A door roller includes a carriage member comprising a plurality of bores, and a plurality of roller assemblies connected to the carriage member, each roller assembly of the plurality of roller assemblies including a pivot bearing rotatably disposed within a bore of the plurality of bores and a pair of rollers coupled to the pivot bearing. Each wheel assembly is configured to pivot relative to the carriage member.

A guide apparatus for guiding a furniture part, in particular a sliding door or folding-sliding-door, including a guide rail and a chassis which can be connected to the furniture part and which can travel on the guide rail. The chassis has a load-bearing roller, mounted about a first rotation axis, for supporting the weight of the furniture part and a supporting roller for laterally guiding the furniture part. The supporting roller is rotatably mounted about a second rotation axis which is oriented transverse to the first rotation axis, and a support apparatus is separate from the at least one supporting roller, and is designed to relieve the supporting roller in an end position of the at least one guide rail against a transverse force acting laterally, i.e. substantially parallel to the first rotation axis.

A retention and guide assembly for a vehicle door includes a guide track connected to a door panel of the vehicle door. The guide track includes sidewalls that at least partially extend around and define an internal recessed volume. The sidewalls include a first sidewall coupled with the door panel and a second sidewall coupled with and oriented transverse to the first sidewall. The guide track includes a retaining flange that is coupled with and oriented transverse to the second sidewall. The sidewalls and the retaining flange are shaped to receive (within the internal recessed volume) a roller of a control arm extending from a vehicle body. The retaining flange engages the control arm and/or the roller and retain the roller within the internal recessed volume of the guide track between the second sidewall and the door panel of the vehicle door.

A furniture drive system includes a mechanical control unit having a pivotably mounted control arm for moving a movable furniture part, a spring device for applying force to the control arm, and a movably mounted control part having a transmission opening for transmitting a force from the spring device to the control arm. An electrical drive unit has an electric motor for moving the movable furniture part, and a driver to be driven by the electric motor for transmitting a torque of the electric motor to the mechanical control unit. The driver can be inserted into the transmission opening, and the electrical drive unit and the mechanical control unit are designed as separate assemblies and can be fastened to each other. A contact surface for the driver is arranged laterally adjacent to the transmission opening and the driver is preloaded toward the contact surface by a force store.
