A vertical weight component of the weight is arranged against the flank or the load flank and is always smaller than the vertical weight component.

Description

The invention relates to a window, a door or the like. With a fixed enclosure and an openable and closable wing, with a wing load-releasing device for introducing a portion of the wing load or weight of the wing in the fixed enclosure, which has a border-side and a wing-side abutment arrangement for Having a load transfer means and a cooperating with this, a compensating during a Öffen- and / or closing operation of the wing, at least between stationary parts of the abutment arrangements distance compensation compensating distance compensation device.

Wings are usually coupled via a corner fitting with a fixed enclosure, in particular a fixed frame, so that the wing with respect to the fixed enclosure can perform a rotational movement and / or a tilting movement. The weight of the wing must be supported. Often corner fittings have a handlebar assembly that can take no or only a limited weight. Especially with large, heavy wings, the problem of load transfer, without affecting the corner fitting. Another requirement today is to be able to use the same corner fitting for different wing sizes, so that less different components must be stored and manufactured.

In the EP 0 360 024 B1 is proposed for the exclusive load transfer of the wing, that this is supported at least in rotatably open casement on the fixed frame via a device independent of the handlebars of the pivot bearing. In this case, the device comprises a support rod, which at one end on the fixed frame in the region of the lower pivot bearing and the other end at the pivot bearing, for Rotary axis paraiieien frame legs of the sash supported. Since the distance between the two articulation points of the support rod changes when the wing is opened, the wing frame which is supported on the support rod subsequently undergoes a slight lowering movement when the wing is opened for rotation after an initial slight lifting movement.

From the EP 1 301 676 B1 is a window with a mounted on or near an upright boundary edge by hinge fittings on a fixed frame wings with a on the one hand in the hinge fittings on the wing attacking and on the other hand against the weight or load direction of the wing acting on the fixed frame relief device from a wing or Frame mounted block, a hinged thereto train - or pressure member and a detachable, attachable to the frame or wing abutment, known. It can be provided for complete relief of frame hinge parts that the tension member is supported with the interposition of a spring element on the stationary abutment of the fixed frame and while the biasing force of the spring element is adjusted to the respective weight of the wing so that its vertical load component is not absorbed by the frame hinge parts must be introduced directly from the tension member into the fixed frame.

Similar arrangements are also known from DE 39 20 360 C2 . EP 0 385 414 B1 and EP 0 379 866 B1 known.

From the EP 0 851 085 B1 is a fitting for a wing which is pivotally mounted on a frame with a frame corner so that it is rotatable and tiltable known. There is provided a support rod, which is a dependent device without which the fitting does not work. The weight of the wing is introduced via the support rod in the pivot bearing. At the other end of the support rod is a Control means provided which changes the point of application or point of contact of the support rod with its upper end in dependence on how far the wing is open. By the control device, a distance compensation is realized. However, the support rod is exposed to increased wear at its upper end.

Object of the present invention is to remedy this situation.

The object is achieved in a surprisingly simple way by a window, a door or the like. Of the aforementioned type in that the distance compensation device comprises a spring assembly which always causes a vertical spring force component, which is a vertical weight component of the force of gravity Wing and the wing load is directed against and always, that is independent of the wing position, smaller than the vertical weight component. This makes it possible to support a wing during an opening or closing operation without the wing moving vertically upwards. Part of the wing load may be introduced into the fixed enclosure via the wing load-carrying device (and the fixed frame). The remaining portion of the weight is advantageously removed elsewhere, for example by a fitting arrangement, in order to prevent the wing from being displaced vertically downwards during an opening or closing movement. The wing load bearing device is preferably retrofittable so that a fitting arrangement designed for a low sash weight, in particular a corner fitting, can also be used with heavier wings, the additional weight of the heavier wings being borne by the wing load removal device. The spring assembly may be distributed to both end regions or provided in an end region of the load transferring means. However, it is also conceivable to provide the spring arrangement in the load transfer means, in particular spaced from its end regions. The total spring force, which may consist of a vertical and a horizontal component is composed, is preferably proportional to the Ausienkung the spring assembly and thus reacts to the change in distance between the abutments.

