Definitions

  • the invention relates to a vacuum cleaner Upright type according to the preamble of claim 1.
  • the following describes three types of vacuum cleaner that differ in their construction and operation. As common features all have a motor-driven blower, a dust collection room and one or more adapted to the particular purpose tillage equipment.
  • the vacuum cleaner has a housing which is movable on rollers and / or skids on the ground to be processed.
  • the engine fan and the dust collector are arranged in the housing.
  • the soil treatment device - here called floor nozzle - is connected via a suction hose, possibly with an intermediate suction pipe, with the dust collection chamber.
  • the housing is brought into the desired position during the suction process by pulling on the suction tube.
  • the motor fan and the dust collector are also arranged in a housing. From the housing extends on one side of a suction pipe, which connects a floor nozzle with the dust collector, and on the other hand, a handle with which the housing is maneuvered into the desired position.
  • An essential feature of an upright is a movable floor unit, which carries a torso with a large dust collector.
  • the two parts are pivotally mounted to each other and usually fixable in a parking position in which the upper body is approximately vertical when the ground unit is in the use position on a horizontal ground. In this position, the upright is automatic.
  • this locking is released and tilted the upper body by a certain angle in a working position.
  • the swivel angle depends on the one hand on the size of the user and on the other hand from the respective use.
  • a handle on the upper body is used to guide the entire device.
  • the engine fan can be arranged in different places be.
  • a vacuum cleaner Upright type with the features of the preamble of claim 1 known.
  • a cover is arranged as a fixed part of the ground unit in the joint area. Although the cover hides the interior of the ground unit even when swiveling the upper body, but this creates a gap between the upper body and cover especially at a larger pivot angle. This can lead to pinching of fingers.
  • the invention thus raises the problem of avoiding the emergence of open spaces by relative movements between the upper body and ground unit in a vacuum cleaner of the type mentioned.
  • a front cover can cover a free space in the upper area of the floor unit.
  • This front cover should then suitably a front Aperture be assigned, which is slidably mounted in a guide on the ground unit.
  • the means that automatically move the front panel to an extended position may be readily formed as cooperating hook members on the front panel and on the front panel.
  • the stop, which pushes the front panel in the retracted position, can be formed by a component of the tilting joint.
  • a rear cover can cover a free space in the lower area of the floor unit.
  • the rear cover should have at least one cutout, which prevents a contact with at least one wheel arranged on the ground unit during a pivoting movement, in which a gap in the lower region of the ground unit is reduced.
  • a rear panel is provided in an advantageous manner, which disguises the cutout in a pivotal movement increasing the gap in the lower region of the ground unit. This can be slidingly mounted on the rear cover.
  • the means which automatically move the rear panel to an extended position may be formed as cooperating hook members on the rear panel and on a lower housing portion. It is also useful if the stop, which pushes the rear panel in the retracted position, is arranged on the housing base. It should be dimensioned so that it prevents contact of the panel with the wheel.
  • the covers are arranged on a fork-shaped channel component, which is part of the tilting joint.
  • Upright vacuum cleaner shown in different views, hereinafter referred to briefly as Upright 1, consists essentially of a ground unit 2, an upper body 3 and a joint arranged therebetween, which is described later.
  • the Upright 1 can from an upright parking position (see FIGS. 1 to 3 ), in which he is latched and then stands free, after releasing the locking (see FIG. 7 ) into a tilted ( FIGS. 4 and 5 ) and even in a fully stretched working position ( FIG. 6 ) to be brought.
  • ground unit 2 and upper body 3 are a horizontal axis X in use (see FIG FIG. 5 ) mounted to each other pivotally.
  • the joint which allows the pivoting movement, is referred to below as a tilting joint.
  • the upright in the tilted working position, as well as in FIG. 5 shown rotated about an axis Y. By rotating the upper body 3 by means of the appliance handle 4 about this axis and simultaneously pushing or pulling the upright, the user can control the floor unit 2 around curves.
