Description
SPECIFICATION
Windscreen wiper installation
This invention concerns a wiper blade for windscreen cleaning installations on vehicles, especially on motor vehicles.
As is known the air stream striking the wiper blade laterally produces a lifting force at the supporting structure and at the wiper element which is effective in a direction away from the pane to be cleaned.
Thus the contact pressure of the wiper element on the pane is diminished, so that the wiping pattern deteriorates and the wiper blade may be lifted at high vehicle speeds. This is not admissible on grounds of security.
Many efforts to solve this problem have become known, although no entirely satisfactory solutions have been found. The practice shows that spoilers closely arranged to the windscreen are most effective against the attacking air stream. Such an arrangement is for example known from the German sopecification OS 2346100. However the embodiments known from this specification include disadvantages. Thus the spoilers to be attached to the yoke or to be inserted in it can only be secured thereon in a relatively complicated way and, moreover, the connecting points are subject to considerable wear and do not look very nice.The other embodiment known from this specification including a spoiler formed out of the wiper element might not be stable enough to act against the air stream in all cases, bcause of the rubber-elastic materials normally used for the production of wiper elements. Moreover, as far as technology is concerned, the production of such a wiper element might be very difficult and therefore expensive.
It is an object of the invention to create a wiper blade whose spoiler can be connected with the wiper element in a simple way and at any time ensures a reliable contact between the wiper element and the windscreen.
According to the invention there is provided a wiper blade for windscreen cleaning installations on vehicles, especially on motor vehicles, comprising a supporting structure including at least one yoke element for holding a wiper element of rubberelastic material, which wiper element is flexibly stiffened by a flexible strip extending over almost its entire length, whereby the wiper element is provided with at least one spoiler, and wherein the spoiler is formed on or attached on the flexible strip.
With such a spoiler arranged the lifting force created by the air stream is on the one hand deflected from the wiper blade and on the other hand transmitted to the wiper element via the flexible strip as a contact force. Because also the contact pressure created by the wiper arm is transmitted to the wiper element via the supporting structure, it is hardly possible any more lift the wiper element from the pane unintendedly.
When the spoiler and the flexible strip are moulded plastics parts a simple and economical production is possible, in particular, when the two parts form one piece. In this case the flexible strip simultaneously serves to stiffen the wiper blade flexibly and is used as a spoiler.
It is easily possible to retrofit a wiper blade by squeezing a spoiler against its flexible strip or clipping it on this flexible strip.
If the flexible strip with its back laps over the head of the wiper element and engages thereon by means of downwardly directed elongations, it is possible to form the back of the flexible strip itself as a spoiler and/or form a spoiler on it or attach it onto it. In this case the flexible strip in addition serves to strengthen the head of the wiper element.
The spoiler can be fored onto one of the downwardly directed elongations of the flexible strip. The elongations can either uninterruptedly extend over the entire length of the flexible strip or can be formed as individual claws. On grounds of stability the first solution is to be preferred.
If at least one projection extending along its back is formed on the flexible strip, the spoiler can be attached to this projection.
It is particularly advantageous, when projections are formed on the flexible strip to both sides, which projections extend over the entire length of the back of the flexible strip. On the one hand then spoilers can be provided on both sides of the wiper element, and on the other hand the wiper element can be secured to the supporting structure by means of these projections. If desired the projections can be provided with locking points which serve as stops for the supporting structure.
When the spoiler extends over the entire length of the wiper element, this results in a uniform contact pressure between wiper blade and pane when the laterally striking air stream is well used.
As far as supporting structures are concerned which consist of an interlocking yoke system with several clawed yokes carrying the wiper element and one main yoke articulated to the clawed yokes, the contact pressure transmitted to the wiper element transmitted from the wiper arm via such a supporting structure is not the same in all places. As is known the pressure between the working points of the clawed yokes is slightly lower than at the working points of the clawed yokes on the wiper element. It can therefore be reasonable to arrange spoilers in these places of the wiper element.
