Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a pine tress with an improved exterior structure.

[Technical background of the invention and its problems]

Generally, a mattress is constructed by polymerizing elastic bodies on the upper and lower surfaces of a spring unit, and covering these polymers with an exterior fabric.

Conventionally, the above-mentioned exterior material has an upper mirror material covering the upper side of the spring unit, a lower mirror material covering the lower surface side, and the upper and lower edges are sewn to the periphery of the upper mirror material and the lower mirror material to form the outer peripheral surface of the spring unit. It consists of a town area that covers the area. However, when the exterior fabric is divided into three parts in this way, the patterns of the upper mirror area and the gusset area, which are particularly noticeable in appearance, are discontinuous, resulting in poor appearance.
Furthermore, in the past, both the upper and lower mirror bases were each connected to a spring unit using flange cloth to prevent the exterior base from shifting. That is, one end of the flange cloth is sewn to each mirror base, and the other end is connected to the spring unit. As a result, the seams of the flange cloth were visible on the top surface, resulting in an unsightly appearance. Furthermore, since the seam between the upper mirror area and the upper edge of the gusset is often rubbed, this seam is likely to fray.

[Purpose of invention]

The purpose of this invention is to provide a pine tress in which the exterior pattern on the upper surface side of the spring unit and the surrounding area is continuous, the seam of the flange cloth is not visible on the upper surface side, and the exterior material is difficult to fray. .

[Summary of the idea]

This idea covers the lower elastic body provided on the bottom side of the spring unit with a lower surface, covers the upper elastic body provided on the top side with an exterior body, and bends the peripheral part of this exterior body. In this mattress, the outer peripheral surface of the spring unit is covered, the peripheral edge thereof is sewn to the peripheral edge of the lower mirror base, and the lower mirror base is further connected to the spring unit by a flange cloth.

[Example of idea]

An embodiment of this invention will be described below with reference to FIG. The mattress shown in FIG. 1 is equipped with a spring unit 1. This spring unit 1 has a large number of coil springs 2 connected to helical wires 3
are connected in a matrix. Further, an upper elastic body 4 and a lower elastic body 5, which are slightly larger than these surfaces, are joined to the upper and lower surfaces of the spring unit 1, respectively. An exterior body 6, which is sufficiently larger than the upper surface of the spring unit 1, is mounted on the upper surface of the upper elastic body 4 via an inner cloth 5a. Above inner cloth 5
The periphery of a is connected to the coil spring 2 located at the periphery of the spring unit 1 by a clip 7 so as to wrap around the periphery of the upper elastic body 4. Therefore, the upper elastic body 4 is prevented from shifting on the spring unit 1 by the inner cloth 5a. The exterior body 6 also has a knot 10 of cotton, feather, etc. between the inner cloth 8 and the outer cloth 9.
In addition, the inner cloth 8 and the outer cloth 9 are integrally quilted, and the peripheral portion is bent to cover the outer peripheral surface of the spring unit 1.

On the other hand, on the lower surface of the lower elastic body 5, a lower mirror 11 is provided.
are joined. One end of the flange cloth 12 is sewn to the inner peripheral part of the lower mirror fabric 11. The other end of this flange cloth 12 is the spring unit 1
It is connected by a clip 13 to a coil spring 2 located around the periphery of the coil spring 2 . Further, the periphery of the lower mirror base 11 and the periphery of the exterior body 6 are sewn together by a bead 14 around the lower end of the spring unit 1. Therefore, the exterior body 6 has a lower mirror area 11.
The spring unit 1 is connected to the spring unit 1 through the spring unit 1, and is prevented from shifting.

According to the mattress having such a structure, the peripheral portion of the exterior body 6 provided on the upper surface side of the spring unit 1 is bent to cover the outer peripheral surface of the spring unit 1 as well. Therefore, the pattern of the outer cloth 9 of the outer case 6 is continuous on the upper surface side and the outer peripheral surface of the spring unit 1, so that the appearance is good. Further, the lower mirror base 11 is connected to the spring unit 1 by a flange cloth 12 to prevent the exterior body 6 from shifting. In other words,
Since the seams of the flange cloth 12 do not appear on the exterior body 6 on the upper surface side of the spring unit 1, the appearance can also be improved. Further, the peripheral edge of the exterior body 6 and the peripheral edge of the lower mirror base 11 are sewn together at the bead 14 on the lower surface side of the spring unit 1. Since the beaded edge 14 of the stitched portion located on the lower surface side of the spring unit 1 is rarely rubbed by the user, the suture thread of the beaded edge 14 is unlikely to fray over a long period of time.

In addition, as shown in FIG. 2, this invention makes the inner cloth 5a sufficiently larger than that of the above-mentioned embodiment.
The peripheral portion thereof may be bent to cover the outer peripheral surface of the spring unit 1, and the peripheral edge may be sewn together with the peripheral edges of the exterior body 6 and the lower mirror base 11 at the bead 14.

[Effect of idea]

As described above, according to this invention, the lower surface side of the spring unit is covered with a lower surface, the upper surface side and the outer peripheral surface are covered with an exterior body with the peripheral parts bent,
The peripheral edges of this exterior body and the lower mirror pad are sewn together on the lower surface side of the spring unit, and the lower mirror pad is connected to the spring unit by a flange cloth. Therefore, the pattern on the upper surface of the spring unit and the outer peripheral surface of the spring unit is continuous due to the outer body whose peripheral portion is bent, resulting in a good appearance, and the seam of the flange cloth does not appear on the upper surface of the spring unit as in the conventional case. Therefore, this also improves the appearance. Furthermore, since the seamed portion between the exterior body and the lower base material is located on the lower surface side of the spring unit, it has the advantage that it is less likely to be rubbed by the user and will not fray prematurely.
