Description

The present invention relates to an adapter device for attaching a vacuum cleaner bag to a vacuum cleaner-specific holding plate, which is provided for receiving in a vacuum cleaner bag holder of a vacuum cleaner adapted to this holding plate and having a Halteplattendurchgangsbohrung, with a base member having a first surface and a second surface and a through hole extending between the first and second surfaces. Another aspect of the present invention relates to a vacuum cleaner bag having a bag portion provided for storing dust and dirt in its interior and having an opening, and a terminal portion. A third aspect of the present invention relates to a method for connecting an adapter device for a vacuum cleaner bag with a vacuum cleaner-specific holding plate, which is provided for receiving in a vacuum cleaner bag holding device of a vacuum cleaner adapted to this holding plate.

Vacuum cleaner bags usually have a holding plate provided with a holding plate through-hole and fixed to the bag section in a manner such that the holding plate through-hole is overlapped with the opening of the bag section and the holding plate through-hole has access to the bag section Interior of the bag section represents. In other words, the holding plate through-hole is the inflow opening of the vacuum cleaner bag. The edge region of the holding plate is partially or completely spaced from the actual bag, so that the holding plate is inserted into a suitably shaped vacuum cleaner bag holding device of a vacuum cleaner and in this releasably in a predetermined Position can be secured by appropriate means of the vacuum cleaner bag holding device on the holding plate and in particular attack on its spaced from the bag portion edge region. For example, such a vacuum cleaner bag holding device may have a rail device into which the holding plate can be inserted. The holding plates are typically flat, ie not curved.

In this context, each manufacturer of vacuum cleaners and vacuum cleaner bags usually provides that the vacuum cleaner bags of other manufacturers can not be used with their own vacuum cleaners, and also regularly that not all of their own vacuum cleaner models with the same type of vacuum cleaner bags are usable. Rather, the user of a vacuum cleaner must always purchase vacuum cleaner bags of the type that fits the manufacturer and model of each vacuum cleaner. In order to make the vacuum cleaner bags in this way device or model specific, are on the one hand vacuum cleaner bags of different types equipped with different holding plates, for example, in their dimensions, shapes and / or positions and dimensions of the inflow opening forming Halteplattendurchgangsbohrung from each other distinguished, and on the other hand in the respectively associated vacuum cleaners, the vacuum cleaner bag holding device designed so that in it substantially only the corresponding holding plate can be fixed in the predetermined position. Thus, many vacuum cleaners differ in the shape of the vacuum cleaner bag holder, which requires a separate form of vacuum cleaner bag for each of these different vacuum cleaners or vacuum cleaner bag holders. In other words, the holding plates of conventional vacuum cleaner bags are each formed specifically for a particular model of vacuum cleaner or a particular vacuum cleaner model group by In particular, different vacuum cleaner models have differently shaped fasteners for the holding plates and usually the position and the diameter of the inflow opening in the respective holding plates are different. Such holding plates are thus vacuum cleaner-specific holding plates. They are attached to the device-specific vacuum cleaner bag provided by the manufacturer and designed so that they fit into a provided in the vacuum cleaner device-specific holding device.

The need to use device or vacuum cleaner-specific vacuum cleaner bag is not only disadvantageous to consumers who painstakingly choose among a variety of different vacuum cleaner bags suitable for their vacuum cleaner and find a dealer who leads this, but also for Retailers who have to stockpile and offer a very large number of different types of vacuum cleaner bags if you want to reach a large clientele.

Solutions are known from the prior art, which circumvent the problem of the need specifically adapted to the respective vacuum cleaner model vacuum cleaner bag by an adapter device is provided, with the help of a universal vacuum cleaner bag - ie a vacuum cleaner bag, including its usually existing holding plate predetermined shapes and dimensions independent of a particular vacuum cleaner model - can be attached to a vacuum cleaner-specific holding plate, which has previously been replaced by the user of a corresponding vacuum cleaner-specific vacuum cleaner bag. It is known on the one hand to provide a universal vacuum cleaner bag with its own, universal plate and a separate adapter device, which must be connected on the one hand to the mounting plate of the universal vacuum cleaner bag and on the other hand with the vacuum cleaner-specific plate. On the other hand It is also known to provide a universal vacuum cleaner bag with its own, universal plate that must be attached directly by means of an adhesive bond, for example by tape or foil, to the vacuum cleaner-specific plate. In the context of the present application, such, firmly connected to the bag portion of a (universal) vacuum cleaner bag and thus an integral part of this forming holding plate is referred to as an adapter device, since it must be adapted to be connected to different vacuum cleaner-specific holding plates can.

