The leg of the handle has a coupling projection and the bearing tape has a coupling receptacle; or it is just the other way around: the bearing tape has a coupling projection and the leg of the carrying handle has a coupling receptacle. The carrying handle and the bearing tape are designed to be positively coupled with one another in that the coupling projection is inserted into the coupling receptacle transversely, preferably orthogonally, to the axis of rotation and then offset parallel to the axis of rotation relative to the coupling receptacle.

Description

The invention relates to a fitting arrangement for the sash of a window, a door or the like, in particular for a sash which can be opened tilt-turn.

Such a fitting arrangement can movably mount the sash on a frame of the window or door. For this purpose, the fitting arrangement is attached to the sash and corresponding counterparts are attached to the frame, on which the fitting arrangement can then be stored. The fitting arrangement can, for example, comprise a swivel arm that is attached to the sash and is connected at one end to a frame-side swivel bearing, for example suspended from it, so that the swivel arm and with it the sash is held by the swivel bearing, but at the same time moved, in particular can be pivoted about the pivot bearing.

Depending on the shape, weight and desired function, in particular depending on the type of opening of the sash, very different fitting arrangements can be used. Typically, a so-called scissor arm is used as a pivot arm for a wing, which should be pivotable and tilt-openable, which enables the side of the wing on which it is provided to be offset parallel to a position that is exclusively radially oriented to the respective bearing so that the wing can be tilted on the opposite side. The named swivel arm can, however, in principle also be designed as a pure rotating hinge arm or pure tilting hinge arm (or rotating or tilting hinge faceplate) or enable other kinematics.

A corresponding variability as in the case of the swivel arms is not required for the swivel bearings, in particular for the so-called scissor bearings, which are typically provided at the top of the respective hinge side of the sash. This is because, as a rule, they only have to allow the respective swivel arm to be pivoted, regardless of the shape and the ability to open the wing.

So that different swivel arms can be mounted on the same swivel bearing, the different swivel arms expediently each have the same bearing band suitable for mounting on the swivel bearing at their end on the hinge side. It is therefore advantageous to manufacture the swivel arm and the bearing tape as separate parts. Another advantage of a two-part design is that a respective swivel arm is not determined in this way on which side of the respective leaf the hinge side is provided on, but can in particular be used on both left and right-opening leaves. Because of the separate design, a suitable bearing tape can be provided in a corresponding orientation on a respective swivel arm as required. This means that the fitting arrangement can be used particularly flexibly.

If the swivel arm and the bearing hinge are designed separately, they still have to be reliably coupled to one another for the assembly of the fitting arrangement on a respective wing. Since the pivot arm generally extends at least substantially radially to the axis of rotation about which it is to be pivotably mounted, the bearing band is typically oriented transversely to the longitudinal extension of the pivot arm. The swivel arm can therefore have a support bracket with a leg at its end on the hinge side, which is angled with respect to the rest of the swivel arm and can be used for coupling to the bearing hinge. For example, the bearing tape can simply be screwed or riveted to the leg of the carrying handle. Such kind of However, coupling means additional effort in the assembly of the fitting arrangement and also requires the use of tools.

It is an object of the invention to provide a fitting arrangement of the type mentioned at the beginning, which can be used flexibly, can be mounted particularly easily and at the same time ensures a reliable coupling of the bearing strip to the swivel arm.

The object is achieved by a fitting arrangement with the features of claim 1. Advantageous embodiments of the invention emerge from the subclaims, the present description and the figures.

The fitting arrangement according to the invention for the sash of a window, a door or the like comprises a swivel arm which, at a hinge-side end of its longitudinal extension, has a carrying handle with a leg angled transversely, in particular orthogonally, to the longitudinal extension, and is designed to be attached to the sash. The wing can in particular be a turn-tilt-openable wing. For this purpose, the swivel arm can in particular be designed as a scissor arm. The swivel arm has in particular an elongated shape which extends between the said end on the band side and an end remote from the band opposite thereto. The two ends define a longitudinal axis of the pivot arm, along which the longitudinal extension is defined.

