DE4302164A1 - Signalling arrangement esp. for door=bell installation with loudspeaker - Google Patents

Abstract

The bell pushbutton (10) or similar electronic or mechanical actuator is connected by two wires (12,13), one passing through a transformer (14), to the bell (16). Branches (18,19) from the principal wiring lead to a tape recorder or similar analogue or digital signal storage device (20) from which a signal line (22) runs to an optical indicator (23) near the bell pushbutton.The resident can hear the message through an internal loudspeaker (29) or call up the recorded message subsequently from the memory, which may be duplicated for two-way conversation.

Description

The invention relates to a signal device with electri main wires for connecting a signal generator with a Triggers and with a line assigned to them with Mi krofon and loudspeakers, in particular a doorbell system with loudspeaker device.

A visitor wants in the absence of the visitor He often finds the bell ringing, for example the following handwritten note: "I'll be back at 3pm back ". Since everyone can read this information, it is at the same time a good tip for burglars. Per se well-known intercoms, with those from the resident to the outside asked who is there are in the absence of the Resident cannot be used.

The inventor was aware of this state of the art set the goal, the identified defects especially in the door eliminate bell systems.

The teaching leads to the solution of the problem seen by the inventor of the independent claim - the sub-claims give it favorable designs.

According to the invention there is at least one tone in the line Drawing device or the like. Memory integrated, thanks to which the Visitor is able to leave a message to the resident, but also the resident the user to the request can let speak into the facility. Such informa tion, for example, does not let a burglar see whether the resident is present or not.  

Automatic intercom systems of this type are not known. Though there are automatic answering machines, but they are like that are constructed so that for the purpose seen by the inventor, an automatically recording and answering intercom creating at the front door are not suitable. The Telephone answering machines must have a two-wire line Call signal, the incoming signal and the outgoing Process signal. An automatically recording and answering intercom but the separate bell Evaluate the line and then the announcement in the voice line feed. After the announcement, the listener line must open be made. A connection to an answering machine an intercom would not perform any of the required functions fulfill.

According to the invention, the system is started at the push of a button tet, which is a simple version of a device that a Auf recording the visitor's text. The visitor gets through an acoustic or optical display indicates that the device is ready to record shaft shown.

An extended device according to the invention consists of an adaptation circuit on the bell, the handset sound speaker, the handset microphone and the voice output memory and the recording memory as the heart.

The system is preferably designed so that it has a or record multiple visitor texts that the resident or operator can then listen at any time.

The speech or sound memories can consist of one or more other audio recording tapes, one or more digital Storage or other storage systems exist.  

According to the invention, the system becomes the visitor after the start present a text or other sounds acoustically and then asked him - "I'm very busy. Come back at 3pm. Enter name and reason Of your visit. Please speak now "- submit. Then visitor text or noises are recorded.

There is a possibility of completely eliminating the facility House intercom to install so that they ge independently can be used.

In an advantageous further embodiment of the circuit can use a microprocessor and a matching circuit for the phone can be integrated into the device. Thus one automatic door intercom with the possibility offered record separate announcements for telephone and door or to play.

So it is an automatic sound recording capable of a sound notification by a trigger mechanism records or stores from the outside door. Of the External door sound message goes one or more internal door- Sound announcement (s) in advance. After the latter can multiple sound messages are recorded.

In the sound recording system according to the invention is a part from her in front of the final door of an apartment, a house, Gar tens or offices installed and the other part behind this Final door.

According to a further feature of the invention, this system by any mechanical or electronic devices to be triggered.  

Further advantages, features and details of the invention he give more preference from the following description Exemplary embodiments and with reference to the drawing, the Figu Ren several circuit diagrams for different versions play a system according to the invention.

The bell button 10 - or another electronic or mechanical trigger for signaling - a doorbell bell system is connected according to FIG. 1 by two wires 12 , 13 of a main line - one of which contains a transformer 14 - with a signal transmitter 16 , for example a bell. The main wires 12 , 13 are connected via two wires 18 , 19 to a memory 20 , such as a tape device or some other analog or digital device for storing signals.

A signal line 22 for a bell-type optical display 23 goes out from the memory 20 , as well as a line 25 for an outside microphone 26 and a line 28 for an inside speaker 29 .

If the bell button 10 is pressed, for example, by a visitor, the visual display 23 prompts him to speak into the external microphone 26 . This picks up the visitor text and passes it on to that memory 20 .

A house occupant or operator listens to the visitor's text through the interior loudspeaker 29 - for example a handset of an intercom - or he can call it up from the memory 20 .

In a device according to FIG. 2, an inside microphone 30 , optionally integrated in the handset, is provided on the inside or on the user side, which is connected via a microphone line 31 to a storage group consisting of recording memory 20 , voice output memory 20 a and controller 21 ; these voice or sound memories 20 , 20 a can consist of one or more sound recording tapes, one or more digital memories or other storage systems.

The device has on the visitor side in addition to the Klin gelknopf 10 - or another mechanical or electronic trigger such as infrared or microwave detector - and the outdoor microphone 26 still has an external speaker 32 , which is also connected to that storage group 20 , 20 a by means of a speaker line 33 is.

After the signal has been triggered by pressing the bell button 10 , information for the visitor is played by the external loudspeaker 32 from the memory 20 . Upon request, the visitor can then speak his or her visitor's text into the memory 20 a through the external microphone 26 in the manner already described. For this reason, the memory 20 in FIG. 2 is between the external microphone 26 and the internal loudspeaker 29 , but the memory 20 a is between the internal microphone 30 and the external loudspeaker 32 .

In Fig. 3, the outer microphone is included with the outdoor speakers in a single unit 36, internal speakers 29 and 30 in one unit in nenmikrofon 38th The lines 37 and 39 are on the connecting cords 40 and 41 between SpeI cher 20 and a connected 20 and memory 20 and 20 a.

The operator can start the listening process by pressing a button; then the information about the interior speaker 29 is played for him from memory 20 a.

In Fig. 4, the memories 20 a and 20 b are combined with a controller 43 in a unit 44 ; the latter is connected with lines 46 , 47 to additional wiring harnesses 48 , 49 , in which a switch 50 is located. Wiring harness 48 leads from an internal speaker 29 a to an external loudspeaker 32 , wiring harness 49 from an internal microphone 30 a to an external microphone 26 a.

The embodiment of Fig. 5 includes an assembly 45 of four memories, and a controller 43 which is connected to an In nenlautsprecher 29 and an inner microphone 30th With 52 one of the systems described above is shown symboically, so a house intercom that connects to the unit 45 via an adaptation electronics 54 . In Fig. 5 to the left of the unit 45, a telephone adaptation electronics 56 is indicated with lines 58 leading to a telephone.

So here are a microprocessor and one Adaptation circuit for the telephone integrated in the system with the possibility of separate announcement texts for the phone and play or record the door. The operator must the listening process for the Put visitor text into operation, then the memory the information played through the interior speaker.
