Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is a perspective view illustrating a duvet according to the present invention, FIG. 2 is a cross-sectional view taken along line AA ′ of the duvet shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB ′ of the duvet shown in FIG. FIG. 4 is a plan view illustrating a position where a middle-layer duvet (third duvet) is arranged in the duvet according to the present invention. The upper-layer duvet is seen through to show the middle and lower-layer duvets. It was done. In these figures, reference numeral 1 designates a duvet of a triple structure composed of an upper duvet 2, an intermediate duvet 3 and a lower duvet 4, and the upper duvet 2 has a surface material 5 and an inner surface 6 Between the outer layer 7 and the lining 8, the lower layer of the lower duvet 4.
Are filled with feathers 11 between the lining 9 and the inner lining 10 and subjected to quilting to form a grid 12
Are formed.

The upper duvet 2 and the lower duvet 4
Are the same size, and are overlapped so that the boundary 13 of each compartment 12 formed in the upper duvet 2 and the boundary 13 of each compartment 12 formed in the lower duvet 4 intersect, The upper and lower layers are integrated by a slide fastener 15 sewn to an edge cloth 14 around the duvets 2 and 4.

The middle duvet 3 is smaller than the upper and lower duvets 2 and 4 and is sized to fit between the upper and lower duvets 2 and 4. Then, the upper and lower layers of the duvets 2 and 4 are fixed to the inner surfaces 6 and 10 so that the middle and upper layers of the duvets 3 and 4 can be fixed horizontally or vertically at positions corresponding to the feet or shoulders of the upper and lower layers of the duvets 2 and 4. The male side member 16 of the magic tape adhered by the hook of the male and female is sewn, and the female side member 17 of the magic tape (registered trademark) is sewn on both sides (the outer fabric 7 and the lining 8) of the middle duvet 3. The middle duvet 3 inserted between the upper and lower duvets 2 and 4 is attached to the male member 16 of the magic tape sewn to the inner surface 6 of the upper duvet 2 and the middle duvet. Duvet 3
And the male member 16 of the magic tape sewn to the inner surface 10 of the lower duvet 4 by being fixed to the upper duvet 2 by being hooked on the female member 17 of the magic tape sewn to the outer material 7 of FIG. It is secured to the lower duvet 4 by hooking on the female side member 17 of the magic tape sewn to the lining 8 of the middle duvet 3.

In this embodiment, the boundary line 13 of each compartment 12 formed in the upper duvet 2 and the lower duvet 4
A third duvet 3 smaller than the upper and lower duvets 2 and 4 is inserted between the upper and lower duvets 2 and 4 which overlap each other so as to intersect with the boundary 13 of each compartment 12 formed in the above. As a result, a large number of confined air chambers are formed between the upper and lower duvets 2 and 4 and the middle duvet 3 and are further sealed by the upper and lower duvets 2 and 4, so that the heat insulating effect is obtained. There are many air chambers in which warm air is held at the position where the air pressure is desired to be raised. In addition, the third duvet 3 is made smaller than the upper and lower duvets 2 and 4 so that only the position where the heat retaining effect is to be increased can be made into a triple structure, so that the amount of the feather 11 used can be saved. A further heat retaining effect can be obtained by using the same amount of feather 11 as used for the conventional duvet having a double structure. Furthermore, since the third duvet 3 is detachably fixed between the two duvets 2 and 4, it can be moved to a position where cold is felt and the position can be made into a triple structure. The same heat-retaining effect as a duvet having three layers can be obtained.
The upper and lower duvets 2, 4 are slide fasteners 1
5 can be separated by opening and closing, so that it can be used as a single sheet if necessary.

A compartment 12 filled with feathers 11 has cloths 5, 7, 10 which are the front of the duvet and cloth 6, which is the back.
8 and 9 were formed by direct sewing, but it is also possible to form a compartment 12 by quilting by heat welding using a thermoplastic synthetic resin adhesive. The doughs 5, 7, and 10 serving as front faces and the doughs 6, 8, and 9 serving as backs may be joined to form the locking compartments 12.

Further, as shown in FIG. 4, the magic tape is arranged on the corresponding surfaces of the upper and lower layers of the duvet so that the intermediate duvet can be fixed at the positions where the duvet of the middle layer is fixed in advance. Alternatively, they may be arranged in a lattice.

As the hooking means for detachably fixing the male and female members by hooking, a hook for fixing by fitting a concave member and a convex member may be used in addition to the magic tape. Alternatively, the duvet of the middle layer may be fixed to the duvet of the upper and lower layers by tying using a string instead of the hooking means. Further, the shape of the compartment may be a pentagon or a hexagon in addition to the square.

Embodiment 2 FIG. As a modified example of the above embodiment, the slide fastener may be provided on one side vertically and horizontally. In the present embodiment, the upper and lower duvets 2, 4
Cannot be separated because the other side is sewn on the vertical and horizontal sides. The edge of the other side may be sewn directly, or may be sewn via an edge cloth.
