[0001] Device for coupling a sliding fitting component

[0002] Description

[0003] The invention relates to a device for coupling a sliding fitting component of a sliding sash of a window or door to a drive rod fitting provided for locking the sash.

[0004] Windows with sliding sashes must be able to be locked in a frame like pivoting sashes and in practice have additional sliding hardware components, such as a carriage, stays or center butt locks.

[0005] To connect such a sliding fitting component to the connecting rod fitting, a device is known, for example, from EP 3 018 275 A1, in which two components have transverse toothing. However, such components are complex to install.

[0006] EP 2 712 991 A1 discloses a connection mechanism with multiple bearing points. One end of the connection mechanism can be coupled to a drive rod, while the other end can be connected to a carriage. However, this makes the coupling very complex in terms of construction.

[0007] The invention is based on the problem of designing a device of the type mentioned at the outset in such a way that it enables a particularly simple coupling of the sliding fitting component to a drive rod fitting.

[0008] This problem is solved according to the invention in that a rigid coupling rod is slidably guided in the intended installation position parallel to a drive rod of the drive rod fitting, and that the coupling rod has means for connecting to the drive rod and means for connecting to a control pin of the sliding fitting component. This design enables the coupling rod to form a direct bridge between the drive rod and the control pin of the sliding fitting assembly. This makes the device particularly structurally simple. Only a few components need to be connected for assembly, so that the device enables particularly simple coupling of the sliding fitting component to the drive rod fitting.

[0009] According to another advantageous development of the invention, the means for connecting the coupling rod to the sliding fitting component is particularly simple in design if the control pin of the sliding fitting component is fastened in the coupling rod. The coupling rod preferably has a bore into which the control pin is pressed. Because the coupling rod is already connected to the control pin of the sliding fitting component, only the coupling rod needs to be connected to the connecting rod fitting for assembly. This device enables particularly simple coupling of the sliding fitting component to the connecting rod fitting.

[0010] In practice, espagnolette fittings control locks that lock the sash. These locks often have pins attached to the espagnolette. According to another advantageous development of the invention, the means for positively connecting the coupling rod to the espagnolette are particularly simple in design if the coupling rod has a coupling element for connection to a pin attached to the espagnolette.

[0011] According to another advantageous development of the invention, it contributes to simplifying the coupling of the components if the coupling element has a recess for inserting the pin.

[0012] According to another advantageous embodiment of the invention, the coupling element is highly stable and allows the pin to be engaged behind it if the coupling element has a bracket that extends over the recess. A positive connection between the coupling and the pin of the connecting rod fitting can be easily achieved according to another advantageous embodiment of the invention if the coupling element has a fixing element that can be moved over the recess.

[0013] According to another advantageous development of the invention, the fixing element is pivotably mounted on the coupling rod to further simplify the coupling.

[0014] According to another advantageous development of the invention, a particularly precise movement of the fixing element can be ensured if the coupling rod has a guide slot and if the fixing element penetrates the guide slot with a guide pin.

[0015] According to another advantageous development of the invention, different positions of the fixing element can be easily locked if the link has notches for the force-locking holding of the guide pin.

[0016] According to another advantageous development of the invention, movement of the fixing element into different positions is particularly simple if the fixing element has a handle.

[0017] According to another advantageous development of the invention, the sliding fitting component enables a simple movement of the sash when the drive rod fitting is actuated when the control pin penetrates into a stop slot of an actuating body of the sliding fitting component.

[0018] According to another advantageous embodiment of the invention, a basic adjustment of the sliding fitting component can be easily achieved if the control pin is designed to be eccentrically adjustable in the stop slot of the adjusting body. According to another advantageous embodiment of the invention, the eccentric adjustability of the control pin is particularly simple if the control pin has a rivet head with a round cross-section and if the rivet head is held force-fittingly in a bore of the coupling rod. Preferably, the control pin also has a recess for attaching an adjusting tool, such as a screwdriver or the like.

[0019] According to another advantageous embodiment of the invention, particularly low-friction movement of the sliding fitting component can be easily ensured if the control pin has a bearing ring that rolls in the stop slot. Preferably, the bearing ring has a plain bearing on the control pin.

