Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-layer futon having a two-layer structure filled with feathers, and more particularly to a structure which facilitates a process of forming a side lining, and facilitates a work of filling feathers into an internal small compartment. Related to the structure.

[0002]

2. Description of the Related Art Futons are generally filled with a filler such as feathers between the front and back fabrics (side fabric). In particular, in a futon filled with feathers, in order to prevent uneven distribution of the feathers and prevent the feathers from jumping out, a small compartment is formed inside between the front and back side grounds, and the feathers are filled therein. I have.

[0003] In many of such futons, a small compartment is formed by joining the outer material and the lining by sewing or the like, so that a small compartment having exactly the same shape and a joining line are formed on the front and back surfaces of the futon. Is formed. As a result, there is a problem in terms of function and design. That is, first, since no middle material such as feathers or batting is located at the joining line portion, hot air easily escapes therefrom, and the inside hot air escapes outside at bedtime, which is a negative factor for heat retention.

[0004] In these futons, only bonding lines of exactly the same shape and no change in position appear on the front and back surfaces. Even if the futons are turned over, they have the same appearance. It was a form lacking.

[0005] Incidentally, since the thermal insulation characteristics of the duvet change due to an excessively large amount or composition of the down duvet, in order to solve the problem of the thermal insulation, it is conceivable to simply increase the filling amount of the middle material such as down or batting. However, such a configuration has significant downsides such as an increase in the futon mass and an increase in the price of the product, and is actually difficult to employ. In addition, for example,
Japanese Patent No. 49015 (Fabric grounding method and futon: hereinafter referred to as Proposal 1) discloses a futon in which a partition is formed by using a partition wall cloth. The same pattern appears.

[0006] As another example of the structure that solves the above-mentioned inconvenience in heat insulation performance, for example, Japanese Utility Model Publication No. 2-1095 (double structure duvet: hereinafter referred to as proposal 2) employs a two-layer structure. A duvet is disclosed and shown in equivalent plan and longitudinal section in FIG. The publication discloses two bag-like bodies (50) each of which is filled with feathers (53) in a plurality of sections between the front and back cloths (51, 52).
A, 50B: futons) have been proposed in which the positions of the lane markings (54, 54 ': quilting) are shifted from each other on the front and back sides by an amount corresponding to the width of the quilting, and are integrally fixed.

The bag-shaped members (50A, 50B) are connected to each other at an appropriate distance by a connecting thread (56). Further, the peripheral edges are joined by an edge cloth (57). As a result, the lane marking (quilting) portion on one side overlaps with the feather layer on the other side, so that a sufficient heat retaining effect can be obtained even at this portion, and the overall heat retaining characteristics are improved. In addition, in the description of the proposal, description regarding filling of feathers in each section is omitted,
The filling port and the like are not particularly described.

[0008] In addition, if two futons having different outer peripheral shapes in the joining line (quilting) pattern are prepared in accordance with the technique of the already proposed 2 and the two futons are drawn up into two layers, the quilting is used upside down. Thus, it is possible to obtain a reversible futon with a meaningful design.

[0009] However, the two-layer futon disclosed in the above-mentioned proposal 2 has a drawback that it requires many steps for its production and the production cost is high. That is, two independent single-layer duvets
After completing the same number of pieces, pay careful attention to both and use the splicing thread (56)
Then, the peripheries of the front and back two layers are further joined by the edge cloth (57) to complete the futon. In the meantime, a large amount of labor is required to join large bag-like bodies that are extremely difficult to handle after filling with feathers at the center portion or to join the entire periphery, which naturally affects the price.

In addition to the above techniques, for example, Japanese Patent Laid-Open No. 7-246146
Japanese Patent Laid-Open Publication (hereinafter referred to as Proposal 3) discloses a two-layer futon by the present applicant. FIG. 8 is a side sectional view,
FIG. 9 is a partially cutaway plan view. This futon has two layers (bag: 10A, 10A) by bonding (joining) the outer material (11) and the lining (12) from both sides of a single core material (17 ').
A number of sub-compartments (2, 2,...) Which have become B) are formed, and each sub-compartment is filled with feathers (1).

[0011] The joining lines are in a lattice shape, and the individual joining portions (adhesive layers) are provided in a straight line. The thermocompression bonding device (30) having a long linear heating portion as shown in FIG. Interlining (17
′) And the outer material (11) or the lining (12) are adhered. Each reference numeral is assigned in accordance with the already proposed method 3, and the description of each unit is omitted here. The small compartments on the front and back are formed so as to be shifted from each other, thereby eliminating a portion having a small amount of feathers and improving heat retention. Outer fabric and lining at the edge (16)
It is joined by.

