Definitions

the present invention relates to a dust suction nozzle, and more particularly to an improvement of the waste collection efficiency.
Vacuum suckers are waste collection devices that contaminate the surface to be cleaned. They are therefore the object of many improvements aimed in particular to improve such collection.
Patent FR 2773456 in the name of the Applicant has the advantage of having a frontal orifice in the tip of the nozzle, to suck the waste slightly in front of the nozzle, which, in addition to the appropriate tapered form of the nozzle, allows in particular to easily reach the nooks and crannies of the parts to be cleaned.
a nozzle according to this patent, is devoid of retractable brushes.
Such brushes are found in other documents, in particular US Pat. No. 2,394,798, where the edge of the soleplate of the nozzle comprises two brushes disposed inside the edges forming the tip of the triangular nozzle and partly delimiting the central opening of the nozzle. suction. These brushes, however, are fixed and allow to brush the surface to be cleaned followed by suction only when the nozzle is moved forward.
the suction nozzle of triangular shape comprises two suction channels arranged along the edges forming the tip of the nozzle. These channels are each lined, in the inner part of the nozzle, by a fixed brush. Such brushes can not retract depending on the nature of the soil to be treated. In addition, the brushing of the soil to be treated is immediately followed by suction only when the nozzle is moved backwards.
the present invention aims at overcoming the disadvantages of the prior art by presenting a triangular nozzle with improved performance in terms of presenting in particular a multiplicity of brushes, which can be retracted by a simple device to keep a compact shape to the nozzle.
the present invention is achieved with the aid of a suction nozzle of substantially triangular shape having in particular two side edges forming the tip of the nozzle, said nozzle being open to the surface to be cleaned by at least two suction channels arranged in the sole of the nozzle and arranged along the two side edges forming the tip of the nozzle, characterized in that each suction channel is bordered by a front brush and a rear brush, said brushes being located on either side of the channel extending substantially parallel to the latter.
the nozzle is of isosceles shape having a rear edge joining the lateral edges, and in that the two channels arranged along the lateral edges meet in the front part of the nozzle.
Such a configuration allows greater stability of the nozzle facilitating its movement. Furthermore, the junction of the two channels in the front part of the nozzle simplifies somewhat the design and manufacture of the nozzle since the common area is open at the level of the sole of the nozzle.
the brushes can occupy two positions: a position where they are protruding relative to the sole of the nozzle and a position where they are slightly set back from said soleplate, the two positions being controlled by a mechanism actuated by a pedal located at the level of the nozzle cover.
This embodiment makes it possible to obtain different contact surfaces according to the soils to be treated and / or the actions envisaged. It is indeed interesting to occasionally have brushes for soliciting the surface of the soil to be treated, for example carpet, in order to extract the waste attached to the fibers. The output and retraction of the brushes are facilitated by a pedal that can be actuated by the foot being disposed on the cover of the nozzle.
the pedal is advantageously mounted in rotation on the soleplate of the nozzle, the rod being linked, on the one hand to the pedal by a portion parallel to the axis of rotation of the pedal, and on the other hand to the carriages by portions substantially perpendicular to the axis of rotation of the pedal, so that such a rotation of the pedal causes a horizontal movement of the carriages.
the rockers and trolleys are symmetrical with respect to a median vertical plane to the nozzle, which allows to evenly distribute the forces on each sub-assembly formed by a carriage, a rocker, a front brush and a rear brush. This symmetry ensures uniform movement of the different brushes.
the brushes at the rear of the channels meet at the junction of the two side channels forming an inverted V.
this rear brush extending sinuating from one edge to the other of the nozzle allows, when the brushes are out, a good stability of the nozzle on the floor to be treated without the risk of tilting forward or towards the back the nozzle during his travels.
the nozzle remains well flat on the floor to clean.
each rocker comprises the points of support of one of the front brushes and a portion of the support points of the rear brush.