When the spoiler is formed on one of the downwardly directed elongations of the flexible strip and the wiper element is secured to the supporting structure via the lateral projections of the back of the flexible strip it is reasonable to curve in upward direction the area below the lateral projection of the spoiler and to make the spoiler surface plane. Then the supporting structure can be positioned in one plane with the spoiler surface on the side exposed to the wind, so that the air stream can especially well be carried away from the wiper blade. Due to the curvature of the spoiler directed towards the back of the flexible strip the spacing between the supporting structure and the spoiler is so small, so that a swirling of the air in the gap between supporting structure and spoiler is prevented to a far-reaching extent.
A good effect can also be achieved by a spoiler which is equipped with a second wiper element arranged in parallel to a first wiper element. By this measure the first wiper element can be completely protected against the air stream appearing.
It is of a particular advantage, when the second wiper element is lower than the first wiper element.
In this case the second wiper element can be connected with the first wiper element through a spoiler, which is formed in one piece on the flexible strip of the first wiper element and laps over the head of the second wiper element. In this case the flexible strip could be designated as a double or twin flexible strip, because it is connected with two wiper elements.
However it would be also conceivable to secure such a spoiler to the flexible strip of the first wiper element by means of holding clips or similar fastening means and is formed in one piece only with the second wiper element.
If the spoiler includes moreover a surface ascending relative to the pane to be wiped, which surface is arranged above the head of the second wiper element, it is prevented to a far-reaching extent that the wiper blade can be lifted unintendedly by the air stream, not even at high vehicle speed.
The drawings show diagrammatic sections not true to scale of embodiments according to the invention, in which
Figure 1 is a wiper element including a spoiler which is formed on a flexible strip,
Figure 2 is a wiper element whose spoiler is formed on both sides of a flexible strip,
Figure 3 is a wiper element including a flexible strip whose back is formed as a spoiler,
Figure 4 is a wiper element whose spoiler is clipped onto a flexible strip,
Figure 5 is a wiper element including a double or twin flexible strip and
Figure 6 is a further wiper element including a flexible strip, whose back is formed as a spoiler.
All rubber wiper elements 10 shown in Figures 1 to 5 include a head 11 having a rectangular crosssection which head is equipped with a longitudinal groove 12, 13 each at approximately half of its height. To the head 11 follows a tilting web 14, through which a wiper lip 15 is connected with the head 11. It is provided that, during a wiper operation, the wiper element 10 touches a pane to be cleaned with the downwardly directed tip of the wiper lip 15.
The recesses 16, 17 which are necessaryforthe tilting web 14 and the longitudinal grooves 12, 13 have a rectangular cross-section. On the whole it can be seen from Figures 1 to 5 that the wiper element is developed in a manner known in itself, so that further explanations are not necessary.
To maintain contact pressure in use the wiper elements are equipped with a spoiler 20, which is formed on or attached to a flexible strip 30. Thereby each flexible strip 30 shown in Figures 1 to 6 consists of a moulded plastics part which with its back 31 laps overthe head 11 of a rubberwiperelement 10. On both sides of the back 31 of the flexible strip 30 an elongation 32, 33 is formed, which is downwardly directed, bent towards the wiper element 10 and which engages into the longitudinal groove 12 and 13 respectively which is arranged in the head 11 of the wiper element 10. It is provided that the flexible strip and the elongations extend over the entire length of the rubber wiper element on grounds of stability.
The spoiler 20 shown in Figures 1 to 3 and in
Figures 5 to 6 forms an integral part with the flexible strip 30 so that the flexible strip 30 simultaneously strengthens the wiper element 10 and prevents that it is lifted from the pane.
The spoiler 20 shown in Figures 1 includes a surface 21 which ascends relative to a pane to be cleaned not shown in the drawing, which surface is formed on the downwardly directed elongation 32 of the flexible strip 30. The back 31 of the flexible strip 30 is laterally elongated beyond the head 11 of the wiper element 10 and forms two projections 34,35, on which the wiper element 10 may be secured to a supporting structure of which a yoke element is shown here, which embraces the projections 34,35 by means of its claw-shaped ends 41,42.
