Description

The present invention relates to a guide device for moving along the guide device parts, in particular for a sliding door fitting, according to the preamble of claim 1 and further a method for mounting a guide device.

The DE 75 28 036 discloses a sliding door fitting in which a plurality of guideway profiles are interconnected via a butt connector. As a result, the guideway profiles can be transported in a shorter length, to then be plugged together at the location of the furniture structure with the butt connectors. The division of the guideway profiles into individual shorter sections has proven itself, but the use of a butt connector requires a certain amount of additional space. In addition, there is the disadvantage that butt joints and guideway profiles must be manufactured with high accuracy in order to provide an exact flat guideway. Smaller angle changes or steps are perceived by the user as the carriage travels along the junction.

The GB 1 046 950 discloses a track rail having two interconnected rail pieces. In the area of the connection of the rail sections, reinforcing elements made of metal are welded to the rail sections.

It is therefore an object of the present invention to provide a guide device for along the guide device movable parts that can be transported in a compact form and allows tolerance compensation during assembly.

This object is achieved with a guide device having the features of claim 1.

According to the invention, at least one continuous guide element made of a bendable material is fixed to the first adapter and the second adapter. As a result, the at least one continuous guide element can be bent for transport in order to reduce the required installation space of the guide element, the continuous guide element having the advantage after assembly that no steps or kinks are present at a connection point. The at least one consistent Guide element is made of bendable material, so that certain tolerances between the strip-shaped adapters can be compensated by a slightly arcuate, steady course of the guide element. Such a slightly curved course is hardly perceived by the user when moving a part along the guide device, since a step or angle is distributed over a certain bending range and the angle changes or steps are only slight, for example less than 1 mm or less than 2 °. The material of the continuous guide element is chosen so that the guide element has sufficient rigidity after mounting in the load case to guide moving parts safely. Furthermore, the bending radii of the continuous guide element are selected during transport in such a way that no plastic deformation occurs after assembly.

Preferably, the first and / or second adapter made of a dimensionally stable material, in particular made of plastic or metal. As a result, the at least one continuous guide element can be stably fixed to the adapters.

For a particularly compact production of the bendable guide element this can be wound on a roll and then transported in the roll form. For the assembly of the guide device then the bendable guide element can be unwound from the roll and fixed to the adapters. The bendable guide element is designed as a lamella or rod profile and is preferably latched to the first and / or second adapter. In this case, several continuous guide elements can be fixed to the first and / or second adapter.

To reduce the accuracy requirements of the adapters, they can be defined with a gap on a carcass. The gap between two adapters can be at least 1 mm, in particular 5 to 50 mm, so that a flexible length adjustment of the guide device can be made by mounting the adapter. The choice of the gap is dependent on the body geometry and the sliding door geometry or the sliding door weight.

According to a preferred embodiment, the continuous guide elements are formed as lamellae, between which a groove for receiving a sliding element is formed. Several lamellae can be fixed parallel to each other on the adapters.

Preferably, the at least one guide element is provided with a lubricious coating, which is particularly advantageous in a sliding guide.

In a further embodiment, the guide element is designed as a rod profile, which is inserted into a trough-shaped receptacle of the adapter and fixed there. The bar profile can then form a career especially for rollers.

In order to prevent a longitudinal movement of the guide element in the receptacles of the adapter, it is conceivable to equip the contact surfaces with longitudinally arranged blocking elements, for example in the form of toothed elements.

Furthermore, it is possible to arrange blocking elements in the cross-section of the contact surfaces in order to enable a pivotability of the guide element for easier assembly and disassembly.

The guide device according to the invention is used in particular as a sliding guide or roller guide of a sliding door fitting for furniture. Other uses are possible.

The object is further achieved in each case with a method for mounting a guide device with the features of claim 11 or 12.

In a method according to the invention for mounting a guide device, first a first strip-shaped adapter is fixed to a body, and then at least one second strip-shaped adapter is fixed in extension of the first adapter to the body. Subsequently, at least one bendable continuous guide member is fixed to the first and second adapters to provide a continuous guide device. In an alternative method, the guide element is first fixed to the first strip-shaped adapter and then to the second strip-shaped adapter in extension of the first adapter. Finally, the completed guide device is then fixed to the body.

The guide element can be cut to the desired length before or after assembly of the adapter, so that a length adjustment can be made to make the guide device for different width furniture carcasses used.

A piece of furniture 1 comprises a body 2, on which a rear sliding door 3 and a front sliding door 4 are displaceably mounted. For this purpose, at the bottom of the body 2, a first guide device 5 in the form of a sliding guide and on Upper floor mounted a second guide device 6 in the form of a roller guide of a sliding door fitting. Instead of two sliding doors 3 and 4, three or more doors can be movably mounted on a carcass 2. In addition, the sliding doors can be designed instead of staggered arrangement in a flush arrangement.

In FIG. 2 the guide device 5 for guiding the rear sliding door 3 and the front sliding door 4 is shown in detail. Each sliding door 3 and 4 is connected at the bottom with at least one U-shaped holder 13 which is fixed with a first leg 15 on the inside of a sliding door 3 or 4. The opposite leg 14 comprises a sliding element 12, which is guided on the guide device 5 in a longitudinal direction. For this purpose, the sliding member 12 engages between two fins 11, which form a groove between them in order to minimize movement of the sliding member 12 perpendicular to the longitudinal direction. The fins 11 are fixed to a strip-shaped adapter 10 which is screwed to the bottom of the body 2, wherein corresponding openings 16 are recessed on the adapter 10. Of course, it is also possible to fix the adapter 10 with other types of connection, for example clipping or gluing, to the bottom of the body.

