    Technical area
    The present invention relates to the field of vacuum cleaners equipped with a suction head for sucking dust and small particle size waste present on a surface. The invention aims to design a suction head easily adaptable according to the nature of the surface to be sucked.
    State of the art
    Vacuums equipped with a suction head are well known on the market, these making it possible to clean surfaces by suction for the evacuation of dust and small particle size waste resting thereon.
    The surface to be vacuumed can be for example tiles, parquet, laminate, carpet or a carpet. It is therefore necessary to be able to best adapt the suction head sweeping the surface as a function of the nature thereof.
    The suction head traditionally comprises a connection sleeve and a sole, which comprises a lower face with a cavity extending transversely on the head, said cavity communicating with said sleeve by means of a rigid or flexible conduit. The underside of the soleplate is positioned adjacent to the surface to be vacuumed during use of the suction head.
    It is known from the documents FR2442617A1, FR2439577, FR2967042A1, EP3047776 and CN205585956 allowing adaptation of the suction head according to the nature of the surface to be vacuumed.
    In patent application FR2442617A1, the suction head comprises a set of two brushes arranged at the front and at the rear of the sole, each on one side of the cavity. A mechanism actuated by a joystick makes it possible to define three positions of the set of two brushes. According to a first position of the handle, favorable for use on long pile carpet, the mechanism raises the brushes back with respect to the underside of the sole which thus rests on the suctioned surface. According to a second position of the handle, favorable for use on hard floors, the mechanism descends the brushes projecting from said lower face which is thus detached from the suctioned surface, the brushes being in contact with said surface. According to a third position of the handle, favorable for use on compact or short-pile carpet, the mechanism inclines the set of brushes relative to said underside, the rear brush being projecting from that -this and the brush back before.
    In patent application FR2439577A1, the sole and the connection sleeve of the suction head communicate with each other by means of a rigid fork-shaped tube. The tube is articulated, on the one hand, with the sleeve at the axis of the support wheels on the surface to be vacuumed and, on the other hand, with the soleplate at the level of an axis parallel to the axis wheels. The suction head comprises a mechanism actuated by a lever, making it possible to project or withdraw a set of two brushes vis-à-vis the underside of the soleplate, by lowering or raising it. One of the brushes is located at the front of the sole and the other at the rear, each on one side of the cavity.
    In patent application FR2967042, the sole and the connection sleeve of the suction head are connected by means of a connecting rod mounted in pivot connection, on the one hand, with the sole on a first axis and, d on the other hand, with the sleeve along a second axis, said axes being parallel to each other and with the axis of rotation of support wheels on the surface to be vacuumed. The sole includes two angular stops and the connecting rod comprises at its front end an arm which comes into contact against the angular stops when it pivots up or down the sole relative to the connecting rod. The sole comprises on its underside two edges disposed respectively in front and at the rear of the cavity. During a forward movement of the suction head, the arm comes into contact with the upper angular stop, which brings the front edge into contact with the surface to be suctioned while the rear edge is slightly detached from this area. Conversely, during a backward movement of the suction head, the arm comes into contact against the lower angular stop, which brings the rear edge into contact with the surface to be suctioned while the front edge is slightly detached from this surface. The contact of an edge with said surface makes it possible to scrape it and, conversely, the detachment of the edge with respect to it allows a flow of air to enter the cavity.
    In patent application EP3047776A1, the soleplate and the connection sleeve of the suction head are connected by means of an articulation allowing angular movement between said parts. Casters are attached to the back of the sleeve. When the suction head is pushed forward, the rollers are lifted from the surface to be vacuumed and vice versa when the said head is pulled back. A mechanism actuated by a lever makes it possible to raise or lower two brushes arranged respectively at the front and at the rear of the cavity, so that they are protruding or recessed with respect to the underside of the sole in depending on the nature of the surface.
