DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a support member and a supported member having a pivot formed on one side and a pivot hole formed on the other side, and the support member is supported by the pivot entering the pivot hole. The present invention relates to a support structure of a member for rotatably supporting the member.

[0002]

2. Description of the Related Art For example, there is a wiper blade for a vehicle wiper in which a second yoke is supported by a first yoke and connected in a so-called tongue manner. As a structure in which the first yoke of the wiper blade rotatably supports the second yoke, for example, a pivot hole is provided in the first yoke made of metal and the second yoke made of metal, and a pivot hole is formed in the pivot hole. By entering metal rivets,
There is a structure in which a first yoke supports a second yoke (hereinafter, referred to as a first yoke).
"Riveting method").

In Japanese Patent No. 2671955, a pivot hole is provided in a first yoke made of metal and a second yoke made of metal. Furthermore, a resin joint body is interposed between the first yoke and the second yoke,
A pivot is formed in the joint body. Here, there is a structure in which the first yoke supports the second yoke by the pivot of the joint body entering the pivot hole of the first yoke and the pivot hole of the second yoke (hereinafter, referred to as "pivot body method"). .

However, in the rivet method, since the first yoke, the second yoke, and the rivet are all made of metal, the first yoke, the second yoke, and the rivet are easily corroded and have low durability. Furthermore, when the windshield glass is wiped by operating the vehicle wiper, the load tends to concentrate on the pivot hole and the rivet, so that the pivot hole and the rivet are easily worn and the durability is low. Also, when the pivot hole and the rivet are worn, a gap is generated between the pivot hole and the rivet, so that when the vehicle wiper is operated, the peripheral wall of the pivot hole and the rivet come into contact with each other, increasing noise. I will.

On the other hand, in the pivot body method, since the first yoke and the second yoke are made of metal, the first yoke and the second yoke
The yoke is easily corroded and has low durability. Further, when the windshield glass is wiped by operating the vehicle wiper, the pivots and the pivot holes are easily worn and the durability is low similarly to the rivet method. Therefore, the noise when the vehicle wiper operates is increased. Further, the first yoke and the second yoke are made of metal, and the pivot of the joint body is made of resin. Therefore, when a slightly excessive bending stress acts on the second yoke, the pivot is particularly worn or damaged. easy.

Further, since the joint body is interposed between the first yoke and the second yoke, the number of parts increases, and the cost increases.

In particular, when the first yoke and the second yoke (including the pivot and the pivot hole) are made of resin, it is possible to prevent wear and damage of the pivot and the pivot hole when the vehicle wiper operates. Required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] FIG.
A main part of a vehicle wiper 10 according to a first embodiment to which a member supporting structure of the present invention is applied is shown in a front view, and FIGS. 2 and 3 show a vehicle wiper 10. Are shown in a sectional view. FIG. 4 is a front view showing the entire configuration of the vehicle wiper 10.

The vehicle wiper 10 according to the first embodiment
Is for wiping the windshield glass, and the windshield glass is curved.

The wiper blade 1 of the vehicle wiper 10
2 comprises a first yoke 24 as a support member,
The first yoke 24 is made of resin. First yoke 24
Is rotatably supported by a wiper arm 26 at the center in the longitudinal direction, and the wiper arm 26 applies an arm pressure to the wiper blade 12.

The cross section of the first yoke 24 is substantially U-shaped, and a top surface 28 as a second contact portion is formed near both ends in the longitudinal direction of the lower top surface. This top surface 28
Is a substantially arcuate curved surface protruding downward, and the curvature of this curved surface is determined by the magnitude of the rotation of a second yoke 14 described later with respect to the first yoke 24 when the wiper blade 12 wipes the windshield glass ( (Curvature of windshield glass).

In the vicinity of both ends in the longitudinal direction of the inner side surface of the first yoke 24, side surfaces 30 are formed as fourth contact portions. A pivot hole 32 is formed near the side surface 30, and the pivot hole 32 is formed in an elliptical shape curved along a substantially arc-shaped curved surface of the top surface 28 of the first yoke 24.

Immediately below the first yoke 24, a plurality of (two in this embodiment) second yokes 14 as supported members are provided.
Are connected. The second yoke 14 includes a first yoke 24
It is made of resin as well.

The cross section of the second yoke 14 is substantially U-shaped, and a columnar pivot 20 is formed on the side surface at the center in the longitudinal direction.
Are formed. This pivot 20 is the second yoke 14
, And the diameter of the pivot 20 is smaller than the width of the pivot hole 32 of the first yoke 24. As a result, the pivot 20 enters the pivot hole 32 of the first yoke 24 so that the first yoke 2
4 rotatably supports the second yoke 14, and allows the pivot 20 to move in the width direction and the longitudinal direction of the pivot hole 32.

