Vacuum Cleaner Bag Mounting Structure
An apparatus is configured for use with a vacuum cleaner filter bag having a collar panel with an inlet opening. A support structure receives the panel in an installed position in which a tubular part of the vacuum cleaner extends into the bag through the inlet opening. The support structure includes a tab that retains the panel in the installed position. The support structure further includes a pivot that abuts an edge of the panel to guide movement of the panel into the installed position pivotally about the abutting edge.
This technology relates to a vacuum cleaner bag and a vacuum cleaner upon which the bag is installed.
BACKGROUNDA disposable filter bag for a vacuum cleaner has a mounting collar for mounting the bag on the vacuum cleaner. The mounting collar includes a paperboard panel that is adhered to the bag at the inlet opening into the bag. A tubular part of the vacuum cleaner is configured to convey debris-laden air into the bag. The bag is mounted on the vacuum cleaner by placing the mounting collar over the tubular part.
SUMMARYAn apparatus is configured for use with a vacuum cleaner filter bag having a collar panel with an inlet opening. The apparatus includes a tubular part that conveys debris-laden air into the bag. The apparatus further includes a support structure that receives the panel in an installed position in which the tubular part extends into the bag through the inlet opening. The support structure has a tab that retains the panel in the installed position, and has a pivot that abuts an edge of the panel to guide movement of the panel into the installed position pivotally about the abutting edge.
The apparatus shown in the drawings has parts that are examples of the elements recited in the claims. The following description thus includes examples of how a person of ordinary skill in the art can make and use the claimed invention. It is presented here to meet the statutory requirements of written description, enablement, and best mode without imposing limitations that are not recited in the claims.
As show schematically in
In operation, a fan 40 within the base 12 generates a flow of air, indicated by the arrows 43. Debris, such as dirt from household surfaces, is entrained in the air. The debris is transported by the air through the nozzle 16 to the fan 40. The fan 40 drives the debris-laden air upward through the fill tube 24 and through the adaptor 26 into the inner bag 30. The air escapes through the inner bag 30 and the outer bag 32 to the atmosphere, and the debris is retained in the inner bag 30.
As shown in greater detail in
The support structure 46 further includes a support panel 60. A pair of flexible locking tabs 64 project forward from the lower end of the panel 60 on opposite sides of the adaptor tube 44. A pair of retainer brackets 66 project forward from the upper corners of the panel 60 on opposite sides of the adaptor tube 44. The panel 60 and the brackets 66 together define a pair of slots 71 that are open between the panel 60 and the brackets 66.

The patentable scope of the invention is defined by the claims, and may include other examples of how the invention can be made and used. Such other examples, which may be available either before or after the application filing date, are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they have equivalent structural elements with insubstantial differences from the literal language of the claims.
Claims
1. An apparatus for use with a vacuum cleaner filter bag having a collar panel with an inlet opening, the apparatus comprising:
- a tubular part configured to convey debris-laden air into the filter bag; and
- a support structure configured to receive the panel in an installed position in which the tubular part extends into the bag through the inlet opening, including a tab configured to retain the panel in the installed position, and a pivot configured to abut an edge of the panel to guide movement of the panel into the installed position pivotally about the abutting edge.
2. An apparatus as defined in claim 1 wherein the pivot is defined by an inside corner of the support structure.
3. An apparatus as defined in claim 1 wherein the pivot defines a pivotal axis that is horizontal when the tubular part is upright.
4. An apparatus as defined in claim 1 wherein the pivot is one of a plurality of pivots spaced apart along a common pivotal axis.
5. An apparatus as defined in claim 1 wherein the tab is a locking tab configured to snap into engagement with the panel upon movement of the panel pivotally into the installed position.
6. An apparatus as defined in claim 5 wherein the support structure further includes a non-locking tab configured to align the panel with the installed position.
7. An apparatus as defined in claim 1 wherein the tubular part comprises an elbow with a bend of more than 90°.
8. An apparatus as defined in claim 1 wherein the support structure is part of a unitary structure that includes the tubular part.
9. An apparatus as defined in claim 8 wherein the unitary structure is a bag top adaptor.
