Description

The present invention relates in particular to a flat windscreen wiper blade. STATE OF THE ART Typically, a wiper blade of a window such as the windshield of a motor vehicle includes a wiper blade, usually made of rubber, intended to rub against the window of the vehicle to evacuate water by bringing it out of the driver's field of vision. The broom is carried by an arm which is driven by a motor in an angular back and forth motion. Two wiper blade technologies, a ratchet mop technology, in the form of articulated stirrups that hold the wiper blade in several discrete places, and another flat mop technology (from the English flat blade), in the form of a semi-rigid set that holds the wiper blade along its entire length. In both solutions, the blade is attached to the rotating arm of the wiper by a set consisting of a mechanical connector and an adapter. The connector is a part that is fixed directly to the broom structure or directly to the flat broom, the adapter being an intermediate piece that allows the attachment of the connector on the arm of the wiper. These two parts are connected to each other by a transverse axis which allows their relative rotation. Brush mop technology is well known to those skilled in the art. Application FR-A1-2,681,028 of the Applicant describes for example a windscreen wiper blade asymmetrical. A spreader blade has the advantage of applying the wiper blade against the vehicle window with a pressure that is relatively homogeneous over the entire length of the blade.

DETAILED DESCRIPTION It should be noted that the figures disclose the invention in detail to implement the invention, said figures can of course be used to better define the invention where appropriate. In the following description, the longitudinal or lateral names refer to the orientation of the wiper blade according to the invention. The longitudinal direction corresponds to the main axis of the blade in which it extends, while the lateral orientations correspond to intersecting straight lines, that is to say which intersect the longitudinal direction, in particular perpendicular to the longitudinal axis of the blade. broom in his plane of rotation. For the longitudinal directions, the outer or inner names are assessed relative to the point of attachment of the blade on a brush arm, the inner denomination corresponding to the part where the arm and a half-brush extend. Finally, the directions referenced as upper or lower correspond to orientations perpendicular to the plane of rotation of the wiper blade, the lower denomination containing the plane of the windshield.

Figure 1 shows a flat mop 1 careened according to the invention, that is to say a flat mop equipped with a fairing, the flat mop 1 being here in free position in space, without constraint. The upper part of the blade 1 is formed by the fairing which has an aerodynamic shape which deflects, upward, the air that arrives on the windshield. The fairing thus forms an aerodynamic deflector. The deflection of the aforementioned air generates a bearing force of the blade 1 on the windshield which ensures, in association with a second support force generated by arm pressure, a permanent contact on the windshield and, therefore reliable wiping.

This fairing has substantially the shape of a dihedron formed of two longitudinal walls which meet in the upper part at a summit ridge, the front wall having a hollow aerodynamic shape while the rear wall is substantially flat in the example shown . The inside of the dihedron is hollow so as to leave space for housing elements that form a wiper block of a flat broom, which will be described in detail below. The fairing is made in three parts, which are articulated with each other. The central part, hereinafter referred to as central mount 2, fulfills the functions of connector of a non-ducted flat broom, that is to say that it is on it that the various elements which extend all along the blade 1. With the exception of its center which has substantially parallel vertical walls to accommodate an adapter therebetween, this central mount 2 has the streamlined form aerodynamic baffle described above. It thus comprises two longitudinal side walls 2a, 2b whose upper longitudinal edges are interconnected so that said walls substantially form a dihedron. To this central mount are attached two parts in eccentric longitudinal positions, hereinafter referred to as end covers 3. These two covers have, too and over their entire length, the streamlined form aerodynamic deflector. Each cover 3 thus comprises two longitudinal side walls 3a, 3b whose upper longitudinal edges are interconnected so that said walls substantially form a dihedron.

A first end cover 3 extends inward while the second extends outwardly. The connection between the central mount 2 and each of the end covers 3 is a hinge which pivots about an axis oriented in a lateral or transverse direction, so that the two end covers 3 move in a plane perpendicular to the plane of rotation of the broom. The breakage thus created between the central mount 2 and the end caps 3 prevents the outer and inner ends of the broom are applied against the windshield with a lower pressure than that which is exerted at the level of the central frame , due to a greater distance from their fulcrum relative to the drive arm of the blade.

The central portion of the central mount 2 has a height greater than the rest of the blade, because of its connector function, which makes it possible to house the attachment means of the blade to the drive arm and in particular an adapter.

Figure 2 shows the same blade 1 in a position against a pane, presented here for simplification in the form of a flat surface. The joints between the central mount 2 and the two end covers 3 are closed, that is to say that these covers are positioned in the axis of the central frame, the upper surfaces of these three parts forming a faired surface keep on going. The central portion of the central mount 2 is cut by a window 21 through which the end of a drive arm passes and has a transverse axis on which is fixed the adapter (not shown) which ensures the attachment of the broom to the arm.

Figure 3 shows the broom 1 in exploded view. The central mount 2 comprises longitudinally, on either side, two connecting means or articulation which comprise fingers 4 which extend longitudinally from the body of the frame. These fingers 4 comprise an orifice, oriented laterally or transversely, for receiving a hinge pin carried by the corresponding end cap 3. The cooperation of this axis of articulation with the orifice of the finger 4 allows rotation of the cover 3 relative to the central mount 2, in a plane perpendicular to the plane of rotation of the blade 1.

Below these elements are represented, respectively, a stiffening vertebra 6, a holding member or retainer 7 and a wiper blade 8, all of these three elements forming what will be called thereafter a block of 'wiping. The purpose of the rigidifying vertebra 6 is to serve as a structure for the blade, giving it a curved shape that corresponds to the average curve of the windshield on which the blade moves. Its longitudinal stiffness allows, as for a conventional flat mop, to maintain a sufficient pressure at both ends of the blade, so that the wiping is performed uniformly over the entire surface to be scanned. The holding member 7 constitutes the carrier element, both of the stiffening vertebra 6 and the wiper blade 8. It will be described in more detail, as well as its fixing device on the central mount 2 Referring to FIGS. 6 to 8, the wiping blade 8 is a conventional elastomeric material blade which is carried by the holding member 7 and whose purpose is to remain in constant contact with the windshield.

Figure 3 shows, in addition, two end caps 9, whose function is to join the three previous elements at their ends and lock them longitudinally. Each end piece 9 also has a longitudinal abutment 94 against which abuts a bearing face carried by the corresponding end cap 3. This cooperation of the longitudinal stop and the bearing face of the cover prevent the three elements of the wiping block from extending longitudinally when the cover pivots relative to the central mount 2 and thus forces them to bend so that they follow the curvature of the windshield. The device 14 for fixing these three elements is illustrated in detail in FIG. 4, whereas the device 15 for co-operating the end of these elements with the end cap 9 is illustrated in FIG. Figure 4 shows first of all the stiffening vertebra 6 which has the shape of a thin metal blade, of parallelepiped shape, and which has a notch 61 in the middle of each of its longitudinal edges.