It is particularly preferred if the spring arrangement has a spring force which is greater than that of the change in distance and whose vertical component is less than the vertical component of the weight force. As a result, the usable way of the spring arrangement is so great that the Falzlufteinstellung up and down, and installation and manufacturing tolerances can be compensated. A separate, manually operated length adjustment of the load transfer means is not necessary.

Preferably, the spring assembly is biased. This ensures that a fitting is reliably relieved. Depending on the arrangement of the spring arrangement, the wing is not raised, for example, when opening the wing and a change in length of the spring assembly, but the relief of the fitting (corner bearing) is larger, d. H. the force absorbed by the corner bearing becomes smaller and vice versa, the force absorbed by the spring increases. However, it can also adjust the reverse effect, wherein the spring arrangement is designed so that always a part of the wing load is received.

A particularly space-saving and secure arrangement of the spring arrangement results when the spring arrangement is always aligned parallel to a fold circumferential direction, in particular vertically. In this case, the spring force is always directed vertically. So it has only a vertical component.

Advantageously, the spring arrangement is designed as a compression spring arrangement. This can be constructed very easily from disc springs. One of the plates brings great power on a small path. The Disc springs can be arranged in the wrong direction. When alternately arranged disc springs, the force remains the same, but the way increases according to the number of springs. If one or more disc springs are not exchangeable but installed in the same direction, the spring force can be increased. Alternatively, the spring assembly may be formed as a rubber spring or elastomeric material.

In a preferred embodiment, an independent of the wing load-carrying device fitting, in particular corner fitting, be provided which initiates a part of the wing load (weight), in particular a vertical component of the weight, in the fixed enclosure. In particular, in a tilted position of the wing and a horizontal component of the wing load can be introduced into the fixed enclosure. The fact that the fitting and the wing load-carrying device are independent of each other, the fitting can be used in wings lighter weight without Flügelblastabtrageinrichtung. For wings of higher weight, the wing load-carrying device can be retrofitted independently of the fitting. By fitting the vertical position of the wing can be set so that it does not move vertically relative to the fixed enclosure during a pivoting or tilting movement.

In one embodiment of the invention, the load transfer means may be rigid, in particular as a rod, preferably as a support rod formed. If a support rod is provided as the load transfer means, the mount-side abutment arrangement is advantageously arranged below the wing-side abutment arrangement.

The load transfer means may be formed as a traction means. A rod can also be used as a traction device. Preferably, however, come as traction means ropes, Bowden cables or the like. In question. If the load transfer means is designed as a traction means, which is mount-side abutment arrangement preferably disposed above the wing-side abutment assembly.

In one embodiment of the invention can be provided that an abutment assembly is constructed in several parts, wherein a first part is arranged stationary and a second part during an opening and / or closing movement relative to the first part along a guide is movable. This allows the distance compensation. The second part may be designed as a slider. Preferably, the movable part is supported on the spring assembly.

Advantageously, an adjusting device for adjusting the bias of the spring assembly is provided. A re-tensioning of the spring arrangement can also take place. For this purpose, a thread may be provided at the end of the load transfer means, which cooperates with a nut on which the spring arrangement is supported. Alternatively, an abutment assembly may be made in two parts, with one part being stationary and the other part to which the load transfer means may be attached being fixable in different relative positions with respect to the fixed part.

In a preferred embodiment, a deflection device for deflecting the load transfer means may be provided on an abutment arrangement. This makes it possible to arrange the spring arrangement in a fitting part groove to save space. The abutment arrangement can have a funnel-shaped opening as a deflection. The wear of the load transfer means can be minimized thereby.

It when an assembly aid is provided, with which the spring assembly is compressible during assembly of the additional wing load-removal device is particularly advantageous. As a result, the load transfer means can be easily attached to an abutment arrangement. in the scope of the invention also falls a wing load-carrying device of a window, a door or the like. With the aforementioned wing load-carrying device features.

According to the embodiment of FIG. 1, a wing 1, in particular a turn-tilt wing, is pivotally connected to a casement 2 via a fitting 3 designed as a corner fitting with a fixed frame 4 of a border. Part of the wing load of the wing 1 is received by the links 5, 6 and transmitted to the fixed frame 4 and thus the enclosure. An additional load transfer is provided by a wing load removal device 7 which comprises a wing-side first abutment arrangement 8 and a mount-side second abutment arrangement 9 which receive or hold a load transfer means 10. The load transfer means 10 is formed in the embodiment of Figure 1 as a support rod. The enclosure-side abutment assembly 9 is profile-independent and screwed onto a base plate 11 of the fitting 3.

