Description

WINDSCREEN WIPER DEVICE AND CONNECTING 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 at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein said oscillating arm can be pivotally connected to said connecting device about a pivot axis near a free end thereof, with the interposition of a joint part, wherein said connecting device comprises laterally outwardly extending protrusions engaging into correspondingly shaped recesses of said joint part, said protrusions having a cylindrical shape with a cylindrical axis. Said protrusions may be at least substantially spherical or frusto-conical.
Such a windscreen wiper device is known from European patent publication No. 1 847 425 of the same Applicant. This prior art windscreen wiper device comprises 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 opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of the carrier element are disposed, wherein neighbouring ends of said longitudinal strips are interconnected by a respective connecting piece, 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 near one end, with the interposition of a joint part, wherein said joint part is detachably connected to said connecting device by engaging protrusions of said connecting device, at the location of said pivot axis, in recesses provided in said joint part, and wherein said protrusions are provided with coaxial through holes.
A disadvantage of the prior art windscreen wiper device, as for instance known from the above- mentioned European patent document, is that the prior art connecting device is not compatible with certain oscillating arms. In particular, a problem occurs when the connecting end of an oscillating arm is relatively narrow, such that the arm-specific joint part, near its top portion (in vicinity of the connecting end of the oscillating arm), is locally too narrow to engage the known connecting device, and in particular to engage the protrusions thereof. Namely, the joint part must be made narrower in those areas where the connecting end of the oscillating arm is particularly narrow in order to allow the connecting end to engage with the joint part. Accordingly, the narrowed top portion of the joint part protrudes upward from the connecting device, as that particular top portion is too narrow to engage the connecting device. This results in the oscillating arm being raised upwards from the connecting device in comparison to an oscillating arm with a more traditional (i.e. broader) connecting end. Such raised position results in increased wear and stresses in the windscreen wiper device and/or the oscillating arm, which is detrimental to the performance and longevity of the device and/or arm. Consequently, the connecting device for an oscillating arm needs to be adjusted for each specific oscillating arm, and specifically for such oscillating arms with relatively narrow connecting ends.
The object of the present invention is to overcome drawbacks of the prior art as indicated above and to provide an improved windscreen wiper device, in particular to provide a more universal windscreen wiper device that is compatible with the majority of windscreen wiper arms, and more in particular to provide a windscreen wiper device comprising a connecting device to be universally used for both wide and narrow connecting ends of oscillating arms.
In order to accomplish that objective, amongst other objectives, a windscreen wiper device of the type referred to in the introduction, is characterized according to the invention in that a circular sector of at least one of said protrusions is removed over at least part of a length, along said cylindrical axis, from a free end of said at least one protrusion.
By having a circular sector of a protrusion removed from a free end of the protrusion over at least part of the length of the protrusion, the connecting device is made narrower along the height thereof where connecting ends of oscillating arms may vary in width. Thereby, various armspecific joint parts can be clipped onto the connecting device, including joint parts made locally narrower (e.g. having a narrow top portion) due to a particularly narrow connecting end of an oscillating arm, without the arm being raised upwards from the connecting device, which is the case for the prior art connecting device, as described above. In other words, the connecting device is locally narrowed by (at least partially) removing a circular sector of the protrusion, such that a narrow top portion of a joint part may engage the connecting device where it is locally narrowed. Since only a sector instead of all of the protrusion is removed over at least part of the length of the protrusion, the protrusion can still engage with recesses of wider joint parts, i.e. for wider connecting ends of oscillating arms. The protrusion thus retains the functionality of the protrusion of the aforementioned prior art, while enabling in addition the connecting device to be used in windscreen wiper devices with an oscillating arm having a particularly narrow connecting end, without causing the aforementioned increased wear and stress due to a raised position of the oscillating arm with the narrow connecting end, as is the case for the aforementioned prior art windscreen wiper device. The essence of the present invention is that said connecting device is a universal connection part for each type of interconnection between the wiper blade and the oscillating arm. A different type of said joint part to be connected to said connecting device may be used for each different type of interconnection between the wiper blade and the oscillating arm. The advantage achieved by the invention is that a unit consisting of said wiper blade and said connecting device connected to said longitudinal strips can be manufactured for each and every type of interconnection between said wiper blade and said oscillating arm, while only a relatively cheap and easy to manufacture joint part to be connected to said connecting device has to correspond with a specific type of interconnection between said wiper blade and said oscillating arm. Thus, a universal connection between the wiper blade and the oscillating arm is obtained, so that car drivers are given the possibility to buy also non-original cheap wiper blades fitting the original oscillating arms on their cars. Said joint part may be connected to said connecting device through a snapping/clipping operation. Said connecting device acts as a base part, wherein the connecting device is preferably fixedly connected to the longitudinal strips through a welding, brazing ("soldering"), gluing or clamping operation.
