Description

  The present invention relates to a cushion used for bedding and the like, and more particularly, to a cushion such as bedding using a three-dimensional three-dimensional network as a base cushion.

  Conventionally, a monofilament made of an elastic synthetic resin has a three-dimensional three-dimensional network structure that is irregularly curled or bent and is made of an elastic body having a predetermined thickness in which the filaments are joined to each other at an entanglement point. Bedding mats using cushions are in practical use.

  However, in this type of conventional mat, since the filament is formed by a linear body made of elastic synthetic resin, the filament is not formed even if the mat is covered with a net-like outer cover because the end has a hard rod shape. The cover material may be penetrated and the skin may be stimulated during use. In order to solve this problem, Japanese Patent Application Laid-Open No. 2014-133047 (Patent Document 1) stores a three-dimensional structure network in a bag-like inner cover having a strength that does not penetrate the end of a continuous filament. Is disclosed.

  However, since the three-dimensional structure network is formed of elastic synthetic resin striatum, the striatum may irritate the skin through the cover and feel pain, and the body moves. Occasionally, the filaments shift and generate sound, which may interfere with comfortable sleep. Further, for example, when used as a nursing bed, it is necessary to overlap a cushion material such as urethane foam in order to avoid skin irritation. However, this cushion material may generate odor because it becomes a hotbed of bacteria, but it is difficult to clean the entire cushion material, and there is a problem that it is necessary to temporarily apply a deodorant. It was.

  The problem to be solved by the present invention is to provide a cushion such as a bedding to which antibacterial and deodorizing functions are imparted while obtaining a comfortable cushioning property while improving the sleeping comfort.

  Therefore, a cushion for bedding or the like according to the present invention is a regular cushion made of natural rubber foamed on a three-dimensional mesh cushion composed of a three-dimensional three-dimensional network having elasticity formed by three-dimensionally bending an elastic synthetic resin filament. The gist is that a latex cushion having resilience is placed and a fiber sheet containing phthalocyanine is coated on the latex cushion.

  Further, the three-dimensional three-dimensional structure network is divided into three parts in the longitudinal direction, and has different hardnesses corresponding to the head, buttocks, and feet of the human body.

  Furthermore, the latex mat has a large number of holes formed in the thickness direction.

  The cushion of the bedding and the like according to the present invention has a latex cushion placed on a three-dimensional reticulated cushion composed of a three-dimensional three-dimensional reticulated structure. Since the latex cushion prevents the sound generated by the filament from changing, it is possible to obtain a comfortable cushioning property and a good sleeping comfort. Moreover, since the latex cushion has normal rebound, it has a body pressure dispersibility that lifts evenly with a repulsive force according to the amount of sinking, regardless of the weight of the person's part. Pain caused by physical pressure can be reduced. In addition, since the three-dimensional mesh cushion under the latex cushion has high resilience cushioning and body pressure dispersibility, the cushion function of the latex cushion and three-dimensional mesh cushion provides a comfortable cushion. Can do. Furthermore, since the fiber sheet containing phthalocyanine is coated on the latex cushion, the antibacterial and deodorizing functions of the phthalocyanine can prevent the generation of odors and the growth of bacteria in advance. Even when used as a bed, a hygienic cushion can be configured.

  In addition, since the three-dimensional structure network is divided into three in the longitudinal direction so as to correspond to the head, buttocks, and feet of the human body, sinking due to the weight according to the body part Since the amount can be reduced, the entire body becomes a substantially equal amount of sinking, which makes it easy to turn over while sleeping.

  Further, since a large number of holes are formed in the thickness direction of the latex cushion, it is possible to flexibly follow the stress in the lateral direction, and thus it is possible to eliminate the deviation that causes the floor slip. In addition, since a large number of holes communicate with the three-dimensional reticulated cushion under the latex cushion, the air permeability of the three-dimensional reticulated cushion is not impaired, and the air permeability of the entire cushion can be ensured.

  It is a perspective view which shows the Example of the cushion by this invention.   It is a partial cross section perspective view of the cushion shown in FIG.   It is a body pressure distribution map which shows the body pressure dispersion | distribution state by a cushion.   It is a cross-sectional perspective view which shows the Example which applied the cushion to the pillow.   It is sectional drawing which shows the example which applied the cushion to the chair.

  The cushion of bedding and the like according to the present invention is a regular repulsion made of natural rubber foamed on a three-dimensional mesh cushion consisting of a three-dimensional three-dimensional mesh network having three-dimensionally bent elastic synthetic resin filaments. A latex cushion having a phthalocyanine content is coated on the latex cushion.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 and FIG. 2 show a cushion 1 for a bed bud, which is based on a three-dimensional net-like cushion 2, on which a latex cushion 3 is placed, and on the latex cushion 3, a fiber sheet 4 is coated. Has been. The three-dimensional mesh cushion 2, latex cushion 3, and fiber sheet 4 are overlaid and covered with a duvet cover 5.

  The three-dimensional net-like cushion 2 is made of an elastic synthetic resin (polyether ester fiber or the like, and is formed by twisting a solid or hollow continuous linear body made of an elastic synthetic resin to form a large number of linear body loops, A three-dimensional structure network in which striate loops are joined to each other, and has the necessary elastic force and air permeability. It is formed into a rectangular flat plate with a thickness of about 1 cm to 10 cm by a large number of striate loops winding the body, and the density of the three-dimensional structure network is about 20 kg to 40 kg / cubic meter. A desired hardness or repulsive force can be obtained by this density, and a commercial product name “breath air” (manufactured by Toyobo Co., Ltd.) is used as the solid mesh cushion 2. It can be.

