The present invention relates to a telescopic emergency escape device capable of escaping from an upper floor to a lower floor in an emergency.

In the event of a fire in a general building, people must be evacuated quickly and safely from the scene of the fire. In particular, in a fire such as a high-rise building or apartment, the smoke from the fire quickly spreads to the upper floors, so the means of evacuation should be evacuated to the lower floors using stairs. In case of fire, stairs are filled with smoke and it is difficult to evacuate to a place where it is difficult to evacuate.

Currently, under the 10th floor, an evacuation is attempted by using a sledgehammer, but the safety-vulnerable class such as the elderly or children cannot use it. 16. Disclosure) of "Emergency Escape Device" has been disclosed.

On the other hand, when the vehicle 150 rises to the upper floor, the escapee located on the upper floor rotates the second lever 147 to the initial position, which is the safe boarding position.

When the second lever 147 is rotated to the safe riding position, the pressing force of the operation link 149 by the inclination portion 148a of the cam 148 is released, and the first lever 142 supports the first lever 142 by the support spring. The lever 142 releases the pressure of the operation valve 137 by the pressure pin 143 .

When the pressure of the operation valve 137 is released, the operation valve 137 rises again by the internal pressure of the cylinder body 133 to seal the orifice 135, and the upper space 133a of the pushing piston 132 and By blocking the movement of the high-pressure gas to the lower space (133b) stops the movement of the pushing piston (132).

When the boarding body 150 is lifted from the upper floor by the second lever 147, the escapee climbs up the boarding board 155 and boards the boarding body 150, and again the first lever of the first switch 141 ( By rotating 142 downward to open the orifice 135 by the actuating valve 137, and lowering the vehicle 150 by the weight of the escapee, the first switch 141 and the second switch 146 repeatedly By elevating and lowering the vehicle 150 according to the in operation, continuous escape may be attempted.

Therefore, the telescopic descending evacuation device of the present invention elevates and descends the vehicle 150 according to the extension and reduction of the length of the telescopic column 110, so there is no need for a structure to connect the upper and lower floors. Not only is it easy, but even if the length of the telescopic pillar 110 is stored in an extended state, only the telescopic pillar 110 is visible from the outside, and in a state in which the length of the telescopic pillar 110 is reduced, the boarding cover portion of the vehicle 150 ( 151), it is possible to visually prevent the occurrence of disgust and prevent the deterioration of the aesthetics of the surrounding environment.

In addition, since the boarding body 150 is installed on the upper part of the telescopic pillar 110 and the telescopic pillar 110 is covered by the boarding cover part 151 of the boarding body 150 , the escapee boards the boarding body 150 . When descending from one state, the operating components are not exposed to the outside, thereby preventing the occurrence of a safety accident in which the body of the escapee is damaged, and the operating components are not exposed to the outside, thereby providing a sense of stability from the escapees.

In addition, it is possible to adjust the elevating speed of the vehicle 150 by adjusting the amount of air flowing into and out of the telescopic column 110, as well as the high-pressure gas in which the link operation mechanism 130 is charged and the load caused by the escapees. Because it operates by a power supply, it does not require power, so it can be used even in the event of a power outage.
