EP3420166B1 - Lift-out protection device for a leaf, which can be moved in a parallel manner, in the form of a sliding and tilting leaf or a sliding leaf - Google Patents

Description

The invention relates to a carriage with an anti-lift device for a parallel sliding wing as a sliding-tilting wing or sliding wing according to the preamble of claim 1.

The wings of parallel sliding or sliding windows or doors often have a relatively high mass, which is abruptly braked when closing from the parallel position in the frame when the wing strikes the fixed frame. Opening a parallel sliding wing as a sliding and tilting wing or sliding wing can cause unintentional jumping, which causes the sliding wing to slide out of the guide rail and thus cause the window or door to crash. Furthermore, the conventional parallel tilt and slide systems or slide systems do not offer secure protection against unauthorized lifting of the sash of the parallel tilt or slide window or the door.

From the DE 2 536 089 A1 is known as an anti-lift device for movable sliding and tilting windows with rollers arranged one behind the other in the direction of displacement of the sash, supported on a running rail and at least one opening arm or opening scissors. A ledge gripped by the lower extension arm ends has at its free end a lateral, strip-shaped extension directed towards the extension arms, which is to form an anti-lift device from a hook-like extension or a cross-sectionally angular cross-section of the lower wing cross member in the sliding position of the wing.

The present anti-lift device can easily be pulled out of the bar due to the large play and the angular shape of the bar, so that the protection is removed. In addition, with this version of the anti-lift device, the sash can only be installed in the frame with considerable effort.

From the DE 3 639 998 A1 has been made known with a fitting for a parallel-adjustable horizontal sliding sash, in particular for a tiltable and parallel-adjustable horizontal sliding sash of windows, doors, with the wing engaging and pivoted on a vertical plane, lower hinged devices, each of which is carried by a carriage on the a running parallel to the plane of the fixed frame running rail is guided laterally.

This known anti-lift device can also be easily pulled out of the horizontal counterpart due to the large play and horizontally formed projection, so that the protection is removed. In addition, the fixed arrangement of the anti-lift device on the hardware of the sash makes it more difficult to mount.

Furthermore, from the EP 2 538 009 A2 a carriage for a wing for longitudinal movement of the wing in a parallel-parked position with an anti-lift device has become known. For this purpose, a housing area has at least two rollers and a bearing point for pivotally mounting an extension arm, an upwardly pointing spring piece being slidably inserted in an end section of the housing area in order to move the carriage after a tilting movement in the inserted state of the carriage relative to an overlapping section of a carriage rail Moving a spring piece and thus reducing a gap below an overlapping section to secure.

If the gap between the carriage and the carriage rail of the area described above is restricted by the spring piece which has the anti-lifting device, stresses can occur in the tilted position in particular, which can cause a restriction during the tilt opening or the tilt opening width. Furthermore, the well-known Improperly deactivate the anti-lift device by hand, either consciously or unconsciously.

Furthermore, the EP 1 688 573 A1 referenced with a sliding window with a window frame, a wing with wing frame profiles which can be opened parallel to the window frame and which can be moved parallel to the window frame in a parallel position. The carriages are secured against lifting out of a running rail by anti-lifting devices. The anti-lift devices are fixed on a rod. The anti-lift device has a through hole and can therefore be pushed onto the rod and fixed to the rod using a clamping screw. A slider is able to grip behind an undercut web of the running rail and thus ensure that the respective carriage cannot accidentally jump out of the running rail. Due to the undercut groove on the running rail, the fittings can be secured with the anti-lift device.

The object of the present invention is therefore to remedy the known shortcomings and, in contrast, with little effort and at low cost, provides an anti-lift device on a parallel sliding or sliding window or door, which is also simple, fast, safe and precise can also be retrofitted and adjusted and professionally dismantled.

This object is achieved by the features of patent claim 1.

The anti-lift device is to be arranged in such a way that it is suitable for a sash that can be moved in parallel as a sliding, tilting sash system or sliding sash system of a window or door. The sash, as a sliding tilt sash system, enables tilting in a closed position from the sash to a frame. Furthermore, the wing can be moved from the closed position into a position parallel to a frame, by means of at least one carriage with at least two rollers and a bearing point for pivoting an extension arm. Furthermore, the wing allows in parallel Position a shift, the carriage is guided in a carriage rail through the anti-lifting device against lifting.

It is also advantageous that the anti-lifting device can be inserted laterally into the carriage rail with play, so that at least one anti-lifting device can be connected to the carriage at one end and guided in the carriage rail with the carriage. The connection is designed so that assembly or disassembly is accessible, but cannot be viewed directly for improper handling, and therefore cannot be solved unintentionally. A safety anchor attached to the anti-lift device forms a stable, form-fitting reduction of a U-shaped rear handle on the carriage rail by means of a support shoulder and secures the wing in the closed position, in the parallel position and in the tilt-open position against lifting.

