TECHNICAL FIELD The present invention relates to an air mat.

[0002]

2. Description of the Related Art In a conventional air mat, an air inlet for taking in air is provided at an end portion of a plurality of substantially tubular air bags which are formed integrally or independently and continuously from one end side in the arranging direction of the air bags. For example, the other end side is subjected to sequential expansion and contraction in the order of →→→→, which is repeated.

Further, it has been considered that two air bags adjacent to a part thereof are inflated at the same time, or an operation such as inflating is started before the air bag is contracted.

[0004]

However, since all the movements are monotonous by simply pressing the contact portion in order with the inflated body part of the air bag, the effect of massage and loosening the contact portion is small. Met. Also, in order to prevent the hardness of the hose connected to the air bag and the hardness of the air port from being transmitted to the body, the air port was provided at the end, but it is difficult to fix the air bag and There was a drawback that the air bag was misaligned and the foaming urethane of the hose and the core material could move freely without the position being fixed and the massage effect became insufficient. On the other hand, if the position of the air bag is fixed with a string or the like, the expansion of the air bag is hindered, and the string cannot be completely contracted by pulling the string, and excessive tension is applied to the air bag, causing the air bag to break.

[0005] Therefore, an object of the present invention is to provide an air mat which is capable of performing a sufficiently effective massage to eliminate body lumps. It is another object of the present invention to provide an air mat which is capable of performing a sufficiently effective massage, has no obstacles for expansion and contraction of the air bag, and does not feel the air port on the body even when a person is placed on the air bag.

[0006]

The air mat according to claim 1 is a mat in which a plurality of air bags for massage, which can be inflated and contracted under the control of an air supply controller, are arranged side by side on a mat body. The air bag is repeatedly inflated and deflated from one end to the other end in the arranging direction, and a retreating operation in a direction opposite to the moving direction of the inflation and deflation is inserted in the process of being sequentially repeated.

According to the air mat according to the first aspect of the present invention, a plurality of air bags for massage, which can be inflated and contracted under the control of the air supply control device, are arranged side by side on the mat body. At the same time, a backward movement in the direction opposite to the moving direction is inserted in the movement in one direction by sequentially repeating the inflation and deflation of multiple air bags, so not only the body is simply pressed, but also the difference in height of inflation and deflation of the air bags. By gradually changing the part while adding to the part of the body, not only the compression of the upper surface of each part but also the kneading action occurs, so that only the body loosens, and more effective massage can be done, It eliminates body stiffness.

The air mat according to claim 2 is an air mat in which a plurality of air bags for massage, which can be inflated and contracted under the control of an air supply control device, are arranged side by side on the mat body, each of the plurality of air bags. An air port for taking in air is formed in the approximate center of the lower surface of the mat, and this air port is engaged with the engaging portion of the mat body. According to the air mat according to claim 2, since a plurality of air bags for massage, which can be inflated and contracted under the control of the air supply control device, are arranged side by side on the mat body, the air mat can be commonly used as a normal mat and a massage mat, and at the same time, the air mat can be used. A massage can be obtained by controlling the bag with an air supply control device, and the air bag can be moved because the air port is projected on the lower surface of the center of the air bag and engages with the engaging part of the mat body. Since there is no massage, there is no obstacle of expansion and contraction of the air bag compared to the conventional example in which the air bag is fixed with a string, and since the air port is located at the approximate center lower surface of the air bag Even if it is placed on an air mat, the air vent does not feel on the body and there is no discomfort.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this air mat is applied to a warm air futon, has a mat body 1, and is supplied with air from an air supply controller 4. The mat body 1 has a length that allows a human body to lie on the surface, and as shown in FIG. 5, the mat body 1 is divided into a head portion 11, a torso portion 12, a foot portion 13, and a device portion 14, and these are rotatable. The hinge portions 15 are connected to each other and can be folded as shown in FIG.

As shown in FIGS. 3 and 4, the trunk 12 is formed by laminating three layers of core bodies 5 to 7 and two layers of pads 8 and 9 and covering the entire outer surface with a mat cover 10. . The core bodies 5 to 7 may be made of slightly hardened urethane foam or the like, and the core body 5 may be made of foamed urethane softer than the core bodies 6 and 7. The urethane foam can also be made of elastically equivalent artificial or natural cotton. A hose through hole 16 also used for fixing an air bag is vertically formed in the core body 5, and a hose guide groove 17 is formed in the core body 6 in a horizontal direction.
The pad 9 is made of urethane foam, cotton such as natural or synthetic fiber feathers, and the opening 1 for storing the air bag.
8 is formed, and the second air jetting mat 25 is attached to the upper surface.

