Description

DESCRIPTION

AUTOMATIC TELESCOPIC POLE AND CLEANING SYSTEM COMPRISING A

SUCH PERCH

Technical field of the invention

The present invention relates to a telescopic pole and a cleaning system comprising such a pole. It applies, in particular, to cleaning devices used in the field of window maintenance and cleaning.

State of the art

Window cleaning requires the intervention of a maintenance worker using a manual cleaning device. Some windows being placed at significant heights, the maintenance worker is required to use a ladder or a lift in order to access these different heights. However, such height access systems present a danger to the user.

Prior art solutions describe the use of telescopic poles in order to access adequate window heights to carry out cleaning. However, the length of the poles, modifiable thanks to the telescopic nature, can only be adjusted manually. Thus, adjusting the length of the pole requires several operations, causing a loss of time for the maintenance worker and a lack of maneuverability and practicality.

No solution of the prior art makes it possible to carry out easy maintenance of windows at significant heights and in a manageable and practical manner.

Summary of the invention

The present invention aims to remedy all or part of these drawbacks.

The present invention allows, by combining an automatic telescopic pole with a window cleaning device to form a cleaning system, easy access to window heights. In particular, the maintenance agent cleaning a window quickly, automatically and conveniently adapts the length of the telescopic pole.

Presentation of the invention

According to a first aspect, the present invention aims at a cleaning device which comprises, at least: a gripping handle for a user capable of being connected to a telescopic pole, a washing water tank, a waste water tank and a cleaning head, secured to the gripping handle, comprising: a drive motor, a friction roller comprising a shaft driven by the motor, a washing water injector connected to the washing water tank by a first pipe and a wastewater suction chute connected to the wastewater tank by a second pipe.

Thanks to these arrangements, the cleaning system comprising the cleaning device makes it possible to implement window cleaning which combines mechanical friction with a roller in the presence of washing water and suction of waste water. In particular, the cleaning device makes it possible to limit the effort made by the user, for example on the arm and wrist, to clean a window. In addition, the cleaning device makes it possible to limit the occasional or regular exposure of the user to water. washing and waste water. Such exposure corresponds for example to skin and/or ophthalmic projections. The risks of skin allergy, irritation or lesions are therefore reduced.

Furthermore, by implementing suction, the cleaning device makes it possible to limit discharges and the flow of wastewater. An additional step of cleaning the wastewater discharged and discharged, for example on the ground, is therefore avoided.

Thus, easy, quick and effective cleaning is achieved when using such a cleaning device.

In optional embodiments, the cleaning head of the cleaning device further comprises a blade called a “squeegee”, extending at least partially over a portion of the chute remote from the friction roller.

Thanks to these provisions, the squeegee allows you to achieve an adequate finish when cleaning the window. Thus, in a single pass and without excessive effort, the user cleans a portion of the window. The effectiveness of the cleaning device is thus improved.

In optional embodiments, a connection between the squeegee and a portion of the cleaning head is a pivot connection along an axis, this connection comprising a return means towards a predetermined angular position of rotation of the squeegee.

Thanks to these arrangements, the cleaning device allows an optimal finish of cleaning the window comprising, for example, a horizontal or vertical frame. In particular, at the junction between the window and the frame, the partially rotating free squeegee passes continuously from the window to the junction making it possible to remove most or even completely the used washing water from the surface of the window. window. In particular, at such a junction and when the squeegee returns to its initial position thanks to the return means, the waste washing water is directed towards the suction chute by the squeegee.

In optional embodiments, the cleaning head of the cleaning device further comprises at least one friction plate configured to come into contact with the window.

Thanks to these arrangements, friction on the window and therefore additional mechanical cleaning is achieved by the friction plate. The friction of the roller is therefore supplemented by the friction plate. Thus, more effective cleaning of the window is achieved.

In optional embodiments, the cleaning device further comprises: a pressure sensor configured to sense a pressure exerted on the friction roller during contact of the roller with the window, a detector of the crossing of a predetermined pressure in function of the pressure sensed and a means of activating and/or deactivating the drive motor depending on the crossing detected.

Thanks to these arrangements, the cleaning device allows activation of the rotation of the roller only when it comes into contact with the window. In particular, the risks of uncontrolled projection of water containing washing products by rotation of the roller are therefore limited. Furthermore, deactivating the rotation makes it possible to avoid continuous operation of the roller and therefore limits the energy consumption, for example in the form of electrical energy, of the cleaning device. Thus, the use of cleaning devices is easier and less energy-consuming. In optional embodiments, the drive motor of the scrubbing device is configured to rotate the scrub roller so as to direct the wastewater toward the suction chute.

Thanks to these arrangements, the cleaning device allows a rotation with a specific orientation towards the suction chute and therefore direct suction of waste water. More efficient wastewater suction is therefore achieved. Thus, uncontrolled wastewater discharges are effectively limited.

In optional embodiments, the friction roller has washing water passage holes.

Thanks to these arrangements, the circulation of washing water is facilitated. Thus, the distribution of the injected washing water is achieved in a more homogeneous and optimal manner.

In optional embodiments, an outlet of the washing water injector is arranged in an internal volume of the friction roller delimited by the washing water passage orifices.

Thanks to these arrangements, all of the washing water is brought into contact with the friction roller by circulating in particular through the passage orifices. The combination of the roller and contact with all the washing water therefore allows more effective friction of the roller and thus optimal cleaning.

In optional embodiments, the gripping handle further comprises a washing water injection handle, the cleaning device comprising means for activating and/or deactivating washing water injection operated by the injection lever.

Thanks to these arrangements, the cleaning device allows the user to control, in real time and dynamically, the injected washing water. Water consumption is therefore limited directly by the user. This results in significant water savings.

In optional embodiments, the cleaning head further comprises a connector with the gripping handle comprising a movable connection.

Thanks to these arrangements, the mobility of the cleaning head is greater. Such mobility being ensured, for example, by a pivot connection or a ball joint connection. Thus, the orientation of the cleaning head is easily achieved, for example, according to the needs of the user.

In optional embodiments, the cleaning system further comprises a backpack comprising: the washing water tank, the waste water tank, a washing water circulation means connected to the first pipe and configured to circulate the washing water and a waste water suction means connected to the second pipe and configured to exert a vacuum, the washing water and waste water tanks being connected with the device cleaning using the pole.

