1 shows an embodiment of a folding sash according to the present invention. FIG. 1 is an enlarged sectional view of a main part in an open state, FIG. 2 is a transverse sectional view, and FIG. FIG.

A folding sash according to an embodiment includes a pair of folding sash structural units A, A composed of a pair of sashes 1, 1 'rotatably connected to each other and an indoor side of the structural units A, A. The arranged screen doors C, C are assembled to the window frame B, and the entire area of the opening of the window frame B is closed by the screen doors C, C so that the insect repellent effect can be achieved. The sash is fully open and offers a wide field of view.

In the folding sash structural unit A, the pair of sashes 1 and 1 ′ are rotatably connected to each other via a connecting rod 2 equipped with a pulling mechanism that also serves as a lock (not shown), and a window frame B is formed. The vertical frame 4 'of one of the sliding doors 1' on the side of the vertical frame 3c to be configured
c is connected to the vertical frame 3c via an assembling hinge 5 and connected to the vertical frame 4c of the other one of the sliding doors 1 via a connecting hinge 6 to an operation frame 7
And a hanging car (not shown) protruding from the upper end of the operation frame 7
Are mounted on a guide rail (not shown) provided on an upper frame constituting the window frame B together with the vertical frames 3c, 3c and the lower frame so as to be able to travel freely.

The operation frame 7 is provided with a part 7a which is overlapped in the indoor and outdoor directions when the sash is closed at one outdoor end of the hollow main body 7A, and a locking groove 7b at the indoor end.
b, the elastic watertight members 8 that are in close contact with each other when the shoji is closed are fixed, while the connection hinge 6 is arranged on the outdoor side of the other one surface of the hollow main body 7A opposite to the one surface as described above. Connected to the vertical frame 4c, an L-shaped handle piece 9 is protruded on the indoor side, and when the shoji is closed, the grip piece 9 has a fingertip insertion gap 10 in the vertical frame 4c in the indoor and outdoor directions. So that they overlap.

The handle piece 9 is provided above and below the operation frame, and comprises a projecting piece 9a perpendicular to the opening surface and a projecting piece 9b parallel to the opening surface. Then, as shown in FIG. 2, for example, when only the right sash component unit A is opened, the tip of the screen door C is overlapped with the protruding piece 9b surface of the handle piece 9 of the left sash component unit A, for example, a mohair strip. And the handle piece 9 has a configuration in which the extension length of the protruding piece 9b is longer than that of the protruding piece 9a.

This is based on the following reasons.

Since the handle piece 9 is provided above and below the operation frame, if the extension length of the protruding piece 9a is increased,
Possibility of catching feet in the lower part. In addition, the distance between the sash and the screen door is widened, and the sash is expected to be larger than the thickness of the wall on which the sash is to be mounted, and it is necessary to travel the sash frame inside or outside the room. Spoil. On the other hand, if the extension length of the protruding piece 9b is shortened, it becomes easier to insert a finger between the vertical frame and the operation frame, and the danger of pinching increases, so the extension length of the protruding piece 9b is increased. Even when the handle piece 9 is hung, the vertical frame and the projecting piece 9
It is possible to prevent the fingers from being caught by configuring the device so that the finger can be accommodated inside b. That is, in the configuration in which the handle piece 9 is provided leaving a predetermined space from the vertical frame and covers the close contact portion between the vertical frame and the operation frame, the extension length of the projecting piece 9b is longer than the projecting piece 9a. By doing so, it was possible to prevent the foot from being caught and pinched, and to reduce the prospect of the sash.

An elastic watertight material 8c is provided on the indoor end side of the operation frame 7 opposite to the vertical frame 4c, and a projecting piece 13 which is pressed against the watertight material 8c when the sash is closed. A vertical contact surface 13a of the protruding piece 13 that is in contact with the watertight material 8c is tapered so as to gradually project from the indoor side to the outdoor side. The contact surface a with the piece is tapered in the opposite direction to the contact surface 13a.

When each of the structural units A, A is placed in the window frame B and the operating handle 11 is operated to draw the sashes 1, 1 'constituting the unit A in the indoor direction, the sash is closed. The connecting rod 2 and the sliding doors 1, 1 ', 1' assembling frames 4c ', 4'c' are arranged on the elastic watertight material 8a provided on the four circumferences of the window frame B in the state. Combination frame 4c
', 4'c' side, elastic watertight material 8b, watertight material 8c fixed to operation frame 7 side and operation frame 7 interposed between operation frame 7 and vertical frame 4c of one of the sliding doors 1 and operation. The water-tight members 8 arranged between the frames 7, 7 are pressed against each other, so that a water-tight closed state of the sash is obtained.

In this state, the operating handle 11 attached to the indoor side of the connecting rod 2 is operated to release the locking portion of the pulling mechanism from the upper frame and the lower frame, and to move the operating handle in the outdoor direction. When pressed, one of the sliding doors 1 ′ rotates in the outdoor direction around the axis of the assembly hinge 5, and the other sliding door 1 is moved in the outdoor direction by moving the operating handle 11, that is, the connecting rod 2 in the outdoor direction. 2, the operation frame 7 is pulled while rotating about the axis of the connection hinge 6, and the operation frame 7 is moved in the direction of the vertical frame 3c along the upper frame by the hanging wheel rolling on the guide rail. Then, the sliding door is moved, and the sliding door is opened. If necessary, the sliding door 12c of the screen door C is moved in the direction of being separated from the fixed frame 12'c along the upper frame. Combine 12c with each other and use net sheet 12A. Therefore, a comfortable ventilation state can be obtained by closing between the indoor and outdoor areas.

After the movable frame 12c of the screen door C is returned to the original position and the screen door C is closed, the handle piece 9 provided on the operation frame 7 is pinched with a fingertip to close the shoji, and then the operation handle 11 is closed.
By operating to lock the locking piece to the upper frame etc.,
The closed state of the shoji can be obtained again.

The present invention can be applied to a folding sash provided with a pair of sliding doors. In this case, in the embodiment, the operation frames are adjacent to each other, whereas the operation frame is adjacent to the vertical frame. Will take the form of

[0017]

Since the present invention has the configuration as described above,
At the time of shoji closing operation, at least due to the presence of the handle piece,
Since the closing operation is performed by touching the handle piece with the fingertip without touching the vertical frame, it is possible to provide a folding sash in which the fingertip is not likely to be pinched between the vertical frame and the operation frame.

Further, the contact between the protruding piece (metal) and the elastic watertight material ensures the watertightness between the vertical frame and the operation frame, and the tapered shape allows the mutual contact to be performed without difficulty. Thus, damage of the watertight material due to unnatural elastic deformation can be prevented.
