Description

 Guide device for a sliding element, furniture and method for mounting a sliding element

The present invention relates to a guide device for a sliding element having a guide rail with at least one groove, in which a fixable on a sliding element guide element can be inserted, wherein the guide element is held transversely to the longitudinal direction of the guide rail to a bottom of the groove adjustable on a holder and in different positions relative to the bottom of the groove is fixable, and an actuating device is provided to bring the guide member from a movable adjustment position to a fixed position, and a furniture and a method for mounting a sliding element.

DE 10 2013 1 1 1 482 A1 discloses a guide device for a sliding door, in which a rail has a downwardly open groove into which a guide element can be inserted, which is connected to a sliding door. The guide element is not adjustable in height, so that it is necessary for reasons of tolerance compensation, the groove comparatively deep to ensure a lateral overlap of the guide element. For a stable guide, it is therefore necessary to provide long groove walls on the rail, which requires a high material requirement and is also visually less appealing.

DE 196 53 897 B4 discloses a guide arrangement for a door element, in which a downwardly open groove is formed on a guide rail into which a projection of a guide element can be inserted. The guide element can be fixed in height to a holder. As a result, the length of the groove walls can be reduced because an adjustment during assembly is possible via an adjustment mechanism. However, there is the disadvantage that, when the projection is positioned in the groove, grinding can occur on the groove bottom, in particular if the projection bears against the groove bottom already in the mounting position. This leads to sliding noises and higher actuation forces due to friction.

It is therefore an object of the present invention to provide a guide device for a sliding element, a piece of furniture with such a guide device and a method for assembling a sliding element, in which an ne simple alignment of the guide element on a groove of a guide rail is possible, with the above-mentioned disadvantages are avoided.

This object is achieved with a guide device with the features of claim 1, a piece of furniture with the features of claim 1 2 and a method having the features of claim 1 3.

In the guide device according to the invention for a sliding element, a guide element is held transversely to the longitudinal direction of the guide rail to a bottom of the groove adjustable on a holder, via an actuating device, the guide element is moved away from an adjacent position at the bottom of the groove to the guide element spaced from the bottom of the groove to fix. By the actuating device can thus be effected on the one hand, a spacing of the guide element from the bottom of the groove and on the other hand, a fixation. By using the bottom as a reference surface, it is possible to compensate for tolerances on the adjustment mechanism and to be able to set a predetermined distance to the bottom of the groove via the actuator, regardless of whether the guide rail is fixed within the tolerance higher or lower to the furniture body , This allows a lateral support of the guide element is ensured by the walls of the groove safely by a maximum coverage of the guide element can be achieved in the walls of the groove. In this case, the walls of the groove can be made shorter, since defined installation conditions can be obtained more easily.

Preferably, upon actuation of the actuator from the adjustment position to the fixed position, simultaneous movement of the guide member away from the bottom of the groove occurs. As a result, the movement of the actuating device can be used to effect, on the one hand, a fixation and, on the other hand, an adjustment of the guide element.

For ease of assembly, the guide element can be biased towards the bottom of the groove via a force accumulator, preferably a spring. During assembly, the guide element can then be supported on the bottom of the groove, so that a defined distance between the bottom of the groove and the guide element is generated when adjusting the actuator from the adjustment position to the fixed position, for example in a range between 0 , 5 mm to 4 mm, in particular 1 mm to 3 mm. For a simple operation, the actuator can a

pivotable actuating portion include, wherein the actuating device is rotatable from the adjustment position to the fixed position. The actuation of the actuator can be performed manually with the sliding element mounted or automatically moving the sliding element by a fixed to the furniture body activator to ensure that the guide element is after triggering the actuator when moving the sliding element in the fixed position.

For an exact alignment of the guide element this can be continuously adjustable relative to the holder. The actuating device may comprise a sleeve, is formed on or in the at least one drain contour with a slope. The drain contour is arranged like a helix about the axis of rotation of the sleeve. In this case, the at least one drain contour is preferably arranged on the front side of the sleeve. By a path movement of a point on the at least one drain contour about the axis of rotation of the sleeve, the guide element is moved by a distance dependent on the slope distance in the direction of the axis of rotation of the sleeve. Ultimately, thus causing a rotation of the sleeve displacement of the guide element away from the bottom of the groove. Furthermore, the actuating device preferably has a smooth-walled adjustment section, which in a displacement position is opposite to a profiled section on the holder, and in the fixed position, a latching section on the actuating device engages with the profiled section, such that a displacement of the guide section is effected in the adjustment position can be what is prevented in the fixed position on the locking portion.

