Description

Sliding door fittings and furniture

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, with at least one running part a sliding door can be fixed, and a piece of furniture.

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

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

The object is achieved with a sliding door fitting with the features of claim 1.

The sliding door fitting according to the invention comprises at least one guide element for the at least one roller of the running part on the running rail, which forms a guide path on the side next to the running track, which causes the running part to be raised and then lowered relative to the running track when the running roller is driven over, so that the at least one The roller in the area of the guideway is raised slightly from the track. This enables the optimized guidance of the roller, which can bridge a joint area, for example, in the case of tracks formed from several sections. In addition, deliberate braking or locking can be carried out via the guideway, the guideway being only installed where the caster should be influenced in order to optimize running behavior. The at least one roller preferably comprises a flanged wheel which is arranged next to the track of the track and can be rolled on the guide track. As a result, the preferably circular flanged wheel can be used on the one hand to prevent the roller from moving in the axial direction and on the other hand to lift the roller briefly from the track. The track on the guide rail can be concave or convex or essentially V-shaped to center the roller. The lateral guidance of the roller is then effected by one or two flanged wheels which have a larger diameter than a central portion of the roller.

In a further embodiment, 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 be used on the one hand to fix the running rail to 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 by means of fastening means, for example by screws or mounting bolts.

In a first embodiment, the at least one guide element comprises an upwardly curved guide track, which slightly raises and then lowers the running part again when driving over a roller, for example in order to bridge a butt connection between two sections of the running rail. This ensures smooth, harmonious rolling of the roller in the area where the track and guideway intersect, without the butt joint being perceived as unpleasant. Then the Füh approximately element can also be used as a butt connector that connects the two sections of the track together and fi xed to a furniture body. In a particularly preferred embodiment, the guide element in this first embodiment is designed such that it connects at least two sections of the running rail as a butt connector and at the same time causes the roller to be lifted from the running track by the one or more curved guideway. The at least one guide element preferably has at least two guide tracks for two running rollers which can be moved on different tracks. Most of the furniture has at least two sliding doors, which are guided along different tracks on one track, so that both tracks of a track can be provided with one track each with one guide element.

In an alternative or additional embodiment, the at least one guide element can have a latching receptacle on which the at least one roller can be latched. The latching receptacle can be formed, for example, on a resilient web, for example in the form of a latching depression. Such a locking receptacle is particularly advantageous for guiding a middle sliding door when three sliding doors can be moved on the furniture body, since then the closed position of the middle sliding door can 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 locking means or by clamping. For this purpose, corresponding recesses or profilings 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, similar to the previous embodiment, the guide element has a guide track in a height direction, which can be designed as an upwardly curved guide track or a ramp-shaped structure. This is designed with a rising and a falling section, which are optionally connected to one another in a central region by a straight section designed as a plateau. When driving over the impact area, the flanged wheel and / or an adjacent section of a central area of the roller rolls on the guideway of the guide element, so that the roller is lifted from the track of the track ne. In addition, the guide element has laterally arranged wall sections, it being possible for an inside of at least one wall section to be designed as a ramp-shaped structure or as a curved surface in a depth extension. This ramp-shaped structure or the curved surface is preferably achieved in that the wall section is designed with a constantly increasing thickness, the respective end sides having a smaller thickness and a central section having a larger greater thickness. The middle region can have a plateau with a uniform thickness. The ramp-shaped structure or the curved surface acts as a second, laterally formed guideway for the roller in a depth direction. Both wall sections of the guide element are particularly preferably provided with such a ramp-shaped structure or curved upper surface, so that the clear width of the cavity of the guide element, starting from the respective end sides, gradually decreases towards the middle section. This second as a ramp-shaped structure or curved surface guideway causes an axial movement of the roller in the direction of the furniture body and thus allows a moving but steady contact point between the roller and the track when driving over the guide element. Thus, the roller is run over in the joint region of the sections of the track by the guide track in the height direction from the track of the track rail in a height direction, but due to the lateral formation of the second guide track due to its axial movement in the direction of the furniture body by the constant contact with a guide on the track, the contact point moving depending on the position of the roller to the guide element. In an advantageous manner, it is thus achieved that the roller is lifted from the track in the height direction when passing over the impact area as a result of the guideway, but at the same time continues to be guided along the track with a section as a result of the second guideway, by a moving contact area on an opposite section the roller rolls on the track. This effectively prevents the roller and thus the sliding door from tilting to a vertical direction.

