Description

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

Such a fitting arrangement can mount the sash movably 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 the so-called hinge side of the window or door, on which the fitting arrangement can then be mounted movably, in particular pivotally, by means of a bearing band. The fitting arrangement can, for example, comprise an elongated swivel arm, which is attached to the wing and is connected at its hinge-side end via the bearing band to a swivel bearing to be provided on the frame, for example by hooking the bearing band onto the swivel bearing, so that the swivel arm and with it the Wings are held by the pivot bearing, but at the same time can be moved, in particular pivoted about an axis of rotation defined by the pivot bearing. A particularly suitable bearing band is a so-called band angle, which can be angled one or more times in order to achieve a certain offset between the swivel arm and the swivel bearing.

Depending on the shape, weight and desired function, especially depending on the way the sash can be opened, very different fitting arrangements can be used. Typically, a so-called scissor arm is used as a swivel arm for a sash that is intended to be both rotary and tilt-openable, which allows the side of the sash on which it is provided to be aligned exclusively radially to the respective bearing to be displayed parallel, so that the sash is thereby tilted on its opposite side. In principle, the swivel arm mentioned can also be designed as a pure rotating hinge arm or purely tilting hinge arm (or rotating or tilting hinge forend) or enable other kinematics of the sash relative to the frame.

A corresponding variability as with the swivel arms is not necessary for the swivel bearings, especially for the so-called scissor bearings, which are typically provided at the top of the respective hinge side of the sash. As a rule, they only have to enable the respective swivel arm to be pivoted and are therefore essentially independent of the shape of the wing and the way it can be opened. The bearing band, via which a swivel arm is mounted on a swivel bearing, can therefore be designed in the same way for different swivel arms. For this reason, it is advisable to manufacture the bearing bands not as an integral part of the swivel arms, but as separate parts, which are then each firmly connected to a swivel arm. In this way, different swivel arms can be produced, but each have the same bearing band.

Another advantage of a two-part design is that a respective pivot arm is not determined from the outset as to where the hinge side of the wing is, i.e. around which of its sides the wing can be pivoted. In particular, a respective swivel arm can in principle be used on both left-hand and right-hand opening sashes. Only by coupling it to a bearing belt is the swivel arm then fixed to a specific side of the belt. This determination can result from the choice of the bearing band and/or the type of arrangement of the bearing band on the swivel arm. In the latter case, the fitting arrangement can also be changed by changing the alignment of the bearing band on the swivel arm be reconfigurable. This means that the fitting arrangement can be used particularly flexibly.

However, if the swivel arm and the bearing band are designed separately, it is important that these parts are reliably coupled to one another at the latest when the fitting arrangement is installed on a respective sash. Particularly in the swung-open state, the wing is largely supported by the frame via this coupling.

The swivel arm typically extends radially to the axis of rotation and is therefore attached to one of the sides of the wing that are aligned perpendicular to the hinge side. The bearing band, on the other hand, is usually arranged on the band side of the wing for interaction with the pivot bearing. It is therefore expedient if the swivel arm has a carrying handle at its belt-side end, which includes a leg that is angled relative to the rest of the swivel arm and which can be used for coupling to the bearing belt.

For example, the bearing band can simply be screwed or riveted to the angled leg of the carrying handle. However, such a type of coupling requires the use of tools and therefore means additional effort when assembling the fitting arrangement. A rivet connection is also irreversible, meaning that the fitting arrangement can no longer be reconfigured if the wrong pivot arm is selected or the wrong hinge side is set.

A type of connection that is easy to close, yet reliable and can also be detached again can be achieved using a bayonet lock. For this purpose, it can be provided in particular that there is a bayonet receptacle on the carrying handle of the swivel arm and on a coupling section of the bearing band a bayonet bolt is provided. The carrying handle and the bearing band can be inserted into one another and fastened to one another by turning the bayonet bolt in the bayonet receptacle.

