Description

[0001] The invention relates to a fastening for a drive rod fitting of a window or door, provided in a guide groove of a wing having a first and second undercut, according to the preamble of claim 1.

[0002] For fastening in a C-shaped guide groove with undercuts in the sash of a window or door, the drive rod fitting according to the invention consists of a drive rod, the drive rod having a base plate with webs arranged perpendicular to the base plate. A first web and a second web together form a fastening groove with an axis of symmetry. A first longitudinal side of the drive rod has a free end section extending from the base plate, which reaches into the first undercut of the guide groove. A second longitudinal side of the drive rod, opposite the first longitudinal side and extending from the base plate, forms a retaining projection that engages almost completely in a second undercut of the guide groove.Additionally, the second longitudinal side of the drive rod has a third web which, with a shoulder arranged at its free end outside the guide groove, rests on a web formed by the undercut of the guide groove. For a secure and firm hold and for resistance-free movement of the drive rod fitting in the undercut guide groove of the sash, the drive rod fitting according to the invention further comprises a coupling element which can be connected to the drive rod.The coupling element partially clamps the connecting rod in cross-section, thereby filling the first undercut of the guide groove almost without play in a form-fitting manner together with the end section of the connecting rod and joining it with the connecting rod by means of a retaining element pre-mounted and rotatably mounted on the coupling element, which belongs to a further component of the connecting rod fitting according to the invention, by rotating the retaining element over a tool within the guide groove to form a one-piece component.

[0003] Furthermore, the invention relates to a method for mounting the drive rod fitting for a secure and movable hold in a C-shaped guide groove having undercuts of a sash of a window or door.

[0004] The assembly principle of the invention is a so-called frontal assembly.

[0005] It is possible to insert the individual fitting components frontally into the guide groove, or perpendicular to the guide groove, with undercuts on the sash. Known systems that utilize the frontal mounting principle require many components. Particular attention must be paid to mounting the fitting components of the locking rod mechanism frontally or perpendicularly to the sash's guide groove. The locking rod mechanism can detach from the guide groove and potentially fall out, which complicates installation.

[0006] It is known to mount a drive rod fitting on a guide groove, in particular a guide groove with undercuts, of a sash. Various mounting methods for this purpose have already been established: From EP 3 162 995 B1, a fitting assembly with a sash of a window or door is known. In this assembly, a C-shaped groove has a first groove section and a second groove section in the rebate area with a fitting assembly of the aforementioned type arranged on the frame profile of the sash. Furthermore, the invention relates to a method for frontally mounting a fitting assembly of the aforementioned type in a C-shaped groove in the rebate area of ​​a frame profile of a sash of a window or door.

[0007] The present locking rod fitting requires additional fitting components for vertical mounting in a C-shaped guide groove of the sash, ensuring a secure hold. These components necessitate further assembly. A locking device, consisting of a locking body, a locking arm, and a spring arm, is spring-loaded and connected to a bearing body. Once installed, it engages an undercut in the C-shaped guide groove to securely hold the locking rod fitting. Due to the number of components, attaching the locking device proves to be complex, and the necessary dimensional coordination further increases the overall cost.Furthermore, the pre-drilled holes in the connecting rod for a positive-locking connection of the locking device to the bearing body do not allow for any further alignment in the longitudinal direction of the guide groove or in the direction of the sliding adjustment of the connecting rod fitting. Therefore, adjustment is not possible. This also complicates assembly and increases the cost of the connecting rod fitting.

[0008] A drive rod fitting of the type mentioned above is also known from EP 1 707 719 B1. This drive rod fitting is suitable for door and window frames made of frame members, which have guide slots with a bottom wall, two side walls, and two longitudinal edges facing each other and running parallel to the bottom wall. The longitudinal edges define a longitudinal opening whose width is less than the distance between the side walls, so that, viewed in cross-section, the slot has an undercut profile. Each longitudinal edge has an outer surface, an end surface, and an inner surface. The drive unit has several drive elements designed for insertion into the corresponding slots with a movement transverse to the longitudinal direction of the slot. Each drive element has two parallel side surfaces and a single tenoning element extending parallel to one of the side surfaces.wherein each of the drive elements has at least one longitudinal support edge which projects laterally beyond an associated side surface and is designed to contact the outer surface of the corresponding longitudinal edge of the slot when the tenoning element is inserted under the other longitudinal edge of the slot, until the parallel side surface adjacent to the tenoning element is brought into contact with the front surface of the edge and thus the drive element is caused to oscillate towards the interior of the slot.