The carrying handle with the leg angled with respect to the rest of the longitudinal extension of the swivel arm can in principle be designed as a structural unit with the swivel arm. For example, the carrying handle can correspond to a section of the swivel arm and can essentially be formed in that the swivel arm is bent over at its end on the hinge side, so that the bent part forms the leg mentioned. Preferably the handle is however, a component manufactured separately from the swivel arm, which is firmly connected, for example riveted, to the swivel arm. The carrying handle can essentially be designed as an angle with two legs, one of which forms the aforementioned angled leg. The other leg of the handle is then used to attach the handle to the swivel arm and is expediently aligned parallel to the longitudinal extension of the swivel arm.

The swivel arm is preferably designed to be fastened in the fold on one side of the wing, in particular on its upper side. The carrying handle can then be arranged at a corner of the wing and encompass this, in particular in such a way that the angled limb mentioned is oriented at least substantially vertically.

The fitting arrangement according to the invention further comprises a bearing band which is designed to be coupled on the one hand to the support bracket and on the other hand to be pivotably mounted on a frame-side pivot bearing about an axis of rotation. Such a bearing tape is also referred to as a tape bracket. The bearing band can, for example, have a bearing section which is designed as a sleeve into which a bearing pin of the frame-side pivot bearing can engage, so that the bearing band can be rotated about the bearing pin. In addition, the bearing tape can have a coupling section which is designed for coupling to the carrying handle, in particular to the mentioned leg of the carrying handle. The coupling section can, for example, have at least essentially the shape of a plate. The band bearing can be angled in such a way (also several times) that the plane defined by the plate shape of the coupling section deviates from an orientation radial to the axis of rotation, for example by an angle of at least 30 ° and / or at most 60 °, in particular about 45 °. The pivot bearing can in particular be a so-called scissor bearing.

Furthermore, it is provided according to the invention that the leg, i.e. said angled leg, of the carrying handle has a coupling projection and the bearing band has a coupling receptacle, or, conversely, that the bearing band has a coupling projection and the leg of the carrying handle has a coupling receptacle. The number of coupling projections and coupling receptacles is not limited to one, but several coupling projections and several coupling receptacles can be provided on the leg or on the bearing tape. In principle, it is also conceivable that the leg and the bearing strip each have both a coupling projection and a coupling receptacle.

According to the invention, the carrying handle and the bearing tape are designed to be positively coupled to one another in that the coupling projection is inserted into the coupling receptacle transversely, preferably orthogonally, to the axis of rotation and then offset parallel to the axis of rotation relative to the coupling receptacle. The type of coupling according to the invention therefore requires an at least two-part sequence of movements, the two parts of which differ in any case in the direction of the relative movement between the carrying handle and the bearing tape.

First of all, the carrying handle and the bearing tape are moved in such a way that the coupling projection is thereby inserted into the coupling receptacle. This insertion takes place transversely to the axis of rotation, preferably at least substantially orthogonally to the axis of rotation, the axis of rotation being defined in particular by the bearing band, namely by its formation as a bearing pivotable about a defined axis of rotation. For example, the axis of rotation can correspond to a cylinder axis of a sleeve-shaped bearing section of the bearing strip. Said insertion of the coupling projection into the coupling receptacle can take place radially to the axis of rotation. The direction of insertion must be the But do not necessarily cut the axis of rotation. The insertion direction can in particular be at least substantially parallel to the longitudinal extension of the pivot arm.

Secondly, the carrying handle and the bearing tape are moved relative to one another in such a way that the coupling projection, which engages in the coupling receptacle as a result of being inserted, is displaced relative to the coupling receptacle within the coupling receptacle. The direction of this displacement is no longer transverse to the axis of rotation, but parallel to it. The interlocking of the coupling of the carrying handle and the bearing band refers to a release of these two parts from one another (prevented by the interlocking) opposite to the insertion direction and results in particular from the aforementioned offset parallel to the axis of rotation. In other words, as a result of this displacement, the coupling projection is locked in a form-fitting manner against leaving the coupling receptacle against the direction of said insertion. In order to detach the carrying handle and the bearing tape from one another, the form fit must therefore first be canceled again before the coupling projection can be removed from the coupling receptacle against the insertion direction. In this case, the form fit can preferably only be canceled by an offset of the coupling projection relative to the coupling receptacle, opposite to the said offset, parallel to the axis of rotation. The form-fit can result, for example, in that a form-fit structure provided on the coupling projection and a form-fit structure provided on the coupling receptacle engage behind one another with respect to the direction of insertion.

