Description

The The invention relates to a relief arrangement with which at least a part of the wing load of a wing of a window, a door or the like on a fixed enclosure transferable is, with a facing-side and a wing-side Abutment and arranged between the abutments load transfer element, wherein at least one of the abutment is a stationary abutment part and a relative to the fixed abutment part movable abutment part has and disposed between the abutment parts a spring arrangement is.

From the EP 1 837 472 A1 is a window, a door or the like having a fixed skirt and an opening and closing wing, with a wing load transfer device for introducing at least a part of the wing load into the fixed enclosure, a facing side and a wing side abutment arrangement for supporting a load transfer means and one therewith cooperating, a occurring during an opening and closing operation of the wing distance change between the abutment assemblies compensating distance compensation device known. The distance compensation device comprises a spring arrangement, which always causes a vertically acting spring force component which is directed counter to a vertical weight force component of the weight force of the wing or the wing load and is always smaller than the vertical weight force component.

at this wing load-bearing device must be the part of the wing load-bearing device, having the spring assembly, are installed so accurately that in use, the spring assembly the right bias having. Furthermore, when installing the grand piano does not need only the wing itself can be placed on a corner bearing, but also the load transfer means must be properly positioned, which makes assembly difficult.

From the unpublished German patent application DE 10 2007 024 742.9 It is known to provide a toggle lever in a relief arrangement for a window, a door or the like, with which the bias of the spring assembly can be subsequently generated. In this device, however, a user has no information as to whether the correct bias voltage has been generated.

task Therefore, it is the object of the present invention to provide a relief arrangement to provide it even with somewhat inaccurate assembly of the discharge arrangement or parts thereof, the correct bias of the spring assembly adjust and control.

Solved This object is achieved by a Relief arrangement of the aforementioned type, wherein a tension indicator provided for displaying the state of tension of the spring assembly is. Through the display can be monitored whether the spring assembly at all was placed under a bias and if the bias sufficient is to at least part of the wing load by the discharge arrangement to remove and thus a corner bearing partially of the wing load to relieve.

The Tension indicator can be designed as optical or acoustic display be. For example, when the correct voltage is reached, a LED lights up or an acoustic signal can be given.

at a particularly preferred embodiment may be provided be that one of the abutment parts at least one viewing window, z. B. has an opening. Over the viewing window can be controlled, whether the spring assembly or a part, to in which the spring assembly is supported, in the right one Position is, that is, in a position that indicates that the spring arrangement has the correct bias. Preferably the preload is infinitely adjustable. The viewing window becomes also considered as a visual display. It may be on the moving or the stationary abutment part may be provided. The stationary Abutment part can also have two viewing windows, with over a viewing window the position of the movable abutment part and over the other viewing window monitors the voltage condition can be. The movable abutment part and / or the part of Spring arrangement, which appear in the viewing window in the correct stress state must or the part on which the spring assembly is supported, can a signal color, z. B. red or yellow, to be more visible. The window (s) can as slanted slots or as simple through holes, in particular Through holes, be formed.

Farther can be provided that the stationary abutment part and the Spring arrangement or the movable abutment part in each case a mark or the like. The mark can be, for example the end of the spring assembly or an edge, or a Be edge of a part on which the spring assembly is supported. The marking of the fixed abutment part, for example be the viewing window or a slot of the viewing window. However, there are other markers, such as horizontal Dashes, conceivable, that are reconciled need to make the spring assembly the right preload having.

advantageously, is a tensioning mechanism for generating a bias of the spring assembly intended. The tensioning mechanism is preferably part of the Relief assembly. However, it can also be an external clamping mechanism be used. The tensioned spring arrangement must then in the Clamping position to be fixed properly.

Special Benefits arise when the clamping mechanism is a set screw includes, which is screwed into the fixed abutment part and at least indirectly acts on the spring arrangement. By a set screw can be gradually generated a bias and can through according to wide screwing the screw the preload be generated and set. In particular, the set screw be screwed in until indicated by the tension indicator will ensure that the correct bias is present. A special advantage This is because the stationary abutment part is not precisely positioned must be, but in a vertical direction in different places, or mounted with a certain tolerance on the wing can be. By screwing the set screw can still the correct preload can be adjusted.