[0009] The drive rod of this device can be pivoted vertically into a C-shaped undercut guide groove. However, a secure hold against the drive rod potentially falling out during a sliding adjustment of the drive rod fitting is only achieved with the coupling connection of other functional components. Particularly with large windows or doors, large gaps arise in which the drive rod is positioned in the guide groove without any further support and is therefore unsecured. Free adjustment with a sliding movement of the drive rod can thus lead to problems. Similarly, unsecured gaps arise between the sash and the frame of the window or door, which can also negatively impact security against break-ins.

[0010] Reference is further made to EP 2 754 802 A2. This arrangement comprises a first fitting component as a locking bar and a second fitting component as a locking element. The locking element can be inserted into the locking bar. The locking bar, in turn, is inserted into a groove between a rebate area of ​​the sash. The locking element has laterally projecting groove sections into which locking strips of the locking bar engage.

[0011] Reference is also made to EP 0 283 984 A1, which describes a self-locking coupling, particularly for profile elements of window sashes, doors, and window frames. This coupling has a coupling flap with corresponding coupling projections at its end. These projections are narrower and longer than the distance between the opposing wings of a C-shaped profile groove in the door or window frame, which defines the coupling seat. A slanted section on the flat, free end of the coupling projections ensures a secure clamping hold against further longitudinal displacement of the profile groove, even if the coupling is rotated using a tool. The coupling projections engage in the undercut C-shaped profile groove.

[0012] The object of the present invention is to eliminate the known defects and, in contrast, to provide a drive rod fitting for a window or door with optimal guidance when adjusting the drive rod fitting for a window or door, at low cost and with little installation space, which can also be installed and adjusted and dismantled in a simple, quick, safe and precise manner even afterwards, but in particular further simplifies the installation.

[0013] This problem is solved by a drive rod fitting for a window or door with the features of claim 1.

[0014] The drive rod fitting according to the invention is arranged in such a way that it can be easily and securely mounted vertically in an undercut guide groove arranged on the sash of a window or door and can be moved, depending on the design variant, partially or completely to the frame of the window or door by actuating an operating means, for a secure locking in a closed position or an open turn and / or tilt position of the sash.

[0015] In this context, a drive rod of the drive rod fitting according to the invention has, in cross-section, a base plate with three webs arranged perpendicular to the base plate. The first web and the second web are preferably symmetrically shaped relative to each other and form a fastening groove with an axis of symmetry. Also in cross-section, a first longitudinal side of the drive rod, extending from the base plate, has a free end section. This end section is adapted to the thickness of the base plate and extends into an undercut of the guide groove formed by a first groove leg, with the height of the undercut being filled to half its original depth. A second longitudinal side on the opposite side of the drive rod, extending from the base plate, forms a retaining projection and the third web.The retaining element engages almost positively in a second undercut of the guide groove formed by a second groove leg, with the third web leaning against the second groove leg which limits the opening and extending beyond the overlying guide groove, supporting itself on the second groove leg with a shoulder arranged at its free end outside the guide groove and pointing away from the opening of the guide groove.

[0016] Furthermore, in a preferred embodiment, the connecting rod fitting features a coupling element which, formed in one piece, covers an opening of the guide groove flush with the surface and clamps the connecting rod between the undercuts up to the free end section. At the respective free ends of the coupling element, projections angled perpendicular to the connecting rod are formed, with the first projection being angled again and following the end section of the connecting rod, engaging in the first undercut of the guide groove and filling the first undercut with the end section almost without play. In a further advantageous embodiment, upon engagement of the projection in the first undercut, the second projection of the coupling element engages perpendicularly to the guide groove through the opening into a groove open perpendicular to the base plate of the connecting rod, thus providing a positive locking connection.For simplicity, the groove is formed by the second and third webs of the connecting rod. With the coupling element engaging in the groove, it rests flush on the first and second webs and the end section of the connecting rod, perpendicular to the guide groove of the wing, in a pre-positioned end position. Furthermore, a retaining element with a head is preferably permanently but rotatably attached to the coupling element.The retaining element is divided into three stages perpendicular to the axis of rotation. The plate-like head section on the coupling element prevents perpendicular displacement relative to the axis of rotation. A middle section is rotatably mounted in a bore of the coupling element and has a foot section at its end. In a first, pre-assembled position, the foot section, with a width between the first and second webs forming the mounting groove in the connecting rod, allows for displacement of the coupling element along the longitudinal direction of the guide groove on the connecting rod to reach its final position. Secured against lateral displacement in the connecting rod by the projections of the coupling element and the retaining element in a positive-locking position, the coupling element can be moved longitudinally and, upon reaching its final position, locked securely to the connecting rod with a positive and force-locking connection.

