Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear wiper storage device for a vehicle, and more particularly, to a slider for riding on a cam surface formed on a step liner at a connecting portion between a blade and an arm to utilize the riding action of the slider. The present invention relates to a storage device in which a blade is floated and retracted outside a glass region to store a rear wiper.

[0002]

2. Description of the Related Art As a conventional rear wiper storage device, a slider mounted on a cam surface formed on a step liner is provided at a connecting portion between a wiper blade and an arm, as shown in Japanese Patent Publication No. 64-6062.
There is one in which the wiper blade is floated and retracted outside the area of the rear window by using the riding action of the slider.

In such a conventional storage device, a stopper is provided at the terminal end of the cam surface of the step liner so as to contact the tip of the slider and regulate the maximum riding amount of the slider, and the slider is pressed against and held by the stopper. However, the storage stability of the rear wiper cannot be said to be sufficient, for example, the slider floats up from the step liner due to the influence of vehicle running vibration or wind pressure, causing fluttering.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is an exploded perspective view showing an embodiment of a vehicle rear wiper storage device according to the present invention, FIG. 2 is a perspective view showing a relationship between a slider and a block rubber and a step liner, and FIG. 3 is a sectional view showing a rear wiper storage state. FIG. 4 is a perspective view of the mounting portion of the slider as seen from below,
FIG. 5 is a sectional view showing a relationship between the mounting portion and a mounting hole provided on the vehicle body side in the same manner.

In these figures, a glass 3 is attached to a rear window 2 provided on a rear door 1 attached to the rear end of the vehicle so that the glass 3 can be moved up and down. The rear wiper 4 for wiping the glass 3 is a pivot 5 arranged below the rear window 2.
The arm 6 has a base end attached thereto. Then, by attaching the wiper blade 7 to the tip of the arm 6, the pivot 5 is reciprocally rotationally driven by a wiper motor (not shown) to reciprocally swing the arm 6, and the wiper blade 7 attached to the tip is attached to the surface of the glass 3. A predetermined wiping action is performed by reciprocating along.

A step liner 8 is provided near the lower peripheral edge of the rear window 2, and a slider 9 projecting toward the step liner 8 is provided with an arm 6 and a wiper blade 7.
When the wiper is not used, the wiper blade 7 is floated and retracted outside the area of the rear window 2 by utilizing the riding action of the slider 9 on the cam surface 10 formed on the step liner 8 when the wiper is not used. I am trying to do it.

A cam surface 10 provided on the step liner 8
On one side near the end of the slider 9, a protrusion 11 is provided rearward in the riding direction of the slider 9, that is, substantially toward the center of the rear window 3 to form a recess 12 that opens rearward in the riding direction of the slider 9. A block rubber 13 that fits into the recess 12 when the slider 9 rides up to the end of the cam surface 10 is provided adjacent to the slider 9. The step liner 8 and the slider 9 are made of a hard resin material, and the block rubber 13 is made of a viscoelastic material such as butyl rubber.

Further, a leg portion 14 is provided substantially at the center of the back surface of the step liner 8, the tip of the leg portion 14 is formed by folding back toward the back surface of the step liner 8, and a step is formed at the folding tip end portion of the leg portion 14. The part 15 is formed. Then, the convex mounting hole 1 having the same width as the left and right width of the leg portion 14 is formed.
By forming 6 on the outer 17 of the rear door 1, as shown in FIG. 3, the leg portion 14 is fitted into the wide portion of the mounting hole 16 and the step portion 15 at the tip thereof is provided on the edge of the narrow portion of the mounting hole 16. By elastically engaging, the repulsive force of the leg portion 14 is utilized to hold the step liner 8 in the mounting hole 16 in an engaged and held state without rattling. 18 is a packing sandwiched between the lower surface of the step liner 8 and the outer 17, and 19 is a glass run.

In the rear wiper storage device for a vehicle having such a structure, when it is necessary to wipe the glass 3 as in running in the rain, a wiper motor (not shown) is driven. Then, since the pivot 5 reciprocally rotates to reciprocally swing the arm 6, the wiper blade 7 attached to the tip of the arm 6 reciprocates along the surface of the glass 3 to perform a predetermined wiping action.

When the need for wiping disappears, a stop operation is performed. Then, the wiper motor is activated based on a signal from a control circuit (not shown), and the arm 6 is swung greatly to a lower position beyond the normal wiping range. For this reason, when the stop operation is performed, the wiper blade 7 moves greatly close to the step liner 8 and the slider 9 rides on the cam surface 10 of the step liner 8.

Since the wiper motor continues to move the arm 6 in the same direction even after the slider 9 rides on the cam surface 10, the lifting action of the cam surface 10 and the movement of the arm 6 lift the wiper blade 7 from the glass 3. Move to the lower area of the rear window 2 in the state. When the slider 9 moves to the terminal end of the cam surface 10 in this manner, the block rubber 13 provided on the wiper blade 7 fits into the recess 12 formed by the projection 11, and at the same time the wiper motor stops and the arm 6 moves. Hold in position.

Therefore, unless the arm 6 is returned, the block rubber 13 is fitted and held in the recess 12, and the wiper blade 7 is securely held by the step liner 8. Therefore, even when the traveling vibration or wind pressure of the vehicle is applied, the step liner 8 causes the wiper blade 7 to move.
Does not float up and does not cause fluttering, which improves the storage stability of the rear wiper.

When the wiping action is required, the starting operation is performed. Then, the wiper motor is activated based on a signal from a control circuit (not shown) to move the arm 6 to the rear window 2
In order to move the wiper blade 7 to the side, the block rubber 13 comes out of the concave portion 12, and the slider 9 moves along the cam surface 10 to return the wiper blade 7 onto the glass 3. Then, thereafter, the wiper blade 7 reciprocates within a predetermined range until a stop signal is given to perform a predetermined wiping action.

In the above embodiment, the slider 9
Although the block liner 13 is provided on one side of the base end to reduce the size of the step liner 8, block rubbers are provided on both sides of the slider 9 so that the holding force of the step liner 8 can be further increased. . In addition, in the embodiment, the leg portion 14 provided on the back surface of the step liner 8 is elastically engaged and held in the attachment hole 16 provided in the outer 17 of the rear door 1 without rattling to improve the workability of attaching the step liner 8. However, the shapes of the legs 14 and the mounting holes 16 are not limited to those of the embodiment.

[0017]

As is apparent from the above description, according to the present invention, the block rubber provided on the wiper blade is fitted into the recess provided on the step liner to hold the wiper blade. In addition, the wiper blade does not float up from the step liner due to traveling vibration or wind pressure to cause fluttering, and the storage stability of the wiper blade is improved. Further, since the concave portion for fitting the block rubber is opened rearward in the riding direction of the slider, there is no possibility of hindering the riding of the slider on the cam surface of the step liner and the detachment from the step liner.
