Description
Technical Field
The present invention relates to the field of vacuum cleaners equipped with a vacuum cleaner nozzle, also called suction nozzle, which allows to suck up dust and dirt on a surface to be cleaned, which may be e.g. a tile, parquet floor, laminate, carpet tile or carpet.
Background
Document FR3062562 discloses a vacuum cleaner nozzle comprising:
a floor provided with a lower surface and a suction chamber opening on the lower surface,
a fork hingedly mounted to the floor by a front pivot link defining a front pivot axis extending transversely to the displacement direction of the suction nozzle of the cleaner,
two main wheels designed to roll on the surface to be cleaned, rotatably mounted on the fork about an axle substantially parallel to the front pivot axis, and
-a connection sleeve fluidly connected to the suction chamber.
The connecting sleeve more particularly comprises a first sleeve part which is hingedly mounted on the fork by means of a rear pivot coupling defining a rear pivot axis extending parallel to the front pivot axis, and a second sleeve part to which the suction tube of the vacuum cleaner is designed to be fastened.
The first and second sleeve portions are mounted for rotational movement relative to each other about an axis of rotation perpendicular to the front and rear pivot axes. This configuration of the connection sleeve allows in particular to increase the manoeuvrability of the suction tube fastened to the connection sleeve and thus of the aforementioned suction nozzle of the vacuum cleaner.
However, when a user wants to suck up e.g. refuse under furniture or a bed with a vacuum cleaner equipped with such a nozzle, the rearward pivoting of the connecting sleeve, and thus of the suction tube, is limited by the quick contact of the first sleeve part with the surface to be cleaned. Therefore, the suction nozzle does not allow easy suction of the refuse located under the furniture or the bed due to the large height dimension of the suction nozzle.
Furthermore, such a rearward pivoting of the connecting sleeve may result in a lifting of the front portion of the lower surface of the soleplate due to the mass of the suction tube applied to the fork, which is detrimental to the suction quality of the suction nozzle.
Disclosure of Invention
The present invention aims to remedy these drawbacks.
The problem underlying the present invention is in particular to provide a structurally simple and economical suction nozzle for a vacuum cleaner, while allowing efficient and easy suction, in particular under furniture or beds.
To this end, the subject of the invention is a suction nozzle for a vacuum cleaner, comprising:
a floor provided with a lower surface and a suction chamber opening on the lower surface,
a fork hingedly mounted to the floor by a front pivot link defining a front pivot axis extending transversely to the displacement direction of the suction nozzle of the cleaner,
two main wheels designed to roll on the surface to be cleaned, rotatably mounted on the fork about an axle substantially parallel to the front pivot axis, and
the suction tube of the vacuum cleaner is designed as a connection sleeve fastened to, which is fluidly connected to the suction chamber.
The vacuum cleaner nozzle further comprises a coupling member mechanically connecting the connecting sleeve to the fork, said coupling member being hingedly mounted on the fork by a central pivot coupling defining a rotation axis extending transversely to the front pivot axis, and the axle being secant with the coupling member.
This arrangement of the coupling member and the provision of the central pivot coupling allow the height dimension of the suction nozzle to be reduced when the suction tube fastened to the connection sleeve is placed substantially horizontally near the surface to be cleaned, so that the suction nozzle can be easily displaced under furniture or a bed.
This arrangement of the centre pivot coupling, in combination with the mounting of the main wheel on the fork, also allows preventing the main wheel from lifting when the cleaner nozzle is turned due to the user applying torque on the suction duct and/or lateral tilting of the suction duct. Thus, these arrangements ensure an improvement in suction efficiency.
Furthermore, the fact that the axle is secant with the coupling member allows to increase the stability of the suction nozzle of the vacuum cleaner according to the invention.
The vacuum cleaner nozzle may also have one or more of the following features, either alone or in combination.
According to an embodiment of the invention, the central pivot coupling is located between the front pivot coupling and the axle. This arrangement of the central coupling allows to prevent lifting of the front part of the lower surface of the soleplate when the suction tube fastened to the connecting sleeve is pivoted backwards, so that an optimal suction efficiency is ensured even when sucking waste located under furniture or beds. Furthermore, this arrangement of the central coupling allows a better distribution of the vertical forces caused by the mass of the suction tube over the suction nozzle, in particular preventing this vertical force from being applied directly to the main wheel.
According to an embodiment of the invention, the rotation axis is substantially perpendicular to the front pivot axis.
According to an embodiment of the invention, the rotation axis is substantially horizontal or inclined with respect to the horizontal surface by an angle of inclination of less than 10 °, for example less than 5 °, when the two main wheels of the suction nozzle of the cleaner rest on the horizontal surface. These arrangements allow for a convenient displacement of the suction nozzle when the user applies a pushing force on the suction nozzle through the suction tube fastened to the connection sleeve without compromising the suction efficiency of the suction nozzle.
According to an embodiment of the invention, a plane passing through the front pivot axis and the axle is secant with the coupling member. These arrangements allow to further reduce the height dimension of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the connecting sleeve is hingedly mounted on the coupling member by a rear pivot coupling defining a rear pivot axis substantially parallel to the front pivot axis.