Thanks to these arrangements, the largest and heaviest elements of the cleaning system are supported by the user's back. In particular, when large volumes of water are consumed during cleaning, the use of the backpack makes it possible to distribute and support the masses of the different elements of the cleaning system. Furthermore, the backpack allows the user to move around more easily while supporting different loads. The mobility of the cleaning system is therefore increased, notably allowing greater freedom of movement for the user. By example, such a cleaning system allows compatibility with professional rope work.

According to a second aspect, the present invention relates to an automatic telescopic pole for supporting a window cleaning device, comprising: a lower gripping arm for a user; a first arm movable in sliding relative to the lower arm and connected to the cleaning device by a connection element; and a means for sliding the first movable arm relative to the lower arm, comprising: at least one wheel driven in rotation, the rotation of the wheel causing the sliding of the first movable arm, a motor for driving said wheel in rotation and means for activating and/or deactivating the drive motor.

Thanks to these arrangements, the pole allows easy access to a plurality of window heights without effort on the part of the user such as a maintenance worker. In particular, the telescopically and automatically deployable pole avoids the user having to manually modify the length of the pole. This allows the user to access variable window heights more precisely and saving time. In particular, the telescopic pole allows the user to reach heights and angles on the window to be cleaned that are initially difficult to access.

In optional embodiments, the pole also includes a handle called a “pressure handle” fixed in the upper half of the gripping arm.

Thanks to these arrangements, the pole allows the user to exert, using a lever arm, additional pressure on the cleaning device and therefore on the window to be cleaned. This makes cleaning the window more efficient.

In optional embodiments, the pole further comprises: an at least partial strapping secured to the lower gripping arm and a branch fixed to the strapping, supporting a wheel driven in rotation and maintaining the wheel resting on the first movable arm.

Thanks to these arrangements, the branch and wheel assembly participates in guiding and maintaining the first sliding movable arm. Thus, the stability of the first movable arm, during sliding, is improved.

In optional embodiments, at least one element among the lower gripping arm and the first movable arm has at least one longitudinal section for the passage of electrical supply wires.

Thanks to these arrangements, the power supply wires of the pole are included in an internal volume. For example, when the cleaning device coupled to the pole is electrically powered, these arrangements make it possible to prevent such wires from being free near the device. Thus, user safety is increased while ensuring maximum compactness of the pole.

In optional embodiments, the pole further comprises a winder of electrical power supply wires, arranged on a lower end of the lower gripping arm.

Thanks to these arrangements, the electrical wires are wound and unwound depending on the deployment or retraction of the pole and therefore according to the needs of the user. This reduces the risk of tangling or pinching electrical wires.

In optional embodiments, the connection element further comprises a second arm movable in sliding relative to the first movable arm, the pole comprising, in addition, a second means for sliding the second movable arm relative to the first movable arm. to the first movable arm, comprising: - at least one second wheel driven in rotation, the rotation of the second wheel causing the sliding of the second movable arm,

- a second motor for rotating said second wheel and

- a means of activating and/or deactivating the second drive motor.

Thanks to these arrangements, the pole allows greater access to a number of window heights. Furthermore, for the same pole deployment length, a pole with two movable arms is more stable than a pole with only one movable arm. In particular, the maintenance of the end of the second arm linked to the cleaning device is optimal.

In optional embodiments, the pole also includes an autonomous power supply.

Thanks to these provisions, the pole allows the user to avoid the need for a power supply near the pole. Thus, the boom is used in a large number of different environments without power supply constraints. Furthermore, these arrangements make it easier for a user to travel.

In optional embodiments, the pole further comprises at least two internal connection pipes connected to the cleaning device, one internal pipe being a washing water injection pipe and the other pipe being a washing water pipe. suction of waste washing water.

Thanks to these provisions, the compatibility of the pole with a cleaning device, combining injection and suction of waste water, is improved. Thus, the compactness and practicality of the pole are optimal.

In optional embodiments, the pole also includes a handle for injecting washing water into the injection pipe.

Thanks to these arrangements, the pole allows the user to control, in real time and dynamically, the washing water injected into the cleaning device. Water consumption is therefore limited directly by the user. This results in significant water savings.

According to a third aspect, the present invention aims at a cleaning system comprising a pole which is the subject of the invention and a cleaning device by injection of washing water and suction of used washing water.

The aims, advantages and particular characteristics of the system which is the subject of the present invention being similar to those of the pole which is the subject of the present invention, they are not recalled here.

Description of embodiments

The present description is given on a non-limiting basis, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

The expression "and/or", as used herein and in the claims, should be understood to mean "either or both" of the elements thus conjoined, i.e. that is, elements that are present conjunctively in some cases and disjunctively in other cases. Multiple elements listed with "and/or" must be interpreted in the same way, i.e. "one or more" of the elements thus conjoined. Other elements may possibly be present, other than the elements specifically identified by the "and/or" clause, whether or not they are related to these specifically identified elements. Thus, by way of non-limiting example, a reference to "A and/or B", when used in conjunction with open language such as "comprising" may refer, in one embodiment, to A only ( possibly including elements other than B); in another embodiment, to B only (possibly including elements other than A); in yet another embodiment, to A and B (possibly including other elements); etc.

As used herein in the description and in the claims, "or" should be understood to have the same meaning as "and/or" as defined above. For example, when separating elements in a list, "or" or "and/or" must be interpreted as inclusive, that is, the inclusion of at least one, but also more than one, a number or a list of elements, and, optionally, additional elements not listed. Only terms clearly indicating the contrary, such as "only one of" or "exactly one of", or, when used in the claims, "consisting of", refer to the inclusion of a single element of 'a number or list of elements. As used in the present description and in the claims, the expression "at least one", with reference to a list of one or more elements, must be understood as meaning at least one element chosen from one or more multiple items in the item list, but not necessarily including at least one of each item specifically listed in the item list and not excluding any combination of items in the item list. This definition also allows for the optional presence of elements other than the specifically identified elements in the list of elements to which the expression "at least one" refers, whether or not they are related to these specifically identified elements. Thus, by way of non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B", or, equivalently, "at least l 'one of A and/or B') may refer, in one embodiment, to at least one, optionally including more than one, A, without B present (and optionally including elements other than B); in another embodiment, at least one, optionally comprising more than one, B, without A present (and optionally comprising elements other than A); in yet another embodiment, at least one, optionally comprising more than one, A, and at least one, optionally comprising more than one, B (and optionally comprising other elements); etc.

