- the rigid zone 1a produced for example in plastic and / or cardboard material, consists in particular of a guide means 4 and a shutter 5 for closing and opening the bag 1.
- the guide means 4 is made from a rigid material, by cardboard example, which comprises a profiled perforation 4a for guiding the shutter 5 for closing and opening the filling inlet of the bag 1.
- the shutter 5 for shutter is mounted in the rigid zone 1a, which is provided with the profiled perforation 4a, the shape and contour of which provide the guide means 4 in which moves the shutter 5.
- the profiled perforation 4a formed in the guide means 4, has an ear shape associated with a recess 4b, the shutter 5 closing partially conforming by its shapes to the profiled perforation 4a and having a surface smaller than the profiled perforation 4a to allow the rotation of said shutter 5, which is driven by a drive means 10 integral with a tongue 5c associated with the shutter 5, the shape of which is conjugated with the recess 4b.
- the latter therefore serves as a housing for the tongue 5c, so as to be able to rotate in the recess 4b and thus materialize an axis of rotation of the flap 5.
- the profiled perforation 4a is therefore in the form of a virtual ear.
- the shutter 5, partially hugging its profiled perforation 4a also has an ear shape consisting of a solid lobe 5a and a perforated lobe 5b.
- the solid lobe 5a and the perforated lobe 5b are attached to the tongue 5c so that the latter can fulfill the role of a pivot shaft.
- the tongue 5c is preferably centered on a center line or line of symmetry, not shown in the figures, of the ear representing the solid lobe 5a and the perforated lobe 5b.
- the recess 4b is thus also centered on a center line or line of symmetry, not shown in the figures, of the virtual ear defined by the profiled perforation 4a.
- the pivot shaft thus produced by the tongue 5c is centered on an axis xx ′ also schematically representing the axis of assembly of the different parts constituting the rigid zone la of the bag 1.
- the recess 4b is also centered on the axis xx '.
- the tongue 5c, the solid lobe 5a and the perforated lobe 5b are produced in a single piece, which is obtained for example by cutting from a cardboard sheet.
- the flap 5 is housed in the profiled perforation 4a and the conjugate forms, of the perforation 4a associated with the recess 4b and of the flap 5 associated with the tongue 5c, allow said flap 5 to be movable by rotation in the guide means 4 between an open position and a closed position of the filling bag 1.
- the profiled perforation 4a, and / or the recess 4b are also used as extreme stops against which the flap 5 comes to bear in one or the other of its position d 'opening or closing.
- the flap 5 consists of a single solid lobe 5a associated with the tongue 5c.
- the shutter 5 covers part of the surface of the profiled perforation 4a, so as to allow said shutter 5 to move in said profiled perforation 4a.
- the perforated lobe 5b is facing the filling inlet of the bag 1 and in the closed position of the flap 5, the full lobe 5a is facing the filling inlet from bag 1.
- the rigid zone 1a of the bag 1 consists of an assembly forming a sandwich structure including a fixing plate 2 integral with the bag 1 and provided with an orifice 2a, the guide means 4 having the profiled perforation 4a in which is housed the shutter 5 and a rigid front sheet 6 in which is formed an opening 6a so as to enclose the shutter 5 in the profiled perforation 4a.
- the rigid zone 1a consisting of plates or strips assembled successively, makes it possible to obtain optimum rigidity and flexibility for securing and detaching the bag 1 from the frame of the vacuum cleaner.
- the fixing plate 2, preferably made of a rigid material constitutes with the orifice 2a the filling inlet for the bag 1.
- the flap 5 is produced from the guide means 4 using a portion of material subtracted by any known means from said guide means 4, during the production of the profiled perforation 4a.
- the flap 5 is then cut so as to be movable by rotation in the profiled perforation 4a and to have opposite the orifice 2a, the perforated lobe 5b or the full lobe 5a to respectively open or close the access to the bag 1.
- the front rigid sheet 6 has an opening 6a centered on the orifice 2a.
- the rigid front sheet 6 is for example glued or stapled to the fixing plate 2 so as to secure the whole of the rigid zone 1a with the bag 1. The use of any other means of fixing the rigid front sheet 6 on the fixing plate 2 is possible.
- the thickness of the flap 5 is slightly less than the thickness of the guide means 4 so as to facilitate its rotation in one free space delimited by the fixing plate 2, the front rigid sheet 6 as well as by a defined surface. by the thickness of the guide means 4 and the contour of the profiled perforation 4a.
- the rigid zone 1a comprises a sealing membrane 3 in which a hole 3a is formed.
- the sealing membrane 3 is disposed between the fixing plate 2 and the guide means 4.
- the hole 3a is preferably made by two perpendicular incisions centered on the orifice 2a, on the opening 6a and on the perforated lobe 5b when the flap 5 is in the open position of the bag 1.