According to an embodiment of the invention, the central pivot link is located between the rear pivot link and the front pivot link. This arrangement of the pivot coupling allows avoiding making the connection sleeve in a rigid curved form (which is then present, for example, in a flexible coupling conduit fluidly connecting the connection sleeve to the suction chamber), and thus enables positioning the connection sleeve substantially horizontally for easy sucking away of the waste underneath the furniture.
According to an embodiment of the invention, a plane passing through the front pivot axis and the rear pivot axis is secant with the coupling member. These arrangements allow to further reduce the height dimension of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the distance between the rear pivot axis and the horizontal surface is substantially equal to or greater than the distance between the wheel axle and the horizontal surface when the two main wheels of the suction nozzle of the cleaner rest on the horizontal surface.
According to an embodiment of the invention, the rear pivot axis substantially corresponds to the axle.
According to an embodiment of the invention, the rear pivot axis is offset rearward relative to the wheel axis. This arrangement of the rear pivot axis further improves the stability of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the fork comprises two fork arms hingedly mounted to the base plate by a front pivot coupling, and a coupling portion interconnecting the two fork arms and extending transversely to the fork arms.
According to an embodiment of the invention, each yoke extends substantially parallel to the displacement direction of the suction nozzle of the cleaner.
According to an embodiment of the invention, the coupling portion extends below the coupling member. These arrangements further reduce the height dimension of the suction nozzle of the cleaner according to the invention on the one hand, and on the other hand allow the fork to support and distribute torsion forces due to the left/right rotational movement.
According to an embodiment of the invention, each yoke comprises a free end, the free ends of the two yoke respectively comprising two lugs which are substantially coaxial and project in a direction transverse to the yoke, the two lugs partly forming the front pivot coupling.
According to an embodiment of the invention, the central pivot coupling is arranged between the two fork arms. These arrangements allow to further reduce the height dimension of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the coupling member comprises a mounting portion which is ring-shaped and is rotatably movably mounted on the fork about the rotation axis.
According to an embodiment of the invention, the distance between the mounting portion and the rear pivot axis is smaller than the distance between the mounting portion and the front pivot axis. These arrangements allow the mass of the suction pipe to be distributed more over the main wheel than the sole plate, thereby preventing the sole plate from sinking too much on a soft, felt-type floor.
According to an embodiment of the invention, the coupling member further comprises a support portion on which the connecting sleeve is hingedly mounted.
According to an embodiment of the invention, the main wheels are arranged on both sides of the fork. This arrangement of the main wheel further reduces the height dimension of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the main wheels are arranged on both sides of the coupling member. This arrangement of the main wheel further improves the stability of the suction nozzle of the vacuum cleaner according to the invention and further reduces the height dimension of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the front pivot axis is substantially perpendicular to the displacement direction of the suction nozzle of the vacuum cleaner.
According to an embodiment of the invention, the rotation axis is located below a plane passing through the front pivot axis and the wheel axle. This arrangement of the rotation axis further improves the stability of the suction nozzle of the vacuum cleaner according to the invention.
According to an embodiment of the invention, the rotation axis is located in a median vertical longitudinal plane of the suction nozzle of the cleaner.
According to an embodiment of the invention, the suction cleaner nozzle comprises a flexible coupling conduit fluidly connecting the suction chamber to the connection sleeve.
According to an embodiment of the invention, the coupling member defines a channel in which the flexible coupling conduit extends. Advantageously, the mounting portion extends around the flexible coupling conduit.

Detailed Description
Only those elements necessary for an understanding of the present invention are shown in the drawings. To facilitate reading of the drawings, like elements are denoted by like reference numerals in the different drawings.
Figures 1 to 7 show a cleaner nozzle 2 comprising a sole plate 3, the sole plate 3 being provided with a lower surface 4 designed to be positioned close to a surface to be cleaned during use of the cleaner nozzle 2.
The soleplate 3 is further provided with a suction chamber 5 which is open on the lower surface 4. Advantageously, the suction chamber 5 is elongate and extends in an extension direction D1, which extension direction D1 is transverse to the displacement direction D2 of the suction nozzle 2 of the cleaner, for example perpendicular to the displacement direction D2.
The cleaner nozzle 2 further comprises a fork 6, which fork 6 comprises two fork arms 7 and a coupling part 8, which coupling part 8 connects the two fork arms 7 to each other and extends transversely to the fork arms 7. Each yoke 7 extends, for example, substantially parallel to the displacement direction D2 of the cleaner nozzle 2 and comprises a free end. However, the prongs 7 may be slightly inclined with respect to each other and diverge, for example in the direction of the base plate 3.
The two fork arms 7 are hingedly mounted on the floor 3 by a front pivot coupling P1, the front pivot coupling P1 defining a front pivot axis X1, the front pivot axis X1 extending perpendicular to the displacement direction D2 of the cleaner nozzle 2, the front pivot axis X1 being substantially horizontal when the cleaner nozzle is resting on a horizontal surface. In this way, the fork 6 can be tilted backwards or forwards with respect to the bottom plate 3, as indicated by arrows F1 and F2 in fig. 6, respectively.
