Description

The present invention relates to a cushion body cover in which a cushion body is housed, and a cushion body with a cover, a mattress, and a method for manufacturing the mattress.

Conventionally, a cushion body (a cushion body that supports an upper user) used for a mattress, a cushion for a sofa, or the like has been widely used. As such a cushion body, for example, as disclosed in Patent Document 1 and Patent Document 2, a filament three-dimensional bond (three-dimensional network shape) obtained by three-dimensionally fusion-bonding a filament made of a thermoplastic resin. Some are formed by structures).

According to Patent Document 1, after extruding a molten polyethylene resin vertically downward from a plurality of horizontally arranged nozzles, a molten filament having a diameter of about 1 mm is dropped into cooling water and melted by the buoyancy of water. It is disclosed that by forming a loop of filaments and at the same time forming a three-dimensional fusion bond between a plurality of molten filaments, an extremely airy filament three-dimensional bond having a void ratio of more than 90% can be produced. There is.

Further, when forming a mattress using a filament three-dimensional bond, for example, a cushion body of the filament three-dimensional bond formed in a plate shape (usually a rectangular plate shape) is prepared, and the cushion body is covered with the mattress. A mattress is formed by storing it in the (bag body). When forming one mattress by using a plurality of small cushion bodies, each cushion body is sequentially stored in the mattress cover.

The above-mentioned filament three-dimensional bond is formed by entwining filaments with each other, and a non-smooth surface portion (for example, a portion of the surface where the tip of the filament protrudes) may occur. Therefore, in the step of storing the cushion body of the filament three-dimensional coupling body in the bag body such as a mattress cover, the non-smooth surface portion may be caught in the bag body, which may hinder the smooth execution of the process.

If the cushion body is stored in the inner cover in advance and the cushion body with the inner cover is stored in the bag body, the cushion body and the bag body do not directly rub against each other, and the storage process in the bag body can be performed. It will be possible to proceed smoothly. However, in this case, since the inner cover covers the surface of the cushion body, there arises a problem that the original air permeability of the cushion body is impaired accordingly. The above can also be a problem when storing other types of cushion bodies having a non-smooth surface portion in the bag body.

In view of the above-mentioned problems, the present invention makes it possible to easily store the cushion body having a non-smooth surface portion in the bag body, but to prevent the air permeability of the cushion body from being impaired as much as possible. The purpose is to provide a cover.

According to this configuration, it is possible to easily store the cushion body having a non-smooth surface portion in the bag body, but to prevent the air permeability of the cushion body from being impaired as much as possible.

More specifically, as the above configuration, an opening for exposing a part of the cushion body is provided in each of the upper surface portion facing the upper surface of the cushion body and the lower surface portion facing the lower surface of the cushion body. May be.

More specifically, the upper surface portion may cover the entire outer edge of the upper surface of the cushion body, and the lower surface portion may cover the entire outer edge of the lower surface of the cushion body. According to this configuration, it is possible to suppress an unintended deviation of the cushion body from the cushion body cover and to cover the vicinity of the corners of the cushion body to smooth the surface.

Further, in the cushion body cover having the configuration in which the cushion body formed by the filament three-dimensional coupling is accommodated, the size of at least one of the upper surface portion and the lower surface portion is determined through the opening. The cushion body may be configured so that it can be detachably accommodated. According to this configuration, the work of detachably accommodating the cushion body becomes easy.

Further, in a cushion body cover having a structure having a side surface portion covering the entire peripheral side surface of the cushion body and the upper surface portion and the lower surface portion being connected to the side surface portion, the upper surface portion and the lower surface portion of the cushion body cover. The size of both of the openings may be set so that the cushion body can be detachably accommodated through the openings.

Further, the cushion body with a cover according to the present invention has a structure including a cushion body cover having the above configuration and the cushion body housed in the cushion body cover. Further, the mattress according to the present invention has a configuration including a plurality of cushion bodies with covers having the above configuration and a bag-shaped mattress cover in which the plurality of cushion bodies with covers are housed.

