Description
WINDSCREEN WIPER DEVICE The present invention relates to a windscreen wiper device of the "flat blade type" comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an
oscillating arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis, with the interposition of a joint part, wherein said joint part and said connecting device are pivotally connected to each other by mutually cooperating protrusion/recess means.
The present invention also refers to a method for
manufacturing this windscreen device.
Such a windscreen wiper device of the "flat blade type" is generally known. No use therein is made of several yokes pivotally connected to each other, like in traditional wiper blades, but the wiper blade is biased by a carrier element, as a result of which it exhibits a specific curvature.
A disadvantage of the windscreen wiper device according to the prior art is that, when the oscillating arm is pivoted away from the windscreen to be wiped in order to clean the latter, the wiper blade may pivot beyond a certain pivot angle. In that case, when the oscillating arm is pivoted back towards the windscreen to be wiped with a certain
force, the wiper blade may be in such an abnormal position that not only the wiper blade, but also the windscreen to be wiped, is damaged. The object of the invention is to provide an improved windscreen wiper device of the "flat blade type", wherein the disadvantages of the prior art are obviated.
In order to accomplish that objective a windscreen wiper device of the type referred to in the introduction is characterized according to the invention in that said joint part and said connecting device are provided with mutually cooperating protrusion/groove means for limiting a pivot angle of said joint part, and wherein said protrusion/groove means comprise at least one guiding groove and at least one protrusion cooperating with said groove. Particularly, said protrusion is movable in said groove between a first
position corresponding to a wiping position of said wiper blade and a second position corresponding with a mounting position of said wiping blade. More in particular, said joint part is provided with said protrusion and said
connecting device is provided with said groove. As many cars have their own specifications as to a maximum pivot angle of the wiper blade relative to the oscillating arm, in practice only a small change in the shape of the joint part
(particularly the location of the protrusion on the joint part) or in the shape of the connecting device (particularly the length of the groove on the connecting device) is necessary to fit on every type of car.
It is noted that the invention is not restricted to cars, but also refers to rail coaches and other (fast) vehicles.
In a preferred embodiment of a windscreen wiper device in accordance with the invention said joint part extends at least partly between side walls of said connecting device, wherein said joint part is provided with opposite abutting surfaces for abutting against said sidewalls of said
connecting device, wherein said protrusion extends laterally outwardly from one of the abutting surfaces into said groove being provided on one of the sidewalls abutting against that respective abutting surface. In the alternative, said joint part extends at least partly between side walls of said connecting device, wherein said joint part is provided with opposite abutting surfaces for abutting against the side walls of said connecting device, wherein said protrusion extends laterally inwardly from one of the side walls into said groove being provided on one of the abutting surfaces abutting against that respective side wall. Preferably, said joint part is mounted at least partly inside a cavity of said connecting device defined by the side walls thereof. This enables to mount the joint part inside the connecting device by simply sliding said joint part in vertical direction inside said cavity.
When said oscillating arm is slided onto the joint part, the protrusions thereof are forced into position, i.e. into the recesses of the connecting device. Consequently, the joint part cannot be detached from the connecting device in case the oscillating arm is introduced therein. In other words, locking of the oscillating arm on the joint part assures locking of the joint part on the connecting device.
In another preferred embodiment of a windscreen wiper device according to the invention said joint part is detachably connected to said connecting device through a
snapping/clipping operation, wherein said joint part is connected to said connecting device by pivotally engaging cylindrical protrusions, at the location of said pivot axis, extending laterally outwardly on either abutting surfaces in recesses provided on either side walls. In the alternative, said joint part is detachably connected to said connecting device through a snapping/clipping operation, wherein said joint part is connected to said connecting device by
pivotally engaging cylindrical protrusions, at the location of said pivot axis, extending laterally inwardly on either side walls in recesses provided on either abutting surfaces.
In another preferred embodiment of a windscreen wiper device in accordance with the invention said groove extends along a straight line.
