Description

[Detailed Description of the Invention] Technical Field The present invention relates to an airtight device for a folding window in which a pair of sliding doors rotatably connected to a window frame are fitted and assembled.

Conventional techniques and problems Conventional air-tight devices for half-fold windows are, for example,
There is a structure described in Publication No. 28291, but in this known structure, an airtight material is placed between the vertical frames on the connection side when the shoji is closed, and the shoji is connected to the window frame through the airtight material when the shoji is closed. Although the structure is such that the airtight material on the vertical stile side and the airtight material on the window frame side do not come into contact with each other, the connection part of the shoji, that is, the upper and lower ends of the shoji stile on the connecting side There are gaps between the parts, and airtightness cannot always be maintained.

Purpose of the Present Invention The present invention was devised for the purpose of eliminating the above-mentioned conventional drawbacks and providing a folding window with excellent airtightness.

Means for Achieving the Object In order to achieve the above-mentioned object, the present invention provides a receiving piece projecting toward the center of the window frame opening around the four circumferences of the indoor end of the window frame, and at the outdoor end of the receiving piece, The shoji is provided with an airtight material whose front end surface on the outside side is located on the same plane along the four circumferences of the window frame, and which are rotatably connected to each other and which are pressed against the receiving piece through the airtight material when closed. An airtight material is provided between the vertical stiles on the connection side and is compressed by the vertical stiles when the shoji is closed, and both upper and lower ends of the airtight material on the vertical side protrude toward the indoor side from the vertical stiles.

Embodiment The drawing shows an embodiment of the airtight device for a folding window according to the present invention, where A is a window frame, and the window frame A includes an upper frame 1a, a lower frame 1b, and a pair of vertical frames 1c, 1c assembled together. A receiving piece 2 is formed at the indoor end of each frame 1a, 1b, and 1c and projects toward the opening center of the window frame A, and a locking groove 3 provided at the outdoor end of the receiving piece 2 is formed. The airtight material 4 is attached, and the tip surfaces 4a of the airtight material 4 attached to each frame 1a, 1b, and 1c are arranged in the same plane along the four circumferences of the window frame A, and are arranged along the inner peripheral edge of the window frame A. A pair of shoji B, B rotatably connected to this window frame A via a connecting member 5 are engaged to open and close freely, and shoji B is connected to an upper stile 6a, a lower stile 6b, and a pair of vertical stile. 6c, 6c' and a glass plate 7 are assembled together, and the connecting member 5 is made up of a connecting member 5a and a guide member 5b that guides the vertical movement of the pulling pieces 8, 8' of the pulling mechanism. Missing circular connecting recesses 9, 9 are provided on opposing surfaces of the member 5a, and a missing circular connecting piece 10 protruding from the vertical stile on the connection side of the shoji B, that is, the inner vertical stile 6c, is engaged with the connecting recess 9. Then, as described above, both the shoji B and B are connected to each other via the connecting member 5, and the indoor side locking groove 11 and the indoor side engaging groove are formed on the opposing sides of the shoji B when the inner vertical stile 6c is closed. Stop groove 1
An airtight groove 12 is provided vertically with a width narrower than 1, and the indoor side locking groove 11 is in pressure contact with the guide member 5b of the connecting member 5 when the shoji is closed, and also protrudes toward the indoor side from the inner vertical stile 6c. In addition, in the indoor locking groove 12, the drainers 4'' provided on each shoji B, B overlap in the indoor-outdoor direction when the shoji is closed. be.

The pulling mechanism includes the pulling pieces 8, 8 at the tips of connecting rods 14, 14' that move vertically along the guide member 5b of the connecting member 5 by operating a pulling handle 13 attached to the connecting member 5. ′ is attached, and the central pulling pieces 8, 8′ engage with each other.
5' are provided on the upper frame 1a and the lower frame 1b of the window frame A, and a side drawing sub-member 16 that assists this drawing mechanism is attached to the vertical frame 1c of the window frame A, and the side drawing sub-member 16 is attached to the vertical frame 1c of the window frame A. A locking piece 24 that locks onto the material 16 is vertically provided at the outdoor end of the outer stile 6c'.

In addition, in the embodiment, selection handles 17, 17 are rotatably attached to the outer vertical frames 6c', 6c' of the shoji B, and the upper and lower connecting rods 18, 18 are vertically moved by the selection handles 17. Engagement holes 19, 1 provided in the upper window frame 1a and the lower window frame 1b at the tips of the
Attach the hand selection shafts 20, 20' for disengaging 9',
Shoji B and B can be opened and closed in either direction.

In the second embodiment shown in FIG. 7, one shoji is equipped with a pulling mechanism, and a connecting member 5' is provided with a cylindrical connecting piece 5'a, which is engaged with the connecting piece 5'a. A connecting piece 10' is provided on the inner stile 6c of the shoji, and the airtight material 4' that protrudes toward the indoor side from the inner stile 6c presses against each other when the shoji is closed, thereby creating a connection between the shoji B and B. The structure is designed to provide airtightness. In this second embodiment, the airtight material 4' is arranged biased towards one shoji side, but it is of course possible to arrange it in the center between both shojis; Similarly to the above, both upper and lower ends of the airtight material 4' are attached to the upper and lower window frames 1.
The airtightness is maintained completely even in the central part of the shoji by press-contacting the airtight material 4 attached to the shoji.

Therefore, it is desirable that the airtight material 4' protrude by an appropriate amount in the direction of the window frame A, that is, with respect to the airtight material 4 of the window frame A, so that the pressure contact with the airtight material 4 can be performed more reliably.

21 shown in the figure is an upper guide rail 2 provided on the window upper frame 1a.
2 is a hanging wheel that rolls and is attached to the shoji B side, and 23 is a piece that is attached to the shoji B side and slides into the lower guide rail 22' provided on the window lower frame 1b.

Effects of the present invention As mentioned above, the present invention is provided with the airtight material on the receiving piece of the window frame so that its tip surface is located on the same plane along the four circumferences of the window frame, so that the half-folded shoji can be closed. To ensure airtightness between a shoji and a window frame at times.

In addition, the airtightness between the shoji can be ensured, and since the airtight material provided between the shojis protrudes toward the room from the vertical stile, when the shoji is closed, the airtight material on the vertical stile side is placed on the window frame side. Therefore, the gap created between the vertical stile and the window frame on the side where the shoji is connected can be closed, and the airtightness of this area can be maintained. Overall, by applying this invention, an excellent airtight function can be achieved. Therefore, it is possible to provide a folding window.