the front edge of the nozzle has at least one front orifice intended to ensure suction in a direction substantially parallel to the surface to be cleaned, said front suction orifice being connected to one of the suction channels.
the present invention relates to a vacuum nozzle 1.
a vacuum nozzle 1 has a connection tube 2 connecting to a vacuum cleaner body, not shown, including a motor-fan capable of creating an air intake flow.
the connecting tube 2 opens at the sole 11 of the nozzle in contact with the soil 4 to be cleaned, via connecting conduits 3. These conduits open on the suction channels. These channels are generally configured according to the shape of the nozzle, in order to optimize the suction efficiency. In the example presented in which the nozzle is of triangular shape, the suction channels, as represented by the dots 10, extend in part along the two edges 5, 6 forming the tip of the nozzle, as well as in said tip of the nozzle after joining in the central part of the nozzle.
the angular zone forming the tip of the nozzle comprises a front orifice 7 intended to provide suction in a direction substantially parallel to the surface to be cleaned.
the nozzle has retractable brushes actuated by a pedal 8 pivoting.
This pedal 8 is accessible at the hood 12 of the nozzle.
the latter in this embodiment, has essentially only aesthetic functions and environmental protection.
the suction channels are closed on the one hand by an internal structure made in part during the manufacture by molding of the sole, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also by an upper part 14 which, according to the embodiment, is a viewing area made by making transparent the triangular piece attached to the sole.
this viewing area may cover a larger field than that of the suction channel, in order to adjust the target of the waste to be extracted from the ground.
the viewing area has a magnifying effect, having a convex shape.
the waste under the viewing area is magnified, improving the visualization of the surface to be cleaned.
Figure 2 shows the nozzle seen from below.
the sole 11 of the nozzle has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a channel 20 substantially parallel to the edge 5 of the nozzle. These channels meet in the central region 21 of the nozzle.
the channels 19 and 20 have front openings, that is to say in the vertical flanges of the sole, respectively 36 and 35, allowing a lateral suction substantially parallel to the surface to be cleaned.
the triangular shape is completed, at the rear of the nozzle, by a solid portion 40 having two locations 42 of means promoting the displacement of the nozzle, which may be either PTFE-type pads or wheels, such as visible wheels 43 in Figure 9.
the nozzle also comprises a blade 23 extending in the region 21, from the edge 5 of the nozzle to the edge 6, thus defining a front channel 18 and a rear channel 22, the front channel 18 opening at the tip of the nozzle by the front opening 7.
This blade 23 has a zone 24 where is disposed a pull-wire fabric as it is known per se.
This blade 23 connects the edge 5 to the edge 6 as a bridge, providing a space between the face opposite the zone 24 and the upper part 14. This blade is preferably parallel to the rear edge 9 of the nozzle.
a second zone 124 carrying a pull-out fabric may be provided on a border of the channel 22, symmetrically to the zone 24 carrying the pull-son.
the channels 19 and 20 each have scraping blades 46 and 45 extending respectively from the edge 6 and the edge 5 towards the other edge in the suction channel.
these blades are fixed and issuing from the bottom plate of the nozzle, extending substantially parallel to the rear edge 9 over a distance close to half the width of the channel.
these blades are not or are not prominent relative to the bottom plate of the nozzle.
the nozzle comprises brushes 55, 56, 57, said brushes being retractable through the sole.
the brush 55 is disposed between the suction channel 20 and the edge 5, while the brush 56 is disposed between the suction channel 19 and the edge 6.
the channels 19 and 20 joining at the front of the nozzle forming an inverted V, the rear brush 57 follows this shape along the border defined by the two channels and their meeting.
the rear brush has in particular a notch 157 in the middle of the brush, ie in the cup shape of said brush, in order to facilitate the suction of the waste that can be housed in this form of the brush at the moment of the movement towards the rear of the nozzle.
