Description

The present invention relates to an additional window security for increasing the security against burglary of a present on a window window fitting according to the preamble of claim 1.

The term "window" is to be understood here comprehensively. It includes not only windows in the strict sense, such as exterior and interior windows, but also patio doors or the like.

The emphasis in the following is on increasing the security against burglary of tilt-and-turn windows. However, this is not to be understood as limiting. In such windows, a window fitting is present, which regularly has a strike plate and a locking plate associated with the closing mechanism and a coupled with the locking mechanism window handle. In this case, the strike plate in the window frame and the locking mechanism is integrated in the window sash.

Especially with windows of older design, the problem of only low burglary security. Often it only requires the attachment of a crowbar in the fitting-side gap between the window frame and window sash to break the coupling between the strike plate and locking mechanism.

From the DE 10 2005 033 326 A1 an additional closing device for windows is known which is screwed under a window handle of a window and with the window handle on the window sash. The auxiliary closing device is closed with the window handle and can be kept tilted with the locking bar. The lock body consists of two identical halves, which are screwed together and thus allow a left and a right mounting without conversion of the seal.

The well-known additional window security, from which the invention proceeds, can be mounted instead of the existing window handle. Incidentally, the existing window fitting remains unchanged. The additional window lock is equipped with an additional strike plate and an additional lock mechanism associated with the additional strike plate equipped, which are arranged on the window frame or on the window sash. The additional window security has a lockable additional window handle with which both locking mechanisms can be actuated via a continuous actuating shaft. The actuating shaft axis corresponds to the "original" actuating shaft axis of the existing locking mechanism.

With the additional engagement between the additional strike plate and the additional locking mechanism, the burglar resistance of the arrangement can be increased overall.

The well-known additional window security is configurable for right-side mounting and left-side mounting. This is necessary because a window fitting can be arranged depending on the design on opposite sides of the window sash. The terms "right assembly" and "left assembly" have been chosen here only in the sense of a descriptive representation. Of course, this may also be an assembly provided in the upper edge region or in the lower edge region of the window sash.

When changing the mounting configuration, on the one hand change the orientation of the locking plate associated side of the additional window security and on the other hand, the actuation direction. Specifically, in supervision of the left mounting the side associated with the striking plate is oriented to the left, the operating direction is regularly left around. In the case of right-hand assembly, on the other hand, the side assigned to the striking plate is oriented to the right, the actuating direction is to the right.

Basically, therefore, two different variants of the additional window backup are necessary for the realization of the two Montagekonfgurationen. In the known additional window security, this is achieved in that the additional window security is axially symmetrical with respect to their outer dimensions and based on a running through the operating shaft axis transverse axis, so that the additional window attachment can be mounted left and right after a corresponding Umsteckcken the auxiliary window handle. To change the direction of actuation, however, an intervention in the additional locking mechanism is required, which is associated with the installation with considerable effort.

The invention is based on the problem to design the known additional window backup and further develop that a change in the mounting configuration is possible in a simple manner.

The above problem is solved in a window accessory fuse according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Essential is the fundamental consideration that a change in the assembly configuration between the right-hand assembly and the left-hand assembly can simply go back to a turning of an additional closing mechanism designed as an assembly with respect to the auxiliary window securing. Changes within the additional locking mechanism are then no longer necessary.

According to the proposal, the additional locking mechanism is equipped with at least one locking pin, which is adjustable for engagement with the striking plate along a feed axis. Incidentally, the advancing movement of the locking bolt relative to the additional window securing is independent of the assembly configuration, which simplifies the realization of the configuration change by turning the additional locking mechanism.

Of particular importance for the proposed teaching, however, is the fact that the additional locking mechanism is designed as a preassembled subassembly, which in each case has a substantially identical connection to the drive-related coupling on two opposite sides. This drive technology coupling serves primarily to drive the locking bolt.

It has thus been recognized that the equipment of the additional locking mechanism with at least one retractable and retractable locking bolt in combination with the above embodiment of the two-sided connections for propulsion coupling with a suitable design allows a particularly simple configuration change, namely by simply turning the additional locking mechanism ,

It may be pointed out in advance in the sense of a complete representation that the illustrated additional window backup is equipped with plastic covers 1, 2, whose design is best the representations in the Fig. 3 and 4 can be removed. These plastic covers 1, 2 play no role in the proposed solution and will not be considered further below.

