Definitions

  • the invention relates to a Upright-type vacuum cleaner with an upper body with dust collection container, and with a bottom unit, which is movable by a chassis on the surface to be cleaned, wherein between the upper body and bottom unit a tilting joint is arranged, through which the upper body in use relative to Ground unit is mounted pivotably about a horizontal axis from an at least approximately vertical parking position in an obliquely tilted working position and wherein between the upper body and bottom unit, a rotary joint is arranged, which allows a change in direction of the moving ground unit by rotating the upper body.
  • 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, see for example the US Pat. No. 3,932,912 or the US 4 423 534 A , In this fixed with respect to the tilting position of the upright is then automatically. During the suction process, this lock is released and the upper body tilted at 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.
  • Such an upright is for example from the WO 2007/008770 A2
  • a disadvantage of the Upright according to WO 2007/008770 A2 is that it is difficult to move from a straight direction in curved paths.
  • From the EP 0 708 613 A1 It is known to provide a fulcrum between the upper body and the upper portion of the fan. This achieves improved maneuverability because the upright is now able to perform cornering. If the upper body is then rotated in the parking position, there is a risk that the center of gravity of the Uprights is shifted out of its footprint and the device consequently tilts.
  • the EP 1 647 219 A2 discloses a suction attachment, wherein in the region of the coupling piece to a suction pipe, a combined Drehkippgelenk is arranged. This joint can be manually locked in a certain standing position both with respect to the tilting movement as well as with respect to the rotational movement.
  • the invention thus raises the problem of increasing the stability in a vacuum cleaner of the type mentioned.
  • the rotary locking device comprises a first spring-mounted bolt, which engages in the parking position in a bore.
  • a first spring-mounted bolt which engages in the parking position in a bore.
  • the means may expediently comprise a Auffahrschräge and a second, resiliently mounted on the first bolt bolts.
  • the first bolt is mounted on a fork-shaped component, which is a pivotable component of the tilting joint and fixed part of the rotary joint.
  • the rotary locking device comprises a locking pin, which cooperates with a substantially V-shaped guide, wherein the guide locks the bolt in a first pivot position and releases upon movement of the upper body of the pivoting position.
  • Upright vacuum cleaner shown in various views, hereinafter referred to as Upright 1, consists essentially of a bottom unit 2, an upper body 3 and a joint arranged therebetween, which will be described later.
  • the upright 1 can from an upright 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 extended 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 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.
  • the corresponding joint is referred to in the text as a hinge.
  • the ground unit 2 in FIG. 7 shown in exploded view, comprises a housing, which is formed by a housing insert 5, a rear housing lower part 6, a front housing lower part 7, a bumper strip 8 and a cover part 9.

  • the locking pin 201 moves into the effective range of a V-shaped guide 202, which is arranged on the housing insert.
  • a rotational movement of the upper body 3 is then no longer possible.
  • tilting the upper body 3 in the working position of the pin 201 moves from the top 203 in the widened portion 204 of the guide 203, where the lock is released and rotation is possible again.
  • This variant of the rotary lock has the advantage that the pin 201 centered in the guide 202 itself. A state in which the upper body 3 is rotated rotated in the parking position (see FIG. 9c ), is not possible here. However, there is the disadvantage that the entire pivoting range between pin 201 and guide 202 may not lie in the pivoting path of the fork 40. For this reason, a modified fork would be required, which requires much more space.
