DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quilt mattress which can be folded in four without being bulky.

[0002]

2. Description of the Related Art In recent years, a relatively hard mattress using a hard material (hard cotton) obtained by solidifying polyester or the like in a plate shape, and a relatively soft and thick mattress have been widely available. The most common one is shown in FIG.
As shown in the figure, there is a mattress 61 in which a pattern is appropriately formed on the surface with a suture line 62.

[0003] The mattress 61 is appropriately folded three to four times and stored in a closet or the like, but it cannot be folded neatly because there are no folds.

In order to simplify this folding, FIG.
As shown in FIG. 5B, a quilt mattress 71 formed with two foldable suture lines (quilts) 72 and 73 extending at equal intervals in the horizontal direction, and similarly, as shown in FIG. As described above, three folding suture lines 82 to 8 are arranged at equal intervals in parallel.
The quilt mattress 81 that formed the No. 4 came to be used. These quilt mattresses 71, 81
By folding at 2,73,82,83,84 as folds, the vertical width can be reduced to 1/3 to 1/4, but since there are no vertical folds, the horizontal width is reduced. I couldn't. Therefore, the width is 10
Wide mattresses exceeding 0 cm may not be able to be stored compactly in a general closet.

Therefore, as shown in FIG. 5D, one horizontal suture line 92 serving as a horizontal fold and two vertical suture lines 93 and 94 serving as a vertical fold are formed. The formed quilt mattress 91 has been proposed. According to this quilt mattress 91, after being folded in half at the suture line 92, it can be further folded in half at the suture lines 93 and 94, and the width in the vertical and horizontal directions is reduced to about half before folding. can do.

[0006]

However, in the case of a hard mattress or a mattress having a thickness of about 5 to 12 cm, the structure shown in FIG.
Even if four folds are made from the positions 2 to 94, as shown in FIG. The reason that the futon bulges round and the corners jump up is that when the mattress is folded four times, there is a difference in the length between the outermost bent part and the inner bent part It is. In this state, even if it is folded four times, the height will be increased this time, and it will be impossible to store a plurality of mattresses in the storage space of the current closet.

Accordingly, an object of the present invention is to provide a quilt mattress that can be easily and neatly folded into four pieces without increasing the length.

[0008]

In order to solve the above-mentioned problems and to achieve the object, the quilt mattress according to the present invention forms a first suture line along a first folding center line of the quilt mattress, and the first suture is formed. At least one second suture line is formed on one of the quilt mattresses at the line along the second fold center line orthogonal to the first fold center line, and the first suture line is formed at the boundary. On the other side of the quilt mattress to be formed, at least two third suture lines sandwiching an extension of the second suture line are formed along the second folding center line, and the quilt mattress is folded twice at the first folding center line. Further, the second suture line is positioned at the middle of the third suture line in a state where the second suture line is bent inside the second folding center line with the second suture line inside.

[0009]

[Function] The first quilt mattress along the first folding center line
Fold it together at the suture line and overlap.

[0010] Next, the quilt mattress folded in half is bent at the second folding center line with the second suture line inside, and is folded in four.

The second suture line folded inward in this manner is sandwiched between the third suture lines located on the outside, and the arc length between at least two third suture lines is equal to the second suture line. Longer than the arc length centered at.

As a result, the quilt mattress does not swell greatly and the corners are unlikely to jump up.

【Example】

Next, a first embodiment of the present invention will be described with reference to FIGS.
Description will be made based on (d). In the present embodiment, a center line extending in the vertical direction through an intermediate point of the width of the quilt mattress 1 is defined as a first folding center line 6 for first folding twice. In addition, a center line extending in the horizontal direction through the center in the vertical direction of the quilt mattress 1 is referred to as a second folding center line 8 for further two-fold folding.

The quilt bedding 1 has one first stitching line 7 for sewing the front and back fabrics in the vertical direction. The first suture line 7 is formed on the first folding center line 6.

In the right half 3 of the quilt bedding 1 bounded by the first suture line 7, two third suture lines 11 and 12 are provided at predetermined intervals so as to sandwich an extension of the second suture line 9. And are formed in parallel. The interval between the third suture lines 11 and 12 is set to increase as the thickness of the quilt mattress 1 increases. Each of these suture lines 7, 9, 11, and 12 is formed in a wavy line, but is not limited thereto and may be formed in a straight line.

The quilt mattress 1 is folded in four as follows. First, from the unfolded state shown in FIG. 1A, the left half 2 of the quilt bedding 1 is bent at the first suture line 7 and overlapped with the right half 3 to form the two-folded state shown in FIG. To

The second folded state shown in FIG.
Second half of the lower half 4 of the quilt bedding 1 with the suture line 9 inside
By folding at the folding center line 8 and overlapping the upper half 5, a four-fold state shown in FIG. 1C is obtained.

Thus, the left half 2 of the quilt bedding 1 is
As shown in FIG. 1 (d), the right half 3 of the quilt mattress 1
And the arc length between the two third suture lines 11 and 12 is longer than the arc length around the second suture line 9, and the second suture line 9 is just the third suture line 11. , 12.

As a result, the quilt bedding 1 is not greatly expanded at the third suture lines 11 and 12 and the corner portions 13 are not swelled.
Is also difficult to jump.

A second embodiment will be described with reference to FIGS. 2 (a) to 2 (c). However, substantially the same components as in the first embodiment are shown in FIG.
2 are given the same reference numerals as those given in FIG.

The quilt bedding 21 is used for the first suture 7
Two second suturing lines 19 and 20 sandwiching the second folding center line 8 are formed in the left half 2 at the boundary.

Further, two third suture lines 24 and 25 are formed in parallel so as to sandwich an extension of the second suture lines 19 and 20 from both sides. The interval between the third suture lines 24 and 25 is the second suture line 1
It is wider than the interval of 9,20.

This quilt mattress 21 is folded in four as follows. First, as shown in FIG. 2B, the left half 2 of the quilt bedding 21 is folded twice at the first suture line 7 and overlapped with the right half 3. Next, as shown in FIG. 2C, the lower half 4 of the quilt mattress 21 folded in two
Is further folded in two with the second suture lines 19 and 20 inside, and overlapped on the upper half 5. At this time quilt mattress 2
The left half 2 of 1 is centered on the second folding center line 8 and 2
The right half 3 of the quilt bedding 21 is slightly larger at the two third suture lines 24 and 25 about the second folding center line 8 at the second second suture lines 19 and 20. Can be bent in an arc. As a result, the inner second suture lines 19 and 20 are located in the middle of the outer third suture lines 24 and 25.

As described above, in the quilt bedding, the left half 2 coming inward can be made to have a short bending length at the second folding center line 8 because the interval between the second suture lines 19 and 20 is narrowed, while the third suture line 24 is formed. , 25 are widened, so that the outer right half 3 can have a long bending length at the second folding center line 8. As a result, even thicker mattresses can easily
It is possible to fold.

FIGS. 3A to 3C show a third embodiment of the present invention.
It will be described based on. In this embodiment, the quilt mattress 3
A center line extending in the horizontal direction through the center in the vertical direction is a first folding center line 36 for first folding twice.
The center line extending in the vertical direction through the center in the horizontal direction of the quilt mattress 31 is referred to as a second folding center line 38 for further folding the quilt bedding 31 in two.