It is also conceivable to design the drainage contour as a single or multi-start thread path arranged circumferentially on the sleeve and provided with a slope. Here, either this thread itself by self-locking or other suitable, not described here means ensure that an unintentional adjustment from the adjustment takes place in the fixed position. For a compact design of the holder may be formed substantially plate-shaped in order to mount this on a rear wall of a sliding element can. Further, guides may be provided on the holder to guide the guide member linearly on the holder. The guide element may be U-shaped, wherein an insertable into the groove Guide section on a first leg and a guided on the holder portion are provided on a second leg. By different spacing of the two legs from each other, the guide element can optionally be used for front or rear sliding elements.

According to the invention, the guide device is used for furniture, in particular for sliding elements. But it is also possible to use the guide device in Faltschiebeelementen, partitions or other linearly displaceable components.

In the method according to the invention for mounting a sliding element, first a guide element is positioned adjacent to a groove of a guide rail, in order then to move the guide element against the force of an energy accumulator, preferably a spring, and to thread a part of the guide element into the groove Guide element comes to a bottom of the groove to the plant. Subsequently, the guide member is fixed in the groove via an actuator, wherein by moving the actuator, the guide member is removed from the bottom of the groove. As a result, the distance between the bottom of the groove and the guide element can be precisely adjusted, so that the overlap in the groove can be maximized and at the same time a simple compensation of tolerances is possible.

For ease of assembly, the actuating device can be pivoted for fixing the guide element, so that when pivoting the guide element is lifted from the bottom of the groove.

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

A piece of furniture 1 comprises a furniture body 2, on which a rear sliding element 3 and a front sliding element 4 are movably mounted. It is also possible to provide more than two sliding elements 3 and 4 on a furniture body 2. The sliding elements 3 and 4 are held suspended on a bearing rail on the top floor, wherein at a bottom of the furniture body 2, a guide rail 6 is provided to the front sliding element. 4 to guide over first guide means 7 by means of guide elements 8 '. The rear sliding element 3 is guided via second guide means 5 by means of guide elements 9 which function in the same way as the guide means 7.

In Figure 2, the guide means 5 and 7 in a partial section of the furniture 1 according to the line I I-I I shown. A guide rail 6 is fixed to the furniture body 2 in the region of the bottom and has two downwardly open grooves 60 and 61. In the closer to the furniture body 2 groove 60, a guide portion 80 of a guide member 8 is arranged, which is U-shaped in cross section and is fixed on the side facing away from the guide portion 80 on a holder 10 at the back of the sliding element 4. In a similar manner, in the guide element 9, a guide section 90 is inserted into the groove 61, wherein the guide element 9, which is U-shaped in cross-section, is fixed to a holder 10 at the back of the sliding element 3 with a second leg.

In Figure 2 it is shown that the guide portions 80 and 90 are inserted into the grooves 60 and 61 of the guide rail 6, but no positioning and fixing of the guide elements 8 and 9 has been made. For this purpose, an actuating device 20 is provided on each guide element 8 and 9, which is movable from an adjustment position into a fixing position.

In Figure 3, the actuators 20 have been moved to the guide elements 8 and 9 in the fixing position. By adjusting the actuator 20, the guide portions 80 and 90 have been moved by a predetermined amount each from a bottom 63 of the grooves 60 and 61, so that a small gap 62 is formed in the grooves 60 and 61 in the vertical direction, for example, in one area from 0.5 mm to 4 mm, to avoid grinding noises when moving the sliding element 3 and 4 safely.

In Figure 4, the guide device 5 is shown in detail. The guide device 5 comprises a plate-shaped holder 10 which can be mounted on a sliding element 3 and has openings 11 which can be passed through for the purpose of mounting fastening screws. On the holder 10, two bar-shaped guides 1 2 project to guide the guide element 9 linearly in a vertical direction on the holder 10. Further, a protruding support member 1 3 is formed on the holder 1 0, on which one end of a spring 30 formed as an energy accumulator is supported. In a middle area of the Holder 1 0 is also a profiled portion 14 formed with teeth, by means of which the guide element 9 can be fixed in the fixed position.

The guide element 9 is U-shaped in cross-section and comprises a guide portion 90 which can be inserted into the groove 61 of the guide rail 6. The guide portion 90 is connected via a transverse web 91 with a leg 92 which is linearly guided on the holder 1 0. On the leg 92, two guide rails 95 are formed in the lower region, which can be inserted into corresponding strip-shaped receptacles on the guides 1 2. On the leg 92, a recess 94 is further provided, in which a spring 30 is inserted. The spring 30 is supported at the upper end to a stop 97 of the recess 94 and at a lower end to the support member 1 3 of the holder 1 0, so that the guide member 9 is biased on the holder 1 0 upwards. Furthermore, a further recess 93 is formed on the leg 92, on which helical, vertically extending counter contours 82 are formed with a .Steigung respectively at the upper edge and the lower edge, which are closer in the figure 8 can be seen.

