The wing frame and a stick frame (1) move relative to each other by actuating an actuating unit, so that the window is openable and closable. An additional fitting has a lever arm, which is pivotably supported at the stick frame by a pivoting support and is pivotable at the wing frame by another pivoting support. The lever arm is slidably supported at the wing frame along a displacement direction (V). Another actuating unit actuates the additional fitting by applying force to the latter actuating unit.

Description

The The present invention relates to a fitting for power operated Parallel opening.

Such a fitting is for example from the DE 197 41 728 A known. In this known fitting comprises a release mechanism at least four acting on a window sash and attached to the window frame Ausstellscheren. Each of the Ausstellscheren has a release lever, a control lever and a drive lever. The release lever connects window sash and window frame with each other and is rotatably mounted at a first end and rotatably mounted at a second end and slidably. The control lever is rotatably coupled to the deployment lever and connected at one end to the window frame. The mechanism is actuated by a drive lever which is rotatably coupled to the Ausstellscheren.

The maximum load capacity of such Ausstellscherenmechanismus however, is very limited in terms of maximum sash weight and a maximum wind load at which the window is still functional is. In addition, a and opening direction acting force very strong and is especially close to the closed Position or in the closed position relatively low. That is why it is difficult to provide the window with sufficient Press closing force against the seal to a good to ensure tight closing of the window.

DE 202 20 865 U and GB 2323 407 A show similar mechanisms of a Parallelausstellfensters.

It There is thus a need for improved fitting a Parallelausstellfensters, the above disadvantages of State of the art avoids. The object of the invention is thus in the creation of a fitting as well as a window with Fitting, the easy to operate and with low Costs can be produced and a high clamping force for Pressing a window seal can produce.

These The object is achieved by a fitting with the features of claim 1 and a window with the features of claim 6 solved. Advantageous developments are in the dependent claims Are defined.

• A lever arm with an actuating device which is pivotably mounted or storable by means of a first pivot bearing on a floor frame of a building opening and which is pivotally mounted or storable on a casement by means of a second pivot bearing on a casement and can be stored along a direction of displacement V.
• A support arm, which is pivotally mounted on the lever arm by means of a third pivot bearing and is pivotally mounted or storable by means of a fourth pivot bearing on the casement,

wherein the fitting is configured such that the fitting is operable by applying a force to the actuator.

to A description of the geometrical arrangements will be given below Cartesian coordinate system used, wherein the z-direction (perpendicular or vertical) substantially perpendicular to the earth's surface aligned and pointing away from the center of the earth. Perpendicular to it in the horizontal, the x-direction and the y-direction, so that the x, y, and z directions are right-handed Coordinate system result. Without loss of generality It is assumed that the floor frame is inside a building opening a vertical wall is arranged so that the floor frame extends substantially parallel to the x-z plane with y = 0. Areas that are relative to any point in the y direction are called "building side" called. Analogous are areas that are relative to any point opposite to the y direction are called "weather side".

It It is understood that the coordinate system in relation to the coordinate system the earth can be turned. For example, the floor frame a window on a roof slope against the perpendicular tilted so that the z-direction is not the Corresponds to perpendiculars, but a linear combination of the perpendiculars and a perpendicular to horizontal. Corresponding the x and y directions perpendicular to the z direction in pairs turned. For roof hatch for flat roofs corresponds the z-direction is substantially horizontal and the y-direction essentially the perpendicular.

The term "substantially" may in this case describe a slight deviation from a desired value, in particular a deviation within the manufacturing accuracy and / or in the context of the necessary accuracy, so that an effect is maintained as it is present at the desired value. The term "essentially" can therefore a deviation of less than about 30%, less than about 20%, less than about 10%, less than about 5%, less than about 2%, preferably less than about 1% of a target position, etc. The term "substantially" includes the term "identical", ie without deviation from a setpoint, a desired position, etc.

Of the Wing frame can be a different coordinate system with the directions x ', y' and z 'span, with the sash extends substantially parallel to the x'-z 'plane. are Stock frame and sash arranged parallel to each other, so the directions x ', y' and z 'each fall with the directions x, y and z together. In contrast, the sash can, however be tilted relative to the floor frame, so that only the x'-direction coincides with the x-direction and the z'-direction is a linear combination of the y and z directions.

