Description

Sliding door guide, cabinet and method for dismounting sliding door guide

Technical Field

The present invention relates to a sliding door guide and to a cabinet and a method for dismounting the guide.

Background

EP 984126 a2 discloses a guide device for a sliding door suspended from above on a supporting rail on a cupboard, with two sliding doors which are movable in parallel planes, wherein guide means are provided on the underside of the opposite sliding door which, after being suspended on the supporting rail, can be pushed from below into two side-by-side guide grooves on the cupboard, wherein the guide means are provided in each case on a support plate which can be pushed in each case into a fastening plate on the rear side of the sliding door. The corresponding guide means can thus be easily brought from the assembly position into the engagement position. However, it is disadvantageous in such a guide arrangement that, when the sliding door is being disassembled, the pushed-out support plate protrudes downwardly from the sliding door distributed over the underside of the sliding door, so that the guide arrangement or the base plate can be damaged when the sliding door suspended from the cabinet rests with the underside of the sliding door on the base plate. It may therefore be necessary to remove the guide or to cover the fitting with suitable protective measures when moving.

It is also disadvantageous that, when the guide grooves are arranged closely next to one another, the guide means can be pushed into the wrong guide groove, which can only be detected when the door is slid and subsequently needs to be corrected.

Disclosure of Invention

The object of the invention is therefore to provide a guide device and a method for removing a guide device, whereby damage to the guide device or the base plate is reliably avoided during removal and easy assembly and removal are ensured.

This object is achieved with a guide device according to one aspect of the invention and with a method for dismounting a guide device according to another aspect of the invention.

In the guide arrangement according to the invention, the guide means can be moved in three different positions, namely an installed position in which the guide means engages the guide rail; an assembly position in which the guide mechanism is disengaged from the guide rail and can therefore be disassembled; and an escape position in which the guide mechanism is disposed entirely above a lower side of the sliding door. The guide mechanism can thus be moved in a simple manner into the assembly position during disassembly and subsequently into the retracted position as soon as the sliding door is to be parked on the base plate. This can be done manually or also automatically by pushing or pivoting or other movements, so that the user safely leaves the floor or the guide device undamaged when parking the sliding door.

For simple assembly of the guide device, at least one screw or preferably screw-shaped fastening means can be provided on the sliding door, on which the guide means is held displaceably or pivotably.

The at least one screw or screw-like fastening means is in this case accommodated, at least in the mounted position, in a latching accommodation on the guide means and is held securely in at least one latching position in which the latching accommodation has at least one region with a width which is smaller than the diameter of the at least one screw or screw-like fastening means. At least one screw or screw-like fastening means can pass through at least one region of smaller width by being subjected to an elastic deformation of the material above a certain force application, but can catch in this position below a certain force application. It is also possible that the elastically deformable part is provided by a screw-like fixing mechanism, for example in the form of: the elastic sleeve is arranged on the screw-shaped fixing mechanism.

Preferably, a force store, in particular a spring, is provided in order to move the guide mechanism automatically from the retracted position into the installation position. Thus, the guide mechanism can be automatically placed in the fitting position after lifting the slide door, thereby assisting the fitter. Preferably, the guide means here assumes the installation position when no further forces act on the guide means irrespective of the force application of the force store.

The guide mechanism is selectively movably or pivotably held on the sliding door so as to be moved to different positions. Preferably, the guide mechanism can be latched in the installed position, wherein latching can also take place optionally in the installation position or in the escape position.

For a simple construction of the guide device with only few components, the guide means can be designed as a U-shaped profile, preferably made of plastic, which is held on the sliding door by a first leg and can be inserted into the groove of the guide rail by a second, further leg. The second leg is configured, in the longitudinal direction of the rail and/or in the vertical direction, shorter than the first leg, in particular more than 30% or 50% shorter,

alternatively, the guide mechanism can also be made of metal and fixed to an additional holder made of plastic. In this case, recesses or moldings can be molded onto the metal holding means, which on the one hand have a better guidance in the plastic guide rail and can therefore also replace other sliding elements (such as sliding shoes which are customary in the prior art), while on the other hand additionally reinforcing the metal holding means.

