Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for a swinging window, which opens/closes a window by swinging a window plate pivotally supported on the upper or lower edge of a window frame upward or downward. In particular, the present invention relates to an opening/closing device having a function of rapidly opening the swinging opening/closing window.

Swinging windows are widely used as high windows that are installed in high places in buildings such as buildings and factories, and also serve as smoke exhaust windows.Such swinging windows are as shown in Figure 1. , a plurality of window frames a are fitted into window holes made through the wall of the building, and a window board with a glass plate C stretched over the lower edge of each window frame a is hinged to the lower edge of each window frame a.
Rod e7X expands and contracts with the elasticity of a compression coil spring! The base end of the support stay d provided with the support stay d is attached to the lower end of the side edge of the window frame a,
The tips of the rods e are connected to the center of the side edges of the window board, and the wire g is passed through the pulleys f provided at both ends of the window frame a and the upper edge of the window board. One end is fixed to the window frame a, and the other end is fixed to the rotating drum of an operating device equipped with a non-reversible clutch. During normal operation, the wire g is wound around the rotating drum under the operation of the non-reversible clutch. By taking the pressure f4 (1), the window is closed while contracting the rod e against the elasticity of the coil spring, and by letting out the wire g from the rotating drum, the window is slowly opened by the stretching action of the rod e, and, In the event of an emergency such as a fire outbreak, a configuration is generally adopted in which the wire g is freed by disabling the irreversible clutch and the window pane is rapidly opened by the extension force of the rod e.

By the way, in a swinging 1-hour opening/closing window with such a configuration, when the window is closed, the support stay d is exposed on the indoor side,
In addition, since the wire g and pulley f are exposed in the same way, their appearance is extremely unsightly, and even if these support stays d, wire g, and pulley f are covered with a cover, etc., they need to be covered separately. Therefore, the number of covers, etc. increases, making it extremely troublesome to install them.Moreover, the cover covering the support stay d is installed in a state that protrudes from the side edge of the window frame a toward the window board. There is a drawback that the light-transmitting area of the window board is narrowed, resulting in insufficient lighting.
Since the extension force of the rod e always acts on the central part of the side edge of the window board, that part curves toward the outdoors, creating a gap +7U between it and the window frame a.

The present invention was completed with the aim of eliminating the above-mentioned drawbacks, and one embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In Figures 2 and 8, a plurality of window frames 1, such as aluminum sash, are fitted horizontally into window holes cut through the wall of the building, and a glass plate 11 is stretched in the center. 2
is freely pivoted to the outside by a hinge 8 at the lower edge of the window frame 1. A mounting member 18 is attached to the bracket 12 fixed to both ends of the lower surface of the upper edge of the window frame 1 with screws.
is supported by a shaft 14 so as to be able to freely swing upward, and a pulley 5 is rotatably supported on this mounting member 13, and is fixed to both ends of the upper edge of the window panel 2 on the indoor side with screws. On the bracket 15, a mounting member 16 is supported by a shaft 17 so as to be freely swingable up and down, and a pulley 6 is also rotatably supported on this mounting member 16. A wire 4 is horizontally routed along the upper edge of the window frame 1 on the indoor side.
The wire 4 is hung on a pulley 5 attached to the window frame 1, and the part that extends from between these pulleys 5 is passed to a pulley 6 attached to the window board 2. One end is equipped with a non-reversible clutch and connected to a rotating drum of an operating device (not shown), and the other end is fixed to the window frame 1 located farthest from the operating device. The above-mentioned irreversible clutch has a mechanism in which the driving force of the rotating drum is transmitted to the wire 4, but conversely, the rotating drum does not rotate due to the movement of the wire 4, and the rotating drum is not rotated. The window plate 2 can be opened and closed only when it is driven, and cannot be opened or closed even if force is applied directly to the window plate 2. This irreversible clutch can be switched between activation and deactivation. .

A horizontal guide rod 21 is fixed to the three brackets 20 fixed by screws to both ends and the center of the lower surface of the upper edge of the window frame 1 described above.
1, a pair of left and right sliding bodies 22 are fitted so as to be freely slidable and rotatable. In addition, a bracket 23 fixed to the center part of the upper edge of the window board 2 on the indoor side with a screw has a
The mounting member 24 is supported by a shaft 25 so as to be freely swingable up and down. A vertical shaft 26 fixed to the mounting member 24 supports short-legged clevises 28 fixed to the respective tips of a pair of left and right rods 27. A long-legged clevis 29 is supported by a bottle 8o that is installed on both the upper and lower surfaces of the left and right sliding bodies 22, respectively.

Further, a compression coil spring 32 is installed between a collar 81 formed at both ends of the guide rod 21 and the left and right sliding bodies 22, and the left and right sliding bodies 22 are attached to the guide rod 21 as shafts. Left and right stoppers 8B for restricting movement toward the center of the direction are fixed at positions 141 equidistant apart from the center.

Next, the operation of the tree embodiment will be explained.

