Window or door with relief device

The invention relates to a window or a door according to the preamble of claim 1. Such windows or doors are known and are equipped with either a hinged sash or a tilt-and-turn sash. The hinged fittings connecting the sash to the fixed frame can, on the one hand, be arranged on top of or visibly in front of the opening-side front face of the fixed frame in such windows. On the other hand, it is also possible to use hinged fittings which are installed in a completely concealed position in a chamber between the folds of the sash and the fixed frame. In any case, in these known windows or doors, the stresses resulting from the weight or load of the sash are fully introduced into the fixed frame via the intermediate hinged fittings.

From EP 0 360 024 B1, EP 0 379 866 A1, EP 0385 414 A1 and EP 0 403 774 B1 and DE-PS 328 075, relief devices are known which relieve the hinge fittings of the sash weights and guide them into the frame. EP 0360 024 B1 provides a support device with a support rod which relieves a hinge fitting according to the cross-scissor principle (e.g. US-PS 1 864 164 or US-PS 3 722 142) of the loads of the sash weight. The relief device known from EP 0 379 866 A1, on the other hand, provides a

S200119

Tension element which relieves the joint fittings - using the cross-scissor principle, among other things. The tension element is formed by a Bowden cable, rope, cable or even a tension rod made of solid material and is proposed as a relief device for joint fittings with and without a movable axis of rotation. The relief device according to DE-PS 328 075 proposes relief for joint fittings with a rigid axis of rotation.

The disadvantage of all known relief devices is that when the sash is installed in the frame that is already attached in a building opening, the relief device that is attached to the sash or frame must first be coupled to a corresponding abutment on the frame or sash before the hinge fittings can engage. The relief devices are very flexible due to their task of relieving the hinge fittings in every opening position of the sash. The relief device known from EP 0 360 024 B1, for example, is attached to a support bracket assigned to the sash and is pivotally mounted essentially at this end so that the support rod can follow the axis of rotation shifted by the hinge fittings constructed according to the cross-scissor principle without hindrance.

In the relief device known from EP 0 379 866 A1, the relief device is attached to the frame in the design and the free end of the Bowden cable, rope, cable or tension rod points vertically downwards from the frame-side articulation point due to mobility and gravity. In a completely concealed arrangement, the free end of the tension member is therefore in the rebate area of the frame and can only be coupled to the abutment attached to the sash by manually bringing the free end into a plane in front of the frame and coupling the tension member and abutment.

The aim of the innovation is therefore to design a window or door in such a way that the installation of the sash is simplified.

S200119

This is achieved by the innovation in that the tension or compression member is releasably fixed in a position in which the end that can be coupled to the abutment projects away from the sash or frame into a plane in front of it.

This ensures that the free end of the tension or compression element, which otherwise swings freely, is easily accessible and does not have to be guided or held in place by the sash. When hanging the sash, especially if this is done by a single person, only the sash needs to be guided to the frame and the protruding, held end of the relief device needs to be coupled to the abutment. The detachable fixing of the relief device allows for damage-free movement, in which the sash and the frame can be connected via the joint fittings.

A further advantageous embodiment provides that the tension or compression element is part of a snap-in connection that is attached to the bracket. This ensures a simple design that does not require additional parts that may have to be removed after the sash has been installed.

In order to ensure a simple design of the bracket, it is provided that the bracket has an open pocket for receiving the tension or compression member, in which locking projections are provided which interact with the tension or compression member.

Furthermore, in a window or door where the relief device is designed as a tension member and is suspended at its upper end from the fixed frame, while its lower end engages the abutment mounted on the sash, the tension member is provided to be rigid and consists of a sheathed wire rope. This means that the advantageous effect of the tension member can be used with the installation advantages already mentioned without the deflection angle of the tension member having to be very large. In the case of a pliable

For the tension member, measures must be taken to ensure that the free end of the tension member is at a sufficient distance from the frame plane. On the other hand, the sheathing prevents damage when securing the wire rope.

In addition, it can be provided that the relief device can be fixed in at least one transport position. This ensures that the tension or compression element does not move uncontrollably, which can lead to damage to the frame, for example, during transport or assembly on the building.