As shown in FIG. 2, the mat body 1 except for the trunk legs 12 is formed of a urethane layer 19 and a pad layer 20. The foot portion 13 includes the urethane layer 19 and the pad layer 2
The storage recesses 21 and 22 are formed in the storage recess 0, and the
The air jetting mat 23 is stored, and the heating element 24 is stored in the storage recess 21. First air jet mat 2
3 is built in the foot side of the mat body 1, that is, the foot portion 13, the second air jetting mat 25 is built in near the center of the mat body 1, that is, in the trunk leg portion 12, and the air jets the first air jetting. The second air jetting mat 25 is connected in series to the first air jetting mat 23 so as to be supplied to the second air jetting mat 25 through the air jetting mat 23, and the first air jetting is performed. A heating element 24 is arranged below the mat 23.

First air jetting mat 23 and second
In the air jet mat 25, the dot-like joint portions 33 are formed at substantially equal intervals as shown in FIG. 12, and the air jet holes 34 are formed between the joint portions 33. Also, one or more air hoses 2 connected to air ports (not shown)
7 ', which are connected to each other in series, and further from the first air jetting mat 23, the control unit 3 of the air supply controller 4
Connected to 1 and controlled. Therefore, when air is sent from the control unit 31 to the first air jetting mat 23, the air is blown out from the air jetting holes 34 of the first air jetting mat 23 and the air hose 27 is blown from the first air jetting mat 23. The air is supplied to the second air jetting mat 25 through the ‘′’ and is blown out from the air jetting hole 34 to remove the moisture.

The heating element 24 is disposed on the lower surface of the first air jetting mat 23, and is electrically controlled by the control section 31 to warm the foot portion 13 and blow the air blown from the first air jetting mat 23. Since the second air jetting mat 25 is connected in series to the first air jetting mat 23, a part of the warmed air is discharged from the air jetting holes 34 of the second air jetting mat 25. Blow out. The shapes of the first air jetting mat 23 and the second air jetting mat 25 may not be the same but may be different from each other.

Below the second air jetting mat 25, a plurality of air bags 2 for massage, which can be inflated and shrunk under the control of the air supply controller 4, are arranged in parallel. A plurality of air bags 2 are arranged in the height direction of the human body lying on the surface of the mat body 1, that is, in the longitudinal direction, and due to the expansion of the air bag 2, the surface 2 of the mat body 1 where the air bag 2 is located.
The air bag 2 is housed inside the mat body 1 so that the air bag 6 swells. That is, in the embodiment, the number of the air bags 2 is 5, and the air bags 2 are stored in the air bag storage opening 18 of the pad 9. Each air bag 2 has an air port 28 for projecting air at the center of the lower surface thereof, and the air port 28 is fitted into the through hole 16 of the core body 5 serving as a locking portion of the mat body 1 to attach to the mat body 1. It is positioned and fixed, and is connected to the hose guide groove 17 of the core body 6 and the air hose 27 passing through the through hole 16 of the core body 5. Further, both ends of the air bag 2 are formed thinner than the central part as shown in FIGS. 8 and 9. This is because if both ends are made substantially the same as the central part, the mat covers 10 at both ends of the mat body 1 may be swollen and damaged when the air bag 2 is inflated. This is because it is possible to greatly inflate the central portion, which is easy to catch, so that the weight can be supported almost uniformly over the entire body.

The air bag 2 for stretching the spine of the back is overlaid on the air bag 2 at a position corresponding to the lumbar spine of the body of the mat body 1, and the surface 2 of the mat body 1 due to the expansion of the air bag 2
The surface 26 is swollen higher than the swollen height of 6 so that the back muscles can be stretched. Air bag 2 for overlapping the back stretching air bag 3 and the back stretching air bag 3
Is composed of four sheets, and FIG.
As described above, the upper two sheets form the air bag 2, the lower two sheets form the back stretching air bag 3, and the central two sheets are joined together so as not to communicate with each other. Are integrated. These sheets are made of an elastic material such as vinyl chloride or urethane rubber, and when they are inflated, they are laminated or sandwiched with a core fiber on the surface or inside of the sheet material to prevent overexpansion like a balloon. I am doing it. This is effective in maintaining the hardness of transmitting the pressure when the air bag 2 is inflated to the human body.

The air supply controller 4 supplies air to the first air jetting mat 23 and heat-generating element 24.
Is controlled, and air is further supplied to the air bag 2 and the back stretching air bag 3. As shown in FIG. 7, the air supply control device 4 includes an air pump 30, a control unit 31, and an operation unit 32. The first air jetting mat 23 is connected to the control unit 31 by an air hose 27 '.

