Description

[Detailed description of the invention] This invention relates to a ventilation device installed on the upper frame of a shoji screen. If the door of a ventilation system installed on the upper frame is placed on the outside, in order to widen the door opening, it is necessary to largely displace the operating lever directly fixed to the door. Furthermore, due to its location, ventilation doors are often forgotten to close, and rainwater may directly hit the room during strong winds and rain. Also, the door is visible from the outside and does not look good.

The purpose of this invention is to provide a ventilation door in a door-type ventilation system that has a short operating distance and prevents rainwater from entering.

In this invention, a ventilation door is provided within the upper frame of the opening, and a perforated plate is provided on the outside.

This will be explained below with reference to the drawings. In the interior views of Figures 1 and 2, A is the opening frame of the building, B is the inner shoji, C is the outer shoji, 1 is the upper member of the upper frame,
2 is a lower member of the upper frame, 3 is a side member constituted by an extension of the vertical frame, and 4 in FIG. 2 is a ventilation hole provided between them. If the opening width is large, use the first
As shown in the figure, a vertical member 5 is provided to divide the opening into a plurality of ventilation holes 4. 6 is an operating lever. The appearance of the area surrounded by a circle in FIG. 2 is as shown in FIG. 3.

4 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 5 is a horizontal sectional view of the ventilation port 4 in FIG.
The ventilation door 7 has one side of a hinge 8 that is perpendicular to one end fixed in the upper frame of the ventilation opening 4, and a pin 9 is driven into and fixed to the other side of the hinge 8, and the pin 9 moves in the axial direction to the vertical member 5. It can be inserted and pivoted freely. The other end of the ventilation door 7 is fixed to one side of an operating lever 6 that also serves as a right-angled hinge, and the operating lever 6 is attached to a vertical member 1 that fits inside the side member 3 and abuts the upper member 1 and the lower member 2.
It is fixed to a pin 11 which is pivotally attached to the shaft 0 so as to be movable in the axial direction. Gaskets 12 and 13 are fitted into T-grooves of the vertical members 5 and 10, as shown in FIG. 5, and their tops press against the side surfaces of the door 7. T-grooves are cut on the inner and outer surfaces of the upper and lower edges of the door 7, and gaskets 14 and 15 are fitted into them to press the upper and lower members 1 and 2 to maintain airtightness. Grooves 16 and 17 are provided on the outer sides of the upper and lower members 1 and 2, into which a perforated plate 18 is inserted, and the sides of the groove 16 are locked with light pressure by the cutout and extruded portions 18a. The perforated plate 18 is provided with a large number of pores to prevent insects and provide sufficient ventilation.

To open the ventilation door 7, pull the operating lever 6 downward, and the ventilation door will rotate around the pins 9 and 11 as shown by the two-dot chain line in FIG. Press to lock. When the ventilation port 4 is in a high position, the upper member 1 directly above the operating lever 6
Fix the ring 19 to the ring 19, insert the string 20 to the end of the operating lever 6, tie the string 21 directly to the end of the lever 6, and pull the string 20 to connect the operating lever 6 through the ring 19. is pulled up to close the ventilation door 7, and by pulling the string 21, the operation lever 6 is pulled down to open the ventilation door 7. When the ventilation door 7 is in the open position, the pins 9 and 11 that pivot the ventilation door 7 are offset from the flat plate portion of the ventilation door 7, so that the upper edge of the ventilation door 7 is at a higher position than the edge 1a of the upper member. The lower edge of the ventilation door 7 is approximately horizontal to the upper end of the vertical step 2a of the lower member, and its movement is restrained by the perforated plate 18.

As described above, according to this invention, the ventilation door is pivoted to the vertical member of the ventilation port so as to be movable in the axial direction, and both ends of the ventilation door are held down by the gaskets provided on the vertical member, so that both sides of the ventilation door are Pressure is applied evenly and the airtightness is not uneven. There is little movement of the operating lever, and the ventilation door is locked with a gasket, so there is no need for special installation. According to the embodiment of this invention, when rainwater passes through the perforated plate during strong winds and rain, its energy is reduced and it enters the upper frame, bypassing the upper edge of the ventilation door or being stopped by the vertical step of the lower member. Rainwater will not enter the room if the ventilation door is left open. Since it uses a perforated plate, it is durable and has a good design effect.