The proposed window protection serves to increase the security against burglary of a present on a window, not shown here window fitting. The presently broad understanding of the term "windows" has been pointed out in the introductory part of the description.

The existing and supplemented by the additional window security fitting has a strike plate and a locking plate associated with the closing mechanism and a coupled with the locking mechanism window handle. It is regularly so that the locking mechanism in the window sash 3 and the strike plate is arranged on or in the window frame 4. The window handle is then mounted on the window sash 3 at a location associated with the lock mechanism.

The additional window backup is now mounted instead of the existing window handle and coupled via an actuating shaft 5 with the existing, arranged in the window sash 3 locking mechanism. The additional window security is thus mounted at the point where the original window handle was previously mounted.

The additional window security is equipped with an additional strike plate 6 and with the additional Scbließblech 6 associated additional locking mechanism 7 and with a particular lockable additional window handle 8. Due to the lockability, the additional window handle 8 can preferably be key-operated block in the locked position.

Here and preferably, it is such that both the existing in the window sash 3 closing mechanism and the additional locking mechanism 7 by means of the additional window handle 8 are actuated. Here and preferably, this coupling is realized with a continuous operating shaft 5. By pivoting the additional window handle 8 and the associated pivoting of the actuating shaft 5, the engagement of both locking mechanisms 7 with the associated striking plates 6 can be controlled.

It can be the representations in the Fig. 1 and 2 that the proposed additional window fixing for a right-hand installation ( Fig. 1a ) Fig. 2a )) and a left mounting ( Fig. 1b ) Fig. 2b )) is configurable. How this is done in detail will be explained below.

It is essential first that the additional locking mechanism 7 at least one locking pin 9, here and preferably two locking pin 9 has. The following is primarily of a single locking pin 9 the speech. All statements concerning the locking pin 9 apply equally to an arrangement with several, in particular with two locking bolts.

The locking pin 9 is for engagement with the additional locking plate 6 along a feed axis 10 and retractable. The interaction of the additional locking plate 6 with the locking pin 9 of the additional locking mechanism 7 leaves a synopsis of the Fig. 4 and 7 remove. Specifically, it is such that the locking pin 9 dips into an associated opening 11 in the additional closing plate 6.

The additional strike plate 6 is here and preferably designed as an angle plate with two legs 12, 13, wherein the one leg 12 receiving the openings 11 and the other leg 13 for fixing the additional strike plate 6 on the window frame 4 via screws o. The like. serves.

A synopsis of Fig. 5 and 6 can be seen that the additional locking mechanism 7 is designed as a preassembled module. This means that the additional locking mechanism 7 as such, ie separately from the additional window security, moreover, manageable. This is important for the proposed solution for configuration change, as will be explained.

The synopsis of Fig. 5 and 6 can also be seen that the module on two opposite sides 14, 15 each having a substantially identical terminal 16, 17 for driving technology coupling the additional locking mechanism 7. By "substantially identical" is meant that a coupling on both sides 14, 15 is possible with largely identical transmission elements. For example, a coupling of the additional locking mechanism 7 on both sides with one and the same actuating shaft 5 is possible. All that matters is the geometric parameters that are essential for the coupling. A consistently identical shape is not necessary.

By equipping the additional locking mechanism 7 with the two-sided connections 16, 17, a change of the mounting configuration can be changed simply by turning the additional locking mechanism 7 about a transverse axis 18 running parallel to the feed axis 10 and through the actuating shaft axis 5a. In the illustrated embodiment, the additional locking mechanism 7 is this simply reversed plugged onto the actuating shaft 5. This ensures that one and the same pivoting of the actuating shaft 5 causes a reverse drive direction in the additional locking mechanism 7 when changing the Montagekonfguration. This corresponds to the above required Reversal of the direction of actuation when changing the mounting configuration.