Figures 3, 4 and 5 represent, in isolation, the brushes and the output control mechanism of said brushes.
a remarkable fact of the device is, in addition to the arrangement of the pedal, its perfect symmetry with respect to a vertical median plane and perpendicular to the nozzle.
the pedal 8 comprises a lateral pin 81 for its connection with the sole of the nozzle, via a vertical piece 82, visible in Figure 9 and having a hole in which is housed said pin.
the stud thus housed in the piece 82 constitutes a pivot axis of the pedal.
the latter also has a hollow extension 83.
the pedal 8 is linked to a rigid rod 28 of motion transmission, this rod being fixed to the pedal in the extension of the axis of rotation of the pedal, ie in the extension of the pin 81, as shown in FIG. 4.
This rod comprises several elbows constituting a specific shape whose particularity is to remain flat by constituting in particular a horizontal part 280 which is the part of connection with the pedal, and two substantially vertical parts 282. These are located at each end of the rod and are each connected with a carriage 85, 86.
the vertical portion 282 located under the pedal 8 passes into the hollow portion of the extension 83 of the pedal which thus constitutes a guide of the rod and ensures the transmission of the force to the rod.
the rod 28 is also supported by two vertical supports 128 from the sole.
the carriages 85, 86 are two identical L-shaped pieces having a rather long horizontal portion directed forwardly of the nozzle and a shorter vertical portion directed downwardly. These carriages are secured between the sole of the squeegee and the hood so as to be able to move only horizontally, towards the front or towards the rear of the squeegee. Two arches 194 from the sole and through which are mounted the carriages 85, 86, in particular allow to prohibit any vertical movement of said carriages.
Each carriage 85, 86 has, at the front end of their horizontal portion, a beveled shape, respectively 185, 186.
These portions Bevels constitute cam surfaces capable of interacting with parts 125, 126 beveled identically in independent parts 75, 76 in correspondence called rockers, during the horizontal displacement of said carriages.
the beveled portions 125, 126 open at their upper part, on a substantially horizontal flat portion respectively 25, 26.
each carriage 85, 86 is capable of interacting respectively with the rocker 75 and the rocker 76.
the rockers are substantially flat parts which are mounted in the nozzle having a degree of freedom in a vertical direction, being maintained in their horizontal clearance essentially by the sole of the nozzle, for example using slide pins 192 from the sole and on which can slide the rockers through openings 175, 176 in correspondence of the pins 192.
each piece or some of them may be provided with gaudrons or small vertical bulges to facilitate the vertical translation of the rockers.
the sole will also be equipped with gaudrons under each carriage for maintaining the carriages in the brushes output position in order to avoid the inadvertent triggering of the mechanism.
a spring 165, 166 is mounted between each rocker 75, 76 and the sole of the nozzle.
Each rocker comprises housings 65, 66 for the brushes 55, 56, each brush being held in the housing, essentially by resilient clamps of the clip type 95, 96. Furthermore, the downward stop of the rockers is provided by zones of stopping the vertical downward movement of the rockers, constituted by the periphery of the housing of the brushes. The contact thus created with matching parts of the sole of the nozzle ensures a good seal.
the rear brush 57 is maintained for half by each rocker, to using the clips 97, 98, and, as for the brushes 55, 56, the downward stop of the rockers at the exit of the brushes is achieved by the contact between the periphery of the housing of the brushes and the sole.
the substantially vertical portions 282 also pivot, causing a forward displacement of the carriages 85, 86 linked to the ends 282 of said rod.
This advance of the carriages causes the cooperation of the bevelled parts of the carriages with those of the rockers.
the latter under the forward movement of the carriages, undergo a vertical downward movement against the restoring force of the springs 165 , 166, the play of the slopes sliding the rockers 75, 76 under the carriages 85, 86, the latter bearing respectively on the plane portions 25, 26.
the rear brush 57 can be reduced to two distinct rectilinear portions, each simply held by their respective rocker.
