Description

The present invention relates to a sliding door fitting, in particular for a piece of furniture, with a running rail on which at least one running track is formed, and at least one running part with at least one running roller, which can be moved along a running track of the at least one running rail, on which at least one running part a sliding door can be fixed, with at least one guide element for the at least one roller of the running part being mounted on the running rail, which forms a guide track laterally next to the track, which causes the running part to be raised and subsequently lowered when the roller is passed over, and the at least one guide element is designed as a butt connection element that connects two abutting sections of the running rail to one another, and a piece of furniture.

The EP 2 815 136 B1 discloses a mounting arrangement with two profiles lying abutting one another, which form a raceway for a roller of a sliding door fitting. In the area of the joint, a profile connector is provided, which is inserted below a raceway and supports the raceway in order to reduce downward deflection of the raceway under a weight load. This allows the track to be stabilized, although there may still be a small step between adjacent profile sections when driving over. In addition, the roller can only be moved linearly along the track.

US 6,003,201 discloses a sliding door fitting in which a sliding door can be held on a receptacle of an insert that can be inserted into a guide rail. The FR 2 708 306 shows another insert for positioning a sliding door along a travel path on a guide rail.

The DE 20 2018 106 540 discloses a sliding door fitting with the features of the preamble of claim 1.

It is therefore an object of the present invention to create a sliding door fitting that provides improved guidance for a roller of a running part.

The task is solved with a sliding door fitting with the features of claim 1.

The sliding door fitting according to the invention comprises on the running rail at least one guide element for the at least one roller of the running part, which forms a guide track laterally next to the raceway, which causes the running part to be raised and then lowered relative to the raceway when the roller is moved over, so that the at least one roller in the Area the guideway is lifted slightly from the raceway. This enables optimized guidance of the roller, which can, for example, bridge a joint area in running rails made up of several sections. In addition, deliberate braking or locking can also be carried out via the guide track, whereby the guide track is only mounted where the roller is to be influenced in order to optimize the running behavior.

Preferably, the at least one roller comprises a flange, which is arranged next to the track of the running rail and can be rolled on the guide track. As a result, the preferably circular flange can be used, on the one hand, to prevent movement of the roller in the axial direction and, on the other hand, to briefly lift the roller from the track. The track on the guide rail can be concave or convex or essentially V-shaped in order to center the roller. The lateral guidance of the roller is then effected by one or two flanges which have a larger diameter than a central section of the roller.

In an embodiment according to the invention, the at least one guide element passes through a recess in the running rail with at least one projection. As a result, the guide element can, on the one hand, be used to fix the running rail on the furniture body and, on the other hand, the guide element is also positioned in a predetermined position relative to the running rail.

The guide element preferably comprises one or more mounting openings for fixing to a furniture body using fasteners, for example screws or mounting bolts.

In a first embodiment, the at least one guide element comprises an upwardly curved guide track, which slightly raises the running part when driving over a roller and then lowers it again, for example in order to bridge a butt connection between two sections of the running rail. This achieves a gentle, harmonious rolling of the roller in the area where the track and guideway intersect, without the butt connection being unpleasantly noticeable. According to the invention, the guide element is used as a butt connector, which connects the two sections of the running rail to one another and fixes them on a furniture body. In a particularly preferred embodiment, in this first embodiment, the guide element is designed in such a way that, as a butt connector, it connects at least two sections of the running rail and at the same time causes the roller to be lifted off the track by the one or more curved guide tracks.

Preferably, the at least one guide element has at least two guide tracks for two rollers that can be moved on different tracks. Most furniture has at least two sliding doors that are guided along different tracks on a running rail, so that both tracks of a running rail can each be provided with a guide track using a guide element.

In an alternative or additional embodiment, the at least one guide element can have a locking receptacle to which the at least one roller can be locked. The locking receptacle can be formed, for example, on a resilient web, for example in the form of a locking trough. Such a locking receptacle is particularly advantageous for guiding a middle sliding door if three sliding doors can be moved on the furniture body, since the closed position of the middle sliding door can then be fixed via the guide element.

