Description

SPINNING DEVICE WITH DEFORMABLE HOUSING

The present invention relates to a device for wiping a cleaning system for a broom, such as a mop or other cleaning cloth for a broom. The invention also relates to a cleaning assembly comprising such a dewatering device.

It is known a wringing device comprising a wringing grid formed integrally - for example by plastic injection molding - with a body adapted to be supported on a bucket. Spinning of the cleaning system is then performed by pressing the cleaning system against the spin screen. The liquid initially contained in the cleaning system is then received directly into the bucket.

The grid may be curved to receive the cleaning system.

However, this type of spin device does not make it possible to obtain a very satisfactory spin of the cleaning system. Indeed, only the part of the cleaning system (in particular the mop) in contact with the grid can be effectively dewatered. However, most of the cleaning system is pressed against itself, thus not allowing the liquid to be evacuated, it is at best moved from one part of the cleaning system to another.

On the basis of this observation, the object of the present invention is to provide a wiper system of the cleaning system for a broom improving the situation.

To this end, the present invention provides a device for wiping a cleaning system for a broom, in particular for a flat broom, the wiper device comprising first and second interlocking grids forming the walls of a housing of dewatering the cleaning system inside the wiper device, the first and second gates being adapted to be moved relative to each other to deform the housing.

In preferred embodiments, the wiper comprises one or more of the following features:

- Means for holding the wiper device on a rim of a bucket for disposing the wiper device above the bucket;

the first and second grids are formed at one end of a first and a second plate, respectively, the wiper device comprising a body integral with the holding means, the first and second plates being adapted to be attach to the body, in particular by means of clips; an end portion of the second gate extends beyond the first gate;

the end portion of the second grid forms stop means for preventing the second grid from moving relative to the first grid so that the first and second grids no longer intersect;

the first and second plates delimit a flared opening opening from the cleaning system to the housing;

- A guide groove of a blade is formed on at least one of the first and second plates at the passage opening;

the first and second grids are arranged so as to form a U-shaped section, the first grid forming a first branch of the U-shaped section, the second grid forming the second branch and the base of the U-shaped section.

The invention also provides a cleaning assembly comprising a bucket having a rim and a wiper as described above adapted to be maintained above the bucket by pressing on the rim of the bucket.

In preferred embodiments, the cleaning assembly includes one or more of the following features:

- a flat broom;

- The blade includes a handle for gripping the blade, a mounting plate of a brush cleaning system, disposed at one end of the handle and a brush cleaning system adapted to be fixed on the mounting plate;

the attachment plate of the blade comprises at least two pins mounted free to rotate on the fixing plate, the cleaning system comprising fixing eyelets adapted to cooperate with the pins of the plate to allow the passage of the pins in the eyelets in a first relative position of the nipples relative to the eyelets, and to prevent the passage of the nipples in the eyelets in a second relative position of the nipples relative to the eyelets;

- The deck of the blade has a first and a second platinum parts hinged together to be folded against each other, in the extension of the gripping handle of the blade;

- The pins are adapted to be received in the or, where appropriate, the guide grooves of the first and second plates during the insertion of the blade in the passage opening;

- The plate has a projection adapted to be received in one of the guide grooves of the first and second plates during the insertion of the blade in the passage opening. Other features and advantages of the invention will appear on reading the following description of a preferred embodiment of the invention, given by way of example and with reference to the accompanying drawings.

The following description discusses an example of a wiper device for a broom cleaning system. By way of non-limiting example, the cleaning system considered here is a mop, it being understood that any other cleaning system for a broom may be implemented, especially any cleaning system for a broom comprising a cleaning cloth, such as a cleaning cover which covers a plate of a broom, or, more generally, a flexible sheet adapted to cleaning. An example of such a flexible sheet is a fringe sheet of the type used on the mops.

An example of a squeezing device 10 of a syringe is shown in FIGS. 1 and 2.

The wiper device 10 as illustrated consists of a body 12, and two plates 14, 16 fixed to the body 12.

The body 12 essentially comprises three parts:

two side wings 18, 20; and

a substantially cylindrical central portion 22 of rectangular section, on which are fixed the two plates 14, 16.

Each side wing 18, 20 forms a groove 24, 26 adapted to receive a rim of a bucket of water, to maintain the body 12 (and thus the wiper device 10) in position above the bucket. In this case, to ensure a better hold of the wiper device on a bucket - which generally has an angled rim - each side flange 18, 20 has one or preferably several tongues 28. The tongues 28 extend in the groove 24, 26 formed by the lateral flange 18, 20. These tongues extend substantially parallel to the bottom of the groove 24, 26 (that is to say in the position of use, the tongues are substantially horizontally). These tongues 28 make it possible to cooperate with the bent rim of the bucket - which is received between the bottom of the groove 24, 26 and the tongue 28 - to ensure greater stability of the wiper device 10 above it.

Furthermore, as indicated above, the central portion 22 ensures the fixing of the plates 14, 16. Here, the plates 14, 16 are clipped onto the central portion 22 by means of notches 30 notch, made on the plates 14, 16 , which are received in force in openings 32 made in the central cylindrical portion 22 of the body 12. In this case, four pairs of pin / aperture per plate 14, 16 are used, the pin / lug torques forming, for each plate 14 , 16, the vertices of a rectangle. This ensures a quick and efficient attachment of the plates 14, 16 on the body 12. In addition, the lugs, respectively the openings, can be made quickly and for a reduced cost during the injection molding of the plates, respectively of the body. In addition, it can be provided that the lugs are made on the body and corresponding openings on the plates. However, this embodiment appears less favorable. Indeed, in this case, the lugs may protrude into a passage opening 34 (described in more detail below) and then hinder the insertion of a mop mop in the wringing device 1 0.

