Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rear window wiper device for an automobile, and more particularly, to a rear window wiper device for an automobile in which a rear window panel is attached to the edge of a window opening so as to be openable and closable.

BACKGROUND OF THE INVENTION Some conventional automobiles are known to have a rear window panel that can be freely opened and closed so that a feeling of openness can be obtained by opening the rear window panel. In addition, when installing a rear window wiper device on a vehicle equipped with such a rear window panel that can be freely opened and closed, it is necessary to take measures such as , Showa 58
Published by Nissan Motor Co., Ltd., January 2016 Nissan Datsun Vanette, Sunny Vanette, and Cherry Vanette are set on the edge of the rear window opening. this,
The explanation will be given by taking an example of a car equipped with a back door with reference to FIGS. 1 to 8. / indicates the vehicle body, 3 indicates the back door,
The back door 3 is attached to the upper edge of the vehicle body opening via a hinge member so as to be openable and closable. The rear window panel S of the bank door 3 is attached to the upper edge of the window opening edge 6 via a hinge member 7 so as to be openable and closable. The figure shows a wiper unit, and its wiper motor 9 is disposed in the upper closed section space S of the window opening edge t, and the wiper pivot 10f is set at the upper edge of the window opening edge 2. Grade//f Upper edge outer plate 3a
It can be stored and placed on top. Wiper motor 9
has a well-known rise-up function, and when the wiper is operated, the wiper blade ttf is temporarily moved from the storage position A to the swinging start position B beyond the padding gap δ between the window opening edge 2 and the window panel S. after that,
The wiper blade // can be swung at a desired angle within the surface of the window panel S using the oscillation start position B as a reference point.

However, in such a conventional configuration, the wiper blade
When the U' fiber blade/l exceeds the parting gap δ when the blade is stored or when the wiper is operated, the blade rubber 72 is moved as shown in FIG.
The tip of the grade rubber 12 falls into the parting gap δ, and the motor driving force forcibly pulls up this blade rubber 12 from the parting gap δ, causing the tip of the grade rubber 12 to be pried and damaged significantly. There was a problem that the wiping cleaning effect of the panel S surface was impaired.

Purpose of the Invention In view of the conventional situation, the present invention provides a technology to prevent the tip of the blade rubber from falling into the parting gap between the window opening edge and the rear window panel, thereby protecting the blade rubber and impairing the wiping cleaning effect. The purpose is to provide a rear window wiper system* for automobiles that do not have one.

Effects of the Invention In order to achieve the above object, the present invention includes a slider portion attached to the end of the wiper blade to prevent the blade rubber from falling into the parting gap between the rear window panel and the edge of the window opening. It is.

Embodiments Hereinafter, embodiments of the present invention will be described in detail, taking as an example an automobile fully equipped with a back door, and assigning the same reference numerals to the same parts as those of the conventional structure.

In Figures 4 to 8, the wiper motor of the wiper unit Sahaso? A lower closed section space S with a wide closed area at the window opening edge 6 of the back door 3.

The wiper pivot 10f is set at the lower edge of the window opening edge 6, and the wiper blade/2fc
It is designed so that it can be stored and placed on the outer plate 3b at the lower edge. This wiper motor 9 moves the wiper blade l- once from the retracted position fA to the window opening edge t when the wiper is operated.
It is similar to the MIF standard that it has a rise-up function to move to the swing start position B beyond the parting gap δ between the window panel 3 and the window panel 3.

Here, slider portions 73 are attached to both ends of the front convex wiper grade ii to prevent the blade rubber 2 from falling into the parting gap δ.

In the case of stripping, this slider part 3 is integrally molded on both ends of the entire blade rubber 7-, and the slider part 13 has an arcuate edge 4' at the lower edge, and is formed in a substantially circular shape on its side. , the arcuate edge lq gold dab 1/-dragperf 2 when the tip flannel is wiped, the arcuate edge lq also rises slightly from the surface of the window panel S.

Next, the operation of the above embodiment apparatus will be explained in detail.