Known adapter devices comprise a plate-shaped or differently shaped base element having a first surface and a second surface and a through-bore extending between the first and the second surface and in use constitutes a part of the inflow opening in the vacuum cleaner bag. The base member is either fixedly connected to a bag section at its second surface by suitable means or may be releasably connected to a bag section by suitable means. In a fixed connection, the base member in the connected state, the holding plate or a part of the holding plate formed by the bag portion and the holding plate, in the above sense universal vacuum cleaner bag. In other words, in the former case, the combination of bag section and adapter element itself a universal vacuum cleaner bag in which the adapter element is the retaining plate of such a universal vacuum cleaner bag, and in the second case, the adapter device can be connected to a universal vacuum cleaner bag, which in turn has a retaining plate with predetermined dimensions and shapes. For this purpose, a connection section is then arranged on the second surface of the base element, by means of which the base element is connected to the holding plate of the universal vacuum cleaner bag can. In any case, such a universal vacuum cleaner bag is characterized in that it - and in particular its holding plate - regardless of the vacuum cleaner in which it is to be used, always the same, predetermined shapes and dimensions. In all these cases, instead of a holding plate and a non-plate-shaped retaining element can be used. The base element is further provided to be connected in the manner already mentioned on its first surface with a specifically adapted to a particular vacuum cleaner or its Staubsaugerbeutelhaltevorrichtung holding plate. In any case, the combination of a universal vacuum cleaner bag provided with such an adapter device of predetermined dimensions and shapes and a vacuum cleaner-specific holding plate, such as a regular vacuum cleaner-specific vacuum cleaner bag, can be mounted to the vacuum cleaner bag holding device adapted to the latter by means of the vacuum cleaner-specific holding plate.

The connection between the adapter device or the first surface of the base member of the adapter device - or to be regarded as an adapter device holding plate of a universal vacuum cleaner bag - with a vacuum cleaner-specific holding plate has been previously produced by means of an adhesive bond, the through hole of the adapter device in the bonded state at least partially overlaps the Halteplattendurchgangsbohrung and thus the suction air flow at the through-hole can flow through the adapter device.

However, it has been shown that such an adhesive connection does not - as would be necessary according to the purpose and purpose of the adapter device - ensure a reliable connection to various types of vacuum bags, which are ideally available to all holding plates, and which is permanently stable. This concerns, for example, certain materials that are often used for Holding plates are used, such as polyethylene or polypropylene. Corresponding low-energy plastics require a particularly reliable bonding before a special, complex surface treatment, which is a disadvantageous effort for a user. Especially in such materials without sufficient pretreatment, but also generally there is a great risk that the adapter device - promoted by during operation in the vacuum cleaner resulting heat and vibration - dissolves from the holding plate. As a result, the adapter device is unusable, and dust and dirt enter the interior of the vacuum cleaner. Moreover, in any case, the use of high-quality adhesives desired for a reliable connection entails such high costs that the adapter device becomes unprofitable.

For the reasons mentioned, universal vacuum cleaner bags and corresponding adapter devices have so far not prevailed on the market to a large extent. The consumer, therefore, if he needs a new vacuum cleaner bag, usually still has to check which vacuum cleaner bag type is right for his vacuum cleaner and then find and select it from one dealer, among many others.

It is an object of the present invention to provide an adapter device for attaching a vacuum cleaner bag to a holding plate, which is provided for receiving in a vacuum cleaner bag holding device of a vacuum cleaner and having a Halteplattendurchgangsbohrung, with the simple even during operation of the vacuum cleaner reliable and stable connection between the adapter device and different holding plates made of different materials can be made and the aforementioned problems of the prior art are avoided.

