DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress device formed by laminating a padding on a spring unit and covering the laminated body with an outer package.

[0002]

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.

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.

The spring unit is formed in a rectangular shape by connecting a large number of coil springs with helical wires, and frame lines are connected to the upper and lower peripheral edges by clips. Spring units are typically quite large, about 2 m in length and about 1 m in width. Therefore, if it is attempted to handle the same size at the time of disposal, the handling may not be easy. In addition, if it is so large, it may not be possible to collect it at a normal collection route at the time of disposal, and it may be necessary to collect it as a bulky waste at a special route.

[0008]

As described above, in the conventional mattress device, the padding is connected to the spring unit with a large number of clips, and the outer body is also connected to the spring unit with the clip via the flange cloth. The assembling work may take a lot of time, and it may be difficult to disassemble each material at the time of disposal. In addition, the spring unit is rather large and may not be easy to handle at the time of disposal.

The present invention has been made based on the above circumstances, and an object of the present invention is to connect a padding and an outer package to a spring unit without using a large number of clips. An object of the present invention is to provide a mattress device in which a body can be easily disassembled and a spring unit itself can be disassembled into a small size.

[0010]

According to the present invention, a spring unit having an upper surface and a lower surface and divided at an intermediate portion in a longitudinal direction, and a divided portion of the spring unit are removably connected. An exterior body comprising: a first connecting means; a padding laminated on at least an upper surface of the spring unit; a mirror portion covering at least an upper surface of a laminate of the padding and the spring unit; and a gusset covering an outer peripheral surface. One end in the width direction is formed of a heat-shrinkable synthetic resin, and one end in the width direction is connected to the inner surface of the mirror portion and is provided at the outer periphery of the padding. And a second connecting means for engaging the second connecting means.

[0011]

According to the above construction, the spring unit is the first type.
Can be disassembled by the connecting member, and can be disassembled into small pieces. Also, the second connecting member, one end of which is connected to the mirror portion of the exterior body, is contracted by heating, and the other end is spring-loaded. By engaging the outer peripheral portion of the unit, these connecting operations can be performed easily and quickly. Further, the padding and the outer package connected to the spring unit by the second connecting member are made of synthetic resin. Simply by cutting and removing the second connecting member, it can be separated from the spring unit.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of the present invention. The mattress device shown in FIG.
Having. 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 the upper and lower peripheral edges of the spring unit 1 by clips 10 as shown in FIG. In addition, the spring unit 1 is configured to be disassembled by first connecting means described later.

On the upper and lower surfaces of the spring unit 1, paddings 6 formed in a rectangular shape slightly larger than the upper and lower surfaces of the spring unit 1 are stacked and 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.

On the linings 8b, 9b of the mirrors 8, 9,
One end 13a in the width direction of a tape-shaped connecting member 13 as a second connecting means, which is made of a relatively soft heat-shrinkable synthetic resin over the entire periphery and is bent in an L-shaped cross section, is formed. They are connected by means such as bonding or sewing, in this embodiment by sewing. As the heat-shrinkable resin forming the connecting member 13, vinyl chloride resin, EPT, PETP, cross-linked polyethylene, silicone rubber, and the like are used. These resins are formed by heating and the molded product is reheated. Utilizes the phenomenon of trying to return to the original form.

In a state where 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 upper surface of the peripheral portion of the protective member 5 (spring unit 1) as shown in FIG. And the other end 13b covers the outer peripheral surface of the protective material 5.
When the connection member 13 is heated and contracted in this state,
Since the other end 13b covering the outer peripheral surface of the protection member 5 is bent inward, the other end 13b is brought into pressure contact with the upper and lower peripheral edges of the spring unit 1 as shown in FIG.

After the connecting member 13 is thermally contracted, the upper and lower ends of the gusset 11 of the exterior body 7 are formed around the mirrors 8 and 9 by the tape 12 as described above. Sewn on.

