Definitions

  • the present invention relates to a guide device of a vacuum cleaner with a vacuum cleaner bag, wherein the vacuum cleaner bag is fixed to a support plate having a base plate on which an inflow opening is formed, wherein on the base plate a closure flap is pivotally mounted, by means of which the inflow opening is closable, a holding plate for a vacuum cleaner bag and a method for positioning a vacuum cleaner bag with a holding plate in a vacuum cleaner.
  • the DE 102 03 460 A1 discloses a vacuum cleaner bag with a holding plate, which is inserted into a guide device of a vacuum cleaner. On the holding plate, a displaceable closure element is provided, by means of which an inflow opening can be covered on the holding plate.
  • the vacuum cleaner bag is fixed by the holding plate on the guide device of the vacuum cleaner by inserting.
  • the retaining plate is comparatively long and is held with play in the leadership of the vacuum cleaner. As a result, the positioning of the holding plate is not very accurate and the holding plate requires a comparatively large amount of space.
  • the DE 10 2007 053 151 A1 discloses a retaining plate for a vacuum cleaner bag, wherein in the holding plate, an inflow opening is formed, which is closable via an integrally formed pivotable flap.
  • the flap can be inserted in a trough-shaped receptacle of the holding plate.
  • At least one projecting guide element which can be inserted into a guide device of a vacuum cleaner, is formed on the holding flap on a holding plate which has a base plate and a pivotable closing flap.
  • the closure flap can be pivoted relative to the base plate, which, in the installation situation, makes possible an angular alignment of the closure flap relative to the base plate.
  • the required installation volume for the retaining plate is reduced because the closure flap adapts better to the contour of the adjacently arranged vacuum cleaner bag.
  • the handling of the flap is improved because it is pivoted after manufacture at least twice by inserting and pulling out of the guide device, so that it can then be easily operated by the user.
  • the guide device has a straight and a curved guide portion.
  • the guide element on the closure flap is preferably inserted in the mounted position in the bent guide portion, so that the closure flap is pivoted during insertion relative to the base plate.
  • the base plate is inserted only in the straight guide section, so that a smooth shifting is possible.
  • the guide element may be formed as a web which extends substantially parallel to a rotational axis of the closure flap.
  • the guide element can protrude on one side or on both sides of the closure flap, for a material-saving construction, the guide element can preferably be provided only on one side of the closure flap.
  • the base plate in the insertion direction has a small length, in particular a length which is smaller than 1.5 times the diameter of the inflow opening.
  • the length of the base plate in the insertion direction may be between 0.9 times to 1.2 times the diameter of the inflow opening in the base plate.
  • the bendable web can be designed as a bridge web, which is connected at opposite ends to the base plate.
  • a slot-shaped opening can be formed between the bendable web and the base plate, which gives the bendable web a freedom of movement perpendicular to the direction of insertion, which, for example, can be between 1 mm and 3 mm.
  • the vacuum cleaner bag with the holding plate is first inserted into a guide device of the vacuum cleaner, wherein a closing flap pivotably mounted on a base plate is arranged in the front insertion direction.
  • the closure flap is simultaneously pivoted about an axis of rotation relative to the base plate, wherein the closure flap is guided with a guide element in the guide device.
  • the guide device preferably has a straight guide section and a curved guide section.
  • the base plate is inserted only in the straight guide portion, while the guide member is pushed on the closure flap first by the straight guide portion and then in the bent guide portion to effect pivoting relative to the base plate.
  • the vacuum cleaner preferably has a detection device, by means of which it is possible to detect whether a vacuum cleaner bag with a retaining plate has been inserted into the guiding device, wherein the closing flap switches the detecting device on insertion.
  • the closure flap can optionally be locked in the inserted position on the guide device.
  • a holding plate 1 for a vacuum cleaner bag comprises a base plate 2, which has a substantially rectangular outer contour.
  • an inflow opening 3 is formed, into which a nozzle of a vacuum cleaner can be inserted.
  • an elastic sealing element, or the filter material of the vacuum cleaner bag projects annularly into the inflow opening 3 and thus forms the opening into which the neck 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 third
  • a closure flap 4 is articulated, which is integrally formed with the base plate and is connected via two spaced film hinges 5 to the base plate 2.
  • the flap 4 can from the in the Figures 1A and 1B shown opening position to be pivoted by about 180 ° in a closed position to substantially cover the inflow opening 3 and thereby to close.
