Description

The present invention relates to a guiding device for parts that can be moved along a guiding device, in particular for sliding door fittings, which comprises a first rail-shaped adapter and at least one additional second rail-shaped adapter, which can be installed in an extension of the first rail-shaped adapter, and to the installation method of the guide device.

DE 7528036 discloses sliding door hardware in which several rail profiles are connected to each other via a butt connector. Thus, rail profiles can be transported with a shorter length for assembly by means of butt connectors at the furniture assembly site. The division of the guide profiles into separate short sections has proven itself, but the use of a butt connector requires a certain amount of additional space. There is also a disadvantage in that the butt connector and the guide profile must be manufactured with a high degree of accuracy in order to provide an accurate, flat guide. Minor angle or step changes are noticeable to the user when moving the carriage along the junction.

Thus, it is an object of the present invention to provide a guiding device for parts adapted to be moved along the guiding device, which can be transported in a compact manner and allows alignment of deviations from tolerance during installation.

This problem is solved by means of a guiding device with the characteristics of paragraph 1 of the claims.

According to the invention, at least one continuous guide element made of flexible material is attached to the first adapter and to the second adapter. As a result, said at least one continuous guide element can be bent for transportation so as to reduce the necessary total space for the guide element, while the continuous guide element has the advantage after installation that there are no steps or bends at the connecting point. The specified at least one continuous guide element is made of flexible material, so that certain tolerances between the adapters in the form of straps can be offset by a slightly convex, continuous shape of the guide element. Such a slightly convex shape is almost not noticeable to the user when moving the part along the guide device, since the step or angle is distributed over some bending area, while the changes in the angle or steps are only slight, for example, less than 1 mm or less than 2 °. The material of the continuous guide element is selected in such a way that, after installation, the guide element has sufficient rigidity in case of load to reliably guide the moving parts. In addition, the bending radii of the continuous guide element during transportation are selected so that after installation there is no plastic deformation.

The first and / or second adapter is preferably made of a geometrically stable material, in particular plastic or metal. Thus, said at least one continuous guide element can be firmly attached to the adapters.

For a particularly compact manufacture of a flexible guide element, it can be wound on a roll and then transported in roll form. The flexible guide member can be unwound from the roll to install the guide device and then attached to the adapters. The flexible guide element can be made in the form of a plate or element of the core profile and is preferably fixed on the first and / or second adapter. Several continuous guide elements may be attached to the first and / or second adapter.

To reduce the accuracy requirements of the adapters, they can be attached with a clearance to the furniture body. The gap between the two adapters can be less than 1 mm, in particular from 5 to 50 mm, so that flexible adjustment along the length of the guide device can be carried out by installing adapters. The choice of clearance depends on the geometry of the furniture and sliding doors or the weight of the sliding door.

According to a preferred embodiment, the continuous guide elements are made in the form of plates, between which a groove is formed to accommodate the sliding element. Several plates can be attached parallel to each other on adapters.

Said at least one guide element preferably has a sliding coating, which is particularly preferred in the sliding guide.

In an additional embodiment, the guide element is made in the form of a rod profile placed in a bath-shaped socket of the adapter and fixed there. The rod profile can form a guide, in particular for rollers.

To prevent the longitudinal movement of the guide elements in the adapter sockets, you can use contact surfaces with locking elements located on the longitudinal side, for example, in the form of engaging elements.

In addition, the locking elements can be arranged in the cross section of the contact surfaces to enable the rotation of the guide element to facilitate installation and disassembly.

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

In the method according to the invention for mounting the guide device, the first rail-shaped adapter is attached to the furniture body and then at least one second adapter in the form of a strap is attached to the furniture body in extension of the first adapter. A flexible continuous guide element is then attached to the first and second adapter to provide a continuous guide device. In an alternative method, the guide element is first attached to the first adapter in the form of a strip and then to the second adapter in the form of a strip in extension of the first adapter. The finished guide device is then attached to the furniture body. The guide element can be cut to the required length before or after the adapters are installed, so that the length can be adjusted to allow the use of a guide device for furniture bodies with different widths.

The invention is explained in more detail below with reference to several options for its implementation, shown in the accompanying drawings, in which:

Furniture item 1 comprises a furniture case 2 on which a rear sliding door 3 and a front sliding door 4 are mounted with a possibility of displacement. A first guide device 5 in the form of a sliding guide is mounted on the base of the furniture body 2, while the second guide device 6 is in the form of a roller hardware guide a sliding door is mounted on the top panel. Instead of two sliding doors 3, 4, three or more doors can be mounted with the possibility of displacement on the furniture body 2. In addition, sliding doors can also be formed with a flush arrangement instead of an offset arrangement.

In FIG. 2, a guide device 5 for guiding the rear sliding door 3 and the front sliding door 4 is shown in detail. Each sliding door 3, 4 is attached in the lower region to at least one U-shaped holder 13 attached by means of the first shelf 15 to the inside of the sliding door 3 or 4. Opposite shelf 14 comprises a sliding member 12 longitudinally guided by the guiding device 5. For this purpose, the sliding member 12 is engaged between two plates 11, which form grooves for t second, to minimize the movement of the sliding member 12 is perpendicular to the longitudinal direction. The plates 11 are attached to the adapter 10 in the form of a strap screwed to the base of the furniture body 2, in which corresponding holes 16 are cut out on the adapter 10 for this purpose. Obviously, it is also possible to attach the adapter 10 to the base of the furniture body using other types of connection, for example, by snap connection or gluing.

