EP3859110B1 - Sliding door fitting and method for moving a control device - Google Patents

Description

The present invention relates to a sliding door fitting for a sliding leaf according to the preamble of claim 1 and a method for moving a control device according to the preamble of claim 12.

The EP 3 321 459 B1 discloses a carriage for a sliding sash, in which a support part for fixing a sash is movable relative to a support part with rollers. As a result, a sliding sash can be moved from a closed position by moving the support part relative to the support part into a parallel position so that the carriage can then be moved along a running rail. Such a sliding door fitting has proven itself, but control devices for turning off or tightening the sliding leaf must be provided on several sides of the sliding leaf. Especially in the area of a center strut, where the sliding sash moves past when moving along the running rail in the opening or closing direction, there is no known control device for pushing off and tightening the sliding sash.

A control device for turning off the sliding sash can be integrated into the carriage, as shown in the DE 10 2014 220 837 B3 is revealed. However, the provision of a curve guide on the carriage weakens the support structure and contradicts the requirement for a compact design. In addition, other control devices and closure arrangements must be positioned very precisely.

The EP 2 682 545 B1 discloses a closure arrangement for a sliding door, in which a mushroom head is fixed to a cross slide, which engages in a receptacle of a closure element for locking. With such a closure element, locking can take place if the closure element and the mushroom head are precisely aligned, but no forces are transmitted to push off the sliding sash in order to move it from the closed position into the parallel position. As a result, corresponding control devices for turning off the sliding sash must be provided on other sides of the sliding sash, which leads to a large number of components that have to be assembled separately.

WO 2007/139355 discloses a sliding door fitting with the features of the preamble of claim 1 and an associated method.

It is therefore the object of the present invention to create a sliding door fitting for a sliding leaf and a method for moving a control device which is easy to install and by means of which a sliding leaf is better guided between the closed position and the parallel parked position.

This object is achieved with a sliding door fitting with the features of claim 1 and a method for moving a control device with the features of claim 12.

In the sliding door fitting according to the invention, at least one control device is provided for moving the sliding sash between the closed position and the parallel parked position, the at least one control device comprising a curved guide formed in a slide and a control element guided in the curved guide, the control element during the movement in the Curve guidance of the at least one control device from the closed position into the parallel parked position of the sliding sash passes through a maximum, so that the slide is first moved in a first direction and then in a second direction opposite to the first direction. As a result, the movement of the slide can be used to push the sliding sash from the closed position into the parallel parked position via the control device, with the section of the curve guide after the maximum being used to move the slide in the opposite direction in order to move the slide from the To lift off the contact surface to push off the sliding sash. This movement thus ensures that the slide or a component connected to the slide is spaced from a contact surface for pressing, so that the sliding sash can then be moved along the running rail without dragging. The opposite movement of the slide in the second direction is therefore not used to move the sliding sash from the parallel position back into the closing direction, but the opposite movement is used to move the slide or a component connected to the slide at a distance from the contact surface Arrange prints. This measure also allows control devices to be arranged in the area of a center strut, so that the sliding sash is better guided when parking or tightening. A center strut is arranged in a frame, which the sliding sash moves past when opening. A center strut can be a vertical strut between a lower strut and an upper strut of a frame, but also a strut of a frame of a fixed panel or another sliding sash.

According to the invention, the curve guide has a section rising up to the maximum and a section falling behind the maximum, on which the control element is guided. The terms "rising" and "falling" refer to a view when the maximum is the highest point of the curve between the closed position and the parallel parked position. The curve guide can of course be arranged anywhere in space, so that the highest point does not have to be aligned in the vertical direction, but only serves to explain the design of the curve guide, which forms a wave. The first section in the rising direction is preferably longer than the second section in the falling direction, in particular on the rising section the sliding sash can be pushed by, for example, 3 to 10 mm from the closed position into the parallel parked position, the slide being moved by moving the Control element on the sloping section between 0.2 mm to 3 mm, in particular 0.5 mm to 2 mm, is moved in the opposite direction in order to be removed from a contact surface for pushing off the sliding sash. The control element can preferably be moved via a rotatable handle element that can be moved between two end positions.

The control element moves between the closed position and the parallel position of the sliding sash, preferably in a section of the curve guide that has a substantially constant width. Optionally, the curve guide can also have a further section of greater width in addition to the two end positions of the control element, for example for mounting or threading the control element.

