Abstract

PROBLEM TO BE SOLVED: To take a preferable sleeping posture without any burden on the backbone, prevent the occurrence of a bedsore, and maintain high comfort and enough gas permeability by forming granular resin materials to have a movable spherical or elliptical shape for forming a support plane well fit to the body of a person lying thereon. SOLUTION: A cover cloth 1a is filled with elastic granular resin material 3. In this case, the granular resin material 3 may be hollow ball type or solid ball or elliptical body type, or the ball or elliptical ball body may be made of expanded resin, using material such as expanded styrene, expanded neopolyprene, and expanded urethane. Also, the expanded resin is available in the form of continuous expanded or independently expanded type. When a person lies on a mattress 1, the granular resin material 3 shows mobility for moving from a strong body pressure position to a low body pressure position, depending on the irregularities of a body, within mattress internal space separated with a partition 4 and limited with connecting parts 5, thereby providing a support plane 8 fit to the body at suitable elasticity, and dispersing and bearing body pressure almost homogeneously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedding used for sleeping and recuperating a person, and more particularly to a mat used as a bedding placed on a floor or a tatami mat.

[0002]

2. Description of the Related Art Conventionally, as a bedding, a mattress in which a bag-like surface material is filled with cotton, wool, or the like has been widely used.

[0003] By the way, the required functions are different between the bedclothes and the bedding. In the case of bedding, lightness and softness are required to make it easy to turn over, but in the case of bed bedding, on the other hand, hardness that can maintain an appropriate sleeping posture is required.

However, many of the above-mentioned beddings such as cotton duvets are relatively soft, and when a person sleeps thereon, the body sinks with its weight, the body bends in a W shape, and the spine bends. It is difficult to maintain a sleeping posture. The weight of each part of the body is 44% for the waist, 33% for the chest, 15% for the lower legs, and 18% for the head. Because the condition continues, it is difficult to get tired. In addition, it is difficult to turn over, so that not only is it difficult to sleep, but also the spine bends at the lower back, causing back pain. Therefore, in order to solve this problem, mats or the like in which relatively hard padding or springs are connected and built in are often used for health. In addition, some water beds have been used to reduce the number of times of turning over, because water is used to support the weight with a uniform pressure, absorb the unevenness of the body, and do not obstruct the blood flow.

[0005]

However, in the above-mentioned hard beddings, although it is possible to prevent a partial fall of the waist and the like, it is uncomfortable and often turns over. As a result, the person falls asleep and cannot sleep deeply. In addition, even when turning over, bedsores are likely to occur in portions where pressure and stuffiness are frequent. This is even more so for bedridden sick people.

[0006] In addition, a water bed can prevent a part of the body from falling by supporting the weight with a uniform pressure by the water acting as a spring. However, since the air permeability is poor, the water bed is used for a part where the bedding is in close contact with the body for a long time. There is a problem of bedsores, and it is not particularly suitable as a treatment mat for sick people.

[0007] The cause of bedsores is that the body pressure is applied to one location to cause congestion, and that bacteria grow on the body surface due to stuffiness. In other words, conventional bedding such as futons and mats do not disperse body pressure and have poor ventilation, which causes bedsores, so these points are also eliminated, and mats that can contribute to sleep and health promotion of healthy people Is desired.

The inventor of the present invention has continued to study while filling the mat with various materials and repeating bedtime experiments. As a result, the specific material can exert appropriate mobility to support the body in a correct sleeping posture. It was found that the required air permeability was also satisfied.

Accordingly, an object of the present invention is to provide a comfortable and highly breathable mat which maintains a preferable sleeping posture without burdening the spine and does not cause bedsores based on the above findings.

[0010]

According to the present invention, there is provided a mat filled with a particulate resin material having elasticity, wherein the particulate resin material is used when a person lies on the mat. It is characterized by being formed in a spherical or elliptical shape that moves so as to create a support surface that fits the body.

[0011] Further, at least at one or more locations in one direction, there is provided a partition for dividing the filled particulate resin material, and a connecting portion between the front and back for restricting the movement of the filled particulate resin material. Is preferred.

The particulate resin material is preferably a foamed resin such as styrene foam or neoprene foam.

According to the present invention, when a person sleeps on the mat, the elastic particulate resin material filled in the mat is subjected to the high body pressure received in accordance with the unevenness of the body due to its morphological characteristics. The support surface that fits the body with fluidity that escapes to weak places is made with appropriate elasticity, and body pressure can be distributed almost uniformly like a water mat, so it can be received even with protruding parts of the body It can prevent congestion due to pressure and can support the body softly in a proper sleeping posture, so it can contribute to comfortable sleep and medical treatment without burdening the spine, It can be prevented that bending causes back pain. In addition, the particulate resin material forms a gap between each other due to its morphological characteristics, has good air permeability, and can prevent the body from becoming stuffy, causing bacteria to grow and causing floor displacement.

If a partition for dividing the filled particulate resin material is provided at one or more locations in at least one direction, it is possible to prevent the particulate resin material from being extremely deviated by use. The partition for dividing can be replaced by a connecting portion between the front and back which restricts the movement of the filled particulate resin material, or the both may be combined to prevent the displacement of the particulate resin material. In addition, the partition can be used as a folding portion for storing a mat. For example, if the partition is provided at two locations in the longitudinal direction evenly and in opposite directions, it can be folded in three and can be easily handled.

