EP3808927B1 - Arrangement with a frame and a wing attached to the frame by means of hinges - Google Patents

Description

The invention relates to an arrangement with a frame having a clear width and a visible side that defines a frame surface, with a frame which engages in the clear width of the frame and is pivotably attached to the frame with the aid of straps about a hinge axis between a closed position and an open position Wing, with a first securing element provided on one of the sash and the frame, and with a second securing element provided on the other of the sash and the frame, the first and second securing elements being formed and positioned such that they When the sash is in the closed position, prevent the sash from separating from the frame, even if the hinges are not functioning.

The term “non-functional” means that the straps are manipulated in such a way that they do not allow the sash to be attached to the frame.

Such an arrangement is from the DE 7723371 U known. In this arrangement, the securing elements are formed by two angle pieces, each of which is screwed to a leg on a surface of the frame or the sash, which lie opposite one another in the closed position of the sash and form a gap between them. The other two legs of the angle pieces protrude into the gap in such a way that their outlines overlap in the gap.

This arrangement prevents the sash from opening in the closed position even when the hinges are removed, as the two legs of the angle pieces protruding into the gap between the frame and the sash get caught. However, it has been shown in practice that the securing of the sash achieved with this known arrangement due to separation from the frame when the hinges are removed can be overcome by applying comparatively small forces, since the screw connections of the angle pieces tear out. This is particularly true if the frame and the sash include hollow profiles to which the angle pieces are screwed using self-tapping screws.

The EP 0 844 348 A1 shows an arrangement in which a locking pin that interacts with a striking plate is screwed into a fastening element. The fastening element is, on the one hand, screwed to the wing and, on the other hand, the hinge tab is screwed to the fastening element.

The DE 89 10 702 U1 shows a band in which a locking part is screwed several times.

From the AT 12 810 U1 An arrangement is known in which the wing and frame profiles each have a reinforcing profile arranged inside the profile, into which fastening screws of the band engage. A securing element is shown, which is also screwed to the reinforcing profile.

The DE 91 14 594 U1 shows a band in which a band tab is arranged in an adjustable manner in a recess in the wing profile by means of a band receiving device. When the hinge flap is adjusted, a locking cam is adjusted at the same time.

The NL 2005595 C2 shows an arrangement in which a band flap is accommodated between walls. A burglar-resistant spike can be mounted on one of the walls.

The EP 0 165 426 A2 shows a band with a security bolt with steps.

From the publication DE 94 13 891 B1 is a band known for doors, windows and the like. This band has a fastening screw which is screwed into a solid threaded piece of a door leaf through an abutment part and a grommet-like extension.

Finally it's out of the DE 87 04 807 U1 a band is known in which a band tab designed as an adjustment part can be adjusted relative to an abutment part attached to the wing by means of a spindle arrangement and can be fixed to the abutment part by means of a fastening screw. To protect against burglary, the adjustment part is additionally connected to the abutment part via a security bolt in such a way that the adjustment part cannot be removed from the abutment part even after the fastening screw has been loosened.

The invention is therefore based on the object of one of the DE 7723371 U to further develop the known arrangement in such a way that it reliably prevents separation of the sash and frame even when the straps are removed, even against higher applied forces.

This task is achieved with an arrangement with the features of claim 1. Preferred developments of this arrangement are the subject of the dependent claims.

In the arrangement according to the invention, at least one of the bands has a band tab with a fastening device which is attached to one of the wings or the frame. The first securing element is attached to both the fastening device and one of the wing and the frame. The first securing element therefore not only has the function of preventing separation of the sash and frame when the sash is in the closed position, but also of improving the fastening device on one of the sash and the frame with regard to the introduction of forces. Due to the development according to the invention, the arrangement is therefore suitable, for example, for heavier wings. On the other hand, it leads Attachment of the first security element both to the fastening device and to one of the wings and the frame means that significantly higher forces have to be applied to destroy the fastening device and the removal of the tape is made more difficult, so that with the arrangement according to the invention there is a significant improvement in burglary security is achieved.

The assembly of the first securing element is carried out in a particularly simple manner since it is screwed to the fastening device using at least one fastening screw.

In the arrangement according to the invention, the fastening device comprises a housing which accommodates a fastening part of the band tab between two mutually parallel walls. The at least one fastening screw extends through at least one of the parallel walls and the fastening part. Due to this arrangement, with the help of the at least one fastening screw, not only the fit of the housing in one of the sashes and the frame can be improved, but also the fit of the fastening part of the hinge tab within the housing, in that the at least one fastening screw, for example, interacts positively with the fastening part and/or the fastening part is clamped between the two mutually parallel walls by elastic deformation of the housing due to clamping forces generated by the at least one fastening screw. According to the invention, the arrangement has an internal thread on one of the parallel walls for a fastening screw. This makes the installation of the at least one fastening screw easier. Preferably, this is the one of the two walls that is removed in the direction of screwing in the at least one fastening screw, since tightening the at least one fastening screw can then cause a clamping fit of the fastening part of the band tab between the two mutually parallel walls.

