Fig. 2 is the section drawing along Fig. 1 middle section line A-A.Fig. 3 A and Fig. 3 B are the scheme drawing of the details of expression rubber retainer retaining part shown in Figure 1; As shown in Figure 2, the sheet rubber 16 that uses in this wiper blade 11 is by making as similar materials such as natural rubber or neoprene, and forms the strip that end wise has uniform cross-section.Sheet rubber 16 has head 21, and the connecting bridge 22 and the lip 23 that extend to head 21, and like this, lip 23 contacts with Windshield 13.Lip 23 is connected in connecting bridge 22 by neck 24.Neck 24 forms narrower than connecting bridge 22 and the width of lip 23 on the wiping direction at the width on the wiping direction, thus lip 23 can be on the wiping direction head 21 and connecting bridge 22 freely tilt relatively.
Two wiping direction sides at head 21 are formed with respectively along the recessed mounting groove 25 of wiping direction.These mounting grooves 25 form respectively, so that extend along its length, arrive the other end with the length direction along head 21 from an end, and each mounting groove 25 setting on the wiping direction are in the state that is isolated from each other by partitioned portion 26.And, in mounting groove 25, be separately installed with sheet spring spare (vertebra) 27.
Sheet spring spare 27 forms writing board shape by punching press and processing as the sheet material of steel plate, has and the similar length dimension of sheet rubber 16 length dimensions sheet spring spare 27 elastically deformable on perpendicular to the direction of Windshield 13.Therefore, the sheet rubber 16 that sheet spring spare 27 is housed can that is to say with sheet spring spare 27 elastic deformations on perpendicular to the direction of Windshield 13, changes on the direction of degree of crook at glass surface relatively.And on free elastic deformation direction, sheet spring spare 27 has the curvature bigger than the curvature of Windshield 13 in state of nature, thereby the sheet rubber 16 that sheet spring spare 27 is housed is also crooked more than Windshield 13 under the state that leaves Windshield 13.
In addition, when representing in the accompanying drawings, use be the sheet spring spare of making by steel plate 27.But the present invention is not limited to this, for example, can use the sheet spring spare of being made by materials such as animi resin, perhaps can use can other material of elastic deformation be made on perpendicular to the direction of Windshield 13 sheet spring spare.
On the other hand, rubber retainer 15 is made by resin material, form the shape in U-shaped cross section, and have top wall portion 15a and pair of sidewalls part 15b, sidewall sections 15b is connected to each other by top wall portion 15a, and substantially parallel along its length opening, wherein, the axial length dimension of rubber retainer 15 is set to the only about half of of sheet rubber 16 axial lengths.The centre portion of top wall portion 15a length direction has mounting portion 28, and rubber retainer 15 is connected in the end of Windshield Wiper swing arm 14 by this mounting portion 28.When being installed on sheet rubber 16 on the rubber retainer 15, the upper surface of sheet rubber 16 heads 21 is covered by the top wall portion 15a of rubber retainer, the left and right side surface of head 21 (along the two side portions of wiping direction) end wise is covered by two sidewall sections 15b, that is to say that the centre portion end wise of sheet rubber 16 heads 21 is centered on by rubber retainer.Therefore, when sheet rubber 16 abutted against on the Windshield 13, because end wise does not form the gap between rubber retainer 15 and sheet rubber 16, therefore, the present invention had outstanding layout characteristics.
In addition, rubber retainer 15 is not limited to be formed from a resin, and can be made by materials such as metallic materials.
End on rubber retainer 15 length directions (when wiper blade 11 is connected in Windshield Wiper swing arm 14, near the nearer end of Windshield Wiper swing arm 14 center of oscillation) has retaining part 31.The other end on rubber retainer 15 length directions has retaining part 32.
As shown in Figure 3A, retaining part 31 as first connecting device has a pair of first maintenance pawl 33, integrally form with sidewall sections 15b respectively (below be called and keep pawl 33, though only express a side among the figure, but has identical maintenance pawl 33 at opposite side), keep pawl 33 to form the outstanding shape of square-section, from sidewall sections 15b towards perpendicular to sheet rubber 16 length directions and to be parallel to the direction of wiping direction outstanding.On the other hand, between the head 21 and lip 23 of sheet rubber 16, be formed with a pair of maintenance groove 35 that head 21 separates and the arm portion 34 that forms at connecting bridge 22, to extend along its length.Each keeps pawl 33 to be separately positioned in the corresponding maintenance groove 35.That is to say that the head 21 of sheet rubber 16 is by keeping pawl 33, two sidewall sections 15b and top wall portion 15a to center on, thereby retaining part 31 keeps head 21.
In addition, have a pair of stop portion 36 in sheet rubber 16, correspond respectively to maintenance groove 35, the maintenance pawl 33 that is positioned at retaining part 31 is arranged at stop portion 36.As shown in Figure 3A, stop portion 36 has a pair of protuberance 36a and the 36b that gives prominence to respectively in keeping groove 35, and protuberance 36a and 36b separate every the spacing of regulation along its length.Each of retaining part 31 keeps pawl 33 to be set to press from both sides between a pair of protuberance 36a and 36b corresponding to the stop portion 36 of this maintenances pawl, thus constraint moving along the maintenance groove relative sheet rubber 16 of 35 directions.That is to say that sheet rubber 16 is connected in rubber retainer 15, also keep that sheet rubber 16 is in the state of locating on the length direction in the retaining part 31 by rubber retainer 15.
