Abstract

The proposal is for an alarm-triggering locking device for the catch and/or hinge side of a door or window to be protected, in the form of a strike plate (23) which can be fitted to a door or window frame by means of screws (27) as the first securing device. A second securing device which is more difficult to overcome by force takes the form of at least one stop component (25) rigidly secured to the strike plate (23) which contacts at least one counter-stop (26) anchored to the door or window frame after a limited movement of the edge plate (23). After the first securing component has been forced, an alarm, especially a silent one, is triggered by radio or via the telephone system. The burglar is then temporarily held by the second securing device, thus allowing the security forces to reach the scene of the break-in and catch the burglar in the course of the crime.

Description

AI arm-releasing locking device for the closing and / or hinge area of a door or window to be secured

Description

The invention relates to an alarm-triggering locking device for the closing and / or hinge area of a door or window to be secured, with a first holding device for the locking device to be overcome by the action of force, with a second holding device for the device to be overcome with greater difficulty the locking device and with means triggering an alarm when the first holding device is overcome, the movement of the locking device in the opening direction of the door or the window being limited after the first holding device has been overcome by the second holding device.

The basic principle of this locking device is known from DE 42 21 585 AI and consists in that, in the event of a break-in under the influence of force, a first hold-up is initially overcome, although an alarm is triggered. This is preferably a silent alarm trigger, in which the opening of an alarm center is reported. After the alarm has been triggered, the burglar is, however, prevented from entering the building by the second holding device, which offers him greater resistance than the first holding device. He now has to make greater efforts to also overcome this second holding device, the time required for this giving the assistants or the police the opportunity to get to the burglary site. The known locking device is designed as an additional securing element, which means an additional material and cost expenditure in the manufacture and assembly. In addition, it is problematic to mount this additional safety device in an optically neutral and non-disturbing manner.

It is an object of the present invention to provide an interlocking device of the type mentioned which triggers an alarm and which is easier to assemble and can easily replace a conventional striking plate on a locking and / or hinge area.

This object is achieved in that the locking device has a striking plate which can be attached to a door or window border by means of retaining screws or bolts designed as a first holding device and that the second holding device is rigid as at least one with the striking plate or the door or window sash is connected-enes or connectable stop element which, after the limited movement of the striking plate in the opening direction, engages with at least one counter-stop element anchored on the door or window frame.

Since the locking device according to the invention is designed as a striking plate, it can be used in a simple manner instead of a known striking plate and is therefore also suitable for retrofitting. The striking plate according to the invention can be easily implemented in the form of known striking plates, in particular in the form of striking plates with an L-shaped cross section in the closing region of a door or a window or of striking plates in the hinge area. When a door or window is broken open, a burglar does not notice that an alarm security system is installed, especially if it is fitted with a silent alarm is provided, that is, when the first holding device is overcome, a radio or telephone alarm is given to a security company manned around the clock. If the burglar encounters the more difficult to overcome second holding device after overcoming the first holding device, he will either give up at the experimental stage or be caught and arrested in the act, since he will time after the alarm is triggered by the second holding device is bound. He can therefore generally be arrested even before he gets into the building. The repressive success caused by this type of protection should have a long-term preventive effect, which should lead to a considerable reduction in damage. Especially in the case of already installed alarm systems with a silent alarm, the additional financial and assembly effort for attaching the striking plates according to the invention is relatively low.

The measures listed in the subclaims allow advantageous developments and improvements of the locking device specified in claim 1.

In a preferred embodiment, the stop element is designed as at least one stop bar arranged at a distance from the striking plate in the opening direction, and the screw heads of the retaining screws penetrating the stop bar are designed as counter-stop elements, the screw heads being spaced apart from the other in the original assembled state of the striking plate ¬ blow bar are arranged. The stop strip is expediently formed in one piece on the striking plate and has an essentially U-shaped cross section. Due to the length of the striking plate and the number of retaining screws or screw heads, the size of the resistance of the second retaining device against Burglary attempts can be chosen practically arbitrarily, without a substantial additional effort being necessary.

