Definitions

  • the present invention relates to a holding plate for a vacuum cleaner bag according to the preamble of claim 1 and a guide device for a vacuum cleaner with a vacuum cleaner bag.
  • the DE 102 03 460 A1 discloses a vacuum cleaner bag with a holding plate which can be pushed into a guide device of a vacuum cleaner.
  • a displaceable closure element is provided on the holding plate, by means of which an inflow opening can be covered.
  • the vacuum cleaner bag is fixed to the guide device of the vacuum cleaner via the holding plate, two opposite edges being pushed into a guide of a vacuum cleaner to position the holding plate.
  • the holding plate is made comparatively long and is held in the guide of the vacuum cleaner with play. As a result, the positioning of the holding plate is not particularly exact.
  • the DE 10 2007 053 151 A1 discloses a holding plate for a vacuum cleaner bag, in which an inflow opening is formed in the holding plate and can be closed via an integrally formed pivotable flap.
  • the flap can be inserted in a trough-shaped receptacle of the holding plate.
  • the holding plate is designed to be comparatively long in the insertion direction in order to be guided with play in a guide device of a vacuum cleaner, the accuracy of the positioning being limited and, moreover, the use of material for the holding plate being high.
  • US 2007/0214755 A1 discloses a vacuum cleaner bag with a holding plate on which a closure plate is slidably mounted. As a result, an inflow opening can be opened or closed via the closure plate.
  • a bendable web is provided on at least one side of a base plate, which web forms a sliding surface when a guide is moved.
  • the holding plate can be positioned exactly within a guide device of a vacuum cleaner in that the at least one flexible web forms a sliding surface and is supported on the guide.
  • This enables play-free, but smooth guidance of the base plate and exact positioning of the holding plate.
  • the length of the base plate can be made shorter in the direction of insertion, since there is no longer any risk of the base plate tilting in the guide.
  • the at least one flexible web is preferably connected to the base plate at opposite ends.
  • the bendable web has a bridge shape and can be bent in the direction of the base plate, for example by at least 1 mm.
  • a slot-shaped opening, which defines the bending area of the web, can be formed between the base plates and the at least one bendable web.
  • At least one bendable web is provided on opposite sides of the base plate.
  • the base plate can be pretensioned to a central position in the guide device by the flexible webs. It is possible to provide a plurality of bendable webs on each side of the base plate, which can also be arcuate, rod-shaped or have a different geometry. Preferably, however, only a single elongated bendable web is provided, which is connected to the base plate in the form of a bridge at opposite ends.
  • the base plate In the direction of insertion, the base plate preferably has a length that is less than 1.5 times the diameter of the inflow opening. This is shorter than in the case of the holding plates known in the prior art.
  • the base plate is formed by the area of the holding plate which has an essentially rectangular outer contour. Individual elements, such as a protruding arm or a grip section, which are not counted as part of the base plate in the length measurement, can be molded onto this outer contour.
  • the base plate is preferably displaceable on opposite sides in a guide device of a vacuum cleaner. This area of the base plate has, for example, a length in the direction of insertion which is between 0.9 times and 1.2 times the diameter of the inflow opening in the base plate.
  • the closure element is designed as a closure flap which is preferably connected to the base plate at an outer edge of the base plate via at least one film hinge and protrudes therefrom in an open position.
  • the film hinge can for example be arranged in the area of a ring around the inflow opening, two spaced-apart film hinges being formed on the closure flap for a compact structure, between which an arcuate section is formed, into which a ring of the inflow opening can be inserted.
  • closure flap can preferably be locked in a closed position on the base plate.
  • a closure in the sense of the application does not have to be a sealed closure, but can be a covering of an inflow opening which is surrounded by the base plate or a sealing element arranged on the base plate.
  • a vacuum cleaner bag with a holding plate is pushed into the guide device.
  • at least one bendable web rests against the base plate in a clamping manner in the guide device and ensures exact positioning of the base plate and thus also the inflow opening.
