Description

The present invention relates to a fitting arrangement for a window, a door or the like for mounting a sash on a frame, which can be rotated about an axis of rotation and can be tilted about a tilt axis, and a window, a door or the like with such a fitting arrangement.

Such fitting arrangements make it possible to open the sash in at least two different ways, namely to tilt-open or to open-turn. Typically, the axis of rotation and the tilt axis are oriented perpendicular to one another, the axis of rotation generally being oriented vertically and the tilting axis being oriented horizontally. In principle, however, different orientations are also possible. In addition, the two types of opening can also differ with regard to the possible opening width. For example, it can be provided that rotary opening is possible up to an angle of at least 90 °, preferably significantly beyond, in order to fully open the window or door, whereas tilt opening to a significantly smaller opening angle, for example at most about 20 °, so that, for example, to ventilate the wing, only a gap is tilted open.

The fitting arrangement can typically comprise a faceplate, a scissor arm and a scissor link, the faceplate being designed to be attached to a side of the sash remote from the tilt axis; wherein the scissor arm is designed to be mounted on the frame with one end on the frame side, in particular via a scissor bearing, so as to be rotatable about the axis of rotation, and with one end on the wing side is articulated on the faceplate; and wherein the scissor link is articulated with an arm-side end to a fork section of the scissor arm and is articulated with a wing-side end to the faceplate.

The pivotable and tilt-openable mounting of the respective sash on the respective frame thus takes place at least in part via the mentioned elements of the fitting arrangement. The faceplate to be fastened to the wing serves, among other things, to provide reliable coupling options for the scissor arm and the scissor link on the wing. The scissor arm is essentially used to connect the sash to the frame. For this purpose, it is hinged to the faceplate with its wing-side end and can be supported on the frame with its frame-side end. In order to enable the sash to be opened to rotate, this mounting on the frame side is preferably such that the scissor arm is rotatable about the axis of rotation. For this purpose, the scissor arm can be connected or connectable to a scissor bearing attached or to be attached to the frame. By connecting the sash to the frame, the scissor arm contributes significantly to the mounting of the sash on the frame. In particular, the scissor arm supports the wing in its rotatably open state against the force of gravity acting on the wing. The scissor arm is usually arranged on an upper side of the wing, which in this respect is carried by the scissor arm.

When the sash is tilted open, its side remote from the tilt axis is moved away from the frame, so that the scissor arm connected to the faceplate provided there swings out and bridges the resulting tilt opening gap at an angle. Since the distance between the point at which the scissor arm is hinged to the faceplate in the closed state and the point at which the scissor arm is rotatably mounted on the frame side changes, the articulation of the scissor arm to the faceplate changes typically not stationary, but to a limited extent along the faceplate Adjustable dimensions. Limiting the displaceability (for example, from the length of an elongated hole formed in the faceplate, into which a pin provided on the scissor arm engages) can directly limit the width of the tilt opening.

The scissor link creates an additional connection between the scissor arm and the faceplate, with which it is connected in an articulated manner. In the closed and rotatably open state of the sash, it is usually aligned parallel to the scissor arm and the faceplate. However, if the wing is tilted open and the scissor arm swings out in relation to the faceplate, the scissor arm is consequently swiveled out in a similar manner, so that it bridges the opening angle between the scissor arm and the faceplate in particular. The cross connection formed in this way by the scissor link between the scissor arm and the faceplate can advantageously contribute to the stability of the mounting of the sash on the frame. However, this also changes the distance between the respective points at which the scissor link is hinged to the scissor arm or the faceplate when the sash is closed, so that the scissor arm is often not articulated to a fixed point on the faceplate but a certain variability is provided.

The faceplate, the scissor arm and the scissor link can each have at least essentially a strip shape, that is to say an elongated, flat shape. The named frame-side, wing-side or arm-side ends can in particular be formed by respective end regions of the longitudinal extension of the respective strip shape.

In a fitting arrangement of the type described, it is important that its length, which effectively contributes to supporting the sash, is set correctly. This length is determined in particular by the scissor arm connecting the sash to the frame Are defined. In particular, if the scissor arm is arranged as usual on an upper side of the wing, at least when the wing is open in rotation, a substantial part of the possibly considerable weight of the wing is carried off via the scissor arm. In this rotatably open state, due to the force of gravity of the wing, forces in particular act on the scissor arm in the direction of a lowering of the wing and thus in the direction of an extension of the scissor arm. If, on the other hand, the sash is closed or tilted open (with a tilt axis typically provided on a lower side of the sash), the sash can be supported on the frame, so that a correct alignment of the sash can already be guaranteed.

