Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation pad capable of constantly ventilating a sleeping person.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. Sho 44-7783 proposes a futon in which an air circulation space is provided inside a cushion and a plurality of openings are provided on an upper surface to supply air and allow ventilation. Further, Japanese Utility Model Laid-Open No. 57-81664 proposes a bed in which temperature-adjusted air is blown into a hollow cushion to discharge the air from a permeable surface. Further, Japanese Patent Application Laid-Open No. 58-25116 proposes an air bedding in which a cloth sack which has air permeability only on the upper surface and through which temperature-controlled air flows is placed on a normal mat.

[0003]

[Problem to be solved]
The futon proposed in No. 7783 has a problem that a large amount of air is exhausted from the vicinity of the air inlet and is not evenly exhausted. Also, the bed proposed in Japanese Utility Model Laid-Open No. 57-81664 has a cavity in the cushion, and the temperature-controlled air blows from the outer periphery and the bottom surface.
There is a problem that the thermal loss is large and the capacity of the blower is large because air is supplied to a wide area of the bed.

The air bedding proposed in Japanese Patent Application Laid-Open No. 58-25116 has a problem that the mat under the cloth bag cannot be kept in a dry state because the mat is not ventilated. Further, since the temperature of the entire cloth bag is substantially uniform, it is not possible to respond to a request to set a different temperature for the feet and waist and the head. The present invention has been made in view of such a conventional problem, and has as its object to provide comfortable bedding with good ventilation and little loss.

[0005]

According to the first aspect of the present invention, there is provided an air pump for pumping air, a mattress provided with a flow passage for the pumped air and configured to allow a small amount of air to flow inside the mattress, and a mattress including the mattress. A breathable mattress having a ventilation overlay that can be freely attached to and detached from the upper surface of the vehicle, wherein the ventilation overlay has an air-permeable top cover and air that can withstand pressure when a person is supine. The air flow passage member of the mattress has a discharge port that opens below the ventilation overlay attached to the air flow mattress. (See FIG. 1).

What is most notable in the present invention is that a ventilation overlay is removably disposed on the upper surface of the mattress, and the ventilation of the ventilation overlay is improved. The airflow passage of the mattress opens below the ventilation overlay, and supplies air from below the ventilation overlay. In other words, the ventilation overlay has an upper cover with good air permeability and an air passage member that can withstand pressure when a person is lying down. The air pumped from the air pump can flow through and be blown out from the upper surface. it can. The space formed by the ventilation overlay and the mattress can be made much smaller than the space inside the mattress, and the air is blown out from only the upper surface, so that the load on the air pump is reduced. ， Power costs can be reduced.

Further, since the mattress has a small amount of air permeability, the mattress can be kept in a good dry state without imposing a load on the air pump. In order to circulate air inside the mattress, an air inlet and an air outlet may be provided, and the air inlet may be provided in an air flow passage of the mattress.

It is preferable that the air inlet of the mattress is provided with a check valve for shutting off the flow of air from the inside of the mattress to the outside. This is because dust in the mattress can be prevented from being mixed into the air passage. And
Good air permeability on the upper surface of the ventilation overlay can be easily achieved by providing an opening for air blowing in the upper surface cover, for example.
Alternatively, it can be realized by forming the top cover with a three-dimensional fabric (three-dimensional fabric) or a mesh fabric.

[0009] Further, the breathable mattress is characterized in that:
As described, the provision of the temperature adjusting means for heating or cooling the air can further enhance the comfort. That is, by circulating warm air or cold air according to the temperature of the outside air, it is possible to further improve the sleeping comfort.

On the other hand, a sixth aspect of the present invention is a ventilation pad provided with an air pump and a ventilation sack which takes in the air pumped by the air pump and blows out from the upper surface. It has an intake for the air pumped by the air, a top cover with good ventilation, and an interior material that allows the internal circulation of air even when a person is supine. At the boundary where the compressed air flows between adjacent sections or at the boundary between the air intake and the adjacent section, it is necessary to distribute or block the compressed air to the downstream section. A blower pad characterized by being provided with a possible boundary closing means.

[0011] The ventilation bag according to the present invention is provided with an air intake, an upper cover with good air permeability, and an interior material that allows the inside of the air to flow even when a person is supine. It should be particularly noted that the interior material of the ventilation bag is divided into a plurality of sections, and the boundary between the adjacent sections where the compressed air flows and the boundary between the air intake and the adjacent section. Means that a section located downstream is provided with boundary closing means capable of flowing or blocking compressed air.

That is, by opening or closing the boundary closing means, air can be flowed into or stopped from the downstream section. Therefore, air can be blown only to a desired section. As a result, it is possible to ventilate to a desired place and obtain a comfortable sleeping feeling. The air blow pad can be used not only by laying it on bedding such as a mattress or a futon, but also by itself.

[0013] As the boundary closing means, for example, there is a means as described in claim 7, wherein a so-called magic tape is used. In other words, at least an opposing bonding tape (commonly known as a magic tape) that can be separated again while maintaining its original shape by applying a force larger than the bonding force by applying a force larger than the bonding force by lightly pressing the opposing surfaces. A covering material capable of covering the joining surface of one joining tape and a covering material locking means capable of engaging and disengaging the covering material with the joining surface are provided at the boundary. By covering the joining surface with a covering material, the joining of the joining tape is avoided to enable the flow of the compressed air at the boundary, and the covering tape is separated from the joining surface to thereby join the joining tapes to each other. Thus, the flow of the compressed air can be interrupted (see FIGS. 4 and 5).

Further, as the boundary closing means, for example, there is a means for opening and closing a boundary portion by a fastener. By opening and closing the fastener, the air flow is interrupted at the boundary. The air blowing pad can be made more comfortable by providing a temperature adjusting means for heating or cooling the air. That is, by circulating warm air or cold air according to the temperature of the outside air, it is possible to further improve the sleeping comfort.