Preferably, the guide element is inserted into a groove-shaped receptacle next to a raceway. The guide element can be fixed in the groove-shaped receptacle by latching means or by clamping. For this purpose, corresponding recesses or profiles are preferably formed on the running rail, so that the guide element can be mounted on the running rail without tools.

In a further embodiment, the guide element, similar to the previous embodiment, has a guide track in a height direction, which can be designed as an upwardly curved guide track or ramp-shaped structure. This is designed with an ascending and a descending section, which are optionally connected to one another by a straight section designed as a plateau in a central area. When driving over the impact area, the flange and/or an adjacent section of a central region of the roller rolls on the guide track of the guide element, so that the roller is lifted from the track of the running rail. In addition, the guide element has laterally arranged wall sections, wherein in a depth extension an inside of at least one wall section can be designed as a ramp-shaped structure or as a curved surface. Preferably, this ramp-shaped structure or the curved surface is achieved in that the wall section is designed with a constantly increasing thickness, with the respective end sides having a smaller thickness and a central section having a larger one Thickness. The middle area can have a plateau with a uniform thickness. The ramp-shaped structure or the curved surface acts as a second, laterally formed guide track for the roller in a depth direction. Particularly preferably, both wall sections of the guide element are provided with such a ramp-shaped structure or curved surface, so that the clear width of the cavity of the guide element steadily decreases starting from the respective end sides towards the middle section. This second guide track, designed as a ramp-shaped structure or curved surface, causes the roller to move axially in the direction of the furniture body and thus enables a moving but constant contact point between the roller and the track when the guide element is moved over. Thus, when the guideway passes over the abutting area of the sections of the running rail, the roller is raised in the height direction from the track of the running rail in a height direction, but due to the lateral design of the second guideway as a result of its axial movement in the direction of the furniture body, it maintains its constant contact a guide on the track, with the contact point moving to the guide element depending on the position of the roller. This advantageously ensures that the roller is lifted from the track in the height direction when passing over the joint area due to the guide track, but at the same time continues to be guided on the track with a section due to the second guide track, in that a moving contact area is formed on an opposite section of the track Roller rolls on the track. This effectively prevents the roller and thus the sliding door from tilting towards a vertical direction.

Preferably, the running rail has at least two separate sections which are supported in the joint area by a support device against lowering. The support device can either be designed integrally with the guide element or as a separate component. Assembly as a separate component has the advantage that the guide element and the support device can be made from different materials, with the support device being made from a material with higher strength, for example metal. The support device can be essentially angular and fixed to an underside of a top shelf of a piece of furniture in order to support the running rail.

Preferably, the support device comprises at least one displaceable or pivotable web or projection, which is in the abutment area of the running rail is movable from a retracted position to a projected position to support a raceway on the track. This simplifies assembly, since the pivotable or displaceable web or projection is only moved through an opening in the running rail after assembly of the support device in order to provide support at the desired position in the joint area.

The invention is preferably used in furniture, with at least one sliding door being movably held on a furniture body with a corresponding sliding door fitting. In addition, the sliding door fitting can also be used on sliding doors for room dividers or for other purposes.

A piece of furniture 1 includes a furniture body 2, on which an opening can be closed by one or more sliding doors 5 or 6. On the furniture body 2, a running rail 3 is fixed to an upper floor, on which one or more running parts 4 are movably mounted, on each of which a sliding door 5 or 6 is held. In the exemplary embodiment shown, a front sliding door 5 and a rear sliding door 6 are provided, the front sliding door 5 being held on two running parts 4. In a lower area of the sliding doors 5 and 6, guide means can also be provided in order to guide or move the sliding doors 5 and 6 along the furniture body 2.

As in Figure 1B is shown, the running rail 3 is formed from two adjacent sections 3a and 3b, which are arranged abutting one another. In the area of the adjacent ends of the two sections 3a and 3b, a guide element 10 is provided, which serves to guide the roller 7 of a running part 4. In the exemplary embodiment shown, two raceways 8 and 9 are provided on the running rail 3, which are arranged one above the other and which are contacted by the roller 7 when driving over them.

