Description

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

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 parked position, so that the carriage can then be moved along a running rail. Such a sliding door fitting has proven itself, but control devices must be provided on several sides of the sliding sash for putting down or tightening the sliding sash. In the area of a central joint strut, which the sliding sash passes 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 parking the sliding sash can be integrated into the carriage, as shown in FIG DE 10 2014 220 837 B3 is revealed. The provision of a curved guide on the carriage weakens the support structure and goes against the requirement for a compact design. In addition, further control devices and locking arrangements must be positioned very precisely.

the EP 2 682 545 B1 discloses a locking arrangement for a sliding door, in which a mushroom head is fixed on a transverse slide and engages in a receptacle of a locking element for locking. With an exact alignment of the closure element and the mushroom head, a locking can take place via such a closure element, but no forces for pushing the sliding sash are transmitted in order to move it from the closed position into the parallel parked position. As a result, corresponding control devices for parking 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 mounted separately.

It is therefore the object of the present invention to provide a sliding door fitting for a sliding sash and a method for moving a control device which is easy to assemble and by means of which a sliding sash 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 13.

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 cam guide formed in a slide and a control element guided in the cam guide, the control element being moved 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 over the control device from the closed position into the parallel parked position, the section of the cam guide after the maximum being used to move the slide in the opposite direction to move the slide from the Lift off the contact surface for pressing the sliding sash. This movement thus ensures that the slide or a component connected to the slide is spaced apart 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 parked position back in 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 To arrange prints. This measure also allows control devices to be arranged in the area of a central joint strut, so that the sliding sash is better guided when it is put down or pulled on. A central strut is arranged in a frame, which the sliding sash drives past when it is opened. A center strut can be a vertical strut between a lower strut and an upper strut of a window frame, but also a strut of a frame of a fixed field or of another sliding sash.

The curve guide preferably 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 guide between the closed position and the parallel parked position. The curve guide can of course be arranged anywhere in the room, 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 that forms a wave. The first section in the upward direction is preferably longer than the second section in the downward direction; in particular, the sliding sash on the upward portion can be pushed off 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 pressing the sliding sash. The control element can preferably be moved via a rotatable grip element which can be moved between two end positions.

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

In a preferred embodiment, at least one control device is provided on at least two sides, in particular on the two vertical sides of the sliding sash, for putting down and tightening the sliding sash. Not all control devices have to have a curve guide with a maximum on all sides. Preferably, at least the control devices in the area of a central strut are provided with a curved guide with a maximum in order to bring about a counter-rotating movement of the slide. The control devices on the other sides of the sliding sash can also be designed with a different curve guide.

In a preferred embodiment, at least one locking element held on the slide is provided in the closed position of the sliding sash, 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 closing element for locking. The locking element on the closing element can transmit both tensile forces for pressing the sliding sash into the closed position and compressive forces for pushing the sliding sash out of the closed position into the parallel parked position through the control device of the sliding sash. A wall of the closing element thus forms a contact surface for pressing the sliding sash off. Thus, the locking element is used 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.

The locking element is preferably arranged in the direction of movement of the slide with play between two walls in a pocket-shaped receptacle of the closing element. Alternatively, the locking element can also be arranged with play between a surface of a strut, in particular a central joint strut, and a wall of the closing element. As a result, when the control element is moved along the curve 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 parked position. When the control element passes through the maximum of the curve guide, the slide 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 moved easily 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 for holding the locking element.

For an exact adjustment of the locking element relative to the slide, an adjusting device can be provided in order to adjust the distance between the locking element and the slide. Such an adjusting device can be implemented, for example, by means of a threaded bolt, eccentric or other adjusting means. For a stable fixation of the locking element you can two spaced bolts can be fixed on the slide in order to hold the locking element in a rotationally secure and stable manner on the slide. This also improves the burglary prevention 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 that is movably held 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, the control element being moved relative to the curved guide and thereby moves the slider in a first direction, further movement of the control element relative to the cam guide causes the movement of the slider to stop at a maximum of the cam guide, in order to then close the slider in a second direction when the control element is moved further relative to the cam 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 movement of the control element relative to the cam guide generates a movement reversal on the slide, which is moved at least slightly in an opposite second direction. The movement of the slide 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 be used on the one hand to move a sliding sash from the closed position into the parallel position, and the slide or a component connected to the slide can be removed from a contact surface when moving in opposite directions in order to avoid grinding noises when moving the sliding door along the Avoid running track.

