Description

  The present invention relates to a body ventilation device that is used on a body support device such as a mattress or a futon bedding or a body support device such as a chair, or configured as or a part of the body support device itself.

  When lying or sitting on a body support device such as a mattress or bedding such as a futon or a chair, the heat and moisture emitted from the body may cause the body to become stuffy and uncomfortable. In order to improve such body stuffiness, various body support means have been proposed in which heat and moisture are exhausted by ventilating air from the body side surface of the body support device. ing.

  For example, in Patent Document 1, an airflow overlay composed of an upper surface cover provided with a large number of openings for blowing air and an air passage member formed of a three-dimensional fabric is detachably attached to the upper surface of the mattress and is used for ventilation. An air flow passage leading to the air pump is opened through the upper surface of the mattress in the space constituted by the upper cover, and the air pressure-fed from the air pump is provided in the upper cover for the space formed by the upper cover for ventilation. A mattress is described which is adapted to be ejected from a number of openings. Further, in Patent Document 1, an interior material such as a three-dimensional woven fabric or a urethane foam material is accommodated in a ventilation cloth bag provided with an air-permeable top cover so that air can be circulated in the interior. There is described a blower pad that is configured to allow air blown from an upper surface cover to be blown from an air pump. In this blower pad, a plurality of sections are formed which are partitioned by a boundary closing means that can be opened and closed. By closing the boundary closing means, air can be supplied to only a desired section to allow ventilation. It is configured as follows.

  Further, in Patent Document 2, a bed having an air conditioner that holds a flexible and breathable floor cloth portion over a back plate via a spring member and blows air into a space portion between the bed cloth portion and the back plate. Are listed. In this bed, the conditioned air supplied into the space by the air conditioner is ejected upward from the floor covering having air permeability.

  Further, Patent Document 3 discloses an internal air-permeable layer made of a surface air-permeable layer made of a material having flexibility and air permeability and a material having flexibility and air-tightness and having a plurality of air holes formed at predetermined intervals. Air is supplied from an air supply source to the internal ventilation layer formed between the internal air-impermeable layer and the back-surface air-impermeable layer by superimposing a layer and a back-air-impermeable layer made of a material having flexibility and airtightness. And the air mat comprised so that air may be ejected from the surface ventilation layer through a ventilation hole is described. And in this patent document 3, the air supplied from the inflow port is moved away from the air inlet by increasing the number of the air vents by decreasing the formation interval of the air vents away from the air inflow port. It is described that it is distributed.

  Further, Patent Document 4 describes an air mat that can adjust the amount of air ejected from the air ejection hole by forming a large number of air ejection holes formed on the surface side of the air mat body so as to be openable and closable. ing.

Patent Document 5 describes a futon side using a high-density fabric having a low air permeability of 3 cm ³ / (cm ² · sec) or less in order to prevent down cotton from blowing in a duvet. .
Japanese Patent Laid-Open No. 10-165259 Microfilm of Japanese Utility Model No. 56-147045 (Japanese Utility Model Publication No. 57-81664) JP 2005-270568 A Japanese Patent Laid-Open No. 7-88021 JP 2007-126777 A

  As described above, in the conventional body support device that ventilates air from the body-side surface in the direction of the body, a number of air ejection holes are provided on the body-side surface, or the body side The surface is formed of a sheet-like material having good air permeability so that air is ejected.

  However, air blowing holes and air-permeable sheet-like materials facilitate the air flow through them due to a slight pressure difference between the inside and outside, so air supply from the air pump to the air bag, air pad or body support device As the air supplied to the section is closer to the air supply section, a larger amount tends to be ejected, and there is a tendency that the amount ejected from a distant place decreases.

  For this reason, when the air supply unit is installed on a person's foot side as in the bed of Patent Document 1, a large amount of the supplied air is ejected from the foot side, which is a high sweating site. There is an inconvenience that it is difficult to be ejected from a place corresponding to the thigh or the trunk.

  In order to prevent such inconvenience, if an air supply unit is provided in the vicinity of a high sweating site, a metal fitting or a tube for supplying air easily hits the body, and the sleeping comfort is deteriorated.

  On the other hand, as shown in Patent Document 3, even if the number of ventilation holes is varied depending on the distance from the air supply unit, it is relatively difficult to average the amount of air jetted. As described above, when the air ejection hole is formed to be openable and closable, it becomes complicated and expensive, and the sleeping comfort is also deteriorated.

  In addition, the conventional body support apparatus described above is basically configured to eject air from the entire surface on the body side, and air from only a desired part of the body side surface. It is not assumed that air is blown out or air is blown out from a plurality of desired locations on the body-side surface.

  On the other hand, in the blower pad of Patent Document 1, a plurality of compartments are formed by the boundary closing means that can be opened and closed, and air is supplied to only the desired compartments for ventilation by the operation of closing the boundary closing means. However, in the end, it is only possible to perform the operation of ejecting air from the downstream section or stopping the ejection of air. In order to eject air, an air supply unit must be configured for each section.

  The present invention was devised in view of the above points, that is, to provide a body ventilation device capable of rationally ejecting air from the body side surface for good ventilation. It is intended.

  In order to solve the above-described problems, in the present invention, a ventilation formed of a sheet-shaped material having a low air permeability on a body-side surface of a flat air bag capable of storing air with a sheet-shaped material having no air permeability. The apparatus for body ventilation which provided the part and provided the air supply part in the appropriate place of the said flat air bag is proposed. Further, the present invention proposes that the air supply unit is provided only at one place in this configuration.

  Further, the present invention proposes that the sheet-like material having a low air permeability is composed of a high-density cloth in the above configuration.

  Further, the present invention proposes that, in the above configuration, the ventilation portion is provided on the entire surface on the body side.

  Further, the present invention proposes that, in the above configuration, the ventilation portion is provided on a part of the body-side surface.

  Further, the present invention proposes that, in the above configuration, the ventilation portions are provided at a plurality of spaced locations.

  In the present invention, it is proposed that in the above configuration, ventilation portions having different air permeability are provided.

  The present invention proposes that the air channel member is housed in the flat air bag in the above-described configuration.

  Furthermore, in this invention, it proposes that an air flow path member is a solid knitted fabric in the above structure.

  Furthermore, in the present invention, it is proposed that in the above configuration, the flat air bag is used by being placed on a body support device such as a mattress or a chair.

  Furthermore, in the present invention, it is proposed that in the above configuration, the flat air bag is configured as a body support device such as a mattress or a chair.

  In the present invention, since the ventilation portion is made of a sheet-like material having a low air permeability, in order to eject air from the ventilation portion, it is compared with a ventilation hole or a ventilation portion made of a sheet-like material having good air permeability. Therefore, a larger internal and external pressure difference is required. For this reason, the air supplied from the air pump via the air supply part is expanded and stored in the flat air bag without substantially being ejected from the ventilation part until a predetermined internal / external pressure difference is obtained, and thus the flat shape When air accumulates in the air bag and the pressure difference between the inside and outside reaches a predetermined pressure, the air bag ejects.

  In this way, air can be blown out on average from the ventilation part provided on the body side surface regardless of the distance from the air supply part. Can be suppressed.

  For this reason, the ventilation part can be provided on the whole body side surface of the flat air bag, or on a part of it, and can be provided at a plurality of spaced locations, or the ventilation part of different air permeability, and therefore the air Ventilation portions with different ejection amounts can be easily configured.

  As described above, the present invention is capable of ejecting air at an arbitrary position on the surface of the body very rationally as described above. However, since the main component is a sheet-like material, it can be manufactured at low cost. Can do. In particular, the cost can be further reduced by providing the air supply unit only at one location.