The holding member 7 comprises, in turn, four cutouts 71 which are positioned longitudinally side by side at its middle, and which are made, two by two, on the upper longitudinal edges of the member 7. They have intended to pass hooks extending laterally in the lower part of the central frame 2, to ensure, through the stiffening vertebra 6, the attachment to the central frame of the wiper block, as will be explained more in detail with reference to Figures 7 and 23.

In Figure 5, we see the longitudinal end of one of the end caps 3 and the end cap 9 associated. One of the ends of the stiffening vertebra 6, the holding member 7 and the wiper blade 8 are also seen. The end cap 9 has a substantially hollow parallelepipedal shape on the outside, and it internally comprises two housing or cavities 92a, 92b (respectively upper and lower) oriented longitudinally and intended to receive the end on the one hand of the stiffening vertebra 6 and on the other hand, the wiper blade 8. A third housing 92c can in addition, be provided for the introduction of the longitudinal end of the holding member 7. Each housing 92a, 92b comprises an open longitudinal end and a closed longitudinal end. The housings 92a, 92b are formed by internal walls at the end cap 9 which reproduce, by extending, the shape of the stiffening vertebra 6 and the wiper blade 8. There is thus continuity in maintaining the stiffening vertebra 6 and the wiper blade 8 when they pass from the holding member 7 to the end cap 9. Vertical ribs (not visible in the figure) are also positioned longitudinally in the upper cavity 92a of the nozzle 9, that is to say that which receives the stiffening vertebra 6, to reduce the height of the cavity and come to press the vertebra once it is inserted therein . Finally, the side walls of this cavity 92a are flexible to be able to move apart during the introduction of the vertebra 6 while resisting this bending to compress laterally the vertebra and cause its jamming in the tip. This prevents the disconnection of the tip 9 once it is installed at the end of the blade. The end cap 3 comprises at its free end visible in FIG. 5 two substantially parallel lateral wings 30 defining between them a space configured to receive the end cap 9. The longitudinal ends of these wings 30, situated on the side of the free end of the cover 3, are connected together by a transverse flange 3c which is intended to cooperate with the aforementioned abutment 94 of the end piece 9, as will be described in more detail in the following with reference to FIG. 24. FIG. 6 illustrates the circulation of the air in the vicinity of a broom 1 according to the invention. The blade 1 is shown in section along a plane transverse to its longitudinal direction, at the half-blade located on the inside. The air arriving on the windshield is deflected upwards by the fairing of the central mount 2 (or that of the end cap 3) and passes between this fairing and the arm 10 (since the cut is made on the side inside). It can be seen here that the lower longitudinal edges of the longitudinal lateral walls 2a, 2b of the frame 2 are not situated at the same position in height or vertical direction (the horizontal direction being substantially parallel to the windshield and therefore the substantially perpendicular vertical direction to the windshield), the lower edge of the wall 2a being located lower than that of the wall 2b. In other words, the lower edge of the wall 2a is located substantially in a first substantially horizontal longitudinal plane P6 which is at a distance and here below a second substantially horizontal longitudinal plane P7 substantially passing through the lower edge of the wall 2b. It is the same for the lower edges of each of the end caps 3.

The wiper block, that is to say all three elements, stiffening vertebra 6, holding member 7 and wiper blade 8, appears under the fairing of the central mount 2, in the offset position by relative to the summit ridge 2d of this fairing, on the side of the front wall of the air deflector. This positioning corresponds in fact to the middle of the lower ends of the walls of the fairing since they are in the extension of the lateral faces of the central frame at its window 21, so at its widest point. This figure also shows the arrangement of the three elements of the wiping block: the holding member 7 has, in cross-section, the shape of a closed parallelepipedal tube 72 of which extend, downwards, two hooks 73 oriented towards each other, thus forming a parallelepiped cavity open downwards. The stiffening vertebra 7 is slid into the upper tube 72 which it fills while retaining the ability to slide longitudinally inside, while the wiper blade 8, better visible in FIG. 8a, is carried by its upper part, or heel 81, which has a substantially rectangular shape, by the two hooks 73. The lower portion 82 of the wiper blade 8 extends from the lower cavity of the holding member 7 towards the windshield and is ends with a terminal portion 83 which classically has an inverted fir shape.

Figure 7 shows in perspective, in bottom view, the central mount 2, with the fixing means of the wiper block, which serves as a connector. The portions of the side walls 2a, 2b, situated on either side of the window 21, extend downwards until they exceed the space allocated to the adapter 5 and each comprise, at their lower end, two hooks. 23. Each hook 23 of a side wall 2a is substantially facing a hook 23 of the other side wall 2b, and extends towards it. The fastening means thus comprise two pairs of lateral hooks, the hooks of one pair being at longitudinal distance from the hooks of the other pair. Each hook 23 defines a longitudinal notch 23a configured to receive the vertebra 6 by longitudinal sliding. In the example shown, the transverse plane P passing through the axis 25 passes substantially between the two pairs of hooks 23 and equidistant from them. this. The longitudinal extension of these hooks is slightly smaller than that of the cuts 71 which are made in the holding member 7.

As for their lateral extension it is such that the spacing between them is greater than the depth of the cuts 71, so that these means can be entered into the internal cavity of the central frame by returning them from below. Finally, this spacing is less than the width of the holding member 7, so that the latter can rest on the hooks 23 after implantation of the wiper block. It is therefore seen how the assembly of the wiper block on the central mount 2, which acts here as a connector: the holding member 7, possibly equipped with its wiper blade 8 but without the stiffening vertebra 6 is introduced, from below, into the internal cavity of the central mount 2, by passing the hooks 23 in its cutouts 71. At least one substantially horizontal longitudinal plate forming a vertical stop (not shown in Figure 7) generally extends above the hooks 23 to serve as a limit to the introduction of the holding member 7 in the inner cavity in the lower part of the central mount 2. In this position, the upper tube 72 of the retaining member is aligned with the upper face of the hooks 23, which creates a groove continuity for the passage of the stiffening vertebra 6. The operator then slides this vertebra into the upper tube 72, from one of the ends longitudinal members of the retaining member, through the central frame 2 by sliding on the hooks 23 at the cutouts 71 of the retaining member, then pushing it to the other end of the retaining member . The wiper block is then immobilized vertically by the retaining member which rests on the hooks 23 and longitudinally by the interlocking of these same hooks 23 in the cutouts 71 of the holding member 7.

FIG. 8 illustrates three alternative embodiments of the holding member 7, in which the upper tube 72 is constituted by a parallelepiped whose cross-section rectangle is either fully closed (FIG. 8a) or open on its underside (FIG. 8b), is open on its upper face (Figure 8c). In all three cases, the tube remains sufficiently closed so that the stiffening vertebra 6 is properly held in the tube 72. The three variants, however, retain the same shape for the lower hooks 73 which serve to hold the wiper blade 8. In these embodiments, small ribs 74 are noted which extend longitudinally on the inner surface of the tube 72 to compress the vertebra 6 and maintain it longitudinally once it has been forced into this tube. . Similarly, the heel 81 of the wiper blade 8, which is inserted by longitudinal sliding between the hooks 73 of the holding member 7, comprises longitudinal protrusions which rub against these hooks during the introduction of the blade in order to ensure a certain longitudinal and lateral retention of this blade.