  • the guide device can have a groove or a guide channel into which an edge of the base plate with the flexible web is inserted. Grooves or channels of the guide device are preferably provided on opposite sides of the base plates in order to effect a corresponding guide.
  • the guide device preferably has a straight guide section and a curved guide section, the closure flap having a guide element which engages in the curved guide section when it is pushed in.
  • the base plate remains in the straight guide section in the insertion direction and is not bent.
  • the guide device be better adapted to the contour of a vacuum cleaner bag, which usually has a pillow-shaped contour adjacent to the inflow opening, especially if the vacuum cleaner bag is designed as a flat bag in which two rectangular bag walls are connected to one another at the edge.
  • the guide element can be designed as a web which protrudes essentially parallel to the axis of rotation of the closing flap.
  • a bracket can optionally be formed on the base plate in the insertion direction, in particular a rigid, dimensionally stable bracket which forms a stop for limiting the depth of insertion into the guide device.
  • a corresponding stop can also be provided at a different position on the base plate or the closure flap instead of on the boom.
  • a holding plate 1 for a vacuum cleaner bag (not shown) comprises a base plate 2 which has an essentially rectangular outer contour.
  • An inflow opening 3 is formed in the base plate 2, into which a nozzle of a vacuum cleaner can be inserted.
  • An elastic sealing element can be attached to the base plate 2 around the inflow opening 3, or the filter material of the vacuum cleaner bag protrudes in a ring shape into the inflow opening 3 and thus forms the opening into which the nozzle of the vacuum cleaner is inserted positively or non-positively.
  • the inflow opening 3 of the base plate 2 can thus be made larger than an inflow opening in the filter material of the vacuum cleaner bag or an annular sealing element on the inflow opening 3.
  • a closure flap 4 which is formed integrally and is connected to the base plate 2 via two spaced film hinges 5, is articulated on the base plate 2.
  • the closure flap 4 can be of the in the Figures 1A and 1B
  • the opening position shown can be pivoted by approximately 180 ° into a closing position in order to essentially cover the inflow opening 3 and thereby close it.
  • the closing flap 4 covers at least the opening area within a sealing ring or the opening in the filter material in the closed position.
  • an arcuate area 7 is formed on the closure flap 4, which area surrounds a ring 6 around the inflow opening 3.
  • the axis of rotation of the closure flap 4 can be arranged in the area of the ring 6 around the inflow opening 3.
  • the filter material of a vacuum cleaner bag can be fixed to the ring 6, for example by welding or gluing.
  • the vacuum cleaner bag can be designed as a flat bag or a block-bottom bag, in particular made from a single-layer or multi-layer non-woven fabric or another filter material.
  • a laterally protruding guide element 8 is formed on the closure flap 4, which protrudes in a web-like manner parallel to the axis of rotation of the closure flap 4 and can engage in a guide device of a vacuum cleaner.
  • the latching receptacle 10 can be designed as a recess or receptacle and have a holding element on which the guide element 8 can be latched.
  • the closing flap 4 On the side opposite the film hinge 5, the closing flap 4 has a tip 11 with a step-like design, which in a closed position can be placed in a form-fitting manner on the edge around the inflow opening 3.
  • a narrow web-shaped bracket 12 is also formed, which extends parallel to the plane of the base plate and the closure flap 4 in the Figures 1A and 1B extends and has almost the same length as the closure flap 4.
  • the boom 12 forms a stop to limit the insertion depth.
  • the base plate 2 without the arm is short in the insertion direction, for example with a length between 1 and 1.2 times the diameter of the inflow opening 3.
  • a bendable web 14 is formed on opposite sides of the base plate 2 and is connected to the base plate 2 at opposite ends.
  • the bendable web 14 is thus designed in the shape of a bridge and is spaced apart from the base plate 2 via a slot-shaped opening 15 in a central region.
  • the slot-shaped opening 15 enables a bending movement of the web 14, which can be, for example, between 1 mm and 3 mm perpendicular to the direction of insertion.
  • the bendable web 14 extends by at least 50% of the length of the base plate 2 in the direction of insertion, preferably between 60% and 90% of the length.
