A sleeping mattress

BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The present invention is concerned with a sleeping mattress, particularly a magnetic sleeping mattress having magnetic curing effect.

DESCRIPTION OF THE PRIOR ART

Sleeping is indispensably important to the human being. It is necessary for deep and sweet sleep to assume right posture during lying on a mattress, that is, to stretch the back bone so that the organs of the human body are made relaxed. Illness is not a few which is caused in curved back bones. In this regard, existing mattresses do not pay attention to keeping the back bone balanced and smoothly circulating the blood for removing stiffness in the shoulders or tiredness. Therefore, ideal sleeping posture could not be kept.

SUMMARY OF THE INVENTION

A main object of the invention is to provide a sleeping mattress by which the back bone is kept straight during sleeping, and the blood is smoothly circulated due to its magnetic effect to remove the stiffness in the shoulders or fatigue.

Another object of the invention is to provide a sleeping mattress which is excellent in the air permeability, thereby to make cool in the summer and warm in the winter.

A further object of the invention is to provide a sleeping mattress which is well conditioned in the magnetic curing effect.

A still further object of the invention is to provide a sleeping mattress which is moderate in hardness balancing as a whole, and holds its shape.

Other objects and advantages to be brought about by the invention will be apparent from description of the invention with reference to the attached drawings.

DETAILED DESCRIPTION OF THE INVENTION

A mattress according to the invention comprises a structure of four layers in which a first layer 1 is a wave layer, a second layer 2 is a magnetic layer including magnets, a third layer 3 is a compression palm lock layer, and a fourth layer 4 is a cushion layer.

The first layer 1 is for balancing the body weight in uniform dispersion and giving soft massaging effect to the body. This layer comprises a cushion material of about 2cm in thickness, preferably a urethane form 5 is formed thereon with a thin outer cover 6 and is perforated with holes regularly lengthwise and crosswise, in which the urethane form 5 is provided with a plurality of wave like convexes regularly lengthwise and crosswise, and the thin outer cover 6 is impregnated with resin liquid such as urethane form. Concerning the number of the holes, about 21 x 12 are required for the size of the product being 1950 (length)mm x 930 (width)mm, and about 21 x 20 are required for 1950 x 1300. Permanent magnets as later mentioned are exposed at the holes 7.

The second layer 2 is for naturally straightening the spine while giving the magnetic effect to the body. In this layer, the thin sheet 8 made of urethane form is arranged thereon with semi-circle projections 9 in parallel, and desired ones of the projections 9 are laid with ferrite permanent magnets 10. The second layer 2 is, as later mentioned, made integral with a third layer 3 via hard grains 11 of urethane resin and adhesives so that it holds the shape of the mattress.

For a permanent magnet 10, used is one which is two poles at one side (magnetism on one side). Thereby, magnetic line of force reaches far (see Fig.5B) in comparison with the conventional one (see Fig.5A). Thus, the magnetic effect serves at deeper parts of the human body so that the blood runs actively and the stiffness is removed from the body. In order to provide the magnetic curing effect to the maximum, it is preferable to deposit the permanent magnets 10 having 850 gauss at parts nearest to the human body, that is, at the projections 9. However, the magnets 10 are covered with thin sponge or cloth for preventing unpleasant feeling caused by directly touching the skin. The magnets 10 are not necessarily all arranged within the projections 9, but gathered at the parts corresponding to the shoulders, back, waiste or legs. Fig. 4 illustrates an example of such an arrangement with black marks.

The third layer 3 is for maintaining moderate hardness over the entire mattress in order to prevent the spine from curving due to unnatural sinking of the body. This layer comprises compressed fibers such as palm or the like, and is arranged with reinforcing material, for example, steel wires 12-of around 3mm in diameter thereover with appropriate space for providing stronger rigidity. For a three-fold type, the steel lines 12 are arranged in division lengthwise. For a non-folding type, the steel wire 12 may be divided appropriately. Further, plastic plate may be used as the reinforcing material, instead of the steel wire 12. The third layer 3 integrally holds grains 11 of hard urethane resin and binding agent between the second layer 2 and itself and forms many concaves and convexes, and the concaves fit within the projections 9, which concaves have nature of holding shape. In such a manner, the semi-circular shape of the projections 9 is firmly kept and prevented from depression.

The fourth layer 4 is for supporting as a whole the mattress, effecting moderate cushion and softening vibration of the body. This layer is in general made of urethane form.

The mattress composed of the four layers may be three-fold or non-folding type. In use, the mattress is protected with a cover 13.

Effects brought about by the four layered structure as follows.

• 1) By wave-like projections of the first layer and projections 9 of the second layer, the body weight is dispersed in balance while soft massaging effect is obtained. Through the projections and the compressed palm layer of the third layer, evaporation of the moisture by such as sweat and others is accelerated, so that ideal feeling may be effected as being warm in the winter and cool in the summer.
• 2) The magnets arranged in the second layer act on the human body as follows.

  • A. Effecting magnetism to the human body
  • B. Inviting new electricity
  • C. Generating electric current in the blood
  • D. Increasing ion in the blood
  • E. Changing action of autonomic nerve
  • F. Smoothening circulation of the blood
  • G. Improving stiffness or ill conditions

• 3) Grains of hard urethane resin between the second and third layers, and the third layer including the reinforcing material give moderate rigidity over the mattress, and the back bone is kept in straight during lying on the mattress.
• 4) The lowest urethane form layer gives comfortable cushion feeling.
