Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a mattress device in which a cushion body is attached to at least one of the upper and lower surfaces of a spring unit.

[Technical background of the invention and its problems]

Generally, a mattress device has a spring unit formed by connecting a large number of coil springs in a flat plate shape, and a cushion body is provided on at least one of the upper and lower surfaces of the spring unit. As this cushion body, one in which an elastic material such as urethane foam is interposed between the outer material and the lining material is often used. The periphery of the cushion body is sewn with edge tape to the gusset covering the outer peripheral surface of the spring unit, and the periphery of the lining is a flange with one end sewn to the lining and the other end connected to the coil spring. It is fixed to the spring unit by a cloth.

By the way, in such a cushion body, the outer material, the lining material, and the elastic material are integrally quilted in order to improve the appearance and prevent the elastic material from shifting. One of the important requirements for quilting is that the lines be deep and clear. However, in the above-mentioned pine stress device,
When providing a quilted cushion body,
The periphery of the cushion body is sewn to the gusset,
When fixing the lining to the spring unit with the flange cloth, it is necessary to apply a considerable amount of tension to the cushion body in order to ensure that the lining does not sag. This tension causes the outer material, lining material, and elastic material of the cushion body to stretch, which has the disadvantage that the quilting lines become shallow and unclear.

[Purpose of invention]

The object of this invention is to provide a mattress device which prevents the cushion body from stretching due to the tension applied to the cushion body and making the quilting lines shallow and unclear when the cushion body is installed in a spring unit.

[Summary of the idea]

In this invention, a non-stretch reinforcing fabric is stretched on the back side of a quilted cushion body, the peripheral portion of which is connected to a spring unit by a flange fabric, and the cushion body is bonded to this reinforcing fabric. This is a matsutress device in which the cushion body is prevented from stretching with the reinforcing fabric.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. Figure 1 shows bed 1, and this bed 1
has a base body 2. A pinerest device 3 is placed on the upper surface of this base 2. This mattress device 3 has a spring unit 4 as shown in FIG.
It is equipped with This spring unit 4 is formed by connecting a large number of coil springs 5 in a flat plate shape with helical wires 6a. Frame lines 6 are provided on the peripheries of the upper and lower surfaces of the spring unit 4, respectively. Further, upper cushion bodies 8 are successively placed on the upper and lower surfaces of the spring unit 4 with a lower cushion body 7 interposed therebetween. The lower cushion body 7 is formed of urethane foam or the like into a rectangular shape larger than the spring unit 1. In addition, the upper cushion body 8 has an outer material 9.
An elastic material 11 made of a sheet-like urethane foam 11a laminated with cotton 11b is interposed between the lining 10 and the lining 10, and these three are sewn together by quilting 12. On the back side of the upper cushion body 8, that is, between the lining 10 and the lower cushion body 7, there is interposed a non-stretch reinforcing fabric 13, such as plain weave fabric or canvas, which hardly stretches even when tension is applied. has been done. One end of a flange cloth 14 is sewn to the periphery of the reinforcing cloth 13, and the other end of the flange cloth 14 wraps around the periphery of the lower cushion body 7 to form a coil spring 5 located at the periphery of the spring unit 4. It is connected with a clip 15. In other words,
The reinforcing fabric 13 is stretched over the lower cushion body 7 with a predetermined tension by means of a flange fabric 14. The peripheral edges of the reinforcing fabric 13 and the upper cushion body 8 are integrally sewn together by a seam 16. Furthermore, a gusset 17 is provided on the outer peripheral surface of the spring unit 4. The peripheral edges of the reinforcing fabric 13 and the upper cushion body 8 are sewn to the upper and lower ends of the gusset 17 with edge tapes 18.

According to the pine stress device 3 having such a structure,
When the upper cushion body 8 is superimposed on the lower cushion body 7 and the peripheral edge of the upper cushion body 8 is sewn to the upper and lower ends of the gusset 17 with the edge tape 18, a large tension is applied to the upper cushion body 8. It will be done. However, the peripheral edge of the upper cushion body 8 is sewn to the gusset 16 together with the peripheral edge of the reinforcing fabric 13. Therefore, when tensioning the upper cushion body 8, the tension is applied to the upper cushion body 8 and the reinforcing fabric 13, so the non-stretchable reinforcing fabric 13 prevents the upper cushion body 8 from stretching. be done. Therefore, the shape of the quilting 12 formed on the upper cushion body 8 does not collapse. In other words, quilting 1
The line 2 does not become shallow and unclear.

[Effect of idea]

As described above, this invention provides an upper cushion in which a lower cushion body is provided on at least one of the upper and lower surfaces of the spring unit, an elastic material is provided between the outer material and the lining material, and these three are integrally quilted. The bodies are sequentially polymerized, a non-stretch reinforcing fabric bonded to the upper cushion body is stretched on the back side of the upper cushion body, and the lower cushion body is wrapped around the flange fabric provided on the reinforcing fabric to form a spring. In addition to being connected to the spring unit, the upper cushion body, the reinforcing fabric, and the gusset provided on the outer peripheral surface of the spring unit are sewn together. Therefore, when the upper cushion body is stretched over the spring unit, the tension is applied to the upper cushion body and the reinforcing fabric, and the reinforcing fabric prevents the upper cushion body from stretching, and the tension applied to the upper cushion body is The quilting will not lose its shape and will not spoil its appearance. Furthermore, even if the upper cushion body is stretched with some slack, the reinforcing fabric is stretched without any slack, so the gusset will not sag, and the overall appearance of the pine restraint device will not be damaged. It has the following advantages.