- the use of a sealing membrane 3 is particularly advantageous to make up for the play and therefore the sealing faults when a vacuum cleaner hose is in communication with the bag 1 through the opening 2a.
- the fixing plate 2, the sealing membrane 3 and the front rigid sheet 6 have respectively a bore 2b, 3b and 6b which allow the drive means 10, which is integral with the tongue 5c to pass through the latter and to transmit a rotational movement to it.
- the drive means 10 is controlled by a control member 11 actuated from outside the frame 13 of the vacuum cleaner, said drive means 10 being secured to the tongue 5c by means of a notch 5d formed in said tongue 5c.
- the frame 13 constitutes, of course, a housing or an external envelope of a suction assembly comprising in particular suction members of the motor / fan type.
- the notch 5d can be replaced by two perpendicular crossed notches.
- the drive means 10 has a shape complementary to the notch 5d.
- the assembly consisting of the fixing plate 2, the sealing membrane 3, the guide means 4, the flap 5 and the front rigid sheet 6, represented in FIG. 1, thus constitutes the rigid zone la bag 1.
- the control member 11 is mounted movable in translation above the rigid zone 1a to exert a deformation on said rigid zone allowing it to separate the bag 1 from the frame 13 of the vacuum cleaner.
- the rigid zone 1a has sufficient flexibility to disengage from a flange 14 and a groove 14b when the user exerts pressure on the control member 11.
- the control member 11 returns to the initial position by translation after the bag 1 has been ejected via a spring 11a arranged in said control member 11.
- FIG. 2 shows a connection device between a vacuum cleaner hose and a dust collecting bag 1 arranged on the frame 13 of a vacuum cleaner, said device comprising a fixing nozzle 20 forming the end of the suction hose, means for locking the nozzle 20 on the frame 13 and the flap 5 for closing the bag 1 movable between an open position and a closed position of the filling bag 1.
- the device comprises the control member 11, and cooperation means arranged on the control member 11 and on the nozzle 20 to cooperate when the shutter 5 is in the open position and thus allow the locking of the nozzle 20 on the frame 13.
- the cooperation means consist for example of means of the male / female type.
- the device comprises a male means arranged on the nozzle 20 and a female means arranged on the control member 11.
- the latter comprises a male means arranged on the member 11 and a female means arranged on the nozzle 20.
- the cooperation means consist of a lug 21 arranged on the nozzle 20 and a recess 11b formed in a part of the control member 11, said lug 21 being housed in the recess 11b during the locking operation.
- Such cooperation is only possible when the control member 11, movable by rotation, is in a well-defined angular position. The latter corresponds to the open position of the means for closing the bag 1.
- a rotation of the control member 11 corresponds to a rotation of the drive means 10 which is mechanically integral with the control member 11.
- the nozzle 20 is connected to a flexible hose constituting the hose of the vacuum cleaner which is in free rotation relative to the nozzle 20 by means of any known means.
- the control member 11 is thus mounted movable by rotation to close or open the bag 1 on the one hand and by translation to separate the bag 1 from the frame 13.
- the means of cooperation between the nozzle 20 and the control member 11 are produced by the shutter 5 directly, preventing the locking operation from the nozzle 20. The latter abuts against the shutter 5 when the latter is in the closed position of the bag 1.
- the latter comprises a nozzle 20 provided with at least one spur 22 on its periphery, a nozzle support 30 mounted movable by rotation on the frame 13 and comprising on the one hand at least one slot 31 in which the spur 22 moves and on the other hand a finger 32 cooperating with the drive means 10 of the control member 11, said spur 22 extending outwards from the slot 31 to bear on a stop system 15 in the form of a two-level staircase 16, 17 to guide the locking of the nozzle 20 on the frame 13 using four separate positions for the spur 22.
- the drive means 10 cooperates with the finger 32 by means of a cam 10b, shown in FIG. 4 and arranged integrally on said drive means 10.
- the cam 10b is arranged on the drive means 10 in the free space situated between the frame 13 and the rigid zone 1a.
- the finger 32 causes the cam 10b to tilt during rotation of the nozzle 20 corresponding either to a shutter or to an opening of the bag 1 by the shutter means.
- FIG. 3a shows the nozzle support 30, provided with the slot 31 in which the spur 22 moves and the finger 32 driving the control member 11.
- FIG. 3b represents the stop system 15 having two distinct levels 16 and 17 allowing the nozzle 20 to occupy successively several positions during the positioning of said nozzle 20 on the nozzle support 30.
