Suction attachment for a vacuum cleaner
First Claim
1. A suction attachment for a vacuum cleaner comprising:
- a suction nozzle;
a coupling member for coupling the suction attachment to a suction channel of the vacuum cleaner, said coupling member being pivotable relative to the suction nozzle about a pivot axis extending perpendicularly to a main displacement direction of the suction attachment;
a first and a second brush extending near, respectively, a front edge and a rear edge of the suction nozzle;
an adjustment mechanism for adjusting the first and the second brush from a first position, in which the first and the second brush are in a retracted position relative to a bottom surface of the suction nozzle, into a second position, in which the first and the second brush are in a protruding position relative to said bottom surface;
and a rolling member arranged near said pivot axis in such a position that, during operation, said rolling member is in contact with a surface to be cleaned when the first and the second brush are in said first position, and said rolling member is not in contact with the surface to be cleaned when the first and the second brush are in said second position;
characterized in that, seen in the main displacement direction, said pivot axis is arranged between the first brush and at least a portion of the second brush.

Abstract
The invention relates to a suction attachment (9) for a vacuum cleaner. The attachment comprises a suction nozzle (11) and a coupling member (21) by means of which the attachment can be coupled to a suction channel (15) of the vacuum cleaner. The coupling member is pivotable relative to the suction nozzle about a pivot axis (33) which extends perpendicularly to a main displacement direction (X) of the attachment. The suction nozzle comprises a first brush (47) and a second brush (51) which extend near, respectively, a front edge (41) and a rear edge (43) of the suction nozzle (11). The suction nozzle further comprises an adjustment mechanism (55, 57) by means of which the first and the second brush can be adjusted from a first position, in which the first and the second brush are in a retracted position relative to a bottom surface (45) of the suction nozzle, into a second position, in which the first and the second brush are in a protruding position relative to said bottom surface. The attachment further has a rolling member (35) which is arranged near said pivot axis. On a carpet, the first and the second brush are in the first retracted position and the rolling member is in contact with the carpet to provide a supporting force. On a hard floor, the first and the second brush are in the second protruding position and the rolling member is not in contact with the surface (5) to be cleaned in order prevent bad manoeuvrability of the attachment on the hard floor. According to the invention the pivot axis (33) is arranged, seen in the main displacement direction (X), between the first brush (47) and at least a portion (77, 79) of the second brush (51). In this manner a stable position of the suction nozzle (11) on a hard floor is achieved, i.e. when the rolling member (35) is not in contact with the hard floor.
