Security device for windows and doors with frame and sash

The innovation relates to a security device for windows, doors with a frame and a sash, whereby the side of the frame facing the sash has a frame rebate and possibly a profile groove and the side of the sash facing the frame has a sash rebate and a fitting groove and between the frame and the sash when the window or door is closed, a circumferential chamber is formed between the mutually facing sides of the frame and the sash.

To increase the security of breaking open closed windows or doors in the area of the frame, it is already known to use reinforced fittings as well as additional locking devices in conjunction with the fittings.

The invention is based on the task of making it possible to insert burglary tools between the window frame and the sash frame of

to make it difficult or impossible to enter from the outside through closed windows or doors.

This object is achieved with a security device for windows and doors with cover and sash frames according to the generic term according to the invention in that in the surrounding chamber between the cover frame and sash frame, at least in some areas a web-like security profile strip is firmly attached or molded onto one of the frames, which bridges the distance in the chamber between the two frames and creates a tight seal on the other frame by snapping into a groove of the other frame or striking or overlapping a retaining web of the other frame when the window or door is closed and can be released from the tight seal when the sash frame is opened.

The security profile strip according to the invention is an enclosing profile that is concealed between the frame and the sash in the chamber and forms an additional security lock and sealing closure for doors and windows or locking sashes of any kind. The security profile strip according to the invention can be used for both inward and outward turning sashes or folding sashes of windows and doors, whereby fittings in the form of friction scissors, rotary sliding bearings and also hinges can be used. When hinges are used, however, the pivot point must not be outside the sash frame, but rather above the overlap in order to ensure that the sash can be turned in and out and that the security profile strip can be locked and released when closing or opening.

Advantageous embodiments of the invention can be found in the characterizing features of the subclaims. 35

According to the invention, a one-piece security profile strip can be used for windows and doors in which a profile groove is provided in the frame into which the

The safety profile strip can snap into place when closing and is pulled out again with the sash when opening. The safety profile strip can be concealed and attached or molded onto the sash frame rebate or the frame rebate of the sash frame 5 or frame, and if necessary in a two-part design on both frames. The safety profile strip can be attached along the entire length of a frame beam or parts of it, for example screwed on. It is also possible to attach the safety profile strip not to a rebate of the sash frame but in the fitting groove of the sash frame. When the window or door is closed, the safety profile strip then closes with its free end, i.e. the end opposite the fastening, with the opposite side of the adjacent frame and forms a safety lock and seal. This sealing can be achieved either by snapping into a corresponding groove or, if no such groove is present, by a protruding retaining bar formed either on the frame profile or on a retaining bar strip attached to the frame. In the latter case, one part is formed on the frame and the other part on the sash frame, whereby when the window and door are closed, the chamber formed between the two frames is bridged by the securing profile strip. If an attempt is made to break through between the frame and sash frame from the outside using a burglary tool, the additional securing profile strip, one-part or two-part, offers considerable resistance and thus increased security against the window or door being broken open.

The safety profile strip can either be placed on the surface of the sash frame rebate and possibly in a locking groove on the sash frame rebate and screwed on, for example, or on the surface of the

·

The safety profile strip is used according to the invention along the pivot side of a frame, i.e. along one side of the frame, preferably along its entire length in the area between two fittings. However, it is also possible to provide the safety strip in relation to its longitudinal extension along the pivot side of the frame only in sections or on part of the length of the frame side.

On the side of the sash frame and frame of windows or doors known as the pivot side or hinge side, security against unauthorized opening from the outside is thus significantly increased.

An advantageous design of the security profile strip provides a T-shaped cross-section, whereby the T-beam is used for fastening to the sash frame or frame, for example by means of screws, and the T-web is used to bridge the chamber and create a tight seal by snapping into a groove or striking a web on the opposite frame.

For frame profiles that only have a smooth rebate on the inside, a retaining bar in the form of a retaining strip can be attached, for example by screwing it on. Depending on the size of the retaining bar, the safety profile strip can then also be attached to the opposite side and stop side of the sash frame in such a way that, together with the retaining bar, it forms a bridge, i.e. bridging the chamber space. Such two-part safety profile strips are used in particular for inward and outward turning hinged sashes or folding sashes of windows or doors.

An additional improvement in the security is achieved according to the invention in that the security profile strip has a further approximately transverse, with respect to the web that creates the sealing connection and

This web has a support web branching off from it, which extends towards the outside of the window or door, i.e. approximately parallel to the frame sides of the frame and sash facing the surrounding chamber. Such security profile strips with an additional support web can also be used for outward and inward turning top-hung and side-hung sashes in conjunction with the fittings already listed.