The first pivot bearing of the lever arm is on the floor frame of the building opening, in particular a window, pivotally or rotatably mounted or attached thereto or storable or attachable. Hereinafter is called "pivoting" in particular also understood as "rotatable". This means, that by the first pivot bearing a first pivot axis is defined, by which the lever arm is pivotable, wherein the pivot axis is preferably horizontal (in the x direction). In other words, the first pivot bearing on the lever arm acting vertical and / or horizontal directional forces (z- and / or y-direction) record and divert into the floor frame, whereas torques acting about the first pivot axis do not occur be transferred to the floor frame.

through of the second pivot bearing is the lever arm the sash pivoted or rotatably mounted or storable. Next is the lever arm displaceable along a direction of displacement V on the casement stored or storable. In other words, by the second Swivel bearing defines a second pivot axis about which the lever arm is pivotable or is rotatable, wherein the pivot axis is preferably parallel to horizontal extension of the sash (x'-direction) runs. Next is the position of the second pivot axis displaceable along the displacement direction V. This means, that the second pivot bearing acting on the lever arm perpendicular absorb forces directed to the direction of displacement V. and can divert into the sash frame, whereas around the second pivot axis acting torques and along the direction of displacement V acting Forces are not transmitted to the sash become. In this case, the displacement direction is preferably parallel to one of the longitudinal extensions of the sash, in particular essentially parallel to the vertical or to the z 'direction.

Further the fitting has a support arm, which by means of third pivot bearing on the lever arm pivotally mounted or rotatable is, wherein the pivot axis is preferably horizontal (in the x direction) runs. By means of the third pivot bearing can acting on the support arm vertical and / or horizontal directed forces (z and / or y direction) transmitted to the lever arm be, but no torques, which about the third pivot axis Act.

Of the Support arm is by means of the fourth pivot bearing on the sash pivotally mounted or can be stored there. In other words defined by the fourth pivot bearing a fourth pivot axis, about which the support arm is pivotable or rotatable, wherein the pivot axis preferably parallel to the horizontal extent of the sash (x'-direction) runs. The fourth pivot bearing can acting on the support arm directed Take up forces (along the y '- / z' direction) and in the Divert wing frame, whereas about the fourth pivot axis acting torques are not transferable.

Of the Fitting is by applying a force to the actuator actuated, so that the first pivot bearing, for example by means of an actuator, beispielswelse a Crank, an engine, a gearbox, a worm, a coupling rod, a cable and / or a chain or the like, pivoted can be. In particular, when the longitudinal extent of the Lever arm parallel to a horizontal (i.e., parallel to the through the x- / y-direction spanned plane) runs, acts upon introduction of a force along the z-direction, which in particular the direction of deviation V corresponds indirectly over the fourth pivot bearing in the lever arm a maximum torque at the first pivot bearing.

Preferably is the actuator of the lever arm as substantially formed coaxially with the first pivot bearing arranged toothed segment.

Preferably is the actuator of the lever arm designed, to be positively connected to a coupling rod.

wobei sich der Stockrahmen und der Flügelrahmen durch Betätigen der Betätigungseinrichtung relativ zueinander bewegen, so daß das Fenster öffenbar und schließbar ist.According to one aspect, a window, in particular a parallel exposure window, is provided, comprising:

• - a floor frame,
• - a sash and
• - At least one fitting, each fitting having a lever arm which is - pivotally mounted by means of a first pivot bearing on the floor frame, - is pivotally mounted by means of a second pivot bearing on the sash and slidably along a displacement direction V on the sash and - has an actuator which is designed to operate the fitting by applying a force to the actuator and

having a support arm, which

• - Is pivotally mounted by means of a third pivot bearing on the lever arm and
• - Is pivotally mounted by means of a fourth pivot bearing on the sash, and

wherein the floor frame and the sash move by actuating the actuator relative to each other, so that the window can be opened and closed.

