Description

The present invention relates to a guide device for a sliding door according to the preamble of claim 1.

The DE 10 2010 037 940 discloses a roller guide for a sliding door, in which a guide roller is rotatably mounted on a lever system, wherein the lever system comprises a guide lever and a support lever, which are hinged together. As a result, the guide roller is guided spring-loaded along a rail, so that tolerances can be compensated and easy installation is possible. However, the lever mechanism requires a large number of components.

The DE 410 911 discloses a sliding door fitting with a running ball, which can be secured via a resilient wire bracket in an end position.

It is therefore an object of the present invention to provide a guide device for a sliding door, which is easy to assemble and comprises only a few components.

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

According to the invention, the guide device comprises a guide element, a holder and a connecting element for connecting the holder to the guide element, wherein the connecting element comprises a bent wire. As a result, the guide device can be constructed with only a few components. In addition, a flexible adaptation to other installation widths of the guide device is possible by the use of a bendable bent wire. Thus, variable length differences can be realized. Furthermore, a simplified door assembly is made possible by pivoting the guide means by means of the bent wire.

In addition, the connecting element between the guide element and the holder at least two spaced sections of bent wire. Thereby, the two spaced portions can be aligned differently, for example, to adjust the distance between the holder and the guide member. Further, the connecting member is prevented from rotating about an axis of the wire. The connecting element can thereby adjust by elastic bending of the wire, the distance between the guide element and the holder, wherein the bending is largely in the elastic region. A bending in the plastic area should be avoided as much as possible. For flexible adaptation of the distance between the holder and the guide element, the bendable wire can have two end sections, which can be fixed in different positions on the holder or the guide element. For fixing the end portions of the bendable wire insertion openings or receptacles may be provided, so that a simple installation is ensured.

Preferably, the two spaced sections of bendable wire intersect each other so that the crossed sections can be oriented at different angles to make a change in length of the connecting element.

The bent wire is according to the invention of a side view seen in the longitudinal direction of the rail U-shaped, wherein on a first leg of the holder and on a second leg, the guide element are arranged or formed.

The guide member is mounted on a bracket of the bent wire or formed integrally with the bracket. Further, the guide member may be pivotally supported on the bracket, which facilitates the mounting of a front side of a furniture body.

For a simple assembly of the connecting element, this can be rotatably mounted on a horizontal axis on the holder. Furthermore, the connecting element can be locked in a mounting position on the holder.

It is also conceivable to assemble the connecting element from a plurality of bendable wires, which can be connected to one another either by additional components or by means of common production methods.

Preferably, the material of the bendable wire made of metal, but also plastic can be used for this purpose.

The guide device according to the invention is used in particular for furniture with a sliding door, but other purposes of the guide device are possible.

In a method for mounting a sliding door on a cabinet furniture, a holder is first fixed to a sliding door, wherein on the holder a guide element is provided, which is movable along a lower rail. Then, the sliding door is hung on an upper rail and insert the guide member relative to the holder around the guide member in a groove on the lower rail. As a result, the installation of the sliding door can be simplified. In addition, if a flexible wire is used as the connecting element, damage when settling on the floor can be avoided.

A cupboard 1 comprises a furniture body 2, on which a first sliding door 4 and a second sliding door 3 are movably mounted. For this purpose, an upper rail 5 is mounted on the upper floor and a lower rail 6 of a guide device according to the invention on the furniture body 2.

As in FIG. 2 is shown, the lower rail 6 has two downwardly open grooves 7 and 8, wherein in the groove 7 engages a guide member which is connected to the second sliding door 3. For this purpose, a holder 10 is mounted on the sliding door 3, which is connected via a connecting element 20 with the guide element.

In the FIGS. 3A and 3B the holder 10 and the connecting element 20 are shown in detail. The holder 10 is formed as a plate-shaped member, on which two openings 11 are provided for inserting screws for fixing to the sliding door 3. Further, the holder 10 on the bottom webs 12, on each of which a receptacle 13 for inserting an end portion 21 of the connecting element 20 is provided. In each case receptacles 13 are formed on both sides of the holder 10.

The connecting element 20 is formed from a bendable wire, which is made for example of metal, in particular stainless steel. The connecting element 20 comprises end portions 21 which can be inserted into the receptacles 13 on the holder 10 and secured there. Further, a portion 24 of the wire, which extends at the front of the holder 10, held in a locking receptacle 14, so that the connecting element 20 can be latched in a predetermined position on the holder 10. The connecting element 20 further comprises two spaced portions 22 extending substantially horizontally from the holder 10 to a guide member 23, which in this embodiment is integrally formed of the bendable wire extending substantially vertically upwardly into the groove 7 of the rail 6 extends. As in FIG. 3B is shown, the connecting element 20 has characterized seen a substantially U-shaped contour in the side view in the longitudinal direction of the rail 6. On one leg of the U-shaped contour of the holder 10 is provided, while on the opposite side, the guide member 23 is formed integrally with the wire. For an assembly of the connecting element 20, this can be inserted from below into the holder 10, if this is fixed to a rear side of the sliding door 3. Likewise, it is also possible to insert the connecting element 20 into the holder 10, before a fixing of the holder 10 to the sliding door 3 takes place.

