Description

The present invention relates to a natural ventilation device provided for ventilating the inside of a building such as an apartment house or an office building by utilizing natural wind.

In many buildings such as office buildings, windows cannot be opened and closed, and forced ventilation with air conditioning equipment was adopted accordingly. In such a forced ventilation method, there is a risk that the operating cost of the air conditioning equipment is high and the ventilation becomes insufficient due to uneven air conditioning. As a countermeasure for this, for example, as shown in Patent Document 1, a natural ventilation device using natural wind has been proposed.

In the natural ventilation device of Patent Document 1, a frame of a housing in which an opening connecting to the inside and outside of the building is formed on the lower surface, and a large number of slits (vent holes) are provided while covering the upper opening of the frame. It has an upper plate (face cover), a closing member (acting member) that opens and closes an opening (passage) on the lower surface of the frame, and an operating unit that moves the closing member in the vertical direction. The opening on the lower surface of the frame is opened to ventilate the frame by raising the frame and moving it laterally.

WO2009 / 069525

In order to improve the air permeability, it is desired that no obstacle intervenes between the opening (passage) on the lower surface of the frame of the housing and the slit of the upper plate, and in the natural ventilation device of Patent Document 1, the closing member is raised. Breathability is enhanced by moving it laterally as well as by letting it move. However, in the natural ventilation device of Patent Document 1, the cam surface of the housing that guides the closing member (see FIG. 4 of Patent Document 1) is short in the vertical direction, and the closing member is moved to the cam surface during the movement of the closing member. Depart from. Therefore, there is a possibility that the closing member cannot be reliably guided when closing the opening on the lower surface of the frame.

An object of the present invention is to solve such an inconvenience, that is, a natural ventilation device that can maintain high air permeability and can surely guide an operating member to the opening when closing the opening of the frame. Is to provide.

It has an actuating member 5 for opening and closing and a driving means for opening and closing the passage 2 by driving and moving the actuating member 5, and horizontally guides the actuating member 5 to move in the front-rear and lateral directions. The guide plate 13 and the upper and lower guide plates 14 for guiding the vertical movement of the actuating member 5 are arranged on the frame 4, and the actuating member 5 is driven by the actuating member 5 in a state where the through hole 2 is closed. When the actuating member 5 is moved forward along the vertical guide plate 14, the operating member 5 moves upward along the vertical guide plate 13 and laterally along the horizontal guide plate 13 to open the through hole 2 and open the through port 2. When the actuating member 5 is retracted by the driving means, the actuating member 5 moves downward along the upper and lower guide plates 14 and laterally along the horizontal guide plate 13 to close the through hole 2. And.

The natural wind here may include outside air as long as it contains no wind. The through port 2 includes a case where only one is formed and a case where a plurality of through openings 2 are formed.

Specifically, the horizontal guide plate 13 has a guide hole 16 extending in the front-rear direction in a state of being tilted in the left-right direction, and a pin member 17 that stands upright on the upper surface of the operating member 5 is loosely fitted in the guide hole 16. By making the actuating member 5, the actuating member 5 is guided laterally along the guide hole 16 of the horizontal guide plate 13, and the upper and lower guide plates 14 have a guide groove 18 extending in the lateral direction on the inner surface side thereof. The guide groove 18 is formed of an upper horizontal portion 18a extending in the left-right direction, a lower horizontal portion 18b extending in the left-right direction, and an inclined portion 18c connecting the upper and lower horizontal portions 18a and 18b. An end portion of a support bar 20 supported in a horizontal position is loosely fitted in the guide groove 18 on the upper surface of the actuating member 5, and the actuating member 5 moves in the front-rear direction with respect to the support bar 20. When the actuating member 5 is advanced while the actuating member 5 is closed by the actuating member 5, the actuating member 5 moves upward along the guide groove 18 of the upper and lower guide plates 14. When the actuating member 5 is retracted by the driving means while moving and moving in the front-rear direction along the support bar 20 and the through hole 2 is open, the actuating member 5 is moved along the guide groove 18 of the upper and lower guide plates 14. It moves downward and moves forward and backward along the support bar 20.

In the natural ventilation device 1 of the present invention, when the vent 2 of the frame 4 is opened for ventilation, the actuating member 5 moves not only in the vertical direction but also in the lateral direction, so that the actuating member 5 moves through the vent of the frame 4. It is less likely to interfere with the ventilation between the 2 and the ventilation hole 8 of the face cover 7, and the ventilation can be improved by that amount. Moreover, when the through hole 2 of the frame 4 is closed, the operating member 5 is surely guided to the through port 2 of the frame 4 by the horizontal guide plate 13 and the upper and lower guide plates 14.
