Description

Guide device for a sliding element, piece of furniture and method for assembling a sliding element

Technical Field

The invention relates to a guide device for a sliding element, comprising a guide rail having at least one groove, in which a guide element that can be fixed to the sliding element can be introduced, wherein the guide element is held on a support such that it can be adjusted transversely to the longitudinal direction of the guide rail toward the base of the groove and such that it can be fixed in different positions relative to the base of the groove, and actuating means are provided for moving the guide element from a movable adjustment position to a fixed position, and to a piece of furniture and a method for assembling the sliding element.

Background

DE 102013111482 a1 discloses a guide device for a sliding door, wherein the guide rail has a downwardly open groove into which a guide element connected to the sliding door can be inserted. The height of the guide elements cannot be adjusted, so that for reasons of tolerance compensation it is necessary to make the grooves relatively deep to ensure a lateral overlap of the guide elements. For stable guidance, long groove walls must therefore be provided on the rail, which requires high material requirements and is also visually unattractive.

DE 19653897B 4 discloses a guide device for a door element, in which a downwardly open groove is formed on a guide rail, into which a projection of the guide element can be inserted. The guide element may be fixed to the bracket in a height-adjustable manner. This allows the length of the groove wall to be reduced, as the adjustment mechanism allows for adaptation during installation. However, a disadvantage is that grinding may occur on the groove base when the projection is located in the groove, in particular in the mounted position when the projection has come into contact with the groove base. This results in sliding noise and higher actuation forces due to friction.

Disclosure of Invention

It is therefore an object of the present invention to provide a guide device for a sliding element, a piece of furniture having such a guide device and a method for assembling a sliding element, in which the guide element can be simply aligned on a groove of a guide rail, wherein the above-mentioned disadvantages are avoided.

This object is achieved by a guide device having the features of claim 1, a piece of furniture having the features of claim 12 and a method having the features of claim 13.

In the guide device for a sliding element according to the invention, the guide element can be held adjustably on the bracket transversely to the longitudinal direction of the guide rail towards the base of the groove, wherein the guide element can be moved away from an abutment position on the base of the groove by means of the actuating device, thereby fixing the guide element at a distance from the base of the groove. The actuating device thus allows, on the one hand, the guide element to be spaced apart from the base of the groove and, on the other hand, to be fixed. By using the base as a reference surface, tolerances can be compensated for by the adjustment mechanism and a predetermined distance to the base of the groove can be set by the actuating means, irrespective of whether the guide rail is fixed into the furniture body with higher or lower tolerances. This ensures that: lateral support of the guide element by the wall of the recess is reliably ensured by achieving the greatest possible overlap of the guide element in the wall of the recess. In this case, the walls of the recess can be made shorter, since defined mounting conditions can be more easily obtained.

When the actuating means are actuated from the adjustment position to the securing position, it is preferred that the guide element is moved away from the base of the groove at the same time. This allows the movement of the actuating means to be used for fixing and adjusting the guide element.

For ease of assembly, the guide element may be preloaded towards the base of the groove by an accumulator, preferably a spring. During assembly, the guide element may then be supported on the base of the groove such that, when moving the actuating device from the adjustment position to the fixing position, a defined distance, for example, in the range of 0.5mm to 4mm, in particular in the range of 1mm to 3mm, is produced between the base of the groove and the guide element.

For ease of actuation, the actuation device may comprise a pivotable actuation section, wherein the actuation device is rotatable from an adjustment position to a fixation position. The actuating means may be actuated manually when the mounted sliding element is stationary or automatically when the sliding element is moved by an actuator fixed to the furniture body to ensure that the guide element is in a fixed position when the sliding element is moved after the actuating means has been activated.

In order to precisely align the guide element, it can be continuously adjusted relative to the holder. The actuating device may comprise a sleeve on or in which at least one running-off profile with a pitch is formed. The running separation profile is arranged helically around the rotational axis of the sleeve. Preferably, the at least one running separating contour is arranged at an end face of the sleeve. Due to the path movement of the points on the at least one running separation profile around the rotational axis of the sleeve, the guide element is moved in the direction of the rotational axis of the sleeve over a distance which depends on the pitch. Finally, rotation of the sleeve causes displacement of the guide element away from the base of the groove. Furthermore, the actuating device preferably has a smooth-walled adjustment section which in the adjustment position faces the profiled section on the holder and in the securing position the locking section on the actuating device engages with the profiled section, so that in the adjustment position a displacement of the guide section can be achieved, which in the securing position is prevented by the locking section.