In the claims, as well as in the description below, all transitional expressions such as "comprising", "including", "carrying", "having", "containing", "involving", "holding", "composed of ", and others, must be understood as open, that is, as meaning including, but not limited to. Only the transitional expressions "consisting of" and "consisting essentially of" are to be understood as closed or semi-closed transitional expressions, respectively.

We recall here the following definitions:

The term “telescopic” refers to an object comprising at least two elements capable of sliding relative to each other and in particular one into the other. In other words, one element forms a slide and the other forms a slide.

The term “automatic” refers to an element whose movement is achieved by mechanical means without human intervention. In particular, such mechanical means are supplied with electrical energy.

The term “window” designates a substantially smooth surface, for example made of glass. For example, such a surface is substantially vertical or inclined, preferably having an angle of inclination relative to the ground of between 45° and 90°.

The term “washing water” designates water containing maintenance products suitable for cleaning and known to those skilled in the art. Preferably such products are suitable for cleaning windows and have, for example, degreasing properties.

The term “mobile” designates an element having at least two degrees of freedom, for example in translation. For example, the translation movement allows sliding of an element relative to another element.

The term “activation and/or deactivation means” designates an electronic component or software, configured to emit a positive command corresponding to an activation or deactivation action or only a positive command for one of these actions, 'other action corresponding to an absence of a command issued. The term “roller” designates, for example, an element in the form of a truncated cylinder having a circular section, but can also correspond to an element having a section of any shape, for example, octagonal. Preferably such a section is generally circular. A friction roller is known in particular to those skilled in the art and comprises a coating capable of producing mechanical friction on a surface to be cleaned, such as a set of friction fibers.

The term “mobile” designates an element having at least two degrees of freedom, for example in rotation.

Throughout the description, we call “upper” everything that is at the top in Figures 1 to 11 which corresponds to the normal configuration of use of the device, and “lower” everything that is at the bottom in Figures 1 to 11. The terms “vertical” or “height” arise from these definitions. In Figure 1, a pole has a longitudinal axis called “axis A”, such an axis extending along a largest dimension of the pole and corresponding to the length of the pole. Axis A corresponds to a translation axis, a movement made during the sliding of certain elements of the pole.

Note now that the figures are not to scale.

We observe, in Figure 1, which is not to scale, a schematic view of an embodiment of the pole 100 which is the subject of the present invention. Note that the pole 100 and a cleaning device 105 form a window cleaning system 1000. For example, the pole has a cross section in the shape of a circle or hexagon. Preferably the pole is in the shape of a cylinder trunk.

We note, in Figure 1, that the automatic telescopic pole 100 is a support for a window cleaning device 105 (not shown). The automatic pole 100 includes:

- a lower gripping arm 110 for a user;

- a first arm 115 movable in sliding relative to the lower arm 110; And

- a sliding means 125 of the first arm 115 movable relative to the lower arm 110.

We observe, in Figure 1, that the sliding of the first arm 115 is represented by a pair of arrows:

- the solid line arrow represents the sliding movement carried out to deploy the first arm 115, such deployment corresponding to an increase in the length of the pole 105 and

- the dotted line arrow represents the sliding movement carried out to retract the first arm 115, such retraction corresponding to a reduction in the length of the pole 105.

In embodiments, such as that shown in Figure 1, the first arm 115 is connected to the cleaning device 105 by a connection element 120. The connection element 120 is, for example, a fitting (not shown) adapted to connect the first arm 115 to the cleaning device 105 or comprises another sliding arm 121 mentioned in the remainder of the description.

In embodiments, such as that shown in Figure 1, the sliding means 125 comprises: a wheel 130, a drive motor 135 and means of activation and/or deactivation 140 of the drive motor 135.

Note that the wheel 130 is rotated by the drive motor 135. Such rotation causes the sliding of the first movable arm 115. Preferably, the motor 135 is incorporated into the wheel 130. The rotation of the wheel 130 is around an axis (not shown), called the axis of rotation, preferably perpendicular to the axis A of the pole 100. We observe, in Figure 1, that the rotation of the wheel 130 is represented by two curved arrows:

- the curved black arrow represents the rotation allowing the deployment of the first arm 115 and corresponding in particular to an increase in the length of the pole 105, and

- the curved white arrow represents the rotation allowing the retraction of the first arm 115 and corresponding in particular to a reduction in the length of the pole 105.

In embodiments, such as that shown in Figure 1, the activation and/or deactivation means 140 is electrically connected to a switch 167. In other words, the switch 167 activates the raising or lowering of the first arm 115.

In embodiments, such as that shown in Figure 1, the pole 100 comprises a strapping 112 and a rigid branch 113 fixed to the strapping 112.

We observe, in Figure 1, that the strapping 112 is secured to an upper end of the lower gripping arm 110. The strapping 112 is fixed to the rigid branch 113 for example by welding.

Note that the rigid branch 113 supports the wheel 130 driven in rotation. Such a rigid branch 113 keeps the wheel 130 resting on the first movable arm 115. In particular, the rigid branch 1 13 and wheel 130 assembly participates in guiding the sliding movement of the first arm 115.

In embodiments, such as that shown in Figure 1, an electric wire 141 for powering the motor 135 incorporated in the wheel 130 extends along the internal volume delimited by the rigid branch 113. In these embodiments, the rigid branch 113 has a longitudinal hollow volume. In variants, such an electric wire is external to the rigid branch 113.

In embodiments, such as that shown in Figure 1, the sliding means 125 of the first movable arm 115 further comprises an additional wheel 132 driven in rotation.

In these embodiments, the wheel 132 is rotated by an additional drive motor 137. Note that the rotation of the additional wheel 132 contributes to the sliding of the first movable arm 115 disposed between the two wheels, 130 and 132. In variants (not shown), the additional wheel 132 is rotated by the sliding of the first arm 115 and is thus adapted for guiding the first arm 115 during sliding.