However, in this example futon (20 '), the pattern shown by the joining line (14) on the front and back is different, but both are grid patterns, and have a similar appearance even when turned upside down. But the design effect is still low.

In the proposal, each of the small compartments (2,
2, ...) to fill feathers by leaving a part of the joining line (14) and joining the non-joined part (gap) to fill the opening (2a
′), The filling nozzle (21) is allowed to reach the small compartment from outside through the filling opening gap, and feathers (1) are blown in for filling. Similarly, a series of small compartments is sequentially filled with feathers. It has become. However, since the filling opening (2a ′) for filling remains as it is and is not specially designed to be closed, the filling opening is usually narrowed, but the opening is opened depending on the state of the futon. As a result, during a long period of use, feathers (1) moved between the small compartments, resulting in uneven distribution of the feathers, resulting in a worsening of usability in a few cases.

[0014]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to solve the inconvenience generally seen in a two-layer duvet excellent in heat insulation, that is, to use one of the duvets. To surely prevent the movement and uneven distribution of feathers between small compartments that deteriorate the feeling, and to obtain a suitable duvet by using for reversible use with high designability with different joining patterns on both sides, It is another object of the present invention to propose a duvet having a novel structure and a two-layer structure, which is intended to reduce the manufacturing cost.

[0015]

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION

[Embodiment] Hereinafter, a two-layer futon of the present invention will be described in detail with reference to the accompanying drawings based on embodiments. Each figure of FIG. 1 is a diagram showing one embodiment of a two-layer futon (duvet) of the present invention, FIG. 1 (a) is a side sectional view, and FIG. FIG. 1 (c) is an enlarged plan view for explaining the filling port.

The duvet (20) shown in the figure has two cores (17A, 17B) at the center in the thickness direction, and the outer core (11) and the lining (12) is bonded along the bonding line to form a two-layered front and back bag-like body forming a plurality of small compartments (2, 2, ...), and each small compartment (2, 2,
…) Are filled with feathers (1) to form a two-layer structure.
The core interlinings (17A, 17B) are joined to each other by stitching except for the non-joining portion (3), so that the two layers do not significantly deviate. As described later, the filling pipe (4) can be inserted into each of the small compartments (2, 2,...) From the outside through the non-joining portion (3) to fill the feathers.

The futon of the embodiment employs a configuration excellent in appearance and function without applying any sewing marks to the outer surface by employing adhesive for the main part of the joint. Hereinafter, each part will be described in consideration of the manufacturing process (processing order) in the embodiment.

First, the center interlining will be described in detail. The two cores (17A, 17B) have substantially the same planar shape, and a non-woven fabric or a knitted fabric is used as a material. Filling ports are provided at appropriate positions respectively corresponding to all of the small compartments (2, 2,.
(18) is provided. That is, a slit is formed as an opening (18 ') in the center interlining, and this slit (18')
On one side (the inner surface of the bag), a cloth-like closing piece (19) covering the slit is joined (sewed) to the core fabric at the edge except for the opening edge (sewing portion: 19a).

It is to be noted that closing pieces (19) may be provided on both sides of the slit. However, it is possible to omit the closing piece by providing a slit at a position shifted from each other in the two cores, and when completed as a futon, the feather filled in the small compartment room When pressed, one of the cores is covered with the slits of the other core, so that the movement of the feathers is sufficiently suppressed in practical use.

A thermosetting adhesive layer is provided in a strip shape along the joint line (14) corresponding to the intended partition pattern on the same core interlining. In this case, it is preferable to sew a band-shaped cloth material prepared in advance at a predetermined position similarly to the technique disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 7-246146. That is, a thermosetting (or thermosoftening) adhesive is applied or impregnated onto one surface of a band-shaped base cloth of a predetermined width made of a nonwoven fabric or the like, and a band-shaped cloth material whose adhesive side is covered with a protective tape is bonded. The band-shaped cloth material is sewn to the center interlining (17) at the center in the width direction of the band-shaped cloth material with the agent side surface facing outward. In addition, the protective tape for preventing adhesion of dust
It is removed immediately before the subsequent bonding process (heating).

The band-shaped cloth material is sewn to a predetermined portion so that a shape defined by a joining line determined by sewing has a desired continuous pattern such as a hexagon. As will be described later, if a thermocompression bonding roller device is used for bonding, it is possible to combine the patterns including a curve such as a circle. The outer fabric (11) or the lining (12) is joined according to the joining line (14), and the plurality of small compartments (2, 2, ...) are divided. And, as described above, at least one filling port (18) is provided in each sub-compartment, corresponding to a plurality of sub-compartments formed later by being bonded to the outer material (lining). It is.