[0017] For fixing purposes, undercuts are arranged in the cross-section of the connecting rod on the webs of the fastening groove pointing towards the axis of symmetry, into which, with rotatable displacement of the retaining element on the coupling element about an axis of rotation of the retaining element, the foot part with a projection and a length L greater than the width B engages in the undercut of the webs in a form-fitting clamping manner and with a ring cutting edge projecting on the foot part in a force-fit interlocking manner assumes a mounted position of the connecting rod with the coupling element.

[0018] Depending on the stress and size of the sash, the number of coupling elements on the drive rod fitting can be adjusted as needed. All coupling elements, together with the retaining link, are identically designed and functionally lockable for cost-effective fixing of the drive rod in the sash's guide groove.

[0019] To achieve a cost-effective product with simple manufacturing and implementation using few components, the coupling element is connected to the drive rod as a one-piece component to form a longitudinally displaceable drive rod fitting in the guide groove of the wing by means of an operating element.

[0020] Due to the identical alignment of the axis of symmetry of the drive rod with the axis of the guide groove and the rotation axis of the retaining element, congruent alignment with the axis of symmetry of the drive rod, other locking element-relevant components of the wing with the locking parts facing the frame can be easily adjusted.

[0021] Advantageously, the coupling element is positioned separately from the connecting rod in a pre-assembled position with the retaining element being rotatably displaced around its own axis of rotation and perpendicular to the axis of rotation in the direction of the connecting rod, whereby the coupling element and the connecting rod are pressed against each other, occupy a backlash-free connecting position in the guide groove, and can be displaced together.

[0022] The retaining element proves to be simple in manufacture and easy in handling, as the head part forms a flush surface on the visible surface of the coupling element and is rotatably mounted with a middle part in a bore of the retaining element.

[0023] A simplified fixing of the coupling element with the drive rod in the guide groove and a secured operative coupling of the drive rod fitting in the interlocking guide groove is achieved by arranging the central part of the retaining member between the opening of the guide groove and the fastening groove of the drive rod, whereby with rotatable displacement of the retaining member the play between the fastening groove and the central part decreases when the drive rod is in a fixed position with the coupling element for adjustment of the drive rod fitting.

[0024] In addition to the positive locking connection of the coupling element with the connecting rod by the coupling element itself via the projections and via the retaining member with engagement of the projections in the undercut, in a further preferred embodiment the coupling element is additionally anchored by frictional clamping with an incising ring cutting edge on the foot part of the retaining member during the rotatable displacement of the retaining member into a projection on the base plate of the connecting rod.

[0025] In the design of the coupling element, in addition to the positive-locking and force-locking connecting elements to the drive rod and the sliding guide in the guide groove, the provision of a cost-effective and easy-to-handle actuating device is also important. For this purpose, the retaining element has a tool engagement for a rotary tool, allowing the retaining element to be rotated by 90°. For secure guidance and a secure hold of the drive rod fitting in the guide groove of the sash, the retaining element has a T-shaped cross-section within the drive rod's mounting groove, and its cross-section is adapted to the shape of the mounting groove, consisting of the cavity and the undercuts.