Preferably, when the wheel 132 is rotated by the additional drive motor 137, the activation and/or deactivation means 140 of the drive motor 135 is common to the additional drive motor 137. In variants, the additional drive motor 137 is electrically connected to activation and/or deactivation means separate from the activation and/or deactivation means 140.

In embodiments, such as those shown in Figure 1, the pole 100 comprises an additional rigid branch 114 fixed to the strapping 112. Note that the additional rigid branch 114 supports the additional wheel 132 driven in rotation and maintains the additional wheel 132 resting on the first movable arm 115. In particular, the force exerted on one wheel, 130 or 132, is opposed to the force exerted on the other wheel, 130 or 132. Thus, during sliding, the support and guidance of the first arm 115 are improved. The first arm 115 held between the two wheels, 130 and 132, respectively supported by the rigid branches, 113 and 114, therefore presents optimal stability and resistance to mechanical stress.

In embodiments, such as that shown in Figure 1, at least one element among the lower gripping arm 110 and the first movable arm 115 has at least one longitudinal section 116 for passing electrical power wires 118. Note that the power wires are, for example, power wires connected to the cleaning device 105. In embodiments not shown, when the pole is electrically connected to a mains socket, the power wires passing in the longitudinal section 116 are the power wires of the drive motor 135.

In embodiments, such as that shown in Figure 1, the lower gripping arm 110 comprises at least one longitudinal element 151 of complementary shape to the hollow volume delimited by the longitudinal section 116. In particular, such a longitudinal element is in contact with a portion opposite the portion of the longitudinal section 116 along which the electrical wires extend. Note that, during sliding, the longitudinal element 151 slides along the longitudinal section 116. Thus, the longitudinal section 116 participates in guiding the sliding of the first movable arm 115.

In embodiments, such as that shown in Figure 1, the first movable arm 115 comprises another hollow longitudinal section 152 extending at least partially over the length of the first arm 115. In particular, the lower gripping arm 110 comprises, in addition, another longitudinal element 153 of complementary shape to the hollow volume delimited by the other longitudinal section 152. Note that, during sliding, the other longitudinal element 153 slides along the other longitudinal section 152. Thus, the longitudinal section 152 participates in guiding the sliding of the first movable arm 115. Preferably, when the first movable arm 115 is a cylinder trunk, the two longitudinal elements, 151 and 153, are diametrically opposed. Thus the guiding of the sliding of the first arm 115 is optimized.

In embodiments, such as that shown in Figure 1, the connection element 120 further comprises a second arm 121 movable in sliding relative to the first movable arm 115.

In these embodiments, we note that the pole 100 further comprises a second means 126 for sliding the second movable arm 121 relative to the first movable arm 115. Note that the second sliding means 126 comprises: at least one second wheel 131, a second drive motor 136 and means of activation and/or deactivation 241 of the second drive motor 136.

Note that the wheel 131 is rotated by the drive motor 136. Such rotation causes the second movable arm 121 to slide. Preferably, the motor 136 is incorporated into the wheel 131.

The rotation of the wheel 131 is around an axis (not shown), called the axis of rotation, preferably perpendicular to the axis A of the pole 100.

In embodiments, such as that shown in Figure 1, the activation and/or deactivation means 241 is electrically connected to the switch 167. In other words, the switch 167 activates the raising or lowering of the second arm 121 . Preferably, the switch 167 also activates the raising or lowering of the first arm 115. In embodiments, the switch 167 activates: firstly, the raising of the first arm 115 then, secondly, the raising of the second arm 121, according to the needs of the user.

In variants (not shown), the switch for activating and/or deactivating the raising or lowering of the first arm 115 and the switch for activating and/or deactivating the raising or lowering of the second arm 121 are distinct.

In embodiments, such as that shown in Figure 1, the pole 100 comprises: a second strapping 162 and a rigid branch 163 fixed to the second strapping 162.

We observe, in Figure 1, that the second strapping 162 is secured to an upper end of the first movable arm 115. The second strapping 162 is fixed to the rigid branch 163, for example, by welding.

Note that the rigid branch 163 supports the second wheel 131 driven in rotation. Such a rigid branch 163 keeps the wheel 131 resting on the second movable arm 121. In particular, the rigid branch 163 and second wheel 131 assembly participates in guiding the sliding movement of the second arm 121.

In embodiments, such as that shown in Figure 1, the second sliding means 126 of the second movable arm 121 further comprises a second additional wheel 166 driven in rotation.

In these embodiments, the second additional wheel 166 is rotated by a second additional drive motor 168. Note that the rotation of the second additional wheel 166 contributes to the sliding of the second movable arm 121 disposed between the two wheels, 131 and 166. In variants (not shown), the second additional wheel 166 is rotated by the sliding of the second arm 121 and is thus adapted for guiding the second arm 121 during sliding.

Preferably, when the second additional wheel 166 is rotated by the second additional drive motor 168, the activation and/or deactivation means 241 of the second drive motor 136 is common to the second additional drive motor 168 In variants, the second additional drive motor 168 is electrically connected to activation and/or deactivation means separate from the activation and/or deactivation means 241.

In embodiments, such as those shown in Figure 1, the pole 100 comprises a second additional rigid branch 164 fixed to the second strapping 162. Note that the second additional rigid branch 164 supports the second additional wheel 166 driven in rotation and maintains the second additional wheel 166 resting on the second movable arm 121. In particular, the force exerted on one wheel, 131 or 166, is opposed to the force exerted on the other wheel, 131 or 166.

Thus, during sliding, the support and guidance of the second arm 121 are improved. The second arm 121 held between the two wheels, 131 or 166, respectively supported by the rigid branches, 163 and 164, therefore presents optimal stability and resistance to mechanical stress. In embodiments, such as that shown in Figure 1, the pole 100 includes an independent power supply 119. Such a power supply is electrically connected, for example, by electric wires, to the elements of the pole 100, such as:

- the means of activation and/or deactivation, 140 and 241,

- the drive motors, 135, 137, 136 and 138 and

- winders 117 and 123 mentioned in the remainder of the description.

For example, such an autonomous power supply 1 19 is a battery.

In embodiments, such as that shown in Figure 1, the pole further comprises an automatic winder 117 of electrical wires 118 for supplying the cleaning device 105. Note that the winder 117 is arranged on a lower end of the lower gripping arm 110.