A top surface 16 as a first contact portion is formed at the center of the upper top surface of the second yoke 14 in the longitudinal direction, corresponding to the top surface 28 of the first yoke 24. Here, the distance from the top surface 16 of the second yoke 14 to the side surface of the pivot 20 (distance B in FIG. 1) is the distance from the top surface 28 of the first yoke 24 to the peripheral wall of the pivot hole 32 (distance in FIG. 1). A) It is longer. For this reason, as shown in FIGS. 1 and 2, in a state where the pressing force acts on the second yoke 14 in the direction perpendicular to the axis of the pivot 20 (the direction of the arrow P in FIG. 1) and the turning force acts around the axis of the pivot 20. In addition, the pressing force and the rotating power are moved along the elliptical pivot hole 32 in which the top surface 16 of the second yoke 14 and the top surface 28 of the first yoke 24 are in contact with each other and the pivot 20 is curved. While rotating, the second yoke 14 rotates along the substantially arcuate curved surface in the direction of arrow S in FIG. 1 to receive the second yoke 14, whereby the first yoke 24 is kept in a state where the pivot 20 does not contact the peripheral wall of the pivot hole 32.
Are adapted to support the second yoke 14.

A side surface 18 as a third contact portion is formed at the center of the outer side surface of the second yoke 14 in the longitudinal direction, corresponding to the side surface 30 of the first yoke 24. Here, the axial direction of the pivot 20 is attached to the second yoke 14 (arrow Q1 in FIG. 2).
In the state where the pressing force acts in the direction of arrow Q2), the pressing force is applied to the side surface 1 of the second yoke 14 as shown in FIG.
The first yoke 24 supports the second yoke 14 in a state where the pivot 20 is not in contact with the peripheral wall of the pivot hole 32 by the contact between the side 8 and the side surface 30 of the first yoke 24. ing.

The second yoke 14 supports the blade rubber 22 at both ends in the longitudinal direction.

Next, the operation of the present embodiment will be described.

In the vehicle wiper 10 having the above configuration,
In a state where the wiper blade 12 is separated from the windshield glass, no arm pressure acts on the wiper blade 12, so that no pressing force in the direction of the first yoke 24 acts on the second yoke 14. In such a state, FIG.
As shown in FIG. 5, the pivot 20 of the second yoke 14 abuts on the peripheral wall of the pivot hole 32 of the first yoke 24, so that the first yoke 24 supports the second yoke 14, so that the second yoke 14 The first yoke 24 can be prevented from falling off.

When the vehicle wiper 10 is stopped (when the wiper blade 12 is in contact with the windshield glass), arm pressure acts on the wiper blade 12, so that the pivot 20 is perpendicular to the axis of the pivot 20 with respect to the second yoke 14 (see FIG. 1 (in the direction of arrow P). In such a state, as shown in FIGS. 1 and 2, the pressing force is received when the top surface 16 of the second yoke 14 abuts on the top surface 28 of the first yoke 24. Thereby, the first yoke 24 supports the second yoke 14 in a state where the pivot 20 does not contact the peripheral wall of the pivot hole 32. Therefore, the load is distributed to the top surface 28 of the first yoke 24 and the top surface 16 of the second yoke 14, and the pivot 20 and the pivot hole 32 are not loaded.

In the operating state of the vehicle wiper 10, a pressing force acts on the second yoke 14 in a direction perpendicular to the axis of the pivot 20 (the direction of the arrow P in FIG. 1), and the windshield glass is curved. A rotating force acts on the second yoke 14 around the axis of the pivot 20. In such a state, as shown in FIGS. 1 and 2, the pressing force and the turning force are applied to the top surface 16 of the second yoke 14 and the top surface 28 of the first yoke 24 and the pivot 20. While moving along the curved elliptical pivot hole 32, the second yoke 14 is received by rotating in the direction of arrow S in FIG. 1 along a substantially arcuate curved surface. As a result, the pivot 20
The first yoke 24 supports the second yoke 14 while the first yoke 24 does not contact the peripheral wall of the pivot hole 32. Therefore, the first
The load is distributed to the top surface 28 of the yoke 24 and the top surface 16 of the second yoke 14, and the pivot 20 and the pivot hole 32 do not receive the load.

Further, in the operating state of the vehicle wiper 10, a pressing force acts on the second yoke 14 in the axial direction of the pivot 20 (the direction of arrow Q1 or arrow Q2 in FIG. 2). In this case, as shown in FIG. 2, the pressing force is received by the side surface 18 of the second yoke 14 and the side surface 30 of the first yoke 24 abutting on each other. As a result, in a state where the pivot 20 does not contact the peripheral wall of the pivot hole 32, the first
A yoke 24 supports the second yoke 14. Therefore,
The side surface 30 of the first yoke 24 and the side surface 18 of the second yoke 14
And the pivot 20 and the pivot hole 32 receive no load.