    In application CN205585956, the sole and the connection sleeve of the suction head are connected by means of a coupling part allowing an angular movement between said parts. The coupling piece is pivotally connected to the sole and includes a light receiving a pin arranged on the sleeve, which pivots in this light and slides along it. A mechanism actuated by a joystick makes it possible to raise or lower a brush inside the sole according to the nature of the soil to be vacuumed.
    Summary of the invention
    The aim of the present invention is to design a suction head which makes it possible to adapt as best as possible to the nature of the surface to be suctioned, the adaptation being made by the action of a single lever in order to facilitate the use of the vacuum cleaner and the display of the position of use.
    To this end, the invention relates to a suction head for a vacuum cleaner which comprises:
    - a sole provided with a lower face and a cavity opening onto this lower face;
    - at least one brush which extends transversely over the sole;
    - a connection sleeve configured to communicate with the cavity via a flexible tube;
    - a fork arranged between the sole and the sleeve and mounted in pivot connections of transverse axes with respect to said sole and said sleeve.
    Furthermore, according to the invention, the suction head comprises a mechanism and a handle, said handle being configured to actuate said mechanism in three positions, said mechanism being configured for:
    - in the first position, lower the at least one brush and position it protruding on the underside, allowing the fork to pivot relative to the sole;
    - in the second position, mount the at least one brush and position it back from the underside, allowing the fork to pivot relative to the sole;
    - in the third position, keep at least one brush set back from the underside by blocking the fork vis-à-vis the sole.
    The first position is favorable for use on smooth floors such as a tiled, parquet or laminate surface. The second position is favorable for use on carpets or rugs. The third position advantageously makes it possible to force the sole to tilt in a position favoring the scraping of the surface to be vacuumed. These different positions are obtained simply by actuating the lever, which greatly facilitates the use of the suction head.
    In an embodiment of the suction head according to the invention, the mechanism comprises two angular stops configured to approach one towards the other when the lever is actuated from the first position to the third position, and vice versa to deviate during the actuation of the lever from the third position to the first position. In a preferred embodiment, a low angular stop will be fixed and a high angular stop will be mobile, but a mechanism could be envisaged on which the high and low angular stops are both mobile and approach each other. The purpose of these angular stops is to limit the pivoting of the fork relative to the sole, until reaching the blocking between the fork and the sole in the third position of the lever.
    In an embodiment of the suction head according to the invention, the mechanism is configured so that, in the third position of the lever, the blocking of the fork stops the latter in the tilted position towards the front with respect to the sole, which tends to lift the fork and the sleeve relative to the sole. In addition, the fork is configured to ballast the sole, in particular due to the lifting of the latter and of the sleeve with respect to the sole, which forces the inclination towards the rear of said sole due to the wedging. , thus positioning it in a preferred position for scraping the surface to be vacuumed. Preferably, this tilt is carried out at an angle of seven to ten degrees, preferably eight to nine degrees.
    In one embodiment of the suction head according to the invention, the mechanism is configured so that, in the second position of the handle, the pivoting of the fork is limited when it is tilted backwards. This limitation of the pivoting and the ballasting generated by the configuration of the sole and of the sleeve also force the inclination towards the rear of the sole. Preferably, this inclination is carried out at an angle of one to three degrees, preferably two degrees.
    According to the suction head object of the invention, a pivot link of transverse axis is arranged between the handle and the sole, this handle being preferably arranged on the top of the sole to facilitate its accessibility with the foot or the hand. In addition, the mechanism comprises at least one upper abutment part and means for securing the abutment part to the lever, the fork comprising at least one bearing part arranged to come into contact against the at least one part. upper stop when tilting towards the rear of the fork. Preferably, two upper stop pieces are distributed over the lateral parts of the suction head and two support pieces are arranged in correspondence with said stop pieces.
    According to the suction head that is the subject of the invention, the mechanism comprises at least one bottom stop piece, the fork comprising at least one support piece arranged to come into contact against the at least one bottom stop piece during tilting the fork forward. Preferably, two lower stop pieces are distributed over the lateral parts of the suction head and two support pieces are arranged in correspondence with said stop pieces. Preferably, the at least one bottom stop piece is implemented directly by the upper part of the sole, the at least one support piece of the fork coming into contact against the latter.
