DE3101000C2 - Guiding of sliding doors of furniture, in particular cupboards - Google Patents

Abstract

For a sliding door leaf of a piece of furniture, a side guide is provided which is formed by a telescopic rail bent into an arc, the concave side of which faces the interior of the furniture compartment and which is articulated to the furniture at one end about a vertical axis. The other end of the telescopic rail can be pivoted about this axis by means of an extension, which is preferably designed as a three-point folding hinge. When moving from the closed position to the open position, the sliding door leaf therefore also performs a normal horizontal movement component in addition to the laterally directed movement. In the case of two or more sliding doors, adjacent sliding door leaves are in the open position of one sliding door parallel to one another with the same visible surface direction one behind the other.

Description

The invention relates to a guide for sliding doors Suspend ball joints on the body that the sliding door in its open position is parallel to the neighboring Karosseriev / and occupies (DE-AS 22 19 176).

The invention is based on the object of the previously proposed guide for sliding doors of furniture of the type specified above to the effect that the sliding door leaf is in its open position

a piece of furniture takes up less space.

To solve this problem win.! those in claim 1 suggested combination of features. Further advantageous refinements and developments of the invention emerge from the Subclaims.

is limited by the extension, which at the same time supports the telescopic rail in the vertical direction, since the entire weight of the sliding door is in is carried by this extract when open. For this purpose, according to the invention, it is particularly favorable when Extract to use a three-point folding hinge, one wing of which on the cabinet and the other Wing is attached to the telescopic rail.

The guide according to the invention can also be used where the front of the furniture protrudes or has recesses. It needs the swiveling dimension or the curvature of the telescopic rail only to be adjusted according to the dimension of the projection.

Curved telescopic slides can be prefabricated so that the carpentry work can be done on site Body reduced to a minimum. This makes you independent of a precise carpentry work on site and Place, so that the risk of malfunctions is largely avoided. There is also a telescopic rail due to the mutual protection offered by the telescopic rail parts, relatively insensitive to Pollution and damage.

It is also advantageous that the construction according to the invention with any locks and fittings for the door leaf is compatible, so z. B. also with push rod fittings, which are not applicable to the known construction mentioned above.

The telescopic rail is preferably bent into an arc within the scope of the invention, around a to maintain universal applicability.

According to one hamlet of the invention is parallel for the position of the telescopic rail in the open position of the Sliding door in or on the furniture floor has a guide groove or guide rail curved according to the curvature of the telescopic rail for guiding one of the Provided for the lower edge of the sliding door leading Hallers. 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, 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 extension, with particularly simple and operationally reliable means.

Expediently, within the scope of the invention, the telescopic rail has more than one pull-out piece, the individual pull-out pieces overlapping in steps and the sliding door leaf being attached to the last pull-out piece. This means that the telescopic rail can easily be pulled out over long distances. A particularly simple and stable construction is obtained when at least the component of the telescopic rail that encompasses the extension pieces has a U-cross section. whose open side faces the sliding door leaf. Such a U-cross section is very stable and difficult to deform.

If you want. To cover the telescopic sliding door in the open position of the sliding door, the sliding door leaf can be fastened at a distance from the telescopic rail within the scope of the invention, with a cover attached to the telescopic rail covering the telescopic rail being inserted into this distance. - "· r. Abuekrönltes contra-angle can be used.