It is also conceivable to design the running separation profile as a single-start thread or as a multiple-start thread on the circumference of the sleeve with a pitch. In this case, such a thread with self-locking itself or other suitable means not described in detail here can ensure that an unintentional adjustment from the adjustment position to the fixing position takes place.

For a compact design, the bracket may be substantially plate-shaped, so that it can be mounted on the rear wall of the sliding element. It is also possible to provide a guide means on the carriage to guide the guide element linearly on the carriage. The guide element can be formed in a U-shaped manner, wherein a guide section which can be inserted into the groove is provided on the first leg and a section which is guided on the bracket is provided on the second leg. By varying the distance between the two legs, the guide element can be used for either the front or the rear slide element.

According to the invention, the guide device is used for furniture, in particular for sliding elements. However, it is also possible to use the guide means for folding sliding elements, partition walls or other linearly movable parts.

In the method according to the invention for assembling a sliding element, the guide element is first positioned in the vicinity of the groove of the guide rail, so that the guide element is then moved against the force of the accumulator, preferably a spring, and a portion of the guide element is passed into the groove, wherein the guide element is in contact with the base of the groove. The guide element is then fixed in the groove by means of the actuating means, wherein the guide element is moved away from the base of the groove by moving the actuating means. This allows to precisely adjust the distance between the base of the groove and the guide element, so that the overlap in the groove can be maximized and tolerances can be easily compensated.

For ease of assembly, the actuating means for securing the guide element may be pivoted such that the guide element is lifted from the base of the groove during pivoting.

Detailed Description

The piece of furniture 1 comprises a furniture body 2 on which a rear slide element 3 and a front slide element 4 are movably mounted. It is also possible to provide more than two sliding

elements

3 and 4 on the furniture body 2. The sliding

elements

3 and 4 are suspended on bearing rails on the top plate, wherein the guide rail 6 is arranged on the base of the furniture body 2, so that the front sliding element 4 is guided by means of the guide element 8' via the first guide means 7. The rear slide element 3 is guided via a second guide means 5 by means of a guide element 9, the second guide means 5 functioning in the same way as the guide means 7.

In fig. 2, the

guide devices

5 and 7 are shown in a partial section of the piece of furniture 1 according to line II-II. The guide rail 6 is fixed to the furniture body 2 in the region of the base and has two downwardly facing

grooves

60 and 61. The guide section 80 of the guide element 8 is arranged in the groove 60 close to the furniture carcass 2. The guide element 8 has a U-shaped cross section and is fixed to the bracket 10 on the rear side of the sliding element 4 on the side facing away from the guide section 80. In a similar manner, the guide section 90 is inserted into the groove 61 of the guide element 9, wherein the guide element 9, which is U-shaped in cross section, is fixed to the bracket 10 on the rear side of the sliding element 3 by means of the second leg.

Fig. 2 shows the

guide sections

80 and 90 inserted into the

grooves

60 and 61 of the guide rail 6, but the

guide elements

8 and 9 have not yet been positioned and fixed. For this purpose, an actuating device 20 is provided on each

guide element

8 and 9, which actuating device 20 can be moved from an adjusting position to a fixing position.

In fig. 3, the actuating means 20 on the

guide elements

8 and 9 are moved to a fixed position. By adjusting the actuating device 20, the

guide sections

80 and 90 are moved away from the base 63 of the

grooves

60 and 61, respectively, by a predetermined amount, so that a small gap 62 is formed in the

grooves

60 and 61 in the vertical direction, which gap lies, for example, in the range of 0.5mm to 4mm, so that friction noise is reliably avoided when moving the sliding

elements

3 and 4.

Fig. 4 shows the guide means 5 in detail. The guide device 5 comprises a plate-shaped bracket 10, which plate-shaped bracket 10 can be mounted on the sliding element 3 and has an opening 11, which opening 11 can be accessed for assembling a fastening screw. Two strip-shaped guide portions 12 project from the carrier 10, so that the guide element 9 is guided linearly in the vertical direction on the carrier 10. Furthermore, a projecting support element 13 is formed on the support 10, on which support 10 one end of the energy store designed as a spring 30 is supported. In the central region of the carrier 10, a profiled section 14 with teeth is also formed, by means of which the guide element 9 can be fixed in a fixed position.

