Abstract

The invention relates to a device for improving the burglar-proofing and resistance to pelting rain of a window, door or such like. Said device comprises at least one window frame (2), preferably made of frame sections (11), and a sash casement (3) which can be moved from a closed position (34) into at least one ventilation position (17) and presents an eaves element (29). The frame section (11) of the window frame (2) presents an overlay (20) which overlaps the eaves element (29). In the ventilation position (17) a rabbeted gap (18) is formed between the sash casement (3) and the window frame (2) and a water collection chamber (19) is arranged opposite the eaves element (29), in the frame section (11) of the window frame (2). At least one strip (32) which preferably faces said water collection chamber is mounted on the window frame (2) such that it is able to pivot and such that it is substantially parallel to the overlay (20). In the closed position (34) said strip is spring-loaded by a force-accumulating element such that it contacts a side (26) of the frame section (11) while in the ventilation position (17) it largely covers the rabbeted gap (18) so as to prevent any attempt to penetrate further into same.

Description

Device for increasing the security against burglary in a window of a door or the like.

The present invention relates to a device for increasing the security against burglary in a window of a door or the like. At least comprising a window frame and a sash frame that can be transferred from a closed position to at least one ventilation position.

From the German patent specification No. 309 730 a weatherstrip closure has become known, which is also used to seal the frame

Called frame, serves against the casement of a window. The window frame has a vertical lining strip with a eaves edge, which is covered by the weatherboard. The seal consists essentially of a sealing rail, which is located in the space between the lining strip and the weather bar and can turn on a lower edge of the frame in a cramp as a hinge. The seal preferably enters with a nose into a groove in the weatherboard, pressing against the front vertical wall of the groove and being supported on the cramp. The seal can be actuated by a fitting of the rod lock associated with the window in the form of a rod bolt via a toggle lever movably attached to the sash frame.

The disadvantage is that the known seal does not represent any resistance to attempts at break-in and, if necessary, the locking of the rod lock can even be released via the mechanical coupling of the sealing rail and the fitting. A burglar-resistant window, a door or the like has become known from DE-PS 38 41 680, in which a reinforcing plate is arranged on the inside in the frame, which essentially covers the fitting chamber, the reinforcing plate having at least one projection directed into the fitting chamber. If the window gap is manipulated with an intrusion tool, the projection should prevent the intrusion tool from engaging. The strengthening plate is also intended to deflect an penetrating drill from the intended direction.

It is disadvantageous that specially designed profiles are required to accommodate the additional rigid reinforcing plate in the frame, which profiles greatly increase the price of such a window or door.

From DE-PS 42 35 468 is a bullet and burglar-resistant

Framing a window or a door with a casement frame and a window frame have become known, which are provided on their vulnerable side with pairs of a gap-defining, tough attachment profiles made of an aluminum alloy. The gap that forms between the sash frame and the frame is covered by a strip made of stainless steel, which is fastened in a longitudinal groove in one attachment profile and overlaps the other attachment profile.

Here, the bar can be produced from a rectangular as well as from a circular profile.

It is disadvantageous that driving rain can penetrate into the gap due to capillary action and can lead to considerable damage, particularly in winter. Here, too, a separate profile of the frame for receiving the bar is necessary.

From DE-G 88 09 818 is a burglar-proof window with a frame and a sash made of wood or a wood-light metal Combinations of materials have become known in which a metallic angle profile is fastened at least in sections to the frame on the side facing the window frame by screwing or nailing. Here, one leg of the angle profile extends parallel to the pane planes and up to an associated stop surface of the window frame. A seal is arranged on the window frame and bears against the nailed or screwed angle profile in the closed position. The outer frame carries a rain protection rail on the outside, which engages in a step in the area of the eaves edge of the window frame.

It has been found to be disadvantageous that the angular profile in the known window can essentially only be used with wooden frames. In particular, driving rain gets through capillary action between the rain protection rail and the angle profile and thus easily leads to ice damage in winter.