If the fitting arrangement, in particular the mentioned length of the scissor arm, which effectively contributes to the bearing, is incorrectly set, this consequently has an effect in particular on the alignment of the sash in the rotationally open state. The wing is then, for example, lowered or raised in relation to a correct alignment. If such a misaligned sash is then closed in rotation, it can happen that the sash does not pivot flush into the frame, but runs against the frame on one side. It is true that the wing can possibly be brought into the closed position by this opening, in which it is then correctly aligned with the frame. However, since the cause of the misalignment is not eliminated by this, the correction is not permanent, but rather the sash re-aligns itself incorrectly as a result of the wrong length of the scissor arm the next time the pivot is opened and thus runs against the frame again when the pivot is closed. However, repeated opening can lead to increased wear, both on the sash and frame and, due to the resulting irregular loading, on the fitting arrangement itself. In addition, the run-up can be audible or otherwise perceptible as faulty and disruptive.

The misalignment of the sash does not have to be based on a fitting arrangement that was set incorrectly from the start, for example during assembly, but can only arise over time due to the dead weight of the sash. This can in particular lead to the fact that the wing "settles" as a result of its own slight deformations and / or as a result of slight deformations in the mounting, ie lowers a little, so that an adjustment of the fitting arrangement is necessary to compensate for the misalignment.

Ideally, the fitting arrangement is set in such a way that the sash is held in the correct orientation when it is pivoted from the closed position in which it is received flush in the frame and is advantageously already held and supported in the correct orientation by the frame itself, even if the frame is no longer supported by opening the door. In order to compensate for this lack of support in the rotatably open state, the fitting arrangement must leave little play in the sash, particularly in the direction of lowering, so that the scissor arm between the sash and the frame preferably produces a rather tight connection. In the tilt-open state, on the other hand, the scissor arm serves less to absorb weight forces than to limit the width of the tilt opening, so that the fitting arrangement can be set comparatively more loosely EP 1 710 379 A1 discloses an example of a bracket assembly.

It is an object of the invention to provide an improved fitting arrangement or a window, a door or the like with an improved fitting arrangement which preferably enables a simple, in particular automatic, compensation of misalignments of the sash and a reliable, in particular position-dependently adapted, mounting of the sash supported.

The object is achieved by a fitting arrangement having the features of claim 1.

The solution is based in particular on the fact that the distance between the fork section and the wing-side end of the scissor arm is variable. In particular for this purpose, the scissor arm is designed in at least two parts and comprises a support member on which the frame-side end of the scissor arm is formed, and a separate pivot member on which the wing-side end of the scissor arm is formed, the support member and the pivot member relative to one another are displaceable, in particular along a longitudinal axis of the scissor arm.

The support member and the pivot member can be displaced relative to one another in such a way that the distance between the fork section and the wing-side end of the scissor arm is variable. In other words, the support member is displaced relative to the pivot member in the area between the fork section on which the scissor link is hinged and the wing-side end of the scissor arm on which the scissor arm is hinged to the faceplate.

With such a design, the pivoting member can be made comparatively short, while the support member extends over the major part of the length of the scissor arm. The area between the fork section and the frame-side end of the scissor arm preferably comprises more than half, in particular more than two thirds, particularly preferably more than three quarters, of the length of the scissor arm.

By providing the displaceability between the fork section and the wing-side end of the scissor arm, the area between the fork section and the frame-side end of the scissor arm can be essentially rigid, i.e. in particular with a constant length, which advantageously results in reliable storage of the wing.

The support member and the pivot member of the scissor arm can be coupled directly to one another or else via one or more further elements so that they can be displaced relative to one another. Since the frame-side end of the scissor arm is formed on the support member and the wing-side end is on the pivot member, an offset of the support member relative to the pivot member leads to a corresponding change in the distance between the frame-side and the wing-side end of the scissor arm and thus to a change in length of the Scissor arm. The displaceability of the support member relative to the pivot member can be limited, so that the length of the scissor arm can change, in particular freely, within a defined length range.

This length variability, which is free within the defined length range, can be used in particular for the tilt opening of the sash, in which the scissor arm connecting the sash to the frame swings out and bridges the opening gap at an angle. Because the scissor arm can be lengthened relative to the pivot member by moving the support member, the point at which the scissor arm is hinged with its wing-side end to the faceplate does not need to be designed to be variable in order to enable the tilt opening. The maximum width of the tilt opening can be determined by the amount of free extensibility of the scissor arm, which is predetermined by the amount of displaceability of the support member relative to the pivot member.

