Description

introduction

The invention relates to a security window or security door in burglar-resistant design, with an anchored in an opening of a building frame and a filled, in the frame tiltable at least about a tilt axis mounted sash whose tilting movement in a Kippendstellung by at least one of the sash with the safety frame connected to the frame, and preferably attached to the opposite side of the tilting axis of the sash frame is limited.

State of the art

So far, the relevant standards of burglar resistance in windows or doors always refer to the closed state of the sash mounted rotatably and / or tiltably in the frame. In the closed state engage arranged on the casement locking elements, which are displaced by means of a push rod, which in turn is actuated by means of a one-handed rotary handle, in adapted configured locking elements which are fixedly arranged on the frame. By a correspondingly large number of locking elements, i. an arrangement thereof with short distances to each other on all four wing frame legs (typically two vertical and two horizontal), in conjunction with a pronounced positive connection between the locking elements, e.g. patrizenförmig and are designed in a matrix shape and are positively engaged with each other, achieved a relatively high level of security against attempts or Aufbruch attempts.

Insufficient is in such security windows but the burglar resistance in a tilted state of the sash, in this state, the locking elements are not effective because they are not engaged, but by the tilt position corresponding position of the push rod relative to each other and are disengaged. In this case, the connection of the sash to the frame in the region of the tilting axis usually only by standard turn-tilt ribbons in the region of the vertical axis of rotation of a turn-tilt window or burglar-resistant security windows. a bearing cup formed on the opposite side of the sash. Such fittings, as they are used in standard windows that do not meet safety requirements, hold more violent and sustainable attacks on the security window in the tilted state not stand.

In this context, however, it is considered increasingly unsatisfactory when a security window has sufficient security features only in the closed position. Rather, it is also desirable to be able to leave a security window for reasons of adequate ventilation permanently in the tilted state, without this the burglar-resistant effect is lost entirely or in large part. This comes to the problem that it is undesirable or very often difficult to always check whether all windows are located in the safety aspects alone satisfactory closing position of the sash.

From the EP-A-1 516 996 is an explosion-resistant trained window known that should have its blast-resistant properties in particular in the Kippendstellung. For this purpose, the known window on the opposite side of the tilting axis of the sash is provided with a safety scissors made of stainless steel, which is firmly anchored on the one hand in the frame profile and on the other hand engages in the region of the push rod coupled and displaceable end of the scissors in a bearing element, which with a retaining member engages in a profile chamber of the casement, thereby tearing out the safety shear is prevented even under high tensile load.

In terms of burglar resistance, this window, which is designed to prevent explosions, is unsatisfactory, since in the area of the tilting axis wing-frame-side and frame-side locking elements are positively engaged with each other and prevent the squeezing in of the tilting axis. Further, since the lower end of the casement profile engages under the bezel side firmly mounted locking elements, a lifting of the wing or the sash is under the action of a pressure wave or prevented even in a break-in attempt. Unsatisfactory, however, is the security against a displacement of the sash in the horizontal direction parallel to the tilting axis, since neither the embracing of the sash profile to the frame-side locking elements nor the positive engagement of the frame side and wing frame side Verriegelungselömente this movement can resist.

task

The invention has for its object to propose a security window or a security door in burglar-resistant design, which prevents a security against displacement of the sash in the horizontal direction parallel to the tilting axis even in the tilted position of the sash.

solution

Starting from a security window or a security door of the type described above, this object is achieved by at least one fixedly connected to the frame locking element which engages at least in the Kippendstellung with an engagement area such a form fit into a recess in the sash that one to the tilt axis parallel movement of the sash is prevented relative to the frame in at least one direction.

The positive engagement of the engagement region of a frame-fixed locking element according to the invention in a recess in the sash prevents at least in one direction a horizontal displacement of the sash relative to the frame and thus significantly increases security against burglary or breach of the known security window. The safety window or the safety door according to the invention thus makes it possible, if desired, to leave the casement constantly in the tilted end position, without thereby significantly reducing the safety properties with respect to the closed position of the casement. In the windows or doors from the prior art, no adequate protection against break-in or break-in is present in the tilt end position. In the solution according to the invention, it is particularly advantageous that the locking elements which effect the fixing of the casement are arranged fixed to the frame frame, ie, they do not have to be actuated by means of the push rod. Despite the positive engagement in a recess in the sash, while maintaining this positive engagement both a transfer of the sash in the closed position is possible, as well as a transfer of the sash in an open rotational position, if it is at the window to a turn-tilt window is, of course, in the open position no intervention is given.