In another preferred embodiment of a windscreen wiper device according to the invention said oscillating arm comprises two longitudinal arm sections connected to each other by means of a curved intermediate arm section, wherein said joint part is embraced between said longitudinal and curved intermediate arm sections. Particularly, said joint part has at least two resilient legs, wherein at least one of said legs is provided with a finger engaging into a
correspondingly shaped hole provided in one of said
longitudinal arm sections facing towards the respective leg provided with said finger. More in particular, one of said legs facing towards a windscreen to be wiped is provided with said finger extending downwardly and engaging into said correspondingly shaped hole provided in one of said
longitudinal arm section facing towards the windscreen to be wiped. Said finger may have an inclined upper surface to
facilitate mounting of said oscillating arm onto said joint part .
Finally, the invention also relates to a method for
manufacturing a windscreen wiper device, particularly for automobiles, comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one
longitudinal groove, in which groove a longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm is pivotally connected to said connecting device about a pivot axis, with the interposition of a joint part, wherein said joint part and said connecting device are pivotally connected to each other by mutually cooperating protrusion/recess means, characterized in that said joint part and said connecting device are provided with mutually cooperating protrusion/groove means for limiting a pivot angle of said joint part, and wherein said
protrusion/groove means comprise at least one guiding groove and at least one protrusion cooperating with said groove.
The invention will now be explained in more detail with reference to figures illustrated in a drawing, wherein
Figure 1 is a perspective, schematic view of a
preferred embodiment of a windscreen wiper device according to the invention;
- Figure 2 is a perspective, schematic view of a joint part used in the windscreen wiper device of figure 1, in a bottom view (a) and in a side view (b) ;

Figure 5 schematically shows the way the connecting device, the joint part and the oscillating arm of figures 2, 3 and 4, respectively, are interconnected;
Figure 6 shows in detail the way the joint part of figure 2 is introduced inside the connecting device of figure 4 ;
Figure 7 shows in detail the way the oscillating arm of figure 3 is introduced inside the connecting device of figure 4; and
Figure 8 shows in detail the way a pivot angle of said joint part of figure 2 is limited.
Figure 1 shows a preferred variant of a windscreen wiper device 1 according to the invention. Said windscreen wiper device is built up of an elastomeric wiper blade 2, in the longitudinal sides of which opposing longitudinal grooves 3 are formed, and of longitudinal strips 4 made of spring band steel, which are fitted in said longitudinal grooves 3. Said strips 4 form a flexible carrier element for the rubber wiper blade 2, as it were, which is thus biased in a curved position (the curvature in operative position being that of a windscreen to be wiped) . Neighboring ends 5 of strips 4
are interconnected on either side of the windscreen wiper device 1 by means of connecting pieces 6. The windscreen wiper device 1 is further equipped with a connecting device 7 for an oscillating arm 8, and a spoiler 9.
The oscillating arm 8 and the connecting device 7 are interconnected with the interposition of a joint part 10, as depicted in figure 2. The joint part 10 is made in one piece of plastic material and comprises two resilient legs 11,12 which can be bend towards each other and away from each other. As can be seen in figure 2, the joint part 10 further comprises cylindrical protrusions 13,14, at the location of said pivot axis, extending laterally outwardly for
detachably connecting the joint part 10 to the connecting device 7 through a snapping/clipping operation. The leg 11 of the joint part 10 comprises two laterally outwardly extending protrusions 15 responsible for limiting a pivot angle of the wiper blade 2 relative to the oscillating arm 8, as well as one downwardly extending finger 16 with an inclined upper surface responsible for detachably connecting the joint part 10 to the oscillating arm 8 through a
snapping/clipping operation. This will all be further explained hereunder. In figure 3 the joint part 10 is shown mounted onto the oscillating arm 8. The oscillating arm 8 made in one piece of metal comprises two longitudinal arm sections 17,18 connected to each other by means of a curved intermediate arm section 19, wherein said joint part 10 is embraced between said longitudinal and curved intermediate arm sections 17,18,19. In fact, the longitudinal arm sections 17,18 are positioned in slots 20,21 of the joint part 10. As depicted in figure 3, the finger 16 extending downwardly
