本発明は火災等の際に高層ビルから降りるためＣ１使用
する緩降装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gradual descent device C1 used for descending from a high-rise building in the event of a fire or the like.
従来の緩降装置は摩擦ブレーキを用いているため、発熱
し多人数が使用すると、高温となり、触れると危険であ
り、また場合によっては使用不能となる。Since conventional descent devices use friction brakes, they generate heat and, when used by a large number of people, reach high temperatures, making them dangerous to touch and, in some cases, rendering them unusable.
本発明はブレーキとして現根車を利用し、全く発熱しな
い緩降装置を得ることを目的としている。The object of the present invention is to obtain a gradual descent device that uses an existing root wheel as a brake and does not generate any heat.
本発明を図の実施例砿ニジたがって説明する。The present invention will be explained with reference to the embodiments shown in the drawings.

讃阜２８より小であり、出力軸３２に固着されている。The rotation of the pulley 10 is through its shaft 22 and the gears 24, 26
．． It is transmitted to the transmission consisting of 28.30. gear 24
- It is fixed to a shaft 22 that rotates together with the Boo IJIO. The gear 26 meshes with the gear 24, and the number of teeth is -
It is smaller than car 24. The gear 28 rotates together with the gear 26. The gear 30 meshes with the gear 28, has a smaller number of teeth than the gear 28, and is fixed to the output shaft 32.
したがってこの変速装置によりプーリｌＯの回転は増速
され、出力軸３２に伝達される。Therefore, the speed of the rotation of the pulley lO is increased by this transmission and transmitted to the output shaft 32.