Further advantageous embodiments can be seen from the figures. It shows:

Fig. 1 of the drawing shows a window or a door 1 which, in the usual way, consists of a fixed frame 2 and a sash 3. The sash 3 is arranged on the fixed frame 2 so that it can move around a laterally vertical axis 4-4 into a rotating opening position, thus forming a so-called rotating sash. At least one upper hinge 5 and one lower hinge 6 are provided for mounting the sash 3 on the fixed frame 2, with both hinges 5 and 6 being mounted laterally next to an upright sash spar, for example the right sash spar, resting on or visibly in front of the room-side front surface of the fixed frame 2. The hinge parts 5a and 6a fastened to the fixed frame 2 are designed, for example, as so-called tenon hinge parts, while the hinge parts 5b and 6b fastened to the sash 3 are each formed by sleeve hinge parts. The sleeve hinge parts 5b and 6b are placed from above onto the pin hinge parts 5a and 6a and thus form the hinges 5 and 6 which are aligned with the vertical axis 4-4 and around which the sash 3 can be moved relative to the fixed frame 2 from its closed position into the pivoted opening position or vice versa.

A drive rod fitting 8 which can be operated via an operating handle 7 is accommodated in the sash 3 and enables, on the one hand, locking and, on the other hand, unlocking of the sash 3 in the closed position relative to the fixed frame 2 via locking cams 9 and associated locking engagements 10.

In the area of the joint fittings formed by the hinges 5 and 6, a tension member 11 is provided which on the one hand engages the wing 3 and on the other hand is anchored to the fixed frame 2 against the weight or load direction of the wing 3 and is aligned at least approximately parallel to the vertical axis 4-4. This tension member 11 can be a rod-shaped tension anchor. Preferably, however, it is formed by a rope or a cable or it consists of a Bowden cable. According to Fig. 1, the tension member 11 is suspended, for example, via its upper end on the fixed frame 2 in a stationary abutment 12, while its lower end engages the wing 3 by being connected, for example, to the upper end of the sleeve hinge part 6b of the lower hinge 6.

The effective length of the tension member 11 between the abutment 12 and the sleeve hinge part 6b of the lower hinge 6 is dimensioned or set such that it can fully absorb the vertical load component resulting from the weight of the sash 3 in the area of the axis 4-4, without the support surfaces of the sash hinge parts 5b and 6b directed normal to the axis 4-4 having to come into contact with opposite support surfaces of the frame hinge parts 5a and 5b to absorb axial forces in the manner of thrust bearings. The hinges 5 and 6 between the sash 3 and the fixed frame can thus act as pure pivot bearings relieved of axial forces, which only have to absorb the force effects resulting from the horizontal components of the weight or load of the sash 3 - essentially directed transversely to the axis 4-4.

It can be advantageous if the effective length of the tension member 11 between its stationary abutment 12, which is located on the fixed frame 2, and the point of attack on the wing 3 can be varied continuously, at least within certain limits, for example with the aid of a screw member or also by means of an eccentric. This means that it can be placed under tight tension at any time under the influence of the weight of the wing 3 in the direction of the axis 4-4 and the support surfaces between the interacting hinge parts 5a, 5b and 6a, 6b can be relieved of the weight of the wing 3.

However, it is also conceivable to support the tension member 11 with the interposition of a spring element 13 on the stationary abutment 12 of the fixed frame 2 and to adjust the preload force of this spring element 13 to the respective weight of the sash 3 in such a way that its vertical load component does not have to be absorbed by the frame hinge parts 5a and 6a, but is instead introduced directly from the tension member 11 into the fixed frame 2.

Fig. 2 of the drawing shows a window or a door 21 which comprises a fixed frame 22 and a sash 23. The sash 23 is arranged in the fixed frame 22 so that it can move either about a laterally vertical axis 24-24 into a turn-open position or about a lower horizontal axis 25-25 into a tilt-open position. For this purpose, the sash 23 is supported on the fixed frame 22 at the intersection of the two joint axes 24-24 and 25-25 by a corner joint or a turn-tilt corner bearing 26. In addition, there is a pivot joint 27 of a display device 28 at the top between the sash 23 and the fixed frame 22, while a tilt lock 29 is provided between the lower corner of the sash 23 and the fixed frame 22 on the locking side.

A drive rod fitting, adjustable via an operating handle 30, is housed in the sash 23 in such a way that it enables locking and

s 200119 *&iacgr;. ...· *..· &igr; *..*./

-8th-

Unlocking of the wing 23 in the closed position on the fixed frame 22 can be achieved via locking cams 32 and associated locking engagements 33. On the other hand, the drive rod fitting 31 is also designed in such a way that it can be used to engage and disengage a coupling 34, 35 between the wing 23 and the opening device 28 as well as the tilt lock 29. In both the locking switching position and the rotary opening switching position of the drive rod fitting 31, the coupling 34, 35 between the wing 23 and the opening device 28 is in its engaged position.