As already described in terms of fitting, is the first Swivel bearing of the lever arm pivotable on the floor frame of the window rotatably mounted or attached thereto or storable or fastened, which is why the first pivot bearing acting on the lever arm vertically and / or horizontally directed forces (z and / or y direction), but not around the first pivot axis acting torques, on transfers the floor frame.

On the other hand the lever arm is pivotable by means of the second pivot bearing slidably mounted on the sash, d. H. the lever arm is along a direction of displacement V on the sash displaceable. In this case, the displacement direction V is preferably parallel to one of the longitudinal extensions of the sash, in particular substantially parallel to the z 'direction or to the vertical. Therefore, acting on the sash forces only to that extent transmitted via the second pivot bearing on the lever arm Be as that only perpendicular to the direction of displacement V directed force component is transferable. Especially However, the weight of the sash essentially acts along the direction of displacement V when the sash aligned parallel to a vertical building wall is. In the event that the sash inclined to the horizontal, so the direction of displacement V is an angle different from zero with respect to the z-direction has, for example, in windows in sloping roofs or Roof hatches, the weight of the sash can at least partially transmitted to the lever arm via the second pivot bearing become.

Of the Support arm is by means of the third pivot bearing on the lever arm and by means of the fourth pivot bearing on the sash pivoted. Because by means of this pivot bearing vertically and / or horizontally directed forces (y- and / or z-direction or y 'and / or z' direction) are transmitted to the lever arm can, is the weight of the sash transmitted to the lever arm by means of the support arm.

Of the Fitting is by applying a force to the actuator actuated, so that the first pivot bearing, for example by means of an actuating device, for example a Crank, an engine, a gearbox, a worm, a coupling rod, a cable and / or a chain or the like, pivoted can be, with the actuator particularly preferably arranged on the floor frame or with the floor frame connected is. In particular, when the longitudinal extent of the Lever arm parallel to the horizontal (ie parallel to a through the x- / y-directions spanned plane) runs, acts upon introduction of a force along the z-direction, which in particular the displacement direction V, indirectly via the fourth pivot bearing in the lever arm a maximum torque at the first pivot bearing. The opening width of the Window substantially the length of the lever arm, d. H. the distance between the first and second pivot bearings of the lever arm. Advantageously, the required installation depth of the fitting or of the window to achieve a predetermined opening width essentially by the extension of the lever arm in the direction perpendicular or transverse to the longitudinal extent determined and thus low. Further advantageously, the lever arm in dependence from the desired opening width accordingly be formed short, so that the lever arm advantageously an increased weight of the sash and / or increased wind forces acting on the sash can absorb or support.

In a Parallelausstellfenster the maximum torque acts on the first pivot bearing of the fitting when the window is in the fully open position. The torque is due to the weight of the sash, which over the fourth pivot bearing with It acts on the lever arm via the support arm. In the fully open position, the distance between the first and fourth pivot bearing is maximum, so that due to the maximum lever length, the maximum torque is generated at the first pivot bearing (assuming a constant weight). Accordingly, the actuator must be designed so that the maximum torque acting on the first pivot bearing can be overcome with the window fully open. This maximum torque results from a maximum distance of the effective weight of the sash from the first pivot bearing. In other words, this maximum torque results from the product of the weight of the sash with the distance of the first of the fourth pivot bearing.

at closed window, however, is the distance of the fourth pivot bearing reduced by the first pivot bearing, so that at the same operating force now a large proportion of the operating force for example, for pressing the sash to the floor frame or to a window seal available stands. Such an operating force can be opened and closing the casement are minimized and there is a high proportion of the operating force to Pressing available. Thus, the fitting advantageously also for very heavy casements can be used and due to the small number of individual parts be produced inexpensively.

ever according to application, the distance of the first of the fourth However, pivot bearings are also chosen differently, for example at a substantially open window a minimum distance to provide between the first and fourth pivot bearing. In this case would be at constant operating force large proportion of the operating force for the movement of the casement is available stand. Therefore, such a design, for example, in Occurrence of high wind loads are used.

