Description

The innovation relates to a guide for sliding doors of furniture, especially cupboards, with a side guide for the sliding door leaf to which an extract is assigned, so that the sliding door leaf is transferred from the In the closed position into the open position, in addition to the lateral movement along the side guide, there is also a horizontal movement component normal to this, and in the case of two or more sliding doors in the open position of one sliding door neighboring sliding door leaves parallel to each other stand one behind the other in the same direction of the visible surface.

Such guides for sliding doors of furniture, especially cupboards, are known (AT-PS 339 532 and 352 936). In these known constructions, the side guide is arranged on a pull-out that is normal to the longitudinal direction of the side guide is displaceable, and in the outer end position of the pull-out a groove carried by the side guide with it Another groove of the side guide arranged in the area of the adjacent sliding door is aligned. Along these side guides the sliding door is moved with rollers attached to it. Such constructions have fundamentally tried and tested, but have certain requirements that do not allow them to be used always and everywhere without any problems. So the known constructions require a relatively precise work, because if the work is not done carefully or Adjustment of the side guides for clamping the sliding door comes. Furthermore, the known construction is only applicable where the adjacent side guides can be installed in alignment with each other, which means Z = B = for built-in cupboards with each other in Cabinet compartments offset in the direction of the cabinet depth is not the case.

The innovation has the task of designing a guide of the type described above so that the construction It becomes more independent of precise carpentry work and can be used, above all, where adjacent furniture compartments are not aligned Have front. The innovation solves this problem in that as a side guide for the sliding door leaf a sheet curved telescopic rail is provided, the concave side of the Furniture interior is facing and at one end to one

vertical axis is articulated to the furniture, while its other end can be pivoted about this axis by means of the extension. While in the known construction described at the beginning, the transfer from the closed position of the sliding door to its open position takes place by first pulling out the pull-out in the depth direction of the furniture and then moving the sliding door to the side in a normal manner the collapsed telescopic rail together with the | The door leaf is pivoted about the articulation axis so that the vertical edge of the door leaf facing away from the articulation axis protrudes from the furniture compartment. The sliding door leaf is then moved along the curved path of the telescopic rail while extending the telescopic rail, the curvature of the telescopic rail having the consequence that the sliding door leaf, which is inclined after the aforementioned pivoting, comes to be approximately or exactly parallel to the front of the furniture in front of the adjacent compartment. The pivoting movement of the telescopic rail about its pivotal axis is limited by the hiebei extract, at the same time the educational a support of the telescopic rail in the vertical direction * det, since the whole weight of the sliding door in the open inlet \

stand is borne by this excerpt. For this it is according to the innovation particularly cheap, a three-point folding hinge as a pull-out to use the wings of which are attached to the cabinet or to the telescopic rail.

The innovation can also be used where the front of the furniture has protrusions or recesses. With protrusions the swiveling dimension or the curvature of the telescopic rail only needs to be adjusted according to the dimension of the projection. The innovation is also very suitable for series furniture, as no special constructions are required for installation.

Telescopic rails with curvature can be prefabricated, ¹ so that the carpentry work on site is reduced to a minimum. This makes you much more independent of a precise carpentry work on site, so that the risk of malfunctions is significantly reduced. In addition, a telescopic rail is relatively independent of each other due to the mutual protection offered by the telescopic rail parts

Pollution and damage.

It is also advantageous that the construction according to the innovation with any locks and fittings for the door leaf is compatible, e.g. also with push rod fittings, which cannot be used in the known construction mentioned at the beginning are.

As part of the innovation, the telescopic rail is preferably bent to form an arc of a circle in order to be universally usable to obtain.

According to a further development of the innovation, the sliding door is parallel to the position of the telescopic rail in the open position in or on the furniture floor a guide groove or guide rail for guidance that is curved according to the curvature of the telescopic rail a holder leading to the lower edge of the sliding door is provided. This prevents the sliding door leaf from swinging and the viewing door leaf is always held vertically. The holder with a roller in the guide groove or Füh = is useful here guide rail to reduce friction.

It is useful to use the pull-out as a three-point folding hinge train whose legs are attached to the furniture or to the telescopic rail. This results in the desired guidance for the end of the telescopic rail that can be pivoted around the axis by means of the extension with particularly simple and reliable ones Means.

As part of the innovation, the telescopic rail expediently has more than one pull-out piece, with the individual pull-out pieces overlap in steps and the sliding door leaf is attached to the last pull-out section. This allows very large pull-out paths the telescopic rail can be easily mastered. A particularly "* simple and stable construction results if at least the component of the telescopic rail encompassing the pull-out pieces has a U-shaped cross-section, the open side of which is the sliding door leaf is facing. Such a U-cross section is very stable μ and difficult to deform.

If it is desired to cover the telescopic rail in the open position of the sliding door, the innovation the sliding door leaf must be fastened at a distance from the telescopic rail, with a telescopic rail at this distance

ne covering panel attached to it protrudes. A cranked angle piece can advantageously be used for this spacer be used.