The ability to freely change the length of the scissor arm thus enables an advantageous embodiment in which it is provided that the wing-side end of the scissor arm is articulated to a fixed pivot point of the faceplate. This has the advantage that there is no need to provide a structurally more complex variable articulation point for the scissor arm on the faceplate. In addition, a fixed pivot point can basically be made more stable.

Alternatively, preferably in addition, the scissor link can also be articulated with its wing-side end to a fixed pivot point of the faceplate. Because also with the scissor link there is basically the corresponding problem that a changing distance between the scissor arm and the faceplate has to be bridged when the scissor arm and the scissor link are opened due to a tilt opening of the sash. For improved stability, this problem is then nevertheless not solved by a variable articulation point of the scissor link on the faceplate, but rather a fixed pivot point is provided. Because fixed pivot points for the articulation of the scissor arm and / or the scissor link on the faceplate allow a simplified design of the faceplate and a particularly reliable coupling of the scissor arm and / or the scissor link with the faceplate.

According to the invention, the arm-side end of the scissors link is articulated to a fork point of the scissor arm that is variable within the fork section, in particular along the longitudinal axis of the scissor arm. In particular, if the wing-side end of the scissor link is hinged to a fixed pivot point of the faceplate, a fork point that is variable within the fork section enables the scissor arm to always connect the fork section of the stay arm to the faceplate regardless of the width of the tilt opening, without that the scissor link must be variable in length for this.

According to an advantageous development, the scissor arm and the scissor link cooperate in such a way that, depending on the respective relative angular alignment of the scissor arm and the scissor link, the variability of the fork point within the fork section is limited in the direction of the wing-side end of the scissor arm. In other words, the position of the fork point cannot always be freely taken within the entire fork section, it is influenced by how the scissor link is oriented relative to the scissor arm.

The respective position of the fork point within the fork section is preferably clearly predetermined by the respective angular alignment of the scissor link relative to the scissor arm. However, it can also be the case that the variability of the fork point is only restricted to a degree that is dependent on the respective angular orientation, and specifically preferably at least on one side in the direction of the wing-side end of the scissor arm. Then the fork point within the fork section is not always variable over its entire extent, but at least in the direction of the wing-side end of the scissor arm only up to a respective limit position, which depends on the respective angular orientation of the scissor arm relative to the scissor arm.

In particular, the variability of the fork point within the fork section can be more limited in the direction of the wing-side end of the scissor arm, the less the alignment of the scissor link and the alignment of the scissor arm differ from one another. When the wing is closed or pivoted open, when the scissor arm and the scissor link are generally aligned at least substantially parallel to one another, the fork point is thus kept within the fork section particularly far from the wing-side end of the scissor arm, whereas the fork point is when the tilt opening is the scissor arm and the scissor link can shear open to move within the fork section on the wing-side end of the scissor arm.

Correspondingly, in an embodiment in which the respective position of the fork point within the fork section is clearly specified by the respective angular alignment of the scissor link relative to the scissor arm, it is correspondingly preferred that the fork point at each other parallel alignment of the scissor arm and the scissor link is further away from the wing-side end of the scissor arm than with an angled alignment of the scissor arm and the scissor link.

By means of such an embodiment it can be achieved that the fork point is automatically offset within the fork section in the direction away from the wing-side end of the scissor arm when the sash is tilted. This displacement of the fork point within the fork section can, in particular if the scissor link is hinged with its wing-side end to a fixed pivot point of the faceplate, to a reverse displacement of the support member of the scissor arm in the direction of its wing-side end, which then corresponds to a shortening of the scissor arm. Consequently, when the wing is tilted, the length of the scissor arm is always shortened by a certain amount, which is predetermined by the angular dependency of the position of the fork point within the fork section and for example between 1 and 10 mm, in particular between 2 and 8 mm, preferably about 4 mm can be.

The advantage of such an automatic shortening of the length of the scissor arm when tilt closing is that the shortening tightens the scissor arm, so to speak, and thus prepares it for a pivot opening of the sash, in which the scissor arm bears a substantial part of the weight of the sash. In particular, the tightening shortening of the scissor arm can serve at least essentially to compensate for possible play in the fitting arrangement. Conversely, when the sash is tilted open, the length of the scissor arm can automatically lengthen again in a similar manner, in particular by the same amount, so that the scissor arm is so to speak relaxed and thus relieved. This is possible because the load on the scissor arm is significantly lower in the tilt-open state, as the sash can then essentially be supported by the frame and correctly aligned. so that the scissor arm, instead of supporting the wing, can primarily serve to limit the tilt.