In such an embodiment, in an alternative, the retaining screws, which are also designed as the first retaining device, can additionally penetrate at least one shark plate used as a predetermined breaking element, which is held in the original assembly state by means of the retaining screws on the striking plate, the screw heads being broken after the shark plate is broken and a movement of the striking plate in the opening direction through it to the stop bar. The at least one shark plate is expediently designed to be insertable into the striking plate and is prevented from moving towards the stop bar by means of a stop. By selecting the shark plate, the resistance of the first holding device against an attempted break-in can be set here. Furthermore, an alarm wire can be laid in or on this plate in an advantageous manner ^* which breaks when the shark plate is broken and thereby triggers the alarm.

In a second alternative, the screw heads penetrating the stop bar in the original assembly state are arranged essentially flush in openings in the striking plate which have at least the diameter of the screw heads, the screw heads of the retaining screws designed as the first retaining device being in contact with the striking plate or in the manner of Countersunk screws are countersunk. In this embodiment, the striking plate can be designed in a particularly simple and cost-effective manner, that is to say that only the connecting strip with a preferably U-shaped cross section needs to be formed or welded on, and for the rest only different holes need to be drilled.

Another advantageous design of the Locking device consists in that the stop element is designed as a stop strip arranged at a distance from the striking plate in the opening direction and that the counter-stop element encompasses or extends through the terminal strip and is widened at the end of the penetrating area with respect to the width of the penetrating opening, and that Counter-stop element is sunk in a recess of the door or window border. In this embodiment too, only one stop element needs to be molded or welded on the inside of the striking plate, which is later in engagement with the counter-stop element, which is anchored in the recess.

In all versions, the striking plate can expediently be designed as an angled plate, especially if it is an alarm-triggering locking device in the door lock area. It proves to be advantageous if the leg of the striking plate parallel to the opening direction has elongated holes in the opening direction, with retaining screws engaging in these oblong holes and inserted in the door or window frame after the limited movement of the striking plate in the opening direction in Arrive with one end edge of the elongated holes. When the first retaining device is overcome, the friction between the screw heads of these retaining screws and the edge of the elongated holes must also be overcome, and when they rest against an end edge of the elongated holes, these retaining screws make an additional contribution to the mechanical strength of the second holding device. In a simplest embodiment, such elongated holes can also serve exclusively as first and second holding devices.

Finally, an advantageous constructive design consists in the fact that the striking plate is at least partially under one on the door or window border anchored, designed as a counter-stop element, an angle bar is arranged, which has a striking the striking plate after overcoming the retaining screws used as the first retaining device in the opening direction, two stops engaging under the bracket 1 on either side of the recess ¬ elements are arranged on the striking plate. After tearing or tearing out the retaining screws used as the first retaining device, the striking plate can be moved in the opening direction below the angle bar until the stop elements come into contact with the angle bar. As a counter-stop element, this only now provides increased resistance to the further opening movement, namely with its entire holding force. This embodiment essentially requires no milling in the door or window border.

The striking plate is also expediently designed as an angled plate, the leg of this angled plate which does not carry the stop elements having a shape substantially corresponding to the recess in the angled strip and, in the original assembly state, being arranged flush in this recess in order to to achieve stepless outer contour.

In order to prevent the striking plate from bending at greater breaking force so that the stop elements can slide out of the recess, at least one of the stop elements has a toothing that is effective in the stop position with the angle bar to prevent a relative movement between the striking plate and angle bar in the longitudinal direction on.

The alarm-triggering means are advantageously, in a manner known per se, with current and / or voltage-applied tear-off wires or magnetically or mechanically triggerable electrical switches which are triggered when the Give an alarm signal to the striking plate.

The striking plate 10 shown in FIG. 1 as the first exemplary embodiment of a locking device which triggers an alarm is designed as an angled plate with an essentially L-shaped cross section and is in the assembled state in a frame or door (not shown)

