[0001] Fittings for a sliding-tilt window

[0002] Description

[0003] The invention relates to a fitting for a sliding-tilt window or door for moving a sash into the closed position, the stored position and the tilted position relative to a frame, with a frame-side fitting part provided for fastening to the frame, with a sash-side fitting part provided for fastening to the sash, with a stay link connecting the fitting parts, with a holding arm of the stay link mounted on both fitting parts, with a control arm of the stay link mounted on the holding arm, wherein the sash-side fitting part is connected to a cover panel.

[0004] A fitting for a sliding door is known from EP 0 811 741 A2. In this fitting, the cover panel covers the technical components of the fitting. The cover panel extends up to a projection arm of the fitting, so that it is not visible when the sliding door is closed.

[0005] A fitting for a tilt-and-slide window is known, for example, from WO 2017 / 140573 A1. In this fitting, the control arm has a control arm guide slot in which a guide pin is guided. The control arm guide slot has a bent portion that holds the guide pin in the closed position. A fixed control element has a movable insertion part with an insertion slot for receiving a control pin attached to the control arm.

[0006] WO 2015 / 003872 A1 discloses a fitting in which a bolt penetrating the guide rail limits the movement of the control pin within the guide rail. An actuating element connected to the stay arm allows the bolt to be relocated when the sash is to be tilted, allowing greater movement of the control pin and thus allowing the sash to swing straight out into the tilt position.

[0007] DE 20 2008 004 933 U1 discloses a fitting in which the control arm has a control groove. A slidably mounted guide pin passes through the control groove. The invention is based on the problem of developing a fitting of the type mentioned above in such a way that visually disturbing technical components are concealed and that the fitting has as few components to be installed as possible.

[0008] This problem is solved according to the invention in that the cover panel has a support web which overlaps the free end of the holding arm and secures a bearing of the holding arm on the sash-side fitting part in the axial direction.

[0009] This design gives the cover panel a dual function. It conceals visually disruptive hardware components. Furthermore, the cover panel, together with the support bar, secures the free end of the retaining arm in the axial direction. Thanks to the invention, additional securing of the retaining arm in the axial direction to the sash-side hardware component is no longer necessary. This reduces the number of components required for assembly.

[0010] According to another advantageous development of the invention, the assembly of the cover panel is particularly simple if the cover panel has two locking hooks for connection to the sash-side fitting part.

[0011] According to another advantageous development of the invention, the cover panel is designed to be particularly simple in construction if the cover panel has an apron that leads away from the locking hooks and if the support web protrudes from the apron.

[0012] According to another advantageous development of the invention, an optical disturbance of technical components of the fitting when the sliding-tilting window is closed can be particularly reliably avoided if the apron covers at least a partial area of ​​the frame-side fitting part.

[0013] According to another advantageous embodiment of the invention, the cover panel can be manufactured particularly cost-effectively if it is made in one piece from plastic. An extrusion process or an injection molding process is suitable for manufacturing the cover panel.

[0014] The fitting could comprise various components for supporting and releasing the extension scissor. However, according to another advantageous development of the invention, the fitting has particularly few components to be installed if a slider is guided longitudinally displaceably in the frame-side fitting part and if a link for controlling the extension scissor between the positions has a longitudinal section and a bend extending away from the longitudinal section for accommodating a control pin of the extension scissor in the closed position. Furthermore, this design allows the technical components of the fitting to be arranged particularly easily under the cover panel.

[0015] According to another advantageous development of the invention, the fitting is particularly compact and can therefore be securely mounted under the cover panel if the link is arranged in the slider, if the control pin is arranged on the control arm and if the slider has a locking slide that is spring-loaded in the direction of the bend and the locking slide supports the control pin located in the bend.

[0016] To further reduce the number of fitting components, a second scissor stay is supported on the glider. The second scissor stay has locking mechanisms to hold it in the tilted position, and the cover plate with the support bar extends integrally over both scissors. This design allows the two scissors to perform different functions, thus avoiding components with a dual function. However, both scissors stays are secured by the support bar of one cover plate.

