2. Description of the Related Art In a double floor, conditioned air such as warm air or cold air is introduced into an underfloor space between a floor base and a floor panel, and this conditioned air is introduced into an air conditioning unit installed in a room that also serves as a partition. Conventionally, for example, Japanese Utility Model Laid-Open No. 60-32841 and Japanese Utility Model Laid-Open No. 3-25739 are used.
As described in Japanese Patent Publication No. JP-A-2003-242242, a ventilation hole having a slit shape is formed in the floor panel, and an air intake hole is opened in the lower surface of the air conditioning unit. The air holes of the floor panel and the air intake holes of the air conditioning unit communicate with each other by being installed so as to overlap each other in a plan view.

[0003]

[Problems to be solved by the device] However, in this way,
In the structure in which the ventilation holes are formed in the floor panel, there is a problem that the structure of the floor panel is complicated and the manufacturing thereof is troublesome, and the existence of the ventilation holes reduces the strength of the floor panel. Regarding this point, in the double floor, for the convenience of putting in and out the cords, etc., a large number of floor panels are
By laying so that a joint gap is opened between the side surfaces of adjacent floor panels, and by using the fact that this joint gap is closed with a joint cover, a vent hole is formed in the joint cover. By supplying conditioned air to the air conditioning unit through the ventilation holes, it is considered that the above-mentioned problem regarding the floor panel can be solved.

However, most air conditioning units are generally formed in a panel shape and are also used as partitions, and the intake holes at the lower end of the air conditioning unit are formed in a rectangular shape in bottom view so as to extend along the longitudinal direction of the air conditioning unit. In many cases, the joint cover is provided with a ventilation hole having the same shape as the intake hole of the air conditioning unit in a plan view, and the ventilation hole and the intake port of the air conditioning unit are simply communicated with each other. The installation posture of the air conditioning unit is limited to one posture,
There is a problem that the layout freedom of the air conditioning unit is impaired.

The present invention utilizes the joint gap between floor panels to introduce conditioned air from an underfloor space into an indoor air conditioning unit without changing the amount of conditioned air supplied to the air conditioning unit. The purpose is to expand the freedom of unit layout.

[0006]

In order to achieve this object, the present invention arranges a number of floor panels above a floor base so that a joint gap is opened between the end faces of adjacent floor panels. While laying down and closing the joint gap with a joint cover,
In a double floor that guides conditioned air to the underfloor space between the floor base and the floor panel, in the joint cover, a circular or planar view in plan view for introducing conditioned air from the underfloor space into the room. A ventilation hole having a polygonal shape is formed, or a ventilation hole having a circular shape in a plan view or a regular polygonal shape in a plan view is formed between the end faces of the joint covers which are adjacent to each other, and the ventilation hole has the same position as the ventilation hole. A joint body having a planar shape is detachably mounted, and the joint body is provided with an upward opening portion that is rectangular in a plan view and communicates with an air conditioning unit installed in a room.

[0007]

[Advantages and effects of the invention] With this structure, the upward opening portion of the joint body is rectangular in plan view, and the length dimension of the upward opening portion is made as close as possible to the width dimension of the joint cover. Even if the air conditioning unit is thin,
A large amount of conditioned air can be supplied inside the air conditioning unit.

When the vent hole and the joint body are circular in a plan view, the upward opening of the joint body can be changed to an arbitrary posture in a plan view by rotating the joint body. The air conditioning unit can be installed in any posture in plan view with the lower end of the air conditioning unit communicating with the upward opening of the joint body. When the vent hole and the joint body are regular polygons in a plan view, the posture of the upward opening portion of the joint body can be switched to a plurality of postures by changing the attaching posture of the joint body to the vent hole. You can

That is, for example, when the vent hole and the joint body are square in plan view, the joint body can be changed into two postures such that the upward openings thereof are in the postures orthogonal to each other. In the case of a regular hexagon, the posture of the upward opening can be changed to three postures so that the upward opening can be rotated by 60 ° in plan view. Therefore, the air conditioning unit can be changed into a plurality of postures with the upper opening of the joint body fitted to the lower end of the air conditioning unit.

As described above, according to the present invention, the air conditioning unit can be changed to an arbitrary posture or a plurality of postures in plan view while keeping the amount of conditioned air supplied to the inside of the air conditioning unit constant. Therefore, the flexibility of the layout of the air conditioning unit can be expanded without impairing the air conditioning function.
