The invention relates to a door or a window with at least one frame that can be inserted into a wall opening and at least one sash frame mounted therein, wherein profile areas of the frame on the outside overlap profile areas of the sash frame and profile areas of the frame on the inside are covered by profile areas of the sash frame and wherein external profiles of both the frame and the sash frame are each connected to internal profiles of the frame or the sash frame via insulating elements.

Such a door or window construction is known from DE 44 23 944 A1 and is used primarily in prison cells. For this reason, the known construction has cladding profiles on the inside of the legs of the sash frame and/or the frame and cover these legs - at least partially. The cladding profiles are reinforced in comparison to the other profiles of the window construction and are intended to prevent the window from being forced open from the inside using hand-operated tools (e.g. screwdriver or crowbar).

Furthermore, such prison cell windows and doors are also required to have no fastening options on the inside, for example for any kind of strangulation device, in order to accommodate people at risk of suicide in the cells equipped with them. For this reason, the cladding profiles of the casement frame overlap those of the frame on the inside, as does a sealing profile attached to a glazing bead, which rests against the glass pane with sealing strips. This is intended to protect the rebate area and a stop seal arranged there, and to prevent the sealing profile from being torn out of the glass pane.

The cladding profiles are connected to the casement and the frame using screws, the heads of which are always covered and inaccessible when the casement is closed. This means that unauthorized dismantling of the cladding profiles when the window or door is closed is impossible. In addition, it is in principle possible to retrofit existing window or door constructions with such cladding profiles in order to be able to accommodate people at risk of suicide in the associated cells, for example.

With the known window and door construction, it has been found to be disadvantageous that the connection of the cladding profiles with the rest of the sash or frame cannot withstand all the loads that can be exerted by hand-operated tools. Furthermore, the manufacturing effort for the known construction is comparatively high, which in turn results in relatively high costs.

The invention is based on the object of proposing a window or a door suitable for use in detention cells for the accommodation of persons at risk of suicide, which is characterized by its simple construction and yet can easily withstand the loads exerted by hand-operated tools.

Starting from the door or window of the type described at the beginning, this object is achieved according to the invention in that a profile forming an inner surface of the sash frame is designed as a box profile with a substantially L-shaped cross-section, with one L-leg being directly connected to at least one insulating element and the other L-leg overlapping an inner surface of the frame adjacent to the rebate to such an extent and having such a section modulus about its longitudinal axis that an inner rebate area is inaccessible when manipulated with lever tools.

With the construction according to the invention, the connection of separate cladding profiles with the other cover or sash frame legs can be completely dispensed with. Instead, the entire sash frame structure, which extends inside of the insulating elements, consists of a single box profile, which extends with an L-leg over the inside edge areas of a leg of a cover frame profile and thus protects the rebate area from access.

The door or window according to the invention thus makes the use of a separate cladding profile on the frame side as unnecessary as on the casement side, where the cladding profile and the profile arranged on the inside of the room in conventional window constructions are combined to form a one-piece box profile. Its stable design, which results from correspondingly large wall thicknesses, leads to such a high section modulus around the longitudinal axis of the L-leg covering the rebate area that it cannot be bent away using manually operated lever tools. The rebate area is thus covered in an inaccessible manner even in the event of unauthorized manipulation, so that the construction according to the invention does not provide any fastening options for strangulation devices, such as those formed by cracks or gaps.

In addition, the one-piece design of the box profile gives the sash frame enormous stability, which is also very high in two perpendicular bending planes due to the L-shaped cross section. It is not possible to destroy screw connections between a cladding profile and a base profile connected to it with the design according to the invention. This design therefore meets the requirements for preventing suicides as well as for preventing break-ins in an equally good manner.

According to one embodiment of the invention, the box profile has a wall thickness in the areas facing the interior of the room that is at least 1.5 times the wall thickness in the other areas of the box profile. In this way, the profile can be made lighter overall than if all areas had the same wall thickness. The section modulus around the longitudinal axis of the particularly vulnerable L-leg, which overlaps part of the frame, is particularly large in this way.

