Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a duvet. In particular, the present invention relates to a duvet having a crosslinked cloth that separates the inside of the futon so that the filled feather does not move, wherein the duvet is bonded with an adhesive.

[0002]

[Prior art]

 Conventionally, in the duvet, the coupling and friction between the feathers are small, and the feathers filled in the duvet are easily moved in the duvet bag and are easily unevenly distributed. It is necessary to fractionate the interior of the futon into several small parts. In addition, this separation cannot be prevented by simply stopping the futon lining between the outer surface of the futon and the lining of the futon with a thread so that the movement of feathers cannot be prevented. Conventionally, a cross-linked cloth has been provided between the outer surface of the futon and the lining of the futon for the fractionation. In the detailed description of the present invention, the duvet of the present invention will be described in a state where the futon outer material is always located on the upper surface and the futon lining is always located on the lower surface. Therefore, for example, the vertical plane is a plane perpendicular to the surface of the futon surface and the futon lining. The cross-linked fabric used for this duvet fractionation was initially sewn to the futon fabric and lining with a thread, but the appearance of the thread on the surface of the futon fabric is poor and disliked by consumers. There were drawbacks, as well as defects such as mites entering through the holes in the cloth and propagation, and defects such as minute pieces of feather falling out of the holes in the thread. In order to solve this drawback, there has been disclosed a futon in which a cross-linked cloth is bonded to upper and lower face cloths with an adhesive so that thread does not appear on the surface of the futon cloth (Japanese Patent Laid-Open No. 62-87186). ). However, since the structure of the crosslinked fabric according to this method has a cross-sectional structure as shown in FIG. 7, there is a disadvantage that the crosslinked fabric 1 is easily mechanically peeled off from the joining surface end m by the tension applied to the crosslinked fabric 1. Actually, the peeling force of several times or more the tension applied to the crosslinked cloth is concentrated at the position of the end m of the bonding surface in FIG. 7, so that the crosslinked cloth 1 easily peels off from the futon lining 8. Next, in order to improve this drawback, a cross-linked fabric disclosed in JP-A-5-42029 (Japanese Patent Publication No. 6-49015) has been proposed. As shown in FIG. 6 (a), the structure of the crosslinked cloth is such that the crosslinked cloth 1 is sewn to the center of the adhesive cloth n which is joined to the futon outer material and the futon lining 8 with the adhesive layer 6 by the thread 5. Structure. That is, in this cross-linking structure, only another adhesive cloth n is temporarily attached with the adhesive layer 6 without directly attaching the cloth for cross-linking to the cloth complex with the adhesive, and indirectly attached to the center of the adhesive cloth n. The end of the crosslinked cloth 1 is sewn. This is because, since the cross-linked cloth 1 is attached to the center of the adhesive cloth n, the tension applied to the cross-linked cloth 1 is evenly applied to both sides of the center mounting portion of the adhesive cloth n, so that the tension is not concentrated at one point, so that the bonding is performed. The cloth n is improved so as not to peel off. However, in the case of this cross-linked cloth, as can be seen from FIGS. 6 (a), 6 (b) and 6 (c), the tension applied to the cross-linked cloth 1 is pulled in a direction perpendicular to the thread 5 in FIG. It takes like. Thus, when there is a tension applied perpendicularly to the thread, the thread is very easily frayed. This tendency is particularly remarkable when the thread is a chain stitch that is usually performed. The crosslinked cloth having the structure shown in FIG. 6 is strong at the beginning of use, but has a drawback that the thread 5 is frayed and the crosslinked cloth 1 comes off from the adhesive cloth n during a long-term use, for example, after about one year of use. As a result, a defect in which feathers are unevenly distributed appears. Further, in the case of the cross-linking cloth of FIG. 6, the thread 5 in which the cross-linking cloth 1 is attached to the adhesive cloth n is seen through the futon surface or the futon lining, and has a disadvantage that the appearance is poor. In other words, the crosslinked fabric of FIG. 6 in which the strength defect of FIG. 7 has been improved has partially abandoned the original improvement of FIG. 6 of hiding the thread.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to completely eliminate both the drawbacks of the conventional duvet where threads are visible and the drawback that the crosslinked fabric comes off.

