Alarm device against burglary and theft

The invention relates to a device for determining a Breaking into a room, another limited space, by triggering an alarm signal.

Such devices are well known in the art. A detector mechanism is generally used for these, which responds to the movement of a locking element that closes access to a room or another room, A trigger mechanism is also used, which is shut down by authorized persons or the alarm is triggered can be picked up, both from the inside and from the Exterior of the closure element, and finally an alarm signal generator is provided which is close to or away located from the detector mechanism and the trigger is.

3Ü3 are two types of these devices one or the tripping device cannot determine what is happening inside the room or the limited space, and of which the other or its release device is realized either inside or outside the room.

In the latter case, the release device preferably refers to a lock or other analog device, which is independent and specially designed for this purpose.

is seen, or 3ie is represented by a locking element, which at the same time creates a possibility to block the closing element in its closed position.

will

3 in other known arrangements / if the lock once to the Closing the closing element is used and on the other hand as a triggering means of the device, in certain cases between a mechanical connection, for example a cable or a pull cord, is provided for this release device and the lock, however, this is relatively complex and expensive. In addition, if the closing element is a door of a room 13t or an analogous other room, this mechanical connection does not add anything to the appearance of the door.

In other cases the trip device is through a breaker realized, which consists of two fixed contacts located in the door frame, while the movable contact of the interrupter from the bolt of the locking device is formed, which is intended to close the locking element is. However, such an arrangement suffers from the considerable disadvantage that it is in place and "parts". installed must be calibrated. In the case of a door, it very often happens that the locking element has a clearance to the door frame has, which margin can be very different from one locking element to the other locking element. It follows that the arrangement can sometimes only be installed with difficulty by a person skilled in the art, whereby 95, however, is an article intended for a broad Audience and wide distribution is intended.

The object on which the invention is based is to provide the to eliminate IT disadvantages inherent in the state of the art.

The 3rfindung relates to a device for triggering an alarm in the event of a break-in into a room, through an enclosure demarcated area or other space that has a jingang opening has, which by a Ver ^ closing element, such as

2 0 9 8 4 9/0807

for example a door, a window or an analog device, is closed, which device can be locked by a locking device, such as a lock is, wherein a detector mechanism is provided, which is based on the responds to opening the closing element and controls a signal alarm generator, which is sent to the detector mechanism via a Trigger mechanism is coupled and offers the possibility to prevent the alarm triggering, whereby the trigger mechanism can be controlled by said locking device. The trigger mechanism consists of an electrical breaker, which can be controlled in succession, and from a pressure switch, the latter directly through the movable element can be actuated which element ensures the locking or locking function of the locking device.

By these features, a detector device is obtained, which is made compact and in which the connections between the various mechanisms are essentially electrical are made, and between electrical lines that can be hidden from view. The latch of the locking device Incidentally, did not take place directly during manufacture or when closing the electrical circuit or the electrical Circuit part.

The interrupter which can be operated one behind the other is preferred located in a housing which forms the locking socket of the movable element of the locking device, this 3 moving element on the push button switch of the breaker acts when the closing or locking device is in its closed position.

Further advantages and details of the invention emerge from the description of exemplary embodiments which now follows referring to the drawing. E3 shows:

? ig. 1 is a plan view of the alarm device according to FIG Invention in pre-binding with a bolt or a

Lock for locking a door;

FIG. 2 is a sectional view of the detector device from FIG Fig. 1 along the line 2 - 2 in Fig. 1;

3 shows a somewhat modified embodiment of the device according to the invention.

The apparatus shown in Figs. 1 and 2 is in this embodiment a door P, for example an apartment, assigned, the latter being a room to be protected or a represents protective enclosure. It should be emphasized that the subject of the invention does not apply to this embodiment limited, and that the space is either a room, an area delimited by an enclosure, a house, can be a single building, a drawer, a freezer or an automobile, etc.

Likewise, the locking element can not only be used on a door, but also be formed by a window, a portal, etc., for example.

On the door frame H of the door, a housing 1 is arranged, which has a twofold task. This housing is equipped with a locking socket for a locking device V, the latter is carried out in a conventional, classical manner, the bolt A being displaced in the horizontal direction can or slides.

The housing 1 also serves to protect a trigger mechanism and part of a detector mechanism 3

The locking device V preferably has two locking positions. In the first position the penetrates The bolt enters the locking socket of the housing 1, and the bolt gets into a gap or recess 4 which is conventional Way in the wall near the narrow side of the door P

209849/0 807

is provided. In the second position of the locking device V the bolt A penetrates even further into the housing 1, in such a way that its front edge 5 is in contact with a pressure switch 6 of the trigger mechanism 2 arrives.

The latter "consists of an electrical breaker of a well-known Type designed for sequential control or actuation. In other words, the breaker points two fixed contacts and one movable contact, the latter being able to assume two stable positions, which are consecutive or be taken one after the other with two successive actuations of the pressure switch 6. at In one of the positions the movable contact comes into engagement with the fixed contacts, while in the other position the breaker is open, and so the movable contact is lifted from the fixed contacts. The solid contacts this Interrupter are realized in electrical terms by means of two connecting screws 7 and 8, which are from the outside of the housing are accessible. The latter are by means of a screw and nut construction 9 attached to the housing 1.

