Description

The present invention relates to a holding element for holding guide rails for sliding doors of a piece of furniture according to claim 1.

Guide devices for sliding doors are known in various designs. In general, such guide means comprise a guide rail and a slide door side attachable guide member such. B. a roller. As shown, for example, in EP 1 057 963 A2, the local guide rail has a C-shaped fastening groove in which a fixing plug can be arranged with a head in order to fasten the guide rail in a furniture carcass. Such attachment of the guide rail is relatively easy to install and leads to a complicated shape of the guide rail.

EP-0501191 discloses a holding element having the features of the preamble of claim 1.

It is therefore an object of the present invention to provide a holding element for holding guide rails of sliding doors, which holds a guide rail, especially with a high weight of the sliding doors, with a simple structure and simple cost manufacturability, and by which the distance between the guide rail and furniture body is easily adjustable.

This object is achieved by a holding element having the features of claim 1. Advantageous developments are the subject of the dependent claims.

It is thus proposed a holding element for holding a guide rail for sliding doors in furniture, which consists of a holding part and a base part. The holding part and the base part are connected to each other in such a way that they are adjustable relative to each other in the axial direction of the holding element. The holding part has a receiving area to hold the guide rail. The base part is further attachable to a furniture body. Thus, a holding member is provided, which is simple in construction and can securely hold a guide rail. Further, an adjustment of the distance of the guide rail to the furniture body by an arranged between the holding part and the base member adjustment is possible by the holding element. In this case, an adjustment can also be made with mounted holding element or mounted guide rail. By this measure, a tolerance compensation is possible.

According to the invention it is proposed that a union nut is used, which is rotatably attached to the holding part and has an internal thread which is screwed onto an external thread of the base part. To counter the holding part and thus fixing the nut is located in the base part a lock screw, which is adjustable against the bottom of the holding part. Also in this case, the adjustment of the retaining element from the outside is not visible. For alignment and thus correction (in the longitudinal extent) of tolerances, the rod contained in the holding part can be brought by means of the lock screw in the correct position.

Preferably, the receiving area of the holding part is circular. As a result, in particular a cylindrical guide rail can be held by the retaining element.

According to a preferred another embodiment of the present invention, the receiving portion of the holding member is formed as a pitch circle. The pitch circle is larger than a semicircle. This can prevent that a cylindrical guide rail can be inadvertently removed from the receiving area, since the receiving area of the holding part engages around the guide rail by more than half the circumference. The guide rail (rod) can be removed only in their axial directions.

Particularly preferably, the pitch circle is open in the axial direction of the retaining element. This ensures that when using castors, the displacement of the sliding door or the run of the roller on the guide rail is not disturbed by the retaining element when the retaining element is attached to an upper or lower surface of a furniture body.

According to another preferred embodiment of the present invention, the pitch circle of the receiving area is open perpendicular to the axial direction of the holding element. As a result, the holding element can be arranged on a front region of a furniture body, without any movement of a roller on the guide rail being hindered by the holding element.

In order to enable a simple and secure attachment of the guide rail in the receiving area of the holding element, the guide rail is preferably fixed by means of a grub screw. This can be visible from the side or invisible in the axial direction.

Particularly preferably, the guide rail is designed as a cylindrical rod.

In order to enable a simple attachment of the base part of the holding element to a furniture body, the base part preferably has a passage opening in which a fastening element such. B. a screw is added. Thus, the base part can be easily attached to the furniture body.

Since the holding element according to the invention is designed to be particularly stable due to its structure, it is particularly suitable for the use of heavy sliding glass doors. In the holding elements known hitherto, such use of heavy sliding glass doors is only possible to a limited extent since the full weight of a sliding glass door usually leads to problems, in particular due to the load caused by the displacement. Also, the retaining element for vertical mounting of a rod to z. B. to connect several furniture carcasses with each other.

Hereinafter, a holding member will be described according to a non-inventive first embodiment with reference to Figures 1 to 5c.

As shown in FIG. 1, by way of example, a guide device has two guide elements, which are designed as cylindrical rods 6. A sliding door 1 is slidably mounted on the rods 6 via four rollers 3. The rollers 3 are fastened by means of punctiform fastening elements 5 on the sliding door 1. The sliding door 1 is designed as a glass door and has through openings through which the fastening elements 5 are inserted in order to secure the rollers 3. The fasteners close flush with the outer top of the glass sheet 1.

