Description

Guide arrangement for a sliding door, cabinet furniture and method for disassembling a guide assembly for a sliding door

The present invention relates to a guide arrangement for a sliding door, comprising a slide-mounted on a sliding guide means which is movable in a mounted position along a guide rail, and the guide means from a mounting position in which it is out of engagement with the guide rail, in the mounted position is movable, and a cabinet furniture and a method for disassembling a guide assembly.

EP 984 126 A2 discloses a guide arrangement for a sliding on a mounting rail sliding door on a cabinet with two sliding in parallel planes sliding doors are arranged in the guide means on the opposite sliding door bottom, in two adjacent guide grooves on the cabinet from below after hanging on the support rails are inserted, wherein the guide means are each arranged on a support plate, which are each inserted into a mounting plate on the sliding door rear side. Thereby, the respective guide means can be easily brought from a mounting position to an engaged position. In such a guide arrangement, however, it is disadvantageous that when disassembling the sliding door pushed out the support plate protrudes partially over the sliding door underside down from the sliding door, so that when discontinuing the suspended from the cabinet sliding door with the

Sliding door bottom on a floor the guide arrangement or the floor can be damaged. When moving, it may therefore be necessary to disassemble the guide assembly or cover the fitting parts by suitable protective measures.

Another disadvantage is that an insertion of the guide means can be done in the wrong guide groove when the guide grooves are arranged close to each other, which may be noticed only when moving the sliding doors and then requires a subsequent correction.

It is therefore an object of the present invention to provide a guide assembly and a method for disassembly of a guide assembly, which with a disassembly damage to the guide assembly or a floor is safely avoided and easy assembly and disassembly is guaranteed.

This object is achieved with a guide arrangement having the features of claim 1 and with a method for disassembling a guide arrangement having the features of claim 11.

In the guide assembly according to the invention the guide means is movable in three different positions, namely a mounted position in which the guide means is in engagement with the guide rail, a mounting position in which the guide means is out of engagement with the guide rail and therefore can be disassembled, and a Dodge position in which the guide means is disposed completely above a bottom of the sliding door. As a result, the guide means can be moved in a simple manner in a disassembled position in the assembly and then, if the sliding door is to be parked on the floor, are moved to an evasive position. This can be done manually or automatically by pushing or swiveling or other movement, so that the user is sure that when placing the sliding door a floor or the guide assembly will not be damaged.

For a simple assembly of the guide arrangement can be provided on the sliding door at least one screw or a preferably bolt-shaped fastening means on which the guide means is slidably or pivotally.

The at least one screw or the bolt-shaped fastening means is accommodated at least in the mounted position in a locking receptacle on the guide means and securely held in at least one detent position by the locking receptacle has at least one region which has a smaller width than the diameter of the at least one screw or the bolt-shaped fastener. The at least one screw or the bolt-shaped fastening means is able to pass this at least one region of lesser width as a result of the material-related elastic deformation above a certain force application, but to remain in this position below this specific application of force. It is also possible that a portion of the elastic deformation is provided by the bolt-shaped fastener, for example, in that an elastic sleeve is arranged on the bolt-shaped fastening means.

Preferably, a force storage, in particular a spring is provided to automatically move the guide means from the avoidance position to the mounting position. Then, after lifting the sliding door, the guide means can be automatically brought to the mounting position to assist the installer. Preferably, the guide means assumes the mounting position when, apart from the application of force to the force accumulator, no further force acts on the guide means.

The guide means may optionally be slidably or pivotally supported on the sliding door to be moved to the different positions. Preferably, the guide means in the mounted position can be latched, optionally also in the mounting position or the avoidance position, a locking can take place.

For a simple embodiment of the guide arrangement with only a few components, the guide means may be formed as a U-shaped molding, preferably made of plastic, which is held with a first leg on the sliding door and with the other second leg in a groove of the guide rail can be inserted , The second leg can be made shorter than the first leg in the longitudinal direction of the guide rail and / or in the vertical direction, in particular by more than 30% or 50% shorter.

Alternatively, the guide means may also be made of metal and fixed to an additional plastic holder. In this case, beads or embossments may be integrally formed on the guide means made of metal, which on the one hand have better guidance in guide rails made of plastic and thus otherwise other sliding elements, such as sliding shoes commonly used in the prior art, and on the other hand, the guide means Stiffen the metal additionally.