According to an advantageous embodiment, the leg of the carrying handle and the bearing tape each have a contact surface, the contact surface of the leg and the contact surface of the bearing tape in the coupled state, ie when the carrying handle and the bearing tape form-fit in the aforementioned manner are coupled to each other, rest against each other. As a result, an exact relative alignment and reliable mutual support of the carrying handle and the bearing tape on one another is achieved.

According to a further advantageous embodiment, the coupling projection protrudes in the direction of said insertion into the coupling receptacle and has at least one undercut with respect to this direction, which is engaged from behind by a form-fit structure provided on the coupling receptacle as a result of said displacement. For example, the coupling projection can protrude from the mentioned contact surface of the bearing tape or the leg of the carrying handle (depending on whether the coupling projection is provided on the bearing tape or on the carrying handle), in particular orthogonally to the contact surface. Because the interlocking structure engages behind the undercut, the interlocking of the coupling between the support bracket and the bearing tape is then achieved.

For example, the coupling projection can be designed in the manner of a mushroom head, which preferably has a rectangular, in particular square, cross section. The corners of these cross-sectional shapes can also be rounded. The mushroom head corresponds in particular to a structure protruding from a base, for example from the abovementioned contact surface, which has a circumferential widening at its free end spaced from the abovementioned base. The widening of the circumference preferably extends completely around the direction of the protrusion of the structure mentioned. In principle, however, the expansion of the scope can also be interrupted once or several times. The transition between the circumferential extension and an adjoining base section of the cited structure on the base side, which in comparison has a smaller circumference, then forms the cited undercut.

According to a further advantageous embodiment, one or more engagement projections are provided on the coupling receptacle for the positive coupling, which protrude from one or more side walls of the coupling receptacle into the coupling receptacle. In particular, the above-mentioned form-fit structure provided on the coupling receptacle can be formed by these engagement projections or at least include them. The side walls of the coupling receptacle, on which the engagement projections are provided, are preferably aligned parallel to the direction of said insertion. The engagement projections preferably protrude transversely to this direction and / or orthogonally to the respective side wall into the coupling receptacle. The one or more engagement projections can in particular be provided to engage behind said undercut or a respective undercut of the coupling projection when the coupling projection inserted into the coupling receptacle is offset parallel to the axis of rotation relative to the coupling receptacle.

In the direction of said insertion, the engagement projections preferably do not extend over the entire depth of the coupling receptacle, but only over part of it. In particular, this allows the engagement projections to engage behind a respective undercut of the coupling projection for a reliable form-fitting coupling of the support bracket and the bearing band and, in turn, can be engaged from behind by the coupling projection. The part of the depth of the coupling receptacle, over which the engagement projections extend in the insertion direction, preferably adjoins the mentioned contact surface of the carrying handle or the bearing tape and preferably comprises at least 30% and / or at most 70%, for example about 50%, of this depth .

According to a further advantageous embodiment, the carrying handle and the bearing band are designed so that when the coupling projection is inserted into the coupling receptacle, the bearing band is relative to the carrying handle is moved in the direction parallel to the longitudinal extension of the pivot arm in which the said hinge-side end of the pivot arm points. The bearing tape is inserted into the angled leg of the carrying handle from behind, so to speak. As a result, the coupling is particularly stable against tensile forces that typically act on the swivel arm in the direction away from the axis of rotation, that is, in the direction of the opposite end of the swivel arm remote from the strip.

According to a further advantageous embodiment, the carrying handle and the bearing tape are designed so that, when the coupling projection is displaced relative to the coupling receptacle for the positive coupling of the carrying handle and the bearing tape, the bearing tape is moved away in the direction of the said tape-side end of the pivot arm. In other words, after being inserted into the coupling receptacle, the bearing tape is displaced at least substantially away from a longitudinal axis of the swivel arm, along which the named longitudinal extension of the swivel arm is defined, in order to establish the form fit between the coupling projection and the coupling receptacle.

