Description

The invention relates to a guide for sliding doors 55 of furniture, in particular cupboards, with a side guide for the sliding door leaf, which is associated with an extract, so that the sliding door leaf when moving from the closed position to the open position in addition to the lateral movement along the side guide horizontal movement component 50 normally performed, and in the open position of the one sliding door adjacent sliding door leaves are parallel to each other and with the same direction of view behind each other.

Such guides for sliding doors of furniture, especially cupboards, are known (AT-PS 339532 and 352936). In 65 of these known constructions, the side guide is arranged on a pull-out which can be displaced normally to the longitudinal direction of the side guide, with the

Excerpt aligns a groove of the side guide carried by him with another groove of the side guide arranged in the area of the adjacent sliding door. The sliding door is moved along these side guides with rollers attached to it. Such constructions have proven themselves in principle, but have certain requirements that do not always make their application possible without problems. The known constructions therefore require relatively precise work, since the sliding door may become jammed if the side guides are not carefully processed or adjusted. Furthermore, the known construction is only applicable where the adjacent side guides can be installed in alignment with one another, which, for. B. is not the case in built-in cabinets with offset cabinet compartments in the direction of the cabinet depth.

The object of the invention is to design a guide of the type described in the introduction in such a way that the construction becomes more independent of precise carpentry work and above all can also be used where adjacent furniture compartments do not have an aligned front.

The invention solves this problem in that a telescopic rail bent into an arc is provided as the side guide for the sliding door leaf, the concave side of which is turned towards the interior of the respective furniture compartment and is connected at one end to the furniture in an articulated manner about a vertical axis its other, free end about this axis can be pivoted to a limited extent by the extension. Thus, while in the known construction described at the outset, 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 laterally moving the sliding door normally, the movement of the subject of the invention is different: First, the telescopic rail pushed together, together with the door leaf carried by it, is pivoted about the articulation axis in such a way that the vertical edge of the door leaf facing away from the articulation axis protrudes from the furniture compartment. Then, pulling the telescopic rail, the sliding door leaf is moved along the curved path of the telescopic rail, the curvature of the telescopic rail having the result 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 neighboring compartment. The pivoting movement of the telescopic rail around its articulation axis is limited by the pull-out, which at the same time forms a support for the telescopic rail in the vertical direction, since the entire weight of the sliding door is borne by this pull-out in the open state. For this purpose, it is particularly advantageous according to the invention to use a three-point hinged hinge as an extension, one of whose outer legs is attached to the furniture and the other to the telescopic rail.

The invention can also be used where the front of the piece of furniture has protrusions or recesses. In the case of projections, the pivoting dimension or the curvature of the telescopic rail only needs to be adjusted in accordance with the dimension of the projection. The invention is also very suitable for series furniture, since no special constructions are required for the installation.

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

It is also advantageous that the construction according to the invention is compatible with any locks and fittings for the door leaf. B. also with push rod fittings, which at

known construction mentioned above are not applicable.

In the context of the invention, the telescopic rail is preferably bent into an arc in order to obtain universal usability. 5

According to a development of the invention, parallel to the position of the telescopic rail in the open position of the sliding door in or on the furniture floor, a guide groove or guide rail curved in accordance with the curvature of the telescopic rail is provided for guiding a holder guiding the lower edge of the sliding door. As a result, pendulum movements of the sliding door leaf are avoided and the sliding door leaf is always kept vertical. The holder is expediently guided with a roller in the guide groove or guide rail in order to reduce the friction. 15

It is expedient to design the pull-out as a three-point hinge, the legs of which are attached to the furniture or to the telescopic rail. This results in the desired guidance for the end of the telescopic rail which can be pivoted about the axis by means of the pull-out, with particularly simple and operationally reliable means.

In the context of the invention, the telescopic rail expediently has more than one pull-out piece, the individual pull-out pieces overlapping one another in steps and the sliding door leaf being fastened to the last pull-out piece. As a result, very large pull-out paths of the telescopic rail can be easily mastered. A particularly simple and stable construction results if at least the component of the telescopic rail U encompassing the pull-out pieces has an open cross-section facing the sliding door leaf. Such a U-cross section is very stable and difficult to deform.

If it is desired to cover the telescopic rail in the open position of the sliding door, the sliding door leaf can be attached at a distance from the telescopic rail within the scope of the invention, with a telescopic rail 35 covering and attached to it protruding into this distance. A bent elbow can be used to advantage for this spacer.