In the sectional view of the wing load-carrying device 7 according to FIG. 2, it can be seen that the border-side abutment arrangement 9 has a spherical recess 15. About the abutment assembly 9, a portion of the weight of the wing 1 in the fixed frame 4 and thus the enclosure is initiated. The load transferring means 10 has spherical ends 16, 17, the end 17 being received in a spherical receptacle 18. The receptacle 18 keeps the load transfer means 10 captive on the abutment assembly 8 due to a rear grip of the spherical end 17.

The abutment arrangement 8 comprises a first part 19 which can be mounted fixedly on the casement 2 and a second part 19 which can be mounted relative to the stationary part 19 The vertical direction movable part 20. The second part 20 is formed as a slider and is slidably received in the first part 19 with a rear grip guide. In the second part 20, the receptacle 18 is accommodated, which braces during assembly in the second part 20. A spring arrangement 21 is arranged between the movable part 20 and a bearing block 22 of the stationary part 19. In this case, the spring assembly 21 is supported on the one hand on the movable part 20 and the other via a shoulder 23 of a receiving pin 24, are threaded onto the disc springs 25, on the bearing block 22 from. The spring arrangement is always aligned vertically. The spring force thus always acts in the vertical direction and has only a vertical component.

The vertical position of the wing 2 during a Öffen - or closing movement is determined by the fitting 3. Since, during an opening or closing movement, the distance between the abutment arrangements 8, 9 (at least their stationary parts) changes, since the load transfer means 10 moves from a substantially vertical orientation in a closed position of the wing 1 into an inclined position sweeping through the rebate air area with the wing 1 open is pivoted, a length compensation must be created. This is done on the one hand by the movable part 20 and the other by the spring assembly 21. In an inclined position of the traction means 10, the movable member 20 moves down so that the spring assembly 21 relaxes slightly (the vertical position of the first part 19 is retained because the wing 1 does not shift vertically). This means that the spring force is reduced slightly, but only so slightly that the wing 1 is still supported with. The spring assembly 21 thus causes the vertical distance of the part 20 is compensated in the abutment assembly 8, with simultaneous partial removal of the blade weight. With an appropriate number of disc springs 25, the adjustable Falzluftverstellung the fitting 3 is compensated by the disc springs 25. Thus, an additional retightening on the wing load-carrying device 7 is not necessary. Similarly, manufacturing and installation tolerances can be taken into account by additional springs. There the wing load bearing device 7 only relieves the fitting 3, so only a portion of the sash weight is removed via the wing load bearing device 7, the height adjustment in the fitting 3 may remain.

For example, disc springs 25 can be used with a spring force of about 660 N. Spring assemblies 21 with such disc springs 25 can be used for wing 1 with a weight of nearly 150 kg, with about 80kg are removed by the fitting 3. The weight can be increased even if at least some disc springs 25 are installed in the same direction.

According to the embodiment of FIG. 3, a wing 31 designed as a turn-tilt wing is pivotably connected to a casement 32 via a fitting 33 designed as a corner fitting with a fixed frame 34 of a fixed enclosure. Part of the wing load of the wing 31 is received by the fitting 33 and transmitted to the fixed frame 34. Additional load transfer is provided by a wing load-carrying device 37, which comprises a collar-side first abutment arrangement 38 and a wing-side second abutment arrangement 39 which receive or hold a load-transferring means 40. The load transfer means 40 is formed in the embodiment of Figure 3 as a cable.

In the sectional representation of the lower abutment arrangement 39 according to FIG. 4 a, it can be seen that the abutment arrangement 39 has a first part 45 which can be mounted fixedly on the casement frame 32. Relative to the stationary part 45, a second part 46 is vertically movable, wherein the part 46 is guided in a guide 47. The stationary part 45 has two components, namely a lower part 45.1 and a cover part 45.2, wherein the guide 47 is formed between the lower part 45.1 and the cover part 45.2. In order to prevent falling apart of the parts 45.1, 45.2, a pin connection is provided. In the guide 47, a spring assembly 48 is also arranged, which is located on the movable part 46 is supported. With the movable part 46, the load transfer means 40, not shown here, can be coupled. Upon an opening movement of the blade 31, the preloaded spring assembly 48 is compressed by a change in distance between the abutment assemblies 38,39 without significant change in the spring force. A part of the vertically directed weight force is therefore always absorbed by the spring assembly 48, wherein the spring force also acts vertically here, since the spring assembly 48 in the vertical direction (Falzumfangsrichtung) is aligned.

