The invention relates to a window or a door in an anti-burglary or anti-exploitation design with a frame that can be anchored to a building part and a sash frame movably mounted therein as well as at least one grille bar blocking the opening cross-section of the window or door.

Such windows or doors are well known and are always used where ventilation of a room is required as well as protection against people staying in a room leaving it through the window or door or against unauthorized persons entering the room through the window or door. The bars are arranged in such a way that the space remaining between the bars and an adjacent building part and between adjacent bars themselves makes it impossible for a person to get through.

There are several alternatives for attaching the bars: The bars are often embedded in the masonry of a reveal, which is particularly problematic when installing such a window or door at a later date, as this requires breaking open the existing building structure and subsequently closing off openings, and it is often difficult to restore the original condition without visible traces of installation.

Alternatively, it is also state of the art to combine the lattice bars and the associated frame legs into a finished, pre-assembled component and to attach this to the reveal of a window or to the facade in front of it using anchors. It is also possible to attach such a lattice frame directly to the window frame.

On the one hand, these methods are comparatively complex and expensive and, on the other hand, the lattice frames usually have a detrimental effect on the aesthetics of a facade.

The invention is based on the object of proposing a window or a door in which a lattice bar or several of them can be mounted in a simple and cost-effective manner, whereby a facade with such windows or doors should also meet high aesthetic demands.

Starting from a window or a door of the type described above, this object is achieved according to the invention in that at least one lattice bar is held in a form-fitting manner with both end sections in receptacles in opposite legs of the frame.

The invention thus uses the existing frame for the grille bar holder, whereby the assembly is made considerably easier by the fact that the grille bars are inserted with their end sections into the adapted receptacles in the legs of the frame when the frame is assembled, which automatically creates a positive connection. The positive connection cannot be removed again when the window or door is installed by removing opposite frame legs from each other, as these usually lie directly against a reveal. The assembly process is also simplified because the window and grille are not installed separately one after the other, but in a single operation.

One embodiment of the invention consists in that opposite legs of the frame each have a groove opening towards the interior of the frame, into which edge strips of a filling provided with openings engage.

In this way, in addition to the filling of the sash frame, a frame filling can be attached in parallel in a very simple manner, which ensures, for example, that even when the sash frame is open, reaching through the window and throwing objects in or out through the window

is prevented. Nevertheless, ventilation of the room is ensured due to the openings in the frame filling.

In further developing the invention, it is proposed that the casement frame be openable to the outside. Instead of a tilting function of the window with a pivot axis at the bottom, a so-called folding function is preferable in this case, with the pivot axis at the top and the lower side of the casement frame being folded away to the outside.

Furthermore, such a design has the advantage that the frame with its filling prevents direct access to the sash frame from inside the room, which is advantageous, for example, in prison cells or rooms for accommodating persons at risk of suicide.

In this case, a design is preferable in which the receptacles for the grille bar ends are holes that are located on the side of the groove facing away from the interior of the room. The inside view of such a window therefore only shows the filling with openings, which is designed as a perforated sheet, for example, and is therefore not suitable for attaching strangulation devices, unlike the grille bars that are covered by them. The sash frame itself is also not accessible from the interior of the room.

In order to be able to operate the outward-opening casement frames from inside the room in such a construction, an actuating element of an actuating device for the casement is provided to penetrate the filling of the frame in an adapted opening. If the requirements for suicide prevention are very high, the actuating device can be housed in an encapsulated and lockable manner.

A further development of the invention consists in that the sash frame is designed as a skylight and the frame has a rigid filling arranged below the sash frame in a second frame field.

The state of the art also includes windows or doors in an intrusion- or break-out-resistant design with a frame that can be anchored to a part of the building and divided into at least two fields by at least one beam and a sash frame that is movably mounted in at least one field or a rigid filling arranged in this field and at least one filling that closes off a field and is provided with openings.

Such windows are also used, for example, in rooms for the accommodation of mentally ill people. The sash frame filled with safety glass cannot be operated by the occupant because the operating mechanism is locked. In the case of a fixed filling made of safety glass, this is not visible anyway. On the other hand, because the filling has openings, either a constant exchange of air between the room and the environment is possible, or the filling has openings whose size can be individually changed by the occupant using appropriate operating elements.

