down comforter 100 shown in FIG. 2, such an elastic laminate having a sufficiently low resilience can support the body suitably at the time of sleeping and provide a good sleeping comfort and reduce the collapse of the internal feathers 9. Can do. The elastic body 7 of low-resilience urethane foam is poor in hygroscopicity but can be used comfortably without the sleeper being concerned about moisture due to the presence of a layer of annular feathers 9 penetrating vertically. As described above, in the present invention, the combination of the feather 9 and the elastic body 7 of the low-resilience urethane foam alleviates the mutual difficulty and can provide a comprehensive and comfortable feeling of use.

  FIG. 7 shows an example of fillers 306a to 306c that fill the small compartments 305a to 305c having shapes different from those described above. In the small compartments 305a to 305c shown in FIGS. 7A to 7C, fillers 306a to 306c matching the shape of the respective small compartments are inserted to constitute a bedding. In the same manner as described above, any of the fillers 306a to 306c is filled in a cylindrical elastic body portion having an arbitrary length in the direction of the thickness of the futon and a gap portion provided so as to penetrate the elastic body portion. The heat insulation material feathers and the inner bag body that encloses the elastic body portion. The filling body 306c in FIG. 7C has a circular outer diameter, and is used in combination with a small compartment 305c partitioned into a hexagonal shape by a partition cloth material 302c as shown in the drawing (so that the cross-sections substantially coincide).

  In the configuration as described above, each filling body in the bedclothes may have different elastic characteristics of the elastic body portion in the inner bag body according to the arrangement position of the filling body. For example, if a filler using low-rebound urethane foam, which has higher elasticity than the peripheral part, is inserted and placed in the center where the body rests at bedtime, the body will not sink unnecessarily and a comfortable sleeping comfort can be obtained. . At the same time, in the longitudinal direction of the mattress, if a filling body using a low resilience urethane foam having a lower elasticity is inserted and arranged at a position corresponding to a body part such as a buttock protruding downward at bedtime, the user's body A comfortable sleeping experience can be obtained.

  Further, as a further developmental configuration, a further function can be added to the bedding by incorporating, for example, a sheet-like deodorizing layer containing activated carbon fine powder into the filler as described above. A thin plate-like functional sheet (not shown) having an appropriate function is incorporated as needed on the upper surface of the illustrated elastic body portion. In addition, a functional layer that is considered to have health benefits may be incorporated. Such a filling body including a functional sheet is mixed as a whole or at an appropriate ratio to constitute a bedclothing such as a down comforter. Functional sheets include charcoal sheets that contain activated carbon powder in a flexible sheet for absorbing odors, sheets that contain ceramic powder with a far-infrared effect, sheets that generate magnetic field lines, and others. It can be used, and a plurality of sheets can be used together and incorporated into the filling body 6. In addition, it is also conceivable to use these functional materials so as to be incorporated into the elastic body portion or the heat insulating material without being formed into a sheet shape.

Next, the form of the side structure of the mattress body of the present invention will be described with reference to FIG.
FIG. 8 shows a bottom view (back side) of the duvet 100 of FIG. The upper surface side is the same as that of the previous embodiment (see FIG. 1), and the illustration is omitted. In this embodiment, a protective cloth 11 is provided to cover the entire surface of one side of the duvet 100 having the same configuration as described above where the insertion port 5a is disposed. The protective cloth 11 may be fixed by sewing or the like, but in this embodiment, the duvet 100a is configured by being detachably attached with an appropriate fastener 12. As the locking means, a fastener such as a hook-and-loop fastener, a hook, an American hook, and the like can be considered, and discretely along the bottom side peripheral edge to the corresponding portions of the mattress main body 100a and the protective cloth 11 along the bottom side peripheral edge. Install. With such a configuration, it is possible to easily replace only the portion of the filler whose elasticity has been locally deteriorated during the period of use, so that the repairability is improved and it can be used over a long period of time. Is preferred.

