CENTRIFUGAL PARACHUTING SAFETY BRAKE

摘要

The "Centrifugal Parachuting Safety Brakes" is a system that allow quick evacuation from tall buildings in any emergency situation. The system constitutes of : A serious of gears (fig. 1 nn. 1-2-3-4); Brake-shoose rolling inside a steal cylinder aerated and cooled by heat dispersion openings. (fig. 1 n.5 - fig. 2 - fig. 3); Steal rope anchored to a roll (fig. 1 - n.6); Disk-brake of arrival to ground level (fig.1 - n.7); Activation system at end of ride (fig. 1 n.9); Ending in a stirrup anchored to a cement base on the ground level and in which only the cord passes through. Not the brake, which activates the still cord, attached to the shoes-brake of the disk brake (fig. 1 n.8). The recall system is activated automatically by the unrolling of the still cord. The system is mechanic and does not require any form of power energy or any special manpower (fig.4 - n.1). The unrolling of the steal rope and throughout a posterior gear to the roll but not the axon, automatically activates the recall system. Throughout this mechanism and in the stage of unrolling of the steal cord, the connection to the gear that in the inside host the return spring, is turned to make one revolution at every five revolution of the roll (fig. 4 - n.2). Therefore in the 50 turns of the roll the spring automatically reloads with 10 revolution on itself. In phase of release, once the roll is free for rotator motion of rewind been equip with a system of escape for relinquish from the gears and shoes-brakes which would impair the proper velocity. The return spring throughout the two gears connected to the roll brings it back to the starting station. At which point the subsequent opening blocks the bell to avoid that the roll rewinds. In the event of connection to the basket the entire system is blocked by the arrival of the sustaining part of the basket blocked by the compact pivot (fig. 5). It is important to specify that, as soon as the "L" shaped hairpin is activated by the weight at the end cord (fig. 4 - n.3) if in the belt system or the safety basket system, immediately and automatically a cord winded in a container furnished with an external winding crank (fig. 4 - n.4), is freed. This cord is in agreement with the "L" shaped element and at extreme end has attached a weight which stand out of the container soon after the opening of the underside door and predisposed in 30 meters so that whoever, during the stage of automatic rewind of the system, pulling this cord can stop both the safety belt or the safety basket at his/her window.