In the drawing, the subject of the innovation is shown schematically on the basis of an exemplary embodiment. Figs. 1, 2 and each show in a horizontal section through a cabinet the innovation principle in three different operating positions of the Sliding door. Fig. 4 shows on a larger scale a horizontal section through the cabinet in the open position of the sliding door. Fig. 5 shows a vertical section through the for holding the Telescopic rail serving the door leaf, with the door leaf removed, in the closed position of the telescopic rail. FIG. 6 is a section similar to FIG. 5, but in the extended position of the telescopic rail. Fig. 7 is a section along the line VII-VII in FIGS. 5 and 8 is a section along the line VIII-VIII in FIG. 4.

The cabinet 1 shown in Figs. 1 to 3 has two compartments 2, 3 ^ by two side heads 4, 5 and a central head 6 are laterally limited. The two compartments 2, 3 can each be closed by a sliding door, the sliding door leaves of which 7 and 8 are shown in Fig. 1 in the position in which the two compartments 2, 3 are closed. Fig. 2 shows on the other hand, a position of the sliding door leaf 7 in which this sliding door leaf is about an axis 9 in the direction of the arrow 12 • is pivoted so that the side edge shown on the right in Fig. 2 of the sliding door leaf 7 protrudes from the compartment 2. Each sliding door leaf 7 or 8 is on a telescopic rail 10 and can be pivoted about the axis 9 together with the latter. In addition, the respective sliding door panel 7 or 8 is along the extension direction of the telescopic rail 10 laterally displaceable, so that, for example, the sliding door leaf 7 from the one shown in FIG Position can be brought into the position shown in FIG. 3 in the direction of arrow 11. In the latter The sliding door leaf 7 is positioned in front of the sliding door leaf 8 and compartment 2 is freely accessible. In order to ensure that the sliding door panel 7 is exactly or approximately parallel to the Sliding door leaf 8 lies, the telescopic rail 10 is curved, preferably along an arc of a circle, the concave side

this curvature facing the respective closet compartment.

4 to 8, the construction and fastening of the telescopic rail 10 is shown in more detail. Any telescopic rail 10 consists of a casing part 13 and two pull-out parts 14, 15 » the pull-out part 14 in the casing part 13 and the pull-out part

15 in the pull-out part 14 by means of rolling elements, in particular balls

16 and 17 (Fig. 7) are mounted so that the pull-out parts 14, 15 can be easily pulled out or pushed back in. The respective sliding door leaf 7 or 8 is suspended on the pull-out part 15, namely by means of two cranked angle pieces 18 (Fig. 7), so that the sliding door panel 7 or 8 is attached to the telescopic rail 10 at a distance a from the latter is. A screen 20, which is fastened to the upper edge of the telescopic rail 10, protrudes into the gap 19 thus formed and covers it when the sliding door is open.

The telescopic rail 10 is at its end facing the side main 4 or 5 of the respective compartment 2 or 3 by means a hinge 21 is articulated to the respective side main 4 or 5, which hinge 21 forms the axis 9. That the Hinge 21 facing away from the end of the shell part 13 of each telescopic rail 10 is by means of a three-point hinged hinge 22 on Central head 6 attached. The three-point folding hinge 22 has, in a known manner, four legs 23, 24, 25, 26, which are connected by hinge axes 27, 28, 29 are connected to one another. The door leaf 7 shown in Fig. 4 is in a closed position, in which the legs 24, 25 lie flat against one another. For the sliding door panel 8 shown in Fig. 4, which is in the The open position of the compartment 3 is shown, the legs 24, 25 are, however, stretched. The respective leg 23 is on the middle main 6 attached, the legs 26 on the shell part 13 of the telescopic rail 10. ..

The telescopic rail 10 has a / U-shaped cross section Shell part 13 and a first pull-out part 14, also formed with a U-cross section. The last pull-out part 15 can be full, but optionally also be formed by a U-rail. The training described as U-rails guaranteed but a high stability and a high

resistance to deformation of the components concerned.

In order to prevent the respective sliding door leaf 7 or 8 from pivoting about the longitudinal axis of the telescopic rail 10, each sliding door leaf 7 or 8 carries on its lower edge a holder 30 formed by an angle (FIG. 8) on which a roller 31 is mounted which runs in a guide groove 32 which is arranged in the floor 33 of the respective cabinet compartment 2 or 3. The guide groove 32 runs over the entire width of the respective compartment 2, 3, parallel to the course of the casing part 13 of the telescopic rail 10 in the position associated with the open position of the door leaf 7 or 8.

The closed position of the sliding door leaf 7 or the open position of the sliding door leaf shown in FIG. 4 for the compartment 2 8 can be secured in a manner known per se by means of fixing devices, e.g. magnetic catches, e.g. the three-point hinged hinge Looking to hold 22 in its collapsed position shown in FIG. 4 for the door leaf 7 or in the stretching position shown for the door leaf 8.

Of course, the innovation is also applicable to Schrärike or other pieces of furniture that have more than two Alb parts are provided and the compartments do not have to be of the same width and their fronts do not have to be aligned.

The excerpt formed by the three-point folding hinge 22 for the telescopic rail 10 could also be designed in another way, for example also as a telescopic rail, which is connected to the main 6 or is articulated to the telescopic rail 10. the Training this excerpt as a three-point hinged hinge 22 has the advantage that this means that on the hinge 21 from Weight of the sliding door leaf 7 or 8 moments exerted can be better absorbed.

Instead of a guide groove 32 provided in the furniture base 33, a guide groove 32 placed on the base 33 and fastened to it can also be used Guide rail can be used to guide the holder 30.