Of the Wing frame described above is not necessarily a closed Frame, but includes a filling element for a window and its fastening device for fastening the at least one fitting. Particularly preferred is the sash a window frame in the at least one glass pane as preferred Filling element is used. More preferably, the at least a glass pane attached to the casement, for example by gluing or screwing to the casement, in the case of screwing corresponding holes in the Glass pane are formed. The sash must be in this preferred case not fully formed as a frame but only at the bond areas. Especially the window can only have a fitting which is symmetrical in the x-direction attached to the sash is to the sash store or support in a predetermined manner at one point.

Preferably the window comprises at least two fittings, the at opposite or opposite vertical Pages of the sash are arranged. The vertical Sides of the sash are either the two opposing ones or opposite sides of the sash, extending essentially along the displacement direction V or the z 'direction, ie essentially along the vertical or, as stated above, at roof hatches substantially along the horizontal, extend. The vertical sides are spaced substantially along the horizontal Extension of the x-direction spaced, d. H. on the same vertical Position or height or with the same z-coordinate. hereby The weight of the window sash is over each the fourth swivel bearing added and over the fitting introduced into the floor frame. By providing two fittings on the window, the sash is in a predetermined manner stored or supported at two points, the fourth pivot bearings.

• – zumindest einen Zusatzbeschlag, wobei jeder Zusatzbeschlag einen Hebelarm aufweist, welcher

• - Is pivotally mounted by means of a second pivot bearing on the sash and slidably along the direction of displacement V on the sash and
• - Has an actuating device which is designed to actuate the additional fitting by applying a force to the actuating device.

The first pivot bearing of the additional fitting is pivotally mounted on the floor frame of the window, while the second pivot bearing is pivotally and slidably mounted on the sash. Since the lever arm is displaceable along the direction of displacement V on the casement, forces acting on the casement frame can only be transmitted to the lever arm via the second pivot bearing, in that only the force component directed perpendicular to the direction of displacement V can be transmitted. Therefore, in particular, the weight of the sash, which acts substantially along the direction of displacement V, when the sash is aligned parallel to a vertical building wall, substantially not by means of the additional fitting in the Transfer floor frame.

advantageously, perpendicular to the direction of displacement V acting tensile and compressive or tilting forces passing through on the sash acting wind loads and by tilting the sash arise, transferred to the lever arm of the additional fitting and lead to a relief of the fitting. This perpendicular to the direction of displacement V acting forces are on the one hand in the floor frame derived and on the other hand can these forces by applying a force to the actuator of the additional fitting be counteracted. For sashes that are against the Horizontal are inclined, as for windows parallel to Sloping ceilings, the weight of the sash at least partially over the second pivot bearing on the Transfer lever arm.

Especially the window can only have an additional fitting, which in the x direction is symmetrically attached to the sash to the sash to support at one point in the manner described above or to absorb the effective pressure and tilting forces.

Preferably the window comprises at least two additional fittings, at the opposite or opposite vertical Pages of the sash are arranged. The vertical Sides of the sash are either as described above the two opposite or opposite Side of the sash, which extends substantially along the displacement direction V and the z'-direction, ie substantially along the perpendicular or, as stated above, in roof hatches extend substantially along the horizontal. By providing of two additional fittings on the window becomes the sash advantageously supported in a predetermined manner at two points.

Further advantageously, over two Operating areas (that of the fitting and that of the additional fitting) Torques are applied to operate the (additional) fitting and to open or close the window.

Preferably is each support arm of the additional fitting by means of the fourth Swivel bearings on the sash pivot and along the displacement direction V on the casement displaced stored. Advantageously, the additional fitting is relative to Fitting displaceable, so that when you press the Fittings, d. H. when opening or closing the Window, no constraint occurs, d. H. no material deforming Stress on the fitting or sash.

Preferably is the actuator of the lever arm as substantially formed coaxially with the first pivot bearing arranged toothed segment. Advantageously, the radius, i. H. the distance between the individual teeth of the toothed segment and the first pivot bearing, constant, so that the acting around the first pivot bearing Torque constant regardless of the position of the lever arm is.

Preferably is the actuator of the lever arm with a engageable rack engaged. The rack is more preferably by means of the actuator (Crank, motor or the like) can be driven or actuated, in particular displaceable or movable back and forth.