The guide element 9 has a U-shaped cross section and comprises a guide section 90, which guide section 90 can be inserted into the groove 61 of the guide rail 6. The guide section 90 is connected to the leg 92 via a transverse web 91, the transverse web 91 being guided linearly on the bracket 10. Two guide rails 95 are formed on the lower section of the leg 92, which can be inserted into corresponding strip-like receptacles on the guide section 12. A recess 94 is also provided in the leg 92, and the spring 30 is inserted into the recess 94. The spring 30 is supported at the upper end at the stop 97 of the recess 94 and at the lower end at the support element 13 of the carrier 10, so that the guide element 9 is pretensioned upwards at the carrier 10. Furthermore, a further recess 93 is formed on the leg 92, on which further recess 93 a spiral-shaped counter-contour 82 extending in the vertical direction with a spacing is formed at the upper and lower edge, as can be seen in more detail in fig. 8.

The guide means 5 further comprise actuating means 20 for moving the guide element 9 from the adjustment position to the fixation position. The actuating device 20 comprises a rotatably mounted actuating section 21 and a lever 22, the lever 22 being non-rotatably connected with a sleeve 23 of the actuating device 20. The sleeve 23 is again rotatably held or mounted in the recess 93 of the holder 10.

The sleeve 23 is shown in detail in fig. 5A and 5B. A receptacle 24 is formed in the sleeve 23, which engages the rod 22 in a rotationally fixed manner, whereby for this purpose the rod 22 and the receptacle 24 are formed with the same cross-sectional profile, for example square. The sleeve 23 comprises a smooth-walled adjustment section 26 and a locking section 25 at the outer periphery. In the adjustment position the smooth-walled adjustment section 26 is located opposite the profiled section 14 on the carrier 10, while in the fixing position the locking section 25 engages with the profiled section 14 to prevent vertical movement of the guide element 8 relative to the carrier 10. At the end face of the sleeve 23, rising running

separation contours

27a and 27b are arranged, which are formed helically or spirally around the rotational axis of the sleeve 23.

Fig. 6A to 6F show the guide device 5 in the adjustment position. In the adjustment position, the spring 30 presses the guide element 9 upwards until the guide section 90 rests against the base of the groove 61. Since the smooth-walled adjustment section 26 of the sleeve 23 is arranged on the carrier 10 opposite the profiled section 14, the guide element 9 can be freely moved in the vertical direction. The actuating device 20 is in an adjusting position, in which the actuating section 21 is held on a locking element 96, the locking element 96 being formed on the underside of the transverse web 91.

If the guide element 5 is to be moved to a fixed position, the actuating section 21 is pivoted, as shown in a comparison of fig. 6F and 7D. Fig. 7A to 7E show the guide 5 in a fixed position.

By pivoting the actuating device 20 on the actuating section 21, the sleeve 23 of the actuating device 20 is rotated, thereby moving the smooth wall adjusting section 26 along the profiled section 14 such that the contour of the locking section 25 engages with the profiled section 14. Because of the inclination during rolling of the running

separating profiles

27a and 27b arranged helically about the axis of rotation of the sleeve 23 on the mating profiles 82 of the legs 92, the rotational movement of the sleeve 23 not only produces a fixing, but also an adjusting movement of the guide element 9 relative to the bracket 10, as a result of which the guide element 9 also moves vertically downwards. This produces a height adjustment of the guide element 9 away from the base 63 of the slot 61 by rotating the actuating means 20. In this case, the guide element 9 is displaced in the direction of the axis of rotation of the bush 23 by a distance which depends on the path of displacement of the point on the running

separation profile

27a or 27b about the axis of rotation of the bush 23. The adjustment in the vertical direction, i.e. in the direction of the axis of rotation of the sleeve 23, may be slight to ensure that the end face of the guide section 90 does not rub against the base of the groove 61. When the locking section 25 engages with the profiled section 14, the guide element 9 can no longer move along the holder 10, so that the position of the guide element 8 is fixed.

Fig. 8 shows the guide means 7 for the front slide element 4 in detail. The guide means 7 are designed similarly to the guide means 5, with the difference that the design of the guide element 8 is different, because the distance between the leg 92 and the guide section 80 is larger compared to the guide means 5. The guide section 80 is connected to the leg 92 via a transverse web 81. In the recess 93, in an upper region and in a lower region (not shown), a helical counter-profile 82 is formed, which extends in the vertical direction and interacts with the running separating profile on the sleeve 23, as already described. In all other respects, the guide means 7 correspond to the guide means 5.

Fig. 9A to 9D show the guide device 7 in the adjustment position. In this position, the guide section 80 is vertically movable relative to the stent 10, as described above. In order to move the guide device 8 from the adjustment position into the fixing position, the actuating section 21 of the actuating device 20 is pivoted, whereby the locking section 25 engages with the profiled section 14, wherein at the same time the guide section 80 is moved slightly downward relative to the bracket 10, for example between 0.5mm and 4mm, due to the rotational movement of the running

separation contour

27a or 27b arranged on the sleeve 23.