[0035] Figure 1 shows a sliding window with a sash 2 that can be parked on a frame 1 and moved relative to it, in a sliding position in which the sash 2 is parked on the frame 1 and can be moved relative to it. On its lower side, the sliding window has two sliding fitting components designed as carriages 4, 5, guided on a guide rail 3, and on its upper side, two displaceably guided stays 6, 7, designed, for example, as tilt stays. Furthermore, the sliding window has a schematically illustrated connecting rod fitting 8 with a connecting rod 10 that can be moved longitudinally by a handle 9 for locking the sash 2 in the frame 1.

[0036] Figure 2 shows an enlarged perspective view of one of the carriages 4 from Figure 1. The carriage 4 has a base 11 and a bearing unit 12 with two rollers 13, 14. The base 11 has a base body 15 intended for screwing to the leaf 2. An adjusting body 16 coupled to the bearing unit 12 is also arranged in the base body 15. The carriage 4 has an adjusting device 17 for adjusting the height of the base body 15 relative to the rollers 13, 14. The bearing unit 12 has a bearing body 18 for directly supporting the rollers 13, 14 and a guide body 19. The bearing body 18 has sliding bodies 20 on its side facing away from the rollers for lateral support on the guide rail 3 shown schematically in Figure 1. The running direction of the carriage 4 is marked with a double arrow in Figure 2.

[0037] The adjustment device 17 has a slotted guide 21 arranged in the guide body 19 with an inclined slotted guide 22. A pin 23 of the adjusting body 16 penetrates the inclined slotted guide 22. The guide body 19 also has elongated holes 24 facing in the running direction of the carriage 4 for bearing axes 25 of the rollers 13, 14. An adjusting screw 26 of the adjustment device 17 serves to adjust the bearing body 18 relative to the guide body 19. When the adjusting screw 26 is turned, the bearing body 18 with the rollers 13, 14 moves relative to the guide body 19. The pin 23 of the adjusting body 16 slides in the slotted guide 22 and adjusts the distance between the rollers 13, 14 and the adjusting body 16.

[0038] The guide body 19 has two parallel guide plates 27, 28. The guide plates 27, 28 are connected to each other by a cross member 29. The adjusting screw 26 of the adjustment device 17 is screwed into the cross member 29 and is supported on the bearing body 18.

[0039] A coupling rod 30, which is guided longitudinally displaceably in the base body 15, serves for the connection to the drive rod 10 of the drive rod fitting 8 from Figure 1. One end of the drive rod fitting 8 is shown schematically in Figure 2. The connection of the coupling rod 30 to the drive rod 10 is explained in more detail in Figures 10 and 11. For this purpose, the coupling rod 30 has a coupling element 31 designed to complement a conventional locking pin of the drive rod fitting 8 fastened to the drive rod 10. The coupling rod 30 has a control pin 32 with which it penetrates into a longitudinal guide 33 of the base body 15, shown in Figures 3 and 7, and into a stop link 34 of the adjusting body 16, shown in Figures 3 and 6. The base body 15 has a guide 35 for the adjusting body 16, which guides transversely to the running direction of the carriage 4.

[0040] Figure 3 shows a sectional view through the area of ​​the carriage 4 from Figure 2 containing the base, taken along line III-III. To simplify the drawing, the area of ​​the carriage 4 containing the bearing unit 12 is not shown in section. The control pin 32 fastened to the coupling rod 30 has a bearing ring 36 guided in the longitudinal guide 33 of the base body 15 and a further bearing ring 37 guided in the stop link 34 of the adjusting body 16. The bearing rings 36, 37 are arranged eccentrically to one another and rotatably mounted on the control pin 32. By rotating the control pin 32 in the coupling rod 30, its eccentricity can be adjusted and thus the base body 15 can be moved perpendicular to the plane of the drawing. The shape of the stop link 34 is shown in Figure 6.When the coupling rod 30 is moved by driving the drive rod 10, the control pin 32 is moved in the stop link 34, thus adjusting the actuating body 16 relative to the base body 15 perpendicular to the plane of the drawing. This also causes the leaf 2 shown in Figure 1 to be moved into the sliding position in its plane relative to the frame 1 or pulled against the frame 1 into a locking position.

[0041] For clarity, Figure 4 shows a cross-sectional view of the carriage 4 from Figure 3 along line IV-IV. The cross-section is taken through the pin 23 of the adjusting body 16. It can be seen that the pin 23 is made in one piece with the adjusting body 16. The sliding body 20 connects two bearing plates 38, 39 of the bearing body 18 to each other in a form-fitting manner.

