Description

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

Traditionally, mattresses are representative bedding that can be used for Japanese people's peaceful sleep together with comforters. It is summarized as follows.
1) Reduce the pressure per unit area of the contact surface and avoid a feeling of pressure by softening the hardness of the contact part between the body and the mattress in the sitting or sleeping position and receiving body pressure over a wide area What is designed is common. A typical example is a low resilience pillow or a low resilience futon.
2) It was considered desirable to lie down and cushion with little body movement.

  Under such circumstances, there has been known a proposal for a multilayer mattress that reduces the concentration of body pressure at the time of going to bed and does not feel a feeling of pressure during sleep (see, for example, Patent Document 1).

  However, in previous studies, there is no ideal posture that can be maintained for a long time. When sleeping or sitting continuously for several hours or more, compression or tension occurs in specific parts or muscles, resulting in circulatory disturbance. And muscle fatigue, causing back pain and pressure ulcers due to circulatory disturbance.

  Therefore, the present invention is to develop and provide a mattress, a pillow, a bed mat, and a cushion with less fatigue while being in a sitting position, which can guarantee a comfortable sleep and awakening.

  As a means for solving the problems due to this device, the mattress, pillow, bed mat and cushion are composed of a plurality of layers, promote body swinging at bedtime, stiff muscles due to circulatory disturbance caused by a fixed posture, The present invention provides a cushion, a pillow, a bed mat, and a cushion that can prevent fatigue and sticking (floor rubbing), and that is less fatigued even if the sitting posture is maintained for a long time.

  According to this device, mattresses, pillows, bed mats and cushions are formed in multiple layers, the surface is provided with a highly repellent surface material having a body pressure dispersion layer, and the next layer is a rigid body separated from the upper and lower layers In addition, a lightweight board material is provided so that the body and head do not sink while sleeping. A further important effect is that the intermediate board material is a rigid body, so that the so-called hammock phenomenon by the conventional cushion, that is, the cushion bends due to the body weight and becomes a hammock state (valley bottom state), which makes it difficult to move. In the case of turning over in the horizontal direction in cooperation with the elastic action of the elastic member at the bottom, the board tilts to the side of the turn and plays the role of a seesaw as the weight moves in the horizontal direction. By demonstrating the action to promote, you can easily turn over, get tired easily, you can not turn over, and when sinking, the water that occupies 70% of the human body does not accumulate towards the bottom, The cause of floor rubbing is eliminated.

  In addition, this device is made by using natural rubber foam material [hypoallergenic latex (tannic acid latex) for the surface material (1) made of highly resilient material and the bottom material (2) made of highly resilient material. Unlike synthetic rubber, natural rubber does not use proteins that cause allergies, and therefore has the effect that even people with allergic symptoms can use it with peace of mind.

  Furthermore, by forming the cross section of the board material (2) in an arc shape with the center portion bulging, and by lying down the body in the center portion, the board material (2) becomes horizontal due to the weight of the body. Thus, it is possible to turn over easily without turning into a sink as in the prior art, and to easily turn over and prevent the body from flowing to the lower side.

  Also, the board material (2) is a three-part board where the waist, head and feet are located, and the repulsive force of each part is increased by increasing the waist board material (2) and the head board material (2 ) In the middle and by changing the foot board material (2) to be small, these three-part boards can be kept horizontal in all directions.

  Further, the board material (2) is a three-part board where the waist, head and feet are located together with the surface material (1) and the bottom material (3). By covering with the material (5) and detachably engaging with these fasteners (6), it can be connected when used, and can be divided into three when not in use and stored in a closet or the like.

It is a front view which shows one Example of this device. It is a partially broken plan view of the board material used for this device. The use state of this device is shown, (a) is a front view when stationary, (b) is a front view when swinging. It is front view explanatory drawing at the time of a stationary state which shows the use condition of the mattress which incorporated the additional technical means in the basic composition of this invention. Another Example of this invention is shown, (a) is a plan view, (b) is a partially cutaway side view.

  Hereinafter, for a preferred embodiment of the present invention, in the mattress, pillow, bed mat and cushion, it is formed in a three- to five-layer structure, and the surface material and the bottom material are formed in the body pressure dispersion layer, The intermediate layer of the surface material and the bottom material is composed of a mattress, a pillow, a bed mat, and a cushion in which an elastic body layer is formed through a rigid and lightweight material with little bending. Further, a bank-like slope for preventing falling down is provided on the lateral edge of the surface layer of the mattress, pillow, bed mat or cushion in order to promote rolling in the lateral direction. Further, the lowermost elastic body layer is provided with conical or hemispherical irregularities in the upper surface direction so that the board can be easily tilted and swung, and the body can swing and turn over easily.