In a particularly preferred embodiment, one of the wings and the frame comprises at least one contact surface for the first securing element, which is aligned parallel to the frame surface. Since this contact area has a Positive locking of the first security element in the direction of the separation of the sash and frame causes the effectiveness of the first security element against forcible removal and thus the burglary security is improved again due to this measure.

The at least one contact surface is - particularly preferably - formed by a surface of a profile groove of a profile of one of the sashes or the frame, for example by a so-called "Euro groove", which is used for the assembly of components or assemblies, such as fittings, sealing arrangements, locks, striking plates etc. is provided.

The first securing element preferably comprises a first projection extending parallel to the frame surface.

A further development is particularly preferred in which the projection has a step shape in section perpendicular to the hinge axis. Due to this measure, a first securing element is provided which, on the one hand, has a plurality of contact surfaces with which the second securing element can hook when the straps are removed, and on the other hand, the first securing element can be made particularly solid and therefore stable due to the step shape.

The first securing element preferably has contact surfaces that run parallel to the hinge axis.

In one embodiment, the first securing element has contact surfaces that run perpendicular to one another.

In another embodiment, the first securing element has contact surfaces that run like a sawtooth at an acute angle to one another. This means that snagging can be optimized.

The second securing element preferably comprises a second projection extending parallel to the frame surface.

This has - for the same reasons as the projection of the first securing element - a step shape in section perpendicular to the frame surface and the hinge axis, which - furthermore preferably - is designed to be complementary to the step shape of the projection of the first securing element.

The second securing element preferably has contact surfaces that run parallel to the hinge axis.

In one embodiment, the second securing element has contact surfaces that run perpendicular to one another.

the second exemplary embodiment in the assembled state in the direction of the hinge axis.

That in the Figures 1 to 3 Illustrated exemplary embodiment of an arrangement according to the invention (short "arrangement 100") comprises a frame 1, of which only a frame profile 2 extending parallel to a hinge axis S is shown, a wing 3, of which only a wing profile 4 also extending parallel to the hinge axis S is shown, and a band 5, by means of which the wing is attached to the frame 1 so that it can pivot about the hinge axis S between a closed position and an open position. Wing 3 is in the Fig.1 to 3 always shown in its closed position.

The band 5 comprises a first band tab 6 with a fastening device 7, which in the illustrated embodiment is attached to the wing profile 4 of the wing 3. The first band flap 6 forms the in Fig.1 to 3 illustrated embodiment the wing hinge tab.

The band 5 also includes a further band tab 8, which is in accordance with the Fig.1 to 3 illustrated embodiment is designed as a frame band tab and is attached to the frame profile 2 of the frame 1.

The hinge tabs 6, 8 are connected to one another via a hinge bolt 9, which defines the hinge axis S.

A receptacle 10 is provided in the wing profile 4 of the wing 3, into which the fastening device 7 is inserted and with the help of two first fastening screws 12, seen in the direction of the hinge axis S, provided above and below the fastening device 7, passing through the first hinge tab 6 in perforated tabs 11 is attached.

At the in Fig.1 to 3 In the exemplary embodiment shown, a first securing element 13 is provided on the wing side. It engages in a profile groove 14 of the wing profile 4 and rests on two contact surfaces 15, 16, which are aligned parallel to the hinge axis S. The first securing element 13 is screwed to the wing profile 4 with the aid of second fastening screws 17, which are distributed in a direction of the first securing element 13 that extends parallel to the hinge axis S and pass through this in bores. The first securing element 13 comprises a leg 18 which is aligned parallel to the extension of the receptacle 10 into the wing profile 4 and rests on a surface 20 which is formed on a profile projection 19.

There are holes 21 extending from the surface 20 into the receptacle 10, which are aligned with holes 22 in the leg 18.

Furthermore, third fastening screws 23 are provided, which pass through the bores 21, 22 and are screwed into the internal thread 24 of the fastening part 7 are. The first securing element 13 is thus attached both to the fastening device 7 and to the wing profile 4 of the wing 2.

