Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cushion device used for a mattress for a bed, a sofa, a chair, a vehicle seat, and the like.
[0002]
[Prior art]
For example, a mattress for a bed, which is a cushion device, requires a function of elastically supporting a human body without impairing a comfortable sleeping comfort, that is, good cushion performance.
[0003]
The mattress has a cushion body, and is formed by laminating sheet-like elastic materials on the upper and lower surfaces of the cushion body, and covering the laminated body with an exterior ground. As the cushion body, a spring unit is often used. The spring unit is formed by connecting a large number of coil springs in a matrix with helical wires.
[0004]
In the case of a mattress in which the cushion body is formed by a coil spring, the coil spring generates a repulsive force according to the amount of deformation when the coil spring is compressed and deformed under the load of the user. Your body may be under pressure and your comfort may be impaired.
[0005]
It has been proposed that the cushion body is formed of a gelled material instead of a coil spring. Cushion body made of gelled material has a high heat capacity and high efficiency heat transfer, so the touch may be cold, the manufacturing cost may be high, or even in a more restrained state In some cases, there is no buffering force, and it is not suitable for forming a cushion body.
[0006]
Therefore, as shown in US Pat. No. 5,749,111, a plurality of hollow pillars surrounded by a partition wall are formed on a cushion body formed of a gelled material as described above. The problem is being solved.
[0007]
[Problems to be solved by the invention]
According to the cushion body having such a structure, since the partition wall is bent by a load, it has an advantage of excellent buffering properties. However, since the bent partition wall has a small repulsive force, a user who is supine on the cushion body sometimes sinks a heavy part of the body deeply and it is difficult to turn over.
[0008]
An object of the present invention is to provide a cushion device that hardly causes a repulsive force against a load and that makes it easy for a user to turn over.
[0018]

[0025]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0026]
1 to 5 show a first embodiment of the present invention. FIG. 1 shows a bed mattress 1 as a cushion device. The mattress 1 is a spring unit 101 and a cushion laminated on the upper surface of the spring unit 101 via a sheet-like upper protective material 102 such as a nonwoven fabric or a sisal. A main body 2 is provided.
[0027]
As shown in FIG. 2, the spring unit 101 has a large number of coil springs 103 arranged in a matrix, and the upper end surface and the lower end surface of adjacent coil springs 103 are connected to each other by a helical wire 104.
[0028]
Frame lines 105 are attached to the peripheral edge portions of the upper and lower surfaces of the spring unit 101 by clips 106. Further, a lower protective material 107 is joined to the lower surface of the spring unit 101.
[0029]
The upper protective material 102 and the lower protective material 107 are attached to the spring unit 101 together with the frame line 105 by the clip 106 at the periphery.
[0030]
The cushion body 2 is divided into a plurality of blocks 3. In this embodiment, the cushion body 2 is divided into nine blocks 3 as shown in FIGS.
[0031]
The block 3 includes an outer partition wall 4 formed in a rectangular frame shape by an elastic material such as an elastomer, and an inner partition wall 5 provided in the outer partition wall 4 in a lattice shape. This block 3 is usually injection-molded.
[0032]
The shape of the lattice is 50 to 300 mm in height of the partition wall 5 and 20 to 200 mm in width of the partition wall 5. The thickness of the partition walls 4 and 5 is 0.5 mm to 5 mm, preferably 1.5 to 3 mm. Even if the partition wall is made thin by using an elastomer having a high hardness, or on the contrary, if the partition wall is made thick by using an elastomer having a low hardness, natural cushioning properties are lost when sleeping. The hardness of the elastomer and the thickness of the partition walls are important factors for providing a soft and natural cushioning property without bottoming out against the weight of the human body. From this point of view, it is preferable to use an elastomer having a hardness of Shore A25 to 35 for the partition walls and to set the thickness of the partition walls to 1.5 to 3.0 mm.
[0033]
The elastomer used in the present invention is a thermoplastic elastomer or rubber. A thermoplastic elastomer is a substance that behaves as a rubber-like elastic body at room temperature but undergoes compositional deformation as the temperature rises. As thermoplastic elastomers, polystyrene-based thermoplastic elastomers, polyolefin-based thermoplastic elastomers, polyvinyl chloride-based thermoplastic elastomers, polyester-based thermoplastic elastomers, polyurethane-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, 1,2-polybutadiene-based Examples thereof include thermoplastic elastomers, fluororubber-based thermoplastic elastomers, chlorinated polyethylene-based thermoplastic elastomers, and dynamically crosslinked thermoplastic elastomers.
[0034]
Moreover, natural rubber and synthetic rubber are used as rubber. Examples of the synthetic rubber include polybutadiene rubber, polyisoprene rubber, butadiene styrene rubber, butadiene acrylonitrile rubber, and isobutylene rubber.