The arrangement of the joint lines (14) of the two core interlinings may be of the same position, of course. Performance can be improved. Furthermore, a completely different pattern can be selected as the partition pattern of each layer on the front and back sides to provide a reversible product having a rich design. For example, even if similar squares are used on the front and back sides, if the sizes are different on the front and back sides, a product that is attractive in design can be obtained.

The above-mentioned core fabrics (17A, 17B) are joined back-to-back at joints (15) with the above-mentioned adhesive surfaces facing outward. The joining is achieved by suturing the appropriate site. At this time, the non-joined portion (3) (which easily deforms and forms a gap) is joined between the two core interlinings so as to reach all the small compartments (2, 2, ...) from the outer periphery. Be careful. For example, joints discrete at appropriate intervals
In (15), the pieces are joined by sewing or bonding in a point-like manner, or are joined in a linear or belt-like manner so as to leave a band-like portion including a filling port group provided in a line from one outer side. The non-joined part
At (3), a filling pipe (4) passes through during the later feather filling operation.

The above member has a surface material (11) and a lining (12) from both sides.
Are bonded by bonding to form small compartments (2, 2,...), And the side ground is almost completed. The use of a thermo-compression roller device having a heat roller having a width corresponding to the width of the side ground can greatly reduce labor. That is, the outer material (11) and the lining (12) of the same planar shape are simply superimposed on both sides of the above-mentioned member, and are fed between the heat rollers maintained at a predetermined temperature above and below the thermocompression roller device while keeping this state integrally. It is sufficient that the adhesive is passed sequentially, and the adhesive of the above-mentioned band-shaped member is melted by heat and then hardened, and the whole is adhered in one step, whereby the intended small compartment is formed at a time. Regarding the peripheral portion, for example, leaving one side as a filling opening side and attaching and sealing an edge cloth, filling the small compartments (2, 2, ...) with feathers and sealing the entire periphery, or a central small compartment After filling with the feathers, the small compartment at the peripheral edge is sealed with an edge cloth while filling with the feathers.

The interior of the small compartment (2, 2,...) Is filled with feathers. Filling is performed by inserting a filling pipe into each of the small compartments from the opening edge of the filling port through the gap (the above-mentioned non-joined portion) between the cores at least in each central compartment. This can be easily performed by blowing an appropriate amount of feathers from the outside. After the filling is completed, an opening side or the like communicating with the outside is sealed by an appropriate means. After the feathers are filled, the closing pieces (19) covering the openings (18 ') are pushed by the feathers so as to closely adhere to the core material and to close the openings (18') reliably, so that the feathers in each of the small compartments are closed. Does not go out at all, and uneven distribution of feathers does not occur.

Other structures can be employed for the filling port. FIG. 2A is a plan view showing another filling port structure.
FIG. 2 (b) is a side sectional view at the corresponding YY 'portion. This filling port (18) is a slit (18) as an opening opened in the core at an appropriate position corresponding to all small compartments.
′) And a cloth-like / rectangular closing piece (19) provided on both sides so as to cover the slit, and the closing piece (19) is sewn to the core fabric (17) at the opposite side ( Sewing portions: 19a, 19a), and the remaining sides are opening edges. Therefore, the tip of the filling pipe (4) can be inserted into the small compartment from the opening edge through the slit (18 ') from the outside. After the feathers are filled, there is the obstruction piece (19), so that the feathers inside the small compartment room do not go outside and the feathers move as the whole futon but are not unevenly distributed. The closing piece may be formed only on one side of the slit (18 ') (preferably on the inner side of the bag).

The filling port can be further simplified, and even if a simple structure in which a slit or a round hole is formed as an opening in the core material without providing a closing piece, two core materials can be formed after filling. Since the feathers are pressed by the filled feathers and come into close contact with each other and close each other, there is almost no movement of the feathers.
A structure without an obstruction piece is sufficient for practical use. Of course, it is preferable to provide the closing piece, because the effect of preventing feather movement is more reliable.

Since the futon of the embodiment has the structure as described above, it also has several advantages as follows. That is, first, it is possible to manufacture a two-layer futon with good heat retention and a reversible futon with excellent design and high commercial value with less man-hour than before, and can supply it at low cost. In addition, it is possible to manufacture a very high design which combines a curved pattern or a complicated polygonal line with the shape pattern of the small compartment, and furthermore, by adopting a different pattern as shown in FIG. A futon that is expensive and favorable for consumers can be realized.