The plates 14, 16 will now be described in more detail, in particular with reference to FIG. 2.

The first plate 14 is of substantially flat shape. At one of its ends 36 - intended to be the upper end - the first plate 14 is slightly curved. The plate 14 comprises a central groove 38. Finally, at its end 40, opposite to the upper end 36, the first plate 14 comprises a first grid 42. Grid means here and in the rest of the present description, a following bars parallel and not a grid of bars.

The second plate 1 6 has a structure substantially identical to that of the first plate 14 at its upper end 44 slightly convex. The second plate 16 also has a groove 46. However, at its lower end 48, the second plate 16 has a second grid 50 curved. The outer surface of each bar of the second grid 50 has a protrusion 53. The protuberance 53 is preferably made near the top of each bar, that is to say substantially at the point intended to be the lowest in use. . In addition, the end of the bars forming the second gate 50 has an extra thickness.

When the first 14 and second 16 plates are fixed on the body 12 of the dewatering device 10, the bars of the second grid 50 intersect with the bars of the first grid 42. The first 42 and second grid 50 then form a housing 51. The walls of this dwelling have a U-shaped section, the first gate 42 forming a bar of the U whereas the second gate 50 forms the second bar and the soul of the U.

In addition, the end of the bars of the second grid 50 are then received in complementary grooves (not visible in the figures) formed in the body 12.

The wiper device 10 may for example be sold as a kit, together with a bucket 52 and, optionally, a broom 54, in particular a flat broom.

The wiper device 10, the bucket 52 and the brush 54 can be made by plastic injection from non-elastomeric materials, in particular polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene (PE) and polyoxymethylene (POM).

As illustrated in FIG. 3, a flat broom 54 comprises a handle 56 for holding the blade, a plate 58 for attaching a cleaning mop 60, the plate 58 being disposed at one end of the handle 56. 58 can be formed of two portions of articulated plates to be folded towards one another, in the extension of the handle 56 of the blade 54.

In addition, a protrusion 61 - in this case a rib - is formed on the upper surface of one of the portions of the plate 58. The projection 61 is formed in such a way that when the two portions of the plate 58 are folded in the extension of the handle 56, the projection 6 1 also extends in the extension of the handle 56.

As illustrated in Figure 4, the mop 60, which has an elongated shape, has two eyelets in the vicinity of each of its ends. To fix the cleaning mop 60 on the plate 58, the plate may comprise two pins 62 (or keys) rotatably mounted on the plate 58 so that:

in a first position of the nipples 62, the latter can be inserted through the eyelets into the cleaning mop 60, whereas

in a second position of the nipples 62, the nipples 62 can not pass through the eyelets.

In the present case, this is achieved by choosing T-studs, the length of which is equal to the length of the eyelets, the eye lets having a width less than their length. Alternatively, the nipples could be in L.

The use of eyelets and nipples 62 allows a particularly simple and intuitive attachment of the mop 60 on the flat mop 54, unlike devices using a snap fastener, in particular.

The operation of the wiper device 10 will now be described with reference to FIGS. 4 and 5. The wiper device 10 is disposed above the bucket 52, the rim of the bucket bearing in the bottom of the grooves 24, 26 formed by the lateral wings 18, 20 of the body 12, in addition, the tongues 28 come to ensure the stability of the position of the device, the curved flange of the bucket 52 being clamped between the tongues 28 and the bottom of the grooves 24, 26 of the lateral wings 18, 20.

To wring the cleaning mop 60 mounted on the platen 58 of the flat mop 54, the two platen portions are folded towards each other, so that the mop 60 hangs at the end of the flat mop 54. The cleaning mop is then introduced into the wiper device 10, into the housing 5 1 delimited by the first and second grids 42, 50. This insertion is favored because the first 14 and second 16 plates are bent at level of their upper end so that the two plates fixed on the body delimit a passage opening 34 flared upwards.

In addition, the insertion of the mop may be guided by the reception of the pins 62 and, if appropriate, the projection 61 of the plate in the grooves 38, 46 formed in the first and second plates 14, 1 6. L insertion of the mop in the housing is thus easier.

Finally, the mop is pressed to the bottom of the housing 51 delimited by the first and second grid 42, 50. Due to this vertical pressure, the second grid 50 is deformed. The portion of the bars of the second grid 50 which initially extended beyond the first guide 42, move towards the housing 51. In other words, the U-shaped section of the housing 5 1 deforms and the soul of the U becomes wider. This displacement of a portion of the bars of the second grid 50 is limited, however, because the end of the bars of the second grid 50 has an extra thickness which abuts against a surface of the groove formed in the body, in which the bars are received.

This deforms the housing to increase the contact area between the cleaning mop 60 and the grid surface of the housing. This ensures a more efficient spin of the mop compared to the known devices of the prior art.

In addition, the protrusion 53, made on each bar of the second grid, allows drainage of the liquid from the spinning of the mop 60 to the bucket 12, avoiding stagnation of the liquid at the second gate 50. The Mopping efficiency of the mop 60 is thus improved.

Of course, the present invention is not limited to the examples and to the embodiment described and shown, but it is capable of numerous variants accessible to those skilled in the art. Thus, the two grids could be of substantially symmetrical shape, the pressure of the brush on these two grids then causing a deformation of the two grids.

In addition, the stop means for preventing the second grid from moving relative to the first grid so that the first and second grids do not intersect more can take other forms. One can imagine that the bars forming the second grid are bent at 90 ° at their end.