[0004]

[Means for Solving the Problems]

 According to the present invention, to achieve this object, the cross-linked cloth is formed as an integral structure, and two cross-linked cloths are superimposed so that the cross-sectional structure is symmetrical with respect to the cloth at the cross-linked portion. Glue that secures the double structure with the central part of the cross-linked fabric by sewing or adhesive, and opens both free edges outside of the double structure with double doors to join between the futon surface and the futon lining. It was a substitute. Then, a heat-sensitive adhesive was used for joining the glue sur- face and the futon. That is, in the present invention, in a duvet in which a duvet-like bag body in which a futon outer material and a futon lining are connected by a cross-linking cloth is filled with feathers, the cross-linking cloth has two rectangles having a width of 15 to 100 mm and a length of 30 mm or more. If the width of the fabric is kept perpendicular to the longitudinal direction by superimposing the above fabric, the sewing structure on the joining line provided in the longitudinal direction along the upper and lower edges at a distance of 1 to 15 mm from the upper and lower edges, or A central double cloth structure band is formed by fixing the inside of the joining line with an adhesive, and a pair of cloth edges above and below the joining line are laterally moved toward the cross section of the central double structure band. Another aspect of the present invention is to provide a duvet characterized in that the upper and lower sides of the glue sur- face are open and closed, and the upper and lower glue sur- faces are bonded to a futon surface and a futon lining with a heat-sensitive adhesive.

[0005]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a basic perspective view showing the structure of the crosslinked cloth 1 of the present invention. In FIG. 1, two elongated rectangular cloths each having a width B and a length X are superimposed, and the width direction is maintained vertical as shown in FIG. Along this, two rectangular cloths are fixed by sewing with thread 5. When the portion having the width A is opened horizontally in the left-right direction with the double-sided opening, the sectional structure shown in FIG. 2 is obtained. This corresponds to a perspective view of the shape of the crosslinked fabric in the duvet of the present invention. The width B of this rectangular cloth is 15 to 100 mm, preferably 20 to 60 mm, the length X is 30 mm or more, preferably 50 to 2200 mm, and the width A of the glue margin surface is 1 to 15 mm. Preferably it is 3 to 8 mm. The width B is appropriately determined by the thickness of the futon to be applied and the width A of the glue margin surface 3. If the width A of the adhesive margin is narrow, the adhesive strength is reduced, but if it is too wide, the feel of the duvet becomes poor. The length X of the crosslinked cloth is 30 mm or more, preferably 50 to 2200 mm, and the length is appropriately selected according to the mode of fractionation of the futon. A double structure 2 is provided at the center of the cross-linked cloth 1 in FIG. 2, and adhesive glue surrogates 3 and 4 extending horizontally are formed above and below. As another embodiment of the present invention, as shown in FIG. 2, instead of sewing a double-structured cloth with a thread, the inside of the position of the two threads is bonded with an adhesive to form the same double structure. Can be used instead of the crosslinked fabric of FIG. The adhesive used in this case may be a heat-sensitive adhesive, a pressure-sensitive adhesive, or other known adhesives. In particular, the adhesive is used in the final thermocompression bonding step of joining the crosslinked fabric to the fabric. A thermosetting adhesive is desirable to prevent it from melting and coming off. The crosslinked fabric of the present invention is obtained by applying a heat-sensitive adhesive to the upper and lower adhesive margin surfaces 3 and 4 and joining the upper and lower futon outer fabric and the inner surface of the futon lining with the adhesive to crosslink the crosslinked fabric. The inside of the futon is fractionated with a cross-linked cloth. FIG. 3 is a cross-sectional view showing a state in which the upper and lower futon linings and the futon lining are connected by a heat-sensitive adhesive. FIG. 3 is a sectional view taken along line dd of FIG. As shown in FIG. 3, the adhesive margin surface 3 and the futon surface material 7 are joined via a heat-sensitive adhesive layer 6.

