Abstract:
A suction device assembly comprising:a mouthpiece having a suction sole with an abutment surface defining an abutment surface plane and adapted to engage a plane to be suction cleaned, and an elongated suction slot that debouches on the abutment surface, the mouthpiece defining a plane of reference which is perpendicular to the plane of the abutment surface and extends along with and through the elongated suction slot,a suction pipe having a longitudinal axis, anda connecting element for coupling the mouthpiece with the suction pipe, whereinsaid connecting element comprises a flexible joint adapted to transmit a change of angle of said suction pipe about said longitudinal axis to a rotation of said mouthpiece in said plane of the abutment surface,the flexible joint providing a range of freedom of movement such that said suction pipe may freely assume different orientations relative to said plane of the abutment surface within the range of freedom of movement,the range of freedom of movement allowing said suction pipe to assume an angle of rotation to both sides of said reference plane about an axis parallel with said suction slot, and further allowing said suction pipe to assume an angle in said reference plane which is less than 80 degrees relative to said plane of the abutment surface, and whereinthe flexible joint is adapted in such a manner that a given angle of rotation of said suction pipe about its longitudinal axis causes a substantially equally large angle of rotation of said mouthpiece in said plane of the abutment surface within the whole of said range of freedom of movement.
