[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be specifically described with reference to FIGS. 1 to 5.
[0013]
Reference numeral 1 denotes a wiper of the present invention. The wiper 1 has a long refill 3 having a wiping portion 3a capable of wiping a wiping surface 2a of a wiping member 2 such as a front wind panel of an automobile, and the refill. The first vertical bar 4 is formed so as to be able to be held in a state of being engaged with the holding portion 3b of the third refill 3 and is formed to be substantially the same length as the refill 3; A second vertebra 5, which is combined and shorter than the first vertebra 4, a driving member 6 capable of wiping the refill 3 and the driving member 6 and the first and second vertebras 4, 5 are connected. It comprises at least a connecting member 7 and a cover 8 having a cross-sectional shape which is engaged with the first vertebra 4 and urges the refill 3 against the wiping surface 2a against wind pressure.
[0014]
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 portion 11 is formed by bending the end portion 10a of the general portion 10 at a predetermined angle θ so as to be along a portion opposed to a large curvature of the wiping surface 2a of the wiping member 2. A plurality of claws 12 each having a width of 3 mm are formed on the side surfaces of the general portion 10 and the pressing portion 11. A first engaging portion 13 is formed in the middle of the first vertebra 4, that is, in the general portion 10, and both end sides of the first vertebra 4, that is, the other end 10 b of the general portion 10 and the other end of the pressing portion 11. The second engaging portions 14 are formed on the portion 11a.
[0015]
The second vertebra 5 is formed 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-shaped" shape. An elastic force for pressing the refill 3 toward the wiping surface 2a is provided through one vertebra 4.
[0016]
The refill 3 includes the wiping portion 3a, the holding portion 3b, and a neck portion 3c formed between the holding portion 3b and the wiping portion 3a, and has an overall length of, for example, 550 mm. Is formed. The holding portion 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 By the engagement of 12, the first vertebra 4, the second vertebra 5, and the refill 3 are integrally polymerized.
[0017]
The first engaging portion 13 bridges 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. I have. The second engaging portion 14 bridges a not-shown notch of the first vertebra 4 at a position of 6 mm in the width direction, 4 mm in the longitudinal direction (longitudinal direction), and 1.4 mm in depth. .
[0018]
The bent portion 5a of the second vertebra 5 is provided with a third engaging portion 17 which is 9 mm long in the longitudinal direction and rises 2 mm upward. A fourth engaging portion 18 is formed at one end 5b of the second vertebra 5 such that it is 4 mm long in the longitudinal direction and rises 2 mm upward and is chamfered at 60 degrees.
[0019]
The assembling state of the wiper 1 configured as described above will be described below. First, as shown in FIG. 4, the first vertebra 4 and the second vertebra 5 are arranged such that the second vertebra 4 is disposed below the first vertebra 4 so that the first engagement portion of the first vertebra 4 is formed. The third engaging portion 17 of the second vertebra 5 is engaged with the upper side of the 13. Next, the end of the second vertebra 5 is inserted through the opening of the first vertebra 4, and the fourth engagement portion 18 of the second vertebra 5 is inserted into the second engagement portion 14 through the opening of the first vertebra 4. Is locked. By doing so, the first vertebra 4 in the form of a flat plate is held in a state of being bent in an arc by the second vertebra 5 bent in the lower chord. 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.
[0020]
Next, as shown in FIG. 4, in a state where the first vertebra 4 and the second vertebra 5 are assembled, the claw 12 of the first vertebra 4 has the second groove 16 of the refill 3 open. And the second groove 16 and the claw 12 are engaged with each other. When the claw 12 reaches one of the closed ends of the second groove 16, it hits the cap 20 having an L-shaped cross section engaged with the first vertebra 4. At this time, at the same time, the free end of the claw 12 goes over the projection (not shown) of the second groove 16 and re-enters the recess of the second groove 16, so that the refill 3 is moved to the first and second vertebras 4 and 5. This assembling work is completed by being able to prevent the assembling from falling off. Further, the refill 3 is held by a set of the first vertebra 4 and the second vertebra 5 which 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.