The guide device 5 further comprises an actuating device 20 in order to be able to move the guide element 9 from an adjustment position into a fixed position. The actuating device 20 comprises an actuating portion 21 which is rotatably mounted, and a rod 22 which is non-rotatably connected to a sleeve 23 of the actuator 20. The sleeve 23 is in turn rotatably held or mounted in the recess 93 of the holder 1 0.

The sleeve 23 is shown in detail in FIGS. 5A and 5B. In the sleeve 23, a receptacle 24 is formed, which is rotatably engaged with the rod 22, for which purpose the rod 22 and the receptacle 24 with the same

Cross-sectional contour, for example square, are formed. The sleeve 23 comprises on the outer circumference a smooth-walled adjustment section 26 and a latching section 25. In an adjustment of the smooth-walled adjustment section 26 relative to the profiled section 14 on the holder 1 0 is arranged, while in the fixed position of the latching portion 25 in engagement with the profiled section 14th is to prevent a vertical movement of the guide member 9 relative to the holder 1 0. On the front side, respective rising discharge contours 27a and 27b are arranged on the sleeve 23, which are helical or spiral-shaped around the axis of rotation of the sleeve 23. In FIGS. 6A to 6F, the guide device 5 is shown in an adjustment position. In the adjustment position, the spring 30 pushes the guide member 9 upwards until the guide portion 90 abuts against the bottom of the groove 61. Since the smooth-walled adjustment section 26 of the sleeve 23 is arranged opposite the profiled section 14 on the holder 10, the guide element 9 can be moved freely in the vertical direction. The actuating device 20 is in an adjustment position, wherein the actuating portion 21 is held on latching elements 96 which are integrally formed on the underside of the transverse web 91.

If now the guide member 5 are moved to a fixed position, the actuating portion 21 is pivoted, as shown by the comparison of Figures 6F and 7D. In FIGS. 7A to 7E, the guide device 5 is shown in the fixed position.

By pivoting the actuator 20 on the actuating portion 21, the sleeve 23 of the actuator 20 is rotated, whereby the smooth-walled adjustment portion 26 is moved along the profiled portion 14, so that the profiling of the latching portion 25 engage the profiled portion 14. By the rotational movement of the sleeve 23 in addition to a fixation and an adjustment of the guide member 9 is effected relative to the holder 1 0, since by the slope of the helical manner about the axis of rotation of the sleeve 23 arranged drain contours 27a and 27b when rolling on the mating contours 82 of the legs 92nd and thus also the guide element 9 is moved vertically downwards. This results in a height adjustment of the guide element 9 away from the bottom 63 of the groove 61 by turning the actuator 20. In this case, the guide element 9 is moved by a distance dependent on the slope distance in the direction of the axis of rotation of the sleeve 23 by the path movement of a point on the drain contour 27a and 27b about the axis of rotation of the sleeve 23. The adjustment in the vertical direction, ie in the direction of the axis of rotation of the sleeve 23, may be slight to ensure that an end face of the guide portion 90 does not drag at the bottom of the groove 61. When the latching portion 25 is engaged with the profiled portion 14, the guide member 9 can not be displaced along the holder 10, and thus the position of the guide member 9 is fixed.

In Figure 8, the guide means 7 for the front sliding element 4 is shown in detail. The guide device 7 is like the guide device. 5 constructed, only with the difference that the guide element 8 is designed differently, since the distance between a leg 92 and the guide portion 80 is formed larger than in the guide means 5. The guide portion 80 is connected via a transverse web 81 with the leg 92 connected , In the recess 93 in the upper region and also in the lower region (not shown) helical, extending in the vertical direction counter contours 82 are formed, which cooperate as already described, with the configured on the sleeve 23 drain contours. Otherwise, the guide device 7 corresponds to the guide device 5.

In FIGS. 9A to 9D, the guide device 7 is shown in an adjustment position. In this position, the guide portion 80 can be moved relative to the holder 1 0 in the vertical direction, as already explained above. In order to move the guide device 8 from the adjustment position to the fixed position, an actuating portion 21 of the actuating device 20 is pivoted, whereby the latching portion 25 engages the profiled portion 14, wherein at the same time the guide portion 80 due to the rotational movement of the sleeve 23 arranged drain contours 27a and 27b is slightly moved relative to the holder 1 0 down, for example, between 0.5 mm and 4 mm.