Further, in the method for manufacturing a mattress according to the present invention, in the cushion body cover having the above configuration, a first step of accommodating the cushion body and a plurality of cushion bodies with a cover formed by the first step are each put into one bag. The method includes a second step of storing the mattress cover in the shape of a mattress.

It is a schematic perspective view of the cushion body cover 20 which concerns on this embodiment, and the cushion body 10 accommodated therein. It is a schematic perspective view of the cushion body 100 with a cover which concerns on this embodiment. It is a schematic perspective view from another viewpoint of the cushion body 100 with a cover. It is a schematic perspective view of the mattress 110 which concerns on this embodiment. It is explanatory drawing about the catching in a storage process.

An example of an embodiment of the present invention will be described below with reference to each drawing. The vertical, horizontal, and front-back directions in the following description are as shown in FIG. 1 and the like. The vertical direction here is merely defined for convenience so as to coincide with the thickness direction of the cushion body.

FIG. 1 is a schematic perspective view of a cushion body cover 20 according to the present embodiment and a cushion body 10 housed therein. The cushion body 10 is a filament three-dimensional coupling body, and is formed in the shape of a rectangular parallelepiped plate having a thickness direction in the vertical direction. Since the vertical direction is the thickness direction, the upper surface and the lower surface of the cushion body 10 are sufficiently wider than the front, rear, left, and right side surfaces. Since the method for producing the filament three-dimensional conjugate is known as disclosed in, for example, Patent Document 1 and Patent Document 2, detailed description thereof will be omitted here.

The cushion body cover 20 is formed of a smooth sheet material made of, for example, resin or various fibers, and has an upper surface portion 21 corresponding to the upper surface and a lower surface corresponding to the lower surface according to the shape of the cushion body 10. It is formed so as to have a portion 22 and a side surface portion 23 corresponding to the front, rear, left and right side surfaces. The front, rear, left, and right outer edges of the upper surface portion 21 and the lower surface portion 22 are connected to the outer edges of the front, rear, left, and right side surface portions 23. That is, the cushion body cover 20 has a side surface portion 23 that covers the side surface of the entire circumference of the cushion body 10, and the upper surface portion 21 and the lower surface portion 22 are connected to the side surface portion 23.

More specifically, the outer edges of the upper surface portion 21 and the lower surface portion 22 of the cushion body cover 20 are formed to have substantially the same shape and dimensions as the outer edges of the upper and lower surfaces of the cushion body 10. The outer edges of the left and right side surface portions 23 of the cushion body cover 20 are formed to have substantially the same shape and dimensions as the outer edges of the left and right side surfaces of the cushion body 10, and the outer edges of the front and rear side surface portions 23 of the cushion body cover 20. Is formed to have substantially the same shape and dimensions as the outer edges of the front and rear surfaces of the cushion body 10.

Therefore, the cushion body 10 housed in the cushion body cover 20 is adapted to fit the inner surface of the cushion body cover 20. Further, in this state, the upper surface portion 21 faces the upper surface of the cushion body 10, and the lower surface portion 22 faces the lower surface of the cushion body 10.

Further, an upper opening 21a is formed on the upper surface 21 of the cushion body cover 20, and a lower opening 22a is formed on the lower surface 22 of the cushion body cover 20. The upper opening 21a is provided so as to open a region near the center of the upper surface portion 21, and exposes a region near the center on the upper surface of the accommodated cushion body 10. The lower opening 22a is provided so as to open a region near the center of the lower surface portion 22, and exposes a region near the center on the lower surface of the accommodated cushion body 10.