According to an advantageous embodiment, the scissor arm has a guide slot on which a guide section of the scissor link is guided as a function of the relative angular alignment of the scissor arm and the scissor link. The embodiment can also be designed exactly the other way round, so that the scissor link has a guide slot on which a guide section of the scissor arm is guided depending on the relative angular alignment of the scissor arm and the scissor link. It is precisely through the interaction of the respective guide link with the respective guide section that the above-described dependency of the position of the fork point within the fork section on the relative angular alignment of the scissor arm and the scissor link can be realized.

In a further advantageous embodiment, it is provided that the pivotability of the scissor link is limited to a maximum pivoted-out orientation by a stop formed in particular on the scissor arm or on the faceplate. In particular, the scissor link strikes the stop when it assumes the maximum pivoted orientation relative to the scissor arm, so that it cannot be pivoted beyond that. Such a limitation increases the overall stability of the fitting arrangement in the tilt-open state of the sash, since this creates an, in particular additional, definition of how far the sash can be tilt-open.

According to a preferred embodiment, the scissor arm further comprises an intermediate member which is coupled to the support member and to the pivot member and which can be displaced relative to the pivot member, in particular along the longitudinal axis of the scissor arm, the fork section on the intermediate member is trained. In this embodiment, the scissor arm is therefore not only designed in two parts, but at least in three parts and comprises the pivot member, the intermediate member and the support member. The intermediate member coupled to the pivot member and the support member can in particular serve to connect the pivot member to the support member so that the support member is only indirectly connected to the pivot member. In addition, since the fork section to which the scissor link is articulated on the scissor arm is formed on the intermediate link, the scissors link is also coupled to the intermediate link.

In this way, the functions of the scissor arm can advantageously be divided between its various parts. The support member can in particular extend over a predominant part of the length of the scissor arm and thus serve to bridge the distance between the fork section and the wing-side ends of the fitting arrangement on the one hand and the frame-side end mounted on the frame on the other. The pivot member can essentially serve to articulate the scissor arm to the faceplate and also provide guide means for moving the intermediate member or the support member along the longitudinal axis of the scissor arm. And the scissors arm creates a cross connection between the fork section and the wing for additional stabilization of the arrangement. The named intermediate member can be viewed as the central link between these movable elements of the fitting arrangement.

Basically, the intermediate member and the support member can be firmly connected to each other so that they can be moved together relative to the pivot member, so that the length of the scissor arm for the tilt opening and the thereby increasing distance between the sash and the frame can automatically increase Tilt-closing can decrease again accordingly.

According to an advantageous embodiment, however, it is provided that the support member is displaceable relative to the intermediate member, in particular along the named longitudinal axis of the scissor arm, locking means being provided between the support member and the intermediate member in order to determine a relative position of the support member and the intermediate member. In this embodiment, in addition to the displaceability of the support member or the intermediate member relative to the pivot member, there is also provision for the support member and the intermediate member to be displaceable relative to one another. In contrast to the displaceability relative to the pivot member described above, this displaceability is not fundamentally free, but the support member and the intermediate member can be fixed in a respective position relative to one another by locking means. In order to move the support member relative to the intermediate member, the locking means must therefore first be released, whereby such release can basically be done manually, but also automatically, e.g. depending on a respective position, alignment or direction of displacement.

The displaceability between the support member and the intermediate member can thus be used for a basic length adjustment or adjustment of the scissor arm, whereas the displaceability of the support member or the intermediate member relative to the pivot member only serves to reduce the due to the pivoting in the tilt-open state compared to the closed or to enable the swivel arm required increase in length in the pivoted open state. It is particularly advantageous to provide the basic length adjustability in the area between the fork section and the wing-side end of the scissor arm, since the locking means can then be actuated depending on the orientation, for example by interacting with the pivoting member or the scissor link, as will be explained below.

According to an advantageous further development, the locking means are pretensioned in a locking state, that is to say determining the relative position of the support member and the intermediate member. Thus, the support member and the intermediate member form a unit of defined length as long as the locking means are not released against the bias. In this way, the scissor arm can perform the usual function of supporting the wing or limiting its tilt opening. An offset of the support member relative to the intermediate member is namely not necessary for this usual function and could even be a hindrance. The displacement of the support member relative to the intermediate member is at least essentially only necessary if the length of the scissor arm is incorrectly set and therefore has to be corrected. It is therefore advantageous if the locking means are normally kept in the locking state by the bias.

According to a further advantageous development, it is provided that the blocking means block a displacement of the support member relative to the intermediate member in one direction, in particular in the direction of increasing the distance between the fork section and the frame-side end of the scissor arm, and in a direction opposite to this. Thus, the locking means determine the relative position of the support member and the intermediate member. If, however, the support member and the intermediate member are acted upon for displacement in a specific direction relative to one another, this displacement can be permitted by the locking means differently than in the case of an opposite action. In other words, the locking means are released automatically in a defined displacement direction. In this respect, the locking means can be designed as latching means in such an embodiment.