Preferably is the rack without tooth base, d. H. the rack is ladder-like built with two longitudinal webs and a variety of transverse webs.

Preferably is the actuator of the lever arm with a operated coupling rod or coupling chain or an actuatable Coupling cable positively connected.

Preferably At least one fitting and at least one additional fitting are vertically one above the other arranged, wherein the respective actuating means the at least one fitting and the at least one additional fitting are positively connected with each other. Further preferably are the at least one fitting and the at least one additional fitting rigidly connected. Particularly preferred is the rigid Connection by means of a rigid rack or a rigid coupling rod. Due to the rigid coupling further preferably takes a synchronous Movement or actuation of the lever arms, so that advantageously tilting and constraining is avoided.

Preferably, the center of gravity of the sash during opening and closing moves substantially perpendicular to the plane defined by the gantry. This means that the center of gravity is shifted in particular horizontally, so that no lifting or lowering the center of gravity or the sash. Advantageously, it is thus not necessary to apply a force for lifting the casement by means of the actuating device. The dimensioning z. B. the engine can be correspondingly poor performance, so that advantageously costs for providing and operating the engine can be saved.

Preferably is the second pivot bearing vertically above the fourth pivot bearing arranged. Advantageously, thus the weight of the Wing frame through the fourth pivot bearing below the added second sliding pivot bearing. This results advantageously a mechanically stable arrangement with low Tipping moments, wherein the sash tends to above of the second pivot bearing of the first pivot bearing of the lever arm to tilt away.

Preferably corresponds to the distance between the two pivot bearings of the support arm essentially the distance between the third pivot bearing and the second pivot bearing of the lever arm. Advantageously, remains the sash when opening and closing aligned substantially parallel to the floor frame.

Preferably is the third pivot bearing essentially midway between the first pivot bearing and second pivot bearing arranged on the lever arm. Advantageously, the wing frame thereby substantially parallel to the frame when opening and closing offset, d.

Preferably is in the closed state of the window, the fourth pivot bearing arranged on the building side to the first pivot bearing and in the open state of the window is the fourth pivot bearing weather arranged to the first pivot bearing. Advantageously, by This arrangement of the necessary space can be minimized, since the fitting or the additional fitting in the closed state very close to or is moved into the floor frame inside and that of the first pivot bearing Seen from the building side area for the arrangement of the (additional) fitting is usable.

The required for pivoting the first pivot bearing torque results from the product of the weight of the sash and the distance of the first pivot bearing of the fourth pivot bearing. The torque required for pivoting can by an additional occurring wind load can be further increased. Of the Fitting is preferably configured so that in the closed State of the window or in almost closed state the distance of the first of the fourth pivot bearing is minimal, so that at predetermined torque of the actuating force of the first Swing bearings a large proportion of the torque for pressing of the sash to the frame or to the window seal is available. In addition, the fourth pivot bearing in the closed state of the window relative to the first pivot bearing positioned on the building side, acts in a closed position Condition or in almost closed state, the weight of the sash such that a torque to close the window is produced. In other words, it helps with the weight the sash produced torque advantageously at Pressing the sash to the floor frame or to the window seal. Advantageously, there are no additional Closures necessary, which the sash against Press the floor frame or the sash keep closed.

at suitable arrangement of at least one additional fitting in terms on the location of the center of mass of the sash and the at least one fitting occurs due to the weight the sash on the first pivot bearing of at least a fitting a first torque and due to the tipping force the sash on the first pivot bearing of at least an additional fitting on a second torque, wherein the first Torque is directed against the second torque.

The required for pivoting the sash torque can therefore by a preferably rigid connection of at least a fitting with the at least one additional fitting means the tilting forces acting on the sash frame be reduced. This reduces this by an actuator torque to be overcome. Especially preferred are Amount of first and second torque amount substantially equal, so that no resulting torque occurs. The actuator is thus advantageously free from the weight of the sash and must to Actuation of the fitting, d. H. to open and Close the window, only overcome the friction and wind load.

The Invention will now be described with reference to the accompanying drawings and an embodiment explained in more detail.

8th shows a side view of a fitting and an additional fitting another embodiment of a Parallelausstellfensters.