In the example of the present embodiment, the shapes and sizes of the upper and lower openings 21a and 22a are the same, and the outer edge shape of each opening 21a and 22a is substantially similar to the outer edge shape of the upper surface portion 21 or the lower surface portion 22. is there. Further, in the example of the present embodiment, the area of each of the upper and lower openings 21a and 22a is set to about 60 to 80% of the area of the upper surface portion 21 or the lower surface portion 22, and each opening 21a and 22a is set to the upper surface. It is arranged so that the center positions of the portion 21 or the lower surface portion 22 coincide with each other.

Therefore, in a state where the cushion body 10 is housed in the cushion body cover 20, the upper surface portion 21 covers only the vicinity of the entire outer edge of the upper surface of the cushion body 10, and the lower surface portion 22 covers only the vicinity of the entire outer edge of the lower surface of the cushion body 10. It will cover. Further, since the upper surface portion 21 and the lower surface portion 22 have large openings in this way, the cushion body 10 can be accommodated inside the cushion body cover 20 through the openings as shown by the broken line arrows in FIG. It is possible.

When the cushion body 10 is housed in this way, it can be easily housed by bending the cushion body 10 lightly or extending the cushion body cover 20 lightly. Further, in the present embodiment, the cushion body 10 can be detachably accommodated in both the upper surface portion 21 and the lower surface portion 22 through the opening, but only one of the upper surface portion 21 and the lower surface portion 22 can accommodate the cushion body 10. Such accommodation may be possible.

By accommodating the cushion body 10 inside the cushion body cover 20, a cushion body with a cover can be formed. FIG. 2 is a schematic perspective view of the cushion body 100 with a cover, and FIG. 3 is a schematic perspective view of the cushion body 100 with a cover from another viewpoint.

As shown in these figures, in the cushion body 100 with a cover, most of the upper surface and the lower surface of the cushion body 10 near the center are exposed, and the air permeability of the cushion body 10 is impaired in this exposed area. Absent. As described above, even if the cushion body cover 20 is accommodated, the excellent air permeability of the cushion body 10 which is a filament three-dimensional coupling is hardly impaired, and the cushion body 100 with a cover maintains excellent air permeability.

On the other hand, in the cushion body 100 with a cover, the cushion body cover 20 covers the entire front, rear, left and right side surface portions 23 of the cushion body 10, and the vicinity of the entire outer edges of the upper surface portion 21 and the lower surface portion 22. Unintentional deviation of the cushion body 10 from the cushion body cover 20 is suppressed as much as possible. Further, the surface of the cushion body 100 with a cover is in a smooth state at least in the portion covered by the cushion body cover 20.

The cushion body 100 with a cover can be suitably used as a cushion member for forming a mattress, for example. For example, as shown in FIG. 4, cushion members 100A to 100C are prepared as a plurality of (three in the example of FIG. 4) cushion bodies with covers, and these are stored in one bag-shaped mattress cover 30. The mattress 110 is formed.

More specifically, each of the cushion member 100A, the cushion member 100B, and the cushion member 100C is inside the mattress cover 30 in this order via a storage port 30a that can be opened and closed by a zipper provided on one side surface of the mattress cover 30. It is stored in. After completing the storage process for storing all the cushion members 100A to 100C, the mattress 110 is completed through the process of closing the zipper. As the mattress cover, for example, a series of zippers (zippers arranged in a "U" shape when viewed upward) are provided on the side surfaces in three directions in which they are connected, and the upper surface can be freely opened and closed by opening the zippers. Those may be adopted. In this case, each of the cushion member 100A, the cushion member 100B, and the cushion member 100C can be stored in the mattress cover from above with the upper surface open.

In such a method of manufacturing a mattress, a first step of accommodating the cushion body 10 in the cushion body cover 20 and a plurality of cushion bodies 100 with a cover formed by the first step are each covered with one bag-shaped mattress cover. It includes a second step of storing in 30 and.