According to the current state of the art, such fillings are usually screwed onto the surrounding frame legs in the area to be closed from the outside of the room or connected to them with rivets. This type of fastening is time-consuming both in terms of production and maintenance, for example if the filling needs to be cleaned or its adjustment mechanism needs to be repaired.

The invention is therefore also based on the object of proposing a window or a door in which such fillings provided with openings can be connected to the frame legs in a simple and cost-effective manner.

Dietrich-Bonhoeffer-Straße 1-3,35037 Marburg Representative: Patent Attorneys Bauer & Bauer, Am Keilbusch 4,52080 Aachen

According to the invention, this object is achieved - starting from a window or a door of the type described above - in that opposite legs of the field of the frame, which limit the field to be closed with the filling, each have a groove opening towards the inside of this field, into which the edge strips of the filling engage.

This type of connection is characterized by the fact that the filling engages in the respective legs in a form-fitting manner, which is very easy to achieve when assembling the frame, and by the absence of any separate fastening elements, which are particularly problematic from an optical and safety perspective when they are accessible from the inside of the room. The window according to the invention can therefore be assembled easily and in a short time, so that production is cost-effective. In addition, the strength of such a tongue-and-groove connection is very high.

Advantageously, the filling is held all the way round with edge strips in grooves in the legs of the frame, whereby in this case there is a form fit all the way round between the filling and the frame, so that the strength and security against forcible removal of the filling is further increased.

In order to enable the occupant of a room to individually adjust the ventilation rates, it is proposed that the filling comprises two sheets arranged parallel one behind the other, which can be displaced relative to one another in such a way that openings in both sheets at least partially overlap or webs of one sheet cover openings in the other sheet.

If the filling has permanently open openings, such as a perforated sheet, it is sensible to be able to close this field with the help of a movably mounted sash frame.

Advantageously, the sash frame is visible from the outside in order to prevent access from the inside of the room.

Either the filling with openings is made so solid that it meets the requirements for security against entry and escape. Alternatively, it is also possible to make the filling smaller and, under certain circumstances, to block large field cross-sections with at least one lattice bar, which is held as a frame with end sections in holders in opposite legs. This uses the same principle of form-fitting with the frame legs, which is easy to install and cannot be removed after the window or door has been installed, and ensures that the lattice bars are held securely.

The invention is explained in more detail below using two exemplary embodiments of windows, which are shown in the drawing. It shows:

Fig. 8 as Fig. 7, but in interior view, and

Fig. 9 is a vertical section through the window according to Figs. 7 and 8.

A window 1 shown in Fig. 1 and 2 in external and internal views consists of a frame 2, which on the one hand accommodates a sash frame 3 designed as a skylight and which can be folded outwards and on the other hand a lower rigid filling 4. Four frame legs 2a, 2b, 2c and 2d abut one another with mitred ends in order to form an upper field of the frame 2, into which the sash frame 3 formed from four legs 3a, 3b, 3c and 3d, which are also mitred, is inserted so that it can be folded outwards.

A lower field of the frame 2 is formed - in addition to the leg 2c - by three legs 2e, 2f and 2g, in which the rigid filling is inserted.

In the external view, three horizontally and equidistantly arranged lattice bars 5 are visible through the glass filling of the sash frame 3, which are embedded with end sections 6 on both sides in vertically aligned legs 2b and 2d of the frame 2. These lattice bars 5 are located between the sash frame 3 and a filling 7 of the frame 2, visible in Fig. 2.

From Fig. 3 it can be seen that the lattice bars 5 engage with their end regions 6 in the legs 2b and 2d of the frame 2. Profiles 8 of the frame legs facing the interior of the room have a groove 9 with a rectangular cross-section facing the interior of the frame 2, into which edge strips 11 of the filling 7 engage with the aid of a circumferential rubber seal 10. The circumferential positive connection between the profiles 8 of the frame 2 and the filling 7 is created in the same way as the positive connection between the lattice bars 5 and the same profiles 8 of the frame 2 when the four legs 2a to 2d are assembled.

The lattice bars 5 are inserted into the frame legs in plastic bushings 12 made of an elastic material in order to prevent rattling of the lattice bars 5 when the sash frame 3 is operated and to prevent contact corrosion between the lattice bars 5, which are made of high-carbon steel for example, and the profiles 8 of the frame 2, which are made of extruded aluminum profiles.

