Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for interlockingly opening or closing each window plate of a plurality of swinging opening/closing windows installed in a high place in a building.

Conventional technology One of the high windows installed in a high place of a building for smoke removal and lighting, the upper or lower edge of the window plate is screwed to the edge of the corresponding window frame, and the window plate swings. It is known that a plurality of swinging windows that open and close are lined up horizontally and the window panels of each swinging window are linked to open and close. In order to open and close the window, a biasing device such as a telescopic stay, in which a rod inserted into a cylinder is biased in the extension direction by the elasticity of a coil spring, is installed between the corresponding side edges of the window frame and window plate. At the same time as applying force in the direction of window opening, wires are sequentially passed through pulleys installed on each window frame and window plate, one end of which is connected to a rotating drum in an operation box located in a low part of the building, and the other end is It is fixed to the farthest window frame, and by winding the wire around the rotating drum, each window pane is closed against the biasing force, and by letting out the wire from the rotating drum, each window pane is opened using the biasing force. is common.

Problems that the invention aims to solve However, in such opening/closing devices, wires are sequentially stretched between each window frame and window plate.
When the window board is opened, the wires are exposed between the window frame and the window board, which is not only aesthetically undesirable but also prone to rust, etc. Also, a biasing device is required, and it is difficult to open and close the window board in a balanced manner. It is necessary to install a device on both side edges of each swing opening/closing window in order to prevent the hinge from being pried.
The structure was complicated and there were defects that increased costs.

The present invention has been developed in view of the above-mentioned points, and has a simple structure with a clean appearance, and a swinging opening/closing window opening/closing device that allows each window panel to be opened and closed in conjunction with each other. The purpose is to provide the following.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

1 is a swinging opening/closing window, and on the upper edge of the window frame 2,
It has a structure in which a window plate 3 on which a glass plate is stretched is hinged so that it can swing freely toward the outdoors, and the lower edge of the window plate 3 approaches and separates from the lower edge of the window frame 2 to open and close. A plurality of swinging opening/closing windows 1 are connected horizontally and fitted into the wall of the building.

A cylindrical body 5 having a rectangular cross section elongated in the left and right direction and having a left and right guide groove 6 formed on the right side of the upper surface is attached to the lower edge of each window frame 2 by screws 7,
A slider 8 that fits almost tightly into the inner surface of the cylinder 5 is slidably inserted into the right side of the cylinder 5, and a circular fitting part 9 protruding from the upper surface of the slider 8 is inserted into the guide groove. 6, and one end of the link 11 is connected to the shaft 10, which projects from the center of the fitting part 9 to the outside of the guide groove 6, by a ball joint 12 so as to be able to swing freely. The other end of the link 11 is connected to a shaft 15 protruding from a bracket 14 attached to the longitudinal center of the lower edge of the window plate 3 by a ball joint 16 so as to freely swing. At the same time, on the left side of the slider 8 in the cylindrical body 5, a movable body 18, which also fits approximately tightly into the inner surface of the cylindrical body 5, is slidably fitted, and the slider 8 and the movable body 18 are Between,
Two compression coil springs 20, 20 are attached by fitting their ends into mounting portions 21 and 22 that protrude from the corresponding surfaces of the slider 8 and the movable body 18.

The slider 8 and the movable body 18 have insertion holes 24 and 25 at the center in the width direction, and insertion grooves 26 and 27 at the front side surface along the length of the cylinder 5, respectively. It is formed with
One end of one wire 30 is introduced into the cylindrical body 5 of the swing opening/closing window 1 closest to you, and is inserted into the insertion hole 25 of the movable body 18, between the two compression coil springs 20, 20, and the vibrator 8. through the insertion hole 24 of the window frame 2.
As mentioned above, the slider passes through the insertion hole 25 of the movable body 18 of each swing opening/closing window 1 and the insertion hole 24 of the slider 8 one after another. The cable is routed so that it turns around a pulley 31 attached to the farthest window frame 2 and returns to the front through the insertion groove 26 of each slider 8 and the insertion groove 27 of the movable body 18. , a U-shaped first pressing body 32 is attached to the wire 30 routed through the insertion holes 24 and 25 in the center of each slider 8 and the movable body 18 on the right side of each slider 8. is applied to the right end surface of the slider 8 and fixed by tightening the leg portion with a screw 33, and the multi-moving body 1
On the left side of 8, a second pressing body 34, which also has a U-shape, is applied to the left end surface of the movable body 18 with the compression coil springs 20, 20 slightly elastically compressed, and the leg portion is tightened with a screw 35. In addition, both ends of the wire 30 are attached to a turning pulley 3 attached to the window frame 2 on the nearest side.
6, 36 and 37, 37, and both ends of the geared cable 39, which is made by spirally winding a fine steel wire around the strands, are attached to the fittings 4 at both ends of the wire 30.
It is connected at 0.40 to form an endless shape,
This geared cable 39 is rotated by a gear 43 that has meshing teeth that engage the geared cable 39 on its outer circumferential surface, which is rotationally driven by an operating handle 42 installed in an operating box 41 installed at a low place in the building. ing.

