Description

[Detailed Description of the Invention] [Industrial field of application] The present invention utilizes an internal space of a partition type panel standing upright on the floor surface of an office of a building or the like, and is used for air conditioning such as cooling and heating in a room. The present invention relates to a structure of a partition including an air conditioning blowout unit that supplies adjusted air.

[Conventional technology]

In offices in buildings these days, so-called office equipment such as computers and word processors are often installed, so an appropriate underfloor space is formed between the concrete floor base of the room and the floorboard above it. As described above, a free-access floor structure as a double-floor device is adopted, and wiring for OA equipment is often provided in this underfloor space.

Further, in recent buildings, it is common practice to provide an air conditioning (air conditioning) system so as to keep the temperature and humidity in each room substantially constant throughout the year.

In this case, as disclosed in Japanese Unexamined Utility Model Publication No. 62-99751, the air conditioned by the air conditioning system (hereinafter referred to as regulated air) is guided to the underfloor space, and the free access floor is appropriately placed. It is proposed that the air be introduced into the room from the air outlet.

In such a case, depending on the layout of furniture such as a desk or a partition panel (partition) to be installed indoors, the furniture may block the air outlet of the free access floor or adjust the bend angle to the required location. Since there is a problem that air does not reach, one of the applicants has previously proposed in Japanese Patent Application No. 2-53941 that the interior of furniture such as a partition type panel is formed into a hollow ventilation passage and the lower end of the furniture is It has been proposed to open the air outlet of the free access floor so as to cover it from above, and to provide an outlet for releasing the adjusted air into the room on the side surface of the furniture.

In addition, in Japanese Utility Model Laid-Open No. 2-9612, partitions that are erected so as to connect from the floor surface to the ceiling are connected to both left and right ends of front and back surface mounting panels by columns on both left and right sides of the vertical direction. There has been proposed a configuration in which an inside surrounded by a person is formed as a ventilation path through which adjusted air can pass vertically, and an adjusted air blowing unit is provided at each of upper and lower portions of the wide surface of one of the mounting panels.

By the way, in a partition partition, the left and right ends of a rectangular hollow frame, which is made by tensioning the front and back panels on the front and back sides, are attached to a pair of left and right adjuster columns to stand from the floor. Therefore, there is an appropriate space between the lower side of the hollow frame in the partition and the floor surface. Therefore, in order to use the inside of the hollow frame in the partition of this kind as a ventilation path for the adjusted air and to introduce the adjusted air from the floor side, the intake air for introducing the adjusted air is introduced into the space location. It may be preferable to provide a duct.

[Problems to be solved by the device]

However, when arranging the lower blowing unit between the intake duct and the lower side of the hollow frame, the lower blowing unit frame has to be interposed, and in particular, the lower blowing unit frame has an opening / closing plate. When installing so that it can move to the left and right, while simplifying the structure of the frame for the lower blowing unit, it is easy to install the opening and closing plate,
Moreover, it is necessary to prevent the adjusted air from leaking out of the lower blow-out unit frame other than the blow-out port.

The present invention aims to provide a partition with a blowing unit that solves these problems.

[Means for Solving the Problems]

In order to achieve this purpose, the present invention provides a pair of left and right end pillars,
A main frame body having a substantially rectangular shape in a front view is constituted by a horizontal beam reinforcing member having upper and lower portions laterally connected and a through hole for adjusting air passage being bored, and front and back panels of the main frame body on both front and back surfaces. Is a partition of a partition type in which a hollow air passage is formed by fixing the upper side beam reinforcement member to the upper side of at least one of the upper and lower wide sides of the front panel. While providing an upper air-conditioning blowout unit along, between the lower end edge of the one of the cover panels and the inner surface of the other cover panel extending below the lower end edge,
The frame body for the lower blowing unit, which is released in the left and right side ends of the cover panel and has an opening / closing plate movable along the upper and lower rails extending along the lower edge of the one cover panel, is fixed, The frame body is provided with a through hole communicating with the ventilation passage, and the lower end of the frame body is provided with a vertically open intake duct for introducing regulated air, while the left and right side ends of the frame body are released. The end cap is provided so as to be detachably inserted into the section.

[Operation and effect of device]

Thus, the lower blowing unit of the present invention is
Depending on the degree of movement of the open / close plate that can move left and right along the wide surface of the cover panel in the partition, the amount of the regulated air blown to the outside can be adjusted up or down, or a closed state in which no blown air is blown out can be achieved. The frame for the lower blowing unit is fixedly arranged between the lower end edge of one of the cover panels and the inner surface of the other cover panel extending below the lower end, and the frame is attached to the cover. Upper and lower rail portions are provided which are released toward both left and right ends of the panel and which extend along the lower edge of the one of the mounting panels and on which the opening / closing plate is mounted.

Therefore, with one of the end caps for closing the left and right side end release portions of the frame body removed in advance, the opening and closing plate is attached to the rail portion of the frame body from the left or right end portion of the partition. After inserting, by inserting the end caps again, the rail and the left and right end release parts of the frame can be closed very easily, and the adjusted air from the intake duct includes the left and right ends of the rail. There is no leakage from the left and right open ends.

In this way, if the structure of the frame for the lower blowing unit is formed so that both left and right ends including the left and right ends of the rail portion are open, it is more flexible than forming a box shape that also closes the left and right ends of the frame. The formation work is extremely easy, and the production cost is low.

Further, as described above, the work of inserting the opening / closing plate into the rail portion having the both ends opened is extremely easy. Moreover, after the opening and closing plate is installed, if the end caps are used to block the left and right ends of the frame, the adjustment air can be easily prevented from leaking from any part of the lower blowing unit frame other than the outlet. It has the effect of being able to do it.

Moreover, since the frame body for the blowing unit is arranged and fixed between the lower end edge of one of the cover panels and the inner surface of the other cover panel extending below the lower end edge, the rigidity of the partition by the addition of the frame body, As a result, the strength can be increased.
