Patent ID: 8727837

Claim:
A rotatable disc head for a floor treatment device, the rotatable disc head comprising: a pair of coupling members pivotably connected to each other according to pivot axes transversely oriented with respect to each other, a rotation axis transversely oriented with respect to said pivot axes, said coupling members being furthermore connected to each other by means of at least one elastically deformable connection element, wherein one of the coupling members comprises fitting means for mounting said coupling member to a rotary drive of the floor treatment device and the other coupling member comprises carrier means onto which a floor treatment element can be mounted, wherein an intermediate member is provided which is coupled to one of the coupling members through one of the pivots and which is coupled to the other of the coupling members through the other pivot, wherein multiple connection elements are provided at a distance from at least one of the pivot axes, and wherein a connection between the connection element and one coupling member are slideable connections allowing displacements which are oriented transversely with respect to the rotation axis.