However, there is a fundamental risk that the bayonet pin will rotate in the bayonet receptacle over time, for example due to the actuation of the wing or vibrations that occur, and the connection will become loose as a result. This risk is even greater if the bayonet bolt is turned after being inserted into the bayonet receptacle, but not enough so that the actual coupling position is not reached at all. Finally, there is also the risk that when assembling the fitting arrangement, turning the bayonet bolt inserted into the bayonet receptacle to lock the bayonet catch is simply forgotten, since the swivel arm and the bearing band already appear connected by simply being plugged in, even though they are not yet secured to one another in a form-fitting manner are.

A fitting arrangement according to the preamble of claim 1 is, for example DE 40 40 233 A1 known. Further, fundamentally similar fitting arrangements are presented in DE 19 23 282 U , DE 41 09 636 A1 , DE 30 24 746 A1 and DE 20 2004 019551 U1 described.

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

The object is achieved by a fitting arrangement with the features of claim 1. Advantageous embodiments of the invention result 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 is designed to be attached to the sash and which has a carrying handle with a leg angled transversely to the longitudinal extent at a hinge-side end of its longitudinal extent. The wing can in particular be a turn-tilt-openable sash. For this purpose, the swivel arm can be designed in particular as a scissor arm. The swivel arm in particular has an elongated shape which extends between said band-side end and an opposite, band-remote end. The two ends define a longitudinal axis of the swivel arm, along which the said longitudinal extent is defined.

The carrying handle with the leg that is angled relative to the rest of the longitudinal extent 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 band-side end, so that the bent part forms the said leg. Preferably, however, the carrying handle is a component manufactured separately from the swivel arm, which is firmly connected to the swivel arm, for example riveted. The carrying handle can essentially be designed as an angle with two legs, one of which forms the aforementioned angled leg. The further leg of the carrying handle then serves to attach the carrying handle to the swivel arm and is expediently aligned parallel to the longitudinal extent of the swivel arm.

The swivel arm is preferably designed to be fastened in the rebate on one side of the sash, in particular on its top side. The carrying handle can then be arranged at a corner of the wing and encompass it, in particular in such a way that said angled leg is at least essentially vertically aligned.

The fitting arrangement further comprises a bearing band which is designed to be pivotably mounted with a bearing section on a pivot bearing to be provided on the frame of the window or door about an axis of rotation of the pivot bearing to be, and which has a coupling section which can be coupled to the angled leg of the carrying handle of the swivel arm by means of a bayonet lock.

The bearing section mentioned can, for example, be 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. The mentioned coupling section of the bearing band can, for example, have at least essentially a plate shape. The bearing band can in particular be designed as a so-called band angle. The bearing band can be angled (even multiple times) in such a way that the plane defined by the plate shape of the coupling section deviates from a radial orientation to the axis of rotation, for example by an angle of at least 30° and/or at most 60°, in particular approximately 45°. The pivot bearing can in particular be a so-called scissor bearing.

The bayonet lock comprises a bayonet bolt extending along a bolt axis and a bayonet receptacle, which are designed in such a way that, in order to close the bayonet lock, the bayonet bolt is inserted axially into the bayonet receptacle with respect to the bolt axis and is then rotated relative to the bayonet receptacle about the bolt axis into a coupling position, in the form-fitting means of the bayonet bolt engage behind the form-fitting means of the bayonet receptacle and thereby lock the bayonet pin against axial exit (with respect to the bolt axis) from the bayonet receptacle. In particular, it can be provided that the said stretching is a pure translational movement, i.e. is not superimposed by any rotation. The subsequent rotation into the coupling position, on the other hand, can also be superimposed by movement components in the axial direction, for example in the manner of a screwing movement and/or for overcoming a locking edge.

In principle, it can also be a pure rotation without any movement components in the axial direction.

After the bayonet pin is inserted into the bayonet receptacle, but before it is then rotated relative to the bayonet receptacle, the bayonet pin is in a release position in which the positive locking means of the bayonet pin do not engage behind the corresponding positive locking means of the bayonet receptacle and the bayonet pin is therefore again axially out of the Bayonet mount can come out. By turning the bayonet bolt back from the coupling position to the release position, the positive connection can therefore be canceled again and the bayonet lock can thus be released again.

