At least.

The first vertebra 4 is made of a stainless steel plate having a thickness of 0.6 mm, and is formed of a long flat plate having a total length of 550 mm and a total width of 12 mm. The first vertebra 4 includes a general portion 10 occupying most of the portion and a pressing portion 11 formed at one end 10a. The general portion 10 and the pressing portion 11 are both formed in a planar shape. The pressing part 1
1 is an end portion 10 of the general portion 10 so as to be along a portion opposed to a large curvature of the wiping surface 2a of the wiping member 2.
and is formed by bending at a predetermined angle θ from “a”. A plurality of claws 12 having a width of 3 mm are formed on the side surfaces of the general portion 10 and the pressing portion 11. In the middle of the first vertebra 4, that is, in the general portion 10,
A first engaging portion 13 is formed, and the second engaging portions 14 and 1 are provided at both ends of the first vertebra 4, that is, at the other end 10 b of the general portion 10 and the other end 11 a of the pressing portion 11.
4 are formed.

The second vertebra 5 is formed so as to be shorter and flatter than the general portion 10 of the first vertebra 4, and is formed by bending the lower chord bending portion 5a into a "L" shape. An elastic force for pressing the refill 3 toward the wiping surface 2a via the first vertebra 4 is provided.

The refill 3 comprises the wiping part 3a, the holding part 3b, and a neck part 3c formed between the holding part 3b and the wiping part 3a, and has a total length of, for example, 550 mm. It is formed in a long shape. The holding section 3b is formed in a square cross section as shown in FIG. The holding portion 3b is formed with two first grooves 15 and a second groove 16 which is a "groove" at positions vertically separated from each other, and the second groove 16 has a claw of the first vertebra 4. 12 is engaged, the first vertebra 4 and the second
The vertebra 5 and the refill 3 are integrally polymerized.

The first engaging portion 13 is provided with a notch (not shown) of the first vertebra 4 at a position of 6 mm in the width direction, 10 mm in the longitudinal direction (longitudinal direction), and 1.4 mm in depth. Crosslinked. 2nd engagement part 1
4 is 6 millimeters in the width direction, long direction (longitudinal direction)
At a position of 4 mm and a depth of 1.4 mm,
The notch (not shown) of the first vertebra 4 is bridged.

The bent portion 5a of the secondvertebra 5
Is formed with a third engaging portion 17 which is 9 mm long in the longitudinal direction and rises 2 mm upward. One end 5b of the second vertebra 5 has a lengthwise direction
A fourth engaging portion 18 is formed in millimeters, which is raised 2 millimeters upward and is formed with a 60-degree chamfer.

Next, the assembling state of the wiper 1 configured as described above will be described. First, as shown in FIG. 4, the first vertebra 4 and the second vertebra 5 are arranged such that the second vertebra 5 is disposed below the first vertebra 4, so that the first engagement portion of the first vertebra 4 is formed. The second above 13
The third engaging portion 17 of the vertical bra 5 is engaged. next,
Through the opening of the first vertebra 4, the second vertebra 5
Is inserted into the second engaging portion 14 through the opening of the first vertebra 4 and the fourth engaging portion 18 of the second
Is locked. By doing so, the first vertebra 4 in the form of a flat plate is replaced with the second vertebra 5 which is bent in a lower chord.
Thereby, it is held in a state of being bent in an arc shape. That is, by appropriately setting the bending dimension, plate thickness, hardness, and the like of the second vertebra 5, it is possible to appropriately respond to the pressing force from the driving member 5, the curve of the wiping member 2, and the like. Then, the pressing portion 11 of the first vertebra 4 protruding from the other end 5c of the second vertebra 5 is lower by a predetermined angle θ ′ with respect to the uniform arc line 19 shown by the two-dot chain line in FIG. It is located in. The position of the other end 5c of the second vertebra 5 is a position where the curvature of the large curvature surface 2b of the wiping surface 2a stops.

Next, as shown in FIG. 4, in the assembled state of the first vertebra 4 and the second vertebra 5, the claws 12 of the first vertebra 4 are inserted into the second grooves 1 of the refill 3.
The second groove 16 and the claw 12 are engaged by applying and shifting the other open end of 6. When the claw 12 reaches one of the closed ends of the second groove 16, the cap 20 having an L-shaped cross section engaged with the first vertebra 4
Hit. At this time, at the same time, the free end of the claw 12 climbs over the protrusion (not shown) of the second groove 16 and re-enters the recess of the second groove 16, so that the refill 3 can be connected to the first and second vertebras 4 and 5. This assembling work is completed by being able to prevent falling off from the assembled one. Further, the refill 3 is held by a set of the first vertebra 4 and the second vertebra 5 that are fixed in a state of being bent in an arc, so that the refill 3 itself also becomes an arc, and the second vertebra is formed. The refill 3 attached to the portion pressed down by the pressing portion 11 has a large curvature.

