FIELD OF THE INVENTION The present invention relates to a mattress.

[0002]

2. Description of the Related Art As a conventional technique of this kind, there is an actual method 62
The one disclosed in Japanese Patent Laid-Open No. 53067 is known,
In the mattress disclosed in this publication, a plurality of flexible pipes are vertically penetrated through urethane. The flexible pipe ensures air permeability in the mattress.

[0003]

Generally, mattresses are
The mainstream is a spring mattress in which urethane and a spring are combined, but it is necessary to separate the urethane and the spring at the time of disposal, and it is troublesome to dispose of the spring. For this reason, a mattress composed only of urethane is used without using a spring as in the above-mentioned conventional technique, and the urethane has a through hole for providing air permeability. However, in order to obtain an ideal sleeping posture with a mattress, it is preferable that the mattress has a cushioning property such that the buttocks are appropriately depressed when in the supine position, but the restoring force of a mattress in which a spring is not used is small, and In the above-mentioned conventional technique, since the flexible pipe is provided on the entire mattress, the hip portion also falls at the same time as the buttocks fall. Therefore, a comfortable sleeping posture cannot be obtained.

It is an object of the present invention to provide a urethane mattress that provides an ideal sleeping posture.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the measures taken in the invention of claim 1 are, in a mattress made of urethane, a through hole is formed in a direction perpendicular to the urethane and the buttocks of a human body. That is, the number of through-holes in the area hitting the body is made dense and the number of through-holes in the area hitting the waist of the human body is made small.

In order to solve the above-mentioned problems, the measures taken in the invention of claim 2 are, in a mattress made of urethane, a through hole formed at a portion where the through hole is formed in the vertical direction of the urethane and the buttocks of the human body hit. The diameter of is larger than the diameter of the surrounding through holes, and the diameter of the through hole in the region where the waist of the human body hits is smaller than the diameter of the surrounding through holes.

[0007]

According to the above-mentioned means of the present invention, the through holes are formed in the vertical direction of the urethane, and the through holes of the part where the buttocks of the human body hit the urethane are denser than the number of surrounding through holes. Since the urethane that hits the buttocks is reduced in resilience and becomes softer than the surrounding urethane, the depression of the buttocks of the human body is large, and the through holes in the area where the waist of the human body hits is greater than the number of surrounding through holes. Since it is formed to be sparse, the resilience of the urethane hitting the waist does not change in particular and is harder than the surrounding urethane, so the waist of the human body is less likely to fall. Moreover, since the shoulders of the human body are appropriately depressed, it is possible to obtain a comfortable sleeping posture with the urethane mattress.

According to the above-mentioned means of claim 2, the through hole is formed in the urethane in the vertical direction, and the diameter of the through hole of the portion of the urethane that touches the buttocks of the human body is made larger than the diameter of the surrounding through holes. By doing so, the restoring force of the urethane that hits the buttocks becomes weaker and becomes softer than the surrounding urethane, so the depression of the buttocks of the human body is large, and the diameter of the through hole in the area where the waist of the human body hits is larger than the diameter of the surrounding through holes. Since it is made small, the resilience of the urethane that hits the waist does not change and it is harder than the surrounding urethane, so the waist of the human body is less likely to fall. Moreover, since the shoulders of the human body are appropriately depressed, it is possible to obtain a comfortable sleeping posture with the urethane mattress.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a plan view of a urethane mattress. As shown in the figure, the mattress 10 includes a cushion body 11 made of urethane, a hard cushion body 12 adhered to a lower surface of the cushion body 11, and a cushion body 1.
1 is formed of an exterior body (not shown). Further, the exterior body (not shown) is composed of a seal made of polyester fiber, and an edge tape made of polyester fiber similarly for sewing the edges of the upper and lower sheets. The upper cushion 1 is on the upper surface of the mattress 10.
4 is provided, and the sheets are used by being covered on the upper cushion 14.

Next, the cushion body 11 which is a feature of the present invention
Will be described. FIG. 2 shows a side view of the mattress 10 showing an ideal sleeping posture. It is assumed that the left side of the cushion body is where the head of the human body is located. As shown in the figure, the cushion body 11 is a head cushion body 11
a, buttocks cushion body 11b and leg cushion body 11
c is divided into three parts, and a through hole 13 is formed in the vertical direction in each cushion body. Further, a through hole 13 is similarly formed in the hard cushion body 12 to ensure air permeability. A through hole is formed in a portion of the head cushion body 11a where the shoulder portion of the human body hits is denser than the number of through holes formed in the portion where the neck portion and the waist portion hit. Further, the leg cushion body 11c is formed so as to be symmetrical to the head cushion body 11a, and the head cushion body 11a and the leg cushion body 11c can be interchanged. The through holes 13 formed in the buttocks cushion body 11b are formed so as to be denser than the number of through holes formed in the shoulder portion. From this fact, due to the number of through holes 13 formed in the cushion body 11, the through holes 13 are sparsely distributed in the region formed in the cushion body 11.
The restoring force of the cushion body 11 itself does not decrease so much, and the depression due to the weight of the human body is small. In addition, in the portion where the through holes 13 are densely formed, the cushion body 11 is formed.
The restoring force of itself is inferior to that of the cushion body formed so that the through holes 13 are sparse, and the depression also appears appropriately depending on the weight of the human body. Although the diameter of the through holes formed in each cushion body is the same in the first embodiment, the diameter is not limited to this, and the diameter of the densely formed through holes 13 can be increased. It is also possible to do it.

