Description

This invention relates to a guide for a sliding door, comprising a guide element adapted to be displaced along the rail, a holder adapted to be fixed to the sliding door, and a connecting piece for connecting the holder to the guide element, as well as a method for mounting the sliding door.

From DE 10 2010 037 940, a roller guide for a sliding door is known, in which a guide roller is rotatably mounted on a lever system having a guide lever and a supporting lever pivotally connected to each other. Thus, the guide roller moves along the rail with spring loading, which makes it possible to compensate for tolerances and ensures ease of installation. However, such a lever system requires a large number of components.

In this regard, the objective of this invention is to create a guide device for a sliding door, which is easy to install and contains a small number of components. In addition, the object of the present invention is to simplify the installation of a sliding door on a cabinet, etc.

This problem is solved in the sending device with the signs of paragraph 1 of the formula and the method with the signs of paragraph 13 of the formula.

In accordance with the invention, the guide device comprises a guide element, a holder and a connecting piece for connecting the holder to the guide element, the connecting part comprising a flexible wire. Thus, the guide can be assembled from a small number of components. In addition, the use of a flexible wire makes it possible to adapt flexibly to other installation widths of the guide device. This creates variability in terms of using different lengths. In addition, turning the guide through the flexible wire makes it easier to assemble the door.

Preferably, the connecting piece between the guide member and the holder comprises at least two parts of a flexible wire that are spaced apart. As a result, these two parts separated from each other can be differently oriented, for example, to adjust the distance between the holder and the guide element. In addition, the rotation of the connecting element around the axis of the wire is prevented. The connecting piece allows you to adjust the distance between the guide element and the holder by the elastic bending of the wire, and for the most part this bending occurs in the field of flexible deformations. As far as possible, bending in the area of plastic deformations should be avoided. For flexible adjustment of the distance between the holder and the guide element, the flexible wire may have two end parts attached in different positions to the holder or guide element. To secure the end portions of the flexible wire, installation holes or sockets can be provided so as to ensure ease of installation.

Preferably, the two flexible wire portions intersect so that these intersecting portions can be oriented at different angles in order to change the length of the connection part.

In a preferred embodiment of the invention, the flexible wire in the lateral projection, when viewed in the longitudinal direction of the rail, is U-shaped, the holder being formed or mounted on the first shelf and the guide element on the second shelf.

The guide element can be mounted on a flexible wire bracket or formed integrally with this bracket. In this case, the guide element can be held on this bracket in a rotating manner, which will facilitate installation from the front of the furniture case.

For ease of installation of the fastener, it can be rotatably mounted on a horizontal axis on the holder. In addition, the connecting piece can be latched in its mounting position on the holder.

The connecting piece can also be composed of several flexible wires connected to each other either by means of additional components or by means of common technological processes.

The flexible wire material is preferably metal, but in this case plastic is also applicable.

The guide device according to the invention is applicable, in particular, in furniture with a sliding door, but it may have other uses.

In the method according to the invention, for mounting the sliding door on a furniture cabinet, a holder is fastened first on the sliding door, on which is placed a guide element that is designed to be displaced along the bottom rail. Then the sliding door is hooked into the upper rail and the guide member is moved relative to the holder to insert the guide member into the groove on the lower rail. This makes it easier to install the sliding door. If a flexible wire is used as a connecting piece, damage can be prevented by placing it on the base.

Further, the invention is explained in more detail with reference to examples of its implementation, shown in the accompanying figures of the drawings, where:

- FIG. 11 is a perspective view of a modified guide.

Cabinet 1 includes a furniture body 2, on which the first sliding door 4 and the second sliding door 3 are mounted. For this purpose, the upper rail 5 is installed on the main upper part and the lower rail 6 of the proposed guide device is mounted on the furniture body 2.

As shown in FIG. 2, the bottom rail 6 has grooves 7 and 8 open to the bottom, and in the groove 7 a guide element connected to the second sliding door 3 is meshed.

FIG. 3A and 3B, the holder 10 and the guide piece 20 are shown in detail. The holder 10 is made in the form of a plate part in which there are two holes 11 for inserting screws for mounting to the sliding door 3. In addition, on the underside of the holder 10 there are flanges 12 provided with a corresponding slot 13 for inserting the end portion 21 of the connecting piece 20. Sockets 13 are formed, respectively, on both sides of the holder 10.

The connecting piece 20 is made of flexible wire, for example, made of metal, in particular stainless steel. The connecting part 20 comprises end portions 21 inserted into sockets 13 on the holder 10 and fixed in them. In this case, the part 24 of the wire that passes from the front side of the holder 10 is held in the locking nest 14, so that the connecting piece 20 can be mounted on the holder 10 in a certain position. The connecting piece 20 also has two distinct parts 22, extending substantially horizontally from the holder 10 to the guide element 23, which in this embodiment is formed integrally from a flexible wire extending substantially vertically upward into the groove 7 of the rail 6. As shown in FIG. 3B, thus the connecting piece 20 in the lateral projection, in the longitudinal direction of the rail 6, is given a substantially U-shaped profile. The holder 10 is located on one shelf of this U-shaped profile, while the guide element 23 is formed integrally with the wire on the opposite side. In order to install the connecting piece 20, it can be inserted into the holder 10 when it is attached to the back side of the sliding door 3. Similarly, the connecting piece 20 can be inserted into the holder 10 and before mounting the holder 10 on the sliding door 3.