The circular sector of at least one of said protrusions may be removed over the full length or part of the length of the protrusion. The protrusion then comprises an outer surface at a free end, the outer surface having a shape of a substantially circular or annular sector, wherein the cross-section of the protrusion perpendicular to the length of the protrusion is substantially identical in shape to the outer surface. The cross-section may be substantially uniform along the length of the protrusion.
It is noted that the term “circular sector” may also be replaced by “circular segment”, and vice versa, without departing from the scope of the invention.
Accordingly, a windscreen wiper device is provided, wherein the connecting device is compatible with most joint parts for oscillating arms such that only the joint part is arm-specific and the connecting device can be made universal, in particular to be universally used for connecting ends of oscillating arms that vary in width. Consequently, the cost of producing connecting devices for oscillating arms can be reduced because the connecting device having a unique shape can be universally used.
In an embodiment of the windscreen wiper device, an outer perimeter of said circular sector faces said oscillating arm. By having an outer perimeter facing the oscillating arm, the circular sector of the protrusion is removed at a side of the protrusion facing away from the wiper blade and at a location where a joint part for an oscillating arm with a narrow connecting end is narrow (i.e. the top portion of the joint part where the oscillating arm connects with the joint part). The circular sector of the protrusion is removed in this location for the purpose of being compatible with the joint part that is narrow at said location, i.e. a joint part having a narrow top portion.
In a further embodiment, said cylindrical axis is coaxial with said pivot axis. By having a cylindrical axis that is coaxial with the pivot axis, said protrusion can define the pivot axis when pivotally connecting the connecting device and an oscillating arm with the interposition of a joint part. Regardless of the joint part or oscillating arm used in the pivot connection, the pivot axis remains the same, being defined by the cylindrical axis of the protrusion of the connecting device.
In a further embodiment, said protrusions are provided with coaxial through holes. By comprising protrusions provided with coaxial through holes, said connecting device can be pivotally connected to said oscillating arm near its free end about a pivot axis of a transverse pivot pin provided on said oscillating arm, said pivot pin being inserted into said coaxial through holes of said protrusions of said connecting device. Particularly, said joint part has an at least substantially U-shaped crosssection at the location of its connection to said connecting device, wherein said joint part in each leg of said U-shaped cross-section is provided with a recess provided coaxially with said pivot axis, said recesses being coaxial, and wherein said pivot pin is inserted into said coaxial recesses and into said coaxial through holes of said protrusions of said connecting device. Accordingly, the pivot pin can fix the relative positions of the oscillating arm, the joint part, and the connecting device.
Legs of the U-shaped cross-section may be orientated towards a windscreen to be wiped and a base of the U-shaped cross-section may be orientated parallel to a windscreen to be wiped. Between the legs of the U-shaped cross-section and protruding in a direction towards the wiper blade may be said pivot pin whose pivot axis may extend in a direction of the oscillating movement of the oscillating arm. The diameter of the pivot pin may be adapted to the diameter of the through holes in said connecting device and to the diameter of the recesses of said joint part, said through holes and said recesses being coaxial. Alternatively or additionally, the diameter of the through holes may be adapted to the average and/or standard diameter of the pivot pin. In order to secure or retain the connecting device (and thus the wiper blade) onto the oscillating arm said oscillating arm may be provided with an extension comprising said pivot pin and an L-shaped shoulder which projects out in the direction of said pivot pin and across said wiper blade and at the free end of which is disposed a leg facing the windscreen. In a further embodiment, said circular sector comprises an area of at least a quarter of a base of said at least one protrusion. The base of a cylindrical protrusion is a circular or substantially ringshaped base and is provided on the connecting device. By removing a part of a length of at least one of said protrusions from an area of at least a quarter around the free end of said protrusion, a relatively narrow connecting end of an oscillating arm can be connected, at a suitable low position in order to mitigate wear and stresses, to the connecting device with the interposition of an armspecific joint part.
