  • 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.

  • Publication number: 20080163579
    Abstract: A single-point holder for fixing a glass pane relative to a sub-construction or support is disclosed. The holder includes two clamping fittings for clamping the glass pane therebetween, one of the clamping fittings comprising a hollow sphere bearing shell; a setting member connectable to the one of the two clamping fittings; and a connecting component connectable to the sub-construction or support and having a longitudinal axis, the connecting component comprising a ball head which is received in the hollow sphere bearing shell. The hollow sphere bearing shell is divided into first and second semi-spherical bearing shells in a plane normal to the longitudinal axis of the connecting component. The first and second semi-spherical bearing shells and the ball head form a ball-and-socket joint. When connected to the one of the two clamping fittings, the setting member sets and fixes the first and second semi-spherical bearing shells relative to each other.

  • Patent number: 6449994
    Abstract: A door lock for an all-glass door with an adjacent fixed glass side panel. In this case, the door lock is attached through a boring contained in the all-glass door and basically presents a dead bolt, a latch bolt and a follower. Furthermore, a lock strike box is mounted through a boring contained in the glass side panel at the height of the door lock. Furthermore, the door lock comprises a first lock casing arranged on one side of the all-glass door and a second lock casing placed opposite to the first lock casing on the other side of the all-glass door. The first lock casing comprises the latch bolt and the second lock casing comprises the strike plate for the dead bolt.