If there are at least two locking elements integral with the frame, at least one of which prevents movement of the sash in one direction parallel to the tilting axis and at least one other prevents movement of the sash in the opposite direction parallel to the tilting axis, safety will continue increases, since in the horizontal direction parallel to the tilting axis ultimately no movement of the casement is possible.

As an alternative to two glare-frame-fixed locking elements which only act on one side, it is also possible for at least one locking element which is firmly connected to the window frame to prevent movement of the sash frame in both opposite directions parallel to the tilting axis and thus effectively perform a dual function.

Advantageously, at least one locking element is arranged on the tilting axis associated leg of the frame, even if it is in principle possible to arrange a locking element on one of the vertically extending legs of the frame in the vicinity of the tilt axis associated leg of the window frame, as in this area even in the Kippendstellung the distance between the sash and the frame is still very low.

The invention further ausgestaltend it is proposed that the safety window or the safety door has a turn-tilt function and that the locking elements allow a rotational movement of the sash about a pivot axis perpendicular to the axis of rotation. In the comparatively small required depth of engagement makes the rotation of the sash around the vertical axis of a barely noticeable lateral broadening of the recess in the sash required to avoid a collision between the engagement region of the blind-frame fastener and the wing frame side edge of the recess even during the rotational movement.

In the use of existing sash profiles of burglar-resistant security windows, it is particularly easy, the recess in the sash by a cutout in the sash and / or in a Chamber of the same introduced deposit manufacture. The cutout can be adapted very precisely to the geometry of the engagement region of the locking element on the frame.

A particularly intimate connection between the frame and the sash, in the Kippendstellung is achieved when the locking element is a protruding from the inner side of the frame and preferably there screwed bar, which engages in a recess-like recessed groove in the edge region of the sash. The strip may, if necessary, extend almost over the entire length of the lower horizontal Flugfrahmenschenkels and forms with their end faces abutment surfaces for the end sides of the length of the strips adapted groove in the casement. As a basis for this groove can already serve an existing existing groove for insertion on a lower lip seal on the casement. However, such a groove, which is often present in prior art windows, is not sufficient in depth to effect a secure engagement in the tilted position of the sash. For this reason, a deepened recess of this groove to about twice their original depth makes sense.

In order to prevent in particular the possibility of the penetration of lever tools in the lower gap between .Flügelrahmen, profile and frame is proposed that the groove engaging in the groove is a leg of the U-profile and that the other leg covers the lower edge of the sash and so prevents the attachment of lever tools there.

Furthermore, according to the invention it is also provided that the locking element in the tilted position can be brought into engagement with a locking element which is displaceable on the casement by means of a push rod. In this way, not only a security against a parallel to the tilt axis extending horizontal displacement of the sash is given, but also in a direction perpendicular thereto horizontal direction.

In order for the security window or the security door according to the invention also to meet increased aesthetic or architectural requirements, it is provided that the locking element in the closed position and in the Kippendstellung of the sash is arranged invisibly from the interior of a space having the opening of the building.

Finally, there is an advantageous development of the invention is that the fixedly connected to the frame locking element in the Kippendstellung the sash also prevents a vertical movement thereof, preferably up and down. Thus, with a corresponding embodiment of the window according to the invention a very effective fixation of the sash against movements in almost all directions can be achieved.

a view of the wing frame side and the frame-side locking elements of the window according to the figures 5 and 6.

A safety window in anti-burglary design, shown only in partial detail in FIG. 1, has a lower leg 1 of a window frame 2 and a lower leg 3 corresponding thereto in FIG Frame 2 tiltable about a horizontal tilting axis and about a vertical axis of rotation rotatably mounted sash 4. The profile of the leg 1 of the frame has an outer frame profile 5 and an inner frame profile 6, both of which are designed as extruded aluminum profiles and are connected via an insulating web 7 thermally insulated with each other. Similarly, the leg 3 of the sash 2 consists of an outer sash profile 8 and an inner sash profile 9, which in turn is connected via an isoliersteg 10 with the outer sash profile 8. In the casement 4 is a burglar-resistant filling 11, consisting of a multi-pane composite insulating glass introduced, which is fixed therein by means of a arranged on the inside of the window and bolted to the inner casement profile 8 Glashalteleiste 12.

For the purpose of sealing the gap between the casement 4 and the frame 2 is located in the region of the fold of a rubber-elastic material existing center seal 12 a, which is arranged on a lip 13 of the insulating bar 10 of the sash 4.

