Description

Connection plate for dust container of vacuum cleaner

The present application is a divisional application filed on 2016, 9/5, under the name of 2016800854771, entitled "connecting plate for dust container of vacuum cleaner".

Technical Field

The present disclosure relates to a connection plate for a vacuum cleaner dust container, the connection plate comprising an opening and being adapted to position the opening correctly within the vacuum cleaner by inserting the connection plate into a holder of the vacuum cleaner.

Background

Examples of such connection plates are disclosed, for example, in WO-02/24046-A1. Due to the connection plate, the opening of the dust bag can be reliably positioned and oriented to receive the dust-laden air flow from the vacuum cleaner inlet. Further, the connection plate may trigger a feedback switch in the holder of the vacuum cleaner to verify that the dust container has been correctly mounted in the holder, thus enabling to prevent the use of the vacuum cleaner without or incorrectly mounted dust container. Otherwise, such use may damage the vacuum cleaner by injecting heavily dusty air into the fan/motor arrangement.

One problem associated with such dust containers is how to make it easier for the end user to handle them.

Disclosure of Invention

Accordingly, it is an object of the present disclosure to provide a dust container that is easier to use. This object is achieved by a dust container connection plate as defined in claim 1. More specifically, a web of the initially mentioned kind comprises a central portion surrounding the opening, and an extension portion protruding from the central portion along a plane in which it lies. The connecting plate further includes a shroud that is made in one piece with the connecting plate and is slidable to cover the opening, wherein the shroud is connected to the central portion on the side of the extending portion. With this arrangement, the shutter may close the dust bag opening by pulling away from the extension. Since the extension may include a locking feature that properly retains the connection plate in the retainer, the shutter may be configured to close the opening before the connection plate begins to move entirely out of the retainer. This reduces the risk of spilling dust when replacing the dust container.

The extension portion may comprise lateral arm portions extending from the central portion, and a bridge portion interconnecting the arms at their distal ends, wherein the flexible shutter is attached to the central portion between the arm portions. This provides space between the arms where the shutter can be positioned. The bridge portion may include a locking opening. The locking openings may be positioned laterally on the bridge portion within the lateral extension of the opening closed by the shutter, with reference to the insertion direction of the connecting plate.

The connecting plate may further include guide tabs on each side of the opening such that the shutter may be folded over the central portion and inserted behind the guide tabs. The shutter opening may be aligned with the opening of the dust bag.

For ease of use, the distal end of the shield may include a handle.

The connection plate may be integrally made of polypropylene (PP).

A tab may extend transversely from the central portion at least at one of the corners furthest from the extension portion, and a washer may be attached to the web at the opening.

Detailed Description

The present disclosure relates to a dust container for a vacuum cleaner, as shown by way of example in fig. 1. The dust receptacle has a dust bag 5, which is schematically indicated and is made of a gas-permeable material, as is well known per se. The web 3 is attached to the dust bag 5 (e.g. by gluing to the dust bag) and has an opening 9 which coincides with the opening in the dust bag 5, so that the opening of the web as a whole also becomes the opening of the dust bag. The attachment plate 3 is configured for positioning the opening 9 of the dust bag in a correct manner with respect to the air inlet in the vacuum cleaner body. This may be achieved by sliding the connecting plate into a holder or socket in the vacuum cleaner. This operation positions the opening 9 to receive a dusty airflow whereby it enters the bag which removes most of the dust from the airflow. A gasket 7 may be attached to the web 3 at the opening 9 to provide a sealing function to reduce leakage in the flow from the inlet hose to the bag 5.

Fig. 2 shows a plan view of the connection plate 3. In the present disclosure, the web 3 includes a central portion 11 that is central with respect to the opening 9 around which it surrounds, and that may be substantially flat and rectangular. Further, the web 3 comprises an extension 13, which may protrude from an edge of the central portion 11.

When using the connection plate 3 in a vacuum cleaner, the connection plate can be slid into a holder in the vacuum cleaner, with the extension part leading in the insertion direction and the central part as the subsequent part. The width of the central portion 11 and the extension 13 may be a substantially uniform width from the distal edge 29 of the extension that is inserted first to the edge 31 of the central portion 11 opposite the distal edge 29. This allows the holder to guide the insertion of the connection plate. A tab 14 extending transversely from the central portion 11 at the corner furthest from the extension 13 may be provided to rest outside the holder at the entry point of the holder.

