Description

[Detailed Description of the Invention] This invention provides that the window can be closed manually at any speed and speed.
This invention relates to a smoke evacuation device in which a member for opening and closing a window is installed in a concealed manner around a sash, and is configured to be able to open and close windows quickly by returning the projectile to a straight line, and can be extended to multiple windows.

Window opening/closing devices are desired as a means of emitting toxic gas (smoke) and saving human lives in the event of a fire, as they can be opened quickly, are easy to operate, and comply with fire regulations. Prior art has been provided.

However, a common flaw found in all window opening/closing devices is that they are originally made with holes drilled into walls and roofs for lighting, ventilation, views, etc., but the installation of unsightly devices near the windows is a common problem. This not only impairs the aesthetic appearance, but also worsens the view.

For example, in the prior art disclosed in Utility Model Publication No. 52-13155 and Japanese Patent Publication No. 53-35384,
In both cases, the main components for opening and closing windows are a double pulley device (that is, a movable pulley on the window side and a fixed pulley on the crosspiece side), and a wire rope connected to the device disrupts the interior appearance of the area around the window. It also obstructs the view outside and becomes an eyesore.

Other things disclosed in Japanese Patent Publication No. 50-2537 include a ventilation system in which the continuous windows are crossed by a crank rod, which significantly obstructs the view, and there is too much to list.

In recent years, with the spread of disaster prevention equipment, smoke evacuation devices are being installed everywhere, such as in buildings where people frequently come and go.However, on the other hand, smoke evacuation devices that are highly functional and operate without compromising the beauty of the interior are becoming more and more popular in the world. It is an undeniable fact that there are high hopes for this.

The present invention was developed in view of the above-mentioned circumstances, with the aim of meeting the requirements of the fire service regulations and solving the deficiencies of conventional smoke exhaust devices.

An embodiment of the present invention will be described below with reference to the drawings.

The sash 1 is hinged to the upper crosspiece 2 of the opening A at its upper end, and is configured to be rotated outward by the arm rod of an ejector P (described later) to open the sash 1. A plurality of movable pulleys 3, 3 are attached at appropriate intervals l, and a stopper 6 and a fixed pulley 7 are attached to the lower crosspiece 4 side of the opening A at an interval L wider than the attachment interval of the movable pulleys 3. Then, the guiding rope 5, which has one end connected to the stopper 6, is extended from a movable pulley to a fixed pulley in sequence using a multiple pulley mechanism, and a manually operated cable winding machine is fixed to the side of the mullion 9. C via a guide wheel 8. Reference numeral 10 in FIG. 1 is an arm rod of the ejecting device.

As shown in FIGS. 2 and 3, the member including the protrusion device P and the fenestration spring is such that the other end of the arm rod 10, one end of which is pivotally connected to the vertical edge grooves 1B at both ends of the sash 1, has an opening. Guide 1 fixed in mullion 9 of section A
Slider 1 slidably inserted into groove 12 of 1
The arm rod is pivotally mounted on a pin 14 protruding from 3, and the arm rod is tiltably raised and lowered.

Further, the cable 15 connected to the sliders 13, 13 on both sides is directed toward the opening A via the left and right idler wheels 16, 16, a bullet 17 such as a coil spring, and a well-known and commonly used tumble buckle (tension adjuster 18). Standing 9
It is inserted through each inside of the upper crosspiece 2, and is constructed in a square shape.

In this smoke evacuation system, which is equipped with a window opening/closing member as described above, the guiding rope 5 is wound around an internal drum (not shown) by operating the handle of the rope winding machine C, and the lowering starts. Then, the double pulley device consisting of the fixed pulley 7 and the movable pulleys 3 and 3 works to close the window, but at this time, the arm rod 10 of the protruding device P lowers the slider 13 following the closing of the window, so that the slider 13 is lowered. The ammunition 17 is also stretched by the pulling of the rope 10 connected to the rope 13, and is pulled to the maximum when the window is fully closed, that is, when the slider 13 is at its lowest position.
7 also has the highest resilience.

The fenestration device, which makes full use of the ammunition 17, which is the main focus of the structure of this invention, is completely hidden inside the upper crosspiece 2 and the mullion 9 of the opening A, and is concealed when opened. When viewed from the window, the armrest 10 is only slightly visible.

Furthermore, as mentioned above, the double pulley device that serves as a means for closing the window is installed inside the lower crosspiece 4 of the opening A and the lower edge groove 1A of the sash 1.
When the windows are open, the cables 5 are slightly visible, but in this case, the cables 5 are not unsightly in appearance.

Next, the operation of the above smoke evacuation device will be explained.

When opening a window in the event of a fire outbreak or ventilation, first press the push button on the well-known cable winder C (internal structure not shown), and when the window is fully closed, the maximum storage capacity in the upper crosspiece 2 will be removed. Since the biasing force for fenestration by the bomb 17 is indirectly released and pulls the cable 15 in the upward direction, the slider 13 of the protrusion device P connected to the cable 15 also rises, and the slider The window is quickly opened while tilting the arm rod 10 attached to the arm 13 (FIG. 3).

In such a case, it goes without saying that any cable winding machine uses means (such as a circular governor device or other braking device) to dampen the acceleration caused by the opening bias.

When closing the fully opened window, the operating handle of the cable winder C is usually rotated in the clockwise direction (to the right). The sash 1 is wound around the opening A as shown in the well-known double pulley motion with the connecting part of the stopper 6 as the fixing point.
The lead cable 5 moves toward the lower crosspiece 4 in proportion to the shortening of the lead cable 5, and is finally fully closed. Therefore, as soon as the window closing movement begins, the arm rod 10 of the protruding device P lowers the slider 13 while tilting, and the ammunition 17 in the upper crosspiece 2 is lowered by the lowering of the cable 15 connected to the slider 13. As a result, when the window is fully closed, the bullet 17 is stretched to the maximum extent, and at the same time the energy for restoring is stored to the maximum. A guide line 5 for opening the window by means of a stop mechanism (not shown)
The closed window is maintained until the lock is released.

In this invention, a conventional multi-pulley device is installed inside the lower edge groove 1A of the sash 1 and the lower crosspiece 4 of the other opening A so that it cannot be seen from the outside, and when the window is closed, a protrusion device P accompanying the closing of the window is provided. Energy for fenestration is accumulated by lowering a slider linked to the arm rod of the cable winder C, and a check mechanism that indirectly locks the fenestration energy in the rope winder C is released by pressing a button. Window energy acts instantaneously and the conductor extends, and the sash is pushed forward by the armrest to open the window, but all these parts for opening and closing the window are connected to the sash, upper and lower crosspieces, and It is housed in a concealed manner within a mullion, and only the arm of the protruding device can be seen from the outside, so the area around the window has a striking structure that does not look unsightly or obtrusive, and it does not require expensive oil. Alternatively, it is possible to install a bomb that can be replaced in a concealed manner without having to expose and attach a fenestration bomb such as a gas damper, and in case of an emergency, it can be accessed from the cable winder C. It is constructed so that it can be opened reliably with one touch (push button operation) and complies with the regulations, and when installed on multiple windows, the above-mentioned fenestration device is attached to each window (sash) side and the window can be closed. By connecting the guiding cable, which is a part of the window means, to the multiple pulley device of another adjacent window, various effects such as successive opening and closing of windows can be achieved even more closely than multiple windows.
