Description

The invention relates to a security window or a security door in burglar-resistant design, with an anchored in an opening of a building frame and a frame provided with a filling and tiltable about a horizontal tilt axis tiltable about a vertical axis of rotation sash frame whose tilting movement in a Kippendstellung by at least a safety scissors connecting the sash to the frame and preferably attached to the opposite side of the tilting axis of the sash is limited and with a first with a concealed in a rebate between the sash and the frame guided push rod of the sash coupled first locking element which in a tilted position of the Push rod with a fixedly connected in the frame second locking element is such a form-fitting engagement that both locking elements about the tilt axis rotatably relative to each other ar and that is in a rotational position of the push rod out of engagement with the fixedly connected to the frame second locking element, so that a rotational movement of the sash around the rotation axis is possible.

State of the art

For example, older-style windows go from the DE 885 211 C out. Therein, windows are described with turn-tilt function, which have on the interior of the facing surfaces of the frame on adjusting means by which a change of fitting position between a rotational and a tilt position is possible.

So far, the relevant standards of burglar resistance in windows or doors always refer to the closed state of the rotatable and / or tiltable mounted in the frame sash. In the closed state engage arranged on the casement locking elements, which are typically moved by means of a push rod, which in turn is actuated by means of a one-handed rotary handle, in suitably designed locking elements that are firmly on Frame are arranged. By a correspondingly large number of locking elements, ie an arrangement thereof with short distances to each other on all four sash limbs (typically two vertical and two horizontal), in conjunction with a pronounced positive connection between the locking elements, which are configured patrizenförmig and female and positively engage with each other, achieved a comparatively high level of security against attempts or Aufbruch attempts.

Inadequate in such security windows but the burglar resistance in the tilted state of the sash. In this state, the locking elements are not effective because they are not in engagement with each other due to the corresponding position of the push rods, but displaced by displacement of the push rod relative to each other and out of engagement. Even with burglar-resistant security windows in this case the connection of the casement to the frame in the tilting axis usually only by standard turn-tilt ribbons in the vertical axis of rotation of a tilt-turn window or a bearing cup on the opposite side of the Formed wing frame, wherein a push rod actuated bearing element engages in the tilted position in the bearing cup. Such fittings, as they are used in standard windows that do not meet safety requirements, hold more violent and sustained attacks on the security window in tilted state not stand.

The DE 94 09 388 U1 For example, discloses a window that should be characterized in the closed position by a large burglar resistance. For this purpose, blind and sash frames of the window are connected in the tilting axis via a "mushroom head connection".

In this context, however, it is increasingly regarded as unsatisfactory when a security window has sufficient security properties only in the closed position. Rather, it is also desirable, a security window for reasons of adequate ventilation permanently tilted Condition to leave, without thereby the burglar-resistant effect is completely or largely lost. Added to this is the problem that it is undesirable or often very difficult to always check whether all the windows are in the safety aspects alone satisfying closed position of the sash.

From the EP 1 516 996 A2 is a blast resistant window is known, the frame and sash are provided in the tilting axis with displacement limiting elements, which - apart from a rotational position of the window - mesh so that a violent displacement of the sash (even in a tilted position) is approximately perpendicular to its plane is prevented.

task

The invention has for its object to propose a security window or security door in burglar-resistant design, which also in the tilted position of the sash a security against both a horizontal movement of the lower end of the sash perpendicular to the tilting axis and a vertical movement of the sash perpendicular to the Tilting axis prevents. In this case, the determination of the sash relative to the frame as low as possible or preferably be completely free of play.

solution

Starting from a security window or a security door of the type described above, this object is achieved in that the coupled with the push rod first locking element engages with an engaging portion in a chamber of the sash profile such positive fit that the locking element only from an open end of a leg of the Sash frame is inserted into the sash profile.