In a preferred embodiment, at least one control device for parking and tightening the sliding sash is provided on at least two sides, in particular on the two vertical sides of the sliding sash. Not all control devices have to have a curve guidance with a maximum on all sides. Preferably, at least the control devices in the area of a center strut are provided with a curve guide with a maximum in order to cause the slide to move in opposite directions. The control devices on the other sides of the sliding sash can also be designed with a different curve guide.

In a preferred embodiment, the sliding sash is in the closed position at least one locking element held on the slide is provided, which can be locked on a locking element. The locking element can be designed as a locking plate, in particular as a rectangular locking plate, which can be inserted into a pocket-shaped receptacle of the locking element for locking. The locking element on the closing element can transmit through the control device of the sliding sash both tensile forces for pressing the sliding sash into the closed position and compressive forces for pushing the sliding sash from the closed position into the parallel parked position. A wall of the closing element thus forms a contact surface for pushing off the sliding sash. The locking element thus serves to move the sliding sash and also to lock the sliding sash in the closed position.

The closing element for the locking element is preferably fixed to a center strut in a frame, which the sliding sash moves past when moving along a running rail.

Preferably, the locking element is arranged in a pocket-shaped receptacle of the closing element with play between two walls in the direction of movement of the slide. Alternatively, the locking element can also be arranged with play between a surface of a strut, in particular a central butt strut, and a wall of the closing element. As a result, when the control element is moved along the curved guide, the locking element can initially rest against a first wall of the closing element in order to push the sliding sash from the closed position into the parallel position. When the control element passes through the maximum of the curve guidance, the slider is stopped and then moved in the opposite direction so that the locking element is lifted from the wall of the pocket-shaped receptacle and can then be easily moved out of the pocket-shaped receptacle without any grinding noises.

The wall of the closing element facing the slide preferably has a recess for the passage of at least one bolt to hold the locking element.

For an exact adjustment of the locking element relative to the slide, an adjusting device can be provided to adjust the distance between the locking element and the slide. Such an adjustment device can be carried out, for example, by a threaded bolt, eccentric or other adjustment means. For a stable fixation of the locking element two spaced bolts can be fixed to the slider in order to hold the locking element securely and stably on the slider. This also improves burglary resistance through the stable support of the locking element on the slide.

The sliding door fitting according to the invention is preferably used in a sliding door which is held movably in a frame. One or more fixed elements or further sliding doors can also be provided in the frame.

In a method for moving a control device, in particular for moving a sliding sash between a closed position and a parallel parked position, the control device comprises a curved guide formed in a slide and a control element guided in the curved guide, wherein the control element is moved relative to the curved guide and thereby the slider moves in a first direction, with further movement of the control element relative to the curve guide causing the movement of the slider to stop at a maximum of the curve guide, in order to then move the slider in a second direction when the control element is moved further relative to the curve guide to move in the opposite direction to the first direction. While the control element is continuously moved between two end positions on the cam guide in the same direction, the relative movement of the control element to the cam guide produces a reversal of movement on the slide, which is moved at least slightly in an opposite second direction. The movement of the slider in the first direction can be made significantly larger, for example at least three times larger than in the opposite second direction. As a result, the control device can, on the one hand, be used to park a sliding sash from the closed position into the parallel position, and in addition, the slide or a component connected to the slide can be removed from a contact surface during the opposite movement in order to avoid grinding noises when the sliding door is moved along the Avoid running rail.

A sliding door fitting 1 comprises two carriages for supporting a sliding sash, each carriage 2 having a roller part 3 with at least one roller 4 and a support part 5 for supporting the sliding sash. The support part 5 is displaceable relative to the roller part 3 in the axial direction of the rollers 4. The carriage 2 can be designed as shown in the EP 3 321 459 B1 is shown. To move the sliding sash, which comprises, for example, a frame with a filling element, a rotatable handle element 6 is provided, with other actuating devices or electric drives optionally also being able to be used. A gear 7 is driven via the rotatable handle element 6 in order to move drive rods 8, which are connected to one another via corner deflections 9. There are connecting rods 8 on all four sides of the sliding sash, which can be moved in the longitudinal direction via the handle element 6. Control elements 10 are fixed to the drive rods 8 and corner deflections 9 and can be moved together with the drive rods 8 and corner deflections 9. The control elements 10 are designed as pins, in particular as cylindrical or mushroom-head-shaped pins.