[0017] According to another advantageous development of the invention, control means for controlling the fitting are designed to be particularly compact and thus easy to mount under the cover panel if the fitting part having the link has a fixed control unit and if the control unit has a control tip projecting into the movement range of the control pin.

[0018] According to another advantageous development of the invention, the control unit contributes to simplifying the design of the fitting if it has a control slide with a control tip preloaded by a control spring. This also reduces friction of the control pin between the end positions of the tilt position and the locking position.

[0019] According to another advantageous development of the invention, the preload of the control slide is greater than the preload of the locking slide to further simplify the design of the fitting. This also contributes to a particularly small number of fitting components.

[0020] The invention permits numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and is described below. This shows in

[0022] Fig. 2 shows schematically the fitting of the sliding-tilt window from Figure 1 in a slightly enlarged view,

[0023] Fig.3 shows an enlarged plan view of a stay of the fitting from Figure 2 in the storage position,

[0025] Fig.5 is a sectional view of the fitting from Figure 4 along the line V - V,

[0026] Fig.6 the fitting from Figure 4 in a tilted position,

[0027] Fig.7 the fitting from Figure 4 in a closed position,

[0028] Fig.8 shows an enlarged sectional view through a portion of the sliding-tilt window with the fitting from Figure 1 along the line VIII - VIII.

[0029] Figure 1 shows a double-leaf slide-tilt window with a frame 1, a sliding sash 2 and a fitting 3. The fitting 3 is used to move the sash 2 between a closed position, a stored position and a tilted position relative to the frame 1. In Figure 1, the sliding sash 2 is with its plane away from the frame 1 in the stored position and can be moved relative to the frame 1.

[0030] Figure 2 shows an upper left section of the sliding-tilt window from Figure 1. The sliding-tilt window has a connecting rod fitting 4 with a locking pin 5 that can be moved on the sash 2 and a strike plate 6 attached to the frame 1 for locking the sash 2 in the closed position. To simplify the drawing, the frame 1 and the sash 2 are shown in dot-dashed lines, and only a corner section of the connecting rod fitting 4 is shown.

[0031] The fitting 3 has a frame-side fitting part 7 with a glider 8 that is guided longitudinally on the frame 1, and a sash-side fitting part 9. Two projection scissors 10, 11 connect the fitting parts 7, 9. The fitting 3 is in the stored position, in which the sash 2 is stored parallel to the frame 1 in its plane. In this position, the sash 2 can be moved relative to the frame 1, with the glider 8 in the frame-side fitting part 7 sliding along the frame 1. One of the projection scissors 10 is connected to a control unit 12 for controlling the sash 2 in the various positions. The other projection scissor 11 has locking means (not shown in detail) for locking it in the various positions.

[0032] Figure 3 shows an enlarged view of the extension scissor 10 connected to the control unit 12. The extension scissor 10 has a holding arm 13 mounted on the slider 8 and the sash-side fitting part 9. A control arm 14 is mounted at one end on the holding arm 13 and the other end is guided via a control pin 15 in a guide rail 16. The guide rail 16 has a longitudinal section 17 and an offset 18. An extension 19 located at the free end of the longitudinal section 17 serves as an assembly aid for the control pin 15. In the illustrated stored position, the control pin 15 is held in the offset 18 and is supported there by a locking slide 20. The control unit 12 has a cover plate 21 firmly connected to the frame 1. In the illustrated storage position, the movable slider 8 can be moved relative to the fixed control unit 12.

[0033] Figure 4 shows the extension scissors 10 from Figure 2, connected to the control unit 12, in a view from below. In Figure 4, the control arm 14 is shown only in dot-dash lines to illustrate the components underneath. The locking slide 20 is slidably mounted on the slider 8 and is biased toward the guide 16 by a locking spring 22. A ramp 23 of the locking slide 20, inclined toward the longitudinal section 17, resiliently supports the control pin 15 in the offset 18.