According to the embodiment shown in the figures, the free ends of the two prongs 7 each comprise two lugs 9, which are substantially coaxial and project opposite each other in a direction transverse to the prongs 7. The two lugs 9 are accommodated in corresponding recesses provided on the base plate 3 and form, in part, the front pivot coupling P1.
The cleaner nozzle 2 further comprises two main wheels 11, also called rear wheels, which are designed to roll over the surface to be cleaned. Two main wheels 11 are rotatably movably mounted on the fork 6 about an axle a, which is parallel to the front pivot axis X1, so that the axle a is also substantially horizontal when the cleaner nozzle 2 is resting on a horizontal surface. Advantageously, the main wheels 11 are provided on both sides of the fork 6, more specifically on both sides of the coupling portion 8.
The cleaner nozzle 2 further comprises a connection sleeve 12, the end of which connection sleeve 12 is connected to a nozzle (not shown) of a suction tube, which nozzle is in turn connected to a suction system (not shown) of the cleaner. There are already on the market various variants of vacuum cleaners which can be used with the vacuum cleaner nozzle 2 according to the invention; these variants are known to the person skilled in the art and are not described in detail in this document.
The cleaner nozzle 2 further comprises a flexible coupling conduit 13 (see fig. 4) fluidly connecting the suction chamber 5 to the connection sleeve 12.
The cleaner nozzle 2 further comprises a coupling member 14 which mechanically connects the connecting sleeve 12 to the fork 6. Advantageously, the coupling portion 8 of the fork 6 extends below the coupling member 14 and the main wheel 11 is arranged on both sides of the coupling member 14.
The connecting sleeve 12 is more specifically hingedly mounted on the coupling member 14 by a rear pivot coupling P2, the rear pivot coupling P2 defining a rear pivot axis X2 parallel to the front pivot axis X1. In this way, the connecting sleeve 12 can be tilted back or forth relative to the coupling member 14, as indicated by arrows F3 and F4 in fig. 6.
According to the embodiment shown in the figures, the distance between the rear pivot axis X2 and the horizontal surface is greater than the distance between the wheel axis a and the horizontal surface when the two main wheels 11 of the cleaner nozzle 2 rest on the horizontal surface. According to the embodiment shown in the figures, the rear pivot axis X2 is slightly offset rearward with respect to the axle a. However, according to alternative embodiments of the invention, the rear pivot axis X2 may correspond to the axle A or be offset slightly forward relative to the axle A. This arrangement of the rear pivot axis X2 allows preventing tilting of the suction nozzle when the user applies pressure to the suction tube connected to the connection sleeve 12.
The coupling member 14 is mounted articulated on the fork 6 by a central pivot coupling P3, the central pivot coupling P3 defining a rotation axis X3 extending perpendicular to the front pivot axis X1. The center pivot link P3 is located between the rear pivot link P2 and the front pivot link P1, more specifically, between the front pivot link P1 and the axle a. Advantageously, the central pivot coupling P3 is arranged between the two prongs 7.
As shown more particularly in fig. 6, when the two main wheels 11 of the suction nozzle 2 rest on a horizontal surface, the rotation axis X3 is substantially horizontal or inclined with respect to the horizontal surface by an inclination angle of less than 10 °, for example less than 5 °.
As also shown in fig. 6, the axle a is secant with the coupling member 14, and a plane passing through the front pivot axis X1 and the axle a is also secant with the coupling member 14. Advantageously, the rotation axis X3 lies in a median vertical longitudinal plane of the suction nozzle 2 of the cleaner. The axis of rotation X3 may be located slightly above or below a plane passing through the front pivot axis X1 and the axle a.
According to the embodiment shown in the figures, the coupling member 14 comprises an annular mounting portion 14.1 which is mounted on the fork 6 in a rotationally movable manner about the rotational axis X3, and a support portion 14.2, the connecting sleeve 12 being mounted in a hinged manner on the support portion 14.2.
The coupling member 14 defines a channel 15 in which the flexible coupling conduit 13 extends. Advantageously, the mounting portion 14.1 extends around the flexible coupling duct 13 and the support portion 14.2 has a generally U-shaped cross section and extends below the flexible coupling duct 13.
The cleaner nozzle 2 further comprises a guide member 16, which guide member 16 extends transversely to the yoke 7 and above the mounting portion 14.1. The guide member 16 includes an arcuate guide portion and two end portions which are provided on both sides of the coupling member 14 and each of which is fastened to the fork 6. The fork 6 and the guide member 16 are configured to guide the coupling member 14 to rotate about the rotation axis X3 and thus form, in part, the central pivot coupling P3.
Of course, the invention is not limited to the embodiments described and shown, which are provided as examples only. Modifications may be made, especially in matters of construction of the various elements or substitution by equivalent techniques, without departing from the scope of the invention.