The spoiler 20 is thereby substantially formed as a shovel, which below the lateral projection 34 is curved in upward direction towards this projection 34. The plane part of the shovel forms the actual wind deflector surface 21, which extends approximately as far as to half of the height of the wiper lip 15. The surface 21 is approximately positioned in a plane with the outer surface 41a of the claw 41, which during the wiper operation is exposed to the air stream, so that the laterally flowing air stream can be well deflected via the surface 21 and the supporting structure.
The wiper element 10 shown in Figure 2 has a spoiler 20 which extends on both sides of its head 11. Thereby the spoiler 20 includes a surface 21 formed on the back 31 of the flexible strip and slightly curved forwards in the direction of the wiper element 10, which surface is to be exposed to the laterally flowing air stream. This air stream exerts a pressure on the spoiler 20 and thus on the flexible strip 30, which transmits the pressure to the wiper element 10 and thus prevents that it is lifted from the pane to be cleaned. As is known part of the air streams beyond the head 11 of the wiper element 10 towards the pane and is swirled there, which could also result in an undesired lifting. In the wiper element 10 shown here this is cured by an upwardly directed wind deflector surface 22 which, in the mounted condition of the wiper blade, points away from the pane. By this measure an air stream appearing behind the wiper element 10 can be deflected.
However it would also be conceivable to direct the elongation 22 in the downward direction perpendicularly or at an acute angle and to conduct it as far as possible down the pane, so that the air stream appearing behind the wiper blade is carried away from the wiper element 10.
A similar wiper element to that of Figure 2 is shown in Figure 3. Here in addition the back 31 of the flexible strip 30 is developed as a spoiler 20, so that an especially large wind deflector surface 21 is exposed to the air stream. The small amount of air streaming behind the wiper element is also in this case deflected by an upwardly directed wind deflector surface 22. Because the back 31 of the resilient strip is developed as a hollow member with about triangular cross-section, there is a hollow space between the surfaces 21 and 22 which possibly migh be disadvantageous.
This disadvantage is avoided in a wiper element according to Figure 6 in that the head 11 includes an inclined surface 18 which closely rests against the back 31 of a flexible strip 30 and is lapped over by it.
The back 31 of the flexible strip is on both sides elongated beyond the inclined surface 18 of the head 11 of the wiper element 10 and forms the wind deflector surface 21. In this case the somewhat smaller, downwardly directed elongation 23 is to be exposed to the air stream. The pressure exerted by the air stream on the back 31 of the flexible strip 30 can especially effectively be transmitted to the head 11 of the wiper element due to the close fit of the parts, so that the tendency of their being lifted is dimished. The air behind the wiper element 10 can be carried away via the elongation 22.
In a comparison to the previously shown rubber wiper elements a further difference of the wiper element according to Figure 6 is to be seen in the fact that the flexible strip 30 engages in the recesses 16 and 17 which are necessary to form the tilting web 15. It is provided that the wiper element 10 is to be secured to a supporting structure at this recesses 16, 17. For this purpose a supporting structure including clawed yokes would be suitable, which preferably extend through recesses longitudinally arranged along the spoiler and which can embrace the head of the wiper element. The longitudinal grooves in the head of the wiper element, which in other cases serve to secure the wiper element, are saved in this version, so that the wiper element can be produced by a press tool of a simpler design.On principle the flexible strips of the previously described figures of the drawing can be secured on the head of the wiper element as described here, however the increased danger of breaking has to be taken into consideration when the tilting web is designed.
The flexible strip 30 including a spoiler 20 shown in Figure 5 is also produced as an integrally moulded plastics part, whereby the spoiler 20 is a solid part.
