Abstract

PURPOSE:To enable a door mirror and a side window to be wiped at the same time, according to a method wherein each blade mounted on the top end of each forking arm is swung by means of a motor fixed to a door inside. CONSTITUTION:A wiper driving motor 5 is fixed to the inside of a door 3a, and a four connection link mechanism consists of a crank arm 6, a rod 7 and a arm 8 sequentially connected to the motor 5, and the arm 8 is swung by means of the rotation of the motor 5. The one end 8a of the arm 8 is rotatably connected to the door 3a by means of a pin 11, and the other end forks, and blades 9 and 10 wiping a door mirror 4 and a side window respectively are mounted on the forked portions. Therefore, when the motor 5 is driven, the door mirror 4 and the side window 3 can be wiped at the same time by means of each of the blades 9 and 10 in accordance with the swing of the arm 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wiper device for the side of a vehicle having a wiper portion for a side window and a door mirror of the vehicle.

[Conventional technology]

The conventional side window wiper was developed in 1983 as shown in Figure 2.
Although the wiper blade 2 is adapted to wipe the side window 3 in conjunction with the motor 1 as in Japanese Patent No. 103948, another wiper mechanism is additionally required to wipe the door mirror 4.

[Problem that the invention seeks to solve]

When driving in the rain, raindrops fall on the side windows 3 and the door mirrors 4 at the same time, so wiping only the side windows 3 has little effect, and the door mirrors 4 also require a wiper.

[Summary of the invention]

The present invention solves this problem and will be briefly described in FIGS. 1 and 3. The wiper drive motor 5 is fixed inside the door, and although not shown, rotates when the power is turned on. A crank arm 6 connected to the motor 5, a rod 7,
The arm 8 constitutes a four-contact mechanism, and the rotational movement of the motor 5 is made into the swinging movement of the arm 8. One end 8a of the arm 8 is fixed to the corner of the door by a pin 11 as a pivot shaft. Further, the opposite side is divided into two parts, and one side has a blade 9 for wiping the side mirror 4, and the other side has a blade 10 for wiping the side window 3.

By driving the motor 5 and rotating the crank arm, the arm 8 swings, and the blade 9.10 wipes the door mirror 4 and the side window 3 at the same time.

In this way, by configuring the motor with one motor, the cost can be reduced, and since the configuration is simple, it is easy to install. Furthermore, since the side windows 3 and door mirrors 4 can be wiped off at the same time, the rear visibility can be instantly confirmed, which is safe.

[Means for solving problems]

In order to solve the above problems, the present invention provides one wiper motor (5) built in the door (3a) of the vehicle.
a power transmission part (7) that moves up and down in the vertical direction by the rotation of the wiper motor (5); and a power transmission part (7) connected to the power transmission part (7) whose rear end is connected to the door (3a).
), the arm (8) is rotatably attached to the inside of the door mirror and has a bifurcated tip end, and an arm (8) that is attached to each of the branched tips of the arm (8) and wipes the side of the door mirror (4). A wiper blade (9) and a side window wiper blade (1) that wipes the side window (3).
0).

〔Effect of the invention〕

This allows you to wipe the side windows and door mirrors at the same time, so when you want to check the rear view, you can wipe them instantly and be safe. Furthermore, since one motor is used, it is easy to store inside a door and is inexpensive.

〔Example〕

A first embodiment is shown in FIGS. 1 and 3. A motor 5 built in the door 3a rotates a crank arm 6 (not shown) by turning on power to the motor. One end 8a of the arm 8 has a rotary bearing, and a pin 1
1, it is fixed rotatably to the corner in front of the door. The arm 8 has a bearing 12 to which the loft 7 is rotatably fixed. The arm 8 is attached to the crank arm 6 by the loft 7.
are connected to form a four-way link mechanism.

The arm 8 is divided into two parts, each with a blade 9.
10 are connected, and the side windows and door mirrors can be rotated to wipe each side window and door mirror, respectively. That is, the dimensions are set so that the blade 9 is pressed against the door mirror 4 and the blade 10 is pressed against the side window 3.

[Effect]

When the motor 5 is powered on, the crank arm 6 rotates, and the rod 7 connected to the crank arm 6 drives the arm 8.

In other words, the pin 11 allows one end 8a of the arm 8 to rotate.
Because it is fixed in front of the door, the blade 9 fixed to the arm 8 swings on the opposite side of the arm 8.
and 10 wipe the surfaces in contact with each other. Also 1
There is also the advantage that only one switch is required because of the number of motors.

[Other Examples]

The blade 9 or 10 connected to the arm 8 can be used as a wiper blade for wiping curved glass to provide a mechanism for wiping the glass more effectively.

FIG. 4 showing the second embodiment shows the arm 8 after branching of the arm 8.
By making b thinner and bending it, the arm pressure P applied to the blade 9 can be set to be constant even on a curved glass surface. Furthermore, by adopting the curved blade 9a,
Even better results.

FIG. 5, which constitutes the third embodiment, is an example in which a spring method having a retainer spring 9C, similar to that of the front wiper, is adopted for setting the arm pressure.

Furthermore, a sliding cable (wire) may be used instead of the rod 7 forming the power transmission section.
