Description

The invention relates to accessories for a sliding door, characterized by the characteristics given in the restrictive part of claim 1 of the claims.

DE 8135509 describes fittings for a sliding door in which a screw is mounted between two fittings with a recess in the form of a sleeve. A regulating element in the form of a nut is installed on this screw, so that with the help of the specified screw and nuts they can carry out height adjustment. However, such adjustment requires a large number of components and such a device has a limited load capacity. In addition, the screw-nut threaded connection may loosen.

DE 2546384 discloses a detail of accessories for a sliding door, the cup-shaped body of which is recessed in the recess of the sliding door. A running roller is mounted on this part for rotation, which can be inserted into the guide. This hardware part contains means for smooth height adjustment. The hardware part described in this document has the disadvantage that it requires many components, in addition, installing individual parts on a sliding door is a time-consuming operation.

In connection with the foregoing, the objective of the present invention is to create such accessories for a sliding door, which has a compact design and allows a simple way to adjust the height.

This problem is solved thanks to the accessories, characterized by the characteristics described in paragraph 1 of the claims.

In accordance with the invention, a threaded spindle is provided for adjusting in height, which is rotatably mounted in the internal thread of the fastener, and having a support from the end, and at least one fastening means is provided on the fastener adapted to be inserted into the sliding door. Due to this, together with the installation of the fastener, they can fasten the sliding door, which can be adjusted in height with the help of a threaded spindle mounted for rotation on the fastener. Thus, only a few parts are required for fastening the sliding door and adjusting for height, which ensures compact design.

Preferably, at the same time, an integer with a fastener is provided with two pins inserted into the sliding door. Due to this, they can quickly fasten the fastener to the sliding door.

In order to provide height adjustment in a compact manner, the fastener, at least partially, can be inserted into a U-shaped recess in the roller holder. Due to this, the threaded spindle can rest on the bottom of the recess, so that the structural height in the transverse direction is small. In this case, the edge of the recess can be covered by the guide portion of the fastener, so that, thanks to the fastener, they can also carry out the direction in the transverse direction. In this case, the fastener can be made in the form of a die-cast part, which provides a high degree of strength.

Preferably, on both sides of the fastening element there is a guide element to be connected to the sliding door. In this case, the guide element may have at least one protruding slider guided in the elongated hole of the roller holder, so that due to the different guide elements, it becomes possible to transfer the load in several places of the holder. At the same time, in each slider there may be a hole for a mounting screw screwed into the sliding door.

In accordance with yet another embodiment, the sliders are thicker than the travel roller holder in areas adjacent to the sliders, so large friction forces do not occur when adjusting in height.

In order that said accessories can be delivered in the form of a preassembled structural unit, preferably at least one transport fastener is provided on each guide element to lock the guide element on the roller holder. Transport fastening can be performed, for example, in the form of a protrusion, capturing the rear hole in the holder of the roller.