The Adjusting screw can taper to a tapering towards the end Pen or pin section act. The pen or pen section can interact with an element, on which the Spring arrangement supported. If thus over the set screw The pin is adjusted in its position, is also the bias the spring arrangement changed.

Thereby, that according to the invention a tension indicator for display the voltage state is provided, the discharge arrangement or at least the load transfer element later be used, for example, if the wing already is placed on the corner bearing fitting. Although the corner fitting must temporarily absorb the full wing load, the assembly but is relieved, since only the corner bearing fitting with the wing must be brought in line and not in addition nor the load transfer element during assembly of the wing must be aligned. Because of that Spring arrangement only later, when the load transfer element is mounted, can be put under tension, this is the procedure possible.

Further Benefits arise when the pin in the stationary arranged abutment part is guided and penetrates the spring assembly. It can be the spring arrangement on a part of the pin and on the stationary abutment part support.

Of the Diameter of the pin can be in a section in the range of the diameter the adjusting screw lie. In particular, the pen in a section have a slightly smaller diameter than the screw. This allows the stationary abutment part made very easily become. A thread can be cut into an opening or hole so that the adjusting screw can be screwed into it. At the same time, the hole in a section as a guide Serve for the pin and can be the set screw directly to act on the pen.

Of the Pin may have a radial thickening, at which the spring assembly supported. For example, the spring assembly can be at the top support the radial thickening and at the bottom of a section of the fixed abutment part. The adjusting screw can be from above acting on the pin and thus the spring assembly under bias put.

If the movable abutment part captive on the stationary abutment part is arranged, the assembly is particularly simple, since the movable abutment part can not be extra held and fixed must while the wing is being mounted. For example can be provided on the movable abutment part embossing be that prevents the movable abutment part of the fixed abutment part triggers.

The Load transfer element can be designed as a rod, which has at least one ball head, which can be clipped into the movable abutment part is.

Thereby designed the connection of the load transfer element especially easy with the movable abutment part. Furthermore is the load transfer element relative to the movable abutment part movable in many degrees of freedom.

It can be provided that the border-side abutment at a Ecklagerbeschlag the window, the door or the like supported. Thus, the load passing through the discharge arrangement is removed from above, for example, on the base plate of the Ecklagerbeschlags, in particular a turn-tilt hardware, act and prevent the corner bearing fitting due to the weight of the wing tilts. The Ecklagerbeschlag can thereby be stabilized. But it can also be especially in wood or Plastic windows should be provided that the load from the base plate and is removed from the vertical part of the window frame. The Relief device can also be claimed as a train on relief device be interpreted.

Of the Clamping mechanism of the relief arrangement can be different Way to be trained. For example, the clamping mechanism include a toggle or an eccentric. This allows the clamping mechanism on mechanically particularly simple way be designed. Farther can be provided that the clamping mechanism two hinged together includes connected rods. In the relaxed state can the rods an angle <180 ° to each other exhibit. In the tensioned state of the spring assembly, they preferably have an angle of 180 ° to each other, wherein they are in this Position can be fixed to each other, z. B. by a union nut.

According to one alternative embodiment can be provided that the tensioning mechanism comprises one or more slides. By The slider can be a pin or pin section that attaches to the Spring arrangement supported, relative to the fixed abutment be moved and set in this position. The postponement can be done in stages by several slides. In this Connection is also a screw or a threaded pin as a slider considered.

According to one alternative embodiment can be provided that the tensioning mechanism has a bevel gear. This can With little effort the preload adjusted precisely become. According to another embodiment can be provided that the load transfer element is designed variable in length. Also As a result, the bias voltage can be changed.

In the scope of the invention also includes a window, a door or the like with a turn-tilt hardware and a relief arrangement according to the invention.

Especially it is preferred if the relief arrangement of the Drehkippbeschlag is disconnected. This means that the discharge arrangement too subsequently with a conventional rotary and / or Tilt & turn hardware can be used and therefore retrofitted is.