The cap 20 is, as shown in FIG.
The cover 8 is in contact with the end of the cover 8,
As shown in FIG. 3, the leg 8 a of the cover 8 faces the notch 21 of the first vertebra 4 and is engaged with and supported by the notch 21.

The cover 8 is made of a material such as flexible rubber or plastic. The upper cover of the first and second vertebras 4 and 5 protects the first and second vertebras 4 and 5. As described above. One of the cross sections of the cover 8 is low,
The other is high, and in the high part, it is formed in a bank shape,
The wiping portion 3a of the refill 3 of the wiper 1 is formed in a shape that easily receives wind pressure and the like accompanying running.
Is designed so that it does not rise from the wiping surface 2a of the wiping member 2, so that the wiping performance is maintained.

When the wiping portion 3a of the refill 3 is deteriorated, the wiper 1 having the above-described structure allows the claw 12 formed on the first bartabra 4 to enter and exit the second groove 16 of the refill 3 so that only the refill 3 is provided. Can be replaced, and the entire wiper 1 does not need to be replaced. This results in effective use of resources and reduction in the burden on consumers. In addition, depending on the specifications of the refill 3, there are a refill for wiping raindrops and a refill for removing snow, but in the case of such replacement, only the refill 3 needs to be replaced, and the entire wiper 1 does not need to be replaced. Will be. This also results in effective use of resources and reduction of the burden on consumers. Further, the first vertebra 4 and the second
Since the combined body with the vertebra 5 is held, the overall height is reduced, the rolling during the operation of the wiper 1 is reduced, and the wear resistance of the refill 3 is improved.

Further, the first vertebra 4 and the second vertebra 5 are formed by bending in an arc shape.
Since the refill 3 supported thereon is urged to rotate toward the wiping surface 2a, it can be pressed flush against the wiping surface 2a despite the fact that the wiper 1 has no pressing means such as a spring. In addition, since the first and second vertebras 4 and 5 are connected and supported, the refill 3 is reliably supported by the connecting member 7 via the first and second vertebras 4 and 5.

Also, the first vertebra 4 and the second
The center of the vertebra 5 is formed by the first engagement portion 13 and the third engagement portion 17, and the end portion is formed by the second engagement portion 14 and the fourth engagement portion 14.
The two and the four can be connected and supported only by being engaged with the engagement part 18, so that assembly is simple and easy.

Further, since the refill 3 can be pressed against the wiping surface 2a by the cover 8, not only the floating of the wiper 1 can be prevented, but also decorative addition is possible.

In particular, even if the curvature of the wiping surface 2a is not uniform and, for example, the curvature of the large curvature surface 2b is larger than that of most other surfaces, the pressing portion 11 of the first vertebra 4 is not Since it is bent in advance, it is possible to follow the wiping surface 2a, and since the pressing portion 11 is in a non-polymerized state with respect to the second vertebra 5, it is often used when the curvature of the wiping surface 2a is small. In both cases, the wiping portion 3a of the refill 3 does not separate from the wiping surface 2a, and the wiping performance is significantly improved.

[0028]

According to the first aspect of the present invention, even if the wiping surface has a curvature larger than most other surfaces, the wiping surface follows because the pressing portion of the first vertebra is bent in advance. Since the pressing portion is in a non-polymerized state with respect to the second vertebra, it can follow well when the curvature of the wiping surface is small, and in both cases, the wiping portion of the refill There is no separation from the surface, no wiping remains, and the wiping performance is significantly improved.

According to the second aspect of the present invention, a claw capable of holding the holding portion of the refill is intermittently formed on the first vertebra, and the claw is engaged with the claw from one side. Since a possible groove portion is formed, the combined body of the first and second vertebras is held by the claws, so that the overall height is reduced, the rolling during the operation of the wiper is reduced, and the abrasion resistance of the refill. Is improved.

According to the third aspect of the present invention, since the refill can be pressed against the wiping surface by the cover, not only can the wiper be prevented from being lifted up, but also a decorative addition can be made.