    According to the suction head object of the invention, a pivot link of transverse axis is arranged between the lever and the sole, the same as that defined above. In addition, the mechanism includes:
    - at least one transmission tab provided with a light and means for securing said transmission tab to the lever;
    - at least one connecting rod provided with an upper part receiving a pin which is housed in said lumen;
    - A support part of the at least one brush, said part being mounted in slide connection on the sole along an axis perpendicular to the underside of said sole, the connecting rod being provided with a lower part pivotally mounted vis-à-vis -vis of said support piece.
    According to the suction head object of the invention, it comprises a system for stopping the lever and the mechanism according to the three positions.
    In an embodiment of the suction head, a pivot link of transverse axis is arranged between the lever and the sole, the same as that defined above. In addition, the aforementioned shutdown system includes:
    - A stop tab and means for securing said stop tab to the lever, the stop tab comprising a lug mounted flexible in particular thanks to the flexibility of this tab;
    a circular groove arranged on the sole in which the lug is housed, said groove comprising an orifice configured to receive the lug in the second position of the lever, said lug abutting against the ends of the groove in the first and third position of the joystick.
    In an embodiment of the suction head, the stop system comprises, in addition, or as a variant, at least one protuberance on the sole and at least one abutment plate coming into contact with said protuberance when returning to the first position of the lever and mechanism. This ensures that the brushes stop properly in the projecting position vis-à-vis the underside of the soleplate.
    According to the suction head object of the invention, return means are configured to participate in the ascent of the at least one brush during the movement of the lever from the first position to the second position.
    In a preferred embodiment, the suction head comprises two brushes arranged respectively on the front side and on the rear side of the sole, each on one side of the cavity.
    According to the suction head object of the invention, the underside of the sole includes a front part and a rear part, the rear part being inclined upwards with respect to the front part. Thus, when the sole is in the normal position, the front part is more or less parallel to the surface to be vacuumed and when the sole is tilted backwards, in the third position, the edge between the front part and the rear part is in contact with said surface. Preferably, the cavity is located in the front part, the rear edge of the cavity corresponding with the edge defined between said front and rear parts.
    According to the invention, the suction head comprises at least one wheel arranged in the pivot axis between the fork and the sleeve, preferably two wheels. One could consider slightly shifting the axis of the at least one wheel opposite the pivot axis between the fork and the sleeve, depending on the shapes of the elements of said suction head.
    The invention also relates to a vacuum cleaner equipped with a suction head comprising one and / or the other of the above characteristics. The sleeve will be connected to a suction system by means of a rigid or flexible tube, or even directly to said suction system.

    detailed description
    As illustrated for example in FIGS. 1 to 3, the suction head 1 comprises a connection sleeve, referred to as sleeve 2 in the rest of the description, at the end 2a of which is connected a tip of a rigid tube or flexible, itself connected to the vacuum system of the vacuum cleaner (not illustrated). Various variants of vacuum cleaners already exist on the market and can be used with the suction head 1 according to the invention; these being known to a person skilled in the art, they are not detailed in the present patent application.
    The suction head 1 comprises a fork 3 and two wheels 4a-4b, illustrated for example in FIG. 12. The sleeve 2 is mounted in pivot connection with respect to the fork 3 along a transverse axis X1 preferably corresponding with the axis of rotation of the wheels 4a-4b each disposed on one side of the fork 3 and of the sleeve 2. However, it is possible to provide variants of suction head 1 according to the invention with a slight offset from the axis of rotation of the wheels 4a-4b downwards and / or rearwards with respect to the pivot axis X1 between the fork 3 and the sleeve 2.
    The suction head 1 comprises a sole 5, illustrated for example in FIGS. 8 and 18. The fork 3 is mounted in pivot connection with respect to the sole 5 along a transverse axis X2. For this, the fork 3 comprises two branches 6 and 7. It can be seen in FIG. 12 that an external lateral part 6a of the first branch 6 comprises an orifice 8; such an orifice is also present on the external lateral part 7a of the second branch 7, although it is not visible. These orifices 8 on the arms 6 and 7 pivotally receive two studs 9a-9b, illustrated in FIG. 18, arranged opposite two internal parts 5a5b at the rear of the sole 5.
