Definitions
- the invention relates to a filter bag for a vacuum cleaner, with one of several dimensionally stable layers formed holding plate with a flow opening is provided, with a deviating from the circular shape in a middle position Breakthrough is provided in which a through-opening and closing slide is movably guided.
- the filter bag in question is made of an air-permeable material.
- the holding plate To hold it in the vacuum cleaner housing, the holding plate must be dimensionally stable. she usually consists of three layers, which are made of cardboard and if necessary still from an intermediate between an outer and the middle layer Sealing washer made of a flexible material. Usually the middle layer made of cardboard with an opening that differs from the circular shape, in which a slide is guided.
- the opening is in a filter bag known from DE 94 19 171 U1 arcuate in such a way that a corresponding, with a flow opening provided slide can be pivoted about a fixed axis.
- the slide can only be used with a relatively large amount of force be rotated because it is due to unavoidable manufacturing tolerances jamming.
- the slide is closed with two fingers twist, which are placed from both sides on the pivot point of the axis.
- the present invention has for its object a filter bag of the beginning mentioned type in a simple manner so that the movement of the Slider can be done with less effort.
- the slide as a linear slide is formed by means of a non-connected, but positive pivoting lever engaging therein from a through-flow opening releasing open position in a closed position covering the flow opening is movable.
- one of the in the open position of the linear slide abutting edges of the linear slide and the opening has a recess into which a guide lug engages the other edge. This is particularly easy to achieve if the recess in the linear slide and the guide lug on the Breakthrough edge is provided.
- the swivel lever can be designed so that it is used as a support and stop.
- the pivot lever is designed as a flat molded part, which on the the linear slide and the guide lug side or corner into one Contour-appropriate recess of the linear slide engaging round piece is provided is, and that on the opposite, facing the linear slide Side a cut-free web is arranged, the opposite of the round piece Edge of the linear slide hits. This ensures that in the closed position of the linear slide the round piece as a stop and the free cut
- the bridge acts as a support, when moving the linear slide from the closed position in the open position, the web first causes the linear movement.
- the contour-appropriate recess, in which engages the round piece is U-shaped.
- the depth is measured so that the the highest position of the swivel lever, the round piece at the bottom of the recess is applied. So that no additional parts are required for mounting the swivel lever are, it is provided that this on the linear slide away from Side has a curved piece, the center of which is the axis of rotation of the pivot lever forms and that the opening for the storage of the pivot lever a correct position Has recess in which the arc piece engages.
- the axis of rotation in one based on the Width of the pivot lever less offset to the opposite web stands, with the offset in the direction of the round piece.
- the holding plate 10 consists of two outer, layers 11, 12 made of cardboard, a middle layer 13, a linear slide 14, a pivot lever 15 and a sealing layer 16.
- the layers 11 to 13 are connected to each other in a manner not shown by gluing.
- the two outer layers 11, 12, the middle layer 13, the linear slide 14 and the sealing layer is provided with circular holes that are aligned with each other are arranged so that a flow opening in the open position of the linear slide 14 17 arises.
- the diameter in the bore of the sealing layer 16 is smaller than that in the other layers, so that in the finished holding plate 10 an in the flow opening 17 protruding sealing ring 18 is formed.
- the middle Layer 13 is provided with an opening 19 deviating from the circular shape, in which the linear slide 14 and the pivot lever 15 are inserted.
- the Linear slide 14 is square in its basic contour, which in the illustration upper left corner runs in an arc.
- the linear slide 14 in the open position Contacting transverse edge is provided with a guide lug 20 which in the open position of the linear slide 14 in an appropriately designed opening 21 engages.
- the pivot lever 15 is on the opening 21 facing Side provided with a round piece 22, which in a U-shaped recess 23 of the linear slide 14 engages.
- the linear slide 14 is on the Round piece 22 opposite side provided with a cut-free web 24, the one in the open position of the linear slide 14 against a cutout formed edge 25 strikes.
- the bow piece 26 is with a circular cutout so that it can be used to pivot the swivel lever 15 is gripping. So that the bow piece 26 clamped between two fingers can be, the two outer layers 11, 12 are with two corresponding Bores 28 provided.
- the between the recess 27 and the guide lug 20 extending surface 19a of the opening 19 is designed as an inclined surface, which rises towards the guide lug 20.
- Figures 2 and 3 show that in the closed position of the linear slide 14 according to FIG. 2, the linear slide 14 through the guide lug 20 and the web 24 are held in position. If the pivot lever 15 in Swiveled clockwise into the open position according to Figure 3, the Thrust movement initially only through the web 24. From a certain Position is then the pushing movement through the round piece 22, which is in the recess 23 rolls. When the round piece 22 reaches the highest position has, it lies on the edge forming the base of the recess 23. At the in 1 to 3 shown embodiment consists of the holding plate 10 three individual layers 11 to 13.