On the inner window frame profile 6, a locking element 16 in the form of an L-shaped strip is fastened by screwing to the interior of a room 14 associated with the view side 15. The L-shaped bar 16 has a mounting leg 17, to which it is screwed by means of screws 18 with the frame profile 6. The strip 16 further has an engagement region 18 in the form of the leg perpendicular to the attachment leg 17. This leg engages in an adapted groove 19, which is present in the inner casement profile 9. This groove 19 is formed by milling, i. formed by recessing a groove originally present for a rubber lip seal, but without the milling recess for receiving a corresponding sealing profile was used, but did not have the required groove depth for an effective fit.

Figure 1 shows the window in a closed position of the sash 4. The engagement shown in Figure 1 of the engaging portion 18 of the bar 16 is given not only in the closed position of the sash 4 shown, but also in the Kippendstellung, which is not shown in the drawing However, the sash 4 is tilted by about 10 ° inwards. This changes the engagement conditions between the engaging portion 18 of the bar 16 and the groove 19 almost nothing, since the window is pressed in this lower edge region of the inner sash profile 9 to the inner frame profile 6.

The length of the engagement region 18 of the strip 16 corresponds to the length of the groove 19, so that end sides of the engagement portion 18 of the bar 16 can cooperate as abutment surfaces with end walls of the groove 19 and thus a displacement of the sash 4 in a horizontal direction parallel to the tilt axis 20th prevention.

On the opposite side of the window is located between the frame 2 and the sash 4, a safety scissors, which limits the tilting movement of the sash 4 in the frame 2 in a so-called Kippendstellung. Such a safety shear is for example in the EP-A-1 516 996 described. The window according to the invention is thus protected in the area of the safety shear both against displacement to the right and left as well as against impressions or pressures in the room.

In the lower part of the window, the bar 16, on the one hand, causes the casement to not be lifted forcibly upwards. Furthermore, according to the invention, however, the strip 16 prevents the sash frame 4 from being displaced in the horizontal direction parallel to the tilting axis 20 and relative to the frame 2. Overall, thus a high security against burglary is achieved.

The window according to Figure 2 differs from the window shown in Figure 1 only by the different shape of the attached to the inner frame profile 6 strip 16 '. This has in its upper region in cross section in the form of a U. In addition to the bar 16, as shown in Figure 1, shown in Figure 2 bar 16 'has a leg 18', which is below the lower edge 21 of inner casement profile 6 extends and thus covers this edge region 21, ie protects against ingress of a lever tool obliquely from below. Incidentally, the mode of operation of the upper strip, which acts as an engagement region 18 in the groove 19 of the casement profile 6 and prevents lateral horizontal displacement parallel to the tilting axis, is identical to the window according to FIG.

In the case of the window according to FIGS. 3a (closed position) and 3b (tilted position), the engagement area 22 there is from a perpendicular to the plane of the filling of the window projecting nose formed on the frame fixed locking element 23. The bezel-side locking element 23 is positively connected with a matched, with the casement 4 'connected, locking element 24 in the manner of a die / male form fit. This engagement consists both in the closed position of the window shown in Figure 3a, but also in the tilting position shown in Figure 3b, but not in a rotational position, which is why in this position, the two locking elements 23 and 24 by lateral displacement of the locking element 24 by means of the push rod 25th are disengaged, so that the window can be rotated about a vertical axis of rotation in an open position.

While the locking elements 23 and 24 can not prevent a horizontal movement of the sash and frame in a direction parallel to the tilting axis 20, since they are relatively displaceable in this direction because of the possibility of turning the wing in this direction, this displacement safety according to the invention by the engagement of the locking element 23 in the inner sash profile 9 'causes. A positive engagement consists both in the closed and in the tilted state of the sash 4 'between the nose-shaped engagement portion 22 and a matched recess 26 in an inner wall 27 in the inner sash profile 9'. The cutout 26, which is adapted in its length parallel to the tilting axis to the length of the engaging portion 22 (with little play), thus forming the recess according to the invention in the sash 4 'for producing the displacement safety in the direction of the tilting axis 20th

To further increase the safety and strength in the region of the positive connection between the engagement portion 21 and the inner sash profile 3 'is located between the wall 27 of the inner sash profile 9' and the outer wall 28 adapted to the width of this gap insert 29, the example can be made of stainless steel or aluminum. The insert 29 has approximately the same height as the gap, ie abuts the bottom with little play on the wall 30 and the top with little play on the wall 31 of the inner casement profile 9 'at. The insert 29 is inserted before joining the sash 4 'of four legs in the lower horizontal leg 3 and may preferably extend over the entire length of this Fiügelrahmenschenkels 3.