Preferably, said circular sector comprises an area of substantially half of a base of said at least one protrusion. If a part of a length of at least one of said protrusions is removed from an area all around the free end of said protrusion, i.e. when the circular sector comprises an area equal to said base of said at least one protrusion, the connecting device would not retain the possibility to be universally used, because the connecting device would lose compatibility with wider connecting ends of oscillating arms. By removing a part of a length of at least one of said protrusions from an area of substantially half around the free end of said protrusion, connecting ends from relatively narrow to relatively wide can be connected to the connecting device with the interposition of an arm-specific joint part. The circular sector comprising an area of substantially half around the free end, i.e. half of said base of said protrusion, enables an optimal shape of the protrusion for the connecting device to be universally used. In particular, the circular sector comprising an area of substantially half of said base enables a suitable fit for joint parts of both narrow and wider connecting ends of oscillating arms.
In a further embodiment, said connecting device is substantially symmetric with a plane of symmetry perpendicular to the pivot axis.
In a further embodiment, said connecting device is substantially symmetric with a plane of symmetry perpendicular to the longitudinal axis of said wiper blade, and preferably intersecting the pivot axis.
Symmetry enables the connecting device to be more universally used. A symmetric connecting device can for example be used in windscreen wiper devices for both left hand drive and right hand drive vehicles. Furthermore, using a symmetric connecting device reduces the number of unique components in for example a butterfly windscreen wiper system. During assembly of the windscreen wiper device, the connecting device cannot be wrongly orientated with respect to an oscillating arm when connecting the oscillating arm to the connecting device due to its symmetry. The symmetry of the connecting device thereby simplifies the use of the connecting device and saves time. In particular, a windscreen wiper device with a connecting device being substantially symmetric with a plane of symmetry perpendicular to the pivot axis, and/or a plane of symmetry being substantially symmetric with a plane of symmetry perpendicular to the longitudinal axis of said wiper blade (and preferably intersecting the pivot axis), enables it to be used for both left hand drive cars and right hand drive cars, as the windscreen wiper device can be inverted without losing the ability to connect the oscillating arm to the connecting device with interposition of the joint part.
The present invention also relates to a connecting device as a single unit, as defined in any of the foregoing embodiments.
Another aspect of the present invention relates to a connecting device arranged for pivotally interconnecting a windscreen wiper device of the flat blade type and an oscillating arm about a pivot axis near a free end thereof, with the interposition of a joint part, wherein said connecting device comprises laterally outwardly extending protrusions arranged to engage into correspondingly shaped recesses of said joint part, said protrusions having a cylindrical shape with a cylindrical axis, characterized in that a circular sector of at least one of said protrusions is removed over at least part of a length, along said cylindrical axis, from a free end of said at least one protrusion. The essence of the present invention is that said connecting device is a universal connection part for each type of interconnection between the wiper blade and the oscillating arm.
By having a circular sector of a protrusion removed from a free end of the protrusion over at least part of the length of the protrusion, the connecting device is made narrower along the height thereof where connecting ends of oscillating arms may vary in width. Thereby, various armspecific joint parts can be clipped onto the connecting device, including joint parts made locally narrower (e.g. having a narrow top portion) due to a particularly narrow connecting end of an oscillating arm, without the arm being raised upwards from the connecting device, which is the case for the prior art connecting device, as described above. Since only a sector instead of all of the protrusion is removed over at least part of the length of the protrusion, the protrusion can still engage with recesses of wider joint parts, i.e. for wider connecting ends of oscillating arms. The protrusion thus retains the functionality of the protrusion of the aforementioned prior art, while enabling in addition the connecting device to be used in windscreen wiper devices with an oscillating arm having a particularly narrow connecting end, without causing the aforementioned increased wear and stress due to a raised position of the oscillating arm with the narrow connecting end, as is the case for the aforementioned prior art windscreen wiper device. Accordingly, a connecting device is provided that is compatible with most joint parts for oscillating arms such that only the joint part is arm-specific and the connecting device can be made universal, in particular to be universally used for connecting ends of oscillating arms that vary in width. Consequently, the cost of producing connecting devices for oscillating arms can be reduced because the connecting device having a unique shape can be universally used.