With an arrangement of the swivel arm on an upper side of the respective wing, the carrying handle in this embodiment is thus at least substantially vertically offset upwards relative to the bearing band for establishing the form fit, so that the form fit is vertically offset relative to the bearing band by an opposite offset of the carrying handle is released downwards again. Such an embodiment may therefore appear counterintuitive, since gravity always pulls the sash downwards in relation to the bearing strip mounted on the frame and thus in the direction of releasing the form fit. However, the scissor hinge at the upper end of the hinge side of the sash is usually not used to absorb vertical forces (because the sash is usually already adequately supported in the vertical direction, in particular by the corner hinge), but the absorption of horizontal forces. Therefore, the carrying handle does not threaten to be displaced vertically downwards relative to the bearing tape due to the force of gravity. In the case of very strong horizontal tensile forces, however, these could be deflected at least partially in the direction of pulling upwards by the carrying handle that encompasses one corner of the wing. The present embodiment can advantageously prevent tensile forces deflected in this way from leading to a loosening of the form fit and ultimately to a loosening of the coupling between the carrying handle and the bearing band.

According to a further advantageous embodiment, a latching element is provided on the carrying handle, which is designed to latch onto a latching section of the bearing band when the coupling projection is displaced, so that a release of the positive coupling is blocked by moving the coupling projection in the opposite direction relative to the coupling receptacle . However, alternatively or additionally, it can also be provided in reverse that a latching element is provided on the bearing band which is designed to latch onto a latching section of the carrying handle when the coupling projection is displaced, so that the positive coupling is thereby released opposite displacement of the coupling projection is locked relative to the coupling receptacle. In both cases, the latching takes place preferably shortly before or when a maximally offset position of the coupling projection is reached relative to the coupling receptacle. Such an embodiment can also ensure, regardless of the direction in which the displacement for bringing about or releasing the form fit occurs, that the form fit is not released accidentally or automatically. This is because the latching element would first have to be disengaged, that is to say released from the latching engagement on the latching section.

The latching section can be formed, for example, by an edge of the coupling receptacle, in particular in the area of an edge which has a side surface the coupling recording limited. Such a design has the advantage that the latching section does not have to be designed separately on the carrying handle or on the bearing tape. Rather, the latching element can simply engage in the coupling receptacle itself, if the coupling projection is offset correspondingly far with respect to the coupling receptacle.

According to a further advantageous embodiment, an elastic spring, in particular a leaf spring, is provided on the carrying handle and / or on the bearing band, which biases the carrying handle and the bearing band away from one another parallel to the direction of said insertion. The spring can in particular be arranged between the two mentioned contact surfaces of the carrying handle and the bearing band and can be supported against at least one of the contact surfaces, preferably against both in the coupled state. Furthermore, the spring can be provided at the foot of the coupling projection, i.e. at the end of the coupling projection with which the coupling projection is arranged on the leg of the day hanger or on the bearing band and from which the coupling projection protrudes. For example, the spring can be fastened between the foot of the coupling projection and the respective contact surface. The preload brought about by the spring advantageously increases the friction between the form-fit structures involved in the positive coupling, so that the preload counteracts any accidental or automatic displacement.

In addition to the aforementioned pretensioning function, the spring can also function as the aforementioned latching element. For example, the spring can be arranged between the leg of the carrying handle and the bearing band and bias them away from one another after the coupling projection has been inserted into the coupling receptacle. If, however, the coupling projection is then offset far enough relative to the coupling receptacle transversely to the insertion direction, the spring engages on the latching section. After it clicks into place the carrying handle and the bearing tape are then possibly pretensioned away from one another by the spring with reduced force or no longer at all. It can, however, be provided that at least a part of the spring and / or a further spring that may be provided also then maintains the preload.

According to a further advantageous embodiment, the carrying handle and the bearing tape are designed to be positively locked either in a first configuration or in a second configuration in which the bearing tape is rotated 180 ° compared to the first configuration, preferably about a direction orthogonal to the axis of rotation to be coupled with each other. In particular, it can be provided that the two configurations differ only with regard to the alignment of the bearing tape relative to the swivel arm with the support bracket. In other words, in such an embodiment there are two options for positively coupling the bearing tape to the handle in the manner according to the invention, namely in a first orientation corresponding to the first configuration and in a second orientation corresponding to the second configuration, which is just about 180 °, in particular orthogonally to the axis of rotation, rotated. This makes it possible to use the fitting arrangement equally on opposite sides of the sash (in particular on the left or right) without having to provide different components for these two cases.