As described above, when the vehicle wiper 10 is stopped and operated, the load conventionally concentrated on the pivot 20 and the pivot hole 32 is applied to the top surface 2 of the first yoke 24.
8 and side surface 30 and top surface 16 and side surface 1 of second yoke 14
8, since the pivot 20 and the pivot hole 32 do not receive a load, the wear and damage of the pivot 20 and the pivot hole 32 can be prevented, and the durability of the first yoke 24 and the second yoke 14 can be improved. As a result, the reliability of the vehicle wiper 10 can be improved.

Further, when the vehicle wiper 10 is operated, the peripheral wall of the pivot hole 32 does not contact the pivot 20, so that the generation of noise due to the contact between the peripheral wall of the pivot hole 32 and the pivot 20 can be prevented.

The first yoke 24 and the second yoke 14
Made of resin, the first yoke 24 and the second yoke 1
4 can be prevented, and therefore, the first yoke 24 and the second yoke 14 (including the pivot 20 and the pivot hole 32)
Can be improved in durability. Further, the weight of the first yoke 24 and the second yoke 14 can be reduced, and the cost can be reduced.

Further, a pivot hole 32 is formed in the first yoke 24.
Since the pivot 20 is formed on the second yoke 14, the pivot 20 can be easily formed. Thereby, the cost can be significantly reduced.

Further, since a joint body is not required as in the prior art, a simple configuration can be achieved. further,
An increase in the number of parts can be eliminated, thereby preventing an increase in cost. (Modification) FIG. 5 is a sectional view showing a main part of a vehicle wiper 40 according to a modification of the first embodiment.

In this modified example, instead of forming the pivot 20 in the second yoke 14 as in the first embodiment, a resin rivet 42 as a pivot is passed through the second yoke 14. I have.

Also in this modification, the same effects as in the first embodiment can be obtained.

Next, a second embodiment of the present invention will be described. In the second embodiment, the same reference numerals are given to the same components as those described in the second embodiment, and the configuration is omitted. [Second Embodiment] FIG. 6 shows a vehicle wiper 5 according to a second embodiment to which the member supporting structure of the present invention is applied.
0 is shown in a front view, and FIG. 7 is a cross-sectional view showing the main part of the vehicle wiper 50.

Vehicle Wiper 50 According to Second Embodiment
Then, the side surface 30 of the first yoke 24 of the wiper blade 12
, A column-shaped pivot 52 is formed, and the pivot 52 protrudes inward of the first yoke 24.

Further, similarly to the first embodiment, the top surface 28 of the first yoke 24 is formed into a substantially arc-shaped curved surface projecting downward.

A pivot hole 54 is formed in the vicinity of the side surface 18 of the second yoke 14, and the pivot hole 54 is formed in an elliptical shape curved along a substantially arc-shaped curved surface of the top surface 28 of the first yoke 24. Have been. The width of the pivot hole 54 is larger than the diameter of the pivot 52 of the first yoke 24. Thereby, the first yoke 24 is inserted into the pivot hole 54.
The first yoke 24 rotatably supports the second yoke 14, and the pivot 5
2 can be moved in the width direction and the longitudinal direction of the pivot hole 54.

Here, the distance (the distance B in FIG. 6) from the top surface 16 of the first yoke 24 to the side surface of the pivot 52 is the second
The distance from the top surface 28 of the yoke 14 to the peripheral wall of the pivot hole 54 (the distance A in FIG. 6) is longer. For this reason,
The direction perpendicular to the axis of the pivot 52 with respect to the second yoke 14 (FIG. 6)
In the state where the pressing force and the turning force act around the axis of the pivot 52 (in the direction of arrow P), as shown in FIGS. 6 and 7, the pressing force and the turning force are applied to the top surface 1 of the second yoke 14.
6 and the top surface 28 of the first yoke 24 abut against each other,
While the pivot 52 moves along the curved elliptical pivot hole 54, the second yoke 14 is received by being rotated in the direction of the arrow S in FIG. 6 along the substantially arcuate curved surface, thereby receiving the pivot 52. The first yoke 24 supports the second yoke 14 in a state in which the first yoke 24 does not contact the peripheral wall of the pivot hole 54.

When a pressing force acts on the second yoke 14 in the axial direction of the pivot 52 (in the direction of arrow Q1 or arrow Q2 in FIG. 7), as shown in FIG. 14 and the side surface 30 of the first yoke 24 come into contact with each other, thereby receiving the pivot 5.
The first yoke 24 is configured to support the second yoke 14 in a state where the second yoke 24 does not contact the peripheral wall of the pivot hole 54.

Next, the operation of the present embodiment will be described.

