Brief description of the drawings
Other advantages are provided by following brief description of the drawings.Two embodiment of the present invention shown in the drawings.Accompanying drawing, specification sheets and claims comprise multiple features of combining.Professional and technical personnel in the field also can and be combined into other significant combinations according to the single described feature of object.
In accompanying drawing:
Fig. 1 shows the lateral plan with the swept area of wiper blade of wiper strip device;
Fig. 2 show according to the section-drawing of wiper strip device of the present invention and
Fig. 3 shows according to the section-drawing of another embodiment of wiper strip device of the present invention.
Detailed description of the invention
Fig. 1 shows the swept area of wiper blade 28a with good grounds wiper strip device of the present invention.This swept area of wiper blade 28a vehicle glass 32a that is provided for swiping.For this reason, described wiper strip device has wiper strip 10a, and described wiper strip comprises scrapes water rib 12a.Scrape scraping on the surperficial 34a that water rib 12a snows at vehicle glass 32a in running state and the liquid existing on clean vehicle glass 32a thus or solid, for example rainwater or.
If swept area of wiper blade 28a moves on vehicle glass 32a, the water rib 12a that scrapes of wiper strip 10a tumbles around longitudinal axis, and the longitudinal direction 36a that described longitudinal axis is parallel to wiper strip 10a longitudinally extends and extends in other words.In order to support and to scrape water rib 12a movably, described wiper strip 10a has the contact pin of tumbling 38a, and this contact pin of tumbling is flexibly constructed.
For stabilization and shaping, wiper strip device comprises spring rail 18a.Spring rail 18a is made up of spring steel.On spring rail 18a, be furnished with windscreen element 30a, described windscreen element is provided for barrier effect to the wind and for making wiper strip 10a match vehicle glass 32a of travelling on wiper strip device.Windscreen element 30a extends in whole longitudinal extension of spring rail 18a.Windscreen element 30a is connected in locking manner with spring rail 18a material.But it is also conceivable that at this, by material, sealed and/or shape is sealed couples together with wiper strip 10a for windscreen element 30a.
Figure 2 illustrates the section-drawing of wiper strip device.Windscreen element 30a is because simple and clear reason is not shown.Wiper strip 10a comprises that band is useful on the spring rail passage 14a of the housing region 16a of spring rail 18a.Spring rail passage 14a is configured in unlimitedly and deviates from the side 20a that scrapes water rib 12a.
Spring rail passage 14a has two opposed channel side wall 40a, 42a.In addition, spring rail passage 14a has passage basal wall 44a, and this passage basal wall forms passage bed.Described channel side wall 40a, 42a are contiguous on passage basal wall 44a.Channel side wall 40a, 42a and passage basal wall 44a enclose respectively angle at 45 °.Described housing region 16a is limited by channel side wall 40a, 42a and passage basal wall 44a.Spring rail 18a is inserted in spring rail passage 14a and shape is resisted against on channel side wall 40a, 42a and passage basal wall 44a in locking manner.
The housing region 16a of spring rail passage 14a has tapered portion 24a towards deviating from the direction 22a that scrapes water rib 12a.By this tapered portion 24a, spring rail channel cross-section is diminished towards deviating from the direction 22a that scrapes water rib 12a.Tapered portion 24a stepless terrace land structure.Channel side wall 40a, 42a attenuate spring rail passage 14a linearity.But also can consider at this, use other for professional and technical personnel in the field, to prove significant tapered portion, the tapered portion of for example stair-stepping or dentation.Spring rail passage 14a dovetail shaped ground structure.These two channel side wall 40a, 42a have equal length at this.
Spring rail 18a has the spring rail cross-sectional plane corresponding with spring rail channel cross-section.Therefore, spring rail 18a fills up spring rail passage 14a completely.
Another embodiment of the present invention shown in Figure 3.Explanation is below limited to the difference between embodiment substantially, wherein can be with reference to the explanation to the first embodiment about the feature remaining unchanged and function.In order to distinguish embodiment, the alphabetical a in the Reference numeral of the embodiment in Fig. 1 and 2 is replaced with to the b in the Reference numeral of embodiment of Fig. 3.About the member of same tag, especially about the member with same reference numerals, in principle can be with reference to the accompanying drawing of the first embodiment and/or explanation.
The spring rail passage 14b of wiper strip 10b has slightly circular spring rail channel cross-section.Spring rail passage 14b comprises unique circular bending conduit wall 46b.Spring rail passage 14b is configured in unlimitedly and deviates from the scraping on water rib 12b of wiper strip 10b.On conduit wall 46b, be furnished with reinforcing element 26b.This reinforcing element 26b is made up of the material harder than wiper strip 10b.Housing region 16b for spring rail 18b is limited by reinforcing element 26b.This reinforcing element 26b and wiper strip 10b are with coetrusion manufacture.But it is also conceivable that at this, use other for professional and technical personnel in the field, prove significant, for method of attachment that reinforcing element 26b and wiper strip 10b are linked together, especially as jet method, adhering method and/or welding method.
In spring rail passage 14b, insert spring rail 18b.This spring rail 18b has arch circular arc, slightly circular, and it is resisted against on reinforcing element 26b.Wiper strip 10b supports swingably with respect to spring rail 18b thus.Avoid being in the illustrated embodiment formed in other words the contact pin of tumbling water rib 12b, independent of scraping on wiper strip 10b for supporting swingably wiper strip 10b.