In this case, the tension applied to the upper and lower futon outer material and the futon lining is applied to the double structure 2 of the crosslinked cloth. This tension is applied to the upper and lower futon outer surface, the futon lining, and the bonding surface of the cross-linked cloth, and the tension is uniformly applied to the left and right sides of the vertical cross section of the double structure 2. In addition, the bonding surface of the adhesive margin surface 3 does not peel off. In FIG. 6, the tension applied to the cross-linked cloth is applied perpendicularly to the thread 5 sewing the cross-linked cloth and the bonding cloth before being applied to the joining surface between the adhesive cloth and the futon. Therefore, the thread 5 may be frayed and the crosslinked fabric may come off. On the other hand, the thread of the present invention forms a double structure by sewing the two cloths constituting the cross-linked cloth. No tension is applied between the linings. In particular, there is no stress applied vertically to the thread. Therefore, the thread of the present invention has a structure similar to that of the cross-linked fabric (FIG. 6) of Japanese Patent Application Laid-Open No. 5-42029 (Japanese Patent Publication No. 6-49015), no matter how much tension is applied between the futon surface and the futon lining. Never fray. Further, since the thread is sewn in a double structure and does not face the futon surface and the futon lining, the defect that the thread can be seen through the futon surface and the futon lining as shown in FIG. 6 is also improved. . It is apparent that the same effect as in FIG. 1 can be obtained when the double-structured cloth, which is another embodiment of the present invention, is bonded with an adhesive because no thread is present. As for the position of the fraction of the duvet of the present invention by the crosslinked cloth, the fractionation method performed with the conventional duvet can be appropriately adopted. For example, it can be fractionated at the position shown in FIG. 4 (a) or (b). For this fractionation, the operation of joining the crosslinked cloth of the present invention between the outer surface of the futon and the lining of the futon is performed, for example, by connecting the crosslinked cloth of the present invention between the glue surfaces 3 as shown in FIG. 5 (a) or (b). Apply heat-sensitive adhesive to the upper and lower glue sur- faces formed by folding the double structure 2 and place it between the futon lining and the futon lining. It can be pressed to form a crosslinked structure. FIG. 5A shows a shape in which the center of the double structure 2 is folded right and left when the portion of the double structure 2 is formed by sewing. FIG. 5B shows a shape in which the double structure 2 is folded into a lightning bolt, and can be applied to a case where the double structure 2 is formed with a thread or an adhesive. Further, regardless of the double structure, thermocompression bonding can be performed in a state where the double structure is stretched as it is in the state of FIG. In this case, the position of the futon lining and the futon lining are shifted in advance by the length of the double structure to prevent the futon lining and the futon lining from shifting, and to prevent the cross-linked cloth of the duvet from inclining. be able to . However, even if the cross-linked cloth of the present invention is slightly inclined, the effect of fractionation and the performance of the futon are hardly affected. In the present invention, a heat-sensitive adhesive is used for the adhesive margin surface 3. In the present invention, the adhesive is a heat-sensitive adhesive during the operation of forming the cross-linked structure for fractionation inside the futon, so when the operation for aligning the fractions is performed at room temperature, the adhesive becomes Or, since it does not stick to the wrong position of the futon lining, it can be adhered to the correct position of the glue surrogate surface 3 and the futon outer material 7 or the glue surrogate surface 4 and the futon lining 8. The heat-sensitive adhesive used in the present invention is, for example, a layer of a thermoplastic resin that is melted by heat, a thermosetting resin that is cured by heat, or the like, or a resin tape is stuck to the adhesive margin surface and then thermocompressed. Can be used without any particular limitation as long as it is possible. Preferably, a layer of polyester resin, nylon, or polyurethane resin or a tape-shaped layer of these resins is used. In this way, the duvet of the present invention can be manufactured by uniformly filling each of the divided portions of the futon bag between the futon lining and the futon lining with the crosslinked cloth.

[Effect of the invention]

 In the present invention, there is a double cloth structure in the center of the structure of the cross-linked cloth, and there is a glue surface that is open to the double-sided opening with respect to the double structure surface at both end edges. Since the adhesive is applied to the bridge cloth to apply a uniform force to the left and right, the adhesive is strong. Further, since there is no thread for fixing the cross-linked cloth and the adhesive glue surplus surface, there is no disadvantage that the thread is unraveled and the cross-linked cloth comes off. Also, the use of a heat-sensitive adhesive makes it easy to attach the cross-linked cloth to the futon. Further, the present invention has a particularly effective effect for duvets, such as improving the defect that the thread can be seen through the surface of the futon or the lining of the futon, and is industrially useful.