According to the invention, it is also seen that the anti-lift device in the closed position of the wing relative to the window frame, in the parallel displaceable position and in the tilted position of the window wing towards the window or door is mounted unchanged on the carriage to the carriage rail, even when the carriage is pivotally displaced in the tilted position. Due to the constant position of the anti-lift device to the carriage rail in all adjustment areas of the sash to the frame, constant protection against lifting is reliably guaranteed.

According to the invention, the carriage is pivotally connected with a recess in its carriage housing to an extension of the anti-lifting device up to the tilting position. The automatic tilting movement of the carriage in relation to the anti-lift device is solved by simply establishing a positive connection. For this purpose, the cross section of the recess is tapered from the upper side to the lower side of the carriage housing, wherein the extension leans against the tapered side in the tilted position of the wing.

For the functional safety of the anti-lift device, it proves to be expedient that at least a part of the outer contour of the anti-lift device, in operative connection with the carriage, almost completely provides a form-fitting adaptation of an inner cross-sectional contour of the carriage rail. If the contours are adhered to, there is a maximum result of the area of the anti-lifting device based on the carriage rail, which has an advantageous effect on the strength and rigidity.

For simple connection of the anti-lifting device to the carriage, the extension arranged in one piece or by means of a positive or non-positive connection to the base plate of the anti-lifting device has a cutout. Furthermore, the carriage housing, starting from the upper side, preferably has a threaded bore extending into the recess, the threaded bore and the cutout being able to be coupled by screwing in a clamping screw and anchoring the carriage with the anti-lift device.

The connection of the anti-lift device to the carriage proves to be simple and effective for a movable coupling in such a way that when the non-positive position of the clamping screw in the threaded hole of the carriage housing with the carriage, the clamping screw in the cutout of the extension when the wing is tilted, can be pivoted with the carriage is relocatable. The positive locking of the clamping screw with the recess enables a play which can be adjusted by screwing in or out by the clamping screw, so that the carriage can be moved into a tilted position by the coupling without resistance by the coupling.

A further advantageous embodiment consists in that for simplified screwing in and subsequent adjustment of the position of the clamping screw, the clamping screw has a tool engagement for a handle, not shown, which is accessible from the upper side of the carriage housing. The handling by means of the handle and the arrangement of the tool intervention for simple assembly or disassembly of the anti-lift device require the usual professional knowledge and can therefore not be manipulated improperly and without authorization, so that security against lifting the sash is permanently guaranteed.

A particularly preferred embodiment with an advantageous embodiment of the anti-lift device is achieved in that the anti-lift device consists of a base plate, the extension and a slide plate which has an outer contour which is adapted to the outer contour of the base plate with a slightly enlarged circumference. Due to the enlarged outer contour of the slide plate, the complete anti-lift device is moved in a sliding manner by moving the sash to the frame with the carriage on the surface of the outer contour provided by the slide plate. In addition, the anti-lift device is supported by the enlarged sliding plate without restrictions and without tension during a tilting movement of the wing. Accordingly, the anti-lifting device is not claimed and is not subject to wear in the assembled state. Frictional resistance and noise are negligible due to the sliding plate on the anti-lift device.

To achieve high strength and thus an effective anti-lifting device, the base plate and the extension are made of a metallic material. This also results in a space-saving arrangement. The active anti-lift protection of the anti-lift device works due to the positive locking with minimal play to the carriage rail and the carriage. The effect of the lifting protection is made possible solely by the base plate, the base plate being guided hooked into the U-shaped rear grip of the carriage rail with the one-piece attached securing anchor.

An additional contribution to reducing the frictional resistance and noise is promoted by the fact that the sliding plate is preferably made of a plastic. Direct contact of the metal base plate to the carriage rail does not occur in normal functional operation, since the slide plate, with its circumferential surface slightly enlarged relative to the base plate, is primarily approximated to the carriage rail. Even if the slide plate is not present or is functionally restricted, the safety of the anti-lift protection is guaranteed by the base plate.

This makes it possible for the anti-lift device with the sliding plate, in particular when moving in the parallel parked position of the wing, to slide with the carriage in the carriage rail with the flat outer contour abuts, the base plate assumes the active resistance against lifting the sash in the closed position, the closed position means the contact position of the sash and the position locked to the frame by the fitting. Furthermore, the resistance to lifting is also formed in the parallel position and in the tilt-open position of the sash to the frame. In all of the switching positions and positions of the wing described above, the anti-lift device remains in the unchanged position in the carriage rail, and the securing anchor in the support shoulder formed by the carriage rail with a U-shaped rear grip.

It has also proven to be advantageous for the function, assembly and cost of the fitting that the anti-lift device can be mounted on the carriage independently of the fitting. The size and weight of the window or door also determine the number of carriages, and regardless of this, the anti-lift device can also be installed several times to increase the anti-lift protection if necessary.

