Abstract
A sliding element guide system for furniture is provided, including a cabinet unit rail, central rail, sliding element rail, and at least one carriage. The cabinet unit rail, central rail, and sliding element rail are mounted to be movable in relation to one another. The system also includes two identical synchronization wheels that synchronize movements of elements of the system. The two identical synchronization wheels are rotatably mounted on a vertically oriented central rail side wall and extend horizontally therefrom via a pin.
Claims13
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;
- at least one carriage including bearing elements;
- and
- two identical synchronization wheels, each being spaced apart from one another on opposite sides of the central rail, and each being rotatably mounted on a vertically oriented central rail side wall via a respective pin extending horizontally from the vertically oriented central rail side wall, so that the two identical synchronization wheels are present and mutually spaced apart on parallel side wall portions of the central rail,
- 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,
- wherein the two identical synchronization wheels synchronize a movement of the cabinet unit rail with a movement of the sliding element rail,
- wherein the two identical synchronization wheels are spaced apart on mutually opposite end sides of the central rail or on mutually opposite external sides of the central rail,
- 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 a plane of extent of a raceway of a first sliding element rail side wall portion in relation to a plane of extent of a 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 180°, and/or
- wherein a plane of extent of a raceway of a first cabinet unit rail side wall portion in relation to a plane of extent of a 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 180°.