This object is achieved by an adapter device having the features of claim 1, a vacuum cleaner bag having the features of claim 13 and a method having the features of claim 15. Advantageous embodiments of the adapter device, the vacuum cleaner bag and the method are the subject of the respective dependent claims.

According to the present invention, an adapter device for fastening a vacuum cleaner bag is provided on a, preferably non-curved holding plate provided for receiving in a vacuum cleaner bag holding device of a vacuum cleaner and - in use the inlet opening forming - Halteplattendurchgangsbohrung or opening. For this vacuum cleaner-specific retaining plate and the general operation of the adapter device, the above explanations apply. Thus, in particular, the adapter device also has a base element, which has a first-preferably flat-surface and a second-likewise preferably flat-surface and a through-bore or opening which extends between the first and the second surface. The through-bore may also be referred to as an inflow port, since in use the dust flows through it into the interior of the vacuum cleaner bag. The first and the second surface are each a portion of the total surface of the base member, which - as will be explained later - in use, the first surface is preferably on the side facing away from the vacuum cleaner bag or is formed by this and in use the second surface preferably located on the side facing the vacuum cleaner bag or is formed by them.

As has been explained above, and as will become apparent hereinafter, the through-hole is intended to to be arranged in partially or completely overlapping orientation, and preferably in centered alignment with the mounting plate throughbore of a mounting plate which is attached to the adapter device, forming the inlet opening of the vacuum cleaner bag in use in the vacuum cleaner, through which dust from the pipe of the vacuum cleaner the interior of the vacuum cleaner bag passes.

The adapter device further comprises a clamping device, which in turn has at least one deformable or flexible clamping element which can be fastened to the base element or is preferably fastened and can be brought into a first and a second deformation state. As will be clear from the description of the mode of operation, the term of the second state of deformation may include various concrete states of deformation or shapes of the at least one clamping element, which are present depending on the specific configuration of the vacuum cleaner-specific holding plate. Instead, one could also speak of at least one second state of deformation.

The at least one clamping element and the base element are configured such that, after the at least one clamping element - and in the case of several clamping elements of each of these clamping elements - has been brought into the first deformation state, it is possible a vacuum cleaner-specific vacuum cleaner bag holding plate of the type described above that is, a holding plate provided with a holding plate through-hole connecting the extended opposite surfaces of the holding plate to each other so as to be laid on the first surface of the base member such that the holding plate abuts against the first surface of the base member and the through-hole of the base member completely or at least partially overlapping with the Halteplattendurchgangsbohrung, and again from the first surface can be removed. This includes, for clamping members which can be attached to and removed from the base member, the possibility that the at least one clamping member will be removed from the base member after it has been brought into the first deformation condition, then the support plate will be applied and finally the clamping member - After it has possibly been brought back into its first deformation state, if necessary - by being attached to the base member and bringing in the second deformation state or a second deformation state is attached to the base member again.

The at least one clamping element and the base element are further configured such that the at least one clamping element in its or a second deformation state - in the state attached to the base element - engages the surface facing away from the base element surface of a laid in the manner described holding plate and the holding plate holds the base element clamped. In other words, the holding plate is clamped between the base member and the at least one clamping element by the clamping element and the base member engage the opposite surfaces of the vacuum cleaner-specific holding plate.

It is possible that the at least one clamping element and the base member are configured such that the described arrangement of a vacuum cleaner-specific retaining plate to the base member after the at least one first clamping member has been brought into the first deformation state, and the described subsequent clamping of the retaining plate the base element is made possible by bringing the at least one clamping element in the second deformation state at least for vacuum cleaner-specific holding plates, wherein the Halteplattendurchgangsbohrung a diameter or radius of a - preferably predetermined - diameter or radius range has and whose thickness, in particular at the edge of the Halteplattendurchgangsbohrung, in a - preferably predetermined - thickness range or in which the value of a function of the diameter or radius and the thickness, eg the sum of the difference of thickness and radius and a constant, in a - preferably predetermined - range is or does not exceed a maximum value. However, it is preferred if any vacuum cleaner-specific retaining plates of the type mentioned can be used.