In embodiments, such as that shown in Figure 1, the battery 119 is electrically connected, by electric wires 127, to the winder 117 of electric wires 118 supplying the cleaning device 105.

In embodiments, the battery 119 is also electrically connected to the automatic winder 123 of electrical wires 124 supplying the second rotation means 126. Preferably, the winders, 117 and 123, are independent. More preferably, the winder 123 has a smaller size than the winder 117. Such a difference in size is justified since the length of the electric wires 124 to be wound is less than the length of the electric wires 118 to be wound.

In embodiments, such as that shown in Figure 1, the electrical wires 118 supplying the cleaning device 105 extend along longitudinal sections 1 16, preferably aligned or slightly offset along the axis A, and included respectively in the lower gripping arm 110 and the first arm 1 15. We note, in Figure 1, that such electric wires

118 also extend along a longitudinal section included in the second arm 121.

In embodiments, such as that shown in Figure 1, the electrical wires 124 supplying the second rotation means 126 extend along longitudinal sections 116, preferably aligned or slightly offset along the axis A, and included respectively in the lower gripping arm 110 and the first arm 115.

In embodiments, such as that shown in Figure 1, the wires 127 connecting the battery 119 to the reel 117 are guided, at the level of the lower part of the lower gripping arm 110, by a guide wheel 128. Preferably, such a guide wheel 128 is fixed at the lower part of the lower gripping arm 110 via a rod 129. More preferably, the rod 129 is removable.

In embodiments, such as that shown in Figure 1, the wires 127 of the battery 119 are also connected to, and therefore supply electricity to, the winder 123 of electrical wires 124 supplying the second rotation means 126. Preferably, the wires 127 of the battery

119 are guided by the guide wheel 128.

In embodiments, such as that shown in Figure 1, a switch 133 for activating and/or deactivating the cleaning device 105 is included in the pole 100. Preferably, such a switch 133 is connected to the battery 119 and allows activating or deactivating the electrical power supply to the cleaning device 105 provided by the electrical wires 118. The embodiments and variants set out for the elements of Figure 1 are similar to those of the elements of Figure 2 having the same numbering.

In embodiments, such as that shown in Figure 1, the pole 100 also includes a handle 11 1 called a “pressure handle”. Note that such a handle is fixed in the upper half of the gripping arm 110.

We observe, in Figure 1, that the pressure handle 1 11 comprises an arm 169 and a sub-handle 161. Preferably a section of the handle 161 is a semi-circle. Note that arm 169 is a pressure arm. In particular, the lever arm effect is obtained when the user holding the gripping arm 110 with one hand pushes, with the other hand and in a movement directed towards the pole, the handle 161.

In embodiments, such as that shown in Figure 1, the pressure arm 169 comprises a housing suitable for inserting a removable battery 119 for electrical energy.

In embodiments, the pressure handle 111 is foldable. Preferably, the pole comprises a hollow housing of complementary shape to the pressure handle. For example, the folding of the pressure handle 111 is achieved by pivoting. In other words, the pressure handle 111 is fixed to the gripping arm 110 by a pivot connection. For example, a button present on the handle, known to those skilled in the art, is capable, for example of a pressed or non-pressed configuration, of authorizing or blocking the pivoting responsible for the folding of the pressure handle 111.

In embodiments, such as that shown in Figure 1, the pressure handle 111, and in particular the pressure arm 169, is fixed to the strapping 112.

In embodiments (not shown), the pole further comprises a strap for attaching a part of a user's body. In particular, such an attachment strap is fixed to the gripping arm 110. Preferably, the part of the user's body to which the strap is attached is the waist or hip circumference. Thus, the total weight of the pole surmounted by a cleaning device is distributed not only on the hand of the user holding the gripping arm 110 but also on the part of the body to which the strap is attached. The user's hand holding the gripping arm 110 is therefore relieved of part of the weight of the pole and cleaning device assembly.

The following embodiments and associated characteristics are stated in a non-limiting manner and correspond to preferred embodiments. In particular, the pole 100 shown in Figure 1 is preferably composed of three sliding arms. The first arm 110 is called a holding arm and allows the sliding of the two other arms, 115 and 121. The holding arm 110 is provided along its length with another arm called a pressure arm 169, this one making it possible to exert pressure on the entire pole 100 deployed by the user. The end of this arm 169 is provided with a semi-round handle 161. The interior volume of the pressure arm 169 is provided for inserting a removable battery 119 for electrical energy. Preferably, the pressure arm 169 is foldable along the holding arm 110, for example, by a pivot connection linking one end of this pressure arm 169 and the holding arm 110. The three arms, 110, 115 and 121, are provided inside their volume with two curved parts, 116 and 152, allowing the passage of electrical energy wires and serve as a guide for the sliding of the arms, 110, 1 15 and 121.

On the sliding side of the arms, 115 and 121, there is a circle, 112 and 162, provided with so-called compression arms, 113 and 114 or 163 and 164 , in order to press on the casters 130 and 132 or 131 and 166. The arms compression, 113 and 114 or 163 and 164, are curved making it possible to wrap a third of the sliding arms, 115 and 121. The battery 119 making it possible to supply electrical energy is connected directly to the circle 112 then by an electric wire in the compression arms, 113 and 114 and to the rotation casters, 130 and 132. The rotation casters, 130 and 132, are provided with motors, 135 and 137, inside, such motors allowing the rotation of the casters, 130 and 132. At the end of the holding arm 110 is provided a caster 128 fixed by a removable rod 129 as well as two automatic reels, 123 and

117, each independent and also removable. The winder 123 is smaller than the other winder 117. An electric wire 127 for energy is provided leaving from the battery 119 towards the wheel 128 and supplies the two winders, 117 and 123. A wire for energy 124 starting from the winder 123 is fixed on the strapping 162 and powers the rotation wheels, 131 and 166. Another electric wire starting from the winder 1 17 towards the bottom end of the arm 121 is provided to power a cleaning device 105. These two wires, 118 and 124, unwind and wind from the winders, 117 and 123, following the length determined by the user. These two wires, 118 and 124, are inserted into the curved part 116 of the arms, 110, 115 and 121. The handle 161 at the end of the pressure arm 169 is provided with a switch 167 for raising and lowering the sliding arms, 115 and 121. Another switch 133 is present for the power wire

118, for continuous use of the exterior cleaning device 105. A strap (not shown) is provided to relieve the weight of the system 1000 deployed by the user on the arm 110. Thus, an automatic pole made by electrical manipulation is provided for a desired height without effort.