Figures 9 and following describe in more detail the articulation between the central mount 2 and the end caps 3. In Figure 9, we see the longitudinal walls, 2a at the front and 2b at the rear, which form the dihedral of the aerodynamic deflector of the central mount 2 by joining on a summit ridge 2d, this dihedral ending longitudinally by a transverse wall 2c which closes the dihedron. From this transverse wall 2c extends a finger 4 of substantially parallelepiped shape, which is traversed by an orifice 41 intended to serve as a support for the axis 31 which allows the pivoting of the corresponding cover 3.

FIG. 10 shows, in section, said end cap 3 mounted on the central mount 2 with a cover articulation pin 31 which extends from one of the side walls of the cover and comes through the orifice 41 finger 4.

Referring to Figure 11 we see the inside of the part of the cover 2 which cooperates with the central mount 2. Inside the dihedron formed by the longitudinal walls 3a and 3b of the cover extend two reinforcements 32a and 32b which are based on these longitudinal walls and which extend to form two flat faces, both oriented in a vertical plane and facing each other. From these two flat faces extend two studs 31a and 31b which are aligned and together form the axis 31 on which the hood 3 rotates. The gap left between the two tenons 31a and 31b is sufficiently small and, in any case, cause less than the length of the orifice 41, so that these tenons hold the finger 4 once mounted, and sufficiently wide so that the finger can be inserted by separating the two longitudinal walls 3a and 3b from each other thanks to the elastic flexibility of the hood. The upper face 43 of the finger 4 can be chamfered to facilitate this insertion. It is also noted in Figure 11 that the upper longitudinal edges of the walls 3a, 3b are interconnected to form an upper longitudinal edge 3d of the hood. FIG. 12 shows, in bottom view, the central mount 2 and an end cap 3 assembled, the finger 4 being positioned between the two reinforcements 32a and 32b and, in a non-visible manner, the two tenons 31a and 31b being inserted in the hole 41 of this finger. Alternatively, not shown, the finger 4 may be carrying two pins extending on either side of its side faces and the reinforcements of the cover 3 comprise in this case, holes in which insert said pins.

Referring now to Figures 13 to 16 we see a device for limiting the angular amplitude of the joint between the central frame 2 and the end caps 3. Indeed, an angle too large would be unfavorable to a good wiping of the windshield in that the pressure of the broom on the windshield would not be evenly distributed. The maximum acceptable angle for the break between the central mount 2 and each end cap 3 is, as seen in Figure 13, 165 ° for example. It is therefore appropriate to position stops on the two elements to prevent this value from being exceeded. The most favorable positioning of these stops to obtain this angular limitation, is to position them as close as possible to the axis 31 of pivoting of the cover 3. FIG. 14 shows a first embodiment for the positioning of these stops, in which the cover 3 comprises, in the internal space defined by its longitudinal walls 3a, 3b, a projecting stop 33 which extends above the finger 4. This stop 33 is configured to cooperate with the finger 4 to define a position extreme of pivoting of the cover 3 vis-à-vis the mount 2. The stop is formed by a rib 33 which extends transversely between the inner faces of the longitudinal walls 3a, 3b of the cover 3. The lower free end of the rib 33 is chamfered to define a bearing face. For better cooperation with this abutment, the finger 4 has at its free end 43a forming a stop chamfer, whose plane is aligned with the lower plane of the rib 33 when it is abutted against the finger 4 is that is, when the cover 3 is in its maximum angular extension. Figures 15 and 16 describe, respectively in section and in perspective, another embodiment for the positioning of these stops. The cover 3 here comprises a protruding abutment 33 'formed by a substantially longitudinal rib. This rib 33 'is oriented from top to bottom and extends from the summit ridge of the end cap 3. It thus extends here from the connection zone of the upper longitudinal edges of the longitudinal walls 3a, 3b hood. The free lower end of the rib 33 'is chamfered to define a bearing face. The finger 4 here has an extra thickness 43b on its upper face 43 which faces the rib 33 '. This extra thickness 43b, of substantially parallelepiped shape aligned with the longitudinal direction and with the direction of elongation of the finger, comprises, as before, towards the outside, a chamfered portion whose plane is aligned with the lower plane of the rib 33 ' when it is in abutment against the finger 4. In the two cases shown in Figures 14 to 16, the rib 33, 33 'forms a projecting stop. The free end 43a of the finger 4, bearing the chamfer, forms a protruding abutment and the extra thickness 43b also forms a projecting abutment. The frame 2 and the covers 3 thus cooperate together by protruding abutments.