from the leg 11 engages into a correspondingly shaped hole 22 provided in the longitudinal arm section 18 facing towards the windscreen to be wiped. Thus, the joint part 10 is snapped/clipped onto the oscillating arm 8. The joint part 10 and the connecting device 7 connected thereto (and thus the wiper blade 2) can be released from the oscillating arm 8 by moving the leg 12 of the joint part 10 away from the leg 11 thereof, that is in downward direction. The connecting device 7 of figure 4 is made in one piece of plastic material and comprises two side walls 23,24 and two end walls 25,26 defining a cavity 27 for introducing the join part 10 therein. When the joint part 10 is entirely mounted inside the cavity 27, opposite abutting surfaces 28,29 of the joint part 10 abut against the side walls 23,24 of the connecting device 8, wherein the cylindrical
protrusions 13,14 extending laterally outwardly on either abutting surfaces 28,29 engage in recesses 30,31 provided on either side walls 23,24 of the connecting device 7. Further, the protrusions 15 extending laterally outwardly from either abutting surfaces 28,29 engage into vertical grooves 32,33 being provided on either side walls 23,24 abutting against the abutting surfaces 28,29. Figure 5 schematically shows the way the connecting device
7, the joint part 10 and the oscillating arm 8 of figures 2, 3 and 4, respectively, are interconnected. The joint part 10 is mounted inside the connecting device by a sliding
vertical movement in the direction of arrow 34, whereas the oscillating arm 8 is first moved in downward direction in the cavity 27 and then slided back in the direction of arrow 35 to lock the protrusion 16 of the joint part 10 inside the correspondingly shaped hole 22 in the oscillating arm 8.
Figure 6 shows in detail the way the joint part of figure 2 is introduced inside the connecting device of figure 4. By sliding the joint part 10 in vertical direction inside the cavity 27 of the connecting device 6, the protrusions 15 extending laterally outwardly from the joint part 10 engage into the vertical grooves 32,33 on both side walls 23,24 of the connecting device 7. Simultaneously, the cylindrical protrusions 13,14 extending laterally outwardly from the joint part 10 engage into the recesses 30,31 on both side walls 23,24 of the connecting device 7. A shoulder 36 of the joint part 10 extending laterally outwardly from the leg 11 thereof (see figures 2 and 3) cooperates with a stop surface 37 in the side wall 24 of the connecting device 7 in order to limit the movement of the joint part 10 inside the connection device 7 in a direction facing towards the windscreen to be wiped. As already indicated, the movement of the joint part 10 inside the connection device 7 in a direction facing away from the windscreen to be wiped is limited by the protrusions 15 in cooperation with the grooves 32,33.
As shown in figure 7 by arrow 38, the oscillating arm 8 of figure 3 is introduced inside the connecting device 7 of figure 4, wherein the joint part 10 is already mounted in accordance with what is shown in figure 6, by moving it first in downward direction in the cavity 27 of the
connecting device 7 and then sliding it back in. At the end of the latter movement the protrusion 16 of the joint part 10 snaps inside the correspondingly shaped hole 22 in the oscillating arm 8. When said oscillating arm 8 is mounted onto the joint part 10, the protrusions 13, 14 thereof are "automatically" forced into position, that is into the
recesses 30, 31 of the connecting device 7. Consequently, the joint part 10 cannot be detached from the connecting device 7, when the oscillating arm 8 is introduced therein. Figure 8 shows in detail the way a pivot angle of the joint part 10 of figure 2 is limited.
In a direction facing towards the windscreen to be wiped the movement of the joint part 10 inside the connection device 7 is limited by cooperation of the shoulder 36 extending laterally outwardly from the leg 11 thereof and the stop surface 37 in the side wall 24 of the connecting device 7. In a direction facing away from the windscreen to be wiped the movement of the joint part 10 inside the connection device 7 is limited by the protrusions 15 extending
laterally outwardly from the joint part lOin cooperation with the grooves 32,33 inside the side walls 23,24 of the connecting device 7.
Although not depicted in the figures, it will be clear for a person skilled in the art that the oscillating wiper arm 8 is connected to a mounting head fixed for rotation to a shaft driven by a small motor. In use, the shaft rotates alternately in a clockwise and in a counter-clockwise sense carrying the mounting head into rotation also, which in turn draws the oscillating wiper arm 8 into rotation and by means of the connecting device 7 moves the wiper blade 2.
The present invention is not limited to the embodiment shown, but extends also to other embodiments falling within the scope of the appended claims.