As the partition pattern (joining line pattern) of the small partition chamber, not only a simple continuous pattern of the same polygon but also a pattern in which these are combined in a complicated manner can be easily obtained. FIG. 4 shows an example of such a pattern. In the duvet shown in FIG. 4 (only one-sided plan view), squares regularly arranged at regular intervals between octagonal small compartments (2 m, 2 m,...) Arranged regularly in all directions. The small compartments (2n, 2n,...) Are aesthetically arranged, which is different from the pattern of the conventional duvet. According to the present invention, such a complicated joint line pattern can be obtained with extremely short man-hours by employing the adhesive structure and the heat roller device. A design incorporating a circular partition is also possible.

In addition, a large number of semi-finished products (core portions) having only a core interlining portion are stocked in limited production types (see FIG. 3). The advantage that by preparing only the side part and combining it with the core to complete the side lands, it is possible to respond to various needs in detail, but at the same time, it does not require excessive material inventory and shortens delivery time There is also.

In the above embodiment, the cores are joined by stitching. However, if the joints are also fixed to the joints in a point-like or line-like manner by using the above-mentioned bonding technique, the total is fixed. The four members are prepared, stacked in a predetermined direction (surface), kept together, and passed through the thermocompression bonding roller device as they are, so that only one process is required for the side portion (two layers each having (different) small compartments). After that, the desired two-layer futon is completed only by filling the small compartments with feathers and sealing predetermined places.

By the way, the same two-layer futon can be obtained even if the core interlining is constituted by only one sheet. Next, this structure will be described. FIG. 5 is also a side sectional view showing one embodiment of the two-layer futon of the present invention, and FIG. 6 is a corresponding partially cutaway plan view. In the duvet (20A) of the second embodiment, only one core fabric (17C) is used.

For the rectangular core material (17C), a non-woven fabric or a knitted fabric is used as a material. In the center interlining, the band-shaped cloth material is placed at a predetermined position along the bonding line (14) corresponding to the intended partition pattern formed on the front and back surfaces in the same manner as in the previous embodiment, with the adhesive side surface outward and the width. After sewing at the center in the direction, the outer fabric (11) and the lining (12) on the opposite side are adhesively bonded by heating at this part,
A small compartment (2, 2,...) Of a predetermined shape is formed on both sides in a two-layer structure of bag-like bodies (10A) and (10B). From the viewpoint of the filling port to be described later, it is necessary to attach the joining line (14) on the front and back surfaces so that the small compartments on the front and back are offset from each other as shown in FIG. 6, for example.

Each of the small compartments (2, 2,...)
A filling port (18) is provided at an appropriate position so as to communicate with a small compartment (in most cases, two compartments) which overlaps on the opposite surface corresponding to each. Accordingly, at least two filling ports (18) are provided for each small compartment. The filling port (18) may be only one for the last small compartment along the filling direction. The filling port (18) has a structure in which a slit or a small hole is formed as an opening (18 ') in the center interlining, and the opening is covered with cloth on one side which is the inner surface side of the bag. The closing piece (19) is joined (sewn or adhered) to the core material in a valve shape leaving an opening edge. Aperture
(18 ') may be provided with blocking pieces (19) on both sides.

The side lining composed of the three members of the core interlining (17C), the outer material (11) and the lining (11B) is superimposed in consideration of the surface orientation, and is kept together and passed through a thermocompression roller device as it is. The assembly is completed in one process by heat bonding.

All the small compartments (2, 2,...) On the side ground have feathers.
(1) is filled. In the filling operation, as shown in FIG. 6, the opening (2a) is sequentially passed through a series of small compartments (2, 2,...) In which the filling pipe (4) is arranged in one direction from the opening (21) at one end of the side ground. The feather is blown into the leading compartment, and the filling pipe (4) is pulled out to the foremost (the opposite side) compartment, and the feather is filled into the compartment. The same applies to all of the series of subcompartments.
Fill (1). After the filling is completed, the opening (21) is sealed (joined).

In the structure of the present embodiment, there is a limit in improving the designability by combining a too complicated small compartment shape or a small compartment having extremely different shapes from the front and back due to the filling operation, but there is a limit to the ease of manufacture and the feathering. In terms of preventing movement and uneven distribution, the same effect as in the previous embodiment can be obtained.