In the tilt-open switching position of the drive rod fitting 31, however, the coupling 34, 35 is disengaged. The drive rod fitting 31 assumes its locking switching position and its turning-open switching position, while it is engaged in the tilt-open switching position. The opening device 28 is designed as a so-called supporting opening device, i.e. it is suitable for holding the weight of the sash 23 in the locking and turning-open switching positions of the drive rod fitting 31 and for introducing it into the upper, frame-side pivot joint 27. For this purpose, the opening device 28 has an opening arm 36 which is pivotably held in the frame-side pivot joint 27 and which at its other end engages via a collar bolt 37 in a sliding guide 38 which extends essentially parallel to the upper edge of the sash 23 in a pivotable and longitudinally movable manner. In addition, the opening device 28 has an additional arm 39, which on the one hand is exclusively pivotably connected to the sash 23 via a pivot pin 40, but on the other hand is also exclusively pivotably connected to the opening arm 36 via a pivot pin 41. The kinematics of the opening device 28 are designed such that when the sash 23 is tilted open, it keeps the upper sash beam aligned parallel to the upper beam of the fixed frame 2 in every possible tilt position.

In contrast to the window or door 1 according to Fig. 1, in the window 21 according to Fig. 2 the sash 23 is attached to the fixed frame 22 via

S200119

Joint fittings are held in place, which are completely concealed in the air space between the folds of the sash 23 and the fixed frame 22. To form the corner joint or tilt-turn corner bearing 26 as well as the swivel joint 27, joint fittings can be used which, in their mode of operation, are based on the pantograph or stork's beak principle - see, for example, DE-OS 2508 174 and DE-PS 35 19 988 - or which are based on the so-called cross-scissor principle, as can be seen from either US-PS 1 864 164 or US-PS 3 722 142.

In order to relieve the corner joint or tilt-turn corner bearing 26 of the vertical component of the weight or load of the sash 23, a tension member 42 is also used in the window or door 21 according to Fig. 2. It is effective in the direction of the vertical joint axis 24-24 and for this purpose is suspended with its upper end on a stationary abutment 43 of the fixed frame 22, while its lower end engages an abutment 44 that sits on the sash 23. In this case, the tension member 42 with its abutments 43 and 44 is installed above, but still in close proximity to the lower corner joint or tilt-turn corner bearing 26 between the sash 23 and the fixed frame 22, as can be clearly seen from Fig. 2. The tension member 42 according to Fig. 2 can basically have the same design and mode of operation as the tension member 11 according to Fig. 1.

As already schematically indicated in Fig. 2, the tension member 42 is arranged above the joint fitting, which acts as a corner joint or tilt-and-turn corner bearing 26, for example, between the upright beam 22b of the fixed frame 22 and the upright beam 23b of the sash 23, in such a way that it can essentially unfold its effect in the direction of the right-hand axis 24-24. The tension member 42 is located in the area of the rebate clearance between the fixed frame 22 and the sash 23, so that when the sash 23 is in the closed position it is completely concealed between the rebate peripheral surfaces 22c and 23c, as can be clearly seen in Fig. 3. The tension member 42 can be

S200119

-10-

a tension rod made of rigid material. Preferably, however, a rope or cable, in particular made of steel wire, is used as the tension member 42, or a Bowden cable is used. In any case, it is important that the upper end of the tension member 42 is suspended from the peripheral rebate surface 22c of the fixed frame 22 in the stationary abutment 43, while its lower end engages the abutment 44 that is assigned to the peripheral rebate surface 23c of the sash 23. The abutment 44 is preferably arranged on the sash 23 at the shortest possible distance above the lower hinge fitting or corner hinge 26, the tension member 42 being constantly held under tight tension between the two abutments 43 and 44 so that it absorbs the vertical component of the weight or load of the sash 23 without this being able to act on the hinge fitting 26 in the direction of the axis 24-24. This ensures that the hinge fitting 26 only has to absorb forces that result from the horizontal component of the weight or load of the wing 23 and are directed normal to the axis 24-24.

In the simplest case, the abutments 43 and 44 for the tension member 42 can consist of bolts equipped with cross holes or fork slots, which are fastened to the peripheral rebate surfaces 22c and 23c of the fixed frame 22 and sash 23. The tension member 42 is then inserted into the cross holes or fork slots of the same, its effective length being precisely matched and/or adjustable to the distance between the two abutments 43 and 44 as required. Just as in the embodiment according to Fig. 1 of the drawing, it would also be possible according to Figs. 2 to 6 to insert spring elements between one of the abutments 43 and 44 and the tension member 42, the preload force of which can be changed as required and thus - within certain limits - can be matched or adjusted to the respective weight of the sash 23.