In an embodiment of the connecting device, said protrusions are provided with coaxial through holes. By comprising protrusions provided with coaxial through holes, said connecting device can be pivotally connected to an oscillating arm near its free end about a pivot axis of a transverse pivot pin provided on said oscillating arm, said pivot pin being inserted into said coaxial through holes of said protrusions of said connecting device. Accordingly, the pivot pin is able fix the relative positions of the oscillating arm, the joint part, and the connecting device.
In a further embodiment, said circular sector comprises an area of at least a quarter of a base of said at least one protrusion. By removing a part of a length of at least one of said protrusions from an area of at least a quarter around the free end of said protrusion, a relatively narrow connecting end of an oscillating arm can be connected, at a suitable low position in order to mitigate wear and stresses, to the connecting device with the interposition of an arm-specific joint part.
Preferably, said circular sector comprises an area of substantially half of a base of said at least one protrusion. If a part of a length of at least one of said protrusions is removed from an area all around the free end of said protrusion, i.e. when the circular sector comprises an area equal to said base of said at least one protrusion, the connecting device would not retain the possibility to be universally used, because the connecting device would lose compatibility with wider connecting ends of oscillating arms. By removing a part of a length of at least one of said protrusions from an area of substantially half around the free end of said protrusion, connecting ends from relatively narrow to relatively wide can be connected to the connecting device with the interposition of an arm-specific joint part. The circular sector comprising an area of substantially half around the free end, i.e. half of said base of said protrusion, enables an optimal shape of the protrusion for the connecting device to be universally used. In particular, the circular sector comprising an area of substantially half of said base enables a suitable fit for joint parts of both narrow and wider connecting ends of oscillating arms.
In a further embodiment, said connecting device is manufactured from a metal or a plastic. In a further embodiment, the connecting device is manufactured by means of casting, injection moulding, additive manufacturing, or a combination thereof.
The present invention also relates to a windscreen wiper device comprising a connecting device as defined in any of the foregoing embodiments.
Further, disclosed herewith is a connecting device arranged for pivotally interconnecting a windscreen wiper device of the flat blade type and an oscillating arm about a pivot axis near a free end thereof, with the interposition of a joint part, comprises laterally outwardly extending protrusions arranged to engage into correspondingly shaped recesses of said joint part, said protrusions having a cylindrical shape with a cylindrical axis, wherein at least one of said protrusions may comprise a substantially annular base section provided on said connecting device and an extension portion protruding outward from a segment of said base section in a direction parallel to said pivot axis. Said base section may protrude outward from the connecting device in a direction parallel to the pivot axis. Alternatively, said base section comprises an area on a surface of the connecting device, wherein the extension portion protrudes outward from part of said area.
The present invention will hereafter be elucidated with reference to the attached drawings, wherein:
Figure 1 shows a perspective view of a windscreen wiper device;
Figure 2 shows a perspective view of a connecting device and a joint part;
Figure 3 shows a side view of the connecting device as seen along the pivot axis;
Figure 4 shows a top view of the connecting device as seen from a connecting end of an oscillating arm, perpendicular to the pivot axis; and
Figure 5 shows a cross-sectional view of the connecting device as seen along the longitudinal axis of a wiper blade.
Figure 1 shows a preferred variant of a windscreen wiper device 1. Said windscreen wiper device 1 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 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). Neighbouring ends 5 of the strips 4 are interconnected on either side of the windscreen wiper device 1 by means of connecting pieces 6 functioning as clamping members. In this embodiment, the connecting pieces 6 are separate constructional elements, which may be form-locked ("positive locking" or "having a positive fit") or force -locked to the ends 5 of the strips 4. In another preferred embodiment, said connecting pieces 6 are in one piece with the strips 4 made of spring band steel. In the latter case said connecting pieces 6 form transverse bridges for the strips 4, as it were.