By same way as, shown in Fig. 3 B, retaining part 32 as second connecting device has a pair of second maintenance pawl 37, integrally form with sidewall sections 15b respectively (below be called and keep pawl 37, though only express a side among the figure, but have identical maintenance pawl 37 at opposite side), keep pawl 37 to form the outstanding shape of square-sections, from sidewall sections 15b towards perpendicular to the length direction of sheet rubber 16 and to be parallel to the direction of wiping direction outstanding.Each keeps pawl 37 to be separately positioned in the corresponding maintenance groove 35, thereby the head 21 that makes sheet rubber 16 is by keeping pawl 37, two sidewall sections 15b and top wall portion 15a to surround, and is kept by retaining part 32.That is to say that stop portion 36a and 36b are not positioned at the position corresponding to the retaining part 32 that keeps groove 35, and sheet rubber 16 is connected in rubber retainer 15, promptly keeps, be in and keep the pawl 37 can be along the state that keeps groove 35 to move by rubber retainer 15.
Fig. 4 A to Fig. 4 D is the scheme drawing of expression sheet rubber alteration of form when wiper blade shown in Figure 1 contacts with Windshield.When sheet rubber 16 did not contact Windshield 13, shown in Fig. 4 A, this wiper blade 11 had than the also big curvature of maximum curvature in the Windshield 13 wiping scopes along the direction bending of closing towards glass surface.When from then on wiper blade 11 places on the Windshield 13 under the state, two ends contact glass surfaces on sheet rubber 16 length directions at first.Under two ends and glass surface state of contact of sheet rubber 16, when the pressure (shown in the arrow among the figure) of Windshield Wiper swing arm 14 when acting on sheet rubber 16 by rubber retainer 15, shown in Fig. 4 B, sheet rubber 16 is deformed into M shape, thereby, the core contact glass surface of length direction.At this moment, sheet rubber 16 suffers restraints at retaining part 31 in the axial relatively motion of rubber retainer 15, and sheet rubber 16 allows at the axial motion of retaining part 32, like this, when the pressure of Windshield Wiper swing arm 14 increased, sheet rubber 16 can be out of shape along glass surface.And shown in Fig. 4 C, sheet rubber 16 distortion are so that arrive the state that is attached to glass surface gradually.When being attached to glass surface fully, shown in Fig. 4 D, sheet rubber arrives wiping position, and in this position, the whole end wise of sheet rubber passes through to contact with glass surface at the pressure of Windshield Wiper swing arm 14.At this moment, sheet spring spare 27 is also according to the shape of the mode elastic deformation identical with sheet rubber 16 for carrying over glass surface.Therefore, Windshield Wiper swing arm 14 acts on the pressure of rubber retainer 15 by mounting portion 28, be scattered in the length direction of sheet rubber 16 by the elastic deformation of sheet spring spare 27, and sheet rubber 16 contacts with Windshield 13 by well-distributed pressure on the length direction.Therefore, sheet rubber 16 can be carried out wiping operation in following state: the integral body on sheet rubber 16 length directions contacts with Windshield 13 equably, and brings preferable wiping properties.
As mentioned above, in this wiper blade 11, sheet rubber 16 has retaining part 31 and 32 in two ends of rubber retainer 15 length directions, and wherein, retaining part 31 and 32 remains in sheet rubber 16 on two points.Therefore, when the pressure of Windshield Wiper swing arm 14 acts on rubber retainer 15 by mounting portion 28, pressure is from 2 points of 15 two ends of rubber retainer, promptly from each retaining part 31 and 32 and corresponding to two ends from top wall portion 15a of each retaining part 31 and 32, act on along two parts of the both sides in 4 positions that sheet rubber 16 length directions separate, thereby, various piece has length (apart from the position of sheet rubber 16 end portion 1/4 overall length) much at one, and pressure is from two compacted position rectangular distribution along its length.Therefore, can sheet rubber 16 flexibly be pressed on the Windshield 13 with well-distributed pressure, thereby end wise does not change under the wide situation of the thickness of slab of the sheet spring spare 27 that is installed on the sheet rubber 16 or plate, sheet rubber 16 can be pressed on the glass surface equably.In addition, owing to allow sheet rubber 16 to slide at the relative retaining part 32 of rubber retainer 15 1 sides, so sheet rubber 16 can apply pressure more uniformly on Windshield 13.And, when rubber retainer 15 is suitable for the relative rubber retainer 15 of sheet rubber 16 and sheet rubber 16 end wises and slides from the outside, sheet rubber 16 can be inserted in the rubber retainers 15.Therefore, can simplify the structure of wiper blade 11, and carry out fitting work easily, thereby improve operability.And, cover sheet rubber 16 from the outside according to the rubber retainer 15 of such installation, and, when sheet rubber 16 contact glass surfaces, between rubber retainer 15 and sheet rubber 16, can not form the gap.Therefore, can improve layout characteristics, i.e. the beautiful outward appearance of wiper blade 11.
Further, in this wiper blade 11, because sheet rubber 16 is by keeping pawl 33 and 37 to keep, keep pawl 33 and 37 to be positioned at the position nearer apart from Windshield 13 than sheet spring spare 27, therefore, with the position of more close Windshield 13 as pivot shaft in, sheet rubber 16 is swung to glass surface.Thereby can improve the tack of sheet rubber 16 and Windshield 13, make wiper blade have outstanding wiping properties and layout characteristics.
