2. Description of the Related Art In general, a mattress device has a spring unit formed by connecting a large number of coil springs in a matrix, and a padding such as synthetic cotton or urethane foam is laminated on the spring unit. . This laminate is covered with an exterior body formed of a mirror portion and a town portion.

In the mattress device having such a configuration, the padding is connected and fixed to the spring unit with a large number of clips in order to prevent the padding from moving relative to the spring unit. Further, in order to prevent the exterior body from moving relative to the spring unit, one end is connected and fixed to the inner surface of the mirror unit to provide a flange cloth, and the other end of the flange cloth is provided around the spring unit. Like the padding, the clip is connected and fixed.

According to such a configuration, the padding is prevented from moving by the clip, and the outer body is prevented from moving by the flange cloth. However, since the operation of connecting the padding to the spring unit with a large number of clips requires a great deal of time and labor, the productivity may be reduced.In addition, the operation of connecting the flange cloth by the spring unit may be required. It can take a lot of time.

[0005] On the other hand, when the mattress device is damaged due to long-term use and must be discarded, recently, the waste is not collected unless it is discarded for each type of material. In many areas, collection systems are used. When the mattress device is discarded in an area where the sorting and collection is being performed, the spring unit, which is a metal part, and the padding and the outer casing made of synthetic fiber or the like must be discarded separately.

In this case, if the padding is connected to the spring unit by a large number of clips, it is not easy to remove the padding from the spring unit, and similarly, it is not easy to remove the outer package from the spring unit. Therefore, the disassembly work at the time of disposal may take a lot of trouble.

[0007] In view of this, the present applicant has proposed a mattress device disclosed in Japanese Patent Application No. 5-26968 in order to make it possible to easily remove the exterior body from the spring unit. In this prior art, a flange cloth provided on a mirror base is formed of a heat-shrinkable synthetic resin, and after the mirror base is laminated via a padding in a springing unit, the flange cloth is heated. Thereby, since the flange cloth contracts and engages with the periphery of the spring unit,
The padding prevents the padding from shifting on the spring unit.

However, when the flange cloth is made of a heat-shrinkable synthetic resin, the flange cloth must be heated in order to shrink. In order to heat the flange cloth, it is necessary to blow hot air or to pass the assembled mattress device through a heating furnace, so that the work is not only troublesome but also requires equipment for heating. There were things like becoming.

[0009]

As described above, in the conventional mattress device, the flange cloth is formed of a heat-shrinkable synthetic resin, and by heating the flange cloth, the padding is prevented from shifting and moving on the spring unit. It was meant to be held through a mirror.

[0010] For this reason, it is not easy to heat and shrink the flange cloth, which may lead to a decrease in productivity. In addition, heating equipment may be required, leading to an increase in cost. there were.

The mattress device shown in FIGS. 1 and 2 has a spring unit 1. The spring unit 1 is formed by arranging a large number of coil springs 2 in a matrix and connecting upper and lower end surfaces of adjacent coil springs 2 with a helical wire 3. A frame line 4 is connected to upper and lower peripheral edges of the spring unit 1 by clips (not shown).

On the upper and lower surfaces of the spring unit 1, a padding 6 formed in a rectangular shape slightly larger than the upper and lower surfaces of the spring unit 1 is stacked via a sheet-like protective material 5 such as felt. Is placed. The filling 6 is formed by compressing synthetic fiber into a layer having a predetermined thickness.

The laminate of the spring unit 1 and the padding 6 is covered with an outer package 7. The exterior body 7 includes an upper mirror section 8 and a lower mirror section 9 which are respectively laminated on the upper and lower surfaces of the spring unit 1, and a town section 11 which covers the outer peripheral surface. These mirror parts 8 and 9 and the town part 11 are composed of outer materials 8a, 9a and 11a and linings 8b, 9b and 11b.
Between the sheet-like urethane forms 8c, 9c, 11
c, and the three are integrally quilted. The upper and lower ends of the gusset 11 are integrally sewn to the periphery of the upper mirror 8 and the lower mirror 9 by a tape 12.

As shown in FIGS. 3 and 4, a tape-shaped flange cloth having a predetermined width as a connecting member is provided on the entire periphery of the linings 8b and 9b of the mirror portions 8 and 9 as shown in FIGS. 13 are connected to each other at one end 13a in the width direction by means such as suturing. The flange cloth 13 is divided at a pair of opposing corners.