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 FIG EP 3 321 459 B1 is shown. To move the sliding sash, which comprises a frame with a filling element, for example, a rotatable handle element 6 is provided, with other actuation devices or electrical drives optionally also being able to be used. A gear 7 is driven via the rotatable grip element 6 in order to move drive rods 8 which are connected to one another via corner deflections 9. Driving rods 8 are provided on all four sides of the sliding sash and can each be moved in the longitudinal direction via the handle element 6. Control elements 10, which can be moved together with the drive rods 8 and corner deflections 9, are fixed to the drive rods 8 and corner drives 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 parked position, closing devices 11 are provided in which a curved guide 12 is formed. By moving the controls 10 in the Curved guide 12, the sliding sash can be pushed out of the closed position and moved into the parallel parked position. The curved guide 12 comprises 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 interacts 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 comprises upper guide elements 14 which interact 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 carriage 2.

In the illustrated embodiment, the sliding sash is shifted to the right in the parallel parked position, so that a vertical center strut is arranged on the right-hand side of the sliding door fitting 1, along which the sliding sash moves during an opening movement. In the exemplary embodiment shown, three closing elements 15 are fixed to this center strut, and the number of closing elements 15 can be selected as a function of the size and weight of the sliding sash. Each closing element 15 comprises a pocket-shaped receptacle 16 for a locking element 40, which can be moved 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 comprises 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 fastening means are inserted. The guide element 21 has two guide strips 23 which are angular in cross section and form a groove on the edge 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 reaches through the base 24 and engages in a curved guide 26 on the slide 25. Furthermore, at the guide element 21 can be provided with a stop to limit the range of motion 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 by a further sleeve 29, the first sleeve 27 and the second sleeve 29 being arranged on opposite sides of the curved guide 26. It is also possible to fix the bolt 30 in another way on the slide 25, 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 fix the bolt 30 on the slide 25 in an adjustable manner. The sleeve 28 can optionally also have an internal thread, but in the embodiment shown 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 window 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, a tool attachment 32 being formed for this purpose on the bolt 30 in order to be able to adjust the distance via a thread. The bolt 33 is arranged displaceably 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 rests 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 comprises a recess for the bolts 30 and 33 to pass 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 according to FIG 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 in the direction parallel to the longitudinal direction of the drive rod 8 on both sides between 1 mm to 5 mm, preferably 2 mm to 4 mm, so that the locking element 40 with a certain tolerance within the pocket-shaped receptacle 16 can be positioned.

In Figure 3D it can be seen that the slide 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 is 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 break-in-inhibiting 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 curved guide 26, which holds the slide 25 in an end position on the guide element 21. The locking element 40 firmly connected to the slide 25 rests against 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 parked open position, a movement of the drive rods 8 and the corner deflectors 9 is effected 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 curved 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 towards 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, whereby the locking element 40 was lifted from the wall 19 and moved against the wall 18 on the pocket-shaped receptacle 16, then around the sliding sash via contact with the wall 18 to be pressed from the closing element 15 in the parallel parked 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 central joint strut, in order to push off the sliding sash.

The ones in the Figures 5A and 5B The position shown of the control element 10 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 grip element 6 can be latched in an intermediate position along the rising section 51, for example for a gap ventilation position.

In the Figures 6A and 6B the position of the control element 10 is shown in an end position in which the grip element 6 has been rotated from an initial 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. The movement from the maximum 52 in the sloping section leads to a movement of the slide 25 from the position shown in FIG Figure 5 end position shown back into 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. The slide 25 is thus initially moved in a first direction when moving along the curved guide 26, for example over a distance between 2 and 12 mm, in order to then move the slide 25 behind the maximum 52 in to move 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 from 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 dragging against the closing element 15.

In Figure 7 the cam guide 26 on the slide 25 is shown in detail. It can be seen that the curved 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 is provided to a maximum 52, the curved guide 26 merging into a sloping section 53 after the maximum 52 . The terms "rising" and "falling" are intended to describe the wave-shaped design of the curved guide 26, but do not relate to a specific spatial direction of the curved guide 26. The curved guide 26 further comprises an expanded mounting section 54 for inserting the control element 10, so that the control element 10 can be designed as a mushroom pin which is inserted into the curved guide 26 at the widened mounting section 54. When using a cylindrical control element 10, a widened mounting section 54 can be dispensed with. With the exception of the mounting section 54, the curved guide 26 has essentially the same width, so that the control element 10 is guided through the walls of the curved guide 26 in these areas.
