Description

Yo, pillow, bed mat and cushion {BEDCLOTHES, PILLOW, BED MATTRESS AND CUSHION}

The present invention relates to yaw, pillow, bed mat and cushion.

Background Art [0002] Conventionally, a yaw is a representative bedding which can take a comfortable sleep of a Japanese person integrally with a covering blanket, and a yaw, a pillow, a bed mat or a cushion used for sleeping or resting in the present situation are outlined as follows.

1) The pressure per unit area of the contact surface can be reduced by smoothing the hardness of the contact area between the body and the yaw at the upper left position or the sleeping position and receiving the body pressure in a large area. It is generally designed to avoid pressure. Low-elasticity pillows or low-elasticity duvets are typical examples.

2) Cushioning and cushioning with less movement of the body were considered desirable.

Among these, the proposal of the multilayer mattress which reduces the concentration of the body pressure at bedtime, and feels little pressure during bedtime is known (for example, refer patent document 1).

[Patent Document 1] Japanese Unexamined Patent Publication No. 2005-160601

However, in the past studies, there are no ideal postures that can be maintained for a long time, and when the user continues to sleep or rests for several hours or more continuously, pressure or tension is generated at specific sites and muscles, and circulation disorders and muscle fatigue occur. It is a cause of onset, such as pressure sores due to pain in the back of the back and circulatory disorders.

Thus, the present invention is to provide and develop a cushion with less fatigue in the yaw, pillow, bed mat, seating state that can ensure a comfortable sleep and wake.

As a means for solving the problem according to the present invention, the urine, the pillow, the bed mat and the cushion are composed of a plurality of layers, and the body stiffness due to the circulatory disorder caused by the fixed posture by promoting the body shaking at bedtime It provides a cushion with less fatigue even when maintaining postures, pillows, bed mats and seating positions for long periods of time to prevent pain, bedsores.

According to the present invention, a urethane, a pillow, a bed mat and a cushion are formed in a plurality of layers, and a high repulsive surface material having a body pressure dispersion layer is formed on the surface thereof, and a rigid and lightweight body separated from the upper and lower layers in the next layer. We form phosphorus board material and body and head do not sink down during bedtime. In addition, since the intermediate board material is a rigid body, the so-called hammock phenomenon caused by the conventional cushion, that is, the cushion is bent due to the weight, the hammock state (low valley state) to solve the difficulty of moving the body, In coordination with the elastic action of the bottom elastic member, in the case of turning in the transverse direction, the board is inclined toward the inverting body along with the weight movement in the transverse direction, thus acting as a seesaw, thereby facilitating the reversal. The body can be flipped over, it is easy to remove fatigue, and can not be flipped down, and when settled down, water that occupies 70% of the human body does not settle on the floor, and there is no cause of pressure sores.

In addition, the present invention uses a natural rubber foam material [low allergic latex (tannic acid latex)] for the material of the surface material 1 made of a high resilience elastic body and the floor material 3 made of a high resilience elastic body. Unlike synthetic rubbers, natural rubber does not use proteins that cause allergies, and therefore has the effect that even people with allergic symptoms can be used with confidence.

In addition, the cross section of the board member 2 is formed in an arc shape in which the upper portion of the center portion is expanded, and the body is laid down at the center portion thereof, whereby the board member 2 is horizontal and sinks as in the prior art by the weight of the body. It is possible to easily flip the body, and can simply flip the body, thereby preventing the body's water from flowing toward the floor.

In addition, the board member 2 is a board of three divisions in which the waist part, the head part, and the foot part are located, and the repulsion force of each part is made larger, and the board member 2 of the head part is made larger. By changing the board material 2 of the foot to a moderate degree and making it small, these board | substrates of these three divisions can have a very beneficial effect, such as being able to keep level in all directions.

Hereinafter, about preferable embodiment of this invention, in a urine, a pillow, a bed mat, and a cushion, it forms in the multilayer structure of 3-5 layers, and a surface material and a bottom surface material are formed in a body pressure dispersion layer, and these surface materials and The intermediate layer of the flooring material consists of a urine, a pillow, a bed mat, and a cushion formed by forming an elastic body layer through a rigid and lightweight material having less warpage. Further, in order to promote the lateral twisting, a bank-shaped incline for preventing fall is formed at the edges of the transverse side of the surface layer of the yaw, pillow, bed mat or cushion. Further, in the lowermost elastic layer, convex or hemispherical irregularities are formed in the upper surface direction so that the inclination and swinging of the board become easy, the body swings, and the backing is easy.