In Figure 2 is the sliding door fitting Figure 1 shown in a side view. An upper roller 7 is rotatably mounted on a running part 4 on which the front sliding door 5 is held. The roller 7 of the running part 4 is guided on the upper raceway 9, the raceway 9 being curved upwards in a convex configuration. In addition to the track 9, a flange 72 is provided at the end in the axial extension of the track roller 7, which has a slightly larger diameter than the central area of the track roller 7 and thus provides lateral guidance when the track roller 7 rests on the track 9 ensures.

On the running part 4 there is also a lifting protection 11 in the form of a lever which, in the securing position, engages under the raceway 9 with a hook-shaped section 12 and thus only allows the sliding door 5 to be lifted until the hook-shaped section 12 hits the underside of the raceway 9 . This distance is so short that the flange 72 cannot be pulled off over the raceway 9 in the axial direction of the roller 7.

On the lower raceway 8 there is also a roller 7 of a further running part 40 for the rear sliding door 6, the guidance of the roller 7 being the same for the two running parts 4 and 40, so that only the upper running part 4 is described in detail.

In the Figures 3A and 3B the roller 7 is arranged on the track 9. A middle section 70 of the roller 7 is in contact with the top of the raceway 9 in the lower region, so that the weight forces of the front sliding door 5 are thus transferred to the raceway 9 via the middle section 70. In the middle section 70, a centrally arranged groove or groove 71 is provided, which serves for centering and can optionally be omitted can. To the side of the upwardly curved raceway 9, two flanges 72 are provided, which border the raceway 9 on opposite sides.

If the running part 4 is now moved towards the guide element 10 when the roller 7 is moved on the track 9, the flange 72 comes into engagement with a guide track 13 arranged on the guide element 10, as shown in Figure 4A is shown. Due to the upwardly curved guide track 13, the roller 7 is lifted from the track 9, so that a small gap is created between the top of the track 9 and the middle section 70 of the track roller 7. The hook-shaped section 12 of the anti-lift device 11 is now also slightly raised and arranged just below the underside of the raceway 9. The raceways 8 and 9 formed on the rail 3 are arranged in different horizontal planes, which are arranged offset from one another in a vertical direction, the raceways 8 and 9 being arranged vertically to one another in an axial direction of the rollers 7.

In the Figures 5A and 5B the guide element 10 is shown in detail. The guide element 10 can preferably be made in one piece from plastic and comprises an angular section with an upper side 15 on which one or more mounting openings 16 are provided so that fasteners can fix the guide element 10 to the underside of a top floor. Furthermore, further mounting openings 18 are provided on a front side 17 angled from the top 15, into which fastening means can be inserted in order to connect the sections 3a and 3b of the running rail 3 to one another in abutting manner. On the front 17, two web-shaped guide tracks 13 and 14 protrude upwards, which are curved upwards and on which the flange 72 of the roller 7 can roll. On the sides of the guide tracks 13 and 14, in an extension parallel to the running rail 3, webs 19 are formed, which ensure secure guidance of the flange 72 as long as the flange 72 rolls on the guide track 13 and / or 14.

In the Figures 6A and 6B the running rail 3 is shown without the guide element 10. The two sections 3a and 3b have in their joint area a lower recess 30 and an upper recess 31, which is arranged adjacent to the raceway 8 and 9, respectively. Furthermore, 3 mounting openings 32 are provided on the running rail, which are aligned with the mounting openings 18 of the guide element 10 in the mounting position.

Like those too Figures 7A and 7B show, the web-shaped guide track 13 of the guide element 10 passes through the upper recess 31 and the web-shaped guide track 14 passes through the lower recess 30, so that the guide tracks 13 and 14 are arranged parallel next to the raceways 8 and 9 in the mounted position. If a roller 7 passes over the joint area between the two sections 3a and 3b of the running rail 3, the raceway 8 or 9 can end up lowering slightly due to the weight load. In order to avoid a step-like approach to the adjacent section 3a or 3b or to ensure a gentle, harmonious rolling of the roller 7 on the running rail 3, the roller 7 is lifted slightly in the relevant joint area by the upwardly curved guide track 13 formed on the guide element 10 or 14, so that the user can hardly notice that two sections 3a and 3b were assembled via a butt joint. This allows the transport volume of a piece of furniture to be reduced because the running rail 3 is the largest component when made in one piece.