[0035]
Of the above-described elastomers, polystyrene-based thermoplastic elastomers are particularly preferable for forming the cushion body 2 because they are flexible and have good durability.
[0036]
The plurality of blocks 3 are arranged by joining adjacent outer partition walls 4, and the surfaces of the outer partition walls 4 that are joined to each other are partially or entirely bonded and fixed by an adhesive.
[0037]
As the adhesive, for example, a synthetic rubber adhesive having flexibility at the time of curing is used. As a result, the nine blocks 3 are joined together, and the flexibility of the outer partition 4 bonded and fixed by an adhesive is not impaired.
[0038]
As shown in FIG. 2, frame lines 7 are attached to the peripheral edges of the upper surface and the lower surface of the cushion body 2 by C-shaped clips 8 over the entire length.
[0039]
A side elastic member 11 formed in a frame shape is provided on the outer peripheral surface of the cushion body 2 over the entire length. The side elastic material 11 is formed of a foamed synthetic resin such as urethane foam, the cross-sectional shape is rectangular, and the height is substantially the same as that of the cushion body 2.
[0040]
As shown in FIGS. 3 and 4, the upper surface and the outer surface of the side elastic member 11 are covered with one end of a flange cloth 13 as a holding means. One end of the flange cloth 13 is connected and fixed to the peripheral edge of the upper surface of the cushion body 2 by a C-shaped clip 8 together with the frame line 7, and the midway part is connected to the upper peripheral edge of the spring unit 101 by the clip 106 together with the frame line 105. ing. And the other end part of the flange cloth 13 covers the outer peripheral surface of the spring unit 101, and the end is connected and fixed to the exterior body 18 mentioned later.
[0041]
Thereby, the spring unit 101, the cushion main body 2, the side elastic member 11, and the exterior body 18 are integrated. In addition, the said flange cloth 13 is provided in the width direction both sides of the cushion main body 2, as shown in FIG.
[0042]
On the upper surface of the cushion body 2 and the side elastic member 11, a mesh 15 is laminated as a sheet-like member, which is molded from a synthetic resin. The mesh 15 has a function of dispersing a load applied to the upper surface of the cushion body 2.
[0043]
On the upper surface of the mesh 15, a sheet-like upper surface elastic material 16 such as urethane foam is provided. The peripheral portion of the upper elastic member 16 is bonded and fixed to the upper surface of the side elastic member 11 through the mesh 15.
[0044]
The lower end surface of the cushion body 2, that is, the lower end surfaces of the outer partition wall 4 and the inner partition wall 5 of the block 3 are bonded and fixed to the upper surface of the upper protective material 102. Thereby, the cushion body 1 is integrally coupled to the upper surface elastic member 16, the upper protective member 102, and the side elastic member 11.
[0045]
The spring unit 101 and the cushion main body 2 are covered with the exterior ground 18. The exterior ground 18 includes an upper mirror portion 18a that covers the upper elastic member 16, a lower mirror portion 18b that covers the lower surface of the spring unit 101, and upper and lower end portions of the upper mirror portion 18a and the lower mirror portion 18b. It consists of a town portion 18c integrally stitched with a tape 19 at the periphery. And the terminal part of the said flange cloth 13 is stitch | sutured integrally at the stitching | suture location of the lower mirror part 18b and the town part 18c.
[0046]
Therefore, the flange cloth 13 connects the exterior body 18 to the spring unit 101 and the cushion body 2. Accordingly, the outer casing 18 is prevented from moving with respect to the spring unit 101 and the cushion main body 2.
[0047]
Further, the flange cloth 13 integrally couples the side elastic member 11 to the cushion body 2. Thereby, the peripheral portion of the cushion body 2 is elastically deformed integrally with the side elastic member 11.
[0048]
When the user U lies on the mattress 1 thus configured as shown in FIG. 5, the outer partition 4 and the inner partition 5 of each block 3 constituting the cushion body 2 are bent and deformed by the load of the user U. To do.
[0049]
The load applied to the upper surface of the cushion body 2 is dispersed by the mesh 15 and prevents the cushion body 2 from partially falling down. Further, frame lines 7 are provided at the peripheral portions of the upper and lower surfaces of the cushion body 2. Therefore, the outer partition 4 and the inner partition 5 of each block 3 of the cushion main body 2 are prevented from being bent locally by the mesh 15 and are bent and deformed almost integrally by the upper frame line 7. That is, since the outer partition 4 and the inner partition 5 of each block 3 are bent and deformed substantially uniformly, the user can obtain a comfortable sleeping comfort.