The guide mechanism can also be provided with rollers which engage in the grooves of the guide rail and the axes of rotation of which are oriented vertically in the installed position, wherein the diameter of the rollers is smaller than the width of the grooves of the guide rail, so that the guide is particularly smooth.

In order to prevent engagement in the wrong guide rail when the guide mechanism is moved into the installed position in sliding doors with closely juxtaposed guide rails that are movable in two parallel planes, the guide mechanism for the rear sliding door can have a stop or a lug, which is dimensioned such that the guide mechanism can only be guided into the relevant front guide rail.

The guiding device according to the invention is preferably used in furniture, in particular in cabinets.

In the method according to the invention for dismounting a sliding door guide, the guide means are first moved from the mounted position to the mounting position, in which the guide means are disengaged from the guide rail. The sliding door is then resting on the base plate, wherein the guide mechanism is moved from the assembly position into the retracted position, so that damage to the guide device or the base plate is reliably avoided.

A sliding door is also understood to be a folding door, a folding sliding door, a separating element, etc. in a broad sense.

Detailed Description

The cabinet 1 comprises a furniture body 2 on which two sliding doors, a front sliding door 3 and a rear sliding door 4, are movably supported in two planes in front of the furniture body 2. For this purpose, on the upper base plate of the cabinet 1 belonging to the furniture body 2, a sliding track 5 is provided, on which a slider 7 can be moved, so that the sliding doors 3 and 4 are arranged in a suspended manner in the vicinity of the upper side.

Fig. 2 shows the non-parallel arrangement of the sliding door 3 relative to the furniture carcass 2, in contrast to the upper side, on the rear side of the sliding door 3 in the vicinity of the lower side 40, a guide mechanism 10 is provided which is not yet engaged in the guide rail 8. The sliding door 3 is arranged in the assembled position before the furniture carcass 2, as described above, i.e. the slider 7 is suspended in the sliding rail 5. In order to guide the sliding door 3 or 4 along the floor 6 of the furniture carcass 2, the guide mechanism 10 must be moved from the assembly position into the mounted position so that it can engage under the floor 6 into the guide rail 8 provided on the base 9.

The guide means in the assembled position is shown in detail in fig. 3A. A guide mechanism 10, which is formed from a molded body, is pivotably supported on the inside of the sliding door 3. The guide mechanism 10 is designed in the form of a U, wherein the legs of the sliding door 3 are held pivotably by means of screws 14 and the legs 12 can be inserted into the grooves of the guide rail 8. For this purpose, the sliding door 3 is first suspended in the sliding rail 5 by means of the slider 7, as described above. The sliding door 3 according to fig. 3A is then moved towards the furniture carcass 2. By pivoting the guide mechanism 10 about the screw 14, the leg 12 can engage in a groove of the guide rail 8, wherein the sliding door 3 can be guided here close to the floor panel 6 and thus oriented parallel to the front edge of the furniture carcass, as is shown in fig. 3B. The mounted position is now reached, i.e. the sliding door 3 is guided on the underside in a guide device which enables a parallel guidance of the furniture carcass 2. The guide rail 8 is fixed to a base 9 of the furniture body via a fixing mechanism and is disposed below the floor panel 6. However, the guide rails not shown here can also be fixed in front of, below or on the base plate 6. Instead of the step shown in fig. 3A and 3B, the guide rail 8 can also have an inclined or rounded portion, which serves as an insertion aid.

Fig. 4A to 4D show the removal of the guide mechanism 10, for example when the sliding door 3 has to be removed from the furniture carcass 2 for the purpose of moving a house. In fig. 4A, the guide mechanism 10 is also in the mounted state, wherein an opening 13 is provided on the leg 11 (as is also shown in fig. 9A), said opening being pierced by a screw 14, the longitudinal axis of which simultaneously forms the pivot axis for the guide mechanism 10. Spaced apart from the opening 13, a latch receptacle 15 is formed, which is open toward the edge of the guide 10 and then extends in a V-shape toward a region with a smaller gap, which can be elastically deformed depending on the material, from a certain force application, when the shank of the further screw 16 is inserted: the rod of the other screw, which has a larger diameter, passes through a region with a smaller clearance. The guide means 10 on the screw 16 is thus reliably held in the installed position in the latch holder 15 with a defined force application.

