Description

The present invention relates to a fitting for a sliding door, in particular for furniture, according to the preamble of Anspurches. 1

The DE 20 2005 007 687 discloses a sliding door fitting with a roller supported on a rail having a C-shaped profile on a lower leg. On the upper leg a safety catch is provided which engages under the leg with a projection, thereby preventing a lifting of the fitting from the rail. This safety catch requires a C-shaped rail profile, so that use for other rails is not possible.

The AT 410 820 discloses a sliding door fitting in which a roller is supported on a rail. On the roller a bendable lever is arranged from a sheet metal part, which can be bent over another lever to the outside. The bendable lever has a hook portion which engages under the rail for a safety catch. However, the bendable design of the lever has the disadvantage that after repeated use it can happen that the lever is no longer located below the rail. In addition, the design of the lever as a thin-walled sheet metal part causes the hook portion of the lever is bent at higher forces and the safety catch is no longer given.

In the DE 20 2009 005 269 U1 a running part for a sliding door is shown, in which below a track of a running rail a securing device is arranged with a rocker, which prevents lifting of the sliding door leaf in a locking position.

It is therefore an object of the present invention to provide a fitting for a sliding door in which the safety catch avoids a safe lifting the sliding door and also a simple operation is ensured.

This object is achieved with a fitting with the features of claim 1.

According to the invention, the safety catch comprises a rotatably mounted lever with an actuating portion and a hook portion which engages under a head portion of the rail in a securing position. By the rotatably mounted lever is avoided that by bending material fatigue affect the functioning of the safety catch. The rotatable mounting ensures a defined position of the lever in the securing position and also the lever with the hook portion can have a stable structure.

Preferably, the lever can be locked in the securing position. As a result, an unintentional release of the lever is avoided and the user receives the optical and / or acoustic feedback when closing the lever that the securing position is reached. The lever can additionally be latched in an unlocking position in which the roller can be lifted off the rail. As a result, after the lever has been pivoted into an unlocking position, the user can now unhook it after unlocking the at least two fittings on the sliding door.

According to the embodiment of the invention, an axis disposed on the lever between the actuating portion and a rail engaging under the hook portion is arranged. As a result, the lever is designed as a kind of "rocker", which is pivotable between two positions. This allows a compact design and it can be provided low pivoting. The lever can be rotatably mounted on an axis which is formed on a bearing element that is connected to the holder.

According to a further embodiment, an adjusting mechanism is provided, by means of which the position of the holder relative to the mounting element in height is adjustable. As a result, an alignment of the sliding door can also be done after hanging. The adjusting mechanism preferably comprises a rotatably mounted on the holder threaded rod, which passes through the bearing element for rotatably supporting the lever.

For a stable design of the lever this is designed as a plastic part. In this case, at least one latching means for fixing the lever in the securing position and / or the unlocking position is integrally formed with the plastic part. The locking means may cooperate with a further locking means on the bearing element, which may also be formed as a plastic part.
