The outer end of the mounting table is close to the outer wall of the building.

As a result, when the user mounts the lifting device on the lifting device mounting platform and descends on the lifting device, the user descends from a position close to the outer wall of the building, and thus there is a problem of being easily exposed to flames or smoke spreading from the downward direction. .

The most important point in case of fire is that there is no time to prepare for evacuation, so it is necessary to escape before Golden Time before loss of consciousness due to suffocation. However, the conventional evacuation equipment had a problem that escape was not focused before Golden Time. .

In other words, in the case of an urgent situation due to the occurrence of a fire, a separate storage device can be found and installed on the steel bar, and the belt of the steel bar can be worn on the body and the steel bar can be rotated to the outside of the building to escape from the building. In such a rapid escape, there was a fear that the golden time to escape from choking could be missed due to the delay of time, such as preparing after recognizing the accident.

In addition, there has always been the unfortunate area of technical solution that such a stubborn system is not available unless it is a young, powerful, fearful person or a highly trained professional.

In the swing-out-down emergency escape device composed of a fixed frame 401, a rotating frame 200, a wire 300, and a lowering device 400 as described above, the rotating frame 200 and the wire 300 and Ladder 400 may be composed of a plurality of people may be configured to sequentially escape using a single emergency escape device, the structure is shown in FIG.

More specifically, the plurality of rotating frames 200 are made to have the same shape and size, and the plurality of rotating frames 200 having the same shape and size are arranged to have a structure overlapping with each other.

In this case, the two rotation frames 200 which are disposed adjacent to each other may be spaced apart from each other to secure a space for the placement of the stiffener 400 and the rotation operation of the rotation frame 200.

In addition, the plurality of rotating frame 200 is made to be converted to the second posture while rotating independently irrespective of the adjacent rotating frame 200, which is the elastic plate 500 or the hinge unit for each rotating frame 200 Although installed, the elastic plate 500 or the hinge unit which is installed in the plurality of rotating frame 200 can be implemented by being fixed to the fixed frame 401 at different positions.

The plurality of wires 300 are installed to connect the rotating frame 200 and the fixed frame 401 in a one-to-one manner, so as not to interfere with the rotation of the other rotating frame 200, the inner space or the outer side of the rotating frame 200 It is installed to connect the fixed frame 401 and the rotating frame 200 through the space.

Emergency escape device according to the present invention configured as described above is usually installed on the veranda or window frame so that it can be used quickly in case of emergency, the rotation frame 200 by a separate rope or binding device in a vertical first posture state It is fixed to the fixed frame 401 to maintain the first posture.

On the other hand, when the escape from the high-rise building is required due to the occurrence of fire or other disasters, the user acts on the body belt 470 provided on the waning machine 400 installed on the rotating frame 200, the rotating frame After releasing the rope or the binding device fixed to the fixed frame 401 (200), if you move the weight to the outside of the building, due to the user's weight movement, the rotating frame 200 swing-out-down method Rotate to switch to the second posture.

In the process of switching the posture of the rotating frame 200 as described above, since the elastic member 610 or the binding band 620 installed on the wire 300 does not function at all, the rotating frame 200 rotates at a high speed. As a result, the user can quickly escape from the flame or smoke first.

On the other hand, when the rotating frame 200 is close to the second posture, the unfolding of the wire 300 is delayed due to the elastic member 610 or the binding band 620 installed on the wire 300, accordingly the rotating frame ( 200 is converted to the second posture by rotating at a relatively slow speed, so that the impact transmitted to the user is reduced, and the shaking of the user with the stirrer 400 can be reduced.

In this way, the user can move away from the building by the rotating frame 200, which is switched to the second posture, so that the user can avoid flames and smoke. To escape to the ground.

On the other hand, when a plurality of rotating frame 200 is installed in the fixed frame 401, when the escape of one person is completed by using the outermost rotating frame 200, the remaining rotating frame is disposed behind ( 200 is to try to escape one by one sequentially, when the prepared plurality of rotating frames 200 are all converted to the second posture, several rotating frames 200 are gathered to form a cantilever-shaped support structure Therefore, if necessary, the space provided by the support structure formed by the various rotating frames 200 may be utilized as a temporary evacuation space.

Meanwhile, the first and second wires W1 and W2 are rotated while the first pulley 410 and the second pulley 420 provided in the dropper 400 rotate during the descent using the user's dropper 400. As the unwinder 400 descends with the user descending, in this process, the braking plate 460 contacts the first and second brake wheels 140 and 150 and generates a braking force, so that the user can gradually descend. Will be.

That is, as the weight of the user descending is transmitted to the braking plate 460 as it is, the braking plate 460 is pulled downward, and the braking unit 462 of the braking plate 460 is the first braking wheel 440. It is inserted into the second groove 451 of the first groove 441 and the second brake wheel 450 of the to generate a braking force.

Since the braking force generated in this way increases in proportion to the weight of the user, the user can gradually lower the user regardless of the weight of the user.

Furthermore, the braking plate 460 generates a braking force while contacting all of the first and second braking wheels 440 and 450, and the braking structure composed of the braking plate 460 and the first and second braking wheels 440 and 450 includes: As it is configured on both sides of the two pulleys (410, 420) it is possible to increase the stability.

On the other hand, in the emergency escape process, the user can adjust the descent speed through the operation of the lever 493.

That is, when the user rotates the shaft member 491 through the operation of the lever 493, the second elastic member 406 is pressed by the rotation of the cam member 492 provided in the shaft member 491, and Since the force transmitted to the brake plate 460 through the second elastic member 406 acts in the direction in which the brake plate 460 is pushed up, between the brake plates 460 and the first and second brake wheels 440 and 450. The braking force formed is reduced and the user can descend faster.

18 shows an exemplary view showing the magnitude of the braking force generated while the contact surface of the braking plate is rubbed against the inclined surface of the braking wheel.

In Figure 18, W is the force applied to the braking plate due to the user's weight, θ ₁ is the angle of inclination of the contact surface, and when the frictional load acting on the contact surface is F ₁ , 2F ₁ sinθ ₁ = W, F ₁ the lower the θ ₁ is small close to zero, the greater the force to be determined to infinity when converted to = W / 2sinθ _1.

19 shows an exemplary view showing the magnitude of the braking force generated when the braking plate is rubbed on the two braking wheels.

In Figure 19, W is the force applied to the braking plate due to the user's weight, θ2 is the angle of inclination of the side of the brake, and when the frictional load acting on the brake wheel due to the contact of the brake plate and the brake wheel is F ₂ , 2F ₂ sinθ ₂ = ｗ, and when we convert to F ₂ = W / 2sinθ ₂ , the smaller the θ ₂ and the closer to 0, the greater the force to infinity.

Thus, the friction loads F ₁ and F ₂ have a double V groove brake braking force by θ ₁ and θ₂, and the angles θ ₁ and θ ₂ of the V grooves are comparable to the gear speed increase ratio for doubling the braking force in the gear method. The smaller the angle, the greater the ability.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