As in 1 is shown, a Parallelausstellfenster a floor frame 1 as well as a sash frame 2 on. The sash frame 2 is essentially parallel to the floor frame 1 displaced to an outside or weather side to open the Parallelausstellfenster.

To this displacement shift of the sash 2 opposite the pole frame 1 to enable, is the Parallelausstellfenster with four similar fittings 12 , where two fittings 12 serve as additional fittings, and preferably a pair of X-scissors 20 Mistake. The fittings 12 each have a lever arm 4 and a support arm 5 on. The lever arm 4 is about a first pivot bearing 8th with the cane frame 1 pivotally connected. Furthermore, one is with respect to the first pivot bearing 8th substantially opposite end of the lever arm 4 over a second pivot bearing 7 with the sash 2 pivotally connected. In addition, it is preferably located substantially in the middle of the lever arm 4 a third pivot bearing 10 on which a support arm 5 is articulated. The opposite end of the support arm 5 is about a fourth pivot bearing 9 with the sash 2 pivotally connected. To the displacement of the sash 2 opposite the pole frame 1 to enable, is also the second pivot bearing 7 the lever arm 4 on the sash 2 slidably disposed along a displacement direction V.

The fitting 12 is by applying a force to an actuator 14 operated so that the lever arm 4 around the first pivot bearing 8th pivoted. Thus, by pivoting about the first pivot bearing 8th such that the second pivot bearing 7 from the floor frame 1 is moved away, the window is opened and by pivoting the first pivot bearing 8th in such a direction that the second pivot bearing 7 to the floor frame 1 is moved, the window is closed. The weight of the sash 2 is doing of the fourth pivot bearing 9 over the support arm 5 and the third pivot bearing 10 in the lever arm 4 initiated. It should be noted that the second pivot bearing 7 the weight of the sash 2 can not pick up, because this is arranged to be displaceable.

That on the first pivot bearing 8th acting torque is from the horizontal distance of the first pivot bearing 8th to the fourth pivot bearing 9 dependent. In other words, the farther the fourth pivot bearing 9 in the horizontal direction (y-direction) of the first pivot bearing 8th is removed, the greater the torque, due to the weight of the sash 2 is produced.

As further in the 2 and 3 is shown, is the distance of the first pivot bearing 8th from the fourth pivot bearing 9 when the window is fully open, so that in this position of the window a maximum torque on the first pivot bearing 8th acts. Furthermore acts at the in

2 shown full opening position of the window and the in 3 shown partial opening position of the window by the weight of the window sash 2 generated torque in a clockwise direction about the first pivot bearing 8th ,

In contrast, acts as in 4 shown the torque in the closed position of the sash 2 in the opposite direction, ie in the counterclockwise direction, because the fourth pivot bearing 9 in this position on the building side before the first pivot bearing 8th is arranged. The weight of the sash 2 applies a left-handed torque on the first pivot bearing 8th out. Thus, the weight of the sash supports 2 the pressing of the sash 2 on the floor frame 1 ,

To operate the fitting 12 or for pivoting the lever arm 4 around the first pivot bearing 8th a torque must be exercised. This torque can, for example via a crank, another (not shown) lever or a stepper motor (not shown), a transmission, or the like via the actuator 14 be exercised. Preferably, the lever arm 4 but substantially coaxial with the first pivot bearing 8th with a toothed segment 6 or a ring gear (not shown) as a preferred actuator 14 provided, the / with a rack 3 is engaged. This rack 3 is preferably substantially along the vertical direction (z-direction) on the floor frame 1 slidably arranged. By moving the rack vertically 3 can the toothed segment 6 be actuated to a pivoting force about the first pivot bearing 8th on the lever arm 4 exercise. The window can be adjusted by moving the rack vertically 3 be opened and closed.

The rack is preferably designed as a rack without tooth base. In other words, the rack has a ladder-like shape with two (not shown) substantially vertically arranged longitudinal struts and a plurality of transverse webs 32 which act as teeth for engaging the sector gear 6 Act. This rack 3 can be displaced manually or via a pneumatic or hydraulic cylinder or an equivalent force application device.