  The latex cushion 3 is a latex foam obtained by foaming natural rubber, and is formed in a rectangular flat plate having a thickness of about 1 cm to 10 cm. The latex cushion 3 sinks by the same ratio as the weight, and has a repulsive property that repels from the inside with a force equivalent to the pressure. Furthermore, the latex cushion 3 is formed with a large number of holes 3a in an aligned state in the thickness direction. The large number of holes 3a can flexibly follow the stress in the lateral direction. As the latex cushion 3, a trade name body doctor (manufactured by Global Sangyo Co., Ltd.) can be used.

  The fiber sheet 4 is a sheet containing a metal phthalocyanine made of a blue / green color pigment compound by dyeing it into a woven fabric or non-woven fabric, and is known to have anti-allergic substances, deodorizing and antibacterial deodorizing functions. It has been. The fiber sheet 4 is formed in a rectangular plate having a thickness of about 1 mm which is the same as or slightly larger than the three-dimensional mesh cushion 2 and the latex cushion 3 described above. The fiber sheet 4 can use a brand name allele catcher (manufactured by Daiwabo Neu Co., Ltd.).

  Further, as shown in FIG. 1, the three-dimensional mesh cushion 2 is divided into three in the longitudinal direction, and each three-dimensional mesh cushion is preferably housed in a cover having air permeability. By connecting one side of this cover, the three-dimensional net-like cushion 2 can be folded in three. As shown in FIG. 3, the three-dimensional mesh cushion 2 divided into three in the longitudinal direction has different hardnesses corresponding to the head A, the buttocks B, and the feet C of the human body. For example, when used for a bed bud, since the buttocks B are heaviest when a person is sleeping, the central three-dimensional mesh cushion 2b is hardened and the three-dimensional mesh cushions 2a and 2c before and after are softened. As a result, the amount of sinking due to the weight of the buttocks is reduced, so that the entire body has a substantially uniform sinking amount. This makes it easy to turn over while sleeping.

  When the cushion 1 configured as described above is used for a bed bud, the latex cushion 3 sinks in accordance with the body shape and weight of the body due to the normal repulsion, and the body pressure is dispersed as shown in FIG. Body pressure is eliminated. Furthermore, when a person is displaced in the horizontal direction, the numerous holes 3a formed in the latex cushion 3 softly follow the stress in the lateral direction, so that the addition to the skin is reduced. Furthermore, the three-dimensional mesh cushion 2 receives the whole body weight by elasticity and supports the body in a body pressure dispersion state. On the other hand, odors or bacteria generated from people or the cushion 1 are reduced by the fiber sheet 4 containing metal phthalocyanine having antibacterial and deodorizing functions. These synergistic effects provide comfortable cushioning and good sleeping comfort.

  FIG. 4 shows an example applied to a pillow as another embodiment of a cushion such as bedding. The pillow 10 is arranged so that the latex cushion 12 is sandwiched between the upper and lower sides of the three-dimensional mesh cushion 11 arranged in the center in the height direction. Furthermore, the surface of the latex cushion 12 is covered with a fiber sheet 13. The three-dimensional mesh cushion 11, the latex cushion 12, and the fiber sheet 13 are the same as those for the bed bud described above. In the case of the pillow 1, the optimum height differs depending on the person, so that in the pillow 10 shown in FIG. 4, two three-dimensional net-like cushions 11 are stacked, but one may be used. The thickness of the mesh cushion 11 or the latex cushion 12 may be changed to an appropriate thickness.

  Even when applied to such a pillow 10, the latex cushion 11 sinks in accordance with the weight of the head due to the repulsive nature of the latex cushion 11, and further formed in the latex cushion 11 even when the head is displaced in the horizontal direction. Since the large number of holes softly follow the lateral stress, the addition to the skin is reduced. Furthermore, since the bad odor can be eliminated by the antibacterial and deodorizing functions of the fiber sheet 13 containing metal phthalocyanine, a comfortable cushioning property and a good sleeping comfort can be obtained.

  FIG. 5 is an application example of a cushion, and shows an example applied to a chair. The chair 20 includes a seat portion 21, four leg portions 22 that support the seat portion 21, and a backrest 23 that is erected from the rear end of the seat portion 21. The seat portion 21 is formed in a substantially square shape, and a cushion 24 is placed on the upper surface. In the cushion 24, a latex cushion 26 is placed on a three-dimensional mesh cushion 25 and a fiber sheet 27 is coated on the latex cushion 26, as in the case of the bed bud described above. The three-dimensional mesh cushion 25, the latex cushion 26, and the fiber sheet 27 are the same as those for the bed pad described above and will not be described in detail. However, since the three-dimensional mesh cushion 25 is heavily loaded per unit area, the bed pad described above is used. What is harder than the three-dimensional reticulated cushion for use is preferable.

  Even when applied to such a chair 20, the latex cushion 26 sinks according to the shape and weight of the buttocks according to the repulsive nature of the latex cushion 26, and the body pressure due to the tailbone of the seated person 30 is dispersed. Is avoided, and this also reduces the feeling of fatigue and pain.

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. In the embodiment described above, the three-dimensional net-like cushion is divided into three in the longitudinal direction. However, the latex cushion and the fiber sheet may be similarly divided into three according to this, and each may be stored in the cover. Further, the numerous holes formed in the latex cushion may not be penetrated in the thickness direction but may be stop holes having a depth of 1/2 or more on the upper side of the cushion.