The sash frame 3 inserted into the upper part of the frame 2 is provided with a filling 13 in the form of an insulating glass pane. More complex glazing in terms of safety technology and a concealed arrangement of the glass holding profiles 14 are not required in this case, since access to the sash frame 3 from the inside of the room is not possible due to the filling 7 in the frame 2. Access to the bars 5, which are arranged between the filling 7 and the sash frame 3, is also not possible from the inside of the room.

In contrast to the profile construction according to Fig. 3, which involves special profiles, the frame 2 of the embodiment shown in Fig. 4 can also be used as an insert frame in conjunction with standard frames 15, as used for conventional security window constructions, in such a way that aligned connections are obtained both on the inside and the outside.

Fig. 5 shows a vertical section through the design according to Figs. 1 to 3, from which the operation of the sash frame 3 can be seen. This is coupled on the inside with a Z-shaped actuating element 16 of an actuating device 17, which is connected to the lower leg 2c of the frame 2 via a bracket 18. The actuating element 16 penetrates the filling 7 of the frame 2, which is mounted in grooves all around, in an opening 19.

Fig. 6 shows the position of the sash frame 3 in an opened position. By operating the actuating device 17, a lever 20, which is connected to the actuating element 16, is displaced in the direction of the filling 7 and penetrates it in the upper section of the opening 19. If, due to special security reasons,

If accessibility of the actuating device 17 is undesirable due to safety requirements, it can be encapsulated by means of a special cover and can only be used by authorized persons after opening the lockable cover.

Fig. 7 to 9 show an alternative embodiment of a window 1', which consists of a frame 2' and a sash 3' mounted therein so that it can rotate and tilt. The frame 2' encloses an upper field with its four legs 2a', 2b', 2c' and 2d', which serves to regulate the ventilation of the room regardless of the position of the sash 3' in the lower field. The lower field is enclosed at the top by the leg 2c' and further by the legs 2e', 2f and 2g'. The four legs 2a' to 2d' are mitred at their ends, while the legs 2e' and 2g' are butt-jointed with the leg 2c' at their upper ends.

Vertically running lattice bars 5' are inserted into holes in the horizontally running legs 2a' and 2c'. The lattice bars 5' are inserted in the same way as the filling T that is positioned in front of these lattice bars 5' on the inside when the four legs 2a' to 2d' are joined together. The inside profiles 8' of these legs 2a' to 2c' are provided with a groove 9 into which an edge strip of a frame 21 of the filling T can be inserted in a form-fitting manner. In order to avoid rattling noises and possible contact corrosion, the frame 21 is mounted in a circumferential rubber seal 10 within the groove 9. The form-fitting end sections 6' of the lattice bars 5' are inserted in plastic bushings 12 in the holes in the frame 2'.

As can be seen from Fig. 7 and 8, the filling T consists of two sheets 22 and 23 which are mounted horizontally in the frame 21 and are provided with horizontally aligned, equidistantly arranged and rectangular openings 24. Depending on the position of the two sheets 22 and 23 relative to each other, the openings 24 in the sheets 22 and 23 arranged one behind the other are congruent, so that a maximum opening cross-section is released.

The openings 24 in the inner sheet 23 can also be closed by the webs between adjacent openings 24 in the rear sheet 23, so that air can pass through. The opening cross-section is adjusted using an adjustment knob 25 arranged on the inside.

The outside of the upper ventilation field of the window 1' is formed by a row of Z-shaped slats 26 arranged horizontally one above the other, which are flush with the outside of the frame 2'. Due to the comparatively narrow width of the openings 24 in the sheets 22 and 23, access to the bars 5' as well as to the slats 26 is prevented.

The sash frame 3' is provided with a filling 27 in the form of an appropriately dimensioned safety glass. The operating device for the sash frame 3' is either concealed so that it is inaccessible to occupants of the room or at least lockable in order to prevent unauthorized opening of the sash frame 3'.

Both windows 1 and T are manufactured in a break-in or break-out resistant design, i.e. using appropriately dimensioned extruded aluminum profiles for the sash and casement frames as well as safety panes, provided that these can be accessed directly from the inside. The use of a cost-effective insulating glass pane is only possible in the case of the skylight of window 1, since the bars 5 in conjunction with the perforated sheet metal filling provide sufficient resistance to break-in or break-out.