The above transverse axis 18 is as shown preferably in the center plane of the additional locking mechanism 7, which also forms a center plane for the two locking pins 9 simultaneously.

The above configuration change can best be seen in Fig. 2 remove. Starting from the in Fig. 2a ) shown right assembly, the additional Scltließmechanik 7 is dressed such that no longer the side "R", but the side "L" is directed forward. The location of the pages "L" and "R" can be a synopsis of Fig. 5 and 6 remove.

For the completion of the configuration change only the additional window handle 8 is to be coupled in a 180 ° C pivoting position with the actuating shaft 5. The result is the in Fig. 2b ) illustrated assembly configuration.

It has already been pointed out that the additional closing mechanism 7 here and preferably has two parallel locking bolts 9. The two locking pins 9 are synchronous and rectified along the feed axis 10 for engagement with the additional locking plate 6 adjustable. Fig. 2 shows that this type of adjustability is particularly advantageous for the configuration change of the additional window security.

As in the Fig. 5 and 6 shown, the additional locking mechanism 7 is equipped with a module housing 19 having a housing body 19a and a housing cover 19b. The assembly housing 19 is flat overall and accordingly has two opposite flat sides 14, 15. The flat sides 14, 15 need not be exactly flat surfaces. This is only about the flat shape of the module housing 19 in total.

Here and preferably, the module housing 19 on two opposite flat sides 14, 15 each have the connection 16, 17 for the drive-related coupling of the additional locking mechanism 7. Here are the flat sides 14, 15 of the additional locking mechanism 7 substantially perpendicular to the actuating shaft axis 5a aligned.

The connections 16, 17 on the two flat sides 14, 15 are here and preferably formed by a pivotable carrier 20 for the actuating shaft 5. A particularly compact embodiment results from the fact that the driver 20 is designed as a pivotably mounted in particular about the operating shaft axis 5a part with a driving configuration for the actuating shaft 5. The entrainment formation is preferably a square recess, wherein the actuation shaft 5 is then correspondingly a square shaft.

The representation according to Fig. 3 shows that the actuating shaft 5 passes through the driver 20 and even a part of the auxiliary window handle 8.

It can be the representation in Fig. 3 Furthermore, it can be seen that the driver 20 extends substantially over the entire width of the module housing 19 and on both flat sides 14, 15 each provides a connection 16, 17 mentioned above. Thus, the two-sided connections 16, 17 can be realized with only a single component, namely the driver 20, in a particularly cost-effective manner.

In order to accomplish the above-mentioned turning of the additional locking mechanism 7, without having to provide the additional window security incidentally with additional, configuration-specific recordings for the additional locking mechanism 7, it is preferably such that the additional locking mechanism 7 relative to the transverse axis 18th is designed substantially axisymmetric, as far as their outer dimensions are concerned. This can be seen in the illustration Fig. 2 remove well.

In terms of a simple construction of the additional window attachment one and the same narrow side 21 of the additional locking mechanism 7 is assigned to the additional locking plate 6 in both mounting configurations. The locking pin 9 can thus always extend out of the same narrow side 21 of the additional locking mechanism 7. A synopsis of Fig. 5 to 7 shows that the at least one locking pin 9 is arranged on a carriage 22 which is guided along the feed axis 10 in the module housing 19. The carriage 22 is of substantially U-shaped configuration, wherein the driver 20 is located in any case in the retracted position between the two U-legs of the carriage 22. For an interleaving between the driver 20 and the carriage 22 is realized, which in turn leads to a particularly compact design. At the same time a particularly stable arrangement is ensured by the provided over a comparatively long distance engagement between the respective locking pin 9 and the carriage 22 and provided for a comparatively long distance guidance of the carriage 22 in the housing body 19 a.

The illustrated and so far preferred additional locking mechanism 7 also shows a particularly robust realization of the feed for the locking pin 9. The driver 20 is coupled to the carriage 22 via an eccentric 23, whereby the locking pin 9 via a pivoting of the driver 20 on and is extendable.

In detail, the driver 20 is equipped with a feed cam 24 which can be brought into engagement with a feed groove 25 oriented substantially transversely to the feed axis 10 and arranged on the slide 22 for the purpose of feeding feed.

