A plurality of weights 1 having one end pivoted 13a on a speed increasing rotary plate 4b having a boss 4a around the speed increasing shaft 2a of the speed increasing machine 3.
3 and a brake drum 12 provided on the outside form the centrifugal brake 4, and the braking force is varied stepwise for each weight 13. This stepwise difference is for each spindle 13
This is due to the difference in the weight of each type and the difference in the strength of the weight brake spring 14. Flanges 6, 6 are provided at both ends of the winding shaft 5 provided on the winding shaft 2, and a short cylinder 7 is provided to cover both the flanges 6, 6 and the outer circumferential space between them.
A wire rope winding space a is formed on the outer circumferential surface of the wire rope 19, and the wire rope 19 is wound in the space a and the wire rope 19 is wound through the wire rope take-out groove 7a formed in the short tube 7.
can be drawn out through the guide tube 15. This short tube 7 is fixed to the machine shop 1 in the rotating direction of the winding drum shaft 2, and the wire rope guide tube 15 is provided on the machine cliff 1 above the take-out groove 7a. To fix the rotating direction of the short tube 7, a protrusion 9 is provided on the outer surface of the short tube 7, and a winding 8 coaxial 2 is provided on the inner surface of the cliff 1.
The short cylinder 7 may be fixed by joining the joint groove 1 provided in the same direction with the protrusion 9, or by using a bolt inserted from the outside of the weight 1. In the figure, 11 indicates a speed increasing gear group of the speed increaser 3, 16 a wire rope guide roller provided at the upper end of the guide tube 15, 17 a mounting sheet for the cliff 1, 18 a human body mounting belt, 19 is a wire rope, 20 is a wire.
This is a hook provided at the tip of the loop 19. Therefore, in an emergency, when the belt 18 is attached to the human body 21 and the machine coating 1 is supported on the chest, the hook 20 is hung on the metal fitting 22 and the person steps down from the window, the wire rope 19 is unwound from the winding drum 5 due to the weight of the person. The winding drum 5 and the winding drum shaft 2 are slowly rotated via the speed increaser 3 and the centrifugal brake 4, so that the human body 21 can slowly descend to the ground.

At that time, when the weight is applied, the speed-increasing shaft 2a rotates rapidly, and the entire weight 1
3 comes into pressure contact with the brake drum 12 to brake it, and brakes the winding drum 5 via the speed increasing shaft 2a and the speed increasing machine 3 to gently brake the descent of the human body 21. When the descent is slowed down by this descent braking, the braking force by the weight 13 decreases step by step and the descending speed increases step by step, but due to this increase, the braking force by the weight 13 increases again step by step. slow down the descent. When descending, the user grasps the guide tube 15 with his hands and pushes the wall with his feet to support his body as he descends. The winding drum 5 and the flanges 6, 6 rotate slowly, but the short tube 7 does not rotate, and the wire rope take-out groove 7a fixed to the cliff 1 also has its position as shown in FIGS. 3 and 4. It is held in the position shown. When manufacturing the above-mentioned emergency descent escape device, the short tube 7 is inserted into the inside of the cliff 1 from the closed part of the airplane 1, and the short tube 7 is inserted between the flanges 6 and 6 of the winding body 5 built into the cliff 1. A wire rope 19 with a diameter of about 2 skins is wrapped tightly around the outer circumferential surface of the tube 5, against its elasticity, and the short tube 7 is in this state wrapped around the outer circumference of the flanges 6, 6. The space a is covered with the wire rope 19, and the wire rope 19 is filled with the wire rope 19, and the wire rope 19 tries to expand outward due to its elasticity and is supported by pressure on the inner surface of the short tube 7. . The wire rope 19 is pulled out from the wire rope take-out groove 7a through the guide cylinder 15 and the guide roll 16, and in this state, the closing lid 8 closes the entrance part and the bearing 22 provided in the closing lid 8 is pulled out. The above-mentioned emergency descent and escape device is formed by supporting the winding drum shaft 2. When winding the secondary wire rope around the winding trunk, it is necessary to make the diameter of the winding tube large because the winding is done according to the ballistic properties of the wire rope, which makes it difficult to make the device compact and lightweight. If the winding wire rope is formed to be small, the elasticity of the wound wire rope causes the inner flea of the winding wire rope bundle to be larger than the outer diameter of the winding drum, creating a gap between the winding drum and the winding wire rope east, and The outer periphery of the east side of the wire rope expands to the outside of the flange of the winding drum 5 and descends turbulently, causing a sudden drop and shock, which is dangerous, and the sudden increase and decrease in braking force causes repeated sudden drops and trailing drops. There was a defect that made it difficult to prevent the risk of impact.

本発明は上記欠陥に鑑みなされたものであって、本案は
上述のように横成したので急降下と綾降下との繰返し衝
撃による危険性を防止し得て安全性に富むと共に装置を
小形軽量に形成し得るばかりでなく製造容易な非常降下

The present invention has been made in view of the above-mentioned defects, and since the present invention has been completed as described above, it is possible to prevent the danger caused by the repeated impact of sudden descent and trailing descent, and it is highly safe, and the device can be made smaller and lighter. This has the effect of providing an emergency descent escape device that is not only formable but also easy to manufacture.
