[0002] Fastening device for a drive rod fitting component

[0003] The invention relates to a fastening device for a drive rod fitting component on a sash rebate of a sash composed of profiled bars. The sash rebate is profiled and has a double C-shaped guide groove, which has two webs extending perpendicular to the rebate and two opposing edge strips. The edge strips run parallel to the rebate and a groove base. This creates an undercut between the groove base and the edge strip. A drive rod mounted along the sash rebate is guided longitudinally displaceably in the groove and engages behind the undercut. This secures the drive rod against removal from the guide groove. However, the same circumstance also prevents the drive rod from being mounted in a direction perpendicular to the rebate.Therefore, designs were used that provide for the partial removal of webs and edge strips in the joint area of ​​two profile bars, so that the guide groove is opened and the drive rods can be inserted along the sash rebate. This is time-consuming and requires space at the installation point equal to the maximum length of the drive rod. Consequently, various designs have already become known that allow the drive rods and drive rod components to be inserted perpendicular to the sash rebate.

[0004] From DE 19962152 A1, fastening devices are known which allow for a mounting movement perpendicular to the sash rebate. Here, a fastening device for an angled drive rod element is disclosed, which incorporates locking elements for mounting in the previously described rebate groove. In addition, pivotable clamping elements are disclosed which, in a mounting position, are aligned with the outer edges of the housing and can thus be guided between the legs of the guide groove. The clamping elements can be rotated into a locking position in which they engage in the undercut.

[0005] DE 7132734 U1 discloses a fastening device for a corner deflection housing. The device features a recess in the corner of the sash, allowing the insertion of a housing leg with two longitudinal grooves that engage the edge strips. An adjustable clamping element is provided on the second leg. In a first position, this clamping element aligns the housing so that the first leg can be inserted along the guide groove until the housing rests on the base of the groove of the orthogonal leg. This secures the first leg of the housing to the sash. A 90° rotation of the clamping element also secures the second leg of the housing, which rests against the edge strip with a flat surface. The angled housing is thus fixed to the sash. This design requires a recess on at least one profile bar of the sash.

[0006] To secure a strike plate fitting in a rebate groove, DE 3041500 A1 provides that a strike plate is engaged by a U-shaped spring with outwardly facing cutting edges at its V-shaped diverging side edges. In its first position, the spring engages the narrowed waist of the strike plate, so that the cutting edges do not protrude beyond the width of the strike plate. As the spring is moved along the strike plate, the V-shaped diverging side edges of the strike plate spread the spring, causing its cutting edges to dig into the side walls of the rebate groove. This design is suitable for sash profiles made of soft materials, but not for those made of metal.

[0007] DE 2015723 A1 proposes an angled housing with elastic locking tabs along the longitudinal side edges on both legs. The locking tabs are mounted parallel to the housing's side walls and have undercuts at their ends that engage behind the locking lugs of the rebate groove. No clearance of the rebate groove is required for assembly. The locking tabs are integral to the housing and must therefore be made of the same material. This design requires that the locking tabs have sufficient clearance. To prevent the locking tabs from disengaging, locking elements are incorporated into the housing, which support the locking tabs against the housing in the locked position. Pins or threaded bolts are proposed for this purpose. After the locking tabs are engaged during assembly, the locking elements are retracted behind the locking tabs, preventing them from being pushed back.The design allows for only complex disassembly, as the locking elements must first be removed and the locking tongues then pushed back.

[0008] A similar design is known from DE 4138741 A1, in which the locking tongues are attached to a clamp that overlaps the angled housing on one leg. Lateral projections are provided on the second leg, which engage in the undercut of the rebate groove and thereby fix the leg. These projections necessitate partial removal of the edge strips for assembly. Therefore, mounting the housing perpendicular to the rebate is not possible.

[0009] From DE 102021203760 B4, a fitting is known which, for fastening an angled drive rod fitting component, provides a locking element on one leg that can pass through the edge strip in the rebate groove. The locking element can be moved along the rebate groove. A displacement body can assume an assembly position and an operating position by moving the locking element. In the assembly position, the locking element can be unlocked, and in the operating position, it is locked. The drive rod component can thus be assembled and disassembled without tools. This design is not reliable under high loads.

[0010] Therefore, there is a need for a fastening system that allows for tool-free assembly while ensuring secure attachment to both edge strips.

