Description

The invention relates to a wiper, the one Wiper arm, at least one balance beam and a stretcher element for holding and guiding a windshield has the blade and at least in some areas is provided with a transparent training.

Windshield wipers are available in different versions shapes known and are for example in the field of Vehicle technology used. According to the state of the art already known constructions are, for example, in DE-OS 33 47 440, DE-OS 29 09 126, DE-OS 41 11 937 , DE-OS 37 04 914 and DE-OS 33 40 404 described. Can in the field of vehicle technology such wipers, for example, at a  Windscreen, a rear window or in the range of Vehicle lights are used.

The usual wipers consist of a stretcher element, which is usually made of metal. The use of painted steel is widespread. The Wiper blades are typically black Rubber and are held over claws in the area of the tra fixed. It is also known Use plastic wiper support elements the ones that typically have a black design point.

Due to the design of the wipers is at use at least one impairment of the The driver's field of vision cannot be avoided. About it also result from the oscillating movement of the Windshield wiper fatigue effects. With a not ver lowered arrangement of the wipers is also in a state of non-use with impairments of the field of view. Another disadvantage is to be seen in the fact that when using iron or Steel with appropriate weather conditions roster appearances or peel off used paints.

From DE-GM 87 01 962.0 it is already known one Design wipers to be transparent in certain areas. A wiper lip of the wiper is according to this Publication in sections in a transparent Holder embedded. The transparent holder iτ over short balance bars and one the short balance bars main balance beam with a Wiper arm connected. The wiper blade is made of a non-transparent rubber-like material and  the balance beam and the wiper arm are con conventionally made of metal.

An explanation of a conventional wiper made of metal with rubber wiper blade can be found in DE-OS 197 31 683.

The object of the present invention is a shit benwischer of the type mentioned in the introduction structure that be an improved ease of use is provided.

This object is achieved in that both the support element and the wiper arm and the Balance beams are transparent at least in some areas are trained.

Due to the partial or complete transparent off Formation of the wiper ensures that the perceptibility by the user is considerably reduced is set. Impairments of the field of vision as well Fatigue effects could thereby be avoided or increased be reduced at least considerably. More advantageous as the transparent materials are ge chooses to largely avoid mirror effects. In addition, the choice of material is more advantageous in such a way that no optical refractions, distortions Reduction, enlargement or reduction by Lin effects are caused.

Another advantage is that it is nervous Exposure of appropriately sensitive people clear perceptible pendulum movements avoided  the. This applies to both single arm wipers as well also for double wipers.

A further improvement in user comfort can can be achieved in that an at least area as transparent wiper blade is used.

A typical field of application is opened up that use in the field of a motor vehicle is provided.

Both for the construction of the wiper arm as well for the construction of the balance beam (s) is ins special thought of making one to realize a transparent full profile. Such a thing Full profile points compared to conventional use U-profiles have a smaller surface area easier to clean. Because of the geometrically simple The shape of a full profile is relatively few corners and voids where dirt accumulates could mess.

In particular, it is contemplated that an application in Area of a front window of a means of transport is featured see is.

It is also possible that an application in the field a rear window of a means of transport is provided.

Another application is that an application in the area of a lighting device Transportation is provided.  

As a result, he can have an extremely low perceptibility be enough that a colorless transparent version is provided.

In terms of design options, it is also possible that a tinted transparent version featured see is.

To influence material properties is pre suggest that the transparent material with at least another material is combined.

Another embodiment is that minde At least one light element connected to the wiper that is.

Illumination properties can in particular thereby be realized that the lighting element as a light-emitting diode (LED) is formed. Exactly if it is conceivable, film-like as a lighting element Use elements that are transparent or tinted are. The foils can either passively pass light direct or with a corresponding activation Lich generate energy. Another implementation exists in the use of glass fibers or other optical Fibers for light transmission. When light is shining in the transparent wipers can be used to light out coupling reflection particles or reflection areas be used.

To avoid electrical supply lines in the Be But there is also plenty of this in the transparent material thought that arranged outside the support member tes light element shines light into the support element.  

Another advantage of the proposed arrangement is to see that improvements in design under be supported.

A high cleaning effect can be supported be that the support element with at least one trans Parent air guiding element is combined. The improvements te cleaning effect is caused by the fact that an increased pressure of the wiper on the wind protective screen is caused.

Another use variant is that the Luminous element with a control for training egg ner warning light is coupled. The warning light can be in Depends on the respective approval regulations con be structured. Basically, it is conceivable that the Be lighting function only in a parking position or something probably in the park position as well as when carrying out of pendulum movements.

