Abstract

For a sliding-door leaf of a piece of furniture, the invention provides a side guide which is formed by a telescopic rail which is bent to form a bow, the concave side of which is directed towards the interior of the furniture compartment, and which, at one end, is connected to the piece of furniture such that it can be articulated about a vertical axis. The other end of the telescopic rail can pivot about said axis by means of a pull-out extension which is preferably formed as a three-point hinge. When transferring from the closed position into the open position, the sliding-door leaf thus also carries out, in addition to the laterally directed movement, a horizontal movement component at right angles thereto. In the case of two or more sliding doors, neighbouring sliding-door leafs are located, in the open position of one sliding door, parallel to one another and one behind the other with the visible surfaces in the same direction.

Description

Guide for sliding doors of furniture,

especially cupboards The invention relates to on a guide for sliding doors of furniture, especially cupboards, with a Lateral guide for the sliding door leaf, which is assigned a pull-out, so that the Sliding door leaf when it is moved from the closed position to the open position in addition to the lateral movement along the side guide, there is also a horizontal movement Movement component performs normally, and in the case of two or more sliding doors in the open position of one sliding door, adjacent sliding door leaves are parallel stand one behind the other with the same visible surface direction.

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 on one Arranged pull-out that can be moved normal to the longitudinal direction of the side guide, wherein in the outer end position of the pull-out a groove carried by it in the side guide with another groove arranged in the area of the adjacent sliding door Lateral guide is in alignment. The sliding door is along these side guides Moved to her attached roles. Such constructions have fundamentally proven, but have certain requirements that their application is not always and make it possible anywhere without any problems. So the known constructions set a relative exact work in advance, as it will not be possible if it is not carefully processed or

Adjustment of the side guides for clamping the sliding door comes.

Furthermore, the known construction can only be used where the neighboring ones Lateral guides can be attached flush with each other, which is the case with built-in cupboards, for example with cabinet compartments offset from one another in the direction of the cabinet depth the case is.

The object of the invention is to provide guidance for the above-mentioned Art to be designed in such a way that the construction becomes more independent of precise carpentry work and above all can be used where adjacent furniture compartments are not aligned Have front. The invention solves this problem in that as a side guide a telescopic rail bent into an arc is provided for the sliding door leaf is whose concave side faces the furniture interior and which is on your one End is articulated around a vertical axis with the furniture, whereas you other The end can be pivoted about this axis by means of the extract. So while the known construction described at the outset, the transfer from the closed position the sliding door in its open position takes place in that first the pull-out in Depth direction of the furniture pulled out and then the sliding door to the side, normal to it is moved, the subject of the invention has a different movement: First, is the pushed together telescopic rail together with the door leaf carried by it around the Articulation axis pivoted so that the vertical edge of the remote from the articulation axis Door leaf protrudes from the furniture compartment. Then the telescopic rail is pulled out moves the sliding door leaf along the curved path of the telescopic rail, wherein the curvature of the telescopic rail has the consequence that after performing the mentioned Pivoting inclined sliding door leaf approximately or exactly parallel to the The front of the furniture comes to stand in front of the adjacent compartment. The pivoting movement the telescopic rail around its articulation axis is limited by the excerpt, the at the same time forms a support for the telescopic rail in the vertical direction, since the The entire weight of the sliding door when open is borne by this pull-out will. For this purpose it is particularly advantageous according to the invention to use a three-point folding hinge as a pull-out to use the wing attached to the cabinet or to the telescopic rail are.

The invention is also applicable where the front of the furniture Has protrusions or recesses. In the case of protrusions, the swivel dimension or the curvature of the telescopic rail is only adjusted according to the size of the projection to become.

The invention is also very suitable for series furniture, since none Special constructions are necessary for the installation.

Telescopic rails with curvature can be prefabricated so that the carpentry work on site is reduced to a minimum. So that will you are much more independent of a precise carpentry work on the spot, so that the risk of malfunctions is significantly reduced. Also is a telescopic rail as a result of the mutual protection of the telescopic rail parts offer, relatively independent of dirt and damage.

It is also advantageous that the construction according to the invention with any Locks and fittings for the door leaf are compatible, e.g. also with push rod fittings, which are not applicable to the known construction mentioned at the beginning.

The telescopic rail is within the scope of the invention preferably to one Arc of a circle bent in order to obtain universal applicability.