[0011] To solve this problem, the invention provides that, in a device according to the preamble, the plate has two parallel side edges, each terminating at right-angled transverse edges of the narrow sides. These transverse edges open into recesses inclined to the side edges and the transverse edges. A bore is provided in the transition area of ​​a recess to the side edge. The plate sits in a shallow pocket of the housing. The pocket is open on both sides of the housing and has two stop edges inclined to the longitudinal edges of the housing. The housing supports a slider that is movable along the housing. This slider engages the plate and moves it within the pocket so that the plate abuts the stop edges and is pivoted until the longitudinal edges are perpendicular to the side edges.The plate can be made of a high-strength material and bears a large surface area against the underside of the edge strips, securely anchoring the housing perpendicular to the groove. At the same time, the plate and the housing securely support the drive rod component perpendicular to the rebate groove.

[0012] It is intended that the drive rod fitting component is designed as a corner deflection with an angled housing.

[0013] To maximize the transmissible forces, the slide is mounted on a first leg of the housing, and a rear gripping edge is attached on one side of a longitudinal edge of the second leg.

[0014] Because the housing has a support strip that rests on the edge strip when the housing is mounted, the housing is also securely fixed perpendicular to the rebate groove.

[0015] The plate is designed to have a bore for the engagement of a slide pin. This creates coupling elements that are easy to manufacture. To ensure a simple slide design, it is designed to have a U-shaped cross-section and engage with guide ribs in guide grooves of the housing.

[0016] To ensure secure mounting of the disc, the guide grooves are provided on both sides of the housing.

[0017] To secure the end positions of the slide, it is provided that the slide and the housing can be locked against each other in an assembly position and an operating position, at least via a locking device.

[0018] Further advantageous designs can be seen in the drawings. They show:

[0019] Fig. 1 shows an angled drive rod fitting component in a first view, Fig. 2 shows the angled drive rod fitting component according to Fig. 1 in a second view, Fig. 3 shows a section through a profile bar with a drive rod fitting component mounted therein in a joining position,

[0020] Fig. 4 shows a section through a profile bar with a drive rod fitting component mounted therein in an operating position,

[0021] Fig. 5 shows a section along line VV in Fig. 3 without the airfoil profile, Fig. 6 shows a view along arrow VI in Fig. 3 without the airfoil profile, Fig. 7 shows a section along line VII-VII in Fig. 4 without the airfoil profile, Fig. 8 shows a view along arrow VIII in Fig. 4 without the airfoil profile, and Fig. 9 shows a section along line IX in Fig. 2 with the airfoil profile.

[0022] In Fig. 1, the connecting rod fitting is designated by reference numeral 1. The connecting rod fitting 1 is a corner drive with an angled housing 2. The housing 2 has a first leg 3 and a second leg 4.

[0023] A connecting rod 5, 6 is guided longitudinally on each leg 3, 4 and coupled to adjacent connecting rod components (not shown here). The connecting rod fitting component 1 is designed as a corner deflection for the movement deflection of the adjacent connecting rod components and therefore has a deflection channel 7 in which flexible deflection bands 8 (Figs. 3, 4) are guided. The connecting rods 5, 6 are equipped with coupling elements for coupling with adjacent connecting rod elements.

[0024] A pocket 9 is attached to leg 3 in the housing 2. A rear gripping edge 10 in the form of a strip is attached to leg 4. Figures 3 and 4 show an installation situation in the joining and operating positions of the drive rod component 1 on a profile bar 11. The profile bar 11 is part of a window or door sash. Two profile bars attached at right angles to each other form a right angle of the sash. The profile bar 11 has a groove 12. The drive rod fitting component 1 can be secured in the groove 12 of the window or door sash by a clamping device 13. The clamping device 13 comprises, firstly, the housing 2 in which the clamping device 13 is mounted. The housing 2 also serves to guide the drive rods 5, 6.

[0025] As shown in Figures 3 and 4, the housing 2 is equipped with a foot 14. The foot 14 rests on the base of the groove 15 and has a width that is less than the clear distance 16 between the corresponding edge ribs 17, 18 of the groove 12.

[0026] In the exemplary embodiment, the clamping device 13 further comprises an adjustable clamping element 19. In a first inactive position (Fig. 3), the clamping element 19 is recessed behind the longitudinal edge 20 of the housing 2 and has an effective width that is less than the distance 16. Therefore, the clamping element 19 does not project beyond the foot 14. This position is the joining position. In a second active position, the operating position, the clamping element 19 projects in front of the longitudinal edges 20, 21 of the housing 2. The clamping element 19 engages behind the edge ribs 17, 18, as shown in Fig. 4, and projects into the rear engagement area 22, 23. The rear engagement area 22 and 23 lies between the groove base 15, the edge ribs 17, 18, and the groove side walls 24, 25.

[0027] The clamping element 19 is a plate 26 pivotally mounted in the housing 2. The plate 26 is visible in Fig. 5. The plate 26 is almost hexagonal and has two parallel side edges 27, 28, each terminating at right-angled transverse edges 29, 30 of the narrow sides, which open into recesses 31, 32 inclined to the side edges 27, 28 and the transverse edges 29, 30. A bore 34 is provided in the transition area 33 of the recess 32 to the side edge 28. The bore 34 is open at its edge.

