Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle wiper device.

[0002]

2. Description of the Related Art In a region where a large amount of snowfall occurs in winter, when a vehicle is parked outdoors during a snowfall or in a weather when it is likely to snow, a wiper fixing arm is used for fixing the wiper and the vehicle. In general, the arm is erected so that the wiper does not bend due to the weight of snow accumulated on the contact surface with the glass surface, and the wiper is floated above the glass surface. In particular, the windshield wipers of passenger cars are supported by the bearing support at the bottom of the windshield even if snow is piled up, but the rear windshield wipers at the rear and truck wipers do not have bearings at the bottom and the weight of the snow wipes the wipers. May break off. Therefore, the operation of raising the wiper as described above must be always performed when the vehicle is left outdoors for a long time.

However, since the work of raising the wiper is performed manually after getting off the vehicle, this work is very troublesome and troublesome, especially when it is raining or snowing.

An object of the present invention is to provide a vehicle wiper device which solves the above problems.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

The vehicle 1 is provided with a wiper levitation device 4 for fixing the wiper 3 which slides back and forth on the glass surface 2 of the vehicle 1 from the glass surface 2 to a floating state, and an operation switch 5 of the wiper levitation device 4 is provided in the vehicle 1. The present invention relates to a wiper device for a vehicle, which is provided at a position where a driver sitting in the driver's seat 10 can operate while sitting in the driver's seat 10.

[0007]

[Operation] The driver sitting in the driver's seat 10 in the vehicle 1 is
When the operation switch 5 of the wiper levitation device 4 is operated while seated on, the wiper 3 is fixed in a floating state from the glass surface 2 of the vehicle 1.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show a preferred embodiment of the present invention, in which a wiper levitation device 4 for fixing a wiper 3 which slides back and forth on a glass surface 2 of a vehicle 1 from the glass surface 2 in a floating state is shown. 1 and the operation switch 5 of the wiper levitation device 4 is provided in the vehicle 1.

In the wiper levitation device 4, a piston 4B projecting a cylinder 4A from the cylinder 4A by hydraulic control is provided in the vicinity of a connecting portion between the wiper 3 and an arm 9 for connecting and fixing the wiper 3 to the glass surface 2 of the vehicle 1. The piston 4B protruding from the cylinder 4A presses the glass surface 2 so that the wiper 3 is lifted from the glass surface 2 and fixed in a floating state. It is a thing.

An operating switch 5 for activating the wiper levitation device 4 is disposed in front of the driver's seat 10 in the vehicle 1, and if the driver extends his / her hand while sitting in the driver's seat 10, the operating switch 5 is activated. To be able to operate.

In this embodiment, the motor 8 for sliding the wiper 3 back and forth is connected to the operation switch 5,
By operating the operation switch 5, the motor 8 is interlocked and is fixed at a position where the wiper 3 is in a vertical (vertical) state.

Since this structure is adopted, the snow cover area is smaller when the wiper 3 is laid down horizontally than when it is laid down horizontally, so that the effect of further preventing bending of the wiper 3 can be expected.

Further, in this embodiment, the vehicle 1 is provided with a control unit 6 for controlling the operation of the above-mentioned two points by operating the operation switch 5, and the control unit 6 allows the driver to sit on the driver's seat 10 in the vehicle 1. When the driver operates the operation switch 5 provided in the front part of the driver's seat 10 while sitting on the driver's seat 10, the wiper 3 is first fixed vertically on the glass surface 2, and then the wiper levitating device 4 is attached. Is operated to fix the wiper 3 in a floating state above the glass surface 2.

Therefore, by simply operating the operating switch 5 provided in the front portion of the driver's seat 10 in the vehicle 1 while sitting on the driver's seat 10, the wiper 3 is automatically moved to the glass surface 2 by the above operation.
Therefore, it is not necessary to manually stand up the wiper 3 after going down to the outside of the vehicle 1 as in the conventional case, which is extremely practical.

The present invention is not limited to this embodiment, and the cylinder 4A of the wiper levitation device 4 is provided near the base of the arm 9 so that the wiper 3 is fixed at a position that is largely levitated from the glass surface 2. Can be configured to
The wiper levitation device 4 may be configured by other structures.

Reference numeral 7 in the drawing is an oil hose for introducing oil into the cylinder 4A under the control of the control unit 6.

[0017]

Since the present invention is constructed as described above, the wiper is automatically fixed in a floating state from the glass surface of the vehicle by operating the operation switch to operate the wiper levitating device. Since this operating switch is installed in the vehicle at a position where the driver sitting in the driver's seat can operate it while sitting in the driver's seat, it does not have to go out of the vehicle and raise the wiper by hand as in the past. In addition, the wiper device of the vehicle is convenient and extremely practical because the wiper is fixed in a floating state from the glass surface.