[0026] Furthermore, the invention includes a method for facilitating the assembly and / or adjustment of a drive rod fitting in a guide groove of a window or door sash for the sliding actuation of the drive rod fitting in the guide groove, comprising the following steps: a) Using a guide groove with a cross-section through an opening over a horizontal and vertical side of the wing behind grippable undercuts a1) Inserting a connecting rod into the guide groove with secure hold when moving the connecting rod by engaging an end section arranged on a first longitudinal side of the connecting rod in extension of the base plate into the first undercut and engaging a retaining projection arranged on a second longitudinal side of a base plate of the connecting rod into the second undercut, wherein at the same time a shoulder of the connecting rod having a web at the end is supported on the guide groove, a2) Pre-assembling a retaining element onto a coupling element with secure hold by placing a head part of the retaining element on an end face of the coupling element for rotatable displacement on the coupling element in order to couple the coupling element with the connecting rod, a3) Inserting the pre-assembled coupling element together with the retaining element through the opening of the guide groove for a secure hold for positionable displacement in the longitudinal direction of the guide groove, by engaging a projection of the coupling element in the first undercut of the guide groove with the projection resting on the end section on the first longitudinal side of the connecting rod for an almost backlash-free engagement in the first undercut, a4) Further joining of the pre-assembled coupling element together with the retaining member within the opening of the guide groove for a secure hold during a positionable displacement in the longitudinal direction of the guide groove, by positively interlocking a projection of the coupling element into a groove of the drive rod on the second longitudinal side, wherein the coupling element covers the drive rod flush in cross-section within the opening of the guide groove in its end position, a5) Determining and securing a position of the coupling element on the connecting rod in the guide groove against further displacement of the coupling element and securing the connecting rod fitting against further displacement and falling out of the connecting rod fitting from the guide groove of the sash, with rotatable displacement of the retaining member by means of a tool in engagement of a tool engagement on the retaining member for a force-fit clamping connection by means of a ring cutting edge of the retaining member and a projection on the connecting rod.

[0027] Furthermore, additional advantageous process steps result from the fact that a) the coupling element with the drive rod as an integral component to form a drive rod fitting for safe movement in the sash by means of a1) Engagement of the holding element in the undercut, support of the shoulder of the drive rod on the guide groove and a2) The engagement of the projection of the coupling element in the resting position connects with the end section of the connecting rod in the undercut of the guide groove of the wing.

[0028] Further advantages of the invention will become apparent from the description and the drawing. Likewise, the features mentioned above and those described in more detail below can each be used individually or in any combination according to the invention. The embodiments shown and described are not to be understood as an exhaustive list, but rather serve as examples for illustrating the invention.

[0030] The Fig. Figure 1 shows a perspective view of a sash 3 of a window or door. To operate the rotatable, tiltable, or rotatable and tiltable sash 3, an operating element 41 is arranged on a vertical mullion 40, which controls a drive rod fitting 4 according to the invention. By actuating the operating element 41, the drive rod fitting 4 according to the invention can be adjusted, for example, from a locked closed position (not shown) to an open position of the sash 3 relative to a fixed frame (not shown) in the direction of arrow 42 (not shown), whereby the sash 3 assumes a secured, offset ventilation position or the area of ​​a turn or tilt opening. The sash 3 is supported and movably connected to the frame (not shown) by one or more hinges, as shown in the drawing, at an upper and lower corner of the sash 3 by means of straps 43, 44.The opening and closing of the wing 3 is effected via the operating element 41, which in this version is an operating handle that can be rotated 90° and / or 180° from a vertically oriented position. The operating handle 41 then acts according to . Fig. 2 together with a gearbox 45, which in turn interacts with the drive rod fitting 4 according to the invention. For mounting the drive rod fitting 4, a circumferential profile 46 is arranged on the sash 3, which has a C-shaped guide groove 1 open towards the frame for guiding and securing the drive rod fitting 4 according to the invention. Between the guide groove 1 on the sash 3 and the circumferential profile of the frame (not shown) there is a gap, which is referred to as the rebate area.

[0031] The drive rod fitting 4 according to the invention, which can be located on one or more sides in the rebate area of ​​the profile 46 of the sash 3, has according to Fig. 1 and Fig. 3 a drive rod 5, a coupling element 16 and a retaining member 21. Optionally, the coupling element 16 can also have a locking element 32 in the form of a locking pin or mushroom-head pin. Furthermore, the coupling element 16 can be used as a carrier element for retrofittable accessories such as magnetic pins, actuators, sensors or other functional elements.