  In addition, although not shown in the drawings, the protective cloth 11 as described above is partially fixed to the main part of the down comforter, and the remaining peripheral part can be freely closed as required by using a fastener or the like. In this case, the repairability is improved as well. For example, as shown in FIG. 9, a slide fastener 114 is provided on two sides of the opening on a protective cloth 111 that covers the entire surface of the feather mattress 100b on which the filler insertion opening is disposed, and the opening 113 can be opened and closed freely. Configure. If two fastener sliders 114a are provided and moved in the center direction from both ends of the cut, the slide fastener 114 is closed, which is convenient. In this embodiment, the final assembly of the duvet is to seal the opening 113 by closing the fastener 114 by placing the elastic body portion into the small compartment of the bag body from the closed portion provided on the bottom surface. Complete with. With such a configuration, it is possible to easily replace only the portion of the filler whose elasticity has been locally deteriorated during the period of use, so that the repairability is improved and it can be used over a long period of time. Is preferred. The above-described protective cloth 111 is partially fixed to the feather mattress, but besides this, the protective cloth 111 itself is fixed to the mattress on all four sides. A part of 111 may be configured to be openable as necessary.

Below, the structure of the mattress which has the protective cloth 111 of the said structure is demonstrated in detail. 9, 10 and 11 are bottom views showing the back surface of the down comforter 100b.
As shown in the figure, the down duvet 100b has a protective cloth 111 which is fixed to the bottom side of the main part of the down duvet and provided with an opening 113. That is, an incision 115 continuous in an L-shape is provided along one short side and one long side of the protective cloth 111 on the lower surface of the down comforter 100b, and a slide fastener 114 is attached along the notch 115 over the entire length. Yes. The fastener 114 can be closed at its full length from both ends of the cut 115 by two runners 114a and 114a as appropriate. In the normal use state, the filler 6 is accommodated in the small compartment 5 and the slide fastener 114 is closed (FIG. 9), but the slide fastener 114 is released to both ends as shown in FIG. 10 as necessary. If this is done, the central portion of the bottom surface opens greatly as the opening 113, and the filler 6 can be easily taken out from the small compartment 5 through the insertion port 5a and replaced with a new one. In this way, the opening 113 of the protective cloth 111 is formed with an incision 115 that is continuous in an L shape along one short side and one long side of the lower surface of the down comforter 100b, and the entire length of the incision attached along the incision 115. It consists of a slide fastener 114 that can be closed. In addition, it is also possible to adopt a configuration in which the hooks are discretely arranged along the opening other than the fastener.

  FIG. 11 is a bottom view showing the back surface of a down comforter 100c of still another embodiment. This embodiment is substantially the same as the down comforter 100a shown in FIG. 8, except that only the filler 6 is arranged on the entire surface without using the edge cloth 4 on the outer periphery. The other parts are the same and will not be described.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made. For example, in the embodiment, only the case where adhesion is used to form the bag-shaped side ground has been described. However, the same applies to the case where sewing is used for bonding, and centering and dimensioning at the time of sewing are not necessary, and the corresponding man-hours A reduction effect is obtained. Moreover, although embodiment of the futon which formed the hexagonal shape (tortoise shell pattern) small compartment was demonstrated, the planar shape of the small compartment in this invention is not restricted to this. For example, a lattice-shaped small compartment may be used, and a skewed quadrangle (diamond) or other patterns may be employed. If you print on the surface of the front side surface the design that clearly shows the shape position of the small compartment corresponding to each case, you can manufacture a down comforter with almost the same work procedure described above, for direct feather filling like the conventional one In combination with the use of a filler, the number of man-hours can be significantly reduced, leading to cost reduction. A composite material filling body having a shape corresponding to the planar shape of the small compartment is combined and filled together.

In the down comforter of the present invention, a partition is provided between the members, and the partition material is sewn or fused, and the upper and lower fabrics are fixed, so that the shape is firmly maintained against the impact during use, and deformation and distortion are instantaneously performed. By having the function of correcting, the feeling of comfort is dramatically improved, the comfort of sleeping is improved, and the durability is remarkably improved. If a design that clearly shows the position of the small compartment is printed on the surface of the front side fabric, a down comforter can be easily manufactured by bonding, and this is combined with the use of a filler instead of the conventional direct down filling. Therefore, the man-hours can be significantly reduced, and the cost can be reduced. Further, by appropriately selecting the material of the filler, it can be used not only for duvets but also for mattresses and the like.
