Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for opening and closing a smoke exhaust window installed in the upper part of a wall in order to exhaust smoke filling a room to the outdoors when a fire occurs.

The original purpose of the smoke exhaust window to be solved by the conventional technology and invention is to be used in the event of a fire, so even if it is driven by an electric motor, it will not become inoperable due to the heat of the fire. Conventionally, an operation box with a manual operation means such as a handle was installed exposed at the bottom of the wall where manual operation could be performed, and connected to the smoke exhaust window installed at the top of the wall using a control cable. I was doing it, but
Since the control box is exposed at the bottom of the wall, it not only spoils the aesthetics and gets in the way of indoor use, but also requires a long control cable due to the distance between the control box and the smoke exhaust window. The drawback was that the frictional resistance was large, the operating force transmission efficiency was low, and a large electric motor had to be used.

Means for Solving the Problems The present invention, as a means for solving the above-mentioned problems, provides a drive system for each opening/closing drive device attached to each of a plurality of smoke exhaust windows connected to the upper part of the wall of a building. An electric motor is installed and the electric motor is surrounded by insulation material.

Functions and Effects of the Invention Since the smoke exhaust window opening/closing device of the present invention has the above structure, the electric motor, which is sensitive to heat, is protected from the heat of the fire by the heat insulating material, suppressing the rise in temperature, and at least keeping the temperature constant immediately after a fire occurs. In addition, even if the electric motors for some windows become inoperable, the electric motors for other windows will operate normally and any smoke evacuation window will be activated. can be opened, allowing the smoke that has filled the room to escape.

Further, since each opening/closing drive device is driven by a separately mounted electric motor, there is little reduction in driving force transmission efficiency, and a small electric motor can be used.

Embodiments Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings.

Figures 1 to 3 show the first embodiment, and in Figure 1, 1 is an outward folding window in which a window plate 3 is hinged to the lower edge of a window frame 2 fitted into the upper part of the wall of a building. There it is.

A plurality of window frames are installed in a row in the horizontal direction, and on the upper edge of each window frame 2,
A horizontal part of a mounting member 8 having an angular cross-section, in which a chain case 7 that accommodates a push-pull chain 5 that can be bent only on the - side and supports a sprocket 1-6 meshed with the chain case 7 is attached to the inside of each window frame 2. It is fixed to the lower surface, and the tip of each chain 5 is connected to the upper edge of each window plate 3. Plasterboard lO of a predetermined thickness is pasted on the inside of the vertical and horizontal parts of each mounting member 8, respectively. A gear box 11 is installed on the upper surface of the plasterboard 10 attached to the horizontal part.
is fixed, its output shaft 12 passes through the gypsum board 10 and the mounting member 8 and is connected to the rotating shaft 14 of the sprocket 6 in the chain case 7, and the gear 15 connected to the output shaft 12 connects to the input shaft 16. The worm wheel 1 is connected to the input shaft 16 and meshes with the gear 17 connected to the input shaft 16.
8 is.

It engages with a worm 21 connected to the output shaft of a reversible motor 20 fixed to the gear box 11, and around the gear box 11 and the reversible motor 20, there is a steel plate having an L-shaped cross section and closing plates at both ends. frame 13 made of
A cover 23, which is made by pasting plasterboard 22 of a predetermined thickness on each inside surface, is fixed to the mounting member 8 by tightening screws 24 to the bracket 29, and the gear box 11 and reversible motor 20 are isolated from the outside. It has been done.

A power supply line (not shown) that supplies power to each reversible motor 20 passes through the cover 23 and is routed along the window frame 2, and is connected to a switch box provided at the lower part of the wall surface, and the fenestration switch is turned on. The reversible motor 20 rotates in one direction, and the output shaft 12 of each gear box 11 rotates via the worm 18 and gear 15.17, and the sprocket 6 connected thereto rotates, causing each chain case 7 to rotate. The inner push-pull chain 5 is unwound, and as a result, each window panel 3 swings outward all at once to open the window, and when the window closing switch is turned on, each reversible motor 20 rotates in the opposite direction. By rotating the sprockets 6 of each chain case 7 in the opposite direction, each push-pull chain 5 is drawn into each chain case 7, and each window plate 3 swings inward to close the window. Each reversible motor 20
is surrounded by the gypsum board 10° attached to the mounting member 8 and the gypsum board 22 attached to the cover 23, so in the event of a fire, each reversible motor 20, which is vulnerable to heat, will be protected from the fire. protection from heat, to prevent inoperability due to heat for at least a certain period of time after the onset of a fire;

Since each window plate 3 is opened and closed separately by each reversible motor 20, even if some of the reversible motors 20 become inoperable, the other reversible motors 20 will operate normally and eventually The window panel 3 is opened to allow smoke filling the room to be exhausted.

FIGS. 4 and 5 show a second embodiment, and in FIG. 4, numeral 31 indicates the embodiment in which a window plate 33 is hinged to the lower edge of a window frame 32 fitted to the upper part of the wall of a building. A box 37 that rotatably supports and accommodates a gear 34 is attached to the upper edge of each window frame 32. A guard cable 35 of a predetermined length is inserted into each box 37 in parallel with the window frame 2 and connected to the gear 34. The right side protruding portion of each box 37 of each guard cable 35 is slidably inserted into the accommodation tube 36 connected to the box 37, and the left side protruding portion is inserted into the box 37. The guard cables 35 are slidably inserted into the connected bent conduit 40 whose tip end is bent outward and protrude from the tip thereof, and the tip ends of the protruding guard cables 35 are connected to the upper edge of each window plate 33, respectively. A gear box 11, which is the same as that in the above embodiment and has a reversible motor 20 attached thereto, is fixed to the upper surface of a plasterboard 10 attached to the upper surface of the horizontal part of each mounting member 8, and its output shaft 12 is The box 3 is inserted through the plasterboard 10 and the mounting member 38.
