Abstract:
1. A vacuum cleaner comprising: a vacuum cleaner housing that defines a bag-receiving chamber therein and that has a plurality of individual bag-positioning receivers fixed in said vacuum cleaner housing; a bag-securing element connected to said vacuum cleaner housing; a housing cover movably arranged relative to said vacuum cleaner housing to be selectively movable between a closed position and an open position to respectively close and open said bag-receiving chamber; a filling pipe stub arranged on said housing cover and having a pipe stub end facing into said bag-receiving chamber; and is a filter bag arrangement that is removably received in said bag-receiving chamber; wherein: said filter bag arrangement includes a filter bag body and a filter mounting plate connected to said filter bag body, wherein said filter mounting plate has an inlet opening communicating into said filter bag body, and said filter bag arrangement further includes a latching strap that is permanently connected to and protrudes from said filter mounting plate radially outwardly relative to said inlet opening and that is flexible or is flexibly connected to said filter mounting plate or is pivotably connected to said filter mounting plate, and wherein said latching strap is configured, positioned and arranged to be flexibly deflectable or pivotable toward and into secure engagement with said bag-securing element; said filter mounting plate, at a perimeter thereof, includes at least three individual protruding mounting elements that are configured, positioned and arranged to be respectively inserted and engaged stationarily into said individual bag-positioning receivers fixed in said vacuum cleaner housing in an insertion direction corresponding to a direction in which said filter bag arrangement is inserted into said bag-receiving chamber, wherein said insertion direction is perpendicular to a plane of said filter mounting plate; said mounting elements respectively engaged stationarily in said bag-positioning receivers fixedly spatially position said inlet opening of said filter bag arrangement within said bag-receiving chamber; said filling pipe stub is inserted in said insertion direction and communicates into said inlet opening of said filter bag arrangement at least when said housing cover is in said closed position; said latching strap of said filter bag arrangement, proximate to a free end thereof, includes a latching element; said bag-securing element of said vacuum cleaner includes an opening, a recess, a notch, a groove, a rim, or a lip with which said latching element engages to achieve said secure engagement of said latching strap with said bag-securing element; said housing cover and said latching strap are configured and positioned so that an edge rim portion of said housing cover presses against and thereby flexibly deflects and/or pivots said latching strap toward and into said secure engagement with said bag-securing element as said housing cover is closed to said closed position; said bag-securing element is flexible and/or is pivotably connected to said vacuum cleaner housing; said bag-securing element and said latching strap are configured and positioned so that said bag-securing element is flexibly or pivotally deflected from a first position to a second position by said latching strap being squeezed between said edge rim portion of said housing cover and said bag-securing element and thereby said latching strap bears against said bag-securing element as said housing cover is closed to said closed position: and said bag-securing element in said first position blocks and prevents said housing cover from being closed to said closed position, and said bag-securing element must be is deflected from said first position to said second position by said latching strap squeezed between said edge rim portion of said housing cover and said bag-securing element to enable said housing cover to be closed to said closed position so that said housing cover cannot be closed to said closed position if said latching strap is not present or is not properly positioned between said edge rim portion of said housing cover and said bag-securing element.