Furthermore, by forming an air layer between the surface layer and the board layer, the air pressure is lowered at the start of bedtime, the cushioning property is increased, the body pressure dispersion is increased, and it is easy to fall asleep, and the air pressure is gradually increased from about 30 minutes after bedtime to make the high resilience. The structure prevents the sinking of the body and facilitates rocking or torsion. The air pressure can be adjusted by providing a timer to the pump so that the time can be appropriately adjusted according to the sleeping tendency of the individual. Alternatively, an acceleration sensor may be provided on the yaw or pillow to determine that the body movement has become small for a certain period of time, and the air pressure may be gradually increased. For these reasons, about 30 minutes before falling asleep, it is easy to fall asleep to increase body pressure dispersibility, and if it exceeds 30 minutes after falling asleep, the structure which promotes movement of the body is comfortable in the blood circulation of the body Because you can keep.

Example

Next, the yaw, the pillow, the bed mat and the cushion having a three-layer structure which is one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the body pressure dispersibility in the yaw, the pillow, the bed mat and the cushion is shown. And a surface material 1 made of a high-elasticity elastic body and a bottom face material 3 made of a high-elasticity elastic body similarly to the surface material 1, and are formed between the surface material 1 and the bottom face material 3, It is composed of a yaw, a pillow, a bed mat and a cushion, which are formed by forming a rigid board member 2.

First, the surface material 1 which has a body pressure dispersibility and consists of a highly resilient elastic body uses latex as a raw material, and the thickness of the surface material 1 is about 2 cm. Here, in order to increase the softness of the outermost surface layer, the upper layer may be a softer layer, the second layer may be a high repulsion, and the surface material 1 may have a two-layer structure.

The conventional latex material may cause rubber allergy, and in order to prevent this, a low allergic latex (tannic acid latex) is preferably used.

In addition, the bottom face material 3 located on the bottom face is made of latex as a surface material 1, and the thickness is about 5 cm. What is necessary is just to select hardness suitably among them by changing foaming magnification into three types of 15 times, 20 times, and 30 times.

The latex which is a material of the surface material 1 and the bottom face material 3 is all made of a foam material of natural rubber, and its durability is 10 years and is biodegradable in 6 to 7 years. In addition, the synthetic latex has a long life when it is considered to deteriorate in two to three years. In addition, latex is a term which refers to the raw material of raw rubber, and is called latex also when it is a raw material of synthetic rubber.

In addition, the material of the board | substrate 2 is a high functional resin called PS / PE copolymer resin "Pioceran" (brand: Sekisui Chemicals, Inc.), and is excellent in high shock absorption, high rigidity, etc., Furthermore, it recycles As a board | substrate material which consists of possible foams, what changed foaming magnification can be used in order to adjust hardness and lightness.

As shown in FIG. 2, the board member 2 is made of expanded polystyrene, and forms a plurality of through holes 2a, thereby forming air permeability to allow airflow between the surface member 1 and the bottom face member 3. It is possible to form, and by forming the some through-hole 2a, the frictional force of the surface material 1 and the bottom surface material 3 is ensured, and these ashes can be prevented from shifting, and the above-mentioned also As described above, the board member 2 is light in weight, and the hardness can be adjusted by changing the magnification.

Although the present invention has a three-layer structure, four or five layers may be used, and in the use state of the present invention, the urine, the pillow, the bed mat, and the cushion are in a state where the human body X is stopped at bedtime. In Fig. 3 (a), the human body X moves as shown in Fig. 3 (b) when the body X moves backwards or backwards.

Here, in order to promote the lateral twisting, a modification such as forming a weir-shaped inclination for preventing falling off may be considered near the horizontal direction of the surface layer 1 of the urine, pillow, bed mat or cushion [ 4.

In the lowermost elastic layer 3, it is also possible to consider the case where convex or hemispherical irregularities are formed in the upper surface direction so that the inclination and swing of the board 2 become easier, and the body swings easily. 4.