If the particulate resin material is a foamed resin such as foamed polystyrene or foamed neoprene, the air permeability is not impaired as a whole by retaining air between the foamed particles in the particles or in the foamed particles, and the heat insulating property and the heat insulating property are maintained. The mat can be rich.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view showing a state in which a mat 1 of the present invention is spread on a floor 2 such as a tatami mat and a person is sleeping thereon. FIG. 2 is a plan view showing the entire mat 1. It is a figure and a vertical side view. The mat 1 may be laid on a mattress, a bed spring mattress, or the like.
An open coil type spring in which hard coil springs are connected vertically and horizontally to easily disperse body pressure is preferable.

The mat 1 has a general rectangular shape as a bedclothes, has a thickness of about 4 cm to 5 cm when flattened, and has a thick and durable cotton cover cloth 1 a in an elastic particulate resin material. 3 are filled. Particulate resin material 3
Is considered to be a hollow ball, a solid sphere or an ellipsoid, and a sphere or an ellipsoid of a foamed resin made of styrene foam, neopropylene foam, urethane foam resin, or the like. The foamed resin includes continuous foaming and closed foaming. In the present embodiment, the particulate resin material 3 is made of a foamed resin. The diameter of each of these is 2mm
5 mm to 6 mm is most preferable within the range of ８8 mm.
The particulate resin material 3 forms a gap between each other due to its morphological characteristics, has good air permeability, and enhances the air permeability of the mat 1. In addition, if the particles have air in the particles (foamed resin or hollow particles), they do not impair the air permeability and are excellent in heat retention and heat insulation, so that they are good as a bedclothes. In consideration of this, a foamed resin of independent foaming is most preferable as the particulate resin material 3.

The mat 1 is provided with two partitions 4 evenly in the longitudinal direction. By this partition 4,
The particulate resin material 3 filled in the mat 1 is divided.
One of the partitions 4 is connected to the cover cloth 1 a on the front side of the mat 1, and the other is connected to the back side of the mat 1.
The partition 4 is provided in order to prevent the particulate resin material 3 from being extremely deviated by use, but if this portion is used as a folded portion of the mat 1, it is folded into three to reduce the size to one third. It can also be stored at the end, making it convenient to handle.

As shown in FIG. 2A, the mat 1 is provided with a connecting portion 5 between the front and back sides at a total of six places at three places in the width direction in one partition. The connecting portion 5 connects the front cloth and the back cloth of the cover cloth 1a by sewing with a 20th-count cotton thread at a stitch pitch shorter than the diameter of the particulate resin material 3. The sewing direction of the connecting portion 5 is a width direction perpendicular to the length direction A in which the particulate resin material 3 moves, and the movement of the particulate resin material 3 prevents the particles from being extremely shifted in the mat 1. Can be. The connecting portion 5 may be formed by sewing with a thread, or by bridging a front cloth and a back cloth with an intermediate cloth.

The particulate resin material 3 in the mat 1 is shown in FIG.
(B) As shown in FIGS. 4 and 5, the mat 1 is filled from a fastener portion 6 provided on one side surface. The fastener portion 6 includes two first fasteners 6a in the horizontal direction and second fasteners 6b in the vertical direction. The first fastener 6a is attached to the cover cloth 1a, and the second fastener 6b is attached to the backing cloth 1b sewn on the back side of the cover cloth 1a. By providing these two types of fasteners which are orthogonal to each other, each restricts the spread in the vertical and horizontal directions, and prevents the fasteners from being disengaged by the pressure when a person lies on the mat 1. Can be. In addition, the granular resin material 3 is individually filled with a thin bag material, and the cover cloth 1a divided by the partition 4 is
Each of the three bag materials can be accommodated.

Thus, as shown in FIG. 1, when a person sleeps on the mat 1 of the present embodiment, the particulate resin material 3 is separated by the partition 4 and in the space inside the mat limited by the connecting portion 5. In accordance with the unevenness of the body, the support surface 8 that fits the body by exhibiting fluidity that escapes from a place with strong body pressure to a place with weak body pressure with appropriate elasticity, and receives the body pressure almost uniformly dispersed As a result, it is possible to prevent congestion due to pressure on the protruding parts such as the waist 7 and to support the body softly in an appropriate sleeping posture, contributing to comfortable sleep and medical treatment without burdening the spine Can prevent the spine from bending and causing back pain. In addition, the air permeability of the mat 1 is improved by the air permeability due to the morphological characteristics of the particulate resin material 3 as described above, so that it is possible to prevent the body from becoming stuffy and bacteria from growing and causing floor displacement. In addition, the foamed resin particles rub against each other due to the movement of the particulate resin material 3, and the positive and negative electrode electrodes 0.001 to 0.5 k
v static electricity is generated. It has been known from the use experiments of the test subjects that the weak static electricity has a therapeutic effect on the human body. That is, when the mat of the present embodiment was used, muscle pain was improved several days later, and a decrease in subcutaneous fat due to sweating was observed. As described above, the mat of the present embodiment can provide an optimal mat as a medical treatment mat for preventing floor displacement and a health promotion mat.

The present invention can be configured in various modes in addition to the embodiments described above. For example, in the present embodiment, both the partition 4 and the connecting portion 5 are provided in combination,
Both are not essential, and the partition 4 or the connecting portion 5 alone can also function to prevent the deviation of the particulate resin material 3.