In FIG. 3 shows a first embodiment of a guide device in which a first adapter 10 and a second adapter 10 'are used. The lengths of the adapters 10 and 10 'are selected regardless of the width of the furniture body and can range from 0.5 m to 1 m, so transportation is easily possible. To provide a guide device 5 of greater length, the adapters 10 and 10 'are mounted one after the other in the longitudinal direction, and between the adapters 10 and 10' a gap 23 greater than 1 mm can be provided, for example, in particular from 5 mm to 50 mm. Adapters 10 and 10 'are made of geometrically stable material, such as plastic or metal, in particular aluminum. The plates 11, on the other hand, are made of a flexible material of sufficient strength, such as plastic, a thin metal strip or other material that is flexible and can provide certain guiding functions for the sliding element 12.

In FIG. 4 shows a modified guide device 5 in which three adapters 10, 10 'and 10' 'are used, which can be formed in the same way and each of which can be mounted one after the other in the longitudinal direction on the furniture body 2. The distance between the adapters 10, 10 'and 10' 'is made large in this case, so that there are gaps 23 between the adapters 10, 10' and 10 '' that can be closed by means of the plates 11. Since the plates 11 are made of flexible material, no steps or bends appear even when the adapters 10, 10 'and 10' 'are installed with a slight offset on the furniture body 2. The plates 11 are thus slightly curved, however this is barely noticeable during the displacement of the sliding doors 3, 4.

In FIG. 5 shows a guide device 5 during installation. The adapter 10, made of a geometrically stable material, is essentially formed in the form of a strip and includes a wall-shaped holder 17 in which there are holes 16 for attaching to the furniture case 2. The adapter 10 further comprises a mounting section 18, on which several grooves 19 are formed between the protruding walls 22. The grooves 19 have an expanded section 20 at the base of the groove to allow locking of the plates 11 with a geometric and / or power short circuit. For this purpose, the walls 22 are made slightly flexible, and the plates 11 have an enlarged head section 21 on one side, but otherwise are made with a substantially rectangular cross section.

In FIG. 6 plates 11 were mounted on the adapter 10 so that the ends with the enlarged head section 21 are inserted into the grooves 19 for subsequent fixation in areas with extended sections 20. The plates 11 are fixed by the protruding walls 22 in the direction perpendicular to the longitudinal direction of the grooves 19. The protruding part of the plates 11 has a height H, which lies in the range from 5 mm to 30 mm, in particular, for example, from 10 to 15 mm. The width B between the plates 11 may lie in the range from 4 mm to 30 mm, in particular, for example, from 4 mm to 20 mm. The plates 11 may have a thickness of from 0.5 mm to 5 mm, in particular from 1 to 3 mm.

In FIG. 7A shows a plate 11 in section. The enlarged head section 21 protrudes circularly at the end section. In accordance with FIG. 7B alternatively, instead of the enlarged end section 21, one or more grooves 21 'can be used for fixing on the plate 11', into which the corresponding locking protrusions engage on the walls 22. It will be appreciated that other cross-sectional shapes on the head of the plate can be used for fixing on the adapters.

In FIG. 8A shows plate 11 in the transport position. The plate 11 is wound on a roll or arranged in a spiral manner, then it can be bent into a linear position for installation. Alternatively, in accordance with FIG. 8B, the plate 11 can be formed as a loop, with the minimum bending radius R of the plate 11 being greater than 10 cm, for example, greater than 20 cm. The bending radius R should preferably be chosen so small that the plate 11 does not undergo any permanent plastic deformation after installation.

In FIG. 9 shows a second guide device 6, which is mounted on the top panel of the furniture cabinet 2. The guiding device 6 comprises a first adapter 30 in the form of a strip and a second identical adapter 30 'in the form of a strip, both of which are made of a geometrically stable material, such as metal or reinforced plastic.

As shown in enlarged view in FIG. 10, a second adapter 30 ′ is located in an extension of the first adapter 30, with both adapters 30 and 30 ′ having a shelf 32 lying on the top panel of the furniture cabinet 2 and secured with fasteners, such as screws that engage with engagement through holes 31 Each adapter 30 and 30 'further comprises a vertical wall 33 and a horizontally aligned holder 34 on which there are bath-shaped slots for inserting at least one guide element 40 in the form of a strap. In the embodiment shown, two guide elements 40 in the form of a bar are used, and obviously, only one or more of two guide elements 40 can also be installed on the adapters 30 and 30 '.

A gap 35 is formed between the adapters 30 and 30 ', this gap being overlapped by the guide elements 40.

As shown in FIG. 11, the guide elements 40 are used as a guide for the roller 36 of the movable part of the sliding door hardware on which the sliding doors 3, 4 are suspended. The rollers 36 roll on the upper surface of the guide elements 40, while the lower sides of the guide elements 40 are held in the slots on the holder 34. Adapters 30, 30 'are preferably made of bent steel sheet, and they can also be made of steel profile or aluminum profile. The flexible guide elements 40 are made of another flexible material, preferably metal with sufficient strength, for example, metal wire, so as to be bent to transport and overlap the adapter portion between the two adapters 30 and 30 '.

In FIG. 12A shows a rod-shaped guide member that is wound into a roll, bundle or reel in order to reduce volume during transport. In FIG. 12B shows a guide element in a transport form arranged in a loop or wriggling manner for long lengths.