With such a design of the carrying handle and the bearing band, it can be advantageous if two elastic springs of the same type, in particular of the type mentioned, are provided, of which one or the other than that, depending on whether the first configuration or the second configuration is present said locking element acts, while the other biases the handle and the bearing tape parallel to the direction of said insertion away from each other. On In this way, both the pretensioning function and the locking function can be implemented in both configurations.

According to a further advantageous embodiment, the coupling projection and the coupling receptacle are designed mirror-symmetrically to a mirror plane which is parallel to the named axis of rotation. The mirror-symmetrical design ensures that the coupling projection and the coupling receptacle, when they are positively coupled to one another, are supported on one another particularly uniformly, in particular on both sides of the mirror plane in corresponding ways. In addition, the above-mentioned mirror symmetry can contribute to the fact that the fitting arrangement, as explained above, can have two different possible configurations of the coupling in order to be able to use the fitting arrangement in particular for both left-opening and right-opening sashes.

This is also promoted by a further advantageous embodiment in which the bearing strip is designed mirror-symmetrically to a mirror plane which is orthogonal to the named axis of rotation. The two mirror symmetries mentioned do not necessarily have to be present together. However, it is preferred that the fitting arrangement has both mirror symmetries.

In the Figs. 1 to 5 a first embodiment of the fitting arrangement 11 according to the invention is shown, while in the Figures 6 to 8 a second embodiment of the fitting arrangement 11 according to the invention is shown. Corresponding elements of the two embodiments are each identified by the same reference number.

In both embodiments, the fitting arrangement 11 each comprises a swivel arm 13, which is designed as a scissor arm in the examples shown, as well as a bearing strip 15. The swivel arm 13 is designed to attach to the top of a turn-tilt-openable sash of a window (not shown ) to be attached. The pivot arm 13 has an elongated shape which extends between an end remote from the band (not included in the detail shown in the figures) and an end 17 on the band side. A longitudinal axis L is defined by the longitudinal extension of the pivot arm 13 between the named ends.

At its end 17 on the hinge side, the swivel arm 13 has a support bracket 19. The carrying handle 19 is essentially designed as an angle which comprises a leg 21 and a further leg 23 which are aligned orthogonally to one another. The carrying handle 19 is firmly connected to the swivel arm 13 in such a way that the leg 21 is angled orthogonally to the longitudinal axis L and points away from the longitudinal axis L, while the further leg 23 is aligned parallel to the longitudinal axis L and from the hinge-side end 17 of the swivel arm 13 points away. The further leg 23 is riveted to the pivot arm 13.

The bearing strip 15 has a bearing section 25 which essentially has the shape of a sleeve. With the bearing section 25, the bearing tape 15 can be mounted on a pivot bearing (not shown), which in the present example is the scissor bearing. This pivot bearing is fixedly attached to the frame of the respective window and has a bearing pin which extends through the sleeve shape of the bearing section 25 so that the bearing strip 15 can be rotated about an axis of rotation D which corresponds to the pin axis of the bearing pin and the cylinder axis of the sleeve shape.

Furthermore, the bearing tape 15 has a coupling section 27 which essentially has the shape of a plate. The transition between the bearing section 25 and the coupling section 27 is angled twice. As a result, the coupling section 27 is offset in parallel with respect to an alignment that is radial to the axis of rotation D.

The pivot arm 13 is designed to be attached to the wing mentioned in such a way that the carrying handle 19 engages around the upper corner of the wing on the hinge side, so that the limb 21 is arranged on one side and the further limb 23 on the other side of the corner . The angled leg 21 serves to couple the swivel arm 13 to the bearing band 15, in particular the support bracket 19 provided on the swivel arm 13 to the coupling section 27 of the bearing band 15.

For the purpose of this coupling, the leg 21 of the carrying handle 19 has a coupling receptacle 29, while the bearing strip 15 has a coupling projection 31 corresponding thereto. The coupling projection 31 and the coupling receptacle 29 each have an at least substantially rectangular basic shape with two sides that are parallel to the axis of rotation D and two sides that are orthogonal to the axis of rotation D. In the direction orthogonal to the axis of rotation D, the extent of the coupling receptacle 29 and the extent of the coupling projection 31 are essentially identical, whereas in the direction parallel to the axis of rotation D the coupling receptacle 29 has a greater extent than the coupling projection 31.

