Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wiper mounted on an automobile.

[0002]

2. Description of the Related Art The above-mentioned wiper is equipped with a wiper blade at the tip of an oscillating link, and the wiper blade therein is for contacting with a glass surface to wipe off water droplets, snow, dirt, etc. adhering to the glass surface. It is composed of a blade rubber and a metal blade holding fitting for holding the blade rubber. The blade holding fitting includes a rubber holding member.

This wiper is generally provided on the windshield, but it may also be provided on the rear glass, as well as on headlights and door mirrors.

By the way, in cold seasons such as winter, for example, rainwater, snow, or frost falling on the glass surface of a parked car may freeze, and the blade rubber may freeze on the glass surface. If you forcibly drive the wiper, you will damage the motor, and if you forcibly peel off the blade rubber, the blade rubber will be damaged.

Even if the blade rubber is peeled off from the glass surface, granular ice is present on the glass surface in a pear-like texture and the visibility is deteriorated. Therefore, the wiper is further driven. However, since the blade rubber only disturbs the icy surface and makes it cloudy, it rather deteriorates the visibility, so the driver first rides and starts the engine, then heats the inner surface of the glass surface. For the windshield and rear glass with a heater, supply the hot air for the heater, and energize the heater wired inside the glass or the heater stretched around the glass to melt the ice that has frozen on the glass surface. I try to remove the ice with a wiper.

[0006]

However, it is extremely inefficient to thaw the ice frozen between the glass surface and the blade rubber or the ice frozen on the glass surface through the glass,
The time loss for that is large, and there is a problem in that the waiting time before the start of operation is long. In particular, with regard to headlights and general door mirrors, it was inevitable to let the ice melt.

When the wiper blade is covered with snow, it narrows the field of view, so it is scraped off by hand, but it is very difficult to scrape off the ice frozen on the blade rubber by hand. It ’s difficult, and
If you encounter snowfall while driving, the conventional general blade rubber often does not remove the snow completely, resulting in poor visibility, and there is no way to remove the snow accumulated on the wiper blade. In order to do so, I was forced to stop.

The present invention has been made in view of the above circumstances, and an object thereof is to efficiently solve ice frozen on a glass surface, particularly ice frozen between the glass surface and the blade rubber. In addition to being able to remove the snow, it is easy to secure the visibility during snowfall even while driving, and it is possible to actively remove the snow accumulated on the wiper blade and to provide a wiper for automobiles. .

[0009]

That is, a wiper for an automobile according to the present invention is characterized in that a blade rubber of a wiper blade provided at a tip end of a swing link is internally provided with a heater (claim 1). .

According to such a wiper, the blade rubber heats the internal heater to apply heat energy to the blade rubber, so that even if the blade rubber freezes on the glass surface, The ice between the blade rubber and the blade rubber can be efficiently thawed, and the blade rubber can be easily and quickly peeled off from the glass surface.

In addition to driving the wiper in a state where the heater is heated, hot air is supplied to the inner surface of the glass surface, or in the case of a rear glass or the like, if the heater is heated, the glass is heated. The ice that has frozen on the surface is not only thawed through the glass, but also directly receives thermal energy from the heater from the outside and is efficiently thawed into a sherbet shape in a short time. The waiting time can be shortened.

On the other hand, it is possible to easily remove even the ice frozen on the blade rubber itself, and this is the same for the wiper equipped in the headlight, the door mirror, etc. When the rubber surface is provided on the glass surface side and the rubber holding member side with respect to the rubber (Claim 2), thermal energy is positively applied to the rubber holding member, so that the ice frozen on the rubber holding member Can be easily removed.

Even when snow is encountered during traveling, the blade rubber is warmed by the heater, so it is easy to thaw the snow on the glass surface to secure the field of view, and the blade rubber and the rubber holding member are lowered. Since such snow also melts and flows, it is possible to effectively prevent the accumulation of snow on the wiper blade and the rubber holding member and ensure a good field of view.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show two wipers 1, 1 installed on the windshield side of an automobile,
As shown in FIG. 3, the wiper 1 is provided with a wiper blade 3 at the tip of a swing link 2 which is reciprocally swung by a motor (not shown).