It has surprisingly been found that with the help of such clamping elements in a simple manner, a sufficiently strong connection between an adapter device for a vacuum cleaner bag and a vacuum cleaner-specific holding plate can be made. In this case, the through-hole of the base member can be precisely arranged and fixed with respect to the holding plate through-hole differently arranged and dimensioned from holding plate to holding plate, and it is possible to use vacuum cleaner-specific holding plates having differently shaped and dimensioned holding plate through holes. The clamp connection is also advantageously quickly detachable without the adapter device or the support plate are damaged and possibly unusable. In particular, unlike an adhesive bond, the surface of the vacuum cleaner-specific holding plate is not attacked. The adapter device is therefore reusable if the vacuum cleaner-specific holding plate associated with it has to be replaced, e.g. in the case of any other damage to the vacuum cleaner-specific mounting plate or a change of the vacuum cleaner model.

As has already been explained above, in the context of the present application under (hoover-specific) holding plate which is usually made of plastic or paperboard, on understood the opening of a vacuum cleaner bag plate through which the inflow opening of the vacuum cleaner bag - the so-called Halteplattendurchgangsbohrung - extends and which can be detachably connected to the Staubsaugerbeutelhaltevorrichtung with the vacuum cleaner so that one end of the vacuum cleaner tube or hose in the Halteplattendurchgangsbohrung and thus the Opening the vacuum cleaner bag engages. In order to connect a vacuum cleaner-specific holding plate with the adapter device according to the invention, the holding plate must first be separated from a matching vacuum cleaner for each vacuum cleaner bag and torn off, for example. After connecting the holding plate with an adapter device according to the invention can then in the manner already described above, each vacuum cleaner bag that can be connected to the adapter device or of which the adapter device forms an integral part by being firmly connected to a corresponding bag section, even with this special vacuum cleaner can be used. In this way, a universal vacuum cleaner bag can be provided in an advantageous manner.

The present invention thus advantageously provides an adapter device which can be easily and reliably attached to vacuum cleaner-specific holding plates after they have been separated from their vacuum cleaner bags, and the present invention thus makes it possible to use a vacuum cleaner bag which is independent of the respective vacuum cleaner model and make in all vacuum cleaners can be used.

In a preferred embodiment, the base member is plate-shaped or formed as a plate, wherein the first and the second surface are formed by the two extended surfaces of the plate-shaped base member. The base element can then also as a base plate or base plate be designated. The plate preferably has a round or circular shape in order to minimize the risk of the base element being stuck when it is inserted into the vacuum cleaner bag receiving space of a vacuum cleaner and when a vacuum cleaner-specific holding plate connected to the adapter device is attached to the vacuum cleaner bag holding device of the vacuum cleaner and allowing any angular orientation of the base element. but can also be, for example, square, rectangular or polygonal. In any case, it is advantageous if the plate-shaped base element is as thin as possible, so that in use in the vacuum cleaner possible impact and obstacle surfaces for the intake air to which dust can accumulate before reaching the Staubsaugerbeutelinneren. The through-hole is preferably arranged in the middle of the base element.

If the base element is not plate-shaped, however, it is also conceivable that the first and second surfaces do not run parallel to one another.

The throughbore preferably has a round, and more preferably a circular, cross-section, since retention plate through holes, i. Halteplatteneinströmöffnungen, typically have such a cross-section. Furthermore, the through-bore is preferably dimensioned so that its diameter is greater than the diameter of Halteplattendurchgangsbohrungen hoover-specific retaining plates, so that the use of the adapter device, the normal suction power of the vacuum cleaner is not reduced.

The base element is preferably made of plastic, preferably by an injection molding process. But it can also be used cardboard or metal or combinations of the materials mentioned. Coatings can also be used.

