DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiper blade connecting device for connecting a wiper arm and a wiper blade, and more particularly, to a wiper blade connecting device which can be housed in a blade metal frame, makes a holder rotatable, and The present invention relates to a wiper blade connector that can prevent rattling of a wiper blade or deformation or breakage of a clip frame constituting a wiper blade connector even when wiper arms having different arm thicknesses are used.

[0002]

2. Description of the Related Art FIGS. 14 and 15 show a state in which a wiper arm is attached to a conventional wiper blade connector. The wiper blade connector 1 includes a substantially U-shaped clip frame 2.
And a holder 3 fixed between the left and right side walls of the clip frame 2 and having a curved left end, and a clip lid 4 rotatably fixed to the clip frame 2. I have. Then, the substantially U-shaped portion of the wiper arm 6 whose tip is bent into a substantially U shape is hooked and attached to the curved portion of the holder 3 of the wiper blade connector 1, and then the clip lid 4 is clipped to the clip frame. 2, the wiper blade connector 1 and the wiper arm 6 are connected.

As shown in FIGS. 14 and 15, in the conventional wiper blade connector 1, the movable range of the wiper arm 6 is limited because the holder 3 is fixed to the wiper blade connector 1. (See Japanese Utility Model Publication No. 3-49081). When the wiper arm 6 and the wiper blade are connected by using such a wiper blade connector 1, when the wiper is set up for wiping the windshield of an automobile, etc., depending on how the wiper arm and the wiper blade are held, the wiper blade connection may be made. As a result of excessive force being applied near the clip frame fixing holes 211a and 211b of the tool 1, the tool 1 may be bent at this portion, causing damage to the wiper blade connector 1.
As a solution to such a problem, for example, a wiper blade connector in which a holder is fixed by a pin, not a fixed type, and is movable has been proposed (Japanese Utility Model Laid-Open No. 6-7).
No. 5931).

[0004] However, the wiper blade connector described in Japanese Utility Model Laid-Open No. 6-75931 has a holder and a clip lid directly attached to the blade metal frame. However, there is a problem that these holders and clip lids may easily come off from the wiper blade connector. In order to solve such a problem, it is desirable to prevent the deformation of the clip frame constituting the wiper blade connector by forming the wiper blade connector in a blade metal frame. The fact is that a wiper blade connector that can be housed inside and has a holder portion rotatably fixed has not been developed.

In recent years, the thickness of the wiper arm differs depending on the manufacturer. When a thick wiper arm is attached to a wiper blade connector based on a thin arm, the clip lid cannot be fitted, and the clip frame may be deformed or damaged. . On the other hand, when the wiper arm with a thin arm is attached to the wiper blade connector based on the thicker arm, the pressure of the wiper arm fitted to the holder is incomplete,
Play may occur between the wiper arm and the wiper blade. When such rattling occurs, there is a problem that a sound is generated when the windshield is wiped by the wiper blade, and the function of the wiper blade to wipe the windshield cannot be sufficiently exhibited.

Further, when the wiper blade is used as a snow blade in a cold region, if water is accumulated in the wiper blade connector, especially the movable part, it causes freezing, which makes it difficult to exhibit the function as a snow blade. There is a problem that becomes.

a, 44b to prevent breakage due to excessive deformation and to prevent the ceiling plate portion 4 constituting the clip lid 4 from being damaged.
Since the ceiling plate portion 2 itself has elasticity, the ceiling plate portion 42 itself slightly bends, so that deformation and breakage of the clip frame 2 can be prevented, and the clip frame 2 is fitted into the blade metal frame 51 to prevent deformation of the clip frame 2. Even if it is prevented, clip lid 4
Can be easily fitted to the clip frame 2. Therefore, even if the wiper arm 6 is rotated in this state and the windshield or the like of the vehicle is wiped with the wiper blade 5, no noise due to rattling occurs.
A situation in which the wiper blade 5 hardly performs its original function can be avoided.

Further, since the holder 3 to which the wiper arm 6 is hooked and attached is rotatable, the connection of the wiper blade can be made even more depending on how the wiper arm and the wiper blade are held than the conventional fixed type. Excessive force can be prevented from being applied to the tool 1, especially the vicinity of the clip frame fixing holes 211a and 211b, and as a result, the wiper blade connector 1 can be prevented from being damaged. Further, since the holder body 31 has the lower protrusion 312, the holder body 31 does not fall down excessively, so that the wiper arm 6 can be easily fitted to the holder 3, and the curved surface Because it has the part 313,

Since the holder main body 31 and the left and right side walls thereof are provided with the drainage slits 311, water derived from rain and snow can pass through the slits 24 a, 24 a.
It moves toward the blade metal frame 51 via the second notch 25a and the second notch 25b, and is finally discharged from the lower groove 512 of the blade metal frame 51. Further, since the width of the ceiling plate portion 42 of the clip lid 4 is the same as the width of the wiper blade connector 1, by covering the wiper blade connector 1 from above, the upper portion of the clip lid 4 is separated from the upper portion. A gap can be prevented from being formed between the wiper blade connector 1 and the wiper blade connector 1. Therefore, it is possible to prevent water derived from rain and snow from entering the gap. Further, since the upper surface shape of the ceiling plate portion 42 constituting the clip lid 4 is mirror-finished and has a curved surface,
Rain and snow can be prevented from adhering to the wiper blade connector 1 as compared with a horizontal shape or a rough surface. As described above, since the water does not accumulate on the wiper blade connector 1, especially the movable portion thereof, it is possible to prevent freezing even when used in cold regions, and as a result, it is suitable as a snow blade especially in cold regions. Can be used.

In the wiper blade connector 1 of the second embodiment, as shown in FIG.
211b, the clip frame fixing hole opening ports 214a,
Holder shaft locking projections 215a and 215b projecting inward in a substantially trapezoidal shape are provided at a portion near 14b. For this reason, when the holder 3 held horizontally between the clip frame side walls 21a and 21b is rotated and raised as shown in FIG.
2 abuts on the holder shaft locking projections 215a and 215b, the holder 3 cannot be rotated more than the predetermined rotation angle α. Accordingly, when the wiper arm is mounted on the holder 3, the holder 3 is prevented from rotating too much and the rotation angle α is prevented from exceeding a predetermined range, and the wiper arm contacts the clip lid and breaks it.
