PORTABLE MECHANISM FOR GRAVITY LOWERING OF PEOPLE AND CARGOES FROM HIGH ALTITUDE WITH AUTOMATIC SPEED CONTROL Russian patent published in 2019 - IPC A62B1/14 

FIELD: transportation.

SUBSTANCE: invention relates to means of moving loads under action of gravitational force. Portable mechanism for gravity lowering of people and cargoes from high altitude with automatic speed control comprises a body, a drum with two gear wheels rigidly fixed in its middle part and a rope fixed between them on the drum, two support bars fixed on body opposite to each other in one horizontal plane with satellite gears installed on them, having gear connection with gear wheels and installed in one horizontal plane by braking devices, each of which consists of shaft with splines made in its middle part for provision of gear connection with satellite gear, two fixed on shaft on outer side of end part of each gear wheel of brake blocks, in each of which on the side of external side surface of each gear wheel there is a brake disc installed on the shaft with possibility of axial movement along the shaft splines for contact in the phase of braking with the external side surface of the gear wheel, centrifugal levers fixed at equal distance from each other by means of axial joints on fixed on shaft coupling, connected by rods with brake disc, wherein to ensure retention of brake disc in neutral position at normal descent rate each centrifugal lever is connected by spring with coupling.

EFFECT: invention can be used in extreme situations for evacuation of people and cargoes at high altitude.