Figures 17 and 18 describe how the two ends of the central frame 2 and the cover 3 corresponding cooperate. FIG. 17 shows the transverse wall 2c which closes the dihedral of the frame 2 and from which the finger 4 extends. In this embodiment of a wiper blade, this wall 2c defines a peripheral rim 102c which resumes the shape of the longitudinal walls 2a, 2b of the central mount 2 by reducing it in a ratio homothety slightly smaller than 1. This rim 102c is similar to a groove in the outer periphery of the frame 2. It extends longitudinally from the end of the longitudinal walls 2a, 2b over a relatively short length, between 1 and 5 mm. The flange 102c extends over the entire transverse extent and the vertical of the longitudinal walls 2a, 2b. Also, the longitudinal end of the end cap 3 has a recessed shape and itself defines a peripheral flange 103c which can accommodate the peripheral flange 102c of the central mount 2. The flange 102c thus forms a male flange engaged in the flange 103c which is a female flange. The flange 103c takes the shape of the longitudinal walls 3a, 3b of the cover 3. In this way, and taking into account the length chosen for the peripheral flange 102c, the latter, engaging in the longitudinal end of the cover end 3, is covered by the latter, that the joint is in the position where the shrouds are aligned or that it is in the position of maximum angular opening. This configuration provides aerodynamic continuity to the fairings of the central frame 2 and the end caps 3, preventing the air flowing on the windshield from escaping between them. As a result, it makes it possible to improve the aerodynamic efficiency of the blade by avoiding degrading the level of pressure applied to it by the air. Figure 19 shows the central mount 2 in a longitudinal direction. In this figure we see, upstream of the window 21 of the frame, the dihedral which is formed by the longitudinal walls 2a and 2b and the summit ridge 2d where they meet. It can be seen in FIG. 19 that the finger 4 has an axis of elongation extending in a longitudinal plane P3 which is substantially perpendicular to said corresponding axis of articulation 31 and which passes substantially through the summit ridge 2d of the dihedron. It can also be seen that the plane P3 is parallel and at a distance from the median longitudinal plane P1 of the window 21. This plane P1 passes through the middle of the hook fastening means 23. It may be noted that the edge 2d extends substantially in parallel and away from plane P1. It is located in the plane P3. We also see in Figure 19 the fastening means of the wiper block. We find in particular the hooks 23 of support member 7 which are part of a parallelepipedal assembly which extends longitudinally over the entire length of the hooks 23 and in which are dug the two notches 23a, positioned symmetrically. on either side of the lower edges of the dihedron formed by the side walls 2a and 2b. These notches 23a form a guide for the passage of the stiffening vertebra 6 during the fixing of the holding member 7 on the central mount 2. The upper wall of this parallelepiped forms, in turn, the longitudinal plate forming a vertical stop to the introduction of the holding member 7 in the internal cavity of the central mount 2. For reasons of optimization of the aerodynamic performance of the fairings of the central frame 2 or the end caps 3, the summit ridge 2d is offset laterally downstream (in relation to the flow direction of the air flow) relative to the median plane P1 of the wiping block 10 or the center of the central mount 2. For reasons of better mechanical strength , the finger 4 is positioned substantially below the dihedron formed by the longitudinal walls 2a and 2b, that is to say at a place where the density of material for this dihedron is the strongest. Referring to Figures 20 and 21, there is shown a particular embodiment of a broom adapted to small wipers. In this mode, the length of the end covers 3 is small compared to that of the central mount 2. This type of windscreen wiper is suitable for windows of small dimensions, and therefore of low curvature, as, for example, For example, a rear window of a motor vehicle. Therefore, it is not necessary to implement a joint that shifts the axis of the end caps 3 of that of the central frame 2. On the other hand, for reasons of economy on the logistics, it is interesting for the manufacturer to reduce the number of parts references. For this the invention recommends keeping a single model for the central mount 2, and therefore the same adapter 5 for several models. Therefore, it becomes possible to provide an end cap 3 which, while retaining the same fastening means on the central mount 2, comprises a locking device of its rotation relative to this central mount. FIG. 20 shows, between the two reinforcements 32a and 32b, the side walls 3a and 3b and the tenons 31a and 31b, which normally serve as a hinge pin, a hood rib 34 extending longitudinally. on both sides of the axis formed by the two tenons. It is positioned and extends vertically so that, in the position of the assembled cover, it is in contact against the upper face 43 of the finger 4 and forms a protruding stop preventing rotation of the cover 3 around said finger 4. FIG. 21 shows a short cover 3 mounted on the central mount 2. Its inner end is supported against the outer end of the central mount and, not visible in the figure, the hood rib 34 blocks any rotation of the cover in a meaning or in the other. It may be noted, however, that the rib 34 may extend only on one side with respect to the tenons 31a and 31b while preventing the hood from rotating in the direction of a closure, the locking being opened by the cooperation of the ends longitudinally contiguous hood 3 and the central mount 2. Figures 22 and 23 show, respectively disassembled version and assembled version, an alternative embodiment for the fairing of a blade for a small wiper. Unlike FIGS. 20 and 21, the fairing of the two end covers 3 is here produced in one-piece fashion with that of the central mount 2. The devices serving a joint, such as the finger 4 or the tenons 31a and 31b are then deleted. We thus gain in ease of production of the hoods. And for reasons of homogeneity of appearance of the range of wiper blades produced, 2x grooves are drawn on the common cover, at the level where the joints between the central frame 2 and the end covers would be located 3. Figure 22 also shows the inner portion of the central mount 2, it is integral with end caps 3 or not.

Given the elongation of this central mount 2, it may be necessary to place reinforcing ribs or stiffening 24 within the dihedron formed by the two longitudinal walls 2a and 2b. The invention recommends to give them a cross-shaped, whose common axis is oriented vertically, that is to say that it extends from the edge, towards the base of the dihedron. Due to the flare of the dihedral downwards, these reinforcing ribs 24 constitute ideal support points for ensuring the ejection of the central mount from the injection mold, these parts being generally made of polymer material and made by a hot injection method. According to the invention, it is also possible to provide at least one rib, preferably two, extending substantially transversely to the direction of extension of the central mount 2. The ribs 24 may thus comprise at least one mark of a ful point for the ejection of the frame 2 of a manufacturing mold. This mark is generally located on the lower free edge of the rib 24. At least one mark may be located in the junction zone of the intersecting ribs visible in FIG. 22. In FIG. 24 is illustrated the junction between the end piece end 9 and an end cap 3, the latter being shown in section along a median longitudinal plane. As indicated above, the end tip 9 has a substantially parallelepipedal shape having an opening on its face which is oriented towards the central mount 2. It thus comprises an upper face 91 and a lower face 92 which are connected by means of side faces 93, and a closed end face which is located on the opposite side to the central mount 2. As indicated with reference to Figure 5, the inside of the end piece has two longitudinal internal housing 92a, 92b forming slides for the stiffening vertebra 6 and for the wiper blade 8, respectively, and a housing 92c for receiving a portion of the member 7.