In Figures 1 1 A to 1 1 D, the assembly of the guide means 5 for the rear sliding element 3 is shown. The sliding element 3 is first hung on a bearing rail on the upper floor of the furniture body 2, and the guide element 9 is positioned adjacent to the grooves 60 and 61 of the guide rail 6, as shown in Figure 11A. The sliding element 3 can be placed in this position on a floor, without the guide element 9 is damaged, it being possible to arrange the guide member 9 and the holder 1 0 above a lower end edge of the sliding element 3, so that on the sliding element 3 no are provided downwardly projecting parts.

For mounting the sliding element 3, the guide element 9 is moved downward against the force of the spring 30, as shown in FIG. 11B. As a result, the guide portion 90 is below the downwardly open groove 61 of the guide rail 6, and the guide portion 90 can now be threaded into the groove 61, as shown in Figure 11C. The guide element 9 can now be released, so that an end face of the guide portion 90 abuts against the bottom 63 of the groove 61. Here, the Bo- the 63 as a reference surface for the following described removal of the guide element. 9

After the guide element 9 has been aligned according to Figure 1 1 C, the guide element 9 is now moved from the adjustment position into the fixed position, for which purpose the actuator 20 is pivoted about the actuating portion 21. By pivoting the actuating device 20, the guide element 9 is moved slightly downward by a predetermined amount, as dictated by the pitch of the drain contours 27a and 27b when draining within the recess 93. When a certain rotation of the sleeve 23 has taken place, the profiled portion 14 arranged on the sleeve 23 meshes with the latching portion 25 on the holder 10. As a result, the sleeve 23 and thus also the guide element 9 are locked in their entirety on the holder 10 and 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 bottom of the groove 61.

FIGS. 1 2A and 1 2B show a modified exemplary embodiment of a guide device in which a modified guide element 9 'is used, which is otherwise formed as in FIG. 4, with the difference that a recess 98 is formed in the region of the guide section 90 is, in which a guide roller 99 is rotatably mounted. The guide roller 99 is cylindrical and projects laterally beyond the guide portion 90. The guide roller 99 is rotatably mounted around a vertical axis and prevents the guide section 90 from coming into contact with the side walls of the groove 61. As a result, lower friction forces are generated during the process of the sliding element 3.

In FIG. 1C, the guide element 9 'of FIGS. 1 2A and 12B has been modified, since two guide rollers 99 instead of a guide roller 99 are provided in the recess 98 on the guide section 90. The two guide rollers 99 both have a vertical axis of rotation and reduce the friction during the movement of the sliding element 3. The guide rollers 99 can be aligned in a plane parallel to the longitudinal direction of the guide rail 6 or offset to ensure optimized guidance.

A modified embodiment is shown in FIGS. 1A and 1B, in which the actuating device 20 with the actuating section 21 is pivoted not manually but via an activator. This is adjacent to the guide rail 6, an activator 40 is mounted, which may be formed, for example, as a cuboidal component, which may be bevelled at one, the operating portion 21 side facing. When moving the sliding element 3, the actuating section 21 now encounters these

beveled side, whereby the actuating portion 21 is pivoted from the adjustment position (Figures 13A and 13B) in the fixed position (Figure 13C). By installing a preassembled activator 40 thus incorrect assembly can be safely avoided. This is particularly advantageous if only one guide device 5 or 5 'or 7 or 7' is arranged on a sliding element 3 and / or 4.

FIG. 14 shows an exemplary embodiment in which a guide rail 6 'is not arranged on the bottom of a furniture carcass 2 but on an upper floor. A groove on the guide rail 6 'is formed open at the bottom and a guide portion 70 of a guide element engages in the groove. The guide section 70 is held adjustably on a guide device 5 ', the guide device 5' having an actuating device 20 'to be able to adjust the guide section 70 relative to the groove of the guide rail 6', as already described in the preceding exemplary embodiments has been. However, the guide part with the guide portion 70 is not U-shaped but elongated or web-shaped.

The sliding door 3 is supported in the embodiment of Figure 14 on at least one bottom-side running part, which is movable via a roller 71 in a running rail 72.

It is also possible to provide synchronization between a plurality of guide devices 5 and 7 on a sliding element 3 or 4, so that by actuating an actuating device 20, both guide elements 8, 9 or 9 'are simultaneously moved from the adjustment position into the fixed position. Such synchronization can be done for example via a cable or a connecting rod. LIST OF REFERENCE NUMBERS
