DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air mat.

[0002]

2. Description of the Related Art A conventional air mat is provided with an air port for taking in air at an end of a plurality of substantially cylindrical air bags formed independently or continuously integrally, and from one end side in the direction in which the air bags are arranged. The expansion and contraction are performed in the forward direction on the other end side, for example, →→→→, and this is repeated.

It has also been considered that two air bags adjacent to a part of the air bag are inflated at the same time, or an operation such as starting to inflate before the air bag is contracted.

[0004]

However, since each operation is monotonous simply by pressing the contact portion in order with the inflated body portion of the air bag, the effect of massage and fibrillation of the contact portion is thin. Met. Also, 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 was difficult to fix the air bag, and inside the mat body In addition to the displacement of the air bag, the positions of the hose and the urethane foam of the core material were not fixed, and there was a disadvantage that the massage effect was insufficient due to free movement. On the other hand, if the position of the air bag is fixed with a string or the like, the air bag is inflated, and the string cannot be completely shrunk by pulling the string, so that excessive tension is applied to the air bag and the air bag is broken.

Accordingly, it is an object of the present invention to provide an air mat which can provide a sufficiently effective massage and eliminate body stiffness. Another object of the present invention is to provide an air mat which can provide a sufficiently effective massage, has no obstacle to inflation and shrinkage of the air bag, and does not allow the air port to be felt by the body even when a person is placed on the air bag.

[0006]

In the air mat according to the first aspect, 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 .
A back straightening air bag is placed on a part of the plurality of air bags.
A wet air mat, wherein the air supply control device is:
Along with repeatedly inflating and contracting the plurality of air bags sequentially from one end to the other end in the arrangement direction, causing the air bags at an arbitrary position to perform a retreat operation in the direction opposite to the moving direction of inflation and contraction a plurality of times in the process of sequentially repeating, At this time, the range of the current retraction operation is moved to the
And, the air bag for stretching the spine is stacked
At the same time when the air bag is inflated,
It is characterized by being made inflatable .

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 in the mat body, so that they can be used as a normal mat and a massage mat. At the same time, in the one-way movement by sequentially repeating the inflation and deflation of a plurality of air bags, a retreating operation in the opposite direction to the movement direction was inserted, so not only the body was simply pressed, but also the difference in height of the inflation and deflation of the air bags. By successively changing the parts while adding to a part of the body, each part will not only press on the upper surface but also fir movement, so only the body will loosen and a more effective massage can be done, Eliminates body stiffness.

According to a second aspect of the present invention, there is provided the air mat according to the first aspect, wherein an air port for taking in air is protrudingly provided substantially at the center of the lower surface of each of the plurality of air bags, and the air port is formed by the air bag of the mat body. Through the through hole provided on the mounting surface
Engaging with the locking portion. According to the air mat of the second aspect, in addition to the same effect as the first aspect, since the air port projects from the substantially central lower surface of the air bag and engages with the locking portion of the mat body, Since there is no movement of the bag, it is possible to perform a sufficiently reliable massage, there is no obstacle to the expansion and contraction of the air bag as compared with the conventional example in which the air bag is fixed with a string, and the air port is located at the substantially lower center of the air bag. Therefore, even if a person puts on the air mat, the air vent does not feel to the body and there is no uncomfortable feeling.