[0032] After Fig. 4 and Fig. In cross-section, the connecting rod 5 of the connecting rod fitting 4 has a base plate 6 with three webs 7, 7', 7'' arranged perpendicular to the base plate 6. The first web 7 and the second web 7' are symmetrically oriented towards each other and together form a fastening groove 8 with an axis of symmetry 9. Also in cross-section, a first longitudinal side 10 of the connecting rod 5, extending from the base plate 6 and spaced apart from the first web 7, has a free end section 11. The end section 11 is adapted to the thickness of the base plate 6 and extends to Fig. 5 into an undercut 2 of the guide groove 1 formed by a first groove leg 33, the height of the undercut 2 being half-filled by the end section 11. A second longitudinal side 12 of the connecting rod 5, on the opposite side of the first longitudinal side 10, forms a retaining projection 13 and the third web 7'' in continuation of the base plate 6. The retaining projection 13 extends according to Fig. 4 and Fig. 5 from the third web 7'' and engages almost without play in a second undercut 2' of the guide groove 1. The third web 7'' rests against a second groove leg 33' that defines the opening 17 and forms a stop in the transverse direction of the longitudinal guide groove 1. Furthermore, the third web 7'' overlaps the second groove leg 33' of the guide groove 1 with a shoulder 15 located at its free end 14. In the end position of the connecting rod 5 in the guide groove 1, the shoulder 15 rests on the groove leg 33' and, together with the base plate 6, forms a guiding support for the connecting rod fitting 4 in the guide groove 1. Simultaneously, the groove leg 33' is engaged by the retaining projection 13 and the third web 7'', which functionally provides further longitudinal guidance for the connecting rod fitting in the guide groove 1.

[0033] Furthermore, the connecting rod fitting 4 in preferred embodiment shows Fig. 3 and Fig. 9 a coupling element 16. The coupling element 16 is formed in one piece and its length in the longitudinal direction covers the guide groove 1 in cross-section according to Fig. 3 and Fig. 8 The opening 17 of the guide groove 1 is flush with the surface. Furthermore, the coupling element 16 clamps the connecting rod 5 between the undercuts 2, 2' up to the free end section 11 of the connecting rod 5. After Fig. In cross-section, projections 18 and 18' are formed at the respective free ends of the coupling element 16, perpendicular to the connecting rod 5, at a 90° angle. The first projection 18 is angled again by 90° away from the undercut 2, with the projection 18 following the end section 11 of the connecting rod 5 in a supporting manner and engaging with the end section 11 in the first undercut 2 of the guide groove 1, filling the undercut 2 almost without play. With the projection 18 engaged in the first undercut 2, the second projection 18' of the coupling element 16 engages perpendicularly to the guide groove 1 through the opening 17 into a groove 19 open perpendicular to the base plate 6 of the connecting rod 5, providing positive engagement. The webs 7' and 7'' of the connecting rod 5 are spaced apart from each other in such a way that the groove 19 is formed for the positive locking reception of the projection 18'.All webs 7, 7', 7'' are functionally significant at their respective outer contours, whereby webs 7, 7' and 7'' both assume positionable guiding properties and contribute to a connection of the coupling element 16 to the connecting rod 5. With engagement of the coupling element 16 in the groove 19 according to... Fig. 3 and Fig. 8, the coupling element 16 lies flush on the first and second web 7, 7' and on the end section 11 of the connecting rod 5, perpendicular to the guide groove 1 of the wing 3 in a pre-positioned end position.

[0034] The coupling element 16 is permanently attached, but rotatable. Fig. 3, Fig. 11 to Fig. 13 a retaining member 21 with a head part 20 is anchored. The head part 20 is effectively connected to the coupling element 16 in an assembly process by wobbling or riveting. After Fig. 14 The retaining member 21 divides perpendicularly to the axis of rotation 25 into three sections. The first section is a plate-shaped head section 20, which is mounted flush on the coupling element 16 and prevents perpendicular displacement to the axis of rotation 25. The second section consists of a cylindrical middle section 22, which is rotatably mounted in a bore 29 of the coupling element 16. An end foot section 23, which constitutes the third section, is located in a free actuation area relative to the coupling element 16 and is stepped in the direction perpendicular to the axis of rotation 25. A first step 34 of the foot section 23 is associated with a narrow section of the opening of the mounting groove 8, while a second step 35 of the foot section 23 faces the base plate 6 of the connecting rod 5 and is positioned in the extended area of ​​the undercut 24, 24' of the mounting groove 8.In a first pre-assembled position, the coupling element 16 with the retaining member 21 is joined in the connecting rod 5. The retaining member 21, with a width B at the base 23, can be moved within the connecting rod 5 between the first web 7 and second web 7' forming the mounting groove 8, to achieve a correct final position of the coupling element 16 in the longitudinal direction of the guide groove 1. Furthermore, the base 23 is designed to accommodate... Fig. 8 and Fig. 13 to Fig. 14 a ring cutting edge 27 is arranged which can be moved freely within a free operating field inside the mounting groove 8 without engaging the retaining member 21. Secured against lateral displacement in the connecting rod 5 by the projections 18, 18' and the retaining member 21 in a positive-locking position, the coupling element 16 with the retaining member 21 can be moved longitudinally along the connecting rod 5 upon reaching its final end position and thus secured to the connecting rod 5 in a force-locking and positive-locking manner.