The coupling projection 31 and the coupling receptacle 29 are designed in such a way that the coupling projection 31 can be inserted into the coupling receptacle 29 orthogonally to the axis of rotation D or parallel to the longitudinal axis L until the leg 21 of the carrying handle 19 and the coupling section 27 of the bearing strip 15 rest against one another. The leg 21 is flat such that after insertion, it rests with a contact surface (not visible from the viewing direction of the figures) on a corresponding contact surface 33 of the plate shape of the coupling section 27 of the bearing strip 15. The insertion takes place in the direction parallel to the longitudinal axis L in which the hinge-side end 17 of the pivot arm 13 points. The coupling section 27 of the bearing tape 15 is thereby arranged between the leg 21 of the carrying handle 19 and the wing. After the coupling projection 31 has been inserted into the coupling receptacle 29, there is an intermediate coupling state, which in the Figs. 3 and 4 or in Fig. 7 is shown.

Due to the greater extension of the coupling receptacle 29 parallel to the axis of rotation D compared to the coupling projection 31, the coupling projection 31 can still be offset orthogonally to the longitudinal axis L or parallel to the axis of rotation D after it has been inserted into the coupling receptacle 29. The leg 21 of the carrying handle 19 and the coupling section 27 of the bearing tape 15 slide with their contact surfaces 33 along one another. The coupling projection 31 is offset from one end of the extension of the coupling receptacle 29 parallel to the axis of rotation D to the other end.

The above-mentioned displacement of the coupling projection 31 in the coupling receptacle 29 serves to bring about a form fit of the coupling between the carrying handle 19 and the bearing tape 15. To this end, the coupling projection 31 on the one hand has undercuts 35 and on the other hand the coupling receptacle 29 has engagement projections 37 which are supported by side walls 39 of The coupling receptacle 29 protrude into the coupling receptacle 29 transversely to the insertion direction. The undercuts 35 and the engagement projections 37 are designed and arranged in such a way that the engagement projections 37 engage behind the undercuts 35 as a result of the offset, thereby achieving a positive fit acting against the insertion direction. The coupling of the carrying handle 19 with the bearing tape 15 can therefore only be released again if previously the Positive locking is canceled again by opposing displacement of the coupling projection 31 in the coupling receptacle 29. The coupled state in which the carrying handle 19 and the bearing tape 15 are positively coupled to one another is shown in FIG Fig. 5 or in Fig. 8 shown.

The ones in the Figs. 1 to 5 The first embodiment shown and that in FIGS Figures 6 to 8 The second embodiment shown differ primarily with regard to the design of the coupling projection 31 and the coupling receptacle 29 and the resulting direction of the offset for bringing about the form fit.

In the first embodiment, the coupling projection 29 has a rectangular base section 41 (apart from possibly rounded corners), which is connected to the coupling section 27 of the bearing strip 15, and a head section 43 with a double-T, which protrudes further from the coupling section 27 of the bearing strip 15. Form, the transverse bars of which protrude laterally over the base section 41 with their ends. This results in an undercut 35 at the transition between the protruding ends and the base section 41. The above-mentioned protruding ends of the double-T shape thus represent form-locking structures of the coupling projection 31.

Each of the four laterally protruding ends of the double-T shape of the head section 43 of the coupling projection 31 corresponds to a respective engagement projection 37 projecting laterally from a corresponding side wall 39 of the coupling receptacle 29 part of the depth of the coupling receptacle 29 in the insertion direction, which corresponds to the height of the base section 41 of the coupling projection 31, and are arranged in such a way that the coupling projection 31 is only inserted into the coupling receptacle 29 at one end of the extension of the coupling receptacle parallel to the axis of rotation D. 29 allow. If the laterally protruding ends of the double-T shape of the coupling projection 31 are then passed past the engagement projections 37, the coupling projection 31 can then be moved parallel to the axis of rotation D to the other end, where the engagement projections 37 then engage behind the undercuts 35. The arrangement of the engagement projections 37 is such that the displacement to bring about the form fit takes place in the direction of the hinge-side end 17 of the pivot arm 13.