In this way, a very durable positive connection between the engagement region of the locking element and the coupling region thereof is created. This is of particular importance because the push rod with the associated storage groove is usually inadequately firmly connected, so that even if a very strong connection between the locking element and the push rod latter could be torn out of the casement profile, if the engagement area according to the invention would not interlock positively in a chamber of the casement profile, so that in this case the strength of the walls of the sash profile is used.

In the tilted position of the casement, a positive engagement between a blind frame fixed and a displaceable with the push rod locking element is created, which is a kind of additional hinge or rotary joint, wherein the axis of rotation of this additional joint coincides with the tilt axis. The production of this additional positive engagement between sash and frame, which must be disabled in the rotational position of the push rod to allow the rotation of the sash, done in a very convenient manner by operating the push rod, which in turn is typically operated by a one-handed rotary handle. The user thus notices nothing of the production of this additional positive connection, but this happens automatically when switching between the rotational position and the tilted position. The advantage is in addition to the very high level of convenience, incidentally, in the fact that the production of this safety-relevant additional positive connection can not be forgotten, whereby the security properties would be very adversely affected.

A major advantage of the positive engagement in the form of an additional band or swivel joint is that it prevents a relative movement between the sash frame and frame with very little play or almost free of play in all directions perpendicular to the tilt axis. Herein, such an additional rotary joint differs very advantageous from other known from the prior art form-fitting interlocking locking elements, for example in the form of patrizen-matrix-shaped elements or those with grooved and mushroom-head engagement.

According to a particularly preferred embodiment of the window according to the invention or the door according to the invention are both locking elements by an edge strip of the sash from an opening to be closed having space of the building from invisible covered, so that the window or the door according to the invention can also meet increased architectural or aesthetic requirements. This is made possible in particular because the push rod extends in a rebate area of the window and thus is also not visible.

Moreover, it is particularly advantageous if another firmly connected to the frame locking element is provided, with which the push rod coupled to the locking element with a side which is opposite to the first fixed to the frame locking element, in the closed position of the push rod engages. In this way, not only in the tilted position an additional positive connection is achieved, but also in the closed position, wherein the type of positive connection in the closed and tilted positions are preferably identical. Only in the rotational position of the push rod, which is arranged in conventional handle operations between the closed and the tilted position, the push rod-side locking element is free and with none of the two fixed frame fixed locking element engaged.

One way of forming the additional swivel joint between the glare and sash frame is that the locking element coupled to the push rod has at least one pin which engages with a matched bearing bore in a locking element connected firmly to the frame in the tilted position and / or in the closed position the push rod is engageable. Alternatively, it is also possible that the locking element coupled to the locking element has at least one bearing, with which a pin of a fixedly connected to the frame locking element in the tilted position and / or the closed position of the push rod is engageable. In principle, it is even possible that the coupled with the push rod locking element has on one side a pin which with a matched bearing bore in a first, fixedly connected to the frame locking element in the tilted position or in the Closed position of the push rod is engageable and that coupled to the push rod locking member further comprises on the opposite side a bearing bore with which a pin of a second, fixedly connected to the frame locking element in the closed position or in the tilted position of the push rod engageable is.

The invention will be explained in more detail below with reference to three exemplary embodiments of safety windows which are illustrated in the drawing, in which:

FIG. 1

a section through a window frame-wing frame combination with a bezel side firmly mounted locking element,

FIG. 2

as FIG. 1 but with a wing frame-side locking element coupled to the push rod,

FIG. 3

a view of a corner of a security window with two bezel side firmly mounted locking elements and coupled to the push rod wing frame side locking element,

FIG. 4

as FIG. 1 but with a deepened inner sash profile,

FIG. 5

as FIG. 2 , but with a sash profile enlarged in depth.