First, as shown by the solid line in FIGS. 2 and 8, the fenestration f
When closing the window plate 2 in the window, rotate the rotating drum of the operating device in the forward direction manually or electrically.
When one end of the wire 4 is wound around a rotating drum, the wire 4 is pulled to the right in FIG. 2, and the part that is fed out between the pulleys 5 to the outside contracts, causing the window plate 2 to turn toward the indoor side. Swing gradually. When the tips of the left and right rods 27 connected to the window plate 2 are pushed by the shaking of the window plate 2,
connected to the proximal end of each rod 27? The moving body 22 moves toward both ends on the guide rod 21 while elastically compressing the compression coil spring 32, and the left and right rods 27 are gradually lowered while reducing the vertical inclination, until the window plate 2 is completely closed. When the rotation of the rotary drum is stopped when the window is closed, the window plate 2 is maintained in the closed state by the action of the irreversible clutch.

At this time, the rod 27, as shown by the chain line in FIG.
is in a straight line position and is located directly below the lower surface of the upper edge of the window frame 1 along with the guide rod 21, and the pulley 5.6 and wire 4, including the rod 27 and the guide rod 21, are Since it is located directly under the lower surface of the upper edge of the frame 1, just attaching one cover to the front of the upper edge of the window board 1 will
The above-mentioned rod 27, horizontal rod 21. The pulley 5.6 and the wire 4 can all be hidden.

Furthermore, when the window is closed, the restoring elastic expansion force of the compressed compression coil spring 82 moves each sliding body 22 in the direction of approaching each other and is biased 1lIJ, which causes the rod 27 to try to close. The tip always presses the window plate 2, but since this pressing force acts on the upper edge of the window plate 2, there is no fear that the central part of the window plate 2 will curve toward the outdoors.

When opening the window plate 2, the rotating drum is reversed and the wire 4 is let out from the rotating drum.
Due to the restoring elastic expansion force of the compression coil spring 32, the left and right sliding bodies 2
2 slowly move toward each other, the left and right rods 27 tilt downward and close, and their tips touch the window plate 2.
The window board 2 is opened by pressing the upper edge of the window.

In the event of a fire or other incident, the window board 2 will be closed to remove smoke.
If it is necessary to quickly open the window from the closed window, the non-reversible clutch is deactivated and the rotating drum is allowed to rotate freely.
Even if it is not, the left and right sliding bodies 22 move at a rapid speed due to the restoring elastic expansion force of the compression coil spring 82 mentioned above, and the rod 27 closes, and the tip of the rod 27 pushes the window plate 2. When the slider 22 is suddenly opened and the slider 22 hits the stopper 8B, the rod 27 can no longer be closed and the opening of the window plate 2 is completed. At this time, the window plate 2 is suddenly stopped, so if the weight of the window plate 2 is large, the impact may break the hinge 3 or break the glass plate 11.In such a case, , Is there a measure to apply a brake to the wire 4 by installing a loosening device on the operating device, etc.? It is necessary to set t to iMf.

In addition, in the above embodiment, the left and right pair σ)
A tension coil spring is installed between the bodies 22, and both ends of the tension coil springs ζ and σ are attached to these sliding bodies 22i, and the sliding bodies 22 are attached to both ends of the guide rod 21 (transfer 1111).
Due to the elastic compression force that accumulates when it is pressed, the mouth and
It also appears to be configured to obtain the pressing force of Sodo 27).

Furthermore, depending on the width dimension of the window plate 2 or the swinging angle, the tip of the rod 27 may be connected to the upper edge of the window plate 2 at a distance. Connect the tip to the WII end of window board 2.

From there, the rod 27 may be directed toward the center of the guide rod 21 and its base end connected to the sliding body 22.

Furthermore, the device of the present invention is applicable not only to outward-folding windows as shown in the above embodiments, but also to windows in which windows are opened by swinging a window plate pivoted to the upper edge of a window frame upwards. It can be applied in the same way.

As specifically explained in the above embodiments, the swinging window opening/closing device of the present invention has a window board hinged to one edge of a window frame and is opened and closed by swinging of the window board. In the movable opening/closing window, a guide rod is arranged along the edge corresponding to the edge of the window frame, and the guide rod is slidably fitted into the guide rod, and the pair of sliding bodies and the free end of the window plate are fitted. are connected by separate rods, and a coil spring is attached to the pair of sliding bodies in a direction along the guide rod, and the elastic force of the coil spring urges the window plate in the direction of opening the window via each of the rods. , the gist is that nine ears are hung on the free end of the window plate to pull it in the fenestration direction against the elasticity of the coil spring, and the window plate is subdivided in the fenestration direction. The rod, the guide rod that supports it, and the wire that pulls the window pane in the closing direction are grouped together at the edge of the window frame corresponding to the free end of the window pane, so that the window pane is in the closed state. In this case, all of these can be hidden with one concealing member, which simplifies installation work and gives a clean appearance. Since the pressing force of the rod due to the restoring force of the spring always acts on the free end of the window board, it is possible to avoid problems such as the vertical center of the window board curving toward the outdoors. play.