Like in the Fig.1 to 3 can be seen, the first securing element 13 includes a first projection 25, which extends from the wing profile 4 into a gap 26 formed by a clear width of the frame 1 and the wing 3. The first projection 25 has, in a plane perpendicular to the hinge axis S, a stepped cross section with steps 27 which extend further into the gap 26 as the distance from the surface 20 increases. The steps 27 provide contact surfaces that run parallel to the hinge axis S and perpendicular to one another.

The arrangement 100 also includes a second securing element 28, which includes a second projection 29 extending parallel to the hinge axis S. It extends from the frame profile 2 into the gap 26 and also has a cross section with steps 30, which are designed and arranged complementary to the steps 27. The second securing element 28 is screwed to the frame profile 2 using fourth fastening screws 31. Again, the fastening screws 31 are distributed in a direction parallel to the hinge axis S and pass through the second securing element 28 in correspondingly arranged bores 32.

The further hinge tab 8 attached to the frame profile 2 comprises dowel pins 33 which extend perpendicular to a plane E of the frame 1 formed by the visible side L and engage in bores 33a of the frame profile 2. The further hinge tab 8 is fixed in the longitudinal direction of the dowel pins 33 using fastening screws, not shown in the drawing, which are screwed into the frame profile 2.

As in Fig. 2 can be seen, which shows the arrangement 100 in the assembled state, the first and second projections 25,29 of the first and second securing elements 13,28 are at a distance. Since the first and second projections 25, 29 protrude into the gap 26 and have reversely aligned, stepped cross-sections, the wing and frame are separated by at least partial abutment of the steps 27, 28 of the first and second Projections 25, 29 are prevented when the band 5 is removed, for example by removing the band bolt 9 - as in Fig.3 shown - or has been rendered inoperable in another way or, for example, by dismantling at least one hinge flap.

At the in Fig. 4 In the embodiment of the band 5 of the arrangement 100 shown in more detail, the fastening device 7 comprises a housing 34, into which the first band tab 6 with a fastening part 36 formed on a hinge part 35 is inserted in a direction perpendicular to the hinge axis Z, which corresponds to an adjustment direction X. In order to prevent the fastening part 36 from tilting in the housing 34, it comprises guide grooves 37 which cooperate with sliding blocks 38 provided inside the housing 34.

A threaded spindle 39 is provided for relative displacement between the fastening part 36 and the housing 34 in the adjustment direction X. It comprises a first threaded region 40, a second threaded region 41 and an unthreaded region 42 lying between them. The first and second threaded regions 40, 41 have external threads designed in opposite directions. For example, the first thread region 40 has a left-hand thread and the second thread region 41 has a right-hand thread. The fastening part 36 is provided with a first threaded hole 43 into which the first threaded region 40 can be screwed, and the housing 34 is provided with a second threaded hole 44 into which the second threaded region 41 can be screwed. A rotary actuation of the threaded spindle 39 thus causes either both thread areas 40, 41 to be screwed into the corresponding threaded holes 43, 44, which causes the fastening part 36 to be displaced further into the housing 34, or both thread areas 40, 41 to be screwed out of the threaded holes 43, 44 can be unscrewed, which causes the fastening part 36 to be displaced out of the housing 34.

The further hinge tab 8 comprises a fastening part 45 and two hinge parts 46, 47 which are spaced apart from one another in the direction of the hinge axis S and which accommodate the hinge part 35 of the first hinge tab 6 between them. The hinge tabs 6 and 8 are secured with the help of the hinge bolt 9, which is the hinge axis S defined, hinged together by inserting the hinge bolt around the hinge parts 35, 46, 47. To fix it in the direction of the hinge axis S, a stud screw 48 is provided, which can be screwed into a threaded hole in the hinge part 35 (not visible in the drawing) in such a way that its end leading in the screwing direction engages in an annular groove 49 of the hinge bolt 9.

Furthermore, a cover cap 50 that can be placed on the hinge part 35 is provided, the outer contour of which can be placed on the outer contours of the hinge parts 46, 47 to improve the visual impression conveyed by the band 5.

As further in Fig.4 can be seen, the threaded pins of the third fastening screws 23 pass through slot-shaped openings 51 which extend in the adjustment direction X and are screwed into the internal threads 24, which are provided in one of two parallel walls 52, 53. Tightening the third fastening screws 23 results in the walls 52, 53 being moved towards one another by elastic deformation of the housing 34 and thus the fastening part 36 being clamped in the housing 34.

This in Fig. 5 The second exemplary embodiment shown differs from the first exemplary embodiment only in that the steps 27 of the first securing element 13 provide contact surfaces which run parallel to the hinge axis S and in a sawtooth-like manner at an acute angle to one another and the steps of the second securing element are designed and arranged complementary to these steps 27 are.