In other words, the bayonet bolt and the bayonet receptacle are designed in particular in such a way that, in order to close the bayonet lock, the bayonet bolt is inserted axially into the bayonet receptacle with respect to the bolt axis and is then rotated relative to the bayonet receptacle about the bolt axis from a release position into a coupling position, in the coupling position Positive locking means of the bayonet bolt engage behind corresponding positive locking means of the bayonet receptacle and thereby lock the bayonet bolt against axial exit from the bayonet receptacle, but not in the release position; Thus, the bayonet bolt and the bayonet receptacle can advantageously also be designed in such a way that, in order to open the bayonet lock, the bayonet bolt is rotated relative to the bayonet receptacle about the bolt axis from the coupling position into the release position and is then removed axially from the bayonet receptacle with respect to the bolt axis.

The bayonet bolt is preferably arranged on the bearing band, with the bayonet receptacle then being provided on the carrying handle. In principle, the bayonet pin can also be arranged on the carrying handle in the opposite way; In this case, the bayonet mount is then provided on the bearing band.

The positive locking means can each be formed in particular by radial projections with respect to the bolt axis, for example bayonet wings, and/or radial depressions, for example undercuts, grooves or link guides. In particular, the bayonet bolt can have one or more such projections, preferably at least two bayonet wings, and the bayonet receptacle can have one or more such recesses, preferably at least two undercuts. In principle, however, the bayonet receptacle can also have one or more radial projections and/or the bayonet bolt can have one or more radial recesses.

According to the invention, a securing spring with a locking tongue is provided on the bayonet receptacle, which is arranged in such a way that when the bayonet bolt is axially inserted into the bayonet receptacle, it is acted upon by the bayonet bolt and is deflected axially into a deflection position with respect to the bolt axis against a restoring force of the securing spring and by this Turning the bayonet pin into the coupling position is released for returning to a locking position, into which it is moved due to the restoring force of the securing spring and in which it locks the bayonet pin, in particular in a form-fitting manner, against rotation out of the coupling position.

The locking tongue can in particular be designed integrally with the securing spring. In principle, it is also possible for the locking tongue to be designed separately and to be attached to the securing spring, preferably to a free end of the securing spring.

The securing spring can in particular be provided on the bayonet receptacle in that it is attached to the component (bearing band or carrying bracket) on which the bayonet receptacle is provided and is adjacent to the bayonet receptacle, overlaps with it when viewed in a direction parallel to the bolt axis and/or each other extends into the bayonet mount.

Due to the described mode of operation according to the invention, the locking tongue of the safety spring automatically engages when the bayonet lock is closed by inserting the bayonet bolt into the bayonet receptacle and rotating the bayonet bolt relative to the bayonet receptacle. The insertion causes the deflection and thus tensioning of the safety spring with the locking tongue. The rotation then enables the locking tongue to be axially reset to its locking position due to the pretension of the safety spring and thereby to snap into place on the bayonet pin. In the locked state, i.e. when the bayonet pin inserted into the bayonet receptacle is in the coupling position and the locking tongue assumes its locking position, the bayonet pin is secured against leaving the coupling position.

The latching is preferably such that it is accompanied by acoustic feedback. In other words, the latching can preferably be heard clearly, for example as a click or clack. In this way, a fitter of the fitting arrangement advantageously receives clear feedback as to whether the bayonet lock is closed reliably, namely secured by the locking tongue, or not. This contributes to safe use of the fitting arrangement.

To open the bayonet lock, the securing of the bayonet bolt must first be released again by the locking tongue in order to unlock the bayonet bolt and enable it to be rotated out of the coupling position. In order to open the bayonet lock, it is advantageously necessary to move the locking tongue again from the locking position into the deflection position against the restoring force mentioned.

Preferably, when the locking tongue assumes its locking position, the securing spring is not completely relaxed, but continues to exert a pre-tension in the direction the stated restoring force. In other words, the locking tongue is biased in its locking position in the direction away from the deflection position. This makes it very unlikely that a vibration is capable of moving the locking tongue so far out of the locking position that the bayonet pin is released, let alone moving the bayonet pin simultaneously from the coupling position to the release position. This means that automatic opening of the bayonet lock is almost impossible.

