Description

Detailed Description of the Invention (Industrial Application Field) The present invention is directed to raising and lowering a rectifying plate to prevent wipers from lifting up during use, which occurs when a car is running at high speed or in strong winds, and to raise and lower a rectifying plate to prevent wipers from rising when the wipers are not in use. The present invention relates to a wiper storage device for an automobile, which links the opening and closing of a hood that covers the blades.

(Prior Art) When automobile wipers are driven at high speeds or in strong winds, the windshield blows against the windshield, causing the wipers to float up and become unable to wipe the glass surface, which may impede driving.

For this reason, some cars are already equipped with a rectifying plate at the rear of the bonnet that slopes rearward and upward, parallel to the bottom of the windshield, to direct strong winds blowing from the front upwards in front of the windshield. There is something I did.

(Problems to be Solved by the Invention) However, conventional rectifying plates are fixed to the bonnet and exposed at all times, which impairs the beauty of the car, increases air resistance, and is an eyesore when driving when wipers are not used. It also produced unpleasant wind noise when driving at high speeds.

The present invention includes a rectifier plate and a hood for covering the wiper blade when the wiper is not in use.
When the hood is opened, the current plate stands up and is ready for use, and when the hood is closed, the current plate is folded down by the hood and stored under the hood. The object of the present invention is to provide a wiper storage device for an automobile that solves the above problems.

(Means for Solving the Problems) In the present invention, a window hole capable of storing a wiper blade is provided in the rear part of the bonnet close to the windshield, and a hood capable of closing the window hole is provided. The hood is provided on the vehicle body so as to be movable between a closed position where the hood is closed and an open position where the hood is retracted below the bonnet, and a drive means is provided on the vehicle body for moving the hood between the closed position and the open position. When the hood is opened, the hood stands up in a tilted state facing rearward and upward from the window hole, and when the hood is closed, the hood applies a biasing force in the erecting direction to the rectifying plate, which is caused to fall downward, so that it is applied to the vehicle body. It is characterized by being pivoted so that it can be raised and lowered freely.

A slider 17 is fitted behind the sliding fitting 15 in the guide groove 9 with enough room to allow it to tilt slightly up and down.

Reference numeral 18 denotes a hood having the same size as the window hole 5, and mounting plates 19 that are close to and parallel to the outer surface of the guide rail 6 are vertically provided on the lower surfaces of both sides thereof.

In the center of the mounting plate 19, an inclined hole 20 facing upward is bored in the front, and a guide pin 21 facing inward is provided in the front part, and a guide pin 21 facing inward is provided in the front part.
It is fixed to 7.

The engagement pin 16 engages with the inclined hole 20, and the guide pin 21 fits into the notch groove 7 of the guide rail 6 when the hood 18 closes the window hole 5.

A pressing arm 22 facing rearward is pivotally supported at the front end of the inner surface of the guide rail 6 with a pin 23, and a long hole 24 is bored at the rear end of the pressing arm 22.

At the inner and lower part of the central part of the guide rail 6, the front upper part and the rear upper part of the pivot plate 25 installed upright on the vehicle body 1 are as follows.
A swing arm 26 facing rearward and a support arm 27 facing forward are pivotally supported by a pin 28 and biased upward by a torsion spring 29, respectively.

A long hole 30 is bored in the center of the swinging arm 26, and a rectifying plate 31 is mounted at the rear thereof.

The long hole 24 of the pressing arm 22 and the long hole 30 of the swing arm 26 are engaged with a pin 32 fixed to the front end of the support arm 27.

Figures 1 and 2 show when wiper 4 is not in use.
This figure shows a state in which the blade is stored horizontally in the window hole 5 and the top surface is closed with the hood 18.
