Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wiper for wiping off foreign matter such as rainwater or snow adhering to the glass surface of a side window of an automobile.

[Prior Art] Nowadays, the triangular corner portion of the front side window of an automobile tends to be under negative pressure while the vehicle is driving, and therefore rainwater or snow tends to adhere to the glass surface of this portion in the form of droplets. For this reason, the door mirror installed in this area becomes difficult to see from the driver's seat, which may impede safe driving.
Therefore, when a wiper commonly used for windshields is attached to the upper sash 3' of the side window 1' as shown in FIG. Since the tip of the weather strip collides with the weather strip 4' on the side window 1', there is a drawback that a triangular unwiped portion 5' is left on the lower side of the window 1'.

[Purpose of the invention] This invention solves the conventional problems as mentioned above,
The purpose of the present invention is to provide a side window wiper for automobiles that is nimble and allows safe driving.

[Structure of the invention] In the present invention, a case with an open rear side is fixed to the lower outer surface of the sloping upper sash of the side wound, and a wiper blade is attached to the case, and a wiper blade is attached to the upper sash at the upper limit, and a case is attached to the upper sash at the lower limit. A link mechanism that operates in a fan shape is installed in parallel to the lower weather strip of the side window,
This link mechanism consists of a link connected to the wiper blade, a main arm and a sub-arm whose tips are connected to this link, the base of the main arm and the base of the sub-arm are pivoted to the case, and the base of the main arm is It is connected to a drive mechanism.

[Embodiment] To explain the embodiment shown in FIGS. 1 to 6, numeral 1 is a side window provided at the upper part of a front side door 2 of an automobile, and the slanted upper sash 3 of this side window 1 and The base 5a of the door mirror 5 is attached to the triangular corner formed by the substantially horizontal lower weather strip 4. A shows a base 6 and a cover 7 fixed to the outside of the lower part of the upper sash 3 in correspondence with the door mirror 5.
The lower bent edge 6a of the base 6 is engaged with the lower inner edge of the upper sash 3, while the stopper 8 is screwed at intervals to the upper bent edge 6b. After the portion 8a is engaged with the upper inner edge of the upper sash 3 as shown in FIG. 3, the base 6 is fixed to the upper sash 3 by tightening the screw. In addition, the cover 7 has a pair of left and right hook-shaped support edges 7a, 7a protruding from the inside of the top surface, which are fitted onto the outsides of the left and right side edges 8b, 8b of the clasp 8, and the base
Installation is underway. B is a link mechanism disposed in case A together with the wiper blade 9, and is made up of a link 11 pivoted to the back of the wiper blade 9 by a shaft 10, and a main arm 12 and a sub-arm 13 whose tips are connected to this link 11. The base of the main arm 12 and the sub arm 13
The base end of the main arm 12 is pivotally attached to the base 6, and the base end of the main arm 12 is connected to the output shaft of a drive mechanism C mounted inside the case A by a crank 14. still,
As shown in FIG. 6, the fulcrum a of the sub-arm 13 to the base 6 is the fulcrum b of the sub-arm 13 and the link 11 when it is located on the sash 3, and the fulcrum of the sub-arm 13 and the link 11 when the lower limit is activated. c.
The wiper blade 9 is set on the perpendicular bisector d of the line segment connecting It is configured to abut in parallel with the lower weather strip 4 at the bottom. D is a support device for the wiper blade 9 fixed on the base 6, and the support device D includes a fixing part 16 fixed to the base 6 and this fixing part 1.
It consists of a support plate 17 which is rotatably supported by the support plate 6,
A receiving groove 19 for holding the protruding shaft 18 protruding from the link 11 is provided at the tip of the support plate 17, and a coil spring 21 is mounted on the support shaft 20 which pivotally supports the support plate 17, as shown in FIG. As shown, when the wiper blade 9 is not supported, the support plate 17 maintains a prone state. Furthermore, code 2
2 is a weather strip attached to the upper sash 3, and 23 is the same glass run.

Since one embodiment of the present invention has the above-mentioned configuration, when the main arm 12 is operated by the drive mechanism C in the state shown in FIG. 1, the wiper blade 9 is supported by the link mechanism B and moves downward. It starts, comes off the support plate 17 of the support device D, is exposed through the opening 15 of the case A, and descends by pressing against the glass surface of the side window 1 while being parallel to the upper sash 3, and then touches the lower weather strip 4. After making contact in a parallel state, it starts to rise and comes into contact with the lower surface of the upper sash 3 in a parallel state, and the protruding shaft 18 protruding from the link 11 engages with the receiving groove 19 of the support plate 17, and the support plate 1
Since the wiper blade 7 is made to stand up, the wiper blade 9 is held stably within the case A while being held by the support plate 17.

[Effects of the invention] As described above, the automobile side window wiper according to the invention has a case fixed to the inclined upper sash of the side window, and a wiper blade and a link mechanism connecting the wiper blade to the case. This link mechanism allows the wiper blade to accurately wipe between the upper sash and the lower weather strip without leaving any residue.
Water droplets and snow adhering to the side window glass surface during rain or snowfall are reliably removed, making it easy to check the rear visibility using the door mirrors, and therefore allowing for nimble and safe driving. It is something. Moreover, since the wiper blade and link mechanism are always housed inside the case, they do not get in the way when washing the car.Also, since the case is open at the rear, the wiper blade wipes away rainwater etc. Even if it is lifted, it immediately flows downward and is not trapped inside the case, so it has a special effect in that there is no risk of rust inside the case.
