Problems solved by technology

[0007] The known solutions therefore have in common that they are either complex and thus expensive in terms of production technology, or they take up too much space in view of the compactness in the installation space of today's vacuum cleaners

Embodiment Construction

[0070] figure 1 An exemplary retaining plate 1 is shown comprising a base plate 2 with access openings 3 formed therein. In addition, two closure parts 4 , 5 interconnected via a connecting element 6 can be observed. The closing parts 4 , 5 are arranged in a plane extending parallel to the passage opening 3 and thus parallel to the base plate 2 . The closing parts 4 , 5 are shown in the open position, ie they do not block the passage opening 3 . The closing parts 4 , 5 are configured such that they are laterally displaced relative to the passage opening 3 . In the present example, the closure parts 4 , 5 are configured symmetrically about an axis 7 which extends parallel to the plane of the passage opening 3 . In this example, the passage opening 3 as well as the base plate 2 are also configured symmetrically with respect to the axis of symmetry 7 .

[0071] figure 1 Also shown are two raised portions or protrusions 8 , 9 provided on the base plate 2 . As will be clear f...

Abstract

The invention relates to a retaining plate (1) for a vacuum-cleaner filter bag, comprising a base plate (2), in which a through-passage opening (3) is formed, and a closure device for closing the through-passage opening (3), wherein the closure device comprises two closure parts (4, 5), which are arranged in a plane parallel to the through-passage opening (3), and wherein the closure parts (4, 5)can be moved in relation to one another in the plane, and this means that a closing movement in the plane can move the closure parts into a closure position, in which they close the through-passage opening (3), each closure part overlapping with part of the through-passage opening (3) in the process.

Description

technical field [0001] The invention relates to a holding plate for a filter bag of a vacuum cleaner, comprising: a base plate formed with a passage opening and closing means for closing the passage opening. Background technique [0002] Such retaining plates are known in various forms for arranging vacuum cleaner filter bags in vacuum cleaner housings. The closure device serves in particular to close the passage opening introduced into the bag after the bag has been used, in order to prevent accidental escape of the inhaled material. Various solutions have been proposed for the closure mechanism, for example, sliding solutions or folding solutions. [0003] Simple sliding solutions are known, for example, from EP 1 284 629 or from DE 10 2006 055 890. However, this solution has the disadvantage that, when viewed in the direction of movement of the slide, the retaining plate must be at least twice as large as the passage opening, so that the actual closing element can be mo...
