[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fire protection device for a window which is used by being attached to the outside of a window of a house, a building or the like.

[0002]

[Prior art]

 When a fire occurs, the window glass of a house or building near the fire site is cracked by high heat, and the fire enters through the broken window, often burning the house or building. In order to prevent this, various types of window fire protection devices have been commercially available, but all of them are extremely complicated in structure and expensive, and the mounting means are extremely troublesome, which makes them difficult to use. It was inconvenient.

[0003]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned conventional drawbacks, has a very simple structure, can be provided at low cost, and can be easily attached to the outer wall, which is a very convenient window for use. The purpose of the invention is to obtain a fire protection device.

[0004]

[Means for Solving the Problems]

 As a means to achieve this, the present invention attaches a heat sensor to the front part of the outer frame whose front and rear surfaces are open, and a steel cord connected to this heat sensor is rotatably attached to the outer frame. Fixed to each fire prevention panel provided with an engaging groove at the end thereof, each fire prevention panel is lifted in an inclined state, and a lock for preventing rotation of the fire prevention panel is provided on the top plate of the outer frame and the inner wall of the bottom plate. A stop piece is provided, and further, mounting portions provided on the top plate and the bottom plate of the outer frame are screwed to the outer wall portion of the window.

[0005]

【Example】

 The construction of the window fire protection device of the present invention will be described in detail with reference to the embodiments shown in the drawings. Reference numeral 1 denotes an outer frame whose front and rear faces are open, and a heat sensor 3 is attached to the front part of the top plate 2 of the outer frame 1. Reference numeral 4 denotes a fireproof panel, which is formed by pressure-bonding a fireproof material (flexible board) 6 to a steel plate 5. In addition, the fireproof panel 4 is provided with a rib 7 in the central portion of the steel plate 5 so that the central portion does not warp or distort. Further, engaging grooves 8 are formed at the ends of each fire protection panel 4. When the steel cords are cut by the high heat caused by a fire and each fire prevention panel 4 rotates by its own weight, each engagement groove 8 of each fire prevention panel 4 meshes with each other to integrate each fire prevention panel 4 with each other. Have a role to play. Further, in order to allow each fire-preventing panel 4 to rotate clockwise by its own weight, an appropriate portion of the lower half portion of each fire-preventing panel 4 is rotatably attached to the side wall 9 of the outer frame 1. Further, the steel cord 11 connected to the heat detector 3 is fixedly attached 12 to each fire prevention panel 4, and each fire prevention panel 4 is suspended in an inclined state. Reference numeral 13 is a pulley for guiding the steel cord 11. Locking pieces 15 and 16 for preventing the rotation of the fireproof panel 4 are provided on the inner wall portions of the top plate 2 and the bottom plate 14 of the outer frame 1. Further, the mounting portions 17, 17 provided on the top plate 2 and the bottom plate 14 of the outer frame 1 are fixed to the outer wall portion 19 of the window with screws 18, 18. Reference numeral 20 denotes a sash portion attached to the window 21.

Since the present invention is configured as described above, when a fire occurs, the high heat thereof is detected by the heat detector 3, and the steel cord 11 is cut. When the steel cord 11 is cut, the fireproof panels 4 lifted up in an inclined state rotate by their own weight in the clockwise direction as shown by the arrows, and the engagement grooves 8 of the fireproof panels 4 are engaged with each other to prevent the fireproof panels 4 from engaging. The fire panel 4 is integrally connected and closes the outside of the window 21 (see FIG. 3). Therefore, the high heat generated by the fire is blocked by the fireproof panel 4 that is integrally connected, so that the window glass of a house or building will not be broken. Therefore, unlike in the past, the window glass will not be cracked by the high heat caused by the fire, and the fire will not enter from the broken window, and the houses and buildings will not be burned.

[0007]

[Effect of device]

 As described above in the embodiments, according to the present invention, when a fire occurs, the steel cord 11 is cut due to the high heat, and at the same time, each fire protection panel 4 is rotated by its own weight to close the outside of the window 21. Therefore, cracking of the window glass (sash portion) 20 due to high heat can be prevented. Further, the fire protection device for a window of the present invention can be provided at a low cost because of its extremely simple structure, and can be easily attached to the outer wall of the window by screwing, which is extremely convenient in use. It has excellent effects such as being certain.