Window inserted. An arrow 11 indicates the opening direction of the door or window, not shown. In the leg 12 aligned parallel to the opening direction in the assembled state of the lock hole 10, a bolt entry opening 13 and a latch entry opening 14 are arranged in a manner known per se, in each of which the latch and bolt of a door lock, not shown, engage. In the case of a window, one of the two openings can be omitted. Furthermore, four elongated holes 15 are formed in this leg 12 and run in the opening direction of the arrow 11. On the inside of the second leg 16 of the striking plate 10 arranged at right angles to the first leg 12, two stop strips 17 with an essentially U-shaped cross section are formed or welded on. These two stop bars 17 run essentially in the upper and lower third of the longitudinal extent of the striking plate 10, these stop bars 17 forming groove-like channels with an essentially rectangular cross section in the second leg 16. In the area of the longitudinal edges of these groove-like channels, step-like indentations 18 for receiving correspondingly shaped shark platelets 19 serving as sol 1 fragments are arranged. Four screw holes 20 are formed in each of these holding plates 19, a corresponding hole arrangement being provided on the bottom of the stop bar 17 arranged parallel to the second leg 16, which, however, cannot be seen in the perspective view.

The shark plates 19 serving as sol 1 fragments are designed, for example, as plastic plates, with one of these shark plates 19 having a meandering conductor track 21 to which two Al arm lines 22 are connected. Of course, the lower shark plate 19 can also be provided with such a conductor track 21.

For assembly, the striking plate 10 is inserted and screwed into a correspondingly shaped recess in a door or window border. The retaining plates 19 are inserted into the step-like recesses 18, and then screws are screwed through the screw holes 20 and the corresponding screw holes in the stop bar 17 or the like in the door frame. screwed in. Correspondingly, retaining screws (not shown) are screwed into the elongated holes 15 in such a way that they abut the end of the respective elongated hole 15 which is adjacent to the second leg 16.

In the event of a violent attempt to break open the door or the window, a force is exerted on the striking plate 10 in the direction of the arrow 11. Above a certain force, the shark plates 19 break, and that

Strike plate 10 can move in the opening direction until the heads of the retaining screws now lie against the bottom of the stop bar 17. The remaining retaining screws are now at the opposite end of the elongated holes 15. The length of the elongated holes 15 corresponds to the depth of the stop bar 17. By breaking the holding plate 19, the conductor track 21 is interrupted, and an alarm system, not shown, triggers an alarm signal in a known manner, which can be heard by radio or telephone Watch occupied security company is forwarded.

Now the door or the window is opened by a small gap, but the screws, which are firmly anchored again, now offer increased resistance to a further attempt to break open. The burglar is now time-bound, so that the security company or the police are given the opportunity to get to the burglary site and arrest the burglar, possibly even before he gets into the building.

The Hai tepl ttchen 19 can of course also consist of other material, for example made of sheet metal, whereby other known alarm-triggering means can be used to trigger the alarm, such as magnetic switches or mechanically triggered electrical switches, which move the striking plate 10 in the opening direction ¬ register. A current conductor serving as an alarm wire can 10

be fixed on the frame of the door or window opening or on the striking plate so that it tears when trying to break in or break in. Of course, not only door or window openings, but also other openings can be correspondingly secured with the locking device according to the invention.

2 shows a striking plate 23 of a similar design as a second exemplary embodiment, components or elements having the same or the same effect being provided with the same reference numerals for simplicity and not being described again. A second modified leg 24 without groove-like channels is arranged at right angles on a correspondingly designed first leg 12. A stop bar 25 with a U-shaped cross section, which is designed similarly to the first embodiment, is integrally formed, for example welded, on the rear side thereof. Four holding screws 26 arranged in the upper end area and four in the lower end area, of which only the screw heads are shown, run through the second leg 24 and the stop bar 25 such that the screw heads are flush in corresponding screw holes of the second leg 24 are arranged, which have at least the diameter of the screw heads. The screw holes (not shown) in the stop bar 25, on the other hand, have a smaller diameter so that the screw heads cannot pass through. Furthermore, two holding screws 27 are provided in the central area for fixing the striking plate 23, the screw heads of which are designed, for example, as countersunk heads and hold the second leg 24 on the door or window frame.

In the event of a violent effect on opening the door or window, the retaining screws 27 first tear out, which represent a sol 1 break 1 e or a first holding device. The striking plate 23 can now as in Move the first embodiment by a certain amount in the opening direction until, on the one hand, the heads of the retaining screws 26 rest against the stop bar 25 and the other screws, not shown, come into contact with the end region of the elongated holes 15, as in the first embodiment. When the striking plate is broken off after the retaining screws 27 have been torn out, an alarm signal is in turn triggered by a device known per se. The contact of the heads of the retaining screws 26 on the stop bar 25 and the contact of the screws (not shown) on the opposite end region of the elongated holes 15 now oppose a further attempt to break in, which, like in the first exemplary embodiment, temporarily binds the burglar.

