Installation, and proximity switch is configured to be coupled to a first when the position of the lever 410 to change warning light 404 flashes along with the audible alarm generates an alarm sound generator (not shown) and a warning light 404.

In addition, although not shown on one side of the frame 501 of the scaffold 500, it is obvious that the scaffold member 502 and the handrail member 503 are provided with locking pins that maintain the folded state, and the scaffold member 502 as shown in FIG. ) And the handrail member 503 automatically removes the locking pin through the cylinder 505 acting in the direction of pushing the piston 504, and the scaffold member 502 and the handrail member 503 are automatically "c." "To be unfolded in the shape of the frame, the frame 501 is provided with a top bar 506 and a diagonal bar 507 rotatably, and the handrail member 503 takes the top bar 506 and diagonal bar 507 Each of the hooks 508 and 509 may be provided so as to prevent the opposite side of the ladder member 502, and the footrest member 502 and the handrail member 503 stand on the balcony railing R. A plurality of safety rods 510 are fixed in the longitudinal direction so as not to step on them.

In addition, as shown in FIG. 6, a plurality of brackets 105, 205, and 305 having a closed shape are selected from the side bars 102, 202, and 302 of each ladder 100, 200, and 300. And brackets 105, 205 and 305 are rotatably coupled to the semicircular safety rings 106, 206 and 306, respectively, and the ladders 100, 200 and 300 are When fully folded, each sidebar 102, 202, 302 of any ladder is configured to be positioned midway between the sidebars 102, 202, 302 of another ladder that is adjacent.

There is also a need for a return device 600 capable of repositioning the ladder 100, 200 and 300 in a fully unfolded state, which is a switch (not shown) operation at the top center of the outermost ladder 100 as shown in FIG. It is provided with a motor 601 to selectively operate in accordance with, the upper end of the outermost ladder 100 is provided with a rotating rod 602 in the transverse direction so that the middle and the shaft of the motor 601 is geared to each other, Drums 603 are formed on both sides of the rotating rod 602, and the drum 603 and the upper end of the innermost ladder 300 are connected by wires 604.

Referring to the operation of the emergency evacuation ladder according to the present invention configured as described above in detail with reference to FIG. 8 as follows.

First, a part of the balcony railing (R) is opened so that the ladder (100, 200, 300) and the footrest 500 is installed side by side in the usual use as a substitute for the balcony railing (R), ladder (100) The (200) and (300) portions are shaped to accommodate all the remaining ladders 200 and 300 inward of the outermost ladder 100, and the scaffold 500 also has a scaffold member 502 and a handrail member 503. Since it is fixed to the frame 501 in a folded state, it becomes neat enough to not recognize that an emergency ladder is installed externally.

In addition, the side bars 102, 202 and 302 of the ladders 100, 200, and 300 are closely structured so that the side bars of any ladder can be positioned in the middle of the side bars of other ladders adjacent to each other for safety. It can be, and the footrest 500 is also securely erected in the longitudinal safety rods 510 on the footrest member 502 and the handrail member 503 can be secured.

At this time, the ladder 100, 200, 300 according to the present invention is to keep the locking rod 303 is fitted to the locking device 400 in a fully folded state, so children lack awareness of the object of the emergency ladder Inadvertently operating the locking device 400 may be said to be exposed to the risk of safety accidents.

In the present invention, in order to improve this, the locking device 400 can be released in two stages, and the first lever 410 is flipped in a direction opposite to the second lever side while the second lever 420 is held. When the pushing protrusion 431 of the pushing member 430 rotatably connected thereto enters into the locking groove 444 of the locking member 440, and then the first lever 410 and the second lever 420. By releasing the pushing projection 431 and the engaging groove 444 is in close contact can be a safe locking state can not move any member except the first lever 410, ladder (100) (200) (300 Locking device 400 is always in this state at all times.

In this state, the first lever 410 is operated to the second lever side to first remove the pushing protrusion 431 of the pushing member 430 from the locking groove 444 of the locking member 440 and place it in front of the pushing surface 443. Since the second lever 420 is rotated in the same direction as the first lever 410 and the locking member 440 is rotated, the locking bar 303 is released by releasing the locking position of the release member 450. If only one of the first lever 410 or the second lever 420 is inadvertently manipulated, the locking position is never released, and thus the safety can be achieved. The first lever 410 is normally positioned at a normal position. In case of change in the proximity switch, the warning light 404 flashes with the occurrence of the alarm sound, so when the child accidentally or inadvertently takes the action of flipping the first lever 410, this can be immediately recognized. To ensure that.