The tension member 42 also reliably fulfils the function intended for it, even when the sash 23 is in different relative positions to the fixed frame 22.

• · &bgr; ·

-11-

The change in position of the tension member 42 between its abutments 43 and 44 resulting from each movement of the wing 23 relative to the fixed frame 22 can be easily controlled. If the tension member 42 is made of a rigid material, then it only needs to have cardanic or spherical connections with the abutments 43 and 44 for this purpose. However, if the tension member 42 is designed to be bendable (rope, cable, Bowden cable), then it can easily follow the displacement movements of the wing 23 relative to the fixed frame 22.

A tension rod made of rigid material can be used as the tension member 42, the ends of which engage the fixed frame 22 and the sash 23 through cardanic or spherical connecting members, namely at the abutments 43 and 44 designed for this purpose. However, at least one twistable flat strip material, in particular spring steel strip, can also be used as the tension member 42. Such a flat strip material has the advantage that it can have a relatively large width with a relatively small thickness, this width being essentially limited by the width of the peripheral fold surfaces 22c, 23c of the fixed frame 22 and the sash 23. In the latter case, it has also proven advantageous if the flat strip material of the tension member 42 is aligned with the main planes of the fixed frame 22 and the sash 23 over its entire length when the sash 23 is in the closed position and is in contact with the fixed frame 22, so that it requires only a small amount of installation space when the sash 23 is in the closed position and when the sash 23 is tilted open, while it is subjected to torsion when the sash 23 is rotated open about its upright axis 24-24 - over an angle of approximately 90 degrees. Even if the tension member 42 consists of a rigid tension rod or a twistable flat strip material, it is possible to make its effective length between the abutments 43 and 44 infinitely adjustable, for example with the aid of screw links.

S200119

The arrangement, design and mode of operation of the tension member 42 according to Fig. 2 are evident from Figs. 3 and 4 of the drawing, which show the window or door 21 in which the sash 23 is suspended from the fixed frame 22 via hinge fittings located completely concealed between the horizontal folds, namely the corner hinge 26 and the swivel hinge 27 according to Fig. 2.

In Fig. 3 to 4 of the drawing, only the corner joint or tilt-turn corner bearing 26 can be seen, because in connection with the tension member 42 it is only a matter of the special design of the sash-side joint part 45 of this corner joint or tilt-turn corner bearing 26. It can be seen from Fig. 3 that the sash-side joint part 45 has the shape of an angle piece with two legs 46 and 47 directed at right angles to one another. The sash-side joint part 45 is inserted with its angle legs 46 and 47 into a stepped profile groove 48 of the rebate peripheral surface 23c of the sash 23 in such a way that its outside is flush with the rebate peripheral surface 23c. The upright angle leg 47 of the joint part 45 has a hook attachment 50 which projects like a cantilever over the peripheral fold surface 23c of the upright wing spar 23b and has an angle slot 51 which is open to the side at its lower end. The hook attachment 50 is formed by two hook parts 50a and 50b which are parallel to the wing plane and separated from one another by a gap 50c, which can be clearly seen in Fig. 4. The tension member 42 is provided at its lower end with a block-shaped thickening 52, preferably in the form of a cylinder or spherical body, in which the tension member 42 is anchored either firmly or detachably.

The firm anchoring can be achieved, for example, by casting or pressing the block-shaped thickening 52 with the tension member 42. For a detachable connection, however, the tension member 42 can be inserted into a diametrical hole in the block-shaped thickening 52 and then secured therein by tightening a clamping screw. The sideways opening of the angle slot 51 allows the

S200119

Bring the tension member 42 with its block-shaped thickening 52 into coupling engagement with the hook attachment 50, in which at the same time the tension member 42 is introduced from the side into the gap 50c between the two hook parts 50a and 50b (Fig. 4).

The block-shaped thickening 52 fits snugly in the upper end area of the angle slot 51 against the flanks of the hook parts 50a and 50b of the hook attachment 50, as can be clearly seen in Fig. 3. The hook attachment 50 thus forms the sash-side abutment 44 according to Fig. 2. So that the tension member 42 can be easily coupled to the sash fitting part 45, but cannot be uncoupled again without a certain additional manipulation, a nose-like narrowing projection 53 is assigned to the angle slot 51 in the hook attachment 50 in the area of its sideways opening or immediately above it. This narrowing projection 53 is preferably formed by a spring tongue 54 or a latching catch, which is provided on or in the angle leg 47 of the sash fitting part 45, as Figs. 3 and 4 of the drawing clearly show.

