Description

Auf elektrischem Wege zu öffnendes Schloß. Zusatz zum Patent 337307# Durch das Patent 337307 ist ein auf elektrischem Wege zu öffnendes Schloß geschützt, bei welchem neben den Kontakten für den Öffnungsstromkreis des Schlosses noch eine Reihe von wahllos angeordneten Kontakten vorgesehen sind, welche die Endpunkte von Alarmstromkreisen darstellen.Lock that can be opened electrically. Addition to patent 337307 # A lock that can be opened electrically is protected by patent 337307, in which, in addition to the contacts for the opening circuit of the lock, another Series of randomly arranged contacts are provided, which are the endpoints of Represent alarm circuits.

Der Öffnungsstromkreis und die Alarmstromkreise besitzen meistens, insbesondere wenn die Klingel oder das. Transparent sehr weit von der Tür entfernt ist, verschiedenen Widerstand, Spannung oder Stromstärke, wodurch es Unbefugten möglich ist, durch Meßinstrumente die beiden Gruppen von verschiedenem Widerstand herauszufinden. Ton den herausgefundenen Gruppen weist die eine Gruppe nur einen Stromkreis mit einem bestimmten Widerstand, die andere Gruppe dagegen mehrere mit einem anderen, jedoch untereinander gleichen oder fast gleichen Widerstand auf. Ersterer ist dann gewöhnlich der Öffnungsstromkreis, der nur zu schließen ist, wenn das Schloß in Tätigkeit treten soll. Auch hinsichtlich Spannung und Stromstärke können sich die beiden Stromkreise in der gleichen Weise unterscheiden.The opening circuit and the alarm circuits usually have especially if the doorbell or the transparent very far away from the door is different resistance, voltage or amperage, making it unauthorized is possible, by measuring instruments, the two groups of different resistance to find out. One group only assigns one group to the identified groups Circuit with a certain resistance, while the other group has several another, but equal or almost equal resistance to each other. The former is usually the opening circuit, which can only be closed when the lock should come into operation. Also in terms of voltage and amperage the two circuits can differ in the same way.

Vorliegende Erfindung besteht nun darin, daß die beiden Stromkreisgruppen so gewählt werden, daß die Spannung, die Stromstärke oder der Widerstand, gemessen an den außerhalb der Tür liegenden Kontaktstellen des Öffnungsstromkreises, ebenso groß ist wie der an den ebenfalls außerhalb der Tür liegenden Kontakten zu messende Widerstand, die Spannung oder Stromstärke der Alarmstromkreise.The present invention is that the two circuit groups be chosen so that the voltage, current or resistance is measured at the contact points of the opening circuit outside the door, as well is as large as that to be measured on the contacts also located outside the door Resistance, voltage, or current of the alarm circuits.

Zu diesem Zweck sind im Offnungs- oder in den Alarmstromkreisen oder `in beiden z. B. Ausgleichswiderstände zur ilerbeiführung des gleichen Widerstandes bzw. Spannung vorgesehen, welche zweckmäßig verstellbar sind. Ebenso können, um an den Kontaktstellen für den Öffnungs- oder für die Alarmstromkreise die gleichen Stromstärken zu erhalten, besondere Ausgleichsstromquellen in den beiden Stromkreisgruppen angeordnet sein, die entweder ganz oder teilweise zu- oder abgeschaltet werden.For this purpose are in the opening or alarm circuits or `in both z. B. balancing resistors to supply the same resistance or voltage provided, which are expediently adjustable. Likewise, in order to the same at the contact points for the opening or for the alarm circuits To maintain currents, special compensation current sources in the two circuit groups be arranged, which are either completely or partially switched on or off.

Auch können die Haupt- oder die Ausgleichsstromquellen in ihrer Stärke veränderlich gestaltet sein.The main or the equalizing current sources can also vary in their strength be designed to be changeable.