In FIG. 3 a first embodiment of the guide device 5 is shown, in which a first adapter 10 and a second adapter 10 'are provided. The length of the adapter 10 and 10 'is selected depending on the body width, for example, can be between 0.5 m and 1 m, so that a transport is easily possible. In order to provide the guide device 5 in a greater length, the adapters 10 and 10 'are mounted one behind the other in the longitudinal direction, wherein a gap 23 between the adapters 10 and 10' may be provided, for example, greater than 1 mm, in particular between 5 mm 50 mm. The adapters 10 and 10 'consist of a dimensionally stable material, for example plastic or metal, in particular aluminum. The lamellae 11, however, consist of a bendable material of sufficient strength, such as plastic, a thin metal strip or other material, which is bendable, but can take over a certain leadership function for the slider 12.

In FIG. 4 a modified guide device 5 is shown, in which three adapters 10, 10 'and 10 "are provided, which can be made identical in construction and can be mounted one behind the other in the longitudinal direction on the body 2. The distance between the adapters 10, 10' and 10 " is here formed larger, so that gaps 23 are provided between the adapters 10, 10 'and 10 "which are bridged by the slats 11. Since the slats 11 consist of bendable material, there are no steps or kinks, even if the adapters 10, 10 ', 10 "with a slight offset to the body 2 are mounted. As a result, the slats 11 are bent slightly, but this is barely noticeable when moving the sliding doors 3 and 4.

In FIG. 5 the guide device 5 is shown during assembly. The adapter 10 of dimensionally stable material is substantially strip-shaped and has a web-shaped holder 17, in which the openings 16 are provided for attachment to the body 2. Furthermore, the adapter 10 comprises a fastening portion 18, on which a plurality of grooves 19 are formed between protruding webs 22. The grooves 19 have on the groove bottom on a widened portion 20 in order to lock the slats 11 positively and / or non-positively. For this purpose, the webs 22 are slightly bendable, and the slats 11 have on one side a thickened head portion 21, but are otherwise formed substantially rectangular in cross-section.

In FIG. 6 For example, the fins 11 were mounted on the adapter 10 by inserting the ends with the thickened head portion 21 into the grooves 19, and then locking them in the areas with the widened portions 20. The fins 11 are fixed by the protruding webs 22 in a direction perpendicular to the longitudinal direction of the grooves 19. The protruding part of the fins 11 has a height H, which is for example in a range between 5 mm to 30 mm, in particular 10 mm to 15 mm. The width B between the slats 11 may for example be in a range between 4 mm and 30 mm, in particular 4 mm to 20 mm. The fins 11 may have a thickness between 0.5 mm and 5 mm, in particular 1 to 3 mm.

In FIG. 7A a lamella 11 is shown in cross-section. The thickened head portion 21 protrudes circularly at an end portion. Alternatively, it is according to FIG. 7B possible, instead of a thickened head portion 21 for locking one or more grooves 21 'on a blade 11' to provide, engage in the corresponding latching projections on the webs 22. Of course, other cross-sectional shapes on a head section of the lamella for locking to the adapters are conceivable.

In Figure 8A a blade 11 is shown in a transport position. The blade 11 is wound on a roll or helically arranged and can then be bent for mounting in a linear position. Alternatively, it is according to FIG. 8B possible to form the lamella 11 loop-shaped, wherein the minimum bending radius R of the lamella 11 may be greater than 10 cm, for example greater than 20 cm. Preferably, the bending radius R should only be chosen so small that after assembly, the blade 11 undergoes no permanent plastic deformation.

In FIG. 9 a second guide device 6 is shown, which is mounted on the top floor of the body 2. The guide device 6 comprises a first strip-shaped adapter 30 and a second identical strip-shaped adapter 30 ', which are both made of a dimensionally stable material, such as metal or reinforced plastic.

As in the enlarged view of FIG. 10 is shown, the second adapter 30 'is arranged in extension of the first adapter 30, and both adapters 30 and 30' have a leg 32 which rests on the top bottom of the body 2 and fasteners, such as screws, is fixed, the openings 31 to attack. Each adapter 30 and 30 'further has a vertical web 33 and a horizontally oriented holder 34, on which trough-shaped receptacles for inserting at least one rod-shaped guide member 40 are provided. In the embodiment shown, two rod-shaped guide elements 40 are provided, of course, only one or more than two guide elements 40 can be held on the adapters 30 and 30 '.

Between the adapters 30 and 30 ', a gap 35 is formed, which is bridged by the guide elements 40.

As in FIG. 11 is shown, the guide elements 40 serve as a track for a roller 36 of a running part of a sliding door fitting, on which the sliding doors 3 and 4 are suspended. The rollers 36 roll on the upper surface of the guide elements 40, while the underside of the guide elements 40 are held in the receptacles on the holder 34. The adapters 30 and 30 'are preferably made of a bent sheet steel, but may also be made of a steel profile or aluminum profile. The bendable guide elements 40 are another flexible material, preferably a metal with sufficient strength, for example a Metal wire, made to be bent for transport, and to bridge the transition between two adapters 30 and 30 '.

In FIG. 12A a rod-shaped guide element 40 is wound into a roll, a collar or a worm to reduce the volume during transport. In FIG. 12B the guide element is in the form of a loop in the form of a channel or, in the case of larger lengths, in a meandering arrangement.