With reference to the FIGS. 1 to 3 a safety window is described that from a fixedly anchored in an opening of a building frame 2 and a provided with a filling 11 of an insulating safety glass sash 4, in the frame 2 about a horizontal tilting axis 20th 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 is connected by means of a non-visible safety scissors with the frame 2, the safety scissors in a Kippendstellung in which the sash 4 is pivoted by a tilt angle of about 10 ° relative to the frame 2 inward, is prevented by the safety shear on a further deflection, 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 coupled via an insulating web 10 inner casement profile 3. The filling 11 is held by means of a Glashalteleiste 12 in the casement 4. A arranged between the inner frame profile 6 and the outer frame profile 1 center seal 12a corresponds to a web 13 which is arranged on the insulating web 10 of the sash 4.

An in FIG. 1 shown blind frame side fixed to the inner frame profile 6 connected second locking member 30 has a perpendicular to the plane of the FIG. 1 extending cylindrical and chamfered on the free end side pin 31, which protrudes from the main body 32 of the second locking element 30.

In contrast, shows FIG. 2 a wing frame side arranged coupled to a push rod 34 first locking member 33 which is displaceable in a direction parallel to the tilting axis 20 in accordance with the movement of the push rod 34 relative to the wing frame 4 within the inner sash profile 3. The first locking element 33 has a frontally chamfered bearing bore 35, which is adapted in its diameter to the diameter of the pin 31 of the second locking element 30 on the frame 2. The intervention conditions are in FIG. 3 shown. In this position, the locking elements 30 and 33 to each other, the sash 4 of the window of the in the FIGS. 1 and 2 shown closed position in the drawing not shown tilting position transferred, wherein a pivoting movement about the Tilting 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.

As well in FIG. 1 as well as in FIG. 2 Depending on the selected cutting plane, both locking elements 30 and 33 would be visible. For the sake of clarity, however, is in FIG. 1 only the second locking element 30 and in FIG. 2 only the first locking element 33 shown, whereas in FIG. 3 both are shown.

Out FIG. 3 Furthermore, it can be seen that at a distance 36 between the pins 31 there is a third locking frame-side firmly mounted locking element 37, which is arranged in mirror image to the second locking element 30, ie the two pins 31 face each other. The width 37 'of the coupled with the push rod and in the horizontal direction parallel to the tilting axis 20 slidable first 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 first Locking element 33 is located exactly between the two locking elements 30 and 37, there is no engagement, so that the casement 4 can be turned together with the first locking element 33 about a vertical axis of rotation.

To increase the security in the closed position of the push rod 34 is the third frame-side locking element 37, with which the provided with a continuous bearing bore first locking element 33 is also form-fitting manner in the manner of an additional pivot joint engageable. This position is in for clarity FIG. 3 but not shown.

In order to increase the strength of the casement 4, this may consist of solid material in the region of engagement of the frame-frame-fixed locking elements 30, 37 or be provided with a reinforcing insert.

That in the FIGS. 4 and 5 shown window differs from that according to the FIGS. 1 to 3 only in the enlarged in its depth 39 inner Sash frame profile 3 'and a depth adapted thereto glass retaining strip 12'. This depth 39 makes a cutout in the form of a cutout, as in the embodiment according to FIG. 1 is required for the frame side second locking member 30 is unnecessary. The tilting axis 20 and the entire locking element 30 are outside of the inner sash profile 3. However, the inner sash profile 3 also causes in accordance FIG. 4 an engaging behind the underside 40 of the second locking element 30, so that the sash 4 'is additionally secured against vertical movement or a movement parallel to the filling 11 in the tilted state of the sash 3.

As it turned out FIG. 5 results, is also the wing frame side arranged first locking element 33 ', as well as the first locking element 33 according to FIG. 2 , by means of two engagement portions 41 'and 42' with the inner sash profile 3 'positively coupled to increase the resistance to tearing out. In the first locking element 33 according to FIG. 2 these are equivalent engaging portions 41 and 42.

The engagement conditions in the tilted position and in the closed position and the non-existing engagement in the rotational position of the casement are consistent with the illustrations in FIG. 3 match.