To move the sliding sash from the closed position into a parallel position, locking devices 11 are provided, in which a curve guide 12 is formed. By moving the controls 10 in the Using the curve guide 12, the sliding sash can be pushed out of the closed position and moved into the parallel position. The curve guide 12 includes a corresponding inclination and a widened outlet section, which is used to thread the control element 10.

Furthermore, a lower guide device 13 is provided between the two carriages 2, which cooperates with a control element 10 in order to move the sliding sash between the parallel parked position and the closed position when the drive rod 8 is moved. Another guide device 13 is provided on an upper drive rod 8. Furthermore, the sliding door fitting 1 includes upper guide elements 14, which cooperate with an upper guide rail so that the sliding sash can be moved in the parallel parked position, the upper guide rail guiding the sliding sash over the guide elements 14, which can optionally be designed as sliding or roller elements . In the lower area, the sliding sash is guided over the carriages 2.

In the exemplary embodiment shown, the sliding sash is moved to the right in the parallel position, so that a vertical center strut is arranged on the right side of the sliding door fitting 1, along which the sliding sash moves past during an opening movement. In the exemplary embodiment shown, three closing elements 15 are fixed to this center strut, the number of closing elements 15 being able to be selected depending on the size and weight of the sliding sash. Each closing element 15 includes a pocket-shaped receptacle 16 for a locking element 40, which is movable via a control device 20. The control device 20 is driven via a control element 10.

In Figure 2 one of the control devices 20 is shown in detail. The control device 20 includes a guide element 21, which is fixed to a frame of the sliding sash. For this purpose, the guide element 21 has one or more openings 22 into which screws or other fasteners are inserted. The guide element 21 has two guide strips 23, which are angular in cross section and form an edge-side groove in order to guide a slide 25 in a direction perpendicular to the longitudinal direction of the drive rod 8. The guide element 21 is fixed to the sliding sash via a plate-shaped base 24, an opening being formed in the base 24 so that the control element 10 passes through the base 24 and engages in a curved guide 26 on the slide 25. Furthermore, you can The guide element 21 can be provided with a stop to limit the range of movement of the slide 25, which prevents the slide 25 from falling out, for example during assembly.

A first sleeve 27 for fixing a bolt 30 is formed on the slide 25 in order to fix a locking element 40 on the slide 25. The bolt 30 is supported via a further sleeve 29, the first sleeve 27 and the second sleeve 29 being arranged on opposite sides of the curve guide 26. It is also possible to fix the bolt 30 to the slider 25 in another way, for example only with a sleeve or with other fastening elements.

The locking element 40 is also fixed to the slide 25 via a second bolt 33, the bolt 33 engaging in a further sleeve 28. The sleeve 27 is equipped with an internal thread in order to adjustably fix the bolt 30 to the slide 25. The sleeve 28 can optionally also have an internal thread, but in the illustrated embodiment the bolt 33 is equipped with an internal thread, so that a screw can be screwed into the bolt 33, which can be fixed to the sleeve 28 with a screw head. The sleeves 27, 28 and 29 are preferably formed integrally with the slide 25, but can also be fixed to the slide 25 via fastening means.

The locking element 40 engages in the pocket-shaped receptacle 16 of the closing element 15. One or more openings 17 are formed on the closing element 15 so that the closing element 15 can be fixed to a strut of the frame, in particular a central joint strut, via fastening means, for example screws. The distance between the locking element 40 and the slide 25 is adjustable, for which purpose a tool attachment 32 is formed on the bolt 30 in order to be able to adjust the distance via a thread. The bolt 33 is displaceably arranged in the sleeve 28 and a screw screwed into the bolt 33 can also be used to adjust the distance between the locking element 40 and the slide 25.

In the Figures 3A to 3D the control device 20 is shown in detail. It can be seen that the bolt 30 is connected to the sleeve 27 via an internal thread and the bolt 33 is guided in the sleeve 28.

The locking element 40 is essentially plate-shaped, in particular rectangular in plan view. The locking element 40 is corresponding Figure 3A arranged in the longitudinal direction of the bolts 30 and 33 with play between two walls 18 and 19. In the position shown, the locking element 40 lies against the wall 19, so that the sliding sash is held in the closed position, for example against the force of circumferential sealing strips between the frame and the sliding sash. The wall 19 includes a recess for passing the bolts 30 and 33 through to the locking element 40.

