Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiper blade, and more particularly to a wiper blade having an improved wiping property.

[0002]

[Prior Art and Problems to be Solved]

 Generally, a wiper blade used for a reciprocating wiper for wiping off rainwater or the like adhering to a window glass of an automobile or the like when traveling in the rain is known as shown in FIG. 4, and this wiper blade is known. The reference numeral 21 includes a lip portion 23 having a flat end portion 23a, an attachment portion 22 attached to a blade fitting of a wiper, and a neck portion 24 connecting the lip portion 23 and the attachment portion 22. There is.

Then, as shown in FIG. 5, the wiper blade 21 is attached to a blade metal fitting 25 of the wiper, and the wiper is actuated so that the tip portion 23a of the lip portion 23 of the wiper blade 21 is attached to an automobile or the like. By slidingly contacting the window glass 26 and reciprocating on the window glass 26, rainwater and the like adhering to the window glass 26 can be wiped off when traveling in the rain to maintain a good field of view.

However, in the conventional wiper blade 21 configured as described above, if the wiper blade 21 cannot follow the reciprocating movement of the wiper, the wiper blade 21 does not operate smoothly, and as shown in FIG. As a result, the sealing property with the window glass 26 deteriorates, and rainwater cannot be completely wiped off, which may hinder the visibility. As shown in FIG. 7, the so-called judder phenomenon of the wiper blade 21 The tip portion 23a of the lip portion 23 bounces off, and the unwiped streak 27 is generated in the radial direction of the window glass 26 on which the wiper blade 21 rotates, which deteriorates the visibility of the window glass 26. It was

The present invention solves the above-mentioned problems of the conventional one, and an object thereof is to provide a wiper blade that smoothly follows the movement of the wiper and has an improved wipeability. Is.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is designed to remove rainwater, etc. adhered to the window glass when the wiper reciprocally rotates by slidingly contacting the attachment part attached to the blade metal fitting of the wiper and the surface of the window glass. A wiper blade comprising a wiped lip portion and a neck portion connecting the attachment portion and the lip portion, wherein the attachment portion is swingably attached to the blade fitting. Is.

[0007]

[Action]

 According to the present invention, by adopting the above means, when the wiper is turned over, the mounting portion of the wiper blade swings, and the wiper blade can be turned over smoothly, so that the followability is improved. As a result, unlike the conventional method, the tip of the lip is not subjected to excessive stress, blurring or judder phenomenon does not occur, the wiper blade's wiping performance is improved, and the view of the window glass may be obstructed. Absent.

[0008]

【Example】

 An embodiment of the present invention shown in the drawings will be described below. FIG. 1 shows an embodiment of a wiper blade according to the present invention. This wiper blade 1 has a plate-like portion 2a provided with a substantially cylindrical top portion 2b extending in the long side direction substantially on the center line. The attachment portion 2 and the lip portion 3 are connected to each other and the lip portion 3 in which the lip 3a is formed on the left and right sides and the flat plate-shaped tip portion 3b is formed under the lip 3a. It is composed of a flat neck portion 4.

In addition, as shown in FIG. 2, the blade fitting 5 to which the wiper blade 1 is attached has a substantially cylindrical shape into which a top portion 2 b of the attachment portion 2 of the wiper blade 1 is inserted, and a space 7 whose lower portion is open. Are formed in the longitudinal direction.

Then, when the top portion 2b of the mounting portion 2 of the wiper blade 1 is inserted into the space 7 provided in the blade fitting 5, the wiper blade 1 swings about the top portion 2b. ing.

When the wiper blade 1 configured as described above is attached to the blade fitting 5 to bring the tip 3b of the lip 3 into contact with the window glass 6 of an automobile or the like, and when the wiper is operated, As shown in Fig. 5, the front end 3b of the lip portion 3 of the wiper blade 1 is slidably in contact with the window glass 6, and the tip 3b is bent rearward in the traveling direction, and reciprocally rotates to cause rain. It is possible to maintain good visibility by wiping off rainwater or the like adhering to the window glass 6 when traveling.

The wiper blade 1 can swing about the top 2b by slidingly contacting the top 2b of the mounting portion 2 with the inner peripheral surface of the space 7 formed in the blade fitting 5. Therefore, it is possible to give the wiper a degree of freedom when reciprocally rotating.

Therefore, when the wiper is reciprocally rotated, the wiper blade 1 can be smoothly inverted and the followability is improved, and the judder phenomenon does not occur unlike the conventional case, and the window glass 6 There is no fear of obstructing the field of view.

In the embodiment, the mounting portion 2 of the wiper blade 1 is formed to have a circular cross section, the void 7 of the blade fitting 5 is formed to be circular, and the wiper blade 1 is swung with respect to the blade fitting 5. However, the shape of the mounting portion 2 of the wiper blade 1 may be any shape as long as it can swing with respect to the blade fitting 5.

[0015]

[Effect of device]

 In this invention, as described above, since the wiper blade can swing with respect to the blade fitting, when the wiper reciprocally rotates, the wiper blade can be smoothly inverted and the followability is improved. The judder phenomenon does not occur unlike in the past. Therefore, the wiping property of the wiper blade is improved, and there is an effect that there is no fear of obstructing the field of view of the window glass.