According to a development of the invention is parallel to the position of the Telescopic rail in the open position of the sliding door in or on the furniture floor guide groove or guide rail curved according to the curvature of the telescopic rail intended to guide a holder leading to the lower edge of the sliding door.

This avoids pendulum movements of the sliding door leaf and the sliding door leaf is always held vertically. The holder is useful here guided by a roller in the guide groove or guide rail in order to reduce friction.

It is advisable to design the extension as a three-point folding hinge, whose legs are attached to the furniture or to the telescopic rail. This results in the desired guide for the pivotable about the axis by means of the pull-out End of the telescopic rail with particularly simple and reliable means.

Appropriately within the scope of the invention, the telescopic rail has more than a pull-out piece, with the individual pull-out pieces overlapping in a stepped manner and the sliding door leaf is attached to the last pull-out piece. This can do a lot large extension paths of the telescopic rail can be managed without any problems. One special simple and stable construction results when at least the pull-out pieces encompassing component of the telescopic rail has U-cross section, the open side of which the Sliding door leaf is facing. Such a U-section is very stable and heavy to deform.

If desired, the telescopic slide in the open position of the To cover sliding door, the sliding door leaf can be spaced within the scope of the invention be fastened by the telescopic rail, with a telescopic rail in this distance covering panel attached to it protrudes. For this Spacer an angled elbow can be used with advantage.

In the drawing, the subject matter of the invention is based on an exemplary embodiment shown schematically. Fig. 1, 2 and 3 each show in horizontal section 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.

Fig. 5 shows a vertical section through the for holding the door leaf Serving telescopic rail, 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 one Position of the telescopic rail. Fig. 7 is a section along the line VII-VII 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, which are laterally limited by two side heads 4, 5 and a central head 6. 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 locked. Fig. 2, however, shows a position of the sliding door panel 7 in which this sliding door leaf is pivoted about an axis 9 in the direction of arrow 12 is that the side edge of the sliding door panel 7 shown on the right in FIG the compartment 2 protrudes. 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. Besides, this is respective sliding door leaf 7 or 8 along the extension direction of the telescopic rail 10 laterally displaceable, so that e.g. the sliding door panel 7 from the one shown in FIG Position brought into the position shown in FIG. 3 in the direction of arrow 11 can be. In the latter position, the sliding door leaf 7 lies 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 accurate or approximate is parallel to the sliding door leaf 8, the telescopic rail 10 is curved, preferably along an arc of a circle, the concave side of this curvature being the respective one Closet compartment is facing.

4 to 8 show the construction and fastening of the telescopic rail 10 shown in more detail Each telescopic rail 10 consists of a casing part 13 and two pull-out parts 14, 15 mounted therein and in one another so as to be longitudinally displaceable, with 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 bodies, 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. On the pull-out part 15 the respective sliding door panel 7 or 8 is suspended, namely by means of two cranked elbows 18 (Fig.7), so that the sliding door panel 7 and 8 in one Distance a from the telescopic rail 10 is attached to this. In the thereby formed A diaphragm 20 protrudes into the gap 19 and is fastened to the upper edge of the telescopic rail 10 and covers it when the sliding door is open.

The telescopic rail 10 is on its side main 4 or

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

The telescopic rail 10 has a U-shaped cross section Shell part 13 and a first pull-out part also formed with a U-cross section 14. The last pull-out part 15 can be full, but possibly also from one Be formed U-rail. The described training as U-rails guaranteed however, a high stability and a high deformation resistance of the relevant Components.

To swivel movements of the respective sliding door leaf 7 respectively.# in order to prevent the longitudinal axis of the telescopic rail 10, each sliding door leaf carries 7 or 8 at 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 in the ground 33 of the respective cabinet compartment 2 or 3 is arranged. The guide groove 32 runs over the entire width of the respective compartment 2.3 through, parallel to the Course of the jacket part 13 of the telescopic rail 10 in the open position of the door leaf 7 or 8 associated position.

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

Of course, the invention is also applicable to cabinets or

other pieces of furniture with more than two compartments can be used are and the compartments do not have to be of the same width and with their fronts also not be arranged in alignment.

The extension formed by the three-point folding hinge 22 for the telescopic rail 10 could also be designed in another way, e.g. also as a telescopic rail which is articulated to the main 6 or to the telescopic rail 10. The design of this extract as a three-point folding hinge 22, however, has the advantage that thereby the on the hinge 21 from the weight of the sliding door panel 7 and 8 exercised moments can be better absorbed.

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