Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a window opening/closing device used for smoke exhaust windows and the like.

(Prior Art) Mid-to-high-rise buildings are equipped with smoke exhaust windows that allow smoke to be immediately exhausted in the event of a fire or the like. In conventional smoke exhaust windows, the lower end of the window body is rotatably connected to the window frame, and the opening in the window frame is opened and closed by tilting the window body inward or outward.

(Problems to be Solved by the Invention) However, in the above configuration, since the window body is inclined when opened, a sufficient opening area cannot be obtained. Additionally, when the wind was strong, the window body was agitated, making it unstable to open and close.

Furthermore, with the outward-tiling method, there is a risk of the building going outside the boundaries of the building, and with the inward-tilting method, curtains, blinds, etc. may get in the way.

Structure of the invention (Means for solving the problems) The invention was made to solve the above problems, and its gist is to move the window body away from the window frame and then move it downward. A window opening/closing device that opens an opening in the window frame, moves the window body upward, and then moves it closer to the window frame to close the opening in the window frame, and (a) moves the window body away from the window frame. (b) A long guide member that is supported by the vertical stile of the window body so as to be slidable in the vertical direction; and (c) An elastic function that moves toward and away from the window frame. has
a support mechanism that supports the guide material relative to the window frame, (d) a pulley provided on the window frame, and (e) a support mechanism provided on the guide material that supports the pulley provided on the window frame; (f) a pulley disposed away from the frame in a direction away from the frame; (f) a pulley provided on the window body and disposed below the pulley provided on the guide material; and (g)
It is spanned almost vertically between the pulley of the window body and the pulley of the guide material to support the window body, and is spanned between the pulley of the guide material and the pulley of the window frame, and one end is fixed. and (h) connected to the other end of this strip, and by winding up the strip, the window body is moved upward and the window body is pushed against the pressing force of the pressing mechanism. A window opening/closing device characterized by comprising: a winding machine that moves close to the frame.

(Operation) By pulling the strip, the window body is raised and then pulled toward the window frame to close it. Also, by loosening the strips, the window body is separated from the window frame and then lowered to open. The window main body is raised by the tension of a strip extending substantially vertically between the pulley of the window main body and the pulley of the guide member. Further, the movement of the window body in the outward and outward directions of the window frame is performed by the tension of the strip between the pulley of the guide member and the pulley of the window frame.

In addition, in FIG. 2 and FIG. 3, in order to simplify the drawings, the air spring 50 is shown only on the left side of the drawings.

The window body 20 is opened and closed by the drive of a rope 60 (stripe body). The details will be explained below.

As shown in FIGS. 1, 4, and 5, pulleys 61a and 61 are provided at both ends of the lower stile 22 of each window body 20.
b is rotatably supported. Three pulleys 62 are provided at the top, middle, and bottom of each second guide member 32.

3c is rotatably supported. The rotation axes of the pulleys 61a and 61b of the window body 20 are horizontal and perpendicular to the window surface (the surface of the glass plate 24 of the window body 20).
Pulleys 62a, 62b, 62c of the guide member 32 and pulleys 63a, 6 at the upper and intermediate portions of the window frame 10
The rotation axis of 3b is horizontal and parallel to the window surface. Further, the rotation axis of the pulley 63c at the bottom of the window frame 10 is vertical.

As shown in FIG. 9, one end of the rope 60 is fixed to the lower part of one of the vertical frames 13 with a fixing metal fitting 65, and from there it is stretched over a pulley 63c provided at the lower part of the vertical frame 13, and It extends horizontally perpendicularly to the lower pulley 62c of the second guide member 32, and extends upward from there to the second guide member 32.
It spans the pulley 62b at the middle part of the vertical frame 32, extends horizontally from there perpendicular to the window surface, and spans the pulley 63b at the middle part of the vertical frame 32, and extends upward from there to the pulley 63a at the top of the vertical frame. It is passed over. moreover,
The rope 60 extends horizontally from the pulley 63a, perpendicular to the window surface, is passed over the pulley 62a on the upper part of the second guide member 32, and from there extends downward along one vertical stile 23 of the window main body 20. extending to the window body 20
The pulley 61a extends from there along the lower stile 22 of the window main body 20 and connects to the other pulley 61a.
b, extends upward from there along the other vertical stile 23, and is spanned over the pulley 62a on the upper part of the other second guide member 32. Further, the rope 60 is passed from the pulley 62a to the pulley 63a at the upper part of the middle frame 14, and then to the pulley 63b at the middle part of the middle frame 14, and the pulley 62 at the middle part of the second guide member 32.
b. Passing through the pulley 62c at the bottom of the second guide member 32, it reaches one pulley 63c at the bottom of the middle frame 14;
From this pulley 63c to the other pulley 63 of the same middle frame 14
spans c.