In the Figures 8A to 8C an embodiment of a sliding door fitting not according to the invention is shown, which has a modified guide element 20. In this case, the guide element 20 is not mounted in a joint area between adjacent sections 3a and 3b of a running rail 3, but can optionally also be mounted in such a joint area. The guide element 20 comprises a guide track 23, which is not designed to be curved upwards, but rather has two spaced-apart curvatures, between which a central locking receptacle 24 designed as a locking trough is formed. As a result, the roller 7 can be lifted slightly when driving over one of the two curvatures of the guide element 20 via the contact of the flange 72 with the guide track 23 and locked on the locking receptacle 24. This is particularly advantageous for medium-sized sliding doors if the closing position is to be fixed by a lock.

In Figure 9 the guide element 20 is shown in detail. The guide element 20 includes two pins 21 and 22 for fasteners to pass through, which facilitate fixing the guide element 20 to a furniture body. The pins 21 and 22 are connected to one another on a web 25, from which the guide track 23 protrudes. For this purpose, the guide track 23 is held on two sections 26 which are angled at the ends and which are formed integrally with the web 25. Between the two angled ones Sections 26 extend the corrugated guide track 23 with the central locking receptacle 24.

In Figure 10 the sliding door fitting is shown without the guide element 20. It can be seen that a recess 31 is provided on the upper raceway 9, through which the guide track 23 can be carried out. Furthermore, two mounting openings 32 are provided, which are aligned with the openings on the pins 21 and 22 in the mounted position.

In the exemplary embodiment of Figures 8 to 10 only a guide element 20 is shown on the upper raceway 9. It is of course also possible to provide a further guide element on the lower raceway 8.

In addition, the two embodiments can also be combined with one another in a piece of furniture 1, especially if three sliding doors 5 and 6 are provided and the middle sliding door is to be locked in a closed position.

In the exemplary embodiment shown, the running rail 3 has raceways 8 and 9, which are arranged vertically offset. It is also possible to modify the running rail with regard to the number of tracks and their arrangement, which can also be done side by side.

Figure 11 shows a further exemplary embodiment of a sliding door fitting with a running rail 3, which is formed from two sections 3a and 3b, with a guide element 50 adjacent to the raceway 8 and a further guide element 50 adjacent to the raceway 9 in the joint area, each in a groove-shaped receptacle of the running rail 3 are arranged. As in the previous exemplary embodiments, the running rail 3 is fixed to a top panel of a furniture body 2.

In the Figures 12A to 12C a guide element 50 is shown in detail. The guide element 50 is strip-shaped and has a length, for example, between 40 mm and 400 mm, in particular 80 mm to 300 mm. The guide element 50 is essentially U-shaped in cross section and comprises a first wall section 52, a base 51 and a second wall section 53, each of which extends in the longitudinal direction of the guide element 50. On the outside of the wall section 53, a plurality of fastening projections 54 are formed, which are located in an opening or receptacle can be fixed on the running rail 3 by clamping or latching. On the bottom 51, one or more projections 55 are also provided on the underside, which can be inserted into an opening or receptacle in the running rail 3, so that the guide element 50 is secured against displacement in the longitudinal direction.

How Figure 12B shows in a schematic view, the floor 51 consists of a rising section with respect to a horizontal plane, starting from an end side in the longitudinal direction of the guide element 50, of a plateau with a uniform path in a central region of the guide element 50 and a descending section up to the opposite one End side in a longitudinal extent of the guide element 50. Due to this shape, the bottom 51 acts functionally like the guide track 13, 14 in the first exemplary embodiment.

In addition, the wall sections 52 and 53 of the guide element 50 have a similar shape on their respective insides to the guide track 51, only arranged at an angle to it. The top view in Figure 12B shows schematically that the two end sides of the wall sections 52 and 53 are provided with a small thickness and increases steadily towards the central region of the guide element 50. A plateau with a uniform path is formed in the middle area. A ramp-like structure is thus formed which acts as a second, laterally arranged guide track 57. By forming the guide tracks 57 on the wall section 52 and the wall element 53, the clear width of the cavity of the guide element 50 changes in such a way that the cavity is narrowed in the direction of the central region 56. The guide track 57 can be designed on both wall sections 52 and 53; alternatively, training for just one wall section 52 is also conceivable.

