Description

The present invention relates to a device having an effect of preventing deterioration of the wiper rubber, preventing the windshield from becoming dirty when the wiper is operated, and preventing damage by providing a gap by floating the wiper rubber from the windshield when the wiper is stopped. ..

The wiper reciprocates while pressing the wiper rubber against the windshield or the rear glass to wipe off rainwater or snow on the windshield or the rear glass. The wiper rubber is pressed against the windshield or the rear glass with a predetermined pressure. When the wiper is stopped in this state, the wiper rubber is stopped while pressing the windshield or the rear glass. The wiper rubber pressed against the windshield or the rear glass is deformed so that the tip portion is curved. The wiper rubber that is stopped by pressing against the windshield or the rear glass in a deformed state deteriorates and the wiper function cannot be exhibited. Further, in the wiper that presses the wiper rubber against the windshield or the rear glass to stop, dust such as earth and sand accumulates between the wiper rubber and the windshield or the rear glass. If the wiper is operated in this state, the windshield or rear glass may be damaged in the case of earth and sand. In the case of sticky dust, the glass may be soiled by rubbing it on the windshield or the rear glass. Damaged or dirty windshields or rear glass will result in poor visibility and unsafe driving.

As the prior art of this kind, there is Japanese Patent Application Laid-Open No. 2010-64659, but it is necessary to manually float the wiper, and after operating the wiper from the floating state, it is necessary to further manually float the wiper at the stop position. There is. It's a tedious task when it's raining or snowing. Since the present invention always floats the wiper rubber from the windshield or the rear glass at the wiper stop position to create a gap, it also has the effect of removing dust smaller than the gap. In addition, there is no need to manually float the wiper, so there is no hassle.

A normal wiper that does not have a device to float the wiper can extend the life of the wiper rubber and reduce damage and dirt on the glass by regularly cleaning the windshield or rear glass and cleaning the wiper rubber. It may be possible, but it's annoying.

There is a previous request to manually float the wiper while the wiper is stopped to make a gap between the wiper rubber and the windshield and the rear glass, but after operating the wiper, manually float the wiper while the wiper is stopped and lift the wiper rubber to the windshield. It was necessary to make a gap with the windshield and the rear glass. In this invention, it is not necessary to manually make a gap between the wiper rubber and the windshield or the rear glass when the wiper is stopped, and when the wiper stop position is reached, the wiper rubber can be automatically made a gap between the windshield and the rear glass. It can be done, and there is no problem with the function of the wiper.

In order to solve the above-mentioned problems, the present invention is a device that floats the wiper rubber from the front glass or the rear glass by floating the wiper arm (4) at the stop position to open a gap with the front glass or the rear glass. If the sliding pipe (1) is fixed or attached to a part of the arm (4) and the front glass is in a direction substantially parallel to the moving direction of the sliding pipe (1), it is on the cowl top side at the boundary between the cowl top and the front glass. The wiper arm (4) is gradually lifted by the sliding pipe (1) sliding up on a floating table (2) of the same width that is glued or fixed with the thinner side as the tip, and with the rear glass. If there is, the sliding pipe (1) is fixed or attached to a part of the wiper arm (4), and the thin side is attached or fixed at the tip in a direction substantially parallel to the moving direction of the sliding pipe (1). The wiper arm (4) gradually floats as the sliding pipe (1) slides up on a floating table (2) of the same width, and the wiper rubber floats from the front glass or rear glass at the wiper stop position. Alternatively, the present invention provides an automobile wiper floating device characterized in that a gap is formed with the rear glass, the normal wiper function can be maintained when the wiper needs to be operated, and the wiper does not need to be manually floated at the stop position.

By floating the wiper rubber in the stopped state and creating a gap with the windshield and rear glass, it is possible to prevent the wiper rubber from being pressed by the windshield and rear glass and deteriorating. In addition, since the accumulation of earth and sand and the accumulation of sticky dust on the wiper rubber portion are reduced, the windshield and rear glass are less likely to be damaged or soiled due to the reciprocating motion of the wiper.

It is a device that floats the wiper rubber from the front glass or the rear glass by floating the wiper arm (4) at the stop position to open a gap with the front glass or the rear glass, and a sliding pipe (slip pipe (4) in a part of the wiper arm (4). 1) is fixed or attached, and the sliding pipe (1) is attached or fixed on a floating table (2) of the same width with the thinner side as the tip in a direction substantially parallel to the moving direction of the sliding pipe (1). As the wiper slides and rises, the wiper arm (4) is gradually lifted, creating a gap with the front glass or rear glass, and when the wiper needs to be operated, the normal wiper function can be maintained manually at the stop position. It forms an automobile wiper floater, characterized in that the wiper does not need to be floated.

As shown in FIG. 2, after cutting the impact-resistant PVC pipe VP13 (outer diameter 18 mm) that serves as the sliding pipe (1) to 40 mm, a veneer plate with a width of 18 mm, a length of 40 mm, and a thickness of 2 mm is attached so that it can be easily adhered to the wiper arm. After adhering in parallel to the longitudinal direction of the impact-resistant PVC pipe VP13, it was adhered to the inside of the wiper arm, and the gap between the wiper arm and the impact-resistant PVC pipe VP13 was filled with an adhesive and fixed. The tip of the sliding pipe (1) should have an arc shape so that it can slide smoothly with little impact on the floating table (2). At the stop position of the wiper, the center of the wiper rubber floats about 10 mm so that it floats about 10 mm. Adhesion was made almost parallel to the direction of movement, with the thinner side as the tip. Materials such as foamed polyethylene can also be used as long as they have slipperiness, impact resilience, weather resistance and wear resistance. In addition, as a float (2), a natural sponge with repulsive elasticity is cut from a thin side with a length of 50 mm and a width of 50 mm to a thickness of 5 mm and a thick side with a thickness of 25 mm, and the outer circumference is covered with polyethylene having a thickness of 1 mm and a width of 50 mm. The same procedure was carried out for a material comparable to that shown in FIG. 7 which was covered and adhered. The float, which is made of wood with the same shape as a natural sponge and is bonded by covering the outer circumference with polyethylene with a thickness of 1 mm and a width of 50 mm, makes a collision noise when it collides with the impact-resistant PVC pipe VP13, which acts as a sliding pipe (1). Therefore, it was found that a material with high hardness is unsuitable and requires a material that can absorb impact. The present invention was implemented for all of the wiper on the driver's side, the wiper on the passenger's side, and the rear wiper. Confirmed when it rained. The color of the sliding pipe (1) and the float (2) should be black or dark so that it blends in with the color of the wiper arm and its neighbors. After confirming the passage of about 3 months, it was confirmed that there was no damage to the glass due to earth and sand when the wiper was operated, there was no dirt due to sticky dust, the tip of the wiper rubber was clean, and there was no problem with the function of the wiper. ..

The present invention automatically floats the wiper rubber from the windshield or rear glass at the wiper stop position to create a gap, thereby removing deterioration of the wiper rubber, damage to the glass due to earth and sand when the wiper operates, and dirt on the glass due to sticky dust. It is widely used by providing a new wiper floating device that prevents the wiper function and does not interfere with the wiper function.
