Sliding element guide system

A sliding element linear guide system for a furniture item or a domestic appliance, the sliding element linear guide system comprising:

• a cabinet unit rail;
• a central rail;
• a sliding element rail;
• a carriage including bearing elements, wherein the carriage comprises a first carriage associated with the cabinet unit rail and the central rail, and a second carriage associated with the sliding element rail, and wherein the cabinet unit rail, the central rail and the sliding element rail are movably mounted such that the cabinet unit rail, the central rail and the sliding element rail are moveable in relation to one another;
• and
• synchronization means having a synchronization element, wherein the synchronization means synchronizes movement of elements of the sliding element guide system,
• wherein the synchronization element comprises two identical synchronization elements rotatably disposed on the central rail,
• wherein the two identical synchronization elements are configured to be spaced apart on mutually opposite end sides of the central rail or on mutually opposite external sides of the central rail,
• wherein the cabinet unit rail and the sliding element rail are configured to have a C-profile-shape,
• wherein the cabinet unit rail has a cabinet unit rail horizontal wall portion and two cabinet unit rail side wall portions that are mutually spaced apart,
• wherein the sliding element rail has a sliding element rail horizontal wall portion and two sliding element rail side wall portions that are mutually spaced apart,
• wherein the sliding element rail side wall portions and/or the cabinet unit rail side wall portions comprise a planar raceway for the synchronization elements,
• wherein a plane of extent of the raceway of the sliding element rail side wall portion and/or a plane of extent of the raceway of the cabinet unit rail side wall portion extends along a longitudinal extent of the rail elements,
• wherein the central rail runs between the cabinet unit rail side wall portions and/or the sliding element rail side wall portions,
• wherein an internal angle α between a plane of extent of a central rail horizontal wall portion and a plane of extent of a central rail side wall portion is in a range of 30° to 70°,
• wherein the plane of extent of the raceway of a first sliding element rail side wall portion in relation to the plane of extent of the raceway of a second sliding element rail side wall portion encloses a sliding element rail angle δ, wherein the sliding element rail angle δ is in an angular range between 0° and less than 180°, and/or
• wherein the plane of extent of the raceway of a first cabinet unit rail side wall portion in relation to the plane of extent of the raceway of a second cabinet unit rail side wall portion encloses a cabinet unit rail angle β, wherein the cabinet unit rail angle β is in an angular range between 0° and less than 180°.