  • the base plate 2 On the side opposite to the closure flap 4, the base plate 2 has a protruding grip section 13, on which the base plate 2 can be gripped when being pushed in and pulled out of a guide device.
  • the handle section 13 protrudes over an edge of the base plate 2 and thus does not contribute to the length of the handle base plate 2 in the insertion direction.
  • ribs 16 are also provided on a side facing the vacuum cleaner bag, which can be inserted into elongated receptacles 17 of an adjacent base plate 2 so that the holding plate 1 can be better stacked when the vacuum cleaner bags are assembled.
  • the elongated receptacles 17 serve to receive the ribs 16 on the opposite side of the base plate 2 in a form-fitting manner.
  • the holding plate 1 is shown in a guide device 30 of a vacuum cleaner without the other components of the vacuum cleaner and the filter bag of the vacuum cleaner bag.
  • the guide device 30 comprises on opposite sides a groove with a straight guide section 31 and an adjoining curved or angled guide section 33.
  • the base plate 2 is positioned on the straight guide section 31, with a web 32 protruding towards the base plate 2 being formed on one groove wall, which tapers the groove and holds the base plate 2 essentially positively in an operating position.
  • the straight guide section is followed by the curved guide section 33, which protrudes at an angle from the plane of the base plate 2 and opens into a pocket 34 which, for example, at an angle between 20 ° to 80 °, in particular 30 ° to 70 °, to the plane of the Base plate 2 is aligned.
  • the closing flap 4 When inserting the retaining plate 1, the closing flap 4 is arranged at the front.
  • the closure flap 4 When the retaining plate 1 is pushed into the guide device 30, the closure flap 4 initially remains in the plane of the base plate 2 until the laterally protruding guide element on the closure flap 4 reaches the curved guide section 33. Then, via the guide element 8, which slides in the curved guide section 33, the closure flap 4 is pivoted about the film hinge 5 until the holding plate 1 is arranged in an end position.
  • the end position can be specified, for example, via the boom 12, which represents a stop that interacts with a counter-stop on the vacuum cleaner.
  • the closure flap 4 is pivoted by being pushed into the guide device 30, preferably by an angle of more than 10 °, preferably between 20 ° and 60 °. In the pushed-in position, the space requirement of the holding plate 1 is reduced, since the closure flap 4 is adapted to the geometry of the vacuum cleaner bag.
  • the vacuum cleaner preferably has a detection device by means of which it can be detected whether a vacuum cleaner bag with a holding plate has been inserted into the guide device.
  • This detection device can for example be done mechanically and actuated by the boom 12 or the closure flap 4 so that the vacuum cleaner knows whether a vacuum cleaner bag has been inserted or not, which can trigger a lock-in blockage or some other measure on the vacuum cleaner, for example.
  • the holding plate 1 can be pulled out again by pulling on the handle section 13, the closing flap 4 being aligned again parallel to the base plate 2 by the guide on the curved guide section 33 and then being manually folded over into the closing position by the user .
  • the pivotability of the closure flap 4 is easy, since the film hinges 5 have already been moved.
  • the closure flap is pivotably mounted on the base plate. It is of course also possible to provide a closure element such that it can be displaced on the base plate 2 for example in the DE 102 03 460 A1 is shown.
  • the closure element can be formed integrally with the base plate 2 via several pivotable lamellae, but a separate formation of the closure flap or closure element relative to the base plate 2 is also possible.
  • the closure flap can also be displaceably mounted on the base plate 2 by means of corresponding guide strips, instead of the film hinges 5 shown.
  • the vacuum cleaner bag fixed to the base plate 2 can be made from a filter material as a flat bag, block bottom bag or other bag.
  • the filter bag is preferably welded to the base plate 2.
  • a bendable bridge-shaped web 14 is formed on each side of the base plate 2. It is of course also possible to provide more than just one bendable web on one side. In addition, the webs can also have a different shape and only be connected to the base plate 2 on one side.
  • the holding plate 1 can be produced as a one-piece component made of plastic.