The central and

extension portions

11, 13 may extend in a common plane and may be made in one piece, for example by injection moulding polypropylene (PP). The central portion and the

extensions

11, 13 together provide a secure fixation of the dust bag opening 9 in the vacuum cleaner. In addition, the extension 13 may provide a locking function that retains the connection plate in the holder; and an indicating function which triggers a sensor or switch in the holder so that the vacuum cleaner is aware that the dust bag is being correctly inserted, thereby allowing the vacuum cleaner to disable the suction function unless the dust bag is correctly fitted.

As further illustrated in fig. 2, the extension portion 13 may include lateral arm portions 17 extending from the central portion 11 and a bridge portion 15 interconnecting the arms at their distal ends. This serves to leave free space between the arm portions 17, which free space is available to the shutter arrangement as will be shown. The bridge portion 15 may comprise locking openings 19 which interact with locking means which snap into the openings when the attachment plate is assembled, whereby a predetermined pulling force is required in a direction opposite to the insertion direction in order to remove the dust bag. Thereby, the dust bag is not unintentionally taken out. As illustrated, the locking opening 19 may be positioned transversely on the bridge portion 15, within the transverse extension of the opening 9 with reference to the insertion direction of the connecting plate.

The present disclosure relates to a shutter 21 which may be used to close the opening 9 once the dust bag 5 is full and the dust container 1 is to be replaced. Since the shutter 21 substantially seals the opening 9, leakage of collected dust from the dust bag when being handled for disposal can be prevented to a large extent.

In the present disclosure, the shield is connected to the central portion 11 between the lateral arm portions 17 and may be made in one piece with the remainder of the connecting plate. Referring to fig. 3 and 4, the shutter 21 has an opening 33 and is folded to the top of the central portion 11 such that the shutter opening 33 coincides with the opening 9 of the dust bag 5, which is shown in fig. 2. The shutter is tucked under the guide tabs 25 provided on both sides of the opening and is still slidable under the guide of the guide tabs 25 and the rear surface 27 behind the guide tabs. Thus, the shutter may be slid upwards in fig. 2, so that the shutter opening 33 is moved away from the dust bag opening 9, thereby effectively closing the opening. This state is shown in the perspective view of fig. 3. The distal end of the shutter may include a handle 23 to facilitate such manipulation.

The present disclosure relates to a dust container having improved handling characteristics. Referring to fig. 4, a perspective view of the connecting plate is shown, wherein the shutter has not yet been folded over the opening of the connecting plate.

Typically, a web 3 is provided having a central portion 11 surrounding the dust bag opening 9, and an extension portion 13 protruding from the central portion 11. The connecting plate 3 comprises a shutter 21, which may be made in one piece with the connecting plate and is slidable so as to cover the opening 9. The shroud 21 is connected to the central portion 11 on the side of the extension 13.

Referring to fig. 2, one advantage of such a connection plate is that the shutter 21 is activated by pulling the shutter 21 away from the extension 13, thereby closing the opening 9. In the example shown, the bridge portion 15 of the extension portion comprises a functional portion 19 for locking the connection plate 3 in the holder. This means that the opening can be completely closed without starting to remove the connection plate 3 from the holder. The sliding resistance of shutter 21 may be less than the force required to unlock bridge portion 15 from the retainer. Thus, when the user pulls the handle 23, the connecting plate 3 does not disengage from the holder until the opening is completely closed, thereby preventing dust from leaving the dust bag (which might otherwise be the result of removing the dust container when the opening 9 is completely or partially uncovered).

Fig. 5 shows a side view corresponding to fig. 4. As shown, fold 55 is disposed proximate bridge portion 15. One advantage of this configuration is that the fold 55 can be used to complete the web 3 by further folding the shutter 21 at the fold 55 and using guide tabs to attach the distal portion of the shutter 21 at the central portion 11, as previously described.

Fig. 6 shows an enlarged portion of fig. 5. As shown, the shutter may have a ribbed structure that guides the shutter to bend in the direction of its deformation as it slides over the central portion. Thus, the ribs extend transversely to the direction in which the shutter 21 extends from the remainder of the connecting plate 3.

The disclosure is not limited to the examples described above and may be varied and altered in different ways within the scope of the appended claims. For example, other plastic materials may be suitable for this purpose, such as Polyethylene (PE).
