Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a three-layer structure composed of three layers, an upper layer, a middle layer and a lower layer, which can exert useful effects such as an acupressure effect and a manipulative effect by spinal correction. It relates to the improvement of Futon.

[Prior Art] The purpose of the present invention is to provide a supine human body with an acupressure effect, a manipulative effect, etc., and to support the weight with a proper cushioning property and to provide a proper sleeping posture without the body pressure being dispersed to sink the hips and back. There is a futon consisting of a three-layer structure with a unique structure developed as. (Japanese Patent Publication No. 53-8249 and Japanese Utility Model Publication No. 55-9234) This conventional three-layer structure futon has a fine acupressure effect on the body, and the upper layer that slowly envelops the body restores compression. It is made of synthetic resin foam that has strength and has a number of protrusions formed on the upper surface.It also firmly supports the weight of the body in the supine position, gives a correct sleeping posture and adjusts the strain of the spine to exert a manipulative effect. The middle layer is made of synthetic resin foam having a certain degree of hardness against load, and has corrugated irregularities formed on the upper surface and concave portions formed on the lower surface at locations corresponding to the corrugated convex portions on the upper surface. In addition, the lower layer for absorbing external vibration that interferes with sleep is made of elastic synthetic resin foam material with resilience, and the upper layer, middle layer and lower layer are laminated to form a three-layer structure as a whole. You It is made of three-layer structure duvet.

[Problems to be Solved by the Invention] In the conventional three-layer structure futon configured as described above,
The middle layer has a peculiar weight supporting force and a certain elastic force due to the concave portion formed on the lower surface of the middle layer corresponding to the wavy convex portion of the upper surface of the middle layer, but the lower layer is a relatively soft synthetic resin foam. Therefore, it can easily be extended in the horizontal direction.Therefore, especially in the shoulders, the back part and the center of the body where the user's load is most applied and the corresponding buttocks, waist, etc. Such a force is easily applied, and when it is used by a supine person who has a significantly heavy weight, or when it is used by a normal person for a long time, the strength of the material itself deteriorates with time, and the concave portion of the lower surface of the middle layer is horizontal. It spreads to the method, and as a result, the height of the convex part of the upper surface of the middle layer decreases, it is not possible to firmly support the weight of the supine body and to give a correct sleeping posture, so it is demonstrated by adjusting the spine distortion Three-layer structure It is not possible to fully exert the peculiar manipulative effect, and it is unavoidable that the heavy posture such as the buttocks and the back will be excessively depressed, resulting in a sleeping posture that puts a strain on the spine, and a three-layer structure There was a possibility that the characteristics of could not be fully exhibited.

The present invention has been made in order to solve the above-mentioned problems of the conventional three-layer structure futon. It is intended to provide a three-layer structure futon which does not impair the characteristics.

[Means for Solving Problems] A problem with the conventional three-layer structure futon described above is that the upper layer is made of a synthetic resin foam material having a restoring force against compression, and a large number of protrusions are formed on the upper surface thereof. The middle layer is made of synthetic resin foam that has a certain degree of hardness against load, and has wavy irregularities formed on its upper surface and concave portions on the lower surface at locations corresponding to the wavy convex portions on the upper surface. The lower layer is formed by using an elastic synthetic resin foam material having a restoring force as a material, and the upper layer, the middle layer, and the lower layer are laminated to form a three-layer structure as a whole. A cylindrical body made of an elastic synthetic resin material having a bottom plate having an arcuate portion having a shape along the roundness of the inner circumference and having flanges protruding from both ends of the arcuate portion on its bottom surface. The three-layer structure It is characterized in that a plurality of them are accommodated in the recesses on the lower surface of the middle layer of the shoulder part and the back corresponding part of the body, and a plurality of them are housed in the recesses of the middle layer lower part of the three-layer structure futon body corresponding to the central part of the body and the hip buttocks. It is solved by the three-layer futon.

In addition, the three-layer structure futon is folded in three, and multiple cylinders are installed in the recesses on the middle lower surface of the shoulder and back corresponding to the first head of the three-layer structure futon. A three-layer structure futon may be characterized in that a plurality of cylindrical bodies are housed in the recesses of the middle-layer lower surface of the layer-structure futon body corresponding to the central part of the body and the lower back region.

[Operation] Since the three-layered futon according to the present invention has the above-described structure, it sleeps from the original posture of human beings, such as the part from the shoulder to the back and the part from the central part of the body to the waist and hips. Even if it is the most weight-hungry part, the circular arc part of the cylinder is located along the inner peripheral surface of the recess on the lower surface of the middle layer, and the load is distributed and received by the bottom plate with the collar part, so the lower surface of the middle layer It has a function as a reinforcing material for the concave portion, and there is no possibility that the concave portion in the middle layer will spread horizontally in response to the load. Therefore, the height of the corrugated convex portion in the middle layer is always constant even when lying down, and has a collar portion. The bottom plate disperses the pressure from the middle layer to the lower layer due to the action of the collar portion, naturally it is possible to prevent the lower layer itself from sinking and also to prevent the rotation of the cylinder body, which is the original function of the middle layer. Long time It can be maintained over a period of time, and it is possible to semi-permanently and fully exhibit useful effects of the three-layer structure futon, such as acupressure effect and manipulative effect by spinal correction.