The windscreen wiper device 1 is furthermore built up of a connecting device 7 of plastic material for an oscillating arm 8. Alternatively, the connecting device 7 may also be made of metal, such as steel or aluminium. The connecting device 7 is particularly welded, brazed ("soldered"), glued or clamped onto said strips 4. The oscillating arm 8 is pivotally connected to said connecting device 7, with interposition of a joint part 12 (see Figure 2), about a pivot axis near one end. The connecting device 7 is a universal part in the sense that it can be used for each and every type of interconnection between the wiper blade 2 and the oscillating arm 8.
With reference to Figure 2, the connecting device 7 comprises two cylindrical protrusions 9 extending outwards on either side of said connecting device 7, said protrusions 9 having coaxial through holes 10. Alternatively, said protrusions 9 may have a spherical or frusto-conical shape. These protrusions 9 pivotally engage in cylindrical recesses 11 of a plastic joint part 12. In an alternative embodiment, the recesses 11 may have a non-closed shape (i.e. open circumference). Said protrusions 9 act as bearing surfaces at the location of a pivot axis in order to pivot the joint part 12 (and the oscillating arm 8 attached thereto) about said pivot axis near one end of the oscillating arm 8. The protrusions 9 are preferably in one piece with the connecting device 7.
Figure 3 shows a side view of the connecting device 7 comprising a cylindrical protrusion 9 extending outwards on the side of said connecting device 7, the protrusions 9 having coaxial through holes 10. A circular sector 91 of the protrusion is removed, the circular sector 91 comprising an area of substantially half of a circular base of the protrusion 9. An outer perimeter 92 of the circular sector 91 faces the oscillating arm 8 in the windscreen wiper device 1 shown in figure 1. With further reference to Figure 3, the protrusions 9 comprise a substantially annular base section 9a provided on said connecting device 7 and an extension portion 9b protruding outward from a segment of said base section 9a in a direction parallel to said pivot axis. Said base section 9a may protrude outward from the connecting device 7 in a direction parallel to the pivot axis. The extension portion 9b then protrudes further outward from a segment of said base section 9a in the direction parallel to the pivot axis.
In Figure 4 a top view of the connecting device 7 is shown. The connecting device 7 comprises two cylindrical protrusions 9 extending outwards on either side of the connecting device 7. The connecting device 7 is symmetric with a plane of symmetry along section A - A, which coincides with a plane perpendicular to the cylindrical axis of the protrusions 9, wherein the longitudinal axis of the wiper blade 2 is contained in a plane of symmetry perpendicular to section A - A. The connecting device is further symmetric with a plane of symmetry along section B - B of said wiper blade, wherein the cylindrical axis of the protrusions 9 is contained in the plane of symmetry along section A - A, perpendicular to the longitudinal axis of the wiper blade 2.
Figure 5 shows a cross-section of the connection device 7 along section A - A, perpendicular to the longitudinal axis of the wiper blade 2. The connecting device 7 comprises two cylindrical protrusions 9 extending outwards on either side of said connecting device 7, the protrusions 9 having coaxial through holes 10. A circular sector 91 of the protrusions 9 is removed over part of the length L of the protrusions 9, along the cylindrical axis C, from free ends of the protrusions 9, such that the free ends of the protrusions 9 are stepped as seen along the longitudinal axis of the wiper blade 2. The connecting device 7 is symmetric with a plane of symmetry along section B - B, perpendicular to the cylindrical axis C of the protrusions 9. The protrusions 9 comprise a base section 9a provided on said connecting device 7, said base section 9a protruding outward from the connecting device 7 in a direction parallel to the cylindrical axis C, and an extension portion 9b protruding outward from a segment of said base section 9a in a direction parallel to the cylindrical axis C, such that the free ends of the protrusions 9 are stepped.
The invention is not restricted to the variants shown in the drawing, but it also extends to other embodiments that fall within the scope of the appended claims.