We observe, in Figure 2, which is not to scale, a schematic view of an embodiment of the pole 200 which is the subject of the present invention. Note that the pole 200 and a cleaning device 105 form a window cleaning system 2000.

Note that an internal pipe 201 is an injection pipe 201 of washing water and the other pipe 202 is a pipe 202 of suction 202 of used washing water. Preferably the washing water injection pipe 201 is included in the volume delimited by the waste washing water suction pipe 202. The two pipes, 201 and 202, extend along the longitudinal axis (not shown) of the pole 200.

We observe, in Figure 2, that the washing water injection pipe 201 comprises three pipe portions each internal to a lower gripping arm 210, to a first movable arm 215 and to a second movable arm 221 of a connection element 220. Similarly, the waste washing water suction pipe 202 comprises three pipe portions each internal to a lower gripping arm 210, to a first movable arm 215 and to a second movable arm 221 of a connection element 220. For a pipe, 201 and/or 202, we note that the portions are connected in pairs to each other by waterproof connections, 204 and 207.

In embodiments, such as that shown in Figure 2, the washing water injection pipe 201 is connected, in the upper part, to the cleaning device 205 via a flexible pipe 203. In particular, the injection pipe 201 is made of rigid material.

In embodiments, such as that shown in Figure 2, the washing water injection pipe 201 is connected, on a lower portion, to a washing water supply pipe 211 connected, for example, to a water tank.

In embodiments, such as that shown in Figure 2, the pole 200 further comprises a lever 206 for injecting washing water into the injection pipe 201. Preferably, such a lever 206 regulates the injection of washing water via line 21 1.

In embodiments, such as that shown in Figure 2, the lever 206 is present in the lower part of the lower gripping arm 210.

In embodiments, such as that shown in Figure 2, the waste washing water suction pipe 202 is connected, in the upper part, to the cleaning device 205 via a connection pipe.

In embodiments, such as that shown in Figure 2, the waste washing water suction pipe 202 is connected, in the lower part, to a flexible suction pipe 209. For example, the flexible pipe d The suction 209 is connected to a waste water tank.

In embodiments (not shown), the pole comprises a telescopic hollow pipe for passing the two internal telescopic water injection and suction pipes. In particular, the two internal pipes are separate. The hollow pipe extends along the longitudinal axis (not shown) of the pole 200.

Note, in Figure 2, that the electrical supply wires are not shown.

The following embodiments and associated characteristics are stated in a non-limiting manner and correspond to preferred embodiments. The 200 pole allows cleaning at height and is adjustable to a defined height. The pole 200 includes, in its interior volume 202, a water injection 201 as well as the water suction 202. The pole is composed of several lengths made by pole arms, 210, 215 and 221. In particular, a fixed holding arm 210 as well as two telescopic arms, 215 and 221. The fixed arm is held by the user while the two other arms, 215 and 221 are designed to reach the planned length in height. The interior of the arms, 210, 215 and 221, are hollow 202. The holding arm 210, held by the user, is provided inside for the sliding of the two other arms, 215 and 221. An element of sealing connects two pipe sections, 201 and 202, sliding with each other. Inside the holding arm 210 as well as the two sliding arms, 215 and 221, a sliding water injection tube 201 is provided, hollow and rigid. The upper end of the tube 201 and the lower end of the tube 201 are respectively fixed to the upper end of the arm 221 and the lower end of the holding arm 210 for sliding. The lower end of the tube 201 present in the holding arm is blocked. Watertight connections, 204 and 207, are provided for the sliding of the pipes, 201 and 202. The connection 208 is provided on the sliding arm 221 at the end with a cleaning device 205 comprising an injection and a suction of water. The holding arm 210 is provided with a pressure arm 1 11 for its holding and strong pressure on the entire deployed pole 200. This pressure arm 1 11 is removable with locking by the user. The holding arm 210 is provided with a lever 206 for regulating the water to be injected outside it. This lever 206 is connected to the injection pipe 201 inside the holding arm. The injection pipe 201 is connected to a flexible pipe to connect to a device intended for injecting water 205 outdoors. The arms, 210, 215 and 221, of the pole 200 are hollow and are suitable for suction 202 of used water. The lower end of the holding arm 210 is connected to a flexible low suction pipe 209. All the connection elements are of the pole 200 are sealed at the sliding level, in particular the injection pipes 201, suction pipes 202 and the arms, 210, 215 and 221. Thus the pole 200 is able to be connected to two devices allowing the injection and suction of water. A connection 208 on the pole 200 comprising an orifice allowing the passage of the pipe for the injection of water towards the cleaning device 201.

We observe, in Figure 2, a cleaning system 2000 comprising a pole 200 and a device 205 for cleaning by injecting washing water and suction of used washing water.

Preferably comprises the cleaning system 2000 comprises a cleaning device, 1100, 1200, 1300, 1500 or 1600 as mentioned in the remainder of the description. In other words, the cleaning device 205 is preferably one of the cleaning devices chosen from the cleaning devices 1100, 1200, 1300, 1500 or 1600.

Note that, in Figures 3, 6, 9 and 10, the circulation of washing water is represented by a solid arrow and the circulation of waste water is represented by a dotted arrow.

We observe, in Figure 3, which is not to scale, a schematic view of an embodiment of the cleaning device 1100 capable of being coupled with a pole which is the subject of the present invention. The device 1100 for cleaning a window 101 comprises at least: a gripping handle 1105 for a user capable of being connected to a pole, a washing water tank 1110, a waste water tank 1115 and a head 1120 of cleaning.

We observe, in Figure 3, that the cleaning head 1120 is integral with the gripping handle 1105 and comprises: a drive motor 1125, a friction roller 1130, a washing water injector 1140 and a chute 1150 wastewater suction.

We note, in Figure 3, that the friction roller 1130 comprises a shaft 1135 driven by the motor 1125. Furthermore, in Figure 3, the cleaning head 1120 of the device 1100 comprises:

- a first pipe 1145 connecting the washing water injector 1140 and the washing water tank 1110, and

- a second pipe 1155 connecting the wastewater suction chute 1150 and the wastewater tank 1115.

