Description

[0001] manual The present invention relates to an accessory for sliding tilt windows or doors for moving a sash body relative to a frame, the accessory having a frame-side accessory component for fixing to the frame, a sash-side accessory component for fixing to the sash body, a scissor-type extender connecting these accessory components, a retaining arm of the scissor-type extender supported at the two accessory components, and a control arm of the scissor-type extender supported at the retaining arm, wherein the ends of the retaining arm and the control arm opposite to the retaining arm are pivotally supported at a longitudinally slidable slider, and having a groove arranged in the slider to receive a control pin in a closed position, a hinged position, and a tilted position, wherein the groove has a longitudinal portion and a curved portion extending from the longitudinal portion.

[0002] For example, a fitting for a sliding tilt window is known from WO 2017 / 140573 A1. In this fitting, the control arm has a control arm guide groove in which a guide pin is guided. The control arm guide groove has a curved portion in which the guide pin is retained when in the casement position. The fixed control element has a movable guide member with a guide groove for receiving a control pin fixed to the control arm.

[0003] A fitting is known from WO 2015 / 003872 A1, wherein a pin inserted into a groove restricts the movement of a control pin within the groove. An actuating element connected to a scissor-type unfolding component makes it possible to reposition the pin when the fan body is tilted, thereby enabling a greater movement distance of the control pin and allowing the fan body to swing linearly to the tilted position.

[0004] An accessory is known from DE 20 2008 004 933 U1, in which a control arm has a control groove. The control groove is traversed by a guide bolt of a sliding support.

[0005] The present invention is based on the problem of improving the above-mentioned type of accessories so that they are constructed in a particularly compact manner and reliably avoid functional failure.

[0006] The present invention solves this problem by having a locking slider that is elastically preloaded toward the curved portion, and the locking slider supports a control pin located within the curved portion.

[0007] With this design, the locking slider and the slide are arranged on the same component. This reduces the accumulation of tolerances between different components, thus avoiding potential sources of failure that could lead to malfunction. Furthermore, the locking slider is guided directly at the sliding element. As a result, the fitting is designed to be particularly compact.

[0008] According to another advantageous improvement of the invention, if the control pin of the control arm is arranged within the curved portion when in the open position and within the longitudinal portion when in the inclined position, different positions of the accessory can be easily approximated. When the fan body is displaced, the accessory is in the open position. Due to the invention, when the fan body is displaced, the control pin is supported by the locking slider within the curved portion, thereby reliably holding the fan body in its position when displaced.

[0009] According to another advantageous improvement of the invention, if a second scissor-shaped unfolding member is supported at the sliding member, wherein the second scissor-shaped unfolding member has a locking device for securing the second scissor-shaped unfolding member in an inclined position, then the various positions of the fan body can be easily locked. This contributes to the ease of operation of the accessory, because the fan body can be locked in all positions by means of the two scissor-shaped unfolding members.

[0010] According to another advantageous improvement of the invention, the end stop design of the guide rail is particularly simple if the accessory component having the slider has a fixed stop buffer block for supporting the slider. The stop buffer block supports the slider when in the tilted position, thereby reliably holding the fan body in its position when tilted. This contributes to further improved safety in case of malfunction.

[0011] According to another advantageous improvement of the invention, if the locking slider is preloaded by a locking spring and has an inclined ramp to support the control pin within the curved portion, it helps to further improve the ease of operation of the accessory.

[0012] According to another advantageous improvement of the invention, if the accessory component with the groove has a fixed control unit, and if the control unit has a control tip that extends into the range of motion of the control pin, the process of controlling the control pin according to the position of the slider is designed to be particularly simple.

[0013] According to another advantageous improvement of the invention, if the control tip has a guide ramp, and if the guide ramp slopes from the longitudinal portion to the curved portion, the control pin can overcome the retaining force of the locking slider and move out of the curved portion. Since the control unit is fixed, contact between the guide ramp and the control pin can only occur at the end position during sector displacement; therefore, pushing the control pin out of the curved portion is only feasible at the end position of the slider.

[0014] According to another advantageous improvement of the invention, if the inclination of the guide slope of the control tip relative to the longitudinal portion of the groove is shallower than the inclination of the ramp of the locking slider, then the design of removing the support of the locking slider for the control pin is particularly easy.

[0015] According to another advantageous improvement of the invention, if the control unit has a control slider with a control tip preloaded by a control spring, the control pin is guided within the control unit between the tilt position and the closed position. This further reduces friction between the end positions of the control pin in the tilt position and the closed position.

[0016] According to another advantageous improvement of the invention, the process of removing the control pin from the bent portion is designed to be particularly reliable if the preload of the control slider is greater than the preload of the locking slider.