In a preferred embodiment, the at least one deformable clamping element is configured such that it is or can be attached in such a way to the base element and preferably at the edge or in the vicinity of the edge of the through hole, that in the second deformation state of the base element or from the edge of the through hole through the Halteplattendurchgangsbohrung a holding plate - and possibly depending on the mounting location through the through hole of the base member passes - which - as described above - placed after bringing the at least one clamping element in the first deformation state on the first surface of the base member has been. In other words, the at least one clamping element engages through the holding plate passage bore - and possibly also through the through hole of the base element - on the surface of the holding plate facing away from the base element. It is preferably from the edge of the through hole. It is expressly understood that the attachment of the at least one clamping element itself can be provided away from the edge of the through hole and the at least one clamping element then initially extends in the direction of the edge and finally in the manner described by the base member or from the edge of the Through hole passes through the Halteplattendurchgangsbohrung a holding plate.

It is preferred that at least two deformable clamping elements are provided, each having the described configuration and operation. It is particularly preferred if the clamping device has two to four and in particular three clamping elements and particularly preferably four. Already with three or four clamping elements a precise positioning and reliable fixing of the through hole with respect to the holding plate through hole of a holding plate is possible in a simple manner. It has also been found that it is possible with four clamping elements, which are preferably spaced apart uniformly in the circumferential direction of the edge of the through hole in an advantageous manner, sealing material, which is usually provided on vacuum cleaner-specific holding plates and from the edge of the Halteplattendurchgangsbohrung protrudes inwardly, in the direction of the edge to press on the outside, to avoid an impairment of the suction power. Depending on the material of the base member and the strength of the clamping elements but also fewer clamping elements may be sufficient or more clamping elements may be required.

It should be noted that it is also possible that in addition to a deformable clamping element or a plurality of deformable clamping elements of the type described at least one rigid clamping element is provided which is fixed to the base member and the holding plate in cooperation with the at least one deformable clamping element on the Can hold the base element. Such a rigid clamping element, which may be formed, for example, hook-like, then has an engagement portion into which the holding plate can be inserted for engagement, while the at least one clamping element is in the first deformation state or is removed from the base element. The at least one deformable clamping element can then be brought from the first deformation state into the second deformation state, possibly after being arranged on the base element, whereby it engages with the retaining plate and clamps it tightly against the first surface of the base element and thus also prevents it from coming off rigid clamping element is disengaged from the holding plate. Such rigid clamping elements can cause additional fixation, but have the disadvantage that differently sized retaining plates can be difficult to take into account.

In a preferred embodiment in which there are at least two deformable clamping elements which, as described above, are or may be secured to the base member and, for example, at the edge or near the edge of the throughbore, in the second deforming state of FIG extend the base member or from the edge of the through hole through the Halteplattendurchgangsbohrung a vacuum cleaner-specific holding plate, the at least two clamping elements are secured in the manner of the base member or may be attached to the base member in such a way that they are uniform in the circumferential direction of the through hole of the base member are spaced. Thereby, a uniform clamping force can be provided along the circumferential direction of the through hole, and inadvertent release of the base member from the holding plate and undesirable relative displacement of the base member are further hindered.

The at least one deformable clamping element may be elastically deformable or resilient, wherein it is biased in the first deformation state in the direction of the second deformation state. In other words, such a clamping element exerts an increasingly greater elastic force when it is brought from the second to the first deformation state, and this restoring force causes in use the clamping force acting on the holding plate. An elastically deformable clamping element may be provided in the form of a resilient clip and may either be fixedly attached to the base member or separate from the base member and fixed to the base member only upon movement into the second deformation condition.

However, it is preferred that at least one of the at least one clamping element and preferably each of the at least one clamping element between the first and the second deformation state is plastically deformable or flexible. As such a plastically deformable or flexible clamping element can advantageously find an elongated element use, which is for example in the form of a web or a tab member as in a folder and is flexible along its length or is plastically deformable. The elongated element may, for example, have a round, rectangular, square or polygonal cross section. However, it is preferred that the elongate element is flat or flat. Plastically deformable or flexible clamping elements have the advantage that a bending force has to be exerted only during the movement between the first and the second deformation state. However, if the first or second deformation state is reached, then the clamping element remains stable in this state, without further forces must be exercised. They are therefore easier for the user to handle than elastic clamping elements. In addition, the possibility of attaching differently shaped and dimensioned holding plates can be ensured particularly easily and reliably with plastically deformable clamping elements.