[0035] This is according to Fig. 6 and Fig. 11 to Fig. 12 in the cross-section of the connecting rod 5 within the fastening groove 8 on the webs 7, 7' pointing towards the axis of symmetry 9, undercuts 24, 24' are arranged, into which, with rotatable displacement of the retaining member 21 on the coupling element 16 about the axis of rotation 25 of the retaining member 21, the foot part 23 with a projection 26, 26' and a length L Fig. 14 engage in the undercut 24, 24' of the webs 7, 7' in a form-fitting manner and, with a ring cutting edge 27 projecting at the head of the foot part 23, force-fit combing, assumes a mounted position of the connecting rod 5 with the coupling element 16.

[0036] The coupling element 16 is selected according to the stress and size of the wing 3. Fig. The number of coupling elements on the connecting rod fitting 4 can be adjusted as required. All coupling elements 16 are designed identically with the retaining member 21 for cost-effective fixing of the connecting rod 5 in the guide groove 1 of the sash 3 and can be locked in a functionally identical manner.

[0037] With a firm, form-fit and force-fit connection of the coupling element 16 to the connecting rod 5 according to Fig. 1 and Fig. 12, the drive rod fitting 4 can be guided longitudinally in the guide groove 1 of the sash 3 by means of the operating element 41 in the longitudinal direction of the guide groove 1 to all available positions of the sash 3 to the frame of the window or door.

[0038] With the same alignment of the axis of symmetry 9 of the connecting rod 5 with the axis of the guide groove 1 and the axis of rotation 25 of the retaining member 21 according to Fig. 8, further locking elements 32 relevant components of the wing 3 can be easily adjusted with the locking parts facing the frame.

[0039] After Fig. 8 and Fig. In section 11, the coupling element 16 and the connecting rod 5 are pre-assembled in the guide groove 1 for longitudinal displacement to form a fixed connection. Upon reaching an end position of the coupling element 16 together with the retaining member 21 in a guided position relative to the connecting rod 5, the retaining member 21 is rotated 90° about its own axis of rotation 25. During this rotational movement of the retaining member 21, the coupling element 16 and the connecting rod 5 move perpendicular to each other to form a backlash-free, pressed-in connection. For this purpose, the projections 26, 26' point towards Fig. 11 and Fig. 12 on the free surfaces for optimal entry into the undercuts 24, 24' of the fastening groove 8 and a bevel 36 to form a contact pressure.

[0040] After Fig. 3 and Fig. 11 to Fig. 12 The retaining member 21 consists perpendicular to its axis of rotation 25 of the plate-like head part 20, which rests flush on the visible surface 28 of the coupling element 16 and prevents the retaining member 21 from being moved further in a perpendicular direction to the axis of rotation 25, further consisting of a middle part 22 rotatably mounted in a bore 29 of the coupling element 16 and a foot part 23, which is divided into two stages 34, 35 and enables the positive locking and force-locking fixing of the coupling element 16 in the connecting rod 5.

[0041] The fixing of the coupling element 16 with the connecting rod 5 in the guide groove 1 and the secured operative coupling of the connecting rod fitting 4 in the interlocking guide groove 1 is thus achieved by the fact that the foot part 23 of the retaining member 21 is arranged in a stepped form in a free actuation field of the fastening groove 8 of the connecting rod 5, whereby with rotatable displacement of the retaining member 21 according to Fig. 11 The play between the coupling element 16 and the connecting rod 5 is continuously reduced. The connection of the connecting rod 5 with the coupling element 16 is triggered by the rotation of the first and second stages 34, 35 of the foot part 23 of the retaining member 21 into the undercuts 24, 24' arranged in the fastening groove 8. In the engaged position, the connecting rod fitting 4 is in a position within the guide groove 1 of the wing 3, secured against falling out and guided by a drive mechanism.