The spring unit 1 is configured as shown in FIG. That is, the helical wire 3 connecting the upper and lower end surfaces of the coil spring is provided along the longitudinal direction of the spring unit 1. The middle part of the helical wire 3 in the longitudinal direction is divided at two points, and both ends of the divided point are inserted into a first tube 21 made of a heat-shrinkable resin as shown in FIG. Then, the first tube 21 is connected by heating to shrink the first tube 21.

The part of the frame line 4 corresponding to the part of the helical line 3 is also divided. That is, frame 4
In FIG. 4B, two halfway portions along the side of the spring unit 1 along the longitudinal direction are divided.
As shown in FIG. 2, the second tube 22 is inserted through a second tube 22 made of a heat-shrinkable resin.
Are thermally contracted.

Since the first tube 21 and the second tube 22 are resin tubes, they can be easily cut. Therefore, when the first tube 21 and the second tube 22 are cut, the spring unit 1 can be divided into three unit portions 1a, 1b, and 1c. That is, the first tube 21 and the second tube 22 constitute the above-mentioned first connecting means.

FIGS. 5A to 5D show the steps of manufacturing the mattress device having the above-mentioned structure. FIG. 5A shows a first step. In this first step, the padding 6 is laminated on the upper and lower surfaces of the spring unit 1 via the protective material 5. The spring unit 1 is preliminarily disassembled by a first tube 21 and a second tube 22.

FIG. 5B shows a second step which is performed in parallel with the first step in time. In the second step, the inner surfaces of the linings 8b and 9b of the upper mirror part 8 and the lower mirror part 9 are formed. One end in the width direction of the connecting member 13 is fixed to the peripheral portion by an adhesive or sewing.

In a third step shown in FIG. 5 (c), the upper mirror 8 and the lower mirror 9 to which the connecting member 13 is fixed are stacked on the padding 6 stacked on the upper and lower surfaces of the spring unit 1. Is done.

The spring unit 1 on which the mirror portions 8 and 9 are stacked in the third step is carried into the hot air heating furnace 24 by the conveyor 23 in the fourth step shown in FIG. In the air heating furnace 24, the air is heated to 50 to 130 ° C. by hot air. Therefore, each connecting member 13 provided on the inner surface of each of the mirror parts 8 and 9 thermally contracts, and the other end 13 in the width direction thereof
a engages the upper and lower peripheral edges of the spring unit 1.
As a result, the mirrors 8, 9 to which the one end 13a of the connecting member 13 is connected and fixed are fixed to the spring unit 1, and are provided between the mirrors 8, 9 and the upper and lower surfaces of the spring unit 1. Each padding 6 is also fixed to the spring unit 1. That is, the laminate of the spring unit 1, the padding 6, and the mirror portions 8, 9 is integrally connected.

The first tube 21 and the second tube 22 may be thermally contracted together with the connecting member 13 without being thermally contracted in advance. In the fifth step, the outer peripheral surface of the spring unit 1 of the laminate unloaded from the heating furnace 24 is covered with the gusset 11, and the upper and lower ends of the gusset 11 are then covered with the upper mirror 8 and the lower mirror. By suturing the peripheral portion of the portion 9 with the tape 12, the mattress device shown in FIG. 1 is manufactured.

According to the mattress device manufactured as described above, the paddings 6 and the mirror portions 8 and 9 stacked on the upper and lower surfaces of the spring unit 1 are connected to the connecting members 13 provided on the mirror portions 8 and 9. It is connected to the spring unit 1 by heat-shrinking and engaging the other end 13b with the upper and lower peripheral edges of the spring unit 1.

That is, the padding 6 and the mirror parts 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 connection member 13 is thermally contracted. It can be connected and fixed to the spring unit 1. Therefore, the work of connecting and fixing the filling 6 and the mirror parts 8 and 9 to the spring unit 1 can be performed easily and quickly, and without manual work.
Can be automated.

