Embodiment Construction

[0017] Referring now to the accompanying drawings in detail, figure 1 A front brush attachment comprising a multi-part housing 1 in the form of a suction head is shown. The housing 1 has a chassis 2 , an upper part 3 which is fixedly connected to the chassis 2 and a cover 4 which extends over the upper part 3 . The housing 1 comprises a brush roller chamber 5 which is open at its bottom and a dust suction channel 6 which leads into the brush roller chamber 5 . The dust suction channel 6 and the brush roller chamber 5 are formed by the walls of the upper part 3 and the chassis 2 . A brush roller 7 is rotatably supported in the brush roller chamber 5 . The brush roller 7 is driven by an electric motor 8 via a toothed belt 9 .

[0018] A connecting device connects the vacuum cleaner to the casing 1 . The connecting device is a rotating and pivoting joint 10 . The pivoting and pivoting joint 10 has a pivoting joint part 11 which is inserted into the suction duct 6 . The swiv...

Abstract

A front brush attachment device for a vacuum cleaner comprises a multi-component housing, a rotationally driven brush roller, and a rotating and tilting joint for connecting the vacuum cleaner. The rotating and tilting joint has a tilting joint piece inserted in a suction duct of the housing, as well as a short, rotatable joint tube, which is connected with the tilting joint piece in a rotating manner. The tilting joint piece is supported in the housing in a manner permitting it to revolve about an axle aligned transversely in relation to the suction duct. The short, rotatable joint tube is mounted on a cylindrical connector piece with rotational mobility. A protrusion on the housing and a recess on the rotatable joint tube engage each other in the locking position and secure the short, rotatable joint tube against rotation. A spring-loaded locking lever is supported on the housing, which, in the locking position, engages a shoulder located on the periphery of the tilting joint piece.

Description

technical field [0001] The present invention relates to a front brush attachment as a cleaning head for a vacuum cleaner. The housing of the suction head has a brush roller chamber which is open on its underside and a suction duct which leads into the brush roller chamber. A rotationally driven brushroll is rotatably supported in the brushroll chamber. A pivoting and oscillating joint connects the vacuum cleaner to the housing. The joint has a pivot joint part which is inserted into the suction channel and a short rotary joint pipe which is connected in a rotational manner to the pivot joint part. When pivoted upward, the swivel and swing joint enters a locked position on a stop surface on the housing. Background technique [0002] The front brush attachment is intended for use with vacuum cleaners that include a fan, a dust bag for holding dirt, and a handle behind it. The vacuum cleaner can be connected to the rotating and oscillating joint of the front brush attachmen...
