【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 shows a wiper 1 of a first embodiment of the present invention. The wiper 1 has a wiper arm 2 and a wiper blade 3. The wiper arm 2 has a rod-shaped stay 4 and arm pieces 5 and 6, and the staple 4 and the arm pieces 5 and 6 are connected by universal joint portions 7 and 8.

For the arm pieces 5, 6, and the stay 4, a material that is easily elastically deformed in the width direction, that is, the left-right direction in FIG. 1B, such as SUS plate or resin, is selected.

The arm piece 6 is fixed to a single suction disc 9 as a mounting means. The suction plate 9 has a base portion 10 which is attached to a glass (mirror) 15 as an object, and a shaft portion 11 which is provided substantially in the center of the base portion 10. ..

The cantilevered wiper arm 2 is elastically deformed with the shaft portion 11 as a fulcrum, and can be operated in a fan shape within a predetermined range, that is, can freely swing.

The wiper blade 3 is attached to the stay 4 of the wiper arm 2. The wiper blade 3 is formed by a rubber-like elastic body, and has a base portion 12 in which the stay 4 is embedded and a lip portion 13 having a substantially wedge-shaped cross section. The base portion 12 and the lip portion 13 are It is connected by a thinner neck portion 14.

Then, the surfaces A and B of the lip portion 13 of the wiper blade 3 are subjected to a non-adhesive treatment as a frictional resistance reducing means. This non-sticking treatment is for reducing the frictional resistance of the lip portion 13 against the glass 15. Specifically, in order to stabilize the wiper blade 3 by immersing it in a chlorine-based solvent that generates active chlorine gas, or by exposing the wiper blade 3 to a chlorine gas atmosphere to deposit chlorine on surfaces A and B. Then, heat treatment (for example, at 100 ° C. for about 1 hour) is performed to increase the surface hardness.

Further, a weight 16 as a starting means is attached to the free end side of the stay 4. The weight 16 is made of metal such as lead, and can be moved and stopped on the stay 4 along the axis in the direction of arrow D. It should be noted that if a screw is provided on the outer periphery of the stage having a circular cross section and a female screw is provided on the inner peripheral surface of the weight, it is easy to move and stop.

Next, the operation of the wiper 1 will be described. First, the wiper 1 is attached to the mirror 18 of the outside mirror (door type) 15 as shown by the solid line in FIG. The mounting state is such that the wiper arm 2 is substantially horizontal to the ground when the vehicle body is stopped.

During traveling, the vehicle body vibrates due to the unevenness of the road surface, and at the same time, the outside mirror 15 also vibrates vertically. Then, an operating force, that is, an inertial force is generated in the weight 16, and the wiper arm 2 is elastically deformed by the suction plate 9 as a fulcrum by the inertial force, and a predetermined position is vertically moved from a reference position shown by a solid line in FIG. It swings like a pendulum in amplitude, that is, in the range E of the alternate long and short dash line. As a result, the wiper blade 3 wipes the mirror 17 in the range E to remove water droplets and secure a rear view.

As described above, in the present invention, the natural power source called the vibration of the vehicle body is converted into the inertial force of the weight 16, and the wiper arm 2 is swung by the inertial force. Therefore, the structure is simple and the manufacturing cost can be suppressed. The outside mirror may be a front wing type.

If the inertial force is adjusted by moving the weight 16 along the stay 4 and changing the relative position to the stay 4, the swing range E and the cycle of the wiper arm 2 can be changed. In this case, it goes without saying that the wiper arm 2 is adjusted so as not to come into contact with the frame 19 of the outside mirror 15.

Further, since the wiper arm 2 can freely change the angle and distance with respect to the glass 15 by the joint portions 7 and 8, the wiper blade 3 can be brought into contact with the glass 15 at an appropriate pressure.

Further, since the surfaces A and B of the wiper blade 3 are non-adhesive treated, the friction resistance with the glass 15 is small, the glass 15 is not adhered, and a smooth wiping property can be obtained.

If the shaft portion 11 is configured to be easily twisted and deformed, the swing of the wiper arm 2 becomes smoother, and the swing of the wiper arm 2 is transmitted to the suction plate 9 via the shaft portion 11. It is possible to prevent the suction plate 9 from falling off the glass 15 without any trouble. Needless to say, the suction cup 9 can be removed from the glass 15 in fine weather.

FIG. 2B shows a second embodiment. In this embodiment, a plurality of suction discs 9, that is, two suction discs 9 are provided, and the suction discs 9 are connected by a fixing rod-like stay 20. The upper suction plate 9 is slidably attached to the stay 20. The lower suction plate 9 is fixed to the stay 20.

According to this structure, the attaching force to the wiper 1 becomes strong, and the function of preventing the falling is improved. Other configurations, operations, and effects are similar to those of the first embodiment.

FIG. 2C shows a third embodiment. That is, this is an example in which the wiper 1 of the present invention is attached not only to the outside mirror 17 but also to the outer surface of the door glass 21. When the outside mirror 17 is a door-mounted type, even if the glass 15 of the outside mirror 17 is wiped, the rear side cannot be confirmed even if the door glass 21 is fogged. Therefore, the wiper 1 for the door glass 21 is attached at a position where the eyes of the driver are connected to the outside mirror 17.

The configuration of the wiper 1 is similar to that of the first and second embodiments. According to this structure, the rainwater on the door glass 21 and the rainwater on the outside mirror 17 can be wiped at the same time, and the rear can be easily confirmed.

[0038]

[Effect of the device]

 Since the present invention is configured as described above, the natural power source called the vibration of the object is converted into the operating force by the starting means, and the wiper arm is operated by the operating force. Therefore, the structure is simple and the manufacturing cost can be reduced.

Further, the operating amount of the wiper arm can be changed by adjusting the operating force of the starting means.

If a plurality of attaching means are provided, the attaching force to the object is increased, and the function of preventing the object from falling off is improved.

Further, the frictional resistance between the object and the wiper blade is reduced, smooth operation is possible without sticking and catching, and the wiping property is improved.