According to the invention, the locking tongue of the safety spring is arranged such that it engages in the bayonet receptacle in the locked position. In this way, the locking tongue can interact particularly easily with the bayonet bolt inserted into the bayonet receptacle in order to lock it. In particular, the locking tongue can block a path that a part of the bayonet bolt, in particular the positive locking means of the bayonet bolt, would travel when rotating out of the coupling position. By engaging in the bayonet receptacle, the locking tongue can preferably be supported radially outwards on the bayonet receptacle with respect to the bolt axis and thereby lock the bayonet pin particularly reliably.

According to an advantageous embodiment, the locking tongue of the securing spring is arranged such that it engages in the bayonet receptacle, at least as long as the bayonet bolt is not inserted into the bayonet receptacle. In this way, the locking tongue can, so to speak, be in the way of the bayonet pin when it is inserted into the bayonet receptacle and can therefore be acted upon axially by the bayonet pin in a simple manner.

According to a further advantageous embodiment, the bayonet bolt has at least one (relative to the bolt axis) radially projecting bayonet wing as a positive locking means, whereby when the bayonet bolt is inserted into the bayonet receptacle and rotated into the coupling position, the locking tongue of the securing spring in its locking position in the circumferential direction (with respect to the bolt axis) rests against the bayonet wing and thereby blocks the bayonet bolt against rotation out of the coupling position, preferably in a form-fitting manner. The locking tongue is preferably designed to be complementary to the bayonet wing in such a way that it rests on the bayonet wing not only at points, but at least along a contact line, preferably along a contact surface.

It is particularly preferred if the locking tongue in the locking position both rests on the bayonet wing and engages in the bayonet receptacle and is supported on the bayonet receptacle radially outwards with respect to the bolt axis. This can ensure that the locking tongue is clamped between the bayonet wing and the bayonet receptacle when the bayonet pin is forced to rotate out of the coupling position, whereby the bayonet pin is blocked particularly reliably against such a rotation.

According to a further embodiment, it is further advantageous if the bayonet bolt, when it is inserted into the bayonet receptacle, acts on the locking tongue of the securing spring with a bayonet wing that projects radially (with respect to the bolt axis), in particular with the bayonet wing mentioned above, and deflects it into the deflection position. The bayonet wing therefore not only serves to couple the bayonet pin with the bayonet receptacle by reaching behind the corresponding form-fitting means of the bayonet receptacle, but can also serve to push back the locking tongue when the bayonet pin is inserted into the bayonet receptacle and then turn away from under the locking tongue so that it is behind can spring back into place on the bayonet wing.

According to a further advantageous embodiment, the securing spring is designed as a leaf spring, which is attached to the carrying handle or the bearing band with a fastening section and has a spring arm which is elongated Structure extends away from the fastening section, the locking tongue being formed by an end section of the spring arm. A leaf spring has the particular advantage that it takes up comparatively little space. Said spring arm can extend between a fixed end adjacent to the fastening section and a free end, said end section then preferably being formed at the free end.

In this embodiment, the locking tongue is formed by said end section of the spring arm, and is therefore an integral part of the spring arm and thus of the securing spring. The spring arm can, for example, be designed as a substantially flat strip. The locking tongue can then be formed by a single or multiple bent end section of the strip and thereby protrude at least partially, in particular vertically, from the remaining spring arm. Alternatively, the locking tongue can also lie in the same plane as the rest of the spring arm.

If the securing spring is designed as a leaf spring, an embodiment may also be advantageous in which at least said fastening section of the securing spring is inserted into a receiving recess formed on the carrying bracket or the bearing band, which has a shape that is complementary to the shape of at least the fastening section of the securing spring. This complementary design means that the leaf spring, which is inserted into the receiving recess at least with its fastening section, is particularly well secured against slipping. Preferably, the leaf spring is also attached in such a way that it cannot be removed from the receiving recess. For example, one or more edge sections of the receiving recess can be formed into lugs which protrude over the fastening section of the leaf spring and thereby block it from leaving the receiving recess.

