Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cushion body used for beds, sofas, etc.

Traditionally, as cushion bodies for beds, sofas, etc.
Interconnected coil springs are used.

This coil spring has the disadvantage that its cushioning properties deteriorate when used for a long time or under harsh conditions.

In particular, if a defect occurs in a part of the connected coil spring, it is difficult to repair this part.

Furthermore, when used for a long period of time, there was also the drawback that noise (squeak) was generated when the coil spring curved.

The purpose of the present invention is to improve the above-mentioned conventional drawbacks by using a magnetic spring based on the magnetic force of a permanent magnet instead of a coil spring, and also to improve blood circulation in the human body using the magnetic field of the permanent magnet to prevent fatigue. Our objective is to provide cushion bodies for beds, sofas, etc. that can be used as cushions.

The present invention will be explained below based on examples.

FIG. 1 is a top view showing an embodiment of the present invention, in which a mattress 6 is constructed by arranging multiple rows of cushion bodies 5 in the lateral direction, in which cushion elements 1, 2, 3, 4, . . . are connected. This is what I did.

As shown in FIG. 2, the cushion body 5 has a structure in which a plurality of permanent magnets 8a+8b, 8c are mounted in an inner case 1 made of a non-magnetic material such as stainless steel or hard synthetic resin. They are stacked so as to be slidable in the vertical direction via magnetic elastic members 9a, 9b, and 9c.

And a plurality of permanent magnets 8a. 8b, 8c magnetic pole N
, S are formed on the end faces in the vertical direction, and the magnetic poles of the vertically opposing magnets are made to be the same.

Furthermore, the uppermost permanent magnet 8a is made to protrude from the inner case 1 in order to be able to cope with local loads.

A plurality of cushion elements having the above structure are placed in an outer case 10 made of hard synthetic resin or the like to form a cushion body 5.

A cushion cover 11 made of an elastic material such as synthetic resin foam is placed on the top of the outer case 10 so as to cover the uppermost permanent magnet of each cushion element.

A canvas 12 or the like is pasted on the inner surface of the cushion cover 11 so that the end of the uppermost permanent magnet is attached to the cushion cover 1.
Try not to get caught up in 1.

A space 13 is provided between the uppermost permanent magnets, so that the uppermost permanent magnet can better cope with local loads.

A large number of the cushion bodies 5 are laterally arranged as shown in FIG. 1 to form a bed mattress 6, for example, as shown in FIG. 3.

Next, the operation of the present invention will be explained.

When a person lies on the mattress 6 of the bed shown in FIG. 3, the load is absorbed by the permanent magnets 8a of each cushion element.

Join 8bj8c9...etc.

Then, each permanent magnet moves downward and engages the elastic bodies 9a, 9.
b, 9c, etc., but when the distance between the vertically opposing permanent magnets becomes less than a certain value, a repulsive force of magnetic force occurs, resulting in a so-called magnetic spring action.

In areas where a large load is applied to the pinerest 6, the magnetic force of each permanent magnet should be increased, the number of cushion elements per unit area should be increased, and the thickness of the elastic body inserted between each magnet should be increased. The cushioning properties can be improved by, for example, increasing the thickness.

Furthermore, in the present invention, as shown in FIG. 3, when the magnetic poles N and S of the uppermost permanent magnets are made different in each adjacent cushion element, the lines of magnetic force flow inside the cushion cover 11 and its upper part. Start running horizontally and vertically.

These magnetic lines of force have the effect of improving blood circulation in the human body,
It is effective in recovering from fatigue and preventing swelling.

In addition, in this invention, since an elastic material is inserted between the vertical permanent magnets, the cushioning properties due to the magnetic force ζ and the cushioning properties due to this elastic material are added, so the cushioning properties are improved compared to conventional coil springs. can be done.

As described above, the present invention is a cushion body that uses the repulsive force of a permanent magnet instead of a conventional coil spring, so the cushioning properties can be adjusted as desired, and no noise is generated. Since it is unitized, it can be partially repaired, and it provides cushion bodies for beds, sofas, etc. that are good for health.
