Definitions

• the present invention relates to a vacuum cleaner bag, and to a system for fixing such a bag to the device.
• the invention also relates to a vacuum cleaner using such a bag or such a fastening system.
• a type of vacuum cleaner bag commonly used comprises a porous envelope and a rigid plate integral with the porous envelope, said rigid plate having a first opening for passage of the sucked air, at least one locking window intended for the reception of '' a locking member belonging to a fastening device integral with the housing of a vacuum cleaner, as well as a shutter plate slidably mounted on the rigid plate and provided with a second opening substantially of the same dimensions as the first opening, so that in a “retracted” position of the shutter plate, the first and the second opening substantially coincide, and that in a “functional” position, the shutter plate closes the first opening.
• a vacuum cleaner bag of this type is intended to be removably mounted in the housing of a vacuum cleaner; it is designed so that the user, when he wishes to remove a used bag from the device to change it, can place the sealing plate in the "functional" position, that is to say in the position where the first opening is closed, to prevent any leakage of dust contained in the used bag.
• the invention provides that the locking window can receive the locking member in the "retracted” position of the shutter plate, while, in its “functional” position, the shutter plate at least partially closes the locking window, so that the locking member is released from the window.
• FIG. 1 is a partial perspective view of the assembly consisting of a vacuum cleaner bag and a fixing device according to the invention
• FIG. 2 is a partial front view of a bag and a fastening device according to Figure 1, with two parts broken away the bag being removed;
• FIG. 3 is a perspective view of a fixing device alone according to the invention;
• FIG. 4 is a front view of the fixing device and the bag, in an intermediate position of the sealing plate
• Figures 4a and 4b are sections of the fastening device and the bag shown in Figure
• FIG. 5 is a front view of the fixing device and the bag, in a final position of the sealing plate
• FIGS. 5a and 5b are sections of the fastening device and the bag shown in Figure
• Figure 6 is a perspective view of the assembly shown in Figure 5, in the final unlocked position.
• FIG 1 there is partially shown a vacuum cleaner bag locked on the fixing device 1 of a vacuum cleaner.
• Vacuum cleaner bags of this type are placed in a housing, namely a compartment of the device subjected to the vacuum created by a motor-fan group, opposite an orifice of arrival of the air drawn in.
• This type of bag is designed to be easily replaced by the user, both at the time of installation and at the time of removal, with correct positioning of the bag in the housing of the device.
• the rigid plate 3 has a first opening
• two locking windows 5 each intended for the reception of a locking member 6 secured to the vacuum cleaner housing, as well as a shutter plate 7 slidably mounted on the plate rigid 3 and provided with a second opening 8 substantially of the same dimensions as the first opening 4, so that in a “retracted” position of the sealing plate 7, the first 4 and the second 8 openings substantially coincide, and that in a "functional" position, the closure plate 7 closes the first opening
• This arrangement aims to allow the user to close the first opening 4 when removing a used bag and handling it, in order to avoid any leakage of dust.
• the user must activate, for example by the handle P, the sealing plate 7, before the extraction of the used bag from the case: good handling consists in sliding the plate obturation 7 from its “retracted” position to its “functional” position, while the bag is still in place in the housing, then extracting the used bag from the housing.
• the vacuum cleaner bag according to the invention conditions the withdrawal from the housing bag to the prior actuation of the sealing plate 7 by the user.
• each locking window 5 can receive the corresponding locking member 6 in the "retracted” position of the closure plate 7, while, in its “functional” position, the closure plate 7 closes at least partially the locking window 5, so that the locking member 6 is released from the window 5.
• the closure plate 7 has two shoulders 9 intended to cooperate respectively, at the end of sliding of the plate 7 towards its "functional" position , with a lug 10 formed on each of the locking members 6.
• the invention also relates to a device for fixing a vacuum cleaner bag of the type described above.
• Such a fixing device 1 shown alone in FIG. 3, commonly comprises a support plate 11, which forms a flat support for the rigid plate 3 of the bag and has an opening extending the orifice 12 for air intake. sucked into the housing; two slides 2 integral with the vacuum cleaner housing, arranged symmetrically on either side of the orifice 12, and designed to receive the rigid sliding plate 3; it also includes two locking members 6, intended to maintain the bag in a correct operating position, in which the first opening 4 formed in the rigid plate 3 is located opposite the orifice 12.
• Each of the locking members 6 comprises an elastic bar 13, integral with the support plate
• the lug 10 has two distinct faces 15a, 15b facing the shoulder and linearly offset, the first of which 15a, substantially parallel to the plane of the shoulder 9 , is intended to cooperate with an edge 16 of the corresponding window 5, so as to oppose the extraction of the rigid plate 3 from the slides 2, and the second 15b, oblique to the plane of the shoulder 9 , forms a ramp on which the shoulder 9 rests at the end of sliding of the plate 7 towards its "functional" position, so as to release the lug 10 from the window 5.
• the invention relates both to a bag and fixing device described above, as to a vacuum cleaner comprising such a device or using such a bag.
• the invention meets a hygiene requirement, according to which a used vacuum cleaner bag must not be capable of leaking part of its contents, in particular during its user replacement. Thanks to the invention, the user is required to operate the handling of the used bag in a sequence suitable for ensuring optimum efficiency of the closure system.
