Description

  The present invention relates to an air wiper in an automobile in which compressed air is blown onto a front glass of an automobile to scatter rainwater on the glass surface.

In a conventional automobile wiper, a wiping member that rotates left and right on the glass surface removes rainwater from the front glass.
However, the rainwater removal function is sufficient, but the rotation of the wiping member is very obstructive for the driver, and the view may be interrupted instantaneously, which is not always preferable for safe driving. Removal technology development is eagerly desired.

  An object of the present invention is to provide an epoch-making automobile air wiper that sweeps the rain of the windshield by sweeping out the conventional drawbacks and blowing compressed air onto the windshield. Is.

  In order to achieve the above-mentioned object, the present invention blows compressed air onto the windshield of an automobile to scatter rainwater on the glass surface into the pressure of the air, and the nozzle of the compressed air moves from above the windshield to the front. It is set so as to be able to appear and disappear horizontally along the glass direction or along the inclination of the front glass, and the shape of the nozzle attached to the tip of the nozzle officer is bent into an L shape bent at a right angle or a shape slightly opened from this. The nozzle is detachably attached to the tip of the nozzle officer.

  In the present invention, since a plurality of nozzles move forward and backward from the top of the windshield of an automobile toward the windshield, and compressed air is blown against the windshield during advance, the compressed air is directed to the glass surface. The rain water on the front windshield is surely scattered, especially when the nozzles located on both sides and the nozzle located at the center operate alternately, i.e. when the nozzles on both sides move forward and squeeze out compressed air The central nozzle moves backward, and when the central nozzle moves forward, the nozzles on both sides move backward, and the nozzles on both sides and the central nozzle move alternately to blow the compressed air. Compressed air that reaches the corners of the glass can make the effect of splashing rainwater even more pronounced, and compressed air that is heated moderately by a heater installed in the vicinity of the insufflator of compressed air. This can also remove snow adhering to the front glass, and in combination with the above effects, it is possible to provide a vehicle wiper that does not obstruct the driver's view. The contribution is extremely large.

A specific configuration of the present invention will be described with reference to the drawings.
FIGS. 1 to 3 are views showing a case where the device of the present invention is installed in a passenger car. FIG. 1 shows a case where the device is installed in an existing passenger car, and FIG. 2 is integrated in the manufacturing process of the passenger car. In each case, a box part 1 is provided at the front part of the roof B of the passenger car A, and a mechanism part is incorporated in the box part 1.

  Thus, the nozzle member 2 bent in a U-shape is arranged at the center and on both sides, and each tip of the nozzle member 2 slightly protrudes from the tip of the box 1. The nozzle 3 is detachably screwed. The nozzle 3 is prepared in an L-shape that is bent at a right angle and a nozzle that is bent at an angle slightly opened from the right angle.

In the box 1 there is a rotating shaft 6.7 which is rotated by a respective motor 4.5, and each said nozzle member 3 is housed in a guide rail 8 which guides the guide rail 8. The rack 9 is installed on each nozzle unit 3 and the pinions 10 on one rotary shaft 6 of the rotary shaft 6.7 are engaged with the nozzle units 3 arranged on both sides. The pinion 11 of the other rotating shaft 7 is engaged with the rack 12 of the nozzle pawl 3 disposed in the center.
The gears 13.14 on the rotary shaft 6.7 are then connected to the shafts 4a. Gears 13a. 14a is engaged, and the nozzle can 3 is moved forward and backward by the rotation of the motor 4.5, and the nozzles 3 on both sides are moved forward and backward together as a result of the sensor. The nozzle 3 moves in the opposite direction to the nozzles 3 on both sides, that is, when the nozzles 3 on both sides move forward, the center nozzle 3 moves backward and when the nozzles 3 on both sides move backward, Nozzle officer 3 moves forward, and in either case, the compressed air is blown only when nozzle officer 3 moves forward.

Next, each of the nozzle officers 3 is in contact with an insufflator 16 communicating with the compressor 15, and the compressed air sent by the insufflator 16 is blown from the nozzle 3a of the nozzle officer 3 to the front glass of the automobile. It starts to scatter rainwater.
Each nozzle pipe 2 is connected to an air supply pipe 17 communicating with the compressor 16, and compressed air sent by the air supply pipe 17 blows from the nozzle 3 of the nozzle pipe 2 to the front glass of the automobile to scatter and remove rainwater. It becomes like this. In addition, there is a heater section 18 in the middle of the air supply pipe 17, and by blowing the compressed air heated by the heater section 18, it is possible to easily remove snow on the front glass. It becomes.

  4 and 5 are views when the device of the present invention is applied to an automobile such as a truck, a light van, etc., and the internal mechanism is exactly the same as described above, but the nozzle tube 2 is inclined by the angle of the front glass. In this case, the nozzle tube 2 is moved forward and backward in a slanting vertical direction, so that the box 1 is required to have a height necessary for the stroke of the nozzle tube 2. Will be. This device can also be implemented in passenger cars if the design of the passenger car is ignored. This device operates in a state where the nozzle tube 2 is close to the front glass, and the rainwater removing function becomes very remarkable.

  The present invention can be used not only for automobiles such as passenger cars and trucks but also as wipers for ships and the like.