Here, assuming that the non-smooth surface portion of the cushion member (for example, the portion of the surface where the tip of the filament protrudes) is caught by the cushion body cover 20 in the above storage step, the smooth progress of the storage step is hindered. There is a risk of being done. When the cushion member X is stored in the cushion body cover 20 in a slightly tilted state as illustrated in FIG. 5, such a catch is provided in the vicinity of the corner portion of the cushion member X (particularly, the corner portion indicated by the broken line arrow in this figure). It tends to occur in the vicinity of).

However, in the cushion member (cushion body 100 with a cover) according to the present embodiment, since the cushion body 10 is housed in the cushion body cover 20 having a smooth surface, the cushion member (cushion body 100 with a cover) is caught at least in the portion covered by the cushion body cover 20. Is suppressed. The cushion body cover 20 exposes the upper surface and the lower surface of the cushion body 10 near the center from the viewpoint of not impairing the air permeability, but covers the vicinity of the corners of the cushion body 10 almost completely. The effect of suppressing the catch is high. In this way, the cushion body cover 20 serves as an inner cover for facilitating the storage of the cushion body 10 in the mattress cover 30.

As described above, the cushion body cover 20 according to the present embodiment is a cushion body cover that accommodates a plate-shaped cushion body 10 having a thickness direction in the vertical direction so as to cover at least a side surface, and the accommodated cushion. A part of the upper surface and the lower surface of the body 10 is exposed. More specifically, the cushion body cover 20 has openings that expose a part of the cushion body 10 at each of the upper surface portion 21 facing the upper surface of the cushion body 10 and the lower surface portion 22 facing the lower surface of the cushion body 10. A part is provided. Therefore, it is possible to easily store the cushion body 10 having a non-smooth surface portion in the bag body, but to prevent the air permeability of the cushion body 10 from being impaired as much as possible.

Further, the upper surface portion 21 covers the entire outer edge of the upper surface of the cushion body 10, and the lower surface portion 22 covers the entire outer edge of the lower surface of the cushion body 10. Therefore, it is possible to suppress an unintended deviation of the cushion body 10 from the cushion body cover 20 and to cover the vicinity of the corner portion of the cushion body 10 to smooth the surface.

Further, in the cushion body cover 20 in which the cushion body 10 formed by the filament three-dimensional coupling is housed, the size of the upper opening 21a and the lower opening 22a is such that the cushion body 10 is attached and detached through the openings. It is set so that it can be accommodated freely. Therefore, the work of detachably accommodating the cushion body is easy.

When setting the size of the opening in this way, the characteristics such as the size and bendability of the cushion body 10 (filament three-dimensional coupling) and the characteristics such as the ease of expansion and contraction of the cushion body cover 20 are determined. It is preferable to consider. In particular, in the present embodiment, the cushion body 10 can be detachably accommodated in the cushion body cover 20 via either the upper opening 21a or the lower opening 22a, which is excellent in convenience.

The cushion body cover 20 of the present embodiment accommodates the cushion body 10 formed by the filament three-dimensional coupling, but the cushion body cover according to the present invention accommodates other types of cushion bodies. May be good. By preliminarily accommodating various cushion bodies having a non-smooth surface portion in the cushion body cover according to the present invention, the cushion body can be easily housed in the bag body, but the air permeability of the cushion body is not impaired as much as possible. Can be.

The cushion body cover according to the present invention is a cushion body cover that accommodates a substantially plate-shaped cushion body having a thickness direction in the vertical direction so as to cover at least a side surface, and both the upper surface and the lower surface of the accommodated cushion body. Alternatively, one of them may be exposed in its entirety. By covering at least the side surface of the cushion body with the cushion body cover, for example, a plurality of cushion bodies are formed on a bag body (for example, the above-mentioned mattress cover provided with a series of zippers on three connecting three-direction side surfaces) that can open and close the upper surface. When the cushion body covers are interposed so as to be fitted from above, it is possible to prevent the side surfaces of the cushion body from being caught and the side surfaces of the cushion body and the inner surface of the bag body from being caught. As a result, the cushion body (the cushion body housed in the cushion body cover) can be smoothly housed in the bag body.