    Thus, the sleeve 2 can tilt backwards or forwards with respect to the fork 3, as illustrated respectively by the arrows 10a and 10b in FIG. 1, and the fork 3 can also tilt backwards or forwardly relative to the sole 5, as shown respectively by arrows 11a and 11b in FIG. 2.
    The suction head 1 comprises a support piece 12 illustrated for example in FIG. 13 on which are mounted two brushes 13-14. These brushes 13-14 are positioned respectively on the front side 5c and on the rear side 5d of the sole 5 when said support piece 12 is mounted on said sole 5, as illustrated for example in FIGS. 1 and 20. The support piece 12 is mounted in slide connection on the sole 5 along an axis X3 disposed perpendicularly to the front part 15a of the lower face 15 of the sole 5, as illustrated in FIG. 1. When the sole 5 lies flat on the surface to suck, without any constraint, this axis X3 is more or less vertical. The support piece 12 comprises two guide slots 16a-16b, illustrated in FIG. 13, which respectively receive two complementary guide elements 17a-17b arranged on the upper side of the sole 5 as illustrated in FIGS. 8 and 18. Similarly, the support piece 12 comprises two guide holes 18a-18b which receive two guide rods 19a-19b arranged on the upper side of the sole 5. The axis X3 of translation between the support piece 12 and the sole 5 is also materialized in FIGS. 8 and 13.
    The suction head 1 comprises a handle 20 which actuates a mechanism 21, an overall view of which appears in FIGS. 1 to 7. The handle 20 is mounted in pivot connection relative to the sole 5 along a transverse axis X4, which allows its pivoting according to the three positions and the movement of said mechanism 21 according to three different positions.
    The mechanism 21 comprises two parts 22-23 each disposed on a lateral side of the sole 5, as illustrated for example in FIGS. 4 to 7. The mechanism 21 acts on the support part 12 and on the fork 3 by moving the two parts 22-23 and transmission parts when the position of the lever 20 is changed, as detailed below.
    As illustrated in FIG. 11, the first part 22 integrates the lever 20 and includes a first housing 24 at an angle and a second semi-cylindrical housing 25. These first and second housings 24-25 receive a first angled end 26a of a transmission bar 26, illustrated in FIG. 5, which makes it possible to subject the lever 20 to this transmission bar 26. This assembly appears for example in FIG. 19.
    As illustrated for example in FIG. 8, the sole 5 comprises seven rolling bearings 27a-27g, two of which 27b and 27f are arranged at the upper ends of the guide rods 19a-19b and the other five (27a, 27c-27e and 27g ) are arranged respectively at the ends of five extension tabs 2832. These rolling bearings 27a-27g define the axis X4 and receive in rotation the transmission bar 26, as illustrated for example in FIG. 4.
    As illustrated in FIG. 9, the second part 23 also includes a first housing 33 in a square and a second semi-cylindrical housing 34 which receive a second square end 26b of the transmission bar 26, illustrated in FIG. 15, which makes it possible to subject said second part 23 to the transmission bar 26 and, consequently, to the first part 22 integrating the lever 20. This assembly appears for example in FIG. 19.
    Thus, manipulation of the lever 20 makes it possible to concomitantly pivot the transmission bar 26 and the two parts 22-23 around the axis X4.
    The first part 22 comprises a transmission lug 35 which is provided with a light 36, as illustrated in FIG. 11. Likewise, the second part 23 comprises a transmission lug 37 provided with a light 38, as illustrated in FIGS. 9 and 10. These two transmission lugs 35 and 37 are arranged opposite each other at the two angled ends 26a-26b of the transmission bar 26, on the lateral sides of the sole 5, as illustrated for example in FIG. 19.
