US 7,118,607 B2 · Filter stop for a vacuum cleaner

Abstract

A filter stop for a vacuum cleaner contains a dust chamber that is closable with a lid and receives a dust bag with a reinforcement plate in a specific fitting position. The filter stop has a base plate that is movable between two stopping positions parallel to the direction in which the reinforcement plate of the dust bag is inserted into the dust chamber. The filter stop is also provided with a swiveling lever that can be brought into a position activating the vacuuming function of the vacuum cleaner by the reinforcement plate when the dust bag is correctly positioned. The swiveling lever is in a position preventing the vacuuming function from being activated when the dust bag is not correctly positioned. The filter stop can be brought into a stop position activating the vacuuming function exclusively when the swiveling lever is actuated by a shoulder of the reinforcement plate.

Dependent claims

A filter stop for a vacuum cleaner having a dust chamber which can be closed by a cover and intended for accommodating a dust-retention device with a reinforcement plate in a defined installation position, the filter stop comprising:

a base plate to be displaced between two stop positions, parallel to a pushing-in direction of the reinforcement plate of the dust-retention device, said base plate having a pivoting lever, said pivoting lever can be pivoted, by a shoulder of the reinforcement plate of the dust-retention device disposed at a correct installation position, into a first stop position of the two stop positions, which allows a vacuuming-function-releasing stop position of said base plate to be reached, and, with the dust-retention device disposed outside the correct installation position, said pivoting lever is disposed in a position which prevents the first stop position of said base plate from being reached.

A vacuum cleaner comprising:

a housing defining a dust chamber and having a cover being movable between an open condition providing access to the dust chamber and a closed condition closing the dust chamber;
a guide rail supported by the housing and disposed within the dust chamber;
a dust-retention device having a reinforcement plate being received by the guide rail in a pushing-in direction, the reinforcing plate having a shoulder projecting outwardly from the reinforcing plate;
and
a filter stop supported by the housing for movement between a first stop position, in which the dust retention device is correctly positioned and the vacuum cleaner is operable, and a second stop position, in which the filter stop prevents the cover from being in the closed condition, the filter stop including a lever disposed along an edge of the filter stop adjacent the reinforcing plate and being movable between an extended condition, in which the lever restricts movement of the filter stop toward the first stop position, and a retracted condition, in which the lever permits movement of the filter stop toward the first stop position, the shoulder engaging the lever and moving the lever toward the retracted condition when the dust-retention device is in a correct installation position.