[0050]
When the cushion body 2 is compressed and deformed by the load applied to the mattress 1, the side elastic member 11 integrally held by the flange cloth 13 on the outer peripheral surface of the cushion body 2 is also integrally compressed and deformed. In other words, the cushion body 2 is prevented from being bent and deformed by the frame line 7 so that the peripheral portion is larger than other portions.
[0051]
The cushion body 2 is provided on the spring unit 101. Therefore, even if the outer and inner partitions 4 and 5 of the block 3 of the cushion body 2 are bent and deformed by the load of the user who is supine on the mattress 1, the user's body is elastically supported by the spring unit 101. The
[0052]
Since the user's body is elastically supported by the spring unit 101, it is possible to prevent a heavy part such as a buttocks of the user's body from sinking too deeply. Thereby, even if the repulsive force of the cushion body 2 is small, the user can turn over relatively easily.
[0053]
The low repulsive force of the cushion body 2 acts on the user's body, and the high repulsive force of the spring unit 101 does not directly act on the user's body. Therefore, the user is hardly pressed by the repulsive force of the spring unit 101.
[0054]
Further, by providing the cushion body 2 on the spring unit 101, the height of the cushion body 2, that is, the outer partition wall 4 and the inner partition wall 5 that form the block 3, without deteriorating the cushion performance as the mattress 1. The height dimension can be reduced. Thereby, even if the spring unit 101 and the cushion main body 2 have a double structure, the thickness of the mattress 1 can be made relatively thin.
[0055]
When the load is removed from the mattress 1, the compressed and deformed side elastic member 11 is restored, and the restoring force is transmitted to the upper frame line 7 of the mattress body 2 through the flange cloth 13. The cushion body 2 is restored by the frame 7. That is, the outer partition wall 4 and the inner partition wall 5 of each bent block 3 are restored by the restoring force of the side elastic member 11 as well as the restoring force provided therein.
[0056]
Therefore, even if the restoring force of each block 3 formed by the thin outer partition wall 4 and the inner partition wall 5 is weak, the cushion body 2 is bent by the outer partition wall 4 of each block 3 by the restoring force of the side elastic member 11. Therefore, the mattress 1 can be provided with good performance.
[0057]
When the restoring force of the side elastic member 11 is large, the restoring force presses the body of the user who is supine on the mattress 1. Therefore, by changing the elasticity (hardness) of the side elastic member 11 according to the foaming rate or the like, the cushion body 2 that has been bent and deformed can be reliably restored, and the user's body is not strongly compressed. Can be elastic.
[0058]
The cushion body 2 is divided into a plurality of blocks 3, and these blocks 3 are integrally connected by a first synthetic rubber adhesive 6. Therefore, the block 3 divided into a plurality of parts can be formed with a small mold as compared with the case where the cushion main body 2 is formed as one block, and therefore the manufacture thereof can be performed easily and inexpensively.
[0059]
6 to 8 show a second embodiment of the present invention. In the second embodiment, among the frame lines 7 provided on the periphery of the upper surface and the lower surface of the cushion body 2, a rectangular shape smaller than the frame line 7 is formed within the frame line 7 on the lower surface. A plurality of auxiliary frame lines 65, in this case, two auxiliary frame lines 65 are provided.
[0060]
The cushion body 2 is configured by arranging a plurality of blocks 3 having a substantially square planar shape. In this embodiment, 5 vertical blocks 3 horizontal blocks 3 are arranged in a matrix. The auxiliary frame line 65 is formed in a rectangular frame shape having a width dimension corresponding to the width dimension of one block 3 and a length dimension corresponding to the width dimension of three blocks 3.
[0061]
The outer partition walls 4 to be joined to each other of the blocks 3 are joined and fixed by a synthetic rubber adhesive or ultrasonic welding as in the first embodiment.
[0062]
Each auxiliary frame line 65 is installed along the width direction on the lower surface of the second and fourth blocks 3 in the vertical direction of the cushion body 2, and both sides in the width direction of each auxiliary frame line 65 are joined in the vertical direction. A U-shaped clip 66 is connected to the lower ends of the outer partition walls 4 of the two rows of blocks 3. The frame line 7 is attached to the outer partition 4 by a C-shaped clip 8.
[0063]
That is, one auxiliary frame line 65 integrally connects three columns 3 in the vertical direction (a total of nine blocks 3). Further, both ends of the auxiliary frame line 65 in the longitudinal direction are connected and fixed to the both sides of the frame line 7 by clips 67 respectively.
[0064]
In this way, the lower end portions of the outer partition walls 4 of the plurality of blocks 3 constituting the cushion body 2 are connected by the frame line 7 and the two auxiliary frame lines 65, so that the plurality of adjacent blocks 3 are strengthened. Can be linked to.
