Description

The present invention relates to a fitting for a sliding door according to the preamble of claim 1.

The DE 81 35 509 U1 discloses a fitting for a sliding door in which a screw is received between two fitting parts with a sleeve-shaped embossing. The adjusting element is arranged on the screw in the form of a nut, so that a height adjustment can be carried out by means of the screw and the nut. Such a height adjustment requires numerous components and has only a limited load capacity. There may also be loosening of the screw connection with the nut.

The DE 25 46 384 A1 discloses a fitting for a sliding door that is sunk into a recess in the sliding door with a cup-shaped housing. On the fitting part a roller is rotatably mounted, which can be hung on a rail. The fitting part includes means for infinitely variable height adjustment. The hardware part shown has the disadvantage that numerous components are necessary and the assembly is also complex in order to mount the individual parts on the sliding door.

It is therefore an object of the present invention to provide a fitting for a sliding door which is of compact construction and enables simple height adjustment.

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

According to the invention, a threaded spindle is provided for the height adjustment, which is rotatably mounted in an internal thread of the holding element and is supported on the end face on the roller carrier, at least one fastening means which can be inserted into a sliding door being provided on the holding element. As a result, the sliding door can be fixed integrally with the holding element and can be adjusted in height via the threaded spindle rotatably mounted on the holding element. As a result, only a few components are required for the mounting of the sliding door and the height adjustment, which allow a compact structure.

Two pins which can be inserted into the sliding door are preferably provided integrally with the holding element. This allows the holding element to be fastened to the sliding door quickly.

For a compact height adjustment, the holding element can be at least partially inserted into a U-shaped recess on the roller carrier. As a result, the threaded spindle can be supported on a bottom of the cutout, so that there is a small installation height in the lateral direction. The edge of the recess can be encompassed by a guide section on the holding element, so that lateral guidance can also be obtained by the holding element. The holding element can be made as a die-cast part, which ensures a high degree of stability.

A guide element which can be connected to the sliding door is preferably provided on both sides of the holding element. The guide element can have at least one protruding sliding block, which is guided in an elongated hole on the roller carrier, so that a force transfer by different guide elements is made possible at several points on the roller carrier. An opening for a fastening screw can be provided on each sliding block, which is then screwed into the sliding door.

According to a further embodiment, the sliding blocks are made thicker than the roller carrier, which is formed adjacent to the sliding blocks, so that no high frictional forces occur during the height adjustment.

In order to be able to deliver the fitting as a preassembled unit, at least one transport lock is preferably provided on each guide element, which secures the guide element on the roller carrier. The transport lock can be designed, for example, as a projection which engages behind an opening on the roller carrier.