[0034] The control unit 12 has a control slide 24 guided longitudinally on the cover plate 21. The control slide 24 is preloaded by a control spring 25 into the illustrated end position, in which a control tip 26 protrudes into the range of motion of the control pin 15 when the slider 8 is moved. The control tip 26 has a guide bevel 27, which is inclined from the height of the longitudinal section 17 of the link 16 to the offset 18. A comparison of the guide bevel 27 of the control tip 26 to the ramp 23 of the locking slide 24 shows that the guide bevel 27 is more gently inclined. Furthermore, the preload of the control slide 24 is greater than the preload of the locking slide 20.

[0035] Figure 5 shows a sectional view through the extension scissors 10 with the control unit 12 from Figure 3 along line VV. It can be seen that a stop buffer 28 designed as a rubber buffer is arranged on the control unit 12. The slider 8 has a stop 29 opposite the stop buffer 28. Furthermore, the slider 8 has a plastic reinforcement part 30 on the guide 16. The control pin 15 is supported in a reinforcement bead 31 of the control arm 14 with a wide-diameter support shoulder 32 and has a small-diameter guide shoulder 33 with which it penetrates the reinforcement part 30 and the guide 16. The locking slide 20 also supports the control pin 15 on the small-diameter guide shoulder 33. A control shoulder 34 arranged at the free end of the control pin 15 is located at the height of the control slide 24.

[0036] When, starting from the storage position in Figure 4, the slider 8 with the control pin 15 located in the offset 18 is moved into the control unit 12, the control pin 15 comes into contact with the guide bevel 27. Since, as explained above, the preload of the control slide 24 is greater than the preload of the locking slide 20 and, moreover, the inclination of the guide bevel 27 is flatter than the ramp 23 of the locking slide 20, the control pin 15 is pressed out of the offset 18. This position is shown in Figure 6 and indicates the tilted position.

[0037] In the tilted position shown in Figure 6, the control pin 15 is located in the longitudinal section 17 of the guide 16 and is held in this longitudinal section by the guide bevel 27 of the control slide 24. In the tilted position shown, the slider 8 abuts the stop buffer 28 with its stop 29. To indicate the position of the control slide 24, the cover plate 21 of the control unit 12 is not shown in Figure 6.

[0038] When, starting from the tilt position shown in Figure 6, the sash 2 is pressed with the sash-side fitting part 9 against the frame-side fitting part 7 with the slider 8, the control pin 15 is moved further in the longitudinal section 17 away from the offset 18, as shown in Figure 7.

[0039] Figure 7 shows the fitting 3 in the closed position, in which the sash 2 can be locked in the frame 1 via the drive rod fitting 4 shown in Figure 1. The control pin 15 is held by the control slide 24 with its large-diameter control shoulder 34. To indicate the position of the control slide 24, the cover plate 21 of the control unit 12 is not shown in Figure 7.

[0040] Figure 8 shows a sectional view through the upper portion of the tilt-and-slide window from Figure 1 along line VIII-VIII. The sash-side fitting 9 has a bearing pin 35 for a free end of the retaining arm 13 and a bearing block 36 connected to the sash 2. Furthermore, it can be seen that the slider 8 is guided in the frame-side fitting 7 perpendicular to the plane of the drawing. The sash-side fitting 9 and a portion of the frame-side fitting 7 are arranged below a cover panel 37.

[0041] The cover panel 37 is elongated and extends perpendicular to the plane of the drawing. Two locking hooks 38, 39 of the cover panel 37 are locked to the sash-side fitting part 9. The cover panel 37 also has an apron 40 extending from the upper locking hook 39. From a central region of the apron 40, a support web 41 projects over the free end of the retaining arm 13. The support web 41 extends up to the bearing pin 35 and secures the retaining arm 13 against displacement in the axial direction of the bearing pin 35. As a result, the free end of the retaining arm 13 is held between the support web 41 and the bearing block 36 and thus secured in the axial direction of a bearing 42 formed by the bearing pin 35 and the retaining arm 13. For clarity, the axis of the bearing pin 35 is shown in dash-dotted lines. The cover panel 37 is made of one piece plastic using the injection molding process.