The X-scissors 20 have a pair of scissor arms 22 on, by means of scissor joints 24 each on the floor frame 1 and the sash frame 2 are mounted. Each one is one of the scissor joints 24 from each scissor arm 22 in addition to one from the floor frame 1 or the sash 2 slidably mounted to a relative movement of the sash 2 opposite the pole frame 1 to enable.

Although in the present embodiment, the fitting 12 is arranged such that the first pivot bearing 8th with the toothed segment 6 and the rack 3 on the floor frame 1 is mounted and the second pivot bearing 7 and the fourth pivot bearing 9 on the sash 2 mounted, the fitting can also be mounted vice versa, so that the first pivot bearing 8th with the rack 3 on the sash 2 is mounted and the second pivot bearing 7 and the fourth pivot bearing 9 on the floor frame 1 to be assembled. Furthermore, it is not necessary, two pairs of such fittings 12 to arrange on a Parallelausstellfenster. The Parallelausstellfenster can also only one or preferably two such fittings, preferably on the vertical sides 16a . 16b of the window arranged. When placing only one such fitting 12 Yet another fitting or the like is required to support the weight force at least two points. For this example, an X-scissors, Y-scissors or the like is suitable.

Evidently, the X-scissors are 20 the embodiment shown only optional to arrange for large windows, while smaller windows on X-scissors for additional guidance of the window can be dispensed with.

That in the 5 in a side view shown Parallelausstellfenster includes a fitting 12 and an additional fitting 12b moving in the z-direction from the fitting 12 is arranged.

A lever arm 4 of the fitting 12 is by means of a first pivot bearing 8th on the floor frame 1 pivoted. Next is the lever arm 4 by means of a second pivot bearing 7 on the sash 2 pivotable and along a direction of displacement V on the sash 1 slidably mounted. An actuating device 14 the lever arm 4 has substantially coaxial, ie with a constant distance, to the first pivot bearing 8th arranged tooth segments 6 on that in the rack 3 intervention. This is the first pivot bearing 8th acting torque advantageously independent of the position of the lever arm 4 constant. By an actuator (not shown), such as a motor, is by means of the rack 3 a force on the actuator 14 can be applied to the fitting 12 to press.

A support arm 5 of the fitting is by means of a third pivot bearing 10 on the lever arm 4 pivoted. Next is the support arm 5 by means of a fourth pivot bearing 9 on the sash 1 pivoted. The weight force of the casement, which acts counter to the z-direction 1 is by means of the support arm 5 on the lever arm 4 transfer. Here is the second pivot bearing 7 spaced in the z-direction from, that is, above the fourth pivot bearing 9 arranged.

The distance between the two pivot bearings 9 . 10 of the support arm 5 corresponds essentially to the distance between the third pivot bearing 10 and the second pivot bearing 7 the lever arm 4 , The third pivot bearing 10 is substantially centered between the first pivot bearing 8th and second pivot bearing 7 on the lever arm 4 arranged.

The lever arm 4 and the sash frame 2 are displaceable relative to each other along the shift direction V (in this case substantially along the z-direction). The weight of the sash 2 is therefore not on the second pivot bearing 7 on the lever arm 4 transfer. However, the sash is 2 stored unstable, ie below the center of mass S of the sash. Therefore, tilting forces occur perpendicular to the shift direction V. These tilting forces cause due to the formation of the support arm 5 that the Flügelrah men 1 above the fourth pivot bearing 9 a force substantially contrary to the y-direction experiences, so tilted away from the building.

To counteract this tilting, the window comprises an additional fitting 12b , which in z-direction from the fitting 12 spaced, ie above it, is arranged. It is understood that the additional fitting 12b also below the fitting 12 can be arranged so that the fitting 12 from the additional fitting 12b spaced apart in the z-direction.

The additional fitting 12b has a lever arm 4b on, which by means of a first pivot bearing 8b on the floor frame 1 the window is pivotally mounted and by means of a second pivot bearing 7b on the sash 2 pivotable and along a direction of displacement V on the sash 1 is slidably mounted. An actuating device 14b the lever arm 4b the additional fitting 12b points, analogous to the fitting 12 , substantially coaxial with the first pivot bearing 8b arranged tooth segments 6b on that in the rack 3b intervention. This is the first pivot bearing 8b acting torque advantageously independent of the position of the lever arm 4b constant. The rack 3b is with the rack 3 , which with the fitting 12 engaged, rigidly connected, so that both racks 3 . 3b can be actuated by the actuator.