- the first position corresponds to a support of the spur 22 on the first level 16 of the stop system 15 after a first depression of the nozzle 20, the second position corresponding to a positioning of the spur 22 beyond the first level 16 after a first rotation RI in the extension plane of the first level 16, the third position corresponding to a support of the spur 22 on the second level 17 after a second depression E2, the fourth position corresponding to the locking of the spur 22 on the frame 13 after a second rotation R2 in the extension plane of the second level 17.
- the stop system 15 integral with the frame 13 and extending in the vicinity of the periphery of the nozzle support 30, has levels 16 and 17 sufficiently extended along an internal periphery 19 of the frame 13 so as to pe rmit successively the opening of the bag 1 during the first rotation RI and the locking of the nozzle 20 on the frame 13 during the second rotation R2. Furthermore, the first recess E1 accommodates the spur 22 in the slot 31 and the second recess E2 corresponds to the introduction of the nozzle 20 into the bag 1 so as to pass through the sealing membrane 3.
- FIG. 3c represents the functional diagram of the positioning of the nozzle 20 on the frame 13. By diagramming the four successive stages of the locking including the first recess El, the first rotation RI, the second recess E2 as well as the second rotation R2 .
- the device according to the invention comprises a boss 18 arranged on the frame 13 opposite the second level 17 of the stop 15, said spur 22 is housed between the boss 18 and the second level 17 in the position for locking the nozzle 20 on the frame 13.
- the nozzle 20 cannot be separated from the frame 13.
- the unlocking or detaching of the nozzle 20 from the frame 13 is carried out in reverse to locking by releasing the spur 22 from the boss 18 against which the spur 22 bears in the locked position.
- the cooperation means make it possible to automatically activate the opening and closing of the bag 1 respectively with the locking and unlocking operation of the nozzle 20 on the frame 13.
- the clearance 11b opens onto a free space in which moves a rod not shown in the figures and secured to the nozzle support 30 after the second recess E2.
- a face of the control member 11 overhangs and achieves a stop for the rod when the user exerts pressure on the control member 11 when the nozzle 20 is locked on the frame 13 corresponding to a position d an opening of the means for closing the bag 1. The latter cannot then be separated from the frame 13.
- additional support can be provided on the frame 13 preventing any translation of the control member 11 when the means for closing the bag 1 is in the open position.
- the boss 18 is replaced by a ramp inclined with respect to the horizontal and arranged on the internal periphery 19 of the frame 13.
- the stop 15 consists of a profiled groove made in the frame 13.
- the spur 22 is thus moves in the profiled groove and cannot in any way be released from said profiled groove as long as it is not in the first position corresponding to the first depression E1.
- the device thus designed prohibits the nozzle 20 from detaching from the frame 13 as long as the means or flap 5 for closing the bag 1 is not in the closed position.
- the frame 13 comprises a second stop 15 symmetrical with respect to the first to ensure better stability of the locked assembly, which consists of the nozzle 20 and the frame 13.
- the stop system 15 corresponds to a bayonet type system
- Figures 2, 3, 3a, 3b, 3c and 4 thus schematize a connection device between a suction unit and a suction pipe, consisting of the nozzle 20, means for locking the nozzle 20 on the frame 13 as well as cooperation means allowing the nozzle 20 to cooperate with the control member 11, so that the locking of said nozzle 20 is possible as soon as the flap 5 is in its open position.
- the user begins by fixing the bag 1 inside the frame 13 via the flange 14 and the groove
- the user then rotates the control member 11 so as to position the flap 5 in its open position.
- the nozzle 20 can then be fixed, on the frame 13.
- the user separates the nozzle 20 from the frame 13, turns the shutter 5 to its closed position using the control 11 and separates the part of the frame 13 on which the bag 1 is fixed from the rest of the suction unit.
- the user can then separate the bag 1 from the part of the removable frame 13, for example above a trash can, by a simple pressure on the member 11
- the user fixes the bag 1 initially closed, for example, on the frame 13.
- the flap 5 of the bag 1 is automatically in its closed position.
- the control member 11 is then used only to separate the rigid part la from said frame 13, by a translational movement of the control member 11.
- a simplification could in this case be envisaged, and which would consist in using the means d 'drive 10, associated with the cam 10b, as a control member 11 inside the frame 13. The user should then separate the bag 1 from the frame 13 by his own means and in particular by twisting the rigid zone 1a.
- An advantage of the device according to the invention lies in obtaining an automatic closure of the bag 1 by unlocking the nozzle 20 or by actuating the control member 11 directly by the user.
- Another advantage of the device according to the invention is obtained by the absence of direct contact between the user and the bag 1 filled with dust after use of the vacuum cleaner.
- the ejection is done by simple pressure on the control member 11.
- An additional advantage of the bag 1 according to the invention lies in the production of a closure system, comprising a flap 5 pivoting on the one hand and devoid of a rotation axis for said flap 5.
- the invention finds its industrial application in the field of dust vacuum cleaners.