In the Figures 13A and 13B Two rollers 7 are shown from the two running parts 4 and 40, not shown, which are arranged at a distance from the joint area of the two sections 3a and 3b of the running rail 3. As in the previous exemplary embodiments, the rollers 7 rest on the raceways 8 or 9 with a central section 70.

In the joint area of the two sections 3a and 3b, the flange 72 comes into engagement with the guide track 51 arranged on the guide element 50 when the roller 7 is moved on the raceways 8, 9, which is as previously described is designed as a ramp-shaped structure of a floor. As a result, the roller 7 is gently raised on the rising section of the guide track 51 until the plateau is reached, and then lowered again on the descending section of the floor 51.

In the Figures 14A and 14B the rollers 7 are shown in the area of the joint between the two sections 3a and 3b of the running rail 3. It can be seen that the middle section 70 of the rollers 7 no longer rests directly on the raceways 8 or 9, but that a flange 72 rests on the guide element 50. In addition and almost simultaneously with the performance of the function of the guide track 51, the guide track 57 acts, in that its shape follows the shape of the guide track 51, and is only twisted at an angle to it, preferably by 90 °. The inside of the flange 72 causes the roller 7 to move axially in the direction of the furniture body 2 by striking the guide track 57. As a result, the roller 7 maintains constant contact with the raceway 8, 9 when passing over the joint, the contact point being due to the axial Moving the roller 7 moves to the guide element 50 depending on its position. As a result, the roller 7 rolls on the guide track 51 of the guide element 50 when passing over the joint, but at the same time is guided by the guide track 57 on the track 8, 9. A possible tilting of the roller 7 and thus the sliding door 5,6 towards a vertical direction is thereby effectively avoided. The horizontal and axial movement of the roller 7 and the sliding door 8, 9 while driving over the joint is so minimal that it is hardly noticed by the user.

A support device 60 is also mounted on the running rail 3, which is essentially angular in shape, with one leg being fixed to an underside of the top floor. Both a web of the running rail 3 lying on the top floor and the support device 60 can be fixed using a fastening means.

In the Figures 15A and 15B the support device 60 is shown in detail. The support device 60 comprises a horizontal leg 61, which is fixed to the underside of the top floor using fasteners, for example screws. A vertical leg 62 of the support device 60 rests on a back side of the running rail 3 and thus prevents a bending movement in the joint area between the two sections 3a and 3b. Furthermore, a bend 63 is formed on the leg 62, which serves to support the lower Career 8 serves. One or more upwardly projecting projections 64 can be formed on the bend 63, which support a section adjacent to a raceway 8 or pass through an opening in the running rail 3. The upper raceway 9 is supported by a web 67, which is between a retracted assembly position ( Figure 15 ) and a protruding support position ( Figure 16 ) is movable. The web 67 is integrally formed with a slide 65, which has an elongated hole and is guided on the leg 61 via a bolt 66. The web 67 passes through an opening in the leg 62 and can thus be moved into a protruding position after mounting the support device 60 on the furniture body 2 in order to support an area adjacent to the track 9, as also shown in Figure 14B is shown. It can be seen that the web 67 engages under the running rail 3 in the area of the groove-shaped receptacle into which the guide element 50 is inserted adjacent to the upper raceway 9. The guide element 50 next to the lower raceway 8 is also inserted into a groove-shaped receptacle and is supported by the bend 63.

In the Figures 17A to 17D the assembly of the support device is shown. 17A, the running rail 3 with the two sections 3a and 3b is pre-assembled on the top floor of the furniture body 2, and in the next step the support device 60 is fixed with the leg 61 on the underside of the top floor, as shown in Figure 17B is shown.

For further assembly, a first guide element 50 is then inserted into the groove-shaped receptacle next to the raceway 9 and a second guide element 50 is inserted into the groove-shaped receptacle next to the raceway 8. Furthermore, the slider 65 is guided from the retracted mounting position by the leg 62, so that the web 67 supports the guide element 50 on the running rail next to the track 9. In Figure 17D The installed position of the sliding door fitting is then shown.