On the other hand, if the spring unit 1 is to be separated from the padding 6 and the exterior body 7 and the spring unit 1 is to be cut off in order to discard the mattress device having the above-mentioned structure, the gusset 11 must be mirrored by mirrors 8 and 9. Tape 12 connected to
After the gusset 11 is removed, a cut is made in the other end portion 13b of the connecting member 13 engaged with the spring unit 1 along the width direction with a cutter or the like, and the connecting member 13 is cut from the cut portion. By tearing the other end 13b of the spring member 1 in the circumferential direction of the spring unit 1, the engagement between the connecting member 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 outer package 7 can be separated from the spring unit 1 by a relatively easy operation of tearing the connecting member 13 formed of a tape-shaped synthetic resin.

After the padding 6 and the outer package 7 are separated from the spring unit 1, the first tube 21 and the second tube 21 which connect the helical line 3 and the frame 4 of the spring unit 1 are connected. Cut off the stub 22. Thereby, the spring unit 1 can be divided into three,
Handling of the spooling unit 1 at the time of disposal is facilitated.

In the first embodiment, the padding 6 laminated on the upper and lower surfaces of the spring unit 1 via the protective material 5 may be partially bonded together with the protective material 5 by hot melt. Good. As the hot melt, a material that cures at a temperature lower than the temperature at which the connecting member 13 shrinks, for example, about 50 ° C. is used.

As described above, if the filling 6 is bonded to the spring unit 1 by hot melt, the hot melt is cured and the filling 6 is fixed to the spring unit 1 before the connecting member 13 thermally contracts. for that reason,
Even if the thermal contraction of the connecting member 13 does not progress uniformly in the circumferential direction of the spring unit 1, the padding 6 is prevented from moving on the spring unit 1. In addition, since the adhesive 6 is partially fixed by hot melt, the filler 6 can be easily separated from the spring unit 1 during disassembly.

The end surfaces 34a and 34b are arranged at a predetermined pitch with respect to the longitudinal direction of the spring unit 32, and one end along the longitudinal direction of the upper end surface 34a and the same end of the lower end surface 34b are connected to the upper and lower ends of the coil portion 34c. Thus, the continuous spring 33 is formed.

The spring unit 32 has a plurality of middle portions in the longitudinal direction, and in this embodiment, two middle portions of the wire forming the lower end surface portion 34b are cut off.
That is, the continuous spring 33 is divided into three parts, whereby the spring unit 32 is divided into three unit parts 32a to 32c as shown in FIG.

The plurality of continuous springs 33 arranged side by side
The Z-shaped contact portions of the adjacent upper end surface portion 34a and lower end surface portion 34b are connected by the helical wire 3 respectively. A frame 4 for reinforcing the spring unit 32 at the upper and lower peripheral edges thereof is provided with a clip 3.

FIGS. 10 to 12 show a third embodiment of the present invention. This embodiment is the same as the first embodiment in that the spring units 41 are configured by arranging the coil springs 2 in a matrix, but the upper and lower end surfaces of the arranged coil springs 2 are Spring unit 4
1 in that they are connected by a helical wire 3 provided along the width direction of the helical wire.

The upper and lower end surfaces of the coil spring 2 are joined to two places in the middle of the spring unit 41 in the longitudinal direction by a connecting member 42 formed of a heat-shrinkable sheet instead of the helical wire 3.

As shown in FIG. 12, the connecting member 42 is formed at the same pitch as the coil spring 2 in which a wide connecting portion 42b is juxtaposed on an elongated strip portion 42a. After the connecting member 42 is provided along the width direction of the spring unit 41, the upper end surface or the lower end surface of the pair of adjacent coil springs 2 is held by the connecting portion 42b, and the connecting member 42 is heated in that state. Then, the connecting portion 42b contracts as shown in FIG. 11 to join the pair of end surfaces.