[0065]
Therefore, when the cushion main body 2 is formed by a plurality of blocks 3, it is possible to prevent the connected state of the blocks 3 from being damaged by long-term use.
[0066]
In addition, the auxiliary frame 65 provided on the lower surface of the cushion body 2 has a function of maintaining the shape of each block 3 and supporting the weight, so that the shape of the cushion body 2 is impaired during transportation or carrying. Can be prevented.
[0067]
In the second embodiment, the outer partition walls 4 of the blocks 3 adjacent in the width direction of the cushion body 2 are joined and fixed by an adhesive or ultrasonic welding, and the outer partition walls 4 of the blocks 3 adjacent in the longitudinal direction are assisted. The frame 65 may be connected and fixed.
[0068]
9 to 11 show a third embodiment of the present invention. In this embodiment, the inner peripheral surface of the frame-shaped side elastic member 11 provided on the outer periphery is bonded and fixed to the outer peripheral surface of the cushion body 2.
[0069]
That is, in place of the flange cloth 13 as the holding means shown in the first embodiment, the cushion body 2 bent and deformed by the load of the user by bonding and fixing the cushion body 2 and the side elastic material 11. The restoring force of the side elastic member 11 is applied to the partition walls 4 and 5 of the block 3 so that the cushion body 2 can be reliably restored to the original shape.
[0070]
In the third embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
[0071]
FIG. 12 shows a fourth embodiment of the present invention. In this embodiment, nine blocks 3 constituting the cushion body 2 are provided, and the outer partition walls 4 and the inner partition walls 5 of the three blocks 3A in the horizontal row located in the center in the longitudinal direction are harder than the partition walls of the other blocks. did.
As means for making the partition walls 4, 5 of the block 3 A harder than the partition walls 4, 5 of the other blocks 3, the elastic material forming the three blocks 3 A is a material harder than the elastic material forming the other blocks 3. When the blocks 3 and 3A are formed of the same material, the partition walls 4 and 5 of the block 3A are made thicker than the partition walls 4 and 5 of the other blocks 3. It is possible.
[0072]
FIG. 13 shows a fifth embodiment of the present invention. In this embodiment, the cushion body 2 is formed by juxtaposing three blocks 3B having a length over the entire length in the longitudinal direction. The longitudinal direction of each block 3B is shown in FIG. The inner partition wall 5 provided in the midway part is provided denser than other parts. Thereby, the midway part in the longitudinal direction of the cushion body 2 can be made harder than the other parts.
If the central part in the longitudinal direction of the cushion body 2 is made harder than the other parts as in the fourth and fifth embodiments, the height of the cushion body 2 can be increased without increasing the height of the cushion body 2. It becomes possible to support the heaviest buttocks relatively well.
[0073]

In the sixth embodiment shown in FIG. 14, the frame line 7 is not provided at the peripheral edge portion between the upper surface and the lower surface of the cushion body 2, and one end of the flange cloth 13 is attached to the peripheral edge portion on the upper surface side of the cushion body 2 by the clip 8. Directly connected and fixed.
[0074]
In FIG. 15, the frame line 7 is provided only at the peripheral edge of the upper surface of the cushion body 2, and one end of the flange cloth 13 is integrally coupled to the frame line 7 and the upper end of the outer partition wall 4 of the cushion body 2 by the clip 8. did.
16 (a) to 16 (c) are modifications of the block forming the cushion main body 2 according to the eighth embodiment of the present invention. In the block 3B of this embodiment, the outer partition wall 4a and the inner partition wall 5a are formed in a tapered shape so that the thickness gradually increases from the upper end to the lower end, and the upper part of each partition wall 4a, 5a is passed through the upper part. Hole 111 was drilled.
[0075]
The through hole 111 communicates with the space defined by the partition walls 4a and 5a, and communicates with the outside through the through hole 111 formed in the outer partition wall 4a.
[0076]
When the thickness of each partition wall 4a, 5a becomes a taper shape that becomes thicker toward the lower end, the upper end portions of the partition walls 4a, 5a are easily bent as shown in FIG. A soft feel can be given to the user U, and since the lower end portion is thick, it is difficult for the lower end portion to be bent, so that the cushion body 2 can support the user's body well. Become.
[0077]
Further, since the through holes 111 are formed in the respective partition walls 4a and 5a, when the cushion body 2 is compressed and deformed, air smoothly flows from the through holes 111 as indicated by arrows in the drawing, so that the air is discharged. Since the sound can be prevented and the partition walls 4a and 5a can be easily deformed, the feel given to the user can be softened.
[0078]