The running rail preferably has at least two separate sections, which are supported in the joint area by a supporting device against lowering. The support device can optionally be integrally formed with the guide element or as a separate component. The assembly as a separate component has the advantage that the guide element and the Stützvor direction can be made of different materials, the support device being made of a material with higher strength, for example metal. The support device can be formed substantially angularly and fixed to an underside of an upper floor of a piece of furniture in order to support the running rail.

The support device preferably comprises at least one displaceable or pivotable web or projection, which rail is movable from a retracted position to a projecting position to support a track 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, wherein at least one sliding door with a corresponding sliding door fitting is kept movable on a furniture body. In addition, the sliding door fitting can also be used for sliding doors for room dividers or for other purposes.

The invention is explained in more detail below using several exemplary embodiments with reference to the accompanying drawings. Show it:

Furniture 1 comprises a furniture body 2 on which an opening can be closed by one or more sliding doors 5 or 6. A running rail 3 is fixed to the furniture body 2 on 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 illustrated embodiment, a front sliding door 5 and a rear sliding door 6 is provided, the front sliding door 5 being held on two running parts 4. In a lower area of the sliding door Ren 5 and 6 can also be provided guide means to guide and slide the sliding doors 5 and 6 along the furniture body 2.

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

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

A lifting device 11 in the form of a lever is also provided on the running part 4, which engages under the track 9 in the securing position with a hook-shaped section 12 and thus only allows the sliding door 5 to be lifted until the hook-shaped section 12 on the underside of the track 9 on strikes. This distance is so small that the flanged wheel 72 cannot be pulled off the track 9 in the axial direction of the roller 7.

On the lower track 8, a roller 7 of a further barrel part 40 is also provided for the rear sliding door 6, the guidance of the roller 7 in the two barrel parts 4 and 40 being the same, so that only the upper barrel part

4 is described in detail.

In FIGS. 3A and 3B, the roller 7 is arranged on the track 9. A middle section 70 of the roller 7 is in the lower region in contact with the top of the track 9, so that the weight of the front sliding door

5 are thus removed over the middle section 70 onto the raceway 9. In the middle section 70, a centrally arranged groove or groove 71 is seen before, which is used for centering and optionally also be omitted can. Laterally next to the upwardly curved track 9, two flanges 72 are provided, which surround the track 9 on opposite sides.

If the running part 4 is now moved towards the guide element 10 during the movement of the roller 7 on the track 9, the flanged wheel 72 comes into engagement with a guide track 13 arranged on the guide element 10, as shown in FIG. 4A. The track 7 is raised from the track 9 by the upwardly curved guide track 13, so that a small gap is formed between the top of the track 9 and the central section 70 of the track 7. The hook-shaped section 12 of the anti-lifting 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 here in different horizontal planes which are 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.

The guide element 10 is shown in detail in FIGS. 5A and 5B.

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 fastening means can fix the guide element 10 on the underside of an upper floor. Furthermore, on an angled from the top 15 front side 17 further mounting openings 18 are provided, in which Befestigungsmit tel can be inserted in order to connect the sections 3a and 3b of the running rail 3 with one another in a butt joint. On the front side 17 two web-shaped guideways 13 and 14 protrude upwards, which are arched upwards and on which the flanged wheel 72 of the roller 7 can roll. On the sides of the guideways 13 and 14, in an extension pa parallel to the running rail 3, webs 19 are formed in each case, which ensure reliable guidance of the flanged wheel 72 as long as the flanged wheel 72 rolls on the guideway 13 and / or 14.