For a better understanding of how the bolt works A of the locking device V is exerted on the release mechanism, is now referred to below on this mode of operation will be discussed in more detail. If the bolt is brought into the locked position twice from its position shown, it acts this latch on the push button or push button 6 and it opens and closes the breaker one after the other, or vice versa.

The detector mechanism 3 consists of an angle 10 which is not arranged in the housing 1, but on the The narrow side of the door P is attached in such a way that its bent edge 10a on the free end of an elastic metal tongue 11 can act, which in the horizontal position in the housing 1, i. H. on the rear side of the wall 12 is mounted. This' tongue preferably has a free, foldable one

209849/0807

2223R62

End, through which the effective range can be adjusted during assembly so that the gap between the Locking socket and the narrow side of the door are taken into account. The angle 10 is with the help of two screws 13 in position held, these screws passing through elongated holes 14 which are arranged to run in the longitudinal direction to be able to make an adjustment in the horizontal plane. The elastic tongue 11 is in the housing 1 in a similar manner with the help of a screw-nut construction 15, which extends through an elongated hole 16, so an adjustment in to be able to make horizontal plane.

3s it is possible in this way to adhere to the specified tolerances and gaps that are used for different doors or others Closing elements can occur, the positions of the angle 1C and the tongue 11 being adjusted.

the latter can act on a breaker 17 via a bent lamella 18 and a curved spring 19, whereby a rapid response of the interrupter is assured, a "puncturing technique that is well known in the art.

In the position of the door P shown in FIG. 2, the bent edge 1Ca of the angle 1C is supported by the elastic tongue 11, which in turn pushes the bent lamella 13, such that the movable contact block 17 a no connection or Has contact with the fixed contact 17b of the breaker due to the action of the spring 19.

If, on the other hand, the door P is open, the bent edge 10 a is out of contact or attack with the elastic Tongue 11, and the lamella 18 is released by the action of the spring 19. The latter also makes the moving contact 17 a against the fixed contact 17b, which happens very quickly is going.

The breaker or trip mechanism 2 and the breaker

209849/0807

17 3 are electrically connected in series and are connected to an alarm signal generator 22 via two electrical lines 20 and 21 connected, this circuit being illustrated in FIG. This generator is preferred in a particular Arranged at a distance from the door P, and between at a hidden place. This generator comes with a power source equipped that feeds a circuit that includes a siren 24 or other analog device, a relay coil 25, a closing contact 26, which can be actuated by the hot coil 25, and an interrupter contact 27 which, if necessary can be operated by a key. The make contact 26 is in series with the series circuit of interrupter and interrupter 17 switched.

According to a modified embodiment, the interrupter 17 and the bracket 10 can be replaced by a magnetically actuated breaker, for example by a type of breaker, in which the contact blades are arranged in a glass bulb, with the magnet on the door and the interrupter are arranged in the locking version, or in another suitable location.

The device according to the invention now works in the following way:

Suppose a person living in the room is in the apartment and wishes to go out and close the device sharpen. He opens the door and operates the locking device V in a conventional manner. At that moment the Breaker 17 closed, but breaker 2 is not closed, so that generator 22 is not in operation occurs. Closing the door brings about an opening of the interrupter 17, which is now outside the room the person located now wants to sharpen the device, with the riot A of the locking device V in the extreme Closing position leads, for example with the help of a key, "in a conventional manner to lock the door P in the

209849/0807

2223G62

Closing device V engages. At this moment the Latch on the pressure switch 6, and the breaker 2 is closed.

In order to keep the door P closed, the person concerned returns the bolt A to its first closed position.

If, under these conditions, a burglar tries to open the door, the angle 10 comes off the tongue 11, so that the breaker 17 is closed in the manner already described. At that moment the generator's circuit becomes 22 closed, the siren 24 sounds, and the relay coil 25 closes the contact 26. In this way the siren kept excited even if the burglar cuts the electrical lines 20 and 21, or if he the breaker within the housing 1 is destroyed.

However, if the person living in the apartment returns and wishes to enter the apartment, they can use the Key again disarm the device with the help of the key by inserting the locking device into its brings extreme closed position to open the breaker 2. The person can then unlock the door P and open the door.

It should be emphasized that the arming and disarming of the device according to the invention can also be done from within the apartment or spatiality can be carried out.

Fig. 3 shows a modified embodiment according to the invention, with the generator in the same housing as the trigger mechanism and detector mechanism 2 and 3 is located. This is a housing 28 with larger dimensions than the housing intended! and this housing is by means of a cover 29 closed, in which a lock 30 is provided. T * recognizes Incidentally, also that the housing contains all the elements of the Generatora contains. The lock 30 offers the possibility of opening the housing 28 by turning off the alarm eu, for example

209649/0107

2223R62

Switching off the power supply 23. It should be emphasized that in this? All no breaker contact is provided that of accessible outside the housing for actuation by an intruder is.

"The embodiments described are not limited to the ones used Application examples limited. It is also possible, for example, to arrange the detector element at a point which is located elsewhere than in the embodiment according to "Fig. 1 to 3, for example at the top of the door P.

In the 3form version according to Pig. 1 and 2 there is the advantage that the subject matter of the invention can be applied to existing locking devices, only the lock socket needs to be replaced by a housing 1, which contains the trigger mechanism and the detector mechanism contains.

All technical details mentioned in the description and illustrated in the drawings are essential for the invention significant.