To improve the windshield washer quality is just if you think that the support element is inside Channels for the transmission of windscreen washer fluid having.

With regard to the lighting effects also shows transparent rear window wiper without its own active Lighting elements advantages over the prior art Technology on. Often in the area of the rear window arranged additional brake lights for one user of the rear window wiper during certain movements positions covered. When using a trans Parent rear window wiper is in any position of the Windshield wipers full visibility of the  Brake light ensures that there is the brake light do not shine through the windshield wiper can. A cyclical cover of the brake light beam This avoids lunging.

For the embodiment of FIG. 1 it is seen that a motor vehicle (1) with wipers (2) is permitted. In the illustrated embodiment, wipers ( 2 ) are arranged both in the area of a front window ( 3 ) and in the area of main headlights ( 4 ).

The windshield wipers ( 2 ) are formed at least in regions from a transparent material. As materials for this purpose, for example, transparent plastics, mineral substances or glass can be used. In particular, it is contemplated to make those areas of the windshield wipers ( 2 ) transparent that lie in the field of vision of the vehicle occupants or that at least partially cover the headlights.

To support sufficient strength of the Windshield wipers also allow training from a combination of different materials  to provide. In the transparent material can for example, reinforcement elements that are embedded are preferably transparent.

Fig. 2 shows an embodiment in which in the windshield wiper ( 2 ) made of transparent material channels ( 5 ) for the forwarding of windshield washer fluid are worked. The channels ( 5 ) extend before preferably in the area of a support element ( 6 ) of the windshield wiper ( 2 ) and direct the windshield washer fluid directly into the area of a wiper blade ( 7 ).

Fig. 3 shows an embodiment in which in the area of the support element ( 6 ) additional air guide elements ( 8 ) are arranged, which are also made of a transparent material. In particular, it is envisaged to manufacture the support element ( 6 ) and the air guiding elements ( 8 ) in one piece in a common manufacturing step. A particularly low visual impairment can be ensured in that both the air guide elements ( 8 ) and the support element ( 6 ) and the Wi blade ( 7 ) are made of transparent materials.

Fig. 4 shows an embodiment in which two light elements ( 9 ) are integrated in the support element ( 6 ) of the wiper. The light-emitting elements ( 9 ) can be designed, for example, as light-emitting diodes (LED), which are colorless and transparent in a deactivated state. In the case of a supply with electrical energy, the light elements ( 9 ) emit light which can be colorless or colored depending on the physical parameters in each case. If the windshield wiper ( 2 ) is designed as a rear windshield wiper of a motor vehicle, the light elements ( 9 ) can emit red light, for example, and can be used as an additional brake light or warning light. It is also conceivable, for example, to generate yellow or white light. In principle, it is also conceivable to activate different light emitting depending on different operating states. For example, it is contemplated to emit red light when performing a braking operation and to produce white light during a reverse drive. A corresponding changeover can, for example, take place via the gear shift or the gear selection.

A further embodiment consists of arranging the lighting element ( 9 ) in the region of an axis of rotation ( 10 ) of the windshield wiper ( 2 ) and coupling the light into the transparent support element ( 6 ). This helps to ensure that the windshield wiper ( 2 ) lights up evenly.

With regard to the transparent construction of the windshield wiper ( 2 ), it is in particular both intended to provide a colorless, transparent implementation and a colored, transparent implementation. It is also possible to combine the two design variants within one wiper ( 2 ). The at least partially transparent construction also includes making all of the proposed construction elements transparent. In particular, here in addition to the support element ( 6 ) and the wiper blade ( 7 ) also ge used on fastening claws, Hal teelemente, hoses, screws and small parts.

In addition to the application already explained above area in the field of automotive engineering can Use also for example in stationary loading surveillance cameras, in industrial applications in the Be rich of protective screens on machines as well as others Means of transport (for example on airplanes, omni buses, trucks, railways and ships).

Fig. 5 illustrates once again the arrangement of the wiper ( 2 ) in the area of the rear window of a motor vehicle ( 1 ). As an alternative to the functions of the windshield wiper ( 2 ) already explained when it is implemented as a rear wiper, it is also possible to provide a function as a third brake light. Depending on the conditions of approval, the relevant function can be activated either only in the rest position or when performing pendulum movements. When realizing the function as a brake light when performing pendulum movements, an increase in the attention value could be achieved. This is particularly important in rainy weather.

Likewise, the function as night lighting or the warning light function can be activated both exclusively in the parked position of the windshield wiper ( 2 ) and during the execution of pendulum movements.