    As illustrated for example in Figures 13, 14 and 16, the support piece 12 comprises on its lateral sides 12a-12b two housings 39a-39b each receiving pivotally, along a transverse axis X5, a first part 40a of a connecting rod 40 held in pivot connection by means of a connecting pin 41. In FIG. 13, only one of the connecting rods 40 is shown on the lateral side 12b of the support piece 12 so as to leave visible the housing 39a and the connecting axis 41 on the other side 12a; it goes without saying that the connecting rod 40 will be positioned in this housing 39a before the establishment of the connecting pin 41.
    As illustrated in FIG. 16, each connecting rod 40 comprises on its second part 40b a slot 42 in which is housed the transmission tab 35 of the first part 22 on the lateral side 12b of the support part 12 and, likewise , in which is housed the transmission lug 37 of the second part 23 on the lateral side 12a of said support part 12. A pin 43, illustrated in FIG. 14, is housed in the hole 44 on the second part 40b of the connecting rod 40 and in the light 36 of the transmission lug 35 on the first part 22, likewise in the light 38 of the transmission lug 37 on the second part 23. Thus the second parts 40b of the connecting rods 40 can pivot and slide in the respective lights 36 and 38.
    As illustrated with reference to FIGS. 8, 13 and 18, the support piece 12 comprises two hollow cylindrical portions 45a-45b respectively having the guide holes 18a-18b, inside which springs are housed (not shown). ) which receive the guide rods 19a-19b and which bear on cross-pieces 46a-46b arranged on the upper side of the sole 5, which forces the support piece 12 upwardly against the sole 5 when nothing retains said support piece 12.
    In the first position of the lever 20 and of the mechanism 21, illustrated in FIGS. 1, 4 and 5, the transmission lugs 35 and 37 make it possible, by means of the connecting rods 40, to translate the support piece 12 downwards relative to the sole 5, which makes it possible to take out the brushes 13-14 and to arrange them projecting with respect to the lower face 15. The brushes 13-14 can rest on the surface S to be vacuumed and the lower face 15 of the sole 5 remains detached from said surface S.
    In the second position of the lever 20 and of the mechanism 21, illustrated in FIGS. 2 and 6, the transmission lugs 35 and 37 pivot, which moves the lights 36 and 38 upwards and backwards as illustrated in FIG. 2. In this position the connecting rods 40 would tend to remain in the position illustrated in FIG. 1, that is to say at the first ends 36a and 38a of the lights 36 and 38 on the transmission lugs 35 and 37. However, the presence of aforementioned springs (not shown) forces the support piece 12 to go back up and the connecting rods 40 to be positioned as illustrated in FIG. 2, that is to say reassembled at the second ends 36b and 38b of said lights 36 and 38. In this second position, the brushes 13-14 are set back from the lower face 15 of the sole 5, the lower face 15 resting on the surface S to be vacuumed.
    In the third position of the lever 20 and of the mechanism 21, illustrated in FIGS. 3 and 7, the transmission lugs 35 and 37 continue to pivot backwards and upwards and the connecting rods 40 are positioned as illustrated in FIG. 3 , that is to say at the first ends 36a and 38a of the lights 36 and 38 on the transmission lugs 35 and 37. The support piece 12 is already raised relative to the sole 5 under the action of the springs (not shown) during the transition to the second position, the latter therefore remains in said raised position with the brushes 13-14 recessed with respect to the lower face 15 of the sole 5.
    The first part 22 comprises an abutment finger 47 which is positioned under the lever 20, as illustrated in FIG. 11. Similarly, the second part 23 comprises an abutment finger 48. The branches 6-7 of the fork 3 each include a end part 6c-7c which extends beyond the axis X2 of pivoting of said fork 3 relative to the sole 5, as illustrated in figure
    12. These end portions 6c-7c each include a support finger 49-50. The stop fingers 47-48 are disposed respectively in the fields of rotation of the support fingers 49-50.
