PATENT OFFICE.

When operating elevators through several floors, it is necessary that in each of them The respective position of the elevator car can be seen on the floors.

For this purpose are so-called. Stroke indicators in use, which are switched on corresponding translations are set in motion by the elevator machine.

These lift indicators usually consist of a rope on which in Marks are attached to each storey, which are on a scale indicating the position of the Adjust the elevator accordingly.

These types of stroke indicators have the disadvantage that the ropes stretch or grind on the pulleys and as a result the marks on the ropes with the marks at the Scala respectively. do not match the respective positions of the elevator.

The purpose of the present invention is to remove the unreliable mechanical stroke indicator to replace with electric.

As can be seen from the accompanying drawing, there is a panel T on each floor, which has as many signal flaps as the elevator has stopping places, and a signal flap with the inscription "Elevator is running".

The individual flaps are provided with an electrical reset.

The action on the flaps for the journey takes place in the following way.

A current closer UF with two contacts is attached to the elevator machine, which is moved electrically or mechanically.

In the accompanying drawing it is assumed that the elevator car is in the basement.

As soon as the elevator is set in motion, the contact lever of the normally open contact UF slides over contacts 1 and 2.

Contact ι is the feed line for the reset magnets the flaps for "elevator is running", which are switched one after the other on all panels are.

Contact 2 is the supply line for the adjusting magnets of the flaps "elevator is running", which of all panels are also connected one after the other.

When the contact lever is touched with Contact ι, the circuit of the reset magnets is activated closed, but without effect because the flaps are reset anyway.

When the contact lever is touched with Contact 2, the circuit becomes the setting magnets closed and the flap reveals the label "Elevator is running" to the eye.

As soon as the elevator machine is switched off again, the contact lever of the normally open contact UF slides back into its previous position via contacts 1 and 2 and, when contact 1 is touched, closes the circuit of the reset magnets, and the flap that falls back conceals the label "elevator is running" again.

The action on the individual flaps for the holding places takes place as follows.

At all stopping places there is a slrom closer UH with two contacts and also a lever SH .

The lever SH, which can also act on the locking of the elevator doors, is kept constantly in a certain rest position by a spring b and only when the elevator car is passing by a nose with a slide N attached to the elevator car, which acts on the roller r, brought out of its rest position determined by the spring.

The supply line for the reset magnets of all flaps in all panels is connected to the contact ι of all current closers UH.

The reset magnets are, as can be seen from the drawing, in the individual panels one behind the other, the panels connected in parallel to a collecting line, which is connected to all contacts ι of the current closers UH.

The supply line for the setting magnets of the individual landing flaps is connected to Contact 2 of all the current closers UH.

As can be seen from the drawing, the floor flaps of the same meaning in the panels are switched one after the other.

The effect of the device is as follows:

When the elevator is in the basement, as indicated in the accompanying drawing, it is on the Tableaus on all floors, the signal flap for "basement" is set and it can be seen that the elevator is in the basement.

As soon as the elevator is set in motion in order to travel to the first floor, the "Elevator moves" flap on all panels is primarily set by the current closer UF, as already described earlier.

As soon as the nose attached to the elevator car with slideway N releases the lever 5 H , the lever returns to its rest position by the action of the spring.

At the same time, the contact lever d of the normally open contact UH , which is connected to the lever SH by a rod, slides over the contacts 2 and ι.

When contact 2 is touched, the circuit of the setting magnets of the flap for The basement is closed, but has no effect because the flaps are on the basement anyway are set.

When the contact 1 is touched, the circuit of all the reset magnets is Floor flaps closed and as a result, the flap for the basement is reset.

When the elevator car arrives on the ground floor, the lever SH is pushed back by the nose with slide .ZV attached to the elevator car. At the same time, the contact lever of the normally open contact UH slides over contacts 1 and 2.

When contact 1 is touched, the circuit of all reset magnets is closed, but without any effect because the flaps are reset anyway.

When contact 2 is touched, the circuit becomes the setting magnets for the ground floor closed in all tableaus and the inscription "Erdgeschofs" becomes visible.

If the elevator stops on the ground floor, then all the flaps "Elevator is running" are reset by the current closer UF and, as a result, only the flaps "Ground floor" are visible on all panels.

The just described mode of operation of the device is now repeated during the further movement of the elevator for each of the existing floors in a corresponding manner.

Claims (2)

Patent-to sayings: 1. A device for displaying the respective position of the elevator car from Electric passenger and freight elevators, characterized by the arrangement of panels at the stopping places, as well as from current closers with two contacts themselves, which are attached to the elevator car by one Noses are moved so that, depending on the direction of movement of the elevator, those connected to the contacts Signal flaps either cover or reveal the inscription behind them, and characterized by the arrangement of a special signal flap in each panel, which indicates whether the elevator is in motion and which is electrically powered by a normally open contact connected to the elevator machine or is moved mechanically. 2. An execution of the current closer according to claim 1, characterized by a lever (SH) which is held in its rest position by a spring (b) and the contact lever (d) via the contacts (1 and 2) by a connecting rod moves if the guide pulley (r) is pushed back by the nose (N). 1 sheet of drawings.
