Description

The invention relates to a concealed Ecklageranordnung with eimen concealed Ecklagerbeschlag and a concealed relief arrangement for a window, a door or the like. For at least partial relief of the concealed Ecklagerbeschlags the sash weight of the window, door or the like., The relief arrangement a pair of scissors includes. Furthermore, the invention relates to a corner bearing assembly and a window, a door or the like.

For concealed fittings of windows, doors or the like, with and without rollover, the sash weight must be absorbed by the concealed fitting. Furthermore, in particular in the case of windows, doors or the like with rollover, the wing must first be opened for opening from the fixed frame so that there is no collision between the rollover and the frame when the wing is opened. For the concealed fitting only a limited installation space is available. In this narrow installation space, a scissors geometry must be provided so that a parking of the wing is even possible. Such a scissors geometry can be designed to remove the weight of the wing or to introduce it into the frame, up to a certain wing weight. Due to the limited installation space, however, the sizing of the scissors geometry limits, so that the scissor geometry can not be designed for arbitrarily high sash weights.

To remedy this situation suggests the EP 0 403 774 B1 a fitting according to the preamble of claim 1, in which larger sash weights can be permitted without the use of tension elements. For this purpose, a bearing axis for a support arm is provided on a hidden lower part of a bearing pin. Its upper end is mounted via an axis on a mounting plate or the vertical leg of a mounting bracket. The sash weight is at least substantially abandoned on this support arm on the fixed frame. The connection of the support arm with a rotary tilting joint and with the mounting plate is designed so that a slight inclination of the support arm is possible.

From the CH 436 024 a parallel fan is known, wherein the lower end of the wing mounted on two outer boom arms.

The EP 0 710 758 A1 describes a relief element which is attached to the side facing away from the corner bearing of the window frame and thus is not part of a Ecklageranordnung.

In the EP 0 385 414 A1 a window is described, which is suspended by a concealed tension member weight-relieved. A support arm is not disclosed.

In the from the DE 38 29 053 C2 Known fitting a support means is provided which is formed by a support rod which is supported with its upper end to a wing frame side support bracket and with its lower end to a Ecklagerwinkel. The disadvantage is that the wing frame which is supported on the support rod subsequently undergoes a lowering movement during the opening of the wing after an initial slight lifting movement.

From the EP 0 436 946 B1 is a concealed lower corner bearing known in which a support rod is provided, which is supported with its lower end on the fixed frame and rotatably supports the wing. The support rod is guided vertically displaceable with its upper end on the wing frame and provided with a hinged approximately centrally on him suspension links, at the lower end of the sash hangs. In this case, the support rod is also pressed laterally against the wing, so that it must be ensured by additional measures that the wing is not turned off by the load transfer from the fixed frame in an undesirable manner.

Object of the present invention is to provide a structurally simple to implement, avoiding the disadvantages mentioned above relief arrangement.

This object is achieved according to the invention in a particularly simple and surprising way by a corner bearing arrangement with the features of claim 1. This means that the one end of the tension arm for direct or indirect, e.g. is formed by an adapter, engaging a wing-supporting fitting part. Such an embodiment of the relief arrangement has the advantage that the relief arrangement engages wing side only at one point and thus exerts no lateral forces on the wing. The relief arrangement according to the invention is intended in particular for partial relief, ie for a partial removal of the wing load.

The tension arm is arranged vertically adjustable on the frame attachment part. In particular, the pulling arm can be arranged to be height-adjustable on the frame fastening part. By this measure, a height compensation can be realized, so that the wing when turning or tilting of the wing due to the relief arrangement is neither raised nor lowered but moves at a constant height.

The height-adjustable and pivotable arrangement of the pull arm on the frame attachment part can be particularly easily realized in that the frame attachment part has a slot in which a fixed on the pull arm arranged bolt is guided. It is understood that a kinematic reversal is also conceivable, namely that a slot is formed on the pull arm and a stationary bolt is provided on the frame mounting part.

Corner bearing fittings often have a pin with a thickening on which a wing is placed, or can be easily equipped with such a pin. A coupling of the relief arrangement with a part of the corner bearing fitting on which the wing load acts directly, can therefore be realized in a particularly simple manner when the tension arm has a fork of the corner bearing fitting under cross-fork at its wing-side end. Thus, the Ecklagerbeschlag particularly easy from the sash weight (partially) be relieved. The wing-side end of the pull arm may also be otherwise, e.g. hook-shaped, be formed. In any case, it is preferably adapted to the possibility of attachment to a fitting supporting the wing.

In a particularly preferred development can be provided that the fork is formed trough-like. This can ensure that the fork and the pin always have a sufficiently large contact surface at different angular positions of the pulling arm.

It is particularly advantageous if the frame attachment part is designed as a part independent of a corner bearing fitting. As a result, the relief arrangement can be particularly easily combined with the Ecklagerbeschlag, which is designed for lower wing loads. By the relief arrangement, it is possible to use the designed for lower wing loads Ecklagerbeschlag even with heavier wings, the relief arrangement removes a portion of the wing load. It is also possible to simply retrofit the discharge arrangement.

In an alternative embodiment it can be provided that the frame attachment part is part of the corner bearing fitting. This has the advantage that the relief arrangement is an integral part of the corner bearing and can be mounted together with it.

