Definitions

  • This invention relates to a mattress which provides a sound sleep to a sleeper.
  • the central portion (e.g. shoulder, waist or hip) of the sleeper's body sinks into the bedding.
  • the ideal condition of a mattress be such that it is soft to the touch yet firm enough to uniformly distribute the sleeper's weight.
  • numbereral 1 indicates a mattress of rectangular shape (e.g. 1900mm X 1300mm X 40mm) which is made of semi-hard urethance foam rubber such as Rubbetan F or Rubbetan H (both are trademarks produced by Toyo Rubber Industry Co., Ltd of Japan).
  • This mattress is provided with a number of round protrusions 2 on both upper and lower surfaces thereof and these protrusions 2 form a regular pattern.
  • each protrusion 2 it is preferable that the pitch between the protrusions 2 is about 27 to 35 mm ( 1.06" to 1.38” ) while the height of the protrusion 2 is about 10 mm ( 0.39" ).
  • the mattress of this invention is substantially featured by the provision of a corrugated board of hard material, such as plastic, which is sandwiched between the upper layer and the lower layer of the mattress 1.
  • the corrugated board when a sleeper lies on the mattress, no specific portion of his body (e.g. hip or waist) sinks deep into the mattress Namely, the weight of his body is uniformly distributed over the mattress so that he can have a sound sleep.
  • the corrugated board of this invention can consist of large and small portions which terminate at the area of the mattress where the sleeper's knee bends so that the mattress can be easily folded and transferred to a desired storing place such as a closet.
  • the magnetic force is good for recovering from fatigue or for adjusting the functions of human organs.
  • the magnetic force is said to be effective for "the deficiency syndrome of magnetic fields"such as stiffness in the shoulders, pain in the spinal cord, waist pain, prostration, the habitual habitual headache or the imbalance of the autonomic nerve.
  • the mattress of this invention is further provided with a desired number of magnets.
  • a desired number of magnets 3 are disposed. They are substantially distributed at the portions of the mattress which come into direct contact with the sleeper (e.g. shoulder, spinal cord, waist or hip).
  • the sleeper e.g. shoulder, spinal cord, waist or hip.
  • the magnets having the following particulars have shown a favorable effect. thickness: about 3mm (0.12") diameter: about 11.5mm (0.45”) magnetic flux density: 500-600 gauss
  • the magnets 4 are mounted in such a way that a slight gap remains between the sleeper's body and the magnets when the sleeper lies on the mattress of this invention.
  • a cloth which can favorably disperse aweat or the like encloses the mattress 1 for.providing the softer feeling to the mattress 1.
  • Two beddings were prepared.
  • FIG.5 shows the mean body pressure change chart obtained by the Manschette method, wherein the weight of the respective portions of the subject is converted into the Manschette's inner pressure, which can be measured as body pressure.
  • the mean weight of the subjects who slept on the conventional mattress is described by a solid line, while the mean weight of the subjects who slept on the mattress of this invention is described by a dotted line.
  • the conventional mattress shows high body pressure of about 20 to 25 kg (44.15 to 55.19 1b) at the waist or the hip. This implies that the above portions of the body considerably sink into the mattress.
  • the mattress of this invention shows a body pressure of about 5 to 10kg (11.04 to 22.08 1b) at the head and legs and almost uniform body pressure of about ' 15kg (33.11 1b) at the shoulder, the spinal cord and the waist.
  • FIG. 6A and FIG. 6B provide other charts showing the length and width distribution of the body pressure measured by Manschtte method wherein FIG. 6A relates to pressure distribution of the mattress of this invention while FIG. 6B relates to the pressure distribution of the conventional mattress.
  • the conventional mattress shows that the body pressure substantially concentrates on the area ranging from the waist to the hip, and this area extends in both right and left directions from the spinal cord.
  • the mattress of this invention shows that the body pressure is uniformly distributed over the shoulder, the spinal cord,the waist and the leg portions and no portion of the body is subject to the concentration of body pressure.
  • the wide contact area which can be observed when the subject lies on the conventional mattress, also provides a shallow sleep since the humidity or temperature of the contact area rises.
  • the user since it provides a uniform distribution of weight, the user can have a deep and sound sleep.