[0042] For the rotatable adjustment of the retaining member 21 in the coupling element 16, the retaining member 21 has a tool engagement 31 for a rotary tool in the exemplary embodiment shown on its visible side and on the flat side of the coupling element 16 above the guide groove 1. Fig. 3 and Fig. 13 to Fig. 14 in the form of an internal hexagon. Using the rotary tool, the retaining element 21 can be effectively adjusted by 90°, so that by rotating the retaining element 21 the drive rod fitting 4 is moved into the permanently secured engagement position, which can be moved in the longitudinal direction of the guide groove 1 of the wing 3.

[0043] According to the invention, the mounting and / or adjustment of the drive rod fitting 4 in the guide groove 1 of the sash 3 of the window or door for the sliding actuation of the drive rod fitting 4 in the guide groove 1 is Fig. 5 to Fig.12 proposed in the following steps, wherein all components of the drive rod fitting 4 are located outside the guide groove 1 of the wing 3. a) Using a guide groove 1 arranged on the wing 3 with a cross-section through an opening 17 over a horizontal and vertical side of the wing 3 behind grippable undercuts 2, 2', a1) Insertion into the guide groove 1 of a connecting rod 5 with secure hold when the connecting rod 5 is moved by engaging an end section 11 arranged on a first longitudinal side 10 of the connecting rod 5 in extension of the base plate 6 into the first undercut 2 and engaging a retaining projection 13 arranged on a second longitudinal side 12 of a base plate 6 of the connecting rod 5 into the second undercut 2', wherein at the same time a shoulder 15 of the connecting rod 5 having a web 7'' at the end 14 is supported on the guide groove 1, a2) Pre-assembling a retaining member 21 onto a coupling element 16 with secure hold by resting a head part 20 of the retaining member 21 on an end face 28 of the coupling element 16 for a rotatable displacement on the coupling element 16 in order to couple the coupling element 16 with the connecting rod 5, a3) Insertion of the pre-assembled coupling element 16 together with the retaining member 21 through the opening 17 of the guide groove 1 for a secure hold during positionable displacement in the longitudinal direction of the guide groove 1 by engaging a projection 18 of the coupling element 16 in the first undercut 2 of the guide groove 1 in a resting position of the projection 18 on the end section 11 on the first longitudinal side 10 of the connecting rod for an almost backlash-free engagement in the first undercut 2, a4) Further joining of the pre-assembled coupling element 16 together with the retaining member 21 within the opening 17 of the guide groove 1 with a secure hold during positionable displacement in the longitudinal direction of the guide groove 1 by inserting a projection 18' of the coupling element 16 into a groove 19 of the drive rod 5 on the second longitudinal side 12 of the drive rod 5 for a positive fit, wherein the coupling element 16 covers the drive rod 5 flush in cross-section within the opening 17 of the guide groove 1 in its end position. a5) Determining and securing a position of the coupling element 16 on the connecting rod 5 in the guide groove 1 against further displacement of the coupling element 16 and securing the connecting rod fitting 4 for secure displacement against falling out of the connecting rod fitting 4 in the guide groove 1 of the wing 3 with rotatable displacement of the retaining member 21 by means of a tool in engagement of a tool engagement 31 on the retaining member 21 for a force-fit connection by means of a ring cutting edge 27 of the retaining member 21 and a projection 30 on the connecting rod 5.

[0044] Furthermore, additional advantageous process steps result from the fact that a) the coupling element 16 connects with the connecting rod 5 as an integral component, wherein the connecting rod fitting 4 forming the connecting rod is designed for safe movement in the wing 3 by means of a1) Engagement of the retaining element 11 in the undercut 2' and support of the shoulder 13 of the connecting rod 5 on the guide groove 1, as well as with a2) The engagement of the projection 18 of the coupling element 16 in a resting position with the end section 15 of the connecting rod 5 in the undercut 2 of the guide groove 1 of the wing 3 allows it to be moved in the guide groove 1 of the wing 3 in a securing manner.