In the drawing, the subject of the invention is shown schematically using an exemplary embodiment. Fig. 1,2 and 3 40 show in horizontal section through a cabinet, the principle of the invention 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. 5 shows a vertical section through the telescopic rail used to hold the door leaf, with the door leaf removed, in the pushed-together 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 of Fig. 5 and Fig. 8 is a section along the line

VIII-VIII of Fig. 4.

The cabinet 1 shown in FIGS. 1 to 3 has two compartments

2,3, which are laterally delimited by two side heads 4,5 and a center head 6. The two compartments 2, 3 can each be closed by a sliding door, the sliding door leaves 7 and 8 of which are shown in FIG. 1 in the position in which the two compartments 2, 3 are closed. FIG. 2, on the other hand, shows a position of the sliding door leaf 8 in which this sliding door leaf is pivoted about an axis 9 in the direction of the arrow 12 such that the side edge of the sliding door leaf 8 shown on the left in FIG. 2 protrudes from the compartment 3 60. Each sliding door leaf 7 or 8 is supported by a telescopic rail 10 and can be pivoted together with the latter about the axis 9. In addition, the respective sliding door leaf 7 or 8 is laterally displaceable along the extension direction of the telescopic rail 10, so that e.g. the sliding door leaf 8 can be moved from the position shown in FIG. 65 to the position shown in FIG. 3 in the direction of arrow 11. In the latter position, the sliding door leaf 8 lies in front of the sliding door leaf 7 and

55

compartment 3 is freely accessible. In order to ensure that the sliding door leaf 8 lies exactly or approximately parallel to the sliding door leaf 7, the telescopic rail 10 is curved, preferably along an arc, the concave side of this curvature being turned towards the respective cabinet compartment.

4 to 8, the construction and fastening of the telescopic rail 10 is shown in more detail. Each telescopic rail 10 consists of a casing part 13 and two pull-out parts 14, 15 mounted therein and one inside the other in a longitudinally displaceable manner, 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) , so that the pull-out parts 14, 15 can be easily pulled out or pushed in again. The respective sliding door leaf 7 or 8 is suspended in the pull-out part 15, namely by means of two angled angle pieces 18 (FIG. 7), so that the sliding door leaf 7 or 8 is attached to the telescopic rail 10 at a distance a. A diaphragm 20 protrudes into the gap 19 formed thereby, which is attached to the upper edge of the telescopic rail 10 and covers it when the sliding door is open.

The telescopic rail 10 is articulated at its end facing the side head 4 or 5 of the respective compartment 2 or 3 by means of a hinge 21 on the respective side head 4 or 5, which hinge 21 forms the axis 9. The end of the jacket part 13 of each telescopic rail 10 facing away from the hinge 21 is fastened to the center head 6 by means of a three-point folding hinge 22. The three-point hinged hinge 22 has four legs 23, 24, 25, 26 in a known manner, which are connected to one another by hinge axes 27, 28, 29. 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 leaf 8 shown in FIG. 4, which is shown in the open position of the compartment 3, the legs 24, 25 are, however, stretched. The respective leg 23 is attached to the center 6, the leg 26 to the jacket part 13 of the telescopic rail 10.

The telescopic rail 10 has a jacket part 13 designed with a U-cross section and a first pull-out part 14 also designed with a U-cross-section. The last pull-out part 15 can be full, but may also be formed by a U-rail. However, the design described as U-rails ensures high stability and a high resistance to deformation of the components in question.

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

The closed position of the sliding door leaf 7 shown in FIG. 4 for the compartment 2 or the open position of the sliding door leaf 8 can be determined in a manner known per se by fixing members, e.g. Magnetic snappers, be assured that B. try to keep the three-point hinge 22 in its collapsed position shown for the door leaf 7 in Fig. 4 or in the extended position shown for the door leaf 8.

Of course, the invention can also be applied to cupboards or other pieces of furniture which are provided with more than two compartments, and the compartments do not have to be of the same width and also not aligned with their front fronts.

The pull-out hinge 22 formed by the three-point hinge 22 for the telescopic rail 10 could also in other ways, for. B. also be designed as a telescopic rail, which is articulated to the main 6 or to the telescopic rail 10. The

652 795

However, designing this pull-out as a three-point hinged hinge 22 has the advantage that the moments exerted on the hinge 21 by the weight of the sliding door leaf 7 or 8 can be better absorbed.

Instead of a guide groove 32 provided in the furniture floor 33, a guide rail placed on the floor 33 and fastened thereon can also be used for guiding the holder 30.