As a further difference to the second embodiment, two springs 45 are provided in the first embodiment, each of which is designed as a leaf spring. The two springs 45 are made in one piece and fastened between the coupling projection 31 and the contact surface 33 of the coupling section 27 of the bearing strip 15, each protruding with an elastic tongue in opposite directions parallel to the axis of rotation D over the coupling projection 31. As a result, the springs 45 are effective between the contact surface of the leg 21 of the support bracket 19 on the one hand and the contact surface 33 of the coupling section 27 of the bearing tape 15 on the other hand and thereby tension the support bracket 19 and the bearing tape 15 away from each other. This is especially true in Fig. 4 can be seen in which the leg 21 of the handle 19 with the coupling receptacle 29 is shown partially in section.

Like comparing the Fig. 4 with the Fig. 5 shows, after the aforementioned displacement, one of the two springs 45 can engage in the coupling receptacle 29 and thereby engages on the edge of the coupling receptacle 29 at the transition between the side wall 39 facing away from the hinge-side end 17 of the pivot arm 13 and the contact surface 33. In this respect, this edge represents a snap-in section 47 of the carrying handle 19, while one of the two springs 45 represents a snap-in element 49. The latching of the latching element 49 on the latching section 47 prevents the coupling projection 31 from being able to be set back against the direction of said displacement. In this way, the Positive locking secured against unintentional loosening. However, the latching can be canceled manually, for example by pressing against the latching element 49 using a screwdriver.

Because the coupling projection 31 and the coupling receptacle 29 are rotationally symmetrical with respect to a rotation by 180 ° about an axis parallel to the insertion direction, the bearing tape 15 can be positively coupled to the carrying handle 19 in two different configurations. This makes it possible to use the fitting arrangement 11 for both left-hand and right-hand openable sashes. This also contributes to the fact that the bearing strip 15 as a whole is designed to be mirror-symmetrical to a mirror plane orthogonal to the axis of rotation D. Depending on which of the two configurations is selected, one or the other of the two springs 45 then functions as the aforementioned latching element 49.

In the second embodiment, in contrast to the first embodiment, two coupling projections 31 and two coupling receptacles 29 are provided. However, these are designed and arranged on the bearing belt 15 or on the leg 21 of the day hanger 19 in such a way that the symmetries mentioned are also present there. Therefore, the second embodiment also enables a positive coupling of the bearing tape 15 with the support bracket 19 in two different configurations.

In the second embodiment, the coupling projections 31 are each designed in the manner of a mushroom head with (apart from rounded corners) a square cross-section. The mushroom head shape comprises a base section 41 adjoining the contact surface 33 of the bearing tape 15 and a head section 43 which protrudes further from the contact surface 33 and whose circumference is widened compared to the base section 41 in such a way that it protrudes laterally all the way around the base section 41. At the An undercut 35 is formed as a result of the transition between the head section 43 and the base section 41.

Corresponding engagement projections 37 are formed on the two coupling receptacles 29. In the second embodiment, these extend transversely to the direction of extension over the entire side wall 39 of the respective coupling receptacle 29 pointing away from the hinge-side end 17 of the pivot arm 13 or from the longitudinal axis L and subsequently also partially over the side walls 39 adjoining it on both sides, so that the engagement projections each have a U-shape. The engagement projections 37 each extend parallel to the insertion direction from the contact surface of the leg 21 of the carrying handle 19 only over part of the depth of the coupling receptacle 29, which corresponds to the height of the base section 41 of the coupling projections 31.

Due to the above-mentioned arrangement of the engagement projections 37, the positive locking is brought about in the second embodiment (in contrast to the first embodiment) by displacing the coupling projection 31 inserted into the coupling receptacle 29 in the direction away from the hinge-side end 17 of the swivel arm or from the longitudinal axis L. (see. Figures 7 and 8 ). By changing the arrangement of the engagement projections 37 on the respective coupling receptacle 29, however, the first embodiment could also be modified so that the positive coupling takes place by shifting away from the longitudinal axis L, and the second embodiment could also be modified so that the positive coupling takes place by offsetting on the longitudinal axis L.

In particular, because of the opposite direction of the above-mentioned displacement, a latching element 49 can be dispensed with in the second embodiment. In principle, however, can also be in the second embodiment or a plurality of springs 45 and / or one or more latching elements 49 with a corresponding function as in the first embodiment can be provided.