Of course, the number, arrangement and shape of the screws and screw holes are not limited to the illustrated embodiment.

In the third exemplary embodiment shown in FIGS. 3 and 4, a striking plate 28 is again worked out as an angled plate. The first leg 29 of this striking plate 28, which has the locking device opening 13 and the latch entry opening 14, is covered in the assembled state by an angle bar 30 which has a greater length than the closing plate 28 and has a corresponding locking device opening 13 and latches ¬ inlet opening 14 is provided so that these openings are in alignment with each other in the basic state according to FIG. 3. The second leg 31 of the striking plate 28, which is arranged perpendicular to the first leg 29, is flush in the basic state according to FIG. 3 in a corresponding recess of the angle strip 30. The second leg 31 projects beyond the first leg 29 by an amount, which corresponds to the sheet thickness of the angle bar 30 in order to achieve flush and stepless surfaces. In this case, the projecting area 32 can also surround the first leg 29 1 2

overlap a certain amount, the recess in the angle bar 30 being adapted accordingly.

From the free end region of the first leg 29, stop elements 33 which are integrally formed on both sides in the longitudinal direction and are provided with toothed recesses 34 on their side facing the second leg 31. Corresponding toothing elements 35 are arranged on the corresponding inner corner areas of the angle strip 30.

The angle bar 30 is anchored to the frame of a door or window by means of six heavy-duty retaining screws 36. Three further weaker retaining screws 37 serve as sol 1 fractions 1 and run through the angle bar 30 and screw holes 20 of the striking plate 28 arranged below in the frame mentioned.

The original assembly state is shown in FIG. 3. When the door is broken open, for example by prying it open, a force occurs in the direction of arrow 11. Above a certain amount of force, the retaining screws 37 serving as sol 1 break 1 s or shear off. As a result, the striking plate 28 can move relative to the angle bar 30 in the direction of arrow 1 until the stop elements 33 come into contact with the inside corner area of the angle bar 30 and mesh there with the toothing elements 35. For the complete opening of the door, the stronger retaining screws 36 must now be overcome, which binds the burglar in time. The toothing by means of the toothing recesses 34 and the toothing element 36 have the effect that the striking plate 28 cannot be bent out of the corresponding opening of the angle strip 30 by bending the stop elements 33.

In the fourth embodiment shown in FIG. game is a striking plate 40 designed as an angle plate as a cross-sectional view. The first leg 12 corresponds to that of the first and second exemplary embodiments. The corresponding openings, elongated holes and screws are not shown for the sake of simplicity. On the second leg 41 is inside, so in the mounted state on the side of the door frame 42, a stop bar 43 with shaped U-substantially Quer¬ cut formed, is silent SST at spi el SWEi se ^'which is substantially the stop bar 25 of the second Ausfüh¬ example corresponds. Through a longitudinal slot 44 in the wall of the stop bar 43 running parallel to the second leg 41, a transverse web 45 of a retaining bar 46 with a cross-section in the manner of an asymmetrical double-T beam runs. A narrower outer web 47 runs in the stop bar 43, while a wider outer web 48 is anchored to the door frame 42 by means of retaining screws 49. The holding strip 46 is arranged in a groove-like recess 50 in the door frame 42, into which the stop strip 43 also engages when it is in the assembled state. The second leg 41 is anchored to the door frame 42 by means of retaining screws 51 which serve as break points.

5 shows the original assembly state. In the event of a force, the retaining screws 51 serving as sol 1 fraction 1 en tear out, and the striking plate 40 moves in the direction of arrow 11 until the outer web 47 comes into contact with the wall of the terminal strip 43 having the longitudinal slot 44. For the further breaking open the greater force of the stronger holding screws 49 must be overcome, which binds the burglar in time. Furthermore, he must overcome the retaining screws (not shown) which engage through the first leg 12 and which then rest against an end region of the elongated holes 15 (also not shown). In a modification of the fourth exemplary embodiment shown in FIG. 5, instead of the holding strip 46, a plurality of individual holding elements can also occur, which either have a correspondingly shorter length or which are of circular symmetry with the same or similar cross section. To insert the outer webs 47 into the stop bar 43, the latter can have extensions of the longitudinal slot 44 at spaced locations, which enable insertion, after which locking takes place by a longitudinal displacement.