From DE-G 90 04 118 a sealing device for a wing of a window, a door or the like has become known, in which the sealing devices are slidably mounted and guided with a guide rail mounted in a longitudinal channel of an approximately vertical direction on the wing. The sealing strip, which can be sealingly attached to the bottom of a lower frame cross member or a threshold, can be raised or lowered by means of a drive rod which is displaceably guided along the lower wing end and a transmission element connected to it. The transmission link has a control slot with a first slot part running to the sealing plane for the engagement of a control pin. The control pin is located on the sealing strip and the transmission element engages with a lateral shoulder in a guide groove of the guide rails that runs parallel to the direction of displacement of the drive rod. The sealing strip is raised according to the actuation of the drive rod when opening or lowered when closing to prevent the ingress of driving rain. However, it has been shown that the known sealing device requires a high level of production expenditure, and climatic influences, in particular icing, are also able to paralyze the mechanism. After all, this device is only able to withstand an attempted break-in, particularly in the ventilation position.

Another frame profile for window, door and partition elements has become known from DE-G 83 22 347. This frame profile has a supplementary profile made of aluminum, ceramic, stainless steel or a comparable resistant material attached to it. The supplementary profile is arranged with the axis of its greatest section modulus perpendicular to the plane of the window, door or partition wall element and has at least one edge section enlarged in cross section. The edge section is partially overlaid by the supplementary profile of the adjacent frame profile.

A disadvantage is that between the supplementary profiles - similar to DE 42 35 468 - moisture easily penetrates in the ventilation position and can lead to damage in particular in winter, which can seriously impair the function.

The object of the present invention is therefore to provide a device for a window, a door or the like. In which the burglary protection is effectively increased and which can be retrofitted with little effort to all common types of windows or doors and at the same time from the construction of the fitting is largely independent.

This object is achieved on the basis of the preamble of claim 1 in that in the casement at least one pivot-mounted bar is arranged largely parallel to the flap, which in the closed position bears against a wall of the frame profile by means of an energy store. This effectively reduces the effectiveness of intrusion tools and makes intrusion considerably more difficult. At the same time, the swivel-mounted bar also prevents driving rain from penetrating inwards in the night ventilation position. This also ensures a high degree of independence from the design of the fitting. According to the invention, there is no longer any functional linkage of the bar to the fitting in the prior art, and rather the bar automatically follows the wing movement in a pivotally mounted manner according to the invention.

The effect of the device can be further increased in that the width of the bar is larger than the distance between the frame fold and sash fold, the bar extending inclined to the rollover in the closed position. Pressing the bar inwards is prevented, so that the bar cannot be gripped. It can also be provided that the bar is secured against pivoting against the energy accumulator.

According to a further feature of the invention, the swivel-mounted bar is preferably arranged in each case in a groove made in the sash frame, which is arranged in front of a groove that receives a fitting. Almost all common window and / or window types can be quickly and easily provided with such a groove, so that the swivel-mounted bar can be inexpensively retrofitted. The arrangement of the strip for the hardware groove has the effect that an action on the hardware is prevented by means of a tool.

Finally, to further improve driving rain safety, it is also provided that a water collection chamber is arranged opposite the eaves edge in the frame profile of the window frame, which chamber faces the swivel-mounted bar. According to a further feature of the invention, the water collection chamber preferably drops in the direction of the rollover. The water collection chamber is assigned at least one drainage hole penetrating the overturn to the outside for the discharge of driving rain collecting in the water collection chamber. This effectively prevents the formation of water pockets, which in particular avoids the latent risk of damage to the profiles in winter.

According to a further feature of the invention, the frame profile of the frame on the side of the flap facing the water collection chamber has a nose which, when the sash is transferred from the ventilation position to the closed position, engages with the bar in this pivoting operative connection. This makes it easier to bite the bar into the flap.

It is advantageous according to a further feature of the invention that the energy accumulator is formed at least by a spring element. This is preferably accommodated in the groove. This provides a device that is easy to handle in terms of assembly and, in particular, easy to retrofit to increase the security against burglary and driving rain.

In order to prevent deformation of the bar in the event of a break-in, it is provided that the bar consists of a high-strength material. A design made of stainless steel is particularly advantageous, since the favorable corrosion properties can also be used here.

According to a further feature of the invention, the frame profile has the water collection chamber at least along the side of the frame assigned to the floor and the sash frame has the swivel-mounted bar at least along the side of the frame assigned to the floor. This is particularly the seek effectively protected exposed outer area of the frame or casement.