The locking element 40 is also provided at its end inserted into the pocket-shaped receptacle 16 with a tip 41, which is also spaced with play from an end wall in the pocket-shaped receptacle 16 Figure 3B and 3C is arranged. Furthermore, the locking element 40 has an extension parallel to the longitudinal direction of the drive rod 8, which is shorter than the extension of the pocket-shaped receptacle 16 in the longitudinal direction, as shown in FIG Figure 3A is shown. The play between the locking element 40 and the edges of the pocket-shaped receptacle 16 can be between 1 mm to 5 mm on both sides in the direction parallel to the longitudinal direction of the drive rod 8, preferably 2 mm to 4 mm, so that the locking element 40 has a certain tolerance within the pocket-shaped receptacle 16 can be positioned.

In Figure 3D It can be seen that the slider 25 has lateral webs which engage in the grooves on the guide strips 23.

The bolt 30 is connected to the locking element 40 via a disk-shaped head section 31 and fixed in the axial direction. A tool insert 34 is formed on the disk-shaped head section 31. A screw can be screwed into the bolt 33, which prevents the bolt 33 from being pulled out of the sleeve 28, so that both bolts 30 and 33 have a burglary-resistant effect.

In the Figures 4A and 4B the control device 20 is shown in a closed position of the sliding sash. The control element 10 is located in a section 50 of the cam guide 26, which holds the slide 25 in an end position on the guide element 21. The locking element 40, which is firmly connected to the slide 25, rests on the wall 19 of the closing element 15 and thus presses the sliding sash against sealing strips which are arranged between the frame and the sliding sash.

If the sliding sash is now to be moved from the closed position into a parallel opening position, a movement of the drive rods 8 and the corner deflections 9 is caused via the handle element 6 and the gear 7, so that the control elements 10 are also moved. As a result, the control element 10 on the control device 20 is moved along the curve guide 26 to a rising section 51, which is inclined to the longitudinal direction of the drive rod 8 and thus ensures a movement of the slide 25, which is moved to the closing element 15.

In Figures 5A and 5B the position of the control device 20 is shown when the control element 10 has reached a maximum 52 on the curve guide 26, which is formed at the end of the rising section 51. In this position, the slide 25 was moved from one end position to the opposite end position, thereby lifting the locking element 40 from the wall 19 and moving it against the wall 18 on the pocket-shaped receptacle 16, in order to then move the sliding sash over the contact with the wall 18 from the closing element 15 into the parallel position. Instead of the wall 18 on the closing element 15, the locking element 40 can also rest directly on a surface of a strut, in particular the center strut, in order to push off the sliding sash.

The ones in the Figures 5A and 5B The position of the control element 10 shown at the maximum 52 is an intermediate position, since the control element 10 is moved even further when the handle element 6 is rotated. Optionally, the handle element 6 can be locked in an intermediate position along the rising section 51, for example for a night ventilation position.

In the Figures 6A and 6B the position of the control element 10 is shown in an end position in which the handle element 6 has been rotated from a starting position to an end position. The control element 10 was moved further along the curve guide 26 over the maximum 52 into a sloping section 53. Movement from the maximum 52 in the descending section results in movement of the slider 25 out of the in Figure 5 shown end position back to a middle position in order to lift the locking element 40 from the wall 18 and to arrange it with play between the two walls 18 and 19 on the pocket-shaped receptacle 16 of the closing element 15. When moving along the curve guide 26, the slide 25 is first moved in a first direction, for example over a distance between 2 and 12 mm, in order then to move the slide 25 behind the maximum 52 in to move in an opposite second direction, for example by a distance between 0.3 mm to 2 mm. As a result, the locking element 40 is lifted off a contact surface on the wall 18, so that the sliding sash can now be moved along the running rail via the carriages 2 without the locking element 40 rubbing on the closing element 15.

In Figure 7 the curve guide 26 on the slide 25 is shown in detail. It can be seen that the curve guide 26 initially comprises a section 50 which is aligned parallel to the longitudinal direction of the drive rod 8, before a rising section 51 to a maximum 52 is provided, with the curve guide 26 passing into a descending section 53 behind the maximum 52 . The terms "rising" and "falling" are intended to describe the wave-shaped design of the curve guide 26, but do not refer to a specific spatial direction of the curve guide 26. The curve guide 26 further includes an expanded mounting section 54 for inserting the control element 10, so that the control element 10 can be designed as a mushroom head pin, which is inserted into the curve guide 26 on the widened mounting section 54. When using a cylindrical control element 10, a widened mounting section 54 can be dispensed with. Except for the mounting section 54, the curve guide 26 has essentially the same width, so that the control element 10 is guided through the walls of the curve guide 26 in these areas.