On the upper face 91 of the end piece 9 is positioned a projecting stop 94, having a ramp shape which rises from this upper face away from the brush. The abutment face, which is oriented transversely, is directed towards the outside of the blade, that is to say in a direction that is substantially parallel to the axis of extension of the end cap 9 This abutment 94 is intended to cooperate with the transverse flange 3c carried by the end cap 3 which is associated with the end cap 9. This abutment 94 is intended to limit the bending of the valve member. 7 when the curvature of the windshield increases and, by reducing the angle between the central mount 2 and the end cap 3, to control the radius of curvature of the holding member 7. It thus forces the while remaining more rectilinear, to maintain significant support on the windshield in the center of the blade, which provides a more regular wiping during the rotation of the wiper blade. As shown in the figure, the transverse flange 3c of the cover 3 which cooperates with the projecting stop 94 is formed by the end wall of the end cap 3. In alternative versions, it consists of a rib extending transversely between the two side walls 3a, 3b of the end cap 3, upstream of the end face of the cover 3. This configuration makes it possible to have an alignment for the end faces of both the cap and the end piece. end, which improves the aerodynamic performance of the broom. Figures 25 and 26 show a variant for the arrangement of the respective abutments of the end cap 9 and the end cap 3. A projecting abutment 94 'is, here, positioned on the inner side, on each side face 93 of the end cap, with a ramp shape and an orientation similar to the projecting stop 94 described above: the ramp rises from the side face 93 in the outer direction with a transversely oriented abutment face relative to the longitudinal direction of the broom. The end cap 3 comprises, in this case, at its lateral flanges 30 which extend vertically at the lower end of the longitudinal walls 3a and 3b, second projecting stops 35 adapted to cooperate with the projecting abutments. 94 'of the end cap 9. The stops 35 are projecting on substantially parallel inner faces of the lateral wings 30. To this end they have the shape of a ramp extending from the corresponding vertical wall but this time in the inner direction. Their abutment faces are also oriented transversely to the longitudinal direction of the blade. Referring to Figures 27 to 29, we see the end portion of an end cap 3, short distance from its outer end. Between the longitudinal walls 3a and 3b forming a dihedron extends transversely a transverse guide wall 36 which rests on the entire height of the longitudinal walls. The wall 36 provides stiffening of the hood. It extends here between the lateral wings 30 of the walls 3a, 3b. This transverse wall 36 is cut in a substantially rectangular shape to serve as guiding means for the wiper block, that is to say substantially to the holding member 7 which contains the stiffening vertebra 6 and which carries the blade The rectangular shape is further open downward to allow passage to the wiper blade 8. As a result, the transverse wall 36 is downwardly in the form of two hooks. guiding sides 37 extending from its vertical portions in two horizontal parts positioned opposite each other and which are separated by a space substantially corresponding to the thickness of the holding member 7 at this level. Upwards, the transverse wall 36 is a wall connecting the vertical parts of the two hooks 37. These two hooks 37 form support means for the holding member 7 and the rectangular cut in the transverse wall 36 serves as a means guiding this member for its sliding in the cover 3, when the cover 3 is articulated with respect to the central mount 2.30 FIG. 28 shows, in particular, the shape of the rectangular cutout made in the transverse guide wall 36. The three unopened sides of this rectangle comprise, substantially in their middle, protuberances in the form of lugs 38 which project towards the inside of the rectangle. These protuberances form almost point-specific support points for the holding member 7 when it is introduced into this rectangular cutout. These punctual supports are used to compensate for manufacturing tolerances and, because of their punctuality, allow better guidance and easier sliding. The vertical part of each hook 37 here comprises, substantially in the middle, a lug 38 whose free end is configured to cooperate with the member 7. The upper part of the wall 36, connecting the upper ends of the vertical parts of the hooks 37, also comprises, substantially in the middle, a lug 38 of punctual support on the body. The lugs 38 have here a rounded overall shape. FIG. 29 shows the guide hooks 37 for supporting the holding member 7, the longitudinal thickness of which is greater than that of the transverse wall 36. This extra thickness is positioned on the side of the central mount 2 and has the shape of a ramp 39 thickening from the lower edge of the longitudinal wall 3a or 3b of the end cap 3 to join the transverse wall 36 at the upper edge of the hook. The ramps 39 comprise substantially co-planar guiding faces. The ramps guide the end of the holding member 7 when it is introduced into the transverse wall and facilitate its passage through the wall during its introduction. Figures 30a and 30b show the central mount 2 in plan view, with its window 21 in which is positioned the adapter 5, intended to be mounted on the arm 10 extending respectively to the right or to the left of each of the figures. It can be seen that the size and the shape of the window 21 are adapted to a positioning in one direction or the other of the adapter 5. In other words, the window 21 is configured to allow the mounting of the adapter 5 and snapping onto the shaft 25 in a first position in which a first longitudinal end of the adapter is oriented towards a first longitudinal end of the window, as well as in a second position in which the first longitudinal end of the adapter is oriented toward an opposite second longitudinal end of the window. The opening of the window 21, located at its upper end, is delimited by a peripheral edge of generally rectangular shape. The length of the window 21 leaves enough room for the arm 10, which extends beyond the length of the adapter 5, to rotate without interfering with the side of the window which is opposite the direction of the extension of the arm .

Preferably, the window 21 has a double symmetry, both longitudinal (with respect to a median transverse plane P2), the adapter 5 being in general also subject to a longitudinal symmetry, that transverse (with respect to a median longitudinal plane P1) to facilitate the assembly of the blade 1 on an arm 10 which rotates in one direction or the other.

This double symmetry configuration makes it possible to use the same central mount 2 for the two brushes, that the two brushes (left and right) wiping the windshield of a vehicle move in a coordinated manner or that they are counter.

FIG. 31 shows, in section along the median longitudinal plane P1, an adapter 5 installed in a central mount 2. The window 21 of the central mount 2 is traversed laterally by the transverse hinge axis 25 which connects the two vertical faces parallel 22 of the center of the central frame 2 and which serves as support for the adapter 5.

The adapter 5 has in its center, as can be seen in Figure 32, a cylindrical housing 51 for receiving the transverse axis by snap elastic. The adapter 5 has substantially a parallelepipedal shape elongate in the longitudinal direction with two lateral wings 52 interconnected by a medial portion which defines the cylindrical housing 51. It also comprises, on each lateral flange 52, a longitudinal extension 52a of which the object is to serve as a stop to limit the rotation of the adapter 5 in some cases of use. However, to avoid breaks in one of the elements of the adapter during untimely manipulation in rotation, the invention proposes to raise the vertical position of the axis 25 on the parallel vertical faces 22 of the center of the central mount 2, so that it allows an angular rotation of the adapter in which the longitudinal extensions 52a do not interfere with the fastening means of the wiper block, namely the hooks 23. For this, the radius R1 of the adapter 5 at the longitudinal extensions 52a, which is in the range of 15 mm, and more generally between 10 and 20 mm, is shorter by about 1 mm than the radius R2 on which is the most central point of the hooks 23 for fixing the holding member 7 (see Figure 31). The radius R1 is the maximum radius of a first circumference centered on the axis 25 and passing substantially through the extensions 52a of the adapter 5, and the radius R2 is a maximum radius of one second circumference centered on the axis 25. and passing substantially through the upper ends of the hooks 23. If the two longitudinal extensions 52a do not interfere with the hooks 23 and allow unobstructed rotation to the adapter 5, it is nevertheless necessary to limit this rotation to avoid angular deflection too big to the broom, which could lead to the breakage of one of its elements. For this, a lug 53 extends laterally from the upper edge of one of the lateral wings 52 of the adapter 5, on the opposite side to its other side wing, which allows it to abut against a peripheral edge of the window 21 for example to limit the angular displacement of the adapter 5 about the axis 25. The inner faces 22 have notches 22a for receiving and moving this lug 53. Referring now to Figures 33 to 35 , we see the inside of the window 21 of the central frame 2, which extends longitudinally between the side walls 2a, 2b of this frame. On either side of this central portion extend the longitudinal portions before 2a and rear 2b, with reference to the direction of air flow. As indicated above, the transverse axis of articulation 25 connects the two parallel side walls 22, so as to support the adapter 5 which is fixed on it by snap-fastening or resilient snap-fastening Due to the relatively large elongation of the window 21, the portions of side walls 2a, 2b situated at the level of the window may present a certain fragility during their handling and the invention recommends adding means 26 for connecting and stiffening between the internal lateral faces 22 of the window 21, here in the form of sleepers 26 which each have an elongate bar shape. As shown, these crosspieces 26 extend parallel to the hinge axis 25 by being positioned substantially at the same height as this axis, and substantially in the middle of the distance between the axis 25 and the longitudinal end of the window 21. These crosspieces 26 are formed by bridges of material connecting the two side faces 22. They are here of the removable type, that is to say they can be removed. They can be breakable or cut or dismountable, they can in particular be unclipped.