It is advantageous that the overlap is associated with a seal that seals the rebate gap in the closed position and is operatively connected to the casement in the area of the eaves edge. On the one hand, this is easy to retrofit and on the other, it effectively protects the seam gap.

According to a further feature of the invention, the water collection chamber in the frame profile faces the wing frame and surrounds it. Each side of the casement has at least one bar which is in operative connection with the frame profile when the casement is closed. As a result, the window or door can be secured completely surrounding the casement.

The invention is described below with reference to an embodiment shown more or less schematically in the drawing.

Show it:

1 is a perspective view of a casement window with a sash located in the open position relative to the fixed frame,

2 likewise a three-dimensional view representation of a tilt-and-turn window with a sash frame brought into the tilt-open position relative to the fixed frame,

Fig. 3 shows a device according to the invention using the example of the window of Figure 1 with a frame profile

Frame and a sash in a first opening or ventilation position in cross section along the line III-III with a smaller opening angle, and Fig. 4 shows the device according to the invention using the example of the window in the closed position in section.

In the following, the same parts are designated with the same reference numbers.

In Fig. 1 of the drawing is shown in window 1, which has a fixed frame 2 and a sash 3. The sash frame 3 is suspended on the fixed frame 2 by means of hinge fittings 4 about a lateral, vertical axis 5-5, that is to say as a rotating sash. Of course, it is also possible to install the hinge fittings 4 between the sash 3 and the fixed frame 2 of the window 1 in such a way that the sash 3 is moved relative to the fixed frame 2 about a lower, horizontal axis as a tilting sash or about an upper, horizontal axis as a folding sash can.

At least two hinge fittings 4 are arranged between the fixed frame 2 and the casement 3, although only one such hinge fitting 4, namely the upper hinge fitting 4, can be seen in FIG. 1 of the drawing.

Also in Fig. 2 of the drawing, a window 1 is shown, which has a fixed frame 2 and a sash 3. In this case, the sash 3 is optionally mounted so as to be movable about a lateral, vertical axis 5-5 or about a lower, horizontal axis 6-6, that is to say as a tilt-and-turn sash 3, relative to the fixed frame 2.

2, a hinge fitting 4 is provided at least between the upper corner of the casement 3 adjacent to the hinge axis 5-5 and the fixed frame 2, namely that it is connected to a tilt and turn device 7. However, such a hinge fitting 4 can also be provided at the intersection between the two hinge axes 5-5 and 6- 6 adjacent to the sash frame 3 and frame 2, in operative connection with a so-called turn-tilt corner bearing.

A locking fitting 8 is provided on the sash 3, which enables the sash 3 to be fixed relative to the frame 2. For this purpose, latches 9, which are movable by the locking fitting, engage behind latch interlocks 10 fastened to the frame 2 in the closed position.

From Fig. 3 it can be seen that a frame profile 1 1 of the frame 2 is embedded in the bottom 13. The sash frame 3 is assigned to the frame profile 11 in the manner described, in which a partially shown window pane 15 is mounted. The sash frame 3 is transferred into a ventilation position 17 directed into an interior space 16, so that a rebate gap 18 is formed between the frame profile 11 and the sash frame 3. On the side of the frame profile 11 facing the casement 3, a fitting chamber or water collection chamber 19 is arranged which drops in the direction of an upright rollover 20 of the frame profile 11. The upright flap 20 is penetrated by at least one drainage hole 21 through which water collecting in the water collecting chamber 19 is drained into the outer region 22. The flap 20 is closed by a seal 23 and, together with the water collecting chamber 19, has an approximately L-shaped shape, a leg 25 forming the base 24 of the water collecting chamber 19 being inclined and together with a wall 26 of the upright flap 20 facing the casement 3 a knee 27 forms. The drainage hole 21 opens directly above this leg 25 in the knee 27 into the water collection chamber 19. The flap 20 has a nose 28 between the seal 23 and the knee 27.