According to an alternative advantageous embodiment, the securing spring is designed as a leg spring with a first leg and a second leg, which is mounted on the carrying handle or the bearing band and is supported on it with the first leg, while the locking tongue is formed by an end section of the second leg . The leg spring can in particular comprise, in a conventional manner, a wire which is wound helically around a spring axis in a central section of the leg spring and whose opposite ends form two legs, namely the first leg and the second leg, which are at least extend essentially in a straight line away from the central section. In the assembled state, the two legs are preferably pretensioned towards one another in the direction of rotation around the spring axis. Such a leg spring can generate a comparatively large force, which can help ensure that the locking tongue engages particularly securely on the bayonet pin.

In such an embodiment, the locking tongue is formed by said end section of the second leg, and is therefore an integral part of the second leg and thus of the securing spring. The second leg can extend between a fixed end, with which the leg merges into the helically wound central section, and a free end, with said end section then preferably being formed at the free end. In the end section, the second leg can be bent to form the locking tongue, while otherwise it preferably has an at least essentially straight course. For example, the end section can be bent so that it has a course that is complementary to a contour of a bayonet wing of the bayonet bolt, against which it rests when the bayonet bolt is in the coupling position and the locking tongue is in the locking position. In addition, a curved end section can serve to define an application plane which is acted upon by the bayonet bolt when it is inserted into the bayonet receptacle.

According to a further advantageous embodiment, the bayonet bolt is attached to the bearing band or to the carrying handle so that it can rotate about a bolt axis. In particular, the bayonet bolt can have a driving profile, for example a hexagon socket or a hexalobular socket, preferably on an end face facing away from the bearing band or the carrying handle, in order to be able to be easily rotated with an appropriate tool for closing or opening the bayonet lock .

The ones in the Fig. 1 to 3 or 4 to 6 shown two embodiments of a fitting arrangement 11 according to the invention essentially differ in terms of the design of the respective securing spring 13, but otherwise largely agree with one another. Identical or corresponding components are each marked with the same reference number.

The fitting arrangement 11 is intended for use on the sash of a window, a door or the like (not shown) and comprises a swivel arm with a carrying handle 15 and a bearing band 17. Of the swivel arm, which is in particular a scissor arm for a rotary -tilt-openable wing can act, only the carrying handle 15 is shown, which is provided at the hinge-side end of the swivel arm and is designed as an angle with a leg 19 angled transversely to the longitudinal extent of the swivel arm and a further leg 21 parallel to the longitudinal extent.

The bearing band 17 is designed as a band angle and has a substantially sleeve-shaped bearing section 23, into which a bearing pin of a frame-side pivot bearing, not shown, can engage in order to pivot the bearing band 17 and ultimately the entire pivot arm about an axis of rotation of the pivot bearing via the carrying bracket 15 To store pivot bearings. The bearing band 17 also has a plate-shaped coupling section 25, which is angled relative to the bearing section 23 in such a way that it is offset parallel to an orientation radial to the axis of rotation.

The carrying handle 15 and the bearing band 17 can be coupled to one another via the angled leg 19 and the coupling section 25. There is also a bayonet lock 27 is provided, which comprises a bayonet bolt 29 formed on the coupling section 25 of the bearing band 17 and a bayonet receptacle 31 formed in the leg 19 of the carrying bracket 15. The bayonet bolt 29 extends along a bolt axis B (cf. Fig. 2 or 5), to which it is designed to be rotationally symmetrical.

To close the bayonet lock 27, the bayonet bolt 29 is inserted axially, ie parallel to the bolt axis B, into the bayonet receptacle 31 and then relative to the bolt receptacle 31 about the bolt axis B into the Fig. 1, 2 and 3c or 4, 5 and 6c shown coupling position rotated. The bayonet bolt 29 is rotatably mounted on the coupling section 25 of the bearing band 17. For easy rotation of the bayonet bolt 29, a driving profile 33 is formed in an end face of the bayonet bolt 29, which faces away from the coupling section 25, which is designed as a hexalobular socket in the embodiments shown.

