DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the fixing of a filling material to a spring unit.

[0002]

2. Description of the Related Art In general, a spring mattress has a structure in which a number of coil springs are connected on a rectangular flat plate, and a felt-shaped spring receiving member made of coconut fiber or the like is attached to the upper and lower surfaces of the spring unit. A filling layer made of urethane foam or the like is laminated. This laminate is covered with an exterior body formed by a mirror portion and a gore portion.

[0003] In the mattress constructed as described above, in order to prevent the padding layer from shifting with respect to the spring unit, the mattress is connected and fixed to the spring unit by a number of fog rings and clips.

In order to prevent the outer body from being displaced with respect to the spring unit, a flange cloth having one end connected and fixed to the inner peripheral surface of the mirror is provided, and the other end of the flange cloth is padded around the spring unit. Like the layer, it was connected and fixed by a clip.

[0005] In the mattress constructed as described above, the displacement from the spring unit can be prevented by fixing the padding layer to the spring unit by fog rings or clips, and the outer body can also be displaced by fixing the flange cloth with clips or the like. Has been prevented.

However, the work of connecting and fixing the spring unit to the spring unit with a large number of fixing devices such as fog rings and clips and the work of connecting and fixing the flange cloth to the spring unit require a great deal of man-hours, resulting in a decrease in productivity. Was.

For this purpose, Japanese Unexamined Patent Publication (Kokai) No. 6-237841 proposes a method of fixing a filling layer to a spring unit by heating and shrinking a heat-shrinkable synthetic resin.

In the case of the fixing method described above, the man-hour for fixing the filling layer to the spring unit is certainly reduced, but a heating furnace is required for heating the entire mattress with hot air for fixing, and a heating temperature of 50 ° C. is required. Even when heated at ~ 130 ° C., it takes time to shrink, so that the heat-shrinkable synthetic resin shrinks and the filling layer does not shift from the spring unit until the filling layer is completely fixed to the spring unit. It was necessary to perform temporary fixing, and the process and contraction time of the temporary fixing work were eventually required, which did not lead to an improvement in productivity.

Further, in order to shorten the shrinkage time, it is necessary to heat at a high temperature (100 ° C. or higher), and the heat impairs the cushioning property of the filling layer. When heating is performed at a high temperature, high-temperature hot air is sent from the nozzle, which has been accompanied by danger.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks, to allow the filling layer to be fixed to the spring unit in a short time and safely, and to facilitate the centering operation.

[0011]

According to the present invention, a spring receiving member (3) is laid on upper and lower surfaces of a spring unit (2) in which a large number of coil springs (1) are connected in a plate shape.
A padding layer (4) is additionally provided thereon, and the whole is covered with an exterior body (7) formed of a mirror part (5) and a gore part (6). Part (8) is wrapped around the frame (9) on the outer periphery of the spring unit (2),
The space between the upper and lower portions is adhesively fixed, and the periphery of the plane between the lamination of the filling layer (4) and the spring receiving material (3) and a plurality of arbitrary positions in the plane are linearly adhered and fixed. A mattress characterized in that a plane portion between the mirror portions (5) is diagonally bonded to a flat portion.

[0012]

[Function] Spring unit (2) and spring receiving material (3)
Are bonded and fixed at the peripheral portion, and the spring receiving material (3) and the filling layer (4) and the filling layer (4) and the mirror portion (5) are bonded and fixed between the laminated layers. (3) The filling layer (4) and the mirror part (5) do not shift or move from the spring unit (2), and the work of centering the flange cloth on the spring unit by a clip or the like as in the related art is required. Since it is no longer necessary, no mistakes such as clipping occur, and it can be fixed easily, quickly and securely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. As shown in FIG.
・ Coil springs (1) arranged vertically and horizontally
··························································································································································· 枠 · To form a spring unit (2).

The peripheral portion (8) of the spring receiving member (3) having a slightly larger entanglement than the plane of the spring unit (2) is wound around the frame (9) of the spring unit (2), and the hot melt (11) is formed. The adhesive is fixed by heating the hot melt (11) to about 50 ° C. Further, the adhesive fixation is not limited to hot melt, but may be fixation with another adhesive.

As shown in FIG. 2, the upper and lower surfaces of the spring unit (2) are made of a compressed felt made of coconut fiber as a spring receiving material (3), on which cotton or urethane foam or the like is further placed. Filling layer (4) and outer material (1
A cushioning material (14) such as cotton or urethane foam is put between the lining (13) and the lining (13), and a mirror part (5) integrally quilted is sequentially laminated. Partially adhered by the melt (11). The gore part (6) consists of the mirror part (5) and the tape (1).
It is sewn by 5).

Next, as shown in FIG. 3, the spring receiving member (3)
A padding layer (4) having a size approximately equal to the size of the flat portion of the spring receiving member (3) is laminated and partially adhered and fixed. In the bonding and fixing portion, a peripheral portion (8) and a plurality of arbitrary portions in a plane are linearly bonded by a hot melt (11).

As shown in FIG. 4, the filler layer (4) and the mirror part (5) are also bonded and fixed, and the bonding part is formed by two lines of hot melt (11) diagonally in a plane part. ).

The diagonally fixed adhesive is used when the mirror (5) and the gore (6) are sewn with the tape (15) when the entire surface between the layers is adhesively fixed. Department (5)
When the tape (15) is sewn with the tape (15), the tape (15) becomes linear when the tape (15) is sewn, because the tape (15) has a wavy line and loses aesthetic appearance. It is intended to enable sewing while adjusting so as to be.

[0018]

According to the present invention, the spring unit (2) and the spring receiving member (3) are bonded and fixed only at their peripheral edges, and the padding layer (4) laminated on the spring receiving member (3). ) And the mirror part (5) are also securely fixed by the minimum necessary linear adhesive fixing. Therefore, as in the case of the conventional spring mattress, the spring receiving material (3) and the padding are used. In order to fix the layer (4) and the mirror part (5) to the spring unit (2), there is no need to connect with a clip or the like, and the clip or the like is not mistakenly hit, easily and reliably in a short time. Can be fixed to the spring unit (2)

Further, since a heat-shrinkable synthetic resin is not used for fixing the filling layer disclosed in JP-A-6-237841, there is no need to apply high-temperature (about 100 ° C.) heat for heat shrinkage. There is no need to worry about changes in physical properties due to heat of the filling material and the like, and the operation can be performed safely without danger.