Note that, in Figures 4, 5, 7 and 8, the washing water tank 1110 and the waste water tank 1115 are not shown.

In embodiments, such as that shown in Figures 3 and 6, the handle 1 105 includes an ergonomic portion, that is to say adapted to manual gripping by a user. In particular, such an ergonomic portion has a curved part.

In embodiments, such as those shown in Figures 3 to 8, the gripping handle 1105 is secured to the cleaning head 1120, in a non-removable manner.

Preferably, as visible in Figures 3 and 6, the part formed by the cleaning head, 1120 and 1320, and a portion of the gripping handle, 1105 and 1305, has a longitudinal profile in the shape of a swan's neck. We observe, in Figures 3 to 8, that the gripping handle, 1105 and 1305, is hollow longitudinally in order to enclose at least partially or even completely, in other words to wrap:

- part of the electrical connections necessary for the operation of the device, 1100, 1200, 1300 and 1500,

- part of the first pipe 1145 connecting the washing water injector 1140 and the washing water tank 1110.

Furthermore, part of the wastewater suction chute 1150 is preferably included in the gripping handle, 1 105 and 1305.

In embodiments, such as those shown in Figures 3 to 8, the gripping handle, 1105 and 1305, comprises a lever 1106 for injecting washing water.

In embodiments (not shown), the injection lever has the same function as a liquid sprayer commonly used in the packaging of household products, for example. In particular, such a sprayer injects the washing water punctually according to the pressure or release movement exerted by the user on the injection lever.

In other embodiments, the lever 1106 comprises a means 1107 for activating and/or deactivating the injection of washing water. Such an activation and/or deactivation means 1107 is actuated by the injection lever 1106. For example, the injection activation and/or deactivation means 1107 is a microcontroller. An activation means is configured to activate the injection of washing water as a function of the signal received by the injection lever 1106. On the contrary, a deactivation means is configured to deactivate the injection of washing water as a function of the signal received by the injection lever 1106. An injection activation and deactivation means 1107 is configured to perform these two functions.

We observe, in Figure 8, which is not to scale, a schematic view of an embodiment of the cleaning device 1500. The device 1500 comprises a cleaning head 1520 comprising a connector 1502. Such a connector 1502 secures the cleaning head 1520 with the gripping handle 1105. Note that the connector includes a mobile connection 1503.

In embodiments, such as that shown in Figure 8, the movable connection 1503 of the connector 1502 is a pivot connection of axis C parallel to the axis Z of rotation of the friction roller 1130. Such a connector is, for example, known in the field of vacuum cleaners allowing in particular rotation of a suction head of a vacuum cleaner.

In other embodiments (not shown), the movable connection 1503 of the connector 1502 is a pivot connection with an axis perpendicular to the axis Z of rotation of the friction roller 1130. In variants (not shown), the movable connection 1503 of the connector 1502 is a ball joint connection.

In embodiments, such as those shown in Figures 4, 5, 7 and 8, the cleaning head 1120 has a flared shape. Note that the flare is oriented opposite the junction with the grip, 1 105 and 1305.

In embodiments, such as those shown in Figures 3 to 8, the cleaning head, 1120, 1220, 1320 and 1520, includes a blade 1102 called a “squeegee”.

In these embodiments, the squeegee 1102 extends at least partially over a portion of the chute 1150 remote from the friction roller 1130. In particular, the scraper 1102 extends over the entire portion of the chute 1150 remote from the friction roller 1130. In embodiments, such as those shown in Figures 3 to 8, the squeegee 1102 is removable. In particular, the insertion or detachment of the squeegee 1 102 on the cleaning head, 1120, 1220, 1320 and 1520, is carried out by sliding the squeegee along an axis B. Preferably, the cleaning head, 1 120, 1220, 1320 and 1520, comprises a housing along the axis B of complementary shape to a longitudinal portion of the squeegee 1102.

Preferably, the squeegee 1102 is made of flexible material and in particular elastically deformable. For example, such a flexible material is rubber or any polymer or flexible material known to those skilled in the art.

In embodiments, such as that shown in Figure 11, a cleaning device 1700 comprises a blade called a “finishing” squeegee 1702. Note that the squeegee 1702 includes a bar 1704 supporting a rubber 1703. Preferably, the rubber 1703 is removable.

In embodiments, such as that shown in Figure 11, a connection between the squeegee 1702 and a portion of the cleaning head is a pivot connection along an axis B. Note that such a connection comprises a return means 1705 towards a predetermined angular position of rotation of the scraper 1702.

In other words, in Figure 11, the bar 1704 of the squeegee 1702 is fixed along the axis B and has freedom in rotation along the axis B represented by a double arrow. The rotation of the bar 1704 at a predetermined angle is reversible by the action of the return means 1705. For example, the angular position associated with this freedom in rotation is between 1 degree and 45 degrees, more preferably between 1 degree and 20 degrees. In particular, the angle of support, and therefore the angular position, of the bar 1704 on the window 101 varies according to the mechanical constraints exerted during the use of the device 1700 then returns to the initial angular position. Note that the initial angular position, corresponds to a predetermined angular position, is defined for example for an angle of rotation substantially equal to 0 degrees. This reversibility of rotation is obtained by the return means 1705. For example, such a return means 1705 is a spring. Note that the angle of freedom in rotation, or angular position, is conditioned by the return means 1705 and in particular according to its elastic properties.

In these embodiments, the angle of rotation along axis B of the strip 1704 varies depending on the positioning of the cleaning device 1700 and the force applied to the window 101 by the user. Thus, when the window 101 has a horizontal lower frame 1701 or vertical (not shown), and for example perpendicular to the window 101, the pivoting nature of the bar 1704 makes it possible to maintain the support of the rubber 1703 against the window 101 and at level of the junction between the window 101 and the frame 1701. An optimal cleaning finish is therefore obtained.

In embodiments, such as those shown in Figures 3 to 8, the cleaning head, 1120, 1220, 1320 and 1520, comprises at least one friction plate, 1103 and/or 1104. Note that such a friction plate, 1103 and/or 1104, is configured to come into contact with the window 101. In particular, at least a portion of the friction plate, 1103 and/or 1104, is aligned at a tangent of a directrix of the cylinder trunk formed by the friction roller, 1130 and 1330. Such a tangent includes at least one point of contact with the window 101 to be cleaned.