Meanwhile, in case of an emergency such as a fire, the ladders 100, 200 and 300 should be taken out quickly and evacuated to the balcony of the lower floor. In this case, as described above, the first lever 410 and the second lever 420 should be evacuated. ) In sequence, the pushing protrusion 431 of the pushing member 430 connected to the middle pushes the pushing surface 443 of the locking member 440 so that the locking member 440 is rotated, and the locking member 440 is rotated. ) Rotates, the semicircular cam 442 integrally formed on the shaft 441 is rotated together, the locking jaw 452 of the release member 450 is free, and the locking position of the release member 450 is released. When the release member 450 is rotated by the weight of the ladder 100, 200, 300 hanging on the locking groove 451 through the locking bar 303, the locking bar 303 from the locking groove 451 All ladders 100, 200, and 300 fall out at a high speed while falling, and buy each ladder to be caught between adjacent ladders. Stoppers (104, 204, 304) are located at the upper end or the lower end of the (100) (200) (300) that the ladder (100, 200, 300) is not completely out of the state, When the ladders 100, 200, 300 are pulled out, semi-circular safety rings 106, 206 provided on the side bars 102, 202, 302 of each ladder 100, 200, 300. 306 is rotated forward by the downward force of each ladder 100, 200, 300, brackets 105, 205, 305 for supporting the safety ring 106, 206, 306 is Since the lower portion is formed in a clogged shape, the safety rings 106, 206, and 306 are completely unfolded while forming a right angle with the ladders 100, 200 and 300, respectively.

In addition, when the locking pin that secures the scaffold 500 is pulled out, the piston 504 of the cylinder 505 interposed between the scaffold member 502 and the handrail member 503 comes out, and the scaffold member 502 and the handrail are pulled out. By pushing the member 503, the scaffold member 502 and the handrail member 503 can be rotated forward, and the scaffold member 502 is caught by the balcony slab S to stop at a point perpendicular to the frame 501. Since the cylinder 505 is interposed between the scaffold member 502 and the handrail member 503, the handrail member 503 also stops at a point perpendicular to the scaffold member 502. 502, the handrail member 503 is to be spread in the "c" shape, the footrest member 502 is supported by the balcony slab (S) may have a support force that can hold up sufficiently even if the person is raised, scaffolding The ladder side of the member 502 is opened to climb on the ladder 100, 200, 300 through this There is a possibility of falling to the other side, but in order to prevent this, the upper bar 506 and the diagonal bar 507 rotatably provided on the frame 501 by the person who climbs on the first scaffold 500, the handrail member 503 When hooked to the hooks 508 and 509, respectively, the opposite side of the ladder member of the scaffold member 502 can be blocked and safety can be improved, as well as the support force of the scaffold member 502 and the handrail member 503 can be improved. .

When the ladders 100, 200, 300 and the footrest 500 are both unfolded, the footrest member 502 comes out to the footrest member 502 through the four-frame 501 without having to climb the balcony railing R. Step on the ladder to climb the ladder (100) (200) (300) through the exit through the ladder (100) (200) (300) next to the ladder (100) (200) (300) is at least Downstairs balcony is to go down the ladder (100, 200, 300) to escape to the lower floor urgently, the horizontal bars (102, 202) of each ladder (100, 200, 300) ( 302 is provided with a number of semi-circular safety rings 106, 206, 306 to ensure safety while descending the ladder (100, 200, 300), ladder (100, 200) Since the 300 is installed in the direction of the building, the gaze of the person who descends the ladder 100, 200, or 300 is to look at the wall of the building, which can give a sense of security psychologically.

If the fire is initially suppressed and there is no damage to the evacuation ladder, or if children accidentally break the evacuation ladder, the evacuation ladder must be restored and reused. In this case, the motor located at the top center of the outermost ladder 100 601 is driven to rotate the rotating rod 602 installed in the transverse direction at the upper end of the outermost ladder 100, and then the wires connected to the upper end of the innermost ladder 300 drum 603 on both sides of the rotating rod 602 604 is wound to raise the innermost ladder 300, that is, the ladder 300 drawn out to the lowermost, the ladder 300 of the innermost ascending ladder 200 and the stopper 204 adjacent to the outside (304) are caught between all the ladders 200, 300 are sequentially raised, the safety ring 106, 206, 306, which was deployed in this process is automatically folded, the innermost ladder 300 upper end Locking bar 303 is released When the release member 450 is rotated in the ascending direction while being locked by the locking groove 451 of the ash 450, the cam 442 of the locking member 440 is free and the locking member 440 is rotated by its own weight. When the locking member 440 is rotated, the cam 442 is caught by the latching jaw 452 of the release member 450 and the ladders 100, 200, and 300 are automatically locked and fixed in this state. Holding the second lever 420 and flipping the first lever 410 in the direction of the second lever 420, the pushing protrusion 431 of the pushing member 430 is inside the locking groove 444 of the locking member 440. If the position is secured to the ladder 100, 200, 300 in a safe state.

In addition, when folding the scaffold 500, first, the upper bar 506 and the diagonal bar 507 connecting the frame 501 and the handrail member 503 are removed from the hooks 508 and 509, and then the handrail member ( When the force is applied in the pulling direction 503, the piston 504 enters the inner side of the cylinder 505 and the railing member 503 is folded in the direction of the scaffold member 502, and then the scaffold member 502 is framed. If you turn the locking pin to rotate in the direction 501, the footrest 500 will also be easily folded.