[0028] Fig. 6, which shows the assembly position with the housing 2 uncut, shows that the plate 26 does not protrude beyond the longitudinal edges 20, 21 of the housing 2 due to the clearances 31, 32 in the assembly position. Fig. 6 shows a section of the top view of the leg 3. The housing 2 forms a recess 35 for the slide 36, so that the slide does not protrude beyond the housing 2 or only does so minimally.

[0029] The pocket 9 is open on both sides of the housing 2 and has two stop edges 37, 38 inclined to the longitudinal edges 20, 21 of the housing 2. The stop edges 37, 38 terminate in edges 39, 40 perpendicular to the longitudinal edges 20, 21. The plate 26 sits in the flat pocket 9 of the housing 2 below the slider 36, as illustrated in Figures 3 and 4.

[0030] The housing 2 supports the slide 36, which is movable along the leg 3 of the housing 2. For this purpose, the housing 2 has two guide grooves 41, 42. The slide 36 engages in the guide grooves 41, 42 with its legs 43, 44. Leg 43 is longer. A guide rib 45, 46 is provided at the free end of each leg 43, 44. The slide 36 engages in the bore 34 of the plate 26 with a pin 47. The pin 47 is rotatably mounted in the bore 34. The pin 47 is designed as a detent pin and engages in the bore 34. It is therefore advantageous that the slide 36 be made of a material with spring-like properties. Because the slide 36 has an egg-shaped cross-section and engages with the guide webs 45, 46 in the guide grooves 41, 42 of the housing 2, and the guide webs 45, 46 are shorter than the guide grooves 41, 42, the slide 36 can be moved along the leg 3.

[0031] High actuation forces can act on the drive rod fitting component 1, which can cause the drive rod fitting component 1 to be unintentionally displaced relative to the sash and the profile bar 11. To maximize the transmissible forces, the slider 36 is mounted on the first leg 3 of the housing 2, and the rear grip edge 10 is attached to one side of the second leg 4 along a longitudinal edge. Furthermore, support strips 48, 49, 50 are provided on the housing 2, which rest on the edge strip web 17 when the housing 2 is mounted. These strips additionally secure the housing 2 perpendicular to the groove.

[0032] This results in the following effect: In the delivered state, the slider 36 is shifted to the left end position shown in Figures 5 and 6. It is advantageous for the slider 36 to be fixed in this position to ensure the correct alignment of the panel 26. The drive rod fitting 1 is brought to the sash corner, which consists of two profile bars 11 and 51 running at right angles to each other. The drive rod fitting 1 is inserted under the edge strip 52 of the second profile bar 51 by a pivoting movement with its rear gripping edge 10. An alignment movement of the leg 3 along the groove 12 causes the leg 4 to assume the position shown in Figure 9, with the edge strip 52 lying between the rear gripping edge 10 and the support strip 53. The pivoting movement is completed when the system strip 54 rests on the edge strip web 55.The drive rod fitting component 1 is guided slidably in the groove 56 by this engagement and can now be moved until the leg 3 enters the groove 12 and the housing 2 encompasses the corner area of ​​the sash corner. When the leg 3 comes to rest against the groove base 15 and / or the support strip 48 comes to rest against the edge strip web 17 (Fig. 3), the alignment is complete.

[0033] The fastening of the connecting rod fitting component 1 can be completed by actuating the slide 26. Starting from Fig. 5, the plate 26 is moved along with the edge 39 by a displacement of the slide 36. The eccentric arrangement of the pin 47 relative to the tip 57 causes the plate 26 to pivot about the tip 57. The plate 26 pivots in the pocket 9 without a fixed cylindrical axis of rotation existing between the plate 26 and the housing 2.

[0034] The movement of the plate 26 within the pocket 9 occurs exclusively during assembly and, if necessary, disassembly, so that the plate 26 either abuts the stop edge 39 or 40 in the operating position and is pivoted against it until the longitudinal edges 37, 38 are perpendicular to the side edges 27, 28, or, in the joining position, rests against the inner edges 58, 59. The recess, by its design, forms a pivot bearing.

[0035] Fig. 8 shows that in the operating position the plate 26 protrudes laterally beyond the housing 2.

[0036] Figures 6 and 8 show that the slide 36 has a tongue 60. In its operating position, the tongue 60 engages in a detent recess 61 within the housing 2. The tongue 60 is provided on its underside with a detent hook that engages in the detent recess 61 when the slide 36 is moved into its operating position.
