Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion mat used for bedding, and more particularly, the present invention relates to a cushion mat using a plurality of rolls of cushion material as core materials.

[0002]

2. Description of the Related Art Conventionally, a cushion mat having the structure shown in FIG. 8 has been proposed. This cushion mat includes a frame plate 30, a front plate 31, a back plate 32, each of which is made of a cushion material such as urethane foam.
And a plurality of rolls 33 are used, and a plurality of rolls 33 as a core material are accommodated and arranged in parallel in a recess 34 provided in the frame plate 30, and a top plate and a bottom plate are provided. 31 and the back plate 32 are overlapped and integrally joined. In the figure, 35 is a cover cloth that covers the whole.

When a human body is laid on the cushion mat having such a structure, the semi-rigid front plate 31 is slightly elastically deformed to provide the human body with cushioning properties, and each roll 33 is appropriately adjusted according to the load. It supports the load of the human body while being elastically deformed.

[0004]

However, when the load of the human body acts on each roll 33, each roll 33 tries to elastically deform by crushing the inner hole, but each roll 33 is made of a hard cushion material. Formed,
Since it is in close contact with the adjacent roll, the adjacent roll 33,
As a result, 33 hinders elastic deformation from each other. For this reason, there is a problem in that the user feels hardness and decreases the sleeping comfort.

The present invention has been made in view of the above-mentioned problems, and by making each roll elastically deform with respect to the load, the user does not feel the hardness and a proper cushion is provided. It is an object of the present invention to provide a cushion mat that can provide a comfortable and comfortable sleep.

[0006]

In a cushion mat according to the present invention, a core member is composed of a plurality of rolls made of a cushion material and a roll support plate for supporting the rolls in parallel on the same plane. . On the upper surface of the roll support plate, a plurality of partition walls are provided so as to project at equal intervals, and roll support grooves having a groove width larger than the diameter of the roll are formed between adjacent partition walls.

In the cushion mat according to the second aspect of the present invention, at least each partition of the roll support plate is formed of a cushion material.

In the cushion mat according to the third aspect of the present invention, the roll support plate has a groove formed at the bending position of the cushion mat.

In the cushion mat according to the invention of claim 4, both ends of each roll are joined to the upper surface of the roll support plate.

[0010]

When a load is applied to each roll, each roll is supported in the roll support groove of the roll support plate with some space, so that elastic deformation of the roll is allowed and the user does not feel hardness. Further, since the partition wall of the roll support plate exists between the adjacent rolls, the movement of the rolls is prevented, and the interval between the adjacent rolls does not expand more than necessary and the human body does not feel a gap.

In the cushion mat according to the second aspect of the present invention, since at least each partition of the roll support plate is formed of the cushion material, the partition fills the gap between the adjacent rolls and does not make the human body feel the gap.

In the cushion mat according to the third aspect of the present invention, since the concave groove is formed at the bending position of the cushion mat of the roll support plate, the cushion mat can be easily bent at the concave groove position.

In the cushion mat according to the invention of claim 4, since both ends of each roll are joined to the upper surface of the roll support plate, the rolls are not displaced even when a load is applied.

[0014]

1 to 3 show the structure of a cushion mat according to an embodiment of the present invention. The cushion mat of the illustrated example has a front plate 2 on the upper surface of the frame plate 1 and a back plate 3 on the lower surface thereof.
Each of them has a structure in which a plurality of rolls 6 as a core material 5 and a roll supporting plate 7 are housed and arranged in a recess 4 provided in the frame plate 1 while being polymerized and attached.
In the figure, 8 is a cover cloth which covers the whole.

A thick cushion material such as soft urethane foam is used for the frame plate 1, and both edge portions 1 having a narrow width are used.
A rectangular frame is formed by a and 1b and wide end portions 1c and 1d, and a recess 4 that penetrates vertically is formed in the frame. One end 1c is a portion that supports the head of the human body, and the other end 1d is a portion that supports the toes of the human body.

The front plate 2 and the back plate 3 are made of a cushion material having a corrugated surface on one side. The front plate 2 is
The cushion material such as urethane foam is hardened by impregnating synthetic rubber into the entire cushion and vulcanizing. After the hardening treatment, synthetic rubber is impregnated only on the convex portions of the uneven surface and vulcanized. As a result, it is partially cured. A plurality of permanent magnets 12 are attached to the concave and convex surface of the front plate 2 with an adhesive at positions corresponding to the shape of the human body. The back plate 3 is a cushion material such as urethane foam that is hardened by impregnating synthetic rubber only on the convex portions of the irregular surface and vulcanizing it.

The core material 5 is composed of a plurality of rolls 6 having the same outer diameter and the same length, and a roll support plate 7 for supporting the rolls 6 in parallel on the same plane. A cushion material such as soft urethane foam is used for the roll support plate 7, and its lower surface is attached to the upper surface of the back plate 3, and both end surfaces and both side surfaces are attached to the inner peripheral surface of the frame plate 1, respectively. Fixed. As shown in FIG.
As shown in FIG. 2, a plurality of partition walls 9 are projected at equal intervals, and a roll support groove 10 having a groove width d larger than the diameter r of the roll 6 is formed between the adjacent partition walls 9.

