Telescopic evacuation ladder and telescopic evacuation ladder equipment

摘要

[Problems] evacuees in body weight can increase the force that supports, and broken repeatedly can be used hard, further, to provide a light-weight an inexpensive telescopic evacuation ladder. The apparatus includes a pair of Suridohashira-tai 22 and 22, stretching the slide unit 21 and a scaffolding for conjugate 23 that bind together the pair of Suridohashira-tai 22, 22 is provided with multiple connection with a telescopic body 16 which can, for the second Suridohashira-tai 22 of the first Suridohashira-tai 22, and a second slide unit 21 of the first slide unit 21 for connecting these to one another, the first and second slide a sliding portion 24 for connecting slidably the pillar 22 in the stretching direction is provided, the first convex portion 29 together is provided on the first Suridohashira-tai 22, second Suridohashira-tai 22 the second convex portion 30 is provided, when the first and second Suridohashira-tai 22 becomes stretched state, have a first convex portion 29 and the second convex portions 30 abut one another, the configuration for locking the movement direction of elongation of the first or second Suridohashira-tai 22 and 22. .BACKGROUND 5