If the L-leg overlapping the rebate also has an L-shaped cross-section, a particularly thick sash frame can be achieved, so that the installation of very thick glass panes is also possible. Despite the great thickness of the sash frame, the thickness of the L-leg overlapping the rebate area can be kept relatively low, so that the L-leg facing the frame reliably covers the rebate area even with frame profiles with a standard cross-section. This results in an overall U-shaped cross-section of the box profile, the large extension of which in a direction perpendicular to the pane plane allows not only the use of thick glass panes, but also, for example, the accommodation of fittings and locks.

In a further development of the invention, it is provided that the L-leg overlapping the fold is provided with an edge strip that covers a stop seal in an inaccessible manner. This reliably prevents the stop seal from being torn out, which could be used as a strangulation device, for example.

The connection of the box profile with a separate glazing bead becomes superfluous if the L-leg connected to at least one insulating element is provided on its side facing the glazing with a

formed glazing bead, on which a pane of glass can be supported via a glazing wedge. Compared to separate, subsequently inserted glazing beads, such a one-piece design of the glazing bead with the box profile offers much greater strength. In order to be able to use different glass thicknesses, the glazing bead must be cut to the appropriate length, which when the box profile is manufactured is such that the thinnest of the possible glazings can be supported. Since the one-piece glazing bead necessarily extends into the area of the glazing, the glass pane can only be installed from the outside of the door or window.

If the glass strip and the glazing wedge are covered by a cover strip that extends essentially to the surface of the glazing facing the interior of the room, which is L-shaped in cross section and can be inserted into an adapted groove in the box profile, unauthorized removal of the glazing wedge can also be safely prevented. The cover strip itself is advantageously glued into the groove and therefore cannot be removed by unauthorized persons.

With regard to the task of not encouraging suicide attempts due to the design, it is particularly advantageous if the cover strip, when installed, is flush with the corresponding surface of the box profile.

A further development of the invention consists in that an actuating mechanism for a turning and/or tilting fitting is provided on or in the box profile, which can be actuated by means of an actuating element that can be inserted into an insertion opening in the box profile, wherein the insertion opening can be selectively blocked or opened by a locking plate that is slidably mounted in the box profile, and where the locking plate is provided with a rack, the teeth of which point away from the interior of the room and which can be moved by means of a

to a glazing level, flush with the box profile, which is provided with appropriate teeth on the casing side.

Compared to a design as known from the aforementioned DE 44 21 944 A1, the operation of the locking plate is significantly simplified in this way. While in the known design the longitudinal axis of the profile cylinder runs perpendicular to the plane of the disk, this is now rotated by 90°. This allows the teeth of a pinion coupled to the profile cylinder to engage directly in a rack on the locking plate, so that any further deflection and drive means can be dispensed with. The costs for closing the insertion opening of the actuating element can thus be reduced considerably." " ~

The possibility of mounting the profile cylinder with its longitudinal axis parallel to the glazing plane is created in particular by the fact that the base profile and the cladding profile in the construction according to the invention are combined to form a one-piece box profile which has a correspondingly large installation space perpendicular to the glazing plane.

The invention is explained in more detail below using an embodiment of a cell window, which is shown in the drawing. It shows:

Fig. 2 as Fig. 1, but in the area of a profile cylinder for actuating a locking plate, and

Fig. 3 like Fig. 1, but in the area of a handle gear.

The window 1 shown in Fig. 1 in a partial section consists of a frame 2 that can be inserted into a wall opening and connected to a building part (not shown), a sash frame 3 mounted therein so that it can be rotated and tilted, and a glazing 4 inserted therein and shown broken off.

The frame 2 consists of an outer profile part 5, which is coupled to an inner profile part 7 via two insulating elements 6 designed as insulating webs. The sash frame 3 has an essentially L-shaped box profile 8 on the inside, which is also connected to a solid central profile 10 via two insulating elements 6 and 9 designed as insulating webs. This central profile 10 is positively connected to an outer cover shell profile 11, whereby this connection is additionally fixed using a countersunk screw 12.

