The invention is directed to a telescopic guide wand for floor-cleaning apparatus such as household vacuum cleaners. The guide wand includes two concentrically arranged tubes which telescopically engage each other and conjointly define an inner space to accommodate the electrical supply cable for the motor blower head of the vacuum cleaner. The tubes are latched with respect to each other in several steps and the supply cable extends as helically configured cable within the upper portion of the wand. The supply cord extends concentrically out of the end of the upper tube which is configured as a handle and can be connected to the house electrical supply system. The end of the guide wand facing toward the apparatus has a connecting device disposed thereon. On its upper member, the guide wand has the following: a stowing cavity for the cable lined with insulating material; a guide sleeve minimizing the telescoped overall length of the wand which supports, when the wand is in its extended position, the portion facing the motor; and, an end stop to prevent separation of the upper and lower members.

Telescopic guide wand for floor-cleaning appliances

An electric vacuum cleaner having a chamber arranged above the motor housing to receive a filter bag the side of which facing the motor housing is in valve-closed socket-connection communication with the fan-air channel and which can be removed from the chamber after opening and separating the socket connection. The filter bag is in socket-connection communication with a filter-bag intermediate support which is carried along upon the swinging open of the chamber and which has the valve-closure member and from which the filter bag can be separated somewhat on the other side of the vertical position of the cross-sectional plane of the socket connection.

A floorcare device has a round brush located in a housing and rotatable about a rigid axle. At least one axial end portion of the axle is supported in the housing by an eccentric, so that by turning the eccentric the height of the axle and thereby of the round brush relative to the housing can be varied. Turning of the eccentric is performed by a ratchet mechanism. Another such eccentric may support the other end of the axle. The ratchet mechanism may include two ratchet wheels each provided on a respective one of the eccentrics, and two rings surrounding the ratchet wheels and having inner ratchets engageable with the latter.