The described lighting functions in the area of the windshield wiper ( 2 ) can in particular also be implemented if the windshield wiper ( 2 ) is not completely transparent, but is only transparent in some areas. The transparent training must, however, be realized at least in the area of the light radiation provided by the lighting element.

With regard to the luminous films already mentioned also thought of being actively electrically controllable to construct.

When installing a brake light in the area of the wiper ( 2 ) in the area of the rear window, there are no elaborate changes to the interior trim, which typically have to be carried out when a third brake light is installed. In addition, no separate housing is required for the brake light, since the support element ( 6 ) of the wiper ( 2 ) also realizes the housing of the third brake light. It can be a material saving he aims.

Compared to the use of conventional designs from additional brake lights is also a ver improved design.

Fig. 6 illustrates as an alternative to the embodiment in Fig. 3, the arrangement of the Luftleitelemen tes ( 8 ). The air guide element ( 8 ) extends in the longitudinal direction of the support element ( 6 ) and has a curved contour transverse to the longitudinal direction of the support element ( 6 ). Through this curved contour, transverse air flows are converted into a pressure force.

Fig. 7 shows an embodiment in which Scheibenwi shear ( 2 ) is provided with a wiper arm ( 11 ) which forms a common component together with a main balance beam ( 12 ). As a result, two secondary balance beams ( 13 , 14 ) are pivotally supported directly on the shear arm ( 11 ). The secondary balance beams ( 13 , 14 ) in turn hold a rail-like support element ( 6 ) for the wiper blade ( 7 ).

In general, the trans Parent components shown in such a way that the Components at the back of the drawing plane with regard to their edge course not in the coverage area are formed. This serves to clarify the Dar position. However, in a real embodiment due to the transparent properties all components elements visible at the same time.

To provide sufficient flexibility, a wiper arm joint ( 15 ) is arranged in the area of the wiper arm ( 11 ). The wiper arm joint ( 15 ) can be designed as a mechanical joint, but in particular it is contemplated to use a flexible and transparent joint made of plastic.

Fig. 8 shows an embodiment in which a separa ter main balance beam ( 12 ) is used, which is held by a wiper arm from the wiper arm ( 11 ). The support element ( 6 ) is constructed in this embodiment as a tension spring. The tension spring can also be made completely or partially transparent.

According to the modified embodiment in Fig. 9, the secondary balance beam ( 13 ) is supported by a balance scale beam ( 16 ). In this way, an increased adaptability to a contour profile of the assigned disk can be achieved. In particular, it is envisaged to construct both the main balance beam ( 12 ) and the secondary balance beam ( 14 ) and the balance balance beam ( 16 ) from a transparent material.

Fig. 10 and Fig. 11 show further modified forms of exporting approximately. FIG. 10 is a symmetrical Anord drying using a main beam (12) of two balance balance beam (16) and of two seconding därwaagebalken (13, 14), respectively. According to the embodiment in FIG. 11, each of the main balance beams ( 12 ) is assigned two secondary balance beams ( 13 , 14 ).

Fig. 12 shows an embodiment, in addition in the region of the wiper arm (11) Armspoiler (17) is arranged in the. In addition, it is also intended to mount a pressure spoiler ( 18 ) in the area of the main balance beam ( 12 ). Both spoilers ( 17 , 18 ) can be formed from a transparent material. The use of an arm spoiler ( 17 ) and / or egg nes pressure spoiler ( 18 ) is possible in all the embodiments shown in the figures and the conceivable variants.

Fig. 13 shows an embodiment with a swinging ver wiper arm ( 11 ) and using lighting elements ( 9 ), which are small relative to the geometry of the wiper ( 2 ). Fig. 14 shows a modified variant in which the lamp elements ( 9 ) in the area of the main balance beam ( 12 ) are arranged. The windshield wiper shown is particularly intended for use in the area of a front windshield of a motor vehicle. The display elements can be used for different purposes. In the case of a possible application, a realization as a visual parking aid is selected in which, for example, a green display indicates a sufficient available space for movement and a red display indicates critical distance conditions. It is also conceivable, for example, to make a coupling with an outside temperature detection and thereby implement a display of temperatures below the freezing point.

Fig. 15 shows a further embodiment in which the region of the main beam (12) is a Andruckspoiler (18) is positioned. It can be seen in particular that the pressure spoiler ( 18 ) has a curved contour in order to convert the acting air flow into an optimally oriented pressure force.