[0021]
The cap 20 is in contact with the end of the cover 8 as shown in FIG. 1, and the cover 8 attaches the leg 8 a of the cover 8 to the first vertebra 4 as shown in FIG. 3. The notch 21 faces the notch 21 and is engaged with and supported by the notch 21.
[0022]
The cover 8 is made of a material such as flexible rubber or plastic. The cover 8 is provided above the first vertebra 4 and the second vertebra 5 so as to protect the first vertebra 4 and the second vertebra 5. So it is held. The cross section of the cover 8 is low on one side and high on the other side, and is formed in a ridge-like shape at the high portion so as to be easily affected by wind pressure and the like accompanying traveling. Since the wiping portion 3a of the refill 3 is designed so as not to float from the wiping surface 2a of the wiping member 2, the wiping property is maintained.
[0023]
In the wiper 1 having the above configuration, when the wiping portion 3a of the refill 3 is deteriorated, only the refill 3 is replaced by making the claws 12 formed on the first bar tabler 4 enter and exit the second groove 16 of the refill 3. This makes it possible to eliminate the need to replace the entire wiper 1. This results in effective use of resources and reduction of the burden on consumers. Depending on the specifications of the refill 3, there are a refill for wiping raindrops and a refill for removing snow. However, 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. In addition, since the combined body of the first and second vertebras 4 and 5 is held by the pawls 12, the overall height is reduced, the rolling during operation of the wiper 1 is reduced, and the wear resistance of the refill 3 is improved. I do.
[0024]
Also, since the first and second vertebras 4 and 5 are formed by bending in an arc shape, the refill 3 supported thereon is urged to rotate toward the wiping surface 2a. In spite of the wiper 1 having no wiper, the wiper 1 can be pressed flush against the wiping surface 2a. 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.
[0025]
Further, the first vertebra 4 and the second vertebra 5 are connected by a first engaging portion 13 and a third engaging portion 17 at a central portion and at an end by a second engaging portion 14 and a fourth engaging portion. The two and the four can be joined and supported only by being engaged with the joint part 18, so that assembly is simple and easy.
[0026]
Further, the refill 3 can be pressed against the wiping surface 2a by the cover 8, so that not only the floating of the wiper 1 can be prevented, but also decorative addition is possible.
[0027]
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 most other surfaces, the pressing portion 11 of the first vertebra 4 is bent in advance. Therefore, 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 can follow well when the curvature of the wiping surface 2a is small. In either case, the wiping portion 3a of the refill 3 does not separate from the wiping surface 2a, and the wiping performance is significantly improved.
[0028]
【The invention's effect】
According to the first aspect of the present invention, even if the curvature of the wiping surface is larger than most of the other surfaces, the wiping surface can follow because the pressing portion of the first flat bar is bent in advance. It is possible that the pressing portion is in a non-polymerized state with respect to the second vertibra bent in a lower chord shape, so that when the curvature of the wiping surface is small, the pressing portion is firmly held in a state of being bent in an arc shape. In both cases, the wiping portion of the refill does not separate from the wiping surface, leaving no wiping, and the wiping performance is significantly improved. That is, by appropriately setting the bending dimension, the plate thickness, the hardness, and the like of the second vertebra, it is possible to appropriately cope with the pressing force from the driving member, the curve of the wiping member, and the like.
[0029]
According to the invention of claim 2, a claw capable of holding the holding portion of the refill is formed intermittently in the longitudinal direction in the first vertebra, and the claw is provided on the claw in the longitudinal direction in the long direction. Since a groove that can be engaged is formed from the end of the first vertical bar and the combined body of the first and second vertical bars is held by the pawl, the overall height is reduced, and rolling during operation of the wiper is reduced. The abrasion resistance of the refill is improved.