On the guide means also a roller can be arranged, which engages in the groove of the guide rail and whose axis of rotation is vertically aligned in the mounted position, wherein the diameter of the roller is smaller than the width of the groove of the guide rail, to make the guide particularly smooth. In order to prevent engagement in the wrong guideway with two sliding doors sliding in parallel planes with closely adjacent guideways when moving the guide means into the mounted position, the guide means for the rear sliding door may comprise a stop or a bridge dimensioned such that the Guide means can be inserted only in the associated front guideway.

The guide assembly according to the invention is preferably used in furniture, especially in a cabinet furniture.

In a method according to the invention for disassembling a guide arrangement for a sliding door, first the guide means is moved from an assembled position into a mounting position, in which the guide means is arranged out of engagement with the guide rail. Then, the sliding door is placed on a floor, wherein the guide means is moved from the mounting position to an evasive position, so that damage to the guide assembly or the floor is reliably avoided.

Under sliding doors are in the broader sense also folding doors, folding sliding doors, dividing elements or the like to understand.

The invention will be explained in more detail with reference to several embodiments with reference to the accompanying drawings. Show it:

Figures 12A to 12D show several views of another embodiment of a guide means for a guide assembly according to the first embodiment, but with closely adjacent guideways. A cupboard 1 comprises a furniture body 2, on which two sliding doors, a front sliding door 3 and a rear sliding door 4, are movably mounted in two levels in front of the furniture body 2. For this purpose, a running rail 5 is provided on a belonging to the furniture body 2 top shelf of the cabinet furniture 1, are moved to the running parts 7, so that the sliding doors 3 and 4 are arranged hanging near the top.

The figure 2 shows by the non-parallel arrangement of the sliding door 3 to the front edge of the furniture body 2 that, opposite to the top, on the back of the sliding door 3 near the bottom 40, a guide means 10 is arranged, which does not yet engage in a guide rail 8. The sliding door 3 is, as described above, arranged in a mounting position in front of the furniture body 2, that is, the running parts 7 are mounted in the running rail 5. To the Sliding door 3 and 4 to lead along the bottom 6 of the furniture body 2, the guide means 1 0 must be moved from the mounting position still in the mounted position so that it can engage in the arranged on the base 9 guide rail 8 below the bottom 6.

In the figure 3A, the guide assembly is shown in detail in the mounting position. A guide means 10 of a molded body is pivotally mounted on an inner side of the sliding door 3. The guide means 1 0 is U-shaped, with a leg 1 1 is pivotally supported on the sliding door 3 by means of a screw 14 and a leg 1 2 in a groove of a guide rail 8 can be inserted. For this purpose, the sliding door 3, as described above, initially mounted with the running parts 7 in the running rail 5. 3A, the sliding door 3 is moved towards the furniture body 2, by pivoting the guide means 10 about the screw 14, the leg 1 2 can be inserted into the groove of the guide rail 8, wherein the sliding door 3 closer to the ground 6 can be brought and thus aligned parallel to the front edge of the furniture body, as shown in Figure 3B. Now the mounted position is reached, i. the sliding door 3 is also guided on the underside in a guide arrangement, which allows a parallel guide in front of the furniture body 2. The guide rail 8 is fixed via fastening means on a base 9 of the furniture body and arranged below the bottom 6. However, a guide rail, not shown here, but also before, under or on the floor 6 are attached. The guide rail 8 may also have, instead of the step shown in Figures 3A and 3B, a slope or curve which acts as an insertion aid.

In the figures 4A to 4D, the sequence of disassembly of the guide means 1 0 is shown, for example, when the sliding door 3 has to be removed from the furniture body 2 for a move. In Figure 4A, the guide means 1 0 is still in the mounted position, wherein on the leg 1 1 an opening 1 3 (as shown in Figure 9A) is provided, which is penetrated by a screw 14 whose longitudinal axis at the same time the pivot axis for forms the guide means 10. Spaced from the opening 1 3 a Rastauf- would take 1-5 formed, which is open towards an edge of the guide means 1 0 and then extends V-shaped to an area with a smaller distance measure, resulting in the insertion of a shaft of another From a certain point of application, screw 1 6 can elastically deform the material if its shaft has a larger diameter this area happens with a smaller distance measure. Below this specific application of force, the guide means 10 is thus securely held on the screw 16 in the mounted position in the catch receptacle 15.