In the context of the invention also falls a concealed corner bearing assembly with a relief arrangement described above, and a window, a door or the like. With a fixed frame and at least about a particular vertical pivot axis relative to the fixed frame pivotable wings, wherein a concealed fitting and a relief arrangement as described above are provided.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

The Fig. 1 shows a corner bearing assembly 10, with a concealed corner bearing fitting 11 and a discharge assembly 12. The relief assembly 12 includes a frame attachment member 13 to which a support arm 14 is pivotally mounted. The support arm 14 is also pivotally connected to the pull arm 15, which in turn is pivotally connected to the bolt 16 to the frame attachment part 13. The pulling arm 15 performs a pure pivoting movement in a plane when opening and closing a wing. Unlike known support rods or ropes, he makes no rotational movement. The pulling arm 15 is dimensioned so that it removes a part of its load even with the wing closed. The bolt 16 is arranged vertically displaceable in a slot 17 of the frame attachment part 13.

The pulling arm 15 is angled at its free end 18, wherein the free end 18 is fork-shaped and a thickening 19 of a pin 20 engages behind. On the pin 20, a wing or a wing-side fitting part can be placed. When opening and closing the pin 20 makes a movement perpendicular to the window plane approximately along a straight line. In particular, he does not make a pendulum motion. By the relief assembly 12, the scissors 21 is partially relieved of the sash weight as the wing-supporting fitting part. That's it possible, in particular the arm 22 form thinner, so that it fits with the wing closed in the Falzluftbereich.

The guide 24 is aligned obliquely to the window plane. It could also be curved.

In the Fig. 1 It can be seen that the frame attachment member 13 is separated from the mounting leg 25 of the corner bearing assembly. This allows the relief assembly 12 to be retrofitted and mounted separately.

In the Fig. 2 the relief arrangement 12 is shown in a plan view. When the sash is closed, the frame attachment part 13, the pull arm 15 and the support link 14 are aligned in the fold circumferential direction. Even with the wing closed, the pulling arm 15 engages behind the thickening 19 of the bolt 20. It can be seen that the thickening 19 is curved. For this reason, the fork-like free end 18 of the tension arm 15 has a trough-like depression 26. This ensures that there is always a sufficiently large contact surface between the free end 18 and the thickening 19 at different inclination of the traction arm 15.

This situation can also be seen in the Fig. 3 recognize where the pulling arm 15 is swung out. In this case, the fork-like free end 18 no longer engages directly from below but obliquely from below on the thickening 19. In comparison to Fig. 2 the pulling arm 15 has been moved slightly downwards during its pivotal movement. This can be seen from the fact that the bolt 16 compared to Fig. 2 is shifted downwards. The support arm 14, the pull arm 15 and the positions of the pivot points 27,28 on the frame mounting part 13 and the tension arm 15 and the bolt 16 are coordinated so that in all positions of the bolt 20 is always a constant relief and the bolt 20 in vertical direction is not relocated. This means that the bolt 20 and thus the lower edge of the wing is moved only horizontally.

The Fig. 4 shows a plan view of the corner bearing assembly 10 without the mounting leg 25 and the parts arranged thereon, wherein the position shown corresponds to a closed position of a wing. The corner bearing assembly is particularly designed for use as a concealed fitting. In this context, it should be noted that a solid frame formed as a frame is connected via the corner bearing assembly 10 with a wing. The wing has a rollover. In order to open the wing, the wing must therefore first be turned off the frame. This is made possible by the corner bearing assembly 10, namely by the arm 22 and the tab 50, which form a scissors geometry (see also Fig. 5 ). The geometry of the scissors is designed so that the wing is turned off as little as possible while still providing the greatest possible clearance. To open the wing of this is just turned off so far from the frame, that there is no collision hiss the flashover and the frame.

The scissor geometry is located above a base plate 52, with which attachment to a fixed enclosure, in particular a fixed frame, can take place. In particular, no part projects laterally beyond the base plate 52. In addition, the Fig. 4 can be seen that the elements 22, 50 must be arranged with the sash closed in Falzluftbereich. Therefore, the elements 22, 50 may have only a limited thickness and, in particular, may not be dimensioned as large as would be necessary for large wing loads (if no relief assembly 12 is used).

The pin 51 is moved in the guide 24 in a forward position. By the inclined guide 24, which can also be performed bent, it is possible to build the corner bearing assembly 10 is smaller and more stable overall. In particular, this makes it possible to realize a very small scissors geometry.

The in the Fig. 5 shown position corresponds to an open position of the wing. It can be seen that the location where the bolt 20 is located has been moved approximately along a straight line perpendicular to the window plane. This means that the pulling arm 15 has practically performed a pure pivoting movement.

The weight of the wing is transmitted via the not shown, attached to the wing corner band on the bolt 20. This then transmits the weight on the tab 50. The tab 50 rests on the arm 22 and thus transmits the load to the arm 22. The scissor geometry was chosen so that the greatest possible overlap of the tab 50 and the arm 22 with the wing open is available. Thus, a resulting bending moment is kept small. The arm 22 introduces the sash weight or a portion of the sash weight over the base plate 52 in the fixed frame.

The pin 51 was moved during the opening of the wing in the guide 24 in a rear position. The guide 24 limits the relative movement of the arm 22 and the tab 50.