[0017] According to another advantageous improvement of the invention, if the slider has a reinforcing member, and if the reinforcing member has a groove profile, the control pin is reliably supported in each position. Simultaneously, the reinforcing member enables height compensation of the locking slider.

[0018] According to another advantageous improvement of the invention, if the control pin has a large-diameter support shoulder at the height of the reinforcing rib of the control arm, followed by a small-diameter guide shoulder at least at the height of the slide groove, and subsequently a large-diameter control shoulder at the height of the control tip, it helps to further reduce the risk of functional failure. The reinforcing rib and support shoulder ensure high stability of the component connection. The control shoulder engages with the slide groove from the rear, thereby axially fixing the component in its position.

[0019] According to another advantageous improvement of the invention, if the control pin is designed as the bearing axis of the control arm, the fitting is designed to be particularly simple in structure.

[0020] According to another advantageous improvement of the invention, if the fan-side fitting component is connected to the cover plate, and if the cover plate has a support bar that engages the free end of the retaining arm from above, the locking design of the end of the retaining arm supported at the fan-side fitting component in the vertical position is particularly simple.

[0021] This invention allows for many implementations. One such implementation is shown in the accompanying drawings to further illustrate its basic principles, and will be described below. In the drawings: Figure 1 Showing a double-pane sliding tilt window with fittings; Figure 2 The diagram is shown schematically by means of a slightly enlarged view. Figure 1 The accessories shown are for the sliding and tilting window; Figure 3 A top-down view magnified to show the view in the open position. Figure 2 The scissor-shaped unfolded part of the accessory shown; Figure 4 The view from below shows the position when it is in the open position. Figure 3 The scissor-shaped unfolded component shown; Figure 5 Show Figure 4 The shown is a cross-sectional view of the component along line VV; Figure 6 Showing when in an inclined position Figure 4 The accessories shown; Figure 7 When in the closed position Figure 4 The accessories shown; Figure 8 Enlarged view of the passage along line VIII-VIII Figure 1 The diagram shows a cross-sectional view of a portion of a sliding tilt window with fittings.

[0022] Figure 1 A double-sash sliding tilt window is shown, comprising a frame 1, movable sashes 2, and a fitting 3. The fitting 3 is used to move the sashes 2 relative to the frame 1 between a closed position, a level position, and a tilted position. Figure 1 In the case of the fan body 2, when it is in the open position, the plane of the displaceable fan body 2 is away from the frame 1 and can be displaced relative to the frame 1.

[0023] Figure 2 Show Figure 1 The upper left portion of the sliding tilt window is shown. The sliding tilt window has a drive lever fitting 4, which has a locking pin 5 that can be displaced at the sash 2 and a locking plate 6 fixed to the frame 1 for locking the sash 2 in the frame 1 when in the closed position. For simplicity, the frame 1 and sash 2 are shown with dashed lines, and only a corner area of ​​the drive lever fitting 4 is shown.

[0024] Accessory 3 has a frame-side accessory component 7, which has a slider 8 guided longitudinally at the frame 1 and a fan-side accessory component 9. Two scissor-mounted unfolding components 10 and 11 connect accessory components 7 and 9. Accessory 3 is in a flat-open position, in which the fan 2 is offset parallel to the frame 1 with its plane. In this position, the fan 2 can be displaced relative to the frame 1, wherein the slider 8 slides along the frame 1 within the frame-side accessory component 7. One of the scissor-mounted unfolding components 10 is connected to a control unit 12 to control the fan 2 to enter different positions. The other scissor-mounted unfolding component 11 has a locking device (not shown in detail) for locking it in various positions.

[0025] Figure 3A magnified view shows the scissor-type deployable member 10 connected to the control unit 12. The scissor-type deployable member 10 has a retaining arm 13 supported at the slider 8 and the fan-side accessory component 9. One end of the control arm 14 is supported at the retaining arm 13, and the other end is guided in a slide 16 via a control pin 15. The slide 16 has a longitudinal portion 17 and a curved portion 18. An extension 19 located at the free end of the longitudinal portion 17 acts as an assembly aid for the control pin 15. When in the shown open position, the control pin 15 is held within the curved portion 18 and supported thereby by a locking slider 20. The control unit 12 has a cover plate 21 fixedly connected to the frame 1. When in the shown open position, the displaceable slider 8 is capable of displacement relative to the fixed control unit 12.

