The present invention relates to a screen fire shutter installed in an elevator, and in particular, in the form of a cloth, it is light and easy to install the shutter and inexpensive, so that the frame guided by the screen cloth can be folded to allow the installation of an emergency door, It was made to have an effective blocking effect on the fire and smoke coming in through the hoistway.

In general, a fire shutter is installed in each part of a building to prevent the spread of fire and to facilitate evacuation in case of fire in the building.

In recent years, when a fire breaks out, the elevator's hoistway acts as a chimney, and flames and smoke flow into each floor without any restriction, causing fire spreading and fatal damage to the building. The fire shutter was installed.

As described above, the fire prevention shutter installed at the entrance of the elevator is formed of steel, but these shutters are heavy and bulky and occupy a lot of space according to the installation. It is difficult to form an emergency door for evacuation of the shutter itself, so there is a disadvantage in that a separate door must be manufactured. Therefore, the installation is complicated and expensive.

Therefore, in order to make up for the above problems, a fireproof shutter formed of a screen cloth having heat resistance, light weight, and small volume has been proposed, and a lower frame is attached to the bottom of the screen cloth to keep the fabric taut. The guide rail protrudes at the entrance of the guide rail and is guided to the guide rail to allow the screen fabric to move up and down. Leaking is a drawback.

In addition, since it is in the form of a cloth, there is a disadvantage that it is easily missed from the guide rail to guide the lifting of the shutter.

In addition, the guide rail is installed to protrude at the entrance of the elevator has the disadvantage that the inlet to evacuate by the thickness of the guide rail installed.

Therefore, the present invention is to solve the above-mentioned conventional problems and is formed on the ceiling of the elevator entrance to form a protruding piece in the lower frame formed to unfold the cloth in the lower end of the screen cloth when lowered in the event of a fire occurs to the upper side Fix a plurality of rivets at regular intervals so that they can be guided well without being separated from the guide rails, and the guide rails can be mounted inside the wall so that the entire guide rails can be folded and opened to form an emergency exit. It is to have an effective blocking effect.

In order to fix the guide rail to be opened and closed as described above, a magnet and a locking means operated by elasticity are attached to a fixed frame embedded in a wall to lock the guide rail when it is closed after being opened.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the structure of the screen shutter of the present invention is wound on the ceiling of the front of the inlet of the elevator lower end to stretch the fabric tightly to the lower end of the screen cloth (10) operated up and down by the motor (M) When the frame 20 is mounted, the screw is fixed to the upper end, and when one side of the lower frame 20 is lowered, a protruding piece 21 is formed so as to be guided without being separated from the guide rail 30 and an upper side thereof. A plurality of rivets 11 are attached at regular intervals in the direction, and the guide rails 30 are formed in the inner space 31 and are bent in a predetermined length inwardly so that the flame retardant film 32 is fitted tightly. 33 is formed on both sides to form a seating portion 41 to the inside of the seating frame 40 is partially embedded in the side wall surface of the inlet of the elevator to be seated on the seating portion (41).

The seating frame 40 is partially embedded in the wall surface is bent so that the guide rail 30 is seated to form a seating surface 41 and to form an inner space 42 to the inner space 42, that is, the seating surface ( It is to form the locking means 44 on the back of the 41.

The guide rail 30 formed as described above is cut up and down by the height of the elevator door to fix the upper end to the seating frame 40 and to install the folding means such as the hinge 34 so that the lower end is folded. The whole is opened and closed, and the locking means 44 is attached to the seating frame 40 so that the guide rail 20 is opened and locked without being lifted from the seating frame 40 by the locking means 44 upon return. It is a configuration to be built.

At this time, the lower frame 20 is a thin steel plate is bent at a narrow top and wide bottom to form an inner space 22 and insert the weight 23 into the inner space 22 and the weight 23 It is wrapped with the screen cloth (10) and fixed to screws or various fixing means to keep the screen cloth (10) more taut when lowered.

At this time, as shown in Figure 5 the ball locking device (44b) by which the ball is operated by the elastic means with the locking means 44 is fixed with a screw 43 on one side of the seating frame 40 and the ball locking device (44b) The groove is formed at the same position of the guide rail 30 to which is attached), so that when the ball is opened and closed, the ball is elastic and locked into the groove.

In addition, a plurality of magnets on the rear surface of the inner space 42 of the seating frame 40, that is, the seating surface 41, so that the guide rail 30 is not lifted by the speed coming down when the guide rail 30 is opened after being opened. When the 44a is attached by various attachment means such as an adhesive, magnetic force is transmitted from the rear surface of the seating surface 41 to the outside to fix the guide rail 30 on the seating surface 41 of the seating frame 40 so that it is not lifted. will be.

The ball locking device 44b in which the magnet 44a and the beads mentioned above are operated by elasticity is attached to the reverse of the above-mentioned and can be locked by the same attachment method and operation.

At this time, when a person pushes the screen cloth 10 when evacuating by sewing the screen cloth 10a of a certain size overlapping the middle portion of the screen installed on the guide rail 30, that is, the position of the human chest. It is to prevent the distortion of the screen cloth 10 to be.

In addition, if the doorway display on the rear surface of the overlapped screen cloth (10a), the emergency door can be easily found by the naked eye during the evacuation of the fire can be made smoothly.

In addition, since the screen cloth 10 used as described above has a small weight and a small volume of the curled state, the screen cloth 10 can be miniaturized and installed in a narrow place. It is to provide a low price.

Therefore, the screen shutter is installed on the ceiling and wound by the motor M, and when a fire occurs, the projected piece 21 and the rivet 11 formed with the wound screen shutter on the lower frame 20 are lowered. The guide rail 30 is guided by the guide rail 30 so as not to be separated, and when fully lowered, when the emergency door marked by the entrance door on the screen shutter is pushed, the entire emergency door is folded and opened so that evacuation is possible. It is fixed to the lock.

Therefore, the entire frame on which the screen cloth 10 is mounted is to have an effective blocking effect against fire and smoke generated by opening and closing.

As described above, according to the present invention, the lower frame 20 and the guide rail 30 to which the screen cloth 10 is attached are provided to enable the formation of an emergency door that can be opened and closed due to the push-in, while the fireproof and It is to have an effective blocking effect against smoke.