As described above, since the through holes 13 are formed in accordance with the respective parts of the human body, the buttocks are appropriately depressed in the buttocks cushion body 11b formed so that the through holes 13 are densest. The waist portion formed so that the through-holes 13 are sparse does not have much depression, and other shoulder portions, legs, etc. also have an appropriate depression (not as much as the buttocks). From this, as shown in FIG. 2, an ideal sleeping posture can be obtained by the urethane mattress.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 3 shows a plan view of the urethane mattress. As shown in the figure, since the mattress 20 has the same structure as the mattress 10 shown in the first embodiment, the description of the parts using the same reference numerals is omitted.

Next, the cushion body 21 which is a feature of the present invention
Will be described. FIG. 4 shows a side view of the mattress 20 showing an ideal sleeping posture. Note that the left side of the cushion body will be described assuming that the head of the human body is located. As shown in the figure, the cushion body 21 is a head cushion body 21.
a, buttocks cushion body 21b and leg cushion body 21
c is divided into three parts, and a through hole 22 is formed in each cushion body. A through hole having a diameter larger than a diameter of a through hole formed in a portion where the shoulder portion of the head cushion body 21a hits the human body is formed. The leg cushion body 21c is formed symmetrically with the head cushion body 21a.
The head cushion body 21a and the leg cushion body 21c can be exchanged. Buttocks cushion body 21
The through hole 22 formed in b is formed to have a diameter larger than that of the through hole formed in the shoulder portion. From this, the reduction of the restoring force of the cushion body 21 itself is small in the region where the diameter of the through hole 22 is small due to the size of the through hole 22 formed in the cushion body 21,
In addition, there is little decrease due to the weight of the human body. Also, through hole 2
In the portion where the diameter of 2 is large, the cushion body 21
The resilience of itself is inferior to that of the cushion body in which the diameter of the through hole 22 is formed small, and a proper depression also appears depending on the weight of the human body.

As described above, since the through holes 22 are formed in accordance with the respective parts of the human body, the buttocks of the buttocks cushion body 21b in which the diameter of the through holes 22 is large are appropriately depressed so that the buttocks are appropriately depressed. The waist is formed with a small diameter, and there is little fall, and other shoulders, legs, etc. fall moderately (not as much as the buttocks).
From this, as shown in FIG. 4, the urethane mattress can obtain an ideal sleeping posture.

Since the mattresses used in the above-mentioned first and second embodiments are made of urethane, when the mattresses are discarded, they can be discarded separately and the urethane can be recycled.

[0018]

According to the above-mentioned mattress of claim 1, the through holes are formed in the urethane in the vertical direction, and the through holes of the portion of the urethane where the buttocks of the human body hit are denser than the number of surrounding through holes. Since the urethane that hits the buttocks is reduced in resilience and becomes softer than the urethane around it, the gluteal depression of the human body is large, and the through holes in the area where the waist of the human body hits the surrounding through holes. Since it is formed to be sparser than the number, the restoring force of the urethane hitting the lower back does not change in particular and becomes harder than the surrounding urethane, so the lower back of the human body is less depressed. Moreover, since the shoulders of the human body are appropriately depressed, it is possible to obtain a comfortable sleeping posture with the urethane mattress.

According to the above-mentioned mattress of claim 2,
The urethane has vertical through-holes, and the diameter of the through-hole in the area of the human body where the buttocks hit is larger than the diameter of the surrounding through-holes, which reduces the restoring force of the urethane hitting the buttocks. However, since it becomes softer than the surrounding urethane, the buttock of the human body is largely depressed, and the diameter of the through hole in the area where the waist of the human body hits is smaller than the diameter of the surrounding through holes, so the restoring force of the urethane hitting the waist Since it does not change and is harder than the surrounding urethane, the waist of the human body is less likely to fall. Moreover, since the shoulders of the human body are appropriately depressed, it is possible to obtain a comfortable sleeping posture with the urethane mattress.