As shown in Figure 1, the two rods 6 are arranged on the furniture body 2, that a first rod 6 is fixed to an upper portion of the furniture body 2 and a second rod 6 at a lower portion of the furniture body 2. The rods 6 are fastened by means of retaining elements 7 on the furniture body 2. As can be seen in particular from FIG. 1, an adjustable stop 13 is provided on the upper rod 6 at its two lateral ends, in order to limit a displacement path of the sliding door 1. The stop is mounted directly on the rod 6 and limits the displacement of the rollers 3 to the right or left.

As shown in particular in FIGS. 2 a to 2 e and 3 a to 3 d, the holding element 7 consists of three parts, namely a holding part 8 which has an external thread and a receiving area 9 for the bar 6 (see Figure 3), a base part 10 which is fixed to the furniture body 2, and a lock nut 11. The base part 10 and the lock nut 11 are screwed onto the external thread portion of the holding part 8. The rod 6 is fixed by means of a grub screw 12 in the receiving region 9 of the holding part 8 (see Figure 2d). The holding element 7 in particular allows a height adjustment of the rod 6 by the holding part 8 is screwed into the base part 10 or unscrewed from this. As a result, the distance between the rod 6 and the furniture body 2 is changed. The final position of the holding element 7 can then be secured with the lock nut 11. This makes it possible that the rod can still be aligned in a simple manner, especially after installation.

As shown in particular in FIG. 1, the rods 6 are fastened via the retaining elements 7 to an upper region or lower region of the furniture body 2. This makes it possible that the sliding door 1 can be arranged in only a small distance to the open area of the furniture body 2.

As can also be seen from FIGS. 2c and 3c, the receiving area 9 of the holding part 8 for receiving the bar 6 is designed such that it has two arcuately formed arms which project beyond a central axis of the bar 6. Thereby, the rod 6 can not be taken out of the holding elements 7 up or down, but must always be led out in the direction of its longitudinal axis from the holding elements 7.

Furthermore, the distance of the sliding door 1 to the furniture body 2 by arranging washers between the fastening element 5 and the rollers 3 can be changed in a simple manner.

In the figures 2a to 2e, the holding member 7 according to the first embodiment is shown in detail. As shown in the figures, the holding element 7 comprises the holding part 8, the base part 10 and the lock nut 11. As can be seen in the perspective view of Figure 2a and the side view of Figure 2c, in the holding part 8 in particular a receiving area 9 for receiving the Bar 6 is formed. In this case, the outer diameter of the rod 6 is slightly smaller than the inner diameter of the receiving region 9. The receiving region 9 is designed as a pitch circle, which is opened in the axial direction X-X of the holding element 7. Since the pitch circle of the receiving area 9 is larger than a semicircle, a rod 6 held by the receiving area 9 can not be removed in the direction X-X. The rod must always be in its longitudinal axis, d. H. taken perpendicular to the axis X-X in the direction Y-Y (see Figure 2b).

A grub screw 12, which is inserted into a threaded bore 14 which is formed in the receiving region 9 (see FIGS. By means of the grub screw 12, the rod 6 can be clamped in the receiving area 9 against the wall of the receiving area, so that they can no longer move in the direction of their longitudinal axis Y-Y.

The holding part 8 of the holding element 7 is again shown in detail in Figures 3a to 3d. As shown there, the holding part 8 has a threaded portion 20. The assembly of the retaining element can be seen in particular from the exploded view in Figure 2e. First, the lock nut 11 is screwed onto the threaded portion 20 of the holding member 8. Subsequently, a screw 19 is guided from the inside through the opening 17 of the base part 10.

By this screw 19, the base part, as shown in Figure 1, are attached to a furniture body 2. Preferably, the opening 17 is designed as a slot, so that an optimal alignment of the base part 10 on the furniture body 2 can be achieved. Subsequently, the holding part 8 provided with the screwed-on lock nut 11 is screwed into the internal thread 18 of the base part 10 (see FIG. 5c). In this case, the height of the holding element 7 can be set arbitrarily. When the intended height is reached, the position can be secured by means of the lock nut 11. As shown in Figures 4a, 4c and 4d, the lock nut 11 has two flattened portions 15 to allow easy attachment of a tool. After the successful assembly of the holding element 7, the rod 6 is guided in the receiving area 9 and fixed by means of the grub screw 12 at the desired position.

Thus, a simple structure retaining element for a guide device for sliding doors can be provided, which is simple and stable and allows a height adjustment of the retaining element 7 in its axial direction X-X. It should be noted that the holding part 8 may also be formed with a through hole in the direction X-X, so that the screw 19 can be fixed by this through hole on the furniture body.