In the coupling position, positive locking means 35 of the bayonet bolt 29 engage behind corresponding positive locking means 37 of the bayonet receptacle 31, whereby the bayonet bolt 29 is secured against axial exit from the bayonet receptacle 31. The positive locking means 35 of the bayonet bolt 29 are designed as two bayonet wings, which are formed by two projections which project radially outwards in opposite directions with respect to the bolt axis B.

The corresponding positive locking means 37 of the bayonet receptacle 31 are formed by two undercuts, which are arranged opposite one another in a corresponding manner to the bayonet wings of the bayonet bolt 29 and are therefore each engaged by one of the bayonet wings when the bayonet bolt 29 is in its coupling position. On the other hand, if the bayonet bolt 29 is rotated by 90° relative to the coupling position in the in Fig. 3a or 6a shown release position, the bayonet wings can be guided past the undercuts, so that the bayonet bolt 29 can be inserted axially into the bayonet receptacle 31 or can also be removed axially from the bayonet receptacle 31 to release the coupling.

An anti-twist device is also provided between the leg 19 of the carrying handle 15 and the coupling section 25 of the bearing band 17. The anti-rotation device comprises a projection 39 formed on the leg 19 of the carrying bracket 15, which in the coupled state provides parallel to the bolt axis B from the leg 19 in the direction of the coupling section 25 of the bearing band 17, as well as a recess 41, which is on the coupling section 25 of the bearing band 17 is trained. The projection 39 and the recess 41 are arranged such that the projection 39 engages in the recess 41 when the bayonet bolt 29 is axially inserted into the bayonet receptacle 31, this engagement blocking rotation of the bearing band 17 relative to the carrying bracket 15.

A further recess 41 'is formed on the coupling section 25, which is arranged symmetrically to the recess 41 mentioned with respect to the bolt axis B. In this way, the bearing band 17 can be coupled to the carrying handle 15 in two different orientations so that the fitting arrangement 11 can be used for both left-hand opening and right-hand opening sashes. In the alternative orientation not shown in the figures, the projection 39 does not engage in the recess 41, but rather in the further recess 41 '.

A safety spring 13 is also arranged on the leg 19 of the carrying handle 15. In the two embodiments shown, the securing spring 13 is arranged on that side of the leg 19 which is aligned opposite to the side with which the leg 19 rests in the coupled state on the coupling section 25 of the bearing band 17. The safety spring 13 has a locking tongue 43, each of which is formed by an end portion of an elongated structure of the securing spring 13. With this locking tongue 43, the securing spring 13 overlaps the bayonet receptacle 31 and also engages in the bayonet receptacle 31 depending on whether the bayonet bolt 29 is inserted into the bayonet receptacle 31 and which rotational position it assumes.

The process of closing the bayonet lock 27 and the function of the safety spring 13 are determined for the two embodiments shown Figs. 3a-3c or 6a-6c illustrated. In the Fig. 3a and 6a the bayonet bolt 29 is in its release position with respect to its rotatability about the bolt axis B, in which the positive locking means 35 of the bayonet bolt 29 and the corresponding positive locking means 37 of the bayonet receptacle 31 are aligned offset from one another in the circumferential direction, so that they can be guided past one another axially. Therefore, the bayonet bolt 29 can be inserted axially into the bayonet receptacle 31.

When inserting the bayonet bolt 29 into the bayonet receptacle 31, the locking tongue 43 of the locking spring 13 is acted upon by one of the bayonet wings of the bayonet bolt 29 and in the direction of insertion, i.e. axially with respect to the bolt axis B, into an in Fig. 3b or 6b shown deflected. The deflection takes place against a restoring force of the securing spring 31, which increases with increasing deflection.