Furthermore, a modification is possible in that the cross bar 45 and the outer bar 47 are fixed on the second leg 41, while the stop bar 43 is fixed on the outer bar 48 and is screwed to the frame 42.

Common to all of the exemplary embodiments is that the holding screws or shark plates serving as sol 1 fragments 1 have to be dimensioned such that they are relatively easy to overcome when attempting to break open, but that they can withstand the stresses of daily use.

The fifth exemplary embodiment of the invention shown in FIG. 6 in conjunction with FIG. 7 is constructed similarly to the third exemplary embodiment shown in FIGS. 3 and 4 and is used primarily for use in doors such as those used in Great Britain or in the United States USA are used. Such doors can be pivoted into the door frame, and the latch or bolt of the door lock engages in the striking plate which is mounted flat on the inner surface of the door frame. Of course, the embodiment shown in FIGS. 6 and 7 can also be used for appropriately constructed windows.

In contrast to the third exemplary embodiment, a striking plate 50 with a flat shape is provided here assembled state is covered by an angle bar 51, which has a greater length than the striking plate 50. The striking plate 50 has a latch entry opening 14, which can also be designed as a locking device opening 13, wherein both openings can also be provided. The first leg 52 of the angle bar 51, which is arranged parallel to the striking plate 50 in the assembled state, has a recess into which the central, protruding region 53 and the latch inlet opening 14 engages in such a way that its outer surface is flush with the outer surface of the first leg 52 runs. At its two end regions, the striking plate 50 has angled stop elements 54 which engage behind second limb elements 55 projecting at a right angle from the first limb 52. These leg elements 55 have recesses 56, behind which the angle-like stop elements 54 are arranged such that their free legs are pushed through these recesses 56 when the striking plate 50 is torn from its anchoring by force.

The sections of the first leg 52 and the second leg elements 55 arranged thereon are connected to one another via a connecting strip 57, which is offset parallel to the first leg 52 in such a way that, in the assembled state, it adjoins the inside of the door is ordered. The first leg 52 is connected to the connecting bar 57 via connecting webs 58.

The striking plate 50 has three screw holes 59, for which purpose screw holes 60 are provided in the connecting bar 57 and the first leg 52, of which only one screw hole 60 is arranged in a central region of the connecting bar 57 on a continuation thereof in the perspective view.

For assembly, the striking plate 50 is pushed into or under the angle bar 51 so that the screw holes 59 with the corresponding screw holes 60 and the protruding central region 53 of the striking plate 50 is arranged in the corresponding recess of the first leg 52 of the angle bar 51. In this state, the arrangement consisting of striking plate 50 and angle bar 51 is screwed to the inner surface of the door surround or to a corresponding recess thereof by means of retaining screws 61. In Fig. 7 only the heads of two retaining screws 61 are shown, which pass through the two outer screw holes 59 of the striking plate 50 in the assembled state. Otherwise, the angle bar 51 is screwed to the door border by further, not shown, stronger retaining screws 61. These stronger retaining screws are located, for example, on the two outer areas of the angle bar 51, which are arranged as a result of the part 1 shown in FIG. 7 in the cut-off area.

If the door (or the window) is opened by force, for example pried open, the retaining screws 61 break or tear, and the striking plate 50 is displaced perpendicular to its longitudinal direction in such a way that the angularly similar stop elements 54 pass through the recesses 56 are pushed through until the angle stop is reached. At break of the retaining screw 61 and during displacement of the ski i eßbl ECHS ^'50 in the manner already described in alarm means are triggered. If the striking plate 50 reaches its stop position on the second leg elements 55, the stronger retaining screws on the angle bar 51 must now be overcome, which temporarily binds the burglar.

In a modification of the illustrated and described exemplary embodiments, a stop element connected to the door or window sash can also act as the second retaining device instead of a stop element rigidly connected to the striking plate. sheet in the opening direction after a limited opening movement comes into contact with a counter-stop element on the door or window border.

