<p>A new method of, elevator in which multiple cages on each floor are connected by conveyor chain which lifts all cages on one side in upward direction and lowers all cages on other side in downward direction, thereby giving very huge efficiency of moving people up and down very fast. In this variations are possible of having either alternate cages or one cage in 3 floors on 1 in 4 floors etc. and the number of cages on the chain will decide the level of efficiency as compared to single cage at present. The entire chain having all cages is moved by sprockets on top & bottom. When any cage has reached its destination it stops & that door is opened. Due to timer setting door closes automatically and chain moves again. When chain stops, all the floors will have two cages facing the floor, one for upward movement and one for downward movement. At any time at any floor if person wants to go up or down he has to only press a proper button outside and almost instantly the door of cage available on that floor opens and he (or they) go inside. After pressing suitable buttons inside the cage, the whole chain starts moving tiU that cage comes to its destination and stops, Variations in above(A)2 ducts are side by side and chain links are connected at front and back of the cage. Here the door will be in two parts and cage will have vertical partition. (B) The cages are not connected by chain but they are independently driven by either motor or fuel engine etc.and they move up and down with the help of rack, pinion and brake. At the top, the cage can be either pushed by hydraulic or pneumatic cylinder from left to right or allowed to be inverted (C) The cage is in form of piston, which is moving in a vertical cylinder. The air above the cage is removed with the help of steam, ether vapour etc. and further condenses with the help of shower /cooling water which creates vacuum and air pressure pushes the cage upward at very high speed. The lowering of the cage due to gravity is controlled by normal chain, gearbox and wire rope mechanism.</p> |
