Abstract: A rolling device having a bearing housing accommodating a wheel axle, a drive motor with first and second motor parts for conduction of relative rotation between a wheel element and the wheel axle, end portions of the wheel axle being connected to axle support members in an eccentric position displaced from the center line of the axle support members, and locks operable between an unlocked position allowing rotation of the axle support members relative to the bearing housing, and a locking position preventing the rotation of the axle support members, wherein in the unlocked position, the motor conducts rotation of the axle support members and wheel axis for displacement of the wheel element by an eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.

Abstract: The invention concerns a drive unit for moving a door relative to a door's opening. The drive unit comprises a drive motor and a wheel transmission assembly arranged for transfer of power to a drive wheel configured for engagement with a running surface for moving the door. The wheel transmission comprises a transfer wheel driven by the drive motor. A movable wheel carrier comprises a first running wheel and a second running wheel arranged in in engagement with the transfer wheel. The movable wheel carrier is arranged for displacement between a free wheel position where the first and second running wheel are arranged disengaged from the drive wheel for no power transfer to occur from the drive motor to the drive wheel, at least one running position where either of the first and second running wheel is positioned in engagement with the drive wheel for the transfer of power from the drive motor to the drive wheel.

Abstract: A rolling device for a device that is to be moved along a surface is described. The rolling device comprises a cylinder with an opening at one end and a piston that is arranged reciprocally movably in the cylinder such that the piston can be moved between an upper position in the cylinder and a lower position in the cylinder. The piston comprises a rolling element that is arranged in a first end portion of the piston that faces the cylinder opening and that rolls on the surface when the device is to be moved. The rolling device further comprises an actuator system for movement of the piston between the upper position and the lower position in the cylinder.