In the deflection position, the securing spring 31 therefore presses axially with its locking tongue 43 against the bayonet bolt 29, which, however, does not prevent it from coming out of the in Fig. 3a or 6a shown release position via the in Fig. 3b or 6b shown intermediate position into the in Fig. 3c or 6c shown coupling position to be rotated. The bayonet wing through which the locking tongue 43 was deflected rotates away under the locking tongue 43. As a result, the locking tongue 43, When the bayonet bolt 29 has reached its coupling position, the restoring force of the securing spring 13 causes it to return axially into the in Fig. 3c or 6c shown safety position offset and locks behind the bayonet wing.

In the securing position then assumed, the locking tongue 43 engages in the bayonet receptacle 31 and rests laterally on the bayonet wing that previously acted upon it. The locking tongue 43 is located in the movement path of the bayonet wing, which it would have to cover in order to turn the bayonet bolt 29 back into the release position. The result of this is that the bayonet bolt 29 is positively locked by the safety spring 13 against turning back from the coupling position into the release position. In addition, the locking tongue is supported radially outwards against the bayonet receptacle 31, so that it cannot be pushed out of the way by the bayonet bolt 29. To prevent further rotation in the other direction, i.e. rotation beyond the coupling position, the bayonet bolt 29 is also blocked by a locking contour 45 formed on the bayonet receptacle 31. Consequently, the bayonet lock 27 is reliably secured in its closed state by the securing spring 13, in particular against automatic loosening, for example due to vibrations.

The movement sequence for an intended opening of the bayonet lock 27 corresponds to a reversal of the process for closing the bayonet lock 27. However, unlike when closing, where it automatically locks into place due to the restoring force, the locking tongue 43 must be moved manually into the deflection position when opening before the Bayonet bolt 29 can be rotated back into the release position and then removed axially from the bayonet receptacle 31.

At the in the Fig. 1 to 3 In the first embodiment shown, the securing spring 13 is designed as a leaf spring. The leaf spring has a fastening section 47, with which it is attached to the leg 19 of the carrying handle 15. For this purpose, a receiving recess 49 is formed on the leg 19, which opens into the bayonet receptacle 31 and into which the securing spring 13 is inserted. The shape of the receiving recess 49 is complementary to the shape of the part of the locking spring 13 inserted into it, so that the locking spring 13 does not take up any additional installation space and is securely stored.

The fastening section 47 is held securely in the receiving recess 49 by edge sections of the receiving recess 49 which are each formed into a nose 51. An elongated spring arm 53 of the securing spring 13 extends from the fastening section 47 to the bayonet receptacle 31. An end section of this spring arm 53 at its free end (i.e. remote from the fastening section 47) forms the locking tongue 43. The locking tongue 43 has a contour which on the one hand to a contour of the bayonet receptacle 31 and on the other hand to a contour of the bayonet bolt 29, between which the locking tongue 43 is arranged when the bayonet bolt 29 is inserted into the bayonet receptacle 31 and rotated into its coupling position and the locking tongue 43 is in its locking position .

At the in the Fig. 4 to 6 In the embodiment shown, the locking tongue 43, on the other hand, is designed as a leg spring, which is inserted into a spring receptacle 55 formed in the leg 19 of the carrying bracket 15 and is supported with a first leg 57 on the leg 19 of the carrying bracket 15, while the second leg 59 of the leg spring is up to extends to the bayonet receptacle 31 and is biased axially in the direction into the bayonet receptacle 31. An end section at the free end of the second leg 59 forms the locking tongue 43. The second leg 59 is bent at its free end in such a way that it is supported on the one hand on a contour of the bayonet receptacle 31 and on the other hand is adapted to a contour of the bayonet bolt 29, between which the locking tongue 43 is arranged when the bayonet bolt 29 is inserted into the bayonet receptacle 31 is inserted and rotated into its coupling position and the locking tongue 43 is in its locking position.

Just as in the case of a design as a leaf spring, the securing spring 13 designed as a leg spring can automatically snap into place behind the positive locking means 35 of the bayonet bolt 29 with its locking tongue 43 when the bayonet lock 27 is closed and thereby reliably secure the bayonet lock 27 against automatic opening.