[0026] Figure 4 Shown through the opposite view seen from below Figure 2 The scissor-shaped deployable member 10 is shown connected to the control unit 12. Figure 4 In the diagram, control arm 14 is indicated only by dashed lines to show the components below it. Locking slider 20 is disposed at slide member 8 and preloaded by locking spring 22 in the direction of slide groove 16. The ramp 23 of locking slider 20, inclined towards the longitudinal portion 17, elastically supports control pin 15 in the bent portion 18.

[0027] The control unit 12 has a control slider 24 that is guided longitudinally at the cover plate 21. The control slider 24 is preloaded by a control spring 25 to the illustrated end position, where, when the slider 8 slides, the control tip 26 extends into the range of motion of the control pin 15. The control tip 26 has a guide ramp 27 that slopes from the height of the longitudinal portion 17 of the groove 16 toward the curved portion 18. Comparing the guide ramp 27 of the control tip 26 with the ramp 23 of the locking slider 24, it can be seen that the slope angle of the guide ramp 27 is shallower. Furthermore, the preload of the control slider 24 is greater than the preload of the locking slider 20.

[0028] Figure 5 Showing the passage along the VV line Figure 3The diagram shows a cross-sectional view of the scissor-shaped unfolded member 10 with control unit 12. It can be seen that a stop buffer block 28, designed as a rubber buffer block, is arranged at control unit 12. The slider 8 has a stop 29 opposite to the stop buffer block 28. Furthermore, the slider 8 has a plastic reinforcing member 30 at the slide groove 16. The control pin 15 is supported in the reinforcing rib 31 of the control arm 14 by a large-diameter support shoulder 32 and has a small-diameter guide shoulder 33 through which the control pin passes through the reinforcing member 30 and the slide groove 16. The locking slider 20 also supports the control pin 15 at the small-diameter guide shoulder 33. The control shoulder 34, located at the free end of the control pin 15, is at the height of the control slider 24.

[0029] from Figure 4 Starting from the open position shown, as the slider 8, along with its control pin 15 located in the curved portion 18, displaces into the control unit 12, the control pin 15 reaches the guide ramp 27. As described above, because the preload of the control slider 24 is greater than the preload of the locking slider 20, and the inclination of the guide ramp 27 is shallower than the inclination of the ramp 23 of the locking slider 20, the control pin 15 is pushed out of the curved portion 18. This position is as follows... Figure 6 As shown, this indicates the tilt position.

[0030] When in Figure 6 In the tilted position shown, the control pin 15 is located in the longitudinal portion 17 of the slide groove 16 and is held within this longitudinal portion by the guide ramp 27 of the control slider 24. When in the tilted position shown, the stop 29 of the slider 8 abuts against the stop buffer block 28. To indicate the position of the control slider 24, Figure 6 The cover plate 21 of the control unit 12 is not shown.

[0031] from Figure 6 Starting from the tilted position shown, when the fan body 2 with the fan body side fitting component 9 presses against the frame side fitting component 7 with the sliding member 8, the control pin 15 moves further away from the curved portion 18 in the longitudinal portion 17, as... Figure 7 As shown.

[0032] Figure 7 The accessory 3 is shown in the closed position, in which the fan body 2 can be accessed via... Figure 1 The drive lever assembly 4 shown is locked in the frame 1. The control pin 15 is held in place by the control slider 24 by its large-diameter control shoulder 34. To indicate the position of the control slider 24, Figure 7 The cover plate 21 of the control unit 12 is not shown.

[0033] Figure 8 It shows the passage along line VIII-VIII Figure 1The diagram shows a cross-sectional view of the upper portion of the sliding tilt window. The sash-side fitting component 9 has bearing bolts 35 for retaining the free end of the arm 13 and bearing blocks 36 connected to the sash 2. Furthermore, it can be seen that the slider 8 is guided perpendicularly to the plane of the drawing within the frame-side fitting component 7. Parts of the sash-side fitting component 9 and the frame-side fitting component 7 are arranged below the cover plate 37.

[0034] The cover plate 37 is designed to be elongated and extend perpendicular to the drawing plane. Two latches 38 and 39 of the cover plate 37 lock with the fan-side fitting component 9. Furthermore, the cover plate 37 has a skirt 40 extending from the upper latches 39. A support bar 41 extends from the central area of ​​the skirt 40, passing over the free end of the retaining arm 13. The support bar 41 extends to the front of the bearing bolt 35 and secures the retaining arm 13, preventing displacement in the axial direction of the bearing bolt 35. Thus, the free end of the retaining arm 13 is held between the support bar 41 and the bearing block 36, thereby securing it in the axial direction of the bearing assembly 42 formed by the bearing bolt 35 with the retaining arm 13. For clarity, the axis of the bearing bolt 35 is indicated by a dashed line. The cover plate 37 is integrally manufactured from plastic using an injection molding process.