It is also possible to glue or weld the safety profile strip to the casement frame. It is particularly advantageous to form the safety profile strip onto the casement frame profile and/or the outer frame profile, i.e. to form it during the extrusion of these profiles so that they form a unit with the casement frame profile or the outer frame profile.

The invention is explained below with reference to the drawings and exemplary embodiments. 20

The window combination shown in Fig. 1 with a fixed glazed window part 1b and a window sash la that opens outwards or inwards is made from profiles made of, for example, plastic or aluminum, from which a frame 5 and a sash frame 6 are formed. The window sash 1 that can be opened is fixed to the frame by means of friction scissors 2, 3. Fig. 2 shows a schematic view of the window sash la that is open outwards.

In Fig. 3, among many other variants that are possible for window and door combinations, one such example is shown, with an outward-opening window sash la and an outward-opening folding sash Ic, which is also attached to the frame (not shown in detail) by means of friction scissors. All sash parts that can be opened have window handles 3 with latches.

To increase security against windows or doors being forced open when closed by inserting tools into the gap between the frame and

In casement frames, safety profile strips 4 are attached to a particularly vulnerable area of the frame, namely along the so-called turning sides. These safety profile strips 4 are explained in more detail in the following figures. 5

"Fig. 4 shows a schematic cross section AA through the window sash of Fig. 1 opening outwards in the direction of arrow P with the frame profile 5 as an L-profile and the sash frame 6 as a T-profile without a safety profile strip. In the example shown, the sash frames and frame are made of multi-chamber hollow profiles, whereby such hollow profiles can be made of plastic or aluminum. The profiles 5, 6 shown in Fig. 4 are made of rigid PVC by extrusion, for example.

The window frame profile 5 has a wall connection side 50 with correspondingly designed grooves and on the opposite side facing the sash frame a part referred to as the window frame rebate 52 with a profile groove 51 near the outside as well as two rebate webs 52a,b protruding over the rebate 52 and on the outside a stop projection 53 with a groove 54 for receiving a seal not shown here. The sash frame profile 6 has stop projections 63a, 63b on both sides towards the outside, in each of which a groove 64a, 64b is formed for receiving a seal not shown. On the side facing the window frame, the sash frame 6 has the straight part referred to as the sash frame rebate 62 with a flat locking groove 62a and a protruding web 67 and a fitting groove 66 adjoining this for receiving fittings. When the window is closed, a circumferential chamber K is formed between the frame 5 and the sash 6, which is sealed to the outside and inside by the seals (not shown). With less stable profiles or large windows, it is possible and conceivable that a tool can be used to lever in the direction of the arrow S between the frame and the sash in order to open the sash, which is not desired and should be prevented.

To increase the safety of lifting the sash frame, as shown in Fig. 5a, a safety profile strip is arranged in the area of the chamber K, which bridges it from the sash frame to the frame. Sash frame 6 and frame 5 are further reinforced by means of reinforcing profiles 86, 80 inserted into one of the hollow chambers. The sealing profiles drawn into the stops 63a of the frame and sash frame are designated 81, 82. In the embodiment according to Fig. 5a, the safety profile strip has a T-shaped cross-section, with the T-bar 40 resting on the sash frame rebate 62 and being engaged in the locking groove 62a and, for example, being firmly screwed to it by means of screws 9 (not shown in detail). The T-bar 41 now bridges the gap between the frame 5 and the sash 6 and, when the window is closed, snaps into the profile groove 51 of the frame. If an attempt is now made to reach through between the frame and the sash in the direction of arrow S with a tool, the security profile strip 4 forms a resistance that makes it difficult or impossible to break open. This security profile strip 4 is preferably made from a corrosion-resistant material, such as aluminum. However, it is also possible to make the security profile strip 4 from a suitable solid plastic, such as rigid PVC. It is also possible to make the security profile strip 4 in one piece with the sash, i.e. to mold it directly during the extrusion of the sash frame profile, i.e. to form it as an integrated part. This also applies to sash frame profiles made from metal. The glazing and other equipment of the window sash la are also not shown in Fig. 5a. The equipment of a window sash with safety strip 4 shown in Fig. 5a can also be used, for example, for the folding sash Ic according to section BB of Fig. 3.

