Definitions
- 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.
- 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 bottom face with a cavity extending transversely on the head, said cavity communicating with said sleeve via 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.
- 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 activated 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.
- the sole and the connecting 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 arranged at the front of the sole and the other at the rear, each on one side of the cavity.
- 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, 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 during a pivoting up or down of the sole relative to the connecting rod.
- the sole comprises on its underside two edges disposed respectively at the front and at the rear of the cavity.
- 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 surface.
- 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 sole and the connection sleeve of the suction head are connected by means of a coupling part allowing an angular clearance between said parts.
- the coupling part is in pivot connection relative to the sole and comprises 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.
- the document EP 2,687,139 A2 describes a vacuum cleaner suction head according to the preamble of claim 1 comprising a mechanism and a handle, said handle being configured to actuate said mechanism in two positions.
- the object 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.
- 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.
- 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 move during the actuation of the lever from the third position to the first position.
- a low angular stop will be fixed and a stop high angle will be mobile, but one could consider a mechanism 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.
- 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.
- 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.

- 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 lightly bear in the bottom of these grooves 62. Due to the flexibility of the legs stop 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.
- 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.
- parts 22-23 each include a stop plate 65-66.
- the extension tabs 28 and 32 on the sole 5 include on their external sides 28a and 32a protrusions 67-68.
- the stop plates 65-66 respectively come to bear on these protuberances 68-67, as illustrated by the Figures 4 and 5 .
- 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.
- 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. figure 7 .
- the suction head 1 also includes a stop piece 71 illustrated in figure 17 , which is fixed to the sole 5 and which includes a groove 72 in which comes place the rear brush 14, as illustrated in figure 19 .

- in the second position, mount the at least one brush and position it back from the underside while allowing the fork to pivot relative to the sole;
- in the third position, maintain the at least one brush set back from the underside by blocking the fork vis-à-vis the sole.
La première position est favorable à une utilisation sur des sols lisses tels qu'une surface carrelée, parquetée ou stratifiée. La seconde position est favorable à une utilisation sur de la moquette ou un tapis. La troisième position permet avantageusement de contraindre la semelle à s'incliner dans une position favorisant le grattage de la surface à aspirer. Ces différentes positions sont obtenues simplement en actionnant la manette, ce qui facilite grandement l'utilisation de la tête de succion.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.