The recess 26 in the wall 27 of the inner sash profile 9 'and the recess 32 in the insert 29 are consistent in their height and width and are - adapted to the dimensions of the engagement portion 22 of the locking element 23 with the necessary clearance.

That in Figures 3a; Incidentally, the inner casement profile 9 'shown in FIGS. 3b and 4a, 4b serves as a starting product for producing the casement profile 9 according to FIGS. 1 and 2. The groove 19 shown there is removed by removal of the web 33 shown in FIGS. 3a, 3b and 4a, 4b and the two opposing small ribs 34 have been recessed or widened in order to obtain a sufficient depth of engagement between the leg of the strips 16, 16 'forming the engagement region 18 and the groove.

With reference to FIGS. 5 to 7, a safety window is described which consists of a sash frame 2 'firmly anchored in an opening of a building and a sash frame 4' provided with a filling 11 'of an Isoller safety glass 'about a horizontal tilting axis 20' tiltable and is rotatably mounted about a vertical axis of rotation, not shown. On the opposite side of the tilt axis of the sash 4 'by means of a non-visible safety scissors with the frame 2' is connected, wherein the safety scissors in a Kippendstellung in which the sash 4 'by a tilt angle of about 10 ° relative to the frame 2' after is pivoted inside, is prevented by the safety scissors at a further deflection, wherein the safety shear is loaded in this case to train.

The frame 2 'consists of an outer frame profile 1', which is coupled via an insulating web 7 'with an inner frame profile 6'. In the same way, the casement 4 'consists of an outer casement profile 8' and thus an insulating web 10 'coupled inner casement profile 3'. The filling 11 'is held by means of a glass retaining strip 12' in the casement 4 '. A between the inner frame profile 6 'and the outer frame profile 1' arranged lip seal 12a 'corresponds to a web 13', which is arranged on the insulating web 10 'of the sash 4'.

An illustrated in Figure 5 frame side fixed to the inner frame profile 6 'connected locking element 30' has a perpendicular to the plane of the drawing of Figure 5 extending cylindrical and chamfered on the free end side pin 31 ', which protrudes from the main body 32' of the locking element 30 '.

In contrast, Figure 6 shows a wing frame side arranged with a push rod 34 'coupled locking element 33', which is displaceable in a direction parallel to the tilting axis 20 'according to the movement of the push rod 34' relative to the sash 4 'within its inner sash profile 3'. The locking element 33 'has a machined bearing bore 35', which is adapted in its diameter to the diameter of the pin 31 'of the locking element 30' on the frame 2 '. The engagement conditions are shown in Figure 3 '. In this position, the locking elements 30 'and 33' to each other, the sash frame 4 'of the window of the closed position shown in Figures 5 and 6 in the drawing not shown tilting transferred, with a pivoting movement about the tilt axis 20' takes place. The lower inner edge "k" of the inner sash profile 3 'abuts it just so on the view side 15' of the inner frame profile 6 '.

Both in FIG. 5 and in FIG. 6, depending on the selected cutting plane, both locking elements 30 'and 33' would be visible. For the sake of clarity, however, in FIG. 5 only the locking element 30 'and in FIG. 2' only the locking element 33 'are shown, whereas in FIG. 3' both are shown.

Furthermore, it can be seen from FIG. 7 that at a distance 36 'between the pins 31' there is another locking element 37 'permanently mounted on the frame side, which is arranged mirror-inverted to the locking element 30', ie. the two pins 31 'face each other. The width 37 "of the locking element coupled to the push rod and displaceable in the horizontal direction parallel to the tilt axis 20 'locking element 33' is slightly smaller than the distance 36 'between the locking elements 30' and 37 ', so that in the rotational position of the push rod 34', in which the locking element 33 'is located exactly between the two locking elements 30' and 37 ', there is no engagement, so that the casement 4' together with the locking element 33 'can be turned on about a vertical axis of rotation.

To increase the security in the closed position of the push rod 34 'is the further frame-side locking element 37', with which the with a continuous Bearing hole provided locking element 33 'also form-fitting manner in the manner of an additional rotary joint can be brought into engagement. However, this position is not shown in FIG. 7 for reasons of clarity.