With suitable dimensioning and arrangement of the casement 2 , the fitting 12 and the additional fitting 12b occurs due to the weight of the sash 2 at the first pivot bearing 8th of the fitting 12 a first torque and due to the tilting force of the sash 2 at the first pivot bearing 8b of additional fitting 12b a second torque, wherein the first torque is directed against the second torque. Preferably, the first and second torque are substantially equal in magnitude. Due to the intervention of the controls 14 . 14b of the fitting 12 or additional fitting 12b with the racks 3 and 3b , the racks become 3 and 3b subjected to opposite forces. Because the racks 3 and 3b preferably rigidly coupled, cancel the opposing forces at least partially, so that a reduced or preferably no resultant force on the actuator of the racks 3 . 3b is transmitted. Since the actuator is thus advantageously free of the weight of the sash, the actuator may have a correspondingly low performance, ie a performance that only overcomes friction and wind load.

It is understood that 5 just a top view on one of the vertical sides 16a . 16b shows and that another fitting 12 and additional fittings 12b on the opposite vertical side 16a . 16b of the sash 2 are arranged.

The 6 . 7 and 8th show to the in 5 embodiments shown modified embodiments. Therefore, only the features different from those in FIG 5 shown features.

6 shows a side view of a fitting 12 and an additional fitting 12b an embodiment of a Parallelausstellfensters, wherein - in contrast to in 5 shown embodiment - the additional fitting 12b below the fitting 12 is arranged so that the fitting 12 from the additional fitting 12b spaced in the z-direction.

7 shows a side view of a fitting 12 and an additional fitting 12b an embodiment of a Parallelausstellfensters, wherein - in contrast to in 5 shown embodiment - the additional fitting 12b in addition a support arm 5b having.

The support arm 5b of additional fitting 12b is by means of a third pivot bearing 10b on the lever arm 4b pivoted. In addition, the support arm 5b by means of a fourth pivot bearing 9b on the sash 1 pivoted. The weight force of the casement, which acts counter to the z-direction 1 is at least partially by means of the support arm 5b of additional fitting 12b on the lever arm 4b transfer. Here is the second pivot bearing 7b spaced in the z-direction from, that is, above the fourth pivot bearing 9b arranged. The distance between the two pivot bearings 9b . 10b of the support arm 5b corresponds essentially to the distance between the third pivot bearing 10b and the second pivot bearing 7b the lever arm 4b the additional fitting 12b , The third pivot bearing 10b is substantially centered between the first pivot bearing 8b and second pivot bearing 7b on the lever arm 4b the additional fitting 12b arranged.

8th shows a side view of a fitting 12 and an additional fitting 12b an embodiment of a Parallelausstellfensters, wherein - in contrast to in 7 shown embodiment - the fourth pivot bearing 9b the additional fitting 12b is formed displaceable along a displacement direction V. Therefore, the weight of the sash 2 not through the additional fitting 12b be recorded. Advantageously occur in this embodiment when operating the fitting 12 , ie when opening or closing the window, no constraints on.

Although the present embodiments are described with respect to a Parallelausstellfensters, the fitting 12 and / or the additional fitting 12b be used for other types of windows, for example, windows that are not parallel to the vertical, but at a certain angle α issued to it. In this case, the angle α is preferably in a range between about 0 and about 90 degrees, more preferably between about 0 and about 75 degrees, more preferably between about 0 and about 45 degrees, even more preferably between about 0 and about 25 degrees, in particular between about 0 and about 15 degrees. The second pivot bearing 7 and the fourth pivot bearing 9 then are not vertically aligned with the sash 2 arranged, but for example offset horizontally. Another way to create a window that is to be issued at an angle, is the distance of the third pivot bearing 10 and the fourth pivot bearing 9 of the support arm 5 different from the distance of the third pivot bearing 10 from the second pivot bearing 7 to design.