FIGS. 6A and 6B show the running rail 3 without the guide element 10. The two sections 3a and 3b have in their butt region egg ne lower recess 30 and an upper recess 31 which is arranged adjacent to the raceway 8 and 9 respectively. Furthermore, 3 Mon opening 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. As also shown in FIGS. 7A and 7B, the web-shaped guideway 13 of the guide element 10 passes through the upper recess 31 and the web-shaped guideway 14 extends through the lower recess 30, so that the guideways 13 and 14 in the mounted position parallel to the raceways 8 and 9 are arranged. If a roller 7 passes over the joint area between the two sections 3a and 3b of the running rail 3, the track 8 or 9 can lower somewhat at the end due to the weight load. In order to avoid a step-like approach to the adjacent section 3a or 3b or to ensure a smooth, harmonious rolling of the roller 7 on the running rail 3, the roller 7 is raised slightly in the impact region in question by the guide element 10 formed on the upwardly curved guide track 13 or 14, so that it is hardly noticeable to the user that two sections 3a and 3b were assembled via a butt joint. As a result, the transport volume of a piece of furniture can be reduced because the running rail 3 is the largest component in the one-piece design.

FIGS. 8A to 8C show a further exemplary embodiment of a sliding door fitting 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 on such a joint area. The guide element 20 comprises a guide track 23, which is not arched upwards, but has two spaced-apart arches, between which a central locking receptacle 24 designed as a locking trough is formed. As a result, the roller 7 can be slightly raised when passing over one of the two curvatures of the guide element 20 via the contact of the flanged wheel 72 with the guide track 23 and can be latched to the latching receptacle 24. This is particularly advantageous for medium-sized sliding doors, if the closed position is to be fixed by a latch.

In Figure 9, the guide element 20 is shown in detail. The guide element 20 comprises two pins 21 and 22 for a penetration of fastening means which facilitate fixing the guide element 20 to a furniture body. The pins 21 and 22 are connected to each other on a web 25 from which the guideway 23 protrudes. For this purpose, the Füh approximately 23 is held at two end angled sections 26 which are integrally formed with the web 25. Between the two angled Sections 26 extend the corrugated guideway 23 with the central locking receptacle 24.

The sliding door fitting without the guide element 20 is shown in FIG. It can be seen that a recess 31 is provided on the upper track 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 in FIGS. 8 to 10, only one 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 track 8.

In addition, the two embodiments can be combined with one another in a piece of furniture 1, in particular 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 running tracks 8 and 9 which are arranged vertically offset. It is also possible to modify the running rail with regard to the number of running tracks and their arrangement, which can also take place side by side.

Figure 11 shows a further 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 each in a groove-shaped receptacle in the joint area Track 3 are arranged. As in the previous exemplary embodiments, the running rail 3 is fixed to an upper floor of a furniture body 2.

A guide element 50 is shown in detail in FIGS. 12A to 12C. The guide element 50 is strip-shaped and has, for example, a length 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 in an opening or receptacle can be clamped or locked on the running rail 3. On the bottom 51, one or more projections 55 are also provided on the underside, which can be inserted into an opening or receptacle of the running rail 3 so that the guide element 50 is secured against displacement in the longitudinal direction.

As FIG. 12B shows in a schematic view, the base 51 consists, with respect to a horizontal plane, of a rising section, beginning from one end side in the longitudinal direction of the guide element 50, of a plateau with a uniform distance in a central region of the guide element 50 and a descending section to the opposite ge end in a longitudinal extension of the guide element 50. This shape, the bottom 51 functions functionally as the guide track 13, 14 in the first embodiment.