In order to couple the tension member 12 or 42, it is therefore necessary that the block-like thickening 52 protrudes far enough above the plane of the fixed frame 2 or 22 that the hook attachment 50 can be threaded in effortlessly. This is made even more difficult by the fact that the tension member 11 or 42 is attached to the frame 2 or 22 and the associated abutment 12 or 44 is attached to the wing 3 or 33. In order to couple the tension member 12 or 42, the wing 3 or 33 together with the abutment 12 or 44 must therefore be aligned in such a way that, for example, threading the tension member 11, 42 is possible. For example, if the tilt-turn corner bearing 26 or the swivel joint 27 are designed according to US-PS 1 864 164 or US-PS 3 722 142, they cannot be temporarily loaded with the weight of the sash 3, 23. The joints 26, 27 are also only to be attached to the frame when the sash 3 or 33 is in the open position, as they are otherwise hidden. To engage the sash 3, 23,

S200119

-14-

The simultaneous handling of both the wing 3, 23 and the tension member 11, 42 is necessary, which is difficult to handle for a person working alone, especially in the case of heavy wings 3, 23.

Therefore, a device 60 is provided on the abutment 43, with which the tension member 42 is pivoted into the position shown in Fig. 5.

The end of the tension member 42 associated with the abutment 43 is in turn provided with the block-like thickening 61 shown in Fig. 7 and 8, which is essentially cylindrical in shape. The ends of the thickening 61 are pivotably received in bores 62, 63, which are arranged on the one hand in a base body 64 and on the other hand in a cover plate 65. The cover plate 65 overlaps both the base body 64 and a stop 66 to be fixed to the frame 2 or 22 and an adjusting device 67 supported thereon. The cover plate 65 serves not only to visually and protectively cover the abutment 43, but also to connect the movement of the adjusting device 67 and the base body 64. For this purpose, protruding webs 65c on the legs 65a, 65b of the U-shaped profiled cover plate 65 can be positively connected to corresponding recesses 64a or 67a. The adjusting device 67 can be moved relative to the stop 66 using an adjusting screw 68, which rests at its end on the stop 66, whereby when the sash 3, 23 is suspended, the adjusting device 67 is always loaded in the direction of the stop 66.

The cover plate 65 forms a pocket 68 (Fig. 6) with the base body 64 in which the tension member 42 is accommodated at least near its end. In this pocket 68, the tension member 42 can only move to a limited extent perpendicular to the frame rebate surface and is limited in its movement transversely thereto by the device 60 which can be moved together with the base body 64. The device 60 forms three adjacent pockets 69, 70, 71 by means of two locking projections 72, 73 into which the tension member 42 can lock (Fig. 8).

S200119

-15-

In a first position, the tension member 43 is in the middle of the three pockets

69, 70, 71 (Fig. 9). The tension member 42 forms part of the snap-in connection with the circumference of the cable itself. In this position, the tension member 42 is in a secured transport position, so that when the frame 2, 22 moves, it cannot be pivoted in the rotating bearing of the holes 62, 63 and cause damage, e.g. to the frame 2, 22.

In a second position (Fig. 10), the tension member 42 is swung out so that the hook attachment 50 (Fig. 3) can easily engage over the block-shaped thickening 52 when the wing 3,23 is assembled. For this purpose, the tension member 42 is moved into one of the side pockets 69 or 71 and is held in this position independently by the action of the snap-in connection. The longitudinally symmetrical arrangement of the pockets 69,

70, 71 ensures the use of sashes 3 that open to the left and to the right. When the sash 3 is mounted, the tension member 43 is held in a slightly inclined position to the peripheral rebate surface 22c (Fig. 2, 3) and, due to the slight play in the axial direction of the thickening 61, cannot engage so firmly in the pockets 69, 70, 71 that there would be a risk of impairing the function of the joint fittings 6, 46.

It is easily apparent that a certain bending stiffness of the tension member 42 leads to a greater distance of the thickening 52 from the frame 2, 22.

The design of the device 60 in a pressure member is analogous to that of the tension member 42, but here the support is on the frame 2 or 22, i.e. the pocket 68 points upwards. Of course, the adjustment can also be carried out in a different way, so that the arrangement of the adjustment device 67 can also be arranged on the wing.

Other embodiments of the invention may differ from the exemplary embodiments given only as examples. It is also possible to use an additional tension or compression element - e.g.

Clip connection - to be attached bracket to cause an inclination of the tension or compression member. This can, for example, be supported on an edge that delimits the rebate peripheral surface 22c of the frame 2, 22 and would have to be removed after the sash 3, 23 has been installed. However, these could be used multiple times if necessary and made available to the fitter as a tool.