They present here sections to break, namely a zone of weakness or weakness at each of their ends, so as to be broken at the faces 22, without leaving a protrusion that would interfere with the rotation of the adapter 5. Indeed the presence of two crosspieces 26 on the same central mount 2, which corresponds to a configuration at the output of manufacture, is not adapted to the commissioning of such a central mount because one of them would limit, unduly, the rotation of the adapter 5. It is appropriate, when mounting a wiper blade to choose in which direction this mount is going to be installed on the arm of the wiper. Depending on this choice, one of the crosspieces 26 is broken, which gives the necessary freedom of rotation to the arm and its adapter 5 in the central frame. As seen in Figure 35, the second cross is retained because it does not interfere with this rotation. The invention thus provides a simplification in the production of central frames 2 and in their logistics since it is of a single model, which adapts to all the directions of rotation of a wiper blade, by means of the pre-break of one of the two crosspieces 26. The presence of the two then of a single crosspiece 26 gives the necessary rigidity to the parallel side walls 22, firstly during transport for its transport to the assembly site, then during of its use on a windshield. The two crosspieces 26 are here arranged symmetrically with respect to the transverse plane P2 passing substantially through the middle of the window 21. In addition, the window 21 has at each of its longitudinal ends a cutout 21a, essentially transverse, which extends longitudinally the cutting of the window 21. In this cutout is positioned a transversely oriented axis 27 which can act as axis of rotation or support axis to a closure cap, as will be explained later with reference to FIGS. 36 to 43. Figure 36 shows a central mount 2 in which the window 21 is partially closed by two closure caps 28a and 28b. Indeed, while the window 21 must be long enough to be able to insert an adapter 5 and the arm on which it is attached, its opening upwards is harmful after the establishment of these elements, both for reasons aesthetic than for aerodynamic reasons, the hollow of the window can create turbulence in the air flowing on the windshield. The invention therefore recommends the installation of two closure caps 28a, 28b which cap the window 21 and which close the upper face of the central portion of the central frame 2, to form a central cowl mount. Given the presence of the arm and the adapter 5 which do not have symmetry in a transverse plane, the two openings left free at the ends of the window 21 are not identical or symmetrical. There is therefore a front closure cap 28a which is positioned outwardly relative to the arm of the brush and a rear closure cap 28b, which is positioned on the inner side. Thus, a first cowling 28a is configured to close a longitudinal end portion of the window 21 and the second cowling 28b is configured to seal an opposite longitudinal end portion of the window. The introduction of these covers can be done in two different ways. As shown in the figures, the front cover 28a is rotatably mounted about the axis 27 of the front cutout 21a, while the rear cover 28b is fixedly mounted on the axis 27 which passes through the rear cutout 28b. Figures 37 and 38 thus show the rotational capacity of the front cover 28a about its axis 27. In Figure 37 the front cover is raised and reveals the longitudinal space which is released to allow the insertion of the arm 10 carrying the broom in the window 21 and its passage around the adapter 5. Figure 38 shows the closed front cover and the continuity of the surfaces between the upper face of the central frame 2, the front cover 28a and the arm 10 carrying the blade. Finally, Figure 39 shows, in bottom view, the front cover 28a in position in the window 21. Figure 40 shows in more detail the shape of the front cover 28a. It comprises an upper face 281a whose shape (here not flat) is shaped to extend the shape of the upper face of the central mount 2 and provide aerodynamic continuity between these two elements. The lower face 282a is formed by stiffeners which are crossed so as to give rigidity to the workpiece and which extend vertically to meet the upper face 281a. At the front, that is to say towards the outside of the wiper, the upper face 281a ends with a transverse cylinder 283a which is open on a sector of limited amplitude. This cylinder has for its internal diameter a value slightly greater than that of the axis 27, so that the axis 27 can serve as an axis of rotation for the front cover; the opening sector of this cylinder is such that the axis 27 can pass into this sector by snap elastic and then remains there after snapping. Finally on the sides of the front cover there are two legs 284a vertically oriented which extend from the upper face 281a. At the rear of these two legs 284a also extend vertically two second legs 285a. At each side of the cowling, between the legs 284a, 285a, further extends a hook 286a also extending vertically. The hooks 286a are elastically deformable and are intended to cooperate by elastic snap-fastening with means complementary to the frame 2. In FIG. 39, we see the first two tabs 284a which open into the window 21 and which are nested in guides or recesses. 29 of the window 21. These guides are formed, on the one hand by the lateral faces 22 of the central part of the central mount 2, and on the other hand by partitions 29a parallel to these faces, shifted inwards of the window 21, these parallel partitions 29a being attached by small transverse partitions 29b to the side faces 22 to close the recess forming a guide. The first legs 284a serve to position the cover 28a in the window 21. The hooks 286a cooperate with the lower ends of the partitions 29b to ensure the hood lock in its mounting position. Furthermore, the longitudinal end of one of the stiffeners of the cap 28a, opposite the cylinder 283a, forms a means 282a 'for supporting and retaining the adapter 5 and / or the arm 10.

Figures 41 to 43 show the rear cover 28b and its installation in the window 21. The elements of the rear cover having the same function as similar elements of the front cover are designated by the same reference numerals, the letter is replaced by a letter b; they are not described again. Figure 42 shows the direction in which the establishment of this cover. While the front cover 28a was attached to an axis 27 and mobile in rotation around it, the rear cover 28b is implanted by a vertical translation to be positioned by latching in a fixed manner.

Therefore, as can be seen in Figure 43, the cylinder 283b of the rear cover has an open sector whose opening is oriented downwards. The rotation around this axis 27 is annihilated by the presence of the first legs 284b whose opposite side to the cylinder 283b cooperates over its entire height with the small transverse wall and blocks any rotation.

As a result, the presence of hooks is no longer necessary. Similarly, the end of the window 21, which is illustrated in FIG. 41, is simplified relative to that of FIG. 39, and comprises only a guide 29 for housing only the first plates.

Referring now to Figure 44, there is shown a central mount 2 connected to a drive arm 10 of the wiper blade. This arm has, in known manner, an end curved in an arc or a U in which is positioned the adapter 5 which serves to allow the assembly of a same model of broom on several types of arms and make it fit to be mounted on various vehicles. The arm 10 and the adapter 5 rotate, as indicated above, around an axis of articulation 25 which extends between the two parallel lateral faces 22 of the central mount 2 and on which closes the adapter. The arm 10 must be able to rotate about the hinge axis in the direction away from a large angle to allow mounting of the blade on the arm, but it is also advantageous to give it a certain degree of freedom in rotation in the direction of the approach to the broom so that the latter adapts perfectly to the curvature of the windshield. To this end, the invention recommends to raise vertically the hinge pin 25 which is here is located in a longitudinal plane P4 located above a parallel longitudinal plane P5 substantially passing through the upper ends of the longitudinal end portions the mount, that is to say by the upper edge 2d (see also Figure 31). Plans P4 and P5 are here substantially horizontal. As described in the foregoing, the upper longitudinal edges of the side walls 2a, 2b are spaced from each other at the window 21 to define peripheral edges of this window. These peripheral edges each have a convex curved shape and have upper (C) ends located above the P4 and P5 planes. In this way, the arm 10 can move closer to the blade and make a negative angle with its longitudinal direction (with reference to the movement for mounting the blade which is taken as a positive direction of rotation). This angle is preferably in the range of 3 to 4 degrees and, in any case, is between 0 and 5 degrees.

