Description

  The present invention relates to a mattress, and particularly to a mattress excellent in breathability and elasticity.

Ideal sleep greatly contributes to a person's health and spirit and can result in a rich life.
And it is said that a person drains about 1 liter of water as a sweat during sleep, but in order to absorb this sweat smoothly and to obtain a comfortable sleep, it is applied to bedding such as a mattress. Has been devised in various ways.

  By the way, conventionally, mattresses using cotton-like materials, polyurethane, non-woven fabrics, etc. are known, and in order to improve air permeability and elasticity as required conditions, a surface in contact with a human body is required. Less, that is, by supporting a person with a small number of support portions, air permeability can be ensured and appropriate elasticity can be imparted.

However, the conventional mattress has a problem that “sag” occurs in the constituent material as it is used, and air permeability and elasticity are lowered.
In addition, in the case of conventional mattresses, it is necessary to increase the density of the constituent materials in order to make it difficult for “sagging” to occur, but this increases the weight of the mattress itself and makes it difficult to bend, for example during storage. There was a problem that it became difficult to handle.

  In view of the problems of the above-mentioned conventional mattress, the present invention is less prone to “sagging” even when used for a long period of time, can maintain air permeability and elasticity in a good state, and can be used during storage. A first object is to provide a mattress that is easy to handle.

  In addition, a second object of the present invention is to provide a mattress that can cope with partial “sagging” caused by long-term use.

  In order to achieve the first object, the mattress of the present invention is provided on the surface of the core material layer, a core material layer comprising a cross-linked polyethylene foam layer and a solid cotton layer having a closed cell structure having irregularities on the surface, A mattress comprising a tick-proof sheet layer and a charcoal sheet layer containing charcoal powder and covered with a duvet cover, and a plurality of small circular through-holes on the entire surface of the cross-linked polyethylene foam layer of the core layer A slit-like through hole extending in the longitudinal direction of the mattress is formed in parallel with the width direction of the mattress at the folding position of the mattress.

  Furthermore, in order to achieve the second object, the mattress of the present invention is formed with a pocket-shaped storage section that can store auxiliary core members extending in the width direction of the mattress at a plurality of locations in the longitudinal direction of the mattress of the duvet cover. It is characterized by that.

  According to the mattress of the present invention, the cross-linked polyethylene foam layer constituting the core layer of the closed cell structure having irregularities on the surface and a large number of small circular through-holes on the entire surface can be used even for a long time. It is possible to prevent the occurrence of “sagging” and maintain air permeability and elasticity in a good state. In addition, the cross-linked polyethylene foam layer has a low density, so that the weight of the mattress itself can be reduced, and slit-like through holes extending in the longitudinal direction of the mattress are arranged in parallel with the width direction of the mattress. Therefore, it is possible to provide a mattress that is easy to bend and easy to handle during storage.

  In addition, by forming pocket-shaped storage sections that can store auxiliary core materials extending in the width direction of the mattress at a plurality of locations in the longitudinal direction of the mattress of the futon cover, partial “sagging” is caused by long-term use. By storing the auxiliary core material in the storage portion of the generated location, the location where “sagging” has occurred can be easily restored, and a good use state can be maintained.

One Example of the mattress of this invention is shown, (a) is the top view which made a part a cross section, (b) is XX sectional drawing of (a). (A) is a plan view, (b) is a bottom view, and (c) is a bottom view of a mattress of a modified embodiment.

  Hereinafter, embodiments of a mattress according to the present invention will be described with reference to the drawings.

1 to 2 show an embodiment of a mattress of the present invention.
As shown in FIG. 1, this mattress 1 is provided on a surface of a core material layer including a cross-linked polyethylene foam layer 2 and a solid cotton layer 3, 3 </ b> A having a closed cell structure having irregularities 21 on the surface thereof. A mattress 1 comprising a tick-proof sheet layer 4 and a charcoal sheet layer 5 containing charcoal powder and covered with a duvet cover 6.
Then, a large number of small circular through holes 22 are formed on the entire surface of the cross-linked polyethylene foam layer 2 constituting the core material layer, and slit-like through holes 23 extending in the longitudinal direction of the futon 1 at the folding position of the futon 1 are laid. These are formed in parallel in the width direction.

  Further, in the mattress 1 of this embodiment, the core material layer is configured by arranging the solid cotton layers 3 and 3A on both sides of the cross-linked polyethylene foam layer 2, and further on the back side of the core material layer. The tick sheet layer 4A and the charcoal sheet layer 5A containing charcoal powder are disposed. These layers, specifically, for example, the charcoal layer 3, the tick-proof sheet layer 4A, and charcoal containing charcoal powder. Any or all of the sheet layers 5A may be omitted as necessary.