The above rope 60 is stretched continuously for each window body 20, and finally, the other end is guided to a winder 69 from a pulley 63c arranged at the lower part of the other vertical frame 13. The winding machine 69 has a handle 69a, and by operating the handle 69a and rotating a bobbin (not shown), the rope 60 is wound around the bobbin. Further, a lock mechanism or the like built into the winder 69 prevents the bobbin from rotating and maintains the winding state of the rope 60.

As shown in FIGS. 4 and 5, a roller 70 is rotatably supported at the lower end of the vertical stile 23 of the window body 20. As shown in FIGS. This roller 70 is placed on the upper surface of the lower frame 12 to support the weight of the window body 20.

Next, the operation of the device having the above configuration will be explained.
When the window body 20 is closed as shown in FIGS. 2 and 4, the outer surface of the window body 20 is almost flush with the wall surface X of the building below, and the guide members 31 and 32 are It does not protrude from the wall surface X, so it looks good. In this state, as shown in FIG. 7, the support mechanism 40 is in a shortened state, in other words, the slider 4
2 is in a state of being retracted into the guide member 41.

When an opening is required, the window main body 20 is lowered to open the opening 15 of the window frame 10 as follows,
Exhaust smoke, etc.

That is, the bobbin of the winder 69 is unlocked and the rope 60 is loosened. Then, as shown in FIG. 5, the second guide member 32 is horizontally moved outward and separated from the window frame 10 by the urging force of the air spring 50. At this time, the roller 70
4, the window main body 20 moves horizontally together with the second guide member 32 and leaves the window frame 10 without moving downward.

As described above, the second guide member 32 is attached to the window frame 1.
When the support mechanism 4 moves away from 0, as shown in FIG.
0 is extended, in other words, the slider 42 is the guide member 4
Stand out from 1. In this state, the swing link 48
The claw portion 48a is released from contact with the inner surface of the upper wall of the guide member 41, rotates slightly counterclockwise by the elastic force of the wire spring 49, and projects upward from the hole 42c. As a result, the claw portion 48a is locked to the tip of the upper wall of the guide member 41, so that the slider 4
2 becomes impossible to retreat, and the extended state of the support mechanism 40 is maintained. Further, since the roller 46 hits the stopper 41a in this state, the slider 42 is prevented from falling off. Therefore, each second guide material 3
2, the window frame 10 is supported by a pair of upper and lower support mechanisms 40.
It is stably supported in a vertical position at a position a predetermined distance outward from.

In the state shown in FIG.
When the rope 60 is further loosened,
The window body 20 descends under its own weight. window body 2
0 is lowered at a constant speed by a regulation mechanism built into the winder 69. Since the window main body 20 is guided by the second guide member 32 and the first guide member 31 in the above-mentioned vertical state, it descends along the wall surface X while maintaining the vertical position. At this time, since the second guide material 32 is supported by the support mechanism 40 as described above, it does not follow the window main body 20, and only the first guide material 31 follows due to its own weight.

When the window main body 20 and the first guide member 31 further descend, the first guide member 3
The abutment member 31a provided at the upper end of the second guide member 32b is the abutment member 32b provided at the midway point of the second guide member
As a result, the first guide member 31 is prevented from descending, and from then on, only the window body 20 is guided by the first guide member 31 and descends. Eventually, the abutting member 23a provided at the upper end of the vertical stile 23 is attached to the first guide member 31.
The lowering of the window main body 20 is stopped because it hits the abutment member 31b at the middle part of the window body 20. As a result, the opening 15 of the window frame 10 is opened, allowing smoke and the like to be discharged. Moreover, since the window main body 10 is completely opened, the substantial open area is large and smoke can be efficiently exhausted.

Further, from FIG. 4 to FIG. 6, the first guide member 31 is inserted into the slide groove 23d of the window main body 20 over a sufficient length, and the second guide material 32
is inserted over a sufficient length, the window body 20 and the guide members 31, 32 are maintained in a straight line, and as a result, the window body 20 stably descends and stably opens. maintained. Moreover, since the window main body 20 is arranged along the wall surface,
It is not blown by the wind.