Hereinafter, a holding member will be described according to a non-inventive second embodiment of the present invention with reference to Figures 6a to 7d. Identical or functionally identical parts are denoted by the same reference numerals as in the first embodiment.

As can be seen in particular from FIGS. 7a to 7d, in contrast to the first exemplary embodiment in the second exemplary embodiment the holding part 8 is formed with an annular receiving area 9. In other words, the receiving region 9 is no longer part-circular, but formed completely circular, so that it completely surrounds a rod 6. The rod is fixed again by means of a grub screw 12 in the receiving area 9. Otherwise, the second embodiment corresponds to the first embodiment, so that reference can be made to the description given there.

In the figures 8a to 9c, a holding element according to a third embodiment not according to the invention is described. Identical or functionally identical parts are denoted by the same reference numerals as in the first embodiment.

As shown particularly in FIGS. 8b and 8d, in the third exemplary embodiment, the holding part 8 is again formed with a part-circular receiving area 9, similar to the first embodiment. In contrast to the first embodiment, however, the receiving area 9 is arranged such that the free area is not in the direction of the axis X-X, d. H. in the longitudinal direction of the holding element, is directed, but is directed at 90 ° perpendicular to the axis X-X. Thereby, the holding element 7 according to the third embodiment is particularly suitable to be arranged on the front sides of furniture carcasses 2, so that a rod arranged in the receiving area 9 is supported both from the sides and from below. Otherwise, the holding element 7 according to the third embodiment corresponds to the holding element described in the previously described embodiments, so that can be dispensed with a further description.

FIGS. 10 to 13 describe a holding element according to an exemplary embodiment of the present invention. Same or Functionally identical parts have been designated by the same reference numerals as in the preceding embodiments.

The holding part 21 shown in Figures 10 to 13 is characterized in that a holding part 8 is provided in a similar manner with a receiving area 9, as in the previous embodiments. On the holding part 8 directed towards a base member 23, a union nut 22 is present, which is supported on the one hand to the holding part and on the other hand rotatably secured by a locking ring 27 on the holding part 8. The union nut is reproduced in a separate representation of FIG. In this case, the union nut 22 is designed so that it has a through hole 31 which penetrates the union nut 22 over a short area and then ends in an undercut 32 having a larger diameter. On the other hand, to the undercut, a bore 33 with a thread 24 adds. The thread 24 is screwed onto the base part 23.

The base part 23 is shown separately in FIGS. 14 and 15. Analogous to the base part 10, the base part 23 on a through hole 17 in order to accomplish an attachment of the base part 23 to a furniture body. Following the bore 17, a bore with an internal thread 26 connects. On the outer circumference of the base part 23, a thread 25 is provided, which serves for screwing the nut 22.

For mounting, the base part 23 is connected by means of a screw 19 through the through hole 17 with the furniture body. In order to accomplish a height adjustment of the inserted into the receiving area 9 rod 6, a counter-screw 28 is screwed into the base 26 in the thread 26. By means of this lock screw 28 can be a height adjustment and thus a stop for the holding part are formed. If the height adjustment carried out, the union nut 22 is screwed to the holding part 8 on the base part 23. In this case, the union nut 22 can be screwed as far as the base member 23 until a base 34 of the holding member 8 comes into contact with the lock screw 28. At the same time, the cap nut 22 is pulled against the retaining ring 27 of the holding part 8 by this position, which ensures a backlash-free attachment of the holding part 8 with the base part 23.

In order to fix the rod 6 in the receiving portion 9 of the holding part, on the one hand there is a possibility of a laterally located in the holding part 8 grub screw 12 within a threaded bore 14 or an invisible attachment of the rod 9 via a grub screw 29 extending in the axial direction of the holding part 21 (extends). In this case, the rod 9 would have to be done before mounting the nut 22 on the base part 23.

As the figure 10 also makes clear, is located on the base part 23, a collar 30 for resting on the furniture body, which has the same diameter as the union nut 22. As a result, a slender, no frills retaining element 21 is reproduced.

Thus, the present invention relates to a holding element 21 for holding a guide rail 9 for sliding doors, especially sliding glass doors, with a holding part 8 and a base part 10. The holding part 8 and the base part 10 are connected to each other such that they are mutually adjustable in the axial direction XX of the holding element are. The holding part 8 has a receiving area 9 in order to hold a guide rail 9. The base part 10 is z. B. by means of a screw 19 on the furniture body 2 fastened.
