Problems solved by technology
Here, the disadvantage is that during operation of the vacuum cleaner, this spring element is always positioned in the flow path of the air flow, so that dirt collects on the spring
This dirt, often in the form of fibers, impairs the function of the spring and the closing function of the flap
Moreover, tension springs are prone to high wear caused by impacts of dirt particles

Embodiment Construction
[0056] figure 1 is a schematic top view (direction opposite to the opening direction) of the retaining plate 1 according to the invention. Said retaining plate 1 comprises a base plate 2 provided, for example, in the form of an injection-molded part of plastic material. Formed in the base plate 2 is a through-opening 3 which is closed in the example shown by a closure element or closure cover 4 . The closure element 4 and the base plate 2 are integrally produced as an injection-molded part, the closure element 4 being connected to the base plate 2 via a film hinge 5 forming the pivot axis.
[0057] Furthermore, a spring element 6 is provided in the form of a leaf spring to hold the closing element 4 in the first shown position, ie the closed position. The longitudinal ends 7 of the leaf springs 6 are firmly connected to the base plate 2 by embedding them in plastic material. The other longitudinal end 8 is movably positioned on the closure element 4 . The leaf spring 6 is ...

The invention relates to a holding plate (1) for a vacuum cleaner bag with a base plate (2) with an opening (3), a locking element (4) arranged on the base plate with a horizontal swing to close the opening, and a spring element (6) arranged in such a way that the bending angle (B) of the spring element with a horizontal swing of the locking element in the opening direction brings the locking element out of the first position, in which the opening (3) is sealed, into the second position, in which the opening is open, in a previously determined swing angle (beta) range that is smaller than the corresponding opening angle (alpha) of the locking element (4), in such a way that the locking element can be brought from the second position into the first position by the restoring force of the spring element in the direction opposite to the opening direction, and the spring element is located behind the locking element in the opening direction.
Description
technical field [0001] The present invention relates to a holding plate for a vacuum cleaner filter bag and a vacuum cleaner filter bag including the holding plate. Background technique [0002] Vacuum cleaner filter bags are arranged inside the housing of the vacuum cleaner to collect inhaled dust. In order to fasten the vacuum cleaner filter bag inside the housing, the vacuum cleaner filter bag comprises a corresponding holding plate via which the vacuum cleaner filter bag can be fastened to a holding device arranged inside the housing. [0003] The holding plate comprises a through-opening through which an airflow carrying dust particles can enter the interior of the filter bag. A number of reasons make it desirable that the through-opening be able to be closed. On the one hand, the closed through-opening prevents the dust accumulated in the filter bag from escaping when the filled vacuum cleaner filter bag is discarded. Additionally, some vacuum cleaner filter bags in...