Fig. 11A to 11D show the assembly of the guide means 5 for the rear slide element 3. The sliding element 3 is first attached to the bearing rail on the top plate of the furniture body 2 and the guide element 9 is positioned in the vicinity of the

grooves

60 and 61 of the guide rail 6, as shown in fig. 11A. The sliding element 3 can be placed on the floor in this position without damaging the guide element 9, wherein the guide element 9 and the bracket 10 can be arranged above the lower end edge of the sliding element 3 such that no protruding parts are provided on the sliding element 3.

For the assembly of the sliding element 3, the guide element 9 is moved downwards against the force of the spring 30, as shown in fig. 11B. As a result, the guide section 90 is located below the downwardly open groove 61 of the guide rail 6, and the guide section 90 can now be passed into the groove 61, as shown in fig. 11C. The guide element 9 can now be released so that one end face of the guide section 90 abuts against the base 63 of the groove 61. Here, the base 63 serves as a reference surface for disengagement of the guide member 9 described below.

After the guide element 9 has been aligned as shown in fig. 11C, the guide element 9 is moved from the adjustment position to the fixing position by pivoting the actuating means 20 on the actuating section 21. By pivoting the actuating device 20, the guide element 9 is moved slightly downwards by a predetermined amount as specified by the gradient of the running-

separation profiles

27a and 27b during running separation in the recess 93. After a certain rotation of the sleeve 23, the profiled section 14 arranged on the sleeve 23 engages with the locking section 25 on the holder 10, which locks the sleeve 23 and thus the guide element 9 as a whole on the holder 10 and the guide device 5 is fixed in the vertical direction. Finally, a small gap 62 is formed between the end face of the guide section 90 and the base of the groove 61.

Fig. 12A and 12B show a modified exemplary embodiment of the guide device, in which a modified guide element 9' is used, which is otherwise designed as shown in fig. 4, with the difference that a recess 98 is formed in the region of the guide section 90, in which recess 98 a guide roller 99 is rotatably mounted. The guide roller 99 is formed in a cylindrical shape and protrudes laterally above the guide section 90. The guide rollers 99 are mounted to rotate about a vertical axis and prevent the guide sections 90 from contacting the side walls of the groove 61. This results in less friction when moving the sliding element 3.

In fig. 12C, the guide element 9' of fig. 12A and 12B has been modified in that two guide rollers 99 are provided in the recess 98 on the guide section 90 instead of one guide roller 99. Both guide rollers 99 have vertical rotation axes and reduce friction when moving the slide member 3. In this case, the guide rollers 99 may be aligned or offset in a plane parallel to the longitudinal direction of the guide rail 6 to ensure optimal guidance.

Fig. 13A and 13B show a modified exemplary embodiment in which the actuating device 20 with the actuating section 21 is not pivoted manually but by means of an activator. For this purpose, an activator 40 is mounted near the guide rail 6, which may be designed, for example, as a parallelepiped component, which may be chamfered on the side facing the actuating section 21. When moving the sliding element 3, the actuating section 21 now meets the chamfered side, pivoting the actuating section 21 from the adjustment position (fig. 13A and 13B) to the fixing position (fig. 13C). By installing the pre-assembled activator 40, incorrect assembly can be safely avoided. It is particularly advantageous if only one guide 5 or 5 'or 7' is arranged on the sliding element 3 and/or 4.

Fig. 14 shows an exemplary embodiment in which the guide rail 6' is not arranged on the base of the furniture carcass 2 but on the top panel. The groove on the guide rail 6' is formed to be open downward, and the guide section 70 of the guide element engages into the groove. The guide section 70 remains adjustable on the guide device 5', wherein the guide device 5' has an actuating device 20 'to enable adjustment of the guide section 70 relative to the groove of the guide rail 6', as has already been described in the preceding exemplary embodiment. However, the guide section with the guide section 70 is not U-shaped, but rather is elongated or web-shaped.

In the exemplary embodiment of fig. 14, the sliding door 3 is supported by at least one running section on a floor (floor), which can be moved in a sliding rail 72 via rollers 71.

It is also possible to provide synchronization between a plurality of guide means 5 or 7 on the sliding

element

3 or 4, so that by actuating the actuating means 20 the

guide elements

8, 9 or 9' are simultaneously moved from the adjustment position to the fixing position. This synchronization can take place, for example, via cable pulls or links.