FIG. 45 shows in view from below an end cap 3 with at one of its longitudinal ends reinforcements 32a and 32b as explained with reference to FIG. 11, and at the other end a transverse guiding wall 36 for the passage of the holding member 7. Given the elongation of this piece, which can be relatively large in the case of large size brushes, the length of the central frame 2 is preferably the same for all models of brooms, the invention recommends installing transverse stiffening ribs 310 at several points of the end cap 3. These ribs 310 have essentially a triangular shape to fit the dihedral shape formed by the two longitudinal walls 3a and 3b of the hood. They are positioned longitudinally equi-distributed, the largest number being positioned between the reinforcements 32a and 32b and the guide wall 36, an additional transverse rib being positioned beyond this transverse guide wall. In addition to their function of stiffening the end cap 3, these ribs 310 have a fulcrum on their underside configured to withstand the pressure that is exerted by the ejector of an injection machine during the production of the hood . In a particular embodiment, not shown, the rib is a double rib formed by two intersecting ribs, the point of support for the ejector being then positioned at the junction point of the two ribs.

FIG. 45 also shows that the median longitudinal plane P1 of the hinge means 31a, 31b of the substantially vertical cowl is substantially parallel and at a distance from a second median longitudinal plane P9 of said guide means 36, 37.

Figures 46 and 47 show two versions of central wiper blades 2 and two end covers 3 which are attached to said central mount. For reasons of simplification of production and logistics, the invention recommends to homogenize the central frames 2, which are the most complex parts, and to vary the length of the end caps 3 to adjust the broom 1 to the appropriate length for a particular application. Whatever the broom to provide a given vehicle, the central mount 2 is identical, and therefore interchangeable. Given the average lengths observed on the wipers of the vehicles in service, the length chosen for the central frame is typically between 15 and 30 cm. Furthermore, it is appropriate to respect relative dimensions between the central mount 2 and the end covers 3, so that the angle formed by these covers with the central mount remains in relatively low values. Otherwise, the wiping performed by the central frame 2 and / or that performed by the end caps 3 will not be of good quality because the contact will not be made over the entire length of the element concerned or, s it is done, the pressure on the windshield will not be homogeneous. To avoid this inconvenience, the invention recommends keeping a ratio between the length of the central frame and the total length of the blade within certain limits. After examination, the results of various wiping tests, the invention recommends a value between 20 and 70% for the ratio between the half-length L1 of the central frame 2 (that is to say, the distance between the transverse plane P2 passing through the transverse axis of articulation 25 and another transverse plane P8 passing through the pivot axis 31 of the end covers) and the half-length L2, L2 'of the broom (that is, that is to say the distance between the first plane passing through the transverse hinge axis 25 and the longitudinal end of the end cap 3). Preferably, this ratio is between 25 and 65% and for example between 27 and 59%. The invention also proposes a method for mounting fairings for flat blades with wiper blades, in particular for vehicles, comprising a step of mounting a short fairing 1 and a step of mounting a long fairing 1. The step of mounting a short fairing 1 'comprises assembling a first center mount reference 2 with a first reference of 3' end caps for short fairing, and the step of mounting a fairing long 1 comprises assembling said first center mount reference 2 with a second end cap reference 3 for long fairing. FIGS. 48 to 54 describe an embodiment of the invention that is adapted for mounting it on a wiper arm, called an arm-rod, which does not have a U-shaped terminal shape, but in the shape of a substantially straight rod. Figures 48 and 49 show, respectively in assembled position and exploded position, a central mount 2 identical to that of the previous embodiment, in which is inserted an adapter 5 'which is slightly modified with respect to the previous, so that adapt to the mounting on an arm-rod 10 '. Fig. 50 shows the cooperation between the modified adapter 5 'and the arm-rod 10', while Figs. 51 and 52 show respectively the modified adapter 5 'and the arm-rod 10'. The modified adapter 5 'has, as before, substantially a parallelepipedal shape elongate in the longitudinal direction with two lateral wings 52 interconnected by a medial portion which defines a cylindrical housing 51 for the elastic latching of the transverse axis of articulation 25 which passes through the window 21 of the central mount 2. It also comprises, on each lateral flange 52, a longitudinal extension 52a whose object is to serve as a stop to limit the rotation of the adapter in some cases of use, and a lug 53 which abuts against one of the parallel lateral faces 22 of the center of the central mount 2 when the adapter is in a position of maximum rotation. The modified adapter 5 'further includes a transverse plate 54 which connects the lateral wings 52 to their upper level, thus forming a roof for the adapter and defining a longitudinal housing into which the distal end of the arm is inserted. stem 10 '.

This longitudinal housing opens here at its two longitudinal ends. The upper transverse plate 54 extends inwards, with reference to the rotation of the arm, by a longitudinal lug 55, of flat and elongate shape, which comprises near its end opposite the plate 54, a retaining finger 56 which extends vertically downwards, so as to cooperate with a notch 101 made in the arm 10 '. The lower part of the transverse plate 54 and the longitudinal tab 55 is such that it provides a space in which can be slid and come to be housed the rod arm 10 '. Due to its elongation, the longitudinal lug has a certain flexibility and is attached to the plate 54 by an elastic connection which leads naturally downward, which tends to maintain its contact against the arm-rod over its entire length . The tab 55 extends substantially in a plane P10 passing through an upper end of the adapter. As for the arm-rod 10 ', visible in Figure 52, it has, without this being imperative, a lowering at its end portion to form a second flat portion which is located at a lower height than the first part. This shape is intended to make it geometrically closer to the adapter used. It comprises a notch 101 which is located at a distance from its end such that the retaining finger 56 carried by the longitudinal lug 55 is longitudinally at its level when the arm-rod is inserted into the adapter. FIGS. 53 and 54 show, respectively in plan view and from below, and in longitudinal section, the arm-rod 10 'in its housing below the longitudinal tab 55 and the transverse plate 54. The retaining finger 56 is entered in the notch 101 of the arm-rod, which ensures the attachment of the rod-arm 10 'and the adapter 5', this configuration being reversible due to the longitudinal flexibility of the tab 55. Referring now to FIGS. 55 to 60 will describe another embodiment, in the configuration of the assembly on a conventional arm, with a U-shaped end portion. This mode can equally well be implemented on an arm-rod, provided that the adapter set up either, as in the previous embodiment, adapted to this type of arm. In this mode, the blade is shifted laterally relative to the arm 10 and held in position by a connecting member configured for this purpose. On the other hand, the central frame 2 and the adapter 5 or 5 'are identical to those of the modes described above. Figures 55 and 56 show, respectively in front view and in rear view, a wiper blade mounted on a U-shaped arm, in the assembled position, while Figure 57 shows the wiper in disassembled position.