In the sixth exemplary embodiment shown in FIG. 8, a strip-like counter-stop element 62 with an approximately L-shaped cross section is embedded in a corresponding recess in the door or window sash 62, a retaining leg 63 arranged on the bottom of the recess being held by means of retaining screws 64 is fixed to the door or window sash 42. A counter-stop leg 65 projecting perpendicularly therefrom points towards the door or window sash 66. A striking plate 67 having three legs is fastened with its central, parallel to the holding leg 63 of the counter-stop element 62, the leg 69 is fastened to the counter-stop leg 65 by means of retaining screws 68. A stop leg 70 extends from one end of the middle leg 69 to the holding leg 63 and lies there, while a locking leg 71 extends from the opposite end of the middle leg 69 to the door or window sash 66. There is a space 72 between the stop leg 70 and the counter stop leg 65. A projection 73 on the stop leg 70 extends towards the counter stop leg 65, which has a corresponding recess 74 at its opposite location. A plastic plate 75 is fixed by means of a screw 76 (e can also be several screws) on the counter-stop leg 65 such that the recess 74 is covered. For simplicity, this plastic plate 75 carries alarm wires, not shown, whose tearing leads to the triggering of the alarm.

In the door or window sash 66, a latch 77 for the closing plate 77 is displaceably guided and is spring-loaded s on the striking plate 67 that it is an opening movement of the

Door or window sash 66 prevented in the opening direction 11 by contact with the locking leg 71. To open the door or window wing 66, the latch 7 is pulled back by an operating handle or an electromagnetic operating device, not shown, so that it disengages from the locking leg 71 and the door or window wing 66 can be opened. In the case of a door, a bolt can additionally or alternatively be provided in a manner known per se. Instead of the locking leg 71 can also occur a locking recess into which the latch 77 or the bolt engages.

If, in the locked state shown, the door or window sash 66 is moved violently, for example by prying it open, in the opening direction 11, the retaining screws 64 first break and the striking plate 67 moves in the opening direction 11 until the stop leg 70 of the striking plate 67 comes into contact with the counter-stop leg 65 of the counter-stop element 62. The projection 73 engages in the recess 74, and the plastic plate 75 breaks and triggers the alarm. To open the door or window sash 66 further, the substantially higher mechanical resistance must now be overcome by the stronger anchoring of the counter-stop element 62, which temporally binds the perpetrator in the manner already described.

In the seventh exemplary embodiment shown in FIG. 9, identical or equivalent components are provided with the same reference symbols and are not described again. A counter-stop element 78 modified in relation to FIG. 8 is pivotally attached via a swivel joint 79 to a holding part 80 which is let into the door or window border 42 and is fixed there in a manner not shown, for example by means of retaining screws. The swivel joint 79 is located in the opening direction 11 at the outermost connection point between the opposite stop element 78 and the holding part 80. At the end region of the holding leg 63 of the counter-stop element 78 remote from the swivel joint 79, a projection 8 extends into a corresponding recess in the holding part 80. This projection 81 has a locking recess 82 into which a locking bolt 83 of an electromagnetic locking device 84 can engage.

In principle, instead of the electromagnetic locking device 8, a mechanically locking device which can be actuated from the inside can also take place, or another known mechanical or electromagnetic locking device can also be provided to prevent a pivoting movement of the counter-stop element 78.

In the unlocked state of the locking device 84, when the door or window sash 66 is opened, the locking plate 67 connected to the counter-stop element 78 pivots, so that the latch 77 can pass the locking leg 71 after a certain pivoting movement. When the door or window wing 66 is closed (this also applies to the embodiment according to FIG. 8), the latch 77 can overcome the locking leg 71 pivoted back into its original position as a result of its rear bevel and can return to the original position.

In the locked position of the electromagnetic locking device 84, the locking bolt 83 engages in the locking recess 82 of the projection 81, so that the counter-stop element 78 is firmly fixed on the holding part 80 and thus on the door or window border 42. In this state, if the door or window sash 66 is opened violently, the retaining screws 64 are broken and the alarm is triggered as in the exemplary embodiment shown in FIG. 8. In the seventh embodiment shown in FIG. 9, the trap 6 is required in contrast to the sixth embodiment, no electrical or manual actuation device.