It is particularly advantageous if the locking means reliably counteract an increase in the distance between the fork section and the frame-side end of the scissor arm, that is, an extension of the scissor arm. Because in this direction the scissor arm is in particular loaded when the sash is open. But then the scissor arm should reliably carry the wing, which is why an extension of the scissor arm must be prevented.

On the other hand, it can be useful if it is possible to offset the support member relative to the intermediate member in the opposite direction, that is to say in the direction of shortening the scissor arm. This is because if the sash is misaligned, in particular has lowered as a result of gravity, it may run against the frame when it is turned and thus lifted into the correct alignment. This then has the effect of acting on the scissor arm in the direction of shortening. Since such a shortening is permitted by the locking means in this embodiment, the support member and the intermediate member are correspondingly offset relative to one another as a result of the impact and are fixed again in the new relative position by the locking means. In this way, the length of the scissor arm can be automatically adjusted to compensate for the misalignment of the wing.

According to a further advantageous embodiment, the locking means are designed to interact in particular with the pivot member in such a way that, depending on the relative position of the pivot member and the intermediate member, in particular when a maximum distance is reached between the fork section and the wing-side end of the scissor arm, they merge into one Displacement of the support member can be adjusted relative to the intermediate member releasing state. In other words, the locking means are automatically released depending on the relative position of the pivot member and the intermediate member. In particular, the locking means are automatically released when the fork section reaches a maximum distance from the wing-side end of the scissor arm. This is at least essentially the case when the intermediate member on which the fork section is formed is at a maximum relative to the pivot member which has the wing-side end of the scissor arm is offset in the direction of the frame-side end of the scissor arm. This state is particularly the case when the sash is fully tilted and the scissor arm must therefore bridge the greatest distance between the sash and the frame.

While the locking means must hold the support member and the intermediate member reliably in their respective relative position when the sash is open to rotate, so that the sash is reliably supported, they can be safely released when the sash is tilted, since the sash is primarily not supported by the scissor arm, but by the frame becomes. In contrast to the twist-open state, in which advantageously only a shortening of the length of the scissor arm is permitted, the tilt-open state is therefore also suitable for enabling automatic length adjustment of the scissor arm in the direction of an extension.

A scissor arm that is set too short can be present immediately after installation, for example. In the closed state of the sash, in which the sash is held correctly aligned by the frame, the insufficient length then leads to an impact on the scissor arm in the direction of an extension, which, however, due to the locking means that determine the relative position of the support member and the intermediate member, can be locked. After assembly, however, the sash only needs to be tilted open once in order to set the length correctly. Because in the tilt-open state, the locking means can automatically release in this embodiment, so that the sash resting on the frame can align itself correctly and the length of the scissor arm can thus automatically extend to the dimension corresponding to the correct alignment. With tilt locking, the release of the locking means is then canceled again, so that the correct length is then maintained.

In such an embodiment, to correct a misalignment of the sash, the length of the scissor arm can automatically be suitably lengthened by tilting opening and closing and automatically suitably shortened by turning opening and closing. In this way, the manual length adjustment of the scissor arm, which is usually required during assembly, can also be omitted entirely. Since the locking means always permit a shortening of a scissor arm that is too long and, in the tilt-open state, an extension of a scissor arm that is too long is made possible, the wing only needs to be tilted open and closed once to adjust the length of the scissor arm after assembly. A subsequent lowering of the sash over time (so-called "setting") is also automatically compensated for each time the sash is turned, that is, essentially through normal use.

According to a preferred embodiment, the locking means are formed as interlocking, in particular asymmetrical, toothings formed on the one hand on the support member and on the other hand on the intermediate member. By such toothing, the locking means can be designed in a structurally simple manner, in particular also in the manner of latching means. In order to fix the relative position of the support member and the intermediate member, the toothings are then brought into engagement with one another, in particular by the pretensioning mentioned. The tooth flanks can be designed so asymmetrically in relation to the possible displacement directions of the support member and the intermediate member relative to each other that the teeth automatically at least temporarily disengage when moved in one direction and thus allow displacement, in the other direction remain engaged and thus block the move.

The object of the invention is also achieved by a window, a door or the like with a fitting arrangement according to one of the embodiments described above.

Figures 5 to 8

show an embodiment of the fitting arrangement in each case in a position corresponding to a closed or rotated open state of the sash and in a position corresponding to a tilt-open state of the sash.