FIG. 4 shows a modified embodiment of the connection piece 20 ', in which, in contrast to the embodiment of FIG. 3A-3B, the portions 22 'between the holder 10 and the guiding element 23 intersect each other. The rest of the connecting part 20 'and the holder 10 is made as in the previous version.

FIG. 5A and 5B show the installation of the connecting piece 20 on the sliding door 3. First, the end portions 21 are inserted into the sockets 13, then the connecting piece 20 is rotated around a horizontal axis formed by the end portions 21. Then the portion 24 is latched onto the locking socket 14 on the holder 10 as shown in fig. 5B. The two parts 22 are thus oriented essentially horizontally, and the clamp-shaped guide element 23 is inserted substantially vertically into the open bottom 7 of the groove 7, thereby preventing the sliding door 3 from moving in a horizontal direction, perpendicular to the longitudinal direction of the rail 6.

When during installation the sliding door 3 is placed on the floor, the connecting piece 20 cannot damage the floor, since the connecting piece 20 can, if necessary, be turned further upwards - as shown in FIG. 5C. Then the flexible wire is removed from the locking socket 14 and turned up. This reliably prevents plastic deformation of the fastener 20 and damage to the floor, which is impossible in the case of guide elements made from angular sheet metal known from the prior art.

FIG. 6 shows a modified embodiment of a guide device in which a modified holder 30 and a modified connecting piece 40 are provided. The holder 30 is made in the form of a plate part and contains two openings 31 in which you can insert screws for fastening to the sliding door 3. On the back side of the holder 30 facing the sliding door 3, there are mounting holes 32 and 33 into which the end portions 41 of the connecting piece 40 can be inserted. The connecting piece 40 is again made of bent wire, having a circular cross-section, with the connecting piece comprising vertical end portions 41 and two horizontal portions 42 spaced from each other, which are connected to each other by a clamp-shaped guide element 43. The guide member 43 is integrally formed with the wire.

For mounting the fastener 40, the mounting holes 32 or 33 can be freely selected to set the distance between the guide member 43 and the holder 10.

FIG. 8A, end portions 41 are inserted into mounting holes 32 located closer to the outside, so that mounting holes 33 located closer to the inside remain free. As a result, the guide member 43 is closer to the holder 30 than in the position shown in FIG. 8B, when the end portions 41 are inserted into the inner mounting holes 33 located at a smaller distance than the outer mounting holes 32. The difference in length between the holder 30 and the guide member 43 is L, therefore, depending on the configuration of the connecting piece 20 and the holder 30 the length can be set, for example, between 1 mm and 30 mm, in particular from 3 to 12 mm.

FIG. 9A and 9B show another embodiment of the guide device, which is designed in the same way as in FIG. 6-8, but additionally contains a slider 50 on a clamp-shaped guide member 43. The slide 50 is mounted rotatably on the clamp-shaped guide member 43 and has a groove 51 which can rest on the middle vertical rail shelf 6 '. Thus, the sliding door 3 can be mounted from the front side, and during installation, due to the middle shelf of the rail 6 ', the slider 50 is screwed into the groove 7' - as shown in FIG. 9A. In the mounted position, the slider 50 lies within the groove 7 ', thereby ensuring the direction of the sliding door 3 along the rail 6'. For this purpose, the slider 50 includes a front contact surface 52, made for example of plastic and provides low friction.

FIG. 10 shows in detail a modified embodiment of the slider 50 'on the guide member 43. The slider 50' can be rotated on the guide member 43 about a horizontal axis, with rigid installation also possible. In addition, inside the slider 50 'is mounted for rotation horizontally located guide roller 53, mounted on the vertical axis of the slider 50'. In the mounting position of the slider 50 ', the outer surface of the guide roller 53 rolls along the rolling surface of the rail 6 or 6', thereby reducing friction.

FIG. 11 shows a modified embodiment of the guide member 43 with sliding sleeves 60, which are located around the flexible wire of the connecting piece 40. Sliding sleeves 60 are provided on the vertical parts of the brace guide member 43, which provides lower friction between the guide member 43 and the rail 6 or 6 '.

In the shown embodiments, either parts of the connecting piece wire, or special sliders 50, 50 ', or sliding sleeves 60 are used as guide elements. Obviously, sliders of various designs, rolling along the rail track 6 or 6', are applicable as guide elements. In addition, the shape of the sliders may vary depending on the shape given to the rail 6 or 6 '.

In the illustrated embodiments, the end portions 21 and 41 are attached, respectively, to the holder 10 or 30, which is attached to the sliding door 3. Obviously, the end portions 21 and 41 can also be attached to the guide element, and the bracket part to the holder 10 or 30 In addition, the shape of the connection piece can be changed in accordance with the application of a flexible wire, in order to provide a flexible fit to the guide device.