It is also possible that an elastic sleeve is plugged onto the screw 16, which elastically deforms when passing the V-shaped area with a smaller distance dimension, the recessed portion in the locking receptacle securely holding the guide means in the mounted position. The elastic sleeve protects the V-shaped area from damage due to sharp thread configurations on the screw 1 6, so that no special screw with special shaft must be used, but a conventional fixing screw can be used.

In order to release the guide means 10, the locking connection is achieved by the guide means 10 is pivoted about the screw 14 counterclockwise with a certain Kraftbeauf- tion, as shown in Figure 4B. In this case, the area with the smaller distance dimension is elastically deformed again and the latching receptacle 15 thus comes out of engagement with the screw 16.

Figure 4C shows how the guide means 10 is pivoted by means of an energy storage device 17, here a spring, from the mounted position to an assembly position at an angle of 135 ° +/- 10 °, in which the sliding door 3 is selectively mounted or placed on a floor can be. If the sliding door 3 is to be parked on a floor, the part of the guide means 10 projecting downwards from the sliding door 3 could damage the floor or the guide means 10 could be damaged. To avoid this, the guide means 10 can be pivoted about the screw 14 further counterclockwise against the force of the spring 17, as shown in Figure 4D. The guide means 10 is thus located completely above a bottom 40 of the sliding door 3. Both in the mounting position and in the mounted position, the guide means 10 protrudes partially below the bottom 40.

The guide means 10 is prestressed by the spring 17 from the deflection position shown in FIG. 4D into a mounting position. In the mounting position, the spring 17 is relieved and thus represents the rest of the guide element 10 should the sliding door 3 are lifted from the floor for assembly, the guide means 10 returns to a mounting position in which the guide means 10 is visible from the outside and on easy Way can be pivoted to then be locked in the mounted position.

FIG. 5 shows a modified embodiment of a guide arrangement on a furniture carcass 2 of a cupboard cabinet. A guide means 20 serves to guide the sliding door 3, which is mounted on the top again movable parts 7 movable.

The assembly of the guide means 20 is shown in Figures 6A and 6B, wherein the sliding door 3 is initially positioned so that a leg 22 of the guide means 20 is disposed below a groove of the guide rail 8. Subsequently, the guide means 20 is linearly displaced in the vertical direction from the mounting position to the mounted position, as shown by the arrow in Figure 6B. In the mounted position, the leg 22 engages in the groove of the guide rail 8 and thus ensures a guide of the sliding door third

If the guide means 20 to be dismantled, the guide means 20 is displaced from the mounted position shown in Figure 7A. On the guide means 20, two oblong holes 23 are provided with vertical alignment on the leg 21 of the guide means 20, which are each penetrated by a screw 24. The elongated holes 23 in this case have a width which is slightly larger than the diameter of the screw 24, so that the guide means 20 is held securely in the lateral and in the vertical direction. In addition, the slots 23 have approximately in the vertical center position on an area which is designed by indentations of the inner walls of the slots 23 and thus forms a latching receptacle 25. In this area, which corresponds to the mounted position, the U-shaped guide means 20 can be moved down and held securely by material-related elastic deformation in a mounting position, which is shown in Figure 7B. For this purpose, the locking forces must be overcome, since the guide means 20 is locked in the mounted position on locking receptacles 25, which cooperate with the screws 24. If the sliding door 4 is now to be parked on the ground, the guide means 20 is moved to an evasive position, which is shown in Figure 7C. For this purpose, the guide means 20 along the vertical slots 23 on the latching area in the center position further shifted upward until it is disposed completely above a bottom 40 of the sliding door 3. In Figure 8, the guide means 20 is shown in detail, which is made of a molded plastic part and is substantially U-shaped, with a leg 21 is held on the sliding door 3 and the other leg 22 is used to guide on the guide rail 8 ,

In Figure 9A, the guide means 10 is shown, which is pivotally supported on the sliding door 3. On the leg 1 1, the opening 1 3 and the locking receptacle 1 5 are formed.

