Abstract

An alarm appendage intended to be applied to a telephone, which is programmable to, after effecting a call button (5), call at least one programmed telephone number in question. The invention is distinguished by one, towards the call button (5), directly or indirectly pretightened spring element (1), which is temporarily lockable in a position at a certain distance from the button (5), and which pretightened spring element (1) is activated through releasing it from its locked position via an unintentional influence on the effecting instrument (6), at which the element (1) with a spring pressure presses the call button (5) for calling the programmed telephone number in question.

Description

Mechanical alarm appendage for telephone

The invention in question has reference to an alarm appendage designed to be applied to a telephone, which through influence by a call button calls an in advance programmed number, at which the one who is called gets an indication of that the alarm is sounding.

Alarms through electronically initiated calling with an ordinary stationary telephone has existed on the market for a long time, but have been relatively expensive.

The purpose of the invention in question is to simply produce an alarm, with an ordinary mobile telephone in combination with a mechanical activator.

The mobile telephone in combination with a mechanical activator forms an alarm which easily can be installed almost anywhere, in boats, houses, cars, caravans etc via a light detector _r a sound detector, an electric switch, a trip wire, a mechanical switch etc.

If you let the activator switch on the telephone as well in connection with calling, the telephone will not before then consume power and the battery can maintain its capacity for a long time. If you are connected to net power the capacity of the battery is of no importance. The characteristics of the invention are mentioned in the following patent demands.

Thanks to the invention an alarm appendage is now produced, which in an excellent way will fulfill its purpose and at the same time be both easy and cheap to manufacture. The alarm appendage is in one very simple operation mounted on a mobile telephone or an ordinary button telephone.

In this connection you programme the number you wish the telephone to call at an alarm. After this you place the pretightened spring element above the call button and locks it temporarily in this position (cock the alarm) , which locking is released when the effecting instrument used to release the element is activated (the alarm is alerted)

The effecting instrument used to release the pretightened spring element consists of something which is connected to the protected object and can aslo consist of a photocell which via an electromagnet releases the pretightened spring element from its locked position, so that the call button of the telephone is pressed down.

The risk of a false alarm is non-existent if you have installed a number presentation service. It will tell the identity of the caller.

The number presentation service also has the advantage that you afterwards can find out if the alarm has sounded, in those cases you haven't had continuous control of the telephone and for certain telephones also the time for the alarm.

The invention is more closely described below by some examples of design referring to the attached drawings, on which

fig. 1 shows a first design of an alarm appendage according to the invention

fig. 2 shows a second design according to the invention

fig. 3 shows another design according to the invention

As will be seen by the design shown in fig. 1, it consists of an alarm appendage, which has a, with a coil-spring 2, pretightened spring element 1 in the shape of a mouse-trap bow 4 with a pad 3 , which effects the call button. By this design an effecting instrument 6 consists of an angleplate 7 which locks a stop bar 8.

Exterial influence through a, to the effecting instrument 6, connected wire 9 or such releases the pretightened spring element 1, which via the pad 3 presses the call button 5.

The design shown in fig. 2 consists of the pretightened spring element 1 in the shape of a mouse-trap bow 4, on whose transverse bow part 10 over the call button 5 a "rider" 11 is arranged, which in its turn by means of a thread 9 or such is tiltable against a call button 5 for releasing the alarm.

The design shown in fig. 3 consists of a pretightened spring element 1 which can be placed and locked in a position at a predetermined distance from the button 5. The, be means of a rubber band, pretightened spring element which in the example shown consists of a bolt instrument 12, can be activated through a release from its locked position be means of pulling out a locking pin 13 via a thereby fastened thread 9 or such.

Using the alarm appendage you do like this: You place a mobile telephone, could be an old model as well, but with a battery in good condition or with the net power connected, in the alarm appendage and adjust its position with e.g. a rubber band. In this connection you dial the telephone number to which you wish the telephone to send the alarm, preferrably the mobile telephone you are using yourself. You adjust the pressure point of the pad towards the telephone by pushing the pad horisontally on the traversing bow and vertically through changing the position of the phone.

After that you make an extra control of the function, that the pretightened effecting instrument pushes the right button, the call button, and that calling takes place. After that you cock the alarm appendage and with a thread or such you connect with an external releasing power, often the object or the phenomenon for which you want to install an alarm.

In the design with the bolt instrument the alarm appendage is astened directly above the call button after programming the telephone number in question, and for that reason no further adjustment of the position is needed.

When the alarm is sounding you get a call and the number presentation service tells that the alarm is alerted and even which, in case of several. If you on your receiving telephone have put in the telephone number of the alarming telephone in advance and made an identity determination, the display will show e.g. "ALARM BOAT" and you can call the neighbours or the police and immediately take appropriate measures .

If you use so called cash card, you don't have to bother about a unwanted call cost in case of theft of the larming telephone.

Claims

Patent requirements

1. An alarm appendage designed for applying on a telephone, which can be programmed to, after effecting a call button (5) call at least one actual, programmed telephone number, distinguished by one towards the call button (5) directly or indirectly pretightened spring element (1), which is temporarily lockable in a position at a certain distance from the button (5) and which pretightened spring element is activated through releasing it from its locked position via unintentional influence on an effecting instrument (6) at which the element (1) with a spring pressure presses the call button (5) and calls the programmed telephone number in question.

2. An alarm appendage according to patent requirement 1, distinguished by the pretightened spring element (1) consisting of a bow (4) with the form of a mouse-trap bow (4) on whose transverse upper bow part a pressing element (2) is arranged and can be slided.

3. An alarm appendage according to patent requirement 2, distinguished by the pretightened spring element (1) consisting of a bow (4) with the form of a mouse-trap bow (4) around whose transverse bow part an towards the call button (5) a tiltable pressing element (8) for alerting the alarm, is arranged and can be slided.

4. An alarm appendage according to patent requirement 1, distinguished by the pretightened spring element (1) consisting of a spring steel with the form of a mouse-trap bow (15) on whose transverse bow part a pressing element (3) is arranged and can be slided.

5. An alarm appendage according to patent requirement 1, distinguished by the pretightened spring element (1) consisting of a bolt instrument (12) which is temporarily lockable, e.g. with a locking pin (13) in its activated position above the button (5) and which locking pin (13) is connected to a wire (9), by which the locking pin is extractable for releasing the bolt instrument (12) and pushing the button (5), at which the alarm is alerted.
