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.

Roller carriage for the reception of a sliding door having at least two mounting devices

A roller carriage for the reception of a sliding door includes a roller module for a displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The roller carriage includes a lift-off protection device for the protection against removal of the roller module out of the displaceable affixing at the roller running path. The lift-off protection device includes a lift-off protection element which is supported to be movable between a protection position and a release position, as well as an arresting device for an arresting of the lift-off protection element at least in the protection position.

Roller carriage for the reception of a sliding door with a lift-off protection device

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.

Roller carriage for the reception of a sliding door with a height adjusting device

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 roller module is configured of a first material and the basic body of a second material. The first material conducts structure-borne sound in a first sound conducting range and dampens the structure-borne sound in a second sound conducting range. The second material dampens structure-borne sound in the first sound conducting range and conducts structure-borne sound in the second sound conducting range.

Roller carriage for the reception of a sliding door

An adjusting and interlocking unit for displaceable and pivotable doors and/or walls, which are guided to be movable at and/or in a roller rail via rollers, includes an upper part, attachable to the roller rail, a central part attachable to a movable carriage profile of a door respectively of a wall, and a lower part attachable to the door, respectively to the wall. A locking element allows for releasing or interlocking the doors and/or wall.

Arresting and interlocking unit for a partition wall system, as well as a partition wall system

The invention is directed to a holder for fixedly attaching a panel to a substructure. The holder comprises a connection member capable of being fixedly connected non-rotatably to the substructure, a panel holder fixedly attached to the panel and a spacer element threadedly attaching the connection member to the panel holder. The spacer element can be axially adjusted and fixed relative to the connection member and the panel holder.

Plate holding device fixed to a substructure

A clamp fixture to fasten glass plates that are clamped between an inner clamp element and an external clamp element, whereby a clamp bolt is supported elastically, to a limited extent, on the inner clamp element by means of a bush. The invention teaches that the inner clamp element, on the side facing the substructure, has a cylindrical receptacle space to hold the bearing that supports the clamp bolt in the axial direction, whereby the bearing is realized optionally in the form of a fixed bearing, in the form of a friction bearing that intersects the center longitudinal axis of the clamp bolt, or in the form of a movable bearing for the four-point bearing of a glass plate.

Clamp fitting for fastening glass plates

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. Furthermore, there are a first lock strike box and a second lock strike box, effectively connected to each other by means of a closing cylinder through a boring contained in the fixed glass side panel. The dead bolt is supported ready for locking action in the second lock strike box, whereby a catch for the latch bolt is contained in the first lock strike box.
