DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a folding sash from being pinched with at least one pair of sliding doors rotatably connected.

[0002]

2. Description of the Related Art An operation frame moving along an upper frame or a lower frame is hinged to a vertical frame opposite to the above-mentioned sliding frame of a sliding screen which is rotatably connected to another adjacent sliding screen in the sliding frame. A folding sash having a structure in which a handle piece that overlaps the vertical frame in the indoor and outdoor directions when the sash is closed is provided at the tip of the arm piece protruding from the operation frame, for example, in Utility Model Registration No. 25.
It is publicly known as described in Japanese Patent No. 55455.

[0003] In the folding sash, when closing the shoji, the operation frame is moved along the upper frame or the lower frame, and the shoji which is arranged in a direction crossing the moving direction is moved to the vertical frame and the operation frame. It is necessary to rotate the vertical stile at the hinged part, that is, to displace the vertical stile so as to be flush with the operation stile. During this displacement (closing) operation, a fingertip is sandwiched between the vertical stile and the operation stile. May be caught.

[0004] Therefore, in order to prevent this, a handle piece used as a handle at the time of the displacement operation is provided at the tip of the arm piece which has a large amount of protrusion from the operation frame, and a finger is placed between the handle piece and the operation frame. There is a large fingertip insertion gap that is not pinched.

[0005]

In the prior art, the insertion gap must be made wider than necessary in order to ensure that the fingertip is not pinched between the operation frame and the vertical frame. For this reason, drawbacks of the folding sash, such as the handle piece protruding more than necessary from the shoji (operation frame) and the expected size of the window frame must be increased, and the appearance appearance is not good, etc. are exposed. I do.

The present invention has been made for the purpose of eliminating such disadvantages of the prior art.

[0007]

SUMMARY OF THE INVENTION An operating frame that moves along an upper frame or a lower frame on a vertical frame facing the above-mentioned sliding frame of a sliding door that is rotatably connected to another adjacent sliding door in the sliding frame. At the tip of the arm piece protruding from the operation frame, and at the folding sash protruding a handle piece overlapping the vertical frame indoor and outside when the shoji is closed, a fingertip is applied to the arm piece. And a shielding part protruding in parallel with the handle part with an insertion gap.

FIG. 3 is a cross-sectional view of the main part of the present invention when the shoji is opened, and FIG. 4 is a perspective cross-sectional view of the shielding piece.

The folding sash of the embodiment is constructed by assembling a pair of folding sash structural units A, A composed of a pair of sashes 1, 1 'rotatably connected to each other to a window frame B.

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 which also serves as a lock (not shown). 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 has a portion 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. Along with the vertical frame 4c, an arm piece 9 is protruded on the indoor side, and a handle piece 10 that overlaps with the vertical frame 4 in the indoor and outdoor directions when the shoji is closed at the tip of the arm piece 9 is provided. And a shielding piece 11 parallel to the handle piece 10 is provided at the base of the arm piece 9 with an insertion gap 12 at the fingertip.

The shielding piece 11 is composed of a main body 11a and a mounting part 11b.
A main part 11a is protruded from the arm piece 9 in such a manner that the mounting part 11b is slidably fitted on the arm part 3.
a is provided with a curved surface along a rotation locus about the axis of the connecting hinge 6 of the sliding door 1, that is, the vertical frame 4 c, so that an insertion gap 12 sufficient to insert a fingertip with the handle piece 10 is formed. It is.

The folding sash according to the embodiment, when the operating handle 14 is operated to draw the sashes 1, 1 'constituting the unit A in the indoor direction, the sash is closed and the window frame is closed. In the elastic watertight material installed on the four circumferences of B,
An elastic watertight material fixed to the side of the combination frames 4c ', 4'c' so as to be disposed between the connecting rod 2 and the shoji 1, 1 'combination frames 4c', 4'c '; The watertight material fixed to the operation frame 7 side so as to be interposed in the vertical frame 4c of one of the sliding doors 1 and the watertight material arranged between the operation frames 7 and 7 are pressed against each other to form a watertight body. A sash closure condition is obtained.

In this state, the operating handle attached to the indoor side of the connecting rod 2 is operated to release the engaging portion of the pulling mechanism from the upper frame and the lower frame, and press the operating handle in the outdoor direction. Then, one of the sliding doors 1 'is assembled with the hinge 5
, While the other handle 1 is pulled by the connecting rod 2 by the movement of the operating handle, that is, the connecting rod 2 in the outdoor direction, about the axis of the connecting hinge 6. Pulling the operation frame 7 while rotating, 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, and the shoji is opened.

Then, the handle piece 10 provided on the operation frame 7 is pinched by a fingertip to close the shoji, and then the operating handle 14 is operated to draw the shoji in the indoor direction, thereby obtaining a closed state of the shoji again. Insert the fingertip into the gap 1
When the user grips the handle piece 10 by inserting it into the
To the direction between the vertical frame 4c and the vertical frame 4c.
1 makes this feel because of the presence of
The closing operation can be performed without being caught between the members 4c.

The closer the shielding piece 11 is to the base of the arm piece 9, that is, the closer to the operation frame 7 (or the vertical frame 4c), the more
The insertion gap 12 can be widened, and the amount of protrusion of the arm piece 9 can be reduced.

Further, the tip of the shielding piece 11 (with the arm piece 9 as a base) is located at a position at which the tip of the shielding piece 11 (with the arm piece 9 as a base) overlaps the indoor and outdoor directions. This arrangement is effective in preventing finger pinching, but if the fingertip is inevitably in contact with the insertion gap 12 when it is inserted into the insertion gap 12, it is possible to call attention at least by touching the fingertip. The effects of the present invention can be expected.

The shielding piece 11 may be made of an elastic piece. In this case, since the elastic deformation of the shielding piece 11 can be utilized, the width of the insertion gap 12 can be reduced.

In the embodiment, the present invention is applied to a double-sided folding sash in which the operation frames 7, 7 are engaged with each other. The present invention can be applied to a folding sash, that is, the present invention can be applied to a sash having a pair of sashes that are overlapped and folded when opened.

[0020]