It is also possible for an elastic sleeve to be plugged onto the screw 16, said sleeve being elastically deformed when passing through the V-shaped region with a smaller gap, wherein the return deformation in the latch receiver holds the guide reliably in the installed position. The elastic sleeve protects the V-shaped region from damage by sharp thread formations on the screw 16, so that no special screws with expansion rods are necessary, but instead common set screws can be used.

To release the guide mechanism 10, the latching connection is released by: the guide mechanism 10 is pivoted with a defined force application about the screw 14 in the counterclockwise direction, as shown in fig. 4B. In this case, the region with the smaller gap is again elastically deformed and the detent receiver 15 is thus disengaged from the screw 16.

Fig. 4C shows how the guide mechanism 10 is pivoted by means of the force store 17 (here a spring) from the mounted position through an angle of 135 +/-10 into the mounting position in which the sliding door 3 is selectively mounted or can be parked on the floor. If the sliding door 3 is to be parked on the floor, the portion of the guide mechanism 10 protruding downward from the sliding door 3 may damage the floor or the guide mechanism 10 may be damaged. To avoid this, the guide mechanism 10 can be pivoted about the screw 14 further against the clockwise direction against the force of the spring 17, as shown in fig. 4D. The guide mechanism 10 is thus completely above the underside 40 of the sliding door 3. The guide mechanism 10 projects partly from the underside 40, both in the assembled position and in the mounted position.

The guide mechanism 10 is here pretensioned by a spring 17 from the retracted position shown in fig. 4D into the installation position. In the assembled position, the spring 17 is released and is therefore approximately the rest position for the guide element 10. If the sliding door 3 is to be lifted from the floor for installation, the guide mechanism 10 is brought back into the assembly position, in which the guide mechanism 10 is visible from the outside and can be pivoted in a simple manner so as to then snap into the installed position.

Fig. 5 shows a modified embodiment of the guide device on the furniture body 2 of the cabinet. The guide mechanism 20 serves to guide the sliding door 3, which is in turn movably supported on the upper side via the slide 7.

The installation of the guide mechanism 20 is shown in fig. 6A and 6B, wherein the sliding door 3 is first positioned such that the leg 22 of the guide mechanism 20 is disposed below the slot of the guide rail 8. Next, the guide mechanism 20 is linearly moved in the vertical direction from the fitting position to the mounted position, as indicated by the arrow in fig. 6B. In the mounted position, the leg 22 engages in a groove of the guide rail 8 and is therefore responsible for the guidance of the sliding door 3.

If the guide mechanism 20 is to be removed, the guide mechanism 20 is moved out of the installed position shown in FIG. 7A. On the guide mechanism 20, two elongated holes 23 are provided in a vertical orientation on the leg 21 of the guide mechanism 20, which elongated holes are each penetrated by a screw 24. The elongated hole 23 has a width in this case which is slightly larger than the diameter of the screw 24, so that the guide mechanism 20 is reliably held in the lateral direction and the vertical direction. Furthermore, the elongated hole 23 has, approximately in the vertical center position, a region which is formed by recessing the inner wall of the elongated hole 23 and thus forms the latch receiver 25. In the region corresponding to the installed position, the U-shaped guide 20 can be moved downward into the installation position and is held securely by being subjected to elastic deformation of the material, as shown in fig. 7B. For this purpose, the latching force must be overcome, since the guide means 20, in the installed position, latches onto the latching receptacles 25, which interact with the screws 24.

If the sliding door 4 is now to be parked on the floor, the guide mechanism 20 is moved into the retracted position, which is shown in fig. 7C. For this purpose, the guide means 20 is moved further upward along the vertical slot 23 via the latching region in the intermediate position until it is completely arranged above the underside 40 of the sliding door 3.

Fig. 8 shows the guide mechanism 20 in detail, which is made of a molded part made of plastic and is formed substantially in a U shape, the leg 21 being held on the sliding door 3 and the lower leg 22 being used for being guided on the guide rail 8.

In fig. 9A, a guide mechanism 10 is shown, which is pivotably held on the sliding door 3. The leg 11 has an opening 13 and a locking receptacle 15.