In Figure 9B, a modification of the guide means 1 0 is shown, in which on the leg 1 1, a sleeve 1 8 is inserted into the locking receptacle 1 5. Through the sleeve 1 8, the locking forces for fixing the guide means 1 0 can be set more precisely. FIG. 9C shows that the sleeve 18 is designed as a separate component and can be made of metal, for example. Further, to increase the stability of a sleeve 1 9 arranged in the region of the opening 1 3, which can also be made of metal. The sleeves 1 8 and 1 9 can also be molded by injection molding on the molding. Alternatively, according to FIG. 9D, it is possible to produce the sleeves 18 and 19 by injection molding and to mold them to the molded part. Then the sleeves 18 and 1 9 can be retrofitted to the leg 1 1.

In FIGS. 10A and 10B, the guide means 10 of the first embodiment is shown again in a front view and in a sectional view taken through the center lines of the screws 14 and 16, showing that the guide means with respect to the width of the leg 12 to the leg 1 1 is designed asymmetrically and as the

Screw 14 and 1 6 engage in the sliding door 3. The asymmetrical design is designed so that the width of the leg 12, starting at the side where in the leg 1 1, the locking receptacle 1 5 is arranged, toward the side where in the leg 1 1, the opening 1 3 is arranged , Only a portion of the width of the leg 1 1, wherein the width of the leg 1 2 has at most about half of the width of the leg 1 1. The unbalanced design is required in order to pivot the leg 1 2 of the overlap with the guide rail 8, which is required in the mounted position, under the guide rail 8, which corresponds to the mounting position, in which case the leg 1 2 out of engagement with the Guide rail 8 has come. This facilitates the assembly, since the guide arrangement last lent can consist of three components, namely the two screws 14 and 1 6 and the guide means 1 0.

FIGS. 11A to 11D show a modified embodiment of a guide means 30, which, unlike the preceding embodiments, is made of a U-shaped sheet metal, which has a leg 31 on the side of the sliding door 3 as well as a Leg 32 has, which is insertable into a groove of the guide rail 8. The legs 31 and 32 are connected to each other via a bow 33, wherein the bent metal sheet can be provided with beads, profiles or other forms, on the one hand replace additional sliding elements, such as sliding shoes, and on the other hand increase the stability. The leg 31 is slidably held on a holder 34 which is fixed to the sliding door 3. The holder 34 may be fixed via one or more screws on the inside of the sliding door 3. The holder 34 has a U-shaped receptacle 35, on which the leg 31 is held displaceably, wherein the leg 31 can be latched in different positions on the holder 34. For this purpose, a latching projection 36 is provided on the holder 34, which can be inserted into various openings on the leg 31 in order to move the guide means 30 from a mounting position to an assembled position or from the mounting position to an evasive position.

FIGS. 12A to 12D show a plurality of views of a further embodiment of a guide means 50 for a guide arrangement according to the first embodiment on a rear sliding door 4, but with closely adjacent guideways of a two-track guide rail 60. In addition to all features of the guide means 10 already described above, is additionally arranged on the guide means 50 an L-shaped, angular or C-shaped web 53 on the leg 51, which forms a stop and ensures that the leg 52 can be pivoted during assembly only in the front guide track 62. As a result, incorrect assembly of the leg 52 in the rear guide track 61 is prevented. The depth distance between the surface of the web 53 and the outer surface of the leg 52 is greater than, equal to, the horizontal distance from the front of the guide rail 60, in which the web 53 comes into abutment in the mounting position, to the front of the central web executed, on the one hand when pivoting in the mounted position incorrect assembly in the rear guide track 61 and on the other hand, a contact in the mounted position contact with the front of the guide rail 60 to avoid. For ease of assembly, the leg 52 still on the upper edges in the overlap region with the guide rail 62 correspondingly designed radii or chamfers. The L-shaped or C-shaped web 53 is on the side where the opening 13, so the pivot axis is located below this and formed with respect to the vertical leg only so long that this in the mounted position, at least immediately below the Top edge of the leg 52 ends.

In the illustrated embodiment, the guide means 10, 20, 30 and 50 are U-shaped. It is also possible to produce the guide means in a different geometry, so that they can be moved along a guide rail 8.