The eccentric 23 of the additional locking mechanism 7 is equipped in a particularly advantageous embodiment with a freewheel, as will become apparent from the following explanations. During the retraction of the at least one locking bolt 9 caused by a pivoting of the driver 20, the feed cam 24 interacts with the feed groove 25 as explained above. This results from a synopsis of Fig. 7a) and 7b ). After reaching the retracted position ( Fig. 7b )) the feed cam 24 leaves the feed groove 25, so that a further adjustment of the driver 20 has no effect on the position of the carriage 22.

It is essential that substantially simultaneously or subsequently to the reaching of the retracted position, a catch 20 additionally provided Blocking eccentric 26 comes into engagement with a blocking groove 27 arranged in the carriage 22, so that in a further adjustment of the driver 20, the carriage 22 is even blocked in the retracted position. This is after reaching the retracted position ( Fig. 7b )) realized in view of the further adjustment of the driver 20 a freewheel with simultaneous determination of the carriage 22 in the retracted position.

In a particularly preferred embodiment, the blocking groove 27 is formed as a circular section, whose radius corresponds to the eccentricity of the blocking eccentric 26 and which is aligned with befindlichem in the retracted position carriage 22 on the Betätigungswellenachse 5a. This ensures in a simple manner that when returning the driver 20 of the feed cam 24 can easily come into engagement with the feed groove 25.

The above freewheel is important if the additional window handle 8 and thus the present in the window sash 3 locking mechanism can be brought by pivoting one behind the other in a locking position, in an open position and in a tilted position. These positions can be here and preferably occupy by 90 ° -weises pivoting the additional window handle 8.

Starting from the example in Fig. 1a ) shown locking position, the additional window handle 8 can be converted by pivoting by 90 ° in the open position. In this case, the feed cam 24 is initially in engagement with the feed groove 25 and causes the retraction of the locking pin 9. Upon further pivoting of the auxiliary window handle 8 of the feed cam 24 as described above disengaged from the feed groove 25, wherein substantially simultaneously the blocking eccentric 26 in Engagement with the blocking groove 27 comes. Here it is clear that the above freewheel is necessary in the transfer of the additional window handle 8 and thus the present in the window sash 3 closing mechanism of the open position in the tilted position. This adjustment may ideally have no effect on the additional locking mechanism 7, since the additional locking mechanism 7 plays no role at least in the illustrated embodiment when located in the tilt position window.

Fig. 3 shows that the additional window security has a housing 28 which receives the additional locking mechanism 7. This housing 28 is designed with respect to the above-mentioned transverse axis 18 substantially axisymmetric, as far as the outer dimensions are concerned. This is also necessary in order to use the additional window security on opposite sides of a window sash 3 after the above configuration change.

In order to further increase the security against burglary, it is preferable that the additional strike plate 6 for the at least one locking pin 9 each have an opening 11 in the form of a bore, which corresponds to the essential game essentially the diameter of the respective locking bolt 9, wherein the at least one locking pin 9 at its front end a circumferential groove, not shown, which supports an additional, the burglary security increasing hooking between the locking pin 9 and the additional locking plate 6.

Another variant for increasing the security against burglary is that the additional locking mechanism 7 is connected to an additional sheet, which is in the closed window in engagement with the additional locking plate 6 and in particular the additional locking plate 6 engages behind. In the illustrated embodiment, the additional sheet is in the installed state with the housing 28 - and thus with the additional locking mechanism 7 - connected and extends with the window closed in the direction of the additional locking plate 6 and on the additional locking plate 6 away to there the Additional strike plate 6 with a curved in the direction of the window paragraph o. The like. To reach behind. This engagement between the additional sheet and the additional strike plate forms in a pivot window during the adjustment of the window in the closed position, without actuation of the additional locking mechanism 7. The additional sheet provides additional security against prying open the gap between the window sash 3 and Window frame 4.

Finally, it is preferably provided that the additional strike plate 6 is designed substantially axially symmetrical with respect to the above-mentioned transverse axis 18, as far as its outer dimensions are concerned. This is also advantageous in the sense of a configuration change of the additional window backup.