  In addition, an air layer is provided between the surface layer and the board layer to lower the air pressure at the beginning of bedtime, increase cushioning, increase body pressure dispersion, make it easier to sleep, and gradually increase the air pressure from about 30 minutes after bedtime. It has a structure that makes it easy to swing and turn over by preventing the sinking of the body while sleeping. The air pressure can be adjusted by adjusting the time according to the personal sleeping tendency by providing a timer in the pump. Alternatively, an acceleration sensor may be provided on the mattress or pillow so that the time when the body movement becomes small for a certain period of time is determined to fall asleep, and the air pressure is gradually increased from this point. The reason for this is that it is easier to fall asleep for 30 minutes before going to sleep if the body pressure dispersibility is increased. This is because the structure that promotes body movements can maintain a comfortable sleep on the blood circulation of the body after falling asleep for over 30 minutes.

  Next, a mattress, pillow, bed mat and cushion having a three-layer structure according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. And a surface material (1) made of a highly resilient material, and a bottom material (3) made of a highly resilient material, like the surface material (1), and a surface material (1) It is composed of a mattress, a pillow, a bed mat and a cushion, characterized in that a rigid board material (2) is provided between the bottom material (3).

  First, the surface material (1) having a body pressure dispersibility and made of a highly repulsive elastic body is made of latex, and the thickness of the surface material (1) is about 2 cm. Here, in order to enhance the soft feeling of the outermost surface layer, the upper layer may be a softer layer, and the surface material (1) may have a two-layer structure, for example, the second layer may have a high resilience.

  Conventional latex materials may cause rubber allergies, and hypoallergenic latex (tannic acid latex) is preferably used to prevent this.

  The bottom surface material (3) located on the bottom surface is made of latex as in the case of the surface material (1), and has a thickness of about 5 cm. The hardness may be selected as appropriate by changing the foaming ratio to three types of 15 times, 20 times and 30 times.

  Latex, which is a material of the surface material (1) and the bottom material (3), is made of a natural rubber foam material, has a durability of 10 years, and is biodegraded in 6 to 7 years. Incidentally, synthetic latex lasts a long time considering that it will deteriorate in 2 to 3 years. Latex is a term that refers to raw rubber raw materials, and also refers to synthetic rubber raw materials.

  Furthermore, the board material (2) is a high-performance resin called PS / PE copolymer resin “Piocelan” (trademark: manufactured by Sekisui Plastics Co., Ltd.), which has excellent high-strength absorption and high rigidity. And it is a board material which consists of a recyclable foam, The thing which changed foaming magnification can be used in order to adjust hardness and lightness.

  Then, as shown in FIG. 2, the board material (2) is made of expanded polystyrene and has a plurality of through holes (2a), thereby providing air permeability and providing the surface material (1) and the bottom surface. The material (3) is formed so as to be able to vent, and by forming a plurality of through holes (2a), a frictional force between the surface material (1) and the bottom material (3) is secured, and these As described above, the board material (2) is lightweight, and the hardness can be adjusted by changing the magnification.

  Although the present invention shows a three-layer structure, it may be a four-layer or five-layer structure. In the state of use of the present invention, the mattress, pillow, bed mat, and cushion are used in the human body (X ) Is in a static state, as shown in FIG. 3A, and when the human body moves (X), such as turning over or swinging, as shown in FIG. 3B. It is.

  Here, in order to promote turning over in the lateral direction, modifications such as providing a bank-like slope to prevent falling down on the lateral edge of the surface layer (1) of the mattress, pillow, bed mat or cushion are considered. [See FIG. 4].

  Further, the lowermost elastic body layer (3) has conical or hemispherical irregularities in the upper surface direction so that the board (2) can be easily tilted and swung, and the body can swing and turn over easily. Is also considered [see FIG. 4].

  Furthermore, as an active means configuration, as shown in FIG. 4, an air layer (4) is provided between the surface layer (1) and the board layer (2), and the air pressure is low at the start of going to bed and the cushioning property is good. However, by increasing the dispersion of body pressure, it is easy to fall asleep, and gradually increase the air pressure from about 30 minutes after going to sleep and make it highly repulsive, thereby preventing sinking of the body while sleeping and swinging and turning over In some cases, the structure is made easy. The air pressure can be adjusted by providing a timer for the pump (P) and appropriately adjusting the time according to the personal sleep tendency. Alternatively, a plurality of commercially available acceleration sensors may be provided in the center of the mattress so that the time when the body movement decreases for a certain period of time (about 5 minutes) is determined to be asleep, and the air pressure is gradually increased from this point. . The reason for this is based on the experimental results that about 30 minutes before going to sleep after going to bed are more likely to fall asleep when the body pressure dispersibility is increased. After falling asleep, a structure that increases air pressure, reduces body sinking, and promotes turning over and body movement avoids pressure ulcers by avoiding blood pressure in the body and concentrating pressure on certain parts of the body. This is because it can prevent, maintain a comfortable sleep, and ensure a comfortable sleep.

  The board material (2) is a three-part board where the waist, head and feet are located together with the surface material (1) and the bottom material (3). The material (1) and the bottom material (3) are covered with a cover material (5) comprising a washable cover, and these three-part boards are configured to be detachably engaged with fasteners (6). At times, it is engaged / coupled with a fastener (6), removed when not in use, and reduced in bulk to be conveniently stored in a closet or moved / conveyed (see FIG. 5).
