A system includes a docking station, for location on a surface to be worked, and a self-propelled working tool. The station has a primary transmission part. The tool has a body, a surface-engaging wheel, and a secondary transmission part. The station and the tool can establish contact with each other and the tool can drive up to the station and achieve a docking position wherein the transmission parts contact and cooperate. In one aspect, the secondary transmission part is located on an upper portion of the body. In another aspect, the station includes a part spaced upwardly away from the surface, with the primary transmission part located thereon and directed downwardly. In another aspect, a portion of the body is located beneath a portion of the part upon which the primary part is located and the wheel remains engaged with the surface when in the docking position.

Docking system for a self-propelled working tool

A docking system ( ) which essentially comprises at least one docking station ( ) for at least one self-propelled working tool ( ), and includes the working tool ( ) itself, preferably intended for attendance of ground or floor, such as grass-cutting, moss-scratching, watering, vacuum-cleaning, polishing etc. The docking station and the tool can by way of emitted signals establish contact with each other, so that the tool can drive up to the docking station, and the docking station is provided with at least one first transmission part ( ) for transmission of energy and/or information between the docking station and the working tool, which is provided with at least one co-operating second transmission part ( ). The docking station is designed as a base plate ( ), intended to be placed on ground or floor, and provided with at least one rising part ( ), of which at least one part is used for mounting of the transmission part(s), and the docking station is so adapted that the tool with any part, such as wheel(s) ( ), or body ( ), can drive up on the docking station.
