Description

The present invention relates to a wiper for vehicles.

Patent Literature 1 discloses a wiper for a vehicle. This vehicle wiper includes a wiper arm, a wiper blade having a lever connected to the tip of the wiper arm, and a clip as a connecting member that rotatably connects the lever to the wiper arm.

The lever has a pair of side walls, a connecting wall connecting one ends of the side walls, and an opening into which the clip is inserted.
A shaft extending between the side walls and a pair of restricting projections protruding from the side walls so as to face each other are formed in a portion of the pair of side walls forming the opening.

The clip has a pair of side walls and a connecting portion connecting the side walls. The clip has a shaft hole penetrating through the pair of side walls and the connecting portion, and a slit opening a part of the peripheral wall of the shaft hole.

The clip is inserted inside the lever through the opening. The clip is rotatably supported with respect to the lever by fitting the shaft of the lever into the shaft hole of the clip through the slit.
Limiting grooves are formed on the outer side surfaces of both side walls of the clip to limit the relative movement of the limiting protrusions within a predetermined angular range by coming into contact with the limiting protrusions of the lever. The limiting groove has a groove opening that guides the limiting projection into the limiting groove when the clip is inserted through the opening of the lever.

The restricting projection and restricting groove are provided at a position near the proximal end of the wiper arm with respect to the shaft and shaft hole that are the centers of relative rotation of the lever and clip.
Further, Patent Document 2 discloses a wiper for a vehicle. The lever of the wiper blade of this vehicle wiper has a fin surface that is inclined so that the outer surface of the side wall on the front side in the vehicle front-rear direction is located on the front side as it approaches the wiping surface. The blade rubber of the wiper blade is pressed against the wiping surface by the fin surface receiving the running wind when the vehicle is running.

By the way, in such a vehicle wiper, it is desired to share the wiper blade and the connecting member between the right-hand drive vehicle and the left-hand drive vehicle. However, the directions in which the wiper arms extend with respect to the wiper blades are opposite to each other between the right-hand drive vehicle and the left-hand drive vehicle. Therefore, the wiper blade cannot be used as it is. Therefore, for example, when attempting to assemble a wiper arm for a left-hand drive vehicle to a wiper blade for a right-hand drive vehicle, it is necessary to turn the wiper blade back and forth 180 degrees from its normal posture. That is, it is necessary to direct the fin surface of the side wall of the lever rearward in the longitudinal direction of the vehicle. In this case, the fin surface cannot receive running wind.

On the other hand, it is conceivable to leave the wiper blade in the normal position and assemble the clip in a position that is reversed back and forth with respect to the lever. However, in that case, since the limiting groove is located on the opposite side of the shaft from the limiting projection, the limiting projection cannot escape, and the clip cannot be assembled.

A wiper for a vehicle for solving the above-mentioned problems includes a wiper arm, a wiper blade having a lever connected to a tip portion of the wiper arm, and a connecting member that rotatably connects the lever to the wiper arm. In the vehicle wiper provided, the lever comprises a housing hole that continues to an opening into which the connecting member is inserted and that houses the connecting member, and a The connecting member includes a pair of side walls extending in the extending direction and a shaft portion that spans between the pair of side walls. The wiper includes a connecting portion that connects the side walls and is connected to the tip portion of the wiper arm, a shaft hole that rotatably supports the shaft portion, and a slit that opens a part of the peripheral wall of the shaft hole. At least one of the pair of side walls has a first contact portion, and at least the other of the pair of side walls is formed with the first contact portion across the shaft hole in the extending direction. has a second contact portion provided on the opposite side, and the inner surface of at least one of the pair of side wall portions is in contact with the first contact portion so as to be centered on the shaft portion. A first restricting protrusion is provided for restricting the rotation of the connecting member in the first direction, and at least the other inner surface of the pair of side wall portions is in contact with the second contact portion so that the A second regulating projection is provided for regulating rotation of the connecting member about the shaft in a second direction opposite to the first direction, and the first regulating projection and the second regulating projection are provided. The protruding portion is provided on the side opposite to the opening with respect to the shaft portion in the height direction of the lever and sandwiching the shaft portion in the extending direction.

According to this configuration, when the connecting member rotates about the shaft of the lever in the first direction, the first contact portion of the clip contacts the first restricting projection of the lever, thereby causing the first contact portion of the connecting member to rotate. Rotation in the direction is restricted. Further, when the connecting member rotates in the second direction about the shaft portion of the lever, the second contact portion of the clip contacts the second restricting protrusion of the lever, thereby rotating the connecting member in the second direction. movement is restricted.

According to the above configuration, the first restricting protrusion and the second restricting protrusion are provided on the side opposite to the opening with respect to the shaft in the height direction of the lever. This makes it difficult for the first restricting protrusion and the second restricting protrusion to interfere with the linking member when the linking member is inserted into the opening of the lever for assembly. Further, even when the connecting member is reversed so that the position of the first contact portion and the position of the second contact portion are reversed, the connecting member can be assembled by inserting it into the opening of the lever. can.

Furthermore, in the posture in which the connecting member is inverted as described above, when the connecting member rotates in the first direction about the shaft of the lever, the second contact portion of the clip engages the first restricting protrusion of the lever. The contact restricts the rotation of the connecting member in the first direction. Further, when the connecting member rotates in the second direction about the shaft portion of the lever, the first contact portion of the clip contacts the second restricting protrusion of the lever, thereby rotating the connecting member in the second direction. movement is restricted.

Therefore, it is possible to share the wiper blade and the connecting member between the right-hand drive vehicle and the left-hand drive vehicle.
In the above vehicle wiper, the first contact portion and the second contact portion are provided on both of the pair of side walls, and the first restricting protrusion and the second restricting protrusion are provided on the pair of side walls. is preferably provided on both of the side wall portions of the

According to this configuration, it is possible to more reliably restrict the rotation of the connecting member about the shaft of the lever.
Also, the load acting on each contact portion and each restricting protrusion can be suppressed.

In the above vehicle wiper, it is preferable that the lever is made of resin, the pair of first restricting protrusions are opposed to each other, and the facing surfaces of the first restricting protrusions are fractured surfaces. .

According to this configuration, in the configuration in which the first restricting protrusions are provided on both sides of the pair of side walls, the pair of first restricting protrusions connected by the runner is resin-molded, and the runner portion is formed. By breaking and removing, a lever having a pair of first restricting projections can be formed. Therefore, the lever can be easily formed. In addition, unlike the case where the gate is set on other parts of the lever, the design of the lever can be easily improved.

In the above vehicle wiper, it is preferable that the first restricting protrusion and the second restricting protrusion have a shape orthogonal to the extending direction and symmetrical with respect to a virtual plane including the center of the shaft. .

According to this configuration, regardless of the mounting posture of the connecting member with respect to the lever, it is possible to make the regulation mode of the rotation of the connecting member about the shaft portion of the lever the same.

According to the present invention, the wiper blade and the connecting member can be shared between the right-hand drive vehicle and the left-hand drive vehicle.