In the Fig. 1 The illustrated embodiment of a fitting arrangement 11 comprises a faceplate 13, a scissor arm 15 (cf. Fig. 2 and 5 ) and a scissor link 17. The fitting arrangement 11 is not shown in full. In particular, only a central area of the faceplate 13 is shown, which is essentially delimited by the two fixed pivot points 19, 19 ′ at which the scissor arm 15 or the scissor link 17 is hinged to the faceplate 13 is. Furthermore, the scissor arm 15 comprises a support member 21, a pivot member 23 and an intermediate member 25, of which in FIG Fig. 1 only the pivot member 23 and the intermediate member 25 are shown. The support member 21 is in the other figures, in particular in Fig. 5 complete, shown.

The faceplate 13 is designed to be attached to the side of a sash, not shown, of a window, a door or the like, which is opposite a tilt axis for tilt opening. After the fastening, the faceplate 13 is then arranged in a fixed position relative to the sash, but when the sash is tilted open, it can move away together with the sash parallel to the frame, also not shown (in the Fig. 1 and 5 to 8 in the display level down).

The scissor arm 15 is used to connect the faceplate 13 to a frame-side scissor bearing 26 (cf. Fig. 5 ), via which the scissor arm 15 is rotatably mounted on the frame about an axis of rotation D for opening the sash in rotation. In this way, the scissor arm 15 can support the wing so that part of the weight of the wing is carried off by the scissor arm 15 when the wing is rotatably open. For this purpose, the scissor arm 15 is provided with an end 27 on the frame side (cf. Fig. 5 ), which is formed on the support member 21, attached to the scissor bearing 26 and hinged with a wing-side end 29, which is formed on the pivot member 23, to the fixed pivot point 19 on the faceplate 13.

In the closed or rotatably open state of the wing, the scissor arm 15, as in particular in FIG Fig. 1a ) and 5a ) shown, aligned parallel to the faceplate 13. When the sash is tilted open, the faceplate 13 is offset in parallel, so that the stay arm 15 connecting the fixed pivot point 19 on the faceplate 13 to the stay bearing 26, as in particular in FIG Figure 1b ) and 5b ) swings out and the distance to be bridged by the scissor arm 15 is thus increased.

In order to enable the increase in length of the scissor arm 15, which is therefore necessary for tilt opening, the support member 21 can be displaced relative to the pivot member 23 along the longitudinal axis L of the scissor arm 15 so that the length of the scissor arm 15 can be freely changed at least within a certain range. In this way, when the sash is tilted open, the length of the scissor arm 15 is automatically lengthened to the extent required for this and is correspondingly shortened again when the sash is tilted closed.

Specifically, this is in Fig. 1 Support member 21, not shown, is coupled to the intermediate member 25, which in turn can be displaced relative to the pivot member 23 along the longitudinal axis L. The named change in length to enable tilting opening and closing thus results at least essentially from the displaceability of the intermediate member 25 relative to the pivotable pivot member 23 which is articulated at the fixed pivot point 19.

The pivot member 23 and the intermediate member 25 are connected via a pin 31 formed on the frame side on the pivot member 23, which engages in an elongated hole 33 formed on the intermediate member 25 and extending along the longitudinal axis L and within the elongated hole 33 along the longitudinal axis L of the scissor arm 15 is movable. In addition, the intermediate member 25 is at least partially flanked on both narrow sides of its strip shape by wall sections 34 of the pivot member 23, which in particular ensure that the intermediate member 25 and the intermediate member 25 are always aligned parallel to one another.

The interaction of the pin 31 with the elongated hole 33 defines the relative displaceability of the pivot member 23 and the intermediate member 25. The degree of displaceability is limited by the length of the elongated hole 33, which is selected so that the change in length required for the tilt opening or closing of the scissor arm 15 is made possible, as well as the comparison of the Fig. 1a) and 1b ) shows, in which the pin 31 is arranged at a respective other end of the elongated hole 33. Thus, the maximum width of the tilt opening can be determined (among other things) by the length of the elongated hole 33.

The scissors link 17 is hinged with a wing-side end 35 to the further fixed pivot point 19 ′ on the faceplate 13 and with the opposite end 37 on the arm side is hinged to a fork section 39 of the scissor arm 15. The fork section 39 is defined by a further elongated hole 41 which is formed on the frame side in the intermediate member 25 (cf. Fig. 2 ) and in which a pin 43 provided on the arm-side end 37 of the scissor link 17 engages. The respective position of the pin 43 within the elongated hole 41 defines a respective fork point 45, which is thus basically variable within the fork section 39 defined by the elongated hole 41.