In the vehicle wiper 50 having the above configuration,
In a state where the wiper blade 12 is separated from the windshield glass, no arm pressure acts on the wiper blade 12, so that no pressing force in the direction of the first yoke 24 acts on the second yoke 14. In such a state, the second
When the pivot 52 of the yoke 14 abuts on the peripheral wall of the pivot hole 54 of the first yoke 24, the first yoke 24 supports the second yoke 14, so that the second yoke 14 falls off from the first yoke 24. Can be prevented.

When the vehicle wiper 50 is stopped (when the wiper blade 12 is in contact with the windshield glass), arm pressure acts on the wiper blade 12, so that the pivot 52 is perpendicular to the second yoke 14 in the direction perpendicular to the axis (see FIG. 6 (in the direction of arrow P). In such a state, as shown in FIGS. 6 and 7, the pressing force is received when the top surface 16 of the second yoke 14 and the top surface 28 of the first yoke 24 abut. Thus, the first yoke 24 supports the second yoke 14 in a state where the pivot 52 does not contact the peripheral wall of the pivot hole 54. Therefore, the load is distributed to the top surface 28 of the first yoke 24 and the top surface 16 of the second yoke 14, and the pivot 52 and the pivot hole 54 do not receive the load.

In the operating state of the vehicle wiper 50, a pressing force acts on the second yoke 14 in a direction perpendicular to the axis of the pivot 52 (the direction of the arrow P in FIG. 6), and the windshield glass is curved. A rotating force acts on the second yoke 14 around the axis of the pivot 52. In such a state, as shown in FIGS. 6 and 7, the pressing force and the turning power are applied to the top surface 16 of the second yoke 14 and the top surface 28 of the first yoke 24 and the pivot 52. While moving along the curved elliptical pivot hole 54, the second yoke 14 is received by rotating in the direction of arrow S in FIG. 6 along a substantially arc-shaped curved surface. Thereby, the pivot 52
The first yoke 24 supports the second yoke 14 while the first yoke 24 does not contact the peripheral wall of the pivot hole 54. Therefore, the first
The load is distributed to the top surface 28 of the yoke 24 and the top surface 16 of the second yoke 14, and the pivot 52 and the pivot hole 54 do not receive the load.

Further, in the operating state of the vehicle wiper 50, a pressing force acts on the second yoke 14 also in the axial direction of the pivot 52 (the direction of the arrow Q1 or Q2 in FIG. 7). In this case, as shown in FIG. 7, the pressing force is received by the contact between the side surface 18 of the second yoke 14 and the side surface 30 of the first yoke 24. Thus, the first pivot 52 is not in contact with the peripheral wall of the pivot hole 54 and the first
A yoke 24 supports the second yoke 14. Therefore,
The side surface 30 of the first yoke 24 and the side surface 18 of the second yoke 14
And the pivot 52 and the pivot hole 54 receive no load.

As described above, when the vehicle wiper 50 is stopped and operated, the load conventionally concentrated on the pivot 52 and the pivot hole 54 is applied to the top surface 2 of the first yoke 24.
8 and side surface 30 and top surface 16 and side surface 1 of second yoke 14
8, since the pivot 52 and the pivot hole 54 are not loaded, the wear and damage of the pivot 52 and the pivot hole 54 can be prevented, and the durability of the first yoke 24 and the second yoke 14 can be improved. Thus, the reliability of the vehicle wiper 50 can be improved.

Furthermore, since the peripheral wall of the pivot hole 54 does not come into contact with the pivot 52 when the vehicle wiper 50 is operated, generation of noise due to contact between the peripheral wall of the pivot hole 54 and the pivot 52 can be prevented.

The first yoke 24 and the second yoke 14
Made of resin, the first yoke 24 and the second yoke 1
4 can be prevented, and therefore, the first yoke 24 and the second yoke 14 (including the pivot 52 and the pivot hole 54).
Can be improved in durability. Further, the weight of the first yoke 24 and the second yoke 14 can be reduced, and the cost can be reduced.

Further, since a joint body is not required as in the related art, a simple configuration can be achieved. further,
An increase in the number of parts can be eliminated, thereby preventing an increase in cost. (Modification) FIG. 8 is a sectional view showing a main part of a vehicle wiper 70 according to a modification of the second embodiment.

In this modified example, instead of forming the pivot 52 in the first yoke 24 as in the above-described second embodiment, a resin rivet 72 as a pivot is passed through the first yoke 24. I have.

In this modification, the same effects as those of the second embodiment can be obtained.

In the above embodiment (including the modification), the first yoke 24 and the second yoke 14 of the wiper blade 12 are made of resin. However, the first yoke and the second yoke may be made of metal. Good.

Further, in the above-described embodiments (including the modifications), the structure of the pivot joint between the first yoke 24 and the second yoke 14 of the wiper blade 12 has been described.