Preferably, a friction plate, 1103 and/or 1104, extends at least partially along a generator of the cylinder trunk formed by the friction roller, 1130 and 1330. Even more preferably, a plate, 1103 and/or 1104, extends over the entirety of a generatrix of the cylinder trunk formed by the friction roller, 1130 and 1330.

In embodiments, the contact surface of the friction plate, 1103 and/or 1104, with the window 101 has a surface comprising fibers, preferably natural fibers. Such fiber friction plates are known to those skilled in the art.

We observe, in Figure 5, which is not to scale, a schematic view of an embodiment of the cleaning device 1200. The device 1200 comprises a cleaning head 1220 comprising:

- a pressure sensor 1201 configured to sense a pressure exerted on the friction roller 1130 during contact of the roller 1130 with the window 101,

- a detector 1202 for crossing a predetermined pressure as a function of the pressure sensed and

- a means 1203 for activating and/or deactivating the drive motor 1125 depending on the crossing detected.

In embodiments, such as that shown in Figure 5, the sensor 1201 interacts with the activation and/or deactivation means 1203 via the detector 1202.

In embodiments, the means 1203 for activating or deactivating the drive motor 1125 is a microcontroller. An activation means 1203 is configured to activate the motor 1125 as a function of the signal received by the detector 1202. On the contrary, a deactivation means 1203 is configured to deactivate the motor 1125 as a function of the signal received by the detector 1202. means of activation and deactivation 108 of the motor 1 125 is configured to perform these two functions.

Note that, for example, a predetermined pressure corresponds to a minimum compression pressure of the friction roller 1130 on the window 101.

We observe, in Figures 3 and 6, that the cleaning head, 1120 and 1320, comprises a drive motor 1125. Such a motor 1125 causes a rotation of the shaft 1135 of the roller, 1130 and 1330, along the axis Z.

We observe, in Figures 4, 5 and 7 and 8, that the roller, 1130 and 1330, comprises a gear 136 secured to the shaft 1135 and configured to be rotated by a gear (not shown) of the motor. drive 1125. Note that the gear 136 of the roller, 1 130 and 1330, therefore ensures the rotation of the shaft 1135.

In embodiments, such as those shown in Figures 3 and 6, the drive motor 1125 is configured to rotate the friction roller 1130 so as to direct the wastewater towards the suction chute 1150.

Note that, in these embodiments, the rotation of the roller 1130 is conditioned by the rotation of the gear of the drive motor 1125. Thus, such a gear is adjusted so as to favor this preferential rotation.

In embodiments, motor 1125 is electrically powered. Such a power supply is produced, for example, by a battery (not shown) connected to the motor 1125. Note that the battery is connected to the motor 1125 by an electric cable 1126 shown in Figures 3 and 6.

We observe, in Figures 6 and 7, which are not to scale, two schematic views of an embodiment of the cleaning device 1300. The device 1300 comprises a friction roller 1330 having orifices 1301 for the passage of washing water. Preferably, as visible in Figure 7, the orifices 1301 for passing washing water are present along the friction roller 1330.

In embodiments, such as that shown in Figures 6 and 7, an outlet of a washing water injector 1340 is arranged in an internal volume of the friction roller 1330 delimited by the orifices 1301 for passing washing water. washing. In these embodiments, and when the roller has a friction thickness mentioned below, the washing water injected by the injector 1340 passes through the orifices 1301 and preferably firstly soaks the friction thickness then soaks the plates , 1103 and 1104, friction.

In embodiments, the friction roller, 1130 and 1330, comprises a friction thickness at least partially enclosing the external surface of the roller and configured to be brought into contact with the window 101.

Preferably, the friction thickness is flexible and in particular deformable under the action of mechanical stress, for example, when pressure is exerted by a user.

In embodiments, the friction thickness is a layer that includes fibers, for example natural fibers. Preferably, the fibers of the friction thickness have reduced hardness and abrasiveness in order to avoid scratching the window 101. Such fibers are known to those skilled in the art.

Thus, the thickness of fibrous friction limits the wear of the window 101 produced by the friction of the roller, 1130 and 1330, while ensuring the cleaning of the window 101.

Note that, when the flexible friction thickness is soaked in washing water, the pressure exerted by the user has the effect of crushing the friction thickness against the window 101. In this case, the point of contact between the friction thickness and the window 101 is generally aligned with the other points of contact between the friction plates, 1103 and 1104, and the window 101. Thus, in these embodiments, a overall contact and friction surface is formed during use of the device.

In embodiments, the wash water injector, 1140 and/or 1340, is an injection nozzle.

In embodiments, such as that shown in Figure 3, the injector 1140 diffuses washing water onto the external surface of the friction roller 1130.

In variants, such as that shown in Figure 6, the injector 1340 diffuses washing water inside the friction roller 1130, as mentioned previously.

In embodiments, such as those shown in Figures 3 to 8, the washing water injector is controlled by control means corresponding to the injection lever 1106, as mentioned previously.

Note that the first washing water circulation pipe 1145 can be in several nestable or clip-on parts, but also in a single continuous part.

In embodiments, such as those shown in Figures 3 and 6, the suction chute 1150 is connected to the wastewater tank 1115 by the second pipe 1155. The wastewater tank 1115 is, for example, connected to a suction means. Such a suction means is configured to put the wastewater tank 1115 under depression and carry out suction.

In embodiments, the chute includes at least one solids filter along the wastewater passage. Note that the second wastewater circulation pipe 1155 can be in several nestable or clip-on parts, but also in a single continuous part.

In embodiments, at least one tank among the washing water tank 1110 and the waste water tank 1115 is attached to the gripping handle 1105. Such embodiments are suitable, for example, for devices of reduced size, in particular not exceeding a certain mass and for cleaning which does not require a significant quantity of water.

In these embodiments, the reservoirs, 11 10 and/or 11 15, are, for example, refillable or removable and therefore replaceable.

We observe, in Figure 9, the device 1600 comprising a backpack 1602 which includes the washing water tank 1610 and the waste water tank 1615. Such a backpack 1602 is also called a “back element”.
