摘要： 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.

摘要： The invention relates to a vacuum cleaner nozzle that is provided with a latching device between the attachment stub and the nozzle housing. These elements are latched together in a defined swivelling range in such a way that they perform a common synchronized swivelling movement. The elements can be unlatched again by overcoming the action of a spring-loaded latching bolt.

摘要： The invention is directed to an attachment nozzle for a vacuum cleaning system such as a vacuum cleaner or the like which includes a rotating brush. A modular step-up gear transmission is interposed between the brush and the air turbine which runs in the suction air stream. The attachment nozzle includes an outer ring region wherein a plurality of air-inlet apertures are formed which are covered either partially or entirely by means of a ring-shaped body which is rotatably mounted on the end portion of the housing. A cup-shaped recess is formed centrally of the plurality of air inlet openings and defines a cup-shaped recess for receiving the modular gear transmission therein.

摘要： The invention relates to an apparatus for performing work on a floor surface such as an electrically driven vacuum and polishing machine. The machine includes a chassis and a wand pivotally connected to the chassis by a pivot connection. A vacuum cleaner suction unit is mounted on the wand and the weight force of the suction unit acts outside of the center of gravity conjointly defined by the chassis and the floor working device mounted on the chassis. The floor working device acts on the floor surface with an uneven force distribution. A spring coacts with the pivot connection to shift at least a portion of the weight force of the suction unit to the center of gravity of both the chassis and the floor working device to provide a more even distribution of the force acting on the floor surface.

摘要： A connecting element for connecting an accessory instrument to a vacuum cleaner, has a front portion having a central axis and being tiltably connectable with an accessory instrument, a connecting portion having a further central axis and connectable with a vacuum cleaner as well as rotatably connected with the front portion, and a rotary joint which rotatably connects the connecting portion with the front portion. The rotary joint is arranged so that in normal position of the front and connecting portions, their central axes extend rectinlinearly in one direction, whereas in a plurality of further positions the central axes of these portions extend at an angle relative to one another. Advantageously, this angle is equal to between 10.degree. and 20.degree..

摘要： The invention relates to an electric vacuum cleaner having a filter bag intermediate carrier disposed between a filter cassette arranged above a motor-driven blower and the motor housing. The intermediate carrier is pivotally mounted via a hinge and has guide cams which dip into engaging recesses of a base plate of the filter bag. The vacuum cleaner apparatus can only be operated with filter bags which are specific to this apparatus. Safety cams are formed on the intermediate carrier and follow the inner wall surface of the filter cassette when the intermediate carrier is closed. Catches are formed on the inner wall surface but do not catch the safety cams if an authorized filter bag is placed in the filter cassette. However, if an unauthorized filter bag is placed in the filter cassette, then the structure of this filter bag causes the safety cams to deflect and catch in the catches thereby preventing the operator from completely closing the intermediate carrier on the filter cassette.
摘要翻译：本发明涉及一种电动吸尘器，该电动吸尘器具有设置在电动鼓风机上方的过滤器盒和电动机壳体之间的过滤袋中间载体。中间托架通过铰链枢转地安装，并且具有引入凸轮，该引导凸轮浸入过滤袋底座的接合凹槽中。吸尘器设备只能用特定于该设备的过滤袋进行操作。当中间载体关闭时，安全凸轮形成在中间载体上并且跟随过滤器盒的内壁表面。在内壁表面上形成卡扣，但如果将过滤袋放置在过滤器盒中，则不会抓住安全凸轮。然而，如果将未经许可的过滤袋放置在过滤器盒中，则该过滤袋的结构使得安全凸轮偏转并卡在卡子中，从而防止操作者完全关闭过滤器盒上的中间载体。