[0042] Figure 5 shows a sectional view through the carriage 4 from Figure 3 along the line V-V in the area of ​​the control pin 32. In the position shown, the carriage 4 is in a position in which the sash 2 from Figure 1 can be displaced relative to the frame. For this purpose, the sash 2 is positioned away from the frame 1, and the control pin 32 is arranged in an end position of the stop link 34 of the actuating body 16. The control pin 32 is supported in the longitudinal guide 33 of the base body 15.

[0043] Figure 6 shows the actuating body 16 in an enlarged perspective view. The stop link 34 is open toward the side of the base body 15 to accommodate the control pin 32. The actuating body 16 has guide webs 40, 41, which, when assembled, penetrate into the guide 35 of the base body 15. In addition to the stop link 34, the actuating body 16 has several sliding elements 42. The sliding elements 42 project beyond the surface of the actuating body 16 and, when assembled, are supported on the base body 15. The stop link 34 is S-shaped.

[0044] Figure 7 shows the base body 15 in an enlarged perspective view with the guide 35 spanning the guide webs 40, 41 of the actuating body 16. The base body 15 also has an elongated receptacle 43 for the coupling rod 30 with projections 44 spanning the receptacle 43 for the longitudinal guidance of the coupling rod 30.

[0045] Figure 8 shows the components of the carriage 4 prior to assembly. The bearing plates 38, 39 of the bearing body 18 are connected to each other via a support element 45. In the assembled state, the adjusting screw 26 of the adjusting device 17 is held by a constriction 46 in a bore 47 of the support element 45. The bearing body 18 also has a vertical elongated hole 48 through which the pin 23 of the adjusting body 16 is guided into the slotted guide 22 of the guide body 19.

[0046] The control pin 32 has a rivet head 49, with which it is riveted into a bore 50 of the coupling rod 30. At least one of the bearing rings 36, 37 is arranged eccentrically to the rivet head 49. At its end facing away from the rivet head 49, the control pin 32 has an adjustment recess (not shown) for its rotation in the bore 50 of the coupling rod 30. The adjustment recess can be a conventional internal spline or a slot for a screwdriver. Figure 9 shows the coupling rod 30 in a further perspective view. The coupling element 31 of the coupling rod 30 has a recess 51 with a bracket 52 that extends over an edge of the recess 51. This recess 51 serves to receive and engage behind a pin 53 of the drive rod 10, shown in Figure 10.

[0047] Figure 10 shows a partial section through the coupling rod 30 in the area of ​​the coupling element 31 after a connection with the drive rod 10 of the drive rod fitting 8 provided for locking the sash 2 in the frame 1 from Figure 1. The drive rod fitting 8 has a faceplate 54, on which the drive rod 10 is guided for longitudinal displacement, and the pin 53 fastened to the drive rod 10. The pin 53 has a radially widening mushroom head 55. The pin 53 engages over a partial area of ​​the coupling rod 30 and thus creates a positive connection with the coupling rod 30 in the direction of movement of the drive rod 10. The pin 53 can, for example, be a conventional locking pin which is used in conventional locks (not shown).

[0048] Figure 11 shows a partial section through a further embodiment of a coupling rod 130 after connection to the drive rod 10 of the drive rod fitting 8. A coupling element 131 of the coupling rod 130 has a fixing element 156 for supporting a mushroom head 155 of a pin 153 fastened to the drive rod 10.

[0049] Figures 12 and 13 show the coupling rod 130 from Figure 11 in a perspective view. As in the previous embodiment, the coupling rod 130 has a bore 150 for the control pin shown, for example, in Figure 8. It can be seen that the fixing element 156 is pivotally mounted on the coupling rod 130 by a bearing axis 157 and has a guide pin 158. The guide pin penetrates the coupling rod 13 in a slotted guide 159 that is guided in an arc around the bearing axis 157. The slotted guide 159 has notches 160 for holding the guide pin 158 in various positions. In a position of the fixing element 156 pivoted away from a recess 151 for the pin 153, the coupling rod 130 can be mounted on the pin 153 of the drive rod 10 from Figure 11.In the illustrated position of the fixing element 156 pivoted into the recess, the pin 153 is positively connected to the coupling rod 130, as shown in Figure 11. Furthermore, the fixing element 156 has a handle 161 for movement between the different positions.