Fig. 7 now shows how the window sash la is opened or closed by moving the sash frame 6 in

In the direction of arrow P, the safety profile strip 41 is either pulled out of the groove 51 of the frame profile or is snapped back into place when closing. In Fig. 6, the seals 81 and 82 are also shown in the corresponding grooves of the frame and sash. Furthermore, a reinforcing profile 80 or 86 is provided in the frame^5 or sash 6 to increase the stability of the window.

Fig. 5b shows a further security profile strip 4 which offers additional reinforcement and thus further increases the resistance to burglary. The security profile strip 4 according to Fig. 5b is essentially designed with a T-shaped cross-section and is fastened to the T-beam 40 on the sash rebate 62 of the sash 6 by means of screws 9. The protruding T-web 41 serves as a support and sealing web to bridge the gap between the frame and the sash in the chamber and engages here on the frame profile in a profile groove 51 when closed. In addition, a support web 42 is formed on this web 41 of the security profile strip 4 approximately parallel to the rebate 62 of the sash or to the T-beam 40 ₇ , i.e. the support surface of the security profile, at a slight distance therefrom, and is directed towards the outside of the window sash rotating outwards in the direction of the arrow P. This support web 42 is preferably long enough to abut against the inside of the stop projection 63a of the casement frame. The penetration of a burglary tool in the direction of arrow S is significantly increased by this additional support web 42 of the security profile strip 4.

In Fig. 5c, in a modification of Fig. 5a, a two-part 'security profile strip is shown with a security profile strip 4 in T-shape, which in turn is attached to the rebate 62, 62a of the sash frame 6 and the second part in the form of the retaining web strip 7, which is attached in the area of the rebate 52 to the frame 5 between the rebate webs 52a,b and which has a protruding retaining web 70. The

The retaining web strip 7 has an L-shaped cross-section. The overlap of the two webs 41 of the security profile strip 4 and 71 of the retaining web strip 7, which are adjacent to one another when the window is closed, is selected to be large enough to ensure sufficient security against accidental penetration with sufficient mechanical resistance, while at the same time not hindering the easy opening and closing of the window by unscrewing the sash frame 6.

In Fig. 6a, a frame 5 is shown, the frame side of which facing the sash frame forms a flat frame rebate 52 and which has no insertion groove. Here, it is intended to form a protruding retaining web on the rebate 52 of the frame 5 by means of an additional retaining web strip 7. The retaining web strip is preferably molded onto the profile 5, i.e. formed during the extrusion of the profile. It could also be designed as a separate retaining web strip and glued onto the frame, for example. The securing profile strip 4 is provided on the rebate side 62 of the sash frame profile, which is designed as a simple web and is preferably integrated with the profile, i.e. molded onto it. It can also be designed as a separate strip and glued onto the rebate side 62, for example. When the window is closed, the security profile strip 4 strikes the retaining strip 7 and forms a sealing closure and safety lock. It is also possible to design the security profile strip 4 in the embodiment according to Fig. 6a in a T-shape, as shown for example in Fig. 5b or 5c. It is also possible to accommodate the security profile strip 4, in particular with a T-shaped cross-section, in the fitting groove 66 of the casement profile, in which case, according to Fig. 6a, the retaining strip is then attached to the frame rebate 52 of the frame 5 at a position selected further inwards in order to achieve a corresponding retaining closure and sealing closure when the window is closed. The security profile strip 4 and retaining strip 7 are only in the

Area, the turning side of the sash frame and frame provided.

Fig. 6b shows how the sealing between the safety strip 4 and the retaining strip 7 is opened along the pivoting side when the window sash 6 is unfolded.

Fig. 6c shows a further variant of a simple, stable security profile strip 4 consisting only of a web, which is formed on the sash frame in the rebate area 62, is preferably molded on and is inserted with its free end 41 into the profile groove 51 on the frame 5 when the window is closed.

Fig. 6d shows a modification of a safety profile strip with an additional support web 42 according to Fig. 5b. This safety profile strip can also be integrated into the sash frame profile during extrusion.

Preferably, the security profile strip is attached along the most vulnerable side of the window frame, as indicated in Fig. 1 and 3, namely the pivoting side. It can be provided for both inward and outward turning window sashes, whereby the position depends on the respective design and arrangement of fitting grooves, profile grooves and folds on the frame and sash frame in the area of the sides facing each other when the window or door is installed. The security profile strip, which can be made in one or two parts, whereby in the case of a two-part design the counterpart is attached to the other frame, can be manufactured as a single part and then attached to the corresponding frame, or can be molded onto the profile when it is manufactured.