    In the first position of the lever 20 and of the mechanism 21, illustrated in FIGS. 4 and 5, the abutment fingers 47-48 are positioned at the highest point which allows the fork 3 to tilt backwards in the direction of the arrow 11a illustrated in FIG. 2, by pivoting with respect to the sole 5, until the bearing fingers 49-50 come into contact with the stop fingers 47-48 as illustrated in FIG. 5. Conversely , the fork 3 can tilt forwards in the direction of the arrow 11b illustrated in FIG. 2, until the bearing fingers 49-50 come into contact on two abutment pieces 51-52 arranged on the upper face 53 of the sole 5.
    In the second position of the lever 20 and of the mechanism 21, illustrated in figure
    6, the stop fingers 47-48 have pivoted down relative to their position illustrated in FIGS. 4 and 5. In this FIG. 6, the fork 3 is tilted back in the direction of the arrow 11a illustrated in FIG. 2. Note that the support finger 50 on the fork 3 is in contact with the stop finger 48 on the second part 23; it is the same between the support finger 49 and the stop finger 47, this does not appear in FIG. 6 due to the presence of the lever 20. The choice of the stop position of these fingers of abutment 47-48 in the second position has the consequence of limiting more or less the rearward tilting of the fork 3 relative to the sole 5. As a result of this limitation, the wheels 4a-4b tend to lift from the surface S to be sucked, the mass of the fork 3, the wheels 4a-4b and the sleeve 2 then having the effect of ballasting the sole 5 and making it tilt backwards in the direction of the arrow 54 illustrated in FIG. 3, until the wheels 4a-4b are in contact with said surface S. The underside 15 of the sole 5 comprises a rear part 15b which is inclined upwards relative to its front part 15a; the ballasting carried out thus makes it possible to tilt the front part 15a of the sole at an angle a1 relative to the surface S, as illustrated in FIG. 2. This allows an air flow to enter the cavity 55 of the sole 5 illustrated in FIG. 20. Preferably, the stop position of the stop fingers 47 and 48 will be chosen so as to have an angle a1 of between one degree and three degrees (1 ° <a1 <3 °), preferably equal at two degrees (a1 = 2 °).
    In the third position of the lever 20 and of the mechanism 21 illustrated in the figure
    7, the stop fingers 47-48 are completely pivoted down and the support fingers 49-50 of the fork 3 are sandwiched between said stop fingers 47-48 and the stop portions 51-52 on the upper face 53 of the sole 5. Thus, the fork 3 is locked relative to the sole 5 in this position of FIG. 7. During the actuation of the lever 20 from the second position to the third position, the stop fingers 47-48 of the parts 22-23 press against the bearing fingers 49-50 of the fork 3, which forces said fork 3 to tilt forward in the direction of the arrow 11b illustrated in FIG. 2 and tends to take off the wheels 4a-4b from the surface S to be cleaned. As before, the ballasting of the sole 5 generated by the mass of the fork 3, the wheels 4a-4b and the sleeve 2 forces said sole 5 to tilt backwards in the direction of the arrow 54 illustrated in FIG. 3, this which inclines the front part 15a of the lower face 15 of this sole 5 by an angle a2 illustrated in FIG. 3. This angle a2 corresponds less to the angle of inclination of the rear part 15b relative to the front part 15a on the lower face 15, which makes it possible to bring said rear part 15b into contact with the surface S to be cleaned, as illustrated in FIG. 3. Preferably, this angle a2 is between seven degrees and ten degrees (7 ° <a1 <10 °), preferably between eight degrees and nine degrees (8 ° <a1 <9 °).
    As illustrated in FIGS. 3 and 20, in this third position, the edge 15c between the front part 15a and the rear part 15b on the underside 15 of the sole 5 makes it possible to scrape the surface S to be vacuumed. This edge 15c corresponds substantially with the rear edge 55a of the cavity 55. This cavity 55 communicates with a nozzle 56, as shown in FIG. 20, which is connected to the sleeve 2 by means of a flexible conduit 57 shown diagrammatically in dotted lines on Figure 1.