Preferred exemplary embodiments of the invention are shown schematically in the drawing and are explained in more detail below with reference to the figures of the drawing.

The 1 to 6 The drawing shows a window or a door 3 which has a fixedly mounted sash or a fixed door panel 30 in a fixed frame 4 and which are also equipped with a movable sash 2.

The movable wing 2 can be relative to the fixed frame 4 and the fixed wing or door panel 30 from the in the 1 and 2 indicated closed position are on the one hand brought into the tilt position, as in the 3 and 4 you can see. In a further embodiment or by means of further structural components of the fitting 31, the wing 2 can be compared to the fixed frame 4 and the fixedly mounted wing or fixed door panel 30 but on the other hand also bring it into a secured parallel ventilation position or into a parallel position, in which case the sash 2 can be moved in the horizontal direction in front of the permanently installed sash or the fixed door panel 30 from the area of the through opening 32 of the fixed frame, such as from the 5 and 6 can be seen.

So that these four positions of the wing 2 relative to the fixed frame 4 and to the fixed wing or to the fixed door panel 30 are possible, a special fitting arrangement is provided between the wing 2 and the fixed frame 4, namely a so-called parallel sliding and tilting wing system or sliding wing system, of the or in the 1 to 6 for the sake of simplicity, only an operating handle 33 on the wing 2 and an upper opening device 34 and lower carriage 5 between the wing 2 and the fixed frame 4 can be seen.

The upper raising device 34 and the lower carriage 5 with raising arms 8 can be designed kinematically similar to one another. In principle, however, you can also obtain different configurations. In the upper opening device 34, it must be ensured that its frame-side articulation points follow in a horizontal sliding guide 35 Fig. 7 constantly intervene on the upper cross member of the fixed frame 1 and a synchronous movement of its extension arms is ensured.

The lower carriages 5 are to be designed in such a way that they carry the weight of the movable wing 2 securely while they interact with a carriage rail 9 on the lower cross member of the fixed frame 4.

Both the closing-side as well as the opening-side carriage 5 have an extension arm 8 as shown in FIGS 7 to 18 is shown. Each of these extension arms 8 is about an essentially vertical bearing point 7 behind 8, 9 and Fig. 14 pivoted to the carriage 5. Both carriages 5 are each equipped with two rollers 6 which are freely rotatable in the essential horizontal axes and by means of which they follow 1 to 7 , movably supported on the carriage rail 9 of the fixed frame 4 parallel to its plane. The extension arm 8 can also be rotated at its end facing the wing 2 stored.

The two arms 5 carrying the outrigger arms 8 stand together, for. B. via a coupling rod 36 in a fixed connection, which in Fig. 7 is partially and dash-dotted. With the help of this coupling rod 36, the load-bearing carriages 5 are constantly kept at a constant distance from one another. The wing 2, the two carriages 5 with the coupling rod 36 and the two extension arms 8 together form a handlebar parallelogram. With the help of this parallelogram of the handlebar, the wing 2 can be transversely to its plane and also transversely to the plane of the fixed frame 4 between Fig. 2 defined closing position and the in 5 and 6 recognizable parallel positions of the wing 2 adjust, he also in the 3 to 4 intermediate functional positions shown passes.

While at the in 3 and 4 shown position of the opening device 8 easily a movement of the wing 2 from the 1 and 2 corresponding closing positions in the from 3 and 4 apparent tilt position is possible, the wing 2 in the position corresponding to the parallel storage position of the opening device 8 after 5 and 6 horizontally in the direction of arrow 37 Fig. 7 apparent opening position can be moved.

So that the wing 2 relative to the fixed frame 4 after its locked closed position 1 and 2 , in the unlocked closed position, in the tilted position 3 and 4 and in the horizontal parallel storage position 5 to 7 constantly secured against the fixed frame 4 against being lifted out of the carriage rail 9, and thus precludes inoperability and provides security against break-in, it is necessary for the wing 2, which can be moved in parallel, to act as a so-called sliding-tilting wing system or sliding wing system of the window or door 3 to 8 to 18 has at least one anti-lifting device 1. When the anti-lifting device 1 is inserted into an open end of the carriage rail 9, the anti-lifting device 1 can be connected to one end 10 of the carriage 5 and is guided in the carriage rail 9 so as to be displaceable with the carriage 5. For this purpose, a securing anchor 11 attached to the anti-lifting device 1, for example, reproduces 8, 10 and Fig. 18 , with intervention in one on the carriage rail 9 by a support shoulder 12 forming U-shaped rear grip 13, a positive connection. With slidable seat of the support shoulder 12 in the rear grip 13 and connection of the anti-lift device 1 with the carriage 5, the carriage 5 and thus the wing 2 in the vertical direction from the wing 2 to the frame 4 and in the cross section of the window or the door 3 in the horizontal direction from the wing 2 to the frame 4 held securely guided. In order to secure the wing 2 to the frame 4 against lifting out of the carriage rail 9, the form-fitting connection of the support shoulder 12 in the rear grip 13 of the carriage rail 9 and the form-fitting contour 38 of the anti-lifting device 1 to the convex track 39 for the rollers 6 of the carriage 5 cooperate , The rollers 6 are supported on the carriage rail 9 so as to be displaceable. The support shoulder 12 and the raised rail 39 of the carriage rail 9 are aligned facing each other and secure the window or door 3 against lifting out transversely to the plane of the wing 2 and also transversely to the plane of the compound by the form-fitting sliding on the carriage rail 9 fixed frame 4 in the direction of the parallel position of the wing 2.

