Description

  The present invention relates to a sliding door roller guide according to the premise structure of claim 1 and an arrangement of the sliding door roller guide in the storage furniture according to the premise structure of claim 16.

  In order to move at least two sliding doors that close the storage furniture, guide rails are arranged in the upper region and the lower region of the furniture, and the sliding door roller guides mesh with the guide rails. One of these two sliding doors covers the other in the open posture.

  To attach the rear door that is closest to the furniture body and is covered by the front door in the open position, the rear door is moved toward the guide rail in the lower area and lifted to move the roller guide to the lower guide rail Next, the upper region is guided laterally with respect to the moving direction toward the upper guide rail, and the roller of the lower sliding door roller guide is guided laterally with respect to the moving direction by the wall of the lower guide rail. Meanwhile, the upper region is lowered so that the upper sliding door roller guide is supported by the corresponding guide rail.

  Since the rear and front doors overlap in the closed peripheral areas in the closed position, the attachment can only be done in the manner described above by inserting the front door outside the covering area. In this operation, the front door protrudes laterally beyond the side wall of the furniture body during installation, and the installation of the furniture in the depression is practically impossible when the distance between the side wall and each wall is short.

  In particular, it is difficult to attach a heavy sliding door, which takes at least time and labor.

  Although a structure in which the front door can be directly attached from the front side is known, these methods including, for example, an additional spring part can be realized only when considerable efforts are made in terms of manufacturing technology in view of the concept.

Depending on the turning motion. A guide element is introduced into the elongated hole. The guide element may be formed by a fixing element such as a pin integrally formed on the lever or a screw provided on the lever, for example.

  In order to simplify the mounting of the lever system, the slot is open towards the free end of the support opposite the fixing plate so that the fixing element can be easily inserted into the slot. The fixing element may also be formed as a pin provided with a mushroom-shaped head formed integrally with the lever.

  The restriction of the swivel path of the lever system, which is necessary in the direction of the slot insertion opening and prevents the guide element from sliding out of the slot, is preferably formed into a ramp and is one of the lever arms. In connection with the fixed stop, this is done by means of an oblong restricted track provided in the support. The limiting track and stop are dimensioned to accommodate the maximum possible pivoting of the lever system.

  The elongated hole for receiving the guide element may expand in accordance with the movement of the joint shaft that connects the two lever arms to each other. At this time, the guide element substantially forms an extension of the pivot shaft, or one of the lever arms is provided with a separate guide element outside the joint shaft, and the guide element is a holder. It is introduced into the long hole formed corresponding to.

  The lever arm is preferably made of plastic, and the spring element is preferably formed integrally with the lever arm in a thin and annular shape. Alternatively, or in addition, a separate spring element may be provided. In this case, a predetermined force for holding the door on the guide rail is applied according to the dimensions of the spring element.