The other end 13b in the width direction of the flange cloth 13
Has an insertion portion 14 formed by folding back and suturing the end portion thereof.
5 is inserted. Both ends of each of the string upper members 15 are led out from a pair of cut portions.

In a state in which the mirror portions 8 and 9 are stacked on the protective member 5, one end 13a in the width direction of the connecting member 13 is connected to the peripheral portion of the upper surface of the protective member 5 (as shown in FIG. 2). The other end 13b covers the outer peripheral surface of the protective member 5, and the insertion portion 14 is thicker than the upper and lower surfaces of the spring unit 1 in this state. Spring unit 1 that is inward in the direction
Is located on the outer peripheral surface. That is, the length of the other end portion 13b of the flange cloth 13 is set to be longer than the thickness of the padding 6.

The assembling of the mattress device having the above structure is as follows.
When the padding 6 is laminated on the upper and lower surfaces of the spring unit 1 via the protective material 5, the upper mirror surface 8 and the lower mirror surface 9 are laminated on the filler 6.

Then, the other ends 13b of the flange cloth 13 are contracted by pulling the both ends of the pair of string members 15 derived from the two cut portions of the flange cloth 13, and in this state, these string members 15 Both ends are joined so that the contracted state of the flange cloth 13 does not return.

Accordingly, the other end 1 of the flange cloth 13
As shown in FIG. 1, 3b is deformed while wrapping around the periphery of the padding 6 from the state of FIG. 2 and engages with the peripheral portions of the upper and lower surfaces of the spring unit 1, so that each mirror unit 8, 9 is attached to the spring unit 1. Be combined.

When the mirrors 8 and 9 are connected to the spring unit 1, the padding 6 is held on the upper and lower surfaces of the spring unit 1 by these mirrors 8 and 9 and is prevented from shifting. .

When the mirrors 8 and 9 are connected to the spring unit 1 in this manner, the upper and lower ends of the gusset 11 are joined to the peripheral edges of the mirrors 8 and 9 and the joined portions are joined together. By covering with tape 12 and suturing and joining these overlapping portions, the mattress device is assembled.

According to the mattress device having such a configuration, the paddings 6 and the mirror portions 8 and 9 stacked on the upper and lower surfaces of the spring unit 1 are inserted through the flange cloth 13 provided on the mirror portions 8 and 9. String member 15 passed through section 14
By tightening the other end, the other end of the flange cloth 13 is contracted to be engaged with the upper and lower peripheral edges of the spring unit 1.
The spring unit 1 is integrally connected.

That is, the padding 6 and the mirror portions 8 and 9 stacked on the spring unit 1 are not connected to the spring unit 1 by using a large number of clips as in the prior art, and only the string-like member 15 is tightened. Spring unit 1
Can be held and fixed. Therefore, the filling 6
The operation of connecting and fixing the mirror units 8 and 9 to the spring unit 1 can be performed easily and quickly.

On the other hand, when separating the spring unit 1 from the padding 6 and the exterior body 7 in order to dispose of the mattress device having the above structure, the tape 12 having the gusset 11 connected to the mirrors 8 and 9 should be used. After removing the gusset 11 and removing the gusset 11, the string member 15 is loosened to release the contracted state of the other end of the flange cloth 13, so that the connection between the flange cloth 13 and the spring unit 1 can be released.

As a result, the padding 5 and the mirror parts 8, 9 can be separated from the spring unit 1. That is, at the time of disposal, the padding 6 and the exterior body 7 are quickly separated from the spring unit 1 by a relatively easy operation of releasing the connection of the pair of string members 15 and extending the contracted flange cloth 13. Can be.

FIG. 5 shows a second embodiment of the present invention. In this embodiment, the flange cloth 13 provided on the inner surface of each of the mirror portions 8 and 9 is not divided at two places but is divided at only one place.

Therefore, one string-like member 15 is inserted into the insertion portion 14 formed at the other end of the flange cloth 13, and both ends thereof are led out from one cut portion. When the other end portion 13b is contracted, it is only necessary to tighten both end portions of one string-shaped member 15.

In the above-described embodiment, the case where the padding is provided on both the upper and lower surfaces of the spring unit has been described. Of course, it is possible.
