Description

[Detailed description of the invention] This invention consists of horizontally connecting multiple swinging windows that open and close by swinging a shoji that is pivoted on either the upper or lower edge of the window frame. A pair of left and right pulleys was supported on each case, which was supported on the other edge of the window frame so that it could freely swing up and down, and the pulleys were horizontally routed along the other edge of each window frame of a series of swinging opening/closing windows. A wire is hung between each pair of pulleys, and the part that is fed out from between each pair of pulleys is wrapped around a pulley that is pivotally supported at the swinging end of each shoji, and each drawn out part is contracted by pulling the wire in one direction. The present invention relates to an interlocking opening/closing device for swinging windows that closes each swinging window.

In the case of the device configured as described above, especially when closing a window by pulling a wire, each window must be closed at the same time because the farther the window is from the position where the tension is applied, the worse the transmission efficiency is. Instead, the windows close to the position where the tensile force is applied act to close the windows in order, and as clearly shown in Figure 1, adjacent window panels close at different inclinations. Due to the different inclinations of the window panels, cases installed on adjacent window frames also have different inclinations. At this time, assuming that the support shaft of the case and the horizontal part of the wire hung on the pulley inside the case are not on the same line, the horizontal part of the wire routed between the adjacent windows will be equal to the difference in the inclination of the case. is tilted in the vertical direction, and as a result, the case is strained at the support shaft and cannot swing smoothly, resulting in the inconvenience that the window cannot be closed smoothly.

In view of the above-mentioned points, the present invention aims to provide an interlocking opening/closing device for a swinging opening/closing window that can smoothly close the window without straining the case.

Hereinafter, an embodiment in which the present invention is applied to an outward folding window will be described in detail based on the drawings.

FIG. 1 shows the external appearance of the device according to the present invention, in which a wall 1 of a building is provided with a plurality of outward-folding windows 2 arranged in a row in the lateral direction. It consists of a window frame 3 made of aluminum sash or the like fitted into a through hole provided in the window frame 3, and a window plate 5 that can close the window hole 4 defined by the window frame 3. It is pivoted to the window frame 3 via a hinge (not shown) so that it can be freely opened and closed. Further, a support stay 7 having a piston rod 6 elastically expanded and contracted by a compression coil spring is provided, and the end of the piston rod 6 is attached to the window plate 5, and the main body end of the support stay 7 is attached to the window frame 3. The opening force is always applied to the window plate 5 by the support stay 7 when the window is closed. Furthermore, two L-shaped brackets 8 are protruded from the upper edge of each window frame 3 on the indoor side, and a case 9 is attached to each bracket 8 so as to be able to swing freely in the vertical direction. , details thereof will be explained with reference to FIG.

In FIG. 2, the bracket 8 is fitted with a screw 10.
A bearing part 11 is formed at the tip of the window frame 3, and this bearing part 11
A pair of washers 13, 13 are inserted into the through hole 12 provided through the
A support shaft 14 is inserted through the support shaft 14 . The case 9 is made up of a lower case 15 and upper lids 16, 16, and the lower case 15 has a pair of support parts 1 formed with recesses 17, 17 for receiving both ends of the shaft 14.
8 and 18 are provided, and as shown in FIG.
After fitting the bearing parts 11, the upper covers 16, 16 are fixed to the lower case 15 with screws 19, so that the case 9 is supported by the shaft 14 so as to be able to swing freely in the vertical direction. There is. Also, the lower case 1
5 has a pair of shafts 2 on both sides of the support parts 18, 18.
A pair of pulleys 21, 21 are rotatably supported on these shafts 20, 20, and guide grooves 21a, 21a formed on the outer periphery of both pulleys 21, 21 are installed. A tangent line connecting the center circles of is coincident with the center line of the support shaft 14.

Referring again to FIG. 1, two pulleys 22 are installed on the upper edge of each window panel 5 on the indoor side, and these pulleys 22 are axially aligned with respect to the holding member 23, as shown in FIG. The holding member 23 is further supported by a mounting member 26 which is attached to the window plate 5 with screws 25, 25 so as to be freely swingable in the vertical direction by a shaft 27. Moreover, wires 28 connecting each window plate 5 are routed to the series of outward-folding windows 2, 2...
As shown in FIG. 2, this wire 28 is connected to a notch 2 formed on both sides of each case 9, with a wire 28 horizontally routed along the upper edge of each window frame 3 on the indoor side.
9 and 29 and hooked onto the pair of pulleys 21 and 21, and the part that extends outside through another notch 30 formed in the center of the case 9 from between the pulleys 21 and 21 is the pulley on the window plate 5. It spans 22.

At this time, as mentioned above, the pair of pulleys 21,
21 is installed in such a way that the tangent connecting the center circles of the guide grooves 21a and 21a coincides with the center line of the support shaft 14, so that the horizontal portion of the wire 28, as shown in FIG. The cable is arranged so that its axis is on the same line A as the axis of the support shaft 14.

One end of the wire 28 is wound around a drum (not shown) in a wire winding unit 32 via a pulley 31 provided on the side of the window frame 3 on the wall surface 1, and the other end is wound around a drum (not shown) in a wire winding unit 32. It is fixed to frame 3.

In the device of the present invention having the above configuration, in order to close each outward folding window 2 in the open state, the wire 28 is moved to the winding unit 32 by a handle or a drive motor.
This is done by winding the wire 28 around a drum and sequentially contracting the unwinding portion of the wire 28.
As mentioned in the explanation of the prior art, the transmission efficiency of the winding force becomes worse as the distance from the unit 32 increases. Cases 9 installed in adjacent window frames 3 by the difference in inclination of cases 5
will also have different slopes. However, as shown in FIG. 3, since the horizontal portion of the wire 28 is routed so as to be concentric with the support shaft 14 of each case 9, the cases 9 mounted on the adjacent window frames 3 In addition, despite the deviation in the inclinations of the pair of pulleys 21, 21 in the case 9, the horizontal portion of the wire 28 routed between the adjacent folding windows 2 does not tilt, and the case 9 does not twist. There is no fear of being caught. Therefore, the window closing operation by winding the wire 28 can be performed without any problem.

Incidentally, the opening of the outward folding window 2 is performed by releasing the ratchet lock of the drum of the winding unit 32, and under such operation, the opening of the outward folding window 2 is performed by the elastic stretching action of the piston rod 6 of the support stay 7. The window is suddenly opened, but even in this case,
Needless to say, there is no risk that Case 9 will be compromised.

As specifically explained in the above example,
The interlocking opening/closing device for swinging opening/closing windows of the present invention has a bracket fixed to each window frame, each case being pivotally supported by each bracket between each pair of pulleys, and a bracket placed between adjacent swinging opening/closing windows. The main point is that the horizontal part of the wire that is routed is concentric with the support axis of each case, so that the horizontal part of the wire that is routed between adjacent folding windows does not tilt. Since the case attached to the window frame is not twisted by the support shaft, the case swings smoothly and the window board can be closed smoothly.