Has a function of switching, etc., the operation of the air pump 30, the supply of air to the first air jet mat 23 and the second air jet mat 25, the order of air supply to the air bag 2, and the stretching of the spine. It controls the supply of air to the air bag 3 for use.

In this slightly warm air futon, the air supply controller 4 is controlled to control the first air jet mat 23 and the second air jet mat 23.
Air is spouted from the air spouting mat 25 to remove moisture in the summer. Further, the heating element 24 is caused to generate heat to heat the air of the first air jetting mat 23, and the first air jetting mat 23 and the second air jetting mat 2 are heated.
Blow off a slight warm air to warm the body and dehumidify it. In this case, the second air is injected onto the first air jetting mat 23.
Since the air jet mats 25 are connected in series, the air blown from the second air jet mat 25 is lower than the temperature of the air blown from the first air jet mat 23 by cooling, and therefore the head is warmed up. Can be achieved and comfort is improved.

When massaging is performed with the warm air futon, the air supply control device 4 is controlled to inflate and contract the air bags 2 in a predetermined order. For example, in FIG.
In addition, if the designated numbers from left to right are added to the air bag 2, in addition to repeating in the order of → → → →,
It includes an operation of sequentially inflating and contracting each of the air bags 2 from one end side to the other end side in the arrangement direction and retracting in the opposite direction to the moving direction in the course of the movement. For example, → → → → → → → → → →
→→→→→
→ → → → → → When repeating in order, →
It may be repeated in order of →→→→→→, and an effective massage can be performed with a fir-relaxing action.

When the back muscles are stretched, the air supply controller 4 is controlled to inflate the back muscle stretching air bag 3. In this case, it is effective to inflate the air bag 2 and the back muscle stretching air bag 3 at the same time. When performing a massage and stretching the back muscles, the massage operation and the back muscle stretching operation are performed at the same time. For example, if you specify the air bag 3 for straightening your back muscles with, →→→→→→
And do it.

Due to the above-mentioned structure, the low temperature air futon is provided with the second air provided near the center of the mat body 1 through the first air jetting mat 23 provided at the foot side of the mat body 1. Since air is supplied to the ejection mat 25 and the heating element 24 is arranged below the first air ejection mat 23, the first air ejection mat 23 and the second air ejection mat 23 are arranged. It can be dehumidified with 25 warm air, and the back is warmed at a temperature lower than the temperature at the feet, which causes cold head and foot heat, which increases comfort.

Since it is locked, there is no movement of the air bag 2, so a reliable massage can be performed,
Compared with the conventional example in which the air bag 2 is fixed with a string, there are no obstacles to expansion and contraction of the air bag 2, and since the air port 28 is located on the lower central surface of the air bag 2, a person can sit on the warm air futon. Also, the air vent 28 is not felt by the body and there is no discomfort.

Further, a plurality of air bags 2 for massage, which can be inflated and contracted under the control of the air supply control device 4, are arranged side by side below the second air jetting mat 25 of the mat body 1, and the air bags 2 are provided. Each of them is repeatedly expanded and contracted from one end side to the other end side in the arranging direction, and in the process of its movement, it is retracted in the direction opposite to the moving direction. Therefore, it is not only a simple pressure on the body,
By gradually changing the parts while adding the height difference of the expansion and contraction of the air bag 2 to a part of the body, each part not only compresses the upper surface but also has a kneading motion, so that only the body has a loosening action, A more effective massage can be achieved and the body stiffness can be eliminated.

13 and 14 show another embodiment of the first air jetting mat 23 and the second air jetting mat 25. That is, FIG. 13 is divided into two chambers A and B, and these chambers are alternately expanded and contracted to have a body pressure converting function. In addition, in FIG. 14, the air ejection holes 34 are provided only in one chamber C divided into three chambers A to C, and the other chambers A and B are alternately expanded to have a body pressure converting function, and at the same time, to provide air pressure. It is possible to turn the jet on and off.

The size and number of the air bags 2 are determined by the comfort of the massage effect and the ambient conditions such as the hardness of the core body, and are not limited to the above embodiment. For example, the air bags 2 may not all have the same size but may have different sizes so as to fit the shape of the back. It is also possible to detect the pressure by a pressure sensor, a diaphragm or the like with respect to the backward movement of the air bag 2 in the expansion / contraction movement direction, and perform the backward movement within a certain range of preload.

If there are a plurality of air bags 2 for stretching the back muscles at a position corresponding to the lumbar spine of the back muscle, a plurality of air bags 3 can be prepared and stacked on each other. The back straightening air bag 3 and the air bag 2 overlapping therewith have a two-layer structure, but may have a structure of three or more layers, and the back straightening air bag 3 may be located below the air bag 2. .