If at least one plastically deformable or flexible clamping element is provided, it is further preferred if the at least one plastically deformable clamping element at least partially extends in the first deformation state from the edge of the through hole of the base element in the direction of an axis of the through hole and in particular with at least one Part extends radially into the through hole.

In this context, it should be noted that the invention in other words structurally quite generally relates to an adapter device for attaching a vacuum cleaner bag to a vacuum cleaner-specific holding plate of the type described above, wherein the adapter device, a base member having a first - preferably flat - surface and a second - also preferably flat - surface and a through hole or opening and a clamping device, which in turn has at least one deformable or flexible clamping element which can be attached to the base member or preferably fixed and in a first and a second deformation state can be brought, wherein the at least one clamping element is plastically deformable or flexible, in the first deformation state at least partially extends from the edge of the through hole of the base member in the direction of an axis of the through hole and in particular with at least one part radially into the through hole and, when brought from the first to the second deformation state, is partially bent in the axial direction extending from the second to the first surface and partially radially outward. The base element and the clamping device can have the structural configurations detailed above and below. For example, the at least one clamping element may be formed as an elongated web.

Regardless of the configuration, the clamping elements may be formed from various coated or uncoated materials, such as wire, metal foil, spring steel or sheet metal. A coating may be formed of plastic.

In a preferred embodiment, the first surface of the base element has a sealing layer surrounding the through-hole. This sealing layer forms part of the first surface of the base element and is preferably arranged in a closed ring shape and is preferably located in the immediate vicinity of the through-hole. The sealing layer is preferably formed of an elastically compressible material, such as foam, silicone or a nonwoven material. Such a sealing layer has the advantage that After fixing a holding plate to the base element any unevenness of the holding plate are compensated and at the same time formed by the through hole of the base member and the Halteplattendurchgangsbohrung Saugströmungskanal between the holding plate and base member is sealed in the radial direction, so that the vacuum cleaner draws no secondary air between these two components, whereby the Suction would be reduced or possibly dust and dirt could escape.

In an advantageous embodiment, a sealing ring made of flexible or elastic material is provided at the edge of the through hole, which extends from the edge radially into the through hole. Such a sealing ring, which - as mentioned above - is typically also provided on vacuum cleaner-specific holding plates, has the task to seal an existing gap between the edge of the through hole and the suction nozzle of a vacuum cleaner. A suitable material for forming the sealing ring is latex.

In a preferred embodiment, a holding device for holding a preferably predetermined dimensions and shapes connecting portion of a vacuum cleaner bag portion to the base member is provided on the second surface. The holding device can be designed, for example, such that a plug connection, a snap connection, a hook connection or a flange connection is or is produced with the connection section of the vacuum cleaner bag section. The holding device may, for example, also have a rail device into which the connection section is or is inserted, the connection section in this case or in the other cases being able to be designed as a holding plate or a differently shaped holding element of a (universal) vacuum cleaner bag which houses the vacuum cleaner bag section and has the connection portion or through this is formed. Such a (universal) holding plate may preferably be round or circular. The holding device can hold the connection section firmly or detachably. In the former case, the holding device can also be formed, for example, by adhesive, wherein the connection section is approximately simply a part of the bag section in the immediate vicinity of the edge of the opening of the bag section. In the latter case, it is preferred if the holding device and the connecting device are formed in their dimensions and shapes complementary to each other, so that they can fit together. With the help of the adapter device can in this way each vacuum cleaner bag, the connection portion is connected to the holding device of the adapter device or can be connected to that vacuum cleaner whose matching vacuum cleaner specific holding plate is just connected to the adapter device. In any case, the adapter device and the vacuum cleaner bag section, which in the case of a releasable attachment with its connection portion in the manner explained above can already be considered as a universal vacuum cleaner bag, after connection between the holding device and the terminal portion a universal vacuum cleaner bag by attachment a vacuum cleaner specific plate can be adapted to a specific vacuum cleaner.