Fig. 16 shows a similar curved contoured Armspoiler (17) in the region of the wiper arm (11). In addition, it can be seen in this illustration that the wiper arm ( 11 ) is coupled via a base swivel joint ( 19 ) to an arm base ( 20 ). The arm base ( 20 ) is typically connected to a drive shaft. The arm base bore provided in the area of the arm base ( 20 ) is fitted with regard to its diameter and its contour shape to an associated drive shaft.

According to the embodiment in FIG. 17, the main weighing beam ( 12 ) is connected to the wiper arm ( 11 ) via a coupling element ( 21 ). The coupling element ( 21 ) is pivotably connected both to the wiper arm ( 11 ) and to a positioning strut ( 22 ). In carrying out a pivoting movement of the wiper arm (11) thereby is additionally a Schwenkbewe supply of the main beam (12) causes relative to the wiper arm (11), since the points of articulation of the wiper arm (11) and the positioning bar (22) in the region of the coupling element (21 ) have a distance relative to each other. In particular, it is contemplated that the coupling element ( 21 ) and the positioning strut ( 22 ) should also be made transparent at least in some areas.

In Fig. 18 and Fig. 19 further variants for the use of lighting elements ( 9 ) are shown. Fig. 18 shows the use of relatively small-area lighting elements ( 9 ), according to Fig. 19, a relatively large-area lighting element ( 9 ) is used.

Fig. 20 shows an embodiment using egg sprayer ( 23 ). The spray device ( 23 ) has a plurality of nozzles and is connected to a spray agent supply via a preferably transparent connecting hose ( 24 ). The spraying device ( 23 ) can be provided both for applying the spraying agent to the associated pane for carrying out a pane cleaning and for supporting self-cleaning of the transparent areas of the wiper ( 2 ). It is both possible to integrate the spray device ( 23 ) into one of the components of the windshield wiper ( 2 ) and to provide a separate arrangement. It is also conceivable to position several spray devices ( 23 ) at different locations.

Fig. 21 shows an embodiment in which the Wi scissor arm ( 11 ) from a base element ( 25 ) and an arm extension ( 26 ) is formed. In the area of the base element ( 25 ), a pressure spring ( 27 ) is positioned. The base element ( 25 ) is preferably made of tall metal. The arm extension ( 26 ) consisting of a transparent plastic material is thereby relieved from direct action of the spring force and forces in an environment of the base joint ( 19 ).

For example, it is contemplated to form the base element ( 25 ) as a hollow profile into which the arm extension ( 26 ) can be inserted. The arm extension ( 26 ) can be fixed, for example, with the aid of clamping screws ( 28 ). A transition area from the arm extension ( 26 ) in the base element ( 25 ) can be covered by a panel who the.

For providing an anti-theft protection, an electrical terminal (29) is shown in FIG. 22 is used. The function can be implemented, for example, in such a way that a fastening nut provided for the windshield wiper arm ( 11 ) is normally used to produce a connection which is not required when the nut is unscrewed. This can activate an alarm system.

According to an additional embodiment shown in FIG. 22, a shock absorber ( 30 ) can be arranged between the base element ( 25 ) and the transparent arm extension ( 26 ). The shock absorber ( 30 ) relieves the arm extension ( 26 ) from acting shock loads and limits acting torsional loads, which could possibly lead to material fatigue or material clouding.

Fig. 23 shows a wiper ( 2 ), which is provided for Anord voltage in the area of a rear window of a motor vehicle. There are several lighting elements ( 9 ) used ver. The arrangement of the light elements (9) can be accomplished, with play, that illumination is provided inwardly for realizing a parking assistance and that one or more exert outwardly directed light elements (9) their signal function in performing a braking operation. The parking aid function can be coupled using a circuit to an additional or existing distance detection using distance sensors.

In the embodiment according to FIG. 24, the light element ( 9 ) is po sitioned as an additional brake light in the region of a swivel joint of the rear windshield wiper arranged in the center relative to the vehicle width. This embodiment ensures that even with a pendulum movement of the windshield wiper ( 2 ) a constant positioning of the light element ( 9 ) is maintained relative to the vehicle.

Various measures can be implemented to support the permanent retention of the transparent property of the wiper ( 2 ). Already by choosing a suitable material, you can contribute to a permanently transparent design. In particular, the use of polycarbonate is being considered. It is also conceivable to use transparent composite materials, for example glass with a polymer coating. The wiper blades ( 7 ) can be produced from a transparent polymer or a transparent silicone. In particular, the addition of chemical additives that prevent yellowing is considered.