    As illustrated for example in FIGS. 9 to 11, the first part 22 comprises a stop lug 58 provided with a lug 59 and the second part 23 also includes a stop lug 60 provided with a lug 61. These pins 59 and 61 are arranged facing each other when the parts 22 and 23 are mounted on the transmission bar 26. The locking tabs 58 and 60 are flexible or flexible on the parts 22 and 23. As illustrated in FIG. 8, the extension tab 29 on the upper face 53 of the sole 5 comprises on its outer side 29a a groove 62 of circular shape. Similarly, the extension tab 31 comprises on its external side 31a a circular groove, not visible in the figures, but identical to the groove 62. These grooves 62 each comprise an orifice 63-64 positioned more or less in the central part of said grooves 62, as illustrated in FIG. 8. The pins 59 and 61 are respectively housed in the grooves 62 when the parts 22-23 are mounted on the sole 5, said pins 59 and 61 coming to bear lightly in the bottom of these grooves 62. Due to the flexibility of the stop lugs 58 and
    60, the pins 59 and 61 penetrate inside the orifices 63-64 when these correspond, which stops the position of the parts 22-23 and, consequently, that of the lever 20. The lever 20 and the mechanism are in second position in this configuration. By exerting a slight pressure on the lever 20 to move it into the first or third position, the flexibility of the stop tabs 58 and 60 allows the lugs 59 and 61 to be released outside the orifices 63-64, thus allowing actuation of the mechanism 21 and of the lever 20. The pins 59 and 61 then move in the respective grooves 62 until they come, in one direction, into abutment against the first ends 62a of said grooves 62 where the lever 20 and the mechanism 21 have reaches the first position or, in the other direction, in abutment against the second ends 62b of said grooves 62 where the lever 20 and the mechanism 21 have reached the third position.
    As illustrated in FIGS. 10 and 11, the parts 22-23 each include a stop plate 65-66. As illustrated in Figures 4 and 8, the extension tabs 28 and 32 on the sole 5 include on their outer sides 28a and 32a protrusions 67-68. In the first position of the lever 20 and of the mechanism 21, the abutment plates 65-66 respectively come to bear on these protrusions 68-67, as illustrated in FIGS. 4 and 5. This makes it possible to precisely stop the lever 20 and the mechanism 21 by resisting greater forces, the handle 20 being frequently manipulated with the foot by the user. These abutment plates 65-66 and protrusions 68-67 ensure an adequate distribution of the forces over the width of the sole 5, in association with the grooves 62 and lugs 59 and 61, when the lever 20 returns to the first position.
    As illustrated in FIG. 9, the second part 23 comprises a tab 69 provided with a protuberance 70 on its external side 69a, said protuberance 70 coming to bear against the internal side 28b of the extension tab 28 on the sole 5 , as illustrated in FIG. 7. This makes it possible to wedge said piece 23 on the sole 5 while keeping the lug 61 properly supported in the groove 62.
    The suction head 1 also comprises a stop piece 71 illustrated in FIG. 17, which is fixed to the sole 5 and which comprises a groove 72 in which the rear brush 14 is housed, as illustrated in FIG. 19. As described previously, in the first position of the lever 20, the bearing fingers 4950 on the fork 3 come against the abutment fingers 47-48 on the parts 2223, which defines and stops the tilted position towards the rear of said fork 3 vis-à-vis the sole 5. One could however envisage in a variant that the stopping of the fork 3 in the tilted position is achieved by the stop piece 71, in which case the lower faces 6b-7b of the branches 6-7 of the fork 3, illustrated in FIG. 12, would come into abutment against the upper face 71a of said stop piece 71, as can be imagined with regard to FIG. 19.
    One could also envisage a sufficient clearance of said abutment fingers 47-48 with respect to said bearing fingers 49-50 so as not to limit the tilting of the fork 3 towards the rear towards the sole 5 , in the second position of the lever 20, in order to keep the front part 15a of the lower face 15 of this sole 5 flat on the surface S to be sucked up, in this second position.
    Variants of implementation are possible without departing from the scope of the invention.