The arm 10 has a conventional shape terminating in a U in which is inserted the adapter 5 previously described, as shown in Figure 60. The adapter 5 comprises in particular a cylindrical housing 51 in which can be clipped an axis of articulation such as that extending between the two parallel lateral faces 22 of a central mount 2. Between the adapter 5 and the central mount 2 extends an intermediate piece, or connecting member 11, which receives the 5 adapter snap on a second hinge axis 25 'and which is itself clipped on the transverse axis 25 of the central mount. In this configuration the connection member 11 is fixed relative to the blade and the rotation of the arm, and the adapter 5, is performed around the second axis of articulation 25 '. The connecting member 11 is described in more detail with reference to FIGS. 58 and 59. This member has the shape of two bodies extending longitudinally and which are placed symmetrically with each other with respect to a direction longitudinal. They are attached to each other by means of a longitudinal central wall 111 oriented longitudinally, one being positioned at the top of this central wall, the other being positioned at the bottom. The first body 11a appears open on the top while the second body 11b appears closed in top view because it opens downwards. The second body 11b forms means for connecting the member 11 to the frame, that is to say that it cooperates with the frame to secure the body to the blade. In the example shown, the second body comprises fixing means configured to cooperate by interlocking or snap elastic with at least one axis of the frame 2, as will be described in the following. A first median transverse plane Pl1 to the first body 11a, passing through the axis 25 ', is parallel and at a distance from a second median plane P12, parallel to the plane P11, and passing through the second body 11b.

The first body is transversely U-shaped, being formed by three flat surfaces perpendicular to each other, which extend in the longitudinal direction. From the central wall 111 extends a floor wall 112 whose width is approximately equal, by a value less than that of the window 21 of the central mount 2. And this floor wall extends upwardly a third wall 113 which substantially reproduces the shape of the central wall 111, being the mirror with respect to the median plane of the floor wall. It will also be seen in the figure the second hinge axis 25 'which extends transversely between the first and third walls 111 and 113, and which provides the support function of the adapter 5 which the axis of articulation 25 in the first or the previous embodiments. Finally, the three walls of the first body 11a extend longitudinally and vertically so as to substantially reproduce the shape of the window 21 of the central mount 2, so that the adapter 5 can be attached to it as it did in the window of the central mount. The second body 11b has the function of securing the connection member 11 with the central mount 2, while ensuring a closure of the window 21 of the central frame to improve the aerodynamics of the assembly. For this, it comprises a ceiling wall forming a cowling 114 which extends from the upper edge of the central wall 111, in the opposite direction to the first body 11a. This cowling 114 extends the upper surface of the central mount 2 and provides both aesthetic and aerodynamic continuity. This cowling 114 carries a rib 115 which extends longitudinally in its middle, along its length and which extends downwards until it comes to a height corresponding to that of the transverse hinge axis 25. Au the middle of its length, this rib 115 is cut by a cylindrical housing 51 'intended to receive by snapping the hinge axis 25 of the central frame 2 and to hold in place the connection member 11 in the window 21 of the central mount 2.

At each of its longitudinal ends, the cowling 114 comprises another cylindrical housing 51 "which is intended to receive by interlocking or snap elastically an axis 27 of the central mount 2. In a variant not shown, the connection member 11 could be formed in one piece with the central mount 2. Referring to FIGS. 61 to 65, another embodiment of the invention will now be described.This mode is intended to adapt a ducted flat mop to an adapter already existing, which is suitable for a flat broom.

The invention consists in modifying the central mount with respect to those previously described and inserting a second connection member between this modified central mount and the existing adapter, as can be seen in FIG. 61. Referring to FIG. 62 , we see a central mount 2 ', similar to that of the previous modes, except that it has no transverse axis of articulation. The parallel side walls 2a, 2b are here leveled to leave space for the existing adapters 50, 50 ', 50 ", the upper part of the central part of the central frame 2' thus forming a horizontal plane 22 'in which is The outer contour, at the bottom, of the second connecting member 200 reproduces the shape of the window 21 ', so that after implantation of the second connection member, the window is completely closed. , this member 200 comprises in the lower part a cowling 222 'defining a horizontal plane which is positioned in the extension of the horizontal plane 22', Figure 63 shows the central part of the central mount 2 ', with its horizontal plane 22' in which the window 21 'is hollowed out, this window 21', of rectangular shape, without this form being imperative, does not have an undercut shape in the vertical direction and is inserted into the central frame 2 ' rmant a cavity, as in the case of the central frames of the previous embodiments, to reach the upper face of the longitudinal plate which extends above the hooks 23 for supporting the holding member 7. A l ' inside this cavity, the parallel lateral faces 22 comprise vertical ribs 211 'which serve, between them, to guide corresponding ribs 211 positioned on the second connection member 200. At the longitudinal ends of the window 21', there are hooking means of the second connecting member 200. For this, there are on one side two female interlocking stops 212 'which project towards the inside of the window, starting from each of the lateral faces 22, 10 to forming a retaining in the vertical direction to male means 212 positioned on the second connecting member 200. These male means 212 have the form of longitudinal extensions which are positioned laterally of way to meet the females interlocking stops 212 'and can be housed below them. These female stops 212 'and these male means 212 have cylindrical shapes, with generatrices oriented laterally, so that they allow a rotation of the second connection member 200 in a vertical plane for its positioning on the window 21'. At the other end of the window 21 'there are two female latching means 213', which extend, also projecting towards the inside of the window, starting from each of the lateral faces 22. These means latching females 213 'have, in negative, a cylindrical shape with a circular base, which is open at the top and whose upper edges can move away from each other in an elastic manner. Meanwhile, the second connecting member 200 comprises at the opposite end of its interlocking means, two male latching means 213 whose shape is the mirror female means 213 'latching the window 21'. The introduction of the second connection member 200 in the window 21 'is thus carried out in the following manner: the operator positions the second connection member 200 in the window 21' by positioning it at an angle and passing the male interlocking means 212 under the female interlocking means 212 ', then it causes the second connection member 200 to execute a rotation which brings it substantially horizontally, which causes the male detent means 213 in front of the female means latching 213 'and simultaneously the ribs 211 of the second connecting member 200 between those 211' of the window 21 '. Then a vertical pressure engages the male latching means 213 in the female latching means 213 ', which ensures the joining of the two parts. Referring to Figures 64 and 65, we see the second connecting member 200 which essentially comprises a central plate 222, the upper face 222 'forms the desired continuity for the cowling with the horizontal plane 22' of the central frame. From this central plate extend downwards, in the center, lateral guide means 214 which carry the guide ribs 211 and at the longitudinal ends, on the one hand the male interlocking means 212 and on the other hand, the male locking means 213. From the central plate extends upwardly a structure 230 for supporting an adapter. This structure is substantially in the form of a parallelepiped extending longitudinally in the center of the plate over the entire length thereof. It carries at its upper part two aligned transverse journals 235 which form an axis having the same characteristics as the transverse axis of articulation 25 of the windows 21 of the central frames of the preceding modes, and which can thus be integrated into the cylindrical housing 51. Existing adapters 50, 50 ', 50 ", preferably these journals 235 comprise, at their upper part, a chamfered face 235a to facilitate their insertion into said cylindrical housing.