A leg 13 of the cover shell profile 11, which is flush with the outer profile part 5 of the frame 2, covers an edge area of the glazing 4 after it has been installed from the outside of the window 1. The glazing 4 is supported on the cover shell profile 11 by a glass seal 14.

On the outside, a hollow leg 15 of the outer profile part 5 of the frame 2 overlaps a recessed leg of the Z-shaped cover shell profile 11 as well as the countersunk screw 12 located therein.

On the inside of the window 1, an L-leg 16 of the box profile 8 overlaps a section of the inner profile part 7 of the frame 5, whereby the L-leg 16 is also L-shaped in cross section. With its free end, the L-leg 16 extends almost to the inward-facing surface

of the inner profile part 7 of the frame 5, whereby a stop seal 17 is inaccessibly covered by a solid edge strip 18 of the L-leg 16.

The box profile 8 has a glass strip 20 formed in one piece with an L-leg 19 facing the glazing 4, which is supported on the inside of the glazing 4 via a glazing wedge 21.

Since the same cover shell profile 11 should always be used for all types of glazing 4, it is necessary to cut the glazing bead 20 to the correct length according to the thickness of the glazing 4.

A cover strip 23 with an angled cross-section is inserted into a groove 22 of the box profile 8 and glued to it. The cover strip 23 extends with an L-shaped leg almost to the inside of the glazing 4 and therefore covers the glazing wedge 21 in an inaccessible manner. Furthermore, this L-shaped leg of the cover strip 23 ends flush with the surface 24 of the box profile 8 facing away from the frame 2.

In order to obtain a particularly large section modulus around its longitudinal axis, the box profile 8 has a wall thickness in the areas facing the interior of the room that is approximately 1.5 times the wall thickness in the other areas of the box profile 8. In this way, bending away of the L-leg 16 is impossible, even when manipulated with lever tools, so that an inner rebate area of the window 1 is inaccessible.

Both the inner profile part 7 of the frame 2 and the box profile 8 of the sash frame 3 are connected to locking elements 25 and 26, which can be brought into positive engagement with one another by displacement in the longitudinal direction of the frame profiles. While the locking elements 25 of the frame 2 are fixed

with its inner profile part 2, the locking element 26 of the sash frame 3 is coupled to a push rod 27 which is slidably mounted in an adapted groove within the L-leg 19 of the box profile 8.

As can be seen from Fig. 3, the push rod 27 is provided with a toothing, which engages with a matched toothing 28, which is located on a pinion 29 of a rotary/tilt gear 30. The rotary/tilt gear is driven by an actuating element (not shown in Fig. 3), which can be inserted with its actuating shaft into a matched opening 31 in the rotary/tilt gear 30 and can thus be coupled with the pinion 29 in a force-locking manner. In the box profile 8 there is an insertion opening 32 for the actuating element, which in Fig. 3 is aligned with a corresponding insertion opening 33 in a closure plate 34. The closure plate 34 is located in a longitudinally movable chamber of the box profile 8 and serves to close the insertion opening 32 in order to prevent any possibility of fastening for strangulation devices when the actuating element is removed.

From Fig. 2 it can be seen that the locking plate 34 is actuated by means of a profile cylinder 35, the longitudinal axis of which extends parallel to the glazing plane. The profile cylinder 35 is approximately flush on the inside with the surface 24 of the box profile 8 and therefore - apart from its harmless insertion opening for a security key - offers no possibility of fastening any means of strangulation.

Inside the box profile 8, the profile cylinder 35 is provided with a pinion, the teeth 36 of which mesh with a corresponding toothing of a rack that is firmly connected to the locking plate 34. By rotating the security key inserted into the profile cylinder, a vertical displacement of the locking plate 34 can be achieved, which in only one position

The actuating opening 32 in the box profile 8 is released and otherwise blocked from the inside of the box profile 8. The profile cylinder 35 is attached to a profile cylinder holder 39 connected to the box profile 8 using a countersunk screw 38.