Moreover, as an active means structure, as shown in FIG. 4, the air layer 4 is formed between the surface layer 1 and the board layer 2, the air pressure is reduced at the time of bed start, and cushioning property is favorable and body pressure dispersibility When it is easy to enter by raising the pressure, the air pressure is gradually increased to high repulsion from 30 minutes after going to bed to prevent the body from sinking during bedtime, thereby making it easy to swing or fall back. There is. It is assumed that the air pressure is adjusted by providing a timer to the pump so that the time can be adjusted appropriately according to the personal orientation. Alternatively, a plurality of commercially available acceleration sensors may be provided in the center of the yaw to determine when the body movement is reduced for a predetermined time (about 5 minutes) at the time of elevation, and the air pressure may be gradually increased from this point of time. The reason is based on the experimental result that about 30 minutes from bedtime to elevation will be easier to raise body pressure dispersibility. After elevation, it is the structure that raises the air pressure to reduce the body sinking, and promotes the movement and movement of the body, and promotes blood circulation of the body, avoiding concentration of the pressure to a certain part of the body, and prevents bedsores This is because it is possible to maintain a comfortable sleep and ensure a pleasant wake up and sleep.

Next, the inventors of the present invention conducted a four-day night sleep experiment for 12 healthy subjects using three types of duvets in a random order and adding one additional day.

As three types of duvets, the present invention (called a development duvet), a duvet with a board removed from the present invention (a duvet without a board), and a standard duvet (a rather hard duvet using chemical fibers) were used.

Using these futons, they are allowed to sleep for 7 hours at night, subject to subjective fatigue by Borg's 10-point method before bedtime and during waking up, systemic fatigue (see Table 1), and stiff neck pain (see Table 2). ) And stiff pain in the lower back (see Table 3) to compare changes before and after bedtime.

In this case, a Borg index of 0 is defined as no symptoms at all, and 10 is defined as the condition with the strongest symptoms ever, and the current symptom degree is asked.

* Observe the significant difference between elevation and weather. By a pair of t-tests (p = 0.0352)

In addition, at the end of the three-day sleep experiment, as a comprehensive assessment, from the viewpoint of fatigue recovery of neck shoulder back pain (see Table 4), from sleep to sleep (Table 5) and from the viewpoint of inducing a pleasant wake up and sleep (see Table 6) The rank of a good duvet was ranked in the order of 1-3.

Rank of futon with good weather, stiff neck, shoulders, back and waist and pain recovery Item Standard duvet Development comforter Boardless comforter ranking 2.58 1.08 ** 2.33

** Observed significant differences between 3 futons (variance analysis).

Ranking of futon with good sleep and good night's sleep Item Standard duvet Development comforter Boardless comforter ranking 2.50 1.45 ** 2.04

** Observed significant differences between 3 futons (variance analysis).

Rank of futon that comfort of weather and sleeping is good Item Standard duvet Development comforter Boardless comforter ranking 2.66 1.00 ** 2.33

** Observed significant differences between 3 futons (variance analysis).

As a result, in the present invention (development duvet), the Borg index improvement of systemic fatigue (see FIG. 5), neck and shoulder stiffness pain (see FIG. 6) and stiffness pain in the lower back (see FIG. 7) compared to before bedtime All of them were satisfactory, and significant differences were observed. In the other two blankets, no significant difference was observed in the Borg index before bedtime and during wake up. The Borg index for low back pain, on the other hand, on standard and futonless boards, tends to be more appealing in weather conditions.

In the overall evaluation, the present invention (Development Futon) showed the highest ranking in all respects, and significant differences were observed. These sleep investigations have shown that the present invention (Duvet) is effective in improving fatigue, stiff shoulders, and low back pain compared to standard duvets.

In addition, the comparison of the state of the board with the board removed shows that the quilt with the board improves the Borg index of systemic fatigue and stiffness and pain in the neck and shoulders, and stiffness and pain in the neck and shoulder compared to the quilt with the board removed. In this favorable point, it was shown that the structure of the board combined with the cushion of the futon has a recovery effect of systemic fatigue, stiff shoulder pain, and stiff back pain at bedtime.