Next, the operation of this embodiment will be explained.

When the operating handle 42 is rotated counterclockwise in FIG. The slider 8 is pulled to the left in FIG. As a result, the link 11 pushes the center part of the lower edge of the window plate 3, opening the window plates 3 all at once, and the fitting part 9 of the slider 8 moves to the left end of the guide groove 6. Part 6a
The fenestration is completed when it hits.

On the other hand, when the operating handle 42 is rotated clockwise, the wire 30 is pulled in the direction of the arrow B and the first
The wire 30 on the side to which the pressing body 32 and the second pressing body 34 are fixed is pulled to the right side in FIG.
The pressing body 34 pushes the movable body 18 and presses the left side surface of the slider 8 while elastically compressing the compression coil springs 20, 20, so that the slider 8 moves to the right side along the guide groove 6. As a result, the link 11 pulls the central part of the lower edge of the window pane 3 and the window panes 3 are closed all at once. As in the case of operation, the second pressing body 34
If the structure is such that the slider 8 is directly pressed, if there is a difference in the timing at which each window panel 3 is completely closed due to installation error, one window panel 3 may be pressed against the other window panel 3. If the window completely closes before it hits the window frame 2, the wire 30 cannot be pulled any further and it becomes impossible to press the slider 8 corresponding to the window plate 3 which is not completely closed. In this embodiment, the second pressing body 34 presses the slider 8 via the compression coil spring 20, so that the window plate 3 may be left unsealed. Because of this, even if one window panel 3 is completely closed before the others, the compression coil spring 20 attached to the slider 8 corresponding to the closed window panel 3 is elastically compressed and the wire is 30 can be further pulled, and the sliders 8 connected to the window panels 3 that are not yet closed can be further pressed, making it possible to completely close all the window panels 3.

Note that the device of the present invention is not limited to the case where the upper edge of the window plate is hinged to the window frame as shown in the embodiment, but can also be applied to an outward-style swinging opening/closing window where the lower edge of the window plate is hinged to the window frame. can also be applied.

Structure and effects of the device As specifically explained in the above embodiments,
The swing opening/closing window opening/closing device of the present invention hinges one of the upper or lower edges of the window plate to the corresponding edge of the window plate, and the other edge of the window plate is attached to the window frame. A plurality of swinging opening/closing windows are arranged in a row in the horizontal direction so as to be opened and closed by approaching and separating from the other edge of the window frame, and a sliding guide is provided in the length direction of the other edge of each window frame. A slider that slides along each sliding guide and a substantially central portion in the length direction of the other edge of each window plate are connected by a link, and a slider that slides along each sliding guide is connected with a link, and A wire that is pulled in both directions is routed through each of the sliders, and a first pressing member that contacts one side of each of the sliders and a second pressing member that contacts the other side of the slider via an elastic member are connected to the wire. 2 pressing bodies are fixedly installed, and by pulling the wire in one direction, each of the first pressing bodies presses each of the sliders to open the window, and by pulling in the other direction, each of the second pressing bodies opens the window. The main feature is that the pressing body presses each of the sliders through each of the elastic bodies to close the window, and a wire is connected to the slider connected to the window plate via a link. The window panel was opened or closed by pulling the wire in one direction or the opposite direction and pressing the slider with a first pressing member or a second pressing member fixed to the wire. This allows the wire to fit into the window frame side when the window is opened, giving it an aesthetically pleasing appearance and preventing the wire from rusting.Also, there is no need for a biasing device, and one end of the link can be connected to the non-hinged side of the window panel. By connecting the edges of the windows to approximately the center in the longitudinal direction, it is possible to apply pressure or tension to approximately the center of the window plate, and by attaching one link to each swing window, the window can be closed. Since the plate can be opened and closed in a well-balanced manner, the structure can be simplified and costs can be reduced.Furthermore, an elastic body is placed between the slider and the second pressing body that presses the slider when closing the window. Because it is interposed, even if there is a difference in the timing when each window panel completely closes due to installation error, and one window panel closes before the other, the elastic body corresponding to that window panel can be elastically compressed. At the same time, the wire can be further pulled and the slider connected to the other window panels can be further pressed, resulting in the effect that all the window panels can be completely closed in the same way.