In a preferred embodiment, the adapter device has a closure element, which is pivotally attached to the base member and can be pivoted into a closed state in which it closes and seals the through-bore. In particular, such a closure element may preferably be designed as a closure flap. The closure element can then be brought into the closed state in an advantageous manner when a vacuum cleaner bag section connected to the adapter device is filled with dust and dirt and together for replacement is separated with the adapter device of the vacuum cleaner to prevent leakage of the dust and dirt received in the interior of the vacuum cleaner bag. The clamping elements are preferably designed and arranged so that they can be brought into a third deformation state in which they fix the closure element in its closed state, or that they fix the closure element in its closed state in its first deformation state. In this context, in particular the above-mentioned plastically deformable elongate clamping elements, for example in the form of webs or tabs, are advantageous.

The adapter device described can be advantageous in the manner already explained part of a vacuum cleaner bag having a bag portion which is provided for storing dust and dirt in its interior and having an opening, and a connection portion which is fixed or detachably connected to the adapter device in that the through hole of the base member is aligned with the opening of the bag portion. The bag portion is preferably formed of fabric as in conventional vacuum cleaner bags. It is preferred that the adapter device is firmly connected to the connection section. The adapter device then forms an integral part of the vacuum cleaner bag and can be referred to as its retaining plate or retaining element. In this case, the at least one clamping element is at least one adapter means with which such a (universal) holding plate or such a universal holding element can be easily and reliably connected to a vacuum cleaner-specific holding plate.

In this context, it should be noted that a vacuum cleaner bag according to the invention can structurally also quite generally be described by having a bag section and an adapter device connected thereto for attachment the vacuum cleaner bag on a vacuum cleaner-specific retaining plate of the type described above, wherein the adapter device comprises a base member having a first - preferably flat - surface and a second - also preferably flat - surface and a through hole or opening, and a clamping device, the in turn has at least one deformable or flexible clamping element which can be fastened to the base element or is preferably fastened and can be brought into a first and a second deformation state. It is then preferred if the at least one clamping element is plastically deformable or flexible. Furthermore, it is preferred if the at least one clamping element in the first deformation state extends at least partially from the edge of the through hole of the base element in the direction of an axis of the through hole and in particular with at least one part extends radially into the through hole and when brought out of the first is partially bent in the second deformation state in the axial direction extending from the second to the first surface and partially radially outward. The base element and the clamping device can have the structural configurations detailed above and below. For example, the at least one clamping element may be formed as an elongated web.

Another aspect of the present invention relates to a method for connecting an adapter device for a vacuum cleaner bag with a holding plate, which is provided for receiving in a vacuum cleaner bag holding device of a vacuum cleaner.

In a first step of the method, a vacuum cleaner-specific holding plate of the type already described is provided, which is provided for receiving in a vacuum cleaner bag holding device of a vacuum cleaner and by a Having the holding plate formed Halteplattendurchgangsbohrung. As has already been explained, such a retaining plate can be removed, for example, from a vacuum cleaner bag which is suitable for the respective vacuum cleaner.

Furthermore, an adapter device is provided, as has been described in detail above, wherein the at least one clamping element is in the first deformation state or is removed from the fastening element. Thus, the at least one clamping element does not yet engage the holding plate, but allows the holding plate to be placed on the first surface of the base element and away from the first surface of the base element.

Subsequently, the holding plate is placed in the manner already explained in detail on the first surface of the base member. In this case, the through hole of the base member is aligned with the Halteplattendurchgangsbohrung, preferably a maximum overlap is made.

Finally, the at least one deformable clamping element - possibly brought after arrangement on the base member from the first deformation state in the second deformation state, wherein the at least one deformable clamping element engages with the base member remote from the surface of the holding plate and clamps the holding plate to the base member.