As shown in FIG. 4, the wiper blade 3 is in contact with the glass surface S, and is a blade rubber for wiping off water drops, snow, dirt, etc. adhering to the glass surface S as the swing link 2 swings. 4 and metal blade holder 5
And these are made into a unit, and the entire unit is replaceably attached to the tip of the swing link 2.

The blade rubber 4 has a glass surface S.
Tip lip 4 that can be easily deformed flexibly in contact with
a and a T-shaped base portion 4b, while the blade holding metal fitting 5 includes a rubber holding member 6 for fitting and holding the T-shaped base portion 4b of the blade rubber 4.

The wiper 1 having the above-described structure is merely an example of a conventionally known one, and in the present invention, as shown in FIG. 4, the blade rubber 4 is connected to a battery 7 mounted on an automobile to generate heat. Waterproof type heater 8
The feature is that the interior is decorated.

The electric circuit for the two heaters 8, 8 is shown in FIG. In FIG. 1, reference numeral 9 in the drawing is a relay box, which incorporates a fuse 10 connected to the battery 7.

An on / off switch 11 is connected to the fuse 10 and is provided at a position (a lower portion of the handle column in this embodiment) that is easily operated by a driver sitting in the driver's seat.

A lead wire 12 for connecting the two heaters 8, 8 in series is connected between the switch 11 and the body ground, and the whole unit can be easily replaced. A waterproof connector 13 is provided near the tip of the swing link 2.
The lead wire 12a leading to the connector 13 is of a two-core type.

According to the wiper 1 having the heater 8 described above, the blade rubber 4 is frozen on the glass surface S or the glass surface S due to snowfall or frost in the cold season such as winter. When the ice freezes, the switch 11 is operated to heat the heater 8 so that the ice between the glass surface S and the blade rubber 4 can be efficiently melted, and the blade rubber against the glass surface S can be effectively melted. Freezing of 4 is easily and quickly resolved.

Then, with the heater 8 being heated,
In addition to driving the wiper 1, if hot air for heating is supplied to the inner side of the glass surface, or in the case of a rear glass or the like, the heater is heated, the glass surface S
Since the ice that has frozen to the ice melts efficiently in a short time,
This can be easily removed by a wiper, and even the ice frozen on the blade rubber 4 itself can be easily removed.

Even if a snowfall is encountered during traveling, since the blade rubber 4 is warmed by the heater 8, it is easy to thaw the snow on the glass surface S to secure the field of view. Since the snow falling on the holding member 6 is also melted and flows, the snow can be effectively prevented from being accumulated on the wiper blade 3 and a good field of view can be secured.

In the above embodiment, the blade rubber 4
However, it is also possible to provide a plurality of heaters 8, and at this time, as shown in FIG. 5, two heaters 8, 8 are provided for the blade rubber 4. If the glass surface S side and the rubber holding member 6 side, that is, the lip 4a side and the T-shaped base portion 4b side are provided, the thermal energy is positively applied to the rubber holding member 6 as well. There is an advantage that even the ice frozen on the rubber holding member 6 can be easily removed.

[0025]

As described above, according to the present invention,
Even if the blade rubber freezes on the glass surface, it is possible to efficiently dissolve the ice between the glass surface and the blade rubber by adopting a unique configuration in which the heater is installed inside the blade rubber of the wiper, and the blade The rubber can be easily peeled off from the glass surface in a short time, and even ice frozen on the glass surface can be efficiently melted in a short time.

Further, the ice frozen on the blade rubber itself can be easily removed, and this is the same for the wipers equipped in the headlights, door mirrors, etc. Even if you encounter snowfall in the area, since the blade rubber is heated by the heater, it is easy to thaw the snow on the glass surface and secure visibility, and the snow that falls on the blade rubber and the rubber holding member can also be thawed. Since it flows, snow accumulation on the wiper blade is effectively prevented, and a good field of view can be secured.

In particular, if heaters are provided on the glass surface side and the rubber holding member side of the blade rubber, thermal energy is positively applied to the rubber holding member, so that the rubber holding member freezes. You can easily remove even ice.