  • the closure 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 region 7 is formed on the closure flap 4, which surrounds a ring 6 around the inflow opening 3.
  • the axis of rotation of the closure flap 4 in the region of the ring 6 can be arranged around the inflow opening 3.
  • the filter material of a vacuum cleaner bag can be fixed, for example by welding or gluing.
  • the vacuum cleaner bag may be formed as a flat bag or block bottom bag, in particular of a single or multi-layer nonwoven fabric or another filter material.
  • a laterally projecting guide element 8 is formed, which protrudes in the manner of a web parallel to the axis of rotation of the closure flap 4 and can engage in a guide device of a vacuum cleaner.
  • a latching web 9 On the guide element 8 is a latching web 9, which can be latched to a locking receptacle 10 of the base plate 2.
  • the locking receptacle 10 may be formed as a recess or receptacle and have a holding element on which the guide element 8 can be latched.
  • the closure flap 4 has, on the side opposite the film hinges 5, a point 11 with a step-shaped formation which can be placed in a closed position in a form-locking manner against the edge around the inflow opening 3.
  • a narrow web-shaped arm 12 is further formed, which is parallel to the plane of the base plate and the flap 4 in the Figures 1A and 1B extends and has almost the same length as the flap 4.
  • the boom 12 forms a stop for limiting the insertion depth.
  • the base plate 2 without the boom 12 is short in the insertion direction, for example, with a length between 1 and 1.2 times the diameter of the inflow opening third
  • a bendable web 14 is formed, which is connected at opposite ends to the base plate 2.
  • the bendable web 14 is thus designed bridge-shaped and spaced from a slot-shaped opening 15 in a central region of the base plate 2.
  • the slot-shaped opening 15 allows a bending movement of the web 14, which may be for example between 1 mm and 3 mm perpendicular to the insertion direction.
  • the bendable web 14 extends in this case by at least 50% of the length of the base plate 2 in the insertion direction, preferably between 60% and 90% of the length.
  • the base plate 2 On the opposite side to the flap 4, the base plate 2 has a protruding handle portion 13, on which the base plate 2 can be gripped during insertion and withdrawal from a guide device.
  • the handle portion 13 protrudes beyond an edge of the base plate 2 and can be disregarded due to the narrow configuration in the determination of the length of the base plate 2 in the insertion direction.
  • ribs 16 are further provided on a side facing the vacuum cleaner bag side, which are inserted into elongated receptacles 17 of an adjacent base plate 2, so that the holding plate 1 is better stackable in the packaging of the vacuum cleaner bag.
  • the elongate receptacles 17 serve for the form-fitting reception of the ribs 16 on the opposite side of the base plate 2.
  • FIG. 2 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 or a channel with a straight guide portion 31 and an adjoining curved or angled guide portion 33.
  • the base plate 2 is positioned, wherein on a groove wall to the base plate 2 projecting web 32nd is formed, which tapers the groove and the base plate 2 holds substantially form-fitting in an operating position.
  • the straight guide section 31 is adjoined 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.
  • the bent or angled guide portion 33 is aligned, for example, at an angle between 20 ° to 80 °, in particular 30 ° to 70 °, to the plane of the base plate 2.
  • the flap 4 When inserting the holding plate 1, the flap 4 is arranged at the front.
  • the closure flap 4 When inserting the holding plate 1 into the guide device 30, the closure flap 4 initially remains in the plane of the base plate 2 until the laterally projecting guide element on the closure flap 4 reaches the curved guide section 33. Then, via the guide member 8, which slides in the curved guide portion 33, a pivoting of the closure flap 4 is effected about the film hinges 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 which cooperates with a counter-stop on the vacuum cleaner.
  • any stop to limit the insertion depth may also be provided at a different position.
  • the closure flap 4 is pivoted by insertion into the guide device 30, preferably at an angle of more than 10 °, preferably between 20 ° and 60 °. In the retracted position is the Space requirement of the holding plate 1 is reduced because the 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 has been inserted with a holding plate in the guide device.
  • This detection device can for example be made 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, for example, a Einperrblockade or other measure on the vacuum cleaner.
  • the holding plate 1 When the vacuum cleaner bag is filled, the holding plate 1 can be pulled out by pulling on the handle portion 13, wherein the shutter 4 is aligned by the guide on the curved guide portion 33 again parallel to the base plate 2 and then manually can be folded by the user in the closed position ,
