OPERATION
The Multiple Exits Escape Chute
is developed from our model: S1 for application on variable
altitdue evacuation, such as above ground railway trains,
gondolas, amusement parks rides etc. The chute has multiple
zippered exits at an interval of 3 meters (approximate 7').
Once reached the safe ground, the escapee just open the closest
zipper to exit the chute. The weight of the chute body is
about 1.4kg/M (1 lb/ft) and can hold up to 1800 kg (approximate
4000 lbs) at once during evacuation. The Chute is made on
spiral form in the left turn direction. The speed of descending
is about 2 meters (7') or less persecond. Therefore, no heavy
shock or impact should be felt when escapee reaches the bottom
of the chute where a pretective landing cushion is attached
for additional protection.
DESCENT & SAFETY
As soon as the escape chute is
completely installed for use check the state of the hanging
chute from another window nearby and start descent in the
chute.
The chute is made in spiral form
in the left turn direction, so try to descend in it turning
the body in the left direction.
The speed of descent is about
2 meters or less per second and the speed never exceeds the
above limit.
Therefore, no shock is felt during the descent in the chute
or at the time when reaching the protecting cushion in the
capsule at the bottom of the chute,
This means that the chute assures
the highest degree of safety and no danger at all.
The protecting cushion of the
capsule touches the ground, which means the escaping person
lands directly on the ground.
Even when many people descend
in the chute in succession, there will be no clogging within
the chute (in our experiment 34 persons descended smoothly
one after the other in 1 minute). Smooth and non?clogging
descent is possible. Even if clogging should occur there is
no worry at all about the strength of the chute which can
withstand a load upto 7,200kg(15,870 lbs).
CHUTE WEIGHT
The weight of the chute is 1.4
kg per 1 meter (15 ounce per 1 foot).
STRENGTH
All the parts and components
such as the installation bolts anchored on the building floor,
installation or fitting metal parts, chute hardware, chute
main body and the joints are designed and, made to withstand
a sufficient load and do not deform up to the force of 1,000kg
(2,200 lbs).
Therefore, the escape chute is strong enough for escaping
persons in succession one after the other.
FLAME RESISTANCE
There are some good flame resisting
fabrics such as glassfiber cloth, carbon fiber cloth etc.
However these fabrics do not have sufficient capacity for
wear, abrasion, bending friction and so they are not suitable
for our chute cloth.
There are some fabrics which
have some flame resisting capacity but their prices are about
ten times or so as compared with those of ordinary fabrics,
which prevent us from using them for our chute.
We, therefore, use polyester
cloth treated to give flame resisting capacity for our outer
chute cloth. This cloth is flame resisting, is sufficiently
strong and the price is reasonable.
DURABILITY
We make our escape chutes using
the materials of the highest degree of durability selected
out of various materials so that our chutes are excellent
in durability, weather resistance etc.