Fig. 9B shows a modification of the guide mechanism 10, in which the sleeve 18 is inserted into the latch receptacle 15 on the leg 11. The latching force can be adjusted more precisely by the sleeve 18 to secure the guide mechanism 10. Fig. 9C shows that the sleeve 18 is formed as a separate component and can be made of metal, for example. In addition, for increased stability, a sleeve 19, which can likewise be made of metal, is provided in the region of the opening 13. The

sleeves

18 and 19 can also be injection-molded onto the molded part in an injection-molding process.

Alternatively, it is possible according to fig. 9D for the

sleeves

18 and 19 to be produced in an injection molding process and to be molded onto the molded part. The

sleeves

18 and 19 can then be mounted afterwards on the leg 11.

The guide mechanism 10 of the first embodiment is also shown in a side view and in a cross-sectional view through the midline of the

screws

14 and 16 in fig. 10A and 10B, wherein: the guide mechanism is asymmetrically configured in terms of the width of the leg 12 from the leg 11 and how the

screws

14 and 16 engage into the sliding door 3. The asymmetrical design is implemented such that the width of the leg 12, starting from the side of the leg 11 on which the latch receptacle 15 is arranged toward the side of the leg 11 on which the opening 13 is arranged, is only a fraction of the width of the leg 11, wherein the width of the leg 12 is at most approximately half the width of the leg 11. An asymmetrical configuration is necessary so that the leg 12 can be pivoted away from covering with the rail 8 below the rail 8, corresponding to the assembly position in which the leg 12 is disengaged from the rail 8, having to be covered in the mounted position as described above. This makes the installation easy, since the guide device can finally consist of three parts, namely the guide mechanism 10 and the two

screws

14 and 16.

Fig. 11A to 11D show a modified embodiment of a guide mechanism 30, which, unlike the preceding exemplary embodiment, is produced from a U-shaped sheet metal and has legs 31 on the side of the sliding door 3 and legs 32 which can engage in grooves of the guide rail 8. The

legs

31 and 32 are connected to each other via a base plate 33, wherein the bent metal plate can be provided with grooves, profiles or other shapes, which on the one hand replace additional sliding elements such as sliding guide shoes and on the other hand improve the stability. The leg 31 is movably held on a holder 34 fixed to the sliding door 3. The holder 34 may be fixed on the inner side of the sliding door 3 via one or more screws. The holder 34 has a U-shaped receptacle 35 on which the leg 31 is held movably, wherein the leg 31 snaps into place on the holder 34. For this purpose, latching projections 36 are provided on the holder 34, which can be inserted into different openings in the leg 31, so that the guide mechanism 30 can be moved from the mounting position into the mounted position or from the mounting position into the retracted position.

Fig. 12A to 12D show a number of views of another embodiment of a guide mechanism for a guide arrangement according to the first embodiment, but with a dense side-by-side rail of the double-rail guide rails 60. In addition to all the features of the guide mechanism 10 described, an L-shaped, angled or C-shaped lug 53 is additionally provided on the leg 51 on the guide mechanism 50, which lug forms a stop and ensures that the leg 52 can only be pivoted into the front guide rail 62 during installation. This prevents the leg 52 from being erroneously mounted on the rear rail 61. The depth distance between the surface of the web 53 and the outer surface of the leg 52 is designed here to be greater than, at most equal to, the horizontal distance of the front side of the guide rail 60, on which the web 53 rests in the assembled position, up to the front side of the intermediate position, in order on the one hand to avoid incorrect installation into the rear guide rail 61 when pivoted into the installed position and on the other hand to avoid contact with the front side of the guide rail 60 in the installed position. For easier mounting, the leg 52 has a radius or a chamfer at the upper edge, which is correspondingly configured in the region of the footprint with the guide rail 62. The L-shaped or C-shaped web 53 is arranged below the opening 13, i.e. on the side where the pivot axis is located, and is only configured to be so long in the vertical leg that, in the mounted position, it is at least directly below the upper edge of the leg 52.

In the illustrated embodiment, the guide means 10, 20, 30 and 50 are formed in a U-shape. It is also possible that the guide means is manufactured in other geometrical shapes so that it is movable along the guide rail 8.