In addition, the wall sections 52 and 53 of the guide element 50 on their respective inner sides have a similar shape to the guide track 51, only arranged at an angle thereto. The plan view in FIG. 12B schematically shows that the two end sides of the wall sections 52 and 53 are provided with a small thickness and increase steadily in the direction of the central region of the guide element 50. A plateau with a uniform path is formed in the central area. A ramp-like structure is thus formed, which acts as a second, laterally arranged guideway 57. The formation of the guideways 57 on the wall section 52 and the wall element 53 changes the clear width of the cavity of the guide element 50 such that the cavity is narrowed in the direction of the central region 56. The guideway 57 can be formed on both wall sections 52 and 53; alternatively, an embodiment is also conceivable only for one wall section 52.

FIGS. 13A and 13B show two running rollers 7 of the two running parts 4 and 40, not shown, which are arranged at a distance from the abutting region 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 abutting area of the two sections 3a and 3b, when the roller 7 moves on the raceways 8, 9, the flanged disk 72 engages with the guide path 51 arranged on the guide element 50, which, as described above, ben is designed as a ramp-shaped structure of a floor. As a result, the roller 7 on the rising portion of the guide track 51 is gently raised until the plateau is reached, then cut on the descending portion of the bottom 51 to be lowered again.

FIGS. 14A and 14B show the rollers 7 in the region of the joint between the two sections 3a and 3b of the running rail 3. It can be seen that the rollers 7 no longer rest directly on the raceways 8 or 9 with the central section 70, but that a flanged wheel 72 rests on the guide element 50. In addition and almost simultaneously with the function of the guideway 51, the guideway 57 acts by the shape thereof following the shape of the guideway 51, only at an angle thereto, preferably rotated by 90 °. The inside of the flanged wheel 72 causes an axial movement of the roller 7 in the direction of the furniture body 2 by a stop on the guide track 57. As a result, the roller 7 maintains constant contact with the track 8, 9 when passing over the joint, the contact point resulting from the axial displacement of the roller 7 moves depending on its position to the guide member 50. As a result, the roller 7 rolls when driving over the joint on the guide track 51 from the guide element 50, but is simultaneously 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 to a vertical direction is effectively avoided here. 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 angled, with one leg being fixed to an underside of the upper floor. In this case, both a web of the running rail 3 lying on the top floor and the support device 60 can be fixed via a fastening means.

The support device 60 is shown in detail in FIGS. 15A and 15B. The support device 60 comprises a horizontal leg 61, which is fixed on the underside of the upper floor by means of fasteners, for example by screws. A vertical leg 62 of the support device 60 bears against a rear 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 is used to support the lower one Career 8 serves. On the bend 63, one or more upwardly projecting projections 64 can be formed, which support a section adjacent to a raceway 8 or pass through an opening in the running rail 3. The upper race 9 is supported by a web 67 which can be moved between a retracted assembly position (FIG. 15) and a protruding support position (FIG. 16). The web 67 is formed integrally with a slide 65, which has an elongated hole and is guided on the leg 61 via a pin 66. The web 67 passes through an opening in the leg 62 and can thus be moved into a projecting position after the mounting of the support device 60 on the furniture body 2 in order to support an area adjacent to the raceway 9, as is also shown in FIG. 14B. It can be seen that the web 67 engages under the running rail 3 in the region of the groove-shaped receptacle, into which the guide element 50 is inserted adjacent to the upper running track 9. The guide element 50 next to the lower track 8 is also inserted into a groove-shaped receptacle and is supported by the bend 63.

FIGS. 17A to 17D show the mounting of the support device. In FIG. 17A, the running rail 3 is preassembled with the two sections 3a and 3b on the upper 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 upper floor, as shown in FIG. 17B .

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 through the leg 62 from the retracted assembly position, so that the web 67 supports the guide element 50 on the running rail next to the running track 9. The assembled position of the sliding door fitting is then shown in FIG. 17D. Reference list