In each of the embodiments described above, a case is described in which the minimum number of filling ports is provided. However, the same filling port is provided at least twice, and the filling operation is performed using one of the filling ports at the time of filling. The filling workability can be improved by providing the filling ports in an overlapping manner. In addition, the one using the closing piece at the filling port has an advantage that the filling port position can be easily confirmed from the outside during the filling operation and the filling pipe can be easily inserted.

[0046]

As described above in detail, according to the present invention, a two-layer futon is formed by joining the outer material and the lining from the outside to each of two core cores joined to each other while leaving a non-joining portion at the center in the thickness direction. It has a two-layer structure in which a plurality of small compartments are formed and each of the small compartments is filled with feathers, and one or more filling ports are provided at positions corresponding to the small compartments in the two cores. And both core interlinings are joined leaving the non-joining portion reaching all the sub-compartments from the periphery outside, and the core interlining and outer material and the other interlining and lining are The small compartments are formed by bonding along a joining line that defines a predetermined planar shape and are continuously formed in both layers, and all inner small compartments are filled with feathers through the filling port and edge small compartments. After filling the feathers in the painting room, the front and back layers were joined at the periphery, It is possible to reliably prevent the movement and uneven distribution of the feathers between the compartments, and the feeling of use is not deteriorated, and it is possible to obtain a duvet suitable for reversible use having high designability with different joining patterns on both sides respectively. At the same time, there are a plurality of useful effects that manufacturing can be facilitated and cost reduction can be achieved.

[0047] The filling port is provided in an opening provided in a core fabric,
In the configuration made of the cloth-shaped closing piece joined at the edge while leaving the edge of the opening in the inner core so as to cover one side or both sides of the opening, the effect of preventing uneven distribution of feathers is more reliable. Has the effect.

Further, the core and the outer material and the other core and the inner material are bonded by bonding along a bonding line having a predetermined plane shape in which the positions of the two core materials do not coincide with each other, and are shifted between the two layers. The formation of the continuous small compartments positioned at the same time has a known effect of making the heat insulation uniform.

The shape of the two-layered small compartments on the front and back sides is a repetition pattern of similar figures having different sizes on the front and back sides, or a repetition pattern of different shapes on the front and back sides. There is an advantage that a futon having a preferable appearance with excellent properties can be obtained.

Further, a two-layer futon is joined from the outside to a single core at the center in the thickness direction of the outer material and the lining to form a plurality of small compartments, and each compartment is filled with feathers. Have
The interlining and the outer fabric and the interlining and the lining are joined by bonding along a joining line that defines a predetermined planar shape, and the continuous small compartments are shifted from each other on the front and back surfaces of the interlining. 2 that communicates with the sub-compartment on the opposite side of the core at a position corresponding to each of the sub-compartments.
The above-mentioned filling port and a closing piece that covers the filling port are provided, and after all the small compartments are filled with feathers from the outside via the filling port, the front and back two layers are joined at the peripheral portion. With the simpler configuration, it is possible to reliably prevent the movement and uneven distribution of feathers between the small compartments as described above with a simpler configuration, and to obtain a duvet suitable for reversible use at a low price in an easy manufacturing process. be able to.

In particular, in each of the above-described configurations, after the adhesive layer is attached to the core material or the outer material and the lining by sewing or the like in advance, the core material, the outer material and the lining are overlapped and passed through a thermocompression roller device. If the small compartments are formed by bonding the interlining with the outer material and the lining, there is an effect that the manufacturing process can be further simplified and the cost can be reduced.

The outer material and the lining are joined from the outside to each of two core cores joined to each other while leaving a non-joining portion at the center in the thickness direction to form a plurality of small compartments, and each small compartment is filled with feathers. A two-layer futon having a two-layer structure, wherein the two cores leave an opening edge so as to cover one or both sides of the opening at a position corresponding to each of the small compartments. At least one filling port provided with a cloth-like closing piece joined at the edge to the ground is provided, and is pre-adhered along a joining line that defines a repetitive pattern of a mutually different shape on each core ground. A layer is provided, and the two core interlinings are back-to-back, and are joined except for the non-joining part reaching all the inner sub-compartments from the periphery outside, and the core interlining, the outer material and the lining are overlapped. Each part is adhered by passing through a thermocompression bonding roller device, and the small sections are continuously formed in both layers. After filling all the small compartments with the feathers from the filling port, the two-layer futon composed by joining the front and back two layers at the peripheral edge is a highly advanced design that is significantly open from the conventional product. It has a lot of advantages such as easy partitioning and low cost because it can surely prevent the movement and uneven distribution of feathers.