Claims (8)

1. A fitting arrangement (11) for the leaf of a window, of a door or the like, said fitting arrangement (11) comprising

   - a pivot arm which is configured to be fastened to the leaf and which has, at a hinge-side end of its longitudinal extent, a stay support (15) having a leg (19) angled transversely to the longitudinal extent, and

   - a support band (17) which is configured to be pivotably supported with a bearing section (23) at a pivot bearing, which is to be provided at the frame of the window or the door, about an axis of rotation of the pivot bearing and which has a coupling section (25) which can be coupled to the angled leg (19) of the stay support (15) of the pivot arm by means of a bayonet fastening (27),

   wherein the bayonet fastening (27) comprises a bayonet pin (29) extending along a pin axis (B) and a bayonet receiver (31), said bayonet pin (29) and bayonet receiver (31) being configured such that, in order to close the bayonet fastening (27), the bayonet pin (29) is axially plugged into the bayonet receiver (31) with respect to the pin axis (B) and is subsequently rotated relative to the bayonet receiver (31) about the pin axis (B) into a coupling position in which form-fitting means (35) of the bayonet pin (29) engage behind corresponding form-fitting means (37) of the bayonet receiver (31) and thereby block the bayonet pin (29) against axially exiting from the bayonet receiver (31), and

   wherein a securing spring (13) comprising a latching tongue (43) is provided at the bayonet receiver (31), said latching tongue (43) being arranged such that:

   - on the axial plugging of the bayonet pin (29) into the bayonet receiver (31), the latching tongue (43) is acted on by the bayonet pin (29) and is axially deflected into a deflection position with respect to the pin axis (B) against a return force of the securing spring (13); and

   - by rotating the bayonet pin (29) into the coupling position, the latching tongue (43) is released for a return into a blocking position into which it is displaced due to the return force of the securing spring (13) and in which it blocks the bayonet pin (29) against a rotation out of the coupling position,

   characterized in that

   the latching tongue (43) of the securing spring (13) is arranged such that it engages into the bayonet receiver (31) in the blocking position.
2. A fitting arrangement in accordance with claim 1,
   wherein the latching tongue (43) of the securing spring (13) is arranged such that it engages into the bayonet receiver (31) as long as the bayonet pin (29) is not plugged into the bayonet receiver (31).
3. A fitting arrangement in accordance with one of the preceding claims,

   wherein the bayonet pin (29) has at least one radially projecting bayonet leaf as the form-fitting means (35),

   and wherein, when the bayonet pin (29) is plugged into the bayonet receiver (31) and rotated into the coupling position, the latching tongue (43) of the securing spring (13), in its blocking position, contacts the bayonet leaf in the peripheral direction and thereby blocks the bayonet pin (2) against a rotation out of the coupling position.
4. A fitting arrangement in accordance with claim 3,
   wherein the bayonet pin (29), when it is plugged into the bayonet receiver (31), acts on the latching tongue (43) of the securing spring (13) with said bayonet leaf and deflects said latching tongue (43) into the deflection position.
5. A fitting arrangement in accordance with any one of the preceding claims, wherein the securing spring (13) is configured as a leaf spring which is fastened with a fastening section (47) to the stay support (15) or the support band (17) and which has a spring arm (53) which extends as an elongate structure away from the fastening section (47), wherein the latching tongue (43) is formed by an end section of the spring arm (53).
6. A fitting arrangement in accordance with claim 5,
   wherein at least the fastening section (47) of the securing spring (13) is inlaid into a receiving recess (49) which is formed at the stay support (15) or the support band (17) and which has a shape complementary to the shape of at least the fastening section (47) of the securing spring (13).
7. A fitting arrangement in accordance with any one of the claims 1 to 4,
   wherein the securing spring (13) is configured as a leg spring which has a first leg (57) and a second leg (59), which is supported at the stay support (15) or the support band (17) and which is supported thereat with the first leg (57), while the latching tongue (43) is formed by an end section of the second leg (59).
8. A fitting arrangement in accordance with any one of the preceding claims, wherein the bayonet pin (29) is rotatably fastened about its pin axis (B) to the support band (17) or to the stay support (15).