When the wiper is operating or retracted, the wiper grade/l is adjusted to the pivot IO by the rise-up operation of the wiper motor between the retracted position A parallel to the parting gap δ and the swing start position B, as shown in Fig. 6. will be moved around. Therefore, the wiper blade // is not parallel to the parting gap δ in the parting gap 6 portion, and the wiper blade /l is in a posture diagonally intersecting the parting gap δ, as shown by the chain line in FIG. The parting gap δ is exceeded. However, if the slider part 73 is not attached to both ends of the wiper blade/l, when the end of the blade rubber 72 reaches the parting gap δ, the tip of the end will touch the edge of the window panel S in the parting gap δ. The movement of the tip of the blade rubber 72 is restricted by these mating edges, and the tip of the blade rubber 72 is brought into the state shown in FIG. 3 above with the parting gap δ. I feel depressed.

On the other hand, when the wiper blade // is provided with a slider part /Q- at both ends as in this embodiment, when the wiper blade // end reaches the parting gap δ, the arcuate edge of the slider part 13 As shown in FIG. 7, the arcuate edge /G slides over the edge of the window panel S or the edge of the window opening edge 6, and the blade moves. The tip of the rubber blade 72 is completely prevented from falling into the parting gap δ, and the tip of the blade rubber 7 is slid and guided on the window panel surface S or the outer plate 3b surface of the window opening edge B, and δ can be exceeded smoothly.

Furthermore, if the wiper motor is disposed in the lower closed cross-sectional space S of the window opening edge as in this embodiment, the lower closed cross-sectional space S has a large closed area, so that the wiper motor can 9 can be arranged with a margin, and there is an advantage that there is no need to make any design changes such as making the closed section ram wider. In other words, in the conventional device shown in FIG. 1.2, in order to arrange the wiper motor 7 in the upper closed cross-section space B1, it is necessary to expand the closed cross-section space 81 downward. However, in this embodiment, as shown in FIG. 4, the area of the window panel 5 can be reduced in the vertical direction to an upper closed section space 81, and the area of the window panel 5 can be reduced by that amount. It has the advantage of expanding the area and expanding the rear visibility.

In the embodiment shown in FIG. 9.10, the slider part/3A is formed separately from the blade rubber 72 into an end cap type. This slider part/JA has at least both corners of the lower part rounded and formed into a substantially triangular shape on the sides, and has an arcuate edge A on the bottom edge as in the case of the previous embodiment. There is.

The slider part /JA has a groove /3f matching the end face shape of the wiper blade /l, and the slider part /JA has a groove /3f that matches the end face shape of the wiper blade /l
/Press and fit into the end part by its own elasticity and adhere with an appropriate adhesive. Although it is functionally similar to the previous embodiment, this embodiment has the advantage that it can also be applied to existing wiper blades.

The embodiment shown in FIG. 11.12 is a wiper blade ll
The metal blade body //a has slider parts at both ends /J
B'i is integrally molded. A strip //b is extended on both sides of the end of the blade body //, and each strip ti b'
1 is bent downward to have an arcuate edge /4'B at the bottom edge and rounded corners on both sides to form a slider part /JB. The ends of each strip //b are curled inward and abutted to prevent them from getting caught on the edges of the in-toe panel S or the edges of the window opening edge 6. In this case, it is of course possible to provide a resin coating or the like on the lower surface of the slider portion/JB to prevent damage to the window panel surface and the opening edge outer panel.

Here, as shown by the broken line in FIG. 4, on the lower edge outer plate 3b of the window opening edge 6, there is a disconnection loop shape that covers the wiper blade l/end portion from the windshield pivot 10. By attaching a hood/6t to the wiper unit, the appearance can be improved and clothes etc. can be prevented from getting caught in the wiper unit. Further, it is desirable that the entire coating film protection finisher 77 be attached to the blade rubber sliding surface of the outer plate 3b described in 11J.

Although the present invention has been applied to an automobile completely equipped with a bank door, it can be similarly applied to a vehicle in which the rear window panel itself constitutes the entire back door.

Effects of the Invention As described above, according to the present invention, it is possible to completely prevent the tip of the blade from falling into the parting gap between the rear window panel and the edge of the window opening. It has a great practical effect in that it can be maintained without any damage to the wiping and cleaning effect of the rear window panel.