Similar as in the version of Figure 1 the spoiler 20 is formed on a downwardly directed elongation of the flexible strip, however laps over the head 11 a of a lower wiper element 1 Oa, which otherwise is constructed identically to the first wiper element 10. The spoiler 20 is formed on the elongation 32 of the flexible strip 30 via a web 27 and includes two elongations 25 and 26 bent in the direction of the second wiper element 10a, which elongations engage in longitudinal grooves 12a and 13a respectively on the head 1 1a of the wiper element 10. Because the spoiler 20 and the flexible strip 30 form an integral part carrying two wiper elements, this part could be designated as a double or twin flexible strip.
Above the head 11 a of the smaller wiper element 1 0a in this case the spoiler 20 in its cross-section is formed like a double pitch roof with differently large surfaces, whereby its larger surface is arranged away from the first wiper element 10 and forms the wind deflector surface 21. The tip of the roof ends at the level of the back 31 of the flexible strip 30, so that the air streaming over the spoiler 21 is reliably conducted away from the wiper elements 1 0a and 10. The back 31 of the flexible strip 30 has two lateral projections 34, 35 via which the entire device can be secured to a supporting structure.
A particular advantage of this version is that due to the combination with an additional rubber wiper element the spoiler extends as far as to the pane to be cleaned. This is not possible in the other versions which show spoilers completely made from plastics material. Because, as is known, the wiper element and with it the spoiler is tilted during the wiper operation, a spoiler extending as far as to the pane could break it or scratch it. Because the end of the spoiler shown in Figure 5 consists of rubber, disadvantages of this kind are not to be feared. When the end is formed as wiper element or wiper lip the pane can be optimally cleaned.
To the wiper element 10 shown in Figure 4 a spoiler 20 is clipped onto a flexible strip, which spoiler has a cross-section similar to a wing. The back 31 of the flexible strip 30 laps over the head 11 of the wiper element 10 constructed in a usual manner. The projection 34, which extends laterally of the back 31 of the flexible strip, has at the top and at the bottom a recess 36 and 37 respectively, into which the spoiler 20 is clipped by means of detents 28 and 29 respectively formed on it.
Also in this case versions are conceivable in which the end of the lateral projection 34 resting against the spoiler 20 extends both over the entire length of the flexible strip and solely over partial sections. The end of the lateral projection 34 resting against the spoiler 20 could, for example, be also formed as a knob. Likewise it would be possible to rivet or screw the spoiler to the flexible strip. The version shown in
Figure 4 is only a preferred embodiment of a wiper element including a spoiler attached to the flexible strip.
When choosing the plastics material for integrally produced flexible strips with spoiler it has to be taken care that the plastics materials is flexible enough in order to enable an adaption of the rubber wiper element to different pane curvatures, and on the other hand it has enough stiffness not to be deformed by the attacking air stream. For instance polyurethane foam would be a suitable material in the present case of application.
On principle a flexible strip produced from thin metal sheet could also be used, but involves a higher amount of production engineering that a plastics flexible strip which can be injection-moulded.
All embodiments shown in the drawings show a wiper element which includes a spoiler closely arranged to the windscreen and wherein the spoiler is exposed to the air stream which strikes the wiper blade laterally. The spoiler can in all cases be connected with the wiper element in a simple manner. The wiper elements needs only to be put into one of the flexible strips which either has been already equipped with a spoiler or onto which it can be additionally attached.
All embodiments shown illustrate a flexible strip which laps over the head of at least one wiper element. However it would also be possible to insert individual flexible strips in the head of the wiper element, which flexible strips either consist of steel as usual or of plastics material, and to eqiup one of them with a spoiler or form it as a spoiler. In the versions shown due to the uniform load a moment of tilt exerted by the spoiler on the wiper element is effectively overcome. This prevents a premature wear of the wipe lip and ensures a longer service life, which is why this version has to be preferred.
Due to the fact that in all cases conventional rubber wiper elements and supporting structure can be used, the invention provides a stable wiper blade with an advantageous flow pattern, which wiper blade can be produced in a simple manner.