In FIG. 4 a modified embodiment of a connecting element 20 'is shown in which, unlike that in the FIGS. 3A and 3B shown embodiment, the sections 22 'between the holder 10 and the guide member 23 intersect each other. Incidentally, the connecting member 20 'and the holder 10 are formed as in the previous embodiment.

In the FIGS. 5A and 5B the assembly of the connecting element 20 is shown on the sliding door 3. First, the end portions 21 are inserted into the receptacles 13, and then the connecting member 20 is pivoted about a horizontal axis formed by the end portions 21. Then the portion 24 engages the locking receptacle 14 on the holder 10, as shown in FIG FIG. 5B is shown. The two sections 22 are thereby aligned substantially horizontally and the bow-shaped guide member 23 is inserted substantially vertically in the downwardly open groove 7 and thus can prevent a horizontal movement of the sliding door 3 perpendicular to the longitudinal direction of the rail 6.

If the sliding door 3 is set down on the floor during assembly, the connecting element 20 can not damage the floor, since the connecting element 20 can be swiveled further upwards as required, as shown in FIG FIG. 5C is shown. Then the bendable wire is moved out of the locking receptacle 14 and pivoted upwards. As a result, plastic deformation of the connecting element 20 and damage to the floor is reliably avoided, which is the case with guide elements according to the state of Technique, which are made of an angular metal sheet, is not possible.

In FIG. 6 a modified embodiment of a guide device is shown in which a modified holder 30 and a modified connecting element 40 are provided. The holder 30 is designed as a plate-shaped component and comprises two openings 31 into which screws can be inserted for fixing to the sliding door 3. On the back of the holder 30, which faces the sliding door 3, insertion openings 32 and 33 are provided, can be inserted into the end portions 41 of the connecting element 40. The connecting element 40 is again made of a bent wire with a circular cross-section, wherein the connecting element comprises vertical end portions 41 and two horizontal, spaced-apart portions 42 which are interconnected via a bow-shaped guide member 43. The guide member 43 is formed integrally with the wire.

For an assembly of the connecting element 40, the insertion openings 32 or 33 can be chosen freely in order to set a distance between the guide element 43 and the holder 10.

In Figure 8A the end portions 41 are inserted into the further outward insertion openings 32, so that the further inward insertion openings 33 remain free. As a result, the guide member 43 is closer to the holder 30 than in the FIG. 8B shown, in which the end portions 41 are inserted into the inner insertion openings 33, which are arranged at a smaller distance than the outer insertion openings 32. The difference in length in the distance between the holder 30 and the guide member 43 is L, for example, depending on the design of the connecting element 20 and the holder 30, a length between 1 mm and 30 mm, in particular 3 to 12 mm, are set.

In the Figures 9A and 9B a further embodiment of a guide device is shown, which, as in the FIGS. 6 to 8 is formed, however, in addition to the bow-shaped guide member 43 has a slider 50. The slider 50 is rotatably mounted on the bow-shaped guide member 43 and has a groove 51 which can be supported on a central vertical web on the rail 6 '. This allows a sliding door 3 are mounted from a front side, wherein during assembly of the central web of the Rail 6 'ensures that the slider 50 is screwed into the groove 7', as in Figure 9A is shown. In the mounted position of the slider 50 is located within the groove 7 'and thus can provide a guide of the sliding door 3 along the rail 6'. The slider 50 has for this purpose a front contact surface 52, which is made for example of plastic and ensures low friction.

In FIG. 10 a modified embodiment of the slider 50 'on the guide member 43 is shown in detail. The slider 50 'can be pivoted about a horizontal axis on the guide member 43, whereby a rigid arrangement is possible. In addition, a horizontally arranged sliding roller 53 is rotatably defined within the slider 50 ', which is mounted in the vertical axis of the slider 50'. In the mounting position of the slider 50 'rolls the outer surface of the sliding roller 53 while the running surfaces of the rail 6 or 6', so that in this way the friction can also be reduced.

In FIG. 11 a modified embodiment of a guide member 43 is shown with sliding sleeves 60, which are arranged around the bendable wire of the connecting element 40. The sliding sleeves 60 are provided on vertical portions of the bow-shaped guide member 43, which provides for a lower friction between the guide member 43 and a rail 6 or 6 '.

In the illustrated embodiments, either portions of the wire of the connecting element or special sliding bodies 50, 50 'or sliding sleeves 60 are provided as guide elements. Of course, it is also possible to provide differently shaped sliding elements as a guide element, which roll on a track of a rail 6 or 6 '. Further, the shape of the sliders may be varied, depending on which shape the rail 6 or 6 'has.

In the illustrated embodiments, the end portions 21 and 41 are respectively fixed to a holder 10 and 30, which is fixed to the sliding door 3. Of course, it is also possible to fix the end sections 21 and 41 on a guide element and to fix a bow-shaped section on the holder 10 or 30. In addition, the shape of the connecting element due to the use of a bendable wire can be changed in order to make a flexible adaptation to the guide device can.
