Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an airtight device for a window that can be opened or folded inside.

[Prior art]

As an airtight device for windows that can be opened inward and collapsed, for example,
The device described in FIG. 2 of 59-84192 is generally known. According to the invention, an indoor side sealing material, an outdoor side sealing material and an intermediate sealing material are interposed between a window frame and a shoji frame. Airtightness is maintained in multiple stages by a plurality of sealing materials to prevent rainwater from entering.

[Problems to be solved by this device]

The fin piece of the sealing material needs to have followability in order to prevent the airtight performance from being deteriorated even when positive and negative wind pressure loads are applied. Therefore, it is conceivable to elongate the fin pieces or to increase the elastic force of the fin pieces in order to give the fin pieces followability. However, if the fin piece is made longer like the former, it will sag and the airtightness will decrease, and in the latter case the sealing material itself will have to be made large and it will be very difficult to manufacture, and if the elastic force is strong it will cause shoji. A large force is required to close it, which causes a problem that it cannot be easily closed.

[Means for solving problems]

The airtight device for a window according to the present invention comprises an upper frame 1, left and right vertical frames 2,
2, a window frame A formed by framing the lower frame 3 and an outdoor side sealing material 6, an indoor side sealing material 22 and an indoor and outdoor sealing material 6 between shoji B arranged in the window frame A, It is composed of an intermediate sealing material C mounted between 22 and the intermediate sealing material C is composed of a first sealing material 11 and a second sealing material 25 having fins 14 and 26 respectively, and the first sealing material 11 is a window frame A. Attach to fin
14 is brought into contact with an abutment piece 23 provided in the shoji B direction from the outside of the room, and the second seal member 25 is attached to the shoji B so that the fin piece 26 is attached to the projecting piece 8 provided in the window frame A finding direction. It abuts from the inside.

Since the positive wind pressure load acting on the shoji screen is received by the first seal material and the negative wind pressure load is received by the second seal material, airtightness is not impaired.

A fin piece 14 projects from the inside toward the inside.

In the figure, B is a shoji, which is a top frame 15, left and right vertical frames 16,16.
And the lower frame 17 is frame-shaped. Each of the frames 15, 16, 17 is made up of an inner frame 15a, 16a, 17a and an outer frame 15b, 16b, 17b, and each frame is formed in a square shape and can be opened and closed by a hinge. Glass fitting grooves 18 are formed on the inner peripheral sides of the inner frames 15a, 16a, 17a and on the inner peripheral sides of the outer frames 15b, 16b, 17b, and the inner edges are fitted into the glass fitting grooves 18. Glass plates 19 and 19 are attached respectively.

The inner side surfaces of the inner frames 15a, 16a, 17a are flush with each other, and a projecting piece 20 projecting in the outer peripheral direction of the shoji B framed in a rectangular shape is provided in a protruding manner. A lip groove 21 continuous in the longitudinal direction is formed on the outdoor side surface of the overhanging piece 20, and an indoor seal member 22 made of synthetic rubber or the like is attached to the lip groove 21.
The tip of the indoor-side sealing material 22 is projected toward the outer peripheral direction of the shoji B mounted in a rectangular shape.

On the outer peripheral side surface of the shoji B framed in a rectangular shape of each of the outer frames 15b, 16b, 17b, an abutment piece 23 and a mounting piece 24 project in parallel in the middle of the indoor / outdoor width direction at a slight distance. The tip of the mounting piece 24 is bent toward the indoor side. A second seal member 25 is attached between the contact piece 23 and the attachment piece 24. The end of the second sealing member 25 is connected to the fin 26, and the shoji B is framed in a square shape.
Is projected in the outer peripheral direction. A ridge 27 is formed continuously on the inner side surface of the second seal member 25 in the longitudinal direction, and is brought into contact with the mounting piece 24 for positioning.

When the shoji B is closed in the inwardly openable and inclinable window having the above-mentioned configuration, the tip of the fin piece 14 of the first sealing material 11 attached to each frame 1, 2, 3 is located at the outer periphery of the shoji B. The abutment piece 23 provided in the finding direction is brought into contact with the outer side surface of the door, and each frame 1 of the shoji B is attached.
The fin pieces 26 of the second sealing material 25 attached to 5, 16, 17 are
The window piece A formed in 1, 2, 3 is brought into contact with the indoor side surface of the projecting piece 8 facing in the finding direction. At this time, the contact piece 23 formed on the outer circumference of the shoji B and the tip of the projecting piece 8 formed on the inner circumference of the window frame A are positioned on substantially the same plane. The first seal material 11 and the second seal material 25 as described above constitute the intermediate seal material C.