On the cover part 45.2 a funnel-shaped opening 49 is formed, through which the load transfer means 40 extends. The funnel-shaped opening 49 has the function of a deflection for the load transfer means 40. Although the abutment assembly 39 partially covers a fitting part 33.1 of the fitting 33, is fundamentally independent of this. The fitting 33 can also be used independently of the abutment arrangement 39.

In FIG. 4b, the abutment arrangement 38 is shown in a sectional representation. The abutment assembly 38 is constructed in two parts. A part 51 has a receptacle 52 in the form of a bolt, to which the load transfer means 40 can be fastened, in particular suspended, can be. The part 51 is movable relative to the part 54 by means of an adjusting device 53 designed as an adjusting screw, which is supported on the part 54. In addition, a basic setting, in particular a bias of the spring assembly 48, make. During operation, ie during an opening or closing movement, the parts 51, 54 are not movable relative to each other.

In the figure 5a, the abutment assembly 39 is shown with removed cover part 45.2. Here it can be seen that on the load transmission means 40, a bolt 55 is arranged, which is in a recess 56 of the movable member 46 is positively connected to which the spring assembly 48 is supported. At the other end, the spring arrangement 48 is supported on a shoulder 57. The part 46 has a passage opening, which projects through the load transfer means 40.

FIG. 5b shows a perspective view of the cover part 45.2. Here is clearly the funnel-shaped opening 49 can be seen.

According to the embodiment of FIG. 6, a wing 61 designed as a turn-tilt wing is pivotally connected to a casement 62 via a fitting 63 designed as a corner fitting, to a fixed frame 64 of a fixed enclosure. Part of the wing load of the wing 61 is received by the fitting 63 and transmitted to the fixed frame 64. An additional load transfer is provided by a wing load removal device 67, which comprises a surround-side first abutment arrangement 68 and a wing-side second abutment arrangement 69, which receive or hold a load transfer means 70. The load transfer means 70 is formed in the embodiment of Figure 6 as a rod. In this embodiment, however, it would also be conceivable to rigidly form the load transfer means 70 only in the area of the upper abutment arrangement 68 and to make it flexible in the lower area, in particular as a cable pull.

In the detailed illustration shown in FIG. 7, it can be seen that the load transfer device 70 passes through a bolt 71 and a spring arrangement 72. The pin 71 may be pivotally mounted on the stationary part 73 of the abutment assembly 68 or have such a large passage opening that a pivotal movement of the load transfer means 70 is not hindered. The spring assembly 72 is supported at one end on the bolt 71 and the other end to a nut 74 which is screwed onto a thread at the free end of the load transfer means 70. A change in distance between the abutment assemblies 68, 69 is received by the spring assembly 72, which is formed as a compression spring. When opening the wing 61 is additionally compresses the spring assembly 72, so that the spring force increases. The vertical component of the spring force is still less than the vertical component of the weight of the wing 61. This ensures that the wing is not lifted when opening.

For assembly, the mounting aid 75, the bolt 71 and the spring assembly 72 are preassembled on the load transfer means 70. About the mounting aid 75 and the nut 74, the spring assembly 72 is compressed, so that the load transfer means 70 is as far as possible down over the pin 71 protrudes. The mounting aid 75 is formed as a nut which is adjustable in the longitudinal direction of the load transfer means 70. As soon as the free end of the load transfer means 70, which in the exemplary embodiment is designed as a hook 76, is fastened to the abutment arrangement 69 (FIG. 8), the assembly aid 75 can be released so that a relative movement of the load transfer means 70 with respect to the bolt 71 is made possible.

As can be seen from FIG. 8, the abutment arrangement 69 in this exemplary embodiment consists only of a tab 77 which is fixed in place on the sash frame 62. The tab 77 forms a rear grip for the hook 76.
