Air mattress and manufacturing method

The present invention relates to an air mattress and a manufacturing method, and more particularly, an air mattress which improves the functionality and ease of use of a mattress by combining a main cushion layer made of an air mat and a sub cushion layer made of a material such as a polyester nonwoven fabric. And to a manufacturing method.

In general, the mattress is to give comfort to the human body during sleep or rest, the type of mattress is a mattress that is used to install a steel spring inside, there is a mattress used to fill the water inside, There is an air mattress used to fill the air.

However, the mattress using the steel spring as a cushion member is subjected to excessive pressure on the contact portion due to the structure in which only a part of the user's body comes into contact with the mattress at bedtime, and the elasticity of the spring is weakened as the mattress is used for a long time. Difficult to maintain, there is a problem that noise occurs in use, the weight of the mattress is heavy and difficult to reduce the volume there is a problem in transport.

In addition, the mattress used to fill the water inside is not only heavy due to the nature of the water, but also has the trouble of removing the water inside during transportation and filling the water again during installation, and also damaged the outer shell or long-term use As a result, when the joint is aged and water is leaked, the damage becomes very large.

Air mattresses filled with air are generally formed to be sealed in a rectangular shape with an airtight cloth, and used by injecting air therein, which is easy to inject and discharge air, which is easy to carry and move. In addition, in use, the user's weight is evenly distributed throughout the mattress.

Since only a part of the body does not receive excessive pressure, it is used for leisure or bedding, and also for medical devices such as preventing bedsores.

Such an air mattress maintains its shape by erecting a reinforcing rod or keeping a plurality of fiber yarns connected up and down in order to maintain a shape according to air characteristics.

By the way, when the air mattress is used by one person, there is no problem, but when two people use it as bedding, the vibration caused by the movement of one person is transmitted to the person next to them, and the rest is prevented, especially when sleeping. There is a problem that interferes with sleep.

In addition, in the case of the existing air mattress is not equipped with a protective member to hold the edge often the user falls, and there is an inconvenience in use, such as the mattress is turned off when the user sits on the edge of the mattress.

In addition, the existing air mattress uses only the main cushion layer made of PVC material, so it is less comfortable to lie down, and there is a tendency to avoid the use such as feeling foreign object when it comes in contact with the body. The disadvantage is that you can not rest comfortably.

Therefore, the present invention has been devised in view of the above, a new type of mattress that combines the sub-cushion layer of various materials up and down to the main cushion layer made of air mat, or the edge protective material at the edge of the main cushion layer By minimizing vibration transmission of the mattress body and preventing edges off, the user can get a good night's sleep without any foreign object, and maximize the comfort and comfort when using it, while also being easy to handle. An object of the present invention is to provide an air mattress and a manufacturing method.

In order to achieve the above object, the air mattress provided in the present invention is disposed above and below the main cushion layer 12 formed of the air mat 11 and the main cushion layer 12 therebetween, and the air mat is loosened. And sub-cushion layers 13a and 13b for alleviating the reaction force of the cushion inflated only in one direction, and are disposed along the edges of the main cushion layer 12 to protect the air mat in all directions and to drop the user. In the air mattress comprising an edge protector (14) to prevent the off of the edges,
The main cushion layer 12 has an air inlet 10, the sub cushion layers 13a and 13b have a thickness of 20 to 50 mm, the edge protective member 14 has a thickness of 30 to 120 mm, and the sub cushion layer ( Comprising an auxiliary cushion layer 17 on the top of 13a),
The auxiliary cushion layer 17 sewns two layers of fabric at intervals of 3 to 4 inches along the length of the mattress so as to partition the inner space between the fabrics into a plurality of independent spaces side by side in the width direction of the mattress. The space 15 is filled with a cushioning material 16, characterized in that one side of the four sides of the edge can be opened and closed.

In this configuration, the cushioning material 16 filled in the independent space 15 of the auxiliary cushion layer 17 is made of polyester fiber, 30-50% of duck down and 50-70% of polyester fiber, and 30-30 of goose down. It is preferably made of any one selected from 50% and 50-70% of a blend of polyester fibers, 30-50% of wool and a 50-70% blend of polyester fibers.

The air mattress provided by the present invention has the following advantages.

First, by using the sub cushion layer in various ways using the main cushion layer of the air mat can be used as a mattress in the bedroom, by installing a rim protection material can prevent the air mat surface damage to minimize the leakage of air.

Second, the weight of the spring, the main cushion layer of the general steel spring mattress is about 18kg in the case of a queen size (1500 × 2000mm), but the air mat of the present invention is lightweight about 3.5kg after air injection, so anyone can move and carry This is easy.

Third, the cushion can be adjusted by adjusting the air volume of the air mat, and according to the material of the sub cushion layer, the cushion of the air mat and the repulsive force inflated in one direction are alleviated to select the most suitable cushion for the user's physical condition. It is possible.

Fourth, the reason for avoiding the use of a simple air mattress as an ordinary bed mattress is that the air mat has no secondary cushion layer, and as in the present invention, various secondary cushion layers are provided to allow a comfortable rest without disturbing the user's sleep. When mattresses are manufactured and combined to be settled for the bedroom, it can help to conserve resources (iron, sponge, latex, etc.).

Fifth, the auxiliary mattress means manufactured by various methods has a great effect on patients, the elderly, bedsores patients using the bed for a long time because the active air circulation in the upper portion, the cylindrical cushion layer (40 ~ 60mm) The valleys consecutively at intervals have an effect of ensuring a comfortable sleep of the user.