However, the pin 43 cannot move freely within the elongated hole 41. Rather, its position and thus the position of the fork point 45 within the fork section 39 depends on the respective angular alignment of the scissors arm 17 relative to the intermediate member 25. Because on the wing side adjacent to the elongated hole 41, a guide slot 47 in the form of a step is formed on the intermediate member 25, on which a guide section 49 formed in the area of the arm-side end 37 of the scissors link 17 rests. When the scissors arm 17 is pivoted relative to the intermediate member 25, the guide section 49 slides along the guide slot 47. The course of the guide section 49 has a distance to the pin 43 that decreases continuously from the arm-side end 37 to the side. As a result, when the scissors link 17 is aligned parallel to the intermediate link 25, the pin 43 is held at a greater distance from the guide link 47 than when the scissors link 17 is pivoted out.

This dependence of the position of the fork point 45 within the fork section 39 on the angular alignment of the scissor link 17 relative to the intermediate member 25 or to the entire scissor arm 15 has the consequence that when the sash is tilted, the intermediate member 25 via the shortening of the scissor arm that is inevitably necessary for the tilt lock 15 is also offset by a predetermined amount by the guide link 47 and the guide section 49 in the direction of the pivot member 23, so that the scissor arm 15 is additionally shortened by this amount. This has the consequence of tightening the scissor arm 15, which can at least reduce any play that may be present and which may also lead to a slight displacement of the wing in the direction of the axis of rotation D, which means that the wing can be reliably carried by the scissor arm 15 in a Rotation opening of the wing can be advantageous.

A stop 51 is also formed on the intermediate member 25, by means of which the scissor link 17 is limited to a maximum angular alignment of approximately 45 ° to 50 ° relative to the intermediate member 25 or to the scissor arm 15. The limitation takes place in that the scissor link 17, as in Figure 1b ) shown, strikes the stop 51 when the maximum angular alignment is reached and therefore cannot be deflected any further. The stop 51 thus contributes to the definition of the maximum width of the tilt opening.

As in particular in the longitudinal section of the Fig. 2 As can be seen, the support member 21 is essentially connected to the intermediate member 25 via two pins 53, 53 ', which are provided on the intermediate member 25 on the wing side adjacent to one another along the longitudinal axis L and in each case one of two arranged on the wing side of the support member 21 and Engage parallel to the longitudinal axis L aligned elongated holes 55, 55 'of the same length. In addition, the pin 43 of the scissors link 17 extends through a further one formed in the support member 21 Elongated hole 57. The length of the elongated holes 55, 55 'defines a basic displaceability of the support member 21 relative to the intermediate member 25. In contrast, the further elongated hole 57 is longer in order to enable the additional variability of the position of the fork point 45 within the fork section 39.

The support member 21 is not freely displaceable relative to the intermediate member 25. Instead, locking means 59 are provided in the area between the pins 53, 53 ', which fix the support member 21 in a respective relative position relative to the intermediate member 25. The locking means 59 are designed in the form of a tooth system 61 provided on the support member 21 and a counter tooth system 63 provided on the intermediate member 25. The counter-toothing 63 is formed on a plate 67 that is separate from the rest of the intermediate member 25 and is pretensioned in the direction of engagement with the toothing 61 by means of a spring device 65 designed as a plate spring (cf. Fig. 3 ).

As long as the teeth 61 and the teeth 63 mesh, the support member 21 and the intermediate member 25 form a unit of defined length. A change in length of the scissor arm 15 then results only when the tilt opening and closing is carried out by the lengthening or shortening required for the tilt opening and closing as a result of the displacement of the intermediate member 25 relative to the pivot member 23 and the forced displacement of the fork point 45 within the fork section 39. The length of the scissor arm 15 is shortened or lengthened by fixed values defined by the geometry of the arrangement. In addition, the length of the scissor arm 15 can also be fundamentally adjusted by loosening the toothing 61 and the toothing 63 from each other, in particular to correctly adjust the length of the scissor arm 15 after assembly or after a so-called "setting" of the wing to correct a misalignment of the wing adapt.

As in particular in the enlargement of the Fig. 3 As can be seen, the toothing 61 and the toothing 63 are complementary to one another and asymmetrically designed with tooth flanks aligned perpendicularly in the direction of an extension of the scissor arm 15 and obliquely aligned tooth flanks in the direction of a shortening of the scissor arm 15. In this way, the toothing 61 and the toothing 63 block a displacement of the support member 21 relative to the intermediate member 25 in the direction of an extension of the scissor arm 15, whereas an impact in the direction of a shortening of the scissor arm 15 due to the inclined tooth flanks leads to the fact that the toothing 61 and the toothing 63 are forced out of engagement against the preload, so that the scissor arm 15 can be shortened.

