Everyone knows that in big cities, for reasons of space, the present trend is to build very high buildings or skyscrapers. Unfortunately, when some serious troubles occur, like the loss of electricity, or proper disasters like fires, earthquakes or other, people must quickly leave the building. In these circumstances, often some unexpected and insuperable events arise, for example lifts out of service, parts of stairs that are blocked or even fallen down. Unfortunately in those cases nobody can help us, at least in a short while, and often real tragedies occur, like people who, in the grip of fear and despair, throw themselves out of the window or balcony slumping on earth. In order to avoid, or at least curb, these accidents, Mr. Landi Ettore
has invented a very useful accessory, the "Intelligent Pulley". As a matter of fact, with this extraordinary apparatus, any person, even the most inexperienced, could move down from a window without problems, by using a makeshift hooking. Inside this invention there is a special mechanism capable of automatically adapting to the weight of the person using it, making him/her go down to earth quietly and at a prefixed speed. This mechanism is composed by two jaws, like the ones of motorcycles, which are joint by two bolts and a spring; at the centre there is a catch that in its turn, according to the weight, exerts more and more pressure on the jaws in such a way that they stop a rotor where a long steel cable is wound, so bringing down, at the same speed, either a strong or thin build person. The "Intelligent Pulley" is totally manufactured in plastic in order to make it lighter, so that it might be used by everyone. Its inventor thinks that, once on sale, this useful apparatus might be supplied to every tenant leaving at the highest floors of buildings and skyscrapers, making it a very widespread accessory. This revolutionary apparatus has been even experimented by a company of firemen with great results.
