  • Patent number: 10392844
    Abstract: A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door, wherein at least two mounting devices are provided for realizing respectively one mounting function of the roller carriage. Each mounting device includes at least one mounting element with a manipulation interface for applying a mounting force for performing a mounting movement of the mounting element. The manipulation interfaces of the mounting elements of the at least two mounting devices are disposed on a first side of the roller carriage, and a bearing device of the roller module for the displaceable affixing at the roller running path is disposed on the opposing second side of the roller carriage.

  • Patent number: 9915087
    Abstract: A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The basic body is supported at the roller module to be displaceable along a direction of gravity (SKR) for a fine-tuning movement, wherein a first adjusting component for an adjusting movement is supported at the basic body to be movable. For a movement of the basic body along a direction of gravity in relation to the roller module when performing the adjusting movement, the first adjusting component is in operative connection with a second adjusting component of the roller module.