Thus, while a shortening of the scissor arm 15 is permitted by the locking means 59 and in particular takes place automatically when the sash runs onto the frame as a result of an excessively long scissor arm 15 during rotary closure and is thereby raised into the correct orientation relative to the frame, the scissor arm can 15 extend only when the toothing 61 and the toothing 63 are released from one another. This takes place automatically when the sash is tilted open.

For this purpose, the plate 67, in which the counter-toothing 63 is embedded, has laterally, ie transversely to the longitudinal axis L, wing extensions 69 which each have a flank 71 in the direction away from the wing-side end 29 of the scissor arm 15 (cf. Fig. 1 and 4th ). These wing extensions 69 are received in respective receptacles 73, which are formed in the wall sections 34 of the pivot member 23 and each have a corresponding flank 75 (cf. Fig. 4 ).

When the wing is fully open to tilt and thus the intermediate member 25 is furthest relative to the pivot member 23 in the direction of the end on the frame side 27 of the scissor arm 15 is offset, the flanks 71 on the wing extensions 69 interact with the flanks 75 on the receptacles 73 of the pivot member 23 in such a way that the plate 67 is pushed away from the support member 21 against the bias of the spring device 65, so that the Toothing 61 and the toothing 63 are detached from one another. In the tilt-open state, the support member 21 and the intermediate member 25 are thus freely displaceable within the circumference defined by the elongated holes 55, 55 ', so that the length of the scissor arm 15 can automatically adjust, the correct alignment of the supported on the frame in the correct alignment Wing corresponds. If the wing is then tilted closed, the intermediate member 25 is displaced in the direction of the wing-side end 29 of the scissor arm 15, so that the interaction of the flanks 71, 75 ends. As a result, the toothing 61 and the toothing 63 mesh again due to the bias and thereby hold the support member 21 and the intermediate member 25 in the relative position corresponding to the correct alignment of the wing.

In Fig. 5 the scissor arm 15 is shown over its entire length from the wing-side end 29 articulated on the faceplate 13 to the frame-side end 27 arranged on the scissor bearing 26, the Figure 5a ) shows the parallel alignment of the scissor arm 15 relative to the faceplate 13 when the sash is closed or pivoted open, and the Figure 5b ) shows the pivoted position of the scissor arm 15 relative to the faceplate 13 when the sash is tilted open. The extension of the scissor arm 15 required for the tilt opening can clearly be seen in the fact that in the tilt-open state the support member 21 is offset from the pivot member 23 so far that the pivot member 23 protrudes below the support member 21. At the same time, the forced displacement of the fork point 45 within the fork section 39 causes the sash to move slightly away from the axis of rotation D (in Fig. 5 to the left) and when tilting close slightly towards the axis of rotation D (in Fig. 5 to the right), as in Fig. 5 is illustrated by the distance d, which at the embodiment shown is about 4 mm. The relative position of the support member 21 relative to the intermediate member 25 generally does not change, which can be seen from the fact that the pins 53, 53 'maintain their position in the elongated holes 55, 55'.

The 7a) and 7b ) each show a section of the Figure 5a ) or 5b). Corresponding excerpts are also in the Fig. 6a) and 6b ) as well as in the 8a) and 8b ) shown, with the Figures 6 to 8 differ from one another by the length of the scissor arm 15 set in each case. While the scissor arm is 15 in Fig. 7 is set to a medium length, the scissor arm is 15 in Fig. 6 especially short and in Fig. 8 Set particularly long, as can be seen from the corresponding position of the pins 53, 53 'in the elongated holes 55, 55'. This illustrates the flexible adaptability of the fitting arrangement 11 to possible deviations, in particular to possible misalignments of the sash.

Overall, several advantageous properties are thus combined in the fitting arrangement 11 shown. On the one hand, the length of the scissor arm 15 can be automatically adjusted in the tilt-open state and when the sash is rotated by offsetting the support member 21 relative to the intermediate member 25 in order to correct a misalignment of the sash. On the other hand, the joint displaceability of the support member 21 and the intermediate member 25 relative to the pivot member 23 enables the extension or shortening of the scissor arm 15 required for tilt opening and closing, so that the scissor arm 15 can be articulated at a fixed pivot point 19 on the faceplate 13 can. In addition, there is an additional position-dependent lengthening or shortening of the scissor arm 15 when opening or closing the tilt due to the interaction of the guide section 49 with the guide slot 47 to move the fork point 45 within the fork section 39, through which the faceplate 13 (and thus the wing) can be slightly offset in the closed or rotated open state and the scissor arm 15 can be tensioned, so to speak.
