Abstract

An elevator 19 with provision for emergency use is guided along chains 7 fixed by hooks 1 to the ends of a lift shaft. The elevator is normally powered by a direct current motor 10 moving chains 18 via gears 11 - 16. In an emergency the lifts can be moved to the next floor using a manual handle and crank 25 mounted in the cab. The lift is balanced by counterweights (23, Fig. 8) and cable 24. The cab has a casing 9 for storing the chains during movement. The elevator is preferably for buildings greater than 7 floors. <IMAGE>

Description

ELEVATOR This invention relates to elevators.

This invention provides a load-carrying cabin movable along a substantially vertical path; motor drive means for moving the cabin along said path; and manually operable emergency drive means disposed within the cabin for moving the cabin along said path.

This invention also provides an elevator cabin movable by motor drive means along a substantially vertical path, the cabin comprising manually operable emergency drive means disposed within the cabin for moving the cabin along said path.

1) At present there are used elevators buildings higher than 7 floors. If there would be a fire alarm and the electricity suddenly would brake down there would be no way to move up or down. The people being stuck would not find a door to escape. To overcome this problem it is necessary to use a direct current machine. If the batter ror direct current would be empty and there wouldatt remain any current than you can help yourself using the own manpower. Than you can escape and save your life. Because of that need, which has been described above there has been constructed wind of elevator for both, for the use of direct current and for the use of manpower. That is a main purpose of an embodiment of the invention this invention.Using X in projects and in transportation it can show us its efficiency.

Its advantages are an easy production, a cheap cost of production, reliable safety, using direct current as driving force and the possibility of moving up and down by using your own manpower. You don't depend on any external forces and it is easy to use.

2) n factories usually there are used cranes to lift up heavy things. But it is only used for lifting goods. o, or construct on has been changed into an elevator to transport people using the same physical principle and the same crane. And it is employing two chains or four chains or many chains working at the same time and the up and down movement is synchronic. In this way it can move smoothly. And if there happens a problem with one of these parts you don't have to worry. It can reach the ground safety. (See Fig. 3, 4, 5, 6, 7, 8) On the Fig. one unit has two chains. If using 4 chains, than four chains will be two units. The installation on the Fig. is synchronic. Of course, if there are two or three units than they also can let it moving up and down synchronic.

3) At present, when lifting goods with the crane it will be installed on the scaffolding. The goods on earth than will be lifted up. Our construction now has put the crane on earth. For up and down lifting the hook of the chain will be fixed at the upper end of the scaffolding. That kind of use has never been existed before. Only in this way the people inside the elevator can freely control the up and down movement by their own. (See Fig. 3, 4, 5, 6, 7, 8) 4) Using two units or many together the elevator makes use of mechanical principles. The axle lets the elevator reduce resistance. It further makes use of the principles of movement transmission of the gear wheels and combines the positive and negative rotation of these wheels.And it lets it moving up and down synchronic.(See Fig. 5, 6, 7) But the originally used chain has to be replaced by the gear wheels. (See Fig. 1, 2, 3, 4, 5, 6, 7) 5) The important gear wheel (12) rotates as one pair. Each unit has another one placed on the opposite side. The gear wheels are rotating in contrary. It is an easy construction which lets the chain rotate synchronic.

6) The direct current motor has a battery, transformator and a rectifier which works as a recharger and a contact breaker. The electrolyte in the battery can keep good effectivity. In easy words, while in use you will have energy at any time. After using t, charging begins immediately. After charging the contact breaker will cut of the power supply immediately. You don't need to charge again. It keeps the battery for a whole life use and it keeps it save. That is something what has been used in cars and at other places since a long .ime.

7) If the battery is empty and if there is no power you can use the manpower and take the crank to move the elevator up or down. This kind of construction is especially made for the use in urgent cases, for example if there is fire alarm or power failure or there is simply no energy. Because its working with direct current or manpower it is possible to leave the elevator save. And the lamp and the ventilator inside of the cabin can be also used with direct current. So, if suddenly the energy brakes down, that is no problem unless the battery is empty.

8) There is needed a room for the chains. (9) Every chain has its room to lay it aside. This room is in a downer part of the elevator. So, every chain is separated from each other and is put orderly. That prevents the chain from blocking.

9) While using the elevator there can also be used two machines or more machines to drive it. For moving down one machine will be enough. You should pay attention to it when you use the switch. A diagram for the details is not necessary. That is also a common technique.

10) Our diagram doesn't show the cabin and the covers of the gear wheels and chains.

11) The chains of the elevator should be fixed on the scaffolding, which can bear the whole weight of the elevator. Besides the old use of the hooks (1), (2) there has been made a further support to fix it save. (5) There are certain screws to fi the crane. (5) (See Fig. 5) 12) If the elevator is used to transport people in high buildings there must exist a rail and a roller. (22) so that the elevator moves up and down along a straight line.

13) If the elevator is used for ransportation of people in high buildings there should be installed a weight for balance and it should hang at a steel wire to reduce the motive power of the machine.

(See Fig. S) 14) If the elevator is used for transportation of people in high buildings there can be installed a switch for moving the elevator and the doors automatically. The driving power comes from the direct current or from manpower. So, it is very easy.

Summing it up there is to say that a embodiments of is to technique ofchis invention1 use the cranes oppositely.

embodiments of That is a characteristic of' this invention.

A significant feature of embodiments of the invention is the use of the cranes which are oppositely placed. No one thinks of it. But once this counter-intuitive realisation has been made, it is relatively straightforward to produce an embodiment of the invention. For example: if the crane originally lifted 1.5 tons, so the opposited one also should lift 1.5 tons. However, no one has thought of this principle.

The invention will now be described by way of example with reference to the accompanying drawings. in which: Figure 1 shows the front side of the chain.

Figure 2 shows the side of the chain.

Figure 3 explains the two chains and their unit and shows where they are placed.

Figure 4 explains the unit and it's two chains after improving and the Figure shows where they are placed.

Figure 5 explains the installation of the elevator and the chains.

It makes use of tne physical functions at the crane and the gear wheels. So it supports the movemen: and ets the people inside the elevator being able to get in or out when ever they want and lets them control the up and down movement of the elevator.

Especially the oppositely installation in the crane, the fixing of the crane hook at the upper enc vithout wobbling. And wherever people want to move the elevator than the cabins moves according with it