The anti-lifting device 1 is in the - not shown - closed position, in the position of the anti-lifting device 1 present in a parallel displaceable position Fig. 10 and in the tilt position Fig. 15 of the wing 2 of the window or the door 3 mounted on the carriage 5 to the carriage rail 9 positioned unchanged, the carriage 5 in the tilted position after Fig. 15 without pivoting the anti-lifting device 1.

The 8, 11 and Fig. 16 It can be seen that the carriage 5 is pivotally connected with a recess 15 in its carriage housing 14 to an extension 16 of the anti-lifting device 1 up to the tilting position, the cross section of the recess 15 from the upper side 17 to the lower side 18 of the carriage housing 14 is tapered.

It has been proven for the functional safety of the anti-lifting device 1 8 and 10 It is expedient that an outer contour 19 of the anti-lifting device 1, in operative connection with the carriage 5, provides a form-fitting adaptation of an inner cross-sectional contour 20 of the carriage rail 9. In compliance with the Contours results in a maximum result for the surface of the anti-lifting device 1 against the carriage rail 9, which has an advantageous effect on the strength and rigidity.

For simple connection of the anti-lifting device 1 to the carriage 5, the extension 16 arranged in one piece or by means of a positive or non-positive connection to the anti-lifting device 1 has a cutout 21. Furthermore, the carriage housing 14, starting from the upper side 17, has a threaded bore 22 extending into the recess 15, the threaded bore 22 and the cutout 21 being able to be coupled by screwing in a clamping screw 23 and anchoring the carriage 5 rotatably with the anti-lifting device 1.

With the non-positive position of the clamping screw 23 in the threaded bore 22 of the carriage housing 14 with the carriage 5 behind Fig. 11 and Fig. 16 , in the coupled and positionally fixed position of the carriage 5 with the anti-lift device 1, the clamping screw 23 in the cutout 21 of the extension 16 when the wing 2 is tiltable can be displaced with the carriage 5. The positive engagement of the clamping screw 23 with the recess 21 has play, so that the carriage 5 moves into a tilted position due to the coupling Fig. 16 can be transferred.

To simplify screwing in and then adjusting the position of the clamping screw 23, the clamping screw 23 detects Fig. 8 a tool engagement 24 for a - not shown - handle, which is accessible from the upper side 17 of the carriage housing 14.

Especially after the Fig. 8 it can be seen that the anti-lift device 1 consists of a base plate 25, the extension 16 and a slide plate 27 which has an outer contour 26 which is adapted to the outer contour 19 of the base plate 25 with a slightly enlarged circumference. Due to the enlarged outer contour 19 of the base plate 25, is Fig. 7 the complete anti-lift device 1 when shifting by moving the wing 2 to the frame 4 with the carriage 5 on the reduced area of the outer contour 19 after Fig. 12 slidably guided. Frictional resistance and noise caused by the anti-lifting device 1 are therefore negligible. In addition, the slide plate 27 has a recess 28 which is congruent with the recess 15 of the carriage housing 14 in order to allow the carriage 5 to tilt with the wing 2.

To achieve high strength and thus an effective anti-lift device 1, the base plate 25 and the extension 16 are made of a metallic material. An additional contribution to reducing the frictional resistance and noise is promoted by the fact that the sliding plate 27 is preferably made of a plastic.

After 1, 3 and 5 it is clear that the anti-lift device 1 is slidably guided with the carriage 5 in the carriage rail 9 with a flat outer contour 26 by the slide plate 27, in particular when moving in the parallel position of the wing 2. The base plate 25 forms the active resistance to lifting the wing 2 in the closed position, in the parallel position and in the tilt-open position to the frame 4.

In all the switching positions and positions of the wing 2 described above 1 to 7 , the anti-lift device 1 remains in the unchanged position of the Fig. 10 and Fig. 15 in the carriage rail 9. In addition, the securing anchor 11 of the base plate 25 is also positively bound to the carriage rail 9 in the rear grip 13 formed by the support shoulder 12 in a U-shape.