The sash 3 is shown in the position transferred to the ventilation position 17. The wing frame 3 has an eaves edge 29 and opposite the water collection chamber 19 a groove 30. A swivel joint 31 is accommodated in the groove 30, in which a strip 32 is arranged at the one end in a manner pivoted by a force accumulator in the form of a spring element 33 accommodated in the groove 29 in the direction of the rollover 20. Here, as can be seen in particular from FIG. 3, the strip 32 rests on the casement 3 and directs driving rain reaching the window pane 15 or the casement 3 first in the direction of the folding gap 18 and then in the direction of the water collection chamber 19 and the rollover 20 formed knee 27. Finally, the driving rain emerges from the water collection chamber 19 via the drainage hole 21 into the outer region 22.

The energy accumulator 33 can be embodied both by a mechanically acting spring element, for example a spiral spring, or a hydraulically acting spring element, for example a hydraulic spring. Furthermore, a plurality of grooves 30 can be provided, to which strips 32 are then assigned, as described above. These can also surround the casement 3.

4, the sash 3 is shown in a closed position 34 transferred position. It can be clearly seen that the rollover 20 with the

Seal 23 extends beyond the eaves edge 29 of the sash 3 and the seal 23 bears sealingly on the sash 3. Another seal 35, which is assigned to the casement 3, lies on the interior side on the frame profile 11 of the frame 2 and seals the interior 16 from the water collection chamber 19. During the transfer of the sash 3 from the ventilation position 17 into the closed position 34, the bar 32 comes into contact with the flap 20 (here on the nose 28) and describes a movement directed around the swivel joint 31, the side opposite the swivel joint 31 Ledge 32 slides along the rollover 20 in the direction of the knee 27. The nose 28 can - appropriately dimensioned - support a movement of the bar 32 in the desired direction and facilitate the closing process of the casement 3. In the closed position 34, the strip 32 is supported in the water collection chamber 19, in particular on the bottom 24 of the water collection chamber 19, blocking it.

Any condensate that forms is collected in the water collection chamber 19 and also drained off via the drainage hole 21. Since the drainage hole 21 opens directly into the knee 27, condensate can also escape through the drainage hole 21 below the sash frame 3 and thus the strip 32 adjacent to the flap 20.

Practice has shown that in the event of a collapse, the rebate gap 18 is a weak point in the window or the door. If a burglar with tools gets into the gap 18 - for example by inserting one

Screwdriver in the area of the seal 23 - wedges or pointed tools can be inserted into the fitting chamber or water collection chamber 19 between the frame fold 40 and the sash fold 41 using the lever ratios. The casement 3 is displaced relative to the frame 2 by the wedges so far that the bolts 9 come out of the bolt interventions 10. If special fittings with mushroom head pegs are used, which undercut the corresponding undercuts of the bolt interventions 10, prying out can be made more difficult. The fastening screws of the bolt interlocks 10 and / or the locking fitting 8 are broken out of the profiles (FIGS. 3 and 4) which are thin-walled, in particular in the case of plastic windows, with continued levering.

As can be seen from FIG. 4, the strip 32 closes the space 39 to the outside, so that the insertion of a tool is made more difficult. Due to its size and arrangement, the strip 32 cannot be brought outside into the outer region 22. The width of the bar 32 is namely larger than the distance between the frame fold 40 and sash 41, the Bar 32 in the closed position 34 is inclined to the rollover 20. Pressing the bar 32 into the space 39 is therefore not possible or can only be carried out by deforming the bar 32. Additionally or alternatively, it can also be provided that the bar 32 is secured against pivoting against the energy accumulator 33. The swivel-mounted bar 32 is upstream of the fitting groove 44 receiving the locking fitting, so that no tools can be brought into the immediate vicinity of the bolts or bolt interventions.

An embodiment of the strip 32, for example made of stainless steel, on the one hand brings about a particularly stable variant, but can also bring advantages due to the excellent corrosion properties.

Finally, it should also be pointed out that the strip 32 can of course also be provided on the upright and the upper horizontal profile bars of the casement 3. The possible relative displacements of the casement 3 to the frame 2 are also limited via the strips 32. The strips 32 wedge with circumferential assembly and stiffening the casement 3 relative to the frame 2 due to the inclined position. If necessary, the effect of the bar can be increased by attaching a special reinforcing profile to the knee 27, which cooperates with the bar 32. This also prevents the bar 32 from reaching under, for example by the rollover 20. The strip 32 preferably extends over the entire width of the casement 3, but may also be provided only in the area of the particularly endangered lower corner areas, although the advantages in the event of driving rain largely disappear.