The cross-linked polyethylene foam layer 2 having a closed cell structure constituting the core material layer is formed by foaming a polyethylene sheet cross-linked with a chemical cross-linking agent. The thickness including the surface irregularities 21 is about 20 to 50 mm, and the expansion ratio By appropriately setting (usually several times to several tens of times), a core layer that can maintain “elasticity” of the mattress 1 in a good state without being “sagging” even after long-term use. It can be.
Further, the unevenness 21 on the surface of the cross-linked polyethylene foam layer 2 is formed such that unevenness having a height difference of about 10 to 20 mm is formed in a zigzag pattern at a pitch of about 30 to 50 mm, and the diameter is formed at the center of the recess. A small circular through hole 22 of about 1 to 5 mm is formed.
The unevenness can also be formed on the back surface as necessary.
Moreover, the slit-like through-hole 23 has a width of about 5 to 10 mm at the folding position when the mattress 1 is folded, in the present embodiment, at 1/3 and 2/3 positions in the longitudinal direction of the mattress 1. The slit-shaped through-holes 23 are formed at a pitch of about 30 to 60 mm.
The cross-linked polyethylene foam layer 2 having a closed cell structure constituting the core layer is composed of a cross-linked polyethylene foam layer 2 having a closed cell structure having irregularities 21 on the surface and a large number of small circular through holes 22 on the entire surface. Therefore, “sagging” hardly occurs even after long-term use, and the breathability and elasticity of the mattress 1 can be maintained in a good state. The cross-linked polyethylene foam layer 2 has a low density (about 60% of the density of solid cotton formed by heating and compressing a polyester cotton material), thereby reducing the weight of the mattress 1 and the mattress 1 By forming slit-like through-holes 23 extending in the longitudinal direction of the mattress in parallel in the width direction of the mattress, the mattress 1 can be easily folded and handled during storage.

Similarly, as the solid cotton layers 3 and 3A constituting the core material layer, for example, those having a thickness of about 10 to 20 mm formed by heating and compressing a polyester cotton material can be used.
Solid cotton using this polyester cotton material consists of two or more types of polyester cotton material and a plurality of thin cotton materials that have a low melting point binder fiber compared to this polyester cotton material in the form of a sheet using existing cotton making equipment. It can be processed into solid cotton by heating, pressure bonding and cooling.
The solid cotton layer 3 constituting the core material layer is less likely to “sag” even when used for a long period of time, and can maintain the breathability and elasticity of the mattress 1 in a good state.

The anti-tick sheet layers 4 and 4A are made of a non-woven sheet containing fibers that have been subjected to anti-tick processing, and for example, about 0.5 to 5 mm can be used.
To mite processing, repellent insecticides such as toluamide compounds and nicotine compounds are used, and insecticides such as pyrethroid compounds and organophosphorus compounds are used. it can.
The tick-proof sheet layers 4 and 4A can prevent mites from invading into the mattress 1 and breeding without directly touching the human body.

The charcoal sheet layers 5 and 5A are made of a sheet made of nonwoven fabric containing fine charcoal powder such as charcoal, for example, Bincho charcoal and bamboo charcoal.
The charcoal sheet layers 5 and 5A have a function of removing sweat and the like by the deodorizing effect of charcoal, the adsorbing effect of harmful substances, the self-cleaning regenerating effect of adsorbed substances, and the like, and the mattress 1 can be always kept clean. Like that.
In addition to the thermal insulation effect obtained by far infrared rays generated from charcoal, the mind can be stabilized by negative ions generated from charcoal, and a relaxation effect can be obtained.

  The futon cover 6 can use a quilting material other than a normal cloth.

Further, as shown in FIG. 2, this mattress 1 is a futon that is likely to cause partial “sagging” due to a person's weight applied through the back and buttocks (waist) due to long-term use of the mattress 1. In a plurality of longitudinal positions of the mattress 1 of the cover 6, that is, the mattress 1 of this embodiment, as shown in FIG. 2 (b), approximately 1/4, 1/2, and 3/4 of the longitudinal direction of the mattress 1 are provided. Pocket-shaped storage portions 61 that can store auxiliary core members 7 extending in the width direction of the mattress 1 are formed at three positions.
Here, the position and size for forming the storage portion 61 can be set as appropriate according to the size of the mattress 1 and the like, so that it can be easily adapted to the position of a person's buttocks (waist). ), The length of the mattress 1 at the intermediate position in the longitudinal direction of the mattress 1 is two, so that a total of four places are formed, or the width of the mattress 1 at the intermediate position of the mattress 61 in the longitudinal direction It can also be formed larger than the storage portion 61 (not shown).
As the auxiliary core material 7, a nonwoven fabric such as solid cotton having a width of about 200 to 400 mm in the longitudinal direction of the mattress 1 and a thickness of about 10 to 20 mm can be used, and the storage unit 61 can store the auxiliary core material 7. Make it to the size.
By forming the pocket-shaped storage portion 61 that can store the auxiliary core material 7 extending in the width direction of the mattress 1, the auxiliary core material is provided in the storage portion 61 where partial “sagging” occurs due to long-term use. By storing 7, the place where “sagging” has occurred can be easily restored, and a good state of use can be maintained.

  As described above, the mattress of the present invention has been described based on the embodiments thereof. However, the present invention is not limited to the configurations described in the above embodiments, and the configurations may be appropriately changed without departing from the spirit of the present invention. It is something that can be done.