Next, when raising the window body 20 to close it, the handle 69a of the winder 69 is turned to wind up the rope 60. This causes the rope 60 to be pulled. At this time, since the support mechanism 40 maintains the extended state as described above, the positional relationship between the second guide material 32 and the window frame 10 does not change, and the distance between the second guide material 32 and the window main body 20 remains unchanged. Only the positional relationship changes. That is, the pulleys 61a, 6 of the window body 20
1b and the pulley 62a on the upper part of the second guide member 32 are brought closer to each other by the pulling force of the rope 60. As a result, the window body 20 first rises,
Abutment member 23b at the lower end of the window main body 20 at a certain position
hits the lower end of the first guide member 31, and pulls up the first guide member 31 together. Further, the abutment member 31a at the upper end of the first guide member 31 hits the abutment member 32a at the upper end of the second guide member 32,
As a result, the window main body 20 and the first guide member 31 stop rising.

When the window body 20 is raised, the rope 60 is placed along the lower stile 22 of the window body 20, so the rope 60 can hold and support the window body 20, thereby stably raising the window body 20. can be done. Note that the same applies to the above-described descent.

Further, the rope 60 is connected to the pulley 6 of the second guide member 32.
2a and the pulleys 61a, 61b of the window body 20, this rope 60
All of the pulling force acts as a pulling force for the window body 20, and the window body 20 can be raised reliably and smoothly.

Immediately before the window main body 20 reaches the rising stop position, the abutment member 31c provided on the first guide member 31
The claw portion 48b of the swing link 48 of the support mechanism 40 is pushed up against the elastic force of the wire spring 49, whereby the claw portion 48a retreats and is released from the distal end portion of the guide member 41. The support mechanism 40 can be compressed. As a result, the pulling force of the rope 60 causes the pulleys 62a, 62 of the second guide member 32 to
b, 62c and pulleys 63a, 63b on the window frame 10 side,
63c approach each other, and the window body 20 becomes the window frame 10.
move almost horizontally in the direction. Eventually, the window body 20
hits an airtight material (not shown) provided on the window frame 10, and closes the opening 15 as shown in FIGS. 2 and 4. At this time, the slider 42 of the support mechanism 40
follows the movement of the window body 20 and retreats into the guide member 41.

At this time, the rope 60 is connected to the pulleys 62a, 62b, 63c of the guide member 32 and the pulley 63 of the window frame 10.
a, 63b, and 63c, the tensile force of the rope 60 acts as a force to pull the window body 20 toward the window frame 10,
The window body 20 can be reliably and smoothly drawn.

The present invention is not limited to the above embodiments and can be modified in various ways. For example, the support mechanism 40 in the above embodiment may be arranged not horizontally but slightly diagonally downward, and the lower frame 1 which forms the rolling surface of the roller 70 may be arranged.
The upper surface of 2 may be formed obliquely. In this way, when the rope 60 is loosened, the window body 20 can be moved by the push-out force of the pressing mechanism 50 such as an air spring and the weight of the window body 20, and the burden on the pressing mechanism 50 can be reduced. In this case, the window main body 20 can be opened even without the pressing mechanism 50.

The number of support mechanisms and pressing mechanisms can be selected as appropriate depending on the weight of the window body and the like.

Moreover, each support mechanism may be configured with two arms. That is, one end of one arm is rotatably supported by the second guide member, the other arm is rotatably supported by the vertical frame, and both arms are rotatably connected to each other by a support shaft. In this configuration, when the window body is in contact with the window frame, the two arms are bent and contracted, and when the window body is separated from the window frame, they expand in a substantially straight line.

When the window opening and the window body are small, the first guide member of the above embodiment may be omitted and only the second guide member may be slidably inserted into the vertical stile of the window body.

Further, the present invention is not limited to the continuous window type window as in the above embodiment, but may be applied to a single window type window.

Effects of the device As explained above, in the case of the present invention, since the window main body is raised and lowered to open and close, the opening area can be increased and stable opening and closing operations can be performed without being fanned by the wind. . Since the window body is guided by the guide material, the window body can be stably raised and lowered. In addition, because the strips are stretched almost vertically between the pulleys provided on the window body and the pulleys provided on the guide material, almost all of the pulling force of the strips acts as a force to pull up the window body. This allows the window body to be raised reliably and smoothly with a small amount of force.