To ensure a transparent appearance the carries a non-reflective coating of the used Materials at. An anti-reflective coating can, for example by using a microstructured surface layer can be realized, the refractive index between between the refractive index of air and the refractive index dex of the transparent carrier material. Likewise it is conceivable to periodically apply an anti-reflective coating to make shaped microstructures that are suitable cause gradients of the refractive index.

Another way to provide an Ent reflection is the use of a porous Solid gel layer. Such a layer typically exists usually from an inorganic material that after a thermal treatment a porous submicron has structure. The resulting pores point typically a diameter of less than 20 nm on. It is also possible to use a vacuum layering process to perform an anti-reflective treatment. This creates thin anti-reflective layers upset. Layers can be used, for example made of calcium fluoride or magnesium fluoride, the An number of layers affects the degree of anti-reflection.

Another variant is the use of etching method. With the help of suitable etching agents  Microstructures generated on the substrate and through these microstructures there are reflection effects avoided. Another method is that provided for an anti-reflective layer next to arrange in a cluster that is electric greatly accelerated and to the surface of the be layered material is shot. Because of the arising high pressure and the converted into heat the anti-reflective coating combines kinetic energy layer with the carrier material.

It is also possible to have dissolved in a liquid Silicon compounds on the transparent substrate to spray al. This typically results se both an antistatic and a very hard one Coating.

When specifying and positioning the Mi Crostructures can be exploited that typically se the positioning of the wipers relative to Defi a driver within a certain range is nated. This allows a suitable contour choose an optimization of the antireflection effect be enough. In particular, it is also thought along the length of the wiper Change the orientation of the microstructures in such a way that relative to the driver, on average, an optimal one Positioning is guaranteed. Both in the Ver use of anti-reflective components as well as in the Use of conventional transparent components can be re through a suitable surface positioning a minimization relative to a driver's point of view of glare and reflection effects.  

According to a further embodiment variant, it is also included thought, alternatively or in addition to the provision a reflection-reduced surface also dirt realizing repellent properties. Especially Microstructures are particularly suitable for this net, both the desired reflection reduction as well also to provide the dirt-repellent properties len.

According to a further embodiment, it is also possible Lich, heating the transparent parts in advance hen. In particular, it is possible here through ent speaking additives or surface coatings a to provide electrical conductivity, being a resulting electrical resistance as a heating element is being used. The additives or coatings should be chosen so that the transparent Eigen are not affected.

According to a further embodiment, to realize a lifting device that the wiper leaf essentially perpendicular to the windshield lifts. Such a device avoids or ver reduces damage to the wiper blade at winterli temperatures that cause a freeze on the wind can lead protective screen. Such a lifting device device can, for example, when used in loading empire of a rear wiper also used for this with an additional implementation of a Function as a warning light a damage-free Support operation.

Another way to improve the pro Product quality is surface coatings  use to increase scratch resistance. At Can use polycarbonate as the base substance For example, transparent paint films can be used. Such paint films can also get dirty at the same time have pointing and / or anti-reflective properties.

Fig. 25 shows the use of full profiles for the main balance beam ( 12 ) and the secondary balance beam ( 13 ). It can be seen in particular that the secondary balance beam ( 13 ) in the area of its extension facing the main balance beam ( 12 ) is provided with a cross-sectional taper such that a sufficient swivel angle range is provided. The tapering of the cross section makes it possible to pivot the secondary beam ( 13 ) relatively far below the main weighing beam ( 12 ).

According to the use of cascade-like balance beams ( 12 , 13 , 14 , 16 ) shown in FIG. 26, who uses such material tapering both in the area of the secondary balance bars ( 13 , 14 ) and in the area of the balance beam ( 16 ). Corresponding constructions can also be used in the other constructions already explained for the use of balance beams.

According to a further embodiment, it is possible to arrange the pressure spring for pressing the wiper arm ( 11 ) against the associated pane at least partially in applications in the field of motor vehicle technology under half the bonnet. In the case of a correspondingly recessed arrangement of the spring, a coupling to the wiper arm ( 11 ) can take place via a steel wire. It is also basically conceivable to provide the pressure forces with the aid of transparent, resilient materials.

Other terms are sometimes used in the prior art to refer to the above part names. The main balance beam ( 12 ) is also referred to as the main bracket, the secondary balance beam ( 13 , 14 ) are also called claw lenbügel. The balance beam ( 16 ) is sometimes referred to as an intermediate bracket. Spring rails can be used for immediate mounting and stabilization of the wiper blades ( 7 ). According to the inven tion, the entire bracket system is at least partially transparent.
