Description

The present invention relates to a locking device, in particular for a sliding door fitting, with a control element that can be moved by a drive rod, a slide that is movably guided on a guide element and has a curved guide in which the control element can be moved, and one connected to the slide via a first bolt Locking element which can be locked on a closing element.

the EP 2 682 545 B1 discloses a locking arrangement for a sliding door, in which a mushroom head is fixed to a transverse slide and can be locked to a receptacle of a locking element. The mushroom head must be inserted relatively precisely into the receptacle of the closure element, which makes an exact alignment of the closure element and the mushroom head necessary during assembly. Furthermore, the forces for securing a sliding sash in the locked position are limited by such a mushroom head, which leads to a low level of burglary resistance.

It is therefore the object of the present invention to create a locking device that is easy to assemble and can absorb higher forces to prevent burglary.

This object is achieved with a locking device with the features of claim 1.

In the locking device according to the invention, a slide is connected to a locking element via a first bolt and via at least one further second bolt, so that the slide and locking element are arranged securely and stably relative to one another via the at least two bolts. In order to overcome the holding forces of the locking element which can be locked on a closing element, the holding forces of the two bolts must therefore be overcome before the sash can be broken out of its locked position. This increases the protection against break-ins, since considerable forces have to be expended to overcome the holding forces of the two bolts.

At least one sleeve for fixing the respective bolt is preferably provided on the slide for each bolt. This creates a stable connection between the bolt and slide, which can be easily assembled by inserting or screwing the bolt into the respective sleeve.

For simple assembly, the locking element can be inserted in the longitudinal direction of the drive rod with play in a pocket-shaped receptacle of the closing element. The play in the longitudinal direction of the drive rod can be, for example, in a range between 2 mm to 20 mm, in particular 4 mm to 12 mm, so that the alignment of the locking element and the locking element has to be less precise during assembly and certain tolerances are allowed without impairment of function .

The locking element is preferably designed as a locking plate. The plate can be designed essentially rectangular in plan view. A front edge, which lies at the front in the direction of insertion into the closing element, preferably tapers to a point, so that threading the locking element into the closing element is facilitated.

In a preferred embodiment, the locking element is arranged in the direction of movement of the slide with play between two walls in the pocket-shaped receptacle of the closing element. As a result, the locking element can be used both for pushing off and for tightening a sliding sash. When the drive rod is moved in a first direction, the locking element can rest against a first wall of the pocket-shaped receptacle and push a wing out of the closed position into a position that is parked in parallel. If the drive rod is moved in a second direction opposite to the first direction, the locking element can rest against the opposite second wall of the closing element and attract the wing from the parallel parked position into a closed position. The locking element thus not only serves to lock the sash in the closed position, but can also be used actively as a control device for pulling in and pushing off the sash.

The locking device according to the invention is preferably used in a sliding door fitting, in particular for parallel parking of a sliding sash, which can then be moved in the parallel parking position via one or more carriages along a running rail. In such a sliding door, the sliding sash can be arranged in a frame, the closing element preferably on a center strut in the The frame is fixed, which is aligned vertically and which the sliding sash moves past when moving along the 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 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, which over the handle element 6 are each movable in the longitudinal direction. 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 control elements 10 in the curve 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 attached to a frame of the Sliding sash is fixed. 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, a stop can be provided on the guide element 21 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 on the slide 25 in some other 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 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 45 is 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, with a tool attachment 32 being formed on the bolt 30 for this purpose in order to adjust the distance via a thread to be able to adjust. The bolt 33 also comprises a thread and a tool insert for adjusting the distance.

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 45 is 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 further along the curve guide 26 over the maximum 52 into a sloping section 53 procieedings. 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 curve guide 26, for example over a distance between 2 and 12 mm, in order then to move the slide 25 behind the maximum 52 in a second opposite 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.