The groove bottom of each roll supporting groove 10 forms a gentle curved surface from the outer peripheral surface of the roll 6, and each partition wall 9 rises with its width narrowing from the base end portion to the tip end portion, and the upper end surface becomes a flat surface. ing. The groove depth h of each roll support groove 10 is set to be smaller than the diameter r of the roll 6, so that the roll 6 supported by the roll support groove 10 projects slightly above the groove opening. In this embodiment, the roll supporting plate 7 is entirely made of a cushion material, but the present invention is not limited to this, and each partition wall 9 may be made of a cushion material.

The roll supporting plate 7 is, if necessary,
As shown in FIG. 5, concave grooves 11 having a rectangular cross-sectional shape are formed on both sides of one roll supporting groove 10, respectively. These recessed grooves 11 are provided at the bent portions of a cushion mat that requires folding, and the roll support plate 7 is bent so that the groove openings of the recessed grooves 11 are closed. Note that each recessed groove 11 may be filled with a super soft cushion material 13.

As shown in FIGS. 6 and 7, each roll 6 has a second roll member 22 slightly shorter than the first roll member 20 inserted into an inner hole 21 of the first roll member 20, It has a structure in which both end openings of the first roll material 20 are closed by end plates 23. The first roll material 20 and each end plate 23 are formed of a cushion material such as soft urethane foam,
Further, the second roll material 22 is formed of a hard cushion material like foam rubber, and when the load of the human body is applied to the roll 6, the first roll material 20 is first compressed and deformed, and then the second roll material 22 is compressed. The second roll material 22 elastically deforms so as to crush the inner hole 24.

The inner diameter of the first roll material 20 and the outer diameter of the second roll material 22 are substantially the same, so that the second roll material 22 is tightly fitted in the inner hole 21 of the first roll material 20. Are combined. Of all the rolls 6, each roll 6 at the central portion of the length corresponding to the waist of the human body has the inner diameter of the second roll material 22 set to be smaller than that of each roll 6 corresponding to the other region, This supports the maximum load on the center of the length, prevents the waist from sinking, and supports the human body in a natural shape.

Further, the lower surfaces of both ends of each roll 6 are adhered to the upper surface of the roll support plate 7, whereby when a load is applied, the rolls 6 are displaced even if the intermediate portion of each roll 6 is displaced. It is designed not to be displaced. Each roll 6 may be adhered not only to the lower surface of both ends but also to the lower surface of the front plate 2 over the entire length. In this case, the front plate 2,
Each roll 6, roll support plate 7, and back plate 3 are integrated, and the front plate 2 is used when the cushion mat is bent.
There is no fear of floating. Further, even with such adhesion, the lower surface of the intermediate portion of each roll 6 can be freely displaced.

When a human body is laid on the cushion mat having the above structure, the load of the human body acts on each roll 6 through the front plate 2. In each roll 6, the first roll material 20 is first compressed and deformed, and then the second roll material 22 is elastically deformed so as to crush the inner hole 24. In this case, since each roll 6 is supported in the roll support groove 10 of the roll support plate 7 with some space, elastic deformation of the roll 6 in the radial direction is allowed, and the cushioning property becomes good, so that it can be used. The person does not feel the hardness. Further, particularly when the human body is laid on the cushion mat or when the person rolls over, the first hard roll material 20 is first compressed and deformed, so that a soft feeling is transmitted to the human body and a comfortable sleeping comfort is obtained.

Further, since the partition wall 9 of the roll support plate 7 is present between the adjacent rolls 6 and 6, the movement of the roll 6 is prevented, and the space between the adjacent rolls 6 and 6 expands more than necessary to form a gap in the human body. I don't feel it. Furthermore, since the lower surfaces of both ends of each roll 6 are adhered to the upper surface of the roll support plate 7, when the load is applied, even if the intermediate portion of each roll 6 is displaced, the roll 6 will not be displaced. . When the roll 6 is elastically deformed to the height of the partition wall 9 of the roll support plate 7, the front plate 2 is supported by the upper end surface of the partition wall 9, so that the partition wall 9 fills the gap between the adjacent rolls 6 and 6 and Don't feel the gap.

As described above, according to the present invention, a core material is constituted by a plurality of rolls made of cushioning material and a roll support plate for supporting the rolls in a parallel state on the same plane. On the upper surface, a plurality of partition walls are projected at equal intervals, and between adjacent partition walls, a roll supporting groove having a groove width larger than the diameter of the roll is formed.When a load acts on each roll, each roll is Since it is easily elastically deformed in the roll supporting groove, the cushioning property is good and the user does not feel the hardness. Further, since the partition wall of the roll support plate exists between the adjacent rolls, the movement of the rolls is prevented, and the interval between the adjacent rolls does not expand more than necessary and the human body does not feel a gap.

According to the second aspect of the present invention, since at least the respective partition walls of the roll support plate are formed by the cushion material, the partition walls fill the gaps between the adjacent rolls, and the human body does not feel the gaps.

According to the third aspect of the present invention, since the concave groove is formed at the bending position of the cushion mat of the roll support plate, the cushion mat can be easily bent at the concave groove position.
